Investigating a community-wide outbreak of hepatitis a in India.

Background: There was an outbreak of acute hepatitis in Mylapore village, Kollam district, Kerala, southern India during February to June 2013. An outbreak investigation was initiated with the objective of describing the epidemiological features of the hepatitis outbreak. Materials and Methods: House-to-house visits were undertaken to identify symptomatic cases. The outbreak was described in terms of person, place and time. Hypothesis was generated based on findings from descriptive study, laboratory investigation of water samples, and environmental observations. A case-control study was designed to test the hypothesis. Chi-square test, univariate analysis, and logistic regression to identify the risk factors associated with hepatitis A infection were done. Results: Line list generated consisted of 45 cases. Attack rate was the highest among the age group 15-24 years (4.6%) followed by 5-14 years (3.1%). The geographical distribution of the cases suggested a clustering around the water supply through the pipeline and epidemic curve showed a sharp rise in cases suggestive of a common source outbreak. Water samples collected form pipeline showed evidence of fecal contamination and absence of residual chlorine. In the case-control study, having consumed water from the pipeline (odds ratio: 9.01 [95% confidence interval: 2.16-37.61]) was associated with the hepatitis A cases. Conclusion: The time frame of disease occurrence, environmental observations, anecdotal evidences, laboratory results and results of the analytical study indicated the possibility of occurrence of hepatitis A outbreak as a result of pipe water contamination supplied from a bore well. The study warrants establishment of an efficient water quality surveillance system.

Foot care knowledge and practices and the prevalence of peripheral neuropathy among people with diabetes attending a secondary care rural hospital in southern India

Background: Diabetes mellitus is a multifaceted disease and foot ulceration is one of its most common complications. Poor foot care knowledge and practices are important risk factors for foot problems among people with diabetes. Aims: To assess the knowledge and practices regarding foot care and to estimate the proportion of people with peripheral neuropathy among people with diabetes. Settings and Design: The cross-sectional study was conducted in 212 consecutive diabetes patients attending the out-patient department of a rural secondary care hospital. Materials and Methods: A questionnaire which included demographic details, knowledge questionnaire, and Nottingham assessment of functional foot care was administered. The Michigan Neuropathy Screening Instrument was used to identify peripheral neuropathy. Statistical Analysis Used: Descriptive analysis with frequency distribution for knowledge and practice scores, univariate analysis, and multiple logistic regressions to find significant variables associated with good knowledge and practice scores. Results: About 75% had good knowledge score and 67% had good foot care practice score. Male gender (OR 2.36, 95% CI 1.16–4.79), poor education status (OR 2.40, 95% CI 1.19–4.28), and lesser duration of diabetes (OR 2.24, 95% CI 1.15–4.41) were significantly associated with poor knowledge on foot care. Poor knowledge was associated with poor foot care practices (OR 3.43, 95% CI 1.75–6.72). The prevalence of neuropathy was 47% (95% CI 40.14–53.85) and it was associated with longer duration of the disease (OR 2.18, 95% CI 1.18–4.04). Conclusion: There exist deficiencies in knowledge and practices regarding foot care. Male gender, low education, and lesser duration of diabetes are associated with poor knowledge scores. The prevalence of diabetic peripheral neuropathy is high.

Kikuchi-Fujimoto disease: Clinical and laboratory characteristics and outcome

Introduction: Kikuchi-Fujimoto disease is an uncommon disorder with worldwide distribution, characterized by fever and benign enlargement of the lymph nodes, primarily affecting young adults. Awareness about this disorder may help prevent misdiagnosis and inappropriate investigations and treatment. The objective of the study was to evaluate the clinical and laboratory characteristics of histopathologically confirmed cases of Kikuchis disease from a tertiary care center in southern India. Materials and Methods: Retrospective analysis of all adult patients with histopathologically confirmed Kikuchis disease from January 2007 to December 2011 in a 2700-bed teaching hospital in South India was done. The clinical and laboratory characteristics and outcome were analyzed. Results: There were 22 histopathologically confirmed cases of Kikuchis disease over the 5-year period of this study. The mean age of the subjects’ was 29.7 years (SD 8.11) and majority were women (Male: female- 1:3.4). Apart from enlarged cervical lymph nodes, prolonged fever was the most common presenting complaint (77.3%). The major laboratory features included anemia (54.5%), increased erythrocyte sedimentation rate (31.8%), elevated alanine aminotransferase (27.2%) and elevated lactate dehydrogenase (LDH) (31.8%). Conclusion: Even though rare, Kikuchis disease should be considered in the differential diagnosis of young individuals, especially women, presenting with lymphadenopathy and prolonged fever. Establishing the diagnosis histopathologically is essential to avoid inappropriate investigations and therapy.

Quality of life of a patient with type 2 diabetes: A cross-sectional study in Rural South India

Background: With a high prevalence of diabetes in India, there is a need to study the impact of this disease on the quality of life (QoL) of the patients. Materials and Methods: This facility-based cross-sectional study assessed the QoL of patients attending the diabetic clinic using the World Health Organization (WHO) QoL BREF instrument in Tamil Nadu. The QoL was analyzed domain-wise and various socio-demographic factors affecting the QoL were studied. Results: The mean total score of the QoL scale was 58.05 (95% CI, 22.18–93.88). Domain-wise, 63% had good physical, 69% had good psychological, 27% had good social and 85% had good environmental QoL scores. Males, currently married and those with BMI more than 25 had a statistically significantly better QoL compared to their counterparts. Conclusions: Diabetes does impair the QoL of patients but not to a great extent. There is a need to specifically target and improve the QoL of women, widowed and separated, and non-obese diabetics who are at risk of a poor QoL. QoL assessment should be routinely practiced in diabetic clinics.

Determinants of postpartum anemia among women from a rural population in southern India.

Background Even though the problem of anemia during pregnancy has been adequately emphasized, very little attention has been paid to postpartum anemia. The objective of the current study was to estimate the mean change in maternal hemoglobin from 36 weeks’ gestation to 6 weeks postpartum and to identify the factors associated with anemia during the postpartum period among women in a rural development block in Tamil Nadu, India. Methods Ninety-three pregnant women were interviewed using a structured questionnaire at 36 weeks’ gestation and then at 2 and 6 weeks postpartum. Blood samples were collected from the participants at 36 weeks’ gestation and at 6 weeks postpartum. Paired t-tests assessing the difference in mean hemoglobin prepartum and postpartum, univariate analysis, and multiple logistic regression to identify factors associated with postpartum anemia were done using Statistical Package for the Social Sciences version 12 for Microsoft Windows software. Results The proportion of study subjects who were anemic (hemoglobin <11 g/dL) at 36 weeks’ gestation was 26.8% and at 6 weeks postpartum was 47.3% (hemoglobin <12 g/dL). The mean hemoglobin at 36–38 weeks’ gestation was 11.70±1.43 g/dL and at 6 weeks postpartum was 12.10±1.27 g/dL. Anemia at 36 weeks’ gestation (odds ratio [OR] 10.47, 95% confidence interval [CI] 2.37–42.34), heavy blood loss perceived by the mother during delivery (OR 12.91, 95% CI 2.01–61.25), younger maternal age (<21 years, OR 2.45, 95% CI 1.28–23.86), and inadequate iron supplementation during the postpartum period (OR 3.53, 95% CI 1.18–11.37) were identified as significant factors associated with anemia at 6 weeks postpartum. Conclusion Anemia during the third trimester of pregnancy, heavy bleeding perceived by the mother during delivery, younger maternal age, and inadequate iron supplementation during the postpartum period were associated with postpartum anemia.

Risk of developing adulthood obesity among females born with low birth weight: Results from a non-concurrent study from rural Southern India.

Objective: To determine the relationship between birth weight and the evolution of obesity in adult life in women from a rural developmental block in southern India. Design: Non-concurrent cohort Setting: General community- a rural developmental block in southern India. Participants: Two hundred and seventy one young healthy females were recruited from a birth cohort. The study subjects were 98 women in the age group of 19-23 years who had been born with low birth weight (LBW) and 173 women in the same age group who had been born with normal birth weight (NBW). Materials and Methods: Data collection involved interview using a structured questionnaire and anthropometric measurements. Analysis: Chi-square test to assess significance of association, independent sample t test to assess the difference between means, odds ratios for measuring magnitude of association, stratified analysis to identify various interactions and confounders, and multiple logistic regression models to identify the relationship between birth weight and young adult obesity (BMI > 25). Results: A crude odds ratio of 0.564 (95% CI 0.262 - 1.214) was obtained for the association between LBW and development of obesity later in life. In the final logistic regression model, it was found that a young adult female with low birth weight who belonged to a higher socio-economic group had a higher risk of developing obesity (Adjusted odds for the interaction term between LBW and high SES 6.251; 95% CI 1.236 - 31.611). Conclusion: The study could not find any significant association between LBW and development of obesity later in life, but it found a higher probability of developing obesity later in life among low birth weight female children born in high socio-economic status families.

Quality-of-life among elderly with untreated fracture of neck of femur: A community based study from southern India

Background and Objectives: Owing to the high prevalence of osteoporosis and falls, elderly people are at risk of developing hip fractures. The objective of the current study is to assess the quality-of-life (QOL) of elderly (>60 years) with untreated hip fractures in a rural developmental block in Southern India. Methodology: Twenty-one elderly with an untreated fracture neck of femur were identified with the help of community level health workers. EuroQol (EQ-5D) was administered to assess the QOL before and after the event. QOL was also assessed among a comparison group, matched for age and sex among neighborhood people. Wilcoxon signed rank test and Mann-Whitney U test were used to compare EQ-5D mean scores with before the event scores and the comparison group scores respectively. Results: Of people with hip fracture, 57.1% (12/21), 76.2% (16/21), 81% (17/21), 52.6% (11/21) and 85.7% (18/21) reported severe problems with mobility, pain, usual activity, self-care and anxiety respectively. The EQ-5D mean score among the elderly with fracture neck of the femur was 0.08 (SD 0.27). It was low when compared with the same subjects before the occurrence of the event (Z −4.05, P < 0.001) and as compared with the comparison group (Z −5.77 P < 0.001). Conclusion: The QOL scores assessed using EQ-5D index scores was poor among people with untreated fracture neck of the femur as compared with the comparison group and also as compared to their status before the occurrence of the event. A vast majority of study participants reported severe problems with mobility, pain, usual activity and self-care and anxiety domains of EQ-5D questionnaire.

Awareness of health care workers, patients and visitors regarding air borne infection control – A descriptive study from a Tertiary Care Centre in Kerala, southern India

Airborne infections are major public health concern especially in hospitals and public spaces in a highly populated country like India. Generating awareness about good infection control practices among common man and health care workers are important steps in curtailing transmission of air borne infections. In this study we were trying to assess the awareness of airborne infection control measures among patients, bystanders and healthcare workers in a tertiary care hospital at Kochi, Kerala. Self-administered questionnaire which included 10 questions for health care staff and 12 questions for lay men prepared on the basis of NAIC and NCDC guideline were given to the study participants. 143 health care staff and 332 laymen were participated in the study. In both groups majority of the responses were correct. However, only a small proportion of health care staff correctly answered fast tracking of a patient with TB (14.7%) and minimum air exchanges in air-conditioned settings (15.4%). Among laymen only a few correctly identified ideal place for sputum collection (43.3%) and role of hand washing in preventing flu (36.4%). Overall more intervention needed in improving awareness about good infection control practices among both health care staff and laymen.

Prevalence of exposure to secondhand smoke among higher secondary school students in Ernakulam District, Kerala, Southern India

Introduction: The association between secondhand smoke and health outcomes, such as frequent respiratory infections, ischemic heart disease, lung cancer, asthma, and stroke, has long been established. The study aimed to estimate the prevalence of secondhand smoking exposure among higher secondary school students in Ernakulam district, Kerala, Southern India. Materials and Methods: A structured questionnaire was administered to all students from four randomly selected higher secondary schools in Ernakulam district. Descriptive statistics was done using frequencies and percentages. Univariate and multivariate analyses were done for factors associated with household exposure to tobacco smoke generating odds ratios (ORs) and 95% confidence intervals (CIs). Results: A total of 629 students participated in the study. The prevalence of ever smokers was 11.9% and of current smokers was 5.2%. Among the study participants, 23.2% were exposed to secondhand smoking from a family member and 18.8% from friends. Lower educational status of father was associated with the household exposure to secondhand smoke (adjusted OR 4.51 [95% CI 1.66–12.22]). More than half of the study participants (56.3%) reported that they were exposed to cigarette smoke in past 1 week in a public place and 10.2% in closed public places. Nearly one-third of the students reported that they have seen somebody smoking inside school campus in the past 30 days. Conclusion: Exposure to secondhand smoke at home, schools, and public places was higher among the late adolescent higher secondary school students in Ernakulam district. The findings underscore the urgent need for increased efforts to implement the strategies to reduce secondhand smoke exposure among adolescents.

Investigation of an Outbreak of Hepatitis A in a Coastal Area, Kerala, Southern India

An outbreak investigation was initiated following an unusual occurrence of hepatitis A reported among people residing in the coastal belt of Vadi to Vedikunnu area, Kollam district, Kerala, southern India. The time frame of disease occurrence, pattern of its distribution, and the incubation period of hepatitis A infection indicated the probability of occurrence of the outbreak as a result of pipe line water contamination due to mixing of sewage from a canal. The results add evidence to the epidemiology of hepatitis A in the state and warrant the establishment of an efficient water quality surveillance system.
