[Ovarian cysts in adolescent girls: report of 196 cases]. / Torbiele jajników u dziewczat--obserwacje wlasne 196 przypadków.

OBJECTIVES: The aim of the study was a retrospective analysis of the procedure employed at girls with diagnosed ovarian cyst changes. MATERIALS & METHODS: The material examined was 196 girls (at the age 9-20) with diagnosed ovarian cyst changes being medical treatment in Research Institute Polish Mother's Memorial hospital between 1995-1997. Operations were performed because of the pains or ultrasound suspected features. The patients who were not operated on were under observation and had ultrasound tests every two months. The presence of the change was the indication for sonographically guided fine needle puncture. RESULTS: From among 196 patients 15 (7.6%) were initially qualified for the operation because of strong pains or ultrasound equivocal changes. After two months observation (with gestagen or estrogestagen formulations being used) no cysts were found at 141 (72%) patients. After another two months no cysts were found at another group of 10 (5.1%) patients. 30 (15.3%) patients had find needle puncture. No malignant tumours were in the observed group found. CONCLUSION: Clinical observation periodically repeated ultrasound tests seems to be the most appropriate procedure employed at adolescent girls with asymptomatic ovarian cysts.

Infection of Syrian hamsters with Lyme disease spirochetes.

Syrian hamsters were shown to be susceptible to infection by the Lyme disease spirochete Borrelia burgdorferi. Although these spirochetes did not cause any outward signs of illness in these animals, they did cause a generalized infection. Spirochetemia was present during the first 6 days of infection. At 14 days postinfection, spirochetes could be isolated from one or more of the following organs: spleen, eyes, kidneys, liver, testes, and brain. Spirochetes were isolated from the eyes and kidneys of one animal 52 days postinfection, suggesting that these organisms may cause a persistent infection. Virulence of B. burgdorferi is maintained by animal passage but is lost upon prolonged in vitro cultivation.
