Ureteric complications following renal transplantation: an eight years experience.

OBJECTIVES: Ureteric complications (UCs) following renal transplantation (RT) cause significant morbidity and ureteric stents are employed to bridge the vesico-ureteric anastomosis with a view to preventing these complications. The purpose of this study was to examine the incidence of UCs and outcomes following RT in both stented (STG) and non-stented groups (NSTG) of RT patients. METHODS: This is a retrospective study of a cohort of 650 consecutive RTs [STG (N=267; 41%) and NSTG (N=383; 59%)] performed over a period of 8 years, where the data were retrieved from a prospectively maintained computerised database and case-notes. RESULTS: The overall incidence of UCs was 6.5% (42/650), which consisted of ureteric obstruction (UO) in 4.3% (28) and ureteric leak (UL) in 2.2%(14) of patients. The incidence of UO was significantly high in the NSTG compared to the STG (6.3% vs.1.5%; P=0.002). However, the incidence of UL (3.4% vs.1.3%; P=0.1) and post-transplant urinary tract infection (UTI) (44% vs.41%; P=0.57) were not significantly different between the STG and NSTG groups. UO and UL were associated with significantly high incidence of UTI (P=0.001 and 0.01, respectively). All UCs were managed successfully without allograft loss. CONCLUSIONS: Routine stenting of ureteric anastomosis resulted in reduced incidence of UO without concomitant increased risk of UTI.

Validación de un test de ureasa rápido para el diagnóstico de la infección por H. Pylori / Validation of a rapid urease test for the diagnosis of helicobacter pylori infection

OBJECTIVE: Several non-commercial rapid urease tests have been designed with the objective of reducing the cost of Helicobacter Pylori infection diagnosis. The objective of the present prospective trial is to assess one of these tests, using the histologic evaluation for the presence of Helicobacter Pylori, as the standard reference of diagnosing this infection. METHODS: Patients undergoing upper endoscopy for various reasons were prospectively enrolled. Three endoscopic biopsies of the antrum and three from the corpus of the stomach were taken in every patient enrolled. The specimens were evaluated by the rapid urease test on an individual basis, comparing the results with the histology assessment of the Helicobacter Pylori status, which was considered as the standard reference for the diagnosis of the infection. RESULTS: One hundred and four patients were enrolled, of which 94 were eligible. Fifty-five patients (60.43%) were infected with Helicobacter Pylori. The sensibility and specificity of the urease test evaluated at 4 hours was 65.45% and 100% respectively. The evaluation at 24 hours of the sensibility and specificity was 83% and 94% respectively. CONCLUSIONS: The non-commercial rapid urease test is a practical, fast, and cost effective method for the detection of Helicobacter Pylori infection, and its diagnostic utility is similar to the commercial test available

The occurrence of non-O1 vibrio cholerae in non-potable water samples in Barbados

Fourteen freshwater or brackish-water samples taken from different sites were examined for the presence of Vibrio cholerae. Standard enrichment techniques, using pre-incubation in alkaline peptone water and plating on thiosulfate citrate bile sucrose agar (TCBS) followed by biochemical, physiological and morphological characterization of the isolates, revealed the presence of Vibrio cholerae at nine of the sites examined. Serotyping for type O1 only was performed. All the strains isolated were non-O1 Vibrio cholerae.
