3523. New concepts in the pathogenesis and modalities of the chemoprophylaxis of native valve endocarditis.
Recommendations for the prophylaxis of BE have changed over the last 10-15 years toward fewer-dose and oral regimens. An advisory committee of the AHA is currently formulating new guidelines for the prevention of BE that will likely be promulgated in 1990 or 1991. It is anticipated that such recommendations will feature the new information on MVP and focus on oral prophylactic regimens.
3525. Bronchoscopic localization and treatment of occult lung cancer.
The flexible fiberoptic bronchoscope is currently the standard tool for localization of radiographically occult carcinomas of the tracheobronchial tree. It allows direct inspection of proximal airways and can establish the location of most occult lung cancers. A small percentage of patients present with bronchoscopically as well as radiographically occult carcinoma, particularly challenging because definitive localizations is required before a therapeutic plan can be outlined. Selective cytologic brushing of each lobar segment, taking random biopsy specimens, has been used to assist in localization of these early cancers. Recently, fluorescent compounds have been used to assist in localizing early lung cancers and in the treatment of radiographically occult carcinoma. We review the current methods of bronchoscopic localization and treatment of radiographically occult lung cancer.
