bacteriologic aid in the differential diagnosis of periapical and periodontal abscesses

The aim of the present investigation was to determine whether spirochaetal count could help differentiate between periodontal and periapical abscesses. 23 draining abscesses were included, where 15 were diagnosed as periodontal and 8 as periapical, based on clinical and radiographic data. Exudate samples were collected aseptically and examined by both dark field microscopy and Gram-stained smear. The results revealed a statistically high increase in spirochaetal count in periodontal abscesses compared to periapical ones. The obvious difference appeared adequate to differentiate both lesions and establish a rapid chairside diagnostic aid

Contribuiçäo para o estudo das leptospiroses no Estado de Santa Catarina / Contribution for the study of leptospirosis in Santa Catarina State

Apresenta um relato sobre um surto de leptospirose ocorridos nos municípios de Palhoça e Säo José, Estado de Santa Catarina, no ano de 1991, em consequência de uma enchente que atingiu um grande número de moradores dessas duas cidades. Foram registrados quarenta e um (41) casos de leptospirose, todos sorovar interohaemorrhgiae RGA. A relaçäo de macroaglutinaçäo apresentou maior número de resultados positivos do que a reaçäo de micro-aglutinaçäo.
