Prevalence of pulmonary hypertension among children with Down syndrome: A systematic review and meta-analysis.

BACKGROUND: Pulmonary hypertension (PH) has serious short- and long-term consequences. PH is gaining increasing importance in high risk groups such as Down syndrome (DS) as it influences their overall survival and prognosis. Hence, there is a dire need to collate the prevalence rates of PH in order to undertake definitive measures for early diagnosis and management. AIM: To determine the prevalence of PH in children with DS. METHODS: The authors individually conducted a search of electronic databases manually (Cochrane library, PubMed, EMBASE, Scopus, Web of Science). Data extraction and quality control were independently performed by two reviewers and a third reviewer resolved any conflicts of opinion. The words used in the literature search were "pulmonary hypertension" and "pulmonary arterial hypertension"; "Down syndrome" and "trisomy 21" and "prevalence". The data were analyzed by Comprehensive Meta-Analysis Software Version 2. Risk of bias assessment and STROBE checklist were used for quality assessment. RESULTS: Of 1578 articles identified, 17 were selected for final analysis. The pooled prevalence of PH in these studies was 25.5%. Subgroup analysis was carried out for age, gender, region, year of publication, risk of bias and etiology of PH. CONCLUSION: This review highlights the increasing prevalence of PH in children with DS. It is crucial for pediatricians to be aware of this morbid disease and channel their efforts towards earlier diagnosis and successful management. Community-based studies with a larger sample size of children with DS should be carried out to better characterize the epidemiology and underlying etiology of PH in DS.

Variation in pulmonary function tests among children with sickle cell anemia: a systematic review and meta-analysis.

INTRODUCTION: the spectrum of pulmonary complications in sickle cell anemia (SCA) comprises mainly of acute chest syndrome (ACS), pulmonary hypertension (PH) and airway hyper-responsiveness (AHR). This study was conducted to examine the abnormalities in pulmonary function tests (PFTs) seen in children with SCA. METHODS: electronic databases (Cochrane library, PubMed, EMBASE, Scopus, Web of Science) were used as data sources. Two authors independently reviewed studies. All case-control studies with PFT performed in patients with SCA and normal controls were reviewed. Pulmonary functions were assessed with the help of spirometry, lung volume and gas diffusion findings. RESULTS: nine studies with 788 SCA children and 1101 controls were analyzed. For all studies, the pooled mean difference for forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), FEV1/FVC ratio, peak expiratory flow rate (PEFR), total lung capacity (TLC) and carbon mono-oxide diffusing capacity (DLCO) were -12.67, (95% CI: -15.41,-9.94), -11.69, (95% CI: -14.24, -9.14), -1.90, (95% CI: -4.32, 0.52), -3.36 (95% CI: -6.69, -0.02), -7.35, (95% CI: -14.97, -0.27) and -4.68, (95% CI -20.64, -11.29) respectively. FEV1 and FVC and were the only parameters found to be significantly decreased. CONCLUSION: sickle cell anemia was associated with lower FEV1 and FVC, thus, supporting the role of routine monitoring for the progression of lung function decline in children with SCA with ACS. We recommend routine screening and lung function monitoring for early recognition of pulmonary function decline.

Red reflex test screening for neonates: A systematic review and meta analysis.

Red reflex test (RRT) screening is yet to be a part of the neonate's normal examination before discharge from hospital in a majority of low- and middle-income countries. The purpose was this review was to systematically evaluate the diagnostic accuracy of RRT for the detection of ocular abnormalities in newborns. PubMed, EMBASE, Scopus, Web of Science, and Cochrane database of systematic reviews were the data sources. Quality of Diagnostic Accuracy Studies-2 (QUADAS-2) was utilized for quality assessment of bias and applicability. Random effects models were used to summarize sensitivities, specificities, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and respective confidence intervals (CI). The pooled sensitivity, calculated from the meta analysis of 11 studies, was 23% (95% CI: 21-24%) and pooled specificity was 98% (95% CI: 98-98%). The PLR was 32.52 (95% CI: 7.89-134.15), NLR was less than 1 (0.69 [95% CI: 0.55-0.88]), and DOR calculated was 138.48 (95% CI: 23.85-803.97). The area under the curve (AUC) and Q* index for RRT were 0.98 ± 0.02 and 0.95 ± 0.045, respectively. The results of our study justify the conclusion that RRT is a highly sensitive and specific test for the detection of anterior segment abnormalities.

Epidemiology of confirmed coronary heart disease among population older than 60 years in rural central India-A community-based cross-sectional study.

BACKGROUND: Three-fifths of total deaths in India are attributed to noncommunicable diseases, and coronary heart disease (CHD) is one of the dominant causes. There are only few studies available in India to find confirmed CHD by pragmatic approach. This study aims to find prevalence of confirmed CHD and its risk factors in rural community of central India. MATERIALS AND METHODS: This was a community-based cross-sectional study during 2013-2014 involving adults ≥60 years from 13 villages in rural central India. We screened CHD on the basis of history and standard 12-lead ECG. Apart from the past documentation of CHD, we diagnosed confirmed CHD in symptomatic patients or with resting ECG changes by means of echocardiography, exercise ECG test or coronary angiography whenever needed. RESULTS: We screened 1190 of 1415 individuals ≥60 years for CHD. Five hundred eighty were men and 610 were women. Diagnosis of CHD was confirmed in 61 individuals (29 men and 32 women). The prevalence of CHD in individuals older than 60 years was 51.3 per 1000 population. Hypertension was the only independent risk factor associated with CHD, whereas association of diabetes mellitus, obesity, socioeconomic status and smoking with CHD was not significant. CONCLUSION: Prevalence of confirmed CHD has increased in agrarian rural community in central India, which requires further studies to find out causative factors.

Knowledge, attitude, and practice of foot care in patients with diabetes at central rural India.

INTRODUCTION: Diabetic foot syndrome is one of the common and most devastating preventable complications of diabetes mellitus (DM). It is associated with morbidity and premature mortality due to long-term complications affecting foot. The American Diabetes Association recommends that people with diabetes should have a comprehensive foot examination once per year. Most of the foot problems can be prevented with careful foot care. It may take effort and time to build up good foot care habits, but self-care is essential. AIM: The main aim of the study is to analyze the knowledge, attitude, and practice of foot care in patients with DM in central rural India. METHODOLOGY: This study was conducted at a rural educational hospital in central part of India over 200 patients who have Type 1 and Type 2 diabetes. They were evaluated for their knowledge about foot care and footwear practices. A structured and validated questionnaire was administered to cases. RESULTS: Around 82.9% of the patients were aware of the disease and 23.2% were aware of the complications of the DM. In 63% of the patients, foot care examination and education regarding foot complications were not suggested by their treating physicians. Annual examination of feet by the physician and self-examination were not known facts to the diabetic population. CONCLUSION: It is necessary to firstly develop awareness of diabetes mellitus and the related complications, one amongst which is foot care. Certain educational strategies should be established for both the consultant physician and also the common man to create awareness for effective foot care.

Ventricular bigeminy in acute organophorous poisoning - A rare ECG finding.

India being a land of farmer, the pesticides are freely and easily available and therefore organophosphorous poisoning is one of the major health issues. Suicidal poisoning is more common than accidental poisoning. Cardiac manifestations of organophosphorous poisoning are well known. It results in various electrocardiographic changes from sinus tachycardia to ST elevation. We hereby present a rare ECG finding of ventricular bigeminy in a case of acute organophosphorous poisoning.

Unusual presentation of orbital cysticercosis-ptosis, diminution of vision and medial rectus weakness: a case report.

Cysticercosis is the most common parasitic disease of the nervous system. The disease occurs when humans become the intermediate host in the life cycle of Taenia solium by ingesting its eggs from contaminated food. The most common sites of involvement of cysticerci are soft tissue, eye and central nervous system. Unusual location of the cysts may result in uncommon manifestations. Ocular cysticercosis can involve both the intraocular and extra ocular muscle. Extra ocular muscle cysticercosis is rare. We are reporting the unusual manifestation of ptosis, proptosis, diminution of vision and medial rectus palsy due to cysticercosis. The patient was successfully treated with systemic steroids and albendazole.

Profile of adults seeking voluntary HIV testing and counseling in rural Central India: results from a hospital-based study.

Rural India has an undetected load of HIV-positive individuals. Few rural adults present for HIV testing and counseling due to stigma, discrimination, and fear of social ostracization. In this rural hospital clinic-based study, we document profiles of rural adults seeking voluntary testing and counseling, and analyze correlates of HIV seropositivity. This cross-sectional study was conducted in 450 participants presenting to the outpatient clinics of Mahatma Gandhi Institute of Medical Sciences, Sevagram, Central India. After informed consent, pre- and post-test counseling, HIV testing, and face-to-face interviews were conducted. Data were collected using a structured questionnaire. The median age of the 450 study participants was 34 years (range 18-88 years); the majority (74%) was married. The overall proportion of HIV seropositivity was 32% [95% CI 28%, 37%]. The proportions of HIV seropositivity in married women, married men, and single men were 41%, 37%, 18%, respectively. No single woman was found seropositive in the study. Very few married women were aware of their husbands' HIV status. In a multivariate analysis, correlates of HIV seropositivity in men were: age 30-39 years, being married, having sex with multiple partners, use of alcohol before sex, and testing positive for HIV in the past. In married women, the only predictor of seropositivity was being married. Although limited by the non-random nature of the sampling method, this pilot study is unique in that it is the first from this rural region of Central India. It provides baseline data on marginalized, largely unstudied populations that may aid in designing probabilistic community-based surveys in this neglected population.

Evaluation of diagnostic accuracy, feasibility and client preference for rapid oral fluid-based diagnosis of HIV infection in rural India.

BACKGROUND: Oral fluid-based rapid tests are promising for improving HIV diagnosis and screening. However, recent reports from the United States of false-positive results with the oral OraQuick ADVANCE HIV1/2 test have raised concerns about their performance in routine practice. We report a field evaluation of the diagnostic accuracy, client preference, and feasibility for the oral fluid-based OraQuick Rapid HIV1/2 test in a rural hospital in India. METHODOLOGY/PRINCIPAL FINDINGS: A cross-sectional, hospital-based study was conducted in 450 consenting participants with suspected HIV infection in rural India. The objectives were to evaluate performance, client preference and feasibility of the OraQuick Rapid HIV-1/2 tests. Two Oraquick Rapid HIV1/2 tests (oral fluid and finger stick) were administered in parallel with confirmatory ELISA/Western Blot (reference standard). Pre- and post-test counseling and face to face interviews were conducted to determine client preference. Of the 450 participants, 146 were deemed to be HIV sero-positive using the reference standard (seropositivity rate of 32% (95% confidence interval [CI] 28%, 37%)). The OraQuick test on oral fluid specimens had better performance with a sensitivity of 100% (95% CI 98, 100) and a specificity of 100% (95% CI 99, 100), as compared to the OraQuick test on finger stick specimens with a sensitivity of 100% (95% CI 98, 100), and a specificity of 99.7% (95% CI 98.4, 99.9). The OraQuick oral fluid-based test was preferred by 87% of the participants for first time testing and 60% of the participants for repeat testing. CONCLUSION/SIGNIFICANCE: In a rural Indian hospital setting, the OraQuick Rapid- HIV1/2 test was found to be highly accurate. The oral fluid-based test performed marginally better than the finger stick test. The oral OraQuick test was highly preferred by participants. In the context of global efforts to scale-up HIV testing, our data suggest that oral fluid-based rapid HIV testing may work well in rural, resource-limited settings.
