The aim of this study was to identify risk factors related with failure of conservative management of adhesive small bowel obstruction (ASBO) in patients with previous colorectal surgery. Patients admitted with the diagnosis of ASBO after previous colorectal resection, were included. All patients underwent administration of Gastrografin®. Abdominal radiography was done after 24 h, to confirm the presence of contrast in colon (incomplete obstruction) or not (complete obstruction). Several factors were investigated to study their relationship with the failure of conservative management. Failure of conservative management was considered when emergency operation was needed to solve ASBO. Incomplete obstruction was observed in 174 episodes (93.0%) while in 13 (7.0%) was complete. One hundred seventy-one ASBO episodes (91.4%) responded successfully to nonoperative treatment and 16 (8.6%) required emergency surgery. Five patients needed bowel resection. Results on the diagnostic test with Gastrografin® showed a sensitivity of 75%, specificity of 99%, positive predictive value 92%, and negative predictive value 98%. Age over 75 years was the only predictive factor for failure of conservative management. The median waiting time from the radiologic confirmation of complete obstruction to surgery was higher in patients requiring bowel resection when compared to those who did not need resection. The use of Gastrografin® in ASBO after colorectal resection is a safe and useful tool for the indication of conservative management. Age over 75 years is a predictive factor for need of surgery. Surgery should be performed no later than the following 24 h of confirmed complete obstruction.

The treatment of breast cancer involves a multi-disciplinary approach with radiation therapy playing a key role. Breast-conserving surgery has been an option for women with early-stage breast cancer for over two decades now. Multiple randomized trials now have demonstrated the efficacy of breast-conserving surgery followed by radiation therapy. With the advancements in breast imaging and the successful campaign for early detection of breast cancer, more women today are found to have early-stage small breast cancers. Patient factors (breast size, tumor location, history of prior radiation therapy, preexisting conditions such as collagen vascular disease, age, having prosthetically augmented breasts), pathological factors (margin status, tumor size, presence of extensive intraductal component requiring multiple surgical excisions), as well as patient preference are all taken into consideration prior to surgical management of breast cancer. Whole-breast fractionated radiation therapy between 5 and 7 weeks is considered as the standard of care treatment following breast-conserving surgery. However, new radiation treatment strategies have been developed in recent years to provide alternatives to the conventional 5-7 week whole-breast radiation therapy for some patients. Accelerated partial breast radiation therapy (APBI) was introduced because the frequency of breast recurrences outside of the surgical cavity has been shown to be low. This technique allows treatments to be delivered quicker (usually 1 week, twice daily) to a limited volume. Often times, this treatment involves the use of a brachytherapy applicator to be placed into the surgical cavity following breast-conserving surgery. Accelerated hypofractionated whole-breast irradiation may be another faster way to deliver radiation therapy following breast-conserving surgery. This journal article reviews the role of radiation therapy in women with early-stage breast cancer addressing patient selection in breast-conserving therapy, a review of pertinent trials in breast-conserving therapy, as well as the different treatment techniques available to women following breast-conserving surgery.

Objective To assess the therapeutic value of Gastrografin in the management of adhesive small bowel obstruction after unsuccessful conservative treatment. Summary Background Data Gastrografin is a hyperosmolar water-soluble contrast medium. Besides its predictive value for the need for surgery, there is probably a therapeutic role of this contrast medium in adhesive small bowel obstruction. Methods Patients with clinical evidence of adhesive small bowel obstruction were given trial conservative treatment unless there was suspicion of strangulation. Those who responded in the initial 48 hours had conservative treatment continued. Patients showing no clinical and radiologic improvement in the initial 48 hours were randomized to undergo either Gastrografin meal and follow-through study or surgery. Contrast that appeared in the large bowel within 24 hours was regarded as a partial obstruction, and conservative treatment was continued. Patients in whom contrast failed to reach the large bowel within 24 hours were considered to have complete obstruction, and laparotomy was performed. For patients who had conservative treatment for more than 48 hours with or without Gastrografin, surgery was performed when there was no continuing improvement. Results One hundred twenty-four patients with a total of 139 episodes of adhesive obstruction were included. Three patients underwent surgery soon after admission for suspected bowel strangulation. Strangulating obstruction was confirmed in two patients. One hundred one obstructive episodes showed improvement in the initial 48 hours and conservative treatment was continued. Only one patient required surgical treatment subsequently after conservative treatment for 6 days. Thirty-five patients showed no improvement within 48 hours. Nineteen patients were randomized to undergo Gastrografin meal and follow-through study and 16 patients to surgery. Gastrografin study revealed partial obstruction in 14 patients. Obstruction resolved subsequently in all of them after a mean of 41 hours. The other five patients underwent laparotomy because the contrast study showed complete obstruction. The use of Gastrografin significantly reduced the need for surgery by 74%. There was no complication that could be attributed to the use of Gastrografin. No strangulation of bowel occurred in either group. Conclusions The use of Gastrografin in adhesive small bowel obstruction is safe and reduces the need for surgery when conservative treatment fails.

The management of peptic ulcers has dramatically changed and the incidence of elective surgery for gastroduodenal peptic ulcers has markedly decreased; hence, the incidence of emergency surgery for perforated peptic ulcers has slightly increased. In select cases, conservative therapy can be used as an alternative for treating perforated gastroduodenal ulcers. In this study, we evaluated the efficacy of percutaneous abdominal drainage for the conservative treatment of perforated gastroduodenal ulcers. We retrospectively studied 51 patients who had undergone conservative therapy for perforated gastroduodenal ulcers. These patients were divided into 2 groups on the basis of the initial treatment with conservative therapy with or without percutaneous drainage: group PD included patients who had undergone percutaneous drainage and group NPD, patients who had undergone non-percutaneous drainage. In the PD group, 14.3% (n=3) of the patients did not respond to conservative therapy, while this value was 43.3% (n=13) in the NPD group. The 2 groups differed significantly with respect to conversion from conservative therapy to surgery (p<0.0352). Conservative therapy for perforated gastroduodenal ulcers should be performed only in the case of patients meeting the required criteria; its combination with percutaneous intraperitoneal drainage is effective as initial conservative therapy.

Conservative breast cancer surgery is facing a new problem: the potential tumour involvement of resection margins. This eventuality has been closely and negatively associated with disease-free survival. Various factors may influence the likelihood of margins being affected, mostly related to the characteristics of the tumour, patient or surgical technique. In the last decade, many studies have attempted to find predictive factors for margin involvement. However, it is currently the new techniques used in the study of margins and tumour localisation that are significantly reducing reoperations in conservative breast cancer surgery.

The aim of this study is to assess the outcome of conservative management of infected mesh grafts following abdominal wall hernia repair. This study retrospectively examined the charts of patients who developed mesh-site infection following surgery for abdominal hernia repair to determine how effective conservative management in the form of antibiotics and wound management was on the resolution of infection and wound healing. Over a period of 30 months, 13 patients developed infected mesh grafts post-hernia repair surgery. Twelve patients were successfully treated conservatively with local wound care and antibiotics if clinically indicated. One patient returned to theatre to have the infected mesh removed. Of the patients that healed eleven were treated with negative pressure wound therapy (VAC(®)). This series of case studies indicate that conservative management of abdominal wall-infected hernia mesh cases is likely to be successful.

There is scarce knowledge of physical function and pain due to multiple rib fractures following trauma. The purpose of this follow-up was to assess respiratory and physical function, pain, range of movement and kinesiophobia in patients with multiple rib fractures who had undergone stabilizing surgery and compare with conservatively managed patients. A consecutive series of 31 patients with multiple rib fractures who had undergone stabilizing surgery were assessed >1 year after the trauma concerning respiratory and physical function, pain, range of movement in the shoulders and thorax, shoulder function and kinesiophobia. For comparison, 30 patients who were treated conservatively were evaluated with the same outcome measures. The results concerning pain, lung function, shoulder function and level of physical activity were similar in the two groups. The patients who had undergone surgery had a significantly larger range of motion in the thorax (p < 0.01) and less deterioration in two items in Disability Rating Index (sitting and standing bent over a sink) (p < 0.05). It is questionable whether the control group is representative since the majority of patients were invited but refused to participate in the follow-up. In addition, this study is too small to make a definitive conclusion if surgery is better than conservative treatment. But we see some indications, such as a tendency for decreased pain, better thoracic range of motion and physical function which would indicate that surgery is preferable. If operation technique could improve in the future with a less invasive approach, it would presumably decrease post-operative pain and the benefit of surgery would be greater than the morbidity of surgery. Patients undergoing surgery have a similar long-term recovery to those who are treated conservatively except for a better range of motion in the thorax and fewer limitations in physical function. Surgery seems to be beneficial for some patients, the question remains which patients. FoU i Sverige (R&D in Sweden), No 106121.

Is there a difference in functional outcome between conservative versus radical rectal surgery in patients with large deep endometriosis infiltrating the rectum 2 years postoperatively? No evidence was found that functional outcomes differed when conservative surgery was compared to radical rectal surgery for deeply invasive endometriosis involving the bowel. Adopting a conservative approach to the surgical management of deep endometriosis infiltrating the rectum, by employing shaving or disc excision, appears to yield improved digestive functional outcomes. However, previous comparative studies were not randomized, introducing a possible bias regarding the presumed superiority of conservative techniques due to the inclusion of patients with more severe deep endometriosis who underwent colorectal resection. From March 2011 to August 2013, we performed a 2-arm randomized trial, enroling 60 patients with deep endometriosis infiltrating the rectum up to 15 cm from the anus, measuring more than 20 mm in length, involving at least the muscular layer in depth and up to 50% of rectal circumference. No women were lost to follow-up. Patients were enroled in three French university hospitals and had either conservative surgery, by shaving or disc excision, or radical rectal surgery, by segmental resection. Randomization was performed preoperatively using sequentially numbered, opaque, sealed envelopes, and patients were informed of the results of randomization. The primary endpoint was the proportion of patients experiencing one of the following symptoms: constipation (1 stool/>5 consecutive days), frequent bowel movements (≥3 stools/day), defecation pain, anal incontinence, dysuria or bladder atony requiring self-catheterization 24 months postoperatively. Secondary endpoints were the values of the Visual Analog Scale (VAS), Knowles-Eccersley-Scott-Symptom Questionnaire (KESS), the Gastrointestinal Quality of Life Index (GIQLI), the Wexner scale, the Urinary Symptom Profile (USP) and the Short Form 36 Health Survey (SF36). A total of 60 patients were enroled. Among the 27 patients in the conservative surgery arm, two were converted to segmental resection (7.4%). In each group, 13 presented with at least one functional problem at 24 months after surgery (48.1 versus 39.4%, OR = 0.70, 95% CI 0.22-2.21). The intention-to-treat comparison of the overall scores on KESS, GIQLI, Wexner, USP and SF36 did not reveal significant differences between the two arms. Segmental resection was associated with a significant risk of bowel stenosis. The inclusion of only large infiltrations of the rectum does not allow the extrapolation of conclusions to small nodules of <20 mm in length. The presumption of a 40% difference favourable to conservative surgery in terms of postoperative functional outcomes resulted in a lack of power to demonstrate a difference for the primary endpoint. Conservative surgery is feasible in patients managed for large deep rectal endometriosis. The trial does not show a statistically significant superiority of conservative surgery for mid-term functional digestive and urinary outcomes in this specific population of women with large involvement of the rectum. There is a higher risk of rectal stenosis after segmental resection, requiring additional endoscopic or surgical procedures.

It is considered that a regimen combining pharmacologic management and lifestyle modifications is the most effective treatment for laryngeal granulomas caused by GER. This study compared the results of the combination therapy and surgery to determine the best treatment of laryngeal granuloma caused by gastro-esophageal reflux in 51 patients. Prospective study. In the conservative treatment group, the CR rate was 89.7% and recurrence rate was 2.6%, while the lesions remained in patients (7.7%). This study compared the CR and recurrence rates between conservative treatment and surgery for granuloma. The results showed that the laryngeal granuloma recurrence rate was significantly lower with the conservative treatment regimen compared with surgery (p = .0016).

In children with Prader Willi syndrome (PWS), besides growth hormone (GH) therapy, control of the food environment and regular exercise, surgical treatment of scoliosis deformities seems the treatment of choice, even though the risks of spinal surgery in this specific population is very high. Therefore the question arises as to whether the risks of spinal surgery outweigh the benefits in a condition, which bears significant risks per se. The purpose of this systematic review of the Pub Med literature was to find mid or long-term results of spinal fusion surgery in patients with PWS, and to present the conservative treatment in a case study of nine patients with this condition. Types of studies included; all kinds of studies; retrospective and prospective ones, which reported upon the outcome of scoliosis surgery in patients with PWS.Types of participants included: patients with scoliosis and PWS.Type of intervention: surgery.Search strategy for identification of the studies; Pub Med; limited to English language and bibliographies of all reviewed articles.Nine patients with PWS from our data-base treated conservatively have been found, being 19 years or over at the time this study has been performed. The results of conservative management are described and related to the natural history and treatment results found in the Pub Med review. From 2210 titles displayed in the Pub Med database with the key word being "Prader Willi syndrome", 5 different papers were displayed at the date of the search containing some information on the outcome of surgery and none appeared to contain a mid or long-term follow-up. The PWS patients treated conservatively from our series all stayed below 70 degrees and some of which improved. If the curve of scoliosis patients with PWS can be kept within certain limits (usually below 70 degrees) conservatively, this treatment seems to have fewer complications than surgical treatments. The results of our retrospective study of nine patients demonstrate that scoliosis in this entity plays only a minor role and surgery is unnecessary when high quality conservative management exists. There is lack of the long follow-up studies in post-surgical cases in patients with PWS and scoliosis. The rate of complications of spinal fusion in patients with PWS and scoliosis is very high and the death rates have been found to be higher than in patients with Adolescent Idiopathic Scoliosis (AIS). The long-term side-effects of the intervention are detrimental, so that the risk-benefit ratio favours the conservative approaches over spinal fusion surgery.

Ultrasound-guided breast-sparing surgery to improve cosmetic outcomes and quality of life. A prospective multicentre randomised controlled clinical trial comparing ultrasound-guided surgery to traditional palpation-guided surgery (COBALT trial)

PubMed Central

2011-01-01

Background Breast-conserving surgery for breast cancer was developed as a method to preserve healthy breast tissue, thereby improving cosmetic outcomes. Thus far, the primary aim of breast-conserving surgery has been the achievement of tumour-free resection margins and prevention of local recurrence, whereas the cosmetic outcome has been considered less important. Large studies have reported poor cosmetic outcomes in 20-40% of patients after breast-conserving surgery, with the volume of the resected breast tissue being the major determinant. There is clear evidence for the efficacy of ultrasonography in the resection of nonpalpable tumours. Surgical resection of palpable breast cancer is performed with guidance by intra-operative palpation. These palpation-guided excisions often result in an unnecessarily wide resection of adjacent healthy breast tissue, while the rate of tumour-involved resection margins is still high. It is hypothesised that the use of intra-operative ultrasonography in the excision of palpable breast cancer will improve the ability to spare healthy breast tissue while maintaining or even improving the oncological margin status. The aim of this study is to compare ultrasound-guided surgery for palpable tumours with the standard palpation-guided surgery in terms of the extent of healthy breast tissue resection, the percentage of tumour-free margins, cosmetic outcomes and quality of life. Methods/design In this prospective multicentre randomised controlled clinical trial, 120 women who have been diagnosed with palpable early-stage (T1-2N0-1) primary invasive breast cancer and deemed suitable for breast-conserving surgery will be randomised between ultrasound-guided surgery and palpation-guided surgery. With this sample size, an expected 20% reduction of resected breast tissue and an 18% difference in tumour-free margins can be detected with a power of 80%. Secondary endpoints include cosmetic outcomes and quality of life. The rationale, study design and planned analyses are described. Conclusion The COBALT trial is a prospective, multicentre, randomised controlled study to assess the efficacy of ultrasound-guided breast-conserving surgery in patients with palpable early-stage primary invasive breast cancer in terms of the sparing of breast tissue, oncological margin status, cosmetic outcomes and quality of life.

We present the case of a 39-year-old man who presented with hoarseness and progressively worsening dyspnea. Findings on laryngoscopy and computed tomography strongly suggested the presence of a chondrosarcoma. The patient underwent open surgery for removal of the lesion with wide margins. Reconstruction was carried out with two segments of costal cartilage. Laryngeal chondrosarcomas are rare, malignant, usually well-differentiated neoplasms that should be treated with conservative surgery. Recurrences should be treated more aggressively.

Disagreement exists over the ability of different diagnostic tests to define obstruction, indications and timing of surgery and which patients will benefit from surgical intervention in antenatal hydronephrosis (ANH) due to ureteropelvic junction obstruction (UPJO). We try to find a way to predict which patients of ANH due to UPJO will eventually need surgery during conservative management. Prospective single centre study involving 122 renal units at a referral centre in India. Patients on conservative management were followed using a standard protocol and operated for pre-defined indications defining failure of conservative management. Patients who underwent surgery were compared with the non-operated group in terms of sex, side, baseline grade of hydronephrosis, maximum anterioposterior diameter on first postnatal ultrasound and differential renal function on first renal scan. A total of 109 renal units qualified for conservative management. Of those, 23.9% required operative intervention during follow-up. Median time to failure of conservative management was 37 weeks. The median follow-up of non-operated cases was 54 months. Univariate analysis revealed that society of fetal urology (SFU) grade of hydronephrosis, anteroposterior diameter (APD), cortical thickness (CT), and pre-operative differential renal function (DRF) had a significant association with surgery (P < 0.05). Multivariate analysis revealed APD and pre-operative DRF as the only independent predictors for requiring surgery, while CT and initial SFU grade of hydronephrosis were not. Receiver operating curve analysis showed that an APD of 24.3 mm could predict the need for surgery, with a sensitivity of 73.1% and a specificity of 88.0%. APD and DRF are the predictive factors for surgery. We stop short of recommending surgery only on the basis of APD. Instead we recommend that efforts be made to improve the specificity of this criterion, or by using APD in perspective with the differential renal function. We can reduce the burden of investigations in those with APD <24 mm while those with APD >24 mm can be more comprehensively monitored. Copyright © 2015 Journal of Pediatric Urology Company.

Ultrasound-guided breast-conserving surgery (USS) results in a significant reduction in both margin involvement and excision volumes (COBALT trial). Objective. The aim of the present study was to determine whether USS also leads to improvements in cosmetic outcome and patient satisfaction when compared with standard palpation-guided surgery (PGS). A total of 134 patients with T1–T2 invasive breast cancer were included in the COBALT trial (NTR2579) and randomized to either USS (65 patients) or PGS (69 patients). Cosmetic outcomes were assessed by a three-member panel using computerized software Breast Cancer Conservative Treatment cosmetic results (BCCT.- core) and by patient self-evaluation, including patient satisfaction. Time points for follow-up were 3, 6, and 12 months after surgery. Overall cosmetic outcome and patient satisfaction were scored on a 4-point Likert scale (excellent, good, fair, or poor), and outcomes were analyzed using a multilevel, mixed effect, proportional odds model for ordinal responses. Ultrasound-guided breast-conserving surgery achieved better cosmetic outcomes, with 20 % excellence overall and only 6 % rated as poor, whereas 14 % of PGS outcomes were rated excellent and 13 % as poor. USS also had consistently lower odds for worse cosmetic outcomes (odds ratio 0.55, p = 0.067) than PGS. The chance of having a worse outcome was significantly increased by a larger lumpectomy volume (ptrend = 0.002); a volume [40 cc showed odds 2.78-fold higher for a worse outcome than a volume B40 cc. USS resulted in higher patient satisfaction compared with PGS. Ultrasound-guided breast-conserving surgery achieved better overall cosmetic outcomes and patient satisfaction than PGS. Lumpectomy volumes[40 cc resulted in significantly worse cosmetic outcomes.

The Brain Trauma Foundation has published guidelines on the surgical management of traumatic subdural hematoma (SDH). However, no data exist on the proportion of patients with SDH that can be selected for conservative management and what is the outcome of these patients. The goals of this study were as follows: 1) to establish what proportion of patients are initially treated conservatively; 2) to determine what proportion of patients will deteriorate and require surgical evacuation; and 3) to identify risk factors associated with deterioration and delayed surgery. All cases of acute traumatic SDH (869 when inclusion criteria were met) presenting over a 4-year period were reviewed. For all conservatively treated SDH, the proportion of delayed surgical intervention and the Glasgow Outcome Scale score were taken as outcome measures. Multiple factors were compared between patients who required delayed surgery and patients without surgery. Of the 869 patients with acute traumatic SDH, 646 (74.3%) were initially treated conservatively. A good outcome was achieved in 76.7% of the patients. Only 6.5% eventually required delayed surgery, and the median delay for surgery was 9.5 days. Factors associated with deterioration were as follows: 1) thicker SDH (p<0.001); 2) greater midline shift (p<0.001); 3) location at the convexity (p=0.001); 4) alcohol abuse (p=0.0260); and 5) history of falls (p=0.018). There was no significant difference in regard to age, sex, Glasgow Coma Scale score, Injury Severity Score, abnormal coagulation, use of blood thinners, and presence of cerebral atrophy or white matter disease. The majority of patients with SDH are treated conservatively. Of those, only 6.5% later required surgery, for raised intracranial pressure or SDH progression. Patients at risk can be identified and followed more carefully.

The epidemiology of Achilles tendon ruptures and treatment strategies have undergone a major change in recent years. We investigated the incidence of acute Achilles tendon ruptures, the choice of treatment strategies and treatment implementation. The research material consisted of patients living in the catchment area of Central Finland Hospital District who had been diagnosed with an acute Achilles tendon rupture between 2010 and 2015. The final sample consisted of 266 patients. Conservative treatment was started for 207 patients, and the remaining 59 were referred for surgery. During the study period, the proportion of patients undergoing surgery fell from 41% to 10%. Three patients (1.4%) were referred for surgery during conservative treatment, and 10 patients (4.7%) developed deep vein thrombosis while wearing a cast or an orthosis. Twelve patients (5.8%) sustained a re-rupture after conservative treatment. Two surgically-treated patients (3.5%) sustained a re-rupture, and one patient (1.7%) developed deep vein thrombosis. The strategies for treating acute Achilles tendon ruptures have clearly become more conservative in our hospital. Conservative treatment is safe and rarely fails. However, it is important to bear in mind that surgery still has a role in the treatment of acute Achilles tendon ruptures.

Women with pelvic organ prolapse (POP) and stress urinary incontinence (SUI) frequently undergo more than one treatment prior to settling on their final strategy. We hypothesize that women who are younger, with worse POP and SUI symptoms will desire and choose surgical treatment. A retrospective cohort study was performed over 1 year identifying new patients presenting with POP and/or SUI at a university hospital. Our aim was to determine patient desire for either surgical or conservative treatment, as well as the actual treatment chosen and received after the first visit and 1 year later. To identify predictors of choice, baseline demographic characteristics were obtained. Of the 203 women who met the inclusion criteria, 44.3 % (90/203) desired surgery and 55.7 % (113/203) desired conservative treatment at their first visit. Women who desired surgery were more likely to be younger (p = 0.003), sexually active (p = 0.001), have more advanced prolapse (p = 0.006), and have more bothersome symptoms (p = 0.05). Of the women who desired surgery at their first visit, 12.2 % (11/90) actually chose conservative treatment. These women were less likely to be insured (p = 0.01). By 1 year, of the women who initially desired and subsequently chose conservative treatment, 26.5 % (30/113) had undergone surgery. The women who changed from conservative to surgical treatment were more likely to be younger (p = 0.01), non-White (p = 0.03), and sexually active (p = 0.04). In this study, younger, sexually active women were more likely to either opt for surgery initially or to change their treatment plan from conservative to surgical.

Abstract STUDY QUESTION Is there a difference in functional outcome between conservative versus radical rectal surgery in patients with large deep endometriosis infiltrating the rectum 2 years postoperatively? SUMMARY ANSWER No evidence was found that functional outcomes differed when conservative surgery was compared to radical rectal surgery for deeply invasive endometriosis involving the bowel. WHAT IS KNOWN ALREADY Adopting a conservative approach to the surgical management of deep endometriosis infiltrating the rectum, by employing shaving or disc excision, appears to yield improved digestive functional outcomes. However, previous comparative studies were not randomized, introducing a possible bias regarding the presumed superiority of conservative techniques due to the inclusion of patients with more severe deep endometriosis who underwent colorectal resection. STUDY DESIGN SIZE, DURATION From March 2011 to August 2013, we performed a 2-arm randomized trial, enroling 60 patients with deep endometriosis infiltrating the rectum up to 15 cm from the anus, measuring more than 20 mm in length, involving at least the muscular layer in depth and up to 50% of rectal circumference. No women were lost to follow-up. PARTICIPANTS/MATERIALS, SETTING, METHODS Patients were enroled in three French university hospitals and had either conservative surgery, by shaving or disc excision, or radical rectal surgery, by segmental resection. Randomization was performed preoperatively using sequentially numbered, opaque, sealed envelopes, and patients were informed of the results of randomization. The primary endpoint was the proportion of patients experiencing one of the following symptoms: constipation (1 stool/>5 consecutive days), frequent bowel movements (≥3 stools/day), defecation pain, anal incontinence, dysuria or bladder atony requiring self-catheterization 24 months postoperatively. Secondary endpoints were the values of the Visual Analog Scale (VAS), Knowles–Eccersley–Scott-Symptom Questionnaire (KESS), the Gastrointestinal Quality of Life Index (GIQLI), the Wexner scale, the Urinary Symptom Profile (USP) and the Short Form 36 Health Survey (SF36). MAIN RESULTS AND THE ROLE OF CHANCE A total of 60 patients were enroled. Among the 27 patients in the conservative surgery arm, two were converted to segmental resection (7.4%). In each group, 13 presented with at least one functional problem at 24 months after surgery (48.1 versus 39.4%, OR = 0.70, 95% CI 0.22–2.21). The intention-to-treat comparison of the overall scores on KESS, GIQLI, Wexner, USP and SF36 did not reveal significant differences between the two arms. Segmental resection was associated with a significant risk of bowel stenosis. LIMITATIONS REASONS FOR CAUTION The inclusion of only large infiltrations of the rectum does not allow the extrapolation of conclusions to small nodules of <20 mm in length. The presumption of a 40% difference favourable to conservative surgery in terms of postoperative functional outcomes resulted in a lack of power to demonstrate a difference for the primary endpoint. WIDER IMPLICATIONS OF THE FINDINGS Conservative surgery is feasible in patients managed for large deep rectal endometriosis. The trial does not show a statistically significant superiority of conservative surgery for mid-term functional digestive and urinary outcomes in this specific population of women with large involvement of the rectum. There is a higher risk of rectal stenosis after segmental resection, requiring additional endoscopic or surgical procedures.

Most regional anesthesia in breast surgeries is performed as postoperative pain management under general anesthesia, and not as the primary anesthesia. Regional anesthesia has very few cardiovascular or pulmonary side-effects, as compared with general anesthesia. Pectoral nerve block is a relatively new technique, with fewer complications than other regional anesthesia. We performed Pecs I and Pec II block simultaneously as primary anesthesia under moderate sedation with dexmedetomidine for breast conserving surgery in a 49-year-old female patient with invasive ductal carcinoma. Block was uneventful and showed no complications. Thus, Pecs block with sedation could be an alternative to general anesthesia for breast surgeries.

Local flaps are a group of surgical procedures that can solve the thoracic closure of large defects after breast cancer surgery with low morbidity. Its use in skin necrosis complications after conservative surgery or skin sparing mastectomies facilitates the initiation of adjuvant treatments and reduces delays in this patient group. This article describes the anatomical basis for the planning of thoracic and abdominal local flaps. Also, the application of these local flaps for closing large defects in the chest and selective flaps for skin coverage by necrosis in breast conserving surgery. Copyright © 2016 AEC.

To investigate the effectiveness of cryoprecipitate in the comprehensive conservative therapy of patients with acute purulent pyelonephritis. We conducted a retrospective analysis of medical records of patients who were diagnosed with acute non-obstructive pyelonephritis from 2007to 2015. During this period, a total of 3912 patients with acute non-obstructive pyelonephritis were treated at the Department of Urology. Patients were assigned to either receive or not receive cryoprecipitate in the comprehensive conservative therapy. The comprehensive conservative therapy of both groups included antibacterial agents, detoxification, anti-inflammatory therapy. In the study group, patients received additional treatment with cryoprecipitate. By that way we estimated the number of patients who avoided surgery in both groups. There were 3912 patients divided into two groups. The first group included 756 patients (19.3%) who received cryoprecipitate in the comprehensive therapy of pyelonephritis. Of them, 735 patients (97.3%) did not require surgical treatment, and only 21 patients (2.7%) underwent surgery. The second group comprised 3156 patients (80.7%) who did not receive cryoprecipitate. Of them, 2974 patients (94.2%) were treated conservatively without surgical intervention and 182 patients (5.8%) received conservative therapy concurrently with surgical treatment. Therefore, including cryoprecipitate in the comprehensive conservative therapy of acute non-obstructive pyelonephritis results in twice smaller percentage of patients (2.7% vs 5.8%) requiring surgery compared to the comprehensive conservative therapy alone.

The Role of Oncoplastic Breast Surgery in Breast Cancer Treatment

The aim of this study is to discuss indications, advantages, disadvantages, oncologic and aesthetic results of Oncoplastic Surgery (OBS). Pubmed and Medline database were searched for articles published between 1998 and 2014 for keywords: oncoplastic breast surgery, therapeutic mammoplasty, oncoplastic breast reduction, synchrenous reconstructions. Role of OBS in breast cancer surgery, its aspects to be considered, its value and results have been interpreted. This technique has advantages by providing more extensive tumourectomy, yielding better aesthetic results compared with breast conserving surgery, allowing oncoplastic reduction in breast cancer patients with macromastia, with higher patient satisfaction and quality of life and by being inexpensive due to single session practice. As for its disadvantages are: re-excision is more difficult, risk for mastectomy is higher, it is depent on the Surgeron’s experience, it has a risk for delay in adjuvant therapies and its requirement for additional imaging studies during management. Main indications are patients with small tumour/breast volume, macromastia, multifocality, procedures which can disrupt breast cosmesis such as surgeries for upper inner breas tquadrient tumours. Contraindications are positive margin problems after wide excision, diffuse malign microcalsifications, inflammatory breast cancer, history of radiotherapy and patients’ preferences. Despite low evidence level, Oncoplastic Breast Surgery seems to be both reliable and acceptable in terms of oncologic and aesthetic aspects. Oncoplastic Breast Surgery increase the application rate of breast conserving surgery by obviating practical limitations and improve the results of breast conserving surgery. Correct patient and technique choice in OBS is vital for optimization of post surgical PMID:28331682

Gallstone disease is a common gastrointestinal disorder in industrialised countries. Although symptoms can be severe, some people can be symptom free for many years after the original attack. Surgery is the current treatment of choice, but evidence suggests that observation is also feasible and safe. We reviewed the evidence on cholecystectomy versus observation for uncomplicated symptomatic gallstones and conducted a cost-effectiveness analysis. We searched six electronic databases (last search April 2014). We included randomised controlled trials (RCTs) or non-randomised comparative studies where adults received either cholecystectomy or observation/conservative management for the first episode of symptomatic gallstone disease (biliary pain or cholecystitis) being considered for surgery in secondary care. Meta-analysis was used to combine results. A de novo Markov model was developed to assess the cost effectiveness of the interventions. Two RCTs (201 participants) were included. Eighty-eight percent of people randomised to surgery and 45 % of people randomised to observation underwent cholecystectomy during the 14-year follow-up period. Participants randomised to observation were significantly more likely to experience gallstone-related complications (RR = 6.69, 95 % CI = 1.57-28.51, p = 0.01), in particular acute cholecystitis (RR = 9.55, 95 % CI = 1.25-73.27, p = 0.03), and less likely to undergo surgery (RR = 0.50, 95 % CI = 0.34-0.73, p = 0.0004) or experience surgery-related complications (RR = 0.36, 95 % CI = 0.16-0.81, p = 0.01) than those randomised to surgery. Fifty-five percent of people randomised to observation did not require surgery, and 12 % of people randomised to cholecystectomy did not undergo surgery. On average, surgery costs £1,236 more per patient than conservative management, but was more effective. Cholecystectomy is the preferred treatment for symptomatic gallstones. However, approximately half the observation group did not require surgery or suffer complications indicating that it may be a valid alternative to surgery. A multicentre trial is needed to establish the effects, safety and cost effectiveness of observation/conservative management relative to cholecystectomy.

To determine whether it was feasible to perform a randomized controlled trial (RCT) comparing arthroscopic hip surgery to conservative care in patients with femoroacetabular impingement (FAI). This study had two phases: a pre-pilot and pilot RCT. In the pre-pilot, we conducted interviews with clinicians who treated FAI and with FAI patients to determine their views about an RCT. We developed protocols for operative and conservative care. In the pilot RCT, we determined the rates of patient eligibility, recruitment and retention, to investigate the feasibility of the protocol and we established methods to assess treatment fidelity. In the pre-pilot phase, 32 clinicians were interviewed, of which 26 reported theoretical equipoise, but in example scenarios 7 failed to show clinical equipoise. Eighteen patients treated for FAI were also interviewed, the majority of whom felt that surgery and conservative care were acceptable treatments. Surgery was viewed by patients as a 'definitive solution'. Patients were motivated to participate in research but were uncomfortable about randomization. Randomization was more acceptable if the alternative was available at the end of the trial. In the pilot phase, 151 patients were assessed for eligibility. Sixty were eligible and invited to take part in the pilot RCT; 42 consented to randomization. Follow-up was 100% at 12 months. Assessments of treatment fidelity were satisfactory. An RCT to compare arthroscopic hip surgery with conservative care in patients with FAI is challenging but feasible. Recruitment has started for a full RCT.

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 purpose of this retrospective outcome study was to validate the effectiveness of postoperative radiotherapy in breast conserving therapy (BCT) and to evaluate possible causes for omission of radiotherapy after breast conserving surgery (BCS) in a non-trial population. Data were provided by the population-based Munich Cancer Registry. The study included epidemiological data of 30.811 patients diagnosed with breast cancer from 1998 to 2012. The effect of omitting radiotherapy was analysed using Kaplan-Meier-estimates and Cox proportional hazard regression. Variables predicting omission of radiotherapy were analysed using multivariate logistic regression. Use of postoperative radiotherapy after BCS was associated with significant improvements in local control and survival. 10-year loco-regional recurrence-free-survival was 90.8% with postoperative radiotherapy vs. 77.6% with surgery alone (p<0.001). 10-year overall survival rates were 55.2% with surgery alone vs. 82.2% following postoperative radiotherapy (p<0.001). Variables predicting omission of postoperative radiotherapy included advanced age (women ⩾80 years; OR: 0.082; 95% CI: 0.071-0.094, p<0.001). This study shows a decrease in local control and a survival disadvantage if postoperative radiotherapy after breast conserving surgery is omitted in an unselected cohort of primary breast cancer patients. Due to its epidemiological nature, it cannot answer the question in whom postoperative radiotherapy can be safely omitted. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Conservative management for uncomplicated displaced clavicle fractures is common practice. Delay of surgical fixation may result in less favorable outcomes. A retrospective cohort study was conducted of 60 patients with a closed mid-third clavicle fracture that did not meet current operative or nonoperative guidelines; 20 primary (plate fixation <6 weeks), 20 delayed (plate fixation >6 weeks), and 20 matched conservative patients were included. Each patient completed 2 questionnaires, the Disabilities of the Arm, Shoulder, and Hand and the American Shoulder and Elbow Surgeons, as well as visual analog scales for pain, cosmetic satisfaction, and overall satisfaction. In addition, 10 patients from each group underwent clinical review of scapular rotation by the lateral scapular slide test, clinical impingement, range of motion assessment, and radiologic review of clavicle union and length. The American Shoulder and Elbow Surgeons patient self-reported questionnaire demonstrated a median score of 5.5 for the delayed group, 2 for the primary group, and 1 for the conservative group (P = .032). The median Disabilities of the Arm, Shoulder, and Hand score was 7.92 for the delayed group, 3.32 for the primary group, and 1.67 for the conservative group (P = .212). Six patients in the delayed group had scapular malrotation compared with 2 in the primary group and none in the conservative group (P = .008). Flexion and external rotation in 90° abduction were decreased in the conservative group (P = .049 and .041, respectively). We support the conservative management of uncomplicated displaced clavicle fractures but recognize that a lower threshold for early surgery should be considered where optimal shoulder function is required.

Good clinical results have been reported for both surgical and conservative treatment of rotator cuff tears. The primary aim of this randomized controlled trial was to compare functional and radiologic improvement after surgical and conservative treatment of degenerative rotator cuff tears. We conducted a randomized controlled trial that included 56 patients with a degenerative full-thickness rotator cuff tear between January 2009 and December 2012; 31 patients were treated conservatively, and rotator cuff repair was performed in 25 patients. Outcome measures, including the Constant-Murley score (CMS), visual analog scale (VAS) pain and VAS disability scores, were assessed preoperatively and after 6 weeks and 3, 6, and 12 months. Magnetic resonance imaging was performed preoperatively and at 12 months postoperatively. At 12 months postoperatively, the mean CMS was 81.9 (standard deviation [SD], 15.6) in the surgery group vs 73.7 (SD, 18.4) in the conservative group (P = .08). VAS pain (P = .04) and VAS disability (P = .02) were significantly lower in the surgery group at the 12-month follow-up. A subgroup analysis showed postoperative CMS results were significantly better in surgically treated patients without a retear compared with conservatively treated patients (88.5 [SD, 6.2] vs 73.7 [SD, 18.4]). In our population of patients with degenerative rotator cuff tears who were randomly treated by surgery or conservative protocol, we did not observe differences in functional outcome as measured with the CMS 1 year after treatment. However, significant differences in pain and disabilities were observed in favor of surgical treatment. The best outcomes in function and pain were seen in patients with an intact rotator cuff postoperatively. Copyright © 2015 Journal of Shoulder and Elbow Surgery Board of Trustees.

Background Progressive visual loss after coil embolization of a large internal carotid ophthalmic aneurysm has been widely reported. It is generally accepted that the primary strategy for this complication should be conservative, including steroid therapy; however, it is not well known as to what approach to take when the conservative therapy is not effective. Case Presentation We report a case of a 55-year-old female presenting with progressive visual loss after the coiling of a ruptured large internal carotid ophthalmic aneurysm. As the conservative therapy had not been effective, we performed neck clipping of the aneurysm with optic canal unroofing, anterior clinoidectomy, and partial removal of the embolized coils for the purpose of optic nerve decompression. After the surgery, the visual symptom was improved markedly. Conclusions It is suggested that direct surgery for the purpose of optic nerve decompression may be one of the options when conservative therapy is not effective for progressive visual disturbance after coil embolization.

Cellulitis is a previously unreported complication of conservative surgery and radiation therapy for early stage breast cancer. Patients who presented with breast cellulitis after conservative therapy are described. Eleven patients that developed cellulitis of the breast over a 38-month period of observation are the subject of this report. Clinical characteristics of patients with cellulitis and their treatment and outcome are reported. Potential patient and treatment-related correlates for the development of cellulitis are analyzed. The risk of cellulitis persists years after initial breast cancer therapy. The clinical course of the patients was variable: some patients required aggressive, long-duration antibiotic therapy, whilemore » others had rapid resolution with antibiotics. Three patients suffered from multiple episodes of cellulitis. Patients with breast cancer treated with conservative surgery and radiotherapy are at risk for breast cellulitis. Systematic characterization of cases of cellulitis may provide insight into diagnosis, prevention, and more effective therapy for this uncommon complication. 15 refs., 1 fig., 2 tabs.« less

Congenital scoliosis - presentation of three severe cases treated conservatively.

PubMed

Weiss, H-R

2008-01-01

In view of the very limited data about conservative treatment of patients with congenital scoliosis (CS) available, early surgery is suggested already in mild cases with formation failures in the first three years of life. It is common sense that patients with failures of segmentation will not benefit from conservative treatment at all and the same applies to failures of formation with curves of >50 degrees in infancy. Two patients with rib synostosis denied surgery before entering the pubertal growth spurt. These patients have been treated conservatively with braces and Scoliosis In-Patient Rehabilitation (SIR) and now are beyond the pubertal growth spurt. One patient with a formation failure and a curve of >50 degrees lumbar has been treated with the help of braces and physiotherapy from 1.6 years on and is still under treatment now at the age of 15 years. Severe decompensation was prevented in the two patients with failure of segmentation, however a severe thoracic deformity is evident with underdeveloped lung function and severe restrictive ventilation disorder. The patient with failure of formation is well developed, now without cosmetic or physical complaints although his curve progressed at the end of the growth spurt due to final mal-compliance. Failures of segmentation should be advised to have surgery before entering the pubertal growth spurt. In case they deny, conservative treatment can at least in part be beneficial. For patients with failures of formation conservative treatment should be suggested in the first place because long-term outcomes of early surgery beyond pubertal growth spurt are not yet revealed.

Opinions differ in the international literature about the efficacy of conservative approaches to scoliosis treatment. Because this divergence of opinion corresponds to a great discrepancy in the standards applied to conservative treatment methods, it is not astonishing that the results of conservative treatment as described in the literature also differ. Scoliosis normally does not have such dramatic effects that immediate surgery would be indicated.Moreover, it is clear from the published literature that it is the functional and physiological impairments of scoliosis patients--including pain, torso deformity, psychological disturbance, and pulmonary dysfunction--which require therapeutic intervention. In Germany the triad of outpatient physiotherapy, intensive inpatient rehabilitation, and bracing has proven effective in conservative scoliosis treatment.Indication, content, and results of the individual treatment procedures are described and discussed. The positive outcomes of this practice validate a policy of offering conservative scoliosis treatment as an alternative to patients, including those for whom surgery is indicated.

The aim of this study was to measure the effect of treatment of acute Achilles tendon ruptures on calf muscle strength recovery. Eighty-three patients with acute Achilles tendon rupture were randomly allocated to either minimally invasive surgery with functional after-treatment or conservative treatment by functional bracing. Calf muscle strength using isokinetic testing was evaluated at 3 months and after 6 or more months posttreatment. To exclusively investigate the effect of treatment on outcome, the authors excluded patients with major complications from the analysis. In 31 of 39 patients in the surgical treatment group and 25 of 34 patients in the conservative treatment group, isokinetic strength tests were performed. In the analysis of differences in mean peak torque, no statistically significant differences were found between surgery and conservative treatment, except for plantar flexion strength at 90 degrees per second at the second measurement, favoring conservative treatment. After 8 to 10 months follow- up, loss of plantar flexion strength was still present in the injured leg in both treatment groups. In conclusion, isokinetic muscle strength testing did not detect a statistically significant difference between minimally invasive surgical treatment with functional after-treatment and conservative treatment by functional bracing of acute Achilles tendon ruptures.

Patients with chronic pancreatitis usually have a long and debilitating history of disease with frequent hospital admissions, episodes of intractable pain and multiple interventions. The sequences of treatment at initial presentation, endoscopy, surgery, or conservative treatment may affect the time course and admissions needed for disease control, thereby determining quality of life and overall outcome. A total of 292 patients with initial endoscopic, surgical, or conservative pharmacological treatment were retrospectively analyzed regarding frequency of interventions, days in hospital, symptom-free intervals, morbidity, and mortality. Quality of life (QoL) at the latest follow-up was measured by two standardized quality of life questionnaires (EORTC C30 and PAN26). Endoscopic treatment was initially performed in 150 (51.4%) patients, whereas 99 (33.9%) underwent surgery and 43 (14.7%) patients were treated conservatively at their initial presentation. Patients who underwent surgery had a significantly shorter time in the hospital (25.3 ± 24.6, 34.4 ± 35.1, 61.1 ± 37.9; P < 0.001), fewer subsequent therapies (0.43 ± 1.0, 2.1 ± 2.4, 3.1 ± 3.0; P ≤ 0.001), and a longer relapse-free interval (P = 0.004) compared with endoscopically treated patients. The overall complication rate was 32% both after surgery and endoscopy. Infectious-related complications occurred more often after surgical treatment (P ≤ 0.001), whereas patients after endoscopic intervention developed acute or chronic pancreatitis or pseudocyst formation (P = 0.023). Patients who undergo surgery as their initial treatment for chronic pancreatitis require less consecutive interventions, a shorter hospital stay, and have a better quality of life compared with any other treatment. Surgery should therefore be considered early for the treatment of chronic pancreatitis, when endoscopic or conservative treatment fails and patients require further intervention.

Study Design Literature review. Objective Since the 1970s, spine surgeons have commonly required 6 weeks of failed conservative treatment prior to considering surgical intervention for various spinal pathologies. It is unclear, however, if this standard has been validated in the literature. The authors review the natural history, outcomes, and cost-effectiveness studies relating to the current standard of 6 weeks of nonoperative care prior to surgery for patients with spinal pathologies. Methods A systematic Medline search from 1953 to 2013 was performed to identify natural history, outcomes, and cost-effectiveness studies relating to the optimal period of conservative management prior to surgical intervention for both cervical and lumbar radiculopathy. Demographic information, operative indications, and clinical outcomes are reviewed for each study. Results A total of 5,719 studies were identified; of these, 13 studies were selected for inclusion. Natural history studies demonstrated that 88% of patients with cervical radiculopathy and 70% of patients with lumbar radiculopathy showed improvement within 4 weeks following onset of symptoms. Outcomes and cost-effectiveness studies supported surgical intervention within 8 weeks of symptom onset for both cervical and lumbar radiculopathy. Conclusions There are limited studies supporting any optimal duration of conservative treatment prior to surgery for cervical and lumbar radiculopathy. Therefore, evidence-based conclusions cannot be made. Based on the available literature, we suggest that an optimal timing for surgery following cervical radiculopathy is within 8 weeks of onset of symptoms. A shorter period of 4 weeks may be appropriate based on natural history studies. Additionally, we found that optimal timing for surgery following lumbar radiculopathy is between 4 and 8 weeks. A prospective study is needed to explicitly identify the optimal duration of conservative therapy prior to surgery so that costs may be reduced and patient outcomes improved. PMID:25396110

The breast cancer is the most common cancer in women, both in Poland and in the world. Consequences entail a disruption in the physical, psychological and social functioning. The aim of the study was to assess the acceptance of illness by patients treated for breast cancer in the early postoperative period. The research was conducted on the group of 100 consecutive patients aged 32-80 years (median 56 years) who underwent surgery for breast cancer in the Centre of Oncology in Bydgoszcz w 2014 roku. 68 of women had mastectomy, 32 of women had conservative surgery. Polling was conducted in the early period after surgery. The original questionnaire containing closed questions the scale of acceptance of the disease (AIS) as well as mental adaptation to cancer (Mini-Mac) was used in the study. 38% of patients had high acceptance of the disease, 48% average and 14% had low acceptance. Patients after conservative surgery had a higher average values for the mental strategies to cope with the disease, for the fighting spirit (23.1), helplessness and hopelessness (13.5), positive revaluation (23), the patients had a lower average (16.5) in the strategy to absorb anxiety. Patients after conservative surgery had a higher average for constructive style (2.6) but lower for destructive style (1.5). High level of mental coping with the disease was observed in 53%of patients with constructive style and 4% of patients with destructive style. While, a low level of mental coping with the dosease was observed in 5% of patients with constructive style and 46% of patients with destructive style. Almost half of women after mastectomy or conservative surgery had an average acceptance of the disease. The disease was accepted best by educated women living in the cities, white-collar workers with a good economic situation. The following factors were affected the better management of the disease, in order: age, education, current occupation and economic situation, while the type of surgery did not affect better management. More than half of women, regardless of the type of surgery reflected the high level of constructive style.

Cervical radicular syndrome (CRS) due to a herniated disc can be safely treated by surgical decompression of the spinal root. In the vast majority of cases this relieves pain in the arm and restores function. However, conservative treatment also has a high chance on relieving symptoms. The objective of the present study is to evaluate the (cost-) effectiveness of surgery versus prolonged conservative care during one year of follow-up, and to evaluate the timing of surgery. Predisposing factors in favour of one of the two treatments will be evaluated. Patients with disabling radicular arm pain, suffering for at least 2 months, and an MRI-proven herniated cervical disc will be randomised to receive either surgery or prolonged conservative care with surgery if needed. The surgical intervention will be an anterior discectomy or a posterior foraminotomy that is carried out according to usual care. Surgery will take place within 2-4 weeks after randomisation. Conservative care starts immediately after randomisation. The primary outcome measure is the VAS for pain or tingling sensations in the arm one year after randomisation. In addition, timing of surgery will be studied by correlating the primary outcome to the duration of symptoms. Secondary outcome measures encompass quality of life, costs and perceived recovery. Predefined prognostic factors will be evaluated. The total follow-up period will cover two years. A sample size of 400 patients is needed. Statistical analysis will be performed using a linear mixed model which will be based on the 'intention to treat' principle. In addition, a new CRS questionnaire for patients will be developed, the Leiden Cervical Radicular Syndrome Functioning (LCRSF) scale. The outcome will contribute to better decision making for the treatment of cervical radicular syndrome. NTR3504.

To evaluate the cumulative recurrence rates of ovarian endometrioma among patients using a levonorgestrel-releasing intrauterine system (LNG-IUS) after conservative laparoscopic surgery. A retrospective review was conducted of premenopausal women who underwent conservative laparoscopic surgery for ovarian endometrioma and subsequent treatment with LNG-IUS at two gynecologic surgery centers in South Korea between January 1, 2007, and September 30, 2014. Eligible patients had no residual ovarian lesions before LNG-IUS insertion, underwent insertion within 12 months of primary surgery, and were followed up for at least 6 months afterwards. Recurrence was defined as a cystic mass (≥2 cm in diameter) detected by transvaginal ultrasonography. Overall, 61 patients were included. The mean duration of follow-up was 42.9 ± 22.0 months (range 8-98). Recurrence of ovarian endometrioma was detected among 7 (11%) of the patients. On Kaplan-Meier analysis, the cumulative recurrence rates were 4.0%, 6.3%, and 25.5% at 24, 36, and 60 months after surgery, respectively. In multivariate analysis, nulliparity at surgery was the only risk factor for recurrence (hazard ratio 5.892, 95% confidence interval 1.139-30.484; P=0.034). Long-term maintenance therapy with LNG-IUS after conservative surgery might be a treatment option to consider to prevent ovarian endometrioma recurrence among premenopausal women.

Background Role of chemotherapy in patients who continue to have unresectable disease after pre-operative chemo-radiotherapy (CRT) remains largely unaddressed. Methods Patients with LA rectal cancer from January 2013 to June 2015 were evaluated. Post-CRT, patients, who were deemed unresectable, were considered for further interim chemotherapy (i-CT). Results Seventy six patients (15%) with median age of 38.5 years received i-CT after CRT. About 61.8% patients receiving i-CT managed to undergo a definitive surgery and the extent of surgery was reduced in 48.7% patients. With the median follow up of 19 months, the estimated 2-year event free survival (EFS) of 48% and OS was 56%. The estimated 2-year OS was 81% in mucinous tumors whereas it was 44.4% in signet ring pathology (P=0.045). The 2-year OS of 86% for whom surgery was done vs. 38% (2-year OS) in whom surgery was not done (P=0.011). Survival was better in conservative surgery group vs. total pelvic exenteration (TPE) vs. no surgery (2-year OS: 84% vs. 59.1% vs. 38%; P=0.033). In the CAPE-OX group, 71.4% (14/23) underwent surgery whereas 75.9% (29/47) in the 5-FU plus irinotecan plus oxaliplatin (FOLFIRINOX) group with EFS (P=0.570) and OS (P=0.120). In conservative surgery group, OS was better in FOLFIRINOX (2-year OS: 95.7%) vs. capecitabine plus oxaliplatin (CAPOX) (2-year OS: 70%) (P=0.012). Conclusions i-CT can lead to improved resection rates, improved survivals and downstaging with acceptable toxicity. FOLFIRINOX appears to better over CAPOX, specifically in whom conservative surgery is feasible. PMID:28078119

To update and examine national temporal trends in contralateral prophylactic mastectomy (CPM) and determine whether survival differed for invasive breast cancer patients based on hormone receptor (HR) status and age. We identified women diagnosed with unilateral stage I to III breast cancer between 1998 and 2012 within the Surveillance, Epidemiology, and End Results registry. We compared characteristics and temporal trends between patients undergoing breast-conserving surgery, unilateral mastectomy, and CPM. We then performed Cox proportional-hazards regression to examine breast cancer-specific survival (BCSS) and overall survival (OS) in women diagnosed between 1998 and 2007, who underwent breast-conserving surgery with radiation (breast-conserving therapy), unilateral mastectomy, or CPM, with subsequent subgroup analysis stratifying by age and HR status. Of 496,488 women diagnosed with unilateral invasive breast cancer, 59.6% underwent breast-conserving surgery, 33.4% underwent unilateral mastectomy, and 7.0% underwent CPM. Overall, the proportion of women undergoing CPM increased from 3.9% in 2002 to 12.7% in 2012 (P < 0.001). Reconstructive surgery was performed in 48.3% of CPM patients compared with only 16.0% of unilateral mastectomy patients, with rates of reconstruction with CPM rising from 35.3% in 2002 to 55.4% in 2012 (P < 0.001). When compared with breast-conserving therapy, we found no significant improvement in BCSS or OS for women undergoing CPM (BCSS: HR 1.08, 95% confidence interval 1.01-1.16; OS: HR 1.08, 95% confidence interval 1.03-1.14), regardless of HR status or age. The use of CPM more than tripled during the study period despite evidence suggesting no survival benefit over breast conservation. Further examination on how to optimally counsel women about surgical options is warranted.

Oncoplastic surgery in the treatment of breast cancer

2013-01-01

Advances in reconstructive breast surgery with new materials and techniques now allow us to offer our patients the best possible cosmetic results without the risks associated with oncological control of the disease. These advances, in both oncological and plastic surgery, have led to a new specialisation, namely oncoplastic breast surgery, which enables us to undertake large resections and, with advance planning, to prevent subsequent deformities. This is particularly important when more than 30% of the breast volume is removed, as it allows us to obtain precise information for conservative surgery according to the site of the lesion, and also allows us to set the boundary between conservative surgery and mastectomy. Given the existence of new alloplastic materials and new reconstructive techniques, it is essential for our patients that surgeons involved in breast cancer treatment are trained in both the oncological as well as the reconstructive and aesthetic fields, to enable them to provide the best loco-regional treatment with the best cosmetic results.

Income level and regional policies, underlying factors associated with unwarranted variations in conservative breast cancer surgery in Spain

PubMed Central

2011-01-01

Background Geographical variations in medical practice are expected to be small when the evidence about the effectiveness and safety of a particular technology is abundant. This would be the case of the prescription of conservative surgery in breast cancer patients. In these cases, when variation is larger than expected by need, socioeconomic factors have been argued as an explanation. Objectives: Using an ecologic design, our study aims at describing the variability in the use of surgical conservative versus non-conservative treatment. Additionally, it seeks to establish whether the socioeconomic status of the healthcare area influences the use of one or the other technique. Methods 81,868 mastectomies performed between 2002 and 2006 in 180 healthcare areas were studied. Standardized utilization rates of breast cancer conservative (CS) and non-conservative (NCS) procedures were estimated as well as the variation among areas, using small area statistics. Concentration curves and dominance tests were estimated to determine the impact of income and instruction levels in the healthcare area on surgery rates. Multilevel analyses were performed to determine the influence of regional policies. Results Variation in the use of CS was massive (4-fold factor between the highest and the lowest rate) and larger than in the case of NCS (2-fold), whichever the age group. Healthcare areas with higher economic and instruction levels showed highest rates of CS, regardless of the age group, while areas with lower economic and educational levels yielded higher rates of NCS interventions. Living in a particular Autonomous Community (AC), explained a substantial part of the CS residual variance (up to a 60.5% in women 50 to 70). Conclusion The place where a woman lives -income level and regional policies- explain the unexpectedly high variation found in utilization rates of conservative breast cancer surgery. PMID:21504577

Background: In conservative breast surgery, the achievement of a satisfactory cosmetic result could be challenging; oncoplastic techniques may be helpful in many cases. A comparative analysis was performed among 3 groups of patients undergoing oncoplastic techniques plus external radiation therapy or intraoperative radiotherapy (IORT) and breast conservative surgery plus external radiation therapy; long-term oncologic results in terms of disease relapse and aesthetic outcomes were compared. Methods: Ninety-six patients were considered: 32 patients treated with oncoplastic surgery, 16 then subjected to radiotherapy (group 1) and another 16 treated with IORT (group 2); 64 patients treated by conservative surgery and radiotherapy formed the control group (group 3). Patients were asked to give a judgment on the cosmetic result considering the following parameters: breast symmetry, appearance of the residual scar, symmetry between the 2 nipple-areola complexes, global aesthetic judgment, and satisfaction about the result. Results: With respect to the oncological and aesthetic outcome, the statistical significance of the results obtained in the 3 groups was calculated using the chi-square test. The results, processed by the chi-square test, were not statistically significant; however, the overall judgments expressed by the patients of all 3 groups were more than satisfactory (scores greater than or equal to 6). Conclusions: In our experience, when the inclusion criteria are satisfied and the equipment is available, oncoplastic techniques associated with IORT should be considered the treatment of choice for breast cancer in early stage. The excellent cosmetic results and patient’s satisfaction encourage us to continue on this way. PMID:26034646

Purpose: To report the outcomes of a population of women with ductal carcinoma in situ (DCIS) treated with breast-conserving surgery and radiation and to evaluate the independent effect of boost radiation on the development of local recurrence. Methods and Materials: All women diagnosed with DCIS and treated with breast-conserving surgery and radiation therapy in Ontario from 1994 to 2003 were identified. Treatments and outcomes were identified through administrative databases and validated by chart review. The impact of boost radiation on the development of local recurrence was determined using survival analyses. Results: We identified 1895 cases of DCIS that were treatedmore » by breast-conserving surgery and radiation therapy; 561 patients received boost radiation. The cumulative 10-year rate of local recurrence was 13% for women who received boost radiation and 12% for those who did not (P=.3). The 10-year local recurrence-free survival (LRFS) rate among women who did and who did not receive boost radiation was 88% and 87%, respectively (P=.27), 94% and 93% for invasive LRFS (P=.58), and was 95% and 93% for DCIS LRFS (P=.31). On multivariable analyses, boost radiation was not associated with a lower risk of local recurrence (hazard ratio = 0.82, 95% confidence interval 0.59-1.15) (P=.25). Conclusions: Among a population of women treated with breast-conserving surgery and radiation for DCIS, additional (boost) radiation was not associated with a lower risk of local or invasive recurrence.« less

Timing of surgery for sciatica: subgroup analysis alongside a randomized trial

Surgery speeds up recovery for sciatica. Prolonged conservative care with surgery for those patients with persistent sciatica however, yields similar results at 1 year. To investigate whether baseline variables modify the difference in recovery rates between these treatment strategies, baseline data of 283 patients enrolled in a randomized trial, comparing early surgery with prolonged conservative care, were used to analyse effect modification of the allotted treatment strategy. For predictors shown to modify the effect of the treatment strategy, repeated measurement analyses with the Roland Disability Questionnaire and visual analogue scale pain as continuous outcomes were performed for every level of that predictor. Presumed predictive variables did not have any interaction with treatment, while “sciatica provoked by sitting” showed to be a significant effect modifier (P = 0.07). In a Cox model we estimated a hazard ratio (HR, surgery versus conservative) of 2.2 (95% CI 1.7–3.0) in favour of surgery when sciatica was provoked by sitting, while the HR was 1.3 (95% CI 0.8–2.2) when this sign was absent. The interaction effect is marginally significant (interactions are usually tested at the 10% level) but the patterns generated by the repeated measurement analyses of all primary outcomes are completely consistent with the inferred pattern from the survival analysis. Classical signs did not show any contribution as decision support tools in deciding when to operate for sciatica, whereas treatment effects of early surgery are emphasized when sciatica is provoked by sitting and negligible when this symptom is absent.

No previous studies have reported the radiological features of patients requiring surgery in symptomatic lumbar foraminal stenosis (LFS). This study aims to investigate the diagnostic accuracy of a novel technique, foraminal stenotic ratio (FSR), using three-dimensional magnetic resonance imaging for LFS at L5-S by comparing patients requiring surgery, patients with successful conservative treatment, and asymptomatic patients. This is a retrospective radiological comparative study. We assessed the magnetic resonance imaging (MRI) results of 84 patients (168 L5-S foramina) aged ≥40 years without L4-L5 lumbar spinal stenosis. The foramina were divided into three groups following standardized treatment: stenosis requiring surgery (20 foramina), stenosis with successful conservative treatment (26 foramina), and asymptomatic stenotic foramen (122 foramina). Foraminal stenotic ratio was defined as the ratio of the length of the stenosis to the length of the foramen on the reconstructed oblique coronal image, referring to perineural fat obliterations in whole oblique sagittal images. We also evaluated the foraminal nerve angle and the minimum nerve diameter on reconstructed images, and the Lee classification on conventional T1 images. The differences in each MRI parameter between the groups were investigated. To predict which patients require surgery, receiver operating characteristic (ROC) curves were plotted after calculating the area under the ROC curve. The FSR showed a stepwise increase when comparing asymptomatic, conservative, and surgical groups (mean, 8.6%, 38.5%, 54.9%, respectively). Only FSR was significantly different between the surgical and conservative groups (p=.002), whereas all parameters were significantly different comparing the symptomatic and asymptomatic groups. The ROC curve showed that the area under the curve for FSR was 0.742, and the optimal cutoff value for FSR for predicting a surgical requirement in symptomatic patients was 50% (sensitivity, 75%; specificity, 80.7%). The FSR determined LFS requiring surgery among symptomatic patients, with moderate accuracy. Foramina occupied ≥50% by fat obliteration were likely to fail conservative treatment, with a positive predictive value of 75%. Copyright © 2017 Elsevier Inc. All rights reserved.

Postoperative lymphatic leakage following thyroid surgery represents a management problem with considerate potential morbidity, psychological, and economical impact. Conservative and surgical management strategies for high- and low-output lymph fistulas are inconsistent. Reliable criteria to predict outcome of conservative versus surgical treatment in clinically evident lymph fistula are lacking. A retrospective single-center chart review of consecutively quality-control-documented thyroid surgeries from January 1998 to December 2009 was performed to identify reported postoperative lymph fistulas. Documentation of surgical procedures, drainage, medical, and nutritional management was analyzed to identify risk factors for occurrence and criteria for management of evident lymph fistulas. There were 29 patients identified with postoperative clinical evidence of lymph fistulas following thyroid surgery; incidence was 0.5%. Indication to surgery comprised benign nodular goiter, recurrent nodular goiter, and thyroid carcinoma or local and lymphonodal carcinoma recurrences. There were 12 (41%) primary and 17 (59%) redo surgeries performed. Surgical procedures performed included thyroidectomy, completion thyroidectomy, and primary and redo central and lateral systematic microdissection of lymphatic compartments. All patients were initially submitted to fasting diet and medical treatment, successfully in 19 (66%), whereas ten (34%) patients underwent surgical intervention for fistula closure after failure of conservative treatment. Complications were one wound infection and fistula recurrence in five (26%) patients in the conservative group and two (20%) in the surgical group. Hospital stay was exceedingly prolonged in both groups with a median of 21 and 11 versus 6 days in patients with regular postoperative course following thyroid surgery. Data of this series support definition of the two categories of high- and low-output fistulas according to drainage collection with >300 versus <200 ml/day. Fasting in low-output fistula facilitates conservative treatment with closed drainage, whereas in high-output fistulas surgical intervention should be sought. Attendant criteria for treatment stratification are equally important, like patient's compliance, nutritional, and general health status as well as evidence for wound infection. Surgical closure of lymph fistula may be demanding when identification of the secreting fistula is limited and even muscle flap fortification may fail. Ultimately, in unsuccessfully reoperated fistula recurrences, open drainage may become necessary. Lymph fistulas cause significantly prolonged hospital stay, possible critical clinical decay, and unfavorable cosmetic and oncologic outcome while the superior management remains to be defined.

Indicators for surgery in adhesive bowel obstruction.

There is lack of data on risk factors, which, if present, would indicate the need for surgery in patients with adhesive bowel obstruction. A Cohort of 100 consecutive patients with adhesive obstruction was studied prospectively to compare clinical and investigative parameters between the operative and conservative group. It was found that female gender, previous obstetric or gynaecological procedures, pulse and BP on admission, nature of nasogastric aspirate, single distended loop on abdominal x-ray as also predominant ileal distension were independent factors indicating a high probability of surgical intervention. Patients with 2 or more risk factors had 12 times higher probability of surgery and in those with 3 or more the relative risk was 30 times. Patients with such risk factors should be monitored closely after admission and should be taken for surgery after an initial short trial of conservative measures.

Clinical effectiveness and cost-effectiveness of cholecystectomy compared with observation/conservative management for preventing recurrent symptoms and complications in adults presenting with uncomplicated symptomatic gallstones or cholecystitis: a systematic review and economic evaluation.

Approximately 10-15% of the adult population suffer from gallstone disease, cholelithiasis, with more women than men being affected. Cholecystectomy is the treatment of choice for people who present with biliary pain or acute cholecystitis and evidence of gallstones. However, some people do not experience a recurrence after an initial episode of biliary pain or cholecystitis. As most of the current research focuses on the surgical management of the disease, less attention has been dedicated to the consequences of conservative management. To determine the clinical effectiveness and cost-effectiveness of cholecystectomy compared with observation/conservative management in people presenting with uncomplicated symptomatic gallstones (biliary pain) or cholecystitis. We searched all major electronic databases (e.g. MEDLINE, EMBASE, Science Citation Index, Bioscience Information Service, Cochrane Central Register of Controlled Trials) from 1980 to September 2012 and we contacted experts in the field. Evidence was considered from randomised controlled trials (RCTs) and non-randomised comparative studies that enrolled people with symptomatic gallstone disease (pain attacks only and/or acute cholecystitis). Two reviewers independently extracted data and assessed the risk of bias of included studies. Standard meta-analysis techniques were used to combine results from included studies. A de novo Markov model was developed to assess the cost-effectiveness of the interventions. Two Norwegian RCTs involving 201 participants were included. Eighty-eight per cent of people randomised to surgery and 45% of people randomised to observation underwent cholecystectomy during the 14-year follow-up period. Participants randomised to observation were significantly more likely to experience gallstone-related complications [risk ratio = 6.69; 95% confidence interval (CI) 1.57 to 28.51; p = 0.01], in particular acute cholecystitis (risk ratio = 9.55; 95% CI 1.25 to 73.27; p = 0.03), and less likely to undergo surgery (risk ratio = 0.50; 95% CI 0.34 to 0.73; p = 0.0004), experience surgery-related complications (risk ratio = 0.36; 95% CI 0.16 to 0.81; p = 0.01) or, more specifically, minor surgery-related complications (risk ratio = 0.11; 95% CI 0.02 to 0.56; p = 0.008) than those randomised to surgery. Fifty-five per cent of people randomised to observation did not require an operation during the 14-year follow-up period and 12% of people randomised to cholecystectomy did not undergo the scheduled operation. The results of the economic evaluation suggest that, on average, the surgery strategy costs £1236 more per patient than the conservative management strategy but was, on average, more effective. An increase in the number of people requiring surgery while treated conservatively corresponded to a reduction in the cost-effectiveness of the conservative strategy. There was uncertainty around some of the parameters used in the economic model. The results of this assessment indicate that cholecystectomy is still the treatment of choice for many symptomatic people. However, approximately half of the people in the observation group did not require surgery or suffer complications in the long term indicating that a conservative therapeutic approach may represent a valid alternative to surgery in this group of people. Owing to the dearth of current evidence in the UK setting a large, well-designed, multicentre trial is needed. The study was registered as PROSPERO CRD42012002817.

The aim of the study was to evaluate the level of anxiety and pain in women with breast cancer. Patients who had been treated with modified radical mastectomy or breast conserving surgery were included. Data were gathered using the state-trait anxiety inventory and the visual analog scale. The pain levels and analgesic consumption of the patients were evaluated after surgery. The study sample consisted of 150 women. The mean age of the participants was 50.54±10.02. Most of the patients (58%) received breast conserving surgery. The mean state anxiety score was 44.74±11.91, and the mean trait anxiety score was 48.78±9.48 before surgery. The mean pain level on the first day following surgery was 3.26±1.91 and analgesic consumption was 2.98±1.08. There was no correlation between patient pain and anxiety levels. There was very slightly positive correlation between trait anxiety and total analgesic consumption. Assessing the levels of anxiety in breast cancer patients before surgery may contribute to the determination of postoperative pain.

Patients with a hemispheric infarct and massive space-occupying brain oedema have a poor prognosis. Despite maximal conservative treatment, the case fatality rate may be as high as 80%, and most survivors are left severely disabled. Non-randomised studies suggest that decompressive surgery reduces mortality substantially and improves functional outcome of survivors. This study is designed to compare the efficacy of decompressive surgery to improve functional outcome with that of conservative treatment in patients with space-occupying supratentorial infarction The study design is that of a multi-centre, randomised clinical trial, which will include 112 patients aged between 18 and 60 years with a large hemispheric infarct with space-occupying oedema that leads to a decrease in consciousness. Patients will be randomised to receive either decompressive surgery in combination with medical treatment or best medical treatment alone. Randomisation will be stratified for the intended mode of conservative treatment (intensive care or stroke unit care). The primary outcome measure will be functional outcome, as determined by the score on the modified Rankin Scale, at one year.

A review of information from the New Mexico Tumor Registry on women diagnosed as having primary breast cancer from 1969 through 1985 revealed temporal changes in the surgical treatment of this disease. After 1980 the percentage of women receiving breast-conserving surgery for local-stage disease increased from 6% to 25%. Most surgeons performing operations for breast cancer had not performed a breast-conserving operation before 1981 but had used this procedure at least once in the period from 1981 through 1985. Women younger than 50 years or older than 80 years were most likely to undergo this procedure. In that period, radiotherapymore » after breast-conserving surgery could not be documented for 26% of the women 65 years old or younger or for 56% of the women aged 65 years or older. Thus, there has been a marked shift in New Mexico in the surgical approach to local-stage breast cancer in the 1980s. This shift involved most surgeons treating the disease and included women of all age groups. The apparent lack of adjuvant radiotherapy in some women receiving conservative surgeries may prove to be deleterious consequence of this change in surgical management.« less

Background The design of a randomized multicenter trial is presented on the effectiveness of a prolonged conservative treatment strategy compared with surgery in patients with persisting intense sciatica (lumbosacral radicular syndrome). Methods/design Patients presenting themselves to their general practitioner with disabling sciatica lasting less than twelve weeks are referred to the neurology outpatient department of one of the participating hospitals. After confirmation of the diagnosis and surgical indication MRI scanning is performed. If a distinct disc herniation is discerned which in addition covers the clinically expected site the patient is eligible for randomization. Depending on the outcome of the randomization scheme the patient will either be submitted to prolonged conservative care or surgery. Surgery will be carried out according to the guidelines and between six and twelve weeks after onset of complaints. The experimental therapy consists of a prolonged conservative treatment under supervision of the general practitioner, which may be followed by surgical intervention in case of persisting or progressive disability. The main primary outcome measure is the disease specific disability of daily functioning. Other primary outcome measures are perceived recovery and intensity of legpain. Secondary outcome measures encompass severity of complaints, quality of life, medical consumption, absenteeism, costs and preference. The main research question will be answered at 12 months after randomization. The total follow-up period covers two years. Discussion Evidence is lacking concerning the optimal treatment of lumbar disc induced sciatica. This pragmatic randomized trial, focusses on the 'timing' of intervention, and will contribute to the decision of the general practictioner and neurologist, regarding referral of patients for surgery.

Abstract Intraparenchymal hemorrhages occur in a proportion of severe traumatic brain injury TBI patients, but the role of surgery in their treatment is unclear. This international multi-center, patient-randomized, parallel-group trial compared early surgery (hematoma evacuation within 12 h of randomization) with initial conservative treatment (subsequent evacuation allowed if deemed necessary). Patients were randomized using an independent randomization service within 48 h of TBI. Patients were eligible if they had no more than two intraparenchymal hemorrhages of 10 mL or more and did not have an extradural or subdural hematoma that required surgery. The primary outcome measure was the traditional dichotomous split of the Glasgow Outcome Scale obtained by postal questionnaires sent directly to patients at 6 months. The trial was halted early by the UK funding agency (NIHR HTA) for failure to recruit sufficient patients from the UK (trial registration: ISRCTN19321911). A total of 170 patients were randomized from 31 of 59 registered centers worldwide. Of 82 patients randomized to early surgery with complete follow-up, 30 (37%) had an unfavorable outcome. Of 85 patients randomized to initial conservative treatment with complete follow-up, 40 (47%) had an unfavorable outcome (odds ratio, 0.65; 95% confidence interval, CI 0.35, 1.21; p=0.17), with an absolute benefit of 10.5% (CI, −4.4–25.3%). There were significantly more deaths in the first 6 months in the initial conservative treatment group (33% vs. 15%; p=0.006). The 10.5% absolute benefit with early surgery was consistent with the initial power calculation. However, with the low sample size resulting from the premature termination, we cannot exclude the possibility that this could be a chance finding. A further trial is required urgently to assess whether this encouraging signal can be confirmed. PMID:25738794

Background: Mammary adenoid cystic carcinoma (ACC) is a rare breast cancer. The aim of this retrospective study was to assess prognostic factors and patterns of failure, as well as the role of radiation therapy (RT), in ACC. Methods: Between January 1980 and December 2007, 61 women with breast ACC were treated at participating centers of the Rare Cancer Network. Surgery consisted of lumpectomy in 41 patients and mastectomy in 20 patients. There were 51(84%) stage pN0 and 10 stage cN0 (16%) patients. Postoperative RT was administered to 40 patients (35 after lumpectomy, 5 after mastectomy). Results: With a median follow-upmore » of 79 months (range, 6-285), 5-year overall and disease-free survival rates were 94% (95% confidence interval [CI], 88%-100%) and 82% (95% CI, 71%-93%), respectively. The 5-year locoregional control (LRC) rate was 95% (95% CI, 89%-100%). Axillary lymph node dissection or sentinel node biopsy was performed in 84% of cases. All patients had stage pN0 disease. In univariate analysis, survival was not influenced by the type of surgery or the use of postoperative RT. The 5-year LRC rate was 100% in the mastectomy group versus 93% (95% CI, 83%-100%) in the breast-conserving surgery group, respectively (p = 0.16). For the breast-conserving surgery group, the use of RT significantly correlated with LRC (p = 0.03); the 5-year LRC rates were 95% (95% CI, 86%-100%) for the RT group versus 83% (95% CI, 54%-100%) for the group receiving no RT. No local failures occurred in patients with positive margins, all of whom received postoperative RT. Conclusion: Breast-conserving surgery is the treatment of choice for patients with ACC breast cancer. Axillary lymph node dissection or sentinel node biopsy might not be recommended. Postoperative RT should be proposed in the case of breast-conserving surgery.« less

Surgery of the vulva in vulvar cancer.

Micheletti, Leonardo; Preti, Mario

2014-10-01

The standard radical mutilating surgery for the treatment of invasive vulval carcinoma is, today, being replaced by a conservative and individualised approach. Surgical conservative modifications that are currently considered safe, regarding vulval lesion, are separate skin vulval-groin incisions, drawn according to the lesion diameter, and wide local radical excision or partial radical vulvectomy with 1-2 cm of clinically clear surgical margins. Regarding inguinofemoral lymph nodes management, surgical conservative modifications not compromising patient survival are omission of groin lymphadenectomy only when tumour stromal invasion is ≤ 1 mm, unilateral groin lymphadenectomy only in well-lateralised early lesions and total or radical inguinofemoral lymphadenectomy with preservation of femoral fascia when full groin resection is needed. Sentinel lymph node dissection is a promising technique but it should not be routinely employed outside referral centres. Pelvic nodes are better managed by radiation. Locally advanced vulval carcinoma can be managed by ultraradical surgery, exclusive radiotherapy or chemoradiation. Copyright © 2014 Elsevier Ltd. All rights reserved.

Thoracic duct fistula at the cervical level is a severe but rare complication following thyroid surgery, particularly associated to lateral dissection of the neck and to mediastinal goiter. we retrospectively analyzed chylous fistulas observed in a cohort of 13.224 patients underwent surgery for thyroid disease since 1986 to 2014, in the Unit of Endocrine Surgery, S. Maria University Hospital, Terni, Italy. We observed 20 cases of chylous fistula. Thirteen patients underwent primary surgery in our institution while the remaining 7 cases had been referred to our Department from other hospitals for an already diagnosed lymphatic leak. Surgical procedures carried out included total thyroidectomy for mediastinal goiter in 4 patients, total thyroidectomy for cancer in 2 patients, unilateral functional lymphadenectomy in 11 patients and bilateral in 3. Intraoperative repair was carried out in 4 cases. Of the remaining 16 cases, 4 of the 6 fistulas with low flow leakage healed in about 30 days of conservative treatment, 2 cases instead required surgical repair. All 10 patients with "high-flow" fistula underwent surgery. Despite surgery was performed later, postoperative course in patients with late surgical repair is similar to what observed in those patients with early surgical repair. Both groups underwent cervical drainage removal in post-operative day 4. Healing of a cervical chylous fistula can be achieved by conservative medical therapy (nutritional and pharmacological) but in case of therapeutic failure with rapid decrease of general condition, the surgical approach is necessary. In our experience, duct ligation after unsuccessful conservative treatment, is the only resolutive treatment. Copyright © 2015 IJS Publishing Group Limited. Published by Elsevier Ltd.

In patients with sciatica due to a lumbar disc herniation, it is generally recommended to reserve surgical treatment for those who suffer from intolerable pain or those who demonstrate persistent symptoms after conservative management. Controversy exists about the necessity of early surgical intervention for those patients that have an additional motor deficit. The aim of this study was to compare the recovery of motor deficit among patients receiving early surgery to those receiving prolonged conservative treatment. Subgroup analysis of a randomized controlled trial. This subgroup analysis focuses on 150 (53%) of 283 patients with sciatica due to a lumbar disc herniation and whose symptoms at baseline (before randomization) were accompanied by a motor deficit. Motor deficit was assessed through manual muscle testing and graded according to the Medical Research Council (MRC) scale. In total, 150 patients with 6 to 12 weeks of sciatica due to a lumbar disc herniation and whose symptoms were accompanied by a moderate (MRC Grade 4) or severe (MRC Grade 3) motor deficit were randomly allocated to early surgery or prolonged conservative treatment. Repeated standardized neurologic examinations were performed at baseline and at 8, 26, and 52 weeks after randomization. This study was supported by a grant from the Netherlands Organization for Health Research and Development (ZonMW) and the Hoelen Foundation The Hague. Sciatica recovered among seven (10%) of the 70 patients assigned to early surgery before surgery could be performed, and of the 80 patients assigned to conservative treatment, 32 patients (40%) were treated surgically because of intolerable pain. Baseline severity of motor deficit was graded moderate in 84% of patients and severe in 16% of patients. Motor deficit recovered significantly faster among patients allocated to early surgery (p=.01), but the difference was no longer significant at 26 (p=.21) or 52 weeks (p=.92). At 1 year, complete recovery of motor deficit was found in 81% of patients allocated to early surgery and in 80% of patients allocated to prolonged conservative treatment. Perceived overall recovery of sciatica was directly related to the presence of an accompanying motor deficit. Severe motor deficit at baseline (odds ratio, 5.4; confidence interval, 1.7-17.4) and a lumbar disc herniation encompassing ≥25% of the cross-sectional area of the spinal canal (odds ratio, 6.4; confidence interval, 1.3-31.8) were the most important risk factors for persistent deficit at 1 year. Early surgery resulted in a faster recovery of motor deficit accompanying sciatica compared with prolonged conservative treatment but the difference was no longer significant during the final follow-up examination at 1 year.

More effective methods are needed for breast reconstruction after breast-conserving surgery for breast cancer. The aim of this clinical study was to assess the perioperative and long-term outcomes of adipose-derived regenerative cell (ADRC)-enriched autologous fat grafting. Ten female patients who had undergone breast-conserving surgery and adjuvant radiotherapy for breast cancer were enrolled. An ADRC-enriched fat graft prepared from the patient's adipose tissue was implanted at the time of adipose tissue harvest. The perioperative and long-term outcomes of the grafts, which included safety, efficacy, and questionnaire-based patient satisfaction, were investigated. The mean operation time was 188 ± 30 min, and the mean duration of postoperative hospitalization was 1.2 ± 0.4 days. No serious postoperative complications were associated with the procedure. Neither recurrence nor metastatic disease was observed during the follow-up period (7.8 ± 1.5 years) after transplantation. Of 9 available patients, "more than or equal to average" satisfaction with breast appearance and overall satisfaction were reported by 6 (66.7%) and 5 (55.6%) patients, respectively. ADRC-enriched autologous fat transplantation is thus considered to be safe perioperatively, with no long-term recurrence, for patients with breast cancer treated by breast-conserving surgery, and it may be an option for breast reconstruction, even after adjuvant radiotherapy.

Purpose: To evaluate the local control rates and patterns of metastatic relapse in patients with localized myxoid liposarcoma treated with conservation surgery and radiotherapy (RT). Patients and Methods: Between 1960 and 2003, 127 patients with non-metastatic myxoid liposarcoma were treated with conservation surgery and RT at our institution. The median patient age was 39 years (range, 14-79 years). Of the 127 patients, 46% underwent preoperative RT (median dose, 50 Gy) and 54% underwent postoperative RT (median dose, 60 Gy). Also, 28% received doxorubicin-based chemotherapy as a part of their treatment. Results: The median follow-up was 9.1 years. The overall survivalmore » rate at 5 and 10 years was 87% and 79%, respectively. The corresponding disease-free survival rates were 81% and 73%. The local control rate at {>=}5 years was 97%. The actuarial rate of distant metastases at 5 and 10 years was 15% and 24%, respectively. Of the 27 patients who developed distant metastases, 48% did so in the retroperitoneum, 22% in other extrapulmonary soft tissues, 22% in the lung, 15% in bone, and 4% in the liver. Conclusion: The results of our study have shown that RT and conservation surgery for localized myxoid liposarcoma provide excellent local control. Distant metastatic relapse tended to occur in the retroperitoneum and other nonpulmonary soft tissues. Therefore, staging and surveillance imaging should include the abdomen and pelvis, as well as the thorax, for patients with localized myxoid liposarcoma.« less

Recent introduction of breast units, mass-screening programmes (SP) and sentinel node biopsy (SNB) has impacted on the clinical care of breast cancer patients (BC), resulting in a significant increase of breast-conserving surgery with the goal of achieving completely free margins and good cosmetic outcome, along with significantly less axillary morbidity. In order to ascertain the combined impact of SP and SNB on BC patients, we have reviewed the primary therapeutic approach of patients diagnosed with invasive breast carcinoma in our centre, both before and after implementation of the two new procedures. 1,942 patients operated for BC between 1997 and 2013 in two clinical centres. Two historical periods were considered: before and after the advent of the Breast Unit in our institutions and the concurrent implementation of SP and SNB (September 2002). Rates of breast-conserving surgery and re-operations improved in the second period. Intraoperative margin re-excision increased in the second period. Breast-conserving surgery decreased in parallel to stage: from 79 % for stage I to 31 % for stage III. The Cox analysis, including stage as adjusted for all significant variables, showed statistically significant differences in favour of the initial stages but only for specific mortality, not overall mortality. Combined implementation of breast units, SP, and SNB have resulted in a significant improvement of BC treatment leading to increased rates of breast-conserving surgery and decreased disease recurrence and mortality.

Femoroacetabular impingement (FAI) syndrome is a recognised cause of young adult hip pain. There has been a large increase in the number of patients undergoing arthroscopic surgery for FAI; however, a recent Cochrane review highlighted that there are no randomised controlled trials (RCTs) evaluating treatment effectiveness. We aim to compare the clinical and cost-effectiveness of arthroscopic surgery versus best conservative care for patients with FAI syndrome. We will conduct a multicentre, pragmatic, assessor-blinded, two parallel arm, RCT comparing arthroscopic surgery to physiotherapy-led best conservative care. 24 hospitals treating NHS patients will recruit 344 patients over a 26-month recruitment period. Symptomatic adults with radiographic signs of FAI morphology who are considered suitable for arthroscopic surgery by their surgeon will be eligible. Patients will be excluded if they have radiographic evidence of osteoarthritis, previous significant hip pathology or previous shape changing surgery. Participants will be allocated in a ratio of 1:1 to receive arthroscopic surgery or conservative care. Recruitment will be monitored and supported by qualitative intervention to optimise informed consent and recruitment. The primary outcome will be pain and function assessed by the international hip outcome tool 33 (iHOT-33) measured 1-year following randomisation. Secondary outcomes include general health (short form 12), quality of life (EQ5D-5L) and patient satisfaction. The primary analysis will compare change in pain and function (iHOT-33) at 12 months between the treatment groups, on an intention-to-treat basis, presented as the mean difference between the trial groups with 95% CIs. The study is funded by the Health Technology Assessment Programme (13/103/02). Ethical approval is granted by the Edgbaston Research Ethics committee (14/WM/0124). The results will be disseminated through open access peer-reviewed publications, including Health Technology Assessment, and presented at relevant conferences. ISRCTN64081839; Pre-results.

Time Interval From Breast-Conserving Surgery to Breast Irradiation in Early Stage Node-Negative Breast Cancer: 17-Year Follow-Up Results and Patterns of Recurrence

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

Vujovic, Olga, E-mail: olga.vujovic@lhsc.on.ca; Yu, Edward; Cherian, Anil

Purpose: A retrospectivechart review was conducted to determine whether the time interval from breast-conserving surgery to breast irradiation (surgery-radiation therapy interval) in early stage node-negative breast cancer had any detrimental effects on recurrence rates. Methods and Materials: There were 566 patients with T1 to T3, N0 breast cancer treated with breast-conserving surgery and breast irradiation and without adjuvant systemic treatment between 1985 and 1992. The surgery-to-radiation therapy intervals used for analysis were 0 to 8 weeks (201 patients), >8 to 12 weeks (233 patients), >12 to 16 weeks (91 patients), and >16 weeks (41 patients). Kaplan-Meier estimates of time to local recurrence, disease-free survival, distantmore » disease-free survival, cause-specific survival, and overall survival rates were calculated. Results: Median follow-up was 17.4 years. Patients in all 4 time intervals were similar in terms of characteristics and pathologic features. There were no statistically significant differences among the 4 time groups in local recurrence (P=.67) or disease-free survival (P=.82). The local recurrence rates at 5, 10, and 15 years were 4.9%, 11.5%, and 15.0%, respectively. The distant disease relapse rates at 5, 10, and 15 years were 10.6%, 15.4%, and 18.5%, respectively. The disease-free failure rates at 5, 10, and 15 years were 20%, 32.3%, and 39.8%, respectively. Cause-specific survival rates at 5, 10, and 15 years were 92%, 84.6%, and 79.8%, respectively. The overall survival rates at 5, 10, and 15 years were 89.3%, 79.2%, and 66.9%, respectively. Conclusions: Surgery-radiation therapy intervals up to 16 weeks from breast-conserving surgery are not associated with any increased risk of recurrence in early stage node-negative breast cancer. There is a steady local recurrence rate of 1% per year with adjuvant radiation alone.« less

Breast cancer is the leading oncological cause of death in Mexican women over 25 years old. Given the need to improve postoperative cosmetic results in patients with breast cancer, oncoplastic surgery has been developed, which allows larger tumour resections and minor cosmetic alterations. To determine the oncological feasibility and cosmetic outcome of oncoplastic surgery at the Instituto de Enfermedades de la Mama, FUCAM, AC. A review was conducted from January 2010 to July 2013, which included patients with breast cancer diagnosis treated with conventional breast-conserving surgery or with oncoplastic surgery in the Institute of Diseases of the Breast, FUCAM AC. Clinical and histopathological parameters were compared between the two groups, and a questionnaire of cosmetic satisfaction and quality of life was applied. Of the 171 patients included, 95 of them were treated with conventional breast-conserving surgery and 76 with oncoplastic surgery. Pathological tumour size was significantly larger in patients treated with oncoplastic surgery (p = 0.002). There were no differences found between the groups as regards the number of patients with positive surgical margin, the rate of complications, and cosmetic satisfaction. This study demonstrates the oncological feasibility and high cosmetic satisfaction of oncoplastic surgery with minimal psycho-social impact on patients.

Hallux valgus (HV) is a common foot deformity. In severe stages of this condition, surgery is often necessary. Currently, there is no systematic review comparing the effectiveness of surgery over conservative treatment. The objective of this review was to establish the effectiveness of surgery compared to conservatory management for adults with HV. The current review included adults (18 years or over) with HV deformity, excluding adults with neurological problems causing foot deformities, for example, cerebral palsy, neuropathy, stroke and multiple sclerosis. The review included any type of HV surgery compared to no surgery, conservative treatment or different types of HV surgeries. The primary outcome was gait measurement, and secondary outcomes included quality of life, patient satisfaction, pain assessed using any validated assessment tool and adverse events. The review included randomized controlled trials. The search strategy aimed to find both published and unpublished studies. A three-step search strategy was utilized in 16 databases without language and date limitations. Papers selected for retrieval were assessed by two independent reviewers for methodological validity prior to inclusion in the review using standardized critical appraisal instruments developed by the Joanna Briggs Institute (JBI). Data were extracted from papers included in the review using the standardized data extraction tool developed by the JBI. Quantitative data were, where possible, pooled in statistical meta-analysis using RevMan5 (Copenhagen: The Nordic Cochrane Centre, Cochrane). Effect sizes expressed as risk ratio (for categorical data) and mean differences (MD) or standardized MD (for continuous data) and their 95% confidence intervals were calculated for analysis. Where statistical pooling was not possible, the findings have been presented in narrative form. Searching identified 2412 citations. After removal of duplicates, paper retrieval and critical appraisal, 25 studies were included in the review. The included trials were of medium-to-poor quality.Twenty-four trials compared the effectiveness of different types of surgeries. Meta-analysis revealed no difference in level of pain between distal chevron-type osteotomy and other surgical procedures (standard mean difference [SMD] 0.02, 95% confidence interval [CI] -0.24 to 0.28). One single trial reported that distal chevron osteotomy is more effective than Lindgren osteotomy in terms of walking speed (MD -0.24, 95% CI -0.43 to -0.05).One medium quality trial assessed the effectiveness of HV surgery compared to conservative or no treatment. This trial showed that surgery, specifically distal chevron osteotomy of the first metatarsal, is a more effective procedure for pain compared to conservative treatment (MD -15.00, 95% CI -22.79 to -7.21) and also no treatment in the first year (MD -18.00, 95% CI -25.62 to -10.38). The current systematic review showed that differences between various types of surgical procedures, specifically osteotomies of the first metatarsal on clinical outcomes, are minimal. There is evidence from one study, that surgery, specifically distal chevron osteotomy of the first metatarsal is a more effective procedure than conservative or no treatment in reducing pain in the first year following surgery. However, this systematic review has identified that there is a lack of high-quality studies comparing similar types of HV treatments that assess the same outcomes.

Surgical and conservative treatment of patients with congenital scoliosis: α search for long-term results

PubMed Central

2011-01-01

Background In view of the limited data available on the conservative treatment of patients with congenital scoliosis (CS), early surgery is suggested in mild cases with formation failures. Patients with segmentation failures will not benefit from conservative treatment. The purpose of this review is to identify the mid- or long-term results of spinal fusion surgery in patients with congenital scoliosis. Methods Retrospective and prospective studies were included, reporting on the outcome of surgery in patients with congenital scoliosis. Studies concerning a small numbers of cases treated conservatively were included too. We analyzed mid-term (5 to 7 years) and long-term results (7 years or more), both as regards the maintenance of the correction of scoliosis and the safety of instrumentation, the early and late complications of surgery and their effect on quality of life. Results A small number of studies of surgically treated patients were found, contained follow-up periods of 4-6 years that in the most cases, skeletal maturity was not yet reached, and few with follow-up of 36-44 years. The results of bracing in children with congenital scoliosis, mainly in cases with failure of formation, were also studied. Discussion Spinal surgery in patients with congenital scoliosis is regarded in short as a safe procedure and should be performed. On the other hand, early and late complications are also described, concerning not only intraoperative and immediate postoperative problems, but also the safety and efficacy of the spinal instrumentation and the possibility of developing neurological disorders and the long-term effect these may have on both lung function and the quality of life of children. Conclusions Few cases indicate the long-term results of surgical techniques, in the natural progression of scoliosis. Similarly, few cases have been reported on the influence of conservative treatment. In conclusion, patients with segmentation failures should be treated surgically early, according to the rate of deformity formation and certainly before the pubertal growth spurt to try to avoid cor- pulmonale, even though there is lack of evidence for that in the long-term. Furthermore, in patients with formation failures, further investigation is needed to document where a conservative approach would be necessary. PMID:21639924

Treatment of idiopathic inflammatory bowel disease is constantly developing. Biological therapy has become a standard part of conservative treatment, and gene and cell therapy of these diseases is in preclinical phase. Surgical therapy also offers some progress in the treatment, such as the increasingly preferred laparoscopic approach offering the numerous benefits of minimally invasive surgery or a tendency to perform stapled anastomosis. A retrospective analysis of patients with a diagnosis of idiopathic inflammatory bowel operated on at the First Department of Surgery, General University Hospital in the years 2007-2011 was performed. Within this period, 179 patients diagnosed with Crohns disease were operated on. 30 patients underwent acute operation and 149 patients were indicated for elective surgery. In the same period, 40 patients with ulcerative colitis were indicated for surgery, of whom 22 patients for acute surgery and 18 for elective surgery. Multidisciplinary approach in the treatment of patients with inflammatory bowel disease is crucial and patients should be treated in specialized centres. New possibilities of conservative treatment and progress in surgical therapy mutually correlate, and thus the choice of a correct therapeutic procedure requires specific cooperation between the surgeon and the gastroenterologist.

Objective: To evaluate the prognostic value of sequencing of adjuvant radiotherapy and chemotherapy following breast-conserving surgery for patients with breast cancer. Methods: A total of 1 154 patients withT1-2N0-3M0 breast cancer retrospectively reviewed. All patients received sequential radiotherapy and chemotherapy following breast-conserving surgery. Among them, 603 patients received radiotherapy first and 551 patients received chemotherapy first. Log-rank tests were used to determine significance of disease-free survival (DFS) and overall survival (OS) rates in the Kaplan-Meier curve. Results: The 5-year DFS and OS rates for all patients were 93.0% and 97.8%. The 5-year OS rate was 98.6% in the radiotherapy first group and 96.4% in the chemotherapy first group ( P =0.191), and the corresponding DFS rate was 92.7% and 93.2% ( P =0.430), respectively. Among the patients with Luminal A subtype, the 5-year OS rate was 99.6% in the radiotherapy first group and 97.8% in the chemotherapy first group ( P =0.789). Among the patients with Luminal B subtype, the 5-year OS rate was 94.2% and 96.0%, respectively ( P =0.680). Among the patients with triple negative breast cancer, the 5-year OS rate was 100% and 90.9%, respectively, with statistically significant differences ( P =0.019). Among the patients with HER-2 positive breast cancer, The 5-year DFS rate was 80.1% and 100%, respectively ( P =0.045). Conclusions: The OS and DFS rates in the chemotherapy first group are not significantly different from those of radiotherapy first group after breast-conserving surgery. Patients with HER-2 positive breast cancer in chemotherapy first group have a much higher DFS rate than that of radiotherapy first group, whereas patients with triple negative breast cancer in radiotherapy first group have a better OS rate than that of chemotherapy first group. Further research is warranted to investigate the benefit of different molecular types in different sequencing of radiotherapy and chemotherapy after breast-conserving surgery.

Vesicoureteral reflux (VUR) is one of the most common ailments in children. Evidence-based guidelines recommend conservative treatment in children with VUR, followed by endoscopic surgery in those with breakthrough febrile urinary tract infections (UTIs). Despite this fact, the management of VUR is still controversial. Our objective is to evaluate the conservative strategy in children with primary VUR in terms of renal function and scarring, and identify factors associated with poor prognosis in those children. A retrospective study was carried out in a tertiary center in children with primary VUR under conservative strategy treatment from 1989 to 2015. Data extracted included age of presentation, family and prenatal backgrounds, radiographic evaluation including ultrasound (US), dimercaptosuccinic acid (DMSA) scans and voiding cystourethrogram (VCUG). The SPSS program was used for statistical analysis. Two-hundred and five patients were diagnosed and followed a conservative therapy scheme (49.8% males, 50.2% females) after febrile UTI (73.17%) or prenatal diagnosis (26.83%). VCUG showed 53.20% of low-moderate VUR grade, 46.80% high VUR grade. Renal damage was present at diagnosis in 40.89%. Mean follow-up reakthrough recurrent febrile UTIs and underwent surgery. Conservative therapy was followed in 189 patients. Renal scarring or decreased kidney function were shown in 15.12% respectively. Renal damage was identified as a risk factor for poor prognosis (p-value <0.005) only for renal function deterioration. Patients with high-grade VUR required surgery in a significantly greater proportion (p <0.005) due to recurrent febrile UTIs. Conservative strategy is a feasible treatment for primary VUR in children. The majority of cases could be managed conservatively with good outcomes after long-term follow-up. Decreased renal function is more frequent in patients with high-grade VUR. Renal damage at diagnosis increases the risk for surgical treatment.

Introduction The treatment of adhesive small bowel obstruction is controversial, with both operative and non-operative management practiced in different centers worldwide. Non-operative management is increasingly getting popular, though operative rates still remain high. A study to compare the efficacy of an oral water-soluble medium (Gastrografin®) with standard conservative management, both non-operative methods, in the management of this condition was conducted in a tertiary Sub Saharan hospital. Methods An open randomised controlled clinical trial was conducted between September 2012 and March 2013 at Mulago National Referral and Teaching Hospital, Uganda. Fifty patients of both genders, with adhesive small bowel obstruction, in the hospital’s emergency and general surgical wards were included. Randomisation was to Gastrografin® and standard conservative treatment groups. The primary outcomes were: the time interval between admission and relief of obstruction, the length of hospital stay, and the rates of operative surgery. Results All 50 recruited patients were followed up and analysed; 25 for each group. In the Gastrografin® group, 22 (88%) patients had relief of obstruction following the intervention, with 3 (12%) requiring surgery. The conservative treatment group had 16 (64%) patients relieved of obstruction conservatively, and 9 (36%) required surgery. The difference in operative rates between the two groups was not statistically significance (P = 0.67). Average time to relief of obstruction was shorter in the Gastrografin® group (72.52 hrs) compared to the conservative treatment group (117.75 hrs), a significant difference (P = 0.023). The average length of hospital stay was shorter in the Gastrografin® group (5.62 days) compared to the conservative treatment group (10.88 days), a significant difference (P = 0.04). Conclusion The use of Gastrografin® in patients with adhesive small bowel obstruction helps in earlier resolution of obstruction and reduces the length of hospital stay compared with standard conservative management. Its role in reducing the rate of laparotomies remains inconclusive. PMID:24729947

Recurrence of endometriosis after conservative surgery has been observed in 40-50 % of patients within the first 5 years. A variety of regimens such as combined oral contraceptives, GnRH agonists, danazol, and progestins have been used postoperatively to reduce recurrence rates. Oral contraceptives (oCP) have been used either in a cyclic or in a continuous (no pill-free interval) fashion. The purpose of this article was to summarize the existing evidence on the efficacy and patient compliance for the use of oCP in a continuous versus cyclic fashion following conservative surgery for endometriosis. A systematic search of Medline identified four eligible studies. Studies were considered eligible, if they have evaluated oCP therapy, either in a cyclic or continuous regimen, after conservative surgery for endometriosis. Specifically, studies (1) reporting on women with endometriosis who were treated postoperatively with both continuous oCP and cyclic oCP, (2) written in English, (3) with minimum 6 months duration of medical treatment, and (4) with minimum 12 months duration of follow-up were considered eligible for our systematic review. Outcome measures of these eligible studies were tabulated and then analyzed cumulatively. A purely descriptive approach was adopted concerning all variables. Postoperative use of continuous oCP was associated with a reduction in the recurrence rate of dysmenorrhea, delay in the presentation of dysmenorrhea, reduction in nonspecific pelvic pain, and reduction in the recurrence rate for endometrioma. Use of oCP in a continuous fashion following conservative surgery for endometriosis is more beneficial to cyclic use.

To review the causes and management of penile fracture and to compare between surgical and conservative management as well as immediate and delayed interventions in terms of overall and specific complications. A search of all reported literature was conducted for all articles reporting on the management and outcomes of penile fractures. Full texts of relevant articles were obtained and screened according to the inclusion criteria. Outcomes measures were numbers of patients receiving surgical or conservative management, aetiology of fracture, length of admission, complications as well as the specifics of diagnostic approaches and operative management. Data was collated and where possible meta-analysed using Revman software. A total of 58 relevant studies involving 3,213 patients demonstrated that intercourse accounts for only 48% of cases with masturbation and forced flexion accounting for 39%. Meta-analysis shows that surgical intervention was associated with significantly fewer complications vs. conservative management (p < 0.000001). Surgical intervention results in significantly less erectile dysfunction (ED), curvature and painful erection than conservative management. There was no significant difference in the number of patients developing plaques/nodules (p = 0.94). Meta-analysis shows that overall early surgery is preferable to delayed surgery but that rates of ED are not significantly different. Early surgical intervention is associated with significantly fewer complications than conservative management or delayed surgery. The combined outcome of rapid diagnosis by history and clinical examination and swift surgical intervention is key for reconstruction with minimal long-term complications. © 2016 S.

Introduction of the endoscopic techniques into gynecology enabled a change in the procedures in the case of ectopic pregnancy. This paper aims at presenting 76 cases of non-ruptured tubal pregnancies treated conservatively by the laparoscopic surgery with the application of the electrocoagulation or the Nd:YAG laser. The investigated group consisted of 76 patients. Forty-one (54%) of them were operated on using electrocoagulation and 35 (46%) using the Nd:YAG laser. Sixty-three pregnancies (83%) were localized in the ampulla. The ectopic pregnancy was confirmed histopathologically in 74 cases (97%). There were no complications noticed in the postoperative course. There were no differences in the efficacy and the postoperative general condition in cases treated conservatively by the laparoscopic surgery with the application of the electrocoagulation or the laser.

We present the first reported case of an aortic valve replacement operation without blood transfusion in a 62-year-old Jehovah's Witness with dialysis-dependent chronic renal failure, severe anemia, severe aortic stenosis, and symptomatic angina with minimal exertion after an accident in which she suffered fractures of both her right arm and leg. She underwent successful valve replacement surgery after preoperative stabilization of her fractures and high-dose erythropoietin and iron supplement therapy preoperatively and postoperatively. The intraoperative blood conservation technique included a novel approach with a miniature cardiopulmonary bypass circuit and microplegia with limited hemodilution. High-risk valve surgery in patients who are Jehovah's Witnesses can be successful with a carefully planned multimodality blood conservation strategy. PMID:17256040

Continuous positive airway pressure (CPAP) is the primary treatment of obstructive sleep apnea/hypopnea syndrome (OSA). Most sleep physicians are in agreement that a certain number of OSA patients cannot or will not use CPAP. Although other conservative therapies, such as oral appliance, sleep hygiene, and sleep positioning, may help some of these patients, there are many who fail all conservative treatments. As sleep surgeons, we have the responsibility to screen patients for both symptoms and signs of OSA. As experts of upper airway diseases, we often view an airway clearly and help the patient understand the importance of assessment and treatment for OSA. Surgery for OSA is not a substitute for CPAP but is a salvage treatment for those who failed CPAP and other conservative therapies and therefore have no other options. Most early studies and reviews focused on the efficacy of uvulopalatopharyngoplasty, a single-level procedure for the treatment of OSA. Since OSA is usually caused by multilevel obstructions, the true focus on efficacy should be on multilevel surgical intervention. The purpose here is to provide an updated overview of multilevel surgery for OSA patients. © 2017 S. Karger AG, Basel.

Effect of physician ownership of specialty hospitals and ambulatory surgery centers on frequency of use of outpatient orthopedic surgery.

Mitchell, Jean M

Physician-owned specialty hospitals and ambulatory surgery centers have become commonplace in many markets throughout the United States. Little is known about whether the financial incentives linked to ownership affect frequency of outpatient surgery. To evaluate if financial incentives linked to physician ownership influence frequency of outpatient orthopedic surgical procedures. We analyzed 5 years of claims data from a large private insurer in Idaho to compare frequency by orthopedic surgeon owners and nonowners of surgical procedures that could be performed in either ambulatory surgery centers or hospital outpatient surgery departments. Frequency of use, calculated as number of patients treated with the specific diagnoses who received the surgical procedure of interest divided by the number of patients with such diagnoses treated by each physician. Age- and sex-adjusted odds ratios indicate that the likelihood of having carpal tunnel repair was 54% to 129% higher for patients of surgeon owners compared with surgeon nonowners. For rotator cuff repair, the adjusted odds ratios of having surgery were 33% to 100% higher for patients treated by physician owners. The age- and sex-adjusted probability of arthroscopic surgery was 27% to 78% higher for patients of surgeon owners compared with surgeon nonowners. The consistent finding of higher use rates by physician owners across time clearly suggests that financial incentives linked to ownership of either specialty hospitals or ambulatory surgery centers influence physicians' practice patterns.

Does addition of low-level laser therapy (LLLT) in conservative care of knee arthritis successfully postpone the need for joint replacement?

Ip, David

2015-12-01

The current study evaluates whether the addition of low-level laser therapy into standard conventional physical therapy in elderly with bilateral symptomatic tri-compartmental knee arthritis can successfully postpone the need for joint replacement surgery. A prospective randomized cohort study of 100 consecutive unselected elderly patients with bilateral symptomatic knee arthritis with each knee randomized to receive either treatment protocol A consisting of conventional physical therapy or protocol B which is the same as protocol A with added low-level laser therapy. The mean follow-up was 6 years. Treatment failure was defined as breakthrough pain which necessitated joint replacement surgery. After a follow-up of 6 years, patients clearly benefited from treatment with protocol B as only one knee needed joint replacement surgery, while nine patients treated with protocol A needed surgery (p < 0.05). We conclude low-level laser therapy should be incorporated into standard conservative treatment protocol for symptomatic knee arthritis.

BACKGROUND Approximately 10-15% of the adult population suffer from gallstone disease, cholelithiasis, with more women than men being affected. Cholecystectomy is the treatment of choice for people who present with biliary pain or acute cholecystitis and evidence of gallstones. However, some people do not experience a recurrence after an initial episode of biliary pain or cholecystitis. As most of the current research focuses on the surgical management of the disease, less attention has been dedicated to the consequences of conservative management. OBJECTIVES To determine the clinical effectiveness and cost-effectiveness of cholecystectomy compared with observation/conservative management in people presenting with uncomplicated symptomatic gallstones (biliary pain) or cholecystitis. DATA SOURCES We searched all major electronic databases (e.g. MEDLINE, EMBASE, Science Citation Index, Bioscience Information Service, Cochrane Central Register of Controlled Trials) from 1980 to September 2012 and we contacted experts in the field. REVIEW METHODS Evidence was considered from randomised controlled trials (RCTs) and non-randomised comparative studies that enrolled people with symptomatic gallstone disease (pain attacks only and/or acute cholecystitis). Two reviewers independently extracted data and assessed the risk of bias of included studies. Standard meta-analysis techniques were used to combine results from included studies. A de novo Markov model was developed to assess the cost-effectiveness of the interventions. RESULTS Two Norwegian RCTs involving 201 participants were included. Eighty-eight per cent of people randomised to surgery and 45% of people randomised to observation underwent cholecystectomy during the 14-year follow-up period. Participants randomised to observation were significantly more likely to experience gallstone-related complications [risk ratio = 6.69; 95% confidence interval (CI) 1.57 to 28.51; p = 0.01], in particular acute cholecystitis (risk ratio = 9.55; 95% CI 1.25 to 73.27; p = 0.03), and less likely to undergo surgery (risk ratio = 0.50; 95% CI 0.34 to 0.73; p = 0.0004), experience surgery-related complications (risk ratio = 0.36; 95% CI 0.16 to 0.81; p = 0.01) or, more specifically, minor surgery-related complications (risk ratio = 0.11; 95% CI 0.02 to 0.56; p = 0.008) than those randomised to surgery. Fifty-five per cent of people randomised to observation did not require an operation during the 14-year follow-up period and 12% of people randomised to cholecystectomy did not undergo the scheduled operation. The results of the economic evaluation suggest that, on average, the surgery strategy costs £1236 more per patient than the conservative management strategy but was, on average, more effective. An increase in the number of people requiring surgery while treated conservatively corresponded to a reduction in the cost-effectiveness of the conservative strategy. There was uncertainty around some of the parameters used in the economic model. CONCLUSIONS The results of this assessment indicate that cholecystectomy is still the treatment of choice for many symptomatic people. However, approximately half of the people in the observation group did not require surgery or suffer complications in the long term indicating that a conservative therapeutic approach may represent a valid alternative to surgery in this group of people. Owing to the dearth of current evidence in the UK setting a large, well-designed, multicentre trial is needed. STUDY REGISTRATION The study was registered as PROSPERO CRD42012002817.

In spite of the fact that ductal carcinoma in situ (DCIS) of the breast is a frequently encountered clinical problem, there is no consensus about the optimal treatment of clinically occult (i.e., mammographic presentation only) DCIS. Interest in breast conservation therapy has recently increased. Few data are available in Italy on the conservative treatment with surgery and adjuvant postoperative radiotherapy. A retrospective multi-institutional study was performed in 15 Radiation Oncology Departments in northern Italy involving 112 women with subclinical DCIS of the breast treated between 1982 and 1993. Age of the patients ranged between 32 and 72 years (median, 50 years). All of them underwent conservative surgery: quadrantectomy in 89, tumorectomy in 11, and wide excision in 12 cases. The most common histologic subtype was comedocarcinoma (37%). The median pathologic size was 10 mm (range 1 to 55 mm). Axillary dissection was performed in 83 cases: all the patients were node negative. All the patients received adjunctive radiation therapy with 60Co units (77%) or 6 MV linear accelerators (23%) for a median total dose to the entire breast of 50 Gy (mean, 49.48 Gy; range, 45-60 Gy). Seventy-six cases (68%) received a boost to the tumor bed at a dose of 8-20 Gy (median 10 Gy) for a minimum tumor dose of 58 Gy. At a median follow-up of 66 months, 8 local recurrences were observed, 4 intraductal and 4 invasive. All recurrent patients had a salvage mastectomy and are alive and free of disease at this writing. The 10-year actuarial overall, cause-specific, and recurrence-free survival was of 98.8%, 100%, and 91%, respectively. The retrospective multicentric study, with a local control rate of more than 90% at 10 years with 100% cause-specific survival, showed that conservative surgery and adjuvant radiation therapy is a safe and efficacious treatment for patients with occult, non-palpable DCIS.

Conservation of transcription factor binding events predicts gene expression across species

PubMed Central

Hemberg, Martin; Kreiman, Gabriel

2011-01-01

Recent technological advances have made it possible to determine the genome-wide binding sites of transcription factors (TFs). Comparisons across species have suggested a relatively low degree of evolutionary conservation of experimentally defined TF binding events (TFBEs). Using binding data for six different TFs in hepatocytes and embryonic stem cells from human and mouse, we demonstrate that evolutionary conservation of TFBEs within orthologous proximal promoters is closely linked to function, defined as expression of the target genes. We show that (i) there is a significantly higher degree of conservation of TFBEs when the target gene is expressed in both species; (ii) there is increased conservation of binding events for groups of TFs compared to individual TFs; and (iii) conserved TFBEs have a greater impact on the expression of their target genes than non-conserved ones. These results link conservation of structural elements (TFBEs) to conservation of function (gene expression) and suggest a higher degree of functional conservation than implied by previous studies.

Surgery of Crohns disease is an important part of the general treatment algorithm. The role of surgery is changing with the development of conservative procedures. The recent years have seen the return to early treatment of patients with Crohns disease. Given the character of the disease and its intestinal symptoms, a specific approach to these patients is necessary, especially regarding the correct choice of surgery. The paper focuses on the luminal damage of the small and large intestine including complications of the disease. We describe the individual indications for a surgical solution, including the choice of anastomosis or multiple / repeated surgeries.

Background The selection of the most appropriate treatment combinations requires the balancing of benefits and harms of these treatment options as well as the patients’ preferences for the resulting outcomes. Objective This research aimed at estimating and comparing the utility weights between elderly women with early stage hormone receptor positive (HR+) breast cancer receiving a combination of radiotherapy and hormonal therapy after breast conserving surgery (BCS) and those receiving a combination of BCS and hormonal therapy. Methods The Surveillance, Epidemiology, and End Results (SEER) linked with Medicare Health Outcomes Survey (MHOS) was used as the data source. Health utility weights were derived from the VR-12 health-related quality of life instrument using a mapping algorithm. Descriptive statistics of the sample were provided. Two sample t-tests were performed to determine potential differences in mean health utility weights between the two groups after propensity score matching. Results The average age at diagnosis was 72 vs. 76 years for the treated and the untreated groups, respectively. The results showed an inverse relationship between the receipt of radiotherapy and age. Patients who received radiotherapy had, on average, a higher health utility weight (0.70; SD = 0.123) compared with those who did not receive radiotherapy (0.676; SD = 0.130). Only treated patients who had more than two comorbid conditions had significantly higher health utility weights compared with patients who were not treated. Conclusions The mean health utility weights estimated for the radiotherapy and no radiotherapy groups can be used to inform a comparative cost-effectiveness analysis of the treatment options. However, the results of this study may not be generalizable to those who are outside a managed care plan because MHOS data is collected on managed care beneficiaries. PMID:27819160

Lipofilling is now performed to improve the breast contour, after both breast-conserving surgery and breast reconstruction. However, injection of fat into a previous tumor site may create a new environment for cancer and adjacent cells. There is also no international agreement regarding lipofilling after breast cancer treatment. The authors included three institutions specializing in both breast cancer treatment and breast reconstruction (European Institute of Oncology, Milan, Italy; Paris Breast Center, Paris, France; and Leon Berard Centre, Lyon, France) for a multicenter study. A collective chart review of all lipofilling procedures after breast cancer treatment was performed. From 2000 to 2010, the authors reviewed 646 lipofilling procedures from 513 patients. There were 370 mastectomy patients and 143 breast-conserving surgery patients. There were 405 patients (78.9 percent) with invasive carcinoma and 108 (21.1 percent) with carcinoma in situ. The average interval between oncologic surgical interventions and lipofilling was 39.7 months. Average follow-up after lipofilling was 19.2 months. The authors observed a complication rate of 2.8 percent (liponecrosis, 2.0 percent). Twelve radiologic images appeared after lipofilling in 119 breast-conserving surgery cases (10.1 percent). The overall oncologic event rate was 5.6 percent (3.6 percent per year). The locoregional event rate was 2.4 percent (1.5 percent per year). Lipofilling after breast cancer treatment leads to a low complication rate and does not affect radiologic follow-up after breast-conserving surgery. A prospective clinical registry including high-volume multicenter data with a long follow-up is warranted to demonstrate the oncologic safety. Until then, lipofilling should be performed in experienced hands, and a cautious oncologic follow-up protocol is advised. Therapeutic, IV [corrected].

Purpose: To evaluate the cosmetic results of sequential vs. concurrent adjuvant chemotherapy with radiotherapy after breast-conserving surgery for breast cancer, and to compare ratings by patients and physicians. Methods and Materials: From 1996 to 2000, 716 patients with Stage I-II breast cancers were included in a multicenter, Phase III trial (the ARCOSEIN study) comparing, after breast-conserving surgery with axillary dissection, sequential treatment with chemotherapy first followed by radiotherapy vs. chemotherapy administered concurrently with radiotherapy. Cosmetic results with regard to both the overall aspect of the breast and specific changes (color, scar) were evaluated in a total of 214 patients (107more » in each arm) by means of questionnaires to both the patient and a physician whose rating was blinded to treatment allocation. Results: Patients' overall satisfaction with cosmesis was not statistically different between the two arms, with approximately 92% with at least satisfactory results (p = 0.72), although differences between the treated and untreated breasts were greater after the concurrent regimen (29% vs. 14% with more than moderate differences; p 0.0015). Physician assessment of overall cosmesis was less favorable, with lower rates of at least satisfactory results in the concurrent arm (60% vs. 85%; p = 0.001). Consequently, the concordance for overall satisfaction with cosmesis between patients and doctors was only fair ({kappa} = 0.62). Conclusion: After breast-conserving surgery, the concurrent use of chemotherapy with radiotherapy is significantly associated with greater differences between the breasts. These differences do not translate into patients' lessened satisfaction with cosmesis.« less

Traditionally, the treatment options for adolescent idiopathic scoliosis (AIS), the most common form of scoliosis, are exercises; in-patient rehabilitation; braces and surgery. The outcomes of treatments are usually compared with the natural history or observation (non-intervention). The aim of this paper was to provide a synopsis of all treatment options in the light of evidence based practice (EBP). A systematic review was carried out using the most encompassing databases available. Literature has been searched for the outcome parameter ''rate of progression'' and only prospective controlled studies that have considered the treatment versus the natural history have been included. The search strategy included the following terms: ''adolescent idiopathic scoliosis''; ''idiopathic scoliosis''; ''natural history''; ''observation''; ''physiotherapy''; ''physical therapy''; ''rehabilitation''; ''bracing''; ''orthotics'' and ''surgery''. Prospective short-term studies have been found to support outpatient physiotherapy. One prospective controlled study was found to support scoliosis in-patient rehabilitation (SIR). One prospective multi-centre study, a long-term prospective controlled study and a meta-analysis have been found to support bracing. No controlled study, neither short, mid nor long-term, was found to reveal any substantial evidence to support surgery as a treatment for this condition. There is some evidence supporting the conservative treatment for AIS. No substantial evidence has been found in terms of prospective controlled studies to support surgical intervention. In light of the unknown long-term effects of surgery, a randomised controlled trial (RCT) seems necessary. Due to the presence of evidence to support conservative treatments, a plan to compose a RCT for conservative treatment options seems unethical. But it is also important to conclude that the evidence for conservative treatments is weak in number and length.

Aspirin sensitivity, asthma, and chronic sinusitis with polyposis comprises the syndrome of Aspirin Triad (AT). The sinusitis associated with this disease is often fulminate and difficult to treat. In order to evaluate the surgical treatment of chronic sinusitis of AT a 17-year retrospective study of 80 patients was performed. Friedman Class III or IV sinus CT scans were present in 73 patients (90%) preoperatively. Twenty-five patients (30.1%) had steroid-dependent asthma and an additional 40 (50%) required intermittent oral steroids for asthma control. All patients underwent bilateral sinus surgery by either a conservative or a radical approach. Patients were followed from 3 weeks to 16 years postoperatively, with an average followup of 3 years. Sixty-eight patients (85%) had significant improvement in their sinus symptoms and 67 (83%) had relief of their asthma. The eight patients (10%) who remained steroid dependent required smaller doses of steroids. Seven patients (8.8%) had nonoperative orbital complications. There was a significant incidence of revision surgery after both conservative and radical sinus procedures. We conclude that surgical treatment by either a conservative or a radical approach controlled the sinusitis in the majority of AT patients, but neither was effective in eliminating the need for subsequent sinus surgery in a significant number of patients with severe sinus disease (Classes III and IV). Control of the sinus disease has a definite beneficial effect on steroid dependency and the need for intermittent oral steroids in managing the asthma in AT. We recommend conservative surgery in the surgical treatment of these patients. AT patients also require close long-term followup with intense medical management of their chronic respiratory inflammation that appears to put them at increased risk for nonoperative complications of their severe sinusitis.

Blood product usage is a quality outcome for patients undergoing cardiac surgery. To address an increase in blood product usage since the discontinuation of aprotinin, blood conservation strategies were initiated at a tertiary hospital in Oakland, CA. Improving transfusion rates for open heart surgery patients requiring Cardiopulmonary bypass (CPB) involved multiple departments in coordination. Specific changes to conserve blood product usage included advanced CPB technology upgrades, and precise individualized heparin dose response titration assay for heparin and protamine management. Retrospective analysis of blood product usage pre-implementation, post-CPB changes and post-Hemostasis Management System (HMS) implementation was done to determine the effectiveness of the blood conservation strategies. Statistically significant decrease in packed red blood cells, fresh frozen plasma, cryoprecipitate, and platelet usage over the stepped implementation of both technologies was observed. New oxygenator and centrifugal pump technologies reduced active circuitry volume and caused less damage to blood cells. Individualizing heparin and protamine dosing to a patient using the HMS led to transfusion reductions as well. Overall trends toward reductions in hospital length of stay and intensive care unit stay, and as a result, blood product cost and total hospitalization cost are positive over the period of implementation of both CPB circuit changes and HMS implementation. Although they are multifactorial in nature, these trends provide positive enforcement to the changes implemented.

Cervical radiculopathy is a common disease that affects millions of people. Patients usually are managed by conservative therapy and surgical treatments. To compare the clinical outcomes between cervical disc arthroplasty (CDA) and conservative management for patients with single level cervical radiculopathy at C5/6. Seventy-two patients with cervical radiculopathy that only affect C5/6 joints were included and thirty-two of them received CDA surgery, and forty patients were treated with conservative management. All the patients were followed up around 4 years. Cervical curvature, cervical range of motion (CROM), horizontal displacement of cervical spine, and intervertebral gap were measured by radiological examination. All the patients have comparable disease severity based on pre-surgical radiological assessments. At the 4-year follow-up examination, patients with CDA surgery had less CROM at C5/6 level, while greater CROM at C4/5 level, than control group. Similarly, the horizontal displacement in CDA group decreased at C5/6 vertebrae, and increased at C4/5 level at the 4-year follow-up examination. The intervertebral gaps of patients in CDA group were larger than control group at one-year and last follow-up examination. CDA surgery stabilized C5/6 vertebrae and increased the CROM and horizontal displacement of upper adjacent C4/5 vertebrae. Copyright © 2018. Published by Elsevier Ltd.

Little is known about the psychological prerequisites for weight loss maintenance after bariatric surgery. A first step in investigating whether existing knowledge of conservative weight loss treatment is applicable for lifestyle interventions postoperatively is to compare specific psychological characteristics at baseline. The aim of this study was to compare patients scheduled for bariatric surgery with patients receiving conservative treatment for morbid obesity on measures of behavioral and psychosocial characteristics considered predictors of their adoption of and adherence to long-term lifestyle recommendations. Baseline clinical and questionnaire data from the prospective "Oslo Bariatric Surgery Study" were used to examine potential differences between bariatric surgery patients (n = 301) and patients receiving conservative weight loss treatment (n = 261). The surgical group was characterized by their younger age (43.8 vs. 46.2 years, p <0.01), higher percentage of women (79.1 vs. 70.1 %, p <0.05), and higher Body Mass Index (BMI; 45.0 vs. 41.9 kg/m(2), p <0.001). A multiple logistic regression analysis, adjusting for group differences in BMI, gender, and age, showed that the surgical group had higher self-efficacy (Odds ratio; OR = 3.44, 95 % Confidence interval; CI 1.65, 7.14), more positive outcome expectations (OR = 1.53, 95 % CI 1.23, 1.89), and plans that were more explicit for changing their eating behaviors (OR = 1.80, 95 % CI 1.06, 1.93). The surgical patients were also less ready to change physical activity levels (OR = 0.59, 95 % CI 0.48, 0.73), had tried more types of unhealthy weight loss methods in the past (OR = 1.16, 95 % CI 1.01, 1.33), drank soda more frequently (OR = 1.24, 95 % CI 1.02, 1.50), had fewer binge eating episodes (OR = 0.38, 95 % CI 0.20, 0.71), and had more depressive symptoms (OR = 1.19, 95 % CI 1.09, 1.29). Patients opting for bariatric surgery had more positive expectations of the treatment outcomes and stronger beliefs in their ability to achieve these outcomes. Those starting conservative treatment had stronger beliefs in readiness to change physical activity levels. Future studies should explore the effect of interventions for bariatric surgery patients, promoting postoperative physical activity and stress realistic outcome expectations. The potential effects of incorporating this knowledge in intervention strategies remain to be explored.

Purpose The role of surgery in the management of diverticular disease after an episode of acute diverticulitis (AD) managed in a conservative form is evolving. Age, number of episodes of AD, type of episode, and symptoms after the episodes are factors related to the need for elective surgery. The aim of this study is to evaluate the safety of conservative management and the risk factors for emergency surgery after a first episode of AD managed without surgery. Methods We retrospectively evaluated 405 patients diagnosed as having had a first episode of AD. Sixty-nine patients underwent emergency surgery on the first admission, and 69 patients had an elective operation in the follow-up (group A). The remaining 267 patients were managed initially without surgery (group B). Thirteen of these 267 patients needed a further urgent surgical procedure. Factors involved in the decision of elective surgery and the probability of emergency surgery after the first episode of AD managed without surgery were evaluated in relation to demographic factors, risk factors, presence of recurrences, and type of the first episode. Results Patients, mean age was 62.7 years, 71 were aged less than 51, and 151 were males. The mean follow-up for patients with nonoperative management was 91.2 months. An elective operation was performed in 69 patients. Compared to patients in group B, those in group A more frequently had a first episode of complicated acute diverticulitis (CAD) (37.1% vs. 16.4%; P = 0.000) and were more likely to be smokers (46.3% vs. 19.3%; P = 0.000) and to suffer more than one episode of AD (42% vs. 26.9%; P = 0.027). Nonoperative management was chosen for 267 patients, but 13 patients needed an emergency operation later. In the multivariate analysis, we found a significant relation between the presence of CAD in the first episode and the need for emergency surgery. There were no differences in surgical mortality between the patients in the two groups, but patients treated with elective surgery had a higher rate of stoma than patients treated non-operatively (7.2% vs. 1.4%; P = 0.028); this difference was not observed in the subgroup of patients with CAD (15.3% vs. 6.8%; P = 0.458). Conclusion After an episode of AD, nonoperative management is safe because fewer than 5% of patients will need an emergent procedure in a subsequent attack of AD. A first episode of CAD is the only risk factor for emergency surgery in patients managed conservatively. PMID:25360428

Despite the safety and popularity of oncoplastic surgery, there is limited data examining utilization and barriers associated with its incorporation into practice. This study examines the use of oncoplastic techniques in breast conserving surgery and determines the barriers associated with their implementation. A 13-item survey was mailed to all registered general surgeons in Ontario, Canada. The survey assessed surgeon demographics, utilization of specific oncoplastic techniques, and perceived barriers. A total of 234 survey responses were received, representing a response rate of 32.2 % (234 of 725). Of the respondents, 166 surgeons (70.9 %) reported a practice volume of at least 25 % breast surgery. Comparison was made between general surgeons performing oncoplastic breast surgery (N = 79) and those who did not use these techniques (N = 87). Surgeon gender, years in practice, fellowship training, and access to plastic surgery were similar across groups. Both groups rated the importance of breast cosmesis similarly. General surgeons with a practice volume involving >50 % breast surgery were more likely to use oncoplastic techniques (OR 8.82, p < .001) and involve plastic surgeons in breast conserving surgery (OR 2.21, p = .02). For surgeons not performing oncoplastic surgery, a lack of training and access to plastic surgeons were identified as significant barriers. For those using oncoplastic techniques, the absence of specific billing codes was identified as a limiting factor. Lack of training, access to plastic surgeons, and absence of appropriate reimbursement for these cases are significant barriers to the adoption of oncoplastic techniques.

Bologna Guidelines for Diagnosis and Management of Adhesive Small Bowel Obstruction (ASBO): 2010 Evidence-Based Guidelines of the World Society of Emergency Surgery

PubMed Central

2011-01-01

Background There is no consensus on diagnosis and management of ASBO. Initial conservative management is usually safe, however proper timing for discontinuing non operative treatment is still controversial. Open surgery or laparoscopy are used without standardized indications. Methods A panel of 13 international experts with interest and background in ASBO and peritoneal diseases, participated in a consensus conference during the 1st International Congress of the World Society of Emergency Surgery and 9th Peritoneum and Surgery Society meeting, in Bologna, July 1-3, 2010, for developing evidence-based recommendations for diagnosis and management of ASBO. Whenever was a lack of high-level evidence, the working group formulated guidelines by obtaining consensus. Recommendations In absence of signs of strangulation and history of persistent vomiting or combined CT scan signs (free fluid, mesenteric oedema, small bowel faeces sign, devascularized bowel) patients with partial ASBO can be managed safely with NOM and tube decompression (either with long or NG) should be attempted. These patients are good candidates for Water Soluble Contrast Medium (WSCM) with both diagnostic and therapeutic purposes. The appearance of water-soluble contrast in the colon on X-ray within 24 hours from administration predicts resolution. WSCM may be administered either orally or via NGT (50-150 ml) both immediately at admission or after an initial attempt of conservative treatment of 48 hours. The use of WSCM for ASBO is safe and reduces need for surgery, time to resolution and hospital stay. NOM, in absence of signs of strangulation or peritonitis, can be prolonged up to 72 hours. After 72 hours of NOM without resolution surgery is recommended. Patients treated non-operatively have shorter hospital stay, but higher recurrence rate and shorter time to re-admission, although the risk of new surgically treated episodes of ASBO is unchanged. Risk factors for recurrences are age <40 years and matted adhesions. WSCM does not affect recurrence rates or recurrences needing surgery when compared to traditional conservative treatment. Open surgery is the preferred method for surgical treatment of strangulating ASBO as well as after failed conservative management. In selected patients and with appropriate skills, laparoscopic approach can be attempted using open access technique. Access in the left upper quadrant should be safe. Laparoscopic adhesiolysis should be attempted preferably in case of first episode of SBO and/or anticipated single band. A low threshold for open conversion should be maintained. Peritoneal adhesions should be prevented. Hyaluronic acid-carboxycellulose membrane and icodextrin can reduce incidence of adhesions. Icodextrin may reduce the risk of re-obstruction. HA cannot reduce need of surgery. PMID:21255429

Breast conservation in locally advanced breast cancer in developing countries: wise or waste.

PubMed

Tewari, Mallika; Krishnamurthy, Arvind; Shukla, Hari S

2009-03-01

Breast conservation as an additional benefit was beyond the initial expectations of the investigators who pioneered neoadjuvant chemotherapy (NACT). In recent years an increasing number of patients with locally advanced breast cancer (LABC) are being treated with NACT, followed by breast conservation surgery with axillary dissection and radiation as a part of the multimodality management. Breast conservation has not been the standard of care for women with LABC, owing to concerns of increased chances of local recurrence, and possible survival disadvantage and psychological trauma from experiencing a recurrence of malignancy. LABC is still a common form of presentation of breast cancer in developing countries. Strict adherence to treatment protocols and regular follow-ups for years may not be practical for a large majority of patients hailing from the regions most affected by LABC. Defaulters often thus have a heavy price to pay. Hence lies the importance of carefully selecting LABC patients for a breast conservation approach from others that would have a higher risk of locoregional recurrence. Can we extrapolate the lessons learnt in early breast cancer to LABC and offer selected patients with LABC breast conservation therapy? Would the local control and survival results with conservative therapy be comparable to those obtained using mastectomy, or does the increased tumor burden in LABC necessitate ablative surgery in all women? This review aims to address these important questions.

Evidence is limited for outcomes of surgical versus conservative management for patients with cervical esophageal or hypopharyngeal perforations. Patients with cervical esophageal or hypopharyngeal perforations treated between 1994 and 2014 were identified using an institutional database. Outcomes were compared between patients who underwent operative drainage and those who had conservative management with broad-spectrum antibiotics and withholding oral intake. Twenty-eight patients were identified with hypopharyngeal or cervical esophageal perforations, mostly due to iatrogenic (nasogastric tube placement, endoscopy, endotracheal intubation) injuries (68%). Fourteen were treated initially with conservative management and 14 with initial surgery. Six patients failed conservative treatment and two patients failed surgical treatment. Patients managed conservatively who had eaten between injury and diagnosis (p=0.003), those who had 24 hours or more between the time of injury and diagnosis (p=0.026), and those who showed signs of systemic toxicity (p=0.001) were significantly more likely to fail conservative treatment and require surgery. No variables were significant for treatment failure in the surgical group. Of the 20 patients who ultimately underwent a surgical procedure, two required a second procedure. Patients who have eaten between the time of perforation and diagnosis, have 24 hours or more between injury and diagnosis, and those that show signs of systemic toxicity are at higher risk of failing conservative management and surgical drainage should be considered. For patients without these risk factors, a trial of conservative management can be attempted. Copyright © 2015 Elsevier Inc. All rights reserved.

Management of Spinal Deformities and Evidence of Treatment Effectiveness

Introduction: The review evaluates the up-to-date evidence for the treatment of spinal deformities, including scoliosis and hyperkyphosis in adolescents and adults. Material and Methods: The PubMed database was searched for review articles, prospective controlled trials and randomized controlled trials related to the treatment of spinal deformities. Articles on syndromic scoliosis were excluded and so were the articles on hyperkyphosis of the spine with causes other than Scheuermann’s disease and osteoporosis. Articles on conservative and surgical treatments of idiopathic scoliosis, adult scoliosis and hyperkyphosis were also included. For retrospective papers, only studies with a follow up period exceeding 10 years were included. Results: The review showed that early-onset idiopathic scoliosis has a worse outcome than late-onset idiopathic scoliosis, which is rather benign. Patients with AIS function well as adults; they have no more health problems when compared to patients without scoliosis, other than a slight increase in back pain and aesthetic concern. Conservative treatment of adolescent idiopathic scoliosis (AIS) using physiotherapeutic scoliosis-specific exercises (PSSE), specifically PSSR and rigid bracing was supported by level I evidence. Yet to date, there is no high quality evidence (RCT`s) demonstrating that surgical treatment is superior to conservative treatment for the management of AIS. For adult scoliosis, there are only a few studies on the effectiveness of PSSEs and a conclusion cannot as yet be drawn. For hyperkyphosis, there is no high-quality evidence for physiotherapy, bracing or surgery for the treatment of adolescents and adults. However, bracing has been found to reduce thoracic hyperkyphosis, ranging from 55 to 80° in adolescents. In patients over the age of 60, bracing improves the balance score, and reduces spinal deformity and pain. Surgery is indicated in adolescents and adults in the presence of progression of kyphosis, refractory pain and loss of balance. Discussion: The available evidence reviewed has suggested that different approaches are needed towards the management of different spinal deformities. Specific exercises should be prescribed in children and adolescents with a Cobb angle in excess of 15°. In progressive curves, they should be used in conjunction with bracing. Clarity regarding differences and similarities is given as to what makes PSSE and PSSR specific exercises. As AIS is relatively benign in nature, conservative treatment should be tried when the curve is at a surgical threshold, before surgery is considered. Similarly, bracing and exercises should be prescribed for patients with hyperkyphosis, particularly when the lumbar spine is afflicted. Surgery should be considered only when the symptoms cannot be managed conservatively. Conclusion: There is at present high quality evidence in support of the conservative treatment of AIS. The current evidence supports the use of PSSE, especially those using PSSR, together with bracing in the treatment of AIS. In view of the lack of medical consequences in adults with AIS, conservative treatment should be considered for curves exceeding the formerly assumed range of conservative indications. There is, however a lack of evidence in support of any treatment of choice for hyperkyphosis in adolescents and spinal deformities in adults. Yet, conservative treatment should be considered first. Yet to date, there is no high quality evidence (RCT`s) demonstrating that surgical treatment is superior to conservative treatment for the management of AIS and hyperkyphosis. Additionally, surgery needs to be considered with caution, as it is associated with a number of long-term complications. PMID:29399227

259 Patients with DCIS of the breast applying USC/Van Nuys prognostic index: a retrospective review with long term follow up.

The Van Nuys Prognostic Index (VNPI) is a simple score for predicting the risk of local recurrence (LR) in patients with Ductal Carcinoma In Situ (DCIS) conservatively treated. This score combines three independent predictors of Local Recurrence. The VNPI has recently been updated with the addition of age as a fourth parameter into the scoring system (University of Southern California/ VNPI). Our database consisted of 408 women with DCIS. Applying the USC/VNPI we reviewed retrospectively 259 patients who were treated with breast conserving surgery with or without radiotherapy (RT). Of these patients 63.5% had a low VNPI score, 32% intermediate and 4.5% a high score. In the low score group, the majority of the patients underwent Conservative Surgery (CS) without RT while in the intermediate group, almost half of the patients received RT. Eighty-three percent (83%) of the patients with high VNPI were treated with Conservative Surgery plus RT. Nodal assessment by Sentinel Lymph Node Biopsy was obtained in 32 patients since 2002. Twenty-one Local Recurrences were observed (8%) with a mean follow up of 130 months: sixteen were invasive. No statistically significant differences in Disease Free Survival were reached in all groups of VNPI score between patients treated with Conservative Surgery or Conservative Surgery plus RT. However it was noted that the higher the VNPI score, the lower was the risk of local recurrence in the group treated additionally with RT, even though it was not statistically significant. Further analysis included those patients treated with Conservative Surgery alone and followed up. Disease-free survival (DFS) at 10 years was 94% with low VNPI and 83% in both intermediate and high score (P < 0.05). No significant differences were observed in the subgroups of VNPI. The Local Relapse rate after Conservative Surgery alone, increased with tumor size, margin width, and pathology classification (P < 0,05), while age was not found to be a significant factor. Lesions with only mammographic appearances are associated with lower DFS but it did not reach significance (P = ns), while assumption of estrogenic hormones and familial history of breast cancer are significant factors associated with a higher risk of local recurrence. After multivariate analysis including seven clinical and pathological factors, the only significant predictors of local recurrence remained margin width of surgical excision, previous therapy with estrogens (contraceptives or Hormone Replacement Therapy) and the Van Nuys pathologic classification. The overall survival breast cancer specific was 99% and no differences were observed between groups (P = ns). The comparison of patients treated with a total mastectomy and those conservatively treated showed a significantly better local relapse free survival rate obtained with mastectomy (98.2% vs. 89.7% at 10 years P = 0.02). However, the overall cause-specific survival did not prove any better outcome (98.7% in both groups). Of the 32 patients who underwent a Sentinel Lymph Node Biopsy, four were found to have micrometastases and all of them had a previous Directional Vacuum Assisted Biopsy. Although in our series there is not a significant difference in LR rates by the parameter of age, the new USC/VNPI is still a simple and reliable scoring system for therapeutic management of DCIS. We did not find any statistically significant advantage in groups treated with the addition of RT. Obtaining wide surgical margins appears to be the strongest prognostic factor for local recurrence, regardless of other pathological factors or the addition of adjuvant radiation therapy. However, only prospective randomized studies can precisely predict the risk of LR of conservatively treated DCIS. The clinical significance of Sentinel Lymph Nodes micrometastases Immuno-Histo-Chemistry-detected found in DCIS patients remains uncertain. However, we hypothesize that the anatomical disruption after preoperative biopsy procedures increases the likelihood of epithelial cell displacement and the frequency of IHC-positive Sentinel Lymph Nodes, both of which are directly proportional to the degree of manipulation.

68 cases of glottic carcinomas (T1 53 and T2 15 cases) treated with CO2 laser or KTP/532 laser April 1982 through March 1992 were reviewed. The patients were followed up from 13 to 130 months (mean 60 months). The 3-year determinate survival rate was 100% and 5-year determinate survival rate was 100% for T1 and 80% for T2. The voice conservation rate was 97% for T1a, 83% for T1b, and 80% for T2 and vocal function was satisfactorily preserved for daily life. The results led to the following conclusions: (1) Glottic T1 carcinomas can be treated by laser surgery alone. (2) Lesions involving the anterior commissure can be treated by laser excision and vaporization. (3) Laser surgery followed by external radiation therapy for glottic T2 carcinomas improves the voice conservation rate.

The purpose of this work is to develop an anatomically and mechanically representative breast phantom for the validation of breast conserving surgical therapies, specifically, in this case, image guided surgeries. Using three patients scheduled for lumpectomy and four healthy volunteers in mock surgical presentations, the magnitude, direction, and location of breast deformations was analyzed. A phantom setup was then designed to approximate such deformations in a mock surgical environment. Specifically, commercially available and custom-built polyvinyl alcohol (PVA) phantoms were used to mimic breast tissue during surgery. A custom designed deformation apparatus was then created to reproduce deformations seen in typical clinical setups of the pre- and intra-operative breast geometry. Quantitative analysis of the human subjects yielded a positive correlation between breast volume and amount of breast deformation. Phantom results reflected similar behavior with the custom-built PVA phantom outperforming the commercial phantom.

Atrial flutter after surgical maze: incidence, diagnosis, and management.

The prevalence of atrial fibrillation is increasing and surgical ablation is becoming more common, both as a stand-alone procedure and when performed concomitantly with other cardiac surgery. Although surgical ablation is effective, with it unique challenges arise, including iatrogenic macroreentrant tachycardias that are often highly symptomatic and difficult to manage conservatively. Postsurgical ablation, localization of the arrhythmic circuit is difficult to determine using surface ECG alone because of alterations in the atrial myocardium, and multiple different pathways are often present. Most, however, localize to the left atrium, and percutaneous catheter ablation is emerging as an effective treatment modality. Patients with complex postoperative arrhythmias should be referred to a dedicated atrial fibrillation center when possible and symptomatic arrhythmias mapped and ablated. Knowledge of the previously performed surgical lesion set is of vital importance in understanding the mechanism of the arrhythmia and increasing procedural success rates. http://links.lww.com/HCO/A31.

Objective To explore how underlying disability affects treatments and outcomes of disabled women with breast cancer. Data Sources Surveillance, Epidemiology, and End Results program data, linked with Medicare files and Social Security Administration disability group. Study Design Ninety thousand two hundred and forty-three incident cases of early-stage breast cancer under age 65; adjusted relative risks and hazards ratios examined treatments and survival, respectively, for women in four disability groups compared with nondisabled women. Principal Findings Demographic characteristics, treatments, and survival varied among four disability groups. Compared with nondisabled women, those with mental disorders and neurological conditions had significantly lower adjusted rates of breast conserving surgery and radiation therapy. Survival outcomes also varied by disability type. Conclusions Compared with nondisabled women, certain subgroups of women with disabilities are especially likely to experience disparities in care for breast cancer. PMID:18479411

Conservative treatment for breast cancer. Complications requiring reconstructive surgery

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

Bostwick, J. 3d.; Paletta, C.; Hartrampf, C.R.

Women who select conservative treatment for carcinoma of the breast (tumor excision followed by supervoltage radiation therapy) place a premium on breast preservation and aesthetics. When local control fails and they require a mastectomy, or when the aesthetic appearance is unacceptable, they may request breast reconstruction. The goal of this study is to evaluate a series of 10 patients who required reconstructive breast surgery after complications of conservative treatment. Patient classification: I. Breast or chest wall necrosis (3). II. Breast fibrosis and gross asymmetry (3). III. Local recurrence of breast cancer (5). IV. Positive margins after the initial lumpectomy (1).more » The mean age was 34 years. Radiation dosage average was 5252 rads with two patients receiving iridium-192 implant boosts. The reconstructive management was complex and usually required a major musculocutaneous flap because of the radiation effects.« less

The standard treatment for muscle-invasive bladder cancer is surgical removal of the bladder and construction of a neobladder. Recently, important improvements have been made in the potential for bladder-conserving treatment using radiotherapy. External beam radiotherapy has undergone technological improvements, as a result of which it is possible to radiate the tumour more precisely while decreasing radiation to healthy tissue. Radiochemotherapy improves local recurrence-free and overall survival compared with radiotherapy alone. The results of this combined treatment are comparable with those of surgery. Additionally, Dutch radiotherapy departments have collected data in a national database of 1040 selected patients with confined bladder cancer. These patients were treated with external beam radiation, limited surgery and brachytherapy. The 5-year local recurrence-free survival was 75%. Bladder conserving treatment options for muscle-invasive bladder cancer should be discussed during the multidisciplinary meeting.

Persistent air leaks: a review with an emphasis on bronchoscopic management

PubMed Central

Lazarus, Donald R.

2017-01-01

Persistent air leak (PAL) is a cause of significant morbidity in patients who have undergone lung surgery and those with significant parenchymal lung disease suffering from a pneumothorax. Its management can be complex and challenging. Although conservative treatment with chest drain and observation is usually effective, other invasive techniques are needed when conservative treatment fails. Surgical management and medical pleurodesis have long been the usual treatments for PAL. More recently numerous bronchoscopic procedures have been introduced to treat PAL in those patients who are poor candidates for surgery or who decline surgery. These techniques include bronchoscopic use of sealants, sclerosants, and various types of implanted devices. Recently, removable one-way valves have been developed that are able to be placed bronchoscopically in the affected airways, ameliorating air-leaks in patients who are not candidates for surgery. Future comparative trials are needed to refine our understanding of the indications, effectiveness, and complications of bronchoscopic techniques for treating PAL. The following article will review the basic principles of management of PAL particularly focusing on bronchoscopic techniques. PMID:29268535

Basic fibroblast growth factor (bFGF) promotes the regeneration of denervated nerves. The aim of this study was to evaluate the regeneration-facilitating effects of novel facial nerve decompression surgery using bFGF in a gelatin hydrogel in patients with severe Bell palsy. Prospective clinical study. Tertiary referral center. Twenty patients with Bell palsy after more than 2 weeks following the onset of severe paralysis were treated with the new procedure. The facial nerve was decompressed between tympanic and mastoid segments via the mastoid. A bFGF-impregnated biodegradable gelatin hydrogel was placed around the exposed nerve. Regeneration of the facial nerve was evaluated by the House-Brackmann (H-B) grading system. The outcomes were compared with the authors' previous study, which reported outcomes of the patients who underwent conventional decompression surgery (n = 58) or conservative treatment (n = 43). The complete recovery (H-B grade 1) rate of the novel surgery (75.0%) was significantly better than the rate of conventional surgery (44.8%) and conservative treatment (23.3%). Every patient in the novel decompression surgery group improved to H-B grade 2 or better even when undergone between 31 and 99 days after onset. Advantages of this decompression surgery are low risk of complications and long effective period after onset of the paralysis. To the authors' knowledge, this is the first clinical report of the efficacy of bFGF using a new drug delivery system in patients with severe Bell palsy.

Impact of using DSM-5 criteria for diagnosing binge eating disorder in bariatric surgery candidates: change in prevalence rate, demographic characteristics, and scores on the Minnesota Multiphasic Personality Inventory--2 restructured form (MMPI-2-RF).

Binge eating disorder (BED) was recently included in the DSM-5. The prevalence rate for BED using the DSM-IV-TR research criteria tends to be higher in bariatric surgery candidates than the normative population; however, no studies have examined how many more bariatric surgery candidates will meet the new, less conservative criteria of DSM-5. We explore the current BED prevalence rate change in a sample of bariatric surgery candidates. Data were obtained for 1,283 bariatric surgery candidates. 84 men and 213 women were diagnosed with current BED using DSM-IV-TR research criteria. A semi-structured interview, the binge eating scale (BES), and a Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF) were given to every patient as part of standard procedures mandated by the facility. An additional 3.43% (p < .001) of bariatric surgery candidates met the diagnostic threshold for BED when using DSM-5 criteria. These individuals were demographical similar and produced similar MMPI-2-RF and BES scores when compared with patients who met DSM-IV-TR criteria for BED. Thus, the current investigation indicates that individuals meeting BED criteria based on DSM-5 are similar to those meeting the more conservative diagnostic threshold outlined in DSM-IV-TR in a sample of bariatric surgery candidates. © 2014 Wiley Periodicals, Inc.

To analyze medical practice variation in breast cancer surgery (either inpatient-based or day-case surgery), by comparing conservative surgery (CS) plus radiotherapy vs. non-conservative surgery (NCS). We also analyzed the opportunity costs associated with CS and NCS. We performed an observational study of age- and sex-standardized rates of CS and NCS, performed in 199 Spanish healthcare areas in 2008-2009. Costs were calculated by using two techniques: indirectly, by using All-Patients Diagnosis Related Groups (AP-DRG) based on hospital admissions, and directly by using full costing from the Spanish Network of Hospital Costs (SNHC) data. Standardized surgery rates for CS and NCS were 6.84 and 4.35 per 10,000 women, with variation across areas ranging from 2.95 to 3.11 per 10,000 inhabitants. In 2009, 9% of CS was performed as day-case surgery, although a third of the health care areas did not perform this type of surgery. Taking the SNHC as a reference, the cost of CS was estimated at 7,078 € and that of NCS was 6,161 €. Using AP-DRG, costs amounted to 9,036 € and 8,526 €, respectively. However, CS had lower opportunity costs than NCS when day-case surgery was performed frequently-more than 46% of cases (following SNHC estimates) or 23% of cases (following AP-DRG estimates). Day-case CS for breast cancer was found to be the best option in terms of opportunity-costs beyond a specific threshold, when both CS and NCS are elective. Copyright © 2013 SESPAS.

Objectives This study compared persistent breast pain among women who received breast-conserving surgery for breast cancer and women without a history of breast cancer. Methods Breast cancer survivors (n=200) were recruited at their first post-surgical surveillance mammogram (6-15 months post-surgery). Women without a breast cancer history (n=150) were recruited at the time of a routine screening mammogram. All women completed measures of breast pain, pain interference with daily activities and intimacy, worry about breast pain, anxiety symptoms, and depression symptoms. Demographic and medical information were also collected. Results Persistent breast pain (duration ≥ 6 months) was reported by 46.5% of breast cancer survivors and 12.7% of women without a breast cancer history (p<0.05). Breast cancer survivors also had significantly higher rates of clinically significant persistent breast pain (pain intensity score ≥3/10), as well as higher average breast pain intensity and unpleasantness scores. Breast cancer survivors with persistent breast pain had significantly higher levels of depressive symptoms, as well as pain worry and interference, compared to survivors without persistent breast pain or women without a breast cancer history. Anxiety symptoms were significantly higher in breast cancer survivors with persistent breast pain compared to women without a breast cancer history. Discussion Results indicate that persistent breast pain negatively impacts women with a history of breast conserving cancer surgery compared to women without that history. Strategies to ameliorate persistent breast pain and to improve adjustment among women with persistent breast pain should be explored for incorporation into standard care for breast cancer survivors.

An adhesive small bowel obstruction (ASBO) is generally caused by postoperative adhesions and is more frequently associated with colorectal surgeries than other procedures. We compared the outcomes of operative and conservative management of ASBO after primary colorectal cancer surgery.We retrospectively reviewed 5060 patients who underwent curative surgery for primary colorectal cancer; 388 of these patients (7.7%) were readmitted with a diagnosis of SBO. We analyzed the clinical course of these patients with reference to the cause of their surgery.Of the 388 SBO patients analyzed, 170 were diagnosed with ASBO. Their 3-, 5-, and 7-year recurrence-free survival rates were 86.1%, 72.8%, and 61.5%, respectively. The median follow-up period was 59.2 months. Repeated conservative management for ASBO without surgical management led to higher recurrence rates: 21.0% after the first admission, 41.7% after the second, 60.0% after the third, and 100% after the fourth (P = .006). Surgical management was needed for 19.2%, 22.2%, 50%, and 66.7% of patients admitted with ASBO on the first to fourth hospitalizations, respectively. Repeated hospitalization for obstruction led to a greater possibility of surgical management (P = .001). Of 27 patients with surgical management at the first admission, 6 (17.6%) were readmitted with a diagnosis of SBO, but there were no further episodes of SBO in the surgically managed patients.Patients who undergo operative management for ASBO have a reduced risk of recurrence requiring hospitalization, whereas those with repeated conservative management have an increased risk of recurrence and require operative management. Operative management should be considered for recurrent SBO.

Surgery appears to be the best treatment option for a chronic fistula after laparoscopic sleeve gastrectomy (LSG). Conservative procedures (conversion into a Roux-en-Y gastric bypass, Roux-limb placement) have proven their feasibility and efficacy, but an open total gastrectomy (TG) is sometimes required in challenging situations. To assess outcomes from 12 consecutive patients who underwent surgery for a post-sleeve gastrectomy chronic fistula (PSGCF) between January 2004 and February 2012. University public hospital, France. Patients with a PSGCF who underwent surgery were included in this retrospective study. Mortality, morbidity (i.e., Clavien-Dindo score), weight loss, and nutritional status were assessed. Twelve of 57 patients (21%) with a post-LSG leak developed a PSGCF. There were 3 men (25%). Mean age was 39±9 years and mean preoperative body mass index was 35±5 kg/m 2 . All 12 patients underwent an open total gastrectomy with an esojejunostomy (TG). Conservative procedures were considered but not possible. The mean follow-up period was 38±11 months. The mean delay between LSG and TG was 12±6 months. Intraoperative discovery of multiple (>2) gastric fistulas was reported in 9 patients (75%). There were no deaths, but morbidity rate was 50%. Early postoperative fistula occurred in 3 patients (anastomosis n = 1, duodenal stump n = 2). None of these patients required further surgery. The median healing time of the fistula was 37 days (range 24-53). Promising results from weight loss and nutritional status were found at the end of the follow-up. A salvage open TG is a well-tolerated and reproducible salvage procedure for cases of a PSGCF, when conservative procedures are not possible. Copyright © 2016 American Society for Bariatric Surgery.

To evaluate the causes, treatment and prevention of esophageal fistulas after anterior cervical spine surgery. Between January 2004 and December 2011, 5 of 2348 patients who underwent anterior cervical surgery in our hospital developed esophageal fistulas (three male and two female patients, average age 34 years). Their diagnoses were cervical injuries (three), cervical spondylosis (one) and cervical tuberculosis (one). Their esophageal fistulas were treated by debridement and exploratory surgery, primary suturing of the perforation and/or sternocleidomastoid myoplasty. If conservative treatment failed or esophageal fistula recurred, plate removal was offered. Postoperative treatment included esophageal rest, enteral nutrition, wound drainage, and antibiotics. Methylene blue was used to evaluate results. An esophageal fistula was discovered during anterior cervical surgery in one patient and primary suturing performed. In four patients, fistulas were diagnosed after anterior cervical decompression and fusion. In one of these, only debridement and exploratory surgery were required. In another, a perforation was sutured during debridement and exploratory surgery. In the third, internal fixation was removed because of failure of prolonged conservative treatment. In the fourth, the esophageal fistula recurred repeatedly; he required removal of the hardware and reinforcement with a sternocleidomastoid muscle flap. At 6-48 months follow-up, all patients were in good condition, symptom free, and without cervical instability or infectious spondylitis. Successful management of esophageal fistula after anterior cervical spinal surgery depends on primary closure of the perforation with or without muscle flaps, surgical drainage, esophageal rest and nutritional support, and removal of hardware if necessary. Prevention consists of careful surgery and gentle tissue handling. © 2012 Tianjin Hospital and Wiley Publishing Asia Pty Ltd.

Breast cancer patients commonly use the internet as an information resource. Our objective was to evaluate the quality of online information available to support patients facing a decision for breast surgery. Breast cancer surgery-related queries were performed (Google and Bing), and reviewed for content pertinent to breast cancer surgery. The DISCERN instrument was used to evaluate websites' structural components that influence publication reliability and ability of information to support treatment decision-making. Scores of 4/5 were considered "good." 45 unique websites were identified. Websites satisfied a median 5/9 content questions. Commonly omitted topics included: having a choice between breast conservation and mastectomy (67%) and potential for 2nd surgery to obtain negative margins after breast conservation (60%). Websites had a median DISCERN score of 2.9 (range 2.0-4.5). Websites achieved higher scores on structural criteria (median 3.6 [2.1-4.7]), with 24% rated as "good." Scores on supporting decision-making questions were lower (2.6 [1.3-4.4]), with only 7% scoring "good." Although numerous breast cancer-related websites exist, most do a poor job providing women with essential information necessary to actively participate in decision-making for breast cancer surgery. Providing easily- accessible, high-quality online information has the potential to significantly improve patients' experiences with decision-making. © 2015 Wiley Periodicals, Inc.

Hallux valgus, ankle osteoarthrosis and adult acquired flatfoot deformity: a review of three common foot and ankle pathologies and their treatments

PubMed Central

Crevoisier, Xavier; Assal, Mathieu; Stanekova, Katarina

2016-01-01

The pathogenesis of hallux valgus deformity is multifactorial. Conservative treatment can alleviate pain but is unable to correct the deformity. Surgical treatment must be adapted to the type and severity of the deformity. Success of surgical treatment ranges from 80% to 95%, and complication rates range from 10% to 30%. Ankle osteoarthrosis most commonly occurs as a consequence of trauma. Ankle arthrodesis and total ankle replacement are the most common surgical treatments of end stage ankle osteoarthrosis. Both types of surgery result in similar clinical improvement at midterm; however, gait analysis has demonstrated the superiority of total ankle replacement over arthrodesis. More recently, conservative surgery (extraarticular alignment osteotomies) around the ankle has gained popularity in treating early- to mid-stage ankle osteoarthrosis. Adult acquired flatfoot deformity is a consequence of posterior tibial tendon dysfunction in 80% of cases. Classification is based upon the function of the tibialis posterior tendon, the reducibility of the deformity, and the condition of the ankle joint. Conservative treatment includes orthotics and eccentric muscle training. Functional surgery is indicated for treatment in the early stages. In case of fixed deformity, corrective and stabilising surgery is performed. Cite this article: Crevoisier X, Assal M, Stanekova K.

The purpose of this study was to evaluate recurrence rates and comorbidity in patients with pleomorphic adenomas of patients after superficial and total conservative parotidectomy. Localization of pleomorphic adenomas, age, sex distribution and facial nerve function of 73 patients were examined in this retrospective study. The recurrence rate could be determined in 43 of these patients. The interval between surgery and last recall varied between 2 and 20 years (median: 8.1 years). Most of the patients were female (67%) with a parotid pleomorphic adenoma. No recurrence was found regard less of whether a superficial or total conservative parotidectomy had been performed. Our data did show that the total conservative parotidectomy is associated with a higher incidence of temporary impaired facial nerve function, which was seen in 42% of this group. Temporary decreased nerve function after superficial parotidectomy was rare being apparent in only 16% of this group. A more radical procedure does not significantly lower the recurrence rate. We suggest that the indication for a total conservative parotidectomy in cases of superficial adenomas should be considered carefully.

Subdural Fluid Collection and Hydrocephalus After Foramen Magnum Decompression for Chiari Malformation Type I: Management Algorithm of a Rare Complication.

Chiari malformation type I is a hindbrain abnormality characterized by descent of the cerebellar tonsils beneath the foramen magnum, frequently associated with symptoms or brainstem compression, impaired cerebrospinal fluid circulation, and syringomyelia. Foramen magnum decompression represents the most common way of treatment. Rarely, subdural fluid collection and hydrocephalus represent postoperative adverse events. The treatment of this complication is still debated, and physicians are sometimes uncertain when to perform diversion surgery and when to perform more conservative management. We report an unusual occurrence of subdural fluid collection and hydrocephalus that developed in a 23-year-old patient after foramen magnum decompression for Chiari malformation type I. Following a management protocol, based on a step-by-step approach, from conservative therapy to diversion surgery, the patient was managed with urgent external ventricular drainage, and then with conservative management and wound revision. Because of the rarity of this adverse event, previous case reports differ about the form of treatment. In future cases, finding clinical and radiologic features to identify risk factors that are useful in predicting if the patient will benefit from conservative management or will need to undergo diversion surgery is only possible if a uniform form of treatment is used. Therefore, we believe that a management algorithm based on a step-by-step approach will reduce the use of invasive therapies and help to create a standard of care. Copyright © 2017 Elsevier Inc.

The present research examined the roles of different forms of peer influence, internalization, social comparison, and body dissatisfaction in men's interest in cosmetic surgery. Participants were 204 Italian men (M age  = 34.02, SD = 11.21). Regression analyses showed that appearance conversations with friends and peer attribution were associated with consideration of cosmetic surgery for social reasons, while teasing on muscularity (but not teasing on general body and shape) was linked to interest in cosmetic surgery for intrapersonal motives. Social comparison was significantly and positively associated with men's interest in cosmetic surgery, while internalization was not. Dissatisfaction with body fat was linked to men's consideration of cosmetic surgery for social motivations, while muscularity and height dissatisfaction did not emerge as significant correlates of cosmetic surgery attitudes. These findings highlight the importance of psychosocial factors, such as peer influence, body fat dissatisfaction, and social comparison in men's interest in cosmetic procedures.

2018-01-01

Evidence-based guidelines on the management of pancreatic cystic neoplasms (PCN) are lacking. This guideline is a joint initiative of the European Study Group on Cystic Tumours of the Pancreas, United European Gastroenterology, European Pancreatic Club, European-African Hepato-Pancreato-Biliary Association, European Digestive Surgery, and the European Society of Gastrointestinal Endoscopy. It replaces the 2013 European consensus statement guidelines on PCN. European and non-European experts performed systematic reviews and used GRADE methodology to answer relevant clinical questions on nine topics (biomarkers, radiology, endoscopy, intraductal papillary mucinous neoplasm (IPMN), mucinous cystic neoplasm (MCN), serous cystic neoplasm, rare cysts, (neo)adjuvant treatment, and pathology). Recommendations include conservative management, relative and absolute indications for surgery. A conservative approach is recommended for asymptomatic MCN and IPMN measuring <40 mm without an enhancing nodule. Relative indications for surgery in IPMN include a main pancreatic duct (MPD) diameter between 5 and 9.9 mm or a cyst diameter ≥40 mm. Absolute indications for surgery in IPMN, due to the high-risk of malignant transformation, include jaundice, an enhancing mural nodule >5 mm, and MPD diameter >10 mm. Lifelong follow-up of IPMN is recommended in patients who are fit for surgery. The European evidence-based guidelines on PCN aim to improve the diagnosis and management of PCN. PMID:29574408

Endocarditis is a rare and serious complication of human brucellosis. The diagnosis is suspected in cases of endocarditis without response to conservative antibiotic treatment and it is confirmed with enzyme-linked immunosorbent assay (ELISA) test, titers being higher than 1:160. The treatment is usually a surgery, followed with antibiotics for long period of time. Some cases can be cured with antibiotic treatment only, with antibiotics such as doxiciclin, rifampicin, ciprofloxacin, gentamicin and tetracycline. We present a case report of a patient with brucellose endocarditis. Fifty one year old male patient, a farmer, was admitted with clinical history of fever and weight loss. Echocardiography showed thickening and vegetation on the aortic valve and blood culture was positive for Staphylococcus epidermidis. The treatment with crystal penicillin and garamycin was initiated with no improval during three weeks. Endocarditis caused by human brucellosis was suspected and a new treatment with rifampicin and ciprofloxacin, associated with vancomycin because of the first blood culture, was initiated. Agglutination sorology was positive for brucellosis, with titers of 1:360. The patient got better with new treatment and was dismissed from the intensive care unit clinically stable, taking ciprofloxacin and gentamicin. Endocarditis caused by human brucellosis is rare; however it should always be considered when conservative antibiotic treatment fails, especially in patients that have contact with animals and dairy products.

We consider a re-analysis of the wait-and-see (control) arm of a recent clinical trial on sciatica. While the original randomised trial was designed to evaluate the public policy effect of a conservative wait-and-see approach versus early surgery, we investigate the impact of surgery at the individual patient level in a re-analysis of the wait-and-see group data. Both marginal structural model re-weighted estimates as well as propensity score adjusted analyses are presented. Results indicate that patients with high propensity to receive surgery may have beneficial effects at 2 years from delayed disc surgery. PMID:25353633

Grassland bird habitat has declined substantially in the United States. Remaining grasslands are increasingly fragmented, mostly privately owned, and vary greatly in terms of habitat quality and protection status. A coordinated strategic response for grassland bird conservation is difficult, largely due to the scope and complexity of the problem, further compounded by biological, sociological, and economic uncertainties. We describe the results from a collaborative Structured Decision Making (SDM) workshop focused on linking social and economic drivers of landscape change to grassland bird population outcomes. We identified and evaluated alternative strategies for grassland bird conservation using a series of rapid prototype models. We modeled change in grassland and agriculture cover in hypothetical landscapes resulting from different landowner decisions in response to alternative socio-economic conservation policy decisions. Resulting changes in land cover at all three stages of the annual cycle (breeding, wintering, and migration) were used to estimate changes in grassland bird populations. Our results suggest that successful grassland bird conservation may depend upon linkages with ecosystem services on working agricultural lands and grassland-based marketing campaigns to engage the public. With further development, spatial models that link landowner decisions with biological outcomes can be essential tools for making conservation policy decisions. A coordinated non-traditional partnership will likely be necessary to clearly understand and systematically respond to the many conservation challenges facing grassland birds.

Grassland bird habitat has declined substantially in the United States. Remaining grasslands are increasingly fragmented, mostly privately owned, and vary greatly in terms of habitat quality and protection status. A coordinated strategic response for grassland bird conservation is difficult, largely due to the scope and complexity of the problem, further compounded by biological, sociological, and economic uncertainties. We describe the results from a collaborative Structured Decision Making (SDM) workshop focused on linking social and economic drivers of landscape change to grassland bird population outcomes. We identified and evaluated alternative strategies for grassland bird conservation using a series of rapid prototype models. We modeled change in grassland and agriculture cover in hypothetical landscapes resulting from different landowner decisions in response to alternative socio-economic conservation policy decisions. Resulting changes in land cover at all three stages of the annual cycle (breeding, wintering, and migration) were used to estimate changes in grassland bird populations. Our results suggest that successful grassland bird conservation may depend upon linkages with ecosystem services on working agricultural lands and grassland-based marketing campaigns to engage the public. With further development, spatial models that link landowner decisions with biological outcomes can be essential tools for making conservation policy decisions. A coordinated non-traditional partnership will likely be necessary to clearly understand and systematically respond to the many conservation challenges facing grassland birds.

[Controversies about instrumented surgery and pain relief in degenerative lumbar spine pain. Results of scientific evidence].

Investigation and development of new techniques for intrumented surgery of the spine is not free of conflicts of interest. The influence of financial forces in the development of new technologies an its immediately application to spine surgery, shows the relationship between the published results and the industry support. Even authors who have defend eagerly fusion techniques, it have been demonstrated that them are very much involved in the revision of new articles to be published and in the approval process of new spinal technologies. When we analyze the published results of spine surgery, we must bear in mind what have been call in the "American Stock and Exchange" as "the bubble of spine surgery". The scientific literature doesn't show clear evidence in the cost-benefit studies of most instrumented surgical interventions of the spine compare with the conservative treatments. It has not been yet demonstrated that fusion surgery and disc replacement are better options than the conservative treatment. It's necessary to point out that at present "there are relationships between the industry and back pain, and there is also an industry of the back pain". Nonetheless, the "market of the spine surgery" is growing up because patients are demanding solutions for their back problems. The tide of scientific evidence seams to go against the spinal fusions in the degenerative disc disease, discogenic pain and inespecific back pain. After decades of advances in this field, the results of spinal fusions are mediocre. New epidemiological studies show that "spinal fusion must be accepted as a non proved or experimental method for the treatment of back pain". The surgical literature on spinal fusion published in the last 20 years following the Cochrane's method establish that: 1- this is at least incomplete, not reliable and careless; 2- the instrumentation seems to slightly increase the fusion rate; 3- the instrumentation doesn't improve the clinical results in general, lacking studies in subgroups of patients. We still are needing randomized studies to compare the surgical results with the natural history of the disease, the placebo effect, or the conservative treatment. The European Guidelines for lumbar chronic pain management show a "strong evidence" indicating that complex and demanding spine surgery where different instrumentation is used, is not more effective than a simple, safer and cheaper posterolateral fusion without instrumentation. Recently, the literature published in this field is sending a message to use "minimally invasive techniques", abandon transpedicular fusions and clearly indicating that we must apply the knowledge accumulated at least along the last 20 years based on the scientific evidence. In conclusion, based in recent information, we must recommend the "abandon of the instrumented pathway" in a great number of present indications for degenerative spine surgery, and look for new strategies in the field of rehabilitation and conservative treatments correctly apply, using before the decompressive and instrumented surgery all the interventional and minimally invasive techniques that are presently offer in the field of modem lumbar chronic pain treatment.

Breast-conservation surgery has been shown to be equivalent to mastectomy in terms of long-term survival for the treatment of breast cancer. Various techniques have been described on how to achieve clear margins and good cosmetic outcomes and therefore expand the indications for breast conservation. A novel incision is detailed to augment the options already available.

No series had been reported focusing on the results of fertility-sparing surgery in stage I mucinous ovarian cancers according to histotype (infiltrative vs. expansile). Investigating such outcomes was the aim of the present study. The present study was a retrospective analysis of patients treated conservatively with preservation of the uterus and contralateral ovary from 1976 to 2016. The pathology of the tumors was reviewed by two expert pathologists according to the 2014 World Health Organization (WHO) classification criteria. Oncologic and fertility results were analyzed. Twenty-one patients fulfilled the inclusion criteria, twelve with expansile and nine with infiltrative cancer. All patients had a unilateral tumor and underwent unilateral salpingo-oophorectomy in one-step ( n  = 6) or two-step ( n  = 15) surgeries. All but one had complete peritoneal staging surgery based on cytology, omentectomy, and random peritoneal biopsies. Ten had nodal staging surgery. The International Federation of Gynecology and Obstetrics stages were IA ( n  = 9), IC1 ( n  = 6), and IC2 ( n  = 6); the nuclear grades were grade 1 ( n  = 9), grade 2 ( n  = 5), and grade 3 ( n  = 1). Two patients recurred (one expansile and one infiltrative type) 19 and 160 months after surgery, respectively. One stage IA, nuclear grade 2 expansile tumor recurred on the spared ovary; the patient remains alive. The other stage IA infiltrative tumor recurred as peritoneal spread; the patient is alive with disease. Six patients became pregnant; four with expansile tumors and two with infiltrative tumors. The type of mucinous cancer has no impact on the oncologic outcome in this series of patients treated conservatively. Fertility-sparing surgery should be considered for early-stage infiltrative-type tumors. According to the most recently updated World Health Organization classification guidelines, mucinous cancers should be classified as either expansile or infiltrative. The infiltrative type has a poorer prognosis, but there are no data about the safety of fertility-sparing surgery (FSS) in this context. A collection of 21 cases reviewed by two expert pathologists this study is the first devoted to the conservative treatment of mucinous tumors according to both subtypes. The key result was that the type of mucinous cancer has no impact on the oncologic outcome; thus, FSS may be considered in both subtypes. © AlphaMed Press 2017.

Influence of previous breast surgery in sentinel lymph node biopsy in patients with breast cancer.

López-Prior, V; Díaz-Expósito, R; Casáns Tormo, I

The aim of this study was to review the feasibility of selective sentinel lymph node biopsy in patients with previous surgery for breast cancer, as well as to examine the factors that may interfere with sentinel node detection. A retrospective review was performed on 91 patients with breast cancer and previous breast surgery, and who underwent sentinel lymph node biopsy. Patients were divided into two groups according to their previous treatment: aesthetic breast surgery in 30 patients (group I) and breast-conserving surgery in 61 (group II). Lymphoscintigraphy was performed after an intra-tumour injection in 21 cases and a peri-areolar injection in 70 cases. An analysis was made of lymphatic drainage patterns and overall sentinel node detection according to clinical, pathological and surgical variables. The overall detection of the sentinel lymph node in the lymphoscintigraphy was 92.3%, with 7.7% of extra-axillary drainages. The identification rate was similar after aesthetic breast surgery (93.3%) and breast-conserving surgery (91.8%). Sentinel lymph nodes were found in the contralateral axilla in two patients (2.2%), and they were included in the histopathology study. The non-identification rate in the lymphoscintigraphy was 7.7%. There was a significantly higher non-detection rate in the highest histological grade tumours (28.6% grade III, 4.5% grade I and 3.6% grade II). Sentinel lymph node biopsy in patients with previous breast surgery is feasible and deserves further studies to assess the influence of different aspects in sentinel node detection in this clinical scenario. A high histological grade was significantly associated with a lower detection. Copyright © 2017 Elsevier España, S.L.U. y SEMNIM. All rights reserved.

As Wireless Sensor Networks are being adopted by industry and agriculture for large-scale and unattended deployments, the need for reliable and energy-conservative protocols become critical. Physical and Link layer efforts for energy conservation are not mostly considered by routing protocols that put their efforts on maintaining reliability and throughput. Gradient-based routing protocols route data through most reliable links aiming to ensure 99% packet delivery. However, they suffer from the so-called "hot spot" problem. Most reliable routes waste their energy fast, thus partitioning the network and reducing the area monitored. To cope with this "hot spot" problem we propose ZERO a combined approach at Network and Link layers to increase network lifespan while conserving reliability levels by means of probabilistic load balancing techniques.

Hysteroscopic surgery for conservative management in endometrial cancer: a review of the literature

2015-01-01

Endometrial cancer is the most common gynaecologic malignancy, usually diagnosed in postmenopausal women. However, an incidence rate of 2–14% of cases consisting of women under the age of 45 years old has been reported. Multiple reports have described the conservative treatment of this tumour in selected patients with the objective of preserving fertility. In this article, we review the literature to evaluate the results of conservative treatment of endometrial cancer with hysteroscopic resection. PMID:25729418

The multicenter randomized controlled COBALT trial demonstrated that ultrasound-guided breast-conserving surgery (USS) results in a significant reduction of margin involvement (3.1% vs. 13%) and excision volumes compared to palpation-guided surgery (PGS). The aim of the present study was to determine long term oncological and patient-reported outcomes including quality of life (QoL), together with their progress over time. 134 patients with T1-T2 breast cancer were randomized to USS (N = 65) or PGS (N = 69). Cosmetic outcomes were assessed with the Breast Cancer Conservative Treatment cosmetic results (BCCT.core) software, panel-evaluation and patient self-evaluation on a 4-point Likert-scale. QoL was measured using the EORTC QLQ-C30/-BR23 questionnaire. No locoregional recurrences were reported after mean follow-up of 41 months. Seven patients (5%) developed distant metastatic disease (USS 6.3%, PGS 4.4%, p = 0.466), of whom six died of disease (95.5% overall survival). USS achieved better cosmetic outcomes compared to PGS, with poor outcomes of 11% and 21% respectively, a result mainly attributable to mastectomies due to involved margins following PGS. There was no difference after 1 and 3 years in cosmetic outcome. Dissatisfied patients included those with larger excision volumes, additional local therapies and worse QoL. Patients with poor/fair cosmetic outcomes scored significantly lower on aspects of QoL, including breast-symptoms, body image and sexual enjoyment. By significantly reducing positive margin status and lowering resection volumes, USS improves the rate of good cosmetic outcomes and increases patient-satisfaction. Considering the large impact of cosmetic outcome on QoL, USS has great potential to improve QoL following breast-conserving therapy.

Chargari, Cyrus, E-mail: cyrus.chargari@gustaveroussy.fr; Institut de Recherche Biomédicale des Armées, Bretigny-sur-Orge; French Military Health Service Academy, Ecole du Val-de-Grâce, Paris

Purpose: To report the results of a conservative strategy based on partial surgery combined with brachytherapy in a prospective cohort of children with bladder–prostate rhabdomyosarcoma (BP RMS). Methods and Materials: We prospectively documented the outcome of children treated in our department between 1991 and 2015 for BP RMS and undergoing a multimodal approach combining conservative surgery (partial cystectomy and/or partial prostatectomy) and perioperative interstitial low-dose-rate or pulse-dose-rate brachytherapy. Before brachytherapy, children had received chemotherapy with modalities depending on their risk group of treatment. Results: A total of 100 patients were identified, with a median age of 28 months (range, 5.6 months-14more » years). According to the Intergroup Rhabdomyosarcoma Study (IRS) group, 84 were IRS-III, and 12 were IRS-IV tumors. Four patients were treated at relapse. The median number of chemotherapy cycles before local therapy was 6 (range, 4-13). After surgery, 63 patients had a macroscopic tumor residuum. Five patients underwent a brachytherapy boost before pelvic external beam radiation therapy because of nodal involvement, and 95 had exclusive brachytherapy. Median follow-up was 64 months (range, 6 months-24.5 years). Five-year disease-free and overall survival rates were 84% (95% confidence interval 80%-88%) and 91% (95% confidence interval 87%-95%), respectively. At last follow-up most survivors presented with only mild to moderate genitourinary sequelae and a normal diurnal urinary continence. Five patients required a secondary total cystectomy: 3 for a nonfunctional bladder and 2 for relapse. Conclusion: Brachytherapy is effective as part of a conservative strategy for BP RMS, with a relatively low delayed toxicity as compared with previously published studies using external beam radiation therapy. Longer follow-up is required to ensure that the functional results are maintained over time.« less

Ovarian masses requiring surgical intervention are uncommon in the pediatric population. Our aim is to report results of a multicentric Tunisian study concerning the clinical practice and the management of pediatric ovarian masses and to identify the factors that are associated with ovarian preservation. Between January 2000 and December 2015, 98 pediatric patients (<14 years) were surgically treated for ovarian masses at the five pediatric surgery departments in Tunisia. Ninety-eight patients were included in this study. The mean age of the patients at time of surgery was 8.46 ± 4.87 years. Sixty-three ovarian masses (64.3%) were non-neoplastic lesions, 24 (24.5%) were benign tumors, and 11 (11.2%) were malignant neoplasms. Conservative surgery (ovarian-preserving surgery) was successfully performed in 72.4% of the benign lesions, whereas only three patients (27.3%) with malignant tumors underwent ovary-sparing tumor resection (p < .001). The mean diameter of the tumors in the patients who underwent oophorectomy was significantly larger than that in the patients who underwent conservative surgery (7.8 ± 3.9 cm vs. 5.7 ± 2.9 cm, respectively, p = .001). In our study, the risk factors for oophorectomy were a malignant pathology and large tumor size. In accordance with the Gynecologic Cancer Intergroup consensus, we recommend that surgical management of ovarian masses in children should be based on ovarian-preserving surgery.

Because of its high requirements on surgical experience and the need of complete understanding of the anatomy, oral surgery and especially implantology belong to the most demanding procedures in dentistry. Therefore, hands-on courses for oral surgery and implantology are considered a prerequisite to prepare for clinical practice. To achieve teaching conditions as realistic as possible, we used a novel human cadaver embalming method enabling tissue dissection comparable with the living body. Thirty cadavers which were offered by the Institute of Anatomy for the purpose of running oral surgery and implantology courses were embalmed in the technique described by Thiel. On each cadaver, dissection of soft and hard tissue and implantological procedures were performed according to a structured protocol by each course participant. The conservation of fine anatomical structures and the suitability of the embalmed tissue for dissecting, drilling, and suturing were observed and photographically documented. By means of the Thiel embalming technique, oral surgery and implantological procedures could be performed under realistic conditions similar to the living body. Due to the conservation procedure, preparations could be carried out without any time limit, always maintaining the same high quality of the tissue. The maxillary sinus membrane, mucosa, bone, and nerves could be exposed and allowed dissecting, drilling, and suturing even after weeks like fresh specimens. The Thiel embalming method is a unique technique which is ideally suited to practice and teach oral surgery and implantology on human material. © 2009 Wiley Periodicals, Inc.

Conservative treatment of postoperative chylothorax: a case report.

PubMed

Wagh, Sachinkumar; Deshmukh, Sanjay; Ankolikar, Shrikant

2018-02-06

Chylothorax is a well-documented complication of thoracic trauma and is associated with high rates of morbidity and mortality. Treatment for chylothorax includes conservative measures (total parenteral nutrition, pleural drainage, and pleurodesis) and surgery (thoracic duct ligation). We present the case of a 65-year-old man who developed chylothorax after an elective surgical procedure. In this report conservative treatment aims to reduce chyle flow, to drain the pleural cavity in an effective manner, and to prevent chronic sequelae. Optimal conservative treatment, started immediately upon diagnosis, effectively reduces the need for reoperation and long-term hospitalization, and it might prevent further sequelae of chylothorax. The chylothorax was successfully treated conservatively, which may reduce the need for reoperation.

Surgical excision of tumor is a critical factor in the management of breast cancer. The most common surgical procedure is breast-conserving surgery. The surgeon's goal is to remove the tumor and a rim of healthy tissue surrounding the tumor: the surgical margin. A major issue in breast-conserving surgery is the absence of a reliable tool to guide the surgeon in intraoperatively assessing the margin. A number of techniques have been proposed; however, the re-excision rate remains high and has been reported to be in the range 30-60%. New tools are needed to address this issue. Optical coherence elastography (OCE) shows promise as a tool for intraoperative tumor margin assessment in breast-conserving surgery. Further advances towards clinical translation are limited by long scan times and small fields of view. In particular, scanning over sufficient areas to assess the entire margin in an intraoperative timeframe has not been shown to be feasible. Here, we present a protocol allowing ~75% of the surgical margins to be assessed within 30 minutes. To achieve this, we have incorporated a 65 mm-diameter (internal), wide-aperture annular piezoelectric transducer, allowing the entire surface of the excised tumor mass to be automatically imaged in an OCT mosaic comprised of 10 × 10 mm tiles. As OCT is effective in identifying adipose tissue, our protocol uses the wide-field OCT to selectively guide subsequent local OCE scanning to regions of solid tissue which often present low contrast in OCT images. We present promising examples from freshly excised human breast tissue.

The increased complexity of the decisional process in breast cancer surgery is well documented. With this study we aimed to create a software tool able to assist patients and surgeons in taking proper decisions. We hypothesized that the endpoints of breast cancer surgery could be addressed combining a set of decisional drivers. We created a decision support system software tool (DSS) and an interactive decision tree. A formal analysis estimated the information gain derived from each feature in the process. We tested the DSS on 52 patients and we analyzed the concordance of decisions obtained by different users and between the DSS suggestions and the actual surgery. We also tested the ability of the system to prevent post breast conservation deformities. The information gain revealed that patients preferences are the root of our decision tree. An observed concordance respectively of 0.98 and 0.88 was reported when the DSS was used twice by an expert operator or by a newly trained operator vs. an expert one. The observed concordance between the DSS suggestion and the actual decision was 0.69. A significantly higher incidence of post breast conservation defects was reported among patients who did not follow the DSS decision (Type III of Fitoussi, N = 4; 33.3%, p = 0.004). The DSS decisions can be reproduced by operators with different experience. The concordance between suggestions and actual decision is quite low, however the DSS is able to prevent post- breast conservation deformities. Copyright © 2016 Elsevier Ltd. All rights reserved.

We examine issues to consider when reframing conservation science and practice in the context of global change. New framings of the links between ecosystems and society are emerging that are changing peoples' values and expectations of nature, resulting in plural perspectives on conservation. Reframing conservation for global change can thus be regarded as a stage in the evolving relationship between people and nature rather than some recent trend. New models of how conservation links with transformative adaptation include how decision contexts for conservation can be reframed and integrated with an adaptation pathways approach to create new options for global-change-ready conservation. New relationships for conservation science and governance include coproduction of knowledge that supports social learning. New processes for implementing adaptation for conservation outcomes include deliberate practices used to develop new strategies, shift world views, work with conflict, address power and intergenerational equity in decisions, and build consciousness and creativity that empower agents to act. We argue that reframing conservation for global change requires scientists and practitioners to implement approaches unconstrained by discipline and sectoral boundaries, geopolitical polarities, or technical problematization. We consider a stronger focus on inclusive creation of knowledge and the interaction of this knowledge with societal values and rules is likely to result in conservation science and practice that meets the challenges of a postnormal world. © 2017 The Authors.

2016-01-01

Objective Chronic subdural hematoma (cSDH) is common condition in neurosurgical field. It is difficult to select the treatment modality between the surgical method and the conservative method when patients have no or mild symptoms. The purpose of this study is to provide a suggestion that the patients could be cured with conservative treatment modality. Methods We enrolled 16 patients who had received conservative treatment for cSDH without special medications which could affect hematoma resolution such as mannitol, steroids, tranexamic acid and angiotensin converting enzyme inhibitors. The patients were classified according to the Markwalder's Grading Scale. Results Among these 16 patients, 13 (81.3%) patients showed spontaneously resolved cSDH and 3 (18.7%) patients received surgery due to symptom aggravation and growing hematoma. They were categorized into two groups based on whether they were cured with conservative treatment or not. The first group was the spontaneous resolution group. The second group was the progression-surgery group. The mean hematoma volume in the spontaneous resolution group was 43.1 mL. The mean degree of midline shift in the spontaneous resolution group was 5.3 mm. The mean hematoma volume in the progression-surgery group was 62.0 mL. The mean degree of midline shift in the second group was 6 mm. Conclusion We suggest that the treatment modality should be determined according to the patient's symptoms and clinical condition and close observation could be performed in patients who do not have any symptoms or in patients who have mild to moderate headache without neurological deterioration.

The optimal treatment of ductal carcinoma in situ (DCIS) of the breast has not yet been established. The effectiveness of adjuvant postoperative radiotherapy after conservative surgery is debated. Few data are available in Italy on the combined treatment. A collaborative multi-institutional study on this issue in 10 radiation oncology departments of the north-east of Italy was conducted. One hundred and thirty nine women with DCIS of the breast were treated between 1980 and 1990. Age ranged between 28 and 88 years (median 50 years). Surgical procedures were: quadrantectomy in 108, lumpectomy in 22 and wide excision in 9 cases. The axilla was surgically staged in 97 cases: all the patients were node-negative. Radiation therapy was delivered with 60Co units (78%) or 6 MV linear accelerators (22%) for a median total dose to the entire breast of 50 Gy (mean 49.48 Gy; range 45-60 Gy). The tumour bed was boosted in 109 cases (78%) at a dose of 4-30 Gy (median 10 Gy) for a minimum tumour dose of 58 Gy. Median follow-up was 81 months. Thirteen local recurrences were recorded, 7 intraductal and 6 invasive. All recurrent patients had a salvage mastectomy and are alive and free of disease. Actuarial overall, cause-specific and recurrence-free survival at 10 years are of 93%, 100% and 86%, respectively. The results of this retrospective multicentric study substantiate the favourable data reported in the literature and confirm the efficacy of the breast-conserving treatment of DCIS employing conservative surgery and adjuvant radiation therapy.

Surgery is still the standard treatment for desmoid-type fibromatosis (DF). Recently, the Institut Gustave Roussy (IGR), Villejuif, France, reported a series of patients treated with a front-line conservative approach (no surgery and no radiotherapy). The disease remained stable in more than half of patients. This study was designed to evaluate this approach on the natural history of the disease in a larger series of patients. A total of 142 patients presenting to the IGR or Istituto Nazionale Tumori (INT), Milan, Italy, were initially treated using a front-line deliberately conservative policy. Their progression-free survival (PFS) was observed and a multivariate analysis was performed for major clinical variables. Seventy-four patients presented with primary tumor, 68 with recurrence. Eighty-three patients received a "wait & see" policy (W&S), whereas 59 were initially offered medical therapy (MT), mainly hormonal therapy and chemotherapy. A family history of sporadic colorectal cancer was present in 8% of patients. The 5-year PFS was 49.9% for the W&S group and 58.6% for the medically treated patients (P = 0.3196). Similar results emerged for primary and recurrent DF. Multivariate analysis identified no clinical variables as independent predictors of PFS. In the event of progression, all patients were subsequently managed safely. A conservative policy could be a safe approach to primary and recurrent DF, which could avoid unnecessary morbidity from surgery and/or radiation therapy. Half of patients had medium-term stable disease after W&S or MT. A multidisciplinary, stepwise approach should be prospectively tested in DF.

Determining environmental causes of biological effects: the need for a mechanistic physiological dimension in conservation biology.

PubMed

Seebacher, Frank; Franklin, Craig E

2012-06-19

The emerging field of Conservation Physiology links environmental change and ecological success by the application of physiological theory, approaches and tools to elucidate and address conservation problems. Human activity has changed the natural environment to a point where the viability of many ecosystems is now under threat. There are already many descriptions of how changes in biological patterns are correlated with environmental changes. The next important step is to determine the causative relationship between environmental variability and biological systems. Physiology provides the mechanistic link between environmental change and ecological patterns. Physiological research, therefore, should be integrated into conservation to predict the biological consequences of human activity, and to identify those species or populations that are most vulnerable.

Conservative treatment (intensive care, a combination of antimicrobial agents, and nutritional support, with or without drainage of the infected fluid) has recently been shown to be effective for patients with infected pancreatic necrosis (IPN), but the data from individual studies are not robust enough to recommend it as the standard of care. We performed a systematic review and meta-analysis of studies related to primary conservative management for IPN. We performed a literature search of MEDLINE/PubMed from January 1990 to March 2012 for studies of a priori protocols for primary conservative treatment, without necrosectomy, for consecutive patients with IPN. We analyzed data from 8 studies, comprising 324 patients with IPN who received primary conservative management. We then analyzed an additional 4 studies (comprising 157 patients) that reported the efficacy of percutaneous drainage in nonconsecutive patients with IPN. Outcome measures were the success of conservative management strategy, need for necrosectomy, and mortality. There was significant heterogeneity in results among the studies. Based on a random effects model, conservative management was successful for 64% of patients (95% confidence interval [CI], 51%-78%); mortality was 12% (95% CI, 6%-18%), and 26% of patients required necrosectomy or additional surgery for complications (95% CI, 15%-37%). A separate analysis of 4 studies that reported outcomes of nonconsecutive patients with IPN following percutaneous drainage had comparable results; 50% had successful outcomes (95% CI, 43%-58%), mortality was 18% (95% CI, 6%-30%), and 38% of patients required surgery (95% CI, 20%-56%). Conservative management without necrosectomy is a successful approach for 64% of patients with IPN. This approach has low mortality and prevents surgical necrosectomy. Copyright © 2013 AGA Institute.

Early surgical management is the standard of care for penile fracture. Conservative treatment is an option with recent reports revealing lower success rates. We reviewed the data and long-term outcomes of patients with penile injury submitted to surgical or conservative treatment. Between January 2004 and February 2012, 42 patients with penile blunt trauma on an erect penis were admitted to our center. We analyzed the following variables: age, etiology, symptoms and signs, diagnostic tests, treatment used, complications and erectile function during the follow-up. One patient was excluded due to missing information. Thirty-five patients underwent surgical repair and 6 patients were submitted to conservative management. Mean follow-up was 19.2 months (range, 7 days to 72 months). The mean elapsed time from trauma to surgery was 21.3±12.5 hours. Trauma during sexual relationship was the main cause (80.9%) of penile fracture. Urethral injury was present in five patients submitted to surgery. Dorsal vein injury occurred in three patients with false penile fracture and concomitant spongious corpus lesion was present in three patients. During follow-up, 31 cases (88.6%) of the surgical group and four cases (66.7%) of the conservative group reported sufficient erections for intercourse, with no voiding dysfunction and no penile curvature. However, the remaining two patients (33.3%) from the conservative group developed erectile dysfunction and three patients (50%) developed penile deviation. Surgical approach provides excellent functional outcomes and lower complications. Early surgical management of penile fracture provides superior results and conservative approach should be avoided.

Radiation therapy to the breast following breast conservation surgery has been the standard of care since randomized trials demonstrated equivalent survival compared to mastectomy and improved local control and survival compared to breast conservation surgery alone. Recent controversies regarding adjuvant radiation therapy have included the potential role of additional radiation to the regional lymph nodes. This review summarizes the evolution of regional nodal management focusing on 2 topics: first, the changing paradigm with regard to surgical evaluation of the axilla; second, the role for regional lymph node irradiation and optimal design of treatment fields. Contemporary data reaffirm prior studies showingmore » that complete axillary dissection may not provide additional benefit relative to sentinel lymph node biopsy in select patient populations. Preliminary data also suggest that directed nodal radiation therapy to the supraclavicular and internal mammary lymph nodes may prove beneficial; publication of several studies are awaited to confirm these results and to help define subgroups with the greatest likelihood of benefit.« less

Applicants for craniofacial surgery fellowships utilize Internet-based resources like the San Francisco (SF) Match to manage applications. The purpose of this study was to evaluate the accessibility and content of craniofacial surgery fellowship websites (CSFWs). A list of available craniofacial surgery fellowships was compiled from directories of the American Society of Craniofacial Surgery (ACSFS) and SF Match. Accessibility of CSFWs was assessed via links from these directories and a Google search. Craniofacial surgery fellowship websites were evaluated on education and recruitment content and compared via program characteristics. Twenty-four of the 28 US-based craniofacial surgery fellowship programs had a CSFW (86%). The ACSFS and SF Match databases had limited CSFW accessibility, but a Google search revealed most CSFWs had the top search result (76%). In total, CSFWs provided an average of 39% of education and recruitment variables. While most programs provided fellowship program descriptions (96%), application links (96%), and faculty listings (83%), relatively few provided rotation schedules (13%), fellow selection process information (13%), or interview dates (8%). CSFW content did not vary by program location, faculty size, accreditation status, or institutional affiliations (P > 0.05). Craniofacial surgery fellowships often lack readily accessible websites from national program lists and have limited information for interested applicants. The consistent lack of online information across programs suggests future opportunities exist to improve these educational resources.

At present, it is unclear which is the best management for Achilles tendon rupture. We assess the clinical, functional and imaging outcomes of active patients undergoing 3 different types of management for acute subcutaneous rupture of the Achilles tendon, including conservative cast immobilization, traditional open surgery and percutaneous repair. 26 active patients were managed for a rupture of the Achilles Tendon from January 2007 to March 2008. Anthropometric measurements, Functional assessment, Isometric strength, Ultrasonographic assessment, Patient satisfaction, Working life, Physical activity, Functional score and Complications were recorded retrospectively. All 23 (21 men, 2 women) patients were reviewed at a minimum follow-up of 24 months (average 25.7, range 24 to 32 months, SD: 6.3) from the index injury. Thermann scores and patient satisfaction were significantly higher following surgery than conservative management with no significance between open and minimally invasive operated patients. Sensitive disturbances occur in up to 12% of open repairs and 1.8% of patients managed nonsurgically. Clinical and functional outcomes following surgical repair, percutaneous and open, of the Achilles tendon are significantly improved than following conservative management. Level III.

Surgery is an effective treatment in severe cases of supraglottic exercise-induced laryngeal obstruction (E-ILO). Conservatively treated subjects and subjects tested negative for E-ILO, who still experience breathing problems 1-3 years after diagnosis, tend to adjust their physical activity to a greater extent than surgically treated subjects. To investigate how symptoms and level of physical activity change over time in patients with E-ILO who have undergone surgery, patients with E-ILO treated conservatively and patients who tested negative for laryngeal obstruction at continuous laryngoscopy exercise-test (CLE-test). Patients referred for exercise-induced breathing difficulties answered questionnaires at diagnostic CLE-test and at follow-up. Questions regarded exercise-induced breathing problems, current physical activity level, and medical history of asthma and perennial allergy. Out of 84 invited subjects, 59 (70%) answered both questionnaires. Surgically treated subjects had less breathing problems at follow-up compared with conservatively treated subjects and subjects who tested negative (p < 0.001). None of the surgically treated subjects were less physically active or had changed sport due to exercise-induced dyspnoea, whereas 41.7% of the conservatively treated subjects had made such adjustments (p < 0.001).

In the sub-Saharan African setting, laparotomy for salpingectomy is the common method of treatment for ectopic pregnancy (EP). The objective of this retrospective study was to find out how common EP is treated conservatively in the Yaounde Gynaeco-Obstetric and Paediatric Hospital, Cameroon. Of the 281 patient files analysed, 126 patients (44.8%) were treated conservatively and successfully for EP. Of these, 86 (68.2%) had received conservative surgical treatment while 40 (31.8%) had non-surgical treatment. Salpingostomy was the conservative surgery for 79.1% of the cases. According to the publications available for the sub-Saharan setting, the rate of conservative management of EP at the Yaounde Gynaeco-Obstetric and Paediatric Hospital, Cameroon is high. We recommend that this rate should be improved so that, eventually, the conservative treatment methods of EP become routine.

Shoulder problems are common in patients with a cervical herniated intervertebral disc (HIVD). This study aimed to explore the incidence and risk of shoulder capsulitis/tendonitis following cervical HIVD surgery. We used data from the Taiwan "Longitudinal Health Insurance Database". We identified all patients who were hospitalized with a diagnosis of displacement of a cervical HIVD and who underwent cervical surgery (n = 1625). We selected 8125 patients who received cervical HIVD conservative therapy only as the comparison group matched with study patients. We individually tracked these sampled patients for 6 months to identify all patients who received a diagnosis of shoulder tendonitis/capsulitis. We found that incidence rates of shoulder tendonitis/capsulitis during the 6-month follow-up period were 3.69 (95% CI: 2.49~5.27) per 100 person-years for the study group and 2.33 (95% CI: 1.89~2.86) per 100 person-years for the comparison group. Cox proportional hazard regressions showed that the adjusted hazard ratio for shoulder tendonitis/capsulitis among patients who underwent cervical disc surgery was 1.66 (95% CI = 1.09~2.53) when compared to comparison group. We concluded that patients who underwent surgery for a cervical HIVD had a significantly higher risk of developing shoulder capsulitis/tendonitis in 6 months follow-up compared to patients who received cervical HIVD conservative therapy only.

Sabah, formerly known as North Borneo, is part of East Malaysia. 52.2 percent of patients with breast cancer in Sabah presented at advanced stages and up to 20.4 percent of patients defaulted proper treatment, opting for traditional therapy. We performed a two-year prospective study looking at the treatment trends of breast cancer in Sabah. Our subjects were all newly-diagnosed breast cancer cases seen at the hospital in 2005 and 2006. Type of surgery, chemotherapy, radiotherapy, hormonal therapy and surgical complication for each patient were studied. Out of 186 newly-diagnosed cases, 152 (81.7 percent) had surgery, 126 (67.7 percent) had chemotherapy, 118 (63.4 percent) had radiotherapy and 92 (49.5 percent) had hormonal therapy. 18.3 percent did not have surgery either due to refusal of treatment or advanced disease. They were more likely to be non-Chinese (91.1 percent, p-value is 0.02). Only 15.8 percent had breast-conserving surgery. The most frequent surgical complication was seroma formation (15.0 percent) . The commonest chemotherapy regime and hormonal therapy were anthracycline-based regime (88.1 percent) and tamoxifen (95.8 percent), respectively. The proportion of breast-conserving surgery and usage of modern adjuvant therapies are low in Sabah. This can be attributed to lack of breast cancer awareness leading to late presentation and refusal of treatment, coupled with insufficient health service funding.

The Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database (ACSD) has been successfully linked to the Centers for Medicare and Medicaid (CMS) Medicare database, thereby facilitating comparative effectiveness research and providing information about long-term follow-up and cost. The present study uses this link to determine contemporary completeness, penetration, and representativeness of the STS ACSD. Using variables common to both STS and CMS databases, STS operations were linked to CMS data for all CMS coronary artery bypass graft (CABG) surgery hospitalizations discharged between 2000 and 2012, inclusive. For each CMS CABG hospitalization, it was determined whether a matching STS record existed. Center-level penetration (number of CMS sites with at least one matched STS participant divided by the total number of CMS CABG sites) increased from 45% in 2000 to 90% in 2012. In 2012, 973 of 1,081 CMS CABG sites (90%) were linked to an STS site. Patient-level penetration (number of CMS CABG hospitalizations done at STS sites divided by the total number of CMS CABG hospitalizations) increased from 51% in 2000 to 94% in 2012. In 2012, 71,634 of 76,072 CMS CABG hospitalizations (94%) occurred at an STS site. Completeness of case inclusion at STS sites (number of CMS CABG cases at STS sites linked to STS records divided by the total number of CMS CABG cases at STS sites) increased from 88% in 2000 to 98% in 2012. In 2012, 69,213 of 70,932 CMS CABG hospitalizations at STS sites (98%) were linked to an STS record. Linkage of STS and CMS databases demonstrates high and increasing penetration and completeness of the STS database. Linking STS and CMS data facilitates studying long-term outcomes and costs of cardiothoracic surgery. Copyright © 2016 The Society of Thoracic Surgeons. Published by Elsevier Inc.

2015-01-01

Introduction The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides access to breast and cervical cancer screening for low-income, uninsured, and underinsured women in all states and US territories. In Idaho, a rural state with very low breast and cervical cancer screening rates, this program is called Women’s Health Check (WHC). The program has been operating continuously since 1997 and served 4,719 enrollees in 2013. The objective of this study was to assess whether disparities existed in cause-specific survival (a net survival measure representing survival of a specified cause of death in the absence of other causes of death) between women screened by WHC and outside WHC and to determine how type of surgery or survival varies with stage at diagnosis. Methods WHC data were linked to Idaho’s central cancer registry to compare stage distribution, type of surgery, and cause-specific survival between women with WHC-linked breast cancer and a comparison group of women whose records did not link to the WHC database (nonlinked breast cancer). Results WHC-linked breast cancer was significantly more likely to be diagnosed at a later stage of disease than nonlinked breast cancer. Because of differences in stage distribution between WHC-linked and nonlinked breast cancers, overall age-standardized, cause-specific breast cancer survival proportions diverged over time, with a 5.1 percentage-point deficit in survival among WHC-linked cases at 5 years of follow-up (83.9% vs 89.0%). Differences in type of surgery and cause-specific survival were attenuated when controlling for stage. Conclusion This study suggests that disparities may exist for Idaho WHC enrollees in the timely diagnosis of breast cancer. To our knowledge, this is the first study to publish comparisons of cause-specific breast cancer survival between NBCCEDP-linked and nonlinked cases. PMID:25789497

The care of patients with breast cancer is extremely complex and requires interdisciplinary care in certified facilities. These specialized facilities provide numerous services without being correspondingly remunerated. The question whether breast cancer surgery should be performed in an outpatient setting to reduce costs is increasingly being debated. This study compares inpatient surgical treatment with a model of the same surgery performed on an outpatient basis to examine the potential financial impact. A theoretical model was developed and the DRG fees for surgical interventions to treat primary breast cancer were calculated. A theoretical 1-day DRG was then calculated to permit comparisons with outpatient procedures. The costs of outpatient surgery were calculated based on the remuneration rates of the AOP (Outpatient Surgery) Contract and the EBM (Uniform Assessment Scale) and compared to the costs of the 1-day DRG. The DRG fee for both breast-conserving surgery and mastectomy is higher than the fee paid in the context of the EBM system, although the same procedures were carried out in both systems. If a hospital were to carry out breast-conserving surgery as an outpatient procedure, the fee would be € 1313.81; depending on the type of surgery, the hospital would therefore only receive between 39.20% and 52.82% of the DRG fee. This was the case even for a 1-day treatment. Compared to the real DRG fees the difference would be even more striking. Carrying out breast cancer surgery as an outpatient procedure would result in a significant shortfall of revenues. Additional services from certified centers, such as the interdisciplinary planning of treatment, psycho-oncological and social-medical care with the involvement of relatives, detailed documentation, etc., which are currently provided without surcharge or adequate remuneration, could no longer be maintained. The quality of processes and excellent results which have been achieved and ultimately the care given by certified facilities would be significantly at risk.

Appearance of the male genitalia is linked with self-esteem and sexual identity. Aesthetic surgery of the male genitalia serves to correct perceived deficiencies as well as physical deformities, which may cause psychological distress. Attention to patient motivation for surgery and to surgical technique is key to achieving optimal results. In this review, the authors describe aesthetic surgical techniques for treatment of penile and scrotal deficiencies. They also discuss techniques for revision in patients with previous surgery.

The threatened stomach: management of the acute gastric volvulus.

Acute presentation of gastric volvulus is a rare condition with a high mortality for acute ischaemia. This study was undertaken to investigate the acute management, diagnosis, and long-term outcomes of patients presenting with acute gastric volvulus. Cases were reviewed retrospectively from 2004 to 2014. Patients presenting as an emergency admission with acute gastric volvulus were included. Thirty-six patients were included, five of whom had previous surgery. The mean age was 71 years old. All patients presented with vomiting and chest/epigastric pain. CT was diagnostic in all 26 patients. Barium swallow was diagnostic in two/four patients. OGD was diagnostic in 9 of 20 patients. All patients had an NG tube placed, and eight patients were treated conservatively and made a full recovery. Twenty-nine patients proceeded to surgery. Nine had a laparoscopic repair with two open conversions. Four patients had gastric necrosis, and all had open surgery with resection. Three patients had a mediastinal perforation, and one patient required an additional thoracotomy. All patients with viable stomach had a hiatal repair (where appropriate), 11 had a gastropexy, and 11 had a fundoplication. Mortality for gastric necrosis/perforation was 30 %. Mean postoperative stay was 4 days for laparoscopic repair and 8 days for uncomplicated open surgery. Nine of twenty-nine had transient dysphagia postoperatively. Three of eight patients treated conservatively had an elective procedure subsequently. Acute paraoesophageal hiatus hernia requires early resuscitation and diagnosis. CT should be favoured in assessment, and an NG tube placed promptly. A conservative management may be considered safely in stable patients. Surgical management should be prompt for unstable patients. Gastric ischaemia or perforation has a mortality of 30 %. Laparoscopic repair has a shorter postoperative stay, but has a higher recurrence rate. Surgery for patients without gastric ischaemia has good long-term outcomes with minimal morbidity.

Patients with ipsilateral breast tumor recurrence or new ipsilateral primary tumor after previous breast conservative surgery with negative sentinel lymph node biopsy need a new axillary staging procedure. However, the best surgical option, i.e. repeat sentinel lymph node biopsy or axillary lymph node dissection, is still debated. Purpose of the study is to assess the performance of repeat sentinel lymph node biopsy. In a multicenter study, lymph node biopsy completed by back-up axillary lymph node dissection was undertaken for ipsilateral breast tumor recurrence or new ipsilateral primary tumor. Tracer uptake was used to identify and isolate the sentinel lymph node during surgery, and it was classified after staining with hematoxylin and eosin and monoclonal anti-cytokeratin antibodies. Aside from negative predictive value, overall accuracy and false-negative rate of repeat sentinel lymph node biopsy were assessed. A multicenter, prospective study was conducted performing 30 repeat sentinel lymph node biopsy completed by back-up axillary lymph node dissection for ipsilateral breast tumor recurrence or new ipsilateral primary tumor in patients formerly treated with previous breast conservative surgery and negative sentinel lymph node biopsy. Negative predictive value, overall accuracy and false-negative rate of repeat sentinel lymph node biopsy were assessed. Sentinel lymph nodes were mapped in 27 patients out of 30 (90%). Aberrant drainage pathways were observed in one patient (3.7%). Tracer uptake was sufficient to identify and isolate the sentinel lymph node during surgery in 23 cases (76.6%); the patients in whom lymphoscintigraphy failed or no sentinel lymph nodes could be isolated underwent axillary lymph node dissection. The negative predictive value was 95.2%, the accuracy was 95.6% and the false-negative rate was 33%. Repeat sentinel lymph node biopsy is feasible and accurate, with a high negative predictive value. Patients with ipsilateral breast tumor recurrence or new ipsilateral primary tumor after previous breast conservative surgery and negative sentinel lymph node biopsy can be treated with repeat sentinel lymph node biopsy for the axillary staging and can be spared axillary dissection in case of absence of metastases. However, repeat sentinel lymph node biopsy may prove technically impracticable in about one quarter of cases and thus axillary lymph node dissection remains the only viable option in such instance.

Temporo-Mandibular Joints (TMJ) and orthognathic surgery are closely linked. In the past, some authors have even described (with mixed results) the correction of some dysmorphosis through direct procedures on the TMJs. Nowadays, performing orthognathic surgery involves the TMJ in three different occasions: (1) TMJ disorders potentially responsible for dento-maxillary dysmorphosis, (2) effects of orthognathic surgery on TMJs, and (3) condylar positioning methods in orthognathic surgery. These three chapters are developed in order to focus on the close relationships between TMJ and orthognathic surgery. Some perspectives close this article. Copyright © 2016 Elsevier Masson SAS.

These guidelines provide a review of diagnosis, conservative and surgical treatment of haemorrhoids with primary focus on the surgical treatment. In symptomatic hemorrhoids it is recommended, that conservative treatment is used as basic treatment regardless of grading. The vast majority of grade II haemorrhoids are treated conservatively, but surgery may be considered in a few cases with pronounced symptoms. In these cases chirurgia minor, Doppler guided dearterilization procedures or stapled haemorrhoidopexy are recommended. In grade III and IV Doppler guided dearterilization procedures, stapled haemorrhoidopexy (Grade III) or conventional Milligan Morgan haemorrhoidectomy are recommended.

Conservative Management of an Epicardial Collateral Perforation During Retrograde Chronic Total Occlusion Percutaneous Coronary Intervention.

2016-01-01

Coronary artery perforation is a highly feared complication of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) and can lead to pericardial effusion, tamponade, and, rarely, emergent cardiac surgery. Perforation of epicardial collaterals during retrograde CTO-PCI may be particularly challenging to treat, as embolization from both sides of the perforation may be required to control the bleeding. However, conservative measures can occasionally be effective. We present a case of epicardial collateral vessel perforation that was managed conservatively with anticoagulation reversal.

Most extraperitoneal bladder ruptures can be treated conservatively with catheter drainage only. However, in patients with concomitant intrabladder blood clot formation and extraperitoneal bladder rupture, surgery for blood clot evacuation and bladder repair are usually needed due to occlusion of the urinary catheter. In our patient, we used a ureteral catheter to bypass the clots in the bladder to provide adequate urinary drainage. This procedure serves as a valuable tool in the conservative treatment of extraperitoneal bladder injury.

Purpose: Given the paucity of data on racial disparities in ductal carcinoma in situ (DCIS), the data from a multi-institutional cohort of DCIS patients treated with breast-conserving surgery and whole breast radiation therapy (RT) were analyzed to determine whether racial disparities or differences exist. Methods and Materials: A total of 533 white and 76 black DCIS patients from 3 university-based cancer centers were uniformly treated with breast-conserving surgery and RT. All patient data were collected and analyzed as a function of race. Results: The median follow-up was 5.2 years. No significant racial differences were seen in tumor size, age atmore » diagnosis, estrogen receptor status, necrosis, or grade (all P>.05). Of the treatment parameters, the RT dose delivered, boost, positive margin rates, frequency of hormone receptor status assessment, and receipt of hormonal therapy for the 2 cohorts did not significantly differ (all P>.05). The local relapse-free survival was similar at 5 years (96.1% and 98.1%, P=.399) and 10 years (92.8% vs 95.8%, P=.360), with no significant overall survival difference at 10 years (94.0% vs 88.9%, P=.290) between the white and black patients, respectively. On multivariate analysis, race was not an independent predictor of local relapse-free survival or overall survival when accounting for age, grade, and margin status. Conclusion: In our large cohort of DCIS patients uniformly treated at 3 institutions with breast conservation without any apparent differences in treatment delivery parameters, we demonstrated that the clinical and pathologic features and local survival outcomes did not differ as a function of race. Our results suggest that when black patients with DCIS are appropriately selected for breast conservation and receive adjuvant RT without racial disparities in the treatment parameters, differences in the outcomes as a function of race do not exist.« less

Helicity conservation by flow across scales in reconnecting vortex links and knots

PubMed Central

Scheeler, Martin W.; Kleckner, Dustin; Kindlmann, Gordon L.; Irvine, William T. M.

2014-01-01

The conjecture that helicity (or knottedness) is a fundamental conserved quantity has a rich history in fluid mechanics, but the nature of this conservation in the presence of dissipation has proven difficult to resolve. Making use of recent advances, we create vortex knots and links in viscous fluids and simulated superfluids and track their geometry through topology-changing reconnections. We find that the reassociation of vortex lines through a reconnection enables the transfer of helicity from links and knots to helical coils. This process is remarkably efficient, owing to the antiparallel orientation spontaneously adopted by the reconnecting vortices. Using a new method for quantifying the spatial helicity spectrum, we find that the reconnection process can be viewed as transferring helicity between scales, rather than dissipating it. We also infer the presence of geometric deformations that convert helical coils into even smaller scale twist, where it may ultimately be dissipated. Our results suggest that helicity conservation plays an important role in fluids and related fields, even in the presence of dissipation. PMID:25326419

Although direct repair (DR) with screw fixation at the pars defect is a common surgical treatment for lumbar spondylolysis, it is unknown whether DR leads to better outcomes for young patients with spondylolysis than traditional nonsurgical treatment. The purpose of the study was to investigate whether DR was associated with better outcomes for lumbar spondylolysis in young patients than traditional conservative treatment. This is a prospective cohort study. Of 1,784 patients with low back pain in the reference period, 149 young patients with spondylolysis who followed up for at least 1 year were enrolled in the study. The primary outcome was pain intensity at the lower back measured with a Visual Analog Scale. Secondary outcomes included the functional outcome as measured with the Oswestry disability index (ODI) and the 12-item short-form health survey (SF-12) consisting of the physical component summary (PCS) and mental component summary (MCS) scores, the radiologic outcome as measured with lumbar spine radiographs and computed tomography scans, and complications of treatment. This was a prospective comparative study between two groups of patients who were treated with either conservative treatment or surgery for lumbar spondylolysis. Enrolled patients self-selected their own treatment and were allocated to either the traditional care group with conservative treatment (87 patients) or the surgery group (62 patients). All patients were followed up for at least 1 year. Pain intensity at the lower back did not differ significantly between groups at the final follow-up. Likewise, the ODI and SF-12 (PCS and MCS) scores did not differ significantly between groups (p=.13, .71, and .68, respectively). The change in the gap distance of the pars defect at the final follow-up was significantly different between groups (traditional care group: +0.8±0.4 mm; surgery group: -0.7±0.5; p=.01). The union rate at 1 year after surgical treatment was 52% (32/61). The rate of complications was significantly higher in the surgery group (31%) than the traditional care group (20%) (p=.02). Conservative treatment for young patients with spondylolysis may produce similar clinical outcomes and fewer complications over 12-month follow-up than surgical treatment with DR.

to evaluate local and systemic recurrence of breast cancer in patients submitted to autologous fat grafting in the immediate reconstruction after conservative surgery for breast cancer. this is a historical cohort study comparing 167 patients submitted to conservative surgery without reconstruction (conservative surgery group) with 27 patients submitted to conservative treatment with immediate graft reconstruction, following the Coleman's technique (lipofilling group). All patients had invasive carcinoma and were operated by a single surgeon from 2004 to 2011. The postoperative follow-up time was 36 months. the overall incidence of local recurrence was 2.4%. No patient in the lipofilling group had local recurrence during the study period. For systemic recurrence, the rates obtained were 3.7% (one patient) for the fat grafting group and 1.8% (three patients) for the conservative surgery group without reconstruction. there was no significant difference for local or systemic recurrence in the groups studied. Immediate autologous fat grafting appears to be a safe procedure. avaliar recorrência local e sistêmica do câncer de mama em pacientes submetidas ao enxerto autólogo de gordura na reconstrução imediata após cirurgia conservadora para o câncer de mama. estudo de coorte histórica em que foram comparadas 167 pacientes submetidas à cirurgia conservadora sem reconstrução com 27 pacientes submetidas ao tratamento conservador com reconstrução imediata do enxerto, seguindo técnica de Coleman. Todas as pacientes eram portadoras de carcinoma invasor e foram operadas por um único cirurgião, no período de 2004 a 2011. O tempo de acompanhamento pós-operatório foi 36 meses. a incidência global de recidiva local foi 2,4%. Nenhuma paciente do grupo de lipoenxertia apresentou recorrência local durante o período do estudo. Para recorrência sistêmica, as taxas obtidas foram de 3,7% (uma paciente) para o grupo lipoenxertia e 1,8% (três pacientes) para grupo da cirurgia conservadora sem reconstrução. não houve diferença significativa para recorrência local ou sistêmica nos grupos estudados.

Iodine-induced thyrotoxicosis--a case for subtotal thyroidectomy in severely ill patients.

PubMed

Köbberling, J; Hintze, G; Becker, H D

1985-01-02

Iodine-induced thyrotoxicosis (IIT), due to iodine application in high amounts in patients with circumscript or disseminated thyroid autonomy, is complicated by a prolonged course, mainly due on the body's resistance to conservative therapy with thiourea derivates. Therefore, we decided to perform subtotal thyroidectomy in 16 thyrotoxic patients. This is in contrast to the common opinion that surgery should only be performed after normalization of thyroid hormones. In all 16 patients with severe IIT, including three patients with thyroid storm, hormone levels decreased within a few days after surgery to normal or subnormal values and the clinical picture of thyrotoxicosis disappeared. In the case of thyroid storm the signs of disorientation normalized within 1-3 days. One patient died 5 weeks after surgery due to severe concomitant diseases. One patient exhibited transitory respiration distress and another had postoperative hypocalcaemia. In nine patients L-thyroxine replacement became necessary because of subclinical or clinical hypothyroidism. Only by this procedure will the high intrathyroidal storage of iodine and performed hormone be extracted. Surgery as a treatment for thyrotoxicosis should be reserved for patients with severe IIT, where conservative treatment has been shown to be ineffective. Furthermore, in rare selected cases, when a rapid normalization is required, surgery without preoperative treatment seems to be justified. The effect of surgery was impressive in all our cases and there were only minor perioperative complications. Thus, it could be shown that subtotal thyroidectomy may be a rational and effective treatment in severe IIT which should be carefully considered and weighed against other types of therapy.

The acquisition of data and public discussion of complications after therapeutic procedures and surgeries is a sensitive subject, which is mostly avoided even in department meetings. However, it is evident that the broad discussion and the expression of different opinions and aspects provide useful information for continuous improvements. Therefore, we established a system for the transparent acquisition of complications in our department. Since January 2005, we systematically register operative and non-operative complications at our department, evaluate them and therefore gain a great benefit. All the complications are presented, discussed and evaluated within the weekly morbidity and mortality conferences. In 2005 and 2006, among a total number of 2730 and, respectively, 3124 operations, 102 (3.7 %) and 71 (2.3 %) complications have been registered and analysed according to different criteria. We have distinguished between complications which required surgery and complications which only required conservative treatment. There was a higher number of complications which needed surgery. In this group, the most common complications have been found in vertebral spine surgery. The groups of complications with conservative treatment were mostly related to nerve lesions and deep venous thrombosis. With the aid of the internal department evaluation of the registered data, especially the number of complications in vertebral spine surgery could be clearly reduced in 2006. The described method has created a transparency of occurring complications because each colleague is informed as well as involved in the solution process. Furthermore, it is planned to evaluate the impact of risk factors on the various performed surgeries. © Georg Thieme Verlag KG Stuttgart · New York.

Glaucoma Drainage Device Erosion Following Ptosis Surgery.

Bae, Steven S; Campbell, Robert J

2017-09-01

To highlight the potential risk of glaucoma drainage device erosion following ptosis surgery. Case report. A 71-year-old man underwent uncomplicated superotemporal Ahmed glaucoma valve implantation in the left eye in 2008. Approximately 8 years later, the patient underwent bilateral ptosis repair, which successfully raised the upper eyelid position. Three months postoperatively, the patient's glaucoma drainage implant tube eroded through the corneal graft tissue and overlying conjunctiva to become exposed. A graft revision surgery was successfully performed with no further complications. Caution and conservative lid elevation may be warranted when performing ptosis repair in patients with a glaucoma drainage implant, and patients with a glaucoma implant undergoing ptosis surgery should be followed closely for signs of tube erosion.

A review of penile elongation surgery

PubMed Central

Gillis, Joshua

2017-01-01

Penile elongation surgery is less commonly performed in the public sector, but involves a collaborative approach between urology and plastic surgery. Congenital and acquired micropenis are the classic surgical indications for penile elongation surgery. The goal of intervention in these patients is to restore a functional penis size in order to allow normal standing micturition, enable satisfying sexual intercourse and improve patient quality of life. Many men seeking elongation actually have normal length penises, but perceive themselves to be small, a psychologic condition termed ‘penile dysmorphophobia’. This paper will review the anatomy and embryology of congenital micropenis and discuss both conservative and surgical management options for men seeking penile elongation therapy. PMID:28217452

We herein present three cases of abnormally expanded frontal sinuses (pneumoceles) with severe infection in patients with mental retardation and brain atrophy. Two patients previously underwent laryngotracheal separation surgery, and bacteriological examinations of purulent nasal discharge revealed infections caused by drug-resistant bacteria such as Pseudomonas aeruginosa and Acinetobacter baumannii. As conservative medical treatments were ineffective, all three patients were treated by computed tomography-guided endoscopic sinus surgery. This navigation system is useful for safer surgery in the area of anatomic deformity. The clinical findings, possible etiologies and surgical treatment of these cases are discussed.

2015-06-01

This study examines the quality of websites providing information on ulcerative colitis, including treatment options and surgery. Two search engines (Google and Yahoo) and the search term 'surgery for ulcerative colitis' were used. The first 50 sites obtained with each search engine were assessed. Sites were evaluated for content and scored using the DISCERN instrument, which evaluates the quality of health information on treatment choices. One hundred sites were examined, of which 14 were duplicates. Of the remainder, 58 provided patient-orientated information for adults and one site provided information for surgery in children. The other 27 sites included six scientific articles, three blogs, three links, six resources for clinicians, five fora, two video links and two dead links. Of the 58 websites that provided patient information for adults, only 26 (44.8%) had been updated within the last 2 years. Only 13/58 (22.4%) were affiliated to hospitals and clinics. Most sites (38/58, 65.5%) were associated with private companies with commercial interests. Although most websites contained information on symptoms and treatment options for ulcerative colitis, 37 (63.8%) did not describe any of the risks of surgery. Overall, only seven (12.1%) websites were identified as being 'good' or 'excellent' using the DISCERN criteria. The quality of patient information on surgery for ulcerative colitis is highly variable. There is potential for internet provision of valuable information and clinicians should guide patients with to access high-quality websites.

Recent advances in perforator flap surgical techniques have allowed for safe and reliable autologous tissue transfer with minimal donor-site morbidity. Between April 2012 and January 2013, we performed immediate breast reconstruction using free medial circumflex femoral artery perforator (MCFAP) flaps in 15 patients after breast-conserving surgery. The flaps were harvested from patients in the lithotomy position, while a second surgical team simultaneously conducted tumour resection. Of the 15 procedures performed, three flaps were dissected as true perforator flaps, while 12 flaps were dissected as muscle-sparing perforator flaps. The mean flap weight was 138.5 g (range, 77-230 g) and the mean pedicle length was 5.7 cm (range, 3.0-9.0 cm). Recipient vessels for anastomosis were serratus branches in 10 patients, internal mammary vessels in three patients and thoracodorsal vessels in two patients. The mean duration of surgery was 6.74 h (range, 5.65-9.45 h). There were no major complications requiring surgical intervention. Researchers observed partial flap necrosis, which manifested as small firm lesions in two patients, as well as local wound infection and dehiscence in one patient, which resolved spontaneously. There were no instances of donor-site seroma formation or lymphoedema in any of the patients. An objective assessment of postoperative photographs showed that cosmetic results were mostly satisfactory. Donor-site scars along the medial groin crease were inconspicuous and readily concealed by clothing. Given its reliable vascularity and minimal donor-site morbidity, the free MCFAP flap can be a good alternative for partial breast reconstruction after breast-conserving surgery.

Ossification of the posterior longitudinal ligament (OPLL) may produce quadriplegia. The course of future neurological deterioration in patients with radiographic evidence of OPLL, however, is not known. The authors conducted a long-term follow-up cohort study of more than 10 years to clarify the clinical course of this disease progression. A total of 450 patients, including 304 managed conservatively and 146 treated by surgery, were enrolled in the study. All patients underwent neurological and radiographical follow-up examinations for a mean of 17.6 years. Myelopathy was graded using Nurick classification and the Japanese Orthopaedic Association scale. Fifty-five (17%) of 323 patients without myelopathy evident at the first examination developed myelopathy during the follow-up period. Risk factors associated with the evolution of myelopathy included greater than 60% OPLL-induced stenotic compromise of the cervical canal, and increased range of motion of the cervical spine. Using Kaplan-Meier analysis, the myelopathy-free rate in patients without first-visit myelopathy was 71% after 30 years. A significant difference in final functional outcome was not observed between nonsurgical and surgical cases in which preoperative Nurick grades were 1 or 2. In patients with Nurick Grade 3 or 4 myelopathy, however, only 12% who underwent surgery eventually became wheelchair bound or bedridden compared with 89% of those managed conservatively. Surgery proved ineffective in the management of patients with Grade 5 disease. Results of this long-term cohort study elucidated the clinical course of OPLL following conservative or surgical management. Surgery proved effective for the management of patients with Nurick Grades 3 and 4 myelopathy.

Understanding conservationists' perspectives on the new-conservation debate.

A vibrant debate about the future direction of biodiversity conservation centers on the merits of the so-called new conservation. Proponents of the new conservation advocate a series of positions on key conservation ideas, such as the importance of human-dominated landscapes and conservation's engagement with capitalism. These have been fiercely contested in a debate dominated by a few high-profile individuals, and so far there has been no empirical exploration of existing perspectives on these issues among a wider community of conservationists. We used Q methodology to examine empirically perspectives on the new conservation held by attendees at the 2015 International Congress for Conservation Biology (ICCB). Although we identified a consensus on several key issues, 3 distinct positions emerged: in favor of conservation to benefit people but opposed to links with capitalism and corporations, in favor of biocentric approaches but with less emphasis on wilderness protection than prominent opponents of new conservation, and in favor of the published new conservation perspective but with less emphasis on increasing human well-being as a goal of conservation. Our results revealed differences between the debate on the new conservation in the literature and views held within a wider, but still limited, conservation community and demonstrated the existence of at least one viewpoint (in favor of conservation to benefit people but opposed to links with capitalism and corporations) that is almost absent from the published debate. We hope the fuller understanding we present of the variety of views that exist but have not yet been heard, will improve the quality and tone of debates on the subject. © 2016 The Authors.

2013-01-01

Purpose Early surgical management is the standard of care for penile fracture. Conservative treatment is an option with recent reports revealing lower success rates. We reviewed the data and long-term outcomes of patients with penile injury submitted to surgical or conservative treatment. Materials and Methods Between January 2004 and February 2012, 42 patients with penile blunt trauma on an erect penis were admitted to our center. We analyzed the following variables: age, etiology, symptoms and signs, diagnostic tests, treatment used, complications and erectile function during the follow-up. One patient was excluded due to missing information. Thirty-five patients underwent surgical repair and 6 patients were submitted to conservative management. Results Mean follow-up was 19.2 months (range, 7 days to 72 months). The mean elapsed time from trauma to surgery was 21.3±12.5 hours. Trauma during sexual relationship was the main cause (80.9%) of penile fracture. Urethral injury was present in five patients submitted to surgery. Dorsal vein injury occurred in three patients with false penile fracture and concomitant spongious corpus lesion was present in three patients. During follow-up, 31 cases (88.6%) of the surgical group and four cases (66.7%) of the conservative group reported sufficient erections for intercourse, with no voiding dysfunction and no penile curvature. However, the remaining two patients (33.3%) from the conservative group developed erectile dysfunction and three patients (50%) developed penile deviation. Conclusions Surgical approach provides excellent functional outcomes and lower complications. Early surgical management of penile fracture provides superior results and conservative approach should be avoided. PMID:23878691

Airway and Feeding Outcomes of Mandibular Distraction, Tongue-Lip Adhesion, and Conservative Management in Pierre Robin Sequence: A Prospective Study.

Pierre Robin sequence is characterized by mandibular retrognathia and glossoptosis resulting in airway obstruction and feeding difficulties. When conservative management fails, mandibular distraction osteogenesis or tongue-lip adhesion may be required to avoid tracheostomy. The authors' goal was to prospectively evaluate the airway and feeding outcomes of their comprehensive approach to Pierre Robin sequence, which includes conservative management, mandibular distraction osteogenesis, and tongue-lip adhesion. A longitudinal study of newborns with Pierre Robin sequence treated at a pediatric academic medical center between 2010 and 2015 was performed. Baseline feeding and respiratory data were collected. Patients underwent conservative management if they demonstrated sustainable weight gain without tube feeds, and if their airway was stable with positioning alone. Patients who required surgery underwent tongue-lip adhesion or mandibular distraction osteogenesis based on family and surgeon preference. Postoperative airway and feeding data were collected. Twenty-eight patients with Pierre Robin sequence were followed prospectively. Thirty-two percent had a syndrome. Ten underwent mandibular distraction osteogenesis, eight underwent tongue-lip adhesion, and 10 were treated conservatively. There were no differences in days to extubation or discharge, change in weight percentile, requirement for gastrostomy tube, or residual obstructive sleep apnea between the three groups. No patients required tracheostomy. The greatest reduction in apnea-hypopnea index occurred with mandibular distraction osteogenesis, followed by tongue-lip adhesion and conservative management. Careful selection of which patients with Pierre Robin sequence need surgery, and of the most appropriate surgical procedure for each patient, can minimize the need for postprocedure tracheostomy. A comprehensive approach to Pierre Robin sequence that includes conservative management, mandibular distraction osteogenesis, and tongue-lip adhesion can result in excellent airway and feeding outcomes.

An evidence-based strategy for the conservative management of the male patient with incontinence.

Newman, Diane K; Guzzo, Thomas; Lee, David; Jayadevappa, Ravishankar

2014-11-01

Incontinence is not an isolated symptom in men, but rather a component of a multifactorial problem that may include other lower urinary tract symptoms (LUTS). Male urinary incontinence is often seen following prostate surgery and procedures, particularly prostate cancer surgery. Men with enlarged prostates experience overactive bladder symptoms of urgency and frequency. Despite these bothersome lower urinary tract problems in men, conservative treatment remains poorly investigated. This review will provide the current evidence-based strategies for the use of conservative management in men with urinary incontinence and other LUTS. Conservative treatment for urinary incontinence is an effective intervention and has been recommended by the evidence-based guidelines as the first-line intervention for LUTS. Despite this prevalence, the only population of men who continue to receive systematic consideration with respect to conservative management are those with postprostatectomy urinary symptoms. Although continence status gradually improves in the ensuing weeks and months, evidence-based research has shown that preoperative and early postoperative pelvic floor muscle training can speed the recovery of continence in the short and long term. Recent research has also shown that behavioral therapy combined with medication can improve the male symptom of nocturia. Lifestyle changes of weight loss in obese men with diabetes and LUTS and dietary modification has also been shown to be effective. Although sparse, there are data to support conservative interventions as the first-line treatment in men with LUTS. There is a strong recommendation for implementing a pelvic floor muscle training (PFMT) program before and after prostatectomy. Positive lifestyle changes such as weight loss in obese men and dietary modification can lessen urgency, nocturia, and incontinence. Despite this growing evidence on effectiveness, urologists rarely recommend conservative treatment to patients.

Orthopaedic podiatry triage: process outcomes of a skill mix initiative.

Homeming, Lyndon J; Kuipers, Pim; Nihal, Aneel

2012-11-01

The Orthopaedic Podiatry Triage Clinic (OPodTC) is a 'skill mix' model of care developed in Queensland Health to address the problem of lengthy waiting times for orthopaedic surgery on foot and ankle pathologies. It is based on the recognition that many orthopaedic surgery referrals can be identified early and treated conservatively with podiatry, averting the need for more costly and invasive surgical interventions. The model is collaborative and relies on screening and triage by the podiatrist, rather than delegation by the orthopaedic surgeon. Screening and triage through OPodTC was trialled at three Queensland Health hospital facilities during 2009 and 2010 to improve service timeliness. Patients identified by the OPodTC podiatrist as suitable for conservative management were provided with non-surgical podiatry interventions and discharged if appropriate. Those identified as still requiring surgical intervention after the benefit of interim conservative treatment provided by the podiatrist (or who chose to remain on the list) were returned to their previous place on the orthopaedic waiting list. This paper presents a summary and description of waiting list changes in association with this trial. The OPodTC intervention resulted in a reduction in the non-urgent category of the waiting list across the three hospitals of between 23.3% and 49.7%. Indications from wait-list service data demonstrated increased timeliness and improved patient flow, which are core goals of these skill mix initiatives. This study highlights the potential of screening and triage functions in the skill mix debate. In this example, conservative treatment options were considered first, suitable patients did not have to wait long periods to receive timely and appropriate interventions, and those for whom surgery was indicated, were provided with a more targeted service.

Chronic granulomatous disease (CGD) is a primary immunodeficiency characterized by serious infections and inflammation. It can be managed conservatively with prophylactic antimicrobial agents or curatively with hematopoietic stem cell transplantation (HSCT). In the United Kingdom and Ireland there are cohorts of children managed both conservatively and curatively. This study aimed to compare clinical outcomes (mortality and morbidity) in children managed conservatively and curatively. Children were identified from specialist centers and advertising through special interest groups. Clinical data were collected from medical records regarding infections, inflammatory complications and growth, other admissions, and curative treatment. Comparisons were made for patients not undergoing HSCT and patients after HSCT. Seventy-three living children were identified, 59 (80%) of whom were recruited. Five deceased children were also identified. Clinical information was available for 62 children (4 deceased). Thirty (48%) children had undergone HSCT. Children who did not undergo transplantation had 0.71 episodes of infection/admission/surgery per CGD life year (95% CI, 0.69-0.75 events per year). Post-HSCT children had 0.15 episodes of infection/admission/surgery per transplant year (95% CI, 0.09-0.21 events per year). The mean z score for height and body mass index (BMI) for age was significantly better in post-HSCT children. Survival in the non-HSCT group was 90% at age 15 years. Survival in the post-HSCT group was 90%. Children with CGD not undergoing transplantation have more serious infections, episodes of surgery, and admissions compared with post-HSCT children. Children undergoing transplantation have better height for age. Survival is good at the end of the pediatric age range and also after HSCT.

To understand the threat posed by localized prostate cancer and the potential impact of surgery or radiation, patients and healthcare providers require information on long-term outcomes following conservative management. To describe 15-yr survival outcomes and cancer therapy utilization among men 65 years and older managed conservatively for newly diagnosed localized prostate cancer. This is a population-based cohort study with participants living in predefined geographic areas covered by the Surveillance, Epidemiology, and End Results program. The study includes 31 137 Medicare patients aged ≥65 yr diagnosed with localized prostate cancer in 1992-2009 who initially received conservative management (no surgery, radiotherapy, cryotherapy, or androgen deprivation therapy [ADT]). All patients were followed until death or December 31, 2009 (for prostate cancer-specific mortality [PCSM]) and December 31, 2011 (for overall mortality). Competing-risk analyses were used to examine PCSM, overall mortality, and utilization of cancer therapies. The 15-yr risk of PCSM for men aged 65-74 yr diagnosed with screening-detected prostate cancer was 5.7% (95% confidence interval [CI] 3.7-8.0%) for T1c Gleason 5-7 and 22% (95% CI 16-35%) for Gleason 8-10 disease. After 15 yr of follow-up, 24% (95% CI 21-27%) of men aged 65-74 yr with screening-detected Gleason 5-7 cancer received ADT. The corresponding result for men with Gleason 8-10 cancer was 38% (95% CI 32-44%). The major study limitations are the lack of data for men aged <65 yr and detailed clinical information associated with secondary cancer therapy. The 15-yr outcomes following conservative management of newly diagnosed Gleason 5-7 prostate cancer among men aged ≥65 yr are excellent. Men with Gleason 8-10 disease managed conservatively face a significant risk of PCSM. We examined the long-term survival outcomes for a large group of patients diagnosed with localized prostate cancer who did not have surgery, radiotherapy, cryotherapy, or androgen deprivation therapy in the first 6 mo after cancer diagnosis. We found that the 15-yr disease-specific survival is excellent for men diagnosed with Gleason 5-7 disease. The data support conservative management as a reasonable choice for elderly patients with low-grade localized prostate cancer. Copyright © 2015 European Association of Urology.

2016-12-01

The purpose of this case report is to describe the chiropractic management of a patient with postoperative perineal numbness as a result of hip arthroscopy. A female patient presented to a chiropractic clinic with 7 weeks of ongoing perineal numbness after right hip arthroscopic surgery with labral repair. The patient reported lack of sensation during urination, sexual intercourse, and the insertion and removal of female hygienic products into the vagina. Conservative care included myofascial therapy to the psoas and obturator internus muscles and instrument-assisted soft tissue mobilization over the obturator internus. Manual manipulation to the pelvis was also performed. The patient reported complete resolution of perineal numbness after 3 chiropractic treatments. With conservative chiropractic management, full resolution of sensation for this patient was achieved.

Analysis of observational cohort data is subject to bias from unobservable risk selection. We compared econometric models and treatment effectiveness estimates using the linked Surveillance, Epidemiology, and End Results (SEER)-Medicare claims data for women diagnosed with ductal carcinoma in situ. Treatment effectiveness estimates for mastectomy and breast conserving surgery (BCS) with or without radiotherapy were compared using three different models: simultaneous-equations model, discrete-time survival model with unobserved heterogeneity (frailty), and proportional hazards model. Overall trends in disease-free survival (DFS), or time to first subsequent breast event, by treatment are similar regardless of the model, with mastectomy yielding the highest DFS over 8 years of follow-up, followed by BCS with radiotherapy, and then BCS alone. Absolute rates and direction of bias varied substantially by treatment strategy. DFS was underestimated by single-equation and frailty models compared to the simultaneous-equations model and RCT results for BCS with RT and overestimated for BCS alone. PMID:21602195

A Regression Model for Predicting Shape Deformation after Breast Conserving Surgery

2018-01-01

Breast cancer treatments can have a negative impact on breast aesthetics, in case when surgery is intended to intersect tumor. For many years mastectomy was the only surgical option, but more recently breast conserving surgery (BCS) has been promoted as a liable alternative to treat cancer while preserving most part of the breast. However, there is still a significant number of BCS intervened patients who are unpleasant with the result of the treatment, which leads to self-image issues and emotional overloads. Surgeons recognize the value of a tool to predict the breast shape after BCS to facilitate surgeon/patient communication and allow more educated decisions; however, no such tool is available that is suited for clinical usage. These tools could serve as a way of visually sensing the aesthetic consequences of the treatment. In this research, it is intended to propose a methodology for predict the deformation after BCS by using machine learning techniques. Nonetheless, there is no appropriate dataset containing breast data before and after surgery in order to train a learning model. Therefore, an in-house semi-synthetic dataset is proposed to fulfill the requirement of this research. Using the proposed dataset, several learning methodologies were investigated, and promising outcomes are obtained. PMID:29315279

Lumbar spinal stenosis (LSS) may result from degenerative changes of the spine, which lead to neural ischemia, neurogenic claudication, and a significant decrease in quality of life. Treatments for LSS range from conservative management including epidural steroid injections (ESI) to laminectomy surgery. Treatments vary greatly in cost and success. ESI is the least costly treatment may be successful for early stages of LSS but often must be repeated frequently. Laminectomy surgery is more costly and has higher complication rates. Minimally invasive lumbar decompression (mild(®) ) is an alternative. Using a decision-analytic model from the Medicare perspective, a cost-effectiveness analysis was performed comparing mild(®) to ESI or laminectomy surgery. The analysis population included patients with LSS who have moderate to severe symptoms and have failed conservative therapy. Costs included initial procedure, complications, and repeat/revision or alternate procedure after failure. Effects measured as change in quality-adjusted life years (QALY) from preprocedure to 2 years postprocedure. Incremental cost-effectiveness ratios were determined, and sensitivity analysis conducted. The mild(®) strategy appears to be the most cost-effective ($43,760/QALY), with ESI the next best alternative at an additional $37,758/QALY. Laminectomy surgery was the least cost-effective ($125,985/QALY). © 2014 World Institute of Pain.

Shoulder pain is common in society, with high prevalence in the general population. Shoulder impingement syndrome (SIS) is the most frequent cause. Patients suffer pain, muscle weakness and loss of movement in the affected joint. Initial treatment is predominantly conservative. The surgical option has high success rates and is often used when conservative strategy fails. Traditional physiotherapy and post-operative exercises are needed for the recovery of joint range, muscle strength, stability and functionality. Telerehabilitation programmes have shown positive results in some orthopaedic conditions after surgery. Customized telerehabilitation intervention programmes should be developed to recover shoulder function after SIS surgery. The objective of this study is to evaluate the feasibility and effectiveness of a telerehabilitation intervention compared with usual care in patients after subacromial decompression surgery. We will compare an intervention group receiving videoconferences and a telerehabilitation programme to a control group receiving traditional physiotherapy intervention in a single-blind, randomized controlled non-inferiority trial study design. Through this study, we will further develop our preliminary data set and practical experience with the telerehabilitation programmes to evaluate their effectiveness and compare this with traditional intervention. We will also explore patient satisfaction and cost-effectiveness. Patient enrolment is ongoing. ClinicalTrials.gov, NCT02909920 . 14 September 2016.

Is breast conservative surgery a reasonable option in multifocal or multicentric tumors?

The incidence of multifocal (MF) and multicentric (MC) carcinomas varies widely among clinical studies, depending on definitions and methods for pathological sampling. Magnetic resonance imaging is increasingly used because it can help identify additional and conventionally occult tumors with high sensitivity. However, false positive lesions might incorrectly influence treatment decisions. Therefore, preoperative biopsies must be performed to avoid unnecessary surgery. Most studies have shown higher lymph node involvement rates in MF/MC tumors than in unifocal tumors. However, the rate of local recurrences is usually low after breast conservative treatment (BCT) of MC/MF tumors. It has been suggested that BCT is a reasonable option for MC/MF tumors in women aged 50-69 years, with small tumors and absence of extensive ductal carcinoma in situ. A meta-analysis showed an apparent decreased overall survival in MC/MF tumors but data are controversial. Surgery should achieve both acceptable cosmetic results and negative margins, which requires thorough preoperative radiological workup and localization of lesions. Boost radiotherapy techniques must be evaluated since double boosts might result in increased toxicity, namely fibrosis. In conclusion, BCT is feasible in selected patients with MC/MF but the choice of surgery must be discussed in a multidisciplinary team comprising at least radiologists, surgeons and radiotherapists.

Recent literature strongly challenged indications to perform preventive surgery in unruptured arteriovenous malformation (AVM) claiming that invasive AVM treatment is associated with a significant risk of complications and thus conservative management may be a preferable alternative in many patients. On the other hand, the recent improvement of surgical instrumentation and treatment strategies (both surgical and interventional) yielded better outcomes than those achieved only a decade ago. Therefore, even among specialists, a wide variety of opinions, concerning the treatment of unruptured AVM, can be found. This multicenter retrospective study analyzes a consecutive series of 545 surgically treated AVMs in 10 different hospitals in Italy. Patients with AVMs treated after hemorrhage had an unfavorable (modified Rankin Scale score >1) outcome in more than one third (37.69%) of the cases. Conversely, with proper indications, unruptured AVMs treated preventively have a good outcome in 93.8% of cases, increasing to 95.7%, with no death, if only Spetzler-Martin grades 1-3 are considered (P < 0.05). Outcomes on discharge significantly (P < 0.05) improve at 6 months with the disappearance of many of the initial neurologic deficits that turn out to be transient. In unruptured low-risk AVMs (Spetzler-Martin grades 1-3), over time, the risk of surgery-associated neurologic deficits becomes lower than that linked to spontaneous hemorrhage, with a crossover point at 6.5 years. Because the average bleeding age is less than 45 years, preventive surgery can be advocated to safeguard the patient and overcome the risks associated with the natural history of AVMs. Copyright © 2017 Elsevier Inc.

To investigate the clinical relevance of the classification systems used for temporal bone osteoradionecrosis (ORN) and to define a treatment protocol for temporal bone ORN. Retrospective case series. Amsterdam, department of otorhinolaryngology and head and neck surgery. Classification of temporal bone ORN was performed through use of clinical data and radiologic imaging. Outcomes of conservative and surgical treatment were investigated and compared for different grades of ORN. Of the 49 ears included in this study, 35 were primarily treated conservatively. At start of conservative treatment, 23 were classified as a localized and 8 as a diffuse form of ORN; 4 could not be classified. There was a significant difference in clinical outcome between the localized and diffuse forms of ORN (χ(2) = 5.862, P = .015), and mastoid air cell destruction on preoperative computed tomography scan was found to be a significant predictor for a negative outcome of conservative treatment (χ(2) = 4.34, P = .037). Fourteen ears with diffuse ORN were primarily treated surgically, and 11 were secondarily treated surgically following a period of conservative treatment. Twenty-two patients were treated with subtotal petrosectomy, of which 20 were cured. Three patients were treated with canal wall down mastoidectomy, and 2 had recurrence of disease. Ramsden's classification system is clinically relevant in predicting conservative treatment outcomes. Mastoid air cell destruction on computed tomography differentiates between the localized and diffuse forms of ORN. Given our results and experience with treating temporal bone ORN, we propose a treatment protocol. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

Atlantoaxial rotatory fixation as a rare complication from head positioning in otologic surgery: Report of two cases in young children.

Sakaida, Hiroshi; Akeda, Koji; Sudo, Akihiro; Takeuchi, Kazuhiko

2017-01-01

Atlantoaxial rotatory fixation is a condition in which the first and second vertebrae of the cervical spine become interlocked in a rotated position. This condition can result in serious consequences and thus have a significant impact on patients, especially when diagnosis and treatment are delayed. Some cases of atlantoaxial rotatory fixation have been described in association with otologic surgery or plastic surgery involving the ear. We present the cases of two pediatric patients who developed atlantoaxial rotatory fixation following otologic surgery and we review the relevant literature. One patient was a 7-year-old boy who underwent tympanoplasty for cholesteatoma. The other patient was a 5-year-old girl with profound sensorineural hearing loss who underwent cochlear implantation. Both patients developed atlantoaxial rotatory fixation on the day after surgery, and they were treated conservatively. Our literature search using relevant terms identified 12 similar published cases. Thus, a total of 14 patients, including our 2 patients, were evaluated. Most of the patients were children and typically they complained of painful torticollis and exhibited a characteristic posture called the "cock-robin" position on the day after surgery. Mostly, the direction of torticollis was opposite to the side of surgery. Most of the patients received conservative treatment alone, but three underwent surgical treatment. The correlation between the direction of torticollis and the side of surgery suggests that rotation of the head during surgery has an impact on development of postoperative atlantoaxial rotatory fixation. Thus, children undergoing otologic surgery are thought to be at a risk of postoperative atlantoaxial rotatory fixation. Although rare, the surgical team needs to be aware of this adverse event and pay close attention to this possibility throughout the perioperative period. Perioperative management should include informed consent, preoperative assessment of the range of head and neck motion, proper intraoperative positioning and monitoring of the position, and postoperative follow-up. Postoperative atlantoaxial rotatory fixation is not completely preventable, but good perioperative management can minimize the damage resulting from this condition.

Introduction The care of patients with breast cancer is extremely complex and requires interdisciplinary care in certified facilities. These specialized facilities provide numerous services without being correspondingly remunerated. The question whether breast cancer surgery should be performed in an outpatient setting to reduce costs is increasingly being debated. This study compares inpatient surgical treatment with a model of the same surgery performed on an outpatient basis to examine the potential financial impact. Material and Methods A theoretical model was developed and the DRG fees for surgical interventions to treat primary breast cancer were calculated. A theoretical 1-day DRG was then calculated to permit comparisons with outpatient procedures. The costs of outpatient surgery were calculated based on the remuneration rates of the AOP (Outpatient Surgery) Contract and the EBM (Uniform Assessment Scale) and compared to the costs of the 1-day DRG. Results The DRG fee for both breast-conserving surgery and mastectomy is higher than the fee paid in the context of the EBM system, although the same procedures were carried out in both systems. If a hospital were to carry out breast-conserving surgery as an outpatient procedure, the fee would be € 1313.81; depending on the type of surgery, the hospital would therefore only receive between 39.20% and 52.82% of the DRG fee. This was the case even for a 1-day treatment. Compared to the real DRG fees the difference would be even more striking. Conclusion Carrying out breast cancer surgery as an outpatient procedure would result in a significant shortfall of revenues. Additional services from certified centers, such as the interdisciplinary planning of treatment, psycho-oncological and social-medical care with the involvement of relatives, detailed documentation, etc., which are currently provided without surcharge or adequate remuneration, could no longer be maintained. The quality of processes and excellent results which have been achieved and ultimately the care given by certified facilities would be significantly at risk. PMID:28845052

To examine the prevalence and content of robotic surgery information presented on websites of U.S. hospitals. We completed a systematic analysis of 400 randomly selected U.S. hospital websites in June of 2010. Data were collected on the presence and location of robotic surgery information on a hospital's website; use of images or text provided by the manufacturer; use of direct link to manufacturer website; statements of clinical superiority; statements of improved cancer outcome; mention of a comparison group for a statement; citation of supporting data and mention of specific risks. Forty-one percent of hospital websites described robotic surgery. Among these, 37% percent presented robotic surgery on their homepage, 73% used manufacturer-provided stock images or text, and 33% linked to a manufacturer website. Statements of clinical superiority were made on 86% of websites, with 32% describing improved cancer control, and 2% described a reference group. No hospital website mentioned risks. Materials provided by hospitals regarding the surgical robot overestimate benefits, largely ignore risks and are strongly influenced by the manufacturer. © 2011 National Association for Healthcare Quality.

2015-10-01

Tendinopathy of the Achilles tendon involves clinical conditions in and around the tendon and it is the result of a failure of a chronic healing response. Although several conservative therapeutic options have been proposed, few of them are supported by randomized controlled trials. The management is primarily conservative and many patients respond well to conservative measures. If clinical conditions do not improve after 6 months of conservative management, surgery is recommended. The management of chronic ruptures is different from that of acute ruptures. The optimal surgical procedure is still debated. In this article chronic Achilles tendon disorders are debated and evidence-based medicine treatment strategies are discussed.

Vaginal carcinoma is a rare gynecological malignancy that is usually treated by radiation therapy and/or surgery combined with chemotherapy. Here, we report a case of invasive vaginal carcinoma in a young woman who underwent fertility-sparing treatment involving neoadjuvant chemotherapy and conservative surgery. A 36-year-old non-parous woman had a solid tumor in the vagina. Positron emission tomography/computed tomography showed a tumor in the vagina with high FDG uptake (SUV = 17.33) but no metastatic lesions. The patient was diagnosed with vaginal squamous cell carcinoma, FIGO stage I, T1N0M0. Because she wished to retain her fertility, neoadjuvant chemotherapy consisting of irinotecan hydrochloride and nedaplatin was initiated. After four courses of chemotherapy, partial vaginectomy was carried out and the pathological diagnosis of the residual lesion was VAIN 3. Following two further courses of the same chemotherapy, she obtained complete response, and has shown no evidence of disease for 14 months. © 2014 The Authors.

In early mandatory Israel, orthopedics was mainly conservative, The first modern orthopedic surgeon was Ernst Spira from Czechoslovakia who established an orthopedic service at the Beilinson Hospital in Petah Tikva and left in 1948 to establish the Orthopedic Department and the Rehabilitation Center in Tel Hashomer, which treated the War of Independence casualties including amputees and victims of spinal cord injuries. A second orthopedic department was opened in Tel Hashomer by Shmuel Weissman who left in 1961 to open the Orthopedic Department at the Ichilov hospital in Tel Aviv. Shmuel Weissman became the first Chairman of Orthopedic Surgery at the Tel Aviv University medical school. In 1955, Myer Makin opened a modern orthopedic department in the Hadassah Hospital in Jerusalem and the Alyn Hospital for crippled children. In 1951, Assaf Harofeh Hospital opened the Department of Orthopedic Surgery headed by Anatol Axer who specialized in the treatment and rehabilitation of polio patients. The majority of the second generation of orthopedic department directors was trained by these four surgeons. Major developments in the 1960s and 1970s were the introduction of the AO system revolutionizing fracture treatment from conservative to operative treatment, the advent of total hip and knee replacements, Harrington instrumentation in spinal surgery and arthroscopy were major advances in orthopedic patient care brought to Israel by the aforementioned second generation of orthopedic surgeons. Hand surgery became an independent subspecialty of orthopedics and was lead by the internationally renowned hand surgeon, Isidore Kessler.

To describe the proportion of women who anticipate having breast-conserving surgery (BCS) versus modified radical mastectomy (MRM), the factors they considered when making treatment choices, the degree to which they perceived they had participated in and had control of the treatment decision, and to explore factors associated with type of planned surgery. Prospective cohort study conducted among patients attending a tertiary care hospital in Alberta, Canada from 1992 to 1995. Participants had a first diagnosis of localized unilateral breast cancer, and were, in the opinions of their surgeons, candidates for either BCS or MRM. Of 157 participants, 71.3% anticipated having BCS and 28.7% anticipated MRM. Referents perceived to play an important role in decision making included self, doctor, and significant other. The two top-ranked items perceived to have influenced treatment choice were doctor's advice and possibility of complete cure. Most women (60%) participated in treatment choice to the degree that they preferred, but only 13.6% received their preferred amount of information. The type of planned surgery was predicted by surgeon, contribution of doctor to choice of treatment, importance of breasts to sexuality, self-efficacy, and concerns about cancer recurrence from a multivariable logistic regression model. Both patient and surgeon factors are important predictors of type of planned surgery. There is a gap between women's preferences and actual experiences with regard to information provided and patient participation in treatment choices, with women's desire for more information about their treatment being most prevalent.

Functional and aesthetic outcome after breast-conserving surgery are vital endpoints for patients with primary breast cancer. A large variety of oncoplastic techniques exist; however, it remains unclear which techniques yield the highest rates of local control at first surgery, omission of reexcision or subsequent mastectomy, and merits the highest degree of patient satisfaction. In this retrospective case cohort trial with a customized investigational questionnaire for assessment of patient satisfaction with the surgical result, we analyzed 1,035 patients with primary, unilateral breast cancer and oncoplastic surgery from 2004 to 2009. Analysis of patient reported outcome (PRO) revealed that 88 % of the cohort was satisfied with their aesthetic result using oncoplastic techniques following the concept presented. These results also were achieved in difficult tumor localizations, such as upper inner and lower inner quadrant. Conversion rate from breast-conserving therapy to secondary mastectomy was low at 7.2 % (n = 68/944 patients). The systematization of oncoplastic techniques presented-embedded in a multimodal concept of breast cancer therapy-facilitates tumor control with a few number of uncomplicated techniques adapted to tumor site and size with a median resection of 32 (range 11-793) g. Five-year recurrence rate in our cohort was 4.0 %. Patient's satisfaction was independent from age, body mass index, resection volume, tumor localization, and type of oncoplastic surgery (p > 0.05). We identified postoperative pain as an important negative impact factor on patient's satisfaction with the aesthetic result (p = 0.0001).

OBJECTIVE This study aimed to determine the prognostic value of MRI variables to predict outcome in patients with herniated disc-related sciatica, and whether MRI could facilitate the decision making between early surgery and prolonged conservative care in these patients. METHODS A prospective observational evaluation of patients enrolled in a randomized trial with 1-year follow-up was completed. A total of 283 patients with sciatica who had a radiologically confirmed disc herniation were randomized either to surgery or to prolonged conservative care with surgery if needed. Outcome measures were recovery and leg pain severity. Recovery was registered on a 7-point Likert scale. Complete/near complete recovery was considered a satisfactory outcome. Leg pain severity was measured on a 0- to 100-mm visual analog scale. Multiple MRI characteristics of the degenerated disc herniation were independently scored by 3 spine experts. Cox models were used to study the influence of MRI variables on rate of recovery, and linear mixed models were used to determine the predictive value of MRI variables for leg pain severity during follow-up. The interaction of each MRI predictor with treatment allocation was tested. There were no study-specific conflicts of interest. RESULTS Baseline MRI variables associated with less leg pain severity were the reader's assessment of presence of nerve root compression (p < 0.001), and assessment of extrusion compared with protrusion of the disc herniation (p = 0.006). Both variables tended to be associated, but not significantly, with satisfactory outcome during follow-up (HR 1.45, 95% CI 0.93-2.24, and HR 1.24, 95% CI 0.96-1.61, respectively). The size of disc herniation at baseline was not associated with outcome. There was no significant change in the effects between treatment groups. CONCLUSIONS MRI assessment of the presence of nerve root compression and extrusion of a herniated disc at baseline was associated with less leg pain during 1-year follow-up, irrespective of a surgical or conservative treatment. MRI findings seem not to be helpful in determining which patients might fare better with early surgery compared with a strategy of prolonged conservative care.

In 2014, SSO-ASTRO published guidelines which recommended "no ink on tumor" as adequate margins for patients undergoing breast conservation for invasive breast cancer. In 2016, new SSO-ASTRO-ASCO guidelines recommended 2 mm margins for DCIS. We evaluated whether these guidelines affected re-excision rates at our institution. Patients treated with breast conservation surgery from January 1, 2010-March 1, 2016 were identified. Re-excision rates, tumor characteristics, and presence of residual disease were recorded. The 2016 guidelines were retrospectively applied to the same cohort and expected re-excision rates calculated. Re-excision rates did not significantly decline before and after 2014 guideline adoption (11.9% before, 10.9% after; p = 0.65) or when the 2016 guidelines were retrospectively applied (8.4%; p = 0.10). The 2014 and 2016 guidelines had minimal impact on our re-excision rates, as most re-excisions were done for DCIS and 2016 guidelines supported our prior institutional practices of 2 mm margins for these patients.

Hung, W K; Ying, M; Chan, C M; Lam, H S; Mak, K L

2009-01-01

Minimally invasive surgery is gaining popularity around the world because it achieves the same or even superior results when compared to standard surgery but with less morbidity. Minimally invasive breast surgery is a broad concept encompassing new developments in the field of breast surgery that work on this minimally invasive principle. In this regard, breast-conserving surgery and sentinel lymph node biopsy are good illustrations of this concept. There are three major areas of progress in the minimally invasive management of breast disease. First, percutaneous excisional devices are now available that can replace the surgical excision of breast mass lesions. Second, various ablative treatments are capable of destroying breast cancers in situ instead of surgical excision. Third, mammary ductoscopy provides a new approach to the investigation of mammary duct pathology. Clinical experience and potential applications of these new technologies are reviewed.

Colorectal fecaloma is hardening of feces into lumps of varying size that is much harder in consistency than a fecal impaction. Complications of colorectal fecaloma include ulceration, bleeding, perforation and obstruction of the colon. Most fecalomas are successfully removed by conservative treatment with laxatives, enemas and rectal evacuation to relieve fecal impaction. When conservative treatments have failed, a surgical intervention may be needed. Herein, we report a case of 4.7 cm sized sigmoid fecaloma showing no response to conservative treatments that was successfully removed by endoscopic fragmentation with Coca-Cola injection instead of surgery.

The Internet is a common resource for applicants of hand surgery fellowships, however, the quality and accessibility of fellowship online information is unknown. The objectives of this study were to evaluate the accessibility of hand surgery fellowship Web sites and to assess the quality of information provided via program Web sites. Hand fellowship Web site accessibility was evaluated by reviewing the American Society for Surgery of the Hand (ASSH) on November 16, 2014 and the National Resident Matching Program (NRMP) fellowship directories on February 12, 2015, and performing an independent Google search on November 25, 2014. Accessible Web sites were then assessed for quality of the presented information. A total of 81 programs were identified with the ASSH directory featuring direct links to 32% of program Web sites and the NRMP directory directly linking to 0%. A Google search yielded direct links to 86% of program Web sites. The quality of presented information varied greatly among the 72 accessible Web sites. Program description (100%), fellowship application requirements (97%), program contact email address (85%), and research requirements (75%) were the most commonly presented components of fellowship information. Hand fellowship program Web sites can be accessed from the ASSH directory and, to a lesser extent, the NRMP directory. However, a Google search is the most reliable method to access online fellowship information. Of assessable programs, all featured a program description though the quality of the remaining information was variable. Hand surgery fellowship applicants may face some difficulties when attempting to gather program information online. Future efforts should focus on improving the accessibility and content quality on hand surgery fellowship program Web sites.

Controllability of flow-conservation networks

The ultimate goal of exploring complex networks is to control them. As such, controllability of complex networks has been intensively investigated. Despite recent advances in studying the impact of a network's topology on its controllability, a comprehensive understanding of the synergistic impact of network topology and dynamics on controllability is still lacking. Here, we explore the controllability of flow-conservation networks, trying to identify the minimal number of driver nodes that can guide the network to any desirable state. We develop a method to analyze the controllability on flow-conservation networks based on exact controllability theory, transforming the original analysis on adjacency matrix to Laplacian matrix. With this framework, we systematically investigate the impact of some key factors of networks, including link density, link directionality, and link polarity, on the controllability of these networks. We also obtain the analytical equations by investigating the network's structural properties approximatively and design the efficient tools. Finally, we consider some real networks with flow dynamics, finding that their controllability is significantly different from that predicted by only considering the topology. These findings deepen our understanding of network controllability with flow-conservation dynamics and provide a general framework to incorporate real dynamics in the analysis of network controllability.

Lumbar foraminal stenosis, the hidden stenosis including at L5/S1.

2016-10-01

In patients with lower back and leg pain, lumbar foraminal stenosis (LFS) is one of the most important pathologies, especially for predominant radicular symptoms. LFS pathology can develop as a result of progressing spinal degeneration and is characterized by exacerbation with foraminal narrowing caused by lumbar extension (Kemp's sign). However, there is a lack of critical clinical findings for LFS pathology. Therefore, patients with robust and persistent leg pain, which is exacerbated by lumbar extension, should be suspected of LFS. Radiological diagnosis is performed using multiple radiological modalities, such as magnetic resonance imaging, including plain examination and novel protocols such as diffusion tensor imaging, as well as dynamic X-ray, and computed tomography. Electrophysiological testing can also aid diagnosis. Treatment options include both conservative and surgical approaches. Conservative treatment includes medication, rehabilitation, and spinal nerve block. Surgery should be considered when the pathology is refractory to conservative treatment and requires direct decompression of the exiting nerve root, including the dorsal root ganglia. In cases with decreased intervertebral height and/or instability, fusion surgery should also be considered. Recent advancements in minimally invasive lumbar lateral interbody fusion procedures enable effective and less invasive foraminal enlargement compared with traditional fusion surgeries such as transforaminal lumbar interbody fusion. The lumbosacral junction can cause L5 radiculopathy with greater incidence than other lumbar levels as a result of anatomical and epidemiological factors, which should be better addressed when treating clinical lower back pain.

Hepatic trauma is a rare surgical emergency with significant morbidity and mortality. Extensive experience in liver surgery is a prerequisite for the management of these injuries. The medical records of 68 consecutive patients with hepatic trauma were retrospectively reviewed for the severity of liver injury, management, morbidity, mortality, and risk factors. Of the patients, 14 were treated conservatively and 52 surgically (24 suture/fibrin glue, 16 perihepatic packing, 11 resections, 1 liver transplantation). Two patients died just before emergency surgery could be performed. Overall mortality was 21% (14/68), and 13, 14, 6, 27, and 50% for types I, II, III, IV, and V injuries, respectively. Only nine deaths (all type IV and V) were liver related, while four were caused by extrahepatic injuries and one by concomitant liver cirrhosis. With respect to treatment, conservative management, suture, and resection had a low mortality of 0, 4, and 9%, respectively. In contrast, mortality was 47% in patients in whom only packing was performed (in severe injuries). Stepwise multivariate regression analysis proved prothrombin values <40%, ISS scores >30, and transfusion requirements of more than 10 red packed cells to be significant risk factors for post-traumatic death. Type I-III hepatic injuries can safely be treated by conservative or simple surgical means. However, complex hepatic injuries (types IV and V) carry a significant mortality and may require hepatic surgery, including liver resection or even transplantation. Therefore, patients with severe hepatic injuries should be treated in a specialized institution.

Surgical treatment of constipation and obstructed defecation (OD) carries frequent recurrences, as OD is an 'iceberg syndrome' characterized by 'underwater rocks' or occult diseases which may affect the outcome of surgery. The aim of this study was to evaluate occult disorders in order to alert the clinician of these and minimize failures. One hundred consecutive constipated patients with OD symptoms, 81 female patients, median age 52 years, underwent perineal examination, proctoscopy, anorectal manometry, and anal/vaginal ultrasound. Anorectal physiology and imaging tests were also carried out when indicated, as well as psychological and urogynaecological consultation. Symptoms were graded using a modified 1-20 constipation score. Both evident (e.g. rectocele) and occult (e.g. anismus) diseases were prospectively evaluated using a novel 'iceberg diagram'. The type of treatment, whether conservative or surgical, was also recorded. Fifty-four (54%) patients had both mucosal prolapse and rectocele. All patients had at least two occult OD-related diseases, 66 patients had at least three: anxiety-depression, anismus and rectal hyposensation were the most frequent (66%, 44% and 33% respectively). The median constipation score was 11 (range 2-20), the median number of 'occult disorders' was 5 (range 2-8). Conservative treatment was carried out in most patients. Surgery was carried out in 14 (14%) patients. The novel 'iceberg diagram' allowed the adequate evaluation of OD-related occult diseases and better selection of patients for treatment. Most were managed conservatively, and only a minority were treated by surgery.

Minimalist breast conserving surgical approaches for inferiorly sited cancers.

PubMed

Tan, Mona P

2017-08-01

Contemporary data suggests that breast conservation treatment (BCT) may confer a survival advantage when compared to mastectomy. Hence, it would be logical to adopt strategies which increase eligibility of successful BCT without compromising oncologic principles or cosmetic outcome. With respect to achieving good aesthetics, inferiorly sited breast cancers pose a particular technical challenge. A vast array of techniques, collectively referred to as oncoplastic breast surgery (OBS) have been developed to minimise post treatment distortion. The purported advantages of these approaches are the acquisition of wider margins and reduced re-excision rates. However, to date, there is a lack of data demonstrating significant reduction in local recurrence and overall survival when compared with less extensive procedures. In this review, "minimalist" procedures are described where strict oncologic criteria of clear margins are fulfilled and acceptable cosmesis are simultaneously achieved. These techniques offer less tissue loss, less extensive parenchymal mobilisation and shorter operating times without compromising margin status and aesthetics. They involve the combination of innovative incision designs and certain parenchymal resection patterns. Incision designs include the boomerang, golf-tee, anchor and arrowhead incisions which have been previously described but not widely used. Parenchymal resection patterns follow the "sick lobe hypothesis". These techniques, termed "reductionist", or "minimalist" comprising approaches where breast conserving surgery is condensed to its irreducible elements, offer alternatives which align with contemporary objectives of surgery where optimal survival outcomes are achieved through individualised procedures resulting in reduced iatrogenic impact. This logically allows scope for de-escalation of surgical therapy for breast cancer.

To analyze the release kinetics and the clinical and histological effects of UV-cross-linked hyaluronic acid as a release-system for the transforming growth factor β-2 antagonist tranilast with anti-phlogistic properties on intraocular pressure after trabeculectomy in an aggressive scarring animal model. Hyaluronate acid was UV-cross linked and loaded with tranilast. The release of tranilast into a buffered salt solution was assessed spectrophotometrically. Glaucoma filtration surgery, similar to that performed in clinical practice, was performed on chinchilla rabbits. The rabbits were divided in 3 groups. (Group A: trabeculectomy alone, group B: trabeculectomy with a cross-linked hyaluronic acid gel preparation and group C: trabeculectomy with cross-linked hyaluronic gel preparation mixed with tranilast). Antifibrotic efficacy was established by clinical response and histologic examination. The cross-linked gels released tranilast for up to 26 h. The release plotted as a function of the square root of time was consistent with a largely diffusion-controlled release system. Both the gel preparation alone and the gel preparation mixed with tranilast were well tolerated in vivo. No adverse effects such as inflammation, corneal toxicity or blurring of the optical media were observed. The intraocular pressure reached preoperative levels within 9 days after surgery in control animals and group B, but remained significantly reduced (p = 0.00016) in the group with tranilast until day 22. The data of this pilot study suggest that the intraoperative application of UV-crossed linked hyaluronic acid used as a slow release system for tranilast may improve the surgical outcome of glaucoma filtration surgery.

Hip Resurfacing Using Highly Cross-linked Polyethylene: Prospective Study Results at 8.5 Years.

PubMed

Pritchett, James W

2016-10-01

Hip resurfacing is an option to consider when treating younger, more active patients. Advantages over total hip arthroplasty include a more normal gait and a lower incidence of thigh pain. In this prospective study, 190 hip resurfacing procedures (164 participants) were performed using a cobalt-chromium femoral component and a cementless acetabular cup with a 3.8-mm highly cross-linked polyethylene acetabular liner. The mean follow-up was 8.5 (range, 7-10) years. Two participants were lost to follow-up and 2 died. One participant underwent successful revision surgery for acetabular loosening. Four participants underwent successful revision to a total hip arthroplasty because of femoral neck fracture (2), femoral loosening, or infection. The Kaplan-Meier survivorship was 97%. Acetabular bone conservation was assessed using computed tomography by measuring the medial acetabular wall. The mean thickness was 9 mm. Femoral bone was well preserved with a mean head:neck ratio of 1.37. There were 4 (2%) osteolytic defects up to 0.9 cm(3) on computed tomography and no instances of impending polyethylene wear-through. Seven polyethylene retrievals had a measured wear rate of 0.05 mm/y. Hip resurfacing using a highly cross-linked polyethylene acetabular component is a reliable procedure. Both femoral and acetabular bones are reasonably preserved compared with prior resurfacing methods. The low incidence of osteolysis and the low rate of wear found on retrievals suggest that many years of use in highly active patients is possible. Copyright © 2016 Elsevier Inc. All rights reserved.

To assess the outcome of aggressive but conservative laparoscopic surgery in the treatment of severe endometriosis involving the rectum. Retrospective study (Canadian Task Force classification III). Endosurgery unit of a tertiary referral center. One hundred sixty-nine women. Laparoscopy or laparotomy. The procedure was completed successfully laparoscopically in 145 (86%) and by laparotomy in 24 women (14%). The rate of preoperative symptoms was higher in 25 women who underwent bowel resection compared with those who had other bowel surgery. In addition to bowel surgery, excision of uterosacral ligaments, adhesiolysis, excision of endometrioma, and oophorectomy were the four most commonly performed procedures. At 35-month follow-up 61 patients (36%) required further surgery for pain. The average time between primary and repeat surgery was 16 months. This second operation was performed by laparoscopy in over three-fourths of the women. Overall recurrent endometriosis was found in 26 patients (15%). Overall morbidity associated with all surgery was 12.4%. Surgery for endometriosis of the cul-de-sac and bowel involves some of the most difficult dissections encountered, but it can be accomplished successfully with the low postoperative morbidity typical of laparoscopy.

A survey of healthcare industry representatives' participation in surgery: some new ethical concerns.

To provide preliminary evidence of the types and amount of involvement by healthcare industry representatives (HCIRs) in surgery, as well as the ethical concerns of those representatives. A link to an anonymous, web-based survey was posted on several medical device boards of the website http://www. cafepharma.com. Additionally, members of two different medical device groups on LinkedIn were asked to participate. Respondents were self-identified HCIRs in the fields of orthopedics, cardiology, endoscopic devices, lasers, general surgery, ophthalmic surgery, oral surgery, anesthesia products, and urologic surgery. A total of 43 HCIRs replied to the survey over a period of one year: 35 men and eight women. Respondents reported attending an average of 184 surgeries in the prior year and had an average of 17 years as an HCIR and six years with their current employer. Of the respondents, 21 percent (nine of 43) had direct physical contact with a surgical team or patient during a surgery, and 88 percent (38 of 43) provided verbal instruction to a surgical team during a surgery. Additionally, 37 percent (16 of 43) had participated in a surgery in which they felt that their involvement was excessive, and 40 percent (17 of 43) had attended a surgery in which they questioned the competence of the surgeon. HCIRs play a significant role in surgery. Involvement that exceeds their defined role, however, can raise serious ethical and legal questions for surgeons and surgical teams. Surgical teams may at times be substituting the knowledge of the HCIR for their own competence with a medical device or instrument. In some cases, contact with the surgical team or patient may violate the guidelines not only of hospitals and medical device companies, but the law as well. Further study is required to determine if the patients involved have any knowledge or understanding of the role that an HCIR played in their surgery. Copyright 2014 The Journal of Clinical Ethics.

De Vos, Maarten J; Wagener, Marc L; Hendriks, Jan C M; Eygendaal, Denise; Verdonschot, Nico

2013-09-01

Presently, 2 types of elbow prostheses are used: unlinked and linked. The Latitude total elbow prosthesis allows the surgeon to decide during the implantation whether the prosthesis is placed unlinked or linked, and whether the native radial head is retained, resected, or replaced. The purpose of this study is to assess and to compare the varus and valgus laxity of the unlinked and linked version of the latitude total elbow prosthesis with: (1) the native radial head preserved, (2) the native radial head excised, and (3) the native radial head replaced by a radial head component. Biomechanical testing was performed on 14 fresh-frozen upper limb specimens. Linking the prosthesis predominantly influences the valgus laxity of the elbow. Linking the Latitude total elbow prosthesis results in increased valgus stability. In the linked version of the total elbow prosthesis, the radial head only plays a small part in both valgus and varus stability. An unlinked situation is not advised in absence of a native radial head or in case of inability to replace the radial head. Copyright © 2013 Journal of Shoulder and Elbow Surgery Board of Trustees.

To determine whether dizziness and falls rates change due to routine cataract surgery and to determine the influence of spectacle type and refractive factors. Self-reported dizziness and falls were determined in 287 patients (mean age of 76.5 ± 6.3 years, 55% females) before and after routine cataract surgery for the first (81, 28%), second (109, 38%) and both eyes (97, 34%). Dizziness was determined using the short-form of the Dizziness Handicap Inventory. Six-month falls rates were determined using self-reported retrospective data. The number of patients with dizziness reduced significantly after cataract surgery (52% vs 38%; χ(2) = 19.14(,) p < 0.001), but the reduction in the number of patients who fell in the 6-months post surgery was not significant (23% vs 20%; χ(2) = 0.87, p = 0.35). Dizziness improved after first eye surgery (49% vs 33%, p = 0.01) and surgery on both eyes (58% vs 35%, p < 0.001), but not after second eye surgery (52% vs 45%, p = 0.68). Multivariate logistic regression analyses found significant links between post-operative falls and change in spectacle type (increased risk if switched into multifocal spectacles). Post-operative dizziness was associated with changes in best eye visual acuity and changes in oblique astigmatic correction. Dizziness is significantly reduced by first (or both) eye cataract surgery and this is linked with improvements in best eye visual acuity, although changes in oblique astigmatic correction increased dizziness. The lack of improvement in falls rate may be associated with switching into multifocal spectacle wear after surgery. © 2015 The Authors Ophthalmic and Physiological Optics published by John Wiley & Sons Ltd on behalf of College of Optometrists.

Although recent studies have improved understanding of quality of life (QOL) outcomes of breast conserving surgery, few have used longitudinal data for more than two time points, and few have examined predictors of QOL over two years. Additionally, the longitudinal data analyses in such studies rarely apply the appropriate statistical methodology to control for censoring and inter-correlations arising from repeated measures obtained from the same patient pool. This study evaluated an internet-based system for measuring longitudinal changes in QOL and developed a cloud-based system for managing patients after breast conserving surgery. This prospective study analyzed 657 breast cancer patients treated at three tertiary academic hospitals. Related hospital personnel such as surgeons and other healthcare professionals were also interviewed to determine the requirements for an effective cloud-based system for surveying QOL in breast cancer patients. All patients completed the SF-36, Quality of Life Questionnaire (QLQ-C30) and its supplementary breast cancer measure (QLQ-BR23) at baseline, 6 months, 1 year, and 2 years postoperatively. The 95% confidence intervals for differences in responsiveness estimates were derived by bootstrap estimation. Scores derived by these instruments were interpreted by generalized estimating equation before and after surgery. All breast cancer surgery patients had significantly improved QLQ-C30 and QLQ-BR23 subscale scores throughout the 2-year follow-up period (p<0.05). During the study period, QOL generally had a negative association with advanced age, high Charlson comorbidity index score, tumor stage III or IV, previous chemotherapy, and long post-operative LOS. Conversely, QOL was positively associated with previous radiotherapy and hormone therapy. Additionally, patients with high scores for preoperative QOL tended to have high scores for QLQ-C30, QLQ-BR23 and SF-36 subscales. Based on the results of usability testing, the five constructs were rated on a Likert scale from 1-7 as follows: system usefulness (5.6±1.8), ease of use (5.6±1.5), information quality (5.4±1.4), interface quality (5.5±1.4), and overall satisfaction (5.5±1.6). The current trend in clinical medicine is applying therapies and interventions that improve QOL. Therefore, a potentially vast amount of internet-based QOL data is available for use in defining patient populations that may benefit from therapeutic intervention. Additionally, before undergoing breast conserving surgery, patients should be advised that their postoperative QOL depends not only on the success of the surgery, but also on their preoperative functional status.

The alpine desert of Qinghai-Tibet Plateau (QTP) provides the largest habitats for those endangered ungulates (e.g., Tibetan antelope, Tibetan Kiang and wild yak) on the earth. However, human disturbance especially infrastructure constructions (e.g., railway & highway) has increasingly fragmented the habitats of those endangered ungulates by disturbing and interrupting their ecological corridors for their seasonal migration. Aiming at identifying the potential ecological corridors for Tibetan antelope, a GIS-based model-Linkage Mapper was used to model and detect the potential ecological corridors of Tibetan antelope based on the principle of least cost path. Three categories of ecological corridors, i. e., closed (inside reserves), linking (linking the reserves) and open (starting from reserve but ending outside) corridors were distinguished by their spatial interactions with existing major national nature reserves (i.e., Altun, Kekexili and Qiangtang NNRs) in the alpine desert of QTP, and their spatial patterns, conservation status associated with human disturbance were also examined. Although our research indicated a general ecological integration of both habitats and ecological corridors in the alpine desert ecosystem, increasing human disturbance should not be ignored, which particularly partially undermined the functioning of those ecological corridors linking the nature reserves. Considering disadvantages of prevailing separate administrative structure of nature reserve on the effective conservation of ecological corridors for those endangered ungulates, a coordinative conservation network among these major national nature reserves should be established to ensure the unified trans-boundary conservation efforts and to enhance its overall conservation efficacy by sharing information, knowledge and optimizing conservation resources.

We report a case of conservative treatment of ectopic pregnancy in a 27 years old patient, previously treated for ovarian cancer. Two years before she had surgery because of tumour in the left ovary. Ovarian cancer in stage la according to FIGO was confirmed. Considering the patient s young age, future reproductive plans and the early stage of cancer, the patient qualified for conservative treatment. Left adnexectomy with consequent chemotherapy (6 courses) was performed. Two years later on the ground of clinical symptoms, gynaecologic examination, sonography and changes in HCG serum concentration, ectopic pregnancy was recognised in the right tube. We applied conservative management with intramuscularly administrated Methotrexate. The patient, in good condition, was discharged from hospital on day 12 after injection of Methotrexate.

Social network analysis (SNA) is based on a conceptual network representation of social interactions and is an invaluable tool for conservation professionals to increase collaboration, improve information flow, and increase efficiency. We present two approaches to constructing internet-based social networks, and use an existing traditional (survey-based) case study to illustrate in a familiar context the deviations in methods and results. Internet-based approaches to SNA offer a means to overcome institutional hurdles to conducting survey-based SNA, provide unique insight into an institution's web presences, allow for easy snowballing (iterative process that incorporates new nodes in the network), and afford monitoring of social networks through time. The internet-based approaches differ in link definition: hyperlink is based on links on a website that redirect to a different website and relatedness links are based on a Google's "relatedness" operator that identifies pages "similar" to a URL. All networks were initiated with the same start nodes [members of a conservation alliance for the Calumet region around Chicago (n = 130)], but the resulting networks vary drastically from one another. Interpretation of the resulting networks is highly contingent upon how the links were defined.

Glaucoma is one of the most common causes of blindness worldwide, and its prevalence is increasing. The aim of the present review is to describe the current medical and surgical treatment trends in the management of open-angle glaucoma. There has been an increase in the availability of glaucoma medications and the use of laser trabeculoplasty over the past decade, with a subsequent decrease in invasive incisional surgery. In addition, a new class of glaucoma procedures, termed microinvasive glaucoma surgery, has emerged, which aims to fill the gap between conservative medical management and more invasive surgery.

Recent progress in heart valve surgery: innovation or evolution?

Lausberg, H; Schäfers, H J

2004-08-01

Although heart valve surgery continues to evolve in a dynamic fashion, there is still no optimal solution for all patients. Minimally invasive surgery currently receives considerable attention but its value still needs to be determined. Progress has been made in valve repair, which now allows reconstruction in most patients with mitral valve disease. Reconstruction of the aortic valve is now also possible with results that are now comparable to those of mitral repair. In the future a wider application of repair procedures and further improvements of biologic valves can be anticipated not only to influence long-term results, but also the decision making process for conservative or surgical treatment.

Successful glycemic control reduces morbidity and mortality in cardiac surgery patients. Protocols that include insulin infusions are commonly followed to achieve target blood glucose levels. Insulin resistance has been reported and linked to low serum phosphate levels in animal models and studies in diabetic outpatients, but not in postoperative patients. The following case series is a retrospective observational review of 8 cardiac surgery patients who developed insulin resistance early after surgery; this resistance was reversed by correcting serum hypophosphatemia. We discuss the multiple underlying mechanisms causing hypophosphatemia.

2009-06-01

Ankle instability in the athlete is a common problem that is routinely treated non-operatively, with a 90% success rate. With proprioceptive training, preventive equipment (bracing/taping), and closed kinetic chain strengthening, surgery for ankle instability is uncommon. Nonetheless, some athletes present with recurrent ankle instability that, despite work-up and conservative treatment, requires surgical correction. The use of a primary ligament repair (Brostrom procedure) versus augmented (anatomic) reconstructions is discussed in detail in this article.

ε-Aminocaproic acid and clinical value in cardiac anesthesia.

Raghunathan, Karthik; Connelly, Neil Roy; Kanter, Gary J

2011-02-01

The primary aim was to compare the "clinical value" of tranexamic acid (TXA) with ε-aminocaproic acid (EACA) when used for blood conservation during high-risk cardiac surgery. Data previously reported by the Blood Conservation Using Antifibrinolytics in a Randomized Trial (BART) study investigators were reanalyzed independently after appropriate statistical adjustment. The authors compared TXA with EACA for important primary and secondary outcomes and applied the "clinical value" equation to this comparison. BART, the largest blinded multicenter study on this topic to date, compared all 3 commonly used antifibrinolytics head-to-head in a randomized dose-equivalent fashion during high-risk cardiac surgery. Comparisons of TXA with EACA with application of the clinical value equation was not performed specifically by the BART investigators. One thousand five hundred fifty patients enrolled in 2 of the 3 arms of the BART study were included in the analysis (TXA, n= 770 and EACA, n = 780, with data reported by the investigators in the New England Journal of Medicine). The major finding was that there were no significant differences in overall safety and clinically important efficacy between TXA and EACA. Considering the substantial difference in costs and with the increasing volume of high-risk cardiac surgery, EACA has increased "clinical value" when compared with TXA. EACA should be the antifibrinolytic medication of choice for high-risk cardiac surgery. Copyright © 2011 Elsevier Inc. All rights reserved.

Breast-conserving surgery is equivalent to total mastectomy in the treatment of breast cancer. The Southern part of the United States has a low rate of breast conservation. We surveyed 300 women: 100 hospital personnel, 100 cancer clinic patients, and 100 non-cancer clinic patients. The women were asked about their attitudes toward breast cancer, surgery preferences, and factors that might influence their decisions. One hundred eighty-nine chose mastectomy as the best operation, 106 women chose lumpectomy, and five women were undecided. There was no difference in mean age, racial distribution, education level, income level, percentage of women who considered themselves Southern women, concerns about breast cancer, recent mammograms, previous breast surgery, previous breast cancer treatment, or acquaintances with breast cancer between the mastectomy and the lumpectomy groups. Women interested in saving the breast were more likely to pick lumpectomy (35 vs. 84%, p = 0.001). A fear of cancer recurrence played a role in the decision (88 vs. 40%, p = 0.001). Fear of radiation therapy (76 vs. 57%, p = 0.002) and of the side effects (80 vs. 63%, p = 0.005) was a significant factor. The choice of surgery for breast cancer is an individual process between a woman and her surgeon. Attitudes and fears regarding cancer recurrence and radiation therapy may make women select mastectomy over lumpectomy.

PURPOSE OF STUDY Osteochondritis dissecans (OCHD) is an increasingly diagnosed disease among adolescent patients. It is a condition affecting subchondral bone and the lining cartilage. If left untreated, it can cause destruction of cartilage of the affected joint leading to early development of arthrosis. Mostly affected joints are knees and ankles, but affected elbow and other joints have been described too. The purpose of our study is to present the patients diagnosed and treated surgically at our clinic with arthroscopic drilling in the period 2010-2015, and subsequently the clinical findings obtained at follow-up checks after the surgery. MATERIAL AND METHODS Between 2010 and 2015, a total of 34 patients (36 joints) underwent surgical treatment at our clinic. Their age ranged from 6 to 19 years at the time of surgery, 17 girls and 17 boys underwent the surgery. All the patients were treated with transarticular antegrade arthroscopic drilling. Each patient was diagnosed based on the clinical finding, radiographs, or MRI. The patients were followed after 6 weeks, thereafter 3, 6, and 12 months after the surgery. Each patient was evaluated based on the clinical findings (presence of swelling, range of motion, and pain according to VAS), and radiographs. RESULTS The preoperative VAS was 2.9 and dropped down to 1.5 at the first follow-up visit. None of the patients complained of pain at 1-year follow-up. 34 (out of 36) patients suffered joint swelling preoperatively, 6 weeks after the surgery only 9 patients presented with ongoing swelling, at 1-year follow-up no patient reported this problem. The X-ray findings showed regression in 35 of 36 patients one year after the surgery. One female patient underwent redo surgery because of an ongoing restriction of movement and X-ray finding persistence. DISCUSSION Majority of patients with OCHD can be treated conservatively. Physical activity modification and temporary immobilization are commonly used treatment methods of this condition. If conservative treatment is unsuccessful, arthroscopy should be considered. Stable lesions have a high chance of spontaneous healing without surgery. There is a variety of arthroscopic treatment methods. Mostly transarticular transchondral drilling is used to treat this condition. CONCLUSION Treatment of OCHD with arthroscopic drilling shows promising results in our cohort of patients. We recommend to use arthroscopic drilling in patients in stage I to III according to X-ray when 3 months of conservative treatment do not improve the clinical symptoms, swelling and restriction of movement. Antegrade drilling is the most frequently used treatment method in OCHD at our clinic, we consider this technique a simple and effective, with short surgical time needed. Key words: osteochondritis dissecans, treatment, arthroscopy, drilling.

To analyse the natural history of extra-abdominal wall desmoid-type fibromatosis (DF) and compare outcome in patients who underwent initial surgery with those who did not. All consecutive patients affected by primary sporadic extra-abdominal wall DF observed between January 1992 and December 2012 were included. Patients were divided into surgical (SG) or non-surgical groups (NSG) according to initial treatment. Relapse free survival was calculated for SG, and crude cumulative incidence (CCI) of switching to surgery or other treatments for NSG. 216 patients were identified, 94 in SG (43%), 122 in NSG (57%). A shift towards a more systematic use of a conservative approach (78% of all comers) was observed in the latter years (2006-2012), although a small proportion of patients (28%) had been offered the conservative strategy even in the early period (1992-2005). Median follow-up (FU) was 49 mo. (interquartile (IQ), 20-89 mo.), 76 months for SG and 39 months for NSG. 5-year relapse-free survival (RFS) for SG was 80% (95% confidence interval (CI), 72-89%). For the NSG, 5-year CCI of switching to surgery was 5% (95% CI: 1.7%, 14%), and 51% to other treatments (95% CI: 41%, 65%). 27 (20%) NSG patients underwent spontaneous regression. A non-surgical approach to extra-abdominal wall DF allowed surgery to be avoided in the majority of patients. This approach can be safely proposed and surgery offered as an option in selected cases.

Breast cancer (BC) and/or its treatments may affect sexual functioning based on physiological and psychosocial mechanisms. The aim of this study was to prospectively investigate sexual adjustment of BC patients during a follow-up period of one year after mastectomy (ME) or breast conserving therapy (BCT). In this prospective controlled study, women with BC and an age-matched control group of healthy women completed the Beck Depression Inventory Scale, World Health Organization 5 Well-being scale, Body Image Scale, EORTC QLQ questionnaire, Dyadic Adjustment Scale, Short Sexual Functioning Scale and Specific Sexual Problems Questionnaire to assess various aspects of sexual and psychosocial functioning before surgery, six months and one year after surgical treatment. In total, 149 women with BC and 149 age-matched healthy controls completed the survey. Compared to the situation before surgery, significantly more BCT women reported problems with sexual arousal six months after surgery and significantly more women of the ME group reported problems with sexual desire, arousal and the ability to achieve an orgasm six months and one year after surgery. While in comparison with healthy controls, no significant differences in sexual functioning were found after BCT surgery, significantly more women who underwent ME reported problems with sexual desire, arousal, the ability to achieve an orgasm and intensity of the orgasm. Although little differences were seen in sexual functioning in the BCT group during prospective analyses and in comparison with healthy controls, analyses revealed that women who underwent a ME were at risk for post-operative sexual dysfunctions.

2016-10-01

The history of pediatric plastic surgery is linked to that of paediatrics. Until the early 19th century, there was no children's hospital. Only some operations were performed before the discovery of anesthesia, aseptic and antisepsis: cleft lip repair, amputation for polydactyly. Many operations were described in the 19th century for cleft lip and palate repair, hypospadias, syndactylies. The first operation for protruding ears was performed in 1881. Pediatric plastic surgery is diversified in the 2nd half of the 20th century: cleft lip and palate, burns, craniofacial surgery, hand surgery become separate parts of the speciality.

Pain, function, adverse events. MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), Google Scholar and Open Grey up to August 2016. For effects, randomised clinical trials (RCTs) comparing arthroscopic surgery with a conservative management strategy (including sham surgery) in patients with degenerative knee disease. For complications, RCTs and observational studies. Two reviewers independently extracted data and assessed risk of bias for patient-important outcomes. A parallel guideline committee ( BMJ Rapid Recommendations) provided input on the design and interpretation of the systematic review, including selection of patient-important outcomes. We used the GRADE approach to rate the certainty (quality) of the evidence. We included 13 RCTs and 12 observational studies. With respect to pain, the review identified high-certainty evidence that knee arthroscopy results in a very small reduction in pain up to 3 months (mean difference =5.4 on a 100-point scale, 95% CI 2.0 to 8.8) and very small or no pain reduction up to 2 years (mean difference =3.1, 95% CI -0.2 to 6.4) when compared with conservative management. With respect to function, the review identified moderate-certainty evidence that knee arthroscopy results in a very small improvement in the short term (mean difference =4.9 on a 100-point scale, 95% CI 1.5 to 8.4) and very small or no improved function up to 2 years (mean difference =3.2, 95% CI -0.5 to 6.8). Alternative presentations of magnitude of effect, and associated sensitivity analyses, were consistent with the findings of the primary analysis. Low-quality evidence suggested a very low probability of serious complications after knee arthroscopy. Over the long term, patients who undergo knee arthroscopy versus those who receive conservative management strategies do not have important benefits in pain or function. PROSPERO CRD42016046242.

Flash scanning the CO2 laser: a revival of the CO2 laser in plastic surgery

NASA Astrophysics Data System (ADS)

Lach, Elliot

1994-09-01

The CO2 laser has broad clinical application yet also presents a number of practical disadvantages. These drawbacks have limited the success and utilization of this laser in plastic surgery. Flashscanner technology has recently been used for char-free CO2 laser surgery of the oropharynx, the external female genital tract, and perirectal mucosa. A commercially available optomechanical flashscanner unit `Swiftlase,' was adapted to a CO2 laser and used for treatment in numerous plastic surgical applications. Conditions and situations that were treated in this study included generalized neurofibromatosis, tuberous sclerosis, rhinophyma, viral warts, breast reconstruction, and deepithelialization prior to microsurgery or local flap transfer and/or skin graft placement. There were no significant wound healing complications. Some patients previously sustained undue scarring from conventional CO2 laser surgery. Conservative, primarily ablative CO2 laser surgery with the Swiftlase has usefulness for treatment of patients in plastic surgery including those that were previously unsuccessfully treated.

Juvenile X linked retinoschisis (XLRS) is a congenital X linked recessive retinal disorder characterised by cystic maculopathy and peripheral schisis. This study presents the case of an 8-month-old boy with a documented positive family history of XLRS, with a large retinoschisis cavity affecting the macula, first in the left eye and 1 year later in the right eye. The patient underwent pars plana vitrectomy in both eyes using 23-G instruments, posterior hyaloid dissection, a small retinotomy, fluid drainage with a 42-G cannula, infrared diode laser and silicone oil as internal tamponade. The anatomical and functional outcomes at 3 years following the first surgery are described. To the authors' knowledge, there is no previously reported experience with this technique in patients with XLRS.

Groove pancreatitis (GP) is a focal form of chronic pancreatitis affecting the paraduodenal groove area, for which consensus on diagnosis and management is lacking. We performed a systematic review of the literature to determine patient characteristics and imaging features of GP and to evaluate clinical outcomes after treatment. Eight studies were included reporting on 335 GP patients with a median age of 47 years (range, 34 to 64 y), with 90% male, 87% smokers, and 87% alcohol consumption, and 47 months (range, 15 to 122 mo) of follow-up. Most patients presented with abdominal pain (91%) and/or weight loss (78%). Imaging frequently showed cystic lesions (91%) and duodenal stenosis (60%).Final treatment was conservative (eg, pain medication) in 29% of patients. Endoscopic treatment (eg, pseudocyst drainage) was applied in 19% of patients-34% of these patients were subsequently referred for surgery. Overall, 59% of patients were treated surgically (eg, pancreatoduodenectomy). Complete symptom relief was observed in 50% of patients who were treated conservatively, 57% who underwent endoscopic treatment, and 79% who underwent surgery. GP is associated with male gender, smoking, and alcohol consumption. The vast majority of patients presents with abdominal pain and with cystic lesions on imaging. Although surgical treatment seems to be the most effective, both conservative and endoscopic treatment are successful in about half of patients. A stepwise treatment algorithm starting with the least invasive treatment options seems advisable.

Diverticular disease of the colon occurs quite frequently in developed countries, and its prevalence has recently increased in Japan. The appearance of diverticulosis increases with age, although mostly remaining asymptomatic. Approximately 20% of cases require treatment. As the Western lifestyle and number of elderly people increase, the need for medical treatment also increases. Computed tomography (CT) is the gold standard for diagnosing diverticulitis. Complicated diverticulitis is classified by the size and range of abscess formation and the severity of the peritonitis. Each case should be classified based on clinical and computed tomography (CT) findings and then treated appropriately. Most patients with uncomplicated diverticulitis (stages 0-Ia) can be treated conservatively. Diverticulitis with a localized abscess (stages Ib-II) is generally resolved with conservative treatment. If the abscess is larger or conservative treatment fails, however, percutaneous drainage or surgery should be considered. Operative treatment is considered standard therapy for severe diverticulitis with perforation and generalized peritonitis (stages III-IV). Colonic diverticulitis treated conservatively frequently recurs. Elective surgery after recovery should be considered carefully and decisions made on a case-by-case basis. Because cases of colonic diverticulitis will undoubtedly increase in Japan, it is likely that we will be confronted with increasing numbers of treatment decisions. We therefore need to have a systematic strategy for treating the various stages of colonic diverticulitis appropriately. We herein review the management of complicated diverticulitis.

Quality of life and cosmethic appearance have gained importance as outcomes in AIS treatment. Improving aesthetic appearance and quality of life are defined as the primary aims of scoliosis treatment by health professionals. Studies that assess and compare the different treatment results in the field of quality of life and cosmethics are some what limited. A cross-sectional study was designed to compare quality of life and deformity perception in patients with adolescent idiopathic scoliosis (AIS) received conservative (exercise or exercise + brace) or surgical treatment. A total of 68 (58 females) patients aged 10-18 years with AIS received conservative (exercise or exercise+brace) or surgical treatment were invited to participate in the study. Quality of life (Scoliosis Research Society-23 (SRS-23)) and perception of deformity (Walter Reed Visual Assessment (WRVAS)) were assessed. Conservatively treated patients had significantly superior scores in function domain of SRS-23 than surgically treated patients (exercise/surgery, exercise+brace/surgery; p= 0.009, 0.004). Otherwise, surgically treated patients had significantly superior scores in self-image (p= 0.000, 0.000), and satisfaction with management (p= 0.001, 0.006) domains of SRS-23, and WRVAS (p= 0.000, 0.000) than conservative groups. In addition to radiographic assessments, quality of life, aesthetic perception, functionality, satisfaction with management, psycho-social status should carefully be taken into consideration by health professionals in the teratment of AIS.

Sports hernias: a systematic literature review.

Caudill, P; Nyland, J; Smith, C; Yerasimides, J; Lach, J

2008-12-01

This review summarises the existing knowledge about pathogenesis, differential diagnosis, conservative treatment, surgery and post-surgical rehabilitation of sports hernias. Sports hernias occur more often in men, usually during athletic activities that involve cutting, pivoting, kicking and sharp turns, such as those that occur during soccer, ice hockey or football. Sports hernias generally present an insidious onset, but with focused questioning a specific inciting incident may be identified. The likely causative factor is posterior inguinal wall weakening from excessive or high repetition shear forces applied through the pelvic attachments of poorly balanced hip adductor and abdominal muscle activation. There is currently no consensus as to what specifically constitutes this diagnosis. As it can be difficult to make a definitive diagnosis based on conventional physical examination, other methods, such as MRI and diagnostic ultrasonography are often used, primarily to exclude other conditions. Surgery seems to be more effective than conservative treatment, and laparoscopic techniques generally enable a quicker recovery time than open repair. However, in addition to better descriptions of surgical anatomy and procedures and conservative and post-surgical rehabilitation, well-designed research studies are needed, which include more detailed serial patient outcome measurements in addition to basing success solely on return to sports activity timing. Only with this information will we better understand sports hernia pathogenesis, verify superior surgical approaches, develop evidence-based screening and prevention strategies, and more effectively direct both conservative and post-surgical rehabilitation.

An ulcer categorized as Fontaine's stage IV represents a chronic wound, risk factor of arteriosclerosis, and co-morbidities which disturb wound healing. Our objective was to analyze wound healing and to assess potential factors affecting the healing process. 199 patients were included in this 5-year study. The significance levels were determined by chi-squared and log-rank tests. The calculation of patency rate followed the Kaplan-Meier method. Mean age and co-morbidities did not differ from those in current epidemiological studies. Of the patients with ulcer latency of more than 13 weeks (up to one year), 40% required vascular surgery. Vascular surgery was not possible for 53 patients and they were treated conservatively. The amputation rate in the conservatively treated group was 37%, whereas in the revascularizated group it was only 16%. Ulcers in patients with revascularization healed in 92% of cases after 24 weeks. In contrast, we found a healing rate of only 40% in the conservatively treated group (p<0.001). Revascularization appeared more often in diabetic patients (n=110; p<0.01) and the wound size and number of infections were elevated (p=0.03). Among those treated conservatively, wound healing was decelerated (p=0.01/0.02; chi(2) test). The success of revascularization, presence of diabetes mellitus, and wound treatment proved to be prognostic factors for wound healing in arterial ulcers.

The objectives of this consensus conference were to evaluate the evidence for the efficacy and safety of perioperative drugs, technologies, and techniques in reducing allogeneic blood transfusion for adults undergoing cardiac surgery and to develop evidence-based recommendations for comprehensive perioperative blood management in cardiac surgery, with emphasis on minimally invasive cardiac surgery. The consensus panel short-listed the potential topics for review from a comprehensive list of potential drugs, devices, technologies, and techniques. The process of short-listing was based on the need to prioritize and focus on the areas of highest importance to surgeons, anesthesiologists, perfusionists, hematologists, and allied health care involved in the management of patients who undergo cardiac surgery whether through the conventional or minimally invasive approach. MEDLINE, Cochrane Library, and Embase databases were searched from their date of inception to May 2011, and supplemental hand searches were also performed. Detailed methodology and search strategies are outlined in each of the subsequently published systematic reviews. In general, all relevant synonyms for drugs (antifibrinolytic, aprotinin, [Latin Small Letter Open E]-aminocaproic acid, tranexamic acid [TA], desmopressin, anticoagulants, heparin, antiplatelets, anti-Xa agents, adenosine diphosphate inhibitors, acetylsalicylic acid [ASA], factor VIIa [FVIIa]), technologies (cell salvage, miniaturized cardiopulmonary bypass (CPB) circuits, biocompatible circuits, ultrafiltration), and techniques (transfusion thresholds, minimally invasive cardiac or aortic surgery) were searched and combined with terms for blood, red blood cells, fresh-frozen plasma, platelets, transfusion, and allogeneic exposure. The American Heart Association/American College of Cardiology system was used to label the level of evidence and class of each recommendation. Database search identified more than 6900 articles, with 4423 full-text randomized controlled trials assessed for eligibility, and the final 125 systematic reviews and meta-analyses were used in the consensus conference. The results of the consensus conference, including the evidence-based statements and the recommendations, are outlined in the text, with references given for the relevant evidence that formed the basis for the statements and recommendations. RECOMMENDATIONS FOR ANTIFIBRINOLYTICS: The lysine analogs ?-aminocaproic acid (Amicar) and tranexamic acid (TA) reduce exposure to allogeneic blood inpatients undergoing on-pump cardiac surgery. These agents are recommended to be used routinely as part of a blood conservation strategy especially in patients at risk of undergoing onpump cardiac surgery (Class I, Level A). It is important not to exceed maximum TA total dosages (50Y100mg/kg) because of potential neurotoxicity in the elderly and open-heart procedures (Class IIb, Level C). Aprotinin is not recommended in adult cardiac surgery until further studies on its safety profile have been performed (Class III, Level A). RECOMMENDATIONS FOR TA IN OFF-PUMP CORONARY ARTERY BYPASS: Tranexamic acid may be recommended as part of a blood conservation strategy in high risk patients undergoing off-pump coronary artery bypass (OPCAB) surgery (Class I, Level A).Tranexamic acid dosing in OPCAB surgery needs further study particularly with regard to possible neurotoxicity such as seizures.In addition, the benefit-risk ratio in OPCAB needs further eludication because of the lower inherent risk for bleeding in this group (Class IIb, Level C). RECOMMENDATIONS FOR DDAVP: DDAVP can be considered for prophylaxis in coronary artery bypass grafting (CABG) surgery, in particular, for patients onASA within 7 days or prolonged CPB more than 140 minutes (Class IIa, Level A). Caution should be used with the DDAVP infusion rate to avoid significant systemic hypotension (Class I, Level A). RECOMMENDATIONS FOR TOPICAL HEMOSTATICS: The routine use of topical antifibrinolytics in cardiac surgery isnot recommended (Class IIa, Level A). Topical fibrin sealants may be considered in clinical situations where conventional approaches of surgical and medical improvement of hemostasis are not effective, that is, with bleeding problems more local than generalized, bearing in mind the blackbox warning of bovine thrombin by the US Food and Drug Administration (Class IIb, Level C).Recommendations for FVIIa:Prophylactic use of FVIIa cannot be recommended because of a significant increase in the risk of thromboembolic events and stroke (Class IIa, Level A).Factor VIIa may be considered in clinical situations where conventional approaches of surgical and pharmacologic hemostasis have failed and uncontrollable hemorrhage poses a high risk of severe and life-threatening outcomes (Class IIb, Level B). RECOMMENDATIONS FOR ERYTHROPOIETIN PLUS IRON: It is reasonable to administer erythropoietin preoperatively to increase red blood cell mass in patients who are anemic or refuse blood products (such as for Jehovah’s Witness faith) or who are likely to have postoperative anemia (Class IIa, Level A). RECOMMENDATIONS FOR ANTIPLATELETS BEFORE CARDIAC SURGERY: Acetylsalicylic acid may be continued until surgery (Class IIa,Level B) For stable elective CABG procedures with no drug-elutingstent, stop clopidogrel 5 days before surgery (Class I, Level A).h For stable elective CABG procedures with drug-eluting stents less than 1 year old, consider continuing clopidogrel or heparin as abridge to surgery (Class IIb, Level C).h Direct-acting P2Y12 receptor antagonists may be a better alternative than clopidogrel in acute coronary syndrome patients undergoing CABG surgery (Class IIa, Level B). RECOMMENDATIONS FOR ANTIPLATELETS AFTER CARDIAC SURGERY: In stable CABG surgery (nonYacute coronary syndrome patients), the routine use of postoperative clopidogrel with ASAis not warranted (Class IIb, Level B). RECOMMENDATIONS FOR ACUTE NORMOVOLEMIC HEMODILUTION: Acute normovolemic hemodilution can be considered in selected patients with adequate preoperative hemoglobin to reduce post-CPB bleeding (Class IIa, Level A).The routine use of acute normovolemic hemodilution is not recommended (Class IIb, Level B). RECOMMENDATIONS FOR RETROGRADE AUTOLOGOUS PRIMING: Retrograde autologous priming is recommended as a blood conservation modality to reduce allogeneic blood transfusion for onpump cardiac surgery (Class I, Level A). RECOMMENDATIONS FOR CELL SALVAGE: Routine use of cell salvage is recommended in operations where an increased blood loss is expected (Class 1, Level A). Cell salvage should be used throughout the entire operation and not merely as a replacement for CPB cardiotomy suction (Class IIa, Level A). BIOCOMPATIBLE CPB CIRCUITS: The routine use of biocompatible coated CPB circuitry may be considered as part of a multimodal blood conservation program. However, the heterogeneity of surface-modified products, anticoagulation management, and CPB technique does not significantly impact surgical blood loss and transfusion needs (Class IIb,Level A). RECOMMENDATIONS FOR MINIATURIZED EXTRACORPOREAL CARDIOPULMONARY CIRCUIT VERSUS CONVENTIONAL EXTRACORPOREAL CARDIOPULMONARY CIRCUIT: Miniaturized extracorporeal cardiopulmonary circuit can be considered as a blood conservation technique to reduce allogeneic blood exposure (Class IIa, Level A); however, issues related to heparinization management and biocompatible coatings remain to be clarified. RECOMMENDATIONS FOR ULTRAFILTRATION (CONTINUOUS OR MODIFIED):h Ultrafiltration may be considered for blood conservation (Class IIb, Level A); however, the impact on clinically relevant outcomes remains unknown. RECOMMENDATIONS FOR PLATELET PLASMAPHERESIS:It is reasonable to recommend platelet plasmapheresis for blood management in cardiac surgery (Class IIa, Level A), although the impact on clinically relevant outcomes remains unknown. RECOMMENDATIONS FOR POINT-OF-CARE MONITORING:The evidence is too premature to recommend point-of-caretechnology for routine use because its use has not been shown to impact clinical outcome (Class IIb, Level A). RECOMMENDATIONS FOR SURGICAL TECHNIQUES FOR OPCAB, MINIMALLY INVASIVE STERNOTOMY FOR AORTIC VALVE SURGERY, MINIMALLY INVASIVE STERNOTOMY FOR MITRAL VALVE SURGERY, AND TRANSCATHETHER AORTIC VALVE IMPLANTATION: Although these minimally invasive procedures are not primarily selected for the purpose of blood management, the reduced allogeneic blood exposure should be considered in the balance of benefits and risks when selecting the appropriate surgery for patients.

We assessed the effect PRP injection on pain and function in patients with lateral epicondylitis where conservative management had failed. We prospectively reviewed 34 patients. The mean follow-up was 26 weeks (range 6-114 weeks). We used the Oxford Elbow Score (OES) and progression to surgery to assess outcomes. 88.2% improved their OES. 8.8% reported symptom progression. One patient had no change. No patients suffered adverse reactions. Two patients underwent an open release procedure. One had the injection repeated. An injection of PRP improves pain and function in patients suffering from LE where conservative management has failed.

Authors presented results in conservative treatment of 54 cases of hip joint with aseptic necrosis of thigh bone. In 22 hips, excluding the typical conservative treatment, EEP injections were given. However, in the remaining 32, different forms of relieve were used. The obtained results in the first group (A) confirm the purpose of enrichment in conservative treatment by adapting intra- articular injections of EEP especially in advanced stages of necrosis (III-IV period of illness) and also in those whose parents did not express their consent on surgery in the early stage of the illness.

Typhoid fever is caused by gram-negative organism Salmonella typhi. The usual presentation is high-grade fever, but complications like gastrointestinal (GI) hemorrhage and perforation are also seen frequently. With the advent of antibiotics, these complications are rarely seen now. We present a case of a young female who was admitted with a diagnosis of typhoid fever presented with a massive GI bleed from ulcers in the terminal ileum and was managed conservatively without endotherapy and surgery.

2015-04-01

Tibialis anterior (TA) tendon rupture is a relatively rare injury that has been documented primarily in case reports. This article is the first large systematic review of the literature on treatment techniques for subcutaneous rupture of TA tendons. Studies for review were identified through a PubMed search. Eligible studies involved cases of closed tendon rupture. Of the 87 cases in the study, 72 were treated with surgery, 15 with conservative measures. Mean age was 63.9 years (surgery group) and 72.4 years (conservative treatment group). Primary repair was used most often for newer injuries, autograft most often for older injuries. Operative repair of subcutaneous TA tendon rupture leads to successful outcomes in many patients. A surgeon who is deciding which operative technique to use for a patient should consider the age of the injury and the findings of intraoperative assessment for tendon necrosis.

The use of models in nursing provides nurses to focus on the role of nursing and its applications rather than medical practice. In addition, it helps patient care to be systematic, purposeful, controlled and effective. One of the commonly used models in nursing is Roy Adaptation Model. According to Roy adaptation model, the aim of nursing is to increase compliance and life expectancy. Roy Adaptation Model evaluates the patient in physiologic mode, self-concept mode, role function mode and interdependence mode aiming to provide holistic care. This article describes the use of Roy Adaptation Model in the care of a patient who has been diagnosed with breast cancer and had breast-conserving surgery. Patient data was evaluated in the four modes of Roy adaptation model (physiologic, self-concept, role function, and interdependence modes) and the nursing process was applied.

Ameloblastic fibroma (AF) is a rare odontogenic tumour of the jaw which usually occurs in the first 2 decades of life. The common clinical manifestation is a slow-growing swelling. We report a case of a 16-year-old male patient presenting with extensive AF of the mandible. He underwent a conservative enucleation. The tumour recurred 2 years after the initial surgery, requiring the second enucleation. The patient has continued to be followed closely and has been disease-free for 4 years. Recent evidence suggests that the recurrent rate of AF is relatively high, and malignant transformation of AF may occur after recurrences or multiple surgeries. A conservative treatment approach with close surveillance is recommended. Anatomical limitations should be taken into account, especially when enucleation of AF in the posterior portion of the jaw is performed. Current surgical pathologic issues of the tumour are also discussed. PMID:19756198

The management of scoliosis in children with cerebral palsy: a review

Gardner, Adrian

2016-01-01

Children who suffer with cerebral palsy (CP) have a significant chance of developing scoliosis during their early years and adolescence. The behavior of this scoliosis is closely associated with the severity of the CP disability and unlike idiopathic scoliosis, it continues to progress beyond skeletal maturity. Conservative measures may slow the progression of the curve, however, surgery remains the only definitive management option. Advances in surgical technique over the last 50 years have provided methods to effectively treat the deformity while also reducing complication rates. The increased risk of surgical complications with these complex patients make decisions about treatment challenging, however with careful pre-operative optimization and post-operative care, surgery can offer a significant improvement in quality of life. This review discusses the development of scoliosis in CP patient, evaluates conservative and surgical treatment options and assesses post-operative outcome. PMID:28097247

The standard treatment for women with early-stage cervical cancer (IA2-IB1) remains radical hysterectomy with pelvic lymphadenectomy. In select patients interested in future fertility, the option of radical trachelectomy with pelvic lymphadenectomy is also considered a viable option. The possibility of less radical surgery may be appropriate not only for patients desiring to preserve fertility but also for all patients with low-risk early-stage cervical cancer. Recently, a number of studies have explored less radical surgical options for early-stage cervical cancer, including simple hysterectomy, simple trachelectomy, and cervical conization with or without sentinel lymph node biopsy and pelvic lymph node dissection. Such options may be available for patients with low-risk early-stage cervical cancer. Criteria that define this low-risk group include: squamous carcinoma, adenocarcinoma, or adenosquamous carcinoma, tumor size <2 cm, stromal invasion <10mm, and no lymph-vascular space invasion. In this report, we provide a review of the existing literature on the conservative management of cervical cancer and describe ongoing multi-institutional trials evaluating the role of conservative surgery in selected patients with early-stage cervical cancer.

Surgical treatment of diseases in the oral cavity and the jaws has been performed since ancient times. However, in the beginning there were mostly simple tooth extractions and treatment of oral infections which could be done. The therapists consisted of a heterogenic group (physicians, barber-surgeons, dental surgeons, smiths, monks etc.). In the beginning of the 20th century great progress was made. Dental surgeons were employed as consultants in hospitals. And when the national dental servIce in Sweden (Folktandvården) was established 1938, departments of oral surgery were built in these hospitals. The department of oral surgery at the University hospital in Linköping started 1947 and is presented in this paper. Dr. Helge Hed, originator of the department, was chief oral surgeon the first 24 years. The surgical activity was gradually increased from 389 operations in 1950 to 1.514 in 1999, and the number of jaw fractures treated in 1948 were 21 and in 1999 73. The treatment panorama has changed during the years. At first the poor dental status of the patients characterized the situation and minor dentoalveolar surgery was usually performed. Later more advanced oral surgery e. g. trauma-surgery, orthognatic surgery and dental implantology has been done - and in addition a lot of scientific research and programmed instructions in oral surgery for dental surgeons and medical students. To sum up, the development of the department of oral surgery at the University hospital in Linköping has been well adjusted to the gradually more demanding treatment and it is representative of the successful development of Swedish oral surgery during the 20th century.

Symptomatic isolated dissection of the superior mesenteric artery (SIDSMA) represents an extremely rare condition. Although various treatments including conservative treatment, endovascular stenting (ES), and surgical repair are currently available, consensus treatment guideline is absent due to scarce of SIDSMA cases. Thus, we present our experience in the treatment of SIDSMA at our single center.Fourteen cases of SIDSMA were treated with conservative treatment, catheter-directed thrombolysis (CDT), endovascular stenting (ES), or surgical repair at our center between January 2008 and January 2014. Demographics, clinical manifestations, coexisting medical conditions, imaging feature, treatments, and follow-up outcome of these patients were retrospectively collected and analyzed.For 13 patients without peritonitis, conservative treatment was given for 4 to 6 days initially. After the first observation cycle, symptoms and signs were alleviated in 8 patients, and conservative treatments were continued. The remaining 5 patients received technically and clinically successful ES (in 4) or CDT (in 1) due to worsening symptoms and signs during conservative treatment. One patient with peritonitis underwent emergency surgery, with the necrotic small intestine resected. However, the abdominal pain was not alleviated 17 days postoperatively, ES was thus performed and symptoms relieved immediately. Two weeks after ES, a new aneurysm and partial thrombosis in the distal part of the stent were found by computed tomography angiography in this patient. No intestinal infarction or mortality developed during hospitalization. Follow-up was accomplished in 11 cases, ranging from 4 to 74 months (23.5 ± 21.3). Except that one complained with mild abdominal pain, the other 10 achieved complete remission. All patients were free from new aneurysmal formation of SMA and all stents remained patent.For SIDSMA without peritonitis, conservative treatment can be provided with reasonable success rate, while ES may serve as an effective alternative once conservative treatment fails. For SIDSMA with peritonitis, open surgery remains the treatment of choice by resection of necrotic intestine and revasculization.

Purpose: To evaluate outcomes of conservative surgery and radiation therapy (RT) treatment in patients with dermatofibrosarcoma protuberans. Methods and Materials: We retrospectively reviewed the medical records of 53 consecutive dermatofibrosarcoma protuberans patients treated with surgery and preoperative or postoperative radiation therapy between 1972 and 2010. Median tumor size was 4 cm (range, 1-25 cm). Seven patients (13%) were treated with preoperative RT (50-50.4 Gy) and 46 patients (87%) with postoperative RT (60-66 Gy). Of the 46 patients receiving postoperative radiation, 3 (7%) had gross disease, 14 (30%) positive margins, 26 (57%) negative margins, and 3 (7%) uncertain margin status. Radiationmore » dose ranged from 50 to 66 Gy (median dose, 60 Gy). Results: At a median follow-up time of 6.5 years (range, 0.5 months-23.5 years), 2 patients (4%) had disease recurrence, and 3 patients (6%) had died. Actuarial overall survival was 98% at both 5 and 10 years. Local control was 98% and 93% at 5 and 10 years, respectively. Disease-free survival was 98% and 93% at 5 and 10 years, respectively. The presence of fibrosarcomatous change was not associated with increased risk of local or distant relapse (P=.43). One of the patients with a local recurrence had gross residual disease at the time of RT and despite RT to 65 Gy developed both an in-field recurrence and a nodal and distant recurrence 3 months after RT. The other patient with local recurrence was found to have in-field recurrence 10 years after initial treatment. Thirteen percent of patients had an RT complication at 5 and 10 years, and 9% had a moderate or severe complication at 5 and 10 years. Conclusions: Dermatofibrosarcoma protuberans is a radioresponsive disease with excellent local control after conservative surgery and radiation therapy. Adjuvant RT should be considered for patients with large or recurrent tumors or when attempts at wide surgical margins would result in significant morbidity.« less

Uniting paradigms of connectivity in marine ecology.

PubMed

Brown, Christopher J; Harborne, Alastair R; Paris, Claire B; Mumby, Peter J

2016-09-01

The connectivity of marine organisms among habitat patches has been dominated by two independent paradigms with distinct conservation strategies. One paradigm is the dispersal of larvae on ocean currents, which suggests networks of marine reserves. The other is the demersal migration of animals from nursery to adult habitats, requiring the conservation of connected ecosystem corridors. Here, we suggest that a common driver, wave exposure, links larval and demersal connectivity across the seascape. To study the effect of linked connectivities on fish abundance at reefs, we parameterize a demographic model for The Bahamas seascape using maps of habitats, empirically forced models of wave exposure and spatially realistic three-dimensional hydrological models of larval dispersal. The integrated empirical-modeling approach enabled us to study linked connectivity on a scale not currently possible by purely empirical studies. We find sheltered environments not only provide greater nursery habitat for juvenile fish but larvae spawned on adjacent reefs have higher retention, thereby creating a synergistic increase in fish abundance. Uniting connectivity paradigms to consider all life stages simultaneously can help explain the evolution of nursery habitat use and simplifies conservation advice: Reserves in sheltered environments have desirable characteristics for biodiversity conservation and can support local fisheries through adult spillover. © 2016 by the Ecological Society of America.

The temporal lobes play a prominent role in declarative memory function, including episodic memory (memory for events) and semantic memory (memory for facts and concepts). Surgical resection for medication-resistant and well-localized temporal lobe epilepsy has good prognosis for seizure freedom, but is linked to memory difficulties in adults, especially when the removal is on the left side. Children may benefit most from surgery, because brain plasticity may facilitate post-surgical reorganization, and seizure cessation may promote cognitive development. However, the long-term impact of this intervention in children is not known. We examined memory function in 53 children (25 males, 28 females) who were evaluated for epilepsy surgery: 42 underwent unilateral temporal lobe resections (25 left, 17 right, mean age at surgery 13.8 years), 11 were treated only pharmacologically. Average follow-up was 9 years (range 5–15). Post-surgical change in visual and verbal episodic memory, and semantic memory at follow-up were examined. Pre- and post-surgical T1-weighted MRI brain scans were analysed to extract hippocampal and resection volumes, and evaluate post-surgical temporal lobe integrity. Language lateralization indices were derived from functional magnetic resonance imaging. There were no significant pre- to postoperative decrements in memory associated with surgery. In contrast, gains in verbal episodic memory were seen after right temporal lobe surgery, and visual episodic memory improved after left temporal lobe surgery, indicating a functional release in the unoperated temporal lobe after seizure reduction or cessation. Pre- to post-surgical change in memory function was not associated with any indices of brain structure derived from MRI. However, better verbal memory at follow-up was linked to greater post-surgical residual hippocampal volumes, most robustly in left surgical participants. Better semantic memory at follow-up was associated with smaller resection volumes and greater temporal pole integrity after left temporal surgery. Results were independent of post-surgical intellectual function and language lateralization. Our findings indicate post-surgical, hemisphere-dependent material-specific improvement in memory functions in the intact temporal lobe. However, outcome was linked to the anatomical integrity of the temporal lobe memory system, indicating that compensatory mechanisms are constrained by the amount of tissue which remains in the operated temporal lobe. Careful tailoring of resections for children undergoing epilepsy surgery may enhance long-term memory outcome. PMID:25392199

Pharmacological treatment of hemorrhoids: a narrative review.

Hemorrhoid disease is the cause of most proctologic complaints and hundreds of medical and surgical therapies have been proposed to relieve symptoms. However, the role and the correct indication of medical treatments are still controversial. Further, the utility of conservative measures are rarely scientifically supported by adequate trials. This narrative review is based on the search and analysis of full papers in English language selected from PubMed in the past 30 years using the following MeSH Editing: hemorrhoids, conservative treatment, medical treatment and hemorrhoids, pregnancy and hemorrhoids, thrombosed hemorrhoids, randomized trials and hemorrhoids, postoperative pain and hemorrhoids. Early stages (I/II degrees) of this disease could be effectively managed conservatively with several approaches as lifestyle changes, fiber supplement, topical ointments and phlebotonic drugs. The more advanced hemorrhoid stages (III/IV degrees) need some type of surgery, but medical therapy is still useful to minimize anal symptoms as a bridge-to-surgery treatment. Further, post-hemorrhoidectomy pain, hemorrhoidal crisis even in pregnancy could benefit from the adjunct of local and systemic medical treatment. This expert opinion, based also on long-lasting clinical practice, also supports the use of medical treatment in symptoms relief in patients with hemorrhoid disease.

Objective To evaluate the cost-effectiveness of bariatric surgery in Italy from a third-party payer perspective over a medium-term (10 years) and a long-term (lifetime) horizon. Methods A state-transition Markov model was developed, in which patients may experience surgery, post-surgery complications, diabetes mellitus type 2, cardiovascular diseases or die. Transition probabilities, costs, and utilities were obtained from the Italian and international literature. Three types of surgeries were considered: gastric bypass, sleeve gastrectomy, and adjustable gastric banding. A base-case analysis was performed for the population, the characteristics of which were obtained from surgery candidates in Italy. Results In the base-case analysis, over 10 years, bariatric surgery led to cost increment of EUR 2,661 and generated additional 1.1 quality-adjusted life years (QALYs). Over a lifetime, surgery led to savings of EUR 8,649, additional 0.5 life years and 3.2 QALYs. Bariatric surgery was cost-effective at 10 years with an incremental cost-effectiveness ratio of EUR 2,412/QALY and dominant over conservative management over a lifetime. Conclusion In a comprehensive decision analytic model, a current mix of surgical methods for bariatric surgery was cost-effective at 10 years and cost-saving over the lifetime of the Italian patient cohort considered in this analysis.

Fracture of the penis is an uncommon emergency consisting of rupture of the tunica albuginea of the corpus cavernosum resulting from blunt trauma over an erect penis. Prompt diagnosis and early surgical repair are essential to ensure a successful outcome with minimal complications. Delay may result in devastating physical and psychological disabilities that are potentially avoidable. Here in this article, 7 cases of fracture penis are being reported, who had been managed successfully by surgery in 6 cases and one case treated conservatively as he refused surgery.

Lumbar disc herniation has a prevalence of up to 58% in the athletic population. Lumbar discectomy is a common surgical procedure to alleviate pain and disability in athletes. We systematically reviewed the current clinical evidence regarding athlete return to sport (RTS) following lumbar discectomy compared to conservative treatment. A computer-assisted literature search of MEDLINE, CINAHL, Web of Science, PEDro, OVID and PubMed databases (from inception to August 2015) was utilised using keywords related to lumbar disc herniation and surgery. The design of this systematic review was developed using the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Methodological quality of individual studies was assessed using the Downs and Black scale (0-16 points). The search strategy revealed 14 articles. Downs and Black quality scores were generally low with no articles in this review earning a high-quality rating, only 5 articles earning a moderate quality rating and 9 of the 14 articles earning a low-quality rating. The pooled RTS for surgical intervention of all included studies was 81% (95% CI 76% to 86%) with significant heterogeneity (I(2)=63.4%, p<0.001) although pooled estimates report only 59% RTS at same level. Pooled analysis showed no difference in RTS rate between surgical (84% (95% CI 77% to 90%)) and conservative intervention (76% (95% CI 56% to 92%); p=0.33). Studies comparing surgical versus conservative treatment found no significant difference between groups regarding RTS. Not all athletes that RTS return at the level of participation they performed at prior to surgery. Owing to the heterogeneity and low methodological quality of included studies, rates of RTS cannot be accurately determined. Published by the BMJ Publishing Group Limited.

Transboundary conservation: An ecoregional approach to protect neotropical migratory birds in South America

1996-11-01

Future conservation efforts will need to transcend geopolitical boundaries in efforts to protect entire landscapes and ecosystems. Neotropical migratory birds are as a group a useful conservation tool for linking diverse landscapes and people due to their dependence on multiple habitats, sensitivity to habitat changes, and universal public appeal. The conservation of neotropical migrants can therefore function as a powerful hemispheric umbrella for ecosystem protection. Efforts to protect neotropical migratory birds on their nonbreeding grounds have traditionally been focused on Mexico, Central America, and the Caribbean. To assess the importance of South America to neotropical migrants, an ecoregional classification system was used to determine species distributions in the Andean/Southern Cone Region (Bolivia, Colombia, Ecuador, Paraguay, Peru, and Venezuela). The occurrence of migrants in protected areas that are part of The Nature Conservancy's Parks in Peril program was also assessed. Of the 406 neotropical migrant species, nearly one third (132) occur as regular nonbreeding residents in the region and for almost half of these species (53), South America is their main nonbreeding ground. All Parks in Peril sites were found to harbor neotropical migrants. Forty-eight species (36%) have declining longterm North American Breeding Bird Survey population trends and/or high Partners in Flight concern scores and thus are of significant conservation concern. Most importantly, 29 species (22%) of conservation concern use South America as their primary nonbreeding ground, indicating a need for focused conservation action. The nature of the ecoregional approach used in this endeavor makes future prioritization of ecoregions and conservation strategies for neotropical migrants across national boundaries possible. The ability to link diverse landscapes using a common element such as migratory birds allows for unique transboundary partnerships and opportunities for habitat conservation, which support the goal of the Conservancy's new Migratory Bird Initiative.

Recently, it has been reported that impairment by an 8th cervical nerve root lesion can cause drop finger, namely C8 drop finger. Here, we report a clinical case series of C8 drop finger to reveal the clinical outcome of surgical treatments to allow for a better choice of treatment. The present study included 17 consecutive patients who were diagnosed as having C8 drop finger, in which muscle strength of the extensor digitorum communis (EDC) showed a manual muscle testing (MMT) grade of 3 or less. We retrospectively investigated the clinical characteristics of C8 drop finger and recovery of muscle power was measured by subtraction of preoperative MMT of the EDC from the final follow-up values. Nine cases showed recovery of muscle power of EDC, whereas the remaining eight cases did not show any recovery including two cases of deterioration. None of the conservatively treated patients showed any recovery. Surgically treated cases included two cases of deterioration. In the cases showing recovery, recovery began 9.9 months after surgery on average and recovery took 13.8 months after surgery on average. There was a significant difference in the recovery of MMT grade between the groups treated conservatively and surgically (p = 0.049). Preoperative MMT grade of EDC showed a moderate correlation with postoperative recovery (r 2  = 0.45, p = 0.003). In other words, the severity of preoperative muscular weakness correlated negatively with postoperative recovery. C8 drop finger is better treated by surgery than conservative therapy.

The use of latissimus dorsi miniflap for reconstruction following breast-conserving surgery: experience of a small breast unit in a district hospital.

Immediate reconstruction with autogenous tissue is one of the options for reconstruction following breast-conservation surgery for breast cancers in major centres with ready availability of appropriate skills. Immediate correction of volume deficit by latissimus dorsi miniflap (LDMF) in addition has cosmetic appeal by filling the defect without extra skin incision. Data was collected retrospectively from clinical records of 51 patients who underwent LDMF procedures in a district general hospital between June 2000 and December 2004, and the results were analysed. Postal questionnaire survey was done to assess the level of subjective satisfaction of the cosmetic outcome. Wide local excision and axillary-node sampling/clearance along with immediate reconstruction with a LDMF (involving a musculo-subcutaneous flap without skin) were performed in all patients. Patients' median age was 50 years. Sixty-five percent of the tumours were in the upper-outer quadrant, median weight of the specimen was 217.5 g (31-510 g), median clearance margin was 5 mm (0-15 mm) and median pathological size of the tumour was 20 mm (8-60 mm). Four patients required mastectomy later, whereas 1 patient had flap necrosis. At a median follow-up of 33 months, there has been no recurrence. Eighty-six percent of the patients who responded to the postal survey were satisfied with the cosmetic outcome. Immediate LDMF reconstruction is an acceptable way of correcting deformity after breast-conservation surgery. We demonstrate by our experience that it is a viable option for breast cancer in small district hospitals/ breast units.

Minimalist breast conserving surgical approaches for inferiorly sited cancers

PubMed Central

2017-01-01

Contemporary data suggests that breast conservation treatment (BCT) may confer a survival advantage when compared to mastectomy. Hence, it would be logical to adopt strategies which increase eligibility of successful BCT without compromising oncologic principles or cosmetic outcome. With respect to achieving good aesthetics, inferiorly sited breast cancers pose a particular technical challenge. A vast array of techniques, collectively referred to as oncoplastic breast surgery (OBS) have been developed to minimise post treatment distortion. The purported advantages of these approaches are the acquisition of wider margins and reduced re-excision rates. However, to date, there is a lack of data demonstrating significant reduction in local recurrence and overall survival when compared with less extensive procedures. In this review, “minimalist” procedures are described where strict oncologic criteria of clear margins are fulfilled and acceptable cosmesis are simultaneously achieved. These techniques offer less tissue loss, less extensive parenchymal mobilisation and shorter operating times without compromising margin status and aesthetics. They involve the combination of innovative incision designs and certain parenchymal resection patterns. Incision designs include the boomerang, golf-tee, anchor and arrowhead incisions which have been previously described but not widely used. Parenchymal resection patterns follow the “sick lobe hypothesis”. These techniques, termed “reductionist”, or “minimalist” comprising approaches where breast conserving surgery is condensed to its irreducible elements, offer alternatives which align with contemporary objectives of surgery where optimal survival outcomes are achieved through individualised procedures resulting in reduced iatrogenic impact. This logically allows scope for de-escalation of surgical therapy for breast cancer. PMID:28861382

The Burden of the Fellowship Interview Process on General Surgery Residents and Programs.

This study evaluated the effect of the fellowship interview process in a cohort of general surgery residents. We hypothesized that the interview process would be associated with significant clinical time lost, monetary expenses, and increased need for shift coverage. An online anonymous survey link was sent via e-mail to general surgery program directors in June 2014. Program directors distributed an additional survey link to current residents in their program who had completed the fellowship interview process. United States allopathic general surgery programs. Overall, 50 general surgery program directors; 72 general surgery residents. Program directors reported a fellowship application rate of 74.4%. Residents most frequently attended 8 to 12 interviews (35.2%). Most (57.7%) of residents reported missing 7 or more days of clinical training to attend interviews; these shifts were largely covered by other residents. Most residents (62.3%) spent over $4000 on the interview process. Program directors rated fellowship burden as an average of 6.7 on a 1 to 10 scale of disruption, with 10 being a significant disruption. Most of the residents (57.3%) were in favor of change in the interview process. We identified potential areas for improvement including options for coordinated interviews and improved content on program websites. The surgical fellowship match is relatively burdensome to residents and programs alike, and merits critical assessment for potential improvement. Published by Elsevier Inc.

Investigations performed in 41 patients with postoperative residual cavities after surgical interventions of different volume have shown high value of thoracoscopy as an additional diagnostic and curative method. The endoscopy findings determinate further curative tactics--surgery or conservative therapy.

Risks of conservative management in women with ovarian endometriomas undergoing IVF.

Classical surgical management of endometriotic ovarian cysts using the laparoscopic stripping technique has been recently questioned because of the surgical-related injury to the ovarian reserve. Accordingly, available guidelines suggest that endometriomas with a mean diameter below 4 cm should not be systematically removed before IVF procedures. However, conservative management may have some potential drawbacks and risks. The presence of the endometrioma may theoretically interfere with ovarian responsiveness to hyperstimulation and oocyte competence, the retrieval of the oocytes may be more difficult and risky, the disease may progress during the procedure, pregnancy outcome may be affected and there is the risk of missing occult malignancies with cancer development later in life. In the present review, we aimed at assessing whether these risks do exist and, if so, at estimating their clinical relevance. We searched PubMed for articles published in the English language between January 1990 and August 2014 that reported on endometriomas and assisted reproductive techniques. Special care was given to studies reporting data purporting to distinguish the effects of ovarian endometriomas per sé from those consequent to surgery for endometriosis or from endometriosis in general. Based on the evidence reviewed in the present study, it can be concluded that conservative management may actually expose women to four of the following theoretical risks, i.e. infection of the endometriomas, follicular fluid contamination with the endometrioma content, higher risk of pregnancy complications and cancer development later in life. The first three conditions do not justify surgery because these events are uncommon and the number of women needed to be treated would be exceedingly high and would not justify the costs and risks of the intervention. Albeit also very rare, the possibility of developing ovarian cancer later in life is more troublesome because it is a life-threatening condition. However, this alarmism is supported by only one cohort study and this risk can be effectively prevented by postponing surgery until after the IVF programme is concluded or when women have definitely satisfied their reproductive wishes. The available evidence on the risks of conservative management does not support systematic surgery before IVF in women with small ovarian endometriomas. © The Author 2015.

2015-12-01

Iatrogenic left main coronary artery (LMCA) dissection is a rare complication and may have devastating consequences if not immediately intervened. The management includes urgent revascularization mostly with percutaneous coronary intervention (PCI) with bail-out stenting and rarely requires coronary artery bypass graft (CABG) surgery. In clinically and hemodynamically stable patients, a conservative approach may be preferred. Here, we present a rare case of iatrogenic retrograde LMCA dissection due to pin-hole rupture of angioplasty balloon that was managed conservatively.

Cervical Radiculopathy due to Cervical Degenerative Diseases : Anatomy, Diagnosis and Treatment

PubMed Central

Kim, Kyoung-Tae

2010-01-01

A cervical radiculopathy is the most common symptom of cervical degenerative disease and its natural course is generally favorable. With a precise diagnosis using appropriate tools, the majority of patients will respond well to conservative treatment. Cervical radiculopathy with persistent radicular pain after conservative treatment and progressive or profound motor weakness may require surgery. Options for surgical management are extensive. Each technique has strengths and weaknesses, so the choice will depend on the patient's clinical profile and the surgeon's judgment. PMID:21430971

2017-03-01

Surgically induced necrotizing scleritis (SINS) is a rare but serious disorder that can develop many years after strabismus surgery. It is generally treated with high-dose steroids or immunosuppression. We describe a patient with Varadi Papp syndrome and congenital fibrosis of the extraocular muscles, who developed surgically induced necrotizing scleritis a month after strabismus surgery and was successfully managed by oral vitamin C and topical N-acetylcysteine 10%. While SINS is conventionally treated with steroids/immunosuppression, a conservative approach may be tried in milder cases. The role of topical N-acetylcysteine in managing this complication needs to be explored.

Antibiotic resistance is an imminent threat to worldwide public health. Dental professionals must demonstrate judicious use of antibiotics and educate their patients about the risks associated with their overuse. PURPOSE OF THE PAPER: To encourage the dental profession to prescribe responsibly in order to optimise the use of antibiotics in oral surgery. Antibiotic stewardship programmes are recommended to help reduce the emergence of infections that are multidrug-resistant. Clinical practice audits are encouraged to help dentists ensure conservative prescribing patterns. The dental profession has a duty of care to prescribe antibiotics in adherence with current best practice oral surgery guidelines. The dental profession must show leadership in slowing antibiotic resistance by pledgina to safeguard their appropriate use.

Consumption‐Based Conservation Targeting: Linking Biodiversity Loss to Upstream Demand through a Global Wildlife Footprint

Abstract Although most conservation efforts address the direct, local causes of biodiversity loss, effective long‐term conservation will require complementary efforts to reduce the upstream economic pressures, such as demands for food and forest products, which ultimately drive these downstream losses. Here, we present a wildlife footprint analysis that links global losses of wild birds to consumer purchases across 57 economic sectors in 129 regions. The United States, India, China, and Brazil have the largest regional wildlife footprints, while per‐person footprints are highest in Mongolia, Australia, Botswana, and the United Arab Emirates. A US$100 purchase of bovine meat or rice products occupies approximately 0.1 km2 of wild bird ranges, displacing 1–2 individual birds, for 1 year. Globally significant importer regions, including Japan, the United Kingdom, Germany, Italy, and France, have large footprints that drive wildlife losses elsewhere in the world and represent important targets for consumption‐focused conservation attention.

Climate Change Denial Books and Conservative Think Tanks

2013-01-01

The conservative movement and especially its think tanks play a critical role in denying the reality and significance of anthropogenic global warming (AGW), especially by manufacturing uncertainty over climate science. Books denying AGW are a crucial means of attacking climate science and scientists, and we examine the links between conservative think tanks (CTTs) and 108 climate change denial books published through 2010. We find a strong link, albeit noticeably weaker for the growing number of self-published denial books. We also examine the national origins of the books and the academic backgrounds of their authors or editors, finding that with the help of American CTTs climate change denial has spread to several other nations and that an increasing portion of denial books are produced by individuals with no scientific training. It appears that at least 90% of denial books do not undergo peer review, allowing authors or editors to recycle scientifically unfounded claims that are then amplified by the conservative movement, media, and political elites.

How and when do personal values guide our attitudes and sociality? Explaining cross-cultural variability in attitude-value linkages.

PubMed

Boer, Diana; Fischer, Ronald

2013-09-01

This article examines how and when personal values relate to social attitudes. Considering values as motivational orientations, we propose an attitude-value taxonomy based on Moral Foundation Theory (Haidt & Joseph, 2007) and Schwartz's (1992) basic human values theory allowing predictions of (a) how social attitudes are related to personal values, and (b) when macro-contextual factors have an impact on attitude-value links. In a meta-analysis based on the Schwartz Value Survey (Schwartz, 1992) and the Portrait Value Questionnaire (Schwartz et al., 2001; k = 91, N = 30,357 from 31 countries), we found that self-transcendence (vs. self-enhancement) values relate positively to fairness/proenvironmental and care/prosocial attitudes, and conservation (vs. openness-to-change) values relate to purity/religious and authority/political attitudes, whereas ingroup/identity attitudes are not consistently associated with value dimensions. Additionally, we hypothesize that the ecological, economic, and cultural context moderates the extent to which values guide social attitudes. Results of the multi-level meta-analysis show that ecological and cultural factors inhibit or foster attitude-value associations: Disease stress is associated with lower attitude-value associations for conservation (vs. openness-to-change) values; collectivism is associated with stronger attitude-value links for conservation values; individualism is associated with stronger attitude-value links for self-transcendence (vs. self-enhancement) values; and uncertainty avoidance is associated with stronger attitude-values links, particularly for conservation values. These findings challenge universalistic claims about context-independent attitude-value relations and contribute to refined future value and social attitude theories.

Identifying all moiety conservation laws in genome-scale metabolic networks.

PubMed

De Martino, Andrea; De Martino, Daniele; Mulet, Roberto; Pagnani, Andrea

2014-01-01

The stoichiometry of a metabolic network gives rise to a set of conservation laws for the aggregate level of specific pools of metabolites, which, on one hand, pose dynamical constraints that cross-link the variations of metabolite concentrations and, on the other, provide key insight into a cell's metabolic production capabilities. When the conserved quantity identifies with a chemical moiety, extracting all such conservation laws from the stoichiometry amounts to finding all non-negative integer solutions of a linear system, a programming problem known to be NP-hard. We present an efficient strategy to compute the complete set of integer conservation laws of a genome-scale stoichiometric matrix, also providing a certificate for correctness and maximality of the solution. Our method is deployed for the analysis of moiety conservation relationships in two large-scale reconstructions of the metabolism of the bacterium E. coli, in six tissue-specific human metabolic networks, and, finally, in the human reactome as a whole, revealing that bacterial metabolism could be evolutionarily designed to cover broader production spectra than human metabolism. Convergence to the full set of moiety conservation laws in each case is achieved in extremely reduced computing times. In addition, we uncover a scaling relation that links the size of the independent pool basis to the number of metabolites, for which we present an analytical explanation.

Improving management of small natural features on private lands by negotiating the science-policy boundary for Maine vernal pools.

Vernal pools are far more important for providing ecosystem services than one would predict based on their small size. However, prevailing resource-management strategies are not effectively conserving pools and other small natural features on private lands. Solutions are complicated by tensions between private property and societal rights, uncertainties over resource location and function, diverse stakeholders, and fragmented regulatory authority. The development and testing of new conservation approaches that link scientific knowledge, stakeholder decision-making, and conservation outcomes are important responses to this conservation dilemma. Drawing from a 15-y history of vernal pool conservation efforts in Maine, we describe the coevolution of pool conservation and research approaches, focusing on how research-based knowledge was produced and used in support of management decisions. As management shifted from reactive, top-down approaches to proactive and flexible approaches, research shifted from an ecology-focused program to an interdisciplinary program based on social-ecological systems. The most effective strategies for linking scientific knowledge with action changed as the decision-makers, knowledge needs, and context for vernal pool management advanced. Interactions among stakeholders increased the extent to which knowledge was coproduced and shifted the objective of stakeholder engagement from outreach to research collaboration and development of innovative conservation approaches. New conservation strategies were possible because of the flexible, solutions-oriented collaborations and trust between scientists and decision-makers (fostered over 15 y) and interdisciplinary, engaged research. Solutions to the dilemma of conserving small natural features on private lands, and analogous sustainability science challenges, will benefit from repeated negotiations of the science-policy boundary.

The mammalian genome is transcribed into large numbers of long noncoding RNAs (lncRNAs), but the definition of functional lncRNA groups has proven difficult, partly due to their low sequence conservation and lack of identified shared properties. Here we consider promoter conservation and positional conservation as indicators of functional commonality. We identify 665 conserved lncRNA promoters in mouse and human that are preserved in genomic position relative to orthologous coding genes. These positionally conserved lncRNA genes are primarily associated with developmental transcription factor loci with which they are coexpressed in a tissue-specific manner. Over half of positionally conserved RNAs in this set are linked to chromatin organization structures, overlapping binding sites for the CTCF chromatin organiser and located at chromatin loop anchor points and borders of topologically associating domains (TADs). We define these RNAs as topological anchor point RNAs (tapRNAs). Characterization of these noncoding RNAs and their associated coding genes shows that they are functionally connected: they regulate each other's expression and influence the metastatic phenotype of cancer cells in vitro in a similar fashion. Furthermore, we find that tapRNAs contain conserved sequence domains that are enriched in motifs for zinc finger domain-containing RNA-binding proteins and transcription factors, whose binding sites are found mutated in cancers. This work leverages positional conservation to identify lncRNAs with potential importance in genome organization, development and disease. The evidence that many developmental transcription factors are physically and functionally connected to lncRNAs represents an exciting stepping-stone to further our understanding of genome regulation.

Does conservation on farmland contribute to halting the biodiversity decline?

Biodiversity continues to decline, despite the implementation of international conservation conventions and measures. To counteract biodiversity loss, it is pivotal to know how conservation actions affect biodiversity trends. Focussing on European farmland species, we review what is known about the impact of conservation initiatives on biodiversity. We argue that the effects of conservation are a function of conservation-induced ecological contrast, agricultural land-use intensity and landscape context. We find that, to date, only a few studies have linked local conservation effects to national biodiversity trends. It is therefore unknown how the extensive European agri-environmental budget for conservation on farmland contributes to the policy objectives to halt biodiversity decline. Based on this review, we identify new research directions addressing this important knowledge gap. Copyright © 2011 Elsevier Ltd. All rights reserved.

To evaluate the bone refilling in the interface between the trabecular metal (TM) acetabular shell and the bone surface according to consecutive X film measuring after surgery. From July 2006 to July 2007, 35 patients (40 hips) accepted total hip replacement using trabecular metal monoblock acetabular cup system (TM). The cup was made of a ellipse shaped press fit Tantalum shell and high cross-linked PE liner (Longevity) with 28 mm inner diameter. The patients demography was: 16 male (20 hips), 19 female (20 hips), 5 bilateral hip replacements, age from 41 - 71 (mean 53), including 18 avascular necrosis hips, 16 osteoarthritis hips (including those secondary to a dysplasia hip), 4 avascular necrosis hips after femoral neck fracture, 2 Ankylosis Spondylitis. All the 40 total hip replacements used posterior approach, using hemispherical acetabular reamer and 2 mm press fit of final metal shell without screw fixation. The consecutive X film was taken at the end time of surgery and 2, 6, 12, 24 weeks, and 12 months. The clinical results was evaluate according to Harris scoring system, and the standard pelvis AP X film was measured at the interface between metal shell and the acetabular bone surface, witch was divided into five regions (A, B, C, D, E). Totally 32 patients (37 hips) were followed with average 8.7 months (7 - 12 months). The Harris before surgery was 50.5 (32 - 85), promoted to 91.0 (72 - 100), including 29 excellent, 6 good, 2 fair, and the total excellent and good rate was 94.6%. Complications include 4 patients leg length discrepancy from 1 - 2 cm, 3 patients moderate thigh pain and released after conservative therapy. No infection and dislocation was found. Twenty-one patients (23 hips) were found lucent line at the bone-metal interface from 1 - 5 mm, most common in B region and BC boundary than C, D, and CD boundary. All the patients followed was found the lucent line disappeared and refilled with bone at X film 24 weeks after surgery, however, no patients was found osteolysis and cup migration. The trabecular metal has strong capacity of bone conductive and bone inducement.

The European positional paper on rhinosinusitis and nasal polyps: has the introduction of guidance on the management of sinus disease affected uptake of surgery and acute admissions for sinusitis?

PubMed

Rhinosinusitis is a common condition with adults experiencing 2-5 episodes per year. The European Positional Paper on Rhinosinusitis and Nasal Polyps (EP3OS) published in 2005 and updated in 2007 provided evidence-based guidelines on the management of sinus disease promoting a conservative approach to treatment. This study examines the effect of EP3OS on sinus surgery uptake and acute admissions for sinusitis in England and Wales. A retrospective study using the national electronic health databases of England (Hospital Episodes Statistics, HES online) and Wales (Patient Episodes Database of Wales, PEDW) was undertaken from 2000 to 2010 using the OPCS-4 codes E12-E17 (sinus surgery) and ICD10 code J01 (acute admission for sinusitis). Data were analysed for effect following the introduction of the EP3OS in 2005 using linear regression and Chi squared analysis. 116,370 sinus procedures and 10,916 acute admissions for sinusitis were made during the study period. No significant decrease in sinus surgery procedures occurred following the introduction of the EP3OS as may have been expected (p > 0.05), although subgroup analysis suggested a significant increase in Wales (p < 0.05). In addition, significant increases in acute admissions for sinusitis were observed following the introduction of EP3OS (p < 0.05). However, subgroup analysis suggested this was not the case in Wales (p > 0.05). The EP3OS appears to have had little impact on the rates of sinus surgery but more conservative approaches to managing of sinus disease may have led to an increase in acute admissions. Further research is required to investigate whether changes in practice were adopted.

Impact of obesity treatment on gastroesophageal reflux disease

Gastroesophageal reflux disease (GERD) is a frequently encountered disorder. Obesity is an important risk factor for GERD, and there are several pathophysiologic mechanisms linking the two conditions. For obese patients with GERD, much of the treatment effort is focused on weight loss and its consistent benefit to symptoms, while there is a relative lack of evidence regarding outcomes after novel or even standard medical therapy is offered to this population. Physicians are hesitant to recommend operative anti-reflux therapy to obese patients due to the potentially higher risks and decreased efficacy, and these patients instead are often considered for bariatric surgery. Bariatric surgical approaches are broadening, and each technique has emerging evidence regarding its effect on both the risk and outcome of GERD. Furthermore, combined anti-reflux and bariatric options are now being offered to obese patients with GERD. However, currently Roux-en-Y gastric bypass remains the most effective surgical treatment option in this population, due to its consistent benefits in both weight loss and GERD itself. This article aims to review the impact of both conservative and aggressive approaches of obesity treatment on GERD. PMID:26819528

Obesity in Neurosurgery: A Narrative Review of the Literature.

2017-10-01

Obesity is an important consideration in neurosurgical practice. Of Australian adults, 28.3% are obese and it is estimated that more than two thirds of Australia's population will be overweight or obese by 2025. This review of the effects of obesity on neurosurgical procedures shows that, in patients undergoing spinal surgery, an increased body mass index is a significant risk factor for surgical site infection, venous thromboembolism, major medical complications, prolonged length of surgery, and increased financial cost. Although outcome scores and levels of patient satisfaction are generally lower after spinal surgery in obese patients, obesity is not a barrier to deriving benefit from surgery and, when the natural history of conservative management is taken into account, the long-term benefits of surgery may be equivalent or even greater in obese patients than in nonobese patients. In cranial surgery, the impact of obesity on outcome and complication rates is generally lower. Specific exceptions are higher rates of distal catheter migration after shunt surgery and cerebrospinal fluid leak after posterior fossa surgery. Minimally invasive approaches show promise in mitigating some of the adverse effects of obesity in patients undergoing spine surgery but further studies are needed to develop strategies to reduce obesity-related surgical complications.

To describe conservative and surgical foot care in patients with RA in England and explore factors that predict the type of foot care received. Use of podiatry and type of foot surgery were outcomes recorded in an inception cohort involving nine rheumatology centres that recruited patients with RA between 1986 and 1998 across England. Associations between patient-specific factors and service use were identified using univariate logistic regression analyses. The independence of these associations was then verified through multiple binary logistic regression modelling. Data were collected on 1237 patients with RA [66.9% females, mean (s.d.) age at disease onset = 54.36 (14.18) years, median DAS = 4.09 (1st quartile = 3.04, 3rd quartile = 5.26), median HAQ = 1 (0.50, 1.63)]. Interventions involving the feet in the cohort were low with only 364 (30%) out of 1218 receiving podiatry and 47 (4%) out of 1237 patients having surgery. At baseline, female gender, increasing age at onset, being RF positive and higher DAS scores were each independently associated with increased odds of seeing a podiatrist. Gender, age of onset and baseline DAS were independently associated with the odds of having foot surgery. Despite the known high prevalence of foot pathologies in RA, only one-third of this cohort accessed podiatry. While older females were more likely to access podiatry care and younger patients surgery, the majority of the RA population did not access any foot care.

We retrospectively investigated the possible influence of a simultaneous integrated boost (SIB), hypofractionation and oncoplastic surgery on cosmetic outcome in 125 patients with stage I-II breast cancer treated with breast conserving therapy (BCT). The boost was given sequentially (55%) or by SIB (45%); fractionation was conventional (83%) or hypofractionated (17%); the surgical technique was a conventional lumpectomy (74%) or an oncoplastic technique (26%). We compared cosmetic results subjectively using a questionnaire independently completed by the patient and by the physician and objectively with the BCCT.core software. Independent-samples T-tests were used to compare outcome in different groups. Patients also completed the EORTC QLQ C30 and BR23. Univariate analyses indicated no significant differences of the cosmetic results (P ≤ 0.05) for the type of boost or fractionation. However, the conventional lumpectomy group scored significantly better than the oncoplastic group in the BCCT.core evaluation, without a significant difference in the subjective cosmetic evaluation. Quality of life outcome was in favour of SIB, hypofractionation and conventional surgery. Our study indicates that the current RT techniques seem to be safe for cosmetic outcome and quality of life. Further investigation is needed to verify the possible negative influence of oncoplastic surgery on the cosmetic outcome and the quality of life as this technique is especially indicated for patients with an unfavourable tumour/breast volume ratio.

Gava, A; Coghetto, F

1989-05-01

Twenty-four lectures were reviewed of the XXXIII SIRMN National Congress (Rome, October 1988) on the conservative radiosurgical treatment of breast cancer. A whole of 3462 cases were divided into 2 groups: group A--2824 patients who underwent targeted radiotherapy after conservative surgery (mostly quadrantectomy)--and group B--638 patients where, in case of N+ and internal quadrant tumors, irradiation was extended to lymph nodes. No significant differences were demonstrated between group A and group B as far as loco-regional relapses were concerned. Thus, no significant advantage seems to be yielded by lymph node irradiation in the early treatment of breast cancer.

Intestinal diversion (colostomy or ileostomy) in patients with severe bowel dysfunction following spinal cord injury.

PubMed

Hocevar, Barbara; Gray, Mikel

2008-01-01

Spinal cord injury (SCI) affects motor and sensory nervous integrity resulting in paralysis of lower or both upper and lower extremities, as well as autonomic nervous system function resulting in neurogenic bowel. SCI leads to diminished or lost sensations of the need to defecate or inability to distinguish the presence of gas versus liquid versus solid stool in the rectal vault. Sensory loss, incomplete evacuation of stool from the rectal vault, immobility, and reduced anal sphincter tone increase the risk of fecal incontinence. Gastrointestinal symptoms are associated with depression, anxiety, and significant impairments in quality of life (QOL) in a significant portion of persons with SCI. 1. To compare clinical, functional, or quality of life outcomes in spinal cord injured patients with gastrointestinal symptoms managed by conservative measures versus intestinal diversion (colostomy or ileostomy). 2. To identify complications associated with ostomy surgery in patients with bowel dysfunction and SCI. A systematic review of electronic databases MEDLINE and CINAHL (from January 1960 to November 2007) was undertaken using the following key words: (1) ostomy, (2) stoma, (3) colostomy, and (4) ileostomy. Boolean features of these databases were used to combine these terms with the key word "spinal cord injuries." Prospective and retrospective studies that directly compared clinical, functional, QOL outcomes or satisfaction among patients with intestinal diversions to patients managed by conservative means were included. Creation of an ostomy in selected patients provides equivocal or superior QOL outcomes when compared to conservative bowel management strategies. Both colostomy and ileostomy surgery significantly reduce the amount of time required for bowel management. Patients who undergo ostomy surgery tend to be satisfied with their surgery, and a significant portion report a desire to be counseled about this option earlier. There are no clear advantages when functional, clinical, or QOL outcomes associated with colostomy are compared to those seen in SCI patients undergoing ileostomy. 1. The WOC nurse plays a pivotal role in both conservative bowel management and the decision to undergo ostomy surgery. 2. Preoperative stoma site marking is vital for the best surgical outcome. 3. The system best suited to an individual is based on a variety of factors including but not limited to stoma location, type of effluent, peristomal plane and contours, and the individual's capabilities and preferences. 4. Some individuals with a sigmoid or descending colostomy may benefit from colostomy irrigation as a management method. 5. Postoperatively, assessment of pressure points for signs of tissue breakdown, evaluation of treatment methods for existing pressure ulcers with suitable modification, and support surface assessment should be included in ongoing annual follow-up visits.

Synovial chondromatosis (SC) is an uncommon disease characterized by a benign nodular cartilaginous proliferation arising from the joint synovium, bursae, or tendon sheaths. Although the temporomandibular joint is rarely affected by neoplastic lesions, SC is the most common neoplastic lesion of this joint. The treatment of this disease consists in the extraoral surgery with a wide removal of the lesion; in this study, the authors described a more conservative intraoral surgical approach. Patient with SC of temporomandibular joint typically refer a limitation in the mouth opening, together with a persistent not physiological mandibular protrusion and an appearance of a neoformation located at the right preauricular region: the authors reported 1 scholar patient. After biopsy of the neoformation, confirming the synovial chondromatosis, the patient underwent thus to the surgical excision of the tumor, via authors' conservative transoral approach, to facilitate the enucleation of the neoformation. The mass fully involved the pterygo-maxillary fossa with involvement of the parotid lodge and of the right TMJ: this multifocal extension suggested for a trans-oral surgical procedure, in the light of the suspicion of a possible malignant nature of the neoplasm. Our intraoral conservative approach to surgery is aimed to reduce the presence of unaesthetic scars in preauricular and facial regions, with surgical results undoubtedly comparable to the traditional surgical techniques much more aggressive. Our technique could be a valid, alternative, and safe approach to treat this rare and complex kind of oncological disease.

We evaluate the empirical and theoretical support for the hypothesis that a large proportion of native species richness is required to maximize ecosystem stability and sustain function. This assessment is important for conservation strategies because sustenance of ecosystem functions has been used as an argument for the conservation of species. If ecosystem functions are sustained at relatively low species richness, then arguing for the conservation of ecosystem function, no matter how important in its own right, does not strongly argue for the conservation of species. Additionally, for this to be a strong conservation argument the link between species diversity and ecosystem functions of value to the human community must be clear. We review the empirical literature to quantify the support for two hypotheses: (1) species richness is positively correlated with ecosystem function, and (2) ecosystem functions do not saturate at low species richness relative to the observed or experimental diversity. Few empirical studies demonstrate improved function at high levels of species richness. Second, we analyze recent theoretical models in order to estimate the level of species richness required to maintain ecosystem function. Again we find that, within a single trophic level, most mathematical models predict saturation of ecosystem function at a low proportion of local species richness. We also analyze a theoretical model linking species number to ecosystem stability. This model predicts that species richness beyond the first few species does not typically increase ecosystem stability. One reason that high species richness may not contribute significantly to function or stability is that most communities are characterized by strong dominance such that a few species provide the vast majority of the community biomass. Rapid turnover of species may rescue the concept that diversity leads to maximum function and stability. The role of turnover in ecosystem function and stability has not been investigated. Despite the recent rush to embrace the linkage between biodiversity and ecosystem function, we find little support for the hypothesis that there is a strong dependence of ecosystem function on the full complement of diversity within sites. Given this observation, the conservation community should take a cautious view of endorsing this linkage as a model to promote conservation goals.

[Lumbar disc herniation: Natural history, role of physical examination, timing of surgery, treatment options and conflicts of interests].

Indication for surgery in lumbar disc herniation (LDH) varies widely depending on the geographical area. A literature review is presented on the natural history, role of physical examination, timing of surgery, evidence-based treatment, and conflicts of interests in LDH. Surgery is shown to provide significant faster relief of pain compared to conservative therapy, although the effect fades after a year. There is no treatment modality better than the rest in terms of pain control and neurological recovery, nor is there a surgical technique clearly superior to simple discectomy. The lack of sound scientific evidence on the surgical indication may contribute to its great geographical variability. Since LDH has a favourable natural history, neuroimaging and surgery should not be considered until after a 6-week period. It is necessary to specify and respect the surgical indications for LDH, avoiding conflicts of interests. Copyright © 2016 Sociedad Española de Neurocirugía. Publicado por Elsevier España, S.L.U.

Endometriosis is a chronic disease. The pathogenesis is actually still unclear. Endometriosis is responsible for infertility and/or pelvic pain. One of the most important features of the disease is the heterogeneity (clinical and anatomical). Among the different phenotypes of endometriosis, the ovarian endometrioma seems to most important lesion in the management of endometriosis-related infertility. Surgical treatment is associated to a decrease of the ovarian reserve and a potential detrimental effect on in vitro fecondation (IVF) outcomes. Thus, the choice between conservative or surgical management of endometrioma before IVF is actually debated. The advantages and drawback of surgical and conservative management should be discussed before to plan the treatment. In the present review, we aimed at assessing the risks of a conservative management of endometrioma as compared to surgery before IVF. Copyright © 2017. Published by Elsevier Masson SAS.

To evaluate the cost-effectiveness of bariatric surgery in Italy from a third-party payer perspective over a medium-term (10 years) and a long-term (lifetime) horizon. A state-transition Markov model was developed, in which patients may experience surgery, post-surgery complications, diabetes mellitus type 2, cardiovascular diseases or die. Transition probabilities, costs, and utilities were obtained from the Italian and international literature. Three types of surgeries were considered: gastric bypass, sleeve gastrectomy, and adjustable gastric banding. A base-case analysis was performed for the population, the characteristics of which were obtained from surgery candidates in Italy. In the base-case analysis, over 10 years, bariatric surgery led to cost increment of EUR 2,661 and generated additional 1.1 quality-adjusted life years (QALYs). Over a lifetime, surgery led to savings of EUR 8,649, additional 0.5 life years and 3.2 QALYs. Bariatric surgery was cost-effective at 10 years with an incremental cost-effectiveness ratio of EUR 2,412/QALY and dominant over conservative management over a lifetime. In a comprehensive decision analytic model, a current mix of surgical methods for bariatric surgery was cost-effective at 10 years and cost-saving over the lifetime of the Italian patient cohort considered in this analysis. © 2017 The Author(s) Published by S.

Surgical management of peptic ulcer disease today--indication, technique and outcome.

PubMed

Zittel, T T; Jehle, E C; Becker, H D

2000-03-01

The current surgical management of peptic ulcer disease and its outcome have been reviewed. Today, surgery for peptic ulcer disease is largely restricted to the treatment of complications. In peptic ulcer perforation, a conservative treatment trial can be given in selected cases. If laparotomy is necessary, simple closure is sufficient in the large majority of cases, and definitive ulcer surgery to reduce gastric acid secretion is no longer justified in these patients. Laparoscopic surgery for perforated peptic ulcer has failed to prove to be a significant advantage over open surgery. In bleeding peptic ulcers, definitive hemostasis can be achieved by endoscopic treatment in more than 90% of cases. In 1-2% of cases, immediate emergency surgery is necessary. Some ulcers have a high risk of re-bleeding, and early elective surgery might be advisable. Surgical bleeding control can be achieved by direct suture and extraluminal ligation of the gastroduodenal artery or by gastric resection. Benign gastric outlet obstruction can be controlled by endoscopic balloon dilatation in 70% of cases, but gastrojejunostomy or gastric resection are necessary in about 30% of cases. Elective surgery for peptic ulcer disease has been largely abandoned, and bleeding or obstructing ulcers can be managed safely by endoscopic treatment in most cases. However, surgeons will continue to encounter patients with peptic ulcer disease for emergency surgery. Currently, laparoscopic surgery has no proven advantage in peptic ulcer surgery.

Surgical repair is a common treatment for inguinal hernias but a substantial number of patients experience chronic pain after surgery. As some patients are pain-free on presentation, it is important to investigate whether patients perceive the treatment to be beneficial. The present study used qualitative methods to explore experiences of pain, activity limitations and satisfaction with treatment as people underwent surgery and recovery. Twenty-nine semi-structured interviews were conducted. Seven participants were interviewed longitudinally: before surgery and two weeks and four months post-surgery. Ten further participants with residual pain four months post-surgery were interviewed once. Semi-structured interviews included experience and perception of pain; activity limitations; reasons for having surgery; satisfaction with the decision to undergo surgery. A thematic analysis was conducted. Pain did not cause concern when perceived as part of the usual surgery and recovery processes. Activity was limited to avoid damage to the hernia site rather than to avoid pain. None of the participants reported dissatisfaction with the decision to have surgery; reducing the risk of life-threatening complications associated with untreated hernias was considered important. These findings suggest that people regarded surgical treatment as worthwhile, despite chronic post-surgical pain. Further research should ascertain whether patients are aware of the actual risk of complications associated with conservative rather than surgical management of inguinal hernia. PMID:26973903

To determine the prognosis of patients with necrotic acute pancreatitis receiving medical and surgical treatments. The severe acute pancreatitis treatment is multidisciplinary and requires a daily evaluation of the patient that will allow to observe changes and apply therapy in due time. The treatment includes: Admission in the ICU, fluids, nutrition and antibiotics, as well as other life supports for high-risk patients. Thus, patients undergo conservative treatment or, if it is necessary, surgery. A retrospective study of patients with necrotic acute pancreatitis admitted to the ICU between January 2004 and August 2006. The patients with necrotic acute pancreatitis without signs of sepsis underwent a conservative medical treatment, while fine needle punction-aspiration was performed in all patients who were suffering from necrotic acute pancreatitis and persistent sepsis four weeks after their admission and after discarding and eradicating every non-pancreatic focus of infection. All Gram stain or culture positive patients underwent surgery immediately. Seventy patients with necrotic acute pancreatitis were included in the study. Thirty-six patients (51%) suffered acute pancreatitis with sterile necrosis and underwent a conservative treatment, while 34 patients (49%) developed acute pancreatic with infected necrosis and underwent surgery. The average age was 55.19 vs. 57.65 (p=0.57). The average amylase was 1421.74 vs. 1402.45. (p=0.96). The tomography severity index was 8.47 vs. 8.79 (p=0.36). The Apache II was 8.22 vs. 9 (p=0.46). The average number of failed organs was 0.39 vs. 0.68. (p=0.19). The ICU stay was 10.75 vs. 26.5 days (p<0.05) while the total hospital stay was 46.47 vs. 57.26 days (p<0.05). The mortality rate was (3/36) 8.3% vs. (9/34) 26.5% (p<0.05) for conservative medical treatment vs. surgical treatment, respectively. Between the first and the twelfth month the evaluated patients who attended consultation, after discharge, showed: pancreatic pseudocyst 9/36 (25%) vs. 8/34(23.5%); recurring abdominal pain 3/36 (8.3%) vs. 4/34 (11.8%); and relapsing acute pancreatitis 3/36 (8.3%) vs. 2/34 (5.8%); while 4/36 (11.1%) vs. 3/34 (8.8%) did not show any problem. There were not significant differences between the conservative and the surgical medical treatment, respectively. Patients suffering acute pancreatitis with sterile necrosis can undergo conservative medical treatment which will result in a lower mortality rate, while the hospital stay, in comparison with acute pancreatitis with infected necrosis, will not be affected.

Endoscopy Assisted Oncoplastic Breast Surgery (EAOBS)

Endoscopic oncoplastic breast surgery represents a minimal invasive approach with the aim of both removing cancer safely and also restoring the breast image. It has less noticeable scar, excellent cosmetic outcomes, high patient satisfaction rate and recently reported relatively long term safety. Operative techniques for both endoscopic breast conserving surgery and endoscopic nipple/areola/skin sparing mastectomy have been described in detail. Two different working planes in which one of them is subcutaneous and the other one is sub-mammary planes are being used during the surgery. Surgical techniqe needs some instruments such as endoscopic retractor, light guided specific mammary retractor, wound protector and bipolar scissor. Endoscopic breast retractors provide magnified visualization and extensive posterior dissection facility. Tunneling method and hydrodissection simplify the technique in the subcutaneous field. Oncoplastic reconstruction techniques are also applied after the tumor resection by endoscopic method. Complication rates of endoscopic breast surgery are similar to open breast surgery rates. Quite succesful local recurrence, distant metastasis and overall survival rates have been declared. However it looks reasonable to wait for the results with longer follow-up before having a judgement about oncologic efficiency and safety of the endoscopic breast cancer surgery. PMID:28331692

X-linked agammaglobulinemia (XLA) is a congenital immune deficiency disorder caused by abnormal antibody production. It is a rare disease with an estimated frequency of 1 in 379,000 that has X-linked recessive heredity and develops only in males. The clinical problems include bacterial infection such as otitis media, sinusitis, and bronchitis. In recent years it has become possible to diagnose XLA in the early stage and intravenous immunoglobulin replacement therapy has permitted survival to adulthood. However, there have been no reports of oral surgery in patients with XLA. Here, we describe a case in which immunoglobulin replacement therapy given pre- and postoperatively was used to control infection in oral surgery and maxillary distraction osteogenesis performed for improving occlusion and appearance of a cleft lip and palate in a patient with XLA.

Chylous ascites is an extremely rare complication of abdominal aortic surgery. A case with a successful outcome is presented, followed by a review of the 17 published cases. Chylous ascites can result in nutritional imbalance, immunological deficit and respiratory dysfunction. Paracentesis confirms the diagnosis and provides symptomatic relief. Conservative management, beginning with a low-fat diet and medium-chain triglyceride (MCT) supplementation, is recommended, changing to total parenteral nutrition if unsuccessful. Failure of non-operative treatment may necessitate the need for laparotomy and ligation of leaking lymphatics or peritoneovenous shunting.

We report on a female preterm infant of 29 wk gestational age, who developed acquired lobar emphysema after prolonged artificial ventilation secondary to respiratory disease syndrome and bronchopulmonary dysplasia. The infant underwent atypical segmentectomy at the age of 12 mo because of life-threatening hypoxaemia with pulmonary hypertension and failure of conservative treatment. Lung volume reduction surgery (LVRS) dramatically improved the respiratory function and resulted in adequate weight gain and psychomotor development. In selected cases LVRS can be an option for lobar emphysema in premature infants with severe bronchopulmonary dysplasia.

Breast sarcomas are exceptionally rare mesenchymal neoplasms composed of many histologic subtypes. Therapy is guided by principles established in the management of extremity sarcomas. The anatomic site does influence treatment decisions, particularly the surgical management. Surgery should be undertaken with the aim of achieving a widely negative margin. Selected patients can be managed with breast-conserving surgery. Breast reconstruction is increasingly being undertaken for selected patients. Radiation therapy and chemotherapy are used selectively for large, high-grade sarcomas for which there is significant concern for local and distant recurrence. Copyright © 2016 Elsevier Inc.

Deconstructing Community for Conservation: Why Simple Assumptions are Not Sufficient.

Waylen, Kerry Ann; Fischer, Anke; McGowan, Philip J K; Milner-Gulland, E J

2013-01-01

Many conservation policies advocate engagement with local people, but conservation practice has sometimes been criticised for a simplistic understanding of communities and social context. To counter this, this paper explores social structuring and its influences on conservation-related behaviours at the site of a conservation intervention near Pipar forest, within the Seti Khola valley, Nepal. Qualitative and quantitative data from questionnaires and Rapid Rural Appraisal demonstrate how links between groups directly and indirectly influence behaviours of conservation relevance (including existing and potential resource-use and proconservation activities). For low-status groups the harvesting of resources can be driven by others' preference for wild foods, whilst perceptions of elite benefit-capture may cause reluctance to engage with future conservation interventions. The findings reiterate the need to avoid relying on simple assumptions about 'community' in conservation, and particularly the relevance of understanding relationships between groups, in order to understand natural resource use and implications for conservation.

Introduction The selection of treatment for local recurrence in patients with non-small-cell lung cancer (NSCLC) depends on the possibility of performing a radical tumor resection, the patient's performance status, and cardiopulmonary efficiency. Compared with chemoradiotherapy, surgical treatment offers a greater chance of long-term survival, but results in completion pneumonectomy and is associated with a relatively high rate of complications. Aim of the study Aim of the study was to evaluate early and long-term results of surgery and conservative treatment (chemoradiotherapy) in patients with local NSCLC recurrence. Material and methods Between 1998 and 2011, 1697 NSCLC patients underwent lobectomy or bilobectomy at the Department of Thoracic Surgery in Poznań. Among them, 137 patients (8.1%) were diagnosed with cancer recurrence; chemotherapy or chemoradiotherapy was provided to 116 patients; 21 patients (15.3%) were treated with completion pneumonectomy. The median time from primary surgery to recurrence was 13.4 months. No metastases to N2 lymph nodes were observed among the patients undergoing surgery; in 7 patients N1 lymph node metastases were confirmed. Results The rate of complications after surgery was significantly higher in comparison with conservative therapy (80.9% vs. 48.3%). Patients treated with surgery were most likely to suffer from complications associated with the circulatory system (80.9%), while hematologic complications were dominant in the group undergoing oncological treatment (41.4%). There were no perioperative deaths after completion pneumonectomy. The age of the patients was the only factor which significantly influenced the incidence of complications in both groups of patients. Analysis of the survival curves demonstrated statistically significant differences in survival between the groups treated with surgery, chemoradiotherapy, and chemotherapy (p = 0.00001). Five-year survival probability was significantly higher among patients treated surgically as compared to patients undergoing systemic therapy. Conclusions Despite the significant rate of postoperative complications (mostly circulatory), the long-term results of the surgical treatment of local NSCLC recurrence are more favorable than those achieved with chemoradiotherapy. The success of surgical treatment is conditioned on the exclusion of metastasis in N2 lymph nodes. PMID:26336473

Oncoplastic breast conserving surgery (OBCS) allows women who may otherwise have mastectomy and immediate reconstruction (MxIR) the choice to conserve their breast yet avoid deformity. We compared the outcome of these options. Two cohorts meeting study criteria were identified from prospectively audited series of women undergoing OBCS or MxIR. After case matching for age, tumour size and date of surgery, stratification by breast size and controlling for radiotherapy; body image scale (BIS) scores of psychosocial function and patient reported outcome measures (PROMs) for breast appearance and return to function were analysed. A total of 567 women (286 treated by OBCS and 281 by MxIR) fulfilled inclusion criteria. Demographics were similar between the two unmatched cohorts, except for radiotherapy, age and tumour size (all p < 0.001). Overall, BIS score (p = 0.002), self-rated breast appearance, return to work and function (all p < 0.001) significantly favoured OBCS. Case-matched women with larger breasts treated by OBCS reported better BIS scores (mean 3.30 vs. 5.37, p = 0.011) and self-rated breast appearance score (p < 0.001) than MxIR, whereas no significant difference was observed for smaller breasts. BIS and appearance favoured OBCS, regardless of whether radiotherapy would have been avoided if treated by MxIR. OBCS offers suitable women the option to avoid MxIR while providing faster recovery. Better psychosocial and self-rated satisfaction with breast appearance is achieved for OBCS in all groups, regardless of the need for radiotherapy, apart from those women with smaller breasts for whom the results are comparable.

The present study was performed to explore the prognostic significance of periostin expression in a cohort of patients with early-stage breast cancer treated with breast conserving surgery following radiotherapy. A tissue microarray of tumor samples from 259 patients with early-stage breast cancer was assayed for periostin, estrogen receptor (ER), progesterone receptor (PR), ErbB2 receptor tyrosine kinase 2 and Ki-67 expression by immunohistochemistry. The association of periostin with other clinicopathological parameters and clinical outcomes, including local recurrence free survival (RFS), distant metastasis free survival (DFS) and overall survival (OS), were assessed through log-rank tests and univariate and multivariate analysis. Periostin expression was identified in 91 of the 259 tissue samples (35%). The periostin status was significantly associated with histological grade (P=0.001), nodal status (P=0.023), molecular subtype (P<0.01), ER status (P<0.01), PR status (P<0.01) and Ki-67 expression (P=0.011). Furthermore, periostin expression was associated with an increased risk of five-year local recurrence (95.8% vs. 89.0%; P=0.017) and distant metastasis (92.3% vs. 79.1%; P=0.001) in patients with early stage breast cancer. Multivariate analysis using Cox's proportional hazards model demonstrated that periostin expression was an independent predictor of all clinical outcomes in breast cancer (RFS, P=0.018; DFS, P=0.025; OS, P=0.047). Therefore, it was concluded that periostin is associated with an increased risk of local relapse and distant metastasis in early-stage breast cancer treated with conserving surgery and radiotherapy. This association should be further investigated in larger cohorts to validate the clinical significance of periostin expression.

Background The aim of the study was to identify risk factors for positive surgical margins in breast-conserving surgery for breast cancer and to evaluate the influence of surgical experience in obtaining complete resection. Methods All lumpectomies for invasive breast carcinoma and ductal carcinoma in situ (DCIS) between April 2008 and March 2010 were selected from the database of a single institution. Re-excision rates for positive margins as well as patient and histopathologic tumor characteristics were analyzed. Surgical experience was staged by pairs made of Resident plus Specialist or Consultant. Two periods were defined. During period A, the majority of operations were performed by Residents under supervision of Specialist or Consultant. During period B, only palpable tumors were operated by Residents. Results The global re-excision rate was 27% (50 of 183 patients). The presence of DCIS increased the risk for positive margins: 60% (nine of 15 patients) in the case of sole DCIS compared to 26% (41 of 160 patients) for invasive cancer (p = 0.005) and 35% (42 of 120 patients) in the case of peritumoral DCIS compared to 11% (seven of 62 patients) in the case of sole invasive cancer (p = 0.001). Re-excision rate decreased from 36% (23 of 64 patients) during period A to 23% (27 of 119 patients) during period B (p = 0.055). There was no significant difference between the surgical pairs. Conclusion In our study, DCIS was the only risk factor for positive surgical margins. Breast-conserving surgery for non-palpable tumors should be performed by Specialists, however, palpable tumors can be safely operated by Residents under supervision.

To describe a clinical treatment algorithm for posterior ankle impingement (PAI) syndrome in professional football players. A case series of 26 elite professional football players diagnosed and treated for posterior ankle impingement syndrome were included for the study. All of the athletes received conservative treatment with physical therapy modalities initially. If the first line medical treatment and rehabilitation was ineffective to alleviate the symptoms, ultrasound-guided corticosteroid injection was proposed and thereafter the patients underwent posterior ankle arthroscopy if the complaints are still unresolved. The pain scores (AOFAS, VAS), and time to return to play were the main outcome measures. The complaints of 18 (69.2%) players were subsided with non-surgical treatment whereas three of acute cases and five of the chronic cases did not respond to medical treatment and arthroscopic surgery was performed for eight athletes. Eighteen players returned to training for a mean time of 36.3 days (24-42 days) after conservative treatment. The patients who underwent arthroscopic surgery returned to training for a mean time of 49.8 days (42-56 days) after the surgery. All athletes returned to their previous level of competition after treatment without any complications or recurrence in a mean follow-up 36.5 months (19-77 months). Non-surgical treatment modalities were effective in 2/3 of posterior ankle impingement syndrome in elite football players. On the other hand, posterior ankle arthroscopy is safe and effective treatment option for posterior ankle impingement syndrome if the conservative treatment fails. Level IV, Therapeutic study.

Re-resection rate after breast-conserving surgery (BCS) has been introduced as an indicator of quality of surgical treatment in international literature. The present study aims to develop a case-mix model for re-resection rates and to evaluate its performance in comparing results between hospitals. Electronic records of eligible patients diagnosed with in-situ and invasive breast cancer in 2006 and 2007 were derived from 16 hospitals in the Rotterdam Cancer Registry (RCR) (n = 961). A model was built in which prognostic factors for re-resections after BCS were identified and expected re-resection rate could be assessed for hospitals based on their case mix. To illustrate the opportunities of monitoring re-resections over time, after risk adjustment for patient profile, a VLAD chart was drawn for patients in one hospital. In general three out of every ten women had re-surgery; in about 50% this meant an additive mastectomy. Independent prognostic factors of re-resection after multivariate analysis were histological type, sublocalisation, tumour size, lymph node involvement and multifocal disease. After correction for case mix, one hospital was performing significantly less re-resections compared to the reference hospital. On the other hand, two were performing significantly more re-resections than was expected based on their patient mix. Our population-based study confirms earlier reports that re-resection is frequently required after an initial breast-conserving operation. Case-mix models such as the one we constructed can be used to correct for variation between hospitals performances. VLAD charts are valuable tools to monitor quality of care within individual hospitals. Copyright © 2011 Elsevier Ltd. All rights reserved.

The aim of surveys on clinical practice is to stimulate discussion and optimize practice. In this paper the current Italian radiotherapy practice after breast-conserving surgery for early breast cancer is described and adherence to national and international guidelines is assessed. Furthermore, results are compared with an earlier survey in northern Italy and international reports. A multiple-choice questionnaire sent to all 138 Italian radiation oncology centers. 48% of centers responded. Most performed breast-conserving surgery when tumor size was < or =3 cm. All centers routinely performed axillary dissection; 45 carried out sentinel node biopsy followed by axillary dissection when the sentinel node was positive. Most centers re-excised when resection margins were positive. The median interval between surgery and radiotherapy, when chemotherapy was not administered, was 60 days. Adjuvant chemotherapy was preferably administered before radiotherapy. Regional lymph nodes were never irradiated in 10 centers; in all others irradiation depended on the number of positive lymph nodes and/or involvement of axillary fat and/or tumor location in medial quadrants. All centers used standard fractionation; hypofractionated schemes were available in 6. Most centers used 4-6 MV photons. In 59 centers the boost dose of 10 Gy could be increased if margins were not negative. All centers ensured patient setup reproducibility. Treatment planning was computerized in 59 centers. The irradiation dose was prescribed at the ICRU point in 56 centers and portal films were made in 54 centers. Intraoperative radiotherapy was used in 4 centers: for partial breast irradiation in 1 and for boost administration in 3 centers. Although the quality of radiotherapy delivery has improved in Italy in recent years, approaches that do not conform to international standards persist.

Margin status of the surgical specimen has been shown to be a prognostic and risk factor for local recurrence in breast cancer surgery. It has been studied as a topic of intervention to diminish reoperation rates and reduce the probability of local recurrence in breast conservative surgery (BCS). This study aims to validate the Dutch BreastConservation! nomogram, created by Pleijhus et al., which predicts preoperative probability of positive margins in BCS. Patients with diagnosis of breast cancer stages cT1-2, who underwent BCS at the Breast Center of São João University Hospital (BC-CHSJ) in 2013-2014, were included. Association and correlation were evaluated for clinical, radiological, pathological and surgical variables. Multivariable logistic regression and ROC curves were used to assess nomogram parameters and discrimination. In our series of 253 patients, no associations were found between margin status and other studied variables (such as age or family history of breast cancer), except for weight (p-value = 0.045) and volume (p-value = 0.012) of the surgical specimen. Regarding the nomogram, a statistically significant association was shown between cN1 status and positive margins (p-value = 0.014). No differences were registered between the scores of patients with positive versus negative margins. Discrimination analysis showed an AUC of 0.474 for the basic and 0.508 for the expanded models. We cannot assume its external validation or its applicability to our cohort. Further studies are needed to determine the validity of this nomogram and achieve a broader view of currently available tools. Copyright © 2016 Elsevier Ltd. All rights reserved.

SUMMARY It has been suggested that a conservative trans-oral approach to proximal and hilo-parenchymal submandibular stones (HPSMS) is a valid alternative to the more frequently used sialadenectomy. The aim of this study was to evaluate the surgical, ultrasonographic and patients' subjective outcomes of results of the trans-oral removal of HPSMS. Between January 2003 and September 2015, sialendoscope-assisted trans-oral surgery was used to remove symptomatic, large (> 7 mm), fixed and palpable HPSMS from 479 patients under general anaesthesia. All patients were followed clinically and ultrasonographically to investigate symptom relief and recurrence of stones, and were telephonically interviewed to assess saliva-related subjective outcomes with a questionnaire. Stones were successfully removed from 472 patients (98.5%); the seven failures (1.5%) concerned pure parenchymal stones. One year after the procedure, 408 patients (85.1%) were symptom free, 59 (12.3%) had recurrent obstructive symptoms and 12 (2.6%) had recurrent infections. Of the 54 patients who developed a recurrent stone (11.2%), 52 underwent a second procedure: 29 interventional sialendoscopies, two sialendoscope-assisted intra-corporeal pneumatic lithotripsy, eight secondary transoral surgery to remove residual stones, six a cycle of extra-corporeal lithotripsy and seven submandibular sialadenectomy. Most patients (75.2%) reported mild surgery-related pain. The symptoms of 454 patients (94.8%) improved after adjunctive treatment and, at the end of follow-up, the affected gland was preserved in 98.5% of patients. A sialendoscope-assisted trans-oral removal of large HPSMS is a safe, effective, conservative surgical procedure, and functional preservation of the main duct and parenchyma of the obstructed gland allows sialendoscopic access through the natural ostium in case of recurrence. Combining a trans-oral approach with other minimally invasive, conservative procedures ensures symptomatic relief and salivary duct system clearance in the majority of patients. PMID:28516974

To the authors' knowledge, the survival benefit of local therapy in the setting of advanced prostate cancer remains unknown. The authors investigated whether prostate-directed treatment with either surgery or radiotherapy versus conservative treatment in the setting of locally advanced or metastatic disease was associated with improved survival within a cohort of men from the Centers for Disease Control and Prevention's (CDC) Breast and Prostate Cancer Data Quality and Patterns of Care Study (CDC POC-BP). Men diagnosed with locally advanced (cT3-T4 or N+ and M0) or metastatic prostate cancer were identified. The authors compared survival by treatment type, categorized as conservative (androgen deprivation therapy only) versus aggressive (radical prostatectomy or any type of radiotherapy). Nine-year overall survival and prostate cancer-specific survival were estimated using the Kaplan-Meier method. The Cox proportional hazards model was used to determine factors independently associated with 9-year prostate cancer-specific survival. For men with advanced, nonmetastatic prostate cancer, conservative treatment alone was associated with a 4 times higher likelihood of prostate cancer mortality compared with men treated with surgery (hazard ratio, 4.18; 95% confidence interval, 1.44-12.14). In contrast, no difference was found between conservative versus aggressive treatment after adjusting for covariates for men with metastatic disease. The 9-year prostate cancer-specific survival rate was 27% for those receiving aggressive treatment versus 24% for men undergoing conservative treatment. The authors did not observe a survival advantage with local therapy in addition to standard androgen deprivation therapy for men with metastatic prostate cancer. However, the results of the current study did affirm advantages in the setting of locally advanced disease. Aggressive local therapy in the setting of metastatic disease needs to be studied carefully before clinical adoption.

Primary gastric lymphoma (PGL) is the most common extranodal non-Hodgkin lymphoma. This retrospective study aimed to analyze the clinical characteristics, prognostic factors, and roles of different treatment modalities in patients with PGL.From January 2003 to November 2014, 165 patients who were diagnosed with PGL at West China Hospital were enrolled in this study. The clinical features, treatment, and follow-up information were analyzed.In this study, diffuse large B-cell lymphoma (DLBCL) (108, 65.5%) and mucosa-associated lymphoid tissue (MALT) lymphoma (52, 31.5%) were two predominant histological subtypes. One-year and 5-year overall survival (OS) rates of all patients were 95.2% and 79.5%, respectively; in whom 110 (66.7%) underwent surgery, 110 (66.7%) received chemotherapy, 12 (7.3%) received radiotherapy, and 10 (6.1%) received Helicobacter pylori eradication. And 75 patients (45.5%) were treated with at least 2 different types of therapies. Elevated lactic dehydrogenase (LDH) levels, poor performance status (PS), advanced stage, International Prognostic Index (IPI) score ≥3, conservative treatment, and high-grade histological subtype were associated with worse prognosis in univariate analysis. Cox regression analysis showed that LDH levels, PS, staging, and histological subtype were independent predictors of survival outcomes. In the DLBCL type, 5-year OS was significantly better in the surgically treated group (80.1%) than that of patients conservatively treated (49.8%) (P = 0.001). Surgical treatment had almost no impact on OS in the MALT type than conservative treatment (P = 0.597). The proportion of patients received conservative treatment increased from 4.5% in period 1 to 51.7% in period 4.High LDH levels, poor PS, advanced staging, and malignant pathological type at diagnosis are significantly associated with poor OS. Our data suggest that surgery is superior in prognosis over conservative treatment in the DLBCL type, but not in the MALT type. Recently, conservative treatment is becoming more preferred approach in patients with PGL.

The patient was a 64-year-old woman with no history of laryngeal disorders. She underwent video-assisted right lower lobectomy and node dissection for lung cancer. Using a stylet while the patient was under general anesthesia, tracheal intubation with a 35-French gauge left-sided double-lumen endobronchial tube was successfully performed on the first attempt. The patient developed slight hoarseness on postoperative day 1, and we initially suspected recurrent laryngeal nerve paralysis caused by the surgery, which we elected to treat conservatively. However, because her hoarseness had not improved 4 months after surgery, we evaluated her vocal cords using laryngoscopy. This revealed severe dysfunction of the right vocal cord and arytenoid dislocation, which we treated through reduction using a balloon catheter. By 6 months, the patient's vocal cord mobility had improved. Arytenoid dislocation is a rare complication, but should be suspected when patients have right vocal fold paralysis after lung cancer surgery.

Testicular benign tumors are very rare (< 5%). Testicular Angiofibroma (AF) is one of those, however the gold standard of treatment and follow-up is still unclear. A 47 years-old man with only one functioning testis was referred to our clinic for a palpable right testicular mass and atrophic contralateral testis. Patient underwent testis-sparing surgery with inguinal approach and intraoperative frozen sections examination with diagnosis of AF. Final histology confirmed AF. Post-operative follow-up was uneventful. Clinical and ultrasonographic follow-up was negative after 8 months. We report a conservative surgery in a patient with AF of the solitary testis. AF is a benign para-testicular fibrous neoplasm that could be misinterpreted as malignant tumor and treated with orchiectomy. Testis-sparing surgery is recommended in this case with intraoperative pathological examination. The excision of the mass is enough but in front of a possible recurrence a long follow-up is advisable.

Fertility sparing treatment in borderline ovarian tumours

Borderline ovarian tumours are low malignant potential tumours. They represent 10–15% of all epithelial ovarian malignancies. Patients with this type of tumour are younger at the time of diagnosis than patients with invasive ovarian cancer. Most of them are diagnosed in the early stages and have an excellent prognosis. It has been quite clearly established that the majority of borderline ovarian tumours should be managed with surgery alone. Because a high proportion of women with this malignancy are young and the prognosis is excellent, the preservation of fertility is an important issue in the management of these tumours. In this systemic review of the literature, we have evaluated in-depth oncological safety and reproductive outcomes in women with borderline ovarian tumours treated with fertility-sparing surgery, reviewing the indications, benefits, and disadvantages of each type of conservative surgery, as well as new alternative options to surgery to preserve fertility.

Linking Livelihoods and Conservation: An Examination of Local Residents' Perceived Linkages Between Conservation and Livelihood Benefits Around Nepal's Chitwan National Park

This paper investigates local recognition of the link between incentive-based program (IBP) benefits and conservation, and how perceptions of benefits and linkage influence attitudes in communities surrounding Chitwan National Park, Nepal. A survey of 189 households conducted between October and December 2004 examined local residents' perceived benefits, their attitudes toward park management, and perception of linkages between conservation and livelihoods. Linkage perceptions were measured by a scale compared with a respondent's recognition of benefits to determine whether IBPs establish a connection between benefits and livelihoods. An attitude scale was also created to compare attitudes toward park management with perceptions of benefits and linkage to determine if IBPs led to positive attitudes, and if the recognition of a direct tie between livelihoods and natural resources made attitudes more favorable. Research results indicate that as acknowledgement of benefit increases, so does the perception of linkage between the resource and livelihoods. Similarly, when perceived benefit increases, so too does attitude towards management. Positive attitude towards park management is influenced more by perception of livelihood dependence on resources than on benefits received from the park. However, overwhelming positive support voiced for conservation did not coincide with conduct. In spite of the positive attitudes and high perception of linkage, people did not necessarily behave in a way compatible with conservation. This suggests that while benefits alone can lead to positive attitudes, without clear linkages to conservation, the IBP may lose persuasion when alternative options—conflicting with conservation objectives—arise promising to provide greater economic benefit.

Improving management of small natural features on private lands by negotiating the science–policy boundary for Maine vernal pools

Vernal pools are far more important for providing ecosystem services than one would predict based on their small size. However, prevailing resource-management strategies are not effectively conserving pools and other small natural features on private lands. Solutions are complicated by tensions between private property and societal rights, uncertainties over resource location and function, diverse stakeholders, and fragmented regulatory authority. The development and testing of new conservation approaches that link scientific knowledge, stakeholder decision-making, and conservation outcomes are important responses to this conservation dilemma. Drawing from a 15-y history of vernal pool conservation efforts in Maine, we describe the coevolution of pool conservation and research approaches, focusing on how research-based knowledge was produced and used in support of management decisions. As management shifted from reactive, top-down approaches to proactive and flexible approaches, research shifted from an ecology-focused program to an interdisciplinary program based on social–ecological systems. The most effective strategies for linking scientific knowledge with action changed as the decision-makers, knowledge needs, and context for vernal pool management advanced. Interactions among stakeholders increased the extent to which knowledge was coproduced and shifted the objective of stakeholder engagement from outreach to research collaboration and development of innovative conservation approaches. New conservation strategies were possible because of the flexible, solutions-oriented collaborations and trust between scientists and decision-makers (fostered over 15 y) and interdisciplinary, engaged research. Solutions to the dilemma of conserving small natural features on private lands, and analogous sustainability science challenges, will benefit from repeated negotiations of the science–policy boundary.

The authors present results of surgical treatment of cervical spine degenerative disease via Implaspin biotitanium replacement. Surgery was indicated for a group of 24 patients with symptoms of cervical spondylogenic myelopathy or the irritation decay root syndrome non-reacting to conservative treatment. Pre-surgery X-ray and MRI examinations showed spinal canal stenosis caused by the intervertebral disk osteochondrosis combined with prolapse or dorsal osteophytes. Clinical problems of the group of patients were evaluated through the JOA classification before surgery and during the 2nd, the 6th and month 12th after surgery. The surgery rate of success was evaluated in percentages during post-surgery examinations that took place in the 12th month. Based on the JOA classification, that rate of success falls into the good surgery results zone. The post-surgery X-ray examinations showed two sank replacements by 1/3 of its height into the surrounding vertebral bodies. In these cases we performed the control MRI. No signs of the new spinal compression were found and the spinal canal was free in the operated site. Based on our short-term experiences, the Implaspin bioactive replacement seems to be a suitable alternative to the other types of replacements designed for intervertebral fusion in the lower cervical spine area.

Hand surgeons need continuing professional development due to rapid advancement in the field. Traditional approaches have proven to be challenging due to the nature of surgical practice and other demands. Social media sites have shown the potential to build an online community of practice. One of the authors (VR) started Hand Surgery International on LinkedIn in February 2011. The number of members increased from 38 in the beginning to 4106 members by August 13, 2015, with members from all over the world. Half of them are from plastic surgery, with 16.8% hand and 17.8% orthopedic surgery; 63.8% of them are consultants. There were 151 discussion topics, which generated 1238 comments at an average of 8.2 comments per discussion thread. The topics focused on management of difficult patients, seeking consensus, and searching information. The features participants found most useful included case-based discussion, polls/surveys, and network opportunity. Members perceived the LinkedIn community as user-friendly and easy to use. It does not require significant technical knowledge. For the question "How would you rate the overall ease of using this platform?" 42% answered "strongly agree" and 37% "agree". The LinkedIn group serves as an effective means for continuing professional development for hand surgeons. © 2015 The Alliance for Continuing Education in the Health Professions, the Society for Academic Continuing Medical Education, and the Council on Continuing Medical Education, Association for Hospital Medical Education.

Management of failed rotator cuff repair: a systematic review

Importance Recurrent tear after rotator cuff repair (RCR) is common. Conservative, and open and arthroscopic revisions, have been advocated to treat these failures. Aim or objective The purpose of this systematic review was to evaluate the different options for managing recurrent rotator cuff tears. Evidence review A search was conducted of level I through 4 studies from January 2000 to October 2015, to identify studies reporting on failed RCR. 10 articles were identified. The overall quality of evidence was very low. Findings Mid-term to long-term follow-up of patients treated conservatively revealed acceptable results; a persistent defect is a well-tolerated condition that only occasionally requires subsequent surgery. Conservative treatment might be indicated in most patients, particularly in case of posterosuperior involvement and poor preoperative range of motion. Revision surgery might be indicated in a young patient with a repairable lesion, a 3 tendon tear, and in those with involvement of the subscapularis. Conclusions and relevance The current review indicates that arthroscopic revision RCR can lead to improvement in functional outcome despite a high retear rate. Further studies are needed to develop specific rehabilitation in the case of primary rotator cuff failure, to better understand the place of each treatment option, and, in case of repair, to optimise tendon healing.

Barlow, Susan J

2016-12-01

The current literature contains no reports of treatment options other than surgery following failed conservative management of a triangular fibrocartilage complex (TFCC) tear. The purpose of this study is to describe the use of a novel brace as a non-surgical intervention for TFCC tears. This paper is a case study of a subject with a magnetic resonance imaging-confirmed TFCC tear. As an alternative to surgery, he consented to wear a novel brace for 12 weeks after conservative management of his injury had failed. His recovery from injury was monitored with a weight-bearing tolerance test and the disabilities of the arm, shoulder and hand (DASH) outcome measure. An increase in weight-bearing tolerance and upper extremity use was evident immediately after donning the brace. After 12 weeks, the subject demonstrated a return to normal weight-bearing tolerance and normal DASH outcome measure scores. These improvements were still evident at a 1-year follow-up appointment. Utilizing this novel brace resulted in functional status improvement in a subject with a TFCC tear as demonstrated by significant changes in his DASH outcome measure scores. This case study demonstrates the first non-surgical alternative treatment for a TFCC tear after conservative management has failed. Copyright © 2016 John Wiley & Sons, Ltd.

Background Obesity seems to be linked to the hypothalamic involvement in craniopharyngioma. We evaluated the pre-surgery relationship between the degree of this involvement on magnetic resonance imaging and insulin resistance, as evaluated by the homeostasis model insulin resistance index (HOMA). As insulin-like growth factor 1, leptin, soluble leptin receptor (sOB-R) and ghrelin may also be involved, we compared their plasma concentrations and their link to weight change. Methods 27 children with craniopharyngioma were classified as either grade 0 (n = 7, no hypothalamic involvement), grade 1 (n = 8, compression without involvement), or grade 2 (n = 12, severe involvement). Results Despite having similar body mass indexes (BMI), the grade 2 patients had higher glucose, insulin and HOMA before surgery than the grade 0 (P = 0.02, <0.05 and 0.02 respectively) and 1 patients (P < 0.02 and <0.03 for both insulin and HOMA). The grade 0 (5.8 ± 4.9) and 1 (7.2 ± 5.3) patients gained significantly less weight (kg) during the year after surgery than did the grade 2 (16.3 ± 7.4) patients. The pre-surgery HOMA was positively correlated with these weight changes (P < 0.03). The data for the whole population before and 6–18 months after surgery showed increases in BMI (P < 0.0001), insulin (P < 0.005), and leptin (P = 0.0005), and decreases in sOB-R (P < 0.04) and ghrelin (P < 0.03). Conclusion The hypothalamic involvement by the craniopharyngioma before surgery seems to determine the degree of insulin resistance, regardless of the BMI. The pre-surgery HOMA values were correlated with the post-surgery weight gain. This suggests that obesity should be prevented by reducing inn secretion in those cases with hypothalamic involvement.

Melorheostosis is a rare disease that usually burdens the patient with painful disability or soft tissue compromise. The treatment is usually symptomatic and conservative. Patients with severe and complicated forms of the disease may require surgery. Involvement of the distal part of a limb usually carries more morbidity, such as tumefaction pain, cosmetic and psychosocial or functional problems that render conservative treatment unsatisfactory to patients. In our series, surgical debulking or decompression of the mass effect provided prompt symptom relief. Copyright © 2012. Published by Elsevier B.V.

Diffusion of breast conserving surgery in medical communities.

PubMed

Jerome-D'Emilia, Bonnie; Begun, James W

2005-01-01

Excluding skin cancers, breast cancer is the most common form of cancer in women. Due to an increased focus on early detection, many more cases of breast cancer are now diagnosed at an early stage, which makes the use of breast conserving surgery (BCS) an efficacious and often more desirable treatment choice than mastectomy. An analysis of the variation in the use of BCS in the United States was performed using data from the years 1988 and 1994, and stratifying hospitals on the basis of teaching status. In both 1988 and 1994, BCS was highest in academic teaching hospitals and lowest in community hospitals. This finding is interpreted within the framework of classical diffusion theory. Social and cultural norms in local medical communities have a strong effect on the degree to which innovations diffuse rapidly or not. This analysis is useful in the understanding of geographic and hospital-based variations in treatment for early stage breast cancer and other illnesses that have long and strongly held traditions of treatment.

Introduction: Bacterial infection of endovascular stent grafts is a serious condition, regularly leading to graft replacement by open bypass surgery.Case ReportWe describe the case of a staphylococcal infection of a 150-mm covered stent graft (Gore Viabahn), placed in the superficial femoral artery. Stent graft infection was successfully treated by oral administration of penicillinase-resistant flucloxacillin and the lipopeptide daptomycin with complete graft preservation, not requiring surgical treatment. During 1-year follow-up, the graft infection did not reappear. However, the patient developed restenosis at the proximal margin of the stent with recurrence of mild claudication, so far treated conservatively. Conclusion: With the increasedmore » use of covered stent grafts in the peripheral vasculature, the frequency of graft infection will increase. We demonstrate that with newly developed antibiotics, it is possible to treat this severe complication conservatively, with complete graft preservation and without the need for bypass surgery in selected cases.« less

Colonic casts: unexpected complications of colonic ischaemia.

Introduction Extensive colonic ischaemia can result in passage of a colonic 'cast' (CC) through the rectum. Case Study We report a 69-year-old male who initially underwent surgery to remove a sessile polyp. On postoperative day (POD)15, he was febrile, suffering from diarrhoea, and was treated conservatively. On POD18, the patient returned to our hospital with a CC that presented after defaecation. Computed tomography of the abdomen revealed a CC extending from the descending colon to the anal orifice with presentation of air between the affected colonic wall and the CC. The patient was treated conservatively and discharged on POD20 without complications having passed the CC (≈80cm) completely and becoming afebrile. Conclusions In most cases, the cause of CC passage is surgery for colorectal cancer or repair of an abdominal aortic aneurysm. A mild-to-severe presentation is dependent upon the bowel-wall layers affected by ischaemia and which therefore are included in the CC.

Pulmonary suture abscess with false-positive 18F-fluorodeoxyglucose positron emission scan mimicking lung cancer recurrence.

We present the case of a 57-year-old woman with pulmonary suture abscess. She had undergone right S3 segmentectomy for early lung adenocarcinoma 7 years before and right breast-conserving surgery for invasive ductal carcinoma 5 months previously, followed by irradiation plus endocrine therapy. Chest radiography and computed tomography revealed an irregular mass (3.5 cm in diameter) between the residual S1 segment and the middle lobe, neighboring the staple line of the segmentectomy. 18F-fluorodeoxyglucose uptake into the mass increased, seen by positron emission scans. Therefore, we could not rule out the possibility of local recurrence of lung cancer and resected it. Pathologically and microbiologically, the mass was a suture abscess arising around the nylon suture of the previous segmentectomy. This lesion was the result of a foreign-body reaction, as confirmed by polarized microscopy. Moreover, titanium staples at the segmentectomy and breast-conserving surgery may also have contributed to this condition.

Patients with traumatic non-iatrogenic intrathoracic tracheobronchial injuries managed in 2 tertiary centers in Saudi Arabia between 2000 and 2012, were studied. Clinical presentation, diagnostic evaluation, management, and outcome were reviewed. 78 patients with tracheobronchial injuries were included in this study. They were divided into 2 groups according to the management strategy. Forty-seven patients who were managed conservatively, and 31 underwent surgery. Surgery allowed shorter intensive care unit and hospital stays; otherwise, the results were comparable between the two groups. Early recognition and expedient appropriate management are essential in these potentially lethal injuries. Operative management can be achieved with acceptable mortality, and conservative treatment should be considered as a valuable alternative to the well-established surgical treatment. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Cardiovascular disease is the leading cause of death worldwide and patients with severe symptoms undergo cardiac surgery. Even after uncomplicated surgeries, some patients experience postoperative complications such as lung injury. We hypothesized that the procedure elicits metabolic activity that can be related to the disease progression, which is commonly observed two-three days postoperatively. More than 700 blood samples were collected from 50 patients at nine time points pre-, intra-, and postoperatively. Dramatic metabolite shifts were observed during and immediately after the intervention. Prolonged surgical stress was linked to an augmented anaerobic environment. Time series analysis showed shifts in purine-, nicotinic acid-, tyrosine-, hyaluronic acid-, ketone-, fatty acid, and lipid metabolism. A characteristic ‘metabolic biosignature’ was identified correlating with the risk of developing postoperative complications two days before the first clinical signs of lung injury. Hence, this study demonstrates the link between intra- and postoperative time-dependent metabolite changes and later postoperative outcome. In addition, the results indicate that metabotyping patients’ journeys early, during or just after the end of surgery, may have potential impact in hospitals for the early diagnosis of postoperative lung injury, and for the monitoring of therapeutics targeting disease progression.

Assenza, M; De Gruttola, I; Rossi, D; Castaldi, S; Falaschi, F; Giuliano, G

2016-01-01

Adhesions small bowel obstructions (aSBO) are among the leading causes of emergency operative intervention. About the 80% of aSBO cases resolve without a surgical treatment. It's important to identify which patients could undergo a conservative treatment to prevent an useless surgery The aim of this study is to determine findings that can indicate whether patients with aSBO should undergo a conservative or a surgical treatment. 313 patients with diagnosis of submission of aSBO were restudied. Patients were divided into two groups based on the different type of treatment received, 225 patients who underwent surgical treatment within 24 hours after admission, 88 patients which underwent conservative treatment successfully. For each patient, clinical, hematochemical and radiological findings have been analysed. The treatment of aSBO should be, at the beginning, conservative except that cases that presents clinical and/or CT-scan findings predictive for a surgical treatment (free peritoneal fluid, mesenterial edema, transitional point) or a peritonitis (pneumatosis intestinalis, pneumoperitoneum).

Quality of governance and effectiveness of protected areas: crucial concepts for conservation planning.

PubMed

Eklund, Johanna; Cabeza, Mar

2017-07-01

Protected areas (PAs) are a key tool for biodiversity conservation and play a central role in the Convention on Biological Diversity. Recently, the effectiveness of PAs has been questioned, and assessing how effective they are in enabling the future persistence of biodiversity is not trivial. Here, we focus on terrestrial PAs and clarify the terminology related to PA effectiveness, distinguishing between management and ecological aspects. We suggest that the quality of governance affects both aspects of effectiveness but recognize a lack of synthetic understanding of the topic. We present a conceptual framework linking the underlying mechanisms by which the quality of governance affects conservation outcomes in PAs and how this relates to conservation planning. We show that it is crucial to separate pressure and response and how these together will lead to the observed conservation outcomes. We urge for more focused attention on governance factors and in particular more empirical research on how to address causality and how to account for the quality of governance when prioritizing actions. Our framework is linked to the classic concepts of systematic conservation planning and clarifies the strategies available to achieve a comprehensive and effective network of PAs. © 2016 The Authors.

A global outbreak of invasive Mycobacterium chimaera infections after cardiac surgery has recently been linked to bioaerosols from contaminated heater-cooler units. The majority of cases have occurred after valvular surgery or aortic graft surgery and nearly half have resulted in death. To date, infections in patients with left ventricular assist devices (LVADs) have not been characterized in the literature. We report two cases of device-associated M. chimaera infection in patients with continuous-flow LVADs and describe challenges related to diagnosis and management in this population. © 2017 Wiley Periodicals, Inc.

To predict who will undergo midurethral sling surgery (surgery) after initial pelvic floor muscle training (physiotherapy) for stress urinary incontinence in women. This was a cohort study including women with moderate to severe stress incontinence who were allocated to the physiotherapy arm from a previously reported multicentre trial comparing initial surgery or initial physiotherapy in treating stress urinary incontinence. Crossover to surgery was allowed. Data from 198/230 women who were randomized to physiotherapy was available for analysis, of whom 97/198 (49 %) crossed over to surgery. Prognostic factors for undergoing surgery after physiotherapy were age <55 years at baseline (OR 2.87; 95 % CI 1.30-6.32), higher educational level (OR 3.28; 95 % CI 0.80-13.47), severe incontinence at baseline according to the Sandvik index (OR 1.77; 95 % CI 0.95-3.29) and Urogenital Distress Inventory; incontinence domain score (OR 1.03; per point; 95 % CI 1.01-1.65). Furthermore, there was interaction between age <55 years and higher educational level (OR 0.09; 95 % CI 0.02-0.46). Using these variables we constructed a prediction rule to estimate the risk of surgery after initial physiotherapy. In women with moderate to severe stress incontinence, individual prediction for surgery after initial physiotherapy is possible, thus enabling shared decision making for the choice between initial conservative or invasive management of stress urinary incontinence.

A conceptual model to facilitate amphibian conservation in the northern Great Plains

Mushnet, David M.; Euliss, Ned H.; Stockwell, Craig A.

2012-01-01

As pressures on agricultural landscapes to meet worldwide resource needs increase, amphibian populations face numerous threats including habitat destruction, chemical contaminants, disease outbreaks, wetland sedimentation, and synergistic effects of these perturbations. To facilitate conservation planning, we developed a conceptual model depicting elements critical for amphibian conservation in the northern Great Plains. First, we linked upland, wetland, and landscape features to specific ecological attributes. Ecological attributes included adult survival; reproduction and survival to metamorphosis; and successful dispersal and recolonization. Second, we linked ecosystem drivers, ecosystem stressors, and ecological effects of the region to each ecological attribute. Lastly, we summarized information on these ecological attributes and the drivers, stressors, and effects that work in concert to influence the maintenance of viable and genetically diverse amphibian populations in the northern Great Plains. While our focus was on the northern Great Plains, our conceptual model can be tailored to other geographic regions and taxa.

Defining probabilities of bowel resection in deep endometriosis of the rectum: Prediction with preoperative magnetic resonance imaging.

2018-02-01

Deep endometriosis of the rectum is a highly challenging disease, and a surgical approach is often needed to restore anatomy and function. Two kinds of surgeries may be performed: radical with segmental bowel resection or conservative without resection. Most patients undergo magnetic resonance imaging (MRI) before surgery, but there is currently no method to predict if conservative surgery is feasible or whether bowel resection is required. The aim of this study was to create an algorithm that could predict bowel resection using MRI images, that was easy to apply and could be useful in a clinical setting, in order to adequately discuss informed consent with the patient and plan the an appropriate and efficient surgical session. We collected medical records from 2010 to 2016 and reviewed the MRI results of 52 patients to detect any parameters that could predict bowel resection. Parameters that were reproducible and with a significant correlation to radical surgery were investigated by statistical regression and combined in an algorithm to give the best prediction of resection. The calculation of two parameters in MRI, impact angle and lesion size, and their use in a mathematical algorithm permit us to predict bowel resection with a positive predictive value of 87% and a negative predictive value of 83%. MRI could be of value in predicting the need for bowel resection in deep endometriosis of the rectum. Further research is required to assess the possibility of a wider application of this algorithm outside our single-center study. © 2017 Japan Society of Obstetrics and Gynecology.

Objectives. To describe conservative and surgical foot care in patients with RA in England and explore factors that predict the type of foot care received. Methods. Use of podiatry and type of foot surgery were outcomes recorded in an inception cohort involving nine rheumatology centres that recruited patients with RA between 1986 and 1998 across England. Associations between patient-specific factors and service use were identified using univariate logistic regression analyses. The independence of these associations was then verified through multiple binary logistic regression modelling. Results. Data were collected on 1237 patients with RA [66.9% females, mean (s.d.) age at disease onset = 54.36 (14.18) years, median DAS = 4.09 (1st quartile = 3.04, 3rd quartile = 5.26), median HAQ = 1 (0.50, 1.63)]. Interventions involving the feet in the cohort were low with only 364 (30%) out of 1218 receiving podiatry and 47 (4%) out of 1237 patients having surgery. At baseline, female gender, increasing age at onset, being RF positive and higher DAS scores were each independently associated with increased odds of seeing a podiatrist. Gender, age of onset and baseline DAS were independently associated with the odds of having foot surgery. Conclusions. Despite the known high prevalence of foot pathologies in RA, only one-third of this cohort accessed podiatry. While older females were more likely to access podiatry care and younger patients surgery, the majority of the RA population did not access any foot care. PMID:21504991

Conservative Treatment of Ankle Osteoarthritis: Can Platelet-Rich Plasma Effectively Postpone Surgery?

PubMed

Repetto, Ilaria; Biti, Besmir; Cerruti, Paola; Trentini, Roberto; Felli, Lamberto

Osteoarthritis is the most common and disabling of the orthopedic diseases. Currently, the conservative treatment of osteoarthritis is limited to symptomatic treatment, whose goal is to improve function and pain control. Ankle osteoarthritis is relatively uncommon, in contrast to osteoarthritis of the hip and knee, and the therapeutic options (both pharmacologic and surgical) are limited, with surgery providing poorer and less predictable results. The effectiveness of platelet-rich plasma injections for osteoarthritis is still controversial, especially so for ankle arthritis, owing to the lack of evidence in the present data. We retrospectively evaluated the mid- to long-term clinical results (mean follow-up of 17.7 months) for platelet-rich plasma injections in 20 patients (20 ankles) with ankle osteoarthritis. We evaluated the presence of pain using the visual analog scale, function using the Foot and Ankle Disability Index, and subjective satisfaction. The pre- and post-treatment scores, obtained from the clinical records and from telephone interviews during the follow-up period, were compared using the Student t test. We found a strong positive effect for 4 platelet-rich plasma injections (injected once a week) on pain (p = .0001) and function (p = .001), with 80% of patients very satisfied and satisfied, and only 2 patients (10%) required surgery because of early treatment failure. These results suggest that the use of platelet-rich plasma injection is a valid and safe alternative to postpone the need for surgery. Copyright © 2016 American College of Foot and Ankle Surgeons.

Carpal Tunnel Syndrome: Physical Therapy or Surgery?

PubMed

2017-03-01

Carpal tunnel syndrome causes pain, numbness, and weakness in the wrist and hand. Nearly 50% of all work-related injuries are linked to carpal tunnel syndrome, and people with this injury are more likely to miss work because of it. Patients with carpal tunnel syndrome can be treated with physical therapy or surgery. Although surgery may be considered when the symptoms are severe, more than a third of patients do not return to work within 8 weeks after an operation. Based on the potential side effects and risks of surgery, patients often ask if they might try physical therapy first. An article in the March 2017 issue of JOSPT assesses the effectiveness of therapy and surgery to treat carpal tunnel syndrome. J Orthop Sports Phys Ther 2017;47(3):162. doi:10.2519/jospt.2017.0503.

Literature about long implants used together with a minimally invasive spine surgery (MISS) technique is scarce. Our objective is to contribute our surgical experience in this field and to specifically focus on several technical details. A digitally-dissected canal along the paravertebral muscles was created linking the stab wounds on each side in relation with the pedicles to be cannulated. Screws were inserted following the percutaneous technique. Long rods were modelled, threaded through the extender sleeves along the paravertebral canal and pushed into the screw heads with the reduction forceps. When fusion was needed, the facet complex was decorticated with a drill. To insert a cross-link, a canal between the 2 rods was digitally created and the spinous process was drilled. 8 patients underwent surgery (age range: 25-77 years). Indications were postosteomyelitis kyphosis in 3 patients, bone tumor in 3, and spine fracture in 2. No blood transfusions were necessary during or after surgery. A cross-link was inserted in 2 patients. Posterolateral bone fusion was attempted in 4, but radiologically identifiable in none. In one patient a cantilever manoeuvre was done to correct kyphosis. Mean duration of surgery was 4 h. There were no clinical complications related to the operation or the hardware (mean follow-up of 7.14 months, range: 1-15 months). The application of MISS techniques can be broadened to long spinal constructs to assess fractures, tumors or deformity, especially in elderly or debilitated patients. Nevertheless, posterolateral fusion is still a challenge through these limited exposures. © Georg Thieme Verlag KG Stuttgart · New York.

Resource managers are increasingly tasked with developing habitat conservation plans in the face of numerous, sometimes competing, objectives. These plans must often be implemented across dispersed habitat conservation units that may contribute unequally to overall conservation objectives. Using U.S. Fish and Wildlife Service waterfowl production areas (WPA) in western Minnesota as our conservation landscape, we develop a landscape-scale approach for evaluating the conservation value of dispersed habitat conservation units with multiple conservation priorities. We evaluated conservation value based on a suite of variables directly applicable to conservation management practices, thus providing a direct link between conservation actions and outcomes. We developed spatial models specific to each of these conservation objectives and also developed two freely available prioritization tools to implement these analyses. We found that some WPAs provided high conservation value across a range of conservation objectives, suggesting that managing these specific areas would achieve multiple conservation goals. Conversely, other WPAs provided low conservation value for some objectives, suggesting they would be most effectively managed for a distinct set of specific conservation goals. Approaches such as ours provide a direct means of assessing the conservation value of dispersed habitat conservation units and could be useful in the development of habitat management plans, particularly when faced with multiple conservation objectives.

Clinical effectiveness and cost-effectiveness of treatments for patients with chronic pain.

PubMed

Turk, Dennis C

2002-01-01

Chronic pain is a prevalent and costly problem. This review addresses the question of the clinical effectiveness and cost-effectiveness of the most common treatments for patients with chronic pain. Representative published studies that evaluate the clinical effectiveness of pharmacological treatments, conservative (standard) care, surgery, spinal cord stimulators, implantable drug delivery systems (IDDSs), and pain rehabilitation programs (PRPs) are examined and compared. The cost-effectiveness of these treatment approaches is also considered. Outcome criteria including pain reduction, medication use, health care consumption, functional activities, and closure of disability compensation cases are examined. In addition to clinical effectiveness, the cost-effectiveness of PRPs, conservative care, surgery, spinal cord stimulators, and IDDSs are compared using costs to return a treated patient to work to illustrate the relative expenses for each of these treatments. There are limitations to the success of all the available treatments. The author urges caution in interpreting the results, particularly in comparisons between treatments and across studies, because there are broad differences in the pain syndromes and inclusion criteria used, the drug dosages, comparability of treatments, the definition of "chronic" used, the outcome criteria selected to determine success, and societal differences. None of the currently available treatments eliminates pain for the majority of patients. Pain rehabilitation programs provide comparable reduction in pain to alternative pain treatment modalities, but with significantly better outcomes for medication use, health care utilization, functional activities, return to work, closure of disability claims, and with substantially fewer iatrogenic consequences and adverse events. Surgery, spinal cord stimulators, and IDDSs appear to have substantial benefits on some outcome criteria for carefully selected patients. These modalities are, however, expensive. Pain rehabilitation programs are significantly more cost effective than implantation of spinal cord stimulators, IDDSs, conservative care, and surgery, even for selected patients. Research is needed to identify which patients are most likely to benefit from the available treatments and to study combinations of the available treatments since none of them appear capable of eliminating pain or significantly improving functional outcomes for all treated.

[Phoniatric surgery and conservative treatment of vocal cord hematoma].

PubMed

Milutinović, Z

Functional-traumatic lesions of the vocal fold include mucous stranding, "nodular" lesions, polyps, cysts, contact hyperplasia and haematoma of the vocal fold. An acute voice overuse may result in bleeding (haematoma) within the vocal fold. This may be in the form of petechial bleeding, or a genuine haematoma develops within the tissues of the vocal fold. Haematoma may also arise as a consequence of prolonged cough, forceful vomiting, lifting of a heavy weight, various effortful activities, etc. Haematoma is usually located close to the vocal fold free edge and therefore disturbs the glottic closure during phonation. The treatment is adapted to the size and localization of haematoma, as well as to the time elapsed from onset of the lesion. Phonosurgery can be used in therapy, as well as corticosteroid treatment. A series of 102 vocal fold haematomas has been treated by phonosurgery (39) and conservative therapy (63). Phonosurgical interventions were performed by an indirect approach, by use of microstroboscopy (28 patients) and videostroboscopy (11 causes). Conservative treatment consisted of corticosteroid therapy. During a 10-year period 1550 phonosurgical operations were performed for benign lesions of the vocal fold, including 39 haematomas (2.5%). It was established that recovery of vibration pattern was significantly faster in the surgery group in comparison to the group of patients treated conservatively. All surgical patients were operated within the first several days after the onset of symptoms. In case of a vocal fold haematoma, it is very important to establish the diagnosis as soon as possible in order to start with the therapy early enough. Within the first several days after the onset (the best within 24-48 hours) a phonosurgical treatment is indicated, preferably by the use of indirect videostroboscopy. If the treatment is started later we use corticoids. However, the results are inferior as compared to surgery. We did not perform direct microlaryngoscopy in these cases, for a lack of function monitoring and possible local trauma to the tissues. In the majority of cases the voice therapy is required as well.

Economic and Social Political Ideology and Homophobia: The Mediating Role of Binding and Individualizing Moral Foundations.

Barnett, Michael D; Öz, Haluk C M; Marsden, Arthur D

2018-05-01

Previous research has linked conservative political ideology with homophobia. Political ideology has also been linked to differences in moral decision-making, with research suggesting that conservatives and liberals may use different values in their moral decision-making processes. Moral foundations theory is a model of moral decision-making that proposes that individuals emphasize different domains in moral decision-making. Conservatives tend to emphasize binding foundations, while liberals tend to emphasize individualizing foundations. Utilizing large, ethnically diverse college samples, the purpose of these two cross-sectional studies (Study 1 N = 492; Study 2 N = 861) was to explore whether moral foundations mediate the relationship between political ideology and homophobia. These studies explored economic and social political ideology separately and utilized a two-factor model of moral foundations theory (individualizing and binding foundations). Results of both studies found that conservative economic and social political ideology was positively associated with homophobia. Study 1 found that both conservative economic and social political ideology had an indirect effect on homophobia through binding foundations. Study 2 found that both economic and social political ideology had an indirect effect on homophobia through both binding and individualizing foundations. Overall, the results were consistent with the notion that moral foundations may explain the relationship between political ideology and homophobia.

At first presentation of paediatric humeral lateral condyle fractures, radiological methods such as computerised tomography, ultrasonography, magnetic resonance imaging, arthrography, and internal oblique radiography are used to determine stability. Very few studies show which radiological method should be used to evaluate displacement at follow-up for conservatively treated patients. This study aimed to show that internal oblique radiography is a simple, effective method to determine the subsequent development of fracture displacement in patients with an initially non-displaced or minimally displaced fracture. In this retrospective study, 27 paediatric patients with non-displaced or minimally displaced (<2 mm) humerus lateral condyle fracture were evaluated by elbow anteroposterior radiograph. The degree of fracture displacement was evaluated by anteroposterior then by internal oblique radiographs. The first follow-up was made between the 5th and 8th day and thereafter at intervals of 7-10 days. Of the 27 patients identified with non-displaced or minimally displaced (<2 mm) fracture from the initial anteroposterior radiograph, 16 were accepted as displacement >2 mm as a result of the evaluation of the internal oblique radiography and underwent surgery. At follow-up, 2 of 11 patients were defined with displacement from anteroposterior and internal oblique radiographs and 4 from the internal oblique radiographs and underwent surgery. Conservative treatment was applied to 5 patients. Internal oblique radiography is the best imaging showing subsequent fracture displacement in initially non-displaced or minimally displaced humerus lateral condyle fractures. At the first week follow-up, anteroposterior and particularly internal oblique radiographs should be taken of conservatively treated patients.

Conservation Evo-Devo: Preserving Biodiversity by Understanding Its Origins.

Campbell, Calum S; Adams, Colin E; Bean, Colin W; Parsons, Kevin J

2017-10-01

Unprecedented rates of species extinction increase the urgency for effective conservation biology management practices. Thus, any improvements in practice are vital and we suggest that conservation can be enhanced through recent advances in evolutionary biology, specifically advances put forward by evolutionary developmental biology (i.e., evo-devo). There are strong overlapping conceptual links between conservation and evo-devo whereby both fields focus on evolutionary potential. In particular, benefits to conservation can be derived from some of the main areas of evo-devo research, namely phenotypic plasticity, modularity and integration, and mechanistic investigations of the precise developmental and genetic processes that determine phenotypes. Using examples we outline how evo-devo can expand into conservation biology, an opportunity which holds great promise for advancing both fields. Copyright © 2017 Elsevier Ltd. All rights reserved.

To determine if endophthalmitis following cataract surgery is linked to increased mortality. Increased mortality has been linked to patients with cataract and cataract surgery. We tested the hypothesis that post-cataract endophthalmitis has a greater risk of death than pseudophakes who do not develop this complication. Case-control study conducted in a tertiary public hospital. The study group comprised 50 consecutive patients with post-cataract endophthalmitis, and these were matched with selected controls. Patients with endophthalmitis following cataract surgery were identified from a prospective electronic surgical database. Subsequently, it was determined if the patient was deceased at the time of sequestration (September 2015), and the date of death was recorded. A previously described population who had undergone cataract surgery in the same facility was selected as a control group, and the population was case-matched in terms age, gender, presence or absence of diabetes and/or hypertension. The median survival rates were determined for the control group and the patients with post-cataract endophthalmitis. Fifty patients were identified as undergoing endophthalmitis post-cataract surgery, and 48 (n = 48) met inclusion criteria (mean age 72 years ±12 SD with 30:18 F:M); 17% were diabetic, and 50% had systemic hypertension. No statistically significant difference in median survival between the study and control cases was identified (100 months (95% confidence interval 86-114) vs. 106 months (95% confidence interval 66-146), respectively, P = 0.756). Post-cataract endophthalmitis was not associated with an increased rate of mortality in this study. © 2018 Royal Australian and New Zealand College of Ophthalmologists.

Epilepsy neurosurgery is a treatment option for children with refractory epilepsy. Our aim was to determine if outcomes improved over time. Pediatric epilepsy surgery patients operated in the first 11 years (1986-1997; pre-1997) were compared with the second 11 years (1998-2008; post-1997) for differences in presurgical and postsurgical variables. Despite similarities in seizure frequency, age at seizure onset, and age at surgery, the post-1997 series had more lobar/focal and fewer multilobar resections, and more patients with tuberous sclerosis complex and fewer cases of nonspecific gliosis compared with the pre-1997 group. Fewer cases had intracranial EEG studies in the post-1997 (0.8%) compared with the pre-1997 group (9%). Compared with the pre-1997 group, the post-1997 series had more seizure-free patients at 0.5 (83%, +16%), 1 (81%, +18%), 2 (77%, +19%), and 5 (74%, +29%) years, and more seizure-free patients were on medications at 0.5 (97%, +6%), 1 (88%, +9%), and 2 (76%, +29%), but not 5 (64%, +8%) years after surgery. There were fewer complications and reoperations in the post-1997 series compared with the pre-1997 group. Logistic regression identified post-1997 series and less aggressive medication withdrawal as the main predictors of becoming seizure-free 2 years after surgery. Improved technology and surgical procedures along with changes in clinical practice were likely factors linked with enhanced and sustained seizure-free outcomes in the post-1997 series. These findings support the general concept that clearer identification of lesions and complete resection are linked with better outcomes in pediatric epilepsy surgery patients.

A Symplectic Instanton Homology via Traceless Character Varieties

NASA Astrophysics Data System (ADS)

Horton, Henry T.

Since its inception, Floer homology has been an important tool in low-dimensional topology. Floer theoretic invariants of 3-manifolds tend to be either gauge theoretic or symplecto-geometric in nature, and there is a general philosophy that each gauge theoretic Floer homology should have a corresponding symplectic Floer homology and vice-versa. In this thesis, we construct a Lagrangian Floer invariant for any closed, oriented 3-manifold Y (called the symplectic instanton homology of Y and denoted SI(Y)) which is conjecturally equivalent to a Floer homology defined using a certain variant of Yang-Mills gauge theory. The crucial ingredient for defining SI( Y) is the use of traceless character varieties in the symplectic setting, which allow us to avoid the debilitating technical hurdles present when one attempts to define a symplectic version of instanton Floer homologies. Floer theories are also expected to roughly satisfy the axioms of a topological quantum field theory (TQFT), and furthermore Dehn surgeries on knots should induce exact triangles of Floer homologies. Following a strategy used by Ozsvath and Szabo in the context of Heegaard Floer homology, we prove that our theory is functorial with respect to connected 4-dimensional cobordisms, so that cobordisms induce homomorphisms between symplectic instanton homologies. By studying the effect of Dehn surgeries on traceless character varieties, we establish a surgery exact triangle using work of Seidel that relates the geometry of Lefschetz fibrations with exact triangles in Lagrangian Floer theory. We further prove that Dehn surgeries on a link L in a 3-manifold Y induce a spectral sequence of symplectic instanton homologies - the E2-page is isomorphic to a direct sum of symplectic instanton homologies of all possible combinations of 0- and 1-surgeries on the components of L, and the spectral sequence converges to SI(Y). For the branched double cover Sigma(L) of a link L in S3, we show there is a link surgery spectral sequence whose E 2-page is isomorphic to the reduced Khovanov homology of L and which converges to the symplectic instanton homology of Sigma( L).

The conservation physiology toolbox: status and opportunities

Abstract For over a century, physiological tools and techniques have been allowing researchers to characterize how organisms respond to changes in their natural environment and how they interact with human activities or infrastructure. Over time, many of these techniques have become part of the conservation physiology toolbox, which is used to monitor, predict, conserve, and restore plant and animal populations under threat. Here, we provide a summary of the tools that currently comprise the conservation physiology toolbox. By assessing patterns in articles that have been published in ‘Conservation Physiology’ over the past 5 years that focus on introducing, refining and validating tools, we provide an overview of where researchers are placing emphasis in terms of taxa and physiological sub-disciplines. Although there is certainly diversity across the toolbox, metrics of stress physiology (particularly glucocorticoids) and studies focusing on mammals have garnered the greatest attention, with both comprising the majority of publications (>45%). We also summarize the types of validations that are actively being completed, including those related to logistics (sample collection, storage and processing), interpretation of variation in physiological traits and relevance for conservation science. Finally, we provide recommendations for future tool refinement, with suggestions for: (i) improving our understanding of the applicability of glucocorticoid physiology; (ii) linking multiple physiological and non-physiological tools; (iii) establishing a framework for plant conservation physiology; (iv) assessing links between environmental disturbance, physiology and fitness; (v) appreciating opportunities for validations in under-represented taxa; and (vi) emphasizing tool validation as a core component of research programmes. Overall, we are confident that conservation physiology will continue to increase its applicability to more taxa, develop more non-invasive techniques, delineate where limitations exist, and identify the contexts necessary for interpretation in captivity and the wild.

Segmental osteotomies of the maxilla.

PubMed

Rosen, H M

1989-10-01

Multiple segment Le Fort I osteotomies provide the maxillofacial surgeon with the capabilities to treat complex dentofacial deformities existing in all three planes of space. Sagittal, vertical, and transverse maxillomandibular discrepancies as well as three-dimensional abnormalities within the maxillary arch can be corrected simultaneously. Accordingly, optimal aesthetic enhancement of the facial skeleton and a functional, healthy occlusion can be realized. What may be perceived as elaborate treatment plans are in reality conservative in terms of osseous stability and treatment time required. The close cooperation of an orthodontist well-versed in segmental orthodontics and orthognathic surgery is critical to the success of such surgery. With close attention to surgical detail, the complication rate inherent in such surgery can be minimized and the treatment goals achieved in a timely and predictable fashion.

Traumatic pancreaticoduodenal injury still remains challenging with high morbidity and mortality. Optimal management by performing simple and fast damage control surgery ensures better outcomes. A 36-year-old man was admitted with a combined pancreaticoduodenal injury after being assaulted. More than 80% of duodenal circumference (first portion) was disrupted and the neck of the pancreas was transected. Primary repair of the duodenum and pancreaticogastrostomy were performed. The stump of the proximal pancreatic duct was also sutured. The patient developed an intra-abdominal abscess with pancreatic fistula that eventually recovered by conservative treatment. Pancreaticogastrostomy can be a treatment option for pancreatic transection. Rapid and simple damage control surgery with functional preservation of the organ will be beneficial for trauma patients.

In the Luangwa Valley, Zambia, persistent poverty and hunger present linked challenges to rural development and biodiversity conservation. Both household coping strategies and larger-scale economic development efforts have caused severe natural resource degradation that limits future economic opportunities and endangers ecosystem services. A model based on a business infrastructure has been developed to promote and maintain sustainable agricultural and natural resource management practices, leading to direct and indirect conservation outcomes. The Community Markets for Conservation (COMACO) model operates primarily with communities surrounding national parks, strengthening conservation benefits produced by these protected areas. COMACO first identifies the least food-secure households and trains them in sustainable agricultural practices that minimize threats to natural resources while meeting household needs. In addition, COMACO identifies people responsible for severe natural resource depletion and trains them to generate alternative income sources. In an effort to maintain compliance with these practices, COMACO provides extension support and access to high-value markets that would otherwise be inaccessible to participants. Because the model is continually evolving via adaptive management, success or failure of the model as a whole is difficult to quantify at this early stage. We therefore test specific hypotheses and present data documenting the stabilization of previously declining wildlife populations; the meeting of thresholds of productivity that give COMACO access to stable, high-value markets and progress toward economic self-sufficiency; and the adoption of sustainable agricultural practices by participants and other community members. Together, these findings describe a unique, business-oriented model for poverty alleviation, food production, and biodiversity conservation. PMID:21873184

The maintenance and improvement of ecosystem services on the Tibet Plateau are critical for national ecological security in China and are core objectives of ecological conservation in this region. In this paper, ecosystem service benefits of the Tibet Ecological Conservation Project were comprehensively assessed by estimating and mapping the spatiotemporal variation patterns of critical ecosystem services on the Tibet Plateau from 2000 to 2015. Furthermore, we linked the benefit assessment to the sustainable spatial planning of future ecological conservation strategies. Comparing the 8 years before and after the project, the water retention and carbon sink services of the forest, grassland and wetland ecosystems were slightly increased after the project, and the ecosystem sand fixation service has been steadily enhanced. The increasing forage supply service of grassland significantly reduced the grassland carrying pressure and eased the conflict between grassland and livestock. However, enhanced rainfall erosivity occurred due to increased rainfall, and root-layer soils could not recover in a short period of time, both factors have led to a decline in soil conservation service. The warm and humid climate is beneficial for the restoration of ecosystems on the Tibet Plateau, and the implementation of the Tibet Ecological Conservation Project has had a positive effect on the local improvement of ecosystem services. A new spatial planning strategy for ecological conservation was introduced and aims to establish a comprehensive, nationwide system to protect important natural ecosystems and wildlife, and to promote the sustainable use of natural resources.

[Mood disorders and epilepsy surgery: A review].

PubMed

Yrondi, A; Arbus, C; Valton, L; Schmitt, L

2017-04-01

Historically, there is a strong link between depression and epilepsy. Patients with epilepsy are four to five times more likely to develop a depressive syndrome. It seems that the link between epilepsy and depression is bidirectional. There is little data on mood disorders secondary to epilepsy surgery. The goal of epilepsy surgery is to reduce the number and frequency of attacks, which in turn would allow improvements in mood disorders and cognitive impairment. A systematic search of the international literature was performed using the bibliographic search engines PubMed and Embase. The following MESH terms were used: epilepsy surgery AND (depression OR depressive disorder OR mood disorder). We also used the "related articles" of PubMed, bibliography surveys, conference abstracts and Google Scholar to identify additional relevant papers. Of the 130 studies found by the systematic search, 112 are excluded because they did not take into account the mood disorders secondary to epilepsy surgery. Fifteen studies are included in this review of the literature with a case study. Depression is the psychopathological condition that is the most frequently studied. According to several studies, the prevalence of depression is approximately 30% with nearly 70% of cases diagnosed during the first three months following epilepsy surgery. The majority of patients presented depressive symptoms during the first 3 to 12months after epilepsy surgery. In these studies, the risk of developing depression is correlated with the existence of previous depressive elements relative to the epilepsy surgery. A small number of studies reported cases of de novo depression. Studies have shown a correlation between very good to excellent control of epileptic seizures and a persistent improvement of mood disorders. It would seem that depressive symptoms post-surgery are more common when the surgical intervention concerns the temporal lobe and in particular mesial resections. There are only very few cases of maniac episodes. Hamid et al. showed an increased risk of suicide waning after the epilepsy surgery over a period of 5years. Mood disorders are common psychiatric comorbidities in epilepsy surgery. The detection, prevention, and treatment of these symptoms in patients eligible for epilepsy surgery pose major challenges for psychiatrists and neurologists, requiring their close collaboration.

Yeung, Trevor M; Sacchi, Matteo; Mortensen, Neil J; Spinelli, Antonino

2015-09-01

The Internet is a vast resource for patients to search for health information on the treatment of Crohn's disease. This study examines the quality of Web sites that provide information to adults regarding Crohn's disease, including treatment options and surgery. Two search engines (Google and Yahoo) and the search terms "surgery for Crohn's disease" were used. The first 50 sites of each search were assessed. Sites that fulfilled the inclusion criteria were evaluated for content and scored by using the DISCERN instrument, which evaluates the quality of health information on treatment choices. One hundred sites were examined, of which 13 were duplicates. Sixty-two sites provided patient-orientated information. The other sites included 7 scientific articles, 3 blogs, 2 links, 6 forums, 3 video links, and 4 dead links. Of the 62 Web sites that provided patient information for adults, only 15 (24.2%) had been updated within the past 2 years. Only 9 (14.5%) were affiliated with hospitals and clinics. The majority of sites (33, 53.2%) were associated with private companies with commercial interests. Only half of the Web sites provided details on treatment options, and most Web sites did not provide any information on symptoms and procedure details. Just 5 Web sites (8.1%) described the risks of surgery, and only 7 (11.3%) provided any information on the timescale for recovery. Overall, only 1 Web site (1.6%) was identified as being "good" or "excellent" with the use of the DISCERN criteria. Although the internet is constantly evolving, this study captures data at a specific time point. Search results may vary depending on geographical location. This study only assessed English language websites. The quality of patient information on surgery for Crohn's disease is highly variable and generally poor. There is potential for the Internet to provide valuable information, and clinicians should identify high-quality Web sites to guide their patients.

Effect of radiotherapy after breast-conserving surgery on 10-year recurrence and 15-year breast cancer death: meta-analysis of individual patient data for 10,801 women in 17 randomised trials.

After breast-conserving surgery, radiotherapy reduces recurrence and breast cancer death, but it may do so more for some groups of women than for others. We describe the absolute magnitude of these reductions according to various prognostic and other patient characteristics, and relate the absolute reduction in 15-year risk of breast cancer death to the absolute reduction in 10-year recurrence risk. We undertook a meta-analysis of individual patient data for 10,801 women in 17 randomised trials of radiotherapy versus no radiotherapy after breast-conserving surgery, 8337 of whom had pathologically confirmed node-negative (pN0) or node-positive (pN+) disease. Overall, radiotherapy reduced the 10-year risk of any (ie, locoregional or distant) first recurrence from 35·0% to 19·3% (absolute reduction 15·7%, 95% CI 13·7-17·7, 2p<0·00001) and reduced the 15-year risk of breast cancer death from 25·2% to 21·4% (absolute reduction 3·8%, 1·6-6·0, 2p=0·00005). In women with pN0 disease (n=7287), radiotherapy reduced these risks from 31·0% to 15·6% (absolute recurrence reduction 15·4%, 13·2-17·6, 2p<0·00001) and from 20·5% to 17·2% (absolute mortality reduction 3·3%, 0·8-5·8, 2p=0·005), respectively. In these women with pN0 disease, the absolute recurrence reduction varied according to age, grade, oestrogen-receptor status, tamoxifen use, and extent of surgery, and these characteristics were used to predict large (≥20%), intermediate (10-19%), or lower (<10%) absolute reductions in the 10-year recurrence risk. Absolute reductions in 15-year risk of breast cancer death in these three prediction categories were 7·8% (95% CI 3·1-12·5), 1·1% (-2·0 to 4·2), and 0·1% (-7·5 to 7·7) respectively (trend in absolute mortality reduction 2p=0·03). In the few women with pN+ disease (n=1050), radiotherapy reduced the 10-year recurrence risk from 63·7% to 42·5% (absolute reduction 21·2%, 95% CI 14·5-27·9, 2p<0·00001) and the 15-year risk of breast cancer death from 51·3% to 42·8% (absolute reduction 8·5%, 1·8-15·2, 2p=0·01). Overall, about one breast cancer death was avoided by year 15 for every four recurrences avoided by year 10, and the mortality reduction did not differ significantly from this overall relationship in any of the three prediction categories for pN0 disease or for pN+ disease. After breast-conserving surgery, radiotherapy to the conserved breast halves the rate at which the disease recurs and reduces the breast cancer death rate by about a sixth. These proportional benefits vary little between different groups of women. By contrast, the absolute benefits from radiotherapy vary substantially according to the characteristics of the patient and they can be predicted at the time when treatment decisions need to be made.

Definitive or conservative surgery for perforated gastric ulcer?--An unresolved problem.

PubMed

Sarath Chandra, Sistla; Kumar, S Siva

2009-04-01

Gastric ulcer perforation has not been the focus of many studies. In addition there is a need to analyze the results of gastric perforation separately and not along with duodenal perforations, to identify the factors influencing the outcome and to develop strategies for its management. Retrospective analysis of 54 patients presenting with gastric perforation. Mean age of the patients was 44.5 years with male preponderance. Morbidity following Closure of the perforation, acid reduction surgery and resection was not significantly different. Overall mortality was 16.6% with highest mortality 24.1% following simple closure. Mortality following simple closure and definitive surgery was not significantly different. Univariate analysis revealed preoperative shock, associated medical illness and surgical delay to be significant factors for mortality whereas on multivariate analysis, preoperative shock was the only independent predictor of mortality. Mortality increased with increasing Boey score but the association between the type of surgery and probability of survival was not statistically significant. Boey risk score is useful in predicting the outcome of surgical treatment for gastric perforation. Definitive surgery is not associated with greater morbidity or mortality compared to simple closure.

Oncoplastic Breast Surgery (OBS), which is a combination of oncological procedures and plastic surgery techniques, has recently gained widespread use. To assess the experiences, practice patterns and preferred approaches to Oncoplastic and Reconstructive Breast Surgery (ORBS) undertaken by general surgeons specializing in breast surgery in Turkey. Cross-sectional study. Between December 2013 and February 2014, an eleven-question survey was distributed among 208 general surgeons specializing in breast surgery. The questions focused on the attitudes of general surgeons toward performing oncoplastic breast surgery (OBS), the role of the general surgeon in OBS and their training for it as well as their approaches to evaluating cosmetic outcomes in Breast Conserving Surgery (BCS) and informing patients about ORBS preoperatively. Responses from all 208 surgeons indicated that 79.8% evaluated the cosmetic outcomes of BCS, while 94.2% informed their patients preoperatively about ORBS. 52.5% performed BCS (31.3% themselves, 21.1% together with a plastic surgeon). 53.8% emphasized that general surgeons should carry out OBS themselves. 36.1% of respondents suggested that OBS training should be included within mainstream surgical training, whereas 27.4% believed this training should be conducted by specialised centres. Although OBS procedure rates are low in Turkey, it is encouraging to see general surgeons practicing ORBS themselves. The survey demonstrates that our general surgeons aspire to learn and utilize OBS techniques.

Pre-surgery Disability Compensation Predicts Long-Term Disability among Workers with Carpal Tunnel Syndrome

2012-01-01

Background We sought to identify early risk factors for work disability compensation prior to and after carpal tunnel syndrome (CTS) surgery, and to determine whether pre-surgery disability compensation is associated with long-term disability. Methods Washington State workers’ compensation administrative data and data from interviews with workers 18 days (median) after submitting new workers’ compensation claims for CTS were examined. Baseline risk factors for pre-surgery disability compensation and for long-term disability (≥365 days of work disability compensation prior to two years after claim filing) were evaluated for workers who underwent CTS surgery and had at least one day of disability compensation (N=670). Results After adjustment for baseline long-term disability risk factors, workers with pre-surgery disability compensation had over five times the odds of long-term disability. Baseline factors in multiple domains, including job, psychosocial, clinical, and worker pain and function, were associated with both pre-surgery disability compensation and long-term disability. Conclusions Risk factors for work disability prior to and after CTS surgery are similar, and early work disability is a risk factor for long-term CTS-related disability. An integrated approach to CTS-related disability prevention could include identifying and addressing combined risk factors soon after claim filing, more efficient use of conservative treatments and appropriate work modifications to minimize early work loss, and, when indicated, timely surgical intervention.

The Hieracium and Pilosella (Lactuceae, Asteraceae) genera of closely related hawkweeds contain species with two different modes of gametophytic apomixis (asexual seed formation). Both genera contain polyploid species, and in wild populations, sexual and apomictic species co-exist. Apomixis is known to co-exist with sexuality in apomictic Pilosella individuals, however, apomictic Hieracium have been regarded as obligate apomicts. Here, a developmental analysis of apomixis within 16 Hieracium species revealed meiosis and megaspore tetrad formation in 1 to 7% of ovules, for the first time indicating residual sexuality in this genus. Molecular markers linked to the two independent, dominant loci LOSS OF APOMEIOSIS (LOA) and LOSS OF PARTHENOGENESIS (LOP) controlling apomixis in Pilosella piloselloides subsp. praealta were screened across 20 phenotyped Hieracium individuals from natural populations, and 65 phenotyped Pilosella individuals from natural and experimental cross populations, to examine their conservation, inheritance and association with reproductive modes. All of the tested LOA and LOP-linked markers were absent in the 20 Hieracium samples irrespective of their reproductive mode. Within Pilosella, LOA and LOP-linked markers were essentially absent within the sexual plants, although they were not conserved in all apomictic individuals. Both loci appeared to be inherited independently, and evidence for additional genetic factors influencing quantitative expression of LOA and LOP was obtained. Collectively, these data suggest independent evolution of apomixis in Hieracium and Pilosella and are discussed with respect to current knowledge of the evolution of apomixis. PMID:25026970

Obesity has been linked to an increased prevalence in multiple cancers. Studies have suggested a reduction in the overall risk of cancer after bariatric surgery. We reviewed the evidence for bariatric surgery reducing the risk of endometrial cancer. Data was extracted from PubMed, EMBASE, and Medline to perform a systematic review. Thirty-one full text articles were identified from 265 abstracts. Nine observational studies were relevant to endometrial cancer. In the five controlled studies, 462 of 113,032 (0.4%) patients receiving bariatric surgery versus 11,997 of 848,864 (1.4%) controls developed endometrial cancer, odds ratio of 0.317 (95% CI 0.161 to 0.627) using random effects model (P < 0.001). Bariatric surgery seems to reduce the risk of endometrial cancer; however, more research is required.

Attachment anxiety predicts IL-6 and length of hospital stay in coronary artery bypass graft surgery (CABG) patients.

The mechanisms underlying the association between adult attachment and health are not well understood. In the current study, we investigated the relationship between attachment anxiety, attachment avoidance, inflammation, and length of hospital stay in coronary artery bypass graft (CABG) surgery patients. 167 CABG patients completed an attachment questionnaire prior to surgery, and blood samples were taken before and after surgery to assess inflammatory activity. We found that attachment anxiety predicted higher plasma interleukin 6 (IL-6) concentration, and this association was mediated by self-reported sleep quality. Anxious attachment also predicted longer hospital stays following CABG surgery, even after controlling for demographic and clinical factors. These data suggest that increased levels of IL-6 may be a process linking adult attachment anxiety with health outcomes. Copyright © 2014. Published by Elsevier Inc.

Retrograde gastroesophageal intussusception after peroral endoscopic myotomy in a patient with achalasia cardia: A case report.

PubMed

Khan, Samiullah; Su, Shuai; Jiang, Kui; Wang, Bang-Mao

2018-01-01

Retrograde gastroesophageal intussusception (RGEI) is a relatively rare gastrointestinal (GI) disorder in which a portion of the stomach wall invaginates into the esophagus. More recently, peroral endoscopic myotomy (POEM) has emerged as an endoscopic alternative to surgical myotomy for achalasia, and, to the best of our knowledge, our case is the first RGEI after POEM to be reported. A 22-year-old male was presented with a history of vomiting, intractable retching and hematemesis for 3 days. He had a history of achalasia and underwent POEM 3 years ago caused by symptoms of severe dysphagia to solid and liquid. Initially, the patient was diagnosed with a blood-filled esophagus, and the mid esophagus was occluded with a ball-like mass, however, the final diagnosis of RGEI was made by thoracotomy. A therapeutic strategy of conservative treatment and left transthoracic surgery were applied. The surgery and post operative course were uneventful, and he remained asymptomatic 1 year after operation. POEM is a reliable and minimally invasive endoscopic method for esophageal achalasia. Early recognition and severity of RGEI are essential to decrease the unwanted complications. Upper GI series, esophagogastroduodenoscopy and computed tomography scan are helpful for diagnostic purposes of RGEI. Conservative treatment, endoscopic intervention, and surgery are the mainstay of treatments for RGEI. Copyright © 2017 The Authors. Published by Wolters Kluwer Health, Inc. All rights reserved.

2015-12-01

This laboratory-based investigation compares the topographic outcomes of conventional penetrating keratoplasty with that of a novel procedure in which donor corneas are cross-linked prior to keratoplasty. Penetrating keratoplasty procedures with continuous running sutures were carried out in a porcine whole globe model. Sixty eyes were randomly paired as 'donor' and 'host' tissue before being assigned to one of two groups. In the cross-linked group, donor corneas underwent riboflavin/UVA cross-linking prior to being trephined and sutured to untreated hosts. In the conventional keratoplasty group, both host and donor corneas remained untreated prior to keratoplasty. Topographic and corneal wavefront measurements were performed following surgery, and technical aspects of the procedure evaluated. Mean keratometric astigmatism was significantly lower in the cross-linked donor group at 3.67D (SD 1.8 D), vs. 8.43 D (SD 2.4 D) in the conventional keratoplasty group (p < 0.005). Mean wavefront astigmatism was also significantly reduced in the cross-linked donor group 4.71 D (SD 2.1) vs. 8.29D (SD 3.6) in the conventional keratoplasty group (p < 0.005). Mean RMS higher order aberration was significantly lower in the cross-linked donor group at 1.79 um (SD 0.98), vs. 3.05 um (SD 1.9) in the conventional keratoplasty group (P = 0.02). Qualitative analysis revealed less tissue distortion at the graft-host junction in the cross-linked group. Cross-linking of donor corneas prior to keratoplasty reduces intraoperative induced astigmatism and aberrations in an animal model. Further studies are indicated to evaluate the implications of this potential modification of keratoplasty surgery.

Instead of performing conventional surgery, an alternative conservative treatment was planned in the form of cryotherapy with the help of closed nitrous oxide probe. Seeing the satisfactory results obtained, cryotherapy can be suggested as an atraumatic, bloodless and effective chair side procedure for treating vascular gingival enlargement. PMID:28580218

Respiratory complications due to mechanical obstruction of the airways can occur following pediatric cardiac surgery. Clinically significant intrathoracic vascular compression of the airway can occur when extensive dissection and mobilization of arch and neck vessels is involved as in repair of interrupted aortic arch. This case report describes a neonate who underwent interrupted aortic arch repair along with an arterial switch operation and developed a left lung collapse immediately after tracheal extubation. Fiber-optic bronchoscopy revealed vascular compression as the real culprit. The child was successfully managed conservatively.

Medical and surgical treatment of haemorrhoids and anal fissure in Crohn’s disease: a critical appraisal

2013-01-01

Background The principle to avoid surgery for haemorrhoids and/or anal fissure in Crohn’s disease (CD) patients is still currently valid despite advances in medical and surgical treatments. In this study we report our prospectively recorded data on medical and surgical treatment of haemorrhoids and anal fissures in CD patients over a period of 8 years. Methods Clinical data of patients affected by perianal disease were routinely and prospectively inserted in a database between October 2003 and October 2011 at the Department of Surgery, Tor Vergata University Hospital, Rome. We reviewed and divided in two groups records on CD patients treated either medically or surgically according to the diagnosis of haemorrhoids or anal fissures. Moreover, we compared in each group the outcome in patients with prior diagnosis of CD and in patients diagnosed with CD only after perianal main treatment. Results Eighty-six CD patients were included in the study; 45 were treated for haemorrhoids and 41 presented with anal fissure. Conservative approach was initially adopted for all patients; in case of medical treatment failure, the presence of stable intestinal disease made them eligible for surgery. Fifteen patients underwent haemorrhoidectomy (open 11; closed 3; stapled 1), and two rubber band ligation. Fourteen patients required surgery for anal fissure (Botox ± fissurectomy 8; LIS 6). In both groups we observed high complication rate, 41.2% for haemorrhoids and 57.1% for anal fissure. Patients who underwent haemorrhoidectomy without certain diagnosis of CD had significantly higher risk of complications. Conclusions Conservative treatment of proctologic diseases in CD patients has been advocated given the high risk of complications and the evidence that spontaneous healing may also occur. From these preliminary results a role of surgery is conceivable in high selected patients, but definitve conclusions can’t be made. Further randomized trials are needed to establish the efficacy of the surgical approach, giving therapeutic recommendations and guidelines. PMID:23496835

BACKGROUND Little is known about the relation between surgical care for breast cancer at for-profit hospitals and subsequent use of adjuvant radiation therapy (RT). Among Medicare beneficiaries, we examined whether hospital ownership status is associated with the use of breast brachytherapy – a newer and more expensive modality – as well as overall RT. METHODS We conducted a retrospective study of female Medicare beneficiaries receiving breast-conserving surgery for invasive breast cancer in 2008 and 2009. We assessed the relationship between hospital ownership and receipt of brachytherapy or overall RT using hierarchical generalized linear models. RESULTS The sample consisted of 35,118 women, 8.0% of whom had surgery at for-profit hospitals. Among patients who received RT, those who underwent surgery at for-profit hospitals were significantly more likely to receive brachytherapy (20.2%) than patients treated at not-for-profit hospitals (15.2%; OR for for-profit vs. not-for-profit: 1.50; 95%CI: 1.23–1.84; p<0.001). Among women aged 66–79, there was no relation between hospital ownership status and overall RT use. Among women aged 80–94 years old – the group least likely to benefit from RT due to shorter life expectancy – receipt of surgery at a for-profit hospital was significantly associated with higher overall RT use (OR: 1.22; 95%CI: 1.03–1.45, p=0.03) and brachytherapy use (OR: 1.66; 95%CI: 1.18–2.34, p=0.003). CONCLUSIONS Surgical care at for-profit hospitals was associated with increased use of the newer and more expensive RT modality, brachytherapy. Among the oldest women, who are least likely to benefit from RT, surgical care at a for-profit hospital was associated with higher overall RT use, with this difference largely driven by the use of brachytherapy.

Small-bowel obstruction is a frequent disorder in emergency medicine and represents a major burden for patients and health care systems worldwide. Within the past years, progress has been made regarding the management of small-bowel obstructions, including the use of contrast agent swallow as a tool in the decision-making process. This is a prospective controlled study investigating the central role of contrast agent swallow in the diagnostic and treatment algorithm for small-bowel obstruction at a university department of surgery. Endpoints were the correct identification of patients who needed operative treatment and the accuracy of a conservative treatment decision including the analysis of dropout from this routine algorithm. We performed a single-center analysis of 181 consecutive patients diagnosed with a small-bowel obstruction based on clinical, radiologic, and sonographic findings. Patients with clinical signs of strangulation or peritonitis underwent immediate surgery (group 1). Patients without signs of peritonitis and incomplete stop in the initial abdominal plain film were considered eligible for Gastrografin® challenge (group 2). Seventy-six of the 181 patients (42.0%) underwent immediate surgery. A Gastrografin® challenge was initialized in 105 of the 181 patients (58.0%). Twenty of these 105 patients (19.1%) with persisting or progressive symptoms and absence of contrast agent in the colon after 12 and 24 h subsequently underwent surgery. Here, a segmental bowel resection was necessary in 6 of these 20 patients (30.0%). In 16 out of 20 patients (80.0%) who failed the Gastrografin® challenge, a corresponding correlate in terms of a strangulation was detected intraoperatively. The Gastrografin® challenge had a specificity of 96% and a sensitivity of 100%; accuracy to predict the need for exploration was 96%. A straightforward algorithm based mainly on contrast agent swallow for patients with small-bowel obstructions enabled a timely and very accurate differentiation between patients qualifying for conservative and operative treatment.

Portal hypertension is a common and potentially devastating condition in children. Notwithstanding advances in the nonsurgical management of portal hypertension, surgery remains an important treatment modality in select patients. We report here on our experience in the past 12 years. To describe the profile of, indication for, and complications of shunt surgery in children with portal hypertension. Twelve children underwent shunt surgery between 2005 and 2017. Patient records were reviewed. Fourteen procedures were performed on 12 patients during the study period. The median age at surgery was 6.5 (range 1 - 18) years. Six patients were male. Gastrointestinal bleeding that was not amenable to endoscopic control was the most common indication for surgery. Portal vein thrombosis was the most common cause of portal hypertension in our series (n=11). Two-thirds (8/12) of all patients had an identifiable underlying risk factor for portal vein thrombosis. One-third of all patients (4/12) underwent a meso-portal bypass procedure (Rex shunt), while 58% (7/12) were managed with a distal splenorenal shunt. All patients received postoperative thromboprophylaxis. We experienced a single mortality, 1 patient experienced shunt thrombosis that required revision shunt surgery, and 2 patients experienced anastomotic strictures, with one being managed with revision surgery and the other currently awaiting radiological venoplasty. Surgery is a safe and important tool in the management of children with non-cirrhotic portal hypertension and those with sufficient hepatic reserve who fail to respond to more conservative methods for the treatment of side effects of portal hypertension.

The objective was to determine the results of the treatment of severe and/or refractory epistaxis requiring hospital admission. In addition, the results of arterial ligation versus embolization were compared. Sixty-three patients with severe and/or refractory epistaxis requiring hospital admission between August 2014 and December 2016 were included prospectively. Eleven patients (17%) underwent embolization, 5 (8%) endoscopy ligation and the remaining 47 (75%) underwent conservative treatment with tamponade. The mean age of the patients in which conservative measures were sufficient was 72 years, while the age of those treated with embolization was 71 years and of those who underwent surgery was 53 years. For the patients who underwent conservative treatment or surgery, the average stay was 6 days, compared to 9 days for those who underwent embolization. One patient suffered a hemispheric stroke after embolization. No post-surgical complications were observed. Most cases of severe and/or refractory epistaxis are resolved by conventional tamponade. Endoscopy ligation is associated with a decrease in hospital stay, without serious complications. It is advisable to have all the possible therapeutic options available, for which the presence of interventional radiologists and experienced surgeons is essential to avoid complications and decide the treatment to be performed individually for each patient.

The Mayo metaphysical conservative femoral stem (Zimmer, Warsaw, Indiana) is a wedge-shaped implant designed to transfer loads proximally, reduce femoral destruction, and enable the preservation of bone stock in the proximal femur. Thus, it is a potentially preferred prosthesis for active, non-elderly patients who may require additional future surgeries. This retrospective case study analyzed the outcomes of consecutive patients who underwent total hip replacements with this stem between May 2001 and February 2013. All patients underwent clinical assessment, radiological evaluation for the presence and development of radiolucent lines, and functional assessment (numerical analog scale, Harris hip score, and Short Form-12 questionnaire). Ninety-five hips (79 patients) were available for analysis. The patients' mean age was 43 years (range, 18-64 years), and the mean follow-up was 97 months (range, 26.9-166 months). The postoperative clinical assessments and functional assessments revealed significant improvements. Sixteen patients (20.3%) had 18 orthopedic complications, the most common of which were an intraoperative femoral fracture and implant dislocation requiring revision surgeries in 10 hips (10.5%). Radiological analysis revealed evidence of femoral remodeling in 64 (67.4%) implants, spot welds (neocortex) in 35 (36.8%), and osteolysis in 3 (3.2%). These results suggest that the conservative hip femoral implant has an unacceptable complication rate for non-elderly patients. [Orthopedics. 201x; xx(x):xx-xx.]. Copyright 2018, SLACK Incorporated.

Mitomycin C in pterygium treatment

PubMed Central

Martins, Thiago Gonçalves dos Santos; Costa, Ana Luiza Fontes de Azevedo; Alves, Milton Ruiz; Chammas, Roger; Schor, Paulo

2016-01-01

Pterygium is a benign lesion usually growing from the nasal side of the conjunctiva onto the cornea. Most cases of pterygium does not cause problem or requires specific treatment. The exact cause of pterygium is not clear yet, but some factors are pointed as causes, being the most important the long-term ultraviolet ray exposure. Pterygium surgery is usually considered when there are symptoms that do not respond to conservative treatment. Recurrence is the main complication of the surgery, and much has been done to avoid it. Mitomycin C (MMC) has been used as a fibroblast proliferation inhibitor during the surgery to reduce the chance of recurrence of the pterygium. This review describes the use of MMC as an adjunctive, the optimal dosage, the duration of administration of MMC and possible complications, when used during, after and before the surgery. Most studies suggest that increased exposure (dose or duration) of MMC is associated with a lower recurrence, but with higher risks of complications. PMID:27158622

Chronic pancreatitis is a progressive inflammatory disease giving rise to several complications that need to be treated accordingly. Because pancreatic surgery has significant morbidity and mortality, less invasive therapy seems to be an attractive option. This paper reviews current state-of-the-art strategies to treat chronic pancreatitis without surgery and the current guidelines for the medical therapy of chronic pancreatitis. Endoscopic therapy of complications of chronic pancreatitis such as pain, main pancreatic duct strictures and stones as well as pseudocysts is technically feasible and safe. The long-term outcome, however, is inferior to definitive surgical procedures such as resection or drainage. On the other hand, the medical therapy of pancreatic endocrine and exocrine insufficiency is well established and evidence based. Endoscopic therapy may be an option to bridge for surgery and in children/young adolescents and those unfit for surgery. Pain in chronic pancreatitis as well as treatment of pancreatic exocrine insufficiency follows established guidelines. Copyright © 2013 S. Karger AG, Basel.

To analyze the spectrum of testicular tumors in prepubertal children and the therapeutic resultants in an unselected population. Our hospital database was analyzed for testicular tumors from January 1995 to December 2010 concerning clinical presentation, treatment and therapeutic results. Eight patients were operated on because of testicular tumors. In six cases (75%) the tumor was benign: benign teratoma (four cases), epidermoid cyst (one case) and immature teratoma (one case). Two patients (25%) had a malignant tumour: yolk-sac tumour (two cases). All this children underwent surgery. Radical inguinal orchidectomy was performed in six cases and conservative surgery was performed in two cases. One patient has received adjuvant chemotherapy. Follow-up was uneventfully three years after primary surgery. In prepubertal children, most testicular tumours are benign. If tumour markers were negative testis-preserving surgery can be proposed, complete excision of the tumour should be ascertained. In the case of testicular teratoma, the possibility of contralateral tumour should be considered in the follow-up.

Chylous pericardial effusion is a rarely reported complication of lung cancer surgery. Here, we report a case of an elderly man who suffered chylous pericardial effusion after radical right upper lung resection for cancer. The massive chylous effusion first occurred in the pericardium, drained to the right chest after the drainage of the hydropericardium and subsequently moved back to the pericardium again. Lymphoscintigraphy examination indicated that a chylous fistula was present in the plane of the tracheal carina. After failure to control the chylous effusion with conservative medical treatment, the patient underwent video-assisted thoracic surgery through the left chest for thoracic duct ligation and pericardial fenestration. The patient was ultimately discharged without recurrence of the effusion after surgical treatment. This case report discusses the possible mechanism of chylopericardium after lung cancer surgery and suggests some strategies to prevent postoperative chylous pericardial effusion. © The Author 2017.

Are Rab Proteins the Link Between Golgi Organization and Membrane Trafficking?

PubMed Central

Liu, Shijie; Storrie, Brian

2014-01-01

The fundamental separation of Golgi function between subcompartments termed cisternae is conserved across all eukaryotes. Likewise, Rab proteins, small GTPases of the Ras superfamily, are putative common coordinators of Golgi organization and protein transport. However, despite sequence conservation, e.g., Rab6 and Ypt6 are conserved proteins between humans and yeast, the fundamental organization of the organelle can vary profoundly. In the yeast Sacchromyces cerevisiae, the Golgi cisternae are physically separated from one another while, in mammalian cells, the cisternae are stacked one upon the other. Moreover, in mammalian cells many Golgi stacks are typically linked together to generate a ribbon structure. Do evolutionarily conserved Rab proteins regulate secretory membrane trafficking and diverse Golgi organization in a common manner? In mammalian cells, some Golgi associated Rab proteins function in coordination of protein transport and maintenance of Golgi organization. These include Rab6, Rab33B, Rab1, Rab2, Rab18 and Rab43. In yeast, these include Ypt1, Ypt32 and Ypt6. Here, based on evidence from both yeast and mammalian cells, we speculate on the essential role of Rab proteins in Golgi organization and protein transport. PMID:22581368

Objective To characterise incidence and healthcare costs associated with persistent postoperative pain (PPP) following lumbar surgery. Design Retrospective, population-based cohort study. Setting Clinical Practice Research Datalink (CPRD) and Hospital Episode Statistics (HES) databases. Participants Population-based cohort of 10 216 adults who underwent lumbar surgery in England from 1997/1998 through 2011/2012 and had at least 1 year of presurgery data and 2 years of postoperative follow-up data in the linked CPRD–HES. Primary and secondary outcomes measures Incidence and total healthcare costs over 2, 5 and 10 years attributable to persistent PPP following initial lumbar surgery. Results The rate of individuals undergoing lumbar surgery in the CPRD–HES linked data doubled over the 15-year study period, fiscal years 1997/1998 to 2011/2012, from 2.5 to 4.9 per 10 000 adults. Over the most recent 5-year period (2007/2008 to 2011/2012), on average 20.8% (95% CI 19.7% to 21.9%) of lumbar surgery patients met criteria for PPP. Rates of healthcare usage were significantly higher for patients with PPP across all types of care. Over 2 years following initial spine surgery, the mean cost difference between patients with and without PPP was £5383 (95% CI £4872 to £5916). Over 5 and 10 years following initial spine surgery, the mean cost difference between patients with and without PPP increased to £10 195 (95% CI £8726 to £11 669) and £14 318 (95% CI £8386 to £19 771), respectively. Extrapolated to the UK population, we estimate that nearly 5000 adults experience PPP after spine surgery annually, with each new cohort costing the UK National Health Service in excess of £70 million over the first 10 years alone. Conclusions Persistent pain affects more than one-in-five lumbar surgery patients and accounts for substantial long-term healthcare costs. There is a need for formal, evidence-based guidelines for a coherent, coordinated management strategy for patients with continuing pain after lumbar surgery. PMID:28893756

Kaptanoglu, Levent; Kurt, Necmi; Sikar, Hasan Ediz

2017-03-01

Liver injuries remain major obstacle for successful treatment, due to size and location of the liver. Requirement for surgery should be determined by clinical factors, most notably hemodynamical state. In this present study we tried to declare our approach to liver traumas. We also tried to emphasize the importance of conservative treatment, since surgeries for liver traumas carry high mortality rates. Patients admitted to the Department of Emergency Surgery at Kartal Research and Education Hospital, due to liver trauma were retrospectively analyzed between 2003 and 2013. Patient demographics, hepatic panel, APTT (activated partial thromboplastin time), PT (prothrombin time), INR (international normalized ratio), fibrinogen, biochemistry panel were recorded. Hemodynamic instability was the most prominent factor for surgery decision, in the lead of current Advanced Trauma Life Support (ATLS) protocols. Operation records and imaging modalities revealed liver injuries according to the Organ Injury Scale of the American Association for the Surgery of Trauma. 300 patients admitted to emergency department were included in our study (187 males and 113 females). Mean age was 47 years (range, 12-87). The overall mortality rate was 13% (40 out of 300). Major factor responsible for mortality rates and outcome was stability of cases on admission. 188 (% 63) patients were counted as stable, whereas 112 (% 37) cases were found unstable (blood pressure ≤ 90, after massive resuscitation). 192 patients were observed conservatively, whereas 108 cases received abdominal surgery. High levels of AST, ALT, LDH, INR, creatinine and low levels of fibrinogen and low platelet counts on admission were found to be associated with mortality and these cases also had Grade 4 and 5 injuries. Hemodynamic instability on admission and the type and grade of injury played major role in mortality rates). Packing was performed in 35 patients, with Grade 4 and 5 injuries. Mortality rate was %13 (40 out of 300). A multidisciplinary approach to the management of hepatic injuries has evolved over the last few decades, but the basic principles of trauma continue to be observed. Diagnostic and therapeutic endeavors are chosen based mainly on the stability of the patient. Stable patients with reliable examinations and available resources can be managed nonoperatively. Unstable patients require surgery. Our current approach to liver traumas is non operative technique, if possible. Copyright © 2017 IJS Publishing Group Ltd. Published by Elsevier Ltd.

On January 1, 2008, the Society of Thoracic Surgeons Adult Cardiac Surgery Database began collecting Social Security numbers in its new version 2.61. This study includes all Society of Thoracic Surgeons Adult Cardiac Surgery Database records for operations with nonmissing Social Security numbers between January 1, 2008, and December 31, 2010, inclusive. To match records between the Society of Thoracic Surgeons Adult Cardiac Surgery Database and the Social Security Death Master File, we used a combined probabilistic and deterministic matching rule with reported high sensitivity and nearly perfect specificity. Between January 1, 2008, and December 31, 2010, the Society of Thoracic Surgeons Adult Cardiac Surgery Database collected data for 870,406 operations. Social Security numbers were available for 541,953 operations and unavailable for 328,453 operations. According to the Society of Thoracic Surgeons Adult Cardiac Surgery Database, the 30-day mortality rate was 17,757/541,953 = 3.3%. Linkage to the Social Security Death Master File identified 16,565 cases of suspected 30-day deaths (3.1%). Of these, 14,983 were recorded as 30-day deaths in the Society of Thoracic Surgeons database (relative sensitivity = 90.4%). Relative sensitivity was 98.8% (12,863/13,014) for suspected 30-day deaths occurring before discharge and 59.7% (2120/3551) for suspected 30-day deaths occurring after discharge. Linkage to the Social Security Death Master File confirms the accuracy of data describing "mortality within 30 days of surgery" in the Society of Thoracic Surgeons Adult Cardiac Surgery Database. The Society of Thoracic Surgeons and Social Security Death Master File link reveals that capture of 30-day deaths occurring before discharge is highly accurate, and that these in-hospital deaths represent the majority (79% [13,014/16,565]) of all 30-day deaths. Capture of the remaining 30-day deaths occurring after discharge is less complete and needs improvement. Efforts continue to encourage Society of Thoracic Surgeons Database participants to submit Social Security numbers to the Database, thereby enhancing accurate determination of 30-day life status. The Society of Thoracic Surgeons and Social Security Death Master File linkage can facilitate ongoing refinement of mortality reporting.

Abstract Background and Purpose Sciatica is a common clinical condition that can be extremely painful, disabling and life‐changing. Whether conservative or surgical treatment for sciatica secondary to an intervertebral disc prolapse is most effective is still much debated. An important component of conservative treatment is physiotherapy, which aims to promote physical and psychological health for the patient, whilst resorption of the disc takes place. This paper reports a qualitative study of patients' views and experiences of a bespoke physiotherapy intervention for the treatment of sciatica. Methods A qualitative study nested within a pilot randomized controlled trial of bespoke physiotherapy for the treatment of patients with sciatica awaiting lumbar microdiscectomy surgery. Patients randomized to receive bespoke physiotherapy in the intervention arm of the trial were invited to take part in semi‐structured interviews. Twenty‐one in‐depth, semi‐structured interviews took place. All interviews were recorded, fully transcribed and thematically analysed. Results Most patients in the sample found the physiotherapy valuable, appreciating the individual nature of the approach, the exercises to reduce pain and discomfort, techniques for improving functional spinal movement, walking and dynamic posture, and manual therapy and cardiovascular exercise. A small number did not find the physiotherapy of benefit. Sixteen patients in the sample went on to proceed with surgery, but most of these found value in having had the physiotherapy first. Discussion Many patients with sciatica appreciate the value of physiotherapy prior to surgery. Future research should examine patients' experiences of bespoke physiotherapy delivered within primary care.

Rectus sheath hematoma (RSH) is an uncommon cause of acute abdominal pain. It may mimic a wide variety of intraabdominal disorders thus frequently leading to delay in treatment, increased morbidity or even in an unnecessary surgery. This is a retrospective study of 10 patients with RSH who were treated in our department over a five-year period. There were 6 (60%) men and 4 (40%) women ranging in age from 38 to 86 years, with a mean age of 57.1 years. The most common clinical presentation was a palpable abdominal mass associated with abdominal pain. Computed tomography (CT) established the diagnosis in 100% of the cases. 4 patients had type I hematoma, 3 had type II hematoma and 3 had type III hematoma. Anticoagulation therapy was the most common predisposing factor. Conservative treatment was effective in 90% of the cases and in all cases of spontaneous RSHs in patients under anticoagulation therapy. One patient, who developed a very severe RSH following an abdominal injection of low-molecular-weight heparin (LMWH), underwent surgery. All patients with type III hematoma required blood transfusion. RSH should be considered in the differential diagnosis of the elderly patients under anticoagulation therapy presenting with acute abdominal pain and a palpable mass. CT is the diagnostic modality of choice. Conservative treatment is feasible in most cases. Early diagnosis is mandatory in order to avoid morbidity or unnecessary surgery. In order to prevent a traumatic RSH, trocar insertion under direct vision during laparoscopic surgery and careful attention in the abdominal administration of LMWH are essential.

Intracranial dural arteriovenous fistulas (DAVFs) of the transverse and sigmoid sinuses (TSS) are rare in Asian populations. This study sought to evaluate the treatment outcomes of intracranial TSS DAVFs at a single Asian institute. Between 1989 and 2007, 122 patients presented to the Seoul National University Hospital with intracranial DAVFs; we performed a retrospective analysis of the 38 patients (31.1%) with TSS DAVFs. The common clinical presentations were headache (44.7%), tinnitus (39.5%), and intracranial hemorrhage (26.3%), and 71.1% had Borden type II or III lesions. Two patients were conservatively managed, two underwent surgery, and 34 were treated endovascularly with transarterial embolization (TAE), transvenous embolization (TVE), or both. The complete occlusion rate immediately after treatment was 50%. Of the 31 patients (81.6%) who underwent follow-up angiography, initial complete occlusion was achieved in 51.6%, and, at the last follow-up, the complete occlusion rate was 64.5%, with the surgery and TVE groups achieving 100% occlusion. The clinical cure rate was 34.2%, and 86.8% of patients had a favorable clinical outcome. However, all patients in both the surgery and TVE groups achieved a favorable clinical outcome. Four (26.7%) of 15 lesions with initially partial embolization showed delayed occlusion. Five patients (13.2%) exhibited clinical or angiographic signs of recurrence, and five patients had permanent complications. TSS DAVFs were less common than cavernous sinus DAVFs, unlike in Western countries, but the angiographic and clinical characteristics of TSS DAVFs were similar to those in Western countries. TSS DAVFs were successfully managed with different modalities, but both surgery and TVE were superior to conservative management or TAE. Copyright © 2012 Elsevier Ltd. All rights reserved.

CT contrast extravasation in the upper extremity: strategies for management.

2010-01-01

Extravasation of CT scan contrast media into upper extremity subcutaneous tissue is a relatively frequent complication of injection. Potential sequelae of extravasation include compartment syndrome, skin sloughing, and necrosis. Many institutions institute protocols requiring inpatient plastic surgery consultations immediately following extravasation injury to the upper extremity. We hypothesize that conversion to non-ionic contrast media for contrast CT studies has greatly reduced the incidence of severe extravasation injuries, and may alleviate the need for routine hand surgery consultations. Records from 102 consecutive CT contrast media extravasation injuries were identified. Data acquired from a single institution included type and amount of contrast extravasated, anatomic location, post-procedural clinical symptoms, whether consult was obtained, and final recommendations and outcome. In 102 consecutive cases, immediate surgical therapy was necessary in 0. Non-ionic medium was used in 94% of these cases, and ionic dye was used in 6%. Extravasation of less than 100 cc occurred in 90%, and only 10% were greater. Plastic surgery consultation was immediately obtained in 42% of cases. Factors prompting consultation included extravasation >30 cc, and the presence of erythema or induration. Trends for consultation remained without discernable pattern when patients were stratified by age, amount of extravasate, or anatomic location. Conservative management was recommended in all cases. This included elevation of the extremity, frequent pulse and sensation exams, local message, and temporary splinting. There were no secondary complications requiring surgical intervention. Extravasation of non-ionic CT contrast media appears to be innocuous and can be treated with conservative therapy. Plastic surgery consultation should be obtained when there are obvious signs of skin and soft tissue compromise or symptoms of compartment syndrome. Copyright 2010 Surgical Associates Ltd.

Treatment of patients with lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) may affect the quality of sexual function and ejaculation. The effect of new surgical procedures, which are currently available to treat BPH, on erection and ejaculation, has been poorly studied. This study aimed to assess the effect of thulium laser enucleation of the prostate (ThuLEP) on sexual function and retrograde ejaculation in patients with LUTS secondary to BPH. We performed a prospective study in 110 consecutive patients who had undergone ThuLEP to analyze changes in sexual function and urinary symptoms. To evaluate changes in erection and ejaculation, and the effect of urinary symptoms on the quality of life (QoL), five validated questionnaires were used: the ICIQ-MLUTSsex, MSHQ-EjD, International Index of Erectile Function 5, International Prognostic Scoring System (IPSS) questionnaire, and QoL index of the intraclass correlation coefficients. Patients also underwent IPSS and flowmetry to assess the outcome of flow. Patients were evaluated before surgery and 3-6 months after ThuLEP, whereas those with previous abdominal surgery were excluded. The patients' mean age was 67.83 years. Postoperative urinary symptoms improved after surgery. No significant differences in erectile function before and after surgery were observed. As compared with other techniques described in the literature, the percentage of patients with conserved ejaculation increased by 52.7% after ThuLEP. ThuLEP positively affects urinary symptoms and their effect on the QoL of patients as assessed by questionnaire scores. While endoscopic management of BPH (e.g. transurethral resection of the prostate) causes retrograde ejaculation in most patients, those who undergo ThuLEP have conserved ejaculation and erectile function.

To evaluate the effect of nurse case management on the treatment of older women with breast cancer. Randomized prospective trial. Sixty surgeons practicing at 13 community and two public hospitals in southeast Texas. Three hundred thirty-five women (166 control and 169 intervention) aged 65 and older newly diagnosed with breast cancer. Women seeing surgeons randomized to the intervention group received the services of a nurse case manager for 12 months after the diagnosis of breast cancer. The primary outcome was the type and use of cancer-specific therapies received in the first 6 months after diagnosis. Secondary outcomes were patient satisfaction and arm function on the affected side 2 months after diagnosis. More women in the intervention group received breast-conserving surgery (28.6% vs 18.7%; P=.031) and radiation therapy (36.0% vs 19.0%; P=.003). Of women undergoing breast-conserving surgery, greater percentages in the case management group received adjuvant radiation (78.3% vs 44.8%; P=.001) and axillary dissection (71.4% vs 44.8%; P=.057). Women in the case management group were also more likely to receive more breast reconstruction surgery (9.3% vs 2.6%, P=.054), and women in the case management group with advanced cancer were more likely to receive chemotherapy (72.7% vs 30.0%, P=.057). Two months after surgery, higher percentages of women in the case manager group had normal arm function (93% vs 84%; P=.037) and were more likely to state that they had a real choice in their treatment (82.2% vs 69.9%, P=.020). Women with indicators of poor social support were more likely to benefit from nurse case management. Nurse case management results in more appropriate management of older women with breast cancer.

Previous studies have shown that children with isolated linear skull fractures have excellent clinical outcomes and low risk of surgery. We wish to identify other injury patterns within the spectrum of paediatric mild head injury, which need only conservative management. Children with low risk of evolving neurosurgical lesions could be safely managed in primary hospitals. We retrospectively analysed all children with mild head injury (i.e. admission Glasgow coma score 13-15) and skull fracture or haematoma on a head computed tomography scan admitted to Westmead Children's Hospital, Sydney over the years 2009-2014. Data were collected regarding demographics, clinical findings, mechanism of injury, head computed tomography scan findings, neurosurgical intervention, outcome and length of admission. Wilcoxon paired test was used with P value <0.05 considered significant. Four hundred and ten children were analysed. Three hundred and eighty-one (93%) children were managed conservatively, 18 (4%) underwent evacuation of extradural haematoma (TBI surgery) and 11 (3%) needed fracture repair surgery. Two children evolved a surgical lesion 24 h post-admission. Only 17 of 214 children transferred from peripheral hospitals needed neurosurgery. Overall outcomes: zero deaths, one needed brain injury rehabilitation and 63 needed child protection unit intervention. Seventy-five percentage of children with non-surgical lesions were discharged within 2 days. Eighty-three percentage of road transfers were discharged within 3 days. Children with small intracranial haematomas and/or skull fractures who need no surgery only require brief inpatient symptomatic treatment and could be safely managed in primary hospitals. Improved tertiary hospital transfer guidelines with protocols to manage clinical deterioration could have cost benefit without risking patient safety. © 2017 Royal Australasian College of Surgeons.

To determine the impact of surgical site infections (SSIs) on health care costs following common ambulatory surgical procedures throughout the cost distribution. Data on costs of SSIs following ambulatory surgery are sparse, particularly variation beyond just mean costs. We performed a retrospective cohort study of persons undergoing cholecystectomy, breast-conserving surgery, anterior cruciate ligament reconstruction, and hernia repair from December 31, 2004 to December 31, 2010 using commercial insurer claims data. SSIs within 90 days post-procedure were identified; infections during a hospitalization or requiring surgery were considered serious. We used quantile regression, controlling for patient, operative, and postoperative factors to examine the impact of SSIs on 180-day health care costs throughout the cost distribution. The incidence of serious and nonserious SSIs was 0.8% and 0.2%, respectively, after 21,062 anterior cruciate ligament reconstruction, 0.5% and 0.3% after 57,750 cholecystectomy, 0.6% and 0.5% after 60,681 hernia, and 0.8% and 0.8% after 42,489 breast-conserving surgery procedures. Serious SSIs were associated with significantly higher costs than nonserious SSIs for all 4 procedures throughout the cost distribution. The attributable cost of serious SSIs increased for both cholecystectomy and hernia repair as the quantile of total costs increased ($38,410 for cholecystectomy with serious SSI vs no SSI at the 70th percentile of costs, up to $89,371 at the 90th percentile). SSIs, particularly serious infections resulting in hospitalization or surgical treatment, were associated with significantly increased health care costs after 4 common surgical procedures. Quantile regression illustrated the differential effect of serious SSIs on health care costs at the upper end of the cost distribution.

The links between protected areas, faiths, and sacred natural sites.

Most people follow and are influenced by some kind of spiritual faith. We examined two ways in which religious faiths can in turn influence biodiversity conservation in protected areas. First, biodiversity conservation is influenced through the direct and often effective protection afforded to wild species in sacred natural sites and in seminatural habitats around religious buildings. Sacred natural sites are almost certainly the world's oldest form of habitat protection. Although some sacred natural sites exist inside official protected areas, many thousands more form a largely unrecognized "shadow" conservation network in many countries throughout the world, which can be more stringently protected than state-run reserves. Second, faiths have a profound impact on attitudes to protection of the natural world through their philosophy, teachings, investment choices, approaches to land they control, and religious-based management systems. We considered the interactions between faiths and protected areas with respect to all 11 mainstream faiths and to a number of local belief systems. The close links between faiths and habitat protection offer major conservation opportunities, but also pose challenges. Bringing a sacred natural site into a national protected-area system can increase protection for the site, but may compromise some of its spiritual values or even its conservation values. Most protected-area managers are not trained to manage natural sites for religious purposes, but many sacred natural sites are under threat from cultural changes and habitat degradation. Decisions about whether or not to make a sacred natural site an "official" protected area therefore need to be made on a case-by-case basis. Such sites can play an important role in conservation inside and outside official protected areas. More information about the conservation value of sacred lands is needed as is more informed experience in integrating these into wider conservation strategies. In addition, many protected-area staff need training in how to manage sensitive issues relating to faiths where important faith sites occur in protected areas. ©2009 Society for Conservation Biology.

Inter-hemispheric language functional reorganization in low-grade glioma patients after tumour surgery.

2015-03-01

Despite many claims of functional reorganization following tumour surgery, empirical studies that investigate changes in functional activation patterns are rare. This study investigates whether functional recovery following surgical treatment in patients with a low-grade glioma in the left hemisphere is linked to inter-hemispheric reorganization. Based on literature, we hypothesized that reorganization would induce changes in the spatial pattern of activation specifically in tumour homologue brain areas in the healthy right hemisphere. An experimental group (EG) of 14 patients with a glioma in the left hemisphere near language related brain areas, and a control group of 6 patients with a glioma in the right, non-language dominant hemisphere were scanned before and after resection. In addition, an age and gender matched second control group of 18 healthy volunteers was scanned twice. A verb generation task was used to map language related areas and a novel technique was used for data analysis. Contrary to our hypothesis, we found that functional recovery following surgery of low-grade gliomas cannot be linked to functional reorganization in language homologue brain areas in the healthy, right hemisphere. Although elevated changes in the activation pattern were found in patients after surgery, these were largest in brain areas in proximity to the surgical resection, and were very similar to the spatial pattern of the brain shift following surgery. This suggests that the apparent perilesional functional reorganization is mostly caused by the brain shift as a consequence of surgery. Perilesional functional reorganization can however not be excluded. The study suggests that language recovery after transient post-surgical language deficits involves recovery of functioning of the presurgical language system. Copyright © 2014 Elsevier Ltd.

Enzyme superfamily members that share common chemical and/or biological functions also share common features. While the role of structure is well characterized, the link between enzyme function and dynamics is not well understood. We present a systematic characterization of intrinsic dynamics of over 20 members of the pancreatic-type RNase superfamily, which share a common structural fold. This study is motivated by the fact that the range of chemical activity as well as molecular motions of RNase homologs spans over 10 5 folds. Dynamics was characterized using a combination of nuclear magnetic resonance experiments and computer simulations. Phylogenetic clustering led to the grouping of sequences into functionally distinct subfamilies. Detailed characterization of the diverse RNases showed conserved dynamical traits for enzymes within subfamilies. These results suggest that selective pressure for the conservation of dynamical behavior, among other factors, may be linked to the distinct chemical and biological functions in an enzyme superfamily.

The authors examined the links between two dimensions that have been useful in understanding cross-cultural differences and similarities, namely, individualism-collectivism (I-C) and value orientations. The authors examined the relations and parallels between the two variables by directly relating them and examining the patterns of relations that both have with a third variable, religiosity. Participants were 475 college students from the Philippines, the United States, and Turkey who responded to measures of horizontal and vertical I-C, value orientations, and religiosity. The authors found partial support for the parallels between I-C and value types, particularly for collectivism and conservative values. Moreover, religiosity was associated positively with conservative values and collectivism, across all three cultures. The authors found individualism to also relate to openness-to-change values, though the patterns were not as consistent as those that they found between collectivism and conservation. Differences and similarities emerged in links of I-C-values to religiosity across the three samples.

[Urodynamic studies prior to urinary incontinence surgery : What is useful?

PubMed

Kaufmann, A

2017-12-01

Surgery is often necessary after failure of conservative therapy for urinary incontinence. Guidelines recommend urodynamic studies before surgery. A distinction is made between non-invasive (uroflowmetry) and invasive methods (cystometry and pressure-flow study, if necessary as combined videourodynamics, as well as urethral pressure profile). All examinations serve to objectify and quantify the symptoms, to correctly assign symptoms to the pathophysiology and anatomy as well as to identify risk factors, which often have a significant influence on the success of surgical therapy. Given appropriate experience, complications and often significant sequelae of bladder dysfunction affecting the patient's quality of life and life expectancy can be recognized. Urodynamic studies are performed to help narrow down potential diagnoses, to develop therapeutic strategies, and to obtain prognostic parameters. The following article is intended to provide some support.

The functional and aesthetic restoration of teeth compromised due to aggressive periodontitis presents numerous challenges for the clinician. Horizontal bone loss and soft tissue destruction resulting from periodontitis can impede implant placement and the regeneration of an aesthetically pleasing gingival smile line, often requiring bone augmentation and mucogingival surgery, respectively. Conservative approaches to the treatment of aggressive periodontitis (i.e., treatments that use minimally invasive tools and techniques) have been purported to yield positive outcomes. Here, we report on the treatment and five-year follow-up of patient suffering from aggressive periodontitis using a minimally invasive surgical technique and implant system. By using the methods described herein, we were able to achieve the immediate aesthetic and functional restoration of the maxillary incisors in a case that would otherwise require bone augmentation and extensive mucogingival surgery. This technique represents a conservative and efficacious alternative to the aesthetic and functional replacement of teeth compromised due to aggressive periodontitis. PMID:26649207

Body image of Greek breast cancer patients treated with mastectomy or breast conserving surgery.

The aim of this study was to assess and compare the body image of breast cancer patients (n = 70) whom underwent breast conserving surgery or mastectomy, as well as to compare patients' scores with that of a sample of healthy control women (n = 70). A secondary objective of this study was to examine the reliability and validity of the 10-item Greek version of the Body Image Scale, a multidimensional measure of body image changes and concerns. Exploratory and confirmatory factor analyses on the items of this scale resulted in a two factor solution, indicating perceived attractiveness, and body and appearance satisfaction. Comparison of the two surgical groups revealed that women treated with mastectomy felt less attractive and more self-conscious, did not like their overall appearance, were dissatisfied with their scar, and avoided contact with people. Hierarchical regression analysis showed that more general body image concerns were associated with belonging to the mastectomy group, compared to the cancer-free group of women. Implications for clinical practice and recommendations for future investigations are discussed.

The purpose of this study was to collect data regarding breast cancer profiles and factors that affect local recurrence and distant metastasis after breast-conserving surgery (BCS) in Chiang Mai University Hospital. This study was a retrospective review in a single institution of newly diagnosed invasive breast cancer patients who were treated with BCS between April 9, 2001 and December 25, 2011. A total of 185 patients treated with BCS were included in this study, with an average age of 46.83 years. The average recurrence age was 41.1 years and the average nonrecurrence age was 47.48 years, with a recurrence rate of 10.27%. Premenopause was significant in recurrence (P=0.047), as well as non-estrogen-expression patients (P=0.001) and patients who did not receive antihormonal treatment (P=0.011). The recurrence rate in our institute was 10.27%. Factors affecting recurrence after BCS included young age, premenopausal status, nonexpression of the estrogen receptor, and patients who had not received antihormonal treatment. The recurrence rate was higher in the first 90 postoperative months.

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.

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. 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. 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%. 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.

The objective of this study is to analyse local recurrence rates in patients receiving neoadjuvant chemotherapy (nCT) comparing mastecomized (MX) patients with those undergoing breast conserving therapy (BCT). Patients undergoing breast cancer surgery after nCT (3xCMF or 3-6xED) between 1995 and 2007 at our department were retrospectively analysed. The median follow up was 60 months for 308 patients. Patients who were downsized from MX to BCT with partial or complete response (n = 104) had a similar local recurrence free survival (LRFS) compared to patients who did not experience successful downsizing (n = 67) and finally undergoing MX (LRFS MX-BCT 81% vs. MX-MX 91%; P = 0.79). Uni- and multivariate analyses demonstrated that BCT itself was not an independent prognostic factor for a worse LRFS (P = 0.07 and 0.14). After no pathologic change or progressive disease the risk of local recurrence was increased in patients undergoing BCT (MX-BCT; n = 6 LRFS 66%) compared with MX (n = 44; LRFS 90%; P = 0.04). Overall survival in general was better for the BCT group (n = 197) compared with MX group (n = 111) regardless of clinical response (92% vs. 72%; P < 0.0001). Breast conservation, nodal negativity and low or medium grade histology were prognostic factors for an improved OS (P = 0.02, 0.01, 0.004). In conclusion, our study suggests that BCT is oncologically safe after tumour downsizing by nCT in patients primarily scheduled for mastectomy. These patients, however, should not be treated with breast conservation in the absence of any proven response after nCT.

Post-esophageal atresia anastomotic strictures and post-corrosive esophagitis are the most frequent types of cicatricial esophageal stricture. Congenital esophageal stenosis has been reported to be a rare but typical disease in children; other pediatric conditions are peptic, eosinophilic esophagitis and dystrophic recessive epidermolysis bullosa strictures. The conservative treatment of esophageal stenosis and strictures (ES) rather than surgery is a well-known strategy for children. Before planning esophageal dilation, the esophageal morphology should be assessed in detail for its length, aspect, number and level, and different conservative strategies should be chosen accordingly. Endoscopic dilators and techniques that involve different adjuvant treatment strategies have been reported and depend on the stricture's etiology, the availability of different tools and the operator's experience and preferences. Balloon and semirigid dilators are the most frequently used tools. No high-quality studies have reported on the differences in the efficacies and rates of complications associated with these two types of dilators. There is no consensus in the literature regarding the frequency of dilations or the diameter that should be achieved. The use of adjuvant treatments has been reported in cases of recalcitrant stenosis or strictures with evidence of dysphagic symptoms. Corticosteroids (either systemically or locally injected), the local application of mitomycin C, diathermy and laser ES sectioning have been reported. Some authors have suggested that stenting can reduce both the number of dilations and the treatment length. In many cases, this strategy is effective when either metallic or plastic stents are utilized. Treatment complications, such esophageal perforations, can be conservatively managed, considering surgery only in cases with severe pleural cavity involvement. In cases of stricture relapse, even if such relapses occur following the execution of well-conducted conservative strategies, surgical stricture resection and anastomosis or esophageal substitution are the only remaining options.

Pay for performance in thoracic surgery.

In the context of improving the quality of the medical practice, PFP programs have been developed to reward best medical practice. Early studies showed little gain in quality after implementing PFP family practice programs and some unintended consequences, like excluding high-risk patients from medical services when good outcomes were linked to payment. To date, no PFP programs have been implemented in surgical practice, but it is expected that value-based purchasing philosophy will be extended to surgical specialties in the near future. Quality initiatives in surgery can be based on outcome or process measures. Outcomes-focused quality approaches rely on accurate information obtained from multiinstitutional clinical databases for calculation of risk-adjusted models. Primary outcomes such surgical mortality are uncommon in modern thoracic surgery and outcome measures should rely on more prevalent intermediate outcomes such as specific postoperative morbidities or emergency readmission. Process-based quality approaches need to be based on scientific evidence linking process to outcomes. It is our responsibility to develop practice guidelines or international practice consensus to facilitate the parameters to be evaluated in the near future.

Musculoskeletal low back pain (LBP) is commonly treated symptomatically, with practice guidelines advocating reserving surgery for cases that fail conservative care. This study examined medical comorbidities and demographic variables as risk factors for chronic/recurrent LBP, spinal surgery, and time to surgery. A 2015 retrospective cohort study was conducted in U.S. Army soldiers (N=1,092,420) from 2002 to 2011. Soldiers with medical encounters for LBP were identified using ICD-9 codes. Surgical treatment for LBP was identified according to Current Procedural Terminology codes. Comorbid medical conditions (psychological disorders, sleep disorders, tobacco use, alcohol use, obesity) and demographic variables were examined as risk factors for chronic/recurrent LBP within 1 year of the incident encounter, surgery for LBP, and time to surgery. Of 383,586 patients with incident LBP, 104,169 (27%) were treated for chronic/recurrent LBP and 7,446 (1.9%) had surgery. Comorbid variables showed increased risk of chronic/recurrent LBP ranging from 26% to 52%. Tobacco use increased risk for surgery by 33% (risk ratio, 1.33; 95% CI=1.24, 1.44). Comorbid variables showed 10%-42% shorter time to surgery (psychological disorders, time ratio [TR]=0.90, 95% CI=0.83, 0.98; sleep disorders, TR=0.68, 95% CI=0.60, 0.78; obesity, TR=0.88, 95% CI=0.79, 0.98; tobacco use, TR=0.58, 95% CI=0.54, 0.63; alcohol use, TR=0.85, 95% CI=0.70, 1.05). Women showed 20% increased risk of chronic/recurrent LBP than men but 42% less risk of surgery. In the presence of comorbidities associated with mental health, sleep, obesity, tobacco use, and alcohol use, LBP shows increased risk of becoming chronic/recurrent and faster time to surgery.

Psychological factors in postoperative adjustment to stoma surgery.

White, C. A.; Hunt, J. C.

1997-01-01

Around one-quarter of stoma patients experience clinically significant psychological symptoms post-operatively. Psychological disorders are often not detected by those involved with the care of stoma patients. Past psychiatric history, dissatisfaction with preoperative preparation for surgery, postoperative physical symptomatology and the presence of negative stoma-related thoughts/beliefs have all been shown to be significantly associated with psychological morbidity after surgery. These findings suggest that healthcare professionals (especially surgeons involved with this patient population) should ask all patients about these factors before and after surgery. Questionnaires could be used to screen for difficulties and/or staff could undertake training aimed at improving the detection of psychological morbidity and endeavour to strengthen links with liaison mental health services. Future research in this area should be prospective, using psychometrically valid measures and be focused on the prediction, prevention, detection and treatment of poor psychological adjustment after stoma surgery.

Timely access to orthopedic trauma surgery is essential for optimal outcomes. Regionalization of some types of surgery has shown positive effects on access, timeliness and outcomes. We investigated how the consolidation of orthopedic surgery in 1 Canadian health region affected patients requiring hip fracture surgery. We retrieved administrative data on all regional emergency department visits for lower-extremity injury and all linked inpatient stays from January 2010 through March 2013, identifying 1885 hip-fracture surgeries. Statistical process control and interrupted time series analysis controlling for demographics and comorbidities were used to assess impacts on access (receipt of surgery within 48-h benchmark) and surgical outcomes (complications, in-hospital/30-d mortality, length of stay). There was a significant increase in the proportion of patients receiving surgery within the benchmark. Complication rates did not change, but there appeared to be some decrease in mortality (significant at 6 mo). Length of stay increased at a hospital that experienced a major increase in patient volume, perhaps reflecting challenges associated with patient flow. Regionalization appeared to improve the timeliness of surgery and may have reduced mortality. The specific features of the present consolidation (including pre-existing interhospital performance variation and the introduction of daytime slates at the referral hospital) should be considered when interpreting the findings.

Pulsed Radiofrequency Ablation for Treating Sural Neuralgia.

PubMed

Abd-Elsayed, Alaa; Jackson, Markus; Plovanich, Elizabeth

2018-01-01

Sural neuralgia is persistent pain in the distribution of the sural nerve that provides sensation to the lateral posterior corner of the leg, lateral foot, and fifth toe. Sural neuralgia is a rare condition but can be challenging to treat and can cause significant limitation. We present 2 cases of sural neuralgia resistant to conservative management that were effectively treated by pulsed radiofrequency ablation. A 65-year-old female developed sural neuralgia after a foot surgery and failed conservative management. She had successful sural nerve blocks, and pulsed radiofrequency ablation led to an 80% improvement in her pain. A 33-year-old female presented with sural neuralgia secondary to two falls. The patient had tried several conservative modalities with no success. We performed diagnostic blocks and pulsed radiofrequency ablation, and the patient reported 80% improvement in her pain. Pulsed radiofrequency ablation may be a safe and effective treatment for patients with sural neuralgia that does not respond to conservative therapy. However, studies are needed to elucidate its effectiveness and safety profile.

Representations of cosmetic surgery and emotional health in women's magazines in Canada.

PubMed

2008-01-01

This research examines how popular women's magazines portray cosmetic surgery and associated emotional health. Articles regarding cosmetic surgery were coded from the top five most circulated English-language women's magazines in Canada between 2002 and 2006 for type of procedure, patient demographics, risk information, and indicators of emotional health. Content analysis techniques were used to identify patterns of portraying the risks and benefits of cosmetic surgery. Content analyses show the articles tend to present readers with detailed physical health risk information. However, 48% of articles discuss the impact that cosmetic surgery has on emotional health, most often linking cosmetic surgery with enhanced emotional well-being regardless of the patient's pre-existing state of emotional health. The articles also tend to use accounts given by males to provide defining standards of female attractiveness. These findings are consistent with arguments in the research literature that women's magazines contribute to the medicalization of the female body. Cosmetic surgery is generally portrayed as a risky--but worthwhile--option for women to enhance both their physical appearance and emotional health. The implications for future research and public education strategies are discussed.

Production of Entanglement Entropy by Decoherence

NASA Astrophysics Data System (ADS)

Merkli, M.; Berman, G. P.; Sayre, R. T.; Wang, X.; Nesterov, A. I.

We examine the dynamics of entanglement entropy of all parts in an open system consisting of a two-level dimer interacting with an environment of oscillators. The dimer-environment interaction is almost energy conserving. We find the precise link between decoherence and production of entanglement entropy. We show that not all environment oscillators carry significant entanglement entropy and we identify the oscillator frequency regions which contribute to the production of entanglement entropy. For energy conserving dimer-environment interactions the models are explicitly solvable and our results hold for all dimer-environment coupling strengths. We carry out a mathematically rigorous perturbation theory around the energy conserving situation in the presence of small non-energy conserving interactions.

Sialendoscope-assisted transoral removal of hilo-parenchymal sub-mandibular stones: surgical results and subjective scores.

Capaccio, P; Gaffuri, M; Rossi, V; Pignataro, L

2017-04-01

It has been suggested that a conservative trans-oral approach to proximal and hilo-parenchymal submandibular stones (HPSMS) is a valid alternative to the more frequently used sialadenectomy. The aim of this study was to evaluate the surgical, ultrasonographic and patients' subjective outcomes of results of the trans-oral removal of HPSMS. Between January 2003 and September 2015, sialendoscope-assisted trans-oral surgery was used to remove symptomatic, large (> 7 mm), fixed and palpable HPSMS from 479 patients under general anaesthesia. All patients were followed clinically and ultrasonographically to investigate symptom relief and recurrence of stones, and were telephonically interviewed to assess saliva-related subjective outcomes with a questionnaire. Stones were successfully removed from 472 patients (98.5%); the seven failures (1.5%) concerned pure parenchymal stones. One year after the procedure, 408 patients (85.1%) were symptom free, 59 (12.3%) had recurrent obstructive symptoms and 12 (2.6%) had recurrent infections. Of the 54 patients who developed a recurrent stone (11.2%), 52 underwent a second procedure: 29 interventional sialendoscopies, two sialendoscope-assisted intra-corporeal pneumatic lithotripsy, eight secondary transoral surgery to remove residual stones, six a cycle of extra-corporeal lithotripsy and seven submandibular sialadenectomy. Most patients (75.2%) reported mild surgery-related pain. The symptoms of 454 patients (94.8%) improved after adjunctive treatment and, at the end of follow-up, the affected gland was preserved in 98.5% of patients. A sialendoscope-assisted trans-oral removal of large HPSMS is a safe, effective, conservative surgical procedure, and functional preservation of the main duct and parenchyma of the obstructed gland allows sialendoscopic access through the natural ostium in case of recurrence. Combining a trans-oral approach with other minimally invasive, conservative procedures ensures symptomatic relief and salivary duct system clearance in the majority of patients. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale, Rome, Italy.

The late side-effects of the local therapy of early breast cancer depend on many patient- and therapy-related parameters. We aimed at investigating the factors that influence the cosmetic and functional outcomes among our breast cancer patients after breast-conserving surgery and conformal radiotherapy, with or without adjuvant systemic therapy. A study was made of the association of the cosmetic outcome after a median follow-up time of 2.4 years and the clinical data on 198 patients extracted from a prospectively compiled database. Breast tenderness occurred more frequently among patients ≤50 years old (p < 0.05). Long-term side effects were related to radiotherapy-related factors the most, while no effect of the systemic therapy could be detected. The risk of hyperpigmentation, breast edema and breast fibrosis increased by 18%, 23% and 7%, respectively for every 100 cm(3) increase in the irradiated breast volume, while that of breast edema and breast fibrosis increased by 21% and 12%, respectively for every 10 cm(3) increase in the boost volume. Patients who received a photon boost were significantly more likely to develop breast edema and fibrosis than those who received electrons (p < 0.005). Dose inhomogeneity was related to the volume of the irradiated breast (p = 0.037). Dyspigmentation developed more often among patients older than 50 years, while smoking favoured both dyspigmentation and teleangiectasia. Breast edema was related to dyspigmentation (p = 0.003), fibrosis (p < 0.001) and breast asymmetry (p = 0.032), whereas none of these abnormalities were associated with teleangiectasia. Body image changes were more frequent at a younger age (p < 0.005), while the need to change clothing habits occurred more often at an older age (p < 0.05). Radiotherapy-related parameters appear to exert the greatest effect on the overall cosmetic outcome after breast-conserving surgery and postoperative radiotherapy.

Sonography in patients with gunshot wounds of the scrotum: imaging findings and their value.

Learch, T J; Hansch, L P; Ralls, P W

1995-10-01

The purposes of this study were to characterize sonographic findings in patients with scrotal injuries caused by gunshot wounds and to determine if sonography can be used to detect and differentiate various scrotal abnormalities. If patients are managed conservatively, less serious injuries (hydroceles, hematoceles, and scrotal hematomas) must be separated from those requiring urgent surgical repair (testicular rupture). Sonograms obtained in 19 patients to evaluate gunshot wounds to the scrotum were studied for evidence of testicular rupture, extratesticular soft-tissue abnormalities, and the presence and location of foreign bodies. The results were compared with clinical (19 patients) and surgical (six patients) findings. Retrospective review of the sonograms showed normal testicles without evidence of rupture in 11 patients, eight of whom had scrotal hematomas, hydroceles, or hematoceles. Nine of the 11 patients were treated conservatively, and their symptoms resolved. In one of the other two patients, a prominent vessel was initially mistaken for a fracture plane; the testicle was found to be intact at surgery. The other patient was taken to surgery to remove a bullet in the peritesticular soft tissues; surgery demonstrated intact, viable testicles bilaterally, but both epididymides had through-and-through tracts from the bullet. Two patients had sonolucent tracks from missile pathways in otherwise normal appearing testicles. Testicular rupture was sonographically detected in six patients. Sonograms in all patients with surgically confirmed testicular rupture showed heterogeneous echogenicity and loss of smooth oval contour. In one patient, the sonogram showed a fracture plane. Sonograms showed foreign bodies in five patients and localized them to the testicular parenchyma (one patient) and to extratesticular soft tissues (four patients). Sonography can distinguish various scrotal abnormalities caused by ballistic trauma, information that can be useful to the urologist if conservative management is considered. Sonography can be used to distinguish less serious injuries such as scrotal hematomas, hydroceles, and hematoceles from surgical emergencies such as testicular rupture. Foreign body presence and location can also be determined. Epididymal injuries were not well visualized.

The purpose of this retrospective study was to evaluate the effect of pre-operative planning using real-time virtual sonography (RVS), a magnetic resonance imaging (MRI)/ultrasound (US) image fusion technique on breast-conserving surgery (BCS) in patients with non-mass enhancement (NME) on breast MRI. Between 2011 and 2015, we enrolled 12 consecutive patients who had lesions with NME that exceeded the US hypo-echoic area, in which it was particularly difficult to evaluate the tumor margin. During pre-operative planning before breast-conserving surgery, RVS was used to delineate the enhancing area on the breast surface after additional supine breast MRI was performed. We analyzed both the surgical margin positivity rate and the re-operation rate. All NME lesions corresponded to the index cancer. In all patients, the diameter of the NME lesion was greater than that of the hypo-echoic lesion. The median diameters of the NME and hypo-echoic lesions were 24 mm (range: 12-39 mm) and 8.0 mm (range: 4.9-18 mm), respectively (p = 0.0002). After RVS-derived skin marking was performed on the surface of the affected breast, lumpectomy and quadrantectomy were conducted in 7 and 5 patients, respectively. The surgical margins were negative in 10 (83%) patients. Two patients with positive margins were found to have ductal carcinoma in situ in 1 duct each, 2.4 and 3.2 mm from the resection margin, respectively. None of the patients required additional resection. Although further prospective studies are required, the findings of our preliminary study suggest that it is very well possible that the use of RVS-derived skin marking during pre-operative planning for BCS in patients with NME would have resulted in surgical outcomes similar to or better than those obtained without the use of such marking.

Extracranial-to-intracranial (EC-IC) bypass surgery may be necessary in patients with moyamoya disease and other ischemic conditions. However, there is a potential risk of wound-related complications in some cases. In this study, we report our approach to prevention of wound-related complications in EC-IC bypass, and technical consideration and pitfalls of surgery are discussed. This study included 89 patients with ischemic-onset moyamoya disease and atherosclerotic disease, who underwent 108 superficial temporal artery (STA)-to-middle cerebral artery bypass procedures. Our study emphasized 3 major features. First, 3-dimensional simulation imaging was used to confirm STA anatomy. Second, the STA was meticulously dissected on the epigaleal layer, and protected the galeal layer. Third, scalp skin ischemia was taken into consideration at each step until skin closure. There was no neurological morbidity or mortality in this series. There were 2 cases with major wound-related complications that needed plastic surgical intervention, and 4 cases with minor complications that were treated conservatively. In major complication cases, the scalp defect was treated with pedicle flap reconstruction. In EC-IC bypass surgery, interdisciplinary management involving neurosurgery, plastic surgery, and radiology should reduce wound-related complications, and achieve safe surgery.

We report a patient who had rhinogenic intracranial complication with postoperative frontal sinus pyocele and inverted papilloma in the nasal cavity. A 72-year-old woman had undergone surgery for frontal sinusitis via external incision at another hospital 13 years previously. Left-sided hemiparesis appeared in the patient and gradually worsened. Five days later, she exhibited disorientation, abnormal behavior, poor articulation, and difficulty in standing. Therefore, she was taken to the neurosurgery department by ambulance. An extensive frontal sinus pyocele was suspected, and a cerebral abscess and edema of the frontal lobe were observed on magnetic resonance imaging. After antibiotics, steroid and glycerol were administered for a few weeks; disorientation and left hemiparesis improved. Next, craniotomy for complete removal of the brain abscess by neurosurgeons and endoscopic endonasal surgery by otolaryngologists were carried out at the same surgery. From the analysis of the pathological mucosa sample taken from the right ethomoidal sinus during surgery, an inverted papilloma was diagnosed. The patient completely recovered and is currently receiving follow-up examination. Regarding rhinogenic intracranial complications, ascertaining clinical condition in order to determine the need for either immediate radical surgery, or for curative surgery after waiting for improvement of the overall body condition by conservative management, is still needed.

Background: Oncoplastic Breast Surgery (OBS), which is a combination of oncological procedures and plastic surgery techniques, has recently gained widespread use. Aims: To assess the experiences, practice patterns and preferred approaches to Oncoplastic and Reconstructive Breast Surgery (ORBS) undertaken by general surgeons specializing in breast surgery in Turkey. Study Design: Cross-sectional study. Methods: Between December 2013 and February 2014, an eleven-question survey was distributed among 208 general surgeons specializing in breast surgery. The questions focused on the attitudes of general surgeons toward performing oncoplastic breast surgery (OBS), the role of the general surgeon in OBS and their training for it as well as their approaches to evaluating cosmetic outcomes in Breast Conserving Surgery (BCS) and informing patients about ORBS preoperatively. Results: Responses from all 208 surgeons indicated that 79.8% evaluated the cosmetic outcomes of BCS, while 94.2% informed their patients preoperatively about ORBS. 52.5% performed BCS (31.3% themselves, 21.1% together with a plastic surgeon). 53.8% emphasized that general surgeons should carry out OBS themselves. 36.1% of respondents suggested that OBS training should be included within mainstream surgical training, whereas 27.4% believed this training should be conducted by specialised centres. Conclusion: Although OBS procedure rates are low in Turkey, it is encouraging to see general surgeons practicing ORBS themselves. The survey demonstrates that our general surgeons aspire to learn and utilize OBS techniques. PMID:25667784

To investigate the incidence and predictive factors of 30-day surgery-related morbidity and occult precancerous and cancerous conditions for women undergoing risk-reducing surgery. A prospective study (Canadian Task Force classification II-1). A gynecologic oncology referral center. Breast-related cancer antigen (BRCA) mutation carriers and BRCAX patients (those with a significant family history of breast and ovarian cancer). Minimally invasive risk-reduction surgery. Overall, 85 women underwent risk-reducing surgery: 30 (35%) and 55 (65%) had hysterectomy plus bilateral salpingo-oophorectomy (BSO) and BSO alone, respectively. Overall, in 6 (7%) patients, the final pathology revealed unexpected cancer: 3 early-stage ovarian/fallopian tube cancers, 2 advanced-stage ovarian cancers (stage IIIA and IIIB), and 1 serous endometrial carcinoma. Additionally, 3 (3.6%) patients had incidental finding of serous tubal intraepithelial carcinoma. Four (4.7%) postoperative complications within 30 days from surgery were registered, including fever (n = 3) and postoperative ileus (n = 1); no severe (grade 3 or more) complications were observed. All complications were managed conservatively. The presence of occult cancer was the only factor predicting the development of postoperative complications (p = .02). Minimally invasive risk-reducing surgery is a safe and effective strategy to manage BRCA mutation carriers. Patients should benefit from an appropriate counseling about the high prevalence of undiagnosed cancers observed at the time of surgery. Copyright © 2017 AAGL. Published by Elsevier Inc.

Effects of disputes and easement violations on the cost-effectiveness of land conservation

PubMed Central

Arcese, Peter

2015-01-01

Conservation initiatives to protect and restore valued species communities in human-dominated landscapes face challenges linked to their potential costs. Conservation easements on private land may represent a cost-effective alternative to land purchase, but long-term costs to monitor and enforce easements, or defend legal challenges, remain uncertain. We explored the cost-effectiveness of conservation easements, defined here as the fraction of the high-biodiversity landscape potentially protected via investment in easements versus land purchase. We show that easement violation and dispute rates substantially affect the estimated long-term cost-effectiveness of an easement versus land purchase strategy. Our results suggest that conservation easements can outperform land purchase as a strategy to protect biodiversity as long as the rate of disputes and legal challenges is low, pointing to a critical need for monitoring data to reduce costs and maximize the value of conservation investments.

Medicaid beneficiaries with cancer are less likely to receive timely and high-quality care. This study examined whether differences in state-level Medicaid policies affect delays in time to surgery (TTS) among women diagnosed with breast cancer. Using 2006-2008 Medicaid data, we identified women aged 18-64 enrolled in Medicaid diagnosed with breast cancer. Analyses examined associations of state-specific Medicaid surgery reimbursements, Medicaid eligibility recertification period (annually vs. shorter) and required patient copayment on time from breast cancer diagnosis to receipt of breast surgery. Patients receiving neoadjuvant therapy were excluded. Separate multivariable regression analyses controlling for patient demographic characteristics and clustering by state were performed for breast conserving surgery (BCS), inpatient mastectomy, and outpatient mastectomy. The study included 7542 Medicaid beneficiaries with breast cancer: 3272 received BCS, 2156 outpatient mastectomy, and 2115 inpatient mastectomy. Higher Medicaid reimbursements for BCS were associated with decreased time from diagnosis to surgery. A 12-month (vs. <12 month) Medicaid eligibility recertification period was associated with decreased TTS for BCS and outpatient mastectomy. Black Medicaid beneficiaries (compared with non-Hispanic White beneficiaries) were more likely to experience delays for all three types of surgery, while Hispanic beneficiaries were more likely to experience delays only for outpatient mastectomy. State-level Medicaid policies and patient characteristics can affect receipt of timely surgery among Medicaid beneficiaries with breast cancer. As delays in surgery can increase morbidity and mortality, changes to state Medicaid policies and health system programs are needed to improve access to care for this vulnerable population.

To determine if imaging findings on computed tomography (CT) can predict the need of surgery in patients with idiopathic mesenteric phlebosclerosis (IMP).This retrospective study included 28 patients with IMP. Abdominal CT images were reviewed to determine the extent and severity of mesenteric calcifications and the presence of findings related to colitides. We compared the number of colonic segments with mesenteric venous calcification, a total calcification score, and the rate of colonic wall thickening, pericolic fat stranding, and bowel loop dilatation between patients undergoing surgery (surgery group) and patients without surgery (nonsurgery group). Comparisons were made using the Mann-Whitney U test and Fisher exact test. Receiver operating characteristic analysis was also performed. Inter-reader agreement for the calcification scores was analyzed using kappa statistics.The number of colonic segments with mesenteric venous calcification and the total calcification scores were both significantly higher in the surgery group than the nonsurgery group (4.33 vs 2.96, P = 0.003; and 15.00 vs 8.96, P <0.001). The areas under the receiver operating characteristics to identify patients who need surgery were 0.96 and 0.92, respectively. The prevalence of bowel loop dilatation in the surgery group was also significantly higher than that in the nonsurgery group (16% vs 100%, P = 0.011).Evaluation of the severity and extent of IMP based on the total mesenteric venous calcification score, number of involved colonic segments, and the presence bowel loop dilatation on CT may be useful to indicate the outcomes of conservative treatment and need for surgery.

Endocan has been shown to be a marker for several cancers and may show degree of malignancy. The aim of this study is to assess serum levels of endocan before and after surgery on low-grade gliomas (LGGs). Endocan was assayed by commercially available enzyme-linked immunosorbent assay (ELISA) kits in a total of 19 patients and 12 controls. Serial serum samples were obtained before and after surgery (1 st day, 1 st week, and 1 st month of surgery). Control samples were collected from cord blood during cesarean section. The results were compared with control brain tissues. Controls showed significantly lower serum endocan levels compared to before and after surgery ( P < 0.05). There is a trend of increase in mean serum levels from before surgery and during the very early period after surgery (during first week); however, in the first month, mean serum levels became lower. Endocan, a vital molecule for angiogenesis, is highly expressed before and after surgery in LGGs, but long-term data is needed. Furthermore, future studies should include high-grade gliomas to discuss whether endocan is associated with recurrence and response to treatment.

The appearance of gastrografin in colon within 6 hours after gastric administration rules out the need of surgery in abdominal subileus. This diagnostic management is not routinely applied in children. We present a one-year experience from the department of pediatric surgery. Between April 2006 and September 2007 children with symptoms of ileus without clear indications for surgery were subjected to the study. Naso-gastric tube was inserted and 20-100 cc of gastrografin was administered. Abdominal radiograph was taken within 4-6 hours. The presence of contrast in colon allowed for conservative management. All remaining children were subjected to surgery. Newborns and children with intussusception or incarcerated hernia were ruled out of the study. The study was implemented in 8 girls and 7 boys ranking in the age between 1 and 17 (mean 11) years. Thirteen children had postoperative obstruction (8 after appendectomy, 5 after other laparotomy). Two children (with Crohn disease and Schoenlein-Henoch purpura) were not operated before. Four children without appearance of contrast in colon were operated. None of the remaining eleven children required surgical intervention. This management is safe and effective. It brings forward decision for surgery and shortens observation in children who don't require surgical intervention.

Bird Diversity, Birdwatching Tourism and Conservation in Peru: A Geographic Analysis

In the face of the continuing global biodiversity loss, it is important not only to assess the need for conservation, through e.g. gap analyses, but also to seek practical solutions for protecting biodiversity. Environmentally and socially sustainable tourism can be one such solution. We present a method to spatially link data on conservation needs and tourism-based economic opportunities, using bird-related tourism in Peru as an example. Our analysis highlighted areas in Peru where potential for such projects could be particularly high. Several areas within the central and northern Andean regions, as well as within the lowland Amazonian regions of Madre de Dios and Loreto emerge as promising for this type of activity. Mechanisms to implement conservation in these areas include e.g. conservation and ecotourism concessions, private conservation areas, and conservation easements. Some of these mechanisms also offer opportunities for local communities seeking to secure their traditional land ownership and use rights. (Spanish language abstract, Abstract S1). PMID:22132078
