Non-depolarizing neuromuscular blocking agents have been used with increasing frequency in critically ill patients. Recently, numerous reports have described patients with prolonged muscle weakness after use of these agents for more than two days. Brief weakness lasting several hours to several days is likely the result of prolonged neuromuscular blockade, while more prolonged weakness lasting several weeks to months is likely caused by a myopathy. ⋯ Selective loss of thick myofilaments on muscle biopsy has been produced experimentally in rats by combing denervation with high doses of corticosteroids. As this disorder likely leads to additional respiratory compromise, difficulty weaning from the ventilator, and prolonged hospitalization, prevention is warranted. Methods of prevention include minimizing the dosage of non-depolarizing neuromuscular blocking agents and of other drugs with an effect on the neuromuscular junction, twitch monitoring with a peripheral nerve stimulator and allowing patients to come to an unparalyzed state for brief periods.

Aluminum phosphide poisoning is common in the rural belt of Northern India. The release of cytotoxic phosphine gas primarily affects the heart, lungs, gastrointestinal tract and kidneys, although all organs can be involved. ⋯ Treatment consists of early gastric lavage, vasopressors and supportive care. Specific therapy with intravenous magnesium sulphate is recommended.

Case ReportsLiver transplantation after severe poisoning due to amatoxin-containing Lepiota--report of three cases.
Four cases of severe Lepiota poisoning, including three which developed toxic fulminant hepatitis treated by orthotopic hepatic transplantation, are reported here. The toxicity of the Lepiota is discussed as well as the indications for hepatic transplantation in poisonings due to amatoxin-containing mushrooms.

Case ReportsColchicine toxicity--clinical features and treatment. Massive overdose case report.
This is a report of colchicine poisoning in a 24-year-old woman. She developed multiple organ failure and bone marrow suppression after the suicidal ingestion of 50 (1 mg) colchicine tablets. The pancytopenia responded to granulocyte colony-stimulating factor 300 micrograms on days 4, 5, 6, and 8. Although anticolchicine monoclonal antibody administration is the only specific therapy described, intensive supportive care including granulocyte colony-stimulating factor administration can facilitate recovery from severe colchicine intoxication.

ReviewOutcome following organ removal from poisoned donors in brain death status: a report of 12 cases and review of the literature.
Experience with organ procurement from poisoned donors in brain death status is still limited in comparison with other etiologies. From 1963 to 1993, 2769 grafts (heart 141, kidney 1922, liver 623, pancreas 43) were performed in our University Hospital. Since 1975, among 1174 patients admitted to the ICU for acute poisoning, 12 patients who developed brain death status were considered for organ donation. ⋯ The one year survival rate of 75% is similar to that observed in the population who received organs from nonpoisoned donors. Organ procurement can be considered in few selected cases of acute poisoning. The accuracy of the diagnosis of irreversible brain damage is essential in this setting.
