title: Intestinal giardiasis, steatorrhoea and peripheral nerve dysfunction.
abstract: Two patients presented with similar peripheral neuropathic symptoms. Muscle denervation was shown by electromyography and muscle biopsy. Motor and sensory nerve conduction studies were normal. Both patients had intestinal giardiasis: 1 had asymptomatic steatorrhoea, and the other had diarrhoea and abdominal pain. Treatment with metronidazole abolished the gastrointestinal symptoms. After a delay of several months the neurological symptoms also gradually improved. No other cause of peripheral neuropathy was apparent on investigation, and the relationship between the intestinal giardiasis and the peripheral neuropathy is discussed.
