Hidden leprosy cases in tribal population groups and how to reach them through a collaborative effort.

BACKGROUND: Tribal populations are an underserved population group and access to health services is a major challenge for them. Since leprosy treatment is integrated with the general health services, identifying leprosy cases is not be easy in these settings and they remain as endemic reservoirs, unless greater efforts are made to reach them. METHODOLOGY: An active search operation was conducted in the tribal colonies in four pre-identified Health & Nutrition Clusters, Nellore district, Andhra Pradesh, India, in 2013. After a brief training, village health nurses and selected volunteers covered all the households, showing flash cards with photos of leprosy cases and enquiring if there was any resident with a similar condition. Suspects were listed and examined by the district leprosy supervisor and field coordinators from Damien Foundation. Follow up interviews were done after one year to assess the treatment completion rate. RESULTS: Village health workers covered 47,574 people living in the tribal colonies and identified 325 leprosy suspects. Among them, 70 were confirmed as new leprosy cases. The prevalence of previously undetected leprosy cases was found to be 14.7/10,000. Out of 70 cases, 19 (27%) were children, 35 (50%) were female, 32 (45.7%) were classified as MB leprosy, 6 (8.6%) had a leprosy reaction and 11 (15.7%) persons had Grade 2 disability at the time of diagnosis. The treatment completion rate was found to be 74% at the end of one year. CONCLUSION: The study reveals a very high burden of leprosy among the tribal population and demonstrates how resources can be mobilized from government, NGO and local community sources to promote early case detection among underserved population groups.

Conservation of an endemic medicinal plant, Berberis tinctoria Lesch. In Nilgiris through micro propagation.

Berberis tinctoria Lesch. Is an endemic plant to high hills of Nilgiris having lot of medicinal properties. For its better conservation through mass multiplication, attempts have been made to standardize tissue culture technology. The results of the study exhibited that the basal medium containing BAP and NAA each at 0.5 mg/1 was found to be the optimum for callus formation. Shoot proliferation was highly effective in the basal medium supplemented with BAP at 0.5 mg/1. The root initiation was maximum in the basal medium containing the NAA at 1.0 mg/1 and the plantlet establishment was successful in the hardening medium composed by vermiculite and soil in the ration of 1:1.

Influence of monosaccharides on the fibrillogenesis of type I collagen.

The in vitro self-assembly of Type I rat tail tendon collagen in the presence of monosaccharides was studied turbidimetrically. D(+)glucose and D(+)mannose delayed fibril formation significantly while D(-)fructose showed no variation. The effect of glucose was concentration dependent. Binding of glucose during fibrillogenesis was shown by the incorporation of [14C]glucose and also by SDS-polyacrylamide slab gel electrophoresis of the product. The results indicate that in vitro nonenzymatic glycosylation can take place in the short duration required for fibril formation.
