[Trichinosis. A study of a large outbreak on the Iberian peninsula].
An epidemic outbreak of trichinosis after wild boar meat ingestion was analysed. The most frequent clinical manifestations were: muscular pain, fever, periorbitary edema and conjunctivitis. Laboratory tests showed eosinophilia and increased muscular enzymes. There was no mortality. 10 patients had electromyograms, which all showed an inflammatory myopathy pattern. The one fiber study showed similar signs as those found in cases of polymyositis. There was a significant statistical relationship between intensity and duration of symptoms in the intestinal phase and eosinophils levels in peripheral blood. There was also a statistically significant relationship between CPK levels and decrease of mean duration of motor unit potential. Treatment with thiabendazole and steroids was useful. The indirect immunofluorescence test (IIT) proved an excellent method for diagnosing trichinosis.
