Juvenile nasopharyngeal angiofibroma (JNA) is a rare, benign and locally invasive tumor. Massive bleeding because of vascularity of tumor and postoperative recurrence are potential problems of management. Endonasal approach reduces the rate of postoperative recurrence, intraoperative bleeding, and complications of surgery, time of operation and duration of hospitalization. In this article, we r...

we present a case of caustic ingestion by a 1.5-year-old boy. the caustic agent was drain opener which is a strong alkaline substance. children in iran and many other countries are still exposed to not “child proof” (child resistant packaging) toxic substance containers. ingestion of caustic agents may lead to necrosis, perforation, and strictures. substances that are ingested more frequently a...

endoscopic retrograde cholangiopancreatography (ercp) is a specific technique used to study the pancreatobiliary system that is performed in hepatogastroenterology centers. recent, common uses for therapeutic ercp are largely due to advanced imaging techniques such as magnetic resonance cholangiopancreatography and endosonography. in the united states alone, over 500,000 therapeutic ercp are pe...

aim : the aim of this study was to analyze clinical findings and treatment outcomes of patients with endoscopic retrograde cholangiopancreatography complications. background : endoscopic retrograde cholangiopancreatography has become a very common procedure for the evaluation and treatment of biliary and pancreatic diseases. patients and methods : a retrospective review of 2447 endoscopic retro...

The effectiveness of radiofrequency (RF) cordotomy of segmental motoneurone pools of the lumbosacral cord in reducing spasticity of decerebrate cats is evaluated. The need for a new form of therapy for clinical spasticity is based upon the limitations of contemporary methods, including surgical and pharmacological techniques. In man, spasticity of spinal origin may be treated effectively by int...

Carcinoma of Bronchus-Garnett et al. MEDICALIJSUHNAL the explanation for the absent lobar perfusion in the other four patients in group 1. However, it is also possible that the bronchial tumour was producing obstructive emphysema, in which case it is postulated that the intra-alveolar pressure may then have been sufficient to prevent the radioactively labelled microemboli from entering the emph...

STUDY DESIGN Examination of hyaluronidase-4 (Hyal-4) expression in a rat spinal cord hemisection model. PURPOSE To determine the status of Hyal-4 expression after hemisection of the spinal cord, and the relationship between its expression and that of chondroitin sulfate proteoglycans (CSPGs). OVERVIEW OF LITERATURE CSPGs are expressed at the site of spinal cord injury and inhibit axon regen...
