[Trichomoniasis in the newborn (author's transl)].

Trichomonas vaginalis was diagnosed in two girls out of 948 newborn babies (0.21%) admitted for various reasons to the Universitäts-Kinderklinik Graz during a 21 months period. One of the patients revealed leukocyturia and vulvovaginitis, the other had both bacterial urinary tract infection and vulvovaginitis being controlled but incomplete with antibiotica therapy. The radiologic finding of the urinary tract were normal. In both cases trichomonas vaginalis was identified in a routine urine specimen. The infants mothers both had vulvovaginitis trichomonalis. After a 5 days course with metronidazole given orally, the symptoms ceased and the urinary tract infection healed. The influence of maternal hormones on the epithelium of the infantile vagina facilitating trichomoniasis in the newborn is discussed.
