[Eosinophilia in a family from Bosnia].

We describe reference to a family from Bosnia that the diagnosis of Trichinellosis can be difficult despite notice of travel-history and eosinophilia but lack of further epidemiological datas and due to the rarity of this zoonosis. Clinical pattern of trichinellosis are fever, headache, myalgia, periorbital oedema, less frequently diarrhea and abdominal pain. Dreaded complications are myocarditis and encephalitis. High eosinophilia and increased creatine phosphocinase activity are the most frequently observed laboratory features. The detection of specific circulating antibodies or the parasitological examination of a muscle biopsy will confirm the diagnosis. The medical treatment includes albendazol and steroid.
