Studies of renal involvement in thalassemia syndromes have been varied and few. The most important cause of mortality and morbidity in these patients is organ failure due to iron deposition. We report here a cross-sectional study carried out between February 2005 and February 2006 on all beta-thalassemia major patients being treated in Mofid Children's(More)
Eight young men with documented exercise-induced asthma each performed two standard exercise tests and underwent two histamine challenges on separate days after double blind administration of either 20 mg nifedipine or placebo. The response to exercise was assessed by the maximal fall in forced expiratory volume in one second (FEV1) and to inhaled histamine(More)
Dose-response relationships for salbutamol were studied in eight patients suffering from chronic airflow obstruction with no asthmatic features. Each inhaled, double blind, in randomised order 0, 200, 400, 800, and 1600 micrograms salbutamol on five successive mornings. Before and at intervals up to six hours after the inhalation FEV1, vital capacity,(More)
The effects of mitral valve disease on lung function have been studied in 26 non-smoking patients by relating values for lung volumes and carbon monoxide transfer factor (TLCO) to various indices of cardiac function measured at catheterisation. In general, more severe mitral disease was associated with greater abnormalities of lung function. Reductions of(More)
Ventilation and perfusion lung scans were performed in 58 patients before operation for bronchial carcinoma to determine in which patients the lung scan was most useful for assessing mediastinal spread and resectability of the tumour. Perfusion of the affected lung was less with larger and more centrally situated tumours. Perfusion was also less for(More)
Congenital absence of the nose or arhinia is a rare defect of embryogenesis often associated with other anomalies. Arhinia is a life-threatening condition that requires a highly skilled neonatal resuscitation team in the delivery room. The associated anomalies often have a significant effect on the immediate as well as long-term outcome of the neonate. This(More)
Lung function at rest was assessed in 50 patients before and six months after mitral valve surgery. There were small increases in spirometric volumes (FEV1 and vital capacity) with decreases in total lung capacity and residual volume, but no change in carbon monoxide transfer factor or transfer coefficient (KCO). Progressive exercise tests performed before(More)
BACKGROUND In recent years, various noninvasive respiratory support (NRS) of ventilation has been provided more in neonates. The aim of this study was to compare the effect of HFNC with NCPAP in post-extubation of preterm infants with RDS after INSURE method (intubation, surfactant, extubation). METHODS A total of 54 preterm infants with RDS (respiratory(More)
INTRODUCTION Respiratory failure secondary to pulmonary surfactant deficiency is an important cause of severe respiratory distress in term and preterm infants. The aim of this study was to evaluate the specificity and sensitivity of gastric aspirate shake test (GAST) to predict surfactant deficiency in newly born premature infants in Arash Hospital (Iran)(More)
