Abstract Background. Malaria remains a major public health concern in Democratic Republic of Congo (DRC), and school-age children are relatively neglected in malaria prevalence surveys and may constitute a significant reservoir of transmission. This study aimed to understand the burden of malaria infections in school-age children in Kinshasa/DRC.Methods. 634 (427 asymptomatic and 207 symptomatic) blood samples were collected from a cross-sectional survey of school-age children aged 6 to 14 years both without and with malaria symptoms. Nested-PCR was performed for malaria parasite species typing. Results. The overall prevalence of Plasmodium spp., Plasmodium falciparum, Plasmodium malariae and Plasmodium ovale was 62.3, 58.1, 19.9 and 10.8% among asymptomatic whereas it was 94.4, 93.2, 12.6 and 15.9% in symptomatic children, respectively. All Plasmodium species infections were significantly more prevalent in the rural area compared to the urban area in asymptomatic infections (p<0.001). Living in a rural as opposed to an urban area was associated with a five-fold greater risk of asymptomatic malaria parasite carriage (p<0.001). Amongst asymptomatic malaria parasite carriers, 43% of children in the rural area were co-infected with two or more species with P. falciparum + P. malariae the most common (24%) whereas in the urban setting, fewer children carried co-infections (16%) with P. falciparum + P. malariae again the most common (9%). A fifth of rural-dwelling symptomatic children were co-infected with two or more species with P. falciparum + P. ovale the most common (14%), while a quarter of symptomatic children in the urban area carried multiple species, with co-infections of P. falciparum + P. malariae the most common (11%). Conclusion. School-age children are at significant risk from both asymptomatic and symptomatic malaria parasite infections. Continuous systematic screening and treatment of school-age children in high-transmission settings across the country may reinforce malaria intervention measures.

Clinical low vision services are a vital related service for students with low vision. A rationale and a model are offered for the delivery of services through a regional Education Service Center in a sparsely populated area of Texas. Optical aids and vision stimulation programs were provided for students who could benefit from them.

Background: Highest intensity of soil transmitted helminthiasis (STH) is seen among school age children. The objective of this study is to find out the prevalence and factors associated with STH infection among school age children of 5-14 years in a rural area of Coimbatore district.Methods: After getting ethical clearance, five of the fourteen villages of Vedapatti were selected by cluster sampling method. Totally 819 participated in the survey conducted between November 2015-July 2016 in the field practice area. Consent from parents and assent from child were obtained. Structured questionnaire was used to collect information. Totally 610 gave one adequate stool sample. Early morning samples were collected and transported to the laboratory within four hours. Formal ether concentration method was performed and examination was done. Data analysis was done with SPSS-19 software. Prevalence is expressed in percentage with 95% confidence interval (CI). Univariate and Multivariate analysis were performed. Strength of association was expressed in terms of odds ratio and adjusted odds ratio with 95% confidence interval. P value <0.05 was considered as statistically significant.Results: The prevalence of STH was 7.70% (95% CI: 5.58- 9.82). Ascaris lumbricoides was highly prevalent 6.9% (4.89% to 8.91%) followed by hook worm 0.2(0.15% to 0.55%) and Trichuris trichura 0.7%(0.04% to 1.36%). Uni variate and Multivariate logistic regression analysis showed that pucca houses offered protection against STH.Conclusions: STH is still a public health problem in Coimbatore. When regular deworming is accompanied by appropriate sanitation and hygiene activities designed to prevent re infection of STH, a long-term impact can be achieved.

This study was designed to determine if a remedial program using a bite-block device could inhibit hypermandibular activity (HMA) and thereby improve the lingua-alveolar valving (LAV) abilities of four school-age children who demonstrated multiple lingua-alveolar (LA) phonemic errors. The results revealed significant improvements in LAV and LA phoneme articulatory skills in all of the children who used the bite-block device to reduce HMA subsequent to comprehensive training sessions.
