    Subclinical rejection (SCR) has been variably associated with reduced graft survival, development and progression of interstitial fibrosis/tubular atrophy and chronic allograft nephropathy, but data are controversial concerning SCR treatment in terms of graft survival improvement. In this single-center retrospective study, we enrolled 174 adult kidney transplant recipients with a protocol biopsy performed at 30 days after transplantation to evaluate the incidence rate and risk factors for early SCR and its impact on 10-year graft survival. Five patients showed primary non function and were excluded. Among 159/169 (94.08 %) patients with stable graft function who underwent protocol biopsy, 17 (10.7 %) showed signs of SCR and were treated with low-dose intravenous (i.v.) steroids. Ten patients showed functional impairment, 8 (4.73 %) resulting as acute rejection. At multivariate analysis, donor age [odds ratio (OR) 1.04, 95 % confidence interval (CI) 1.01-1.09], and delayed graft function (DGF) (OR 1.08, 95 % CI 1.03-1.12) were significantly associated with SCR. The 10-year graft survival rate in the SCR group was similar to that in the normal-findings group (76.5 vs. 74.9 % respectively; p = 0.61). At multivariate Cox regression, acute [hazard ratio (HR) 5.22, 95 % CI 1.70-16.01], but not sub-clinical, rejection was independently associated with long-term graft failure. In conclusion, early protocol biopsy is a useful and safe tool to detect early SCR which seems not to affect the long-term survival. We suggest that this could be, probably, linked to early SCR treatment with low dose i.v. steroids.

    Full Text Available A single center experience of first 100 liver transplantations (LTs is summarized. Analysis of trends in cadaver donor population and waiting list status changes, and also of early and late postoperative complications are presented. 100 LTs were performed for 95 patients (pts, retransplantation – 4 pts; one patient received 3 liver transplants (female – 55 pts, male – 40 pts, mean age – 39.9 ± 12.1 years. Cumulative 1-year survival rate of pts by Kaplan–Meyer was 91%, 3-year – 83%. Biliary complications were revealed in 9% of pts during 2–9 months after LT. 77 pts have been regularly observed in outpatient clinic, mean age – 44 ± 9.2 years, male – 35, fema- le – 42, follow-up period – 1 months up to 13 years after LT. 3.9% remained invalid with limitation of ability to work, 61.8% have been working, 22.3% were capable to work, retirees were 10.5%. Development of preoperati- ve planning, adequate organ selection will allow to improve the results of LT. Study of hematopoietic stem cells role will expand tools of prognosis of posttransplant complications.

    Purpose Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have been proposed for controlling peritoneal seeding metastasis in some kinds of cancers, including those of colorectal origin, but their safety and oncological benefits are subjects of debate. We present our early experience with those procedures. Methods Data were retrospectively collected from all patients with peritoneal carcinomatosis (PC) and pseudomyxoma peritonei (PMP) treated using CRS and HIPEC at Yonsei Cancer Center between July 2014 and July 2015. Short-term outcomes and risk factors for postoperative complications were analyzed. Results Twenty-three patients with PC (n = 18) and PMP (n = 5) underwent CRS and HIPEC. Median follow-up and age were 2 months and 54 years, respectively. The median peritoneal carcinomatosis index score was 15, and CC0-1 was achieved in 78.3% of all patients. The median operation time and bleeding loss were 590 minutes and 570 mL, respectively. Grade-IIIa/grade-IIIb complications occurred in 4.3% (n = 1)/26.1% (n = 6) of the patients within 30 days postoperatively, and no 30-day mortalities were reported. Factors related to postoperative complications with CRS and HIPEC were number of organ resection (P = 0.013), longer operation time (P patients treated with cetuximab for recurred colorectal cancer had grade-III postoperative complication. Conclusion Our initial experience with CRS and HIPEC presented about 30% grade-III postoperative complications. Therefore, expert surgeons need to perform those procedures with great caution in selected patients who might benefit from it.

    Full Text Available Introduction: End-stage renal disease in children is associated with numerous comorbidities and with age-specific mortality rates approximately 30 times higher than in healthy children. The first kidney transplantation in children was performed successfully in 1954. Surgical advances and new immunosuppressive medications have greatly improved patient’s and graft’s survival in the last years. Aim: Report Centro Hospitalar do Porto experience in pediatric renal transplantation in the last 30 years. Methods: Epidemiological and clinical data of all patients younger than 18 years, transplanted between January 1984 and August 2013, were collected from our database. In order to analyze the transplantation outcome in our center we compare graft survival between decades (1984-89 / 1990-99 / 2000-09 / 2010-13. We also compare graft survival between two age groups of patients (0-10 years ; 11-17 years at the time of surgery. Results: One hundred thirty-nine patients (58.3% male underwent 147 renal transplants (6.8% live donors. Congenital anomalies of the kidney and urinary tract (56.5% and glomerulonephritis (18.4% were the major causes of renal disease. Uncensored graft survivals rates at 5, 10, 15 and 20 years were 84.7%, 71.1%, 60.0% and 51.0%, while patient survivals were 97.9%, 95.9%, 94.7% and 94.7% respectively. Graft survival improved over time and the difference between the decades was statistically significant (p=0.004. Despite the better survival in the group of patients older than 11 years, graft’s survival difference between the two age groups was not statistically significant (p=0.697. Conclusion: The results of our hospital are comparable to other international centers. Significant improvement in survival was observed over the time. It seems that an accurate follow-up of our patients helps to minimize the negative impact of adolescence on graft survival rates.

    Over recent years the button vesicostomy has become an alternative management option in children with poor bladder emptying, when clean intermittent catheterisation (CIC) cannot be initiated for reasons of age, sensation, or urethral anatomy. This study reviews recent experience of this technique and evaluates its use. Retrospective review of patients who had a button vesicostomy to permit bladder drainage between 1998 and 2011. Thirty children underwent button vesicostomy insertion aged between 4 days and 16 years. Indications were neuropathic bladders (n = 15), congenital hypotonic bladders (n = 6), functional bladder disorders (n = 5), and post-obstruction bladders (n = 4). The median length of use was 11 months; however, 7 patients still have the button in situ. Minor complications (n = 12) included transient leakage, wound infection, and overgranulation. Major complications included 2 UTIs, 1 device failure, and 2 significant leaks, requiring revision of the tract and removal of the button. The button vesicostomy is a suitable and safe technique for use in the short- and medium-term. The procedure has minimal morbidity and therefore is acceptable to families. It has a wide scope, including patients with a neuropathic bladder as an alternative to CIC and where temporary drainage is required until bladder function can recover.

Pediatr Transplantation 2011: 15:240-244. © 2009 John Wiley & Sons A\\/S. Abstract:  We assessed our long-term experience with regards to the safety and efficacy of MMF in our pediatric renal transplant population and compared it retrospectively to our previous non-MMF immunosuppressive regimen. Forty-seven pediatric renal transplants received MMF as part of their immunosuppressive protocol in the period from January 1997 till October 2006 (MMF group). A previously reported non-MMF group of 59 pediatric renal transplants was included for comparative analysis (non-MMF group). The MMF group comprised 29 boys and 18 girls, whereas the non-MMF group comprised 34 boys and 25 girls. Mean age was 11.7 and 12 yr in the MMF and non-MMF groups, respectively. The incidence of acute rejection episodes was 11 (23.4%) and 14 (24%) in the MMF and non-MMF group, respectively. Two (3.3%) grafts were lost in the non-MMF group compared with one (2.1%) in the MMF group. Twenty-one (44.68%) patients in the MMF group developed post-transplant infections compared with 12 (20.33%) in the non-MMF group (p < 0.0001). In conclusion, the use of MMF in pediatric renal transplantation was not associated with a lower rejection rate or immunological graft loss. It did, however, result in a significantly higher rate of viral infections.

    Full Text Available BACKGROUND: Percutaneous pulmonary valvuloplasty is well established treatment of choice in pulmonary valve stenosis. AIM: The aim of our study was to present our experience with the interventional technique, its immediate and mid-term effectiveness as well as its complication rate. MATERIAL AND METHODS: The study included 43 patients, where 33 (74% of them were children between the age of 1 month and 15 years. RESULTS: The procedure was successful in 38 patients or 90%. Mean peak to peak transvalvular gradient was reduced from 91.2 mmHg (55-150 mmHg to 39.1 mmHg (20-80 mmHg. Follow- up of patients was between 2 and 13 years and included echocardiographic evaluation of pulmonary valve gradient, right heart dimensions and function as well as assessment of pulmonary regurgitation. We experienced one major complication pericardial effusion in a 5 months old child that required pericardiocenthesis. Six patients (13.9% required a second intervention. During the follow up period there was significant improvement of right heart function and echocardiography parameters. Mild pulmonary regurgitation was noted in 24 (55% patients, and four (9% patients developed moderate regurgitation, without affecting the function of the right ventricle. CONCLUSIONS: Percutaneous pulmonary valvuloplasty is an effective procedure in treatment of pulmonary stenosis with good short and mid-term results.

    We report our experience with the composition and management of caliceal diverticular stones for the past 13 years at our institution. Fourty patients with caliceal diverticular stones were treated percutaneously at Long Island Jewish Medical Center. The size of the diverticula ranged from 1 to 4.8 cm, with a mean size of 2.27 cm. The stone size ranged from 0.2 to 4.5 cm in diameter with an average of 1.7 cm. Twenty patients underwent a metabolic evaluation. Follow-up ranged from 8 months to 140 months with a mean of 72.5 months. We achieved a stone free rate of 95%. All 40 patients were free of pain and infection. The chemical composition of stones was identified in 38 patients. Twelve patients were found to have mainly calcium phosphate stones, 16 mainly calcium oxalate stones, 7 mainly uric acid stones and 3 were found with milk of calcium in their diverticulum. Thirty-five patients had complete resolution of their diverticula with normal urograms. The remaining 5 patients had at least 50% diminution of the diverticulum size. No one of the latter patients was found to have stone recurrence. Metabolic evaluation of the 40 patients showed in the 75% of the cases any metabolic abnormality, an absorptive hypercalciuria type II in two patients (10%), hyperuricosuric hypercalciuria in two cases (10%) and hyperoxaluria in one (5%). Percutaneous management of caliceal diverticular stones is a safe and effective modality compared to the existing alternative procedures reported in the literature.

    To evaluate the success and complication rates of a single center's multidisciplinary approach to transvenous lead extraction. One university hospital. One hundred ninety-five patients scheduled for transvenous lead extraction. A multidisciplinary approach to transvenous lead extraction involving cardiac surgery, electrophysiology, perfusion, and cardiac anesthesiology. A case series of 351 lead extractions performed in 195 patients over a 42-month period. Indications, success rates, and complication rates were tracked and retrospectively evaluated and reported. Indications for lead extraction included 53.3% because of lead malfunction, 36.9% because of infection, with the remaining 9.7% from other categories such as venous stenosis. The lead extraction rate was 99.7%, with complete removal in 97.7%. The overall major complication rate was 3.08%. After an initial 1-year period of performing lead extractions, the overall major complication rate reduced to 1.23%. Transvenous lead extraction generally is a safe procedure, but not without complications. A multidisciplinary approach involving cardiac surgery, electrophysiology, and cardiac anesthesiology allows for successful management and the ability to rapidly manage major complications.

  10. SINGLE-CENTER EXPERIENCE OF ABO-INCOMPATIBLE LIVER TRANSPLANTATION

    Directory of Open Access Journals (Sweden)

    S. V. Gautier

    2011-01-01

    Full Text Available Since 2008 up to 2010 eight ABO-incompatible liver transplantations have been performed in our center: one of them was urgent liver transplantation to adult patient from deceased donor, other seven were transplantations of left lateral segment to children from living relative donors. Own experience, as well as world one, proves, that barrier of ABO-incompatibility can be overcome more successfully in liver transplantation, particularly in pediatric population, that in other solid organs transplantation. Good results can be achieved even with less ag- gressive immunosuppressive therapy. Recipient conditioning before operation can significantly improve results of ABO-incompatible liver transplantation, but as own experience has shown, often there’s no need to hold some special preparation of children, because their anti-ABO antibodies are very low or absent before transplantation and do not increase after it. Thereby ABO-incompatible liver transplantation is reasonable in urgent cases and in pediatric population because of the limited pull of living relative donors for children.

    Full Text Available Introduction: Ambiguous genitalia are a major cause of parental anxiety and create psychological and social problems to patient, if not managed properly. Here we present our experience in managing patients with ambiguous genitalia. Material and Methods: We retrospectively reviewed clinical records of all patients with ambiguous genitalia managed surgically at out institute between December 1989 and January 2011. Relevant history, clinical examination , investigations and surgical procedures performed were analyzed and results were evaluated in terms of anatomical, functional and psychosexual outcomes. Results: Female pseudohermaphroditism was the most common cause of genital ambiguity in our patients. Male and female genitoplasty was done according to gender of rearing, genital anatomy and parental choice. Twenty six patients (86.6% reported satisfactory cosmetic outcome and 22 (73.3% satisfactory functional outcome on long term follow-up. Among the 24 patients diagnosed as male pseudohermaphroditism 14 (82.3% patient have reported satisfactory cosmetic outcome and 13 (76.4% have reported satisfactory functional outcome. In patients with mixed gonadal dysgenesis and true hermaphroditism satisfactory cosmetic and functional outcome was seen in 70% patient. Conclusion: Managing patients of genital ambiguity according to gender of rearing, genital anatomy and parental choice carries good prognosis in terms of anatomical, functional and psychosexual outcome.

    Capsule endoscopy (CE) is a novel technology that facilitates highly effective and noninvasive imaging of the small bowel. Although its efficacy in the evaluation of obscure gastrointestinal bleeding (OGIB) has been proven in several trials, data on uses of CE in different small bowel diseases are rapidly accumulating in the literature, and it has been found to be superior to alternative diagnostic tools in a range of such diseases.Based on literature evidence, CE is recommended as a first-line investigation for OGIB after negative bidirectional endoscopy. CE has gained an important role in the diagnosis and follow-up of Crohn's disease and celiac disease and in the surveillance of small bowel tumors and polyps in selected patients. Capsule retention is the major complication, with a frequency of 1%-2%. The purpose of this review was to discuss the procedure, indications, contraindications and adverse effects associated with CE. We also review and share our five-year experience with CE in various small bowel diseases. The recently developed balloon-assisted enteroscopies have both diagnostic and therapeutic capability. At the present time, CE and balloon-assisted enteroscopies are complementary techniques in the diagnosis and management of small bowel diseases.

    Purpose: Penile lichen sclerosus (LS) is a nagging condition and its progression result in devastating urinary and sexual problems and reduction in the quality-of-life. This study has been carried out to present our experience about this disease with simultaneous review of the available literature. Materials and Methods: This retrospective study has been done at a tertiary care center of eastern India. The data of 306 patients affected with LS were analyzed for clinical presentation, physical examination, investigations, and treatment offered. Results: Presenting symptoms were non-specific. The prepuce was most commonly involved location followed by glans and meatus. Urethral involvement was not isolated as the primary site. Circumcision was done in 237 patients, while 63 patients underwent meatotomy. Thirty-six of 39 cases of LS induced stricture were treated with buccal mucosal graft (BMG) either in one stage or in two stages. Conclusion: LS varies from being a highly aggressive disease of the penis and anterior urethra to a burnt out condition affecting just the meatus and surrounding glans. Early diagnosis and treatment are required to prevent its complication and associated morbidity. Management depends on the anatomical location of lesion, extent of involvement, rapidity of progression and its severity. Use of BMG in LS induced urethral stricture has shown encouraging results.

    BACKGROUND: Percutaneous transcatheter closure (PTC) of patent foramen ovale (PFO) is implicated in cryptogenic stroke, transitional ischemic attack (TIA) and treatment of a migraine. AIM: Our goal was to present our experience in the interventional treatment of PFO, as well as to evaluate the short and mid-term results in patients with closed PFO. MATERIAL AND METHODS: Transcatheter closure of PFO was performed in 52 patients (67.3% women, mean age 40.7 ± 11.7 years). Patients were interviewed for subjective grading of the intensity of headaches before and after the PFO closure. RESULTS: During 2 years of follow-up, there was no incidence of new stroke, TIA and/or syncope. Follow-up TCD performed in 35 patients showed complete PFO closure in 20 patients (57.1%). Out of 35 patients, 22 (62.9%) reported having a migraine before the procedure with an intensity of headaches at 8.1 ± 1.9 on a scale from 1 to 10. During 2 years of follow-up, symptoms of a migraine disappeared in 4 (18.2%) and the remaining 18 patients reported the significant decrease in intensity 4.8 ± 2.04 (p = 0.0001). In addition, following PFO closure the incidence of the headaches decreased significantly (p = 0.0001). CONCLUSIONS: Percutaneous transcatheter closure of PFO is a safe and effective procedure showing mid-term relief of neurological symptoms in patients as well as significant reduction of migraine symptoms.

    Full Text Available Renal transplantation (RTx is considered as the best therapeutic modality for patient suffering from end-stage renal disease (ESRD. Dearth of donor kidneys is a major problem everywhere, and deceased donor renal transplantation (DDRTx is seen as at least a partial solution. Even so, DDRTx accounts for only less than 4% of RTx in India. We report our 6-year single-center experience on DDRTx vis-à-vis patient/graft survival, graft function in terms of serum creatinine (SCr, rejection episodes, and delayed graft function (DGF. Between January 2005 and March 2011, 236 DDRTx were performed. Majority of the donors were those with brain death due to road traffic/cerebrovascular accidents. The commonest recipient diseases leading to ESRD were chronic glomerulonephritis (42.8%, diabetes (12.7%, and hypertension (10.6%. Mean recipient age was 36.2 ± 14.2 years; 162 were males and 74 were females. Mean donor age was 45.3 ± 17.13 years; 144 were males and 92 were females. Mean dialysis duration pre-transplantation was 18.5 ± 2.5 months. All recipients received single-dose rabbit-anti-thymocyte globulin induction and steroids, calcinueurin inhibitor, and mycophenolate mofetil/azathioprine for maintenance immunosuppression. Delayed graft function was observed in 29.6% patients and 22% had biopsy-proven acute rejection. Over the mean follow-up of 2.18 ± 1.75 years, patient and graft survival rates were 74.57% and 86.8%, respectively, with mean SCr of 1.42 ± 0.66 mg%. DDRTx achieves acceptable graft function with patient/graft survival, encouraging the use of this approach in view of organ shortage.

    To investigate the treatment outcomes of parotid gland cancer at a single center over a 10-year period and to evaluate the prognostic significance of maximum standardized uptake value. Retrospective case series with chart review. Academic care center. Ninety-eight patients with primary parotid gland cancer who were surgically treated at Yonsei University Head & Neck Cancer Clinic between January 1999 and December 2008 were analyzed. Patient data were collected retrospectively from medical charts. The investigators analyzed the association of clinicopathological factors and maximum standardized uptake value on (18)F-fluorodeoxyglucose positron emission tomography-computed tomography scan with disease-specific survival. Mean patient age was 49.7 years. Mean follow-up was 48.8 months. Thirty-three, 40, 30, and 23 patients had stage I, II, III, and IVA disease, respectively. Mucoepidermoid carcinoma was the most common histologic type (34.7%), followed by acinic cell carcinoma (27.6%). Eighteen patients (18.4%) experienced recurrences (mean recurrence gap, 20.6 months; range, 2-87 months). Five- and 10-year disease-specific survival rates were 93.6% and 81.8%, respectively. In the univariate analysis, pathologic T stage, pathologic lymph node status, resection margin, external parenchymal extension, and maximum standardized uptake value were significantly associated with disease-specific survival. Pathologic lymph node status and maximum standardized uptake value were independent prognostic factors in the multivariate analysis. Our single-center experience with parotid gland cancer treatment is consistent with the literature. Cervical lymph node metastasis and high maximum standardized uptake value are associated with poor survival in parotid gland cancer. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

    To analyze a single center experience of endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms. Results of 122 patients who underwent EVAR were analyzed, retrospectively. Sex, age, aneurysmal morphology, hostile neck anatomy, preprocedural and postprocedural sac-diameter, technical and clinical success, postprocedural complication and need of additional procedure were analyzed. A total of 111 male and 11 female patients were included. Morphology of the aneurysms was as follows: fusiform (n = 108), saccular (n = 3) and ruptured type (n = 11). Sixty-four patients had hostile neck anatomy. The preprocedural mean sac-diameter was 52.4 mm. Postprocedural sac-diameter was decreased or stable in 110 patients (90.2%) and increased in 8 patients (6.6%). Technical success rate was 100% and clinical success rate was 86.1%. Fifty-one patients showed endoleak (41.8%) and 15 patients (12.3%) underwent secondary intervention due to type I endoleak (n = 4), type II endoleak (n = 4) and stent-graft thrombosis (n = 7). EVAR is a safe and effective therapy for abdominal aortic aneurysm, and it has high technical success and clinical success rate, and low complication rate.

    Background Carotid artery stenting (CAS) as a competing treatment modality has had to adhere to limits to gain widespread acceptance in some studies.This study analyzed the clinical data of 1700 consecutive patients after CAS to retrospectively evaluate the 30-day outcome of CAS for internal carotid artery stenosis in a Chinese population.Methods Medical records of 1700 patients who underwent CAS at Xuanwu Hospital affiliated to Capital Medical University between January 2001 and August 2012 were reviewed.Postoperative 30-day complication rates were analyzed and compared with those of other studies.Univariate and multivariate Logistic regression analyses were used to identify factors associated with perioperation myocardial infarction (MI),stroke,and death.Results The overall 30-day rate of MI,stroke,and death after CAS was 2.53%.In univariate analysis,patients who were symptomatic,had a neurological deficit (modified Rankin score (mRS) ≥3; P=0.001),and who were not taking statins experienced a significantly increased rate of MI,stroke,and death (P=-0.017).In multivariate Logistic regression analysis,the presence of symptoms (odds ratio (OR)=2.485; 95% confidence interval (CI)=1.267-4.876; P=0.008) and a neurological deficit (mRS ≥3) (OR=3.025; 95% CI=1.353-6.763; P=0.007) were independent risk factors for perioperative MI,stroke,and death.Conclusions According to this single-center experience,CAS may effectively prevent and treat carotid artery stenosis that would otherwise lead to stroke.Being symptomatic and having a neurological deficit (mRS ≥3) increased the risk of perioperative MI,stroke,and death.

    Posttransplantation lymphoproliferative disorder (PTLD) is a serious complication following solid organ transplantation that has been linked to Epstein-Barr virus (EBV) infection. The aim of this article was to describe a single-center experience with the multiplicity of clinical presentations of PTLD. Among 350 liver transplantations performed in 303 children, 13 survivor children displayed a histological diagnosis of PTLD (13/242 survivors; 5.4%). The age at diagnosis ranged from 12 to 258 months (median, 47), and the time from transplantation ranged from 1 to 84 months (median, 13). Ten of these children (76.9%) were EBV-naïve prior to transplantation. Fever was present in all cases. The clinical signs at presentation were anemia (92.3%), diarrhea and vomiting (69.2%), recurrent upper airway infections (38.4%), Waldeyer ring lymphoid tissue hypertrophy (23.0%), abdominal mass lesions (30.7%), massive cervical and mediastinal adenopathy (15.3%), or gastrointestinal and respiratory symptoms (30.7%). One child developed fulminant hepatic allograft failure secondary to graft involvement by PTLD. Polymorphic PTLD was diagnosed in 6 patients; 7 had the diagnosis of lymphoma. Treatment consisted of stopping immunosuppression as well as starting intravenous gancyclovir and anti-CD20 monoclonal antibody therapy. The mortality rate was 53.8%. The clinical presentation of PTLD varied from fever of unknown origin to fulminant hepatic failure. The other symptoms that may be linked to the diagnosis of PTLD are pancytopenia, tonsil and adenoid hypertrophy, cervical or mediastinal lymph node enlargement, as well as abdominal masses. Despite numerous advances, the optimal treatment approach for PTLD is not completely known and the mortality rate is still high.

    Full Text Available Purpose: To present a single-center experience with 25 cases of bronchopulmonary malformations and the review the literature. Materials and Methods: We conducted a retrospective analysis of the medical records of patients with congenital bronchopulmonary malformations who were operated between July 1997 and July 2007 in our institute; we examined the modes of presentations, management, and outcome. Outcome of all patients was assessed over a short follow-up period (average 1.8 months. Results: Out of 25 patients, 18 (72% were male and 7 (28% were female. Age of patients ranged from 1 day to 11 years. The histopathological diagnosis was congenital cystic adenomatoid malformations [CCAM; n = 14 (56%], congenital lobar emphysema [CLE; n = 5 (20%], pulmonary sequestrations [PS; n = 3 (12%], and bronchogenic cysts [BC; n = 3 (12%]. Antenatal diagnosis was available in only 2 (8% patients. The common presenting symptoms were respiratory distress and chest infections. Lobectomy was the procedure of choice . Mortality was 16% (n = 4; M: F = 3: 1. Two patients died because of overwhelming sepsis, one from compromised cardiac function, and one from aspiration which might possibly have been prevented. Conclusion: Patients with progressive respiratory distress due to these anomalies may require urgent surgical intervention regardless of age. The surgical outcome is favorable, with manageable complications. Plain x-ray chest and CT of thorax are usually sufficient for diagnosis and planning of treatment. Pathological diagnosis may differ from the imaging diagnosis. Mortality is found to be more in neonates. Apart from initial stabilization, resection of lesion and careful postoperative care is necessary to reduce mortality and morbidity.

    Full Text Available The aim of this study is to report the experience from a single center in Libya, on the prevailing live-related kidney transplantation program. The results of three years work on kidney transplantation at the Tripoli Central Hospital (National Organ Transplant Program in Libya were evaluated. The transplant program was launched on 17 th August, 2004 and 135 patients have been transplanted since then till 17 th August, 2007. All donors and recipients were screened thoroughly prior to transplant and monitored closely in the post-transplant period. Our immuno-suppressive protocol was cyclosporine-based. Among the 135 accepted pairs, donors and reci-pients were genetically-related in 133 cases (98.5% and emotionally-related in two others. The mean donor age was 37 ± 9.5 years (range 18-56 years and recipient age 37 ± 13.6 years (range 7-67 years. There were 95 males (70.4% and 40 females (29.6% among the recipients while among the donors, there were 102 males (75.6% and 33 females (24.4%. Delayed graft function was seen in three patients (2.2%, acute rejection in six (4.4%, post-transplant urinary tract infection in six (4.4%, pneumonia in three (2.2%, ureteric kink in two (1.5% and urine leak in four (3.0%. Graft survival at 36 months was 93.3% while patient survival at the same period was 96.3%. This report indicates that the results of our transplant program are good and comparable with other international programs.

    Purpose Pancreaticoduodenectomy (PD) is a complex surgery associated with high morbidity, mortality, and cost. Municipal hospitals have their important role in the public health and welfare system. The purpose of this study was to identify the feasibility as well as the cost-effectiveness of performing PD in a mid-volume municipal hospital based on 13 years of experience with PD. Methods From March 2003 to November 2015, 183 patients underwent PD at Seoul Metropolitan Government - Seoul National University Boramae Medical Center.. Retrospectively collected data were analyzed, with a particular focus on complications. Hospital costs were analyzed and compared with a national database, with patients divided into 2 groups on the basis of medical insurance status. Results The percentage of medical aid was significantly higher than the average in Korean hospitals. (19.1% vs. 5.8%, P = 0.002). Complications occurred in 88 patients (44.3%). Postoperative pancreatic fistula (POPF) occurred in 113 cases (61.7%), but the clinically relevant POPF was 24.6% (grade B: 23.5% and grade C: 1.1%). The median hospital stay after surgery was 20 days (range, 6–137 days). In-hospital mortality was 3.8% (n = 7), with pulmonary complications being the leading cause. During the study period, improvements were observed in POPF rate, operation time, and hospital stay. The mean total hospital cost was 13,819 United States dollar (USD) per patient, and the mean reimbursement from the National Health Insurance Service (NHIS) to health care providers was 10,341 USD (74.8%). The patient copayment portion of the NHIS payment was 5%. Conclusion Performing PD in a mid-volume municipal hospital is feasible, with comparable results and cost-effectiveness. PMID:28203554

    To determine the efficacy of the Modified Atkins Diet (MAD) and Ketogenic Diet (KD) in seizure control within a population of myoclonic-astatic epilepsy (MAE) patients. This was a retrospective, single center study evaluating the seizure control by high fat diets. Seizure diaries kept by the parents performed seizure counts. All patients met the clinical criteria for MAE. Nine patients met the clinical criteria. We found that both the MAD and KD were efficacious in complete seizure control and allowed other medications to be stopped in seven patients. Two patients had greater than 90% seizure control without medications, one on the KD and the other on the MAD. Seizure freedom has ranged from 13 to 36 months, and during this time four patients have been fully weaned off of diet management. One patient was found to have a mutation in SLC2A1. Our results suggest that strictly defined MAE patients respond to the MAD with prolonged seizure control. Some patients may require the KD for seizure freedom, suggesting a common pathway of increased requirement for fats. Once controlled, those fully responsive to the Diet(s) could be weaned off traditional seizure medications and in many, subsequently off the MAD or KD. Copyright © 2014 British Epilepsy Association.

    We aimed to determine the prevalence of cholesterol gallstones, the compositional changes of gallstones and its predisposing factors in Korea with this single-center study. Data of 365 patients who underwent cholecystectomy for cholecystolithiasis from July 2008 to September 2011 were reviewed. Based on the compositional analysis of the gallstones, patients were assigned to either cholesterol gallstone group or pigment gallstone group. The characteristics of the patients and the gallstones were summarized and compared. After eight patients with mixed gallstones were excluded, 357 patients were enrolled in the study, including cholesterol gallstones in 175 (49.0%) and pigment gallstones in 182 (51.0%). The number of patients with cholecystolithiasis increased but the prevalence of cholesterol gallstone decreased with age. Compared with the pigment gallstone group, the cholesterol gallstone group was associated with young age (gallstones in Korea has been stationary so far, but may change in the future since cholesterol gallstones are increasingly prevalent in the young generation. © 2013 Wiley Publishing Asia Pty Ltd and Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine.

    Post-transplant lymphoproliferative disease (PTLD) is a rare and serious complication after allogeneic hematopoietic stem cell transplantation (allo-HSCT) or solid organ transplantation. We conducted a retrospective analysis of the occurrence of post-transplant lymphoproliferative disease in allo-HSCT recipients over 12 years in a single center in China. A total of 343 patients received allo-HSCT. The conditioning therapy consisted of a busulfan/cyclophosphamide-based regimen, a fludarabine/cyclophosphamide-based regimen, or total-body irradiation and cyclophosphamide. In transplantations from unrelated donors and haplo-identical donors, patients also received antithymocyte globulin (ATG) or thymoglobulin as part of the conditioning. Five of the 343 patients (1.46%) were diagnosed with PTLD and all 5 were given ATG as part of conditioning. Among these 5 patients, 4 had lymphoid neoplasm before transplantation. EBV-positivity was confirmed in 4 patients. All 5 PTLD patients received reduction of immunosuppression (RI) as fundamental therapy. At follow-up on April 1, 2013, 1 patient had survived for 2 years and 1 had survived for 9 years. The correlation of PTLD with ATG and underlying diseases were examined by statistical analysis using the chi-squared test or Fisher's exact test (P=0.011 and 0.025, respectively). Although only 1.46% of patients progressed to PTLD associated with ATG and underlying diseases, the mortality was still high. Moreover, RI can be an effective therapy for PTLD patients, but other approaches should be further explored.

    Refractory celiac disease (RCD) occurs when both symptoms and intestinal damage persist or recur despite strict adherence to a gluten-free diet. In RCD, the immunophenotype of intraepithelial lymphocytes may be normal and polyclonal (RCD I) or abnormal and monoclonal (RCD II). The aim is to describe the clinical characteristics, treatment, and long-term outcome in a large single-center cohort of patients with RCD. We compared the clinical characteristics and outcome in 57 patients with RCD: 42 with RCD I and 15 with RCD II. Fifteen of 57 patients died during follow-up (n=8 with RCD I and n=7 with RCD II), each within the first 2 years after RCD diagnosis. The overall 5-year cumulative survival is 70%, 80%, and 45% for the entire cohort, RCD I, and RCD II, respectively. The refractory state itself and enteropathy-associated T-cell lymphoma (EATL) were the most common causes of death, respectively. A new staging system is proposed based on the cumulative effect of 5 prognostic factors investigated at the time of the refractory state diagnosis: for patients in stages I, II, and III, the 5-year cumulative survival rate was 96%, 71%, and 19%, respectively (PRCD is associated with high mortality with RCD II having an especially poor prognosis because of the development of EATL. A new staging model is proposed that may improve the precision of prognosis in patients with RCD.

    Full Text Available It has been reported that kidney retransplant patients had high rates of early acute rejection due to previous sensitization. In addition to the acute antibody-mediated rejection (ABMR that has received widespread attention, the early acute T-cell-mediated rejection (TCMR may be another important issue in renal retransplantation. In the current single-center retrospective study, we included 33 retransplant patients and 90 first transplant patients with similar protocols of induction and maintenance therapy. Analysis focused particularly on the incidence and patterns of early acute rejection episodes, as well as one-year graft and patient survival. Excellent short-term clinical outcomes were obtained in both groups, with one-year graft and patient survival rates of 93.9%/100% in the retransplant group and 92.2%/95.6% in the first transplant group. Impressively, with our strict immunological selection and desensitization criteria, the retransplant patients had a very low incidence of early acute ABMR (6.1%, which was similar to that in the first transplant patients (4.4%. However, a much higher rate of early acute TCMR was observed in the retransplant group than in the first transplant group (30.3% versus 5.6%, P<0.001. Acute TCMR that develops early after retransplantation should be monitored in order to obtain better transplant outcomes.

    Full Text Available Background. We examined overall and disease-free survivals in a cohort of patients subjected to resection of liver metastasis from colorectal cancer (CRLM in a 10-year period when new treatment strategies were implemented. Methods. Data from 239 consecutive patients selected for liver resection of CRLM during the period from 2002 to 2011 at a single center were used to estimate overall and disease-free survival. The results were assessed against new treatment strategies and established risk factors. Results. The 5-year cumulative overall and disease-free survivals were 46 and 24%. The overall survival was the same after reresection, independently of the number of prior resections and irrespectively of the location of the recurrent disease. The time intervals between each recurrence were similar (11 ± 1 months. Patients with high tumor load given neoadjuvant chemotherapy had comparable survival to those with less extensive disease without neoadjuvant chemotherapy. Positive resection margin or resectable extrahepatic disease did not affect overall survival. Conclusion. Our data support that one still, and perhaps to an even greater extent, should seek an aggressive therapeutic strategy to achieve resectable status for recurrent hepatic and extrahepatic metastases. The data should be viewed in the context of recent advances in the understanding of cancer biology and the metastatic process.

    Full Text Available Background : 5-Flourouracil (FU-based chemotherapy (CT and concurrent 45 Gy radiotherapy (RT is one of the standard postoperative approaches currently used in gastric carcinoma. The high toxicity rates of this treatment leads to interruption of treatment in the majority of patients. In our study, we investigated the rates of toxicity and treatment discontinuation observed during postoperative FU-based chemoradiotherapy (CRT; retrospectively evaluated the effect of CRT and the other prognostic factors on local and distant control and survival. Patients and Methods: A total of 160 patients consisting of 97 total and 63 subtotal gastrectomy receiving postoperative CRT, have been studied retrospectively. Results : Patients who had to discontinue the treatment for a median of 6 (range, 3-13 days experienced toxicity during treatment at a rate of 43%. During the 21 (range, 4-68 months of follow-up local recurrences were observed in 8 (5% patients and distant recurrences were observed in 41 (25.6% patients. While the 1-3 year overall survival (OS rates were 75% and 42%, 13-year disease-free survival (DFS rates were 63% and 42%, respectively. In the univariate analysis for OS and DFS demonstrated statistical significance for below those 60 years of age, D1-D2 dissection type, negative surgical margin, early treatment beginning, the absence of invasion, and early stage disease. D1D2 dissection type, early treatment begining, age below 60 years and early stage disease significantly improve OS and DFS in multivarite analysis. Conclusions: Survival is worse in patients older than 60 years, had late treatment begining, advanced stage and D0 dissection.

    Full Text Available The aim of this study was to assess the clinical sensitivities of the tumor markers chromogranin A (CgA, urinary 5-hydroxyindoleacetic acid (5-HIAA and alkaline phosphatase (AP in neuroendocrine tumors (NETs of the GastroEnteroPancreatic-(GEP- system depending on tumor primary location and metastatic spread. In a retrospective single-center series, sensitivities were evaluated in serum samples from 110 patients with midgut (n = 62 and pancreatic (n = 48 NETs. CgA levels were analyzed by a commercially-available immunoradiometric assay (CIS-bio during routine follow-up in the years 2000–2009. CgA showed a higher sensitivity for midgut (68% than pancreatic (54% NETs. A higher CgA sensitivity and significantly higher median CgA values were found in patients with liver metastases than in those without, and in patients with hepatic and additionally extra-hepatic metastases than in those with hepatic and nodal metastases alone, respectively. We found an overall sensitivity for elevated 5HIAA excretion of 69% for midgut NETs and a significant correlation between median CgA and 5-HIAA values. The sensitivity of AP and the correlations of AP/CgA-data-pairs were low in both midgut and pancreatic NETs, although highest for metastatic pancreatic NETs. The sensitivity of CgA measurement depends on the NET primary location and spread of disease. 5-HIAA and CgA showed comparable sensitivity in midgut NETs, while AP does not seem to be useful as a tumor marker in GEP-NETs.

    Mycetoma is a chronic granulomatous disease. It is classified into eumycetoma caused by fungi and actinomycetoma due to filamentous actinomycetes. Mycetoma can be found in geographic areas in close proximity to the Tropic of Cancer. Mexico is one of the countries in which this disease is highly endemic. In this retrospective study we report epidemiologic, clinical and microbiologic data of mycetoma observed in the General Hospital of Mexico in a 33 year-period (1980 to 2013). A total of 482 cases were included which were clinical and microbiology confirmed. Four hundred and forty four cases (92.11%) were actinomycetomas and 38 cases (7.88%) were eumycetomas. Most patients were agricultural workers; there was a male predominance with a sex ratio of 3:1. The mean age was 34.5 years old (most ranged from 21 to 40 years). The main affected localization was lower and upper limbs (70.74% and 14.52% respectively). Most of the patients came from humid tropical areas (Morelos, Guerrero and Hidalgo were the regions commonly reported). The main clinical presentation was as tumor-like soft tissue swelling with draining sinuses (97.1%). Grains were observed in all the cases. The principal causative agents for actinomycetoma were: Nocardia brasiliensis (78.21%) and Actinomadura madurae (8.7%); meanwhile, for eumycetomas: Madurella mycetomatis and Scedosporium boydii (synonym: Pseudallescheria boydii) were identified. This is a single-center, with long-follow up, cross-sectional study that allows determining the prevalence and characteristics of mycetoma in different regions of Mexico.

    The effects of extracorporeal membrane oxygenation (ECMO) support on renal function in children with critical illness are unknown. The objective of this study was to investigate the impact of ECMO on renal function among children in different age groups. We performed a single-center retrospective observational study in critically ill children ≤ 18 years supported on ECMO for refractory cardiac or pulmonary failure (2006-2012). The patient population was divided into four age groups for the purpose of comparisons. The Acute Kidney Injury Network's (AKIN's) validated, three-tiered staging system for acute kidney injury was used to categorize the degree of worsening renal function. Data on patient demographics, baseline characteristics, renal function parameters, dialysis, ultrafiltration, duration of mechanical cardiac support, and mortality were collected. Comparisons of baseline characteristics, duration of mechanical cardiac support, and renal function were made between the four age groups. During the study period, 311 patients qualified for inclusion, of whom 289 patients (94%) received venoarterial (VA) ECMO, 12 (4%) received venovenous (VV) ECMO, and 8 (3%) received both VV and VA ECMO. A total of 109 patients (36%) received ultrafiltration on ECMO, 58 (19%) received hemodialysis, and 51 (16%) received peritoneal dialysis. There was a steady and sustained improvement in renal function in all age groups during the ECMO run, with the maximum and longest-sustained improvement occurring in the oldest age group. Proportions of patients in different AKIN stages remained similar in the first 7 days after ECMO initiation. We demonstrate that renal dysfunction improves early after ECMO support. Irrespective of the underlying disease process or patient age, renal function improves in children with pulmonary or cardiac failure who are placed on ECMO.

    Full Text Available Background and Aims. While several case reports on ischemic colitis (IC suggest the presence of predisposing causative factors, a few studies have investigated the predisposing factors in IC. This study aimed to identify the characteristics of patients with IC, particularly focusing on the predisposing factors. Methods. We conducted a single-center, retrospective analysis of 159 patients with IC. Clinical characteristics, laboratory data, endoscopic findings, and medical records were reviewed. Data were compared between groups of patients defined according to the predisposing factors. The predisposing factors are defined as temporary states or episodic events occurring within a week before the development of IC such as colonoscopy, enema, use of laxatives, heavy drinking, pancreatitis, shock, and burn. Results. Compared to the group of patients without predisposing factors of IC, the group of patients with predisposing factors was characterized by a relatively higher prevalence of male sex (56.9% versus 33.3%, p=0.005, younger age (60.9 ± 15.4 versus 67.2 ± 13.4 years, p=0.010, lower incidence of hypertension (43.1% versus 60.2%, p=0.044, and fewer risk factors (1.24 ± 1.18 versus 1.82 ± 1.22, p=0.005. Conclusions. Among men with predisposing factors, IC may develop even at a relatively younger age and in the absence of multiple risk factors, suggesting that predisposing factors may be involved in the pathogenesis of IC.

    To analyze the outcome of patients undergoing percutaneous CT-guided radiofrequency ablation (RFA) of small renal masses (SRM) at a single center during a ten-year time period. Patient records of renal RFAs (07/2003 - 11/2013) were reviewed. Indications were SRM suspicious of malignancy on imaging and one of the following: severe comorbidity; old age; solitary kidney; impaired renal function; patient wish. Biopsy was performed at the time of RFA. Patients were excluded if no follow-up was available. Patient and procedural characteristics were recorded. Survival rates were calculated using the Kaplan-Meier's method and compared with log-rank or cox tests. 38 patients (16 females, mean age 70.0 years [range 52 - 87]) presenting with a solitary SRM were included in the study. Biopsy showed malignancy in 29 patients; 9 had benign tumors. 26 patients suffered from cardiovascular, respiratory or hepatic comorbidities. Technical success (complete ablation on first follow-up) was achieved in 95 % of cases. Two major complications (bowel perforation; hematothorax) occurred. The 3- and 7-year overall survival (OS) [any cause] rates were 73.4 ± 0.8 % and 50.3 ± 1.0 %, respectively (mean follow-up 54.6 months, range 1 - 127). 4 recurrences and 2 metastases were observed. The presence of comorbidities was the only independent predictor of OS. There was no difference in survival between patients with benign and malignant tumors. RFA of SRM is successful in a large percentage of cases with a low complication rate and durable local control. As RFA is typically performed in multimorbid patients, overall survival seems to depend primarily on comorbidities rather than cancer progression.

    Background Immunoglobulin A nephropathy (IgAN) is the most common primary glomerulonephritis. Patients manifest variable clinical symptoms (eg, microhematuria) with preserved or progressive deterioration of renal function resulting in end-stage renal disease. The aim of this study was to evaluate patients from a single center to describe the clinical features, treatments, and follow-up results of those with the disease. Methods This is a retrospective data study of all children with IgAN. Patients who had a histopathologically proven diagnosis of IgAN and were followed up for at least 5 years were included in the study. Renal biopsy, graded as Hass classification, was performed on all patients. A total of 39 patients were included in the study. Results The mean follow-up time (± standard deviation) was 10.4 ± 3.51 (range 5–16) years. Twenty-nine patients (74.4%) were male and ten (25.6%) were female. Nineteen (48.7%) patients presented with recurrent macroscopic hematuria, ten (25.6%) with microscopic hematuria ± proteinuria, six (15.4%) with nephritic syndrome, and four (10.3%) with nephrotic syndrome. All patients underwent a renal biopsy, which was graded according to the Hass classification. At the end of follow-up time, 18 (46.1%) patients were normal, 15 (38.5%) had minor urinary abnormalities, three (7.7%) had active renal disease, and three (7.7%) developed renal failure. Conclusion The results of the present study are better than those from most other series. The majority of children with IgAN in this study were admitted with recurrent macroscopic hematuria and found to have a good prognosis. We suggest that children with IgAN have a good prognosis in the first 5-year follow-up period. PMID:22334797

    To identify possible predictors of pathologic complete response (pCR) of rectal cancer after preoperative concurrent chemoradiotherapy (CCRT). We conducted a retrospective review of 53 patients with rectal cancer who underwent preoperative CCRT followed by radical surgery at a single center between January 2007 and December 2012. The median radiotherapy dose to the pelvis was 54.0 Gy (range, 45.0 to 63.0 Gy). Five-fluorouracil-based chemotherapy was administered via continuous infusion with leucovorin. The pCR rate was 20.8%. The downstaging rate was 66%. In univariate analyses, poor and undifferentiated tumors (p = 0.020) and an interval of ≥7 weeks from finishing CCRT to surgery (p = 0.040) were significantly associated with pCR, while female gender (p = 0.070), initial carcinoembryonic antigen concentration of <5.0 ng/dL (p = 0.100), and clinical stage T2 (p = 0.100) were marginally significant factors. In multivariate analysis, an interval of ≥7 weeks from finishing CCRT to surgery (odds ratio, 0.139; 95% confidence interval, 0.022 to 0.877; p = 0.036) was significantly associated with pCR, while stage T2 (odds ratio, 5.363; 95% confidence interval, 0.963 to 29.877; p = 0.055) was a marginally significant risk factor. We suggest that the interval from finishing CCRT to surgery is a predictor of pCR after preoperative CCRT in patients with rectal cancer. Stage T2 cancer may also be an important predictive factor. We hope to perform a robust study by collecting data during treatment to obtain more advanced results.

    BACKGROUND: Acute pancreatitis is a relatively rare but po-tentially lethal complication after transarterial chemotherapy. This study aimed to review the complications such as acute pancreatitis after transarterial chemotherapy with or without embolization for hepatocellular carcinoma. METHODS: A total of 1632 patients with hepatocellular car-cinoma who had undergone transarterial chemoembolization from January 2000 to February 2014 in a single-center were reviewed retrospectively. We investigated the potential com-plications of transarterial chemoembolization, such as acute pancreatitis and acute pancreatitis-related complications. RESULTS: Of the 1632 patients with hepatocellular carcinoma who had undergone 5434 transarterial chemoembolizations, 1328 were male and 304 female. The median age of these pa-tients was 61 years. Most (79.6%) of the patients suffered from HBV-related hepatocellular carcinoma. The median tumor size was 5.2 cm. Of the 1632 patients, 145 patients underwent transarterial chemoembolization with doxorubicin elut-ing bead, making up a total of 538 episodes. The remaining patients underwent transarterial chemoembolization with cisplatin. Seven (0.4%) patients suffered from acute pancre-atitis post-chemoembolization. Six patients had chemoembo-lization with doxorubicin and one had chemoembolization with cisplatin. Patients who received doxorubicin eluting bead had a higher risk of acute pancreatitis [6/145 (4.1%) vs 1/1487 (0.1%), P CONCLUSIONS: Acute pancreatitis after transarterial chemo-embolization could result in serious complications, especially after treatment with doxorubicin eluting bead. Continuation of current treatment with transarterial chemoembolization after acute pancreatitis is feasible providing the initial attack is completely resolved.

    PurposeCarotid endarterectomy and stenting are used to treat carotid stenosis, with the volume of carotid artery procedures increasing over the past decade. We investigated the 10-year trend of periprocedural complications with an increasing procedure volume of carotid stenting at a single tertiary hospital.MethodsWe collected 416 consecutive cases (384 patients) of carotid artery stenting performed for either symptomatic (231 cases, 55.5 %) or asymptomatic (185 cases, 44.5 %) internal carotid artery stenosis at a single center. Periprocedural complication was defined as any stroke, myocardial infarction, or death. Procedure-related outcome included any dissection, hemodynamic event, or periprocedural complication.ResultsThe mean age was 68.8 years (82.8 % males; range of 20–89 years); 23.9 % were older than 75 years. Before the procedure, 99.3 and 56.0 % of patients received antiplatelet and lipid-lowering medication, respectively. The overall periprocedural complication rate was 3.6 % (1.6 and 5.2 % in the asymptomatic and symptomatic group, respectively). The composite outcome of any stroke or death was 3.4 %. Periprocedural complication and procedure-related outcome showed a decremental trend with increasing procedure volume, and this trend remained after adjusting for confounders.ConclusionsOur study suggests that carotid stenting at an experienced center might reduce the periprocedural complications. Our periprocedural complication rate of carotid artery stenting may be comparable to, or somewhat lower than, that reported in other clinical trials.

    To evaluate the impact of the presence of a congenital heart anomaly (CHA) and its potential contribution to morbidity and mortality in infants with congenital diaphragmatic hernia (CDH). In this retrospective cohort study, prenatal and postnatal data of all newborns diagnosed with CDH between January 2004 and December 2012 in a single center were reviewed. Cases were classified into two groups: those with 'isolated' CDH and those with both CDH and CHA. Patients with CHA were further subclassified into those with a major or minor CHA based on the Risk Adjustment for Congenital Heart Surgery-1 (RACHS-1), and the Society of Thoracic Surgeons-European Association for Cardiothoracic Surgery (STS-EACTS) scoring systems. Patients with associated non-cardiac anomalies, including 'syndromic cases', were excluded from the analysis. Primary and secondary outcomes were survival up to 1 year of age and a need for extracorporeal membrane oxygenation (ECMO), respectively. Of the 180 infants with CDH, 41 were excluded because of the presence of non-cardiac associated anomalies, 118 had isolated CDH and 21 had CDH with CHA (16 with minor and five with major CHA). Receiver-operating characteristics curve analysis demonstrated that the best cut-off for survival was when the score for CHA was ≤ 2 for both RACHS-1 (area under the curve (AUC), 0.74 (P = 0.04); sensitivity, 80.0%; specificity, 87.5%) and STS-EACTS (AUC, 0.83 (P = 0.03); sensitivity, 100%; specificity, 87.5%). Survival rate at 1 year was significantly lower in those with CHD and a major CHA (40.0%; P = 0.04) than in those with isolated CDH (77.1%) and those with CDH and a minor CHA (81.3%). We found no significant differences among the groups with regard to the need for ECMO. In general, a milder form of CHA does not appear to have a negative impact on the survival of infants with CDH. However, mortality appears to be significantly higher in infants with CDH and a major form of CHA. The scoring systems

    Full Text Available Background: Indian-Asian multiple sclerosis behaves somewhat differently from Western disease. It is not known if the response to β-interferon is also different. Aim: To demonstrate the decrease in relapses with β-interferon in Indian patients with multiple sclerosis. Patients and Methods: Patients with relapsing-remitting or secondary progressive multiple sclerosis with at least two relapses were started on β-interferon. Results: Sixteen patients were followed up for a period of 1-3 years. Fifteen had relapsing-remitting multiple sclerosis (MS. The mean number of relapses in these patients before interferons were started was 3.4. The mean yearly relapse rate was 1.3. The mean Kurtzke Expanded Disability Status Scale (EDSS at the start of β-interferon therapy in relapsing-remitting MS was 1.7. Ten of these patients were on Avonex® (interferon β1a and six (including the patient with secondary progressive MS were on Betaferon® (interferon β1b. On follow-up, three patients (two on Avonex® and one on Betaferon® had relapses. The respective β-interferon being received by these patients was continued, with no further relapses. The remaining patients had no relapse or clinical or MRI progression after starting the drug. The side effect profile of the drug in these patients was favorable; although nearly all developed fever on the first day of the injection, only 50% of the patients continued to have fever after 3 months. Two patients developed psychiatric symptoms, requiring discontinuation of the drug. Conclusion: Our prospective follow-up study shows that β-interferons are safe and effective in Indian patients with relapsing-remitting or secondary progressive MS.

    To prospectively evaluate the long-term clinical safety and efficacy of a newly designed self-expanding metallic stent (SEMS) in the treatment of patients with achalasia. Seventy-five patients with achalasia were treated with a temporary SEMS with a 30-mm diameter. The SEMSs were placed under fluoroscopic guidance and removed by gastroscopy 4-5 days after stent placement. Follow-up data focused on dysphagia score, technique and clinical success, clinical remissions and failures, and complications and was performed at 6 months, 1 year, and within 3 to 5 years, 5 to 8 years, 8 to 10 years, and >10 years postoperatively. Stent placement was technically successful in all patients. Complications included stent migration (n=4, 5.33%), chest pain (n=28, 38.7%), reflux (n=15, 20%), and bleeding (n=9, 12%). No perforation or 30-day mortality occurred. Clinical success was achieved in all patients 1 month after stent removal. The overall remission rates at 6 months, 1, 1-3, 3-5, 5-8, 8-10, and >10 year follow-up periods were 100%, 96%, 93.9%, 90.9%, 100%, 100%, and 83.3%, respectively. Stent treatment failed in six patients, and the overall remission rate in our series was 92%. The median and mean primary patencies were 2.8 {+-} 0.28 years (95% CI: 2.25-3.35) and 4.28 {+-} 0.40 years (95% CI: 3.51-5.05), respectively. The use of temporary SEMSs with 30-mm diameter proved to be a safe and effective approach for managing achalasia with a long-term satisfactory clinical remission rate. (orig.)

    To review cases of placenta previa in the last 13 years in a tertiary teaching hospital to identify risk factors for maternal morbidity.  A retrospective analysis of all cases of placenta previa managed at King Abdulaziz University Hospital (KAUH), Jeddah, Kingdom of Saudi Arabia from January 2001 to December 2013.    The total number of deliveries was 55,862 deliveries, and 11,412 (20.3%) delivered by cesarean section (C/S). The charts of 230 cases diagnosed with placenta previa was reviewed, and different variables were collected and analyzed. Diagnoses were achieved in 94% of them using ultrasound. The prevalence rate of placenta previa was 4.1 per 1000 births. Cesarean section was carried out as an emergency procedure in 130 (56.5%) women and as elective in 100 (43.5%) women. Of them, 26 patients were admitted to the intensive care unit (ICU) (11.3%), all of which received blood transfusion >6 units and 22 patients had a hysterectomy for uncontrollable bleeding.   Placenta previa is one of the leading causes of maternal morbidity and mortality. Every hospital must have a protocol, or algorithm for the management of placenta previa. Risk factors for maternal morbidity included complete previa, history of previous C/S, emergency C/S at a gestational age of less than 36 weeks, and estimated blood loss more than 2000 ml.

    Tuberculosis had been declared by the World Health Organization (WHO) as 'public health emergency' in 1993. Extra pulmonary tuberculosis (E.P.T.B.) comprises 20-25% total burden of the disease in which genitourinary tuberculosis (GU.T.B.) is 4%. Timely diagnosis and treatment will prevent the sequelae of this disease. To know the varied clinical presentations, diagnostic modalities and management of G.U.T.B. During a 13-year-period, 117 retrospective cases of GUTB were admitted in the tertiary care centre. They were analyzed for clinical presentation, diagnostic modalities and management. Young patients mainly in third decade of life were commonly affected with higher incidence in females. In our study, the most common presentation was irritative voiding symptoms (66.47%) followed by haematuria (47.60%). Although it can affect the entire organ in genito-urinary system but, in the present study, kidney was the most affected organ (64.9%) following ureter (27.35%), urinary bladder (17.09%), prostate (3.4%) and epididymis (5.19%). In this study, we had not encountered any case of testicular and penile tuberculosis. Among the different diagnostic modalities in this study, the diagnostic positivity rate was 41.6% for the urine AFB test, 55.4% for the urine M. tuberculosis culture test and 67.7% for PCR. Chest x-ray was positive in 25.6% (30). ESR was raised in 62.5% and Mantoux test was positive in 61.2% patients. A high index of suspicion and a wide range of investigations may be required to achieve a complete diagnosis of genitourinary tuberculosis. Though short course chemotherapy with four-drug-regimen for six-month-duration is the mainstay of treatment, surgical interventions were required in 60% of cases of this study.

    Full Text Available Objectives: A thyroglossal duct cyst (TDC is a frequent congenital midline anomaly of the neck that usually manifests during the first decade of life. We aimed to describe the presentation, management, and outcome of TDC in pediatric and adult cases. Methods: A retrospective observational analysis was conducted for all patients diagnosed and treated for TDC between 2000 and 2014 in a single center in Qatar. Data included patients’ demographics, presentations, preoperative investigations, anesthesia type, histopathological findings, surgical management, recurrences, and complications. Results: We identified 102 patients, of which 57% were males. The mean age of patients was 20.2±15.6 years. A bimodal distribution of TDC has been observed, which peaked between the ages of 6–13 years and at ≥19 years. The preoperative evaluation mainly includes ultrasonography (66%, thyroid function test (44%, and fine-needle aspiration cytology (10%. The median size of the cyst was 25 (2–60 mm. Patients mainly presented with an asymptomatic midline neck mass at or below the hyoid bone (82%, followed by fistula (9%, infection (2%, and dysphagia (2%. Eighty-nine cases were identified preoperatively as TDC. The histopathological findings confirmed TDC with hyoid bone in 61 cases, and TDC alone in 38 cases. Eighty patients underwent the Sistrunk procedure while excision of TDC alone was observed in 18 cases. Five cases of recurrent disease were also treated. Adults had a greater median cyst size (30 (9–60 vs. 22 (2–55 mm; p = 0.005 and required prolonged operation time (69 (1–169 vs. 32.5 (1–140 mins; p = 0.004 compared to the pediatric group. Conclusion: The occurrence of TDC shows a bimodal age distribution. Preoperative evaluation and time for surgery vary whereas clinical presentations, surgical management, and postoperative outcomes are comparable among adult and pediatric groups. Ultrasonography is the preferred diagnostic modality, and the

    2016-01-01

    BACKGROUND: Continuous stimulation of the androgen receptor (AR) axis is a prerequisite for growth in castration-resistant prostate cancer (CRPC). Abiraterone acetate (AA) is a potent inhibitor of extracellular and intracellular androgen synthesis by inhibition of the CYP-17 enzyme system, which...... has been shown to be up-regulated in CRPC. AA was recently introduced in the management of patients with metastatic CRPC (mCRPC) both before and after taxane-based chemotherapy. The purpose of this study is to report the initial clinical experience obtained from mCRPC patients managed on AA......% of the patients. Time to biochemical and radiological progression was 3.5 and 4.9 months, respectively. Overall survival was 13.2 months (95% CI: 9.0-17.4). CONCLUSION: Our initial experience with AA in the routine management of patients with mCRPC demonstrates an efficacy-effectiveness gap compared with clinical...

    Arterial pseudoaneurysm is an uncommon lethal complication following hepato-pancreato-biliary surgery. Aim of this study is to present and discuss the experience of a high volume oncological center. Since 2007 all major surgeries performed at Sanchinarro Oncological Center have been included in a prospective database looking for postoperative arterial pseudonaurysm. Until June 2014, among 559 hepato-pancreato-biliary procedures, a total of 14 arterial pseudoaneurysms have been identified (2.5%). Sentinel bleeding was in 57% of cases. Failed arterial embolization occurred in 2 cases. Overall mortality rate was 28.5%. We also identified 3 asymptomatic pseudoaneurysms, one of them managed without embolization, developing a sudden bleeding and died after surgery. According to our experience, pseudoaneurysm incidence is higher than reported in current literature and it can be successfully managed through arterial embolization. Furthermore, we found 3 asymptomatic pseudoaneurysms, whose management is still controversial.

    2014-12-01

    Full Text Available Objective: To propose possible success-driven solutions for problem and complication rates encountered with the ATOMS sling system, based on first-hand experience; and to provide possible actual alternative scenarios for the treatment of male . Patients and methods: During the defined period (between 4/2010 and 04/2014, 36 patients received ATOMS system implants at our clinic. We collected pre- and post-operative evaluation data using the International Consultation on Incontinence Questionnaire Short Form (ICIQ SF. As an expansion of the questionnaire, we added questions about post-operative perineal pain, the general satisfaction with the results of the intervention and willingness to recommend the operation to a best friend. Results: Our data shows a relatively high explantation rate, but a surprisingly high patient satisfaction rate. Explantation was required mainly due to late onset infections or other symptomatic factors. Compared to other studies early onset infections were rare. Conclusion: A non-invasive, uncomplicated adjustable system to alleviate male stress urinary incontinence remains a challenge. Although there are various systems available for the treatment of male stress urinary incontinence, it seems that despite the advantages of the ATOMS system, an artificial sphincter system may pose more advantages based on our experience, understanding and knowledge of its well-documented long-term solutions and problems.

    Abdominal aortic aneurysms (AAA) are rare in children and are associated with significant morbidity and mortality as in adults. We summarize our experience in the diagnosis and management of AAAs in 6 children at a single institution. The clinical data of 6 pediatric patients with AAAs treated at our hospital from November 2005 to November 2008 were retrospectively analyzed. There were 4 males and 2 females with a mean age at diagnosis of 8 years (range, 17 months to 18 years). All patients presented with pulsatile abdominal masses. Color Doppler ultrasonography and computed tomography angiography were the primary diagnostic tools. One patient has a history of tuberous sclerosis, and 1 had Takayasu's arteritis; no risk factors or identifiable causes were found in the other patients. All of the AAAs identified were infrarenal. Surgical reconstruction with aneurysm resection and prosthetic graft placement was performed successfully in all 6 cases. No intraoperative or postoperative complications occurred. Mean follow-up has been 48 months (range, 32 to 69). In 1 patient, recurrence was noted at 3 years postoperatively. The patient's family declined further surgery, and the patient died, likely of rupture of the aneurysm at 41 months postoperatively. All other patients are currently alive and well. Our experience indicates that good outcomes can be obtained in children with AAAs with prompt and accurate diagnosis and surgical management with artificial grafts.

    Chronic thromboembolic pulmonary hypertension (CTEPH) is characterized by precapillary pulmonary hypertension secondary to vaso-occlusive pulmonary vasculopathy and is classified as Pulmonary Hypertension Group 4. The aim of this study is to report the clinical experience of CTEPH in Mexico. Consecutive patients diagnosed with CTEPH were identified from the Registro de Pacientes con Hipertension Pulmonar del Instituto de Seguridad y Servicio Social de los Trabajadores del Estado (REPHPISSSTE) registry between January 2009 and February 2014. Right heart catheterization was not routinely performed prior to August 2010 in the work-up of CTEPH. We identified 50 patients with CTEPH; their median age was 63 years and 58 % were female. Patients had multiple associated co-morbidities and moderate hemodynamic impairment. All patients were treated with anticoagulation. Despite surgical evaluation for pulmonary endarterectomy (PEA), only one patient underwent PEA given the lack of infrastructure for post-operative care and lack of insurance for this procedure. Most of the patients were treated with sildenafil, bosentan, or both, with increasing use of rivaroxaban and sildenafil in recent years. The overall survival of the cohort was similar to that reported in other international registries, despite the limitations of care imposed by drug availability and surgical feasibility. This is the first report on the CTEPH experience in Mexico. It highlights the similarity of patients in the REPHPISSSTE registry to those in international registries as well as the challenges that clinicians face in a resource-limited setting.

    Background Lung transplantation (LT) is a viable option for patients with end-stage lung diseases,but in China,the supply is limited,and the experience with LT is rare too. This study aimed to evaluate the survival and postoperative complications of recipients undergone LT.Methods From January 2003 to May 2010,all patients who underwent LT were included. The clinical data of recipients were analyzed retrospectively,including demographic characteristics,survival rate,and the occurrences of postoperative complications,acute rejection and bronchiolitis obliterans syndrome. Results In total,37 patients underwent LT. The early mortality (<30 days) was 14% (5/37). Cumulative survival rate was 78%,70%,70% and 42% at 1,3,5 and 6 years,respectively. In 37 patients,5 (14%) developed fungal infections,9 (24%)pulmonary bacterial infections,and 6 (16%) had bronchial anastomosis complications after LT. At three months posttransplantation,a significant improvement was observed in lung function (P <0.05). Fifteen recipients (41%) developed acute rejection within the first year. Freedom from bronchiolitis obliterans syndrome was 89%,85% and 80% at 1,2 and 3years after transplantation.Conclusions Despite the limited number of cases,the survival and occurrences of complications after LT were comparable to the international experience. Single LT may be a reasonable option for some patients with end-stage pulmonary diseases.

    We report our initial experiences of robot-assisted cardiac surgery using the da Vinci Surgical System. Between February 2010 and March 2014, 50 consecutive patients underwent minimally invasive robot-assisted cardiac surgery. Robot-assisted cardiac surgery was employed in two cases of minimally invasive direct coronary artery bypass, 17 cases of mitral valve repair, 10 cases of cardiac myxoma removal, 20 cases of atrial septal defect repair, and one isolated CryoMaze procedure. Average cardiopulmonary bypass time and average aorta cross-clamping time were 194.8±48.6 minutes and 126.1±22.6 minutes in mitral valve repair operations and 132.0±32.0 minutes and 76.1±23.1 minutes in myxoma removal operations, respectively. During atrial septal defect closure operations, the average cardiopulmonary bypass time was 128.3±43.1 minutes. The median length of stay was between five and seven days. The only complication was that one patient needed reoperation to address bleeding. There were no hospital mortalities. Robot-assisted cardiac surgery is safe and effective for mitral valve repair, atrial septal defect closure, and cardiac myxoma removal surgery. Reducing operative time depends heavily on the experience of the entire robotic surgical team.

    Abstract: Background: Since the advent of navigational systems in neurosurgery, various implications have been introduced for them in spine and brain practices. Although, the range of surgeries in which these systems are being used is getting wider over time, their application is becoming more specific in certain situations. Methods: This means that defining specific indications for their usage is not as easy as it was previously thought. Brief reviewing of the available literature showed various navigation systems proposed and used in neurosurgery. Results: In this study, we review case selection criteria, techniques, and the results of neuronavigation applications in the patients underwent neurosurgical operations in the Sina hospital (Tehran, Iran) during 2011. Conclusions: The findings of our survey and experiences prove the efficacy and advantages of this technique that reduces the risk of neurovascular damage, neural tissue manipulation, operation time, and bleeding.

    The use of robotic surgery in the hepatobilio-pancreatic (HBP) field is still limited. Our aim is to present our early experience of robotic liver resection. A retrospective review of robotic pancreatic and liver resection was performed at Sanchinarro University hospital from October 2010 to April 2016. Since the beginning of the robotic program in our center, 22 hepatic procedures and 45 pancreatic robotic procedures have been performed. Of the 21 patients subjected to liver resection, 13 (65%) were for malignancy. There were two left hepatectomies, one right hepatectomy, one associated liver partition and portal vein ligation staged procedure (both steps by robotic approach), three bisegmentectomies and three segmentectomies, eight wedge resections, and three pericystectomies. The mean operating time was 282 min. The overall conversion rate and postoperative complication rate were 4.7 and 19%, respectively. The mean length of hospital stay was 13.4 days (range 4-64 days). Of the 45 patients subjected to pancreatic resection, 22 were male and 23 female. The average age of all patients was 62 years (range 31-82 years). The mean operating room (OR) time was 370 min (120-780 min). Among the procedures performed were 15 pancreatico-duodenectomies, 19 distal pancreatectomies, and 11 enucleations. All procedures in the HBP area were R0. Our early experience shows that robotic surgery is a safe and feasible procedure in the HBP area. The complication and mortality rates are comparable to those of open surgery, but with the advantages of minimally invasive surgery.

    We introduced laparoscopic simulator training for medical students in 2007. This study was designed to identify factors that predict the laparoscopic skill of medical students, to identify intergenerational differences in abilities, and to estimate the variability of results in each training group. Our ultimate goal was to determine the optimal educational program for teaching laparoscopic surgery to medical students. Between 2007 and 2015, a total of 270 fifth-year medical students were enrolled in this observational study. Before training, the participants were asked questions about their interest in laparoscopic surgery, experience with playing video games, confidence about driving, and manual dexterity. After the training, aspects of their competence (execution time, instrument path length, and economy of instrument movement) were assessed. Multiple regression analysis identified significant effects of manual dexterity, gender, and confidence about driving on the results of the training. The training results have significantly improved over recent years. The variability among the results in each training group was relatively small. We identified the characteristics of medical students with excellent laparoscopic skills. We observed educational benefits from interactions between medical students within each training group. Our study suggests that selection and grouping are important to the success of modern programs designed to train medical students in laparoscopic surgery.

    Hyperhemolysis is a severe and potentially life-threatening complication of transfusion described in numerous case reports and gaining recognition since 2009 via the UK Serious Hazards of Transfusion scheme. Although it is predominantly seen in patients with sickle cell disease, there are several reports of this complication in patients with other hemoglobinopathies as well as patients with a range of other hematologic diagnoses who have blood transfusions as part of their management. Our understanding of the underlying pathophysiology of this subtype of delayed transfusion reaction has increased over the last few years; however, there are still questions, which remain unanswered. In our center alone, we have encountered 9 cases in the last 5 years both in the adult and pediatric population. Here we discuss our experience in the diagnosis and management of this complication, and review other cases reported in the literature and the various existing theories behind the pathophysiology of this process. We also discuss the role of genotyping and using DNA technology to aid selection of the most appropriate blood for this patient group. With an increased awareness of hyperhemolysis, it would be advantageous to finally develop international registries to determine the true incidence of hyperhemolysis, better understand the pathophysiology, identify markers to predict which patients are at risk, and inform management guidelines.

    Full Text Available Adult living donor liver transplantations (ALDLTs across the ABO blood group barrier have been reported in Asia, North Americas, and Europe, but not yet in Germany. Several strategies have been established to overcome the detrimental effects that are attached with such a disparity between donor and host, but no gold standard has yet emerged. Here, we present the first experiences with three ABO-incompatible adult living donor liver transplantations in Germany applying different immunosuppressive strategies. Four patient-donor couples were considered for ABO-incompatible ALDLT. In these patients, resident ABO blood group antibodies (isoagglutinins were depleted by plasmapheresis or immunoadsorption and replenishment was inhibited by splenectomy and/or B-cell-targeted immunosuppression. Despite different treatments ALDLT could safely be performed in three patients and all patients had good initial graft function without signs for antibody-mediated rejection (AMR. Two patients had long-term graft survival with stable graft function. We thus propose the feasibility of ABO-incompatible ALDLT with these protocols and advocate further expansion of ABO incompatible ALDLT in multicenter trials to improve efficacy and safety.

    2014-07-01

    Full Text Available Merkel cell carcinoma (MCC is a rare malignant tumor of the skin with tendency to rapid local progression and frequent spread to regional lymph nodes. In this paper we retrospectively describe the atypical presentation of 5 cases of Merkel cell carcinoma observed in our surgical department in the last ten years. Four patients had buttock localization whilst one patient had primary nodal presentation. Since integration of Merkel cell polyomavirus (MCPyV DNA into the tumor genome is frequently recorded in this type of cancer, we analyzed formalin-fixed paraffin embedded MCC tissue samples from our five patients for the presence of MCPyV DNA by means of polymerase chain reaction (PCR. MCPyV DNA was present in all five carcinomas. All patients were treated with wide surgical excision of the tumor and sentinel node biopsy. One patient had stage I disease, three patients had stage II disease, and one patient had stage III disease. Adjuvant radiotherapy was administered in all cases for local control. Chemotherapy was administered to the patient with primary nodal presentation and in stage III disease. Median time of follow-up was 84 months. None of the patients relapsed. Despite the low number of patients examined, our experience suggests that surgery is a necessary step whereas implementation of adjuvant therapy, radiotherapy and chemotherapy depends on individual risk assessment. Treatment outcome was very good, probably due to early detection of MCC.

    Intravenous immunoglobulin (IVIG) and/or plasmapheresis (PP) are effective in preventing antibody-mediated rejection (AMR) of kidney allografts, but AMR is still a problem. This study reports our experience in living donor renal transplantation in highly sensitized patients. Ten patients with positive crossmatch tests or high levels of panel-reactive antibody (PRA) were included. Eight patients were desensitized with pretransplant PP and low dose IVIG, and two were additionally treated with rituximab. Allograft function, number of acute rejection (AR) episodes, protocol biopsy findings, and the presence of donor-specific antibody (DSA) were evaluated. With PP/IVIG, six out of eight patients showed good graft function without AR episodes. Protocol biopsies revealed no evidence of tissue injury or C4d deposits. Of two patients with AR, one was successfully treated with PP/IVIG, but the other lost graft function due to de novo production of DSA. Thereafter, rituximab was added to PP/IVIG in two cases. Rituximab gradually decreased PRA levels and the percentage of peripheral CD20+ cells. DSA was undetectable and protocol biopsy showed no C4d deposits. The graft function was stable and there were no AR episodes. Conclusively, desensitization using PP/IVIG with or without rituximab increases the likelihood of successful living donor renal transplantation in sensitized recipients. PMID:19194545

    Obstructed defecation syndrome (ODS) is a functional disorder commonly encountered by colorectal surgeons and gastroenterologists, and greatly affects the quality of life of patients from both societal and psychological aspects. The underlying anatomical and pathophysiological changes of ODS are complex. However, intra-rectal intussusception and rectocele are frequently found in patients with ODS and both are thought to play an important role in the pathogenesis of ODS. With the development of evaluation methods in anorectal physiology laboratories and radiology studies, a great variety of new operative procedures, especially transanal procedures, have been invented to treat ODS. However, no procedure has been proved to be superior to others at present. Each operation has its own merits and defects. Thus, choosing appropriate transanal surgical procedures for the treatment of ODS remains a challenge for all surgeons. This review provides an introduction of the current problems and options for treatment of ODS and a detailed summary of the essential assessments needed for patient evaluation before carrying out transanal surgery. Besides, an overview of the benefits and problems of current transanal surgical procedures for treatment of ODS is summarized in this review. A report of clinical experience of some transanal surgical techniques used in the authors’ center is also presented. PMID:27672293

    This study aimed at reviewing our experience with infections caused by Fusobacterium in children. A retrospective analysis of medical records of children admitted to Hadassah-Hebrew University Medical Center from 2000 to 2013, in whom Fusobacterium spp. was identified in any specimen. A total of 22 patients (males = 12) at a mean ± SE age of 5 ± 1 (range 1-17) years, were identified. The most common complication was abscess formation (n = 11, 50 %). Eight children (36.4 %) had intracranial complications, including brain abscess (n = 4), meningitis (n = 4) and cerebral sinus vein thrombosis (CSVT, n = 5). Seventeen children (77 %) had bacteremia. Primary site of infection was otogenic (n = 9), oropharyngeal (n = 7), respiratory (n = 2), sinuses (n = 2), intra-abdominal (n = 1) and mucositis (n = 1). Fourteen cases were caused by Fusobacterium necrophorum, including four cases with CSVT, 7/8 cases of mastoiditis, four of them with subperiosteal abscess formation; all four cases with meningitis and two brain abscesses. Fifteen (68 %) patients required surgical intervention and 3 (14 %) received anti-coagulation therapy. Excluding one patient with overwhelming sepsis with fatal outcome, all patients recovered. Fusobacterium infections in children can cause a diverse spectrum of disease and is associated with high rates of abscess formation and intracranial complications. Although Fusobacterium nucleatum is abundant in the oral cavity, F. necrophorum is the main pathogen that causes severe infections in healthy children.

    Ectopic breast tissue, which includes both supernumerary breast and aberrant breast tissue, is the most common congenital breast abnormality. Ectopic breast cancers are rare neoplasms that occur in 0.3% to 0.6% of all cases of breast cancer. We retrospectively report, using a large series of breast abnormalities diagnosed and treated, our clinical experience on the management of the ectopic breast cancer. In 2 decades, we observed 327 (2.7%) patients with ectopic breast tissue out of a total of 12,177 subjects undergoing a breast visit for lesions. All patients were classified into 8 classes, according to the classification of Kajava, and assessed by a physician examination, ultrasounds, and, when appropriate, further studies with fine needle aspiration cytology and mammography. All specimens were submitted to the anatomo-pathologist. The most frequent benign histological diagnosis was fibrocystic disease. A rare granulosa cell tumor was also found in the right anterior thoracic wall of 1 patient. Four malignancies were also diagnosed in 4 women: an infiltrating lobular cancer in 1 patient with a lesion classified as class I, and an infiltrating apocrine carcinoma, an infiltrating ductal cancer, and an infiltrating ductal cancer with tubular pattern, occurring in 3 patients with lesions classified as class IV. Only 1 recurrence was observed. We recommend an earlier surgical approach for patients with lesions from class I to IV. Copyright © 2016 Elsevier Inc. All rights reserved.

    "Domino" cardiac procedure is an effective option to increase the donor pool when heart-lung transplantation (HLT) is the only treatment for patients with terminal cardiopneumopathy. We reviewed the long-term outcomes of domino cardiac donors and recipients at our institution. Ten of 35 patients who underwent HLT from 1991 onward served as domino cardiac donors. They included eight female and two male subjects of overall mean age of 33 years and mean weight of 55 kg. Their diagnoses were primary pulmonary hypertension (n = 6) as well as cystic fibrosis, bronchiectasis, Eisenmenger's syndrome, and bronchiolitis obliterans (n = 1 each). The domino cardiac recipients included six males and four females of overall mean age of 47 years and mean weight of 61 kg. They were affected by ischemic heart disease (n = 5), cardiomyopathy (n = 4), and valvular heart disease (n = 1). Mean pulmonary vascular resistance was 3 Wood units. The heart was used either in the orthotopic (n = 8) or in the heterotopic position (n = 2). The 1-, 5-, and 10-year survivals for the domino cardiac donors versus their recipients were 60%, 40%, 30% versus 90%, 70%, 60%, respectively. Five domino donors developed bronchiolitis obliterans syndrome. Among the domino recipients group, cardiac allograft vasculopathy was rare (n = 1). Common causes of late death were in the domino recipients infections in the domino donors (n = 2) and malignancies. Our experience suggested good long-term results of the domino procedure.

    Full Text Available A well-functioning arteriovenous fistula (AVF is essential for the maintenance of hemodialysis (HD in patients with chronic renal failure. Our aim is to review our experience of creating AVF and to asses its success rate and common complication. A prospective, hospital-based study was conducted on 73 patients (48 males and 25 females on chronic HD in Gezira Hospital for Renal Diseases and Surgery, from January to July 2007. Their mean age was 43.9 years (range from 18 to 72 years. Seventy-one (97.3% of the study subjects had been dialyzed before creation of the AVF, 67 (91.8% of them having undergone HD with temporary access. All patients (n=73 had a native AVF as the permanent vascular access (VA. A primary radiocephalic AVF was created in 78.1% of the patients, cubital fossa in 20.5% and one case had left snuff box AVF (1.4%. Percentage of AVF maturation was reported in 67.1% of the cases within the first six weeks and in 9.6% of the cases AVF never matured. Failure of AVF function occurred in 26% of the cases, due to thrombosis in 20.5% (n=15 and aneurysm in 5.5% of the cases. We conclude that an optimum outcome is likely when there is a multidisciplinary team approach, and early referral to vascular surgery is paramount.

    Full Text Available Objective: To report our ureteroscopic laser lithotrip­sy experiences in the treatment of symptomatic ureter stones in pregnants which do not respond to conservative treatment Methods: A total of 6 pregnants aged between 22-33 years in second or third trimester were studied. Holmium-YAG laser lithotripsy was performed with 6.5 F semirigid uretroscope. Results: The diagnosis of ureter stone was made with ab­dominal ultrasonography in 5 patients and with magnetic resonance in one patient. Adequate stone fragmentation was performed in 2 mid-ureter and 4 distal-ureter stones. J stent was applied in one patient after the fragmenta­tion process. The mean operation time was 24.8 ± 10.0 minutes after the entry of bladder with ureteroscope un­der spinal anesthesia. No urologic, anesthetic or obstetric complication was seen and all patients gave healthy birth at term. Conclusion: Fine calibrated ureteroscopes for the treat­ment of ureter stones in pregnants are fast and effective treatment modalities which decrease the operation time and remove difficulties in entering the ureter.

    Full Text Available Purpose To present our surgical techniques and experiences of retroperitoneal laparoscopic nephroureterectomy for the treatment of tuberculous nonfunctioning kidneys. Materials and Methods From March 2005 to March 2013, a total of 51 patients with tuberculous nonfunctioning kidney underwent retroperitoneal laparoscopic nephroureterectomy at our medical center. The techniques included early control of renal vessels and dissection of the diseased kidney along the underlying layer outside the Gerato’s fascia. The distal ureter was dissected through a Gibson incision and the entire specimen was removed en bloc from the incision. Patient demographics, perioperative characteristics and laboratory parameters as well as postoperative outcome were retrospectively reviewed. Results Retroperitoneal laparoscopic nephroureterectomy was successfully performed in 50 patients, whereas one case required conversion to open surgery due to non-progression of dissection. The mean operating time was 123.0 minutes (107-160 minutes and the mean estimated blood loss was 134 mL (80-650 mL.The mean postoperative hospital stay was 3.6 days (3-5days and the mean return to normal activity was 11.6 days (10-14days. Most intra-operative and post-operative complications were minor complications and can be managed conservatively. After 68 months (12-96 months follow-up, the outcome was satisfactory, and ureteral stump syndrome did not occur. Conclusions Retroperitoneal laparoscopic nephroureterectomy as a minimally invasive treatment option is feasible for treatment of tuberculous nonfunctioning kidneys.

    Full Text Available Objective: Most cases of idiopathic nephrotic syndrome in childhood are responsive to corticosteroids. However, there is a small group of children that demonstrate steroid resistance (steroid-resistant nephrotic syndrome; SRNS, steroid dependence, or that frequently relapse (frequent-relapse steroid-sensitive nephrotic syndrome; FR-SSNS which are more clinically difficult to treat. Therefore, second-line immunosuppressants, such as alkylating agents, calcineurin inhibitors, antimetabolites and, more recently, rituximab, have been used with varying success. The objective was to evaluate the response rates of various second-line therapies in the treatment of childhood nephrotic syndrome. Study Design: A retrospective chart review of pediatric subjects with idiopathic nephrotic syndrome was conducted at a single tertiary care center (2007-2012. Drug responses were classified as complete response, partial response, and no response. Results: Of the 188 charts reviewed, 121 children were classified as SSNS and 67 children as SRNS; 58% were classified as FR-SSNS. Sixty-five subjects were diagnosed with focal segmental glomerulosclerosis via biopsy. Follow-up ranged from 6 months to 21 years. The combined rate of complete and partial response for mycophenolate mofetil (MMF was 65% (33/51 in SSNS and 67% (6/9 in SRNS. For tacrolimus, the response rate was 96% (22/23 for SSNS and 77% (17/22 for SRNS. Eighty-three percent (5/6 of SSNS subjects treated with rituximab went into complete remission; 60% relapsed after B-cell repletion. Eight refractory subjects were treated with combined MMF/tacrolimus/corticosteroid therapy with a 75% response rate. Conclusion: Our experience demonstrates that older medications can be replaced with newer ones such as MMF, tacrolimus, and rituximab with good outcomes and better side effect profiles. The treatment of refractory cases with combination therapy is promising.

    Postoperative adjuvant radiotherapy (RT) in the management of early stage endometrial cancer (EC) is still controversial. Here we report our institutional experience with patients who received postoperative RT for stage I-II EC over a period of 35 years and assess potential predictors of local recurrence (LR), distant metastasis (DM), and overall survival (OS). A total of 188 patients undergoing postoperative RT for stage IA-II EC between 1977 and 2012 were evaluated. Some 96 received median 46 Gy whole pelvic radiotherapy (WPRT) (range: 40-60 Gy), 37 were given WPRT with vaginal cuff therapy (VCT), and 55 received only VCT either with brachytherapy (BT) or stereotactic body radiotherapy (SBRT). Chemotherapy was given to 5 patients with uterine papillary serous carcinoma (UPSC). Logistic regression analysis was used to assess the effect of clinicopathological factors on LR, DM, and OS. Median follow-up time was 11 years (range: 1-35 years). At the time of analysis, 34 patients were not alive. Of the 15 patients with LR, 7 (46.7%) recurred in the vaginal stump, 5 (33.3%) in the pelvic region, and 3 (20%) in the paraaortic nodal region, while 12 had distant metastasis. UPSC histology (p=0.027), sole VCT (p=0.041), high histologic grade (p=0.034), and age≥71 (p=0.04) were poor prognostic factors on univariate analysis. In our patients receiving radiotherapy for early-stage EC, grade III disease and age≥71 were associated with shorter OS whereas UPSC histology was an independent predictor for both LR and DM.

    The aim of this study is to review our experience with sporadic pheochromocytoma in pediatrics and adolescents focusing upon surgical approach, incidence of malignancy, and recurrence rate. Between 1990 and 2007, 8 pediatric patients were diagnosed with sporadic pheochromocytoma. Demographic data, clinical and radiological findings, laboratory profile, preoperative preparation, surgical approach, operative findings, postoperative course as well as pathologic diagnosis of the removed specimen were reviewed. Mean age of presentation was 13.1 ± 4.7 years. Five patients had right-sided masses, 1 harbored left-sided mass, and bilaterality was observed in 2 with mean size of 5.7 ± 1.3 cm. Computed tomography showed no evidence of local infiltration, regional lymphadenopathy or distant metastasis in all patients but two. Six masses were excised through thoraco-abdominal approach, 3 were removed laparoscopically, while percutaneous alcohol ablation was adopted for the last. We had one postoperative death (12.5%:1/8), and the remaining 7 patients were followed for a mean of 8.6 ± 3 years. Five patients never had recurrence. Bilateral recurrence developed in 2 patients, where they were safely excised in one patient and was a part of disseminated disease in the other. Malignant nature of the disease was proved in 2 patients and showed poor survival. Under adequate anesthetic control, pediatric pheochromocytoma could be safely managed through both the open and laparoscopic approaches. Advanced radiological stage would suggest the malignant nature of the disease with dismal outcome. Long-term follow-up is warranted for possibility of delayed curable recurrence.

    Splenomegaly and pancytopenia are common in Wilson’s disease (WD) and splenectomy is one of the conventional treatments for splenomegaly and the associated pancytopenia. However, splenectomy remained controversial for hypersplenism in WD as it was reported that splenectomy leaded to serious emotional and neurological deterioration in WD patients with hypersplenism. In the current study, we present our experiences in 70 WD patients with hypersplenism who had undergone splenectomy, outlining the safety and efficacy of splenectomy in WD. The clinical database of 70 WD patients with hypersplenism who had undergone splenectomy in our hospital between 2009 and 2013 were reviewed and followed-up regularly. Before splenectomy, all the patients accepted a short period of anti-copper treatment with intravenous sodium 2, 3-dimercapto-1-propane sulfonate (DMPS). All the patients demonstrated a marked improvement in platelet and leucocyte counts after splenectomy. No severe postoperative complication was observed. In particular, none of the 37 patients with mixed neurologic and hepatic presentations experienced neurological deterioration after splenectomy, and none of the patients with only hepatic presentations newly developed neurological symptoms. During the one year follow-up period, no patient presented hepatic failure or hepatic encephalopathy, no hepatic patient newly developed neurological presentations, and only 3 patients with mixed neurologic and hepatic presentations suffered neurological deterioration and these 3 patients had poor compliance of anti-copper treatment. Quantative analysis of the neurological symptoms in the 37 patients using the Unified Wilson’s Disease Rating Scale (UWDRS) showed that the neurological symptoms were not changed in a short-term of one week after splenectomy but significantly improved in a long-term of one year after splenectomy. Additionally, compared to that before splenectomy, the esophageal gastric varices in most patients

    There has been an increase in the number of pregnancies among renal transplant recipients. Our experience included 61 pregnancies in 53 patients from January 1997 to April 2007, with 6 patients having multiple pregnancies. Patients were studied for clinical, obstetrical, and perinatal outcomes. The mean patient age was 24.5 years (range, 19-38). They all received living donor kidneys. The mean transplantation-pregnancy interval was 2.7 years (range, 1.7-5.3 years). Immunosuppressive drugs consisted of cyclosporine (CsA), mycophenolate mofetil (MMF), and prednisolone (pred) in 38 patients (72%); CsA, azathioprine (AZA), plus pred were used in 15 patients (28%). Pregnancy complications were chronic hypertension in 21 patients (40%), anemia in 28 (52.6%), and urinary tract infection in 18 (34%). Twelve patients (22.6%) received blood transfusions. Pre-eclampsia was diagnosed in 14 cases (26.4%) and renal dysfunction in 11 (20.7%) with pre-eclampsia assumed to be the main cause. Three patients (5.6%) had graft losses as a result of hemorrhagic shock, sepsis, and eclampsia. Premature rupture of membranes occurred in 6 cases (11.3%), and preterm delivery occurred in 14 cases (26.4%). Eleven (20.7%) newborns were small for gestational age. One club foot and one large facial hemangioma occurred in 2 infants, respectively. One case of neonatal death was registered as a result of excessive prematurity. One mother died due to sepsis. Cesarean section was performed in 24 patients (45.2%), the main indications being related to hypertension and fetal distress. There were no significant differences between MMF-treated and AZA-treated patients with respect to clinical, obstetrical, and perinatal outcomes. This group of patients was characterized by a wide range of antenatal and perinatal problems that must be managed in specialized tertiary units to achieve the best results. MMF may be as safe as AZA in pregnancy.

    Advances in cancer treatment allow women to be cured and live longer. However, the necessary chemotherapy and radiotherapy regimens have a negative impact on future fertility. Oncofertility has emerged as a new interdisciplinary field to address the issue of gonadotoxicity associated with cancer treatment and to facilitate fertility preservation, including oocyte and ovarian tissue cryopreservation. These fertility issues are often inadequately addressed, and referral rates to oncofertility centers are low. The aim of this study was to report the 3-year experience of the San Raffaele Oncofertility Unit. A total of 96 patients were referred to the Oncofertility Unit for evaluation after the diagnosis of cancer and before gonadotoxic treatment between April 2011 and June 2014. Of the 96 patients, 30 (31.2%) were affected by breast cancers, 20 (20.8%) by sarcomas, 28 (29.2%) by hematologic malignancies, 13 (13.5%) by central nervous system cancers, 3 (3.1%) by bowel tumors, 1 (1.0%) by Wilms’ tumor, and 1 (1.0%) by a thyroid tumor; 47 (49.0%) were referred for oocyte cryopreservation before starting chemotherapy, 20 (20.8%) were referred for ovarian tissue cryopreservation, and 29 (30.2%) were not recruited. The mean time between the patients’ counseling and oocyte retrieval was 15 days (range, 2–37 days). The mean time between the laparoscopic surgery and the beginning of treatment was 4 days (range, 2–10 days). The number of patients who were referred increased over time, whereas the rate of patients who were not recruited decreased, showing an improvement in referrals to the Oncofertility Unit and in the patients’ counseling and understanding. Our results indicate that an effective multidisciplinary oncofertility team is necessary for prompt referrals and treatment.

    Long-term patency remains a significant hurdle in the minimally invasive treatment of arteriosclerosis in the superficial femoral and popliteal arteries. New technologies designed to address the sources of restenosis have recently been introduced. CryoPlasty therapy (Boston Scientific, Natick, Mass) is a new approach designed to significantly reduce injury, elastic recoil, stent implantation, neointimal hyperplasia, and constrictive remodeling. The technique combines the dilatation forces of percutaneous transluminal angioplasty with cold thermal energy applied to the plaque and vessel wall. The cumulative effect of limiting the sources of restenosis with CryoPlasty therapy was shown to demonstrate longer term patency in a prospective, multicenter, Investigational Device Exemption study of the PolarCath Peripheral Dilatation System. The CryoPlasty therapy experience of 1 center is reported, in which 47 lesions in 32 consecutive patients (34 procedures, 33 limbs) were treated. The technical success rate was 96%. There were no type 3 flow-limiting dissections, and only 4 (8.5%) lesions were stented. There were no unanticipated adverse events, specifically no thrombus, acute occlusions, distal embolizations, aneurysms, or groin complications. With an average follow-up of 12 months, only 5 lesions have recurred, 4 requiring re-intervention. The 12-month freedom from restenosis for lesions and limbs treated was 82.2% and 84.4%, respectively. These results are similar to the findings of the Investigational Device Exemption study and are encouraging. CryoPlasty therapy appears to be a viable endovascular therapeutic option to achieve longer term patency without compromising options for future interventions. The lack of early occlusions may be due to a low rate of spiral dissection that may be a particular benefit of this form of angioplasty.

    In small infants and babies who receive split or living-related adult left lateral segmental liver grafts, further reduction (hyper-reduction) of the graft may be necessary to optimize the size of the graft for the child. We report our experience with hyper-reduction of adult left lateral segment grafts in nine children. A retrospective review of the medical records of children who received hyper-reduced grafts at the Children's Hospital at Westmead, Australia was performed. Of 215 liver transplants performed on 186 children between 1986 and May 2009, 147 were reduced grafts. Nine grafts were further reduced (hyper-reduced) after an on-table assessment of graft size relative to the available abdominal space was made. Mean graft size reduction was by 30%. The pledgetted technique of resection was used in four patients. All required delayed closure of the abdomen, and in three patients, fascial closure was not possible and a Surgisis patch (Cook Surgical International, West Lafayette, IN, USA) was placed to augment the abdominal capacity. Two children had hepatic artery thrombosis. One was successfully thrombectomized. In the other, technical problems with the donor liver contributed to death 10 days post-transplant. Two bile leaks, one from the cut surface and the other at the anastomotic site, were oversewn at the time of abdominal closure. On follow-up (median 33 months), two developed biliary strictures requiring dilatation. Hyper-reduction of segmental grafts can be safely performed when needed. In view of its versatility, it may be preferable to hyper-reduce a graft rather than use a monosegment graft. Comparable long-term results are possible. The pledgetted technique of resection is easy, quick, and safe. The fact that it can be performed after revascularization with minimal blood loss adds great flexibility to this technically challenging procedure.

Methods:Patients with endovascular aortic repair application were evaluated retrospectively. Perioperative one month mortality, additional applications during procedure, occurred complications, endoleak types, approaching anesthetical technique, diagnosis of disease, comorbid factors and demographical data registered. Results were compared with data in the literature Results: Abdominal endovascular aortic repair (EVAR applicated into 19 patients. Thoracic endovascular aor tic repair (TEVAR applicated into 11 patients. EVAR patients were operated with diagnosis of abdominal aortic aneurysm. Nine of these patients were emergely operated due to rupture. TEVAR applicated 8 patients were operated due to Type 3 Aortic Dissection and 1 patient was operated due to transsection. One month mortality of all patients were found as 10% (three atients. Endoleaks were occurred 6 patients: Three of them were Type 1a, two of them were Type1b and one of them was Type2. Balloon angioplasty applicated in two patients due to Type 1a endoleak and, in one patient due to Type 1b endoleak. Chronic renal failure was developed in one patient (3.3% due to contrast nephropathy. Reexploration was applicated in two patients (6.7% due to hematoma. Conclusion: Endovascular techniques are become frequently preferred treatment modality with the developing technology. We believed that endovascular approaches are safely preferable alternative in patients with high surgical risk as our series.

    It is generally accepted that folliculotropic mycosis fungoides (FMF) is usually typified by indurated plaques and tumors mainly on the head/neck and an aggressive course. However, its clinical manifestations have long been recognized to be quite variable, and some studies indicate a better prognosis for certain presentations. We sought to summarize our experience with the clinicopathological presentations of FMF and impact on prognosis. Data were collected retrospectively for adults with FMF followed up prospectively at a tertiary medical center in 1995 through 2014. In all, 34 patients presented with follicle-based patch/flat plaques, keratosis pilaris-like lesions, and/or acneiform lesions, defined clinically as early stage (IA, IB), and 15 presented with follicle-based infiltrated plaques and/or tumors, defined as advanced stage (IIB). The head/neck was involved in all tumor-stage cases, whereas early-stage lesions involved mainly the trunk/limbs. The tumor stage was characterized by more pruritus, heavier perifollicular infiltrates, greater vertical depth, and more frequent presence of eosinophils. On multivariate analysis, infiltrate density was the only significant histopathological discriminator between the stages. Estimated 5-year survival was 0.94 in the early-stage group and 0.69 in the tumor-stage group. Lack of long-term follow-up and relatively small sample are limitations. FMF presents with 2 distinct patterns of clinicopathologic features, early stage and advanced stage, each with different prognostic implications.

    Full Text Available Purpose: To report our early experience in image-guided chemoport insertions by interventional radiologists. Materials and Methods: This was a cross-sectional study conducted in a tertiary center with 161 chemoport insertions done from June 2008 to June 2010. The chemoports were inserted either at the angiography suite or at the mobile operation theater unit. Ninety percent of the chemoports had right internal jugular vein (IJV as the entry site. Other entry sites included the left IJV, subclavian veins and the inferior vena cava. Immediate and early complications were recorded. All insertions were performed under image guidance with the aid of ultrasound and fluoroscopy. Results: The technical success rate was 99.4%. In terms of immediate complications, there were only two cases of arterial puncture that resolved with local compression. No pneumothorax or air embolism was documented. Twenty-six early complications were recorded. The most common early complication was catheter blockage (12/161; 7.4%, followed by catheter-related infection (9/161; 5.6%. Other complications were catheter malposition, venous thrombosis and catheter dislodgement or leak. A total of 11 (6.8% chemoports had to be removed within 30 days; most of them were due to infections that failed to respond to systemic antibiotic therapy. In terms of place of procedure, there were no significant differences in complication rates between the angiography suite and the mobile operation theater unit. Conclusion: Image-guided chemoport insertion by interventional radiologist gives low periprocedural complication rates. Using right IJV as the entry site, the image guidance gives good success rate with least complication.

    Full Text Available Introduction. At the Department of Minimally Invasive Upper Digestive Surgery of the Hospital for Digestive Surgery in Belgrade, hybrid minimally invasive esophagectomy (hMIE has been a standard of care for patients with resectable esophageal cancer since 2009. As a next and final step in the change management, from January 2015 we utilized total minimally invasive esophagectomy (tMIE as a standard of care. Objective. The aim of the study was to report initial experiences in hMIE (laparoscopic approach for cancer and analyze surgical technique, major morbidity and 30-day mortality. Methods. A retrospective cohort study included 44 patients who underwent elective hMIE for esophageal cancer at the Department for Minimally Invasive Upper Digestive Surgery, Hospital for Digestive Surgery, Clinical Center of Serbia in Belgrade from April 2009 to December 2014. Results. There were 16 (36% middle thoracic esophagus tumors and 28 (64% tumors of distal thoracic esophagus. Mean duration of the operation was 319 minutes (approximately five hours and 20 minutes. The average blood loss was 173.6 ml. A total of 12 (27% of patients had postoperative complications and mean intensive care unit stay was 2.8 days. Mean hospital stay after surgery was 16 days. The average number of harvested lymph nodes during surgery was 31.9. The overall 30-day mortality rate within 30 days after surgery was 2%. Conclusion. As long as MIE is an oncological equivalent to open esophagectomy (OE, better relation between cost savings and potentially increased effectiveness will make MIE the preferred approach in high-volume esophageal centers that are experienced in minimally invasive procedures.

    Laparoscopic splenectomy (LS) is nowadays considered as the gold standard for most hematological diseases where splenectomy is necessary, but many questions still remain. The aim of this study was to analyze our 5-years experiences consisting of 48 consecutive LS cases in order to assess the optimal approach and the feasibility of the procedure also in malignant diseases and unusual cases such as a primary spleen lymphoma, a big splenic artery aneurism, or a spleen infarct due to a huge pancreatic pseudo-cyst. Forty-eight consecutive patients underwent LS from January 2006 to January 2011 with at least 1-year follow-up. Clinical data and immediate outcome were retrospectively recorded; age, diagnosis, operation time, perioperative transfusion requirement, conversion rate, accessory incision, hospital stay, and complications were analyzed. We had 14 cases of malignant splenic disease, the most frequent malignant diagnosis was non-Hodgkin's lymphoma (12/14, 85.7 %). Splenomegaly (interpole diameter (ID) >20 cm) was observed in 12 cases (25 %) and massive splenomegaly (ID >25 cm) in 3 cases (6.25 %). Conversion to laparotomy occurred in two patients (4.16 %), both associated to uncontrollable bleeding in patients with splenomegaly. Mean operative time was 138 ± 22 min. Mean hospital stay was 4.5 days. Postoperative morbidity rate was 8.8 % for the benign group and 35.7 % in the malignant group. Mortality occurred in 1/48 patients (2.08 %), as a result of overwhelming post-splenectomy infection (OPSI). LS can be performed safely for malignant splenic disease and splenomegaly without any statistically significant increase of morbidity and mortality rate. Conversion rate is increased for massive splenomegaly. LS should be considered as the preferential approach even in patients with malignant disease, splenomegaly, or unusual cases. Massive splenomegaly should be considered as relative contraindication to LS even at experienced centers.

    Since May 1992 the Medtronic Open Pivot mechanical heart valve has been implanted routinely at the authors' institution. The study aim was to analyze, retrospectively, the 20-year clinical results of the valve. Between May 1992 and December 2011 a total of 1,520 valves was inserted into 1,382 consecutive patients (1,012 aortic, 473 mitral, 26 tricuspid, 9 pulmonary). The mean age of the patients was 61±13.2 years. Preoperatively, 65% of the patients were in New York Heart Association (NYHA) class III or greater. Frequent comorbidities included atrial fibrillation (n=419), coronary disease (n=357), and diabetes (n=255). The 99% complete follow-up totaled 10,527 patient-years (range 12 to 244 months). Ninety-day mortality was 5.2% (n=73, 8 valve related). Of the 550 total deaths, 240 were cardiac and 56 valve related. Multivariate analysis selected age, NYHA III or greater, concomitant coronary revascularization, and respiratory insufficiency as risk factors for death. Renal failure was considered a risk factor in the aortic and atrial fibrillation in the mitral subgroup. Erratic international normalized ratio (INR), NYHA class III or greater, and non-sinus rhythm were risk factors for thromboembolism; likewise redo operations in the aortic subgroup. Erratic INR and age were risk factors for bleeding as were over-coagulation and coronary revascularization in the aortic subgroup and redo operations and renal failure in mitral patients. This 20-year experience demonstrated excellent clinical outcomes with no structural valve failure. Odds ratio defined aortic patients as the lowest risk for adverse events. By contrast atrial fibrillation and elderly age, in combination with instable anticoagulation, yielded the worst long-term results. Copyright © 2014 The Society of Thoracic Surgeons.

    Liver transplant is a definite treatment of decompensated liver disease. Because of the shortage of livers from deceased donors, living-donor liver transplant is becoming more common. Here, we analyzed our clinical experience in the follow-up care of these patients. Liver transplant recipients seen at the Sindh Institute of Urology and Transplantation (Karachi, Pakistan) were included in this analysis. Baseline characteristics and follow-up events were recorded. Our study population included 76 liver transplant patients registered at our clinic. Median age was 42 years, with 62 patients (81.6%) being males. The most common indication of transplant was hepatitis C virus-related cirrhosis (42 patients; 55%), followed by hepatitis B-hepatitis D virus coinfection (8 patients; 10.5%). Anastomotic biliary stricture developed in 16 patients (21.1%),which required biliary stenting. Biliary leak developed in 5 patients (6.6%), and renal cell carcinoma developed in 1 patient. Two recipients died due to hepatitis C virus-related fibrosing cholestasis hepatitis and pulmonary com plications. Posttransplant diabetes mellitus developed in 36 (47.1%), hypertension in 17 (38.6%), and dyslipidemia in 19 patients (25%). Of 42 patients with hepatitis C virus infection, 26 were treated with pegylated interferon and ribavirin, of which 65.3% achieved sustained virologic response at 24 weeks. The other 16 patients received sofosbuvir com - bined with ribavirin for 24 weeks. A sustained virologic response at 12 weeks was achieved in 5 patients, with not yet determined results in the remaining patients. Seven patients were lost to follow-up. Hepatitis C-related cirrhosis was the most common indication for liver transplant, and infection recurrence was observed in our patients. Biliary anastomotic stricture formation was the most prevalent complication after transplant. As liver transplants are becoming more widely available for Pakistani patients at home and abroad, gastroenterologists and

    Traumatic internal carotid artery dissection (CAD) has a potentially grave outcome. Anticoagulant therapy may be ineffective or contraindicated; surgery impractical. We present our experience with endovascular stenting in CAD patients. From 2004 to 2011, 23 patients with angiographically proven traumatic CAD underwent endovascular stent-assisted arterial reconstruction based on clinical and radiographic criteria: contraindication or failure of anticoagulation, evidence of impending ischemic stroke, or need for urgent intracranial revascularization. Dissections were graded based on degree of stenosis and extent of injury. Seventeen patients (73.9%) presented with stroke or transient ischemic attack. Carotid revascularization was achieved with one (11 patients, 48%) or multiple stents (12 patients, 52%); distal protection was used rarely (three patients, 13%). No complications were directly attributed to stenting. Mean dissection-related stenosis improved from 72% ± 28.87% to 4% ± 8.29%. At a mean clinical follow-up of 28.7 months ± 31.9 months, 16 patients (69.6%) improved, six (26.1%) remained stable, and one (4.3%) had died secondary to multiple traumatic injuries. At long-term follow-up, no patient had a transient ischemic attack or stroke or presented evidence of de novo in-stent stenosis or stent thrombosis. There were no neurologic sequelae after partial or total discontinuation of antiplatelet therapy in seven patients undergoing trauma-related surgeries. Selected cases of traumatic CAD can be safely managed by endovascular stent-assisted angioplasty. Procedural complications are infrequent; the need for postprocedure antiplatelet therapy is a concern. Early detection is essential to avoid stroke. Stenting restores the integrity of the vessel lumen immediately, efficiently prevents the occurrence or recurrence of ischemic events, and avoids the need of long-term anticoagulation.

    Full Text Available Background and Purpose: Posterior inferior cerebellar artery (PICA like other intracranial arteries is prone to aneurysm formation. Aneurysms usually arise from the vertebral artery (VA - PICA junction and the proximal segment of the PICA. The use of endovascular treatment as an alternative treatment to surgery has been increasing. We present our last 5 years experience in treating the ruptured proximal PICA aneurysms. Materials and Methods: Retrospective analysis of records of all patients with ruptured VA-PICA junction aneurysms treated at our referral center between July 2008 and July 2013 was performed. Over the last 5 years, we came across 17 patients who had aneurysms of proximal PICA or VA-PICA junction out of which 13 patients underwent endovascular treatment for ruptured saccular VA-PICA junction aneurysms and were the focus of this research. Follow-up studies ranged from 6 months to 3 years. Results: All the patients presented with an acute intracranial hemorrhage on NCCT. All the aneurysms were at VA-PICA junction with partial or complete incorporation of PICA origin in the sac. Endovascular treatment of all the 13 aneurysm was successful in the first attempt. Aneurysms were treated with balloon assisted coiling either by placing the balloon across the VA-PICA junction (n = 3 or in the vertebral artery proper (n = 9. Stent assisted coiling VA-PICA was performed in one aneurysm (n = 1. There was no intra-procedural rupture of the aneurysms. Conclusion: Endovascular therapy of ruptured proximal PICA aneurysms is possible and safe with the use of adjuvant devices and should be considered as first line treatment.

    Full Text Available Food induced sensitization has been reported in pediatric liver recipients. However long term follow up has not been established so far. We report here our experience regarding 3 pediatric patients who developed acquired food allergy after liver transplantation. The first patient suffered from persistent diarrhea and eczema. The second one presented with abdominal pain with no signs of rejection, abdominal discomfort, vomiting when ingesting milk proteins and responded well to the elimination diet. The third patient presented with facial angioedema and hoarseness of voice. She had multiple food allergies and reacted to milk, egg and sesame. All the patients had elevated total Immunoglobulin E (IgE and elevated specific IgE antibodies to the implicated food allergens. The first patient presented clinical manifestations of allergy when she was 19 months old. The second patient became allergic at the age of 16 and the third patient at the age of 3. The symptoms of food allergy persisted for 8 years in the first case and for 2 years in the other two cases. Low levels of specific IgE antibodies to the implicated food allergens and an enhanced T-helper 1 cell immune response toward interferon-gamma production were markers of tolerance acquisition. The long term prognosis in our cases was excellent. Food allergy resolved in all the patients. The long term prognosis of acquired food allergy after liver transplantation is currently obscure. More studies would be needed including greater number of patients to determine whether acquired food allergy is transient in pediatric liver recipients.

    Background Orthotopic liver retransplantation (re-OLT) is the only effective therapy for irreversible failure of a liver graft. Early and late graft failure gives way to two different clinical conditions that should be discussed separately. This study was designed to compare early and late re-OLT for patients with poor graft function after primary transplantation at our center and sum up our clinical experience in re-OLT.Methods The clinical data of 31 re-OLTs at our center from January 2004 to February 2007 were analyzed retrospectively, consisting of the first group with 14 cases of early re-OLT and the second group with 17 cases of late re-OLT.Results Biliary tract complications were the main indications for early re-OLT (57.1%) and late re-OLT (52.9%). Other common indications were vascular complications in early re-OLT and recurrence of primary diseases in late re-OLT. No significant differences were found between the groups with regard to the volume of bleeding during operation, cold ischemia time, operative duration, and perioperative mortality; except for the model of end-stage liver disease (MELD) score. Outcome was fatal for 7 patients in early re-OLT and 9 patients in late re-OLT. Two deaths were due to multiple organ failure with 3 deaths due to severe sepsis-related disease in early re-OLT, and 4 deaths were due to severe sepsis-related disease with 3 deaths due to recurrence of hepatocellular carcinoma (HCC) in late re-OLT. One and 2-year actuarial survival rates after re-OLT were 55.2% and 36.9%, respectively, for patients in early re-OLT, and 65.1% and 52% respectively, for patients in late re-OLT. No significant differences were found regarding survival rates between the two groups.Conclusions Similar clinical results can be achieved in early and late re-OLT. Proper indications and optimal operation timing, adequate preoperative preparation, experienced surgical procedures, and effective perioperative anti-infection strategy contribute to the

    Background For patients with end-stage lung diseases, lung transplantation is the final therapeutic option. Sequential double-lung transplantation is recognized as an established procedure to avoid cardiopulmonary bypass (CPB). But some of the sequential double-lung transplantations require CPB support during the surgical procedure for various reasons. However, conventional CPB may increase the risk of bleeding and early allograft dysfunction. Extracorporeal membrane oxygenation (ECMO) is more advantageous than conventional CPB during the perioperative period of transplantation. Replacing traditional CPB with ECMO is promising for those patients needing cardiopulmonary support during a sequential double-lung transplantation procedure. This study aimed to summarize the preliminary experience of ECMO practice in lung transplantation.Methods Between November 2002 and October 2008, twelve patients with end-stage lung diseases undergoing sequential double-lung transplantation were subjected to ECMO during the surgical procedure. Eleven patients were prepared were prepared for the procedure via transverse thoracostomy (clamshell) and cannulated through the ascending aorta and right atrium for ECMO. The first patient who underwent bilateral thoracotomy for bilateral sequential lung transplantation required emergency ECMO via the femoral artery and vein during the second lung implantation. The Medtronic centrifugal pump and ECMO package (CB1V97R1, Medtronic, Inc., USA) were used for all of the patients.Results During ECMO,the blood flow rate was set between 1.88-2.0 L·m~(-2)·min~(-1) to keep hemodynamic and oxyhgen saturation stable; colloid oncotic pressure was maintained at more than 18 mmHg with albumin and hematocrit (HCT) kept at 28% or more. Two patients died early in this series and the other 10 patients were weaned from ECMO successfully. The duration of ECMO was 1.38-67.00 hours, and postoperative intubation was 10.5-67.0 hours.Conclusions As an established

    Objective This study aimed to report our experiences with surgical repair in patients of all ages with persistent truncus arteriosus. Methods From July 2004 to July 2014, 50 consecutive patients with persistent truncus arteriosus who underwent anatomical repair were included in the retrospective review. Median follow-up time was 3.4 years (range, 3 months to 10 years). Results Fifty patients underwent anatomical repair at a median age of 19.6 months (range, 20 days to 19.1 years). Thirty patients (60%) were older than one year. The preoperative pulmonary vascular resistance and mean pulmonary artery pressure were 4.1±2.1 (range, 0.1 to 8.9) units.m2 and 64.3±17.9 (range, 38 to 101) mmHg, respectively. Significant truncal valve regurgitation was presented in 14 (28%) patients. Hospital death occurred in 3 patients, two due to pulmonary hypertensive crisis and the other due to pneumonia. Three late deaths occurred at 3, 4 and 11 months after surgery. The actuarial survival rates were 87.7% and 87.7% at 1 year and 5 years, respectively. Multivariate analysis identified significant preoperative truncal valve regurgitation was a risk factor for overall mortality (odds ratio, 7.584; 95%CI: 1.335–43.092; p = 0.022). Two patients required reoperation of truncal valve replacement. One patient underwent reintervention for conduit replacement. Freedom from reoperation at 5 years was 92.9%. At latest examination, there was one patient with moderate-to-severe truncal valve regurgitation and four with moderate. Three patients had residual pulmonary artery hypertension. All survivors were in New York Heart Association class I-II. Conclusions Complete repair of persistent truncus arteriosus can be achieved with a relatively low mortality and acceptable early- and mid-term results, even in cases with late presentation. Significant preoperative truncal valve regurgitation remains a risk factor for overall mortality. The long-term outcomes warrant further follow-up. PMID:26752522

    favoring the diagnosis. The management of PTLD poses a major therapeutic challenge and although there is reasonable agreement about the overall principles of treatment, there is still considerable controversy about the optimal treatment of individual patients. EBV-related PTLDs are a significant cause of mortality in patients undergoing orthotopic liver transplantation with the observed mortality rate of up to 50%. This paper presents the experience acquired at Merkur University Hospital in the diagnosis and treatment of patients with liver transplantation and PTLD.

    Over the past 20 years our policy has been to electively repair common atrioventricular canal defects (CAVCD) in patients between 8 and 12 weeks of age. We sought to evaluate the results of our past 20-year experience. From January 1992 to April 2014, 159 consecutive patients underwent CAVCD repair (133 patients had complete CAVCD and 26 patients had a transitional form of CAVCD). Surgical repair was accomplished with a double-patch (n = 137 [86%]) or a modified single patch (n = 22 [14%]) technique. Median age at operation was 96 days (interquartile range [IQR], 73-128 days); 90 patients were younger than 3 months of age. There were 3 operative (1.9%) and 12 late (7.7%) deaths. Median follow-up time after repair was 8.2 years (IQR, 3.6-15 years). Twenty patients (13%) required reoperation-16 (10%) for left atrioventricular valve (LAVV) regurgitation. Reoperation on the LAVV was more frequent in patients with a dysplastic LAVV preoperatively (p = 0.01; odds ratio [OR], 4.2; 95% confidence interval [CI], 1.33-13.5) and in patients who underwent closure for an absent/incomplete cleft at the time of repair (p = 0.01; OR, 5.4; 95% CI, 1.4-21). Late LAVV performance (regurgitation greater than or equal to moderate or the need for reoperation), including late deaths and patients who underwent reoperation, was significantly worse in patients older than 3 months at repair (10 of 83 patients [12%] versus 20 of 73 patients [27%]; hazard ratio [HR], 2.71; 95% CI, 1.19-6.19) and in patients with LAVV dysplasia (19 of 68 patients [28%] versus 11 of 88 patients [12%]; HR, 3; 95% CI, 1.53-8.51). Individualized early repair of CAVCD is safe and beneficial, with good early and long-term results. Copyright © 2016 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

Median follow-up time was 3.4 years (range, 3 months to 10 years.Fifty patients underwent anatomical repair at a median age of 19.6 months (range, 20 days to 19.1 years. Thirty patients (60% were older than one year. The preoperative pulmonary vascular resistance and mean pulmonary artery pressure were 4.1±2.1 (range, 0.1 to 8.9 units.m2 and 64.3±17.9 (range, 38 to 101 mmHg, respectively. Significant truncal valve regurgitation was presented in 14 (28% patients. Hospital death occurred in 3 patients, two due to pulmonary hypertensive crisis and the other due to pneumonia. Three late deaths occurred at 3, 4 and 11 months after surgery. The actuarial survival rates were 87.7% and 87.7% at 1 year and 5 years, respectively. Multivariate analysis identified significant preoperative truncal valve regurgitation was a risk factor for overall mortality (odds ratio, 7.584; 95%CI: 1.335-43.092; p = 0.022. Two patients required reoperation of truncal valve replacement. One patient underwent reintervention for conduit replacement. Freedom from reoperation at 5 years was 92.9%. At latest examination, there was one patient with moderate-to-severe truncal valve regurgitation and four with moderate. Three patients had residual pulmonary artery hypertension. All survivors were in New York Heart Association class I-II.Complete repair of persistent truncus arteriosus can be achieved with a relatively low mortality and acceptable early- and mid-term results, even in cases with late presentation. Significant preoperative truncal valve regurgitation remains a risk factor for overall mortality. The long-term outcomes warrant further follow-up.

    After extensive experimentation, outcomes of a first clinical normothermic machine perfusion (NMP) liver trial in the United Kingdom demonstrated feasibility and clear safety, with improved liver function compared with standard static cold storage (SCS). We present a preliminary single-center North American experience using identical NMP technology. Ten donor liver grafts were procured, four (40%) from donation after circulatory death (DCD), of which nine were transplanted. One liver did not proceed because of a technical failure with portal cannulation and was discarded. Transplanted NMP grafts were matched 1:3 with transplanted SCS livers. Median NMP was 11.5 h (range 3.3-22.5 h) with one DCD liver perfused for 22.5 h. All transplanted livers functioned, and serum transaminases, bilirubin, international normalized ratio, and lactate levels corrected in NMP recipients similarly to controls. Graft survival at 30 days (primary outcome) was not statistically different between groups on an intent-to-treat basis (p = 0.25). Intensive care and hospital stays were significantly more prolonged in the NMP group. This preliminary experience demonstrates feasibility as well as potential technical risks of NMP in a North American setting and highlights a need for larger, randomized studies. © 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Full Text Available Acute kidney injury (AKI is becoming more prevalent among hospitalized children, its etiologies are shifting, and new treatment modalities are evolving; however, diarrhea-associated hemolytic uremic syndrome (D+HUS remains the most common primary disease causing AKI in young children. Little has been published about acute renal replacement therapy (ARRT and its challenges in this population. We describe our single center's experience managing 134 pediatric patients with D+HUS out of whom 58 (43% required ARRT over the past 16 years. In our cohort, all but one patient were started on peritoneal dialysis (PD. Most patients, 47 (81%, received acute PD on a pediatric inpatient ward. The most common recorded complications in our cohort were peritoneal fluid leaks 13 (22%, peritonitis 11 (20%, and catheter malfunction 5 (9%. Nine patients (16% needed surgical revision of their PD catheters. There were no bleeding events related to PD despite a mean platelets count of 40.9 (±23.5 × 103/mm3 and rare use of platelets infusions. Despite its methodological limitations, this paper adds to the limited body of evidence supporting the use of acute PD as the primary ARRT modality in children with D+HUS.

    Controversial evidence exists regarding the laparoscopic approach in patients with acute appendicitis complicated with peritonitis due to a higher rate of surgical complications. The aim of this study was to compare post-operatory outcomes in patients with acute appendicitis complicated exclusively with peritonitis approached by laparoscopy versus open surgery. Single center retrospective analysis of clinical records of patients with appendicitis complicated with peritonitis operated from January 2003 until October 2013. Demographic data, intra-operative variables, length of stay, surgical complications, mortality, readmissions and reoperations were retrieved. 227 patients were identified, 43% males, mean age 39±17 years (range: 12-85 years). Ninety-seven patients (43%) underwent laparoscopic appendectomy, 13 of them were converted to open surgery (13%). Ninety-four patients presented with diffuse peritonitis (41.4%). Laparoscopic appendectomy showed longer operative time but shorter hospital stay (pperitonitis. In our experience, laparoscopic appendectomy is a safe approach in cases of appendicitis complicated exclusively with peritonitis. Copyright © 2014 Surgical Associates Ltd. Published by Elsevier Ltd.

    High-grade craniofacial osteosarcoma (CFOS) is an aggressive malignancy with a poor prognosis. Our goals were to evaluate treatment outcomes in those treated at a single referral institution over 35 years and to compare our results to the available literature. A retrospective analysis of all 42 patients treated between 1980 and 2015 at Oslo University Hospital, Norway, identified in a prospectively collected database, was conducted. Mean follow-up was 79.6 months. Overall survival at 2 and 5 years was 70.5 and 44.7%, respectively. The corresponding disease-specific survival rates were 73.0 and 49.8%. Treatment was surgery only in eight cases. Additional therapy was administered in 34 patients: chemotherapy in nine, radiotherapy in seven, and a combination of these in 18 cases. Stratified analysis by resection margins demonstrated significantly better survival at 2 and 5 years after radical surgical treatment. Neoadjuvant chemotherapy and subsequent adequate surgery resulted in better survival than surgery alone. Half of the patients either had a primary or familial cancer predisposition. This is the largest single-center study conducted on high-grade CFOS to date. Our experience indicates that neoadjuvant chemotherapy with complete surgical resection significantly improved survival, compared to surgery alone.

    Objective: The aim of our retrospective study was to review our single-center experience with aortic abdominal aneurysm (AAA) repair retrospectively. Material and methods: From 1995 to 2005, 70 consecutive patients affected by AAA were treated by endovascular stent-graft repair. Mean follow-up was 23.9 months. Follow-up investigations were performed at 6 and 12 months and yearly thereafter. Five different stent-graft designs were compared to each other. Primary technical success (PTS), assisted primary technical success (APTS), primary clinical success (PCS) and secondary clinical success (SCS) were evaluated. Results: All over PTS was achieved in 94.3%, APTS in 97.1%, PCS in 61.4%, APCS in 64.3% and SCS in 70%. There were 3 type I endoleaks, 25 type II endoleaks, 4 type III endoleaks, 8 limb problems, 5 conversions to open surgery, 10 aneurysm sac expansions and 14 device migrations. Patients with newer generation devices showed better results than patients with first generation prosthesis. In addition results were better for grafts with suprarenal fixation (versus infrarenal fixation) and grafts with barbs and hooks (versus grafts without barbs and hooks). Patients with bad anatomic preconditions showed a higher complication rate. Conclusion: Contrary to first generation products, new stent-graft designs show acceptable technical and clinical results in endovascular AAA aneurysm repair. However, this therapy still should be reserved only for patients with significant comorbities and suitable anatomic conditions.

    We aimed to evaluate the effectiveness of the endourologic management of forgotten and/or encrusted ureteral stents together with our single-center experience. Fifty-four patients with forgotten double-J ureteral stents were treated in our center between January 2008 and March 2014. Encrustation and the related stone burdens were estimated by using computerized tomography and kidney-ureter-bladder radiography. The management method was chosen based on the stone burden or clinical and radiological findings. Fifty-four patients, 39 males and 15 females, were included in the study. The average age of the patients was 38.2 ± 25.06 (2-86) years. The average indwelling time of the ureteral stents was 22.6 ± 30.3 (6-144) months. Six of the patients with forgotten stents had solitary kidneys. The double-J stent (DJS) was fragmented in four (7.4%) patients. A urinary system infection was present in 15 (27.7%) of the patients. The ureteral stents and related stones were successfully removed without any complications by combined endourologic techniques to achieve a stone-free state in all patients except for patient with 110 months of forgotten stent time in whom nephrectomy was performed for a nonfunctioning kidney related to the forgotten stent. Forgotten/encrusted DJS may lead to complications in a range of urinary system infections, up to a loss of renal function. They can be safely and successfully removed, and the renal function can be preserved by endourologic techniques, starting with the least invasive procedures in centers highly experienced.

    Peritoneal dialysis (PD) is an underutilized form of renal replacement therapy. Although a variety of factors have been deemed responsible, timely insertion of a PD catheter may also be a contributory factor. Furthermore, a good catheter implantation technique is important to allow for effective peritoneal access function and long-term technique survival. Studies regarding results obtained by nephrologists in comparison with surgeons have been limited to small single-center experiences. Thus, the objective of this study was to explore the impact of the peritoneal dialysis (PD) catheter insertion by nephrologists compared to surgeons on early catheter complications and on technique survival. We also examine whether PD catheter insertion by nephrologists has a positive impact on the growth in the number of patients using PD. We performed 313 consecutive procedures: 192 catheter insertions and 121 catheter removal from January 1, 2006 to December 31, 2013. The main reasons for catheter removal were: renal transplantation, 52 (43%) follow of transfer to HD, 48 (40%) and catheter malfunction, 16 (13%). The patients were mostly male (63.4%) with the mean age of 50.8±15.1 years and 23.8 were diabetics. We only observed seven (2.5%) early complications (<4 weeks) associated to peritoneal catheter surgery (3 peritonitis episodes, 2 hemoperitoneum episodes, one complicated hernia and one omental entrapment). There were not significant differences in surgery-related complications in both periods. The penetration ratio of PD after 2006 was 117% higher compared with procedures performing before this date. In conclusions, we have demonstrated a positive impact on the growth of the PD population when catheter insertion is performed by nephrologists with a minimal incidence of complications associated.

    The role of image-guided thermal ablation techniques for the nonoperative local management of painful osseous metastatic disease has expanded during recent years, and several advantages of cryoablation in this setting have emerged. The purpose of this study is to retrospectively evaluate and report a single-center experience of CT-guided percutaneous cryoablation in the setting of painful musculoskeletal metastatic disease. This study was approved by the institutional review board and is compliant with the Health Insurance Portability and Accountability Act. Electronic medical records of all patients who underwent percutaneous image-guided palliative cryoablation at our institution were reviewed (n = 61). An intent-to-treat analysis was performed. Records were reviewed for demographic data and anatomical data, primary tumor type, procedure details, and outcome - including change in analgesic requirements (expressed as morphine equivalent dosages), pain scores (utilizing the clinically implemented visual analog scale), subsequent therapies (including radiation and/or surgery), and complications during the 24 h following the procedure and at 3 months. Patients were excluded (n = 7) if data were not retrospectively identifiable at the defined time points. Fifty-four tumors were ablated in 50 patients. There were statistically significant decreases in the median VAS score and narcotic usage at both 24 h and 3 months (p < 0.000). Six patients (11 %) incurred complications related to their therapy. Two patients had no relief at 24 h, of which both reported worsened pain at 3 months. One patient had initial relief but symptom recurrence at 3 months. Four patients went on to have radiation therapy of the ablation site at some point following the procedure. CT-guided cryoablation is a safe, effective, reproducible procedural option for the nonoperative local treatment of painful musculoskeletal metastatic disease. (orig.)

    Treatment of chronic hepatitis C virus (HCV) infection remains a priority in the veterans affairs (VA) health care system nationwide, as there is a high burden of liver disease due to HCV infection among US veterans. The combination of sofosbuvir and simeprevir was the first all-oral antiviral regimen used in clinical practice to treat veterans with HCV infection. In this study, we report a single-center experience showing both the feasibility and effectiveness of this all-oral combination to treat HCV genotype 1 infection. One hundred patients with HCV genotype 1 infection were treated between December 2013 and June 2014. Eighty-six patients were treated with sofosbuvir and simeprevir, with or without ribavirin, for 12 weeks; 12 patients were treated with sofosbuvir, pegylated interferon, and ribavirin for 12 weeks; and 2 patients were treated with sofosbuvir and ribavirin for 24 weeks. Overall, treatment was well tolerated and feasible, with compliance rates over 95% in patients treated with all-oral therapy. The sustained virologic response (SVR) rate for sofosbuvir and simeprevir (88.4%) was superior to the rate for sofosbuvir, pegylated interferon, and ribavirin (50.0%). Subgroup analysis showed diminished SVR rates in cirrhotic patients vs noncirrhotic patients. There were no significant differences in SVR when comparing treatment with or without ribavirin or among genotype subtypes. In conclusion, this study demonstrated excellent completion rates for all-oral treatment of veterans with chronic HCV infection. Additionally, treatment was highly effective, nearing a 90% cure rate. Thus, we recommend that the VA health care system continue to incorporate new HCV medications into its formulary so as to expand HCV treatment for US veterans.

    Background: Transcatheter closure of congenital coronary artery fistulas (CCAFs) is an alternative therapy to surgery; however, data regarding transcatheter closure for CCAF with a giant coronary artery aneurysm (CAA) in pediatric patients are still limited due to the rarity of the disease. We aimed to evaluate the efficacy and safety of transcatheter closure for CCAF with a giant CAA in a pediatric population at a single center. Methods: Medical records of pediatric patients (aneurysm dilation after the second intervention. One patient experienced thrombus formation within the CAA after the procedure. Among those with closure at the entry point of the CAA, a mild-to-moderate residual shunt was detected in three patients. Conclusions: Transcatheter closure appears to be a safe and effective alternative therapy for CCAF with a giant CAA in the pediatric population. Closure at the entry point of the CAA, and closure at both the entry and exit points when feasible, may reduce the risk of postinterventional complications. PMID:28776543

    Purpose To assess the determinants of technical failure of magnetic resonance (MR) elastography of the liver in a large single-center study. Materials and Methods This retrospective study was approved by the institutional review board. Seven hundred eighty-one MR elastography examinations performed in 691 consecutive patients (mean age, 58 years; male patients, 434 [62.8%]) in a single center between June 2013 and August 2014 were retrospectively evaluated. MR elastography was performed at 3.0 T (n = 443) or 1.5 T (n = 338) by using a gradient-recalled-echo pulse sequence. MR elastography and anatomic image analysis were performed by two observers. Additional observers measured liver T2* and fat fraction. Technical failure was defined as no pixel value with a confidence index higher than 95% and/or no apparent shear waves imaged. Logistic regression analysis was performed to assess potential predictive factors of technical failure of MR elastography. Results The technical failure rate of MR elastography at 1.5 T was 3.5% (12 of 338), while it was higher, 15.3% (68 of 443), at 3.0 T. On the basis of univariate analysis, body mass index, liver iron deposition, massive ascites, use of 3.0 T, presence of cirrhosis, and alcoholic liver disease were all significantly associated with failure of MR elastography (P technical failure rate of MR elastography with a gradient-recalled-echo pulse sequence was low at 1.5 T but substantially higher at 3.0 T. Massive ascites, iron deposition, and high body mass index were additional independent factors associated with failure of MR elastography of the liver with a two-dimensional gradient-recalled-echo pulse sequence.

    Permanent AV-block is a recognized and feared complication of slow pathway modulation for AVNRT. We aimed to assess incidence of transient and permanent AV-block as well as consequences of transient AV-block in a large contemporary AVNRT ablation cohort. We searched our single center prospective ablation database for occurrence of transient and permanent AV-block during slow pathway modulation between January 2004 and October 2015. We analyzed patients' and procedural characteristics as well as outcome of patients in whom transient or permanent AV-block occurred. Of 9170 patients who underwent a catheter ablation at our institution between January 2004 and October 2015, 2101 patients (64% women, mean age 50±18years) underwent slow pathway modulation. In three patients, permanent AV-block occurred during RF application. Additional two patients had transient AV-block that recovered (after a few minutes and 25min), but recurred within two days of the procedure. All five patients underwent dual chamber pacemaker implantation (0.2%). Transient AV-block related to RF delivery occurred in 44 patients (2%). Transient mechanical AV-block occurred in additional 17 patients (0.8%). In 12 patients, ablation was continued despite transient AV-block. One of these patients developed permanent AV-block. Permanent AV-block following slow pathway modulation is a rare event, occurring in 0.2% of patients in a large contemporary single center cohort. Transient AV-block is more frequent (2%).

    To evaluate the efficacy, tolerability, and compliance of 3 ketogenic diets, the classical ketogenic diet, medium-chain triglyceride (MCT), and modified Atkins diet. A single-center, retrospective study of 48 children with intractable epilepsy receiving ketogenic diets from 2003 to 2012. Patient demographics, epilepsy history, nutritional management, and side effects were collated. Compliance and tolerability were assessed by recording reasons for diet modification and cessation. The value of potassium citrate supplementation for preventing nephrolithiasis was reviewed. Median age at ketogenic diet initiation was 3.8 years (IQR: 2.3-7 years). The majority had intractable epilepsy, and 33 of the 48 children (69%) had epileptic encephalopathies. Three (6%) patients became seizure free, 35 (73%) reported Diet duration or ketogenic diet type did not predict reduction in seizures (P = .381; P = .272). Constipation (n = 31, 65%) was very common. Food refusal (n = 3, 6%) and poor parental compliance (n = 5, 10%) were common reasons cited for cessation. There were lower rates of side effects for modified Atkins diet. Diet cessation was greatest for MCT; however, 3 patients on MCT ceased therapy because adequate seizure control was achieved. Nephrolithiasis was reported in 1 patient before potassium citrate was used and 2 patients noncompliant with potassium citrate supplementation developed hypercalciuria. The 3 ketogenic diets were comparably effective in seizure control and generally well-tolerated. Potassium citrate supplementation is an effective prophylactic supplement for the prevention of nephrolithiasis. Crown Copyright © 2015. Published by Elsevier Inc. All rights reserved.

    Full Text Available Gaucher disease, a lysosomal storage disorder, is a multisystem disorder with variable and unpredictable onset and severity. Disease-specific enzyme replacement therapy (ERT has been shown to reverse or ameliorate disease-specific hepatosplenomegaly and anemia and thrombocytopenia. ERT also impacts bone manifestations, including bone crises, bone pain, and appearance of new osteonecrosis, and improves bone mineral density to varying degrees. The objective of this study was to assess achievement of predefined therapeutic goals based on international registry outcomes for Israeli patients with Gaucher disease receiving imiglucerase for four consecutive years on a low-dose regimen followed in a single center. All data were taken from patient files. The therapeutic goals were taken from standards published in the literature for disease-specific clinical parameters. Among 164 patients at baseline, values for spleen and liver volumes, hemoglobin and platelet counts, and Z-scores for lumbar spine and femoral were significantly different from the goal. After four years ERT, there was a significant improvement ( in each of the therapeutic goal parameters from baseline. 15.2% of these patients achieved all hematology-visceral goals. In children, there was achievement of linear growth and puberty. This survey highlights the good overall response in symptomatic patients receiving low-dose ERT with imiglucerase in Israel.

    The purpose of this study was to compare three different biopsy devices on false-negative and underestimation rates in MR-guided, vacuum-assisted breast biopsy (VABB) of MRI-only lesions. This retrospective, single-center study was IRB-approved. Informed consent was waived. 467 consecutive patients underwent 487 MR-guided VABB using three different 8-10-gauge-VABB devices (Atec-9-gauge,A; Mammotome-8-gauge,M; Vacora-10-gauge,V). VABB data (lesion-type, size, biopsy device, histopathology) were compared to final diagnosis (surgery, n = 210 and follow-up, n = 277). Chi-square, and Kruskal-Wallis tests were applied. P values < 0.05 were considered significant. Final diagnosis was malignant in 104 (21.4 %), high risk in 64 (13.1 %) and benign in 319 (65.5 %) cases. Eleven of 328 (3.4 %) benign-rated lesions were false-negative (1/95, 1.1 %, A; 2/73, 2.7 %, M; 8/160 5.0 % V; P = 0.095). Eleven high-risk (11/77, 14.3 %) lesions proved to be malignant (3/26, 11.5 % A; 4/12, 33.3 % M; 4/39, 10.3 % V; P = 0.228). Five of 34 (14.7 %) DCIS were upgraded to invasive cancer (2/15, 13.3 %, A; 1/6, 16.6 % M; 2/13, 15.3 %, V; P = 0.977). Lesion size (P = 0.05) and type (mass vs. non-mass, P = 0.107) did not differ significantly. MR-guided VABB is an accurate method for diagnosis of MRI-only lesions. No significant differences on false-negative and underestimation rates were observed between three different biopsy devices. (orig.)

Previous fetal studies reported survival rates of ≤ 25% for patients with intended postnatal care. Clinical data and echocardiograms of 12 cases with a fetal diagnosis of APVS between 2000 and 2010 were analyzed in this retrospective single-center study. Collected parameters included: gestational age at referral, associated fetal abnormalities, cardiothoracic ratio, maximum diameters of pulmonary annulus and main and branch pulmonary arteries, ventricular dimensions and function as well as ventricular Doppler flows. Karyotyping included fluorescence in-situ hybridization (FISH) analysis for microdeletion 22q11.2. Median gestational age at diagnosis was 24 weeks. Three subtypes of APVS were observed: (1) with tetralogy of Fallot (TOF) and no arterial duct (n = 10; 83%); (2) isolated, with a large arterial duct (n = 1; 8%); and (3) with tricuspid atresia, right ventricular dysplasia and a restricted duct (n = 1; 8%). The cardiothoracic ratio and pulmonary artery dimensions were increased in all cases. The karyotype was abnormal in 70% of fetuses with TOF and their mortality rate was significantly higher due to pregnancy termination (n = 3) or perinatal demise (n = 2) (hazard ratio, 5; 95% CI, 0.87-28.9; P = 0.015). Of seven live births with active postnatal care, six children (86%) were alive without residual respiratory symptoms at a median follow-up of 4.7 (range, 2.1-10.6) years. Outcome after fetal diagnosis of APVS was significantly better in this study compared with those of previous fetal series, with a low mortality rate for actively managed patients.

    Purpose To describe the incidence, clinical courses, and risk factors for mortality of lower respiratory tract diseases (LRDs) caused by common respiratory viruses (CRVs) in stem cell transplantation (SCT) recipients. Materials and Methods We retrospectively reviewed the medical records of 1038 patients who received SCT between January 2007 and August 2011 at a single center in Korea. Results Seventy-one CRV-LRDs were identified in 67 (6.5%) patients. The human parainfluenza virus (HPIV) was the most common causative pathogen of CRV-LRDs at 100 days [cumulative incidence estimate, 23.5%; 95% confidence interval (CI), 3.3–43.7] and 1 year (cumulative incidence estimate, 69.2%; 95% CI, 45.9–92.5) following SCT. The 30-day overall mortality rates due to influenza-LRDs, respiratory syncytial virus-LRDs, HPIV-LRDs, and human rhinovirus-LRDs were 35.7, 25.8, 31.6, and 42.8%, respectively. Co-pathogens in respiratory specimens were detected in 23 (33.8%) patients. The overall mortality at day 30 after CRV-LRD diagnosis was 32.8% (22/67). High-dose steroid usage (p=0.025), a severe state of immunodeficiency (p=0.033), and lymphopenia (p=0.006) were significantly associated with death within 30 days following CRV-LRD diagnosis in a univariate analysis. Multivariate logistic regression analysis revealed that high-dose steroid usage [odds ratio (OR), 4.05; 95% CI, 1.12–14.61; p=0.033] and lymphopenia (OR, 6.57; 95% CI, 1.80–24.03; p=0.004) were independent risk factors for mortality within 30 days of CRV-LRDs. Conclusion CRV-LRDs among SCT recipients showed substantially high morbidity and mortality rates. Therefore, the implement of an active diagnostic approaches for CRV infections is required for SCT recipients with respiratory symptoms, especially those receiving high-dose steroids or with lymphopenia.

    Endoscopic submucosal dissection (ESD) of early gastric neoplasia has not yet been established in Western countries because of a lack of data and the difficult, time-consuming, and hazardous nature of the method. Some of the technical limitations may be overcome by use of a water jet-assisted knife, which allows a combination of a high-pressure water jet and electrosurgical interventions. To evaluate the efficacy and safety of water jet-assisted ESD (WESD) with a water jet-assisted knife in selected patients with early gastric neoplasia. Single-center, prospective study. This study involved 29 consecutive patients (13 female; median age 61 years; age range 35-93 years) with early gastric neoplasia that met the expanded criteria of the Japanese Gastric Cancer Association. Histology of biopsies had shown gastric adenocarcinoma in 21 cases, adenoma in 8 case, and suspicion of a GI stromal tumor in 1 case. The median maximal diameter of the lesions was 20 mm (range 10-40 mm). All procedures were done with patients under sedation with propofol. The water jet-assisted knife was used for setting coagulation markers around the neoplastic lesions, then for circumferential incision and dissection in combination with repeated submucosal injection of saline solution with a water jet system. Bleeding was treated with diathermia by use of the water jet-assisted knife or hemostatic forceps in case of failure or larger vessels. Clips were used for closure of perforations. Complete resection of neoplasia, procedure time, complication and recurrence rates. According to endoscopic criteria, complete resection of the targeted area could be achieved in all cases, with an en bloc resection rate of 90%. The median procedure duration was 74 minutes (range 15-402 minutes). Exchange of the device was needed in only 10 cases because of severe bleeding from larger vessels, which could be managed by use of hemostatic forceps. The 30-day morbidity rate was 4 of 30 (13.8%) because of

    INTRODUCTION: A recent single-center report indicated that the performance of atrial fibrillation ablation in patients on uninterrupted warfarin using a conventional deflectable tip electrode ablation catheter may be as safe as periprocedural discontinuation of warfarin and bridging with heparin. Novel multi-electrode array catheters for atrial fibrillation ablation are currently undergoing clinical evaluation. While offering the possibility of more rapid atrial fibrillation ablation, they are stiffer and necessitate the deployment of larger deflectable transseptal sheaths, and it remains to be determined if they increase the risk of cardiac perforation and vascular injury. Such potential risks would have implications for a strategy of uninterrupted periprocedural anticoagulation. METHOD AND RESULTS: We audited the safety outcomes of our atrial fibrillation ablation procedures using multi-electrode array ablation catheters in patients on uninterrupted warfarin (CHADS2 score>or=2) and in patients not on warfarin (uninterrupted aspirin). Two bleeding complications occurred in 49 patients on uninterrupted warfarin, both of which were managed successfully without longterm sequelae, and no bleeding complication occurred in 32 patients not on warfarin (uninterrupted aspirin). There were no thromboembolic events or other complication with either anticoagulant regimen. CONCLUSION: Despite the larger diameter and increased stiffness of multi-electrode array catheters and their deflectable transseptal sheaths, their use for catheter ablation in patients with atrial fibrillation on uninterrupted warfarin in this single-center experience does not appear to be unsafe, and thus, an adequately powered multicenter prospective randomized controlled trial should be considered.

    Full Text Available Background/Aim. Selective intraarterial radionuclide therapy (SIRT with Yttrium-90 (Y-90 microspheres is also known as radioembolization and delivers high doses of radiation to hepatic tumors with minimum healthy liver exposure. The aim of this study was to present our preliminary experience in the role of liver directed radiotherapy with Y-90 microspheres for the treatment of unresectable hepatic metastases from neuroendocrine tumors (NET. Methods. The results of SIRT in 10 patients (5 males, 5 females; mean age 48.7 years; age range 24-73 years with metastatic liver disease from NETs during the period from April 2008 through August 2010 were reviewed. All patients had meticulous pre- and post-imaging studies as a part of their work-up procedure, as well as serologic tests of liver function to determine the extent of liver function damage. The patients who were eligible for SIRT had pretreatment visceral angiography to define and occlude non-target arteries. Results. The mean ± SD administered SIR-Spheres® activity was 1.49 ± 0.42 GBq (range 0.72-2.21 GBq in all the patients. These treatments delivered a dose of 99.73 ± 66.36 Gy (range 49- 420.8 Gy to the target tumors. The estimated dose to the lungs and normal liver was 4.45 ± 1.95 Gy (range 2.4-8.5 Gy and 26.73 ± 14.19 Gy (range 5-58.9 Gy, respectively. Overall response rate of 90% and patient tolerance was satisfactory for most patients. Conclusion. From our limited experience, we can conclude that SIRT with Y-90 microspheres is a safe and efficacious treatment option for patients with liver metastasis of NET without any serious side effects.

    Gallstones and cholelithiasis are being increasingly diagnosed in children owing to the widespread use of ultrasonography. The treatment of choice is cholecystectomy, and routine intraoperative cholangiography is recommended to explore the common bile duct. The objectives of this study were to describe our experience with the management of gallstone disease in childhood over the last 18 years and to propose an algorithm to guide the approach to cholelithiasis in children based on clinical and ultrasonographic findings. The data for this study were obtained by reviewing the records of all patients with gallstone disease treated between January 1994 and October 2011. The patients were divided into the following 5 groups based on their symptoms: group 1, asymptomatic; group 2, nonbiliary obstructive symptoms; group 3, acute cholecystitis symptoms; group 4, a history of biliary obstructive symptoms that were completely resolved by the time of surgery; and group 5, ongoing biliary obstructive symptoms. Patients were treated according to an algorithm based on their clinical, ultrasonographic, and endoscopic retrograde cholangiopancreatography (ERCP) findings. A total of 223 patients were diagnosed with cholelithiasis, and comorbidities were present in 177 patients (79.3%). The most common comorbidities were hemolytic disorders in 139 patients (62.3%) and previous bariatric surgery in 16 (7.1%). Although symptoms were present in 134 patients (60.0%), cholecystectomy was performed for all patients with cholelithiasis, even if they were asymptomatic; the surgery was laparoscopic in 204 patients and open in 19. Fifty-six patients (25.1%) presented with complications as the first sign of cholelithiasis (eg, pancreatitis, choledocolithiasis, or acute calculous cholecystitis). Intraoperative cholangiography was indicated in 15 children, and it was positive in only 1 (0.4%) for whom ERCP was necessary to extract the stone after a laparoscopic cholecystectomy (LC).

    Full Text Available We present our first experience with endovascular treatment of 6 subclavian artery aneurysms (SAA occurring in five male and one female patient. All patients, in our studies, according to ASA classification were high risk for open repair of SAA. The etiology of the all aneurysms was atherosclerosis degeneration of the artery. Two aneurysms were of intrathoracic location, then the other were extrathoracic. Symptoms related to subclavian artery aneurysms were present in two patients, compression and chest pain in one, and hemorrhage shock in second, while the remaining patients were asymptomatic. We preferred the Viabhan endoprosthesis for endovascular repair in 5 cases. In one patient with ruptured of subclavian artery aneurysm who was high-risk for open repair we made combined endovascular procedure. First at all, we covered the origin of left subclavian artery with thoracic stent graft and after that we put two coils in proximal part of subclavian artery. There was no operative mortality, and the early patency rate was 100%. The follow-up period was from 3 months to 3 years. During this period, one patient died of heart failure and one patient required endovascular reoperation due to endoleak type I. Endovascular treatment is recommended for all patients with subclavian artery aneurysm whenever this is possible due to anatomical reasons especially in high-risk patient with intrathoracic localization of aneurysm, to prevent potential complications.

    AIM: To report our experience with long-term outcomes after multimodal management therapy. METHODS: An observational retrospective study was performed containing seven patients with hepatoblastoma (Hbl) treated in our institution, a tertiary referral center, from 2003 to 2011. Demographic, preoperative, surgical, and outcome variables were collected. A survival analysis and a review of the current literature related to combination neoadjuvant chemotherapy and surgical resection on Hbl were performed. RESULTS: The median age at surgery was 14.4 mo, with a male to female ratio of 4:3. Pretext staging at diagnosis was as follows: stage I, 4 cases; stage II, 2 patients; and stage III, 1 case. Mean pretreatment tumor volume was 735 cm3. Five out of seven patients received neoadjuvant chemotherapy according to SIOPEL-3 or SIOPEL-6 protocols. Tumor volume and alpha-fetoprotein levels significantly dropped after neoadjuvant therapy. Surgical procedures performed included hemihepatectomies, segmentectomies and atypical resection. All patients received chemotherapy after surgery. Median postoperative hospital stay was 8 d. All patients were alive and disease-free after a median follow-up period of 23 mo. With regards to the literature review, seventeen articles were found that were related to our search. CONCLUSION: Our series shows how multimodal management of Hbl, exhaustive control and a meticulous surgical approach leads to almost 100% complete resection with optimal postoperative results.

    Mitochondrial respiratory chain disorder (MRCD) can cause liver failure requiring liver transplantation (LT), although it is often difficult to diagnose before LT. From 2005 to 2016, 9 MRCD patients with the median age at LT of 6 months underwent LT in our institute. Their clinical courses were retrospectively reviewed and the laboratory parameters were compared between the MRCD patients and 10 patients with acute liver failure unrelated to MRCD (non-MRCD). Five patients had extrahepatic manifestations, including developmental disorders in 3 and failure to thrive in 3, before LT. Only 3 patients (33.3%) were diagnosed before LT. Between MRCD and non-MRCD, lactate was significantly high and lactate-to-pyruvate ratio (L/P ratio) tended to be higher in MRCD. From the receiver operating characteristic curve, the optimal cutoff value of lactate was 50.0 mg/dL and that of L/P ratio was 23.2. Patient survival rate of MRCD was 77.8%, although 2 patients with mitochondrial depletion syndrome suffered from de novo pulmonary hypertension after LT. Our experiences showed the difficulty of preoperative diagnosis, and preoperative extrahepatic manifestations did not always mean poor outcome. Our study showed that lactate value and L/P ratio can be excellent predictors of MRCD. Copyright © 2017 Elsevier Inc. All rights reserved.

    Volume mismatch is encountered when a single live donor cannot provide adequate graft volume to the recipient with a remnant liver volume which is safe for donation. Our objective is to present our experience in living donor liver transplantation using dual grafts. Record review of 4 dual graft recipients was done. The results were compared with 122 consecutive patients who received a single right lobe. All dual graft recipients were surviving with satisfactory liver function at a median follow-up of 21 months. Two recipients received 1 right and 1 left lobe graft, while the other 2 recipients received 2 left lobe grafts. One donor developed biloma and was managed by percutaneous drainage. The first recipient required re-laparotomy for postoperative bleeding. The second recipient underwent re-laparotomy for bile leak. The third recipient developed grade II decubitus ulcers due to a prolonged sedentary position. When compared with recipients who received a single right lobe, the operative time was prolonged in the dual graft group. There was no apparent increase in the rate of vascular and biliary complications or the incidence of acute cellular rejection. Actuarial patient survivals were comparable in both groups. Dual graft transplantation provides sufficient volume in the recipient without jeopardizing donor safety.

    Resection and reconstruction of infiltrated vessels achieve resectability of extended pancreatic tumors. The aim of the present study was to assess the feasibility of bovine pericardium as graft material for the individualised portal vein reconstruction and demonstrate a surgical technique for abdominal vein repair. We performed a MEDLINE search to review the methods for complex abdominal vein reconstruction in the course of extended pancreatectomy. Moreover, clinical data of patients receiving portal vein reconstruction using a bovine pericardial patch at our institution were retrospectively analyzed. Based on the results of a review of the literature, autologous venous grafts using the internal jugular vein represent the most popular option for segmental portal vein reconstruction in case of impossible direct suture. At our center, segmental portal vein reconstruction with bovine pericardial patch in course of pancreatic surgery was performed in 4 patients. No case of vascular complications such as occlusion, segmental stenosis or thrombosis occurred. Our experience suggests a surgical procedure for an individual size-matched portal vein reconstruction using bovine pericardium. Although first results appear promising, prospective studies are required to objectively assess the patency of bovine pericardium compared with autologous and synthetic interposition grafts for portal vein reconstruction. © 2015 S.

    Gastrointestinal stromal tumors (GIST) are mesenchymal tumors of the gastrointestinal tract supposed to arise from the cells of Cajal because of gain-of-function mutations of the tyrosine receptor kinases c-kit or platelet-derived growth factor receptor A. Imatinib selectively inhibits the kinase activity of both receptors. Despite this breakthrough in the treatment of GIST, resistance against imatinib has been reported to be as high as 50% after the first 2 years of treatment. Outcome of 13 consecutive patients with relapsed or metastasized GIST who were treated with imatinib was analyzed. Mean duration of treatment was 53.5 months. Four patients developed progressive disease and died after a mean treatment time of 31 months in spite of increase of imatinib dosages to 800 mg daily. Two patients (23%) developed a progressive disease after 46 months or 52 months of treatment. Two patients had a stable disease and five had a partial response. The overall progression rate was 46%, the mean survival time since primary diagnosis was 85.8 months. From our experience, frequency of resistance development to imatinib may be below that given in the literature (50% after 2 years). Individual treatment in specialized centers may improve compliance.

    AIM: To share our surgical experience and the outcome of limited pancreatic head resection for the management of branch duct intraductal papillary mucinous neoplasm (IPMN). METHODS: Between May 2005 and February 2008, nine limited pancreatic head resections (LPHR) were performed for IPMN of the pancreatic head. We reviewed the nine patients, retrospectively. RESULTS: Tumor was located in the uncinate process of the pancreas in all nine patients. Three patients had stents inserted in the main pancreatic duct due to injury. The mean size of tumor was 28.4 mm. Postoperative complications were found in five patients: 3 pancreatic leakages, a pancreatitis, and a duodenal stricture. Pancreatic leakages were improved by external drainage. No perioperative mortality was observed and all patients are recorded alive during the mean follow-up period of 17.2 mo. CONCLUSION: In selected patients after careful evaluation, LPHR can be used for the treatment of branch duct type IPMN. In order to avoid pancreatic ductal injury, pre- and intra-operative definite localization and careful operative techniques are required.

    Full Text Available Hematopoietic stem cell transplantation (HSCT is the only potentially curative treatment for patients with thalassemia major. However, only 30-35% of patients have a suitable HLA-matched family donor (MFD. We report herewith our experience with matched unrelated donor (MUD HSCT using a treosulfan based conditioning protocol, from a tertiary center in India. The cohort consisted of 25 children (18 boys and 7 girls with transfusion-dependent thalassemia major who were transplanted using matched or minimally mismatched unrelated donors over four years with a median follow-up of 12 months (range 2–36 months. The median age of the cohort at HSCT was five years. None of the children transplanted had graft rejection. Reactivation of cytomegaloviral infection occurred in 32% of children. Grade II-IV acute graft versus host disease (aGvHD occurred in 60% of the children. Of these, two (8%, succumbed to aGvHD. Chronic extensive GvHD was not observed in any of the children until the last follow-up. The probability of survival at a mean of 34.3 months (CI 31.2–37.4 months for those who underwent a fully HLA-matched unrelated donor HSCT was 95%. This data shows that if the donor selection is based on strict compatibility criteria, MUD-HSCT can offer a cure to children with thalassemia major, with outcomes similar to the MFD-HSCT.

    Full Text Available Objective: To analyze the perioperative outcome of the first 190 cases of robot-assisted laparoscopic radical prostatectomy performed at our center from July 2006 to December 2010. Materials and Methods: Operative and recovery data for men with localized prostate cancer undergoing robot-assisted radical prostatectomy at our center were reviewed. All surgeries were performed using the 4-arm da Vinci-S surgical robot. Preoperative data included age, body mass index (BMI, prostate specific antigen (PSA level, prostate weight, biopsy Gleason score and TNM staging, while operative and recovery data included total operative time, estimated blood loss, complications, hospital stay and catheter time. These parameters were evaluated for the safety and efficacy of this procedure in our center. Results: The mean age of our patients was 65 ± 1.2 years. The mean BMI was 25.20 ± 2.88 and the median PSA was 14.8 ng/ml. Majority of our patients belonged to clinical stage T2 (51.58%. The mean total operative time was 166.44 ± 11.5 min. Six patients required conversion to open procedure and there was one rectal injury. The median estimated blood loss was 302 ± 14.45 ml and the median duration of hospital stay was 4 days. The overall margin positivity rate was 12.63%. Conclusion: Despite our limited robotic surgery experience, our perioperative outcome and complication rate is comparable to most contemporary series. Robot-assisted laparoscopic prostatectomy (RALP is easy to learn and provides the patient with the benefits of minimally invasive surgery with minimal perioperative morbidity.

    We investigated obstetric outcomes and comorbidities during pregnancy in females with preexisting lupus nephritis (LN) and identified predictors for renal flare. In cases of renal flare during pregnancy, we assessed the long-term post-delivery renal outcome. We performed a retrospective analysis of 183 systemic lupus erythematosus (SLE) pregnancies including blood chemistry, urinalysis, urinary protein, and disease activity recorded at prepregnancy, during pregnancy, and at one month, six months, and one year post-delivery. Pregnancies with preexisting LN had a greater frequency of adverse obstetric outcomes and maternal comorbidity. Renal flares occurred in 50.7% of pregnancies with preexisting LN, 89.2% of which were reactivations. Renal flare among pregnancies with SLE was predicted based on preexisting lupus nephritis (OR 17.73; 95% CI, 5.770-54.484), an active disease prior to pregnancy (OR 2.743; 95% CI, 1.074-7.004), and prepregnancy eGFR pregnancies. The median follow-up time after delivery was 5.9 (3.1-9.7) years and chronic kidney disease (CKD) occurred in 21.4% of pregnancies with renal flare. In patients with renal flare, failing to achieve a ≥ 50% reduction in urine protein levels within six months, longer total duration of renal flare, and acute kidney injury at renal flare was associated with CKD development. Females with preexisting LN should achieve remission before pregnancy. When patients experience renal flares during pregnancy, it is important to reduce the proteinuria level by >50% within six months and to achieve early remission for excellent long-term renal outcomes.

    To present early experience with foetoscopic endotracheal occlusion (FETO) for congenital diaphragmatic hernia (CDH) in a new center in Poland. This was a prospective study in singleton pregnancies with CDH treated by FETO between 2014 and 2016 in the Medical University of Warsaw, Poland. FETO was carried out at 25.6-30.1 (median 27.7) weeks' gestation in 28 consecutive cases of isolated left-sided CDH with observed over expected lung area to head circumference ratio (o/e LHR) of 20.7-22.6 (median 18.9). Neonatal survival rate was 46.4% (13/28) at the time of discharge. The median o/e LHR the day before balloon removal was 33.4 (19.7-57.5) and median gestational age at delivery was 34.7 (29.0-38.1) weeks. Comparison of the survivors and perinatal deaths showed no significant differences in median gestational age at FETO or median o/e LHR before FETO, but higher median gestational age at delivery (35.9, range 32.7-38.1 weeks vs. 33.2, range 29.0-37.7 weeks; p = .007) and o/e LHR before balloon removal (33.7, range 28.3-57.5 vs. 30.9, range 19.7-37.5; p = .017). FETO was implemented successfully in Poland and the survival rate (46.4%) is similar to that reported in other centers. Important determinants of survival were gestational age at delivery and pulmonary response to FETO. The rate of preterm prelabor rupture of membranes (PPROM) in our series is similar to the larger series treated with FETO in the pioneering centers of this technique.

    Aim: Ear reconstruction is a challenge for plastic and reconstructive surgeons. The ear requires sufifcient skin coverage and a three-dimensional (3D) cartilage framework. In this paper, the authors present their 10-year experience in microtia reconstruction using tissue expansion and an autogenous rib cartilage framework.Methods: Ear reconstruction was performed in 3 operative stages. During the ifrst procedure, a 50-80 mL kidney or cylinder-shaped expander was implanted deep to the subcutaneous fascia of the retroauricular mastoid region. Over a period of 3-5 months, the expander was iflled to a ifnal volume of 80-110 mL. In the next operation, the retroauricular fascia was eliminated or reserved following expander removal, and the autogenous costal cartilage framework was placed below the expanded skin lfap. At the third and ifnal stage, the earlobe transposition, tragus construction and conchal deepening were performed.Results:A total of 165 patients (166 ears) were reconstructed using tissue expansion and an autogenous rib cartilage framework. Complications included hematomas in 3 cases, expander exposure in 8 cases, cartilage exposure in 6 cases, infection and cartilage resorption in 2 cases, exposure of steel wire in 4 cases, and aseptic seroma in 2 cases. Follow-up ranging from 3 months to 5 years showed that 159 patients were satisifed with the reconstructed ear including size, location, projection, convolution, skin-colour matching, symmetry with opposite ear.Conclusion:Expansion of the retroauricular skin and fascia can provide sufifcient non-hair-bearing skin and tissue for coverage of a three-dimensional costal cartilage framework. Avoidance and prompt treatment of complications are advised in order to obtain a satisfactory reconstruction of the ear.

    Cerebral dural arteriovenous fistulas (DAVFs) are rare intracranial vascular lesions but can cause significant morbidity and mortality. To analyze the effect of the center's experience on DAVF embolization efficacy and safety. From May 2008 to October 2014, 57 embolization procedures were attempted on 48 patients (37 men and 11 women; median age: 63.9 years) for DAVF in a single center. DAVF presented with cortical venous reflux in 44/48 cases (91.7%) and hemorrhagic manifestation in 21/48 cases (43.75%). Angiographic occlusion quality, whether complete or incomplete (efficacy), and neurological complications (safety) were recorded. The patient population was divided into four consecutive quartiles during the inclusion period to assess the progress profile. Efficacy and safety outcomes were compared with Fisher's test. A logistic regression was performed to explore a learning curve phenomenon, showing a significant association between the chronological rank in the cohort and embolization efficacy (P=0.007). Significant differences were found between first and last quarter (P=0.036). The endovascular technique involved an arterial injection of Onyx(®) in 36/48 cases (75%), administered via the middle meningeal artery in 25/36 cases (69.5%). The complete occlusion rate improved significantly from 33.3% for the first quartile of the population, to 75.0% for the 2nd and 3rd quartiles and 83.3% for the last quartile. Neurological complications were found in 7/48 patients (14.6%), the rate decreased by 41.7% to 16.7%, without statistically difference. The efficacy and safety of DAVF embolization improved with the experience gained at the center, suggesting the existence of a learning curve. Copyright © 2016 Elsevier Masson SAS.

    Background: Percutaneous nephrostomy (PCN) has been established as an effective technique for urinary decompression or diversion. This procedure may be performed with the guidance of fluoroscopy, ultrasonography, a combination of fluoroscopy and ultrasonography, computed tomography (CT), or magnetic resonance imaging. Purpose: To retrospectively review experience with CT-guided PCN over a 10-year period in a single center. Material and Methods: All CT-guided PCN procedures performed in adults at our institution between 1995 and 2005 were evaluated. In 882 patients, 1113 nephrostomy catheters were inserted. Interventional radiologists or radiology residents under direct attending supervision inserted all catheters. During the PCN procedure, bleeding, sepsis, and injuries to adjacent organs were regarded as major complications. Clinical events requiring nominal therapy with no sequelae were regarded as minor complications. Results: PCN procedures were performed via 1-3 punctures in patients with grades 0-1 and 2 hydronephrosis, and via 1-2 punctures in patients with grade 3 hydronephrosis. They were carried out with a procedure time ranging from 9 to 26 min. All PCNs were considered as technically successful, and no major complications were observed. There were minor complications including transient macroscopic hematuria (28.6%, 19.9%, and 4.9% in patients with hydronephrosis grades 0-1, 2, and 3, respectively) and perirenal hematomas in a total of eight patients. No patient required additional intervention secondary to complications of the PCN procedure. Conclusion: CT-guided PCN is an efficient and safe procedure with major and minor complication rates below the accepted thresholds. It can be used for the management of patients requiring nephrostomy insertion in inpatient settings, and might be a preferable procedure in patients with minimal or no dilatation of the renal pelvis.

    The use of covered stent grafts during percutaneous coronary intervention (PCI) is a life saving solution to seal acute iatrogenic vessel rupture. However, the presence of an impenetrable mechanical barrier is also appealing during treatment of friable coronary plaques but the synthetic PTFE-membrane that might trigger excessive neointimal proliferation has limited its elective-use. Pericardium tissue may offer an appealing "natural" alternative. Aim of our study is to report the consecutive 5-year single center experience with the use of pericardium-covered stents (PCS) (ITGI-Medical, Israel) in a variety of emergency and elective applications. Nineteen consecutive patients undergoing implantation of PCS at the Royal Brompton in the last 5-years. Reasons for PCS implantation included treatment of degenerated vein grafts, large coronary aneurysms, and acute iatrogenic vessel rupture. Angiographic success, defined as the ability of the device to be deployed in the indexed lesion with no contrast extravasation with residual angiographic stenosis <30% and a final thrombolysis in myocardial infarction (TIMI)-3 flow was achieved in all cases. Procedural success, defined as the achievement of angiographic success without any major adverse cardiovascular event (MACE) was achieved in 94.7% of patients. In-stent restenosis (ISR) was observed in 26.3% and all patients underwent successful target vessel revascularization with DES (mean time to restenosis 9.0 ± 4.0 months). At a mean follow-up of 32.5 ± 23.3 months no acute or late stent thrombosis was observed. PCSs were effective in the treatment of friable embolization-prone coronary plaques, sealing of acute iatrogenic vessel rupture and exclusion of large aneurysms with no thrombosis but high target lesion revascularization. © 2015 Wiley Periodicals, Inc.

    We aimed to present the outcomes of PNL surgery performed in infantile patients with small renal stones who were younger than 1 year of age. A single-center prospective trial was initiated and during the period between Jan 2013 and Jan 2015, PNL was applied to 20 renal units of 16 infants (6 girls and 10 boys), including 4 patients with bilateral kidney stones. PNL was performed in patients with renal stones larger than 2 cm, as well as stones resistant to SWL or renal stones that were undetectable during SWL. The mean age of the patients was 9.55 (5-12) months. Of the 20 renal units, 1 had complete staghorn stones, 3 had partial staghorn stones, 13 had renal pelvic stones, and 3 had lower pole stones. The mean stone size was 18.5 mm (range 12-36 mm). Mean operative time for PNL was 88 (25-135 min). Mean fluoroscopy time was estimated as 3.4 min. Mean hemoglobin loss was 0.72 g/L (0.2-3). The mean hospital stay was 4.1 days (2-8 days). On postoperative day 1, a complete stone-free state was achieved in 70% of renal units (14 of 20). At the end of the first postoperative week, the remaining two patients had insignificant residual fragments of 3 mm and were followed conservatively without any specific intervention. Thus, the total SFR was 80% (16 of 20) at discharge. In infants aged less than 1 year, minimal access tract dilation during PNL, the use of smaller caliber pediatric instruments, and the realization of this procedure by surgeons with adequate experience in adults carry utmost importance. In addition, special care should be taken to avoid hypothermia and radiation exposure during PNL.

    Purpose: Abdominal aortic aneurysm (AAA) accompanied by common iliac artery (CIA) aneurysms requires a more demanding procedure owing to the difficulties in obtaining an adequate distal landing zone for the stent-graft limb(s), a potential site of endoleak. The 'sandwich technique' is a procedure to increase EVAR feasibility in the setting of adverse or challenging CIA anatomy. Its main advantages include no restrictions in terms of CIA diameter or length or internal iliac artery (IIA) diameter, no need to wait for a specific stent-graft. Our purpose is to describe our single-center experience and one year follow-up results of this new procedure. Materials and Methods: From April 2009 to June 2010, the sandwich technique was performed in our institution in 7 patients treated for AAA and unilateral CIA aneurysms (n. 5) or bilateral CIA aneurysms (n. 2). Inclusion criteria were the presence of unilateral or bilateral CIA aneurysm (independently from its diameter), IIA artery measuring up to 9 mm in its maximum diameter, not dilatation of IIA and EIA. Results: The mean follow-up length was 15 months (range: 14-20 months). All stent-implanted iliac branches remained patent on 1 year follow-up and IIA flow was preserved. None of the patients had symptoms of pelvic ischemia. CT scan follow-up showed aneurysm shrinkage in five patients, without any sign of endoleaks in all cases. Conclusions: In selected cases, the 'sandwich technique' showed good outcomes confirming to be a safe and easy to perform way to overcome anatomical constraints and expanding the limits of EVAR.

    Warm autoimmune hemolytic anemia (wAIHA) is a rare autoimmune disease with poorly known natural history and management remaining mainly empirical. To better describe the characteristics and outcome of wAIHA in adults, we performed a single-center cohort study of patients diagnosed with wAIIHA from 2001 to 2012 in our center. Sixty patients (50% women) were included, the mean age at the time of wAIHA onset was 54 ± 23 years. wAIHA was considered "primary" for 21 patients (35%) and was associated with an underlying disorder in 39 (65%), including mainly lymphoproliferative disorders and systemic lupus. All patients but two needed treatment and received corticosteroids, with an overall initial response rate of 87%. However, 63% of the patients were corticosteroid-dependent and 56% required at least one second-line treatment including mainly rituximab (n = 19). At the time of analysis, after a mean follow-up of 46 months, 28 patients (47%) were in remission and off treatment and 5 (8%) had died. The presence of an underlying lymphoproliferative disorder was associated with reduced response to corticosteroids and increased need for second-line therapy. In conclusion, in the last decade and compared to a previous series from our center, the rate of secondary wAIHA has increased and the use of rituximab has emerged as the preferred second-line treatment and corticosteroid-sparing strategy; the overall mortality has significantly decreased (8 vs. 18%).

    2013-02-01

    Full Text Available Background: Conventional therapy against acute pediatric cardiopulmonary failure (APCPF caused by a variety of disease entities remains unsatisfactory with extremely high morbidity and mortality. For refractory APCPF, extracorporeal membrane oxygenation (ECMO is one of the last resorts. Methods: In this study, the in-hospital outcomes of pediatric patients with refractory APCPF receiving ECMO support were reviewed. Results: Between August 2006 and May 2011, a single-center cohort study was performed in pediatric patients who required ECMO support due to cardiogenic shock or severe hypoxemia. A total of 22 patients with mean age of 7.0 ± 6.3 years received ECMO (male = 11; female = 11. The indications included acute fulminant myocarditis (AFM (n = 6, congenital diaphragmatic hernia (CDH (n = 3, acute respiratory distress syndrome (ARDS (n = 6, enterovirus 71 (n = 3, viral sepsis (n = 2, refractory ventricular fibrillation due to long QT syndrome (n = 1, and pulmonary edema with brain herniation (n = 1. Eighteen patients received veno-arterial (VA mode ECMO, while another four patients undertook the veno-venous (VV mode. The duration of ECMO use and hospitalization were 6.1 ± 3.1 and 24.4 ± 19.4 days, respectively. The survival rate in patients with AFM was 100% (n = 6. Successful ECMO weaning with uneventful discharge from hospital was noted in 14 (63.6% patients, whereas in-hospital mortality despite successful ECMO weaning occurred in 5 patients (22.7%. Failure in ECMO weaning and in-hospital death was noted in 3 patients (13.6%. Conclusions: ECMO resuscitation is an effective strategy in the clinical setting of APCPF.

    Cardiac resynchronization therapy (CRT) implant procedures are often complex and prolonged, resulting in substantial ionizing radiation (IR) exposure to the patient and operator. We assessed the impact of lower-dose fluoroscopy settings and a sensor-based electromagnetic tracking system (MediGuide™, MDG) on reducing IR exposure during CRT implantation. A single-center 2-group cohort study was conducted on 348 consecutive patients, age 66.4 ± 11.0 years, 80.4% male, with CRT implant procedures from 2013 to 2015. Patients were arbitrarily assigned to MDG (N = 239) versus no MDG (N = 109) guidance. Lower-dose fluoroscopy settings were adopted in January 2015 (3 instead of 6 fps; 23 instead of 40 nGy/pulse; N = 101). Overall, MDG was associated with an 82.1% reduction in IR exposure (393 μGray·m(2) vs. 2191 μGray·m(2) , P dose fluoroscopy resulted in a 59.5% reduction in IR-exposure without MDG (1055 μGray·m(2) vs. 2608 μGray·m(2) , P Low-dose fluoroscopy combined with MDG was associated with a 95.9% lower exposure to IR when compared to standard fluoroscopy without MDG (108 μGray·m(2) vs. 2608 μGray·m(2) , P Low-dose fluoroscopy settings are highly effective (>50%) in reducing IR exposure during CRT implant procedures. When combined with MDG, >95% reduction in IR exposure is achieved. Moreover, MDG shortens procedural duration and may improve acute procedural outcomes. © 2016 Wiley Periodicals, Inc.

    2014-01-01

    Full Text Available Radiofrequency ablation (RFA is an effective minimally invasive treatment for nonsurgical hepatocellular carcinoma (HCC, but ablation of tumors close to the gallbladder could be associated with several complications. We report our experience on the treatment of HCC close to the gallbladder with RFA. Eight RFA procedures were performed in eight patients with HCC larger than 3 cm and less than 5 cm close to the gallbladder. In all cases, a percutaneous approach was used. There were no major complications. Only in two patients a minimal wall thickening of the gallbladder was observed. Contrast enhanced computed tomography carried out after 30 days from the first procedure showed complete necrosis in seven patients (87%. Only one patient had local recurrence at 11 months of followup. Although limited, our experience suggests that, after careful preprocedural planning, in experienced hands and with appropriate technology, percutaneous RFA could be safely performed even for lesions larger than 3 cm located in close adjacency to the gallbladder.

    This article summarizes our experiences in the application of continuous subcutaneous insulin infusion (CSII) as a method of rapid desensitization therapy for diabetic patients with insulin allergy that was subsequently switched to a regimen of multiple-dose injections for long-term insulin therapy. The clinical data of 11 diabetic patients with insulin allergy in Peking Union Medical College Hospital from April 1, 2008, through December 31, 2011, were retrospectively analyzed. All 11 conditions were diagnosed by case history, skin testing, determination of serum specific anti-insulin IgE, and reaction to withdrawal of insulin. Seven patients accepted the traditional injection method of desensitization, and 5 patients accepted CSII with the protocol designed for this study (1 patient accepted CSII after failure by the formal method). Six of the 7 patients who accepted the traditional method and all 5 patients who accepted CSII had successful results. All 5 patients in the CSII group switched to a regimen of multiple dosage injections. In a survey of 28 nurses, both experienced nurses and practical nurses preferred to use CSII as the method of desensitization. It is feasible and effective for diabetic patients with insulin allergy to use CSII as a method of rapid desensitization with subsequent switching to a regimen of multiple-dose injections for long-term insulin therapy.

    Using percutaneous nephrolitotomy (PCNL) with large adult instruments in treatment of pediatricurolithiasis is still in debate. This study was conducted to evaluate the efficacy and safety of PCNL with adult's instrument in treatment of patients less than 3 years old. Data on patient characteristics and outcomes for 261 consecutive children undergoing PCNL at a Labbafinejad University Hospital were collected prospectively from September 2006 to February 2016. Thirty-two children, with 34 renal units, who were treated with PCNL were enrolled in the study. All PCNL procedures were performed via subcostal approach with one access tract in all of them. Postoperative complications were evaluated according to the modified Clavien grading system. The mean age of patients was 19.4 ± 6.2 months. Two patients had bilateral stones; thus, PCNL was performed on 34 kidney units. The mean size of the largest stone diameter was 17.5 ± 7.8 mm. The mean duration of procedures was 121.52 ± 29.05 minutes, ranging from 60 to 180 minutes. The most common complication was fever (n = 9, 26.4%), and hemorrhage that needs transfusion was the second one (n = 4, 11.7%). Seventeen patients with complications were in the first degree of Clavien complication system and five of them were in the second degree. Due to our experience, utilizing PCNL with adult-sized instruments in management of urolithiasis in less than 3 years old children appeared to be effective and relatively safe.

    The introduction of flow diverter devices is revolutionizing the endovascular approach to cerebral aneurysms. Midterm and long-term results of angiographic, cross-sectional imaging and clinical follow-up are still lacking. The authors report their experience with endovascular treatment of intracranial aneurysms using both the Pipeline embolization device and Silk stents. From October 2008 to July 2011 a consecutive series of 104 intracranial aneurysms in 101 patients (79 female, 22 male; average age 53 years) were treated. Three of the 104 aneurysms were ruptured and 101 were unruptured. Silk stents were implanted in 47 of the aneurysms and Pipeline stents in the remaining 57. In 14 cases a combination of flow diverter devices and coils were used to treat larger aneurysms (maximum diameter > 15 mm). Patients underwent angiographic follow-up examination at 6 months after treatment, with or without CT or MRI, and at 1 year using CT or MRI, with or without conventional angiography. In all cases placement of flow diverter stents was technically successful. The mortality and morbidity rates were both 3%. Adverse events without lasting clinical sequelae occurred in 20% of cases. Angiography performed at 6 months after treatment showed complete aneurysm occlusion in 78 of 91 cases (86% of evaluated aneurysms) and subocclusion in 11 (12%); only in 2 cases were the aneurysms unchanged. Fifty-three aneurysms were evaluated at 1 year after treatment. None of these aneurysms showed recanalization, and 1 aneurysm, which was incompletely occluded at the 6-month follow-up examination, was finally occluded. Aneurysmal sac shrinkage was observed in 61% of assessable aneurysms. Parent artery reconstruction using flow diverter devices is a feasible, safe, and successful technique for the treatment of endovascular treatment of cerebral aneurysms.

    Purpose: To determine which parameters allow for CyberKnife fiducial-less tumor tracking in stereotactic body radiation therapy (SBRT) for early-stage non-small cell lung cancer. Methods and Materials: A total of 133 lung SBRT patients were preselected for direct soft-tissue tracking based on manufacturer recommendations (peripherally located tumors ≥1.5 cm with a dense appearance) and staff experience. Patients underwent a tumor visualization test to verify adequate detection by the tracking system (orthogonal radiographs). An analysis of potential predictors of successful tumor tracking was conducted looking at: tumor stage, size, histology, tumor projection on the vertebral column or mediastinum, distance to the diaphragm, lung-to-soft tissue ratio, and patient body mass index. Results: Tumor visualization was satisfactory for 88 patients (66%) and unsatisfactory for 45 patients (34%). Median time to treatment start was 6 days in the success group (range, 2-18 days) and 15 days (range, 3-63 days) in the failure group. A stage T2 (P=.04), larger tumor size (volume of 15.3 cm{sup 3} vs 6.5 cm{sup 3} in success and failure group, respectively) (P<.0001), and higher tumor density (0.86 g/cm{sup 3} vs 0.79 g/cm{sup 3}) were predictive of adequate detection. There was a 63% decrease in failure risk with every 1-cm increase in maximum tumor dimension (relative risk for failure = 0.37, CI=0.23-0.60, P=.001). A diameter of 3.6 cm predicted a success probability of 80%. Histology, lung-to-soft tissue ratio, distance to diaphragm, patient's body mass index, and tumor projection on vertebral column and mediastinum were not found to be predictive of success. Conclusions: Tumor size, volume, and density were the most predictive factors of a successful XSight Lung tumor tracking. Tumors >3.5 cm have ≥80% chance of being adequately visualized and therefore should all be considered for direct tumor tracking.

    OBJECT In patients with hydrocephalus and shunts, lasting symptoms such as headache and dizziness may be indicative of shunt failure, which may necessitate shunt revision. In cases of doubt, the authors monitor intracranial pressure (ICP) to determine the presence of over- or underdrainage of CSF to tailor management. In this study, the authors reviewed their experience of ICP monitoring in shunt failure. The aims of the study were to identify the complications and impact of ICP monitoring, as well as to determine the mean ICP and characteristics of the cardiac-induced ICP waves in pediatric versus adult over- and underdrainage. METHODS The study population included all pediatric and adult patients with hydrocephalus and shunts undergoing diagnostic ICP monitoring for tentative shunt failure during the 10-year period from 2002 to 2011. The patients were allocated into 3 groups depending on how they were managed following ICP monitoring: no drainage failure, overdrainage, or underdrainage. While patients with no drainage failure were managed conservatively without further actions, over- or underdrainage cases were managed with shunt revision or shunt valve adjustment. The ICP and ICP wave scores were determined from the continuous ICP waveforms. RESULTS The study population included 71 pediatric and 75 adult patients. There were no major complications related to ICP monitoring, but 1 patient was treated for a postoperative superficial wound infection and another experienced a minor bleed at the tip of the ICP sensor. Following ICP monitoring, shunt revision was performed in 74 (51%) of 146 patients, while valve adjustment was conducted in 17 (12%) and conservative measures without any actions in 55 (38%). Overdrainage was characterized by a higher percentage of episodes with negative mean ICP less than -5 to -10 mm Hg. The ICP wave scores, in particular the mean ICP wave amplitude (MWA), best differentiated underdrainage. Neither mean ICP nor MWA levels showed any

    AIM: To compare diagnostic sensitivity, specificity and accuracy of magnetic resonance cholangiopancreatography(MRCP) without contrast medium and endoscopic ultrasound(EUS)/endoscopic retrograde cholangiopancreatography(ERCP) for biliary calculi. METHODS: From January 2012 to December 2013, two-hundred-sixty-three patients underwent MRCP at our institution, all MRCP procedure were performed with the same machinery. In two-hundred MRCP was done for pure hepatobiliary symptoms and these patients are the subjects of this study. Among these two-hundred patients, one-hundred-eleven(55.5%) underwent ERCP after MRCP. The retrospective study design consisted in the systematic revision of all images from MRCP and EUS/ERCP performed by two radiologist with a long experience in biliary imaging, an experienced endoscopist and a senior consultant in Hepatobiliopancreatic surgery. A false positive was defined an MRCP showing calculi with no findings at EUS/ERCP; a true positive was defined as a concordance between MRCP and EUS/ERCP findings; a false negative was defined as the absence of images suggesting calculi at MRCP with calculi localization/extraction at EUS/ERCP and a true negative was defined as a patient with nocalculi at MRCP ad at least 6 mo of asymptomatic followup. Biliary tree dilatation was defined as a common bile duct diameter larger than 6 mm in a patient who had an in situ gallbladder. A third blinded radiologist who examined the MRCP and ERCP data reviewed misdiagnosed cases. Once obtained overall data on sensitivity, specificity, accuracy, positive predictive value(PPV) and negative predictive value(NPV) we divided patients in two groups composed of those having concordant MRCP and EUS/ERCP(Group A, 72 patients) and those having discordant MRCP and EUS/ERCP(Group B, 20 patients). Dataset comparisons had been made by the Student’s t-test and χ2 when appropriate.RESULTS: Two-hundred patients(91 men, 109 women, mean age 67.6 years, and range 25-98 years

    Full Text Available Transplant nephrectomy (TN is associated with significant morbidity and mortality and influences the outcome of subsequent renal transplantation. The aim of this study was to identify the reasons for TN in a single transplant center in the United Kingdom and to determine the complication rate, effect on relisting and re-transplantation. We studied all the TNs in our center from January 2000 to December 2011. Detailed information including cause of allograft failure and reason for TN were analyzed. Of 602 renal transplants performed at our center during the period of the study, 42 TNs were performed on 38 (6% patients (24 men and 14 women. The median age of the patients at the time of transplantation who subsequently underwent TN was 56 years (range: 28-73 years and 71% of the allografts were donated after circulatory death. The mean human leucocyte antigen mismatch for these patients was 2.3. The most commonly used immunosuppression was a combination of prednisolone, mycophenolate and tacrolimus, which was used in 50% of the patients. Twenty-five (60% of the TNs in this series were for allografts failing during the first month of transplantation. The most common indication for the TN was graft thrombosis (50%, with an overall in-hospital mortality rate of 9.5% and a morbidity rate of 31%. Seven of 19 patients listed underwent successful re-transplantation. Although TN is associated with a risk of significant morbidity and mortality, it does not preclude from listing for re-transplantation. The difficulty of access to complete information about transplant failures and TN highlights the need for a national registry.

    Results: Twenty-nine patients were diagnosed with Candida infection. Of these patients 17 were male (59% and 12 were female (41%. Eleven patients were less than a year old (38%, 9 were between 1-5 years (31% and 9 were above the age of five (31%. The most important underlying disease malignancies were congenital heart disease and neurological diseases. Candida growth was determined in the blood cultures of 17 patients, the urine cultures of 10 patients and in the cerebrospinal fluid of one patient. While the most commonly used anti-fungal agent was fluconazole (51.7%, others used were caspofungin (41.3% and amfoterisin B (13.7%. No isolated Candida strain showed resistance to anti-fungal agents. Treatment was clinically and microbiologically 96.5% successful. Conclusions: Fluconazole still appears to be an effective treatment choice we believe there is a necessity to review the Minimal Inhibitory Concentration (MIC values for anti-fungal agents.

    Full Text Available Aim: To evaluate the demographic and clinical parameters affecting the outcomes of ambulatory laparoscopic cholecystectomy (ALC in terms of pain, nausea, anxiety level, and satisfaction of patients in a tertiary health center. Materials and Methods: ALC was offered to 60 patients who met the inclusion criteria. Follow-up (questioning for postoperative pain or discomfort, nausea or vomiting, overall satisfaction was done by telephone contact on the same day at 22:00 p.m. and the first day after surgery at 8: 00 a.m. and by clinical examination one week after operation. STAI I and II data were used for proceeding to the level of anxiety of patients before and/or after the operation. Results: Sixty consecutive patients, with a mean age of 40.6 ± 8.1 years underwent ALC. Fifty-five (92% patients could be sent to their homes on the same day but five patients could not be sent due to anxiety, pain, or social indications. Nausea was reported in four (6.7% cases and not associated with any demographic or clinical features of patients. On the other hand, pain has been reported in 28 (46.7% cases, and obesity and shorter duration of gallbladder disease were associated with the increased pain perception (P = 0.009 and 0.004, respectively. Preopereative anxiety level was significantly higher among patients who could not complete the ALC procedure (P = 0.018. Conclusion: Correct management of these possible adverse effects results in the increased satisfaction of patients and may encourage this more cost-effective and safe method of laparoscopic cholecystectomy.

    Transplant tourism is the term used for patients who travel abroad for transplantation. Transplant tourism has always been surrounded with controversy regarding how these organs were obtained, the donor's care after transplantation, and the recipient outcome. Many authors have found that the outcome of the recipients in transplant tourism is inferior to those transplanted in their own countries. However, most these studies were small, with the latest one including only 33 patients. Here, we describe the outcome of 93 patients who were transplanted abroad compared with local transplantation. All transplant patients who were followed up at our Nephrology Clinic from 1998 until 2008 were identified using our data base system. We selected patients transplanted from 2003 and forward because the computerized system for laboratory and electronic records began operation that year. A total of 165 patients were identified (93 in the tourist group and 72 in the local one). Transplant tourists had a higher rate of acute rejection in the first year compared with local transplantation (27.9% vs. 9.9, P=0.005), higher mean creatinine at 6 months and 1 year (120 vs. 101 micromol/L, P=0.0007, 113 vs. 98 micromol/L, P=0.008). There was no statistical difference in graft or patient survival in 1 or 2 years after transplantation. However, transplant tourist had a higher rate of cytomegalovirus infection (15.1% vs. 5.6%, P=0.05) and hepatitis C seroconversion (7.5% vs. 0%, P=0.02). Transplant tourists had a more complex posttransplantation course with higher incidence of acute rejection and infectious complications.

    Full Text Available Successful pregnancy outcome is an uncommon occurrence in women requiring chronic dialysis treatment. We reviewed the course and outcome of 9 pregnancies occurred in women on chronic hemodialysis in our center from 1999-2007; 5 of them ended with delivery of alive newborns, 2 with fetal deaths in-utero, and 2 with abortions. The average age of patients was 34 years. The etiology of the original kidney disease was unknown in 44.4% of the cases, and only 22.2% of the patients maintained diuresis. Dialysis started in 8 cases before the diagnosis of pregnancy. The average gestational age at diagnosis was 14 weeks. We modified the prescription of dialysis in 4 patients by increasing the frequency of the dialysis sessions to 6 per week and in 3 by increasing the duration of each session to 6 hours. Anemia was present in all the cases; 3 patients received erythropoietin and 4 patients required transfusion. The pregnancy was com-plicated in 44% of the cases by a polyhydramnios. The average time at delivery was 33 weeks and it was achieved in 80% of pregnancies through vaginal route. The average weight of newborns was to 2380 g. We conclude that pregnancy in women on hemodialysis is possible. The success of pregnancy may be influenced by the residual diuresis and early diagnosis to improve the quality of dialysis by increasing the dialysis dose.

    Objective To explore the treatment, procedure related risks, and outcomes of patients older than 90 years of age undergoing cardiac catheterization. Methods We retrospectively studied 32 patients ≥ 90 years (93.0 ± 1.2 years) who underwent cardiac catheterisation in a tertiary specialist hospital (0.2% of 14,892 procedures during three years). The results were compared to a patient cohort younger than 90 years of age. Results Baseline characteristics revealed a higher prevalence of diabetes (P < 0.001), chronic obstructive pulmonary disease (P < 0.04), previous myocardial infarction (P < 0.02), and complex coronary anatomy (SYNTAX score 33 vs. 19) in nonagenarians. Patients < 90 years of age showed more hyperlipidemia (P < 0.01) and previous percutaneous coronary interventions (P < 0.015). Nonagenarians underwent coronary angiography more often for acute coronary syndrome (ACS) (P < 0.003), were presented more often in cardiogenic shock (P < 0.003), and were transferred faster to coronary angiography in cases of ACS (P < 0.0001). The observed in-hospital mortality rate (13% study group vs. 1% control group; P < 0.003) in nonagenarians was lower than the calculated rate of thrombolysis in myocardial infarction (TIMI) and global registry of acute cardiac events (GRACE) mortality and strongly influenced by the severity of clinical presentation and the presence of co-morbidities. Conclusion Despite the common scepticism that cardiac catheterisation exposes patients ≥ 90 years to an unwarranted risk, our data demonstrate an acceptable incidence of complications and mortality in this group of patients.

    Full Text Available Typhoid fever is endemic in many developing countries with a high rate of complications. Aim of this study is to analyse epidemiological features, clinical presentations, complications and therapeutic outcomes of enteric perforation peritonitis diagnosed and treated in our hospital. Records of total number of 646 patients, who presented with perforation peritonitis due to enteric fever in the surgical emergency unit of Dr Ram Manohar Lohia hospital, New Delhi between January 2001 and December 2013, were reviewed retrospectively. Descriptive statistics was used to analyze the data. Out of 646 patients, 62 (9.59% presented in shock. Stomal, peristomal, local and systemic complications were high in these patients. Primary closure was done in 212 (33.12 patients, primary ileostomy was created in 410 (64.06 patients, and resection and anastomosis was done in 24 (3.75 patients. Thirteen patients (2.01% died of typhoid intestinal perforation. To prevent complications of typhoid fever, in addition to control sanitation, it is also important to control quackery and malpractices. Awareness and education about the disease, its nature and complications will also be of great help.

    In non-valvular atrial fibrillation 90% of thrombi originate in the left atrial appendage (LAA). Percutaneous LAA closure has been shown to be non-inferior to warfarin for prevention of thromboembolism. To evaluate the initial experience of a single center in percutaneous LAA closure in patients with high thromboembolic risk and in whom oral anticoagulation was impractical or contraindicated or had failed. Patients with non-valvular atrial fibrillation and CHADS2 score ≥2 in whom oral anticoagulation was impractical or contraindicated or had failed underwent percutaneous LAA closure according to the standard technique. After the procedure, dual antiplatelet therapy was maintained for one month, followed by single antiplatelet therapy indefinitely. Patients were followed by clinical assessment and transthoracic and transesophageal echocardiography. The procedure was performed in 22 of the 23 selected patients (95.7%), mean age 70±9 years, CHADS2 score 3.2±0.9 and CHA2DS2-VASC score 4.7±1.4. Intraprocedural device replacement was necessary only in the first patient, due to oversizing. The following periprocedural complications were observed: one femoral pseudoaneurysm, three femoral hematomas and two minor oropharyngeal bleeds, resolved by local hemostatic measures. During a 12±8 month follow-up a mild peri-device flow and a thrombus adhering to the device, resolved under with enoxaparin therapy, were identified. The rate of transient ischemic attack (TIA)/stroke was lower than expected according to the CHADS2 score (0 vs. 6.7±2.2%). In our initial experience, this procedure proved to be a feasible, safe and effective alternative for atrial fibrillation patients in whom oral anticoagulation is not an option. Only relatively minor complications were observed, with a lower than expected TIA/stroke rate. Copyright © 2012 Sociedade Portuguesa de Cardiologia. Published by Elsevier España.

    Purpose: The Genous™ stent (GS) is designed to accelerate endothelization, which is potentially useful in the pro-thrombotic environment of ST-elevation acute myocardial infarction (STEMI). We aimed to evaluate the safety and effectiveness of the GS in the first year following primary percutaneous coronary intervention (PCI) and to compare our results with the few previously published studies. Methods and Materials: All patients admitted to a single center due to STEMI that underwent primary PCI using exclusively GS, between May 2006 and January 2012, were enrolled. The primary study endpoints were major adverse cardiac events (MACEs), defined as the composite of cardiac death, acute myocardial infarction and target vessel revascularization, at one and 12 months. Results: In the cohort of 109 patients (73.4% male, 59 ± 12 years), 24.8% were diabetic. PCI was performed in 116 lesions with angiographic success in 99.1%, using 148 GS with median diameter of 3.00 mm (2.50–4.00) and median length of 15 mm (9–33). Cumulative MACEs were 2.8% at one month and 6.4% at 12 months. Three stent thromboses (2.8%), all subacute, and one stent restenosis (0.9%) occurred. These accounted for the four target vessel revascularizations (3.7%). At 12 months, 33.9% of patients were not on dual antiplatelet therapy. Conclusions: GS was safe and effective in the first year following primary PCI in STEMI, with an apparently safer profile comparing with the previously published data. Summary: We report the safety and effectiveness of the Genous™ stent (GS) in the first year following primary percutaneous coronary intervention in ST-elevation acute myocardial infarction. A comprehensive review of the few studies that have been published on this subject was included and some suggest a less safe profile of the GS. Our results and the critical review included may add information and reinforce the safety and effectiveness of the GS in ST-elevation in acute myocardial infarction.

    Full Text Available Objective: Fecal diversion is often indicated in cases with fecal incontinence, Fournier’s gangrene, anal fistula, and inoperable obstructive anorectal cancer. Trephine colostomy can be performed without necessitating laparotomy. We present our experience related to the outcome of trephine sigmoid colostomy. Methods: The retrospective study included 14 patients who underwent trephine colostomy due to various conditions including Fournier’s gangrene, inoperable anorectal cancer, recto-vaginal fistula, and benign stricture due to radiotherapy at our clinic between January 2010 and January 2015. Results: Patients comprised 4 females and 10 males with a mean age of 52.07 years. The indications for stoma formation were Fournier’s gangrene in 7 cases, inoperable anorectal cancer in 5, rectovaginal fistula in 1, and benign stricture due to radiotherapy in 1 case. Eight patients underwent surgery under regional anesthesia. All the patients underwent trephine loop sigmoid colostomy. One patient had second operation on the postoperative period due to colostomy prolapse. The temporary stomas were closed in 3 months. Mean length of hospital stay was 14 days. Conclusion: Trephine stoma is a relatively simple, safe and rapid procedure and an effective alternative to colostomy formation without laparotomy indications. It can be performed under emergency or elective conditions with low morbidity. J Clin Exp Invest 2015; 6 (2: 87-90

    Full Text Available We present our experience of 22 cases of emphysematous pyelonephritis (EPN treated from 1996 to 2012. Medical records were analyzed retrospectively for demographic profile, presence and duration of diabetes mellitus, and mode of clinical presentation. EPN was diagnosed based on demonstration of intra-renal gas by plain X-ray, ultrasound, and/or computed tomography (CT scan. Details of medical treatment, reason for surgical intervention, and final outcome were recorded. Univariate analysis was performed to identify risk factors for mortality and P value of less than 0.05 was taken as significant. Twenty-two cases (6 males, 16 females of EPN were diagnosed. Seven cases presented with acute pyelonephritis, seven cases with urosepsis, and the remaining eight patients with multi-organ dysfunction. CT grading of EPN was class IV in three, class III in four, class II in 14, and class I in one. All were initially managed medically with parenteral antibiotics. Ten patients needed additional surgical intervention. The overall survival rate was 86.3% (19/22. Among the risk factors analyzed higher CT grade, altered sensorium and thrombocytopenia were significantly associated with mortality. We conclude that a more conservative approach in managing EPN has become the standard of care. Patients having high CT grade of lesions (III and IV with altered sensorium and thrombocytopenia at presentation are more likely to die due to the disease and may be better managed by an aggressive surgical plan.

    Full Text Available Introduction: Immunocompromised patients carry a high risk for invasive fungal disease (IFD, which is associated with high mortality. Materials and Methods: This is a retrospective chart review of a 4 years’ experience of ABLC utilization for the management of suspected IFD at the Hematology/Oncology and Bone Marrow Transplantation unit at Makassed General Hospital, Beirut, Lebanon between January 2011 and December 2014. We focused on treatment strategy, response rate and adverse drug events associated with ABLC therapy. We also reviewed ABLC indications in international guidelines beyond its Food and Drug Administration approval. Results: A total of 89 patients received ABLC therapy for suspected fungal infection. Forty eight percent (48% were treated for a possible fungal infection, 19% for a problable fungal infection, 12% based on hospital guidelines, and 20% based on treating physician’s recommendations. The overall response rate was 71%. Nephrotoxicity occurred in 24% of patients and serum creatinine improved in 10% of these patients. Moderate hypokalemia was observed in 61% of the patients and severe hypokalemia in 10% but was corrected in both cases. Hepatotoxicity was observed in 12% of the patients throughout ABLC therapy. Drug delivery reactions were observed in 36% of the patients. There was a decrease in the incidence of these reactions upon using combination of premedication drugs. Conclusion: In this study, ABLC proved to be an effective and safe option in the management of suspected IFD in immunocompromised patients failing previous therapies.

    BACKGROUND:Perioperative treatment of emergency liver transplantation for acute hepatic failure is extremely different from common liver transplantation, due to complex conditions, high risk, several complications, and high mortality. OBJECTIVE:To summarize the experience of emergency liver transplantation for acute hepatic failure during the perioperative period, and to increase the success rate in treatment of acute hepatic failure. METHODS:A retrospective analysis was undertaken on the clinical data of 38 cases undergone emergency liver transplantation for acute hepatic failure. There were 21 male and 17 female, who aged 15-69 years. Among them, 23 cases had hepatitis B virus (including 2 cases with hepatitis B and C virus), 7 cases had Wilsons disease, 3 cases had mushroom poisoning, 2 cases had unknown liver damage, 1 case had Tripterygium wilfordi poisoning, 1 case had decompensation after partial liver resection due to trauma, and 1 case had liver transplantation from corpse. RESULTS AND CONCLUSION:The survival time of the involve patients was 13-1 740 days, and the median survival time was 634 days. Perioperative survival rate was 76%, 1-year survival rate was 63%, and 2-year survival rate was 58%. During the perioperation nine cases died of brain edema and intracranial hypertension, renal failure, severe pulmonary infection, multiple organ failure, coagulation disorders (intracranial hemorrhage, upper digestive tract hemorrhage), acute respiratory distress syndrome and primary graft non-function. At present, emergency liver transplantation is stil the most effective way for acute liver failure. Hemorrhage, infection and rejection are the leading causes of the death. Each perioperative treatment is of great significance for the success of liver transplantation and long-term survival.%背景:急性肝衰竭行急诊肝移植患者围手术期治疗的病情复杂,风险大,并发症多,死亡率高,与普通肝脏移植有着明显不同。目的

    Objective To investigate the experience of renal transplantation of donation after cardiac death and clinical effect of immune-induced therapy. Methods We retrospectively analyzed 40 renal transplantation of donation after cardiac death in our hospital from Dec 2011 to Dec 2013 . According to the different immune-inducing drugs,the recipients were divided into three groups:basiliximab group(10 cases),ATG group (15 ca-ses)and ATG-F group (15 cases). Results Among 40 patients,the serum creatinines were steadily decreased in the postoperative period except 3 cases. One case of DGF appeared in each group. One case of acute rejection appeared in ATG group and the rest had no acute rejection occurred,the primary non-functioning kidney was not occurred in the three group. The incidence of CMV infections were 40%,71%and 73% respectively. Pneu-monia occurred 1 case in ATG group,the rest of the groups had no pneumonia. The decline of platelets and he-moglobin were observed in 5 and 6 cases in ATG group and ATG-F group,no other adverse effects were ob-served. Except one case of pneumonia died in ATG group,the rest were all alive with functional kidney. The clear structures of glomerular and tubular were observed in no-DGF kidney,while the swelling renal tubular and some necrosis tubular appeared in DGF kidney. Conclusions DCD is an important means to solve the short-age of organ. DBCD is an ideal DCD donor. Induced immunity can be effective in preventing the occurrence of acute rejection,but it can cause the widespread suppression,which can lead to the latent resurrection of CMV, the warm ischemia time should be as short as possible,which can cause a low incidence of DGF. Renal biopsy should be done for a routine examination in DCD,but the decision of choose should be carefully done.%目的:探讨DCD捐献肾脏移植的经验及免疫诱导的临床效果观察。方法分析本院于2011年12月至2013年12月完成的40例DCD捐献肾移植患者的临床资料,根据

    Quiver quantum mechanics is invariant under Seiberg duality. A mathematical consequence is that the cohomology of the Higgs branch moduli space is invariant under mutations of the quiver. The Coulomb branch formula, on the other hand, conjecturally expresses the Poincaré/Dolbeault polynomial of the Higgs branch moduli space in terms of certain quantities known as single-centered indices. In this work we determine the transformations of these single-centered indices under mutations. Moreover, we generalize these mutations to quivers whose nodes carry single-centered indices different from unity. Although the Higgs branch description of these generalized quivers is currently unknown, the Coulomb branch formula is conjectured to be invariant under generalized mutations.

    The use of minimally invasive surgery for the treatment of lung cancer has been growing worldwide. Between May 2008 and November 2012, we performed 24 videothoracoscopic anatomical lung resections in our department. This includes 22 lobectomies and 2 anatomic segmentectomies, which is known to be a more complex surgery, since it demands a finer dissection of sub-lobar structures. We report the clinical cases of two patients who underwent anatomic segmentectomies. The first one was a 63 year old woman, smoker and with a history of breast cancer 20 years earlier. An incidental 9 mm node was found in the lingula. The patient underwent an anatomic lingulectomy and the frozen section was suggestive of a primary lung cancer. Therefore, we proceeded to a full lymphadenectomy. The final pathology evaluation showed a typical carcinoid tumour (pT1aN0). The second patient was a 50 year old woman, a smoker and with a heavy family history of lung cancer. In a screening CT scan a 8 mm ground glass opacity was identified in the left lower lobe (segment VI). After a VATS wedge resection of the node the frozen section evaluation was compatible with adenocarcinoma. We then proceeded to an anatomic segmentectomy with lymphadenectomy. The definitive pathology evaluation confirmed that it was a pT1a N0 bronchioloalveolar adenocarcinoma. The patients now have 5 and 2 months of follow up respectivelly and neither of them has signs of recurrence and the surgical incision showed a good aesthetic result. Anatomic segmentectomy is the indicated surgery especially in patients with low grade tumours, in early stage lung cancers or in patients without pulmonary function for a lobar resection, and it can be done safely using VATS.

    Though frequently observed in children, intussusception is a rare state in adults. The treatment of intussusception in adults is different. In this trial, we have presented intussusception cases in adults that were treated and followed up in our department. The records of 31 adult intussusception cases surgically treated in our department between January 1993 and July 2012 were evaluated retrospectively. Among the 31 adult cases of intussusception that were treated during a period of 19 years, 10 were men, and 21 were women. The mean age was determined as 39.7 ± 5.3. The presentation symptom was abdominal pain in all the patients. Failure to pass gas or feces was observed in 23 patients (74.2 %); nausea and vomiting, in 22 patients (70.9 %); hematochezia, in 16 patients (51.6 %); and weight loss, in 3 patients (9.6 %). The mean duration of symptoms was 4.8 days. Abdominal tenderness was found in all the patients. Muscular defense and rebound tenderness were determined in 13 patients (41.9 %). Findings of intussusception were found in 80.9 % of patients examined by abdominal ultrasonography and in 63.1 % of cases examined by computerized tomography. Resection of the intussuscepted bowel segment was performed in 87 % of the patients. In conclusion, intussusception in adults is a rare clinical entity. Intussusception should be considered in the differential diagnosis in patients presenting with spasmodic abdominal pain, especially in cases with intestinal obstruction. The recommended surgical method is en bloc resection of the intussuscepted segment in cases suspected to carry a risk of malignancy.

    The coexistence of psoriasis with systemic lupus erythematosus (SLE) has been reported in limited case series, raising hypotheses about shared pathogenetic mechanisms. Nevertheless, important differences regarding treatment do exist. The aim of the present study was to determine the prevalence and characteristics of psoriasis in a defined cohort of lupus patients. Patients with psoriasis were retrieved from the University of Toronto Lupus Clinic from its inception in 1970 up to 2015. Charts were hand-searched to collect information concerning demographic, clinical, and therapeutic variables. Patients were matched with non-psoriasis lupus patients to identify the impact of supervening psoriasis on lupus activity, damage accrual, and venous thromboembolic (VTEs) and cardiovascular events (CVEs). Psoriasis was diagnosed in 63 patients (49 females, 14 males) for a prevalence of 3.46% (63/1823). The male-to-female ratio was significantly higher in non-psoriasis patients (0.286 vs. 0.138, p = 0.017). Plaque psoriasis was the most prominent type (55/63, 87.3%) whereas three patients had pustular disease; one had psoriatic arthritis. Nine patients (14.3%) were administered systemic treatment with methotrexate (n = 5), azathioprine (n = 1), ustekinumab (n = 3), and etanercept (n = 1). Psoriasis was definitely deteriorated by hydroxychloroquine in one patient. There was no significant impact of psoriasis on disease activity, damage accrual, VTEs, and CVEs. The prevalence of psoriasis was twice as high as that of the general Canadian population in this lupus cohort. Plaque psoriasis was the most prominent subtype, and topical treatment was adequate in the majority of patients. Supervening psoriasis had no significant impact on lupus activity and damage accrual.

    Full Text Available Objectives: The objective was to highlight the frequency, clinical profile, and predisposing factors of ectopic pregnancy (EP in a general hospital. Materials and Methods: This descriptive study was conducted at the Obstetrics and Gynaecology department of Hera General hospital, Makkah, Saudi Arabia, from July 1, 2009 to December 29, 2010. Data were collected on chief medical complaints, sociodemographic characteristics, past obstetrics and gynecological history, management done, and outcome of management. Data were analyzed using Microsoft Office Excel (version 2007. Results: Out of total 7564 pregnancies, 44 (0.58% patients were diagnosed as EP. Out of 44, 22 (50% patients presented within 24 h of onset of symptoms. Mean age was 28 ± 7 years. Multigravida were predominant in 25 (57%, and 21 (48% had gestational age of 6-8 weeks at the time of presentation; the common presenting features were amenorrhea (41, 93.2%, abdominal pain (39, 88.6%, and tenderness (38, 86%. Previous pelvic surgery (13, 29.5%, infertility treatment (11, 25%, and pelvic inflammatory disease (10, 22.7% were the common predisposing factors. Twenty-five (57% presented with ruptured EP and were operated within 24 h, and the remaining were kept under observation till further diagnosis. After confirming the diagnosis, 12/19 underwent laparoscopy, whereas 7/19 received medical treatment. Surgery confirmed fallopian tube pregnancies in 35 (94.5%. No mortality was observed. Conclusion: Previous pelvic surgeries were the major etiological factor for EP. Other factors were infertility treatment and pelvic inflammatory disease. The most common site of EP was fallopian tubes.

    Full Text Available Objective: In the present study, determination of symptoms, clinical characteristics, prevalence and recovery rates was aimed in patients who applied to the emergency service and diagnosed with hypernatremia. Methods: Patients who applied to Dicle University Medical School Emergency Service during January 2013-December 2014 and whose serum Na>148 mEq/L were included in the study. The study was conducted retrospectively. Results: Hypernatremia prevalence was determined as 0.21% in the cases who applied to the emergency service. The average age in all patients was 69±22 and the median age was 72 years. The average hospitalization period was 13.3±10.9 days. The mortality rate was 75.7% and male gender domination (56% was determined in patients who developed mortality. When mortality and recovery groups were compared statistically; significant difference was determined (p<0.05 in terms of hospitalization period, glucose, urea, creatinine and calcium averages. The complaints of our patients who applied to the emergency service were changes in consciousness (92.7%, oral intake disorder (83.4% and fever (48.6% based on frequency order. The accompanying comorbid states were cerebrovascular illness (36.9%, Dementia/Alzheimer (32.4% and hypertension (28.9% based on frequency order. Conclusion: Consequently, hypernatremia is a fluid-electrolyte disorder progressing with high mortality and could be observed in older patients and in patients whose oral intake is defective and who have cerebrovascular illness and dementia.

    Full Text Available Methanol is a cheap and potent adulterant of illicit liquors. Hemodialysis (HD is the best method to rapidly remove both toxic acid metabolites and parent alcohols, and it plays a fundamental role in treating severely poisoned patients. This retrospective study was carried out on 91 patients with detectable serum methanol levels who underwent HD. Because toxic alcohol levels were not immediately available, the initial diagnosis and treatment was based on clinical history with evidence of toxic alcohol intake, presence of high anion metabolic acidosis and/or end organ damage. Patients received bicarbonate, ethanol, according to clinical features and blood gases. Patients underwent HD in the setting of known methanol ingestion with high anion gap metabolic acidosis, or evidence of end-organ damage, regardless of methanol level. HD prescription included large surface area dialyzer (≥1.5 m2, blood flow rate of 250-350 mL/min and dialysate flow rate of 500 mL/min for 4-6 h. Between 9 and 11 July 2009, 91 males with mean age 40 ± 8.5 years underwent HD, and 13 patients required a second HD session. Patients consumed 100-500 mL illicit liquors, and symptoms appeared six and 60 h later. Clinical features were gastro-intestinal symptoms (83.5%, visual disturbances (60.4%, central nervous system symptoms (59.3% and dyspnea (43.9%. Before HD, mean pH was 7.11 ± 0.04 (range 6.70- 7.33 and mean bicarbonate levels were 8.5 ± 4.9 mmol/L (range 2-18. Three patients died due to methanol intoxication. Mortality was associated with severe metabolic acidosis (pH ≤ 6.90, ventilator requirement and coma/seizure on admission (P < 0.001. Timely HD, bicarbonate, ethanol and supportive therapy can be life-saving in methanol intoxication.

    L’autotrapianto d’isole pancreatiche (IAT) è una procedura ben nota che consente di migliorare il controllo glicemico dopo una pancreasectomia totale (o completamento di pancreasectomia dopo duodenocefalopancreasectomia) rispetto alla sola terapia insulinica. In questo lavoro presentiamo la nostra esperienza nel campo dell’ IAT riportando il caso clinico di una donna di sessanta anni, sottoposta a completamento di pancreasectomia per episodi ricorrenti di acuzie in un quadro di pancreatite cronica. Il trattamento IAT è stato somministrato mediante iniezione trans-epatica intra-portale. Il recupero post-procedurale è stato ottimale, fatta eccezione per un’infezione di ferita che ha richiesto un trattamento con tecnologia a pressione negativa. La paziente è stata dimessa in ventisettesima giornata postoperatoria, in buone condizioni generali, dopo regolare ripresa dell’alimentazione e della canalizzazione. I dati presenti in letteratura dimostrano che la IAT è una procedura sicura, garantendo nel lungo periodo un vantaggio rispetto alla terapia insulinica in termini di rapporto costo-beneficio. Riguardo alla procedura chirurgica, è qui utile ricordare che la mortalità a 30 giorni dopo pancreasectomia totale associata a IAT è del 5%, ed è pertanto sovrapponibile ai risultati della pancreasectomia totale senza IAT. Riportando questa esperienza intendiamo contribuire alla crescita della casistica chirurgica attuale in questo campo, proponendo nel futuro un più ampio sviluppo e una più estesa applicazione di tale approccio.

    The aim of this study was to identify potential risk factors linked to neurologic events (NE) occurring after liver transplantation (LT) and use them to construct a model to predict such events. From odds ratios (OR) of risk factors, a scoring system was assessed using multivariate regression analysis. Forty-one of 307 LT patients presented NE (13.3%), with prolonged hospital stay and decreased post-LT survival. On multivariate analysis, factors associated with NE included: severe pre-LT ascites OR 3.9 (1.80-8.41; P = 0.001), delta sodium ≥12 mEq/l OR 3.5 (1.36-8.67; P = 0.01), and post-LT hypomagnesemia OR 2.9 (1.37-5.98; P = 0.005). Points were assigned depending on ORs as follows: ascites 4 points, and hypomagnesemia and delta sodium ≥12 mEq/l, 3 points each (score range = 0-10 points). ROC curve analysis suggested good discriminative power for the model, with a c-statistic of 0.72 (CI 0.62-0.81; P 3 points (71% sensitivity, 60% specificity). NE risk increased progressively from 6.4%, to 10.3%, 12.8%, 31.5% and 71.0% as scores rose from 0 to 3, 4, 6-7 and 10 cumulative points, respectively. The score described helps to identify patients potentially at risk for neurologic events, and its prevention would decrease morbidity and mortality after LT.

    Conclusion: Multiple aneurysms, poor grade and intracerebral hematomas are poor prognostic factors. The patients who have subarachnoid hemorrhage should be monitored by an experienced team of neurosurgery and intensive care and should be operated on as soon as possible because of rehemorrhage risk. The surgical clipping as a gold standard is still an affective and successful method. [Cukurova Med J 2016; 41(4.000: 732-743

    Full Text Available  Introduction: Transcatheter closure is a treatment choice for the most children with patent ductus arteriosus (PDA. The closure of the ductus is indicated in any child or adolescent with developed symptoms of significant L-R shunt. The aim of this article is to present our results in 5 years treatment of patients with PDA and their outcome. Methods: From 2009 to 2014, 30 patients underwent a transcatheter closure of PDA at Centre for Heart and Pediatric clinic of Clinical University Centre of Sarajevo. Aortic angiogram was performed to evaluate the size, position, and shape of the duct for selection of appropriate occluder device type and size. All procedures were performed by local team of cardiologists from the Department of Cardiology, Pediatric clinic, with invasive cardiologists team from Sweden and Austria. Echocardiography was repeated at intervals of 24 hours, then 1month, 3 months, and 1 year after the procedure to assess the outcome. Results: Thirty patients underwent transcatheter closure of PDA during the study period. PDA of ≤ 2.0 mm was present in 8 patients and they underwent PDA closure with coils, while 22 patients had PDA diameter  ≥ 2 mm, and they were treated by Amplatzer duct occluder (ADO. Only in 2 (6.2% patients complications have been observed. The length of hospital stay after the treatment was two to three days. Conclusion: Transcatheter closure of PDA is a modern, safe and efficient method that ensures a faster recovery of the patients, shortens the length of hospitalization.

    PurposeThe AngioVac catheter system is a mechanical suction device designed for removal of intravascular material using extracorporeal veno-venous bypass circuit. The purpose of this study is to present the outcomes in patients treated with the AngioVac aspiration system and to discuss its efficacy in different vascular beds.Materials and MethodsA retrospectively review was performed of seven patients treated with AngioVac between October 2013 and December 2014. In 6/7 cases, the AngioVac cannula was inserted percutaneously and the patient was placed on veno-venous bypass. In one of the cases, the cannula was inserted directly into the Fontan circuit after sternotomy and the patient was maintained on cardiopulmonary bypass. Thrombus location included iliocaval (2), SVC (1), pulmonary arteries (1), Fontan circuit and Glenn shunt with pulmonary artery extension (1), right atrium (1), and IVC with renal vein extension (1).ResultsThe majority of thrombus (50–95 %) was removed in 5/7 cases, and partial thrombus removal (<50 %) was confirmed in 2/7 cases. Mean follow-up was 205 days (range 64–403 days). All patients were alive at latest follow-up. Minor complications included three neck hematomas in two total patients. No major complications occurred.ConclusionAngioVac is a useful tool for acute thrombus removal in the large vessels. The setup and substantial cost may limit its application in straightforward cases. More studies are needed to establish the utility of AngioVac in treatment of intravascular and intracardiac material.

    Full Text Available OBJECTIVE: End-stage kidney disease and advanced cirrhosis are sometimes seen concomitantly. Our purpose was to compare hemodialysis (HD sessions in critically ill cirrhotic patients from ICU versus stable cirrhotic patients from outpatient clinic, and observe endurance of both stable and acutely ill cirrhotic patients to intermittent HD. MATERIAL and METHODS: All of the Child-Pugh class B or C cirrhotic patients requiring renal replacement therapy during a period of three years were included in the study. If hypotension, arrhythmia, bleeding, or any other health problems were present during dialysis, the dialysis session was regarded as a troubled session. RESULTS: There were two groups of patients. All of the stable patients lived more than three months, whereas all patients in the ICU group died within a month. Mean ultrafiltration volume per session was 1786±210 ml in ICU and 1616±266 ml in stable patients (p>0.05. The number of the troubled sessions was 24 in ICU and 1 in stable patients (p<0.0001. Bleeding was a problem in a minority of the patients. CONCLUSION: Intermittent HD may be an acceptable choice for stable cirrhotic dialysis patients. Hypotension is a frequent complication of intermittent HD in ICU patients.

    Full Text Available Aims and Objective. “Postpercutaneous nephrolithotomy nephrostogram” (PPNN is routinely performed in most of the centers. No published series could be found in the literature without post percutaneous nephrolithotomy nephrostogram. Hence, the aim of our study is to highlight that post percutaneous nephrolithotomy nephrostogram is not mandatory and it only adds to cost and morbidity without adding any information in the management of such patients. Methods. It was a prospective study from 2005 to 2012, conducted in our institute. It included 119 patients of renal stones who underwent percutaneous nephrolithotomy performed under the guidance of a single surgeon. Postoperative nephrostogram was not done in any of the patients. Results. Complete stone clearance was achieved in 97.5% of patients and 2.5% of patients needed two to three sessions of ESWL later on. None of the patients needed second look percutaneous nephrolithotomy or nephrostogram. Conclusion. Postpercutaneous nephrolithotomy nephrostogram increases chances of infection, inconvenience, contrast related complications, and cost, with no added advantage over plain X-ray KUB, and it should not be done as a routine investigation prior to the removal of PCN tube in patients with complete stone clearance.

    Deceased donor renal transplantation (DDRT) constitutes less than 5% of all kidney transplantats in India. A retrospective analysis of 173 deceased donor renal transplants performed in a public funded government hospital was done. Mean age of the recipients was 36 years (male:female ratio 2.4:1), and that of the donors was 32.3 years (male:female ratio 6:1). The cold ischemic time was 340 ± 170 minutes. Mean follow-up period was 36 months. Forty one patients died, 75% of them in the first post – transplant year. Sepsis and cardiovascular disease were the most common causes of death. Twenty two percent had acute rejection. There was no significant difference in the incidence in the rate of acute rejection, bacterial, fungal infections and death rate between the cohorts of induction and non induction immunosuppression. The patient and death censored graft survival at 1 year were 80 and 82.6% and at 5 years were 76 and 80% respectively. PMID:28182043

    The aim of this study is to present demographic and clinical features, MEFV mutation variations, and treatment response of a large number of pediatric familial Mediterranean fever (FMF) patients from a single tertiary centre. Moreover, we aimed to investigate the current outcome of FMF, namely frequency of amyloidosis in children with FMF. We evaluated 708 FMF patients who were followed up in our clinic and who were under colchicine treatment for at least 6 months. The data were recorded from patient records and also verified by negotiations with patients and parents. The male/female proportion of the cohort was 1.05/1 (n = 362/346). Abdominal pain (89.5%, n = 634) was the most common manifestation of FMF episodes, followed by fever (88.8%, n = 629) and arthritis (40.7%, n = 288). However, arthritis in 23 (8%) of the 288 cases was not self-limited; and they subsequently diagnosed with juvenile idiopathic arthritis in addition to FMF. Homozygote or heterozygote M694V mutation was more frequent in patients with arthritis (63.2%) and chronic arthritis (69.6%) than the whole cohort (53.8%). Erythrocyte sedimentation rate and CRP level were in high levels even during attack-free period in 13.9% (n = 97/697) and 11% (n = 78/670) of the patients, respectively. Proteinuria was found in ten patients (1.4%). Amyloidosis was confirmed by renal biopsy in only two of these cases who were homozygous for M694V and compound heterozygous for M694V/M680I. 47 (6.6%) subjects were considered as colchicine resistant. Homozygote M694V mutation was the most frequent mutation in those resistant cases (63.8%, n = 30), followed by compound heterozygote mutation of M694V/M680I (6.3%, n = 3). Homozygous M694V mutation are still the most frequent mutation and associated with the most severe clinical picture and the worst outcome in Turkish children. M694V genotype seems to be more frequently associated with arthritis as well as with chronic arthritis than other genotypes. Recurrence of FMF episodes as well as amyloidosis could only be managed via strict compliance to colchicine treatment. Frequency of amyloidosis significantly decreased compared to the previous studies. A favorable outcome could be obtained with the anti IL-1 in colchicine-resistant FMF patients.

    Results: One of our 105 patients with BD was found to have solid tumor in the rate of 0.9 %. The remaining 104 patients with BD were in follow up without any malignancy in this period. The malignancy that we reported was invasive right breast carcinoma in a 55-year-old woman with BD. A radically modified right mastectomy and axillary lymphadenectomy were performed and postoperative doxorubicin, cyclophosphamide therapy for four cycles and hormonal therapy with tamoxifen and leuprolide acetate was administered as adjuvant therapy. This patient had a history of 16 years colchicine usage as medication for BD. Conclusion:The rheumatologic diseases can predispose malignancy, the autoimmune nature of BD or the immunosupressive medicines could be possible causes of this carcinoma. However, in our study only one patient had malignancy. The another point of view; management and also prevention of cancer with BD is important entity.

    Laryngeal cancer is about the twentieth most common cancer in the world and more than 150,000 new cases are diagnosed annually. The aim of the study was to evaluate the history, diagnostics, treatment outcomes, and prognosis in patients with laryngeal cancer in Northern Slovakia. We analyzed retrospectively 227 patients (207 males, 20 females) with laryngeal carcinoma treated in the period 2003-2014 at the Clinic of Otorhinolaryngology and Head and Neck Surgery of the Jessenius Faculty of Medicine and Martin University Hospital in Martin, Slovakia. The majority of patients were in the sixth (38.0 %) and seventh decade of life (30.8 %). Two hundred and seventeen patients (95.6 %) were smokers or ex-smokers. Sixty-six percent of patients were diagnosed with glottic or transglottic carcinoma, related probably to the anatomical structure of the larynx and exposure to inhalation pollutants. It is alarming that the majority of patients with malignant laryngeal disease were admitted to the hospital in advanced stages. In 151 (66.5 %) of patients, the extent of infiltration was T3 or T4, and 156 (68 %) patients were in disease stage III and IV. The incidence and mortality of laryngeal cancer suggest the need to intensify the prevention and to search for an early clinical stage of laryngeal cancer using a targeted screening.

    Many studies have investigated preexistent renal disease during pregnancy. However, insufficient data regarding the new onset of glomerulonephritis in the course of gestation, especially in patients with preeclampsia, exist. The aim of this study was to investigate underlying renal disease in preeclamptic Turkish women with persistent proteinuria after delivery. Between 2005 and 2010, 463 patients with preeclampsia were admitted to our hospital. The symptoms of proteinuria persisted in 34 women (0.7 %). Thirteen of these patients refused a kidney biopsy. Seven of these patients had a history of documented kidney disease. Kidney biopsies were performed on 14 women who were diagnosed with persistent proteinuria in the postpartum period and the specimens were examined by light and immunofluorescence microscopy. Ten of 14 patients (71 %) were diagnosed with underlying renal disease. Four patients were diagnosed with idiopathic preeclampsia (29 %). Histopathological findings existed for ten patients with underlying renal disease; four patients (29 %) were diagnosed with membranoproliferative glomerulonephritis (MPGN), four patients (29 %) were diagnosed with IgA nephropathy (IgAN), one patient (7 %) was diagnosed with focal segmental glomerulosclerosis (FSGS), and one patient (7 %) was diagnosed with amyloidosis. Hematuria was detected in eight patients (57 %), and high serum creatinin levels were observed in five (36 %). Persistent proteinuria is the most important predictor of underlying renal disease after delivery. All patients with preeclampsia should be evaluated with respect to continuing proteinuria, persistent hematuria, or impaired renal functions after postpartum period and a percutaneous renal biopsy should be performed in those patients who have positive signs of underlying renal disease.

    Full Text Available Malaria has protean clinical manifestations and renal complications, particularly acute renal failure that could be life threatening. To evaluate the incidence, clinical profile, out-come and predictors of mortality in patients with malarial acute renal failure, we retrospectively studied the last two years records of malaria induced acute renal failure in patients with peripheral smear positive for malarial parasites. One hundred (10.4% (63 males, 37 females malaria induced acute renal failure amongst 958 cases of acute renal failure were evaluated. Plasmodium (P. falciparum was reported in 85%, P. vivax in 2%, and both in 13% patients. The mean serum creatinine was 9.2 ± 4.2 mg%, and oligo/anuria was present in 82%; 78% of the patients required hemodialysis. Sixty four percent of the patients recovered completely, 10% incompletely, and 5% developed chronic kidney failure; mortality occurred in 21% of the patients. Low hemoglobin, oligo/anuria on admission, hyperbilirubinemia, cerebral malaria, disseminated intravascular coa-gulation, and high serum creatinine were the main predictors of mortality. We conclude that ma-laria is associated with acute renal failure, which occurs most commonly in plasmodium falci-parum infected patients. Early diagnosis and prompt dialysis with supportive management can reduce morality and enhance recovery of renal function.

    Full Text Available Objectives: There is paucity of information regarding clinical profile of hypopituitarism from India. We report the clinical profile of hypopituitarism from a tertiary center in North India. Materials and Methods: This study was carried out in patients attending our endocrine center between January 2010 and December 2011. All new patients were studied prospectively and those registered before January 2010 retrospectively. Relevant clinical, hormonal, and imaging data were collected. Dynamic testing for pituitary functions was carried out as necessary. Hormonal deficiencies were defined as per prevailing recommendations. Results: This study included 113 subjects. The mean age was 38.6 ± 17.8 years (range, 4 - 76 years. There were 78 (69% males and 35 females (31%. There were 22 subjects aged ≤18 years (childhood and adolescence and 91 adults (>18 years. Visual disturbances were the most common presenting complaint (33%, though headache was the most common symptom (81%. Fifteen percent presented with pituitary apoplexy. Tumors comprised of 84% of cases. Hypogonadism (97% was the most common abnormality seen followed by hypothyroidism (83.2%, hypoadrenalism (79.6%, growth hormone deficiency (88.1% of the 42 patients tested, and diabetes insipidus (13.3%. Panhypopituitarism was seen in 104 (92% patients. There were no cases of hypopituitarism secondary to traumatic brain injury, subarachnoid hemorrhage, central nervous system infections, or cranial irradiation to extrasellar tumors. Conclusion: The most common cause of hypopituitarism at tertiary care center is pituitary tumors and the commonest presenting complaint is visual symptoms. Panhypopituitarism is present in 92% cases.

    Full Text Available This study aimed to elucidate the clinical and prognostic characteristics of a homogeneous group of patients with cancer of unknown primary (CUP. Between 1999 and 2014, CUP was diagnosed in 159 (1.3% of 11,742 cancer patients at Trakya University Hospital (Edirne, Turkey. Ninety-seven (61% of the 159 patients were retrospectively reviewed. Among these, 61 (62.8% patients with adenocarcinoma were included in this study. The most frequently predicted primary tumor site was the lung (37.7%, and 59% of the patients were smokers. There was a significant relationship between smoking and the lung as a potential primary cancer site (p = 0.042. The most frequent site of metastasis was the liver (60.7%. The median number of metastases per patient was two, but patients with liver metastases had a median of five metastases. The overall median survival time was 7 months. Median survival was significantly longer in patients with a predicted primary site than in patients without the predicted site (7 vs. 6 months, respectively; p = 0.038. When the patients with predicted ovarian and peritoneal tumors were excluded from the comparison, the statistical p value was still close to significant (p = 0.07. Multivariate analysis revealed that smoking, liver metastasis, serum alkaline phosphatase ≥92 U/L, and progression in response to chemotherapy were independent predictors of a poor prognosis. The present study identified several independent prognostic factors in patients with unknown primary adenocarcinomas who received chemotherapy. Smoking, the presence of liver metastasis, and response to chemotherapy were independent risk factors for both progression-free and overall survival.

    Aging population has been increasing worldwide. So the number of elderly patients presenting with kidney disease has also been increasing. In this retrospective study, we assessed biopsy results of elderly patients and their clinical presentations. Native renal biopsy results of 98 elderly patients (≥65 years) were analyzed. These 98 patients consisted of 56 males (57.1 %) and 42 females (42.9 %) with a mean age of 70.59 ± 5.31 years (65-88 years). The clinical presentations of our elderly patients were nephritic syndrome (n = 45), acute kidney injury (n = 35), nephrotic syndrome (n = 33), chronic kidney disease (n = 32) and combined nephritic and nephrotic syndrome (n = 14). In patients with nephritic syndrome, the most common diagnosis was crescentic GN (17.8 % type 3 and 13.3 % types 1 and 2). Crescentic GN was also the most frequent among patients with acute kidney injury (37.1 %), while membranous nephropathy was the major histopathological diagnosis in chronic kidney disease patients. In nephrotic syndrome, the most common histopathological diagnosis was AA amyloidosis. None of the patients had a major life-threatening complication. Biopsies in the elderly are as safe as in the general population. Renal biopsy should be performed to provide an accurate diagnosis and initiate specific treatment in elderly patients.

    Channelopathies are associated with mutations of genes encoding proteins creating or interacting with the specialized ion channels in myocardial cell membranes, thus forming arrhythmogenic substrate predisposing the patient to sudden cardiac death. The study focuses the clinical and ECG presentation and management of children with channelopathies in Slovakia. Twenty-two children with suspected channelopathy were admitted to Children's Cardiac Center Bratislava in the years 2007-2014. Genetic testing was made in 19 patients. Fourteen patients were symptomatic. Long QT syndrome was genetically proven in eight and catecholaminergic polymorphic ventricular tachycardia in five patients. Twenty children are treated with beta-blockers, five in combination with mexiletine or flecainide. Nine patients received implantable cardiac defibrillator and one underwent left cardiac sympathetic denervation. Both clinical presentation and genetic testing must be considered in the diagnostic and therapeutic process of channelopathies. Early diagnosis allows for adequate treatment and lifestyle modification. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available The living related donor still represents the unique source for renal transplantation in Morocco. Since 1986, 127 living related potential donors have been evaluated and 100 patients have been transplanted at the Ibn Rochd UHC in Casablanca. We retrospectively studied the potential donors and determined their profile and the exclusion criteria. The mean age at the time of donation was 37 +/- 11 years (range 18-66 years and 60% of donors were women. The predominant sources of donors were sisters, brothers and mothers of recipients in 34%, 31% and 24% respectively. Forty three percent of them were married, 20% housewives and 17% unemployed. In addition, 37% were illiterate, 45% school graduates, and 18% university graduates. Donors and recipients were incom-plete HLA match in 72.7%, identical in 19% and different in 8.3%. The cross matching test was negative in all cases. The mean plasma creatinine was 0.8 ± 0.1 mg/dL with mean creatinine clearance of 103.16 ± 18.18 mL/min.

    This study examined the long-term consequences of idealization in marriage, using both daily diary and questionnaire data collected from a sample of 168 newlywed couples who participated in a 4-wave, 13-year longitudinal study of marriage. Idealization was operationalized as the tendency for people to perceive their partner as more agreeable than would be expected based on their reports of their partner's agreeable and disagreeable behaviors. Spouses who idealized one another were more in love with each other as newlyweds. Longitudinal analyses suggested that spouses were less likely to suffer declines in love when they idealized one another as newlyweds. Newlywed levels of idealization did not predict divorce.

    Ammonia is an integral part of the nitrogen cycle and is projected to be the largest single contributor to each of acidification, eutrophication and secondary particulate matter in Europe by 2020 (Sutton et al., 2008). The impacts of NH3 also include: aerosol production affecting global radiative forcing, increases in emissions of the greenhouse gases nitrous oxide (N2O) and methane (CH4), and modification of the transport and deposition patterns of SO2 and NOx. Therefore, monitoring NH3 global distribution of sources is vitally important to human health with respect to both air and water quality and climate change. We have developed new daily and global ammonia (NH3) products from AIRS hyperspectral measurements. These products add value to AIRS's existing products that have made significant contributions to weather forecasts, climate studies, and air quality monitoring. With longer than 13 years of data records, these measurements have been used not only for daily monitoring purposes but also for inter-annual variability and short-term trend studies. We will discuss the global NH3 emission sources from biogenic and anthropogenic activities over many emission regions captured by AIRS. We will focus their variability in the last 13 years.

    Germinomas presenting with a pituitary stalk lesion and panhypopituitarism are rare in children, and their definite diagnosis is challenging. An invasive diagnostic approach, such as a transsphenoidal biopsy, is often required prior to establishing a treatment regimen. A 13-year-old female presented with 1 year of secondary amenorrhea, fatigue, and progressive thirst with polyuria. Laboratory work-up revealed panhypopituitarism (central hypothyroidism, hypogonadotropic hypogonadism, adrenal insufficiency and central diabetes insipidus). α-Fetoprotein and β-human chorionic gonadotropin were not elevated in serum nor in cerebrospinal fluid. The magnetic resonance imaging (MRI) of the pituitary region showed an enhancing infundibular lesion, extending into the hypothalamus, and infiltrating the pituitary gland. A transsphenoidal biopsy of the infundibular lesion confirmed the diagnosis of germinoma (germ-cell tumor). After appropriate hormone replacement therapy, chemotherapy and low-dose radiation therapy, the patient achieved complete resolution of the pituitary stalk lesion on the MRI.

    Full Text Available Background/objectives: Congenital hypothyroidism is one of the most common preventable causes of mental retardation in children. The prognosis of infants detected by neonatal screening and started on treatment early is excellent, with intelligence quotients similar to sibling or classmate without the disease. Setting: Department of ENT, Head and Neck Surgery, KVG Medical College, Sullia. 1Case report: A 15 year old boy came with history of head ache, generalized body ache and lack of concentration in school. He was a case of congenital hypothyroidism and was on irregular treatment for the last 13 years. Intervention: The patient was advised strictly to continue the oral l-thyroxine 100μg one hour before food and come for regular follow-up. Conclusion: Definite intellectual deterioration is seen if oral l-thyroxine is not started within 50 days of life and the deterioration is irreversible. So in India newborn screening programs should be implemented as a national program as it is very important to diagnose and treatcongenital hypothyroidism as soon as possible and to treat it effectively.

    Full Text Available Rothmund-Thomson syndrome (RTS is a rare autosomal recessive disorder presenting with poikiloderma and other clinical features, affecting the bones and eyes and, in type II RTS, presenting an increased risk for malignancy. With about 300 cases reported so far, we present a 13-year follow-up including clinical images, X-rays and genetic analysis. A 13-month-old female started with a facial rash with blisters on her cheeks and limbs at the age of 3 months along with congenital hypoplastic thumbs, frontal bossing and fine hair, eyebrows and eyelashes. The patient was lost to follow-up and returned 12 years later with palmoplantar hyperkeratotic lesions, short stature, disseminated poikiloderma and sparse scalp hair, with absence of eyelashes and eyebrows. Radiographic analysis showed radial ray defect, absence of the thumb and three wrist carpal bones, and reduced bone density. Gene sequencing for the RECQL4 helicase gene revealed a mutation on each allele. RTS is a rare disease, and in this patient we observed the evolution of her skin lesions and other clinical features, which were important for the classification of type II RTS. The next years will provide even more information on this rare disease.

    This paper reports on an autopsied case manifesting an esophageal cancer that had developed 13 years after radiotherapy for lung cancer. The patient was a 61-year-old man. He was found to have a squamous cell carcinoma of the right lower bronchus with a swelling of the mediastinal and left supraclavicular lymph nodes in July of 1973. He received 60 Gy of irradiation in the right lung, the mediastinum, and the left supraclavicular region. Later, after doing well until August of 1986, a squamous cell carcinoma of the esophagus was found at the upper intrathoracic site. Thus, he also received additional radiotherapy but died of pneumonia after this local recurrence 7 months later. At autopsy, no local recurrence of the primary lung cancer was found. The site of esophageal cancer was far from that of the primary lung cancer thought it was included in the previous treatment ports. This suggests the possibility that the primary esophageal cancer had been induded by therapeutic irradiation. So far as we know, this is the first report of esophageal cancer that may have developed after irradiation for lung cancer.

METHODS: A cross-sectional epidemiological study with a multistage stratified cluster sample with 9,974 college students was conducted in the city of São Paulo, southeastern Brazil. An anonymous self-administered questionnaire was used to collect information on drug use assessed in lifetime, the preceding 12 months and the preceding 30 days. The Bonferroni correction was used for multiple comparisons of drug use rates between surveys. RESULTS: There were changes in the lifetime use of tobacco and some other drugs (hallucinogens [6.1% to 8.8%], amphetamines [4.6% to 8.7%], and tranquilizers [5.7% to 8.2%] from 1996 to 2009. Differences in the use of other drugs over the 12 months preceding the survey were also seen: reduced use of inhalants [9.0% to 4.8%] and increased use of amphetamines [2.4% to 4.8%]. There was a reduction in alcohol [72.9% to 62.1%], tobacco [21.3% to 17.2%] and marijuana [15.0% to 11.5%] use and an increase in amphetamine use [1.9% to 3.3%] in the preceeding 30 days. CONCLUSIONS: Over the 13-year study period, there was an increase in lifetime use of tobacco, hallucinogens, amphetamines, and tranquilizers. There was an increase in amphetamine use and a reduction in alcohol use during the preceding 12 months. There was an increase in amphetamine use during the preceding 30 days.

    To follow up an original research project of persons 11-13 years after stroke, in order to describe and understand the impact of stroke on everyday life experienced during these years. Eleven persons who had had a stroke were interviewed 11-13 years after the original research project. Data were collected and analysed using the empirical phenomenological psychological method. Three main characteristics were identified from analysis of participants' experiences during the years after stroke: () going through the loss of the previous life; () struggling to reclaim the former existence; () finding meaning in a "new" and different world. This study provides an understanding of the complexity of the lost connection between body and world occurring for a long time after stroke. This understanding provides support for the need for long-term and intermittent support and guidance to enable the re-creation of meaning and participation in everyday life in order to find a "new" self-identity after stroke, especially among persons with residual cognitive impairment.

    Rufinamide is a new antiepileptic drug recently approved as adjunctive treatment for generalized seizures in Lennox-Gastaut syndrome. We undertook a retrospective analysis of 77 patients with refractory epilepsy and receiving rufinamide to evaluate the drug's efficacy, tolerability, safety, and dosing schedules. It appeared efficacious in diverse epilepsy syndromes, with the highest responder rate in focal cryptogenic epilepsies (81.1% of patients with >50% response rate), and in diverse seizure types, with the highest responder rate in tonic/atonic and partial seizures (48.6% and 46.7% of patients with >50% response rate, respectively). Rufinamide was well tolerated: only 13% of patients developed side effects necessitating drug withdrawal. These findings suggest that rufinamide may possess good efficacy and tolerability, and that its efficacy may extend to epilepsy syndromes beyond Lennox-Gastaut, including both partial and generalized epilepsy syndromes.

    Purpose: To analyse the management and clinical outcome of patients treated for retroperitoneal soft tissue sarcoma and to identify prognosis factors. Patients and method: This is a retrospective study of 20 adults; 11 women and nine men treated between 1980 and 2000 in our institution. Results: There were seven lipo sarcomas and 13 leiomyo-sarcomas. The mean tumor size was 26 cm. Three patients underwent a complete resection (R0), 14 patients an incomplete resection (R1/R2) with microscopic or macroscopic tumour remained after surgery. Only three patients had a surgical biopsy. Median follow-up was 18 months. Overall survival rates was 45%, 10% at two and five years, respectively. Among the following factors, sex, age, symptom duration, tumor size, histologic type, histologic grade, resection type, mitotic index, necrosis extension, histologic differentiation, and A.J.C.C. stage, only mitotic index factor (scale 1,2 versus scale 3) significantly influenced patient survival (p = 0.02). Conclusion: This study re-emphasizes the poor outcome of patients with retroperitoneal sarcoma. Survival rates appeared low when compared with other studies. These results incite for a more aggressive approach. (authors)

    Full Text Available Abstract Background An estimated up to 7% of high-risk cardiac surgery patients return to the operating room for bleeding. Aprotinin was used extensively as an antifibrinolytic agent in cardiac surgery patients for over 15 years and it showed efficacy in reducing bleeding. Aprotinin was removed from the market by the U.S. Food and Drug Administration after a large prospective, randomized clinical trial documented an increased mortality risk associated with the drug. Further debate arose when a meta-analysis of 211 randomized controlled trials showed no risk of renal failure or death associated with aprotinin. However, only patients with normal kidney function have been studied. Methods In this study, we look at a single center clinical trial using patients with varying degrees of baseline kidney function to answer the question: Does aprotinin increase odds of death given varying levels of preoperative kidney dysfunction? Results Based on our model, aprotinin use was associated with a 3.8-fold increase in odds of death one year later compared to no aprotinin use with p-value = 0.0018, regardless of level of preoperative kidney dysfunction after adjusting for other perioperative variables. Conclusions Lessons learned from our experience using aprotinin in the perioperative setting as an antifibrinolytic during open cardiac surgery should guide us in testing future antifibrinolytic drugs for not only efficacy of preventing bleeding, but for overall safety to the whole organism using long-term clinical outcome studies, including those with varying degree of baseline kidney function.

    To summarize our single-center experience with liver transplantation (LT) for biliary atresia (BA). From October 2006 to December 2012, 188 children with BA were analyzed retrospectively. The stage I group (from October 2006 to December 2010) comprised the first 74 patients, and the stage II group (from January 2011 to December 2012) comprised the remaining 114 patients. Finally, 123 liver transplants were performed in 122 (64.9%) patients, whereas 66 patients did not undergo LT due to denial by their parents or lack of suitable liver grafts. The selection of graft types depended on the patients' clinical status and whether a suitable living donor was available. The characteristics of patients in stages I and II were described, and the surgical outcomes of LT recipients were compared between the two stages. The Kaplan-Meier method was used to estimate the cumulative patient and graft survival rates, and the equality of survival distributions was evaluated using the log-rank test. The 188 children consisted of 102 boys and 86 girls. Their ages ranged from 3 to 144 mo with a median of 8 mo. One hundred and fifteen (61.2%) patients were born in rural areas. Comparing stage I and stage II patients, the proportion of patients referred by pediatricians (43.2% vs 71.1%, respectively; P transplantation recipients (n = 102), the incidence of surgical complications was significantly reduced (34.1% vs 15.5%, respectively; P = 0.029) and survival rates of patients and grafts were greatly improved (81.8% vs 89.7%, respectively, at 1 year; 75.0% vs 87.8%, respectively, at 3 years; P = 0.107) from stage I to stage II. The status of surgical treatments for BA has been changing in mainland China. Favorable midterm outcomes after LT were achieved as centers gained greater technical experience.

    to determine the prevalence of restless legs syndrome (RLS) in a cohort of patients with demyelinating neuropathies. Patients were retrospectively recruited from our cohort of different forms of demyelinating neuropathies, including chronic inflammatory demyelinating neuropathy (CIDP), Charcot-Marie-Tooth 1A (CMT1A), and hereditary neuropathy with liability to pressure palsies (HNPP) referred to our Department of Neurology in a 10-year period. The validated 4-item RLS questionnaire was used for diagnosis of RLS. All patients with RLS who fulfilled criteria underwent a suggested immobilization test to confirm the diagnosis. A group of outpatients referred to the sleep disorders unit and data from published literature were used as controls. Prevalence of RLS in demyelinating neuropathy group was higher than prevalence observed in control population (p = 0.0142) or in the literature data (p = 0.0007). In particular, in comparison with both control population and literature data, prevalence of RLS was higher in CIDP group (p = 0.0266 and p = 0.0063, respectively) and in CMT1A group (p = 0.0312 and p = 0.0105, respectively), but not in HNPP (p = 1.000 and p = 0.9320, respectively). our study confirms a high prevalence of RLS in inflammatory neuropathies as CIDP and, among inherited neuropathies, in CMT1A but not in HNPP. Considering that this is only a small cohort from a single-center retrospective experience, the link between RLS and neuropathy remains uncertain, and larger multicenter studies are probably needed to clarify the real meaning of the association between RLS and neuropathy.

    Accompanying rapid developments in hepatic surgery, the number of surgeries and identifications of histological types of primary hepatic space-occupying lesions (PHSOLs) have increased dramatically. This has led to many changes in the surgicopathological spectrum of PHSOLs, and has contributed to a theoretical basis for modern hepatic surgery and oncological pathology. Between 1982 and 2009 at the Eastern Hepatobiliary Surgery Hospital (EHBH) in Shanghai, 31 901 patients underwent surgery and were diagnosed as having a PHSOL. In this paper, we present an analysis of the PHSOL cases at the EHBH for this time period, along with results from a systematic literature review. We describe a surgicopathological spectrum comprising more than 100 types of PHSOLs that can be stratified into three types: tumor-like, benign, and malignant. We also stratified the PHSOLs into six subtypes derived from hepatocytes; cholangiocytes; vascular, lymphoid and hemopoietic tissues; muscular, fibrous and adipose tissues; neural and neuroendocrine tissues; and miscellaneous tissues. The present study provides a new classification system that can be used as a current reference for clinicians and pathologists to make correct diagnoses and differential diagnoses among various PHSOLs.

    Full Text Available To evaluate the peritoneal dialysis (PD program in our hospital, we retrospectively studied all patients dialyzed with this modality over the last 5 years. A total of 56 patients having end-stage renal disease (ESRD, with mean age ± SD of 49 ± 20 years (range 16-92 years, were dialyzed with PD: 38 (68% patients with continuous ambulatory PD and 18 (32% patients with automated PD. Twenty-six (46% patients were females. The mean follow-up time of these patients was 17 ± 14 months. The underlying etiologies for ESRD in these patients were diabetes mellitus (48%, glomerulonephritis (9%, and hypertension (7%. Twenty-seven patients (48% were put on PD from the start, while 29 (52% patients were switched from hemodialysis (HD to PD. Nineteen (34% patients developed a total of 29 episodes of peritonitis. The incidence of peritonitis was 0.4 episode per patient-year. Exit-site infections occurred in 17 (30% patients. No tunnel infection was observed during the study period. Non-infectious catheter-related complications occurred in 12.5% of the patients; six (11% patients had hernia (umbilical or inguinal. At the end of the study, 23 (41% patients continued on PD, 17 (30% received a renal transplant, 7 (13% suffered technique failure and subsequently switched to HD, and 9 (16% patients died. To conclude, our study demonstrates that the rate of PD related complications is found to be quite low in our program, with an acceptable technique failure rate and mortality. Therefore, PD is a safe and an effective treatment modality in the integrated care approach to patients with ESRD.

    Full Text Available Background/Aim. Necrotizing fasciitis (NF is usually an acute infection of superficial fascia with rapid progression in around soft tissue. If not promptly recognized and aggressively treated NF usualy leads to sepsis and multiorgan failure with fatal outcome, thus early diagnosis and prompt surgical treatment are crucial for healing of these patients. The aim of this article was to evaluate the clinical presentation of all patients with acute NF diagnosed and treated in surgical clinics of Clinical Center of Vojvodina, Novi Sad, Serbia. Methods. The medical records of patients treated for acute NF localized on a different parts of the body in Clinical Center of Vojvodina, Novi Sad, Serbia, during a 5- year period (from January 2008 to December 2012 were retrospectively evaluated. This study enrolled patients admitted via Emergency Center of Vojvodina with the diagnosis of acute NF either as the primary diagnosis or with the diagnosis at discharge after surgical treatment. Results. During a 5-year period there were 216 patients with final diagnosis of acute NF. Most of our patients (140 - 64.81% were admitted with the initial diagnosis of cellulitis, abscesses, phlegmons or sepsis. Unfortunately, the clinical symptoms of acute NF were atypical at time of initial examination. Pain and swelling of the affected localization were the most presented bias of symptoms (183 - 84.72%. The majority of our patients were male (164 - 75.92%. Among the 216 patients, the most common pre-existing single factor was drug abuse (39 - 18.05%, followed by obesity (38 - 17.59% and diabetes mellitus (31 - 14.35%. Trauma was most common etiological factor (22 - 10.8% in infected wounds, followed by abdominal (15 - 6.94% and orthopedic (11 - 5.09% surgical intervention. In the present study idiopathic acute NF was diagnosed in 22 (10.18% patients and more than one etiological factor were diagnosed in 20 (9.25% patients. The majority of our patients had type I acute NF (172 - 79.62% with Streptococcal species as the most common microorganism (125 - 71.02%. The most common localization was an extremity (151 - 69.90%. The minority of our patients had head and neck localization of infection (7 - 3.24%. Surgical treatment was performed in all the patients and most of them (183 - 84.72% received the first surgery within 24 h. Other patients (23 - 10.64% received operation after stabilization of general status or after getting the diagnosis of acute NF (unclear diagnosis on admission. During hospitalization, the most common complication among our patients was sepsis (156 - 72.22%. The mortality rate was 14.35%. Conclusion. Acute NF is a rare but very difficult and sometimes life-threatening disease of superficial fascia and around soft tissue. If acute NF is suspected, early radical excision of all the affected tissue with exploration and excision of superficial fascia with pathological and microbiological assessment are most significant for treatment. Appropriate antibiotics and intensive care setting to manage other organ failure of NF are recommended at the same time with surgery.

    2012-01-01

    Full Text Available Background/Aim. Nowadays development of techniques enables detection of hearing impairment in a very short time, immediately after birth by using otoacoustic emissions. They are low-pitched sounds produced in physiologically clear cochlea and can be recorded in cochlear outer meatus. By this method, complete data are found on a whole presynaptic auditory nervous system functioning that has mostly been affected by pathological changes making it a perfect screening test. Reliability and sensibility of this method is up to 98%. The aim of this study was to present the first results of systematic neonatal screening of hearing function by otoacoustic emissions in the Clinical Center Kragujevac (Kragujevac, Serbia. Methods. This prospective study of neonatal hearing screening function, initiated systematically by the 2008 at the Clinical Center Kragujevac, included full-term newborns and premature born ones, within the first 24 h after birth, using a DPOAEs interacoustics otoread-screener. Retesting was done after a month. Results. From January 1st, 2009 to December 1st, 2010, a total number of examined infants by this method was 1,994 out of which 1,778 were full-term and 216 were premature born. The test passing was higher in the group of full-term babies (92.5% than in the preterm ones (55.1%. No bilateral answers were recorded in premature born children compared to the full-term ones, of whom a larger number was with missing lateral responses. The results of re-examination test in the group of full-term born and premature newborns were 83.7%, and 61%, respectively. Conclusion. Deliberately provoked transient otoacoustic emission is an efficient method in testing hearing function in newborns, since it is non-invasive, rapid and objective. Its correlation with audibly evoked potentials is very high, which confirms its reliability.

    Full Text Available Objective: In recent years several techniques have been recommended for intussusception treatment. In this study, an evaluation was made of intussusception cases that presented at our clinic and had reduction applied together with saline under ultrasonography (USG and cases, which were surgically treated. Patients and Methods: A retrospective evaluation was made of the records of 72 cases treated for a diagnosis of intussusception between January 2010 and July 2012. Patients were evaluated demographics, clinical presentation, management strategy, during the hospitalisation and outcome. Results: A total of 72 cases which consists of 44 male and 28 female with age range between 5 and 132 months were treated with a diagnosis of intussusception. USG was applied to all cases on initial presentation. As treatment, hydrostatic reduction (HR together with USG was applied to 47 cases. Of these, the HR was unsuccessful in 13 cases. Surgical treatment was applied to 38 cases. Of these cases, ileocolic intussusception was observed in 30 cases, ileoileal in seven cases and colocolic in one case. Meckel diverticulum was determined in five of these cases, polyps in two cases, lymphoma in two cases, lymph nodule in one case and 28 cases were observed to be idiopathic. There was no mortality in any case. Conclusion: HR together with USG is a safe technique in the treatment of intussusception, which also shortens the duration of hospitalisation and significantly reduces the treatment costs.

    Full Text Available Aim: Families of children with acute urticaria often think that there is food allergy in children with urticaria and insist for skin tests. In this study, it was aimed to determine whether skin prick tests are necessary in cases presented with acute urticaria, in whom other causes of acute urticaria are excluded. Material and Method: A test panel involving cow milk, egg white, wheat, hazelnut, peanut, soybean, walnut, sesame, and tuna fish antigens was applied to the children presented with acute urticaria between 1 August 2013 and 1 August 2014, in whom other causes of acute urticaria were excluded and suspected food allergy was reported by parents. Results: Overall, 574 children aged 1-14 years were included to the study. Of the patients, sensitization against at least one food antigen was detected in 22.3% (128/574 of the patients. This rate was found to be 31.9% among those younger than 3 years, while 19.3% in those older than 3 years. Overall, sensitization rates against food allergen in panel were as follows: egg white, 7.3%; wheat, 3.3%; cow milk, 2.7%,; sesame, 2.8%; hazelnut, 2.4%; soybean, 2.3%; peanut, 1.9%, walnut, 1.6%; tuna fish, 1.6%. In general, the history of patients wasn%u2019t compatible with food sensitization detected. Discussion: Sensitization to food allergens is infrequent in children presented with acute urticaria, particularly among those older than 3 years despite expressions of parent and skin prick tests seems to be unnecessary unless strongly suggestive history is present.

    A comparison was made of the outcomes after transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (AVR) in high-risk patients. All patients aged > 75 years that underwent a procedure for severe aortic stenosis with or without coronary revascularization at the authors' institution were included in the study; thus, 64 patients underwent TAVI and 188 underwent AVR. Patients in the TAVI group were older (mean age 84 +/- 5 versus 80 +/- 4 years; p < 0.0001) and had a higher logistic EuroSCORE (p = 0.004). Six patients (9%) died during the procedure in the TAVI group, and 23 (12%) died in the AVR group (p = 0.5). Predictors for mortality were: age (p < 0.0001), female gender (p = 0.02), and surgical valve replacement (p = 0.01). Gradients across the implanted valves at one to three months postoperatively were lower in the TAVI group (p < 0.0001). Actuarial survival at one, two and three years was 78%, 64% and 64%, respectively, for TAVI, and 83%, 78% and 75%, respectively, for AVR (p = 0.4). Age was the only predictor for late mortality (p < 0.0001). TAVI patients were older and posed a higher predicted surgical risk. Procedural mortality was lower in the TAVI group, but mid-term survival was similar to that in patients undergoing surgical AVR. Age was the only predictor for late survival. These data support the referral of high-risk patients for TAVI.

    Full Text Available Introduction: Information on the time course of serum parathormone levels after renal transplantation is scanty. Both the abrupt cessation of calcium-containing phosphorus binders and vitamin D (analogs at the time of surgery and the recovery of renal function may be hypothesized to affect parathyroid gland. This study firstly examined frequency distribution of various biochemical parameters such as alkaline phosphatase (ALP, phosphorus (P, intact parathormone (iPTH and calcium (Ca in renal transplanted patients and secondly examined the relationship between these parameters and various demographic data of renal transplanted recipients. Material and Methods: we studied 72 renal transplanted patients (47 men and 25 women with mean ages of 44 ± 12 years and mean body mass index of 24.2 ± 3.9. Serum Ca, P, ALP and serum iPTH were measured. Results: In this study, mean serum Ca and iPTH were 9.5 ± 0.7mg/dL and18.4 ± 8.2 Pg/mL (median=16.5. Mean serum ALP was 169 ± 133 IU/L (median=131. In this study, there was a negative relationship between serum iPTH and creatinine clearance (r=-0.44 P 0.05. There were inverse correlations of serum ALP with age (r=-0.35 P= 0.02 and duration of kidney transplantation (r=-0.29 P= 0.01. Conclusions: In contrast to previous findings, in this group of patients, there was not secondary hyperparathyroism or significantly increased bone activity. The results showed suppressed parathormone secretion. The reason may be due to excessive intake of calcium and Vitamin D analogues, which suppress the parathyroid gland, and may prone these patients to adynamic bone disease.

    The aim of this study is to explore the value of transthoracic echocardiography in the diagnosis of eosinophilic myocarditis. The echocardiographic characteristics of nine patients with eosinophilic myocarditis in our hospital between January 2004 and January 2012 were retrospectively reviewed. In our study, four of the nine patients were diagnosed to have small pericardial effusion. The obliteration of the apical cavity was observed in five of the nine patients. There were six patients with both mitral and tricuspid regurgitation, one patient with only mitral regurgitation, and one patient with only tricuspid regurgitation. Transthoracic echocardiography showed that the diameters of the left and right atria were both increased in eight of the nine patients. The diameter of the left ventricle was increased in five patients, and the right ventricular diameter was increased in four patients. The left ventricular ejection fraction was decreased in two of the nine patients. Five of the nine patients had pulmonary hypertension, and one patient had severe pulmonary hypertension. Transthoracic echocardiography is the primary method for the diagnosis of eosinophilic myocarditis and is also useful in follow-up of the disease.

    In pediatric patients with acute refractory cardiogenic shock (CS), extracorporeal membrane oxygenation (ECMO) remains an established procedure to maintain adequate organ perfusion. In this context, ECMO can be used as a bridging procedure to recovery, VAD or transplantation. While being supported by ECMO, most centers tend to keep their patients well sedated and supported by invasive ventilation. This may be associated with an increased risk of therapy-related morbidity and mortality. In order to optimize clinical management in pediatric patients with ECMO therapy, we report our strategy of veno-arterial ECMO (VA-ECMO) in extubated awake and conscious patients. We therefore present data of six of our patients with CS, who were treated by ECMO being awake without continuous analgosedation and invasive ventilation. Of these six patients, four were 14 years of age. Median time on ECMO was 17.4 days (range 6.9-94.2 days). Median time extubated, while receiving ECMO support was 9.5 days. Mean time extubated was 78 % of the total time on ECMO. Three patients reached full recovery of cardiac function on "Awake-VA-ECMO," whereas the other three were successfully bridged to destination therapy (VAD, heart transplantation, withdrawal). Four out of our six patients are still alive. Complications related to ECMO therapy (i.e., severe bleeding, site infection or dislocation of cannulas) were not observed. We conclude that "Awake-VA-ECMO" in extubated, spontaneously breathing conscious pediatric patients is feasible and safe for the treatment of acute CS and can be used as a "bridging therapy" to recovery, VAD implantation or transplantation.

    Full Text Available Purpose: To determine the main causes of thyrotoxicosis and to compare the clinical and biochemical fetaures of the patients according to the underlying cause of thyrotoxicosis. Material and Method: Five hundred ninety-two patients, who were consecutively diagnosed with thyrotoxicosis, were retrospectively analysed. Symptoms of thyrotoxicosis, serum thyroid-stimulating hormone (TSH, free T3 and free T4 levels, anti-thyroglobulin autoantibody (TGAb, anti-thyroid peroxidase autoantibody (TPOAb and ultrasonographic features were recorded. To determine the cause of thyrotoxicosis, Tc-99m pertechnetate thyroid scintigraphy was performed in all patients except for pregnant women. The clinical and biochemical results were compared between the patients with different diagnosis of thyrotoxicosis. Results: 40.9% of patients were diagnosed with toxic multinodular goiter (TMNG. The other main causes of thyrotoxicosis were: Graves’ disease (GD (22%, thyroiditis (14.8%, gestational thyrotoxicosis (12.7%, and toxic adenoma (9.6%. The clinical presentation and severity of thyrotoxicosis varied according to the underlying cause. Weight loss was more frequently observed in patients with GD (p=0.0001, while cardiac arrhythmia dominated in patients with TMNG (p=0.0001. Moderate (27% or severe (23.9% thyrotoxicosis was more common in patients with GD than in patients with other forms of thyrotoxicosis (p=0.0001. Discussion: Toxic multinodular goiter is the most common cause of thyrotoxicosis in our region.

    fecal peritonitis due to colorectal perforation is a dramatic event characterized by high mortality. Our study aims at determining how results of sigmoid resection (eventually extended to upper rectum) for colorectal perforation with fecal peritonitis changed in recent years and which factors affected eventual changes. Seventy-four patients were operated on at our institution (2005-2014) for colorectal perforation with fecal peritonitis and were divided into two numerically equal groups (operated on before (ERA1-group) and after (ERA2-group) May 2010). Mannheim Peritonitis Index (MPI) was calculated for each patient. Characteristics of two groups were compared. Predictors of postoperative outcomes were identified. Postoperative overall complications, major complications, and mortality occurred in 59%, 28%, and 18% of cases, respectively, and were less frequent in ERA2-group (51%, 16%, and 8%, respectively), compared to ERA1-group (68%, 41%, and 27%, respectively; p = .155, .02, and .032, respectively). Such results paralleled lower MPI values in ERA2-group, compared to ERA1-group (23(16-39) vs. 28(21-43), p = .006). Using receiver operating characteristic analysis, the best cut-off value for MPI for predicting postoperative complications and mortality was 28.5. MPI>28 was the only independent predictor of postoperative overall (p = .009, OR = 4.491) and major complications (p peritonitis longer than 24 h (p = .045, OR = 17.099). results of surgery for colorectal perforation with fecal peritonitis have improved over time, matching a concurrent decrease of MPI values and a better preoperative patient management. MPI value may help in selecting patients benefitting from surgical treatment. Copyright © 2015 IJS Publishing Group Limited. Published by Elsevier Ltd. All rights reserved.

    Full Text Available Epidemiological data of renal diseases have great geographic variability throughout the world. Due to the lack of a national renal data registry system, there is no information on the prevalence rate, clinical and pathological features of various glomerulonephritis (GN in the United Arab Emirates (UAE. In a retrospective cross-sectional study, we analyzed 158 renal biopsies done in Dubai Hospital, UAE, between the years of 2005 and September 2014, with an aim to determine the prevalence rate and frequency of different pathological patterns of GN in adult patients who presented with proteinuria ± hematuria. In our study, primary GN still remains more common than secondary GN (66.4% vs. 33.5%. Among the primary GN in our analysis, minimal change disease was the most common primary GN affecting 20% of the study population (13.2% of the total GN causes followed with membranous GN (18.2%, then membrano- proliferative GN (15.3% and focal segmental glomerulosclerosis (13.46%, while among the secondary causes lupus nephritis (LN is the most prevalent GN in UAE, predominantly in the Emirati national population whom constituted 48% of total biopsies. Indeed, LN had the highest incidence among all types of GN even the primary ones, constituting 23.4% of total GN in Dubai (74% of the total secondary causes. Furthermore, systemic lupus erythematosus was the most common GN in women while the minimal change was widely affecting male patients. Among elderly, the most common pathology was diabetic glomerulosclerosis followed by amyloidosis.

    Full Text Available Aim: To evaluate demographic,clinical and laboratory characteristics, causes, MEFV gene mutations, and mortality rates of patients with secondary amyloidosis. Material and Method: 61 patients who had been diagnosed with secondary amyloidosis by renal and rectal biopsy between 2007 and 2013 in the nephrology clinic of Cumhuriyet University, Faculty of Medicine, were included in the study. Demographic characteristics, causes of secondary amyloidosis, MEFV gene mutations, end-stage renal failure (ESRF, renal transplantation, and mortality rates were examined retrospectively. Results: In etiological terms, Familial Mediterranean Fever (FMF occurrence was 62.2% (38, bronchiectasis and emphysema 9.8% (6, tuberculosis 4.9% (3, coexistence of FMF and ankylosing spondylitis 3.2% (2, coexistence of FMF and rheumatoid arthritis 1.6% (1, coexistence of FMF and systemic lupus erythematosus (SLE 1.6% (1, osteomyelitis 1.6% (1, septic arthritis 1.6% (1, Crohn%u2019s disease 1.6% (1, colon cancer 1.6% (1, coexistence of bronchiectasis and tuberculosis 1.6% (1, rheumatoid arthritis 1.6% (1, and idiopathic cases 6.5% (4. Proteinuria was determined at nephrotic level among 68% (32 of 47 patients who had secondary amyloidosis. MEFV gene mutation of 45 patients with secondary amyloidosis was assessed. Most patients had M694V gene mutation. Surprisingly, we detected heterozygous E148Q mutation in 3 cases. 12 cases died; of these, 9 had ESRF. Five cases with ESRF underwent renal transplantation. Discussion: We found FMF as the most common cause for secondary AA amyloidosis in this study. Further studies should be done with larger or multicenter cohorts.

    It is estimated that 30-50% of patients suffering from deep vein thrombosis (DVT) could be diagnosed with congenital or acquired thrombophilia. Its diagnosis, however, rarely changes the clinical management, but is associated with significant costs and negative psychological and social aspects. The aim of this study was to perform a retrospective analysis of the causes and clinical consequences of diagnostics for thrombophilia. A retrospective review of the medical records of 5600 patients was performed, 62 of whom had, at the time, been diagnosed for thrombophilia because of a thromboembolic event. A review of the current literature on the validity of diagnostic tests for hypercoagulability in certain clinical conditions was also performed. The most common reason for thrombophilia testing was episodes of lower limb DVT (56%). The most frequently diagnosed abnormalities were the heterozygous form of the V Leiden gene (18%), protein S deficiency (11%), and the anti cardiolipin antibody IgG (11%). In 45% of the patients, laboratory results did not confirm the presence of any congenital thrombophilia. After receiving the results, 11% of the respondents completed oral anticoagulation therapy after 3 months, and 28% of patients qualified for indefinite use of oral anticoagulant therapy. In most of the cases examined, the diagnosis of thrombophilia did not significantly affect the treatment. A common aberration identified in patients with a history of thromboembolic incidents was the coexistence of risk factors for atherosclerosis.

    Pregnancy is a normal physiological state that predisposes to thrombosis, determined by hormonal changes in the body. These changes occur in the blood flow (venous stasis), changes in the vascular wall (hypotonia, endothelial lesion) and changes in the coagulation factors (increased levels of factor VII, factor VIII, factor X, von Willebrand factor) and decreased activity levels of natural anticoagulants (protein C, protein S). In this study, we tried to determine a possible association between thrombosis and inherited thrombophilia in pregnant women. This is a retrospective study of 151 pregnant women with a history of complicated pregnancy: maternal thrombosis and placental vascular pathology (intrauterine growth restriction, preeclampsia, recurrent pregnancy loss), who were admitted in our hospital during the period January 2010 to July 2014. We performed genetic analyses to detect the factor V Leiden mutation, the G20210A mutation in the prothrombin gene, the C677T mutation and the A1298C mutation in methylenetetrahydrofolate reductase (MTHFR) gene. The risk of thrombosis in patients with factor V Leiden is 2.66 times higher than the patients negative for this mutation (OR 2.66 95% CI 0.96-7.37 P=0.059). We did not find any statistical association with mutations in the MTHFR gene. Pregnant women with a family history of thrombosis present a 2.18-fold higher risk of thrombosis (OR 2.18 CI 0.9-5.26 P=0.085). Of 151 pregnant women, thrombotic events occurred in 24 patients: deep vein thrombosis, pulmonary embolism, cerebral venous sinus thrombosis and ischemic stroke. The occurrence of thrombotic events was identified in the last trimester of pregnancy, but especially postpartum. Thrombosis in pregnancy is a redoubtable complication requiring an excellent cooperation between the obstetrician and anesthesiologist.

    The purpose of this study was to characterize differences in the prevalence of hereditary and acquired thrombophilia in patients with splanchnic vein thrombosis (SVT). A total of 88 consecutive patients with SVT, including Budd Chiari Syndrome (n = 47) and portal extrahepatic portal vein obstruction (n = 41), underwent comprehensive thrombophilia testing, including testing for heritable and acquired causes. In 33 (37.5%) patients, etiology could be explained by at least 1 of the heritable etiologic factors, and 31 (35.2%) patients could be explained by at least 1 of the acquired causes studied. The combination of multiple concurrent factors was present in 9 (11.4%) patients. Among the heritable causes, the risk of SVT was found increased in the presence of thrombophilia resulting from the deficiencies of the naturally occurring anticoagulant proteins, and the acquired thrombogenic factors were significantly associated with causation of thrombosis in adult patients with SVT.

    Full Text Available Background and Aim. Advanced chronic kidney disease (CKD severely impairs life expectancy and quality of life in affected patients. Considering its benefits, renal transplantation currently represents the optimal treatment solution for end stage kidney disease patients. Pre-transplant assessment aims to maximize the graft and patient survival by identifying potential factors influencing the post-transplant outcome. The aim of this study has been to analyze recipient related prognostic factors bearing an impact on graft survival. Material and Methods. We analyzed the graft outcomes of 426 renal transplantations performed at the Clinical Institute of Urology and Renal Transplantation of Cluj-Napoca, between January 2004 and December 2008. Variables related to recipient and to potential donor/recipient prognostic factors were studied using univariate and multivariate analysis. Results. Graft survivals at 1, 3, 5 and 7 years were 94.01%, 88.37%, 82.51% and 78.10%, respectively. Chronic rejection (41.11% and death with a functioning graft (18.88% were the main causes of graft loss. In uni and multivariate analysis the recipient related variables found to influence the renal graft outcome were: peritoneal dialysis, pre transplant residual diuresis, grade I hypertension, severe iliac vessel atheromatosis, ischemic heart disease, stroke history, dyslipidemia and denutrition. The worst graft outcomes have been found for recipients on peritoneal dialysis, with anuria, hypotension, severe iliac atheromatosis, ischemic heart disease, stroke history, dyslipidemia and a poor nutritional status. Conclusion. The type of dialysis, the pre transplant residual diuresis, recipient arterial blood pressure, iliac vessel atheromatosis, ischemic heart disease, stroke history, dyslipidemia and denutrition significantly influence graft survival.

    Background Since the inception of robotic mitral valve repair (MV) in 2007 at our institution, it has become an acceptable surgical option with proven efficacy and safety. The objective of this study is to analyze the early and long-term clinical outcomes of patients undergoing robotic MV repair. Methods A total of 310 patients (aged 48.4±13.7 years, 201 males) undergoing robotic MV repair using the da Vinci system (Intuitive Surgical, Inc., Sunnyvale, CA) between August 2007 and December 2015 in our institution were evaluated. The preoperative demographics, operative profiles and postoperative outcomes including follow-up echocardiographic results were analyzed. Results Successful MV repair was achieved in 98.4% (n=305) of patients, with no significant residual mitral regurgitation (MR) postoperatively. There were no early postoperative deaths. Early postoperative complications included: stroke (n=3, 1.0%), new onset dialysis (n=1, 0.3%) and reoperation (n=3, 1.0%). During a median follow-up of 55.7 months (inter-quartile range 30.3 to 81.3 months), six (1.9%) patients died, while four patients underwent late reoperation for mitral regurgitation (n=2) or infective endocarditis (n=2). Major event-free survival at five years was 87.6%. Late echocardiographic profiles (>6 months) were obtained in 295 (95.2%) patients. During follow-up, 32 (10.8%) patients developed significant mitral regurgitation (MR > grade 2), while freedom from significant MR at five years was 86.5%. Conclusions Robotic MV repair is a safe procedure with acceptable postoperative results, including low early postoperative morbidity and mortality and acceptable long-term repair durability.

    Methods : Retrospective review of medical records of seven neonates who underwent Norwood procedure at our institute from October 2010 to August 2012. Results: The median age at surgery was 9 days (range 5-16 days. All cases were done under deep hypothermic cardiopulmonary bypass and selective antegrade cerebral perfusion. The median cardiopulmonary bypass (CPB time was 240 min (range 193-439 min and aortic cross-clamp time was 130 min (range 99-159 min. A modified Blalock-Taussig (BT shunt was used to provide pulmonary blood flow in all cases. There were two deaths, one in the early postoperative period. The median duration of mechanical ventilation was 117 h (range 71-243 h and the median intensive care unit (ICU stay was 12 days (range 5-16 days. Median hospital stay was 30.5 days (range 10-36 days. Blood stream sepsis was reported in four patients. Two patients had preoperative sepsis. One patient required laparotomy for intestinal obstruction. Conclusions:Stage one Norwood is feasible in a limited-resource environment if supported by a dedicated postoperative intensive care and protocolized nursing management. Preoperative optimization and prevention of infections are major challenges in addition to preventing early circulatory collapse.

    Full Text Available Background: To determine the incidence and demographic characteristics of skin diseases presenting with hyperpigmentation in children applying to the dermatology department. Methods: A total of 2815 children between the ages of 0 to 16 who applied to the dermatology clinic with the complaints of hyperpigmentation disorders were evaluated. The age, gender, socioeconomic status, place of residence and demographic characteristics of children with abnormal pigmentation skin lesions were investigated. Results: A total of 2815 children applied to the dermatology clinic during the study period. Of these patients 1491 were female (53% and 1324 were male (47%. Of these 266 (9.4% were diagnosed with skin disorders presenting with hyperpigmention. The causes of hyperpigmentation in these patients were was follows; pityriasis alba (2.6%, melanocytic nevus (2.1%, vitiligo (1.8% postinflammatory hyperpigmentation (0.5%, and postinflammatory hypopigmentation (0.5%. According to the gender, p.alba, vitiligo, Becker nevus, acanthosis nigricans, tuberosclerosis and albinism were seen more in boys and nevus depigmentosus ephelis, postinflammatory hyperpigmentation/hypopigmentation and melanocytic nevus were seen more in the girls. Pitriyazis versicolor was seen equally in both genders. According to age groups, melanocytis nevus were found to be more frequent between the ages of 0-2 and 12-16, whereas pityrsasis versicolor was more frequent in ages 12-16 and P. alba in the 3-11 age group. Conclusions: There are quite a substantial number of pigmentation diseases occurring in children. Early diagnosis and treatment are important because although these diseases mainly cause cosmetic problems, they can decrease the quality of life. Here, we attempted to define the demographic characteristics of diseases presenting with disorders in pigmentation in children.

    2015-12-01

    Full Text Available Background and Design: Occupational contact dermatitis (OCD is responsible for 80-90% of the occupational dermatoses. The aim of this work was to evaluate the clinical features of patients with OCD admitted to our hospital. Materials and Methods: The records of patients, who were admitted to our hospital with OCD between December 2009 and January 2013, were evaluated retrospectively. One hundred fifty-nine patients, who were diagnosed with OCD according to the Mathias criteria, were included in the study. Age, sex, location of the lesions, atopic status, glove use, occupational exposure time and total IgE levels of the patients were assessed. Patients with positive allergic reaction with "European Standard Series Skin Patch Test" were identified as allergic OCD and patients with negative test results as "irritant OCD". The clinical features and patch results of patients are evaluated. Results: One hundred fifty-nine patients with a mean age of 39±7.9 years consisted of 151 men and 8 women. The hands were the most common site of OCD; the palms were the most common affected areas of hand eczema. Eighty-one patients (50.1% were identified to have allergic OCD and 78 (49.9% as irritant OCD. Irritant OCD was most commonly seen in dental technicians, whereas allergic OCD was most commonly seen in tailors. The top 3 most frequent allergens were potassium dichromate (15.1%, nickel sulfate (9.11% and cobalt chloride (10.7%. Conclusion: In our country, there has been no comprehensive study presenting the clinical and descriptive characteristics of OCD. For preventing OCD and reducing sick leave we need to have data that belong to our country. Consequently, multicenter studies should be performed for establishing our own database on OCD.

    Full Text Available The aim of the present study was to retrospectively evaluate response to therapy in 73 patients affected by systemic sclerosis (SSc who underwent long-term cyclic treatment with intravenous iloprost for peripheral vascular involvement (average duration of treatment 54.12±41.04 months. Seventy-three SSc patients were enrolled. Data were collected by reviewing clinical records and by phone or direct interview. Patients underwent a thorough physical examination at the end of follow up. The incidence of severe vascular manifestations was also assessed. Statistical analysis was performed by Wilcoxon’s signed rank test and descriptive statistics using Statview software. In this study cohort, 55 of 73 (75.2% patients had a history of ischemic digital ulcers (DUs; 28 patients (38.4% had active DUs at the beginning of treatment. Skin ulcers healed completely in 25 of 28 patients (89.3% at the end of the first treatment. However, 40 of 55 patients (72.6% relapsed after an average of 24 months. There was a significant correlation between relapse rate and/or number of ulcers and clinical factors (diffuse subset, changes in results of Allen’s test, NT-pro BNP levels. The annual incidence of pulmonary arterial hypertension (PAH was 2.34 (95%CI: 0.94-4.83 per 100 person years, the rate of gangrene was 2.7%, and no cases of scleroderma renal crisis were recorded. The incidence of PAH and of digital gangrene was higher than that observed in unselected SSc case series. These data suggest that our patients treated with iloprost have a higher vascular involvement than large case series of unselected SSc patients. A number of clinical factors are correlated to the severity of vascular involvement and could have an impact on the response to therapy. The clinical significance of these findings requires clarification and further investigation is needed.

    Blood blister-like aneurysms (BBAs) are a controversial entity. They arise from non-branching sites on the supraclinoid internal carotid artery (ICA) and are suspected to originate from a dissection. Our aim is to describe the BBA cases seen in our center and to present a systematic review of the literature on BBAs. We analyzed the eleven cases of BBA admitted to our center from 2003 to 2012. We assessed the medical history, treatment modality (endovascular and/or surgery), complications and clinical outcome. The cohort included 8 women and 4 men with a mean age of 53.16 years. Treatment of the BBA consisted of stenting and coiling in 5 patients, stenting only in 4 patients, coiling and clipping in 1 patient, clipping only in 1 patient, and conservative treatment in 1 patient. A good outcome was found in 10 patients, as defined by a modified Rankin Scale (mRS) less than or equal to two at three months. A systematic review of the literature was performed, and 314 reported patients were found: 221 patients were treated with a primarily surgical approach, and 87 patients were treated with a primarily endovascular approach. A rescue or second treatment was required in 46 patients (21%). The overall estimated treatment morbidity rate was 17%, and the mortality rate was 15%. BBAs exhibit more aggressive behavior compared to saccular aneurysms, and more intra-operative complications occur with BBAs, independent of the treatment type offered. They are also significantly more likely to relapse and rebleed after treatment. Endovascular treatment offers a lower morbidity-mortality compared with surgical approaches. Multilayer flow-diverting stents appear to be a promising strategy. Copyright © 2013 The Authors. Published by Elsevier Ireland Ltd.. All rights reserved.

    This clinical study is aiming to discuss the therapeutic benefit of laparoscopic appendectomy (LA) by comparing with conventional open appendectomy (OA) in pregnancy. The clinical data of 26 pregnant women who underwent appendectomy from 2012 to 2016 was retrospectively analyzed. The variables analyzed included baseline information, operation characteristics, maternal complications, and infant health outcomes. The patients were divided in 2 LA and OA groups according to the surgical approach and their clinical characteristics were compared. Of reported 26 patients, 7 underwent LA whereas the remaining 19 patients underwent OA. The median age of the patients was 28 years (range, 19 to 39 y). The median gestational period was 21.5 weeks (range, 5 to 33 wk). The postoperative pathology showed complicated appendicitis 7 cases. The result showed significantly shorter operation time (42.14±8.63 vs. 65.21±26.58 min, P=0.003), hospital stay (4.14±1.77 vs. 6.47±2.72 d, P=0.021), and earlier recovery of gastrointestinal function in the LA group compared with OA group. There were no maternal and fetal deaths occurred in perioperative period in both groups. LA has not increased morbidity and mortality but displayed shorter hospital stay, operation time and recovery of gastrointestinal function to OA as well as good cosmetic results. Therefore, LA in patients with pregnancy can be considered as preferred approach in sophisticated hands without increased risks.

    To evaluate children with gallstone in respect to demographic features, type of presentation, predisposing risk factors, laboratory features, complications, and outcome. Overall, 124 children with sonographically diagnosed gallstone were stratified into group 1 (symptomatic) and group 2 (asymptomatic). The data on demographic features, predisposing risk factors, laboratory features, complications, and outcome were collected from medical charts and compared by using convenient statistical methods. There were 76 (61%) children in group 1. Females were significantly older than males at the time of diagnosis (p=0.001). After adjusting for age and sex, asymptomatic presentation was associated with hemolytic anemia (r=346, Gallstone resolution was detected in 20 (29.4%) and 10 children (23.3%) in groups 1 and 2, respectively (p=0.477). Resolution was observed in 43.8% of children with ceftriaxone-associated gallstone. The rate of resolution with ursodeoxycholic acid (UDCA) was similar to that observed with expectant management. Gallstone resolution was evident in 9 infants (50.0%) and was significantly higher than children over 2 years of age (21 out of 106 children, 19.8%) (p=0.006). The most important factor associated with gallstone resolution was to be an infant (gallstones are most likely to resolve but do not always undergo spontaneous resolution. UDCA treatment seems to be ineffective. Young age is a favorable factor for gallstone resolution. The rate of complications in children with asymptomatic presentation is considerably low. Thus, clinical follow-up rather than surgical intervention is suggested in children with asymptomatic presentation and in infants.

    AIM: To identify the characteristic clinical, laboratory and radiological findings and response to treatment in patients with fascioliasis.METHODS: Patients who were diagnosed with Fasciola hepatica infection were included in this prospective study. Initial clinical, laboratory and radiological findings were recorded. All patients were followed until a complete response was achieved or for 6 mo after treatment discontinuation.RESULTS: Fasciola hepatica infection was diagnosed in 30 patients (24 females; mean age: 42.6 years) between January 2008 and February 2011. Twenty-two (73%) patients had hepatic phase fascioliasis, 5 patients had biliary phase, and 3 patients had biliary phase associated with acute pancreatitis. Of the 8 patients with biliary phase fascioliasis, 2 patients displayed features that overlapped with both hepatic and biliary phase. Abdominal pain and right upper abdominal tenderness were the most prominent signs and symptoms in all patients. Eosinophilia was the most prominent laboratory abnormality in both patients with hepatic and biliary phase (100% and 50%, respectively).Multiple nodular lesions like micro-abscesses on abdominal computerized tomography were the main radiological findings in patients with hepatic phase. Small linear filling defects in the distal choledochus were the main endoscopic retrograde cholangiopancreatography (ERCP) findings in patients with biliary phase. Patients with hepatic phase were treated with triclabendazole alone, and patients with biliary phase were treated with triclabendazole and had live Fasciola hepatica extracted from the bile ducts during ERCP.CONCLUSION: Fasciola hepatica infection should be considered in the differential diagnosis of patients with hepatic or biliary disease and/or acute pancreatitis associated with eosinophilia.

    Full Text Available Objective: The aim of this study is to determine safety and feasibility of conscious sedation using dexmedetomidine for transcatheter atrial septal defect (ASD device closure. Material and Methods: A retrospective institutional review of transcatheter ASD device closure without endotracheal intubation over 18 months. The protocol included topical oropharyngeal anesthesia using lignocaine followed by dexmedetomidine bolus 1 μg/kg intravenously over 10 min and maintenance dose 0.2-0.7 μg/kg/h. Ramsay sedation score 2-3 was maintained. Patients were analyzed regarding demographic profile, device size, procedure time, anesthesia time, recovery time, hospital stay, and any hemodynamic or procedural complications. Results: A total of 43 patients with mean age 31.56 ± 13.74 years (range: 12-56 years were analyzed. Mean anesthesia duration was 71.75 + 21.08 min. Mean recovery time was 7.6 ± 3.01 min. 16 females and one male patient required additional propofol with a mean dose of 30.8 ± 10.49 mg. No hemodynamic instability was noted. No patient required general anesthesia with endotracheal intubation. The procedure was successful in 93.02% of patients. Four patients developed atrial fibrillation. All patients were satisfied. Conclusion: Conscious sedation using dexmedetomidine is a safe and effective anesthetic technique for percutaneous ASD closure.

    Full Text Available Objectives: Atrial fibrillation (AF, the most common arrhythmia in clinical practice, is a major cause of stroke. Atrial fibrillation increases morbidity and mortality. Nowadays cryoablation therapy is being performed efficiently and safely worldwide. In this paper the clinical outcomes of the patients whom were treated with cryoablation were discussed. Methods: Between June 2012 and March 2014, patients with paroxysmal AF who were treated with cryoablation were included in the study. The medical records of the patients were retrospectively reviewed. Patients were called to receive information about the symptom recurrence. Results: Twelve patients were included in the study. Half of the patients were female. The mean age was 48 ± 15 years. Acute procedural success rate of cryoablation was 100%. In one patient transient right phrenic nerve injury occurred which was returned to normal after discontinuation of cryoablation therapy. One patient developed AF episode for 10 minutes in the 4th month of follow-up period. Conclusion: In patients with paroxysmal atrial fibrillation cryoablation effectively decrease symptoms consistent with the literature. J Clin Exp Invest 2014; 5 (4: 599-603

    Full Text Available Objective: To determine the epidemiological, clinical, laboratory characteristics as well as outcome of 411 patients with bowel obstruction in Southern Iran. Methods: This was a cross-sectional study being performed in Shahid Faghihi hospital of Shiraz between 2006 and 2012. We reviewed the medical charts of the 411 patients with initial diagnosis of bowel obstruction who were admitted to our center during the study period. The patients’ demographic, clinical and laboratory findings as well as their management and outcome was recorded in data gathering forms. The data were then analyzed according to the outcome and clinical characteristics. Results: Among the 411 patients with initial diagnosis of bowel obstruction, 253 (61.5% were men and 158 (38.5% were women. The mean age of the patients was 48.2±19.7 years. Besides, 73.6% were observed and 26.4% were operated. Those who were operated had those who underwent operation had significantly lower frequency of obstipation (28.1% vs. 71.9%; p=0.045 and abdominal distention (32.3% vs. 67.7%; p=0.007. Intraoperative findings included adhesion band formation in 50 (48.1%, mass 18 (17.3%, and hernia 7 (6.7%. We found that the frequency of malignancy was significantly higher in those who were managed conservatively compared to those undergoing operation (64.3% vs. 35.7%; p=0.042. The mean hospital stay was significantly higher in those who underwent operation (8.1±7.5 vs. 2.6±2.2 days; p=0.035. Conclusion: The results of this study demonstrates although some signs and symptoms, such as abdominal pain, vomiting, abdominal tenderness, abdominal distention, and obstipation, were more common among the patients with bowel obstruction, they were not sensitive and specific enough for definite diagnosis. Due to the lack of positive predictive value of clinical signs and symptoms in diagnosis of bowel obstruction, a reasonable and logical modality is needed for bowel obstruction diagnosis with better accuracy.

    Full Text Available Background. Patients with acute ischemic stroke due to internal carotid artery (ICA disease are at high risk of early stroke recurrence. A combination of IV thrombolysis and early carotid artery stenting (CAS may result in more effective secondary stroke prevention. Objective. We tested safety and durability of early CAS following IV thrombolysis in stroke patients with residual stenosis in the symptomatic ICA. Methods. Of consecutive patients treated with IV rtPA, those with residual ICA stenosis ≥70% or 24 hours. The protocol included pre-rtPA MRI and MR angiography, and post-rtPA carotid ultrasound and CT angiography. Stroke severity was assessed by the NIH Stroke Scale (NIHSS. Three- and twelve-month stent patency was assessed by ultrasound. Twelve-month functional outcome was assessed by the modified Rankin Scale (mRS. Results. Of 145 consecutive IV rtPA-treated patients, 6 (4% underwent early CAS. Median age was 76 (range 67–78 years, median NIHSS at stroke onset was 12 (range 9–16 and 7 (range 7-8 before CAS. Median onset-to-CAS time was 48 (range 30–94 hours. A single self-expandable stent was implanted to cover the entire lesion in all patients. The procedure was uneventful in all patients. After 12 months, all patients had stent patency, and the functional outcome was favourable (mRS ≤ 2 in all but 1 patient experiencing a recurrent stroke for new-onset atrial fibrillation. Conclusion. This small case series of a single centre suggests that early CAS may be considered a safe alternative to CEA after IV rtPA administration in selected patients at high risk of stroke recurrence.

    Full Text Available BACKGROUND: De novo cancers are a growing problem that has become one of the leading causes of late mortality after liver transplantation. The incidences and risk factors varied among literatures and fewer concerned the Eastern population. AIMS: The aim of this study was to examine the incidence and clinical features of de novo cancers after liver transplantation in a single Chinese center. METHODS: 569 patients who received liver transplantation and survived for more than 3 months in a single Chinese center were retrospectively reviewed. RESULTS: A total of 18 de novo cancers were diagnosed in 17 recipients (13 male and 4 female after a mean of 41 ± 26 months, with an overall incidence of 3.2%, which was lower than that in Western people. Of these, 8 (3.32% cases were from 241 recipients with malignant liver diseases before transplant, while 10 (3.05% cases were from 328 recipients with benign diseases. The incidence rates were comparable, p = 0.86. Furthermore, 2 cases developed in 1 year, 5 cases in 3 years and 11 cases over 3 years. The most frequent cancers developed after liver transplantation were similar to those in the general Chinese population but had much higher incidence rates. CONCLUSIONS: Liver transplant recipients were at increased risk for developing de novo cancers. The incidence rates and pattern of de novo cancers in Chinese population are different from Western people due to racial and social factors. Pre-transplant malignant condition had no relationship to de novo cancer. Exact risk factors need further studies.

    AIM: To describe the clinical and histological characteristics of a group of adults with small-bowel nodular lymphoid hyperplasia (NLH).METHODS: Patients were searched for five years in pathology records of our institution. The biopsy material was reassessed using strict histopathological criteria.Clinical data were obtained from medical records.RESULTS: Small-bowel NLH was diagnosed in 18 cases.The female: male ratio was 2: 1. The most frequent symptoms were diarrhea (72%), involuntary weight loss (72%) and abdominal pain (61%). Nine patients (50%)had immunodeficiency. Small-bowel bacterial overgrowth was found in three (17%) cases. At small-bowel NLH diagnosis, three (17%) had associated lymphoma: two intestinal and one extra-intestinal lymphomas. In two patients with villous atrophy and anti-endomysial antibodies the diagnosis of celiac disease was established.Giardia lamblia infection was found in only one patientwith hypogammaglobulinemia (Herman's syndrome).CONCLUSIONS; NLH is uncommon in adult patients.Associated diseases are immunodeficiency and lymphoid tissue malignancies.

    Background We characterized the incidence of central nervous system (CNS) involvement, risk factors and outcome in a large single institution dataset of peripheral T-cell lymphoma (PTCL). Methods Retrospective review of the PTCL database at Memorial Sloan Kettering Cancer Center. We identified 231 patients with any subtype of PTCL between 1994-2011 with a minimum six months of follow-up or an event defined as relapse or death. Results Histologies included peripheral T-cell lymphoma-not otherwise specified (PTCL-NOS) (31.6%), angioimmunoblastic (16.9%), anaplastic large cell lymphoma (ALCL), ALK- (12.1%), ALCL, ALK + (6.1%), extranodal NK/T-cell lymphoma (7.4%), adult T-cell leukemia/lymphoma (ATLL) (7.4%), and transformed mycosis fungoides (8.7%). Seventeen patients had CNS disease (7%). Fifteen had CNS involvement with PTCL and two had diffuse large B-cell lymphoma and glioblastoma. Median time to CNS involvement was 3.44 months (0.16-103.1). CNS prophylaxis was given to 24 patients (primarily intrathecal methotrexate). Rates of CNS involvement were not different in patients who received prophylaxis. Univariate analysis identified stage III-IV, bone marrow involvement, >1 extranodal site and ATLL as risk factors for CNS disease. On multivariate analysis, >1 extranodal site and international prognostic index (IPI) ≥ 3 were predictive for CNS involvement. The median survival of patients with CNS involvement was 2.63 months (0.10-75). Conclusions Despite high relapse rates, PTCL, except ATLL, carries a low risk of CNS involvement. Prognosis with CNS involvement is poor and risk factors include: >1 extra nodal site and IPI ≥3.

    Full Text Available The objective of this study was to assess the effect of hepatitis C virus (HCV infection on graft and patient survival in a cohort of Libyan renal transplant recipients. Medical records of 241 renal transplant (RT patients who have been followed-up at the Benghazi Nephrology Center up to February 2010 were reviewed. Based on the presence or absence of anti-HCV antibodies and HCV-RNA in the serum, patients were divided into two groups: HCV-positives and HCV-negatives. Anti-HCV antibodies were detected by the enzyme-linked immunosorbent assay technique and HCV-RNA by the polymerase chain reaction. Of the 241 RT patients, 162 were male and 79 were female. One hundred and ten patients (45.6% were HCV-positives and 131 (54.4% were HCV-negatives. Acute graft rejection was significantly higher among HCV-negative than HCV-positive patients (42 patients versus 28 patients, respectively; P < 0.001. Conversely, chronic graft rejection was higher among HCV-positives than that among HCV-negative patients (35 patients versus 24 patients, respectively; P <0.05, and this difference became more significant after a 12-month period of transplantation (P <0.01. Seventeen patients died during the follow-up: Seven HCV-positives (6.3% and 10 HCV-negatives (7.6%, and there was no significant difference in the death rate following RT between the two groups (P = 0.08. Among the seven deaths of HCV-positives, liver disease-related complications were the main cause of death in three (42.8% HCV-positive patients compared with none in the HCV-negative patients. The presence of HCV infection influenced chronic graft survival in RT patients and a higher proportion of HCV-infected patients had hepatic dysfunctions after RT. An increase in fatal liver complications was noted in HCV-positive patients with RT. In addition to pre-RT-specific therapy of HCV infection, all measures should be taken to prevent HCV infection pre- and post-RT. HCV-infected RT recipients need close monitoring for graft and liver function to prolong allograft and patient survival.

    Full Text Available Objective: To show etiology, diagnostic methods, and treatment options of patients with severe pericardial effusion determined after echocardiography. Methods: In this study, we retrospectively analyzed etiology, diagnosis and treatment options of 43 patients with severe pericardial effusions (i.e. effusions more than 20 mm either in front of the right ventricle or posterior to left ventricle as assessed by transthoracic echocardiography. The pericardiocentesis procedures were performed via subxiphoid approach. Glucose, protein, lactate dehydrogenase levels, polymerase chain reaction for tuberculosis, cytological, microbiological examinations and cultures were obtained from pericardial fluid. Results: Cardiac tamponade was diagnosed in 23 patients (54% and pericardiocentesis was immediately performed in these cases. Twenty patients who were unresponsive to empirical treatment, underwent pericardiocentesis to evaluate etiology and treatment.. Pericardial fluid was found to be exudate in 36 patients (83.7% and transudate in 7 patients (16.2%. The most common causes were malignancy (26%, and uremia (16% while idiopathic cases constituted 23% of the patient group. While malignant pericardial effusion was more common in males, idiopathic etiology and uremia were more common in female patients. Conclusion: Pericardiocentesis is the gold standard for clarifying the etiology and is also a lifesaving measure for cardiac tamponade. Delineating the specific etiology is particularly important for cases that do not respond to empirical treatment. A thorough history and physical examination, together with pericardiocentesis in selected cases will enable the accurate diagnosis of specific etiology and starting the treatment for this etiology.

    Conclusion: LS varies from being a highly aggressive disease of the penis and anterior urethra to a burnt out condition affecting just the meatus and surrounding glans. Early diagnosis and treatment are required to prevent its complication and associated morbidity. Management depends on the anatomical location of lesion, extent of involvement, rapidity of progression and its severity. Use of BMG in LS induced urethral stricture has shown encouraging results.

    Full Text Available Proper management of living kidney donors is a very important aspect of all renal transplants. To date, approximately 60,000 living donor nephrectomies have been performed worldwide and about 20 deaths directly related to the operation have been reported. The most common cause of death has been pulmonary embolism. Wound infection following surgery is the third most common nosocomial infection, and is dependent on the surgeon and his/her team, the operating room, number and virulence of contaminated bacteria, patient characteristics (immunity and defense, as well as time and duration of administration of antibiotics. Approach to the prophylaxis of wound infection in kidney donors varies in different transplant centers. This study was conducted at the Emam Hospital, Tabriz, Iran in order to delineate the protocol regarding antibiotic usage after donor nephrectomy. One hundred kidney donors were enrolled in the study. They were classified randomly in two groups: Group-1, comprising 50 donors, who received antibiotics immediately following surgery and for at least seven days thereafter. Group-2, comprised of 50 donors, in whom one gram of cephazoline was injected intravenously before anesthesia and continued for 24 hours after surgery. The patients were followed-up for one month with particular emphasis on occurrence of wound infection. One patient in Group-1, and two in Group-2 had wound infection; the difference was not statistically significant (p = > 0.5. Our study suggests that antibiotic prophylaxis started before incision and continued for 24 hours after donor nephrectomy is safe and effective in preventing wound infection.

    A decrease in live donor pediatric kidney transplants has occurred in the United States. This study investigates barriers that may influence access to live donor kidney transplants in children. Retrospective chart review was conducted for 91 children (69% male, mean age 11.9 years) who underwent pretransplant workup from 2005 to 2015 at an urban pediatric hospital. Fifty-four percent were African American, 32% Caucasian, 8% Arabic, 3% Hispanic, and 3% Others. Government-sponsored insurance (Medicaid/Medicare) was utilized by 73%, and 54% had dual caregivers. Only nine of 68 kidney transplants were live donor transplants. Live donor transplants (11%) were significantly (P=.008) lower than deceased donor transplants (59%) in African Americans. Private insurance was reported by 56% of live donor recipients and 25% of deceased donor recipients. Among live donor recipients, 78% were from dual caregiver families. Caregiver, health-related, financial, and religious/cultural barriers to live donor transplants were reported, several of which may be amenable to positive intervention.

    The purpose of this study was to investigate the effect of using antegrade selective cerebral perfusion (ASCP) with moderate hypothermia on hospital mortality after surgery for acute type A aortic dissection (AAAD). Between January 1998 and December 2008, 142 consecutive patients were operated on for AAAD. Patients were divided into two subgroups: the cohort of patients operated on from January 1998 until December 2003 (without ASCP) (P1998-2003, n=64) and the cohort operated on from January 2004 until December 2008 (with ASCP)(P2004-2008, n=78). The difference in hospital mortality was statistically significant (P1998-2003: 42.2%; P2004-2008: 14.1%, pperfusion with moderate hypothermia is a significant factor in decreasing hospital mortality.

    Poor graft function secondary to injury by ischemia and reperfusion remains a major problem with regard to morbidity and mortality in clinical liver transplantation (LTX). Up to one fifth of patients suffer from poor initial liver function due to severe damage to hepatocytes. This situation leads either to primary nonfunction described in approximately 6% of LTX or to slow recovery. We present a new method of reperfusion during LTX. From July 1998 to July 2002, 42 LTX in 39 recipients, (10 female, 52 years old (26-70) were performed. LTX was carried out in piggy-back technique. After completing the piggy-back anastomosis, the caval vein was declamped immediately, and retrograde low pressure reperfusion of the graft with low oxygenated venous blood was established. Portal anastomosis was performed using a running suture. In order to provide optimal retrograde liver perfusion, no clamping of the donor portal vein was done. After completing portal anastomosis, the recipient portal vein was declamped immediately. During arterial anastomosis, the transplanted liver was antegradely perfused via the portal vein. After completing hepatic artery anastomosis, declamping of the hepatic artery was done and arterial perfusion started. No backtable or in-situ-flushing except the described reperfusion technique was performed. Forty-two LTX in 39 recipients using piggy-back technique and retrograde reperfusion via the caval vein followed by antegrade reperfusion via the portal vein were performed; 38 out of 39 patients (97.44%) were alive and well at day 8 after LTX. One patient (2.56%) died of a pre-existing portal vein thrombosis on day 2 after LTX. Three patients had to undergo retransplantation for hepatic artery thrombosis (7.14%). Liver enzymes, bilirubine, prothrombine time and AT III on day 1, 3, 5 and 8 after LTX showed favourable values. Median aspartate aminotransferase (ASAT) was 219 U/l on day 1 after LTX. One-month survival rate was 95.23%, and 1-year survival rate 87.88%. Two patients died of liver-associated causes (5.12%). One patient died of a late hepatic artery thrombosis, and one more of rejection. No other severe case of rejection appeared. We can conclude that retrograde reperfusion might be highly sufficient method of removing perfusion fluid from the transplanted liver. Low pressure perfusion with low oxygenated blood might reduce the production of free oxygen radicals. Retrograde reperfusion via the caval vein and antegrade reperfusion via the portal vein seemed to lower postoperative liver enzyme values and to improve initial liver function after LTX.

    Our aim was to conduct a retrospective review to demonstrate the clinical, radiological, and electrophysiological features of patients with sporadic Creutzfeldt-Jacob disease (sCJD). A total of 10 patients (5 female and 5 male, with a mean age of 45 years from a range of 40 to 67 years) out of 8.259 adult patients hospitalized from January 2000 to December 2008 were diagnosed with sCJD. Eight of the patients were diagnosed on the basis of clinical, radiological, electroencephalography (EEG), and cerebrospinal fluid (CSF) findings. Two other patients also had a pathological diagnosis. The most common signs and symptoms were behavioral disturbances, movement disorders, cognitive decline, myoclonus, psychosis, focal neurological deficit, and aphasia. Nine of the patients had periodic sharp wave discharges on EEG. Seven patients were positive for the 14.3.3 protein in the CSF. Five patients had pulvinar signs-a bilateral increased signal in the pulvinar thalami-on cranial magnetic resonance imaging. Eight patients were diagnosed with probable sCJD; two were diagnosed with definite sCJD. All of the patients died as a result of the disease within 24 months after the onset of symptoms. sCJD should be considered in the diagnosis of patients who present with rapidly progressive dementia. Clinical and radiological data appear to be sufficient for the diagnosis. However, detailed molecular examinations of the subtypes of the disease may be required for early diagnosis of cases given the wide spectra of CJD.

    Full Text Available Mitral valve replacement (MVR with either a bioprosthetic or a mechanical valve is the treatment of choice for severe mitral stenosis. This study aimed to evaluate and compare the early and late outcome of mitral valve replacement (mechanical versus bioprosthetic for severe mitral stenosis. A retrospective cohort study was performed on prospectively collected data involving mitral stenosis patients who have undergone MVR with either bioprosthetic (BMV (n = 50 or mechanical (MMV (n = 145 valves in our institute from 1999 to 2012. Data were analyzed for early and late mortality, NYHA functional classes, stroke, early and late valve-related complications, and survival. Chi Square test, logistic regression, Kaplan Meier curve, and dependent proportions tests were performed. A total of 195 patients were included in the study with a follow-up of 190 patients (97.5%. One patient died early post-operatively; twelve patients died late in the post-operative period, BMV group (6 and the MMV (6. The Late mortality had significantly associated with post-op stroke (p < 0.001 and post-op NYHA classes III and IV (p = 0.002. Post-op NYHA class was significantly associated with age (p = 0.003, pulmonary disease (p = 0.02, mitral valve implant type (p = 0.01, and post-op stroke (p = 0.02; 14 patients had strokes in the MMV (9 and in the BMV (5 groups. NYHA classes were significantly better after the replacement surgeries (p < 0.001. Bioprosthetic valves were significantly associated with worse survival (p = 0.03, worse NYHA post-op (p = 0.01, and more re-operations (p = 0.006. Survival was significantly better with mechanical valves (p = 0.03. When the two groups were matched for age and mitral regurgitation, the analysis revealed that bioprosthetic valves were significantly associated with re-operations (p = 0.02 but not significantly associated with worse survival (p = 0.4 or worse NYHA (p = 0.4. Mechanical mitral valve replacement in mitral stenosis patients is associated with lower re-operation rate, but no difference in survival as compared to bioprosthetic mitral valve replacement. Furthermore, post-operative stroke occurrence (14% is associated with late mortality and worse NYHA classes.

    There are various clinical symptoms of thalassemia intermedia, and they lie roughly between those of major and minor forms of the disease. Patients with thalassemia intermedia occasionally require blood transfusions. This renders them susceptible to pulmonary arterial hypertension (PAH) syndrome, which is one of the most significant complications in patients with thalassemia intermedia. PAH is more common in in thalassemia intermedia than in thalassemia major, and it may cause cardiac complications in patients who are older than 30. The objective of this study was to estimate the prevalence of PAH in thalassemia intermedia patients so that they can be referred expeditiously for treatment, thereby preventing the complications that occur later. This cross sectional study was conducted under the supervision of hematology department of Mashhad Medical University. Forty-one patients with thalassemia intermedia were examined at the Sarvar Thalassemia and Hemophilia Clinic of Mashhad. Electrocardiography, chest radiography, and echocardiography tests were performed for all of the patients by the same pediatric cardiologist. The data were processed by SPSS software, version 11.5, and the results were analyzed using chi-squared, Student's t, and Mann-Whitney tests. The mean age of the patients was 21.93±8.34. They had been under pediatric heart specialists' constant examination and treatment since their childhood when they were diagnosed with TI, and continue to receive regular follow-up care. The prevalence of pulmonary hypertension was 24% in our study population. In patients with thalassemia intermedia, the left ventricular (LV) mass indices were about 3-5 times higher than would be expected in a normal population. Patients with higher LV mass indices have a greater risk of developing pulmonary hypertension, and those with serum ferritin levels below 1000 ng/ml are less susceptible to diastolic dysfunction. Pulmonary hypertension is common in patients with thalassemia intermedia. Irregular chelation therapy or absence of this treatment might lead to diastolic dysfunction, and serum ferritin levels below 1000 ng/ml could be an important factor in preventing the development of diastolic dysfunction or slowing down its progression.

    Background: The assessment of liver damage in various disease states relies on a combination of clinical findings, biochemical parameters and invasive tests such as liver biopsy. The ultrasound elastography has emerged as a potential alternative test, providing quantifiable information on the elasticity/stiffness of the examined-tissues. We assessed the performance of ultrasound elastography using real-time Acoustic Radiation Force Imaging (ARFI) technology in evaluating the degree of liver fibrosis in children with and without liver disease. Methods: Children aged 0-18 years, hospitalized in the Emergency Clinical County Hospital Tg. Mures, Romania, between September 15, 2010 and January 15, 2011, were eligible for the study. Four groups were recruited as follow: patients with liver disease in the setting of various malignant disorders, children with non-malignant liver disease, overweight and obese children and healthy controls. The liver tissue elasticity was assessed in each individual using Shear Wave Velocity (SWV). Biochemical tests included transaminase levels. 19 children with chronic liver disease underwent biopsies. SWV was measured globally and separately for the liver-segments 1 and 8. Correlations between the SWV and laboratory test were established using non-parametric Spearman correlation test. Results: A total of 103 children underwent liver ultrasound elastographic assessments. Of these, 39 had malignancies, 19 had various chronic liver diseases, 13 had nonalcoholic fatty liver disease (NAFLD), and 32 were healthy controls. The transaminase values differed significantly between children with liver diseases and controls. In normal controls SWV values in the 1st segment were significantly lower compared to those in the in 8th segment of the liver (p = 0.0216). In the group with hepatic steatosis, the SWV values were statistically higher compared to those in healthy controls. Positive statistical correlations have been established between AST and SWV in the group of children with NAFLD and those with malignancies (p = 0.0032, p = 0.0045). Conclusions: Quantification of liver fibrosis by ARFI method correlates with the histological fibrosis stage in children with chronic liver disease and NAFLD. Clinical applications of this method in the diagnosis of pediatric liver disease deserve further study.

    Full Text Available Chronic kidney disease (CKD is a worldwide public health problem and is associated with high morbidity and mortality. The majority of patients with CKD stage 5 (CKD-5, who cannot undergo renal transplant, depend on maintenance hemodialysis by surgically created access sites. Native fistulae are preferred over grafts due to their longevity. More than half of these vital portals for dialysis access will fail over time. Screening procedures to select high-risk patients before thrombosis or stenosis appears have resulted in aggressive management. These patients are referred for angiographic evaluation and/or therapy. We present the patterns of dialysis-related interventions done in our institution.

    Introducción: la supervivencia de los niños con tumores de la región pineal se ha incrementado en la última década; estos tienen una evolución insidiosa asociada con los desórdenes endocrinológicos y una alta morbilidad y mortalidad, sobre todo después de la resección. El objetivo es reportar la supervivencia, la morbilidad y mortalidad según el tipo de cirugía, la histología y el tratamiento en un grupo de niños con tumores de la región pineal. Métodos: estudio retrospectivo que incluyó a todos los pacientes con diagnóstico de tumor de la región pineal menores de 17 años de edad que acudieron en un periodo de 10 años a un hospital de pediatría. Se realizó una revisión histopatológica, se determinó la extensión de la resección y se estimó la supervivencia. Resultados: se incluyeron 46 pacientes, 36 de los cuales tenían expediente completo y material de patología adecuado. La resección total se realizó en 24 (66.6 %) y biopsia en 12 (33.3 %); fallecieron 23 pacientes (88 %) y fue el desequilibrio hidroelectrolítico la causa de 14 defunciones (60 %) y la progresión tumoral la causa de las 9 defunciones restantes (39.1 %). La sobrevida a 10 años de los pacientes tratados con resección total y biopsia fue del 52 y 75 %, respectivamente, con una p = 0.7; se presentaron alteraciones endocrinológicas en 13 (36.1%) pacientes de los cuales a 10 (76.9 %) se les realizó la resección de la tumoración. Conclusión: los tumores de la región pineal en niños se pueden tratar con biopsia diagnóstica seguida de tratamiento adyuvante con quimioterapia y radioterapia.

    The Cox maze procedure (CM) is safe and effective for all atrial fibrillation (AF) types. A recent randomized trial found alarming rates of pacemaker implantation (PMI) during hospitalization after CM. The purpose of this study was to assess the rate of PMI and its impact on outcomes after CM. Incidence of PMI was captured for all CM patients (2005-2015; N = 739). Data were collected prospectively. Multivariable logistic regression was conducted to determine risk factors for PMI. Propensity score matching was conducted between concomitant CM patients and patients without surgical ablation since 2011. Fifty-two patients (7.0%) had in-hospital PMI after CM. Most common primary indication for PMI was sick sinus syndrome (67%), followed by complete heart block (23%) and sinus bradycardia (10%). The only risk factor for in-hospital PMI was type of procedure (P = .020). Patients with multiple valve procedures were at greatest risk (P = .004-.035). STS-defined perioperative outcomes were similar for patients with and without in-hospital PMI. Sinus rhythm off antiarrhythmic drugs were similar by PMI. After propensity score matching (n = 180 per group), in-hospital PMI was similar in CM patients and those without surgical ablation (5% vs 4%, P = .609). This study demonstrated lower incidence of PMI after CM procedures than recently reported. When indicated, PMI was not associated with increased short- or long-term morbidity or inferior freedom from atrial arrhythmia. Efforts to increase surgeon training with the CM procedure and postoperative management awareness are warranted to improve rhythm outcome and minimize adverse events and PMI.

    New-onset diabetes after transplantation (NODAT) is a frequent metabolic complication and is considered a risk factor for patients undergoing renal transplant. The aim of this study was to evaluate the incidence and developing duration of new-onset diabetes after transplant (NODAT) and influencing factors. All patients' data was investigated retrospectively. Diabetics, follow-up period<6 months, age<18years were excluded. Demographic, clinical and laboratory data was recorded. Patients were divided into two groups: with/without NODAT. NODAT group was divided into four subgroups according to the time of developing NODAT, which were 0-3, 3-6, 6-12 and 12 months later. Two groups were compared, to investigate the incidence of NODAT and risk factors associated with the occurrence of NODAT. We retrospectively analyzed the records of 570 patients, of which 420 patients were included. Seventy (16.6%) patients had NODAT (36 female, mean age 51.7±8.2 years, mean follow-up 41.6±21.5 months), 52.8% of patients developed NODAT within the first three months of being diagnosed. 350 patients (116 female, mean age 43.2±12.5 years, mean follow-up 41.6±21.5 months) were without NODAT. The incidence of impaired fasting glucose (IFG) during the first week after transplant was found to be higher in the patients with NODAT (p<0.001). There was positive correlation between NODAT and older age, obesity, family history of diabetes, presence of IFG, fasting plasma glucose, total and LDL-cholesterol, triglycerides, parathormone. Old age, obesity, presence of IFG, pretransplant hypertriglyceridemia and hyperparathyroidism were predictors of development of NODAT. Incidence of NODAT, especially the first six months, was high. All patients should be screened for IFG within the first week. Patients with dyslipidemia, elderly and obese patients should be closely monitored for the risk of development of NODAT.

    Because acute pancreatitis (AP) associated with acute hepatitis E is rarely reported, we present such a case series. Records of patients admitted with AP to our institution between May 2007 and December 2013 were reviewed. Diagnosis of AP and acute hepatitis E was based on high serum amylase and/or lipase (>3 times the upper normal limit) and abdominal imaging and presence of serum IgM antibodies against hepatitis E virus, respectively. Other causes of AP were excluded by appropriate evaluation. Of 790 patients with AP, 16 (2.1%; median [range] age, 25 [16-54] years; 15 males) had hepatitis E and no other cause of AP; coexistent hepatitis A and B were present in two and one of them, respectively. Acute pancreatitis began (median [range], 8 [0-35] days) after acute hepatitis and was mild in 10 and severe in 6. Complications included intra-abdominal collections (5), acute renal failure (4), and acute lung injury (2). Median (range) bilirubin, alanine aminotransferase, and prothrombin time were 9.8 (0.4-25) mg/dL, 822 (54-4009) IU/L, 14.6 (9.7-27.4) seconds, respectively. Acute liver failure occurred in 1 patient only. No patient needed surgical, endoscopic, or percutaneous intervention. Acute pancreatitis associated with hepatitis E is not uncommon and usually has good prognosis.

    There is limited data on the etiology, clinical and histopathological spectrum and outcomes of crescentic glomerulonephritis (CrGN) in adult Indian population. This prospective study was done to evaluate the etiology, clinicohistological patterns and predictors of outcome of CrGN in South Indian population. All the patients received standard protocol based immunosuppression in addition to supportive care. Immune-complex glomerulonephritis (ICGN) was the most common etiology (n = 31; 77.5%) followed by pauci-immune glomerulonephritis (PauciGN; n = 8; 20%) and anti-glomerular basement membrane disease (n = 1; 2.5%). The most common etiology of ICGN was IgA nephropathy (n = 11; 27.5%) followed by lupus nephritis (n = 7; 17.5%) and post-infectious glomerulonephritis (PIGN) (n = 7; 17.5%). The patients with PauciGN were significantly older compared to those with ICGN (44.5 ± 15 years vs. 31.8 ± 11 years; P = 0.01). The patients with PauciGN presented with significantly higher serum creatinine (9.7 ± 4.4 vs. 6.6 ± 3.3 mg/dl; P = 0.03). The histopathologic parameters of ICGN and PauciGN were comparable except for a higher proportion of sclerosed glomeruli in ICGN. At the end of 3 months follow-up, only two patients went into complete remission (5.4%). Majority of the patients had end-stage renal failure (48.6%) and were dialysis dependent and seven patients (18.9%) expired. There was no signifi difference in the renal survival (10.9 ± 1.9 vs. 9.6 ± 3.3 months) or patient survival (17.5 ± 2.1 vs. 17.3 ± 4.3 months). The parameters associated with adverse outcomes at 3 months were hypertension (odds ratio [OR]: 0.58; confidence interval [CI]: 0.36-0.94), need for renal replacement therapy (OR: 0.19; CI: 0.04-0.9), serum creatinine at admission (P = 0.019), estimated glomerular filtration rate (P = 0.022) and percentage of fibrocellular crescents (P = 0.022).

Bracka two-stage repair is an attractive alternative surgical procedure with superior, reliable, and reproducible results. Purpose: To study the feasibility and applicability of Bracka two-stage repair for the severe proximal hypospadias and to analyze the outcomes and complications of this surgical technique. Materials and Methods: This prospective study was conducted from January 2011 to December 2013. Bracka two-stage repair was performed using inner preputial skin as a free graft in subjects with proximal hypospadias in whom severe degree of chordee and/or poor urethral plate was present. Only primary cases were included in this study. All subjects received three doses of intra-muscular testosterone 3 weeks apart before first stage. Second stage was performed 6 months after the first stage. Follow-up ranged from 6 months to 24 months. Results: A total of 43 patients operated for Bracka repair, out of which 30 patients completed two-stage repair. Mean age of the patients was 4 years and 8 months. We achieved 100% graft uptake and no revision was required. Three patients developed fistula, while two had metal stenosis. Glans dehiscence, urethral stricture and the residual chordee were not found during follow-up and satisfactory cosmetic results with good urinary stream were achieved in all cases. Conclusion: The Bracka two-stage repair is a safe and reliable approach in select patients in whom it is impractical to maintain the axial integrity of the urethral plate, and, therefore, a full circumference urethral reconstruction become necessary. This gives good results both in terms of restoration of normal function with minimal complication.

    The management of locally advanced pancreatic cancer (LAPC) is a major challenge. Although new drugs are available for the treatment of metastatic disease, the optimal treatment of non-metastatic cases remains controversial. The role of neoadjuvant therapy is still a question of debate in this setting. The aim of the study was to prospectively collect and analyse data on efficacy and safety of a modified FOLFIRINOX regimen in LAPC patients treated in a single institution. Another major objective was to assess the capability of FOLFIRINOX to render primary non-resectable cancer to resectable. No bolus fluorouracil was given and a 20% dose reduction of oxaliplatin and irinotecan was applied. Primary G-CSF prophylaxis was applied to prevent febrile neutropenia. Thirty-two patients (mean age 60.2 years, range: 40-77 years) have been enrolled into the study. All patients had ECOG performance status of 0 or 1. Best response to therapy was stable disease (SD) or partial regression (PR) in 18 (56.2%) and 6 (18.8%) cases. Two patients (6.3%) underwent surgical resection (100% R0). The most frequent grade 3/4 adverse events were nausea (18.8%), fatigue (12.5%) and diarrhea (12.5%). The incidence of severe neutropenia was 28.1%, with only one documented case of febrile neutropenia. The probability of disease progression was 25% and 50% after 75 and 160 days with 88.4% of possibility of disease progression after 500 days. OS probability was 92.1, 71.5% and 49.5% at 180-, 365 and 540 days. Our data does not support the capability of FOLFIRINOX to render primary non-resectable cancer to resectable. However, due to the high disease control rate observed, FOLFRINOX might be recommended as first line option for the palliative treatment of LAPC. Despite reduced chemotherapy doses significant toxicity has been seen.

    Gastrointestinal stromal tumor (GIST) is the most common mesenchymal neoplasm of the gastrointestinal tract. Surgery has been the only effective therapy. However, many patients still eventually die of disease recurrence. Chemotherapy and radiation therapy have been of limited value. Imatinib mesylate (Glivec) is an orally administered competitive inhibitor of tyrosine kinases associated with the KIT, ABL protein, licensed for the treatment of metastatic GIST since 2002 in Germany. We summarized the data of 16 patients with advanced or metastatic GIST treated with imatinib mesylate in palliative and neoadjuvant settings. Overall response was 81%, with no evidence of disease (NED) in 3/16 (19%), partial response (PR) in 9/16 (56%) and stable disease (SD) in 1/16 (6%), whereas 3/16 patients (19%) suffered from progressive disease (PD). Mean follow-up was 18.6 months [range: 4-30]. Mean progression-free survival (PFS) was 17.6 months [range: 0-30], mean overall survival (OS) from initial diagnosis was 32.3 months [range: 5-122]. Most common side effects were periorbital edema and skin rash. Imatinib mesylate is well tolerated in a dose of up to 800 mg/day and has significant activity during long- term treatment of patients with advanced or metastatic GIST. Copyright 2006 S.

    Background The results of total knee arthroplasty (TKA) in patients with inherited bleeding disorders (IBDs) are poorer when compared with those in the general population, with a notably higher risk of complications and higher revision rates. Thus, revision procedures are becoming a growing concern in this group of patients. The aim of this study was to evaluate the results of revision TKA in patients with IBD. Material/Methods A retrospective cohort study with longitudinal assessment of hemophilia patients scheduled for revision TKA between January 2010 and September 2015 was performed. The clinical status of the patients was assessed based on the Knee Society Score, and the Numeric Rating Scale was used to assess knee pain severity and patient satisfaction with the surgery. Radiological examination, post-operative complications, and reinterventions were recorded and analyzed. Results Very good results were obtained in all patients treated for aseptic loosening of the implant. However, inferior results were found in cases with infection. All patients operated on for aseptic loosening required only single-stage TKA, whereas patients with infection underwent multiple interventions. Complications were observed only in cases with infection. Conclusions Our study clearly outlined the differences in results based on failure mode, with far inferior results obtained in cases with infection. Given the lack of data in this area as well as the high specificity of this population, further high-quality studies are needed. PMID:28068306

    Renal biopsy is a gold standard for establishing diagnosis of acute rejection of the renal allograft. However, being invasive, renal biopsy has potential significant complications and contraindications. Therefore, possibility to noninvasively diagnose acute rejection would improve follow-up of kidney transplant patients. The purpose of this study was to evaluate urine immunocytology for T cells as a method for noninvasive identification of patients with acute renal allograft rejection in comparison to renal biopsy. In this prospective study a cohort of 56 kidney, or kidney-pancreas transplant recipients was included. Patients either received their transplant at the University Hospital "Merkur", or have been followed at the "Merkur" Hospital. Patients were subject to either protocol or indication kidney biopsy (a total of 70 biopsies), with simultaneous urine immunocytology (determination of CD3-positive cells in the urine sediment). Acute rejection was diagnosed in 24 biopsies. 23 episodes were T-cell mediated (6 grade IA, 5 grade IB, 1 grade IIA, 1 grade III and 10 borderline), while in 1 case acute humoral rejection was diagnosed. 46 biopsies did not demonstrate acute rejection. CD3-positive cells were found in 21% of cases with acute rejection and in 13% of cases without rejection (n.s.). A finding of CD3-positive cells in urine had a sensitivity of 21% and specificity of 87% for acute rejection (including borderline), with positive predictive value of 45% and negative predictive value of 68%. Although tubulitis is a hallmark of acute T cell-mediated rejection, detection of T cells in urine sediment was insufficiently sensitive and insufficiently specific for diagnosing acute rejection in our cohort of kidney transplant recipients.

    The shortage of deceased donors led to an increase of living donor kidney (LDK) transplantations performed in the presence of donor-specific antibodies (DSA) or ABO incompatibility (ABOi) using various desensitization protocols. We herein analyzed 26 ABOi and 8 Luminex positive DSA patients who were successfully desensitized by anti-CD20, antigen-specific immunoadsorption and/or plasmapheresis to receive an LDK transplant. Twenty LDK recipients with non-donor-specific HLA-antibodies (low risk) and 32 without anti-HLA antibodies (no risk) served as control groups. 1-year graft survival rate and renal function was similar in all 4 groups (creatinine: 1.63 ± 0.5 vs 1.78 ± 0.6 vs 1.64 ± 0.5 vs 1.6 ± 0.3 mg/dl in ABOi, DSA, low risk and no risk group). The incidence of acute T-cell mediated rejections did not differ between the 4 groups (15% vs 12, 5% vs 15% vs 22% in ABOi, DSA, low risk and no risk), while antibody-mediated rejections were only found in the DSA (25%) and ABOi (7.5%) groups. Incidence of BK nephropathy (BKVN) was significantly more frequent after desensitization as compared to controls (5/34 vs 0/52, p = 0.03). We demonstrate favorable short-term allograft outcome in LDK transplant recipients after desensitization. However, the desensitization was associated with an increased risk of BKVN.

    To evaluate the effect of temporary stent graft placement in the treatment of benign anastomotic biliary strictures. Nine patients, five women and four men, 22-64 years old (mean, 47.5 years), with chronic benign biliary anastomotic strictures, refractory to repeated balloon dilations, were treated by prolonged, temporary placement of stent-grafts. Four patients had strictures following a liver transplantation; three of them in bilio-enteric anastomoses and one in a choledocho-choledochostomy. Four of the other five patients had strictures at bilio-enteric anastomoses, which developed after complications following laparoscopic cholecystectomies and in one after a Whipple procedure for duodenal carcinoma. In eight patients, balloon-expandable stent-grafts were placed and one patient was treated by insertion of a self-expanding stent-graft. In the transplant group, treatment of patients with bilio-enteric anastomoses was unsuccessful (mean stent duration, 30 days). The patient treated for stenosis in the choledocho-choledochostomy responded well to consecutive self-expanding stent-graft placement (total placement duration, 112 days). All patients with bilio-enteric anastomoses in the non-transplant group were treated successfully with stent-grafts (mean placement duration, 37 days). Treatment of benign biliary strictures with temporary placement of stent-grafts has a positive effect, but is less successful in patients with strictures developed following a liver transplant.

    Various retinal manifestations can occur following a febrile illness due to viral, bacterial or protozoal etiology. As there are limited data in the literature, we undertook this study to analyse the clinical presentation of post-fever retinitis due to various etiologies, as well as its course and management. This was a retrospective study of 14 consecutive cases who presented to the Vitreo Retina Department of our hospital over a 1-year period between January 2010 and December 2010. All patients underwent detailed ophthalmic examination and relevant investigations including fundus fluorescein angiography and optical coherence tomography (OCT). Basic and specific investigations were performed as necessary. All patients were given systemic steroids which were tapered based on clinical response. Twenty-one eyes of 14 patients (7 bilateral, 7 unilateral) were studied. Onset of ocular symptoms was approximately 3 weeks after fever. Four patients had specific etiology-one each of chikungunya, enteric fever, malaria and abdominal abscess with pneumococcal pneumonia. The presenting visual acuity of the affected eyes averaged 2/60. Six eyes had relative afferent pupillary defect. All patients had solitary or multiple patches of retinitis at the posterior pole and exudation at the macula. OCT through the lesions revealed inner retinal hyperreflectivity and thickening with after-shadowing. All patients showed improvement in vision with unilateral cases improving to an average of 6/12 and bilateral cases improving to an average of 6/24. Patients also showed resolution of retinitis, macular edema and serous detachment. Post-fever retinitis as a condition manifested approximately 3 weeks after onset of fever. Irrespective of the cause of the fever, clinical presentation of cases was similar with inner retinitis at the posterior pole and a favourable response to steroids, suggesting a possible immunological basis for this condition.

    Background: There is little published literature on the profile of patients with Cushing's syndrome (CS) from India. The aim of this study was to compile data of CS patients treated at this hospital. Materials and Methods: Patients referred to the endocrine services of this hospital for diagnosis/treatment of CS from January 1985 to July 2012 were the subjects for this study. All patients had detailed medical history, physical examination and biochemical and hormonal assays (which changed with availability of tests and changing views). Assays for plasma adrenocorticotropic hormone (ACTH) (late 90s), salivary cortisol estimation, IJV sampling for ACTH and corticotrophin releasing hormone stimulation tests were added on later. Imaging included computed tomography (CT), magnetic resonance imaging (since the late 80's) and 68Ga DOTA-TOC/FDG PET-CT (2008). Results: Three hundred sixty-four patients (250 females, 114 males, age 6 months to 65 years, mean 28 years + 12 years) were diagnosed to have CS during this period. Two hundred and ninety-three patients (80.5%) were ACTH dependent (CD 215, ectopic ACTH syndrome 22, occult ACTH source 56) while 71 (19.5%) were ACTH independent (adrenal carcinoma 36, adenoma 30, primary pigmented nodular adrenal disease 4, AIMAH 1). Pituitary macro adenoma was seen in 14% of the CD cases. The most common presenting complaints were hypertension and diabetes mellitus. A total of 63% patients complained of weight gain while 15% had lost weight. Myopathy, infections, skeletal fractures and psychiatric problems were the other common observations in our patients. Conclusion: The clinical spectrum was broad. CD was the most common cause for CS. PMID:24701438

    A program for the prevention of major hemoglobinopathies was initiated in 2008 in the Kurdistan region of Iraq. This study reports on the achievements and challenges of the program. A total of 102,554 individuals (51,277 couples) visiting a premarital center between 2008 and 2012 were screened for carrier status of hemoglobinopathies, and at-risk couples were counseled. A total of 223 (4.3/1,000) couples were identified and counseled as high-risk couples. Available data on 198 high-risk couples indicated that 90.4% proceeded with their marriage plans, and 15% of these married couples decided to have prenatal diagnosis (PND) in subsequent pregnancies with the identification of 8 affected fetuses; all were terminated as chosen by the parents. Thirty affected births were recorded among the high-risk couples. The premarital program managed to reduce the affected birth rate of major hemoglobinopathies by 21.1%. Of the 136 affected babies born during the study period, 77.9% were born to couples married prior to the start of the program, while 22.1% were born to couples identified as having a high risk. The main reason for not taking the option of PND was unaffordable costs. Financial support would have increased opting for PND by high-risk couples. Further reduction in affected birth rates could be achieved by including parallel antenatal screening programs to cover those married before the initiation of the premarital program and improving the public health education and counseling programs. © 2015 S.

    Full Text Available Hemodialysis (HD is one of the important modalities of renal replacement therapy in acute renal failure (ARF as well as chronic renal failure (CRF. This study was performed to evaluate the various intradialytic complications that occur during HD and their management. This is a retrospective study performed in patients who underwent conventional HD during the period of 1 January 2000 to 31 December 2011 at our center. Clinical details, various complications faced and their management were retrieved from dialysis case sheets. A total of 2325 patients of renal failure (790 ARF and 1535 CRF patients were assessed for the intradialytic complications of HD. During the study period, there were 12,785 bicarbonate dialyses performed on these patients. In the ARF patients, the common intradialytic complications were: Hypotension, seen in 1296 sessions (30.4%, nausea and vomiting seen in 1125 sessions (26.4%, fever and chills seen in 818 sessions (19.2%, headache seen in 665 sessions (15.6%, cramps seen in 85 sessions (2.0%, chest pain and back pain seen in 82 sessions (1.92%, hypoglycemia seen in 77 sessions (1.8%, first-use syndrome seen in 72 sessions (1.7% and femoral hematoma seen in 31 sessions (0.73%. In the CRF group, common complications were hypotension in 2230 sessions (26.1%, nausea and vomiting in 1211 sessions (14.2%, fever and chills in 1228 sessions (14.4%, chest pain and back pain in 1108 cases (13.0%, hypertension in 886 sessions (10.4%, headache in 886 sessions (10.4%, cramps in 256 sessions (3.0%, hematoma in 55 sessions (0.64%, intracerebral hemorrhage in three sessions (0.03% and catheter tip migration in three sessions (0.03%. There is a need for special attention for the diagnosis and management of intradialytic complications of HD because such complications could be managed successfully without the need for termination of the dialysis procedure.

    Full Text Available Aim To evaluate frequency of CVD in dialysis population, in relationship to patients with and without diabetes, and their mostcommon treatment. Patients and methods This retrospective study included 187 patients, 106 males and 81 females, divided in two groups, diabetics and non-diabetics, treated by chronic hemodialysis. Patients’ analyses included: anamnesis, ECG, chest X rays, echocardiogram, laboratory examinations for calcium (Ca, phosphorus (P, parathormone (PTH, cholesterol (chol, triglicerids (TG, C-reactive protein (CRP, hemoglobin (Hb and uric acid. In addition, we analyzed groups of drugs used by patients as prescribed by cardiologists. Results Average age was 58.0 years, most of them between 51 and 60. Average hemodialysis length was 4 years. Primary kidney diseases were pyelonephritis and glomerulonephritis. 19,78% ofpatients had diabetes. 165 patients (88,23% had one or more cardiovascular diseases. 110 patients (58,2% had hypertension, mostof them used ACE inhibitors. Using test of multiple correlation,statistically signiicant correlations, among others, were shown between BMI and Ca, uric acid and P, albumin and PTH in diabetics, at the statistical signiicance level at p<0,05. Conclusion Cardiovascular diseases are the most common comorbidity and cause of mortality in hemodialysis population. There was no statistical signiicance in age, however there is a statistical difference in the dialysis duration variable, but in some biochemical laboratory parameters there was some difference. ACE inhibitors were most commonly used in the treatment of hypertension and systolic dysfunction, alone or with beta-blockers.

    Full Text Available Pregnancy-induced hypertension (PIH is a known complication of late pregnancy and is an important cause of maternal and fetal morbidity and mortality. Data on clinical profile, especially renal profile of preeclampsia and eclampsia in Indian women are lacking. The aim of our study was to examine the renal profile and clinical outcomes of patients diagnosed with PIH in our institution with a focus on the spectrum of acute kidney injury (AKI. In this prospective, observational study, 347 patients with a diagnosis of preeclampsia-eclampsia, who were undergoing treatment at the M. S. Ramaiah Medical College, were included in the study. The study duration was from 2010 to 2014. Details regarding epidemiologic data, obstetric data, laboratory parameters as well as maternal, renal, and fetal outcomes were noted. Patients with preexisting hypertension, diabetes mellitus, or chronic kidney disease were excluded from analysis. The overall incidence of preeclampsia was 3.4%. Hemolysis, elevated liver enzymes, and low platelets syndrome was seen in 31 patients (9%; 56 patients (19% had AKI with a mean serum creatinine of 3.2 mg/dL and mean proteinuria of 2.8 g/24 h. Nineteen patients required dialysis. Persistent renal failure was seen in 2.5% of the cohort. Maternal mortality was 2.5%, largely secondary to sepsis. Primiparity was a major risk factor. In this study, we found a low rate of preeclampsia in a low-to-moderate risk cohort, with an incidence of AKI and maternal mortality consistent with reported literature.

    Full Text Available There is limited data on the etiology, clinical and histopathological spectrum and outcomes of crescentic glomerulonephritis (CrGN in adult Indian population. This prospective study was done to evaluate the etiology, clinicohistological patterns and predictors of outcome of CrGN in South Indian population. All the patients received standard protocol based immunosuppression in addition to supportive care. Immune-complex glomerulonephritis (ICGN was the most common etiology (n = 31; 77.5% followed by pauci-immune glomerulonephritis (PauciGN; n = 8; 20% and anti-glomerular basement membrane disease (n = 1; 2.5%. The most common etiology of ICGN was IgA nephropathy (n = 11; 27.5% followed by lupus nephritis (n = 7; 17.5% and post-infectious glomerulonephritis (PIGN (n = 7; 17.5%. The patients with PauciGN were significantly older compared to those with ICGN (44.5 ± 15 years vs. 31.8 ± 11 years; P = 0.01. The patients with PauciGN presented with significantly higher serum creatinine (9.7 ± 4.4 vs. 6.6 ± 3.3 mg/dl; P = 0.03. The histopathologic parameters of ICGN and PauciGN were comparable except for a higher proportion of sclerosed glomeruli in ICGN. At the end of 3 months follow-up, only two patients went into complete remission (5.4%. Majority of the patients had end-stage renal failure (48.6% and were dialysis dependent and seven patients (18.9% expired. There was no signifi difference in the renal survival (10.9 ± 1.9 vs. 9.6 ± 3.3 months or patient survival (17.5 ± 2.1 vs. 17.3 ± 4.3 months. The parameters associated with adverse outcomes at 3 months were hypertension (odds ratio [OR]: 0.58; confidence interval [CI]: 0.36–0.94, need for renal replacement therapy (OR: 0.19; CI: 0.04–0.9, serum creatinine at admission (P = 0.019, estimated glomerular filtration rate (P = 0.022 and percentage of fibrocellular crescents (P = 0.022.

    Blood blister-like aneurysms (BBAs) are a controversial entity. They arise from non-branching sites on the supraclinoid internal carotid artery (ICA) and are suspected to originate from a dissection. Our aim is to describe the BBA cases seen in our center and to present a systematic review of the literature on BBAs. We analyzed the eleven cases of BBA admitted to our center from 2003 to 2012. We assessed the medical history, treatment modality (endovascular and/or surgery), complications and clinical outcome. The cohort included 8 women and 4 men with a mean age of 53.16 years. Treatment of the BBA consisted of stenting and coiling in 5 patients, stenting only in 4 patients, coiling and clipping in 1 patient, clipping only in 1 patient, and conservative treatment in 1 patient. A good outcome was found in 10 patients, as defined by a modified Rankin Scale (mRS) less than or equal to two at three months. A systematic review of the literature was performed, and 314 reported patients were found: 221 patients were treated with a primarily surgical approach, and 87 patients were treated with a primarily endovascular approach. A rescue or second treatment was required in 46 patients (21%). The overall estimated treatment morbidity rate was 17%, and the mortality rate was 15%. BBAs exhibit more aggressive behavior compared to saccular aneurysms, and more intra-operative complications occur with BBAs, independent of the treatment type offered. They are also significantly more likely to relapse and rebleed after treatment. Endovascular treatment offers a lower morbidity–mortality compared with surgical approaches. Multilayer flow-diverting stents appear to be a promising strategy.

    Twin anemia polycythemia sequence (TAPS) is defined by significant intertwin hemoglobin discordance without the amniotic fluid discordance that characterizes twin-twin-transfusion syndrome (TTTS) in monochorionic twin pregnancies. TAPS is an uncommon condition which can either occur spontaneously, or following fetoscopic laser ablation for TTTS. This complication is thought to result from chronic transfusion through very small placental anastomoses; however, the pathogenesis of TAPS remains unknown. Consequently, there is no consensus in the management of TAPS. In this article, three cases of TAPS are described and we review the literature on this uncommon pregnancy complication.

    Full Text Available Background: Primary hyperparathyroidism (PHPT has a variable clinical presentation and symptomatic PHPT is still the predominant form of the disease in India. Data from western India is lacking. Aim : To present the clinical profile of PHPT from western India. Settings and Design : This retrospective study was conducted at a tertiary care referral center. Materials and Methods : We analyzed the clinical presentation, biochemical, radiological features, and operative findings in adult patients with PHPT (1986-2008 and compared with our published data of children and adolescent patients with PHPT. Statistical Analysis : was done with SPSS 16 software. Results : Seventy-nine patients (F: M-2:1 with age ranging from 21 to 55 years (mean 33.5±8.82 were analyzed. Skeletal manifestations (75.5%, renal calculi (40.5% and proximal muscle weakness (45.5% were the most common symptoms of presentation with mean duration of symptoms being 33.70 (median: 24, range 1-120 months. Biochemical features included hypercalcemia (total corrected calcium 12.55±1.77 mg/dl, low inorganic phosphorus (1.81±0.682 mg/dl, elevated total alkaline phosphatase (mean: 762.2; median: 559; range: 50-4930IU/L and high parathyroid hormone (PTH (mean±SD: 866.61±799.15; median: 639.5; range: 52-3820 pg/ml. Preoperative localization was achieved in 74 patients and single adenoma was found during surgery in 72 patients. Hungry bone disease was seen in 30.3% and transient hypoparathyroidism developed in 62% patients. In comparison to PHPT in children there were no significant differences with regard to clinical, laboratory and radiological features. Conclusions : PHPT in western India is symptomatic disorder with skeletal and renal mani-festations at a much younger age. Clinical profile of PHPT in children is similar to that of adults.

    Full Text Available Renal transplantation is the treatment of choice for patients with end-stage renal disease. In Iraq, renal transplantation started in 1973 and has continued until now with live donor transplantation, since deceased donor transplant program is not approved as yet. Long-term transplant data are still scarce. The aim of our study is to present data on transplantation and medical follow-up at one year and, survival analysis at one, three and five years. A total of 250 renal transplantations were performed at the Nephrology and Renal Transplantation Center, Baghdad between January 2009 and January 2014. It is a living donor, blood group compatible donor program. All patients received triple immunosuppression (calcineurine inhibitor, mycophenolate mofetil or mycophenolic acid, and steroid. The Kaplan-Meier method was used to determine the survival rate. There were 92 live related donors, 143 unrelated donors, and 15 spouse donors. The mean age was 34.07 ± 12.2 years. The one-year graft survival for related and unrelated donor transplants was 98.9% and 91.8%, respectively. Graft survival was lower (82.9% in recipients with acute rejection episodes. The patient survival at one-year was 94%. The three-year graft and patient survival was 91% and 90%, respectively, and five-year survival for grafts and patients was 87.1% and 88%, respectively. The outcome of the renal transplantation in Iraq is improving. Long-term patient follow-up needs more meticulous attention. The development of renal transplant registry is critical for future planning. Moreover, renal transplantation practice in Iraq needs more social, religious, and governmental support.

    Full Text Available IgA nephropathy (IgAN is a common glomerular disease whose etiology is unknown. Previous studies have described the clinical and laboratory features but none have specifically compared patients during different time periods. This 20 year retrospective study was performed to assess trends in the severity of IgAN from 1989–2008. We reviewed 57 patient charts that contained a confirmed biopsy diagnosis of IgAN and recorded data at the time of diagnosis and the final follow-up appointment. Clinical data included physical examination, urine, and blood tests. Patients were separated into two cohorts, Cohort 1 1989–1998 and Cohort 2 1999–2008. An increase in severity was noted in Cohort 2 based on a significantly higher Up/c and lower serum albumin level. Other prognostic indicators including GFRe, hematocrit, and glomerular injury score also demonstrated a trend towards more severe disease over the past 20 years. The patients in both Cohorts received similar treatments and had comparable renal function at the last follow-up visit. Based on our findings, we suggest that although a kidney biopsy is required to diagnose IgAN, the procedure may not be necessary in patients clinically suspected of having the disease but who have normal kidney function and minimal urine abnormalities.

    Background The Medtronic InSync Sentry is the first available cardiac resynchronization therapy defibrillator (CRT-D)which can monitor fluid status by measuring intrathoracic impedance. This study was designed to observe the effectiveness of intrathoracic impedance monitoring on detecting aggravation of heart failure.Methods We retrospectively analyzed the clinical data of 14 consecutive patients. Patients were regularly followed up every 3-6 months after the implantation. At each visit, interrogation of the device was done. Patients were instructed to inform the researcher on hearing the device alert, and to take extra 40 milligrams of furosemidum if they had aggravated symptoms later. If the symptoms could not be relieved, they were asked to see a doctor. Data about heart failure hospitalization were collected from the medical record.Results During 18-48 months follow-up, a total of 7 patients encountered 28 alert events. On one hand, alert events appeared before all deteriorated symptoms and heart failure hospitalizations. On the other hand, there were 23 alerts followed by deterioration of heart failure symptoms, and 2 alerts related to 2 hospitalizations caused by pulmonary infection in one patient. Only 5 patients were hospitalized 10 times for deterioration of cardiac function.Conclusion The function of intrathoracic impedance monitoring is reliable in predicting deterioration of heart failure.

    Relapsing polychondritis (RP) is an autoimmune disorder characterized by inflammation in cartilaginous structures including the ears, noses, peripheral joints, and tracheobronchial tree. It rarely involves the central nervous system (CNS) but diagnosis of CNS complication of RP is challenging because it can present with varying clinical features. Herein we report 3 cases of relapsing polychondritis involving CNS with distinct manifestations and clinical courses. The first patient presented with rhombencephalitis resulting in brain edema and death. The second patient had acute cognitive dysfunction due to limbic encephalitis. He was treated with steroid pulse therapy and recovered without sequelae. The third patient suffered aseptic meningitis that presented as dementia, which was refractory to steroid and immune suppressive agents. We also reviewed literature on CNS complications of RP.

    Full Text Available Background: We sought to determine the clinical characteristics of pediatric esophagitis in southern Iran. Methods: This cross-sectional study was conducted over a 4-year period, from 2005 to 2009, in Nemazee Hospital, a tertiary healthcare center in Shiraz, southern Iran. We consecutively included all pediatric patients (<18 years who underwent endoscopy in our center and had pathology-confirmed diagnosis of esophagitis. Data regarding the patients’ demographic characteristics, comorbidities, and clinical findings were recorded using a questionnaire. All the patients underwent upper gastrointestinal endoscopy and biopsy of the esophagus, and the findings were recorded in the questionnaire. Results: We studied 125 children, comprising 61 (48.8% girls and 64 (51.2% boys at a mean age of 6.6±5.5 years. Repeated vomiting was the prominent symptom in our series, with it being reported by 75 (60% patients, followed by fever in 35 (28%. Erythema (33.6%, esophageal ulcer (11.2%, and whitish patch (8.0% were the most common endoscopic findings, while reflux esophagitis (32.8%, chronic (6.4% and acute esophagitis (5.6%, and candida esophagitis (5.6% were the most common histological diagnoses. Only one (0.8% patient was diagnosed as having eosinophilic esophagitis, aspergillosis, and graft-versus-host disease. Conclusion: Reflux was the most common cause of esophagitis in the pediatric population of southern Iran. Contrary to previous reports, the prevalence of eosinophilic esophagitis was far less than that estimated, while the prevalence of opportunistic infections was higher secondary to post-liver transplantation immunosuppression.

    The objective of this study was to assess the effect of hepatitis C virus (HCV) infection on graft and patient survival in a cohort of Libyan renal transplant recipients. Medical records of 241 renal transplant (RT) patients who have been followed-up at the Benghazi Nephrology Center up to February 2010 were reviewed. Based on the presence or absence of anti-HCV antibodies and HCV-RNA in the serum, patients were divided into two groups: HCV-positives and HCV-negatives. Anti-HCV antibodies were detected by the enzyme-linked immunosorbent assay technique and HCV-RNA by the polymerase chain reaction. Of the 241 RT patients, 162 were male and 79 were female. One hundred and ten patients (45.6%) were HCV-positives and 131 (54.4%) were HCV-negatives. Acute graft rejection was significantly higher among HCV-negative than HCV-positive patients (42 patients versus 28 patients, respectively; P<0.001). Conversely, chronic graft rejection was higher among HCV-positives than that among HCV-negative patients (35 patients versus 24 patients, respectively; P<0.05), and this difference became more significant after a 12-month period of transplantation (P<0.01). Seventeen patients died during the follow-up: Seven HCV-positives (6.3%) and 10 HCV-negatives (7.6%), and there was no significant difference in the death rate following RT between the two groups (P=0.08). Among the seven deaths of HCV-positives, liver disease-related complications were the main cause of death in three (42.8%) HCV-positive patients compared with none in the HCV-negative patients. The presence of HCV infection influenced chronic graft survival in RT patients and a higher proportion of HCV-infected patients had hepatic dysfunctions after RT. An increase in fatal liver complications was noted in HCV-positive patients with RT. In addition to pre-RT-specific therapy of HCV infection, all measures should be taken to prevent HCV infection pre- and post-RT. HCV-infected RT recipients need close monitoring for graft and liver function to prolong allograft and patient survival.

    Nonfluoroscopic mapping systems have demonstrated significant reduction of radiation exposure in radiofrequency (RF) catheter ablation procedures. However, their use as only imaging guide is still limited. To evaluate the usefulness of a completely nonfluoroscopic approach to catheter ablation of supraventricular arrhythmias using the Ensite-NavX™ electroanatomical navigation system. During 6 years, all consecutive patients referred for RF catheter ablation of regular supraventricular tachycardia (SVT) were admitted for a "zero-fluoroscopy" approach and studied prospectively. The only exclusion criterion was the need to perform a transseptal puncture. A total of 340 procedures were performed on 328 patients (179 men, age 55.7 ± 18.6 years). One hundred fifty-three patients had typical atrial flutter (AFL), 146 had AV nodal reentrant tachycardia (AVNRT), 35 had AV reciprocating tachycardia (AVRT), 4 patients had incisional atrial flutter (IAF), and 2 had focal atrial tachycardia (AT). Procedural success was achieved in 337 of the cases (99.1%). In 322 (94.7%), the procedure was completed without any fluoroscopy use. Mean procedure time was 110.5 ± 51.8 minutes. Mean RF application time was 9.8 ± 12.8 minutes and the number of RF lesions was 16.43 ± 15.8. Only 1 major complication related to vascular access was recorded. During follow-up, there were 12 recurrences (3.5%) (8 patients from the AVNRT group, 4 patients from the AP group). RF catheter ablation of SVT with an approach completely guided by the NavX system and without use of fluoroscopy is feasible, safe, and effective. © 2014 Wiley Periodicals, Inc.

    Kidney transplantation is the treatment of choice for end-stage renal disease (ESRD). Kidney transplantation recipients live longer and have better quality of life than patients on dialysis. Hypothalamic gonadal dysfunction in females who have ESRD may be reversed within the first few months after kidney transplantation, such as the ability to have children. Despite thousands of successful pregnancies in transplantation recipients, there is limited information about it. In this study, we evaluated the pregnancy rates and live birth rates in women (n = 133) who underwent kidney transplantation in our center from 1983 to 2010. Recipients of a second kidney transplantation and recipients of multiorgan transplantations were excluded. We observed 33 pregnancies with 11 live births (33.3%), 12 spontaneous abortions (36.36%), and 10 therapeutic abortions (30.3%). The pregnancy rate was 18%. The live birth rate was 33.3%. Therapeutic abortions were 36.3%, and the pregnancies resulting in fetal loss were 30.3%. The pregnancies were identified in 32 women. The majority of women (n = 32; 96.9%) had a single pregnancy, whereas 1 woman (3.1%) had two pregnancies. In our series, the pregnancy rates for kidney transplantation recipients were markedly lower and decreased more rapidly than those reported in the general population.

    The Wearable Cardioverter Defibrillator (WCD) is an external defibrillator that automatically detects and treats ventricular tachyarrhythmias without the need for assistance from a bystander while at the same time allowing the patient to ambulate freely. The main components of the system are the defibrillator unit and a chest belt with electrodes for arrhythmia detection and therapy delivery. Between December 1998 and October 2001, 84 patients used the device at our institution. The majority of patients had a history of acute myocardial infarction or coronary artery bypass surgery with an increased risk for sudden cardiac death or were awaiting heart transplantation. During a mean follow-up of 116+/-90 days, 7 episodes of ventricular tachyarrhythmias were detected and terminated successfully by the WCD in 5 patients. In 9720 days, there was one inappropriate shock due to oversensing of electrical noise. Four patients died during follow-up; none of them had a cardiac arrest while wearing the device. Five patients were excluded because of irregularities in device use. An ICD was implanted in 24 patients at the end of the follow-up period. The WCD is effective in detecting and treating ventricular tachyarrhythmias in patients with an intermittently increased risk for sudden cardiac death. Further use of the system in larger patient populations is needed to confirm its safety and cost effectiveness.

    Full Text Available Bioimpedance analysis has been widely used to estimate a hydration state, lean and fat mass in haemodialysis patients. The aim of our study was to investigate the validity and usefulness of bioimpedance analysis in routine dialysis practice. Last two years we used the body composition monitoring (BCM, Fresenius Medical Care, method based on whole body multifrequency bioimpedance spectroscopy (BIS, compared with traditional clinical data. For BIS data verification, hydration status of 32 stable HD patients with dialysis vintage more than 3 years and clinically well established dry weight were studied. Only in three cases BIS data seems underestimated in serial measurements. Next step, 28 healthy subjects and 116 dialysis patients were studied. Total body water and extracellular volume (ECV were significantly higher in dialysis group (P<0.01, and there was not any difference in intracellular volume (ICV. Mean AP was similar in patients with moderate (<15% and massive (>15% relative overhydration (RO = overhydration / ECV, at the same time, average number of antihypertensive medications was significantly higher in more overhydrated patients (3.1 vs 1.2. In clinical practice RO is more convenient indicator as compared to standard overhydration volume /dry weight ratio. Mutual application of the BIS and blood volume monitoring allows more rapid and safe dry weight achievement. BIS was useful tool for hydration status monitoring in routine haemodialysis practice, and further work need to be done to clarify BIS validity for nutritional status estimation.

    Full Text Available Background: There is little published literature on the profile of patients with Cushing′s syndrome (CS from India. The aim of this study was to compile data of CS patients treated at this hospital. Materials and Methods: Patients referred to the endocrine services of this hospital for diagnosis/treatment of CS from January 1985 to July 2012 were the subjects for this study. All patients had detailed medical history, physical examination and biochemical and hormonal assays (which changed with availability of tests and changing views. Assays for plasma adrenocorticotropic hormone (ACTH (late 90s, salivary cortisol estimation, IJV sampling for ACTH and corticotrophin releasing hormone stimulation tests were added on later. Imaging included computed tomography (CT, magnetic resonance imaging (since the late 80′s and 68 Ga DOTA-TOC/FDG PET-CT (2008. Results: Three hundred sixty-four patients (250 females, 114 males, age 6 months to 65 years, mean 28 years + 12 years were diagnosed to have CS during this period. Two hundred and ninety-three patients (80.5% were ACTH dependent (CD 215, ectopic ACTH syndrome 22, occult ACTH source 56 while 71 (19.5% were ACTH independent (adrenal carcinoma 36, adenoma 30, primary pigmented nodular adrenal disease 4, AIMAH 1. Pituitary macro adenoma was seen in 14% of the CD cases. The most common presenting complaints were hypertension and diabetes mellitus. A total of 63% patients complained of weight gain while 15% had lost weight. Myopathy, infections, skeletal fractures and psychiatric problems were the other common observations in our patients. Conclusion: The clinical spectrum was broad. CD was the most common cause for CS.

    Laparoscopic major hepatectomy is a common procedure that has been reported frequently; however, laparoscopic resection of centrally located tumors involving segments 4, 5, and 8 remains a technically difficult procedure because it requires 2 transection planes and dissection of numerous branches of the hepatic vein and glissonean capsule compared to hemi-hepatectomy. Here, we present 7 cases of totally laparoscopic right anterior sectionectomy (Lap-RAS) and 3 cases of totally laparoscopic central bisectionectomy (Lap-CBS).Between May 2013 and January 2015, 10 totally laparoscopic anatomical resections of centrally located tumors were performed in our institution. The median age of the patients was 54.2 (38-72) years and the median ICG-R15 was 10.4 (3.9-17.4). There were 8 patients with hepatocellular carcinoma (HCC) and 2 with metastatic colorectal cancer. All the HCC patients has the liver function impairment on the degree of Child-Pugh score A.The mean operation time was 330 ± 92.7 minutes with an estimated blood loss of 325 ± 234.5 mL. Only 1 patient required transfusion during surgery. Mean postoperative hospital stay was 9.5 ± 3.4 day and postop complication was reported only 1 case that has the fluid collection at the resection margin of the liver. Mean resection margin was 8.5 ± 6.1 mm and tumor size was 2.9 ± 1.9 cm.Totally lap-RAS and lap-CBS are feasible operative procedures in patients with centrally located tumor of the liver and particularly in patients with limited liver function such as those with cirrhosis.

  8. Three-port colectomy: reduced port laparoscopy for general surgeons. A single center experience.

    Le resezioni coliche laparoscopiche sia per patologie benigne che maligne sono state investigate da importanti RCT che ne hanno dimostrato la sovrapponibilità alla tecnica open convenzionale. La laparoscopia con un numero ridotto di trocar ha da quel momento trovato ampio sviluppo nell’ottica di massimizzare i benefici della mini-invasività. Proponiamo un’analisi dei nostri risultati nell’utilizzo della tecnica three-port nella emicolectomia sinistra attraverso un confronto con la classica resezione laparoscopica con quattro/ cinque accessi. Come è noto i laparoceli si sviluppano maggiormente su incisioni mediane mentre non vi è differenza tra lo sviluppo di questi dopo tecnica open o laparoscopica. Nell’ottica della chirurgia a numero ridotto di accessi, la tecnica single-port sembra dare vantaggi di minor traumatismo ma ciò a costo di aumentate difficoltà di esecuzione, aumento dei tempi operatori e dell’utilizzo di strumenti per lo più dedicati, con incisioni ombelicali che possono superare i 5 cm. Le resezioni coliche three port consentono di ridurre il numero di accessi e dunque delle complicanze a questi correlate con l’utilizzo di strumentazione standard e la possibilità di esecuzione su larga scala da parte di ogni chirurgo. L’analisi che abbiamo eseguito ha dimostrato nella nostra serie una riduzione dei tempi operatori nella tecnica three port e ciò può essere dovuto all’inserimento dei trocar addizionali ed al loro controllo ma soprattutto alla possibilità/ necessità del chirurgo esperto di essere meno influenzato da fattori quali una equipe non dedicata. Non sono stati evidenziati vantaggi nella riduzione della degenza operatoria. Il tasso di conversione è stato maggiore nella tecnica a ridotto numero di accessi, questo è possibile sia un bias legato alle conversioni precoci prima del posizionamento di restanti trocar in casi particolarmente complessi. In conclusione, la tecnica three port appare comparabile alla tradizionale laparoscopica, fornendo i vantaggi della riduzione del numero di accessi e delle complicanze a questi correlate.

    Keeping an updated registry of bleeding disorders is crucial for planning care and documenting prevalence. We aimed to assess the prevalence of various bleeding disorders including rare inherited coagulation and platelet disorders concerning their clinico-epidemiological, diagnostic data and bleeding manifestations severity. Patients suffering from manifestations of bleeding or coagulation disorders presented to Hematology Clinic during 16 years were included and prospectively followed up. Demographics, clinical characteristics, complete blood count, bleeding, prothrombin and activated partial thromboplastin times, platelet aggregation tests and bone marrow aspiration were recorded. Overall 687 patients with bleeding disorders from total 2949 patients were identified. Inherited coagulation defects were found in 27.2%; hemophilia A (70.6%), hemophilia B (13.9%), factor I deficiency (2.3%), factor V deficiency (1.6%), factor X deficiency (4.2%), factor VII deficiency (2.6%), factor XIII deficiency (1.1%), combined factor deficiency (2.1%) and unclassified coagulation disorders in 1.6% of studied patients. Overall 72.7% had diagnosed with platelet disorders; immune thrombocytopenia was the commonest (74.8%), and inherited conditions represent (25.2%) in the following order: Glanzman's thrombasthenia (11.2%), von Willebrand disease (6.6%), Bernard-Soulier syndrome (1%) and Chediak Higashi in 0.4% and unclassified in 6%. Median age of diagnosis of coagulation and platelet disorders were 33 and 72 months. Presenting symptoms of coagulation disorders were: 25.1% post circumcision bleeding, 22.5% ecchymosis, 20.9% hemoarthrosis and 15% epistaxis. Symptoms of rare coagulation disorders were postcircumcision bleeding (20%), bleeding umbilical stump (20%), epistaxis (12%), hemoarthrosis (8%) and hematomas (4%). Presenting symptoms in rare inherited platelet disorders were purpura, ecchymosis, epistaxis and bleeding gums, respectively. Analysis of the clinico-epidemiological data of patients with bleeding disorders is a useful tool for monitoring and improving their quality of care.

    Full Text Available Objective: To present and discuss the treatment of autoimmune hemolytic anemia (AIHA. Materials and Methods: The medical records of all patients (n=19 diagnosed in a tertiary hematology center between 1999 and 2010 were retrospectively reviewed.Results: Median age at diagnosis of AIHA was 5 years (range: 4 months-17 years. In all, 13 patients had primary (idiopathic AIHA, whereas 2 had primary Evans Syndrome (ES, 2 had autoimmune lymphoproliferative syndrome (ALPS+ES, and 1 had Wiskott-Aldrich syndrome (WAS+AIHA. Among the 13 primary idiopathic AIHA patients, 9 recovered following a 4-8-week course of prednisolone treatment without relapses, whereas 3 patients required a longer course of prednisolone. One AIHA patient that was very resistant to prednisolone recovered after cyclosporine A was added to the treatment. All patients with primary idiopathic AIHA were in remission for a median of 3 years (range: 4 months-10 years at the time this manuscript was written. Among the patients with primary ES, 2 had relapses similar to the ALPS patients. Splenectomy was performed in 1 primary ES patient, who at the time this report was written was also in remission. One ALPS patient required the addition of mycophenolate mofetil due to prednisolone resistance. The WAS patient was treatment resistant and died due to septicemia.Conclusions: Primary AIHA in pediatric patients generally has an acute onset and good response to corticosteroids. Primary or secondary ES has a chronic or relapsing course, and treatment may require other immunosuppressive agents in addition to corticosteroids. Complications of splenectomy must not be underestimated in patients with underlying immunodeficiency. AIHA often causes considerable morbidity and mortality in WAS.

    Background: Intraoperative neurophysiology, high magnification microscopes, and ultrasonic aspirators are considered essential aid for the safe resection of intramedullary spinal cord tumors (IMSCTs). Most centers in developing countries such as Pakistan still lack these facilities. The purpose of this study was to review the management of IMSCTs at our hospital and to determine factors associated with the outcomes of surgery. Methods: This was a retrospective review of medical records of adult patients undergoing surgery for IMSCT over 12 years. The institutional ethical review committee approved this study. Data were collected regarding demographics, clinical and radiological features, and surgical details. Modified McCormick Scale was used to grade patients’ neurological status at admission, discharge, and follow-up. Statistical analysis was performed using the Statistical Package for Social Sciences version 22. Results: Forty three cases were reviewed. Mean age was 33.8 ± 15.1 years whereas median follow-up was 5 months (range: 0.25–96 months). Most patients had ependymoma (n = 16; 73%). Cervical region was the most commonly involved (n = 15; 34.9%). Gross total resection (GTR) was achieved in 30 cases (69.8%). The preoperative McCormick grade was significantly associated with follow-up McCormick grade (P value = 0.002). Eight patients (18.6%) underwent intraoperative electrophysiological monitoring, out of which GTR was achieved in all cases, and none had disease progression or recurrence. Ten patients received postoperative radiotherapy. Thirty five patients (81.4%) had progression free survival at last follow-up. Conclusions: We achieved a GTR rate of 68.9% for IMSCTs with limited resources. In few cases, where intraoperative electrophysiology was used, the rate of GTR was 100%. Preoperative neurological status was associated with better postoperative McCormick score. PMID:27656322

    Snake bite is an important health hazard in tropical countries and is associated with significant morbidity and mortality. Herpes labialis is a common ailment caused by the Herpes simplex virus. There is no published data showing any association between the snake bite and development of Herpes labialis. Here, we present a series of patients who developed Herpes labialis after Russell's viper bite and had acute kidney injury. We attempted to find whether snake bite is an immunosuppressed state and whether it could have pre-disposed the patients to the development of these lesions.

    OBJECTIVE The goal of this paper was to investigate surgical and hardware complications in a longitudinal retrospective study. METHODS The authors of this registry study analyzed the surgical and hardware complications in 247 patients who underwent the implantation of a vagus nerve stimulation (VNS) device between 1990 and 2014. The mean follow-up time was 12 years. RESULTS In total, 497 procedures were performed for 247 primary VNS implantations. Complications related to surgery occurred in 8.6% of all implantation procedures that were performed. The respective rate for hardware complications was 3.7%. Surgical complications included postoperative hematoma in 1.9%, infection in 2.6%, vocal cord palsy in 1.4%, lower facial weakness in 0.2%, pain and sensory-related complications in 1.4%, aseptic reaction in 0.2%, cable discomfort in 0.2%, surgical cable break in 0.2%, oversized stimulator pocket in 0.2%, and battery displacement in 0.2% of patients. Hardware-related complications included lead fracture/malfunction in 3.0%, spontaneous VNS turn-on in 0.2%, and lead disconnection in 0.2% of patients. CONCLUSIONS VNS implantation is a relatively safe procedure, but it still involves certain risks. The most common complications are postoperative hematoma, infection, and vocal cord palsy. Although their occurrence rates are rather low at about 2%, these complications may cause major suffering and even be life threatening. To reduce complications, it is important to have a long-term perspective. The 25 years of follow-up of this study is of great strength considering that VNS can be a life-long treatment for many patients. Thus, it is important to include repeated surgeries such as battery and lead replacements, given that complications also may occur with these surgeries.

    Full Text Available We examined the effect of potential interfering factors that play major roles in the outcome of our patients with stomach cancer. 100 consecutive patients diagnosed with gastric cancers were prospectively observed, treated and followed from November 2009 to January. Absence of Helicobacter pylori infection (P=0.027, absence of vascularisation (P<0.001, and undetermined histopathological type of adenocarcinoma (P=0.003 were factors significantly associated with higher grade of gastric lesions. Life tables were used to define survival of gastric cancers. Survival rates of these patients at 1st week, 1st month, 2nd month, 3rd month, and 6th month were 97%, 96%, 91%, 90%, and 82%, respectively. The only determinant of 6 months of survival was age over 68 (P=0.039. Our study confirms our previous knowledge that gastric cancers have unfavorable outcome in Iran.

    Full Text Available Vietnam, in Asia, is a low middle-income country with a relatively large population to cater to. Not many know about Vietnam, or its healthcare sector especially the field of pediatric cardiology and congenital heart disease. In contrast to the developed world, congenital heart disease (CHD is not diagnosed early. Since most of the patients visit the hospital only in later stages of the disease there are many complications during the operation and post-operatively. But during the past 5 years (from 2009, there has been major improvement in the treatment of CHD, both by intervention and surgery. At present, all kinds of CHD, both simple and complex are being successfully treated in our country. Today in Vietnam, all children under 6 years of age have health insurance coverage, under which almost all operations and catheter interventions are done free in government hospitals. It is helping many patients, especially those from the poor socioeconomic background. However, the present infrastructure is inadequate and a long waiting list has accumulated for treatment of CHD.

    Full Text Available Renal transplantation (RTx has become the treatment of choice for end-stage renal disease (ESRD in autosomal dominant polycystic kidney disease (ADPKD, the most common genetic kidney disease. Because of the inheritable nature of this disease, live related donors might be avoided due to the fear of future appearance of polycystic disease. This retrospective singlecenter study was undertaken to evaluate patient/graft survival function vis-a-vis serum creatinine (SCr, rejection episodes and mortality in ADPKD vs matched control patients. Between 2000 and 2009, 18 (7.4% deceased donor renal transplant (DDRTx were performed for ESRD due to ADPKD. Diagnosis of ADPKD was established by family history and ultrasound. An individualized approach was applied for the need of pre-transplant nephrectomy. All recipients received rabbit-anti-thymocyte globulin induction and maintenance triple immunosuppression. Delayed graft function was observed in 33% patients, and 16% had biopsy-proven acute rejection. Over mean follow-up of 4.67 ± 2.2 years, patient and graft survival rates were 72.22% and 83.33%, with mean SCr (mg/dL of 1.44 ± 0.54, 1.78 ± 0.42 and 2.2 ± 0.6 at 1, 5 and 10 years. Overall, 44.4% (n-8 underwent pre-transplant nephrectomy. Infection and cardio/cerebrovascular events were the main causes of death. Patient, graft survival and acute rejection were similar between ADPKD and control group. DDRTx in ADPKD has acceptable patient and graft survival. Because of the inheritable nature of the disease, and unavailability of genetic linkage analysis as a routine, DDRTx is a viable option to avoid using unrelated donors.

    Objective. The goal of the study was to analyse the results of 85 cases of second-look laparotomy (SLL) and explore the influence of this procedure on survival. Patients and Methods. We reviewed retrospectively 85 cases of SLL collected and treated in our institute between 1994 and 2003. Results. Complete pathologic response (CPR) was 25.8%, microscopic disease (Rmicro) was 38.8%, and macroscopic disease (Rmacro) was 35.4%. In patients with negative SLL results, disease recurrence was diagnosed in 41%. The 3- and 5-year overall survival rates for the entire population were 91% and 87%, respectively. The 3- and 5-year disease-free survivals were, respectively, 76.3% and 58.5% in negative SLL versus 55.7% and 16% in positive SLL. The difference between the group of patients with complete response (76%) and the patients with residual microscopic disease (72%) was not significant. The tumoral residuum after initial surgery was the only prognostic factor influencing significantly the disease-free survival. On Cox regression model analysis, only initial tumoral residuum (P = 0.04) and tumoral residuum after SLL (P = 0.02) were independent prognostic factors for survival. Conclusions. The most important advantage of SLL is the early detection of recurrence and thus the early administration of consolidation treatment resulting in a better prognosis. PMID:23119177

    Highlights: • Periinterventional complications in 7.5% of patients with intracranial artery stenting. • 2.5% of periinterventional complications were perforator strokes. • 3.8% of patients developed a hemorrhagic stroke due to reperfusion injury. • Complications could be reduced by individualized measures to prevent perforator stroke or reperfusion injury. - Abstract: Background and purpose: Treatment of symptomatic intracranial atherosclerotic disease by angioplasty and stenting (PTAS) is limited by a high rate of periinterventional strokes. We performed a detailed analysis of these strokes at our center in order to identify strategies to reduce the risk of periinterventional complications. Methods: Case records and imaging data of 80 patients with a symptomatic 70–99% stenosis of a major intracranial artery treated with PTAS between July 2007 and December 2013 were reviewed. All patients had a sufficient response to aspirin and clopidogrel. Periinterventional strokes were categorized as either ischemic (perforator territory, distal embolic or delayed stent thrombosis) or hemorrhagic (intraparenchymal, subarachnoid). Results: Periinterventional complications occurred in 6/80 (7.5%) patients, consisting of 2 ischemic strokes (2.5%, both perforator territory), 3 hemorrhagic strokes (3.8%, 2 intraparenchymal due to reperfusion injury, 1 subarachnoid due to vessel rupture) and one death (1.3%) unrelated to stroke. All strokes occurred within 24 h after PTAS. Conclusion: Our retrospective data analysis suggests that the risk of periinterventional stroke after PTAS of symptomatic intracranial atherosclerotic disease might be reduced by sufficient antiplatelet therapy and optimized management of patients with high risk for reperfusion injury or perforator strokes, including selection of a stenting device adapted to individual vessel morphology.

    Information about extrapulmonary small cell carcinoma (EPSCC) is limited and the role of prophylactic cranial irradiation (PCI) is unknown. Disease presentation and outcome of all EPSCC at our hospital between 1990 and 2009 were retrospectively analyzed. Of 30 EPSCC, the male:female ratio was 58%:42%; 83% had a performance status of 0-2. Median age was 71 years (32-80). Seventeen (57%) had limited stage (LS), 13 (43%) extensive stage (ES). The location of the primary tumor was gastrointestinal (n = 8), unknown (6), gynecological (6), urogenital (5), and ear nose throat (5). Four (13%) developed brain metastases (2 ES, 2 LS). In ES, first line chemotherapy (CT) was given in 85%, mostly platinum-etoposide (64%). Response rate was 90%. In LS, CT and radiotherapy (RT) {+-} resection resulted in persistent remissions in 67% of patients. Median survival was 16 months (1-107 months), 18 months (1-107 months), and 9 months (0.4-25 months) for LS + ES, LS, and ES, respectively. Weight loss {>=}5 % and ECOG performance status 3 + 4 were associated with poorer survival (p < 0.001 and p < 0.01, respectively). The incidence of brain metastases was relatively low (13%). More studies are necessary, before routinely offering PCI to patients with EPSCC. Best survival outcomes in LS were achieved with multimodality treatment including CT and RT. Prognosis was poor in patients with ES. (orig.)

    Full Text Available Acute renal failure following vasculotoxic viperine snake bites is very common in South Asia. Acute tubular necrosis and acute cortical necrosis are the common findings, with acute interstitial nephritis (AIN being a rare presentation. We conducted renal biopsies in all patients who were admitted in our institute with viperine snake bite-related acute kidney injury (AKI and who did not improve after three weeks of supportive care. Patients who had findings of AIN on renal histology were included for this study. Of a total of 42 patients, there were five patients (11.9% with AIN. Our series of five patients is the largest series of this rare presentation in the literature. All of these five patients had features of severe envenomation, severe AKI network stage of AKI and very high antivenom requirements. They had a very prolonged stay in the hospital, and four of the five patients developed chronic kidney disease on follow-up. The overall outcome in this group was worse as compared with those who did not have AIN. AIN following viperine snake bites is not a very rare presentation. The reason for the development of this pathology is unclear, but direct venom-related effects are possible. This presentation portends a poor overall long-term prognosis as demonstrated in our case series.

    In this study, we retrospectively examined the data of children who underwent allo-HSCT from HLA-matched family donors. We analyzed the incidence, etiological factors, clinical characteristics, possible reasons, risk factors, and follow-up of neurologic complications. BU-based conditioning regimens were used in most of the cases (n = 62). The median duration of follow-up for the 89 patients was 20 months (range 1-41 months). Eleven percent of transplanted children developed one or more neurological symptoms after HSCT with a median observation time of two months (range -6 days to 18 months). The median age of the four girls and six boys with neurological complication was 13 yr (range 5.3-17.6 yr). Cylosporine A neurotoxicity was diagnosed in five children, four of them were PRES. The rest of complications were BU and lorazepam toxicity, an intracranial hemorrhage, a sinovenous thrombosis, and a transient ischemic attack during extracorpereal photopheresis. No difference was found between groups of neurological complication according to age, gender, diagnosis, hospitalization time, neutrophil and platelet engraftment time, stem cell source, and conditioning regimen, acute and chronic GVHD or VOD. Neurological complication was the cause of death in one patient (1.1%).

We analyze a series of Brazilian patients with HNPP. Correlations between clinical manifestations, laboratory features, electrophysiological analyze, histological and molecular findings were done. In five cases, more than one episode occurred before diagnosis. Median nerve in the carpal tunnel at the wrist, ulnar nerve in its groove at the elbow, fibular nerve in the head of the fibula at the knee, radial nerve in its groove of the humerus and suprascapular nerve in its notch at the supraspinous fossa were found as focal neuropathies. One patient presented with persistent writer’s cramp after ulnar nerve palsy. Nerve conduction studies showed focal neuropathy in all patients and concomitant generalized symmetrical neuropathy in eight patients. Molecular analysis of the PMP22 gene detected deletion of the 1.5-Mb fragment in all patients.

    BACKGROUND: Acute hepatic failure (AHF) is a devastating clinical syndrome with a high mortality rate. The outcome of AHF varies with etiology, but liver transplantation (LT) can significantly improve the prognosis and survival rate of such patients. This study aimed to detect the role of LT and artificial liver support systems (ALSS) for AHF patients and to analyze the etiology and outcome of patients with this disease. METHODS: A retrospective analysis was made of 48 consecutive patients with AHF who fulfilled the Kings College Criteria for LT at our center. We analyzed and compared the etiology, outcome, prognosis, and survival rates of patients between the transplantation (LT) group and the non-transplantation (N-LT) group. RESULTS: AHF was due to viral hepatitis in 25 patients (52.1%; hepatitis B virus in 22), drug or toxic reactions in 14 (29.2%; acetaminophen in 6), Wilson disease in 4 (8.3%), unknown reasons in 3 (6.3%), and miscellaneous conditions in 2 (4.2%). In the LT group, 36 patients (7 underwent living donor LT, and 29 cadaveric LT) had an average model for end-stage liver disease score (MELD) of 35.7. Twenty-eight patients survived with good graft function after a follow-up of 27.3± 4.5 months. During the waiting time, 6 patients were treated with ALSS and 2 of them died during hospitalization. The 30-day, 12-month, and 18-month survival rates were 77.8%, 72.2%, and 66.7%, respectively. In the N-LT group, 12 patients had an average MELD score of 34.5. Four patients were treated with ALSS and all died during hospitalization. The 90-day and 1-year survival rates were only 16.7% and 8.3%, respectively. CONCLUSIONS: Hepatitis is the most prominent cause of AHF at our center. Most patients with AHF, who fulfill the Kings College Criteria for LT, did not survive longer without LT. ALSS did not improve the prognosis of AHF patients, but may extend the waiting time for a donor. Currently, LT is still the most effective way to improve the prognosis of AHF patients.

    Full Text Available Prospective studies concerning liver disease in pediatric cystic fibrosis patients are scarce. The present study aimed to describe the prevalence and clinical expression of cystic fibrosis - related liver disease, in a cohort of 62 pediatric patients. Descriptive study, resulting from the prospective evaluation, between 1994 and 2009, of 62 pediatric patients (age <18 years with cystic fibrosis. The follow-up protocol included a clinical assessment every 2 months, liver function tests every 6 months and annual liver ultrasonography. The cumulative prevalence of liver disease was 11.2% (7/62 cases. All patients had ΔF508 mutation and pancreatic insufficiency, none had meconium ileus. The liver involvement became clinically evident at a mean age of 8 years (3-15 years, revealed by hepatomegaly or hepatosplenomegaly (3 cases and/ or abnormalities of liver function tests (3 cases changes of liver ultrasound (7 cases with evidence of portal hypertension (2 cases. Four patients were submitted to liver biopsy; biliary fibrosis was documented in one case, focal biliary cirrhosis in 2 cases and multilobular cirrhosis in another case. Within a median 11.6 years follow-up period (all patients under UDCA therapy after liver disease diagnosis, progression of liver disease was observed in 2 patients; one patient developed refractory variceal bleeding and progressive hepatic failure, requiring liver transplant. The results of the present study agree with those of previous pediatric studies, further documenting clinical expression of liver disease in CF patients, which is usually detected in the first decade of life and emphasize the contribution of ultrasound to early diagnosis of liver involvement. Moreover, although advanced liver disease is a relatively rare event, early isolated liver transplantation may have to be considered at this age group.

    AIM: To evaluate survival rate and clinical outcome of cholangiocarcinoma. METHODS: The medical records of 34 patients with cholangiocarcinoma, seen at a single hospital between the years 1999-2006, were retrospectively reviewed. RESULTS: Thirty-four patients with a median age of 75 years were included. Seventeen (50%) had painless jaundice at presentation. Sixteen (47.1%) were perihilar, 15 (44.1%) extrahepatic and three (8.8%) intrahepatic. Endoscopic retrograde cholangiography (ERCP) and/or magnetic resonance cholangiography (MRCP) were used for the diagnosis. Pathologic confirmation was obtained in seven and positive cytological examination in three. Thirteen patients had co-morbidities (38.2%). Four cases were managed with complete surgical resection. All the rest of the cases (30) were characterized as non-resectable due to advanced stage of the disease. Palliative biliary drainage was performed in 26/30 (86.6%). The mean follow-up was 32 mo (95% CI, 20-43 mo). Overall median survival was 8.7 mo (95% CI, 2-16 mo). The probability of 1-year, 2-year and 3-year survival was 46%, 20% and 7%, respectively. The survival was slightly longer in patients who underwent resection compared to those who did not, but this difference failed to reach statistical significance. Patients who underwent biliary drainage had an advantage in survival compared to those who did not (probability of survival 53% vs 0% at 1 year, respectively, P = 0.038). CONCLUSION: Patients with cholangiocarcinoma were usually elderly with co-morbidities and/or advanced disease at presentation. Even though a slight amelioration in survival with palliative biliary drainage was observed, patients had dismal outcome without resection of the tumor.

    Full Text Available Waldenström′s Macroglobulinemia (WM is a B cell neoplasm characterized by infiltration of the bone marrow by a lymphoplasmacytic infiltrate and an IgM monoclonal gammopathy. We report a 15-year review of patients diagnosed with WM at our center. A total of 18 patients were diagnosed and treated at our center during the study period. Neurological symptoms were seen in almost 95% while B symptoms were present in almost 80% of patients. More than two-thirds of patients were anemic at the time of presentation and more than 90% showed bone marrow infiltration with lymphoplasmacytoid cells. Anemia, B symptoms, splenomegaly and neurological symptoms were the primary reasons in the majority of patients to initiate treatment. Chlorambucil was the primary treatment in more than half the patients followed by CVP. The median overall survival in all patients was 29 months (range 22-81 months. WM is a rare disorder and novel therapeutic modalities need to be identified to improve survival in these patients.

    Objective. The objective of this study was to determine the frequency of pulmonary arterial hypertension (PAH) in congenital heart disease (CHD) with an isolated, large left-to-right shunt and to indicate the factors in the development of PAH. Methods. The pressure measurements in the cardiac chambers and the calculations based on the Fick's principle were compared among 3 separate groups of patients, respectively, with PAH, with hyperkinetic pulmonary hypertension (HPH), and with neither PAH nor HPH. Results. PAH was diagnosed in 30 (12.3%) patients, HPH in 35 (14.4%), while 177 (73.1%) were free of either. The highest risk for the development of PAH was found in the presence of perimembranous ventricular septal defect. A statistically significant difference was seen among these groups as to their left atrial pressure (p = 0.005) and the mean pulmonary arterial pressure (PAPmean; p < 0.001). While a correlation was present between RpI on one hand and age on the other (p = 0.014), a multiple linear regression could not evidence any correlation among age (p = 0.321), gender (p = 0.929). Conclusion. Our findings do not allow establishing a correlation between the duration of the high pulmonary flow and pulmonary vascular resistance increase or PAH development in isolated left-to-right shunts with congenital heart diseases.

    题目:高压球囊扩张治疗男性前尿道狭窄:单中心的临床经验  目的:评估高压球囊扩张治疗男性前尿道狭窄的有效性和安全性。  创新点:既往高压球囊扩张技术已成熟应用于输尿管狭窄的临床治疗,我们将这一技术拓宽应用于男性前尿道狭窄的治疗,并证明高压球囊扩张治疗前尿道狭窄同样安全、有效。  方法:采用回顾性病例对照研究,收集并分析了31例接受高压球囊扩张和25例接受直视下尿道内切开术治疗的前尿道患者的病例资料,比较两组患者的手术时间、手术难易程度、术后并发症(出血和感染)、术后1年狭窄复发率和术后3年狭窄复发率等相关指标。  结论:高压球囊扩张组的手术时间和术后并发症发生率要优于直视下尿道内切开术组,两组患者的远期尿道狭窄复发率无统计学差异,但高压球囊扩张组的术后1年狭窄复发率明显低于直视下尿道内切开术组。高压球囊扩张治疗男性前尿道狭窄是安全、有效的,且近期疗效要优于传统腔内治疗方式。%Objectives: We retrospectively reviewed the urethral stricture cases treated in our tertiary center, and assessed the safety and feasibility of the high-pressure baloon dilation (HPBD) technique for anterior urethral stricture. Methods: From January 2009 to December 2012, a total of 31 patients with anterior urethral strictures underwent HPBD at our center, while another 25 cases were treated by direct vision internal urethrotomy (DVIU). Patient de-mographics, stricture characteristics, surgical techniques, and operative outcomes were assessed and compared between the two groups. The Kaplan-Meier survival analysis was applied to evaluate the stricture-free rate for the two surgical techniques. Results: The operation time was much shorter for the HPBD procedure than for the DVIU ((13.19±2.68) min vs. (18.44±3.29) min,P<0.01). For the HPBD group, the major postoperative complications as urethral bleeding and urinary tract infection (UTI) were less frequently encountered than those in DVIU (urethral bleeding: 2/31 vs. 8/25,P=0.017; UTI: 1/31 vs. 6/25P=0.037). The Kaplan-Meier survival analysis showed that there was no significant difference in stricture-free rate at 36 months between the two groups (P=0.21, hazard ratio (HR)=0.65, 95% confidence interval (CI): 0.34 to 1.26). However, there was a significantly higher stricture-free survival in the HPBD group at 12 months (P=0.02, HR=0.35, 95% CI: 0.14 to 0.87), which indicated that the stricture recurrence could be delayed by using the HPBD technique. Conclusions: HPBD was effective and safe and it could be considered as an alternative treatment modality for anterior urethral stricture disease.

    patients during a 9-year period. RESULTS: A total of 292 ERCPs were included. Overall post-ERCP complications occurred in 24 procedures (8.2%): pancreatitis in 8 (2.7%), bleeding in 5 (1.7%), and cholangitis in 13 (4.5%) procedures. Simultaneous pancreatitis and cholangitis, and simultaneous bleeding...... and cholangitis occurred after two procedures, respectively. Multivariate analysis concerning overall complications identified biliary sphincterotomy (p = 0.006) and time since liver transplantation within 90 days postoperatively (p = 0.044) as risk factors for post-ERCP complications. Specifically concerning...... post-ERCP pancreatitis (PEP), it was found that pre-ERCP cholangitis was another independent risk factor for PEP (p = 0.026). Stent in the biliary tract prior to ERCP seemed to be protective (p = 0.041). CONCLUSIONS: Complications were of surprisingly mild degree. The rates of post-ERCP complications...

    The aim of our retrospective study is to analyze surgical possibilities for the extended LABC in those cases not suitable for a neoadjuvant chemotherapy step and to consider various reconstruction techniques. Between 2009 and 2015 we enrolled 11 patients, admitted to the Emergency Department, presenting ulcerated LABC that needed palliative surgical demolitive procedures because of bleeding and anemia and in which was necessary to use natural tissues transposition or synthetic substitutes for the reconstruction of the skin flaps. The mean follow up was 12 months. Mortality rate was 82% (9 patients); in 2 cases there was local relapse after 6 months; 9 months was the longest disease free survival. Thanks to multidisciplinary strategies LABC's surgical treatment improved results with a five-year survival rate between 30-40% and better quality of survival. Despite extended demolitive approach, there is still a 50% of death because of metastases. Our results confirm that musculocutaneous flap, skin anterior thigh grafts, bilayer matrix wound dressing are excellent reconstructive strategies in locally advanced ulcerated breast cancer after aggressive extended surgery even if palliative to improve patients' further survival. Our data also showed that those patients presenting medium level of malignancy as "luminal b" subtype (7 patients) if treated earlier with a radical surgical procedure would have better prognosis.

    LT has emerged as a surgical treatment for UCDs. We hypothesize that LT can be safely and broadly utilized in the pediatric population to effectively prevent hyperammonemic crises and potentially improve neurocognitive outcomes. To determine the long-term outcomes of LT for UCDs, charts of children with UCD who underwent LT were retrospectively reviewed at an academic institution between July 2001 and May 2012. A total of 23 patients with UCD underwent LT at a mean age of 3.4 yr. Fifteen (65%) patients received a whole-liver graft, seven patients (30%) received a reduced-size graft, and one patient received a living donor graft. Mean five-yr patient survival was 100%, and allograft survival was 96%. Mean peak blood ammonia (NH(3) ) at presentation was 772 μmol/L (median 500, range 178-2969, normal <30-50). After transplantation, there were no episodes of hyperammonemia. Eleven patients were diagnosed with some degree of developmental delay before transplantation, which remained stable or improved after transplantation. Patients without developmental delay before transplantation maintained their cognitive abilities at long-term follow-up. LT was associated with the eradication of hyperammonemia, removal of dietary restrictions, and potentially improved neurocognitive development. Long-term follow-up is underway to evaluate whether LT at an early age (<1 yr) will attain improved neurodevelopmental outcomes.

    Full Text Available OBJECTIVE: To investigate the secondary progressive multiple sclerosis (SPMS patients treated with mitoxantrone (MIT and discuss the effectiveness and side effects of MIT. METHODS: We retrospectively investigated 48 SPMS patients who completed or were still receiving MIT treatment. Expanded Disability Status Scale (EDSS scores of the patients were determined who had detailed examination before the treatment. Complete blood count, urine examination, chest x-ray, kidney and liver function tests, transthoracic echocardiography were performed at initiation and during follow-up and 10 mg/m2 MIT was administered every three months. The data were assessed in order to determine the effectiveness and side effects. RESULTS: A total of 48 patients, 34 women and 14 men, had an age of 42 (26-55 years at the initiation of MIT treatment. The duration of the treatment was 12 (3-30 months. The median EDSS scores were 6 (4-8 before the treatment and 6 (4-9 after the treatment. EDSS scores improved in 6 patients, deteriorated in 12 patients and 30 patients remained with stable EDSS scores during the treatment. Seventeen patients had no side effects however 31 patients developed side effects. CONCLUSION: On the basis of this study, which is a clinical assessment of the effectiveness and side effects of MIT, we conclude that MIT can limit disability in SPMS patients and it is useful in treating SPMS patients due to favorable risk-benefit ratio.

    Full Text Available Hematopoietic stem cell transplant (HSCT is a life-saving procedure for patients with several malignant and nonmalignant hematological disorders. Acute kidney injury (AKI is a common complication after HSCT. The aim of the study was to identify the incidence and outcomes of AKI associated with HSCT in our center. Sixty-six HSCT recipients from October 2008 to March 2014 at Christian Medical College, Ludhiana, were followed up till July 31, 2014. RIFLE criteria utilizing serum creatinine was used to diagnose and stage AKI. Mortality and AKI were the primary outcomes studied. The risk of AKI in relation to conditioning regimen, type of HSCT (allogeneic and autologous, co-morbidities, graft versus host disease, drug toxicity, and veno-occlusive disease were analyzed. Sixty-five patients were included in the study. Male: Female ratio was 3.6:1 with a median age of 17 years (1.5–62. Forty-nine (75.4% patients had AKI over 3 months, R 17 (26.2%, I 19 (29.2%, and F 13 (20%. AKI occurred at a mean of 19.4 ± 29.2 days after the HSCT. AKI was more commonly observed in patients undergoing allogeneic versus autologous HSCT (85.2% in allogeneic vs. 27.8% in autologous, P = 0.005. Mortality was seen in 20 patients (30.8% in 3 months. AKI in the first 2 weeks (P < 0.016 was a significant risk factor for mortality. Incidence of AKI in HSCT is high and accounts for significant mortality and morbidity. RIFLE classification of AKI has prognostic significance among HSCT patients with an incremental trend in mortality.

    Cinacalcet, a calcimimetic drug, has been shown to be efficacious in adult chronic kidney disease (CKD) patients; however, it was not fully studied in pediatric CKD patients. We aimed at assessing the effect of cinacalcet on intact parathyroid hormone (iPTH) secretion in children with CKD-4/5 with iPTH consistently ≥ 300 pg/mL refractory to conventional treatment. This is a prospective cohort analysis of 28 children with uncontrolled hyper-parathyroidism secondary to stage 4 and 5 CKD admitted to a tertiary center during the period from April 2012 to April 2014. Twenty-eight patients with CKD-4/5 were assessed prospectively regarding bone biochemistry, renal ultrasonography, serum iPTH level, and medications. Patients were classified into 3 groups: group 1, 6 patients with CKD-4 on supplemental and supportive therapy; group 2, 6 patients with CKD-5 on hemodialysis and; group 3, 16 patients with CKD-5 on automated peritoneal dialysis. Patients were between the ages of 9 months and 18 years on commencing cinacalcet at doses of 0.5 to 1.5 mg/kg. All patients showed at least a 60% reduction in iPTH (60%-97%). Highly significant reduction in iPTH and serum alkaline phosphatase levels was detected post-cinacalcet. The serum calcium (Ca), phosphate (P), and Ca × P product were unaffected. Treatment was well tolerated with no hypophosphatemia, hypocalcemia, or other adverse effects almost in all patients. Cinacalcet use was proven safe for all pediatric and adolescent patients with CKD-4/5 during the study period, and at the same time most of the patients reached the suggested iPTH target values.

    Objectives. This study is aimed at studying the prevalence and characteristics of different types of headaches in patients with Crohn's disease. Materials and Methods. 51 patients in Crohn's disease group (F/M: 26/25) and 51 patients in control group (F/M: 27/24) were involved. Patients in Crohn's disease group were diagnosed and monitored according to European Crohn's and Colitis Organization diagnostic criteria. The control group composed of healthy subjects with similar age and sex to Crohn's disease group. Headache was classified using the International Headache Society II criteria. Results. Headache was reported by 35/51 (68.6%) patients in Crohn's disease group and 21/51 (41.2%) patients in the control group. The prevalence of headache was statistically high in the group with Crohn's disease (OR: 3.125 (95% CI: 1.38-7.04); p = 0.01). Comparing two groups with respect to their subtypes of headaches resulted in that the tension-type headache was statistically (p = 0.008) higher in Crohn's disease group (26/51) than in the control group (12/51). However, no significant difference was found in the migraine-type headache (p = 1). Conclusions. This study indicates that the prevalence of headache is high in patients with Crohn's disease and most commonly associated with the tension-type headache.

    AIM: To determine predisposing factors leading to surgical delay in elderly patients with acute abdominal conditions and its impact on surgical outcomes.METHODS: A retrospective review of a total of 144 patients aged 60 years and older who had undergone emergency abdominal surgery between 2010 and 2013 at a regional general hospital was analysed. The operations analysed were limited to perforated or gangrenous viscus and strangulated hernia. Patient demographic features, time taken to obtain a computed tomography scan, time taken to surgery and the impact on postoperative morbidity and mortality were analysed.RESULTS: The mean age was 70.5 ± 9.1 years and median time taken to surgery was 9 h. The overall mortality and complication rates(Clavien Dindo 3 and above) were 9% and 13.1% respectively. Diabetes mellitus was a significant predisposing factor which had an impact on surgical delays. Delays in surgery more than 24 h led to higher complication rates at 38.9%(P = 0.003), with multivariate analysis confirming it as an independent factor. Delays in obtaining a computed tomography(CT) scan was also shown to result in higher complication rates(Clavien Dindo 3 and above).CONCLUSION: Delays in performing emergency surgery in elderly lead to higher complication rates. Obtaining CT scans early also may facilitate prompt diagnosis of certain abdominal emergencies where presentation is more equivocal and this may lead to improved surgical outcomes.

    AIM: To evaluate the technical success, diagnostic yield(DY) and therapeutic potential of retrograde single balloon enteroscopy(rS BE). METHODS: A retrospective review of 136 rS BE procedures performed at a tertiary academic referral center from January 2006 and September 2013 was completed. Patient characteristics including age, gender and inpatient status were collected. The indication for the procedure was categorized into one of three groups: Obscure gastrointestinal bleeding(GIB), evaluation for Crohn’s disease and abnormal imaging. Procedural characteristics including insertion depth(ID), procedure time, concordance with pre-procedural imaging and complications were also recorded. Lastly, DY, defined as the percentage of cases producing either a definitive diagnosis or findings that could explain clinical symptoms and therapeutic yield(TY), defined as the percentage of cases in which a definitive intervention was performed, were determined. Mucosal tattooing and biopsy alone were not included in the TY. RESULTS: A total of 136 rS BE procedures were identified. Mean patient age was 57.5(± 16.2) years, 67(49.2%) were male, and 110(80.9%) procedures were performed on an outpatient basis. Indications for rS BE included GIB in 55(40.4%), evaluation of inflammatory bowel disease(IBD) in 29(21.3%), and imaging suggestive of pathology other than GIB or IBD in 43(31.6%). Nine(6.6%) rS BEs were performed for other indications. Mean ID was 68.3(± 39.3) cm proximal to the ileocecal valve and mean time to completion was 41.7(± 15.5) min. Overall, 73(53.7%) cases were diagnostic and 25(18.4%) cases were therapeutic in which interventions(argon plasma coagulation, stricture dilatation, polypectomy, etc.) were performed. Pre-procedural imaging was performed in 88(64.7%) patients. Endoscopic concordance of positive imaging findings was seen in 31(35.2%) cases. Follow up data was available in 93(68.4%) patients; 2(2.2%) reported post-procedural abdominal pain within 30 d following rS BE. There were no other reported complications. CONCLUSION: rS BE exhibits an acceptable diagnostic and TY, rendering it a safe and effective procedure for the evaluation and treatment of small bowel diseases.

    Full Text Available Introduction: The objective of our study was to review the results of percutaneous angioplasty (PTA/stenting in the treatment of patients who presented with symptoms and angiographic findings of chronic mesenteric ischemia (CMI. Materials and Methods: We performed a retrospective analysis of 13 consecutive patients from a single institution who underwent PTA/stenting for the treatment of symptoms suggestive of CMI. Results: All 13 patients in our study were men, and most common presenting symptoms were weight loss and postprandial pain. Atherosclerosis was the most common cause. PTA and stenting was performed in 9 patients and PTA alone was done in 4 patients. Primary technical success rate was 92% with complete resolution of symptoms within 2 weeks in all patients. No statistical difference was noted in primary clinical success rate based on the number of vessels treated or the method of treatment. However, in patients whom SMA was treated had longer duration of symptom-free survival as compared to other vessels. Conclusion: PTA and stenting are very effective therapeutic options for patients presenting with CMI symptoms. It should be considered as the first-line of management in such patients.

In this study, the epidemiological data of the patients are presented and analyzed. Attention was paid to diagnostic imaging and its accuracy in the diagnosis and classification of choledochal cyst. Most cases of choledochal cyst disease have type I and IV-A cysts according to the Todani classification system, which support the etiological theories of choledochal cyst, especially Babbitt's theory of the anomalous pancreaticobiliary duct junction, which are clearly stated. The difficulties and hazards of surgical management and methods used to avoid operative complications are clarified. Early and late postoperative complications are also included. This study should be followed by multicenter studies throughout Egypt to help assess the incidence of choledochal cysts in one of the largest populations in Africa and the Middle East.

    Bevezetés: Heveny myeloid leukaemiában a fiatal felnőttek (myeloid leukaemiás betegeik kezelésével szerzett tapasztalataik elemzését tűzték ki célul. Módszer: 2007–2013 között 173 heveny myeloid leukaemiás beteget kezeltek. A betegeket a European LeukemiaNet javaslata alapján osztályozták. Vizsgálták az életkor, a „de novo” vagy „szekunder” betegség, a daunoblastin dózisa, a bortezomib, a minimális residualis betegség és a betegség lefolyása közötti összefüggést. Eredmények: A fiatal betegek ötéves túlélése 25%, az időseké 2% volt. A túlélést a prognosztikai tényezők jelentősen befolyásolták: a fiatal, jó prognózisú betegek túlélése 50% volt. Fiataloknál a 90 mg/m2 daunoblastin előnyös volt, míg a 45 mg/m2 és 60 mg/m2 hatékonysága között nem volt jelentős különbség. A bortezomibbal kiegészített standard indukciós kezelés ígéretesnek tűnt, de ennek megítéléséhez nagyobb számú beteg vizsgálata szükséges. Következtetések: A remisszió kialakulásának gyorsasága és mélysége, valamint a kiindulási fehérvérsejtszám jelentősen befolyásolhatják a betegség lefolyását a European LeukemiaNet osztályozás szerinti azonos csoportokon belül is.

    Science.gov (United States)

    2012-01-01

    Background Hyponatremia occurring as a result of the syndrome of inappropriate antidiuretic hormone secretion (SIADH) or cerebral salt wasting syndrome is a common complication in patients with subarachnoid hemorrhage (SAH). The efficacy and safety of urea as treatment for SIADH-induced hyponatremia has not been reported in this population. Methods This is a retrospective analysis of all patients admitted to our department for nontraumatic SAH between January 2003 and December 2008 (n = 368). All patients with SIADH-induced hyponatremia (plasma sodium  20 mEq/L, and osmolality > 200 mOsm/kg; absence of overt dehydration or hypovolemia; no peripheral edema or renal failure; no history of adrenal or thyroid disease) routinely received urea per os when hyponatremia was associated with clinical deterioration or remained less than 130 mEq/L despite saline solution administration. Results Forty-two patients developed SIADH and were treated with urea. Urea was started after a median of 7 (IQR, 5–10) days and given orally at doses of 15–30 g tid or qid for a median of 5 (IQR, 3–7) days. The median plasma sodium increase over the first day of treatment was 3 (IQR, 1–6) mEq/L. Hyponatremia was corrected in all patients, with median times to Na+ >130 and >135 mEq/L of 1 (IQR, 1–2) and 3 (IQR, 2–4) days, respectively. Urea was well tolerated, and no adverse effects were reported. Conclusions Oral urea is an effective and well-tolerated treatment for SIADH-induced hyponatremia in SAH patients. PMID:22647340

    To determine the characteristics of atherosclerotic renal artery stenosis (ARAS) in a cohort of patients who attended the Nephrology Department of NMC Specialty Hospital in Dubai from 2006 through 2010, including their clinical and investigational features and their response to various remedial modalities, we studied 20 patients with a diagnosis of ARAS based on magnetic resonance angiography. Three (15%) patients developed acute renal failure (ARF) after the initiation of angiotensin converting enzyme inhibitors or angiotensin II receptor blockers and 13 (65%) patients presented with chronic kidney disease (CKD) of either ischemic nephropathy or nephroangiosclerosis etiology. Four (20%) patients presented with resistant arterial hypertension (RAH). Plasma renin activity was elevated in all the patients. Fifteen (75%) patients were diabetics. We conclude that CKD was the main presentation of ARAS followed by RAH and ARF in our study. Diabetes Mellitus was the main risk factor for ARAS found in our study.

    AIM: To examine the efficacy and complications of colonoscopic resection of colorectal polypoid lesions.METHODS: We retrospectively reviewed 1354 polypectomies performed on 1038 patients over a tenyear period. One hundred and sixty of these were performed for large polyps, those measuring ≥ 20 mm.Size, shape, location, histology, the technique of polypectomy used, complications, drugs assumption andassociated intestinal or extra intestinal diseases wereanalyzed. For statistical analysis, the Pearson χ2 test,NPC test and a Binary Logistic Regression were used.RESULTS: The mean patient age was 65.9±12.4 years,with 671 men and 367 women. The mean size of polyps removed was 9.45±9.56 mm while the size of large polyps was 31.5:1:10.8 mm. There were 388 pedunculated and 966 sessile polyps and the most common location was the sigmoid colon (41.3%). The most frequent histology was tubular adenoma (55.9%)while for the large polyps was villous (92/160 -57.5%).Coexistent malignancy was observed in 28 polyps (2.1%)and of these, 20 were large polyps. There were 17procedural bleeding (1.3%) and one perforation. The statistical analysis showed that cancer is correlated to polyp size (P < 0.0001); sessile shape (P < 0.0001) and bleeding are correlated to cardiac disease (P=0.034),tubular adenoma (P=0.016) and polyp size.CONCLUSION: The endoscopic resection is a simple and safe procedure for removing colon rectal neoplastic lesions and should be considered the treatment of choice for large colorectal polyps. The polyp size is an importantrisk factor for malignancy and for bleeding.

    Full Text Available The contribution of renal biopsy (RB is of major importance in the management of many renal diseases in children. Specific indications for performing biopsy in children include steroid-resistant nephrotic syndrome (NS and secondary nephropathies. The aim of our study was to report the common histological varieties of kidney diseases in children in Morocco. In this retrospective and descriptive study, we included all renal biopsies performed in patients under 16 years in the Department of Pediatrics of Hassan II University Hospital, Fez, Morocco from July 2009 to December 2013. Biopsy samples without glomeruli and those with less than five glomeruli or repeat biopsies on the same patient were excluded from our study. We performed 112 RBs during this period; the average age at the time of RB was 10.05 ± 4 years and the sex-ratio was 1.07. The indications for RB were NS with hematuria and/or renal failure (RF in 32.1%, active urinary sediment in 21.4%, isolated NS in 15.2%, RF in 13.4% and steroid-resistant NS in 10.7% of cases. Primary nephropathies represented 59.8% of cases, with a predominance of minimal change disease (MCD seen in 40.2% of the cases. Secondary nephropathies accounted for 27.7% of the cases, with a predominance of lupus nephritis (11.6%, followed by Henoch-Schonlein purpura nephritis (6.2% of cases and post-streptococcal glomerulonephritis (3.6%. There was one case of hepatitis B virus-associated membranous glomerulonephritis. Chronic glomerulonephritis accounted for 12.5% of the cases. Vascular and tubulo-interstitial nephritis were rare. Our study confirmed that primary glomerular nephropathy was the most common renal disease in children. The most common lesion was MCD. Secondary nephropathies were less frequent, with a predominance of lupus nephritis.

    All patients admitted with pregnancy related acute renal failure (PRAKI) from June 2005 to May 2007 were studied with respect to etiology, clinical features, and outcome of PRAKI. Of 569 cases of acute kidney injury (AKI), 40 (7.02%) cases were related to gestational problems; the age of the patients ranged from 15 to 45 years. Septic abortion was the most common cause of PRAKI, accounting for 20 (50%) cases of which 15 (75%) cases occurred in the first and five (25%) in the second trimester. Other causes were antepartum hemorrhage: six cases (15%), toxemia of pregnancy: six cases (15%), acute gastroenteritis: three cases (7.5%), postpartum hemorrhage: two cases (5%), acute pyelonephritis: two cases (5%), and postpartum, acute kidney injury: one case (2.5%). Dialysis was needed in 60% of the cases and mortality was observed in 20% of the cases. PRAKI continues to be a major concern in our society, causing a high maternal mortality. Septic abortion which has virtually disappeared from developed countries, continues to be a major cause of PRAKI in our society. Hence, there is a need to halt the practice of illegal abortions and improve antenatal care.

    Full Text Available To investigate the molecular basis of β-thalassemia intermedia in Northern Iraq and evaluate its management practices, a total of 74 patients from 51 families were enrolled. The patients were clinically and hematologically reevaluated, and had their β-thalassemia mutations characterized, as well as the number of α-globin genes and Xmn I Gγ −158 (C>T polymorphism studied. Out of 14 β-thalassemia mutations identified, the four most common were IVS-I-6 (T>C [33.3%], IVS-II-I (G>A [21.1%], codon 82/83(−G [10.1%], and codon 8 (−AA [8.1%]. The most common contributing factors to the less severe phenotype of thalassemia intermedia were found to be the inheritance of mild β-thalassemia alleles and the Xmn I polymorphism, while concomitant α-thalassemia had a limited role. Several complications were documented including: pulmonary hypertension in 20.4%, diabetes mellitus in 1.4%, hypothyroidism in 2.9%, and heart failure in 2.7%, while no documented cases of venous thrombosis were found. Compared to their counterparts in several Mediterranean countries, it appears that our patients were much less frequently transfused and had a lower proportion of patients who were splenectomized, on iron chelation, or hydroxycarbamide therapy. Such practices require further scrutiny to ensure that a better level of care is provided and that growth retardation, skeletal changes, and other complications are prevented or reduced.

    Purpose: Evaluation of angioplasty with bare metal stents in infrapopliteal occlusions or severe stenoses in patients with critical limb ischemia. Material and methods: Percutaneous stent angioplasty was performed in 58 limbs in 47 patients with critical limb ischemia (CLI) in Rutherford stage 4-6. Lesions with up to 5 cm in length with at least one patent vessel below the obstruction were treated. 121 bare metal stents (diameter of 2.5-4 mm; length of 18-38 mm) were implanted. Follow-up examinations were performed up to 12 months postinterventionally using clinical examination, ABI calculation, and color-coded duplex sonography. Patency rates were calculated on the basis of the Kaplan-Meier analysis. Results: Technical success was achieved in 100%. Minor complications (hematoma, distal emboli, vessel dissection) were documented in 5.17% (n = 3) limbs, respectively. The 3-month, 6-month, and 1-year primary patency rate was 93.0%, 78.9% and 66.7%, respectively. 86.9% of the lesions healed postinterventionally. The cumulative limb salvage rate was 96.6%. Conclusion: Stent angioplasty in infrapopliteal arteries is a safe and effective technique for the treatment of patients with CLI. By consequent clinical monitoring high secondary patency rates can be achieved. The use of a bare metal stent seems to result in high limb salvage, primary and secondary patency rates in the mid-term follow-up.

    Full Text Available Aim: Trap neuropathy is characterized by compression of the peripheral nerve into fibro osseous channels in trespassing areas of body segments. Peroneal nerve is the most frequently injured nerve in traumatic injuries of the lower extremities. In the present study, we investigated functional results of surgical treatment of patients with peroneal nerve injury who delayed visiting our clinics after the damage; we also aimed to observe the effects of this delay on prognosis. We interpreted postoperative results of the patients with EMG and physical examination findings. Material and Method: Subjects with peroneal nerve damage who visited our clinics between 2012 and 2015 were included in the present study. EMG and muscle motor strength tests were conducted pre and postoperatively for clinical assessment. Results: Of the 16 patients in the study population, 7 were men and 9 were women. The median age of the subjects was 49.6 years (14-77 years. Admission time was 9 months after injury. Causes of the peroneal nerve damage were as follows: prosthesis surgery in 4 (25%, ankle damage in 2 (12.5%, excessive squatting by agriculture workers in 4 (25%, aggressive exercise in 2 (12.5%, bone fracture in 2 (12.5%, and unknown origin in 2 (12.5%. Discussion: Peroneal nerve injury usually occurs by compression of the nerve at the head or neck of the fibula. Results of decompression surgery are usually compromising in non-traumatic nerve palsies. Period of duration between injury and diagnosis and muscular atrophy are main factors associated with success of treatment.

    Between 1980 and 1996, we transplanted 72 patients with CML using blood stem cells collected at diagnosis before treatment and without any mobilization. The median age of patients at diagnosis was 47.5 years (range 20.5-59.5). The median numbers of nucleated cells and CFU-GM transplanted were 10 x 10(8)/kg and 97 x 10(4)/kg, respectively. The median duration to reach more than 0.5 x 10(9)/l neutrophils and 50 x 10(9)/l platelets was 12 (range 5-19) and 11 days (range 0-79), respectively. Twenty patients (group I) were transplanted in chronic phase either for resistance to IFN (14 patients) (group IA) or because the Sokal index was more than 1.2 (six patients) (group IB). All those patients had preparative regimen with busulfan (4 mg/kg/day x 4) and melphalan (140 mg/m2). They were treated with recombinant alpha-interferon (IFN) after transplant. The cumulative incidence of major cytogenetic response (MCR) at 12 months was 25 +/- 21% (95% CI), the 5-year survival was 75 +/- 42% (95% CI). These results (observed in patients with bad prognosis factors) are similar to those usually observed in CML patients treated by IFN, whatever the Sokal risk. Thus autologous transplantation is able to reproduce for poor prognosis patients the results observed in standard risk patients treated with IFN. This suggests that it could prolong survival. Fifty-two other patients (group II) were transplanted for CML in transformation (accelerated phase = 32; blast crisis = 20) after a preparative regimen containing either total body irradiation (TBI) or busulfan. The median survival was short (10.4 months) and only 21 patients survived more than 1 year. The survival was longer for patients transplanted in accelerated phase (vs blast crisis), those who were due to receive a double transplant (vs single) (34 patients), those who were treated with IFN after transplant (vs hydroxyurea) and for the patients who obtained a complete hematologic response.

    Full Text Available We retrospectively evaluated the efficacy of prophylaxis with pipemidic acid and levofloxacin in transrectal ultrasound guided prostate biopsy (TRUSP-Bx. From January 2002 to December 2004, patients receiving oral pipemidic acid 500 mg twice daily for three days with or without a preoperative intravenous cefazolin 1 gm injection comprised group A. Between January 2005 and December 2009, patients receiving oral levofloxacin 500 mg one hour before biopsy comprised group B. We calculated the annual febrile urinary tract infection (fUTI rates. Patients’ characteristics, including age, prophylactic antibiotics, biopsy core numbers, pathologic results, PSA, and the spectrums and susceptibility of pathogens, were also evaluated. A total of 1313 (35.5% patients belonged to group A, while 2381 (64.5% patients belonged to group B. Seventy-three patients experienced postoperative infectious complications. There was a significant difference in the fUTI rate between groups A and B (3.7% versus 1.0%, P<0.001. The yearly fUTI rates varied from 0.6 to 3.9% between 2002 and 2009. Of the 73 patients with fUTI, those receiving levofloxacin prophylaxis were more likely to harbor fluoroquinolone-resistant pathogens (P<0.001. E. coli was the most common pathogen in both groups. Levofloxacin remains effective and appears superior to pipemidic acid based prophylaxis.

    Hajeong Lee

    Full Text Available Research on the prognosis of IgA nephropathy (IgAN has focused on renal survival, with little information being available on patient survival. Hence, this investigation aimed to explore long-term patient outcome in IgAN patients. Clinical and pathological characteristics at the time of renal biopsy were reviewed in 1,364 IgAN patients from 1979 to 2008. The outcomes were patient death and end stage renal disease (ESRD progression. Overall, 71 deaths (5.3% and 277 cases of ESRD (20.6% occurred during 13,916 person-years. Ten-, 20-, and 30-year patient survival rates were 96.3%, 91.8%, and 82.7%, respectively. More than 50% patient deaths occurred without ESRD progression. Overall mortality was elevated by 43% from an age/sex-matched general population (GP (standardized mortality ratio [SMR], 1.43; 95% confidence interval [CI], 1.04-1.92. Men had comparable mortality to GP (SMR, 1.22; 95% CI, 0.82-1.75, but, in women, the mortality rate was double (SMR, 2.17; 95% CI, 1.21-3.57. Patients with renal risk factors such as initial renal dysfunction (estimated glomerular filgration rate <60 ml/min per 1.73 m(2; SMR, 1.70; 95% CI, 1.13-2.46, systolic blood pressure ≥ 140 mmHg (SMR, 1.88; 95% CI, 1.19-2.82 or proteinuria ≥ 1 g/day (SMR, 1.66; 95% CI, 1.16-2.29 had an elevated mortality rate. Patients with preserved renal function, normotension, and proteinuria <1 g/day, however, had a similar mortality rate to GP. When risk stratification was performed by counting the number of major risk factors present at diagnosis, low-risk IgAN patients had a mortality rate equal to that of GP, whereas high-risk patients had a mortality rate higher than that of GP. This investigation demonstrated that overall mortality in IgAN patients was higher than that of GP. Women and patients with renal risk factors had a higher mortality than that of GP, Therefore, strategies optimized to alleviate major renal risk factors are warranted to reduce patient mortality.

    Full Text Available OBJECTIVE: To analyze the short and long term safety and efficacy of ureteroscopic evaluation and management of chronic unilateral hematuria. METHODS: We retrospectively reviewed patients with chronic unilateral hematuria from 1987 to 2008. The distal to middle ureter was evaluated with a semi-rigid ureteroscope without a guidewire. Subsequently, the flexible ureteroscope was advanced into the upper ureter to the renal pelvis using a low-pressure automated irrigant system (Uromat™. Lesions identified ureteroscopically were treated with diathermy fulguration. RESULTS: One hundred and four (56 male, 48 female patients were identified, with a median age of 37 (14-80 years and median follow-up of 139 (34-277 months. The median preoperative duration of gross hematuria was 5 (1-144 months. Endoscopic findings included 61 (56% minute venous rupture (MVR; a venous bleeding without clear abnormalities, 21 (20% hemangioma (vascular tumor-like structure, 3 (3% varix (tortuous vein, 1 (1% calculus and 18 (17% no lesions. The incidence of "no lesions" was less in the recent 12 years (9% than the first 10 years (27%, while the incidence of MVR increased from 40 to 66% (p<0.05. All patients were treated endoscopically. Immediate success rate was 96% (100% in the recent 12 years. Long-term recurrent gross hematuria rate was 7%. Six resolved spontaneously and only 1 required ureteroscopy, revealing a different bleeding site. CONCLUSION: Ureteroscopy and diathermy fulguration is highly useful for evaluation and treatment of chronic unilateral hematuria. Sophisticated technique and improved instrumentation contributes to a better outcome.

    Aim: An important life-threatening complication of intensive chemotherapy administered in children with leukemia is febrile neutropenia. The objective of this study was to evaluate the clinical features and consequences of febrile neutropenia attacks in children who were treated for acute lymphoblastic leukemia. Material and Methods: Nighty-six children who received chemotherapy for acute lymphoblastic leukemia in our center between January 1995 and December 2010 were included in the study. The data related to demographic characteristics, treatment features, relapse and febrile neutropenia incidences, risk factors, culture results and prognosis were retrospectively evaluated from the patients’ files. Results: A total of two hundred-ninety nine febrile neutropenia attacks observed in the patients during initial treatment and relapse treatment were evaluated. When the incidence of febrile neutropenia was evaluated by years, it was observed that the patients treated after year 2000 had statistically significantly more febrile neutopenia attacks compared to the patients treated before year 2000. When the incidences of febrile neutropenia during initial treatment and during relapse treatment were compared, it was observed that more febrile neutropenia attacks occured during relapse treatment. Fifty-nine percent of all febrile neutropenia attacks were fever of unknown origin. Eighty microorganisms grew in cultures during febrile neutropenia throughout treatment in 75 patients; 86% were bacterial infections (50% gram positive and 50% gram negative), 8% were viral infections and 6% were fungal infections. Coagulase negative staphylococcus (n=17) was the most frequent gram positive pathogen; E. Coli (n=17) was the most commonly grown gram negative pathogen. Conclusions: In this study, it was found that an increase in the incidence of febrile neutropenia occured in years. Increments in treatment intensities increase the incidence of febrile neutropenia while improving survival. Evaluation of febrile neutropenia results by hematology-oncology units in years will be directive in early and successful treatment. PMID:27489464

    The spectrum of clinical and electrophysiological features in hereditary neuropathy with liability to pressure palsies (HNPP) is broad. We analyze a series of Brazilian patients with HNPP. Correlations between clinical manifestations, laboratory features, electrophysiological analyze, histological and molecular findings were done. In five cases, more than one episode occurred before diagnosis. Median nerve in the carpal tunnel at the wrist, ulnar nerve in its groove at the elbow, fibular nerve in the head of the fibula at the knee, radial nerve in its groove of the humerus and suprascapular nerve in its notch at the supraspinous fossa were found as focal neuropathies. One patient presented with persistent writer’s cramp after ulnar nerve palsy. Nerve conduction studies showed focal neuropathy in all patients and concomitant generalized symmetrical neuropathy in eight patients. Molecular analysis of the PMP22 gene detected deletion of the 1.5-Mb fragment in all patients. PMID:27761228

    Exfoliative cheilitis (EC) is a rare inflammatory condition affecting the vermilion of the lips and characterized by production of a thick keratin scale. Given the limited available data, the approach to optimal management of EC remains unclear. The objective of this retrospective study was to characterize the clinical features, management, and outcomes of a series of patients with EC. Fifteen patients with a median age of 59 years and a female-to-male ratio of 2:1 were diagnosed with EC from 2000 to 2010. Parafunctional lip licking (53%) and a history of psychiatric disorders (40%) were common. Ten patients (66%) returned for follow-up, with an overall response rate (partial or complete) of 80% at a median of 2 months, most frequently associated with the use of topical calcineurin inhibitors or moisturizing agents. Management of EC with topical calcineurin inhibitors and moisturizing agents is associated with clinical improvement, but prospective trials are needed.

    Full Text Available Background/Aim: Gastrointestinal stromal tumors (GISTs are the most common mesenchymal tumors of the gastrointestinal tract. Surgery remains the mainstay of curative treatment. Our objective is to evaluate the outcome of surgical treatment of primary gastric GIST. Materials and Methods: Between January 1997 and April 2008, thirty seven consecutive patients underwent resection for GISTs (35 patients with primary gastric GISTs and two patients with intestinal GISTs who were excluded from the study. These patients underwent upper endoscopy ± biopsy, barium meal and abdominal CT scan. Patients′ demographics and clinical presentations were analyzed. Perioperative parameters measured included operative times, estimated blood loss, intraoperative finding, surgical techniques, morbidity and length of hospitalization. Recurrence and survival were also analyzed. Results: Of the 35 patients with gastric GISTs included in the study, 63% were female. The median age was 59 ± 14 years (range, 23 to 75 years. The primary presenting symptoms were bleeding and dyspepsia; 43% of these tumors were located mainly in the body of the stomach. Tumor size was < 10 cm in 80% of the patients. The average tumor size was 6.3 ±3.2 cm (range from 3 to 13 cm. Regarding the surgical management, 20 patients (57% underwent gastric wedge resection, eight patients (23% underwent partial gastrectomy and the remaining seven patients (20% underwent total gastrectomy. Radical resections were found in 32 patients (91.5% while palliative resections were found in three patients (8.5%. The resected lymph nodes were negative in 32 patients (91.5%. Recurrence was noted in three patients, with a median time to recurrence of 14.3 months (range, 7 to 28 months. The three- and five-years survival in patients who underwent wedge resection was 92% and 81%, respectively, where it was 95% and 87%, respectively, in patients who underwent gastrectomy (either partial or total. There were no major intraoperative complications or mortalities. Conclusion: Complete surgical resection either through wedge resection or gastrectomy with negative margins remains the gold standard treatment in the management of patients with primary resectable gastric GISTs.

    Full Text Available Etiology determination of neurodevelopmental disabilities (NDDs currently remains a worldwide common challenge on child health. We herein reported the etiology distribution feature in a cohort of 285 Chinese patients with NDDs. Although concrete NDD etiologies in 48.4% of the total patients could not be identified, genetic diseases (with the proportion of 35.8% in the total cases including inborn errors of metabolism (IEM and congenital dysmorphic diseases, constituted the commonest etiology category for NDDs in this study. The two key experimental technologies in pediatric metabolomics, gas chromatography-mass spectrometry (GC-MS, and tandem mass spectrometry (MS-MS, proved to be substantially helpful for the exploration of the NDD etiologies in this clinical investigation. The findings in this paper provided latest epidemiologic information on the etiology distribution of NDDs in Chinese, and the syndromic NDDs caused by citrin deficiency and the novel chromosomal karyotype, respectively, further expanded the etiology spectrum of NDDs.

    Full Text Available Outpatient parenteral antimicrobial therapy (OPAT is a well-established method in medical specialties. Its use in renal transplant recipients has not been thoroughly explored. No guidelines within this patient subset exist. This study describes OPAT outcomes within a UK teaching hospital renal transplant population. Renal function, mapped by estimated glomerular filtration rate (eGFR, and clinical response to infection were collected retrospectively. A total of 635 antimicrobial episodes were administered to nine renal transplant patients over 12 discrete OPAT courses during the study period. Eleven of 12 OPAT courses (91.67% produced a clinical improvement in infection. One course was terminated due to immunosuppressive-related neutropenia. No patient required admission due to failure of OPAT or adverse events. There was no significant change in graft function throughout the OPAT courses compared with baseline renal function (ANOVA, P = 0.06. One minor line infection was reported. This was treated conservatively and did not interrupt the OPAT. OPAT is safe and clinically effective in our renal transplant recipients with no significant deterioration in eGFR. The incidence of adverse events, specifically line complications, was lower in our population than those reported in the literature. Future work should develop OPAT guidelines designed for transplant recipients to outline the degree of monitoring required.

    1997-12-01

    This is a report on 60 consecutive patients with chronic myeloid leukemia (CML) who received an allogeneic bone marrow transplant (BMT) in this Unit. Donors were HLA-identical siblings (SIB) (n = 36) or unrelated donors (MUD) (n = 24) matched by serology for HLA A and B and by molecular biology for HLA DR. All patients were prepared with cyclophosphamide 120 mg/kg and fractionated total body irradiation 10-12 Gy. GVHD prophylaxis consisted of cyclosporin A (CsA) starting on day -7 and short-course methotrexate. Bone marrow was unmanipulated in all cases. Cytomegalovirus prophylaxis consisted of acyclovir for SIBs and foscarnet for MUDs. When compared to SIB transplants, MUD patients were younger (29 vs 36 years; P = 0.002), had younger donors (31 vs 39; P = 0.001), had a longer interval between diagnosis and BMT (1459 vs 263 days; P < 0.001) and received a smaller number of nucleated cells at transplant (3.3 vs 4.4 x 10(8)/kg; P = 0.003). More MUDs had advanced disease (50 vs 17%, P = 0.005). The median day to 0.5 x 10(9)/l neutrophils was similar in both groups (18 days for SIBs vs 17 days for MUDs; P = 0.06); the median platelet count on days +30, +50, +100 was significantly (P < 0.01) higher in SIB than in MUD patients (122 vs 38, 113 vs 50 and 97 vs 45 x 10(9)/l, respectively). Acute GVHD was scored as absent-mild, moderate, or severe, in 36, 58 and 6% of SIBs vs 25, 42 and 33% in MUD patients (P = 0.01). Chronic GVHD was comparable (P = 0.1). The actuarial risk of CMV antigenemia at 1 year was 60% in both groups. There were six deaths in SIB patients (two leukemia, two infections, one GVHD, one pneumonitis) and four deaths in MUD patients (three acute GVHD and one infection). Fifty patients survive with a median follow-up of 656 days for SIBs and 485 for MUDs. The actuarial 3-year transplant-related mortality is 12% in SIBs and 17% in MUDs (P = 0.5); the actuarial relapse is 18% in SIBs vs 6% in MUDs (P = 0.4) and 3-year survival 78% in SIBs vs 82% in MUDs (P = 0.7). This study suggests that survival of CML patients after marrow transplantation from unrelated or sibling donors is currently similar, provided the former are well matched. The increased incidence of GVHD in MUD patients is possibly compensated by a lower risk of relapse.

    Purpose: This prospective study aims to present the overall success rate, safety and long-term outcome of vibrational angioplasty technique, in the treatment of chronic total femoropopliteal occlusions in our institute. Methods: Between October 2000 and December 2008, patients with chronic total femoropoliteal arterial occlusions, treated with vibrational angioplasty during the same session after a failed attempt with conventional recanalization technique, were included. Patient's follow up included serial ankle-brachial index measurements and arterial duplex ultrasound examinations at 1, 3, 6, 12, 24, 36 and 48 months. Results: Twenty-seven patients (16 males and 11 females) and twenty-eight lesions were included in our study. Twenty-five lesions (89.3%) were successfully recanalized. Pain relief was noticed in twenty-one cases. From ten lesions with tissue loss (ulcer or gangrene) in successfully recanalized occlusions, six healed without major, or minor amputation. One non-healing amputation stump was healed after recanalization, without further complications. Four limbs underwent amputation (one minor and three major) despite successful recanalization, however all had an excellent healing of the amputation stump without further complications. The Kaplan–Meier test demonstrated 90%, 85% and 70% amputation-free survival rate at 12, 24 and 36 months, respectively. No major or minor complications were encountered. Conclusions: Vibrational angioplasty is a safe, effective and durable endovascular technique for the treatment of chronic total occlusions in patients with limb ischemia that would be difficult to recanalize using conventional intraluminal techniques.

    La pancreatite rimane ad oggi la maggiore complicanza dell’ERCP nonostante numerose misure tese alla sua prevenzione siano state proposte negli anni. La sua incidenza è del 3.5% e raggiunge in alcune serie di casi anche il 25%; solitamente è lieve-moderata nel 90%. La stratificazione dei pazienti in base al grado di rischio è necessaria per destinare i casi più complessi a centri di terzo livello presenti nel territorio; per far questo, un’analisi dei possibili fattori di rischio è stata originariamente proposta da Freeman ed è poi stata modificata dall’ESGE sulla base dei contributi dei singoli centri, con importanti modifiche. Il presente studio analizza l’incidenza di pancreatite post- ERCP in un centro di terzo livello analizzando, sulla scorta dei fattori di rischio proposti, l’aderenza dei dati. Negli anni 2012-2013, 492 pazienti sono stati sottoposti ad ERCP da due esperti endoscopisti. Secondo le classificazioni di Freeman e Cotton sono state osservate 14 PEP (2.8%), di cui 6 lievi, 4 moderate e 4 severe. È stata condotta un’analisi multivariata che ha evidenziato come fattori di rischio l’elevato numero di tentativi di incannulamento della via biliare e l’iniezione di mezzo di contrasto nel dotto pancreatico; sono risultati fattori protettivi l’early pre-cut e il fallimento della procedura con la sua interruzione. Nella discussione sono state inoltre brevemente analizzate le varie misure profilattiche, quali il posizionamento di protesi pancreatiche e l’utilizzo dei FANS. È interessante notare come i nostri risultati rafforzino gli ultimi orientamenti nel management dell’ERCP, circa l’utilizzo della tecnica di incannulamento filo-guidato e del pre-cut; questi infatti riducono il numero di tentativi di incannulamento ed il conseguente trauma alla papilla promuovendo un incannulamento biliare selettivo e prevenendo l’iniezione di mezzo di contrasto nel dotto pancreatico. Nonostante la pancreatite sia un’ineludibile complicanza dell’ERCP, reputiamo che questi accorgimenti tecnici possono essere utili nel prevenire la sua insorgenza.

    The purpose of this study was to evaluate retrospectively the clinical performance of the Bicarbon valve (Sorin Biomedica Cardio, Saluggia, Italy) implanted at our center in Japan. Between January 1997 and December 2011, 415 patients in our institution were implanted with the Bicarbon valve. Nine of these recipients were excluded from the study because they had already undergone valve implantation and received a Bicarbon valve in a different position. The remaining patients were analyzed for evaluation of the postoperative clinical outcomes. Of the 406 patients (mean age 60.2 ± 11.7 years), 179 underwent aortic valve replacement (AVR), 149 mitral valve replacement (MVR), and 78 both aortic and mitral valve replacement (DVR). There were 10 early deaths (2.5 %: 4 in the AVR group and 6 in the MVR group). Three hundred eighty-nine patients were followed up (95.8 % completeness of follow-up) with a mean follow-up of 6.6 ± 4.2 years overall (AVR 6.8 ± 4.2, MVR, 6.7 ± 4.4, and DVR 5.7 ± 3.4 years) and a cumulative follow-up of 2661 patient-years (1214, 1001, and 446 patient-years for AVR, MVR, and DVR, respectively). Ninety-nine patients died (3.7 % per patient-year: 22 valve-related and 77 valve-unrelated deaths). Survival at 10 years was 74.1 ± 4.0 % in the AVR group, 73.7 ± 4.2 % in the MVR group, and 61.0 ± 7.9 % in the DVR group. The linearized incidence of thromboembolic complications, bleeding complications, prosthetic valve endocarditis, paravalvular leaks, and sudden death in all patients was 0.5 %, 0.5 %, 0.2 %, 0.2 %, and 0.4 % per patient-year, respectively. The incidence of valve-related complications and reoperation was 1.6 % and 0.4 %, respectively. No other valve-related complications were observed. The Bicarbon prosthetic heart valve has shown excellent clinical results and is associated with a low incidence of valve-related complications.

Results: One hundred and forty-four patients were included in the study. The mean±SD of age at diagnosis was 6.7 ± 3.7 years. The median duration of symptoms was 10 days (IQR; 5-14. The most commonly reported presenting symptoms were polyuria (94%, polydipsia (82%, and weight loss (59%. Diabetic ketoacidosis at initial presentation was diagnosed in 31% of the patients. Different insulin regimens were prescribed: multiple daily injections in 109 (76% patients, twice daily insulin regimen in 23 (16% patients, and insulin pump therapy in 12 (8% patients. Family history of type 1 diabetes mellitus was present in 31 (22% patients. There were no significant differences in presenting complaints (polyuria, p=0.182; polydipsia, p=0.848, duration of symptoms (p=0.331, reported weight loss (p=0.753, or diabetic ketoacidosis at presentation (p=0.608 between patients with and without family history of type 1 diabetes mellitus. Conclusion: Polyuria, polydipsia and weight loss are the most common presenting symptoms. Family history of type 1 diabetes mellitus is highly prevalent among the studied patients. Diabetic ketoacidosis was found to be less common in Oman compared to other diabetes centers in the Middle East.

Objective: To prospectively analyze the outcomes associated with TCC placement by nephrologists with expertise in such procedure, in different time periods at the same center. The impact of vancomycin or cefazolin as prophylactic antibiotics on the infection outcomes was also tested. Patients and methods: Hemodialysis patients who presented to such procedure were divided into two cohorts: A (from 2004 to 2008 and B (from 2013 to 2015. Time from TC to TCC conversion, prophylactic antibiotics, and reasons for TCC removal were evaluated. Results: One hundred and thirty patients were included in cohort A and 228 in cohort B. Sex, age, and follow-up time were similar between cohorts. Median time from TC to TCC conversion was longer in cohort A than in cohort B (14 [3; 30] vs 4 [1; 8] days, respectively; P<0.0001. Infection leading to catheter removal occurred in 26.4% vs 18.9% of procedures in cohorts A and B, respectively, and infection rate was 0.93 vs 0.73 infections per 1,000 catheter-days, respectively (P=0.092. Infection within 30 days from the procedure occurred in 1.4% of overall cohort.

    To determine the outcomes of pediatric renal transplant recipients who received immunosuppression consisting of early withdrawal of corticosteroids at a single Northern California center. Protocols using minimal steroid exposure have been recently reported in adult transplant recipients with successful results. We examined the outcomes of pediatric renal transplant recipients who were managed at our center using a protocol with very early discontinuation of steroids after renal transplantation. We retrospectively studied the medical records of all renal transplant recipients followed at the Children's Hospital at the University of California, Davis Medical Center from 01/2004 to 12/2005. All patients were less than 18 yr of age at the time of transplantation. The immunosuppressive protocol included three tapering daily doses of methylprednisolone, together with five doses of thymoglobulin followed by maintenance therapy with tacrolimus and MMF. Eight patients with equal numbers of males and females were transplanted during this time period. There were equal numbers of Caucasians, African-Americans, Hispanics, and Asians. A total of 37.5% (3/8) of the subjects received preemptive transplantation, 25% (2/8) received peritoneal, and 37.5% (3/8) received hemodialysis before transplantation. The median (range) age at transplantation was 12.3 (3.1-16.0) year with a follow-up of 1.7 (0.9-2.8) year. At one yr post-transplantation, 57% (4/7) of patients still required anti-hypertensives. Three children required erythropoietin supplementation after transplantation. The mean delta height standard deviation score at 12 months was 0.20 +/- 0.56. There were no episodes of clinical acute rejection. One patient switched from tacrolimus to sirolimus due to biopsy-proven CAN. No patient became diabetic or required hypoglycemic agents. Surveillance biopsies showed no subclinical acute rejection in any patient. Steroid-free immunosuppression is safe in children after renal transplantation. Larger number of patients and longer follow-up are required to further confirm the effectiveness and safety of immunosuppression with rapid steroid discontinuation.

    We conducted a retrospective study of genitourinary tuberculosis (TB) among males attending a hospital in the northern Himalayan region of India. Records from 1 January 1997 to 31 December 2009 were reviewed for clinical history, relevant radiological findings laboratory data, histopathology and treatment. Of the 1,113 male urogenital non-neoplastic specimens received at the histopathology laboratory of the hospital, tuberculosis was diagnosed in 25 cases (2.2%). Urinary bladder and prostate were the most common organs involved. Thirty-six percent of cases had a previous history of TB; 12% of cases presented with no symptoms. Ziehl-Neelsen staining was positive in 72% of cases. Cultures were positive for TB in 42.8% of cases and polymerase chain reaction was positive in two cases in which it was performed. Antituberculosis treatment was required for up to 12 months in some cases and surgery was required in 32% of cases. Genitourinary TB in this study had varying presentations. Cases having strong clinical and radiological findings and suggestive histopathology for tuberculosis, even without demonstration of mycobacteria may be considered for TB treatment, particularly in endemic areas. Patients living in more remote areas may have more specific and severe symptoms due to late presentation. Histopathology plays a crucial role in diagnosis due to lack of sophisticated techniques. The emphasis should be on early detection followed by prompt treatment to avoid further complications.

    Full Text Available Abstract Background Adenocarcinoma of the small bowel is a relatively rare malignancy as compared to the other malignancies of the gastrointestinal tract. Nonspecific presentation and infrequent occurrence often leads to a delay in diagnosis and consequent poor prognosis. Various other factors are of prognostic importance while managing these tumors. Methods The medical records of a total of 27 patients treated for adenocarcinoma of the small bowel at Providence Hospital and Medical Centers from year 1990 through 2003 were reviewed retrospectively. Data were analyzed using SPSS software (version 10.0; SPSS, Inc., Chicago, IL. Survival analyses were calculated using the Kaplan Meier method with the log rank test to assess the statistical significance. The socio-demographics (age, gender were calculated using frequency analyses. Results The patients included nine males and eighteen females with a median age at diagnosis of 62 years. Only 48% of the patients had an accurate preoperative diagnosis while another 33% had a diagnosis suspicious of small bowel malignancy. None of the patients presented in stage 1. The cumulative five-year survival was 30% while the median survival was 3.3 years. There was no 30-day mortality in the postoperative period in our series. Conclusion The univariate analysis demonstrated that tumor grade, stage at presentation, lymph nodal metastasis and resection margins were significant predictors of survival.

    PSI has a relatively long tradition in neutron imaging since the first trials were done at its formerly existing research reactor SAPHIR with film methods. This reactor source was replaced after its shutdown in 1994 by the spallation neutron source SINQ in 1996, driven by the 590 MeV cyclotron for protons with presently up to 2.3 mA beam current. One of the first experimental devices at SINQ was the thermal neutron imaging facility NEUTRA, which was designed from scratch and has been the first device of its kind at a spallation source. Until now, NEUTRA has been successfully in use for many investigations in a wide range of studies covering fuel cell research, environmental behavior of plants, nuclear fuel inspection and the research on cultural heritage objects. It has been the host of PhD projects for students from all over Europe for years. In a previous meeting it has been offered as a European reference facility. Some of its features were really adapted to the layout of new installations. In 2004, it was possible to initiate the project of a second beam line at SINQ for imaging with cold neutrons. Previous studies have shown the potential of this option in order to broaden the user profile and to extend the scientific basis for neutron imaging. It was inaugurated with a workshop at PSI in 2005. The user service was started at the facility ICON in 2006. Beside the setup, installation and optimization of the facilities, the organization of the user program plays an important role. The two neutron imaging beam lines are equal installations at SINQ among the 14 scientific devices. Therefore, the user approach is organized via "calls for proposals", which are sent out each half year via the "Digital User Office (DUO)" (see http://duo.web.psi.ch). The evaluation of the proposals is done by the "Advisory Committee for Neutron Imaging (ACNI)" consisting of 6 external and PSI internal members. Further requests are given by industrial collaborations. This beam time allocation is handled more directly and in time in order to fulfill the companies' demands. Here, the confidentiality plays a more important role than in scientific studies that are done with the aim of a free publication. It has been possible to earn money regularly from the industrial projects in order to cover the salary cost of some positions within the NIAG group. The permanent improvement of the methodology and performance in neutron imaging is a third major activity of the NIAG team. Running projects in this direction are the permanent insert of a grating interferometry device, improved energy selection with the help of single graphite crystals and utilization of the beam line BOA at SINQ for the energy range between 4 and 15 Å.

    PSI has a relatively long tradition in neutron imaging since the first trials were done at its formerly existing research reactor SAPHIR with film methods. This reactor source was replaced after its shutdown in 1994 by the spallation neutron source SINQ in 1996, driven by the 590 MeV cyclotron for protons with presently up to 2.3 mA beam current. One of the first experimental devices at SINQ was the thermal neutron imaging facility NEUTRA, which was designed from scratch and has been the first device of its kind at a spallation source.

    Based on the 13-year data from the Tropical Rainfall Measuring Mission (TRMM) satellite during 2001-2013, the influencing geographical location of the Tibetan Plateau (Plateau) monsoon is determined. It is found that the domain of the Plateau monsoon is bounded by the latitude between 27° N and 37° N and the longitude between 60° E and 103° E. According to the annual relative precipitation, the Plateau monsoon can be divided into three sections: the Plateau winter monsoon (PWM) over Iran and Afghanistan, the Plateau summer monsoon (PSM) over the central Plateau, and the transiting zone of the Plateau monsoon (TPM) over the south, west, and east edges of the Plateau. In PWM and PSM, the monsoon climatology has a shorter rainy season with the mean annual rainfall of less than 800 mm. In TPM, it has a longer rainy season with the mean annual rainfall of more than 1800 mm. PWM experiences a single-peak monthly rainfall with the peak during January to March; PSM usually undergoes a multi-peak pattern with peaks in the warm season; TPM presents a double-peak pattern, with a strong peak in late spring to early summer and a secondary peak in autumn. The Plateau monsoon also characterizes an asymmetrical seasonal advance of the rain belt. In the east of the Plateau, the rain belt migrates in a south-north orientation under the impact of the tropical and subtropical systems' oscillation. In the west of the Plateau, the rain belt advances in an east-west direction, which is mainly controlled by the regional Plateau monsoon.

  8. Identifying with Science: A case study of two 13-year-old `high achieving working class' British Asian girls

    2012-01-01

    This paper provides an in-depth, 'case study' style analysis of the experiences of two 13-year-old British Asian girls from a larger qualitative study investigating minority ethnic students' aspirations in science. Through the lens of identity as performativity and Bourdieu's notions of habitus and capital, the ways in which two girls engage with the field of science is examined. Samantha is British Indian and Fay is British Bangladeshi and they are both 'top set' students in science, but only one aspired to study triple science, while the other desired to be 'famous'. The experiences of the two girls are explicated in this paper, teasing out their experiences and constructions of science. It is argued that cultural discourses of family, peers and teacher expectations can shape students' perceptions of science and education.

    In this work, we report a unified methodology to express the molecular wavefunctions of water in both vapor and liquid phases by means of a single-center approach. These latter are then used as input data in a theoretical treatment-previously published and successfully tested-for describing the water ionization process in the first Born approximation (Champion et al 2006 Phys. Rev. A 73 012717). The multi-differential and total cross sections also obtained are reported for the two thermodynamical phases investigated and compared to the rare existing experimental and theoretical data.

    Purpose To describe the trends in pathogens and antibacterial resistance of corneal culture isolates in infectious keratitis during a period of 13 years at Hadassah-Hebrew University Medical Center. Methods A Retrospective analysis of bacterial corneal isolates was performed during the months of January 2002 to December 2014 at Hadassah Hebrew University Medical Center. Demographics, microbiological data and antibiotic resistance and sensitivity were collected. Results A total of 943 corneal isolates were analyzed during a 13 year period. A total of 415 positive bacterial cultures and 37 positive fungal cultures were recovered, representing 48% of the total cultures. The Annual incidence was 34.78 ± 6.54 cases. The most common isolate was coagulase-negative staphylococcus (32%), which had a significant decrease in trend throughout the study period (APC = -8.1, p = 0.002). Methicillin-resistant Staphylococcus aureus (MRSA) appears to have a decrease trend (APC = -31.2, P = 0.5). There was an increase in the resistance trend of coagulase-negative staphylococci to penicillin (APC = 5.0, P = keratitis. There was no significant change in the annual incidence of cases of bacterial keratitis seen over the past 13 years. Keratitis caused by MRSA appeared to decrease in contrast to the reported literature. PMID:27893743

    Full Text Available Introduction. Despite the advances in antibiotherapy and critical care management, infectious complications remain among the leading complications after liver transplantation related with mortality and morbidity. This study analysis the incidence and pattern of infections and possible prognostic factors of infectious compli- cations retrospectively in a single center. Patients and Methods. Results of 30 consecutive patients with a primary liver transplantation history in a single center between August 2011 and August 2012 and a positive culture result in the first month in the ICU were analysed retrospectively. Results. During the first 1 month stay in the ICU postoperatively 30 (13,63% patients had at least 1 infection. Total number of infections were 68. Mortality rate of the infected patients was 53,3% (n = 16. Among these infections, 25 (36,76% of them were in deep surgical sites. Eighteen of the 30 patients (60% were infected with a single microorganism. Eleven patients (36,66% had a single infection episode. Microorganism were gram negative in 52 (76,47% of the infections, gram positive in 14 (20,58% of the infections, rest of the 2 (2,94% infections were due to Candidiasis. Among the possible risk factors contributing to mortality, there was a statistically significant dif- ference (p < 0,001 between the platelet counts of the mortality and surviving groups of the patients. Conclu- sion. Infections are among the preventable risk factors for mortality and morbidity after liver transplantation. Our data reveals a significant relation between trombocytopenia and mortality among the infected patients. Further studies focusing on this relation would expose the mechanisms and any possible contribution in cli- nical management of the patients. 

  3. Proximal Tibial Epiphysis Fracture in a 13-Year-Old Male Athlete

    Full Text Available Fractures of the proximal epiphysis of the tibia are rare, representing 0.5 to 3.0% of all epiphyseal injuries. These injuries can damage the popliteal vessels and their bifurcation, affecting the blood supply of the lower limb, as well as the nerves below the knee. Epiphyseal growth arrest is also a potential complication, leading to various angular deformities. We present a case of a 13-year-old male athlete with a posteriorly displaced Salter-Harris type II fracture of the proximal epiphysis of the left tibia who was treated conservatively with closed reduction and cast immobilization.

    The case of a 13 year old girl with renal artery thrombosis and hypertension is described. A cerebrovascular accident and a probable occlusion of the superior mesenteric artery also occurred. Very high levels of 'lupus anticoagulant', anticardiolipin antibodies as well as false positive Venereal Disease Research Laboratory tests were repeatedly shown. Moreover, the patient fulfilled at least four classification criteria for systemic lupus erythematosus, but only a slight positivity for antinucleolar antibodies was present. The striking relation between antiphospholipid antibody levels and clinical events and the treatment of this complex syndrome are discussed. Images PMID:2108619

    Xanthogranulomatous orchitis is an extremely rare inflammatory nonneoplastic lesion of the testis. We report a case of a 13-year-old adolescent boy who presented a painless left hemiscrotal swelling. The subsequent ultrasonography and magnetic resonance imaging revealed the presence of abnormal expanding tissue located in both testes and spermatic cord, reaching the internal inguinal ring. Testicular tumor markers were normal. The frozen section examination of the surgical specimen showed only inflammatory tissue and not neoplastic tissue. No orchiectomy was performed. Definitive histopathologic diagnosis was xanthogranulomatous inflammation. To our knowledge, this is the youngest case of xanthogranulomatous orchiepididymitis and funiculitis found in medical literature.

    this paper aims to investigate the nature and extent of physical restraint deaths reported to Coroners in Australia over a 13-year period. the study comprised a retrospective cohort study of residents dwelling in accredited nursing homes in Australia whose deaths were reported to the Coroners between 1 July 2000 and 30 June 2013 and was attributed to physical restraint. five deaths in nursing home residents due to physical restraint were reported in Australia over a 13-year period. The median age of residents was 83 years; all residents had impaired mobility and had restraints applied for falls prevention. Neck compression and entrapment by the restraints was the mechanism of harm in all cases, resulting in restraint asphyxia and mechanical asphyxia, respectively. this national study confirms that the use of physical restraint does cause fatalities, although rare. Further research is still needed to identify which alternatives strategies to restraint are most effective, and to examine the reporting system for physical restraint-related deaths.

    Ammonia is an integral part of the nitrogen cycle and is projected to be the largest single contributor to each of acidification, eutrophication and secondary particulate matter in Europe by 2020 (Sutton et al., 2008). The impacts of NH3 also include: aerosol production affecting global radiative forcing, increases in emissions of the greenhouse gases nitrous oxide (N2O) and methane (CH4), and modification of the transport and deposition patterns of SO2 and NOx. Therefore, monitoring NH3 global distribution of sources is vitally important to human health with respect to both air and water quality and climate change. We have developed new daily and global ammonia (NH3) products from AIRS hyperspectral measurements. These products add value to AIRS's existing products that have made significant contributions to weather forecasts, climate studies, and air quality monitoring. With longer than 13 years of data records, these measurements have been used not only for daily monitoring purposes but also for inter-annual variability and short-term trend studies. We will discuss the global NH3 emission sources from biogenic and anthropogenic activities over many emission regions captured by AIRS. We will focus their variability in the last 13 years. Validation examples using in situ measurements for AIRS NH3 will also be presented.

    Induction therapy with alemtuzumab followed by lower maintenance immunosuppression (IS) has been associated with reduced morbidity and mortality in abdominal and heart transplantation (TX). In the current study, alemtuzumab, in combination with reduced levels of maintenance IS, was compared to thymoglobulin in combination with standard IS. Sixty consecutive patients who underwent lung transplantation (LUTX) at a single center were prospectively randomized in two groups: group A received alemtuzumab in conjunction with reduced doses of tacrolimus, steroids and mycophenolate mofetil. Group B received thymoglobulin in association with standard dose IS. Patient and graft survival, freedom from acute cellular rejection (ACR), lymphocytic bronchiolitis, bronchiolitis obliterans syndrome, kidney function, infectious complications and posttransplant lymphoproliferative disorder were analyzed. Alemtuzumab induction therapy resulted in complete the absence of ACR episodes ≥ A2 within the first year post-TX. The difference to thymoglobulin was significant (alemtuzumab 0 vs. ATG 0.33; p = 0.019). All other factors studied did not show any differences between the two groups. Alemtuzumab induction therapy after LUTX in combination with reduced maintenance IS significantly reduces higher-grade rejection rates. This novel therapeutic agent had no impact on survival, infections rates, kidney function and incidence of malignancies.
