School environment on social development of students with hearing impairment in Bassa, Plateau state, Nigeria

Introduction: School environment is a learning place where the learners learn and interact with learning facilities in order to be socialized and face the challenges in the society. Purpose: This study was carried out to evaluate on impact of school environment on social development of children with hearing impairment in School for the Deaf, Bassa, Plateau State. Methodology: The study was carried out with the use of questionnaires from fifty respondents as a method of data collection. The sample drawn from the Population for the study consists of students from students in School for the Deaf, Bassa, Plateau State. The data collected through this medium were analyzed using simple percentage and discussed with explanations. Results: The study find out Children’s social behaviors depend on several factors both human and physical environment. Classroom teachers and parents contribute immensely to the children’s social behaviors, limited access to both the students and teachers to reading materials, quality of school building and unavailability of good library has great influence on student social development. Recommendations: It is recommended that adequate classroom building, well-equipped library and other schools facilities should be provided in the school to help promote students social development

Human pulmonary infections with bovine and environment (atypical) Mycobacteria in Jos, Nigeria

Objectives: To examine sputum specimens frompatients with persistent bronchopulmonary disorders for mycobacterium species and to characterize the recovered isolates with a view to determiningthe extent of involvement of environmental mycobacteria in pulmonary infections. Design: Analytical study using standard microscopy,culture and biochemical test for the identification of mycobacterium species. Setting: Jos University Teaching Hospital (JUTH)and 2 referral hospitals: Plateau Specialist Hospital and Evangelical Churches of West Africa (ECWA) Evangel Hospital in Jos, Nigeria.Participants: Three hundred and twenty nine (329) volunteer new patients seen at the chest clinic and general out patient departments with broncho-pulmonary disorders. Patients already on anti-tuberculosis were excluded from the study. Interventions: Subjects were administered antituberculosis drugs and or other treatment regimes after proper diagnosis Results: Sixty-five (65) mycobacterial isolates were obtained and differentiated into human tuberclebacilli, bovine and or environmental (atypical) mycobacteria on the basis of nine identification tests. Of the 65 mycobacterial isolates subjected to the tests, 40 (61.54%) were identified as mycobacteriumtuberculosis, 10 (15.38%) as M. bovis and 15 (23.08%) as environmental mycobacteria. Among the environmental group, 9 (20.69%) were classified as M. avium 3 (3.45%) each as M. kansasiand M. fortuitum. Conclusions: The study confirms the involvementof bovine and environmental mycobacteria in pulmonary infections. This may be related to the rising prevalence of HIV/AIDS globally. The need for adequate bacteriological analysis in current-day diagnosis of pulmonary tuberculosis in indicated

Burden of disease and circulating serotypes of rotavirus infection in sub-Saharan Africa: systematic review and meta-analysis.

Two new rotavirus vaccines have recently been licensed in many countries. However, their efficacy has only been shown against certain serotypes commonly circulating in Europe, North America, and Latin America, but thought to be globally important. To assess the potential impact of these vaccines in sub-Saharan Africa, where rotavirus mortality is high, knowledge of prevalent types is essential because an effective rotavirus vaccine is needed to protect against prevailing serotypes in the community. We did two systematic reviews and two meta-analyses of the most recent published data on the burden of rotavirus disease in children aged under 5 years and rotavirus serotypes circulating in countries in sub-Saharan Africa. Eligible studies were selected from PubMed/Medline, Cochrane Library, EmBase, LILACS, Academic Search Premier, Biological Abstracts, ISI Web of Science, and the African Index Medicus. Depending on the heterogeneity, DerSimonian-Laird random-effects or fixed-effects models were used for meta-analyses. Geographical variability in rotavirus burden within countries in sub-Saharan Africa is substantial, and most countries lack information on rotavirus epidemiology. We estimated that annual mortality for this region was 243.3 (95% CI 187.6-301.7) deaths per 100,000 under 5 years (ie, a total of 300,000 children die of rotavirus infection in this region each year). The most common G type detected was G1 (34.9%), followed by G2 (9.1%), and G3 (8.6%). The most common P types detected were P[8] (35.5%) and P[6] (27.5%). Accurate information should be collected from surveillance based on standardised methods in these countries to obtain comparable data on the burden of disease and the circulating strains to assess the potential impact of vaccine introduction

Hepatitis C Virus Antibodies Among Blood Donors in Jos, Nigeria

Background: Hepatitis C virus (HCV) is one of the hepatitis agents known to be transmitted through blood and blood products. Hepatitis C virus has been implicated as a major cause of chronic liver disease and hepatocellular carcinoma worldwide. This study was, therefore, undertaken with the objective of determining the sero-prevalence of HCV antibodies among blood donors in the central city of Jos, Nigeria. Method: A total of two hundred blood donors were recruited from three hospitals within Jos metropolis. Sera from all subjects were tested for Hepatitis C virus antibodies using a second generation enzyme linked immunosorbent assay (ELISA). Results: Ninety five percent (95%)of the blood donors were males and most of them were aged between 21 and 50years. Twelve (6.0%)of the blood donors were anti-HCV seropositive and all of them males. Conclusion: There is an urgent need to introduce routine screening of blood donors for Hepatitis C virus markers in centers where this is not currently been practiced. This will reduce the risk of transfusion-associated hepatitis C infection and its complications in Nigeria

Incidence of rotavirus infection in children with gastroenteritis attending Jos university teaching hospital, Nigeria

This study was conducted to determine the incidence of rotavirus infection in children with gastroenteritis attending Jos university teaching hospital, Plateau State. A total of 160 children with acute diarrhea were selected by random sampling. Stool samples were obtained and assayed for rotavirus antigens by enzyme linked immunosorbent assay technique using standard diagnostic BIOLINE Rotavirus kit. Demographic data of parents were also recorded. Rotavirus were detected in faeces of 22(13.8%) children with acute diarrhea, 90.9% of positive cases of rotavirus gastroenteritis were under 2 years of age with highest prevalence in children 7-12 months of age. Males excreted rotavirus at a significant higher rate than females (P < 0.05). Rotavirus excretion was highest when all three symptoms (diarrhea, fever and vomiting) occurred in the same child (7.5%) and lower when 2 symptoms occurred together (diarrhea and vomiting) with 3.8%, diarrhea and fever with 1.3% and lowest when diarrhea occurred alone with 1.3%. Playing with toys, attending day care, distance of source of water from toilet, eating of food not requiring cooking and playing with other children may serve as predisposing factors of rotavirus disease in these children

Sero-survey of rubella IgM antibodies among children in Jos, Nigeria

Sero-survey of rubella IgM antibodies was carried out among children aged 0-10 years in Jos, Nigeria. Blood samples were collected from the subjects and sera extracted. Of the 93(100%) assayed for the rubella IgM antibody, 42(45.2%) were seropositive for rubella IgM antibody while 51(54.8%) were seronegative. A breakdown of the seropositive subjects reveals that 14(15.1%) of the infected children were males while 28(30.1%) were females. Those subjects within the age groups of 1-2, 3-4 and 5-6 years had the highest prevalence of 8(8.6%) followed by those within the age groups of 7-8, 9-10 years with 7(7.5%). Blood transfusion as a risk factor did not show any significant influence on the status of the subjects. The demographic data of the mothers of the subjects were also linked with the seropositivity of the children

Estimating the burden of rubella virus infection and congenital rubella syndrome through a rubella immunity assessment among pregnant women in the Democratic Republic of the Congo: Potential impact on vaccination policy.

BACKGROUND: Rubella-containing vaccines (RCV) are not yet part of the Democratic Republic of the Congo's (DRC) vaccination program; however RCV introduction is planned before 2020. Because documentation of DRC's historical burden of rubella virus infection and congenital rubella syndrome (CRS) has been minimal, estimates of the burden of rubella virus infection and of CRS would help inform the country's strategy for RCV introduction. METHODS: A rubella antibody seroprevalence assessment was conducted using serum collected during 2008-2009 from 1605 pregnant women aged 15-46years attending 7 antenatal care sites in 3 of DRC's provinces. Estimates of age- and site-specific rubella antibody seroprevalence, population, and fertility rates were used in catalytic models to estimate the incidence of CRS per 100,000 live births and the number of CRS cases born in 2013 in DRC. RESULTS: Overall 84% (95% CI 82, 86) of the women tested were estimated to be rubella antibody seropositive. The association between age and estimated antibody seroprevalence, adjusting for study site, was not significant (p=0.10). Differences in overall estimated seroprevalence by study site were observed indicating variation by geographical area (p⩽0.03 for all). Estimated seroprevalence was similar for women declaring residence in urban (84%) versus rural (83%) settings (p=0.67). In 2013 for DRC nationally, the estimated incidence of CRS was 69/100,000 live births (95% CI 0, 186), corresponding to 2886 infants (95% CI 342, 6395) born with CRS. CONCLUSIONS: In the 3 provinces, rubella virus transmission is endemic, and most viral exposure and seroconversion occurs before age 15years. However, approximately 10-20% of the women were susceptible to rubella virus infection and thus at risk for having an infant with CRS. This analysis can guide plans for introduction of RCV in DRC. Per World Health Organization recommendations, introduction of RCV should be accompanied by a campaign targeting all children 9months to 14years of age as well as vaccination of women of child bearing age through routine services

The effect of listening comprehension skills on students' performance in oral English language test

This paper presents the report of a study that investigated the effects of listening comprehension skill training on students' performance in Oral English Test. To investigate the effects that the teaching of listening comprehension skills would have on the performance in Oral English test, 82 Senior Secondary School 2 students were selected from a Senior Secondary School in Bokkos town in Plateau State, Nigeria. On the whole, the finding shows that instruction in listening comprehension skills has a significant effect on the students' performance in an Oral English test. It thus means that students' performance in Oral English can be enhanced when they are taught listening comprehension skills and given variety of opportunities to practice and use the skills in oral communication.
