Background: Harmful use of alcohol is one of the globally recognized causes of health hazards. There are no data on alcohol consumption from Andaman and Nicobar Islands.

Objective: The objective of the study was to assess the prevalence and pattern of alcohol use among the population of Andaman and Nicobar Islands, India.

Nutritional Status of Preschool Children in Andaman and Nicobar Islands and Food Insecurity, Food Groups, and Nutrient Consumption among Population.

Background: Childhood undernutrition is a public health concern in India. But on such a serious issue, there are no data available from the Union Territory of Andaman and Nicobar (A and N) Islands.

Objectives: Present study was designed to know the prevalence of food insecurity, to estimate food group and nutrient intake among the community, and undernutrition and clinical signs of micronutrient deficiency among the preschool children of A and N islands.

Tobacco use and nicotine dependency in a cross-sectional representative sample of 18,018 individuals in Andaman and Nicobar Islands, India.

Background: Data on prevalence, pattern of tobacco use, proportion of population dependent on nicotine and their determinants are important for developing and implementing tobacco control strategies. The aim of the study was to estimate the prevalence and determinants of tobacco use and nicotine dependency.

Methods: A cross-sectional survey among a representative sample of 18,018 individuals in the age group of >=14 years was conducted in the Union Territory of Andaman and Nicobar Islands during 2007-09.

Antimicrobial resistance in Shigella--rapid increase & widening of spectrum in Andaman Islands, India.

Background & Objectives: Shigellosis is known to be a major cause of acute childhood diarrhoea in Andaman & Nicobar Islands, India. Rapid emergence of antibiotic resistance warrants continuous monitoring of sensitivity pattern of bacterial isolates. We report here the salient findings of an ongoing study on shigellosis in Andaman Islands, India, with regards to change in drug resistance pattern during the past one decade.

Role of proinflammatory cytokines and chemokines in chronic arthropathy in CHIKV infection.

Chikungunya virus (CHIKV) has caused large outbreaks worldwide in recent years. Acute-phase CHIKV infection has been reported to cause mild to severe febrile illness, and in some patients, this may be followed by long-lasting polyarthritis. The mainstay of treatment includes nonsteroidal anti-inflammatory drugs and other disease-modifying agents, the use of which is based on the assumption of an immunological interference mechanism in the pathogenesis.

Association of hypertension with risk factors & hypertension related behaviour among the aboriginal Nicobarese tribe living in Car Nicobar Island, India.

Background & Objectives: There are no composite estimates on prevalence of hypertension among indigenous tribes in India. The present study was carried out to estimate the prevalence of hypertension, its association with determinants, and to assess the hypertension related behaviour of the Nicobarese aborigines.

Methods: This cross-sectional survey was carried during 2007 and 2009.

Rapid emergence of third-generation cephalosporin resistance in Shigella sp. isolated in Andaman and Nicobar Islands, India.

Shigellosis is a major cause of diarrheal diseases among children in Andaman & Nicobar Islands, India, which have a population of 350,000 people, including settlers from mainland India and 6 indigenous tribes. From the last one-and-half decade, we have been monitoring the species distribution and emergence of antibiotic resistance among the isolates of Shigella. The circulating Shigella strains have been found rapidly acquiring resistance to a wide spectrum of antibiotics.

Tsunami, post-tsunami malaria situation in Nancowry group of islands, Nicobar district, Andaman and Nicobar Islands.

Background & Objectives: Due to tsunami in 2004 a large proportion of population in Nicobar group of Islands become homeless, and in 2006 large scale labour migration took place to construct the houses. In 2008, a significant increase in malaria incidence was observed in this area. Therefore, in March 2008, the situation of malaria was assessed in Nancowry Islands in Nicobar District to study the reasons for the observed upsurge in the number of cases, and to suggest public health measures to control the infection.

Outbreak of chikungunya fever, Dakshina Kannada District, South India, 2008.

The outbreak of chikungunya fever that surfaced in India during late 2005 has affected more than 1.56 million people, spread to more than 17 states/union territories, and is still ongoing. Many of these areas are dengue- and leptospirosis-endemic settings.

Clinical progression of chikungunya fever during acute and chronic arthritic stages and the changes in joint morphology as revealed by imaging.

This longitudinal follow-up study of 203 patients with serologically confirmed chikungunya (CHIK) virus infection describes the clinical features of CHIK fever during the first and tenth months of illness. During the acute stage CHIK fever presents with a wide array of symptoms. The foremost chronic symptoms at the end of a month were rheumatism (75%) and fatigue (30%).
