The Rare Imitator : Pulmonary Nocardiosis Mimics Tuberculosis Reactivation

Pulmonary Nocardiosis is a rare bacterial infection of lungs, caused by a filamentous bacterium. Immunocompromised people are known to be at danger, but there are other new emerging risk factors to consider. The presentation and clinical course in such patients differ from the previous. Here the present case is aimed to underline the presentation and diagnosis in non-risk individual.

Acute lower respiratory tract infections in children.

Acute lower respiratory tract infection (ALRTI) is a common illness, but there have been relatively few studies of the bacterial etiology in developing countries. Nasopharyngeal aspirates of 70 children under 10 years of age with ALRTI were cultured for aerobic bacterial pathogens. Klebsiella pneumoniae was the commonest organism (32.2%) isolated followed by S. pneumoniae (10%), E. coli (10%), P. aeruginosa (5.7%), S. aureus (2.8%) and H. influenzae (1.4%). There were significantly more bacterial pathogens isolated in children <1 year of age (73.7%) than in those >1 year of age (56.2%) (P=0.03). A shift in spectrum from Gram-positive cocci to Gram-negative bacilli in ALRTI was observed in our study.

Pseudomonas aeruginosa meningitis in post neurosurgical patients

Background and Objective: Pseudomonas meningitis is a rare complication following neurosurgical procedures and is associated with high mortality and mortality. The aim of the study was to describe the clinical characteristics and risk factors associated with mortality in patients who developed nosocomial Pseudomonas meningitis following neurosurgical procedure. Methods: All patients with nosocomial post-surgical meningitis due to Pseudomonas aeruginosa diagnosed in the year were reviewed retrospectively. Results: During the period of the study, 121 cases of post surgical meningitis were diagnosed. Ten (9.9%) nosocomial Pseudomonas meningitis were identifi ed. Eight patients had external ventricular drain. The antibiotic susceptibility of 10 strains was: imipenem (9/10), meropenem (7/10), amikacin (7/10), piperacillin / tazobactum (5/10), ceftrizxone (4/10), cefepime (3/10). The overall mortality was high at 80%, despite most receiving appropriate antibiotics. Conclusion: Postoperative Pseudomonas meningitis is associated with high mortality.

Cryptococcal granulomas in an immunocompromised HIV-negative patient.

Disseminated cryptococcosis usually occurs in immunocompromised individuals with defective cell-mediated immunity, most commonly seen with HIV infection. We present a case of disseminated cryptococcosis in an HIV-negative male patient who presented with headache, fever, altered sensorium of short duration and multiple cutaneous lesions. An emergency CT scan of the head showed multiple intracranial and intraventricular granulomas. Routine laboratory investigations were within the normal range. A CSF examination revealed capsulated yeasts on India ink and a culture yielded cryptococcus neoformans. A cryptococcal antigen test by latex agglutination kit was positive. A biopsy revealed multiple capsulated yeasts cells in the cutaneous lesions, which were consistent with cryptococcus neoformans. The patient was successfully treated with Amphotericin B and Fluconazole with regression of cranial and cutaneous lesions.
