Summary Objective To evaluate the frequency and clinical features of endemic other opportunistic infections in liver or kidney transplant recipients four centres different geographical areas Brazil. Methods Retrospective analysis medical laboratory records on recipients. Analyses were performed with spss statistical software. Results From 2001 to 2006, 1046 708 transplants registered all centres. The average age was 42 years. Among 82 (4.7%) cases infections, most frequent tuberculosis...
In recipients of liver transplantation (LT), surgical site infection (SSIs) are among the most common types occurring in first 60 days after LT. 2007, Model for End-Stage Liver Disease (MELD) scoring system was adopted as basis prioritizing organ allocation. Patients with higher MELD scores at risk developing SSIs well other health care-associated infections. However, there have been no studies comparing incidence pre-MELD era period since its adoption. Therefore, objectives this study were...
Data are scarce on the penetrance of multiple endocrine neoplasia type 1 (MEN1)-related nonfunctioning pancreatic neuroendocrine tumors (NF-PETs) and insulinomas in young MEN1 patients. A potential positive correlation between tumor size malignancy (2-3 cm, 18%; >3 43%) has greatly influenced management adults with NF-PETs.The aim study was to estimate NF-PETs, insulinomas, gastrinomas carriers.The data were obtained from a screening program (1996-2012) involving 113 patients tertiary...
Abstract Background Human homeobox genes encode nuclear proteins that act as transcription factors involved in the control of differentiation and proliferation. Currently, role these development tumor progression has been extensively studied. Recently, increased expression HOXB7 gene ( ) pancreatic ductal adenocarcinomas (PDAC) was shown to correlate with an invasive phenotype, lymph node metastasis worse survival outcomes, but no influence on cell proliferation or viability detected. In...
Development of immunity to hepatitis B virus in cirrhotic patients waiting for liver transplantation is highly desirable. Though a double-dose regimen available, little know about its effectiveness. We examined the efficacy vaccination transplantation. studied 43 who were They vaccinated with three doses 40 mg vaccine at 0, 1 and 6 months; normal dose 20 mg. Efficacy was measured based on seroconversion anti-HBs. Global response primary scheme 67.5% (29 patients). Forty-one per cent...
OBJETIVOS: Analisar o conhecimento e a opinião de estudantes medicina sobre doação transplante órgãos. MÉTODOS: Trezentos quarenta sete responderam, voluntariamente, questionário com 17 perguntas Eles foram avaliados globalmente, para verificar tendências gerais, agrupados acordo seu ano no curso médico (primeiro ao sexto), avaliar diferenças entre os períodos. Alunos do quinto sexto reunidos em um só grupo. Os resultados analisados pelo teste Qui quadrado. RESULTADOS: A intenção ser doador...
CONTEXT AND OBJECTIVE: Expanded donor criteria (marginal) grafts are an important solution for organ shortage. Nevertheless, they raise ethical dilemma because may increase the risk of transplant failure. This study compares outcomes from marginal and non-marginal graft transplantation in 103 cases liver due to chronic hepatic DESIGN SETTING: One hundred three consecutive transplantations treat disease performed Liver Transplantation Service Hospital das Clínicas da Faculdade de Medicina...
AIM:To report experience with liver resection in a select group of patients postoperative biliary stricture associated vascular injury. METHODS:From prospective database treated for benign strictures at our hospital, cases that underwent resections were reviewed.All referred after one or more attempts to repair bile duct injuries following cholecystectomy (open laparoscopic).Liver was indicated Strasberg E3/E4 (hilar stricture) lesions damage (arterial and/or portal), ipsilateral...
Occult hepatitis B virus (HBV) infection has been reported among patients with C (HCV) and hepatocellular carcinoma (HCC). Our aim was to evaluate the presence of occult HBV in HCV-related liver cirrhosis (LC) or without HCC São Paulo, Brazil. Serum tissue samples from 50 surface antigen-negative LC who underwent transplantation at University Paulo School Medicine Hospital 1993 2004 were divided into groups only (N = 33) plus 17). DNA assayed for serum paraffin-embedded (tumoral non-tumoral)...
Liver ischemia-reperfusion injury is a phenomenon presents in events like liver resections and transplantation. The restoration of blood flow may leads to local systemic injury. Several techniques have been developed order avoid or ameliorate clinical situations. application stutter reperfusion after the ischemic event (postconditioning) could alters hydrodynamics stimulates endogenous mechanisms that attenuate present study was designed evaluate potential protective effect postconditioning...
Non-alcoholic fatty liver disease (NAFLD) encompasses the whole spectrum of steatosis, non-alcoholic steatohepatitis (NASH), and NASH-related cirrhosis (NASH/Cir). Although molecular advances have been made in this field, pathogenesis NAFLD is not completely understood. The gene expression profiling associated to NASH/Cir was assessed, an attempt better characterize pathways involved its etiopathogenesis.In first step, we used cDNA microarray evaluate profiles normal (n=3) samples by...
Abstract Pentastomiasis is a rare zoonotic disease. Almost all recorded cases of human pentastomiasis had been incidental findings at autopsy. We report an unusual case mimicking liver tumor successfully treated by resection. This clinical presentation uncommon and it was probably caused pentastomid that exited its cyst migrated to the causing infarct mistaken as primary tumor. Diagnosis could not be made before surgery. first reported in Brazil.
Right superior liver resection or bisegmentectomy 7-8 is defined as the anatomical removal of segments 7 and 8 liver. According to recent reports, this type requires presence a large accessory right inferior hepatic vein drain remaining segment 6. However, anatomic studies have shown that 6 has multiple veins presenting several anastomosis with surrounding veins. Therefore, maintenance from 5 ultimately into middle can be enough assure venous drainage both segments.Describe an alternative...
Alimentary tract duplications are rare congenital malformations that may be found anywhere from mouth to anus. They usually share a common smooth muscle wall and blood supply with the adjacent bowel. Some asymptomatic but most cause problems in early childhood. Gastric account for 2% 7% of all gastrointestinal duplications. The management gastric duplication is essentially surgical. treatment choice complete excision without violation lumen whenever possible. authors report an unusual case...
