objectives: the aim of this study was to evaluate the etiology, associated injurers and clinical presentation of post traumatic diaphragmatic hernia. methods: this study was a cross-sectional study being conducted in the department of cardiovascular, thoracic surgery (cvts) and pediatric surgery, sher-i-kashmir institute of medical sciences (skims), srinagar, kashmir, india. all patients of pos...

Introduction: Eating fatty food is a common technique for decreasing extra cardiac activity, but sometimes patients refuse to eat fatty foods due to various reasons during myocardial perfusion imaging. The aim of this study is to introduce an alternative method for patients who are not able to use fatty foods to accelerate the transit of radiotracer from the liver. <stron...

Peptic ulcer perforation is the most common cause of pneumoperitoneum (75%). The rate of the perforation of acute appendicitis is 20-30% and the rate of its co-occurrence with pneumoperitoneum is 0-7%. In this report, a patient with sub-diaphragmatic free air due to perforated appendicitis.

Patients with respiratory muscle weakness show nocturnal hypoventilation, with oxygen desaturation particularly during rapid eye movement (REM) sleep, but evidence in individuals with isolated bilateral diaphragmatic paresis (BDP) is conflicting. The effect of sleep on relative activity of the different respiratory muscles of such patients and, consequently, the precise mechanisms causing desat...

Prolonged mechanical ventilation (MV) results in diaphragmatic atrophy due, in part, to an increase in proteolysis. These experiments tested the hypothesis that MV-induced diaphragmatic proteolysis is accompanied by increased expression of key components of the ubiquitin-proteasome pathway (UPP). To test this postulate, we investigated the effect of prolonged MV on UPP components and determined...

Mechanical ventilation (MV) is associated with diaphragmatic oxidative stress that contributes to both diaphragmatic atrophy and contractile dysfunction. However, the pathways responsible for oxidant production in the diaphragm during MV remain unknown. To address this issue, we tested the hypothesis that diaphragmatic nitric oxide synthase (NOS) activity is elevated during MV, resulting in nit...

BACKGROUND Pleural effusion adversely affects the pressuregenerating capacity of the diaphragm. It uncouples the lung and chest wall, which may result in diaphragmatic dysfunction. Information on the effects of effusion drainage on diaphragmatic function is limited, but several studies report relief of dyspnoea after drainage, which was attributed to improved diaphragmatic mechanics, even if th...

OBJECTIVE The explore the mechanism responsible for diaphragmatic contractile and relaxation dysfunction in a rat model of sepsis. METHODS Thirty-six adult male Sprague-Dawley rats were randomized equally into a sham-operated group and two model groups of sepsis induced by cecal ligation and puncture (CLP) for examination at 6 and 12 h following CLP (CLP-6 h and CLP-12 h groups). The paramete...
