BACKGROUND Conservative treatment of inoperable bowel obstruction in terminal cancer patients has been found to be effective in controlling the distressing symptoms caused by this complication. The purpose of this study was to evaluate the efficacy of octreotide in the management of nausea, vomiting and abdominal pain, secondary to bowel obstruction in(More)
The main aim of this study was to evaluate the response of total Sialic Acid (TSA) and "Lipid-bound" Sialic Acid (LSA) compared to Carcinoembryonic Antigen (CEA), in 284 patients undergoing radiotherapy. Serial measurements of TSA by the enzymatic method (Boehringer-Mannheim Kit), LSA by the resorcinol-HC1 (Katopodis and Stock) and CEA by EIA (Abbott Kit)(More)
In this study the ammonia concentration was determined in arterial and venous blood samples pre- and posthemodialysis (HD) in 18 uremic patients and in 18 health subjects (controls). The mean values (+/- SD) of ammonia in the arterial blood of uremic patients pre-HD were 98.32 +/- 26.55; post-HD, 63.18 +/- 17.09; and in control group patients, 72.37 +/-(More)
This study deals with the effect of radiation treatment (RT) on serum transferrin and tumor necrosis factor-alpha (TNF-alpha) in patients with malignant tumors. In 21 patients who received 36-60 Gy in 20 to 30 sessions of RT, serum transferrin and TNF-alpha were determined pre-RT, after 10 to 15 sessions (middle of RT) and after 20 to 30 sessions (end of(More)

A 16-year-old male presented with a sudden, severe right scrotal pain at rest, occurred within the last 2 hours. The patient had a history of right orchidopexy 12 months ago. There was no associated fever, injury, or sports activity.(More)
Total sialic acid (TSA) and "lipid-bound" sialic acid (LSA) were evaluated in comparison to carcinoembryonic antigen (CEA) and ferritin and neuron specific enolase (NSE) in 152 untreated patients with primary lung cancer, 107 benign pulmonary disease patients and 207 notmal controls. The mean concentrations of TSA, LSA and CEA in lung cancer patients, were(More)
BACKGROUND In aortic reconstruction, intestinal and muscular ischaemia in the lower limbs occurs during cross-clamping of the aorta. After restoration of blood flow, reactive oxygen intermediates may lead to systemic injury to local or remote organs. In this study we investigated the usefulness of a shunt and vitamin E administration against the oxidant(More)
Removing a foley catheter can sometimes be a challenge, especially when it is related to non-deflating balloons which represent most of the cases. In female patients, due to their urethral anatomy, several techniques have been proposed for balloon puncture when other maneuvers have failed. We present a simple technique for non-deflating balloon catheter(More)
