pulmonary tuberculosis is a common infection worldwide. in the eastern part of iran, fluctuations in tuberculosis prevalence are seen due to the migration of people from afghanistan. the aim of this study was to evaluate the time of bacteriologic sputum conversion after treatment and affecting factors in those whose smear does not become negative. this study was carried out on 85 smear-positive...

The mysterious death of Mr. Alexander Litvinenko who was most possibly poisoned by Polonium-210 ((210)Po) in November 2006 in London attracted the attention of the public to the kinetics, dosimetry and the risk of this high radiotoxic isotope in the human body. In the present paper, the urinary excretion of seven persons who were possibly exposed to traces of (210)Po was monitored. The values m...

The purpose of this experiment was to measure, by using 13C labeling, the oxidation rate of exogenous lactate (25 g, as Na+, K+, Ca2+, and Mg2+ salts) and glucose (75 g) ingested simultaneously (in 1,000 ml of water) during prolonged exercise (120 min, 65 +/- 3% maximum oxygen uptake in 6 male subjects). The percentage of exogenous glucose and lactate oxidized were similar (48 +/-3 vs. 45 +/- 5...

BACKGROUND Food allergy is the most common cause of anaphylaxis outside the hospital setting. OBJECTIVE We sought to determine the rate, circumstances, and risk factors for repeated doses of epinephrine in the treatment of food-induced anaphylaxis in children. METHODS Anonymous questionnaires were distributed to families of children with food allergies during allergy outpatient visits to a ...

PURPOSE The present study examines the relationship between the dose of acetaminophen reported to have been ingested by patients and the occurrence of serum acetaminophen levels above the 'possible toxicity' line in patients presenting at the hospital after acetaminophen overdose. The prognostic value of patient-reported dosage cut-offs of 8, 10 and 12 g was determined. METHODS This retrospec...

Background: Although foreign body ingestion is a common problem, poor knowledge for the treatment still remains a major obstacle, especially in preventing complications. Phosphate enemas were applied for chronic constipation and bowel cleansing for a long period of time. This study aims to evaluate the effect of phosphate enema on bowel movements in patients who suffer from foreign body ingesti...
