INTRODUCTION Acute corrosive poisonings are caused by ingestion of corrosive chemicals which are most commonly used as household agents. Intoxications with these kind of agents produce numerous and severe post-corrosive complications of the upper gastrointestinal tract. On the other hand, our experience showed that corrosive agents may also cause injuries of the respiratory system, which makes ...

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...

Underwater superoleophobic materials with low adhesion have been widely researched owing to their self-cleaning and anti-corrosive properties. In this study, polypyrrole (PPy) nanowire meshes have been successfully fabricated by in situ electrochemical polymerization on stainless steel mesh substrates in the presence of phosphate buffered saline as both an electrolyte and a dopant. PPy nanowire...

Ingestion of corrosive substances may cause severe to serious injuries of the upper gastrointestinal tract and the poisoning can even result in death. Acute corrosive intoxications pose a major problem in clinical toxicology since the most commonly affected population are the young with psychic disorders, suicidal intent and alcohol addiction. The golden standard for determination of the grade ...

Method Computerized clinical records of forty four diagnosed corrosive esophageal stricture patients from March 2007 to Dec 2014 were retrospectively analyzed. Patient of all ages, both sexes, medically fit and corrosive stricture involving thoracic esophagus only were included in the study. Medically unfit patients and corrosive stricture involving the larynx, cervical esophagus and stomach we...

Introduction: Corrosive ingestion is the major cause of esophageal stricture in our country. Mitomycin–C, an anthracycline derived from Streptomyces caespitosus, has both antineoplastic and antiproliferative properties. Use of mitomycin–C have been well documented in various ophthalmologic procedures and laryngo-tracheal conditions where it has been shown that mitomycin–C inhibited fibroblast p...

Although dilatation is the treatment of choice for most patients with benign oesophageal strictures, there is little information on its efficacy and safety in corrosive oesophageal strictures. Of 123 adults with benign oesophageal strictures treated by endoscopic dilatation, 52 (42.3%) had strictures after corrosive ingestion and 39 (31.7%) had peptic strictures. Treatment was considered adequa...

Sodium hydroxide (NaOH) is well known for its corrosive properties and its ability to generate heat on contact with water. The respiratory effects of industrial exposure to NaOH have, however, never been reported. A 63 year old man worked daily for 20 years cleaning large industrial jam containers by boiling lye (NaOH) solution without using respiratory protective equipment. Physical examinatio...
