Fluoropolymers are virtually inert substances that can withstand high temperatures. These two properties make them ideal for use as coatings to protect metals from corrosive attack. It is important to realize that fluoropolymer coatings are used where other polymers could not possibly survive, that is, under extremely hostile conditions. Under such conditions, permeation assumes a much more imp...

A rapid and efficient synthesis of 4,6-Dimethylpyrimidine-2(1H )-one has been carried out from acetylacetone and urea in dry media in the presence of an environmentally friendly non-corrosive, non-toxic and recyclable catalyst in 85% yield under microwave irradiation conditions.

Molten carbonate fuel cells use carbonate salts of alkali metals as electrolyte. Due to the highly corrosive nature of the electrolyte, various countermeasures are being developed. MCFCs are expected for high-efficiency power generation systems using hydrocarbon fuels, such as natural gas and coal gas. This article describes the mechanisms of operation and cell degradation, as well as the featu...

In the first 24 hours after hospitalization, an emergency esophagogastroduodenoscopy was done and corrosive damages were observed along the esophagus, in the stomach and partially in the duodenum that bled temporarily. Postcorrosive burns of the esophagus and stomach of grade III according to Kikendal’ classification were confirmed and bleeding from the mucous membrane, submucosis and muscle la...

Cyst rupture is one of the rarest complications of choledochal cysts (CC). We report an 8-year-old boy with CC rupture leading to bile peritonitis following repeated esophageal dilatations for corrosive stricture, and discuss how the esophageal dilatation procedures might constitute a predisposing factor for CC perforation.

We report a case of extensive subcutaneous extravasation of corrosive drugs used during cardiac resuscitation, in a neonate undergoing cardiac catheterization. Early management with hyaluronic acid, liposuction and saline washout of the extravasated fluid prevented development of any tissue damage. This simple technique was easy to use and extremely effective.

BACKGROUND Data on the spectrum of corrosive injury to the esophagus after paraquat or glyphosate-surfactant ingestion are sparse in the literature and confined to case studies and brief reports. Therefore, this study aimed to examine the clinical features, degrees of esophageal injury, and clinical outcomes after paraquat or glyphosate herbicide ingestion, and sought to determine what associat...
