in cases of congenital esophageal stenosis due to tracheobronchial remnants, symptoms of partial esophageal obstruction appear at the time of weaning or during early childhood. in the absence of esophagitis, esophagram combined with cinefluoroscopy demonstrates fixed stenosis of distal esophagus and appears to be diagnostic. dilatation of rigid stenosis is invariably unrewarding and surgical re...

Background: Skin cancer is one of the most common forms of cancer in the world and melanoma is the deadliest type of skin cancer. Both melanoma and melanocytic nevi begin in melanocytes (cells that produce melanin). However, melanocytic nevi are benign whereas melanoma is malignant. This work proposes a deep learning model for classification of these two lesions.    Methods: In this analytic s...

introduction: the incidence of malignant melanoma is increasing at a rate greater than any other human cancer. although melanoma accounts for only 4 percent of all dermatologic cancers, it is responsible for 80 percent of deaths from skin cancer; only 14 percent of patients with metastatic melanoma survive for five years. the optimal therapy varies with the stage of the disease. surgical excisi...

background: since variceal bleeding due to portal hypertension is associated with a high mortality rate, effective treatment leads to improved survival. endoscopic sclerotherapy is an effective treatment for bleeding esophageal varices, but it is associated with significant complications. to determine the efficacy and safety of endoscopic sclerotherapy, we evaluated the patients with variceal b...

despite all advances, treatment of esophageal carcinoma is still unsatisfactory. currently the standard non-surgical treatment of esophageal cancer is concurrent chemotherapy and radiotherapy (chemoradiation), with results comparable to best surgical series. a few years ago, we started a chemoradiation protocol for the cancer of esophagus as a curative treatment, of which we present the prelimi...

congenital esophageal atresia needs to be surgically corrected as soon as possible. some will present with post surgical stricture that needs to be dilated by a balloon dilator. this procedure is difficult in premature born due to infant esophageal size and availability of equipments. we herby report the first case in a premature infant with post surgical esophageal stricture of esophageal atre...
