Urinothorax is a rather rare cause of pleural effusion and its potential mechanism is urinary tract obstruction or trauma that results in urine leakage and accumulation inside the pleural space. Patients with non-Hodgkin lymphoma could present with pleural effusion due to mediastinal lymphadenopathy or extrathoracic manifestation such as urinary tract(More)
OBJECTIVE It has been suggested that reactive oxygen species play a pivotal role in the initial organ-tissue injury during reperfusion, eliciting inflammatory reaction and multiple organ failure. It was investigated if hypoxemic reperfusion attenuates tissue injury and inflammatory response. DESIGN Randomized animal study. SETTING Medical school(More)
BACKGROUND Liposomal cisplatin is a new formulation developed to reduce the systemic toxicity of cisplatin while simultaneously improving the targeting of the drug to the primary tumor and to metastases by increasing circulation time in the body fluids and tissues. The primary objectives were to determine nephrotoxicity, gastrointestinal side-effects,(More)
The purpose of this study was to investigate the effect of chronic renal failure (CRF) and continuous ambulatory peritoneal dialysis (CAPD) on respiratory muscle function. Global respiratory muscle strength was assessed by measuring mouth pressures during maximum static inspiration (PIMAX) near residual volume (RV) and expiration (PEMAX) near total lung(More)
Chronic obstructive pulmonary disease, namely, pulmonary emphysema and chronic bronchitis, is a chronic inflammatory response of the airways to noxious particles or gases, with resulting pathological and pathophysiological changes in the lung. The main pathophysiological aspects of the disease are airflow obstruction and hyperinflation. The mechanical(More)
Aberrant Right Subclavian Artery (ARSA) is a rare vascular anomaly. It is though the most frequent anomaly involving the aortic arch, being present in about 1% of the general population. We present a case of a 71 year old male with symptoms of chronic cough and dysphagia. He was referred to our clinic for further evaluation of a mediastinal mass. A second(More)
The "reversed halo" sign (RHS) is a distinct radiological sign representing a focal rounded area of ground-glass opacity surrounded by a more or less complete ring of consolidation. Initially, it was reported in two cases of cryptogenic organizing pneumonia and was considered to be relatively specific of the disease. Since then, it has been reported in a(More)
PURPOSE Hemorrhagic shock and resuscitation is frequently associated with liver ischemia-reperfusion injury. The aim of the study was to investigate whether hypoxemic resuscitation attenuates liver injury. METHODS Anesthetized, mechanically ventilated New Zealand white rabbits were exsanguinated to a mean arterial pressure of 30 mmHg for 60 minutes.(More)
Tuberculosis (TB) caused by the human pathogen Mycobacterium tuberculosis, is the leading cause of morbidity and mortality caused by infectious agents worldwide. Recently, there has been an ongoing concern about the clarification of the role of specific human genes and their polymorphisms involved in TB infection. In the vast majority of individuals, innate(More)
The intercellular cell-adhesion molecule-1 (ICAM-1) is a transmembrane molecule and a distinguished member of the Immunoglobulin superfamily of proteins that participates in many important processes, including leukocyte endothelial transmigration, cell signaling, cell-cell interaction, cell polarity and tissue stability. ICAM-1and its soluble part are(More)
