BACKGROUND: Men who have sex with men and transgenders are an important risk group for sexually transmitted infections (STIs) and human immunodeficiency virus (HIV). They have risky sexual behaviors but low risk perception. OBJECTIVES: To assess the sexual behavior, STIs, HIV and identify factors associated with HIV in men who have sex with men (MSM) and transgenders (TGs) in Mumbai. METHODS: Participants were enrolled from two clinics in Mumbai. They completed an interviewer-administered questionnaire and were evaluated for STIs and HIV infection. RESULTS: A total of 150 participants, 122 MSM and 28 TGs were evaluated; 17% of MSM and 68% of the TGs were HIV infected. HIV infection in MSM was associated with serological positivity for HSV2 IgG [adjusted odds ratio (aOR), 95% confidence interval (CI): 9.0 (2.2-36.9)], a positive Treponema pallidum hemagglutination assay (TPHA) [aOR (95% CI): 6.0 (1.5-24.0)], greater than five acts of receptive anal sex in the past six months [aOR (95% CI): 4.3 (1.2-15.0)] and per category increase in age (18-24 yrs, 25-29 yrs, > 30 yrs) [aOR (95% CI): 3.1 (1.3-7.1)] in multivariate analysis. Consistent condom use during receptive anal sex in the past six months was low (27%). Many MSM were married (22%) or had sex with females and may act as a 'bridge population'. HIV infection in TGs was associated with a positive TPHA [OR (95% CI): 9.8 (1.5-63.9)] and HSV 2 IgG [OR (95% CI): 6.7 (1.1-40.4)] in univariate analysis. CONCLUSION: Prior STIs were strongly associated with HIV infection in MSM and TGs. These groups should be the focus of intensive intervention programs aimed at STI screening and treatment, reduction of risky sexual behavior and promotion of HIV counseling and testing.
Sputum samples from 100 patients of pulmonary tuberculosis were processed. These patients were admitted in group of Tuberculosis Hospital at Sewri, Mumbai, which is a referral tuberculosis hospital. Isolates were identified as M. Tuberculosis by biochemical tests. Antitubercular sensitivity testing for Isoniazid, Rifampicin, Ethambutol and Streptomycin was performed by resistance ratio method. Total resistance was 36% in our study. Resistance to Isoniazid was 61%: to Rifampicin was 50%, to Ethambutol was 8% and to Streptomycin was 41%. Primary drug resistance to Isoniazid was 45% to Rifampicin was 27%, to Ethambutol was 9%, and to Streptomycin was 54%. Secondary drug resistance to Isoniazid was 68% to Rifampicin was 60%, to Ethambutol was 8% and to Streptomycin was 36%. Secondary drug resistance to Isoniazid and Rifampicin is rising as compared to primary drug resistance to Isoniazid and Rifampicin. This is statistically significant (p < 0.001). 11 out of 36 cases (30%) showed multi drug resistance to Isoniazid and Rifampicin.
Of 93 blood cultures received with a suspicion of anaerobic bacteraemia over a period of two years, only 17 (18.3%) showed anaerobic growth. Twelve grew anaerobes alone while five had a polymicrobial flora. Seven of these patients (4.3%) had pre-existing heart disease while others had history of prior surgery, diabetes mellitus or urinary tract infection. Oropharynx was the commonest portal of entry, followed by gastrointestinal tract. The anaerobes isolated were anaerobic streptococci, Bacteroides fragilis group and Bilophila and Eubacterium species. Fifteen patients developed major complications such as congestive cardiac failure, systemic embolisation, and perforative peritonitis. The mortality rate among the cases with anaerobic bacteraemia was 23.5% in this study.
Acanthamoeba keratitis, common in soft lens wearers, is not commonly isolated. The reports of Acanthamoeba keratitis in Indian literature are few. We report here a case of Acanthamoeba Keratitis in a medical student using soft contact lenses, initially diagnosed and treated as a bacterial and later as a viral corneal ulcer, who responded extremely well to medical line of therapy.
Viability status before and after treatment with antibiotics was investigated in a total of 104 homograft valves using MTT (3-[4, 5-dimethyl thiazol-2-y1]-2, 5-diphenyl tetrazolium bromide). The valves with warm ischaemic time above 11 hours, were found to be non-viable. Increase in storage time directly decreases cell viability. Methyl thiazol tetrazolium (MTT) assay can be used as a reliable, simple, rapid and economic method for assessing the viability status based on mitochondrial respiration even for homograft valves. Basal media with and without nutrients i.e., DMEM and Hanks BSS showed no difference in viability of the cells.
