The seroprevalence of Japanese encephalitis virus (JEV) among equines was evaluated from January 2006 to December 2009 in 13 different states of India by hemagglutination inhibition (HI) test and virus neutralization test (VNT). Antibodies against JEV were detected in 327 out of 3,286 (10%) equines with a maximum prevalence reported in the state of Manipur (91.7%) followed by Gujarat (18.5%), Madhya Pradesh (14.4%), and Uttar Pradesh (11.6%). Evidence of JEV infection was observed in equines in Indore (Madhya Pradesh) where a 4-fold or higher rise in antibody titer was observed in 21 out of 34 horses in November 2007 to October 2006. In March 2008, seven of these horses had a subsequent 4-fold rise in JEV antibody titers while this titer decreased in nine animals. JEV-positive horse sera had a JEV/WNV (West Nile virus) ratio over 2.0 according to the HI and/or VNT. These results indicated that JEV is endemic among equines in India.

BACKGROUND:
Tobacco consumption causes almost 638,000 premature deaths per year in India. This study sought to examine the prevalence and determinants of tobacco use among men in India.
METHODS:
We analyzed data from the fourth round of the National Family Health Survey in India. These nationally representative cross-sectional sample data were collected from January 20, 2015, to December 4, 2016. A total of 112,122 men aged 15-54 years were included in this study. Primary outcomes were tobacco use categorized into smoking, smokeless, any tobacco, and both smoked and smokeless tobacco use. Complex survey design and sampling weights were applied in both the descriptive analyses and logistic regression models. We present the findings using odds ratios.
RESULTS:
The prevalence of tobacco use among men in India for the studied period was 45.5% (95% CI 44.9-46.1), smoking was 24.6% (95% CI 24.1-25.1), smokeless tobacco use was 29.1% (95% CI 28.6-29.6), and both smoked and smokeless tobacco use was 8.4% (95% CI 8.1-8.7). The prevalence of tobacco use among men was higher among the elderly, separated/divorced/widowed individuals, those with lower education and wealth status, alcohol consumers, manual workers, and residents of the northeast region. Multivariate analysis showed that age, lower education, occupation, region, alcohol consumption, separated/divorced/widowed status, and economic status were substantially associated with tobacco use among Indian men.
CONCLUSIONS
Innovative and cost-effective strategies targeting high-risk groups are crucial to curbing the tobacco epidemic in India. Anti-smoking campaigns should also focus on mitigating alcohol abuse. Reducing tobacco marketing and implementing formal education about the dangers of tobacco use, progressive taxing, packaging, and labeling of tobacco products and price strategies should be harmonized in legal provisions.

AIMTo determine whether there was any regional variation in the prevalence of azoospermia, oligozoospermia and mean sperm counts in male partners of infertile couples from different parts of India.
METHODSData on 16,714 semen samples analyzed over the past five years from six different laboratories located in five cities of India were collated and evaluated.
RESULTSThere was a regional variation in the prevalence of azoospermia. The prevalence of azoospermia was extremely high in Kurnool and Jodhpur (38.3% and 37.4%, respectively). There was also a regional variation in the prevalence of oligozoospermia (51%) in Kurnool. There was no significant difference in the mean sperm counts in normospermic men.
CONCLUSIONThere is a regional variation in the prevalence of azoospermia and oligozoospermia in the male partners of infertile couples from different regions of India. The prevalence of azoospermia in Kurnool and Jodhpur is higher than any other worldwide reported literature. Further studies need to be carried out to determine the cause of this.

India is home to the world's second largest population. Rheumatology is an emerging specialty in India. We reviewed organization, epidemiology and training facilities for Rheumatology in India. Also, we also looked at publications in the field of rheumatology from India from over the past six years using Scopus and Medline databases. Despite rheumatologic disorders affecting 6%-24% of the population, rheumatology in India is still in its infancy. Till recently, there were as few as two centers in the country training less than five fellows per year. However, acute shortage of specialists and increasing patient numbers led to heightened awareness regarding the need to train rheumatologists. Subsequently, six new centers have now started 3-year training programs in rheumatology. The epidemiology of rheumatic diseases in India is being actively studies under the Community Oriented Programme for Control of Rheumatic Diseases (COPCORD) initiative. The most number of publications on rheumatic diseases from India are on rheumatoid arthritis, lupus and osteoporosis, many of which have been widely cited. Major collaborators worldwide are USA, UK and France, whereas those from Asia are Japan, Saudi Arabia and Singapore. The Indian Rheumatology Association (IRA) is the national organization of rheumatologists. The flagship publication of the IRA, the Indian Journal of Rheumatology, is indexed in Scopus and Embase. To conclude, rheumatology in India is an actively expanding and productive field with significant contributions to world literature. There is a need to train more personnel in the subject in India.

The vir genes are antigenic genes and are considered to be possible vaccine targets. Since India is highly endemic to Plasmodium vivax, we sequenced 5 different vir genes and investigated DNA sequence variations in 93 single-clonal P. vivax isolates. High variability was observed in all the 5 vir genes; the vir 1/9 gene was highly diverged across Indian populations. The patterns of genetic diversity do not follow geographical locations, as geographically distant populations were found to be genetically similar. The results in general present complex genetic diversity patterns in India, requiring further in-depth population genetic and functional studies.

PURPOSEOcular trauma is one of the most common causes of acquired blindness in children. It measures about 8%-14% of total childhood injuries. This study aims to determine the epidemiological profile of ocular trauma in the pediatric age group attending a tertiary hospital in northern India.
METHODSA retrospective study was conducted in our hospital between June 2014 to July 2015 and all the children aged 0-16 years presenting with ocular trauma in eye outpatient department and emergency were enrolled in the study. Various epidemiological parameters like age, sex distribution, duration of presentation, mode of injury, type of injury and final visual outcome were analyzed.
RESULTSOf total 357 patients, 271 (76%) were below the age of 12 years; 41.1% of children with ocular trauma belonged to age group 2-6 years. The male to female ratio was 2.9:1. Out of total patients, 242 (67.8%) presented with closed globe injury. Among the closed globe injury, the history of fall was present in about 35% of children, followed by trauma while playing with bat/ball (15.7%) and finger nail trauma (13.2%). Among open globe injury, trauma with needle, knife, glass and pen were common causes. Home was the most common place of injury (47.8%), followed by streets (17.9%) and playground (14.9%).
CONCLUSIONChildren are vulnerable to ocular trauma and need more supervision. Sharp objects like needles, knives, household chemicals like acids should be out of reach of children.

OBJECTIVETrauma in India is an increasingly significant problem, particularly in light of rapid development and increasing motorization. Social changes are resulting in alterations in the epidemiology of trauma. The aim of the study was to assess the various epidemiological parameters that influence the cause of injury in the patients admitted to a major trauma centre in northern India.
METHODSAn observational study of 748 patients chosen by random assortment was carried out over a period of 1 year (August 2008 to July 2009). Age, sex, injury type and pattern were noted. Injury mode of upper and lower limbs was also noted.
RESULTSInjuries occur predominately in the age group of 15-30 years. Males incurred more injury with male to female ratio of 6:1. The most vulnerable group was motorcycle users. Among the injured, farmers were the most commonly involved. Blunt injuries (94.92%) were much more common than penetrating injuries. Among patients with head injury, two-wheeler related accidents were the most common (40.3%). Most spinal cord injuries were caused by falls from height (51.09%). Most lower limb fractures were simple type. Compound fractures of the lower limb were more common than upper limb fractures.
CONCLUSIONStrict enforcement of traffic rules, combined with improved infrastructure and behavior change can decrease the burden of road traffic accidents in India and other developing countries. This study could assist in raising the profile of road traffic accidents as a public health problem which needs to be addressed as a preventable cause of mortality and morbidity, and planning appropriate interventions for this major challenge. Preventive strategies should be made on the basis of these epidemiological trends.

Nasopharyngeal cancer (NPC) is a rare disease in most parts of the world, except for Southeast Asia, some parts of North Africa and the Arctic. It is mostly seen in people of Chinese origin. In India, NPC is also rare, except for the Hill States of Northeast India, particularly Nagaland, Manipur, and Mizoram. The striking feature of NPC in Northeast India is that the incidence ranges over the complete spectrum from the lowest (as 0.5/100 000 to 2.0/100 000 among Caucasoid) to the highest (as about 20/100 000 among Cantonese/Zhongshan dialect Chinese). The age-adjusted rate of NPC in Kohima district of Nagaland State is 19.4/100 000, which is among the highest recorded rates. By contrast, in Assam, one of the so-called Hill States but not itself a hilly state, NPC is much less common. The Northeastern region is distinguished by a preponderance of the Tibeto-Burman languages and by variable mongoloid features among peoples of the region. The nature of the migratory populations who are presumed to be bearers of the mongoloid risk is unknown, but these NPC occurrence features provide an outstanding opportunity for NPC risk investigation, such as that of the hypothesis of Wee et al. for westward displacement of Chinese aborigines following the last glacial maximum.

INTRODUCTIONThis study was conducted to determine the epidemiological pattern and risk factors associated with corneal ulcers in rural areas of western Maharashtra, India, and to identify the bacterial and fungal agents responsible for causing keratitis.
METHODSA total of 852 patients with corneal ulceration were included in the study. Sociodemographic data and information pertaining to risk factors were collected. Corneal scrapings obtained from these patients were processed for bacterial and fungal agents using standard techniques.
RESULTSOut of the 852 patients studied, 537 (63.02%) were culture positive. A majority of the culture-positive patients were farmers (52.32%), and ocular trauma was the most common predisposing factor (60.15%). Among these patients, fungal isolates (57.91%) were more frequent than bacterial isolates (42.08%). The most common fungal isolate was Fusarium spp. (35.04%) followed by Aspergillus spp. (18.00%). Streptococcus pneumoniae was the predominant bacterial isolates (32.74%) followed by Staphylococcus spp. (17.25%).
CONCLUSIONCorneal trauma from plant parts or organic matter was found to be the most common risk factor associated with corneal ulceration in the rural areas of western Maharashtra. Epidemiology and aetiology of microbial keratitis vary from region to region, and therefore, careful history taking and proper identification of aetiological agents are necessary for the institution of appropriate therapy.
