To investigate the cause and the mechanisms responsible of the compulsive thirst and excessive fluid intake observed in many patients on chronic dialysis treatment, we measured plasma antidiuretic hormone (ADH), angiotensin II (Ang II) and some hemodynamic parameters in seven polydipsic and in six normodipsic patients before hemodialysis, at the end of it(More)
To assess the cardiological status of patients with long-term lupus nephritis we evaluated 30 patients (mean age 43 +/- 11 years) with lupus nephritis lasting from at least 10 years (mean 15 +/- 5 years). At the time of cardiological evaluation the mean plasma creatinine was 132.6 +/- 11.1 mumol/l and in 28 patients lupus had been quiescent for at least 3(More)
The aim of the study was to assess the efficacy of the preoperative sodium Naproxen administration to reduce analgesic requirements in the postoperative period. 75 patients (ASA I-II), 50 male and 25 female, aged between 25 and 70 years and weighed between 50 and 90 kg, undergoing lumbar laminectomy were subjected to the same anesthetic technique.

In this retrospective non-randomized study we reviewed the outcome for 41 patients with membranous nephropathy older than 65 years at onset and followed for at least 1 year. Twelve of the patients never received any specific treatment (group A), 15 were treated with a 6-month course of methylprednisolone alternated to chlorambucil every other month (group(More)
The authors discuss the numerical increase in fractures of the acetabulum and the extent of surgical indications for their treatment, emphasizing the modernness and the usefulness of methods used to save blood in this type of surgery, which often involves a considerable loss. Out of 150 operations performed between 1985 and 1990 for trauma of the pelvis,(More)
Changes in mixed venous oxygen saturation of hemoglobin (SvO2), heart rate (HR), cardiac index, (SI) were measured in 20 patients undergoing major orthopedic surgery (rachis and pelvis bone resections for tumours: mean-lasting 8 hours), to estimate the safety limits during isovolemic hemodilution. Up to Hb 8 g%, in all patients, a cardiac index improvement(More)
The authors compare the results obtained in a group of 100 patients submitted to pertrochanteric osteosynthesis during the year 1991 (50 with a gamma nail and 50 with a compression-sliding plate) based on parameters of anesthesiology. The same type of anesthesiology was used in all 100 of the patients, as similar were the general clinical conditions of the(More)
