Emergence of drug resistance in human immunodeficiency virus type 1 infected patients from pune, India, at the end of 12 months of first line antiretroviral therapy initiation.

Introduction. In India, 4,86,173 HIV infected patients are on first line antiretroviral therapy (ART) as of January 2012. HIV drug resistance (HIVDR) is drug and regimen-specific and should be balanced against the benefits of providing a given ART regimen. Material & Methods. The emergence of HIVDR mutations in a cohort of 100 consecutive HIV-1 infected individuals attending ART centre, on first line ART for 12 months, was studied. CD4(+) T-cell counts and plasma HIV-1 RNA level were determined. Result. Out of the 100 HIV-1 infected individuals, 81 showed HIVDR prevention (HIV-1 RNA level < 1000/mL), while the remaining 19 had HIV-1 viral RNA level > 1000/mL. HIVDR genotyping was carried out for individuals with evidence of virologic failure (HIV-1 RNA level > 1000/mL). The most frequent NRTI-associated mutation observed was M184V, while K103N/S was the commonest mutation at NNRTI resistance position. Conclusion. Our study has revealed the emergence of HIVDR in HIV-1 infected patients at the end of 12 months of first line ART initiation. For NRTIs, the prevalence of HIVDR mutations was 9% and 10% for NNRTIs. Our findings will contribute information in evidence-based decision making with reference to first and second line ART delivery and prevention of HIVDR emergence.

Meningitis Due to Cryptococcus gattii in an Immunocompetent Patient.

The incidence of cryptococcal infection is high in developing countries such as India. Cryptococcus gattii, formerly known as Cryptococcus neoformans var gattii, is an encapsulated yeast that causes disease in both immunocompetent and immunosupressed individuals. The organism enters via respiratory tract and causes a spectrum of illness ranging from asymptomatic infection to severe illness, including pneumonia and disseminated infection involving multiple sites, including the central nervous system, eyes and skin. Cryptococcal meningitis is generally considered as rare in immunocompetent patients; therefore, specific treatment is not implemented until the organism is identified or a cryptococcal antigen is detected. We describe the case of a 30-years-old man without prior medical history who presented with meningitis and was treated successfully. This case illustrates the importance of considering infectious causes such as C.gattii in the differential diagnosis of meningitis, regardless of the patient's immune status.

Successfully treated bizarre self-mutilation with disembowelment--case report with review of literature.

Self-inflicted abdominal stab wounds are generally uncommon and there is no published report of survivors after extensive self inflicted disembowelment with mutilation. Here we present a case of 28 year old male who was brought to hospital 2 1/2 h after disembowelment through self inflicted abdominal stab injuries. The patient had hypovolemic shock due to bleeding from the mesentery and a 450 cm segment of small bowel which had been pulled out from 2 abdominal stab wounds and slashed multiple times by him. He had alcohol intoxication and hallucinations and did not seem to be in pain or emotionally affected by the severe injury. After resuscitation, and emergency resection with anastomosis he had an uneventful post-operative recovery. On psychiatric evaluation during follow-up, he was found to have schizophrenia aggravated by alcohol abuse and was treated accordingly. As self mutilation can be the first presentation of a psychotic episode, a psychiatric evaluation is necessary for all patients with self inflicted injuries.

Enterolith with enterocolic fistula: the diagnostic approach.

An enterolith is a mixed concretion formed in GIT, usually rare in humans. Primary enteroliths are formed in small bowel, typically within a diverticulum and secondary enteroliths in gallbladder. This case report highlights the presence of an enterocolic fistula; probably a postradiotherapy complication; and an enterolith without associated small bowel or colonic diverticuli. We have discussed the various diagnostic modalities used to reach a preoperative diagnosis of this rare condition. Imaging plays an important role in the detection and management of acquired gastrointestinal fistulas. The more routine use of cross-sectional imaging (especially computed tomography and magnetic resonance imaging) has altered the standard sequence of radiologic evaluation for possible fistulas, but fluoroscopic studies remain a valuable complement, especially for confirming and defining the anomalous communications.
