Background. Inspite of the fact that accidental caustic ingestion is an entirely easily preventable problem, it has however persisted in rural Nigerian communities because the commonly implicated agent which is caustic soda (sodium hydroxide, NaOH) is sold in open markets without restrictive legislations. This study aims to identify the perpetuating factors of paediatric caustic ingestion and r...

Caustic substances cause tissue destruction through liquefaction or coagulation reactions and the intensity of destruction depends on the type, concentration, time of contact and amount of the substance ingested. We report an unusual presentation and complication of caustic ingestion in a patient, who accidentally ingested sodium hydroxide. Our patient presented respiratory failure soon after a...

Acute death from caustic ingestion is uncommon. We report an autopsy case of acute fatality from suicidal ingestion of a liquid caustic soda solution with peritoneal leakage due to a stab wound to the stomach. The victim was a 58-year-old man, who died about 1 h after being transported to a hospital emergency care unit. There were corrosive erosions around the mouth and a stab wound in the lowe...

Cotton fibres were subjected to cleaning process and then characterized for maturity. Decrystallisation and swelling processes with caustic soda, ethanol, propan-2-ol and Trichloroethene on the native fibres were carried out. The effects of these on the strength and moisture regain were investigated. The activation energies of the dyeings were also analysed with Durazol Scarlet Red 4 BAS. The r...

 Background: Sulfur compounds must be removed from petroleum because they contribute to environmental pollution. A strong alkaline solution such as caustic soda is used to remove these compounds. This spent caustic has high values for chemical oxygen demand (COD) concentration, pH and total sulfur. In this study, the regeneration and treatment methodology of sulfidic spent caustic was inve...

In a previous paper (Marchand, 1954) the sociological aspects of caustic soda poisoning in Johannesburg were discussed. That review dealt with 116 cases treated during the four-year period July, 1948, to July, 1952. A second communication (Marchand, 1955) on acute caustic injuries was based upon five years' experience and a total of 152 cases. Between July, 1953, and July, 1954, a further 56 pa...
