introduction: chronic mountain sickness (cms) represents a syndrome of secondary polycythemia along with thrombocytopenia, altered hemorheology, pulmonary and systemic hypertension, and congestive heart failure, occurring due to hypobaric hypoxia-anoxia-induced erythropoiesis reported in both native mountain residents and new climbers after prolonged stays at high and extreme altitudes.case pre...

central anticholinergic syndrome (cas) following general anesthesia (ga) is a well known syndrome in children and adults. many cases of cas have been previously reported in the literature. however, there are only two reports of post resuscitation cas after administration of small doses of atropine. hereby, we report a case of cas in a child undergoing complete dental restoration under ga after ...

allgrove syndrome also known as triple-a syndrome is an autosomal recessive disorder characterized by alacremia, achalasia and acth-resistant adrenal insufficiency. although this syndrome is rare, herein we report four cases with different clinical manifestations. they were referred to the gastrointestinal ward during a one year period with complaints of vomiting and dysphagia. the diagnosis of...

total or partial absence or excess of the sex chromosomes produces different karyotypes and phenotypical abnormalities. upon retrospective analysis of the results of 163444 cytogenetic tests that were performed during 28 years (1987-2015) in this center, different types of sex chromosomal aberrations and the clinical phenotypes are delineated in this article. moreover, the clinical course and t...

triple a syndrome (allgrove syndrome) is a rare inherited autosomal recessive disease with a typical triad including adrenocorticotrophic-hormone-resistant glucocorticoid insufficiency, reduced or absent tearing (alacrima) and achalasia and a wide range of symptoms can be detected due to multi organ involvement. this report describes the case of a triple asyndrome, a12 year-old boy with a histo...

BackgroundA sufficient supply of oxygen is crucial to avoid hypoxic cardiac arrest and brain damage within 30 min in completely-buried avalanche victims. Snow density influences levels hypoxia hypercapnia. The goal this study was investigate the effects hypercapnia on cerebral oxygenation (ScO2) humans breathing into an artificial air pocket.MethodsEach subject breathed a closed system (air-tig...

A known case of nephrotic syndrome aged 32 months was admitted to ICU because of loss of consciousness. In physical exam he had tachycardia, tachypnea and hypotension. Lab data showed metabolic alkalosis and hypoxia. In CXR, vascular cut off was seen in right lung and perfusion lung scan showed absence of perfusion in the right lung.Treatment was started with heparin and streptokinase, bu...
