An FGD Report on Vitamin B12 Deficiency in Medical Professionals.

Introduction: Vitamin B12 Deficiency has become animportant health concern in the recent times. Acknowledgingthe health of medical professionals shall improve the healthstatus of the community as they form a classified population ofthe society. The present study was done with an aim to assessthe treatment seeking behavior of the doctors in RNT MedicalCollege, Udaipur who were found deficient in Vitamin B12levels.Material and methods: Two focused group discussionswere conducted in the department of Community Medicinewith a strength of 13 and 17 each, few pre-decided questionswere asked to the groups by the moderator and answers werereported by the recorder in the form of tally sheets.Results: Maximum doctors were interested in taking Oraltreatment by self, most of them were consuming ReverseOsmosis water and most common clinical feature theyexpressed were weakness and fatigue.Conclusion: Vitamin B12 deficiency is becoming a silentepidemic which needs to be addressed as it is affecting all thegroups of the society and thus further large scale multicentricstudies are needed to address this issue at the global level.

Entomological studies for surveillance and prevention of dengue in arid and semi-arid districts of Rajasthan, India.

BACKGROUND & OBJECTIVES: Rajasthan is one of the dengue endemic states of India. Very few studies have been published on entomological aspects of dengue in this state. Owing to water scarcity, inhabitants in desert areas overstore domestic water which leads to the persistence of dengue vectors within the domestic premises. Area specific knowledge on breeding, key containers and seasonal rhythms of vector population is essential for preparing an effective prevention plan against dengue. Present paper reports results of entomological investigations on dengue vectors in arid and semi-arid districts of Rajasthan. METHODS: Longitudinal studies were undertaken during 2004-06 in one arid and two semi-arid dengue endemic districts of Rajasthan. Adult and larval Aedes were collected from the randomly selected houses in representative towns and villages with associated details of container types and water storage practices of inhabitants. RESULTS: In urban areas during all the seasons adult house index (AHI) of Aedes aegypti was maximum in desert zone (25) and least in semi-arid area with saline river III (1). The difference of AHI during three seasons was statistically significant (chi2 = 16.1, p < 0.01 for urban; and chi2 = 50.71, p < 0.001 for rural). Breeding of Ae. aegypti among urban settings was maximum in desert zone. During all the seasons cement tanks were the key breeding habitats for Ae. aegypti in desert as well as semi-arid areas. INTERPRETATION & CONCLUSION: Water storage habits during summer season emerged to be the risk factor of vector abundance in urban areas of arid and semi-arid settings. A carefully designed study of key containers targeting cement tanks as the primary habitats of mosquito control may lead to commendable results for dengue prevention.

Entomological studies on malaria in irrigated and non-irrigated areas of Thar desert, Rajasthan, India.

BACKGROUND & OBJECTIVES: Malaria is the major health problem in western Rajasthan yet its vector fauna and transmission dynamics thereof is not understood properly. The present investigations report complete profile of qualitative and quantitative aspects of anopheline species occurring in different settings of desert ecosystem. METHODS: Area with irrigation through canal for more than 20 years (setting I), area with irrigation through canal for 10 years (setting II) and area without any irrigation (setting III) have been selected for studies. Species identification and their densities (per man hour) was made as per standard methods. RESULTS: In village of setting I, during rainy season, An. subpictus and An. stephensi were present while during winter season four species--An. subpictus, An. stephensi, An. culicifacies and An. annularis were collected. In all the villages of setting I, II and III no Anopheles mosquito was observed during summer season. In the villages of desert region without any irrigation facilities through any canal, the anopheline species were present only during rainy season. INTERPRETATION & CONCLUSION: An. stephensi is the major malaria vector of desert irrespective of whether the area is canal irrigated or not. During summer season absence of vector species in all the villages require further studies on micro-ecology of the species under desert conditions.
