OBJECTIVE To verify the hypothesis that the pulmonary vein pulsatility index is higher in fetuses of diabetic mothers than it is in normal fetuses of nondiabetic mothers. METHODS Twenty-four fetuses of mothers with either gestational or previous diabetes (cases), and 25 normal fetuses of mothers without systemic disease (control) were examined. Fetuses were examined through prenatal Doppler a...

More than 45,000 of 100,000 exposed patients are suffering from late effects of sulfur mustard (SM) after almost 20 years post-exposure. Respiratory complications of SM exacerbate over time and are the greatest cause of long-term disability in exposed patients. A triad of cough, expectoration and dyspnea has been found to be the main symptoms among patients. Even those who had not developed acu...

introduction pulmonary hypertension is common among patients with hyperthyroidism, and graves’ disease constitutes the most common cause of thyrotoxicosis. case presentation we report the case of a female patient admitted to the cardiology department with shortness of breath and pretibial myxedema. the diagnostic work-up revealed combined pre- and post-capillary pulmonary hypertension due to gr...

Background Aspiration of hydrocarbons causes several acute and chronic pulmonary complications; it may even lead to death. The aim of this study was to investigate the types of long-term pulmonary complications in children with a history of hydrocarbon aspiration. Materials and Methods In this case-control study, 21 children ...

background: safe exclusion and risk stratification are currently recommended for the initial management of patients with acute pulmonary embolism (ape). the aim of this study was to assess the safe exclusion and risk stratification value of d-dimer (dd) for ape when tested at the beginning of admission. materials and methods: all consecutive chinese ape patients and controls were recruited from...

OBJECTIVE Continuous positive airway pressure (CPAP) is considered an effective nonpharmacologic method of treating patients with severe acute cardiogenic pulmonary edema. However, we hypothesized that bilevel noninvasive positive-pressure ventilation (NPPV), which combines both inspiratory pressure support and positive expiratory pressure, would unload the respiratory muscles and improve cardi...

background: silicosis is known in industrial workers for centuries. till recently, the mainstay of its diagnosis and progress was clinical examination of the respiratory system, pulmonary function test and chest radiography. several biomarkers such as serum angiotensin converting enzyme (ace) activity have been examined to determine the extent of silicosis. objective: to elucidate the effect of...

We examined erythropoietin (EPO) gene expression and EPO production during hypoxia in two Sprague-Dawley rat strains with divergent polycythemic responses to hypoxia. Hilltop (H) rats develop severe polycythemia, severe hypoxemia, and pulmonary artery hypertension. The H rats often die from a syndrome indistinguishable from chronic mountain sickness (CMS) in humans. Madison (M) rats develop pol...
