To compare proximal gastrectomy (PG) with total gastrectomy (TG) for proximal gastric carcinoma, through the 5-year survival rate, recurrence rate, postoperative complications, and long-term life quality. The meta-analysis was carried out in the General Surgery Department of the Second Affiliated Hospital of Soochow University, Suzhou, Jiangsu Province, China. We searched Medline, EMBASE, and the Cochrane Library from June to November 2012. The literature searches were carried out using medical subject headings and free-text word: `proximal gastrectomy` `total gastrectomy` `partial gastrectomy` `stomach neoplasms` and `gastric cancer`. Two different reviewers carried out the search and evaluated studies independently. Two randomized controlled trials and 9 retrospective studies were included. A total of 1364 patients were included in our study. Our analysis showed that there is no statistically significant difference in 5-year survival rate between PG and TG (60.9% versus 64.4%). But, the recurrence is higher in the PG group than the TG (38.7% versus 24.4%). The anastomotic stenosis rate is also higher in the PG than the TG (27.4% versus 7.4%). Proximal gastrectomy is an option for upper third gastric cancer in terms of safety. However, it is associated with high risk of reflux symptoms and anastomotic stenosis. Therefore, TG should be the first choice for proximal gastric cancer to prevent reflux symptoms.

Mesh fixation during laparoscopic totally extraperitoneal repair is thought to be necessary to prevent recurrence. However, mesh fixation may increase postoperative chronic pain. This study aimed to describe the experience of a single surgeon at our institution performing this operation. We performed a retrospective review of the medical records of all patients who underwent bilateral laparoscopic totally extraperitoneal repair without mesh fixation for inguinal hernia from January 2005 to December 2011. Demographic, operative, and postoperative data were obtained for analysis. A total of 343 patients underwent simultaneous bilateral laparoscopic totally extraperitoneal repair of 686 primary and recurrent inguinal hernias from January 2005 to December 2011. The mean operative time was 33 minutes. One patient was converted to an open approach (0.3%), and 1 patient had intraoperative bladder injury. Postoperative hematoma/seroma occurred in 5 patients (1.5%), wound infection in 1 (0.3%), hematuria in 2 (0.6%), and acute myocardial infarction in 1 (0.3%). Chronic pain developed postoperatively in 9 patients (2.6%); 3 of them underwent re-exploration. All patients were discharged home a few hours after surgery except for 3 patients. Among the 686 hernia repairs, there were a total of 20 recurrences (2.9%) in 18 patients (5.2%). Two patients had bilateral recurrences, whereas 16 had unilateral recurrences. Twelve of the recurrences occurred after 1 year (60%). Fourteen recurrences occurred among direct hernias (70%). Compared with the literature, our patients had fewer intraoperative and postoperative complications, less chronic pain, and no increase in operative time or length of hospital stay but had a slight increase in recurrence rate.

It is well accepted that recurrent laryngeal nerve paralysis is a severe complication of esophagectomy or lymphadenectomy performed adjacent to the recurrent laryngeal nerves. Herein, determination of the effectiveness of implementing continuous recurrent laryngeal nerve monitoring to reduce the incidence of recurrent laryngeal nerve paralysis after esophagectomy was sought. A total of 115 patients diagnosed with esophageal cancer were enrolled in the thoracic section of the Tangdu Hospital of the Fourth Military Medical University from April 2008 to April 2009. Clinical parameters of patients, the morbidity, and the mortality following esophageal resection were recorded and compared. After the surgery, a 2-year follow up was completed. It was found that recurrent laryngeal nerve paralysis and postoperative pneumonia were more frequently diagnosed in the patients that did not receive continuous recurrent laryngeal nerve monitoring (6/61 vs. 0/54). Furthermore, positive mediastinal lymph nodes (P = 0.015), total mediastinal lymph nodes (P < 0.001), positive total lymph nodes (P = 0.027), and total lymph nodes (P < 0.001) were more often surgically removed in the patients with continuous recurrent laryngeal nerve monitoring. These patients also had a higher 2-year survival rate (P = 0.038) after surgery. It was concluded that continuous intraoperative recurrent laryngeal nerve monitoring is technically safe and effectively identifies the recurrent laryngeal nerves. This may be a helpful method for decreasing the incidence of recurrent laryngeal nerve paralysis and postoperative pneumonia, and for improving the efficiency of lymphadenectomy. © 2012 Copyright the Authors.

To compare the differences in recurrence rates and surgical complications between thyroidectomy alone and thyroidectomy combined with central neck dissection as initial treatments to differentiated thyroid cancer and evaluate the clinic significance of central neck dissection for these patients. The literatures published in 1998-2013 were searched in Wanfang database, Chongqing VIP database, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, Pubmed, Medline and Beijing Kangjian foreign medical journal full text service. According to the inclusion and deletion criteria, 30 articles were included. Of them 26 articles involved in complications, hypocalcemia and recurrent laryngeal nerve palsy as two major complications were involved in 26 articles and 24 articles respectively, and 26 articles involved in recurrence rate. RevMan5.0 software package was used to perform meta-analysis. Total complication rate in experimental group (plus central neck dissection) was 13.08% higher than that in control group (thyroidectomy only), the odds ratio (OR) [95% confidence interval (95%CI)] was 2.32[2.02, 2.67], Z value was 11.80, P < 0.01. Hypocalcemia in the experimental group was 11.80% higher than that in control group, OR value [95%CI] was 2.58[2.21, 3.02], Z was 11.98, P < 0.01. The rates of recurrent laryngeal nerve paralysis were low in both experimental group (5.26%) and control group(3.95%), and OR value [95%CI] was 1.22 [0.94, 1.58], Z was 1.48, P = 0.14. Recurrence rate in experimental group was 2.23% lower than that in control group, OR value [95%CI] was 0.78 [0.63,0.97], Z was 2.35, P = 0.03. Central compartment dissection as initial treatment to differentiated thyroid cancer may reduce the risk of recurrence, but increases the incidence of total complications and hypocalcemia, and has no significant effect on the rate of the recurrent laryngeal nerve paralysis.

To determine the attributable inpatient costs of recurrent Clostridium difficile infections (CDIs). Retrospective cohort study. Academic, urban, tertiary care hospital. A total of 3,958 patients aged 18 years or more who developed an initial CDI episode from 2003 through 2009. Data were collected electronically from hospital administrative databases and were supplemented with chart review. Patients with an index CDI episode during the study period were followed up for 180 days from the end of their index hospitalization or the end of their index CDI antibiotic treatment (whichever occurred later). Total hospital costs during the outcome period for patients with recurrent versus a single episode of CDI were analyzed using zero-inflated lognormal models. There were 421 persons with recurrent CDI (recurrence rate, 10.6%). Recurrent CDI case patients were significantly more likely than persons without recurrence to have any hospital costs during the outcome period (P < .001). The estimated attributable cost of recurrent CDI was $11,631 (95% confidence interval, $8,937-$14,588). The attributable costs of recurrent CDI are considerable. Patients with recurrent CDI are significantly more likely to have inpatient hospital costs than patients who do not develop recurrences. Better strategies to predict and prevent CDI recurrences are needed.

Evaluation of the intravesical instillation of doxorubicin for its effect on disease recurrence for patients with non-invasive bladder tumour. The study was performed at Al Assad University Hospital in Lattakia, Syria and included patients with non-invasive bladder tumours who were managed with transurethral resection and induction and maintenance therapy with intravesical doxorubicin. They were followed up by cystoscopy every 3 months for 2 years and every 6 months thereafter with special emphasis on recurrence rates. The study included 85 patients with non-invasive bladder tumours: 23 with non-invasive papillary carcinoma (Stage Ta), 62 with tumour invading subepithelial connective tissue (Stage T1). Twelve patients had well differentiated tumours (Grade 1), 48 had moderately differentiated (Grade 2), 25 had poorly differentiated (Grade 3) tumours. The total recurrence rate was 23%. The rates of recurrence were 56% in Grade 3 and 0% in Grade 1. The recurrence rate was 41% in patients with large tumours versus 17% in those with small tumours; 44% in those with multiple tumours compared to 18% in those with solitary tumours; 30% of Stage Ta tumours recurred and 21% of Stage T1 tumours. In short term follow-up, our rate of recurrence was 23%. Adjuvant intravesical doxorubicin was shown to reduce the recurrence of superficial bladder cancer. Tumour grade, size and number were shown to be prognostic factors for recurrence.

To develop a nomogram based on postoperative factors and prostate-specific antigen levels to predict the non-biochemical recurrence rate after radical prostatectomy ina Japanese cohort. A total of 606 Japanese patients with T1-3N0M0 prostate cancer who underwent radical prostatectomy and pelvic lymph node dissection at Tokyo Medical University hospital from 2000 to 2010 were studied. A nomogram was constructed based on Cox hazard regression analysis evaluating the prognostic significance of serum prostate-specific antigen and pathological factors in the radical prostatectomy specimens. The discriminating ability of the nomogram was assessed by the concordance index (C-index), and the predicted and actual outcomes were compared with a bootstrapped calibration plot. With a mean follow up of 60.0 months, a total of 187 patients (30.9%) experienced biochemical recurrence, with a 5-year non-biochemical recurrence rate of 72.3%. Based on a Cox hazard regression model, a nomogram was constructed to predict non-biochemical recurrence using serum prostate-specific antigen level and pathological features in radical prostatectomy specimens. The concordance index was 0.77, and the calibration plots appeared to be accurate. The postoperative nomogram described here can provide valuable information regarding the need for adjuvant/salvage radiation or hormonal therapy in patients after radical prostatectomy.

The purpose of this study was to determine the safety and efficacy of adjuvant albendazole medication in percutaneous liver hydatid cyst treatment with puncture, aspiration, injection, and reaspiration (PAIR) method. Between November 2007 and May 2011, total of 39 patients with newly diagnosed liver hydatid cyst (total of 77 cysts) were prospectively randomized and enrolled in 3 groups. In the first group, cysts (n = 14) were treated with PAIR without albendazole. In the second (n = 16) and third groups (n = 47), cysts were treated with PAIR with albendazole 1 week before and 1 month after the procedure, with albendazole 1 week before and 3 months after the procedure respectively. Technical and clinical success rates were 100 and 96.1% respectively. In 3 of 77 cysts (3.9%), findings of recurrence were detected on US imaging. All recurrent cysts were in group 1 and recurrence rates in this group were statistically different from cysts of second and third groups (p = 0.005). Side effects of albendazole were detected in 7 of 29 patients (24.1%), and no statistically significant difference was observed between the second (15.3%) and third (38.4%) groups (p = 0.378). Use of albendazole medication as an adjuvant to percutaneous treatment of liver hydatid cyst decreases the recurrence rate. Although there is no statistically significant difference between groups 2 and 3 in terms of efficacy and recurrence rate, patients in group 3 had a higher rate of side effect. Therefore, we conclude that albendazole treatment 1 week before and 1 month after PAIR treatment is sufficient to reduce/prevent recurrences.

This study aimed to evaluate the impact of intra-operative neuromonitoring of the recurrent laryngeal nerve during total thyroidectomy for benign goitre. A single-centre retrospective study using historical controls was conducted for a 10-year period, comprising a series of 767 patients treated by total thyroidectomy for benign goitre. Of these, 306 had intra-operative neuromonitoring of the recurrent laryngeal nerve and 461 did not. Post-operative laryngeal mobility was assessed in all patients by direct laryngoscopy before hospital discharge and at post-operative follow-up visits. In all, 6 out of 461 patients (1.30 per cent) in the control group and 6 out of 306 patients (1.96 per cent) in the intra-operative neuromonitoring group developed permanent recurrent laryngeal nerve palsy. No statistically significant difference was observed between the two patient groups. Intra-operative neuromonitoring does not appear to affect the post-operative recurrent laryngeal nerve palsy rate or to reliably predict post-operative recurrent laryngeal nerve palsy. However, it can accurately predict good nerve function after thyroidectomy.

Benign multinodular goiter (BMNG) is the most common endocrine disease requiring surgery. During the last few years a more aggressive approach has become the trend for bilateral BMNG treatment. Randomized clinical trials of any size that compared bilateral subtotal resection, Dunhill procedure and total thyroidectomy for benign multinodular goiter, published between January 2000 and the end of March 2015, were reviewed. Total thyroidectomy can be considered the most reliable approach in preventing recurrence. The Dunhill procedure is related to a higher rate of recurrence, but rarely recurrences after Dunhill procedure lead to reoperation. Total thyroidectomy avoid completion thyroidectomy for incidental carcinoma and its related risks. Recurrent laryngeal nerve (RLN) palsy becomes less common as surgical experience increases. Transient and permanent hypoparathyroidism is strictly related to the extent of neck dissection. In the risk-cost analysis we must consider the type of patient candidated to surgery and the impact of the surgical protocol we apply. When thyroid surgery is taken in consideration, specific complication rates of different procedures in each hospital must be analyzed accordingly to patient-specific risk factors and local expertise. The Dunhill procedure seems to be a good compromise between radicality and prevention of complications, avoiding reoperation for recurrence or completion thyroidectomy for incidental thyroid carcinoma. More follow-up studies and prospective studies are necessary to better evaluate, definitively, whether to prefer total thyroidectomy or Dunhill procedure in case of benign goiter surgery.

Background  Conflicting data exist with regard to recurrence rates of intestinal metaplasia (IM) and dysplasia after achieving complete eradication of intestinal metaplasia (CE-IM) in Barrett’s esophagus (BE) patients. Aim  (i) To determine the incidence of recurrent IM and dysplasia achieving CE-IM and (ii) to compare recurrence rates between treatment modalities [radiofrequency ablation (RFA) with or without endoscopic mucosal resection (EMR) vs stepwise complete EMR (SRER)]. Methods  A systematic search was performed for studies reporting on outcomes and estimates of recurrence rates after achieving CE-IM. Pooled incidence [per 100-patient-years (PY)] and risk ratios with 95 %CI were obtained. Heterogeneity was measured using the I 2 statistic. Subgroup analyses, decided a priori, were performed to explore heterogeneity in results. Results  A total of 39 studies were identified (25-RFA, 13-SRER, and 2 combined). The pooled incidence of any recurrence was 7.5 (95 %CI 6.1 – 9.0)/100 PY with a pooled incidence of IM recurrence rate of 4.8 (95 %CI 3.8 – 5.9)/100 PY, and dysplasia recurrence rate of 2.0 (95 %CI 1.5 – 2.5)/100 PY. Compared to the SRER group, the RFA group had significantly higher overall [8.6 (6.7 – 10.5)/100 PY vs. 5.1 (3.1 – 7)/100 PY, P  = 0.01] and IM recurrence rates [5.8 (4.3 – 7.3)/100 PY vs. 3.1 (1.7 – 4)/100 PY, P  < 0.01] with no difference in recurrence rates of dysplasia. Significant heterogeneity between studies was identified. The majority of recurrences were amenable to repeat endoscopic eradication therapy (EET). Conclusion  The results of this study demonstrate that the incidence rates of overall, IM, and dysplasia recurrence rates post-EET are not inconsiderable and reinforce the importance of close surveillance after achieving CE-IM.

Background The objective of this study was to determine the rate and pattern of nodal recurrence in patients who underwent a therapeutic, lateral neck dissection (LND) for papillary thyroid cancer (PTC) with clinically evident cervical metastases and to determine if there was any correlation between the extent of initial dissection and the rate and pattern of neck recurrence. Methods A total of 3,664 patients with PTC treated between 1986 and 2010 at Memorial Sloan Kettering Cancer Center were identified from our institutional database. Tumor factors, patient demographics, extent of initial LND, and adjuvant therapy were recorded. Patterns of recurrent lateral neck metastases by level involvement were recorded and outcomes calculated using the Kaplan-Meier method. Results A total of 484 patients had an LND for cervical metastases; 364 (75%) had a comprehensive LND (CLND) and 120 (25%) had a selective neck dissection (SND). The median duration of follow-up was 63.5 months. As expected, patients with CLND had a greater number of nodes removed as well as a greater number of positive nodes (P < .001). There was no difference in overall lateral neck recurrence-free status (CLND 94.4% vs SND 89.4%, P = .158), but in the dissected neck, the ipsilateral lateral neck recurrence-free status was superior in the CLND patients (97.7% vs 89.4%, P < .001). Conclusion Patients with clinically evident neck metastases from PTC managed by CLND have lesser rates of recurrence in the dissected neck compared with patients managed by SND. SND should only be done in highly selected cases with small volume disease. PMID:26994486

The rate and risk factors for recurrence of anaphylaxis are not well known. To measure the rate and risk factors for recurrent anaphylaxis in a population-based cohort in Olmsted County, Minnesota. We conducted a population-based cohort study using the Rochester Epidemiology Project, a comprehensive medical records linkage system, to obtain records of patients who presented to medical centers within the Olmsted County area with anaphylaxis from January 1, 2001, through December 31, 2010. We evaluated the rate and associations of risk factors with anaphylaxis recurrence. Among the 611 patients with anaphylaxis, 50 (8%) experienced a total of 60 recurrences within the 10-year period, resulting in a recurrence rate of 2.6 per 100 person-years. A history of atopic dermatitis (hazard ratio [HR], 5.6; 95% confidence interval [CI], 2.0-16.1; P = .001), presenting symptoms of cough (HR, 4.7; 95% CI, 2.1-10.7; P < .001) oral pruritus (HR, 9.9; 95% CI, 4.3-23.2; P < .001), and receiving corticosteroids (HR, 5.2; 95% CI, 2.3-11.7; P < .001) were associated with an increased risk of recurrence. The cardiovascular symptom of chest pain (HR, 0.24; 95% CI, 0.07-0.79; P = .02) was associated with a decreased risk of recurrence. In this epidemiologic study, the rate of recurrence was 8% during the 10-year study period (recurrence rate of 2.6 per 100 person-years). Those with atopic dermatitis and mucocutaneous or respiratory symptoms were more likely to have a recurrent anaphylactic event. Our findings underscore the importance of early patient access to self-injectable epinephrine and referral to an allergist/immunologist for additional testing and education.

To review surgical-site infection (SSI) and retrieval-site tumor recurrence rates in laparoscopic colorectal procedures when using a plastic freezer bag as a wound protector. Laparoscopic colorectal procedures where a plastic freezer bag used as a wound protector at the extraction site were reviewed between 1991 and 2008 from a prospectively collected database. χ test was used to compare SSI and tumor recurrence rates between groups. Costing data were obtained from the operating room supplies department. A total of 936 cases with 51 (5.45%) surgical-site infections were identified. SSI rates did not differ when comparing groups based on demographic factors, diagnosis, or location of procedure. Retrieval-site tumor recurrence rate was 0.21% (1/474). Cost of plastic freezer bags including sterilization ranged from $0.25 to $3. Plastic freezer bags as wound protectors in laparoscopic colorectal procedures are cost effective and have SSI and retrieval-site tumor recurrence rates that compare favorably to published data.

To examine the trends of new and recurrent sports-related concussions in high-school athletes before and after youth sports traumatic brain injury laws. We used an interrupted time-series design and analyzed the concussion data (2005-2016) from High School Reporting Injury Online. We examined the trends of new or recurrent concussion rates among US representative high-school athletes participating in 9 sports across prelaw, immediate-postlaw, and postlaw periods by using general linear models. We defined 1 athlete exposure as attending 1 competition or practice. We included a total of 8043 reported concussions (88.7% new, 11.3% recurrent). The average annual concussion rate was 39.8 per 100 000 athlete exposures. We observed significantly increased trends of reported new and recurrent concussions from the prelaw, through immediate-postlaw, into the postlaw period. However, the recurrent concussion rate showed a significant decline 2.6 years after the laws went into effect. Football exhibited different trends compared with other boys' sports and girls' sports. Observed trends of increased concussion rates are likely attributable to increased identification and reporting. Additional research is needed to evaluate intended long-term impact of traumatic brain injury laws.

To investigate the relationship between the operative approach, clinical pathological factors, and curative effect of the surgical treatment in the patients with craniopharyngioma; to provide a theoretical basis for determining the prognosis and reducing the recurrence rate during the long-term postoperative follow-up in children. This was a retrospective analysis of the clinical data of 92 children who underwent surgical treatment in our department from May 2011 to January 2005. Long-term follow-up was performed from 12 months to 8 years. The pterional approach was used in 49 patients, the interhemispheric approach in 20 patients, the corpus callosum approach in 16 patients, and the butterfly approach in 7 patients. Pathological classification was performed by hematoxylin and eosin stain staining of the pathological tissues and evaluated according to the different surgical approaches, MRI calcification status, calcification type, pathological type, whether radiotherapy was performed, postoperative recurrence, and death. For the pterion approach resection, there was near total resection in 46 patients (93.9%) with the lowest recurrence rate. The operative approach and postoperative recurrence rates were compared; the difference was statistically significant (P <0.05). For comparison of the operative approach and postoperative mortality, the difference was not statistically significant (P >0.05). There was not a significant difference between the MRI classification and postoperative recurrence rate (P >0.05). Comparing the degree of tumor calcification with the recurrence rate after operation and the mortality rate, the difference was statistically significant (P <0.05). The recurrence rate and mortality rate of adamantimous craniopharyngioma and squamous papillary craniopharyngioma in 2 groups following operation were compared, and the differences were statistically significant (P <0.05). Postoperative adjuvant radiotherapy was compared with the postoperative recurrence rate and mortality; the differences were statistically significant (P <0.05). The main effects on tumor recurrence include the choice of surgical approach and degree of calcification. The adamantimous craniopharyngioma relapse rate is higher, which could be because invasion of craniopharyngioma only occurs with adamantimous craniopharyngioma. Postoperative radiotherapy can significantly prolong the recurrence time and reduce the mortality rate of patients with craniopharyngioma.

To determine whether different treatment approaches of ectopic pregnancy (EP), particularly unilateral salpingectomy and methotrexate, affect its recurrence rate in patients undergoing in vitro fertilization (IVF). A retrospective cohort study (Canadian Task Force classification II-2). An academic medical center. Patients with a history of a previous EP who achieved pregnancy after IVF cycles between January 2004 and August 2015 were included. The recurrence rate of EP was compared between patients who underwent different treatment approaches for a previous EP. IVF. A total of 594 patients were included. Seventeen patients had a recurrence of EP (2.9%). Patients with a history of ≥2 EPs were associated with a significantly higher recurrence rate of EP than those with 1 previous EP (8.5% vs. 1.8%; p = .01; odds ratio [OR] = 2.2; 95% confidence interval [CI], 1.2-4.4). Patients who underwent unilateral salpingectomy (n = 245) had a comparable recurrence rate of EP after IVF with those who received methotrexate (n = 283) (3.6% vs. 2.8%; p = .5; OR = 1.3; 95% CI, 0.4-3.4). This OR remained unchanged after adjusting for patient's age, number of previous EPs, number of transferred embryos, and peak estradiol level during stimulation (adjusted OR = 1.4; 95% CI, 0.5-3.8). None of the patients who underwent bilateral salpingectomy (n = 45) or salpingostomy (n = 21) had a recurrence of EP after IVF. The recurrence rate of EP significantly correlates with the number of previous EPs. Treatment of EP with methotrexate has a comparable recurrence rate of EP after IVF with unilateral salpingectomy. Therefore, the risk of recurrence should not be a reason to favor salpingectomy over methotrexate in this population. Copyright © 2017 AAGL. Published by Elsevier Inc. All rights reserved.

It was the aim of this prospective study to evaluate the outcome of laparoscopic surgery for diverticular disease. All patients who underwent elective laparoscopic colectomy for diverticular disease within a 10-year period were prospectively entered into a PC database registry. Indications for laparoscopic surgery were acute complicated diverticulitis (Hinchey stages I and IIa), chronically recurrent diverticulitis, sigmoid stenosis or outlet obstruction caused by chronic diverticulitis. Surgical procedures (sigmoid and anterior resection, left colectomy and resection rectopexy) included intracorporeal dissection and colorectal anastomosis. Parameters studied included age, gender, stage of disease, procedure, duration of surgery, intraoperative technical variables, transfusion requirements, conversion rate, total complication rate including major (requiring re-operation), minor (conservative treatment) and late-onset (post-discharge) complication rates, stay on ICU, hospitalisation, mortality, and recurrence. For objective evaluation, only laparoscopically completed procedures were analysed. Comparative outcome analysis was performed with respect to stage of disease and experience. A total of 396 patients underwent laparoscopic colectomy. Conversion rate was 6.8% ( n=27), so that laparoscopic completion rate was 93.2% ( n=369). Most common reasons for conversion were directly related to the inflammatory process, abscess or fistulas. The most common procedure was sigmoid resection ( n=279), followed by anterior resection ( n=36) and left colectomy ( n=29). Total complication rate was 18.4% ( n=68). Major complication rate was 7.6% ( n=28), whereas the most common complication requiring re-operation was haemorrhage in 3.3% ( n=12). Anastomotic leakage occurred in 1.6% ( n=6). Minor complications were noted in 10.7% ( n=40), late-onset complications occurred in 2.7% ( n=10). Mortality was 0.5% ( n=2). Mean duration of surgery was 193 (range 75-400) min, return to normal diet was completed after 6.8 (range 3-19) days. Mean hospital stay was 11.8 (range 4-71) days. No recurrence of diverticulitis occurred. Laparoscopic surgery for diverticular disease is safe, feasible and effective. Therefore, laparoscopic colectomy has replaced open resection as standard surgery for recurrent and complicated diverticulitis at our institution.

The objective of this study was to determine the rate and pattern of nodal recurrence in patients who underwent a therapeutic, lateral neck dissection (LND) for papillary thyroid cancer (PTC) with clinically evident cervical metastases and to determine if there was any correlation between the extent of initial dissection and the rate and pattern of neck recurrence. A total of 3,664 patients with PTC treated between 1986 and 2010 at Memorial Sloan Kettering Cancer Center were identified from our institutional database. Tumor factors, patient demographics, extent of initial LND, and adjuvant therapy were recorded. Patterns of recurrent lateral neck metastases by level involvement were recorded and outcomes calculated using the Kaplan-Meier method. A total of 484 patients had an LND for cervical metastases; 364 (75%) had a comprehensive LND (CLND) and 120 (25%) had a selective neck dissection (SND). The median duration of follow-up was 63.5 months. As expected, patients with CLND had a greater number of nodes removed as well as a greater number of positive nodes (P < .001). There was no difference in overall lateral neck recurrence-free status (CLND 94.4% vs SND 89.4%, P = .158), but in the dissected neck, the ipsilateral lateral neck recurrence-free status was superior in the CLND patients (97.7% vs 89.4%, P < .001). Patients with clinically evident neck metastases from PTC managed by CLND have lesser rates of recurrence in the dissected neck compared with patients managed by SND. SND should only be done in highly selected cases with small volume disease. Copyright © 2016 Elsevier Inc. All rights reserved.

The gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (MRI) often depicts non-hypervascular hypointense hepatic nodules during the hepatobiliary phase in patients with hepatocellular carcinoma (HCC). It is unclear whether the presence of these nodules is associated with HCC recurrence after hepatectomy. We conducted a prospective observational study to investigate the impact of the presence of non-hypervascular hypointense hepatic nodules on the hepatobiliary phase of Gd-EOB-DTPA-enhanced MRI on the recurrence of HCC after hepatectomy. A total of 77 patients who underwent hepatectomy for primary, non-recurrent, hypervascular HCC were prospectively followed up after hepatectomy. Post-operative recurrence rates were compared according to the presence of non-hypervascular hypointense nodules on preoperative Gd-EOB-DTPA-enhanced MRI. Recurrence rates after hepatectomy were higher in patients with non-hypervascular hypointense nodules (risk ratio 1.9396 [1.3615-2.7222]) and the presence of non-hypervascular hypointense nodules was an independent factor associated with postoperative recurrence (risk ratio 2.1767 [1.5089-3.1105]) along with HCC differentiation and portal vein invasion. While no differences were found in the rate of intrahepatic metastasis recurrence based on the preoperative presence of non-hypervascular hypointense hepatic nodules, the rate of multicentric recurrence was significantly higher in patients with preoperative non-hypervascular hypointense hepatic nodules. Patients with preoperative non-hypervascular hypointense hepatic nodules detected during the hepatobiliary phase of Gd-EOB-DTPA-enhanced MRI are at higher risk of HCC recurrence after hepatectomy, mainly due to multicentric recurrence.

Preoperative radiotherapy combined with total mesorectal excision (TME) has provided excellent local control in the treatment of rectal cancer. This study is a review of patients treated at our regional cancer center from 1998 to 2004. The results were compared with a similar study carried out in our region from 1988 to 1998 to determine any changes in treatment methods, recurrence rates, and survival. A retrospective review of 448 patients treated with definitive surgery for rectal cancer was conducted. Patient factors analyzed included sex, age, type of surgery, and adjuvant strategy. Tumor factors analyzed included level, stage, and grade. The presence of local recurrence was recorded and overall survival was determined. The local recurrence rate was 8.3% compared with 12.7% in the previous study. Patients treated with preoperative radiotherapy had a recurrence rate of 3.7%. The type of surgical therapy had no significant effect on local recurrence. There was no significant change in overall survival between the present study and the previous one. Preoperative radiotherapy is used more frequently in our region and has resulted in a decrease in the local recurrence rate compared to our previous retrospective review. There was no change in local recurrence seen in those patients treated with operative management alone. This study supports the use of preoperative radiotherapy in the management of rectal cancer.

We investigated sex-hormone receptor expression as predicting factor of recurrence and progression in patients with non-muscle invasive bladder cancer. We retrospectively evaluated tumor specimens from patients treated for transitional cell carcinoma of the bladder at our institution between January 2006 and January 2011. Performing immunohistochemistry using a monoclonal androgen receptor antibody and monoclonal estrogen receptor-beta antibody on paraffin-embedded tissue sections, we assessed the relationship of immunohistochemistry results and prognostic factors such as recurrence and progression. A total of 169 patients with bladder cancer were evaluated in this study. Sixty-threepatients had expressed androgen receptors and 52 patients had estrogen receptor beta. On univariable analysis, androgen receptor expression was significant lower in recurrence rates (p=0.001), and estrogen receptor beta expression was significant higher in progression rates (p=0.004). On multivariable analysis, significant association was found between androgen receptor expression and lower recurrence rates (hazard ratio=0.500; 95% confidence interval, 0.294 to 0.852; p=0.011), but estrogen receptor beta expression was not significantly associated with progression rates. We concluded that the possibility of recurrence was low when the androgen receptor was expressed in the bladder cancer specimen and it could be the predicting factor of the stage, number of tumors, carcinoma in situ lesion and recurrence.

Objective: To explore the causes and countermeasure in recurrent bleeding following the selective renal artery embolization treating post-percutaneous nephrolithotomy hemorrhage. Methods: A total of 334 patients of severe renal hemorrhage associated with percutaneous nephrolithotomy (PCNL) from March 2011 to April 2015 were analyzed retrospectively.All the patients underwent super selective angiography and renal artery embolization.The causes of recurrent hemorrhage were analyzed and principles for diagnosis and embolization were studied. Results: The initial embolization was performed in 329 cases hospitalized in the First Affiliated Hospital of Guangzhou Medical University and 318 cases were successfully stopped bleeding with a hemostatic rate of 96.7 %(318/329). Of total 334 consecutive cases, there were 16 cases of recurrent renal hemorrhage, 11 cases were initially embolized in this hospital, and otherwise the other 5 cases were in other hospitals. Causes of recurrent hemorrhage were missed embolization of tiny pseudoaneurysm ( n =12), and two cases of 12, the tiny pseudoaneurysm were feeding by accessory renal arteries, undetected arteriovenous fistula( n =2), recanalization of the embolized arteries ( n =2). Conclusion: The causes of recurrent bleeding fallowing the initial selective renal artery embolization treating post-percutaneous nephrolithotomy hemorrhage are varied, and missed embolization of tiny pseudoaneurysm is the major cause of unsuccessful initial renal artery embolization. To strengthen the understanding of tiny pseudoaneurysm is helpful to improve the success rate of hemostasis.

To evaluate graft stability and recurrence rate between fibrin glue and autologous blood in pterygium conjunctival autograft surgery. A prospective, randomized, single-blinded clinical trial to assess the efficacy of autologous blood in place of fibrin glue in pterygium surgery. A total of 120 eyes of 111 patients were randomized according to pterygium morphology, to undergo pterygium surgery with autografting using either autologous blood or fibrin glue. All patients were operated by a single surgeon; 58 eyes were operated using fibrin glue and 62 eyes had a conjunctival autograft with autologous blood. Patients were seen on postoperative day 1, 1 week, 1 month, 6 months, and 1 year after surgery. Graft stability and pterygium recurrence were graded by an independent observer who was masked to the method of treatment. All 120 eyes completed the 1-year follow-up. Graft loss was seen only in the autologous blood group. Of the 62 eyes in this group, a total of 15 (24.2%) grafts dislodged. Recurrence was calculated after excluding grafts that were dislodged. Of the 105 patients, there were a total of 7 recurrences, 2 (3.4%) from the fibrin adhesive method and 5 (10.6%) from the autologous blood method. This was not statistically significant (P = 0.238). Autologous blood does not exhibit similar graft stability seen with fibrin glue. Although the recurrence rate may not be significant, careful patient selection and a standard method needs to be laid out before the use of this method is widely accepted.

Objective To determine the incidence and impact of recurrent workplace injury and disease over the period 1995–2008. Design Population-based cohort study using data from the state workers’ compensation system database. Setting State of Victoria, Australia. Participants A total of 448 868 workers with an accepted workers’ compensation claim between 1 January 1995 and 31 December 2008 were included into this study. Of them, 135 349 had at least one subsequent claim accepted for a recurrent injury or disease during this period. Main outcome measures Incidence of initial and recurrent injury and disease claims and time lost from work for initial and recurrent injury and disease. Results Over the study period, 448 868 workers lodged 972 281 claims for discrete occurrences of work-related injury or disease. 53.4% of these claims were for recurrent injury or disease. On average, the rates of initial claims dropped by 5.6%, 95% CI (−5.8% to −5.7%) per annum, while the rates of recurrent injuries decreased by 4.1%, 95% CI (−4.2% to −0.4%). In total, workplace injury and disease resulted in 188 978 years of loss in full-time work, with 104 556 of them being for the recurrent injury. Conclusions Recurrent work-related injury and disease is associated with a substantial social and economic impact. There is an opportunity to reduce the social, health and economic burden of workplace injury by enacting secondary prevention programmes targeted at workers who have incurred an initial occupational injury or disease.

Management of pressure sores poses a significant reconstructive challenge for plastic surgeons. Currently, there is no consensus on whether musculocutaneous, fasciocutaneous, or perforator-based flaps provide superior results for treating pressure sores. The following databases were searched: Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, LILACS (January of 1950 to November of 2010), MEDLINE (January of 1950 to November of 2010), and EMBASE (January of 1980 to November of 2010). Only articles reporting on the use of musculocutaneous, fasciocutaneous, and perforator-based flaps were included. The primary study outcomes were complication and recurrence rates. Fifty-five articles were included in the final analysis (kappa = 0.78). From this total, 28 were categorized as pertaining to musculocutaneous flaps, 13 studied fasciocutaneous flaps, and 14 evaluated perforator-based flaps. The authors' review revealed recurrence and complication rates of 8.9 and 18.6 percent, respectively, following reconstruction with musculocutaneous flaps, 11.2 and 11.7 percent following reconstruction with fasciocutaneous flaps, and 5.6 and 19.6 percent following reconstruction with perforator-based flaps. Overall, statistical analysis revealed no significant difference in complication or recurrence rates among these three techniques. The authors' review revealed that there was no statistically significant difference with regard to recurrence or complication rates among musculocutaneous, fasciocutaneous, or perforator-based flaps. This suggests that surgeons performing such reconstructive procedures may choose to consider the advantages of a specific approach rather than the complication and recurrence rates. Therapeutic, IV.

To describe patients developing grade III and IV hemorrhoids requiring surgery after laparoscopic ventral mesh rectopexy (LVMR) and to explore the relationship between developing such hemorrhoids and recurrence of rectal prolapse after LVMR. All consecutive patients receiving LVMR at the Meander Medical Centre, Amersfoort, the Netherlands, between 2004 and 2013 were analyzed. Kaplan-Meier estimates were calculated for recurrences. A total of 420 patients underwent LVMR. Sixty-five of these patients (actuarial 5-year incidence 24.3, 95 % confidence interval (CI) 18.6-30.0) developed symptomatic grade III/IV hemorrhoids requiring stapled or excisional hemorrhoidectomy. Re-do surgery for recurrent grade III/IV hemorrhoids was required for 15 of the 65 patients (actuarial 5-year recurrence rate 40.6, 95 % CI 23.2-58.0) after the primary hemorrhoidectomy. Three of the 65 patients developed an external rectal prolapse (ERP) recurrence and eight an internal rectal prolapse (IRP) recurrence. This generated a 5-year recurrence rate of 25.3 % (95 % CI 0-53.9) for ERP recurrence and 24.4 % (95 % CI 9.1-39.7) for IRP recurrence. The rest of the LVMR cohort not receiving additional surgery for hemorrhoids (n = 355) showed significantly lower actuarial 5-year ERP (0.8 %, p = 0.011) and IRP (11 %, p = 0.020) recurrence rates. High-grade hemorrhoids requiring surgery may be common after LVMR. The development of high-grade hemorrhoids after LVMR might be considered a predictor of rectal prolapse recurrence.

Purpose: In the years 1993–1996 a number of presumably false-positive breast cancer diagnoses were made by a pathologist in Essen. A follow-up, undertaken 15 years later, investigated how many women had tumour recurrence and/or metastasis or had died from breast cancer. Material and Methods: A total of 151 (68 %) out of 222 women could be traced. One hundred and forty-seven (66.2 %) of the 222 women were alive. The observed survival rate, number of recurrences and/or metastases, and number of deaths from breast cancer were compared with data from the Munich Tumour Registry. The number of breast cancer cases among daughters of the affected women was ascertained. Results: The total observed survival rate at follow-up after 15 years was 93 %, a much higher figure than the survival rate of 45 % given by the Munich Tumour Registry. Recurrence and/or metastasis or death from breast cancer occurred in 9/222 cases (4.1 %). The incidence for these events calculated according to data from the Munich Tumour Registry is 13 %. Two daughters (2.2 %) out of a total of 90 were diagnosed with breast cancer whereas, according to the German Cancer Research Centre, the expected rate would have been between 5 and 10 %. Conclusions: The results of our follow-up after 15 years show that more women survived than expected and that the number of recurrences and/or metastases and deaths due to breast cancer was lower than expected. Fewer daughters of affected women were diagnosed with breast cancer than expected. These results support our suspicion that not all women diagnosed with breast cancer by a pathologist in Essen actually had breast cancer. PMID:25284840

There are no data on the efficacy of secondary prophylaxis against Pneumocystis pneumonia after solid organ transplantation. Therefore, we investigated the rate of recurrence of Pneumocystis pneumonia after solid organ transplantation in a retrospective cohort study. Between 2005 and 2011, a total of 41 recipients recovered from Pneumocystis pneumonia. Of these, 22 (53.7%) received secondary prophylaxis. None of the 41 recipients experienced recurrence of Pneumocystis pneumonia during the follow-up, regardless of secondary prophylaxis.

To investigate the interactions between splenectomy and perioperative transfusion in gastric cancer patients. Medical records of 449 gastric cancer patients who had undergone total gastrectomies for curative intent between 1991 and 1995 were reviewed. The influence of splenectomy on tumor recurrence and survival both in the transfused and nontransfused patients were evaluated by univariate and multivariate analysis. The recurrence rate in the splenectomy group was 48.1% as compared with 22.6% in the spleen-preserved group among transfused patients (P=.001); it was 40.7% compared with 26.5% among nontransfused patients (P=.086). There was no significant difference in the mean survival between the splenectomy group and the spleen-preserved group in a subgroup analysis by stage. Multivariate analysis identified splenectomy as an independent risk factor for recurrence but not as a predictor for survival among transfused patients. Splenectomy does not appear to abrogate the adverse effect of perioperative transfusion on prognosis in gastric cancer patients. Moreover, it may increase postoperative recurrence in transfused patients.

Soft tissue sarcomas (STS) are a rare entity with reduced prognosis due to their aggressive biology. For an optimal treatment of STS identification of independent prognostic factors is crucial in order to reduce tumor-related mortality and recurrence rates. The surgical oncological concept includes wide excisions with resection safety margins >1 cm which enables acceptable functional results and reduced rates of amputation of the lower extremities. In contrast, individual anatomy of the upper extremities, in particular of the hand, leads to an intentional reduction of resection margins in order to preserve the extremity and its function with the main intention of tumor-free resection margins. In this study, the oncological safety and outcome as well as functional results were validated by a retrospective analysis of survival rate, recurrence rate and potential prognostic factors. A total of 160 patients who had been treated for STS of the upper extremities were retrospectively included. Independent prognostic factors were analyzed (primary versus recurrent tumor, tumor size, resection status, grade of malignancy, additional therapy, localization in the upper extremity). Kaplan-Meier analyses for survival rate and local control were calculated. Further outcome measures were functional results validated by the DASH score and rate of amputation. In 130 patients (81%) wide tumor excision (R0) was performed and in 19 patients (12%) an amputation was necessary. The 5-year overall survival rate was 70% and the 5-year survival rate in primary tumors was 81% whereas in recurrences 55% relapsed locally. The 10-year overall survival rate was 45% and the 5-year recurrence rate was 18% for primary STS and 43% for recurrent STS. Variance analysis revealed primary versus recurrent tumor, tumor size, resection status and grade of malignancy as independent prognostic factors. Analysis of functional results showed a median DASH score of 37 (0-100; 0=contralateral extremity). The 5-year survival and local recurrence rates are comparable to STS wide resections with safety margins >1 cm for the lower extremities and the trunk. Analysis of prognostic factors revealed resection status and the tumor-free resection margins to be the main goals in STS resection of upper extremity.

Considerable inter-observer variability in the visual assessment of aneurysm recurrences limits its use as an outcome parameter evaluating new coil generations. The purpose of this study was to compare visual assessment of aneurysm recurrences and aneurysm recurrence volumetry with an example dataset of HydroSoft coils (HSC) versus bare platinum coils (BPC). For this retrospective study, 3-dimensional time-of-flight magnetic resonance angiography datasets acquired 6 and 12 months after endovascular therapy using BPC only or mainly HSC were analyzed. Aneurysm recurrence volumes were visually rated by two observersas well as quantified by subtraction of the datasets after intensity-based rigid registration. A total of 297 aneurysms were analyzed (BPC: 169, HSC: 128). Recurrences were detected by aneurysm recurrence volumetry in 9 of 128 (7.0 %) treated with HSC and in 24 of 169 (14.2 %) treated with BPC (odds ratio: 2.39, 95 % confidence interval: 1.05-5.48; P = 0.039). Aneurysm recurrence volumetry revealed an excellent correlation between observers (Cronbach's alpha = 0.93). In contrast, no significant difference in aneurysm recurrence was found for visual assessment (3.9 % in HSC cases and 4.7 % in BPC cases). Recurrences were observed in aneurysms smaller than the sample median in 10 of 33 (30.3 %) by aneurysm recurrence volumetry and in 1 of 13 (7.7 %) by visual assessment. Aneurysm recurrences were detected more frequently by aneurysm recurrence volumetry when compared with visual assessment. By using aneurysm recurrence volumetry, differences between treatment groups were detected with higher sensitivity and inter-observer validity probably because of the higher detection rate of recurrences in small aneurysms.

Repair for a small (≤ 2 cm) umbilical and epigastric hernia is a minor surgical procedure. The most common surgical repair techniques are a sutured repair or a repair with mesh reinforcement. However, the optimal repair technique with regard to risk of reoperation for recurrence is not well documented. The aim of the present study was in a nationwide setup to investigate the reoperation rate for recurrence after small open umbilical and epigastric hernia repairs using either sutured or mesh repair. This was a prospective cohort study based on intraoperative registrations from the Danish Ventral Hernia Database (DVHD) of patients undergoing elective open mesh and sutured repair for small (≤ 2 cm) umbilical and epigastric hernias. Patients were included during a 4-year study period. A complete follow-up was obtained by combining intraoperative data from the DVHD with data from the Danish National Patient Register. The cumulative reoperation rates were obtained using cumulative incidence plot and compared with the log rank test. In total, 4,786 small (≤ 2 cm) elective open umbilical and epigastric hernia repairs were included. Age was median 48 years (range 18-95 years). Follow-up was 21 months (range 0-47 months). The cumulated reoperation rates for recurrence were 2.2 % for mesh reinforcement and 5.6 % for sutured repair (P = 0.001). The overall cumulated reoperation rate for sutured and mesh repairs was 4.8 %. In conclusion, reoperation rate for recurrence for small umbilical and epigastric hernias was significantly lower after mesh repair compared with sutured repair. Mesh reinforcement should be routine in even small umbilical or epigastric hernias to lower the risk of reoperation for recurrence avoid recurrence.

In Crohn's disease (CD), studies associating phenotype at diagnosis and subsequent disease activity are important for patient counselling and health care planning. To calculate disease recurrence rates and to correlate these with phenotypic traits at diagnosis. A prospectively assembled uniformly diagnosed European population based inception cohort of CD patients was classified according to the Vienna classification for disease phenotype at diagnosis. Surgical and non-surgical recurrence rates throughout a 10 year follow up period were calculated. Multivariate analysis was performed to classify risk factors present at diagnosis for recurrent disease. A total of 358 were classified for phenotype at diagnosis, of whom 262 (73.2%) had a first recurrence and 113 patients (31.6%) a first surgical recurrence during the first 10 years after diagnosis. Patients with upper gastrointestinal disease at diagnosis had an excess risk of recurrence (hazard ratio 1.54 (95% confidence interval (CI) 1.13-2.10)) whereas age >/=40 years at diagnosis was protective (hazard ratio 0.82 (95% CI 0.70-0.97)). Colonic disease was a protective characteristic for resective surgery (hazard ratio 0.38 (95% CI 0.21-0.69)). More frequent resective surgical recurrences were reported from Copenhagen (hazard ratio 3.23 (95% CI 1.32-7.89)). A mild course of disease in terms of disease recurrence was observed in this European cohort. Phenotype at diagnosis had predictive value for disease recurrence with upper gastrointestinal disease being the most important positive predictor. A phenotypic North-South gradient in CD may be present, illustrated by higher surgery risks in some of the Northern European centres.

Increasing options to treat Dupuytren disease include percutaneous needle fasciotomy (PNF), a minimally invasive technique that has proven to be effective for the treatment of primary disease. However, its effect on recurrent disease is not clear. We studied 30 patients with recurrent Dupuytren disease in 40 fingers, with a mean follow-up of 4.4 years. Primary outcome measures were total passive extension deficit reduction and interval to a second recurrence, defined as an increase of more than 30° compared with the result at the end of the previous treatment. We noted complications. Total passive extension reduction was 76%. Percutaneous needle fasciotomy was especially effective for the metacarpophalangeal joint, with an average reduction of 93%, whereas the average reduction in the proximal interphalangeal joint was 57%. A total of 50% of patients did not develop a secondary recurrence during follow-up. The other 50% did, and we treated recurrence within an average of 1.4 years after PNF. By means of PNF, we postponed tertiary treatment an average of 2.9 years starting from the initial treatment for Dupuytren disease. We successfully treated all secondary recurrences by limited fasciectomy, according to patients' wishes. We noted no major adverse effects. Percutaneous needle fasciotomy can be applied effectively for recurrent disease; 50% of patients remain free of recurrence for a mean of 4.4 years. If a secondary recurrence occurs, it does so relatively early after treatment. Patients must therefore be willing to accept this uncertainty in the context of the advantages of PNF, such as fast recovery, low complication rate, and minimal invasiveness.

Only a few studies report the long-term outcomes following repair of pectus excavatum (PE) and pectus carinatum (PC). Predictors of recurrence after surgery are important in this group of young patients. The purpose of this study was to assess the short- and long-term outcomes of both PE and PC and identify factors associated with postoperative complications and pectus recurrence. This was a retrospective observational study that included all patients who underwent primary or recurrent repair of PC and PE in a regional thoracic centre over 20 years. Patients' demographics, type of surgery, complications and recurrence were recorded. Logistic regression analysis was performed to identify factors predictive of pectus recurrence. A total of 297 patients were included (262 men and 35 women). The mean age was 19.8 years (95% CI 19.3-20.5). A total of 169 patients had surgery for PE and 127 for PC. A total of 243 patients had a modified Ravitch procedure (166 without a bar) and 53 patients underwent the Nuss repair. The main postoperative complications were wound infection and bleeding or haematoma. The recurrence rate over the mean follow-up period of 8.6 years was 10%. In PE, patients treated with the Ravitch procedure with the bar experienced more complications. Univariate and multivariate analyses showed that PE patients who developed a complication had a significantly increased chance of recurrence. No risk factors were linked with recurrence of PC. Life-transforming pectus surgery can be performed with low morbidity and good long-term outcomes. Recurrence of PE deformity is associated with the development of postoperative complications. © The Author 2016.

Information concerning short-term results for laparoscopic extraperitoneal hernia repair is available, but long-term results remain poorly documented. The purpose of this non-randomized prospective study was to evaluate recurrence and chronic pain after hernia repair over a period longer than 10 years. From 1995 to 2004, all patients aged 30 years or more, manifesting with inguinal hernia, were included in our study. Patients aged 20 to 30 years presenting with bilateral hernia, recurrent hernia, or who were heavy workers were also included. Patients who had pelvic irradiation, strangulated hernia, prostatic cancer resection, or a contra-indication to general anaesthesia were excluded. Of 1096 hernia repairs performed, 248 patients were excluded and underwent open repair and 848 patients (77.4%) were included in our prospective study, which corresponded to 1000 laparoscopic hernia repairs. The sex ratio (male : female) was 5:8, and the average age was 56 years. Seven hundred and fifty-three hernias (75.3%) were first repairs, 247 (24.7%) were recurrent hernias, and 161 were bilateral hernias. There were no mortalities. The conversion rate was 1.1%, and the global postoperative morbidity rate was 10.3%. Average follow-up was 39 months in 92.2% of the patients. Hernia recurrence rate was 1.5%. Chronic pain occurred in 2.9%. During this follow-up, 22 contra-lateral hernias appeared in those patients who initially had unilateral hernia repair (3.2%). All of these contra-lateral hernias could be successfully treated using a laparoscopic total extraperitoneal approach. The long-term results of this study demonstrate that preperitoneal laparoscopic hernia repair is a safe technique with a very low recurrence rate and low prevalence of chronic pain.

Purpose: To describe the use of radiosurgery (RS) alone to the resection cavity after resection of brain metastases as an alternative to adjuvant whole-brain radiotherapy (WBRT). Methods and Materials: Sixty-two patients with 64 cavities were treated with linear accelerator-based RS alone to the resection cavity after surgical removal of brain metastases between March 2007 and August 2010. Fifty-two patients (81%) had a gross total resection. Median cavity volume was 8.5 cm{sup 3}. Forty-four patients (71%) had a single metastasis. Median marginal and maximum doses were 18 Gy and 20.4 Gy, respectively. Sixty-one cavities (95%) had gross tumor volume to planningmore » target volume expansion of {>=}1 mm. Results: Six-month and 1-year actuarial local recurrence rates were 14% and 22%, respectively, with a median follow-up period of 9.7 months. Six-month and 1-year actuarial distant brain recurrence, total intracranial recurrence, and freedom from WBRT rates were 31% and 51%, 41% and 63%, and 91% and 74%, respectively. The symptomatic cavity radiation necrosis rate was 8%, with 2 patients (3%) undergoing surgery. Of the 11 local failures, 8 were in-field, 1 was marginal, and 2 were both (defined as in-field if {>=}90% of recurrence within the prescription isodose and marginal if {>=}90% outside of the prescription isodose). Conclusions: The high rate of in-field cavity failure suggests that geographic misses with highly conformal RS are not a major contributor to local recurrence. The current dosing regimen derived from Radiation Therapy Oncology Group protocol 90-05 should be optimized in this patient population before any direct comparison with WBRT.« less

Context Pelvic region pressure sores often develop following spinal cord injury. Surgery is often necessary for long standing, large-sized pressure sores not responding to conservative treatment. Authors analyze their results of a 10-year period, and identify factors contributing to the reduction of the recurrence rate. Methods A total of 119 pressure sores were operated on 98 patients in two institutions during a 10-year period (1 January 2003 to 31 December 2012). The encountered perioperative complications are summarized, and the recurrence rate is analyzed with a patient follow-up questionnaire. Results We experienced 15 perioperative complications (12.6%). All complications were fully resolved by conservative treatment. Fifty-eight returned patient replies were processed. The average follow-up time after surgery was 5.2 years. The recurrence rate was 5.47%. Conclusion The strict adherence to surgical indications, full patient compliance, specialized pre- and post-operative patient care, our routinely used preferred surgical method, all contribute to a low post-operative complication rate, long-term flap survival, and an extended recurrence free period.

Autonomic nervous system regulates the behavior of cardiac and respiratory systems. Its assessment during the ventilator weaning can provide information about physio-pathological imbalances. This work proposes a non linear analysis of the complexity of the heart rate variability (HRV) and breathing duration (T(Tot)) applying recurrence plot (RP) and their interaction joint recurrence plot (JRP). A total of 131 patients on weaning trials from mechanical ventilation were analyzed: 92 patients with successful weaning (group S) and 39 patients that failed to maintain spontaneous breathing (group F). The results show that parameters as determinism (DET), average diagonal line length (L), and entropy (ENTR), are statistically significant with RP for T(Tot) series, but not with HRV. When comparing the groups with JRP, all parameters have been relevant. In all cases, mean values of recurrence quantification analysis are higher in the group S than in the group F. The main differences between groups were found on the diagonal and vertical structures of the joint recurrence plot.

The EINSTEIN-Extension trial (EINSTEIN-EXT) found that continued treatment with rivaroxaban for an additional 6 or 12 months (vs placebo) after 6-12 months of initial anticoagulation significantly reduced the risk of recurrent venous thromboembolism (VTE) with a small non-significant increased risk of major bleeding (none fatal or in critical site). This study aimed to compare total healthcare cost between rivaroxaban and placebo, based on the EINSTEIN-EXT event rates. Total healthcare cost was calculated as the sum of treatment and clinical event costs from a US managed care perspective. Treatment duration and event rates were obtained from the EINSTEIN-EXT study. Adjustment on treatment duration was made by assuming a 10% non-adherence rate. Drug costs were based on wholesale acquisition costs. Cost estimates for clinical events (i.e. recurrent deep vein thrombosis [DVT], recurrent pulmonary embolism, major bleeding, clinically relevant non-major bleeding) were determined from the literature. Results were examined over a ±20% range of each cost component and over 95% confidence intervals (CIs) of event rate differences in deterministic (one-way) and probabilistic sensitivity analyses (PSA). Total healthcare cost was $1,454 lower for rivaroxaban-treated (vs placebo-treated) patients in the base-case, with a lower clinical event cost fully offsetting drug cost. The cost savings of recurrent DVT alone (-$3,102) was greater than drug cost ($2,723). Total healthcare cost remained lower for rivaroxaban in the majority (73%) of PSA (cost difference [95% CI] = -$1,454 [-$2,396, $1,231]). This study was conducted over the 1-year observation period of the EINSTEIN-EXT trial, which limited "real-world" applicability and examination of long-term economic impact. Assumptions on drug and clinical event costs were US-based and, thus, not applicable to other healthcare systems. Total healthcare costs were estimated to be lower for patients continuing rivaroxaban therapy compared to those receiving placebo in VTE patients who had completed 6-12 months of VTE treatment.

Background The gastrografin (GG) challenge is a diagnostic and therapeutic tool used to treat patients with small bowel obstruction (SBO); however, long-term data on SBO recurrence after the GG challenge remain limited. We hypothesized that patients treated with GG would have the same long-term recurrence as those treated before the implementation of the GG challenge protocol. Methods Patients ≥18 years who were treated for SBO between July 2009 and December 2012 were identified. We excluded patients with contraindications to the GG challenge (i.e., signs of strangulation), patients having SBO within 6-wk of previous abdominal or pelvic surgery and patients with malignant SBO. All patients had been followed a minimum of 1 y or until death. Kaplan–Meier method and Cox regression models were used to describe the time-dependent outcomes. Results A total of 202 patients were identified of whom 114 (56%) received the challenge. Mean patients age was 66 y (range, 19–99 y) with 110 being female (54%). A total of 184 patients (91%) were followed minimum of 1 year or death (18 patients lost to follow-up). Median follow-up of living patients was 3 y (range, 1–5 y). During follow-up, 50 patients (25%) experienced SBO recurrences, and 24 (12%) had exploration for SBO recurrence. The 3-year cumulative rate of SBO recurrence in patients who received the GG was 30% (95% confidence interval [CI], 21%–42%) compared to 27% (95% CI, 18%–38%) for those who did not (P = 0.4). The 3-year cumulative rate of exploration for SBO recurrence in patients who received the GG was 15% (95% CI, 8%–26%) compared to 12 % (95% CI, 6%–22%) for those who did not (P = 0.6). Conclusions The GG challenge is a clinically useful tool in treating SBO patients with comparable long-term recurrence rates compared to traditional management of SBO. PMID:27083946

Recurrent tuberculosis is an important indicator of the effectiveness of tuberculosis control and can occur by relapse or exogenous reinfection. We conducted a retrospective cohort study on all bacteriologically confirmed tuberculosis cases that were successfully treated between 2000 and 2012 in Shanghai, an urban area with a high number but a low prevalence rate of tuberculosis cases and a low prevalence of HIV infection. Genotyping the Mycobacterium tuberculosis from clinical isolates was used to distinguish between relapse and reinfection. In total, 5.3% (710/13,417) of successfully treated cases had a recurrence, a rate of 7.55 (95% CI 7.01-8.13) episodes per 1000 person-years, more than 18 times the rate of tuberculosis in the general population. Patients who were male, age 30-59, retreatment cases, had cavitation, diabetes, drug-resistant or multidrug-resistant tuberculosis in their initial episode of tuberculosis, were at high risk for a recurrence. Among 141 recurrent cases that had paired isolates, 59 (41.8%) had different genotypes, indicating reinfection with a different strain. Patients who completed treatment were still at high risk of another episode of tuberculosis and exogenous reinfection contributed a significant proportion of the recurrent tuberculosis cases. Targeted control strategies are needed to prevent new tuberculosis infections in this setting. Copyright © 2017 Elsevier Ltd. All rights reserved.

The procedure for prolapse and haemorrhoids (PPH) is an effective surgical therapy for symptomatic haemorrhoids. Compared with haemorrhoidectomy, meta-analysis has shown PPH to be less painful, with higher patient satisfaction and a quicker return to work, but at the cost of higher prolapse recurrence rates. This is the first report describing predictors of prolapse recurrence after PPH. A cohort of patients with symptomatic haemorrhoids, treated with PPH in our hospital between 2002 and 2009, was retrospectively analysed. Multivariate analysis was performed to identify patient-related and perioperative predictors associated with persisting prolapse and prolapse recurrence. In total, 159 consecutively enrolled patients were analysed. Persistence and recurrence of prolapse was observed in 16% of the patients. Increased surgical experience showed a trend towards lower recurrence rates. Multivariate analysis identified female gender, long duration of PPH surgery and the absence of muscle tissue in the resected specimen as independent predictors of postoperative persistence of prolapse of haemorrhoids. The absence of prior treatment with rubber band ligation (RBL) as well as increased PPH experience at the hospital showed a trend towards a higher rate of prolapse recurrence. In order to reduce recurrence of prolapse, PPH should be performed by a surgeon with adequate PPH experience, patients should be treated with RBL prior to PPH and a resection of mucosa with underlying muscle fibres should be strived for. © 2011 The Authors.

Long-term outcomes data for hernia recurrence rates after abdominal wall reconstruction (AWR) with acellular dermal matrix (ADM) are lacking. The aim of this study was to assess the long-term durability of AWR using ADM. We studied patients who underwent AWR with ADM at a single center in 2005 to 2015 with a minimum follow-up of 36 months. Hernia recurrence was the primary end point and surgical site occurrence (SSO) was a secondary end point. The recurrence-free survival curves were estimated by Kaplan-Meier product limit method. Univariate and multivariable Cox proportional hazards regression models and logistic regression models were used to evaluate the associations of risk factors at surgery with subsequent risks for hernia recurrence and SSO, respectively. A total of 512 patients underwent AWR with ADM. After excluding those with follow-up less than 36 months, 191 patients were included, with a median follow-up of 52.9 months (range 36 to 104 months). Twenty-six of 191 patients had a hernia recurrence documented in the study. The cumulative recurrence rates were 11.5% at 3 years and 14.6% by 5 years. Factors significantly predictive of hernia recurrence developing included bridged repair, wound skin dehiscence, use of human cadaveric ADM, and coronary disease; component separation was protective. In a subset analysis excluding bridged repairs and human cadaveric ADM patients, cumulative hernia recurrence rates were 6.4% by 3 years and 8.3% by 5 years. The crude rate of SSO was 25.1% (48 of 191). Factors significantly predictive of the incidence of SSO included at least 1 comorbidity, BMI ≥30 kg/m 2 , and defect width >15 cm. Use of ADM for AWR was associated with 11.5% and 14.6% hernia recurrence rates at 3- and 5-years follow-up, respectively. Avoiding bridged repairs and human cadaveric ADM can improve long-term AWR outcomes using ADM. Copyright © 2016 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

To evaluate the patterns, the risk factors, and the management of recurrence following brachytherapy in patients with posterior uveal melanoma, given that an understanding of the recurrence patterns can improve early recognition and management of local treatment failure in such patients. Retrospective cohort study. Setting: Multispecialty tertiary care center. A total of 375 eyes treated with episcleral brachytherapy for posterior uveal melanoma from January 2004 to December 2014. Exclusion criteria included inadequate follow-up (<1 year) and previous radiation therapy. Main Outcomes and Measures: Local control rate and time to recurrence were the primary endpoints. Kaplan-Meier estimation and Cox proportional hazards models were conducted to identify risk factors for recurrence. Twenty-one patients (5.6%) experienced recurrence (follow-up range 12-156 months; median 47 months). The median time to recurrence was 18 months (range 4-156 months). Five-year estimated local recurrence rate was 6.6%. The majority (90.5%) of the recurrences occurred within the first 5 years. The predominant site of recurrence was at the tumor margin (12 patients, 57.1%). Univariate analysis identified 3 statistically significant recurrence risk factors: advanced age, largest basal diameter, and the use of adjuvant transpupillary thermotherapy (TTT). Recurrent tumors were managed by repeat brachytherapy, TTT, or enucleation. Local recurrences following brachytherapy are uncommon 5 years after episcleral brachytherapy. Follow-up intervals can be adjusted to reflect time to recurrence. Most of the eyes with recurrent tumor can be salvaged by conservative methods. Copyright © 2017 Elsevier Inc. All rights reserved.

Background: Genetic factors are the main cause of early miscarriage. This study aimed to investigate aneuploidy in spontaneous abortion by fluorescence in situ hybridization (FISH) using probes for 13, 16, 18, 21, 22, X and Y chromosomes. Methods: A total of 840 chorionic samples from spontaneous abortion were collected and examined by FISH. We analyzed the incidence and type of abnormal cases and sex ratio in the samples. We also analyzed the relationship between the rate of aneuploidy and parental age, the rate of aneuploidy between recurrent abortion and sporadic abortion, the difference in incidence of aneuploidy between samples from previous artificial abortion and those from no previous induced abortion. Results: A total of 832 samples were finally analyzed. 368 (44.23%) were abnormal, in which 84.24% (310/368) were aneuploidies and 15.76% (58/368) were polyploidies. The first was trisomy16 (121/310), followed by trisomy 22, and X monosomy. There was no significant difference in the rate of aneuploidy in the advanced maternal age group (≥35 years old) and young maternal age group (<35 years old). However, the rate of trisomy 22 and the total rate of trisomies 21, 13, and 18 (the number of trisomy 21 plus trisomy 13 and trisomy 18 together) showed significantly different in two groups. We found no skewed sex ratio. There was no significant difference in the rate of aneuploidy between recurrent miscarriage and sporadic abortion or between the samples from previous artificial abortion and those from no previous artificial abortion. Conclusions: Aneuploidy is a principal factor of miscarriage and total parental age is a risk factor. There is no skewed sex ratio in spontaneous abortion. There is also no difference in the rate of aneuploidy between recurrent abortion and sporadic abortion or between previous artificial abortion and no previous induced abortion. PMID:26481744

The ideal surgical treatment of cholesteatoma has been subject to discussion for years because both traditional surgical techniques (canal wall down [CWD] and canal wall up [CWU] tympanoplasty) have their own advantages and disadvantages. A more recently propagated surgical approach, to combine the CWD or CWU tympanoplasty technique with obliteration of the mastoid and epitympanum, is showing promising results. To systematically review the literature on recurrent and residual cholesteatoma rates after single-stage CWU and CWD tympanoplasty with mastoid obliteration. A systematic search of literature was performed to identify relevant publications in multiple electronic databases. The initial search was conducted in December 2016 and was updated in July 2017. Each study was reviewed by 2 independent reviewers on predetermined eligibility criteria. The methodological quality was determined using the methodological index for nonrandomized studies (MINORS) scale, and the relevance to the current topic was determined using a 4-criterion checklist. The searches identified a total of 336 potentially relevant publications; 190 articles were excluded based on title and abstract. The full-text articles of the remaining 146 citations were assessed for eligibility, resulting in 22 articles. After assessing these remaining articles for methodological quality and relevance to the current topic, another 8 studies were excluded, and a total of 13 studies (1534 patients) were included. Of the 1534 patients who underwent CWD or CWU tympanoplasty with mastoid obliteration, the rate of recurrent disease was 4.6%, and the rate of residual disease was 5.4%. In CWU tympanoplasty with mastoid obliteration, these rates were 0.28% and 4.2%, respectively and in CWD tympanoplasty with mastoid obliteration, 5.9% and 5.8%, respectively. We show the recurrent and residual disease rates after either CWU or CWD tympanoplasty with mastoid obliteration to be qualitatively similar to, if not better than, previously reported rates of for nonobliterative techniques. In this study, the lowest recurrent and residual rates were reported when combining the CWU tympanoplasty with mastoid obliteration, on average 0.28 and 4.2%, respectively.

Giant cell tumors (GCTs) are benign, locally aggressive tumors. We examined the rate of local recurrence of spinal GCTs and sought to identify recurrence factors in patients who underwent surgery. Between 1995 and 2014, 94 mobile spine GCT patients were treated at our hospital, comprising 43 male and 51 female patients with an average age of 33.4 years. Piecemeal intralesional spondylectomy and total en bloc spondylectomy (TES) were performed. Radiotherapy was suggested for recurrent or residual GCT cases. Since denosumab was not available before 2014 in our country, only interferon and/or zoledronic acid was suggested. Of the 94 patients, four underwent conservative treatment and 90 underwent operations. Seventy-five patients (79.8%) were followed up for a minimum of 24 months or until death. The median follow-up duration was 75.3 months. The overall recurrence rate was 37.3%. Ten patients (13.3%) died before the last follow-up (median: 18.5 months). Two patients (2.6%) developed osteogenic sarcoma. The local recurrence rate was 80.0% (24/30) in patients who underwent intralesional curettage, 8.8% (3/34) in patients who underwent extracapsular piecemeal spondylectomy, and 0 (0/9) in patients who underwent TES. The risk factors for local recurrence were lesions located in the cervical spine (P = 0.049), intralesional curettage (P < 0.001), repeated surgeries (P = 0.014), and malignancy (P < 0.001). Malignant transformation was a significant risk factor for death (P < 0.001). Cervical spinal tumors, curettage, and nonintact tumors were risk factors for local recurrence. Intralesional curettage and malignancy were the most important significant factors for local recurrence and death, respectively.

The purpose of this study was to determine the outcomes and optimal practice patterns of definitive radiotherapy for primary vaginal cancer. Between 1993 and 2012, 49 patients were treated with definitive radiotherapy for primary vaginal cancer in three hospitals. Of these, 15 patients (31%) had clinically positive regional lymph node metastasis. A total of 34 patients (70%) received external beam radiotherapy with high-dose-rate brachytherapy (interstitial or intracavitary), and 8 (16%) (with small superficial Stage I tumors) were treated with local radiotherapy. The median follow-up was 33 months (range: 1-169 months). The 3-year overall survival (OS), disease-free survival (DFS), and loco-regional control (LRC) rates were 83%, 59% and 71%, respectively. In multivariate analysis, the histological type (P = 0.044) was significant risk factors for LRC. In Federation of Gynecology and Obstetrics (FIGO) Stage I cases, 3 of 8 patients (38%) who did not undergo prophylactic lymph node irradiation had lymph node recurrence, compared with 2 of 12 patients (17%) who underwent prophylactic pelvic irradiation. For Stage III-IV tumors, the local recurrence rate was 50% and the lymph node recurrence rate was 40%. Patients with FIGO Stage I/II or clinical Stage N1 had a higher recurrence rate with treatment using a single modality compared with the recurrence rate using combined modalities. In conclusion, our treatment outcomes for vaginal cancer were acceptable, but external beam radiotherapy with brachytherapy (interstitial or intracavitary) was needed regardless of FIGO stage. Improvement of treatment outcomes in cases of FIGO Stage III or IV remains a significant challenge. © The Author 2015.

The purpose of this study was to evaluate the outcomes of elderly patients 75 years of age or older with recurrent non-small cell lung cancer (NSCLC). A total of 1237 consecutive patients with NSCLC underwent pulmonary resection at our institution. Of these patients, 280 experienced postoperative recurrence. The rate of the post-recurrence survival and predictors were analyzed independently in a group of younger patients (<75 years) and a group of elderly patients (≥75 years). There were 215 younger patients (<75 years) and 65 elderly (≥75 years) patients at the time of diagnosis of recurrence. The median post-recurrence survival time and the five-year survival rate of all cases were 25 months and 20.8%, respectively. There were no significant survival differences between the younger and elderly groups (p = 0.20). A univariate analysis determined that gender, Eastern Cooperative Oncology Group performance status, smoking status, histological type and epithelial growth factor receptor (EGFR) mutation status were factors influencing the post-recurrence survival among the elderly patients. In addition, a multivariate analysis determined the EGFR mutation status to be an independent prognostic factor for the post-recurrence survival. Elderly patients 75 years of age or older in this study achieved satisfactory long-term outcomes.

The aim of the present study was to investigate the risk factors for postoperative recurrence of spinal tumors by logistic regression analysis and analysis of prognostic factors. In total, 77 male and 48 female patients with spinal tumor were selected in our hospital from January, 2010 to December, 2015 and divided into the benign (n=76) and malignant groups (n=49). All the patients underwent microsurgical resection of spinal tumors and were reviewed regularly 3 months after operation. The McCormick grading system was used to evaluate the postoperative spinal cord function. Data were subjected to statistical analysis. Of the 125 cases, 63 cases showed improvement after operation, 50 cases were stable, and deterioration was found in 12 cases. The improvement rate of patients with cervical spine tumor, which reached 56.3%, was the highest. Fifty-two cases of sensory disturbance, 34 cases of pain, 30 cases of inability to exercise, 26 cases of ataxia, and 12 cases of sphincter disorders were found after operation. Seventy-two cases (57.6%) underwent total resection, 18 cases (14.4%) received subtotal resection, 23 cases (18.4%) received partial resection, and 12 cases (9.6%) were only treated with biopsy/decompression. Postoperative recurrence was found in 57 cases (45.6%). The mean recurrence time of patients in the malignant group was 27.49±6.09 months, and the mean recurrence time of patients in the benign group was 40.62±4.34. The results were significantly different (P<0.001). Recurrence was found in 18 cases of the benign group and 39 cases of the malignant group, and results were significantly different (P<0.001). Tumor recurrence was shorter in patients with a higher McCormick grade (P<0.001). Recurrence was found in 13 patients with resection and all the patients with partial resection or biopsy/decompression. The results were significantly different (P<0.001). Logistic regression analysis of total resection-related factors showed that total resection should be the preferred treatment for patients with benign tumors, thoracic and lumbosacral tumors, and lower McCormick grade, as well as patients without syringomyelia and intramedullary tumors. Logistic regression analysis of recurrence-related factors revealed that the recurrence rate was relatively higher in patients with malignant, cervical, thoracic and lumbosacral, intramedullary tumors, and higher McCormick grade and patient received partial resection or biopsy. Tumor property, tumor location, McCormick grade, tumor resection, and intramedullary tumors are risk factors for the recurrence of spinal tumors. Clinical assessment of these risk factors may be helpful in selecting appropriate treatment strategies.

Background In Crohn's disease (CD), studies associating phenotype at diagnosis and subsequent disease activity are important for patient counselling and health care planning. Aims To calculate disease recurrence rates and to correlate these with phenotypic traits at diagnosis. Methods A prospectively assembled uniformly diagnosed European population based inception cohort of CD patients was classified according to the Vienna classification for disease phenotype at diagnosis. Surgical and non‐surgical recurrence rates throughout a 10 year follow up period were calculated. Multivariate analysis was performed to classify risk factors present at diagnosis for recurrent disease. Results A total of 358 were classified for phenotype at diagnosis, of whom 262 (73.2%) had a first recurrence and 113 patients (31.6%) a first surgical recurrence during the first 10 years after diagnosis. Patients with upper gastrointestinal disease at diagnosis had an excess risk of recurrence (hazard ratio 1.54 (95% confidence interval (CI) 1.13–2.10)) whereas age ⩾40 years at diagnosis was protective (hazard ratio 0.82 (95% CI 0.70–0.97)). Colonic disease was a protective characteristic for resective surgery (hazard ratio 0.38 (95% CI 0.21–0.69)). More frequent resective surgical recurrences were reported from Copenhagen (hazard ratio 3.23 (95% CI 1.32–7.89)). Conclusions A mild course of disease in terms of disease recurrence was observed in this European cohort. Phenotype at diagnosis had predictive value for disease recurrence with upper gastrointestinal disease being the most important positive predictor. A phenotypic North‐South gradient in CD may be present, illustrated by higher surgery risks in some of the Northern European centres. PMID:16361306

Patients with primary melanoma of the scalp have been reported to have worse disease-related outcomes compared with other anatomical regions. There are few studies in the literature specifically addressing recurrence patterns and treatment outcomes for primary scalp melanoma as a discrete anatomical sub-region. We sought to identify key features adversely influencing disease control and survival and to clarify the role of resection plane, margin, and method of reconstruction in the management of this disease process. A retrospective clinical study of medical records was performed evaluating all patients with primary melanoma of the scalp treated at two hospitals in southeast Queensland between 2004 and 2014. A total of 107 patients were eligible for analysis. There were 46 recurrences in 38 patients in the cohort accounting for a recurrence rate of 35.5%. The local recurrence rate was 15.9% with 12 in-transit metastases after diagnosis. Regional and distant recurrence rates were 12.1% and 15%, respectively. At a median follow up of 30.5 months, disease-free survival was 47% and overall survival was also 47%. On multi-variate analysis, the deeper resection plane (sub-galeal) had a lower disease-free survival rate compared with the supra-galeal resection plane (P = 0.032). Our results support the hypothesis that primary scalp melanoma represents a unique aggressive subcategory with high rates of in-transit disease and poor disease-related and survival outcomes. There is a need for robust prospective comparative studies to address the significance of resection plane in the management of patients with scalp melanoma. © 2016 Wiley Periodicals, Inc.

Disease course in inflammatory bowel disease (IBD) is variable and difficult to predict. To optimize prognosis, it is of interest to identify phenotypic characteristics at disease onset and other prognostic factors that predict disease course. The aim of this study was to evaluate such factors in a population-based IBD group. IBD patients diagnosed between 1 January 1991 and 1 January 2003 were included. A follow-up questionnaire was developed and medical records were reviewed. Patients were classified according to phenotype at diagnosis and risk factors were registered. Disease severity, cumulative medication use, and "surgical" and "nonsurgical" recurrence rates were calculated as outcome parameters. In total, 476 Crohn's disease (CD), 630 ulcerative colitis (UC), and 81 indeterminate colitis (IC) patients were diagnosed. In CD (mean follow-up 7.6 years), 50% had undergone resective surgery. In UC (mean follow-up 7 years), colectomy rate was 8.3%. First year cumulative recurrence rates per 100 patient-years for CD, UC, and IC were 53, 44, and 42%, respectively. In CD, small bowel localization and stricturing disease were negative prognostic factors for surgery, as was young age. Overall recurrence rate was increased by young age and current smoking. In UC, extensive colitis increased surgical risk. In UC, older age at diagnosis initially increased recurrence risk but was subsequently protective. This population-based IBD study showed high recurrence rates in the first year. In CD, small bowel localization, stricturing disease, and young age were predictive for disease recurrence. In UC, extensive colitis and older age at diagnosis were negative prognostic predictors.

As laparoscopy gained popularity, minimal invasive approach was also applied for hernia surgery. Unfortunately the initial efforts were disappointing due to high early recurrence rate. Experience led to refinement of technique, with acceptable recurrence rates. This combined with the advantages of minimal invasive surgery resulted in a gradual rise in worldwide acceptance of this technique. Our preferred approach for inguinal hernia repair is laparoscopic totally extraperitoneal (TEP); only in complicated hernias (sliding or incarcerated inguinal hernias) we use the transabdominal preperitoneal repair (TAPP) technique. Records of all patients who underwent TEP repair for inguinal hernia at our centre in last 15 years were retrospectively analysed. We have done 8659 hernias in 7023 patients by TEP approach. We have developed minor modifications for the TEP repair over the years. Out of total 8659 hernias 5262 was right sided and 3397 left sided. Of these, 5387 hernias were unilateral and the remainder were bilateral; 324 cases of recurrent hernias following open repair underwent TEP. Most of the patients were males with a mean age of 46 years. Indirect hernias were most common, followed by direct hernias. Right-sided hernias were more common than left-sided hernias. In 39 cases conversion to TAPP was needed. There were intra-operative problems in 250 patients (3.56%).Postoperative complications were seen in 192 patients (2.73%), majority of which were minor complications. There was no mortality. Recurrence rate was 0.39%. The TEP technique is comfortable and highly effective. Our port placement maintains triangular orientation that is considered vital to the ergonomics of laparoscopy. Nearly 98-99% of inguinal hernias can be treated by TEP approach with excellent results.

Background: The high demands to the glenohumeral joint and the violent shoulder blows experienced during martial arts (MA) could compromise return to sports and increase the recurrence rate after arthroscopic stabilization for anterior shoulder instability in these athletes. Purpose: To report the functional outcomes, return to sports, and recurrences in a series of MA athletes with anterior shoulder instability treated with arthroscopic stabilization with suture anchors. Study Design: Case series; Level of evidence, 4. Methods: A total of 20 consecutive MA athletes were treated for anterior shoulder instability at a single institution between January 2008 and December 2013. Range of motion (ROM), the Rowe score, a visual analog scale (VAS), and the Athletic Shoulder Outcome Scoring System (ASOSS) were used to assess functional outcomes. Return-to-sport and recurrence rates were also evaluated. Results: The mean age at the time of surgery was 25.4 years (range, 18-35 years), and the mean follow-up was 71 months (range, 36-96 months). No significant difference in preoperative and postoperative shoulder ROM was found. The Rowe, VAS, and ASOSS scores showed statistical improvement after surgery (P < .001). In all, 19 athletes (95%) returned to sports. However, only 60% achieved ≥90% recovery after surgery. The recurrence rate was 20%. Conclusion: In this retrospective study of a consecutive cohort of MA athletes, arthroscopic anterior shoulder stabilization significantly improved functional scores. However, only 60% of the athletes achieved the same level of competition, and there was a 20% recurrence rate. PMID:28932751

The objective of this study was to analyse the distribution and antimicrobial resistance of bacterial uropathogens isolated from outpatients at Henan Provincial People's Hospital. A total of 1419 samples from 823 newly diagnosed and 596 recurrent UTI outpatients culture positive. Escherichia coli was the most common uropathogen. Compared with the recurrent group, the newly diagnosed group had a higher isolation rate of E. coli and Enterobacter cloacae but a lower isolation rate of Klebsiella pneumoniae, Pseudomonas aeruginosa and Acinetobacter spp. Except for P. aeruginosa, the resistance of Gram-negative bacteria to most antibiotics was less than 30%. All Enterococcus and Staphylococcus spp. were sensitive to linezolid, vancomycin and teicoplanin. Both Gram-negative and -positive bacteria exhibited high susceptibility to fosfomycin. Uropathogens isolated from recurrent outpatients had higher resistance rates than did those isolated from newly diagnosed outpatients. Our study indicated that fosfomycin might be an excellent treatment option for outpatients with UTIs.

With the expansion of surgical criteria, the comparative efficacy between surgical resection (SR) and liver transplantation (LT) for hepatocellular carcinoma is inconclusive. This study aimed to develop a prognostic nomogram for predicting recurrence-free survival of hepatocellular carcinoma patients after resection and explored the possibility of using nomogram as treatment algorithm reference. From 2003 to 2012, 310 hepatocellular carcinoma patients within Hangzhou criteria undergoing resection or liver transplantation were included. Total tumor volume, albumin level, HBV DNA copies and portal hypertension were included for constructing the nomogram. The resection patients were stratified into low- and high-risk groups by the median nomogram score of 116. Independent risk factors were identified and a visually orientated nomogram was constructed using a Cox proportional hazards model to predict the recurrence risk for SR patients. The low-risk SR group had better outcomes compared with the high-risk SR group (3-year recurrence-free survival rate, 71.1% vs 35.9%; 3-year overall survival rate, 89.8% vs 78.9%, both P<0.001). The high-risk SR group was associated with a worse recurrence-free survival rate but similar overall survival rate compared with the transplantation group (3-year recurrence-free survival rate, 35.9% vs 74.1%, P<0.001; 3-year overall survival rate, 78.9% vs 79.6%, P>0.05). This nomogram offers individualized recurrence risk evaluation for hepatocellular carcinoma patients within Hangzhou criteria receiving resection. Transplantation should be considered the first-line treatment for high-risk patients. Copyright © 2017 The Editorial Board of Hepatobiliary & Pancreatic Diseases International.

This study was designed to investigate the associations between clinical, pathologic, and therapeutic parameters of facial basal cell carcinoma (BCC) and recurrence rates in patients treated at an advanced care center. A retrospective cohort study was performed. Patients who presented to an advanced care center within a 6-year period with facial BCC and who received surgical treatment were included for further review according to predefined inclusion criteria. The predictor variable was defined as "negative-margin (R0) resection after the first surgery". The primary outcome variable was defined as "BCC recurrence". Descriptive and inferential statistics were computed. The significance level was set at P ≤ 0.05. A total of 71 patients (29 female, 42 male; average age: 71.76 years) were found to meet all of the study inclusion criteria. All BCCs had been referred, and 50.7% had been submitted to previous surgery. The mean ± standard deviation tumor diameter was 2.3 ± 1.8 cm. Recurrence of BCC was observed in 11 patients (15.5%). Large tumor diameters, increased patient age, and failure to achieve R0 resection at the first surgical appointment significantly increased recurrence rates. Complete facial BCC excision at the first surgical appointment is pivotal in reducing the likelihood of recurrence. The influence of the anatomic location of facial BCC on recurrence rates may be limited. © 2016 The International Society of Dermatology.

To compare recurrence rates between prospectively collected and retrospectively collected data on primary anterior shoulder dislocations, as this could influence the timing of surgical decision making. A comprehensive literature search of Medline, Embase, CINAHL, and hand searches was performed. Recurrence rates of anterior shoulder dislocations were collected from relevant articles, along with follow-up length, age, and gender. An independent sample t test was conducted to evaluate our hypothesis. A multiple linear regression model was used to examine the variance in recurrence rates while controlling for covariates. A total of 1,379 articles were identified, of which 25 were relevant to our study-16 prospective and 9 retrospective. The average rate of recurrence of anterior shoulder dislocations in retrospective studies (mean [M] = 45.2, standard deviation [SD] = 31.67) was not significantly different from that in prospective studies (M = 56.7, SD = 22.55). The 95% confidence interval for the difference of the means ranged from -34.05 to 10.91. After controlling for covariates with the multiple linear regression, only 1.9% of the variance in recurrence rates was due to study type and was not significant (P = .42). The t test performed to evaluate our hypothesis was also not significant t(23) = -1.07, P = .298. When comparing prospective and retrospective studies, there was no significant difference in recurrence rates of primary anterior shoulder dislocations treated nonoperatively. The average redislocation rate was 56.7% in prospective studies and 45.2% in retrospective studies. Furthermore, the majority of this difference was accounted for by varying rates between age groups. Further research is needed to determine the risk of redislocation in specific age groups, to guide treatment decisions based on varying risk. Systematic review of Level II and III studies.

Introduction Total thyroidectomy has been used to treat patients with malignant thyroid disease. But for patients with benign thyroid disease, the safety and efficacy of total thyroidectomy is a matter of debate. Subtotal thyroidectomy that was previously the treatment of choice for benign thyroid disease has been associated with high recurrence rates. The risk of permanent complications is greatly increased in patients who undergo surgery for recurrence of benign thyroid disease. Total thyroidectomy is an operation that can be safely performed, with low incidence of permanent complications, which allows one to broaden its indications in various benign thyroid diseases, thus avoiding future recurrences and reoperations. Aim To assess the benefits of total thyroidectomy for benign thyroid diseases. Materials and Methods This randomized prospective study was conducted between Feb 2013 and Nov 2014 in the Department of General Surgery at Bangalore Medical College and Research Institute. It included 116 patients undergoing total thyroidectomy procedure for benign thyroid disease. All cases were followed-up for a period of 6 months for incidence of RLN palsy, hypoparathyroidism, disease recurrence and number of incidental malignancies detected on postoperative histological analyses of the thyroid specimens. Results Most of the patients were in the third decade of their lives. The female to male ratio was 6.7:1. Total thyroidectomy was done for 116 benign thyroid diseases with multinodular goiter as the most common diagnosis. The incidence of postoperative hypocalcaemia was 16.37% (however, only 1 patient developed permanent hypocalcaemia) and that of wound infection was 2.58% and seroma formation was 2.58%. None of the patients included in this study had haematoma formation or RLN paralysis. An incidental malignancy was identified in 11.20% patients. Conclusion Total thyroidectomy shows benefits in eradicating multinodular goiter, alleviating Grave’s opthalmopathy, treating Hashimoto’s thyroiditis and preventing recurrence. It decreases the likelihood of future operations for recurrent disease or completion thyroidectomy for incidental thyroid cancer thus decreasing the associated risks of increased morbidity associated with second operation. Therefore, for benign thyroid diseases requiring surgical management total thyroidectomy can be considered the treatment of choice. PMID:27504342

AIM: To investigate the correlation among the presence and degree of gastric metaplasia of duodenal regenerating mucosa, the deformity of bulb and the recurrence of duodenal ulcer. METHODS: A total of 99 patients with duodenal ulcer were treated with H2-antagonist with or without antimicrobial therapy. All patients received follow-up endoscopic examinations 6 wk after treatment. When the ulcer(s) were noted to be healed, two biopsies were taken from the ulcer scar for histological study of gastric metaplasia, and 4 biopsies were taken from antrum for Helicobacter pylori (H pylori) study. Out of these cases, 44 received further follow-up endoscopic examinations after 3, 6 and 12 mo respectively for studying the recurrence rate of duodenal ulcers. The correlation among ulcer recurrence, degree of gastric metaplasia of regenerating mucosa, bulbar deformity, and colonization of H pylori in the stomach was then studied. RESULTS: The results showed that there was a strong correlation between the deformity of duodenal bulb and the degree of gastric metaplasia of regenerating duodenal mucosa. The recurrence rate of duodenal ulcer had a significant difference between patients with and without H pylori colonization in the stomach (P<0.001). The greater the degree of gastric metaplasia of duodenal regenerating mucosa, the higher the recurrence rate of duodenal ulcer (P = 0.021). The more deformed the duodenal bulb, the higher the incidence of recurrence of duodenal ulcer (P = 0.03). CONCLUSION: There is a correlation among deformity of duodenal bulb, gastric metaplasia of duodenal regenerating mucosa and recurrence of duodenal ulcer. A more severely deformed duodenal bulb is closely related to a greater extent of gastric metaplasia. Both factors contribute to the recurrence of duodenal ulcer. PMID:15793868

To date, there are no prospective randomized studies that compare the outcome of endoscopic repair of primary versus recurrent inguinal hernias. It is therefore now attempted to answer that key question on the basis of registry data. In total, 20,624 patients were enrolled between September 1, 2009, and April 31, 2013. Of these patients, 18,142 (88.0%) had a primary and 2482 (12.0%) had a recurrent endoscopic repair. Only patients with male unilateral inguinal hernia and with a 1-year follow-up were included. The dependent variables were intra- and postoperative complications, reoperations, recurrence, and chronic pain rates. The results of unadjusted analyses were verified via multivariable analyses. Unadjusted analysis did not reveal any significant differences in the intraoperative complications (1.28 vs 1.33%; p = 0.849); however, there were significant differences in the postoperative complications (3.20 vs 4.03%; p = 0.036), the reoperation rate due to complications (0.84 vs 1.33%; p = 0.023), pain at rest (4.08 vs 6.16%; p < 0.001), pain on exertion (8.03 vs 11.44%; p < 0.001), chronic pain requiring treatment (2.31 vs 3.83%; p < 0.001), and the recurrence rates (0.94 vs 1.45%; p = 0.0023). Multivariable analysis confirmed the significant impact of endoscopic repair of recurrent hernia on the outcome. Comparison of perioperative and 1-year outcome for endoscopic repair of primary versus recurrent male unilateral inguinal hernia showed significant differences to the disadvantage of the recurrent operation. Therefore, endoscopic repair of recurrent inguinal hernias calls for particular competence on the part of the hernia surgeon.

Surgery for recurrent/residual pituitary adenomas is increasingly being performed through endoscopic surgery. Whether this new technology has altered the indications and outcomes of surgery is unknown. We conducted a systematic review and meta-analysis of published studies to compare the indications and outcomes between microscopic and endoscopic approaches. A PubMed search was conducted (1985-2015) to identify surgical series of endoscopic endonasal and microscopic transsphenoidal resection of residual or recurrent pituitary adenomas. Data were extracted regarding tumor characteristics, surgical treatment, extent of resection, endocrine remission, visual outcome, and complications. Twenty-one studies met inclusion criteria. A total of 292 patients were in the endoscopic group, and 648 patients were in the microscopic group. Endoscopic cases were more likely nonfunctional (P < 0.001) macroadenomas (P < 0.001) with higher rates of cavernous sinus invasion (P = 0.012). The pooled rate of gross total tumor resection was 53.5% for the endoscopic group and 46.6% for the microscopic group. Endocrine remission was achieved in 53.0% and 46.7% of patients, and visual improvement occurred in 73.2% and 49.6% for the endoscopic and microscopic groups. Cerebrospinal fluid leak and pituitary insufficiency were higher in the endoscopic group. This meta-analysis indicates that the use of the endoscope to reoperate on residual or recurrent adenomas has only led to modest increases in resection rates. However, larger more complex cases are being tackled, so direct comparisons are misleading. The most dramatic change has been in visual improvement along with modest increases in risk. Reoperation for recurrent or residual adenomas is a safe and effective treatment option. Copyright © 2017 Elsevier Inc. All rights reserved.

Gastrointestinal foreign bodies are commonly encountered; however, little knowledge exists as to the causes of foreign body ingestions and why they occur repeatedly in some patients. To identify and define patients at high risk for recurrent foreign body ingestion. A retrospective chart review of foreign body ingestion was conducted at a tertiary care medical centre over an 11-year period. Variables analyzed included age, sex, incarceration status, Diagnostic and Statistical Manual of Mental Disorders-IV diagnosis, success of endoscopy, type of sedation used, method of extraction, complications, presence of gastrointestinal pathology, and incidence of recurrent food impaction or foreign body. A total of 159 patients with a foreign body ingestion were identified. One hundred fourteen (77%) experienced a single episode of ingestion and 45 (23%) experienced multiple ingestions. Of the patients with multiple ingestions, 27 (60%) had recurrent food impactions while 18 (40%) ingested foreign objects. In the recurrent ingestor group, a psychiatric disorder had been diagnosed in 16 patients (35.6%) and there were 13 incarcerated individuals (28.9%). The average number of recurrences was 2.6 per patient (117 total recurrences). Individuals with a psychiatric disorder experienced 3.9 recurrences per patient, while prisoners averaged 4.1 recurrences per patient. The combination of a psychiatric disorder and being incarcerated was associated with the highest recurrence rate (4.33 per patient). Multivariable logistic regression revealed that male sex (OR 2.9; P=0.022), being incarcerated (OR 3.0; P=0.024) and the presence of a psychiatric disorder (OR 2.5; P=0.03) were risk factors for recurrent ingestion. Risk factors for recurrent ingestion of foreign bodies were male sex, being incarcerated and the presence of a psychiatric disorder.

Midline dorsal plication is an efficient and safe surgical technique to correct chordee. We investigated the efficacy of midline dorsal plication for recurrent chordee in complicated hypospadias reoperations. We retrospectively evaluated the charts of 25 boys who underwent reoperation between 1999 and 2004 due to complications of primary hypospadias repair other than meatal stenosis. A total of 15 cases were initially managed elsewhere for primary repair or complications. The etiology of recurrent chordee was defined at surgical correction. When recurrent chordee was noted a midline dorsal plication was performed. Of 25 patients 10 had previously undergone chordee repair. Nine of these patients were observed to have recurrent chordee and 1 had de novo chordee. A total of 10 patients had recurrent or delayed onset chordee. Mean patient age at primary repair was 6.28 years (range 1 to 33). Mean age at last operation for chordee was 15.9 years (range 4 to 66). Mean interval to recurrent chordee was 6 years (range 1 to 16), excluding a 66-year-old blind patient who did not know when recurrent chordee developed. Five patients had chordee recur before puberty at a mean interval of 2.6 years. Mean reoperation rate was 2.4 for recurrent chordee cases and 2.6 for chordee-free cases. Mean followup after midline dorsal plication for recurrent chordee repair was 22 months (range 8 to 56), while mean followup in pubertal and postpubertal cases was 20 months. No recurrence of chordee or surgery related morbidity was observed after recurrent chordee repair by midline dorsal plication. Chordee may recur during puberty following successful chordee repair. The midline dorsal plication technique is simple, efficient and safe even in patients who have undergone multiple surgeries for hypospadias and chordee repair.

Liver fibrosis is associated with the prognosis of patients with hepatocellular carcinoma (HCC) after treatment. The laboratory marker for liver fibrosis, the FIB-4 index, is reportedly correlated with the degree of liver fibrosis. We evaluated the predictive value of FIB-4 index on the recurrence and survival of HCC patients who underwent curative hepatectomy. A total of 431 consecutive patients who underwent hepatectomy for primary, nonrecurrent HCC were analyzed. The FIB-4 index was calculated from the patient's age, serum alanine aminotransferase and aspartate aminotransferase levels, and platelet count at the time of HCC diagnosis. Postoperative recurrence and survival rates were compared according to tumor characteristics, tumor markers, Child-Pugh class, and the FIB-4 index. The pretreatment FIB-4 index was associated with recurrence and survival rates, independent of HCC progression or tumor marker levels in a multivariate analysis. Recurrence rates after hepatectomy were higher in patients with a FIB-4 index >3.25 versus ≤3.25 (5-year recurrence rates 69.6% vs 54.8%; P = .0049). Survival was also worse in patients with a FIB-4 index >3.25 than those with a FIB-4 index ≤3.25 (5-year survival rates 67.1% vs 72.2%; P = .0030). The FIB-4 index is a predictive marker for long-term outcomes in patients with HCC treated with curative hepatic resection. Copyright © 2015 Elsevier Inc. All rights reserved.

The aim of this study was to emphasize the importance of adequate primary surgery in cases of medullary carcinoma of the thyroid. We retrospectively reviewed 44 cases of medullary carcinoma of the thyroid treated in Government General Hospital, Chennai between 1987 and 2002. Patients who underwent total thyroidectomy with only central compartment dissection were compared with those who had undergone total thyroidectomy with meticulous triple compartment (bilateral lateral and central groups) nodal dissection. The group of total thyroidectomy with only central compartment dissection had a high rate of lymph nodal recurrence and persistent hypercalcitoninemia compared with the group with total thyroidectomy with meticulous triple compartment nodal dissection. (chi square, 4.503; P > 0.05). Primary surgery with total thyroidectomy with meticulous triple compartment dissection is superior to total thyroidectomy with central compartment dissection alone in terms of preventing nodal and local recurrences and achieving normal (basal and stimulated) serum calcitonin levels postoperatively.

Birt-Hogg-Dubé syndrome (BHDS) is a recently recognized inherited multiple cystic lung disease causing recurrent pneumothoraces. Similarly to the lesions in patients with lymphangioleiomyomatosis (LAM), the pulmonary cysts are innumerable and widely dispersed and cannot all be removed. We recently described a total pleural covering (TPC) that covers the entire visceral pleura with oxidized regenerated cellulose (ORC) mesh. TPC successfully prevented the recurrence of pneumothorax in LAM patients. The purpose of this study was to evaluate the effect of an ORC pleural covering on pneumothorax recurrence in BHDS patients. This retrospective study enrolled a total of 81 pneumothorax patients with the diagnosis of BHDS who underwent 90 covering surgeries from January 2010 to August 2017 at Tamagawa Hospital. During the first half of the study period, a lower pleural covering (LPC) which covered the affected area with ORC mesh was mainly used to treat 38 pneumothoraces. During the second half of the study period, TPC was primarily performed for 52 pneumothoraces. All the thoracoscopic surgeries were successfully performed without serious complications (≥ Clavien-Dindo grade III). The median follow-up periods after LPC/TPC were 66/34 months, respectively. Pneumothorax recurrence rates after LPC at 2.5/5/7.5 years postoperatively were 5.4/12/42%, respectively; none of the patients who had underwent TPC developed postoperative pneumothorax recurrence (P = 0.032). TPC might be an effective option for surgical treatment of intractable pneumothorax in patients with BHDS.

In the present study, we aimed to test the value of CAAP-AF score for prediction of atrial fibrillation (AF) recurrence at follow-up in a group of our patients treated by balloon cryoablation. A total of 283 symptomatic drug-refractory AF patients [261 (92%) with paroxysmal AF] who underwent pulmonary vein isolation (PVI) with second-generation cryoballoon between April 2012 and October 2016 were included. The CAAP-AF score was calculated for every patient. A total of 283 patients [68 female (20%), mean age 59.8 ± 11.4 years] were included in the present analysis. Eighty-nine patients (31%) had hypertension and 13 (4%) had coronary artery disease. The mean left atrial diameter and left ventricular ejection fraction were 40.6 ± 7.0 mm and 60.0 ± 9.1%, respectively. The mean CHA 2 DS 2 -VASc score was 1.2 ± 1.1, and mean number of prior failed antiarrhythmic drugs was 1.4 ± 0.8. At 18 ± 6 months follow-up, 25 patients (8.87%) developed AF recurrence. The recurrence rate was as follows: 3.17% (score 0-3), 8.47% (score 4), 16.28% (score 5), 6.67% (score 6), 23.08% (score 7), and 36.36% (score ≥8). The recurrence rate was 4.86% at a score <5 and 16.49% at a value ≥5; a score cutoff ≥5 predicted AF recurrence with a sensitivity 64% and specificity 68%. The present analysis suggests the usefulness of CAAP-AF scoring system, with its simple and easily obtained six clinical variables, to predict AF recurrence after PVI by means of second-generation cryoballoon. A score value ≥5 predicted AF recurrence with a sensitivity 64% and specificity 68%.

[Long-term follow-up results after open small umbilical hernia repairs].

Adult umbilical hernia is a common surgical condition in the fifth and sixth decade of life. Despite the high frequency of umbilical hernia repairs, disappointingly high recurrence rates after simple suture repairs are reported, amounting to 54%. In addition, it is reported that with the rising frequency of recurrences, the size of the hernial sac and gate gradually increases. Therefore we decided to find out the incidence of recurrences after operative repair of an umbilical hernia at our department. Patient data for this retrospective study focusing on the period between 2006 and 2010 were obtained from the electronic hospital database. Patients with umbilical hernia and the abdominal wall defect up to 3 cm who underwent primary elective procedure were included in the study. Patients with incisional hernias were excluded. All patients were contacted at least 3 years after operation to confirm the accuracy of data. A total of 127 patients were included in this study. In the abovementioned period, no mesh was used during primary surgery in any of the patients. Recurrence occurred in a total of 13.4% of patients. Approximately 40% of patients with the first recurrence were re-operated at our department, 30% of patients were re-operated in other hospitals and the rest have not sought medical attention in respect of the recurrence. Patients with recurrence did not differ from the others as regards age, body mass index or surgical site infection development. Due to the high recurrence rates after operative sutures of the umbilical hernias there is a need to thoroughly consider the potential risk factors such as the body mass index and the abdominal wall defect size. Therefore, it is recommended to use the mesh more widely during primary surgery, especially in obese patients with BMI over 30 and the wall defect size exceeding 3 cm. The question remains whether to use the mesh in all overweight patients and with wall defect smaller than 3 cm.

Progesterone is essential for the maintenance of pregnancy. However, whether progesterone supplementation in the first trimester of pregnancy would increase the rate of live births among women with a history of unexplained recurrent miscarriages is uncertain. We conducted a multicenter, double-blind, placebo-controlled, randomized trial to investigate whether treatment with progesterone would increase the rates of live births and newborn survival among women with unexplained recurrent miscarriage. We randomly assigned women with recurrent miscarriages to receive twice-daily vaginal suppositories containing either 400 mg of micronized progesterone or matched placebo from a time soon after a positive urinary pregnancy test (and no later than 6 weeks of gestation) through 12 weeks of gestation. The primary outcome was live birth after 24 weeks of gestation. A total of 1568 women were assessed for eligibility, and 836 of these women who conceived naturally within 1 year and remained willing to participate in the trial were randomly assigned to receive either progesterone (404 women) or placebo (432 women). The follow-up rate for the primary outcome was 98.8% (826 of 836 women). In an intention-to-treat analysis, the rate of live births was 65.8% (262 of 398 women) in the progesterone group and 63.3% (271 of 428 women) in the placebo group (relative rate, 1.04; 95% confidence interval [CI], 0.94 to 1.15; rate difference, 2.5 percentage points; 95% CI, -4.0 to 9.0). There were no significant between-group differences in the rate of adverse events. Progesterone therapy in the first trimester of pregnancy did not result in a significantly higher rate of live births among women with a history of unexplained recurrent miscarriages.

The optimal therapeutic approach for adult craniopharyngioma remains controversial. Some advocate for gross total resection (GTR), while others advocate for subtotal resection followed by adjuvant radiotherapy (STR + XRT). To conduct a systematic review and meta-analysis assessing the rate of recurrence in the follow-up of 3 yr in adult craniopharyngioma stratified by extent of resection and presence of adjuvant radiotherapy. MEDLINE (1946-July 1, 2016) and EMBASE (1980-June 30, 2016) were systematically reviewed. From1975 to 2013, 33 patients were treated with initial surgical resection for adult onset craniopharyngioma at our center and were reviewed for inclusion in this study. Data from 22 patients were available for inclusion as a case series in the systematic review. Eligible studies (n = 21) were identified from the literature in addition to a case series of our institutional experience. Three groups were available for analysis: GTR, STR + XRT, and STR. The rates of recurrence were 17%, 27%, and 45%, respectively. The risk of developing recurrence was significant for GTR vs STR (odds ratio [OR]: 0.24, 95% confidence interval [CI]: 0.15-0.38) and STR + XRT vs STR (OR: 0.20, 95% CI: 0.10-0.41). Risk of recurrence after GTR vs STR + XRT did not reach significance (OR: 0.63, 95% CI: 0.33-1.24, P = .18). This is the first and largest systematic review focusing on the rate of recurrence in adult craniopharyngioma. Although the rates of recurrence are favoring GTR, difference in risk of recurrence did not reach significance. This study provides guidance to clinicians and directions for future research with the need to stratify outcomes per treatment modalities. Copyright © 2017 by the Congress of Neurological Surgeons

To compare the outcomes of patients having thyroid cancer among Filipinos vs non-Filipinos. Retrospective medical record review. High-volume tertiary referral center in Toronto, Ontario, Canada. A total of 499 patients with thyroid cancer (36 Filipino and 463 non-Filipino) treated at Mount Sinai Hospital from January 1, 1984, to August 31, 2003, with a minimum 5-year follow-up period and a minimum 1.0-cm tumor size. Patients were identified from a thyroid cancer database. Data on patient, tumor, and treatment factors were collected along with outcomes. The presence of thyroid cancer recurrence, the rate of death from disease, and the time to recurrence. The 2 groups were similar for sex, age, history of head and neck radiation exposure, family history of thyroid cancer, follow-up time, tumor size, tumor pathologic findings, presence of tumor multifocality, stage of primary disease, type of thyroid surgery, use of postoperative radioactive iodine therapy, and use of external beam radiation therapy. Filipino patients experienced a thyroid cancer recurrence rate of 25% compared with 9.5% for non-Filipino patients (odds ratio, 3.20; 95% confidence interval, 1.23-7.49; P = .004). On multivariate analysis, the increased risk of thyroid cancer recurrence persisted for Filipino patients (odds ratio, 6.99; 95% confidence interval, 2.31-21.07; P < .001). No significant differences were noted between Filipino patients and non-Filipino patients regarding the rate of death from disease (5.6% vs 1.9%) and the time to recurrence (52.6 vs 53.1 months). Filipino patients have a significantly higher risk of thyroid cancer recurrence compared with non-Filipino patients. However, no significant difference was noted in the time to recurrence or the rate of death from disease. These findings justify a more aggressive initial management and follow-up regimen for Filipino patients with thyroid cancer.

Clinical and pathological characteristics of primary intraspinal hemangiopericytoma and choice of treatment.

Primary intraspinal hemangiopericytoma is a rare malignant mesenchymal tumor with high rates of recurrence and metastasis. Surgery is the main therapeutic procedure for this lesion. This clinical research was undertaken to analyze the pathological characteristics, clinical course, and the choice of treatment for this lesion. Twenty-three patients with primary intraspinal hemangiopericytomas were treated from 1987 to 2004. The clinical and imaging features, pathological findings, therapeutic procedures, and prognosis were analyzed retrospectively. Primary intraspinal hemangiopericytoma is more likely to attack middle-aged persons. The tumor mainly manifests as muscle weakness and sensor abnormalities. Microscopic examination showed slit-like vascular spaces and oral- or spindle-shaped cells with slightly acidic cytoplasm and oral nuclei. Tumors were subtotally resected in 11 patients, subtotally resected with postoperative radiotherapy in 4, totally resected in 5, and totally resected with postoperative radiotherapy in 3. Two patients were given spinal stabilization after total resection. Recurrence and metastatic rates were 50% and 0 in intradural patients. They were 73% and 27% in extradural patients, respectively. The tumor should be resected en bloc with the neighboring dural mater to reduce recurrence and metastasis. Patients with subtotal resection need adjuvant radiotherapy. Patients with evident spinal involvement may benefit from spinal stabilization. The prognosis of the lesion arising from the dural mater is better.

Purpose Venous thromboembolism (VTE) is common in patients with cancer. Long-term daily subcutaneous low molecular weight heparin has been standard treatment for such patients. The purpose of this study was to assess if an oral factor Xa inhibitor, rivaroxaban, would offer an alternative treatment for VTE in patients with cancer. Patient and Methods In this multicenter, randomized, open-label, pilot trial in the United Kingdom, patients with active cancer who had symptomatic pulmonary embolism (PE), incidental PE, or symptomatic lower-extremity proximal deep vein thrombosis (DVT) were recruited. Allocation was to dalteparin (200 IU/kg daily during month 1, then 150 IU/kg daily for months 2-6) or rivaroxaban (15 mg twice daily for 3 weeks, then 20 mg once daily for a total of 6 months). The primary outcome was VTE recurrence over 6 months. Safety was assessed by major bleeding and clinically relevant nonmajor bleeding (CRNMB). A sample size of 400 patients would provide estimates of VTE recurrence to within ± 4.5%, assuming a VTE recurrence rate at 6 months of 10%. Results A total of 203 patients were randomly assigned to each group, 58% of whom had metastases. Twenty-six patients experienced recurrent VTE (dalteparin, n = 18; rivaroxaban, n = 8). The 6-month cumulative VTE recurrence rate was 11% (95% CI, 7% to 16%) with dalteparin and 4% (95% CI, 2% to 9%) with rivaroxaban (hazard ratio [HR], 0.43; 95% CI, 0.19 to 0.99). The 6-month cumulative rate of major bleeding was 4% (95% CI, 2% to 8%) for dalteparin and 6% (95% CI, 3% to 11%) for rivaroxaban (HR, 1.83; 95% CI, 0.68 to 4.96). Corresponding rates of CRNMB were 4% (95% CI, 2% to 9%) and 13% (95% CI, 9% to 19%), respectively (HR, 3.76; 95% CI, 1.63 to 8.69). Conclusion Rivaroxaban was associated with relatively low VTE recurrence but higher CRNMB compared with dalteparin.

Recurrence after primary conventional inguinal herniorrhaphy occurs in approximately 10% of patients depending on the type of repair and expertise of the surgeon. The repair of the resulting recurrent hernia is a daunting task because of already weakened tissues and obscured and distorted anatomy. The failure rate of these repairs using an open anterior approach may reach as high as 36%. Because of such a high failure rate, a number of investigators have focused on repairing these difficult recurrent hernias laparoscopically using a tension-free approach. Some of the earlier reports suggested a low recurrence rate of 0.5% to 5% when a laparoscopic approach was used to repair these hernias. The purpose of this study was to evaluate the efficacy of laparoscopic treatment for recurrent hernias in our institutions. Between February 1991 and February 1995, 96 recurrent hernias were repaired in 85 patients (78 men and 7 women). There were 48 right, 26 left, and 11 bilateral hernias. The mean age of the patients was 59 years (range, 18-86 years); the mean height was 69 in. (range, 54-77 in.); and the mean weight was 176 pounds (range, 109-280 pounds). A total of 68 herniorrhaphies were performed using the transabdominal preperitoneal (TAPP) method: 19 using intraperitoneal on-lay mesh (IPOM) repair and 8 using the total extraperitoneal (TEP) method. The method of repair in one patient was not recorded. The mean operating time was 76 min (range, 47-172 min). Thirteen patients underwent additional procedures. Long-term follow-up was performed by questionnaire, examination, or both in 76 patients (85 hernias). Median follow-up time was 27 months (range, 2-56 months). There were four recurrences (2 in IPOM and 2 in TAPP). Three of these were repaired laparoscopically and one conventionally. There were 20 minor and 14 major complications and no mortality. One conversion occurred in the TAPP group. Mean postoperative stay was 1.4 days (range, 0-4 days). It was felt by 92% of the patients that their symptoms were completely relieved, whereas 4% of the patients continued to exhibit symptoms for which their hernia was repaired, and 3.6% failed to answer. As reported, 86% of the patients preferred their laparoscopic repair; 1% preferred the conventional repair; and 13% failed to reply. Afterward, 77% of the patients returned to normal activity, and 35% returned to vigorous activity within 4 weeks of surgery. Satisfaction with laparoscopic repair was expressed by 92% of the patients, whereas 8% either were dissatisfied or did not answer. In the end, 95% of the patients stated that they would recommend laparoscopic hernia surgery to their family and friends. These preliminary data show that laparoscopic repair of recurrent inguinal hernia is a safe alternative procedure with acceptable rates of recurrence and complications.

To report on local tumour control and eye preservation after gamma knife radiosurgery (GK-RS) to treat choroidal melanomas. A total of 189 patients with choroidal melanoma were treated with GK-RS, with treatment doses between 25 and 80 Grays. The main outcome measures of our retrospective analysis were local tumour control, time to recurrence, eye retention rate and the reason for and time to secondary enucleation. Patient-associated, tumour-associated and treatment-associated parameters were evaluated as potential risk factors. Local tumour control was achieved in 94.4% of patients. The estimated tumour control rates were 97.6% at 1 year, 94.2% at 5 years and 92.4% at 10 years after treatment. Recurrence was observed between 3.1 months and 60.7 months post-treatment (median: 13.5 months). Advanced tumour stage (Tumour, Node, Metastasis (TNM) 3-4) was the most important risk factor for recurrence (Fine-Gray model; subhazard ratio, SHR: 3.3; p=0.079). The treatment dose was not related to tumour recurrence. The eye preservation rate was 81.6% at 5 years after treatment, remaining stable thereafter. Twenty-five eyes (14.1%) had to be enucleated at between 17 days and 68.0 months (median: 13.9 months) after GK-RS, and advanced tumour stage (Cox model; p=0.005), treatment dose (p=0.048), pretreatment visual acuity (p=0.016), and retinal detachment (p=0.027) were risk factors for requiring enucleation. GK-RS achieved a high tumour control rate, comparable to linear accelerator-based radiotherapy. Advanced TNM stage was a predictive risk factor for tumour recurrence and for secondary enucleation after GK-RS. Lower treatment doses were unrelated to tumour recurrence, although they were associated with an improved eye retention rate.

Positive diffusion weighted imaging (DWI) on MRI is associated with increased recurrent stroke risk in TIA patients. Acute MRI aids in TIA risk stratification and diagnosis. To evaluate the feasibility and safety of TIA triage directly from the emergency department (ED) with acute MRI and neurological consultation. Consecutive ED TIA patients assessed by a neurologist underwent acute MRI/MRA of head/neck per protocol and were hospitalized if positive DWI, symptomatic vessel stenosis, or per clinical judgment. Stroke neurologist adjudicated the final TIA diagnosis as definite, possible, or not a cerebrovascular event. Stroke recurrence rates were calculated at 7, 90, 365 days and compared with predicted stroke rates derived from historical DWI and ABCD(2) score data. One hundred twenty-nine enrolled patients had a mean age of 69 years (± 17) and median ABCD(2) score of 3 (interquartile range [IQR] 3-4). During triage, 112 (87%) patients underwent acute MRI after a median of 16 h (IQR 10-23) from symptom onset. No patients experienced a recurrent event before imaging. Twenty-four (21%) had positive DWI and 8 (7%) had symptomatic vessel stenosis. Of the total cohort, 83 (64%) were discharged and 46 (36%) were hospitalized. By one-year follow-up, one patient in each group had experienced a stroke. Of 92 patients with MRI and index cerebrovascular event, recurrent stroke rates were 1.1% at 7 and 90 days. These were similar to predicted recurrence rates. TIA triage in the ED using a protocol with neurological consultation and acute MRI is feasible and safe. The majority of patients were discharged without hospitalization and rates of recurrent stroke were not higher than predicted. © 2014 World Stroke Organization.

Prophylactic colon surgery has increased life expectancy of familial adenomatous polyposis patients. Extracolonic manifestations are life limiting, above all duodenal adenomas. Severe duodenal adenomatosis or cancer may necessitate pancreas-preserving total duodenectomy or partial pancreatico-duodenectomy, mostly after previous proctocolectomy and often after limited local resections of duodenal adenomas. Scarce information on long-term postoperative outcome and quality of life after surgery for duodenal adenomatosis is available. Aim of the present study was to analyze perioperative and long-term outcome after PD and PPTD for FAP-associated duodenal adenomatosis, including QoL and recurrence of adenomas in the neoduodenum after PPTD. Thirty-eight patients, 27 after pancreas-preserving duodenectomy and 11 after partial pancreaticoduodenectomy, were included. Pancreas-preserving total duodenectomy was associated with shorter operation time and less blood loss than partial pancreatico-duodenectomy. Clinically relevant pancreatic fistula occurred in 31.5%. In-hospital mortality was 5.3%. Long-term follow-up revealed recurrent pancreatitis after pancreas-preserving total duodenectomy in 22% of patients, two (7.4%) required re-operation. Recurrent adenomatosis was detected in 26% of patients. Quality of life was comparable to the German normal population after both surgical procedures. Patients with postoperative complications showed worse results than those without complications. Disease-specific 10-year survival rate with respect to duodenal adenomatosis was 100%. Surgery for FAP-associated duodenal adenomatosis and cancer can be carried out with reasonable morbidity rates despite previous proctocolectomy. Long-term outcome, quality of life, and survival rates are favorable.

AIM: To assess effectiveness, complications, recurrence rate, and recent improvements of the anterior rectopexy procedure for treatment of total rectal prolapse. METHODS: MEDLINE, PubMed, EMBASE, and other relevant database were searched to identify studies. Randomized controlled trials, non-randomized studies and original articles in English language, with more than 10 patients who underwent laparoscopic ventral rectopexy for full-thickness rectal prolapse, with a follow-up over 3 mo were considered for the review. RESULTS: Twelve non-randomized case series studies with 574 patients were included in the review. No surgical mortality was described. Conversion was needed in 17 cases (2.9%), most often due to difficult adhesiolysis. Twenty eight patients (4.8%) presented with major complications. Seven (1.2%) mesh-related complications were reported. Most frequent complications were urinary tract infection and urinary retention. Mean recurrence rate was 4.7% with a median follow-up of 23 mo. Improvement of constipation ranged from 3%-72% of the patients and worsening or new onset occurred in 0%-20%. Incontinence improved in 31%-84% patients who presented fecal incontinence at various stages. Evaluation of functional score was disparate between studies. CONCLUSION: Based on the low long-term recurrence rate and favorable outcome data in terms of low de novo constipation rate, improvement of anal incontinence, and low complications rate, laparoscopic anterior rectopexy seems to emerge as an efficient procedure for the treatment of patients with total rectal prolapse.

The primary aims were to determine the rates of and prognostic factors for overall survival, disease-specific survival and disease-free survival following salvage total laryngectomy. Retrospective longitudinal study. Tertiary medical centres. A total of 142 patients in eastern Denmark undergoing salvage total laryngectomy for squamous cell carcinoma of the larynx or hypopharynx. 5-year overall survival, 5-year disease-specific survival, 5-year disease-free survival and prognostic factors for these outcomes. 5-year overall survival, disease-specific survival and disease-free survival were 37.7%, 54.9% and 55.3%, respectively. N classification at primary diagnosis, lymph node excision and postoperative complications within 1 year after salvage total laryngectomy were prognostic factors for shorter overall survival, disease-specific survival and disease-free survival. Residual tumour/recurrence was negatively associated with overall survival, close or involved resection margins with disease-specific survival, and second primary cancer was associated with longer disease-specific survival and disease-free survival. Nine per cent of all patients had residual tumour and 33.8% developed a recurrence. Our overall survival, disease-specific survival and disease-free survival findings are in accordance with previous studies. With the purpose of identifying recurrent tumour, we suggest extra attention being given to patients with higher N classification and need for lymph node excision during salvage total laryngectomy along with use of frozen sections. The high number of patients with recurrence within 1 year after salvage total laryngectomy occurred although thorough and regular follow-up visits were performed. © 2016 John Wiley & Sons Ltd.

To study the treatment outcome in patients with locally recurrent nasopharyngeal carcinoma (NPC) who were treated with stereotactic radiotherapy (SRT). Thirty patients with non-metastatic, locally recurrent NPC who were treated with curative intent between 1998 and 2002 were retrospectively analyzed. The International Union Against Cancer T-stage distribution at recurrence (rT) was as follows: rT1-14, rT2-7, rT3-3, and rT4-6. All patients were treated with SRT with a daily fractional dose of 2.5-4.5 Gy (median, 3 Gy) in 8-22 fractions (median, 18 fractions). Total equivalent dose (TED) was calculated by the linear-quadratic formula without a time factor correction. The 5-year actuarial overall survival rate, disease-specific survival rate, and local failure-free survival (LFFS) rate for the whole group were 40%, 41.4%, and 56.8%, respectively. The 3-year LFFS rates of rT1-2 and rT3-4 diseases were 65% and 66.7%, respectively. Seven of nine patients who received a TED <55 Gy recurred locally compared with 4 of 21 patients who received > or =55 Gy. Their corresponding 5-year LFFS rates were 22.2% and 75.8% (p = 0.005). The TED was the only factor significant in affecting the local control on univariate analyses. SRT is an effective treatment for locally recurrent NPC. TED > or =55 Gy should be given to secure a higher local control rate. The late complication rates were acceptable for patients with rT1-2 disease. For patients with rT3-4 disease, more works need to be done to further decrease the late complications.

To date, studies assessing the risk of post-transplant hepatocellular carcinoma (HCC) recurrence have focused on tumour characteristics. This study investigated the impact of donor characteristics and graft quality on post-transplant HCC recurrence. Using the Scientific Registry of Transplant Recipients patients with HCC who received a liver transplant between 2004 and 2011 were included, and post-transplant HCC recurrence was assessed. A multivariable competing risk regression model was fitted, adjusting for confounders such as recipient sex, age, tumour volume, α-fetoprotein, time on the waiting list and transplant centre. A total of 9724 liver transplant recipients were included. Patients receiving a graft procured from a donor older than 60 years (adjusted hazard ratio (HR) 1.38, 95 per cent c.i. 1.10 to 1.73; P = 0.006), a donor with a history of diabetes (adjusted HR 1.43, 1.11 to 1.83; P = 0.006) and a donor with a body mass index of 35 kg/m(2) or more (adjusted HR 1.36, 1.04 to 1.77; P = 0.023) had an increased rate of post-transplant HCC recurrence. In 3007 patients with documented steatosis, severe graft steatosis (more than 60 per cent) was also linked to an increased risk of recurrence (adjusted HR 1.65, 1.03 to 2.64; P = 0.037). Recipients of organs from donation after cardiac death donors with prolonged warm ischaemia had higher recurrence rates (adjusted HR 4.26, 1.20 to 15.1; P = 0.025). Donor-related factors such as donor age, body mass index, diabetes and steatosis are associated with an increased rate of HCC recurrence after liver transplantation. © 2015 BJS Society Ltd Published by John Wiley & Sons Ltd.

To evaluate the safety and efficacy of high-powered (80-100 W) percutaneous microwave ablation (MWA) at a frequency of 2450±10 MHz for treating larger hepatocellular carcinoma (HCC) and to predict the risk factors of local recurrence after high-powered MWA. The study was approved by the Institutional Review Board, and informed consent was waived because of the retrospective study design. Forty-five patients with a total of 60 lesions received high-power (80-100 W) MWA at a frequency of 2450±10 MHz through a percutaneous approach that was guided by ultrasound. Of the 60 lesions with a maximum tumour measuring 3-8 cm, 46 lesions were 3-5 cm and 14 were 5-8 cm. The complete ablation rates, local recurrence rates, complications, and short-term survival were analysed. Ten possible risk factors for local recurrence were analysed. The complete ablation rates were 82.61% for the first ablation and 100% for the second ablation for 3-5 cm lesions. The complete ablation rates were 64.29% (82.61% versus 64.29%, p=0.037) for the first ablation and 85.71% (100% versus 85.71%, p=0.055) for the second ablation for 5-8 cm lesions. Local recurrence was observed in 11 out of the 45 (24.44%) successfully treated patients. The 1-year and 2-year survival rates were 95.56% (43/45) and 86.67% (39/45), respectively. No procedure-related mortality was observed and no major bleeding, liver rupture, or liver abscesses occurred. Univariate analysis showed that a positive correlation existed between the number of lesions (p=0.022), proximity to the risk area (p=0.001), pre-ablation alpha-fetoprotein (AFP) levels (p=0.025), hepatitis B virus (HBV)-DNA replication (p=0.027) and local recurrence. Multivariate analysis identified HBV-DNA (p=0.031) and proximity to the risk area (p=0.039) as the independent prognosis factors causing postoperative HCC local recurrence. High-powered MWA of larger hepatocellular carcinomas appears to be a safe and effective treatment. HBV-DNA and proximity to the risk area appear to be independent predictors of local tumour recurrence. Copyright © 2015 The Royal College of Radiologists. Published by Elsevier Ltd.

Essentials The long-term risk of recurrence and death after distal deep vein thrombosis (DVT) is uncertain. We included subjects with first proximal or isolated distal DVT (IDDVT) and no pulmonary embolism. The risk of symptomatic and asymptomatic recurrence is lower after IDDVT (vs. proximal). IDDVT may be associated with a lower long-term risk of death, especially after unprovoked DVT. Background A few studies have focused on the risk of recurrence after first acute isolated distal deep vein thrombosis (IDDVT) compared with proximal DVT (PDVT), whereas the incremental risk of death has never been explored beyond the first 3 years after acute event. Methods Our single-center cohort study included patients with first symptomatic acute PDVT or IDDVT. Patients were excluded if they had concomitant pulmonary embolism (PE) or prior venous thromboembolism. The primary outcomes were symptomatic objectively diagnosed recurrent PDVT or PE and all-cause death. Results In total, 4759 records were screened and 831 subjects included: 202 had symptomatic IDDVT and 629 had PDVT. The median age was 66 years and 50.5% were women. A total of 125 patients had recurrent PDVT or PE during 3175 patient-years of follow-up: 109 events occurred after PDVT (17.3%) and 16 after IDDVT (7.9%). Annual recurrence rates were 4.5% (95% confidence interval [CI], 3.7-5.4%) and 2.0% (95% CI, 1.1-3.2%), respectively, for an adjusted hazard ratio (aHR) for IDDVT patients of 0.32 (95% CI, 0.19-0.55). Death occurred in 263 patients (31.6% [95% CI, 28.6-34.9%]) during 5469 patient-years of follow-up for an overall annual incidence rate of 4.8% (95% CI, 4.2-5.4%). The mortality rate was 33.5% (n = 211) in PDVT patients and 25.7% (n = 52) in IDDVT patients. The long-term hazard of death appeared lower for IDDVT patients (aHR, 0.75 [95% CI, 0.55-1.02]), especially after unprovoked events (aHR, 0.58 [95% CI, 0.26-1.31]). Conclusions Compared with PDVT, IDDVT patients were at a lower risk of recurrent VTE. The risk of death appeared lower after IDDVT during a median follow-up of 7.6 years. © 2017 International Society on Thrombosis and Haemostasis.

Chemical matricectomy with sodium hydroxide is a method being used successfully in the treatment of ingrown toenail. In this study, it was aimed to evaluate long-term recurrence rates after chemical matricectomy using sodium hydroxide application of different durations. Two hundred two patients with ingrown nail edges were treated with either 1-minute (Group 1) or 2-minute (Group 2) applications of sodium hydroxide matricectomy. All patients were followed for at least 2 years. Chemical matricectomy with sodium hydroxide was applied to a total of 585 nail edges of 202 cases. The overall recurrence rates in Group 1 and Group 2 were 6.4% and 7.1%, respectively, during the average 7.5-year follow-up period. No statistically significant differences were detected in terms of recurrence between the 2 groups (p = .73). Chemical matricectomy with sodium hydroxide is an easy method in the treatment of ingrown nails, with low morbidity and high success rates. There was no difference between 1-minute and 2-minute applications in terms of recurrence during the long-term follow-up. Chemical matricectomy with 1-minute application of sodium hydroxide showed high success in terms of long-term follow-up results.

Purpose: A retrospective evaluation was done of clinical utility of lung radiofrequency (RF) ablation in recurrent non-small-cell lung cancer (NSCLC) after surgical intervention. Methods: During May 2003 to October 2010, 44 consecutive patients (26 male and 18 female) received curative lung RF ablation for 51 recurrent NSCLC (mean diameter 1.7 {+-} 0.9 cm, range 0.6 to 4.0) after surgical intervention. Safety, tumor progression rate, overall survival, and recurrence-free survival were evaluated. Prognostic factors were evaluated in multivariate analysis. Results: A total of 55 lung RF sessions were performed. Pneumothorax requiring pluerosclerosis (n = 2) and surgical suture (n = 1)more » were the only grade 3 or 4 adverse events (5.5%, 3 of 55). During mean follow-up of 28.6 {+-} 20.3 months (range 1 to 98), local tumor progression was found in 5 patients (11.4%, 5 of 44). The 1-, 3-, and 5-year overall survival rates were 97.7, 72.9, and 55.7%, respectively. The 1- and 3-year recurrence-free survival rates were 76.7 and 41.1%, respectively. Tumor size and sex were independent significant prognostic factors in multivariate analysis. The 5-year survival rates were 73.3% in 18 women and 60.5% in 38 patients who had small tumors measuring {<=}3 cm. Conclusion: Our results suggest that lung RF ablation is a safe and useful therapeutic option for obtaining long-term survival in treated patients.« less

To compare (1) quality of life and (2) rate of recurrent small bowel obstructions (SBO) for patients treated with novel manual physiotherapy vs no treatment. One hundred and three subjects (age 19-89) with a history of recurrent adhesive SBO were treated with a manual physiotherapy called the Clear Passage Approach (CPA) which focused on decreasing adhesive crosslinking in abdominopelvic viscera. Pre- and post-therapy data measured recurring obstructions and quality of life, using a validated test sent 90 d after therapy. Results were compared to 136 untreated control subjects who underwent the same measurements for subjects who did not receive any therapy, which is the normal course for patients with recurring SBO. Comparison of the groups allowed us to assess changes when the physiotherapy was added as an adjunct treatment for patients with recurring SBO. Despite histories of more prior hospitalizations, obstructions, surgeries, and years impacted by bowel issues, the 103 CPA-treated subjects reported a significantly lower rate of repeat SBO than 136 untreated controls (total obstructions P = 0.0003; partial obstructions P = 0.0076). Subjects treated with the therapy demonstrated significant improvements in five of six total domains in the validated Small Bowel Obstruction Questionnaire (SBO-Q). Domains of diet, pain, gastrointestinal symptoms, quality of life (QOL) and pain severity when compared to post CPA treatment were significantly improved ( P < 0.0001). The medication domain was not changed in the CPA treated group ( P = 0.176). CPA physical therapy was effective for patients with adhesive SBO with significantly lower recurrence rate, improvement in reported symptoms and overall quality of life of subjects.

Overall survival in hepatocellular carcinoma patients treated with percutaneous radiofrequency ablation is influenced by both recurrence and successive treatments. We investigated post-recurrence survival after radiofrequency ablation. Data on 103 early/intermediate patients initially treated with radiofrequency ablation and followed for a median of 78 months (range 68-82) were retrospectively analysed. If intrahepatic disease recurrence occurred within or contiguous to the previously treated area it was defined as local, otherwise as distant; recurrence classified as Barcelona Clinic Liver Cancer stage C was defined by neoplastic portal vein thrombosis or metastases. A total of 103 patients were included (82.5% male; median age 70 years, range 39-86). During follow-up, 64 recurrences were observed. Median overall survival was 62 months (95% confidence interval: 54-78) and survival rates were 97%, 65% and 52% at 1, 4 and 5 years, respectively. Median post-recurrence survival was 22 months (95% confidence interval: 16-35). Child-Pugh score, performance status, sum of tumour diameters at recurrence and recurrence patterns were independent predictors of post-recurrence survival.

Preoperative chemoradiotherapy has been widely used for the prevention of local recurrence of locally advanced rectal cancer, and the effect of chemoradiotherapy is known to be associated with overall survival. We aimed to evaluate the association of the pathologic response grade with tumor recurrence rate after chemoradiotherapy, using radiographic analysis and the Response Evaluation Criteria in Solid Tumors as the parameters. This study was conducted at a single tertiary care institution in Japan. This was a retrospective cohort study of patients undergoing preoperative chemoradiotherapy. A total of 101 low rectal cancer patients receiving preoperative chemoradiotherapy from July 2004 to August 2012 were enrolled. The tumor reduction rate was measured with the use of traditional Response Evaluation Criteria in Solid Tumors, barium enema, and CT volumetry, and the correlation between the reduction rate and the pathologic response grade was examined. The tumor reduction rate assessed according to Response Evaluation Criteria in Solid Tumors showed no association with the pathologic response grade (p =0.61). In contrast, the radiographic response rate by both barium enema and CT volumetry strongly correlated with the pathologic response grade (p < 0.0001 and p = 0.001).In terms of local tumor recurrence, those diagnosed as high responders by the pathologic response grade, Response Evaluation Criteria in Solid Tumors, barium enema, and CT volumetry had a lower recurrence rate (p =0.03, p =0.03, p =0.0002, and p =0.001). The difference between high responders and low responders was especially prominent by barium enema and CT volumetry. The study is limited by its retrospective nature. Double-contrast barium enema and CT volumetry were superior to Response Evaluation Criteria in Solid Tumors in evaluating the effect of chemoradiotherapy and predicting the likelihood of tumor recurrence.

To evaluate the pharmacological effects of traditional Chinese medicine, bear bile capsule and Huangqi granule, on recurrent parotitis in children. In this prospective, controlled, and randomized study, a total of 151 young children were divided into three groups: Group A included massaging the children's parotid region and melting vitamin C in their mouth daily; Group B included swallowing bear bile capsule and Huangqi granule daily; and Group C included massages and vitamin C as prescribed in Group A, and traditional Chinese medicine as prescribed in Group B. Children were treated individually for one month and then a follow-up study was conducted for 1 to 3.5 years. Analysis of variance (ANOVA) and Ridit analysis were employed for statistical analysis. The recurrence rate decreased in every group, but was significantly more in Groups B and C when compared to Group A. The recurrences significantly decreased (P<0.01) in Group B and their recovery rate was as high as 63%, significantly better than those of the other groups (P<0.01). Huangqi and bear bile could be a novel clinical approach for treating recurrent parotitis in children.

The objective of this study was to determine the efficacy and safety of endoscopic submucosal dissection for locally recurrent colorectal cancer after previous endoscopic mucosal resection. A total of 16 patients with locally recurrent colorectal lesions were enrolled. A needle knife, an insulated-tip knife and a hook knife were used to resect the lesion along the submucosa. The rate of the curative resection, procedure time, and incidence of complications were evaluated. Of 16 lesions, 15 were completely resected with endoscopic submucosal dissection, yielding an en bloc resection rate of 93.8 percent. Histologic examination confirmed that lateral and basal margins were cancer-free in 14 patients (87.5 percent). The average procedure time was 87.2 +/- 60.7 minutes. None of the patients had immediate or delayed bleeding during or after endoscopic submucosal dissection. Perforation in one patient (6.3 percent) was the only complication and was managed conservatively. The mean follow-up period was 15.5 +/- 6.8 months; none of the patients experienced lesion residue or recurrence. Endoscopic submucosal dissection appears to be effective for locally recurrent colorectal cancer after previous endoscopic mucosal resection, making it possible to resect whole lesions and provide precise histologic information.

Recanalization of long segmental occlusions of femoropopliteal arteries can be achieved by angioplasty and implantation of nitinol stents with high procedural success rates. However, due to recurrent in-stent restenoses (ISR) some patients need repeated interventions and their intermediate success rates are uncertain. Patients who were treated in our center from March 2008 through February 2011 due to symptomatic ISR (as determined by Duplex sonography) were retrospectively included in the study. After endovascular treatment of their ISR, they were prospectively evaluated with regard to recurrent ISR of the target lesions. A total of 36 limbs (=lesions) in 32 patients (69% male, mean age 69±9 years) were successfully treated by balloon-angioplasty. Adjunctive cutting balloons and drug eluting balloons were used in 78% and 8%, respectively. Mean follow-up was 326 days. Recurrent ISR occurred in 10 (28%) lesions, while 26 (78%) lesions showed no recurrence of ISR. In a multivariate logistic regression analysis, age, gender, cardiovascular risk factors, renal failure and medication with cilostazol were not significantly associated with recurrent ISR. Moreover, the number of previous interventions of the target lesions was not an independent predictor of recurrent ISR. Patients with multiple recurrences of ISR seem to have the same prospects of acute and mid-term success for endovascular treatment as those with first presentation of ISR. However, this observation has to be confirmed by prospective, large scale studies with a longer follow-up period to determine the significance of endovascular intervention within the scope of different revascularization approaches for treatment of recurrent ISR.

Postoperative infectious complications increase disease recurrence in colorectal cancer patients. We herein investigated the impact of infectious complications on gastric cancer recurrence after curative surgery. In total, 502 patients who underwent R0 resection for gastric cancer were reviewed. Patients were classified into those with infectious complications (IC group) and those without infectious complications (NO group). The risk factors for recurrence-free survival (RFS) were identified. Infectious complications, which occurred in 52 patients (10.4%), included pneumonia, ileus with a systemic inflammatory reaction, anastomotic leakage, and intraperitoneal abscess. The overall 5-year RFS rate was 83% in the NO group and 58% in the IC group (p = 0.000). Multivariate analysis demonstrated that age, ASA score, stage, and infectious complications were significant predictors of RFS. Infectious complications were a risk factor for gastric cancer recurrence. To avoid causing infectious complications, the surgical procedure, surgical strategy, and perioperative care should be carefully planned.

Transanal endoscopic microsurgery: a New Zealand experience.

Transanal endoscopic microsurgery (TEMS) is a proven alternative therapy to either radical surgery or endoscopic mucosal resection for rectal neoplasms. It has proven benefits with lower morbidity and mortality compared with total mesorectal excision, and a lower local recurrence rate when compared to endoscopic mucosal techniques. A retrospective data collection of TEMS procedures performed through Waikato District Health Board, New Zealand, from 2010 to 2015 was conducted. Supportive follow-up data were sourced from patient records and from local centres around New Zealand. A total of 137 procedures were performed over the study period, with five being repeat procedures. Procedures were mostly performed for benign lesions (66.4%) with an overall complication rate of 15.3%, only five of which were Clavien-Dindo grade III (3.6%). Our local recurrence rate after resection of benign lesions was 5.1%. Our data set demonstrates the TEMS procedure to be safe compared to radical resection (total mesorectal excision) for sessile rectal lesions. Close endoscopic follow-up is recommended, especially for close or incomplete margins. Good therapeutic results can be obtained for appropriately selected early malignant lesions. TEMS provides better oncological results than endoscopic mucosal resection or transanal excision. © 2017 Royal Australasian College of Surgeons.

[Experience with Clotteau-Prémont's technique in abdominal wall hernias. Preliminary report].

Incisional hernias account for at least a third of abdominal wall hernias. There are different techniques of repair that include the use of prosthetic materials, which has lowered the hernia recurrence rate. Nonetheless, its use in case of rejection or infection requires other techniques with local tissue. The use of prosthetic material in a contaminated environment is contraindicated because the risk of infection and recurrence rate is unacceptably high. In order to compare two repair techniques for abdominal wall hernias in terms of complications and recurrence to be used as an alternative for hernia repair in patients with abdominal wall hernias, we conducted, between January 2000 and January 2004, an observational, longitudinal, retrospective, non-randomized matched control case study in patients with abdominal wall hernia. A total of 30 patients were studied and were divided into two groups of 15 patients each. Subjects were matched for sex, age and hernia type (group A, mesh treated and group B, Clotteau-Prémont treated) who had at least a 5-month postoperative follow-up. Complication and recurrence rate was assessed and compared. There were no differences between the two groups in complications or recurrence (p <0.05). The average follow-up time was 18.9 +/- 8 months for group A and 15 +/- 7.9 months for group B. Clotteau-Prémont's technique is a safe and feasible alternative procedure with indications in selected patients.

Local steroids have been used as an adjuvant therapy to patients undergoing internal urethrotomy (IU) in treating urethral strictures. Whether this technique is effective and safe is still controversial. The aim of this study is to determine the efficacy and safety of local steroids as applied with the IU procedure. A systematic review of the literature was performed by searching Medline, Embase, Cochrane Library Databases, and the Web of Science. We included only prospective randomized, controlled trials that compared the efficacy and safety between IU procedures with applied local steroids and those without. Eight studies were found eligible for further analysis. In total, 203 patients undergoing IU were treated with steroid injection or catheter lubrication. Time to recurrence is statistically significant (mean: 10.14 and 5.07 months, P<0.00001).The number of patients with recurrent stricture formation significantly decreased at different follow-up time points (P=0.05).No statistically significant differences were found between the recurrence rates, adverse effects, and success rates of second IUs in patients with applied local steroids and those without. The use of local steroids with IU seems to prolong time to stricture recurrence but does not seem to affect the high stricture recurrence rate following IU. When local steroids are applied with complementary intention, the disease control outcomes are encouraging. Further robust comparative effectiveness studies are now required.

Overweight and obesity are less closely associated with idiopathic intracranial hypertension (IIH) in young children than in post-pubescent children and adults. We examined the hypothesis that being overweight or obese (body mass index (BMI) ⩾ 85th percentile) in children is a risk factor for IIH recurrence. A total of 43 children with IIH who were followed up for an average of 9 ± 3.4 years were evaluated in a retrospective case-control series. The rate of IIH recurrence was compared between children of healthy weight and children presenting with overweight or obesity, using survival curve analysis. The overall risk for long-term IIH recurrence in children is ~20%. Following weight stratification, the risk for IIH recurrence in our cohort was fivefold higher in children with a BMI ⩾ 85th percentile (57%) than in healthy weight children (11%; log-rank test P = 0.04). Pediatricians may consider counseling families that weight control may be a means of decreasing the risk of IIH recurrence.

Are live birth rates (LBR) different after ART cycles between women with primary or recurrent endometrioma? Women with recurrent endometrioma have similar LBR as compared to patients with primary endometrioma. Recurrence rate can be as high as 29% after endometrioma excision. Prior studies on management of endometrioma before ART involve primary endometriomas. There is limited information regarding the prognosis of women with recurrent endometriomas. A multicenter retrospective cohort study, including 76 women with primary and 82 women with recurrent endometriomas treated at the participating centers over a 6-year period. Women with endometrioma who underwent ART at three academic ART centers. Couples with another indication for ART were excluded. Female age, median number of prior failed ART cycles, proportion of patients with bilateral endometrioma (28 versus 28.9%), ovarian stimulation protocols, and total gonadotropin consumption were similar between the study groups. Numbers of metaphase two oocytes (5 versus 6), number of embryos transferred, and the proportion of patients undergoing blastocyst transfer were similar across the study groups. Clinical pregnancy rates (36.6 versus 34.2%, absolute difference 2.4%, 95% CI: -12.5 to 17.3%, P = 0.83) and LBR (35.4 versus 30.3%, absolute difference 5.1%, 95% CI: -9.5 to 19.7%, P = 0.51) per started cycle in recurrent and primary endometrioma were similar. Comparable success rates were also confirmed with logistic regression analysis (OR: 1.14, 95% CI: 0.78-0.57, P = 2.3). The retrospective design has inherent limitations. Some women with severely decreased ovarian reserve after primary endometrioma excision may not have pursued further treatment. The management of endometrioma prior to ART is controversial but a different management strategy is not required for recurrent endometriomas. Since recurrent endometriomas do not have a worse impact on ART outcome than primary endometriomas, and repeat surgery has a higher risk for complications, conservative management without surgery can be justified.

Economic impact of the use of rifaximin 550 mg twice daily for the treatment of overt hepatic encephalopathy in Italy.

PubMed

Roggeri, Daniela Paola; Roggeri, Alessandro

2017-01-01

Hepatic encephalopathy (HE) is associated with a reduced survival, an increased risk of hospitalization for recurrences, and a reduced health-related quality of life. The purpose of the present economic analysis was to evaluate the impact on the Italian National Health Service (INHS) expenditure of the treatment with rifaximin 550 mg twice daily (Tixteller ® /Tixtar ® ) for the reduction of the recurrences of overt HE, with respect to the current treatment approach. Costs associated with patients treated with rifaximin 550 mg twice daily were estimated considering the reduction in hospitalizations for HE recurrences revealed by registrative clinical trial (-50%) applied to the hospitalization rate (42.5%) emerging from an Italian observational real-world study; costs associated with patients not treated with rifaximin were estimated based on the hospitalization rate, resulting from the same Italian observational study. Sensitivity analyses considering possible different discount levels to INHS structures for rifaximin were performed. The INHS perspective for a period of 3 years was considered. The treatment with rifaximin 550 mg twice daily, although increasing drug costs, is associated with a reduction in hospitalizations for HE recurrences that leads to an overall reduction of total costs charged to INHS, which could be estimated, based on the forecasted uptake of the treatment, at about €130,000 in the first year, reaching ~€260,000 in the third year. Considering a possible discount for rifaximin 550 mg to INHS structure of 20%, the total saving at the third year accounts for ~€3,000,000. Moreover, a relevant reduction in the number of hospitalizations and bed days is associated with rifaximin treatment. The treatment with rifaximin 550 mg twice daily, even if associated with an increase in drug expenditure, results in a reduction in total health care costs charged to INHS due to a reduction in hospitalizations for HE recurrences.

Burr-hole drainage has become the accepted treatment of choice for chronic subdural haematoma (cSDH), although still burdened with a major recurrence rate. The current analysis was initiated to determine management-related risk factors for recurrence, i.e. postoperative low-molecular-weight heparin thromboprophylaxis, and the importance of rinsing the subdural space. Two-hundred and forty-seven patients with computerised tomography (CT) defined symptomatic cSDH were managed by two burr-hole trepanations and drainage between January 2005 and November 2008. Postoperative thromboprophylaxis with 40 mg enoxaparine daily was given only during the first half of the study period. For the current analysis the amount of rinsing fluid, postoperative low-dose thromboprophylaxis, as well as age and gender, bilaterality, preoperative and postoperative blood coagulation studies, platelet counts and decrease of subdural fluid on early postoperative CT, were recorded and correlated with recurrence. Statistical calculation was done by univariate and multivariate analysis. A total of 62 of 247 patients needed revision surgery for recurrence (25.1 %). Recurrence rates were significantly lower in the patients treated without postoperative enoxaparine (18.84 %) than in the group with postoperative low-dose enoxaparine thromboprophylaxis (32.11 %) and enoxaparine was administered in a higher proportion of the patients suffering recurrence (P = 0.013). A median intraoperative irrigation volume of 863 ml saline was used in the patients suffering recurrence and 1,500 ml in patients without recurrence (P < 0.001). The median age was slightly higher in the patients suffering from recurrence. Male gender predominated in both groups but was slightly more pronounced in the recurrence group. Preoperative and postoperative platelet counts and plasmatic coagulation indices did not differ significantly between the groups. Relative residual subdural fluid collection on early postoperative CT remained larger in patients finally suffering recurrence (P = 0.03). Multivariate analysis confirmed a small amount of rinsing fluid, male gender and the use of enoxaparine as the most important risk factors for recurrence, although that latter factor did not reach statistical significance in the multivariate analysis. The investigation provides evidence that copious intraoperative irrigation and avoidance of postoperative low-molecular-weight heparin thromboprophylaxis may reduce the recurrence rate of cSDH.

It is widely accepted that the standard first-line treatment for most endocrine inactive pituitary macroadenomas (EIA) is surgery, usually via a transsphenoidal approach. What is less clear is what approach to take when these tumors recur, especially when this recurrence involves areas which are difficult to surgically remove tumor from, such as the suprasellar region or cavernous sinuses. We present long term follow-up for a series of 81 patients who underwent repeat surgery for recurrent non-secreting pituitary adenomas. We analyzed data collected from all adult patients undergoing their second microsurgical transsphenoidal resection of a histologically proven endocrine-inactive pituitary adenoma at the University of California at San Francisco between January 1970 and March 2001. Data for these patients were collected by review of medical records, mail, and/or telephone interviews. Visual function, anterior pituitary function, and tumor control rates were analyzed for the series. Records were available for a total of 81 recurrent EIA patients. The median time between their initial and repeat operations was 4.1 years. The mean tumor size was 2.2 ± 0.2 cm. A total of 35/81 patients had greater than 5 years of follow-up. A total of 24/81 patients had greater than 10 years of follow-up. Over one half of these patients presented with visual disturbance, and we found that 39% of these patients experienced improved vision with a second surgery. More importantly, no one with normal vision suffered any appreciable decline in vision. Approximately, 35% of patients with pre-operative anterior pituitary dysfunction recovered function after surgery in our series; and no patient’s function worsened. A total of 4/52 (8%) patients with greater than 2 years of post-op follow-up experienced a clinically meaningful tumor recurrence requiring additional treatment. Our data suggest that when performed by experienced transsphenoidal surgeons, durable tumor control can be obtained in these frequently locally aggressive tumors with acceptable rates of post-operative morbidity.

A systematic review of the cases documented in the literature regarding Pleomorphic hyalinizing angiectatic tumor of soft parts (PHAT) was performed in order to identify (1) location on presentation (2) surgical treatment modality (3) recurrence rate (4) any associations between location, age, histology, surgery type on recurrence. A systematic review of medical literature listed on PubMed was conducted identifying any prior case report and/or case series of diagnosed PHAT, with no exclusion based on language or time. Twenty-nine articles were identified removing any articles with duplicated cases yielding a total of 93 cases. Cases were broken down by gender, presenting location (UE/LE/axial), surgery type [wide local resection, non-wide local, wide local with radiation therapy (RT), non-wide local with RT], recurrence, and time to recurrence. The mean age at presentation was 54.5 ± 17.1 (range 10-89) with the 76% of cases appearing in the lower extremity (15% UE, 9% Axial). Of the 93 patients, 74 had a known surgical procedure, 31% WL, 40% NWL, 8% WL + RT, 1% NWL + RT. Of those treated surgically, 63 pts had documented follow-up and 18 (29%) had recurrence. A strong association was observed between surgery type and recurrence. Local recurrence was more common within the group undergoing NWLE in 52% (16/41) of cases (p = 0.002). Kaplan-Meier analysis showed an estimate mean time for recurrence of 43.87 months [95% confidence interval (CI) 24.52-63.22; and standard error (SE) 7.59] for the entire population. A trend was also seen toward males having a shorter disease-free survival than females (29.4 mos. vs. 69.5 mos.). No significant association seen between size, location, histology type and recurrence. PHAT has a characteristic presentation in the LE with a relatively high rate of local recurrence and slow-growing potential. Wide local excision appears to be superior in decreasing recurrence rates and a long-term follow-up period is needed.

Embolic strokes of undetermined source represent 20% of ischemic strokes and are associated with a high rate of recurrence. Anticoagulant treatment with rivaroxaban, an oral factor Xa inhibitor, may result in a lower risk of recurrent stroke than aspirin. We compared the efficacy and safety of rivaroxaban (at a daily dose of 15 mg) with aspirin (at a daily dose of 100 mg) for the prevention of recurrent stroke in patients with recent ischemic stroke that was presumed to be from cerebral embolism but without arterial stenosis, lacune, or an identified cardioembolic source. The primary efficacy outcome was the first recurrence of ischemic or hemorrhagic stroke or systemic embolism in a time-to-event analysis; the primary safety outcome was the rate of major bleeding. A total of 7213 participants were enrolled at 459 sites; 3609 patients were randomly assigned to receive rivaroxaban and 3604 to receive aspirin. Patients had been followed for a median of 11 months when the trial was terminated early because of a lack of benefit with regard to stroke risk and because of bleeding associated with rivaroxaban. The primary efficacy outcome occurred in 172 patients in the rivaroxaban group (annualized rate, 5.1%) and in 160 in the aspirin group (annualized rate, 4.8%) (hazard ratio, 1.07; 95% confidence interval [CI], 0.87 to 1.33; P=0.52). Recurrent ischemic stroke occurred in 158 patients in the rivaroxaban group (annualized rate, 4.7%) and in 156 in the aspirin group (annualized rate, 4.7%). Major bleeding occurred in 62 patients in the rivaroxaban group (annualized rate, 1.8%) and in 23 in the aspirin group (annualized rate, 0.7%) (hazard ratio, 2.72; 95% CI, 1.68 to 4.39; P<0.001). Rivaroxaban was not superior to aspirin with regard to the prevention of recurrent stroke after an initial embolic stroke of undetermined source and was associated with a higher risk of bleeding.

Though intraoperative nerve monitoring (IONM) during thyroid surgery has gained universal acceptance for localizing and identifying the recurrent laryngeal nerve (RLN), its role in reducing the rate of RLN injury remains controversial. In order to assess the effect of IONM during thyroid surgery, its value in reducing the incidence of RLN palsy was systematically evaluated. Studies were evaluated for inclusion in this analysis by researching PubMed, Embase, the Cochrane Central Register of Controlled Trials, and the references of included studies. The initial screening of article titles and abstracts was independently performed by five reviewers based on the research protocol criteria. Each article was then read in detail and discussed before inclusion in the meta-analysis. Data were independently extracted, including the level of evidence, number of at-risk nerves, allocation method, baseline equivalence between groups, definitions of transient and permanent vocal fold palsy, systematic application of electrodes, etc. The meta-analysis was then performed. Odds ratios were pooled using a random effects model. Five randomized clinical trials and 12 comparative trials evaluating 36,487 at-risk nerves were included. Statistically significant differences in terms of total recurrent laryngeal nerve palsy (3.37% with intraoperative nerve monitoring [IONM] vs. 3.76% without IONM [OR: 0.74; 95% confidence interval [CI]: 0.59-0.92]) and transient recurrent laryngeal nerve palsy (2.56% with IONM vs. 2.71% without IONM [OR: 0.80; 95% CI: 0.65-0.99]) were identified. The persistent incidence of recurrent laryngeal nerve palsy was 0.78% for IONM versus 0.96% for nerve identification alone (OR: 0.80; 95% CI: 0.62-1.03). Based on this meta-analysis, statistically significant differences were determined in terms of the incidences of total and transient recurrent laryngeal nerve palsy after using IONM versus recurrent laryngeal nerve identification alone during thyroidectomy. However, no statistically significant differences were identified regarding the incidence of persistent recurrent laryngeal nerve palsy between groups. Copyright © 2012. Published by Elsevier B.V.

A total of 57 eligible patients with a history of recurrent implantation failure underwent an endometrial biopsy in the luteal phase of the menstrual cycle in the month immediately preceding the embryo transfer cycle. The comparative group consisted of a retrospective cohort of 66 women with recurrent implantation failure but without endometrial biopsy. There were no significant differences between the intervention and control groups in terms of age, follicle-stimulating hormone (FSH), free androgen index, anti-Müllerian hormone, body mass index, the number of embryos transferred, and the number of embryo transfer cycles. The clinical pregnancy rate in the intervention group (53%) was significantly (p < 0.001) higher than that of the control group (15%). The only predictive factor was FSH. Women with FSH < or =10 IU/L had a pregnancy rate of 57.8%, significantly (p < 0.05) higher than that (20%) of women with FSH >10 IU/L. Women with a normal FSH are more likely to derive benefit from endometrial scratch.

Abstract The relationship between hepatitis B virus (HBV) and the prognosis of hepatocellular carcinoma (HCC) after surgery remains uncertain. A retrospective cohort study was performed to evaluate the impact of pre-S deletions, T1762/A1764, and A1896 mutations on prognosis of HCC after curative resection. A total of 113 patients with positive serum HBV DNA (>200 IU/mL) who had underwent curative resection of pathologically proven HCC were recruited to determine the risk factors affecting the prognosis. The median follow-up time was 36.5 months and recurrence was detected in 67 patients (59.3%). The cumulative recurrence rates and overall survival rates at 1-, 3-, and 5-year after curative resection were 18.0%, 49.7%, 70.3%, and 93.7%, 61.0%, 42.5%, respectively. Patients with pre-S deletions showed significantly higher recurrence rates compared with those with wild type infection (HR: 1.822, P = .018), but not related with a significantly poor survival (HR: 1.388, P = .235). Subgroup analysis indicated that the patients with type III deletion had significant higher tumor recurrence rates than other deletion types (HR: 2.211, 95% confidence intervals [CI]: 1.008–4.846, P = .048). Multivariate analysis revealed that pre-S deletion, tumor size >3 cm in diameter, and the presence of microvascular invasion were independent risk factors for tumor recurrence. HBV pre-S deletions were found to be clustered primarily in the 5′ end of pre-S2 region and were more often found between amino acids 120 and 142 of the pre-S2 domain. The domains most frequently potentially involved were the transactivator domain in pre-S2 and polymerized human serum albumin binding site. Our cohort showed that pre-S deletions at the time of resection could predict tumor recurrence in HCC patients after curative resection. PMID:29069001

Neoadjuvant chemoradiotherapy followed by an optimal surgery is the standard treatment for patients with locally advanced rectal cancer. FDG-PET/CT is commonly used as the modality for assessing the effect of chemoradiotherapy. The purpose of this study was to investigate whether PET/CT-based volumetry could contribute to the prediction of pathological complete response or prognosis after neoadjuvant chemoradiotherapy. This was a retrospective cohort study. This study was conducted at a single research center. Ninety-one consecutive patients with locally advanced rectal cancer were enrolled between January 2005 and December 2015. Patients underwent PET/CT before and after neoadjuvant chemoradiotherapy. Maximum standardized uptake value and total lesion glycolysis on PET/CT before and after neoadjuvant chemoradiotherapy were calculated using isocontour methods. Correlations between these variables and clinicopathological factors and prognosis were assessed. PET/CT-associated variables before chemoradiotherapy were not correlated with either clinicopathological factors or prognosis. Maximum standardized uptake value was associated with pathological complete response, but total lesion glycolysis was not. Maximum standardized uptake value correlated with ypT, whereas total lesion glycolysis correlated with both ypT and ypN. High total lesion glycolysis was associated with a considerably poorer prognosis; the 5-year recurrence rate was 65% and the 5-year mortality rate 42%, whereas in lesions with low total lesion glycolysis, these were 6% and 2%. On multivariate analysis, high total lesion glycolysis was an independent risk factor for recurrence (HR = 4.718; p = 0.04). The gain in fluoro-2-deoxy-D-glucose uptake may differ between scanners, thus the general applicability of this threshold should be validated. In patients with locally advanced rectal cancer, high total lesion glycolysis after neoadjuvant chemoradiotherapy is strongly associated with a worse prognosis. Total lesion glycolysis after chemoradiotherapy may be a promising preoperative predictor of recurrence and death. See Video Abstract at http://links.lww.com/DCR/A464.

Earthquake Clustering on Normal Faults: Insight from Rate-and-State Friction Models

Temporal variations in slip rate on normal faults have been recognized in Hawaii and the Basin and Range. The recurrence intervals of these slip transients range from 2 years on the flanks of Kilauea, Hawaii to 10 kyr timescale earthquake clustering on the Wasatch Fault in the eastern Basin and Range. In addition to these longer recurrence transients in the Basin and Range, recent GPS results there also suggest elevated deformation rate events with recurrence intervals of 2-4 years. These observations suggest that some active normal fault systems are dominated by slip behaviors that fall between the end-members of steady aseismic creep and periodic, purely elastic, seismic-cycle deformation. Recent studies propose that 200 year to 50 kyr timescale supercycles may control the magnitude, timing, and frequency of seismic-cycle earthquakes in subduction zones, where aseismic slip transients are known to play an important role in total deformation. Seismic cycle deformation of normal faults may be similarly influenced by its timing within long-period supercycles. We present numerical models (based on rate-and-state friction) of normal faults such as the Wasatch Fault showing that realistic rate-and-state parameter distributions along an extensional fault zone can give rise to earthquake clusters separated by 500 yr - 5 kyr periods of aseismic slip transients on some portions of the fault. The recurrence intervals of events within each earthquake cluster range from 200 to 400 years. Our results support the importance of stress and strain history as controls on a normal fault's present and future slip behavior and on the characteristics of its current seismic cycle. These models suggest that long- to medium-term fault slip history may influence the temporal distribution, recurrence interval, and earthquake magnitudes for a given normal fault segment.

Colchicine is effective for the treatment of recurrent pericarditis. However, conclusive data are lacking regarding the use of colchicine during a first attack of acute pericarditis and in the prevention of recurrent symptoms. In a multicenter, double-blind trial, eligible adults with acute pericarditis were randomly assigned to receive either colchicine (at a dose of 0.5 mg twice daily for 3 months for patients weighing >70 kg or 0.5 mg once daily for patients weighing ≤70 kg) or placebo in addition to conventional antiinflammatory therapy with aspirin or ibuprofen. The primary study outcome was incessant or recurrent pericarditis. A total of 240 patients were enrolled, and 120 were randomly assigned to each of the two study groups. The primary outcome occurred in 20 patients (16.7%) in the colchicine group and 45 patients (37.5%) in the placebo group (relative risk reduction in the colchicine group, 0.56; 95% confidence interval, 0.30 to 0.72; number needed to treat, 4; P<0.001). Colchicine reduced the rate of symptom persistence at 72 hours (19.2% vs. 40.0%, P=0.001), the number of recurrences per patient (0.21 vs. 0.52, P=0.001), and the hospitalization rate (5.0% vs. 14.2%, P=0.02). Colchicine also improved the remission rate at 1 week (85.0% vs. 58.3%, P<0.001). Overall adverse effects and rates of study-drug discontinuation were similar in the two study groups. No serious adverse events were observed. In patients with acute pericarditis, colchicine, when added to conventional antiinflammatory therapy, significantly reduced the rate of incessant or recurrent pericarditis.

Bacterial vaginosis is a condition of unknown etiology, associated with an imbalance of the normal vaginal microbiota, characterized by a high recurrence rate despite of classical therapy solutions. Probiotics are microorganisms, which taken in adequate amounts, are proven to bring health benefits in human and animal bodies, by re-establishing the normal flora at different levels. The present article studies the possibility of using probiotic treatment as an adjuvant therapy for nonspecific vaginosis and reducing its recurrence rate. We have evaluated the evolution of patients with bacterial vaginosis who received the classical antibiotic therapy and a probiotic product. The study group consisted of 173 non-pregnant, sexually active patients, 20-45 years old, with no additional health problems and no contraceptive undergoing treatment, which have been admitted to the department of Obstetrics and Gynecology of the Bucharest Emergency University Hospital between 1.01.2012-31.12.2012.The bacteriological evaluation was made on cervical and vaginal cultures. From a total of 173 patients, those who used probiotics oral capsules while taking an antibiotic had lower recurrence rates. More than a half of women who did not use any probiotic product had 3 or more relapse episodes per year. Vaginal capsules with probiotics have also proven to be useful in lowering the recurrence rate, but research is still needed. Probiotic products are proven to be a helpful adjuvant therapy for bacterial vaginosis, with no adverse outcomes.

To determine the long-term prognosis of hepatocellular carcinoma (HCC) after argon-helium cryoablation and identify the risk factors that predict metastasis and recurrence. A total of 156 patients with hepatitis B-related HCC less than 5 cm in diameter who underwent curative cryoablation were followed up prospectively for tumor metastasis and recurrence. Immunohistochemistry was used to analyze the expression of vascular endothelial growth factor (VEGF). HBV basal core promoter (BCP) and precore mutations were detected by DNA sequence analysis. Post-treatment prognostic factors influencing survival, tumor metastasis and recurrence were assessed by univariate and multivariate analyses. The variables included the expression of VEGF in HCC tissues, clinical and pathologic characteristics of patients, and HBV features (HBV DNA level, HBV genotype, BCP mutation). The median follow-up period of the 156 patients was 37 months (range 8-48 months). The 1-, 2-, and 3-year overall survival rates were 92, 82 and 64%, respectively. The 1-, 2-, and 3-year recurrence-free survival rates were 72, 56 and 43%, respectively. Eighty-five patients (54.5%) had tumor recurrence or metastasis. The multivariate analysis showed that Child-Pugh class and the expression of VEGF in HCC tissues could be used as independent prognostic factors for overall survival. Meanwhile, the expression of VEGF in HCC tissues and HBV BCP mutations were found to be independent prognostic factors for recurrence-free survival. Strong expression of VEGF in HCC tissues and HBV BCP mutations are important risk predictors for recurrence or metastasis of HCC smaller than 5 cm in diameter.

Hemangiopericytoma (HPC) in the central nervous system (CNS) is a rare disease with distinctive biological/clinical characteristics compared with meningioma. Cases of HPCs of the CNS were collected, and clinicopathological records were retrospectively reviewed and analyzed. Immunohistochemistry (IHC) for proliferative markers (Ki-67, PHH3) and STAT6 were performed. A total of 140 cases were collected, with mean follow-up of 77 months (median 58.8 months; range 0.53-540.5 months). 1-, 5-, 10-, and 20-year survival rates were 99.1, 94.0, 74.4, and 61.9 %, respectively. Thirty-nine patients (27.9 %) had recurrent disease. Mean and median times to recurrence were 62.9 and 47.3 months with 1-, 5-, 10-, and 20-year recurrence-free survival rates of 98.3, 78.3, 50.1, and 11.0 %, respectively. Thirteen patients (9.3 %) developed extracranial metastases. No adjuvant radiation therapy, higher histologic grades, failure of gross-total resection, and cases with gamma-knife surgery (GKS) were factors associated with shorter disease-free survival (log-rank test, p = 0.02, 0.00, 0.02, 0.00), among which high histologic grade and cases with GKS were significant in multivariable analysis. Strong nuclear STAT6 expression was noted in HPCs in 62 cases of HPCs (60/62, 96.8 %), whereas diffuse weak positivity was demonstrated in all meningioma cases. The survival rate in patients with HPC of the CNS is comparable to that of previously reported series. Recurrence remains a critical clinical issue of the disease. Identification of NAB2-STAT6 fusion transcript with surrogate IHC marker is a valuable diagnostic tool in the differential diagnosis of the disease.

Evaluate whether radiotherapy (RT) after the neurosurgical treatment of atypical meningiomas (AM) has an impact on the reduction rate of recurrence. A Medline search through October 2017 using "atypical meningioma" returned 1277 papers for initial review. Inclusion criteria were as follows. We analyzed the database and included articles in which the anatomic pathological classification of atypical meningiomas was in accordance with WHO 2007 or WHO 2016 criteria, patients > 18 years of age, and there was postoperative external beam radiation to the tumor bed. Exclusion criteria were WHO grade I or III meningioma, patients who underwent whole-brain radiation, RT used as salvage therapy for recurrence, palliative dose of RT (< 45 Gy), recurrent AMs, and multiple AMs. Papers reporting outcomes in which atypical and anaplastic meningiomas were analyzed together were rejected, as were papers with small samples that may compromise evaluation. After filtering our initial selection, only 17 papers were selected. After reviewing the seventeen articles including a total of 1761 patients (972 female and 799 male; 1.21 female/1.0 male), the difference in proportion of tumor recurrence between patients with and without radiotherapy after neurosurgical procedure was 1.0448, 95% CI [0.8318 to 1.3125], p value = 0.7062. On the basis of this review, there is no evidence to suggest that RT decreases the rate of recurrence in patients with atypical meningiomas.

Local recurrence rates in operable rectal cancer are improved by radiotherapy (with or without chemotherapy) and surgical techniques such as total mesorectal excision. However, the contributions of surgery and radiotherapy to outcomes are unclear. We assessed the effect of the involvement of the circumferential resection margin and the plane of surgery achieved. In this prospective study, the plane of surgery achieved and the involvement of the circumferential resection margin were assessed by local pathologists, using a standard pathological protocol in 1156 patients with operable rectal cancer from the CR07 and NCIC-CTG CO16 trial, which compared short-course (5 days) preoperative radiotherapy and selective postoperative chemoradiotherapy, between March, 1998, and August, 2005. All analyses were by intention to treat. This trial is registered, number ISRCTN 28785842. 128 patients (11%) had involvement of the circumferential resection margin, and the plane of surgery achieved was classified as good (mesorectal) in 604 (52%), intermediate (intramesorectal) in 398 (34%), and poor (muscularis propria plane) in 154 (13%). We found that both a negative circumferential resection margin and a superior plane of surgery achieved were associated with low local recurrence rates. Hazard ratio (HR) was 0.32 (95% CI 0.16-0.63, p=0.0011) with 3-year local recurrence rates of 6% (5-8%) and 17% (10-26%) for patients who were negative and positive for circumferential resection margin, respectively. For plane of surgery achieved, HRs for mesorectal and intramesorectal groups compared with the muscularis propria group were 0.32 (0.16-0.64) and 0.48 (0.25-0.93), respectively. At 3 years, the estimated local recurrence rates were 4% (3-6%) for mesorectal, 7% (5-11%) for intramesorectal, and 13% (8-21%) for muscularis propria groups. The benefit of short-course preoperative radiotherapy did not differ in the three plane of surgery groups (p=0.30 for trend). Patients in the short-course preoperative radiotherapy group who had a resection in the mesorectal plane had a 3-year local recurrence rate of only 1%. In rectal cancer, the plane of surgery achieved is an important prognostic factor for local recurrence. Short-course preoperative radiotherapy reduced the rate of local recurrence for all three plane of surgery groups, almost abolishing local recurrence in short-course preoperative radiotherapy patients who had a resection in the mesorectal plane. The plane of surgery achieved should therefore be assessed and reported routinely.

Recurrence and reflux are 2 most important remote complications of lap-paraesophageal hernia (PEH) repair. However, the extent of recurrence remains unknown. We sought to determine the true incidence of recurrence after lap-PEH repair. A meta-analysis was carried out. PubMed, EMBASE, Cochrane Library, hand search, and personal communication were used to access and appraise studies. The inclusion criteria were full-text papers published from 1991 to date that describe lap-PEH repair in >25 patients, have at least a 6-month follow-up, and address the issue of recurrence. "Wrap migration" papers were excluded. Papers were appraised and the data were isolated on summary sheets. MS Office Excel 2003 was used to plot the results and represent it in graphs. Thirteen studies were eligible (all retrospective case series). A total of 965 patients with 99 recurrences were noted. The overall recurrence rate (in all patients) was 10.2% and was 14% if only the followed up patients (n=658/965) were considered. However, when patients with objective evidence (follow-up Ba esophagogram) were used (301/965), the "true" recurrence rate was 25.5% (ie, 1 in 4 recurred). The learning curve did not appear to be an issue (P=0.27). The studies revealed broad 95 CI and touched the line-of-no-effect, thereby increasing the "chance factor." When an alternate model was applied, esophageal lengthening (by Collis-Nissen gastroplasty) revealed a significant protective influence (P<0.0001). The true incidence of lap-PEH recurrence is 25.5%. The learning curve is not an adequate explanation. Mandatory (protocol) follow-up esophagograms at 1 year are essential. Two emphasis points in the repair have emerged: hiatoplasty and (superadded) esophageal lengthening.

Purpose: Our practice policy has been to provide intraoperative radiotherapy (IORT) at resection to patients with head-and-neck malignancies considered to be at high risk of recurrence. The purpose of the present study was to review our experience with the use of IORT for primary or recurrent cancer of the parotid gland. Methods and Materials: Between 1982 and 2007, 96 patients were treated with gross total resection and IORT for primary or recurrent cancer of the parotid gland. The median age was 62.9 years (range, 14.3-88.1). Of the 96 patients, 33 had previously undergone external beam radiotherapy as a component ofmore » definitive therapy. Also, 34 patients had positive margins after surgery, and 40 had perineural invasion. IORT was administered as a single fraction of 15 or 20 Gy with 4-6-MeV electrons. The median follow-up period was 5.6 years. Results: Only 1 patient experienced local recurrence, 19 developed regional recurrence, and 12 distant recurrence. The recurrence-free survival rate at 1, 3, and 5 years was 82.0%, 68.5%, and 65.2%, respectively. The 1-, 3-, and 5-year overall survival rate after surgery and IORT was 88.4%, 66.1%, and 56.2%, respectively. No perioperative fatalities occurred. Complications developed in 26 patients and included vascular complications in 7, trismus in 6, fistulas in 4, radiation osteonecrosis in 4, flap necrosis in 2, wound dehiscence in 2, and neuropathy in 1. Of these 26 patients, 12 had recurrent disease, and 8 had undergone external beam radiotherapy before IORT. Conclusions: IORT results in effective local disease control at acceptable levels of toxicity and should be considered for patients with primary or recurrent cancer of the parotid gland.« less

To develop a risk scoring system (RSS) for predicting recurrence in women with borderline ovarian tumours (BOTs). Cohort study of women with BOTs. French multicentre tertiary care centres. A cohort of 360 women with BOTs who received primary surgical treatment between January 2000 and December 2013. Clinical and pathological factors affecting recurrence in women with BOTs. The development of a model for the prediction of recurrence in women with BOTs. Overall the recurrence rate was 20.0% (72/360). Recurrence was associated with five variables: age < 45 years; preoperative serum tumour marker CA125 > 150 IU/mL; a serous histological subtype; International Federation of Gynecology and Obstetrics (FIGO) stage other than IA; and ovarian surgery other than bilateral salpingo-oophorectomy (BSO; i.e. cystectomy and unilateral salpingo-oophorectomy). These variables were included in the RSS and assigned scores ranging from 0 to 6. The discrimination of the RSS was 0.82 (95% confidence interval, 95% CI 0.79-0.85). A total score of 8 points corresponded to the optimal threshold of the RSS, with a rate of recurrence of 11.8% (35/297) and 58.7% (37/63) for women at low risk (<8 points) and women at high risk (≥8 points), respectively. The diagnostic accuracy was 85.0%. This study shows that the risk of BOT recurrence can be accurately predicted so that women at high risk can benefit from adapted surgical treatment. Our RSS permitted women with BOTs at low risk to be distinguished from women with BOTs at high risk of recurrence. © 2017 Royal College of Obstetricians and Gynaecologists.

Management and Prevention of Recurrent Clostridium Difficile Infection in Patients After Total Joint Arthroplasty

Clostridium difficile infection (CDI) is the most common infectious cause of nosocomial diarrhea in elderly patients, accounting for 15% to 25% of all cases of antibiotic-induced diarrhea in those patients. Virulent forms of this organism have developed, increasing the associated morbidity, mortality, and complication rates. The average patient undergoing total joint arthroplasty is at particular risk of CDI because of advanced age, the use of prophylactic antibiotic coverage in the perioperative period, multiple comorbid conditions, and length of hospital stay. In addition, patients who have had one CDI are at risk of another; the rate of recurrent CDI (RCDI) is 15% to 30%. To review the available information on RCDI, we conducted an extensive literature search, focusing on its epidemiology and the management strategies for its treatment and prevention. We found the management of RCDI is a controversial topic, with as yet no consensus regarding specific treatment guidelines. Several experienced clinicians have published suggested treatment algorithms, but they are based on anecdotal experience. With regard to the prevention of RCDI, the literature is scarce, and currently, the only effective strategies remain judicious use of perioperative antibiotics and appropriate implementation of infection control procedures. There are several vaccination medications that are currently being studied but are not yet ready for clinical use. We agree with the approach to management of RCDI that has been proposed in several articles, that is, on confirmation of a first recurrence of CDI by a stool toxin assay and clinical symptoms, a 14-day course of metronidazole or vancomycin; for a second recurrence, a tapered-pulsed course of vancomycin; and, for 3 or more recurrences, a repeat course of the tapered-pulsed vancomycin and adjunctive Saccharomyces boulardii or cholestyramine.

To review all available data published on central giant cell lesion (CGCL) of the jaws into a comprehensive analysis of its clinical/radiological features, with emphasis on the predictive factors associated with its recurrence. An electronic search was undertaken in 5 databases (February/2018), looking for reporting cases of CGCLs. A total of 365 publications were included, comprising 2270 lesions. CGCLs were more prevalent in women and the mandible. Cortical bone perforation occurred in 50% of the cases. Marginal/segmental resection was more often performed in larger lesions, and drug therapy was more frequent in small lesions. Recurrence was reported in 232 of 1316 cases (17.6%). The recurrence rate of the aggressive lesions (22.8%) after surgical treatment was higher than non-aggressive lesions (7.8%). Four of 5 CGCLs showed partial/total regression with pharmacological treatment. Aggressive lesions showed a worse response to corticosteroids than non-aggressive lesions. For the lesions submitted to surgery as the first treatment, curettage, enucleation, or marginal resection in relation to segmental resection, aggressive lesions, cortical bone perforation, and tooth root resorption were associated with increased recurrence rate. Recurrence related to a combination of surgical/pharmacological treatment could not be evaluated due to the variety of protocols. Aggressive CGCLs recur more often than the non-aggressive ones. Despite sometimes showing poor response to corticosteroid injection or surgical curettage, a combination of both treatment strategies should be considered in aggressive cases to reduce morbidities associated with radical surgery. The best protocol to manage aggressive and non-aggressive lesions remains to be determined. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Background A post-marketing surveillance (PMS) study was conducted with a 1-year observation period to assess the safety and efficacy of lamotrigine in routine clinical practice in patients with bipolar disorder (BD). Patients and methods Central enrollment method was used to recruit patients diagnosed with BD who were being treated for the first time with lamotrigine to prevent the recurrence/relapse of BD mood episodes. Adverse drug reactions (ADRs) and recurrence/relapse were assessed. Improvement of mania and depression was also assessed using the Hamilton’s Rating Scale for Depression (HAM-D) and the Young Mania Rating Scale (YMRS) at treatment initiation, 4–6 months post treatment initiation, and 10–12 months post treatment initiation. Results A total of 237/989 patients (24.0%) reported ADRs, most commonly rash (9.1%), and the incidence of serious ADRs was 3.3% (33/989 patients). Skin disorders occurred in 130 patients (13.1%), mostly within 8 weeks post treatment. A total of 237/703 patients (33.7%) experienced recurrence/relapse of mood episodes. The 25th percentile of the time to recurrence/relapse of mood episodes was 105 days. Remission of depression symptoms (HAM-D ≤7) occurred in 147/697 patients (21.1%) at treatment initiation, rising to 361 patients (67.4%) at 10–12 months post treatment. Remission of manic symptoms (YMRS ≤13) occurred in 615/676 patients (91.0%) at treatment initiation, rising to 500 patients (97.3%) at 10–12 months post treatment. Conclusion The results of this PMS study suggest that lamotrigine is a well-tolerated and effective drug for preventing recurrence/relapse of BD in clinical practice. PMID:28652744

The present study investigated the therapeutic effect of radiofrequency ablation on children with supraventricular tachycardia (SVT), and explored the risk factors for postoperative recurrence. A total of 312 patients with pediatric SVT were selected in the Affiliated Children's Hospital of Xuzhou Medical University from April, 2011 to March, 2017. All the patients were subjected to radiofrequency ablation, and clinical data were retrospectively analyzed. Tilt table test was performed before and after treatment, and heart rate, systolic and diastolic blood pressure before and after treatment were compared. Plasma levels of D-dimer (D-D), platelet α-granule membrane protein (GMP-140) and thrombin-antithrombin III complex (TAT) were detected by enzyme-linked immunosorbent assay before treatment, immediately after radiofrequency oblation, and at 1, 3 and 7 days after treatment. Treatment outcomes were compared between the atrioventricular reentrant tachycardia (AVRT) and atrioventricular nodal reentrant tachycardia (AVNRT) groups. Risk factors for postoperative recurrence were analyzed. Supine position heart rate after treatment was not significantly different from that before treatment (P>0.05), while the upright position heart rate was significantly increased after treatment (P<0.05). Systolic pressures of the supine and upright positions were significantly reduced after treatment compared with the levels before (P<0.05), but no significant differences were found in diastolic blood pressure of supine and the upright position (P>0.05). No significant difference in radiofrequency ablation rate, recurrence rate and incidence of complications were found between the AVRT and AVNRT groups (P>0.05). After radiofrequency, the levels of D-D, GMP-140 and TAT ablation showed an upward trend, but decreased at day 7 to reach preoperative levels. Logistic regression analysis revealed that residual slow pathway (OR=6.718, P=0.005) and inaccurate targeting (OR=2.815, P=0.007) were independent risk factors for postoperative recurrence (P<0.05). Although radiofrequency ablation can damage the cardiac vagal nerve, resulting in an increase in the heart rate after ablation during the course of the tilt table test and changed hemagglutination state within one week after ablation, those changes returned to normal after one week. The efficacy of radiofrequency ablation in the treatment of pediatric SVT is clear, and recurrence rate is low. Residual slow pathway and inaccurate targeting were independent risk factors for postoperative recurrence. PMID:29725383

It is likely that some patients whose tumor burdens exceed the current transplant criteria have favorable tumor biology, and that these patients would have low risk of tumor recurrence after liver transplantation (LT). To assess the rate of tumor growth as selection criteria for LT in patients with hepatocellular carcinoma (HCC). We identified all patients who underwent LT for HCC in our institution from 2002 to 2008. Total tumor volume (TTV) was calculated as the sum of the volumes of all tumors on pretransplantation imaging [(4/3)πr3, where r is the maximum radius of each HCC]. The rate of tumor growth was calculated as per-month change in TTV on sequential pretransplantation imaging before any locoregional therapy. A Kaplan-Meier plot was constructed and Cox regression analysis performed. Ninety-two patients were included in the study. The median follow-up was 19.5 (range 10.7-30.7) months during which 12 patients (13%) experienced recurrence of HCC. Twenty-four patients (26%) had HCC beyond the Milan criteria, and the overall survival rate of the entire group was 72%. Higher pre-LT alpha-fetoprotein (hazard ratio [HR] 1.01; P=.001), poorly differentiated tumors (HR 13; P=.039), the presence of microvascular invasion (HR 7.9; P=.001), higher TTV (HR 1.03; P<.001), and faster tumor growth (HR 1.09; P<.001) were significantly associated with the risk of recurrence. A cutoff value of tumor growth of 1.61 cm3/mo was chosen on the basis of the risk of recurrence with the use of a receiver operating characteristic curve. Patients beyond the Milan criteria with tumor growth<1.61 cm3/mo experienced less recurrence (11% vs 58%; P=.023) than those beyond the Milan criteria with tumor growth>1.61 cm3/mo. Similarly, rate of tumor growth predicted HCC recurrence in those beyond the University of California of San Francisco (UCSF) criteria. Patients with slowly growing tumor who would be currently excluded from LT because tumor burden exceeds traditional Milan and UCSF criteria may have a favorable posttransplantation outcome.

Purpose To investigate whether lymphatic microvessel density (LMVD) could be used as a predictive marker for the recurrence time of pterygia. Methods This was a prospective case series study. Ninety-six patients with unilateral eye primary nasal pterygia were included. The patients were clinically evaluated to grade the severity of their pterygia (32 were Grade 1, 29 were Grade 2, and 35 were Grade 3) before they underwent bare sclera resection with the use of mitomycin C. Excised tissues from the 96 patients and the ten normal nasal conjunctiva obtained from age-matched donor eyeballs (controls) were immunostained with LYVE-1 and CD31 monoclonal antibodies to evaluate LMVD and blood microvessel density (BMVD). The patients were followed up for three years or until pterygium recurrence was identified, which was defined as fibrovascular regrowth past the limbus in a previously compromised area. The recurrence time (RT) for a pterygium was calculated, and its relationship with LMVD and/or BMVD was statistically analyzed. Results In total, there were 24 cases of pterygium recurrence. The recurrence rate of Grade 1 was 28.1% (9/32), Grade 2 was 24.1% (7/29), and Grade 3 was 22.9% (8/35), as classified in the primary pterygium (p>0.05); the overall recurrence rate was 25% (24/96) for all patients during the three-year follow-up. In the tissue analysis, there were a small number of CD31 (+), LYVE-1(-) BMVD and only a few CD31 (weak), LYVE-1(+) LMVD in the ten normal nasal conjunctiva tissues. BMVD and LMVD increased significantly in the pterygium tissue compared to the control tissue and were significantly correlated with the width and area of pterygium in Grades 1–3 (all p values <0.05). RT was not correlated with BMVD or pterygium grade, but LMVD was significantly and negatively correlated with RT within each group and in the total patient cohort. Furthermore, we determined that an LMVD greater than 20 in the surgical specimens predicted pterygium recurrence. Conclusions The LMVD of surgical specimens is an independent risk factor and a valuable predictive factor for the recurrence time of pterygia. PMID:23378730

To assess choroidal inflammation-related circulatory changes associated with the anterior recurrence of Vogt-Koyanagi-Harada (VKH) disease, using indocyanine green angiography (ICGA) and laser speckle flowgraphy (LSFG). This retrospective case series included 17 eyes of 11 patients with VKH disease showing recurrent inflammatory findings in the anterior, but not posterior, segment (i.e. anterior recurrence). Indocyanine green angiography (ICGA) and LSFG were performed at the time of recurrence and one month after the initiation of corticosteroid therapy. The number and total area of hypofluorescent dark dots (HDDs) on ICGA were independently counted by three physicians and measured with ImageJ, respectively. Mean blur rate (MBR), a quantitative index of relative blood flow velocity, was calculated via the LSFG Analyzer software. Hypofluorescent dark dots (HDDs) were identified on ICGA in 13 of 17 eyes (76%) with the anterior recurrence of VKH disease. The number and total area of HDDs significantly decreased from 203 ± 101 dots to 59 ± 51 dots and from 48 789 ± 24 251 pixels to 15 664 ± 13 254 pixels, respectively. The change ratio of MBR significantly increased by 17.9 ± 16.3% after the treatment. Importantly, there was no significant association between the change ratios of HDDs and MBR. These findings on LSFG and ICGA clearly demonstrated subclinical involvement as well as post-treatment improvement of choroidal circulation impairment due to granulomatous inflammation in eyes with the anterior recurrence of VKH disease. The present data suggest the validity of using these two examinations, capable of detecting different circulatory changes, in the management of recurrent VKH disease. © 2016 Acta Ophthalmologica Scandinavica Foundation.

Complex ventral hernias remain a challenge for general surgeons despite advances in minimally invasive surgical techniques. This study compares outcomes following Rives-Stoppa (RS) repair, components separation technique with mesh (CST-M) or without mesh (CST), and endoscopic components separation technique (ECST). A retrospective review of patients undergoing open ventral hernia repair between 2006 and 2011 was performed. Analysis included patient demographics, surgical site occurrences, hernia recurrence, hospital readmission, and mortality. The search was limited to open repairs, specifically the RS, CST-M, CST, and ECST with mesh techniques. A total of 362 patients underwent repair with RS (66), CST-M (126), CST (117), or ECST (53). The groups were demographically similar. ECST was more frequently used for patients with a history of two or more recurrences (P < 0.001). The RS method had the lowest rate of recurrence (9.1%) compared with CST and CST-M with 28 and 25 per cent recurrences, respectively (P = 0.011). The RS recurrence rate was not significantly different than ECST (15%). There were no significant differences between groups for surgical site occurrences (P = 0.305), hospital readmission (P = 0.288), or death (P = 0.197). When components separation is necessary for complex ventral hernia repair, ECST is a viable option without added morbidity or mortality.

Spinal osteoid osteomas are benign primary tumors arising predominantly from the posterior column of the spine. These "osteoblastic" lesions have traditionally been treated with intralesional excision. The purpose of the present study was to review the treatment and local recurrence rates for symptomatic spinal osteoid osteomas. Multicenter ambispective cross-sectional observational cohort study. During the study period, a total of 84 patients (65 males, 19 females) were diagnosed with a spinal osteoid osteoma and received surgical treatment. The mean age at surgery was 21.8 ± 9.0 years (range: 6.7-52.4 years) and the mean follow-up was 2.7 years (13 days-14.5 years). Local recurrence, perioperative morbidity, and cross-sectional survival. Using the AOSpine Knowledge Forum Tumor multicenter ambispective database, surgically treated osteoid osteoma cases were identified. Patient demographic, clinical and diagnostic, treatment, local recurrence, perioperative morbidity, and cross-sectional survival data were collected and retrieved. Descriptive statistics were summarized using mean/standard deviation or frequency/percentage. In our study, most of the tumors were localized in the mobile spine (81 of 84 [96%]); all patients reported pain as a symptom. According to the postoperative assessment, 10 (12%) patients received an en bloc resection with marginal or wide margins, whereas two (2%) patients received en bloc resections with intralesional margins, 69 (82%) patients were treated by piecemeal "intralesional" resection, and three (4%) patients were not assessed. A total of six patients (7%) experienced a local recurrence, all of which occurred in patients who had received an intralesional resection. Benign bone-forming tumors of the spine are uncommon. Most patients in our series underwent a piecemeal resection with intralesional margins. This remains safe with a low local recurrence rate. En bloc excision may provide more chance of complete excision of the nidus but is not mandatory. The importance of complete excision of the nidus cannot be overemphasized.

Background/aim: Colorectal adenomatous polyps are precursors of colorectal cancer (CRC), which can be prevented with surveillance colonoscopy. This study aimed to assess risk factors for the recurrence of colorectal polyps and CRC following polypectomy. Materials and methods: In this single-center trial, a total of 510 patients who applied to the endoscopy unit of Hacettepe University Hospital for various reasons and who were diagnosed with at least one colorectal adenomatous polyp between 2000 and 2010 were retrospectively analyzed. Patients with colorectal adenomatous polyps or CRC recurrences were examined in terms of clinical and histological risk factors. Results: A total of 190 (37.1%) patients had surveillance colonoscopy. Among them, 127 (66.3%) were found to have polyp recurrence. Of the parameters defined for polyp recurrence, no association was found between the number of polyps (1-2, ≥3) (1-3, ≥4) in the first colonoscopy and diabetes mellitus, hypertension, hyperlipidemia, sex, family history of colon malignancy, smoking, alcohol usage, size of polyp (<10 mm, ≥10 mm), or advanced histologic type of polyp. The only significant difference was observed in patients who had left-sided colon polyps. In the basal colonoscopy, 130 patients had been diagnosed with CRC, and a significant correlation was found between the number of polyps (1, ≥2) and polyp size (≥10 mm), anemia, high sedimentation rate (>25), and CRC. In the first surveillance colonoscopy, CRC was detected in 12 patients. There was a significant correlation between the development of CRC and advanced histological type, anemia with high erythrocyte sedimentation rate, polyp size (<10 mm, ≥10 mm), and the number of polyps (<3, ≥3). Conclusion: Patients with left-sided colon polyps had a high risk of developing colorectal polyp recurrence. Moreover, the risk of developing CRC increased in patients who had advanced histology, a polyp larger than 10 mm, or more than three polyps.

Background Spontaneous pneumothorax is a major and frequently recurrent complication of lymphangioleiomyomatosis (LAM). Despite the customary use of pleurodesis to manage pnenumothorax, the recurrence rate remains high, and accompanying pleural adhesions cause serious bleeding during subsequent lung transplantation. Therefore, we have developed a technique of total pleural covering (TPC) for LAM to wrap the entire visceral pleura with sheets of oxidized regenerated cellulose (ORC) mesh, thereby reinforcing the affected visceral pleura and preventing recurrence. Methods Since January 2003, TPC has been applied during video-assisted thoracoscopic surgery for the treatment of LAM. The medical records of LAM patients who had TPC since that time and until August 2014 are reviewed. Results TPC was performed in 43 LAM patients (54 hemithoraces), 11 of whom required TPC bilaterally. Pneumothorax recurred in 14 hemithoraces (25.9%) from 11 patients (25.6%) after TPC. Kaplan-Meier estimates of recurrence-free hemithorax were 80.8% at 2.5 years, 71.7% at 5 years, 71.7% at 7.5 years, and 61.4% at 9 years. The recurrence-free probability was significantly better when 10 or more sheets of ORC mesh were utilized for TPC (P = 0.0018). TPC significantly reduced the frequency of pneumothorax: 0.544 ± 0.606 episode/month (mean ± SD) before TPC vs. 0.008 ± 0.019 after TPC (P<0.0001). Grade IIIa postoperative complications were found in 13 TPC surgeries (24.1%). Conclusions TPC successfully prevented the recurrence of pneumothorax in LAM, was minimally invasive and rarely caused restrictive ventilatory impairment. PMID:27658250

Human brucellosis and recurrent brucellosis is an ever-increasing public health concern, especially in endemic areas like Iran. Nevertheless, little is known regarding the epidemiology and determinants of recurrent brucellosis. Therefore, the objective of this study was to investigate epidemiological patterns and potential determinants of recurrent brucellosis in Hamadan Province during the years 2009-2015. Data on reported cases of new and recurrent brucellosis from 2009 to 2015 were obtained from the provincial Notifiable Diseases Surveillance System at Hamadan University of Medical Sciences. Incidence rates per 100000 were estimated at the county level. Binary logistic regression was used to estimate the effects of background characteristics and recurrent brucellosis. The power of discrimination of the model for recurrent brucellosis was assessed using the area under the curve (AUC). Among 7318 brucellosis cases, the total frequency (%) of recurrent cases was 472 (6.45%). The rate of recurrent brucellosis was higher in females, people aged 50 years and over, people with a history of consuming unpasteurized dairy products with no history of contact with animals, and in the winter season. Multivariable logistic regression analysis showed that female sex (adjusted odds ratio (AOR) 1.36, 95% confidence interval (CI) 1.13-1.65), age ≥55 years (AOR 4.15, 95% CI 2.32-7.42), consumption of unpasteurized dairy products (AOR 1.16, 95% CI 0.96-1.40), and winter season (AOR 1.32, 95% CI 1.03-1.71) are potential risk factors for recurrent brucellosis. The final model that involved all the determinants showed moderate discrimination (AUC 0.61). Female sex, older age, and winter months were found to be significant determinants of recurrent human brucellosis. Enhanced surveillance systems with an emphasis on these population characteristics will allow effective preventive and protective measures to be implemented and might alleviate the recurrence of brucellosis in the country.

Investigations regarding the impact of tumor biology after surgical management of colorectal liver metastasis have focused largely on overall survival. We investigated the impact of codon-specific KRAS mutations on the rates and patterns of recurrence in patients after surgery for colorectal liver metastasis (CRLM). All patients who underwent curative-intent surgery for CRLM between 2002 and 2015 at Johns Hopkins who had available data on KRAS mutation status were identified. Clinico-pathologic data, recurrence patterns, and recurrence-free survival (RFS) were assessed using univariable and multivariable analyses. A total of 512 patients underwent resection only (83.2%) or resection plus radiofrequency ablation (16.8%). Although 5-year overall survival was 64.6%, 284 (55.5%) patients recurred with a median RFS time of 18.1 months. The liver was the initial recurrence site for 181 patients, whereas extrahepatic recurrence was observed in 162 patients. Among patients with an extrahepatic recurrence, 102 (63%) had a lung recurrence. Although overall KRAS mutation was not associated with overall RFS (P = 0.186), it was independently associated with a worse extrahepatic (P = 0.004) and lung RFS (P = 0.007). Among patients with known KRAS codon-specific mutations, patients with codon 13 KRAS mutation had a worse 5-year extrahepatic RFS (P = 0.01), whereas codon 12 mutations were not associated with extrahepatic (P = 0.11) or lung-specific recurrence rate (P = 0.24). On multivariable analysis, only codon 13 mutation independently predicted worse overall extrahepatic RFS (P = 0.004) and lung-specific RFS (P = 0.023). Among patients undergoing resection of CRLM, overall KRAS mutation was not associated with RFS. KRAS codon 13 mutations, but not codon 12 mutations, were associated with a higher risk for overall extrahepatic recurrence and lung-specific recurrence. Cancer 2016. © 2016 American Cancer Society.

Hernia repair in the Lombardy region in 2000: preliminary results.

PubMed

Ferrante, F; Rusconi, A; Galimberti, A; Grassi, M

2004-08-01

Hernia repair is the most common surgical procedure in general surgery in Italy and in the Lombardy region. In the last decade, the use of mesh, the concept of a tension-free technique, and the postoperative rate of recurrences after Bassini or Shouldice operations have completely changed the surgical approach to hernia repair. For this reason, we sent a questionnaire to 148 surgical departments in the Lombardy region to investigate about total hernia operations performed in 2000 in Lombardy, the surgical approach, the surgical techniques used, the type of anesthesia and the hospital stay. One hundred five out of 148 surgical departments returned the questionnaire, and we collected information on a total of 16,935 surgical operations for hernia: 16,494 were performed using tension-free techniques. The inguinal anterior approach is the one of choice for primary and recurrent inguinal hernia, whereas the open preperitoneal and laparoscopic approaches are limited to bilateral and recurrent hernias. The majority of cases were treated under locoregional anesthesia and with a hospital stay of two nights.

Perioperative Interstitial High-Dose-Rate Brachytherapy for the Treatment of Recurrent Keloids: Feasibility and Early Results

DOE Office of Scientific and Technical Information (OSTI.GOV)

Jiang, Ping, E-mail: ping.jiang@uksh.de; Baumann, René; Dunst, Juergen

Purpose: To prospectively evaluate high-dose-rate brachytherapy in the treatment of therapy-resistant keloids and report first results, with emphasis on feasibility and early treatment outcome. Methods and Materials: From 2009 to 2014, 24 patients with 32 recurrent keloids were treated with immediate perioperative high-dose-rate brachytherapy; 3 patients had been previously treated with adjuvant external beam radiation therapy and presented with recurrences in the pretreated areas. Two or more different treatment modalities had been tried in all patients and had failed to achieve remission. After (re-)excision of the keloids, a single brachytherapy tube was placed subcutaneously before closing the wound. The target volumemore » covered the scar in total length. Brachytherapy was given in 3 fractions with a single dose of 6 Gy in 5 mm tissue depth. The first fraction was given within 6 hours after surgery, the other 2 fractions on the first postoperative day. Thus, a total dose of 18 Gy in 3 fractions was administered within 36 hours after the resection. Results: The treatment was feasible in all patients. No procedure-related complications (eg, secondary infections) occurred. Nineteen patients had keloid-related symptoms before treatment like pain and pruritus; disappearance of symptoms was noticed in all patients after treatment. After a median follow-up of 29.4 months (range, 7.9-72.4 months), 2 keloid recurrences and 2 mildly hypertrophied scars were observed. The local control rate was 94%. Pigmentary abnormalities were detected in 3 patients, and an additional 6 patients had a mild delay in the wound-healing process. Conclusions: The early results of this study prove the feasibility and the efficacy of brachytherapy for the prevention of keloids. The results also suggest that brachytherapy may be advantageous in the management of high-risk keloids or as salvage treatment for failure after external beam therapy.« less

Can a Silver-Coated Arthrodesis Implant Provide a Viable Alternative to Above Knee Amputation in the Unsalvageable, Infected Total Knee Arthroplasty?

In the unsalvageable, infected total knee arthroplasty, knee arthrodesis is one treatment option with lower reported reinfection rates compared with repeated 2-stage revision and improved function compared with amputation. One possible method for reducing incidence of recurrent infection treated by arthrodesis is the use of a silver-coated implant. We report our experience of silver-coated arthrodesis nails used for managing infected revision arthroplasty. We primarily assess the rate of reinfection and rate of amputation and report functional outcome measures. Retrospective analysis of all patients undergoing knee arthrodesis with a silver-coated arthrodesis nail between 2008 and 2014. Patient-reported data were recorded prearthrodesis and postarthrodesis (Oxford Knee Score and Short Form-36) as well as evidence of recurrent of infection, subsequent surgery, and the necessity for amputation. Eight patients underwent arthrodesis using the silver-coated arthrodesis nail. Mean duration of follow-up was 16 months (5-35 months). At the point of follow-up, there were no amputations, deaths, or implant revisions. One case of recurrent infection was successfully treated with washout and debridement. The mean prearthrodesis and postarthrodesis Oxford Knee Score difference was +8.9 points (P = .086) with significantly improved pain (P = .019), night pain (P = .021), and ease of standing (P = .003). Arthrodesis of the knee using a silver-coated intramedullary device is successful in eradicating infection and allowing limb conservation. Where infection does recur, this can be successfully treated with implant retention. The use of a silver-coated arthrodesis nail should be considered as an alternative to amputation for patients with a multiply revised and infected total knee arthroplasty.

Specific information about the nature of recurrent events that occur after each subtype of index stroke may be useful for refining preventive therapies. We aimed to determine whether stroke recurrence rates, the pattern of subtype recurrence, and prescription of secondary prevention agents differed according to initial stroke subtype. Multiple overlapping sources were used to recruit all first-ever stroke patients from a geographically defined region of Melbourne, Australia over a 3-year period from 1996 to 1999. Potential stroke recurrences (fatal and nonfatal) occurring within 2 years of the initial event were identified following patient interview and follow up of death records. Subjects were classified into the different Oxfordshire groups and the type of first-ever stroke was compared with recurrent stroke events. One thousand, three hundred and sixteen first-ever strokes were registered during the 3-year period (mean age 74.4 years). A total of 103 first recurrent stroke events (fatal and nonfatal) occurred among those with a first-ever ischemic stroke or intracerebral hemorrhage (ICH) during the 2-year follow-up period. The recurrent stroke subtype was different to the index stroke subtype in most (78%) patients. People with partial anterior circulation infarct had the greatest proportion of recurrences (13%), with a third of these being the more severe total anterior circulation infarct subgroup. The relative risk of ICH after an index lacunar infarct (LACI) compared with an index non-LACI was 4.06 (95% CI 1.10-14.97, P=0.038). Prescription of secondary prevention agents was greater at 2 years after stroke than at hospital discharge, and was similar between ischemic stroke subtypes. Approximately 9% of people with first-ever stroke suffered a recurrent event, despite many being prescribed secondary prevention agents. This has implications for the uptake of current preventive strategies and the development of new strategies. The possibility that ICH is greater among index LACI cases needs to be confirmed.

Intracerebral hemorrhage (ICH) is the most severe form of stroke. Survivors are at high risk of recurrence, death, and worsening functional disability. To investigate the association between blood pressure (BP) after index ICH and risk of recurrent ICH. Single-site, tertiary care referral center observational study of 1145 of 2197 consecutive patients with ICH presenting from July 1994 to December 2013. A total of 1145 patients with ICH survived at least 90 days and were followed up through December 2013 (median follow-up of 36.8 months [minimum, 9.8 months]). Blood pressure measurements at 3, 6, 9, and 12 months, and every 6 months thereafter, obtained from medical personnel (inpatient hospital or outpatient clinic medical or nursing staff) or via patient self-report. Exposure was characterized in 3 ways: (1) recorded systolic and diastolic measurements; (2) classification as adequate or inadequate BP control based on American Heart Association/American Stroke Association recommendations; and (3) stage of hypertension based on Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure 7 criteria. Recurrent ICH and its location within the brain (lobar vs nonlobar). There were 102 recurrent ICH events among 505 survivors of lobar ICH and 44 recurrent ICH events among 640 survivors of nonlobar ICH. During follow-up adequate BP control was achieved on at least 1 measurement by 625 patients (54.6% of total [range, 49.2%-58.7%]) and consistently (ie, at all available time points) by 495 patients (43.2% of total [range, 34.5%-51.0%]). The event rate for lobar ICH was 84 per 1000 person-years among patients with inadequate BP control compared with 49 per 1000 person-years among patients with adequate BP control. For nonlobar ICH the event rate was 52 per 1000 person-years with inadequate BP control compared with 27 per 1000 person-years for patients with adequate BP control. In analyses modeling BP control as a time-varying variable, inadequate BP control was associated with higher risk of recurrence of both lobar ICH (hazard ratio [HR], 3.53 [95% CI, 1.65-7.54]) and nonlobar ICH (HR, 4.23 [95% CI, 1.02-17.52]). Systolic BP during follow-up was associated with increased risk of both lobar ICH recurrence (HR, 1.33 per 10-mm Hg increase [95% CI, 1.02-1.76]) and nonlobar ICH recurrence (HR, 1.54 [95% CI, 1.03-2.30]). Diastolic BP was associated with increased risk of nonlobar ICH recurrence (HR, 1.21 per 10-mm Hg increase [95% CI, 1.01-1.47]) but not with lobar ICH recurrence (HR, 1.36 [95% CI, 0.90-2.10]). In this observational single-center cohort study of ICH survivors, reported BP measurements suggesting inadequate BP control during follow-up were associated with higher risk of both lobar and nonlobar ICH recurrence. These data suggest that randomized clinical trials are needed to address the benefits and risks of stricter BP control in ICH survivors.

A new esophageal stent with two anti-migration features was developed to minimize migration. The aim of this study was to evaluate the clinical efficacy and safety of this stent in patients with malignant dysphagia. A total of 40 patients with dysphagia due to a malignant obstruction of the esophagus were prospectively enrolled in this cohort study. Stent placement was technically successful in 39 patients (98 %). The median dysphagia-free time after stent placement was 220 days (95 % confidence interval 94 - 345 days). Nine patients (23 %) experienced recurrent dysphagia due to tissue overgrowth (n = 2), stent fracture (n = 1), and partial (n = 5) or complete (n = 1) stent migration. A total of 16 serious adverse events occurred in 14 patients (36 %), with hemorrhage (n = 3) and severe nausea or vomiting (n = 3) being the most common causes. This new stent design was effective for the palliation of malignant dysphagia and had a low rate of recurrent dysphagia. However, despite the anti-migration features, stent migration was still a major cause of recurrent dysphagia. Furthermore, treatment was associated with a high adverse event rate.

Numerous techniques exist for inguinal hernia treatment. Currently, open mesh tension-free repair is regarded as the repair method of choice. In particular Lichtenstein repair is the most common procedure performed, although several articles have reported long-lasting postoperative pain and a higher recurrence rate than originally reported. This study describes the P.A.D. (Protesi Autoregolantesi Dinamica) prosthesis implantation technique and reports postoperative complications and long-term results. From June 2002 to May 2005 a total of 214 patients underwent P.A.D. prosthesis inguinal repair. All patients were male, with a mean age of 51 years. All hernias were treated via an open inguinal approach using the original technique described by Valenti, with slight modifications. A total of 171'patients (80%) were available to follow-up 3 years after surgery. Early postoperative complications occurred in 14 patients (8.4%). Four patients (12.1%), who had undergone regional anaesthesia, developed urinary retention. Wound infection occurred in 3 patients (1.4%). There were two direct recurrences (0.93%) whereas chronic postoperative inguinal pain was reported in 4.2% of patients. Within the limitations of a short follow-up, our results show that the P.A.D. prosthesis procedure is a reliable technique with a low recurrence rate and low postoperative morbidity.

The aim of this paper was to investigate the risk of recurrence of lumbar disc herniation (LDH) in patients with scoliosis who underwent microdiscectomy. A series of consecutive patients who underwent microdiscectomy for LDH was retrospectively reviewed. The inclusion criteria were young adults younger than 40 years who received microdiscectomy for symptomatic 1-level LDH. An exclusion criterion was any previous spinal surgery, including fusion or correction of scoliosis. The patients were divided into 2 groups: those with scoliosis and those without scoliosis. The demographic data in the 2 groups were similar. All medical records and clinical and radiological evaluations were reviewed. A total of 58 patients who underwent 1-level microdiscectomy for LDH were analyzed. During the mean follow-up of 24.6 months, 6 patients (10.3%) experienced a recurrence of LDH with variable symptoms. The recurrence rate was significantly higher among the scoliosis group than the nonscoliosis group (33.3% vs. 2.3%, p = 0.001). Furthermore, the recurrence-free interval in the scoliosis group was short. Young adults (< 40 years) with uncorrected scoliosis are at higher risk of recurrent LDH after microdiscectomy.

The gold standard for the management of laryngeal squamous cell carcinoma in a previously irradiated patient is "salvage" total laryngectomy, but surgical management by partial laryngectomy can sometimes be proposed in selected patients. This study was designed to review the functional and oncological outcomes of patients treated by open partial laryngectomy for recurrent squamous cell carcinoma after failure of radiotherapy or involving previously irradiated tissues and to define prognostic criteria for the selection of patients eligible for this treatment strategy. In this retrospective study, 20 patients underwent partial laryngectomy between 2000 and 2011 for recurrence or second primary stage I or II laryngeal squamous cell carcinoma in an irradiated territory (11 vertical partial laryngectomies; 9 horizontal partial laryngectomies). The 3-year overall survival rate in patients with negative resection margins was 66%, with higher survival rates for tumours confined to the glottis, and the 2-year local control rate was 67%. Positive resection margins requiring total laryngectomy were observed in 20% of cases. The 3-year overall survival rate was 56% in these patients. Exclusive oral feeding was restored in 75% of patients after an average of 32 days. The tracheotomy tube was removed after an average of 18 days in 90% of patients. The disease-free functional larynx preservation rate was 45%. Salvage partial laryngectomy in irradiated tissues is an alternative treatment option to total laryngectomy in selected patients.

Purpose: To analyze the results of exclusive interstitial low-dose-rate brachytherapy (BT) for squamous cell carcinoma (SCC) of the penis, strictly confined to the glans. Methods and Materials: A total of 144 patients with SSC of the glans penis were treated with BT. Inguinal nodal dissection was performed in 19% of patients (all N-). After circumcision, BT was performed using the hypodermic needle technique. Median iridium length per patients was 24 cm (range, 4-108) and median dose was 65 Gy (range, 37-75). Median treated volume was 22 cm{sup 3} (range, 5-110) and median reference isodose rate was 0.4 Gy/h (range, 0.2-1.2).more » Results: Median follow-up was 5.7 years (range, 0.5-29). The 10-year penile recurrence, inguinal lymph node recurrence, and inguinal nodal metastasis rates were: 20% (CI 95%, 11-29), 11% (CI 95%, 5-17), and 6% (CI 95%, 2-10), respectively. After salvage treatment, 86% patients with local failure were in a complete remission at last follow-up. The 10-year probability of avoiding penile surgery (for complication or local recurrence) was 72% (CI 95%, 62-82). The 10-year cancer-specific survival rate was 92% (CI 95%, 87-97). Diameter of tumor significantly increased the risk of recurrence (p = 0.02). The 10-year painful ulceration and stenosis risk rates were: 26% (CI 95%, 17-35) and 29% (CI 95%, 18-40), respectively. Seven patients required excision for necrosis. Treated volume and reference isodose rate significantly increased the risk of complications. Conclusion: BT is an effective conservative treatment for SCC confined to the glans. Salvage local treatment is effective. Dose rate should be limited to decrease toxicity.« less

We report on the risk of miscarriage with high- and low-dosage periconceptional folic acid (FA) supplementation from a double-blind randomized clinical trial for prevention of orofacial cleft recurrence in Brazil. Women at risk of recurrence of orofacial clefts in their offspring were randomized into high (4 mg/day) and low (0.4 mg/day) doses of FA supplementation. The women received the study pills before pregnancy, and supplementation continued throughout the first trimester. Miscarriage rates were compared between the two FA groups and with the population rate. A total of 268 pregnancies completed the study protocol, with 141 in the 4.0-mg group and 127 in the 0.4-mg group. The miscarriage rate was 14.2% in the low-dose FA group (0.4 mg/day) and 11.3% for the high-dose group (4 mg/day) (P=0.4877). These miscarriage rates are not significantly different from the miscarriage rate in the Brazilian population, estimated to be around 14% (P=0.311). These results indicate that high-dose FA does not increase miscarriage risk in this population and add further information to the literature on the safety of high FA supplementation for prevention of birth defect recurrence.

To evaluate the rate of recurrence after pterygium excision with conjunctival autograft (CAG) using Tisseel fibrin tissue adhesive versus absorbable sutures. Forty-seven eyes of 42 patients who had undergone primary pterygium excision surgery with CAG were retrospectively reviewed. The study group, CAG adhered using Tisseel tissue adhesive (n = 27), were compared with the control group, CAG adhered using absorbable sutures (n = 20). Postoperative courses were followed for 22-36 months after surgery. Rates of recurrence were compared using logistic regression. Recurrence was defined as regrowth of fibrovascular tissue 1 mm past the corneoscleral limbus. The recurrence rate in the Tisseel group was 3.7% compared with 20% in the sutured group (P = 0.035). Recurrence rate in the Tisseel group was comparable to previously reported rates for CAG with sutures in the literature. There was a significant inverse relationship between age and rate of recurrence overall (P = 0.025). There was no difference in time to recurrence between the groups -- with an average time to recurrence of 3.13 months. In a predominantly Southern California population where there is an overall higher rate of pterygium recurrence, Tisseel tissue adhesive may improve surgical outcomes with equal to or lower long-term recurrence rates than previously reported.

Objectives: Laser cordectomy is very popular nowadays and become one of the treatments of choice for early glottis carcinoma. Transoral laser microsurgery has many advantages comparing conventional open surgery or radiation therapy. In this study, we examined the oncologic results of laser cordectomy for early glottic cancer and analyzed the prognostic impact on the survival of the several tumor-related and treatment-related factors. Methods: Patients who were diagnosed as early glottic squamous cell carcinoma, treated by laser cordectomy with curative intent were analyzed. Patients with preivous radiation therapy were included. From June 1988 to March 2005, 202 patients from five hospitals were analyzed (174 T1, 28 T2). Results: Five-year overall survival and disease-free survival were 98.4% and 84.9%. Twenty two patients developed local recurrence. Total laryngectomy was done in 6 patients and laryngeal preservation rate was 97%. Recurrence was higher in the patients with anterior commissure involvement (9/39) than without anterior commissure involvement (13/163). Recurrence was higher in T1b (4/15) than T1a (13/159). Previous radiation was also highly related to the recurrence (7/20 vs 15/182). Twenty patients with local recurrence after radiation therapy were treated by salvage laser cordectomy. Of them, 7 patients developed local recurrence and 5 year disease-free survival was 57%. Complication was rare with one case of hemorrhage. Tracheotomy was not necessary in all patients. Conclusions: Laser cordectomy for early glottic carcinoma showed high survival, laryngeal preservation rate and low complication rate. The prognostic factors were anterior commissure involvement, both vocal fold involvement and previous radiotherapy.

Chloroquine has been recommended for Plasmodium vivax infections for >60 years, but resistance is increasing. To guide future therapies, the cumulative benefits of using slowly eliminated (chloroquine) vs rapidly eliminated (artesunate) antimalarials, and the risks and benefits of adding radical cure (primaquine) were assessed in a 3-way randomized comparison conducted on the Thailand-Myanmar border. Patients with uncomplicated P. vivax malaria were given artesunate (2 mg/kg/day for 5 days), chloroquine (25 mg base/kg over 3 days), or chloroquine-primaquine (0.5 mg/kg/day for 14 days) and were followed for 1 year. Recurrence rates and their effects on anemia were compared. Between May 2010 and October 2012, 644 patients were enrolled. Artesunate cleared parasitemia significantly faster than chloroquine. Day 28 recurrence rates were 50% with artesunate (112/224), 8% with chloroquine (18/222; P < .001), and 0.5% with chloroquine-primaquine (1/198; P < .001). Median times to first recurrence were 28 days (interquartile range [IQR], 21-42) with artesunate, 49 days (IQR, 35-74) with chloroquine, and 195 days (IQR, 82-281) with chloroquine-primaquine. Recurrence by day 28, was associated with a mean absolute reduction in hematocrit of 1% (95% confidence interval [CI], .3%-2.0%; P = .009). Primaquine radical cure reduced the total recurrences by 92.4%. One-year recurrence rates were 4.51 (95% CI, 4.19-4.85) per person-year with artesunate, 3.45 (95% CI, 3.18-3.75) with chloroquine (P = .002), and 0.26 (95% CI, .19-.36) with chloroquine-primaquine (P < .001). Vivax malaria relapses are predominantly delayed by chloroquine but prevented by primaquine. NCT01074905.

This retrospective study was performed to investigate the need for management modification in MBC according to evaluation of characteristics and failure patterns compared with IDC. We performed this multicenter study taking MBC and randomly assigned IDC cases matched for age (± 3 years), pathologic stage (T and N), locoregional treatment methods (surgery with or without radiation therapy), and period of treatment (± 6 months) that occurred from January 1999 to November 2011 in the 6 institutions of the Korean Radiation Oncology Group. A total of 144 female MBC patients were enrolled. The median follow-up was 51 months (range, 1-186 months). The rates of positivity for estrogen receptor (P < .001), progesterone receptor (P < .001), and HER2 (P = .007) were significantly lower in MBC patients. During follow-up, recurrence developed in 22 (15.3%) MBC and 6 (4.2%) IDC patients (P = .002). The median time to recurrence of MBC and IDC was 15 months and 24 months, respectively. Most instances of recurrence in MBC developed in the triple-negative (TN) subgroup (TN-MBC). In particular, locoregional recurrence developed exclusively in the TN-MBC subgroup. In the TN-MBC subgroup, the number of risk factors (pT2-3, N1-3) was related to significant differences in overall survival (P = .001) and recurrence-free survival (P < .001). The MBC patients had a higher rate of TN, poorer differentiation, and a higher recurrence rate than did the IDC patients. Considering the unique characteristics and failure patterns, it is necessary to modify the current management guidelines for MBC. Copyright © 2015 Elsevier Inc. All rights reserved.

There is conflicting evidence regarding the oncological impact of anastomotic leak following colorectal cancer surgery. This study aims to test the hypothesis that anastomotic leak is independently associated with local recurrence and overall and cancer-specific survival. Analysis of prospectively collected data from multiple centres in Victoria between 1988 and 2015 including all patients who underwent colon or rectal resection for cancer with anastomosis was presented. Overall and cancer-specific survival rates and rates of local recurrence were compared using Cox regression analysis. A total of 4892 patients were included, of which 2856 had completed 5-year follow-up. The overall anastomotic leak rate was 4.0%. Cox regression analysis accounting for differences in age, sex, body mass index, American Society of Anesthesiologists score and tumour stage demonstrated that anastomotic leak was associated with significantly worse 5-year overall survival (χ 2 = 6.459, P = 0.011) for colon cancer, but only if early deaths were included. There was no difference in 5-year colon cancer-specific survival (χ 2 = 0.582, P = 0.446) or local recurrence (χ 2 = 0.735, P = 0.391). For rectal cancer, there was no difference in 5-year overall survival (χ 2 = 0.266, P = 0.606), cancer-specific survival (χ 2 = 0.008, P = 0.928) or local recurrence (χ 2 = 2.192, P = 0.139). Anastomotic leak may reduce 5-year overall survival in colon cancer patients but does not appear to influence the 5-year overall survival in rectal cancer patients. There was no effect on local recurrence or cancer-specific survival. © 2016 Royal Australasian College of Surgeons.

Lumbar drains (LD) are commonly used during endoscopic repair of cerebrospinal fluid (CSF) rhinorrhea, either to facilitate graft healing or to monitor CSF fluid dynamics. However, the indications and necessity of LD placement remains controversial. The current study sought to evaluate endoscopic CSF leak repair outcomes in the setting of limited LD use. Patients who underwent endoscopic repair of CSF rhinorrhea between 2004 and 2014 were identified by a review of medical records. Demographic and clinical data were extracted and compared between patients who had surgery with and patients who had surgery without a perioperative LD. A univariate analysis was performed to identify factors predictive of recurrence. A total of 107 patients (116 surgical procedures) were identified, with a mean follow-up of 15.8 months. Eighty-eight of 107 patients (82.2%) had surgery without an LD. The mean hospital stay was 4.48 days in the LD group versus 1.03 days in the non-LD group (p < 0.00001). There was no difference in recurrence rate between the LD and non-LD groups. Predictors of recurrence included repair technique (p = 0.04) and size of defect (p = 0.005). Body mass index, leak site (ethmoid, sphenoid, frontal), and etiology (spontaneous, iatrogenic, traumatic) were not predictive of leak recurrence. Use of LDs in endoscopic CSF leak repair was not associated with reduced recurrence rates, regardless of leak etiology, and resulted in a significant increase in hospital length of stay. Although the use of perioperative LDs to monitor CSF dynamics may have some therapeutic and diagnostic advantages, it may not be associated with clinically significant improvements in patient outcomes or recurrence rates.

Objectives: The optimal adjuvant therapy for International Federation of Gynecology and Obstetrics (FIGO) stage I papillary serous (UPSC) or clear cell (CC) endometrial cancer is unknown. We report on the largest single-institution experience using adjuvant high-dose-rate vaginal brachytherapy (VBT) for surgically staged women with FIGO stage I UPSC or CC endometrial cancer. Methods and Materials: From 1998-2011, 103 women with FIGO 2009 stage I UPSC (n=74), CC (n=21), or mixed UPSC/CC (n=8) endometrial cancer underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy followed by adjuvant high-dose-rate VBT. Nearly all patients (n=98, 95%) also underwent extended lymph node dissection of pelvic andmore » paraortic lymph nodes. All VBT was performed with a vaginal cylinder, treating to a dose of 2100 cGy in 3 fractions. Thirty-five patients (34%) also received adjuvant chemotherapy. Results: At a median follow-up time of 36 months (range, 1-146 months), 2 patients had experienced vaginal recurrence, and the 5-year Kaplan Meier estimate of vaginal recurrence was 3%. The rates of isolated pelvic recurrence, locoregional recurrence (vaginal + pelvic), and extrapelvic recurrence (including intraabdominal) were similarly low, with 5-year Kaplan-Meier estimates of 4%, 7%, and 10%, respectively. The estimated 5-year overall survival was 84%. On univariate analysis, delivery of chemotherapy did not affect recurrence or survival. Conclusions: VBT is effective at preventing vaginal relapse in women with surgical stage I UPSC or CC endometrial cancer. In this cohort of patients who underwent comprehensive surgical staging, the risk of isolated pelvic or extrapelvic relapse was low, implying that more extensive adjuvant radiation therapy is likely unnecessary.« less

Despite the availability of highly effective treatments, there is a significant recurrence rate of benign paroxysmal positional vertigo (BPPV). This study is aimed to quantitatively measure sleep quality in BPPV patients and correlate it with the recurrence of BPPV. In this longitudinal cohort study, the clinical records of 67 elderly or middle-aged adult patients who were diagnosed with BPPV at Neurology Clinic, Beijing Chaoyang Hospital affiliated to Capital Medical University between 2013 and 2014. The "Recurrent" and "Non-recurrent" BPPV were respectively defined. Primary data collection included the medical history, blood test and Pittsburgh sleep quality index measurement. Among the total 67 patients after successful treatment, recurrent BPPV is observed in 37.31% patients (n = 25) within 2 years. Among all 11 variables analyzed between recurrent and non-recurrent groups, only the Pittsburgh Sleep Quality Index (PSQI) scores showed significant difference (P < 0.001). In details, these differences were also measured in five individual sleep items, including the subjective assessment of sleep quality, sleep latency, sleep duration, the use of sleep-aid medication and daytime dysfunctions (all P < 0.05). Regression analysis showed patients with higher PSQI score (lower sleep quality) had higher risk of BPPV recurrence (OR = 1.17, 95% CI: 1.04-1.32, P= 0.0082). The sleep quality in patients with BPPV recurrence is significantly poorer compared to non-recurrent patients. Our result suggested sleep quality as measured by PSQI is an independent risk factor of BPPV recurrence.

The standard management of upper urinary tract urothelial carcinoma (UUT-UC) is nephroureterectomy with bladder cuff excision, but after surgery, approximately 22-47% of patients with UUT-UC develop subsequent bladder tumour recurrence, potentially because of the implantation of cancer cells from the primary tumour. To conduct a meta-analysis to evaluate the effect of prophylactic intravesical chemotherapy in the prevention of bladder recurrence after nephroureterectomy for UUT-UC. An electronic database search of Medline, Embase, the Cochrane Library, CancerLit and ClinicalTrials.gov was performed to identify appropriate studies prior to March 2013.All studies comparing nephroureterectomy alone with prophylactic intravesical chemotherapy after nephroureterectomy were included. The main outcome measure for this meta-analysis was the rate of bladder recurrence after nephroureterectomy. The search was not limited by language. The review process followed the guidelines of the Cochrane Collaboration. The analysis was conducted using the Review Manager Version RevMan 5.0 software (The Nordic Cochrane Centre, The Cochrane Collaboration). A total of 592 patients were included in this study, of whom 257 underwent intravesical instillation after nephroureterectomy and 335 underwent nephroureterectomy alone. Our meta-analysis demonstrated that the rate of recurrence after 12 months was significantly lower in the intravesical instillation after nephroureterectomy group than in the nephroureterectomy-alone group [odds ratio (OR): 0.48; 95% confidence interval (CI): 0.28-0.81; P = 0.006]. A significant decrease in bladder recurrence after at least 24  months was also observed in the intravesical instillation after nephroureterectomy group (OR: 0.40; 95% CI: 0.24-0.67; P = 0.0004). A subgroup analysis demonstrated that the pattern of differences was similar to those from the total group analysis. Prophylactic intravesical chemotherapy was effective for the prevention of bladder recurrence after nephroureterectomy. Therefore, we suggest that prophylactic intravesical chemotherapy should be performed in patients with UUT-UC after nephroureterectomy, but the optimal chemotherapy regimen and the initial time of instillation should be explored in future studies.

Gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (MRI) performed before curative therapy for hepatocellular carcinoma (HCC) can distinguish between intrahepatic distant recurrence and hypervascularization. This study aimed to retrospectively evaluate the presence of non-hypervascular hypointense nodules on hepatobiliary phase images from Gd-EOB-DTPA-enhanced MRI as a risk factor of the intrahepatic distant recurrence of early stage HCC following radiofrequency ablation (RFA). A total of 132 patients who underwent preprocedural Gd-EOB-DTPA-enhanced MRI followed by initial RFA were retrospectively analyzed. Post-RFA intrahepatic distant recurrence, which excluded the hypervascularization of non-hypervascular hypointense nodules detected by preprocedural Gd-EOB-DTPA-enhanced MRI, was evaluated according to the presence of non-hypervascular hypointense nodules on preprocedural Gd-EOB-DTPA-enhanced MRI. Intrahepatic distant recurrence rates following RFA were higher in patients with non-hypervascular hypointense nodules (1-year: 22.5%, 2-year: 52.1%, 5-year: 89.1%) compared with in patients without non-hypervascular hypointense nodules (1-year: 7.0%, 2-year: 28.8%, 5-year: 48.7%). The presence of non-hypervascular hypointense nodules was associated with markedly increased cumulative recurrence rates of both identical and different subsegment intrahepatic distant recurrence, being an independent risk factor for post-RFA identical and different subsegment intrahepatic distant recurrence (identical: HR = 2.365, P = 0.027; different: HR = 3.276, P < 0.001). The presence of non-hypervascular hypointense nodules on hepatobiliary phase images from Gd-EOB-DTPA-enhanced MRI obtained prior to RFA is an important predictive factor of intrahepatic distant recurrence following RFA of HCC. © 2016 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

SUMMARY Our objective was to evaluate recurrence patterns of hypopharyngeal and laryngeal carcinoma after chemoradiation and options for salvage surgery, with special emphasis on elderly patients. In a retrospective study all patients who underwent chemoradiation for hypopharyngeal and laryngeal carcinoma in a tertiary care academic center from 1990 through 2010 were evaluated. Primary outcome measures were the survival and complication rates of patients undergoing salvage surgery, especially in elderly patients. Secondary outcome measures were the predictors for salvage surgery for patients with locoregional recurrence after failed chemoradiotherapy. A review of the literature was performed. Of the 136 included patients, 60 patients had recurrent locoregional disease, of whom 22 underwent salvage surgery. Fifteen patients underwent a total laryngectomy with neck dissection(s) and 7 neck dissection without primary tumour surgery. Independent predictors for salvage surgery within the group of 60 patients with recurrent disease, were age under the median of 59 years (p = 0.036) and larynx vs. hypopharynx (p = 0.002) in multivariate analyses. The complication rate was 68% (14% major and 54% minor), with fistulas in 23% of the patients. Significantly more wound related complications occurred in patients with current excessive alcohol use (p = 0.04). Five-year disease free control rate of 35%, overall survival rate of 27% and disease specific survival rate of 35% were found. For the 38 patients who were not suitable for salvage surgery, median survival was 12 months. Patients in whom the tumour was controlled had a 5-year overall survival of 70%. In patients selected for salvage surgery age was not predictive for complications and survival. In conclusion, at two years follow-up after chemoradiation 40% of the patients were diagnosed with recurrent locoregional disease. One third underwent salvage surgery with 35% 5-year disease specific survival and 14% major complications. Older patients selected for salvage surgery had a similar complication rate and survival as younger patients. PMID:26246660

This study evaluates the oncological outcome of patients with recurrent oropharyngeal squamous cell carcinoma (OPSCC) after primary radiation therapy +/- chemotherapy, primary surgical therapy, and surgical therapy followed by radiation therapy +/- chemotherapy. A total of 156 patients (36%) of a cohort of 427 treated for OPSCC between 1990 and 2006 developed recurrent disease. Fifty-one patients (12%) qualified for salvage treatment. Study endpoints were 5-year overall survival (OS) and disease-specific survival (DSS). The 5-year OS and DSS rates after salvage treatment were 29% and 40%; after initial primary radiation therapy, 25% and 40%; after initial surgery followed by radiation therapy, 40% and 40%; and after initial surgery alone, 20% and 40%. Patients with an advanced OPSCC have a considerable risk for recurrence. Despite poor ultimate outcome, salvage treatment should be attempted in patients with resectable disease, good performance status, and absence of distant metastases. 2009 Wiley Periodicals, Inc.

To investigate the clinical characteristics and treatment results of adult patients with ocular toxocariasis. A total of 54 consecutive patients who were clinically and serologically diagnosed with ocular toxocariasis were retrospectively reviewed. Among patients, 66.7 and 77.3% showed increases in eosinophil cationic protein (ECP) and total Ig E in serum, respectively. Four eyes (7.2%) initially presented as neuroretinitis with subsequent motile retinal lesion. The recurrence rates in the combination treatment group with albendazole and corticosteroids were significantly lower than those in the steroid-alone group during the mean follow-up of 27.6 months (p = 0.001). The adjunctive test of serum total IgE level may be helpful for the diagnosis of ocular toxocariasis. Ocular toxocariasis should be considered in the differential diagnosis of unilateral neuroretinitis with subsequent motile retinal lesion. Combined treatment with albendazole and corticosteroids appeared to be effective for reducing the recurrence of intraocular inflammation.

AIM: To demonstrate that administering heparanase inhibitor PI-88 at 160 mg/d is safe and promising in reducing hepatocellular carcinoma (HCC) recurrence for up to 3 year following curative resection. METHODS: A total of 143 patients (83.1% of the 172 participants in the phase II study) participated in the follow-up study. Of these patients, 50 had received no treatment, 48 had received 160 mg/d PI-88, and 45 had received 250 mg/d PI-88 during the phase II trial. Safety parameters and the following efficacy endpoints were investigated: (1) time to recurrence; (2) disease-free survival; and (3) overall survival. RESULTS: PI-88 at 160 mg/d delayed the onset and frequency of HCC recurrence, and provided a clinically significant survival advantage for up to 3 years after treatment compared with those of the control group: (1) the recurrence-free rate increased from 50% to 63%, and (2) time to recurrence at the 36th percentile was postponed by 78%. The efficacy of administering PI-88 at 250 mg/d was confounded by a high dropout rate (11 out of 54 patients). Additionally, subgroup analyses of patients with (1) multiple tumors or a single tumor ≥ 2 cm; and (2) hepatitis B or C revealed that administering PI-88 at 160 mg/d conferred the most significant survival advantage (56.8% improvement in disease-free survival, P = 0.045) for patients with both risk factors for recurrence. CONCLUSION: Administering PI-88 at 160 mg/d is a safe and well-tolerated dosage that may confer significant clinical benefits for patients with HCC. PMID:25170226

To evaluate the outcomes of re-exposure to low-osmolar iodinated contrast medium (LOCM) in patients with a history of moderate-to-severe hypersensitivity reaction (HSR). We retrospectively evaluated a cohort comprising all subjects satisfying the following conditions at 11 centres: (1) experienced a moderate-to-severe HSR to LOCM by December 2014, and (2) underwent contrast-enhanced computed tomography after the initial HSR between January 2014 and December 2014. A total of 150 patients with 328 instances of re-exposure were included; the recurrence rate of HSR was 19.5%. Patients with severe initial HSR exhibited a higher recurrence rate of severe HSR compared to patients with moderate initial HSR, despite more intensive premedication. In the multivariate analysis, the independent risk factors for recurrence of HSR were diabetes, chronic urticaria, drug allergy other than to iodinated contrast media (ICM) and severe initial HSR. The risk of recurrent HSR was 67.1% lower in cases where the implicated ICM was changed to another one (odds ratio: 0.329; P = 0.001). However, steroid premedication did not show protective effects against recurrent HSR. In high-risk patients who have previously experienced a moderate-to-severe initial HSR to LOCM, we should consider changing the implicated ICM to reduce recurrence risk. • In patients with moderate-to-severe HSR, steroid premedication only shows limited effectiveness. • Changing the implicated ICM can reduce the recurrence of HSR to ICM. • Diabetes, chronic urticaria and drug allergies increase the risk of ICM HSR.

To evaluate the anatomical, functional and post-operative outcomes of polypropylene mesh (Prolift™) in the surgical management of pelvic organ prolapse (POP). A single-centre observational study of 106 successive patients, who underwent Prolift™ mesh repair (POP ≥ 2) with a median follow-up of 4 years, was performed. Outcomes of interest measured included patient demographics, intra and post-operative complications, concomitant procedures for POP or urinary incontinence. Using the Baden-Walker classification, grade ≥2 prolapses in the operated compartment were deemed as surgical failure. Validated questionnaires including ICIQ-VS and ICIQ-UI were used to assess functional outcome. Of the 106 patients, 56 had an anterior, 36 a posterior and 14 a total Prolift™. 101 patients were available for follow-up (median 4 years). 82 women underwent a clinical follow-up whilst 19 underwent a telephonic follow-up. Peri-operative bladder injury was noted in 2 (1.9 %) cases. Six (5.6 %) patients developed mesh exposure post-operatively. Re-operation rates for recurrent prolapse in the operated compartment were 2.8 % (n = 3). At follow-up, prolapse recurrence in the operated compartment was noted in another 7.3 % (n = 6) patients. Combining re-operations for POP and recurrences noted during follow-up, the revised failure rate was 10.1 % (n = 9). De novo prolapse in the non-operated compartment occurred in 19.5 % (n = 16) women. Our study demonstrates that Prolift™ vaginal mesh surgery offers anatomical cure rates of 89.9 %. A higher rate of de novo recurrence in the non-operated compartment was noted suggesting that surgical correction in one compartment may exacerbate recurrence in other compartments.

To compare the differences in the clinical efficacy on depression differentiated as yang deficiency between the combined therapy of ginger-isolated moxibustion and escitalopram and the simple application escitalopram. Eighty patients of depression differentiated as yang deficiency were randomized into an observation group and a control group, 40 cases in each one. In the control group, escitalopram was prescribed for oral administration, 10 mg a day, after each breakfast. In the observation group, on the basis of the treatment as the control group, the ginger-isolated moxibustion was supplemented at Dazhui (GV 14) and bilateral back- shu points of five zang organs[Xinshu (BL 15), Ganshu (BL 18), Pishu (BL 20), Feishu (BL 13) and Shenshu (BL 23)]. Moxibustion was used 5 times a week. Twenty times of moxibustion were taken as one session and totally 3 sessions were required (totally 84 days). After 3 sessions of treatment, the concentration of serum 5-hydroxytryptamine (5-HT) before and after treatment and clinical efficacy were observed in the two groups. After 3 sessions of treatment, escitalopram was taken continuously, 10 mg a day for 9 months in the two groups and the recurrent rate was observed in a half year after discontinuity of medication in the two groups. The total effective rate was 97.5% (39/40) in the observation group and was 92.5% (37/40) in the control group. The total effective rate was similar between the two groups (both P >0.05). The curative and remarkably effective rate was 82.5% (33/40) in the observation group, better than 62.5% (25/40) in the control group ( P <0.05). The serum 5-HT after treatment was increased as compared with that before treatment in the patients of the two groups (both P <0.05), but the diffe-rence was not significant statistically between the two groups ( P >0.05). The recurrent rate of depression was 7.7% (3/39) in the observation group, lower than 27.0% (10/37) in the control group ( P <0.05). The combined therapy of ginger-isolated moxibustion and escitalopram achieves the better curative and remarkably effective rate as compared with the simple western medicine and it significantly reduces the recurrence of depression.

The best management for diverticulitis with abscess formation remains unknown. The purpose of this study was to determine the natural course and outcomes of patients with medically treated diverticular abscess. We conducted a retrospective review of all patients at our institution with diverticular abscess confirmed by CT from 2004 to 2014. This study was conducted in a tertiary referral hospital. A total of 1194 patients were treated for acute diverticulitis in 10 years; 210 patients with CT-documented diverticular abscess were analyzed (140 men (66.7%) and 70 women (33.3%); median age 45 years; range, 23-84 years). Overall recurrence and disease complication rates, as well as the need for subsequent operation after initial successful nonsurgical management, were measured, along with analysis of the whole cohort and the subgroup of patients with percutaneous drainage for diverticular abscess. During the initial presentation, 25 patients failed nonoperative management and required an urgent operation. A total of 185 patients were initially successfully managed without surgery and were discharged from the hospital. Of these, recurrent diverticulitis developed in 112 (60.5%) after an average time interval of 5.3 months (range, 0.8-20.0 months); 47 patients (42%) experienced more than 1 episode. The modified Hinchey stage at time of recurrence (compared with index stay) increased in 51 patients (45.6%). Seventy one (63%) of 112 recurrences showed local disease complications (recurrent abscess, fistula, stricture, or peritonitis). Fistula formation (colovesicular/colovaginal/colocutaneous) and recurrent abscess were the 2 most frequent complications. Twenty nine (26%) of 112 recurrences required an urgent operation; overall, 66 (59%) of 112 patients eventually underwent surgery at our institution. The original abscess size in patients who later developed recurrences was significantly larger than in patients who did not develop recurrence (5.3 vs 3.2 cm; p < 0.001). Paradoxically, larger abscesses also had a higher chance of successful CT-guided drainage (average size, 6.5 cm; range, 1.1-14 cm), yet CT-guided drainage did not change the overall outcome. Of 65 (31.0%) of 210 patients with CT-guided drainage, 45 (73.8%) of 61 after initial success experienced a recurrence. Furthermore, local disease complications at the time of recurrence were noted in 32 of 61 patients (52.5% of all CT-guided drainage, 71.1% of post-CT-guided drainage recurrences), and 13 (29.2%) of 45 patients with recurrence after successful CT-guided drainage subsequently required an urgent operation. The study was limited by its retrospective noncomparative design. Diverticular abscesses represent complicated diverticulitis and are associated with a high risk of recurrences and disease complications. Recurrences (contrary to other series) were often more severe than the index presentation. The successful CT-guided drainage of a diverticular abscess does not appear to lower the risks of future recurrence or complication rates and frequently is only a bridge to surgery. After initial successful nonoperative management, patients with diverticular abscess should be offered interval elective colectomy (see Video, Supplemental Digital Content 1, http://links.lww.com/DCR/A216).

Complex inguinal hernia repairs.

Complex inguinal hernia treatment is a challenge for general surgeons. The gold standard for the repair of inguinal hernias is the Lichtenstein repair (anterior approach). However, when multiple recurrent hernias or giant hernias are present, it is necessary to choose different approaches because the incidence of poor results increases. There are many preperitoneal approaches described in the literature. For example: (a) open procedure-Nyhus and Stoppa (b) laparoscopic technique-transabdominal pre-peritoneal (TAPP) and totally extraperitoneal (TEP). In this study, we show how we repair complicated cases using open access in huge unilateral or bilateral, recurrent, or multiple recurrent inguinal hernias. The present study includes the period from November 1993 through December 2007. One hundred and eighty-eight patients, divided into 121 with unilateral hernias and 67 with bilateral hernias, totaling 255 inguinal hernia repairs, were treated by the Nyhus or Stoppa preperitoneal approach, depending on whether they were unilateral or bilateral. We used progressive preoperative pneumoperitoneum for oversize inguinal hernias in all patients. Orchiectomy was necessary on only two occasions. Despite the repair complexity involved, we had only two known recurrences. The mortality was zero and the morbidity was acceptable. We conclude that an accurate open preperitoneal approach using mesh prosthesis for complex inguinal hernias is safe, with very low recurrent rates and low morbidity. Progressive preoperative pneumoperitoneum for giant hernias was shown to be an important factor in accomplishing good intraoperative and immediate postoperative results.

Abstract Background: Bacterial vaginosis is a condition of unknown etiology, associated with an imbalance of the normal vaginal microbiota, characterized by a high recurrence rate despite of classical therapy solutions. Probiotics are microorganisms, which taken in adequate amounts, are proven to bring health benefits in human and animal bodies, by re-establishing the normal flora at different levels. Objective: The present article studies the possibility of using probiotic treatment as an adjuvant therapy for nonspecific vaginosis and reducing its recurrence rate. Methods: We have evaluated the evolution of patients with bacterial vaginosis who received the classical antibiotic therapy and a probiotic product. The study group consisted of 173 non-pregnant, sexually active patients, 20-45 years old, with no additional health problems and no contraceptive undergoing treatment, which have been admitted to the department of Obstetrics and Gynecology of the Bucharest Emergency University Hospital between 1.01.2012-31.12.2012.The bacteriological evaluation was made on cervical and vaginal cultures. Results: From a total of 173 patients, those who used probiotics oral capsules while taking an antibiotic had lower recurrence rates. More than a half of women who did not use any probiotic product had 3 or more relapse episodes per year. Vaginal capsules with probiotics have also proven to be useful in lowering the recurrence rate, but research is still needed. Conclusion: Probiotic products are proven to be a helpful adjuvant therapy for bacterial vaginosis, with no adverse outcomes. PMID:24868256

We reviewed our series of anal squamous cell carcinomas (ASCC) treated over the last two decades. ASCC patients undergoing treatment at the Leicester Royal Infirmary between 1998 and 2016 were selected. Age, gender, pathological tumor characteristics, treatment adopted, the overall survival (OS), cancer-specific survival (CSS), and disease-free survival (DFS) at 5-year follow-up were recorded and calculated. A total of 190 ASCC were reviewed, of these 64.2% (n = 122) received primary radical chemoradiotherapy. Complete response rate was 92.6% (n = 113) and four patients with residual disease underwent a salvage APER. Twenty-eight patients experienced recurrent disease (23.0%) either systemic (n = 8), local (n = 14), or both (n = 6); six had a salvage APER. Complete follow-up data are available for 63.1% patients (77/122). Overall, the locoregional failure rate of primary chemoradiotherapy (residual + recurrent disease) was present in 29 patients (29/122; 23.8%). OS was 41.6% CSS was 69.2% and DFS 60.0% at 5 years follow-up. In our series of ASCC primary chemoradiotherapy had achieved significant initial complete response rates, however, long term-follow ups still present systemic and local recurrences. APR is able to treat 30% of the pelvic recurrences (6/20), the others are either associated with systemic disease or locally inoperable masses. © 2017 Wiley Periodicals, Inc.

The method of treatment cessation and recurrence rate of amblyopia.

2009-09-01

To date, much of the research regarding amblyopia has been focused on which therapeutic modality is the most efficacious in amblyopia management. Unfortunately, there is a lack of research into which method of treatment cessation is the most appropriate once therapy has been completed. The purpose of this study is to investigate if the cessation method affects the recurrence rate of amblyopia. This study was a prospective randomized clinical trial of 20 subjects who were wearing full-time occlusion and were at the end point of their therapy. The subjects were randomized into one of two groups: abrupt cessation or therapy tapering. All subjects were followed for 3 consecutive 4-week intervals, for a total of 12 weeks, to assess the short-term recurrence rate of amblyopia. Subjects who were in the tapered group had their occlusion reduced from full-time occlusion (all waking hours minus one) to 50% of waking hours at study enrollment (i.e., from 12 hours/day to 6 hours per day); occlusion was reduced by an additional 50% at the first 4-week study visit (i.e., from 6 hours/day to 3 hours), with occlusion being discontinued completely at the week 8 visit. All subjects who were in the abrupt cessation group had their full-time occlusion discontinued completely at the start of the study (i.e., from 12 hours/day to none). Additional assessments were also conducted at week 26 and week 52 post-therapy cessation to determine the longer term amblyopia regression rate. For the purposes of this study, recurrence was defined as a 0.2 (10 letters) or more logarithm of the minimum angle of resolution (logMAR) loss of visual acuity. A recurrence of amblyopia occurred in 4 of 17 (24%; CI 9%-47%) participants completing the study by the week 52 study end point. There were 2 subjects from each treatment group who demonstrated a study protocol-defined recurrence. There was a 24% risk of amblyopia recurrence if therapy was discontinued abruptly or tapered in 8 weeks. In this small sample, the assigned cessation method did not affect the rate of amblyopia recurrence. It is recognized that the smaller sample size in our study prevents us from making definitive conclusions on the potential role that abrupt cessation has on the regression rate of amblyopia. The sample size was too small to reach an acceptable level of statistical power; therefore the generalizability of the findings to the broad population of all patients with amblyopia requires continuing research. This study therefore could be considered as a pilot study.

The course of all 113 patients with Crohn's disease whose initial procedure involved an anastomosis operated upon from 1942 to 1972 was followed through 1980. The calculated cumulative 30-year total mortality was 23.4%, 16.7% disease-related. The cumulative recurrence rate was 29% at five years, 52% at ten years, 64% at 15 years and 84% at 25 years, with no important differences between disease locations and types of operation. Sex, age, duration, granulomas, enteral or perirectal fistulas and length of the resection, the disease, and the proximal resection margin had no significant influence on the rates of development of recurrent disease or on functional outcome. By far the most common site of recurrence was the neo-terminal ileum, but in ileocolitis compared with ileitis, recurrence was 5.2 times more likely (p = 0.0001) to involve the adjacent or remote colon as well. Moreover, only 1/63 ileitis patients eventually required ileostomy, whereas 15/47 patients with ileocolitis or colitis ultimately required this procedure (p less than 0.001). The current status of the patients was excellent or good in 64% and unwell or dead related in 24%. Urolithiasis developed in 19%. PMID:7114939

The squamous cell carcinomas represent about 90 % of all head and neck cancers, ranking the sixth most common human cancer. Approximately 450,000 of new cases of head and neck squamous cell carcinoma (HNSCC) are diagnosed every year. Unfortunately, because of diagnosis at the advanced stages and early metastasis to the lymph nodes, the HNSCC is associated with very high death rate. Identification of signature biomarkers and molecularly targeted therapies could provide more effective and specific cancer treatment, prevent recurrence, and increase survival rate. We used paired tumor and adjacent normal tissue samples to screen with RT² Profiler™ PCR Array Human Cancer PathwayFinderTM. Total of 20 up-regulated genes and two down-regulated genes were screened out. Out of 22 genes, 12 genes were subsequently validated to be significantly altered in the HNSCC; the samples were from all 41 patients. Five year survival and recurrence selected genes that could represent the biomarkers of survival and recurrence of the disease. We believe that comprehensive understanding of the unique genetic characteristics of HNSCC could provide novel diagnostic biomarkers and meet the requirement for molecular-targeted therapy for the HNSCC.

Surgical resection with negative margins is part of the curative treatment of gastric adenocarcinoma. Positive surgical margins are associated with worse outcome. The aim of the present study was to determine the clinical usefulness of extending the proximal surgical margin in patients undergoing total gastrectomy for gastric adenocarcinoma. A retrospective analysis of patients that underwent total gastrectomy within the time frame of 2002 and 2017 was conducted. Patients diagnosed with adenocarcinoma that underwent curative surgery were included. Patients were divided into three groups, depending on proximal surgical margin status: negative margin (R0), positive margin with additional resection to achieve negative margin (R1-R0), and positive margin (R1). Demographic and clinical variables were analyzed. The outcome measures to evaluate were recurrence, disease-free survival, and overall survival. Forty-eight patients were included in the study. Thirty-seven were classified as R0, 9 as R1-R0, and 2 as R1. Fifty-two percent of the patients had clinical stage III disease. The overall surgical mortality rate was 2% and the morbidity rate was higher than 29%. The local recurrence rate was 0% in the R1-R0 group vs. 50% in the R1 group (p = 0.02). Disease-free survival was 49 months in the R1-R0 group vs. 32 months in the R1 group (p = 0.6). Overall survival was 51 months for the R1-R0 group vs. 35 months for the R1 group (p = 0.5). Intraoperative extension of the positive surgical margin improved the local recurrence rate but was not associated with improvement in overall survival or disease-free survival and could possibly increase postoperative morbidity.

The aim of this study was to investigate the effect of heat sink on the recurrence of hepatic malignant tumors <3 cm after percutaneous radiofrequency ablation (RFA). This study included 564 hepatic malignant tumors <3 cm in 381 patients. Preoperative images were used to determine whether these tumors were adjacent to vessels, and the diameter of adjacent vessels was measured. RFA was performed computed tomography (CT), magnetic resonance imaging (MRI) and ultrasound (US) guidance, and postoperative imaging follow-up was then conducted. SPSS software version 17.0 was used for data processing, and the χ2 test was used for comparative analysis. Two-sided P < 0.05 indicated statistical significance. A total of 33 recurrences were found: 15 in the MR group (15/468), 12 in the US group (12/53), and 6 in the CT group (6/43). Of the 101 lesions adjacent to blood vessels larger than 3 mm, 20 showed recurrence: 10 in the MR group (10/77), 7 in the US group (7/17), and 3 in the CT group (3/7). The recurrence rate of perivascular lesions was higher than that of nonperivascular lesions, and the rate in the MR group was lower those in the US and CT groups. The curative effect of MRI-guided RFA is better than those of US- and CT-guided ablation. The heat sink effect is an important factor affecting recurrence of hepatic malignant tumors after RFA.

Management and recurrence of keratocystic odontogenic tumor: a systematic review.

The objective of this study was to evaluate the most up-to-date treatment modalities and respective recurrence rates for keratocystic odontogenic tumor (KCOT). A systematic review of the literature from 1999 to 2010 was undertaken examining treatment and recurrence rates for KCOT. Four inclusion criteria were defined for articles to then be analyzed against 8 standards. Of the 2736 published articles, 8 met the inclusion criteria. When merging the data, enucleation and enucleation with adjunctive measures (other than Carnoy's solution) had recurrence rates of 25.6% and 30.3%, respectively. Marsupialization with adjunctive measures produced a recurrence rate of 15.8%, whereas enucleation with Carnoy's solution presented a recurrence rate of 7.9%. Only one resection case had recurrence (6.3%). The enucleation technique with the use of adjunctive procedures (other than Carnoy's solution) provides a higher recurrence rate than any other treatment modality. Copyright © 2013 Elsevier Inc.

The optimal duration of antibiotic treatment for hematogenous vertebral osteomyelitis (HVO) should be based on the patient's risk of recurrence, but it is not well established. A retrospective review was conducted to evaluate the optimal duration of antibiotic treatment in patients with HVO at low and high risk of recurrence. Patients with at least 1 independent baseline risk factor for recurrence, determined by multivariable analysis, were considered as high risk and those with no risk factor as low risk. A total of 314 patients with microbiologically diagnosed HVO were evaluable for recurrence. In multivariable analysis, methicillin-resistant Staphylococcus aureus infection (adjusted odds ratio [aOR], 2.61; 95% confidence interval [CI], 1.16-5.87), undrained paravertebral/psoas abscesses (aOR, 4.09; 95% CI, 1.82-9.19), and end-stage renal disease (aOR, 6.58; 95% CI, 1.63-26.54) were independent baseline risk factors for recurrence. Therefore, 191 (60.8%) patients were classified as low risk and 123 (39.2%) as high risk. Among high-risk patients, there was a significant decreasing trend for recurrence according to total duration of antibiotic therapy: 34.8% (4-6 weeks [28-41 days]), 29.6% (6-8 weeks [42-55 days]), and 9.6% (≥8 weeks [≥56 days]) (P = .002). For low-risk patients, this association was still significant but the recurrence rates were much lower: 12.0% (4-6 weeks), 6.3% (6-8 weeks), and 2.2% (≥8 weeks) (P = .02). Antibiotic therapy of prolonged duration (≥8 weeks) should be given to patients with HVO at high risk of recurrence. For low-risk patients, a shorter duration (6-8 weeks) of pathogen-directed antibiotic therapy may be sufficient. © The Author 2016.

Background Two phase III trials of photodynamic therapy (PDT) with BF-200 ALA, a recently approved nanoemulsion formulation of 5-aminolaevulinic acid (ALA) demonstrated high clearance rates in mild-to-moderate actinic keratosis (AK). The comparison to a registered methyl aminolaevulinate (MAL) cream demonstrated significantly superior total patient clearance rates. Objectives To evaluate long-term efficacy and safety of PDT for AK 6 and 12 months after the last PDT with BF-200 ALA, MAL or placebo. Methods The follow-up phase (FUP) was performed with patients of two phase III studies. Both studies compared BF-200 ALA with placebo, one of the studies additionally with MAL. Overall recurrence rates and various subgroups (light source, lesion severity, lesion location, complete responders after first PDT) were assessed 6 and 12 months after the last PDT. Results Recurrence rates were similar for BF-200 ALA and MAL, with a tendency to lower recurrence rates for BF-200 ALA. The proportion of patients who were fully cleared during PDT and remained completely clear for at least 12 months after PDT were 47% for BF-200 ALA (both studies) and 36% for MAL treatment. The subgroup that was illuminated with narrow wavelength LED lamps reached 69% and 53% for BF-200 ALA (both studies, respectively) and 41% for MAL. No safety concerns were reported. Conclusions The FUP data confirmed the high efficacy and safety of PDT with BF-200 ALA. The slightly lower recurrence rates after BF-200 ALA treatment compared with MAL treatment enhanced the better treatment outcome due to the significantly superior efficacy. PMID:23252768

Cost data are useful in health planning, budgeting and for assessing the efficiency of services. However, such data are not easily available from developing countries. We therefore estimated the cost incurred for the year 1991-92 on a primary health centre in northern India, which is affiliated to an academic institution. The total costs incurred included the capital costs for land, building, furniture, vehicles and equipment as well as the recurrent costs for salaries, drugs and vaccines, diesel and maintenance. Except for land, where the 'opportunity cost' was calculated, the current market rates were considered for all other factors. A discount rate of 10% was used in the study. A total of Rs 777,015 (US $24,282) was incurred on the primary health centre in the study year, 80% being recurrent costs. Salaries constituted 62% of the total costs. A sum of Rs 30 (US $0.94) per head per year on primary health care was being incurred. Salaries constitute the bulk of the cost incurred on health. Approximately Rs 28 (40%) of the Rs 69 spent per head per year on health services by the Government of India is incurred on providing primary health care services.

Acute coronary syndrome (ACS) patients are at very high cardiovascular risk and tend to have recurrent cardiovascular events. The clinical indicators for subsequent cardiovascular events are limited and need further investigation. This study aimed to explore clinical indicators that were associated with recurrent cardiovascular events following index hospitalization. The data of patients hospitalized with ACS at a tertiary care hospital in northern Thailand between January 2009 and December 2012 were retrospectively reviewed from medical charts and the electronic hospital database. The patients were classified into three groups based on the frequency of recurrent cardiovascular events (nonfatal ACS, nonfatal stroke, or all-cause death) they suffered: no recurrent events (0), single recurrent event (1), and multiple recurrent events (≥2). Ordinal logistic regression was performed to explore the clinical indicators for recurrent cardiovascular events. A total of 405 patients were included; 60 % were male; the average age was 64.9 ± 11.5 years; 40 % underwent coronary revascularization during admission. Overall, 359 (88.6 %) had no recurrent events, 36 (8.9 %) had a single recurrent event, and 10 (2.5 %) had multiple recurrent events. The significant clinical indicators associated with recurrent cardiovascular events were achieving an LDL-C goal of < 70 mg/dL (Adjusted OR = 0.43; 95 % CI = 0.27-0.69, p-value < 0.001), undergoing revascularization during admission (Adjusted OR = 0.44; 95 % CI = 0.24-0.81, p-value = 0.009), being male (Adjusted OR = 1.85; 95 % CI = 1.29-2.66, p-value = 0.001), and decrease estimated glomerular filtration rate (Adjusted OR = 2.46; 95 % CI = 2.21-2.75, p-value < 0.001). The routine clinical practice indicators assessed in ACS patients that were associated with recurrent cardiovascular events were that achieving the LDL-C goal and revascularization are protective factors, while being male and having decreased estimated glomerular filtration rate are risk factors for recurrent cardiovascular events. These clinical indicators should be used for routinely monitoring patients to prevent recurrent cardiovascular events in ACS patients.

To evaluate the risk of recurrent intracranial hemorrhage (ICH) in patients on vitamin K antagonists (VKAs) after a first episode of ICH. The Cerebral Haemorrhage in patients Restarting Oral Anticoagulant Therapy (CHIRONE) Study collected data of patients eligible for the study from the database of 27 centers affiliated with the Italian Federation of Anticoagulation Clinics. We enrolled 267 patients (163 male, median age 73.9 years) who had received VKA anticoagulation after an ICH event. During the total period of follow-up (778 patient-years), ICH recurred in 20 patients (7.5%; rate 2.56 × 100 patient-years) at a median time of 16.5 months, and was fatal in 5 patients (25%; rate 0.4 × 100 patient-years). Male sex, hypertension, prosthetic valves, previous ischemic stroke, renal failure, cancer, and spontaneous events were associated with the risk of recurrence, though none of them in isolation reached statistical significance. More than one-third of spontaneous recurrences occurred in patients with a posttraumatic index event. Our results show that patients with a history of ICH carry a significant risk of recurrent ICH when treated with VKA anticoagulation. The risk is also present, though to a lower degree, in patients with previous posttraumatic events. All patients with a history of ICH require a careful evaluation of their thromboembolic risk to estimate the net clinical benefit of (re)starting anticoagulation with VKAs.

In depression, non-remission, recurrence of depressive episodes after remission and conversion to bipolar disorder are crucial determinants of poor outcome. The present study aimed to determine the cumulative incidences and clinical predictors of these long-term outcomes after the first lifetime episode of depression. A total of 301 in- or out-patients aged 18-70 years with a validated diagnosis of a single depressive episode were assessed from 2005 to 2007. At 5 years of follow-up, 262 patients were reassessed by means of the life chart method and diagnostic interviews from 2011 to 2013. Cumulative incidences and the influence of clinical variables on the rates of remission, recurrence and conversion to bipolar disorder, respectively, were estimated by survival analysis techniques. Within 5 years, 83.3% obtained remission, 31.5% experienced recurrence of depression and 8.6% converted to bipolar disorder (6.3% within the first 2 years). Non-remission increased with younger age, co-morbid anxiety and suicidal ideations. Recurrence increased with severity and treatment resistance of the first depression, and conversion to bipolar disorder with treatment resistance, a family history of affective disorder and co-morbid alcohol or drug abuse. The identified clinical characteristics of the first lifetime episode of depression should guide patients and clinicians for long-term individualized tailored treatment.

The US Preventive Services Task Force recommends low-dose aspirin for the prevention of preeclampsia among women at high risk for primary occurrence or recurrence of disease. Recommendations for the use of aspirin for preeclampsia prevention were issued by the US Preventive Services Task Force in September 2014. The objective of the study was to evaluate the incidence of recurrent preeclampsia in our cohort before and after the US Preventive Services Task Force recommendation for aspirin for preeclampsia prevention. This was a retrospective cohort study designed to evaluate the rates of recurrent preeclampsia among women with a history of preeclampsia. We utilized a 2-hospital, single academic institution database from August 2011 through June 2016. We excluded multiple gestations and included only the first delivery for women with multiple deliveries during the study period. The cohort of women with a history of preeclampsia were divided into 2 groups, before and after the release of the US Preventive Services Task Force 2014 recommendations. Potential confounders were accounted for in multivariate analyses, and relative risk and adjusted relative risk were calculated. A total of 17,256 deliveries occurred during the study period. A total of 417 women had a documented history of prior preeclampsia: 284 women before and 133 women after the US Preventive Services Task Force recommendation. Comparing the before and after groups, the proportion of Hispanic women in the after group was lower and the method of payment differed between the groups (P <.0001). The prevalence of type 1 diabetes was increased in the after period, but overall rates of pregestational diabetes were similar (6.3% before vs 5.3% after [P > .05]). Risk factors for recurrent preeclampsia included maternal age >35 years (relative risk, 1.83; 95% confidence interval, 1.34-2.48), Medicaid insurance (relative risk, 2.08; 95% confidence interval, 1.15-3.78), type 2 diabetes (relative risk, 2.13; 95% confidence interval, 1.37-3.33), and chronic hypertension (relative risk, 1.96; 95% confidence interval, 1.44-2.66). The risk of recurrent preeclampsia was decreased by 30% in the after group (adjusted relative risk, 0.70; 95% confidence interval, 0.52-0.95). Rates of recurrent preeclampsia among women with a history of preeclampsia decreased by 30% after release of the US Preventive Services Task Force recommendation for aspirin for preeclampsia prevention. Future prospective studies should include direct measures of aspirin compliance, gestational age at initiation, and explore the influence of race and ethnicity on the efficacy of this primary prevention.

Both Total and Subtotal Thyroidectomy are correct treatment options for symptomatic Euthyroid Multinodular Goitre. The choice depends upon surgeon's preference due to consideration of disadvantages like permanent hypothyroidism in Total Thyroidectomy and high chances of recurrence in Subtotal Thyroidectomy. Many surgeons believe that there is a higher incidence of Recurrent Laryngeal nerve injury in Total Thyroidectomy which affects their choice of surgery. This study aimed to compare the incidence of recurrent laryngeal nerve injury in total versus subtotal thyroidectomy. This non randomized controlled trial was carried out at Department of Surgery and ENT of Ayub Teaching Hospital Abbottabad, and Combined Military Hospital Rawalpindi from 1st September 2013 to 30th August 2014. During the period of study, patients presenting in surgical outpatient department with euthyroid multinodular goitre having pressure symptoms requiring thyroidectomy were divided into two groups by convenience sampling with 87 patients in group 1 and 90 patients in group 2. Group-1 was subjected to total thyroidectomy and Group -2 underwent subtotal thyroidectomy. All the patients had preoperative Indirect Laryngoscopy examination and it was repeated postoperatively to check for injury to the recurrent laryngeal nerve. A total of 177 patients were included in the study. Out of these, 87 patients underwent total thyroidectomy (Group-1). Two of these patients developed recurrent laryngeal nerve injury (2.3%). In group-2 subjected to subtotal thyroidectomy, three of the patients developed recurrent laryngeal nerve injury (3.3%). The p-value was 0.678. The overall risk of injury to this nerve in both surgeries combined was 2.8%. There is no significant difference in the risk of recurrent laryngeal nerve damage in patients undergoing total versus subtotal thyroidectomy.

Adolescent varicocele has been shown to affect spermatogenesis and correlate with decreased ipsilateral testicular volume, prompting treatment in a select population. We report our experience with 3 varicocele ligation procedures in concordance with sclerotherapy in adolescent patients. A total of 120 males underwent varicocele surgery at our institutions during an 8-year period. Sodium morrhuate sclerotherapy was used in 91 patients and 73 adolescent males fulfilled the 6-month followup criteria. The 73 males who were 9 to 17 years old underwent a total of 75 (bilateral in 2) procedures for varicocele treatment. Of the patients 23 underwent subinguinal microscopic varicocelectomy (group 1), 9 underwent loupe assisted subinguinal varicocelectomy (group 2) and 41 underwent loupe assisted inguinal varicocelectomy (group 3). All patients received intraoperative sclerotherapy using sodium morrhuate injection. Outcome measures included recurrence, complications and catch-up growth at a minimum of 6 months of followup. The varicocele recurrence rate was 2.7% in patients receiving combined surgical ligation and sclerotherapy ablation. Group 1 had 2 recurrent varicoceles and no hydrocele formation, group 2 had no varicocele recurrence and no hydrocele formation, and group 3 had no varicocele recurrence and 2 postoperative hydroceles. Catch-up growth in the ipsilateral testis was seen in 85% of patients. No atrophy or testicular loss was noted. This preliminary experience with combined surgical ligation and sclerotherapy ablation in the adolescent population resulted in low varicocele recurrence with minimal morbidity. Outcomes of loupe assisted varicocelectomy appear to be improved compared to those in previous studies, alluding to an advantage in the addition of sclerotherapy.

Abstract Our study sought to determine whether the size of the residual apical pleural space in young patients with primary spontaneous pneumothorax (PSP) following video-assisted thoracoscopic surgery is associated with the risk of recurrence. We retrospectively reviewed patients (≤30 years’ old) with primary spontaneous pneumothorax following thoracoscopic surgery (2002–2010) in a university-affiliated hospital. The size of residual apical pleural space was estimated by measuring the apex-to-cupola distance on a postoperative chest radiograph at 2 time windows: first between postoperative day (POD) 0 and 3, and second between POD 4 and 14. A total of 149 patients were enrolled with a median follow-up of 11.2 months (interquartile range, 0.95–29.5 months), of whom 141 (94.6%) were male with a mean age of 20 years. The postoperative recurrence rate was 11.4%. Comparing the characteristics between the patients with and without recurrent pneumothorax, the patients with recurrence were younger (18.2 + 2.4 vs 20.7 + 3.7 years, P = 0.008), with a lower rate of pleurodesis (35% vs1 69%, P = 0.037), longer apex-to-cupola distance at POD 0 to 3 (22.41 ± 19.56 vs 10.07 ± 10.83 mm, P < 0.001) and POD 4 to 14 (11.82 ± 9.75 vs 5.54 ± 8.38 mm, P = 0.005) than the patients without recurrence. In a multivariate logistic regression model for recurrent pneumothorax, age <18 years (P = 0.026, odds ratio [OR]: 4.694), apex-to-cupola distance at POD 0 to 3 >10 mm (P = 0.027, OR: 5.319), and no pleurodesis during VATS (P = 0.022, OR: 5.042) were independent risk factors for recurrent pneumothorax. The recurrence rate was not low (11.4%) in young patients with PSP following VATS. Residual apical pleural space with apex-to-cupola distance of 10 mm or greater at POD 0 to 3, younger age, and no pleurodesis would increase postoperative recurrence of primary spontaneous pneumothorax.

There is no consensus on the optimal method of stabilization (arthroscopic or open) in collision athletes with anterior shoulder instability. To examine the effect of "subcritical" bone loss and football-specific exposure on the rate of recurrent shoulder instability after arthroscopic stabilization in an intercollegiate American football population. Case-control study; Level of evidence, 3. Fifty intercollegiate football players underwent primary arthroscopic stabilization for anterior shoulder instability and returned to football for at least a single season. Preoperatively, 32 patients experienced recurrent subluxations, and 18 patients experienced a single or recurrent dislocation. Shoulders with glenoid bone loss >20%, an engaging Hill-Sachs lesion, an off-track lesion, and concomitant rotator cuff repair were excluded from the study. The primary outcome of interest was the ability to return to football without subsequent instability. Patients were followed for time to a subsequent instability event after return to play using days of exposure to football and total follow-up time after arthroscopic stabilization. Fifty consecutive patients returned to American football for a mean 1.5 seasons (range, 1-3) after arthroscopic stabilization. Three of 50 (6%; 95% CI, 1.3%-16.5%) patients experienced recurrent instability. There were no subsequent instability events after a mean 3.2 years of military service. All shoulders with glenoid bone loss >13.5% (n = 3) that underwent arthroscopic stabilization experienced recurrent instability upon returning to sport, while none of the shoulders with <13.5% glenoid bone loss (n = 47) sustained a recurrent instability event during football ( X 2 = 15.80, P < .001). Shoulders with >13.5% glenoid bone loss had an incidence rate of 5.31 cases of recurrent instability per 1000 athlete-exposures of football. In 72,000 athlete-exposures to football with <13.5% glenoid bone loss, there was no recurrent instability. Significantly more anchors were used during the primary arthroscopic stabilization procedure in patients who experienced multiple preoperative instability events ( P = .005), and lesions spanned significantly more extensive portions along the circumference of the glenoid ( P = .001) compared with shoulders having a single preoperative instability event before surgical stabilization. Arthroscopic stabilization of anterior shoulder instability in American football players with <13.5% glenoid bone loss provides reliable outcomes and low recurrence rates.

Cervical cancer (CC) is one of the most common cancers in women and virtually all cases of CC are a result of a persistent infection of human papillomavirus (HPV). For disease detected in early stages there is curing treatment but when diagnosed late with recurring disease and metastasis there are limited possibilities. Here we evaluate HPV impact on treatment resistance and metastatic disease progression. Prevalence and distribution of HPV genotypes and HPV16 variants in a Swedish CC patient cohort (n=209) was evaluated, as well as HPV influence on patient prognosis. Tumor samples suitable for analysis (n=204) were genotyped using two different real-time PCR methods. HPV16 variant analysis was made using pyrosequencing. Results showed that HPV prevalence in the total series was 93%. Of the HPV-positive samples, 13% contained multiple infections, typically with two high-risk HPV together. Primary cure rate for the complete series was 95%. Recurrence rate of the complete series was 28% and distant recurrences were most frequent (20%). Patients with tumors containing multiple HPV-strains and particularly HPV genotypes belonging to the alpha 7 and 9 species together had a significantly higher rate of distant tumor recurrences and worse cancer-specific survival rate.

Sutureless total thyroidectomy by using vessel sealing devices has been shown to be safe in some recent clinical studies. However, some surgeons are still concerned about the use of these energy devices in the vicinity of there current laryngeal nerve and parathyroid glands. The objective of this study was to investigate the effects of the use of pure LigaSure on postoperative complications and to discuss the pertinent literature. A total of 456 patients having undergone a total thyroidectomy operation between June 2009 and March 2011 were included in the study. Data were prospectively collected and retrospectively evaluated. Patients were separated into 2 groups. Group L comprised of 182 patients where onlyLigaSure was used, and group LT consisted of 274 patients where ligation was used in the vicinity of the recurrent laryngeal nerve and parathyroid glands, and LigaSure was used in all other parts of the surgery. Patient's blood calcium values were checked preoperatively and at postoperative 24, 48, and 72 hours. Groups were assessed in terms of demographic properties, thyroid pathology, duration of operation, and postoperative complications. Groups were similar in respect of demographic properties, operation duration, thyroid gland pathology. No mortality rate was recorded. Laboratory hypocalcemia rate was higher in group L (P 0.003), but no significant difference was identified between groups in terms of symptomatic hypocalcemia.No permanent hypocalcemia or recurrent laryngeal nerve injury developed in any of the patients in the two groups. Pure LigaSure for total thyroidectomy may increase laboratory hypocalcemia rate, but not symptomatic hypocalcemia. Hemorrhage related complications were similar and low in the two groups. Ligations in the places close to delicate anatomic structures did not cause longer operative times and may be a safer option in total thyroidectomy. Celsius.

In a complete geographic series of 294 cases of primary vulvar carcinomas prophylactic inguinal-femoral irradiation was used as a standard postoperative therapy. Inguinal lymph node dissection was performed in only 27 cases (9%) and was not part of the standard surgery. The histology was squamous cell carcinoma in 269 cases (92%). The primary surgery was total vulvectomy, partial vulvectomy, or local resection of the tumor. The main type of radiotherapy was adjuvant inguinal irradiation. Two separate, symmetrical and rectangular inguinal fields were irradiated with combined photon and electron beams. In the complete series 127 recurrences (43%) were recorded. Local (24%) and regional recurrences (19%) were most frequent. Type of surgery was not associated with the risk of tumor recurrence. The 5-year overall survival rate was 53% and the relapse-free survival (RFS) rate was 55%. Tumor grade was significantly (P=0.007) associated with the RFS. The inguinal RFS rate was 75% both for patients treated with adjuvant inguinal irradiation without lymphadenectomy and patients treated with primary lymph adenectomy +/- inguinal irradiation. Postoperative complications were recorded in 22%. Postoperative complications occurred most frequently in the subgroup undergoing inguinal lymphadenectomy. Chronic lymph edemas were the most serious late tissue reactions.

BACKGROUND: Lipomas are the most frequent soft -tissue tumors arising from adipose tissue. Traditionally, open surgery is a mainstay of their treatment. Recently, new treatment modalities emerge in order to decrease morbidity, to increase satisfaction rate in patents, but not to raise recurrence risk at the same time. AIM: The aim of this article is to present our experience with liposuction assisted lipoma removal in terms of efficacy, complications, risk of recurrence and patient satisfaction. METHODS: The study was prospective in which treated lipomas with vacuum suction were analyzed. Preoperative diagnosis comprised clinical exam and additional diagnostic tools as to rule out malignancy. Subcutaneous lipomas with diameter of at least 5 cm were taken into account. Tumescent liposuction technique with modification was used. RESULTS: Lipoma’s size, distribution and demographics are given. Total removal with affordable rate of complication was achieved in each case. No recurrences in 12 months follow-up period were seen. Satisfaction rate in patients was high. CONCLUSION: Liposuction assisted lipoma removal is a good alternative to open approach lipectomy and we would recommend its use in selected cases where, it might be more advantageous. However, prospective randomized controlled studies are needed in order to estimate its accurate clinical value. PMID:29104686

The surgical management of fistula-in-ano is still debatable and no clear recommendations have been made available until now. The present study analyses the results of ligation of intersphincteric fistula tract (LIFT) technique in treating fistula-in-ano in particular with recurrence, healing time, and continence status. LIFT in the management of patients of fistula-in-ano of cryptoglandular origin. Prospective study. This is a prospective study of 52 patients admitted from September 2012 to August 2014. Patients were managed with LIFT technique and results of LIFT technique were compared with other studies in terms of recurrence rate, incontinence rate, and other postoperative complications. A total of 52 patients were studied. Median follow-up was 24 weeks. Primary healing was achieved in 32 (71.11%) patients. Thirteen patients (28.88%) had a recurrence. No patient reported any subjective decrease incontinence after the procedure. LIFT technique is simple and easy to learn. With this method fistula-in-ano could be easily treated even at primary health care level. LIFT technique is a simple and novel modified approach for the treatment of fistula-in-ano with rapid healing rate and without any resultant incontinence.

In thyroidectomy, little has been reported on the differential recurrent laryngeal nerve (RLN) palsy rates between the left and right sides. Even less is known about the potential differences causing these differential rates. This study reports the left versus right RLN palsy rates of total thyroidectomy cases in a single institution, relating them to the comparative stiffness of the left and right porcine RLNs. Computed stress modelling was also used to estimate the differential levels of tension within each RLN. For the comparison of the left and right RLN palsy rates, 1926 cases of total thyroidectomy (between 2007 and 2013) from the Monash University Endocrine Surgery Unit were included. Stiffness of porcine RLNs was experimentally determined by measuring nerve extension against incremental increase in load. Additionally, the tension of intraoperatively stretched RLNs was estimated by computer modelling. The left RLN had a palsy rate of 0.9% (18/1926), which was significantly lower (P = 0.025) than the right RLN palsy rate of 1.8% (34/1926). The left porcine RLN was 22% stiffer than the right RLN (P = 0.004). The stress modelling estimated that at the apex of the artificial RLN genu during anteromedial rotation of the thyroid lobe, the right RLN experiences twice the tension experienced by the left RLN. The stiffer left RLN and the higher tension generated in the right RLN during thyroidectomy may jointly contribute to the higher right RLN palsy rate. © 2015 Royal Australasian College of Surgeons.

The present study was performed to evaluate the significance of biologic subtype and 21-gene recurrence score relative to local recurrence and local-regional recurrence after breast conservation treatment with radiation. Eastern Cooperative Oncology Group E2197 was a prospective randomized clinical trial that compared two adjuvant systemic chemotherapy regimens for patients with operable breast carcinoma with 1-3 positive lymph nodes or negative lymph nodes with tumor size >1.0 cm. The study population was a subset of 388 patients with known 21-gene recurrence score and treated with breast conservation surgery, systemic chemotherapy, and definitive radiation treatment. Median follow-up was 9.7 years (range = 3.7-11.6 years). The 10-year rates of local recurrence and local-regional recurrence were 5.4 % and 6.6 %, respectively. Neither biologic subtype nor 21-gene Recurrence Score was associated with local recurrence or local-regional recurrence on univariate or multivariate analyses (all P ≥ 0.12). The 10-year rates of local recurrence were 4.9 % for hormone receptor positive, HER2-negative tumors, 6.0 % for triple negative tumors, and 6.4 % for HER2-positive tumors (P = 0.76), and the 10-year rates of local-regional recurrence were 6.3, 6.9, and 7.2 %, respectively (P = 0.79). For hormone receptor-positive tumors, the 10-year rates of local recurrence were 3.2, 2.9, and 10.1 % for low, intermediate, and high 21-gene recurrence score, respectively (P = 0.17), and the 10-year rates of local-regional recurrence were 3.8, 5.1, and 12.0 %, respectively (P = 0.12). For hormone receptor-positive tumors, the 21-gene recurrence score evaluated as a continuous variable was significant for local-regional recurrence (hazard ratio 2.66; P = 0.03). The 10-year rates of local recurrence and local-regional recurrence were reasonably low in all subsets of patients. Neither biologic subtype nor 21-gene recurrence score should preclude breast conservation treatment with radiation.

Management of intracranial chordomas remains challenging, despite improvements in microsurgical techniques and radiotherapy. Here, we analyzed the prognostic factors associated with improved rates of tumor control in patients with intracranial chordomas, who received either gross (GTR) or subtotal resections (STR). A retrospective review was performed to identify all patients who were undergoing resection of their intracranial chordomas at the Ronald Reagan University of California Los Angeles Medical Center from 1990 to 2011. In total, 57 patients undergoing 81 resections were included. There were 24 females and 33 males with a mean age of 44.6 years, and the mean tumor diameter was 3.36 cm. The extent of resection was not associated with recurrence. For all 81 operations, the 1 and 5 year progression free survival (PFS) was 87.5 and 40.4%, and 88.0 and 33.6% for STR and GTR, respectively (p=0.90). Adjuvant radiotherapy was associated with improved rates of PFS (hazard ratio [HR] 0.20; p=0.009). Additionally, age >45 years (HR 5.88; p=0.01) and the presence of visual deficits (HR 7.59; p=0.03) were associated with worse rates of tumor control. Tumor size, sex, tumor histology, and recurrent tumors were not predictors of recurrence. Younger age, lack of visual symptoms on presentation and adjuvant radiotherapy were associated with improved rates of tumor control following surgery. However, GTR and STR produced comparable rates of tumor control. The surgical management of intracranial chordomas should take a conservative approach, with the aim of maximal but safe cytoreductive resection with adjuvant radiation therapy, and a major focus on quality of life.

Although endoscopic submucosal dissection (ESD) is a widely accepted treatment for early gastric cancer (EGC), there is no consensus regarding the management of positive horizontal margin (HM) despite en bloc ESD. The aim of the current study was to identify the risk factors and optimal management of positive HM in EGCs resected by en bloc ESD. A total of 890 consecutive patients with 1,053 intramucosal EGCs resected by en bloc ESD between April 2005 and June 2011. Clinicopathological data were retrieved retrospectively to assess the positive HM rate, local recurrence rate, risk factors for positive HM, and outcomes of treatment for local recurrent tumor. Positive HM was defined as a margin with direct tumor invasion (type A), the presence of cancerous cells on either end of 2-mm-thick cut sections (type B), or an unclear tumor margin resulting from crush or burn damage (type C). The positive HM rate was 2.0% (21/1,053). The local recurrence rate was 0.3% (3/1,053). All local recurrent tumors were intramucosal carcinomas, and were resected curatively by re-ESD. Multivariate analysis with logistic regression showed tumor location in the upper third of the stomach and lesions not matching the absolute indication to be independent risk factors for positive HM. The risk factors for HM positivity in cases of EGC resected by en bloc ESD are tumor location in the upper third of the stomach and dissatisfaction of the absolute indication for curative ESD.

To compare the analysis of chromosome number from paraffin-embedded products of conception using single-nucleotide polymorphism (SNP) microarray with the recommended screening for the evaluation of couples presenting with recurrent pregnancy loss who do not have previous fetal cytogenetic data. We performed a retrospective cohort study including all women who presented for a new evaluation of recurrent pregnancy loss over a 2-year period (January 1, 2012, to December 31, 2013). All participants had at least two documented first-trimester losses and both the recommended screening tests and SNP microarray performed on at least one paraffin-embedded products of conception sample. Single-nucleotide polymorphism microarray identifies all 24 chromosomes (22 autosomes, X, and Y). Forty-two women with a total of 178 losses were included in the study. Paraffin-embedded products of conception from 62 losses were sent for SNP microarray. Single-nucleotide polymorphism microarray successfully diagnosed fetal chromosome number in 71% (44/62) of samples, of which 43% (19/44) were euploid and 57% (25/44) were noneuploid. Seven of 42 (17%) participants had abnormalities on recurrent pregnancy loss screening. The per-person detection rate for a cause of pregnancy loss was significantly higher in the SNP microarray (0.50; 95% confidence interval [CI] 0.36-0.64) compared with recurrent pregnancy loss evaluation (0.17; 95% CI 0.08-0.31) (P=.002). Participants with one or more euploid loss identified on paraffin-embedded products of conception were significantly more likely to have an abnormality on recurrent pregnancy loss screening than those with only noneuploid results (P=.028). The significance remained when controlling for age, number of losses, number of samples, and total pregnancies. These results suggest that SNP microarray testing of paraffin-embedded products of conception is a valuable tool for the evaluation of recurrent pregnancy loss in patients without prior fetal cytogenetic results. Recommended recurrent pregnancy loss screening was unnecessary in almost half the patients in our study. II.

AIM: To define the histopathological features predictive of post-transplant hepatocellular carcinoma (HCC) recurrence after transarterial chemoembolization, applicable for recipient risk stratification. METHODS: We retrospectively reviewed the specimens of all suspicious nodules (total 275) from 101 consecutive liver transplant recipients which came to our Pathology Unit over a 6-year period. All nodules were sampled and analyzed, and follow-up data were collected. We finally considered 11 histological variables for each patient: total number of nodules, number of viable nodules, size of the major nodule, size of the major viable nodule, occurrence of microscopic vascular invasion, maximum Edmondson's grade, clear cell/sarcomatous changes, and the residual neoplastic volume. Survival data were computed by means of the Kaplan-Meier procedure and analyzed by means of the Cox proportional hazards model. The multivariate linear regression and a k-means cluster analysis were also used in order to compute the standardized histological score. RESULTS: The total number of nodules, the residual neoplastic volume (the total volume of all evaluated nodules minus the necrotic portion) and the microvascular invasion entered the Cox multivariate hazard model with HCC recurrence as dependent variable. The histological score was therefore computed and a cluster analysis sorted recipients into 3 risk groups, with 3.3%, 18.5% and 53.8% respectively of tumor recurrence rates and 1.6%, 11.1% and 38.5% of tumor-related mortality respectively at the end of follow-up. CONCLUSION: The histological score allows a reliable stratification of HCC recurrence risk, especially in those recipients found out to be beyond the Milan criteria after orthotopic liver transplantation (OLT).

A fortuitous exposure of the East Paradise fault zone near Arroyo de las Calabacillas has helped us determine a post-middle Pleistocene history for a long-forgotten Quaternary fault in the City of Albuquerque, New Mexico. Mapping of two exposures of the fault zone allowed us to measure a total vertical offset of 2.75 m across middle Pleistocene fluvial and eolian deposits and to estimate individual surface-faulting events of about 1, 0.5, and 1.25 m. These measurements and several thermoluminescence ages allow us to calculate a long-term average slip rate of 0.01 ± 0.001 mm/yr and date two surface-faulting events to 208 ± 25 ka and 75 ± 7 ka. The youngest event probably occurred in the late Pleistocene, sometime after 75 ± 7 ka. These data yield a single recurrence interval of 133 ± 26 ka and an average recurrence interval of 90 ± 10 ka. However, recurrence intervals are highly variable because the two youngest events occurred in less than 75 ka. Offsets of 0.5-1.25 m and a fault length of 13-20 km indicate that surface-rupturing paleoearthquakes on the East Paradise fault zone had probable Ms or Mw magnitudes of 6.8-7.0. Although recurrence intervals are long on the East Paradise fault zone, these data are significant because they represent some of the first published slip rate, paleoearthquake magnitude, and recurrence information for any of the numerous Quaternary faults in the rapidly growing Albuquerque-Rio Rancho metropolitan area.

The 21-gene recurrence score (RS) assay quantifies the likelihood of distant recurrence in women with estrogen receptor-positive, lymph node-negative breast cancer treated with adjuvant tamoxifen. The relationship between the RS and chemotherapy benefit is not known. The RS was measured in tumors from the tamoxifen-treated and tamoxifen plus chemotherapy-treated patients in the National Surgical Adjuvant Breast and Bowel Project (NSABP) B20 trial. Cox proportional hazards models were utilized to test for interaction between chemotherapy treatment and the RS. A total of 651 patients were assessable (227 randomly assigned to tamoxifen and 424 randomly assigned to tamoxifen plus chemotherapy). The test for interaction between chemotherapy treatment and RS was statistically significant (P = .038). Patients with high-RS (> or = 31) tumors (ie, high risk of recurrence) had a large benefit from chemotherapy (relative risk, 0.26; 95% CI, 0.13 to 0.53; absolute decrease in 10-year distant recurrence rate: mean, 27.6%; SE, 8.0%). Patients with low-RS (< 18) tumors derived minimal, if any, benefit from chemotherapy treatment (relative risk, 1.31; 95% CI, 0.46 to 3.78; absolute decrease in distant recurrence rate at 10 years: mean, -1.1%; SE, 2.2%). Patients with intermediate-RS tumors did not appear to have a large benefit, but the uncertainty in the estimate can not exclude a clinically important benefit. The RS assay not only quantifies the likelihood of breast cancer recurrence in women with node-negative, estrogen receptor-positive breast cancer, but also predicts the magnitude of chemotherapy benefit.

Microwave ablation is an in situ method of tumour destruction used to treat patients with unresectable liver tumours. A new microwave generator and probe, designed to deliver high energy into solid tumours quickly has been developed at our institution. We report the results of its use in patients with unresectable liver tumours treated by a single surgeon in a single institution. Thirty-one patients with 89 unresectable liver tumours were recruited into the study and underwent microwave ablation in a single procedure. There were no post-operative complications. At a median of 24 months post ablation, 15 patients were alive with 7 patients disease free. At a median of 26 months, 8 patients were alive with tumour recurrence but only 1 with local recurrence. The remaining 7 patients with recurrence were found to have new disease at locations remote from the ablation site. Fourteen patients died of disease progression at a median survival of 15 months, with only 1 patient with local and remote tumour recurrence. Of the total numbers of tumours treated (n=89), a local tumour recurrence rate of 2% was observed. Overall median survival was 29 months with 3 year survival of 40%. Microwave tissue ablation using this novel generator and probe has a low local recurrence and complication rate. Overall survival is comparable to alternative ablation modalities and its ability to treat, even large tumours, with a single insertion of the probe makes it an extremely attractive treatment option.

The role of surgery for acute patellar dislocation without osteochondral fracture is controversial. The aim of this study was to report the short-term results of management of patellar dislocation in our institute. Patients who were seen in our institution with patella dislocation from January 2011 to April 2014 were managed according to a standardised management algorithm. Pretreatment and 1-year post-treatment International Knee Documentation Committee score, Tegner activity level scale score, and presence of apprehension sign were analysed. A total of 41 patients were studied of whom 20 were first-time dislocators and 21 were recurrent dislocators. Among the first-time dislocators, there was a significant difference between patients who received conservative treatment versus surgical management. The conservative treatment group had a 33% recurrent dislocation rate, whereas there were no recurrent dislocations in the surgery group. There was no difference in Tegner activity level scale score or apprehension sign before and 1 year after treatment, however. Among the recurrent dislocators, there was a significant difference between those who received conservative treatment and those who underwent surgery. The recurrent dislocation rate was 71% in the conservative treatment group versus 0% in the surgery group. There was also significant improvement in International Knee Documentation Committee score from 67.7 to 80.0 (P=0.02), and of apprehension sign from 62% to 0% (P<0.01). A management algorithm for patellar dislocation is described. Surgery is preferable to conservative treatment in patients who have recurrent patellar dislocation, and may also be preferable for those who have an acute dislocation.

The effect of coexistent chronic lymphocytic thyroiditis (CLT) on prognosis in papillary thyroid carcinoma (PTC) patients remains controversial. We evaluated the influence of coexistent CLT on prognostic outcome and the association of coexistent CLT with clinicopathological parameters. A retrospective study with a median follow-up of 70 months. Patients with PTC who underwent total thyroidectomy followed by (131)I remnant ablation between 1995 and 2003 at Asan Medical Center, Seoul, Korea were enrolled. CLT was diagnosed histopathologically. Among 1441 patients, 214 (14.9%) had coexistent CLT. A greater female preponderance was noted in the patients with CLT compared with those without CLT (P < 0.01). Mean tumour size in the patients with CLT was smaller than that in patients without CLT (2.0 +/- 1.2 vs. 2.2 +/- 1.4 cm; P = 0.02). One hundred and fifty-one (12.3%) patients without CLT had recurrence, whereas 14 (7.1%) patients with CLT had recurrence during the follow-up period (P = 0.016). In patients with cervical lymph node metastases, those with coexistent CLT showed a significantly lower recurrence rate than those without CLT (P = 0.012). However, this association was lost on multivariate analysis adjusting for other clinicopathological predictors for recurrence. In this study, CLT was commonly associated with PTC and was associated with smaller size of the primary tumour at presentation. CLT was also associated with a reduced risk of recurrence during follow-up, although this was not significant after adjustment for other prognostic factors.

In Japan and other societies with rapidly aging populations, recurrent pneumonia (RP) is a major clinical problem yet only limited information exists regarding the burden of this disease. A prospective study of adult pneumonia was conducted to investigate the incidence of RP and potential risk factors. From February 1, 2012 to January 31, 2013, patients aged ≥ 15 years who were diagnosed with pneumonia were prospectively enrolled in a representative community hospital located in central Japan. Patients were followed for one-year to evaluate the recurrence of pneumonia and characteristics associated with RP. Cox proportional hazards models were constructed to compute adjusted hazard ratios (aHR) and ascertain risk factors significantly associated with RP. In total, 841 patients with a median age of 73 years (range 15-101 years) were enrolled totaling 1,048 person-years of observation with a median follow-up time of 475 days. A total of 137 patients had at least one recurrent episode with an incidence rate of 13.1 per 100 person-years (95% confidence interval: 11.1-15.5). In multivariate analysis, a past history of pneumonia (aHR 1.95, 95% CI: 1.35-2.8), chronic pulmonary disease (aHR 1.86, 1.24-2.78) and inhaled corticosteroid usage (aHR 1.78, 1.12-2.84) and hypnotic/sedative medication usage (aHR 2.06, 1.28-3.31) were identified as independent risk factors for recurrent pneumonia, whereas angiotensin converting enzyme-inhibitors usage was associated with a reduction of the risk of RP (aHR 0.22, 0.05-0.91). The detection of P. aeruginosa was significantly associated with RP even after adjusting for chronic pulmonary diseases (aHR = 2.37). Recurrent pneumonia constitutes a considerable proportion of the pneumonia burden in Japan. A past history of pneumonia, chronic pulmonary disease, inhaled corticosteroid and hypnotic/sedative medication usage and detection of P. aeruginosa were identified as independent risk factors for recurrent pneumonia and special attention regarding the use of medications in this vulnerable population is needed to reduce the impact of this disease in aging populations.

The study aimed to identify the clinical characteristics of coexisting chronic lymphocytic thyroiditis (CLT) in papillary thyroid carcinoma (PTC) and to evaluate the influence on prognosis. A total of 1,357 patients who underwent thyroid surgery for PTC were included. The clinicopathological characteristics were identified. Patients who underwent total thyroidectomy (n = 597) were studied to evaluate the influence of coexistent CLT on prognosis. Among the total 1,357 patients, 359 (26.5%) had coexistent CLT. In the CLT group, the prevalence of females was higher than in the control group without CLT (P < 0.001). Mean tumor size and mean age in the patients with CLT were smaller than without CLT (P = 0.040, P = 0.047, respectively). Extrathyroidal extension in the patients with CLT was significantly lower than without CLT (P = 0.016). Among the subset of 597 patients, disease-free survival rate in the patients with CLT was significantly higher than without CLT (P = 0.042). However, the multivariate analysis did not reveal a negative association between CLT coexistence and recurrence. Patients with CLT display a greater female preponderance, smaller size, younger and lower extrathyroidal extension. CLT is not a significant independent negative predictive factor for recurrence, although presence of CLT indicates a reduced risk of recurrence.

Prior studies have identified risk factors for recurrent Clostridium difficile infection (CDI), but few studies have integrated these factors into a clinical prediction rule that can aid clinical decision-making. The objectives of this study were to derive and validate a CDI recurrence prediction rule to identify patients at risk for first recurrence in a national cohort of veterans. Retrospective cohort study. Veterans Affairs Informatics and Computing Infrastructure. A total of 22,615 adult Veterans Health Administration beneficiaries with first-episode CDI between October 1, 2002, and September 30, 2014; of these patients, 7538 were assigned to the derivation cohort and 15,077 to the validation cohort. A 60-day CDI recurrence prediction rule was created in a derivation cohort using backward logistic regression. Those variables significant at p<0.01 were assigned an integer score proportional to the regression coefficient. The model was then validated in the derivation cohort and a separate validation cohort. Patients were then split into three risk categories, and rates of recurrence were described for each category. The CDI recurrence prediction rule included the following predictor variables with their respective point values: prior third- and fourth-generation cephalosporins (1 point), prior proton pump inhibitors (1 point), prior antidiarrheals (1 point), nonsevere CDI (2 points), and community-onset CDI (3 points). In the derivation cohort, the 60-day CDI recurrence risk for each score ranged from 7.5% (0 points) to 57.9% (8 points). The risk score was strongly correlated with recurrence (R 2  = 0.94). Patients were split into low-risk (0-2 points), medium-risk (3-5 points), and high-risk (6-8 points) classes and had the following recurrence rates: 8.9%, 20.2%, and 35.0%, respectively. Findings were similar in the validation cohort. Several CDI and patient-specific factors were independently associated with 60-day CDI recurrence risk. When integrated into a clinical prediction rule, higher risk scores and risk classes were strongly correlated with CDI recurrence. This clinical prediction rule can be used by providers to identify patients at high risk for CDI recurrence and help guide preventive strategy decisions, while accounting for clinical judgment. © 2018 Pharmacotherapy Publications, Inc.

The optimal management of craniopharyngioma is still controversial. The aim of this study is to explore microsurgical outcomes of craniopharyngioma in 335 cases. Clinical data of 335 consecutive patients with craniopharyngioma between March 2011 and March 2017 were retrospectively analyzed. Gross total resection (GTR) was achieved in 265 cases (79.1%), subtotal resection (STR) was obtained in 70 cases (20.9%). The GTR rate was 81.93% in pediatric group and 78.17% in adult group respectively, no significant difference regarding the GTR rate was found in adult group compared with in pediatric group (p > 0.05). However, there was a noticeable difference in the elevated hypothalamic obesity in children group compared with in adult group after operation (p < 0.05). Multivariate analysis indicated that the tumor recurrence and surgical times played a negative role in the resection extent, the odds ratio and 95% confidence interval of the tumor recurrence and surgical times is [0.306 (0.155-0.603), (p < 0.01)] and [2.135 (1.101-4.142), (p < 0.05)] respectively. There was significant difference on panhypopituitarism between GTR and STR group (p < 0.05). However, No significant difference regarding the postoperative visual dysfunction and indepent quality of life respectively between GTR and STR group was found (p > 0.05). Additionally, there were no statistically significant differences for recurrence-free curves between GTR and STR plus adjuvant radiotherapy (p > 0.05). Present findings demonstrated that tumor recurrence and surgical times contribute to negative total resection for craniopharyngioma. Postoperative precise adjuvant radiotherapy was considered in selected cases if pursuit of GTR was rather dangerous under disadvantageous removal factors. Copyright © 2018 Elsevier B.V.

To review the surgical approaches, techniques, outcomes, and recurrence rates in a series of 80 olfactory groove meningioma (OGM) patients operated on between 1990 and 2003. Eighty patients underwent 81 OGM surgeries. Tumor diameter varied from 2 to 9 cm (average, 4.6 cm). In 35 surgeries (43.2%), the tumor was removed through bifrontal craniotomy; nine operations (11.1%) were performed through a unilateral subfrontal approach; 18 surgeries (22.2%) were performed through a pterional approach; seven surgeries (8.6%) were carried out using a fronto-orbital craniotomy; and 12 procedures (14.8%) were accomplished via a subcranial approach. Nine patients (11.3%) had undergone surgery previously and had recurrent tumor. Total removal was obtained in 72 patients (90.0%); subtotal removal was achieved in 8 patients (10.0%). Two patients, one with total and one with subtotal removal, had atypical (World Health Organization Grade II) meningiomas, whereas 78 patients had World Health Organization Grade I tumors. There was no operative mortality and no new permanent focal neurological deficit besides anosmia. Twenty-five patients (31.3%) experienced surgery-related complications. There were no recurrences in 75 patients (93.8%) 6 to 164 months (mean, 70.8 mo) after surgery. Three patients (3.8%) were lost to follow-up. In two patients (2.5%) with subtotal removal, the residual evidenced growth on computed tomography and/or magnetic resonance imaging 1 year after surgery. One of them had an atypical meningioma. The second, a multiple meningiomata patient, was operated on twice in this series. A variety of surgical approaches are used for OGM resection. An approach tailored to the tumor's size, location, and extension, combined with modern microsurgical cranial base techniques, allows full OGM removal with minimal permanent morbidity, excellent neurological outcome, and very low recurrence rates.

Purpose Antivascular endothelial growth factor (anti-VEGF) therapy is a promising treatment approach for patients with recurrent glioblastoma. This single-arm phase II study evaluated the efficacy of aflibercept (VEGF Trap), a recombinantly produced fusion protein that scavenges both VEGF and placental growth factor in patients with recurrent malignant glioma. Patients and Methods Forty-two patients with glioblastoma and 16 patients with anaplastic glioma who had received concurrent radiation and temozolomide and adjuvant temozolomide were enrolled at first relapse. Aflibercept 4 mg/kg was administered intravenously on day 1 of every 2-week cycle. Results The 6-month progression-free survival rate was 7.7% for the glioblastoma cohort and 25% for patients with anaplastic glioma. Overall radiographic response rate was 24% (18% for glioblastoma and 44% for anaplastic glioma). The median progression-free survival was 24 weeks for patients with anaplastic glioma (95% CI, 5 to 31 weeks) and 12 weeks for patients with glioblastoma (95% CI, 8 to 16 weeks). A total of 14 patients (25%) were removed from the study for toxicity, on average less than 2 months from treatment initiation. The main treatment-related National Cancer Institute Common Terminology Criteria grades 3 and 4 adverse events (38 total) included fatigue, hypertension, and lymphopenia. Two grade 4 CNS ischemias and one grade 4 systemic hemorrhage were reported. Aflibercept rapidly decreases permeability on dynamic contrast enhanced magnetic resonance imaging, and molecular analysis of baseline tumor tissue identified tumor-associated markers of response and resistance. Conclusion Aflibercept monotherapy has moderate toxicity and minimal evidence of single-agent activity in unselected patients with recurrent malignant glioma. PMID:21606416

OBJECTIVES: Our purpose was to compare the efficacy, complications, success rate, recurrence rate at 1 year, and crossovers of rubber band ligation (RBL) with those of bipolar electrocoagulation (BPEC) treatment for chronically bleeding internal hemorrhoids. METHODS: A total of 45 patients of mean age 51.5 years, who had rectal bleeding from grade II or III hemorrhoids and in whom intensive medical therapy failed, were randomized in a prospective study comparing RBL with BPEC. Treatment failure was predefined as continued bleeding, occurrence of a major complication, or failure to reduce the size of all internal hemorrhoidal segments to grade I in ≤ 3 treatments. Patients were followed up for 1 year. RESULTS: With similar patients, rectal bleeding and other symptoms were controlled with significantly fewer treatments of RBL than of BPEC (2.3±0.2 vs. 3.8±0.4, P < 0.05), and RBL had a significantly higher success rate (92% vs. 62%, P< 0.05). RBL had more cases of severe pain during treatment (8% vs. 0%, P> 0.05), but significantly fewer failures and crossovers (8% vs. 38%). Symptomatic recurrence at 1 year was 10% RBL and 15% BPEC. CONCLUSIONS: For patients with chronically bleeding grade II or III internal hemorrhoids that are unresponsive to medical therapy, safety and complication rates of banding and BPEC were similar. The success rate was significantly higher with RBL than with BPEC. Symptom recurrence rates at 1 year were similar. PMID:19513028

To describe our experience with total hepatectomy and liver transplantation as treatment for primary hepatoblastoma (HBL) and hepatocellular carcinoma (HCC) in children. A retrospective analysis of the perioperative course of 31 children with unresectable primary HBL (n = 12) and HCC (n = 19) who underwent transplantation between May 1989 and December 1998. Systemic (n = 18) and intraarterial (n = 7) neoadjuvant chemotherapy were administered; follow-up ranged from 1 to 185 months. For HBL, 1-year, 3-year, and 5-year posttransplantation survival rates were 92%, 92%, and 83%, respectively. Intravenous invasion, positive hilar lymph nodes, and contiguous spread did not have a significant adverse effect on outcome; distant metastasis was responsible for 2 deaths. Intraarterial chemotherapy was effective in all patients treated. For HCC, the overall 1-year, 3-year, and 5-year disease-free survival rates were 79%, 68%, and 63%, respectively. Vascular invasion, distant metastases, lymph node involvement, tumor size, and gender were significant risk factors for recurrence. Intraarterial chemotherapy was effective in 1 of 3 patients. Six patients died of recurrent HCC, and 3 deaths were unrelated to recurrent tumor. Liver transplantation for unresectable HBL and HCC can be curative. Risk factors for recurrence were significant only for HCC, with more advanced stages amenable to cure in the HBL group.

There have been significant advances in the management of complex colorectal polyps. Previous failed resection or polyp recurrence is associated with significant fibrosis, making endoscopic resection extremely challenging; the traditional approach to these lesions is surgery. The aim of this study was to evaluate the efficacy of a novel, knife-assisted snare resection (KAR) technique in the resection of scarred colonic polyps. This was a prospective cohort study of patients, in whom the KAR technique was used to resect scarred colonic polyps > 2  cm in size. Patients had previously undergone endoscopic mucosal resection (EMR) and developed recurrence, or EMR had been attempted but was aborted as a result of technical difficulty. A total of 42 patients underwent KAR of large (median 40  mm) scarred polyps. Surgery for benign disease was avoided in 38 of 41 patients (93 %). No life-threatening complications occurred. Recurrence was seen in six patients (16 %), five of whom underwent further endoscopic resection. The overall cure rate for KAR in complex scarred colonic polyps was 90 %. KAR of scarred colonic polyps by an expert endoscopist was an effective and safe technique with low recurrence rates. © Georg Thieme Verlag KG Stuttgart · New York.

Drug treatment rates with beta-blockers and ACE-inhibitors/angiotensin receptor blockers and recurrences in takotsubo cardiomyopathy: A meta-regression analysis.

In a recent paper Singh et al. analyzed the effect of drug treatment on recurrence of takotsubo cardiomyopathy (TTC) in a comprehensive meta-analysis. The study found that recurrence rates were independent of clinic utilization of BB prescription, but inversely correlated with ACEi/ARB prescription: authors therefore conclude that ACEi/ARB rather than BB may reduce risk of recurrence. We aimed to re-analyze data reported in the study, now weighted for populations' size, in a meta-regression analysis. After multiple meta-regression analysis, we found a significant regression between rates of prescription of ACEi and rates of recurrence of TTC; regression was not statistically significant for BBs. On the bases of our re-analysis, we confirm that rates of recurrence of TTC are lower in populations of patients with higher rates of treatment with ACEi/ARB. That could not necessarily imply that ACEi may prevent recurrence of TTC, but barely that, for example, rates of recurrence are lower in cohorts more compliant with therapy or more prescribed with ACEi because more carefully followed. Randomized prospective studies are surely warranted. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

The recurrence rate for stage I non-small cell lung cancer is high, with 20-40% of patients that relapse after surgery. The aim of this study was to evaluate new F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) derived parameters, such as standardized uptake value index (SUVindex), metabolic tumor volume (MTV) and total lesion glycolysis (TLG), as predictive factors for recurrence in resected stage I non-small cell lung cancer. We retrospectively reviewed 99 resected stage I non-small cell lung cancer patients that were grouped by SUVindex, TLG and MTV above or below their median value. Disease free survival was evaluated as primary end point. The 5-year overall survival and the 5-year disease free survival rates were 62% and 73%, respectively. The median SUVindex, MTL and TLG were 2.73, 2.95 and 9.61, respectively. Patients with low SUVindex, MTV and TLG were more likely to have smaller tumors (p ≤ 0.001). Univariate analysis demonstrated that SUVindex (p = 0.027), MTV (p = 0.014) and TLG (p = 0.006) were significantly related to recurrence showing a better predictive performance than SUVmax (p = 0.031). The 5-year disease free survival rates in patients with low and high SUVindex, MTV and TLG were 84% and 59%, 86% and 62% and 88% and 60%, respectively. The multivariate analysis showed that only TLG was an independent prognostic factor (p = 0.014) with a hazard ratio of 4.782. Of the three PET-derived parameters evaluated, TLG seems to be the most accurate in stratifying surgically treated stage I non-small cell lung cancer patients according to their risk of recurrence.

Several previous studies found that Asians transplanted for hepatitis B virus (HBV) infection had worse post-transplant outcomes than Caucasians. Data on post-transplant outcomes of African Americans and waitlist outcomes of Asian Americans and African Americans with hepatitis B are scant. The aim of this study was to compare waitlist and post-transplant outcomes among Asian Americans, African Americans, and Caucasians who had HBV-related liver disease. Data from a retrospective-prospective study on liver transplantation for HBV infection were analyzed. A total of 274 patients (116 Caucasians, 135 Asians, and 23 African Americans) from 15 centers in the United States were enrolled. African Americans were younger and more Asian Americans had hepatocellular carcinoma (HCC) at the time of liver transplant listing. The probability of undergoing transplantation and the probability of survival on the waitlist were comparable in the 3 racial groups. Of the 170 patients transplanted, 19 died during a median follow-up of 31 months. The probability of post-transplant survival at 5 years was 94% for African Americans, 85% for Asian Americans, and 89% for Caucasians (P = 0.93). HCC recurrence was the only predictor of post-transplant survival, and recurrence rates were similar in the 3 racial groups. Caucasians had a higher rate of HBV recurrence: 4-year recurrence was 19% versus 7% and 6% for Asian Americans and African Americans, respectively (P = 0.043). In conclusion, we found similar waitlist and post-transplant outcomes among Caucasians, Asian Americans, and African Americans with hepatitis B. Our finding of a higher rate of HBV recurrence among Caucasians needs to be validated in other studies. (c) 2009 AASLD.

To determine long-term oncological outcomes and complication rates for patients with clinically organ confined prostate adenocarcinoma (PCa) treated with open radical retropubic prostatectomy and pelvic lymph node dissection (RRP/PLND) in the prostate-specific antigen (PSA) era. Outcomes data were obtained from a prospectively maintained prostate cancer database. Patients with cT1/cT2 PCa undergoing RRP/PLND without neoadjuvant therapy between July 1988 and June 2008 were included. Kaplan-Meier and Cox proportional regression models were used to evaluate factors influencing biochemical recurrence, clinical recurrence, and overall survival (OS). A total of 2487 patients met inclusion criteria, and median follow-up was 7.2 years (range 1-21 years). Of the patients, 49.7% were low risk, 33.2% intermediate risk, and 16.1% high risk by D'Amico criteria, and 6% were LN+. The 10-year biochemical recurrence-free survival (BCRFS) for low-, intermediate-, and high-risk patients was 92%, 83%, and 76%, respectively (P < .001), and 10 year OS was 91%, 83%, and 74%, respectively (P < .001). BCRFS at 10 years was 76% and 88% for patients with positive and negative margins, respectively (P < .001). Of the 2487 patients, 11% developed BCR, and 3.7% experienced CR, with 9 local recurrences. The overall complication rate was 2.3%, and the cancer specific mortality rate was 2%. D'Amico risk group, margin status, and LN status are significantly correlated with outcomes in patients undergoing RRP/PLND for clinically localized PCa. Local recurrence and death from prostate cancer are rare in patients undergoing open RRP/PLND for clinically organ confined disease in the PSA era. Copyright © 2012 Elsevier Inc.

Background and purpose Accelerated partial breast irradiation (APBI) technology has theoretical advantages in comparison with traditional adjuvant radiation therapy (whole-breast irradiation; WBI) after breast-conserving surgery. However, published randomized controlled trials have shown inconsistent outcomes. Therefore, a comprehensive assessment of the effectiveness and safety of APBI technology is needed. Results A total of 7 studies of 7452 patients were included in this analysis. All 7 studies reported local recurrence as an outcome. Meta-analysis of 5 trials that included 6486 patients showed significantly different 5-year local recurrence rates for APBI and WBI groups (hazard ratio = 4.54, 95% confidence interval: 1.78–11.61, p = 0.002). Further analysis showed that this difference may be related to the choice of treatment methods. Benefit was conferred to the APBI group for the outcome of non-breast cancer deaths. There was no significant difference between the two groups in terms of nodal recurrence, systemic recurrence, overall survival, or mortality rates. Toxicity side effects and cosmetic effects were similar in both groups, but intraoperative radiotherapy seemed to have a greater acute response. Material and methods Searches for relevant randomized controlled trials of APBI versus WBI were performed using the following sources: PubMed, EMBASE, Cochrane Library, Web of Science. Two independent observers evaluated the identified studies. The meta-analysis was conducted using RevMan 5.2 software. Conclusions Although the analysis showed that patients receiving APBI had a higher local recurrence rate, subgroup analyses suggested that this might be related to treatment options. Patients who receive accurate radiotherapy may have greater benefits. APBI is a promising treatment technology and more phase III clinical trials are expected based on new treatments. PMID:28938661

Burr-hole irrigation and burr-hole drainage without irrigation are the most popular methods for treatment of chronic subdural haematoma. It is not well known if irrigation is necessary or which method has a higher recurrence rate. We compared the recurrence rates of those two methods. Forty-two patients were treated by burr-hole irrigation (irrigation group), whereas 38 patients were treated by burr-hole drainage (drainage group). Recurrence rate and its relation with sex, age, haematoma localization and aetiology were investigated in both groups. There was no significant difference between recurrence rates of the two groups. There was also no correlation between recurrence rate and age, sex, haematoma localization, or aetiology. There was no significant difference between recurrence rates of the two groups. Since the burr-hole drainage method is simpler to carry out, its use may be preferable.

AIM: To evaluated patterns and outcomes of hepatocellular carcinoma (HCC) recurrence after living donor liver transplantation (LDLT). METHODS: From 2001 to 2014, 293 patients underwent LDLT for HCC at our transplant center. We retrospectively reviewed 54 (18.4%) patients with HCC recurrence after LDLT. We evaluated patterns and outcomes of HCC recurrence after LDLT, with particular attention to the Milan criteria at transplantation, treatments for HCC-recurrent patients, and factors related to survival after HCC recurrence. Furthermore, we evaluated the efficacy of combination treatment of sorafenib and an mTOR inhibitor. RESULTS: The 1-, 2-, and 3-year overall survival rates after HCC recurrence were 41.1%, 20.5%, and 15.4%, respectively. The median time interval between LDLT and HCC recurrence was 6.5 mo. Although recurrence rates according to the Milan criteria at LDLT were significantly different, HCC recurrence patterns and survival rates after HCC recurrence were not significantly different between the two groups. Time to recurrence < 12 mo (P = 0.048), multiple recurrences at HCC recurrence (P = 0.038), and palliative treatment for recurrent tumors (P = 0.003) were significant independent prognostic factors for poor survival after HCC recurrence in a multivariate analysis. The combination treatment of sorafenib and sirolimus showed survival benefits in the palliative treatment group (P = 0.005). CONCLUSION: Curative treatment for recurrent HCC after LDLT is the most important factor in survival rates after HCC recurrence and combination treatments of sorafenib and an mTOR inhibitor could have survival benefits in patients with HCC recurrence after LT in the palliative treatment group.

This study retrospectively analyzed all patients with GBM who were treated with at least one cycle of BEV and FTM from July 2010 to October 2012. A total of 176 patients with recurrent GBM were enrolled. The response rate and disease control rate were 46.6% and 90.9%, respectively. A 6-month PFS rate of 33.3% (95% CI: 26.5%-40.3%) and a median PFS of 5.0 (95% CI: 2.4-7.5) months were observed. The median OS was 8.0 (95% CI: 6.7-9.2) months. Multivariate analysis showed that risk factors with a significant influence on the PFS of all patients were Karnofsky Performance Status (KPS) (≥70 versus <70, HR = 0.53, 95% CI: 0.39-0.73, and P = 0.01) and MGMT status (methylated versus unmethylated, HR = 0.69, 95% CI: 0.52-0.97, and P = 0.04). The most common treatment-related adverse events were fatigue, proteinuria, hypophonia, hypertension, thrombocytopenia, anemia, and neutropenia. In conclusion, combination of BEV with FTM is well tolerated and may derive some clinical benefits in recurrent GBM patients. Higher KPS and MGMT promoter hypermethylation were suggested to be associated with prolonged survival.

The management of rectal cancer has evolved significantly in the last few decades. Significant improvements in local disease control were achieved in the 1990s, with the introduction of total mesorectal excision and neoadjuvant radiotherapy. Level 1 evidence has shown that, with neoadjuvant chemoradiation therapy (CRT) the rates of local recurrence can be lower than 6% and, as a result, neoadjuvant CRT currently represents the accepted standard of care. This approach has led to reliable tumor down-staging, with 15–27% patients with a pathological complete response (pCR)—defined as no residual cancer found on histological examination of the specimen. Patients who achieve pCR after CRT have better long-term outcomes, less risk of developing local or distal recurrence and improved survival. For all these reasons, sphincter-preserving procedures or organ-preserving options have been suggested, such as local excision of residual tumor or the omission of surgery altogether. Although local recurrence rate has been stable at 5–6% with this multidisciplinary management method, distal recurrence rates for locally-advanced rectal cancers remain in excess of 25% and represent the main cause of death in these patients. For this reason, more recent trials have been looking at the administration of full-dose systemic chemotherapy in the neoadjuvant setting (in order to offer early treatment of disseminated micrometastases, thus improving control of systemic disease) and selective use of radiotherapy only in non-responders or for low rectal tumors smaller than 5 cm.

Omitting elective nodal irradiation (ENI) in limited-stage disease small cell lung cancer (LD-SCLC) is expected to result in smaller radiation fields. We report on data from a randomised phase II trial that omitted ENI in patients receiving concurrent chemo-radiotherapy for LD-SCLC. 38 patients with LD-SCLC were randomised to receive once-daily (66 Gy in 33 fractions) or twice-daily (45 Gy in 30 fractions) radiotherapy (RT). 3D-conformal RT was given concurrently with cisplatin and etoposide starting with the second cycle of a total of four cycles. The gross tumour volume was defined as primary tumour with involved lymph nodes (nodes ≥1 cm in short axis) identifiable with CT imaging. ENI was not used. Six recurrence patterns were identified: recurrence within planning target volume (PTV) only, recurrence within PTV+regional nodal recurrence and/or distant recurrence, isolated nodal recurrence outside PTV, nodal recurrence outside PTV+distant recurrence, distant metastases only and no recurrence. At median follow-up 16.9 months, 31/38 patients were evaluable and 14/31 patients had relapsed. There were no isolated nodal recurrences. Eight patients relapsed with intra-thoracic disease: 2 within PTV only, 4 within PTV and distantly and 2 with nodal recurrence outside PTV plus distant metastases. Rates of grade 3+ acute oesophagitis and pneumonitis in the 31 evaluable patients were 23 and 3% respectively. In our study of LD-SCLC, omitting ENI based on CT imaging was not associated with a high risk of isolated nodal recurrence, although further prospective studies are needed to confirm this. Routine ENI omission will be further evaluated prospectively in the ongoing phase III CONVERT trial (NCT00433563). Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

The optimal combination of available therapies for patients with resectable synchronous liver metastases from rectal cancer (SLMRC) is unknown, and the pattern of recurrence after resection has been poorly investigated. In this study, the authors examined recurrence patterns and survival after resection of SLMRC. Consecutive patients with SLMRC (disease-free interval, ≤12 months) who underwent complete resection of the rectal primary and liver metastases between 1990 and 2008 were identified from a prospective database. Demographics, tumor-related variables, and treatment-related variables were correlated with recurrence patterns. Competing risk analysis was used to determine the risk of pelvic and extrapelvic recurrence. In total, 185 patients underwent complete resection of rectal primary and liver metastases. One hundred eighty patients (97%) received chemotherapy during their treatment course, and 91 patients (49%) received pelvic radiation therapy either before (N = 65; 71.4%), or after (N = 26; 28.6%) rectal resection. The 5-year disease-specific survival rate was 51% for the entire cohort with a median follow-up of 44 months for survivors. One hundred thirty patients (70%) developed a recurrence: Eighteen patients (10%) had recurrences in the pelvis in combination with other sites, and 7 of these (4%) had an isolated pelvic recurrence. Recurrence pattern did not correlate with survival. Competing risk analysis demonstrated that the likelihood of a pelvic recurrence was significantly lower than that of an extrapelvic recurrence (P < .001). Of the patients with SLMRC who developed recurrent disease, systemic sites were overwhelmingly more common than pelvic recurrences. The current results indicated that the selective exclusion of radiotherapy may be considered in patients who are diagnosed with simultaneous disease. Copyright © 2012 American Cancer Society.

We evaluated the efficacy of imatinib mesylate in addition to hydroxyurea in patients with recurrent glioblastoma (GBM) who were either on or not on enzyme-inducing anti-epileptic drugs (EIAEDs). A total of 231 patients with GBM at first recurrence from 21 institutions in 10 countries were enrolled. All patients received 500 mg of hydroxyurea twice a day. Imatinib was administered at 600 mg per day for patients not on EIAEDs and at 500 mg twice a day if on EIAEDs. The primary end point was radiographic response rate and secondary end points were safety, progression-free survival at 6 months (PFS-6), and overall survival (OS). The radiographic response rate after centralised review was 3.4%. Progression-free survival at 6 months and median OS were 10.6% and 26.0 weeks, respectively. Outcome did not appear to differ based on EIAED status. The most common grade 3 or greater adverse events were fatigue (7%), neutropaenia (7%), and thrombocytopaenia (7%). Imatinib in addition to hydroxyurea was well tolerated among patients with recurrent GBM but did not show clinically meaningful anti-tumour activity.

The major problem in the treatment of rectal cancer is local recurrence. After the introduction of total mesorectal excision (TME), the recurrent rate decreased from 100% to around 10%. The purpose of the present study was to evaluate the quality of organ and tissue plane preservation in soft cadaver and to assess the feasibility to perform the procedure (mobilization of colon and rectum, total mesorectal excision and stapler anastomosis) in soft cadaver. Colorectal Division, Department of Surgery and Surgical Training Center Department of Anatomy, Faculty of Medicine, Chulalongkorn University. Prospective descriptive study. Seven soft cadavers were used for total mesorectal excision (TME) training. These procedures were performed by 21 participants (1 soft cadaver for 3 participants). The procedures were done under the supervision of experienced colorectal surgeons. The successfulness, satisfaction in performing the procedure and the quality of organ preservation were evaluated using standardized questionnaires. Participants were satisfied about TME training in soft cadaver (mean 8.24-8.71) and rated that soft cadavers were good in terms of internal organs and tissue plane preservation (mean 7.19-8.19) (0 = extremely unsatisfied, 10 = extremely satisfied). Training of TME in soft cadaver is feasible. The similarity in tissue quality (texture, consistency, color) of the preserved organs to that of the living and the good feel of performing the procedure make the trainee better understand the techniques and improve their skills.

Previous studies suggest that bridged mesh repair for abdominal wall reconstruction may result in worse outcomes than mesh-reinforced, primary fascial closure, particularly when acellular dermal matrix is used. We compared our outcomes of bridged versus reinforced repair using ADM in abdominal wall reconstruction procedures. This retrospective study included 535 consecutive patients at our cancer center who underwent abdominal wall reconstruction either for an incisional hernia or for abdominal wall defects left after excision of malignancies involving the abdominal wall with underlay mesh. A total of 484 (90%) patients underwent mesh-reinforced abdominal wall reconstruction and 51 (10%) underwent bridged repair abdominal wall reconstruction. Acellular dermal matrix was used, respectively, in 98% of bridged and 96% of reinforced repairs. We compared outcomes between these 2 groups using propensity score analysis for risk-adjustment in multivariate analysis and for 1-to-1 matching. Bridged repairs had a greater hernia recurrence rate (33.3% vs 6.2%, P < .001), a greater overall complication rate (59% vs 30%, P = .001), and worse freedom from hernia recurrence (log-rank P <.001) than reinforced repairs. Bridged repairs also had a greater rate of wound dehiscence (26% vs 14%, P = .034) and mesh exposure (10% vs 1%, P = .003) than mesh-reinforced abdominal wall reconstruction. When the treatment method was adjusted for propensity score in the propensity-score-matched pairs (n = 100), we found that the rates of hernia recurrence (32% vs 6%, P = .002), overall complications (32% vs 6%, P = .002), and freedom from hernia recurrence (68% vs 32%, P = .001) rates were worse after bridged repair. We did not observe differences in wound healing and mesh complications between the 2 groups. In our population of primarily cancer patients at MD Anderson Cancer Center bridged repair for abdominal wall reconstruction is associated with worse outcomes than mesh-reinforced abdominal wall reconstruction. Particularly when employing acellular dermal matrix, reinforced repairs should be used for abdominal wall reconstruction whenever possible. Copyright © 2016 Elsevier Inc. All rights reserved.

Laparoscopic surgery for colon cancer is associated with improved recovery and similar cancer outcomes at 3 and 5 years in comparison with open surgery. However, long-term survival rates have rarely been reported. Here, we present survival and recurrence rates of the Dutch patients included in the COlon cancer Laparoscopic or Open Resection (COLOR) trial at 10-year follow-up. Between March 1997 and March 2003, patients with non-metastatic colon cancer were recruited by 29 hospitals in eight countries and randomised to either laparoscopic or open surgery. Main inclusion criterion for the COLOR trial was solitary adenocarcinoma of the left or right colon. The primary outcome was disease-free survival at 3 years, and secondary outcomes included overall survival and recurrence. The 10-year follow-up data of all Dutch patients were collected. Analysis was by intention-to-treat. The trial was registered at ClinicalTrials.gov (NCT00387842). In total, 1248 patients were randomised, of which 329 were Dutch. Fifty-eight Dutch patients were excluded and 15 were lost to follow-up, leaving 256 patients for 10-year analysis. Median follow-up was 112 months. Disease-free survival rates were 45.2 % in the laparoscopic group and 43.2 % in the open group (difference 2.0 %; 95 % confidence interval (CI) -10.3 to 14.3; p = 0.96). Overall survival rates were 48.4 and 46.7 %, respectively (difference 1.7 %; 95 % CI -10.6 to 14.0; p = 0.83). Stage-specific analysis revealed similar survival rates for both groups. Sixty-two patients were diagnosed with recurrent disease, accounting for 29.4 % in the laparoscopic group and 28.2 % in the open group (difference 1.2 %; 95 % CI -11.1 to 13.5; p = 0.73). Seven patients had port- or wound-site recurrences (laparoscopic n = 3 vs. open n = 4). Laparoscopic surgery for non-metastatic colon cancer is associated with similar rates of disease-free survival, overall survival and recurrences as open surgery at 10-year follow-up.

Laboratory constraints on models of earthquake recurrence

In this study, rock friction "stick-slip" experiments are used to develop constraints on models of earthquake recurrence. Constant rate loading of bare rock surfaces in high-quality experiments produces stick-slip recurrence that is periodic at least to second order. When the loading rate is varied, recurrence is approximately inversely proportional to loading rate. These laboratory events initiate due to a slip-rate-dependent process that also determines the size of the stress drop and, as a consequence, stress drop varies weakly but systematically with loading rate. This is especially evident in experiments where the loading rate is changed by orders of magnitude, as is thought to be the loading condition of naturally occurring, small repeating earthquakes driven by afterslip, or low-frequency earthquakes loaded by episodic slip. The experimentally observed stress drops are well described by a logarithmic dependence on recurrence interval that can be cast as a nonlinear slip predictable model. The fault's rate dependence of strength is the key physical parameter. Additionally, even at constant loading rate the most reproducible laboratory recurrence is not exactly periodic, unlike existing friction recurrence models. We present example laboratory catalogs that document the variance and show that in large catalogs, even at constant loading rate, stress drop and recurrence covary systematically. The origin of this covariance is largely consistent with variability of the dependence of fault strength on slip rate. Laboratory catalogs show aspects of both slip and time predictability, and successive stress drops are strongly correlated indicating a "memory" of prior slip history that extends over at least one recurrence cycle.

Recurrent ankle sprains can be reduced by following a neuromuscular training (NMT) program via a printed Booklet or a mobile application. Regarding the high incidence of ankle sprains, cost-effectiveness regarding implementation can have a large effect on total societal costs. In this economic analysis, we evaluated whether the method of implementing a proven effective NMT program using an App or a Booklet resulted in differences in injury incidence rates leading to costs and hence to differences in cost-effectiveness. In total, 220 athletes with a previous ankle sprain were recruited for this randomized controlled trial with a follow-up of 12 months. Half of the athletes used the freely available "Strengthen your ankle" App and the other half received a printed Booklet. After the 8-week program, athletes were questioned monthly on their recurrent injuries. Primary outcome measures were incidence density of ankle injury and incremental cost-effectiveness ratio (ICER). During follow-up, 31 athletes suffered from a recurrent ankle sprain that led to costs resulting in a hazard ratio of 1.13 (95% CI: 0.56-2.27). The incremental cost-effectiveness ratio of the App group in comparison with the Booklet group was €361.52. The CE plane shows that there was neither a difference in effects nor in costs between both intervention methods. This study showed that the method of implementing the NMT program using an App or a Booklet led to similar cost-effectiveness ratios and the same occurrence of recurrent injuries leading to costs. Both the App and the Booklet can be used to prevent recurrent ankle injuries, showing no differences in (cost-) effectiveness at 12-month follow-up. © 2017 John Wiley & Sons A/S.

Radiofrequency current energy (RFC) ablation is still considered as the gold standard for atrioventricular nodal reentrant tachycardia (AVNRT). Success-rates for AVNRT ablation vary irrespective of the ablation technology and strategy. This study aimed to access safety, efficacy, and long-term outcome of RFC catheter ablation for the treatment of AVNRT in children and adolescents aged < 19 years with special focus on modulation versus ablation of the AV nodal slow pathway (SP). A total number of 1143 patients (pts) < 19 years were referred for invasive electrophysiological testing due to paroxysmal supraventricular tachycardia (SVT). Diagnosis of AVNRT was confirmed in 412 pts, and RFC-guided ablation was attempted in 386 pts (age 13.0 ± 3.5 years). No permanent complications were observed. RFC application resulted in SP-ablation in 171/386 (44.3%) and in SP modulation in 208/386 (53.9%) children, whereas attempts for RFC treatment failed in 7 pts. Follow-up was completed for 396/412 patients (96.1%). Within a mean follow-up period of 54.9 ± 39.7 months, in 51/379 pts (13.5%) AVNRT recurrence was observed. The median time until tachycardia recurrence was 19.5 months. No difference for AVNRT recurrence was found comparing SP ablation versus SP modulation (p > 0.05), whereas the recurrence rate was significantly higher in patients with non-inducible SVT and therefore empiric SP treatment as compared to patients with inducible AVNRT (p = 0.01). RFC-guided ablation for AVNRT in children and adolescents is safe and leads to an acceptable long-term freedom from recurrences. SP modulation and SP ablation resulted in comparable acute and long-term success rates. Late AVNRT recurrences can occur even after years of freedom from tachycardia-related symptoms.

Chinese herbal medicine for the treatment of recurrent miscarriage: a systematic review of randomized clinical trials

PubMed Central

2013-01-01

Background Traditional Chinese medicine has been widely used for the treatment of recurrent miscarriage in China and other Asian countries for long time. We conducted this review to systematically summarize the evidences of Chinese herbal medicine (CHM) for the prevention and treatment of recurrent miscarriage in randomized trials, and evaluate the effectiveness and safety of CHM compared with placebo or conventional medicine. Methods We searched studies in PubMed, ClinicalTrials, the Cochrane Library, CNKI, SinoMed and VIP databases until December, 2012. Randomized trials on CHM alone or in combination with conventional medicine for recurrent miscarriage compared with placebo or conventional medicine were included. We evaluated the methodological quality of each included trials using the Cochrane risk of bias tool. Results A total of 41 RCTs (3660 participants) were included. The majority of trials had a high or unclear risk of bias. CHM used alone or plus progesterone-based treatment showed superior effect over progesterone-based treatment in improving live birth rate and embryonic developmental state (measured by B ultrasound). However, there is substantial heterogeneity within each subgroup analysis (I2 ranging from 35% to 71%). CHM plus progesterone and hCG-based treatment was superior to progesterone and hCG-based treatment in improving the embryonic developmental state, but not live birth rate. No severe adverse events were reported in relation to CHM. Conclusions Some Chinese herbal medicines or in combination with progesterone-based treatment demonstrated potentially beneficial effect in improving live birth rate and embryonic developmental state for women with recurrent miscarriage. However, due to the substantial heterogeneity among the herbal interventions and limitations of methodological quality of the included trials, it is not possible to recommend any specific CHMs for recurrent miscarriage. Further rigorous clinical trials are warranted to evaluate the efficacy and safety of CHM. PMID:24245671

Enchondromas represent the most common primary bone tumor in the hand. Despite their frequency, a standardized treatment protocol is lacking. This study examines the outcome of surgically treated enchondromas of the hand with regard to tumor location, graft choice, and presence or absence of fracture. We retrospectively reviewed 102 enchondromas in 80 patients, identified between 1991 and 2008, with a mean clinical follow-up of 38 months. We assessed the effects of age, tumor location, and graft choice on outcomes for all lesions. Patients presenting with Ollier disease, Maffucci syndrome, pathologic fractures, or recurrent disease were separated for additional analysis. Of the 102 lesions, 62 (61%) achieved complete radiographic healing in a median time of 6 months. Full range of motion was achieved following treatment of 68 lesions (67%) in a median time of 3 months. A total of 95 lesions (93%) remained recurrence free following surgery. One case of malignant transformation occurred in a patient with Maffucci syndrome. Tumor location and graft choice did not affect healing grade, time to healing, range of motion, or recurrence rate. Age at presentation greater than 30 was associated with more rapid healing. Monocentric, nonexpanding lesions were associated with improved postoperative range of motion. Patients with a diagnosis of multiple enchondromas had a higher rate of recurrence following surgery, and patients presenting with a recurrent lesion had a higher rate of complications. Following pathologic fracture, no differences in outcomes were observed when enchondromas were treated primarily or following fracture healing. Following surgical treatment of enchondromas in the hand, the majority of patients achieve complete bony healing and full range of motion, regardless of the graft material used. Malignant transformation is rare, and aggressive follow-up measures should be reserved for patients with a diagnosis of multiple enchondromas. Therapeutic IV.

Two revolutions in inguinal hernia repair surgery have occurred during the last two decades. The first was the introduction of tension-free hernia repair by Liechtenstein in 1989 and the second was the application of laparoscopic surgery to the treatment of inguinal hernia in the early 1990s. The purposes of this study were to assess the safety and effectiveness of laparoscopic totally extraperitoneal (TEP) repair and to discuss the technical changes that we faced on the basis of our accumulative experience. Patients who underwent an elective inguinal hernia repair at the Department of Abdominal Surgery at the Institute of Laparoscopic Surgery (ILS), Bordeaux, between June 1990 and May 2005 were enrolled retrospectively in this study. Patient demographic data, operative and postoperative course, and outpatient follow-up were studied. A total of 3,100 hernia repairs were included in the study. The majority of the hernias were repaired by TEP technique; the repair was done by transabdominal preperitoneal (TAPP) repair in only 3%. Eleven percent of the hernias were recurrences after conventional repair. Mean operative time was 17 min in unilateral hernia and 24 min in bilateral hernia. There were 36 hernias (1.2%) that required conversion: 12 hernias were converted to open anterior Liechtenstein and 24 to laparoscopic TAPP technique. The incidence of intraoperative complications was low. Most of the patients were discharged at the second day of the surgery. The overall postoperative morbidity rate was 2.2%. The incidence of recurrence rate was 0.35%. The recurrence rate for the first 200 repairs was 2.5%, but it decreased to 0.47% for the subsequent 1,254 hernia repairs According to our experience, in the hands of experienced laparoscopic surgeons, laparoscopic hernia repair seems to be the favored approach for most types of inguinal hernias. TEP is preferred over TAPP as the peritoneum is not violated and there are fewer intra-abdominal complications.

Whether whole-body MRI can predict occurrence of recurrent events in patients with diabetes mellitus. Whole-body MRI was prospectively applied to 61 diabetics and assessed for arteriosclerosis and ischemic cerebral/myocardial changes. Occurrence of cardiocerebral events and diabetic comorbidites was determined. Patients were stratified whether no, a single or recurrent events arose. As a secondary endpoint, events were stratified into organ system-specific groups. During a median follow-up of 70 months, 26 diabetics developed a total of 39 events; 18 (30%) developed one, 8 (13%) recurrent events. Between diabetics with no, a single and recurrent events, a stepwise higher burden was observed for presence of left ventricular (LV) hypo-/akinesia (3/28/75%, p < 0.0001), myocardial delayed-contrast-enhancement (17/33/63%, p = 0.001), carotid artery stenosis (11/17/63%, p = 0.005), peripheral artery stenosis (26/56/88%, p = 0.0006) and vessel score (1.00/1.30/1.76, p < 0.0001). After adjusting for clinical characteristics, LV hypo-/akinesia (hazard rate ratio = 6.57, p < 0.0001) and vessel score (hazard rate ratio = 12.29, p < 0.0001) remained independently associated. Assessing organ system risk, cardiac and cerebral MR findings predicted more strongly events in their respective organ system. Vessel-score predicted both cardiac and cerebral, but not non-cardiocerebral, events. Whole-body MR findings predict occurrence of recurrent events in diabetics independent of clinical characteristics, and may concurrently provide organ system-specific risk. • Patients with long-standing diabetes mellitus are at high risk for recurrent events. • Whole-body MRI predicts occurrence of recurrent events independently of clinical characteristics. • The vessel score derived from whole-body angiography is a good general risk-marker. • Whole-body MRI may also provide organ-specific risk assessment. • Current findings may indicate benefits of whole-body MRI for risk stratification.

To investigate the efficacy of adenosine triphosphate (ATP)-tumor chemosensitivity assay (TCA) directed chemotherapy in patients with recurrent epithelial ovarian cancer. From August 2010 to June 2012, recurrent epithelial ovarian cancer patients were prospectively enrollmented in Cancer Hospital, Peking Union Medical College,Chinese Academy of Medical Sciences.The entry criteria are as follows: (1) Histologically proven to be epithelial ovarian cancer. (2) Patients of recurrent ovarian cancer with bidimensionally measurable tumor, or ascitic or pleural fluid for testing. (3) Karnofsky performance status > 60. (4) A life expectancy of at least more than 6 months.According to patients desires, they were assigned into two groups: assay-directed therapy group and physician's-choice therapy group, patients' clinical and pathological characteristics, response rate to chemotherapy and progression-free survival (PFS) were compared between two groups. A total of 113 patients with recurrent epithelial ovarian cancer were prospectively enrollmented to assay-directed chemotherapy (n = 56) or physician's-choice chemotherapy (n = 57).There was no difference in median age,types of recurrence, surgical-pathological stage, pathological type, tumor grade, times of recurrence, residual disease at secondary cytoreductive surgery between assay-directed group and physician's-choice group. The overall response rate (ORR) and median PFS in the ATP-TCA group was 66% (37/56) and 7 months, while the ORR in the control group was 46% (26/57, P = 0.037), the median PFS was 4 months (P = 0.040). For platinum-resistant patients, the ORR between ATP-TCA directed chemotherapy 59% (16/27) and control group 25% (7/28) were significantly different (P = 0.010), and the median PFS between two groups were also significantly different (5 months and 2 months, respectively, P = 0.003). ATP-TCA directed chemotherapy could improve ORR and PFS in patients with recurrent epithelial ovarian cancer, especially in platinum-resistant patients.

Women with gestational diabetes mellitus (GDM) may be able to reduce their risk of recurrent GDM and progression to type 2 diabetes mellitus through lifestyle change; however, there is limited population-based information on GDM recurrence rates. We used data from a population of women delivering two sequential live singleton infants in Massachusetts (1998-2007) to estimate the prevalence of chronic diabetes mellitus (CDM) and GDM in parity one pregnancies and recurrence of GDM and progression from GDM to CDM in parity two pregnancies. We examined four diabetes classification approaches; birth certificate (BC) data alone, hospital discharge (HD) data alone, both sources hierarchically combined with a diagnosis of CDM from either source taking priority over a diagnosis of GDM, and both sources combined including only pregnancies with full agreement in diagnosis. Descriptive statistics were used to describe population characteristics, prevalence of CDM and GDM, and recurrence of diabetes in successive pregnancies. Diabetes classification agreement was assessed using the Kappa statistic. Associated maternal characteristics were examined through adjusted model-based t tests and Chi square tests. A total of 134,670 women with two sequential deliveries of parities one and two were identified. While there was only slight agreement on GDM classification across HD and BC records, estimates of GDM recurrence were fairly consistent; nearly half of women with GDM in their parity one pregnancy developed GDM in their subsequent pregnancy. While estimates of progression from GDM to CDM across sequential pregnancies were more variable, all approaches yielded estimates of ≤5 %. The development of either GDM or CDM following a parity one pregnancy with no diagnosis of diabetes was <3 % across approaches. Women with recurrent GDM were disproportionately older and foreign born. Recurrent GDM is a serious life course public health issue; the inter-pregnancy interval provides an important window for diabetes prevention.

INTRODUCTION: The repair of the recurrent hernia is a daunting task because of already weakened tissues and distorted anatomy. Open posterior preperitoneal approach gives results far superior to those of the anterior approach. Laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair is an evolving technique associated with advantages of a minimally invasive approach. The present work aimed at comparing these three approaches for repair of recurrent inguinal hernia regarding complications and early recurrence. MATERIALS AND METHODS: A total of 180 patients were divided randomly into three equal groups: A, B, and C. Group A patients were subjected to open posterior preperitoneal approach , those of group B were subjected to transinguinal anterior tension-free repair and group C patients were subjected to TAPP. The primary end point was recurrence and the secondary end points were time off from work, postoperative pain, scrotal swelling, and wound infections. RESULTS: The mean hospital stay, the mean time to return to work and the mean time off from work were less in group C then A and B. Chronic postoperative pain was observed in eight patients in group A (13.33%), in 18 patients in group B (30%) and six patients in group C (10%). The overall complication rate was 19.7% in both groups A and C and 34.36% in group B. CONCLUSION: In recurrent inguinal hernia, the laparoscopic and open posterior approaches are equally effective in term of operative outcome. The open preperitoneal hernia repair is inexpensive, has a low recurrence rate. Postoperative recovery is short and postoperative pain is minimal. This approach gives results far superior to those of the commonly used anterior approach. However, while laparoscopic hernia repair requires a lengthy learning curve and is difficult to learn and perform, it has advantages of less post-operative pain, early recovery with minimal hospital stay, low post-operative complications and recurrence.

High-Dose Chemotherapy and Autologous Stem Cell Transplantation in Children with High-Risk or Recurrent Bone and Soft Tissue Sarcomas

PubMed Central

2016-01-01

Despite increasing evidence that high-dose chemotherapy and autologous stem cell transplantation (HDCT/auto-SCT) might improve the survival of patients with high-risk or recurrent solid tumors, therapy effectiveness for bone and soft tissue sarcoma treatment remains unclear. This study retrospectively investigated the feasibility and effectiveness of HDCT/auto-SCT for high-risk or recurrent bone and soft tissue sarcoma. A total of 28 patients (18 high-risk and 10 recurrent) underwent single or tandem HDCT/auto-SCT between October 2004 and September 2014. During follow-up of a median 15.3 months, 18 patients exhibited disease progression and 2 died of treatment-related toxicities (1 veno-occlusive disease and 1 sepsis). Overall, 8 patients remained alive and progression-free. The 3-year overall survival (OS) and event-free survival (EFS) rates for all 28 patients were 28.7% and 26.3%, respectively. In the subgroup analysis, OS and EFS rates were higher in patients with complete or partial remission prior to HDCT/auto-SCT than in those with worse responses (OS, 39.1% vs. 0.0%, P = 0.002; EFS, 36.8% vs. 0.0%, P < 0.001). Therefore, careful selection of patients who can benefit from HDCT/auto-SCT and maximal effort to reduce tumor burden prior to treatment will be important to achieve favorable outcomes in patients with high-risk or recurrent bone and soft tissue sarcomas.

This systematic review and meta-analysis aimed to evaluate the overall survival, local recurrence, distant metastasis, and complications of mediastinal lymph node dissection (MLND) versus mediastinal lymph node sampling (MLNS) in stage I-IIIA non-small cell lung cancer (NSCLC) patients. A systematic search of published literature was conducted using the main databases (MEDLINE, PubMed, EMBASE, and Cochrane databases) to identify relevant randomized controlled trials that compared MLND vs. MLNS in NSCLC patients. Methodological quality of included randomized controlled trials was assessed according to the criteria from the Cochrane Handbook for Systematic Review of Interventions (Version 5.1.0). Meta-analysis was performed using The Cochrane Collaboration's Review Manager 5.3. The results of the meta-analysis were expressed as hazard ratio (HR) or risk ratio (RR), with their corresponding 95% confidence interval (CI). We included results reported from six randomized controlled trials, with a total of 1,791 patients included in the primary meta-analysis. Compared to MLNS in NSCLC patients, there was no statistically significant difference in MLND on overall survival (HR = 0.77, 95% CI 0.55 to 1.08; P = 0.13). In addition, the results indicated that local recurrence rate (RR = 0.93, 95% CI 0.68 to 1.28; P = 0.67), distant metastasis rate (RR = 0.88, 95% CI 0.74 to 1.04; P = 0.15), and total complications rate (RR = 1.10, 95% CI 0.67 to 1.79; P = 0.72) were similar, no significant difference found between the two groups. Results for overall survival, local recurrence rate, and distant metastasis rate were similar between MLND and MLNS in early stage NSCLC patients. There was no evidence that MLND increased complications compared with MLNS. Whether or not MLND is superior to MLNS for stage II-IIIA remains to be determined.

Shoulder instability is a topic of significant interest within the sports medicine literature, particularly regarding recurrence rates and the ideal treatment indications and techniques. Little has been published specifically addressing the occupational implications of symptomatic recurrent shoulder instability. Previous arthroscopic repair will continue to be a significant predisposing factor for recurrent instability in a young, active population, and that recurrent instability may have a negative effect on college graduation and postgraduate occupational selection. Case series. Level 4. We conducted a retrospective review of approved medical waivers for surgical treatment of anterior shoulder dislocation or instability prior to matriculation at the US Military Academy or the US Naval Academy for the graduating classes of 2010 to 2013. Statistical analysis was performed to determine the incidence and risk factors for recurrence and to determine the impact on graduation rate and occupation selection. Fifty-nine patients were evaluated; 34% developed recurrent anterior instability. Patients with previous arthroscopic repair had a significantly higher incidence of recurrence (38%, P = 0.044). Recurrent shoulder instability did not significantly affect graduation rates or self-selected occupation ( P ≥ 0.05). There is a significant rate of recurrent shoulder instability after primary surgical repair, particularly among young, active individuals. In addition, arthroscopic repair resulted in a significantly higher recurrence rate compared with open repair in our population. Surgical repair for shoulder instability should not necessarily preclude young individuals from pursuing (or being considered for) occupations that may place them at greater risk of recurrence. The risk of recurrent instability is greater than the rate typically described, which may suggest that some subpopulations are at greater risk than others. A unique data point regarding instability is the effect on occupation selection.

Liquid nitrogen spray cryotherapy (LNSCT) has been shown to be a safe, well-tolerated, and effective therapy for Barrett's esophagus (BE)-associated high-grade dysplasia (BE-HGD) and intramucosal adenocarcinoma (IMC). Long-term follow-up is lacking. The aim of this study was to assess the efficacy, durability, and rate of neoplastic progression after LNSCT in BE-HGD/IMC at 3 and 5 years. In this single-center, retrospective study drawn from a prospective database, patients with BE-HGD/IMC of any length treated with LNSCT were followed with surveillance endoscopy with biopsy for 3 to 5 years. Patients with IMC completely removed by endoscopic resection were included. Outcome measures included complete eradication of HGD (CE-HGD), dysplasia, and intestinal metaplasia; incidence rates; durability of response; location of recurrent intestinal metaplasia and dysplasia; and rate of disease progression. A total of 50 and 40 patients were included in 3-year and 5-year analyses. Initial CE-HGD, dysplasia, and intestinal metaplasia achieved in 98%, 90%, and 60%, respectively. Overall CE-HGD, dysplasia, and intestinal metaplasia at 3 years were 96% (48/50), 94% (47/50), and 82% (41/50), and at 5 years were 93% (37/40), 88% (35/40), and 75% (30/40). Incidence rates of recurrent intestinal metaplasia, dysplasia, and HGD/esophageal adenocarcinoma per person-year of follow-up after initial complete eradication of intestinal metaplasia (CE-IM) were 12.2%, 4.0%, and 1.4% per person-year for the 5-year cohort. Most recurrences were found immediately below the neosquamocolumnar junction. Two of 7 HGD recurrences occurred later than 4 years after initial eradication, and 2 patients (4%) progressed to adenocarcinoma despite treatment. In patients with BE-HGD/IMC, LNSCT is effective in eliminating dysplasia and intestinal metaplasia. Progression to adenocarcinoma was uncommon, and recurrence of dysplasia was successfully treated in most cases. Long-term surveillance is necessary to detect late recurrence of dysplasia.

A retrospective analysis was performed on 267 consecutive patients with Graves' disease (GD). The principal aim of this study was to evaluate the risk for recurrence and complications when changing the surgical method from subtotal (ST) to total thyroidectomy (TT). Information from 267 consecutive patients operated on for GD between 2000 and 2006 was collected at Uppsala University Hospital (143) and Falun County Hospital (128). There were 229 women and 38 men. Four patients were operated on twice. A total of 40 STs and 229 TTs were performed. Results were compared to those of a previous cohort from the same hospital, with a majority of STs (157/176) performed from 1980 to 1992. The risk for relapse of GD was reduced from 20 to 3.3 % after the shift from ST to TT. In terms of surgical complications, 2.2 % demonstrated permanent vocal cord paralysis and 4.5 % had persistent hypocalcemia, not significant when compared to the previous cohort. In spite of TT, there were four recurrences, all due to remnant thyroid tissue high up at the hyoid bone. Changing the surgical method did not affect postoperative progression of dysthyroid ophthalmopathy (DO, 7.0 vs. 7.5 %). There were no differences in outcome with respect to which hospital the patients had their operation. Change from ST to TT dramatically reduced the risk for recurrence of GD without increasing the rate of complications. TT is not more effective than ST in hampering progression of DO as has been advocated by some. Careful surgical dissection up to the hyoid bone is necessary to avoid recurrence.

Intraoperative Radiation Therapy Reduces Local Recurrence Rates in Patients With Microscopically Involved Circumferential Resection Margins After Resection of Locally Advanced Rectal Cancer

Purpose: Intraoperative radiation therapy (IORT) is advocated by some for patients with locally advanced rectal cancer (LARC) who have involved or narrow circumferential resection margins (CRM) after rectal surgery. This study evaluates the potentially beneficial effect of IORT on local control. Methods and Materials: All surgically treated patients with LARC treated in a tertiary referral center between 1996 and 2012 were analyzed retrospectively. The outcome in patients treated with IORT with a clear but narrow CRM (≤2 mm) or a microscopically involved CRM was compared with the outcome in patients who were not treated with IORT. Results: A total of 409 patients underwent resectionmore » of LARC, and 95 patients (23%) had a CRM ≤ 2 mm. Four patients were excluded from further analysis because of a macroscopically involved resection margin. In 43 patients with clear but narrow CRMs, there was no difference in the cumulative 5-year local recurrence-free survival of patients treated with (n=21) or without (n=22) IORT (70% vs 79%, P=.63). In 48 patients with a microscopically involved CRM, there was a significant difference in the cumulative 5-year local recurrence-free survival in favor of the patients treated with IORT (n=31) compared with patients treated without IORT (n=17) (84 vs 41%, P=.01). Multivariable analysis confirmed that IORT was independently associated with a decreased local recurrence rate (hazard ratio 0.24, 95% confidence interval 0.07-0.86). There was no significant difference in complication rate of patients treated with or without IORT (65% vs 52%, P=.18) Conclusion: The current study suggests that IORT reduces local recurrence rates in patients with LARC with a microscopically involved CRM.« less

The aim of the article is to answer the question if the Taiwan unemployment rate dynamics is generated by a non-linear deterministic dynamic process. This paper applies a recurrence plot and recurrence quantification approach based on the analysis of non-stationary hidden transition patterns of the unemployment rate of Taiwan. The case study uses the time series data of the Taiwan’s unemployment rate during the period from 1978/01 to 2010/06. The results show that recurrence techniques are able to identify various phases in the evolution of unemployment transition in Taiwan.

There is continuing debate on the optimal treatment for Grave's thyrotoxicosis with a resultant variation in clinical practice. The present study aimed to ascertain changes in practice in the treatment of Grave's thyrotoxicosis in Tayside, Scotland, over the past four decades. Methods. The "Scottish automated follow-up register" (SAFUR) was queried to identify all patients treated for Grave's thyrotoxicosis from 1968 to 2007 inclusive. Patients were divided into 4 groups (Groups A to D) according to the decades. Demographic profile, treatment modalities, radioactive iodine (RAI) dose, and recurrence rates were studied and outcomes were compared by χ (2) test and ANOVA using SPSS v15.0. A p value of < 0.05 was considered significant. Results. Altogether, 3737 patients were diagnosed with Grave's thyrotoxicosis over the 4 decades. Use of RAI has increased from 43.1% in Group A to 68% in Group D (p < 0.001). The dose of RAI has increased (p < 0.001) and there has been a reduction in recurrence rate with higher dose of RAI. Surgical intervention rates decreased from 55.3% to 12.3% (p < 0.001) over time. Conclusions. Analysis of a large dataset of patients with Grave's thyrotoxicosis suggests increasing use of RAI as the preferred first line of treatment. Furthermore, using a single higher dose of RAI and adoption of total thyroidectomy have decreased recurrence rates.

Axillary osmidrosis can lead to personal and social problems, particularly in Asian culture. Superficial liposuction with curettage and subcutaneous laser are surgical intervention commonly used for osmidrosis. Retrospectively, we compared the effectiveness and complications between superficial liposuction with curettage and subcutaneous laser in an Asian population. Totally, 66 and 19 patients receiving subcutaneous laser and superficial liposuction with curettage (LC) were recruited. The effectiveness of treatment was assessed by patients subjectively. Recurrence rate of osmidrosis and complications were also evaluated. 95% of patients showed good-to-excellent improvement in LC group and only 30% of patients showing good-to-excellent results in laser group (P < 0.01). Binary logistic regression revealed that the odds ratio of LC was 53.288 (P = 0.006) for >50% improvement in osmidrosis. The recurrence rate was not significantly different (P = 0.139), however, the duration to recurrence of osmidrosis was significantly longer in LC group (P < 0.01). The complication rate was 31% in LC group and 6% in laser group (P < 0.01). Superficial liposuction with curettage provides more effective treatment with higher complication rates and is possibly suitable for severe patients. For mild-to-moderate osmidrosis, or preferring a better cosmetic result or short recovery, subcutaneous laser could be applied. © 2015 European Academy of Dermatology and Venereology.

Current management of basal cell carcinoma is surgical excision. Most resections use predetermined surgical margins. The basis of ideal resection margins is almost completely from retrospective data and mainly from small case series. This article presents a systematic analysis from a large pool of data to provide a better basis of determining ideal surgical margin. A systematic analysis was performed on data from 89 articles from a larger group of 973 articles selected from the PubMed database. Relevant inclusion and exclusion criteria were applied to all articles reviewed and the data were entered into a database for statistical analysis. The total number of lesions analyzed was 16,066; size ranged from 3 to 30 mm (mean, 11.7 ± 5.9 mm). Surgical margins ranged from 1 to 10 mm (mean, 3.9 ± 1.4 mm). Negative surgical margins ranged 45 to 100 percent (mean, 86 ± 12 percent). Recurrence rates for 5-, 4-, 3-, and 2-mm surgical margins were 0.39, 1.62, 2.56, and 3.96 percent, respectively. Pooled data for incompletely excised margins have an average recurrence rate of 27 percent. A 3-mm surgical margin can be safely used for nonmorpheaform basal cell carcinoma to attain 95 percent cure rates for lesions 2 cm or smaller. A positive pathologic margin has an average recurrence rate of 27 percent.

Vertigo and dizziness are among the most prevalent symptoms in neurologic disorders. Although many of these patients suffer from postural instability and gait disturbances, there is only limited data on their risk of falling. We conducted a controlled cross-sectional study at the tertiary care outpatient clinic of the German Center for Vertigo and Balance Disorders using a self-administered questionnaire to assess falls, fall-related injuries, and fear of falling. The recruitment period was 6 months. A total of 569 patients (mean age 59.6 ± 17.1 years, 55% females) and 100 healthy participants were included (response rate > 90%). Dizzy patients with central balance disorders (Parkinsonian, cerebellar, and brainstem oculomotor syndromes) had the highest fall rates (> 50% recurrent fallers, odds ratio > 10). The rate of recurrent fallers was 30% in bilateral vestibular failure and peripheral neuropathy (odds ratio > 5). Patients with functional dizziness (somatoform or phobic vertigo) were concerned about falling but did not fall more often than healthy controls (odds ratio 0.87). Falls are common in patients presenting to a dizziness unit. Those with central syndromes are at risk of recurrent and injurious falling. Fall rates and fear of falling should be assessed in balance disorders and used to guide the regimen of rehabilitation therapy. The identification of risk factors would help provide protective measures to these groups of patients.

Hepatobiliary magnetic resonance imaging (MRI) provides additional information beyond the size and number of tumours, and may have prognostic implications. We examined whether pretransplant radiological features on MRI could be used to stratify the risk of tumour recurrence after liver transplantation (LT) for hepatocellular carcinoma (HCC). A total of 100 patients who had received a liver transplant and who had undergone preoperative gadoxetic acid-enhanced MRI, including the hepatobiliary phase (HBP), were reviewed for tumour size, number, and morphological type (e.g. nodular, nodular with perinodular extension, or confluent multinodular), satellite nodules, non-smooth tumour margins, peritumoural enhancement in arterial phase, peritumoural hypointensity on HBP, and apparent diffusion coefficients. The primary endpoint was time to recurrence. In a multivariable adjusted model, the presence of satellite nodules [hazard ratio (HR) 3.07; 95% confidence interval (CI) 1.14-8.24] and peritumoural hypointensity on HBP (HR 4.53; 95% CI 1.52-13.4) were identified as independent factors associated with tumour recurrence. Having either of these radiological findings was associated with a higher tumour recurrence rate (72.5% vs. 15.4% at three years, p <0.001). When patients were stratified according to the Milan criteria, the presence of these two high-risk radiological findings was associated with a higher tumour recurrence rate in both patients transplanted within the Milan criteria (66.7% vs. 11.6% at three years, p <0.001, n = 68) and those who were transplanted outside the Milan criteria (75.5% vs. 28.6% at three years, p <0.001, n = 32). Radiological features on preoperative hepatobiliary MRI can stratify the risk of tumour recurrence in patients who were transplanted either within or outside the Milan criteria. Therefore, hepatobiliary MRI can be a useful way to select potential candidates for LT. High-risk radiological findings on preoperative hepatobiliary magnetic resonance imaging (either one of the following features: satellite nodule and peritumoural hypointensity on hepatobiliary phase) were associated with a higher tumour recurrence rate in patients transplanted either within or outside the Milan criteria.

Current guidelines derived from a pre-human papilloma virus (HPV) era in oropharyngeal cancer do not recommend routine surveillance imaging. We aimed to analyze the method of recurrence detection in HPV+ disease to determine a role for follow-up imaging. All HPV+ and HPV- oropharyngeal cancer patients treated at our institution from 2005-2016 with biopsy-proven recurrence were identified and their method of recurrence detection was analyzed. A total of 16 HPV+ oropharyngeal cancer patients were identified to have recurrence, 12 (75%) of which experienced distant recurrence and 13 (81.3%) were detected asymptomatically with imaging at a median time of 19.7 months after initial treatment and verifying no residual disease. Twelve (75%) detections were with PET-CT. While HPV- patients (17 patients) also have a high rate of asymptomatic detection (16 patients, 94.1%), their 3-year post-recurrence survival was significantly lower at 6.5% compared to 83.6% for the HPV+ group (p<0.01). In HPV+ patients, a large proportion of failures are asymptomatic distant metastases, which occur beyond 6 months following treatment completion, and are detected with whole body imaging alone. In light of long term post-recurrence survival observed, this preliminary data suggests that routine surveillance imaging should be further studied for HPV+ disease.

2017-01-01

Background Needle aspiration and chest tube drainages are two main treatments for primary spontaneous pneumothorax (PSP). However, the application of needle aspiration or chest tube drainages has not reached a consensus. The aim of this study is to compare the needle aspiration with chest tube drainages in patients suffering with PSP and therefore help offer suggestions for clinical practice. Methods We searched literatures from PubMed, OVID and Web of Science from their inception to June 30, 2017. Continuous and dichotomous outcomes were expressed by weight mean difference (WMD) and risk ratio (RR) respectively, and each with 95% confidence intervals (CIs). We used the fixed effect or random effect model to perform quantitative synthesis. Results A total of 6 RCTs recruiting 458 participants were included in our analysis. On the basis of the six studies, our results indicated that compared with chest tube drainage applying needle aspiration shortened the hospital stay (WMD: ‒1.67 days; 95% CI: ‒2.25 to 1.08; P<0.001) and decreased hospitalization rate (RR: 0.40; 95% CI: 0.22–0.75; P=0.004). However, there was no difference regarding immediate success rate (RR: 1.01; 95% CI: 0.70–1.46; P=0.96) and one-year recurrence rate (RR: 0.89; 95% CI: 0.58–1.38; P=0.61). Conclusions In the light of this present research, it is necessary to apply needle aspiration into treating PSP to reduce hospitalization rate and shorten hospital stay. However, the two treatments have no significant difference with respect to immediate success rate, one-year recurrence rate, one-week success rate, three-month recurrence rate or complication rate.

Laboratory constraints on models of earthquake recurrence

Beeler, Nicholas M.; Tullis, Terry; Junger, Jenni; Kilgore, Brian D.; Goldsby, David L.

2014-01-01

In this study, rock friction ‘stick-slip’ experiments are used to develop constraints on models of earthquake recurrence. Constant-rate loading of bare rock surfaces in high quality experiments produces stick-slip recurrence that is periodic at least to second order. When the loading rate is varied, recurrence is approximately inversely proportional to loading rate. These laboratory events initiate due to a slip rate-dependent process that also determines the size of the stress drop [Dieterich, 1979; Ruina, 1983] and as a consequence, stress drop varies weakly but systematically with loading rate [e.g., Gu and Wong, 1991; Karner and Marone, 2000; McLaskey et al., 2012]. This is especially evident in experiments where the loading rate is changed by orders of magnitude, as is thought to be the loading condition of naturally occurring, small repeating earthquakes driven by afterslip, or low-frequency earthquakes loaded by episodic slip. As follows from the previous studies referred to above, experimentally observed stress drops are well described by a logarithmic dependence on recurrence interval that can be cast as a non-linear slip-predictable model. The fault’s rate dependence of strength is the key physical parameter. Additionally, even at constant loading rate the most reproducible laboratory recurrence is not exactly periodic, unlike existing friction recurrence models. We present example laboratory catalogs that document the variance and show that in large catalogs, even at constant loading rate, stress drop and recurrence co-vary systematically. The origin of this covariance is largely consistent with variability of the dependence of fault strength on slip rate. Laboratory catalogs show aspects of both slip and time predictability and successive stress drops are strongly correlated indicating a ‘memory’ of prior slip history that extends over at least one recurrence cycle.

Purpose: Investigation of the treatment potential of carbon-ion radiation therapy in pelvic recurrence of rectal cancer. Methods and Materials: A phase 1/2 dose escalation study was performed. One hundred eighty patients (186 lesions) with locally recurrent rectal cancer were treated with carbon-ion radiation therapy (CIRT) (phase 1/2: 37 and 143 patients, respectively). The relapse locations were 71 in the presacral region, 82 in the pelvic sidewalls, 28 in the perineum, and 5 near the colorectal anastomosis. A 16-fraction in 4 weeks dose regimen was used, with total dose ranging from 67.2 to 73.6 Gy(RBE); RBE-weighted absorbed dose: 4.2 to 4.6 Gy(RBE)/fraction. Results: Duringmore » phase 1, the highest total dose, 73.6 Gy(RBE), resulted in no grade >3 acute reactions in the 13 patients treated at that dose. Dose escalation was halted at this level, and this dose was used for phase 2, with no other grade >3 acute reactions observed. At 5 years, the local control and survival rates at 73.6 Gy(RBE) were 88% (95% confidence interval [CI], 80%-93%) and 59% (95% CI, 50%-68%), respectively. Conclusion: Carbon-ion radiation therapy may be a safe and effective treatment option for locally recurrent rectal cancer and may serve as an alternative to surgery.« less

This study aimed at estimating the efficiency of palivizumab in the prevention of Respiratory Syncytial Virus (RSV) infection and its sequelae in preterm infants (32 day 1 -35 day 0 weeks of gestational age -wGA-) in Spain. A decision-tree model was developed to compare health benefits (Quality Adjusted Life Years-QALYs) and costs of palivizumab versus a non-prophylaxis strategy over 6 years. A hypothetical cohort of 1,000 preterm infants, 32 day 1 -35 day 0 wGA (4.356 kg average weight) at the beginning of the prophylaxis (15 mg/kg of palivizumab; 3.88 average number of injections per RSV season) was analysed. The model considered the most recent evidence from Spanish observational and epidemiological studies on RSV infection: the FLIP II study provided hospital admission and Intensive Care Unit (ICU) admission rates; in-hospital mortality rate was drawn from an epidemiological study from 2004 to 2012; recurrent wheezing rates associated to RSV infection from SPRING study were adjusted by the evidence on the palivizumab effect from clinical trials. Quality of life baseline value, number of hospitalized infants and the presence of recurrent wheezing over time were granted to estimate QALYs. National Health Service and societal perspective (included also recurrent wheezing indirect cost) were analysed. Total costs (€, 2016) included pharmaceutical and administration costs, hospitalization costs and recurrent wheezing management annual costs. A discount rate of 3.0% was applied annually for both costs and health outcomes. Over 6 years, the base case analysis showed that palivizumab was associated to an increase of 0.0731 QALYs compared to non-prophylaxis. Total costs were estimated in €2,110.71 (palivizumab) and €671.68 (non-prophylaxis) from the National Health System (NHS) perspective, resulting in an incremental cost utility ratio (ICUR) of €19,697.69/QALYs gained (prophylaxis vs non-prophylaxis). Results derived from the risk-factors population subgroups analysed were in line with the total population results. From the societal perspective, the incremental cost associated to palivizumab decreased to an €1,253.14 (ICUR = €17,153.16€/QALYs gained for palivizumab vs non-prophylaxis). One-way and probabilistic sensitivity analyses confirmed the robustness of the model. The prophylaxis with palivizumab is efficient for preventing from RSV infections in preterm infants 32 day 1 -35 day 0 wGA in Spain.

To determine the long-term outcomes of patients with an isolated ovarian recurrence after fertility sparing surgery (FSS) for epithelial ovarian cancer (EOC) and to evaluate the recurrence rates (and location) according to the new 2014 International Federation of Gynecology and Obstetrics (FIGO) staging system. Retrospective multicenter study. Teams having reported recurrence after FSS for EOC. Four series comprising 545 patients undergoing FSS and 63 (12%) recurrences. FSS (salpingo-oophorectomy for a majority of cases) for EOC. Recurrences rates and characteristics of recurrent disease. Among 63 recurrent patients, 24 (38%) recurrences were isolated on the spared ovary, and 39 (62%) arose at an extraovarian site. Among the patients with an isolated ovarian recurrence, three patients died after a median follow-up period of 186 months (range: 28-294 months). Among the patients with recurrent extraovarian disease, 24 died and 7 were alive with persistent disease after a median follow-up period of 34 months (range: 3-231 months). The overall rate of isolated ovarian and extrapelvic recurrences was higher for grade 3 tumors (compared with grades 1/2). The long-term survival of patients with an isolated ovarian recurrence after FSS for EOC remains favorable. The prognosis of patients with an extraovarian recurrence is poor compared with those who have an isolated recurrent ovarian tumor. Grade 3 tumors (compared to grades 1/2) give rise to a higher rate of extraovarian recurrences. Copyright © 2015 American Society for Reproductive Medicine. Published by Elsevier Inc.

Purpose With improved patient care, better diagnosis, and more treatment options after tumor recurrence, outcomes after fluorouracil (FU) -based treatment are expected to have improved over time in early-stage colon cancer. Data from 18,449 patients enrolled onto 21 phase III trials conducted from 1978 to 2002 were evaluated for potential differences in time to recurrence (TTR), time from recurrence to death (TRD), and overall survival (OS) with regard to FU-based adjuvant regimens. Methods Trials were predefined as old versus newer era using initial accrual before or after 1995. Outcomes were compared between patients enrolled onto old- or newer-era trials, stratified by stage. Results Within the first 3 years, recurrence rates were lower in newer- versus old-era trials for patients with stage II disease, with no differences among those with stage III disease. Both TRD and OS were significantly longer in newer-era trials overall and within each stage. The lymph node (LN) ratio (ie, number of positive nodes divided by total nodes harvested) in those with stage III disease declined over time. TTR improved slightly, with larger number of LNs examined in both stages. Conclusion Improved TRD in newer trials supports the premise that more aggressive intervention (oxaliplatin- and irinotecan-based chemotherapy and/or surgery for recurrent disease) improves OS for patients previously treated in the adjuvant setting. Lower recurrence rates with identical treatments in those with stage II disease enrolled onto newer-era trials reflect stage migration over time, calling into question historical data related to the benefit of FU-based adjuvant therapy in such patients.

To investigate if laser atherectomy with adjunctive balloon angioplasty can improve endovascular treatment outcomes for femoropopliteal in-stent restenosis (ISR). A dual center study included 135 symptomatic patients (mean age 71 years; 76 men) who underwent endovascular treatment of femoropopliteal ISR between 2006 and 2013. Of these, 54 (40%) were treated with laser atherectomy and the remaining 81 patients with balloon angioplasty alone. Angiographic images were reviewed for lesion morphology and characteristics, TransAtlantic InterSociety Consensus (TASC) II classification, and distal runoff. Class I ISR was defined as focal lesions ≤50 mm, class II ISR as lesions >50 mm, and class III ISR as stent total occlusion. Recurrent ISR was determined by a peak systolic velocity ratio >2.4 by duplex ultrasound. Patients treated with laser atherectomy had longer mean ISR lesion length (222 vs 114 mm, p<0.001) and more class III ISR (69% vs 20%, p=0.001). There was no association between laser atherectomy and rates of recurrent restenosis or occlusion for patients with class I/II ISR, but there was a significantly lower rate of target lesion revascularization at 2 years among patients treated with laser atherectomy (14% vs 44%, p=0.05). In comparison, patients with class III ISR treated with laser atherectomy had lower rates of recurrent restenosis at 1 year (54% vs 91%, p=0.05) and 2 years (69% vs 100%, p=0.05). Patients with class III ISR treated with laser atherectomy also had lower rates of recurrent in-stent occlusion at 2-year follow-up (33% vs 71%, p=0.04). When used to treat complex ISR, including in-stent occlusions, laser atherectomy with adjunctive balloon angioplasty may be associated with improved patency. © The Author(s) 2015.

The transurethral resection of bladder tumor (TURBT) remains the most widely used method in the surgical treatment of the non-muscle invasive bladder tumor (NMIBT). Despite its popularity, the laser technique has been widely used in urology as an alternative, via the application of transurethral laser enucleation of bladder tumor. The aim of the present study was to compare the efficacy and feasibility between transurethral laser enucleation and transurethral resection of bladder tumor. A systematic search of the following databases was conducted: PubMed, Wed of Science, Cochrane Library, EMBASE, Google scholar, and Medline. The search included studies up to the 1st of January 2017. The outcomes of interest that were used in order to assess the two techniques included operation time, catheterization time, hospitalization time, obturator nerve reflex, bladder perforation, bladder irritation, 24-month-recurrence rate, and the postoperative adjuvant intravesical chemotherapy. A total of 13 trials with 2012 participants were included, of which 975 and 1037 underwent transurethral laser enucleation and transurethral resection of bladder tumor, respectively. No significant difference was noted in the operation time between the two groups, although significant differences were reported for the variables catheterization time, hospitalization time, obturator nerve reflex, bladder perforation, bladder irritation, and 24-month-recurrence rate. In the mitomycin and epirubicin subgroups, no significant differences were observed in the laser enucleation and TURBT methods with regard to the 24-month-recurrence rate. The laser enucleation was superior to TURBT with regard to the parameters obturator nerve reflex, bladder perforation, catheterization time, hospitalization time, and 24-month-recurrence rate. Moreover, laser enucleation can offer a more accurate result of the tumor's pathological stage and grade.

An intent-to-treat analysis of overall survival (ITT-OS) of cirrhotic patients with hepatocellular carcinoma (HCC) listed for living donor liver transplantation (LDLT) or brain-dead donor liver transplantation (BDLT) across 5 French liver transplant (LT) centers. Comparisons of HCC outcomes after LDLT and BDLT measured from time of transplantation have yielded conflicting results. Records from 861 cirrhotic patients with HCC consecutively listed for either LDLT (n = 79) or BDLT (n = 782) from 2000 to 2009 were analyzed for ITT-OS using a Cox model; and tumor recurrence using 2 competitive risk models. Tumor staging was similar between groups. In total, 162 patients dropped out (20.7%), all from Group BDLT (P < 0.0001). The postoperative mortality rate and the retransplantation rate were similar between LDLT and BDLT. At 5 years, no statistically significant difference was found in ITT-OS between LDLT and BDLT groups (73.2% vs 66.7%; P = 0.062). LDLT waitlist inclusion (hazard ratio: 0.61 (0.39-0.96); P = 0.034) and a time-of-listing MELD score ≥ 25 (hazard ratio: 1.93 (1.15-3.26); P = 0.014) were independent predictors of ITT-OS. Similar 5-year post-LT OS rates (73.2% and 73.0% for Group LDLT and Group BDLT, respectively; P = 0.407) and HCC recurrence rates (10.9% and 11.2% for Group LDLT and Group BDLT, respectively; P = 0.753) were found. Upon explant analysis, tumors exceeding the Milan criteria, macroscopic vascular invasion, and AFP score>2 were independent predictors of recurrence, whereas LT type was not. LDLT improves ITT-OS, and it is not a risk factor for tumor recurrence. Therefore, LDLT and BDLT should be equally encouraged in countries where both are available.

Recurrence of migraine headaches after treatment is common. The evidence regarding steroids for preventing migraine headache recurrence is controversial. This meta-analysis examined the effectiveness of steroids for prevention of recurrent headaches. Databases (PubMed, Embase and the Cochrane Library) and conference proceedings were searched for randomized controlled trials comparing steroids and placebo in the treatment of migraine headaches. Two independent reviewers assessed studies and extracted data. Relative risks (RRs) of headache recurrence and adverse events were calculated and reported with 95% confidence intervals (95% CIs). Eight studies with 905 patients were included. Pooled analysis showed that when steroids were added to standard abortive therapy they reduced the rate of moderate or severe headache recurrence after 24-72 h of follow-up evaluation (RR = 0.71; 95% CI = 0.59-0.86). There was no significant benefit of steroids compared with placebo in the proportion of totally resolved migraines (RR = 1.11; 95% CI = 0.94-1.32). The side effects of steroids are mild and not significant except for dizziness. Subgroup meta-analysis showed that parenteral dexamethasone tends to be more effective in reducing moderate or severe recurrent headaches (RR = 0.68; 95% CI = 0.55-0.84). However, no significant differences were found between oral administration and parenteral administration of steroids (P = 0.37). When steroids are added to standard abortive therapy for migraine headaches, they are effective and safe for preventing moderate or severe headache recurrence. © 2013 The Author(s) European Journal of Neurology © 2013 EFNS.

Some of our patients showed a recurrence of adhesive small bowel obstruction (ASBO) with nonoperative management. The aim of this study was to evaluate the parameters predicting the recurrence of ASBO in patients managed with a long tube. Of 234 patients with ASBO admitted from April 1998 to September 2002, a total of 91 who recovered with nonoperative management after long tube placement were enrolled in this retrospective clinical study. We divided them into two groups for follow-up: the recurrence group and the no-recurrence group. We compared baseline characteristics, the number of previous ASBO admissions, the number of abdominal operations, the interval from the onset of symptoms to long-tube insertion, the duration of long-tube placement, the type of the contrasted intestine through the long tube, the location of the long-tube tip, and the drainage volume through the long tube between the two groups. We then examined the cumulative recurrence rate. A significant difference was found in the number of previous ASBO admissions, the duration of long-tube placement (77 hours vs. 43 hours), the contrasted intestine through the long tube, and the location of the long-tube tip. By multivariate analysis, the duration of long-tube placement was an independent parameter predicting the recurrence of ASBO. These results suggest that the duration of long-tube placement might serve as a parameter for predicting recurrence of ASBO in patients managed with a long tube.

Adequate fruit and vegetable intake was suggested to protect against colorectal cancer and colorectal adenomas; however, several recent prospective studies reported no association. We examined the association between fruits and vegetables and adenomatous polyp recurrence in the Polyp Prevention Trial (PPT). The PPT was a low-fat, high-fiber, high-fruit, and vegetable dietary intervention trial of adenoma recurrence, in which there were no differences in the rate of adenoma recurrence in participants in the intervention and control arms of the trial. In this analysis of the entire PPT trial–based cohort, multiple logistic regression analysis was used to estimate the odds ratio (OR) of advanced and nonadvanced adenoma recurrence within quartiles of baseline and change (baseline minus the mean over 3 y) in fruit and vegetable intake, after adjustment for age, total energyy intake, use of nonsteroidal anti-inflammatory drugs, BMI, and gender. There were no significant associations between nonadvanced adenoma recurrence and overall change in fruit and vegetable consumption; however, those in the highest quartile of change in dry bean intake (greatest increase) compared with those in the lowest had a significantly reduced OR for advanced adenoma recurrence (OR = 0.35; 95% CI, 0.18–0.69; P for trend = 0.001). The median in the highest quartile of change in dry bean intake was 370% higher than the baseline intake. The PPT trial–based cohort provides evidence that dry beans may be inversely associated with advanced adenoma recurrence. PMID:16772456

To assess complications, local tumor recurrences, overall survival (OS), and estimates of cost-effectiveness for multisite cryoablation (MCA) of oligometastatic renal cell carcinoma (RCC). A total of 60 computed tomography- and/or ultrasound-guided percutaneous MCA procedures were performed on 72 tumors in 27 patients (three women and 24 men). Average patient age was 63 years. Tumor location was grouped according to common metastatic sites. Established surgical selection criteria graded patient status. Median OS was determined by Kaplan-Meier method and defined life-years gained (LYGs). Estimates of MCA costs per LYG were compared with established values for systemic therapies. Total number of tumors and cryoablation procedures for each anatomic site are as follows: nephrectomy bed, 11 and 11; adrenal gland, nine and eight; paraaortic, seven and six; lung, 14 and 13; bone, 13 and 13; superficial, 12 and nine; intraperitoneal, five and three; and liver, one and one. A mean of 2.2 procedures per patient were performed, with a median clinical follow-up of 16 months. Major complication and local recurrence rates were 2% (one of 60) and 3% (two of 72), respectively. No patients were graded as having good surgical risk, but median OS was 2.69 years, with an estimated 5-year survival rate of 27%. Cryoablation remained cost-effective with or without the presence of systemic therapies according to historical cost comparisons, with an adjunctive cost-effectiveness ratio of $28,312-$59,554 per LYG. MCA was associated with very low morbidity and local tumor recurrence rates for all anatomic sites, with apparent increased OS. Even as an adjunct to systemic therapies, MCA appeared cost-effective for palliation of oligometastatic RCC. Copyright © 2012 SIR. Published by Elsevier Inc. All rights reserved.

Compared with laparoscopic groin herniorrhaphy, the open procedure used in most former studies was Lichtenstein repair. However, unlike the totally extraperitoneal (TEP) or transabdominal preperitoneal (TAPP) laparoscopic techniques, Lichtenstein procedure is a premuscular but not preperitoneal repair. This retrospective study compared the outcomes between laparoscopic preperitoneal and open preperitoneal procedure-modified Kugel (MK) herniorrhaphy. Groin hernia patients older than 18 years who underwent open MK or laparoscopic preperitoneal herniorrhaphy in our hospitals between January 2008 and December 2010 were enrolled. Baseline characteristics, recurrence, and intraoperative, short-term, and long-term postoperative complications were recorded. Among the 1,760 included patients (530 open and 1,230 laparoscopic), 96.08% completed the follow-up (24-60 months). The patients in the open group were older than laparoscopic group (p < 0.001). More bilateral (91.45%) and recurrent (82.12%) hernia patients underwent laparoscopic procedures (p < 0.001 and p = 0.004, respectively). The overall recurrence rate was 0.71%, with no significant difference between the two approaches (p = 0.227). The overall complication rate was lower for the laparoscopic than the open approach (14.47 vs. 19.25%, p = 0.012), whereas the rates of life-threatening complications were similar (1.51 vs. 0.98%, p = 0.332). The laparoscopic group had significantly lower incidence rates of wound infection and chronic pain (p = 0.016 and p < 0.001, respectively), shorter operative time, lower visual analogue scale scores, and faster recovery than the open group (p < 0.001). As preperitoneal herniorrhaphy, both MK and laparoscopic (TEP/TAPP) procedures are safe and effective, with low incidence rates of life-threatening complications and recurrence. The laparoscopic approach is superior in terms of lower incidence rates of infection and chronic pain, shorter operative time, and faster recovery; however, careful surgical procedure selection and implementation of technical details are required.

Catamenial pneumothorax (CP) is a cause of recurrent pneumothorax in women of child-bearing age. Surgical treatment has been associated with high recurrence rates. We report our experience with a totally videothoracoscopic approach involving diaphragmatic repair, pleurectomy/abrasion, and hormonal treatment in patients with proven CP. This was a retrospective study of all patients with proven CP operated on by a single surgeon using a videothoracoscopic approach, diaphragmatic repair, and pleurectomy/pleural abrasion. A polytetrafluoroethylene mesh was used to cover the diaphragm in patients with pores or fenestrations. All patients received hormone therapy for 6 to 12 months postoperatively and were followed up to assess complications and recurrence. Twelve patients were identified as having CP. All patients except one had suffered right sided pneumothorax only. One patient also had a history of left-sided pneumothorax managed conservatively at another institution. All cases except one underwent a primary operation. One patient had previously had videothoracoscopic pleurodesis without diaphragm repair at another center. In all cases, findings typical of CP were identified within the pleural cavity, mainly on the diaphragm. In three patients, no diaphragmatic pores or fenestrations were noted. There were no postoperative complications and no mortality. Median follow-up was 45.8 28.6 months. One patient suffered a single episode of recurrence before starting hormonal therapy, treated conservatively. A totally videothoracoscopic approach to CP including diaphragmatic cover with a mesh and pleurectomy/pleural abrasion is feasible, safe, and highly effective. Routine hormonal treatment (gonadotropin-releasing hormone analog) may also help reduce recurrences.

Our aim was to assess the efficacy and complications of pelvic organ prolapse (POP) correction with transvaginal mesh (TVM). We retrospectively assessed patients who had undergone a repair of an apical (primary or recurrent) or recurrent POP using TVM in our department since 2007. Meshes used were Prolift®, Elevate®, and Surelift®. Satisfaction with surgery was assessed on a 0-10 scale. A total of 83 patients were included (33 Prolift®, 36 Elevate®, 14 Surelift®), with a mean age of 67.8 ± 9.7 years. Eighteen (21.6%) patients underwent a recurrent POP correction. Follow-up was 49 ± 34 months. Twelve (14.4%) symptomatic recurrences were identified, 3 of which required further surgery. Satisfaction was 8.7. Four (4.8%) vaginal exposures were detected, 2 of which required partial mesh removal. Three (3.6%) cases of dyspareunia and 1 (1.2%) case of mild pelvic pain were reported, which did not require further treatment. The use of TVM for apical or recurrent POP repair is effective and is associated with a high satisfaction rate while complications are infrequent. © 2018 S. Karger AG, Basel.

Dai, Qi; Duan, Chen; Liu, Quan; Yu, Hongmeng

The aim of this study was to evaluate the clinical efficacy and the effects on decreasing the recurrence of AFRS (allergic fungal rhinosinusitis) of a budesonide inhalation suspension delivered via transnasal nebulization to patients following endoscopic sinus surgery. Thirty-five patients were recruited into this study. Final diagnoses were reached using Bent and Kuhn's criteria. The eligible patients were randomly divided into two groups: the budesonide transnasal nebulization group (group A) and the topical nasal steroids group (group B). Nasal symptoms, Lund-Mackay scores, and Kupferberg grades were evaluated before surgery, after surgery and during the follow-up to assess the effects of these two approaches. A total of 30 patients with AFRS who were eligible were included in the study. Four of the 15 patients in group B (26.67%) developed recurrent disease, whereas no patients in group A developed recurrent disease. This difference was statistically significant (p=0.032). Nebulized budesonide is an effective and safe treatment for patients with AFRS following endoscopic sinus surgery, as evidenced by the reduced recurrence rate observed in the budesonide transnasal nebulization group relative to the topical nasal steroids group.

To describe the pattern of disease progression and to describe locoregional recurrence, distant recurrence, and death rates in breast cancer patients after complete treatment. Medical records of women diagnosed with breast cancer at two university affiliated tertiary care hospitals in the Northern Thailand that had complete treatments between 2006 and 2010 were traced. Extracted key information included patient clinical profiles and documented recurrence of cancer The causes of death were verified from breast cancer case registration database, death certificates through The Ministry of Internal Affairs'civil registration, by direct telephone contact, or by distributed prepaid postcards. Medical records of 829 women diagnosed with breast cancer without prior evidence ofdistant metastasis, and had complete recommended treatment were included. Six hundred thirty seven women had not experienced any events up to the end of the follow-up (76.8%). The first occurring events were focused and categorized into three distinct types, locoregional recurrence (n = 83, median follow-up time = 34.2 months), distant recurrence (n = 78, median follow-up time = 35.4 months), and death without any evidences of locoregional or distant recurrences (n = 12, median follow-up time = 36.7 months). Distant recurrence after locoregional recurrence was reported (n = 33). There were 109 patient who had died (breast cancer related death) up to the end of the follow-up (13.2%). The three types of consecutively occurring deaths were death after locoregional recurrence without any distant recurrences (n = 15), death after distant recurrence with locoregional recurrence (n = 21), and death after documenited distant recurrence without any locoregional recurrences (n = 61). The trend was that the rate of the first occurring locoregional recurrence was slightly higher than that of distant recurrence, The death rate in patients without any recurrences was much lower than in those experiencing prior recurrences. The rates of disease progression from local recurrence to distant recurrence and to death were approximately 5 to 7 times faster in patients who had experienced earlierprogressions.

To emphasize the importance of adequate primary surgery in cases of medullary carcinoma of the thyroid, 44 cases of treated medullary carcinoma of thyroid were retrospectively reviewed in Government General Hospital, Chennai between 1987 and 2002. Patients who underwent total thyroidectomy with only central compartment dissection were compared with those who had undergone total thyroidectomy with meticulous triple compartment (bilateral lateral and central groups) nodal dissection. The group of total thyroidectomy with only central compartment dissection had high rate of lymph nodal recurrence and persistent hypercalcitoninaemia when compared with the group of total thyroidectomy with meticulous triple compartment nodal dissection.

The feasibility and effectiveness of radiotherapy in the management of recurrent esophageal carcinoma (REC) is reported. A consecutive cohort of 54 patients with rcT1-4, rcN0-1, or cM0 recurrent esophageal carcinoma (69% squamous cell carcinoma, 31% adenocarcinoma) was treated between 1988 and 2010. The initial treatment for these patients was definitive radiochemotherapy, surgery alone, or neoadjuvant radiochemotherapy + surgical resection in 8 (15%), 33 (61%), and 13 (24%) patients, respectively. The median time to recurrence from initial treatment was 19 months (range 4-79 months). The site of the recurrence was anastomotic or local, nodal, or both in 63%, 30%, and 7% of patients, respectively. Salvage radio(chemo)therapy was carried out with a median dose of 45 Gy (range 30-68 Gy). Median follow-up time for surviving patients from the start of R(C)T was 38 months (range 10-105 months). Relief of symptoms was achieved in 19 of 28 symptomatic patients (68%). The median survival time was 12 months (95% confidence interval (CI) 7-17 months) and the median recurrence-free interval was 8 months (95% CI 4-12 months). The survival rates at 1, 2, and 3 years were 55 ± 7%, 29 ± 6%, and 19 ± 5%, respectively. The recurrence-free survival rates at 1, 2, and 3 years were 44 ± 7%, 22 ± 6%, and 15 ± 5%, respectively. A radiation dose ≥ 45 Gy and conformal RT were associated with a better prognosis. RT is feasible and effective in the management of recurrent esophageal carcinoma, especially for relief of symptoms. Toxicity is in an acceptable range. The outcome of REC is poor; however, long-term survival of patients with recurrent esophageal carcinoma after radiochemotherapy might be possible, even with a previous history of radiotherapy in the initial treatment. If re-irradiation of esophageal carcinoma is contemplated, three-dimensional conformal techniques and a minimum total dose of 45 Gy are recommended.

In a prospective randomized trial comparing the totally preperitoneal (TPP) laparoscopic approach and the Stoppa procedure (open), 100 patients with inguinal hernias (Nyhus IIIA, IIIB, IV) were followed over a 3-year period. Both groups were epidemiologically comparable. In the laparoscopic group, operating time was significantly longer (p = 0.01), but hospital stay (3.2 vs. 7.3 days) and delay in return to work (17 vs. 35 days) were significantly reduced (p = 0.01). Postoperative comfort (less pain) was better (p = 0.001) after laparoscopy. In this group, morbidity was also reduced (4 vs. 20%; p = 0.02). The mean follow-up was 605 days, and 93% of the patients were reviewed at 3 years. There were three (6%) recurrences after TPP, especially at the beginning of the surgeon's learning curve, versus one for the Stoppa procedure (NS). For bilateral hernias, the authors suggest the use of a large prosthesis rather than two small ones to minimize the likelihood of recurrence. In the conditions described, the laparoscopic (TPP) approach to inguinal hernia treatment appears to have the same long-term recurrence rate as the open (Stoppa) procedure but a real advantage in the early postoperative period.

We analyzed knee arthrodesis for the infected total knee replacement (TKR) using two different fixation techniques. Patients undergoing knee arthrodesis for infected TKR were identified and rates of successful fusion and recurrence of infection were compared using Cox proportional hazard models. Eighty-five consecutive patients who underwent knee arthrodesis were followed until union, nonunion, amputation, or death. External fixation achieved successful fusion in 41 of 61 patients and was associated with a 4.9% rate of deep infection. Fusion was successful in 23 of 24 patients with intramedullary (IM) nailing and was associated with an 8.3% rate of deep infection. We observed similar fusion and infection rates with the two techniques. Thirty-four patients (40%) had complications. Knee arthrodesis remains a reasonable salvage alternative for the difficult infected TKR. Complication rates are high irrespective of the technique, and one must consider the risks of both nonunion and infection when choosing the fixation method in this setting. IM nailing appears to have a higher rate of successful union but a higher risk of recurrent infection when compared with external fixation knee arthrodesis. Level III, therapeutic study.

Two-stage reimplantation for prosthetic joint infection reportedly has the lowest risk for recurrent infection. Most studies to date have evaluated revision surgery for infection using an anatomic prosthetic. As compared with anatomic prostheses, reverse total shoulder arthroplasty is reported to have a higher rate of infection. We determined reinfection rates, functional improvement, types and rates of complications, and influence of rotator cuff tissue on function for two-stage reimplantation for prosthetic joint infection treated with reverse shoulder arthroplasty. We retrospectively reviewed 27 patients treated with a two-stage reimplantation for prosthetic shoulder infection using a uniform protocol for management of infection; of these, 17 had reverse shoulder arthroplasty at second-stage surgery. Types of organisms cultured, recurrence rates, complications, function, and radiographic followup were reviewed for all patients. One of the 17 patients had recurrence of infection. The mean (± SD) Penn shoulder scores for patients treated with reverse shoulder arthroplasty improved from 24.9 ± 22.3 to 66.4 ± 20.8. The average motion at last followup was 123° ± 33° of forward flexion and 26° ± 8° of external rotation in patients treated with a reverse shoulder arthroplasty. The major complication rate was 35% in reverse shoulder arthroplasty, with five dislocations and one reinfection. There was no difference in final Penn score between patients with and without external rotation weakness. Shoulder function and pain improved in patients treated with a second-stage reimplantation of a reverse prosthesis and the reinfection rate was low. Level IV, case series.

Onyx is important embolic material in the endovascular treatment of intracranial dural arteriovenous fistula (DAVF). However, its impact on DAVF occlusion rates, morbidity, mortality, and complication rates is not fully examined. To improve understanding of safety and effectiveness profiles associated with transarterial endovascular treatment using Onyx for intracranial DAVF. We analyzed data from our prospective clinical registry and conducted a systematic review of all previous transarterial embolization studies using Onyx published between January 2005 and December 2015 in MEDLINE and EMBASE. In the prospective study, 41 transarterial procedures were performed in 33 consecutive patients harboring 36 DAVFs. Complete initial exclusion was obtained in 32 of 36 (88.9%) fistulas; 31 fistulas were followed up showing 4 (12.9%) recurrences. Procedure-related morbidity and mortality were 3% and 0%, respectively. The literature review identified 19 studies involving a total of 425 patients with 463 DAVFs. Meta-analysis, including our registry data, showed an initial complete occlusion rate of 82% (95% confidence interval [CI]: 74%, 88%; I2, 70.6%), and recurrence rate at midterm of 2% (95% CI: 0%, 5%; I2, 21.5%). Pooled postoperative neurological deficit, procedure-related morbidity, and mortality rates were 4% (95% CI: 2%, 6%; I2, 0%), 3% (95% CI: 1%, 5%; I2, 0%), and 0%, respectively. This meta-analysis suggests that transarterial embolization with Onyx is a safe treatment modality for DAVFs. Although Onyx showed a low recurrence rate at midterm, the long-term risk is poorly addressed in our study and should warrant a longer follow-up.

Colloid cysts are benign lesions, found in the anterior part of the roof of the third ventricle. A PubMED search of literature was performed to identify the evidence on different treatment options and surgical approaches for removal of colloid cysts. Evidence on endoscopic versus microsurgical resection of colloid cysts showed that microsurgical approach had significantly higher rates of gross total resection, lower recurrence rate and lower re-operation rate. No significant difference with respect to the mortality rate or the need for a shunt was found between the two groups. However, the overall morbidity rate was lower for the endoscopic group. .

Aim of the study was the evaluation of the role of adjuvant radiation therapy in the prevention of recurrence after excision. Between July 1, 1985 and April 1, 1993, 64 patients (43 male, 21 female) were referred to radiation therapy after excision of a nasal pterygium. Radiation therapy was done with a strontium-90 eye applicator and a total dose of 30 Gy, fractionated in 6 fractions of 5 Gy each, 3 times a week. Forty-nine patients were treated primarily, 15 patients underwent radiation therapy for the first time in case of recurrent pterygium after multiple re-excisions. All patients had a following of 1 to 9 years with a median of 5.5 years. In 8 of 64 irradiated patients recurrent pterygium was detected (12.5%). Differentiated into the 2 groups 4 of the primarily treated patients had recurrent pterygium (8.16%), the other 4 were in the group with multiple former re-excisions (26.7%). With regard to the initiation of the irradiation after surgery pterygium did not recur in any of the primarily treated patients who were irradiated in between 3 days after surgery. In contrary 3 of 7 primarily treated patients (42.9%) who started radiation therapy between 7 and 10 days after surgery had recurrent pterygium. For the patients with primarily recurrent pterygium no dependence of the initiation of radiation therapy after surgery could be detected. Adjuvant radiation therapy after excision of pterygium lowers the rate of recurrence from about 40% to 12.5%, in a primarily adjuvant situation to 8.16%. In these patients radiation therapy should be initiated within 3 days after surgery. Patients with primarily recurrent pterygium have an elevated risk of recurrence independently of the initiation of radiation therapy.

Background Evidence regarding the benefit of therapy to prevent the post-polypectomy recurrence of colorectal adenoma is limited. Endoscopic recurrence is the main outcome according to an evaluation of trials involving recurrence prevention. Aim To estimate the recurrence rates of post-polypectomy colorectal adenoma in placebo-controlled arms of randomized clinical trials and to identify the prognostic factors influencing these rates. Methods We combined data from all randomized controlled trials evaluating therapies for colorectal adenoma using placebo from 1988 to 2016. The data were combined in a random-effects model. Primary outcomes were endoscopic adenoma and advanced adenoma recurrence of colorectal adenoma. Results The pooled estimates of the adenoma recurrence rates were 37% (95% confidence interval [CI], 33%-41%; range, 33%-52%) at 1 year, 47% (95% CI, 41%-54%; range, 46%-51%) at 2 years, 41% (95% CI, 33%-48%; range, 20%-61%) at 3 years, 48% (95% CI, 38%-57%; range, 37%-53%) at 4 years, and 60% (95% CI, 52%-68%; range, 48%-68%) at 5 years. The pooled estimates of the advanced adenoma recurrence rates were 10% (95% CI, 6%-15%; range, 7%-13%) at 1 year, 12% (95% CI, 8%-16%; range, 3%-19%) at 3 years, 14% (95% CI, 10%-18%; range, 13%-16%) at 4 years, and 14% (95% CI, 10%-19%; range, 9%-21%) at 5 years. Significant heterogeneity among the randomized clinical trials (P < 0.001) was observed for each recurrence rate. Conclusions This meta-analysis confirms the heterogeneity of recurrence rates among post-polypectomy colorectal adenoma patients who received placebo. No single design variable was identified that might explain the heterogeneity. PMID:28977952

To estimate the impact of antiretroviral therapy (ART) on the incidence of recurrent tuberculosis (TB) in an African population. A long-term population cohort in Karonga District, northern Malawi. Patients who had completed treatment for laboratory-confirmed TB diagnosed since 1996 were visited annually to record vital status, ART use and screen for TB. Survival analysis estimated the effect of HIV/ART status at completion of treatment on mortality and recurrence. Analyses were stratified by time since treatment completion to estimate the effects on relapse (predominates during first year) and reinfection disease (predominates later). Among 1133 index TB cases contributing 4353 person-years of follow-up, there were 307 deaths and 103 laboratory-confirmed recurrences (recurrence rate 4.6 per 100 person-years). Half the recurrences occurred in the first year since completing treatment. HIV infection increased the recurrence rate [rate ratio adjusted for age, sex, period and TB type 2.69, 95% confidence interval (CI) 1.69-4.26], but with less effect in the first year (adjusted rate ratio 1.71, 95% CI 0.87-3.35) than subsequently (adjusted rate ratio 4.2, 95% CI 2.16-8.15). Recurrence rates on ART were intermediate between those of HIV-negative individuals and HIV-positive individuals without ART. Compared with HIV-positive individuals without ART, the adjusted rate ratio was 0.74 (95% CI 0.27-2.06) in the first year, and 0.43 (95% CI 0.11-1.73) later. The increased incidence of TB recurrence observed in HIV-positive patients appeared to be reduced by ART. The effects are mostly on later (likely reinfection) disease so the impact of ART on reducing recurrence will be highest in high TB incidence settings.

Purpose: The aim of this study was to evaluate the results of keloidectomy and strontium 90 brachytherapy in the prevention of keloid recurrence following excision and to identify outcome and the prognostic factors that predict keloid recurrence after irradiation. Methods and Materials: Data of 612 patients with 892 keloids treated between 1992 and 2006 were evaluated retrospectively. Brachytherapy was performed using a Sr-90Y surface applicator. Total dose was 20 Gy in 10 fractions. Results: With a median follow-up of 61 months, the overall recurrence-free response rate for all keloids was 87.6%. Multivariate analysis revealed the following prognostic factors for recurrence:more » keloid size > 5 cm (p < 0.0001), burn scars as the keloid etiology (p < 0.0001), and previous treatment (p < 0.0001). Outcome was not found to be significantly related to the interval between surgery and radiotherapy, sex, or age. Pruritus and skin reddening were the most common symptoms of keloids, but all signs and symptoms abated with time after treatment. Cosmetic results from the keloid treatment were considered good or excellent in 70.6% of the patients. Conclusion: Our study findings show that excision plus Sr-90 brachytherapy is effective in the eradication of keloids. Sr-90 radiotherapy (20 Gy in 10 fractions) achieved a similar local control rate, as have higher doses per fraction in other series. It also resulted in a good cosmetic rate and relief of symptoms. Our data further suggest that the initiation of postoperative irradiation within hours of surgical excision is not important to therapeutic outcome.« less

To investigate the activity of 5% Imiquimod cream in the primary treatment of vulva intraepithelial neoplasia (VIN) grade 2/3. Patients with histologically confirmed VIN 2/3 were recruited from regional colposcopy units. A Simon two-stage phase 2 study design was used. Imiquimod cream was applied over the abnormal VIN areas by the patients, using an escalating dose regimen for a total treatment duration of 16 weeks. Colposcopy assessments were performed every 2 weeks to evaluate for response. A historical cohort of VIN 2/3 patients treated with primary surgical ablation was used to compare recurrence patterns. Thirty-nine patients enrolled in the study. Six patients dropped out due to side effects and non-compliance with study protocol. Thirty-six patients (92%) had VIN 3. Therapy was well tolerated with the most common observed side effects being only minor skin irritation at the application site. Histologic complete response was observed in 21 patients with partial response in another nine patients. The overall response rate was 77% using intention to treat principle. No VIN progression or cancer was diagnosed. At a median follow-up of 16 months in the whole study cohort, eight recurrences (20.5%) were observed. In comparison, the recurrence rate for primary surgically treated patients was 53.5% (p=0.013). Imiquimod cream was well tolerated and resulted in the regression in a majority of high-grade VIN lesions. The recurrence rate appeared to be comparable to primary surgical ablation.

Bone tumor resections for limb salvage have become the standard treatment. Recently, intercalary tumor resection with epiphyseal sparing has been used as an alternative in patients with osteosarcoma. The procedure maintains normal joint function and obviates some complications associated with osteoarticular allografts or endoprostheses; however, long-term studies analyzing oncologic outcomes are scarce, and to our knowledge, the concern that a higher local recurrence rate may be an issue has not been addressed. We wanted to assess (1) the overall survival in patients treated with this surgical technique; (2) the percentage of local recurrence and limb survival, specifically the incidence of recurrence in the remaining epiphysis; (3) the frequency of orthopaedic complications, and, (4) the functional outcomes in patients who have undergone intercalary tumor resection. We analyzed all 35 patients with osteosarcomas about the knee (distal femur and proximal tibia) treated at our center between 1991 and 2008 who had resection preserving the epiphysis and reconstruction with intercalary allografts. Minimum followup was 5 years, unless death occurred earlier (mean, 9 years; range, 1-16 years), and no patients were lost to followup. During the study period, our indications for this approach included patients without metastases, with clinical and imaging response to neoadjuvant chemotherapy, that a residual epiphysis of at least 1 cm thickness could be available after a surgical margin width in bone of 10 mm was planned, and 16% of patients (35 of 223) meeting these indications were treated using this approach. Using a chart review, we ascertained overall survival of patients, oncologic complications such as local recurrence and tumor progression, limb survival, and orthopaedic complications including infection, fracture, and nonunion. Survival rates were estimated using the Kaplan-Meier method. Patient function was evaluated using the Musculoskeletal Tumor Society (MSTS)-93 scoring system. Overall survival rate of the patients was 86% (95% CI, 73%-99%) at 5 and 10 years. Five patients died of disease. No patient had a local recurrence in the remaining bony epiphysis, but three patients (9%; 95% CI, 0%-19%) had local recurrence in the soft tissue. The limb survival rate was 97% (95% CI, 89%-100%) at 5 and 10 years. Complications treated with additional surgical procedures were recorded for 19 patients (54%), including three local recurrences, two infections, 11 fractures, and three nonunions. In 10 of these 19 patients, the allograft was removed. Only five of the total 35 study patients (14%) lost the originally preserved epiphysis owing to complications. The mean functional score was 26 points (range, 10-30 points, with a higher score representing a better result) at final followup. Although the recurrence rate was high in this series, the small sample size means that even one or two fewer recurrences might have resulted in a much more favorable percentage. Because of this, future, larger studies will need to determine whether this is a safe approach, and perhaps should compare epiphyseal preservation with other possible approaches, including endoprosthetic reconstruction and/or osteoarticular allografts.

The Polyp Prevention Trial (PPT) was a multicenter randomized clinical trial designed to determine the effects of a high-fiber, high-fruit and vegetable, low-fat diet on the recurrence of adenomatous polyps in the large bowel. Detailed dietary intake and supplement use data were collected at baseline and at each of 4 annual study visits. Adenoma recurrence was ascertained by complete colonoscopy at baseline and after 1 and 4 y. Recurrence was found in 754 of the 1905 trial participants. We evaluated the association between calcium and vitamin D intake and adenomatous polyp recurrence after adjusting for intervention group, age, gender, nonsteroidal anti-inflammatory drug use, total energy intake, and the interaction of gender and intervention group. Vitamin D models were also adjusted for the location of the clinic site. Dietary variables were adjusted for total energy intake via the residual method. There were no overall significant associations between adenoma recurrence and dietary calcium intake [odds ratio (OR) for the 5th compared with the lowest quintile = 0.91; 95% CI = 0.67-1.23; P-trend = 0.68], total calcium intake (OR = 0.86; 95% CI = 0.62-1.18; P-trend = 0.20), or dietary vitamin D intake (OR = 0.93; 95% CI = 0.69-1.25; P-trend = 0.43) averaged over follow-up. Total vitamin D intake was weakly inversely associated with adenoma recurrence (OR = 0.84; 95% CI = 0.62-1.13; P-trend = 0.03). Supplemental calcium and vitamin D use during follow-up also were inversely associated with adenoma recurrence (OR for any compared with no use = 0.82; 95% CI = 0.68-0.99; and OR = 0.82; 95% CI = 0.68-0.99; for calcium and vitamin D, respectively). Slightly stronger associations were noted for the prevention of multiple recurrences. Our analyses did not suggest a significant effect modification between total calcium and total vitamin D intake (P = 0.14) on risk for adenoma recurrence. This trial cohort provides some evidence that calcium and vitamin D may be inversely associated with adenoma recurrence.

To perform a meta-analysis to determine the effect of radiotherapy (RT) on nipple-areolar complex (NAC) and skin flap necrosis, and local recurrence in women who undergo nipple-sparing mastectomy (NSM) and immediate breast reconstruction. Medline, PubMed, Cochrane, and Google Scholar databases were searched until October 16, 2015. Randomized-controlled-trials, prospective, retrospective, and cohort studies were included. The primary outcome was the NAC necrosis rate, and the secondary outcomes were the skin flap necrosis and local recurrence rates. Of 186 studies identified, 2 prospective and 5 retrospective studies including a total of 3692 patients were included in the meta-analysis. Five, 3, and 2 studies reported data of NAC necrosis (3461 breasts), skin flap necrosis (2490 breasts), and local recurrence (988 breasts), respectively. Pooled results showed no difference in the odds of NAC necrosis [odds ratio (OR) = 1.250, 95% confidence interval (CI) 0.481-3.247, P = 0.647], or local recurrence (OR = 0.564, 95% CI 0.056-5.710, P = 0.627) between patients who received and did not receive RT. Patients treated with RT had a higher likelihood of skin flap necrosis (OR = 2.534, 95% CI 1.720-3.735, P < 0.001). Significant heterogeneity, however, was noted in the analysis of NAC and local recurrence. Because of the limitations of the small number of studies and heterogeneity in the analysis, this study does not allow drawing any definitive conclusions and highlights the need of well-controlled trials to determine the effect of RT in patients undergoing NSM.

Tenosynovial giant-cell tumour or pigmented villonodular synovitis is an aggressive synovial proliferative disease, with the knee joint being the most commonly affected joint. The mainstay of therapy is surgical resection. The aim of this study was to evaluate the main patient characteristics, treatment and outcomes in a large single-centre retrospective study, focusing on meticulous aggressive open surgical procedures. From 1996 through 2014, 122 surgical interventions were performed in 105 patients. All patients underwent open synovectomy and when the knee joint was affected, combined anterior and posterior synovectomy. Radiotherapy was applied in 2 patients, radiosynoviorthesis in 27 patients. In histopathology, the diffuse type was seen in 66 (54%) lesions. Two patients were lost during follow-up. At a median follow-up time of 71 months (range: 13-238), 22 (18%) lesions recurred within a median of 18 months, >90% in the first 3 years. Out of those 22 recurrences, 9 (11%) were seen in primary disease and 13 (34%) were a second recurrence. After renewed resection, 6 (5%) out of the 120 resections had persistent tumour at the end of follow-up. Based on the number of patients with complete follow-up (n = 103), this represents 5.8%. In diffuse-type pigmented villonodular synovitis, total synovectomy might be difficult to achieve. As shown in our results and also in the literature, meticulous open resection, especially in difficult to approach areas such as the popliteal space, reduces local recurrence rates. External beam radiation is an option in prevention of otherwise non-operable local recurrences or in non-operable disease.

Ablation of atrioventricular nodal re-entrant tachycardia (AVNRT) is a highly effective procedure both with radiofrequency (RF) and cryoenergy (CE). Conventionally, it requires several diagnostic catheters and hospital admission. This study assessed the safety and efficacy of a highly simplified approach using the magnetic navigation system (MNS) compared to CE and manual RF ablation (MAN). In the MNS group a single magnetic-guided quadripolar catheter was inserted through the internal jugular vein to perform ablation. In the CE group cryomapping preceded ablation and for MAN procedures conventional ablation was performed. The following parameters were analysed: success- and recurrence rate, procedure-, fluoroscopy- and total application time. In total 69 eligible patients were treated with MNS (n = 26), CE (n = 25) and MAN (n = 16). The success rates were 100%, 100% and 94%, respectively (p = ns). The mean procedural time was 83 +/- 25 min for MNS, 117 +/- 47 min for CE and 117 +/- 55 min for MAN (P < 0.01). Total radiation time was significantly lower for MNS [0.0 min (IQR 0.0-0.0)] compared to CE [15.1 min (IQR 9.1-23.8), P < 0.001] and MAN [17.5 min (IQR 7.0-31.3), P < 0.001]. The total application time was comparable for both RF groups: 357 +/- 315 s (MNS) vs 204 +/- 177 s (MAN) (P = 0.14). No major adverse events occurred. After 3 months follow-up similar PR intervals were recorded for all patients. During a follow-up of 26 +/- 5 months recurrence rates were 3.8%, 4.0% and 6.3%, respectively, for each group. The MNS-guided single-catheter approach is a feasible and safe technique for the treatment of patients with typical AVNRT.

Variations in ankle injury rates and distributions among competition levels are unclear, but such data may help inform strategies to prevent ankle sprains during American football. To describe the epidemiological patterns of ankle sprains in youth, high school (HS), and collegiate American football. Descriptive epidemiological study. Data regarding youth, HS, and college football athletes were collected from 3 injury surveillance programs: (1) the Youth Football Safety Study (YFSS), (2) the National Athletic Treatment, Injury and Outcomes Network (NATION), and (3) the National Collegiate Athletic Association (NCAA) Injury Surveillance Program (ISP). During the 2012-2014 seasons, the YFSS, NATION, and NCAA ISP included 310, 184, and 71 football team-seasons, respectively. Athletic trainers (ATs) attended each practice and game and reported injuries and athlete-exposures (AEs) via their preferred injury documentation application. Ankle sprain rates for each type of ankle sprain were calculated overall, by event type (ie, practices and games), and specifically for severe injuries (ie, participation restriction time >21 days) and recurrent injuries (as defined by ATs). Rate ratios (RRs) were used to compare ankle sprain rates by competition level and event type. Injury proportion ratios (IPRs) were used to compare differences in severity, surgical needs, recurrence, injury mechanism, and injury activity by competition level. RRs and IPRs with 95% confidence intervals excluding 1.00 were considered statistically significant. A total of 124, 897, and 643 ankle sprains were reported in youth, HS, and college football, respectively. This led to respective rates of 0.59, 0.73, and 1.19 sprains per 1000 AEs. The ankle sprain rate in college football was higher than the rates in HS (RR = 1.64; 95% CI, 1.48-1.82) and youth (RR = 2.01; 95% CI, 1.65-2.43) football. The proportion of ankle sprains that were recurrent in youth football was higher than the proportions in HS (IPR = 2.73; 95% CI, 1.68-4.50) and college (IPR = 2.19; 95% CI, 1.33-3.61) football. Ankle sprain rates were highest in college athletes. However, level-specific variations in ankle sprain severity and recurrence may highlight the need to develop level-specific policies and prevention strategies to reduce injury incidence.

One thousand one hundred twenty-seven cases of nasopharyngeal carcinoma were treated with routine radiotherapy from October 1969 to March 1976, of which 436 cases have survived for more than 5 years, 323 cases have survived for over 10 years. The follow-up rate was 98.4%. The present paper analyzes the factors involved in these 436 cases. All patients were treated with tele60Co unit, and in the neck some cases were treated with orthovoltage therapy. The total dose to the primary lesion was 60-75 Gy in 6-8 weeks and in a few cases over 80 Gy were needed, and 50 Gy were applied bilateral cervical lymphatic chain. In this series of cases the 10-year overall survival rate was 28.7%, with Stage I being 66.7%, Stage II 46.5%, Stage III 28.0%, and Stage IV 18.6%, respectively. Statistically, 68 cases died of cardiovascular and other diseases and should be eliminated for net survival calculations. Therefore, we could obtain an actual 10-year survival rate of 30.5%. However, it should be noted that most of these cases were advanced, with Stage III, IV accounting for 82.3%, thus at Stage I, II the 10-year survival rate was 48%, while at Stage III, IV rate was down to 24.5%, which was statistically significant (p less than 0.01). Local and cervical recurrence as well as distant spread of diseases, for these cases started from the fifth to the tenth year after radiotherapy, the mortality caused by the above-mentioned three sites together was 76.9%. According to these findings, we propose that follow-up after radiotherapy in NPC exceeds 10-years. Of the 323 NPC cases, 10 were nasopharyngeal local recurrence which were re-irradiated, accounting for 3.1%. This paper shows that the 3-year survival rate in the local recurrence which were re-irradiated was 34.5%, the 5-year survival rate was 14.8%, and the 10-year survival rate was 11.5%. The failure after re-irradiation was caused by local recurrence and metastasis with a mortality of 83.6%. These results emphasize that the success of initial irradiation is important.

Postoperative RT is generally recommended for laryngeal carcinomas (LSCCs) at high risk of recurrence after surgery. There are currently no clinicopathological parameters available to predict response to such adjuvant RT in LSCC, and only a few potentially predictive biomarkers have been investigated. Nm23-H1 protein is reportedly related to the tumor cells' metastatic potential, and low Nm23-H1 expression levels in human carcinomas often correlate with a poor prognosis. The novel aim of the present preliminary study was to investigate the prognostic value of Nm23-H1 expression and subcellular localization in a series of patients given postoperative RT for LSCC. A retrospective clinicopathological investigation was conducted at an academic tertiary referral center of 28 consecutive patients given postoperative RT for LSCC. Image analysis of immunohistochemical reactions was performed to measure Nm23-H1 total and nuclear expression levels. Disease-free survival (DFS) was significantly shorter among LSCC patients with total Nm23-H1 levels <50.0 % (p = 0.03); the mean total Nm23-H1 expression was lower in patients with recurrent disease than in patients without it (statistical trend, p = 0.07). The disease recurrence rate was significantly higher (p = 0.021) and the DFS shorter (statistical trend, p = 0.052) among LSCC patients with nuclear Nm23-H1 levels <5.0 %. The locoregional recurrence-risk ratio in LSCC patients with nuclear Nm23-H1 levels <5.0 % was 9.16. Nm23-H1 warrants further investigation of its potential role as a predictive biomarker with a view to providing tailored treatments after surgery, such as combinations of chemotherapy and RT instead of RT alone, in patients whose LSCCs have low or no Nm23-H1 expression.

The purpose of this study is to describe the recurrence risk for hyperemesis gravidarum (HG). Women who registered on a Web site sponsored by the Hyperemesis Education and Research Foundation as having had one HG-complicated pregnancy were contacted to follow-up on a subsequent pregnancy. Participants completed an online survey. One hundred women responded. Fifty-seven had become pregnant again, 2 were trying to conceive, 37 were not willing to get pregnant again because of HG, and 4 did not have a second pregnancy for other reasons. Among the 57 women who responded that they had become pregnant again, 81% reported having severe nausea and vomiting in their second pregnancy. Among the women reporting recurrent HG, 98% reported losing weight and taking prescribed medication for HG, 83% reported treatment with intravenous fluids, 20% reported treatment with total parenteral nutrition or nasogastric tube feeding, and 48% reported hospitalization for HG. This study demonstrates both a high recurrence rate of HG and a large percentage of women who change reproductive plans because of their experiences with HG. © 2011 by the American College of Nurse-Midwives.

To evaluate the safety and efficacy of re-irradiation with carbon-ion radiotherapy (C-ion RT) for lymph node recurrence of gynecological cancers after definitive radiotherapy. Data regarding patients with unresectable and isolated recurrent lymph node from gynecological cancer after definitive radiotherapy were analyzed. Total dose of C-ion RT was 48-57.6 Gy (RBE) in 12 or 16 fractions. Sixteen patients received re-irradiation by C-ion RT were analyzed. Median follow-up was 37 months. Median tumor size was 27 mm. None developed Grade 1 or higher acute toxicities and Grade 3 or higher late toxicities. The 3-year overall survival, local control and disease-free survival rates after C-ion RT were 74%, 94% and 55%, respectively. Re-irradiation with C-ion RT for lymph node recurrence of gynecological cancers after definitive radiotherapy can be safe and effective. This result suggested that C-ion RT could be a curative treatment option for conventionally difficult-to-cure patients. Copyright© 2017, International Institute of Anticancer Research (Dr. George J.

This study examined whether lawyers' attributions of responsibility for mental illnesses affect their decisions about involuntary treatment. A survey that was mailed in 2003 to Illinois lawyers involved in involuntary commitment elicited recommendations for involuntary treatment for characters presented in vignettes. The survey also sought respondents' attributions of personal responsibility for the onset and recurrence of mental illnesses. A total of 89 lawyers responded to the survey, a response rate of 48 percent. Decisions to hospitalize persons with mental illness involuntarily increased significantly with the level of risk of harm and were significantly related to attributions of responsibility for the recurrence of mental illness. Decisions to recommend involuntary medication were not related to attributions of responsibility.

To determine the value of dissecting the recurrent laryngeal nerve during thyroid surgery with respect to preventing recurrent laryngeal nerve injury, we retrospectively analyzed clinical data from 5 344 patients undergoing thyroidectomy. Among these cases, 548 underwent dissection of the recurrent laryngeal nerve, while 4 796 did not. There were 12 cases of recurrent laryngeal nerve injury following recurrent laryngeal nerve dissection (injury rate of 2.2%) and 512 cases of recurrent laryngeal nerve injury in those not undergoing nerve dissection (injury rate of 10.7%). This difference remained statistically significant between the two groups in terms of type of thyroid disease, type of surgery, and number of surgeries. Among the 548 cases undergoing recurrent laryngeal nerve dissection, 128 developed anatomical variations of the recurrent laryngeal nerve (incidence rate of 23.4%), but no recurrent laryngeal nerve injury was found. In addition, the incidence of recurrent laryngeal nerve injury was significantly lower in patients with the inferior parathyroid gland and middle thyroid veins used as landmarks for locating the recurrent laryngeal nerve compared with those with the entry of the recurrent laryngeal nerve into the larynx as a landmark. These findings indicate that anatomical variations of the recurrent laryngeal nerve are common, and that dissecting the recurrent laryngeal nerve during thyroid surgery is an effective means of preventing nerve injury.

Topical wound oxygen (TWO(2)) proposes an option in the management of refractory nonhealing venous ulcers (RVUs). End points are proportion of ulcers healed at 12 weeks, recurrence rates, reduction in ulcer size, and time to full healing. A total of 67 patients with RVU were managed using TWO(2) and 65 patients with conventional compression dressings (CCDs) for 12 weeks or till full healing. Mean reduction in ulcer surface area at 12 weeks was 96% in patients managed with TWO(2) and 61% in patients managed with CCD. At 12 weeks, 76% of the TWO(2)-managed ulcers had completely healed, compared to 46% of the CCD-managed ulcers (P < .0001). Median time to full healing was 57 days in patients managed with TWO(2) and 107 days in patients managed with CCD (P< .0001). After 36 months follow-up, 14 of the 30 healed CCD ulcers showed recurrence compared to 3 of the 51 TWO(2)-healed ulcers. The TWO(2) is effective and valuable in managing RVU. The TWO(2) slashes the time required for RVU healing and radically decreases the recurrence rates.

Background: We evaluated the efficacy of imatinib mesylate in addition to hydroxyurea in patients with recurrent glioblastoma (GBM) who were either on or not on enzyme-inducing anti-epileptic drugs (EIAEDs). Methods: A total of 231 patients with GBM at first recurrence from 21 institutions in 10 countries were enrolled. All patients received 500 mg of hydroxyurea twice a day. Imatinib was administered at 600 mg per day for patients not on EIAEDs and at 500 mg twice a day if on EIAEDs. The primary end point was radiographic response rate and secondary end points were safety, progression-free survival at 6 months (PFS-6), and overall survival (OS). Results: The radiographic response rate after centralised review was 3.4%. Progression-free survival at 6 months and median OS were 10.6% and 26.0 weeks, respectively. Outcome did not appear to differ based on EIAED status. The most common grade 3 or greater adverse events were fatigue (7%), neutropaenia (7%), and thrombocytopaenia (7%). Conclusions: Imatinib in addition to hydroxyurea was well tolerated among patients with recurrent GBM but did not show clinically meaningful anti-tumour activity. PMID:19904263

The year 2015 marks the 30th anniversary of the publication of NSABP-R01, a landmark trial demonstrating the benefit of adding pelvic radiation to the treatment regimen for locally advanced rectal cancer with a resultant decrease in local recurrence from 25% to 16%. These results ushered in the era of multimodal therapy for rectal cancer, heralding modern treatment and changing the standard of care in the United States. We have seen many advances over the past 3 decades, including optimization of the administration and timing of radiation, widespread adoption of total mesorectal excision (TME), and the implementation of more effective systemic chemotherapy. The current standard is neoadjuvant chemoradiation with 5-fluorouracil (5-FU) and a radiosensitizer, TME, and adjuvant chemotherapy including 5-FU and oxaliplatin. The results of this regimen have been impressive, with a reported local recurrence rate of less than 10%. However, the rates of distant relapse remain 30% to 40%, indicating room for improvement. In addition, trimodality therapy is arduous and many patients are unable to complete the full course of treatment. In this article we discuss the current standard of care and alternative strategies that have evolved in an attempt to individualize therapy according to risk of recurrence.

The treatment of hypercortisolism for patients with bilateral adrenal disease (BAD) is controversial. Bilateral total adrenalectomy results in permanent hypocortisolaemia requiring lifelong steroid replacement. A more conservative surgical approach, with less than bilateral total adrenalectomy (leaving functional adrenal tissue either unilaterally or bilaterally), represents an alternative option; however, long-term outcome or recurrence data are limited. We report our experience with the surgical management of hypercortisolism caused by BAD. Between 2004 and 2016, 42 patients (12 male, 30 female; mean age 58 ± 10 years) with clinical or subclinical Cushing's syndrome (CS/sCS) caused by BAD underwent adrenal surgery via the posterior retroperitoneoscopic approach. Adrenal surgery was defined as "adrenalectomy" when total gland excision was performed or "resection" when a partial or subtotal adrenal resection was performed. Clinical, radiological and biochemical parameters were evaluated preoperatively and postoperatively. Seventy adrenal operations performed in total included unilateral resection (n = 3), unilateral adrenalectomy (n = 15), bilateral resection (n = 9), adrenalectomy and contralateral resection (n = 14) and bilateral total adrenalectomy (n = 3). Median operating time was 47.5 min (30-150) with no difference between unilateral and bilateral (synchronous included) procedures (p = 0.15). Mortality was zero. Clavien-Dindo grade of postoperative complications was I (n = 5) and IV (n = 3). All but one patient with CS and 17/31 patients with sCS received postoperative steroid supplementation for a median duration of 20 (1.5-129) months. After median follow-up of 40 months (3-129), the remission rate was 92%; 11 patients required ongoing steroid supplementation. There were three biochemical recurrences (two underwent contralateral resection); two patients with new/progressive radiological nodularity are biochemically eucortisolaemic. A significant reduction in BMI (p = 0.01) and antihypertensive requirements (p = 0.04) was observed postoperatively. A surgical approach which facilitates the conservation of functional adrenal tissue represents a suitable strategy for hypercortisolism caused by BAD. This approach avoids the necessity for lifelong steroid replacement in the majority of cases with low rates of adrenal insufficiency and recurrence.

Lo, Andrea C.; Morris, W. James, E-mail: JMorris@bccancer.bc.ca; Pickles, Tom

Objectives: This study examined patterns of recurrence after low–dose-rate prostate brachytherapy (LDR-PB), estimated local recurrence rate and compared that rate to the estimated local recurrence rate after radical prostatectomy (RP). Methods and Materials: A prospective database was maintained with clinical, dosimetric, and outcome data for all LDR-PB implantation procedures performed at our institution. From 1998 to 2008, 2223 patients with prostate cancer received LDR-PB without supplemental external beam radiation therapy. Patients who developed Phoenix-defined biochemical failure were reviewed for sites of relapse and investigations completed. Results: At a median follow-up of 5 years, 108 of 2223 patients (4.8%) developed biochemical relapse.more » In 1 additional patient, local relapse was found on transurethral prostate resection, but his prostate-specific antigen concentration was well short of triggering Phoenix-defined failure. Of the 109 patients with disease relapse, 18 of 2223 (0.8%) had a proven local recurrence, and 30 of 2223 (1.3%) had a proven distant recurrence. The remaining 61 of 2223 patients (2.7%) had unidentified sites of recurrence; of these, 57 patients (93%) had digital rectal examinations (DREs), 18 (30%) had post-treatment biopsies, 45 (74%) had bone scans, and 34 (56%) had computed tomography imaging of the abdomen and pelvis. If every biochemical failure were local, the local recurrence rate would be as high as 4.9%; however, by excluding those with proven distant failure and those with both a negative DRE and biopsy, we estimate that the local recurrence rate is 2.7% or less. Conclusions: In the context of limitations of the study design, our population-based analysis indicates that the local recurrence rate after LDR-PB is as low or lower than that after RP in our jurisdiction.« less

Few studies have followed patients who received antibiotic treatment for acute cholecystitis (AC). The present retrospective study investigated recurrence rates of AC and analyzed factors associated with recurrence after antibiotic treatment in adult AC patients. We analyzed patients treated with antibiotics for AC between October 1, 2004, and November 30, 2010. A Cox proportional hazards model was used to identify factors associated with early recurrence. Generalized additive models were applied to detect the nonlinear effects of continuous covariates. The study included 226 patients (mean age: 62.2 years; 144 men [63.7 %]). The average duration of parenteral antibiotics was 8.0 days. Second-generation cephalosporins were administered to 199 patients (88.1 %). The Kaplan-Meier plot indicated that recurrences were more frequent within 100 days of AC; these were defined as early recurrences. The recurrence rate was 13.7 % (31/226) at a median follow-up of 308.5 days (early recurrences: 19/226 [8.4 %]). The duration of parenteral antibiotic use significantly correlated with early recurrence (hazard ratio: 0.83; 95 % confidence interval, 0.73-0.95; p = 0.005). Generalized additive models revealed that patients using parenteral antibiotics longer than 8 days were less likely to suffer from early recurrence. The rate of recurrence of AC in patients who received antibiotics alone was low. The recurrence rate was higher within 100 days of AC. Because of the inherent limitations of a retrospective study, further research is needed to identify factors associated with early recurrence.

Recurrent oropharyngeal squamous cell carcinoma causes great morbidity and mortality. This systematic review analyses survival outcomes following salvage surgery for recurrent oropharyngeal squamous cell carcinoma. A comprehensive search of various electronic databases was conducted. Studies included patients with recurrent or residual oropharyngeal squamous cell carcinoma treated with salvage surgery. Primary outcomes were survival rates following salvage surgery. Secondary outcomes included time to recurrence, staging at time of recurrence, post-operative complications, and factors associated with mortality and recurrence. Methodological appraisal and data extraction were conducted as per Joanna Briggs Institute methodology. Eighteen articles were included. The two- and five-year survival rates of the patients were 52 per cent and 30 per cent respectively. Improvements in treatment modalities for recurrent oropharyngeal squamous cell carcinoma were associated with improvements in two-year overall survival rates, with minimal change to five-year overall survival rates. Various factors were identified as being associated with long-term overall survival, thus assisting clinicians in patient counselling and selection for salvage surgery.

Introduction To compare the results of cold-knife optical internal urethrotomy (OIU) and Holmium:YAG laser internal urethrotomy (HIU) in primary bulbar urethral strictures. Material and methods A total of 63 patients diagnosed with primary bulbar urethral stricture between August 2014 and September 2015 were assigned to the OIU (n = 29) and HIU (n = 34) groups. The demographic variables, biochemistry panels, and preoperative and postoperative uroflowmetry results including the maximum flow rate (Qmax) and mean flow rate (Qmean) values, retrograde urethrography, and diagnostic flexible urethroscopy findings were recorded prospectively. Demographic features and preoperative values were not statistically different between groups (p >0.05). Mean surgical times were 18.4 ±2.3 min for OIU and 21.9 ±3.8 min for HIU groups, which was statistically significant (p <0.05). There was no significant difference in complication rates in both groups (p = 0.618). Results Postoperative Qmax values were increased in both groups even though postoperative Qmax values were not significantly different between the two groups in the short- and long-term results at 3, 6, and 12 months (p >0.05). There was no recurrence in the first 3 months in either group. The urethral stricture recurrence rate up to month 12 was not statistically significant for the OIU group (n = 6, 20.7%) as compared to the HIU group (n = 11, 32.4%; p = 0.299). At follow-up, the SFR and IFR was 96% and 88% at 3-months, and 82% and 71% at 12-months, respectively (p <0.001). While almost three-quarters of patients were stone and infection free at 12-months, the majority of those with stones recurrence also had recurrence of their UTI. Conclusions HIU is an alternative method to OIU, and it has similar success rates in the treatment of short segment bulbar urethral strictures. PMID:29732217

WE-AB-207B-04: A Preliminary Investigation of Indicators for Treatment Outcomes of CT Guided Cervical Cancer Brachytherapy

DOE Office of Scientific and Technical Information (OSTI.GOV)

Meerschaert, R; Paul, A; Chen, W

Purpose: To identify indicators for recurrence in cervical cancer patients treated with high-dose-rate brachytherapy (HDR-BT). Methods: A total of 37 biopsy proven uterine cervical cancer patients of stage IB-IVA treated between 2011 and 2015 were included in this study. All patients were treated with 37.8–52.2Gy of external beam radiotherapy (EBRT) plus 5 × 5.0–6.5Gy of HDR-BT. Patient age, standard deviation of high-risk clinical tumor volume (HR-CTVSD) collected throughout HDR-BT, and D90 (EQD2, α/β=10Gy) of the HR-CTV were investigated as potential indicators for local/distant recurrence using ROC analysis. The optimal cutoff value was identified through the Youden index and was subsequentlymore » used to obtain a group assignment for all patients. Another two comparing groups were defined per evidence of post-EBRT tumor shrinkage based on the pre-HDR MR scan. Kaplan-Meier curves were generated for recurrence-free proportions for comparing groups where time was measured from the final HDR treatment date to the date of the final follow-up exam and compared through Cox regression. Results: Patients had a median follow-up of 12 months, where 16% had local pelvic recurrence and 16% had distant recurrence. HR-CTVSD was identified as a statistically significant indicator for recurrence (AUC=0.802, p=0.007) compared to D90 (AUC=0.655, p=0.167) and patient age (AUC=0.683, p=0.103). HR-CTVSD of 6.26cc was chosen as the optimal cutoff value, which was used as the basis for patient group assignment. Patients with HR-CTVSD>6.26cc had a hazard ratio of 3.92 (95% CI-1.37, 11.24; p=0.011) for recurrence compared to HRCTVSD≤ 6.26cc. Patients without evidence of post-EBRT tumor shrinkage compared to those with had a hazard ratio of 4.28 (95% CI-1.14, 16.15; p=0.032) for recurrence. Conclusion: HR-CTVSD was identified as an indicator for recurrence and an optimal value of 6.26cc was established in our study. In addition, patients without evidence of post-EBRT tumor shrinkage demonstrated an increased recurrence rate.« less

The aim of the study was to investigate whether patients with bipolar depression and patients with recurrent depressive disorder present with different subtypes of depressive episode as according to ICD-10. All patients who got a diagnosis of bipolar affective disorder, current episode of depression, or a diagnosis of recurrent depressive disorder, current episode of depression, in a period from 1994 to 2002 at the first outpatient treatment or at the first discharge from psychiatric hospitalization in Denmark were identified in a nationwide register. Totally, 389 patients got a diagnosis of bipolar disorder, current episode of depression, and 5.391 patients got a diagnosis of recurrent depressive disorder, current episode of depression, at first contact. Compared with patients with a diagnosis of recurrent depressive disorder, patients with bipolar disorder, current episode of depression, were significantly less often outpatients (49.4 vs. 68.0%), significantly more often got a diagnosis of severe depression (42.7 vs. 23.3%) or a diagnosis of depression with psychotic symptoms (14.9 vs. 7.2%). The rate of subsequent hospitalization was increased for patients with bipolar disorder, current episode of depression, compared with patients with a current depression as part of a recurrent depressive disorder (HR = 1.50, 95% CI = 1.20-1.86). The results consistently indicate that a depressive episode is severer and/or more often associated with psychotic symptoms when it occurs as part of a bipolar disorder than as part of a recurrent depressive disorder.

Recurrent chronic subdural hematoma (CSDH) is not rare. Some studies have demonstrated the role of dexamethasone in the medical management of chronic subdural hematoma. However, no systematic study in the treatment of recurrent CSDH has been published. The aim of our study is to evaluate the efficacy and safety of dexamethasone in patients with recurrent CSDH. We retrospectively reviewed medical records of consecutive patients from July 2010 to September 2014. A total of 27 patients with symptomatic recurrent CSDH were included in the analysis. Follow-up for each patient consisted of computed tomography or magnetic resonance imaging every 28 days from admission to the resolution of hematoma. Data were collected on hematoma volume, complications, and outcome. Among the 27 patients, 3 patients with recurrent CSDH were only treated by burr hole surgery. Of the other 24 patients who primarily underwent dexamethasone treatment, 17 (70.8%) patients were treated successfully with medical treatment, whereas 7 patients required reoperation. Complications were noted in 3 (12.5%) patients (1 hyperglycemia, 1 urinary tract infection, and 1 pneumonia). There was 1 mortality (4.2%) for massive brain infarction. Twenty-one of the 24 patients (87.5%) recovered to their previous functional levels. There was no statistical significance in Fisher text between surgery and dexamethasone regarding success, complication, and functional recovery rate. Patients with recurrent CSDH can be treated successfully and safely with the nonsurgical medical treatment of dexamethasone. By use of this method, reoperation may be avoided.

This study aimed to identify the recurrence rate and risk factors or clinical variables predictive of vascular events after mild ischemic stroke (IS). From December 2006 to September 2007, patients with acute IS with a modified Rankin Scale of 0∼1 were consecutively enrolled in this study. Variables including sex, family history of vascular disease, age, height, weight, stroke subtype, blood pressure, lipid profile, fasting glucose, HbA1c, smoking, alcohol consumption, exercise habits, waist circumference, ankle-brachial pressure index, salt intake and physical activity were assessed. The primary outcome was stroke recurrence or other vascular events such as myocardial infarction, angina pectoris, and peripheral artery disease. Survival curves were calculated by Kaplan-Meier survival analysis, and hazard ratios for recurrence were determined by univariate and multivariate Cox proportional hazards regression models. A total of 102 mild IS patients (78 men and 24 women, mean age 64 years) were successfully followed for 3 years. Of those 102 patients, 25 (24.5%) had stroke recurrence, and 4 (3.9%) had a coronary event. Among the variables studied, abnormal ankle-brachial pressure index, metabolic syndrome, stroke subtypes, salt intake and poor lifestyle management were significant independent predictors of stroke recurrence or cardiovascular events. In mild IS patients within 3 years after onset, not only pathophysiological factors but also lifestyle factors can aid in the identification of patients at high risk for recurrence.

The veins from the lower rectum drain into the systemic venous system, while those from other parts of the colon drain into the portal venous system. The aim of this study was to investigate recurrence pattern and survival according to the anatomical differences in patients with colorectal liver metastases (CRLM). From October 1994 to December 2009, synchronous CRLM patients who underwent surgery were identified from our prospectively collected database. The patients were excluded if there had been extrahepatic metastases. The patients were divided into two groups according to the location of the primary colorectal cancer: lower rectal cancer (group 1) and upper rectal or colon cancer (group 2). The recurrence patterns and survival were investigated. A total of 316 patients were included: 53 patients in group 1 and 263 patients in group 2. After a median follow-up of 37 months, the extrahepatic recurrence curve of group 1 was superior to that of group 2 (P < 0.001), although there was no difference between the hepatic recurrence curves (P = 0.93). The disease-free and overall survival curves of group 1 were inferior to those of group 2 (P = 0.004) (P < 0.001). Lower rectal cancer was a significant risk factor for extrahepatic recurrence in Cox proportional hazard model analysis (hazard ratio = 1.7, P = 0.04). The extrahepatic recurrence rate is high in lower rectal cancer patients after surgical treatment for synchronous CRLM.

Curative surgical resection (CSR) remains the most effective therapeutic intervention for patients with hepatocellular carcinoma (HCC); however, frequent post-surgical recurrence leads to high cancer related mortality. This study aimed to clarify the role of body mass index (BMI) and serum cholesterol level in predicting post-surgical outcomes in HCC patients after CSR. A total of 484 HCC patients including 213 BMIhigh and 271 BMIlow patients were included. Overall survival (OS) and recurrence-free survival (RFS) rates were examined in patients with differential BMI and serum cholesterol level. The analysis showed that significant different 1-, 3- and 5-year cumulative OS rates (P-value=0.015) and RFS rate (P-value=0.010) between BMIlow and BMIhigh patients. Further analysis in groups with differential serum cholesterol levels among BMIlow and BMIhigh patients indicated that the BMIlow/Chollow patients exhibited the significant lower cumulative OS and RFS rates in comparison with the remaining subjects (P-value=0.007 and 0.039 for OS and RFS rates, respectively). In conclusion, the coexistence of low BMI and low serum cholesterol level could serve as prognostic factors to predict post-operative outcomes in HCC patients undergoing surgical hepatectomy.

We operated on 16 sacral pressure ulcers in elderly and long-term residential patients who were immobile as a result of cerebral vascular disease. The mean age of patients was 76 years. Eight ulcers were treated with local fascial flaps and 8 by simple closure. The follow-up period was from 1 to 4 years. Recurrence and mortality rates were examined retrospectively. In the 16 patients, recurrence occurred in 37.5%, and 43.8% died without recurrence. The recurrence rate was 37.5% for local fascial flaps and 37.5% for simple closure. Overall mortality was 68.8% in the follow-up period. Because postoperative death was common, we should not only focus on reducing local pressure but also pay attention to any underlying disease. Because of this high mortality rate, the least invasive procedure possible should be used. Because the recurrence rate of simple closure was the same as for local fascial flaps, simple closure should be considered as a reconstructive method.

A number of techniques are available for the correction of gynecomastia. Nonscarring sparing methods are preferred, and the minimally invasive technique is to use liposuction for the gland and the fatty tissue exclusively. In this retrospective study we present our experience with a combination of liposuction and subsequent resection of the remaining gland. Sixty-two patients (112 breasts) were surgically treated for gynecomastia from January 1996 and September 2000. From 1996 to 1997 all patients suffering from gynecomastia grade Simon I-II were treated by the method described by Rosenberg and Stark, which is exclusively suction of the fatty and glandular tissue. In a retrospective chart study a high recurrence rate was found in these patients. Subsequently we changed our technique to liposuction of the fatty tissue followed by sharp excision of the glandular tissue through the incision made for the liposuction cannula in the submammary fold. Suction alone was not sufficient to remove the glandular tissue; the rate of recurrence after suction was 35%. When sharp resection of the glandular tissue was carried out after the liposuction the recurrence rate dropped to under 10%. In total our complication rate was 50% including minor sequelae. The most frequent complication was unacceptable scarring of the nipple-areola complex. Hypesthesia of the nipple-areola occurred in 13.4% of the patients. The combination of liposuction and resection of the glandular tissue is a minimally invasive correction that can be used in all cases of gynecomastia grade Simon I-II.

Introduction Neurosurgical trainees should achieve competency in chronic subdural haematoma (CSDH) drainage at an early stage in training. The effect of surgeon seniority on recurrence following surgical drainage of CSDH was examined. Methods All CSDH cases performed at St George’s Hospital in London between March 2009 and March 2012 were analysed. Recurrence was defined as clinical deterioration with computed tomography evidence of CSDH requiring reoperation within six months. The following risk factors were considered: seniority of primary and supervising surgeons, timing of surgery (working hours, outside working hours), patient related factors (age, antiplatelets, warfarin) and operative factors (general vs local anaesthesia, burr holes vs craniotomy, drain use). For recurrent cases, we examined the distance of the cranial opening from the thickest part of the CSDH. Results A total of 239 patients (median age: 79 years, range: 33–98 years) had 275 CSDH drainage operations. The overall recurrence rate was 13.1%. The median time between the initial procedure and reoperation was 16 days (range: 1–161 days). The only statistically significant risk factor for recurrence was antiplatelets (odds ratio: 2.62, 95% confidence interval: 1.13–6.10, p<0.05). Warfarin, grade of surgeon, timing of surgery, type of anaesthesia, type of operation and use of drains were not significant risk factors. In 26% of recurrent CSDH cases, the burr holes or craniotomy flaps were placed with borderline accuracy. Conclusions CSDH drainage is a suitable case for neurosurgical trainees to perform without increasing the chance of recurrence. PMID:26492904

BACKGROUND This study aimed to assess treatment outcomes of the cleft lift procedure and V-Y flap technique in the treatment of recurrent pilonidal sinus disease (PSD). MATERIAL AND METHODS A total of 51 patients who underwent cleft lift procedure and 43 patients who underwent fasciocutaneous V-Y flap technique were evaluated. The demographic characteristics, previous operations, duration of symptoms, perioperative complications, duration of operation and hospital stay, duration of draining of all patients, and recurrence of PSD were recorded. RESULTS The mean operation time was 35.61±5.254 min in the cleft lift group (CLG) and 57.42±7.327 min in the V-Y flap group (VYFG) (p=0.001). No wound dehiscence was found in the VYFG and 5 patients (9.8%) had wound dehiscence in the CLG (p=0.035). Draining time was 1.39±0.603 days in the CLG and 2.79±0.638 days in VYFG (p=0.001). The mean hospital stay was 1.75±0.523 days in the CLG and 3.77±1.02 days in the VYFG (p=0.001). Two patients (3.9%) in the CLG had recurrence and no recurrence was reported in the VYFG (p=0.189) in the given time interval. CONCLUSIONS Both methods in treatment of recurrent PSD can be preferred because of low complication and recurrence rates. Because no recurrence was found after the V-Y flap technique, it appears to be a preferable method despite some disadvantages.

Despite the modern advances in thyroid surgery, recurrent laryngeal nerve (rln) paralysis is still a critical problem. In order to decrease the rate of this complication, rln anatomy has been studied intensively. In our study, we aimed to recognize the relationship of rln and landmarks of the first tracheal ring. Eighty-six female and 18 male patients who were undergone total thyroidectomy were included in this study. Trachea vertical height (tvh), right recurrent laryngeal nerve height (rrh), left recurrent laryngeal nerve height (lrh), right recurrent laryngeal nerve to trachea anterior face median raphe distance (rrd), left recurrent laryngeal nerve to trachea anterior face median raphe distance (lrd), right recurrent laryngeal nerve respect to trachea ratio (rrtr), and left recurrent laryngeal nerve respect to trachea ratio (lrtr) parameters of all patients were measured and compared in males and females using independent t -test and measurements on both right and left sides were compared statistically without sex discrimination. There were no significant differences between groups in tvh, rrh, rrd, lrd, rrtr, and lrtr parameters. Lrh parameter was significantly higher in males than in females ( P <0.04). Comparison of right and left sides revealed that lrh was significantly higher than rrh ( P <0.001), lrd was significantly higher than rrd ( P <0.001), and rrtr was significantly higher than lrtr ( P <0.001). In this study, we have shown that in all cases the rln was located around the lower half of trachea vertical length and at this level left rln was located significantly deeper than the right side.

To determine the frequency and patterns of recurrent Chlamydia trachomatis infections, the most common bacterial sexually transmitted infection in young women. Cohort study using different data collection methods, including face-to-face interviews, medical record reviews, urine-based screening for C trachomatis infections, and a review of state health department reports of C trachomatis diagnoses. Ten community-based health centers that provided reproductive health care from June 1998 to September 2001. Eligibility criteria included being nulliparous, between the ages of 14 and 19 years, and human immunodeficiency virus-negative, all at the time of recruitment. This convenience sample (N = 411) was recruited by word of mouth, clinician referrals, and advertisements in the clinics. Prospective follow-up data were available for 93.9% (386/411) of the sample. The exposure of interest was prior chlamydia infection. Main Outcome Measure Diagnosis of recurrent C trachomatis infection. During the follow-up period of 23 318 person-months (mean, 4.7 years per person), 216 participants (52.6%) were diagnosed as having C trachomatis infection, and 123 participants (29.9% of the total sample and 56.9% of those with initial infections) were diagnosed as having recurrent C trachomatis infections. Of 456 C trachomatis diagnoses made during the study period, 241 (52.9%) were recurrent infections. The rate of recurrent infections was 42.1 per 1000 person-months. The median time to recurrent infection was 5.2 months. Recurrent C trachomatis infections comprise a substantial health burden among young women, possibly higher than previously recognized in this vulnerable population.

Chondrosarcoma of the rib is a rare disease. Although surgery is the only curative treatment option, rib resection with an adequate margin can be challenging and local recurrence is a frequent problem. In this study, the prognosis of primary and recurrent chondrosarcoma of the rib is reported. Retrospective analysis was performed of patients treated for chondrosarcoma of the rib between 1984 and 2014 in three major tertiary referral centers in The Netherlands. Clinical and histopathological features were analyzed for their prognostic value using Kaplan-Meier and Cox proportional hazard analysis. Endpoints were set at local recurrent disease, metastasis rate, or death. Overall, 76 patients underwent a resection for a primary chondrosarcoma, and 26 patients underwent a resection for a recurrent chondrosarcoma. Five-year overall survival in the primary group was 90%, local recurrence rate was 17%, and metastasis rate was 12%. The 5-year outcome after recurrent chondrosarcoma was lower, with an overall survival of 65%, local recurrence rate of 27%, and metastasis rate of 27%. For primary chondrosarcoma, tumor size >5 cm and a positive resection margin were correlated with worse overall survival [hazard ratio (HR) 3.28, 95% confidence interval (CI) 1.03-10.44; HR 2.92, 95% CI 1.03-8.25). A higher histological grade was correlated with a higher local recurrence and metastasis rate (HR 5.92, 95% CI 1.11-31.65; HR 6.96, 95% CI 1.15-42.60). Surgical resection of both primary and recurrent chondrosarcoma of the rib is an effective treatment strategy. The oncological outcome after surgery is worse in tumors >5 cm, in tumors with positive resection margins and grade 3 chondrosarcoma.

OBJECTIVE The object of this study was to establish recurrence rates in patients with craniopharyngioma postoperatively treated with recombinant human growth hormone (rhGH) as a basis for determining the risk of rhGH therapy in the development of recurrent tumor. METHODS The study included 739 pediatric patients with craniopharyngioma who were naïve to GH upon entering the Genentech National Cooperative Growth Study (NCGS) for treatment. Reoperation for tumor recurrence was documented as an adverse event. Cox proportional-hazards regression models were developed for time to recurrence, using age as the outcome and enrollment date as the predictor. Patients without recurrence were treated as censored. Multivariate logistic regression was used to examine the incidence of recurrence with adjustment for the amount of time at risk. RESULTS Fifty recurrences in these 739 surgically treated patients were recorded. The overall craniopharyngioma recurrence rate in the NCGS was 6.8%, with a median follow-up time of 4.3 years (range 0.7-6.4 years.). Age at the time of study enrollment was statistically significant according to both Cox (p = 0.0032) and logistic (p < 0.001) models, with patients under 9 years of age more likely to suffer recurrence (30 patients [11.8%], 0.025 recurrences/yr of observation, p = 0.0097) than those ages 9-13 years (17 patients [6.0%], 0.17 recurrences/yr of observation) and children older than 13 years (3 patients [1.5%], 0.005 recurrences/yr of observation). CONCLUSIONS Physiological doses of GH do not appear to increase the recurrence rate of craniopharyngioma after surgery in children, but long-term follow-up of GH-treated patients is required to establish a true natural history in the GH treatment era.

Persistent changes in serotonergic and hypothalamic pituitary adrenal (HPA) axis functioning are implicated in recurrent types of major depressive disorder (MDD). Systemic tryptophan levels, which influence the rate of serotonin synthesis, are regulated by glucocorticoids produced along the HPA axis. We investigated tryptophan metabolism and its association with HPA axis functioning in single episode MDD, recurrent MDD and non-depressed individuals. We included depressed individuals (n = 1320) and controls (n = 406) from the Netherlands Study of Depression and Anxiety (NESDA). The kynurenine to tryptophan ratio (kyn/trp ratio) was established using serum kynurenine and tryptophan levels. Several HPA axis parameters were calculated using salivary cortisol samples. We adjusted the regression analyses for a wide range of potential confounders and differentiated between single episode MDD, recurrent MDD and control. Tryptophan, kynurenine and the kyn/trp ratio did not differ between controls and depressed individuals. Increased evening cortisol levels were associated with a decreased kyn/trp ratio in the total sample (Crude: β = -.102, p < .001; Adjusted: β = -.083, p < .001). This association was found to be restricted to recurrently depressed individuals (Crude: β = -.196, p < .001; Adjusted: β = -.145, p = .001). Antidepressant treatment did not affect this association. Our results suggest that an imbalance between HPA axis function and tryptophan metabolism could be involved in recurrent depression. Copyright © 2017 Elsevier B.V. All rights reserved.

In most Asian countries, stroke is one of the major causes of mortality. A stroke event is life-changing for stroke survivors, which results in either mortality or disability. Therefore, this study comprehensively focuses on prevalence, risk factors, and secondary prevention for stroke recurrence identified in South, East, and Southeast Asian countries. This scoping review uses the methodological framework of Arksey and O'Malley. A comprehensive search of academic journals (English) on this topic published from 2007 to 2017 was conducted. A total of 22 studies were selected from 585 studies screened from the electronic databases. First-year stroke recurrence rates are in the range of 2.2% to 25.4%. Besides that, modifiable risk factors are significantly associated with pathophysiological factors (hypertension, ankle-brachial pressure index, atherogenic dyslipidaemia, diabetes mellitus, metabolic syndrome, and atrial fibrillation) and lifestyle factors (obesity, smoking, physical inactivity, and high salt intake). Furthermore, age, previous history of cerebrovascular events, and stroke subtype are also significant influence risk factors for recurrence. A strategic secondary prevention method for recurrent stroke is health education along with managing risk factors through a combination of appropriate lifestyle intervention and pharmacological therapy. To prevent recurrent stroke, health intervention should be geared towards changing lifestyle to embody a healthier approach to life. This is of great importance to public health and stroke survivors' quality of life.

The clinical efficacy of catheter ablation (CA) for paroxysmal atrial fibrillation (PAF) in patients with sick sinus syndrome (SSS) and the mechanism and predictors of recurrence are not yet completely elucidated. Of 963 consecutive patients who underwent PAF ablation during the study period, a total of 108 patients with SSS (SSS group) and 108 matched controls without SSS (non-SSS group) were followed up. During the follow-up period (mean, 32.8±17.5 months), the SSS group had significantly higher AF recurrence rate since the last procedure than the non-SSS group (26.9% vs. 12.0%; P=0.02). The SSS group had significantly higher prevalence of non-pulmonary vein (non-PV) foci than the non-SSS group (25.9% vs. 13.9%; P=0.027). On multivariate analysis congestive heart failure (HR, 13.7; 95% CI: 1.57-119; P=0.02) and non-PV foci (HR, 5.75; 95% CI: 1.69-19.6; P=0.005) were independent predictors of recurrence following CA in the SSS group. In the SSS group, 88 patients had bradycardia-tachycardia syndrome without prior permanent pacemaker implantation. Of these, 6 required pacemaker implantation because of AF and sinus pause recurrence. Patients with SSS are at higher risk of AF recurrence after CA. Non-PV foci are associated with AF recurrence following PAF with SSS.

The goal was to determine recurrent or second primary status for late stomal malignancies, 16 and 17 years post-total laryngectomy in two laryngeal squamous cell carcinoma (LSCC) patients, based on DNA methylation signatures and HPV typing. Adopting a literature review based definition of late stomal recurrences as new primaries at the site of the stoma or neopharynx occurring >5 years after total laryngectomy, we employed a multi-gene candidate approach to examine promoter methylation in 24 tumor suppressor genes and PCR-based assays for HPV status offered additional insights into whether the late stomal tumors post-total laryngectomy were related or not. The primary tumor for Patient 1 was negative for HPV but had aberrant hypermethylation of APC, MLH1 and BRCA1. The stomal biopsy 17-years later showed presence of HPV-16 without any methylated genes. In Patient 2, HPV-11 and promoter methylation of APC identified in the primary tumor was also observed in the stomal malignancy 16 years post-total laryngectomy. Additional information provided by molecular typing for HPV and methylation markers underscored Patient 1's and 2's late stomal presentation as most likely a second primary and recurrence, respectively. DNA methylation markers are particularly advantageous because DNA methylation is an early event in tumorigenesis, and the epigenetic modification, 5-methylcytosine, is a stable marker. Molecular marks to discern genetic heterogeneity or relatedness of stomal malignancies several years post-total laryngectomy can provide clues to their status as either second primaries or likely recurrences. Our results support the hypothesis that a subset of stomal recurrences after total laryngectomy represents second primary tumors.

Custom-made footwear is the treatment of choice to prevent foot ulcer recurrence in diabetes. This footwear primarily aims to offload plantar regions at high ulcer risk. However, ulcer recurrence rates are high. We assessed the effect of offloading-improved custom-made footwear and the role of footwear adherence on plantar foot ulcer recurrence. We randomly assigned 171 neuropathic diabetic patients with a recently healed plantar foot ulcer to custom-made footwear with improved and subsequently preserved offloading (∼20% peak pressure relief by modifying the footwear) or to usual care (i.e., nonimproved custom-made footwear). Primary outcome was plantar foot ulcer recurrence in 18 months. Secondary outcome was ulcer recurrence in patients with an objectively measured adherence of ≥80% of steps taken. On the basis of intention-to-treat, 33 of 85 patients (38.8%) with improved footwear and 38 of 86 patients (44.2%) with usual care had a recurrent ulcer (relative risk -11%, odds ratio 0.80 [95% CI 0.44-1.47], P = 0.48). Ulcer-free survival curves were not significantly different between groups (P = 0.40). In the 79 patients (46% of total group) with high adherence, 9 of 35 (25.7%) with improved footwear and 21 of 44 (47.8%) with usual care had a recurrent ulcer (relative risk -46%, odds ratio 0.38 [0.15-0.99], P = 0.045). Offloading-improved custom-made footwear does not significantly reduce the incidence of plantar foot ulcer recurrence in diabetes compared with custom-made footwear that does not undergo such improvement, unless it is worn as recommended.

Preauricular sinuses are benign congenital malformations of preauricular soft tissues. Complete excision using either sinectomy or supra-auricular approach is advised to prevent recurrence. Reported recurrence varies between 0 and 42%. We evaluated which surgical technique resulted in lowest complication and recurrence rates. PubMed, Embase, Scopus, Web of Science. Two authors appraised studies on directness of evidence and risk of bias. Original data were extracted and pooled when I(2) was smaller than 50%. Results are reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Fourteen high directness of evidence studies were included. Reported complication rates were similar: sinectomy [0-31.4%] and supra-auricular approach (SAA) [0-18.2%]. Pooled recurrence rates showed that sinectomy resulted in significantly (P = .04) more recurrence 5.5% (95% confidence interval [CI] 3.6-8.3%) than SAA 2.2% (95% CI 0.7-7.0). Sinectomy using the microscope resulted in the lowest sinectomy recurrence rates (1.9%). SAA in combination with a Penrose drain resulted in 0% recurrence in revision cases. Drain use resulted in the lowest SAA recurrence rates; however, drain application was not advised due to higher complication rates (frequent wound infection [P = .003] and more [P = .002] and longer [P = .001] compression dressing use). SAA could be the preferable technique for preauricular sinus removal. If despite evidence, sinectomy is elected over SAA, microscope use can further decrease recurrence rates comparable to SAA levels. Level of included evidence (Ib-IV) indicates the need for a prospective study comparing surgical outcomes between techniques.

Optimal management of the cervix at the time of hysterectomy and sacrocolpopexy for primary uterovaginal prolapse is unknown. Our hypothesis was that recurrent prolapse at 1 year would be more likely after a supracervical robotic hysterectomy (SRH) compared with a total robotic hysterectomy (TRH) at the time of robotic sacrocolpopexy (RSCP) for uterovaginal prolapse. This was a retrospective cohort analysis of 83 women who underwent hysterectomy with RSCP over a 24-month period (40 with TRH and 43 with SRH). At 1 year post-procedure, subjects completed validated questionnaires regarding pelvic floor symptoms, sexual function, and global satisfaction, and underwent a pelvic examination to identify mesh exposure and evaluate pelvic floor support. Demographics of the two groups were similar, except for a higher mean body mass index in the TRH group (31.9 TRH vs 25.8 SRH kg/m(2), p < 0.001). The rate of recurrent prolapse ≥ stage II was higher for women who underwent SRH compared with TRH (41.9 % vs 20.0 %, p = 0.03; OR 2.8, 95 % CI, 1.07-7.7). However, when this was analyzed as recurrence ≥ hymen, there was no difference between groups (12.5 % TRH vs 18.6 % SRH, p = 0.45). Likewise, there was no difference between groups when a composite measure of success was used (30 out of 40 [75 %] TRH vs 29 out of 43 [67.4 %] SRH, p = 0.45). Women who underwent an SRH were 2.8 times more likely to have a recurrent prolapse, ≥ stage II, at 1 year, compared with those who underwent a TRH, but when composite assessment scores were used there was no difference between the groups.

Objective: A retrospective study was designed to evaluate the results of surgical treatment and follow-up data in thyroid cancer patients less than 15 years old at the time of surgery. Summary Background Data: Pediatric thyroid carcinomas have a high rate of lymph nodal and distant metastases. Risk factors for recurrences and postoperative morbidity have not been assessed yet in a representative series. Methods: The group included 740 pediatric patients with thyroid cancer. Total thyroidectomy was performed in 426 (57.6%), lobectomy in 248 (33.5%), subtotal thyroidectomy in 58 (7.8%) cases, and 8 patients (1.1%) underwent partial lobectomy. Results: The mean follow-up period was 115.8 months (range, 1.5–236.4 months). Recurrence was diagnosed in 204 cases (27.6%), including 73 local relapses (9.9%), 90 distant metastases (12.2%), and a combination of local and distant recurrences in 41 (5.5%) patients. Multivariate statistical assessment revealed the following independent parameters significantly associated with the risk of recurrent nodal disease: a young age at diagnosis, multifocal carcinomas, N1 status, and lack of neck lymph node dissection. For lung metastases, the significant risk factors were female gender, young age at diagnosis, and presence of symptoms. The observed 5- and 10-year survival for the entire group was 99.5% and 98.8%, respectively. Postoperative hypoparathyroidism was significantly associated with multifocal tumors, central compartment removal, and ipsilateral dissection. Conclusions: Total thyroidectomy followed by radioiodine therapy is an optimal treatment strategy that makes it possible to achieve a cure in a vast majority of pediatric patients with differentiated thyroid carcinomas. Risk of recurrence is strongly associated with tumor stage, extent of surgery, the young patient's age, and presence of symptoms at diagnosis. PMID:16552205

The safety of regional hyperthermia has been tested in locally advanced rectal cancer. The aim of this study was to assess the effects of shorter distal margins on local control and survival in rectal cancer patients who were treated with preoperative hyperthermochemoradiation therapy (HCRT) and underwent rectal resection by using the total mesorectal excision (TME) method. Ninety-three patients with rectal adenocarcinoma who received neoadjuvant HCRT (total radiation: 50 Gy) were included in this study. Surgery was performed 8 weeks after HCRT, and each resected specimen was evaluated histologically. Length of distal surgical margins, status of circumferential margins, pathological response, and tumor node metastasis stage were examined for their effects on recurrence and survival. Fifty-eight (62.4%) patients had tumor regression, and 20 (21.5%) had a pathological complete response. Distal margin length ranged from 1 to 55 mm (median, 21 mm) and did not correlate with local recurrence (p=0.57) or survival (p=0.75) by univariate analysis. Kaplan-Meier estimates of recurrence-free survival and local recurrence for the <10 mm versus ≥10 mm groups were not significantly different. Positive circumferential margins and failure of tumors to respond were unfavorable factors in survival. Distal resection margins that are shorter than 10 mm but are not positive appear to be equivalent to longer margins in patients who undergo HCRT followed by rectal resection with TME. To improve the down-staging rate, additional studies are needed.

Recurrence of giant cell tumor of bone (GCTB) in the soft tissue is rarely seen in the clinical practice. This study aims to determine the prevalence of soft tissue recurrence of GCTB, and to characterize its radiographic features. A total of 291 patients treated by intralesional curettage for histologically diagnosed GCTB were reviewed. 6 patients were identified to have the recurrence of GCTB in the soft tissue, all of whom had undergone marginal resection of the lesion. Based on the x-ray, CT and MRI imaging, the radiographic features of soft tissue recurrence were classified into 3 types. Type I was defined as soft tissue recurrence with peripheral ossification, type II was defined as soft tissue recurrence with central ossification, and type III was defined as pure soft tissue recurrence without ossification. Demographic data including period of recurrence and follow-up duration after the second surgery were recorded for these 6 patients. Musculoskeletal Tumor Society (MSTS) scoring system was used to evaluate functional outcomes. The overall recurrence rate was 2.1% (6/291). The mean interval between initial surgery and recurrence was 11.3 ± 4.1 months (range, 5-17). The recurrence lesions were located in the thigh of 2 patients, in the forearm of 2 patients and in the leg of the other 2 patients. According to the classification system mentioned above, 2 patients were classified with type I, 1 as type II and 3 as type III. After the marginal excision surgery, all patients were consistently followed up for a mean period of 13.4 ± 5.3 months (range, 6-19), with no recurrence observed at the final visit. All the patients were satisfied with the surgical outcome. According to the MSTS scale, the mean postoperative functional score was 28.0 ± 1.2 (range, 26-29). The classification of soft tissue recurrence of GCTB may be helpful for the surgeon to select the appropriate imaging procedure to detect the recurrence. In addition, the marginal resection can produce a favorable outcome for the patients.

To evaluate and compare medium-term clinical outcomes and recurrence rates in the laparoscopic surgical management of bowel endometriosis comparing 3 different surgical techniques (shaving, discoid, and segmental resection). Retrospective study (Canadian Task Force classification II-2). Endometriosis tertiary referral center. A retrospective cohort of 106 patients with histological confirmation of bowel endometriosis undergoing laparoscopic surgical treatment between January 1, 2010, and September 1, 2012. Assessment of laparoscopic bowel shaving, discoid or segmental resection for the treatment of painful symptoms related to deep endometriosis (DE) involving the bowel with 24 months of follow-up. A total of 92 patients were included in the study and were divided into 3 groups according to the surgical procedure performed (shaving, n = 47; discoid resection, n = 15; segmental resection, n = 30). All symptoms improved significantly in the immediate postoperative follow-up, with significant reduction in all visual analog scale scores for pain. Compared with the discoid resection and segmental resection groups, the shaving group had a significantly higher rate of medium-term recurrence of dysmenorrhea and dyspareunia. Furthermore, the shaving group had a higher rate of reintervention for recurrent DE lesions compared with the segmental resection group (27.6% vs 6.6%; relative risk [RR], 4.14; 95% confidence interval [CI], 1.0-17.1). Postoperative complication rates were similar across all 3 groups with a rate of major complications of 4.2% in the shaving group, 6.6% in the discoid resection group, and 6.6% in the segmental resection group. According to our data, the patients with a nodule >3 cm had an RR of 2.5 (95% CI, 1.66-3.99) of requiring bowel resection. All 3 treatment modalities are effective in terms of immediate symptom relief with acceptable complication rates. However, significantly higher rates of symptom recurrence and reintervention were noted in the shaving group, whereas segmental resection is more likely to be indicated in cases of large nodules.

AIM To estimate Helicobacter pylori (H. pylori) recurrence rate in Latin America, a region with a significant H. pylori prevalence and gastric cancer burden. METHODS PubMed, LILACS, SciELO, Cochrane databases and abstracts from relevant meetings were reviewed. Information collected included: Participants’ characteristics, recruitment strategy, diagnostic modality, treatment arms, follow-up and recurrence rates. Recurrence was calculated using 100-patients-year rates, and data were pooled using a random effects model. The I2 statistic assessed between study heterogeneity. Meta-regression analyses evaluated for effect modifying variables. RESULTS Literature search yielded 163 articles. Twelve studies involving 4848 patients from 9 countries met inclusion criteria. Four hundred and thirty-two reinfections were recorded in 5487 person-years of follow-up. Pooled analysis showed a recurrence rate of 7.9 cases per 100 person-years (95%CI: 5.3-10.5). Meta-regression revealed that neither the antibiotic schema, a second antibiotic course, nor the diagnostic modality had an impact on the observed risk of recurrence. The recurrence rate in the first year after treatment, predominantly recrudescence, was 11.2 (6.1-16.4) per 100 patient years. Recurrence in subsequent years, was only 6.2 (3.8-8.7). CONCLUSION H. pylori recurrence rates in Latin America are significant, and with geographic variability, yet are acceptable based upon the current literature for consideration of large scale intervention trials. Further research in Latin America is warranted to evaluate the efficacy, cost-effectiveness, and potential adverse outcomes of proposed eradication programs. PMID:28451066

Purpose: To evaluate treatment effects, complications, and outcome of percutaneous stereotactic radiofrequency ablation (SRFA) of intrahepatic cholangiocarcinoma (ICC). Patients and Methods: Eleven consecutive patients (nine men and two women) with a total of 36 inoperable ICCs (18 initial lesions, 16 lesions newly detected during follow-up, and two local recurrences) underwent SRFA between December 2004 and June 2010. Two different radiofrequency ablation (RFA) devices with internally cooled electrodes were used. Tumor diameters ranged from 0.5 to 10 cm (median 3.0 cm). A total of 23 SRFA sessions were performed. The efficacy of SRFA was evaluated by contrast-enhanced computed tomography or magneticmore » resonance imaging 1 month after treatment and then every 3 months. Results: Primary technical effectiveness rate was 92%. Further follow-up every 3 months revealed three local recurrences (8%), two of which were successfully retreated, resulting in a secondary technical effectiveness rate of 98%. After a total of 23 RFA sessions, three major complications occurred (13%) that could be managed interventionally. Mean follow-up time was 35 months (range 12-81 months). One- and 3-year overall survival rates were 91 and 71%, respectively. The median overall survival was 60 months (according to the life table method). Eight (73%) of 11 patients were still alive at the end of follow-up. Conclusion: SRFA is effective in the treatment of unresectable ICC even if the tumor is large and located close to major vessels. SRFA shows a survival benefit compared to other palliative treatment options and may also be considered as the first-line local treatment of ICCs in selected patients.« less

2013-01-01

Background and Objectives: Recent studies have supported minimally invasive techniques as a viable alternative to open surgery in the treatment of gastric cancer. The goal of this study is to review our institution's experience with totally laparoscopic gastrectomy for the treatment of both early- and advanced-stage gastric cancer. Methods: A retrospective study was conducted to examine the short-term outcomes of laparoscopic gastrectomy performed at Monmouth Medical Center between May 2003 and June 2012. We reviewed postoperative complications, surgical margins, number of resected lymph nodes, estimated blood loss, length of stay, narcotic use, and recurrence rate. Results: Forty patients were included in the study. There were 21 cases of adenocarcinoma, 15 cases of gastrointestinal stromal tumor, 2 cases of carcinoid, 1 case of small cell neuroendocrine tumor, and 1 case of squamous cell carcinoma. The mean operative time was 220 minutes (range, 67–450 minutes). The median length of stay was 6 days (range, 1–37 days). The mean number of harvested lymph nodes was 11. Early postoperative complications occurred in 7 patients and included anastomotic stricture, wound infection, intra-abdominal abscess, bowel obstruction, and esophageal pneumatosis. There were two deaths. The Kaplan-Meier 5-year overall and recurrence-free survival rate for all cases of adenocarcinoma was 63.2%. Conclusions: Totally laparoscopic gastrectomy is a reasonable option for the treatment of gastric malignancy, with early data showing acceptable survival rates and perioperative outcomes. Large-scale randomized trials are still needed to confirm oncologic equivalency to open gastrectomy in patients with advanced disease. PMID:24398204

To evaluate the efficacy and safety of the laparoscopic approaches for parastomal hernia repair reported in the literature. A systematic review of PubMed and MEDLINE databases was conducted using various combination of the following keywords: stoma repair, laparoscopic, parastomal, and hernia. Case reports, studies with less than 5 patients, and articles not written in English were excluded. Eligible studies were further scrutinized with the 2011 levels of evidence from the Oxford Centre for Evidence-Based Medicine. Two authors reviewed and analyzed each study. If there was any discrepancy between scores, the study in question was referred to another author. A meta -analysis was performed using both random and fixed-effect models. Publication bias was evaluated using Begg's funnel plot and Egger's regression test. The primary outcome analyzed was recurrence of parastomal hernia. Secondary outcomes were mesh infection, surgical site infection, obstruction requiring reoperation, death, and other complications. Studies were grouped by operative technique where indicated. Except for recurrence, most postoperative morbidities were reported for the overall cohort and not by approach so they were analyzed across approach. Fifteen articles with a total of 469 patients were deemed eligible for review. Most postoperative morbidities were reported for the overall cohort, and not by approach. The overall postoperative morbidity rate was 1.8% (95%CI: 0.8-3.2), and there was no difference between techniques. The most common postoperative complication was surgical site infection, which was seen in 3.8% (95%CI: 2.3-5.7). Infected mesh was observed in 1.7% (95%CI: 0.7-3.1), and obstruction requiring reoperation also occurred in 1.7% (95%CI: 0.7-3.0). Other complications such as ileus, pneumonia, or urinary tract infection were noted in 16.6% (95%CI: 11.9-22.1). Eighty-one recurrences were reported overall for a recurrence rate of 17.4% (95%CI: 9.5-26.9). The recurrence rate was 10.2% (95%CI: 3.9-19.0) for the modified laparoscopic Sugarbaker approach, whereas the recurrence rate was 27.9% (95%CI: 12.3-46.9) for the keyhole approach. There were no intraoperative mortalities reported and six mortalities during the postoperative course. Laparoscopic intraperitoneal mesh repair is safe and effective for treating parastomal hernia. A modified Sugarbaker approach appears to provide the best outcomes.

Positron emission tomography/computed tomography (PET/CT) is commonly used for nodal staging in locally advanced cervical cancer; however the false negative rate for para-aortic disease are 20% to 25% in PET-positive pelvic nodal disease. Unless surgically staged, pelvis-only treatment may undertreat para-aortic disease. We have treated patients with PET-positive nodes with extended field intensity modulated radiation therapy (IMRT) to address the para-aortic region prophylactically with concomitant boost to involved nodes. The purpose of this study was to assess regional control rates and recurrence patterns. Sixty-one patients with cervical cancer (stage IBI-IVA) diagnosed from 2003 to 2012 with PET-avid pelvic nodes treated with extended field IMRT (45 Gy in 25 fractions with concomitant boost to involved nodes to a median of 55 Gy in 25 fractions) with concurrent cisplatin and brachytherapy were retrospectively analyzed. The nodal location was pelvis-only in 41 patients (67%) and pelvis + para-aortic in 20 patients (33%). There were a total of 179 nodes, with a median number of positive nodes of 2 (range, 1-16 nodes) per patient and a median nodal size of 1.8 cm (range, 0.7-4.5 cm). Response was assessed by PET/CT at 12 to 16 weeks. Complete clinical and imaging response at the first follow-up visit was seen in 77% of patients. At a mean follow-up time of 29 months (range, 3-116 months), 8 patients experienced recurrence. The sites of persistent/recurrent disease were as follows: cervix 10 (16.3%), regional nodes 3 (4.9%), and distant 14 (23%). The rate of para-aortic failure in patients with pelvic-only nodes was 2.5%. There were no significant differences in recurrence patterns by the number/location of nodes, largest node size, or maximum node standardized uptake value. The rate of late grade 3+ adverse events was 4%. Extended field IMRT was well tolerated and resulted in low regional recurrence in node-positive cervical cancer. The dose of 55 Gy in 25 fractions was effective in eradicating disease in involved nodes, with acceptable late adverse events. Distant metastasis is the predominant mode of failure, and the OUTBACK trial may challenge the presented paradigms. Copyright © 2014 Elsevier Inc. All rights reserved.

Background For recipients of liver transplants for hepatocellular carcinoma (HCC), HCC recurrence after transplantation remains a major concern. Sirolimus, an immunosuppressant with anti-carcinogenic properties, may reduce HCC recurrence and improve survival. Methods The U.S. Scientific Registry of Transplant Recipients was linked to pharmacy claims. For liver recipients transplanted for HCC, Cox regression was used to estimate associations of early sirolimus use with recurrence, cancer-specific mortality, and all-cause mortality adjusting for recipient ethnicity, calendar year of transplant, total tumor volume, alpha-fetoprotein, transplant center size, use of IL-2 induction therapy, and allocated and calculated model for end-stage liver disease score. We performed stratified analyses among recipients who met Milan criteria, among those without renal failure, among those with deceased liver donors, by age at transplantation, and by tumor size. Results Among the 3,936 included HCC liver transplants, 234 (6%) were sirolimus users. In total, there were 242 recurrences and 879 deaths, including 261 cancer-related deaths. All-cause mortality was similar in sirolimus users and non-users (adjusted hazard ratio [HR] =1.01, 95%CI=0.73–1.39). HCC recurrence and cancer-specific mortality rates appeared lower in sirolimus users, but associations were not statistically significant (recurrence HR=0.86, 95%CI=0.45–1.65; cancer-specific mortality HR=0.80, 95%CI=0.43–1.50). Among recipients >55 years old, associations were suggestive of better outcomes for sirolimus users (all-cause mortality HR=0.62, 95%CI=0.38–1.01; recurrence HR=0.52, 95%CI=0.19–1.44; cancer-specific mortality HR=0.34, 95%CI=0.11–1.09), while among recipients ≤55 years old, sirolimus users had worse outcomes (all-cause mortality HR=1.76, 95%CI=1.12–2.75; recurrence HR=1.49, 95%CI=0.62–3.61; cancer-specific mortality HR=1.54, 95%CI=0.71–3.32). Conclusions Among HCC liver recipients overall, sirolimus did not appear beneficial in reducing all-cause mortality. However, there were suggestions of reductions in recurrence and cancer-specific mortality, and effects appeared to be modified by age at transplantation. PMID:26784951

Reverse dipper, blood pressure (BP) rises during night-time, is a risk factor of increased cardiovascular events in hypertensive patients. However, we have little information whether reverse dipper in acute stage of cerebral infarction (CI) affects on the recurrence and mortality. We studied to assess the relationship between reverse dipper and adverse clinical outcomes in the acute stage of CI. We screened and enrolled consecutive patients with acute CI with ambulatory blood pressure monitoring (ABPM) within 2 weeks after admission from August 2001 to July 2005. According to systolic blood pressure (SBP) dropping pattern during night-time compared with daytime, we classified into extreme dipper (≥20%), dipper (≥10%, <20%), nondipper (≥0%, <10%), and reverse dipper (BP rises during night-time). We analyzed 426 patients (72 ± 13 years old, 255 men) and checked recurrence of CI or all-cause mortality for further 7.6 ± 3.1 years for checking of recurrence or all-cause mortality. Of 426 patients, 202 patients were nondippers (47%), 134 were reverse dippers (32%), 80 were dippers (19%), and 10 were extreme dippers (2%). During the follow-up period, 89 patients (21%) had recurrence of CI. After multivariate analysis, daytime SBP (hazard ratio = 1.014, P = .018) was the significant predictor of recurrence. There were 141 deaths (33%) in our study cohort. Multivariate analysis showed that age (hazard ratio = 1.106, P < .001), nocturnal mean heart rate (hazard ratio = 1.023, P = .004), and reverse dipper (hazard ratio = 1. 676, P = .007) were statistically significant. Reverse dipper and high night-time heart rate in the acute stage of CI were associated with total mortality during long-term follow-up. These findings suggest the clinical utility of ABPM in acute stage of CI. Copyright © 2014 National Stroke Association. Published by Elsevier Inc. All rights reserved.

Background Despite the presence of a plethora of publications on the prevention of postoperative nausea and vomiting (PONV) only little is known how to treat established symptoms. Besides the high effort of performing these efficacy trials (much more patients must give their consent than are actually included in a study) and ethical concerns, little is known about the rate of re-occurring PONV/vomiting after placebo. As a consequence investigators will have difficulties defining a clinically relevant effect for the new treatment which is crucial for any planning. A quantitative systematic review was performed in order to provide more reliable estimates of the incidence of re-occurring PONV/vomiting after placebo and to help investigators defining a clinically relevant treatment effect. Methods A systematic search of the literature was performed using an extended search strategy of a previous review. Data on the recurrence of PONV (any nausea or emetic symptom) and vomiting (retching or vomiting) was extracted from published reports treating PONV with placebo and unpublished results from two observational trials where no treatment was given. A nonlinear random effects model was used to calculate estimates of the recurrence of symptoms and their 95%-confidence intervals (95%-CI). Results A total of 29 trials (including the unpublished data) were eligible for the calculations. Depending on the length of observation after administering placebo or no treatment the recurrence rate of PONV was between 65% (95%-CI: 53%...75%) and 84% (95%-CI: 73%...91%) and that of vomiting was between 65% (95%-CI: 44%...81%) and 78% (95%-CI: 59%...90%). Conclusion Almost all trials showed a considerable and consistently high rate of recurrence of emetic symptoms after placebo highlighting the need for a consequent antiemetic treatment. Future (placebo) controlled efficacy trials may use the presented empirical estimates for defining clinically relevant effects and for statistical power considerations. PMID:17166262

Defining the learning curve in laparoscopic paraesophageal hernia repair: a CUSUM analysis.

There are numerous reports in the literature documenting high recurrence rates after laparoscopic paraesophageal hernia repair. The purpose of this study was to determine the learning curve for this procedure using the Cumulative Summation (CUSUM) technique. Forty-six consecutive patients with paraesophageal hernia were evaluated prospectively after laparoscopic paraesophageal hernia repair. Upper GI series was performed 3 months postoperatively to look for recurrence. Patients were stratified based on the surgeon's early (first 20 cases) and late experience (>20 cases). The CUSUM method was then used to further analyze the learning curve. Nine patients (21%) had anatomic recurrence. There was a trend toward a higher recurrence rate during the first 20 cases, although this did not achieve statistical significance (33% vs. 13%, p = 0.10). However, using a CUSUM analysis to plot the learning curve, we found that the recurrence rate diminishes after 18 cases and reaches an acceptable rate after 26 cases. Surgeon experience is an important predictor of recurrence after laparoscopic paraesophageal hernia repair. CUSUM analysis revealed there is a significant learning curve to become proficient at this procedure, with approximately 20 cases required before a consistent decrease in hernia recurrence rate is observed.

Evaluation of the entire surgical margin results in high rates of complete excision, low local recurrence rates, and maximal tissue conservation. Although well recognized for melanoma of the head and neck, few studies have focused exclusively on the trunk and proximal extremities. We sought to evaluate the efficacy of Mohs micrographic surgery for melanoma in situ (MIS) of the trunk and proximal extremities, and determine adequate excision margins for MIS when total margin evaluation is not used. Long-term outcomes in 882 cases of MIS treated with Mohs micrographic surgery were analyzed and compared with historical controls. Rates of complete excision were determined for increasing surgical margin intervals. One local recurrence occurred in our cohort (0.1%). Only 83% of MIS were excised with a 6-mm margin. Margins of 9 mm were needed to excise 97% of MIS, statistically equivalent to thin melanomas. We used a nonrandomized, single-institution, retrospective design. Mohs micrographic surgery may cure the 17% of MIS that exceed traditional excision margins of 5 mm and is a valuable option for these patients. Surgical margins of at least 0.9 cm should be considered for MIS of the trunk and extremities when total margin evaluation is not used. Copyright © 2016 American Academy of Dermatology, Inc.

[Urethral stricture rate after prostate cancer radiotherapy : Five-year data of a certified prostate cancer center].

2017-03-01

A urethral stricture is a scar of the urethral epithelium which can cause obstructive voiding dysfunction with consequential damage of the upper urinary tract. Almost 45% of all strictures are iatrogenic; they develop in 2-9% of patients after radical prostatectomy, but can also occur after prostate cancer radiotherapy. This study provides 5‑year data of a certified prostate cancer center (PKZ) in terms of urethral strictures. Between 01/2008 and 12/2012 a total of 519 men were irradiated for prostate cancer (LDR and HDR brachytherapy as well as external beam radiation). The entire cohort was followed-up prospectively according to a standardized protocol (by type of irradiation). Short segment urethral strictures were treated by urethrotomy, recurrent and long segment stenosis with buccal mucosa urethroplasty. A total of 18 of 519 (3.4%) patients developed a urethral stricture post-therapeutically, which recurred in 66% of cases after the first operative treatment. The largest risk for developing a urethral stricture is attributed to the HDR brachytherapy (8.9%). Urethral strictures after prostate cancer radiotherapy should be diagnosed and treated in time for long-term preservation of renal function. The rate of radiogenic urethral strictures (3.4%) is equivalent to those after radical prostatectomy. Due to a high rate of recurrences, urethrotomy has a limited importance after irradiation.

2012-10-01

To call attention to the wide variety of definitions for recurrence that have been employed in studies of different invasive procedures for the treatment of Dupuytren contracture and how this important limitation has contributed to the wide range of reported results. This study reviewed definitions and rates of contracture correction and recurrence in patients undergoing invasive treatment of Dupuytren contracture. A literature search was carried out in January 2011 using the terms "Dupuytren" AND ("fasciectomy" OR "fasciotomy" OR "dermofasciectomy" OR "aponeurotomy" OR "aponeurectomy") and limited to studies in English. The search returned 218 studies, of which 21 had definitions, quantitative results for contracture correction and recurrence, and a sample size of at least 20 patients. Definitions for correction of contracture and recurrence varied greatly among articles and were almost always qualitative. Percentages of patients who achieved correction of contracture (ie, responder rate) when evaluated at various times after completion of surgery ranged from 15% to 96% for fasciectomy/aponeurectomy. Responder rates were not reported for fasciotomy/aponeurotomy. Recurrence rates ranged from 12% to 73% for patients treated with fasciectomy/aponeurectomy and from 33% to 100% for fasciotomy/aponeurotomy. Review of these reports underscored the difficulty involved in comparing correction of contracture and recurrence rates for different surgical interventions because of differences in definition and duration of follow-up. Clearly defined objective definitions for correction of contracture and for recurrence are needed for more meaningful comparisons of results achieved with different surgical interventions. Recurrence after surgical intervention for Dupuytren contracture is common. This study, which evaluated reported rates of recurrence following surgical treatment of Dupuytren contracture, provides clinicians with practical information regarding expected long-term outcomes of surgical treatment choices.

Repair of giant paraesophageal hernia (PEH) is associated with a favorably high rate of symptom improvement; however, rates of recurrence by objective measures remain high. Herein we analyze our experience with laparoscopic giant PEH repair to determine what factors if any can predict anatomic recurrence. We prospectively collected data on PEH characteristics, variations in operative techniques, and surgeon factors for 595 patients undergoing laparoscopic PEH repair from 2008 to 2015. Upper GI study was performed at 6 months postoperatively and selectively thereafter-any supra-diaphragmatic stomach was considered hiatal hernia recurrence. Exclusion criteria included revisional operation (22.4%), size <5 cm (17.6%), inadequate follow-up (17.8%), and confounding concurrent operations (6.9%). Inclusion criteria were met by 202 patients (31% male, median age 71 years, and median BMI 28.7). At a median follow-up of 6 months (IQR 6-12), overall anatomic recurrence rate was 34.2%. Symptom recurrence rate was 9.9% and revisional operation was required in ten patients (4.9%). Neither patient demographics nor PEH characteristics (size, presence of Cameron erosions, esophagitis, or Barrett's) correlated with anatomic recurrence. Technical factors at operation (mobilized intra-abdominal length of esophagus, Collis gastroplasty, number of anterior/posterior stitches, use of crural buttress, use of pledgeted or mattress sutures, or gastrostomy) were also not correlated with recurrence. Regarding surgeon factors, annual volume of fewer than ten cases per year was associated with increased risk of anatomic failure (54 vs 33%, P = 0.02). Multivariate analysis identified surgeon experience (<10 cases per year) as an independent factor associated with early hiatal hernia recurrence (OR 3.7, 95% CI 1.34-10.9). Laparoscopic repair of giant PEH is associated with high anatomic recurrence rate but excellent symptom control. PEH characteristics and technical operative variables do not appear to significantly affect rates of recurrence. In contrast, surgeon volume does appear to contribute significantly to durability of repair.

Heart failure with preserved ejection fraction (HFpEF) is a highly prevalent syndrome with an elevated risk of morbidity and mortality. To date, there is scarce evidence on the role of peak exercise oxygen uptake (peak VO 2 ) for predicting the morbidity burden in HFpEF. We sought to evaluate the association between peak VO 2 and the risk of recurrent hospitalizations in patients with HFpEF. A total of 74 stable symptomatic patients with HFpEF underwent a cardiopulmonary exercise test between June 2012 and May 2016. A negative binomial regression method was used to determine the association between the percentage of predicted peak VO 2 (pp-peak VO 2 ) and recurrent hospitalizations. Risk estimates are reported as incidence rate ratios. The mean age was 72.5 ± 9.1 years, 53% were women, and all patients were in New York Heart Association functional class II to III. Mean peak VO 2 and median pp-peak VO 2 were 10 ± 2.8mL/min/kg and 60% (range, 47-67), respectively. During a median follow-up of 276 days [interquartile range, 153-1231], 84 all-cause hospitalizations in 31 patients (41.9%) were registered. A total of 15 (20.3%) deaths were also recorded. On multivariate analysis, accounting for mortality as a terminal event, pp-peak VO 2 was independently and linearly associated with the risk of recurrent admission. Thus, and modeled as continuous, a 10% decrease of pp-peak VO 2 increased the risk of recurrent hospitalizations by 32% (IRR, 1.32; 95%CI, 1.03-1.68; P = .028). In symptomatic elderly patients with HFpEF, pp-peak VO 2 predicts all-cause recurrent admission. Copyright © 2017 Sociedad Española de Cardiología. Published by Elsevier España, S.L.U.

Nipple sparing mastectomy is deemed surgically and oncologically safe based on a long lasting literature data from reviews of single institution series. This study aims at evaluating surgical and oncological outcomes of NSM on a large multi-institutional scale, by means of the Italian National registry. In July 2011 a panel of Italian specialists agreed upon and designed a National database of NSM. Centers with at least 150 cancers per year and following the National follow-up schedule guidelines could participate inserting any NSM case performed, retrospectively and prospectively from that moment on. In March 2015 analysis of data was accomplished. Dataset for this study consists of cases performed in the period between January 1st 2009 and December 31st 2014. 913 Women were included in the analysis, for a total of 1006 procedures. Prophylactic mastectomies were 124 (12.3%). MRI utilization increased over time. NSM failure rate, with NAC removal for any reason was 11.5%. NAC necrosis rate was 4.8%. Larger skin-flap necrosis rate was 2.3%. Major surgical complications rate was 4.4%. Oncological outcomes were calculated among primitive EBC cases only: locoregional recurrences rate was 2.9%, NAC recurrence 0.7%. Systemic recurrence rate was 1.0%. Five deaths (0.7%) were registered. More than 10% of NSM procedures are prophylactic mastectomies. MRI is gaining more importance over time. Surgical and oncological results show that NSM is effective. This National multicentric analysis enables a comparison of results with no geographical differences and a "safe" state of the art of NSM in Italy. Copyright © 2015 Elsevier Ltd.

Living-donor vs deceased-donor liver transplantation for patients with hepatocellular carcinoma.

PubMed

Akamatsu, Nobuhisa; Sugawara, Yasuhiko; Kokudo, Norihiro

2014-09-27

With the increasing prevalence of living-donor liver transplantation (LDLT) for patients with hepatocellular carcinoma (HCC), some authors have reported a potential increase in the HCC recurrence rates among LDLT recipients compared to deceased-donor liver transplantation (DDLT) recipients. The aim of this review is to encompass current opinions and clinical reports regarding differences in the outcome, especially the recurrence of HCC, between LDLT and DDLT. While some studies report impaired recurrence - free survival and increased recurrence rates among LDLT recipients, others, including large database studies, report comparable recurrence - free survival and recurrence rates between LDLT and DDLT. Studies supporting the increased recurrence in LDLT have linked graft regeneration to tumor progression, but we found no association between graft regeneration/initial graft volume and tumor recurrence among our 125 consecutive LDLTs for HCC cases. In the absence of a prospective study regarding the use of LDLT vs DDLT for HCC patients, there is no evidence to support the higher HCC recurrence after LDLT than DDLT, and LDLT remains a reasonable treatment option for HCC patients with cirrhosis.

Retrospective study of stage T1N0M0 or T2N0M0 glottic cancers diagnosed between 1st January 2000 and 31st December 2010 and treated by exclusive radiotherapy. Evaluation of survival, recurrence and larynx preservation rates. CLCC François-Baclesse and CHU de Caen. Fifty-nine patients (53 men and sixwomen) treated for glottic cancer (57 squamous cell carcinomas, two verrucous carcinomas) comprising 51 T1N0M0 and eight T2N0M0 tumours. Treatment with exclusive radiotherapy (mean dose of 70 Grays limited to the thyroid cartilage for 57 patients, with lymph node irradiation for two patients). In this series, five (9.8%) patients with stage T1N0M0 glottic cancer and three patients (37.5%) with stage T2N0M0 glottic cancer relapsed, corresponding to a global recurrence rate of 13.6%. Three of the eight recurrences involved lymph nodes exclusively (N), two patients relapsed exclusively at the primary tumour site (T) and three patients presented local and lymph node recurrence (T and N). Treatment consisted of salvage total laryngectomy with bilateral cervical lymph node dissection in three cases, bilateral cervical lymph node dissection and sensitized radiotherapy in two cases, exclusive chemotherapy in one case, cervical lymph node dissection and cervical radiotherapy in one case. The last patient with recurrence died prior to salvage therapy. The larynx preservation rate was 94.9%. In comparison with the literature, treatment of stage T1-T2N0M0 glottic cancer by exclusive radiotherapy gives very good results, with a larynx preservation rate of 95%.

Abstract Trial Design: In the double-blind, randomized, controlled trial, we aimed to evaluate the effects of compound tufuling oral liquid (CoTOL) on serum uric acid (sUA) levels and recurrence of acute gouty arthritis in intercritical and chronic gout treatment. Methods: A total of 210 patients with gout were screened from 8 hospitals to observe the sUA and acute gouty arthritis recurrence rate-reducing effects of CoTOL in intercritical and chronic gout during a 12-week treatment. We treated 139 and 71 patients with CoTOL and the placebo, respectively, and evaluated their sUA levels, acute gouty arthritis recurrence rate, and adverse events at week 0, 6, and 12. Results: Twenty-five and 12 patients in the treatment and control groups, respectively, had interrupted treatments, whereas 114 and 59 cases, respectively, completed their treatments. At the end of the 12-week treatment, the average decrease in sUA was 74.26 (95% confidence interval [CI]: 56.74–91.77 μmol/L) and 28.81 μmol/L (95% CI: 4.91–52.71 μmol/L) in the treatment and control groups, respectively (P = 0.004). The average decrease rate of sUA was 12.76% (95% CI: 9.82%–15.70%) and 4.57% (95% CI: 0.42%–8.71%) in the treatment and control groups, respectively (P = 0.004), and the gouty arthritis recurrence rate of the treatment group was lower than that of the control group (from week 6 to 12, 21.93% and 50.88% in the treatment and control group, respectively, P < 0.001; from baseline to week 12, 38.5% and 63.16%, respectively, P = 0.003). Severe adverse events were not observed in either groups, and fewer leucopenia incidences were observed in the treatment group than those in the control group (3/139 vs. 7/71, respectively, P = 0.033). Conclusion: CoTOL reduced sUA levels and effectively prevented acute arthritis recurrence in intercritical and chronic gout without serious adverse events. PMID:28296744

Patients with locally recurrent adenocarcinoma of the prostate following radiation therapy (RT) present a challenging problem. We prospectively evaluated the use of "high-dose-rate-like" prostate stereotactic body RT (SBRT) salvage for this circumstance, evaluating prostate-specific antigen response, disease-free survival, and toxicity. Between February 2009 and March 2014, 29 patients with biopsy-proven recurrent locally prostate cancer >2 years post-RT were treated. Median prior RT dose was 73.8 Gy and median interval to SBRT salvage was 88 months. Median recurrence Gleason score was 7 (79% was ≥7). Pre-existing RT toxicity >grade 1 was a reason for exclusion. Magnetic resonance imaging-defined prostate volume including any suspected extraprostatic extension, comprising the planning target volume. A total of 34 Gy/5 fractions was given, delivering a heterogeneous, high-dose-rate-like dose-escalation pattern. Toxicities were assessed using Common Terminology Criteria for Adverse Events, version 3.0, criteria. Twenty-nine treated patients had a median 24-month follow-up (range, 3-60 months). A median pre-SBRT salvage baseline prostate-specific antigen level of 3.1 ng/mL decreased to 0.65 ng/mL and 0.16 ng/mL at 1 and 2 years, respectively. Actuarial 2-year biochemical disease-free survival measured 82%, with no local failures. Toxicity >grade 1 was limited to the genitourinary domain, with 18% grade 2 or higher and 7% grade 3 or higher. No gastrointestinal toxicity >grade 1 occurred. Two-year disease-free survival is encouraging, and the prostate-specific antigen response kinetic appears comparable with that seen in de novo patients treated with SBRT, albeit still a preliminary finding. Grade ≥2 genitourinary toxicity was occasionally seen with no obvious predictive factor. Noting that our only brachytherapy case was 1 of the 2 cases with ≥grade 3 genitourinary toxicity, caution is recommended treating these patients. SBRT salvage of post-RT local recurrence appears clinically feasible, with longer term evaluation required to assess ultimate efficacy and late toxicity rates.

Despite significant advances in medical care and surgical techniques, pressure sore reconstruction is still prone to elevated rates of complication and recurrence. We conducted a retrospective study to investigate not only complication and recurrence rates following pressure sore reconstruction but also preoperative risk stratification. This study included 181 ulcers underwent flap operations between January 2002 and December 2013 were included in the study. We performed a multivariable logistic regression model, which offers a regression-based method accounting for the within-patient correlation of the success or failure of each flap. The overall complication and recurrence rates for all flaps were 46.4% and 16.0%, respectively, with a mean follow-up period of 55.4 ± 38.0 months. No statistically significant differences of complication and recurrence rates were observed among three different reconstruction methods. In subsequent analysis, albumin ≤3.0 g/dl and paraplegia were significantly associated with higher postoperative complication. The anatomic factor, ischial wound location, significantly trended toward the development of ulcer recurrence. In the fasciocutaneous group, paraplegia had significant correlation to higher complication and recurrence rates. In the musculocutaneous flap group, variables had no significant correlation to complication and recurrence rates. In the free-style perforator group, ischial wound location and malnourished status correlated with significantly higher complication rates; ischial wound location also correlated with significantly higher recurrence rate. Ultimately, our review of a noteworthy cohort with lengthy follow-up helped identify and confirm certain risk factors that can facilitate a more informed and thoughtful pre- and postoperative decision-making process for patients with pressure ulcers.

Radiofrequency ablation (RFA) is effective treatment for Barrett's esophagus (BE). However, some patients have recurrence after complete eradication of intestinal metaplasia (CEIM). We investigated the incidence of and factors associated with BE recurrence, with or without neoplasia, after RFA and CEIM using data from the national Veterans Affairs (VA) healthcare system. We performed a retrospective cohort study of Veterans with BE treated by RFA from 2005 through 2016 with follow-up endoscopy. Subjects were followed until BE recurrence, neoplasia, death until October 2016. CEIM, BE recurrence, and factors associated with recurrence were identified by review of medical records. We calculated incidence rates of BE recurrence, with and without neoplasia, after CEIM and identified predictors using Cox proportional hazards models. We identified 430 Veterans with BE who were treated with RFA; of these 337 achieved CEIM (78.4%). Most were men (98.6%), White (83.7%), and 66.0% had baseline dysplasia. Of those with CEIM, 98 patients (29.1%) had recurrence of BE during a total 906.0 patient-years of follow-up (median 1.9 years) after CEIM (incidence, 10.8%/patient-year). Dysplasia developed in 20 patients (2.2%/patient-year) and cancer in 3 patients (0.3%/patient-year). Baseline dysplasia (hazard ratio [HR], 1.71; 95% CI, 1.03-2.84) and long-segment BE (HR, 1.61; 95% CI, 1.03-2.54) increased risk of BE recurrence whereas treatment at high-volume RFA facilities reduced risk of BE recurrence (for quartile 4 vs quartile 1: HR, 0.16; 95% CI, 0.05-0.60). In a nationwide VA system study of outcomes of RFA for BE, we associated baseline dysplasia, long-segment BE, and treatment at low-volume RFA centers with recurrence of BE after CEIM. The findings call for performing these procedures in high-volume centers. Copyright © 2018 AGA Institute. Published by Elsevier Inc. All rights reserved.

OBJECTIVE The endoscopic endonasal approach (EEA) is commonly used for the treatment of craniopharyngioma; therefore, it is essential to analyze outcomes in order to understand the benefits and drawbacks. The goal of this paper was to evaluate the clinical features and outcomes associated with this treatment approach. METHODS From July 2010 to March 2016, 82 adult craniopharyngioma patients underwent an EEA at the authors' institution. Of these cases, intraoperative records and immediate postoperative MR images were available for 68 patients. The patients underwent systemized endocrinological evaluation. Eighteen of 68 patients who underwent EEA for recurrence or regrowth of residual lesions after previous surgical management were excluded in the analysis of the anatomical tumor classification. The authors retrospectively analyzed preoperative clinical features and previous anatomical classifications, focusing on the relationship of the pituitary stalk and tumor, to determine predictive factors for the clinical outcome, such as the extent of resection, visual function, endocrinological function, recurrence rate, and complications. RESULTS The mean tumor size was 2.5 cm (3.1 cm for primary tumors and 1.9 cm for recurrent lesions). Gross-total resection (GTR) was achieved in 62 (91.1%) patients (48 [96.0%] patients with primary tumors and 14 [77.8%] patients with recurrent tumors). The rate of GTR was higher in the primary group than in the group with recurrence (p = 0.038). The overall pre- and postoperative visual impairment scale (VIS) scores were 40.8 and 22.1, respectively (50.9 and 14.3 in the primary group and 30.7 and 29.9 in patients with recurrence, respectively). The improvement rate in VIS score was higher in the primary group than in the recurrent group (p = 0.001). Endocrinological function was improved in 4 patients (5.9%) and deteriorated in 32 of 68 patients (47.1%). Tumor invasion into the center of the pituitary stalk affected the postoperative outcomes most significantly. Cognitive dysfunction was observed in 22 patients before surgery and improved in 20 patients (90.9%) after surgery. Hydrocephalus was found in 7 patients and resolved after surgery in all cases. CSF leakage occurred in 2 (2.9%) of 68 patients and was repaired by revision surgery in both patients. Ten patients without CSF leakage also received antibiotics for the treatment of meningitis. The infection rate was higher in the recurrent group. Postoperative endocrinological evaluation showed no deficits in 12 patients and panhypopituitarism in 55 patients. The remaining patient had growth hormone deficiency. Forty-three patients had new-onset diabetes insipidus, and 1 patient had persistent diabetes insipidus after surgery. There were 2 (2.9%) cases of recurrence during the mean 30.7-month follow-up period; one patient underwent radiosurgery and the other underwent reoperation. CONCLUSIONS The EEA resulted in excellent surgical outcomes and acceptable morbidity rates, regardless of the anatomical location of the tumor. Invasion of the craniopharyngioma into the center of the pituitary stalk has strong predictive power for postoperative endocrinological outcome.

Elastic strain budget and inelastic deformation in northeast Japan

Sagiya, T.; Meneses Gutierrez, A. D. V.

2016-12-01

A degree of magnitude discrepancy between geodetic and geologic strain rates of the Japan islands has been debated for a long time. Ikeda (1996) hypothesized that geodetic strain rate is affected by interseismic locking at the plate interface, which was later supported by the occurrence of the 2011 Tohoku-oki earthquake. The hypothesis also predicts that the interseismic elastic strain must be fully released in association with large earthquakes and do not accumulates in time. However, there has been no such quantitative discussion about the elastic strain budget of the Japan Islands so far. A 261 km-long baseline connecting GEONET stations Ryotsu (950232) and Oshika (960550) runs across the northeast Japan in the E-W direction. The baseline length change shows interseismic contraction at 0.11 ppm/yr before 2011, and coseismic extension of about 20 ppm, which comprises only 200 years of interseismic strain. Geologically the recurrence interval of 2011-type giant earthquakes is estimated as 400-800 years, much longer than a prediction from the elastic strain budget. Menese-Gutierrez and Sagiya (2016) recently identified persistent crustal shortening of 4-10 mm/yr along the Japan Sea coastal area from continuous GPS data. This contribution of inelastic deformation corresponds to 10 30% of the total interseismic shortening. The discrepancy can be also partly resolved by considering the effects of M7-class earthquakes and inelastic deformation of the island arc. M7-class earthquakes such as the 1978 and 2005 Miyagi-oki earthquakes cause 0.05-0.10 cm of baseline extension every about 40 years, releasing about 10 % of the totals strain. In addition, a postseismic extension still continues after 5 years from the main shock. By assuming this postseismic phase continues for about 50-100 years, the total elastic strain budget is balanced for a recurrence interval of about 400 yrs. If we assume a longer recurrence interval, we need additional ingredients such as inelastic deformation in the Ou Backbone range, long-term budget balancing over multiple cycles, and significant temporal variation of interseismic strain rate.

Introduction The role of fixation of the mesh is especially important in the endoscopic technique. The fixation of mesh through penetrating techniques using staples, clips or screws is associated with a significantly increased risk of developing a post-herniotomy pain syndrome. Aim To demonstrate the safety and efficacy of the self-fixating anatomical Parietex ProGrip laparoscopic mesh (Sofradim Production, Trévoux France) used with laparoscopic transabdominal preperitoneal hernia repair. The incidence of chronic post-herniotomy pain and recurrence rate in the follow-up after 12 months were evaluated. Material and methods Data analysis included all patients who underwent inguinal hernia surgery at our Surgical Department within the period from 1.05.2013 to 31.12.2014, who fulfilled the inclusion criteria. Standard surgical technique was used. Data were prospectively entered and subsequently analyzed on the Herniamed platform. Herniamed is an internet-based register in German and English language and includes all data of patients who underwent surgery for some types of hernia. Results There were 95 patients enrolled in the group and there were in total 156 inguinal hernias repaired. The mean follow-up was 15.52 months. At the assessment at 1 year mild discomfort in the groin was reported in 2 patients (3.51%) (1–3 VAS). No recurrence or chronic postoperative pain was reported. Conclusions Laparoscopic inguinal hernia repair using the transabdominal preperitoneal technique with implantation of the ProGrip laparoscopic mesh is a fast, effective and reliable method in experienced hands, which according to our results reduces the occurrence of chronic post-operative inguinal pain with simultaneously a low recurrence rate.

Objective Because debate continues over the role of combination, platinum-based chemotherapy for platinum sensitive (PS), recurrent ovarian cancer (OC), we compared overall survival (OS), progression-free survival (PFS), confirmed complete response rate and time to treatment failure in this population. Methods Patients with recurrent stage III or IV OC, a progression-free and platinum-free interval of 6- 24 months after first-line platinum-based chemotherapy and up to 12 courses of a non-platinum containing consolidation treatment were eligible. Patients were randomized to IV pegylated liposomal doxorubicin (PLD) (30 mg/m2) plus IV carboplatin (AUC=5 mg/mL × min) once every 4 weeks (PLD arm) or IV carboplatin alone (AUC=5mg/mL × min) once every 4 weeks. Results The PLD arm enrolled 31 patients and the carboplatin alone arm 30 for a total of 61 patients out of 900 planned. Response rates were 67% for the PLD arm and 32% for the carboplatin only arm (Fisher’s exact p=0.02). The estimated median PFS was 12 and 8 months for PLD versus carboplatin alone. The estimated median OS on the PLD arm was 26 months and 18 months on the carboplatin only arm (p=0.02). Twenty-six percent of the patients on the PLD arm reported grade 4 toxicities, all hematological in nature. Conclusion This study was closed early because of slow patient accrual. The response rate, median PFS and OS results are intriguing. These data suggest that there may be an advantage to the PLD plus carboplatin combination treatment in patients with PS, recurrent OC. The regimen should be further tested. PMID:17949799

to study peculiarities of primary and recurrent disability due to ocular complications of diabetes in Tashkent over the years 2003-2012 and to assess the impact of risk factors on the effectiveness of laser photocoagulation of the retina. A total of 347 disability examination reports of diabetic patients with ocular complications were copied and 48 case histories of patients with type II diabetes who underwent laser photocoagulation of the retina - retrospectively analyzed. Stabilization of visual function was used as the effectiveness criterion. The rate of new cases of disability over the studied decade averaged 0.55 per 100,000 population per year, while that of recurrent disability was 1.8 times higher - 0.97. The overall rate of disability was not high - 1.53; at that, severe disability (i.e. grade I and II) prevailed. Both recurrent and primary disability groups were made up by middle-aged patients and those in their retirement age; however, in the recurrent disability group the number of young disabled people was 4.5 times higher than in the primary disability group. Studies of the effectiveness of laser photocoagulation of the retina in relation to the compensation of diabetes and blood pressure level showed that unstable general condition was associated with not only significant deterioration of visual function, but also complications, including severe. The rate of disability due to ocular complications of diabetes is generally not high, however, grades I and II disabilities that require greater social support has been found to prevail in both groups. Most of disabled people are middle-aged (working-age population), which also causes economic damage. In cases of decompensated diabetes and unstable blood pressure, the effectiveness of laser photocoagulation of the retina is reduced.

To create a relational database for monitoring lithiasic patients. We describe the architectural details and the initial results of the statistical analysis. Microsoft Access 2002 was used as template. Four different tables were constructed to gather demographic data (table 1), clinical and laboratory findings (table 2), stone features (table 3) and therapeutic approach (table 4). For a reliability analysis of the database the number of correctly stored data was gathered. To evaluate the performance of the database, a prospective analysis was conducted, from May 2004 to August 2009, on 171 stone free patients after treatment (EWSL, surgery or medical) from a total of 511 patients stored in the database. Lithiasic status (stone free or stone relapse) was used as primary end point, while demographic factors (age, gender), lithiasic history, upper urinary tract alterations and characteristics of the stone (side, location, composition and size) were considered as predictive factors. An univariate analysis was conducted initially by chi square test and supplemented by Kaplan Meier estimates for time to stone recurrence. A multiple Cox proportional hazards regression model was generated to jointly assess the prognostic value of the demographic factors and the predictive value of stones characteristics. For the reliability analysis 22,084 data were available corresponding to 702 consultations on 511 patients. Analysis of data showed a recurrence rate of 85.4% (146/171, median time to recurrence 608 days, range 70-1758). In the univariate and multivariate analysis, none of the factors under consideration had a significant effect on recurrence rate (p=ns). The relational database is useful for monitoring patients with urolithiasis. It allows easy control and update, as well as data storage for later use. The analysis conducted for its evaluation showed no influence of demographic factors and stone features on stone recurrence.

The objective of this study was to estimate the risk of a seizure relapse and the high-risk period of recurrence after antiepileptic drug (AED) withdrawal and to determine the predictive factors for a seizure relapse in adult patients with focal epilepsy who were seizure-free for more than 2years. Using the Wenzhou Epilepsy Follow-Up Registry Database, 200 adult patients with focal epilepsy were recruited, who were undergoing follow-up, met the inclusion criteria of this study, were seizure-free for more than 2years, began withdrawing between June 2003 and June 2014, and were followed up prospectively for at least 1year or until a seizure relapse. The risk of recurrence and the time to seizure relapse were analyzed by the Kaplan-Meier method, and the predictive factors were identified by the Cox proportional hazard regression model. A total of 99 patients had an unprovoked relapse during the follow-up period. The relapse rate was 49.5%, and each year, the recurrence probability of 12, 24, 36, 48, 60, 72, and 84months after AED withdrawal was 24.0%, 20.4%, 8.3%, 2.7%, 4.6%, 0.97%, and 0.98%, respectively. The two independent risk factors for recurrence after withdrawal in adult patients with focal epilepsy were a longer duration of active epilepsy and a shorter seizure-free period before withdrawal. The high-risk period of a seizure relapse in adult patients with focal epilepsy is the first 2years after withdrawal, and beyond 5years after withdrawal, seizures rarely relapse (relapse rate<1%). A seizure-free period for less than 4years before withdrawal is a predictive factor of risk for seizure recurrence after AED withdrawal in adult patients with focal epilepsy.

We investigated the prognostic significance of tumor location at the renal hilum near the sinus structure on the recurrence in T1 renal cell carcinoma (RCC). A total of 1,818 T1 RCC patients who underwent radical (RN) or partial nephrectomy (PN) from 1997 to 2011 were retrospectively reviewed. A hilar tumor was defined as a tumor abutting the main renal artery and/or vein or its segmental branches, without invasion. We compared the recurrence-free survival (RFS) rates between hilar and nonhilar T1 RCC and analyzed predictors of RFS after nephrectomy. Patients with hilar tumors showed a poorer 5-year RFS compared with nonhilar tumors both in T1a (89.7 vs. 98.5 %, p < 0.001) and T1b (81.6 vs. 95.1 %, p < 0.001) RCCs. Among patients who underwent RN and PN, hilar tumors were associated with lower 5-year RFS (87.6 vs. 97.2 % for RN, 78.1 vs. 98.2 % for PN, both p < 0.001). In T1a hilar tumor, PN was associated with poorer 5-year RFS than RN (79.5 vs. 93.0 %, p < 0.001). In multivariate analysis, a hilar location remained as an independent predictor of recurrence in both T1a and T1b tumors (both p = 0.001). Hilar tumors show a higher recurrence rate than nonhilar counterparts in T1 RCC. In T1a hilar tumors, PN demonstrated poorer RFS than RN. Potential intrinsic renal anatomical or lymphovascular structural differences as well as differences in cancer characteristics need further investigations.

Substantial portion of early arrhythmia recurrence after catheter ablation for atrial fibrillation (AF) is considered to be due to irritability in left atrium (LA) from the ablation procedure. We sought to evaluate whether 90-day use of antiarrhythmic drug (AAD) following AF ablation could reduce the incidence of early arrhythmia recurrence and thereby promote reverse remodelling of LA, leading to improved long-term clinical outcomes. A total of 2038 patients who had undergone radiofrequency catheter ablation for paroxysmal, persistent, or long-lasting AF were randomly assigned to either 90-day use of Vaughan Williams class I or III AAD (1016 patients) or control (1022 patients) group. The primary endpoint was recurrent atrial tachyarrhythmias lasting for >30 s or those requiring repeat ablation, hospital admission, or usage of class I or III AAD at 1 year, following the treatment period of 90 days post ablation. Patients assigned to AAD were associated with significantly higher event-free rate from recurrent atrial tachyarrhythmias when compared with the control group during the treatment period of 90 days [59.0 and 52.1%, respectively; adjusted hazard ratio (HR) 0.84; 95% confidence interval (CI) 0.73-0.96; P = 0.01]. However, there was no significant difference in the 1-year event-free rates from the primary endpoint between the groups (69.5 and 67.8%, respectively; adjusted HR 0.93; 95% CI 0.79-1.09; P = 0.38). Short-term use of AAD for 90 days following AF ablation reduced the incidence of recurrent atrial tachyarrhythmias during the treatment period, but it did not lead to improved clinical outcomes at the later phase.

The French alpha-fetoprotein (AFP) model has recently shown superior results compared to Milan criteria (MC) for prediction of hepatocellular carcinoma (HCC) recurrence after liver transplantation (LT) in European populations. The aim of this study was to explore the predictive capacity of the AFP model for HCC recurrence in a Latin-American cohort. Three hundred twenty-seven patients with HCC were included from a total of 2018 patients transplanted at 15 centres. Serum AFP and imaging data were both recorded at listing. Predictability was assessed by the Net Reclassification Improvement (NRI) method. Overall, 82 and 79% of the patients were within MC and the AFP model respectively. NRI showed a superior predictability of the AFP model against MC. Patients with an AFP score >2 points had higher risk of recurrence at 5 years Hazard Ratio (HR) of 3.15 (P = 0.0001) and lower patient survival (HR = 1.51; P = 0.03). Among patients exceeding MC, a score ≤2 points identified a subgroup of patients with lower recurrence (5% vs 42%; P = 0.013) and higher survival rates (84% vs 45%; P = 0.038). In cases treated with bridging procedures, following restaging, a score >2 points identified a higher recurrence (HR 2.2, P = 0.12) and lower survival rate (HR 2.25, P = 0.03). A comparative analysis between HBV and non-HBV patients showed that the AFP model performed better in non-HBV patients. The AFP model could be useful in Latin-American countries to better select patients for LT in subgroups presenting with extended criteria. However, particular attention should be focused on patients with HBV. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The purpose of this study was to perform a systematic review of the literature to compare outcomes of revision anterior stabilization surgeries based on technique. This study also sought to compare the impact of bone defects on outcomes. A systematic review of the electronic databases PubMed, Cochrane Central Register of Controlled Trials, and Scopus was performed in July 2012 and March 2013. Of 345 articles identified in the search, 17 studies with Level I to IV Evidence satisfied the inclusion criteria and were analyzed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Recurrent instability was defined as redislocation, resubluxation, or a positive apprehensive test after revision surgery. Procedures were categorized as arthroscopic Bankart repair, open Bankart repair, Bristow-Latarjet procedure, and other open procedures. In total, 388 shoulders were studied. Male patients comprised 74.1% of patients, 66.7% of cases involved the dominant shoulder, the mean age was 28.2 years, and the mean follow-up period was 44.2 months. The surgical procedures classified as "other open procedures" had the highest rate of recurrent instability (42.7%), followed by arthroscopic Bankart repair (14.7%), the Bristow-Latarjet procedure (14.3%), and open Bankart repair (5.5%). Inconsistent reporting of bone defects precluded drawing significant conclusions. A number of different procedures are used to address recurrent instability after a primary operation for anterior shoulder instability has failed. There is significant variability in the rate of recurrent instability after revision anterior shoulder stabilization surgery. Level IV, systematic review of Level I to IV studies.

This study aims to report our multicenter experience with diagnosis, management, and prognosis of anorectal gastrointestinal stromal tumors (GIST). We retrospectively reviewed cases treated and/or followed up at our institutions in the period 2000-2011. Fifteen patients were identified (eight men and seven women; mean age, 55 years). Presenting symptoms were rectal/perirectal (eight), rectovaginal space (four), or retrovesical/prostatic (three) mass. Primary surgical treatment was local excision (six), deep anterior resection (eight), and palliative diagnostic excision (one). Tumor mean size was 4.8 cm. All but two cases were high risk (Miettinen and Lasota, Semin Diagn Pathol 23:70-83, 2006). R0 resection was achieved in 46% of cases: one of six local excisions vs. five of seven deep anterior resection (16 vs. 71%, respectively). All three cases who received total mesorectal excision had R0. Non-R0 status was mainly due to opening of tumor capsule at surgery (Rx). Seven of 14 patients (50%) developed ≥1 pelvic local recurrences at a mean period of 48.4 months (mean follow-up, 61.6 months). Only two patients developed distant metastasis (adrenal, liver, and peritoneal). Recurrences developed after Rx (three), R1 (two), and unknown R-status (two). Successful mutational analysis in 13 patients revealed KIT mutations in all (10 exon 11, 2 exon 9, and 1 exon 13). Our results confirm the high local recurrence rate of anorectal GISTs (50%) which correlates with the common practice of suboptimal oncological primary tumor resection (Rx or R1 = 7/13). This uncommon subset of GISTs needs more standardized oncological surgical approach to minimize the propensity for local disease recurrence.

The efficacy of surgical resection for gastric cancer liver metastases (GCLMs) is currently debated. Hitherto, no large-scale clinical studies have been conducted. This retrospective multicentre study analysed a database of consecutive patients with either synchronous or metachronous metastases who underwent surgical R0 resection for GCLM between 1990 and 2010. Clinical data were collected from five cancer centres in Japan. Survival curves were assessed, and clinical parameters were evaluated to identify predictors of prognosis. A total of 256 patients were enrolled. The mean(s.d.) number of hepatic tumours resected was 2.0(2.4). The surgical mortality rate was 1.6 per cent. Median follow-up was 65 (range 1-261) months. Recurrences were detected in 192 patients (75.0 per cent). The median interval from hepatic resection to recurrence was 7 (range 1-72) months, and the dominant site of recurrence was the liver (72.4 per cent). Actuarial 1-, 3- and 5-year overall and recurrence-free survival rates were 77.3, 41.9 and 31.1 per cent, and 43.6, 32.4 and 30.1 per cent, respectively. Median overall and recurrence-free survival times were 31.1 and 9.4 months respectively. Multivariable analysis identified serosal invasion of the primary gastric cancer (hazard ratio (HR) 1.50; P = 0.012), three or more liver metastases (HR 2.33; P < 0.001) and liver tumour diameter at least 5 cm (HR 1.62; P = 0.005) as independent predictors of poor survival. Clinically resectable GCLM is rare, but strict and careful patient selection can lead to long-term survival following R0 surgical resection. © 2014 BJS Society Ltd.

Recently, 68 Ga-labeled prostate-specific membrane antigen (PSMA)-ligand positron-emission tomography (PET) imaging has been shown to improve detection rates in recurrent prostate cancer (PC). However, published studies include only small patient numbers at low prostate-specific antigen (PSA) values. For this study, 272 consecutive patients with biochemical recurrence after radical prostatectomy and PSA value between 0.2 and 1ng/ml were included. The 68 Ga-PSMA-ligand PET/computed tomography (CT) was evaluated, and detection rates were determined and correlated to various clinical variables using univariate and multivariable analyses. Subgroups of patients with very low (0.2-0.5ng/ml) and low (>0.5-1.0ng/ml) PSA values were analyzed. In total, lesions indicative of PC recurrence were detected in 55% (74/134) and 74% (102/138) with very low and low PSA values, respectively. Main sites of recurrence were pelvic or retroperitoneal lymph nodes metastases, followed by local recurrence and bone metastases with higher probability in the low versus very low PSA subgroup. Detection rates significantly increased with higher PSA values, primary pT≥3a, primary pN+ disease, grade group ≥4, previous radiation therapy, and concurrent androgen deprivation therapy (ADT) in univariate analysis. In a multivariable logistic regression model, concurrent ADT and PSA values were identified as most relevant predictors of positive 68 Ga-PSMA-ligand PET/CT. Further, prediction nomograms were established, which may help in estimating pretest PSMA-ligand PET positivity in clinical practice. In our study, 68 Ga-labeled prostate-specific membrane antigen (PSMA)-ligand positron-emission tomography (PET)/computed tomography (CT) detected recurrent disease after radical prostatectomy in 55% (74/134) and 74% (102/138) of patients with very low (0.2-0.5ng/ml) and low (>0.5-1.0ng/ml) prostate-specific antigen values, respectively. On the basis of these data, it seems reasonable to perform 68 Ga-PSMA-ligand PET/CT also in patients with early biochemical recurrence, as it can tailor further therapy decisions (eg, local vs systemic treatment). The established prediction nomograms can further assist urologists in discussions on the use of 68 Ga-PSMA-ligand PET/CT with their patients in specific clinical settings.

Objectives Spontaneous pneumothorax is a common pathology. International guidelines suggest pleurodesis for non-resolving air leak or recurrence prevention at second occurrence. This study comprehensively reviews the existing literature regarding chemical pleurodesis efficacy. Design We systematically reviewed the literature to identify relevant randomised controlled trials (RCTs), case–control studies and case series. We described the findings of these studies and tabulated relative recurrence rates or ORs (in studies with control groups). Meta-analysis was not performed due to substantial clinical heterogeneity. Results Of 560 abstracts identified by our search strategy, 50 were included in our systematic review following screening. Recurrence rates in patients with chest tube drainage only were between 26.1% and 50.1%. Thoracoscopic talc poudrage (four studies (n=249)) provided recurrence rates of between 2.5% and 10.2% with the only RCT suggesting an OR of 0.10 compared with drainage alone. In comparison, talc administration during video-assisted thoracic surgery (VATS) from eight studies (n=2324) recurrence was between 0.0% and 3.2%, but the RCT did not demonstrate a significant difference compared with bleb/bullectomy alone. Minocycline appears similarly effective post-VATS (recurrence rates 0.0–2.9%). Prolonged air leak and recurrence prevention using tetracycline via chest drain (n=726) is likely to provide recurrence rates between 13.0% and 33.3% and autologous blood patch pleurodesis (n=270) between 15.6% and 18.2%. Conclusions Chemical pleurodesis postsurgical treatment or via thoracoscopy appears to be most effective. Evidence for definitive success rates of each agent is limited by the small number of randomised trials or other comparative studies. PMID:27803156

We conducted a systematic review and meta-analysis to synthesize the evidence about predictors that may affect biochemical remission and recurrence after transsphenoidal surgery (TSS), radiosurgery (RS), and radiotherapy (RT) in Cushing disease. We searched multiple databases through December 2014 including original controlled and uncontrolled studies that enrolled patients with Cushing disease who received TSS (first-line), RS, or RT. We extracted data independently, in duplicates. Outcomes of interest were biochemical remission and recurrence. A meta-analysis was conducted using the random-effects model to estimate event rates with 95% confidence intervals (CIs). First-line TSS was associated with high remission (76% [95% CI, 72 to 79%]) and low recurrence rates (10% [95% CI, 6 to 16%]). Remission after TSS was higher in patients with microadenomas or positive-adrenocorticotropic hormone tumor histology. RT was associated with a high remission rate (RS, 68% [95% CI, 61 to 77%]; RT, 66% [95% CI, 58 to 75%]) but also with a high recurrence rate (RS, 32% [95% CI, 16 to 60%]; RT, 26% [95% CI, 14 to 48%]). Remission after RS was higher at short-term follow-up (≤2 years) and with high-dose radiation, while recurrence was higher in women and with lower-dose radiation. Remission was after RT in adults who received TSS prior to RT, and with lower radiation doses. There was heterogeneity (nonstandardization) in the criteria and cutoff points used to define biochemical remission and recurrence. First-line TSS is associated with high remission and low recurrence, while RS and RT are associated with reasonable remission rates but important recurrence rates. The current evidence warrants low confidence due to the noncomparative nature of the studies, high heterogeneity, and imprecision.

1995-03-01

HPV associated bowenoid papulosis of the anogenital region are classified as carcinoma in situ. The treatment can be difficult and recurrence rates are high. Extended surgical resections may have complications such as anal sphincter insufficiency. PDT does have some advantages and less side effects in the treatment of these tumors. We treated one female patient with an extended perianal bowenoid papulosis. Previous surgical resection led to local recurrence and partial sphincter insufficiency. Twenty-four hours before local laser light radiation (Ar-Dye laser, 630 nm wavelength), a systemic photosensitizer was applied (Photofrin II, 1.5 mg/kg BW). Four courses of PDT were performed within one year. We observed a total tumor necrosis in every radiation area. The previous sphincter insufficiency improved during the sessions. Side effects were rare. Pain in the radiation was stopped within 2 - 3 days under pain medication. PDT can induce a total local tumor necrosis in perianal bowenoid papulosis. Concerning local expansion, PDT can be a curable treatment.

Objectives: The aim of this prospective registry-based population study was to investigate the efficacy of extralevator abdominoperineal excision (ELAPE) regarding local recurrence rates within 3 years after surgery. Background: Local recurrence of rectal cancer is more common after abdominoperineal excision (APE) than after anterior resection. Extralevator abdominoperineal excision was introduced to address this problem. No large-scale studies with long-term oncological outcomes have been published. Methods: All Swedish patients operated on with an APE and registered in the Swedish ColoRectal Cancer Registry 2007 to 2009 were included (n = 1397) and analyzed with emphasis on the perineal part of the operation. Local recurrence at 3 years was collected from the registry. Results: The local recurrence rates at 3 years [median follow-up, 3.43 years (APE, 3.37 years; ELAPE, 3.41 years; not stated: 3.43 years)] were significantly higher for ELAPE compared with APE (relative risk, 4.91). Perioperative perforation was also associated with an increased risk of local recurrence (relative risk, 3.62). There was no difference in 3-year overall survival between APE and ELAPE. In the subgroup of patients with very low tumors (≤4 cm from the anal verge), no significant difference in the local recurrence rate could be observed. Conclusions: Extralevator abdominoperineal excision results in a significantly increased 3-year local recurrence rate as compared with standard APE. Intraoperative perforation seems to be an important risk factor for local recurrence. In addition to significantly increased 3-year local recurrence rates, the significantly increased incidence of wound complications leads to the conclusion that ELAPE should only be considered in selected patients at risk of intraoperative perforation.

To determine the success rate of direct vision internal urethrotomy (DVIU) in the treatment of short stricture recurrence after buccal mucosa graft urethroplasty (BMGU). Patients who underwent DVIU for the treatment of short, "veil-like" recurrent urethral strictures (<1 cm) after BMGU between October 2009 and 2013 were retrospectively identified within our urethroplasty database. Stricture recurrence was defined as maximum flow rate (Q max) <15 ml/s and a consecutively verified stricture in a combined retro- and antegrade voiding cystography or cystoscopy at a follow-up visit. The success rate of DVIU was assessed by Kaplan-Meier analysis. Univariable Cox regression analyses evaluated risk factors for stricture recurrence following DVIU. Forty-three patients underwent DVIU for short stricture recurrence after BMGU for bulbar (81.3 %), penile (14.0 %) and membranous (4.7 %) strictures. Relapse had occurred proximally to the buccal mucosa graft in 28 (65.1 %) and distally in 12 (27.9 %) patients, respectively. At a mean follow-up of 11.7 (±9.7) months, stricture recurrence was observed in 48.8 % of our patients. Stricture recurrence was significantly associated with weak urinary stream (9.3 ml/s vs. no recurrence 19.5 ml/s) and patient dissatisfaction (66.7 % vs. no recurrence 18.1 %; both p < 0.001). The overall success rate was 60.5 % 15 months after DVIU. The main limitations of this study are its retrospective design, the small sample size and the short follow-up. DVIU after BMGU showed a moderate success rate and therefore might be a viable treatment option in selected patients with very short strictures after BMGU. However, longer follow-up is warranted to prove long-term effectiveness.

The exact predictive factors for postoperative recurrence of chronic subdural hematoma (CSDH) are still unknown. Based on the preoperative magnetic resonance imaging (MRI), low recurrence rate of T1-hyperintensity hematoma was previously reported. We investigated the other types of radiological findings which are related to the recurrence rate of CSDH in large number of patients analyzed by multivariate logistic regression model. Preoperative MRI and postoperative computed tomography (CT) were performed and the influence of the preoperative use of antiplatelet or anticoagulant drugs was also studied. The overall recurrence rate was 9.3% (47 of 505 hematomas). The MRI T1-iso/hypointensity group showed a significantly higher recurrence rate (18.2%, 29 of 159) compared to the other groups (5.2%, 18 of 346; p < 0.001). Multivariate logistic regression analysis showed T1 classification was the solo significant prognostic predictor among various factors such as bilateral hematoma, antiplatelet or anticoagulant drug usage, residual hematoma on postoperative CT, and MRI classification (p < 0.001): adjusted odds ratio for the recurrence in T1-iso/hypointensity group relative to the T1-hyperintensity group was 5.58 [95% confidence interval (CI), 2.09–14.86] (p = 0.001). Postoperative residual hematoma and antiplatelet or anticoagulant drug usage did not increase the recurrence risk. The preoperative MRI findings, especially T1WI findings, have predictive value for postoperative recurrence of CSDH and the T1-iso/hypointensity group can be assumed to be a high recurrence risk group.

This study was designed to describe the various anatomical relations of the recurrent laryngeal nerve (RLN) during thyroid surgery in a Central African population. A prospective study was conducted between January 2012 and December 2012 in 5 otorhinolaryngology and head and neck surgery departments in Cameroon and Gabon. All patients undergoing total or subtotal thyroidectomy or loboisthmectomy with recurrent laryngeal nerve dissection, with no history of previous thyroid surgery, RLN dissection or tumour infiltration of the RLN, were included. Fifty-six patients were included, corresponding to 36 loboisthmectomies and 20 total or subtotal thyroidectomies. A total of 62 recurrent laryngeal nerves were identified: 32 on the right and 30 on the left. The course of the recurrent laryngeal nerve in relation to branches of the inferior thyroid artery (ITA) was retrovascular in 53.1% of cases on the right and 76.6% of cases on the left; transvascular in 15.6% of cases on the right and 13.4% of cases on the left. The course of the recurrent laryngeal nerve was modified by thyroid disease in 12.9% of cases. Six cases (9.7%) of extralaryngeal division of the recurrent laryngeal nerve were observed. No case of non-recurrent nerve was observed in this series. The anatomical relations of the recurrent laryngeal nerve with the inferior thyroid artery were very inconstant in this series and were predominantly retrovascular or transvascular in relation to the branches of the artery. The presence of extralaryngeal branches and modification of the course of the nerve by thyroid disease also introduced additional difficulties during recurrent laryngeal nerve dissection. The anatomical relations of the right recurrent laryngeal nerve in this African population differ from the classically described prevascular course. Copyright © 2015 Elsevier Masson SAS.

To assess the efficacy of a modified approach with transanal total mesorectal excision (taTME) using simple customized instruments in male patients with low rectal cancer. A total of 115 male patients with low rectal cancer from December 2006 to August 2015 were retrospectively studied. All patients had a bulky tumor (tumor diameter ≥ 40 mm). Forty-one patients (group A) underwent a classical approach of transabdominal total mesorectal excision (TME) and transanal intersphincteric resection (ISR), and the other 74 patients (group B) underwent a modified approach with transabdominal TME, transanal ISR, and taTME. Some simple instruments including modified retractors and an anal dilator with a papilionaceous fixture were used to perform taTME. The operative time, quality of mesorectal excision, circumferential resection margin, local recurrence, and postoperative survival were evaluated. All 115 patients had successful sphincter preservation. The operative time in group B (240 min, range: 160-330 min) was significantly shorter than that in group A (280 min, range: 200-360 min; P = 0.000). Compared with group A, more complete distal mesorectum and total mesorectum were achieved in group B (100% vs 75.6%, P = 0.000; 90.5% vs 70.7%, P = 0.008, respectively). After 46.1 ± 25.6 mo follow-up, group B had a lower local recurrence rate and higher disease-free survival rate compared with group A, but these differences were not statistically significant (5.4% vs 14.6%, P = 0.093; 79.5% vs 65.1%, P = 0.130). Retrograde taTME with simple customized instruments can achieve high-quality TME, and it might be an effective and economical alternative for male patients with bulky tumors.

To determine whether intrapartum amnioinfusion (AI) relieves recurrent moderate and severe variable decelerations in laboring women with clear or grade I meconium-stained amniotic fluid and reduces cesarean section rate for fetal distress. A randomized controlled trial was conducted in labor unit of Christian Medical College Hospital, Vellore, India, between October 2003 and September 2004. Women were randomized to receive AI (group I) and not to receive it (group II). A total of 150 women (75 in each group) were included in the study. There was significant relief of variable decelerations in group I and no difference in overall cesarean section rate but significant reduction in cesarean section rate for fetal distress in group I, and significant reduction in cesarean section rate for fetal distress in nulliparous women of group I. Neonatal acidemia was also significantly reduced in the nulliparous women receiving AI. The duration of maternal postpartum hospital stay was significantly reduced in group I. There were no adverse maternal or neonatal outcomes. AI was a beneficial therapeutic intervention in women patients showing fetal distress in first stage of labor, and it reduced cesarean section for fetal distress and neonatal acidemia.

Catheter-associated bloodstream infections (CABSIs) are common complications encountered with cancer treatment. The aims of this study were to analyze the factors associated with recurrent infection and catheter removal in pediatric hematology-oncology patients. All cases of CABSIs in patients attending the Department of Pediatric Hematology-Oncology between January 2008 and December 2010 were reviewed. A total of 44 episodes of CABSIs, including multiple episodes involving the same catheter, were identified in 31 children with cancer. The overall CABSIs rate was 7.4 infections per 1000 central venous catheter (CVC) days. The most frequent organism isolated was coagulase-negative Staphylococcus (CONS). The CVC was removed in nine (20.4%) episodes. We found that hypotension, persistent bacteremia, Candida infection, exit-side infection, neutropenia, and prolonged duration of neutropenia were the factors for catheter removal. There were 23 (52.2%) episodes of recurrence or reinfection. Mortality rate was found to be 9.6% in children with CABSIs. In this study, we found that CABSIs rate was 7.4 infections per 1000 catheter-days. CABSIs rates in our hematology-oncology patients are comparable to prior reports. Because CONS is the most common isolated microorganism in CABSIs, vancomycin can be considered part of the initial empirical regimen.

To report the 5-year oncological outcomes of robot-assisted radical prostatectomy from the largest series ever reported from Asia. A retrospective analysis of 800 Asian patients who were treated with robot-assisted radical prostatectomy from July 2005 to May 2010 in the Department of Urology and Urological Science Institute, Yonsei University College of Medicine, Seoul, Korea was carried out. The primary end-point was to evaluate the biochemical recurrence. The secondary end-point was to show the biochemical recurrence-free survival, metastasis-free survival and cancer-specific survival. A total of 197 (24.65%), 218 (27.3%), and 385 (48.1%) patients were classified as low-, intermediate- and high-risk patients according to the D'Amico risk stratification risk criteria, respectively. The median follow-up period was 64 months (interquartile range 28-71 months). The overall incidence of positive surgical margin was 36.6%. There was biochemical recurrence in 183 patients (22.9%), 38 patients (4.8%) developed distant metastasis and 24 patients (3%) died from prostate cancer. Actuarial biochemical recurrence-free survival, metastasis-free survival, and cancer-specific survival rates at 5 years were 76.4%, 94.6% and 96.7%, respectively. Positive lymph node was associated with lower 5-year biochemical recurrence-free survival (9.1%), cancer-specific survival (75.7%) and metastasis-free survival (61.9%) rates (P < 0.001). On multivariable analysis, among all the predictors, positive lymph node was the strongest predictor of biochemical recurrence, cancer-specific survival and metastasis-free survival (P < 0.001). Herein we report the largest robot-assisted radical prostatectomy series from Asia. Robot-assisted radical prostatectomy is confirmed to be an oncologically safe procedure that is able to provide effective 5-year cancer control, even in patients with high-risk disease. © 2016 The Japanese Urological Association.

To evaluate if esomeprazole prevents recurrent peptic ulcer in adult patients with a history of peptic ulcer receiving low-dose acetylsalicylic acid (ASA, aspirin) for cardiovascular protection in East Asia. In this prospective, randomised, double-blind, placebo-controlled trial conducted in Japan, Korea and Taiwan, eligible patients receiving low-dose ASA for cardiovascular protection (81-324 mg/day) were randomised to esomeprazole 20 mg/day or placebo for ≤72 weeks. All patients received concomitant mucosal protection (gefarnate 100 mg/day). The primary endpoint was time to ulcer recurrence (Kaplan-Meier analysis). Efficacy findings are presented up to week 48, as per a planned interim analysis within the study protocol. A total of 364 patients (79.9% men; mean age, 67.1 years) comprised the full analysis set (esomeprazole, n=182; placebo, n=182). There was a statistically significant difference in the time to ulcer recurrence between esomeprazole and placebo (HR 0.09; 96.65% CI 0.02 to 0.41; p<0.001). The estimated ulcer-free rate at week 12 was 99.3% (esomeprazole) and 89.0% (placebo). The high estimated ulcer-free rate for esomeprazole was maintained through to week 48 (98.3% vs. 81.2% of placebo-treated patients). No factors, other than female gender, reduced time to ulcer recurrence in addition to the effect of esomeprazole (p<0.001). Treatment with esomeprazole was generally well tolerated. Daily esomeprazole 20 mg is efficacious and well tolerated in reducing the recurrence of peptic ulcer in East-Asian patients with a history of ulcers who are taking low-dose ASA for cardiovascular protection.

Our aim was to analyze the utility of peripheral thyrotropin receptor (TSHR) messenger RNA (mRNA) in predicting and detecting the recurrence of differentiated thyroid cancer. Peripheral blood TSHR-mRNA was obtained in 103 patients before and after total thyroidectomy. An analysis was performed to correlate peripheral blood TSHR-mRNA concentration with oncologic outcomes. Tumor types were papillary (n = 92), follicular (n = 9) and Hürthle cell (n = 2) cancer. Preoperative TSHR-mRNA was ≥1.02 ng/μg in 85% (88/103). On follow-up (median 48 months), 10 patients (10 %) developed recurrence. Recurrence rate in patients with a preoperative TSHR-mRNA ≥ 1.02 ng/μg was 11% versus 0% in those with a lesser concentration. TSHR-mRNA correctly diagnosed 7 (70%) of 10 recurrences. Of 19 patients with positive thyroglobulin (Tg) antibodies, TSHR-mRNA confirmed disease-free status in 12 (63%) and recurrence in 1 (5%). For Tg, TSHR-mRNA and whole-body radioactive iodine scan, sensitivity was 70%, 70%, and 75%; specificity 94%, 76%, 97%; PPV 54%, 24%, and 67%; and NPV 97%, 96%, and 98%, respectively, in detecting recurrent disease. This study shows that patients with preoperative TSHR-mRNA ≥1.02 ng/μg may be at a greater risk for recurrence compared with those with a lesser concentration. In the presence of Tg antibodies, TSHR-mRNA accurately predicted disease status in 68% of patients. Its overall performance in detecting recurrence was similar to Tg and whole-body radioactive iodine scan, albeit with lower specificity and PPV. Copyright © 2015 Elsevier Inc. All rights reserved.

Posterior circulation ischemic stroke (IS) is generally considered an illness with a poor prognosis. However, there are no effective rating scales to predict recurrent stroke following it. Therefore, our aim was to identify clinical or radiological measures that could assist in predicting recurrent cerebral ischemic episodes. We prospectively enrolled 723 noncardiogenic posterior circulation IS patients with onset of symptoms <7 days. Stroke risk factors, admission symptoms and signs, topographical distribution and responsible cerebral artery of acute infarcts, and any recurrent IS or transient ischemic attack (TIA) within 1 year were assessed. Cox regression was used to identify risk factors associated with recurrent IS or TIA within the year after posterior circulation IS. A total of 40 patients (5.5%) had recurrent IS or TIA within 1 year of posterior circulation IS. Multivariate Cox regression identified chief complaint with dysphagia (hazard ratio [HR], 4.16; 95% confidence interval [CI], 1.69-10.2; P =0.002), repeated TIAs within 3 months before the stroke (HR, 15.4; 95% CI, 5.55-42.5; P <0.0001), responsible artery stenosis ≥70% (HR, 7.91; 95% CI, 1.00-62.6; P =0.05), multisector infarcts (HR, 5.38; 95% CI, 1.25-23.3; P =0.02), and not on antithrombotics treatment at discharge (HR, 3.06; 95% CI, 1.09-8.58; P =0.03) as independent predictors of recurrent IS or TIA. Some posterior circulation IS patients are at higher risk for recurrent IS or TIA. Urgent assessment and preventive treatment should be offered to these patients as soon as possible. © 2017 American Heart Association, Inc.

Stone recurrence is a common late adverse event after ERCP in patients with common bile duct stones (CBDS). Duodenal-biliary reflux (DBR) is considered a major cause of CBDS recurrence. However, specific evidence is still lacking. To investigate the DBR rate in patients with recurrent CBDS after ERCP. A prospective case-control study. A tertiary center. During follow-up, patients with a history of either recurrent CBDS (recurrence group) or nonrecurrent CBDS (control group) were invited to participate in the study. All patients had previously undergone successful CBDS removal by ERCP. Patients in the control group were matched with the recurrence group by age and gender in a 1:1 ratio. Patients with gallbladder stones, hepatolithiasis, remnant CBDS, CBD strictures, or stents were excluded. Standard barium meal examination, MRCP, and enhanced abdominal CT. DBR. Thirty-two patients with a history of recurrent CBDS and 32 matched control subjects were enrolled. Baseline characteristics and parameters regarding the first ERCP were comparable between the 2 groups. The DBR rate was significantly higher in the recurrent than in the control group (68.8% vs 15.6%, P < .001). Multivariate analysis indicated that DBR (OR, 9.59; 95% CI, 2.65-34.76) and acute distal CBD angulation (OR, 5.48; 95% CI, 1.52-19.78) were independent factors associated with CBDS recurrence. DBR rates in patients with no, single, or multiple recurrences were 15.6%, 60.9%, and 88.9%, respectively (P < .001). Intrahepatic bile duct reflux was more common in patients with multiple recurrences. Small sample size. DBR is correlated with CBDS recurrence in patients who had previously undergone ERCP. DBR and acute distal CBD angulation are 2 independent risk factors related to stone recurrence. ( NCT02329977.) Copyright © 2015 American Society for Gastrointestinal Endoscopy.

A number of factors can influence the reported outcomes of transsphenoidal surgery (TSS) for Cushing's disease - including different remission and recurrence criteria, for which there is no consensus. Therefore, a comparative analysis of the best treatment options and patient management strategies is difficult. In this review, we investigated the clinical outcomes of initial TSS in patients with Cushing's disease based on definitions of and assessments for remission and recurrence. We systematically searched PubMed and identified 44 studies with clear definitions of remission and recurrence. When data were available, additional analyses by time of remission, tumor size, duration of follow-up, surgical experience, year of study publication and adverse events related to surgery were performed. Data from a total of 6400 patients who received microscopic TSS were extracted and analyzed. A variety of definitions of remission and recurrence of Cushing's disease after initial microscopic TSS was used, giving broad ranges of remission (42.0-96.6%; median, 77.9%) and recurrence (0-47.4%; median, 11.5%). Better remission and recurrence outcomes were achieved for microadenomas vs macroadenomas; however, no correlations were found with other parameters, other than improved safety with longer surgical experience. The variety of methodologies used in clinical evaluation of TSS for Cushing's disease strongly support the call for standardization and optimization of studies to inform clinical practice and maximize patient outcomes. Clinically significant rates of failure of initial TSS highlight the need for effective second-line treatments. © 2015 European Society of Endocrinology.

Background We investigated the patients and microbiological risk factors that predispose to the development of primary breast abscesses and subsequent recurrence. Methods Patients with a primary breast abscess requiring surgical therapy between January 1, 2000 and December 31, 2006 were reviewed. Recurrent breast abscess was defined by the need for repeated drainage within 6 months. Patient characteristics were compared to the general population and between groups. Results A total of 89 patients with a primary breast abscess were identified; 12 (14%) were lactational and 77 (86%) were nonlactational. None of the lactational abscesses recurred, whereas 43 (57%) of the nonlactational abscesses did so (P < 0.01). Compared to the general population, patients with a primary breast abscess were predominantly African American (64% vs. 12%), had higher rates of obesity (body mass index > 30: 43% vs. 22%), and were tobacco smokers (45% vs, 23%) (P < 0.01 for all). The only factor significantly associated with recurrence in the multivariate logistic regression analysis was tobacco smoking (P = 0.003). Compared to patients who did not have a recurrence, patients with recurrent breast abscesses had a higher incidence of mixed bacteria (20.5% vs. 8.9%), anaerobes (4.5% vs. 0%), and Proteus (9.1% vs. 4.4%) but lower incidence of Staphylococcus (4.6% vs. 24.4%) (P < 0.05 for each). Conclusions Risk factors for developing a primary breast abscess include African American race, obesity, and tobacco smoking. Patients with recurrent breast abscesses are more likely to be smokers and have mixed bacterial and anaerobic infections. Broader antibiotic coverage should be considered for the higher risk groups.

In this study, we assess interdisciplinary surgical and medical parameters associated to recurrences of infected pressure ulcers. There is a little in the published literature regarding factors associated with the outcome of treatment of infected pressure ulcers. We undertook a single-center review of spinal injured adults hospitalized for an infected pressure ulcer or implant-free osteomyelitis and reviewed the literature on this topic from 1990-2015. We found 70 lesions in 31 patients (52 with osteomyelitis) who had a median follow-up of 2.7 years (range, 4 months to 19 years). The median duration of antibiotic therapy was 6 weeks, of which 1 week was parenteral. Clinical recurrence after treatment was noted in 44 infected ulcers (63%), after a median interval of 1 year. In 86% of these recurrences, cultures yielded a different organism than the preceding episode. By multivariate analyses, the following factors were not significantly related to recurrence: number of surgical interventions (hazard ratio 0.9, 95% confidence interval 0.5-1.5); osteomyelitis (hazard ratio 1.5; 0.7-3.1); immune suppression; prior sacral infections, and duration of total (or just parenteral) antibiotic sue. Patients with antibiotic treatment for <6 weeks had the same failure rate as those with as >12 weeks (χ test; P = 0.90). In patients with infected pressure ulcers, clinical recurrence occurs in almost two-thirds of lesions, but in only 14% with the same pathogen(s). The number of surgical debridements, flap use, or duration of antibiotic therapy was not associated with recurrence, suggesting recurrences are caused by reinfections caused by other extrahospital factors.

Serum bilirubin level, which may reflect the host defense against increased oxidative stress, is inversely associated with the risk of cancer development. In liver transplantation, the intrinsic bilirubin metabolism of donor liver is subsequently translated into recipient. Thus, we hypothesized that liver transplantation conducted with living donors with higher serum bilirubin reduces hepatocellular carcinoma (HCC) recurrence. Two hundred fifty recipients who underwent liver transplantation for treating HCC within the Milan criteria were included in the study. The association between donor preoperative total bilirubin concentration and the risk of HCC recurrence was analyzed using the Fine and Gray regression model with posttransplant death as a competing risk event with adjustment for tumor biology including α-fetoprotein, histological differentiation, and microvascular invasion. All donors were confirmed to have no underlying hepatobiliary diseases or hematological disorders. Donor preoperative total bilirubin concentration was 0.7 mg/dL in median and ranged from 0.2 to 2.7 mg/dL. Thirty-five (14.0%) recipients developed HCC recurrence. Multivariable analysis demonstrated that donor preoperative total bilirubin concentration was inversely associated with the recurrence risk (hazard ratio, 0.22; 95% confidence interval, 0.07-0.72; P = 0.013). The highest (≥1.0 mg/dL) versus lowest (≤0.6 mg/dL) tertile of donor preoperative total bilirubin showed a significant reduction of the recurrence risk (hazard ratio, 0.28; 95% confidence interval, 0.11-0.70; P = 0.006). Hepatocellular carcinoma recurrence risk decreases in relation to the increase in total serum bilirubin level of healthy living donors without underlying hepatobiliary or hematological disorders. Further validation of bilirubin as a potent anticancer substance against HCC is warranted.

To evaluate the epidemiology of perineal streptococcal infection and recurrence rates following amoxicillin treatment. We used laboratory logs in a single pediatric practice to identify patients 0-18 years of age with perineal cultures positive for group A Streptococcus (GAS) and reviewed their medical charts. We described epidemiologic features, determined recurrence rates following antibiotic treatment, and performed a case-control study to identify possible risk factors for recurrence in patients treated with amoxicillin. We found a perineal streptococcal infection rate of 4.6 per 10,000 patient encounters and a recurrence rate in 157 patients with perineal streptococcal infection of 12.4% after amoxicillin. In male patients, the predominant site of involvement was the perianal region (86%), and for female patients, the perivaginal area (62%). Nearly 80% of patients were 2-7 years of age (range 18 days-12.5 years). Perineal streptococcal infection and GAS pharyngitis followed a similar seasonal pattern of occurrence with 65% of perineal streptococcal infection occurring October through March. In patients with perineal streptococcal infection, 95% had a concomitant pharyngeal culture positive for GAS. Best predictive factors for recurrence after amoxicillin were longer duration of symptoms prior to diagnosis and having a sibling with perineal streptococcal infection at some time before or after the initial episode. Following treatment with amoxicillin, we found a low recurrence rate of 12.4%. Amoxicillin can be expected to be reliable first-line therapy for perineal streptococcal infection.

Objective The history of treatments for fistula-in-ano can be traced back to ancient times. Current treatment of transphincteric fistulae is controversial, with many options available. We reviewed the history of treatment using cutting setons and present our series of transphincteric fistulae in the light of the series in the literature. Design Literature review and case series. Setting Hospital based coloproctology service Participants 140 consecutive patients presenting with fistula-in-ano were included. Main Outcome Measures The literature pertaining to treatment of transphincteric fistula was reviewed, along with the outcome of various treatment methods for this condition. Data were collected for 140 consecutive patients presenting with fistula- in-ano were assessed for fistula healing, recurrence and complications. Results A total of 140 consecutive patients with fistula-in-ano were identified, of which 111 were cryptoglandular (79.3%). Eighty-one of these 111 were transphincteric (73.0%). At a median follow-up of 35 months (range, 2–83 months), 70 transphincteric fistulae had healed (86.4%), 10 were still undergoing treatment (12.3%) and one patient was lost to follow-up prior to treatment (1.2%). Two patients in this group required a stoma (2.5%), six patients developed recurrence (7.4%); three ‘true’ recurrences (3.7%). One (1.2%) developed a chronic fissure. There were no reported cases of incontinence. Conclusions The management of transphincteric fistula-in-ano is complex and controversial, for which no clear surgical procedure has gained acceptance as the gold standard. This study demonstrates that transphincteric fistulae can be successfully treated using cutting setons. A high healing rate (86.4%), low recurrence rate (7.4%) and a low complication rate (3.7%) are shown, which compares favourably with published rates over a long follow-up. PMID:26152674

Patients with recent ischemic stroke may have higher risk of atherothrombosis than stable patients with established vascular events. Our aims were to investigate 1-year atherothrombotic vascular event rates and to assess the risk factors for recurrent ischemic stroke in this population. This prospective cohort study was conducted between January 2007 and July 2009 at 313 hospitals in Japan. Outpatients who were at least 45 years of age and who had received oral antiplatelet therapy were enrolled within 2 weeks to 6 months from the last onset of noncardioembolic ischemic stroke. At 12 ± 3 months after enrollment, data on presence/absence of atherothrombotic vascular events were collected. The primary endpoint was the occurrence of fatal or nonfatal ischemic stroke. A total of 3452 patients were enrolled, and 3411 patients who had baseline data were included in the analysis. The 1-year event rate was 3.81% (95% confidence interval 3.15-4.48%) for fatal or nonfatal ischemic stroke and 0.84% (95% confidence interval 0.52-1.15%) for all-cause mortality. The annual rate of recurrent ischemic stroke was significantly higher in patients who had ischemic stroke at least twice than in patients who had first-ever ischemic stroke (5.02% vs 3.59%; P = .0313). In the multivariable Cox regression analysis, recurrent ischemic stroke was significantly associated with age (P = .0033), the presence of diabetes (P = .0129), and waist circumference ≥80 cm (P = .0056). Patients with recent ischemic stroke have a higher risk of stroke recurrence than stable patients enrolled in the REduction of Atherothrombosis for Continued Health (REACH) registry even though they received antiplatelet therapy. The rigorous management of risk factors is needed. Copyright © 2012 National Stroke Association. Published by Elsevier Inc. All rights reserved.

Stereotactic radiosurgery (SRS) is used to manage patients with Cushing disease (CD) who have failed surgical/medical management. Because many patients with recurrent/persistent CD lack an identifiable adenoma on neuroimaging, whole-sellar SRS has been increasingly used. Thus, we sought to define the outcomes of patients undergoing whole-sellar SRS. An international, multicenter, retrospective cohort design was used to define clinical/endocrine outcomes for patients undergoing whole-sellar SRS for CD. Propensity-score matching was used to compare patients undergoing whole-sellar SRS and patients who underwent discreet adenoma-targeted SRS. A total of 68 patients underwent whole-sellar SRS, with a mean endocrine follow-up of 5.3 years. The mean treatment volume was 2.6 cm 3 , and the mean margin dose was 22.4 Gy. The 5-year actuarial remission rate was 75.9%, and the median time to remission was 12-months. Treatment volumes >1.6 cm 3 were associated with shorter times to remission (P < 0.05). The 5-year recurrence-free survival rate was 86.0%. Decreased margin and maximum treatment doses were associated with recurrence (P < 0.05). New pituitary hormone deficiency occurred in 15 patients (22.7%). An additional 210 patients were identified who underwent adenoma-targeted SRS. There was no difference in remission rate, time to remission, recurrence-free survival or new endocrinopathy development between patients who underwent whole-sellar SRS and those who underwent discreet adenoma-targeted SRS. Whole-sellar GKRS is effective in controlling CD when an adenoma is not clearly defined on imaging or when an invasive adenoma is suspected at the time of initial surgery. Patients who undergo whole-sellar SRS have outcomes and rates of new pituitary hormone deficiency similar to those of patients who undergo discrete adenoma-targeted GKRS.

Abstract Simple bone cysts (SBCs) are benign bone tumors. However, the treatment of SBCs remains controversial because of their healing rate and the invasiveness of surgery. The purpose of the present study was to evaluate the treatment of SBCs using a cannulated hydroxyapatite (HA) pin. A total of 43 patients (35 males, 8 females; mean age 12.1 years; age range, 5–22 years) with SBCs were treated with continuous decompression by inserting ceramic HA pins between 1989 and 2014. The SBCs were located in the calcaneus in 23, the humerus in 15, the femur in 3, and the pelvis in 2 cases. In all patients, minimal fenestration of the cyst wall and curettage and multiple drilling in the cyst wall were performed, followed by insertion of the HA pin. The mean follow-up period was 26.6 months. Operating time, healing period, risk factors for recurrence, and the cure rate were evaluated. Healing was achieved without intervention in 38 patients after a mean of 6.4 months. Two patients had persistent small residual cysts, which had no changes after 1 year at the latest follow-up. There were 5 patients with recurrences (humerus 4, femur 1), who were cured by curettage and artificial bone grafting. The final healing rate by cannulation only using an HA pin was 88.2%. On Fisher exact test, age, site of SBCs, and distance from the physis were found to be significantly associated with SBC recurrence (P < 0.05). In the present study, cannulation using an HA pin for SBCs was found to be a useful technique, particularly for calcaneal cysts, because it is a minimally invasive procedure with a high cure rate. In patients <10 years, involvement of the humerus and contact with the growth plate were significant risk factors for SBC recurrence. PMID:26107670

EMR is not inferior to ESD for early Barrett’s and EGJ neoplasia: An extensive review on outcome, recurrence and complication rates

PubMed Central

Komeda, Yoriaki; Bruno, Marco; Koch, Arjun

2014-01-01

Background and study aims In recent years, it has been reported that early Barrett’s and esophagogastric junction (EGJ) neoplasia can be effectively and safely treated using endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD). Multiband mucosectomy (MBM) appears to be the safest EMR method. The aim of this systematic review is to assess the safety and efficacy of MBM compared with ESD for the treatment of early neoplasia in Barrett’s or at the EGJ. Methods A literature review of studies published up to May 2013 on EMR and ESD for early Barrett’s esophagus (BE) neoplasia and adenocarcinoma at the EGJ was performed through MEDLINE, EMBASE and the Cochrane Library. Results on outcome parameters such as number of curative resections, complications and procedure times are compared and reported. Results A total of 16 studies met the inclusion criteria for analysis in this study. There were no significant differences in recurrence rates when comparing EMR (10/380, 2.6 %) to ESD (1/333, 0.7 %) (OR 8.55; 95 %CI, 0.91 – 80.0, P = 0.06). All recurrences after EMR were treated with additional endoscopic resection. The risks of delayed bleeding, perforation and stricture rates in both groups were similar. The procedure was considerably less time-consuming in the EMR group (mean time 36.7 min, 95 %CI, 34.5 – 38.9) than in the ESD group (mean time 83.3 min, 95 %CI, 57.4 – 109.2). Conclusions The MBM technique for EMR is as effective as ESD when comparing outcomes related to recurrence and complication rates for the treatment of early Barrett’s or EGJ neoplasia. The MBM technique is considerably less time-consuming. PMID:26135261

Spontaneous haemarthrosis in the absence of anticoagulant medication or a bleeding disorder is a very rare complication after total knee arthroplasty. A case of recurrent spontaneous haemarthrosis following total knee replacement in a 69-year-old patient is reported. Angiography was used to aid the diagnosis. It demonstrated an abnormal blush of vessels around the anterior aspect of the knee joint, that was fed by genicular branches and a recurrent branch of the anterior tibial artery. Selective embolisation of the bleeding vessels with coils led to immediate control of the bleeding. No further recurrence of haemarthrosis has been recorded.

Background We evaluated the efficacy of imatinib plus hydroxyurea in patients with progressive/recurrent low-grade glioma. Methods A total of 64 patients with recurrent/progressive low-grade glioma were enrolled in this single-center study that stratified patients into astrocytoma and oligodendroglioma cohorts. All patients received 500 mg of hydroxyurea twice a day. Imatinib was administered at 400 mg per day for patients not on EIAEDs and at 500 mg twice a day if on EIAEDs. The primary endpoint was progression-free survival at 12 months (PFS-12) and secondary endpoints were safety, median progression-free survival and radiographic response rate. Results Thirty-two patients were enrolled into each cohort. Eleven patients (17%) had prior radiotherapy and 24 (38%) had received prior chemotherapy. The median PFS and PFS-12 were 11 months and 39%, respectively. Outcome did not differ between the histologic cohorts. No patient achieved a radiographic response. The most common grade 3 or greater adverse events were neutropenia (11%), thrombocytopenia (3%) and diarrhea (3%). Conclusions Imatinib plus hydroxyurea was well tolerated among recurrent/progressive LGG patients but this regimen demonstrated negligible anti-tumor activity. PMID:22371319

Chemotherapy with cisplatin plus fluorouracil is the current standard treatment for metastatic or recurrent esophageal cancer. We have developed a 2-weekly docetaxel combined with CF regimen and conducted a Phase I/II trial for metastatic or recurrent esophageal cancer (JCOG0807). Promising efficacy and safety were shown in JCOG0807, and we have commenced a Phase III trial in September 2014 to confirm the superiority of 2-weekly DCF to CF for patients with metastatic or recurrent esophageal cancer. A total of 240 patients will be accrued from 41 Japanese institutions over a period of 4 years. The primary end point is overall survival. The secondary end points are progression-free survival, response rate and proportion of adverse events.

To compare the safety and efficacy of conventional monopolar transurethral resection of bladder tumour (TURBT) and 2-micron continuous-wave laser resection (2-µm laser) techniques in the management of multiple nonmuscle-invasive bladder cancer (NMIBC), and to investigate long-term effects on tumour recurrence. Patients with multiple NMIBC were randomized to receive TURBT or 2-µm laser in a nonblinded manner. All patients received intravesical chemotherapy with epirubicin (40 mg/40 ml) for 8 weeks, beginning 1 week after surgery, followed with monthly maintenance therapy for 12 months. Three-year follow-up data of preoperative, operative and postoperative management were recorded. In total, 120 patients were included: 56 in the TURBT group and 64 in the 2-µm laser group. Intra- and postoperative complications (including bladder perforation, bleeding and irritation) were less frequently observed in the 2-µm laser group compared with the TURBT group. There were no significant differences in first time to recurrence, overall recurrence or occurrence of urethral strictures. The 2-µm laser resection method was more effective than TURBT in reducing rates of intra- and postoperative complications, but offered no additional benefit regarding tumour recurrence.

There has been no comprehensive injury report of elite-level amateur boxers in competition and training. We reviewed injuries in training and competition in the Great Britain (GB) amateur boxing squad between 2005 and 2009. Longitudinal, prospective injury surveillance over 5 years of the GB boxing squad from 2005 to 2009. 66 boxers passed through the squad. The location, region affected, description, and the duration of each injury were recorded by the team doctor and team physiotherapist. We recorded whether the injury occurred during competition or training, and also whether it was a new or a recurrent injury. The injury rate during competition was calculated as the number of injuries per 1000 h. More injuries affected the hand than any other body location. This was the case overall, in training and competition individually, and for both new and recurrent injuries. More injuries occurred during training than during competition, and most injuries were new rather than recurrent. Total injury rate during competition was 828 per 1000 h and hand injury rate in competition was 302 injuries per 1000 h. Hand injury rate in competition was significantly higher than at the other locations. The incidence of concussion is comparatively low. Injury prevention should aim to protect the hands and wrists of elite amateur boxers. Published by the BMJ Publishing Group Limited.

Thirty four patients with retinochoroiditis initially treated with medical treatment and later treated with laser photocoagulation around the foci were retrospectively evaluated for the risk of recurrence of the eretinochoroiditis. We used a Kaplan-Meier representation to show the evolution of the number of patients without recurrence as a function of time and as the number of patients followed up decreases (rate of patients without recurrence at 1 year: 86 +/- 12.3% for 26 patients exposed; at 2 years: 75 +/- 16.4% for 20 patients exposed; at 3 years and at 4 years 70 +/- 17% for 17 patients exposed). The recurrence rates were compared to the data previously published in the literature. We failed to demonstrate the efficacy of laser photocoagulation on inactive retinochoroiditis for prevention of recurrence of ocular toxoplasmosis. However, the heterogeneity of our series, the great amount of patients lost to follow up, and the heterogeneity of the recurrence rates of the literature contribute to explain that result.

There is some evidence that greater consumption of fruit and vegetables decreases the risk of bladder cancer. The role of fruit and vegetables in bladder cancer recurrence is still unknown. The role of total fruit and vegetable intake in relation to the risk of developing bladder cancer recurrence in a prospective cohort study. 728 patients with non-muscle invasive bladder cancer (NMIBC), who completed self-administrated questionnaires on fruit and vegetable intake at time of diagnosis (over the year before diagnosis) and 1 year after diagnosis, were included. Hazard ratios and 95% confidence intervals were calculated by multivariable Cox regression for developing recurrent bladder cancer in relation to fruit and vegetable intake. During 2,051 person-years of follow-up [mean (SD) follow-up 3.7 (1.5) years], 241 (33.1%) of the included 728 NMIBC patients developed a recurrence of bladder cancer. The sum of total fruit and vegetables before diagnosis was not related to a first bladder cancer recurrence (HR 1.07; 95% CI 0.78-1.47, p = 0.66). No association was found between greater consumption of fruit and vegetables over the year before diagnosis and the risk of developing multiple recurrences of bladder cancer (HR 1.02; 95% CI 0.90-1.15, p = 0.78). Among the remaining 389 NMIBC patients who reported on fruit and vegetable intake 1 year after diagnosis, no association was found between greater consumption of fruit and vegetables and a first recurrence of bladder cancer (HR 0.65; 95% CI 0.42-1.01, p = 0.06) nor with multiple recurrences of bladder cancer (HR 1.00, 95% CI 0.85-1.18, p = 1.00). Similar results were obtained when investigating the association between total intakes of fruit and vegetables separately and bladder cancer recurrence. Results from this study did not indicate a protective role for total fruit and vegetables in the development of a recurrence of NMIBC.

Left ventricular hypertrophy (LVH) is an independent predictor of new-onset atrial fibrillation. Whether LVH can predict the recurrence of arrhythmia after radiofrequency catheter ablation (RFCA) in patients with paroxysmal atrial fibrillation (PAF) remains unclear. PAF patients with baseline-electrocardiographic LVH has a higher recurrence rate after RFCA procedure compared with those without LVH. A total of 436 patients with PAF undergoing first RFCA were consecutively enrolled and clustered into 2 groups based on electrocardiogram (ECG) findings: non-ECG LVH (218 patients) and ECG LVH (218 patients). LVH was characterized by the Romhilt-Estes point score system; the score ≥5points were defined as LVH. At 42 months' (interquartile range, 18.0-60.0 months) follow-up after RFCA, 151 (69.3%) patients in the non-ECG LVH group and 108 (49.5%) patients in the ECG LVH group maintained sinus rhythm without using antiarrhythmic drugs (P < 0.001). Patients with ECG LVH tended to experience a much higher prevalence of stroke and recurrence of atrial arrhythmia episodes compared with those without ECG LVH (log-rank P < 0.001). Multivariate analysis found the presence of ECG LVH and left atrial diameter to be independent risk factors for recurrence after adjusting for confounding factors. The presence of ECG LVH was a strong and independent predictor of recurrence in patients with PAF following RFCA. © 2018 Wiley Periodicals, Inc.

Winograd Method Versus Winograd Method With Electrocoagulation in the Treatment of Ingrown Toenails.

PubMed

Acar, Erdinc

An important component of the Winograd surgical method for an ingrown toenail is total excision of the associated germinal matrix. However, this might not always be accomplished with the procedure. We hypothesized that the surgical results might be improved by adding electrocoagulation of the germinal matrix to the Winograd method. The objective of the present study was to compare the recurrence, satisfaction, and complication rates of the Winograd method with those of the Winograd method with electrocoagulation. We retrospectively evaluated the records of 102 patients with single Heifetz stage 2 or 3 ingrown toenails who had undergone surgery from January 2013 to October 2014 using 1 of these 2 methods. Of the 102 patients, 50 (49%) underwent the Winograd method and 52 (51%) underwent the Winograd method with electrocoagulation. The mean follow-up period of our patients was 12 (range 6 to 22) months. An ingrown toenail recurred in 3 patients (6%) in the Winograd group and in no patient in the Winograd with electrocoagulation group (p = .04). Among the patients in the Winograd group, 46 (92.0%) were satisfied or very satisfied. Among the patients in the Winograd plus electrocoagulation group, 49 (94.2%) were satisfied or very satisfied (p = .04). No complications developed in either group. In conclusion, the Winograd method for ingrown toenails results in high satisfaction rates, low recurrence rates, and low complication rates. The addition of electrocoagulation of the germinal matrix to the Winograd method could result in even lower recurrence rates, while maintaining high patient satisfaction and without increasing the risk of complications.

Objective Obesity is strongly associated with incident gout risk; its association with risk of recurrent gout attacks has been null or weak, constituting an obesity paradox. We sought to demonstrate and overcome the methodologic issues associated with the obesity paradox for risk of recurrent gout attacks. Methods Using the MRFIT database, we decomposed the total effect of obesity into its direct and indirect (i.e., mediated) effects using marginal structural models. We also estimated the total effect of BMI change from baseline among incident gout patients. Results Of 11,816 gout-free subjects at baseline, we documented 408 incident gout cases, with 132 developing recurrent gout attacks over a 7-year follow-up. The adjusted odds ratio (OR) for incident gout among obese individuals was 2.6, while that for recurrent gout attacks among gout patients was 0.98 (i.e., the obesity paradox). These ORs correlated well with the ORs for the indirect and direct effects of obesity on risk of recurrent gout attacks (i.e., 2.83 and 0.98, respectively). Compared with no BMI change, the OR of losing vs. gaining >5% of baseline BMI was 0.61 and 1.60 for recurrent gout attacks, respectively (P for trend <0.01), suggesting a dose-response association. Conclusion The obesity paradox for risk of recurrent gout attacks is explained by the absence of the direct effect, which is often measured in conventional analyses and misinterpreted as the intended total effect of interest. In contrast, the BMI change analysis correctly estimated the intended total effect of BMI, and revealed a dose-response relationship. PMID:27331767

Microwave thermosphere ablation (MTA) is a new technology that is designed to create spherical zones of ablation using a single antenna. The aim of this study is to assess the results of MTA in a large series of patients. This was a prospective study assessing the use of MTA in patients with malignant liver tumors. The procedures were done mostly laparoscopically and ablation zones created were assessed for completeness of tumor response, spherical geometry and recurrence on tri-phasic CT scans done on follow-up. There were a total of 53 patients with an average of 3 tumors measuring 1.5 cm. Ablations were performed laparoscopically in all but eight patients. Morbidity was 11.3% (n = 6), and mortality zero. On postoperative scans, there was 99.3% tumor destruction. Roundness indices A, B, and transverse were 1.1, 1.0, and 0.9, respectively. At a median follow-up of 4.5 months, incomplete ablation was seen in 1 of 149 lesions treated (0.7%) and local tumor recurrence in 1 lesion (0.7%). The results of this series confirm the safety and feasibility of MTA technology. The 99.3% rate of complete tumor ablation and low rate of local recurrence at short-term follow up are promising. © 2015 Wiley Periodicals, Inc.

The procedure of choice for inguinal hernia repair has remained controversial for decades. The laparoscopic approach has now been utilized for more than 10 years, and a significant volume of patient outcomes is now available for review. The hospital and office records of 1388 patients who underwent 1903 laparoscopic inguinal hernia repairs at Atlanta Medical Center during the past 10 years were retrospectively reviewed in order to determine demographics, recurrence rate, and complications. In addition, 123 hernia repairs were prospectively studied in 71 patients during this time period in order to accurately evaluate postoperative pain and return to activity. Two hundred fifty-five (13.4%) hernias were recurrent and 1648 (86.6%) were primary. Five hundred and fifteen (37.1%) hernias were bilateral. The total extraperitoneal approach was utilized for 1561 (82.0%) of the 1903 repairs. The average operative time was 75.4 (14-193) minutes. Estimated blood loss was 22.0 (0-250) ml. Seventeen patients (1.2%) were converted to an open form of hernia repair. Minor complications occurred in 83 (6.0%) patients and major complications occurred in 18 (1.3%) patients. The laparoscopic approach is a safe form of inguinal hernia repair that offers the patient a shorter and less painful recovery with an extremely low recurrence rate.

The study by MacDonald et al. [Chemoradiotherapy after surgery compared with surgery alone for adenocarcinoma of the stomach or gastroesophageal junction. N Engl J Med 2001;345:725-30] has reported low loco-regional recurrence rates (19%) after gastric cancer resection and adjuvant radiotherapy. However, the lymph node dissection was often "inadequate". The aim of this retrospective study is to analyse if an extended lymph node dissection (D2) without adjuvant radiotherapy may achieve comparable loco-regional recurrence rates. A prospective database of 200 patients who underwent a curative resection for gastric carcinoma from January 2000 to December 2006 was analysed. D2 lymph node dissection was standard. Recurrences were categorized as loco-regional, peritoneal, or distant. No patients received neoadjuvant or adjuvant radiotherapy. The in-hospital mortality rate was 1% (2 patients). The mean number of dissected lymph nodes was 25.9. Overall and disease-free survival at 5years were 60.7% and 61.2% respectively. During the follow-up, 60 patients (30%) have recurred at 76 sites: 38 (50%) distant metastases, 25 (32.9%) peritoneal metastases, and 13 (17.1%) loco-regional recurrences. The loco-regional recurrence was isolated in 6 patients and associated with peritoneal or distant metastases in 7 patients. The mean time to the first recurrence was 18.9 (95% confidence interval: 15.0-21.9) months. Extended lymph node dissection is safe and warrants low loco-regional recurrence rates.

Case reports to suggest an algorithm for management of total fertilisation failure prior to use of donor gametes.

Total fertilisation failure (TFF), even with intracytoplasmic sperm injection (ICSI), occurs in approximately 3 % of cycles, can be recurrent and the exact cause is difficult to elucidate. Differentiation between oocyte and sperm-related cause of TFF is possible using mouse oocyte-activation techniques, but is not an option within most clinical settings. Therefore, the management of these couples is clinically driven, and the endpoint, if recurrent, is often the use of donor gametes. However, with the invariable lack of a definitive cause of TFF, any decision between the use of donor sperm or oocytes remains an emotive one. We present two case reports demonstrating the importance of appropriate investigation, activation techniques (mechanical and chemical) and clinical management options to develop a clinical algorithm prior to the use of donor gametes. This study is composed of two case reports of assisted reproduction investigation and treatment within an assisted conception unit for couples with recurrent total fertilisation failure. Using appropriate investigation (endocrine, urological and embryological) and treatments (ICSI, IMSI, oocyte-activation techniques), a fertilisation rate of 48 % was achieved in two cycles in couples following a total of nine previous cycles (and 200 previously collected eggs) with TFF. Oocyte activation requires the triggering of intracellular calcium oscillations by the release of a sperm-specific factor (phospholipase C zeta (PLCζ)) into the oocyte cytoplasm. Although, PLCζ deficiencies have been demonstrated as putative causes of failed activation, impaired oocyte responsiveness may also be a factor. The use of donor gametes is often recommended and is often the required endpoint of treatment. However, these reports outline a clinical algorithm that potentially offers success without donation, and also offers a systematic approach to help decide whether donor oocytes or sperm should be recommended.

The current role of Gamma Knife radiosurgery in the management of intracranial haemangiopericytoma.

2016-04-01

Haemangiopericytomas (HPCs) are rare tumours characterised by aggressive behaviour with tendency to local recurrence and to metastasise. WHO grade II and grade III tumours show different progression-free survival and overall survival rates. Gross total tumour resection is still considered the treatment of choice. Adjuvant radiation therapies represent an option in the treatment strategy regardless the extent of resection. Based on this consideration, Gamma Knife radiosurgery has been introduced either as a primary treatment or as an adjuvant treatment for residual or recurrent tumours. A systematic search was performed on PubMed, Web of Science and Google Scholar for clinical series reporting Gamma Knife radiosurgery, Cyberknife and Linear Accelerator (LINAC) for the management of intracranial HPCs. Fourteen studies focusing on the effects of Gamma Knife radiosurgery for intracranial HPCs were included. Four studies reported data on Cyberknife radiosurgery and LINAC. A total of 208 patients harbouring 366 tumours have been reported. Patient's features, radiosurgical treatment characteristics and follow-up data of the pertinent literature have been critically revised. Gamma Knife radiosurgery and the other radiosurgical techniques represent a feasible and effective therapy in the management of HPCs. Tumour control and survival rate are comparable to those reported for radiotherapy. Further studies should be focused to define the exact role of Gamma Knife radiosurgery in the management of HPCs.

PurposeApplication of metal stents is complicated by neointimal hyperplasia leading to vessel restenosis and reocclusion. Treatment options in cases presenting with complete occlusion of the stented segment and recurrent critical limb ischemia (CLI) are limited. We present the option of the subintimal/substent technique in dealing with occluded stents.MethodsThe study included patients presenting with recurrent CLI due to impaired blood flow as a result of complete occlusion of previously inserted metal stents and unsuccessful intraluminal crossing of the lesion via either the antegrade or retrograde approach. In these cases, crossing the occlusion through the subintimal/substent plane was attempted. Primary end pointsmore » included technical success, safety of the procedure, clinical improvement, and limb salvage, while secondary end points were patient survival, primary patency, and vessel restenosis rates at 1-year follow-up. Study end points were calculated by Kaplan-Meier survival analysis.ResultsBetween July 2006 and October 2011, a total of 14 patients (mean age 69.14 {+-} 12.59 years, 12 men) were treated with the substent technique and included in the analysis. Technical success rate was 85.71 % (12 of 14), with a total lesion length of 193.57 {+-} 90.78 mm. The mean occluded stented segment length was 90.21 {+-} 44.34 mm. In 10 (83.33 %) of 12 cases, a new stent had to be placed by the side of the old occluded one, while the remaining two cases (16.67 %) were treated only with balloon angioplasty. No serious adverse events were noted during the immediate postprocedural period. All successfully treated patients improved clinically. Estimated limb salvage was 90.9 %, and patient survival rate was 90.0 % at 1 year's follow-up. Primary patency was 45.50 % and vessel restenosis 77.30 %.ConclusionSubintimal recanalization of occluded metal stents through the substent plane is a valuable alternative treatment option, especially in patients with recurrent CLI with few alternatives.« less

Purpose: We retrospectively analyzed the impact of intraoperative radiation therapy (IORT) on long-term survival in patients with resectable gastric cancer. Methods and Materials: From 1991 to 2001, a total of 84 patients with gastric neoplasms underwent gastectomy or subtotal resection with IORT (23 Gy, 6-15 MeV; IORT-positive [IORT{sup +}] group). Patients with a history of additional neoadjuvant chemotherapy, histologically confirmed R1 or R2 resection, or reoperation with curative intention after local recurrence were excluded from further analysis. The remaining 61 patients were retrospectively matched with 61 patients without IORT (IORT-negative [IORT{sup -}] group) for Union Internationale Contre le Cancer (UICC)more » stage, patient age, histologic grading, extent of surgery, and level of lymph node dissection. Subgroups included postoperative UICC Stages I (n = 31), II (n = 11), III (n = 14), and IV (n = 5). Results: Mean follow-up was 4.8 years in the IORT{sup +} group and 5.0 years in the IORT{sup -} group. The overall 5-year patient survival rate was 58% in the IORT{sup +} group vs. 59% in the IORT{sup -} group (p = 0.99). Subgroup analysis showed no impact of IORT on 5-year patient survival for those with UICC Stages I/II (76% vs. 80%; p = 0.87) and III/IV (21% vs. 14%, IORT{sup +} vs. IORT{sup -} group; p = 0.30). Perioperative mortality rates were 4.9% and 4.9% in the IORT{sup +} vs. IORT{sup -} group. Total surgical complications were more common in the IORT{sup +} than IORT{sup -} group (44.3% vs. 19.7%; p < 0.05). The locoregional tumor recurrence rate was 9.8% in the IORT{sup +} group. Conclusions: Use of IORT was associated with low locoregional tumor recurrence, but had no benefit on long-term survival while significantly increasing surgical morbidity in patients with curable gastric cancer.« less

To study and compare the therapeutic effects of electroacupuncture and probiotics combine Deanxit in treating diarrhea predominant irritable bowel syndrome (D-IBS). Totally 64 D-IBS patients accompanied with anxiety and/or depression were randomly assigned to the Western medicine group (Group A) and the electroacupuncture (EA) group (Group B), 30 patients in Group A and 34 patients in Group B. Patients in Group A took Bacillus licheniformis and Deanxit, while those in Group B received EA. Four weeks consisted of one therapeutic course. Three-month follow-up was carried out. The scoring for the digestive tract symptoms, HAMA score, and HAMD score were evaluated before and after treatment. The recurrence in the 3-month follow-up was also observed. The total effect rate was 86.67% in Group A and 88.24% in Group B with no statistical difference between the two groups (P > 0.05). There was statistical difference in the scoring for the digestive tract symptoms, HAMA score, and HAMD score (P < 0.05, P < 0.01). There was no statistical difference in the improvement of defecation frequency score, HAMA score, HAMD score between the two groups after treatment (P > 0.05). Better effects on improving abdominal pain score and abdominal distention score was obtained in Group B (P < 0.01), while better effects on improving the stool form score and mucus score were obtained in Group A (P < 0.01). There was no statistical difference in the recurrence rate between the two groups within the two-month follow-up (P > 0.05). The recurrence rate within the 3-month follow-up was obviously lower in Group B than in Group A (P < 0.05). EA and Western medicine (probiotics combined Deanxit) could effectively treat D-IBS patients accompanied with anxiety and/or depression. Both of them had different superiorities in improving symptoms. But EA had better long-term therapeutic effects.

ABSTRACT Purpose To describe and analyze our experience with Anderson-Hynes transperitoneal laparoscopic pyeloplasty (LP) in the treatment of recurrent ureteropelvic junction obstruction (UPJO). Materials and methods 38 consecutive patients who underwent transperitoneal laparoscopic redo-pyeloplasty between January 2007 and January 2015 at our department were included in the analysis. 36 patients were previously treated with dismembered pyeloplasty and 2 patients underwent a retrograde endopyelotomy. All patients were symptomatic and all patients had a T1/2>20 minutes at pre-operative DTPA (diethylene-triamine-pentaacetate) renal scan. All data were collected in a prospectively maintained database and retrospectively analyzed. Intraoperative and postoperative complications have been reported according to the Satava and the Clavien-Dindo system. Treatment success was evaluated by a 12 month-postoperative renal scan. Total success was defined as T1/2≤10 minutes while relative success was defined as T1/2between 10 to 20 minutes. Post-operative hydronephrosis and flank pain were also evaluated. Results Mean operating time was 103.16±30 minutes. The mean blood loss was 122.37±73.25mL. The mean postoperative hospital stay was 4.47±0.86 days. No intraoperative complications occurred. 6 out of 38 patients (15.8%) experienced postoperative complications. The success rate was 97.4% for flank pain and 97.4% for hydronephrosis. Post-operative renal scan showed radiological failure in one out of 38 (2.6%) patients, relative success in 2 out of 38 (5.3%) patients and total success in 35 out of 38 (92.1%) of patients. Conclusion Laparoscopic redo-pyeloplasty is a feasible procedure for the treatment of recurrent ureteropelvic junction obstruction (UPJO), with a low rate of post-operative complications and a high success rate in high laparoscopic volume centers.

Sanabria, Álvaro; Ramírez, Adonis

2015-01-01

Thyroidectomy is a common surgery. Routine searching of the recurrent laryngeal nerve is the most important strategy to avoid palsy. Neuromonitoring has been recommended to decrease recurrent laryngeal nerve palsy. To assess if neuromonitoring of recurrent laryngeal nerve during thyroidectomy is cost-effective in a developing country. We designed a decision analysis to assess the cost-effectiveness of recurrent laryngeal nerve neuromonitoring. For probabilities, we used data from a meta-analysis. Utility was measured using preference values. We considered direct costs. We conducted a deterministic and a probabilistic analysis. We did not find differences in utility between arms. The frequency of recurrent laryngeal nerve injury was 1% in the neuromonitor group and 1.6% for the standard group. Thyroidectomy without monitoring was the less expensive alternative. The incremental cost-effectiveness ratio was COP$ 9,112,065. Routine neuromonitoring in total thyroidectomy with low risk of recurrent laryngeal nerve injury is neither cost-useful nor cost-effective in the Colombian health system.

Axillary dissection omission for sentinel lymph node-negative patients has been a practice at Cancer Institute Hospital, Japanese Foundation for Cancer Research since 2003. We examined the long-term results of omission of axillary dissection in sentinel lymph node-negative patients treated at our hospital, as well as their axillary lymph node recurrence characteristics and outcomes. Our study included 2,578 patients with cTis or T1-T3N0M0 primary breast cancer for whom dissection was omitted because they were sentinel lymph node negative. The median observation period was 75 months. In sentinel lymph node-negative patients for whom dissection was omitted, the rates of axillary lymph node recurrence, distant recurrence, and breast cancer mortality were 0.9, 2, and 1 %, respectively. Eighteen patients underwent additional dissection if axillary lymph node recurrence was observed at the first recurrence. Four triple-negative (TN) patients experienced distant recurrence after additional dissection. All four patients were administered anticancer agents after axillary lymph node recurrence and experienced recurrence within 1 year of additional dissection. The axillary lymph node recurrence rate was 0.8 % for luminal and 4.5 % for TN subtypes. The long-term prognoses of patients for whom dissection was omitted owing to negative sentinel lymph node metastases were similar to those reported previously-low recurrence and mortality rates. The frequency of axillary lymph node recurrence and the post-recurrence outcome differed between luminal and TN cases, with recurrence being more frequent in patients with the TN subtype. TN patients also had poorer prognoses, even after receiving additional dissection and anticancer agents after recurrence.

A pharmacokinetically guided phase I study of topotecan and etoposide phosphate was conducted in recurrent ovarian cancer. The scheduling of the topoisomerase I and II inhibitors was determined using in vitro activity data. All patients had recurrent disease following prior platinum-containing chemotherapy. Patients had a World Health Organisation performance status of 0-2 and adequate bone marrow, renal and hepatic function. Treatment was with topotecan intravenously for 5 days followed immediately by a 5-day intravenous infusion of etoposide phosphate (EP), with pharmacokinetically guided dose adjustment. Plasma etoposide levels were measured on days 2 and 4 of the infusion. A total of 21 patients entered the study. In all, 48% were platinum resistant and 71% had received prior paclitaxel. The main toxicities were haematological, short lived and reversible. A total of 29% of patients experienced grade 4 thrombocytopenia and 66% grade 4 neutropenia after the first cycle. Neutropenia and thrombocytopenia was dose limiting. The maximum-tolerated dose was topotecan 0.85 mg m(-2) day(-1) days 1-5 followed immediately by a 5-day infusion of EP at a plasma concentration of 1 mug ml(-1). The response rate (RR) was 28% in 18 evaluable patients. There was marked interpatient variability in topoisomerase IIalpha levels measured from peripheral lymphocytes, with no observed increase following topotecan. This regimen of topotecan followed by EP demonstrated good activity in recurrent ovarian cancer and was noncrossresistant with paclitaxel. Both the toxicity and RR was higher than would be expected from the single agent data, in keeping with synergy of action.

Disease relapses occur in up to 40% of cases after radiotherapy (RT) for early-stage glottic laryngeal neoplasms, and the foremost remaining treatment option is salvage total laryngectomy (STL). Our objectives were to review the outcomes of patients treated with salvage surgery after RT for early-stage carcinoma of the glottic larynx and to assess prognostic factors. We retrospectively analyzed 43 patients who underwent surgery. Overall and disease-free survival rates among subgroups were calculated and compared, stratified by preoperative stage, vocal cord mobility and postoperative histopathologic data. Recurrences occurred 22.7 months after the end of RT. Surgery was STL in 33 cases (76.8%). The main prognostic factors associated with survival rates were initial vocal cord mobility, vocal cord mobility at the diagnosis of recurrence, and changes in mobility. Vocal cord mobility is an important clinical criterion in treatment decision making for early-stage glottis carcinoma and remains important during follow-up.

Prevention and management of post-instability glenohumeral arthropathy

Post-instability arthropathy may commonly develop in high-risk patients with a history of recurrent glenohumeral instability, both with and without surgical stabilization. Classically related to anterior shoulder instability, the incidence and rates of arthritic progression may vary widely. Radiographic arthritic changes may be present in up to two-thirds of patients after primary Bankart repair and 30% after Latarjet procedure, with increasing rates associated with recurrent dislocation history, prominent implant position, non-anatomic reconstruction, and/or lateralized bone graft placement. However, the presence radiographic arthrosis does not predict poor patient-reported function. After exhausting conservative measures, both joint-preserving and arthroplasty surgical options may be considered depending on a combination of patient-specific and anatomic factors. Arthroscopic procedures are optimally indicated for individuals with focal disease and may yield superior symptomatic relief when combined with treatment of combined shoulder pathology. For more advanced secondary arthropathy, total shoulder arthroplasty remains the most reliable option, although the clinical outcomes, wear characteristics, and implant survivorship remains a concern among active, young patients.

This study aims to investigate the clinical curative effect of lymphocyte active immunotherapy (LAI) on unexplained recurrent spontaneous abortion (RSA). A total of 749 RSA patients who received medical service in our hospital from October 2009 to June 2013 were enrolled into this study. These patients were randomly divided into two groups: LAI group (treatment group) and routine progesterone for maintenance tocolysis group (control group). A comparative analysis on the pregnancy outcomes in these two groups was conducted. Abortion rate was significantly lower in the LAI group than in the control group (P<0.05). Furthermore, pregnancy success rates were 89.7% and 32.2% in patients who received LAI and routine progesterone for maintenance tocolysis, respectively, and the difference was statistically significant (P<0.05). Our analysis suggested that LAI can treat RSA effectively and has an excellent clinical effect. Furthermore, the detection of blocking antibodies showed a positive prediction on pregnancy outcome.

This article introduces 3-mm-deep eyelash trephination combined with electrocautery as a way to increase the success rate for treatment for trichiasis. We have modified surgical instruments, ready-made ophthalmic microtrephine and cautery tip for a 3-mm-deep eyelash trephination and electrocautery. After eyelash trephination with microtrephine, electrocautery was added with a bended cautery tip after embedding in the trephination site. The trephined eyelids were photographed biweekly and checked for recurrence until 8 weeks after operation. Eyelash trephination combined with electrocautery was carried out on 20 Korean patients. The number of removed cilia was 109. Of these, the number of successfully removed hair follicles was 89. During 8 weeks, the total recurring rate of eyelash trephination combined with electrocautery was 17%. In the case of hair follicle removal success with electrocautery, the recurring rate was as low as 11%, but in the case of hair follicle removal failure with electrocautery, recurring rate is 45%. We checked the depth of removed eyelash follicles, and the mean depth was 2.03 ± 0.085 mm in this study. No serious complication was found during the period of this study. The eyelash trephination combined with electrocautery for trichiasis is a method with a low recurrence rate and few complications. © 2011 The Authors.

Objective To evaluate the success rates and clinical outcomes of cervical cryotherapy applied to cervical ectopy for symptomatic relief. Subjects and Methods A total of 124 women who underwent cryotherapy for symptomatic treatment of cervical ectopy were included in this study. Indications for treatment were: abundant leucorrhoea (n = 114), post-coital bleeding (n = 22), recurrent cervicitis (n = 30) and pelvic pain (n = 12). Cryotherapy consisted of the use of carbon dioxide at −89°C to destroy the ectopic columnar epithelium by freezing, and it was transmitted to the ectopy through a flat cryoprobe. No routine anaesthesia or analgesia was administered. All patients were questioned about the status of their symptoms after 6 weeks of treatment. Results The highest success rate was obtained in patients with abundant leucorrhoea (n = 102; 89.5%), while the lowest success rate was achieved in subjects with pelvic pain (n = 7; 58%). After treatment, no severe complications were observed, except for hydrorrhoea for a few days. Success rates were 9 times lower in patients who had 3 or more cervicitis episodes per 6 months. Conclusion In this study, the success rate of cryotherapy was highest in patients with abundant leucorrhoea and lowest in patients with pelvic pain and recurrent cervicitis. Hence, we recommend that clinicians perform the procedure in such patients without much delay. PMID:26436550

To investigate the Human papilloma viral types 6 and 11 in a large pediatric population in XinJiang and the different expression in chinese and uyghur pediatric population. Using polymerase chain reaction (PCR), we analyzed paraffin embedded tissue in 42 cases of juvenile Recurrent Respiratory Papillomatosis (JRRP)and determined the HPV types 6 and 11, and to correlate these results with retrospectively analysis about those cases who were consecutively treated in our ENT department, meanwhile we carry out a critical review of the literature of JRRP. A total HPV infection positive rate was 97.61% (41/42), and HPV11 positive rate was 63.41% (41/26), HPV6 positive rate was 36.58% (41/15). In uyghur patient HPV11 positive rate was 65.38% (17/26), HPV6 positive rate was53. 33% (8/15). in Chince patient HPV11 positive rate was 34.61% (9/26), HPV6 positive rate was 46.67% (7/15). Juvenile laryngeal papilloma is associated with HPV11, HPV6 infection and we considered that HPV11 infection may be the important guideline of the evaluation of disease prognosis. but no statistical signtificance was determined in the patients of various ethnic groups in Xin jiang (P > 0.05).

Vulvovaginal candidiasis (VVC) is caused by abnormal growth of yeast-like fungi on the female genital tract mucosa. Patients with diabetes mellitus (DM) are more susceptible to fungal infections, including those caused by species of Candida. The present study investigated the frequency of total isolation of vaginal Candida spp., and its different clinical profiles - colonization, VVC and recurrent VVC (RVVC) - in women with DM type 2, compared with non-diabetic women. The cure rate using fluconazole treatment was also evaluated. Cross-sectional study conducted in the public healthcare system of Maringá, Paraná, Brazil. The study involved 717 women aged 17-74 years, of whom 48 (6.7%) had DM type 2 (mean age: 53.7 years), regardless of signs and symptoms of VVC. The yeasts were isolated and identified using classical phenotypic methods. In the non-diabetic group (controls), total vaginal yeast isolation occurred in 79 (11.8%) women, and in the diabetic group in 9 (18.8%) (P = 0.000). The diabetic group showed more symptomatic (VVC + RVVC = 66.66%) than colonized (33.33%) women, and showed significantly more colonization, VVC and RVVC than seen among the controls. The mean cure rate using fluconazole was 75.0% in the diabetic group and 86.7% in the control group (P = 0.51). We found that DM type 2 in Brazilian women was associated with yeast colonization, VVC and RVVC, and similar isolation rates for C. albicans and non-albicans species. Good cure rates were obtained using fluconazole in both groups.

Background. Cardiac tamponade (CT) represents a life-threatening condition, and the optimal method of draining accumulated pericardial fluid remains controversial. We have reviewed 100 patients with CT at our institution over a five-year period and compared the results of echo-guided pericardiocentesis, primary surgical treatment, and surgical treatment following pericardiocentesis with regard to functional outcomes. Methods. The study group consisted of 100 patients with CT attending Yuzuncu Yil University from January 2005 to January 2010 who underwent one of the 3 treatment options (echo-guided pericardiocentesis, primary surgical treatment, and surgical treatment following pericardiocentesis). CT was defined by clinical and echocardiographic criteria. Data on medical history, characteristics of the pericardial fluid, treatment strategy, and follow-up data were collected. Results. Echo-guided pericardiocentesis was performed in 38 (38%) patients (Group A), primary surgical treatment was preformed in 36 (36%) patients (Group B), and surgical treatment following pericardiocentesis was performed in 26 (26%) patients (Group C). Idiopathic and malignant diseases were primary cause of tamponade (28% and 28%, resp.), followed by tuberculosis (14%). Total complication rates, 30-day mortality, and total mortality rates were highest in Group C. Recurrence of tamponade before 90 days was highest in Group A. Conclusions. According to our results, minimal invasive procedure echo-guided pericardiocentesis should be the first choice because of lower complication and mortality rates especially in idiopathic cases and in patients with hemodynamic instability. Surgical approach might be performed for traumatic cases, purulent, recurrent, or malign effusions with higher complication and mortality rates. PMID:21941665

Despite advances in interdisciplinary treatment protocols, the chance of cure for recurrent head and neck squamous cell carcinoma (HNSCC) following failed primary therapy is poor and often entails a high morbidity. Recurrence rates vary widely in the literature depending on tumor localization, primary tumor stage, and treatment modality, and only a minority of patients can be salvaged. Historical cohort study. This study valuates the outcomes of patients treated for recurrent squamous cell carcinoma of the larynx, pharynx, and oral cavity in the largest tertiary referral center of Switzerland to find predictors for survival in salvage surgery with curative intent. Included were 176 consecutive patients with recurrent disease after primary curative treatment of HNSCC, in locations mentioned previously. Kaplan-Meier survival analyses with log-rank testing were performed depending on T and N stage, gender, treatment, and location of first relapse to evaluate the impact on overall survival, disease specific survival, and recurrence free survival. Overall successful salvage rates were 49.2% for laryngeal recurrence, 35.1% for oral cavity, 32.7% for oropharyngeal, and a mere 17.4% for hypopharyngeal recurrences. Predictive factors for better outcome were location of recurrence, female gender, lymph node status, and extent of salvage treatment. In case of recurrent disease, laryngeal cancers showed the best salvage rates, whereas in hypopharyngeal relapses, very few patients could be successfully salvaged. Patients therefore should be carefully selected and counseled for salvage treatment according to patient motivation, age, type of previous treatment, surgical resectability, and exclusion of distant recurrence. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

To explore the risk factors for recurrence of inferior vena cava (IVC)-type Budd-Chiari syndrome (BCS) after stenting and evaluate the feasibility and primary outcomes of endovascular therapies for recurrent BCS. A retrospective analysis of 219 patients was performed to identify risk factors for recurrence. The images of the recurrent patients during follow-up duration and interventional surgery were also reviewed to find the possible reasons of recurrence. The outcome of endovascular therapies for recurrent BCS was evaluated by Kaplan-Meier analysis. Among the 219 patients, 172 patients with primary IVC-type BCS underwent stenting and 28 patients experienced recurrence. Multivariate analysis identified age, Child-Pugh score, MELD and total bilirubin as independent recurrent indicators. Possible causes of recurrence include thrombosis in the stent, re-obstruction in or above the stent, and stent-related hepatic vein obstruction. Twenty-five patients with recurrent BCS underwent endovascular therapies with a few complications and achieved a high level of short- and mid-term patency. Age, total bilirubin and severity of liver function are the main risk factors for BCS recurrence. These risks might contribute to thrombosis or subsequent fibrous obstruction. Endovascular therapies are effective and safe management options that yield positive outcomes for recurrent BCS. • Risk factors for recurrent Budd-Chiari syndrome were identified by multivariate analysis. • Causes of recurrent Budd-Chiari syndrome were investigated by assessing radiological images. • There is a correlation between risk factors and causes of recurrence. • Endovascular therapies for recurrent Budd-Chiari syndrome are effective and safe.

Periprosthetic joint infection is a serious complication and reconstruction after failed revision total knee arthroplasty with significant bone loss and compromised soft-tissues can be challenging. Objective of this study was to assess clinical and functional results, implant survival and infection recurrence rates in patients treated with two-stage arthrodesis after failed revision TKA with extensor mechanism deficiencies due to PJI, and to identify the factors that affect outcomes after surgery. Thirty seven patients with PJI treated within a two-stage exchange and reimplantation of an arthrodesis nail between 2008 and 2014 were included. Systemic and local risk factors were graded preoperatively according to McPherson et al. All patients were treated according to a structured treatment algorithm. Clinical and functional evaluation was performed using the Oxford Knee Score and the Visual Analogue Scale. Thirty two of 37 patients (86.5%) were graded as free of infection. Five patients (13.5%) had recurrent infection after arthrodesis with the need of revision surgery. Mean leg-length discrepancy was 2.2cm. The mean VAS for pain was three, the mean Oxford Knee Score was 38±9. Total implant survival at a 74month follow-up was 74.3% (95% CI: 45.4 to 91.1%), as determined by Kaplan-Meier survival curves. Local McPherson Score, as well as number of revisions was found to be of significant influence to the survival rate. Septic failure of revision knee arthroplasty can be effectively treated with two-stage arthrodesis using a modular intramedullary nail, providing a stable and painless limb with satisfactory functional results and acceptable infection eradication rates.

The impact of occult lymph node metastasis on regional recurrence after prophylactic central neck dissection for preoperative, nodal-negative papillary thyroid cancer is controversial. We investigated risk factors for regional lymph node recurrence in papillary thyroid cancer patients who underwent total thyroidectomy and bilateral prophylactic central neck dissection. Analysis was according to clinicopathologic characteristics and occult lymph node metastasis patterns. This multicenter study enrolled 211 consecutive patients who underwent total thyroidectomy with bilateral prophylactic central neck dissection for papillary thyroid cancer without evidence of central lymph node metastasis on preoperative imaging. Clinicopathologic features and central lymph node metastasis patterns were analyzed for predicting regional recurrence. Multivariate Cox regression analysis was used to identify independent factors for recurrence. Median follow-up time was 43 months (24-95 months). Ten patients (4.7%) showed regional lymph node recurrence. The estimated 5-year, regional recurrence-free survival was 95.2%. Tumor size ≥1 cm, central lymph node metastasis, lymph node ratio, and prelaryngeal lymph node metastasis were associated with regional recurrence in univariate analysis (P < .05). In multivariate analysis, a lymph node ratio ≥ 0.26 was a significant risk factor for regional lymph node recurrence (odds ratio = 11.63, P = .003). Lymph node ratio ≥ 0.26 was an independent predictor of worse recurrence-free survival on Cox regression analysis (hazard ratio = 11.49, P = .002). Although no significant association was observed between the presence of occult lymph node metastasis and regional recurrence, lymph node ratio ≥ 0.26 was an independent predictor of regional lymph node recurrence in papillary thyroid cancer patients who underwent total thyroidectomy and bilateral prophylactic central neck dissection.

Chronic subdural hematoma is a commonly encountered disease in neurosurgic practice, whereas its increasing prevalence is compatible with the ageing population. Recommendations concerning postoperative thrombosis prophylaxis after burr-hole drainage of chronic subdural hematoma are lacking. The aim of this study was to analyze the correlation between recurrence of chronic subdural hematoma and postoperative application of thrombosis prophylaxis. Retrospective, consecutive sample of patients undergoing burr-hole drainage for chronic subdural hematoma over 3 years. Single, academic medical center. All patients undergoing surgical evacuation of a chronic subdural hematoma with burr-hole drainage. Exclusion: patients under the age of 18 years, who presented with an acute subdural hematoma and those who underwent a craniotomy. We compared patients receiving thrombosis prophylaxis treatment after burr-hole drainage of chronic subdural hematoma with those who were not treated. Primary outcome measure was reoperation of chronic subdural hematoma due to recurrence. Secondary outcome measures were thromboembolic and cardiovascular events, hematologic findings, morbidity, and mortality. In addition, a subanalysis comparing recurrence rate dependent on the application time of thrombosis prophylaxis (< 48 vs > 48 hr) was undertaken. Overall recurrence rate of chronic subdural hematoma was 12.7%. Out of the 234 analyzed patients, 135 (57.3%) received postoperative thrombosis prophylaxis (low-molecular-weight heparin) applied subcutaneously. Recurrence of chronic subdural hematoma occurred in the thrombosis prophylaxis group and control group in 12 patients (8.9%) and 17 patients (17.2%), respectively, showing no significant difference (odds ratio, 0.47 [95% CI, 0.21 - 1.04]). A subanalysis comparing recurrence rate of chronic subdural hematoma dependent on the application time of thrombosis prophylaxis (< 48 vs > 48 hr) showed no significant difference either (odds ratio, 2.80 [95% CI, 0.83-9.36]). Higher dosage of thrombosis prophylaxis correlated with recurrence rates of chronic subdural hematoma, both in univariate and multivariate analyses. Our data suggest that the application of postoperative thrombosis prophylaxis after burr-hole drainage for chronic subdural hematoma does not result in higher recurrence rates of chronic subdural hematoma. In addition, it seems that early administration of thrombosis prophylaxis (< 48 hr) has no influence on recurrence rates; however, high dosage seems to increase recurrence rates.

Preston et al. indicated that Protein S (PS) deficiency was associated with stillbirths but not miscarriages. The PS-Tokushima missense variant was reported to serve as a genetic risk factor for deep vein thrombosis in the Japanese population. A previous cross-sectional study showed no increase in the prevalence of PS-Tokushima in patients with recurrent early pregnancy loss or in patients with intra uterine fetal death and/or fetal growth restriction. There has been limited number of prospective studies examining the pregnancy outcome in patients with both a PS deficiency and recurrent pregnancy loss (RPL). We examined the association between PS deficiency, PS-Tokushima and RPL. The study group consisted of 355 Japanese women with two or more consecutive pregnancy losses and 101 parous women. The frequency of PS-Tokushima and the subsequent live birth rate in relation to a PS deficiency defined as low PS-specific activity (total PS activity/total PS antigen) and the carriage of PS-Tokushima were examined. There was no significant difference in the frequency of PS-Tokushima between patients and controls. The 8 patients carriers of PS-Tokushima variant were capable of a subsequent live birth without the use of heparin. There was no significant difference in subsequent live birth rates between patients with low or normal PS-specific activity/PS activity without heparin prophylaxis after excluding miscarriages caused by an abnormal embryonic karyotype using multivariate logistic regression analysis. There was no association between PS-Tokushima and RPL and a PS deficiency or low PS activity was shown not to serve as a reliable clinical predictor of subsequent miscarriage.

At present, few data exist regarding the comparisons of perioperative outcomes and recurrence of spontaneous ventilation (SV) video-assisted thoracic surgery (VATS) bullectomy using total intravenous anaesthesia (TIVA) with local anaesthesia (LA) or thoracic epidural anaesthesia (TEA). We evaluated the feasibility and safety of TIVA with LA in the management of primary spontaneous pneumothorax (PSP). We conducted a single-institution retrospective analysis of patients undergoing VATS bullectomy between July 2011 and May 2015; 240 patients were included for analysis. Preoperative, intraoperative and postoperative variables of patients undergoing VATS bullectomy using TIVA-TEA (n = 140) were compared with those using TIVA-LA (n = 100). Baseline demographics were similar between groups. No patients in either group required conversion to thoracotomy. Three patients (TIVA-TEA: 2; TIVA-LA: 1) required conversion to intubated general anaesthesia. Both groups had comparable surgical duration, estimated blood loss, peak EtCO 2 and lowest intraoperative SpO 2 level. Postoperatively, thoracic drainage volume, duration of chest tube drainage and hospitalization cost did not differ between groups. The incidence of postoperative complications between groups was not significant (2% for TIVA-TEA vs 2% for TIVA-LA, P = 1.00). Pneumothorax recurrence rate was 3% in TIVA-TEA cases (n = 4) and 2% in TIVA-LA cases (n = 2). SV-VATS bullectomy using TIVA with LA or TEA is technically feasible and safe. Both groups have comparable short-term outcomes and recurrence rates; TIVA-LA seems a valid alternative to TIVA-TEA for the surgical management of PSP under SV. © The Author 2016.

In many observational studies, the objective is to estimate the effect of treatment or state-change on the recurrent event rate. If treatment is assigned after the start of follow-up, traditional methods (eg, adjustment for baseline-only covariates or fully conditional adjustment for time-dependent covariates) may give biased results. We propose a two-stage modeling approach using the method of sequential stratification to accurately estimate the effect of a time-dependent treatment on the recurrent event rate. At the first stage, we estimate the pretreatment recurrent event trajectory using a proportional rates model censored at the time of treatment. Prognostic scores are estimated from the linear predictor of this model and used to match treated patients to as yet untreated controls based on prognostic score at the time of treatment for the index patient. The final model is stratified on matched sets and compares the posttreatment recurrent event rate to the recurrent event rate of the matched controls. We demonstrate through simulation that bias due to dependent censoring is negligible, provided the treatment frequency is low, and we investigate a threshold at which correction for dependent censoring is needed. The method is applied to liver transplant (LT), where we estimate the effect of development of post-LT End Stage Renal Disease (ESRD) on rate of days hospitalized.

Intraperitoneal free cancer cells in gastric adenocarcinoma are associated with a poor outcome. However, the true prognostic value of intraperitoneal free cancer cells is still unclear, leading to a lack of consensus in the management of gastric cancer. The aim of the present study is to perform a systematic review and meta-analysis to analyze intraperitoneal free cancer cells-positive patients with regard to tumor oncologic stage, recurrence, grade of cellular differentiation, and survival rates and to analyze the clinical significance of intraperitoneal free cancer cells with regard to prognosis. Databases were searched up to January 2016 for prognostic factors associated with intraperitoneal free cancer cells, including oncologic stage, depth of neoplasm invasion, lymph nodal spread, differentiation grade of the tumor, and recurrence and survival rates. A total of 100 studies were identified. Meta-analysis revealed a clear association between intraperitoneal free cancer cells and a poor prognosis. intraperitoneal free cancer cells -positive patients had higher rates of nodal spread (risk difference: 0.29; p<0.01), serosal invasion (risk difference: 0.43; p<0.01), recurrence (after 60 months of follow-up, risk difference: 0.44; p<0.01), and mortality (after 60 months of follow-up, risk difference: 0.34; p<0.01). Intraperitoneal free cancer cells are associated with a poor outcome in gastric cancer. This surrogate biomarker should be used to guide therapy both prior to and after surgery. PMID:28076519

Purpose: To determine the patterns of failure after intensity-modulated radiation therapy (IMRT) for localized intracranial ependymoma. Methods and Materials: From 1994 to 2005, 22 children with pathologically proven, localized, intracranial ependymoma were treated with adjuvant IMRT. Of the patients, 12 (55%) had an infratentorial tumor and 14 (64%) had anaplastic histology. Five patients had a subtotal resection (STR), as evidenced by postoperative magnetic resonance imaging. The clinical target volume encompassed the tumor bed and any residual disease plus margin (median dose 54 Gy). Median follow-up for surviving patients was 39.8 months. Results: The 3-year overall survival rate was 87% {+-}more » 9%. The 3-year local control rate was 68% {+-} 12%. There were six local recurrences, all in the high-dose region of the treatment field. Median time to recurrence was 21.7 months. Of the 5 STR patients, 4 experienced recurrence and 3 died. Patients with a gross total resection had significantly better local control (p = 0.024) and overall survival (p = 0.008) than those with an STR. At last follow-up, no patient had developed visual loss, brain necrosis, myelitis, or a second malignancy. Conclusions: Treatment with IMRT provides local control and survival rates comparable with those in historic publications using larger treatment volumes. All failures were within the high-dose region, suggesting that IMRT does not diminish local control. The degree of surgical resection was shown to be significant for local control and survival.« less

The Recurrence Score® is increasingly used in node-positive ER+ HER2-negative breast cancer. This retrospective analysis of a prospectively designed registry evaluated treatments/outcomes in node-positive breast cancer patients who were Recurrence Score-tested through Clalit Health Services from 1/2006 through 12/2011 ( N  = 709). Medical records were reviewed to verify treatments/recurrences/survival. Median follow-up, 5.9 years; median age, 62 years; 53.9% grade 2; 69.8% tumors ≤ 2 cm; 84.5% invasive ductal carcinoma; 42.0% N1mi, and 37.2%/15.5%/5.2% with 1/2/3 positive nodes; 53.4% Recurrence Score < 18, 36.4% Recurrence Score 18-30, and 10.2% Recurrence Score ≥ 31. Overall, 26.9% received adjuvant chemotherapy: 7.1%, 39.5%, and 86.1% in the Recurrence Score < 18, 18-30, and ≥ 31 group, respectively. The 5-year Kaplan-Meier estimates for distant recurrence were 3.2%, 6.3%, and 16.9% for these respective groups and the corresponding 5-year breast cancer death estimates were 0.5%, 3.4%, and 5.7%. In Recurrence Score < 18 patients, 5-year distant-recurrence rates for N1mi/1 positive node/2-3 positive nodes were 1.2%/4.4%/5.4%. As patients were not randomized to treatment and treatment decision is heavily influenced by Recurrence Score, analysis of 5-year distant recurrence by chemotherapy use was exploratory and should be interpreted cautiously: In Recurrence Score < 18, recurrence rate was 7.7% in chemotherapy-treated ( n  = 27) and 2.9% in chemotherapy-untreated patients ( n  = 352); P  = 0.245. In Recurrence Score 18-30, recurrence rate in chemotherapy-treated patients ( n  = 102) was significantly lower than in untreated patients ( n  = 156) (1.0% vs. 9.7% P  = 0.019); in Recurrence Score ≤ 25 (the RxPONDER study cutoff), recurrence rate was 2.3% in chemotherapy-treated ( n  = 89) and 4.4% in chemotherapy-untreated patients ( n  = 488); P  = 0.521. In conclusion, our findings support using endocrine therapy alone in ER+ HER2-negative breast cancer patients with micrometastases/1-3 positive nodes and Recurrence Score < 18.

The incidence of thyroid cancer has increased sharply year by year. Thyroid cancer ranked from the 14th in 2003 to the 4th in 2012 most common cancers in female in Beijing. Surgery is still main solution for thyroid cancer, there are two operative procedure for thyroid cancer: total thyroidectomy, lateral lobectomy and isthmus resection. The surgeon must pay attention to intraoperative recurrent laryngeal nerve and parathyroid injury, with particular emphasis on the prevention of total thyroidectomy complications. Precise dissection of thyroid capsule, intraoperative recurrent laryngeal nerve monitoring and application of lymphatic mapping to recognize and protect negative stained parathyroid by using carbon nanoparticles tracer is prone to reduce the incidence of recurrent laryngeal nerve and parathyroid injury in the total thyroidectomy.

The recurrence rate of sinonasal inverted papillomas (SNIP) is 15-20%. However, few studies have investigated patient-dependent factors related to recurrence of SNIPs. To analyze risk factors, including human papilloma virus (HPV) infection and smoking, as well as other factors, for recurrence of SNIPs. Fifty-four patients who were diagnosed with SNIP and underwent surgery were enrolled: 39 men and 15 women, with the mean age of 54.0 years. Their mean follow-up was 40.6 months. Demographics and information about the history of smoking, previous surgery, tumor extent, follow-up, and recurrence were reviewed retrospectively. Those patients whose tumors were associated with malignant transformation were excluded in this study. HPV detection and genotyping in the tumor specimens were performed with the HPV DNA chip, a polymerase chain reaction-based DNA microarray system. Seven patients (13.0%) had recurrence, with a mean time to recurrence of 39.8 months. Recurrence rates in T1, T2, T3, and T4 of the Krouse staging system were 0% (0/4), 8.3% (2/24), 17.4% (4/23), and 33.3% (1/3), respectively (p > 0.5). Eight patients (14.8%) were positive for HPV DNA. All of these patients belonged to the group without recurrence (p > 0.5). However, recurrence rates according to HPV DNA positivity were not statistically different (0% versus 15.2%). Three (42.9%) in the group with recurrence and four (8.5%) in the group without recurrence were smokers (p < 0.5). Smoking was associated with recurrence of SNIP. However, HPV infection is not a recurrence of SNIP risk factor.

High incidence of intrahepatic recurrence is a major surgical limitation following hepatectomy of hepatocellular carcinoma (HCC). This study was intended to investigate the effects of adjuvant intrahepatic injection of iodine-131-lipiodol on disease recurrence and survival in patients with HCC who underwent resection. A computerized literature search was performed to identify relevant articles. Data synthesis was performed using Review Manager 5.0 software, and results are presented as odds ratio (OR) with 95 % confidence intervals. Two randomized controlled trials and three case-control studies with a total of 334 participants were analyzed. Iodine-131-lipiodol treatment achieved significantly lower rates of intrahepatic recurrence (OR = 0.48, 95 % confidence interval (95 % CI) = 0.30-0.74; P = 0.001) and early recurrence (<2 year) (OR = 0.45, 95 % CI = 0.23-0.89; P = 0.02). Likewise, iodine-131-lipiodol treatment improved both the 5-year disease-free survival and overall survival significantly (OR = 1.85, 95 % CI = 1.13-3.03; P = 0.01; OR = 2.00, 95 % CI = 0.99-4.04; P = 0.05, respectively). Adjuvant intrahepatic injection of iodine-131-lipiodol resulted in a preventive effect on recurrence and improved survival after resection of HCC. Further larger, multi-centred, randomized prospective trial is warranted.

This study aimed to summarize the first experience with ultrasound-guided percutaneous ablation treatment (PAT) for recurrent hepatoblastoma (HB) after liver resection in children. From August 2013 to October 2014, PAT was used to treat 5 children with a total of 8 recurrent HB (mean size, 1.4 ± 0.8 cm; size range, 0.7–3.1 cm), including 4 patients with 7 tumors in the liver and 1 patient with 1 tumor in the lung. Technical success was achieved in all patients (5/5, 100%). The complete ablation rate after the first ablation session was 80% (4/5) on a patient-by-patient basis and 87.5% (7/8) on a tumor-by-tumor basis. Only 1 patient developed a fever with temperature >39 °C; it lasted 4 days after radiofrequency ablation (RFA) and was resolved by conservative therapy. During the follow-up period, new intrahepatic recurrences after PAT were detected in two patients. One died due to tumor progression 4 months after ablation. The median overall survival time after PAT was 13.8 months. PAT is a safe and promising therapy for children with recurrent HB after liver resection, and further investigation in large-scale randomized clinical trials is required to determine its role in the treatment of this disease.

To investigate the efficacy of fluticasone propionate aerosol (flixotide) versus budesonide suspension in the treatment of recurrent wheezing caused by bronchiolitis. A total of 214 infants with newly diagnosed bronchiolitis were randomly divided into flixotide treatment (106 infants) and budesonide treatment groups (108 infants), and were given aerosol inhalation of flixotide or budesonide for 3 months after achieving remission of clinical symptoms. Another 136 infants with bronchiolitis who did not receive regular inhalation of corticosteroid after achieving remission of clinical symptoms were enrolled as the control group. The follow-up visits were performed for 1 year, and the effects of the two therapeutic methods on recurrent wheezing were evaluated. Compared with the control group, both the flixotide and budesonide treatment groups had significantly fewer times of wheezing episodes within 1 year and a significantly lower recurrence rate of wheezing within the first 3 months after regular inhalation of corticosteroid, but no significant differences were observed between the two treatment groups. The amount of corticosteroid inhaled and hospital costs in the budesonide treatment group were significantly higher than in the flixotide treatment group (P<0.01). Continuous inhalation of flixotide or budesonide after remission of clinical symptoms in children with bronchiolitis can reduce wheezing episodes and the recurrence of wheezing, and flixotide treatment is superior to budesonide treatment in the aspects of hospital costs and the amount of corticosteroid used.

The optimal inguinal hernia repair has been controversial for decades. Since the advent of minimally invasive surgery, laparoscopic techniques have added to the controversy. Laparoscopic hernia repair has been advocated by many experts for the repair of bilateral and recurrent inguinal hernias. This study reviews the experience of a single community-based teaching hospital using the total extraperitoneal (TEP)-approach laparoscopic hernia repair for treating patients with bilateral and/or recurrent inguinal hernias. Since the TEP approach was adopted in June 1993, a total of 457 patients were treated for bilateral (322 patients) and/or recurrent (175) inguinal hernias (40 patients had recurrent and bilateral hernias). A total of 779 hernias were repaired with this technique. The average age of this patient group was 47 years, and there were 413 males and 44 females. Operative time averaged 68.3 minutes per patient, and there were 26 (5.7%) minor complications. There were 2 (0.4%) major complications, an enterotomy and a cystotomy, both early in the series and both in patients with previous lower abdominal surgery. There have been no deaths. With an average follow-up of 30 months (range, 1-60 months), there have been three (0.2%) recurrences. These recurrences were due to technical problems (inadequate mesh coverage), and each was repaired with a laparoscopic transabdominal approach or an anterior open approach. The use of the TEP-approach laparoscopic hernia repair is safe and effective in patients with recurrent and/or bilateral inguinal hernias.

To assess the impact of histology on recurrence patterns and survival outcomes in patients with esophageal cancer (EC) treated with definitive chemoradiotherapy (CRT). We analyzed 590 consecutive EC patients who received definitive CRT from 1998 to 2014, including 182 patients (30.8%) with squamous cell carcinoma (SCC) and 408 (69.2%) with adenocarcinoma. Recurrence pattern and timing, survival, and potential prognostic factors were compared. After a median follow-up time of 58.0months, the SCC group demonstrated a comparable locoregional recurrence rate (42.9% vs. 38.0%, P=0.264) but a significantly lower distant failure rate (27.5% vs. 48.0%, P<0.001) than adenocarcinoma group. No significant difference was found in overall survival or locoregional failure-free survival between groups, whereas the SCC group was associated with significantly more favorable recurrence-free survival (P=0.009) and distant metastasis-free survival (P<0.001). The adenocarcinoma group had higher hematogenous metastasis rates of bone, brain, and liver, whereas the SCC group had a marginally higher regional recurrence rate. Among patients who received salvage surgery after locoregional recurrence, no significant difference in survival was found between groups (P=0.12). The patterns and sites of recurrence, survival outcomes, and prognostic factors were significantly different between esophageal SCC and adenocarcinoma. Copyright © 2017 Elsevier B.V.

Prior analyses beyond clinical trials are yet to evaluate the projected lifetime benefit of apixaban treatment compared to low-molecular-weight heparin (LMWH)/vitamin K antagonist (VKA) for treatment of venous thromboembolism (VTE) and prevention of recurrences. The objective of this study is to assess the cost-effectiveness of initial plus extended treatment with apixaban versus LMWH/VKA for either initial treatment only or initial plus extended treatment. A Markov cohort model was developed to evaluate the lifetime clinical and economic impact of treatment of VTE and prevention of recurrences with apixaban (starting at 10 mg BID for 1 week, then 5 mg BID for 6 months, then 2.5 mg BID for an additional 12 months) versus LMWH/VKA for 6 months and either no further treatment or extended treatment with VKA for an additional 12 months. Clinical event rates to inform the model were taken from the AMPLIFY and AMPLIFY-EXT trials and a network meta-analysis. Background mortality rates, costs, and utilities were obtained from published sources. The analysis was conducted from the perspective of the United Kingdom National Health Service. The evaluated outcomes included the number of events avoided in a 1000-patient cohort, total costs, life-years, quality-adjusted life-years (QALYs), and cost per QALY gained. Initial plus extended treatment with apixaban was superior to both treatment durations of LMWH/VKA in reducing the number of bleeding events, and was superior to initial LMWH/VKA for 6 months followed by no therapy, in reducing VTE recurrences. Apixaban treatment was cost-effective compared to 6-month treatment with LMWH/VKA at an incremental cost-effectiveness ratio (ICER) of £6692 per QALY. When initial LMWH/VKA was followed by further VKA therapy for an additional 12 months (i.e., total treatment duration of 18 months), apixaban was cost-effective at an ICER of £8528 per QALY gained. Sensitivity analysis suggested these findings were robust over a wide range of inputs and scenarios for the model. In the UK, initial plus extended treatment with apixaban for treatment of VTE and prevention of recurrences appears to be economical and a clinically effective alternative to LMWH/VKA, whether used for initial or initial plus extended treatment.

The Nazca-South American convergence rate and the recurrence of the great 1960 Chilean earthquake

NASA Technical Reports Server (NTRS)

1986-01-01

The seismic slip rate along the Chile Trench estimated from the slip in the great 1960 earthquake and the recurrence history of major earthquakes has been interpreted as consistent with the subduction rate of the Nazca plate beneath South America. The convergence rate, estimated from global relative plate motion models, depends significantly on closure of the Nazca - Antarctica - South America circuit. NUVEL-1, a new plate motion model which incorporates recently determined spreading rates on the Chile Rise, shows that the average convergence rate over the last three million years is slower than previously estimated. If this time-averaged convergence rate provides an appropriate upper bound for the seismic slip rate, either the characteristic Chilean subduction earthquake is smaller than the 1960 event, the average recurrence interval is greater than observed in the last 400 years, or both. These observations bear out the nonuniformity of plate motions on various time scales, the variability in characteristic subduction zone earthquake size, and the limitations of recurrence time estimates.

Aims In the TRITON-TIMI 38 trial, greater platelet inhibition with prasugrel reduced the first occurrence of the primary endpoint (cardiovascular death, MI, or stroke) compared with clopidogrel in patients with an acute coronary syndrome (ACS) undergoing planned percutaneous coronary intervention. We hypothesized that prasugrel would reduce not only first events but also recurrent primary endpoint events and therefore total events compared with clopidogrel. Methods and results Poisson regression analysis was performed to compare the number of occurrences of the primary endpoint between prasugrel and clopidogrel in TRITON-TIMI 38. Landmark analytic methods were used to evaluate the risk of a recurrent primary endpoint event following an initial non-fatal endpoint event. Among patients with an initial non-fatal event, second events were significantly reduced with prasugrel compared to clopidogrel (10.8 vs. 15.4%, HR 0.65, 95% CI 0.46–0.92; P = 0.016), as was CV death following the non-fatal event (3.7 vs. 7.1%, HR 0.46, 95% CI 0.25–0.82; P = 0.008). Overall there was a reduction of 195 total primary efficacy events with prasugrel vs. clopidogrel (rate ratio 0.79, 95% CI 0.71–0.87; P < 0.001). Recurrent bleeding events occurred infrequently (TIMI major non-CABG bleeds: four with prasugrel and two with clopidogrel). Study drug discontinuation was frequent following the initial major bleeding event (42% of patients discontinued study drug). Conclusion While standard statistical analytic techniques for clinical trials censor patients who experience a component of the primary composite endpoint, total cardiovascular events remain important to both patients and clinicians. Prasugrel, a more potent anti-platelet agent, reduced both first and subsequent cardiovascular events compared with clopidogrel in patients with ACS. PMID:18682445

To compare the efficacy and safety of multiple treatment modalities for the management of chronic subdural hematoma (CSDH) patients. Current management strategies of CSDHs remain widely controversial. Treatment options vary from medical therapy and bedside procedures to major operative techniques. We searched MEDLINE (PubMed and Ovid), EMBASE, CINAHL, Google scholar, and the Cochrane library from January 1970 through February 2013 for randomized and observational studies reporting one or more outcome following the management of symptomatic patients with CSDH. Independent reviewers evaluated the quality of studies and abstracted the data on the safety and efficacy of percutaneous bedside twist-drill drainage, single or multiple operating room burr holes, craniotomy, corticosteroids as a main or adjuvant therapy, use of drains, irrigation of the hematoma cavity, bed rest, and treatment of recurrences following CSDH management. Mortality, morbidity, cure, and recurrence rates were examined for each management option. Randomized, prospective, retrospective, and overall observational studies were analyzed separately. Pooled estimates, confidence intervals (CIs), and relative risks (RRs) were calculated for all outcomes using a random-effects model. A total of 34,829 patients from 250 studies met our eligibility criteria. Sixteen trials were randomized, and the remaining 234 were observational. We included our unpublished single center series of 834 patients. When comparing percutaneous bedside drainage to operating room burr hole evacuation, there was no significant difference in mortality (RR, 0.69; 95% CI, 0.46-1.05; P = 0.09), morbidity (RR, 0.45; 95% CI, 0.2-1.01; P = 0.05), cure (RR, 1.05; 95% CI, 0.98-1.11; P = 0.15), and recurrence rates (RR, 1; 95% CI, 0.66-1.52; P = 0.99). Higher morbidity was associated with the adjuvant use of corticosteroids (RR, 1.97; 95% CI, 1.54-2.45; P = 0.005), with no significant improvement in recurrence and cure rates. The use of drains following CSDH drainage resulted in a significant decrease in recurrences (RR, 0.46; 95% CI, 0.27-0.76; P = 0.002). Craniotomy was associated with higher complication rates if considered initially (RR, 1.39; 95% CI, 1.04-1.74; P = 0.01); however, craniotomy was superior to minimally invasive procedures in the management of recurrences (RR, 0.22; 95% CI, 0.05-0.85; P = 0.003). Percutaneous bedside twist-drill drainage is a relatively safe and effective first-line management option. These findings may result in potential health cost savings and eliminate perioperative risks related to general anesthetic.

Extended Field Intensity Modulated Radiation Therapy With Concomitant Boost for Lymph Node–Positive Cervical Cancer: Analysis of Regional Control and Recurrence Patterns in the Positron Emission Tomography/Computed Tomography Era

DOE Office of Scientific and Technical Information (OSTI.GOV)

Vargo, John A.; Kim, Hayeon; Choi, Serah

Purpose: Positron emission tomography/computed tomography (PET/CT) is commonly used for nodal staging in locally advanced cervical cancer; however the false negative rate for para-aortic disease are 20% to 25% in PET-positive pelvic nodal disease. Unless surgically staged, pelvis-only treatment may undertreat para-aortic disease. We have treated patients with PET-positive nodes with extended field intensity modulated radiation therapy (IMRT) to address the para-aortic region prophylactically with concomitant boost to involved nodes. The purpose of this study was to assess regional control rates and recurrence patterns. Methods and Materials: Sixty-one patients with cervical cancer (stage IBI-IVA) diagnosed from 2003 to 2012 withmore » PET-avid pelvic nodes treated with extended field IMRT (45 Gy in 25 fractions with concomitant boost to involved nodes to a median of 55 Gy in 25 fractions) with concurrent cisplatin and brachytherapy were retrospectively analyzed. The nodal location was pelvis-only in 41 patients (67%) and pelvis + para-aortic in 20 patients (33%). There were a total of 179 nodes, with a median number of positive nodes of 2 (range, 1-16 nodes) per patient and a median nodal size of 1.8 cm (range, 0.7-4.5 cm). Response was assessed by PET/CT at 12 to 16 weeks. Results: Complete clinical and imaging response at the first follow-up visit was seen in 77% of patients. At a mean follow-up time of 29 months (range, 3-116 months), 8 patients experienced recurrence. The sites of persistent/recurrent disease were as follows: cervix 10 (16.3%), regional nodes 3 (4.9%), and distant 14 (23%). The rate of para-aortic failure in patients with pelvic-only nodes was 2.5%. There were no significant differences in recurrence patterns by the number/location of nodes, largest node size, or maximum node standardized uptake value. The rate of late grade 3+ adverse events was 4%. Conclusions: Extended field IMRT was well tolerated and resulted in low regional recurrence in node-positive cervical cancer. The dose of 55 Gy in 25 fractions was effective in eradicating disease in involved nodes, with acceptable late adverse events. Distant metastasis is the predominant mode of failure, and the OUTBACK trial may challenge the presented paradigms.« less

New minimally access hydrocelectomy.

PubMed

Saber, Aly

2011-02-01

To ascertain the acceptability of minimally access hydrocelectomy through a 2-cm incision and the outcome in terms of morbidity reduction and recurrence rate. Although controversy exists regarding the treatment of hydrocele, hydrocelectomy remains the treatment of choice for hydroceles. However, the standard surgical procedures for hydrocele can cause postoperative discomfort and complications. A total of 42 adult patients, aged 18-56 years, underwent hydrocelectomy as an outpatient procedure using a 2-cm scrotal skin incision and excision of only a small disk of the parietal tunica vaginalis. The operative time was 12-18 minutes (mean 15). The outcome measures included patient satisfaction and postoperative complications. This procedure requires minor dissection and minimal manipulation during treatment. It also resulted in no recurrence and minimal complications and required a short operative time.

1988-05-01

Of 1535 treated recall patients surveyed over an average time of 12.9 years since treatment was completed, 1371 had lost no teeth from periodontal disease. The total number of teeth lost was 444, with the average tooth loss for the 1535 patients being 0.29. In the three full arch splinted cases, the loss rate was 14.67 teeth per patient. Patients treated without any excisional or flap surgical procedures made up 26.5% of those surveyed, whereas 73.5% had required various surgical procedures. No attempt was made to compare different pocket therapy procedures. Although many patients developed recurrent periodontal problems during recall, only 15.9% of the 1535 patients required surgical retreatment. Teeth that were originally given a doubtful prognosis often were responsible for recurrent problems and sometimes required extraction.

Management of pediatric second branchial fistulae: is tonsillectomy necessary?

PubMed

Cheng, Jeffrey; Elden, Lisa

2012-11-01

To describe the surgical management of second branchial fistulae that extend to the pharynx, specifically to determine whether tonsillectomy, along with surgical excision of the tract affects the rate of recurrence. Retrospective chart review of pediatric patients (age<18) who underwent surgical excision of second branchial anomalies at a tertiary-care children's hospital between January 1, 2006 and September 1, 2011. Sinus tracts that extended to the pharynx were considered to be fistulae. Seventy-four patients were identified who underwent surgical excision of 85 total second branchial anomalies - 20 cysts (23.5%), 29 sinuses (34.1%), and 36 fistulae (42.4%). The 36 fistulae were removed from 32 patients, 23 males and 9 females, with an average age of 43.3 months. There were 16 right, 11 left, and 5 bilateral lesions. In 14 (43.8%) of the fistulae cases, a tonsillectomy was performed. There was only one recurrence (2.8%), which occurred 41 months postoperatively. No statistically significant difference for recurrence (p=1.0) was found between the group of patients that underwent tonsillectomy and those that did not. Pediatric branchial anomalies can present as a cyst, sinus, or fistula. They are developmental failures in the involution of the branchial apparatus during the embryologic period. Management of second branchial anomalies is with surgical excision of the tract and ligation of the terminal attachment to the pharynx. Our results suggest that the recurrence rates are not affected by whether or not an ipsilateral tonsillectomy is performed. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Objective Fertility sparing surgery (FSS) is a strategy often considered in young patients with early epithelial ovarian cancer. We investigated the role and the outcomes of FSS in eEOC patients who underwent comprehensive surgery. Methods From January 2003 to January 2011, 24 patients underwent fertility sparing surgery. Eighteen were one-to-one matched and balanced for stage, histologic type and grading with a group of patients who underwent radical comprehensive staging (n=18). Demographics, surgical procedures, morbidities, pathologic findings, recurrence-rate, pregnancy-rate and correlations with disease-free survival were assessed. Results A total of 36 patients had a complete surgical staging including lymphadenectomy and were therefore analyzed. Seven patients experienced a recurrence: four (22%) in the fertility sparing surgery group and three (16%) in the control group (p=not significant). Sites of recurrence were: residual ovary (two), abdominal wall and peritoneal carcinomatosis in the fertility sparing surgery group; pelvic (two) and abdominal wall in the control group. Recurrences in the fertility sparing surgery group appeared earlier (mean, 10.3 months) than in radical comprehensive staging group (mean, 53.3 months) p<0.001. Disease-free survival were comparable between the two groups (p=0.422). No deaths were reported. All the patients in fertility sparing surgery group recovered a regular period. Thirteen out of 18 (72.2%) attempted to have a pregnancy. Five (38%) achieved a spontaneous pregnancy with a full term delivery. Conclusion Fertility sparing surgery in early epithelial ovarian cancer submitted to a comprehensive surgical staging could be considered safe with oncological results comparable to radical surgery group.

We evaluated the long-term results of visual internal urethrotomy for pediatric urethral strictures to evaluate the efficacy and final outcome of this procedure in children and to evaluate the risk factors for stricture recurrence. The computerized surgical records of our hospital were reviewed to identify children who underwent visual internal urethrotomy between 1980 and 2001. Hospital and followup clinical charts were then reviewed. Many variables were analyzed, including age, etiology, length and site of the strictures, and catheter duration. Only patients with a minimum followup of 2 years were included. Regular self-catheterization was not used by any child. A total of 31 patients (mean age 11.2 years, range 2 to 18) were identified. Followup ranged from 2 to 20 years, with a mean of 6.6 years. The most common etiology for stricture formation was failed previous urethroplasty and post instrumentation (35.5% and 32.3%, respectively). The success rate after initial urethrotomy was 35.5% (11 of 31 patients). Mean interval to first recurrence was 26 months. A second urethrotomy improved the success rate of 58.1%. Eight patients required 2 or more urethrotomies, of whom half required open urethroplasty. Among the evaluated variables only stricture length shorter than 1 cm was associated with good results. Visual internal urethrotomy provides a safe first line therapeutic option for pediatric urethral strictures shorter than 1 cm, independent of etiology and location. For patients with more than 1 recurrence or with strictures longer than 1 cm, who are at high risk for recurrence after internal urethrotomy, open urethroplasty remains the treatment of choice.

Cranberry prophylaxis of recurrent urinary tract infection in infants has proven effective in the experimental model of the adult. There are few data on its efficacy, safety and recommended dose in the pediatric population. A controlled, double-blind Phase III clinical trial was conducted on children older than 1 month of age to evaluate the efficacy and safety of cranberry in recurrent urinary tract infection. The assumption was of the non-inferiority of cranberry versus trimethoprim. Statistical analysis was performed using Kaplan Meier analysis. A total of 85 patients under 1 year of age and 107 over 1 year were recruited. Trimethoprim was prescribed to 75 patients and 117 received cranberry. The cumulative rate of urinary infection associated with cranberry prophylaxis in children under 1 year was 46% (95% CI; 23-70) in children and 17% (95% CI; 0-38) in girls, effectively at doses inferior to trimethoprim. In children over 1 year-old cranberry was not inferior to trimethoprim, with a cumulative rate of urine infection of 26% (95% CI; 12-41). The cranberry was well tolerated and with no new adverse effects. Our study confirms that cranberry is safe and effective in the prophylaxis of recurrent urinary tract infection in infants and children. With the doses used, their efficiency is not less than that observed for trimethoprim among those over 1 year-old. (Clinical Trials Registry ISRCTN16968287).

To assess the ability to predict the local recurrence of hepatocellular carcinoma by analyzing tissues adhering to the radiofrequency ablation probe after complete ablation. From May 2002 to March 2011, tissue specimens adhering to the radiofrequency ablation probe from 284 radiofrequency ablation sessions performed for hepatocellular carcinomas ≤3 cm in size were analyzed. The specimens were classified as either viable tumor tissue or complete necrosis, and the local recurrence rates were calculated using the Kaplan-Meier method. From the tumors ≤3 cm in size, viable tissue was present in 6 (2.1%) of 284 specimens, and the local recurrence rates after 1 and 2 years of follow-up were 6.7% and 11.2%, respectively. Local recurrence developed significantly earlier in the viable tissue group. The recurrence rate was not significantly different based on whether transcatheter arterial chemoembolization was performed. The histopathology of the tissue adhering to the radiofrequency ablation probes used for hepatocellular carcinoma treatment can predict local recurrence. Additional aggressive treatment for patients with viable tissue can therefore improve the overall survival.

This study investigated the local effect and acute toxicity of irinotecan and capecitabine with concurrent intensity-modulated radiation therapy (IMRT) for the treatment of recurrent rectal cancer without prior pelvic irradiation. Seventy-one patients diagnosed with recurrent rectal cancer who did not previously receive pelvic irradiation were treated in our hospital from October 2009 to July 2012. Radiotherapy was delivered to the pelvis, and IMRT of 45 Gy (1.8 Gy per fraction), followed by a boost of 10 Gy to 16 Gy (2 Gy per fraction), was delivered to the recurrent sites. The concurrent chemotherapy regimen was 50 mg/m(2) irinotecan weekly and 625 mg/m(2) capecitabine twice daily (Mon-Fri). Radical surgery was recommended for medically fit patients without extra-pelvic metastases. The patients were followed up every 3 months. Tumor response was evaluated using CT/MRIs according to the RECIST criteria or postoperative pathological findings. NCI-CTC 3.0 was used to score the toxicities. Forty-eight patients (67.6%) had confirmed recurrent rectal cancer without extra pelvic metastases, and 23 patients (32.4%) had extra pelvic metastases. Fourteen patients (19.7%) underwent radical resections (R0) post-chemoradiation. A pathologic complete response was observed in 7 of 14 patients. A clinical complete response was observed in 4 patients (5.6%), and a partial response was observed in 22 patients (31.0%). Only 5 patients (7.0%) showed progressive disease during or shortly after treatment. Of 53 symptomatic patients, clinical complete and partial symptom relief with chemoradiation was achieved in 56.6% and 32.1% of patients, respectively. Only 2 patients (2.8%) experienced grade 4 leukopenia. The most common grade 3 toxicity was diarrhea (16 [22.5%] patients). The median follow-up was 31 months. The cumulative local progression-free survival rate was 74.2% and 33.9% at 1 and 3 years after chemoradiation, respectively. The cumulative total survival rate was 80.1% and 36.5% at 1 and 3 years after chemoradiation, respectively. This study revealed that concurrent irinotecan and capecitabine with IMRT significantly relieves local symptoms and exhibits promising efficacy with manageable toxicities in recurrent rectal cancer without prior pelvic irradiation. Improving the rate of R0 resections will be investigated in a future study.

The purpose of this study was to evaluate the risk factors for local recurrence with radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) measuring ≤2 cm. This study involved 234 patients with 274 HCCs measuring ≤2 cm who had undergone RFA as the initial treatment. The mean tumor diameter was 1.478 cm. The median follow-up period was 829 days. We evaluated the post-RFA cumulative local recurrence rate and analyzed the risk factors contributing to clinical outcomes. Cumulative local recurrence rates were 9, 19 and 19% at 1, 2 and 3 years, respectively. Among the 145 cases with a complete safety margin (SM) after RFA, only 4 developed local tumor recurrence and the cumulative rates of local tumor recurrence at 1, 2 and 3 years were 2, 3 and 3%, respectively. Among the 129 cases with incomplete SM, local tumor recurrence developed in 34 and the cumulative rates of local tumor progression at 1, 2 and 3 years were 14, 36 and 36%, respectively. In multivariate analysis, significant risk factors were tumor location (liver surface), irregular gross type and SM <5 mm. Even with HCC measuring ≤2 cm, location and gross type of tumor should be carefully evaluated before RFA is performed.

Transsphenoidal surgery (TSS) presents the treatment of choice for Cushing's disease (CD). Remission and recurrence rates vary dependent on tumor size, extension, adenoma visibility on magnetic resonance imaging, and neurosurgical expertise. Other than published from single-surgeon neurosurgical series so far, we have aimed to describe long-term remission and recurrence rates of CD in a series incorporating different neurosurgeons, trying to reflect care reality in the Munich Metropolitan Region, which is accommodated by three tertiary university and multiple, smaller neurosurgical centers. We conducted a retrospective analysis of 120 patients who underwent first and 36 patients who underwent second TSS as treatment for CD between 1990 and 2012. Patients were divided into three groups according to remission status. Potential risk factors for recurrence, pituitary function, and strategy in persistent disease were assessed. THREE OUTCOME GROUPS WERE IDENTIFIED ACCORDING TO REMISSION STATUS AFTER FIRST TSS (MEAN FOLLOW-UP 79 MONTHS): remission, 71% (85/120), disease persistence, 29% (35/120), and disease recurrence, 34% (29/85) (mean time to recurrence 54 months). After second TSS (n=36, mean follow-up 62 months), we documented remission in 42% (15/36), disease persistence in 58% (21/36), and disease recurrence in 40% (6/15) (mean time to recurrence 42 months). Postoperative hypocortisolism after first, though not after second, TSS was associated with a lower risk of suffering disease recurrence (risk=0.72; 95% CI 0.60-0.88; exact significance (two-sided) P=0.035). Our study shows higher recurrence rates of CD after first TSS than previously reported. Second TSS leads an additional 8% of the patients to long-term CD remission.

Objectives Fidaxomicin was non-inferior to vancomycin with respect to clinical cure rates in the treatment of Clostridium difficile infections (CDIs) in two Phase III trials, but was associated with significantly fewer recurrences than vancomycin. This economic analysis investigated the cost-effectiveness of fidaxomicin compared with vancomycin in patients with severe CDI and in patients with their first CDI recurrence. Methods A 1 year time horizon Markov model with seven health states was developed from the perspective of Scottish public healthcare providers. Model inputs for effectiveness, resource use, direct costs and utilities were obtained from published sources and a Scottish expert panel. The main model outcome was the incremental cost-effectiveness ratio (ICER), expressed as cost per quality-adjusted life year (QALY), for fidaxomicin versus vancomycin; ICERs were interpreted using willingness-to-pay thresholds of £20 000/QALY and £30 000/QALY. One-way and probabilistic sensitivity analyses were performed. Results Total costs were similar with fidaxomicin and vancomycin in patients with severe CDI (£14 515 and £14 344, respectively) and in patients with a first recurrence (£16 535 and £16 926, respectively). Improvements in clinical outcomes with fidaxomicin resulted in small QALY gains versus vancomycin (severe CDI, +0.010; patients with first recurrence, +0.019). Fidaxomicin was cost-effective in severe CDI (ICER £16 529/QALY) and dominant (i.e. more effective and less costly) in patients with a first recurrence. The probability that fidaxomicin was cost-effective at a willingness-to-pay threshold of £30 000/QALY was 60% for severe CDI and 68% in a first recurrence. Conclusions Fidaxomicin is cost-effective in patients with severe CDI and in patients with a first CDI recurrence versus vancomycin. PMID:25096079

Purpose: We designed this study to determine which patients have a high risk of supraclavicular node recurrence in N1 breast cancer previously treated with surgery but not having received supraclavicular radiation therapy (SCRT) and to identify which patients needed SCRT. Methods and Materials: We performed a retrospective review of 448 pathologic N1 breast cancer patients treated with mastectomy or breast-conserving treatment, but without SCRT, between 1994 and 2003. Mastectomy was performed in 302 patients (67.4%). The median number of axillary nodes dissected was 17 (range, 5-53). Systemic chemotherapy was administered in 443 patients (98.9%), and 144 patients received radiation aftermore » breast-conserving surgery. The median follow-up was 88 months (range, 15-170 months). Results: At follow-up, the treatment failed in 101 patients (22.5%), and 39 patients (8.7%) had supraclavicular node recurrence. Prognostic factors in supraclavicular node recurrence included lymphovascular invasion (p < 0.0001), extracapsular extension (p < 0.0001), the number of involved axillary nodes (p = 0.0003), and the level of involved axillary nodes (p = 0.012) in univariate and multivariate analyses. The total number of prognostic factors correlated well with supraclavicular node recurrence. In the analysis of 5-year supraclavicular node recurrence-free survival, patients with two or more factors showed a significantly higher recurrence rate than did patients with fewer than two factors (96.8% and 72.9%, respectively; p < 0.0001). Conclusions: The prognostic factors associated with supraclavicular node recurrence were lymphovascular invasion, extracapsular extension, and the number and level of involved axillary nodes. Patients with two or more prognostic factors might benefit from SCRT.« less

Significance of lobular intraepithelial neoplasia at margins of breast conservation specimens: a report of 38 cases and literature review

PubMed Central

2010-01-01

Background Presence of lobular intraepithelial neoplasia (LIN) is not routinely reported as part of margin assessment in breast conservation therapy (BCT) as in ductal carcinoma in situ (DCIS). With new emerging evidence of LIN as possible precursor lesion, the hypothesis is that LIN at the margin may increase the risk of local recurrence with BCT. The aim is to determine whether there is an increase incidence of recurrence when LIN is found at surgical margins on BCT. Methods We retrospectively reviewed a total of 1,334 BCT at a single institution in a 10 year period. Inclusion criteria are positive margin with LIN from primary BCT containing invasive and/or in situ carcinoma with comparison to the negative control group who had similar diseases with negative margin for LIN. Results We identified 38 cases (2.8%) with LIN either lobular carcinoma in situ/atypical lobular hyperplasia (LCIS/ALH) at a margin on initial BCT with 36% recurrence rate. Of the 38 cases: 5 (13%) were lost to follow-up, 12 (32%) had no further procedures performed and 21 (55%) had re-excision. Out of 21 patients who had re-excisions, 12 (57%) had residual invasive carcinoma or DCIS, three (14%) had pleomorphic LCIS and 4 (19%) showed residual classic type LCIS. 71% had significant residual disease (local recurrence) and 29% had no residual disease. A negative control group consisted of 38 cases. We found two patients with bone or brain metastasis and one local recurrence. Clinical follow up periods range from 1 to 109 months. Conclusions LIN found at a margin on BCT showed a significant recurrent ipsilateral disease. Our study supports the view that LIN seen at the margin may play a role in recurrence. PMID:20727142

Purpose Transsphenoidal surgery (TSS) is the primary treatment modality for Cushing’s disease (CD). However, the predictors of post-operative remission and recurrence remain debatable. Thus, we studied the post-operative remission and long-term recurrence rates, as well as their respective predictive factors. Methods A retrospective analysis of case records of 230 CD patients who underwent primary microscopic TSS at our tertiary care referral centre between 1987 and 2015 was undertaken. Demographic features, pre- and post-operative hormonal values, MRI findings, histopathological features and follow-up data were recorded. Remission and recurrence rates as well as their respective predictive factors were studied. Results Overall, the post-operative remission rate was 65.6% (early remission 46%; delayed remission 19.6%), while the recurrence rate was 41% at mean follow-up of 74 ± 61.1 months (12–270 months). Significantly higher early remission rates were observed in patients with microadenoma vs macroadenoma (51.7% vs 30.6%, P = 0.005) and those with unequivocal vs equivocal MRI for microadenoma (55.8% vs 38.5%, P = 0.007). Patients with invasive macroadenoma had poorer (4.5% vs 45%, P = 0.001) remission rates. Recurrence rates were higher in patients with delayed remission than those with early remission (61.5% vs 30.8%, P = 0.001). Duration of post-operative hypocortisolemia ≥13 months predicted sustained remission with 100% specificity and 46.4% sensitivity. Recurrence could be detected significantly earlier (27.7 vs 69.2 months, P < 0.001) in patients with available serial follow-up biochemistry as compared to those with infrequent follow-up after remission. Conclusion In our study, remission and recurrence rates were similar to that of reported literature, but proportion of delayed remission was relatively higher. Negative/equivocal MRI findings and presence of macroadenoma, especially those with cavernous sinus invasion were predictors of poor remission rates. In addition to early remission, longer duration of post-operative hypocortisolism is an important predictor of sustained remission. Regular biochemical surveillance may help in identifying recurrence early. PMID:28912338

Some 5%-15% of all women experience postpartum depression (PPD), which for many is their first psychiatric disorder. The purpose of this study was to estimate the incidence of postpartum affective disorder (AD), duration of treatment, and rate of subsequent postpartum AD and other affective episodes in a nationwide cohort of women with no prior psychiatric history. Linking information from several Danish national registers, we constructed a cohort of 457,317 primiparous mothers with first birth (and subsequent births) from 1 January 1996 to 31 December 2013 (a total of 789,068 births) and no prior psychiatric hospital contacts and/or use of antidepressants. These women were followed from 1 January 1996 to 31 December 2014. Postpartum AD was defined as use of antidepressants and/or hospital contact for PPD within 6 months after childbirth. The main outcome measures were risk of postpartum AD, duration of treatment, and recurrence risk. We observed 4,550 (0.6%) postpartum episodes of AD. The analyses of treatment duration showed that 1 year after the initiation of treatment for their first episode, 27.9% of women were still in treatment; after 4 years, 5.4%. The recurrence risk of postpartum AD for women with a PPD hospital contact after first birth was 55.4 per 100 person-years; for women with postpartum antidepressant medication after first birth, it was 35.0 per 100 person-years. The rate of postpartum AD after second birth for women with no history of postpartum AD was 1.2 per 100 person-years. After adjusting for year of birth and mother's age, women with PPD hospital contact after first birth had a 46.4 times higher rate (95% CI 31.5-68.4) and women with postpartum antidepressant medication after their first birth had a 26.9 times higher rate (95% CI 21.9-33.2) of a recurrent postpartum episode after their second birth compared to women with no postpartum AD history. Limitations include the use of registry data to identify cases and limited confounder control. In this study, an episode of postpartum AD was observed for 0.6% of childbirths among women with no prior psychiatric history. The observed episodes were characterized by a relatively short treatment duration, yet the women had a notably high rate of later AD and recurrent episodes of postpartum AD. The recurrence risk of postpartum AD was markedly higher among women with PPD hospital contact after first birth compared to women with postpartum antidepressant medication after first birth. Our results underline the necessity of measures targeted at specific vulnerable groups, such as women who experience PPD as a first psychiatric episode.

Acute biliary pancreatitis (ABP) is a severe complication of gallstone disease with considerable mortality, and its recurrence rate is reported as 50-90% for ABP patients who do not undergo cholecystectomy. However, the incidence of and risk factors for recurrent pancreatobiliary complications after the initial improvement of ABP are not well established in the literature. The aims of this study were to determine the risk factors for recurrent pancreatobiliary complications and to compare the outcomes between early (within 2 weeks after onset of pancreatitis) and delayed cholecystectomy in patients with ABP. Patients diagnosed with ABP at Yeungnam University Hospital from January 2004 to July 2016 were retrospectively reviewed. The following risk factors for recurrent pancreatobiliary complications (acute pancreatitis, acute cholecystitis, and acute cholangitis) were analyzed: demographic characteristics, laboratory data, size and number of gallstones, severity of pancreatitis, endoscopic sphincterotomy, and timing of cholecystectomy. Patients were categorized into two groups: patients with recurrent pancreatobiliary complications (Group A) and patients without pancreatobiliary complications (Group B). Of the total 290 patients with ABP (age 66.8 ± 16.0 years, male 47.9%), 56 (19.3%) patients developed recurrent pancreatobiliary complications, of which 35 cases were acute pancreatitis, 11 cases were acute cholecystitis, and 10 cases were acute cholangitis. Endoscopic sphincterotomy and cholecystectomy were performed in 134 (46.2%) patients and 95 (32.8%) patients, respectively. Age, sex, BMI, diabetes, number of stone, severity of pancreatitis, and laboratory data were not significantly correlated with recurrent pancreatobiliary complications. The risk of recurrent pancreatobiliary complications was significantly increased in the delayed cholecystectomy group compared with the early cholecystectomy group (45.5 vs. 5.0%, p < 0.001). Based on the multivariate logistic regression analyses, two factors, size of gallstone less than or equal to 5 mm and delayed cholecystectomy, were found as risk factors associated with recurrent pancreatobiliary complications. The incidence of recurrent pancreatobiliary complications was 19.3% and was significantly increased in patients with size of gallstone less than or equal to 5 mm and in those who underwent delayed cholecystectomy.

We compared the rates of upper tract imaging abnormalities of recurrent urinary tract infections due to bacterial persistence or reinfection. Following institutional review board approval we reviewed a prospectively maintained database of women with documented recurrent urinary tract infections (3 or more per year) and trigonitis. We searched for demographic data, urine culture findings and findings on radiology interpreted upper tract imaging, including renal ultrasound, computerized tomography or excretory urogram. Patients with irretrievable images, absent or incomplete urine culture results for review, no imaging performed, an obvious source of recurrent urinary tract infections or a history of pyelonephritis were excluded from analysis. Of 289 women from 2006 to 2014 with symptomatic recurrent urinary tract infections 116 met study inclusion criteria. Mean ± SD age was 65.0 ± 14.4 years. Of the women 95% were white and 81% were postmenopausal. Almost a third were sexually active and none had prolapse stage 2 or greater. Of the 116 women 48 (41%) had persistent and 68 (59%) had reinfection recurrent urinary tract infection. Imaging included ultrasound in 52 patients, computerized tomography in 26, ultrasound and computerized tomography in 31, and excretory urogram with ultrasound/computerized tomography in 7. Of the total of 58 imaging findings in 55 women 57 (98%) were noncontributory. One case (0.9%) of mild hydronephrosis was noted in the persistent recurrent urinary tract infection group but it was not related to any clinical parameters. Escherichia coli was the dominant bacteria in 71% of persistent and 47% of reinfection recurrent urinary tract infections in the most recently reported urine culture. This study reaffirms that upper tract imaging is not indicated for bacterial reinfection, recurrent urinary tract infections. However, the same conclusion can be extended to recurrent urinary tract infections secondary to bacterial persistence, thus, questioning the routine practice of upper tract studies in white postmenopausal women with recurrent urinary tract infections and trigonitis.

Umbilical hernia repair is one of the most commonly performed general surgical procedures. However, there is little consensus about the factors that lead to umbilical hernia recurrence. To better understand the factors associated with long-term umbilical hernia recurrence. A retrospective cohort of 332 military veteran patients who underwent umbilical hernia repair was studied between January 1, 1998, and December 31, 2008, at the VA Boston Healthcare System. Recurrence and mortality outcomes were tracked from that period until June 1, 2014. Data were collected on patient characteristics, operative, and postoperative factors and univariate and multivariable analyses were used to assess which factors were significantly associated with umbilical hernia recurrence and mortality. All patients with primary umbilical hernia repair, with or without a concurrent unrelated procedure, were included in the study. Patients excluded were those who underwent umbilical hernia repair as a part of another major planned procedure with abdominal incisions. Data were collected from June 1, 2014, to November 1, 2015. Statistical analysis was performed from November 2, 2015, to April 1, 2016. The primary study outcomes were umbilical hernia recurrence and death. Of the 332 patients in this study, 321 (96.7%) were male, mean age was 58.4 years, and mean (SD) time of follow-up was 8.5 (4.1) years. The hernia recurrence rate was 6.0% (n = 20) at a mean 3.1 years after index repair (median, 1.0-year; range, 0.33-13 years). The primary suture repair recurrence rate was 9.8% (16 of 163 patients), and the mesh repair recurrence rate was 2.4% (4 of 169 patients). On univariate analysis, ascites (P = .02), liver disease (P = .02), diabetes (P = .04), and primary suture (nonmesh) repairs (P = .04) were significantly associated with increased recurrence rates. Patients who had a history of hernias (125 [39%]) were less likely to have umbilical hernia recurrences (χ21 = 4.65, P = .03). On multivariable regression analysis, obesity and ascites were associated with significantly increased odds ratios of recurrence of 3.3 (95% CI, 1.0-10.1) and 8.0 (95% CI, 1.8-34.4), respectively. Mesh repair was seen to decrease recurrence with odds of 0.28 (95% CI, 0.08-0.95). There was no significant difference in complication rates between mesh repair and primary suture repair. The survival rate was 73% (n = 242) at the end of the study. Factors associated with mortality were older age, smoking, liver disease, ascites, emergency or semiurgent repair, and need for intraoperative bowel resection. Ascites, liver disease, diabetes, obesity, and primary suture repair without mesh are associated with increased umbilical hernia recurrence rates. Elective umbilical hernia repair with mesh should be considered in patients with multiple comorbidities given that the use of mesh offers protection from recurrence without major morbidity.

Importance Umbilical hernia repair is one of the most commonly performed general surgical procedures. However, there is little consensus about the factors that lead to umbilical hernia recurrence. Objective To better understand the factors associated with long-term umbilical hernia recurrence. Design, Setting, and Participants A retrospective cohort of 332 military veteran patients who underwent umbilical hernia repair was studied between January 1, 1998, and December 31, 2008, at the VA Boston Healthcare System. Recurrence and mortality outcomes were tracked from that period until June 1, 2014. Data were collected on patient characteristics, operative, and postoperative factors and univariate and multivariable analyses were used to assess which factors were significantly associated with umbilical hernia recurrence and mortality. All patients with primary umbilical hernia repair, with or without a concurrent unrelated procedure, were included in the study. Patients excluded were those who underwent umbilical hernia repair as a part of another major planned procedure with abdominal incisions. Data were collected from June 1, 2014, to November 1, 2015. Statistical analysis was performed from November 2, 2015, to April 1, 2016. Main Outcomes and Measures The primary study outcomes were umbilical hernia recurrence and death. Results Of the 332 patients in this study, 321 (96.7%) were male, mean age was 58.4 years, and mean (SD) time of follow-up was 8.5 (4.1) years. The hernia recurrence rate was 6.0% (n = 20) at a mean 3.1 years after index repair (median, 1.0-year; range, 0.33-13 years). The primary suture repair recurrence rate was 9.8% (16 of 163 patients), and the mesh repair recurrence rate was 2.4% (4 of 169 patients). On univariate analysis, ascites (P = .02), liver disease (P = .02), diabetes (P = .04), and primary suture (nonmesh) repairs (P = .04) were significantly associated with increased recurrence rates. Patients who had a history of hernias (125 [39%]) were less likely to have umbilical hernia recurrences (χ21 = 4.65, P = .03). On multivariable regression analysis, obesity and ascites were associated with significantly increased odds ratios of recurrence of 3.3 (95% CI, 1.0-10.1) and 8.0 (95% CI, 1.8-34.4), respectively. Mesh repair was seen to decrease recurrence with odds of 0.28 (95% CI, 0.08-0.95). There was no significant difference in complication rates between mesh repair and primary suture repair. The survival rate was 73% (n = 242) at the end of the study. Factors associated with mortality were older age, smoking, liver disease, ascites, emergency or semiurgent repair, and need for intraoperative bowel resection. Conclusions and Relevance Ascites, liver disease, diabetes, obesity, and primary suture repair without mesh are associated with increased umbilical hernia recurrence rates. Elective umbilical hernia repair with mesh should be considered in patients with multiple comorbidities given that the use of mesh offers protection from recurrence without major morbidity.
