UNLABELLED Detection of cholangiocarcinoma in extrahepatic bile duct strictures is a continuing challenge in clinical practice because brush cytology taken at endoscopic retrograde cholangiography has an average sensitivity of 50%. The aim of this study was to evaluate the effectiveness of dual-modality PET/CT using (18)F-FDG for noninvasive differentiation(More)
Pulmonary hypertension (PH) is common in patients with dialysis-dependent chronic kidney disease and is an independent predictor of mortality. However, specific hemodynamics of the pulmonary circulation, changes induced by hemodialysis and characterization into pre- or postcapillary PH have not been evaluated in patients with chronic kidney disease. We(More)
BACKGROUND Two modifications of the MDRD equation [the Mayo Clinic (MC) equation and Rule's refitted (RR) MDRD formula] were proposed to overcome disadvantages of the original MDRD formula to calculate glomerular filtration rate (GFR). Additionally, a correction factor for the original MDRD formula has been introduced to adapt this formula to creatinine(More)
Sir, We read with interest the detailed comparison of various creatinine-and cystatin C (Cys C)-based equations to determine GFR in patients after kidney transplantation [1]. This publication provides a comprehensive overview of the most commonly used equations and importantly, applies inulin clearance as gold standard GFR measurement. The authors conclude(More)
