Encephalcoele- A Cause of Recurrent Meningitis.

There are many causes of recurrent meningitis of which anatomical defects such as cephalocele are common. We report a case of a 45 year-old woman who presented with recurrent meningitis and was found to have an underlying naso-ethmoid encephalocele .

Fever of Unknown Origin (FUO) in HIV Infection in the Era of Antiretroviral Treatment (ART) in India: Development of a Simple Diagnostic Algorithm.

Objective: Fever of unknown origin (FUO) is a challenging problem among people living with HIV (PLHIV). With increasing access to Anti-retroviral treatment (ART), the spectrum of causes of FUO has evolved in the developed world. This study evaluated the etiology of FUO among PLHIV in the era of ART in India. Methodology: This prospective study was conducted at a tertiary-care institution in New Delhi, India. Sixty four PLHIV with a diagnosis of FUO were assessed by detailed clinical evaluation and immunological assessment. Specific investigations to identify the etiology of fever: microbiological and radiological investigations, bone marrow and histopathological examination of biopsies were performed. A simple diagnostic algorithm for FUO was developed based on the findings. Results: Sixty five episodes of FUO were studied. Seventy percent of subjects were men, 76% were <40 years of age, and 39% were receiving ART. The mean CD4 count was 156.57±178.43 cells/mm3 (5 to 1144 cells /mm3) and 23% patients had CD4 counts <50 cells/mm3. The mean duration of fever was 11.26±8.54 weeks. Infections were the most common cause for FUO, with Tuberculosis the most common (61.54%), particularly disseminated tuberculosis (41.54%). Cryptococcal meningitis (7.69%), bacterial pneumonia (4.62%), pyogenic abscesses (4.62%), Pneumocystis jirovecii pneumonia (PCP) (3.08%), visceral leishmaniasis (3.08%) were other infections observed. Non-infectious etiologies including lymphoma (4.62%) and progressive multifocal leucoencephalopathy (PMLE) (3.08%) were also seen. The etiology remained undiagnosed in 6.15% episodes. Importantly, two or more concurrent etiologies of fever were seen in 60% of patients. Conclusion: Infections especially Tuberculosis remain the most common cause of FUO in PLHIV even in the era of ART in developing countries like India. Multiple concurrent infections and a rising trend to non-infectious causes are being observed. A simple diagnostic algorithm will help diagnose majority of FUO even at the peripheral centers.

A two-site hospital-based study on factors associated with nonadherence to highly active antiretroviral therapy.

Objectives : To describe the pattern of adherence to Highly Active Antiretroviral therapy (HAART) and ascertain the factor(s) associated with nonadherence. Methods: This was a cross-sectional, two-site, hospital-based study. The study was undertaken in 2005; as a result of phased roll out of free HAART as part of National AIDS Control Program, patients at Lok Nayak Jai Prakash (LNJP) hospital were receiving free HAART, while patients at All India Institute of Medical Sciences (AIIMS) had to bear out-of-pocket expenses for HAART. Adherence was defined as not having missed even a single pill over the previous 4-day period on self-reporting. Results: Adherence at AIIMS was 47%, whereas it was 90% at LNJP. The difference was statistically significant. Multivariate analysis showed that nonadherence was associated with not having been told about the importance of HAART, having to pay out-of-pocket for HAART and reported continued risk behavior post HAART. Conclusion: With the provision of free HAART, adherence is likely to be high. Emphasis should be given on simultaneous recruitment of counselors, and physicians should be made aware about the need to inquire and counsel patients against continued risk behavior.

The 2003 outbreak of Dengue fever in Delhi, India.

Dengue fever (DF) and Dengue hemorrhagic fever (DHF) are widespread in Southeast Asia. An outbreak of DF/DHF in Delhi in 2003 started during September, reached its peak in October-November, and lasted until early December. This study describes the clinical and laboratory data of the 185 cases of DF/DHF admitted to Lok Nayak Hospital, New Delhi. The mean age of the patients was 26 +/- 10 years. Fever was present in all the cases with an average duration of fever being 4.5 +/- 1.2 days with headache (61.6%), backache, (57.8%), vomiting (50.8%) and abdominal pain (21%) being the other presenting complaints. Hemorrhagic manifestations in the form of a positive tourniquet test (21%), gum bleeding and epistaxis (40%), hematemesis (22%), skin rashes (20%) and melena (14%) were also observed. Hepatomegaly and splenomegaly were observed in 10% and 5% of cases, respectively. Laboratory investigations revealed thrombocytopenia (with a platelet count of < 100,000/microl) in about 61.39% of cases, Leukopenia (WBC <3,000/mm2) and hemoconcentration (Hct >20% of expected for age and sex) were found in 68% and 52% of the cases, respectively. The mortality rate was 2.7%. Despite widespread measures taken to control outbreaks of DF, it caused major outbreaks. More stringent measures in the form of vector control, improved sanitation and health education are needed to decrease morbidity, mortality and health care costs caused by a preventable disease.
