Isolated cold abscess of the thigh in an immunocompetent infant.

Isolated cold abscess of the thigh without active tuberculosis elsewhere in the body is a rare entity, and only a few cases have been reported in the literature. We report a case of isolated cold abscess of the thigh following DPT vaccination in an immunocompetent child. The association with DPT vaccination is intriguing and requires further research.

Pulmonary hydatidosis: an unusual cause of haemoptysis.

A 28-year-old female patient was referred to us with complaints of massive haemoptysis and cough with expectoration, of two years' duration. Her chest radiograph, computed tomography scan and video-bronchoscopy revealed a cystic lesion in the right upper and lower zones of the lungs.

Beta-lactamase producing Pseudomonas aeruginosa in hospitalised patients.

Beta lactamase continues to be the leading cause of resistance to beta lactam antibiotics in gram-negative bacteria. A total of 50 clinical isolates of Pseudomonas aeruginosa were studied to determine the prevalence of ESBL production in hospital strains and also to study their susceptibility to various other antimicrobial agents. ESBL production was observed in a total of 18/50 (36%) of cases.
