    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.

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.

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

    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 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.

    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.

    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.

Methods: A total of 131 patients with symptomatic degenerative disc disease refractory to nonsurgical treatment were treated with AxiaLIF at L5–S1, and were followed for a minimum of 1 year (mean: 21 months. Main outcomes included back and leg pain severity, Oswestry Disability Index score, working status, analgesic medication use, patient satisfaction, and complications. Computed tomography was used to determine postoperative fusion status. Results: No intraoperative complications, including vascular, neural, urologic, or bowel injuries, were reported. Back and leg pain severity decreased by 51% and 42%, respectively, during the follow-up period (both P < 0.001. Back function scores improved 50% compared to baseline. Clinical success, defined as improvement ≥30%, was 67% for back pain severity, 65% for leg pain severity, and 71% for back function. The employment rate increased from 47% before surgery to 64% at final follow-up (P < 0.001. Less than one in four patients regularly used analgesic medications postsurgery. Patient satisfaction with the AxiaLIF procedure was 83%. The fusion rate was 87.8% at final follow-up. During follow-up, 17 (13.0% patients underwent 18 reoperations on the lumbar spine, including pedicle screw fixation (n = 10, total disc replacement of an uninvolved level (n = 3, facet screw fixation (n = 3, facet screw removal (n = 1, and interbody fusion at L4–L5 (n = 1.

    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

    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.

    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.

    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.

    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: 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.

    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

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.

    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.

    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.

    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.

    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

    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...

    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.

    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.

    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.

    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

    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.

    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.

    2016-03-01

    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.

    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.

    2009-01-01

    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.

    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.

    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.

    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.

    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.

    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

    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.

    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.

    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.

    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.

    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.

    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.

    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.

    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

    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.

    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

    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.

    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.

    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.

    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.

    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.

    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.)

    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.

    Hayes, Christopher Ruslan

    2012-02-01

    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.

    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.

  12. Endovascular treatment of the subclavian artery aneurysm in high-risk patient - a single-center experience

    2016-01-01

    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 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.

    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.

    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 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.

    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.

    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%).

    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.

    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.

    Dabigatran is an oral direct thrombin inhibitor that is approved for the prevention of stroke and systemic embolism in nonvalvular atrial fibrillation. Dabigatran has several advantages over warfarin including predictable pharmacokinetics and pharmacodynamics which eliminates the need for routine laboratory monitoring, superiority over warfarin in preventing stroke, or systemic embolism without having an increased risk of bleeding. However, as with any anticoagulant, there remains a real chance of bleeding, including major or life-threatening hemorrhage. Many physicians feel comfortable managing bleeding complications on older anticoagulants like warfarin and heparin, due to extensive experience with the medications along with antidotes to reverse their effects as well as established protocols for treating anticoagulant-associated hemorrhage. However, most physicians have limited clinical experience with dabigatran, there is no specific antidote for dabigatran reversal and there is a paucity of protocols, guidelines, and recommendations for how to manage dabigatran-associated hemorrhage. In this review, we present a case series of patients admitted to our institution for management of bleeding while receiving dabigatran. We retrospectively reviewed these cases to evaluate the efficacy and rationale of the various anticoagulation reversal strategies employed in the context of the existing evidence found in the literature. Specific focus is placed on the therapies utilized and the coagulation studies used to manage these patients.

    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

    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.

    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 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 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.

    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 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.

    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.

    AIM: To review and evaluate our experience in laparoscopic cholecystectomy.METHODS: A retrospective analysis was performed on data collected during a 13-year period (1992-2005)from 1220 patients who underwent laparoscopic cholecystectomy.RESULTS: Mortality rate was 0%. The overall morbidity rate was 5.08% (n = 62), with the most serious complications arising from injuries to the biliary tree and the cystic artery. In 23 (1.88%) cases, cholecystectomy could not be completed laparoscopically and the operation was converted to an open procedure. Though the patients were scheduled as day-surgery cases, the average duration of hospital stay was 2.29 d, as the complicated cases with prolonged hospital stay were included in the calculation.CONCLUSION: Laparoscopic cholecystectomy is a safe,minimally invasive technique with favorable results for the patient.

    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

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 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.

    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  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.

    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.

    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.

    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.

    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.

    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

    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.

    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.

    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.

    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

    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.

    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. PMID:24129100

    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.

    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.

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.

    Full Text Available Human epidermal growth factor receptor (HER 2 is amplified in 25 to 30% of breast cancer patients and those whose tumors demonstrate HER 2 gene amplification and protein overexpression have an inferior prognosis manifested by shorter disease-free and overall survival. Trastuzumab, the humanized murine anti-HER 2 monoclonal antibody, inhibits tumor growth when used alone and has synergistic and additive effects when used with chemotherapeutic agents (paclitacel-doxorrubicine. At the present time, the accurate diagnostic assessment of HER 2 is essential for appropriate application of the humanized anti HER 2 monoclonal antibody, trastuzumab, for the treatment of patients with metastatic breast cancer.FDA has approved its use for patients with metastatic breast cancer with HER 2 over-expression since 1998, as a first line treatment in association with paclitaxel or as a second or third line monotherapy. In Argentina, two Consensus Meetings of HER 2 Diagnosis have taken place: the first one on May 15th, 2002 and the second on April 11th, 2003, supported by Roche Laboratories (Herceptin®. In this paper, some topics of these meetings are reviewed. Our single-public center experience is discussed.El receptor para el factor humano de crecimiento epidérmico (HER 2 se encuentra amplificado en el 25 a 30% de los cánceres de mama y aquellas pacientes con tumores que amplifiquen el gen HER 2 y sobreexpresen su proteína tienen un peor pronóstico que se traduce en menor sobreviva global y tiempo libre de enfermedad. Usado como monodroga, Trastuzumab, el anticuerpo monoclonal murino humanizado anti-HER 2, inhibe el crecimiento tumoral y posee efectos sinérgicos y aditivos cuando se agrega a otros agentes quimioterápicos (paclitaxel-doxorrubicina. La determinación diagnóstica precisa del HER 2 es esencial para establecer el uso racional de trastuzumab en el tratamiento de pacientes con cáncer de mama metastático.

    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.

    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.

    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.

    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.

    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.

    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 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.

    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

    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.

    L’obiettivo del nostro studio è la valutazione della strategia chirurgica più idonea nei casi di LABC (Locally Advanced Breast Cancer) in condizioni di ulcerazione e sanguinamento. La diagnosi clinica del LABC prevede nella maggior parte dei casi una massa mammaria estesa associata ad edema, eritema, retrazione e sanguinamento, dolore, superficie cutanea irregolare e coinvolgimento linfonodale. L’intervento chirurgico di scelta per le forme T3-T4 è la mastectomia radicale che rappresenta un trattamento adeguato per il controllo locale della patologia. In caso di forme localmente avanzate e ulcerate, pur essendo forme inoperabili, l’exeresi chirurgica si rende necessaria per una bonifica locale. La presenza di fenomeni di ulcerazione e sanguinamento non rende possibile avviare un trattamento chemioterapico neoadiuvante ed è necessario eseguire interventi chirurgici palliativi. Il trattamento chirurgico stesso richiede mutilazioni ampie ed associate procedure di chirurgia plastica. Spesso per l’estensione della malattia ed il sovvertimento del corpus mammae durante l’exeresi chirurgica della mammella, la sezione su zone esenti da neoplasia non consente la chiusura immediata dei lembi. Abbiamo considerato, su un campione di 288 pazienti affette da carcinoma mammario, 11 donne con forme avanzate fra T4a e T4c (3.8%). E’ stata posta indicazione a trattamento chirurgico perché pazienti provenienti dal Pronto Soccorso con anemizzazione per neoplasie avanzate ulcerate e sanguinanti, non candidabili in prima istanza a chemioterapia neoadiuvante citoriduttiva. Le procedure adoperate per la ricostruzione della mammella sono state in 2 pazienti la rotazione di un lembo muscolo cutaneo, in 4 casi un innesto cutaneo prelevato dalla coscia, in 4 casi è stata utilizzata una matrice dermica biologica - sostituto cutaneo (INTEGRA) che è stata poi sostituita con un successivo innesto cutaneo a distanza di circa 20-30 giorni. Sono state osservate recidive in 2 casi dopo 6 mesi dal trattamento ed exitus dopo 8 mesi dalla diagnosi primaria. In queste pazienti l’obiettivo principale è migliorare la qualità di vita e la gestione della malattia stessa e il chirurgo si trova di fronte al dilemma se affidarle ad un trattamento chemioterapico in prima istanza. Nel nostro studio retrospettivo il follow-up è stato breve, proprio perché essendo forme avanzate le pazienti non avevano una lunga aspettativa di vita e sono comunque decedute a distanza di pochi mesi (4 - 9 mesi) rendendo difficile la redazione di un database sulla qualità della vita. I nostri risultati confermano che l’innesto cutaneo e il sostituto acellulare biologico sono valide opzioni di ricostruzione nelle pazienti con carcinoma mammario localmente avanzato esteso, per migliorare la qualità della vita.

    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.

    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...

    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.

    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.

    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.

    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).

    Full Text Available AimThe aim of this study was to determine the clinical characteristics and prevalence of HLA B27 in patients with psoriatic arthritis presenting to a tertiary care centre in South India. BackgroundAlthough the prevalence of psoriasis is high in India, there is paucity of data, especially on Ps A. Materials and methodsThis retrospective study included 141 patients satisfying the ClASsification criteria for Ps A (CASPAR. Demographic, clinical, and laboratory data of the patients were collected through personal interviews, clinical examination, appropriate investigations, and analysis of case records. HLA-B27 typing by PCR method was done for all patients. ResultsAmong the 141 patients, 89 subjects were males and 52 were females, and the male to female ratio was 1.7:1. Polyarthritis (n=51, 36.2% was the most common Ps A subtype noted during the study, followed by oligoarthritis (n=48, 34%, spondyloarthropathy (n=29, 20.6%, distal interphalangeal (DIP predominant arthritis (n=25, 7.8%, and arthritis mutilans (n=2, 1.4%. Arthritis preceded skin involvement in 9.2% (n=13 of the cases. Dactylitis was seen in 24.1% (n=34 of the patients. Extra-articular features like enthesitis (n=16, 11.3% and eye involvement (n=1, 0.7% were also observed. Deformities were seen in 32.6% (n=46 of the subjects. The most common type of psoriatic skin lesion noted was psoriasis vulgaris (n=119, 84.4%. Nail involvement was seen in 17.7% (n=25 of the patients and it was observed in all subjects with DIP predominant arthritis (100%. Family history of psoriasis was present in 11.3% (n=16 of the patients. The number of patients positive for HLA B27 was 16 (11.3%. Additionally, the antigen positivity was noted in 35.7% (n=10 of the patients with spondyloarthropathy. ConclusionPs A was more common in males. Polyarthritis and oligoarthritis were the most prevalent subtypes. The prevalence of HLA-B27 in our study population was 11.3% and was found to be strongly associated with spondyloarthropathy.

    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.

    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.

    Full Text Available Background: Surgical correction of severe proximal hypospadias represents a significant surgical challenge and single-stage corrections are often associated with complications and reoperations. 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.

    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.

    Full Text Available Nephronophthisis (NPHP is a recessive disorder of the kidney that is the leading genetic cause of end-stage renal failure in children. Egypt is a country with a high rate of consan-guineous marriages; yet, only a few studies have investigated the clinical and molecular charac-teristics of NPHP and related ciliopathies in the Egyptian population. We studied 20 children, from 17 independent families, fulfilling the clinical and the ultrasonographic criteria of NPHP. Analysis for a homozygous deletion of the NPHP1 gene was performed by polymerase chain reaction on the genomic DNA of all patients. Patients were best categorized as 75% juvenile NPHP, 5% infantile NPHP, and 20% Joubert syndrome-related disorders (JSRD. The mean age at diagnosis was 87.5 + 45.4 months, which was significantly late as compared with the age at onset of symptoms, 43.8 ± 29.7 months (P <0.01. Homozygous NPHP1 deletions were detected in six patients from five of 17 (29.4% studied families. Our study demonstrates the clinical phenotype of NPHP and related disorders in Egyptian children. Also, we report that homozygous NPHP1 deletions account for 29.4% of NPHP in the studied families in this cohort, thereby confirming the diagnosis of type-1 NPHP. Moreover, our findings confirm that NPHP1 deletions can indeed be responsible for JSRD.

    We report the first case series from Africa and the Middle East on choledochal cyst, a disease which shows significant geographical distribution with high incidence in the Asian population. 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.

    Full Text Available Bruno C Silva, Camila E Rodrigues, Regina CRM Abdulkader, Rosilene M Elias Nephrology Division, Hospital das Clínicas, University of São Paulo, São Paulo, Brazil Background: Nephrologists have increasingly participated in the conversion from temporary catheters (TC to tunneled-cuffed catheters (TCCs for hemodialysis. 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. No differences were observed when comparing vancomycin and cefazolin as prophylactic antibiotics on 90-day infection-free TCC survival in a Kaplan–Meier model (log-rank = 0.188. TCC removal for low blood flow occurred in 8.9% of procedures. Conclusion: Conversion of TC to TCC by nephrologists had overall infection, catheter patency, and complications similar to data reported in the literature. Vancomycin was not superior to cefazolin as a prophylactic antibiotic.

    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.

    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.

    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 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.

    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.

    Full Text Available Objective: Non-Hodgkin’s lymphoma (NHL of bone is a rare entity. The most common histological subtype is diffuse large B cell lymphoma (DLBCL. The major presenting symptoms are soft tissue swelling, bone pain and pathological fracture. Treatment options are chemotherapy, radiotherapy, surgery, or a combination of these modalities. Materials and Methods: We retrospectively analyzed the 18 patients (11 females, 7 males with NHL of bone who were diagnosed and treated between 1995-2005. The median age was 56.5 years. The median duration of symptoms was 4.5 months. The bone pain was the first symptom in all patients. Tru-cut biopsy was performed for diagnosis in most of the cases. Diagnosis in five patients (27.8% required open biopsy. Results: DLBCL (77.8% was the most common histological type among all patients. Other histological subtypes were anaplastic large cell lymphoma (11.1%, Burkitt-like lymphoma (5.6% and marginal zone lymphoma (5.6%. According to Ann Arbor staging system, 44.4% of patients were Stage I, 11.1% were Stage II and 44.4% were Stage IV. Bone marrow involvement was determined in four patients (22.2%. All patients except one were treated with anthracycline-containing regimens and eight patients (44.4% received rituximab combination with chemotherapy. Radiation therapy was performed as the first-line therapy in 9 (50% patients. The median follow-up was 37 months (range, 2-124 months. Among the 17 patients who achieved complete remission, five (27.8% relapsed. All patients were still alive. The five-year relapse-free survival was 73.5%.Conclusion: The treatment of bone lymphoma can be planned according to the stage and location of the disease. Although we had a relatively low number of patients, it could be concluded that whether or not radiation therapy is performed, rituximab in combination with systemic chemotherapy has been proven beneficial on survival.

    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.)

    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.

    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 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 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.

    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

    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.

    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.

    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.

    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.

    Background:Although primary hypophysitis is not uncommon,a granulomatous etiology of hypophysitis is relatively rare.Radiological and diagnostic characteristics of several isolated cases have been described to date.However,to the best of our knowledge,surgical treatment of eight cases of granulomatous hypophysitis confirmed by histopathology has not yet been reported.Methods:A retrospective study was performed to review cases of granulomatous hypophysitis from November 2003 to November 2013 in our neurosurgical department.Only eight out of 1345 operations were diagnosed with granulomatous hypophysitis.Results:The cohort included two men and six women.The most common manifestations reported were headache,fatigue and polyuria.All six female patients presented with either menstrual disorders or amenorrhea.Seven of eight patients suffered polyuria.Two patients suffered bitemporal hemianopsia.One was accompanied with eosinophilic granuloma of the skull.Prolactin levels were increased in six patients,four of them were noted to have thyroid axis imbalances,one was noted to be deficient in the gonadotropin axis and two were deficient in the adrenal axis.The lesion demonstrated homogenous enhancement and an abnormally thickened pituitary stalk.A histological diagnosis of granulomatous hypophysitis was established in all eight patients,who were treated surgically.Characteristic granulomas formed by epithelioid histiocytes and multinucleated giant cells were observed.Conclusions:Pure glucocorticoid therapy is less effective than surgical intervention and has not been recommended for the treatment of granulomatous hypophysitis.Although replacement therapy can relieve associated symptoms,we conclude surgical intervention,particularly minimally invasive surgery via a transsphenoidal approach,to be mandatory in establishing a diagnosis and reducing the size of the inflammatory mass.Adjuvant corticosteroids therapy is recommended.

    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.

    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 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.

    2014-01-01

    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.

    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.

    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.

    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.

    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.

    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.

    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 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.

    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.

    Full Text Available 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.

    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.

    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 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.

    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.

    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.

    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 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.

    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.

    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.

    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.

    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.

    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

    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%).

    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.

    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.

    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.

    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.

    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.

    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

    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.

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.

    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.

    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.

    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.

    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.

    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.

    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 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

    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.

    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.

    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.

    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.

    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.

    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

    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.

    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 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.

    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.

    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.

    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.

    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.

    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.

    2016-10-01

    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.

    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.

    Exactly 13 years ago, in April 1986, appeared the famous paper1 by Bednorz and Müller, that announced a striking discovery of high-Tc superconductivity in cuprates. Some 40'000 papers later, we are still struggling to understand the high-Tc superconductivity. Here I summarize some of the most relevant recent results and open questions by discussing the observed phenomena in a rather complex electronic phase diagram of high-Tc oxides.

    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.

    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.

    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

    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.

    To provide retrospective, descriptive information on patients with cervical necrotizing fasciitis treated at a single center during the years 1998-2014, and to evaluate the outcome of a newly introduced treatment strategy. Retrospective analysis of clinical data obtained from medical records. Mortality, pre-morbidity, severity of illness, primary site of infection, type of bacteria, time parameters. The observed 3-month mortality was 6/59 (10 %). The most common initial foci of the infection were pharyngeal, dental or hypopharyngeal. The most common pathogen was Streptococcus milleri bacteria within the Streptococcus anginosus group (66 % of the cases). Using a combined treatment with early surgical debridement combined with hyperbaric oxygen treatment, it is possible to reduce the mortality rate among patients suffering from cervical necrotizing fasciitis, compared to the expected mortality rate and to previous historical reports. Data indicated that early onset of hyperbaric oxygen treatment may have a positive impact on survival rate, but no identifiable factor was found to prognosticate outcome.

    Patients with active inflammatory bowel disease (IBD) have elevated and activated myeloid leukocytes, which infiltrate the intestinal mucosa. A significant proportion of IBD patients do not respond adequately to conventional treatment regimes. Studies have suggested that treatment with granulocyte monocyte apheresis (GMA) could be a safe and efficacious alternative for these patients. We evaluated the efficacy and safety of granulocyte/monocyte apheresis in patients with IBD in a retrospective cohort study, conducted from a single center in Stockholm. Clinical details from consecutive apheresis treated patients were retrospectively reviewed from 2004 to 2012. A total of 37 patients were included, 23 patients with ulcerative colitis (UC) and 14 with Crohn's disease (CD). Clinical response was seen in 11 patients (30%) and complete remission in 11 patients (30%). The remission rate was higher in UC patients compared to CD patients, 39% (N = 9) and 14% (N = 2) respectively. A total of 9 patients experienced adverse events. Most frequently reported was headache (N = 4). GMA seems to be a valuable adjuvant treatment regime in the care of patients with refractory IBD.

    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.

    Full Text Available Objective: To determine the economic burden of road traffic accidents (RTAs in patients admitted to a single center in south eastern Iran. Methods: This cross-sectional study was conducted in Amir-Al-Momenin hospital of Zabol affiliated with Zabol University of Medical Sciences during a 12-month period from April 2012 to April 2013. All the RTAs patients who were admitted to our emergency department were included. The direct expenses of hospital care were recorded according to their medical charts and the accountant registration information. Data are presented according to different RTAs characteristics. Results: Overall 1155 patients were included in the current study with mean age of 36.7 ± 5.14 years among whom there were 673(58.3% men and 482 (41.7% women. The annual incidence of RTAs were calculated to be 288 per 100,000 population. The RTAs economic burden in our center was 589,448.49 USD which accounted for 10.4% of total hospital expenses during the study period. The money spend on RTAs in our center was 130 times more than gross national income per capita. Cost of each patient in road traffic was 15 times more than cost of an average patient of the hospital in other sections. Conclusion: With considerable high ratio of accidents in Zabol, proper intervention is needed for controlling and preventing RTAs in order to decrease its injuries, impact and the associated economic burden.

    The incidence of surgical complications after kidney transplantation has been reported to range from 1% to 33%. The aim of this work was to report surgical urological complications among our cohort of 134 pediatric kidney transplantations. Epidemiological and clinical data of all patients younger than 18 years transplanted between January 1984 and May 2012 were collected from our prospective database. Urologic complications and management are reported herein. One hundred twenty-four patients, including 44% females underwent 134 renal transplants. Median age at the time of the surgery was 13 years. Mean time of end-stage renal disease was 25 months. We identified 10 subjects (7.5%) with urological complications: 5 ureterovesical stenoses, 2 lymphoceles, and 3 lower ureteral fistulas. All of the renal allografts were obtained from cadaveric donors. Mean age of these patients at the time of transplantation was 13 years. Mean cold ischemia time was 1613 minutes. All the patients required surgical management. All patients with ureterovesical stenoses underwent ureteral reimplantation using a Boari flap; those with lymphoceles underwent open marsupialization; 2 with ureteral fistulas underwent reimplantation of the ureter, and the other patient's case required placement of a nephrostomy tube and an antegrade ureteral catheter. All patients were treated successfully. Mean follow-up time of cases with urological complications was 9.5 years. Currently, 60% has nonfunctioning allografts; the mean current glomerular filtration rate of the functioning renal allografts is 55 mL/min. Despite requiring surgical management, all patients were treated successfully. Prompt identification and treatment of any complication are critical for graft and patient survival.

    BackgroundProstatic artery embolization (PAE) has been performed for a few years, but there is no report on PAE using the PErFecTED technique outside from the team that initiated this approach.ObjectiveThis single-center retrospective open label study reports our experience and clinical results on patients suffering from symptomatic BPH, who underwent PAE aiming at using the PErFecTED technique.Materials and MethodsWe treated 32 consecutive patients, mean age 65 (52–84 years old) between December 2013 and January 2015. Patients were referred for PAE after failure of medical treatment and refusal or contra-indication to surgery. They were treated using the PErFecTED technique, when feasible, with 300–500 µm calibrated microspheres (two-night hospital stay or outpatient procedure). Follow-up was performed at 3, 6, and 12 months.ResultsWe had a 100 % immediate technical success of embolization (68 % of feasibility of the PErFecTED technique) with no immediate complications. After a mean follow-up of 7.7 months, we observed a 78 % rate of clinical success. Mean IPSS decreased from 15.3 to 4.2 (p = .03), mean QoL from 5.4 to 2 (p = .03), mean Qmax increased from 9.2 to 19.2 (p = .25), mean prostatic volume decreased from 91 to 62 (p = .009) mL. There was no retrograde ejaculation and no major complication.ConclusionPAE using the PErFecTED technique is a safe and efficient technique to treat bothersome LUTS related to BPH. It is of interest to note that the PErFecTED technique cannot be performed in some cases for anatomical reasons.

    Full Text Available Blunt chest traumas mostly occur due to car accidents and can cause many cardiac complications such as septal rupture, free-wall rupture, coronary artery dissection or thrombosis, heart failure, arrhythmias, and chordae and papillary muscle rupture. One of the most serious complication is tricuspid regurgitation (TR, which can be simply diagnosed by physical examination and confirmed by echocardiography. We describe a 48-year-old female patient, diagnosed with severe TR 13 years after a blunt chest trauma due to a car accident. TR was diagnosed with transthoracic echocardiography and three dimensional transthoracic echocardiography had defined the exact pathology of the tricuspid valve. The patient underwent successful surgery with bioprosthetic valve implantation and was discharged at 6th postoperative day without any complication. The patient had no problem according to the follow-up one month and six months after operation

    Full Text Available Langerhans Cell Histiocytosis (LCH is a rare neoplasm characterized by abnormal proliferation of histiocytic cells. In this case report, we describe a unique case of a 13-year-old boy who presented to the clinic with an insidious onset of mid-clavicular pain. The provisional radiologic diagnosis of Langerhans Cell Histiocytosis of the clavicle was confirmed by an incisional biopsy of the left mid-clavicle lesion. The patient’s lesion was treated by curettage, bone grafting, and internal fixation, due to the presence of pathologic fracture. At the 2-year followup, the patient was asymptomatic, and the lesion showed complete resolution without recurrence. The case report highlights the characteristic features of Langerhans Cell Histiocytosis in an unusual location, the knowledge of which would help avoid delayed or missed diagnosis in the future.

    Melanoma in children, adolescents, and young adults is uncommon and reported almost exclusively as cutaneous melanoma. Melanoma presenting as a pleural effusion is very rare in adults and not reported in the pediatric population. Additionally, primary pulmonary melanoma is overall very rare and undocumented in pediatric patients. Furthermore, the distinction between a primary pulmonary/pleural melanoma versus a regressed cutaneous melanoma with pulmonary/pleural metastases remains extremely challenging. We discuss a case of a previously healthy 13-year-old girl that presented with a left-sided pleural effusion. Investigations revealed a large mediastinal mass, left-sided pleural and pulmonary nodules, a sacral mass, and bone marrow infiltration. The neoplasm was subsequently diagnosed by morphology and immunocytochemistry with histological correlation as malignant melanoma. As no mucosal, eye, or cutaneous lesions were identified, we deliberate the likelihood of a regressed cutaneous melanoma with metastases versus primary pulmonary/pleural melanoma with pleural effusion and discuss its diagnostic approach.

    Full Text Available Context: Fractures of the clavicle are one of the most common injuries to the bone in childhood, but posttraumatic nonunion of pediatric clavicle fractures are extremely rare, with only isolated reports in literature. Case Report: We report a case of a posttraumatic painful nonunion of a clavicle fracture in a 13-year-old boy that caused symptomatic compression of the external jugular vein (EJV and the formation of an arteriovenous fistula. The fracture was treated successfully with open reduction and internal fixation with a contoured recon plate 6 months following the injury. The fistula was treated by ligation and closure. Conclusion: The patient made a full recovery 6 months following surgery and was asymptomatic with full range of shoulder movement. Fracture union was confirmed by computed tomography (CT scanning and no residual fistula was found.

    How often lightning strikes the Earth has been the object of interest and research for decades. Several authors estimated different global flash rates using ground-based instruments, but it has been the satellite era that enabled us to monitor lightning thunderstorm activity on the time and place that lightning exactly occurs. Launched into space as a component of NASA s Tropical Rainfall Measuring Mission (TRMM) satellite, in November 1997, the Lighting Imaging Sensor (LIS) is still operating. LIS detects total lightning (i.e., intracloud and cloud-to-ground) from space in a low-earth orbit (35deg orbit). LIS has collected lightning measurements for 13 years (1998-2010) and here we present a fully revised and current total lightning climatology over the tropics. Our analysis includes the individual flash characteristics (number of events and groups, total radiance, area footprint, etc.), composite climatological maps, and trends for the observed total lightning during these 13 years. We have identified differences in the energetics of the flashes and/or the optical scattering properties of the storms cells due to cell-relative variations in microphysics and kinematics (i.e., convective or stratiform rainfall). On the climatological total lightning maps we found a dependency on the scale of analysis (resolution) in identifying the lightning maximums in the tropics. The analysis of total lightning trends observed by LIS from 1998 to 2010 in different temporal (annual and seasonal) and spatial (large and regional) scales, showed no systematic trends in the median to lower-end of the distributions, but most places in the tropics presented a decrease in the highest total lightning flash rates (higher-end of the distributions).

    Highlights: • We report the long-term results (2–4 years) with Flow Diverter Devices (FDD) from a single-center. • We recommend the use of FDD for large-neck aneurysms of the ICA syphon. • We think that more sophisticate FDD will reduce the incidence of technical adverse events. - Abstract: Objectives: Flow-Diverter Devices (FDD) are a new generation stents designed for the treatment of the intracranial aneurysms. This article reports the long-term results (2–4 years) of this treatment from a single-center. Methods: From November 2008 to January 2012, 35 patients (29 females and 6 males; mean age 53.9 y) with 39 intracranial aneurysms were treated by FDD. Five patients (14.3%) had ruptured aneurysms and 30 (85.7%) had no previous hemorrhage. The procedures were performed in 5 patients (14.3%) with SILK and in 30 (85.7%) with PED. In 3 patients FDDs were used as a second treatment after failure of previous coiling (2 cases) or stenting (one case). The 39 aneurysms were in supraclinoid ICA in 26 (66.7%), cavernous ICA in 2 (5.1%), PCoA in 4 (10.2%), MCA in 5 (12.9%), SCA in 1 (2.6%) and PICA in 1 (2.6%). The aneurysms were small (<10 mm) in 32 cases (82%), large (11–25 mm) in 6 (15.3%) and giant in 1 (2.6%). The occlusion rate according to the aneurysm location, size and neck and the complications were evaluated. Results: Peri-procedural complications included transient dysarthria (2 patients), vasospasm with acute intra-stent aggregation (one), microwire rupture (one) and failure of the stent opening (one). The follow-up was made between 24 and 62 months (mean 41 months); clinical examination and CTA were performed at 1, 3, 6 and 12 months after the procedure. The complete occlusion was confirmed by CTA and DSA. MRI with angiographic-studies was taken every year. Complete occlusion was obtained in 35 aneurysms (92.1%) and subtotal in 3 (7.9%). Complete occlusion occurred at 3 months in 24 cases (68.6%), within 3 and 6 months in 9 (25.7%). The rate and

    Full Text Available Introduction: Postoperative atrial fibrillation is the most common arrhythmia following bypasssurgery with significant morbidity, mortality and increased healthcare costs. The aim of this studyis to determine the incidence and timing of atrial fibrillation, identify the risk factors coveringpreoperative and intraoperative periods, evaluate rate of return to sinus rhythm by disharge, andexplore the impact on postoperative outcomes in a large group of patients operated in a singlecenter by a single surgeon.Patients and Methods: Between January 2011 and January 2012, 418 patients on preoperativesinus rhythm were operated for ischemic heart disease and associated complications (left ventricleaneurysm repair and ischemic mitral insufficiency in a single center, by a single surgeon.The preoperative, intraoperative and postoperative variables were studied.Results: The mean age of the patients were 61.92 ± 10.05, and 77.5% were male. Atrial fibrillationdeveloped in 68 (16.3% patients. The incidence peaked at second day. Patients with atrialfibrillation were older (p< 0.001. Gender, preoperative comorbidities, ejection fraction, left atrialdiameter, preoperative beta-blocker use, leukocyte count, type of operation and intraoperativevariables did not affect its occurence. Intensive care unit and hospital length of stay were longer(p< 0.05. 95.5% (n= 65 of patients were in normal sinus rhythm at discharge.Conclusion: Postoperative atrial fibrillation is a popular subject with unknowns and controversialresults which may lead to wrong interpretations. We believe that every center has its own risk factors related with the population of that region. Discussion will last, but simple precautions and close monitoring will help to minimizeadverse outcomes.

    Full Text Available Hintergrund: Chronische Koronarverschlüsse (chronic total occlusion, CTO werden in Salzburg bei 18,1 % der Patienten mit koronarer Herzerkrankung diagnostiziert. Die klinische Relevanz eines CTO ergibt sich aus der klinischen Symptomatik und einem validen Vitalitätsnachweis. 63,7 % der CTOs wurden im Jahr 2009 konservativ behandelt, 36,2 % einer Revaskularisation zugeführt: 18,8 % einer CABG und 17,4 % einer perkutanen Katheterintervention (PCI. Wir berichten über die Single-Center- Ergebnisse der CTO-PCI im Rahmen eines strukturierten CTO-Programms. Patienten: Insgesamt wurde über einen Zeitraum von 40 Monaten bei 75 Patienten (76 % männlich, mittleres Alter 62,4 Jahre ein CTO im Katheterlabor interveniert. 92 % wiesen eindeutige Symptome auf, ein Vitalitätsnachweis lag bei 82,3 % vor. 81,3 % der Patienten hatten eine Mehrgefäß-KHK, 42,6 % einen Infarkt und 58,6 % eine PCI in der Anamnese. Ergebnisse: Ein bilateraler Zugang wurde bei 36 % der Patienten gewählt, bei 20 % wurde zumindest ein retrograder Versuch unternommen. Die prozedurale Dauer betrug im Mittel 105 min, der mittlere Kontrastmittelverbrauch 319 ml, die mittlere Strahlendosis 3,23 gray. Die Erfolgsrate betrug insgesamt 73,3 %, die Komplikationsrate 13,3 %. Dabei handelte es sich überwiegend um keine lebensbedrohlichen Komplikationen. Sowohl bei Erfolg als auch bei Komplikationshäufigkeit war eine deutliche Lernkurve festzustellen. Schlussfolgerung: Die CTO-Rekanalisation ist bei sorgsamer Patientenauswahl eine rationale Therapieoption. Bei einem strukturierten Vorgehen und adäquater Materialauswahl kann bei einer akzeptablen Komplikationsrate bei 75 % der Patienten ein Erfolg erzielt werden. Als wesentliche Limitation des Eingriffes ist die hohe Strahlenbelastung für den Patienten anzusehen.

    Full Text Available Background and Purpose: Symptomatic intracranial hemorrhage (sICH is the most serious adverse event in stroke patients who received i.v. rt-PA and is usually associated with poor outcomes. The SEDAN score is built up to predict sICH. We aim to externally validate the SEDAN score in Thai patients from single center in the real world practice. Methods: The SEDAN score of stroke patients treated with intravenous rt-PA at Thammasat University Hospital from January 2010 to June 2012 was calculated. Patients were divided into three groups including symptomatic intracranial hemorrhage (sICH, asymptomatic intracranial hemorrhage (AsICH and no intracerebral hemorrhage (NoICH. The primary outcome of analyses was sICH. Each parameter of the SEDAN score and correlation between score and sICH were analyzed with univariate and multivariate model. Results: 295 patients (18.6% of stroke admission were treated with i.v. rt-PA. 13 patients (4.4% had sICH and 31 patients (10.4% had AsICH. Baseline blood sugar >12 mmol/l, early infarction, hyperdense cerebral artery, age >75 years-old and NIHSS ≥10(SEDAN were associated with sICH by univariate analysis (P value = 0.018, 12 mmol/l, early infarction, hyperdense cerebral artery, age >75 years-old and NIHSS ≥10 were 1.248, 2.503, 1.107, 1.532 and 1.263 respectively. Conclusions: The SEDAN score was practical to use and predictive in Thai population. Each parameter of the SEDAN score was an independent risk factor for sICH after treatment with i.v. rt-PA.

    PURPOSE: The primary objective of this study was to determine any difference in progression free survival (PFS), overall survival (OS), clinical benefit and tolerability between elderly and non-elderly patients receiving bevacizumab at recurrence for glioblastoma in a single center. PATIENTS AND METHODS: We retrospectively analyzed 32 patients with recurrent glioblastoma receiving bevacizumab (10 mg/kg every 14 days) between January 2011 and December 2013 in second line. Bevacizumab was introduced for all patients at recurrence after a treatment of first line by temozolomide. A cohort of 14 patients was older than 70 years against 18 patients were under 70 years. RESULTS: No statistically significant difference was detected in terms of PFS and OS. PFS was 2.8 months for elderly patients against 2.9 for non-elderly patients (p >0.5). OS from recurrence in elderly and non-elderly patients was respectively 4.3 and 5.5 months (p >0,5). Clinical improvement in neurological symptoms was observed in 3 of 14 elderly patients (21.1%) and 11 of 18 young patients (61.1%). A more important improvement in performance status was observed in young patients. Regarding toxicity, 3 of the 14 elderly patients experienced grade II or III hypertension. In younger patients, 5 adverse events have been observed (2 proteinuria, 1 hypertension, 1 hemorrhage and 1 anal abscess). CONCLUSION: Despite small number of patients in this retrospective study, the efficacy and safety of bevacizumab in recurrent glioblastoma appears similar in elderly and non-elderly patients. However, clinical benefit seemed to be less important in elderly patients. A prospective multicentric study integrating geriatric assessment tools and quality of life would be interesting in this patient's population.

    A number of molecular methods of gene expression analysis can approach genomic level. Among those, Serial Analysis of Gene Expression (SAGE) stands out. Unlike many other techniques, SAGE allows both qualitative and quantitative analysis of previously unknown transcripts. Over the course of the last 13 years, SAGE has became a recognized tool of large-scale gene expression profiling, being used extensively in human, animal, yeast and plant studies of various nature. A number of important adaptations was introduced both to the protocol of SAGE library construction and to the analytical algorithm employed. Moreover, some variations of the original protocol (MAGE, SADE, microSAGE, miniSAGE, longSAGE, superSAGE, deepSAGE, etc.) were derived to improve the utility of SAGE in certain conditions. Current review aims comparing the benefits and drawbacks of the techniques for high-throughput gene expression analysis (including SAGE) in a realistic, balanced manner. Issues related to modifications to the original protocol and further development of the SAGE are discussed.

  15. Changes in community mobility in older men and women. A 13-year prospective study.

    Full Text Available Community mobility, defined as "moving [ones] self in the community and using public or private transportation", has a unique ability to promote older peoples' wellbeing by enabling independence and access to activity arenas for interaction with others. Early predictors of decreased community mobility among older men and women are useful in developing health promoting strategies. However, long-term prediction is rare, especially when it comes to including both public and private transportation. The present study describes factors associated with community mobility and decreased community mobility over time among older men and women. In total, 119 men and 147 women responded to a questionnaire in 1994 and 2007. Respondents were between 82 and 96 years old at follow-up. After 13 years, 40% of men and 43% of women had decreased community mobility, but 47% of men and 45% of women still experienced some independent community mobility. Cross-sectional independent community mobility among men was associated with higher ratings of subjective health, reporting no depression and more involvement in sport activities. Among women, cross-sectional independent community mobility was associated with better subjective health and doing more instrumental activities of daily living outside the home. Lower subjective health predicted decreased community mobility for both men and women, whereas self-reported health conditions did not. Consequently, general policies and individual interventions aiming to improve community mobility should consider older persons' subjective health.

    Full Text Available Palatal swellings are rare in children and the incidence differs from that of the adult counterparts. When the palatal swellings do arise in children, they usually are palatal abscess from periapical region, and few cases like pleomorphic adenoma in young adults have also been reported. But inflammatory fibrosis of palate in children is a rare occurrence. Inflammatory fibrosis is formation of excess fibrous connective tissue in an organ or tissue, as a reparative or reactive process. This report describes an unusual case of iatrogenic inflammatory fibrosis on the palate due to extraction of tooth number 22 in a 13-year-old female patient. The patient presented with a single large well-circumscribed oval palatal swelling that was soft, fluctuant, not fixed, and nontender. Surgical excision of the lesion was done and it was sent for histopathological assessment. The biopsy showed fibrous tissue with collagen fibers, spindle shaped fibroblasts, neovascularization, RBCs, chronic inflammatory cells, and traces of salivary gland and nerve tissue.

    Full Text Available Background: During last decades it has become increasingly evident the importance of nutritional factors in the development and renovation of buccal tissues, particularly of teeth. Objective: To characterize permanent teething and its relation with nutritional factors in children between 5 and 13 years. Methods: Cross-sectional descriptive, observational study developed in a universe formed by 1003 children of Health Area II in Cienfuegos, out of which a sample of 330 children was selected. Data was collected from schools, regarding the teething age and nutritional status. Ponder and measurements were carried out. Results: The average teething age was lower for girls in both maxillary bones; teething sequence was 6,1,2,4,5,3,7 for the maxilla and 6,1,2,3,4,5,7 for the inferior maxillary bone. There was a prevalence of normal weight among girls, followed by thin and undernourished values. Among boy, there was a prevalence of obesity, overweight and normal weight in that order. Nutritional statuses of thin and undernourished were related with a delayed teething, mainly in the inferior maxillary bone. Permanent teething was delayed with regard to the national media. Conclusion: A clear relation was established between teething age and nutrition, mainly among thin and undernourished children.

    The eradication therapy of Helicobacter pylori (H. pylori) infection is still a challenge for gastroenterologists. One of the main causes of failure in H. pylori eradication is the antibiotic resistance mainly to clarithromycin. Culture from biopsies is maybe the most used method among the antimicrobial susceptibility techniques. In this study, we compared the antimicrobial susceptibility changes in children with H. pylori infection over 13 years and we confirmed that clarithromycin resistance has been increased (16% versus 26%) though with no statistically signficant value. Therefore, clarithromycin should not be used in empiric treatment of H. pylori eradication therapy in children, but its use should be limited only to children with known antimicrobial susceptibility. On the other hand, metronidazole resistance has decreased over this time period in statistically significant manner (56% versus 33%, p = 0.014). Furthermore, ampicillin resistance has been confirmed to be very rare (3% versus 0%) in children with H. pylori infection. In conclusion, in H. pylori infection, if we do not know the antibiotic susceptibility of patients, we should recommend an eradication therapy based on the local distribution of antibiotic resistance rates trying to limit the therapeutic failures.

    Full Text Available Abstract Introduction Hypomelanotic skin disorders like tuberous sclerosis and hypomelanosis of Ito that present with multiple systemic manifestations have been reported in association with childhood autism. Oculocutaneous albinism is another hypomelanotic skin disorder that rarely presents with multiple systemic manifestations. It is infrequently reported in association with childhood autism when compared to tuberous sclerosis and hypomelanosis of Ito. Case presentation This article reports a case of co-morbid childhood autism and oculocutaneous albinism in a 13-year old boy from Nigeria in Sub-Saharan Africa. Conclusion The observation in this case report and in two previous reports which documented association between oculocutaneous albinism and childhood autism both in the affected individuals and families of individuals with childhood autism, raises the question of a possible genetic and clinical association between oculocutaneous albinism and childhood autism. More family and genetic studies into the relationship between oculocutaneous albinism and childhood autism is desirable. This may provide useful clues into the etiology, prevention and management of childhood autism as well as oculocutaneous albinism.

    Full Text Available Abstract Introduction The sensation of palpitations may either be the initial or the only symptom of cardiac arrhythmia. We describe a case of an apparent clear temporal relationship between standard ibuprofen dosing and palpitations. A review of the medical literature revealed this to be, to the best of our knowledge, the first reported case of this type. Case presentation A 13-year-old Caucasian girl initially presented to our clinic with hamstring tendinitis. She was commenced on a medication regimen of paracetamol and ibuprofen. After the third ibuprofen dose, she experienced palpitations. These were associated with lower chest and/or upper abdominal discomfort, and a feeling of being hot and sweaty. Her symptoms ceased upon the cessation of ibuprofen therapy. Conclusion Cardiac arrhythmia is a potentially fatal disorder that may exhibit heart palpitations as its initial (or only symptom. The prompt recognition of the cause of the symptom can reduce mortality and morbidity associated with any underlying pathological processes. There is a need to investigate cases of recurrent palpitations so as to exclude underlying structural cardiac pathology and/or abnormal cardiac rhythm.

    Full Text Available Ammonia (NH3 plays an increasingly important role in the global biogeochemical cycle of reactive nitrogen as well as in aerosol formation and climate. We present extensive and nearly continuous global ammonia measurements made by the Atmospheric Infrared Sounder (AIRS from the Aqua satellite to identify and quantify major persistent and episodic sources as well as to characterize seasonality. We examine the 13 year period from September 2002 through August 2015 with a retrieval algorithm using an optimal estimation technique with a set of three, spatially and temporally uniform a priori profiles. Vertical profiles show good agreement (~5–15 % between AIRS NH3 and the in situ profiles from the winter 2013 DISCOVER-AQ field campaign in central California, despite the likely biases due to spatial resolution differences between the two instruments. AIRS captures the strongest consistent NH3 emissions from the anthropogenic (agricultural source regions, such as, South Asia (India/Pakistan, China, the US, parts of Europe, SE Asia (Thailand/Myanmar/Laos, the central portion of South America, as well as Western and Northern Africa. These correspond primarily to croplands with extensive animal feeding operations and fertilizer applications where a summer maximum and secondary spring maximum are reliably observable. In the Southern Hemisphere (SH regular agricultural fires contribute to a spring maximum. Regions of strong episodic emissions include Russia and Alaska as well as parts of South America, Africa, and Indonesia. Biomass burning, especially wildfires, dominate these episodic NH3 emissions.

    Full Text Available Developmental psychology studies the changes that occur to human body with age, consisting of the human body, the way of thinking, emotions, behaviour, relationships and human behaviours throughout life. Physical development has to do with changes that occur only in the human body (height, weight, changes in different organs of the body etc.. The aim of this research is to conclude the main characteristics of physical and motor development of children aged 13 years old. During the period of growing and development of organism, anthropometric and motor parameters change constantly, so that the whole body is under major adaption and changes, as we have noticed in the Primary and Lower Secondary School “Xhavit Ahmeti” in Hodonoc of Kamenica in the Republic of Kosovo. We implemented a survey with a number of 73 male students. The first measurements were performed in September (autumn measurements, while the second measurements in March (spring measurements.

    No follow-up studies exist on how minors who commit sexual homicides adjust once released back into the community. This is an important question given the extreme nature of their crimes, lack of recidivism data, and the expectation that one-half of them will be freed from prison by mid-life. Likewise, no studies exist on the role our culture's pervasive media violence plays in these offenses. This report describes a 13-year-old boy who committed a witnessed media violence-inspired sexual homicide. Follow-up information is provided on his community adjustment as an adult four years after release from prison. He had multiple indicators of brain dysfunction, and watched a "slasher" film just before committing the blitz style crime upon a female neighbor. Media violence literature is reviewed--against a backdrop of developmental abnormalities, neuropsychiatric vulnerabilities, family dysfunction, and mental illness. This case illustrates how the confluence of such variables, combined with the tinder of erotic screen violence, may lead to sexual murder.

    Among infants born at term, breastfeeding is associated with increased dietary variety in childhood. Preterm birth can limit early feeding options while simultaneously increasing risk for negative health outcomes that could benefit from dietary-based preventative measures. We assessed whether breastfeeding is associated with increased dietary variety at 1-3 years amongst children born preterm. We analyzed baseline data from two clinical trials investigating cognitive development after fatty-acid supplementation for 10-39 month-old children born before 35 weeks gestation (n = 189). At baseline, mothers reported breastfeeding history and completed a 161-item food-frequency questionnaire for their child. Dietary variety was assessed via 3 measures: (1) proportion items consumed at least once per month, (2) servings of a given item consumed relative to total monthly food servings, (3) daily probability of consuming a given item. Overall, 88% of children were ever breastfed (median duration = 89 days, range = 0-539), and 48% of children were ever exclusively breastfed (median duration = 59 days, range = 3-240). Exclusive breastfeeding duration was associated with dietary variety increases of 0.9% (95% CI = 0.1-1.7) for vegetables, 1.6% (95% CI = 0.2-3.0) for meat/fish, and 1.3% (95% CI = 0.2-2.4) for grain/starch, for each additional month of exclusive breastfeeding after adjustment for key confounders. Correspondingly, the variety of sweets consumed decreased by 1.2% (CI: -2.1, -0.3) per month of any breastfeeding after adjustment. These results are consistent with those in children born at term, and if causal, could provide additional support for exclusive breastfeeding to improve diet and health in children born preterm.

    The submarines responsible for the United Kingdom's nuclear deterrent have carried a junior doctor as their medical officer since the program's inception. The Vanguard Class of submarine carries approximately 150 men and deploys for about 3 months at a time. One of the central tenets of submarine operations is to remain undetected and as such the submarine will only surface in an emergency, which may include the evacuation of casualties. The prime reason for carriage of a medical officer is to mitigate against the need to evacuate personnel for medical reasons. We examined the medical section of the patrol reports submitted upon completion of each patrol over a 13 year period to determine both the rates of medical and dental attendance onboard and also the occurrence of potential medical threats to patrol integrity. The most common reasons for attendance were dermatological and musculoskeletal, consistent with previous studies of this population and working environment. There were few dental cases due to the high rates of dental fitness in the pre-sailing crews. Patrol threatening cases occurred at a rate of approximately 1 per 3 patrols, with acute appendicitis being the most common presentation. This progressed to evacuation at a rate of 1 per 15 patrols, with the successful onboard management in 79% of cases. The junior doctor onboard has limited monitoring equipment and formulary, no diagnostic equipment, basic surgical equipment and no opportunity to seek senior advice, and is therefore reliant on clinical judgement. Despite the limitations placed on the doctor on board these submarines they have proven to be effective in reducing the rate of medical evacuation.

    Spirometry is the most important tool in diagnosing pulmonary disease and is the most frequently performed pulmonary function test. Respiratory disease is also one of the greatest causes for morbidity and mortality on the Hopi Nation, but no specific reference equations exist for this unique population. The purpose of this study was to determine if population reference equations were necessary for these children and, if needed, to create new age and race-specific pulmonary nomograms for Hopi children. Two hundred and ninety-two healthy children, ages 4-13 years, attending Hopi Nation elementary schools in Arizona, were asked to perform spirometry for a full battery of pulmonary volumes and capacities of which the following were analyzed: forced vital capacity (FVC), forced expiratory volume in 1 sec (FEV1 ), FEV1 % (FEV1 /FVC), FEF25-75% and peak expiratory flow rate (PEFR). Spirometric data from Navajo children living in the same geographical region as the Hopi children were compared as well as spirometric data from common reference values used for other ethnic groups in the USA. Spirometry tests from 165 girls and 127 boys met American Thoracic Society quality control standards. We found that the natural log of height, body mass and age were significant predictors of FEV1 , FVC, and FEF25-75% in the gender-specific models and that lung function values all increased with height and age as expected. The predictions using the equations derived for Navajo, Caucasian, Mexican-American, African-American youth were significantly different (P ≤ 0.05) from the predictions derived from the Hopi equations for all of the variables across both genders, with the exceptions of Hopi versus Navajo FEV1 /FVC in the males and Hopi versus Caucasians FEF25-75% in the females. Thus it would appear for this population important to have specific formulae to provide more accurate reference values.

    Ammonia (NH3) plays an increasingly important role in the global biogeochemical cycle of reactive nitrogen as well as in aerosol formation and climate. We present extensive and nearly continuous global ammonia measurements made by the Atmospheric Infrared Sounder (AIRS) from the Aqua satellite to identify and quantify major persistent and episodic sources as well as to characterize seasonality. We examine the 13-year period from September 2002 through August 2015 with a retrieval algorithm using an optimal estimation technique with a set of three, spatially and temporally uniform a priori profiles. Vertical profiles show good agreement (˜ 5-15 %) between AIRS NH3 and the in situ profiles from the winter 2013 DISCOVER-AQ (DISCOVER-Air Quality) field campaign in central California, despite the likely biases due to spatial resolution differences between the two instruments. The AIRS instrument captures the strongest consistent NH3 concentrations due to emissions from the anthropogenic (agricultural) source regions, such as South Asia (India/Pakistan), China, the United States (US), parts of Europe, Southeast (SE) Asia (Thailand/Myanmar/Laos), the central portion of South America, as well as Western and Northern Africa. These correspond primarily to irrigated croplands, as well as regions with heavy precipitation, with extensive animal feeding operations and fertilizer applications where a summer maximum and a secondary spring maximum are reliably observable. In the Southern Hemisphere (SH) regular agricultural fires contribute to a spring maximum. Regions of strong episodic emissions include Russia and Alaska as well as parts of South America, Africa, and Indonesia. Biomass burning, especially wildfires, dominate these episodic NH3 high concentrations.

    Introduction Both, the renal pelvis and the ureter, are affected by developmental, reactive and neoplastic disorders, though rare in incidence. Aim This series of cases were analysed to study the clinicopathological characteristics of the common and comparatively rare lesions involving the renal pelvis and pelviureteric junction. Materials and Methods A retrospective collection of 476 nephrectomies and pelviureteric junction resections, received over a period of 13 years from 2001 to 2013 was done. The patients’ clinical details were obtained and the histopathological findings reviewed. The lesions were classified into non-neoplastic and neoplastic categories. Results Primary involvement of the renal pelvis and pelviureteric junction was seen in 105 of 476 specimens. The mean age was 54.5 years with a male to female ratio of 2.2:1. The non-neoplastic lesions accounted for 76.2% of cases with a majority being pelviureteric junction obstruction due to inflammation induced fibromuscular hypertrophy (68.6%) causing hydronephrosis. Urothelial carcinomas were encountered in 20% of the cases. A majority of the urothelial carcinomas were infiltrative (81%) and high grade (71%) tumours. Conclusion Renal pelvis, a conduit to propel urine, can be the site for numerous disorders. Non-neoplastic lesions were more common than neoplasms. Pelviureteric junction obstruction due to inflammation induced fibromuscular hypertrophy was the commonest lesion in our study. In the neoplastic category, urothelial carcinoma was most common. However, rare lesions such as hamartomatous fibroepithelial polyp, Von Brunn’s nests, flat urothelial hyperplasia and intramuscular haemangioma of upper ureter at the pelviureteric junction were encountered along with occasional cases of tuberculosis and squamous cell carcinomas.

    Full Text Available BACKGROUND: Severe malaria (SM is a major cause of death in sub-Saharan Africa. Identification of both specific and sensitive clinical features to predict death is needed to improve clinical management. METHODS: A 13-year observational study was conducted from 1997 through 2009 of 2,901 children with SM enrolled at the Royal Victoria Teaching Hospital in The Gambia to identify sensitive and specific predictors of poor outcome in Gambian children with severe malaria between the ages 4 months to 14 years. We have measured the sensitivity and specificity of clinical features that predict death or development of neurological sequelae. FINDINGS: Impaired consciousness (odds ratio {OR} 4.4 [95% confidence interval {CI}, 2.7-7.3], respiratory distress (OR 2.4 [95%CI, 1.7-3.2], hypoglycemia (OR 1.7 [95%CI, 1.2-2.3], jaundice (OR 1.9 [95%CI, 1.2-2.9] and renal failure (OR 11.1 [95%CI, 3.3-36.5] were independently associated with death in children with SM. The clinical features that showed the highest sensitivity and specificity to predict death were respiratory distress (area under the curve 0.63 [95%CI, 0.60-0.65] and impaired consciousness (AUC 0.61[95%CI, 0.59-0.63], which were comparable to the ability of hyperlactatemia (blood lactate>5 mM to predict death (AUC 0.64 [95%CI, 0.55-0.72]. A Blantyre coma score (BCS of 2 or less had a sensitivity of 74% and specificity of 67% to predict death (AUC 0.70 [95% C.I. 0.68-0.72], and sensitivity and specificity of 74% and 69%, respectively to predict development of neurological sequelae (AUC 0.72 [95% CI, 0.67-0.76].The specificity of this BCS threshold to identify children at risk of dying improved in children less than 3 years of age (AUC 0.74, [95% C.I 0.71-0.76]. CONCLUSION: The BCS is a quantitative predictor of death. A BCS of 2 or less is the most sensitive and specific clinical feature to predict death or development of neurological sequelae in children with SM.

    Individuals with low socioeconomic position have high rates of depression; however, it is not clear whether this reflects higher incidence or longer persistence of disorder. Past research focused on high-risk samples, and risk factors of long-term depression in the population are less well known. Our aim was to test the hypothesis that socioeconomic position predicts depression trajectory over 13 years of follow-up in a community sample. We studied 12 650 individuals participating in the French GAZEL study. Depression was assessed by the Center for Epidemiological Studies-Depression scale in 1996, 1999, 2002, 2005 and 2008. These five assessments served to estimate longitudinal depression trajectories (no depression, decreasing depression, intermediate/increasing depression, persistent depression). Socioeconomic position was measured by occupational grade. Covariates included year of birth, marital status, tobacco smoking, alcohol consumption, body mass index, negative life events and preexisting psychological and non-psychological health problems. Data were analyzed using multinomial regression, separately in men and women. Overall, participants in intermediate and low occupational grades were significantly more likely than those in high grades to have an unfavorable depression trajectory and to experience persistent depression (age-adjusted ORs: respectively 1.40, 95% confidence interval (CI) 1.16-1.70 and 2.65, 95% CI 2.04-3.45 in men, 2.48, 95% CI 1.36-4.54 and 4.53, 95% CI 2.38-8.63 in women). In multivariate models, the socioeconomic gradient in long-term depression decreased by 21-59% in men and women. Long-term depression trajectories appear to follow a socioeconomic gradient; therefore, efforts aiming to reduce the burden of depression should address the needs of the whole population rather than exclusively focus on high-risk groups.

    Aim: This study aimed to evaluate the demographic, clinical, laboratory properties of patients with macrophage activation syndrome and treatment outcomes. Material and Methods: The data of the patients who were diagnosed with macrophage activation syndrome secondary to systemic juvenile idiopathic arthritis between June 2013–May 2014 were evaluated by screening patient records. Results: Ten patients with macrophage activation syndrome were followed up in one year. The mean age at the time of diagnosis was found to be 7.6±4.5 years. The most common clinical finding at presentation (80%) was increased body temperature. Hepatosplenomegaly was found in half of the patients. The most common hematological finding (90%) was anemia. The mean erythrocyte sedimentation rate was found to be 71.8±36.2 mm/h, whereas it was measured to be lower (31.2±25.2 mm/h) at the time of the diagnosis of macrophage activation syndrome. Increased ferritin level was found in all of our patients (the mean ferritin level was found to be 23 957±15 525 ng/mL). Hypertriglyceridemia was found in nine patients (90%). The mean triglyceride level was found to be 397±332 mg/dL. Systemic steroid treatment was administered to all patients. Cyclosporine A was given to eight patients (80%), canakinumab was given to four patients (40%) and anakinra was given to five patients (50%). Plasmapheresis was performed in two patients. Improvement was found in all patients except for one patient. The patient in whom no improvement was observed showed a chronic course. Conclusions: The diagnosis of macrophage activation syndrome should be considered in presence of sudden disturbance in general condition, resistant high fever and systemic inflammation findings in children with active rheumatic disease. Complete recovery can be provided with early and efficient treatment in macrophage activation syndrome which develops secondary to systemic juvenil idiopathic arthritis. PMID:26884689

    Results of treatment of LBL on the St Jude’s total therapy XV study are comparable to most of the similar reported studies. Outcome of relapsing patients is extremely poor, hence there is a need to identify biologic or clinical prognostic factors including minimal residual tumor to better evaluate chemotherapy response. Steroid induced AVN, and cerebral vascular thrombosis were the main chemotherapeutic adverse events.

    Objective To update information on the clinical and microbiologic characteristics of pediatric vulvovaginitis in Korean prepubertal girls. Methods A total of 120 girls (aged 0 to 9 years) with culture-confirmed pediatric vulvovaginitis, diagnosed between 2009 and 2014, were enrolled in the study. The epidemiologic and microbiologic characteristics, and clinical outcomes were assessed. Patients with sexual precocity, as well as those who were referred for suspected sexual abuse, were excluded. Results Girls aged 4 to 6 years were at the highest risk of pediatric vulvovaginitis. Seasonal distribution indicated obvious peaks in summer and winter. Of the 120 subjects, specific pathogens were identified in the genital specimens in only 20 cases (16.7%). Streptococcus pyogenes (n=12, 60%) was the leading cause of specific vulvovaginitis. Haemophilus influenzae was isolated in one patient. No cases presented with enteric pathogens, such as Shigella or Yersinia. A history of recent upper respiratory tract infection, swimming, and bubble bath use was reported in 37.5%, 15.8%, and 10.0% of patients, respectively. Recent upper respiratory tract infection was not significantly correlated with the detection of respiratory pathogens in genital specimens (P>0.05). Of 104 patients who underwent perineal hygienic care, 80 (76.9%) showed improvement of symptoms without antibiotic treatment. Furthermore, the efficacy of hygienic care was not significantly different between patients with or without specific pathogens (P>0.05). Conclusion Specific pathogens were only found in 16.7% of pediatric vulvovaginitis cases. Our results indicate an excellent outcome with hygienic care, irrespective of the presence of specific pathogens. PMID:27004204

    AIM: To investigate thrombotic microangiopathy (TMA) in liver transplantion, because TMA is an infrequent but life-threatening complication in the transplantation field.METHODS: A total of 206 patients who underwent living-donor liver transplantation (LDLT) were evaluated, and the TMA-like disorder (TMALD) occurred in seven recipients.RESULTS: These TMALD recipients showed poor outcomes in comparison with other 199 recipients.Although two TMALD recipients successfully recovered, the other five recipients finally died despite intensive treatments including repeated plasma exchange (PE) and re-transplantation.Histopathological analysis of liver biopsies after LDLT revealed obvious differences according to the outcomes.Qualitative analysis of antibodies against a disintegrin-like domain and metalloproteinase with thrombospondin type 1 motifs (ADAMTS-13) were negative in all patients.The fragmentation of red cells, the microhemorrhagic macules and the platelet counts were early markers for the suspicion of TMALD after LDLT.Although the absolute values of von Willebrand factor (vWF) and ADAMTS-13 did not necessarily reflect TMALD, the vWF/ADAMTS-13 ratio had a clear diagnostic value in all cases.The establishment of adequate treatments for TMALD, such as PE for ADAMTS-13 replenishment or treatments against inhibitory antibodies, must be decided according to each case.CONCLUSION: The optimal induction of adequate therapies based on early recognition of TMALD by the reliable markers may confer a large advantage for TMALD after LDLT.

    PurposeThe purpose of this study was to evaluate need for antibiotic prophylaxis for radiofrequency ablation (RFA) of liver tumors in patients with no significant co-existing risk factors for infection.Materials and MethodsFrom January 2004 to September 2013, 83 patients underwent 123 percutaneous RFA procedures for total of 152 hepatocellular carcinoma (HCC) lesions. None of the patients had pre-existing biliary enteric anastomosis (BEA) or any biliary tract abnormality predisposing to ascending biliary infection or uncontrolled diabetes mellitus. No pre- or post-procedure antibiotic prophylaxis was provided for 121 procedures. Data for potential risk factors were reviewed retrospectively and analyzed for the frequency of infectious complications, including abscess formation.ResultsOne patient (1/121 (0.8 %) RFA sessions) developed a large segment 5 liver abscess/infected biloma communicating with the gallbladder 7 weeks after the procedure, successfully treated over 10 weeks with IV and PO antibiotic therapy and percutaneous catheter drainage. This patient did not receive any antibiotics prior to RFA. During the procedure, there was inadvertent placement of RFA probe tines into the gallbladder. No other infectious complications were documented.ConclusionThese data suggest that the routine use of prophylactic antibiotics for liver RFA is not necessary in majority of the patients undergoing liver ablation for HCC and could be limited to patients with high-risk factors such as the presence of BEA or other biliary abnormalities, uncontrolled diabetes mellitus, and large centrally located tumors in close proximity to central bile ducts. Larger randomized studies are needed to confirm this hypothesis.

    Aim. Large food bits can get stuck in the esophagus and must be removed by endoscopy. In some cases, this can be difficult or unsafe. We describe a new and safe treatment for such patients. Materials and Methods. 100 consecutive patients were referred to Akershus University Hospital with impacted food in the esophagus. In 36 patients (36%), the food passed spontaneously. In 59 (92%) of the remaining 64 patients, the food was removed by endoscopic intervention. In the last five patients, endoscopic removal was judged difficult or unsafe. These patients received the new treatment: one capsule Creon 10000 IU dissolved in 30 mL of Coca-Cola administered by a nasooesophageal tube four times daily for 2-3 days. Results. Of the 59 patients treated with endoscopic procedure, complications occurred in four (7%): three bleedings and one perforation of the esophagus. In five patients treated with Coca-Cola and Creon, the food had either passed or was soft after 2-3 days and could easily be removed. Conclusion. The treatment of choice of impacted food in the esophagus is endoscopic removal. In cases where this is difficult, we recommend treatment with Coca-Cola and Creon for 2-3 days before complications occur.

    To study the independent determinants of graft survival among pediatric and adolescent live donor kidney transplant recipients. Between March 1976 and March 2004, 1600 live donor kidney transplants were carried out in our center. Of them 284 were 20 yr old or younger (mean age 13.1 yr, ranging from 5 to 20 yr). Evaluation of the possible variables that may affect graft survival were carried out using univariate and multivariate analyses. Studied factors included age, gender, relation between donor and recipient, original kidney disease, ABO blood group, pretransplant blood transfusion, human leukocyte antigen (HLA) matching, pretransplant dialysis, height standard deviation score (SDS), pretransplant hypertension, cold ischemia time, number of renal arteries, ureteral anastomosis, time to diuresis, time of transplantation, occurrence of acute tubular necrosis (ATN), primary and secondary immunosuppression, total dose of steroids in the first 3 months, development of acute rejection and post-transplant hypertension. Using univariate analysis, the significant predictors for graft survival were HLA matching, type of primary urinary recontinuity, time to diuresis, ATN, acute rejection and post-transplant hypertension. The multivariate analysis restricted the significance to acute rejection and post-transplant hypertension. The independent determinants of graft survival in live-donor pediatric and adolescent renal transplant recipients are acute rejection and post-transplant hypertension.

    Since 1986 medical students at the University Children's Hospital Essen are trained as peers in a two week intensive course in order to teach basic paediatric examination techniques to younger students. Student peers are employed by the University for one year. Emphasis of the peer teaching program is laid on the mediation of affective and sensomotorical skills e.g. get into contact with parents and children, as well as manual paediatric examination techniques. The aim of this study is to analyse whether student peers are able to impart specific paediatric examination skills as good as an experienced senior paediatric lecturer. 123 students were randomly assigned to a group with either a senior lecturer or a student peer teacher. Following one-hour teaching-sessions in small groups students had to demonstrate the learned skills in a 10 minute modified OSCE. In comparison to a control group consisting of 23 students who never examined a child before, both groups achieved a significantly better result. Medical students taught by student peers almost reached the same examination result as the group taught by paediatric teachers (21,7±4,1 vs. 22,6±3,6 of 36 points, p=0,203). Especially the part of the OSCE where exclusively practical skills where examined revealed no difference between the two groups (7,44±2,15 vs. 7,97±1,87 of a maximum of 16 points, p=0,154). The majority of students (77%) evaluated peer teaching as stimulating and helpful. The results of this quantitative teaching study reveal that peer teaching of selected skills can be a useful addition to classical paediatric teaching classes.

    The role of panfungal polymerase chain reaction (PCR) assays for diagnosis of invasive fungal disease (IFD) is inadequately defined. We describe the use of an internal transcribed spacer 1 (ITS-1) region-directed panfungal PCR in this context at a tertiary referral transplant center. A retrospective review of patients at Alfred Health, Melbourne, Australia (2009-2014) who had clinical samples referred for panfungal PCR testing was conducted. Baseline patient characteristics, antifungal drug history, fungal culture/histopathology, and radiology results were recorded. For bronchoalveolar lavage (BAL) fluid samples, identification of a fungus other than a Candida spp. was defined as a potential pathogen.Of 138 panfungal PCR tests (108 patients), 41 (30%) were positive for a fungal product. Ninety-seven percent (134/138) of specimens were from immunocompromised hosts. Thirteen percent (19/138) of panfungal PCR positive results were for potential pathogens and potential pathogens were detected more frequently in tissue as compared with BAL (12/13 vs. 6/26; P = .0001). No positive panfungal PCR results were obtained from CSF specimens. If histopathology examination was negative, panfungal PCR identified a potential pathogen in only 12% (11/94) of specimens. For the 20 culture negative/histopathology positive specimens, diagnosis of IFD to causative species level by panfungal PCR occurred in 35% (6/20).Sterile site specimens, in particular tissue, were more frequently panfungal PCR positive for potential pathogens than BAL. The utility of panfungal PCR appears greatest in tissue specimens, as an adjunct to histopathology to improve diagnostic sensitivity and specificity. Based on the results of this study we are now only testing tissue specimens by panfungal PCR.

    Full Text Available Objective: Diagnostic whole body scan (pre-therapy scan with either I-123 or I-131 (radioactive isotopes of iodine is performed to assess the extent of thyroid cancer especially distant metastasis prior to administering the therapeutic dose of I-131. Our aim of the following study was to determine the utility of the diagnostic pre-therapy scan in the management of differentiated thyroid cancer. Materials and Methods: It was a case-control study carried out by retrospective chart review, of a randomly selected 100 patients with differentiated thyroid cancer who had followed in our community hospital over the course of 1 year. We collected data on multiple variables in the subjects - including age, gender, pre-operative size of the nodules, diagnosis, stage of the malignancy, size of the tumor, multifocality, lymphovascular invasion, dose of radioiodine used for remnant ablation, recurrence rates and persistence rates. Continuous variables were compared using the independent sample Mann-Whitney U-test whereas the Chi-square test was used for nominal variables. Results: The mean dose of radioactive iodine administered was 97.56 (±27.98 in the pre-therapy scan group and it was 97.23 (±32.40 in the control group. There was no difference between the two groups (P - 0.45. There was also no difference in the recurrence rates between the groups (P = 1.0. There was a trend toward a higher degree of persistent cancer in the group that had the pre-therapy scans (P - 0.086. Conclusion: Pre-therapy scan may not affect the dose of radio-iodine I-131 used for remnant ablation of differentiated thyroid cancer and does not influence the recurrence rates. This was especially true with respect to I-131 remnant ablation for low risk tumors.

    Il “body packing” è un modo di trasportare pacchetti di droga all’interno delle cavità corporee. In Europa, come ha sottolineato l’ultimo report dell’Osservatorio di Bruxelles, ci sono 74 milioni di consumatori di sostanze stupefacenti. L’Italia è in pole position e Perugia è stata considerata come una “capitale” del commercio di droga. I “body packers” usualmente ingeriscono i pacchetti contenenti la droga, sebbene in letteratura sia riportato anche il trasporto all’interno di retto o vagina. La gestione dipende dal fatto che il paziente sia o meno sintomatico. Il trattamento chirurgico è indicato in presenza di sintomi da intossicazione non controllati dal trattamento medico, in caso di evidenza radiologica della presenza degli ovuli ritenuti nella cavità gastrica, segni di ostruzione o perforazione intestinale. È inoltre importante sottolineare che, in un contesto multidisciplinare, la gestione del paziente sintomatico che deve essere portato in sala operatoria è mirata alla stabilizzazione dei parametri vitali ed in genere viene demandata ai medici della Terapia Intensiva. In questo lavoro presentiamo l’esperienza del nostro centro con la gestione dei “body packers” sia chirurgica che conservativa.

    Many adults with epilepsy have breakthrough seizures despite treatment with antiepileptic drugs (AEDs), requiring them to have a rescue medication as part of a comprehensive treatment plan. We evaluated the effectiveness and tolerability of rectal diazepam in the treatment of breakthrough seizures in adult patients with epilepsy. We identified 50 such patients who had used diazepam rectal gel for clusters of seizures defined as acute repetitive seizures, prolonged seizures, or both, in the previous 18 months. Information on diagnoses, dose, frequency of use, reasons for use, safety, and efficacy was collected. Diazepam rectal gel was effective in stopping seizures in 45 patients (90%). Somnolence was reported in most patients, but no other adverse events were reported. Diazepam rectal gel demonstrates efficacy and tolerability as a seizure rescue medication for adult patients with a variety of seizure types, and may help improve quality of life.

    L’ascite maligna rappresenta il quadro avanzato di anormale accumulo di liquido intraperitoneale in pazienti con carcinosi peritoneale. Questa condizione clinica può rappresentare la condizione terminale di questa patologia a pessima prognosi inficiando inoltre la qualità di vita dei pazienti. Le opzioni terapeutiche includono differenti procedure che hanno tuttavia una limitata efficacia e alcune criticità; diuretici, paracentesi, shunt veno-peritoneali, inibitori delle metallo proteasi, immunomodulatori e agenti biologici rappresentano alcuni esempi di queste procedure. Nessuno di questi approcci terapeutici rappresenta a oggi lo standard of care per questa patologia data la scarsa efficienza e l’alto grado di effetti collaterali. L’introduzione della chirurgia citoriduttiva e della chemio terapia ipertermica intraperitoneale sembra essere un approccio terapeutico valido nel trattamento dell’ascite maligna refrattaria, introdotto nelle ultime due decadi e che tutt’ora necessita di validazione scientifica. In questo lavoro condividiamo la nostra esperienza di tre casi affetti da ascite maligna refrattaria trattati con HIPEC; facciamo inoltre una revisione della letteratura.

    Objective The purpose of this study was to describe the clinical characteristics of acute transverse myelitis, including the time of their presentation, and to evaluate their effect on accrual damage in patients with systemic lupus erythematosus (SLE). Methods Patients with SLE who were hospitalized because of incident, noninfectious myelitis at our institute between January 1997 and December 2013 were identified. As a control group, we selected for each of the patients in the study group one SLE patient hospitalized at the closest date to the case due to other severe non-neuropsychiatric (NP) SLE manifestation, with no history of NP manifestations or noninfectious disease. Clinical characteristics, laboratory results, treatment, disease activity (SLEDAI-2K), and damage (SLICC/ACR-DI) were collected from medical charts at the index hospitalization and one year after hospitalization. Results Demographics and SLE characteristics, including age at SLE diagnosis and time since SLE diagnosis to hospitalization, were comparable in patients with myelitis and controls. At hospitalization, disease activity and cumulative damage were similar in both groups. Patients with myelitis received more aggressive treatment than controls. One year after hospitalization, two of the 15 patients who completed follow-up had symptom improvement without neurologic sequelae, and 13 of them had some improvement of symptoms with neurologic sequelae. Four patients died in the myelitis group, three of them of infectious diseases, and one of alveolar hemorrhage. No patient died because of myelopathy and in the control group no patient died, although three were lost during the follow-up. Disease activity and treatment did not differ between both groups. However, cumulative damage was higher among the patients with myelitis than controls (1.9 ± 0.9 vs 0.75 ± 0.9; p = 0.003). Conclusion Patients with myelitis have clinical characteristics similar to those observed in non-NP SLE and receive more aggressive treatment. Furthermore, myelitis is associated with a significant increase in accrual damage compared with severe non-NP manifestations.

    Full Text Available ABSTRACT Purpose: To evaluate the influence of prior abdominal surgery on the outcomes after robotic-assisted laparoscopic radical prostatectomy (RALP. Materials and Methods: We retrospectively analyzed patients with prostate cancer who underwent RALP between June 2012 and February 2015 at our institution. Patients with prior abdominal surgery were compared with those without prior surgery while considering the mean total operating, console, and port-insertion times; mean estimated blood loss; positive surgical margin rate; mean duration of catheterization; and rate of complications. Results: A total of 203 patients who underwent RALP during the study period were included in this study. In all, 65 patients (32% had a prior history of abdominal surgery, whereas 138 patients (68% had no prior history. The total operating, console, and port-insertion times were 328 and 308 (P=0.06, 252 and 242 (P=0.28, and 22 and 17 minutes (P=0.01, respectively, for patients with prior and no prior surgery. The estimated blood losses, positive surgical margin rates, mean durations of catheterization, and complication rates were 197 and 170 mL (P=0.29, 26.2% and 20.2% (P=0.32, 7.1 and 6.8 days (P=0.74, and 12.3% and 8.7% (P=0.42, respectively. Furthermore, whether prior abdominal surgery was performed above or below the umbilicus or whether single or multiple surgeries were performed did not further affect the perioperative outcomes. Conclusions: Our results suggest that RALP can be performed safely in patients with prior abdominal surgery, without increasing the risk of complications.

    AIM: To evaluate the safety of donors in adult living donor liver transplantation (LDLT) using the right lobe in a single liver transplantation center in China.METHODS: We investigated retrospectively 52 living donor liver resections performed from October 2003 to July 2006. All patients were evaluated by blood tests and abdominal CT. The mean donor age was 28.2±7.4years. Residual liver volume was 42.1%±4.7%. Mean operative time was 420±76.2 min; mean ICU stay, less than 36 h; mean hospital stay, 16.4±8.6 d; and mean follow-up period, 6 mo.RESULTS: There was no mortality. The overall complication rate was 40% (21 donors). Major complications included biliary leak in two, and pneumonia in 2 donors. Minor complications included mild pleural effusion in 12 donors, transient ascites in 6, mild depression in 4, intra-abdominal collections in 2,and wound infections in 1 donor. Residual liver volume did not affect the complication rate. None required reoperation. Return to pre-donation activity occurred within 5-8 wk.CONCLUSION: Right hemi-hepatectomy can be performed safely with minimal risk in cases of careful donor selection. Major complications occurred in only 7.7% of our series.

    L’escissione chirurgica endoscopica transanale video-assistita (TEVA) mediante SILSTM– Port (Single Incision Laparoscopic Surgery) si è affermata come una tecnica valida per la rimozione completa di lesioni benigne del retto non trattabili endoscopicamente e per le neoplasie maligne del retto in fase precoce. La TEVA rappresenta una valida alternativa alla escissione microchirurgica transanale (TEM), alla chirurgia transanale convenzionale ed alla resezione transaddominale. Nella nostra Unità Operativa sono state effettuate con successo 8 resezioni di voluminosi adenomi del retto impiegando la tecnica TEVA con con il SILSTM–Port. L’età media dei pazienti è stata di 51,1 anni, il BMI medio è stato di 23. Non sono state registrate complicanze post-operatorie né conversioni verso interventi resettivi maggiori per via trans-addominale. Il decorso post-operatorio dei pazienti è stato regolare. Il tempo medio di ospedalizzazione è stato di 3 giorni. I risultati della nostra esperienza, sia pure poco numerosa, in ci consentono di valutare la tecnica TEVA con SILSTM– Port più semplice da realizzare rispetto alla TEM. La metodica infatti non richiede lunghi periodi di apprendimento né l’impiego di materiale costoso come quello impiegato nella TEM.

    Full Text Available OBJECTIVES: CKD is a worldwide threat to public health. Approximately 1.8 million people are currently being treated with renal replacement therapy including hemodialysis, peritoneal dialysis and transplantation. The etiology and factors affecting the progression of chronic kidney disease to endstage renal disease (ESRD differ in industrialized and underdeveloped countries. STUDY DESIGN: The aim of the study was to investigate the etiologies of ESRD, factors affecting progression to ESRD and mortality rates of patients between 2000-2004, in Konya, a city in the Middle Anatolian region of Turkey. MATERIAL and METHODS: We included 417 end-stage renal disease patients (207 female and 210 male between 16-90 years old receiving RRT for the first time in the study. CKD was diagnosed by GFR measurement that was calculated by MDRD formula. Co-morbidity was expressed using Wright- Khan index. RESULTS: We showed that there was an increased rate of diabetic nephropathy between 2003 and 2004. The increased rate of diabetic nephropathy was found to be statistically significant in the last two years (p<0.005. There was also significant negative correlation between mortality and diastolic BP (r: -0.143, p: 0.05 and the education level of the patients (r: -0.159, p: 0.0002. There was a positive correlation between mortality and serum urea levels (r: 0.193, p: 0.0001, HD through a catheter for the first time (r: 0.140, p: 0.0006, and receiving HD by a continuous RRT modality (r: 0.163, p: 0.0001. CONCLUSION: Our study showed that advanced age, increased mean arterial BP before the first RRT, having CVD or DM as an etiology of ESRD, increased erythrocyte sedimentation rate (ESR, decreased serum albumin levels and the presence of co-morbid diseases were the main factors that affected survival of the patients.

    Neurofibromatosis type 1 (NF1) is a hereditary disorder caused by mutations in the NF1 gene. Detecting mutation in NF1 is hindered by the gene's large size, the lack of mutation hotspots, and the presence of pseudogenes.Our goal was to establish a sensitive, feasible, and comparatively economical protocol to detect NF1 mutations using blood samples.We developed a method to screen patients for mutations. Thirty-two NF1 patients from 32 unrelated families and 120 unrelated population-match controls were investigated in this study. Specific primers were designed for NF1 to avoid pseudogenes. NF1 mutations were detected by sequencing at the deoxyribonucleic acid (DNA) and complementary DNA (cDNA) levels, and multiplex ligation-dependent probe amplification (MLPA) and familial segregation analyses were used.Forty-four specific primers designed according to the NF1 structure were successfully used for polymerase chain reaction (PCR) and DNA sequencing, which was more feasible and useful than cDNA sequencing. Thirty distinct NF1 mutations were identified in 32 patients. Thirteen mutations were novel and most were frameshift mutations (33.3%). Mutations were detected at a rate of 93.8%.Our study suggests that this sensitive, feasible, and comparatively economical protocol is effective for the detection of NF1 mutations.

    The purpose of this study was to define the incidence, dynamics, and profiles of anti-human leukocyte antigen antibodies (HLA-Abs) produced after kidney transplantation and their impact on graft outcome. A total of 72 first cadaver donor kidney recipients were prospectively monitored for the development of HLA-Abs using bead-based flow-cytometry assays (One Lambda FlowPRA tests). Sixteen recipients (22.2%) developed HLA-Abs after transplantation (class I, n = 7; class I+II, n = 6; class II, n = 3), in most cases (81.25%) within the first 2 weeks posttransplantation. A strong association between alloantibody presence and delayed graft function (Chi-square = 7.659, p < 0.01), acute rejection (Chi-square = 14.504, p < 0.001), chronic rejection (Chi-square = 12.84, p < 0.001), and graft loss (Chi-square = 20.283, p < 0.001) was found. Patients with higher alloantibody titers experienced acute rejections and even early graft loss, compared with those with lower titers for whom chronic rejections were more common. Immunologic complications occurred in recipients with both donor-specific and cross-reacting groups or non-donor-specific antibodies alone. A positive correlation (Pearson correlation, 0.245; p < 0.05) between HLA class I amino acid triplet incompatibility and alloantibody production was observed, mainly resulting from immunogenic triplotypes. Given the results obtained in this study, an alloantibody testing algorithm has been designed and implemented for routine monitoring and to define optimally the alloantibody reactivity in kidney transplant recipients.

    Despite the accumulation of positive data, the role of azathioprine (AZA) in the maintenance of remission of ulcerative colitis is still controversial. We looked at the follow-up of the ulcerative colitis patients who, after responding to either steroids or cyclosporin (CsA), received AZA at our referral center for over a decade. The 39 patients (29 m/10f) were treated between 1991 and 2007. Twenty-five of them had responded to CsA, the remaining 14 to corticosteroids. AZA was usually overlapped with either of the two agents at the initial dose of 2mg/kg/day. The definitions of remission, relapse, and AZA toxicity followed commonly agreed criteria. The median duration of the AZA treatment was 14 months (<1-201). Fifty-two percent and 14%, respectively, of the CsA and the steroid responders needed surgery (overall rate=38%). The figures were 32 and 15 at the first year. The majority of the patients had 1-2 relapses often in connection with withdrawal of AZA; only 3 of these relapsers needed hospitalization. AZA caused toxicity in 16/39 (41%) patients, requiring withdrawal in 23% of the cases; leukopenia (17%) and hepatitis/cholestasis (10%) ranked first and second for frequency. All of the patients in whom AZA was stopped (or reduced) relapsed. In conclusion, the 1-year colectomy rates compare favorably with the figures reported by the literature. By contrast, the toxicity rates were higher than expected. Failure to genotype or to use escalating AZA doses can only be hypothesized as causes.

    Background The aim of our study was to evaluate the prognostic value of Charlson's weighted index of comorbidities (WIC) in patients with prolonged acute mechanical ventilation (PAMV, ventilator care ≥96 hours). Methods We retrospectively enrolled 299 Korean PAMV patients who were admitted in a medical intensive care unit (ICU) of a university-affiliated tertiary care hospital between 2008 and 2013. Survivors were defined as patients who survived for 60 days after ICU admission. Results The patients' mean age was 65.1±14.1 years and 70.6% were male. The mean ICU and hospital length of stay was 21.9±19.7 and 39.4±39.1 days, respectively. In addition, the 60-day mortality rate after ICU admission was 35.5%. The mean WIC was 2.3±1.8, with significant differences between nonsurvivors and survivors (2.7±2.1 vs. 2.1±1.7, pday survival, WIC ≥5 had statistically lower survival than WIC day mortality in PAMV patients.

    Obesity is a risk factor for the development of umbilical hernia. Open hernia closure could be challenging in obese patients leading to high rates of recurrence. The aim of this study was to investigate the effectiveness and safety of hernia patches in the management of obese patients with umbilical hernias. All the patients included in this study were managed in the department of surgery of a primary care hospital in Germany. The data of patients undergoing umbilical hernia repair within a two-year period was retrospectively reviewed. Patients managed with the PVP were included for analysis. 24 obese patients were analyzed. Small and medium size patches were used in 15 and 9 patients respectively. The median duration of surgery was 40 min and the median length of hospital stay was 4d. The mean length of follow-up was 12 ± 9 months (range: 6-30 months). The rate of recurrence was 4.1% and the rate of complication was 8.3%. Obese patients presenting with small and medium size umbilical hernias could be safely and effectively managed with prosthetic patches like the Proceed Ventral Patch. However, the limited overlap zone following hernia closure with such a patch can be an issue.

    This study analyzed the efficacy and safety of the “drip, ship, and retrieve (DSR)” approach used to improve patient access to thrombectomy for acute stroke. Methods: The study participants were 45 patients who underwent thrombectomy following intravenous tissue plasminogen activator between September 2013 and August 2015. Patients were divided into two groups according to whether they were transferred from another hospital (DSR group; n = 33) or were brought in directly (Direct group; n = 12). The two groups were compared based on their baseline characteristics, time from stroke onset to reperfusion, outcome, and adverse events. Results: There were no significant differences in baseline characteristics. Time from onset until admission to our facility was significantly shorter in the Direct group (56.9 min) than in the DSR group (163.5 min) (P <0.0001). Conversely, time from arrival at the hospital to arterial puncture was significantly shorter in the DSR group (25.0 min) than in the Direct group (109.5 min) (P <0.0001). Time from onset to reperfusion did not differ significantly between the groups. There was no significant difference in patient outcomes, with a modified Rankin scale score of 0–2 (44.8% in DSR group versus 48.7% in Direct group). Moreover, there was no difference in the incidence of adverse events. Discussion: Despite the time required to transfer patients in the DSR group between hospitals, reducing the time from arrival until commencement of endovascular therapy meant that the time from onset to reperfusion was approximately equivalent to that of the Direct group. Conclusion: Time-saving measures need to be taken by both the transferring and receiving hospitals in DSR paradigm. PMID:27432512

    Full Text Available Background: Hereditary Tyrosinemia type I (HTI is a metabolic disease caused by deficiency of fumarylacetoacetate hydrolase enzyme. Objectives: This study reports beside its clinical and biochemical presentation, the outcome of NTBC [2- (2-nitro-4-trifloro-methylbenzoyl-1, 3-cyclohexanedion] treatment of the disease and evaluates its biochemical markers in 16 pediatric Libyan patients. Patients and Methods: The diagnosis was based on presence of high tyrosine levels in blood and succinylacetone in urine. Results: The consanguinity rate was 81.2%, the median age at onset, at diagnosis and at starting treatment were 4.5, 8, and 9.5 months respectively. At presentation hepatomegaly, jaundice, rickets and high gamma glutamyl transferase (GGT were observed in 87.5% of patients. All patients had extremely high alpha fetoprotein (AFP and high alkaline phosphatase (ALP levels. Fifteen patients were treated with NTBC, normalization of PT (Prothrombine time was achieved in average in 14 days. The other biochemical parameters of liver function (transaminases, GGT, ALP, bilirubin and albumin took longer to improve and several months to be normalized. Survival rate with NTBC was 86.6%. Patients who started treatment in a median of 3 months post onset observed a fast drop of AFP in 90.6% of patients (P = 0.003. Abnormal liver function and rickets were the common presentations, GGT was an early cholestatic sensitive test. ALP was constantly high even in asymptomatic patients. Conclusions: In HT1 a faster dropping of AFP is a marker of good prognosis.

    Several reports have emphasized the risk of hepatitis B virus (HBV) reactivation in patients with lymphoproliferative disorders undergoing cytotoxic treatment. To determine the prevalence of occult B infection (OBI) in a population with chronic lymphocytic leukemia (CLL) and management with universal prophylaxis (UP) in all patients undergoing chemoimmunotherapy or targeted prophylaxis (TP) in patients experiencing seroreversion during therapy, we analyzed 397 patients with CLL from our database. The prevalence of OBI in our patients with CLL was 8.6% (34 patients). When comparing patients with OBI/CLL with those with CLL, we did not find any statistical difference among clinical-biological parameters and time dependent endpoints except for a lower peripheral blood lymphocyte count in the OBI/CLL group (p = 0.036). From 2000 to 2010 careful follow-up and TP were adopted; two out of 10 patients (20%) showed seroreversion. From June 2010 we adopted UP during and 12 months after immunosuppressive treatment in all patients with CLL with OBI; no evidence of seroreversion was detected.

    Full Text Available Background /Aim : Autoimmune hepatitis (AIH is a common cause of end-stage liver disease worldwide. It is a disease prevalent in children and adults, with female predominance and variable clinical presentations. AIH has favorable responses to steroids and immunomodulators. Diagnosis of AIH is based on clinical and laboratory criteria, as suggested by the International Autoimmune Hepatitis Group. Data on the disease pattern of AIH from the Middle East countries is scarce. Materials and Methods : In this retrospective analysis, we studied clinical and laboratory features, immunological data, radiological findings, liver biopsy findings and response to therapy in patients with AIH from the hepatology clinics of King Abdul Aziz, University Hospital, Jeddah, from 1994 to 2008. Results : We diagnosed 41 patients with AIH, and 33 were included in the analysis. The mean age was 32.3 years, with female predominance of 75.7%. De- compensated cirrhosis at presentation was found in 45.5% of the patients. Acute hepatitis was associated with significantly higher levels of the serum ALT and bilirubin (P=0.001 and P=0.03, respectively. All our patients had type 1 AIH. Treatment with prednisolone and azathioprine resulted in complete or partial remission in majority of the patients (54.8%. However, patients with advanced disease showed a poorer response to treatment (P=0.016. Six patients with poor compliance had relapse of AIH. Two patients had a flare of the disease during pregnancy, and they responded well with prednisolone. The longest follow-up was 14 years and the shortest was 2 months. Four patients died from liver disease. Conclusion : AIH patients in Saudi Arabia are likely to present with advanced disease at a young age and would have a poorer response to therapy as compared with patients in other countries worldwide.

    Full Text Available The retreatment of recurrent intracranial vertebral artery dissecting aneurysms (VADAs after stent assisted coiling (SAC has not yet been studied. The purpose of this study was to evaluate the strategies and outcomes for retreatment of recurrent VADAs after SAC.Between September 2009 and November 2013, six consecutive patients presenting with recurrent intracranial VADAs after SAC were enrolled in this study. They were all male with age ranging from 29 to 54 years (mean age, 46.2 years. The procedures of treatments and angiographic and clinical follow-up were reviewed retrospectively. Retreatment modalities were selected individually according to the characteristics of recurrence. The outcomes of retreatment were evaluated by angiographic and clinical follow-up.Six patients with recurrent intracranial VADAs after SAC were retreated, with second SAC in three patients, coil embolization, double overlapping stents placement and endovascular occlusion with aneurysm trapping in one patient, respectively. Immediate angiographic outcomes of retreatment were: complete occlusion in three patients, nearly complete occlusion in two patients, and contrast medium retention in dissecting aneurysm in one patient. All cases were technically successful. No complications related to endovascular procedures occurred. Angiographic follow-up was available in all five patients treated with second SAC or double overlapping stents, which was complete occlusion in four patients, obliteration of parent artery in one patient, showing no recurrence at 4-11 months (mean: 8.6 months. Clinical follow-up was performed in all six patients at 11-51 months after initial endovascular treatment and at 9-43 months after retreatment. The mRS of last clinical follow-up was excellent in five patients and mild disability in only one patient.Endovascular retreatment is feasible and effective for recurrent intracranial VADAs after SAC. Individualized strategies of retreatment should be enacted according to the characteristics and reasons for the recurrence.

    Hematopoietic stem cell transplantation (HSCT) is the only proven curative option for patients with hemoglobinopathies, both thalassemia and sickle cell anemia (SCA). A busulfan-based myeloablative conditioning regimen is the standard of care for HSCT in these patients, although increased treatment-related morbidity, including veno-occlusive disease (VOD), has been demonstrated. Thirty-eight pediatric patients, median age 8 years (range, 6 months to 22 years), suffering from hemoglobinopathy were treated at Rambam Medical Center in Haifa, Israel, between 1998 and 2011. Thirty-four patients had thalassemia major and 4 had SCA. The 38 patients underwent 40 HSCTs, 34 of which were first transplants and 6 second transplants. Most transplants (32/40) were from matched sibling donors. Sources of stem cells were peripheral blood in 30 transplants, bone marrow in 7 transplants, and cord blood in 3 transplants. All received different customized busulfan-based conditioning regimens tailored by pharmacokinetic analysis of busulfan levels. Primary engraftment occurred in 37 of 40 transplants. Neutrophil engraftment (>.5 × 10(9)/L) occurred at a median of 15.3 days post-transplantation (range, 10 to 45). Platelet transfusion independence (>20 × 10(9)/L) occurred at a median of 22.3 days (range, 11 to 60). The rate of 5-year overall survival for thalassemia patients after first transplantation was 90.5% ± 5.3%. The rate of 5-year thalassemia-free survival was 81.7% ± 6.8%. Cumulative incidence of acute graft-versus-host disease (GVHD) was 17.6%. Rate of grades III to IV GVHD was 8.8%. Cumulative incidence of chronic GVHD was 23.5%, with 11.8% incidence of extensive chronic GVHD. One patient developed VOD. Full donor chimerism occurred in 36.4% of patients with class 1 + 2 thalassemia, compared with 78.6% in class 3 thalassemia (P = .049). Overall survival above 90% in patients undergoing their first transplant was demonstrated using busulfan-based conditioning regimens. The low incidence of VOD was probably due to busulfan area under the curve measurements and dose adjustment.

    The dual microcatheter technique is common practice for coil embolization of a wide-necked aneurysm, due to safety and efficacy. However, technical limitations of some complex configurations may necessitate additional microcatheters to bolster coil stability, compact the coil, or for protection. Described herein is a triple microcatheter technique for endovascular management of wide-necked intracranial aneurysms. Data accruing prospectively between January 2006 and October 2014 on simultaneously executed triple microcatheter coil embolization procedures done in 38 saccular aneurysms were reviewed. Clinical and morphological outcomes were assessed, with emphasis on technical aspects of treatment. The triple microcatheter technique was successfully applied to all 38 saccular aneurysms, involving the posterior communicating artery (n = 13), the middle cerebral artery (n = 10), the basilar tip (n = 7), the anterior cerebral artery (n = 5), and the internal carotid artery (n = 3). Stent protection was added in four patients and balloon remodeling in one. Dual microcatheters (n = 24) were usually deployed to deliver the coil within sacs of aneurysms, with the additional microcatheter used for protection. Otherwise, triple microcatheters were deployed for coil delivery (n = 11) or coils were delivered via a single microcatheter, with dual microcatheters deployed for protection (n = 3). Successful occlusion of aneurysms was achieved in 89.5% of cases, with no procedure-related morbidity or mortality. Stable occlusion was maintained in 72.2% (26/36) of the aneurysms at the final follow-up (mean interval, 30.2 ± 22.7 months). The outcomes of this limited study suggest that the triple microcatheter technique may be an effective and safe therapeutic option for wide-necked aneurysms, using technical strategies tailored to complex angio-anatomic configurations.

    OBJECTIVE Cranioplasty is a reconstructive procedure used to restore skull anatomy and repair skull defects. Optimal skull reconstruction is a challenge for neurosurgeons, and the strategy used to achieve the best result remains a topic of debate, especially in pediatric patients for whom the continuing skull growth makes the choice of material more difficult. When the native bone flap, which is universally accepted as the preferred option in pediatric patients, is unavailable, the authors' choice of prosthetic material is a polymethylmethacrylate (PMMA) implant designed using a custom-made technique. In this paper the authors present the results of their clinical series of 12 custom-made PMMA implants in pediatric patients. METHODS A retrospective study of the patients who had undergone cranioplasty at Gaslini Children's Hospital between 2006 and 2013 was conducted. A total of 12 consecutive cranioplasties in 12 patients was reviewed, in which a patient-specific PMMA implant was manufactured using a virtual 3D model and then transformed into a physical model using selective laser sintering or 3D printing. All patients or parents were administered a questionnaire to assess how the patient/parent judged the aesthetic result. RESULTS Patient age at craniectomy ranged from 5 months to 12.5 years, with a mean age of 84.33 months at cranioplasty. The mean extension of the custom-made plastic was 56.83 cm(2). The mean time between craniectomy and cranioplasty was 9.25 months. The mean follow-up duration was 55.7 months. No major complications were recorded; 3 patients experienced minor/moderate complications (prosthesis dislocation, granuloma formation, and fluid collection). CONCLUSIONS In this patient series, PMMA resulted in an extremely low complication rate and the custom-made technique was associated with an excellent grade of patient or parent satisfaction on long-term follow up.

    Full Text Available Objective: The objective of this study was to compare robotic-prostatectomy plus adjuvant radiation therapy (RPRAT versus primary RT for high-risk prostate cancer (HRPCa. Materials and Methods: A retrospective chart review was performed for the HRPCa patients treated in our institution between 2000 and 2010. One hundred and twenty-three patients with high-risk disease were identified. The Chi-square test and Fisher′s exact test were used to compare local control and distant failure rates between the two treatment modalities. For prostate-specific antigen comparisons between groups, Wilcoxon rank-sum test was used. Results: The median follow-up was 49 months (range: 3-138 months. Local control, biochemical recurrence rate, distant metastasis, toxicity, and disease-free survival were similar in the two groups. Conclusions: Primary RT is an excellent treatment option in patients with HRPCa, is equally effective and less expensive treatment compared with RPRAT. A prospective randomized study is required to guide treatment for patients with HRPCa.

    The aim of this study was to evaluate the safety and efficacy of SEAL aortic stent-graft for abdominal aortoiliac aneurysms. Between October 2007 and January 2014, 33 patients with abdominal aortoiliac aneurysms were treated with SEAL aortic stent-graft. We evaluated the technical success rate, clinical and CT follow-up periods, major complications, need for additional interventional treatment, aneurysm-related mortality and clinical success rate. SEAL bifurcated aortic stent-graft was successfully placed in 32 patients (97%). Clinical and CT follow-up periods were 24 and 14 months, respectively. Endoleak developed in 13 patients (41%): spontaneous regression or decrease in 6, need for additional treatment in 4 and follow-up loss in 3. Significant stenosis of stent-graft occurred in 4 patients (12%) and was treated with stenting in 3. Migration of stent-graft was noted in 3 patients (9%) and treated with additional stent-grafting. Aneurysm-related mortality was 9% (3 of 33). The placement of SEAL stent-graft was effective in 26 patients (79%). The placement of SEAL aortic stent-graft was safe and effective in patients with aneurysms of abdominal aorta and iliac arteries. However, complicating endoleaks, stenosis and migration of the stent-graft developed during the follow-up. Therefore, regular CT follow-up seems to be mandatory.

    Full Text Available Aim. Large food bits can get stuck in the esophagus and must be removed by endoscopy. In some cases, this can be difficult or unsafe. We describe a new and safe treatment for such patients. Materials and Methods. 100 consecutive patients were referred to Akershus University Hospital with impacted food in the esophagus. In 36 patients (36%, the food passed spontaneously. In 59 (92% of the remaining 64 patients, the food was removed by endoscopic intervention. In the last five patients, endoscopic removal was judged difficult or unsafe. These patients received the new treatment: one capsule Creon 10000 IU dissolved in 30 mL of Coca-Cola administered by a nasooesophageal tube four times daily for 2-3 days. Results. Of the 59 patients treated with endoscopic procedure, complications occurred in four (7%: three bleedings and one perforation of the esophagus. In five patients treated with Coca-Cola and Creon, the food had either passed or was soft after 2-3 days and could easily be removed. Conclusion. The treatment of choice of impacted food in the esophagus is endoscopic removal. In cases where this is difficult, we recommend treatment with Coca-Cola and Creon for 2-3 days before complications occur.

    Full Text Available Introduction: The aim of this study was to evaluate patients with end stage renal failure (ESRD who underwent chronic peritoneal dialysis (CPD. The clinical outcomes of laparoscopic and open placements of catheters were compared. Materials and Methods: We reviewed 49 (18 male and 31 female children with CPD according to age, sex, cause of ESRD, catheter insertion method, kt/V rate, complications, presence of peritonitis, catheter survival rate between January 2002 and February 2014. Results: Thirty-three patients were with open placement and 16 patients were with laparoscopic placement. The rate of the peritonitis is significantly less in patients with laparoscopic access than open access (n = 4 v sn = 25 (P<0.01. Patients with peritonitis were younger than those who had no attack of peritonitis (10.95 ± 0.8 years vs 13.4 ± 0.85 years. According to the development of complications, significant difference has not been found between the open (n = 9 and laparoscopic (n = 3 approaches except the peritonitis. Catheter survival rate for the first year was 95%, and for five years was 87.5%. There was no difference between open and laparoscopic group according to catheter survival rate. The mean kt/V which indicates the effectiveness of peritoneal dialysis was mean 2.26 ± 0.08. No difference was found between laparoscopic and open methods according to kt/V. Conclusion: Laparoscopic placement of CPD results in lower peritonitis rate. Catheter survival rate was excellent in both groups. Single port laparoscopic access for CPD catheter insertion is an effective and safe method.

    Pediatric oncology patients are often iron overloaded, due to the multiple blood transfusions necessary during the course of chemotherapy. Our aim is to report the efficacy and safety of deferasirox, an oral iron chelator, in this patient group. Deferasirox was administered to 13 children with malignancies in remission and iron overload. Ferritin, blood urea nitrogen, creatinine, transaminases, and bilirubin were recorded at 4- to 8-week intervals, and hepatic and cardiac iron overload were assessed with magnetic resonance imaging before initiation of treatment. Deferasirox was administered for an average of 6 months (SD=4.5; range, 0.3 to 18.2). Two children presented with skin rash, 1 with gastrointestinal disturbances, and 1 with fully reversible acute renal failure. The mean monthly rate of change in ferritin levels was -10.8 μg/L before initiation of treatment (95% confidence interval [CI], -19.8 to -1.8; P=0.02) and -93.6 μg/L during deferasirox treatment (95% CI, -118.1 to -69.1; PDeferasirox was effective in reducing the iron burden. The adverse effects were easily monitored and managed. Further studies are warranted to investigate the effect of deferasirox on mortality and morbidity in this population.

    Full Text Available Introduction: There are multiple techniques for surgical correction of vesicoureteral reflux (VUR. We compared the outcomes of extravesical versus Cohen′s reimplantation for VUR in children. Methods: Records of all children (n = 118 who underwent reimplantation for VUR between 2003 and 2014 were analyzed (male: female = 43:75. Children with secondary VUR, duplication anomalies, and ectopic ureter were excluded from our study. Extravesical reimplantation (EVR was performed bilateral in 32 children (Group 1a and unilateral in 19 (Group 1b, while bilateral Cohen′s reimplantation was performed in 67 (Group 2. Parameters compared were length of the surgical procedure, average duration of stay in the hospital, postoperative bladder spasms, significant hematuria >72 h, and long-term complications. Results: The mean age at operation was 15 months in Group 1, and 36 months in Group 2. The mean duration of surgery was significantly less (P = 0.0001 in Group 1a (n = 32; mean 104 min; standard deviation [SD] 18 min compared to Group 2 (n = 67; mean 128 min; SD 15 min. The mean (SD postoperative stay was significantly lower (P = 0.0001 at 4.5 (1.5 days in Group 1a compared to 6.5 (0.5 days in Group 2. Postoperative bladder spasms were significantly lower (P = 0.03 at 10/32 in Group 1a compared to 37/67 in Group 2. All patients responded well with anticholinergics. Postoperative hematuria and bladder spasms were significantly lower (P = 0.03 in Group 1a compared to Group 2. There was no significant difference in persistent VUR between Group 1 and Group 2. At 1 year follow, none of them had any evidence of ureteral obstruction. Conclusions: EVR has lower operative time, less postoperative discomfort and shorter hospital stay compared to Cohen′s reimplantation. Both techniques are equally effective in treating reflux.

    BACKGROUND: Rapidplasmaregainpositiveand/ortreponema pallidum hemagglutination negative [RPR(+)/TPHA(-)] results were designated as biologic false-positive (BFP). There are limited data about BFP reactions against syphilis in patients with hepatitis C virus (HCV) infection. This study aimed to determine the prevalence of BFP reactions for syphilis in patients with HCV infection in a large sample and assess the relationship between BFP reactions and HCV infection. METHODS:  A total of 2656 patients with positive anti-HCV and 5600 healthy control subjects were enrolled in this study. Hepatitis C serology was determined by a second generation ELISA test for HCV antibody. Syphilis serology was determined by the RPR test. Those subjects with reactive RPR positive underwent the TPHA test. Demographics and laboratory data were collected by trained clinicians. RESULTS: Among 2656 patients, 111 (4.2%) had a reactive RPR test. Of the 111 patients who were subjected to reactive RPR test, 30 (27.0%) showed HCV(+)/RPR(+). Of 5600 healthy controls, 80 (1.4%) had a reactive RPR test. Fourteen (17.5%) controls with HCV(-)/RPR(+) had a non-reactive TPHA test. These represented 1.1% of all HCV-positive and 0.3% of all HCV-negative subjects (P0.05). CONCLUSIONS: The data of this study demonstrate that HCV infection is associated with a false-positive RPR test. In this study BFPs were significantly more common in HCV positive patients compared to HCV-negative ones. Eosinophil abnormality can be considered as a predictor for BFP. Excessive BFPs must be considered in assessing the frequency of syphilis in a HCV-positive population and the importance of the treponemal specific serologic test should be emphasized for a diagnosis of syphilis in such population.

    Full Text Available Background : There are no Indian data of high-intensity focused ultrasound (HIFU. Being an alternative, still experimental modality, reporting short-term safety outcome is paramount. Aims : This study was aimed at to assess the safety and short-term outcome in patients with prostate cancer treated by HIFU. Settings and Design : A retrospective study of case records of 30 patients undergoing HIFU between January 2008 to September 2010 was designed and conducted. Materials and Methods : The procedural safety was analyzed at 3 months. Follow-up consisted of 3 monthly prostate-specific antigen (PSA levels and transrectal biopsy if indicated. All the patients had a minimum follow-up of 6 months. Results : A mean prostate volume of 26.9 ± 8.5 cm 3 was treated in a mean time of 115 ± 37.4 min. There was no intraoperative complication. The postoperative pain visual analogue score at day 0 was 2.1 ± 1.9 and at day 1 was 0.4 ± 0.8 on a scale of 1-10. Mean duration of perurethral catheter removal was 3.9 days. The complications after treatment were: LUTS in seven patients, stress incontinence in two, stricture in two, and symptomatic urinary tract infection in five. Average follow-up duration was 10.4 months (range, 6-20 months. Mean time to obtain PSA nadir was 6 ± 3 months with a median PSA nadir value of 0.3 ng/ml. Two patients had positive prostatic biopsy in the localized (high risk group. Conclusions : HIFU was safe in carcinoma prostate patients. The short-term results were efficacious in localized disease. The low complication rates and favorable functional outcome support the planning of further larger studies.

    In clinical practice, acidotic patients with acute cardiogenic pulmonary edema (ACPE) are commonly considered more severe in comparison with nonacidotic patients, and data on the outcome of these patients treated with noninvasive pressure support ventilation (NIV) are lacking.The present investigation was aimed at assessing whether acidosis on admission (pH < 7.35) was associated with adverse outcome in 65 consecutive patients with ACPE treated with NIV and admitted to our Intensive Cardiac Care Unit (ICCU).In our population, 28 patients were acidotic (28 of 65, 43.1%), whereas 41 patients were not (37 of 65, 56.9%). According to the Repeated Measures General Linear Model, pCO2 values significantly changed throughout the 2-h NIV treatment (P = 0.019) in both groups (P = 0001). In acidotic patients, pCO2 significantly decreased (51.9 ± 15.3 → 47.0 ± 12.8 → 44.8 ± 12.7), whereas they increased in the nonacidotic subgroup (36.8 ± 6.5 → 36.9 ± 7.2 → 37.6 ± 6.4). No difference was observed in intubation rate between acidotic (eight patients, 28.6%) and nonacidotic patients (12 patients, 32.4%) (P = 0.738). In-ICCU mortality rate did not differ between (13 patients, 35.1%) and nonacidotic patients (nine patients, 32.1%) (P = 0.801).Our data strongly suggest that in patients with severe ACPE treated with NIV, the presence of acidosis is not associated with adverse outcomes (early mortality and intubation rates) in these patients.

    Background: Computed tomography (CT)-guided fine needle aspiration (FNA) and biopsies are well-established, minimally invasive diagnostic tools for pulmonary lesions. Purpose: To analyze retrospectively the results of 1000 consecutive lung CT-guided FNA and/or core needle biopsies (CNB), the main outcome measures being diagnostic yield, and complication rates. Material and Methods: Patients considered eligible were those referred to our department for lung lesions. The choice of FNA, CNB, or both was based upon the radiologist's judgment. Diagnostic yield was defined as the probability of having a definite result by cytology/histology. Results: The study included 733 male patients and 267 female patients, with a mean (SD) age of 66.4 (11.4) years. The mean (SD) lesion size was 3.7 (2.4) cm in maximal diameter. Six hundred and forty-one (64%) patients underwent an FNA procedure, 245 (25%) a CNB, and 114 (11%) had been subjected to both. The diagnostic yield was 960/994 (96.6%); this decreased significantly with the use of CNB only (odds ratio [OR] 0.32; 95% CI 0.12 - 0.88; P = 0.03), while it increased with lesion size (OR 1.35; 95% CI 1.03 - 1.79; P = 0.03 per cm increase). In 506 patients (52.7%), a malignant process was diagnosed by cytopathology/histology. The complication rate reached 97/1000 (9.7%); complications included: hemorrhage, 62 (6.2%); pneumothorax, 28 (2.8%); hemorrhage and pneumothorax, 5 (0.5%); and hemoptysis, 2 (0.2%). It was not significantly affected by the type of procedure or localization of the lesion. The overall risk for complications was three times higher for lesions <4 cm (OR 3.26; 95% CI 1.96 - 5.42; P < 0.001). Conclusion: CT-guided lung biopsy has a high diagnostic yield using FNA, CNB, or both. The CNB procedure alone will not suffice. Complication rates were acceptable and correlated inversely with lesion size, not localization or type of procedure.

    We conducted a prospective study to assess utility of detection of antibodies to phospholipase A2receptor (PLA2R) in the serum of patients with membranous nephropathy. Seventy five patients with biopsy proven membranous nephropathy admitted between January 2011 and September 2014 were studied. Serum anti- PLA2R was tested by indirect immunofluorescence. The test was positive in 45 out of 60 patients with primary membranous nephropathy (PMN) and in none of the 15 patients with secondary membranous nephropathy, with a sensitivity of 75% and specificity of 100% for PMN. Anti PLA2R positivity also showed a significant correlation with quantum of proteinuria and negative correlation with serum albumin. This study has validated detection of serum anti PLA2R in PMN as a non invasive diagnostic tool in Indian patients.

    BACKGROUND Prolonged-release tacrolimus (Tac QD) is widely used in organ transplantation. However, the conversion from twice-daily tacrolimus (Tac BID) to Tac QD in Japan is usually done in stable patients months or years after liver transplantation. The aim of this study was to assess the early conversion of Tac QD during liver transplant hospital stay. MATERIAL AND METHODS Eighteen liver transplants (excluding pediatric) were performed during 2014-2015. All cases except 2 early-expired patients were enrolled. Our standard immunosuppression is oral Tac BID and steroid taper, and we add mycophenolate mofetil if indicated. Conversion criteria from Tac BID to Tac QD were: 1) relatively stable liver function with stable trough level by oral Tac BID, and 2) good general condition (no or well-controlled complications). We did not fix the exact conversion date because each patient's recovery was different. Dose conversion rate from Tac BID to Tac QD was set at 1:1. RESULTS The median number of conversion days after liver transplant was 27 days. Sixty-two percent of patients were converted within 4 weeks after liver transplant, and 56% were discharged from the hospital within 2 weeks after conversion. The comparison of the last week of Tac BID and the first week of Tac QD revealed that the mean tacrolimus trough level declined by 30.4%, resulting in the 26.2% tacrolimus dose increase during the first 2 weeks after conversion. Adverse events after conversion were limited, and all patients show normal liver function to date. CONCLUSIONS Early Tac QD conversion is safe and feasible, but its long-term effects need further investigation.

Data regarding the use of argon plasma coagulation (APC for treatment of patients with BE in Egypt are still limited. This article discusses the efficacy and safety of APC as a thermoablative modality in Egyptian patients with BE.Materials and methods: A total of 73 referred eligible patients with a confirmed endoscopic and histopathologic diagnosis of BE were enrolled in this study and subjected to thermoablation by high-power (hp-APC equipment at a 60 W setting until complete ablation or a maximum of five sessions and were followed up clinically and endoscopically at 3-month intervals. Computer-generated randomization allocated patients into APC-treated and control groups (n = 75, all of whom were treated with a proton pump inhibitor.Results: Minor and major complications occurred in 8 of 73 (10.95% and 1 of 73 (1.36% patients, respectively. Macroscopic ablation was achieved after one session in 37 of 73 (50.63% patients, and complete histologic ablation was confirmed after 167 sessions in 69 of 73 (94.52% patients. At 1-year follow-up, no relapses of BE or progression to EAC were observed.Conclusion: hp-APC at a medium-energy setting of 60 W in an acid-reduced environment can ablate BE effectively and safely with promising initial results.Keywords: Barrett's esophagus, argon plasma coagulation

    Intravenous immunoglobulin replacement therapy represents the standard treatment for hypogammaglobulinemia secondary to B-cell lymphoproliferative disorders. Subcutaneous immunoglobulin infusion is an effective, safe and well-tolerated treatment approach in primary immunodeficiencies but no extensive data are available on their use in secondary hypogammaglobulinemia, a frequent phenomenon occurring after treatment with anti-CD20 monoclonal antibodies in lymphoproliferative disorders. In this retrospective study we evaluated efficacy (serum IgG trough levels, incidence of infections per year, need for antibiotics) and safety (number of adverse events) of intravenous (300 mg/kg/4 weeks) versus subcutaneous (75 mg/kg/week) immunoglobulin replacement therapy in 61 patients. In addition, the impact of the infusion methods on quality of life was compared. All patients were treated with subcutaneous immunoglobulin, and 33 out of them had been previously treated with intravenous immunoglobulin. Both treatments appeared to be effective in replacing Ig production deficiency and in reducing the incidence of infectious events and the need for antibiotics. Subcutaneous immunoglobulin obtained a superior benefit when compared to intravenous immunoglobulin achieving higher IgG trough levels, lower incidence of overall infection and need for antibiotics. The incidence of serious bacterial infections was similar with both infusion ways. As expected, a lower number of adverse events was registered with subcutaneous immunoglobulin, compared to intravenous immunoglobulin, with no serious adverse events. Finally, we observed an improvement in health-related quality of life parameters after the switch to subcutaneous immunoglobulin. Our results suggest that subcutaneous immunoglobulin is safe and effective in patients with hypogammaglobulinemia associated to lymphoproliferative disorders.

    Full Text Available Peritonitis caused by Staphylococcus aureus is a serious complication of peritoneal dialysis (PD, which is associated with poor outcome and high PD failure rates. We reviewed the records of 62 S. aureus peritonitis episodes that occurred between 1996 and 2010 in the dialysis unit of a single university hospital and evaluated the host and bacterial factors influencing peritonitis outcome. Peritonitis incidence was calculated for three subsequent 5-year periods and compared using a Poisson regression model. The production of biofilm, enzymes, and toxins was evaluated. Oxacillin resistance was evaluated based on minimum inhibitory concentration and presence of the mecA gene. Logistic regression was used for the analysis of demographic, clinical, and microbiological factors influencing peritonitis outcome. Resolution and death rates were compared with 117 contemporary coagulase-negative staphylococcus (CoNS episodes. The incidence of S. aureus peritonitis declined significantly over time from 0.13 in 1996-2000 to 0.04 episodes/patient/year in 2006-2010 (p = 0.03. The oxacillin resistance rate was 11.3%. Toxin and enzyme production was expressive, except for enterotoxin D. Biofilm production was positive in 88.7% of strains. The presence of the mecA gene was associated with a higher frequency of fever and abdominal pain. The logistic regression model showed that diabetes mellitus (p = 0.009 and β-hemolysin production (p = 0.006 were independent predictors of non-resolution of infection. The probability of resolution was higher among patients aged 41 to 60 years than among those >60 years (p = 0.02. A trend to higher death rate was observed for S. aureus episodes (9.7% compared to CoNS episodes (2.5%, (p = 0.08, whereas resolution rates were similar. Despite the decline in incidence, S. aureus peritonitis remains a serious complication of PD that is associated with a high death rate. The outcome of this infection is negatively influenced by host factors such as age and diabetes mellitus. In addition, β-hemolysin production is predictive of non-resolution of infection, suggesting a pathogenic role of this factor in PD-related S. aureus peritonitis.

    Full Text Available Objective: We sought to analyze short-term clinical, echocardiographic, and hemodynamic consequences of percutaneous mitral balloon valvuloplasty (PMBV in the treatment of rheumatic mitral stenosis (MS in our clinic. Methods: We retrospectively reviewed 53 patients (49 females, 5 males; mean age 38±11 years who underwent PMBV for moderate or severe MS between January 2010 and October 2014. Procedural success was defined as the reaching a mitral valve area (MVA >1.5 cm2 and absence of grade 3 mitral regurgitation. Results: We were able to perform PMBV in 48 of 53 patients (91% and all the procedures that were completed were successful. PMBV couldn’t be performed in 3 patients due to inability to pass the mitral valve, 1 patient due to membranous obstructive vena cava and 1 patient due inability to perform septostomi. Two patients who underwent successful PMBV became symptomatic after an average of 14 months follow-up and mitral valve replacement was performed due to moderate-to-severe MS. Patients were followed for an average of 13 ± 8 months and atrial fibrillation development or embolic complications were not observed. Conclusion: Percutaneous mitral balloon valvuloplasty procedure is a safe and effective treatment approach with high success and low complication rates in experienced centers.

    Severe combined immunodeficiency (SCID), including the 'variant' Omenn syndrome (OS), represent a heterogeneous group of monogenic disorders characterized by defect in differentiation of T- and/or B lymphocytes and susceptibility to infections since birth. In the period of 25 years, between January 1986 and December 2010, a total of 21 patients (15 SCID, 6 OS) were diagnosed in Mother & Child Health Institute of Serbia, a tertiary-care teaching University hospital and a national referral center for patients affected with primary immunodeficiency (PID). The diagnoses were based on anamnestic data, clinical findings, and immunological and genetic analysis. The median age at the onset of the first infection was the 2nd month of life. Seven (33 %) patients had positive family history for SCID. Out of five male infants with T-B+NK- SCID phenotype, mutation analysis revealed interleukin-2 (common) gamma-chain receptor (IL2RG) mutations in 3 with positive X-linked family history, and Janus-kinase (JAK)-3 gene defects in the other two. Six patients had T-B-NK+ SCID phenotype and further 6 features of OS, 11 of which had recombinase-activating gene (RAG1or RAG2) and 1 Artemis gene mutations. One child with T+B+NK+ SCID phenotype as well had proven RAG mutation. One child each with T-B+NK+ SCID phenotype, CD8 lymphopenia and unknown phenotype remained without known underlying genetic defect. Of the eight patients who underwent hematopoetic stem cell transplant (HSCT) 5 survived, the other 13 died between 2 days and 12 months after diagnosis was made. Early diagnosis of SCID, before onset of severe infections, offers possibility for HSCT and cure. Education of primary-care pediatricians, in particular including awareness of the risk of using live vaccines and non-irradiated blood products, should improve prognosis of SCID in our setting.

    Full Text Available Background. Significant amounts of red blood cells (RBCs transfusions are associated with poor outcome after liver transplantation (LT. We report our series of LT without perioperative RBC (P-RBC transfusions to evaluate its influence on early and long-term outcomes following LT. Methods. A consecutive series of LT between 2006 and 2011 was analyzed. P-RBC transfusion was defined as one or more RBC units administrated during or ≤48 hours after LT. We divided the cohort in “No-Transfusion” and “Yes-Transfusion.” Preoperative status, graft quality, and intra- and postoperative variables were compared to assess P-RBC transfusion risk factors and postoperative outcome. Results. LT was performed in 127 patients (“No-Transfusion” = 39 versus “Yes-Transfusion” = 88. While median MELD was significantly higher in Yes-Transfusion (11 versus 21; P=0.0001 group, platelet count, prothrombin time, and hemoglobin were significantly lower. On multivariate analysis, the unique independent risk factor associated with P-RBC transfusions was preoperative hemoglobin (P<0.001. Incidence of postoperative bacterial infections (10 versus 27%; P=0.03, median ICU (2 versus 3 days; P=0.03, and hospital stay (7.5 versus 9 days; P=0.01 were negatively influenced by P-RBC transfusions. However, 30-day mortality (10 versus 15% and one- (86 versus 70% and 3-year (77 versus 66% survival were equivalent in both groups. Conclusions. Recipient MELD score was not a predictive factor for P-RBC transfusion. Patients requiring P-RBC transfusions had worse postoperative outcome. Therefore, maximum efforts must be focused on improving hemoglobin levels during waiting list time to prevent using P-RBC in LT recipients.

    This study aimed to determine changes in size of lumbar spinal canal and related articular structures, during dynamic MR scans acquired in symptomatic patients standing upright using a new open MR system. Forty patients (mean age 58.4 years) affected by lumbar back pain associated with claudication, referring symptoms since more than 6 months. No one underwent to previous spine surgery. MR scans were performed with a novel open 0.5-T scanner, patient supine and upright (90 ). Lumbar lordotic angle, flavum ligament thickness, herniated discs, spinal canal area, spinal canal and dural sac antero-posterior diameters, and spinal alignment were measured and compared in both supine and upright positions. Mean scanning time was 43 min. All the considered parameters showed a statistically significant difference, except for lumbar lordotic angle. Mean percentage differences moving from supine to upright were +3.9 % for lumbar lordotic angle, +15 % for flavum ligament thickness, +16.2 % for sagittal disc bulge, -10.8 % for dural sac diameter, -13.1 % for spinal canal diameter, and -15.8 % for spinal canal area. In supine position, no patient presented with spondylolisthesis; moving to upright position, four patients showed spondylolisthesis (grade I). Dynamic MR is a valuable diagnostic exam to analyze the structures involved in lumbar back pain due to spinal canal stenosis and spondylolisthesis; in supine position, relevant factors can be underestimated or hidden, becoming appreciable only patient standing upright. In this series, flavum ligament thickening presented a role comparable to disc bulge for narrowing of lumbar spinal canal. (orig.)

    Background Preoperative anxiety and stress are undoubtedly a difficult experience in patients undergoing elective surgery. These unpleasant sensations depend on several factors. The objective of this study was to evaluate the preoperative anxiety levels in a sample of Turkish population, as well as the underlying causes using the Spielberger State-Trait Anxiety Inventory (STAI anxiety) scale. Methods The study was conducted according to the Declaration of Helsinki and was approved by the local ethical committee. All participants gave written informed consent upon having received detailed information on the study. Upon entry in the study, state and trait anxiety questionnaires were completed by 186 patients scheduled for elective surgery. The influencing factors in regard to age, sex, educational status and others were also reported. Results There was a statistically significant positive correlation between state and trait anxiety scores in this Turkish population. While the most important predictive factors that affected state-STAI scores were age, sex and duration of sleep the night before surgery; educational status and age were the best predictors for determining the variation in trait-STAI scores. Conclusion The factors affecting anxiety levels in different populations might vary among different countries. Interestingly, in this sample of Turkish population, the trait anxiety levels were found to be higher from state-anxiety levels, especially in women and less educated people. Thus, doubts about operation and anesthesia are overlooked. This could be attributed to the low to intermediate life standards of people admitted to our hospital. PMID:28280304

    Full Text Available Cartilage has proven to be a favorable graft material to close tympanic membrane perforations. Objective: In this study we describe our experience with cartilage shield graft tympanoplasty in reconstruction of tympanic membrane perforations. Study Design: A retrospective review was done on 42 patients. The male to female ratio was 19:23 and the age range 11-72 years. Cases varied between Chronic Otitis Media with Dry Perforation and Ossicular Discontinuity and were treated with cartilage shield graft tympanoplasty type I or III, respectively. The corresponding author performed all operations over a period of 2 years at the department of Otolaryngology Head and Neck Surgery at King Abdullah Medical City, Makkah, Saudi Arabia. Methods: Patient and disease information were collected retrospectively and analyzed. Results: Graft take was achieved in 42 patients (100%. No statistically significant association between the postoperative pure tone average – air bone gap results and age, sex, or type of tympanoplasty was observed (p>0.05. The overall mean preoperative pure tone average – air bone gap was 27.0±10.5 dB, and it decreased to 14.9±7.0 dB 3 months postoperatively. A statistically significant improvement was observed (p<0.001. Conclusion: Excellent graft take results were achieved and hearing outcomes were satisfactory. Therefore, shield cartilage graft is a valid alternative in all tympanoplasty procedures.

    Renal transplantation has become an effective form of treatment for end-stage renal failure. Unfortunately, as a consequence of immunological and nonimmunological pathogenic mechanisms, chronic allograft nephropathy is responsible for the loss of a large proportion of kidney grafts after several years and return to dialysis. We have reported herein our 24 years of experience with second kidney transplantations. Of 1,302 kidney transplantations between January 1983 and June 2007 performed in our transplantation center, 100 were second transplantations. Kidney retransplantation was performed in 74 men and 26 women of overall mean age of 35.4 +/- 12.6 years. Cadaveric donor grafts were transplanted in 92 patients, whereas the remaining 8 were living-related donor kidneys. At 1, 5, and 10 years after kidney transplantation, patient survival rates were 100%, 96%, and 92%, respectively, whereas graft survival rates were 85%, 72%, and 53%, respectively. Immunosuppressive therapy included induction therapy with polyclonal anti-lymphocyte antibodies (ALG/ATG) or (starting from 1999) monoclonal anti CD 25 antibody. Our results demonstrated good outcomes for kidney retransplantations with allocation based on anti- HLA antibody identification together with induction immunosuppression.

    Full Text Available Tourette’s syndrome (TS is a neurodevelopmental disorder typically defined by multiple motor tics and at least one sound tic (1, beginning in childhood or in adolescence. More recently, Tourette’s syndrome has been acknowledged as a broad spectrum syndrome (2, including different comorbidities and coexisting symptoms. When beginning in early childhood TS mainly presents with attention deficit and hyperactivity disorder (ADHD and tics, when beginning in adolescence instead tics and obsessive-compulsive behavior or disorder (OCB/OCD are predominant. OCB/OCD trait is present in 60-80% of patients (3, and they are considered as thought tics (4. In many cases motor and sound tics resolve spontaneously in adulthood, though OCB/OCD generally remain. Tics often interfere with subject’s daily activities (5 affecting Quality of Life and causing Social Impairment, particularly in schooling and working. Handwriting is one of the most impaired school activity for TS patients because of the tics presence that hamper learning processes.In our clinical experience handwriting tics (HT could severely affect and condition TS subjects, but they are not often pointed out in the Literature. For this reason there are not precise data regarding the incidence of HT neither in Tourette’s syndrome patients nor in healthy population.

    Full Text Available AIM AND OBJECTIVE: The aim of this study was to determine the effectiveness and results of repair of Organic Tricuspid Valve disease. INTRODUCTION : since tricuspid valve disease most often found in association with other valve disease. Isolated tricuspid valve disease is ra re. Pattern of involvement of tricuspid valve disease shows functional (75% and primary (organic in (25%. Surgical repair of organic tricuspid valve disease often fails because of abnormal valve. This usually leads to limited options. This study examine s our experience of tricuspid valve repair with autologous pericardium for organic tricuspid valve disease. MATERIAL AND METHODS : From Jan 2014 to May 2015, 22 patients underwent repairs for organic tricuspid valve disease. The patient aged 15 to 65 years and all were in New York Heart Association (NYHA class of III or IV. All patients presented with severe tricuspid disease coexisting with other cardiac pathology, usually left - sided heart valve disease. Repair techniques included Commisurotomy, division o f secondary chordae, Glutaraldehyde treated autologous pericardial patch augmentation of tricuspid valve leaflets, anterior papillary muscle advancement etc with or without ring/suture annuloplasty. Follow - up duration was 3 to 18 months. RESULTS : No deaths or late reoperations occurred. All patients demonstrated clinical improvements on follow up. Echocardiographic studies before hospital discharge showed less than mild tricuspid regurgitation in all patients except one. CONCLUSIONS : Large majorit y of organic tricuspid valve regurgitation is repairable with acceptable early results. Tricuspid stenosis and mixed tricuspid valve disease are more challenging. In the latter group, it is a judgment call whether to accept a suboptimal result or replace t he valve

    Full Text Available Aplastic anemia (AA is a rare disease in which hematopoietic stem cells are severely diminished resulting in hypocellular bone marrow and pancytopenia. Etiology of AA includes auto immunity, toxins, infection, ionizing radiation, drugs and rare genetic disorders, but in the majority of cases no cause can be identified. In the present study we assessed response rate, survival, relapse and clonal evolution in patients with AA treated with immunosuppressive therapy.Patients with AA who received immunosuppressive therapy between May 1998 and September 2013 were included in this study. Patients with non-severe AA (NSAA were treated with cyclosporine (CsA and danazol while patients with severe AA (SAA as well as patients with NSAA who progressed to SAA after beginning of the treatment, were candidates for receiving antithymocyte globulin in addition to CsA and danazol.Among the 63 studied patients, 29 (46% had NSAA and 34 (54% had SAA. Three months after treatment, overall response was 58.6% in NSAA and 12.9% in patients with SAA. Survival of all patients at 5, 10 and 15 years were 73%, 55% and 49%, respectively. Survival rates were significantly higher in patients with NSAA compared to patients with SAA as well as in patients who responded at 6 months compared to non-responders. The relapse risk was 39.7% at 10 years. Relapse occurred in patients who discontinued the therapy more than those who continued taking CsA (p value<0.01. The risk of clonal evolution was 9.9% at 10 years and 22.8% at 15 years after treatment.This long-term retrospective study indicated that immunosuppressive therapy should be recommended to patients with AA. Also, our experience indicated that immunosuppressive therapy should not be discontinued after response to therapy in patients with both NSAA and SAA due to high risk of relapse. Low dose of CsA should be continued indefinitely.

    Zika virus (ZIKV) and chikungunya virus (CHIKV) cocirculate throughout much of the tropical Western Hemisphere; however, few cases of coinfection with these two pathogens have been reported. Herein, we describe three cases of ZIKV-CHIKV coinfection detected at a single center in Ecuador: a patient who developed symptoms on postoperative day 5 from an orthopedic procedure, a woman who had traveled to Ecuador for fertility treatment, and a woman who was admitted for Guillain-Barré syndrome and had ZIKV and CHIKV detected in serum and cerebrospinal fluid. All cases were diagnosed using a multiplex real-time reverse transcription polymerase chain reaction, and ZIKV viremia was detected as late as 16 days after symptom onset. These cases demonstrate the varied clinical presentation of ZIKV-CHIKV coinfections as well as the importance of multiplexed arboviral testing for these pathogens.

    Full Text Available Acute ischemic stroke (AIS due to thrombo-embolic occlusion in the cerebral vasculature is a major cause of morbidity and mortality in the United States and throughout the world. Although the prognosis is poor for many patients with AIS, a variety of strategies and devices are now available for achieving recanalization in patients with this disease. Here, we review the treatment options for cerebrovascular thromboembolic occlusion with a focus on the evolution of strategies and devices that are utilized for achieving endovascular clot extraction. In order to demonstrate the progression of this treatment strategy over the past decade, we will also present a single-center case series of AIS patients treated with endovascular thrombectomy.

    This single center, randomized, and controlled study aimed to compare the effectiveness and safety of polyethylene glycol electrolyte lavage (PEG-EL) solution and colonic hydrotherapy (CHT) for bowel preparation before colonoscopy. A total of 196 eligible outpatients scheduled for diagnostic colonoscopy were randomly assigned to the PEG-EL (n = 102) or CHT (n = 94) groups. Primary outcome measures included colonic cleanliness and adverse effects. Secondary outcome measures were patient satisfaction and preference, colonoscopic findings, ileocecal arrival rate, examiner satisfaction, and cecal intubation time. The results show that PEG-EL group was associated with significantly better colonic cleanliness than CHT group, fewer adverse effects, and increased examiner satisfaction. However, the CHT group had higher patient satisfaction and higher diverticulosis detection rates. Moreover, the results showed the same ileocecal arrival rate and patient preference between the two groups (P > 0.05). These findings indicate that PEG-EL is the preferred option in patients who followed the preparation instructions completely.

    Background Adult chronic idiopathic thrombocytopenic purpura (ITP) is a common hematologic disease characterized by persistent thrombocytopenia. So far, there were only a few reports on adult Chinese patients with chronic ITP. This study aimed at defining the treatment outcome and prognostic factors for chronic ITP based on a large cohort of Chinese patients followed up for over 25 years at a single center.Methods The medical records of 1791 patients aged 14 years or older who were diagnosed as having chronic ITP at our hospital from 1974 to 1999 were retrospectively analyzed.Conclusions Adult Chinese chronic ITP patients can have long-term remission after steroid therapy and splenectomies. Primary steroid refractoriness is a prognostic factor predicting poor subsequent response to a splenectomy.

    Shayer, Michael; Wylam, Hugh

    A crucial issue in the theory of science education at present is the problem of how much it is possible to generalize about steps in understanding achieved by different pupils in a given topic. Many Piagetians believe that there are qualitatively different steps followed in the same succession by all pupils: some Ausubelians believe that there is no such order, and that for each pupil the best criterion for the teacher is the pupil's present knowledge. One purpose of this study is to shed light on this issue. The study to be described made use of three inputs. The development of a technique of psychometrising Piaget by an English team based at London University provided a way of extending a study by Erickson (1977) of personal conceptual inventories to testing a sample of 200 children by a 68 item demonstrated group-test. In addition a team of curriculum developers had provided a tentative list of objectives for the teaching of Heat to Middle School students. The schools in which the study was carried out wished to know which of the objectives were more suitable for 9 or for 12 year-olds. The group-test utilized descriptors both from the Erickson study and from the list of curriculum objectives. In addition to the Heat test a Piagetian group-test (NFER, 1979) in the area of Volume and Heaviness was administered to see whether the development of concepts of Heat could be mapped onto Piagetian stages of development. Test-items in nine aspects of heat were written, with some of the experiments to be demonstrated to the class. These aspects included Conduction, Expansion, Composition of Heat, Temperature Scales, Changes of State, etc. Factor analysis of the data showed that one factor was sufficient to explain the common-factor variance of the heat scales, and that the Heat test was also unifactor with the Piagetian test. It was possible to describe Early Concrete, Late Concrete and Early Formal levels of understanding in the area of Heat and Temperature. In this
