[Clinico-parasitological research in a focus of intestinal nematodiasis in Habak Province (the Socialist Republic of Vietnam) and the efficacy of medamine treatment in these infestations].

The authors described the focus of intestinal nematodiasis in Vietnam with the rate of infestation on the average 74.6% for ascaridiasis, 30.8 for trichocephaliasis and 20.2% for ancylostomiasis. The high rate of the geohelminthic infestation was related with the use of untreated feces for the vegetables rearing. The clinical symptoms of intestinal nematodiasis were featured by dyspepsia, pain and asthenoneurotic syndromes. The first field trials of mediamine treatment were performed for 267 patients in the high-intense foci of intestinal nematodiasis in the tropics. In trichocephaliasis patients therapeutic efficacy of the drug was 74%, in ancylostomiasis patients it was 71.9, in ascaridiasis patients 68.4%. Retrograde ascarid migration was noted in two patients.
