OBJECTIVE To evaluate the endoscopic dilatation of benign esophageal strictures and its outcome. METHODS A prospective descriptive study was conducted at Surgical Unit 4 of Civil Hospital Karachi, over a period of 24 months, from August 2006 to July 2008. Twenty seven patients with benign esophageal strictures underwent esophageal dilatation under fluoroscopic guidance using Savary Gilliard D...

Corrosive sulfur and the effect that it has in transformer systems can be significant. The extent of the corrosion damage caused by sulfur, if left unchecked, can be so severe as to cause failure of the apparatus. The problems with corrosive sulfur have been recognized for quite some time. As early as 1948, F.M. Clark and E.L. Raab [1] issued a report on the subject for method development withi...

BACKGROUND Corrosive esophageal burns, particularly common in developing countries, lead to different problems in different age groups. The ingestion of corrosive substances can cause such problems as stricture of the esophagus, to acute perforation, and even death. Because stricture formation is related to the severity of the initial injury, the prevention of stricture constitutes a main goal ...

Atmospheric corrosion occurs under alternate cycles in presence and absence of an electrolyte layer, the severity of corrosion processes that occur onto the metallic surface depends largely on the corrosive environment to which the material is exposed. Whereas the corrosive phenomena occur in the presence of the electrolyte, in this work the effect of the depth of the solution layer on the elec...

There is an ever-greater emphasis on the maintenance of professional standards in communication among medical professionals. Much of the focus to date revolves around discourse between patients and families in the clinical arena and reflects standards developed by accrediting agencies and the government. Little has been written about the communication among professionals occurring in the admini...

Time of wetness, 2 SO and − Cl pollutants are three key factors for the selection of metal materials in engineering applications and the determination of atmospheric corrosivity categories. In the past, when one or more corrosive factors data is missing, corrosive factors categories were often subjectively determined according to expert experience. In order to overcome such difficulty, this pap...

Corrosive esophagitis is characterized by caustic injury due to the ingestion of chemical agents, mainly alkaline substances such as detergents. Esophageal bleeding, perforation, or stricture can be worsened by high-degree corrosive esophagitis. Picosulfate is a commonly used laxative frequently administered for bowel preparation before colonoscopy or colon surgery. Picosulfate powder should be...
