Background The purpose of this study was to evaluate the optimal timing and measures of the sinus tarsi approach for calcaneus fractures to avoid iatrogenic injury of the sural nerve and to assess for wound complications. A case series of 53 patients with calcaneus fractures treated by a single surgeon with the sinus tarsi approach was retrospectively analyzed. On the basis of the delay time from injury to surgery, patients were classified into 4 groups: immediate (0-3 days), early (4-6 days), intermediate (7-14 days), and late (14-18 days). All patients were followed for at least 1 year to observe wound conditions. The rate of wound complications and iatrogenic sural nerve injury was described. Incisions were classified into 2 groups: group A included patients with incisions extending posterior to the lateral malleolus, and group B included patients with incisions confined anterior to the lateral malleolus. The rates of nerve injury were compared between both groups. Forty-three patients with 52 Sanders type II fractures were included. The average time to surgery from injury was 8.8 days (range, 0-18 days). The overall postoperative rate of wound complications was 5.8% (3 of 52). In the immediate group, deep infections and wound necrosis were found in 2 of 8 fractures (25%). In the early group, 1 of 15 fractures developed superficial infection (6.7%). In the intermediate and late groups, no wound complication was identified. Iatrogenic sural nerve injury was recorded in 5 of 52 patients (9.6%). Group A had 33% (4 of 12) nerve injuries and group B had 2.5% (1 of 40) ( P = .009). In 70% of cases, a main branch of the sural nerve was directly under the incision. The sinus tarsi approach was generally effective and safe for calcaneus fractures. However, it was relatively risky to perform open reduction and internal fixation by the sinus tarsi approach within 6 days of injury. Because the sural nerve is in the vicinity of the approach, iatrogenic injury should be avoided by the use of careful planning and meticulous manipulations.

Implantation of Ahmed glaucoma valve is an effective surgical technique to reduce intraocular pressure in patients affected with glaucoma. While in the past, the use of this device was reserved to glaucoma refractory to multiple filtration surgical procedures, up-to-date mounting experience has encouraged its use also as a primary surgery for selected cases. Implantation of Ahmed glaucoma valve can be challenging for the surgeon, especially in patients who already underwent previous multiple surgeries. Several tips have to be acquired by the surgeon, and a long learning curve is always needed. Although the valve mechanism embedded in the Ahmed glaucoma valve decreases the risk of postoperative hypotony-related complications, it does not avoid the need of a careful follow-up. Complications related to this type of surgery include early and late postoperative hypotony, excessive capsule fibrosis around the plate, erosion of the tube or plate edge, and very rarely infection. The aim of this review is to describe surgical technique for Ahmed glaucoma valve implantation and to report related complications.

Our goal was to determine the optimal timing for repair of bile duct injuries sustained during cholecystectomy. Bile duct injury during cholecystectomy is a serious complication that often requires surgical repair. There is heterogeneity in the literature regarding the optimal timing of surgical repair, and it remains unclear to what extent timing determines postoperative morbidity and long-term anastomotic function. A single institution prospective database was queried for all E1 to E4 injuries from 1989 to 2014 using a standardized tabular reporting format. Timing was stratified into 3 groups [early (<7 days), intermediate (8 days until 6 weeks), and late (>6 weeks) after injury]. Analysis was stratified between those who had a previous bile duct repair or not, including postoperative complications and anastomotic failure as outcome variables in 2 separate multivariate logistic regression models. There were 614 patients included in the study. The mean age was 41 years (range, 15-85 yrs), and the majority were female (80%). The mean follow-up time was 40.5 months. Side-to-side hepaticojejunostomy was performed in 94% of repairs. Intermediate repair was associated with a higher risk of postoperative complications [odd ratio = 3.7, 95% confidence interval (1.3-10.2), P = 0.01] when compared with early and late in those with a previous repair attempt. Sepsis control and avoidance of biliary stents were protective factors against anastomotic failure. Adequate sepsis control and delayed repair of biliary injuries should be considered for patients presenting between 8 days and 6 weeks after injury to prevent complications, if a previous bile duct repair was attempted.

Management of pyothorax.

PubMed

Holmberg, D L

1979-05-01

Pyothorax is a serious disease process which requires both medical and surgical intervention. Late recognition, management problems, and likely recurrence make successful treatment difficult and often frustrating. Aims of therapy should be to avoid undue stress to the patient, to relieve respiratory distress by thoracocentesis, to eliminate infectious agents with antimicrobials, to remove pleural exudate, and to provide supportive care. Close monitoring of the patient is necessary to prevent iatrogenic complications such as pneumothorax, hemothorax, hypothermia, or hypoproteinemia. Exploratory thoracotomy for removal of granulomatous material and fibroelastic pleural "peels" is occasionally necessary to resolve compressive cardiopulmonary lesions.

[Suprapubic urinary diversion using Cystofix--an alternative to the urethral indwelling catheter].

PubMed

Müller, J; Sulmoni, M

1992-01-01

Suprapubic Cystofix-cystostomy is a valuable alternative to the Foley-catheter. The advantages of suprapubic cystostomy are mainly a reduction of urinary tract infections, inflammatory reactions in the lower urinary tract and avoidance of late urethral strictures after transurethral catheterism. There are a few contraindications to be considered, mainly an empty bladder and coagulation disorders. The complication rate of suprapubic Cystofix-cystostomy, usually gross haematuria, is very low. Cystofix-cystostomy is as useful for short term urinary drainage as for long term drainage in the case of chronic voiding disorders.

The purpose was to determine late complication incidence for pelvic palliation using accelerated multiple daily fraction radiation [Radiation Therapy Oncology Group (RTOG) 8502]. None of the patients with < 30 Gy (less than three courses) developed late toxicity. A total of 11/193 (6%) developed Grade 3+ late toxicity (nine Grade 3, on Grade 4, one Grade 5). Actuarial analysis of complication rate by survival time for Grades 3, 4, and 5 shows a cumulative incidence for complications after 6 months that plateaus at 6.9% by 18 months. The cumulative incidence for Grades 4 and 5 is 2.0% by 12 months.more » The difference in late effect for the 2-week rest vs. 4-week rest was not statistically different (p = .47). Patient factors evaluated for increased risk of late complications included prior surgeries, age, sex, KPS and primary. None were found to have significant statistical correlations with late effects. The crude late complications rate is 6%. Actuarial analysis using cumulative incidence shows 6.9% by 18 months. This represents a significant decrease in late complications from 49% seen with higher dose per fraction (10 Gy {times} 3) piloted by Radiation Therapy Oncology Group (7905) for a similar group of patients. Long-term analysis of late complication indicates this schedule can be used in the pelvis with relatively low incidence of complication. This schedule has significant logistic benefits and has been shown to produce good tumor regression and excellent palliation of symptoms. 14 refs., 4 figs., 4 tabs.« less

When external beam radiation therapy is administered to the pelvis, normal tissues irradiated may include the colon, small intestine, urethra, bladder, bone, and spinal cord. The objectives of this retrospective study were to determine the incidence and severity of late radiation effects following pelvic irradiation in dogs and to identify factors that increase the risk of these effects. Medical records of all dogs treated with curative intent external beam radiation therapy to the pelvic region between 1993 and 1999 were reviewed. Patients with follow-up longer than 9 months or any patient that developed late complications earlier than 9 months were evaluated. Sixteen dogs met criteria for inclusion in this study. All dogs were treated with a 6-MV linear accelerator with bilaterally opposed beams. Diseases treated included transitional cell carcinoma of the bladder, transitional cell carcinoma of the prostate, and anal sac apocrine gland adenocarcinoma. Four dose/fractionation schemes were used: 49.5 Gy in 3.3 Gy fractions, 54 Gy in 3.0 Gy fractions, 54 Gy in 2.7 Gy fractions, and 18 Gy intraoperative radiation therapy followed by 43 Gy external beam radiation therapy in 2.9 Gy fractions. Implantable chemotherapy in the form of an OPLA-Pt sponge was used in six dogs as a radiation potentiator. Colitis was the major late effect following pelvic irradiation, occurring in nine dogs (56%). Colitis was characterized as mild in three dogs, moderate in one dog, and severe in five dogs. Three of the dogs with severe effects suffered gastrointestinal perforation. All dogs with severe late effects received 3 or 3.3 Gy per fraction, and 80% received radiation potentiators. In the seven dogs that received 2.7 Gy or 2.9 Gy per fraction, late effects were classified as none (n = 5), mild colitis (n = 1), and moderate colitis (n = 1). Radiation therapy can be administered to the pelvic region with a minimal risk of late effects to the colon by giving smaller doses per fraction and avoiding systemic radiation potentiators.

Editorial Commentary: Graft Removal Versus Retention for Septic Arthritis After Anterior Cruciate Ligament Reconstruction: Accounting for Patient Preference Flips the Script on Current Practice.

PubMed

Cote, Mark P

2018-03-01

Septic arthritis is a rare but potentially devastating complication after anterior cruciate ligament (ACL) reconstruction. Studies examining surgical treatment options including graft retention and removal are largely inconclusive. Although the literature indicated that 43.8% of patients who have the graft removed later go on to have a revision ACL reconstruction compared with only 6.5% among those whose graft is retained, this expected-value decision analysis found removal to be the optimal treatment for patients with septic arthritis after ACL reconstruction. This is largely based on patient preference to avoid a late reoperation for residual knee infection. These findings support the concept of utility when considering treatment options for patients with a septic knee. For some, avoiding a late reoperation for a persistent infection is the most important factor and as such graft removal may be the most appropriate treatment to produce a positive outcome among these patients despite the fact that currently, an attempt at graft retention could represent the generally preferred treatment option among practicing surgeons.

2016-01-01

ABSTRACT Glaucoma surgeries targeting the uveoscleral drainage pathways have been drawing more attention lately. Among all the available techniques, procedures focusing on the supra-choroidal space seem particularly promising, by making use of a presumably efficient and secure outflow route and avoiding subconjunctival filtration blebs. The purpose of this review is to assess the efficacy and the security of the different suprachoroidal drainage implants, namely the CyPass Micro-Stent, the iStent Supra, the SOLX Gold Shunt, the Aquashunt, and the STARflo Glaucoma Implant. Most clinical studies seem to currently point toward the direction that there are actual benefits in suprachoroidal surgeries by avoiding bleb-related complications. Nevertheless, even suprachoroidal implants may be subject to scarring and failure. More data are still needed, especially concerning long-term effects, although the approach does seem appealing.

The present study reports a case of late mandibular fracture due to third molar extraction and highlights the inherent clinical, ethical and legal aspects related to this surgical complication. A female patient underwent surgical procedure for the extraction of the mandibular right third molar. Two days after the surgery the patient reported pain and altered occlusion in the right side of the mandible. After clinical and radiographic re-examination, the diagnosis of late mandibular fracture was established. A second surgery, under general anaesthesia, was performed for the fixation of the mandibular bone. The fractured parts were reduced and fixed with locking plate systems and 2 mm screws following load-sharing principles. The masticatory function showed optimal performance within 7 and 21 days after the surgery. Complete bone healing was observed within 1 year of follow-up. For satisfactory surgical outcomes, adequate surgical planning and techniques must be performed. Signed informed consents explaining the risks and benefits of the treatment must be used to avoid ethical and legal disputes in dentistry.

In this study, we initiated a prospective, randomised, clinical trial comparing the AMBI, TGN and PFN operations used for treatment of unstable fractures, for differences in intra-operative use, consolidation, complications and functional outcome. We have compared the pre-, intra- and post-operating variables of AMBI, TGN and PFN operations that were used for treatment of unstable trochanteric fractures, of 120 patients all above 60 years old diagnosed with extracapsular hip fractures classified as AO Type 31-A2 or Type 31-A3. According to our results the three methods are comparable in the treatment of unstable trochanteric fractures of patients above 60 years old. The AMBI remains the gold standard for the fractures of trochanteric region. TGN has an easier and faster procedure, facilitates early weight bearing and had minor late complications. An improper use of the PFN system was the reason for the most complications and the longer operation time of the device. PFN is also an accepted minimally invasive implant for unstable proximal femoral fractures but future modification of the implant to avoid Z-effect phenomenon, careful surgical technique and selection of the patients should reduce its high complication rate.

An accurate diagnosis of acute appendicitis is important to avoid severe outcome or unnecessary surgery but management is controversial. The aim of study was to evaluate, in younger and older children, the efficacy of conservative management for uncomplicated appendicitis and the outcome of complicated forms underwent early surgery. Children with acute appendicitis were investigated by clinical, laboratory variables and abdominal ultrasound and divided in two groups: complicated and uncomplicated. Complicated appendicitis underwent early surgery; uncomplicated appendicitis started conservative treatment with antibiotic. If in the next 24-48h it was worsening, the conservative approach failed and patients underwent late surgery. A total of 362 pediatric patients were included. One hundred sixty-five underwent early appendectomy; 197 patients were at first treated conservatively: of these, 82 were operated within 24-48h for failure. The total percentage of operated patients was 68.2%. An elevated association was found between surgery and ultrasound. Conservative treatment for uncomplicated appendicitis had high percentage of success (58%). Complications in operated patients were infrequent. Our protocol was effective in order to decide which patients treat early surgically and which conservatively; specific red flags (age and onset) can identified patients at most risk of complications or conservative failure. treatment study.

Compared to emergency surgery, self-expandable metallic stents are effective and safe when used as bridge-to-surgery (BTS) in operable patients with acute colorectal cancer obstruction. In this study, we report data on the new conformable colonic stents. To evaluate clinical effectiveness of conformable stents as BTS in patients with acute colorectal cancer obstruction. This was a retrospective study. The study was conducted at six Italian Endoscopic Units. Data about patients with acute malignant colorectal obstruction were collected between 2007 and 2012. All patients were treated with conformable stents as BTS. Technical success, clinical success, rate of primary anastomosis and colostomy, early and late complications were evaluated. Data about 88 patients (62 males) were reviewed in this study. Conformable SEMS were correctly deployed in 86 out of 88 patients, with resolution of obstruction in all treated patients. Tumor resection with primary anastomosis was possible in all patients. A temporary colostomy was performed in 40. Early complications did not occur. Late complications occurred in 11 patients. Stent migration was significantly higher in patients treated with partially-covered stents compared to the uncovered group (35% vs. 0%, P<0.001). Endoscopical re-intervention was required in 12% of patients. One patient with rectal cancer had an anastomotic dehiscence after surgery and he was successfully treated with endoscopic clipping. One year after surgery, all patients were alive and local recurrence have not been documented. This was a retrospective and uncontrolled study. Preliminary data from this large case series are encouraging, with a high rate of technical and clinical success and low rate of clinically relevant complications. Partially-covered SEMS should be avoided in order to reduce the risk of endoscopic re-intervention. Copyright © 2016. Published by Elsevier Masson SAS.

The use of interventional radiology has increased as the first-line management of complications after pancreatic resections. Patients in whom interventional radiology was performed were compared with those in whom interventional radiology was not performed as regards type of pancreatic resection, diagnosis, postoperative mortality and morbidity, postoperative pancreatic fistula postpancreatectomy haemorrhage, bile leakage, reoperation rate and length of hospital stay. Our aim was to evaluate the usefulness of interventional radiology in the treatment of complications after pancreatic resection. One hundred and eighty-two (62.8%) out of 290 patients experienced postoperative complications. Interventional radiology procedures were performed in 37 cases (20.3%): percutaneous drainage in 28, transhepatic biliary drainage in 8 and arterial embolisation in 3 cases. Technical success was obtained in all cases and clinical success in 75.7%. Reoperation was avoided in 86.5%. In patients with major complications, clinically relevant postoperative pancreatic fistula and bile leaks as well as those with late postpancreatectomy haemorrhage (P=0.030) and patients with postpancreatectomy haemorrhage grade C (P=0.029), interventional radiology was used (P<0.001, P<0.001 and P=0.009, respectively) significantly more frequently than in the remaining patients. The reoperation and mortality rates were similar in the two groups (P=0.885 and P=0.100, respectively) while patients treated with interventional radiology procedures had a significant longer length of hospital stay than those in the non-interventional radiology group (37.5 ± 23.4 vs. 18.7 ± 11.7 days; P<0.001). Interventional radiology procedures were useful, especially for patients with postoperative pancreatic fistulas and bile leaks in whom reoperation was very often avoided.

Endovascular aortic repair (EVAR) has been shown to be a valid and minimally invasive alternative to open abdominal aortic aneurysm repair. A major shortcoming for EVAR is the need to submit patients to regular follow-up to detect potential complications such as endoleak, limb occlusion, aneurysm expansion, aneurysm rupture, infection, structural failure, and migration. In this case report, we describe an uncommon case of late type III endoleak due to complete detachment of the stent-graft main body segment from its suprarenal uncovered fixation stent. It was treated with a custom-made Relay(®) NBS Plus (Bolton Medical, Barcelona, Spain) thoracic stent graft which also provided extra suprarenal fixation of the thoracic stent graft in the proximal neck. The postoperative period was uneventful and a computed tomography scan 1 year later revealed proper positioning of the stent graft and no signs of endoleak. The successful strategy chosen to correct this complication was at the same time original and infrequent, and also avoided potential complications related to open surgical repair and general anesthesia.

Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic vertical sleeve gastrectomy (LVSG), have been proposed as cost-effective strategies to manage obesity-related chronic disease. The objectives of this meta-analysis and systematic review were to analyze the "late postoperative complication rate (>30 days)" for these 2 procedures. Randomized controlled trials (RCTs) published between 2000 and 2015 comparing the late complication rates, that is, >30 days following LVSG and LRYGB in adult population (ie, 16 y and above) were selected from PubMed, Medline, Embase, Science Citation Index, Current Contents, and the Cochrane database. The outcome variables analyzed included mortality rate, major and minor complications, and interventions required for their management and readmission rates. Random effects model was used to calculate the effect size of both binary and continuous data. Heterogeneity among the outcome variables of these trials was determined by the Cochran Q statistic and I index. The meta-analysis was prepared in accordance with the Preferred Reporting of Systematic Reviews and Meta-Analyses guidelines. Six RCTs involving a total of 685 patients (LVSG, n=345; LRYGB, n=340) reported late major complications. A nonstatistical reduction in relative odds favoring the LVSG procedure was observed [odds ratio (OR), 0.64; 95% confidence interval (CI), 0.21-1.97; P=0.4]. Four RCTs representing 408 patients (LVSG, n=208; LRYGB, n=200) reported late minor complications. A nonstatistically significant reduction of 36% in relative odds favoring the LVSG procedure was observed (OR, 0.64; 95% CI, 0.28-1.47; P=0.3). A 37% relative reduction in odds was observed in favor of the LVSG for the need for additional interventions to manage late postoperative complications that did not reach statistical significance (OR, 0.63; 95% CI, 0.19-2.05; P=0.4). No study specifically reported readmissions required for the management of late complication. This meta-analysis and systematic review of RCTs shows that the development of late (major and minor) complications is similar between LVSG and LRYGB procedures, 6 months to 3 years postoperatively, and they do not lead to higher readmission rate or reoperation rate for either procedure. However longer-term surveillance is required to accurately describe the patterns of late complications in these patients.

Introduction Complicated grief is a prolonged grief disorder with elements of a stress response syndrome. We have previously proposed a biobehavioral model showing the pathway to complicated grief. Avoidance is a component that can be difficult to assess and pivotal to treatment. Therefore we developed an avoidance questionnaire to characterize avoidance among patients with CG. Methods We further explain our complicated grief model and provide results of a study of 128 participants in a treatment study of CG who completed a 15-item Grief-related Avoidance Questionnaire (GRAQ). Results of Avoidance Assessment Mean (SD) GRAQ score was 25. 0 ± 12.5 with a range of 0–60. Cronbach's alpha was 0.87 and test re-test correlation was 0.88. Correlation analyses showed good convergent and discriminant validity. Avoidance of reminders of the loss contributed to functional impairment after controlling for other symptoms of complicated grief. Discussion In this paper we extend our previously described attachment-based biobehavioral model of CG. We envision CG as a stress response syndrome that results from failure to integrate information about death of an attachment figure into an effectively functioning secure base schema and/or to effectively re-engage the exploratory system in a world without the deceased. Avoidance is a key element of the model. PMID:17629727

To report 45 cases of late traumatic flap complications after laser-assisted in situ keratomileusis (LASIK) and discuss the continually increasing number of cases in China. A multicentre retrospective survey of eye injuries was carried in 31 military hospitals from January 2006 to December 2011. Detailed information from the medical records of all 92 cases with a history of prior LASIK treatment were collected and summarised, with respect to visual acuity (VA), flap condition, treatment and final outcome. All Chinese publications relevant to late traumatic flap complications in Chinese patients were retrieved and summarised. 92 inpatients (92 eyes) underwent LASIK surgery; 45 of these had traumatic LASIK flap complications. Flap dislocation was the commonest and most needed surgical repair. VA after treatment was good and no statistically significant difference was observed when compared with the 47 cases without flap complications. 109 articles related to late traumatic flap complications after LASIK were retrieved from four Chinese document databases. There were 550 cases of late traumatic flap complications. From 2004, case reports became more common; 10 or more cases were reported in some case series. VA of most cases was good and there was no remarkable vision loss after treatment. Late traumatic flap complications after LASIK have become more frequent in China, although the prognosis of most cases is good. Published by the BMJ Publishing Group Limited.

Wound Healing Complications Following Guided Bone Regeneration for Ridge Augmentation: A Systematic Review and Meta-Analysis.

PubMed

Lim, Glendale; Lin, Guo-Hao; Monje, Alberto; Chan, Hsun-Liang; Wang, Hom-Lay

The rate of developing soft tissue complications that accompany guided bone regeneration (GBR) procedures varies widely, from 0% to 45%. The present review was conducted to investigate the rate for resorbable versus nonresorbable membranes and the timing of soft tissue complications. Electronic and manual literature searches were conducted by two independent reviewers using several databases, including MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and Cochrane Oral Health Group Trials Register, for articles published through July 2015, with no language restriction. Articles were included if they were clinical trials aimed at demonstrating the incidence of soft tissue complications following GBR procedures. Overall, 21 and 15 articles were included in the qualitative and quantitative synthesis, respectively. The weighted complication rate of the overall soft tissue complications, including membrane exposure, soft tissue dehiscence, and acute infection/abscess, into the calculation was 16.8% (95% CI = 10.6% to 25.4%). When considering the complication rate based on membrane type used, resorbable membrane was associated with a weighted complication rate of 18.3% (95% CI: 10.4% to 30.4%) and nonresorbable membrane with a rate of 17.6% (95% CI: 10.0% to 29.3%). Moreover, soft tissue lesions were reported as early as 1 week and as late as 6 months based on the included studies. Soft tissue complications after GBR are common (16.8%). Membrane type did not appear to significantly affect the complication rate, based on the limited number of data retrieved in this study. Technique sensitivity (ie, soft tissue management) may still be regarded as the main component to avoid soft tissue complications and, hence, to influence the success of bone regenerative therapy.

Patients with untreated gallbladder stones in situ are at high risk for late biliary complications after endoscopic papillary balloon dilation (EPBD) and bile duct stone extraction. Few data exist on the short-term and long-term results in these patients after the recurrence of bile duct stones and acute cholecystitis. The aim of this study was to evaluate the outcome of late biliary complications in patients with gallbladder stones in situ after EPBD. Fifty-six patients who developed late biliary complications, including bile duct stone recurrence (n=43) and acute cholecystitis (n=13), were managed at our institutions. We investigated the short-term and long-term outcomes after the management of late biliary complications. Complete removal of recurrent bile duct stones was achieved in 38 of 43 patients (88%) by repeated EPBD alone. Pancreatitis after repeated EPBD occurred in two patients (5%). After successful bile duct stone extraction by EPBD, none of the 16 patients who underwent cholecystectomy developed late biliary complications (mean follow-up period of 5.2 years), wheras re-recurrent bile duct stones occurred in three of the 21 patients (14%) with gallbladder stones left in situ (mean follow-up period of 4.4 years)(P=0.1148). Re-recurrent bile duct stones were successfully treated endoscopically. One of the eight patients who did not undergo cholecystectomy for acute cholecystitis had a recurrence of cholecystitis, which was managed conservatively. The long-term outcomes of late biliary complications are favorable when patients with concomitant gallbladder stones undergo cholecystectomy. Re-recurrent bile duct stones are considerable when gallbladder stones are left in situ, but should be treated endoscopically.

Patients with untreated gallbladder stones in situ are at high risk for late biliary complications after endoscopic papillary balloon dilation (EPBD) and bile duct stone extraction. Few data exist on the short-term and long-term results in these patients after the recurrence of bile duct stones and acute cholecystitis. The aim of this study was to evaluate the outcome of late biliary complications in patients with gallbladder stones in situ after EPBD. Fifty-six patients who developed late biliary complications, including bile duct stone recurrence (n=43) and acute cholecystitis (n=13), were managed at our institutions. We investigated the short-term and long-term outcomes after the management of late biliary complications. Complete removal of recurrent bile duct stones was achieved in 38 of 43 patients (88%) by repeated EPBD alone. Pancreatitis after repeated EPBD occurred in two patients (5%). After successful bile duct stone extraction by EPBD, none of the 16 patients who underwent cholecystectomy developed late biliary complications (mean follow-up period of 5.2 years), whereas re-recurrent bile duct stones occurred in three of the 21 patients (14%) with gallbladder stones left in situ (mean follow-up period of 4.4 years)(P=0.1148).

This study aimed to investigate the clinical outcomes of hematopoietic stem cell transplantation (HSCT) with total body irradiation-based myeloablative conditioning (TBI-MAC) in pediatric patients with acute lymphoblastic leukemia (ALL). We retrospectively examined patients with ALL who underwent HSCT with TBI-MAC from January 2000 to August 2016 at our institute. We enrolled 67 patients with a median follow-up period of 8 years. The 5-year event-free survival (EFS) and overall survival (OS) were 51.2% and 59.6%, respectively. At the first complete remission, HSCT exhibited significantly superior EFS and OS in our patients than that in patients with other diseases. We encountered 57.9% of patients with at least one late complication. Major late complications were short stature (26.3%) and hypogonadism (18.4%). While late complications were observed in several recipients of HSCT, late complication-related deaths occurred in three patients. The TBI-MAC regimen led to favorable clinical outcomes in pediatric patients with ALL who underwent HSCT. Thus, proper evaluation and management of late complications are mandatory.

Bioresorbable vascular scaffold (BRS) is an innovative device that provides structural support and drug release to prevent early recoil or restenosis, and then degrades into nontoxic compounds to avoid late complications related with metallic drug-eluting stents (DESs). BRS has several putative advantages. However, recent randomized trials and registry studies raised clinical concerns about the safety and efficacy of first generation BRS. In addition, the general guidance for the optimal practice with BRS has not been suggested due to limited long-term clinical data in Korea. To address the safety and efficacy of BRS, we reviewed the clinical evidence of BRS implantation, and suggested the appropriate criteria for patient and lesion selection, scaffold implantation technique, and management.

Glaucoma drainage implants (GDIs) are used to treat paediatric glaucoma resistant to conventional medical and surgical treatment, achieving good intraocular pressure (IOP) control and long-term success. Late endophthalmitis is a rare complication that may develop following GDI surgery. A 17-year-old male presented with acute endophthalmitis 2 years after Ahmed glaucoma valve implantation with pericardial patch graft for management of refractory glaucoma secondary to congenital ectropion uveae. The glaucoma tube was exposed due to erosion of the overlying conjunctiva with no visible pericardial graft. After control of active infection, he underwent tube revision surgery whereby the exposed tube was retained and repatched with a double-thickness pericardial patch graft. He did well following surgery with good control of IOP and restoration of vision. Conjunctival dehiscence with graft melting over the GDI tube presented a major risk factor for endophthalmitis. Prompt surgical revision of an exposed tube is highly recommended to avoid ocular morbidity.

We report on the development of traumatic ear lobe neuromas as a late complication of bilateral otoplasty performed 16 years previously. To our knowledge, this is the first and only described case of traumatic neuromas arising as a late complication of otoplasty in the English literature. Traumatic neuroma should be considered in the differential diagnosis of any nodular lesions that develop within the external ear in patients who have had otoplasty or any other form of external ear surgery or trauma.

Sulfur mustard (SM) was used during the Iraq-Iran war (1980-1988). Exposed veterans continue to suffer from its ocular, skin, and respiratory complications. We aimed to evaluate associations between early (at the time of acute exposure) and decades later skin manifestations in individuals with severe ophthalmologic complications secondary to sulfur mustard exposure. One hundred forty-nine veterans with severe ocular injuries were evaluated for acute and chronic skin complications. Logistic regression models were used to examine the associations between early and late skin manifestations. Late skin complaints were observed in nearly all survivors who had early skin lesions (131 out of 137; 95.62%). Seven out of 12 patients (58.33%) who did not have early skin lesions ultimately developed late skin complications. There was a significant relationship between the presence of lesions at the time of exposure and developing late skin complaints (two-sided Fisher's exact test, OR = 15.59, p < 0.001). There was an association between having at least one early skin lesion and occurrence of late skin complications. Survivors with blisters at the time of chemical exposure were more likely to complain of itching (95% CI: 3.63-25.97, p < 0.001), burning (OR = 11.16; 95% CI: 2.97-41.89, p < 0.001), pigmentation changes (OR = 10.17; 95% CI: 2.54-40.75, p = 0.001), dryness (OR = 6.71, 95% CI: 1.22-37.01, p = 0.03) or cherry angioma (OR = 2.59; 95% CI:1.21-5.55, p = 0.01) during the late phase. Using multivariate logistic models, early blisters remained significantly associated with latent skin complaints. Of note, the genitalia and great flexure areas were the most involved anatomical sites for both early and late skin lesions in SM exposed survivors. According to this study, the presence of blisters at the time of exposure to SM is the most important predictor of developing dermatologic complications decades later in patients with severe ophthalmologic complications from sulfur mustard exposure.

Using "Rebar" to Stabilize Rigid Chest Wall Reconstruction.

PubMed

Robinson, Lary A; Grubbs, Deanna M

2016-04-01

After major chest wall resection, reconstruction of the bony defect with a rigid prosthesis is mandatory to protect the underlying thoracic organs, and to prevent flail chest physiology. Although many methods have been described for chest wall reconstruction, a commonly used technique employs a composite Marlex (polypropylene) mesh with methyl-methacrylate cement sandwiched between two layers of mesh (MMS), which is tailored to the defect size and shape. In building construction, steel "rebar" is used to strengthen and reinforce masonry structures. To avoid the initial residual motion of the rigid prosthesis used to reconstruct very large defects, particularly the sternum, we devised a simple technique of adding one or more Steinmann steel pins as "rebar" to strengthen and immediately stabilize the prosthesis to the surrounding ribs and sternum. For the very large defects, particularly over the heart and great vessels, titanium mesh may also be readily added into the sandwich construction for increased strength and to prevent late prosthetic fractures. Short- and long-term results of this inexpensive modification of the MMS reconstruction technique are excellent. This modified MMS tailor-made prosthesis is only one-third the cost of the recently popular prosthetic titanium systems, takes much less operative time to create and implant, and avoids the well-described complications of late titanium bar fracture and erosion/infection as well as loosening of screws and/or titanium bars.

The late postoperative complications of choledochal cyst (CC) surgery are serious and include intrahepatic stones and biliary carcinoma; therefore, long-term follow-up is crucial. The subjects of this retrospective study were patients who underwent surgery for CC at Kagoshima University Hospital between April, 1984 and December, 2016. We analyzed the operative results, early and late postoperative complications, and postoperative follow-up rate. The study population comprised 110 CC patients (male/female: 33/77) with a median age at surgery of 4 years, 3 months (range 12 days-17 years). The patients underwent hepaticoduodenostomy (n = 1; 0.9%) or hepaticojejunostomy (n = 109; 99.1%). Late complications included intrahepatic bile duct (IHBD) dilatation (n = 1; 0.9%), IHBD stones (n = 3; 2.7%), and adhesive ileus (n = 4; 3.6%). There was no incidence of biliary carcinoma in this series. The rates of follow-up at our institute within 10 years of surgery and more than 20 years after surgery were 69.2% (18 of 26) and 14.5% (8 of 55), respectively. The follow-up rate after definitive surgery declined with time. Late complications were observed within 20 years, but biliary carcinoma was not observed. The follow-up rate should be increased to detect late complications. Moreover, patient education on long-term follow up is essential to prevent life-threatening events after definitive surgery for CC.

Blunt chest trauma can cause a wide variety of injuries including acute myocardial infarction (AMI). Although AMI due to coronary artery dissection caused by blunt chest trauma is very rare, it is associated with high morbidity and mortality. In the vast majority of patients with AMI, primary percutaneous coronary interventions (PCI) are performed to recanalize obstructed arteries, but PCI carries a substantial risk of hemorrhagic complications in the acute phase of trauma. We report a case of AMI due to right coronary artery (RCA) dissection caused by blunt chest trauma. The totally obstructed RCA was spontaneously recanalized with medical therapy. We could avoid primary PCI in the acute phase of blunt chest trauma because electrocardiogram showed early reperfusion signs. We performed an elective PCI in the subacute phase when the risk of bleeding subsided. Since the risk of severe hemorrhagic complications is greater in the acute phase of blunt chest trauma as compared with the late phase, deferring emergency PCI is reasonable if signs of recanalization are observed.

On categorizing gestational, birth, and neonatal complications following late pregnancy exposure to antidepressants: the prenatal antidepressant exposure syndrome.

PubMed

Gentile, Salvatore

2010-03-01

Late in utero exposure to antidepressants has been suspected of adversely impacting pregnancy outcome and compromising neonatal adaptation. Hence, the necessity exists to analyze published information on antidepressant use during late pregnancy to individuate potential recurrent patterns of iatrogenic complications. Computerized searches on MEDLINE, PsycINFO, ENBASE, and Cochrane Library through February 10, 2010 were performed for selecting literature information and investigating the safety of antidepressants when used during late pregnancy. Antidepressant treatment during late pregnancy may increase the rates of poor pregnancy outcome and neonatal withdrawal/toxic reactions. Because both gestational complications and neonatal adverse events acknowledge the same etiology, the author suggests including such iatrogenic events under the definition of prenatal antidepressant exposure syndrome, in order to increase clinicians' awareness about the spectrum of risks which may concern the mother-infant pair when antidepressant treatment is deemed indispensable during late pregnancy.

Many pediatric urologic disorders have sequelae that may affect patients well into adulthood. Despite adequate treatment, many patients are at risk for progressive urologic deterioration years after surgical reconstruction. While many pediatric urologists follow their patients years after surgery, screening for late complications is a shared responsibility with primary care providers. This article discusses potential late complications and appropriate follow-up for patients who have a history of ureteral reimplantation, pyeloplasty, hypospadias repair, posterior urethral valve ablation, and intestinal interposition.

The aim of this study is to describe the surgical outcomes of a single-institution experience in the surgical management of temporomandibular joint ankylosis, comparing interpositional arthroplasty with autogenous tissue and Matthews device arthroplasty. A retrospective analysis of temporomandibular joint ankylosis patients (n = 15), who underwent interpositional arthroplasty or Matthews device arthroplasty, was conducted. The surgical outcomes (preoperative, recent [4-6 weeks], intermediate [1 year], and late [3 years] postoperative maximal incisal opening, hospital stay, and complication, relapse, and reoperation rates) were compared. Significant (all p < 0.05) differences were recorded in temporomandibular joint ankylosis patients treated with interpositional arthroplasty with autogenous tissue (53.3%) versus Matthews device arthroplasty (46.7%) according to intermediate (25 ± 7 vs. 34 ± 5 mm) and late (19 ± 8 vs. 33 ± 5 mm) postoperative maximal incisal opening, intermediate (31% vs. 7%) and late (47% vs. 12%) postoperative relapse, and reoperation rate (38% vs. 0%). There was similarity (all p > 0.05) in preoperative (4.8 ± 2.9 vs. 4.9 ± 2.9 mm) and recent (35 ± 4 vs. 37 ± 4 mm) postoperative maximal incisal opening, hospital stay (3.5 ± 0.8 vs. 3.6 ± 0.8 days), and surgery-related complications (13% vs. 14%). Both surgical procedures evaluated were successful in initial management of temporomandibular joint ankylosis, but the Matthews device arthroplasty avoided postoperative relapse.

The arterial switch operation (ASO) for the transposition of the great arteries (TGA) with intramural coronary arteries has been performed using several techniques to avoid coronary events. We mainly performed ASO without coronary relocation by creating an aortopulmonary fenestration (Imai technique). Coronary circulation was rerouted by covering the aortopulmonary window and coronary orifices with a nonfacing sinus flap. Long-term results have not been reported. We describe our early and late results. Among 551 patients who underwent an ASO between 1985 and 2014, intramural coronary arteries were detected in 15 of them. Coronary arteries were managed using 2 techniques: the double-button method in 5 patients (with unroofing and trapdoor incision in 1 patient) and the Imai technique in 10 patients. There were 3 hospital deaths and 3 deaths after discharge, 5 of which showed coronary complications. Actual survival and freedom from coronary complications at 15 years were 70% and 67%, respectively, with the Imai technique and 40% and 20%, respectively, with the double-button method. Late coronary intervention was performed for a long intramural coronary artery stenosis in 1 patient who underwent the Imai technique. In the others, late aortography showed good patency of the aortopulmonary window and growth of the coronary pouch after the Imai technique. The Imai technique can be an option for coronary management in the presence of high-risk coronary anatomy, particularly distal intramural coronary artery stenosis and inseparable coronary arteries with an almost single orifice. Adequate neopulmonary artery augmentation must be performed to prevent right ventricular outflow stenosis. Copyright © 2016 The Society of Thoracic Surgeons. Published by Elsevier Inc.

Avoidance can be adaptive and facilitate the healing process of acute grief or it can be maladaptive and hinder this same process. Maladaptive cognitive or behavioral avoidance comprises the central feature of the condition of complicated grief. This article explores the concept of experiential avoidance as it applies to bereavement, including when it is adaptive when it is problematic. Adaptive avoidance is framed using an attachment theory perspective and incorporates insights from the dual process model (DPM). An approach to clinical management of experiential avoidance in the syndrome of complicated grief is included.

Stereotactic radiosurgery versus stereotactic radiotherapy for patients with vestibular schwannoma: a Leksell Gamma Knife Society 2000 debate.

PubMed

Linskey, M E

2000-12-01

By definition, the term "radiosurgery" refers to the delivery of a therapeutic radiation dose in a single fraction, not simply the use of stereotaxy. Multiple-fraction delivery is better termed "stereotactic radiotherapy." There are compelling radiobiological principles supporting the biological superiority of single-fraction radiation for achieving an optimal therapeutic response for the slowly proliferating, late-responding, tissue of a schwannoma. It is axiomatic that complication avoidance requires precise three-dimensional conformality between treatment and tumor volumes. This degree of conformality can only be achieved through complex multiisocenter planning. Alternative radiosurgery devices are generally limited to delivering one to four isocenters in a single treatment session. Although they can reproduce dose plans similar in conformality to early gamma knife dose plans by using a similar number of isocenters, they cannot reproduce the conformality of modern gamma knife plans based on magnetic resonance image-targeted localization and five to 30 isocenters. A disturbing trend is developing in which institutions without nongamma knife radiosurgery (GKS) centers are championing and/or shifting to hypofractionated stereotactic radiotherapy for vestibular schwannomas. This trend appears to be driven by a desire to reduce complication rates to compete with modern GKS results by using complex multiisocenter planning. Aggressive advertising and marketing from some of these centers even paradoxically suggests biological superiority of hypofractionation approaches over single-dose radiosurgery for vestibular schwannomas. At the same time these centers continue to use the term radiosurgery to describe their hypofractionated radiotherapy approach in an apparent effort to benefit from a GKS "halo effect." It must be reemphasized that as neurosurgeons our primary duty is to achieve permanent tumor control for our patients and not to eliminate complications at the expense of potential late recurrence. The answer to minimizing complications while maintaining maximum tumor control is improved conformality of radiosurgery dose planning and not resorting to homeopathic radiosurgery doses or hypofractionation radiotherapy schemes.

Late complications of thrombosis of the deep veins in the region between the popliteal vein termination and the confluence of the common iliac veins and inferior vena cava (suprapopliteal deep-vein thrombosis) are common and often unrecognized by those responsible for the initial management. Pharmacomechanical-assisted clearance of the thrombus at the time of first presentation provides the best opportunity for complete recovery with preservation of normal venous valve function and avoidance of recurrent deep-vein thrombosis and postthrombotic syndrome. Recent interventional radiology methods provide for rapid and complete thrombolysis even in some patients in whom thrombolysis was previously considered contraindicated.

Mediators of Outcome in Complicated Grief Treatment.

In this study, we examined the mechanisms of action of complicated grief treatment (CGT), an efficacious psychotherapy for complicated grief. We explored 3 putative mediators (guilt/self-blame related to the deceased, negative thoughts about the future, and avoidance) among treatment completers assigned to either CGT (n = 35) or interpersonal psychotherapy (n = 34) in a previously reported randomized controlled trial. Antidepressant use was examined as a moderator of mediation effects. A reduction in guilt/self-blame, negative thoughts about the future, and avoidance behavior each mediated the relationship between treatment group and complicated grief outcomes. Reduction in avoidance emerged as an independent mediator after controlling for all mediators. Reducing avoidance of situations and emotions connected to the loss seems to be a key mechanism of change in CGT. Revising counterfactual thinking around troubling aspects of the death may also play a role in facilitating effective adaptation to loss. © 2016 Wiley Periodicals, Inc.

From 1970 to 1979 open mitral commissurotomy (OMC) was indicated in 167 patients. In 22 cases a valvular prosthesis was inserted. In the 145 patients subjected to OMC there was one hospital and one late death. Four late systemic emboli (SE) in three patients. In 92% there was improvement in functional class. Poor post-op course in 8% due to mitral regurgitation (MR) added to mitral stenosis or iatrogenic MR subjected to annuloplasty with poor results and eventual mitral prosthetic implantation. Pre-op SE in 35%, intracavitary thrombosis (IT) in 23% and in 13% of cases without history of SE. IT found as often in atrium as in left auricular appendage. The vast majority of patients with IT were in atrial fibrillation (AF), this arrhythmia was present in 34% of the 145 cases. In hospitals where all cases of predominant mitral stenosis (MS) cannot be operated by OMC because of logistics, cases of MS with AF and surgical indication should be operated by OMC because of the correlations between AF and IT. Other indications for OMC are reviewed. The excellent post-op results with scarce late complications re-enforce the convenience of retaining the human mitral valve and avoiding valve replacement when repair is possible.

Cytomegalovirus (CMV) infection is one of the most important causes of morbidity and mortality in solid organ transplantation. It can present with hematuria, the most common urological complication in the early post-simultaneous pancreas-kidney (SPK) transplant period. In SPK transplantation, CMV infection usually occurs 1 month after transplantation. We report an instance of bladder-drained SPK transplant presenting with recurrent gross hematuria from CMV infected duodenal graft ulcers 15 years after preserved well-functioning grafts. Serum quantitative Polymerase Chain Reaction (qPCR) for CMV was negative. Postmortem duodenal graft staining for CMV was positive, and revealed the cause of the inciting ulcer. To our knowledge, our patient is the first reported case of very late onset invasive CMV disease causing duodenal graft ulcers 15 years after transplantation, as previously reported cases of posttransplant CMV disease occurred only as late as 18 months. In addition, the absence of correlation between CMV viremia and CMV-infected duodenal allograft in SPK transplant has not been reported. Our case demonstrates that CMV viral load is -unreliable to diagnose invasive CMV disease, and tissue biopsy should be obtained to avoid missed diagnosis causing high morbidity and mortality.

Late intrahepatic hematoma is a rare complication of the transjugular intrahepatic portosystemic shunt (TIPS) procedure. We describe a patient with Budd-Chiari syndrome (BCS), who presented with a large inrahepatic hematoma 13 days after TIPS. Review of the literature reveals only two previous cases, both occurring in patients with BCS and presenting after a similar time interval. This potentially serious complication appears to be specific for TIPS in BCS.

Ambispective cohort review. To examine the effects of early mobilization on patient outcomes, complications profile, and 30-day readmission rates. Prolonged immobilization after surgery can result in functional decline and an increased risk of hospital-associated complications. We conducted an ambispective study of 125 elderly patients (>65 years) undergoing elective spinal surgery for correction of adult degenerative scoliosis. We identified all unplanned readmissions within 30 days of discharge. Unplanned readmissions were defined to have occurred as a result of either a surgical or a nonsurgical complication. "Days of immobility" was defined as the number of days until a patient moved out of bed beyond a chair. Patients in the top and bottom quartiles were dichotomized into "early ambulators" and "late ambulators", respectively. Early ambulators were ambulatory within 24 hours of surgery, whereas late ambulators were ambulatory at a minimum of 48 hours after surgery. Complication rates, duration of hospital stay, and 30-day readmission rates were compared between early ambulators and late ambulators. Baseline characteristics were similar between both cohorts. Compared with patients with a longer duration of immobility (i.e., late ambulators), the prevalence of at least one perioperative complication was significantly lower in the early ambulators cohort (30% vs. 54%, P = 0.06). The length of inhospital stay was 34% shorter in the early ambulators cohort (5.33 days vs. 8.11 days, P = 0.01). Functional independence was superior in the early ambulators cohort, with the majority of patients discharged directly home after surgery compared with late ambulators (71.2% vs. 22.0%, P = 0.01). Early ambulation after surgery significantly reduces the incidence of perioperative complications, shortens duration of inhospital stay, and contributes to improved perioperative functional status in elderly patients. Even a delay of 24 hours to ambulation is associated with higher complication rates and inferior functional outcomes. 3.

To evaluate long-term clinical follow-up results of implanting subcutaneous port catheters (SPCs) on ipsilateral or contralateral with mastectomy side in patients with axillary lymph node dissection. A total of 73 patients composed of ipsilateral (34 catheters) and contralateral (39 catheters) groups, with SPCs were included. All patients had lumpectomy or modified radical mastectomy for breast cancer. Ipsilateral and contralateral groups had similar patient characteristics. Five late complications were seen in the ipsilateral group and 2 late complications in the contralateral group. No statistical significant difference was seen between two groups in regard to late complications. Four complications of the ipsilateral group were classified as major group C and 1 as major group D, while 1 complication of the contralateral group was classified as minor group B and 1 as major group C according to Society of Interventional Radiology (SIR) classification. No statistical significant difference was seen between complication rates of two groups in regard to SIR classification. SPC related complications do not differ in regard to ipsilateral or contralateral side selection on mastectomized patients with breast cancer and lymph node dissection. SPCs can be implanted on ipsilateral or contralateral sides of the operation in these patients.

We report here a case of acute lymphoblastic leukemia in remission presenting a late-onset bilateral hydronephrosis probably due to polyoma BK virus-induced proliferation of bladder endothelium on both ostii. The diagnosis was made virologically by BK virus Polymerase Chain Reaction (PCR) detection in the absence of any other bladder disease. Awareness of this late complication is necessary not only in patients after renal transplantation but also in patients after hematopoietic stem cell transplantation from matched unrelated donor.

Chlamydia trachomatis (CT), the most common bacterial sexually transmitted infection (STI) among young women, can result in serious sequelae. Although the course of infection is often asymptomatic, CT may cause pelvic inflammatory disease (PID), leading to severe complications, such as prolonged time to pregnancy, ectopic pregnancy, and tubal factor subfertility. The risk of and risk factors for complications following CT-infection have not been assessed in a long-term prospective cohort study, the preferred design to define infections and complications adequately. In the Netherlands Chlamydia Cohort Study (NECCST), a cohort of women of reproductive age with and without a history of CT-infection is followed over a minimum of ten years to investigate (CT-related) reproductive tract complications. This study is a follow-up of the Chlamydia Screening Implementation (CSI) study, executed between 2008 and 2011 in the Netherlands. For NECCST, female CSI participants who consented to be approached for follow-up studies (n = 14,685) are invited, and prospectively followed until 2022. Four data collection moments are foreseen every two consecutive years. Questionnaire data and blood samples for CT-Immunoglobulin G (IgG) measurement are obtained as well as host DNA to determine specific genetic biomarkers related to susceptibility and severity of infection. CT-history will be based on CSI test outcomes, self-reported infections and CT-IgG presence. Information on (time to) pregnancies and the potential long-term complications (i.e. PID, ectopic pregnancy and (tubal factor) subfertility), will be acquired by questionnaires. Reported subfertility will be verified in medical registers. Occurrence of these late complications and prolonged time to pregnancy, as a proxy for reduced fertility due to a previous CT-infection, or other risk factors, will be investigated using longitudinal statistical procedures. In the proposed study, the occurrence of late complications following CT-infection and its risk factors will be assessed. Ultimately, provided reliable risk factors and/or markers can be identified for such late complications. This will contribute to the development of a prognostic tool to estimate the risk of CT-related complications at an early time point, enabling targeted prevention and care towards women at risk for late complications.

A new technique using cyanoacrylate glue is suggested for closing the transparenchymal tract following metallic endoprosthesis placement in a patient with malignant biliary obstruction complicated by ascites. With this technique, complications related to bile reflux through the transparenchymal tract would be avoided after transhepatic endoprosthesis placement in patients who have ascites. This technique would also be useful for avoiding bleeding following transhepatic portal venous puncture.

The increased risk of brady- and tachy-arrhythmias in the congenital heart disease (CHD) population means that cardiac rhythm management devices are often required at an early age and expose patients to device-related complications. The present study drew upon four decades of experience at a tertiary adult congenital heart disease ACHD center and aimed to investigate the indication for cardiac implantable electronic devices (CIEDs) and predictors of late device-related complication requiring re-intervention. A retrospective review of pacing records of ACHD patients over forty years was carried out. The primary outcome measure was device related complication requiring re-intervention. Between 1970 and 2009, 238 structural CHD patients who received CIEDs with follow-up data were identified (structural group). As a comparator group, 98 patients with congenital conduction disease or long QT syndrome with a structurally normal heart (electrical group) were included in the study. During a mean follow-up of 9.6±8.5years, 72 (21%) patients (44 structural group, 28 electrical group) required ≥1 re-intervention due to device related complications. Multivariate analysis showed that age at the time of device implant was an independent predictor of late device-related complications (HR 0.77, 95% CI 0.60-0.98, p=0.04). Sub-analysis of the structural group showed that ACHD complexity (Bethesda guideline) was the only predictor late device-related complication in the structural group (HR 2.96, 95% CI: 1.67-5.26, p<0.01). Increasing age at device implant was inversely associated with late device-related complications. ACHD patients with complex anatomy are at increased risk of device-related complications at mid and long-term follow-up. Copyright © 2017 Elsevier B.V. All rights reserved.

The use of dermal fillers in minimally invasive facial aesthetic procedures has become increasingly popular of late, yet as the indications and the number of procedures performed increase, the number of complications is also likely to increase. Paying special attention to specific patient characteristics and to the technique used can do much to avoid these complications. Indeed, a well-trained physician can also minimize the impact of such problems when they do occur. A multidisciplinary group of experts in aesthetic treatments reviewed the main factors associated with the complications that arise when using dermal fillers. A search of English, French and Spanish language articles in PubMed was performed using the terms "complications" OR "soft filler complications" OR "injectable complications" AND "dermal fillers". An initial document was drafted that reflected the complications identified and recommendations as to how they should be handled. This document was then reviewed and modified by the expert panel, until a final text was agreed upon and validated. The panel addressed consensus recommendations about the preparation, the procedure and the post-procedural care. The panel considered it crucial to obtain an accurate medical history to prevent potential complications. An additional clinical assessment, including standardized photography, is also crucial to evaluate the outcomes and prevent potential complications. Furthermore, the state of the operating theatre, the patient's health status and the preparation of the skin are critical to prevent superficial soft tissue infections. Finally, selecting the appropriate technique, based on the physician's experience, as well as the characteristics of the patient and filler, helps to ensure successful outcomes and limits the complications. This consensus document provides key elements to help clinicians who are starting to use dermal fillers to employ standard procedures and to understand how best to prevent potential complications of the treatment.

To discuss the potentially significant complications associated with medial patellofemoral ligament (MPFL) reconstruction. Additionally, to review the most current and relevant literature with an emphasis on avoiding these potential complications. Multiple cadaveric studies have characterized the anatomy of the MPFL and the related morphologic abnormalities that contribute to recurrent lateral patellar instability. Such abnormalities include patella alta, excessive tibial tubercle to trochlear grove (TT-TG) distance, trochlear dysplasia, and malalignment. Recent studies have evaluated the clinical outcomes associated with the treatment of concomitant pathology in combination with MPFL reconstruction, which is critical in avoiding recurrent instability and complications. Although there remains a lack of consensus regarding various critical aspects of MPFL reconstruction, certain concepts remain imperative. Our preferred methods and rationales for surgical techniques are described. These include appropriate work up, a combination of procedures to address abnormal morphology, anatomical femoral insertion, safe and secure patellar fixation, appropriate graft length fixation, and thoughtful knee flexion during fixation.

Transarterial radioembolization consist in delivering small particles loaded with Yttrium90, a pure beta emitter, in order to treat primary and secondary liver tumors. This treatment needs precaution since inadequate delivery of these beads can lead to severe complications. Moreover, a precise radiation dosing is crucial to achieve a good clinical success and to avoid complications such as radioembolization-induced liver disease. This review describes all the precautions and highlights clinical and technical considerations that need to be taken to avoid complications.

Cosmetic Outcomes and Complications Reported by Patients Having Undergone Breast-Conserving Treatment

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

Hill-Kayser, Christine E., E-mail: hill@uphs.upenn.edu; Vachani, Carolyn; Hampshire, Margaret K.

Purpose: Over the past 30 years, much work in treatment of breast cancer has contributed to improvement of cosmetic and functional outcomes. The goal of breast-conservation treatment (BCT) is avoidance of mastectomy through use of lumpectomy and adjuvant radiation. Modern data demonstrate 'excellent' or 'good' cosmesis in >90% of patients treated with BCT. Methods and Materials: Patient-reported data were gathered via a convenience sample frame from breast cancer survivors using a publically available, free, Internet-based tool for creation of survivorship care plans. During use of the tool, breast cancer survivors are queried as to the cosmetic appearance of the treatedmore » breast, as well as perceived late effects. All data have been maintained anonymously with internal review board approval. Results: Three hundred fifty-four breast cancer survivors having undergone BCT and voluntarily using this tool were queried with regard to breast cosmesis and perceived late effects. Median diagnosis age was 48 years, and median current age 52 years. 'Excellent' cosmesis was reported by 27% (n = 88), 'Good' by 44% (n = 144), 'Fair' by 24% (n = 81), and 'Poor' by 5% (n = 18). Of the queries posted to survivors after BCT, late effects most commonly reported were cognitive changes (62%); sexual concerns (52%); changes in texture and color of irradiated skin (48%); chronic pain, numbness, or tingling (35%); and loss of flexibility in the irradiated area (30%). Survivors also described osteopenia/osteoporosis (35%), cardiopulmonary problems (12%), and lymphedema (19%). Conclusions: This anonymous tool uses a convenience sample frame to gather patient reported assessments of cosmesis and complications after breast cancer. Among the BCT population, cosmetic assessment by survivors appears less likely to be 'excellent' or 'good' than would be expected, with 30% of BCT survivors reporting 'fair' or 'poor' cosmesis. Patient reported incidence of chronic pain, as well as cognitive and sexual changes, also appears higher than expected.« less

The risk factors associated with death in complicated Stanford B acute aortic dissection (AAD) after thoracic endovascular aortic repair (TEVAR) are poorly understood. The aim of this study was to evaluate the early and late events and mortality of complicated Stanford B AAD associated with TEVAR. Sixty-two patients with complicated Stanford B AAD undergoing TEVAR were included in this study. Primary technical success of TEVAR was achieved in 61 (98.39%) cases. The early mortality rate was 9.68%. Procedural type I endoleak (p = 0.007, OR = 7.71, 95% CI: 1.75-34.01) and cardiac tamponade (p = 0.010, OR = 8.86, 95% CI: 1.70-4 6.14) were the significant predictors of early death in the multivariate model. The late mortality was 16.07%. Cox regression analysis revealed rupture of false lumen (p = 0.001, hazard ratio = 21.96, 95% CI: 3.02-82.12), postoperative myocardial infarction (p = 0.001, hazard ratio = 9.86, 95% CI: 2.12-39.64), and acute renal failure (p = 0.024, hazard ratio = 3.98, 95% CI: 1.26-12.11) to be independent risk factors of late mortality. Type I procedural endoleak and cardiac tamponade were the significant predictors of early death in patients of complicated Stanford B AAD undergoing TEVAR. Rupture of false lumen, postoperative myocardial infarction, and acute renal failure were the independent risk factors for late death after TEVAR. © 2014 Wiley Periodicals, Inc.

In patients bitten by North American rattlesnakes and treated with Crotalidae Polyvalent Immune Fab (Ovine) (FabAV), late hematologic abnormalities-persistent, recurrent, or late, new onset of hypofibrinogenemia, prolonged PT/INR, prolonged PTT, and/or thrombocytopenia beyond 48 h post-envenomation-are common, difficult to manage, and may result in morbidity and mortality are common, difficult to manage, and may result in morbidity and mortality. The optimal management of late hematologic abnormalities, particularly the use of further treatment with antivenom, has not been well defined. The current FabAV treatment regimen is to give antivenom as a bolus dose over a one-hour period. We describe our experience using a continuous intravenous infusion of FabAV for late hematologic effects and/or associated bleeding complications in rattlesnake envenomation. This is a retrospective, observational case series of patients envenomated by North American rattlesnakes at three medical centers managed with a continuous intravenous infusion of FabAV for late hematologic abnormalities and/or associated bleeding complications. Indications, dilution and infusion protocols, and duration of therapy were individualized. Five cases were identified between July 2010 and September 2011. All patients had profound late hematologic abnormalities and/or were associated with bleeding complications. Several patients had received repeat bolus infusions of FabAV, with or without human blood products, with either inadequate or only transient beneficial response. All patients were then managed with a continuous intravenous infusion of FabAV and all appeared to respond to the continuous intravenous infusion of FabAV, titrated to effect, with cessation of progression and, in most cases, improvement in hematologic abnormalities. Rates of infusion varied from 2 to 4 vials per 24 h (mean = 3.1 ± 0.4 vials/day). The termination of FabAV infusion was between day 6 and day 14 from the time of envenomation (mean = 10 ± 3 days), after which hematologic values were normalized or were normalizing in all patients and continued to do so. The use of FabAV as a continuous intravenous infusion, particularly after the acute phase of envenomation has passed, provides a continuous source of circulating antibodies to neutralize venom components reaching circulation from tissue stores and allows natural replenishment of hematologic factors such as platelets and/or fibrinogen. This method is an efficient use of FabAV, avoiding the wasteful excess of a bolus dose, may be more effective, eliminating the potential for destruction of hematologic factors when protective antivenom levels are lost between bolus FabAV doses, and appears to be safe. Further assessments of the stability and sterility of the product during infusion are needed. The need to continue hospitalization is the major drawback, but continued observation and inpatient care may be needed for other indications (e.g. bleeding) in this subset of patients. A continuous intravenous infusion of FabAV between 2 and 4 vials per day, titrated to effect, and continued for 6-14 days post-envenomation appeared to be associated with reversal of late hematologic effects of rattlesnake envenomation and, when combined with indicated human blood products, control of significant bleeding. Continuous intravenous infusion of FabAV may be safer, more efficacious, and more cost-effective than observation without FabAV treatment or as-needed bolus dosing in selected patients with late hematologic abnormalities.

[Role of long-term follow-up in management of late-onset post-hematopoietic stem cell transplant complications].

PubMed

Asano-Mori, Yuki

As the number of long-term survivors after allogeneic hematopoietic stem cell transplantation (HSCT) has increased owing to advances in transplantation and supportive care techniques, the health and welfare of these survivors have come into focus. However, they are still at risks for various complications, including chronic graft-versus-host disease, infectious diseases, and secondary cancers even in the late period, which can not only interfere with the patient's quality of life (QOL) but also lead to death. The importance of long-term follow-up (LTFU) and management have been recently recognized, and nationwide systems to promote LTFU care in patients receiving HSCT, such as medical fee revision, publication of a LTFU guideline unique to Japan, and preparation of patient pocketbook, is under consideration. The number of medical facilities at LTFU outpatient clinic is also increasing; therefore, an optimal comprehensive support system may be established sooner or later. However, self-management by patients is essential to overcome late complications as well as to improve QOL after HSCT. Healthcare professionals should collaborate and continue to make the greatest possible efforts to educate patients regarding the risks of late complications and their prevention.

Late-time cosmic acceleration: ABCD of dark energy and modified theories of gravity

We briefly review the problems and prospects of the standard lore of dark energy. We have shown that scalar fields, in principle, cannot address the cosmological constant problem. Indeed, a fundamental scalar field is faced with a similar problem dubbed naturalness. In order to keep the discussion pedagogical, aimed at a wider audience, we have avoided technical complications in several places and resorted to heuristic arguments based on physical perceptions. We presented underlying ideas of modified theories based upon chameleon mechanism and Vainshtein screening. We have given a lucid illustration of recently investigated ghost-free nonlinear massive gravity. Again, we have sacrificed rigor and confined to the basic ideas that led to the formulation of the theory. The review ends with a brief discussion on the difficulties of the theory applied to cosmology.

Neointimal hyperplasia and unfavorable remodeling have been demonstrated to be the major limitation to endovascular revascularization procedures. Intracoronary gamma radiation therapy has been shown to reduce the restenosis index. However, the late effects of these novel procedures are unknown. To evaluate the long-term effects on clinical and angiographic outcome of endovascular gamma radiation therapy following percutaneous transluminal coronary angioplasty (PTCA), serial angiography over a 2-year period was performed in 21 patients (22 lesions) who were treated with 192Ir in doses of 20-25 Gy after PTCA. Angiograms were analyzed using quantitative methods (QCA). The mean late loss between PTCA and 6 months was 0.20 +/- 0.59 and 0.13 +/- 0.84 between 6 months and 2 years. At 6 months, angiographic binary restenosis was present in six arteries (27.2%). At 2 years, binary restenosis was observed in six arteries (27.2%), including one patient who had developed restenosis and excluding one patient with spontaneous regression. Two early pseudoaneurysms and two late aneurysms were observed at 6 months, with little increase at 2 years. No other angiographic complication was observed. None of the patients or medical staff developed complications or illnesses that could be related to the effects of the radiation procedure. Gamma radiation therapy decreases late luminal loss, is safe and free of unexpected complications at 6 months follow-up, with no significant changes or late complications at 2-years' follow-up.

The purpose of this study was to review surgical outcomes after elective placement of peritoneal dialysis (PD) catheters in children with end-stage renal disease. Children with PD catheters placed between February 2002 and July 2014 were retrospectively reviewed. Outcomes were catheter life, late (>30days post-op) complications (catheter malfunction, catheter malposition, infection), and re-operation rates. Comparison groups included laparoscopic versus open placement, age<2, and weight<10kg. Univariate and multivariate analysis were performed. One hundred sixteen patients had 173 catheters placed (122 open, 51 laparoscopic) with an average patient age of 9.7±6.3years. Mean catheter life was similar in the laparoscopic and open groups (581±539days versus 574±487days, p=0.938). The late complication rate was higher for open procedures (57% versus 37%, p=0.013). Children age<2 or weight<10kg had higher re-operation rates (64% versus 42%, p=0.014 and 73% versus 40%, p=0.001, respectively). Adjusted for age and weight, open technique remained a risk factor for late complications (OR 2.44, 95% CI 1.20-4.95) but not re-operation. Laparoscopic placement appears to reduce the rate of late complications in children who require PD dialysis catheters. Children <2years age or <10kg remain at risk for complications regardless of technique. Copyright © 2016 Elsevier Inc. All rights reserved.

Thyroidectomy has been performed on an inpatient basis because of concerns regarding postoperative complications. These include cervical hematoma, bilateral recurrent laryngeal nerve injury and symptomatic hypocalcemia. We have reviewed the current available evidence and aimed to collate published data to generate incidence of the important complications. We performed a literature search of Medline, EMBASE and the Cochrane database of randomized trials. One hundred sixty papers were included. Twenty-one papers fulfilled inclusion criteria. Thirty thousand four hundred fifty-three day-case thyroid procedures were included. Ten papers were prospective and 11 retrospective. The incidences of complications were permanent vocal cord paralysis 7/30259 (0.02%), temporary hypocalcemia 129/4444 (2.9%), permanent hypocalcemia 405/29203 (1.39%), cervical hematoma 145/30288 (0.48%) and readmission rate 105/29609 (0.35%). Analysis of cervical hematoma data demonstrated that in only 3/14 cases the hematoma presented as an inpatient, and in the remaining 11/14, it occurred late, with a range of 2-9 days. There is a paucity of data relating to anesthetic techniques associated with ambulatory thyroidectomy. Cost comparison between outpatient and inpatient thyroidectomy was reported in three papers. Cost difference ranged from $676 to $2474 with a mean saving of $1301 with ambulatory thyroidectomy. There is a body of evidence that suggests that ambulatory thyroidectomy in the hands of experienced operating teams within an appropriate setting can be performed with acceptable risk profile. In most circumstances, this will be limited to hemithyroidectomies to reduce or avoid the potential for additional morbidity. We have found little evidence to support the use of one anesthetic technique over another. The rates of hospital admission and readmission related to anesthetic factors appear to be low and predominantly related to pain and postoperative nausea and vomiting. A balanced anesthetic technique incorporating appropriate analgesic and antiemetic regimens is essential to avoid unnecessary hospital admission/readmission.

Avoiding unfavourable outcomes in liposuction

PubMed Central

Khanna, Atul; Filobbos, George

2013-01-01

The origin of liposuction can be traced to an adverse event by Dujarrier in 1921 when he used a uterine curette to remove fat from the knees of a ballerina ending in an amputation secondary to damage of the femoral artery. The history of liposuction since then has been one of avoiding complications and optimising outcome. After this adverse event, liposuction was abandoned until the 1960's when Schrudde revived the practice using small stab incisions and sharp curettage with the secondary suction to aspirate the freed tissue. This technique was associated with a high incidence of complications especially seroma and skin necrosis. Illouz then replaced the curette with a blunt cannula connected to vacuum pump thus avoiding the complications of a sharp curette. Despite the presence of various techniques for liposuction, suction assisted liposuction (SAL) is still the standard technique of liposuction. This article aims to discuss literature regarding the various aspects of liposuction (SAL) and to highlight the salient points in the literature and in the senior author's experience in order to avoid unfavourable outcomes in liposuction. A literature review on avoiding complication is in liposuction including some of the seminal papers on liposuction. Liposuction is generally a safe procedure with reproducible outcome. Just like any surgical procedure it should be treated with the utmost care. Illouz published 10 commandments for liposuction in 1989 and we review these commandments to demonstrate how liposuction has evolved. PMID:24501475

Only about 8% of head and neck tumors affect the midface. This anatomical area is characterized by an enormous number of functionally important structures, and it is frequently only possible to achieve small resection margin distances. To avoid complications and unfavorable results, a dedicated preparation of both patient and surgeon is warranted. This review aims to provide encouragement for the postgraduate training of interested ENT specialists. Following the clinical course and based on recent literature, strategies to avoid complications of tumor surgery to the midface are given.

Evaluation of correlations between underlying disease and port complications. Retrospective analysis of a data set of 3160 port systems, which had been interventionally implanted over a period of 10 years. Of these, 1393 were included in the final evaluation. The 7 most common underlying diseases and port-induced complications were considered. Port-related thrombotic events, port pocket infections as well as the port-induced sepsis were evaluated and classified as either early or late complications. In 1393 ports, 131 experienced complications. Of these, 22.1 % (n = 29) were early and 79.6 % (n = 102) late complications. The overall incidence rate of late complications was 0.253/1000 observed days. It differed significantly between the underlying diseases (p < 0.001) and was significantly lower in colon carcinoma when compared with pancreatic (p = 0.049), gastric (p = 0.012) and bronchial carcinoma (p = 0.042). The incidence rate of the port sepsis between the underlying diseases also differed significantly (p =  0.006) and had the highest rate in gastric and bronchial carcinoma. The occurrence of a thrombotic event also showed a significant difference in the incidence rates between the underlying diseases (p = 0.045) and was highest in pancreatic and gastric carcinoma. There are significant differences in the incidences of complications between the underlying diseases. Knowledge about this can help to improve the port-care and to take specific preventive measures. © Georg Thieme Verlag KG Stuttgart · New York.

Intestinal Ostomy.

About 100 000 ostomy carriers are estimated to live in Germany today. The creation of an ostomy represents a major life event that can be associated with impaired quality of life. Optimal ostomy creation and proper ostomy care are crucially important determinants of the success of treatment and of the patients' quality of life. This article is based on pertinent publications retrieved by a selective search in PubMed, GoogleScholar, and Scopus, and on the authors' experience. Intestinal stomata can be created using either the small or the large bowel. More than 75% of all stomata are placed as part of the treatment of colorectal cancer. The incidence of stoma-related complications is reported to be 10-70%. Skin irritation, erosion, and ulceration are the most common early complications, with a combined incidence of 25-34%, while stoma prolapse is the most common late complication, with an incidence of 8-75%. Most early complications can be managed conservatively, while most late complications require surgical revision. In 19% of cases, an ostomy that was initially planned to be temporary becomes permanent. Inappropriate stoma location and inadequate ostomy care are the most common causes of early complications. Both surgical and patient-related factors influence late complications. Every step from the planning of a stoma to its postoperative care should be discussed with the patient in detail. Preoperative marking is essential for an optimal stoma site. Optimal patient management with the involvement of an ostomy nurse increases ostomy acceptance, reduces ostomy-related complications, and improves the quality of life of ostomy carriers.

Summary Aims Cardiac disease is emerging as an important contributor to maternal deaths in both lower-to-middle and higher-income countries. There has been a steady increase in the overall institutional maternal mortality rate in South Africa over the last decade. The objectives of this study were to determine the cardiovascular causes and contributing factors of maternal death in South Africa, and identify avoidable factors, and thus improve the quality of care provided. Methods Data collected via the South African National Confidential Enquiry into Maternal Deaths (NCCEMD) for the period 2011–2013 for cardiovascular disease (CVD) reported as the primary pathology was analysed. Only data for maternal deaths within 42 days post-delivery were recorded, as per statutory requirement. One hundred and sixty-nine cases were reported for this period, with 118 complete hospital case files available for assessment and data analysis. Results Peripartum cardiomyopathy (PPCM) (34%) and complications of rheumatic heart disease (RHD) (25.3%) were the most important causes of maternal death. Hypertensive disorders of pregnancy, HIV disease infection and anaemia were important contributing factors identified in women who died of peripartum cardiomyopathy. Mitral stenosis was the most important contributor to death in RHD cases. Of children born alive, 71.8% were born preterm and 64.5% had low birth weight. Seventy-eight per cent of patients received antenatal care, however only 33.7% had a specialist as an antenatal care provider. Avoidable factors contributing to death included delay in patients seeking help (41.5%), lack of expertise of medical staff managing the case (29.7%), delay in referral to the appropriate level of care (26.3%), and delay in appropriate action (36.4%). Conclusion The pattern of CVD contributing to maternal death in South Africa was dominated by PPCM and complications of RHD, which could, to a large extent, have been avoided. It is likely that there were many CVD deaths that were not reported, such as late maternal mortality (up to one year postpartum). Infrastructural changes, use of appropriate referral algorithm and training of primary, secondary and tertiary staff in CVD complicating pregnancy is likely to improve the outcome. The use of simple screening equipment and point-of-care testing for early-onset heart failure should be explored via research projects. PMID:26895406

Research in adults has shown that individual differences in harm avoidance (HA) modulate electrophysiological responses to affective stimuli. To determine whether HA in adolescents modulates affective information processing, we collected event-related potentials from 70 adolescents while they viewed 90 pictures from the Chinese affective picture system. Multiple regressions revealed that HA negatively predicted late positive potential (LPP) for positive pictures and positively predicted for negative pictures; however, HA did not correlate with LPP for neutral pictures. The results suggest that at the late evaluative stage, high-HA adolescents display attentional bias to negative pictures while low-HA adolescents display attentional bias to negative pictures. Moreover, these dissociable attentional patterns imply that individual differences in adolescents' HA modulate the late selective attention mechanism of affective information. Copyright © 2013.

Purpose To report the natural history and late complications of retinopathy of prematurity (ROP) in members of the baby boomer generation (1946–1964). Methods Retrospective observational series of 86 eyes from 47 adult ROP patients (aged 45 to 56 years) who did not receive treatment as infants. Posterior segment pathology, refractive status, lens status, and visual acuity were evaluated. Results Seventy-six eyes (88.4%) had posterior segment pathology due to ROP, including 22 (25.6%) with retinal detachments. The rates of myopia and cataract formation were 90.7% and 83.7%, respectively. Visual acuity was 20/200 or worse in 43 eyes (51.2%) and 20/60 or better in 35 (41.7%). Conclusions There are significant late complications of ROP underscoring the importance of lifelong follow-up. PMID:17057805

So far numerous post-transplant outcome predictors have been studied to decrease the loss of resources and grafts after organ transplantation. The role of education, as a predictor, in liver transplantation outcome has so far been studied in several articles. However, in most of the studies it was evaluated as a surrogate for socioeconomic status or other variants. The absolute impact of parents' education has rarely been studied. Adult patients are their own caregivers whereas pediatric liver transplantation recipients are mostly cared by their parents. To evaluate the effect of level of patients' education on the mortality and morbidity of pediatric liver transplant recipients. We studied a group of 91 children who had undergone liver transplantation in our center from March 21, 2012 to July 21, 2013. In this retrospective study, patients' medical charts and questionnaire were used to collect the necessary data. Post-transplantation mortality and complications were divided into two categories: Early (<6 months after liver transplantation), and late (≥6 months after the transplantation). Parents' educational level was also categorized into 5 groups. Multivariate analysis of all groups showed that paternal education is an independent predictor of the late post-transplantation complications (p=0.024). Educational level of children's mothers had no significant correlation with the late post-transplantation complications (p=0.45). Neither maternal (p=0.59) nor paternal (p=0.607) education had significant effect on the late post-transplantation mortality. Paternal educational level of liver transplanted children is associated with the late post-transplantation complications.

Purpose of this study was to determine the frequency of occurence of specific complications of monochorionic diamniotic twins born after 24 weeks of pregnancies and the effect of these complications on perinatal morbidity and mortality. Restrospective analysis. Dpt. of Obstetrics and Gynecology Masaryk University and University Hospital Brno. A retrospective analysis of 175 monochorionic diamniotic pregnancies (mo-bi), which were terminated after the 24th week of pregnancy at the Department of Obstetrics and Gynecology Masaryk University and University Hospital Brno between the years 2008-2013. The specific complications such as twin-to-twin syndrome (TTTs), twin anemia polycytemia sequens (TAPS), selective intrauterine growth restriction (sIUGR), twin-arterial revers perfusion sequence (TRAP), single intrauterine fetal death (IUFD), placental insufficiency with both twins were identified using prenatal ultrasound examinations, perinatal results and the result of pathological anatomical examinations. Perinatal morbidity, neonatal mortality and neurological development were evaluated. The numbers of late detections of specific complications were observed. Specific complications in our group were identified in 50 pregnancies (28.6%). TTTs was diagnosed most often, by 18 pregnancies (10.3%), next most frequent diagnosis were sIUGR (9.7%) and TAPS (3.4%). The placental insufficiency with both twins complicated 2.6% pregnancies. 10 children had abnormal neurological development. Pregnancies with late detection had the worst perinatal results. No acute TTTs during delivery was detected. Specific placental complication reached 29.7% in our file. The most frequent complication was TTTs (10.3%) and selective growth restriction (9.7%). Pregnancies with late diagnosis of these complications had the worst results. The prenatal care by monochorial biamnial pregnancies should be at specialized centres from the 16th week of pregnancy every two weeks.

Acute coronary syndromes without ST elevation are a major health and economic burden. Treatments such as glycoprotein IIb/IIIa antagonists like tirofiban reduce the risk of complications but the cost impact of these agents including cost offsets of avoiding complications are needed particularly in Europe. We used treatment patterns from the Prospective Registry of Acute Ischemic Syndromes in the UK, risk reductions derived from the PRISM-PLUS trial and cost estimates from the CHKS database to estimate the impact of tirofiban on PRAIS-UK patients with and without complications and subgroups at higher risk of complications. These subgroups (and proportions) were patients: (1) aged 60 or over with abnormal electrocardiograms (58%), (2) with ST depression or bundle branch block on admission (30%) and (3) with ST depression, bundle branch block or MI on admission (37%). Total cost of care in the UK at 6 months for the estimated 87339 acute coronary syndromes admissions annually was pound 213 million, which would increase by pound 33 million (15.7%) if tirofiban were given to all patients, avoiding 2422 complications at a mean cost per event avoided of pound 13388. Among the subgroups, the mean cost per event avoided ranges from pound 10856 for subgroup 1 to pound 5953 for subgroup 3. Treating the latter subgroup, would avoid 1977 events at a cost of pound 12 million (5.5%). The use of tirofiban in the UK to treat acute coronary syndromes patients without ST elevation provides an important therapeutic advantage at modest proportional increase in cost, particularly if targeted to higher risk subgroups as recommended in the European guidelines.

The American Diabetes Association and The European Association of The Study of Diabetes recommend people with Type 2 diabetes to do moderate to vigorous aerobic exercise for 150 min per week to avoid late diabetic complications. However, most people with diabetes do not follow the recommendation. Consumer health information technology (CHIT) might play a role in supporting behavior changes that promote health and well-being. A CHIT prototype of an online diabetes exercise system, which contained the newest research of low volume high-intensity interval training (HIT), was developed. To test the system we used a multi-method pilot evaluation that includes; interviews, paper prototyping, heuristic evaluation, and test with patients. The patients expressed satisfaction with HIT and appreciated that the system was web-based. The findings from this pilot study inspire to further development and evaluation of online CHIT systems to diabetics.

Diabetes mellitus presents a significant public health burden based on its increased morbidity, mortality, and economic cost. The high comorbidity and prevalence of concomitant diseases like hypertension and dyslipidemia in diabetic patients cause the high risk in developing secondary, cost intensive, and for the patient often disastrous late complications (nephropathy, retinopathy, neuropathy, and cardiovascular disease). Therefore, patients with diabetes mellitus need a global risk management that takes the various individual clinical problems into account. The current global standards of therapy in patients with diabetes mellitus are focused on the control of glycemia, blood pressure, and lipid levels, as well as aspirin therapy and avoiding of smoking. There are a number of guidelines and recommendations to manage these global issues. Our review will summarize current recommendations and consolidate therapeutic goals and treatments that are of vital importance in the global risk management in diabetic patients.

Summary Background Recent developments in hip arthroscopic techniques and technology have made it possible in many cases to avoid open surgical dislocation for treating a variety of pathology in the hip. Although early reports suggest favourable results’ using hip arthroscopy and it has been shown to be a relatively safe procedure, complications do exist and can sometimes lead to significant morbidity. Methods This is a review article. The aim of this manuscript is to present the most frequent and/or serious complications that could occur at or following hip arthroscopy and some guidelines to avoid these complications. Conclusion Most complications of hip arthroscopy are minor or transient but serious complications can occur as well. A lot of complication e.g. acetabular labral puncture go unreported. Appropriate education and training, precise and meticulous surgical technique with correct instrumentation, the right indication in the right patient and adherence to advice from mentors and experienced colleagues are all essential factors for a successful outcome.

Protective occlusion of the gastroduodenal artery (GDA) is required to avoid severe adverse effects and complications in radioembolization procedures. Because of the expandable features of HydroCoils, our goal was to occlude the GDA with only one HydroCoil to provide particle reflux protection. Twenty-three subjects with unresectable liver tumors, who were scheduled for protective occlusion of the GDA before radioembolization therapy, were included. The primary end point was to achieve a proximal occlusion of the GDA with only one detachable HydroCoil. Evaluated parameters were duration of deployment, and early (during the intervention) and late (7-21 days) occlusion rates of GDA. Secondarymore » end points included complete duration of the intervention, amount of contrast medium used, fluoroscopy rates, and adverse effects. In all cases, the GDA was successfully occluded with only one HydroCoil. The selected diameter/length range was 4/10 mm in 2 patients, 4/15 mm in 6 patients, and 4/20 mm in 15 patients. HydroCoils were implanted, on average, 3.75 mm from the origin of the GDA (range 1.5-6.8 mm), with an average deployment time of 2:47 (median 2:42, range 2:30-3:07) min. In 21 (91%) of 23 patients, a complete occlusion of the GDA was achieved during the first 30 min after the coil implantation; however, in all patients, a late occlusion of the GDA was present after 6 to 29 days. No clinical or technical complications were reported. We demonstrated that occlusion of the GDA with a single HydroCoil is a safe procedure and successfully prevents extrahepatic embolization before radioembolization.« less

Crossed renal ectopia is a rare pathology that is often asymptomatic. Intraoperative detection with a sigma complicated neoplasia is more infrequent and requires correct management to avoid a renal ureteral injury. To present a case report of a patient with a sigma complicated neoplasia and a crossed renal ectopia detected incidentally. We present the case of a 62-year-old man that was submitted for emergency surgery for a sigma perforated neoplasm, and who presented with a previously undiagnosed left-side CRE. During surgery there was a need to insert 2-double-J stents as a guide to both ureters and to avoid any injury to them. Crossed renal ectopia is a rare, often asymptomatic entity, the diagnosis of which is usually incidental. In our case, the detection of a concomitant complicated neoplasm, required identification of both ureters due the anatomic doubt of its localization and to avoid them being injured. In conclusion, upon finding a casual crossed renal ectopia during an emergency surgery of sigma, we recommend the identification of the ureters to facilitate its location and to avoid any injury to the ureters.

In order to evaluate the treatment results of radiotherapy it is important to estimate the degree of complications of the surrounding normal tissues as well as the frequency of tumor control. In this report, the cumulative incidence rate of the late radiation injuries of the normal tissues was calculated using the modified actuarial method (Cutler-Ederer's method) or Kaplan-Meier's method, which is usually applied to the calculation of the survival rate. By the use of this method of calculation, an accurate cumulative incidence rate over time can be easily obtained and applied to the statistical evaluation of the late radiation injuries.

PURPOSE To compare the late complications in the Ahmed Baerveldt Comparison Study during 5 years of follow-up. DESIGN Multicenter, prospective, randomized clinical trial. METHODS SETTINGS Sixteen international clinical centers. STUDY POPULATION Two hundred seventy six subjects aged 18 to 85 years with previous intraocular surgery or refractory glaucoma with intraocular pressure of > 18 mmHg. INTERVENTIONS Ahmed Glaucoma Valve FP7 or Baerveldt Glaucoma Implant BG 101-350. MAIN OUTCOME MEASURES Late postoperative complications (beyond 3 months), reoperations for complications, and decreased vision from complications. RESULTS Late complications developed in 56 subjects (46.8 ± 4.8 5 year cumulative % ± SE) in the Ahmed Glaucoma Valve group and 67 (56.3 ± 4.7 5 year cumulative % ± SE) in the Baerveldt Glaucoma Implant group (P = 0.082). The cumulative rates of serious complications were 15.9% and 24.7% in the Ahmed Glaucoma Valve and Baerveldt Glaucoma Implant groups respectively (P = 0.034) although this was largely driven by subjects who had tube occlusions in the two groups (0.8% in the Ahmed Glaucoma Valve group and 5.7% in the Baerveldt Glaucoma Implant group, P = 0.037). Both groups had a relatively high incidence of persistent diplopia (12%) and corneal edema (20%), although half of the corneal edema cases were likely due to pre-existing causes other than the aqueous shunt. The incidence of tube erosion was 1% and 3% in the Ahmed Glaucoma Valve and Baerveldt Glaucoma Implant groups, respectively (P = 0.04). CONCLUSIONS Long term rates of vision threatening complications and complications resulting in reoperation were higher in the Baerveldt Glaucoma Implant than the Ahmed Glaucoma Valve group over 5 years of follow-up.

2011-06-01

Purpose: There are few long-term studies of how the sequencing of postmastectomy radiotherapy (PMRT) and breast reconstruction (BR) affects the time to development of complications or patient satisfaction with BR. We therefore studied this issue. Methods and Materials: One hundred thirteen women who underwent BR at Beth Israel Deaconess Medical Center (Boston, MA) from 1999-2006 and also received PMRT were included. Complications requiring surgery were categorized as early (within 90 days of BR) or late. The median length of follow-up after BR was 46.5 months. Patients' general and esthetic satisfaction was assessed with a validated questionnaire. Results: Complications occurred amongmore » 32% of 57 women receiving PMRT before BR and 44% of 57 patients having BR before PMRT (p = 0.176). Early complications were more frequent in patients who had PMRT first (18%) than for those with BR first (11%) (p = 0.210); conversely, late complication rates in the two groups were 14% and 33%, respectively (p = 0.009). General satisfaction was comparable between the PMRT-first and BR-first groups (68% and 68%, respectively; p = 0.995); esthetic satisfaction rates were also similar (50% and 62%, respectively; p = 0.238). Conclusions: The sequencing of PMRT and BR did not have a substantial impact on the total risk of complications or patients' general and esthetic satisfaction. However, early complications tended to develop in patients having PMRT first, whereas patients having BR first had a higher risk of late complications. Additional study of the effects of sequencing of PMRT on particular types of reconstructions may help devise strategies for reducing these risks.« less

A Cost-effectiveness Analysis of Early vs Late Tracheostomy.

The timing of tracheostomy in critically ill patients requiring mechanical ventilation is controversial. An important consideration that is currently missing in the literature is an evaluation of the economic impact of an early tracheostomy strategy vs a late tracheostomy strategy. To evaluate the cost-effectiveness of the early tracheostomy strategy vs the late tracheostomy strategy. This economic analysis was performed using a decision tree model with a 90-day time horizon. The economic perspective was that of the US health care third-party payer. The primary outcome was the incremental cost per tracheostomy avoided. Probabilities were obtained from meta-analyses of randomized clinical trials. Costs were obtained from the published literature and the Healthcare Cost and Utilization Project database. A multivariate probabilistic sensitivity analysis was performed to account for uncertainty surrounding mean values used in the reference case. The reference case demonstrated that the cost of the late tracheostomy strategy was $45 943.81 for 0.36 of effectiveness. The cost of the early tracheostomy strategy was $31 979.12 for 0.19 of effectiveness. The incremental cost-effectiveness ratio for the late tracheostomy strategy compared with the early tracheostomy strategy was $82 145.24 per tracheostomy avoided. With a willingness-to-pay threshold of $50 000, the early tracheostomy strategy is cost-effective with 56% certainty. The adaptation of an early vs a late tracheostomy strategy depends on the priorities of the decision-maker. Up to a willingness-to-pay threshold of $80 000 per tracheostomy avoided, the early tracheostomy strategy has a higher probability of being the more cost-effective intervention.

Aortic Replacement with Sutureless Intraluminal Grafts

To avoid the anastomotic complications and long cross-clamp times associated with standard suture repair of aortic lesions, we have implanted sutureless intraluminal grafts in 122 patients since 1976. Forty-nine patients had disorders of the ascending aorta, aortic arch, or both: their operative mortality was 14% (7 patients), and the group's 5-year actuarial survival rate has been 64%. There have been no instances of graft dislodgment, graft infection, aortic bleeding, or pseudoaneurysm formation. Forty-two patients had disorders of the descending aorta and thoracoabdominal aorta: their early mortality was 10% (4 patients), and the group's 5-year actuarial survival rate has been 56%. There was 1 early instance of graft dislodgment, but no pseudoaneurysm formation, graft erosion, aortic bleeding, intravascular hemolysis, or permanent deficits in neurologic, renal, or vascular function. Thirty-one patients had the sutureless intraluminal graft implanted in the abdominal aortic position: their early mortality was 6% (2 patients), and the 5-year actuarial survival rate for this group has been 79%. There were no instances of renal failure, ischemic complication, postoperative paraplegia, pseudoaneurysm, or anastomotic true aneurysm. Our recent efforts have been directed toward developing an adjustable spool that can adapt to the widest aorta or the narrowest aortic arch vessel; but in the meanwhile, the present sutureless graft yields shorter cross-clamp times, fewer intraoperative complications, and both early and late results as satisfactory as those afforded by traditional methods of aortic repair.

To compare short-term clinical and radiological outcomes of anterior fusion-nonfusion hybrid surgery (cervical discectomy or corpectomy and fusion combine with cervical disc replacement) and posterior cervical laminoplasty for multilevel cervical spondylotic myelopathy (CSM). From January 2014 to December 2015, 105 patients who underwent anterior fusion-nonfusion hybrid surgery (AHS group, n=48) or posterior cervical laminoplasty (PCL group, n=57) for ≥3 disc levels CSM were included. Japanese Orthopedic Association (JOA) score, complications, and radiological results including cervical curvature and cervical range of motion (ROM) were compared between the two groups. The complications happened within 1 month after the surgery were recorded as early complication, otherwise would be late complications. Both groups gained significant JOA scores improvement (P<0.05). No significant different of JOA improvement was found between the two groups (P>0.05). The cervical curvature increased significantly in AHS group (P=0.024), whereas decreased significantly in PCL group (P=0.002). Cervical ROM of both two groups significantly decreased after the surgery (P<0.05). The preoperative and final follow-up cervical ROM, together with the total cervical ROM preservation rate were not significant different between the two groups (P>0.05). The AHS group had a significant higher early complication rate (22/48 vs. 15/57, P=0.037) and a lower late complication rate (9/48 vs. 21/57, P=0.041). Both anterior fusion-nonfusion hybrid surgery and cervical laminoplasty could gain satisfied neurological recovery. The anterior hybrid surgery may preserve cervical curvature with higher early complication rate and lower late complication rate than cervical laminoplasty. Copyright © 2018.

The lifesaving benefit of implantable cardioverter-defibrillators (ICDs) has been demonstrated. Their use has increased considerably in the past decade, but related complications have become a major concern. The purpose of this study was to assess the incidence and effect on outcomes of early (≤30 days) complications after ICD implantation for primary prevention in a large French population. We analyzed data from 5539 patients from the multicenter French DAI-PP (Défibrillateur Automatique Implantable-Prévention Primaire) registry (2002-2012) who had coronary artery disease or dilated cardiomyopathy and were implanted with an ICD for primary prevention. Overall, early complications occurred in 707 patients (13.5%), mainly related to lead dislodgment or hematoma (57%). Independent factors associated with occurrence of early complications were severe renal impairment (odds ratio [OR] 1.66, 95% confidence interval [CI] 1.17-2.37, P = .02), age ≥75 years (OR 1.01, 95% CI 1.00-1.02, P = .03), cardiac resynchronization therapy (OR 1.58, 95% CI 1.16-2.17, P = .01), and anticoagulant therapy (OR 1.28, 95% CI 1.02-1.61, P = .03). During a mean ± SD follow-up of 3.1 ± 2.3 years, 824 (15.8%) patients experienced ≥1 late complication (>30 days), and 782 (14.9%) patients died. After adjustment, early complications remained associated with occurrence of late complications (OR 2.15, 95% CI 1.73-2.66, P < .0001) and mortality (OR 1.70, 95% CI 1.34-2.17, P = .003). Early complications are common after ICD implantation for primary prevention, occurring in 1 in 7 patients, and are associated with an increased risk of late complications and overall mortality. Further studies are needed to investigate the underlying mechanisms of such associations. Copyright © 2016 Heart Rhythm Society. Published by Elsevier Inc. All rights reserved.

To estimate the incidence densities and cumulative incidence of diabetes-related complications in patients with type 1 diabetes for a maximum of 15-year follow-up. The estimations were further stratified by gender and age at diagnosis (ie, early onset: 0-12 years, late onset:≥13 years). A population-based retrospective longitudinal cohort study. Taiwan's National Health Insurance medical claims. 4007 patients newly diagnosed with type 1 diabetes were identified during 1999-2012. Acute complications included diabetic ketoacidosis (DKA) and hypoglycaemia. Chronic complications were cardiovascular diseases (CVD), retinopathy, neuropathy and nephropathy. The incidence density of retinopathy was greatest (97.74 per 1000 person-years), followed by those of nephropathy (31.36), neuropathy (23.93) and CVD (4.39). Among acute complications, the incidence density of DKA was greatest (121.11 per 1000 person-years). The cumulative incidences of acute complications after 12 years following diagnosis were estimated to be 52.1%, 36.1% and 4.1% for DKA, outpatient hypoglycaemia and hospitalised hypoglycaemia, respectively. For chronic complications, the cumulative incidence of retinopathy after 12 years following diagnosis was greatest (65.2%), followed by those of nephropathy (30.2%), neuropathy (23.7%) and CVD (4.1%). Females with late-onset diabetes were greatly affected by advanced retinopathy (ie, sight-threatening diabetic retinopathy) and hospitalised hypoglycaemia, whereas those with early-onset diabetes were more vulnerable to DKA. Chronic complications were more commonly seen in late-onset diabetes, whereas early-onset diabetes were most affected by acute complications. Ethnic Chinese patients with type 1 diabetes were greatly affected by DKA and retinopathy. The incidence of diabetes-related complications differed by age at diagnosis and sex. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Animal models have historically played a critical role in the exploration and characterization of disease pathophysiology and target identification and in the evaluation of novel therapeutic agents and treatments in vivo. Diabetes mellitus disease, commonly known as diabetes, is a group of metabolic disorders characterized by high blood glucose levels for a prolonged time. To avoid late complications of diabetes and related costs, primary prevention and early treatment are therefore necessary. Due to its chronic symptoms, new treatment strategies need to be developed, because of the limited effectiveness of the current therapies. We overviewed the pathophysiological features of diabetes in relation to its complications in type 1 and type 2 mice along with rat models, including Zucker Diabetic Fatty (ZDF) rats, BB rats, LEW 1AR1/-iddm rats, Goto-Kakizaki rats, chemically induced diabetic models, and Nonobese Diabetic mouse, and Akita mice model. The advantages and disadvantages that these models comprise were also addressed in this review. This paper briefly reviews the wide pathophysiological and molecular mechanisms associated with type 1 and type 2 diabetes, particularly focusing on the challenges associated with the evaluation and predictive validation of these models as ideal animal models for preclinical assessments and discovering new drugs and therapeutic agents for translational application in humans.

Coronary artery bypass grafting remains the standard treatment for patients with extensive coronary artery disease. Coronary surgery without use of cardiopulmonary bypass avoids the deleterious systemic inflammatory effects of the extracorporeal circuit. However there is an ongoing debate surrounding the clinical outcomes after on-pump versus off-pump coronary artery bypass (ONCAB versus OPCAB) surgery. The current review is based on evidence from randomized controlled trials (RCTs) and meta-analyses of randomized studies. It focuses on operative mortality, mid- and long-term survival, graft patency, completeness of revascularisation, neurologic and neurophysiologic outcomes, perioperative complications and outcomes in the high risk groups. Early and late survival rates for both OPCAB and ONCAB grafting are similar. Some studies suggest early poorer vein graft patency with off-pump when compared with on-pump, comparable midterm arterial conduit patency with no difference in long term venous and arterial graft patency. A recent, pooled analysis of randomised trials shows a reduction in stroke rates with use off-pump techniques. Furthermore, OPCAB grafting seems to reduce postoperative renal dysfunction, bleeding, transfusion requirement and respiratory complications while perioperative myocardial infarction rates are similar to ONCAB grafting. The high risk patient groups seem to benefit from off-pump coronary surgery. PMID:27942394

Significant research efforts have been made to improve the safety and efficacy of endovascular aneurysm repair (EVAR) in treating abdominal aortic aneurysm. This study aimed to examine the trends of perioperative outcomes of EVAR in the recent decade using a national validated database. Patients who underwent EVAR for intact abdominal aortic aneurysm between 2006 and 2015 were identified from the National Surgical Quality Improvement Program and divided into early (2006-2010) and late (2011-2015) periods. The primary outcome of the study was 30-day mortality. Secondary outcomes included operative time, length of hospital stay, and 30-day major complications (renal, cardiopulmonary, and wound infection). A total of 30,076 patients were identified, with 11,539 in the early period and 18,537 in the late period. The 30-day mortality was kept at a low level in both periods (1.2% vs 1.2%; P = .98), whereas both the mean operation time (155.5 ± 72.6 minutes vs 141.9 ± 73.7 minutes; P < .001) and length of hospital stay (3.24 ± 5.32 days vs 2.81 ± 4.30 days; P < .001) were decreased in the late period. The 30-day major complication rate was reduced by 19.6% (5.1% vs 4.1%; P < .0001), with decreased renal failure (1.4% vs 1.0%; P = .003), cardiopulmonary complications (2.2% vs 1.7%; P = .006), and wound complications (2.5% vs 1.8%; P < .001). All the decreasing trends of mortality, any 30-day complication, and each type of major complication were statistically significant. Being treated in the late period was independently associated with decreased 30-day major complications (odds ratio, 0.75; 95% confidence interval, 0.65-0.87; P < .001), and this effect was confirmed in the propensity score-matched cohort (odds ratio, 0.76; 95% confidence interval, 0.66-0.90; P < .001). Although the 30-day mortality remains similar, postoperative complications in EVAR have decreased significantly during the recent decade. The continuous improvement in endograft technology and surgical skills has resulted in decreased operative time, marked reduction in surgical complications, and shorter hospital length of stay after endovascular repair.

Several minimally invasive techniques for cardiac output monitoring such as the esophageal Doppler (ED) and arterial pulse pressure waveform analysis (APPWA) have been shown to improve surgical outcomes compared with conventional clinical assessment (CCA). To evaluate the cost-effectiveness of these techniques in high-risk abdominal surgery from the perspective of the French public health insurance fund. An analytical decision model was constructed to compare the cost-effectiveness of ED, APPWA, and CCA. Effectiveness data were defined from meta-analyses of randomized clinical trials. The clinical end points were avoidance of hospital mortality and avoidance of major complications. Hospital costs were estimated by the cost of corresponding diagnosis-related groups. Both goal-directed therapy strategies evaluated were more effective and less costly than CCA. Perioperative mortality and the rate of major complications were reduced by the use of ED and APPWA. Cost reduction was mainly due to the decrease in the rate of major complications. APPWA was dominant compared with ED in 71.6% and 27.6% and dominated in 23.8% and 20.8% of the cases when the end point considered was "major complications avoided" and "death avoided," respectively. Regarding cost per death avoided, APPWA was more likely to be cost-effective than ED in a wide range of willingness to pay. Cardiac output monitoring during high-risk abdominal surgery is cost-effective and is associated with a reduced rate of hospital mortality and major complications, whatever the device used. The two devices evaluated had negligible costs compared with the observed reduction in hospital costs. Our comparative studies suggest a larger effect with APPWA that needs to be confirmed by further studies. Copyright © 2015 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

The object of this study was to determine if early cranioplasty after decompressive craniectomy for elevated intracranial pressure in children reduces complications. Sixty-one consecutive cases involving pediatric patients who underwent autologous cranioplasty after decompressive craniectomy for raised intracranial pressure at a single academic children's hospital over 15 years were studied retrospectively. Sixty-one patients were divided into early (< 6 weeks; 28 patients) and late (≥ 6 weeks; 33 patients) cranioplasty cohorts. The cohorts were similar except for slightly lower age in the early (8.03 years) than the late (10.8 years) cranioplasty cohort (p < 0.05). Bone resorption after cranioplasty was significantly more common in the late (42%) than the early (14%) cranioplasty cohort (p < 0.05; OR 5.4). No other complication differed in incidence between the cohorts. After decompressive craniectomy for raised intracranial pressure in children, early (< 6 weeks) cranioplasty reduces the occurrence of reoperation for bone resorption, without altering the incidence of other complications.

To assess process-of-care indicators and outcomes in acute pyelonephritis (APN) in a general hospital emergency department, and compare them between uncomplicaed and complicated APN. Retrospective study of consecutive patients discharged with a diagnosis of APN. We studied health processof- care indicators (percentage admitted, avoidable hospitalization, appropriate initial antibiotic therapy, urine and blood cultures) and outcomes (hospital length of stay [LOS], discharge from the emergency department, revisits, mortality, yields of microbiological tests ordered). A total of 529 cases (59% of them complicated) were included. Patients with uncomplicated APN were significantly younger on average (mean, 39 years) than patients with complicated APN (56 years). Escherichia coli was the most common pathogen identified, although the percentage of E coli infection was lower in patients with complicated APN (78%) than in patients with uncomplicated APN (95%). The rates of admission and orders for urine and blood cultures were significantly higher and hospital LOS was longer in the group with complicated APN. Moreover, these patients had even longer stays if the initial antibiotic therapy was inappropriate. Significantly more patients with uncomplicated APN were discharged from the emergency department. Sixty-one percent of patients with uncomplicated APN were admitted; 9% of these cases were considered avoidable hospitalizations. Complicated APN is diagnosed more often in older patients, and E coli infection causes a smaller proportion of these cases. Hospital LOS is longer in complicated APN and more urine and blood cultures are ordered. Patients with uncomplicated APN are more often discharged from the emergency department, although the number of avoidable hospitalizations seems high based on the rate found in this study.

OBJECTIVE The authors evaluate the rate and discuss the pathomechanisms of very late (≥ 4-month) ischemic complications after flow-diverter stent (FDS) placement for intracranial aneurysms. METHODS The authors retrospectively reviewed the clinical data of the patients treated at Pitié-Salpêtrière Hospital between January 2010 and September 2014, who underwent FDS placement for intracranial aneurysm. The patients received dual-antiplatelet therapy (clopidogrel and aspirin) 5 days before and 3-6 months after the procedure and then aspirin alone for 6-9 months. An ischemic complication was defined as a sudden focal neurological deficit documented on diffusion-weighted images. RESULTS Eighty-six consecutive patients were included. Three (3.5%) patients treated with the Pipeline embolization device experienced a delayed acute ischemic stroke (2 cases of perforator/side-wall branch infarction and 1 case of thromboembolic stroke) with an average delay of 384 days (4 months, 20 months, and 13 months, respectively). The aneurysm locations were the left superior cerebellar artery, the right anterior choroid artery, and the left internal carotid artery (paraclinoid segment), respectively. The complications occurred after the patients had completed the antiaggregation protocol, except for Patient 1, who was receiving aspirin alone because of a spontaneous hematoma. At the acute phase, no in-stent thromboses were found on digital subtraction angiography. In Patient 2, the treated anterior choroid artery was occluded 20 months after the procedure. In Patient 3, a focal stenosis (approximately 40%) of the distal aspect of the FDS, probably caused by intimal hyperplasia, was seen. CONCLUSIONS Very late ischemic complications after FDS treatment were observed in 3.5% of the cases in the authors' series, some of which occurred as late as more than 1 year after placement.

cAMP/cAMP-dependent protein kinase (PKA) signaling pathway has been recently proposed to participate in both the late phase of long term potentiation in the hippocampus and in the late, protein synthesis-dependent phase of memory formation. Here we report that a late memory consolidation phase of an inhibitory avoidance learning is regulated by an hippocampal cAMP signaling pathway that is activated, at least in part, by D1/D5 receptors. Bilateral infusion of SKF 38393 (7.5 μg/side), a D1/D5 receptor agonist, into the CA1 region of the dorsal hippocampus, enhanced retention of a step-down inhibitory avoidance when given 3 or 6 h, but not immediately (0 h) or 9 h, after training. In contrast, full retrograde amnesia was obtained when SCH 23390 (0.5 μg/side), a D1/D5 receptor antagonist, was infused into the hippocampus 3 or 6 h after training. Intrahippocampal infusion of 8Br-cAMP (1.25 μg/side), or forskolin (0.5 μg/side), an activator of adenylyl cyclase, enhanced memory when given 3 or 6 h after training. KT5720 (0.5 μg/side), a specific inhibitor of PKA, hindered memory consolidation when given immediately or 3 or 6 h posttraining. Rats submitted to the avoidance task showed learning-specific increases in hippocampal 3H-SCH 23390 binding and in the endogenous levels of cAMP 3 and 6 h after training. In addition, PKA activity and P-CREB (phosphorylated form of cAMP responsive element binding protein) immunoreactivity increased in the hippocampus immediately and 3 and 6 h after training. Together, these findings suggest that the late phase of memory consolidation of an inhibitory avoidance is modulated cAMP/PKA signaling pathways in the hippocampus. PMID:9192688

Seizures after primary intracerebral hemorrhage (PICH) are significant and treatable complications, but the factors predicting immediate, early and late seizures are poorly known. We investigated characteristics and outcome with special reference to occurrence and timing of a first seizure among consecutive subjects with PICH. A population-based study was conducted in Northern Ostrobothnia, Finland, in 1993-2008 that included all patients with a first-ever primary ICH without any prior diagnosis of epilepsy. Immediate (<24h after admission), early (1-14 days) and late (>2 weeks) seizures were considered separately. Out of a total of 935 ICH patients, 51 had immediate, 21 early and 58 late seizures. The patients with seizures were significantly younger than the others and more often had a subcortical hematoma location (p<0.05). Lifestyle factors did not differ between the groups. The risk factors for immediate seizures in multivariable analysis were a low Glasgow coma scale score (GCS) on admission, subcortical location and age inversely (p<0.01). The only independent risk factor for early seizures was subcortical location (p<0.001), whereas subcortical location (p<0.001), age inversely (p<0.01) and hematoma evacuation (p<0.05) independently predicted late seizures. Immediate and early seizures predicted infectious complications (p<0.05). Patients with subcortical hematoma and of younger age are at risk for immediate seizures after primary ICH irrespective of hematoma size. Patients with immediate and early seizures more often had infectious complications. Surgery increases the risk of a late seizure after ICH. Copyright © 2014 Elsevier B.V. All rights reserved.

The optimal timing of cranioplasty after decompressive craniectomy for trauma is unknown. The aim of this study was to determine if early cranioplasty after decompressive craniectomy for trauma reduces complications. Consecutive cases of patients who underwent autologous cranioplasty after decompressive craniectomy for trauma at a single Level I Trauma Center were studied in a retrospective 10 year data review. Associations of categorical variables were compared using Chi-square test or Fisher's exact test. A total of 157 patients were divided into early (<12 weeks; 78 patients) and late (≥12 weeks; 79 patients) cranioplasty cohorts. Baseline characteristics were similar between the two cohorts. Cranioplasty operative time was significantly shorter in the early (102 minutes) than the late (125 minutes) cranioplasty cohort (P = 0.0482). Overall complication rate in both cohorts was 35%. Infection rates were lower in the early (7.7%) than the late (14%) cranioplasty cohort as was bone graft resorption (15% early, 19% late), hydrocephalus rate (7.7% early, 1.3% late), and postoperative hematoma incidence (3.9% early, 1.3% late). However, these differences were not statistically significant. Patients <18 years of age were at higher risk of bone graft resorption than patients ≥18 years of age (OR 3.32, 95% CI 1.25-8.81; P = 0.0162). After decompressive craniectomy for trauma, early (<12 weeks) cranioplasty does not alter the incidence of complication rates. In patients <18 years of age, early (<12 weeks) cranioplasty increases the risk of bone resorption. Delaying cranioplasty (≥12 weeks) results in longer operative times and may increase costs.

Musculoskeletal (MSK) intervention has proliferated in recent years among various subspecialties in medicine. Despite advancements in image guidance and percutaneous technique, the risk of complication has not been fully eliminated. Overall, complications in MSK interventions are rare, with bleeding and infection the most common encountered. Other complications are even rarer. This article reviews various complications unique to musculoskeletal interventions, assists the reader in understanding where pitfalls lie, and highlights ways to avoid them. PMID:26038623

Megavoltage x-radiation was used to treat orbital nasal, and paranasal cavity malignant neoplasia in 29 dogs. In each instance, the globe and adnexal tissues were within the treatment portals (entry and/or exit). Doses administered to tumors ranged from 3,680 to 5,000 cGy. Ocular reactions after irradiation were classified as mild in 5 of 29 cases (17.2%) and severe in 17 of 29 cases (58.6%). No ocular complications were noticed in 7 of 29 cases (24.1%). Complications frequently noticed included severe keratitis (41%), mild conjunctivitis (34%), severe conjunctivitis (28%), cataract (28%), and keratoconjunctivitis sicca (24%). Ocular complications that developed were not life threatening, but posed a threat to visual function and patient quality of life. Treatment for the complications included control of bacterial infection, reduction of tissue inflammation, and ocular surface protection when tear film deficiencies were noticed. Mild complications represented acute effects of irradiation, and typically resolved. Severe complications developed both acutely and as late irradiation effects. Those attributed to late irradiation effects were more vision threatening and altered the quality of life more than did the early effects.

Inherited Thrombophilia and Pregnancy Complications: Should We Test?

PubMed

Arachchillage, Deepa R J; Makris, Mike

2018-06-04

Recurrent miscarriages and pregnancy-related complications cause significant stress to couples looking for successful pregnancy outcome as well as to health care professionals. There is conflicting evidence with respect to the presence and the strength of associations between inherited thrombophilia and these complications. A complete thrombophilia screen is expensive, and no proven effective treatment for women with recurrent miscarriage and inherited thrombophilia is currently available. Based on the concept of microvascular thrombosis of the placenta, women with recurrent miscarriage and placenta-related complications frequently get treated with antithrombotic therapy. In this narrative review, the authors explore the evolving understanding and evidence of inherited thrombophilia in recurrent miscarriages and other pregnancy complications, and whether antithrombotic treatment would modify pregnancy outcome in women with inherited thrombophilia. Finally, they provide some personal recommendations based on available evidence for clinical practice. In summary, inherited thrombophilia testing is not required outside a clinical trial for women with recurrent pregnancy losses or late pregnancy complications. The presence of thrombophilia markers does not generally indicate additional therapy during pregnancy, even if a heritable thrombophilic defect is found in women with recurrent miscarriages or late pregnancy complications.

Port removal is usually a straightforward procedure delegated to trainees. However, some port removals are complicated by central venous catheter (CVC) fragmentation, a challenge for even experienced surgeons. This study aimed to determine the incidence of, and risk factors for, complicated port removal in children. A single-centre study assessed the outcome of removal for all paediatric ports inserted from 1996 to 2012. Data were recorded detailing patient, insertion, device and removal characteristics. Risk factors for complicated removals were scrutinised using Chi-square tests; p < 0.05 significant. Of 628 ports inserted from 1996 to 2012, 443 were subsequently removed at the same centre. 8/443 (1.8%) removals were complicated by CVC fragmentation, a median of 3.3 (2.4-3.9) years after insertion. Of complicated cases, 8/8 underwent formal neck dissection, 3/8 intravascular dissection, and 1/8 endovascular retrieval. 2/8 cases have retained intravascular CVC fragments. Risk factors for complication were CVC caliber <6Fr (p < 0.001) and use duration >2 years (p < 0.001). Greatest care and senior supervision should be ensured when removing ports with CVC caliber <6Fr and/or >2 years since insertion. However, complications also occur with larger CVCs or after shorter durations. Therefore, the key to avoiding complicated port removal may simply be: preparation, preparation, neck preparation.

In Japan, people using water from the well contaminated with high-level arsenic developed neurological, mostly cerebellar, symptoms, where diphenylarsinic acid (DPAA) was a major compound. Here, we investigated the adverse effects of developmental exposure to 20mg/l DPAA in drinking water (early period [0-6 weeks of age] and/or late period [7-12]) on behavior and cerebellar development in male rats. In the open field test at 6 weeks of age, early exposure to DPAA significantly increased exploratory behaviors. At 12 weeks of age, late exposure to DPAA similarly increased exploratory behavior independent of the early exposure although a 6-week recovery from DPAA could reverse that change. In the passive avoidance test at 6 weeks of age, early exposure to DPAA significantly decreased the avoidance performance. Even at 12 weeks of age, early exposure to DPAA significantly decreased the test performance, which was independent of the late exposure to DPAA. These results suggest that the DPAA-induced increase in exploratory behavior is transient, whereas the DPAA-induced impairment of passive avoidance is long lasting. At 6 weeks of age, early exposure to DPAA significantly reduced the concentration of cerebellar total glutathione. At 12 weeks of age, late, but not early, exposure to DPAA also significantly reduced the concentration of cerebellar glutathione, which might be a primary cause of oxidative stress. Early exposure to DPAA induced late-onset suppressed expression of NMDAR1 and PSD95 protein at 12 weeks of age, indicating impaired glutamatergic system in the cerebellum of rats developmentally exposed to DPAA.

Contemporary transcatheter aortic valve implantation (TAVI) devices and approach present opportunities to review historical practices initially informed by early treatment development and cardiac surgery. The avoidance of urinary catheterization in the older TAVI population is a strategy to minimize in-hospital complications. The purpose of the study was to explore elimination-related complications following the phased implementation of a default strategy of avoiding urinary catheterization in patients undergoing transfemoral (TF) TAVI. We conducted an observational study using a retrospective chart review of patients treated between 2011 and 2013 to identify patient characteristics, peri-procedure details, in-hospital outcomes and elimination-related complications in patients who did or did not receive a peri-procedure indwelling catheter. Descriptive analyses were used to report differences between the groups; we conducted a regression analysis to explore the relationship between the practice of urinary catheterization and total procedure time. Of the 408 patients who underwent TF TAVR, 188 (46.1%) received a peri-procedure indwelling urinary catheter and 220 (53.9%) did not. There was no difference in in-hospital mortality (2.2%), disabling stroke (0.5%), or other major cardiac adverse events. The avoidance of a urinary catheter resulted in significantly lower rates of urinary tract infection requiring a new antibiotic regimen (1.4% versus 6.1%, p = 0.014), haematuria documented by medicine or nursing (3.7% versus 17.6%, p = 0.001), and the need for continuous bladder irrigation (2.7% versus 0%, p = 0.027). The avoidance of a urinary catheter may contribute to improved outcomes in patients undergoing TAVI. The intervention should be further evaluated within the broader study of minimalist TAVI.

We tested the effect of the late (2006-2007) versus the early (2001-2005) study period on all outcomes using multivariable logistic regression models controlled for clustering among hospitals. Intraoperative and postoperative complications decreased from 7.0% to 0.8% (p < 0.001) and from 28.5% to 8.7% (p < 0.001), respectively. Transfusion rates decreased from 3.5% to 2.1% (p = 0.3). Hospital length of stay >2 d decreased from 56% to 15% (p < 0.001). In multivariable analyses, intraoperative (odds ratio [OR]: 0.41; p = 0.002) and postoperative (OR: 0.65; p = 0.007) complications were less frequent in the late versus the early study period. Late study period patients were less likely to stay >2 d than early study period patients (OR: 0.34; p > 0.001). Limitations of these findings include the lack of adjustment for several patient variables including disease characteristics, surgeon variables including surgeon caseload, and the restriction to in-hospital events. Our analyses demonstrate that in-hospital complication rates and length of stay after MIRP decreased over time. This implies that temporal differences specific to complication rates after MIRP must be considered when comparisons are made with other radical prostatectomy techniques.

Prospective, single-site, randomized, Food and Drug Administration-approved investigational device exemption clinical trials of 2 cervical arthroplasty (CA) devices. To evaluate complications with CA occurring more than 4 years after the surgical procedure in Food and Drug Administration clinical trials of the Bryan and Prestige LP arthroplasty devices. Reports of several randomized clinical studies have shown CA to be a safe and effective alternative to anterior cervical fusion in the treatment of degenerative cervical disc disorders. A majority include follow-up intervals of 4 years or less. Between 2002 and 2006, 94 patients were enrolled in Food and Drug Administration studies of the Bryan and Prestige LP cervical disc devices. Charts, imaging studies, and hospital records were reviewed for those who underwent arthroplasty and returned more than 4 years after their surgical procedure with neck-related pain or dysfunction. Excluding adjacent segment disease that occurred with a similar rate for patients who underwent fusion and arthroplasty, 5 patients, all treated with arthroplasty, returned for evaluation of neck and arm symptoms between 48 and 72 months after surgery. Four patients had peridevice vertebral body bone loss. One patient had posterior device migration and presented with myelopathy. Three required revision surgery and 2 were observed. Four patients maintained follow-up and reported stabilization or improvement in symptoms. Despite their similarities, CA and fusion are not equivalent procedures in this study in regard to very late complications. Similar to large joint arthroplasty, delayed device-related complications may occur with CA. These complications commenced well beyond the time frame for complications associated with more traditional cervical spine procedures. Both patients and surgeons should be aware of the potential for very late device-related complications occurring with CA and the need for revision surgery. 1.

Coagulation disorders and an immune-altered state are common among total artificial heart patients. In this context, we sought to evaluate the safety of percutaneous dilatational tracheostomy in cases of prolonged need for mechanical ventilatory support. We retrospectively analysed the charts of 11 total artificial heart patients who received percutaneous dilatational tracheostomy. We focused on early and late complications. We observed no major complications and no procedure-related deaths. Early minor complications included venous oozing (45.4%) and one case of local infection. Late complications, including subglottic stenosis, stomal infection or infections of the lower respiratory tract, were not observed. In conclusion, percutaneous dilatational tracheostomy in total artificial heart patients is safe. Considering the well-known benefits of early tracheotomy over prolonged translaryngeal intubation, we advocate early timing of therapy in cases of prolonged mechanical ventilation. © The Author 2015.

Management of appendicitis as an urgent rather than emergency procedure has become an increasingly common practice in children. Controversy remains as to whether this practice is associated with increased risk of complicated appendicitis and adverse events. To examine the association between time to appendectomy (TTA) and risk of complicated appendicitis and postoperative complications. In this retrospective cohort study using the Pediatric National Surgical Quality Improvement Program appendectomy pilot database, 2429 children younger than 18 years who underwent appendectomy within 24 hours of presentation at 23 children's hospitals from January 1, 2013, through December 31, 2014, were studied. The main exposure was TTA, defined as the time from emergency department presentation to appendectomy. Patients were further categorized into early and late TTA groups based on whether their TTA was shorter or longer than their hospital's median TTA. Exposures were defined in this manner to compare rates of complicated appendicitis within a time frame sensitive to each hospital's existing infrastructure and diagnostic practices. The primary outcome was complicated appendicitis documented at operation. The association between treatment delay and complicated appendicitis was examined across all hospitals by using TTA as a continuous variable and at the level of individual hospitals by using TTA as a categorical variable comparing outcomes between late and early TTA groups. Secondary outcomes included length of stay (LOS) and postoperative complications (incisional and organ space infections, percutaneous drainage procedures, unplanned reoperation, and hospital revisits). Of the 6767 patients who met the inclusion criteria, 2429 were included in the analysis (median age, 10 years; interquartile range, 8-13 years; 1467 [60.4%] male). Median hospital TTA was 7.4 hours (range, 5.0-19.2 hours), and 574 patients (23.6%) were diagnosed with complicated appendicitis (range, 5.2%-51.1% across hospitals). In multivariable analyses, increasing TTA was not associated with risk of complicated appendicitis (odds ratio per 1-hour increase in TTA, 0.99; 95% CI, 0.97-1.02). The odds ratios of complicated appendicitis for late vs early TTA across hospitals ranged from 0.39 to 9.63, and only 1 of the 23 hospitals had a statistically significant increase in their late TTA group (odds ratio, 9.63; 95% CI, 1.08-86.17; P = .03). Increasing TTA was associated with longer LOS (increase in mean LOS for each additional hour of TTA, 0.06 days; 95% CI, 0.03-0.08 days; P < .001) but was not associated with increased risk of any of the other secondary outcomes. Delay of appendectomy within 24 hours of presentation was not associated with increased risk of complicated appendicitis or adverse outcomes. These results support the premise that appendectomy can be safely performed as an urgent rather than emergency procedure.

2008-02-07

We aim to highlight the need for awareness of late complications of endovascular thoracic aortic stenting and the need for close follow-up of patients treated by this method. We report the first case in the English literature of an endovascular repair of a previously stented, ruptured chronic Stanford type B thoracic aortic dissection re-presenting with a type III endoleak of the original repair. Endovascular thoracic stenting is now a widely accepted technique for the treatment of thoracic aortic dissection and its complications. Long term follow up is necessary to ensure that late complications are identified and treated appropriately. In this case of type III endoleak, although technically challenging, endovascular repair was feasible and effective.

Post thyroidectomy suture granuloma: a cytological diagnosis.

Javalgi, Anita P; Arakeri, Surekha U

2013-04-01

There are known post thyroidectomized complications, a suture granuloma being less frequent, with its late complication mimicking recurrent thyroid cancer. A suture granuloma is a benign, granulomatous inflammatory reaction that occurs due to the use of non absorbable suture. It constitutes one of the late complications which altogether make up less than 2% of its incidence. A suture granuloma is similar to a foreign body reaction and it usually develops slowly as a painless, palpable asymptomatic mass over the years. It mimics a cancer recurrence or a lymph node metastasis. Here, we are reporting a case of a post thyroidectomy suture granuloma in a 46 years old lady who presented with a painless swelling in the lateral neck, with a past history of thyroidectomy 5 years back.

Supravalvular aortic stenosis as a late complication of transposition of the great arteries is very rare, and only a few cases have been reported. We describe the case of a 14-year-old girl who developed supravalvular aortic stenosis as a late complication of the arterial switch operation for transposition of the great arteries. The narrowed ascending aorta was replaced with a graft. The right pulmonary artery was transected to approach the ascending aorta which adhered severely to the main pulmonary trunk, and we obtained a good operative field. © The Author(s) 2015.

Guidelines now recommend endovenous thermal ablation over open treatment of saphenous incompetence, but flush saphenofemoral ligation and stripping remain relevant when appropriately applied and expertly executed. Complications are rare but could be severe, needing further surgical correction. We report a unique case of a late venous pseudoaneurysm of the great saphenous vein stump after flush saphenofemoral ligation and stripping, successfully treated with surgical sac excision. We highlight the importance of continuous follow-up for patients previously submitted to open venous surgery.

The purpose of this study was to determine the late complications in critically ill patients requiring percutaneous tracheostomy (PT) using the balloon dilation technique. A prospective, observational cohort study was carried out. Two medical-surgical intensive care units (ICU). All mechanically ventilated adult patients consecutively admitted to the ICU with an indication of tracheostomy. All patients underwent PT according to the Ciaglia Blue Dolphin ® method, with endoscopic guidance. Survivors were interviewed and evaluated by fiberoptic laryngotracheoscopy and tracheal computed tomography at least 6 months after decannulation. Intraoperative, postoperative and long-term complications and mortality (in-ICU, in-hospital) were recorded. A total of 114 patients were included. The most frequent perioperative complication was minor bleeding (n=20) and difficult cannula insertion (n=19). Two patients had severe perioperative complications (1.7%) (major bleeding and inability to complete de procedure in one case and false passage and desaturation in the other). All survivors (n=52) were evaluated 211±28 days after decannulation. None of the patients had symptoms. Fiberoptic laryngotracheoscopy and computed tomography showed severe tracheal stenosis (>50%) in 2patients (3.7%), both with a cannulation period of over 100 days. Percutaneous tracheostomy using the Ciaglia Blue Dolphin ® technique with an endoscopic guide is a safe procedure. Severe tracheal stenosis is a late complication which although infrequent, must be taken into account due to its lack of clinical expressiveness. Evaluation should be considered in those tracheostomized critical patients who have been cannulated for a long time. Copyright © 2017 Elsevier España, S.L.U. y SEMNIM. All rights reserved.

Pancreatic duct disruption (PDD) after acute pancreatitis can cause pancreatic collections in the early phase and biliary stenosis (BS) or gastric outlet obstruction (GOO) in the late phase. We aimed to document those late complications after moderate or severe acute pancreatitis. Between September 2010 and August 2014, 141 patients showed pancreatic collections on computed tomography. Percutaneous drainage was primarily performed for patients with signs or symptoms of uncontrolled pancreatic juice leakage. Pancreatic duct disruption was defined as persistent amylase-rich drain fluid or a pancreatic duct cut-off on imaging. Clinical course of the patients who developed BS or GOO was investigated. Among the 141 patients with collections, 33 patients showed PDD in the pancreatic head/neck area. Among them, 9 patients (27%) developed BS 65 days after onset and required stenting for 150 days, and 5 patients (15%) developed GOO 92 days after onset and required gastric decompression and jejunal tube feeding for 147 days (days shown in median). All 33 patients recovered successfully without requiring surgical intervention. Anatomic proximity of the bile duct or duodenum to the site of PDD and severe inflammation seemed to contribute to the late onset of BS or GOO. Conservative management successfully reversed these complications.

Complicated grief is a recently recognized condition that occurs in about 7% of bereaved people. People with this condition are caught up in rumination about the circumstances of the death, worry about its consequences, or excessive avoidance of reminders of the loss. Unable to comprehend the finality and consequences of the loss, they resort to excessive avoidance of reminders of the loss as they are tossed helplessly on waves of intense emotion. People with complicated grief need help, and clinicians need to know how to recognize the symptoms and how to provide help. This paper provides a framework to help clinicans understand bereavement, grief, and mourning. Evidence-based diagnostic criteria are provided to help clinicians recognize complicated grief, and differentiate it from depression as well as anxiety disorder. We provide an overview of risk factors and basic assumptions and principles that can guide treatment.

Pneumothorax is a collection of air in the pleural cavity. We conducted a retrospective study of patients with spontaneous pneumothorax in the Department of Pneumology at the Ibn Sina Hospital in Rabat (2009-2011) with the aim to determine the epidemiological, clinical, radiological, therapeutic and evolutionary manifestation of spontaneous pneumothorax. The study involved 138 patients: 128 men and 10 women (17-83 years), with an average age of 44.5 +/- 17.4 years and sex ratio of 12/8. 81.2% of patients were smokers. Clinical symptomatology was chest pain (92%), dyspnea (60%). Chest radiograph showed total unilateral (110 cases); partial (10 cases); localized (6 cases); bilateral (4 cases); right (51.4%) or left (45.7%) PNO (pneumothorax). During our study period we found that 70% of patients had spontaneous primitive pneumothorax and 30% had PNO secondary to Chronic obstructive pulmonary disease (COPD) (44%) and pulmonary tuberculosis (TB) (39%). Initial management included patients hospitalization, chest drainage (95%), needle exsufflation (1%), rest and O 2 (4%). It enables the lung to stick to the chest wall within 10 days in 63% of patients. Evolution was favorable in 89% of patients. Immediate complications included: subcutaneous emphysema (5 cases); infection (6 cases) and 3 deaths (cardiorespiratory arrest). Late complications included: recurrences in 11.6%; the first recurrence occurred in 13 cases (chest drainage in 11 cases and oxygen therapy in 2 cases) while the second recurrence occurred in 3 cases (surgery). This study shows the role of chest drainage and monitoring in the management of pneumothorax to avoid complications and especially to prevent recurrences, with a possible need to resort to surgery.

Local repair of stoma prolapse: Case report of an in vivo application of linear stapler devices.

Monette, Margaret M; Harney, Rodney T; Morris, Melanie S; Chu, Daniel I

2016-11-01

One of the most common late complications following stoma construction is prolapse. Although the majority of prolapse can be managed conservatively, surgical revision is required with incarceration/strangulation and in certain cases laparotomy and/or stoma reversal are not appropriate. This report will inform surgeons on safe and effective approaches to revising prolapsed stomas using local techniques. A 58 year old female with an obstructing rectal cancer previously received a diverting transverse loop colostomy. On completion of neoadjuvant treatment, re-staging found new lung metastases. She was scheduled for further chemotherapy but incarcerated a prolapsed segment of her loop colostomy. As there was no plan to resect her primary rectal tumor at the time, a local revision was preferred. Linear staplers were applied to the prolapsed stoma in step-wise fashion to locally revise the incarcerated prolapse. Post-operative recovery was satisfactory with no complications or recurrence of prolapse. We detail in step-wise fashion a technique using linear stapler devices that can be used to locally revise prolapsed stoma segments and therefore avoid a laparotomy. The procedure is technically easy to perform with satisfactory post-operative outcomes. We additionally review all previous reports of local repairs and show the evolution of local prolapse repair to the currently reported technique. This report offers surgeons an alternative, efficient and effective option for addressing the complications of stoma prolapse. While future studies are needed to assess long-term outcomes, in the short-term, our report confirms the safety and effectiveness of this local technique.

The use of a protective stoma represents an important issue in colorectal surgery. Although evidence suggests that loop ileostomy may be superior, the optimal method for temporary decompression of colorectal anastomosis still remains controversial. Aim of this study was to make an evidence-based proposal for a tailored approach to the use of diverting colostomy or ileostomy. A retrospective analysis of all patients subjected to creation and closure of a diverting loop colostomy or loop ileostomy between May 2007 and November 2014 in our institution was performed. Early and late complications, mortality and morbidity, time between formation and closure of the stoma in respect to adjuvant chemotherapy and the length of hospital stay were assessed and compared between the two groups. Outcomes of 167 patients (m=95; f=72) undergoing a loop colostomy (N.=130) or ileostomy (N.=37) were analyzed. The most frequent diagnosis was malignancy (64.1%), followed by abdominal emergency operations (18.6%) and complicated diverticular disease (17.4%). There was no mortality. Adjuvant chemotherapy (26.3%) resulted in delayed stoma reversal (P<0.001). Complications following construction of the stoma such as electrolyte disorder (P<0.001), renal insufficiency (P=0.048), and skin irritation (P=0.003) occurred significantly more often within the ileostomy group. Within the colostomy group, the rate of stoma prolapse (P=0.074) tended to be higher. Both methods have advantages and disadvantages. Loop transverse colostomy could be the preferred technique for older patients to avoid electrolyte disorder and renal insufficiency. Further prospective trials with documentation of electrolyte metabolism and quality of life should follow.

Open chest management with delayed sternal closure (DSC) is a valuable strategy in the management of patients with postcardiotomy hemodynamic instability or severe coagulopathy. The conventional extemporized material available for off-label sternal stenting however may limit its efficacy. We evaluated outcomes of patients with refractory severe postcardiotomy cardiogenic shock (SPCCS) treated with DSC using a novel temporary sternal spreader (NTSS) which allows myocardial recovery by progressive controlled approximation of the sternal edges. Seven patients (4 male, mean age 66.5 ± 5 years) with refractory SPCCS showing acute hemodynamic instability at sternal closure, were implanted with the NTSS, consisting of stainless-steel branches linked to 2 diverging plates of polyether-ether ketone, whose progressive opening/closing mechanism can be controlled from outside the chest with a rotating steel wire. The sternal wound was closed by an elastic membrane to achieve a sterile field. Swan-Ganz monitoring was employed, and clinical outcomes evaluated. The device was successfully implanted in all patients without device-related complications or failures. Progressive approximation of sternal edges, titrated on cardiac index values, was successfully completed allowing subsequent uneventful sternal closure in all. Mean time from SPCCS to sternal closure was 70 ± 21 hours. No patient developed infective complications or late hemodynamic instability after device removal and sternal closure. One patient (14%) died of multiorgan failure on postoperative day 9. Despite the limited number of patients enrolled, the NTSS proved safe and effective in allowing complete myocardial recovery after SPCCS, avoiding hemodynamic instability related to abrupt sternal closure, with no occurrence of infective complications.

Thrombophilia and Pregnancy Complications

Simcox, Louise E.; Ormesher, Laura; Tower, Clare; Greer, Ian A.

2015-01-01

There is a paucity of strong evidence associated with adverse pregnancy outcomes and thrombophilia in pregnancy. These problems include both early (recurrent miscarriage) and late placental vascular-mediated problems (fetal loss, pre-eclampsia, placental abruption and intra-uterine growth restriction). Due to poor quality case-control and cohort study designs, there is often an increase in the relative risk of these complications associated with thrombophilia, particularly recurrent early pregnancy loss, late fetal loss and pre-eclampsia, but the absolute risk remains very small. It appears that low-molecular weight heparin has other benefits on the placental vascular system besides its anticoagulant properties. Its use is in the context of antiphospholipid syndrome and recurrent pregnancy loss and also in women with implantation failure to improve live birth rates. There is currently no role for low-molecular weight heparin to prevent late placental-mediated complications in patients with inherited thrombophilia and this may be due to small patient numbers in the studies involved in summarising the evidence. There is potential for low-molecular weight heparin to improve pregnancy outcomes in women with prior severe vascular complications of pregnancy such as early-onset intra-uterine growth restriction and pre-eclampsia but further high quality randomised controlled trials are required to answer this question.

Malnutrition is associated with alcoholic liver disease (ALD) and related complications such as hepatic encephalopathy and increased rate of infections. Avoidance of prolonged fasting and overly restrictive diets is important to avoid poor nutrition. Adequate intake of calories, protein, and micronutrients via frequent small meals and evening supplements and/or enteral and parenteral nutrition when indicated has been associated with reduced mortality and morbidity in patients with ALD. Modification of protein/fat sources and composition in addition to probiotic supplementation are promising interventions for decreased progression of ALD and its complications.

Terror mismanagement: evidence that mortality salience exacerbates attentional bias in social anxiety.

Death anxiety is a basic fear underlying a range of psychological conditions, and has been found to increase avoidance in social anxiety. Given that attentional bias is a core feature of social anxiety, the aim of the present study was to examine the impact of mortality salience (MS) on attentional bias in social anxiety. Participants were 36 socially anxious and 37 non-socially anxious individuals, randomly allocated to a MS or control condition. An eye-tracking procedure assessed initial bias towards, and late-stage avoidance of, socially threatening facial expressions. As predicted, socially anxious participants in the MS condition demonstrated significantly more initial bias to social threat than non-socially anxious participants in the MS condition and socially anxious participants in the control condition. However, this effect was not found for late-stage avoidance of social threat. These findings suggest that reminders of death may heighten initial vigilance towards social threat.

The purpose of this retrospective study was to assess complications, voiding patterns, and quality of life in patients with an orthotopic bladder substitution, using an N-shaped ileal neobladder. Between May 1996 and December 2002, 58 patients (52 men and 6 women) underwent an orthotopic ileal neobladder reconstruction after radical cystectomy. The mean age was 47 for the female and 60 for the male patients. In all patients an N-shaped ileal pouch was constructed. This pouch has not yet been described in the literature before. All procedures were performed by the same surgeon (HVP) and the mean follow-up was 38 months. Complications were registered as early (occurring within 3 months) or late (occurring after 3 months), and as pouch-related and non-pouch-related. The patients took part in a pelvic floor re-education programme for as long as they were incontinent. All patients completed a retrospective Quality of Life questionnaire, based on the QLQ-C30 questionnaire, which was validated by the EORTC's Study Group on Quality of Life. In 38% of the patients, early complications occurred, whereas 48% had late complications. The most frequent early complications were diarrhea (24%) and pyelonephritis (9%). Diarrhea was again the most frequently mentioned non-pouch-related complication (19%). The most frequently observed pouch-related late complication was ileo-urethral stenosis. This occurred in five patients. All of these 5 patients were re-operated using a minimally invasive approach. Daytime continence was achieved in 95% of patients and nighttime continence in 66%. Hyper-continence with subsequent need for CISC was observed in 5 out of 6 women (83%) and 0 out of 52 men (0%). The retrospective QoL questionnaire learned that the impact of bladder removal and orthotopic bladder substitution has acceptable impact on patient's everyday life. Diarrhea was mentioned as being the most discomforting complication by most of the patients. We describe a modified orthotopic ileal neobladder: the ileal N-pouch. The functional results with this pouch are good. Complication rates and QoL are comparable with the larger series published by other authors, using different ileal neobladder reconstructions.

Gastric volvulus can be classified according to etiology as primary or secondary, according to anatomy as or mesenteroaxial, and according to onset as acute or chronic. Management of secondary gastric volvulus acute should always be surgery and the choice of surgical procedure for treatment is chosen according to etiology. Adherolysis and extraction of foreign bodies (suture, mesh, and gastric band) are important in those cases associated with previous abdominal surgery. Nissen fundoplication is a safe and effective procedure. Severe late complications of laparoscopic Nissen fundoplication are extremely rare occurrences. Among the reported complications is gastric volvulus. Presentation of two cases and review of literature. Two cases of acute gastric volvulus secondary to laparoscopic Nissen fundoplication presenting with epigastric pain and nonproductive retching and treated by laparoscopy are described. Symptoms upon presentation, incidence, diagnosis, treatment and predisposing factors to gastric volvulus postfundoplication are discussed. Gastric volvulus rarely occurs as a complication of Nissen fundoplication with an incidence similar to others of late complications. The described mechanisms that originate gastric volvulus postfundoplication are related to adhesions, foreign bodies as suture (polyester), gastrostomy tubes and mesh, gastropexy and internal gastric herniation through a "transfundoplication" window. A high index of suspicion is required in those patients presenting with acute symptoms of gastric obstruction in the first year following laparoscopic Nissen fundoplication. Laparoscopic approach is safe with or without gastropexy, always correcting the underlying mechanisms that cause gastric volvulus.

There is very limited information about the developmental outcome of the late preterm infant. The developing brain is vulnerable to injury during this very active and important stage of fetal brain development; therefore, it is important to carefully monitor the neurologic outcome of these infants. This article discusses gestational brain development and complications of late preterm birth that contribute to the overall risk of brain injury.

The aim of this paper is to identify the early and late implications of JPDD for biliary pathology, as well as for endoscopic therapy and classical surgery dealing mainly with lithiasis. This paper is based on a retrospective study comprising a number of 675 ERCP performed on 601 patients between 1997-2007, out of which 399 cases were followed by therapeutic measures. A total of 79 procedures were performed on 65 cases with JPDD. The main criteria were: gender, age, indications regarding the performance of ERCP+/-ES, complications that occurred while carrying out these procedures. In all the cases examined (601) the percentage of JPDD reported was of 10.81%. The rate of complications in the sphincterotomized patients without JPDD was 5.75% and the rate in the sphincterotomized patients with JPDD was 14.89%. In conclusion, the paper discusses the clinical and therapeutic implications of JPDD in biliary pathology. It has been found that JPDD is an important etiological cause for the late diseases occurring after cholelithiasis surgery. JPDD also leads to immediate therapeutic implications such as: difficult cannulation and high incidence of ERCP+/-ES complications.

Occurrence of congenital, cardiovascular, visceral, neurologic, and neuro-ophthalmologic complications in late yaws: a theme for future research.

Late lesions of yaws are thought to be limited to skin, bones and joints, without congenital, visceral, or central nervous system (CNS) involvement. However, the treponemes isolated from patients with yaws, endemic syphilis, and venereal syphilis are genetically identical subspecies of Treponema pallidum. The controversy surrounding distinctions between syphilis and yaws is presented in its historical context, and reports of congenital, visceral, and CNS complications of yaws are reviewed. Isolation of treponemes from aqueous humor, as well as CSF abnormalities in 24.9% of 902 patients with yaws, indicate the existence of CNS involvement. The high prevalence of tropical myeloneuropathies of unknown origin discovered in areas of previous treponemal endemicity, particularly in Jamaica and Colombia, may represent late complications of yaws. Careful analysis of the collected evidence indicates that potential sequelae of yaws include congenital, visceral, and tertiary CNS lesions identical to those of venereal syphilis. The current worldwide resurgence of endemic treponematoses provides an unparalleled opportunity to settle conclusively questions still unanswered regarding the natural history of these infections.

2013-01-01

There are known post thyroidectomized complications, a suture granuloma being less frequent, with its late complication mimicking recurrent thyroid cancer. A suture granuloma is a benign, granulomatous inflammatory reaction that occurs due to the use of non absorbable suture. It constitutes one of the late complications which altogether make up less than 2% of its incidence. A suture granuloma is similar to a foreign body reaction and it usually develops slowly as a painless, palpable asymptomatic mass over the years. It mimics a cancer recurrence or a lymph node metastasis. Here, we are reporting a case of a post thyroidectomy suture granuloma in a 46 years old lady who presented with a painless swelling in the lateral neck, with a past history of thyroidectomy 5 years back.

In Japan, people using water from the well contaminated with high-level arsenic developed neurological, mostly cerebellar, symptoms, where diphenylarsinic acid (DPAA) was a major compound. Here, we investigated the adverse effects of developmental exposure to 20mg/l DPAA in drinking water (early period [0–6 weeks of age] and/or late period [7–12]) on behavior and cerebellar development in male rats. In the open field test at 6 weeks of age, early exposure to DPAA significantly increased exploratory behaviors. At 12 weeks of age, late exposure to DPAA similarly increased exploratory behavior independent of the early exposure although a 6-week recovery from DPAA could reverse that change. In the passive avoidance test at 6 weeks of age, early exposure to DPAA significantly decreased the avoidance performance. Even at 12 weeks of age, early exposure to DPAA significantly decreased the test performance, which was independent of the late exposure to DPAA. These results suggest that the DPAA-induced increase in exploratory behavior is transient, whereas the DPAA-induced impairment of passive avoidance is long lasting. At 6 weeks of age, early exposure to DPAA significantly reduced the concentration of cerebellar total glutathione. At 12 weeks of age, late, but not early, exposure to DPAA also significantly reduced the concentration of cerebellar glutathione, which might be a primary cause of oxidative stress. Early exposure to DPAA induced late-onset suppressed expression of NMDAR1 and PSD95 protein at 12 weeks of age, indicating impaired glutamatergic system in the cerebellum of rats developmentally exposed to DPAA.

The optimal timing of cranioplasty after decompressive craniectomy for stroke is not known. Case series suggest that early cranioplasty is associated with higher rates of infection while delaying cranioplasty may be associated with higher rates of bone resorption. The authors examined whether the timing of cranioplasty after decompressive craniectomy for stroke affects postoperative complication rates. A retrospective cohort study was undertaken to evaluate complication rates in patients undergoing cranioplasty at early (within 10 weeks of craniectomy) or late (≥ 10 weeks) stages. Multivariate logistic regression analysis was used to determine characteristics that would predict complications in patients undergoing cranioplasty after decompressive craniectomy for stroke. While the overall complication rate was higher in the early cranioplasty cohort (22% vs 16% in the late cranioplasty cohort), the difference was not statistically significant (p = 0.5541). Patients in the early cranioplasty cohort had lower rates of postoperative hematoma but higher rates of infection. Presence of a CSF shunt was the only significant predictor of complications (OR 8.96, 95% CI 1.84-43.6). Complications rates for early cranioplasty (within 10 weeks of craniectomy) are similar to those encountered when cranioplasty is delayed, although the cohort size in this study was too small to state equivalence. Patients with a ventriculoperitoneal shunt are at higher risk for complications after cranioplasty.

The connection between Helicobacter pylori and complicated peptic ulcer disease in peptic ulcer bleeding (PUB) patients taking nonsteroidal anti-inflammatory drugs has not been established. In this study, we sought to determine whether delayed H. pylori eradication therapy in PUB patients increases complicated recurrent peptic ulcers. We identified inpatient PUB patients using the Taiwan National Health Insurance Research Database. We categorized patients into early (time lag ≤120 days after peptic ulcer diagnosis) and late H. pylori eradication therapy groups. The Cox proportional hazards model was used. The primary outcome was rehospitalization for patients with complicated recurrent peptic ulcers. Our data indicated that the late H. pylori eradication therapy group had a higher rate of complicated recurrent peptic ulcers (hazard ratio [HR], 1.52; p=0.006), with time lags of more than 120 days. However, our results indicated a similar risk of complicated recurrent peptic ulcers (HR, 1.20; p=0.275) in time lags of more than 1 year and (HR, 1.10; p=0.621) more than 2 years. H. pylori eradication within 120 days was associated with decreased complicated recurrent peptic ulcers in patients with PUB. We recommend that H. pylori eradication should be conducted within 120 days in patients with PUB.

Cytotoxic extravasation is a rare but potentially serious and painful complication of intravenous drug administration in oncology. Literature is anecdotal, and systematic clinical trials are scarce. The German working group for Supportive Care in Cancer (ASORS) has prepared an expert opinion for the diagnosis, prophylaxis and management of cytotoxic extravasation based on an interdisciplinary expert panel. A Pubmed search was conducted for diagnosis, risk factors, symptoms, prophylaxis, and treatment of extravasation by the respective responsible expert. A writing committee compiled the manuscript and proposed the level of recommendation. In a consensus meeting, 13 experts reviewed and discussed the current practice in diagnosis and management of cytotoxic extravasation. In a telephone voting among the experts, the level of recommendation by ASORS was determined. Every effort should be made to reduce the risk of extravasation. Staff training, patient education, usage of right materials and infusion techniques have been identified to be mandatory to minimalize the risk of extravasation. Extravasation must be diagnosed as soon as possible, and specific therapy including antidotes dependent on the extravasated drug should be initiated immediately. An extravasation emergency set should be available wherever intravenous cytotoxics are applied. Documentation and post-treatment follow-up are recommended. We have developed a literature- and expert-based consensus recommendation to avoid cytotoxic extravasation. It also provides practical management instructions which should help to avoid surgery and serious late effects. Copyright © 2013 S. Karger AG, Basel.

The genital herpes problem in pregnancy.

PubMed

Guerra, B; Puccetti, C; Cervi, F

2012-10-01

Genital herpes is a common sexually transmitted infection. In reproductive age it involves the additional risk of vertical transmission to the neonate. Rates of transmission are affected by the viral type and whether the infection around delivery is primary or recurrent. Neonatal herpes is a rare but very severe complication of genital herpes infection and is caused by contact with infected genital secretions at the time of labor. Maternal acquisition of herpes simplex virus (HSV) in the third trimester of pregnancy carries the highest risk of neonatal transmission. Prevention of neonatal herpes depends on preventing acquisition of genital HSV infection during late pregnancy and avoiding exposure of the infant to herpetic lesions during delivery. Uninfected woman should be counselled about the need of avoiding sexual contact during the third trimester. Elective caesarean section before the onset of labor is the choice mode of delivery for women with genital lesions or with prodromal symptoms near the term, even if it offers only a partial protection against neonatal infection. Antiviral suppressive therapy is used from 36 weeks of gestation until delivery in pregnant women with recurrences to prevent genital lesions at the time of labor so reducing the need of caesarean sections. Currently, routine maternal serologic screening is not yet recommended. Because most mothers of infants who acquire neonatal herpes lack histories of clinically evident genital herpes, researchers should focus on the recognition of asymptomatic primary genital HSV infections.

Recurrent massive hemorrhage from the ileum as a late complication of radiotherapy has not previously been documented. We describe two patients with a history of pelvic radiotherapy 18 months and 11 yr before, in whom the source of melena was localized to the small bowel preoperatively. Characteristic serosal appearances of ileal radiation injury were present at laparotomy and resection of the terminal ileum controlled the hemorrhage. Pathological study revealed no ulceration but multiple telangiectatic vessels in the tips of mucosal villi. This cause should be considered in patients with obscure gastrointestinal bleeding previously exposed to pelvic radiotherapy.

Late Corrective Arthrodesis in Nonplantigrade Diabetic Charcot Midfoot Disease Is Associated with High Complication and Reoperation Rates

2015-01-01

Introduction. Charcot arthropathy may lead to a loss of osteoligamentous foot architecture and consequently loss of the plantigrade alignment. In this series of patients a technique of internal corrective arthrodesis with maximum fixation strength was provided in order to lower complication rates. Materials/Methods. 21 feet with severe nonplantigrade diabetic Charcot deformity Eichenholtz stages II/III (Sanders/Frykberg II/III/IV) and reconstructive arthrodesis with medial and additional lateral column support were retrospectively enrolled. Follow-up averaged 4.0 years and included a clinical (AOFAS score/PSS), radiological, and complication analysis. Results. A mean of 2.4 complications/foot occurred, of which 1.5/foot had to be solved surgically. 76% of feet suffered from soft tissue complications; 43% suffered hardware-associated complications. Feet with only 2 out of 5 high risk criteria according to Pinzur showed significantly lower complication counts. Radiographs revealed a correct restoration of all foot axes postoperatively with superior fixation strength medially. Conclusion. Late corrective arthrodesis with medial and lateral column stabilization in the nonplantigrade stages of neuroosteoarthropathy can provide reasonable reconstruction of the foot alignment. Nonetheless, overall complication/reoperation rates were high. With separation into low/high risk criteria a helpful guide in treatment choice is provided. This trial is registered with German Clinical Trials Register (DRKS) under number DRKS00007537. PMID:26000309

Association Between Early Helicobacter pylori Eradication and a Lower Risk of Recurrent Complicated Peptic Ulcers in End-Stage Renal Disease Patients

Abstract End-stage renal disease (ESRD) patients exhibit an increased incidence of peptic ulcer disease. Helicobacter pylori plays a central role in the development of peptic ulcers. The effect of early H pylori eradication on the recurrence of complicated peptic ulcer disease in ESRD patients remains unclear. The aim of the present study was to explore whether early H pylori eradication therapy in ESRD patients can reduce the risk of recurrent complicated peptic ulcers. We conducted a population-based cohort study and recruited patients with ESRD who had developed peptic ulcers. We categorized patients into early (time lag ≦120 days after peptic ulcer diagnosis) and late H pylori eradication therapy groups. The Cox proportional hazards model was used. The endpoint was based on hospitalization for complicated recurrent peptic ulcers. The early and late H pylori eradication therapy groups consisted of 2406 and 1356 ESRD patients, respectively, in a time lag of 120 days. After adjusting for possible confounders, the early eradication group exhibited a lower rate of complicated recurrent peptic ulcer disease (hazard ratio [HR] = 0.76, 95% confidence interval [CI] = 0.64–0.91, P = 0.003) in a time lag of ≦120 days, but a similar rate of complicated recurrent peptic ulcer disease in time lags of ≦1 year (HR = 0.97, 95% CI 0.79–1.19, P = 0.758) and 2 years (HR = 1.11, 95% CI 0.86–1.44, P = 0.433) compared with the late eradication group. We recommend administering H pylori eradication within 120 days after peptic ulcer diagnosis to H pylori infected ESRD patients who have developed peptic ulcers. PMID:25569660

Although the American Society of Anesthesiologists (ASA) grade was established for statistical purposes, it is often used prognostically. However, older patients undergoing elective surgery are typically ASA III, which limits patient stratification. We look at the prognostic effect on early complications and survival of using ASA and self-reported physical fitness to stratify patients undergoing endovascular repair of abdominal aortic aneurysms. Data were extracted from a trial database. All patients were assigned a fitness level (A (fit) or B (unfit)) based on their self-reported ability to walk briskly for 1 km or climb two flights of stairs. Fitness was used to stratify ASA III patients, with fitter patients assigned ASA IIIA and less fit patients ASA IIIB. Outcomes assessed included survival, reinterventions, endoleak, all early and late complications and early operative complications. A combined ASA/fitness scale (II, IIIA, IIIB and IV) correlated with 1- and 3-year survival (1-year P = 0.001, 3-year P = 0.001) and early and late complications (P = 0.001 and P = 0.05). On its own, ASA predicted early complications (P = 0.0004) and survival (1-year P = 0.01, 3-year P = 0.01). Fitness alone was predictive for survival (1-year P = 0.001, 3-year P = 0.001) and late complications (P = 0.009). This study shows that even a superficial assessment of fitness is reflected in surgical outcomes, with fitter ASA III patients showing survival patterns similar to ASA II patients. Physicians should be alert to differences in fitness between patients in the ASA III group, despite similarities based on preexisting severe systemic disease. © 2017 Royal Australasian College of Surgeons.

Late veneer and late accretion to the terrestrial planets

It is generally accepted that silicate-metal ('rocky') planet formation relies on coagulation from a mixture of sub-Mars sized planetary embryos and (smaller) planetesimals that dynamically emerge from the evolving circum-solar disc in the first few million years of our Solar System. Once the planets have, for the most part, assembled after a giant impact phase, they continue to be bombarded by a multitude of planetesimals left over from accretion. Here we place limits on the mass and evolution of these planetesimals based on constraints from the highly siderophile element (HSE) budget of the Moon. Outcomes from a combination of N-body and Monte Carlo simulations of planet formation lead us to four key conclusions about the nature of this early epoch. First, matching the terrestrial to lunar HSE ratio requires either that the late veneer on Earth consisted of a single lunar-size impactor striking the Earth before 4.45 Ga, or that it originated from the impact that created the Moon. An added complication is that analysis of lunar samples indicates the Moon does not preserve convincing evidence for a late veneer like Earth. Second, the expected chondritic veneer component on Mars is 0.06 weight percent. Third, the flux of terrestrial impactors must have been low (≲10-6 M⊕ Myr-1) to avoid wholesale melting of Earth's crust after 4.4 Ga, and to simultaneously match the number of observed lunar basins. This conclusion leads to an Hadean eon which is more clement than assumed previously. Last, after the terrestrial planets had fully formed, the mass in remnant planetesimals was ∼10-3 M⊕, lower by at least an order of magnitude than most previous models suggest. Our dynamically and geochemically self-consistent scenario requires that future N-body simulations of rocky planet formation either directly incorporate collisional grinding or rely on pebble accretion.

Intralesional Injection of Collagenase Clostridium histolyticum May Increase the Risk of Late-Onset Penile Fracture.

The use of intralesional injection of collagenase Clostridium histolyticum (CCH) has become a valid treatment option in the management of Peyronie's disease (PD). Multiple studies have shown the drug's safety and efficacy. However, sparse literature exists on the utility of the injection protocol's 14-day "observation period," in which patients are instructed to abstain from all sexual activity. To summarize the contemporary literature and report on our series of patients treated with CCH in an effort to explore the effectiveness of the postinjection observation period. We retrospectively reviewed the clinical course of men treated with at least one CCH injection at our institution from April 2014 through February 2017. The main outcome measure for our cohort was complication rate (hematoma, fracture). Secondary outcomes included progression to corrective surgery. Of the 102 patients treated, 5 (4.9%) developed a corporal fracture. Four of these occurred outside the 14-day observation period. One fracture was managed conservatively and the rest underwent surgical exploration and repair. Twelve penile hematomas were reported; one of these patients was surgically explored because of suspicious magnetic resonance imaging findings. Seven patients (6.9%) progressed to corrective surgery. Penile hematoma and corporal fracture are serious complications that must be discussed with patients before initiation of intralesional CCH treatment. Little evidence exists to direct physicians on the proper management of post-CCH penile fractures; many caregivers and patients elect to treat these injuries conservatively and avoid surgical exploration. Further studies are warranted to generate discussion and reassessment regarding the safety and effectiveness of this 14-day observation period.

Hydrocephalus is a common complication of posterior fossa surgery, but its real incidence after microvascular decompression (MVD) for idiopathic trigeminal neuralgia (TN) still remains unclear. The aim of this study was to focus on the potential association between MVD and hydrocephalus as a surgery-related complication. All patients who underwent MVD procedure for idiopathic TN at our institute between 2009 and 2014 were reviewed to search for early or late postoperative hydrocephalus. There were 259 consecutive patients affected by idiopathic TN who underwent MVD procedure at our institution between 2009 and 2014 (113 men, 146 women; mean age 59 years, range 30-87 years; mean follow-up 40.92 months, range 8-48 months). Nine patients (3.47 %) developed communicating hydrocephalus after hospital discharge and underwent standard ventriculo-peritoneal shunt. No cases of acute hydrocephalus were noticed. Our study suggests that late communicating hydrocephalus may be an underrated potential long-term complication of MVD surgery.

Late Streptococcus bovis infection of total knee replacement complicated by infective endocarditis and associated with colonic ulcers

2013-01-01

Streptococcus bovis is rare cause of late infections after total knee replacement (TKR). This report presents a case of confirmed late septic arthritis following TKR caused by S bovis that was further complicated with infective endocarditis resulting in aortic valve insufficiency in an immunecompetent patient. As an association between S bovis and gastrointestinal malignancies is suggested, a workup for such malignancies was performed that revealed non-malignant ulcers in patient's ascending colon. The patient is currently recovering from his aortic valve replacement surgery and is scheduled to have annual colonoscopies. His knee joint has improved; however, he developed constant pain because of underlying chronic infection in the affected joint and has difficulties mobilising. Therefore, a revision TKR is considered but postponed until he fully recovers from his heart valve surgery. PMID:23744853

Ascending aorta wrapping is rarely recommended for the management of dilated aorta, because of late complications. The aim of the present study was to analyze the early and late outcomes of the aortic wrapping technique at the time of aortic valve replacement (AVR) for bicuspid aortic stenosis (BAS). Among patients who underwent primary AVR for BAS between 2002 and 2011, 79 who underwent ascending aortic wrapping (wrapping group) were compared with 144 patients who underwent AVR alone. The preoperative ascending aortic diameters were larger in the wrapping group (40.9±4.2 mm vs. 48.6±4.0 mm, P<0.001). Operative technique was to wrap the ascending aorta transversely with a semi-elliptically resected Dacron graft. The follow-up for the wrapping group was 76.5±35.5 (median 71.1) months. There were no early deaths. Early and late morbidity did not differ between groups. The 24 late deaths, including 10 cardiac-related deaths, occurred in the entire group; 3 sudden deaths occurred only in the AVR group. The 10-year overall survival in the wrapping group was higher than the AVR group (88.1±6.8% vs. 80.0±4.6%, P=0.048). No late aortic complications were detected. The aortic diameter was reduced from 49.5±4.1 mm to 45.3±5.0 mm after wrapping (P<0.001). The aortic wrapping technique may be an option for treating a moderately dilated ascending aorta in selected patients undergoing AVR for BAS. Longer follow-up, however, is necessary to verify later complications.

Diabetes prevention: perspectives and actions of one company.

2013-04-01

Diabetes, particularly type 2 diabetes mellitus (T2DM), has reached epidemic proportions in the U.S. and globally, highlighting the need for major improvements in treatment strategies for detecting, preventing, and slowing disease progression. Despite escalating treatment costs, diabetes care remains largely substandard, with hospitalizations for late-stage complications in particular placing a major burden on the healthcare system. Although considerable advances have been made in identifying the risk factors of diabetes and developing treatments, goals targeting prevention have remained elusive. Although there is currently no consensus regarding terminology among public health practitioners, the concept of prevention in terms of diabetes care runs the gamut from interventions used to avoid disease in individuals without risk factors (primordial prevention) to prevention of the consequences of established complications (quaternary prevention). Given the worldwide prevalence of diabetes, it is crucial to improve the quality of care for those diagnosed with overt diabetes, as well as those who have been identified as at risk for developing the disease. Earlier screening enables undiagnosed, asymptomatic individuals with diabetes to be identified sooner, managed more effectively, and where necessary, treated with the appropriate pharmacotherapeutic options in a timely manner. All stakeholders (including government, industry, professional, and patient groups) must partner in concert to address these vital issues so that treatment goals ultimately may be realized.

To evaluate and compare outcomes of Descemet's stripping endothelial keratoplasty (DSEK) with non-DSEK (nDSEK) in pseudophakic corneal oedema (PCE). The study was a prospective, non-consecutive, comparative, interventional case series. Twenty-six patients with PCE were randomised into two groups. Group 1 comprised of those cases that had undergone conventional DSEK, and group 2 consisted of those that had nDSEK for PCE between 2010 and 2012. The data on demographics and clinical characteristics were collected from all patients. Any intraoperative and early and late postoperative complications were also noted. The primary outcome measure was postoperative functional success. Graft survival and complications were analysed as secondary outcomes. The median best-corrected visual acuities at 6 months postoperatively in groups 1 and 2 were 0.18 (IQR 0.10-0.30) and 0.44 (IQR 0.18-0.51), respectively (p=0.11). Corneal oedema cleared in all patients. During the early postoperative period, a patient in group 2 had lenticule detachment managed by rebubbling. nDSEK has outcomes similar to DSEK in PCE with advantages of decreased surgical time and avoidance of inadvertent pull on the posterior stromal fibres that may occur during Descemet's stripping.

Owing to several therapeutic advancements, more patients with biliary atresia now survive into adulthood while retaining their native liver. However, the optimal strategy for long-term management of such patients remains unclear. Aiming to establish the current management strategies, we reviewed previous reports of long-term outcome of BA who underwent surgery at our institution as well as the relevant literature, focusing particularly on the treatment of late complications. Approximately 30-40% of long-term survivors of biliary atresia who retain their native liver exhibit late sequelae such as cholangitis and portal hypertension. Early and appropriate intervention with Kasai portoenterostomy is essential for ensuring long-term survival with good quality of life. In our hospital, the current standard for Kasai portoenterostomy involves dissecting the fibrous remnants along the porta hepatis, just on the level of the liver capsule. Cholangitis is an important late complication in biliary atresia, and the possibility of mechanical obstruction of the biliary drainage route or deformity of the intrahepatic bile ducts with or without gallstones should be thoroughly evaluated in patients with intractable cholangitis. Regarding portal hypertension, appropriate interventions such as endoscopic variceal treatment and partial splenic embolization are considered to provide good quality of life when hepatic function is preserved. Appropriate therapeutic management is strongly recommended in selected patients with late complications.

2017-06-27

Effective treatments for patients with advanced locally recurrent nasopharyngeal carcinoma (NPC) are limited. This investigation was to determine the potential benefits from re-irradiation by intensity-modulated radiotherapy (IMRT) on survival and the effects of severe late toxicities. A retrospective study was conducted in 245 patients diagnosed with locally recurrent T3-T4 NPC who had undergone re-irradiation with IMRT. Follow-up data was colletedand factors associated with survival and severe late toxicities were analyzed. The 5-year local-regional failure-free survival, distant failure-free survival and overall survival rates were 60.9%, 78.3% and 27.5%, respectively. The presence of severe late complications, recurrent T4 disease and gross tumor volume >30 cm3 were associated with poor survival. The incidences of mucosal necrosis, temporal lobe necrosis, cranial neuropathy and trismus were 22.0%, 14.6%, 27.0% and 14.6% respectively. Re-irradiation with IMRT is an effective choice in patients with locally recurrent T3-T4 NPC. However, the survival benefits can be partly offset by severe late complications and optimum treatments in these patients remain a challenge.

2012-07-01

The optimal timing of ostomy closure is a matter of debate. We performed a systematic review of outcomes of early ostomy closure (EC, within 8 weeks) and late ostomy closure (LC, after 8 weeks) in infants with necrotizing enterocolitis. PubMed, EMbase, Web-of-Science, and Cinahl were searched for studies that detailed time to ostomy closure, and time to full enteral nutrition (FEN) or complications after ostomy closure. Patients with Hirschsprung's disease or anorectal malformations were excluded. Analysis was performed using SPSS 17 and RevMan 5. Of 778 retrieved articles, 5 met the inclusion criteria. The median score for study quality was 9 [range 8-14 on a scale of 0 to 32 points (Downs and Black, J Epidemiol Community Health 52:377-384, 1998)]. One study described mean time to FEN: 19.1 days after EC (n = 13) versus 7.2 days after LC (n = 24; P = 0.027). Four studies reported complication rates after ostomy closure, complications occurred in 27% of the EC group versus 23% of the LC group. The combined odds ratio (LC vs. EC) was 1.1 [95% CI 0.5, 2.5]. Evidence that supports early or late closure is scarce and the published articles are of poor quality. There is no significant difference between EC versus LC in the complication rate. This systematic review supports neither early nor late ostomy closure.

Enhanced erythrocyte aggregation in type 2 diabetes with late complications.

PubMed

Demiroglu, H; Gürlek, A; Barişta, I

1999-01-01

We investigated whether erythrocyte aggregation (EA) is enhanced in type 2 diabetic patients who have developed microvascular or macrovascular complications. EA rates at high and low shear rates were analysed in 141 patients with type 2 diabetes who were further divided into 4 subgroups according to the status of diabetic complications and degree of metabolic control. Groups 1 (n = 43) and 2 (n = 23) consisted of well-controlled patients without and with clinically evident late complications, while groups 3 (n = 33) and 4 (n = 42) represented poorly controlled patients without and with these complications, respectively. 124 healthy subjects served as the control group. Mean EA rate was comparable between control subjects and group 1 both at high (2.05 +/- 0.03 vs. 2.14 +/- 0.07, respectively) and low (6.96 +/- 0.02 vs. 7.04 +/- 0.06, respectively) shear rates. Mean EA rate was also comparable between groups 2 and 4 at high (2.76 +/- 0.09 vs. 2.94 +/- 0.07, respectively) and low (8.18 +/- 0.13 vs. 8.41 +/- 0.1, respectively) shear rates. However, EA at both shear rates in groups 2 and 4 were significantly higher than control subjects, group 1 (p < 0.0001) and group 3 (high shear rate EA: 2.76 +/- 0.09 and low shear rate EA: 7.48 +/- 0.07 (p < 0.01). In group 3, EA rates were significantly higher than control subjects and group 1 (p < 0.05) at both shear rates. No significant correlation was found between EA at high and low shear rates and fibrinogen levels in diabetic subgroups and control subjects. The data suggest that patients with type 2 diabetes who had developed clinically evident late complications have enhanced EA regardless of the degree of metabolic control. Whether enhanced EA is a primary phenomenon contributing to the development of these complications or it occurs secondary to their development remains to be clarified.

Operative treatment of intra-articular calcaneal fractures with calcaneal plates and its complications

PubMed Central

Rak, Vaclav; Ira, Daniel; Masek, Michal

2009-01-01

Background: In a retrospective study we analysed intra-articular calcaneal fracture treatment by comparing results and complications related to fracture stabilization with nonlocking calcaneal plates and locking compression plates. Materials and Methods: We performed 76 osteosynthesis (67 patients) of intra-articular calcaneal fractures using the standard extended lateral approach from February 2004 to October 2007. Forty-two operations using nonlocking calcaneal plates (group A) were performed during the first three years, and 34 calcaneal fractures were stabilized using locking compression plates (group B) in 2007. In the Sanders type IV fractures, reconstruction of the calcaneal shape was attempted. Depending on the type of late complication, we performed subtalar arthroscopy in six cases, arthroscopically assisted subtalar distraction bone block arthrodesis in six cases, and plate removal with lateral-wall decompression in five cases. The patients were evaluated by the AOFAS Ankle-Hindfoot Scale. Results: Wound healing complications were 7/42 (17%) in group A and 1/34 (3%) in group B. No patient had deep osseous infection or foot rebound compartment syndrome. Preoperative size of Böhler's angle correlated with postoperative clinical results in both groups. There were no late complications necessitating corrective procedure or arthroscopy until December 2008 in Group B. All late complications ccurred in Group A. The overall results according to the AOFAS Ankle Hindfoot Scale were good or excellent in 23/42 (55%) in group A and in 30/34 (85%) in group B. Conclusion: Open reduction and internal fixation of intra-articular calcaneal fractures has become a standard surgical method. Fewer complications and better results related to treatment with locking compression plates confirmed in comparison to nonlocking ones were noted for all Sanders types of intra-articular calcaneal fractures. Age and Sanders type IV fractures are not considered to be the contraindications to surgery. PMID:19838350

Helicobacter pylori Eradication within 120 Days Is Associated with Decreased Complicated Recurrent Peptic Ulcers in Peptic Ulcer Bleeding Patients

2015-01-01

Background/Aims The connection between Helicobacter pylori and complicated peptic ulcer disease in peptic ulcer bleeding (PUB) patients taking nonsteroidal anti-inflammatory drugs has not been established. In this study, we sought to determine whether delayed H. pylori eradication therapy in PUB patients increases complicated recurrent peptic ulcers. Methods We identified inpatient PUB patients using the Taiwan National Health Insurance Research Database. We categorized patients into early (time lag ≤120 days after peptic ulcer diagnosis) and late H. pylori eradication therapy groups. The Cox proportional hazards model was used. The primary outcome was rehospitalization for patients with complicated recurrent peptic ulcers. Results Our data indicated that the late H. pylori eradication therapy group had a higher rate of complicated recurrent peptic ulcers (hazard ratio [HR], 1.52; p=0.006), with time lags of more than 120 days. However, our results indicated a similar risk of complicated recurrent peptic ulcers (HR, 1.20; p=0.275) in time lags of more than 1 year and (HR, 1.10; p=0.621) more than 2 years. Conclusions H. pylori eradication within 120 days was associated with decreased complicated recurrent peptic ulcers in patients with PUB. We recommend that H. pylori eradication should be conducted within 120 days in patients with PUB. PMID:25167793

ASD Closure in Structural Heart Disease.

Wiktor, Dominik M; Carroll, John D

2018-04-17

While the safety and efficacy of percutaneous ASD closure has been established, new data have recently emerged regarding the negative impact of residual iatrogenic ASD (iASD) following left heart structural interventions. Additionally, new devices with potential advantages have recently been studied. We will review here the potential indications for closure of iASD along with new generation closure devices and potential late complications requiring long-term follow-up. With the expansion of left-heart structural interventions and large-bore transseptal access, there has been growing experience gained with management of residual iASD. Some recently published reports have implicated residual iASD after these procedures as a potential source of diminished clinical outcomes and mortality. Additionally, recent trials investigating new generation closure devices as well as expanding knowledge regarding late complications of percutaneous ASD closure have been published. While percutaneous ASD closure is no longer a novel approach to managing septal defects, there are several contemporary issues related to residual iASD following large-bore transseptal access and new generation devices which serve as an impetus for this review. Ongoing attention to potential late complications and decreasing their incidence with ongoing study is clearly needed.

On Voxel based Iso-Tumor Control Probabilty and Iso-Complication Maps for Selective Boosting and Selective Avoidance Intensity Modulated Radiotherapy.

PubMed

Kim, Yusung; Tomé, Wolfgang A

2008-01-01

Voxel based iso-Tumor Control Probability (TCP) maps and iso-Complication maps are proposed as a plan-review tool especially for functional image-guided intensity-modulated radiotherapy (IMRT) strategies such as selective boosting (dose painting) and conformal avoidance IMRT. The maps employ voxel-based phenomenological biological dose-response models for target volumes and normal organs. Two IMRT strategies for prostate cancer, namely conventional uniform IMRT delivering an EUD = 84 Gy (equivalent uniform dose) to the entire PTV and selective boosting delivering an EUD = 82 Gy to the entire PTV, are investigated, to illustrate the advantages of this approach over iso-dose maps. Conventional uniform IMRT did yield a more uniform isodose map to the entire PTV while selective boosting did result in a nonuniform isodose map. However, when employing voxel based iso-TCP maps selective boosting exhibited a more uniform tumor control probability map compared to what could be achieved using conventional uniform IMRT, which showed TCP cold spots in high-risk tumor subvolumes despite delivering a higher EUD to the entire PTV. Voxel based iso-Complication maps are presented for rectum and bladder, and their utilization for selective avoidance IMRT strategies are discussed. We believe as the need for functional image guided treatment planning grows, voxel based iso-TCP and iso-Complication maps will become an important tool to assess the integrity of such treatment plans.

In past decades, the surgical techniques for treating laryngeal carcinoma have been vastly improved. For circumscribed tumors, voice-conserving resections are possible and for extensive neoplasms, radical laryngectomy, sometimes combined with chemoradiation, has been developed. Postoperative complications regarding swallowing function are not uncommon. Radiologic examinations, especially pharyngography and videofluoroscopy, are most often used to evaluate patients with complications after laryngeal surgery. An optimized videofluoroscopic technique for evaluation of complications is described. The radiologic appearance of early and late complications, such as fistulas, hematomas, aspiration, strictures, dysfunction of the pharyngoesophageal sphincter, tumor recurrence, and metachronous tumors is demonstrated.

Late complications after pharmacological stress echocardiography are infrequent but potentially dreadful events. We report the case of a 80-year-old woman admitted to hospital for rest chest pain with trivial troponin increase, normal left ventricular function and no significant ECG changes. A dobutamine stress echocardiography was performed for diagnostic purpose, with a negative result. About 30 min after the end of dobutamine infusion, she developed ST-segment elevation in inferior leads associated with chest pain and left ventricular dyssynergy, promptly resolved by sublingual nitrates. Subsequently, angiography documented the absence of significant coronary stenoses. The following clinical course was uneventful. Transient myocardial ischemia was likely due to dobutamine-induced coronary spasm. The case emphasizes the utility of routine, long-lasting monitoring of patients after stress echocardiography, even if negative, to counteract possible late life-threatening complications.

Gastric outlet obstruction is a complication that can occur in the evolution of patients with pancreatic adenocarcinoma. Self-expanding metal stents (SEMS) resolve this situation by endoscopy, thus avoiding a laparoscopic gastroenterotomy. The aim of our study is to report our experience in the palliative treatment with SEMS of gastroduodenal neoplasic obstruction at a monovalent gastroenterology institute in Mar del Plata. All patients with symptoms of gastric outlet obstruction of neoplasic origin who fit for SEMS between January 2006 and February 2011 were included. Data were collected regarding the patients' clinical characteristics as well as the type of tumor and the efficacy of the procedure measured according to success and complication rates, length of hospital stay and evaluation of clinical benefit, according to performance status scales and gastric outlet obstruction score (GOOS). A total of 17 prosthesis placed in 16 patients were analyzed. In all cases the procedure was completed successfully. The intervention was performed on an outpatient basis in 12 patients (75%). One patient presented within 7 days gastric haemorrhage related with the stent, who was early treated with argon plasma. Late expected com- plications due to prolonged survival were observed in 60% of patients. None of them was serious and resolved spontaneously or by endoscopic treatment. Average survival was 117 days (range 3 to 300 days) and most patients showed subjective improvement in GOOS scale. SEMS have a high rate of technical and clinical success. However, they are scarcely known in our field. They present an insignificant number of early complications and the resolution of later ones is quite easy. An improvement in GOOS scale and quality of life is achieved.

2011-05-01

The aim of this retrospective chart review of the patients who had septal surgery with or without turbinate surgery was to compare the postoperative complication rates according to the time of intranasal-splint (INS) removal. The data of 137 patients who underwent septal surgery with or without turbinate surgery at 2 different hospitals of Acıbadem Health Care Group between January 2007 and March 2009 were retrospectively evaluated. The patients who had these risk factors were eliminated, and 96 patients were included in this study. The patients were divided into 2 groups according to splint-removal time. The first group comprises patients whose nasal splints were removed in 24 hours after surgery, and the second group comprises patients whose splints were removed 5 days after the surgery. Any bleeding, septal hematoma, and synechia after pack removal were recorded. Analysis of the rate of complications was done with the χ test. Sixty-five male and 31 female patients with a mean age of 32.4 years (range, 18-57 years) were included in the study groups. Septal surgeries were performed in association with turbinate surgery in all 96 patients. These patients were divided into 2 groups. In the first group (n = 50), INSs were removed in 24 hours after surgery. In the second group (n = 46), INSs were removed 5 days after surgery. Bleeding within the first postoperative week was not recorded in both groups. Late bleeding was recorded in 2% (n = 1) of group 1 and in 2.17% (n = 1) in group 2. Septal hematoma and synechia were not recorded in none of the groups. The results were not statistically significant (P = 1). The routine use of INSs after septoplasty and removing them 24 hours after septoplasty are sufficient to avoid postoperative complications, and it minimizes postoperative discomfort.

Prematurity is the main reason for neonatal morbidity and mortality, and has become one of the greatest problems in public health, especially in developed countries. Prematurity rate has increased during the last 2 decades. This increase may be attributed to late preterm babies, that is, those with a gestational age between 34(+0) and 36(+6) weeks. Perinatal morbidities, as well as long term complications, are more frequent in this population than in term babies. The incidence is more similar to the one observed in earlier premature babies. The SEN34-36 group of the Spanish Society of Neonatology suggests these recommendations for the management of late preterm babies. Strategies are offered not only for the early detection of possible complications, but also for the correction of these morbidities, and from the point of view of a family and development centered care. Follow up is strongly recommended due to the high rate of late morbidities. Copyright © 2014 Asociación Española de Pediatría. Published by Elsevier Espana. All rights reserved.

Stress Generation, Avoidance Coping, and Depressive Symptoms: A 10-Year Model

2011-01-01

This study examined (a) the role of avoidance coping in prospectively generating both chronic and acute life stressors and (b) the stress-generating role of avoidance coping as a prospective link to future depressive symptoms. Participants were 1,211 late-middle-aged individuals (500 women and 711 men) assessed 3 times over a 10-year period. As predicted, baseline avoidance coping was prospectively associated with both more chronic and more acute life stressors 4 years later. Furthermore, as predicted, these intervening life stressors linked baseline avoidance coping and depressive symptoms 10 years later, controlling for the influence of initial depressive symptoms. These findings broaden knowledge about the stress-generation process and elucidate a key mechanism through which avoidance coping is linked to depressive symptoms. PMID:16173853

The self-expandable metallic stent (SEMS) is an excellent non-invasive tool for emergent bowel obstruction. This study was designed to evaluate the clinical usefulness of the SEMS for avoiding perioperative complications. We analyzed a total of 47 consecutive patients who had a bowel obstruction due to colorectal cancer at initial diagnosis between 2012 and 2017 from hospital records. Perioperative complications occurred in 30% (14/47) of patients. Univariate and multivariate logistic regression analyses identified an age of more than 75 years [p=0.037, OR=6.84 (95% CI=1.11-41.6)] and the absence of an SEMS treatment [p=0.028, OR=18.5 (95% CI=1.36-250.0)] as independent risk factors for perioperative complications. Pneumonia (12.7% (6/47)) was the most common complication. There were no pneumonia patients (0% (0/15)) who were treated with the SEMS. In contrast to patients with the non-SEMS treatment, 18.7% (6/32) of all patients and 35.7% (5/14) of elderly patients had pneumonia. The SEMS is a safe and effective treatment for avoiding perioperative complications, particularly pneumonia, and may be a crucial strategy in elderly patients with acute obstruction due to colorectal cancer.

Tanimoto, Ryuta; Cleary, Ryan C; Bagley, Demetrius H; Hubosky, Scott G

2016-03-01

Flexible and semirigid ureteroscopy (URS) are widely performed for the treatment of upper tract calculi and tumors. Ureteral avulsion is a rare, but devastating complication of endoscopic stone removal having multiple possible etiologies. Awareness and avoidance of this rare complication depend on identifying responsible mechanisms. This study examines the situations in which ureteral avulsion occurs as described anonymously in the Manufacturer and User facility Device Experience (MAUDE) database. The MAUDE database was systematically reviewed to account for all reported complications of flexible and semirigid URS. Keywords "ureteroscopy, injury, death, malfunction and other" were entered in the database and medical device reports were reviewed to capture any cases resulting in ureteral avulsion. Attention was paid to the type of ureteroscope involved and the mechanism for avulsion. A total of 104 entries were found detailing the reported complications of flexible and semirigid URS. Ureteral avulsion was clearly noted in six reports with flexible (2) and semirigid ureteroscopes (4). Potential mechanisms included locked deflection of a flexible ureteroscope (1), bunching of the distal bending rubber in a flexible ureteroscope (1), scabbard avulsion (3), and stone basketing (1). Although the incidence of ureteral avulsion cannot truly be determined from this study, some potentially novel mechanisms for this rare complication are observed. This may target future educational efforts to maximize awareness and avoidance of this complication.

The effect of antihyperglycaemic (antidiabetic) treatment on the late diabetic complications is one of the most important research areas in clinical diabetology. The relationship between glycaemic control and late micro- and macrovascular complications was highlighted by the results of the DCCT (Diabetes Control and Complications Trial) with type 1 and by the UKPDS (United Kingdom Prospective Diabetes Study) with type 2 diabetic patients. In these studies, observational follow-up investigations were also performed after the close-out of the randomized phase of the trial. In addition to these landmark studies, other randomized, controlled efficacy trials were also performed with observational follow-up investigations resulting in the development of the concept of metabolic memory or metabolic legacy. In this article, the main results of the studies are summarized. Orv Hetil. 2018; 159(15): 575-582.

Background Contact dermatitis, as a cutaneous complication after rhinoplasty, is of early onset, limited and transient. The cause of this dermatitis is irritant or allergic. Late onset skin complications are rare and non-inflammatory. Case presentation We are reporting an unexpected, severe allergic contact dermatitis of the face, in a young female, appearing one month following aesthetic rhinoplasty. She failed to respond to ordinary treatments for dermatitis. We did standard battery – including nitrofurazone, tincture of benzoin and hydrocortisone – patch test for the patient that showed sensitivity to benzoin and corticosteroid. Conclusions In summary we report a case of a severe allergic contact dermatitis of the face, in a 21-year-old girl who underwent corrective aesthetic rhinoplasty, appearing one month following surgical operation. We were unable to find a similar report in the medical literature. PMID:15056395

One hundred and six children undergoing antireflux surgery were studied; 41 were severely mentally retarded and 29 had reflux strictures. Although the eventual rate of success was 92%, 20 patients developed complications that required a second operation. Prolapse of the fundoplication into the mediastinum was the commonest complication (in seven patients), followed by intestinal obstruction (in five), and intractable fibrous oesophageal strictures (in five). The incidence of postoperative complications was highest in patients with mental retardation or oesophageal strictures. Referral of these patients for operation was invariably delayed, and earlier referral may have avoided many of the complications. PMID:4037858

Familial Mediterranean fever (FMF) is a genetically inherited autoinflammatory disorder characterized by inflammatory attacks and may result in amyloidosis as a severe complication. Elevation of acute phase reactants, including leukocytosis, is seen during attack periods. Here we describe a 13-year-old female patient with a very rare clinical presentation of FMF, who would experience FMF attacks when she did not regularly take her colchicine. During these attacks she had leukopenia and neutropenia instead of leukocytosis. The leukocyte count returned to normal when she continued the medication and avoided attacks. Ethnicity and clinical signs are important in leukopenic patientsand should be investigated for FMF to avoid unnecessary procedures and complications.

Distraction osteogenesis has revolutionised the management of craniofacial abnormalities. The technique however requires precise planning, patient selection, execution and follow-up to achieve consistent and positive results and to avoid unfavourable results. The unfavourable results with craniofacial distraction stem from many factors ranging from improper patient selection, planning and use of inappropriate distraction device and vector. The present study analyses the current standards and techniques of distraction and details in depth the various errors and complications that may occur due to this technique. The commonly observed complications of distraction have been detailed along with measures and suggestions to avoid them in clinical practice. PMID:24501455

Prevention of Portal Hypertension: from Variceal Development to Clinical Decompensation

Vorobioff, Julio D.; Groszmann, Roberto J

2015-01-01

Pharmacological treatment of portal hypertension (PH) has been exclusively devoted to gastro-esophageal varices related events at different frameworks including prophylactic, emergency or preventive therapy. The goals of treatment are to avoid the first bleeding episode, stop active bleeding and prevent bleeding recurrence, respectively. The objective of pre-primary prophylaxis (PPP) is to avoid variceal development and therefore, it necessarily deals with cirrhotic patients at earlier stages of the disease. At these earlier stages, nonselective beta blocker (NSBB) have been ineffective in preventing the development of varices and other complications of PH. Therefore, treatment should not rely on NSBB. It is possible, that at these earlier stages, etiological treatment of liver disease itself could prevent the progression of PH. This review will focus mainly on early treatment of PH, because if successful, it may translate into histological-hemodynamic improvements, avoiding not only variceal development but also other PH related complications, such as ascites and porto-systemic encephalopathy (PSE). Moreover, the advent of new therapies may allow not only the prevention of the complications of PH, but also the chance of a substantial degree of regression in the cirrhotic process with the possible prevention of hepatocellular carcinoma (HCC).

The rising popularity of surgery involving the laryngeal framework (surgical medialization of immobile vocal folds, vocal fold tightening, pitch variation, etc.) has resulted in increasing case experience. Little has appeared in the literature regarding complications or long-term results of this type of surgery. Several years' experience in a major referral center with various types of laryngeal framework surgery has led to a small number of complications. These have included late extrusion of the prosthesis and delayed hemorrhage. A review of these complications and recommendations for modification of technique to minimize them in the future are discussed.

Adverse events related to blood transfusion

The acute blood transfusion reactions are responsible for causing most serious adverse events. Awareness about various clinical features of acute and delayed transfusion reactions with an ability to assess the serious reactions on time can lead to a better prognosis. Evidence-based medicine has changed today's scenario of clinical practice to decrease adverse transfusion reactions. New evidence-based algorithms of transfusion and improved haemovigilance lead to avoidance of unnecessary transfusions perioperatively. The recognition of adverse events under anaesthesia is always challenging. The unnecessary blood transfusions can be avoided with better blood conservation techniques during surgery and with anaesthesia techniques that reduce blood loss. Better and newer blood screening methods have decreased the infectious complications to almost negligible levels. With universal leukoreduction of red blood cells (RBCs), selection of potential donors such as use of male donors only plasma and restriction of RBC storage, most of the non-infectious complications can be avoided.

The life expectancy of patients with disorders of consciousness (DOCs) is ever-increasing, but little is known about their clinical course over late stages. Several issues (premorbid conditions, complications and pressure sores) are to be considered for their effect on clinical outcome, risk of death and recovery of functional performance. Unfortunately, in late stages of long-term rehabilitation, these aspects are still more neglected than in acute and postacute stages. The aim of this study was to investigate the clinical course and the complications of patients in the late stages of DOCs and to explore the relationship between mortality and specific biomarkers. A total of 112 patients, admitted over 10 years in a dedicated ward, were retrospectively studied. Sociodemographic data, preadmission and inpatient clinical features were collected. Disability Rating Scale scores, complications including pressure sores and blood markers were assessed monthly. Data were analyzed through descriptive statistics and correlations using SPSS. Most patients were men older than 50 years with a nontraumatic etiology and a history of hypertension (42.86%). The most common complication was pneumonia (76.79%). No association was found between sex and mortality or between etiology and mortality (P > 0.05). Mortality correlated significantly with sepsis (ρ = 0.253), albumin (ρ = -0.558), hemoglobin (ρ = -0.354) and white blood cells (ρ = 0.243). Only 42% of patients remained unchanged at Disability Rating Scale evaluation. These data confirmed that DOCs are not static conditions and they require ongoing monitoring and assessment of clinical status, level of consciousness and laboratory biomarkers.

[Late respiratory function complications following burns].

PubMed

Ernesto, S; Marduel, Y; Freymond, N; Pacheco, Y; Devouassoux, G

2008-03-01

Twenty five per cent of thermal injuries are associated with secondary respiratory events linked to several mechanisms. In the acute phase of the accident oedema of the airways, the fume inhalation syndrome and ARDS are the most common causes responsible for death in 60% of cases. Late respiratory complications are little known and neglected. They comprise obstructive ventilatory defects due to the inhalation syndrome and restrictive defects secondary to ARDS or to dermal injury. We report the case of a female patient, extensively burnt 2 years previously, admitted to hospital with severe acute respiratory failure complicating COPD. The presence of both restrictive and obstructive defects led to the suggestion of alternative underlying mechanisms such as the pulmonary consequences of ARDS and extensive dermal scars. The latter were responsible for an armour like thickening of the skin of the thorax compatible with the restrictive defect. These functional abnormalities and the potential severity of acute respiratory failure are indications for regular pulmonary follow-up of patients with severe circumferential scarring of the thorax who are at high risk for respiratory complications.

Introduction of stapled hemorrhoidopexy (SH) brought a radical change in the treatment of haemorrhoidal disease. The aim of this study is to evaluate the results and the complications (early and late) from the use of this technique. During the last 6 years (2005-2011), 123 patients underwent a SH in our ward. Our sample consists of 79 male and 44 female patients with an average age of 48.2 years (range 22-83 years). Of them, 83 had third-degree haemorrhoidal disease, 34 had fourth-degree and 6 had second-degree bleeding haemorrhoids. The follow-up period was 6-72 months. Pain was minimal or even not existent. Additional sutures or use of adrenaline 1:200.000 for haemostasis were required in 6 patients (4.8%). The bleeding has been diminished with the use of this new haemorrhoidectomy stapler PPH03. Urinary retention, which was observed in 3 patients (2.4%), was temporary and the use of catheter was not needed. As a late complication, 'faecal urgency' occurred in 8 patients (6.5%), and disappeared after some months. No recurrent haemorrhoidal disease occurred. No cases of chronic pain were reported. Average hospital stay was 1 day, except for 2 patients who remained for 2 days for bleeding observation. The correct application of SH reduces the possible complications. The advantages of the stapled procedure are reduced postoperative pain, the minimal hospital stay and early return to work.

Our aim in this study was to report our single-center experience with direct percutaneous jejunostomy over a 4-year period with regard to technical success rate, immediate and late complications, and patient tolerance of the procedure. Institutional records of 22 consecutive patients who underwent radiological insertion of a percutaneous jejunostomy for a variety of indications were reviewed. The proximal jejunum was punctured under either fluoroscopic or ultrasonic guidance, and following placement of retention sutures, a 10- to 12-Fr catheter inserted. There was a 100% technical success rate in placement involving a total of seven operators. The indications for placement were prior gastric resection, newly diagnosed resectable esophageal or gastric carcinoma, unresectable gastric carcinoma with outlet obstruction, and palliative drainage of bowel obstruction. Mean duration of follow-up was 100 days, and catheter placement 57.7 days. There were six minor early complications, consisting of loss of two retention anchors requiring repuncture, three cases of localized excessive postprocedural pain, and one failed relief of symptoms of small bowel obstruction. Four tubes developed late complications (two blocked, one catheter cracked, and one inadvertently pulled out). Three of the four were successfully replaced through the existing tracts. One patient subsequently developed a minor skin infection, while another developed late pericatheter leakage from ascites. We conclude that direct percutaneous jejunostomy is a valuable treatment modality applicable to a number of clinical scenarios, with a high technical success rate and low serious complication rate.

Late Presentation of Recurrent Monomorphic Ventricular Tachycardia following Minimally Invasive Mitral Valve Repair due to Epicardial Injury.

We report a 73-year-old male with late onset monomorphic ventricular tachycardia following mitral valve repair (MVR). Typically, injury to epicardial arteries following mitral valve repair/replacement presents immediately as ventricular tachycardia/fibrillation, difficulty weaning from cardiopulmonary bypass, worsening ECG changes, increasing cardiac biomarkers, or new wall motion abnormalities. Our case illustrates a "late complication" of a distorted circumflex artery following mitral valve repair and the importance of early diagnostic angiography and percutaneous intervention.

Parenteral nutrition is a life-saving modality, but one that also carries risks for potentially life-threatening complications. Comprehensive management of patients receiving parenteral nutrition includes careful selection of candidates, individualizing formulas to meet patients' unique needs, monitoring response to therapy, and implementing strategies designed to avoid complications. Measures to mitigate the risk of central line-associated bloodstream infections are particularly important. As with all complex therapies, a collaborative, multidisciplinary approach promotes optimal outcomes.

We describe 2 unusual cases of vaginal dehiscence after intracavitary brachytherapy performed following robotic laparoscopic hysterectomy (RLH) along with their management. This unusual complication, which may be more common because of the robotic procedures, can be prevented by careful examination and possible delay of the onset of brachytherapy, if indicated. Our report reviews techniques of avoiding this complication and suggests that these complications should be discussed with the patients. PMID:23349653

Post-ERCP acute pancreatitis and its risk factors.

Iorgulescu, A; Sandu, I; Turcu, F; Iordache, N

2013-03-15

Endoscopic retrograde cholangiopancreatography (ERCP) is a complex endoscopic technique that evolved from a diagnostic to a mainly therapeutic procedure. This was due to the identification of post-procedural complications that can follow both simple ERCP and that associated with the instrumentation of the biliary and pancreatic ductals. The identification of post ERCP complications in a proportion of 5 to 10% of cases, with a mortality rate of 0.33%, imposed their analysis and study of risk factors involved in their occurrence. The significance of post ERCP complications reveals the necessity of their avoidance by adopting additional measures if risk factors are identified. We have retrospectively analyzed 900 cases that underwent ERCP in the Surgery Department of "Sf. Ioan" Clinical Hospital in a period of 17 years. The complications of the procedure were studied. Among them, a special attention was given to post-ERCP acute pancreatitis (pERCP-AP), the most common complication that occurred in the study group. We also tried to find out and highlight the risk factors for this complication. ERCP is a relatively safe invasive procedure, yet it has complications (8% of cases), some of them potentially fatal (mortality 0.43%). The most common complications after ERCP are acute pancreatitis (3.7%), papillary bleeding (1.04%), retroperitoneal duodenal perforation (0.69%) and biliary septic complications like acute cholecystitis and cholangitis (1.21%). Acute pancreatitis is by far the most common complication. Risk factors for its occurrence are difficult sphincterotomy with precut use, failure of CBD desobstruction, pancreatic sphincterotomy, repeated injection of contrast in the pancreatic ductal system, dysfunction of the sphincter of Oddi and the absence of changes of chronic pancreatitis. When risk factors are identified, the patients' selection must be very strict and diagnostic ERCP should be avoided in favor of non-invasive diagnostic methods (MRI-cholangiography, echo-endoscopy).

Recurrent gastric perforation as a late complication of radiotherapy for mucosa-associated lymphoid tissue lymphoma of the stomach.

Radiation therapy can be used to treat Helicobacter pylori-negative or eradication-refractory extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) of the stomach. We report a case of gastric perforation which occurred more than 1 year after the completion of radiotherapy for H. pylori eradication-refractory gastric MALT lymphoma, and then recurred shortly afterwards. This was considered to be a late complication of radiation toxicity. Although gastric perforation due to radiotherapy has been reported very rarely in the past, even in advanced disease, this case shows that perforation can develop in patients with superficial disease and can relapse.

Self-esteem in Early Adolescence as Predictor of Depressive Symptoms in Late Adolescence and Early Adulthood: The Mediating Role of Motivational and Social Factors.

Ample research has shown that low self-esteem increases the risk to develop depressive symptoms during adolescence. However, the mechanism underlying this association remains largely unknown, as well as how long adolescents with low self-esteem remain vulnerable to developing depressive symptoms. Insight into this mechanism may not only result in a better theoretical understanding but also provide directions for possible interventions. To address these gaps in knowledge, we investigated whether self-esteem in early adolescence predicted depressive symptoms in late adolescence and early adulthood. Moreover, we investigated a cascading mediational model, in which we focused on factors that are inherently related to self-esteem and the adolescent developmental period: approach and avoidance motivation and the social factors social contact, social problems, and social support. We used data from four waves of the TRAILS study (N = 2228, 51% girls): early adolescence (mean age 11 years), middle adolescence (mean age 14 years), late adolescence (mean age 16 years), and early adulthood (mean age 22 years). Path-analyses showed that low self-esteem is an enduring vulnerability for developing depressive symptoms. Self-esteem in early adolescence predicted depressive symptoms in late adolescence as well as early adulthood. This association was independently mediated by avoidance motivation and social problems, but not by approach motivation. The effect sizes were relatively small, indicating that having low self-esteem is a vulnerability factor, but does not necessarily predispose adolescents to developing depressive symptoms on their way to adulthood. Our study contributes to the understanding of the mechanisms underlying the association between self-esteem and depressive symptoms, and has identified avoidance motivation and social problems as possible targets for intervention.

Survival rates after allogeneic hematopoietic cell transplantation (HCT) for Fanconi anemia (FA) have increased dramatically since 2000. However, the use of autologous stem cell gene therapy, whereby the patient's own blood stem cells are modified to express the wild-type gene product, could potentially avoid the early and late complications of allogeneic HCT. Over the last decades, gene therapy has experienced a high degree of optimism interrupted by periods of diminished expectation. Optimism stems from recent examples of successful gene correction in several congenital immunodeficiencies, whereas diminished expectations come from the realization that gene therapy will not be free of side effects. The goal of the 1st International Fanconi Anemia Gene Therapy Working Group Meeting was to determine the optimal strategy for moving stem cell gene therapy into clinical trials for individuals with FA. To this end, key investigators examined vector design, transduction method, criteria for large-scale clinical-grade vector manufacture, hematopoietic cell preparation, and eligibility criteria for FA patients most likely to benefit. The report summarizes the roadmap for the development of gene therapy for FA.

Excluded segmental duct bile leakage: the case for bilio-enteric anastomosis.

2014-06-01

Excluded segmental duct bile leak is the rarest type of post-hepatectomy bile leak and presents unique diagnostic and management features. Classical management strategies invariably entail a significant loss of functioning hepatic parenchyma. The aim of this study is to report a new liver-sparing technique to handle excluded segmental duct bile leakage. Two cases of excluded segmental duct bile leak occurring after major hepatic resection were managed by a Roux-en-Y hepatico-jejunostomy on the excluded segmental duct, avoiding the sacrifice of the liver parenchyma origin of the fistula. In both cases, classical management strategies would have led to the functional loss of roughly 50 % of the liver remnant. Diagnostic and management implications are thoroughly discussed. Both cases had an uneventful postoperative course. The timing of repair was associated with a different outcome: the patient who underwent surgical repair in the acute phase developed no long-term complications, whereas the patient who underwent delayed repair developed a late stenosis requiring percutaneous dilatation. Roux-en-Y hepatico-jejunostomy on the excluded bile duct is a valuable technique in selected cases of excluded segmental duct bile leakage.

Optimizing prophylactic treatment of migraine: Subtypes and patient matching

PubMed Central

Dib, Michel

2008-01-01

Advances in our understanding of the pathophysiology of migraine have resulted in important breakthroughs in treatment. For example, understanding of the role of serotonin in the cerebrovascular circulation has led to the development of triptans for the acute relief of migraine headaches, and the identification of cortical spreading depression as an early central event associated wih migraine has brought renewed interest in antiepileptic drugs for migraine prophylaxis. However, migraine still remains inadequately treated. Indeed, it is apparent that migraine is not a single disease but rather a syndrome that can manifest itself in a variety of pathological conditions. The consequences of this may be that treatment needs to be matched to particular patients. Clinical research needs to be devoted to identifying which sort of patients benefit best from which treatments, particularly in the field of prophylaxis. We propose four patterns of precipitating factors (adrenergic, serotoninergic, menstrual, and muscular) which may be used to structure migraine prophylaxis. Finally, little is known about long-term outcome in treated migraine. It is possible that appropriate early prophylaxis may modify the long-term course of the disease and avoid late complications.

Late recurrent peripheral upper limb ischemia after non-union of a clavicle fracture.

Stella, Marco; Santolini, Emmanuele; Briano, Stefania; Santolini, Federico

2015-12-01

A 74-year-old woman was referred to our hospital due to recurrent episodes of upper limb ischemia. Her past medical history included a clavicle non-union developed after a clavicle midshaft fracture that had occurred 30 years previously. After a long asymptomatic period, she started showing symptoms of chronic ischemia to the left arm that were misdiagnosed. Thoracic outlet syndrome (TOS) is a rare but possible complication of mal-union and non-union of clavicle fractures; symptoms related to arterial involvement (ATOS) amount to less than 1% of all existing forms of thoracic outlet syndrome. In case of clavicle non-union, local instability plays a key role in determining the initial injury to the vessels and the recurrence of symptoms. Restoration of local bone stability and anatomy, obtained by compression plating and autologous bone grafting, combined with an appropriate vascular surgery, is essential to achieve a clinical resolution of symptoms and to avoid the recurrence of symptomatology as seen in the herein case.

On Voxel based Iso-Tumor Control Probabilty and Iso-Complication Maps for Selective Boosting and Selective Avoidance Intensity Modulated Radiotherapy

PubMed Central

Kim, Yusung; Tomé, Wolfgang A.

2010-01-01

Summary Voxel based iso-Tumor Control Probability (TCP) maps and iso-Complication maps are proposed as a plan-review tool especially for functional image-guided intensity-modulated radiotherapy (IMRT) strategies such as selective boosting (dose painting) and conformal avoidance IMRT. The maps employ voxel-based phenomenological biological dose-response models for target volumes and normal organs. Two IMRT strategies for prostate cancer, namely conventional uniform IMRT delivering an EUD = 84 Gy (equivalent uniform dose) to the entire PTV and selective boosting delivering an EUD = 82 Gy to the entire PTV, are investigated, to illustrate the advantages of this approach over iso-dose maps. Conventional uniform IMRT did yield a more uniform isodose map to the entire PTV while selective boosting did result in a nonuniform isodose map. However, when employing voxel based iso-TCP maps selective boosting exhibited a more uniform tumor control probability map compared to what could be achieved using conventional uniform IMRT, which showed TCP cold spots in high-risk tumor subvolumes despite delivering a higher EUD to the entire PTV. Voxel based iso-Complication maps are presented for rectum and bladder, and their utilization for selective avoidance IMRT strategies are discussed. We believe as the need for functional image guided treatment planning grows, voxel based iso-TCP and iso-Complication maps will become an important tool to assess the integrity of such treatment plans.

Objective To assess the technical success and complication rates of the radiologic placement of central venous ports via the internal jugular vein. Materials and Methods We retrospectively reviewed 1254 central venous ports implanted at our institution between August 2002 and October 2009. All procedures were guided by using ultrasound and fluoroscopy. Catheter maintenance days, technical success rates, peri-procedural, as well as early and late complication rates were evaluated based on the interventional radiologic reports and patient medical records. Results A total of 433386 catheter maintenance days (mean, 350 days; range 0-1165 days) were recorded. The technical success rate was 99.9% and a total of 61 complications occurred (5%), resulting in a post-procedural complication rate of 0.129 of 1000 catheter days. Among them, peri-procedural complications within 24 hours occurred in five patients (0.4%). There were 56 post-procedural complications including 24 (1.9%, 0.055 of 1000 catheter days) early and 32 (2.6%, 0.074 of 1000 catheter days) late complications including, infection (0.6%, 0.018 of 10000 catheter days), thrombotic malfunction (1.4%, 0.040 of 1000 catheter days), nonthrombotic malfunction (0.9%, 0.025 of 1000 catheter days), venous thrombosis (0.5%, 0.014 of 1000 catheter days), as well as wound problems (1.1%, 0.032 of 1000 catheter days). Thirty six CVPs (3%) were removed due to complications. Bloodstream infections and venous thrombosis were the two main adverse events prolonging hospitalization (mean 13 days and 5 days, respectively). Conclusion Radiologic placement of a central venous port via the internal jugular vein is safe and efficient as evidenced by its high technical success rate and a very low complication rate.

This study aims to investigate indications and complications of permanent cardiac pacing in adults with congenital heart disease (CHD). Two-hundred and seventy-four CHD patients were identified who underwent permanent pacemaker implantation between 1972 and 2009. The indication for pacing was acquired sinus node or AV node conduction disease (63%), sinus node or AV node conduction disease after cardiac surgery (28%), and drug/arrhythmia-related indications (9%). Patients with complex CHD received a pacemaker at younger age (23 versus 31 years, p<0.0001) and more often received an epicardial pacing system (51% versus 23%, p<0.0001) compared to those with simple or moderate CHD. Twenty-nine patients (10.6%) had a periprocedural complication during the primary pacemaker implantation (general population: 5.2%). The most common acute complications were lead dysfunction (4.0%), bleeding (2.6%), pocket infection (1.5%) and pneumothorax (1.5%). During a median follow-up of 12 years, pacemaker-related complications requiring intervention occurred in 95 patients (34.6%). The most common late pacemaker-related complications included lead failure (24.8%), pacemaker dysfunction/early battery depletion (5.1%), pacemaker migration (4.7%) and erosion (4.7%). Pacemaker implantation at younger age (<18 years) was an independent predictor of late pacemaker-related complication (adjusted hazard ratio 1.68, 95% confidence interval 1.07 to 2.63, p=0.023). The risk of periprocedural complications seems higher in the CHD population compared to the general population and more than one-third of CHD patients encountered a pacemaker-related complication during long-term follow-up. This risk increases for those who receive a pacemaker at younger age. Crown Copyright © 2013. Published by Elsevier Ireland Ltd. All rights reserved.

A rare cause of late onset neurological deficit in post tuberculous kyphotic deformity—case report

Late onset neurological deficit is a rare complication of spinal tuberculosis. Reactivation of the disease and compression by internal gibbus are the common causes for late onset neurological deficit. We report a rare cause of late onset paraplegia in a patient with post tubercular kyphotic deformity. The late onset neurological deficit was due to the adjacent segment degeneration proximal to the kyphotic deformity. Posterior hypertrophied ligamentum flavum and anterior disc osteophyte complex caused the cord compression. The increased stress for prolonged period at the end of the deformity was the reason for the accelerated degeneration. Patient underwent posterior decompression, posterolateral and interbody fusion. Deformity correction was not done. To our best knowledge, this is only the second report of this unusual cause of late onset paraplegia. PMID:29354759

Late-onset noninfectious pulmonary complication after allogenic hematopoietic stem cell transplantation is an important contributing factor associated with high rate morbidity and mortality. We report a case with pleuroparenchymal fibroelastosis (PPFE) occurred after allogenic bone marrow transplantation. The onset was infiltrative shadows in upper lobes, and the haziness spread gradually throughout the lungs with recurrent episodes of pneumothorax in both lungs. Progressive respiratory failure in course of adrenocortical steroid administration eventually caused death. Histological examination in general autopsy showed patchy subpleural fibrosis predominantly distributed in the upper lobes with substantial density rise of elastic fibers in the subpleural area, consistent with the diagnosis of PPFE. PPFE after allogenic transplantation has been seldom reported to date, but it is one of the most important histological components of late-onset noninfectious pulmonary complication after allogenic transplantation characterized by recurrent pneumothorax. Retrospective analysis in our case indicates early diagnosis may be possible by histological evaluation of elastic fibers in lung specimen when pneumothorax is treated surgically. This case suspects that it is important for hematologist and pathologist to aware this progressive disease along with information of histological characteristics, therefore, leading to the establishment of therapeutic strategies and the improvement of poor prognosis.

Increased thromboplastic potential in diabetes: a multifactorial phenomenon.

1987-07-01

Coagulation parameters, platelet aggregation, and thromboxane production as well as metabolic parameters were measured in 31 diabetic patients, 12 without and 19 with clinically manifest late complications, and in 14 healthy control subjects. Spontaneous in vitro aggregation as well as ADP, collagen, and arachidonic acid induced aggregation were higher in both groups of diabetic patients, without an increase in thromboxane B2 production. In diabetic patients with late complications an increase in fibrinogen, fibrinogen cyanogen bromide peptide, factor VIII related antigen, C1-esterase inhibitor, and antithrombin III was observed in comparison to healthy subjects. Fibrinogen, C1-esterase inhibitor, and factor VIII related antigen were already elevated in diabetic patients without clinically manifest late vascular complications. No strict correlations were found between serum glucose, glycosylated hemoglobin, and glycosylated albumin, on the one hand, and coagulation promoting or inhibiting factors, aggregation or thromboxane B2 production, on the other, in either control or diabetic subjects. Also no correlations existed between the coagulation parameters and the aggregation results. In vitro incubation of pooled normal plasma with different glucose concentrations had no influence on the methods by which the coagulation parameters were measured. These data indicate that rather early in the diabetic state many changes take place in different phases of the thrombostatic process, all resulting in an increased hemostatic diathesis.

Obesity in women of reproductive age is increasing in prevelance worldwide. Obesity reduces fertility and increases time taken to conceive, and obesity-related comorbidities (such as type 2 diabetes and chronic hypertension) heighten the risk of adverse outcomes for mother and child if the woman becomes pregnant. Pregnant women who are obese are more likely to have early pregnancy loss, and have increased risk of congenital fetal malformations, delivery of large for gestational age infants, shoulder dystocia, spontaneous and medically indicated premature birth, and stillbirth. Late pregnancy complications include gestational diabetes and pre-eclampsia, both of which are associated with long-term morbidities post partum. Women with obesity can also experience difficulties during labour and delivery, and are more at risk of post-partum haemorrhage. Long-term health risks are associated with weight retention after delivery, and inherent complications for the next pregnancy. The wellbeing of the next generation is also compromised. All these health issues could be avoided by prevention of obesity among women of reproductive age, which should be viewed as a global public health priority. For women who are already obese, renewed efforts should be made towards improved management during pregnancy, especially of blood glucose, and increased attention to post-partum weight management. Effective interventions, tailored to ethnicity and culture, are needed at each of these stages to improve the health of women and their children in the context of the global obesity epidemic.

To examine whether the real-time ultrasound-guided venipuncture for implantable venous port placement is safer than the traditional venipuncture. The study analyzed the results of 2153 venous ports placed consecutively from January 2009 to January 2016. A total of 922 patients in group 1 and 1231 patients in group 2 were admitted with venous port placed using the traditional landmark subclavian approach and real-time ultrasound-guided axillary approach, respectively. Sociodemographic characteristics of patients, early (pneumothorax, pinch-off syndrome, arterial puncture, hematoma, and malposition arrhythmia) and late (deep vein thrombosis, obstruction, infection, erosion-dehiscence, and rotation of the port chamber) complications and the association of these complications with the implantation method were evaluated. There were no significant differences in the sociodemographic characteristics of the patients between the two groups. The overall and early complications in group 2 were significantly lower than those in group 1. Pinch-off syndrome only developed in group 1. Seven patients and two patients had pneumothorax in groups 1 and 2, respectively. Puncture number was significantly associated with the development of the overall complications. The ultrasound-guided axillary approach may be preferred as a method to reduce the risk of both early and late complications. Large, randomized, controlled prospective trials will be helpful in determining a safer implantable venous port implantation technique.

Lumbar total disc replacement (LTDR) is considered for the treatment of lumbar degenerative disc disease with the hope that by preserving motion the long-term fusion complication of adjacent segment disease can be avoided. The complications of LTDR can be divided into approach-related and long-term complications. Very little has been described about the complications and treatment for complications more than 10 years after the device has been implanted. Here we describe a tranforaminal endoscopic discectomy procedure for a patient presenting with foot drop twelve years after a L5-S1 total disc replacement. Copyright © 2018.

2016-01-01

Cervical spine surgery performed for the correct indications yields good results. However, surgeons need to be mindful of the many possible pitfalls. Complications may occur starting from the anaesthestic procedure and patient positioning to dura exposure and instrumentation. This review examines specific complications related to anterior and posterior cervical spine surgery, discusses their causes and considers methods to prevent or treat them. In general, avoiding complications is best achieved with meticulous preoperative analysis of the pathology, good patient selection for a specific procedure and careful execution of the surgery. Cervical spine surgery is usually effective in treating most pathologies and only a reasonable complication rate exists. PMID:27114784

Transverse rectus abdominus myocutaneous (TRAM) flap is one of the commonly used techniques for breast reconstruction. Postoperative pain relief is of paramount importance following TRAM flap breast reconstruction to avoid potentially preventable complications like chest infection. Several methods of pain control are available, including intrapleural anesthesia. Here we report a case of a patient who developed ventricular standstill as a complication of intrapleural bupivacaine.

The purpose of this study was to report long-term disease control and late radiation toxicity for patients reirradiated for head and neck cancer. We conducted a retrospective analysis of 137 patients reirradiated with a prescribed dose ≥45 Gy between 1986 and 2013 for a recurrent or second primary malignancy. Endpoints were locoregional control, overall survival (OS), and grade ≥4 late complications according to European Organization for Research and Treatment of Cancer (EORTC)/Radiation Therapy Oncology Group (RTOG) criteria. Five-year locoregional control rates were 46% for patients reirradiated postoperatively versus 20% for patients who underwent reirradiation as the primary treatment (p < .05). Sixteen cases of serious (grade ≥4) late toxicity were seen in 11 patients (actuarial 28% at 5 years). In patients reirradiated with intensity-modulated radiotherapy (IMRT), a borderline improved locoregional control was observed (49% vs 36%; p = .07), whereas late complication rates did not differ. Reirradiation should be considered for patients with a recurrent or second primary head and neck cancer, especially postoperatively, if indicated. © 2017 Wiley Periodicals, Inc.

2016-04-01

Cytomegalovirus (CMV) infection remains a common infection after solid-organ transplantation. In the general population CMV disease is associated with Guillain-Barre syndrome (GBS), an autoimmune disease leading to an acute peripheral neuropathy, in 1 of 1000 cases. Interestingly, GBS is a rarely observed complication in solid-organ transplant recipients, possibly related to maintenance immunosuppression. We describe a case of CMV infection complicated by GBS in a kidney transplant recipient and review the literature.

The purpose of this study was to determine whether exposure to stressful life events was associated with changes in levels of circulating cortisol during pregnancy in a population of 603 pregnant women. The participating pregnant women filled out a questionnaire and collected a morning and evening sample of saliva in early pregnancy (median 14th gestational week) and in late pregnancy (median and 30th gestational week). They were asked to report the number of life events experienced during first and second trimester, respectively, and were asked to rate the intensity of the experienced events. Complications related to the pregnancy such as vaginal bleeding and suspected growth retardation were registered and the women were asked about concerns about their pregnancy. The salivary samples were analyzed for cortisol and the levels were higher in late than in early pregnancy. In late pregnancy women exposed to more than one life event or were concerned about pregnancy complications during second trimester had a higher evening cortisol level, whereas morning values were unaffected. After adjustment for smoking women who experienced more than one very stressful life event had 27% higher evening cortisol concentrations (95% confidence intervals: 1-59%). Women with worries about pregnancy complications had 27% (95% confidence intervals: 2-57%) higher levels. In early pregnancy women reporting stressful life events did not have higher evening cortisol levels, but tended to have a blunted morning HPA response. In conclusion, we found differences in the associations between chronic stress in early and late pregnancy and cortisol levels indicating that the response to chronic stress is dependent on the stage of the pregnancy.

Peeters, Stephanie T.H.; Lebesque, Joos V.; Heemsbergen, Wilma D.

2006-03-15

Purpose: To identify dosimetric parameters derived from anorectal, rectal, and anal wall dose distributions that correlate with different late gastrointestinal (GI) complications after three-dimensional conformal radiotherapy for prostate cancer. Methods and Materials: In this analysis, 641 patients from a randomized trial (68 Gy vs. 78 Gy) were included. Toxicity was scored with adapted Radiation Therapy Oncology Group/European Organization for the Research and Treatment of Cancer (RTOG/EORTC) criteria and five specific complications. The variables derived from dose-volume histogram of anorectal, rectal, and anal wall were as follows: % receiving {>=}5-70 Gy (V5-V70), maximum dose (D{sub max}), and mean dose (D{sub mean}).more » The anus was defined as the most caudal 3 cm of the anorectum. Statistics were done with multivariate Cox regression models. Median follow-up was 44 months. Results: Anal dosimetric variables were associated with RTOG/EORTC Grade {>=}2 (V5-V40, D{sub mean}) and incontinence (V5-V70, D{sub mean}). Bleeding correlated most strongly with anorectal V55-V65, and stool frequency with anorectal V40 and D{sub mean}. Use of steroids was weakly related to anal variables. No volume effect was seen for RTOG/EORTC Grade {>=}3 and pain/cramps/tenesmus. Conclusion: Different volume effects were found for various late GI complications. Therefore, to evaluate the risk of late GI toxicity, not only intermediate and high doses to the anorectal wall volume should be taken into account, but also the dose to the anal wall.« less

Development of an attachment-informed measure of sexual behavior in late adolescence.

Szielasko, Alicia L; Symons, Douglas K; Lisa Price, E

2013-04-01

There is considerable interest in relations between sexual behavior and romantic attachment styles in adolescence as attachment needs are increasingly met through intimate partners rather than parents. The objectives of this research were to organize a measure of sexual behavior within an attachment theory framework, and then show that this new measure uniquely predicted sexual approach styles and invasive sexual experiences. 190 18- and 19-year-old university students in late adolescence completed sexual behavior items that were provided ambivalent (anxious) and avoidant dimensions. These were systematically related to the romantic attachment dimensions of the Experiences in Close Relationships - Revised. However, even after romantic relationship style, gender, and social desirability were controlled, avoidance in sexual relationships predicted lifetime sexual partner number and negatively predicted positive sexual strategies, and ambivalence in sexual relationships predicted invasive and coercive sexual behaviors. A measure specific to sexual relationships informs the attachment and romantic context of sex in late adolescence. Copyright © 2013 The Foundation for Professionals in Services for Adolescents.

[Late outlet strut fracture of an aortic Björk-Shiley and embolization of the prosthetic disc].

1988-09-01

A new case of late fracture of an outlet strut in a convexo-concave Björk-Shiley valve is reported. The fracture occurred 6 years after aortic implantation of the valve and was responsible for aorto-iliac embolization by the prosthetic disc and death of the patient from cardiogenic shock. This not uncommon complication of the Björk-Shiley valve prosthesis is usually ascribed to the relative fragility of its outlet strut welded to the metallic ring and subjected to strong pressures. Although most cases were observed within the first two years of prosthetic valve insertion, and mainly with valves manufactured in 1981 and 1982, our case and a few others demonstrate the possibility of late rupture. Cardiologists must be aware of this possible complication, since in some favourable cases it can be diagnosed at an early stage and the patient's life can be saved by an emergency operation.

This study evaluated the short-term cost-effectiveness of the Patient Empowerment Programme (PEP) for diabetes mellitus (DM) in Hong Kong. Propensity score matching was used to select a matched group of PEP and non-PEP subjects. A societal perspective was adopted to estimate the cost of PEP. Outcome measures were the cumulative incidence of all-cause mortality and diabetic complication over a 5-year follow-up period and the number needed to treat (NNT) to avoid 1 event. The incremental cost-effectiveness ratio (ICER) of cost per event avoided was calculated using the PEP cost per subject multiplied by the NNT. The PEP cost per subject from the societal perspective was US$247. There was a significantly lower cumulative incidence of all-cause mortality (2.9% vs 4.6%, P < .001), any DM complication (9.5% vs 10.8%, P = .001) and CVD events (6.8% vs 7.6%, P = .018), in the PEP group. The costs per death from any cause, DM complication or case of CVD avoided were US$14 465, US$19 617 and US$30 796, respectively. The extra amount allocated to managing PEP was small and it appears cost-effective in the short-term as an addition to RAMP. © 2017 John Wiley & Sons Ltd.

Despite the dramatic decrease of mortality rate among children with bacterial meningitis in recent decades, some patients are left with neurologic sequelae. The purpose of this study was to analyze the occurrence of seizures as predictors for meningitis-related deaths or neurological sequelae including late seizures. This study uses a retrospective chart review of 277 children (aged 0-16 years, median 2 years, 162 boys) treated for bacterial meningitis in University Clinical Centre in Prishtina (Kosovo). Of the 277 children treated for bacterial meningitis, 60 children (22%) manifested seizures prior to admission, 57 children (21%) had seizures after admission, and late seizures were diagnosed in 24 children (9%). The risk for adverse outcome was significantly higher in patients who had seizures prior to admission (52/60) and in patients who manifested seizures later than 24 h (41/41; RR 8.17 and 6.78 respectively, p < 0.0001). All children who manifested late seizures were diagnosed with meningitis-related acute neurologic complications: subdural effusion (18), hydrocephalus (6), intracranial bleeding (1), and subdural empyema (2). Of the 60 children who presented seizures prior to admission, only 11 manifested late seizures. Seizures prior to admission were predictors of high risk of adverse outcome in bacterial meningitis in children. The risk of secondary epilepsy (9%) occurred only in children with evident structural neurologic complications during the acute phase of bacterial meningitis.

The purpose of this study was to evaluate the long-term results of partial arch repair using the frozen elephant trunk (FET) technique for distal arch aortic aneurysm and to examine the late complications. Thirty-eight patients with true distal arch aortic aneurysms were repaired with FET introduced through an incision in the proximal arch aorta. Follow-up computed tomography was performed every 6 or 12 months in 36 surviving patients. The maximum dimension of the excluded aneurysmal space was measured to determine whether the aneurysmal space had decreased or disappeared. Late complications were also evaluated during the long-term follow-up. There was 1 hospital death (2.6%) and 1 (2.6%) case of paraplegia. There were 2 late sudden deaths (5.2%) thought to be due to aneurysm rupture and arrhythmia. Postoperative serial-computed tomography showed shrinkage of the excluded aneurysmal space in 33 of 36 patients. Late aneurysmal formation occurred in the anastomotic site in three patients. One patient underwent thoracic endovascular stent grafting 10 years after surgery, 1 patient had total arch replacement 9 years after surgery, and 1 died due to rupture. Frozen elephant trunk was found to be a useful alternative for treating true distal arch aortic aneurysm. However, we must be alert for late aneurysmal formation at the incision site.

2010-12-01

Systemic complications secondary to subarachnoid hemorrhage from an aneurysm are common (40%) and the mortality attributable to them (23%) is comparable to mortality from the primary lesion, rebleeding, or vasospasm. Although nonneurologic medical complications are avoidable, they worsen the prognosis, lengthen the hospital stay, and generate additional costs. The prevention, early detection, and appropriate treatment of systemic complications will be essential for managing the individual patient's case. Treatment should cover major symptoms (headache, nausea, and dizziness) and ambient noise should be reduced, all with the aim of achieving excellence and improving the patient's perception of quality of care.

Sublingual pyramidal lobe. Complications of subtotal thyroidectomy for Graves' disease

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

Sternberg, J.L.

1986-11-01

A potential complication of subtotal thyroidectomy where a large pyramidal lobe is present is described. The pyramidal lobe normally is immobilized inferiorly by its attachment to the thyroidal isthmus. When the isthmus is removed and the pyramidal lobe is left in situ during subtotal thyroidectomy its superior attachments will allow the pyramidal lobe to become situated sublingually. This may produce gagging and nausea. To avoid the complication, it is recommended that the pyramidal lobe be removed during subtotal thyroidectomy. If the patient also is thyrotoxic, I-131 can be used to treat this complication successfully.

Colostomy closure: how to avoid complications

Purpose Colostomy is an operation frequently performed in pediatric surgery. Despite its benefits, it can produce significant morbidity. In a previous publication we presented our experience with the errors and complications that occurred during cases of colostomy creation. We now have focused in the morbidity related to the colostomy closure. The technical details that might have contributed to the minimal morbidity we experienced are described. Methods The medical records of 649 patients who underwent colostomy closure over a 28-year period were retrospectively reviewed looking for complications following these procedures. Our perioperative protocol for colostomy closure consisted in: clear fluids by mouth and repeated proximal stoma irrigations 24 h prior to the operation. Administration of IV antibiotics during anesthesia induction and continued for 48 h. Meticulous surgical technique that included: packing of the proximal stoma, plastic drape to immobilize the surgical field, careful hemostasis, emphasis in avoiding contamination, cleaning the edge of the stomas to allow a good 2-layer, end-to-end anastomosis with separated long-term absorbable sutures, generous irrigation of the peritoneal cavity and subsequent layers with saline solution, closure by layers to avoid dead space, and avoidance of hematomas. No drains and no nasogastric tubes were used. Oral fluids were started the day after surgery and patients were discharged 48–72 h after the operation. Results The original diagnoses of the patients were: anorectal malformation (583), Hirschsprung’s disease (53), and others (13). 10 patients (1.5%) had complications: 6 had intestinal obstruction (5 due to small bowel adhesions, 1 had temporary delay of the function of the anastomosis due to a severe size discrepancy between proximal and distal stoma with a distal microcolon) and 4 incisional hernias. There were no anastomotic dehiscences or wound infection. There was no bleeding, no anastomotic stricture and no mortality. Conclusion Based on this experience we believe that colostomy closure can be performed with minimal morbidity provided a meticulous technique is observed. PMID:20714731

Accidental hypothermia (AH) is a complex and life threatening condition. Knowledge about epidemiology, rewarming treatments, complications and outcome is limited. This study was initiated to obtain data on causes, rewarming treatments and complications. A retrospective cohort study of all patients with a body temperature ≤ 35°C admitted to the Emergency Department (ED) of the VU university medical centre, Amsterdam, The Netherlands, between January 1, 2000 and August 31, 2008. A predefined set of epidemiological and clinical data was retrieved. Eighty-four patients were included (median age: 47 years). Categories of hypothermia included immersion (18), submersion (29) and exposure to cold (37); concomitant factors were intoxication (26), trauma (40) and homelessness (7). Temperature at admission in the ED was 31.6 ± 2.6°C (mean ± SD), lowest temperature 24.2°C. Fourteen different rewarming treatments were used resulting in a wide range of rewarming speeds. Seventy-nine complications occurred: pulmonary, renal and neurological complications in 20, 17 and 10 patients respectively. Seventeen patients had 2 or more late complications. Twenty-four patients (28.6%) died: 10 during rewarming and 14 after rewarming was completed. Prognosis was poor in older and colder patients and after indoor exposure and submersion. AH is a rare diagnosis in an inhomogeneous population, treated with a large variety of rewarming techniques. Most complications and death occurred late, after rewarming was completed. Because individual teams gain little clinical experiences, we suggest multiple centre data collection as a first step towards an evidence-based standard of care.

Atrial septum defect closure device in a beating heart, from the perspective of a researcher in artificial organs.

Tomizawa, Yasuko

2012-12-01

Transcatheter closure of atrial septum defect (ASD) with a closure device is increasing, but the history of clinical use of this procedure is still short, and the efficacy and long-term safety remain unproved. The total number of closure devices implanted throughout the world has not been counted accurately. Therefore, the probability of complications occurring after implantation is uncertain. Device-related complications that occur suddenly late after implantation are life-threatening, and quite often necessitate emergency surgical intervention. In Japanese medical journals, authors reporting closure devices have mentioned no complications and problems in their facilities. Detailed studies of device-related complications and device removal have not been reported in Japan. In fact, this literature search found an unexpectedly large number of reports of various adverse events from many overseas countries. When follow-up duration is short and the number of patients is small, the incidence of complications cannot be determined. Rare complications may emerge in a large series with a long observation period. Consequently, the actual number of incidents related to ASD closure devices is possibly several times higher than the number reported. Guidelines for long-term patient management for patients with an implanted closure device are necessary and post-marketing surveillance is appropriate. Development of a national database, a worldwide registration system, and continuous information disclosure will improve the quality of treatment. The devices currently available are not ideal in view of reports of late complications requiring urgent surgery and the need for life-long follow-up. An ideal device should be free from complications during life, and reliability is indispensable.

Since neurologic complications of childhood bacterial meningitis are encountered frequently despite antibiotic treatments, the purpose of this study was to analyze early neurologic complications and long-term sequelae of bacterial meningitis in children in a limited-resource country (Kosovo) This study uses a retrospective chart review of children treated for bacterial meningitis in two study periods: 277 treated during years 1997-2002 and 77 children treated during years 2009-2010. Of the 277 vs 77 children treated for bacterial meningitis, 60 (22%) vs 33 (43%) patients developed early neurologic complications, while there were 15 (5.4%) vs 2 (2.6%) deaths. The most frequent early neurologic complications were the following: subdural effusions (13 vs 29%), recurrent seizures (11 vs 8%), and hydrocephalus (3 vs 3%). The relative risk (95% confidence interval) for neurologic complications was the highest in infants (3.56 (2.17-5.92) vs 2.69 (1.62-4.59)) and in cases caused by Haemophilus influenzae 1.94 (1.09-3.18) vs Streptococcus pneumoniae 2.57(1.26-4.47). Long-term sequelae were observed in 10 vs 12% of children, predominantly in infants. The most frequent long-term sequelae were late seizures 9 vs 1%, neuropsychological impairment 1 vs 5%, and deafness 1 vs 3%. In both study periods, the most frequent early neurologic complications of childhood bacterial meningitis were subdural effusions. Long-term sequelae were observed in 10% of children, with late seizures, neuropsychological impairment, and deafness being the most common one. Age prior to 12 months was risk factor for both early neurologic complications and long-term sequelae of bacterial meningitis in children.

Variation in care within and across geographic areas remains poorly understood. The goal of this article was to examine whether physician social networks-as defined by shared patients-are associated with rates of complications after radical prostatectomy. In five cities, we constructed networks of physicians on the basis of their shared patients in 2004-2005 Surveillance, Epidemiology and End Results-Medicare data. From these networks, we identified subgroups of urologists who most frequently shared patients with one another. Among men with localized prostate cancer who underwent radical prostatectomy, we used multilevel analysis with generalized linear mixed-effect models to examine whether physician network structure-along with specific characteristics of the network subgroups-was associated with rates of 30-day and late urinary complications, and long-term incontinence after accounting for patient-level sociodemographic, clinical factors, and urologist patient volume. Networks included 2677 men in five cities who underwent radical prostatectomy. The unadjusted rate of 30-day surgical complications varied across network subgroups from an 18.8 percentage-point difference in the rate of complications across network subgroups in city 1 to a 26.9 percentage-point difference in city 5. Large differences in unadjusted rates of late urinary complications and long-term incontinence across subgroups were similarly found. Network subgroup characteristics-average urologist centrality and patient racial composition-were significantly associated with rates of surgical complications. Analysis of physician networks using Surveillance, Epidemiology and End Results-Medicare data provides insight into observed variation in rates of complications for localized prostate cancer. If validated, such approaches may be used to target future quality improvement interventions. Copyright © 2014 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

The report describes a patient with 45 per cent BSA burns who developed Legionnaire's disease 3 days after the acute injury. The diagnosis of this life-threatening complication was late because most of its signs and symptoms can be encountered in the burned patient. This delay could have been fatal to the patient and required the evacuation of the burn centre for disinfection.

This study aims to describe the incidence of infective complications, including tumour endoprosthesis infection, in a cohort of patients undergoing tumour endoprosthesis surgery in Victoria, Australia. This retrospective cohort study was performed over 15 years (January 1996-December 2010). 121 patients underwent tumour endoprosthesis surgery during the study period. Patients were followed for a median of 34 months (interquartile range [IQR] 17, 80). Overall, 34 patients (28%) experienced infective complications including: bacteraemia in 19 patients (16%) and tumour endoprosthesis infection in 17 (14%). The majority of patients with early and late acute infections (haematogenous) were managed with debridement and retention of the prosthesis in addition to biofilm-active antibiotics. Late chronic infections were predominantly managed by exchange of the prosthesis. The overall success rate of treatment was 71%. The success rate for debridement and retention was 75% compared with 67% for exchange procedures. There is a significant rate of infective complications following tumour endoprosthesis surgery including 14% of patients experiencing infection involving the tumour endoprosthesis. This study is the first to report on outcomes from debridement and retention of the prosthesis; which had comparable success rates to other treatment modalities. Crown Copyright © 2014.

Keegan, Beryl

2008-09-01

Radiofrequency cardiac ablation (RFCA) has become the treatment of choice for many cardiac arrhythmias that have not responded to medication. Complications of cardiac ablation include bleeding, thrombosis, pericardial tamponade, and stroke. Many complications are procedure specific, and several complications can be avoided with appropriate nursing care. Quality patient outcomes begin with competent nursing care. Therefore it is vital for a patient undergoing a percutaneous cardiac ablation procedure to receive supportive care and pre- and post-interventional patient education. This article discusses the nursing care of women undergoing RFCA.

Uterine torsion is a rare obstetrical complication whose diagnosis remains challenging. We report a case of 180 degrees dextrogyre torsion at 36(+5) weeks of gestation complicated by partial abruption and in utero fetal death. Emergency cesarean section was performed through an unintentional posterior hysterotomy. Literature reports a few similar cases. Vertical hysterotomy should be advised in this context avoiding incision on lateral sides associated with increased risk of vascular or ureteral injury. Copyright © 2013 Elsevier Masson SAS.

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

Passive avoidance is linked to impaired fear extinction in humans

Conventional wisdom dictates we must face our fears to conquer them. This idea is embodied in exposure-based treatments for anxiety disorders, where the intent of exposure is to reverse a history of avoidant behavior that is thought to fuel a patient’s irrational fears. We tested in humans the relationship between fear and avoidance by combining Pavlovian differential fear conditioning with a novel task for quantifying spontaneous passive avoidant behavior. During self-guided navigation in virtual reality following de novo fear conditioning, we observed participants keeping their distance from the feared object. At the individual level, passive avoidant behavior was highly associated with maladaptive fear expression (fear-potentiated startle) during late extinction training, indicating that extinction learning was impaired following a brief episode of avoidance. Avoidant behavior, however, was not related to initial acquired fear, raising doubt about a straightforward link between physiological fear and behavioral avoidance. We conclude that a deeper understanding of what motivates avoidance may offer a target for early intervention, before fears transition from the rational to the irrational. PMID:23427168

Facing the Music or Burying Our Heads in the Sand?: Adaptive Emotion Regulation in Midlife and Late Life

PubMed Central

Waldinger, Robert J.; Schulz, Marc S.

2011-01-01

Defenses that keep threatening information out of awareness are posited to reduce anxiety at the cost of longer-term dysfunction. By contrast, socioemotional selectivity theory suggests that preference for positively-valenced information is a late-life manifestation of adaptive emotion regulation. Using longitudinal data on 61 men, we examined links between emotion regulation indices informed by these distinct conceptualizations: defenses in earlier adulthood and selective memory for positively-valenced images in late-life. Use of avoidant defenses in midlife predicted poorer memory for positive, negative, and neutral images nearly 4 decades later. Late-life satisfaction was positively linked with midlife engaging defenses but negatively linked at the trend level with concurrent positive memory bias. PMID:21544264

We retrospectively analyzed infectious complications during tandem high-dose chemotherapy and autologous stem cell transplantation (HDCT/auto-SCT) in children and adolescents with high-risk or recurrent solid tumors. A total of 324 patients underwent their first HDCT/auto-SCT between October 2004 and September 2014, and 283 of them proceeded to their second HDCT/auto-SCT (a total of 607 HDCT/auto-SCTs). During the early transplant period of 607 HDCT/auto-SCTs (from the beginning of HDCT to day 30 post-transplant), bacteremia, urinary tract infection (UTI), respiratory virus infection, and varicella zoster virus (VZV) reactivation occurred in 7.1%, 2.3%, 13.0%, and 2.5% of HDCT/auto-SCTs, respectively. The early transplant period of the second HDCT/auto-SCT had infectious complications similar to the first HDCT/auto-SCT. During the late transplant period of HDCT/auto-SCT (from day 31 to 1 year post-transplant), bacteremia, UTI, and VZV reactivation occurred in 7.5%, 2.5%, and 3.9% of patients, respectively. Most infectious complications in the late transplant period occurred during the first 6 months post-transplant. There were no invasive fungal infections during the study period. Six patients died from infectious complications (4 from bacterial sepsis and 2 from respiratory virus infection). Our study suggests that infectious complications are similar following second and first HDCT/auto-SCT in children. PMID:27627440

Extensive cutaneous burns caused by alkylating chemical warfare agent sulfur mustard (SM) have been associated with the severe suppression of the immune system in humans. We aimed to study the association between late cutaneous and immunological complications of SM poisoning. Skin examination was performed on all SM-poisoned Iranian veterans in the province of Khorasan, Iran, who had significant clinical complications, and their SM intoxication was confirmed by toxicological analysis. Light microscopy was performed on eight skin biopsies. Blood cell counts, serum immunoglobulin and complement factor, as well as flow cytometric, analyses were performed on all the patients. The severity of cutaneous complications were classified into four grades and compared with hematological and immunological parameters, using Spearman's rank correlation test. Forty male subjects, confirmed with SM poisoning 16-20 years earlier, were studied. The main objective findings were hyperpigmentation (55%), dry skin (40%), multiple cherry angiomas (37.5%), atrophy (27.5%), and hypopigmentation (25%). Histopathologic findings were nonspecific and compatible with hyperpigmented old atrophic scars. Except for the hematocrit and C4 levels, hematological and immunological parameters revealed no significant correlation with the severity grades of cutaneous complications. Sulfur mustard is an alkylating agent with prolonged adverse effects on both the skin and the immune system. Although skin is a major transporting system for SM's systemic absorption, there is probably no correlation between the severity of late cutaneous and immunological complications of SM poisoning.

We started laparoscopic mini-gastric bypass (MGB) for the first time in India in February 2007 for its reported safety, efficacy, and easy reversibility. A retrospective review of prospectively maintained data of all 1,054 consecutive patients (342 men and 712 women) who underwent MGB at our institute from February 2007 to January 2013 was done. Mean age was 38.4 years, preoperative mean weight was 128.5 kg, mean BMI was 43.2 kg/m(2), mean operating time was 52 ± 18.5 min, and mean hospital stay was 2.5 ± 1.3 days. There were 49 (4.6%) early minor complications, 14 (1.3%) major complications, and 2 leaks (0.2%). In late complications, one patient had low albumin and one had excess weight loss; MGB was easily reversed in both (0.2%). Marginal ulcers were noted in five patients (0.6%) during follow-up for symptomatic dyspepsia, and anemia was the most frequent late complication occurring in 68 patients (7.6%). Patient satisfaction was high, and mean excess weight loss was 84, 91, 88, 86, 87, and 85% at years 1 to 6, respectively. This study confirms previous publications showing that MGB is quite safe, with a short hospital stay and low risk of complications. It results in effective and sustained weight loss with high resolution of comorbidities and complications that are easily managed.

Fermented soybeans (natto) have been reported to induce IgE-mediated, late-onset anaphylaxis without early-phase responses. However, the relevant allergens of natto allergy have never been identified. A 38-year-old man developed an anaphylactic reaction accompanied by flashing, generalized urticaria, conjunctival redness, and dyspnea 3 hours after ingestion of commercial cold Chinese noodles. He had avoided natto for the past year due to developing several anaphylactic reactions half a day after natto ingestion. The results of skin prick tests (SPTs) were strongly positive for natto and the soup of cold Chinese noodles. Furthermore, SPTs showed positive for poly (γ-glutamic acid) (PGA), which is a major constituent of natto mucilage, alone among all the ingredients of the cold Chinese noodle soup. Therefore, he was diagnosed with late-onset anaphylaxis to PGA contained in natto and the cold Chinese noodle soup. These results indicated that in the present case, the relevant allergen of late-onset anaphylaxis may have been PGA in all episodes and that the patient had been sensitized by PGA through natto ingestion. PGA is produced by Bacillus subtilis during fermentation and is a high-molecular, biodegradable polymer. The late onset is therefore, hypothesized to be due to a delayed absorption of PGA, as PGA biodegrades to peptides sufficiently small to be absorbed in the bowel. PGA has recently been applied to a wide range of fields such as foods, cosmetics, and medicine. Therefore, patients with late-onset anaphylaxis to PGA of natto should avoid not only natto but also other materials containing PGA.

Penile curvature is a common urological disease. Tunical plication for correction of penile curvature has been much popularized being simpler, adjustable to avoid overcorrection, less bleeding, and less postoperative erectile dysfunction. This study aims to assess the results of modified 16-dot plication technique for correction of congenital and acquired penile curvature and avoidance of knot-associated complications. Eighteen patients underwent correction of their penile curvature using the modified 16-dot plication technique between January 2014 and October 2015. Patients' pre and postoperative data were analyzed. The mean age of patients is 44 years old. Of the patients 15 who were available for follow-up, 8 patients had congenital penile curvature (CPC) and 7 had Peyronie's disease (PD). The angle of deviation ranged from 30° to 90°. Erectile function (EF) was assessed preoperative by IIEF score and duplex ultrasound. Postoperative follow-up at 3 and 6 months revealed straight erect penis in all patients. Longer follow-up at 1 to 2 years, 2 patients complained from slight recurrence of curve (<20°) and 2 patients complained of worsening of their erectile function. Penile shortening was noted by 6 patients. None of our patients stated any knot complication or bothersome, nor do hematomas, numbness, or painful erections. The modified 16-dot plication technique for correction if penile curvature is a safe and effective method. This modification allowed the knots to be tucked in the plicate tunical tissue avoiding knot-associated complications. More investigation on a large scale of patients or multicenter studies is recommended.

A dearth of laboratory tests to study actual human approach-avoidance behavior has complicated translational research on anxiety. The elevated plus-maze (EPM) is the gold standard to assess approach-avoidance behavior in rodents. Here, we translated the EPM to humans using mixed reality through a combination of virtual and real-world elements. In two validation studies, we observed participants' anxiety on a behavioral, physiological, and subjective level. Participants reported higher anxiety on open arms, avoided open arms, and showed an activation of endogenous stress systems. Participants' with high anxiety exhibited higher avoidance. Moreover, open arm avoidance was moderately predicted by participants' acrophobia and sensation seeking, with opposing influences. In a randomized, double blind, placebo controlled experiment, GABAergic stimulation decreased avoidance of open arms while alpha-2-adrenergic antagonism increased avoidance. These findings demonstrate cross-species validity of open arm avoidance as a translational measure of anxiety. We thus introduce the first ecologically valid assay to track actual human approach-avoidance behavior under laboratory conditions.

Retrospective review of prospective database. To investigate risk factors involved in the development of anterior cervical hematomas and determine any impact on patient outcomes. Postoperative (PO) hematomas after anterior cervical spine surgery require urgent recognition and treatment to avoid catastrophic patient morbidity or death. Current studies of PO hematomas are limited. Cervical spine surgical procedures performed on adults by the senior author at a single academic institution from 1995 to 2012 were evaluated. Demographic data, surgical history, operative data, complications, and neck disability index (NDI) scores were recorded prospectively. Cases complicated by PO hematoma were reviewed, and time until hematoma development and surgical evacuation were determined. Patients who developed a hematoma (HT group) were compared with those that did not (no-HT group) to identify risk factors. NDI outcomes were compared at early (<11 mo) and late (>11 mo) time points. There were 2375 anterior cervical spine surgical procedures performed with 17 occurrences (0.7%) of PO hematoma. In 11 patients (65%) the hematoma occurred within 24 hours PO, whereas 6 patients (35%) presented at an average of 6 days postoperatively. All underwent hematoma evacuation, with 2 patients (12%) requiring emergent cricothyroidotomy. Risk factors for hematoma were found to be (1) the presence of diffuse idiopathic skeletal hyperostosis (relative risk = 13.2, 95% confidence interval = 3.2-54.4), (2) presence of ossification of the posterior longitudinal ligament (relative risk = 6.8, 95% confidence interval = 2.3-20.6), (3) therapeutic heparin use (relative risk 148.8, 95% confidence interval = 91.3-242.5), (4) longer operative time, and (5) greater number of surgical levels. The occurrence of a PO hematoma was not found to have a significant impact on either early (HT: 30, no-HT: 28; P = 0.86) or late average NDI scores (HT: 28, no-HT 31; P = 0.76). With fast recognition and treatment, no long-term detriment from PO anterior cervical hematoma was found. We identified risk factors to be (1) presence of diffuse idiopathic skeletal hyperostosis, (2) presence of ossification of the posterior longitudinal ligament, (3) therapeutic heparin use, (4) longer operative time, and (5) greater number of surgical levels. 4.

Predicted Rate of Secondary Malignancies Following Adjuvant Proton Versus Photon Radiation Therapy for Thymoma.

Thymic malignancies are the most common tumors of the anterior mediastinum. The benefit of adjuvant radiation therapy for stage II disease remains controversial, and patients treated with adjuvant radiation therapy are at risk of late complications, including radiation-induced secondary malignant neoplasms (SMNs), that may reduce the overall benefit of treatment. We assess the risk of predicted SMNs following adjuvant proton radiation therapy compared with photon radiation therapy after resection of stage II thymic malignancies to determine whether proton therapy improves the risk-benefit ratio. Ten consecutive patients treated with double-scattered proton beam radiation therapy (DS-PBT) were prospectively enrolled in an institutional review board-approved proton registry study. All patients were treated with DS-PBT. Intensity modulated radiation therapy (IMRT) plans for comparison were generated. SMN risk was calculated based on organ equivalent dose. Patients had a median age of 65 years (range, 25-77 years), and 60% were men. All patients had stage II disease, and many had close or positive margins (60%). The median dose was 50.4 Gy (range, 50.4-54.0 Gy) in 1.8-Gy relative biological effectiveness daily fractions. No differences in target coverage were seen with DS-PBT compared with IMRT plans. Significant reductions were seen in mean and volumetric lung, heart, and esophageal doses with DS-PBT compared with IMRT plans (all P≤.01). Significant reductions in SMNs in the lung, breast, esophagus, skin, and stomach were seen with DS-PBT compared with IMRT. For patients with thymoma diagnosed at the median national age, 5 excess secondary malignancies per 100 patients would be avoided by treating them with protons instead of photons. Treatment with proton therapy can achieve comparable target coverage but significantly reduced doses to critical normal structures, which can lead to fewer predicted SMNs compared with IMRT. By decreasing expected late complications, proton therapy may improve the therapeutic ratio of adjuvant radiation therapy for patients with stage II thymic malignancies.

Neurologic complications after coronary artery bypass grafting remain a concern. Off-pump coronary artery bypass grafting is a surgical strategy proposed to decrease this risk. Use of an off-pump anaortic technique, which leaves the ascending aorta untouched, may result in further reductions. This systematic review of all published evidence compares neurologic complications after anaortic off-pump coronary artery bypass grafting versus that with aortic manipulation. PubMed and Embase were searched up to August 2008. Experts were contacted, and reference lists of retrieved articles were hand searched. The search process was not limited to English-language sources. Observational studies comparing standard off-pump coronary artery bypass grafting technique with anaortic technique were eligible for inclusion if they reported neurologic complications (stroke and transient ischemic attack). Meta-analysis was conducted to assess differences between groups with regard to neurologic complications. Electronic search identified 1428 abstracts, which resulted in retrieval and detailed review of 331 full-text articles. Eight observational studies reported neurologic complications in 5619 anaortic off-pump coronary artery bypass grafting cases and 5779 cases with aortic manipulation. Postsurgical neurologic complications were significantly lower in anaortic off-pump coronary artery bypass grafting cases (odds ratio, 0.46; 95% confidence interval, 0.29-0.72; I(2) = 0.8%; P = .0008). Avoidance of aortic manipulation during off-pump coronary artery bypass grafting decreases neurologic complications relative to standard technique in which the ascending aorta is manipulated. In patients at high risk for stroke or transient ischemic attack, we recommend avoidance of aortic manipulation during off-pump coronary artery bypass grafting.

2017-07-01

Despite overall improved outcomes with open reduction and internal fixation of acetabular fractures, posterior wall fractures show disproportionately poor results. The effect of weight bearing on outcomes of fracture management has been investigated in many lower extremity fractures, but evidence-based recommendations in posterior wall acetabular fractures are lacking. The authors systematically reviewed the current literature to determine if a difference in outcome exists between early and late postoperative weight-bearing protocols for surgically managed posterior wall acetabular fractures. PubMed and MEDLINE were searched for posterior wall acetabular fracture studies that included weight-bearing protocols and Merle d'Aubigné functional scores. Twelve studies were identified. Each study was classified as either early or late weight bearing. Early weight bearing was defined as full, unrestricted weight bearing at or before 12 weeks postoperatively. Late weight bearing was defined as restricted weight bearing for greater than 12 weeks postoperatively. The 2 categories were then compared by functional score using a 2-tailed t test and by complication rate using chi-square analysis. Six studies (152 fractures) were placed in the early weight-bearing category. Six studies (302 fractures) were placed in the late weight-bearing category. No significant difference in Merle d'Aubigné functional scores was found between the 2 groups. No difference was found regarding heterotopic ossification, avascular necrosis, superficial infections, total infections, or osteoarthritis. This systematic review found no difference in functional outcome scores or complication rates between early and late weight-bearing protocols for surgically treated posterior wall fractures.

Vena cava thrombectomy and primary repair after radical nephrectomy for renal cell carcinoma: single-center experience.

Helfand, Brian T; Smith, Norm D; Kozlowski, James M; Eskandari, Mark K

2011-01-01

Inferior vena cava (IVC) reconstruction for locally advanced renal cell carcinoma (RCC) includes resection with and without interposition grafting, patch graft, or primary repair. The proposed benefits of lateral venorrhaphy and primary repair are avoidance of foreign material, a more expeditious repair, and preservation of lower extremity venous outflow. A single-center retrospective review of 22 patients with RCC and IVC tumor thrombus treated with radical nephrectomy, lateral venorrhaphy, thrombectomy, and primary vena cava repair between July 2002 and June 2009 was carried out. Demographic data, diagnostic information, radiographic cross-sectional imaging, and procedural outcomes were examined. Among the 13 men and nine women, the mean age was 62.1 years (42-83); mean tumor size was 9.8 cm (3-17 cm), and 90% (n = 18) of the cases with RCC were identified pathologically as clear cell adenocarcinoma; on the basis of the classification system adopted by Neves, level I was for 50% (n = 11), level II for 32% (n = 7), level III for 9% (n = 2), and level IV for 9% (n = 2) of the patients. All patients underwent en bloc radical nephrectomy with tumor thrombus removal and primary IVC repair. Mean total operative time was 547.9 ± 138.5 minutes, whereas mean IVC cross-clamp time was 10.8 minutes (6-29 minutes). There were no intraoperative deaths or pulmonary embolism and all IVC margins were found to be pathologically negative. Postoperative complications included one pulmonary embolism, one exacerbation of chronic lymphedema, and two cases of new onset erectile dysfunction. Mean follow-up was 36.4 ± 23.2 months (6-92 months). There were no radiographic or clinically significant changes in mean IVC diameter during follow-up. Five late deaths (23%) occurred as a result of metastatic RCC over a mean period of 24 months (range, 12-48), but without any local recurrences. For advanced RCC with tumor thrombus extension into the IVC, lateral venorrhaphy and primary IVC repair avoids complicated caval reconstructions and results in high patency rates with a low local tumor recurrence rate.

2012-09-01

A number of people injured during the second world war harbour foreign bodies such as grenade splinters or bullets in some part of the body. Most of these metal fragments remain clinically silent. Some of them, however, may cause delayed complications. The purpose of this study was to determine the characteristics of delayed complications associated with foreign bodies after world war II injuries. 159 patients with retained foreign bodies after world war II injuries were retrospectively identified radiologically in our data bases in the time interval from 1997 to 2009. Diverse delayed complications secondary to the metal objects were diagnosed in 3 cases (2%): one patient with grenade splinter migration into the choledochal duct, one case with pseudotumoural tissue reaction, and one patient with late osteomyelitis. The time from injury to clinical presentation varied from 56 to 61 years. PubMed and Medline were screened for additional cases with delayed sequelae after foreign body acquisition during the 2nd world war. A 30 year search period from 1980 up to date was selected. 15 cases were identified here. Our study demonstrates that health consequences of the 2nd world war extend into the present time, and therefore physicians should be aware of the presence of hidden foreign bodies and their different possible late reactions.

2000-01-01

The purpose of this study was to compare on the basis of up to date papers currently applied methods of the percutaneous tracheostomy (PT). There are four main PT methods by: Ciaglia, Schachner, Griggs and Fantoni. In these methods a wire is introduced into the trachea serving as a guide for special forceps or series of dilatators of increasing diameter to dilate the wall and allow cannulation of the trachea. In the literature authors found a low incidence of complications after PT. Acute complications were documented in 6-18% and late complications in 1-3% of the patients. Follow-up showed no late obstructive complications at the level of stomia and very low (0.3-0.36%) mortality risk. Translaryngeal tracheostomy (TLT) by Fantoni ensures minimal risk of complications and tissue trauma. In the TLT method through a needle inserted in to the trachea a guide wire is retrogradely pushed out of the mouth and attached to special flexible tracheostomy tube by flexible plastic cone with pointed metal tip. This device is then pulled back through larynx and outwards across the trachea and neck wall by traction on the wire. TLT can also be used in infants and children and in difficult patients in whom other techniques are riskier Review of the literature suggests that the PT can be safe and also cost-effective for properly selected patients in intensive care and other hospital units.

To investigate the correlation between late rectal complications and rectal dose in cervix cancer patients treated with high-dose-rate intracavitary radiotherapy (HDR ICR) and to analyze factors reducing rectal complications. A total of 136 patients with cervix cancer who were treated with external beam radiotherapy (EBRT) and HDR ICR from 1995 to 1999 were retrospectively analyzed. Radiotherapy (RT) consisted of EBRT plus HDR ICR. The median EBRT dose was 50.4 Gy, and midline block was done after 30-50 Gy of EBRT. A total of six fractions of HDR ICR with 4 Gy fraction size each were applied twice per week to the A point. The rectal dose was calculated at the rectal reference point using the barium contrast criteria. In vivo measurement of the rectal dose was performed with thermoluminescent dosimeter (TLD) during HDR ICR. The median follow-up period was 26 months (range 6-60 months). A total of 16 patients (12%) experienced rectal bleeding, which occurred 4-33 months (median 11 months) after the completion of RT. The calculated rectal doses did not differ in patients with rectal bleeding and those without, but the measured rectal doses were higher in affected patients. The differences of the measured ICR fractional rectal dose, ICR total rectal dose, and total rectal biologically equivalent dose (BED) were statistically significant. When the measured ICR total rectal dose exceeded 16 Gy, the ratio of the measured rectal dose to A point dose was > 70%; when the measured rectal BED exceeded 110 Gy(3), a high possibility of late rectal complications could be found. In vivo dosimetry using TLD during HDR ICR was a good predictor of late rectal complications. Hence, if data from in vivo dosimetry shows any possibility of rectal bleeding, efforts should be made to reduce the rectal dose.

The reported rate of complications of reverse shoulder arthroplasty (RSA) seems to be higher than the complication rate of anatomical total shoulder arthroplasty. The reported overall complication rate of primary RSA is approximately 15%; when RSA is used in the revision setting, the complication rate may approach 40%. The most common complications of RSA include instability, infection, notching, loosening, nerve injury, acromial and scapular spine fractures, intra-operative fractures and component disengagement. Careful attention to implant design and surgical technique, including implantation of components in the correct version and height, selection of the best glenosphere-humeral bearing match, avoidance of impingement, and adequate management of the soft tissues will hopefully translate in a decreasing number of complications in the future.

Totally implantable access ports (TIAPs) are widely used in pediatric hematology-oncology patients. We investigated the incidence of complications, causes of TIAP removal, and risk factors for infection. We retrospectively analyzed the clinical, demographic, and surgical characteristics in 225 pediatric hematology-oncology patients implanted with 238 TIAPs between January 2004 and December 2005. Except for 20 patients lost to follow-up, the mean maintenance period was 724.8 +/- 500.6 days (range: 17-2,124). Mechanical complications occurred in seven patients (2.9%). The causes of TIAP removal were termination of use in 130 patients (59.6%), death from primary disease with TIAP in situ in 35 (14.7%), infection in 35 (14.7%), and obstruction in 4 (1.8%). Early infections occurred in nine patients at mean 37.77 +/- 16.44 days (range: 17-56). Late infections occurred in 26 patients at mean 334.5 +/- 257.82 days (range: 68-997). Univariate analysis showed that the risk factors of early infection were re-implantation (P = 0.022) and long operation time (P = 0.045). The risk factors of late infection were ANC <500/mm(3) (P = 0.011) and platelet count <50,000/mm(3) (P < 0.001). In multivariate analysis, re-implantation was a significant risk factor of early infection (P = 0.033, OR 4.528) and low platelet count (<50,000/mm(3)) was the independent risk factor for late infection (P = 0.005, OR 4.24). Correct procedure and careful use decreases the incidence of early infection and leads to the prevention of re-implantation. Initial thrombocytopenia was attributable to bone marrow suppression caused by hematologic malignancies or severe infection. Thus, this condition is of value in predicting late infection.

Coronary ostia obstruction after replacement of aortic valve prostesis

PubMed Central

2011-01-01

Aortic valve replacement (AVR) is the gold standard for the treatment of severe symptomatic aortic stenosis. Complications directly related to surgical procedure are relatively infrequent. Coronary ostial stenosis is, generally, referred as late complication. Anecdotal reports concern coronary ostial stenosis as acute complication. A unique fatal case of intraoperative, bilateral coronary ostial obstruction by prosthetic valve leading to an extensive myocardial infarction is reported. Surgeons must have a high level of vigilance regarding the occurrence of acute myocardial ischemia and sudden death soon after AVR. PMID:21810231

Loeys-Dietz syndrome (LDS) is an aggressive aortopathy with a proclivity for aortic aneurysm rupture and dissection at smaller diameters than other connective tissue disorders. We reviewed our surgical experience of children with LDS to validate our guidelines for prophylactic aortic root replacement (ARR). We reviewed all children (younger than 18 years) with a diagnosis of LDS who underwent ARR at our institution. The primary endpoint was mortality, and secondary endpoints included complications and the need for further interventions. Thirty-four children with LDS underwent ARR. Mean age at operation was 10 years, and 15 (44%) were female. Mean preoperative root diameter was 4 cm. Three children (9%) had composite ARR with a mechanical prosthesis, and 31 (91%) underwent valve-sparing ARR. Concomitant procedures included arch replacement in 2 (6%), aortic valve repair in 1 (3%), and patent foramen ovale closure in 16 (47%). There was no operative mortality. Two children (6%) required late replacement of the ascending aorta, 5 (15%) required arch replacement, 1 (3%) required mitral valve replacement, and 2 (6%) had coronary button aneurysms/pseudoaneurysms requiring repair. Three children required redo valve-sparing ARR after a Florida sleeve procedure, and 2 had progressive aortic insufficiency requiring aortic valve replacement after a valve-sparing procedure. There were 2 late deaths (6%). These data confirm the aggressive aortopathy of LDS. Valve-sparing ARR should be performed when feasible to avoid the risks of prostheses. Serial imaging of the arterial tree is critical, given the rate of subsequent intervention. Copyright © 2017 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

When the first suspected cases of neurologic disorders associated with the Zika virus were noticed in Brazil in late 2015, several studies had been conducted to understand the pathophysiology of the disease and its associated complications. In addition to its well-established association with microcephaly in neonates, the Zika virus infection has also been suggested to trigger other severe neurologic complications in adults, such as Guillain-Barré syndrome, radiculomyelitis, and meningoencephalitis. Hence, the Zika virus should be deemed a global threat that can cause devastating neurologic complications among individuals in all age ranges. The aim of this review was to further describe neuroimaging findings of Zika virus infection and associated neurologic complications found in adults. © 2018 by American Journal of Neuroradiology.

Infectious complications after hematopoietic stem cell transplantation: current status and future perspectives in Korea

Hematopoietic stem cell transplantation (HSCT) is a treatment for hematologic malignancies, immune deficiencies, or genetic diseases, ect. Recently, the number of HSCTs performed in Korea has increased and the outcomes have improved. However, infectious complications account for most of the morbidity and mortality after HSCT. Post-HSCT infectious complications are usually classified according to the time after HSCT: pre-engraftment, immediate post-engraftment, and late post-engraftment period. In addition, the types and risk factors of infectious complications differ according to the stem cell source, donor type, conditioning intensity, region, prophylaxis strategy, and comorbidities, such as graft-versushost disease and invasive fungal infection. In this review, we summarize infectious complications after HSCT, focusing on the Korean perspectives. PMID:29506345

The objective is to present the causes of late death in patients subjected to liver transplantation. A total of 209 patients were subjected to 223 liver transplantations (14 retransplantations). The computerized study protocol sheets were evaluated to determine the causes of late death (> 6 months after transplantation). Of the 209 patients, 30 had late death. Ductopenic rejection (chronic rejection) was the most common cause and it was observed in 10 patients. Time after transplantation at the moment of death of this group of patients varied from 11 to 57 months, with an average of 29 months. Seven patients died at the hospital admission of hepatic retransplantation. Other causes of late death were sepsis, lymphoproliferative disease, chronic renal insufficiency, and hepatic insufficiency. The most common cause of late death after liver transplantation is ductopenic rejection, followed by complications of retransplantation and sepsis. Death owing to ductopenic rejection may occur even many years after transplantation.

The majority of episodes of spontaneous posterior epistaxis treated with embolisation are idiopathic in nature. The angiographic findings are typically normal. Specific angiographic signs are rare and may include the following: a tumour blush, telangiectasia, aneurysm, and/or extravasation. Selective internal carotid artery (ICA) angiography may show rare causes of epistaxis, such as traumatic or mycotic aneurysms, which require different treatment approaches. Complete bilateral selective external and internal carotid angiograms are essential to evaluation. The images should be analysed for detection of central retinal blush in the external carotid artery (ECA) and anastomoses between the branches of the ECA and ICA.more » Monocular blindness and stroke are two of the most severe complications. Embolisation aims to decrease flow to the bleeding nasal mucosa while avoiding necrosis of the nasal skin and palate mucosa. Embolisation is routinely performed with a microcatheter positioned in the internal maxillary artery distal to the origin of the meningeal arteries. A guiding catheter should be placed in the proximal portion of the ECA to avoid vasospasm. Embolisation with microparticles is halted when the peripheral branches of the sphenopalatine artery are occluded. The use of coils is not recommended because recurrent epistaxis may occur due to proximal embolization; moreover, the option of repeat distal embolisation is lost. The success rate of embolisation therapy (accounting for late recurrence of bleeding) varies between 71 and 94 %. Results from endoscopic surgery are quite comparable. When epistaxis is refractory to nasal packing or endoscopic surgery, embolisation is the treatment of choice in some centres.« less

Hyperphagia is a frequent symptom in patients with Prader-Willi syndrome (PWS) and results in marked obesity with the risk of metabolic and cardiovascular complications. To investigate whether early diagnosis of PWS and strict dietary intervention prevents excessive weight gain in patients with PWS. A strict fat reduced and modified carbohydrate diet consisting of 10 kcal/ cm height was provided to nine patients (seven female, two male) diagnosed early with PWS (group A). Patients were prospectively followed at our center with follow-up visits every three months. Eight patients with late diagnosis of PWS served as controls (group B). Body mass index (BMI) SDS and height SDS were compared between these two groups over a ten-year period. At the age of two years height SDS and BMI SDS were significantly lower in group A (-2.9 vs -1.2, p <0.05, and BMI SDS -0.1 vs +1.8, p < 0.05). After ten years BMI SDS increased significantly to +1.2 SDS in group A, but was still significantly lower than in group B (BMI SDS +2.4), p <0.005. Patients without restrictive diet were significantly taller than patients on the diet (height SDS group A -2.8 vs group B -1.3, p < 0.05). Early dietary treatment starting at the second year of life and continued until the age of ten years is effective in avoiding excessive weight gain in patients with PWS, but results in shorter stature. Therefore growth hormone may be a useful additional treatment in these patients.

Prosthetic graft infection after vascular reconstruction is a rare but serious complication. We report a case of infection occurring late after implantation of an iliofemoral prosthetic vascular graft. The Staphylococcus aureus infection was revealed by vascular purpura localized on the right leg 7 years after implantation of a vascular prosthesis. This case illustrates an uncommonly late clinical manifestation presenting as an acute infection 7 years after the primary operation. In this situation, the presentation differs from early infection, which generally occurs within the first four postoperative months. Diagnosis and treatment remain a difficult challenge because prosthetic graft infection is a potentially life-threatening complication. Morbidity and mortality rates are high. Here we detail specific aspects of the clinical and radiological presentation. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

The aim of this study is to assess the value of early elective cesarean delivery for patients with gastroschisis in comparison with late spontaneous delivery. Analysis of infants with gastroschisis admitted between 1986 and 2006 at a tertiary care center was performed. The findings were analyzed statistically. Eighty-six patients were involved in the study. This included 15 patients who underwent emergency cesarean delivery (EM CD group) because of fetal distress and/or bowel ischemia. The remaining 71 patients born electively were stratified into 4 groups. The early elective cesarean delivery (ECD) group included 23 patients born by ECD before 36 weeks; late vaginal delivery (LVD) group included 23 patients who had LVD after 36 weeks; 24 patients had LCD after 36 weeks because of delayed diagnosis that resulted in late referral; and 1 patient had early spontaneous vaginal delivery (EVD group) before 36 weeks. The mean time to start oral feeding, incidence of complications, and primary closure were significantly better in the ECD group than in the LVD group. The duration of ventilation and the length of stay were shorter in ECD group, but the difference was not statistically significant. Elective cesarean delivery before 36 weeks allows earlier enteral feeding and is associated with less complications and higher incidence of primary closure (statistically significant).

Proton reirradiation for sarcoma has not been previously described. We hypothesized that this strategy would provide favorable toxicity and survival outcomes. Patients with soft tissue sarcoma in a previously-irradiated field were enrolled on a prospective trial of proton reirradiation. The primary endpoint was provider-reported acute toxicity. Secondary endpoints included late toxicities, local control, and overall survival. 23 patients underwent proton reirradiation. Median time between radiation courses was 40.7months (range 10-272). No grade 4-5 toxicities were observed. One patient (4%) experienced acute grade 3 dysphagia. Common grade 2 acute toxicities were fatigue (26%), anorexia (17%), and urinary incontinence (13%). There were two grade 3 late wound infections (10%) and one grade 3 late wound complication (5%). Grade 2 late complications included lymphedema (10%), fracture (5%), and fibrosis (5%). At a median follow-up of 36months, the 3-year cumulative incidence of local failure was 41% (95% CI [20-63%]). Median overall survival and progression-free survival were 44 and 29months, respectively. In extremity patients, amputation was spared in 7/10 (70%). Proton reirradiation of recurrent/secondary soft tissue sarcomas is well tolerated. While longer follow-up is needed, early survival outcomes in this high-risk population are encouraging.

In some centers, the presence of a senior general surgeon (SGS) is obligatory in every procedure, including appendectomy, while in others it is not. There is a relative paucity in the literature of reports comparing the outcomes of appendectomies performed by unsupervised general surgery residents (GSRs) with those performed in the presence of an SGS. To compare the outcomes of appendectomies performed by SGSs with those performed by GSRs. A retrospective analysis was performed of all patients 16 years or older operated on for assumed acute appendicitis between January 1, 2008, and December 31, 2015. The cohort study compared appendectomies performed by SGSs and GSRs in the general surgical department of a teaching hospital. The primary outcome measured was the postoperative early and late complication rates. Secondary outcomes included time from emergency department to operating room, length of surgery, surgical technique (open or laparoscopic), use of laparoscopic staplers, and overall duration of postoperative antibiotic treatment. Among 1649 appendectomy procedures (mean [SD] patient age, 33.7 [13.3] years; 612 female [37.1%]), 1101 were performed by SGSs and 548 by GSRs. Analysis demonstrated no significant difference between the SGS group and the GSR group in overall postoperative early and late complication rates, the use of imaging techniques, time from emergency department to operating room, percentage of complicated appendicitis, postoperative length of hospital stay, and overall duration of postoperative antibiotic treatment. However, length of surgery was significantly shorter in the SGS group than in the GSR group (mean [SD], 39.9 [20.9] vs 48.6 [20.2] minutes; P < .001). This study demonstrates that unsupervised surgical residents may safely perform appendectomies, with no difference in postoperative early and late complication rates compared with those performed in the presence of an SGS.

Complex head and neck reconstruction often mandates free tissue transfer to achieve the most optimal outcomes. Unfortunately, such challenging cases are not without risks of complications, the most dreaded of which is loss of the free flap. Aside from loss of the free flap, there are several other potential complications that can result following head and neck reconstruction. Certain complications are avoided with careful planning, others require significant revisions and in certain cases another free flap. This article presents the experience managing a series of unique complications following free flap head and neck reconstruction. Published by Elsevier Inc.

The root displacement into the maxillary sinus could be a complication of oral surgery in the upper jaw. In these cases, the root removal is needed in order to avoid the occurrence of sinus pathologies. Piezosurgery techniques could assure a safer management of such complications, because of the clear surgical visibility and the selective ability of cut. The aim of this article is to present a case of oral surgery complication (root displacement in the right maxillary sinus), in which piezosurgery technique helped for a correct and safe clinical management, allowing to reduce the soft tissue damage.

Fear of hypoglycaemia in parents of young children with type 1 diabetes: a systematic review.

Many children with type 1 diabetes have poor glycaemic control. Since the Diabetes Control and Complications Trial (DCCT) showed that tighter control reduces complication rates, there has been more emphasis on intensified insulin therapy. We know that patients and families are afraid of hypoglycaemia. We hypothesised that fear of hypoglycaemia might take precedence over concern about long-term complications, and that behaviour to avoid hypoglycaemia might be at the cost of poorer control, and aimed to evaluate the effectiveness of any interventions designed to prevent that. The objective of this review was to systematically review studies concerning the extent and consequences of fear of hypoglycaemia in parents of children under 12 years of age with type 1 diabetes, and interventions to reduce it. MEDLINE, EMBASE, PsycINFO, The Cochrane Library, Web of Science, meeting abstracts of EASD, ADA and Diabetes UK, Current Controlled Trials, ClinicalTrials.gov, UK CRN, scrutiny of bibliographies of retrieved papers and contact with experts in the field.Inclusions: Relevant studies of any design of parents of children under 12 years of age with Type 1 diabetes were included. The key outcomes were the extent and impact of fear, hypoglycaemia avoidance behaviour in parents due to parental fear of hypoglycaemia in their children, the effect on diabetes control, and the impact of interventions to reduce this fear and hypoglycaemia avoidance behaviour. Eight articles from six studies met the inclusion criteria. All were cross sectional studies and most were of good quality. Parental fear of hypoglycaemia, anxiety and depression were reported to be common. There was a paucity of evidence on behaviour to avoid hypoglycaemia, but there were some suggestions that higher than desirable blood glucose levels might be permitted in order to avoid hypoglycaemia. No studies reporting interventions to reduce parental fear of hypoglycaemia were found. The evidence base was limited. Parents of children with Type 1 diabetes reported considerable parental fear of hypoglycaemia, affecting both parental health and quality of life. There is some suggestion that hypoglycaemia avoidance behaviours by parents might adversely affect glycaemic control. Trials of interventions to reduce parental anxiety and hypoglycaemia avoidance behaviour are needed. We suggest that there should be a trial of structured education for parents of young children with Type 1 diabetes.

This retrospective study evaluated the effects of early extraction of immature lower third molar on preventing complications, particularly nerve injury following lower third molar removal. Patients were grouped according to age and radiographic results: group A (518 patients, ≤23 years, immature teeth with apical foramen not closed); group B (532 patients, >23 years, mature teeth with closed apical foramen). Group A included 230 males and 288 females (average age 17 years). In group A, 808 lower mandibular third molars were extracted bilaterally in 290 and unilaterally in 228 patients; the incidence of complications was 2.48% (20/808) (all were temporary), the incidence of nerve injury was 0%. Group B included 250 males and 282 females (average age 39 years). In group B, 810 lower third molars were extracted bilaterally in 278 and unilaterally in 254 patients; the incidence of complications was 10% (81/810), the incidence of nerve injury was 1.6% (13/810). All complications were temporary, except two removals of permanent inferior alveolar nerve numbness (>6 months). In this study, early removal of the lower third molar was effective in avoiding some postoperative complications, especially nerve injury. Early extraction of lower third molar in youngsters is recommended following a team consultation. Copyright © 2012 International Association of Oral and Maxillofacial Surgeons.

Late onset paraplegia is a rare complication of spinal tuberculosis. Disease reactivation and cord compression by internal gibbus are the common causes for neurological deficit. We report a patient with post-tubercular kyphotic deformity in whom the late onset paraplegia is caused by ossified ligamentum flavum above the level of kyphotic deformity. The deficit was attributable to the ossified ligamentum flavum and she recovered completely following posterior decompression and instrumented posterolateral fusion. To the best of our knowledge, this is the first report of this unusual cause of late onset paraplegia.

[Some peculiarities in the manifestation of oxidative stress and current status of antioxidant system in adolescents of different age groups with obesity, complicated by insulin resistance and without it].

PubMed

Kuleshova, D K; Davydov, V V

2014-01-01

The study has shown that neuroendocrine obesity in adolescents is associated with the formation of oxidative stress which is more pronounced in early than in late puberty. Obesity with concomitant insulin resistance increases manifestations of oxidative stress accompanied by a compensatory increase in the activity of catabolic enzymes and reduced capacity of the defense antioxidant system in late puberty. These alterations may be caused by age-related changes in hormonal secretion under conditions of insulin resistance in late puberty.

Laparoscopic simple prostatectomy has been proposed to treat large glands. To date groups have investigated the feasibility and perioperative results of laparoscopic simple prostatectomy but to our knowledge no study has focused on its complications and functional results at longer followup. We investigated complications and functional results in patients with a large prostate who were treated with laparoscopic simple prostatectomy and had at least 1 year of followup. From our prospectively maintained database we extracted data on 78 patients treated with laparoscopic simple prostatectomy at our institution who had at least 1 year of reported followup. Demographics, perioperative results, early and late complications, and functional results were evaluated. Followup was planned at 1, 3, 6 and 12 months, and every 6 months thereafter. Mean followup was 30 months. Grade III complications were recorded in 2 cases and late complications were reported in 4 (5%). Statistically significant differences were observed in the International Prostate Symptom Score, the International Prostate Symptom Score quality of life index and maximum urine flow when comparing preoperative and postoperative results. No significant differences were recorded in maximum urine flow or the International Prostate Symptom Score quality of life index during followup. Results suggest that laparoscopic simple prostatectomy is safe and effective even after a significant period, as indicated by the low complication rate and positive, stable functional results found during followup. In our opinion laparoscopic simple prostatectomy can be offered to patients as a valid treatment option for a large prostate at advanced laparoscopic centers.

Complications of diabetes comprise the leading cause of death in Mexico. We aimed to describe the characteristics of management and achievement of therapeutic targets in Mexican patients with diabetes mellitus. We analyzed data from 2642 Mexican patients with type 1 (T1D, n=203, 7.7%) and type 2 diabetes (T2D, n=2439, 92.3%) included in the third wave of the International Diabetes Management Practices Study. Of T2D patients, 63% were on oral glucose-lowering drugs (OGLD) exclusively (mostly metformin), 11% on insulin, 22% on OGLD plus insulin, and 4% on diet and exercise exclusively. T2D patients on insulin were more likely to be trained on diabetes, but they were older, had worse control, longer disease duration and more chronic complications than patients on OGLD only. Glycated hemoglobin (HbA1c) <7% was achieved by 21% and 37% of T1D and T2D patients, respectively. Only 5% of T1D and 3% of T2D attained the composite target of HbA1c <7%, blood pressure <130/80 mmHg and low-density lipoprotein cholesterol <100 mg/dl. T1D patients had less macrovascular but more microvascular complications, compared with T2D patients. Late complications increased with disease duration, so that about 80% of patients after 20 years of diagnosis have at least one late complication. Reaching the target HbA1c <7% was associated with a reduced number of microvascular but not with less macrovascular complications. A great proportion of these Mexican patients with diabetes did not reach therapeutic targets. Insulin was used mostly in complicated cases with advanced disease. Copyright © 2011 SEEN.

Social-psychological profiles of identity styles: attitudinal and social-cognitive correlates in late adolescence.

PubMed

Soenens, Bart; Duriez, Bart; Goossens, Luc

2005-02-01

This study examined the relationships between three identity styles (i.e. the information style, the normative style, and the diffuse/avoidant style) and a number of social-cognitive and attitudinal variables (including empathy, prejudice, and conservatism). Discriminant analysis on a sample of late adolescents (N=393) led to the conclusion that two classes of variables differentiate between the three identity styles. Maladaptive coping strategies and, to a lesser extent, low empathy distinguished mainly between the information style and the normative style on the one hand and the diffuse/avoidant style on the other hand. Need for closure and measures of prejudice and conservatism differentiated primarily between the normative style and the two other styles. These two classes of variables can be related to two basic dimensions in current theory on adolescents' identity styles, that is, active vs. superficial processing of information and adherence to traditional opinions vs. openmindedness.

Dimensionality of posttraumatic stress disorder symptoms in children exposed to disaster: results from confirmatory factor analyses.

PubMed

Anthony, J L; Lonigan, C J; Hecht, S A

1999-05-01

Factor analytic studies of trauma victims' posttraumatic stress disorder (PTSD) have offered conflicting hypotheses about how to conceptualize PTSD into symptom categories. The present study used confirmatory factor analyses of self-reported PTSD symptomatology from 5,664 child and adolescent victims of Hurricane Hugo to compare 10 models of PTSD dimensionality. PTSD was best represented by a 2nd-order PTSD factor that manifests in 3 symptom clusters (Intrusion/Active Avoidance, Numbing/Passive Avoidance, and Arousal). This model was cross-validated on 3 age groups (late childhood, early adolescence, and late adolescence), and results indicated factorial invariance across groups. PTSD symptoms varied in relative centrality to the underlying dimensions of PTSD, which differed in their relations with anxiety and degree of traumatic exposure. Implications for classification criteria and an empirically supported theory of PTSD are discussed.

2013-01-01

Endoscopic endonasal sinus surgery represents the overall accepted type of surgical treatment for chronic rhinosinusitis. Notwithstanding raised and still evolving quality standards, surgeons performing routine endoscopic interventions are faced with minor complications in 5% and major complications in 0.5–1%. A comprehensive review on all minor and major complications of endoscopic surgery of the paranasal sinuses and also on the anterior skull base is presented listing the actual scientific literature. The pathogenesis, signs and symptoms of each complication are reviewed and therapeutic regimens are discussed in detail relating to actual publication references. Potential medico-legal aspects are explicated and recent algorithms of avoidance are mentioned taking into account options in surgical training and education. PMID:24403974

External ureteroneocystostomy in renal transplantation.

Cos, L R; Light, J A; Stutzman, R E

1985-10-01

The urologic complications of 184 consecutive renal transplants (68 living-related and 116 cadaveric) performed at Walter Reed Army Medical Center are reviewed. An anterior extravesical technique modified from Witzel, Sampson, and Lich was used to reimplant the ureter. Urologic complications occurred in 11 patients (6%): urine leak (4), obstruction (3), stricture (3), and total ureteral necrosis (1). These complications occurred in the first 115 patients; no complications have been documented in the last 69 patients. The several advantages of extravesical ureteroneocystostomy include: less operative time, avoidance of a separate cystotomy, virtually no hematuria, ability to use short ureters, no need for splints or stents, shortened Foley catheter drainage, and no interference with native ureteral function. Complications are few and become uncommon with practice.

Haemothorax after mediastinoscopy: a word of caution.

2012-01-01

Mediastinoscopy is used for the staging of lung cancer and for the diagnosis of mediastinal lesions. It is a valuable diagnostic tool but, in a few cases, it could result in major complications. We describe a simple technique to avoid the development of a major complication--massive haemothorax--after a mediastinoscopy, which should be applied in cases of inadvertent injury of the pleura during the procedure.

Understanding the history of stream erosion and changes in channel morphology is important for managing and restoring unstable streams. One of the significant challenges in this type of research is establishing accurate dating of late Holocene and historic alluvium. Here we evaluate the potential of using 14C dating and amino acid racemization (AAR) to date large terrestrial gastropod shells that are often preserved within alluvial sediments. Many terrestrial gastropods incorporate old carbon from limestone or other carbonate rocks into their shells and therefore are unsuitable for radiocarbon dating. Recent studies, however, have shown that some taxa avoid this ‘limestone problem’ and can yield reliable 14C ages. In this study, we measured the 14C activity of specimens for the genera Mesodon, Ventridens, and Allogona collected live and from alluvial sequences dated independently by dendrochronology, 14C dating of wood, and/or 137Cs analyses. Mesodon zaletus contained old carbon in similar concentrations (up to ~ 30%) found in previous studies of other large taxa and should be avoided for 14C dating when possible. In contrast, shells of Ventridens ligera and Allogona profunda showed minimal limestone effects and therefore may be suitable for dating late Holocene alluvium. These results highlight the importance of taxonomic identification of gastropod taxa prior to their use for 14C dating and demonstrate that shell fragments that are not identifiable should be avoided. We also measured d/l ratios (n = 17) of aspartic and glutamic acid from eight different taxa of terrestrial gastropods recovered from four late Holocene and historic stratigraphic sequences. Average d/l ratios of aspartic and glutamic acid from historic sediments < 300 years old are lower in shells from younger stratigraphic units, indicating that AAR can be used to differentiate between multiple historic stratigraphic units.

Rectosigmoid stump washout as an alternative to permanent mucous fistula in patients undergoing subtotal colectomy for ulcerative colitis in emergency settings.

Restorative proctocolectomy with ileopouch-anal anastomosis (IPAA) is the treatment of choice for intractable or complicated ulcerative colitis(UC). Elderly patients often present with acute colitis requiring emergent subtotal colectomy(SC). Frail patients are at risk of developing septic complications related to the closed rectosigmoidal stump, often requiring formation of a second stoma to be reversed at the time of completion proctectomy. This carries nuisance to such exhausted patients. We propose a simple and inexpensive trick to avoid the need for creating a mucous fistula. IPAA was performed as a 3-stage procedure in emergency settings. The rectosigmoidal stump was closed and placed subcutaneously; skin was closed over it. After SC, if patients showed signs of stump-related pelvic sepsis, a lavage of the rectal stump with povidone iodine solution and with saline was carried out as a rescue treatment aiming to avoid the need of opening the rectal stump to drain sepsis. Thirty-five patients underwent SC for UC between 1987 and 2012. The skin was closed over the closed stump in the 20. Seven patients out of these 20 experienced early stump-related septic complication. In five cases, we were able to avoid opening of the rectal stump, and a second stoma was unnecessary. After opening the closed stump in the remaining ones, a prompt improving of symptoms was observed. Rectal washout was well tolerated and avoided a second stoma in five out of seven patients, with better quality of life and body perception after IPAA surgery. This is relevant when dealing with geriatric patients, needing to completely recover before undergoing completion proctectomy.

Urgent surgery for complicated colonic diverticula.

Funariu, Gheorghe; Binţinţan, Vasile; Seicean, Radu

2006-03-01

The AIM of this retrospective study was to evaluate the emergency surgical treatment of life-threatening complications of colonic diverticula. In the last 11 years, 22 of 101 patients with colonic diverticula (22.1%) underwent urgent surgery for acute complications: perforated gangrenous diverticulitis with generalized peritonitis (n=8) or pericolic abscess (n=8), acute bowel obstruction (n=4) and severe diverticular bleeding (n=2). In all patients with diffuse peritonitis or acute obstruction the indication for surgery was decided on clinical basis and the complicated diverticula were recognized only intra-operatively. Emergency surgical strategy differed according to the type of complication and the biologic condition of the patient: segmental colectomy and primary anastomosis for diverticular perforation (n=4), colonic stenosis (n=3) or diverticular bleeding (n=2); Hartmann resection with late reconnecting anastomosis in patients with diverticular perforation (n=5) or colonic obstruction (n=1); diverticulectomy with peritoneal drainage (n=2) and colostomy and drainage followed by secondary colectomy (n=5) for diverticular perforations in patients with poor general condition. Only one patient (4.5%) died post-operatively of multiple organ failure from generalized peritonitis. There was no anastomotic leakage in patients with primary anastomosis. Six patients (27.2%) developed wound infection. Hospital stay ranged between 11 and 60 days, significantly longer in cases with two-stage operations. Primary colectomy with immediate or delayed anastomosis is the best surgical procedure for acute divericular complications in patients with good biologic status. Two-stage operations such as colostomy and drainage coupled with late colectomy remain the viable alternative in patients with advanced disease and critical biologic condition.

The aim of this study was to address the inconsistency regarding the operative treatment of Rockwood type III acromioclavicular joint separation. We compared results after single- and double TightRope ® reduction with results after acromioclavicular transfixation via K-wires only and additional ligament augmentation in acute acromioclavicular (AC) joint separations graded Rockwood type III, and hypothesized that the TightRope ® technique leads to better clinical and radiological results. We conducted a retrospective clinical cohort study and included 42 consecutive patients (mean age 43 years [24-66]) diagnosed and operatively treated between 2004 and 2012 (mean follow-up was 54.6 months [15-118]). Specific shoulder scores as well as scores reflecting the patients' overall mental and physical health status were used. Radiological evaluation was also performed. The SF12 test revealed comparability between all subgroups. Specific shoulder tests and a visual analogue scale demonstrated comparable results. Radiographic measurements showed a significant reduction in the AC distance and CC distance after surgery in all subgroups. The early complication rate was 9.5% for all patients, while late complications occurred in 14.3% of all cases. Compared to the established methods, the operative TightRope ® procedures represent a safe alternative in Rockwood III injuries. All investigated techniques predominantly led to good and excellent clinical results in acute Rockwood type III AC joint instabilities. Avoidance of material removal and shorter hospital stays appear to speak in favour for the TightRope ® technique. IV. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Understanding Tobacco Use Onset Among African Americans.

Compared to the majority of non-Hispanic white ("white") cigarette smokers, many African American smokers demonstrate a later age of initiation. The goal of the present study was to examine African American late-onset smoking (ie, regular smoking beginning at age 18 or later) and determine whether late-onset (vs. early-onset) smoking is protective in terms of quit rates and health outcomes. We used data from the National Survey of Midlife Development in the United States (MIDUS) because the wide age range of participants (20-75 at baseline) allowed the examination of smoking cessation and mortality incidence across the lifespan. Consistent with previous research, results indicated a later average age of smoking onset among African Americans, compared to whites. Disentangling effects of race from age-of-onset, we found that the cessation rate among late-onset African American smokers was 33%, whereas rates for early-onset African American smokers and early- and late-onset white smokers ranged from 52% to 57%. Finally, results showed that among white, low-socioeconomic status (SES) smokers, the hazard rate for mortality was greater among early- versus late-onset smokers; in contrast, among African American smokers (both low- and high-SES) hazard rates for mortality did not significantly differ among early- versus late-onset smokers. Although late (vs. early) smoking onset may be protective for whites, the present results suggest that late-onset may not be similarly protective for African Americans. Tobacco programs and regulatory policies focused on prevention should expand their perspective to include later ages of initiation, in order to avoid widening tobacco-related health disparities. This study indicates that late-onset smoking is not only the norm among African American adult smokers, but that late- versus early-onset smoking (ie, delaying onset) does not appear to afford any benefits for African Americans in terms of cessation or mortality. These results suggest that prevention and intervention efforts need to consider individual groups (not just overall averages) and that tobacco control efforts need to be targeted beyond the teenage years. Tobacco programs and regulatory policies focused on prevention should expand their perspective to include later ages of initiation, to avoid widening tobacco-related health disparities. © The Author 2016.

Introduction: Compared to the majority of non-Hispanic white (“white”) cigarette smokers, many African American smokers demonstrate a later age of initiation.

A review of literature on the neurodevelopmental origins of schizophemia is presented, with particular attention to neurodevelopmental processes in late-onset schizophemia. Definitions of the term “neurodevelopmental” as used in schizophernia literature are first provided. Next, evidence for the developmental origins of the neuropathology in schizophemia is reviewed. This evidence includes studies of the associations between schizophemia and neurodevelopmental brain aberrations, minor physical anomalies, obstetric complications, prenatal viral exposure, childhood neuromotor abnormalities, and pandysmaturation. A brief discussion of the predominant theories about the neurodevelopmental origins of schizophemia is then provided. The concept and nature of “late-onset schizophenia ”is next defined and discussed. Finally, the neurodevelopmental literature is discussed in relation to the phenomenon of late-onset schizophemia. Based on this review, we conclude that there exists a strong likelihood that late-onset schizophrenia involves neurodevelopmental processes. PMID:21584112

Reconstruction after total maxillectomy with extensive orbital floor defects poses a significant challenge for the reconstruction. The aim of this study is to present the outcomes of orbital floor reconstruction using tensor fascia lata slings after total maxillectomy and to compare these results to orbital floor reconstruction using alloplastic implants. This was a retrospective analysis of 19 consecutive patients who underwent tumor resection with orbital floor removal for malignancies. Reconstructions were performed using either tensor fascia lata slings (Group A) or alloplastic implants (Group B). The early and late postoperative outcomes such as wound infection, plate exposure, ectropion, diplopia, and enophthalmos, were analyzed and compared between the two groups. Patients in group A had significantly less wound complication than in group B (p < 0.05). In group A, there were no early or late wound complications after the operation. However, in group B, five patients had infection, the plate was exposed in eight of fourteen patients, and three patients had enophthalmos. Eight patients in group B underwent reoperation to correct their complications. Reconstruction of the orbital floor with a tensor fascia lata sling offers reliable support to the globe and prevents the ophthalmic complications associated with loss of orbital support.

To evaluate the efficacy of hypofractionated radiotherapy for canine nasal tumours, including the improvement in clinical signs, rate of complications and assessment of prognostic factors. Medical records of 38 dogs with malignant nasal tumours were reviewed, and those treated with a weekly schedule of hypofractionated radiotherapy were included in the study. Acute and late side effects were defined as complications noted either within 1 month or after 6 months of irradiation, respectively. Progression-free interval and overall survival were calculated using the Kaplan-Meier method. Log-rank test and Cox proportional hazard model were also performed. Clinical signs improved in 30 of 36 dogs. Acute complications were seen in 28 of 36 dogs and were considered manageable. Late complications were observed in 17 of 30 dogs that survived 6 months or longer, but severe side effects were not observed. The median progression-free interval and overall survival was 245 days (95% CI: 127-512 days) and 512 days (95% CI: 203-820 days), respectively. Age, breed and presence of dyspnoea were negatively correlated with overall survival. These results suggest that hypofractionated radiotherapy could be a viable option for the treatment of nasal tumours in dogs that are not candidates for conventional multi-fractionated radiotherapy. © 2013 British Small Animal Veterinary Association.

The treatment choice for post-intubation tracheal stenosis (PITS) in patients for whom surgery is not initially feasible is bronchoscopic silicone stenting. A new silicone stent, called the Natural stent (N stent), was investigated for its clinical efficacy and safety in patients with PITS. A retrospective review was conducted of 32 patients with PITS who underwent N stenting between November 2001 and December 2006 and were followed for at least 12 months. Airway dilatation with combined modalities such as Nd:YAG laser, ballooning or bougienage was followed by N stent insertion. After intervention, all patients had symptomatic and spirometric improvement without immediate complications. Removal of the stent without re-stenosis was successful in 38% of the patients at a median time of 7 months after insertion. The stent could not be removed or needed reinsertion in 31% of patients, and 16% of patients underwent surgery after initial stabilization by stenting. Late complications were stent migration (34%), mucostasis (31%), granulation tissue formation (38%) and re-stenosis (40%). All patients tolerated the management of complications during a median follow up of 22 months. Bronchoscopic N stenting is an effective treatment for patients with PITS in whom surgery is not feasible on initial presentation. Further stent development is necessary to reduce the late complication rate.

OBJECTIVE  The study estimated cost of illness from the provider's perspective for diabetic patients who received treatment during the fiscal year 2008 at Waritchaphum Hospital, a 30-bed public district hospital in Sakhon Nakhon province in northeastern Thailand. METHODS  This retrospective, prevalence-based cost-of-illness study looked at 475 randomly selected diabetic patients, identified by the World Health Organization's International Classification of Diseases, 10th revision, codes E10-E14. Data were collected from the hospital financial records and medical records of each participant and were analysed with a stepwise multiple regression. KEY FINDINGS  The study found that the average public treatment cost per patient per year was US$94.71 at 2008 prices. Drug cost was the highest cost component (25% of total cost), followed by inpatient cost (24%) and outpatient visit cost (17%). A cost forecasting model showed that length of stay, hospitalization, visits to the provincial hospital, duration of disease and presence of diabetic complications (e.g. diabetic foot complications and nephropathy) were the significant predictor variables (adjusted R(2) = 0.689). CONCLUSIONS  According to the fitted model, avoiding nephropathy and foot complications would save US$19 386 and US$39 134 respectively per year. However, these savings are missed savings for the study year and the study hospital only and not projected savings, as that would depend on the number of diabetic patients managed in the year, the ratio of complicated to non-complicated cases and effectiveness of the prevention programmes. Nonetheless, given the high avoidable cost associated with complications of diabetes, healthcare providers in Thailand should focus on initiatives that delay the progression of complications in diabetic patients. © 2011 The Authors.

Hemorrhoidectomy is considered the most efficient method to treat hemorrhoids of III and IV grades. The aim of this study was to compare conventional diathermy hemorrhoidectomy and radiofrequency hemorrhoidectomy based on a large series of patients. Between June 2001 and June 2014, 1000 patients have been treated with radiofrequency hemorrhoidectomy (group A) and 500 patients have been treated with diathermy (group B) as a day-case procedure. Operating time, postoperative pain score, hospital stay, early and late postoperative complications, wound healing time and time to return to normal activities were assessed. The mean follow-up was seven years. The mean operating time for radiofrequency hemorrhoidectomy was shorter than diathermy but not significantly. Patients treated with radiofrequency had significantly less postoperative pain (measured on a Visual Analogue Scale; P=0.001), a shorter wound healing time, less time off work and postoperative complications (P=0.001) than patients who had diathermy. Neither wound healing nor mean hospital stay (day-case surgery) was significantly different. Radiofrequency hemorrhoidectomyis a valid alternative to the conventional diathermy technique, due to the reduction of operative time, postoperative pain, early and late complication rate.

Stereotactic radiosurgery (SRS) is an established modality for the treatment of vestibular schwannomas (VSs). However, its long-term vascular complications have not been well-studied. Among the 360 patients who underwent SRS for VS in our institution and lived for >5 years thereafter, we identified only 1 patient who exhibited complication due to a late-onset aneurysm; thus, the incidence was roughly estimated to be 0.3%. The patient was a 78-year-old man who had undergone SRS for a right VS, and presented with right peripheral facial palsy 19 years later. Radiographic examinations revealed a distal anterior inferior cerebellar artery (AICA) fusiform aneurysm, which was embedded in the tumor, and progressively enlarged over 17 months. Although the right AICA perfused a large area of the cerebellum, the aneurysm was successfully treated with AICA trapping, in conjunction with an occipital artery-AICA bypass. Distal AICA pseudoaneurysm formation is a rare, but potentially severe, late complication after SRS for VS. This is the first case that successfully treated this pathology with AICA trapping with occipital artery-AICA bypass. Copyright © 2018. Published by Elsevier Inc.

Acute vulvar pain in a lady with post circumcision inclusion cyst of the vulva containing stones: a case report.

Despite global eradication efforts, female genital cutting is still deep routed practice in some parts of Asia and East Africa. The crude and unscientific natures of the practice lead to many complications. Epidermoid inclusion cysts of the vulva are one of the late complications of female genital cutting and typically present as painless cystic swellings. But clinical presentation as 'stone' containing, hard vulvar mass is reported only once in the literature and presentation with acute vulvar pain has never been documented. A 21 yrs old, Ethiopian, unmarried, lady presented with sever acute vulvar pain, discharge, and a stony hard vulvar swelling 13 years after type-III female genital cutting (infibulation). Surgical excision of the cyst, which contained two 'stones' inside it, and defibulation were done. Histopathology confirmed calcified, keratinizing epidermoid inclusion cyst of the vulva. Clinicians, in areas where female genital cutting is prevalent, should be aware of such unusual late vulvar complication of the practice which might be misdiagnosed for other solid vulvar swellings and be familiar with the appropriate management.

Optical Coherence Tomography for Quantitative Assessment of Microstructural and Microvascular Alterations in Late Oral Radiation Toxicity

NASA Astrophysics Data System (ADS)

Davoudi, Bahar

More than half of head-and-neck cancer patients undergo radiotherapy at some point during their treatment. Even though the use of conformed therapeutic beams has increased radiation dose localization to the tumor, resulting in more normal tissue sparing, still, in many head-and-neck cancer patients, the healthy tissue of the oral cavity still receives a sizeable amount of radiation. This causes acute and / or late complications in these patients. The latter occur as late as several months or even years after the completion of treatment and are typically associated with severe symptoms. Currently, the clinical method for diagnosing these complications is visual examination of the oral tissue surface. However, it has been well established that such complications originate in subsurface oral tissue layers including its microvasculature. Therefore, to better understand the mechanism of these complications and to be able to diagnose them earlier, there exists a need for subsurface monitoring of the irradiated oral tissue. Histology has been used as such a tool for research purposes; however, its use in clinical diagnosis is limited due to its invasive and hazardous nature. Therefore, in this thesis, I propose to use optical coherence tomography (OCT) as a subsurface, micron-scale resolution optical imaging tool that can provide images of oral tissue subsurface layers down to a depth of 1-2 mm (structural OCT), as well as images demonstrating vessel morphology (speckle variance OCT) and blood flow information (Doppler OCT). This thesis explains the development of an OCT setup and an oral probe to acquire images in-vivo. Moreover, it introduces a software-based quantification platform for extracting specific biologically-meaningful metrics from the structural and vascular OCT images. It then describes the application of the developed imaging and quantification platform in a feasibility clinical study that was performed on 15 late oral radiation toxicity patients and 5 age-matched healthy volunteers. The results of this clinical study show that: 1) the value of the developed metrics (such as epithelium to lamina propria thickness, vessel diameter, and blood velocity) is significantly different between the two cohorts; 2) radiation-induced abnormalities in structural OCT images are primarily observed in the regions where the total radiation dose exceeded ˜50 Gy. The results of this study demonstrate the promising ability of the developed OCT imaging and quantification platform to highlight biologically meaningful differences between late oral radiation toxicity patients and healthy volunteers in the structural and vascular images. This methodology may also be used in prognostic studies to monitor the efficacy of the medication prescribed to late oral radiation toxicity patients.

Introduction Creation of gastrointestinal stomas is a common colorectal procedure associated with early or late complications, some of which demand advanced technical skills and expertise for optimal management. Case History A 63-year-old male underwent a defunctioning loop colostomy for locally advanced rectal cancer with liver metastasis. Three months later, he had developed a skinfold over his stoma that resulted in a horizontal skin crease traversing through the stoma, causing the stoma to ‘sink’ leading to obliteration of the stomal opening. This scenario led to ineffective attachment of a stoma appliance, resulting in painful peristomal ulcers. After excision of the anterior abdominal wall, assessment of colostomy opening was carried out, followed by closure of the subcutaneous tissues and drain fixation. An elevated colostomy with an adequate functional opening was seen after wound closure. The patient made an uneventful recovery and was discharged home. After 3 weeks, he had a fully opened, normally functioning colostomy and peristomal ulcers were almost healed. Conclusions This case highlights the challenges of stoma management, its related risks, avoidance of delay in chemotherapy, a patient wish for early return to work, and the novel approach we adopted to deal with these issues.

Survival rates after allogeneic hematopoietic cell transplantation (HCT) for Fanconi anemia (FA) have increased dramatically since 2000. However, the use of autologous stem cell gene therapy, whereby the patient's own blood stem cells are modified to express the wild-type gene product, could potentially avoid the early and late complications of allogeneic HCT. Over the last decades, gene therapy has experienced a high degree of optimism interrupted by periods of diminished expectation. Optimism stems from recent examples of successful gene correction in several congenital immunodeficiencies, whereas diminished expectations come from the realization that gene therapy will not be free of side effects. The goal of the 1st International Fanconi Anemia Gene Therapy Working Group Meeting was to determine the optimal strategy for moving stem cell gene therapy into clinical trials for individuals with FA. To this end, key investigators examined vector design, transduction method, criteria for large-scale clinical-grade vector manufacture, hematopoietic cell preparation, and eligibility criteria for FA patients most likely to benefit. The report summarizes the roadmap for the development of gene therapy for FA. PMID:21540837

EHLERS-DANLOS SYNDROMES (EDS): A heterogeneous group of hereditary conditions having in common a molecular anomaly of the extracellular matrix comprise EDS. Clinical and genetic features are used for classification and in some cases the molecular anomaly can be demonstrated. Six main types are recognized and termed classic, hypermobile, vascular, cyphoscoliotic, arthrochalasic and dermatosparaxis. Skin and joint signs predominate, visceral disease is fortunately rare. The skin is hyperelastic and heals poorly. Joint involvement may lead to luxations and early-onset osteoarthritis causing chronic pain. The prognosis is severe in certain types such as vascular EDS where arterial ruptures may be life-threatening. Patients with cyphoscoliotic EDS may become bedridden due to the scoliosis and muscular hypotrophy. Minor forms as well as rapidly fatal major forms often go undiagnosed or are identified late after a complication which could have been avoided. A multidisciplinary approach is needed as certain interventions, technical procedures or explorations may have catastrophic consequences. The creation of an EDS association would be helpful in federating specialists and allow global management. The gravity of certain forms, the poorly understood epidemiology and the progressive nature of EDS point to the need for a national registry.

Half forehead reconstruction with a single rotational scalp flap for dermatofibrosarcoma protuberans treatment.

Dermatofibrosarcoma protuberans (DFSP) is a soft tissue neoplasm of intermediate to low-grade malignancy. Although metastasis rarely occurs, DFSP has a locally aggressive behavior with a high recurrence rate. In the head and neck area, resection involving a wide margin of healthy tissue can be difficult because of functional and cosmetic considerations. We describe a novel reconstructive method for half forehead defects with an innovative single local wide scalp flap following excision of DFSP with a 3 cm margin of healthy tissue. Two patients underwent wide resection of forehead DFSP and reconstruction with a single rotational scalp flap. The scalp flap blood supply was provided from three main vessels: the superficial temporal artery, occipital artery and posterior auricular artery. No early or late complications were observed in either patient with no local recurrence after 18 months of follow-up. The donor area could be closed primarily in both cases and the flaps survived completely. This innovative technique allowed a radical excision of forehead DFSP with sufficient healthy margins, thus potentially decreasing tumor recurrence rate. Reconstruction was achieved avoiding microsurgery, skin expanders and large skin grafts. Moreover, all main reconstructive criteria, such as functional and cosmetic tissue characteristics, were completely fulfilled.

Nowadays cataract extraction combined intraocular lens (IOL) implantation has become the conventional treatment for cataract. Numbers of IOL exchange after cataract extraction combined IOL implantation have been increasing in recent years. As a non-routine surgery, IOL exchange is normally combined with other surgeries and accompanied by some complications to various extents. Is IOL exchange necessary for all abnomal IOLs? Can IOL exchange be avoided? How to avoid IOL exchange? The purpose of this article is to stress the importance of indication of IOL exchange and how to avoid IOL exchange.

The older orthopaedic patient: general considerations.

PubMed

Potter, Jane F

2004-08-01

People older than 65 years are more likely to need elective and emergent orthopaedic surgery compared with younger persons. They also experience significant benefits. Although age-related changes increase the risk of perioperative complications, understanding those changes allows prevention or at least early recognition and treatment when problems arise. Because of comorbidities, older persons take more medications that need to be managed in the perioperative period. Care could be simplified if patients were to bring their medications to the preoperative evaluation. Central nervous system sensitivity to certain pain medications (meperidine and propoxyphene) means that these drugs are best avoided as good alternatives exist (morphine and oxycodone). Adverse reactions to drugs are an important cause of acute confusion (delirium) that often complicates orthopaedic care. Early mobilization after surgery, avoiding certain drugs, avoiding restraints (including Foley catheters), attending to hydration, promoting normal sleep, compensating for sensory disorders, and stimulating daytime activities can prevent delirium. Patients with dementia are more likely to have delirium develop and, like many older people, will present special challenges in communication and decision making. Including family members in discussions may be helpful in ensuring truly informed consent.

To investigate the safety and feasibility of laparoscopic extraperitoneal sigmoid colostomy. Thirty-six patients with low rectal cancer undergoing laproscopic abdominoperineal resection from July 2011 to July 2012 were prospectively enrolled in the study and randomly divided into extraperitoneal colostomy group(EPC, n=18) and internal peritoneal colostomy group(IPC, n=18). Follow-up period was 4-16 (median, 7) months and postoperative complications were compared between two groups. One case in EPC group was converted to IPC because of poor blood supply of the proximal sigmoid, who was eliminated from the subsequent analysis. Compared with the IPC group, the surgery time was longer in EPC group [(25.3±8.5) min vs. (14.7±6.4) min], while the difference was not statistically significant(P>0.05). Each group had 1 case of stoma ischemia, who both received the colostomy reconstructive surgery. The incidence of stoma edema was significantly higher in EPC group[35.3%(6/17) vs. 0, P<0.05). The early postoperative complications rate did not significantly different between the two groups[58.8%(10/17) vs. 27.8%(5/18), P>0.05]. The late postoperative complications rate was 22.2%(4/18) in IPC group, including 1 case of stoma prolapse, 1 case of stoma stenosis and 2 cases of parastomal hernia. No later postoperative complication occurred in EPC group. Extraperitoneal sigmoid colostomy is an easy and safe procedure with lower late complications as compared to internal peritoneal sigmoid colostomy.

We report the case of a 45-year-old male patient who developed an acute peptic ulcer perforation of the tubal stomach on the second postoperative day after oesophagectomy. The patient underwent emergency surgery (perforation was closed with a Graham patch) followed by treatment in intensive care, and was finally discharged on the 19th postoperative day. Gastric pull-up is a surgical technique that is widely used to re-establish the continuity of the gastrointestinal tract after oesophagectomy. Various early and late complications of reconstruction with the tubal stomach are well-known, such as gastric necrosis, gastritis, gastric ulcer, as well as benign and malignant tumors. The precise etiology of gastric tube ulceration is not known yet, however, it can develop not only in the late, but also in the early postoperative period, as well.

To compare the risk of complications between initial nonoperative treatment and appendectomy of uncomplicated (simple) appendicitis in children. Systematic literature search. Eligible for inclusion were both and randomized controlled trials and cohort studies including children in which the outcome of nonoperative treatment of uncomplicated appendicitis was reported with a minimum follow-up period of one year. Two authors extracted data independently and assessed quality. Primary outcome parameter was the percentage of children experiencing complications. Secondary outcomes were early failures, recurrent appendicitis and appendectomies, for all indications and on request. Five of the 2051 articles screened were eligible for inclusion, including 147 children (nonoperative treatment) and 173 children (appendectomy) with one year follow-up. Percentage of children experiencing complications ranged from 0 to 13% versus 0-17% for nonoperative and appendectomy, respectively. Nonoperative treatment avoided an appendectomy in 62-81% of the children after one year follow-up. The evidence base for initial nonoperative treatment of acute uncomplicated appendicitis in children is by far insufficient. It suggests that the percentage of patients experiencing complications in the initial nonoperative treatment group is comparable to the appendectomy group, and it may avoid an appendectomy in the large majority of children after one year follow-up.

BACKGROUND Long-term adhesion-related complications and incisional hernias after abdominal surgery are common and costly. There are few data on the risk of these complications after different abdominal operations. STUDY DESIGN We identified Medicare beneficiaries who underwent endovascular repair of an abdominal aortic aneurysm from 2001–2008 who presumably are not at risk for laparotomy-related complications. We identified all laparoscopic and open operations involving the abdomen, pelvis, or retroperitoneum and categorized them into 5 groups according to invasiveness. We then identified laparotomy-related complications for up to 5 years after the index operation and compared these with the baseline rate of complications in a control group of patients who did not undergo an abdominal operation. RESULTS We studied 85,663 patients, 7,513 (8.8%) of which underwent a laparotomy, including 2,783 major abdominal operations, 709 minor abdominal operations, 963 ventral hernia repairs, 493 retroperitoneal/pelvic operations, and 2,565 laparoscopic operations. Mean age was 76.7 years and 82.0% were male. Major abdominal operations carried the highest risk for adhesion-related complications (14.3% and 25.0% at 2 and 5 years compared with 4.0% and 7.8% for the control group; p < 0.001) and incisional hernias (7.8% and 12.0% compared with 0.6% and 1.2% for the control group; p < 0.001). Laparoscopic operations (4.6% and 10.7% for adhesions, 1.9% and 3.2% for incisional hernias) carried the lowest risk. CONCLUSIONS Late-onset laparotomy-related complications are frequent and their risk extends through 5 years beyond the perioperative period. With the advancement and expansion of laparoscopic techniques and its attendant lower risk for long-term complications, these results can alter the risk-to-benefit profile of various types of abdominal operations and can also strengthen the rationale for additional development of laparoscopic approaches to abdominal operations.

One of the earliest but often unaddressed signs of facial aging is volume loss in the temple. Treatment of the area can produce satisfying results for both patient and practitioner. Safe injection requires explicit knowledge of the anatomy to avoid complications related to the multitude of vessels that course throughout the region at various depths. The authors aim to detail the anatomy of the area and provide a safe and easy-to-follow method for injection. The authors review the relevant anatomy of the temporal region and its application to cosmetic filler injections. The authors describe an easy-to-follow approach for a safe and effective injection window based on numerous anatomical studies. Injection in this area is not without risk, including potential blindness. The authors review the potential complications and their treatments. Hollowing of the temple is an early sign of aging that, when corrected, can lead to significant patient and practitioner satisfaction. Proper anatomically knowledge is required to avoid potentially severe complications. In this study, the authors present a reliable technique to safely and effectively augment this often undertreated area of the aging face.

Safe percutaneous suprapubic catheterisation.

Goyal, N K; Goel, A; Sankhwar, S N

2012-11-01

We describe our technique of percutaneous suprapubic catheter insertion with special reference to steps that help to avoid common complications of haematuria and catheter misplacement. The procedure is performed using a stainless steel reusable trocar under local infiltrative anaesthesia, usually at the bedside. After clinical confirmation of a full bladder, the trocar is advanced into the bladder through a skin incision. Once the bladder is entered, the obturator is removed and the assistant inserts a Foley catheter followed by rapid balloon inflation. Slight traction is applied to the catheter for about five minutes. Patients with previous lower abdominal surgery, an inadequately distended bladder or acute pelvic trauma do not undergo suprapubic catheterisation using this method. The procedure was performed in 72 men (mean age: 42.4 years, range: 18-78 years) with urinary retention with a palpable bladder. The average duration of the procedure was less than five minutes. No complications were noted in any of the patients. Trocar suprapubic catheter insertion is a safe and effective bedside procedure for emergency bladder drainage and can be performed by resident surgeons. The common complications associated with the procedure can be avoided with a few careful steps.

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

When we learn to drive, our driving instructor tells us how to check the side mirror and turn your head to check the blind spot before changing lanes. He tells us how to stop at stop signs, how to drive in slippery conditions, the safe stopping distances, and these all make our driving safe. Similarly, when we learn PCI, our mentors teach us to seat the guiding catheter co-axially, to wire the vessel safely, to deliver balloon and stents over the wire, to watch the pressure of the guiding, in order that we perform PCI safely and evade complications. In retrograde CTO PCI, there is no such published teaching. Also many individual mentors have not had the wide experience to see all the possible complications of retrograde CTO PCI and, therefore, may not be able to warn their apprentice. As the number of retrograde procedures increase worldwide, there is a corresponding increase in catastrophic complications, many of which, we as experts, can see are easily avoidable. To breach this gap in knowledge, this article describes 12 commonly met inherent traps in retrograde CTO PCI. They are inherent because by arranging our equipment in the manner to perform retrograde CTO PCI, these complications are either induced directly or happen easily. We hope this work will enhance safety of retrograde CTO PCI and avoid many catastrophic complications for our readers and operators. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

The shortage of deceased donor liver grafts led to the use of living donor liver transplant (LDLT). Patients who undergo LDLT have a higher risk of complications than those who undergo deceased donor liver transplantation (LT). Interventional radiology has acquired a key role in every LT program by treating the majority of vascular and non-vascular post-transplant complications, improving graft and patient survival and avoiding, in the majority of cases, surgical revision and/or re-transplant. The aim of this paper is to review indications, diagnostic modalities, technical considerations, achievements and potential complications of interventional radiology procedures after LDLT.

Clinical interventions for late-life anxious depression.

PubMed

Diefenbach, Gretchen J; Goethe, John

2006-01-01

Anxiety symptoms are frequently present in patients with late-life depression. The designation "anxious depression" has been used to describe major depressive disorder (MDD) accompanied by clinically significant but subsyndromal anxiety symptoms. MDD may also present comorbid with diagnosable anxiety disorders, although this presentation is less common in late life. Diagnosis of anxious depression in the elderly is complicated by several factors (eg, their tendency to experience and report psychiatric symptoms as somatic illness) and is associated with a more severe clinical presentation, increased risk for suicidal ideation, increased disability, and poorer prognosis. Standard pharmacotherapy for depression may be sufficient but for many patients must be modified or augmented. Psychosocial interventions may also be an important component in the treatment of these patients, although no specific psychosocial treatments have been developed for late-life anxious depression.

The present study examines a more fine-grained analysis of anxiety-related and depression-related outcomes amongst a sample of treatment completers who were assigned to complicated grief treatment (CGT) (n = 35) or interpersonal psychotherapy (IPT) (n = 34) in a previously reported randomized controlled trial. We examined effects of antidepressant use and measures of anxiety and depression, focusing especially on guilt related to the death or deceased and grief-related avoidance in order to further understand the differential effectiveness of CGT and IPT amongst participants who received the full course of treatment. Analyses showed that CGT produced greater reductions in anxiety and depressive symptoms including negative thoughts about the future and grief-related avoidance. CGT's advantage over IPT in lowering depression was most pronounced amongst those not taking antidepressants. Our results further elucidate CGT effects and support the idea that CG and major depressive disorder are distinct conditions. Targeted treatment for complicated grief (CG) produces benefits in associated mood and anxiety symptoms and CG symptoms. Amongst patients with CG, interpersonal psychotherapy seems relatively ineffective in ameliorating depressive symptoms. Grief-related depressive symptoms may not respond to standard treatments unless CG symptoms are also addressed. Reducing grief-related symptoms, such as anxieties about the future, guilt related to the death or deceased and avoidance of reminders of the loss may be important aspects in reducing CG.

The aim of this study is to evaluate the effectiveness and safety of percutaneously placed totally implantable venous-access ports (TIVAPs) of the forearm. Between January 2006 and October 2008, peripheral TIVAPs were implanted in 763 consecutive patients by ultrasound and fluoroscopic guidance. All catheters were implanted under local anesthesia and were tunneled subcutaneously. Indication, technical success, and complications were retrospectively analyzed according to Society of Interventional Radiology (SIR) criteria. Presence of antibiotic prophylaxis, periprocedurally administered drugs (e.g., sedation), and laboratory results at the time of implantation were analyzed. Maintenance during the service interval was evaluated. In total, 327,499 catheter-days weremore » analyzed. Technical success rate was 99.3%. Reasons for initial failure of implantation were either unexpected thrombosis of the subclavian vein, expanding tumor mass of the mediastinum, or failure of peripheral venous access due to fragile vessels. Mean follow-up was 430 days. There were 115 complications observed (15.1%, 0.03 per 100 catheter-days), of which 33 (4.3%) were classified as early (within 30 days from implantation) and 82 (10.7%) as late. Catheter-related venous thrombosis was found in 65 (8.5%) of 763 (0.02 per 100 catheter-days) TIVAPs. Infections were observed in 41 (5.4%) of 763 (0.01 per 100 catheter-days) devices. Other complications observed included dislocation of the catheter tip (0.8%), occlusion (0.1%), or rupture (0.1%) of the port catheter. Dislocated catheters were corrected during a second interventional procedure. In conclusion, implantation of percutaneously placed peripheral TIVAPs shows a high technical success rate and low risk of early complications when ultrasound and fluoroscopic guidance are used. Late complications are observed three times as often as early complications.« less

It was done according to the rules of the Franco-Italian glossary, presented at the 7th ESTRO meeting, held in The Hague on September 1988. They were ranked by organ sites and by degrees of gravity. The analysis was done on the total number of complications and they were scored at the highest reached grade of gravity. Seventy one complications were found in 55 patients; they were studied by patient, degree of severity, time of onset, organ system and grade, time of onset and grade, time of onset and organ sites, stage and RT doses and brachytherapy volumes. The importance of the study of complications is stressed, particularly when treatment combines external RT and brachytherapy; some guidelines are given to avoid severe complications.

Percutaneous endoscopic gastrostomy (PEG) has been used for providing enteral access to patients who require long-term enteral nutrition for years. Although generally considered safe, PEG tube placement can be associated with many immediate and delayed complications. Buried bumper syndrome (BBS) is one of the uncommon and late complications of percutaneous endoscopic gastrostomy (PEG) placement. It occurs when the internal bumper of the PEG tube erodes into the gastric wall and lodges itself between the gastric wall and skin. This can lead to a variety of additional complications such as wound infection, peritonitis, and necrotizing fasciitis. We present here a case of buried bumper syndrome which caused extensive necrosis of the anterior abdominal wall.

To assess liver remnant volume regeneration and maintenance, and complications in the long-time follow-up of donors after living donor liver transplantation using CT and MRI. 47 donors with a mean age of 33.5 years who donated liver tissue for transplantation and who were available for follow-up imaging were included in this retrospective study. Contrast-enhanced CT and MR studies were acquired for routine follow-up. Two observers evaluated pre- and postoperative images regarding anatomy and pathological findings. Volumes were manually measured on contrast-enhanced images in the portal venous phase, and potential postoperative complications were documented. Pre- and postoperative liver volumes were compared for evaluating liver remnant regeneration. 47 preoperative and 89 follow-up studies covered a period of 22.4 months (range: 1 - 84). After right liver lobe (RLL) donation, the mean liver remnant volume was 522.0 ml (± 144.0; 36.1 %; n = 18), after left lateral section (LLS) donation 1,121.7 ml (± 212.8; 79.9 %; n = 24), and after left liver lobe (LLL) donation 1,181.5 ml (± 279.5; 72.0 %; n = 5). Twelve months after donation, the liver remnant volume were 87.3 % (RLL; ± 11.8; n = 11), 95.0 % (LS; ± 11.6; n = 18), and 80.1 % (LLL; ± 2.0; n = 2 LLL) of the preoperative total liver volume. Rapid initial regeneration and maintenance at 80 % of the preoperative liver volume were observed over the total follow-up period.  Minor postoperative complications were found early in 4 patients. No severe or late complications or mortality occurred. Rapid regeneration of liver remnant volumes in all donors and volume maintenance over the long-term follow-up period of up to 84 months without severe or late complications are important observations for assessing the safety of LDLT donors. Liver remnant volumes of LDLT donors rapidly regenerated after donation and volumes were maintained over the long-term follow-up period of up to 84 months without severe or late complications. © Georg Thieme Verlag KG Stuttgart · New York.

Adolescents and young adults disproportionately abuse 3,4-methylenedioxymethamphetamine (MDMA; ‘Ecstasy’); however, since most MDMA research has concentrated on adults, the effects of MDMA on the developing brain remain obscure. Therefore, we evaluated place conditioning to MDMA (or saline) during late adolescence and assessed anxiety-like behavior and monoamine levels during abstinence. Rats were conditioned to associate 5 or 10 mg/kg MDMA or saline with contextual cues over 4 twice-daily sessions. Five days after conditioning, anxiety-like behavior was examined with the open field test and brain tissue was collected to assess serotonin (5-hydroxytryptamine, 5-HT) and its metabolite 5-hydroxyindoleacetic acid (5-HIAA) in the dorsal raphe, amygdala, and hippocampus by high-pressure liquid chromatography (HPLC). In a separate group of rats, anxiety-like and avoidant behaviors were measured using the light–dark box test under similar experimental conditions. MDMA conditioning caused a place aversion at 10, but not at 5, mg/kg, as well as increased anxiety-like behavior in the open field and avoidant behavior in light–dark box test at the same dose. Additionally, 10 mg/kg MDMA decreased 5-HT in the dorsal raphe, increased 5-HT and 5-HIAA in the amygdala, and did not alter levels in the hippocampus. Overall, we show that repeated high (10 mg/kg), but not low (5 mg/kg), dose MDMA during late adolescence in rats increases anxiety-like and avoidant behaviors, accompanied by region-specific alterations in 5-HT levels during abstinence. These results suggest that MDMA causes a region-specific dysregulation of the serotonin system during adolescence that may contribute to maladaptive behavior. PMID:24121061

An avoidable hospitalization (AH) is a condition that could have been prevented through effective treatment in outpatient care. Diabetes is often referred to as an ambulatory care-sensitive condition, and its associated hospitalizations are often referred to as avoidable hospitalizations. There are limited data on avoidable hospitalizations for individuals with diabetes in Taiwan. We used the National Health Interview Survey (NHIS) dataset to obtain diabetes-related avoidable hospitalizations for subjects aged above 12 years. We included data from 20,826 subjects who had completed the interview between 2004 and 2005. Data were collected from a total of 15,574 people, who had agreed to link their health information to the Taiwan National Health Insurance Research Database, including basic demographic variables, inpatient or outpatient medical events, admission date, discharge date, and diagnosis. The 1005 individuals who self-reported having diabetes or had at least 1 hospitalization or 2 physician service claims for diabetes mellitus with an ICD-9 diagnosis of 250 were included in the analysis. We divided those with diagnosis of diabetes into two groups: never hospitalized and hospitalized. The never hospitalized group served as the control group. We further identified hospitalized subjects with long-term complications due to diabetes (PQI-3) that included ICD-CM codes 250.4-250.9. The mean ages of patients with diabetes-related long-term complications in the hospitalized and never hospitalized groups were 65 years and 58 years, respectively (p-value<0.01). More than half (52%) of the patients with diabetes-related long-term complications had a body mass index (BMI) lower than 24. The hospitalized group also had lower educational status compared with that of patients in the never hospitalized group (equal to or lower than elementary school, 63% vs. 50%; junior high school, 23% vs. 14%; equal or higher than senior high school, 14% vs. 36%). Furthermore, hospitalized patients tended to have lower household monthly income, were unmarried, and did not have private medical insurance. There were no significance differences in ethnic composition between the groups. Interestingly, patients with frequent retinal examination, and those with lower body mass index had higher frequency of avoidable hospitalization (p<0.01). We found that the following factors were associated with a higher frequency of avoidable hospitalization among patients with type 2 diabetes: elderly, male, lower body mass index, lower household income, non-exercise, higher disease comorbidity, and frequent retinal examination.

Bumble-bee learning selects for both early and long flowering in food-deceptive plants

Most rewardless orchids engage in generalized food-deception, exhibiting floral traits typical of rewarding species and exploiting the instinctive foraging of pollinators. Generalized food-deceptive (GFD) orchids compete poorly with rewarding species for pollinator services, which may be overcome by flowering early in the growing season when relatively more pollinators are naive and fewer competing plant species are flowering, and/or flowering for extended periods to enhance the chance of pollinator visits. We tested these hypotheses by manipulating flowering time and duration in a natural population of Calypso bulbosa and quantifying pollinator visitation based on pollen removal. Both early and long flowering increased bumble-bee visitation compared with late and brief flowering, respectively. To identify the cause of reduced visitation during late flowering, we tested whether negative experience with C. bulbosa (avoidance learning) and positive experience with a rewarding species, Arctostaphylos uva-ursi, (associative learning) by captive bumble-bees could reduce C. bulbosa's competitiveness. Avoidance learning explained the higher visitation of early- compared with late-flowering C. bulbosa. The resulting pollinator-mediated selection for early flowering may commonly affect GFD orchids, explaining their tendency to flower earlier than rewarding orchids. For dissimilar deceptive and rewarding sympatric species, associative learning may additionally favour early flowering by GFD species. PMID:22090384

Chronic radiation-induced dermatitis: challenges and solutions.

PubMed

Spałek, Mateusz

2016-01-01

Chronic radiation dermatitis is a late side effect of skin irradiation, which may deteriorate patients' quality of life. There is a lack of precise data about its incidence; however, several risk factors may predispose to the development of this condition. It includes radiotherapy dose, fractionation, technique, concurrent systemic therapy, comorbidities, and personal and genetic factors. Chronic radiation dermatitis is mostly caused by the imbalance of proinflammatory and profibrotic cytokines. Clinical manifestation includes changes in skin appearance, wounds, ulcerations, necrosis, fibrosis, and secondary cancers. The most severe complication of irradiation is extensive radiation-induced fibrosis (RIF). RIF can manifest in many ways, such as skin induration and retraction, lymphedema or restriction of joint motion. Diagnosis of chronic radiation dermatitis is usually made by clinical examination. In case of unclear clinical manifestation, a biopsy and histopathological examination are recommended to exclude secondary malignancy. The most effective prophylaxis of chronic radiation dermatitis is the use of proper radiation therapy techniques to avoid unnecessary irradiation of healthy skin. Treatment of chronic radiation dermatitis is demanding. The majority of the interventions are based only on clinical practice. Telangiectasia may be treated with pulse dye laser therapy. Chronic postirradiation wounds need special dressings. In case of necrosis or severe ulceration, surgical intervention may be considered. Management of RIF should be complex. Available methods are rehabilitative care, pharmacotherapy, hyperbaric oxygen therapy, and laser therapy. Future challenges include the assessment of late skin toxicity in modern irradiation techniques. Special attention should be paid on genomics and radiomics that allow scientists and clinicians to select patients who are at risk of the development of chronic radiation dermatitis. Novel treatment methods and clinical trials are strongly needed to provide more efficacious therapies.

The Pattern of Failure After Reirradiation of Recurrent Squamous Cell Head and Neck Cancer: Implications for Defining the Targets

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

Popovtzer, Aron; Gluck, Iris; Chepeha, Douglas B.

2009-08-01

Purpose: Reirradiation (re-RT) of recurrent head and neck cancer (HNC) may achieve long-term disease control in some patients, at the expense of high rates of late sequelae. Limiting the re-RT targets to the recurrent gross tumor volume (rGTV) would reduce the volumes of reirradiated tissues; however, its effect on tumor recurrence pattern is unknown. Methods and Materials: This is a retrospective review of 66 patients who underwent curative-intent re-RT for nonresectable recurrent or second primary mucosal squamous cell HNC. Treatment was delivered with three-dimensional conformal (3D) RT or intensity-modulated RT (IMRT). The targets in all patients consisted of the rGTVsmore » with tight (0.5-cm) margins, with no intent to treat prophylactically lymph nodes or subclinical disease in the vicinity of the rGTVs. The sites of locoregional failures (LRFs) were determined using imaging at the time of failure and were compared with the rGTVs. Results: Median re-RT dose was 68 Gy. Forty-seven patients (71%) received concomitant chemotherapy, and 31 (47%) received hyperfractionated, accelerated RT. At a median follow-up of 42 months, 16 (23%) were alive and disease-free. Fifty patients (77%) had a third recurrence or persistent disease, including 47 LRFs. All LRFs occurred within the rGTVs except for two (4%) (95% confidence interval, 0-11%). Nineteen patients (29%) had Grade {>=} 3 late complications, mostly dysphagia (12 patients). Conclusions: Almost all LRFs occurred within the reirradiated rGTVs despite avoiding prophylactic RT of tissue at risk of subclinical disease. These results support confining the re-RT targets to the rGTVs to reduce reirradiated tissue volumes.« less

The authors' clinical experience is presented of non-structural valvular dysfunction of the prosthetic aortic valve caused by pannus ingrowth during the late postoperative period after previous heart valve surgery. Between January 1999 and April 2012, at the authors' institution, a total of 33 patients underwent reoperation for increased mean pressure gradient of the prosthetic aortic valve. All patients were shown to have pannus ingrowth. The mean interval from the previous operation was 16.7 +/- 4.3 years, and the most common etiology for the previous aortic valve replacement (AVR) was rheumatic valve disease. The mean effective orifice area index (EOAI) of the previous prosthetic valve was 0.97 +/- 0.11 cm2/m2, and the mean pressure gradient on the aortic prosthesis before reoperation was 39.1 +/- 10.7 mmHg. Two patients (6.1%) died in-hospital, and late death occurred in six patients (18.2%). At the first operation, 30 patients underwent mitral or tricuspid valve surgery as a concomitant procedure. Among these operations, mitral valve replacement (MVR) was combined in 24 of all 26 patients with rheumatic valve disease. Four patients underwent pannus removal only while the prosthetic aortic valve was left in place. The mean EOAI after reoperation was significantly increased to 1.16 +/- 0.16 cm2/m2 (p < 0.001), and the mean pressure gradient was decreased to 11.9 +/- 1.9 mmHg (p < 0.001). Non-structural valvular dysfunction caused by pannus ingrowth was shown in patients with a small EOAI of the prosthetic aortic valve and combined MVR for rheumatic disease. As reoperation for pannus overgrowth showed good clinical outcomes, an aggressive resection of pannus and repeated AVR should be considered in symptomatic patients to avoid the complications of other cardiac diseases.

Lobectomy is preferred in thyroid cancer to decrease surgical complications and avoid lifelong thyroid-hormone replacement. However, postoperative hypothyroidism, requiring thyroid-hormone replacement, may occur. We aimed to identify the incidence and risk factors of postoperative hypothyroidism to develop a surveillance strategy after lobectomy for papillary thyroid microcarcinoma (PTMC). This historical cohort study involved 335 patients with PTMC treated by lobectomy. Postoperative thyroid functions were measured regularly, and patients were prescribed levothyroxine according to specific criteria. Patients not satisfying hormone-replacement criteria were closely followed up. Postoperative hypothyroidism occurred in 215 patients (64.2%) including 5 (1.5%) with overt hypothyroidism and 210 (62.7%) with subclinical hypothyroidism. Forty patients (11.9%) were required thyroid hormone replacement. One hundred nineteen patients (33.5%) experienced temporary hypothyroidism and spontaneously recovered to euthyroid state. High preoperative thyroid-stimulating hormone (TSH) was the most important factor predicting postoperative hypothyroidism and failure of recover from hypothyroidism (odds ratio [OR], 2.82 and 1.77; 95% confidence interval [CI], 2.07 to 3.95 and 1.22 to 2.63; P < 0.001 and 0.002, respectively). Of the 215 patients eventually developing postoperative hypothyroidism, 70 (32.6%) developed hypothyroidism after the first postoperative year. Postoperative 1-year TSH levels were able to differentiate patients developing late hypothyroidism or euthyroidism (OR, 2.29; 95% CI, 1.68 to 3.26; P < 0.001). Preoperative and postoperative TSH levels might be predictive for patients who develop postlobectomy hypothyroidism and identify those requiring long-term surveillance for hypothyroidism. Additionally, mild postoperative hypothyroidism cases should be followed up without immediate levothyroxine replacement with the expectation of spontaneous recovery.

In girls with congenital adrenal hyperplasia (CAH), genital ambiguity usually leads to a rapid neonatal diagnosis. Rarely, CAH causes complete virilization and male sex assignment with a delayed diagnosis. After being confronted with very specific problems in two of such patients, we collected data of patients with CAH and complete virilization in a nationwide study to delineate specific problems of these rare patients in order to improve their management. Through the German Working Group of Paediatric Endocrinology (Arbeitsgemeinschaft Pädiatrische Endokrinologie, APE), questionnaires were sent to all members caring for patients with CAH and complete virilization in their endocrine clinics. Data from 16 patients from 10 paediatric endocrine centres were assessed by questionnaire. The following problems have been encountered. (1) Sex assignment/gender identity: initially all patients had a male sex assignment. Six patients were diagnosed during the first month of life. Five were reassigned to female sex immediately, one at the age of 19 months. Except in one girl demonstrating some tomboyish behaviour, gender role behaviour in these patients did not differ from unaffected girls. Ten patients were diagnosed late at 3.4--7 years of age. In seven patients with a late diagnosis, male sex assignment was maintained; one of them expressed some concerns about living as a male. In three patients late sex reversal was performed, gender identity is very poor in one and new sex assignment is currently under consideration. (2) SURGERY: irrespective of the sex assigned, all patients had between one and three surgical procedures, including clitoris reduction and (repeated) vaginoplasties in patients with female sex assignment. Hysterectomy and ovarectomy were performed in patients with male sex assignment. (3) Short stature: patients with a late diagnosis of CAH had extremely advanced bone ages of +6.3 to +9.5 years, leading to severely reduced final height of 137 to 150 cm in adult patients. Patients tended to follow height percentiles of genetic females. One pubertal patient was suicidal due to short stature. (4) Central precocious puberty (CPP): prolonged exposition to adrenal androgens led to CPP in one patient. He was treated with GnRH analogues until gonadectomy. Patients with CAH and complete virilization have a high risk of being diagnosed late. There are major problems and uncertainties of the patients' families and the treating physicians concerning gender assignment. Gender identity is disturbed in some patients. In addition, multiple surgical procedures are necessary and short stature as well as central precocious puberty might be important to avoid late sequelae. While some surgical interventions are probably unavoidable, most of these issues could be resolved with an early diagnosis. Thus, especially for these patients, a neonatal screening programme for CAH would be of paramount importance.

Contact lens complications.

Complications associated with contact lenses range from mild to severe and occur with all lens modalities. Contact lens wear can cause a change in corneal physiology, which can lead to epithelial, stromal, and endothelial compromise. Other complications include lens deposition, allergic conjunctivitis, giant papillary conjunctivitis, peripheral infiltrates, microbial keratitis, and neovascularization. Pre-existing conditions can contribute to these complications, or they can occur in association with contact lens wear and care regimens. Patient-related factors, such as alteration of the recommended wearing or replacement schedules and noncompliance with recommended contact lens care regimens for economic reasons, convenience, or in error, contribute to contact lens-related complications and have led to difficulty in accurate determination of complication rates among the various lens wear modalities. Complications may require discontinuation of contact lenses, topical therapy, and changes in contact lens wearing schedules, materials, and care solutions. On initial lens fitting and follow-up evaluations, practitioners should review contact lens replacement and cleaning regimens with patients and discuss complications. To avoid serious complications, patients should be reminded to remove their contact lenses as soon as ocular irritation occurs, and to call their eye care practitioner immediately if symptoms persist.

Background. Although patients with Hodgkin's lymphoma (HL) achieve prolonged survival, long-term complications are a major cause of morbidity and mortality among long-term survivors of HL. Methods. We retrospectively evaluated long-term complications in 336 HL survivors treated between January 1990 and January 2006 at the Department of Medical Oncology of the Hacettepe University Institute of Oncology who were >16 years old at presentation. All patients were regularly followed up every 3 months for the first 2 years after complete response, biannually for 3 years, and annually after 5 years. Results. Median follow-up was 8.5 years. The mean age (±SD) of the patients at the time of diagnosis was 35.7 ± 13.1 years. The male to female ratio was 61%/39%. During follow-up, 29 second malignancies (8.6%) were diagnosed in 28 patients with HL; 22 were solid tumors and 7 were hematological malignancies. Forty-seven (14.0%) of all patients with HL were found to have thyroid abnormalities. During follow-up, 54 (16.1%) patients developed cardiovascular complications. Overall, 29 (8.6%) patients developed late pulmonary toxicities. The cumulative number of chronic viral infections was 13 (3.9%). Conclusions. Long-term survivors of HL need to be properly followed up not only for disease control but also for evaluation of possible late morbidities to minimize the consequences.

Pregnancy-associated Death - Clarifying the Cause of Death and Medico-legal Assessments in Accusations of Malpractice.

Pregnancy-associated deaths are extremely rare in Germany. Most deaths are from natural causes, and a range of causes are possible. The deaths of 22 women who died of pregnancy-associated causes and who were autopsied in the Institute of Forensic Medicine of Justus-Liebig University Gießen between 1992 and 2016 were analyzed. The autopsy results and histological examinations for the majority of women who died of pregnancy-associated causes between 1992 and 2016 showed that they had died of natural causes, although complications of pregnancy were a leading cause of death. The death of a pregnant woman should not automatically raise the suspicion of malpractice, although the question does arise in cases of bleeding complications only detected at very late stages. Experts must prove that a real mistake was made during treatment and provide evidence of the causality between malpractice and patient death. Particularly when well-known complications of pregnancy were present, this is only the case if poor monitoring resulted in the complication being detected too late or if treatment was not in accordance with accepted standards of care. The majority of pregnancy-associated deaths are from natural causes and the death of a pregnant woman does not mean that medical malpractice was involved, although this accusation is often levelled in cases where rupture was not immediately diagnosed or in cases of fatal postpartum hemorrhage.

The authors report the history of a 74-year-old patient who underwent surgical treatment for segmental knee-joint periprosthetic bone loss using structural proximal tibial allografts coated with serum albumin. Successful treatment of late complications which occurred in the postoperative period is also described. The authors emphasize that bone replacement with allografts is a physiological process that enables the stable positioning of the implant and the reconstruction of the soft tissues, the replacement of extensive bone loss, and also it is a less expensive operation. It has been already confirmed that treatment of lyophilised allografts with albumin improves the ability of bone marrow-derived mesenchymal stem cells to adhere and proliferate the surface of the allografts, penetrate the pores and reach deeper layers of the graft. Earlier studies have shown osteoblast activity on the surface and interior of the graft.

Medulloblastoma is the most frequent malignant brain tumour in children. Radiation-induced cavernous haemangiomas (RICHs) are a known late complication of radiation exposure, especially in young children. We present a patient who underwent subtotal resection of posterior fossa medulloblastoma with subsequent chemotherapy and radiotherapy at the age of 10 years. A new lesion in the region of the left foramen of Monro appeared 16 years later. Based on the imaging results, metastasis or radiation-induced cavernoma was considered. The lesion had the same appearance on imaging as a rarely published intraventricular cavernoma of the foramen of Monro. Unlike the cavernoma of the foramen of Monro, this lesion was subependymal and intraforniceal. Using electromagnetic navigation and neuroendoscopy, the lesion was completely removed. Histopathological examination revealed a cavernous haemangioma. This is a unique case of intraforniceal paraforaminal cavernoma that was successfully removed endoscopically using electromagnetic neuronavigation and without neurological sequelae.

Parastomal hernia is the most common late stomal complication. Its appearance is usually asymptomatic. We report a parastomal hernia containing stomach. A 69-year-old patient with end colostomy arrived at the emergency room presenting with abdominal pain associated with vomiting and functioning stoma. She had a distended and painful abdomen without signs of peritoneal irritation and pericolostomic eventration in the left iliac fossa. X-ray visualized gastric fornix dilatation without dilated intestine bowels, and computed tomography showed parastomal incarcerated gastric herniation. Gastrografin (Bayer Australia Limited, New South Wales, Australia) was administered, showing no passage to duodenum. She underwent surgery, with stomal transposition and placement of onlay polypropylene mesh around the new stoma. Parastomal hernias are a frequent late complication of colostomy. Only four gastric parastomal hernia cases are reported in the literature. Three of these four cases required surgery. The placement of prosthetic mesh in the moment of stoma elaboration should be considered as a potential preventive measure. PMID:25058773

Advances in diagnostics, treatment strategies, and supportive care have contributed to a marked improvement in outcomes for children with cancer. This has resulted in a growing number of long-term childhood cancer survivors. Currently there are over 360,000 individuals who are survivors of childhood cancer in the United States. However, treatment for patients with childhood cancer with chemotherapy, radiation, and/or hematopoietic stem cell transplantation can result in health-related complications that may not become evident until years after completion of treatment. As a result, several initiatives have been established to help standardize the surveillance for treatment-related late effects in childhood cancer survivors. This review highlights emerging concepts related to commonly reported late effects, such as subsequent malignant neoplasms, cardiovascular disease, and endocrinopathies. It also discusses relevant population-based screening strategies to mitigate the long-term health-related burden in vulnerable populations of survivors.

The timing of reconstruction in severe mechanical trauma.

Serious ocular trauma involving the posterior segment remains rather common and, despite many technological advances in recent years, continues to represent a significant management challenge to the ophthalmologist. One of these challenges is to identify the most optimal timing for the ultimate reconstruction, namely vitrectomy. While it is fairly obvious that suture-closure of the wound of open-globe injuries should be done as soon as possible, it is less clear whether vitrectomy should be performed in the same surgical session (primary comprehensive reconstruction) or be deferred (staged approach), and if so for how long. In this review, 4 options for staging are offered: early (days 2-4); delayed (days 5-7); late (days 8-14), and very late (past 2 weeks). The earlier the vitrectomy, the higher the risk of intraoperative complications. Conversely, the later the vitrectomy, the higher the incidence and severity of postoperative complications, of which proliferative vitreoretinopathy is the most damaging.

Predicting the risk factors for late aortic events in patients with type B acute aortic dissection without complications may help to determine a therapeutic strategy for this disorder. We investigated whether late aortic events in type B acute aortic dissection can be predicted accurately by an index that expresses the degree of fusiform dilatation of the proximal descending aorta during the acute phase; this index can be calculated as follows: (maximum diameter of the proximal descending aorta)/(diameter of the distal aortic arch + diameter of the descending aorta at the pulmonary artery level). Patients with type B acute aortic dissection without complications (n = 141) were retrospectively analyzed to determine the predictors of late aortic events; these include aortic dilatation, rupture, refractory pain, organ ischemia, rapid aortic enlargement, and rapid enlargement of ulcer-like projections. The fusiform index in patients with late aortic events (0.59) was higher than that in patients without late aortic events (0.53, P < .01). Patients with a higher fusiform index exhibited aortic dilatation earlier than those with a lower fusiform index. By multivariate analysis, we conclude that the predominant independent predictors of late aortic events were a maximum aortic diameter of 40 mm or more, a patent false lumen, and a fusiform index of 0.64 or more (hazard ratios, 3.18, 2.64, and 2.73, respectively). The values of actuarial freedom from aortic events for patients with all 3 predictors at 1, 5, and 10 years were 22%, 17%, and 8%, respectively, whereas the values in those without these predictors were 97%, 94%, and 90%, respectively. The degree of fusiform dilatation of the proximal descending aorta, a patent false lumen, and a large aortic diameter can be predominant predictors of late aortic events in patients with type B acute aortic dissection. Patients with these predictors should be recommended to undergo early interventions (surgery or stent-graft implantation) or at least be closely followed up during the chronic phase before such events develop.

Abstract Objective We previously demonstrated that parents whose children die in a pediatric intensive care unit (PICU) have a high level of complicated grief symptoms 6 months after the death. In this study, we investigate the change in the extent of complicated grief symptoms among these parents between 6 and 18 months postdeath and identify factors predicting improvement. Methods One hundred thirty-eight parents of 106 children completed surveys at 6 and 18 months. Surveys included the Inventory of Complicated Grief (ICG), measures of grief avoidance, attachment, caregiving and social support, and demographics. Multivariable analysis was performed using generalized estimating equations to identify characteristics independently associated with improvement in ICG score. Results ICG scores were 33.4 ± 13.6 at 6 months and 28.0 ± 13.5 at 18 months, representing an improvement in ICG score of 5.4 + 8.0 (95% confidence interval [CI] 4.1–6.8, p < 0.001). Variables independently associated with greater improvement in ICG score included traumatic death and greater grief avoidance. Variables independently associated with less improvement included being the biological parent and having more responsive caregiving. Parents with one or two surviving children had more improvement in ICG score than those with no surviving children whereas parents with three or more surviving children had less improvement. Conclusion Complicated grief symptoms decrease among parents between 6 and 18 months after their child's death in the PICU; however, high symptom levels persists for some. Better understanding of the trajectory of complicated grief will allow parents at risk for persistent distress to receive professional support. PMID:21281122

An efficient approach for inverse kinematics and redundancy resolution scheme of hyper-redundant manipulators

Hyper redundant manipulators have a large number of degrees of freedom (DOF) than the required to perform a given task. Additional DOF of manipulators provide the flexibility to work in highly cluttered environment and in constrained workspaces. Inverse kinematics (IK) of hyper-redundant manipulators is complicated due to large number of DOF and these manipulators have multiple IK solutions. The redundancy gives a choice of selecting best solution out of multiple solutions based on certain criteria such as obstacle avoidance, singularity avoidance, joint limit avoidance and joint torque minimization. This paper focuses on IK solution and redundancy resolution of hyper-redundant manipulator using classical optimization approach. Joint positions are computed by optimizing various criteria for a serial hyper redundant manipulators while traversing different paths in the workspace. Several cases are addressed using this scheme to obtain the inverse kinematic solution while optimizing the criteria like obstacle avoidance, joint limit avoidance.

Case series of four dogs in which extensive bite wounds had been treated using octenidine dihydrochloride (Octenivet® or Octenisept®) flushing. The dogs subsequently developed severe local complications. Retrospective evaluation of clinical symptoms, diagnostics, therapy and course of the disease. In four dogs, severe necrosis and persistent edematous changes of the treated area developed after the application of octenidine dihydrochloride. The clinical course was comparable to complications described previously in human medicine. Therapy was protracted and complicated by secondary wound infection. Irrigation of deep wounds, particularly bite wounds, using octenidine dihydrochloride without drainage may lead to persistent edematous changes, inflammatory reactions and necrosis. The inappropriate application of octenidine dihydrochloride for wound irrigation should be avoided in veterinary medicine.

Plasmapheresis it is a therapeutic method based on extracorporeal plasma exchange. First attempts at treatment with plasmapheresis date back to the beginning of the 20th century. However, it was first brought to clinical practice only in the 1950s as a way of treating Waldenstrom macroglobulinemia and in last decades a dynamic improvement in this method has been observed. At the moment plasmapheresis is used in the treatment of over 150 diseases. Like every invasive method, it may cause complications, which are due to anticoagulation, the use of replacement fluids, the technical part of the procedure, and the presence of intravenous catheters. The knowledge of potential complications and the way of preventing them by the medical staff help to avoid complications and to decrease their harmful effects.

Biological mechanisms of normal tissue damage: importance for the design of NTCP models.

The normal tissue complication probability (NTCP) models that are currently being proposed for estimation of risk of harm following radiotherapy are mainly based on simplified empirical models, consisting of dose distribution parameters, possibly combined with clinical or other treatment-related factors. These are fitted to data from retrospective or prospective clinical studies. Although these models sometimes provide useful guidance for clinical practice, their predictive power on individuals seems to be limited. This paper examines the radiobiological mechanisms underlying the most important complications induced by radiotherapy, with the aim of identifying the essential parameters and functional relationships needed for effective predictive NTCP models. The clinical features of the complications are identified and reduced as much as possible into component parts. In a second step, experimental and clinical data are considered in order to identify the gross anatomical structures involved, and which dose distributions lead to these complications. Finally, the pathogenic pathways and cellular and more specific anatomical parameters that have to be considered in this pathway are determined. This analysis is carried out for some of the most critical organs and sites in radiotherapy, i.e. spinal cord, lung, rectum, oropharynx and heart. Signs and symptoms of severe late normal tissue complications present a very variable picture in the different organs at risk. Only in rare instances is the entire organ the critical target which elicits the particular complication. Moreover, the biological mechanisms that are involved in the pathogenesis differ between the different complications, even in the same organ. Different mechanisms are likely to be related to different shapes of dose effect relationships and different relationships between dose per fraction, dose rate, and overall treatment time and effects. There is good reason to conclude that each type of late complication after radiotherapy depends on its own specific mechanism which is triggered by the radiation exposure of particular structures or sub-volumes of (or related to) the respective organ at risk. Hence each complication will need the development of an NTCP model designed to accommodate this structure. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Abstract Objective: In the antibiotic era, purulent pericarditis is a rare entity. However, there are still reports of cases of the disease, which is associated with high mortality, and most such cases are attributed to delayed diagnosis. Approximately 40-50% of all cases of purulent pericarditis are caused by Gram-positive bacteria, Streptococcus pneumoniae in particular. Methods: We report four cases of pneumococcal pneumonia complicated by pericarditis, with different clinical features and levels of severity. Results: In three of the four cases, the main complication was cardiac tamponade. Microbiological screening (urinary antigen testing and pleural fluid culture) confirmed the diagnosis of severe pneumococcal pneumonia complicated by purulent pericarditis. Conclusions: In cases of pneumococcal pneumonia complicated by pericarditis, early diagnosis is of paramount importance to avoid severe hemodynamic compromise. The complications of acute pericarditis appear early in the clinical course of the infection. The most serious complications are cardiac tamponade and its consequences. Antibiotic therapy combined with pericardiocentesis drastically reduces the mortality associated with purulent pericarditis. PMID:26398760

We report the case of a patient with a history of a complicated revisional bariatric operation who developed a lung pseudosequestration secondary to a gastro-pulmonary fistula. As the patient presented with recurrent hemoptysis, she was initially submitted to embolization of the aberrant vessels and later to a definite operation, which consisted on a diversion of the gastric fistula into a Roux-en-Y intestinal loop. It is an exceptional case about late complications of bariatric surgery, and it underlines the importance of discarding these complications even when the clinical manifestations affect another anatomic region different from the operated abdomen.

Follow-up imaging after endovascular aortic aneurysm repair (EVAR) focuses on detection of gross abnormalities: endoleaks and significant (>10 mm) migration. Precise determination of endograft position and wall apposition may predict late complications. We present a new measurement method to determine precise position and apposition of endografts in the aortic neck. Four patients were selected from our EVAR database. These patients had late (>1 year) type IA endoleak or >1 cm endograft migration. Twenty patients with uneventful follow-up were measured as controls. The new software adds six parameters to define endograft position and neck apposition: fabric distance to renal arteries, tilt, endograft expansion (% of the maximum original diameter), neck surface, apposition surface, and shortest apposition length. These parameters were determined on preoperative and all available postoperative CT-scans, to detect subtle changes during follow-up. All patients with endoleak or migration had increases in fabric distance, tilt, or endograft expansion or decrease of apposition surface. Changes occurred at least one CT scan before the endoleak or migration was noted in the CT reports. The patient without complications showed no changes in position or apposition during follow-up. The new measurement method detected subtle changes in endograft position and apposition during CT follow-up, not recognized initially. It can potentially determine endograft movements and decrease of apposition surface before they lead to complications like type IA endoleaks or uncorrectable migration. A larger follow-up study comparing complicated and non-complicated EVAR patients is needed to corroborate these results.

The objective of this study was to compare the efficacy and safety of laser versus conventional endoforehead lifting. Over a period of 12 years (January 2000-January 2012), a total of 110 patients with hyperactive muscles over the frontal region have been collected for a retrospective study. The SurgiLase 150XJ CO 2 laser system, in conjunction with the flexible FIBERLASE, was used. The endoscope was 4 mm in diameter with an angle of 30°. The primary efficacy measurement was the assessment of the final outcome for using laser vs. conventional methods. Both groups were observed at three weeks, six weeks and six months after surgery. The most common complication in early convalescence (three weeks) was swelling. This was followed by local paraesthesia, ecchymosis, localized hematomas and scar with alopecia. All these problems disappeared completely after the 6-month study period. Based on a chi-square analysis, there were clinically and statistically significant differences favouring the laser endoforehead surgery in the operative time, early and late complications. All patients achieved significant improvement after both laser and conventional endoforehead surgery in the final outcome. However, the early and late complications indicated a greater difference in the laser group.

The retropubic tension-free vaginal tape (TVT) procedure replaced Burch colposuspension as the primary surgical method for stress urinary incontinence (SUI) and mixed urinary incontinence (MUI) in women in our department in 1998. In this study we compared the short-term and long-term clinical outcomes of these surgical procedures. Using a case series design, we compared the last 5 years of the Burch procedure (n = 127, 1994-1999) with the first 5 years of the retropubic TVT procedure (n = 180, 1998-2002). Information from the medical records was transferred to a case report form comprising data on perioperative and long-term complications as well as recurrence of UI, defined as bothersome UI or UI in need of repeat surgery. Other endpoints were rates of perioperative and late complications and the rates of prolapse surgery after primary surgery. The data were analyzed with the chi-squared and t tests and survival analysis using SPSS. The cumulative recurrence rate of SUI in women with preoperative SUI was significantly higher after the Burch procedure, but no difference was observed in women with MUI. There were no significant differences in rates of perioperative and late complications. At 12 years there was a significant increase in rates of repeat surgery for incontinence and prolapse in women after the Burch procedure. The long-term efficacy of TVT surgery was superior to that of Burch colposuspension in women with SUI. In addition, the rate of late prolapse surgery was significantly higher after the Burch procedure.

The objective of the study was to investigate the potential role of impaired factor XII-dependent activation of fibrinolysis in treated antiphospholipid syndrome gestations developing late-pregnancy complications. This was a prospective study in a third-level teaching hospital, including 75 patients: 25 pregnant patients having the antiphospholipid syndrome and carrying their pregnancies until 26 weeks' gestation or later (group 1); 25 pregnant patients having normal term pregnancies and delivery and no previous miscarriage (group 2); and 25 pregnant patients being diagnosed as having severe pre-eclampsia and/or intrauterine growth restriction but testing negative for antiphospholipid antibodies (group 3). Hemostatic evaluation was carried out from patients in groups 1 and 2 between 6 and 10 weeks, between 18 and 22 weeks, and between 28 and 32 weeks' gestation. Patients in group 3 were sampled between 28 and 32 weeks. An additional blood sample was obtained 4 to 6 months after delivery (baseline). The Mann-Whitney U test, the Friedman test, and the chi2 test were used. Patients in group 1 were characterized by increased factor VIIa levels, increased prothrombin fragment 1+2 levels, reduced factor XIIa levels, diminished functional urokinase-type plasminogen activator levels, and decreased levels of plasmin/alpha-2-plasmin inhibitor complexes. These abnormalities were more evident in patients in group 1 developing pre-eclampsia and/or intrauterine growth restriction. Impaired factor XIIa-dependent activation of fibrinolysis seems to be a key mechanism related to late-pregnancy complications in patients with the antiphospholipid syndrome.

Purpose: To determine the feasibility of combined long-term androgen deprivation therapy (ADT) and dose escalation with high-dose-rate (HDR) brachytherapy. Methods and Materials: Between 2001 and 2007, 200 patients with high-risk prostate cancer (32.5%) or very high-risk prostate cancer (67.5%) were prospectively enrolled in this Phase II trial. Tumor characteristics included a median pretreatment prostate-specific antigen of 15.2 ng/mL, a clinical stage of T2c, and a Gleason score of 7. Treatment consisted of 54 Gy of external irradiation (three-dimensional conformal radiotherapy [3DCRT]) followed by 19 Gy of HDR brachytherapy in four twice-daily treatments. ADT started 0-3 months before 3DCRT and continuedmore » for 2 years. Results: One hundred and ninety patients (95%) received 2 years of ADT. After a median follow-up of 3.7 years (range, 2-9), late Grade {>=}2 urinary toxicity was observed in 18% of the patients and Grade {>=}3 was observed in 5%. Prior transurethral resection of the prostate (p = 0.013) and bladder D{sub 50} {>=}1.19 Gy (p = 0.014) were associated with increased Grade {>=}2 urinary complications; age {>=}70 (p = 0.05) was associated with Grade {>=}3 urinary complications. Late Grade {>=}2 gastrointestinal toxicity was observed in 9% of the patients and Grade {>=}3 in 1.5%. CTV size {>=}35.8 cc (p = 0.007) and D{sub 100} {>=}3.05 Gy (p = 0.01) were significant for increased Grade {>=}2 complications. The 5-year and 9-year biochemical relapse-free survival (nadir + 2) rates were 85.1% and 75.7%, respectively. Patients with Gleason score of 7-10 had a decreased biochemical relapse-free survival (p = 0.007). Conclusions: Intermediate-term results at the 5-year time point indicate a favorable outcome without an increase in the rate of late complications.« less

Purpose To compare the risks of serious health outcomes among hematopoietic cell transplantation (HCT) survivors versus a matched population of patients with cancer who did not undergo HCT, where the primary difference may be exposure to HCT. Methods Two-year HCT survivors treated at a comprehensive cancer center from 1992 through 2009 who were Washington State residents (n = 1,792; 52% allogeneic and 90% hematologic malignancies) were frequency matched by demographic characteristics and underlying cancer diagnosis (as applicable) to non-HCT 2-year cancer survivors, using the state cancer registry (n = 5,455) and the general population (n = 16,340) using driver's license files. Late outcomes for all three cohorts were ascertained from the state hospital discharge and death registries; subsequent cancers were ascertained from the state cancer registry. Results After median follow-up of 7.1 years, HCT survivors experienced significantly greater rates of hospitalization compared with matched non-HCT cancer survivors (280 v 173 episodes per 1,000 person-years, P < .001) and greater all-cause mortality (hazard ratio [HR], 1.1; 95% CI, 1.01 to 1.3). HCT survivors had more hospitalizations or death with infections (10-year cumulative incidence, 31% v 22%; HR, 1.4; 95% CI, 1.3 to 1.6) and respiratory complications (cumulative incidence, 27% v 20%; HR, 1.4; 95% CI, 1.2 to 1.5). Risks of digestive, skin, and musculoskeletal complications also were greater among HCT versus non-HCT cancer survivors. The two groups had similar risks of circulatory complications and second cancers. Both HCT and non-HCT cancer survivors had significantly greater 10-year cumulative incidences of all major organ-system outcomes versus the general population. Conclusion History of HCT was associated with late morbidity and mortality among cancer survivors. In particular, clinicians who care for HCT survivors should be aware of their high rates of late respiratory and infectious complications.

Urea cycle disorders (UCDs) most often involve inherited deficiencies in genes that code for enzymes normally used by the urea cycle to breakdown nitrogen. UCDs lead to serious metabolic complications, including severe neurologic decompensation related to hyperammonemia. Although the majority of UCDs are revealed soon after birth, stressful events in adulthood can lead to unmasking of a partial, late-onset UCDs. In this report, we describe a late-onset UCD unmasked by severe malnutrition. Early, specialized nutrition therapy is a fundamental aspect of treating hyperammonemic crises in patients with UCD. The case presented here demonstrates the importance of early recognition of UCD and appropriate interventions with nutrition support. Copyright © 2014 Elsevier Inc. All rights reserved.

Tsou, Ming-Cheng; Kao, Sheng-Long; Su, Chien-Min

When an officer of the watch (OOW) faces complicated marine traffic, a suitable decision support tool could be employed in support of collision avoidance decisions, to reduce the burden and greatly improve the safety of marine traffic. Decisions on routes to avoid collisions could also consider economy as well as safety. Through simulating the biological evolution model, this research adopts the genetic algorithm used in artificial intelligence to find a theoretically safety-critical recommendation for the shortest route of collision avoidance from an economic viewpoint, combining the international regulations for preventing collisions at sea (COLREGS) and the safety domain of a ship. Based on this recommendation, an optimal safe avoidance turning angle, navigation restoration time and navigational restoration angle will also be provided. A Geographic Information System (GIS) will be used as the platform for display and operation. In order to achieve advance notice of alerts and due preparation for collision avoidance, a Vessel Traffic Services (VTS) operator and the OOW can use this system as a reference to assess collision avoidance at present location.

2006-01-01

Anxiety symptoms are frequently present in patients with late-life depression. The designation “anxious depression” has been used to describe major depressive disorder (MDD) accompanied by clinically significant but subsyndromal anxiety symptoms. MDD may also present comorbid with diagnosable anxiety disorders, although this presentation is less common in late life. Diagnosis of anxious depression in the elderly is complicated by several factors (eg, their tendency to experience and report psychiatric symptoms as somatic illness) and is associated with a more severe clinical presentation, increased risk for suicidal ideation, increased disability, and poorer prognosis. Standard pharmacotherapy for depression may be sufficient but for many patients must be modified or augmented. Psychosocial interventions may also be an important component in the treatment of these patients, although no specific psychosocial treatments have been developed for late-life anxious depression.

Objective Evidence for optimal timing of delivery for some pregnancy complications at late preterm gestation is limited. The purpose of this study was to identify center variation of indicated late preterm births. Study design Analysis of singleton late preterm and term births from a large U.S. retrospective obstetrical cohort. Births associated with spontaneous preterm labor, major congenital anomalies, chorioamnionitis, and emergency cesarean were excluded. We used modified Poisson fixed effects logistic regression with interaction terms to assess center variation of indicated late preterm births associated with four medical/obstetric comorbidities after adjusting for socio-demographics, co-morbidities, and hospital/provider characteristics. Results We identified 150,055 births from 16 hospitals; 9218 were indicated late preterm births. We found wide variation of indicated late preterm births across hospitals. The extent of center variation was greater for births associated with preterm premature rupture of membranes (RR across sites: 0.45 – 3.05), hypertensive disorders of pregnancy (RR across sites: 0.36 – 1.27), and placenta previa/abruption (RR across sites: 0.48 – 1.82). We found less center variation for births associated with diabetes (RR across sites: 0.65 – 1.39). Conclusion Practice variation in the management of indicated late preterm deliveries might be a source of preventable late preterm birth. PMID:27120474

Utilization of the Bridging Strategy for the Development of New Drugs in Oncology to Avoid Drug Lag.

Global trial (GT) strategy and bridging (BG) strategy are currently the main clinical development strategies of oncology drugs in Japan, but the relationship between development style and drug lag and how the bridging strategy has contributed to the solution of drug lag have not been clear. We investigated the potential factors that influenced submission lag (SL), and also compared the differences in SL among early-initiation BG strategy, late-initiation BG strategy, and GT strategy. A stepwise linear regression analysis identified the potential factors that shorten SL: development start lag and development style. Comparison of the differences in SL among the strategies also indicated that the SL in the GT strategy and that in the early-initiation BG strategy were significantly shorter than that in the late-initiation BG strategy. The findings in our study suggest that the late-initiation BG strategy may not contribute to shortening drug lag. Because the number of late-initiation BG studies has not decreased, we propose first that pharmaceutical companies should initiate clinical development as early as possible in Japan so that they can choose the GT strategy as a first option at the next step, and second when they cannot choose the GT strategy after investigating differences in exposure between Japanese and non-Japanese in a phase 1 study, they should select the early BG strategy to avoid future drug lag. It is also important for the regulatory authorities to provide reasonable guidance to have a positive impact on strategic decisions, even for foreign-capital companies. © 2017, The American College of Clinical Pharmacology.

2016-06-01

In daily practice, acute and chronic pulmonary diseases are common issues presenting to the anesthetist. Respiratory physiology in general is affected by both general and regional anesthesia, which results in an increased number of perioperative complications in pulmonary risk patients. Therefore, anesthetic management of patients with bronchial asthma needs to address different clinical topics: the physical appearance of pulmonary disease, type and extent of surgical intervention as well as effects of therapeutic drugs, anesthetics and mechanical ventilation on respiratory function. The present work describes important precautions in preoperative scheduling of the asthmatic patient. In the operative course, airway manipulation and a number of anesthetics are able to trigger intraoperative bronchial spasm with possibly fatal outcome. It is essential to avoid these substances to prevent asthma attack. If asthmatic status occurs, appropriate procedures according to therapeutic standards have to be applied to the patient. Postoperatively, sufficient pain therapy avoids pulmonary complications and improves outcome. © Georg Thieme Verlag Stuttgart · New York.

Mini-open lateral retroperitoneal lumbar spine approach using psoas muscle retraction technique. Technical report and initial results on six patients.

PubMed

2013-09-01

The main aim of this paper was to report reproducible method of lumbar spine access via a lateral retroperitoneal route. The authors conducted a retrospective analysis of the technical aspects and clinical outcomes of six patients who underwent lateral multilevel retroperitoneal interbody fusion with psoas muscle retraction technique. The main goal was to develop a simple and reproducible technique to avoid injury to the lumbar plexus. Six patients were operated at 15 levels using psoas muscle retraction technique. All patients reported improvement in back pain and radiculopathy after the surgery. The only procedure-related transient complication was weakness and pain on hip flexion that resolved by the first follow-up visit. Psoas retraction technique is a reliable technique for lateral access to the lumbar spine and may avoid some of the complications related to traditional minimally invasive transpsoas approach.

Oriental upper blepharoplasty.

PubMed

Weng, Chau-Jin

2009-02-01

Aesthetic surgery of the upper eyelids is a very common procedure performed in cosmetic practices around the world. The word blepharoplasty, however, has a different meaning in Asia than it does elsewhere. Orientals have different periorbital anatomic characteristics, their motivations for seeking eyelid treatment are different, and operative techniques have been adapted consequently. There are also many eyelid shapes among Orientals, mostly with regard to the presence and location of the supratarsal fold and/or presence of an epicanthal fold. The surgeon must therefore master a range of surgical procedures to treat these variations adequately. It is critical to know the indications for each blepharoplasty technique as well as their complications to select the right surgery and avoid unfavorable results. Epicanthoplasty performed on the right patient can greatly improve aesthetic results while retaining ethnic characteristics. This article will discuss Oriental eyelid characteristics, preoperative patient assessment, commonly used corrective techniques for the "double-eyelid" creation, and complications and how to avoid them.

2016-01-01

Hip dislocations are serious injuries as hip joint is an extremely stable joint. It requires a significant amount of force to produce such an injury. Anterior dislocations are uncommon. Potential complications of anterior hip dislocations are a neurovascular injury to femoral vessels or acetabular fractures. We report a rare late complication of Morel-Lavallee syndrome occurring 3 weeks after an anterior dislocation of the hip in a 43-year-old male. The patient presented to us with history. Morel-Lavallee syndrome is a rare complication. However if diagnosed early can be successfully treated with minimal burden to the patient. The authors recommend surgeons to have a high index of suspicion for this syndrome and a stringent follow-up examination of the patient.

A 26-year-old man presented with ipsilateral femur and ankle fractures. The patient was treated with interlocking nail of his femur fracture, followed by open reduction and internal fixation of his ankle fracture under tourniquet control. Postoperatively, the patient developed compartment syndrome of his thigh with elevated pressures, requiring decompressive fasciotomies. This case illustrates the possible complication of treating a femur fracture with intramedullary nailing and then immediately applying a tourniquet to treat an ipsilateral extremity fracture. Because of the complication with this patient, we feel the procedure should be staged, or a tourniquet should be avoided if possible.

Sclerotherapy is one treatment option for head and neck venous malformations (VMs). Evaluation of complication risks is, however, essential to improve its safety. We aimed to systematically report sclerotherapy complications by means of the Clavien-Dindo classification and to distinguish factors predisposing to complications. We identified our institution's head and neck VM patients who received sclerotherapy between 1 January 2007 and 31 August 2013, analyzed patient reports retrospectively, and applied to them the Clavien-Dindo classification. Our 75 VM patients underwent a total of 150 sclerotherapy sessions. The most common sclerosants were 3 % sodium tetradecyl sulfate and polidocanol. Complications occurred in 13 patients (17.3 %) and in 15 sessions (10.0 %); 3 complications required extensive postprocedural treatment and caused permanent morbidity, whereas 12 received conservative treatment. Patients with sclerotherapy complications underwent more treatments (p = 0.009) and more often needed further surgery (p = 0.007). We thus consider sclerotherapy a relatively safe treatment modality for head and neck VMs. To avoid complications, evaluation of VM characteristics and optimal treatment technique in a multidisciplinary team is vital.

Objectives and Method Information about aging-related change in coping is limited mainly to results of cross-sectional studies of age differences in coping, and no research has focused on predictors of aging-related change in coping behavior. To extend research in this area, we used longitudinal multilevel modeling to describe older adults’ (n=719; baseline M=61 years) 20-year, intra-individual approach and avoidance coping trajectories, and to determine the influence of two sets of predictors (threat appraisal and stressor characteristics; gender and baseline personal and social resources) on level and rate of change in these trajectories. Results Over the 20-year study interval participants declined in use of approach coping and most avoidance coping strategies, but there was significant variation in this trend. In simultaneous predictive models, female gender, more threat appraisal, stressor severity, social resources, and depressive symptoms; and fewer financial resources, were independently associated with higher initial levels of coping responses. Having more social resources, and fewer financial resources, at baseline in late-middle-age predicted faster decline over time in approach coping. Having more baseline depressive symptoms, and fewer baseline financial resources, hastened decline in use of avoidance coping. Independent of other variables in these models, decline over time in approach coping and avoidance coping remained statistically significant. Conclusion Overall decline in coping may be a normative pattern of coping change in later life. However, it also is modifiable by older adults’ stressor appraisals, their stressors, and the personal and social resources they possess at entry to later life, in late-middle age. PMID:22394319

Endoluminal Revision (OverStitch (TM) , Apollo Endosurgery) of the Dilated Gastroenterostomy in Patients with Late Dumping Syndrome After Proximal Roux-en-Y Gastric Bypass.

PubMed

Stier, Christine; Chiappetta, Sonja

2016-08-01

Dumping syndrome is a long-term postoperative complication of Roux-en-Y gastric bypass procedures. Morphologically, dumping syndrome usually correlates with a dilatation of the gastroenterostomy with accelerated pouch emptying. Conservative therapy includes diet changes, complementary pharmacotherapy and, if symptoms persist, surgical revision. Surgical options include endoscopic, endoluminal surgery to constrict the gastrojejunostomy using a novel endoscopic suturing device (OverStitch(TM), Apollo). In our study, we aimed to assess the viability, safety and efficacy of this procedure in patients with late dumping; 14 patients who had developed late dumping syndrome underwent surgery using an endoscopic suturing technique (OverStitch(TM), Apollo). Late dumping was confirmed by Sigstad score and an oral glucose tolerance test (OGTT). Prior to surgery, objective analysis of pouch emptying speed was assessed by gastric scintigraphy. Surgery was performed under general anaesthesia. None of the 14 patients suffered intra- or postoperative complications. No postsurgical increase in inflammation parameters was observed. The postinterventional pain scale (visual analogue scale) showed a mean score of 0.5 (range 0-10). In 13 of the 14 patients, no dumping was observed 1-month postsurgery. The postoperative Sigstad score (3.07 ± 2.06; range 1-9) showed an impressive reduction compared with the preoperative score (12.71 ± 4.18; range 7-24) (p < 0.001). Postoperative upper gastrointestinal gastrografin swallow revealed regular emptying in all the patients. The endoluminal endoscopic suturing technique-applied here for surgical revision of gastroenterostomy following Roux-en-Y gastric bypass-represents a promising, novel therapeutic option in late dumping syndrome involving minimal trauma and offering rapid reconvalescence.

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

[New technique for safe removal of impacted foreign bodies in the upper gastrointestinal tract using reusable variceal "cap" (cup, cap or cylinder)].

2012-01-01

The ingestion of a foreign body is one of the most common endoscopic emergencies. Foreign bodies in the upper gastrointestinal tract should be extracted as soon as possible to avoid serious complications such as perforation o bleeding. However, removals of foreign bodies with sharp edges are very difficult and can develop complications during their removal. Various devices have therefore been developed to prevent mucosal injury from the sharp edges during endoscopic extraction. We report a new technique for the successful foreign body extraction of upper digestive tract using the cap from six shooter variceal banding reused. We present 17 cases (9 males and 8 females). The types of foreign bodies removed were: chicken bones (n:7), fish bones (n:3), denture prosthesis (n:2), food bolus (n:2), long pin (n:1), golden thumb tack (n: 1) and press-through package (n:1). There were no complications. This new technique is safe and effective. Highlights its advantages: enhanced sight pharyngo esophageal junction, foreign bodies disimpact at that level, food bolus suck, avoid sharp object damage mucosal or scope and decrease time removal.

Preventing secondary infections among HIV-positive persons.

Secondary infectious diseases contribute substantially to morbidity and mortality of people infected with human immunodeficiency virus (HIV). The authors developed comprehensive, practical recommendations for prevention of infectious complications in HIV-infected people. Recommendations are concerned with the pathogens that are more common or more severe in HIV-infected people. Several infectious complications can be prevented by avoiding ingestion of contaminated food or water. Zoonoses can be prevented by precautions to be taken in contacts with animals. The risk of several fungal diseases can be reduced if activities likely to lead to inhalation of spores are avoided. HIV-infected people should be advised how to lower adverse health effects of travel, especially international travel. The potential for infectious complications of sexual activity and illicit drug use should be stressed, and recommendations to reduce the risk are discussed. Recommendations for use of vaccines in HIV-infected people are reviewed. Blood CD4+ lymphocyte concentrations, tuberculin skin testing, Toxoplasma serology, and sexually transmitted disease screening should be performed in certain subsets of HIV-infected people. Guidelines for chemoprophylaxis against Pneumocystis carinii and tuberculosis are presented. Recent data suggest that intravenous immunoglobulin therapy may prevent bacterial infections in HIV-infected children. PMID:1910184

Awake craniotomy (AC) with electrical cortical stimulation has become popular during the last ten years although the basic principles were introduced almost 50 years ago. The aim of this paper is to share with the readers our experience in 25 patients who underwent AC with electrical stimulation. Twenty-five patients who underwent AC between 2010 and 2013 are the subjects of this paper. All patients were diagnosed with intraaxial lesions involving the functional area itself or very close to it by preoperative imaging. During surgery, the functional area was demonstrated by cortical electrical stimulation and resection aimed to preserve it in order to avoid an irreversible functional deficit. Total resection was possible in 80% while in 20% subtotal resection had to be performed because of involvement of the functional area itself. The neurological complication rate was found to be 16% (4 patients) and all were transient. No complication regarding anesthesia was noted. Awake craniotomy in selected patients is very effective, safe and practical for supratentorial lesions close to the eloquent area. Complications related to the surgery itself are uncommon and general anesthesia is avoided. The hospital stay including the intensive care unit is short which makes it very economical surgical procedure.

Transforaminal lumbar interbody fusion (TLIF) is an effective treatment for patients with degenerative lumbar disc disorder. Contralateral radiculopathy, as a complication of TLIF, has been recognized in this institution, but is rarely reported in the literature. In this article, we report 2 cases of contralateral radiculopathy after TLIF in our institution and its associated complications. In the 2 cases, the postoperative computed tomography (CT) and magnetic resonance image (MRI) showed obvious upward movement of the superior articular process, leading to contralateral foraminal stenosis. Revision surgery was done at once to partially resect the opposite superior facet and to relieve nerve root compression. After revision surgery, the contralateral radiculopathy disappeared. Contralateral radiculopathy is an avoidable potential complication. It is very important to create careful preoperative plans and to conscientiously plan the use of intraoperative techniques. In case of postoperative contralateral leg pain, the patients should be examined by CT and MRI. If CT and MRI show that the superior articular process significantly migrated upwards, which leads to contralateral foraminal stenosis, revision surgery should be done at once to partially resect the contralateral superior facet so as to relieve nerve root compression and avoid possible long-term impairment.

2012-01-01

INTRODUCTION We describe our technique of percutaneous suprapubic catheter insertion with special reference to steps that help to avoid common complications of haematuria and catheter misplacement. METHODS The procedure is performed using a stainless steel reusable trocar under local infiltrative anaesthesia, usually at the bedside. After clinical confirmation of a full bladder, the trocar is advanced into the bladder through a skin incision. Once the bladder is entered, the obturator is removed and the assistant inserts a Foley catheter followed by rapid balloon inflation. Slight traction is applied to the catheter for about five minutes. Patients with previous lower abdominal surgery, an inadequately distended bladder or acute pelvic trauma do not undergo suprapubic catheterisation using this method. RESULTS The procedure was performed in 72 men (mean age: 42.4 years, range: 18–78 years) with urinary retention with a palpable bladder. The average duration of the procedure was less than five minutes. No complications were noted in any of the patients. CONCLUSIONS Trocar suprapubic catheter insertion is a safe and effective bedside procedure for emergency bladder drainage and can be performed by resident surgeons. The common complications associated with the procedure can be avoided with a few careful steps. PMID:23131233

Conservative management in ureteric hydronephrosis due to deep endometriosis: Could the levonorgestrel-intrauterine device be an option?

2017-07-01

Endometriosis can affect up to 10% of women of reproductive age, in a wide range of clinical presentations that vary from mild to severe or deep endometriosis. Deep endometriosis can affect the urinary tract in 1-5% to 15-25% cases. Even though deep endometriosis' surgeries are usually complex with higher rate of complications, conservative management is not always considered as an option because of its high failure rates. This paper describes two cases of deep endometriosis with ureteric involvement (hydronephrosis) treated conservatively with a double-pigtail stent plus a Levonorgestrel intrauterine device, after conservative surgery, who remained symptom free with no evidence of recurrence at 3 years follow-up, avoiding radical high-risk surgery. Impact statement Several treatments have been described for endometriosis. From a symptomatic perspective, conservative medical management has been proposed with a variable response. Concerning deep endometriosis (affecting the urinary or digestive tract), the definitive treatment has always been thought to be radical surgery. However, this can lead to several complications. To illustrate a possible more conservative approach this paper describes two cases of deep infiltrating endometriosis affecting the ureter, treated conservatively with a temporary pigtail ureter stent plus a Levonorgestrel intrauterine device. The management demonstrates that, in a selected population, conservative treatment solves the urinary disease avoiding the surgical complications and, what is more, improving patients' symptoms in a permanent way. Further prospective studies are needed to confirm whether the introduction of this management in clinical practice would reduce the need for surgery thereby, avoiding high-risk surgery and improving the success rate of conservative management.

Relatively little has been reported about destruction through brachytherapy of mucosa-perforating and extraluminary tumors with probable large vessel involvement causing major hemorrhagic or fistular complications. We report 12 patients subjected to laser and brachytherapy for centrally occluding lung cancer, whom we have periodically followed up from June 1986 until they died. Although all laser procedures were free from complications, necrotic cavitation in five cases, two of which were accompanied by large bronchoesophageal fistulas, and massive fatal hemoptysis occurred in six. Minor complications included radiation mucositis (two), noncritical mucosal scarring (two), and cough (four). Characteristics that will identify patients at riskmore » of developing fatal hemoptysis and fistulas should be better defined by imaging and endoscopic techniques. In such cases, modifying the protocol or using alternative procedures should be considered. Minor complications, such as cough, can be avoided by using topical steroid therapy (eg, beclomethasone dipropionate).« less

2016-07-01

Choanal atresia is rare in small animal veterinary medicine, and most cases are misdiagnosed and are actually a nasopharyngeal stenosis (NPS), which is frustrating to treat because of the high recurrence rates encountered after surgical intervention. Minimally invasive treatment options like balloon dilation (BD), metallic stent placement (MS), or covered metallic stent (CMS) placement have been met with success but are associated with various complications that must be considered. The most common complication with BD alone is stenosis recurrence. The most common complications encountered with MS placement is tissue in-growth, chronic infections and the development of an oronasal fistula. The most common complications with a CMS is chronic infections and the development of an oronasal fistula, but stricture recurrence is avoided. Copyright © 2016 Elsevier Inc. All rights reserved.

Passeri, Luis A.; Choi, James G.; Kaban, Leonard B.; Lahey, Edward T.

2016-01-01

Purpose To compare morbidity and mortality rates in obstructive sleep apnea (OSA) versus dentofacial deformity (DFD) patients undergoing equivalent maxillofacial surgical procedures. Patients and Methods Patients with OSA who underwent maxillomandibular advancement with genial advancement (MMA), at Massachusetts General Hospital Department of Oral and Maxillofacial Surgery, from December 2002 to June 2011, were matched to patients with DFD undergoing similar maxillofacial procedures during the same time period. They were compared with regards to demographic variables, medical comorbidities, perioperative management, intraoperative, early and late postoperative complications and mortality. Results A study group of 28 patients with OSA and a control group of 26 patients with DFD were compared. The patients with OSA were older (41.9±12.5 vs. 21.7±8.6years), had a higher ASA classification (2.0±0.5 vs. 1.3±0.6) and BMI (29.6±4.7 vs. 23.0±3.1kg/m2). They also had a greater number of medical comorbidities (2.4±2.3 vs. 0.7±1.0). More OSA than DFD patients had complications (28, 100% vs.19, 73%, p=0.003) and the total number of complications in the OSA group was higher (108 vs. 33, p<0.001). In the OSA group, 13.9% and in the DFD group 3.0% of the complications were classified as major. The absolute risk of a complication for the OSA group was 3.9 vs . 1.3 for the DFD group. The relative risk of complications in OSA compared to DFD was 3.0. No difference in mortality was found. Conclusions OSA patients were older, had more comorbidities and ultimately had a greater number of early, late, minor and major complications than those in the DFD group. The incidence of mortality in both groups was zero. MMA appears to be a safe procedure with regards to mortality but OSA patients should be counseled preoperatively regarding the relative increased risk of complications. PMID:27181624

Stroke is a major cause of death and other complications worldwide. In Saudi Arabia, stroke has become an emerging health issue leading to disability and death. However, stroke care including rehabilitation services, in Saudi Arabia lags behind developed countries. Stroke rehabilitation is an essential recovery option after stroke and should start as early as possible to avoid potential complications. The growing evidence on stroke rehabilitation effectiveness in different health care settings and outcome measures used widely are reviewed in this call to action paper. PMID:27744457

A 34-year-old man presenting with a left inguinal mass was diagnosed as having idiopathic multiple aneurysmal disease and pseudoaneurysm of a left superficial femoral artery. A stent-graft was successfully deployed percutaneously at the left superficial femoral artery pseudoaneurysm. Less invasive treatment should be used to avoid vascular complications in patients with idiopathic multiple aneurysmal disease, especially in those who have a progressive course or a history of prior complications after surgical repair.

A fatal trip with ecstasy: a case of 3,4-methylenedioxymethamphetamine/3,4- methylenedioxyamphetamine toxicity.

Since the late 1980s there have been a number of reports about the complications associated with using the designer drug 3,4-methylenedioxymethamphetamine (MDMA) or 'ecstasy'. Although this drug has been widely abused in the past, the potentially fatal complications have arisen recently mainly due to the circumstances of its use at all-night dance sessions or 'raves'. A combination of direct toxicity and strenuous physical exertion can lead to hyperthermia and its attendant complications. The following case illustrates some of the possible consequences following ingestion of 'ecstasy', and reiterates the importance of prompt recognition and treatment in preventing the development of irreversible sequelae.

The risk of surgical site infection (SSI) remains high after major reconstructive surgery of the head and neck. Clinical data regarding SSI in microsurgical tongue reconstruction are described at National Cancer Hospital in Japan, including discussions of unfavorable representative cases, the relationship between SSI and preoperative irradiation at Okayama University Hospital in Japan, and strategies for SSI control in head and neck reconstruction. Local complications are inevitable in patients undergoing reconstruction in the head and neck areas. The frequency of major complications can be decreased, and late postoperative complications can be prevented with the help of appropriate methods. Copyright © 2016 Elsevier Inc. All rights reserved.

Given the increasing popularity of dental implants, the number of failures due to late implant fracture is also expected to increase. Hence, the scope for prevention and management needs to be emphasized. The objective of this review article is to analyze the various causes of failure of dental implants due to implant fixture/abutment screw fractures and also to enumerate the management and the preventive options for these failures, thereby aiming to help the clinicians to properly plan the implant-supported prosthesis treatment by considering the important biomechanical aspects of this type of rehabilitation. The present review emphasizes the causes and management of technical complications and not the incidence of such complications. PMID:26668445

There is reluctance amongst many healthcare professionals to offer bariatric surgery to septuagenarians. There is only one study in the scientific literature specifically describing any experience with this group of patients and none that compares the outcomes in this group with younger patients. We retrospectively examined our prospective database to identify all those who were >70 years old at the time of bariatric surgery. This group was then compared with a matched (for sex, body mass index, surgical procedure, and time of surgery) cohort of younger (<60 year old) patients. Information was obtained from our database, case notes, hospital electronic records, by interviewing team members, and from general practitioners. A total of 10 septuagenarians were compared with 10 younger patients (mean age 41 years). There were one early complication and 1 late complication in the over 70 group as opposed to no early complication and 2 late complications in the younger group. There was no mortality or early reoperation in either group. Excess weight loss of 50.4, 67.4, and 74.0% in the >70 age group at 6, 12, and 24 months, respectively, was no different to 51.3, 70.8, and 73.9% in <60 year olds. The effect on the co-morbidity resolution was similar in the two groups. In carefully selected septuagenarians, bariatric surgery can be performed with safety and efficacy comparable to those <60 years old.

ABSTRACT Background: Previous studies on the influence of different types of attachment on grief responses have yielded contradictory outcomes. Little research has been conducted to identify the psychological processes that moderate the relationship between attachment representations and patterns of grief in disaster-related grief. Objective: The present study examines the effects of different attachment types on the grief responses of parents bereaved by loss of a child in a ferry accident, along with the moderating role of coping strategies. Methods: Bereaved parents (n = 81) completed self-report questionnaires evaluating attachment, coping strategies, complicated grief, and shame/guilt. We performed correlational analyses to examine the associations among variables. We also conducted hierarchical regression analyses and simple slope analyses to examine the moderation effects of coping strategies. Results: Anxious attachment was associated with severe shame/guilt, and avoidant attachment correlated with complicated grief. Anxious attachment was positively associated with all types of coping strategies, and avoidant attachment was negatively related to problem- and emotion-focused coping. The use of problem-focused coping strategies was a significant moderator of the relationship between the avoidant attachment dimension and shame/guilt. Avoidant attachment had a significant effect on shame/guilt in groups with a high level of problem-focused coping. In contrast, none of the coping strategies significantly moderated the relationship between anxious attachment and grief response. Conclusions: The results suggest that people with highly avoidant attachment might be overwhelmed by shame and guilt when they try to use problem-focused coping strategies. This finding suggests that grief interventions should be organized with consideration of individual differences in attachment representations. PMID:29372009

Do no harm--normal tissue effects

NASA Technical Reports Server (NTRS)

Hall, E. J.

2001-01-01

Radiation therapy confers enormous benefits that must be balanced against the possibilities for harm including late toxicity in normal tissues and radiation-induced second malignancies. A small percentage of patients experience severe late complications. The question is, do these late sequelae occur randomly, or are they confined to individuals who are genetically predisposed to radiosensitivity. Experiments with knockout mice and with patients demonstrate that individuals heterozygous for a number of genes appear to be radiosensitive. If radiosensitive patients were identified prospectively by genetic analysis, they could be spared the trauma of late sequelae. Several large studies have shown a statistically significant excess of radiation-induced malignancies in radiotherapy patients. Most second cancers are carcinomas, developing in the lining cells of the body often remote from the treatment site. Radiation-induced sarcomas appear only in the heavily irradiated areas. These are small in number but appear with a very high relative risk.

Distribution and characteristics of metamorphic belts in the south- eastern Alaska part of the North American Cordillera

The Cordilleran orogen in south-eastern Alaska includes 14 distinct metamorphic belts that make up three major metamorphic complexes, from east to west: the Coast plutonic-metamorphic complex; the Glacier Bay-Chichagof plutonic-metamorphic complex; and the Chugach plutonic-metamorphic complex. Each of these complexes is related to a major subduction event. The metamorphic history of the Coast complex is lengthy and is related to the Late Cretaceous collision of the Alexander and Wrangellia terranes and the Gravina overlap assemblage to the west against the Stikine terrane to the east. The metamorphic history of the Glacier Bay-Chichagof complex is relatively simple and is related to the roots of a Late Jurassic to late Early Cretaceous island arc. The metamorphic history of the Chugach is complicated and developed during and after the Late Cretaceous collision of the Chugach terrane with the Wrangellia and Alexander terranes. -from Authors

Existing standards for screening and management of late effects occurring in children who have undergone hematopoietic cell transplantation (HCT) include recommendations from pediatric cancer networks and consensus guidelines from adult-oriented transplantation societies applicable to all recipients of HCT. While these approaches have significant merit, they are not pediatric-HCT focused and they do not address post-HCT challenges faced by children with complex non-malignant disorders. In this article we discuss the strengths and weaknesses of current published recommendations and conclude that pediatric-specific guidelines for post-HCT screening and management would be beneficial to the long-term health of these patients and would promote late-effects research in this field. Our panel of late effects experts also provides recommendations for follow up and therapy of selected post-HCT organ and endocrine complications in pediatric patients. PMID:22248713

Anterior clinoidectomy is a difficult yet essential technique in skull base surgery. Two main techniques (extradural and intradural) with multiple modifications have been proposed to increase efficiency and avoid complications. In this study, the authors sought to develop a hybrid technique based on localization of the optic strut (OS) to combine the advantages and avoid the disadvantages of both techniques. Ten cadaveric specimens were prepared for surgical simulation. After a standard pterional craniotomy, the anterior clinoid process (ACP) was resected in 2 steps. The segment anterior to the OS was resected extradurally, while the segment posterior to the OS was resected intradurally. The proposed technique was performed in 6 clinical cases to evaluate its safety and efficiency. Anterior clinoidectomy was successfully performed in all cadaveric specimens and all 6 patients by using the proposed technique. The extradural phase enabled early decompression of the optic nerve while avoiding the adjacent internal carotid artery. The OS was drilled intradurally under direct visualization of the adjacent neurovascular structures. The described landmarks were easily identifiable and applicable in the surgically treated patients. No operative complication was encountered. A proposed 2-step hybrid technique combines the advantages of the extradural and intradural techniques while avoiding their disadvantages. This technique allows reduced intradural drilling and subarachnoid bone dust deposition. Moreover, the most critical part of the clinoidectomy-that is, drilling of the OS and removal of the body of the ACP-is left for the intradural phase, when critical neurovascular structures can be directly viewed.

Objective: The aim was to evaluate the parameters that were considered by Forensic Medicine in bile duct injury as well as the issues that the physicians were found to be faulty. Material and Methods: The following parameters were investigated in 21 files that were referred to Istanbul Forensic Medicine Institute with request of expert opinion between 2008–2012; expert decisions, patient’s age, gender, written patient consent, diagnosis, type of first surgery, surgical complications, timing of complication diagnosis within the scope of complication management, patient’s referral timing, troubleshooting procedures and mortality rate. Results: Physicians were found to be faulty in all files. The reason for physician fault was failure to show the necessary professional care and attention in one (4.7%) file, late recognition of injury and late transfer of the patient in 20 (95.3%) files. Written consent had not been obtained in any of the files. Thirteen patients were female (61.9%) and 8 (30.1%) were male, with a mean age of 43.3 years. Nineteen patients had cholelithiasis (90.4%), and two patients (9.5%) had a mass in the head of the pancreas. Cholecystectomy was performed laparoscopically in 15 patients (78.9%), and with open surgery in 4 patients (21.1%). The Whipple procedure was performed in two patients. The diagnosis was made during the operation in one patient (4.7%), and in the post-operative period in 20 patients (95.3%). The time to diagnosis after surgery was between 3–6 days. All of the patients had been referred to third level health care facilities. The timing of transfer was 1 day in the patient who was diagnosed during the operation, and ranged between 4–10 days in those who were diagnosed postoperatively. Reasons for late referral were delays related to pending test results in 12 patients, vague signs in 3 patients, and following-up patients with the thought that the biliary fistula will heal by itself in 5 patients. Mortality was not observed in any of the examined files. Conclusion: The issues where physicians were most frequently found to be faulty were failure to obtain written patient consent, late recognition of injury and late transfer of the patient.

Poly(l-lactide) (PLLA) is the structural material of the first clinically approved bioresorbable vascular scaffold (BVS), a promising alternative to permanent metal stents for treatment of coronary heart disease. BVSs are transient implants that support the occluded artery for 6 mo and are completely resorbed in 2 y. Clinical trials of BVSs report restoration of arterial vasomotion and elimination of serious complications such as late stent thrombosis. It is remarkable that a scaffold made from PLLA, known as a brittle polymer, does not fracture when crimped onto a balloon catheter or during deployment in the artery. We used X-ray microdiffraction to discover how PLLA acquired ductile character and found that the crimping process creates localized regions of extreme anisotropy; PLLA chains in the scaffold change orientation from the hoop direction to the radial direction on micrometer-scale distances. This multiplicity of morphologies in the crimped scaffold works in tandem to enable a low-stress response during deployment, which avoids fracture of the PLLA hoops and leaves them with the strength needed to support the artery. Thus, the transformations of the semicrystalline PLLA microstructure during crimping explain the unexpected strength and ductility of the current BVS and point the way to thinner resorbable scaffolds in the future.

New approach in partial cavopulmonary connection.

The development of pulmonary arteriovenous fistulas after bidirectional cavopulmonary operations, such as the bidirectional Glenn shunt and Kawashima's procedure, has raised concern. Development of these fistulas, which are more frequent than initially thought, can represent a limiting factor in the late outcome of these patients and may even limit the indication for these types of surgery. Whether the fistulas can be reversed by transforming the surgical procedures has yet to be established. In the hope of avoiding this kind of complication, thought to be caused by the lack of passage of a hypothetical hepatic factor through the pulmonary circulation, we have developed an inverted type of bidirectional cavopulmonary connection in which the blood coming from the liver perfuses immediately both lungs. This is made possible by shunting via an intra-atrial tunnel the blood from the superior caval vein directly to the left atrium, and the blood from the inferior caval vein to the right branch of the pulmonary trunk (keeping its bifurcation intact). We describe findings in two patients undergoing successful surgery with this technique. Serial follow-up with contrast echocardiography did not show evidence of arteriovenous pulmonary fistulas. Despite our numbers being small, and the time of follow-up being limited, we believe that it is important to document these and similar cases.

Half forehead reconstruction with a single rotational scalp flap for dermatofibrosarcoma protuberans treatment

PubMed Central

2012-01-01

Background Dermatofibrosarcoma protuberans (DFSP) is a soft tissue neoplasm of intermediate to low-grade malignancy. Although metastasis rarely occurs, DFSP has a locally aggressive behavior with a high recurrence rate. In the head and neck area, resection involving a wide margin of healthy tissue can be difficult because of functional and cosmetic considerations. We describe a novel reconstructive method for half forehead defects with an innovative single local wide scalp flap following excision of DFSP with a 3 cm margin of healthy tissue. Methods Two patients underwent wide resection of forehead DFSP and reconstruction with a single rotational scalp flap. The scalp flap blood supply was provided from three main vessels: the superficial temporal artery, occipital artery and posterior auricular artery. Results No early or late complications were observed in either patient with no local recurrence after 18 months of follow-up. The donor area could be closed primarily in both cases and the flaps survived completely. Conclusion This innovative technique allowed a radical excision of forehead DFSP with sufficient healthy margins, thus potentially decreasing tumor recurrence rate. Reconstruction was achieved avoiding microsurgery, skin expanders and large skin grafts. Moreover, all main reconstructive criteria, such as functional and cosmetic tissue characteristics, were completely fulfilled. PMID:22559860

Bile duct injury: management options during and after gallbladder surgery.

PubMed

Vecchio, R; MacFadyen, B V; Ricardo, A E

1998-06-01

Proper management of iatrogenic bile duct injuries is mandatory to avoid immediate or late life threatening sequelae. Results of surgery depend mainly on the type of injury, the detection of the injury, and the timing of the surgery. Lesions detected during cholecystectomy should be repaired immediately, preferably with an end-to-side biliary anastomosis, a Roux-en-Y bilio-enteric anastomosis, or by the insertion of a T-tube. Bile duct injuries detected in the postoperative phase require a multidisciplinary approach and an algorithm for treatment of each type of lesion is proposed. In bile peritonitis with biliary obstruction and/or transection and in tight long strictures, which develop several months after cholecystectomy, a Roux-en-Y hepatico-jejunostomy is the most commonly performed operation. Other surgical techniques include a "mucosal graft" procedure and intrahepatic biliary enteric anastomoses, which may be required in difficult high-biliary lesions. Endoscopy and/or interventional radiology offer the best treatment options in bile duct leaks and in short ductal strictures that involve less than 50% of the bile duct lumen. In these injuries, surgical management should be performed only in the failure of nonsurgical methods. Because these lesions involve complicated biliary surgery, therapeutic endoscopy, and interventional radiology, treatment should be performed where there is expertise in all three areas.

Boxing-acute complications and late sequelae: from concussion to dementia.

2010-11-01

Boxing has received increased public attention and acceptance in recent years. However, this development has not been accompanied by a critical discussion of the early and late health complications. We selectively review recent studies on the acute, subacute, and chronic neuropsychiatric consequences of boxing. Cerebral concussions ("knock-outs") are the most relevant acute consequence of boxing. The number of reported cases of death in the ring seems to have mildly decreased. Subacute neuropsychological deficits appear to last longer than subjective symptoms. The associated molecular changes demonstrate neuronal and glial injury correlated with the number and severity of blows to the head (altered total tau, beta-amyloid, neurofilament light protein, glial fibrillary acidic protein, and neuron-specific enolase). The risk of a punch-drunk syndrome (boxer's dementia, dementia pugilistica) as a late effect of chronic traumatic brain injury is associated with the duration of a boxer's career and with his earlier stamina. There are similarities (e.g. increased risk with ApoE4-polymorphism, beta-amyloid pathology) and differences (more tau pathology in boxers) compared with Alzheimer's disease. Protective gear has led to a remarkable reduction of risks in amateur boxing. Similar measures can also be used in professional boxing, but may decrease the thrill, which does appeal to many supporters.

Trans-catheter aortic valve implantation (TAVI) technology is rapidly evolving, with 412 procedures having been performed at our institution. Herein, we report a complete, prospective analysis of complications occurring during transvascular and trans-apical implantations with two different prostheses. Between June 2007 and June 2010, 412 patients (258 female, mean age 80.3±7.2 years, logistic EuroSCORE (European System for Cardiac Operative Risk Evaluation) 20.2%±13.0%) underwent TAVI through either a retrograde (n=252 transfemoral, n=28 transaxillary, and n=5 transaortic) or antegrade (n=127 trans-apical) approach at our institution. The trans-apical access was chosen only in cases where transvascular implantation was not possible. As many as 283 CoreValve and 129 Edwards Sapien prostheses were implanted. Thirty-day survival was 90.9%. Vascular complications occurred in 42 patients (10.2%). In four patients, lethal aortic root (n=3) or abdominal (n=1) aortic rupture occurred. Pericardial effusion developed in 53 patients (12.8%), which resulted in cardiac tamponade in 12 patients (2.9%). Twenty-three patients (5.6%) with valve malplacement were treated interventionally. In five patients (1.2%), emergency institution of cardiopulmonary bypass was required during the procedure for temporary support; all patients survived. Seventeen patients underwent re-intervention on the catheter valve (4.1%). With growing experience, complications with TAVI may be avoided by proper patient selection and skillful management. Other complications, when they occur, require a specific treatment algorithm to avoid delay in decision making. A considerable number of complications after TAVI require surgical treatment. Therefore, the ideal environment for TAVI procedures is a hybrid operating room, where a multidisciplinary team of surgeons, cardiologists, and anesthesiologists is best fitted to meet the current needs associated with TAVI technology. A reduction in complications was seen after 300 cases. This finding attests to the complexity of the procedure in addition to the experience required to reduce the incidence of complications.

Urinary tract infections (UTI) are the most common bacterial infections involving lower (cystitis, prostatitis) or upper (pyelonephritis, renal abscess, perinephric abscess) urinary tract. Differentiation of complicated and uncomplicated UTI is usually based on the presence of structural or functional urinary tract abnormalities, which can increase the risk of treatment failure and development of serious complications. Factors that increase the risk are foreign bodies, stones, obstruction, neurogenic bladder, kidney transplantation, immunosuppression, and pregnancy. Complicated UTI includes a spectrum of conditions that increase the risk of treatment failure, as well as of serious complications such as bacteremia and sepsis, perinephric abscess, renal impairment and emphysematous pyelonephritis. To avoid the potentially devastating outcomes, appropriate diagnostic procedures, antibiotic and surgical treatment, and appropriate follow-up are required. The incidence of complicated UTI will grow in the future due to general aging of the population, increasing incidence of diabetes, and ever growing number of immunocompromised and immunosuppressed patients. It is of key importance to recognize complicated UTI on time, and treat it wisely and aggressively to reduce duration of the disease and the risk of antibiotic resistance.

Bariatric surgery is now frequently proposed for the treatment of morbid or complicated obesity since the introduction of minimally invasive laparoscopic anti-obesity operations such as the adjustable silicone gastric binding gastroplasty. However this reversible procedure in not always as safe as presumed and the results in weight loss may be sometimes disappointing. Side effects are common and early or late complications occured in more than 20% out of the patients. They are favoured by post operative eating disorders. Nutritional consequences are probably underestimated and are not limited to uncomfortable digestive symptoms. Some deficiencies in micronutriments have been described. The worsening of previous eating disorders or psychosocial abnormalities are not seldom. Gastroplasty is not an harmless procedure. A good selection in patients, a regular follow up, nutritional advices and psychosocial management by a multidisciplinar team are required to reduce complications after gastroplasty.

The aim of this study was to compare early weightbearing and range of motion (ROM) to nonweightbearing and immobilization in a cast after surgical fixation of unstable ankle fractures. Multicentre randomized controlled trial. Two-level one trauma centers. One hundred ten patients who underwent open reduction and internal fixation of an unstable ankle fracture were recruited and randomized. One of 2 rehabilitation protocols: (1) Early weightbearing (weightbearing and ROM at 2 weeks, Early WB) or (2) Late weightbearing (nonweightbearing and cast immobilization for 6 weeks, Late WB). The primary outcome measure was time to return to work (RTW). Secondary outcome measures included: ankle ROM, SF-36 heath outcome scores, Olerud/Molander ankle function score, and rates of complications. There was no difference in RTW. At 6 weeks postoperatively, patients in the Early WB group had significantly improved ankle ROM (41 vs. 29, P < 0.0001); Olerud/Molander ankle function scores (45 vs. 32, P = 0.0007), and SF-36 scores on both the physical (51 vs. 42, P = 0.008) and mental (66 vs. 54, P = 0.0008) components. There were no differences with regard to wound complications or infections and no cases of fixation failure or loss of reduction. Patients in the Late WB group had higher rates of planned/performed hardware removal due to plate irritation (19% vs. 2%, P = 0.005). Given the convenience for the patient, early improved functional outcome, and the lack of an increased complication rate, we recommend early postoperative weightbearing and ROM in patients with surgically treated ankle fractures.

Anticoagulation is routinely administered to all trauma patients owing to the high incidence of venous thromboembolism (VTE). However, the timing of administration of anticoagulation is not clearly defined when patients have blunt spleen or liver injuries because of the perceived risk of hemorrhage with early administration. A retrospective chart review was performed of all blunt trauma patients who sustained blunt liver and/or spleen injuries during the 5-year period from 2007 to 2011. Data were collected for all patients managed with nonoperative therapy for these injuries while also receiving routine prophylactic anticoagulation with low molecular-weight heparin. Patients were categorized based on the initiation of enoxaparin therapy after injury: early (<48 hours), intermediate (48 to 72 hours), and late (>72 hours). Primary and secondary outcomes were designated as need for operative or radiologic intervention secondary to spleen or liver hemorrhage, number of transfusions, and incidence of VTE. Three hundred and twenty-eight patients were included. There were no enoxaparin-related hemorrhagic complications or hemorrhage necessitating operative intervention. Patients in the early, intermediate, and late groups received an average of .9, .93, and 1.55 units of blood, respectively. There was 1 pulmonary embolism in the early group, and there were 6 VTE complications in the late group (3 deep venous thromboses and 3 pulmonary embolisms). There are currently no standards for the initiation of prophylactic anticoagulation in trauma patients with blunt liver and spleen injuries. Early administration may be safe and reduce the incidence of thrombotic complications in patients with blunt spleen and liver injuries. Prospective studies in this area are warranted.

To ensure an appropriate follow-up of childhood cancer survivors and reducing late liver complications, the need for comprehensive and accurate information is presented. We evaluate the risk of liver diseases in a large childhood cancer survivor cohort. We included all 1-year survivors of childhood cancer treated in the five Nordic countries. A Cox proportional hazards model was used to estimate hospitalisation rate (hazard) ratios (HRs) for each liver outcome according to type of cancer. We used the risk among survivors of central nervous system tumour as internal reference. With a median follow-up time of 10 years, 659 (2%) survivors had been hospitalised at least once for a liver disease. The risk for hospitalisation for any liver disease was high after hepatic tumour (HR = 6.9) and leukaemia (HR = 1.7). The Danish sub-cohort of leukaemia treated with haematopoietic stem cell transplantation had a substantially higher risk for hospitalisation for all liver diseases combined (HR = 3.8). Viral hepatitis accounted for 286 of 659 hospitalisations corresponding to 43% of all survivors hospitalised for liver disease. The 20-year cumulative risk of viral hepatitis was 1.8% for survivors diagnosed with cancer before 1990 but only 0.3% for those diagnosed after 1990. The risk of liver disease was low but significantly increased among survivors of hepatic tumours and leukaemia. Further studies with focus on the different treatment modalities are needed to further strengthen the prevention of treatment-induced late liver complications. © 2017 UICC.

Long-term complications after hematopoietic cell transplantation (HCT) have been studied in detail. Although virtually every organ system can be adversely affected after HCT, the underlying pathophysiology of these late effects remain incompletely understood. This article describes our current understanding of the pathophysiology of late effects involving the gastrointestinal, renal, cardiac, and pulmonary systems, and discusses post-HCT metabolic syndrome studies. Underlying diseases, pretransplantation exposures, transplantation conditioning regimens, graft-versus-host disease, and other treatments contribute to these problems. Because organ systems are interdependent, long-term complications with similar pathophysiologic mechanisms often involve multiple organ systems. Current data suggest that post-HCT organ complications result from cellular damage that leads to a cascade of complex events. The interplay between inflammatory processes and dysregulated cellular repair likely contributes to end-organ fibrosis and dysfunction. Although many long-term problems cannot be prevented, appropriate monitoring can enable detection and organ-preserving medical management at earlier stages. Current management strategies are aimed at minimizing symptoms and optimizing function. There remain significant gaps in our knowledge of the pathophysiology of therapy-related organ toxicities disease after HCT. These gaps can be addressed by closely examining disease biology and identifying those patients at greatest risk for adverse outcomes. In addition, strategies are needed for targeted disease prevention and health promotion efforts for individuals deemed at high risk because of their genetic makeup or specific exposure profile.

Hematopoietic stem cell transplantation (HSCT) is currently the only curative treatment for acute leukemia. As HSCT improves the long-term survival, it is necessary to assess the late-onset complications affecting the quality of life following HSCT. The study included 122 patients (65 male, 57 female) with leukemia (72 AML and 50 ALL) who received transplants from fully- matched siblings, unrelated donors and unrelated cord blood donors between February 2013 and August 2014 in Shariati Hospital. All study participants were over 18 years of age and had the minimum and maximum survival of 2 and 5 years, respectively. Patients who received HLA-haploidentical SCT were excluded from the study. All allogeneic recipients received busulfan and cyclophosphamide as conditioning regimen. Nobody received TBI-based conditioning regimen in this study. Patients were evaluated for cardiovascular, vision, psychological, endocrine, fertility problems and secondary malignancies one year after transplantation. Results : Data were analyzed using SPSS 15.0. Mitral and tricuspid regurgitation (TR/MR) were the most common cardiac complications (n=12, 10.5%).Thirty-nine percent of patients had psychological problems, especially depression (34%). Cataract was observed in 13% of patients and 34% complained of dry eye. Symptomatic pulmonary changes were found in 13 patients (10.6%). None of the HSCT survivors had experienced fertility before study entry. According to LH and FSH levels, 15% and 9% of females had ovarian failure, respectively. Testosterone level was less than normal in 49(84%) men and, according to their FSH and LH level, 20 (41%) had secondary hypogonadism and 29 (59%) had primary gonadal dysfunction. The results showed that patients who received Bu/Cy conditioning regimen experienced fewer late side effects such as cataract formation and hypothyroidism, compared to previous studies using TBI-based conditioning regimen.

The need for colonoscopy is common among diabetic patients. However, there are no standards per se for bowel preparation in patients with type 2 diabetes. In this study, we evaluated the efficacy, safety, and tolerability of sodium phosphate (NaP), and the quality of bowel cleansing in relation to glycemic control and late complications. A total of 50 consecutive type 2 diabetic patients and 50 non-diabetic patients underwent bowel preparation by NaP. Fasting blood glucose, sodium (Na), potassium (K), calcium (Ca), phosphorus (P), magnesium, and creatinine levels were measured on the procedure day. Patients were given a tolerability questionnaire regarding symptoms. With regard to bowel preparation quality, optimal bowel cleansing was achieved in 35 (70%) diabetic and 47 (94%) non-diabetic patients (P = 0.002). Abdominal pain or discomfort during and an hour after the procedure was similar in both groups (P >0.05). The changes in Na, K, Ca, P and creatinine levels after NaP use did not reach statistical significance between the groups (P >0.05). In the diabetic patients, there was a significant correlation between the quality of bowel cleansing and mean age, duration of diabetes mellitus, level of hemoglobin A1c (HbA1c), fasting blood glucose level, and diabetic late complications (P <0.05). These data suggest that NaP is safe and tolerable in diabetic patients, but the quality of bowel cleansing is worse than in non-diabetic patients. These observations support the concept that the quality of bowel cleansing in those with type 2 diabetes is closely related to the duration and regulation of the disease and the presence of late complications.

We reviewed the outcome of the 10 patients (13 eyes) with localized, biopsy-proven, low-grade lymphoma of the conjunctiva treated at our Department between 1988 and 1997. All patients were treated by beta-ray brachytherapy using a bidirectional 90Sr-90Y ophthalmic applicator (Applicator SIA 2, Amersham plc). Total doses, prescribed at the surface of the applicator, varied between 40 Gy and 80 Gy. With a median follow-up of 78 months (range: 14 to 146 months), seven patients remained with no evidence of relapse (67.5% 10 year disease free survival). Local control was achieved in 10 out of 13 eyes (76.9%). Two of the three local relapses were marginal. One of these three patients also developed a metachronous lymphoma in the contralateral conjunctiva. These three patients underwent a second course of brachytherapy with 90Sr/90Y and remained free of second relapse 109, 68 and 33 months after salvage therapy. No cases of systemic relapse were observed. Late (LENT-SOMA) complications were of grade 2 in five eyes, of grade 3 in one eye and of grade 4 in one eye. Late complications of grade 2 or higher were observed in one out of five patients (20%) treated with doses lower or equal to 50 Gy and in six out of eight patients (75%) treated with doses higher than 50 Gy (P=0.086). Our data indicates that beta-ray brachytherapy was ultimately able to control most conjunctival lymphomas but carried a risk of late complications and marginal relapses that was possibly higher than the rates reported for other radiotherapy techniques.

Variations on the endoscopic transsphenoidal approach present unique surgical techniques that have unique effects on surgical outcomes, extent of resection (EOR), and anatomical complications. To analyze the learning curve and perioperative outcomes of the 3-hand endoscopic endonasal mononostril transsphenoidal technique. Prospective case series and retrospective data analysis of patients who were treated with the 3-hand transsphenoidal technique between January 2007 and May 2015 by a single neurosurgeon. Patient characteristics, preoperative presentation, tumor characteristics, operative times, learning curve, and postoperative outcomes were analyzed. Volumetric EOR was evaluated, and a logistic regression analysis was used to assess predictors of EOR. Two hundred seventy-five patients underwent an endoscopic transsphenoidal surgery using the 3-hand technique. One hundred eighteen patients in the early group had surgery between 2007 and 2010, while 157 patients in the late group had surgery between 2011 and 2015. Operative time was significantly shorter in the late group (161.6 min) compared to the early group (211.3 min, P = .001). Both cohorts had similar EOR (early group 84.6% vs late group 85.5%, P = .846) and postoperative outcomes. The learning curve showed that it took 54 cases to achieve operative proficiency with the 3-handed technique. Multivariate modeling suggested that prior resections and preoperative tumor size are important predictors for EOR. We describe a 3-hand, mononostril endoscopic transsphenoidal technique performed by a single neurosurgeon that has minimal anatomic distortion and postoperative complications. During the learning curve of this technique, operative time can significantly decrease, while EOR, postoperative outcomes, and complications are not jeopardized.

The Influence of Depression on Cognitive Control: Disambiguating Approach and Avoidance Tendencies.

2015-01-01

Dysfunctions of approach and avoidance motivation play an important role in depression, which in turn may affect cognitive control, i.e., the ability to regulate thoughts and action to achieve internal goals. We use a novel experimental paradigm, i.e. a computer simulated driving-task, to study the impact of depression on cognitive control by measuring approach and avoidance actions in continuous time. In this task, 39 subjects with minimal to severe depression symptoms were instructed to use a joystick to move a virtual car as quickly as possible to a target point without crossing a stop-sign or crashing into a wall. We recorded their continuous actions on a joystick and found that depression 1) leads to further stopping distance to task target; and 2) increases the magnitude of late deceleration (avoidance) but not early acceleration (approach), which was only observed in the stop-sign condition. Taken together, these results are consistent with the hypothesis that depressed individuals have greater avoidance motivation near stopping target, but are minimally affected by approach motivation.

To determine rates of complications after newborn circumcision by performing a retrospective chart review of patients circumcised at a well-baby nursery, neonatal intensive care units (NICU), and special care nursery (SCN) from 2007 to 2012. A total of 5129 babies (73%) were circumcised at the well-baby nursery and 1909 babies (27%) at the NICU and SCN. Forty-seven patients (0.67%, 95% CI 0.49% to 0.89%) had circumcision-related complications: 5 (0.07%) patients with acute and 42 (0.6%) with late complications. Babies in the NICU/SCN had increased odds of complication (OR 4.00, 95% CI 2.23 to 7.19) compared with those in well-baby nursery. There were increased odds of complications in babies with Caucasian ethnicity (OR 2.60, 95% CI 1.48 to 4.89) compared with African American babies and in babies with private insurance (OR 4.0, 95% CI 2.1 to 7.5) compared with nonprivate insurance. The rates of complications after newborn circumcisions were low. Babies in the NICU/SCN had increased odds of complication. © The Author(s) 2015.

To identify preinjury coping profiles among adults with uncomplicated mild traumatic brain injury (mTBI) and complicated mTBI and to determine whether preinjury coping profiles contribute to the prediction of emotional functioning and quality of life (QOL) 3 months post-mTBI. One hundred eighty-seven persons with medically documented mTBI (uncomplicated mTBI, n = 89; complicated mTBI, n = 98) were recruited from the emergency center of a level I trauma center and followed in community 3 months post-mTBI. The Ways of Coping Questionnaire was administered within 2 weeks of injury. Cluster analysis was used to group participants on basis of their preinjury use of problem-focused and avoidant coping strategies. The Brief Symptom Inventory and the 36-item Short-Form Health Survey were administered 3 months postinjury. Cluster analysis distinguished 3 distinct preinjury coping profiles that were differentially associated with outcomes. Participants who used avoidant coping showed the worse emotional functioning and QOL outcomes, although this cluster also reported high usage of problem-focused strategies. Preinjury coping profiles explained a significant proportion of the variance in depression, anxiety, and mental health QOL at 3 months postinjury beyond that accounted for by demographic characteristics and mTBI severity. Cluster analysis holds practical value in illustrating the pattern of coping strategies used by person with uncomplicated and complicated mTBI. It appears worthwhile to address coping in future trials of interventions that are aimed at improving emotional functioning after mTBI.

Linked shoulder replacement: current design problems and a new design proposal.

Mohammed, Ali Abdullah; Frostick, Simon Peter

2016-04-01

Totally constrained shoulder replacement with linked components is one of the surgical options in post-tumor resection shoulder reconstruction or in complex shoulder revision operations. In this paper, we intend to shed light on such an implant design, which provides a linked constrained connection between the humeral head and the glenoid, and to show some immediate postoperative complications, implant progression to decrease the chances of implant mechanical postinsertion failure, and a new design proposal. In our center, we use the linked prosthesis in complex revision situations; however, there have been some complications, which could be attributed mainly to the engineering and the implant design, and hence potentially avoidable by making a different design to cover for those mechanical issues. Two such complications are described in this paper. Early revisions after linked shoulder replacement implantation were needed in two occasions due to implant disconnection: one of them was due to dislodgement from the native glenoid, and the second one was due to the disengagement of the ringlet which secures the linkage mechanism between the humeral head and the implanted glenoid shell. There is a need for a more stable design construct to avoid the reported complications that needed early revision surgeries. The new design proposed is an attempt to help providing a better and more stable implant to decrease the chances of revision in those complex situations where the patient already had many major operations, and working to increase the durability of the implant is crucial.

Eighty-three cases of tracheopleuropulmonary injuries complicating enteral tube feeding are analyzed to identify the patterns of injury, and precipitating factors and ways to avoid them. Six new cases observed by the authors and 77 other cases cited in British literature between 1976 and 1987 are presented. In recent years, reports of this complication have been increasing, apparently in a geometrical progression: 8%, 18%, and 74% were reported between 1976 to 1979, 1980 to 1983, and 1984 to 1987, respectively. Sixty-one percent occurred in patients aged 60 years or older. Most of the patients (84%) were seriously ill, which compounded their complications. Seventy-four percent of all injuries were committed by house staff; the narrow bore tube with guide wire was used in 77% of cases. Less than reliable methods were used to confirm tube position in most instances. The presence of cuffed endotracheal tubes did not offer protection. The patients on mechanical ventilation tended to deteriorate if they developed a pneumothorax once the malpositioned tubes were removed. Of the cases reviewed for this report, 18 deaths occurred; 72% being directly related to the tube injuries. Lack of awareness, inadequate confirmatory methods, and insufficient supervision accounted for most of these preventable complications. Educating house/nursing staff in the use of the new tubes, closer supervision, and the application of equal measures of care and caution as employed in other invasive and potentially dangerous procedures are recommended to avoid disastrous outcome.

Zeitoun, Rania; Hussein, Manar

2017-11-01

To reach a practical approach to interpret MDCT findings in post-operative spine cases and to change the false belief of CT failure in the setting of instruments secondary to related artefacts. We performed observational retrospective analysis of premier, early and late MDCT scans in 68 post-operative spine patients, with emphasis on instruments related complications and osseous fusion status. We used a grading system for assessment of osseous fusion in 35 patients and we further analysed the findings in failure of fusion, grade (D). We observed a variety of instruments related complications (mostly screws medially penetrating the pedicle) and osseous fusion status in late scans. We graded 11 interbody and 14 posterolateral levels as osseous fusion failure, showing additional instruments related complications, end plates erosive changes, adjacent segments spondylosis and malalignment. Modern MDCT scanners provide high quality images and are strongly recommended in assessment of the instruments and status of osseous fusion. In post-operative imaging of the spine, it is essential to be aware for what you are looking for, in relevance to the date of surgery. Advances in knowledge: Modern MDCT scanners allow assessment of instruments position and integrity and osseous fusion status in post-operative spine. We propose a helpful algorithm to simplify interpreting post-operative spine imaging.

Esophageal replacement in children: Challenges and long-term outcomes.

Replacement of a nonexistent or damaged esophagus continues to pose a significant challenge to pediatric surgeons. Various esophageal replacement grafts and techniques have not produced consistently good outcomes to emulate normal esophagus. Therefore, many techniques are still being practiced and recommended with no clear consensus. We present a concise literature review of the currently used techniques and with discussions on the advantages and anticipated morbidity. There are no randomized controlled pediatric studies to compare different types of esophageal replacements. Management and graft choice are based on geographical and personal predilections rather than on any discernible objective data. The biggest series with long-term outcome are reported for gastric transposition and colonic replacement. Comparison of different studies shows no significant difference in early (graft necrosis and anastomotic leaks) or late complications (strictures, poor feeding, gastro-esophageal reflux, tortuosity of the graft, and Barrett's esophagus). The biggest series seem to have lower complications than small series reflecting the decennials experience in their respective centers. Long-term follow-up is recommended following esophageal replacement for the development of late strictures, excessive tortuosity, and Barrett's changes within the graft. Once child overcomes initial morbidity and establishes oral feeding, long-term consequences and complications of pediatric esophageal replacement should be monitored and managed in adult life.

We examined the clinical significance of duodenogastric regurgitation (DGR) as a late complication in the long-term follow-up after hepaticoduodenostomy (HD) as a reconstruction surgery for congenital biliary dilatation (CBD). Seventeen patients with CBD were retrospectively analyzed for late complications (mean follow-up, 16.8 years). All patients had undergone total resection of the extrahepatic bile duct followed by HD. DGR was identified using endoscopic examination, intraluminal bile monitoring, and liver scanning. DGR was found in all 17 patients by endoscopic examination and intraluminal bile monitoring. Fourteen of the 17 (82.4%) patients with DGR had experienced abdominal symptoms since a mean of 6.9 years postoperatively. Liver scanning also revealed apparent DGR in all 14 symptomatic patients. We converted 7 of the 14 patients to hepaticojejunostomy reconstruction at a mean of 13.0 years after the initial excisional surgery. Their symptoms were completely relieved postoperatively. DGR is an important complication after HD. Examination of patients for the development of DGR is an essential part of long-term follow-up in patients with CBD who have undergone HD as a reconstruction surgery. Conversion surgery is recommended in patients with DGR accompanied by long-term abdominal symptoms. Level IV. Copyright © 2017 Elsevier Inc. All rights reserved.

Partial Red Blood Cell Exchange in Children and Young Patients with Sickle Cell Disease: Manual Versus Automated Procedure.

The benefits of manual versus automated red blood cell exchange have rarely been documented and studies in young sickle cell disease patients are scarce. We aim to describe and compare our experience in these two procedures. Young patients (≤ 21 years old) who underwent manual- or automated-red blood cell exchange for prevention or treatment of sickle cell disease complications were included. Clinical, technical and hematological data were prospectively recorded and analyzed. Ninety-four red blood cell exchange sessions were performed over a period of 68 months, including 57 manual and 37 automated, 63 for chronic complications prevention, 30 for acute complications and one in the pre-operative setting. Mean decrease in sickle hemoglobin levels was higher in automated-red blood cell exchange (p < 0.001) and permitted a higher sickle hemoglobin level decrease per volume removed (p < 0.001), while hemoglobin and hematocrit remained stable. Ferritin levels on chronic patients decreased 54%. Most frequent concern was catheter outflow obstruction on manual-red blood cell exchange and access alarm on automated-red blood cell exchange. No major complication or alloimunization was recorded. Automated-red blood cell exchange decreased sickle hemoglobin levels more efficiently than manual procedure in the setting of acute and chronic complications of sickle cell disease, with minor technical concerns mainly due to vascular access. The threshold of sickle hemoglobin should be individualized for clinical and hematological goals. In our cohort of young patients, the need for an acceptable venous access was a limiting factor, but iron-overload was avoided. Automated red blood cell exchange is safe and well tolerated. It permits a higher sickle hemoglobin removal efficacy, better volume status control and iron-overload avoidance.

To study the epidemiology, diagnosis, treatment strategies and perinatal outcomes of gestational syphilis. We performed a retrospective study of 94 pregnant women with syphilis whose gestation and delivery were monitored in a Department of Obstetrics from 2002 to 2010 among a total of 85,806 births of women without syphilis in the same period. The prevalence of gestational syphilis was 0.11%. Most of the women were foreign and the most prevalent type was late latent syphilis. Only 57 patients underwent right treatment despite adequate prescription. Maternal complications were confirmed in 31 pregnant women and 16 cases had fetal complications. We diagnosed 4 cases of neonatal syphilis, 3 of them with syphilitic meningitis, whose mothers had not completed the treatment correctly. The implementation of a mandatory syphilis serology in the pregnancy has enabled us to diagnose many cases of late latent syphilis. The successful completion of treatment must be ensured to prevent vertical transmission. Copyright © 2012 Elsevier España, S.L. All rights reserved.

Small-bowel volvulus in late pregnancy due to internal hernia after laparoscopic Roux-en-Y gastric bypass.

Naef, Markus; Mouton, Wolfgang G; Wagner, Hans E

2010-12-01

Internal hernias are a specific cause of acute abdominal pain and are a well-known complication after laparoscopic Roux-en-Y gastric bypass for morbid obesity. Although internal hernias are a rare cause of intestinal obstruction, they may evolve towards serious complications, such as extensive bowel ischemia and gangrene, with the need for bowel resection and sometimes for a challenging reconstruction of intestinal continuity. The antecolic position of the Roux limb is associated with a decrease in the incidence of small-bowel obstruction and internal hernias. The best prevention of the formation of these hernias is probably by closure of potential mesenteric defects at the initial operation with a non-absorbable running suture. We present a patient in late pregnancy with a small-bowel volvulus following laparoscopic Roux-en-Y gastric bypass for morbid obesity and discuss the available literature. For a favorable obstetric and neonatal outcome, it is crucial not to delay surgical exploration and an emergency operation usually is mandatory.

Epidermal inclusion cysts are benign lesions that can develop in any part of the body. However, the finding of an epidermal inclusion cyst in the penis is rare. The aim of this article was to present the management of a case of a penile epidermal inclusion cyst that occurred because of late complications of a penile girth enhancement surgery. A 52-year-old man presented with a painless, slowly growing mass in the penis, which was first noted after a penile girth enhancement surgery 20 years ago. A cystic mobile mass about 2 cm in depth was found surrounding the coronal sulcus. Excision of the mass was performed for diagnosis and treatment. There was no communication with the urethra. The pathological diagnosis was an epidermal inclusion cyst of the penis. A penile epidermal inclusion cyst in adult men is rare. It can develop after an inadequate procedure for penile girth enhancement, and should be treated by complete resection.

To present a case of a late, deep stromal scar in a 22-year-old patient with forme fruste keratoconus who underwent combined corneal cross-linking and photorefractive keratectomy (PRK). Topography-guided corneal cross-linking combined with corneal PRK (without complications) was performed in both eyes with a delay of 2 weeks between each eye. At the 5-month postoperative examination of the right eye, a localized corneal haze was circumscribed to the posterior deep stroma, signifying a decrease of visual acuity. However, this improved partially and temporarily when treated with topical corticoids during 2 years of follow-up and then reoccurred, affecting the corrected distance visual acuity. To the authors' knowledge, this is the first documented, clinical case presenting a deep stromal affectation without endothelial decompensation and visual acuity affectation as a postoperative complication following topography-guided PRK and corneal cross-linking.

Photodynamic Therapy (PDT) is a non-invasive treatment successfully used for neoplastic, inflammatory and infectious skin diseases. One of its strengths is represented by the high safety profile, even in elderly and/or immuno-depressed subjects. PDT, however, may induce early and late onset side effects. Erythema, pain, burns, edema, itching, desquamation, and pustular formation, often in association with each other, are frequently observed in course of exposure to the light source and in the hours/days immediately after the therapy. In particular, pain is a clinically relevant short-term complication that also reduces long-term patient satisfaction. Rare complications are urticaria, contact dermatitis at the site of application of the photosensitizer, and erosive pustular dermatosis. Debated is the relationship between PDT and carcinogenesis: the eruptive appearance of squamous cell carcinoma (SCC) in previously treated areas has been correlated to a condition of local and/or systemic immunosuppression or to the selection of PDT-resistant SCC. Here we review the literature, with particular emphasis to the pathogenic hypotheses underlying these observations. PMID:29382133

Tuberculosis-associated Fibrosing Mediastinitis: Case Report and Literature Review.

PubMed

Tan, Ronald; Martires, Joanne; Kamangar, Nader

2016-01-01

Fibrosing mediastinitis is a rare condition defined by the presence of fibrotic mediastinal infiltrates that obliterate normal fat planes. It is a late complication of a previous granulomatous infection, such as histoplasmosis or tuberculosis (TB). Due to its rarity, fibrosing mediastinitis is often under-recognized, and the clinical presentation is variable and dependent on the extent of infiltration or encasement of structures within the mediastinum. We present a case of fibrosing mediastinitis in a man with a prior history of TB, who presented with progressive dyspnea and was found to have chronic mediastinal soft tissue opacities and pulmonary hypertension. His diagnosis was delayed due to the lack of recognition of this clinical/radiographic entity. Fibrosing mediastinitis is a rare entity usually caused by granulomatous disease. Most cases develop as a late complication of histoplasmosis or TB. The presence of calcified mediastinal soft tissue infiltrates on advanced chest imaging can be diagnostic of fibrosing mediastinitis in patients with a prior history of a granulomatous infection once active processes such as malignancy are excluded.

Infective endocarditis (IE) is a unique diagnostic and therapeutic challenge. It is a severe disease, fatal before penicillin discovery. Atypical presentations frequently led to delayed diagnosis and poor outcome. There was little information about the natural history of the vegetations during medical treatment or the relation of morphologic changes in vegetation to late complications. Application of a new diagnostic criteria and echocardiography, increased the number of definite diagnosis. Trans-thoracic and trans-esophageal echocardiography had an established role in the management of patients with IE. The evolution of vegetation size, its mobility, and consistency, the extent of the disease, and the severity of valvular regurgutation were related to late complications. With therapeutic options including modern antibiotic treatment and early surgical intervention IE turned out to be a curable disease. Reduction in mortality also depended on prevention. Antibiotic prophylaxis of IE was important, but low mortality was also the result of early treatment, especially in the event of early recognition of symptoms and signs of the disease.

Whitley, Richard J

2009-07-01

Herpes zoster is a common late complication of varicella-zoster virus exposure and can be further complicated by postherpetic neuralgia. Ms A is a 70-year-old woman with shingles and Ramsay-Hunt syndrome who presented to the emergency department with a few days of earache followed by pain in the back of her head. Using her case as a springboard, the diagnosis, natural history, and treatment of herpes zoster and postherpetic neuralgia in immunocompetent older adults are reviewed, in addition to the effectiveness of the herpes zoster vaccine.

Minimally invasive surgical technique for tethered surgical drains

PubMed Central

Hess, Shane R; Satpathy, Jibanananda; Waligora, Andrew C; Ugwu-Oju, Obinna

2017-01-01

A feared complication of temporary surgical drain placement is from the technical error of accidentally suturing the surgical drain into the wound. Postoperative discovery of a tethered drain can frequently necessitate return to the operating room if it cannot be successfully removed with nonoperative techniques. Formal wound exploration increases anesthesia and infection risk as well as cost and is best avoided if possible. We present a minimally invasive surgical technique that can avoid the morbidity associated with a full surgical wound exploration to remove a tethered drain when other nonoperative techniques fail.

The role of the family doctor in fundamental in the prevention of diabetic complications, because these complications will be minor if there is good glycemic control during life. Determine the frequency of late complications of diabetes mellitus (DM) among IMSS-insured population in Ciudad Obregón, Sonora, México. A retrospective analysis included 252 diabetic patients selected by a systematized and stratified randomized sampling including all patient files available in the Family Medicine Unit 1 in Ciudad Obregón, Sonora. The information was taken from the clinical charts got by family physicians and specialists. We used descriptive statistics and correlation of Pearson looking for the association between glicemia's level and enough time to produce complications. Arterial hypertension was found in 168 cases (67%), hypertriglyceridemia in 148 (59.4%), neuropathy in 106 (42.6%), hypercholesterolemia in 89 (35.7%), retinopathy in 69 (27.5%), nephropathy in 51 (20.5%), diabetic foot in 27 (10.8%), ischemic cardiopathy in 25 (10%), cerebral thrombosis in 11 (4.4%). The period between DM diagnosis and the appearance of complications was 3.2 to 13.1 years. The correlations were high and significant in every complication. The frequency of DM complications in this study was very high, with an increasing tendency of developing complications throughout the time.

What can happen after lung transplantation and the importance of the time since transplantation: radiological review of post-transplantation complications.

PubMed

Daimiel Naranjo, I; Alonso Charterina, S

2016-01-01

Lung transplantation is the best treatment option in the final stages of diseases such as cystic fibrosis, pulmonary hypertension, chronic obstructive pulmonary disease, or idiopathic pulmonary fibrosis. Better surgical techniques and advances in immunosuppressor treatments have increased survival in lung transplant recipients, making longer follow-up necessary because complications can occur at any time after transplantation. For practical purposes, complications can be classified as early (those that normally occur within two months after transplantation), late (those that normally occur more than two months after transplantation), or time-independent (those that can occur at any time after transplantation). Many complications have nonspecific clinical and radiological manifestations, so the time factor is key to narrow the differential diagnosis. Imaging can guide interventional procedures and can detect complications early. This article aims to describe and illustrate the complications that can occur after lung transplantation from the clinical and radiological viewpoints so that they can be detected as early as possible.

Inflammatory nasal polyps: an unusual late complication of Silastic sheet repair of orbital floor fracture.

PubMed

Andrews, A E; Hicklin, L

2006-02-01

Silastic implants are very widely used in surgical practice and are considered to be relatively inert. They do however present with complications, including infection, local foreign body inflammatory response,calcification, migration and failure of repair of the defect, which sometimes may necessitate explantation. Head and neck implants do present a special case, as complications can cause obstruction and disruption of function in small cavities. A pertinent history, clinical review and computed tomography scan are usually invaluable in obtaining a diagnosis. We present a rare case of migrated Silastic orbital sheet, presenting as a nasal polyp and causing maxillary antral pain and infection. A detailed search of the medical literature revealed no other such case.

Pleuroparenchymal fibroelastosis as a series of airway complications associated with chronic graft-versus-host disease following allogeneic bone marrow transplantation.

2014-01-01

We herein report the case of a 31-year-old woman who presented with bilateral upper lobe volume loss and pleural irregularities with hilar retraction. She had undergone allogeneic bone marrow transplantation (BMT) for the treatment of acute lymphoblastic leukemia nine years earlier. A surgical lung biopsy showed pleural thickening and subpleural alveolar collapse and fibrosis, consistent with a diagnosis of pleuroparenchymal fibroelastosis (PPFE). Antecedent sicca syndrome and the absence of other causes of fibroelastosis suggested that these abnormalities were associated with chronic graft-versus-host disease (cGVHD). PPFE as a late, noninfectious complication is rare; however, the present case suggests a new class of BMT-related pulmonary complications associated with cGVHD.

2013-01-01

There is controversy in the literature about the choice of expectant medical treatment versus surgical treatment of hiatal hernias, depending on the presence or absence of symptoms. This study presents the results obtained by our group, considering disease duration and postoperative results. A total of 121 patients were included and divided by age, disease duration, type of hiatal hernia and postoperative outcome. In 32% of the patients younger than 70 years, symptom duration was longer than 11 years and 68% of those aged more than 71 years had long-term symptoms (p<.05). Type iv hernias (complex) and those with diameters measuring more than 16 cm were observed in the group with longer symptom duration. Complications were more frequent in the older age group, in those with longer symptom duration and in those with type iv complex hernias. There was no postoperative mortality and only one patient (0.8%) with a type iii hernia and severe oesophagitis required reoperation. We recommend that patients with hiatal hernia undergo surgery at diagnosis to avoid complications and risks. Older patients should not be excluded from surgical indication but should undergo a complete multidisciplinary evaluation to avoid complications and postoperative mortality. Copyright © 2012 AEC.

2011-01-01

Objectives To evaluate morbidity, mortality, and associated risk factors in late preterm term infants (34 0/7-36 6/7 wk) requiring extra-corporeal membrane oxygenation (ECMO). Study design We reviewed a total of 21,218 neonatal ECMO runs in Extracorporeal Life Support Organization (ELSO) registry data from 1986 to 2006. Infants were divided into 3 groups: Late Preterm (34 0/7 to 36 6/7), Early Term (37 0/7 to 38 6/7), and Full Term (39 0/7 to 42 6/7). Results There were 14,528 neonatal ECMO runs which met inclusion criteria. Late preterm infants experienced the highest mortality on ECMO (late preterm 26.2%, early term 18%, full term 11.2%. p<0.001) and had longer ECMO runs; they also had higher rates of serious complications. GA was a highly significant predictor for mortality. Late preterm infants with a primary diagnosis of sepsis and PPHN had 3-fold higher risk of mortality on ECMO than those with meconium aspiration. Conclusion Late preterm infants treated with ECMO havehigher morbidity and mortality than term infants. This underscores the need for special consideration of this vulnerable population in the diagnosis and treatment of hypoxic respiratory failure. PMID:21459387

The birth, death and resurrection of avoidance: a reconceptualization of a troubled paradigm.

LeDoux, J E; Moscarello, J; Sears, R; Campese, V

2017-01-01

Research on avoidance conditioning began in the late 1930s as a way to use laboratory experiments to better understand uncontrollable fear and anxiety. Avoidance was initially conceived of as a two-factor learning process in which fear is first acquired through Pavlovian aversive conditioning (so-called fear conditioning), and then behaviors that reduce the fear aroused by the Pavlovian conditioned stimulus are reinforced through instrumental conditioning. Over the years, criticisms of both the avoidance paradigm and the two-factor fear theory arose. By the mid-1980s, avoidance had fallen out of favor as an experimental model relevant to fear and anxiety. However, recent progress in understanding the neural basis of Pavlovian conditioning has stimulated a new wave of research on avoidance. This new work has fostered new insights into contributions of not only Pavlovian and instrumental learning but also habit learning, to avoidance, and has suggested that the reinforcing event underlying the instrumental phase should be conceived in terms of cellular and molecular events in specific circuits rather than in terms of vague notions of fear reduction. In our approach, defensive reactions (freezing), actions (avoidance) and habits (habitual avoidance) are viewed as being controlled by unique circuits that operate nonconsciously in the control of behavior, and that are distinct from the circuits that give rise to conscious feelings of fear and anxiety. These refinements, we suggest, overcome older criticisms, justifying the value of the new wave of research on avoidance, and offering a fresh perspective on the clinical implications of this work.

Multidisciplinary management of ornithine transcarbamylase (OTC) deficiency in pregnancy: essential to prevent hyperammonemic complications

PubMed Central

Lamb, Stephanie; Aye, Christina Yi Ling; Murphy, Elaine; Mackillop, Lucy

2013-01-01

Ornithine transcarbamylase (OTC) deficiency is the most common inborn error in the metabolism of the urea cycle with an incidence of 1 in 14 000 live births. Pregnancy can trigger potentially fatal hyperammonemic crises. We report a successful pregnancy in a 29-year-old primiparous patient with a known diagnosis of OTC deficiency since infancy. Hyperammonemic complications were avoided due to careful multidisciplinary management which included a detailed antenatal, intrapartum and postnatal plan. Management principles include avoidance of triggers, a low-protein diet and medications which promote the removal of nitrogen by alternative pathways. Triggers include metabolic stress such as febrile illness, particularly gastroenteritis, fasting and any protein loading. In our case the patient, in addition to a restricted protein intake, was prescribed sodium benzoate 4 g four times a day, sodium phenylbutyrate 2 g four times a day and arginine 500 mg four times a day to aid excretion of ammonia and reduce flux through the urea cycle.

1995-01-01

Spontaneous splenic rupture as a complication of infectious mononucleosis was diagnosed in a 19-year-old woman. Sonographic and MRI investigations revealed subcapsular hematoma of the spleen without overt rupture. The patient was managed conservatively. Somatostatin treatment was initiated in order to reduce splanchnic blood flow. Further clinical course of the patient was favourable. Seven days after the diagnosis of splenic rupture the patient was discharged from hospital. Non-operative management should be considered in patients with subcapsular splenic rupture to avoid complications of splenectomy (e.g. post-splenectomy sepsis).

Kawasaki disease is an acute febrile vasculitis of infancy and early childhood. It is uncommon in early infancy, because a significant proportion of these children do not meet the classical diagnostic criteria at this age. Infants younger than 6 months with persistent fever and some of the criteria of Kawasaki disease should always raise suspicion for Kawasaki disease early to avoid delayed diagnosis with severe cardiac complications. We present a 35-day-old infant with incomplete Kawasaki disease complicated with myocardial infarction during chicken pox.

Complications associated with prone surgical positioning during elective spine surgery have the potential to cause serious patient morbidity. Although many of these complications remain uncommon, the range of possible morbidities is wide and includes multiple organ systems. Perioperative visual loss (POVL) is a well described, but uncommon complication that may occur due to ischemia to the optic nerve, retina, or cerebral cortex. Closed-angle glaucoma and amaurosis have been reported as additional etiologies for vision loss following spinal surgery. Peripheral nerve injuries, such as those caused by prolonged traction to the brachial plexus, are more commonly encountered postoperative events. Myocutaneous complications including pressure ulcers and compartment syndrome may also occur after prone positioning, albeit rarely. Other uncommon positioning complications such as tongue swelling resulting in airway compromise, femoral artery ischemia, and avascular necrosis of the femoral head have also been reported. Many of these are well-understood and largely avoidable through thoughtful attention to detail. Other complications, such as POVL, remain incompletely understood and thus more difficult to predict or prevent. Here, the current literature on the complications of prone positioning for spine surgery is reviewed to increase awareness of the spectrum of potential complications and to inform spine surgeons of strategies to minimize the risk of prone patient morbidity.

Validating a predictive model for late rectal bleeding following external beam treatment for prostate cancer would enable safer treatments or dose escalation. We tested the normal tissue complication probability (NTCP) model recommended in the recent QUANTEC review (quantitative analysis of normal tissue effects in the clinic). One hundred and sixty one prostate cancer patients were treated with 3D conformal radiotherapy for prostate cancer at the British Columbia Cancer Agency in a prospective protocol. The total prescription dose for all patients was 74 Gy, delivered in 2 Gy/fraction. 159 3D treatment planning datasets were available for analysis. Rectal dose volume histograms were extracted and fitted to a Lyman-Kutcher-Burman NTCP model. Late rectal bleeding (>grade 2) was observed in 12/159 patients (7.5%). Multivariate logistic regression with dose-volume parameters (V50, V60, V70, etc.) was non-significant. Among clinical variables, only age was significant on a Kaplan-Meier log-rank test (p=0.007, with an optimal cut point of 77 years). Best-fit Lyman-Kutcher-Burman model parameters (with 95% confidence intervals) were: n = 0.068 (0.01, +infinity); m =0.14 (0.0, 0.86); and TD50 = 81 (27, 136) Gy. The peak values fall within the 95% QUANTEC confidence intervals. On this dataset, both models had only modest ability to predict complications: the best-fit model had a Spearman's rank correlation coefficient of rs = 0.099 (p = 0.11) and area under the receiver operating characteristic curve (AUC) of 0.62; the QUANTEC model had rs=0.096 (p= 0.11) and a corresponding AUC of 0.61. Although the QUANTEC model consistently predicted higher NTCP values, it could not be rejected according to the χ(2) test (p = 0.44). Observed complications, and best-fit parameter estimates, were consistent with the QUANTEC-preferred NTCP model. However, predictive power was low, at least partly because the rectal dose distribution characteristics do not vary greatly within this patient cohort.

Transcatheter Amplatzer occlusion of patent ductus artertiosus (PDA) has emerged as a minimally invasive alternative to surgical closure. The goal of this study was to compare long-term clinical outcomes between two procedures, especially on chronic residual shunt, late or very late procedure-related complications, and regression of pulmonary hypertension and left ventricular dilation. A total 255 patients having isolated PDA with a minimal diameter of >or= 4 mm treated from January 2000 to July 2003 were included in this study and have been followed up until July 2008. The patients were assigned to either the device or surgical closure group according to the patients' and/or their parents' preference. Baseline physical exams, chest roentgenography, electrocardiography, and echocardiography were performed preprocedure and at each follow-up. Seventy-two patients accepted the transcatheter procedure (Group-TC) and 183 underwent surgical operation (Group-SO) for PDA closure, both groups were similar in their demographics and preoperative clinical characteristics. There were no cardiac deaths and late complications such as infectious endocarditis and Amplatzer duct occluder (ADO) dislodge in either group. More acute procedure-related complications were recorded in Group-SO (13.7%) compared with Group-TC (1.4%) (P = 0.004). The recovery time was (8.7 +/- 2.3) days for the Group-SO and (1.3 +/- 0.5) days for the Group-TC (P < 0.001). The survival freedom from persistent residual shunt, defined as residual shunt that can not resolve automatically, was 91.3% for Group-SO and 98.6% for Group-TC (P = 0.037 by Log-rank test). There was no significant difference in regression of pulmonary hypertension and left ventricular dilation; neither survival freedom from pulmonary hypertension nor abnormal left ventricular end-diastolic volume index were significantly different between the surgical group and the Amplatzer group. Our study confirmed the long-term safety and efficacy of transcatheter Amplatzer occlusion. In comparison to the time-proven surgical closure, transcatheter Amplatzer occlusion was less invasive and associated with fewer complications and residual shunt, and as effective in the regression of pulmonary hypertension and left ventricular dilation.

To compare the rates of intraoperative and postoperative complications of robotic surgery and laparoscopy in the surgical treatment of endometrial cancer. Unicentric retrospective study (Canadian Task Force classification II-2). Tertiary teaching hospital. The study was performed from January 2002 to December 2011 and included patients with endometrial cancer who underwent laparoscopic or robotically assisted laparoscopic surgical treatment. Data collected included preoperative data, tumor characteristics, intraoperative data (route of surgery, surgical procedures, and complications), and postoperative data (early and late complications according to the Clavien-Dindo classification, and length of hospital stay). Morbidity was compared between the 2 groups. The study included 146 patients, of whom 106 underwent laparoscopy and 40 underwent robotically assisted surgery. The 2 groups were comparable in terms of demographic and preoperative data. Intraoperative complications occurred in 9.4% of patients who underwent laparoscopy and in none who underwent robotically assisted surgery (p = .06). There was no difference between the 2 groups in terms of postoperative events. Robotically assisted surgery is not associated with a significant difference in intraoperative and postoperative complications, even when there were no intraoperative complications of robotically assisted surgery.
