Tenchkoff

BACKGROUND: Peritoneal dialysis-associated peritonitis can uncommonly be caused by fungal infections. When they do present, they are associated with significant mortality and morbidity. We describe a case where a sample of peritoneal dialysate fluid grew Rhodotorula muciliginosa, a yeast organism present in the normal environment which has previously been reported as rarely causing peritonitis. We believe this is the first case where the Rhodotorula spp. and its origin has been identified...

INTRODUCTION: Major indications for peritoneal dialysis catheter removal include chronic exit-site infection (ESI) or tunnel infection (TI). No consensus on the optimal treatment of these infections in children exists. PATIENTS: During the last 10 years, 13 patients (7 females, mean age 56 months) on peritoneal dialysis were treated for recurrent ESI (N: 4) or TI (N: 9). Staphylococcus aureus (12 patients) and Pseudomonas aeruginosa (1 patient) were isolated. All patients had a double-cuff straight Tenchkoff catheter and underwent the shaving of the external cuff, with a new tunnel tightly adherent to the catheter, and an exit-site in the opposite abdominal region...

BACKGROUND: There is an increasing focus on improving the detection and management of patients with chronic kidney disease (CKD). Data on CKD prevalence based on population sampling are now available, but there are few data about CKD patients attending nephrology services or how such services are organized. AIM: To survey services for CKD patients nationally. METHODS: A pre-piloted questionnaire was sent to all 72 renal units in the UK, referring to the situation in June 2004...

BACKGROUND: Preformed HLA antibodies (Ab), reported as panel-reactive antibody (PRA), prolong patient waiting time for kidney transplantation. We hypothesized that rituximab (RTX) could reduce PRA via B-cell depletion. This initial study reports the safety, pharmacokinetics, and pharmacodynamics of RTX in patients with end-stage renal failure. METHODS: The study was an investigator-initiated single-dose, dose-escalation phase I trial of RTX in chronic dialysis patients (PRA >50%)...

BACKGROUND: All previous histological studies of skeletal muscles of patients with renal failure have used locomotor muscle biopsies. It is thus unclear to what degree the observed abnormalities are due to the uraemic state and how much is due to disuse. The present study was undertaken to attempt to investigate this question by examining a non-locomotor muscle (rectus abdominis) in patients with end-stage renal failure. METHODS: Biopsies from rectus abdominis were obtained from 22 renal failure patients (RFPs) undergoing surgical Tenchkoff catheter implantation for peritoneal dialysis and 20 control subjects undergoing elective abdominal surgery...

BACKGROUND: Peritoneal spread of gastrointestinal malignancies has been regarded as an incurable disease, and treatment has been aimed at short-term palliation. The use of cytoreductive surgery, including peritonectomy procedures and intraperitoneal chemotherapy, has been proposed with the intention of prolonging survival, and perhaps curing patients with peritoneal carcinomatosis from appendiceal and possibly colon cancers. A series of eight patients who have undergone this procedure at St George Hospital is presented, and the results obtained by other groups are reviewed...

We describe a one-port laparoscopic technique for assisting in Tenchkoff catheter placement and salvaging obstructed ones in patients requiring continuous ambulatory peritoneal dialysis (CAPD). This unique technique enables diagnostic laparoscopy, adhesiolysis, repositioning of catheters, and omentectomy to be performed without laparotomy. Six patients were treated. Only one 10-mm port was required, using an operating laparoscope and an instrument introduced through the working channel of the laparoscope. Adhesiolysis was performed under laparoscopic vision; omentectomy and flushing of blocked catheters were carried out extracorporeally...

We report the case of a patient on dialysis for 13 years, including continuous ambulatory peritoneal dialysis (CAPD) for 11 years, who developed sclerosing peritonitis with gross peritoneal calcification. The patient first presented with abdominal pain in January 1990, when peritoneal calcification was detected for the first time. Her symptoms settled spontaneously and 1 year later she presented with acute peritonitis and adynamic ileus. The peritonitis settled with antibiotics and Tenchkoff catheter removal, but the ileus persisted...
