RESUMO
PURPOSE: Dental caries and poor oral hygiene cause pain and have an effect on activities of children such as playing, sleeping, eating and school attendance. Previous studies on the prevalence of dental caries and poor oral hygiene have focused more on urban than rural communities in the developing countries. The objective of the study was to assess dental caries and oral hygiene status of schoolchildren in rural communities. MATERIALS AND METHODS: It was a cross-sectional study involving 778 schoolchildren from 12 public primary schools. A pre-tested, semi-structured interviewer-administered questionnaire was used to obtain information on socio-demographics and oral health practice. Dental caries was assessed using the decayed, missing and filled teeth (DMFT) index and oral hygiene status by the simplified oral hygiene and gingival indices. RESULTS: The mean age of the children was 11.0 ± 1.8 years, and the prevalence of dental caries was 12.2% with a mean DMFT/dmft of 0.2 ± 0.7. Children aged 10-12 years were 3 times more likely to have caries on ≥1 tooth (P = 0.01, confidence interval = 1.3-6.7). Herbal remedies were more often (35.3%) used to manage dental problems. The mean simplified oral hygiene and gingival indices were 1.7 ± 0.9 and 1.1 ± 0.5, respectively. CONCLUSION: The occurrence of dental caries appears to be increasing in rural Nigerian schoolchildren, but still within WHO limits. Oral hygiene status was poor and gingivitis was common.

BACKGROUND: Malaria case management remains a vital component of malaria control strategies. Despite the introduction of national malaria treatment guidelines and scale-up of malaria control interventions in Nigeria, anecdotal evidence shows some deviations from the guidelines in malaria case management. This study assessed factors influencing adherence to malaria diagnosis and treatment guidelines among healthcare workers in public and private sectors in Ogun State, Nigeria. METHODS: A comparative cross-sectional study was carried out among 432 (216 public and 216 private) healthcare workers selected from nine Local Government Areas using a multistage sampling technique. A pre-tested interviewer administered questionnaire was used to collect information on availability and use of malaria Rapid Diagnostic Test (mRDT) and artemisinin combination therapy (ACT), for management of uncomplicated malaria. Adherence was defined as when choice of antimalarials for parasitological confirmed malaria cases was restricted to recommended antimalarial medicines. Association between adherence and independent variables were tested using Chi-square at 5 % level of significance. RESULTS: Malaria RDT was available in 81.9 % of the public health facilities and 19.4 % of the private health facilities (p = 0.001). Its use was higher among public healthcare workers (85.2 %) compared to 32.9 % in private facilities (p = 0.000). Presumptive diagnosis of malaria was higher among private healthcare workers (94.9 %) compared to 22.7 % public facilities (p = <0.0001). The main reason for non-usage of mRDT among private healthcare workers was its perceived unreliability of mRDT (40.9 %). Monotherapy including artesunate (58.3 % vs 12.5 %), amodiaquine (38.9 % vs 8.3 %) and chloroquine (26.4 % vs 4.2 %) were significantly more available in private than public health facilities, respectively. Adherence to guidelines was significantly higher among public healthcare workers (60.6 %) compared to those in private facilities (27.3 %). Availability of antimalarial medicine was the main factor that influenced treatment prescription in both healthcare settings (p = 0.27). However, drug promotion by manufactures (45.8 %) has a major influence on private healthcare workers' prescription practice. CONCLUSION: The findings of this study demonstrate significant difference between public and private healthcare workers on adherence to national malaria diagnosis and treatment guidelines. Interventions to improve private sector engagement in implementation of the guidelines, training and supply of recommended antimalarial medicines should be intensified.

Introduction: the response to COVID-19 pandemic has posed new obstacles to the fragile health system, most especially in the area of vaccination across much of Africa. As the response to the pandemic intensifies through the application of non-pharmacologic interventions as well as enforcement of the lockdowns across African cities, there is a significant risk that more children will miss out on life-saving vaccines that can prevent childhood killer diseases. This study was therefore conducted to look at the impact of the COVID-19 pandemic on routine immunization in Oyo State, Nigeria. Methods: we conducted a descriptive secondary analysis of immunization data between July 2019 and August 2020. These data were retrieved from the monitoring and evaluation unit of Oyo State Primary Health Care Board. The data were extracted from the original paper format and entered into Excel sheets. Line graphs were plotted to compare the trends of the coverage rates before and after the index case of the COVID-19 pandemic. Results: the average coverage rates for Bacillus Calmette-Guérin (BCG) before and after index case were 85.8% and 82.1% respectively, while it was 63.5% and 60.0% for HBV0. For the co-administered vaccines at 14 weeks, Penta 3, OPV 3, PCV 3 and IPV coverage rates dropped from 76.1%, 75.4%, 75.1% and 73.5% to 72.0%, 71.4%, 72.0% and 71.9% respectively. The average coverage rates for yellow fever and measles dropped sharply from 77.0% and 74.5% and 64.6% and 58.6% respectively. The average drop-out rates for the pre-and post-index case periods were 5.0% and 4.7% respectively. For the planned fixed and outreach sessions, none of the monthly sessions met the target of 100.0% in the post-index case period. Conclusion: decreased vaccination coverage for vaccine-preventable diseases could cause parallel outbreaks with COVID-19 and further exacerbate the strain on health systems attempting to end the acute phase of this pandemic. Therefore, as the dramatic second wave unfolds, the Government of Nigeria must take deliberate steps to strike a balance between a fresh lockdown and the imperative of uninterrupted social service. In this wise, it must remain committed to a timely vaccination program.

OBJECTIVES: This study aims to explore the utilization rate and factors influencing the use of HCT services among young females in Ikorodu, Lagos State, Nigeria. METHODS: This study was a descriptive cross-sectional survey of 404 females, aged 15-24 years, residing in Ikorodu, Nigeria. Study tool was a questionnaire. Collected data was analyzed using the SPSS version 16 software. RESULTS: The mean age (±SD) of the respondents was 19.3 (±2.6) years and 90.1% were single. Only 148 (36.6%) respondents had ever utilized the HCT service, of which only 40.5% of them were adolescents. Amongst those that had ever utilized HCT services (n=148), only 60.1% of them did so within 12 months prior to the study while only 33.8% of them initiated the demand for testing themselves. According to the respondents, the top two barriers to the utilization of HCT services were: fear of discrimination (82.9%); and fear of unavailability of access to treatment (68.0%), while the top two factors that facilitates its use were: the adoption of counseling-before-testing approach in the HCT service centers (85.9%); and peoples' need for HIV status declaration prior to getting a job employment/marriage partner (85.1%). CONCLUSIONS: The study shows that utilization of HCT service remains low among the respondents. There is an urgent need to encourage the utilization of HCT services among young females in Ikorodu, Nigeria.
RESUMO
INTRODUCTION: Typically hyperthyroidism has been more often associated with the female gender. There is a large female predilection (male:female sex ratio up to 1:10), with little documentation in the literature about wholly male hyperthyroid populations. A male incidence of 0.7 per 100, 000 has been reported for South African men while the women have a relatively higher rate of 0.02. There is no documented evidence between male and female genders in response to treatment of PH with radioactive iodine (RAI), although operational evidence suggests that hyperthyroidism in males is less amenable to RAI treatment (RAIT) than females. This study therefore proposed to evaluate male hyperthyroid patients with Graves' disease (GD) treated at our facility, for factors affecting outcome of RAIT. METHODS: This is a retrospective analysis of records of hyperthyroid patients who were treated with RAI over a 19-year period at a university teaching hospital, in the Western Cape of South Africa. RESULTS: The overall cure rate was 76.4% for these male patients. Cure was observed as euthyroidism in 31 patients (15.3%) and hypothyroidism in 129 (63.5%). Age, thyroid uptake, severity of hyperthyroidism, previous antithyroid drug (ATD) usage, administered quantity of RAI, ethnicity and patients' pulse at presentation were not significant in influencing outcome. CONCLUSION: Factors which have been evaluated as affecting outcome of RAIT were unimportant in these patients. Despite the mainly hyperthyroid presentation of the patients, RAIT was so effective that the main type of cure after therapy was hypothyroidism.

BACKGROUND: Improper handling has been identified as one of the major reasons for the decline in vaccine potency at the time of administration. Loss of potency becomes evident when immunised individuals contract the diseases the vaccines were meant to prevent. OBJECTIVE: Assessing the factors associated with vaccine handling and storage practices. METHODS: This was a cross-sectional study. Three-stage sampling was used to recruit 380 vaccine handlers from 273 health facilities from 11 Local Government areas in Ibadan. Data was analysed using SPSS version 16. RESULTS: Seventy-three percent were aware of vaccine handling and storage guidelines with 68.4% having ever read such guidelines. Only 15.3% read a guideline less than 1 month prior to the study. About 65.0% had received training on vaccine management. Incorrect handling practices reported included storing injections with vaccines (13.7%) and maintaining vaccine temperature using ice blocks (7.6%). About 43.0% had good knowledge of vaccine management, while 66.1% had good vaccine management practices. Respondents who had good knowledge of vaccine handling and storage [OR=10.0, 95%CI (5.28 - 18.94), p < 0.001] and had received formal training on vaccine management [OR=5.3, 95%CI (2.50 - 11.14), p< 0.001] were more likely to have good vaccine handling and storage practices. CONCLUSION: Regular training is recommended to enhance vaccine handling and storage practices.

INTRODUCTION: Nigeria has the thirteenth highest burden of human tuberculosis. The current increasing incidence of tuberculosis in humans, particularly in immune-compromised persons, has given interest in the zoonotic importance of Mycobacterium bovis in developing countries like Nigeria. This study determined the prevalence of bovine tuberculosis as a background information for effective control measures in Plateau State in cattle population. METHODS: We reviewed surveillance records on cattle slaughtered and suggestive tuberculosis lesions from cattle slaughtered annually from 2007-2012 in Jos abattoir, Plateau State. Bovine tuberculosis cases at post mortem were based on examination of characteristics TB lesion on organs by Veterinary officers. We performed descriptive analysis using Epi info version 3.5.3 and Microsoft Excel 2007. RESULTS: A total of 52, 262 cattle were slaughtered from 2007-2012, out of which 4, 658 (11.2%) had evidence of tuberculosis lesion at post mortem. The average yearly prevalence was 9.1% but varied from a high of 16.3% in 2007 to a low of 3.1% in 2012. Trend analysis showed that bovine tuberculosis had a seasonal variation and peaked mostly in July and August. The number of suggestive Tb lesion cases was highest in the month of August and lowest in the month of January, 2007-2012. CONCLUSION: This study shows that bovine tuberculosis is endemic in Plateau State. Trend analysis showed that bovine tuberculosis is seasonal and peaked mostly in July and August. Continuous surveillance through meat inspection is required to prevent zoonotic transmission of bovine tuberculosis.

Metabolic syndrome is associated with higher rates of cardiovascular morbidity and mortality. Although significant disparities in the risks of metabolic syndrome by occupation type and sex are well documented, the factors associated with metabolic syndrome in low- to middle-income countries remain unclear. These gaps in evidence identify the need for patterns of metabolic syndrome among hospital personnel of both sexes in Nigeria. A total of 256 hospital workers comprising 32.8% men were studied. The mean age of the participants was 42.03 ± 9.4 years. Using International Diabetic Federation criteria, the prevalence of metabolic syndrome was 24.2%. Women were substantially and significantly more likely to be identified with metabolic syndrome compared with men (34.9% vs 2.4%, respectively; P=.0001). This study identified metabolic syndrome among health workers with over one third of women with metabolic syndrome compared with <10% of men. These results support the implementation of lifestyle modification programs for management of metabolic syndrome in the health care workplace.

BACKGROUND: Basal skull fractures (BSF) in head injury may be missed clinically. Early detection ensures prompt treatment and prevention of complications We compared the clinical and Computed Tomography (CT) features of basal skull fractures in head injured patients in a southwestern Nigerian hospital. MATERIALS AND METHODS: Head injury patients who had cranial CT at a Southwestern Nigerian hospital were selected. CT images were acquired with a 64-slice Toshiba Aquillion CT scanner using a standard head protocol. The images were evaluated for evidence of skull fractures, and associated complications. The clinical data and CT findings were analyzed. RESULTS: One hundred and thirty patients were evaluated, including 103 (79.2%) males. Their ages ranged between 7 months and 81 years, mean 35 years (SD, 20.3). In 59 patients (45.4%, 59/130) BSF was detected on CT, while 71 (54.6%) had no evidence BSF. Forty-two (71.2%) of the 59 patients detected on CT had clinical suspicion of BSF (P < 0.001) while the remaining 17 (28.8%) were not clinically diagnosed. This equaled a sensitivity of 71.2% and, specificity of 90.1% for clinical determination of BSF in this study. There was no statistically significant difference between clinical and CT diagnosis (P > 0.05). The commonest observed clinical feature in patients with confirmed BSF was otorrhagia (45.8%) and the petrous temporal bone (45.8%) was the most commonly fractured bone. The BSF was caused most commonly by motor bike accidents in 53 (40.8%). The most common associated intracranial injuries were intracerebral haemorrhage (34.6%) and subdural (17.3%). CONCLUSION: It appears that neurosurgical evaluation is comparatively reliable in evaluating basal skull fractures in this study area even as they are consistently demonstrated by high resolution CT scanners. A clinical suspicion of BSF should warrant a closer detailed CT evaluation and reporting by radiologists.
RESUMO
INTRODUCTION: Bovine tuberculosis (BTB) is widespread yet poorly controlled in Nigeria hence posing a public health threat. This study determined the prevalence of Mycobacterium tuberculosis complex (MTC) and factors associated with MTC among slaughtered cattle at Jos South Abattoir in Plateau State, Nigeria. METHODS: We conducted a cross sectional study in which we collected 168 lung samples systematically from 485 slaughtered cattle from May-June, 2012, and tested for acid fast bacilli (AFB) using Ziehl-Neelsen test and a duplex polymerase chain reaction technique (PCR) for MTC detection. Data on cattle socio-demographic characteristics and risk factors for zoonotic BTB infection was obtained and analyzed using Epi info version 3.5.3 to determine frequency, proportions, and prevalence odds ratios. Multiple logistic regression was done at 95% Confidence Interval (CI). RESULTS: The mean age of the cattle was 5.6 ± 1.3 years and (108) 64.3% were females. Majority were indigenous White Fulani breed of cattle (58.5%) and about half (54.8%) were slightly emaciated. Prevalence of MTB complex was 21.4% by AFB test and 16.7% by duplex PCR. Of 33 (19.6%) lungs with lesions, 27 (81.8%) were positive for AFB; while of 135 (80.4%) lungs without lesions, 9 (6.7%) were positive for AFB. Lungs with lesions were 52 times more likely to test positive to AFB test compared to tissues without lesions (AOR=52.3; 95% CI: 16.4-191.8). CONCLUSION: The presence of MTC in cattle signifies its potential risk to public health. Presence of lesions on lungs is a reliable indicator of MTC infection that meat inspectors should look out for.

Driving is recognized to be a visually intensive task and accordingly legal minimum standard of vision required for all motorists is stipulated. This study was carried out to find out how many commercial drivers in Ibadan North L.G.A met minimum legal requirement for driving in Nigeria. A cross sectional descriptive study was conducted among 340 commercial vehicle drivers selected by multistage sampling from eight transport stations (motor parks) in the city. Visual impairment was defined as vision acuity (VA) in both eyes which is below 3/18 but above 3/60 (VA <6/18â¥3/60) and was assessed with the Snellen's chart. All participants have valid driving licenses. One sixth [52, (15.3%)] have visual acuity below 6/9 and 18 (5.3%) have visual impairment (VA <6/18â¥3/60). More of those drivers aged 40 years and more had visual impairment compared to the younger drivers (P<0.05). These findings suggest that regulatory standards for licensing drivers are being circumvented by some of the drivers. Mechanisms for ensuring compliance to the regulatory standards especially visual acuity is therefore recommended
