Updated BG Prasad socioeconomic classification, 2014: a commentary.

Modified BG Prasad socioeconomic scale is widely used to determine the socioeconomic status of study subjects in health studies in India. It is an income-based scale and, therefore, has to be constantly updated to take inflation and depreciation of rupee into account. The Consumer Price Index (CPI) for industrial workers (IW) is used to calculate updated income categories for January 2014. Details of the calculations involved will enable young researchers to calculate specific income categories for their research work. State-specific CPI values are also available on the Department of Labour website and should be used to determine more accurate income categories for the study area.

Burden among stroke caregivers: results of a community-based study from Kolkata, India.

BACKGROUND AND PURPOSE: Stroke causes significant caregiver (CG) stress, which is under-reported in India. This study assesses the financial, physical, psychological, and family burden on CG of stroke patients in an urban community. METHODS: Cross-sectional survey of stroke patients and CG were selected from a community-based registry using validated scales through face-to-face interviews. RESULTS: Data were available from 199 stroke survivors and a similar number of CG. Increased workload, related anxiety and depression, and sleep disturbance were reported by 70%, 76%, and 43% of CG, respectively, whereas >80% reported financial worry, which was greater among slum dwellers and less educated families. CG of patients with dementia and depression experienced greater stress. Female CG received more appreciation and family bonding was well-maintained. CONCLUSIONS: Financial stress was prominent and common among the socioeconomically weaker section. Psychological stress is similar to that of other studies. Women CG received greater appreciation. Family bonding was well-preserved in contrast to that of a western report.

A longitudinal study of epilepsy in Kolkata, India.

PURPOSE: This study aimed to determine the prevalence, incidence, and mortality rates of epilepsy in the city of Kolkata, India. This is the first such longitudinal study in a heterogeneous urban Indian population. METHODS: A two-stage door-to-door survey of a stratified random sample was undertaken within the municipal limits of Kolkata. Trained field workers detected and interviewed the cases using a simple screening questionnaire, and the detailed follow-up was done by neurologists. The survey was conducted annually for five consecutive years from March 2003 through February 2008. RESULTS: A total of 52,377 (52.74% men) individuals were screened. There were 309 prevalent and 66 incident cases of active epilepsy. The prevalence and average annual incidence rate (AAIR) with 95% confidence interval (CI), age-standardized to World Standard Population, were 572.8 (509.79-641.54) per 100,000 and 27.27 (21.03-34.80) per 100,000 per year, respectively. The age-specific incidence rates of epilepsy showed bimodal distribution. During the 5-year period, 20 cases of active epilepsy died. The average annual mortality rate (AAMR) was 7.63 (95% CI 4.45-11.26) per 100,000 population per year. Compared to the general population of Kolkata, the all-cause standardized mortality ratio (SMR) for persons with epilepsy was 2.58 overall (men 3.67; women 1.77). There was no significant difference between slum and nonslum dwellers in epidemiologic parameters. CONCLUSIONS: The AAIR of epilepsy is comparable to that observed in developed countries, but AAMR is higher. The all-cause SMR for epilepsy relative to the general population is, however, similar to that of developed nations.

Integrated counseling and HIV testing centers of Delhi: An evaluation.

BACKGROUND: HIV counseling and testing services are a key entry point in prevention of HIV infection, treatment, and care of people with HIV. Evaluation of counseling, testing, and referral services help to increase the effectiveness, efficiency, and quality of services delivered by providers by improving any deficiencies in availability, accessibility, and acceptability of testing and counseling services. The objective of this study was to evaluate the integrated counseling and testing centers (ICTC) in New Delhi. MATERIALS AND METHODS: The evaluation study was conducted among ICTCs during 2014-2015. Twenty ICTCs of New Delhi were selected on the basis of population proportion to the size of clients catered. The study tool was pretested structured tool for evaluating HIV voluntary counseling and testing (VCT). The evaluation tool consists of an assessment of components including the availability of infrastructure, laboratory services, referral services, and staff availability. Counseling sessions were also observed for assessing content and quality. Means and proportions were calculated. RESULTS: Twelve (60%) ICTCs had dedicated counseling rooms ensuring privacy for the clients. Waiting space was reported to be adequate in 16 (80%) ICTCs. Space within counseling room was observed to be adequate in 8 (40%) ICTCs. Counselors of both sexes were present in 12 (60%) ICTCs. Both external and internal quality assurance was observed in all ICTCs. Standard operating procedures were followed in 15 (75%) ICTCs. On observation of the counseling sessions, it was found that 67.4% of male counselors and 67.2% of female counselors addressed all the issues of content of counseling. CONCLUSION: ICTCs lack waiting area and adequate space in counseling room and required staff personnel. Records maintenance and laboratory quality control maintained by ICTCs were found to be adequate. The counseling rooms lack privacy that may compromise the confidentiality of clients. Few components of counseling need improvement.

A prospective community-based study of stroke in Kolkata, India.

BACKGROUND AND PURPOSE: Information on essential stroke parameters are lacking in India. This population-based study on stroke disorder was undertaken in the city of Kolkata, India, to determine the subtypes, prevalence, incidence, and case fatality rates of stroke. METHODS: This was a longitudinal descriptive study comprising 2-stage door-to-door survey of a stratified randomly selected sample of the city population, conducted twice per year for 2 successive years from March 2003 to February 2005. RESULTS: Out of the screened population of 52,377 (27 626 men, 24 751 women), the age standardized prevalence rate of stroke to world standard population is 545.10 (95% CI, 479.86 to 617.05) per 100,000 persons. The age standardized average annual incidence rate to world standard population of first-ever-in-a-lifetime stroke is 145.30 (95% CI, 120.39 to 174.74) per 100,000 persons per year. Thirty-day case fatality rate is 41.08% (95% CI, 30.66 to 53.80). Women have higher incidence and case fatality rates. Despite divergence on socioeconomic status between the slum and nonslum dwellers, stroke parameters were not significantly different. CONCLUSIONS: The age standardized prevalence and incidence rates of stroke in this study are similar to or higher than many Western nations. The overall case fatality rate is among the highest category of stroke fatality in the world. The women have higher incidence and case fatality rates compared with men.

Psychosocial Determinants of Tobacco Use among School Going Adolescents in Delhi, India.

Background. Tobacco use is one of the major preventable causes of premature death and disease in the world. Many psychosocial factors were found to influence tobacco use. Therefore the present study was designed to determine the role of psychosocial factors associated with tobacco use among school going adolescents in Delhi, India. Methods. Cross-sectional study was conducted from February 2013 to September 2013 in four government schools in South district of Delhi, India. The questionnaire contains questions adapted from GYTS (Global Youth Tobacco Survey) to find the prevalence and pattern of tobacco use among adolescents. Data were analyzed using SPSS version 21. Results. The prevalence of ever and current tobacco use was found in 16.4% and 13.1%. Current smoking and current tobacco chewing were found in 10.2% and 9.4% students, respectively. The risk of current tobacco use was found to be higher among males (P value = 0.000) and in those who got higher pocket money (P value = 0.000). Psychosocial factors like lower general self-efficacy and maladjustments with peers, teachers, and schools were also found to be significant predictors of current tobacco use. Conclusion. The study has revealed higher prevalence of ever and current tobacco use among adolescent students in Delhi, India.

Systemic random sampling method was used to select 863 mothers/caregivers attending the immunization clinic. Results. At the immunization clinic, the study participants spent 64.1% of their total time in waiting. For new cases, the mean time taken for initial registration and receiving postvaccination advice was found to be significantly longer than old cases. Delivering health care services took more time during Mondays and also during the first hour of the day. Conclusion. Results of this study will guide public health decision-makers at all government levels in planning and implementation of immunization programs in developing countries.

Forecasting malaria cases using climatic factors in delhi, India: a time series analysis.

Background. Malaria still remains a public health problem in developing countries and changing environmental and climatic factors pose the biggest challenge in fighting against the scourge of malaria. Therefore, the study was designed to forecast malaria cases using climatic factors as predictors in Delhi, India. Methods. The total number of monthly cases of malaria slide positives occurring from January 2006 to December 2013 was taken from the register maintained at the malaria clinic at Rural Health Training Centre (RHTC), Najafgarh, Delhi. Climatic data of monthly mean rainfall, relative humidity, and mean maximum temperature were taken from Regional Meteorological Centre, Delhi. Expert modeler of SPSS ver. 21 was used for analyzing the time series data. Results. Autoregressive integrated moving average, ARIMA (0,1,1) (0,1,0)(12), was the best fit model and it could explain 72.5% variability in the time series data. Rainfall (P value = 0.004) and relative humidity (P value = 0.001) were found to be significant predictors for malaria transmission in the study area. Seasonal adjusted factor (SAF) for malaria cases shows peak during the months of August and September. Conclusion. ARIMA models of time series analysis is a simple and reliable tool for producing reliable forecasts for malaria in Delhi, India.

Clinico-pathological features of gynecological malignancies in a tertiary care hospital in eastern India: importance of strengthening primary health care in prevention and early detection.

BACKGROUND: This cross-sectional observational study was undertaken to establish clinico-pathological characteristics of patients with gynecological malignancies, focusing mainly on symptoms, histological type and stage of the disease at presentation, in a tertiary care setting in Eastern India. MATERIALS AND METHODS: In the gynecology out-patient clinic of a tertiary care hospital in Kolkata, India, the patients with suggestive symptoms of gynecological malignancies were screened. Their diagnoses were confirmed by histopathology. One hundred thirteen patients with histopathologically confirmed gynecological malignancies were interviewed. RESULTS: The most frequently reported symptoms by the patients with histopathologically confirmed gynecological malignancies were excessive, offensive with or without blood stained vaginal discharge (69.0%), irregular, heavy or prolonged vaginal bleeding (36.3%) and postmenopausal bleeding (31.9%). The majority of the patients (61.0%) had squamous cell carcinoma on histopathological examination, followed by adenocarcinoma (30.1%). Nearly half of the patients (48.7%) were suffering from the Federation Internationale des Gynaecologistes et Obstetristes (FIGO) stage III, followed by stage II (40.7%) malignancy. CONCLUSIONS: This study highlights that most of the patients with gynecological malignancies present late at an appropriate health care facility. Ovarian cancer may often have non-specific or misleading symptomatic presentation, whereas cervical cancer often presents with some specific symptoms. These observations point to the need for increasing awareness about gynecological malignancies in the community and providing easily accessible adequate facilities for early detection and treatment of the disease by optimal use of available resources, i.e. strengthening the primary health care system.

The unusual presentation of a usual organism - the changing spectrum of the clinical manifestations of Plasmodium vivax malaria in children: a retrospective study.

BACKGROUND: Malaria is a major public health problem in the south-east Asian region. Among all countries in the SE Asian region the highest number of cases and deaths are reported from India. Children below 14 years of age contribute to approximately 42% of all the deaths. A majority of the deaths are attributed to severe malaria which is caused by Plasmodium falciparum. It is considered that causes a benign causing febrile illness without significant complications. However, in recent years, the spectrum of is shifting from being the cause of benign fever, to more severe complications. There have been case reports of complications like thrombocytopaenia, cerebral malaria, a disseminated intravascular coagulation, the acute respiratory distress syndrome, hepatic dysfunction and renal involvement. Most of the case reports are from the adult population, with an occasional occurrence of paediatric cases. OBJECTIVE: To highlight the increasing number of severe manifestations in P.vivax malaria in the children who were admitted in the malaria transmission season of 2011, at a tertiary care hospital. DESIGN: A descriptive, cross-sectional study. STUDY SUBJECTS: Children with an acute febrile illness of a duration of < 7 days, which was confirmed as Plasmodium vivax positive malaria by testing the peripheral smears and/or by Rapid Diagnostic Testing, who were admitted in the paediatric ward of a tertiary care hospital in New Delhi (India), during May 2011 to October 2011, Case records of context cases were analysed retrospectively. STATISTICS: The data was summarised by calculating the rates, ratios, proportions, means, standard deviations and the 95% confidence intervals. The Chi square test was applied to assess the significant difference between two qualitative variables. RESULTS: Among the case records of 54 patients, 40.7% were below 5 years. 61% were males and 38.9% were females. Besides hepatomegaly and splenomegaly which were the most common symptoms, which were seen in 81.5% and 72.2% children respectively, the various unusual manifestations seen were severe thrombocytopaenia (37%), jaundice with deranged LFT values (25.9%), abnormal bleeding (18.5%), impaired consciousness with a GCS of < 9 (18.5%), severe anaemia (14.8%), hypotension (11.1%), repeated convulsions (7.6%), pulmonary oedema/ARDS (5.6%) and ascites (5.6%). One case each showed haemoglobinuria, and pleural effusion. CONCLUSION: Plasmodium vivax is emerging as a cause of severe malaria. There is a further need to study the pathophysiology, virulence factors and the molecular mechanisms which are involved in malaria.

Community survey of primary dystonia in the city of Kolkata, India.

An epidemiological study on dystonia has not been reported from India. As part of a major study to find out the prevalence of major neurological disorders in the large urban city of Kolkata, Eastern India, we planned to determine the prevalence of primary dystonia. The study design was a cross-sectional study of a sample population obtained through stratified random selection and conducted in a two-stage procedure of screening by a nonprofessional team followed by confirmation of screened positive cases by the study neurologist. A total population of 52,377 was screened, and 29 subjects with dystonia were diagnosed. Out of them 23 subjects had primary dystonias [crude prevalence rate (CPR), 43.91/100,000; 95% confidence interval (CI), 28.41-64.81; age-standardized rates to world standard population, 49.06 (95% CI,31.74-72.41)] and all cases were focal type and predominantly of limb dystonia variety. Mean onset of dystonias were earlier in women (43.5 years) as compared to men (46.6 years). Thus our study on primary dystonia shows higher prevalence when compared with that of many studies globally, predominantly of focal type, earlier onset among women, and more cases of limb dystonias when compared with more prominent blepharospasm and cervical dystonias in western reports.

Epidemiological study of neurological disorders in a rural population of Eastern India.

The study was conducted to determine the prevalence of neurological diseases in a rural community in Eastern India through a community based survey with the help of trained doctors following on WHO protocol (1981) translated in local vernacular, among 20842 rural residents (male-11037, female-9805, census India-1991, the State of West Bengal in Eastern India) over a period of one yearfrom May 1992 to April 1993 in two phases. Professionals screened the patients by house to house survey in the first phase and later on they were examined in details in temporary clinics in second phase. A total of 606 patients were identified and classified according to well-defined diagnostic criteria. The commonest diseases per 100,000 were headache: 870, vertebral diseases with neurological involvement: 540, seizure disorders: 360, vertigo: 230, stroke: 147, movement disorders: 140, peripheral neuropathy: 80. The age and sex specific prevalence showed increasing frequency of neurological disorders with advancing age in both genders excepting slight dip in the fourth and fifth decades among females. In the present study prevalence of headache, epilepsy, stroke and Parkinson's disease was lower than that of in the Western countries. Different inclusion criteria, multiethnicity, different environmental factors, poor medical facility and insufficient number of aged population may be responsible for lower prevalence of chronic neurological disorders as compared to Western countries. Increase in the life expectancy in future will lead to increasing burden of chronic neurological diseases in absolute term in Indian society considering the one billion population at present.
