BackgroundSoil-transmitted helminth (STH) infections often affect the poorest and most deprived communities. In order to generate reliable data for planning a school based deworming program, we conducted a survey among primary school children studying in government schools in the Indian state of Uttar Pradesh. The objectives of our survey were to estimate the prevalence and intensity of STH infections.MethodsWe conducted a cross-sectional survey among children studying in 130 primary schools from 9 agro-climatic zones, during May – August 2015. Information about socio-demographic details, defecation and hand-hygiene practices, and stool samples were collected from the school children. Stool samples were examined using the Kato-Katz method.ResultsStool samples from 6421 school children were examined. The overall weighted prevalence of any STH in the State was 75.6% (95% CI: 71.2–79.5). The prevalence was more than 50% in six of the nine agro-climatic zones. A. lumbricoides was the most prevalent STH (prevalence: 69.6%), followed by hookworm (prevalence: 22.6%) and T. trichura (4.6%). The majority of the STH infections were of low intensity. The practice of open defecation and not washing hands with soap after defecation and residence in kutcha house were significant risk factors of STH infection.ConclusionsSTH prevalence among primary school children in Uttar Pradesh was high. Given the WHO guidelines on deworming frequency according to STH prevalence, Govt of Uttar Pradesh needs to implement a school-based deworming program with bi-annual frequency. The findings of our survey would also help monitor the performance of school based deworming programme.Electronic supplementary materialThe online version of this article (10.1186/s40249-017-0354-7) contains supplementary material, which is available to authorized users.

Soil-transmitted helminth (STH) infections are highly prevalent in many developing countries, affecting the poorest and most deprived communities. We conducted school-based surveys among children studying in first to fifth standard in government schools in the Indian States of Chhattisgarh, Telangana, and Tripura to estimate the prevalence and intensity of STH infections during November 2015 and January 2016. We adopted a two-stage cluster sampling design, with a random selection of districts within each agro-climatic zone in the first stage. In the second stage, government primary schools were selected by probability proportional to size method from the selected districts. We collected information about demographic details, water, sanitation, and hygiene (WASH) characteristics and stool samples from the school children. Stool samples were tested using Kato-Katz method. Stool samples from 3,313 school children (Chhattisgarh: 1,442, Telangana: 1,443, and Tripura: 428) were examined. The overall prevalence of any STH infection was 80.2% (95% confidence interval [CI]: 73.3–85.7) in Chhattisgarh, 60.7% (95% CI: 53.8–67.2) in Telangana, and 59.8% (95% CI: 49.0–69.7) in Tripura. Ascaris lumbricoides was the most prevalent STH infection in all three states. Most of the STH infections were of light intensity. Our study findings indicate that STH infections were highly prevalent among the school children in Chhattisgarh, Telangana, and Tripura, indicating the need for strengthening STH control program in these states. The prevalence estimates from the survey would serve as a baseline for documenting the impact of the National Deworming Day programs in these states.

Background: Haglund's syndrome an important cause of posterior heel pain presents with a prominent bony contour, a retrocalcaneal bursitis or achillis tendinitis these can also occur in isolation hence for the diagnosis of etiology of Haglund's disease certain radiological parameters and soft tissue parameters have been created to evaluate the anatomical variations which will assist in its exact diagnosis. Study aims to distinguish between the bony and soft tissue causes of Haglund's disease radiologically. Methodology: After Institutional ethical committee clearance an observational cross-sectional study was conducted with subjects coming to radiology OPD for X-ray foot with complains of posterior heel pain fulfilling inclusion and exclusion criteria were examined for X-ray lateral view of foot. Parameters like calcaneal inclination angle (CIA), Fowler Philip angle (FPA), parallel pitch line (PPL), Steffenson & Evenson angle (SEA) measured, posterior/calcaneal spur and posterior calcaneal step were noted. The data obtained was analyzed for mean, Standard deviation, sensitivity % and false negative %. Result: Sensitivity of the parameters were analyzed to find CIA, SEA &PPL to be 63.3%, 55% and 55% sensitive respectively. CIA could be assigned most sensitive but regarding soft tissue parameters none were sensitive. Conclusion: CIA, SEA & PPL were found to be sensitive among bony parameters. But none of the soft tissue parameters were sensitive radiologically highlighting a need for its correlation with clinical symptom in peripheral health centers where MRI is not available. Sensitivity of bony and soft tissue parameters were analyzed to find CIA, SEA & PPL to be sensitive. CIA could be assigned most sensitive among bony parameter but with regards to soft tissue parameters none were sensitive.
