In the Indian population, the prevalence of resistance of H. pylori is very high to metronidazole, moderate to clarithromycin and amoxycillin and low to ciprofloxacin and tetracycline. The rate of resistance was higher in southern India than in northern India. The E-test emerges as a reliable quantitative antibiotic susceptibility test. A change in antibiotic policy to provide scope for rotation of antibiotics in the treatment of H. pylori in India is a public health emergency.

Liver abscesses are frequently observed in pediatric clinical practice in tropics and subtropics especially in developing countries. Children have unique set of predisposing factors which have been highlighted. Expected microbiology and setting for unusual organisms are mentioned. Clinical presentations', including importance of location and number of abscesses has been discussed. Role of each modality of treatment clarified. Importance and limitations of investigations and imaging explained and complications and mortality discussed.

This facility-based cross-sectional study was conducted to determine the patterns of disclosure of HIV positive serostatus among 145 Indian children aged >5 years. Only 60 (41.4%) children were aware of their HIV-positive status. Disclosure was most frequently done by parents [51/60 (85%)] at a mean age of 9.1 ± 1.4 years. The rate of inaccurate disclosure was high [64/85 (75.3%)]. No information regarding their illness was given to 21/85 (24.7%) children. The most common reason for non-disclosure was that the child is too young [79/85 (92.9%)]. The factors favoring disclosure were increasing duration since diagnosis of HIV infection [odds ratio (OR) = 1.46; 95% confidence interval (CI) 1.11-1.93], non-perinatal mode of transmission (OR = 6.14; 95% CI 2.01-15.80), ART initiation (OR = 3.05; 95% CI 1.33-7.01), school enrolment (OR = 3.52; 95% CI 1.44-7.57) and caregiver educated beyond fifth grade (OR = 2.69; 95% CI 1.21-5.96). Detailed guidelines on disclosure are required focusing on children of school-going age with perinatal infection who are not on ART and with caregivers of low educational status.

This study was conducted to evaluate the comparative effect of yogic and conventional treatment in diarrhea-predominant irritable bowel syndrome (IBS) in a randomized control design. The patients were 22 males, aged 20-50 years, with confirmed diagnosis of diarrhea-predominant IBS. The conventional group (n = 12, 1 dropout) was given symptomatic treatment with loperamide 2-6 mg/day for 2 months, and the yogic intervention group (n = 9) consisted of a set of 12 asanas (yogic poses, i.e., Vajrasana, Shashankasana, Ushtrasana, Marjariasana, Padhastasana, Dhanurasana, Trikonasana in two variations, Pawanmuktasana, and Paschimottanasana) along with Surya Nadi pranayama (right-nostril breathing) two times a day for 2 months. All participants were tested at three regular intervals, at the start of study--0 month, 1 month, and 2 months of receiving the intervention--and were investigated for bowel symptoms, autonomic symptoms, autonomic reactivity (battery of five standard tests), surface electrogastrography, anxiety profile by Spielberger's Self Evaluation Questionnaire, which evaluated trait and state anxiety. Two months of both conventional and yogic intervention showed a significant decrease of bowel symptoms and state anxiety. This was accompanied by an increase in electrophysiologically recorded gastric activity in the conventional intervention group and enhanced parasympathetic reactivity, as measured by heart rate parameters, in yogic intervention group. The study indicates a beneficial effect of yogic intervention over conventional treatment in diarrhea-predominant IBS.

Several new chalcone analogues were synthesized and evaluated as inhibitors of malaria parasite. Inhibitory activity was determined in vitro against a chloroquine-sensitive Plasmodium falciparum strain of parasites. The compound 3-(4-methoxyphenyl)-1-(4-pyrrol-1-yl-phenyl)prop-2-en-1-one was found to be the most active with 50% inhibition concentration (IC 50 ) of 1.61 lg/ml. This inhibitory concentration is comparable to a prototype phytochemical chalcone, licochalcone A, with an IC 50 of 1.43 lg/ml. The present study suggests that small, lipophilic nitrogen heterocyclic ring A together with small hydrophobic functionality at ring B can enhance antimalarial activity. These results suggest that chalcones are a class of compounds that provides an option of developing inexpensive, synthetic therapeutic antimalarial agents in the future.
