Objective To evaluate catheter-related complications among self-locating and other variants of Tenckhoff catheters. Patients and Methods We studied all self-locating catheters implanted in our hospitals from May/97 to Dec/05. We extended the follow-up to Jun/05. We collected demographic data, causes of catheter withdrawal and dropping of PD. We studied data about technique and catheter related complications. Results We included 328 catheters in 285 patients. There were 258 self-locating, 55 straight and 15 curled. There was a higher rate of catheter withdrawal due to malfunction in patients with straight or pig-tail catheters than in self-locating ones (log-rank, p<0.001). Conclusion In our patients, self-locating catheters have a lower malfunction rate than other variants of Tenckhoff catheters.

The Fanconi syndrome is an array of multiple proximal renal tubular dysfunctions occurring in association with several exogenous toxins, such as aminoglycosides. These antibiotics remain the drugs of choice in most gram-negative infections, but nephrotoxicity is the main drawback for them. Furthermore, the nephrotoxic effects may be overlooked with routine analyses. With the purpose of making physicians aware of this underrecognized complication, we are reporting here 3 cases of Fanconi’s syndrome related to the administration of high-dose aminoglycosides (ranging from 3.6 to 15 g) with normal serum urea nitrogen and creatinine levels. The pattern of aminoaciduria demonstrated high increases in neutral amino acids, followed by dibasic and near-normal acidic amino acids. We also report the urinary excretion rates of total protein and β₂-microglobulin and protein electrophoresis results. We compared these cases with others reported in the literature.

Peritonitis due to Alistipes finegoldii in a patient on peritoneal dialysisDear Editor Gram-negative peritonitis is becoming one of the greatest problems in peritoneal dialysis patients. Some cases are due to abdominal catastrophe, but other cases are caused by the translocation of bacteria from the gut to peritoneum. The main bacteria in these cases are Escherichia coli, but other bacteria can cause the same issues. Here, we present a case of peritonitis due to a novel organism that resides in the gut and probably caused the peritonitis due to bacterial translocation.
