Congenital Hydronephrosis in a New-born Infant

The patient, a girl of seventeen years, was admitted to the MIater Infirmnorum Hospital on 3rd November, 1933, as a case of acute appendicitis. She gave a typical history of abdominial pain follovwed by nausea and vomiting, the pain later settling down in the right iliac fossa, where, on admissioni, she was tender and rigid. Immecliate operation was decided onl. At operationi niothing unusual was noticed, the appendix showing sigIns of acute iniflammationi in its early stages. An uneventful, rapid, convalescenice followeed. On openiing the appendix after the operation I was surprised to finld wlhat at first I thlought was an oratnge pip in the terminal endc of the organi with a ftecolith proxinmal to it, blockinig the lumeni. Active movements of the "pip,'" howesever, proved it to be very much alive, and microscopic examination showed it to be a segment of a tapeworm. 'I[le girl gave no history of having passed any segnmenits of tapeworm, though of course she may niot have been willing to admit it, and onie consequently cannot place any reliance onl this. It wNas not thought advisable to treat her for tapeworiml utitil fulls recovered from her operationi, and presstire of cases (lid not allow her to be kept for further treatment.
