Acanthamoeba meningoencephalitis in immunocompetent: A case report and review of literature.

A 30-year-old manual laborer from Karnataka, India presented with intermittent low grade fever and diffuse headache for 1 month. On examination, patient had enlarged supraclavicular and cervical lymph nodes. Patient had positive Kernig's sign and neck stiffness. Motor, sensory and cranial nerve examinations were within the normal limits. Abdominal, cardiovascular and chest examination did not yield any positive findings. Contrast enhanced computed tomography head was normal. Patient was suspected to have extrapulmonary tuberculosis. Patient was started on antitubercular drugs. Diagnostic lumbar puncture was performed. Wet mount and Giemsa smear preparation of cerebrospinal fluid (CSF) showed trophozoites suggestive of Acanthamoeba. CSF was cultured onto non-nutrient agar with an overlay of Escherichia coli. Wet mount made from the culture media yielded cysts and trophozoites of Acanthamoeba spp. Patient was diagnosed with Acanthamoeba meningitis and was started on specific therapy with Rifampicin 600 mg once a day, Cotrimoxazole 960 mg twice-a-day and Fluconazole 400 mg once daily for 2 weeks. Patient had a complete recovery and was discharged from the hospital.

Evaluation of central venous catheter associated blood stream infections: a microbiological observational study.

There are substantial morbidity and mortality associated with vascular catheter use among crictically ill patients. The attributable mortality is 10% to 25% which is associated with bacteremia among those who are hospitalized. This study was undertaken to identify catheter related blood stream infections, to isolate pathogenic microorganisms present in intravascular catheter related local infections, exit site infections, and to determine the predisposing factors for the development of such infections and antibiotic sensitivity pattern of the isolated organisms in tertiary care hospital.

Primary tubercular psoas abscess: a rare presentation.

Primary tubercular psoas abscess is a rare clinical entity and has seldom been reported in an otherwise healthy person. Here we report an interesting case of primary tubercular psoas abscess in an immunocompetent male with no other traceable source.

Primary hydatid cyst of the kidney and ureter with hydatiduria in a laboratory worker: a case report.

Hydatid disease is frequent in endemic regions and sheep farming areas. Most common localization of hydatid cyst occurs in liver followed by lungs. Renal hydatid cyst constitutes about 2-4% of all locations. We report a case of left renal hydatid from a laboratory technician admitted in a tertiary care hospital. There were few cases of renal hydatid disease reported in India among general population but to the best of our knowledge never reported from laboratory worker. The possibility of laboratory-acquired infection cannot be ruled out in this case due to lack of precautionary measures and containment facilities in resource-constrained setting.

Primary Amoebic Meningoencephalitis in an Infant due to Naegleria fowleri.

Primary amoebic meningoencephalitis (PAM) caused by free-living amebae Naegleria fowleri is a rare and fatal condition. A fatal case of primary amoebic meningoencephalitis was diagnosed in a 5-month-old infant who presented with the history of decrease breast feeding, fever, vomiting, and abnormal body movements. Trophozoites of Naegleria fowleri were detected in the direct microscopic examination of CSF and infant was put on amphotericin B and ceftazidime. Patient condition deteriorated, and he was discharged against medical advice and subsequently expired. We also reviewed previously reported 8 Indian cases of primary amoebic meningoencephalitis (PAM) and observed that for the last 5 years, none of the patients responded to amphotericin B. Has an era of amphotericin B-resistant Naegleria fowleri been emerged? Management strategy of PAM needs to be reviewed further.
