We describe four patients who developed an encephalopathic syndrome characterized by obtundation or stupor, myoclonic jerks, and asterixis in association with cefuroxime therapy. Three patients had renal failure. These cases suggest that cefuroxime in overdose or in conventional doses in patients with renal failure can cause a reversible encephalopathy. This syndrome may have been unrecognized because it usually occurs in severely ill patients with additional causes for encephalopathy.
Wernicke’s encephalopathy (WE) is most commonly associated with alcoholism, although other causes have also been implicated. In the years 1994–1997, 9 patients with no history of alcohol abuse presented with acute signs of ophthalmoplegia or nystagmus and ataxia which resolved within 48 h after intravenous thiamine. There were 7 women and 2 men aged 17–57 (7 below the age of 30). Precipitating events included vomiting 2, drastic weight-reducing diet 2, renal colic in a postpartum woman 1, colonic surgery 2 and chronic hemodialysis 1. In 2 patients there was no obvious precipitating event but their history was suggestive of a genetic predisposition. Mental changes were slight or absent in all patients and all of them made good functional recovery. These cases suggest that the diagnosis of WE should be considered more often in nonalcoholics in various clinical settings.
Five cases of motor neuron disease occurred during the period 1983-1987 in 4 small and medium-sized textile factories. These cases were 45% of 11 motor neuron disease patients diagnosed in this period in a population of about 300,000 persons. This observations may be relevant to toxic occupational hazards in the pathogenesis of motor neuron disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
