Phenotypic and genotypic detection of carbapenemase production among gram negative bacteria isolated from hospital acquired infections.

Objectives: To identify the carbapenemase producing Gram-negative bacteria (GNB) by phenotypic methods and to confirm the presence of resistant genes using real-time polymerase chain reaction (PCR).

Methods: This was a prospective study carried out at the Department of Microbiology, Sri Venkata Sai Medical College and Hospital, Mahabubnagar, India, from March 2018-2021. All samples were screened for carbapenem resistance by disc diffusion method and the VITEK2 compact system (bioMérieux, France).

Management for carotid body paragangliomas.

The carotid body tumor is a rare neoplasm that has generated much literature over the last century, and for which continued controversy exists regarding natural history, biologic behavior, proper technique of excision, and the risk of morbidity and mortality. The present study reviewed a 16-year experience of managing carotid body paraganglioma (CBP) between 1988 and 2004. There were 10 consecutive patients aged between 18-42 years with tumors and median follow-up was 10 years.
