The case is reported of a young ex-nurse with severe inflammation in the distal colon, extending 15 cm proximally from the anus, due to the self-instillation of a noxious substance, namely, caustic soda. She escaped detection over a period of months. The result was extensive inflammatory change in the terminal 15 cm of the large bowel, with gross macroscopic, histological and radiological abnor...

This paper intends to provide a glimpse of the within-the-fence activity of a major chlorine, caustic soda and chlorinated hydrocarbons manufacturing complex, immediately before and during the 2 weeks following Hurricane Rita. The paper touches on the basics, covering "preparation," "perseverance" and "powering up again" as this chemical complex began to return to normal. There are expected and...

one arm. The dry proteins are dissolved in weak caustic soda and a drop placed on the abrasion. The test is complete in half an hour. An urticarial wheal with an erythematous blush around constitutes a positive reaction. Out of nearly 800 cases suffering from asthma or hay fever 200 positive reactions were obtained. Of these 28 reacted positively to some animal emanation. The largest number of ...

The ingestion of caustic soda is frequently a source complications. Esophageal stenosis remains among them the most frequent complication and by far formidable. Pyloric rare following soda. We report through this clinical case, cicatricial pyloric after associated with esophagus having caused vomiting onset severe malnutrition. diagnosis was confirmed oeso-gastro-duodenal transit (OGDT) child u...

In the Bayer process, the reaction of silica in bauxite with caustic soda causes the loss of great amount of NaOH. In this research, the bound-soda losses in Bayer process solid residue (red mud) are predicted using intelligent techniques. This method, based on the application of regression and artificial neural networks (AAN), has been used to predict red mud bound-soda losses in Iran Alumina C...
