Picture Cards Versus Physical Examination: A Proof-of-Concept Study to Improve the SOSAS Survey Tool.

INTRODUCTION: The Surgeons OverSeas Assessment of Surgical Needs (SOSAS) survey tool is used to determine the unmet surgical needs in the community and has been validated in several countries. A major weakness is the absence of an objective assessment to verify patient-reported surgically treatable conditions. The goal of this study was to determine whether a picture portfolio, a tool previously shown to improve parental recognition of their child's congenital deformity, could improve the accuracy of the SOSAS tool by how it compares with physical examination. This study focused on children as many surgical conditions in them require prompt treatment but are often not promptly diagnosed. METHODS: We conducted a descriptive cross-sectional community-based study to determine the prevalence of congenital and acquired surgical conditions among children and adults in a mixed rural-urban area of Lagos, Southwest Nigeria. The picture portfolio was administered only to children and the surgical conditions to be assessed were predetermined using an e-Delphi process among pediatric surgeons. The modified The Surgeons OverSeas Assessment of Surgical Needs-Nigeria Survey Tool (SOSAS-NST) was administered to household members to collect other relevant data. Data were analyzed using the REDCap analytic tool. RESULTS: Eight hundred and fifty-six households were surveyed. There were 1984 adults (49.5%) and 2027 children (50.5%). Thirty-six children met the predetermined criteria for the picture portfolio-hydrocephalus (n = 1); lymphatic malformation (n = 1); umbilical hernia (n = 14); Hydrocele (n = 5); inguinal hernia (n = 10) and undescended testes (n = 5). The picture portfolio predicted all correctly except a case of undescended testis that was mistaken for a hernia. The sensitivity of the picture portfolio was therefore 35/36 or 97.2%. CONCLUSIONS: The SOSAS-NST has improved on the original SOSAS tool and within the limits of the small numbers, the picture portfolio has a high accuracy in predicting diagnosis in children in lieu of physical examination.

A Study of Knowledge of Occupational Health Hazards and Safety Practices among Automobile Mechanics in an Urban Area of South-Western Nigeria.

Background: Occupational diseases can result in sickness absence, economic loss, disability, or death of workers. Several studies have revealed that occupational health and safety practice is still low in some occupational groups despite their knowledge and the occupational health legislation. This study assessed the level of knowledge, attitude, and practices of automobile mechanics towards occupational health hazards and safety in a Local Government Area of Lagos State. Methodology: This descriptive cross-sectional study was conducted among 120 consenting registered automobile mechanics in the Surulere Local Government Area of Lagos State. A questionnaire was used to obtain information on socio-demography, occupational health history, knowledge, attitude, and practice of automobile mechanic workers towards health problems, associated hazards, and safety. Data entry and analysis were done with epi-info 3.5.1 (2008); Chi-square test and Fisher Exact test were used to test for significance. Results: In this study, 96.7% of the respondents had an overall knowledge of safety devices. However, further exploration revealed knowledge gaps in select safety devices. The percentage of the respondents with a good attitude was 26.7%, while the respondents who had an overall good practice towards occupational hazards and safety was 21.7%. In this study, the daily income and years of working experience were associated with knowledge of safety practices among automobile mechanics. Full-time automobile mechanic workers had a more positive attitude than those that engaged in part-time practice. Workers with formal training demonstrated better safety practices than those that were trained by apprenticeship. Conclusion: This study reflected the level of neglect experienced by this sector in terms of the regulated safety of its workers. The quality of supervision, regulation and training received by these automobile mechanics was sub-standard.

COVID-19: A review of the effectiveness of non-pharmacological interventions.

COVID-19, a highly infectious disease, caused by a novel virus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has brought about an unprecedented threat to global health. First reported in Wuhan, China, in December 2019, it has now spread to all continents of the world becoming a pandemic. There is no known treatment or vaccine for it although many candidate drugs and vaccines are in various clinical trial phases. For now, non-pharmacological interventions (NPIs) have become the mainstay of response for COVID-19 and are being used across the world to flatten the epidemiologic curve with some success. This review focussed on identifying which NPIs have been effective. NPIs that are effective include isolation and quarantine, physical distancing, use of face masks and hand hygiene. These measures are best used in combination and simultaneously. The evidence is that they should be instituted early in the pandemic and for sustained periods. They should also be implemented in the context of the cultural and socioeconomic conditions of the populace. Ineffective NPIs include ultraviolet irradiation and spraying of outdoor spaces and individuals. We recommend that decision makers weigh the evidence carefully, as it applies to the local setting to inform public health decisions.

Prevalence of surgically correctable conditions among children in a mixed urban-rural community in Nigeria using the SOSAS survey tool: Implications for paediatric surgical capacity-building.

BACKGROUND: In many low- and middle-income countries, data on the prevalence of surgical diseases have been derived primarily from hospital-based studies, which may lead to an underestimation of disease burden within the community. Community-based prevalence studies may provide better estimates of surgical need to enable proper resource allocation and prioritization of needs. This study aims to assess the prevalence of common surgical conditions among children in a diverse rural and urban population in Nigeria. METHODS: Descriptive cross-sectional, community-based study to determine the prevalence of congenital and acquired surgical conditions among children in a diverse rural-urban area of Nigeria was conducted. Households, defined as one or more persons 'who eat from the same pot' or slept under the same roof the night before the interview, were randomized for inclusion in the study. Data was collected using an adapted and modified version of the interviewer-administered questionnaire-Surgeons OverSeas Assessment of Surgical Need (SOSAS) survey tool and analysed using the REDCap web-based analytic application. MAIN RESULTS: Eight-hundred-and-fifty-six households were surveyed, comprising 1,883 children. Eighty-one conditions were identified, the most common being umbilical hernias (20), inguinal hernias (13), and wound injuries to the extremities (9). The prevalence per 10,000 children was 85 for umbilical hernias (95% CI: 47, 123), and 61 for inguinal hernias (95% CI: 34, 88). The prevalence of hydroceles and undescended testes was comparable at 22 and 26 per 10,000 children, respectively. Children with surgical conditions had similar sociodemographic characteristics to healthy children in the study population. CONCLUSION: The most common congenital surgical conditions in our setting were umbilical hernias, while injuries were the most common acquired conditions. From our study, it is estimated that there will be about 2.9 million children with surgically correctable conditions in the nation. This suggests an acute need for training more paediatric surgeons.

Spectrum of Thyroid Abnormalities among Children Living with HIV in Lagos, Nigeria.

Thyroid disorders have been described in an adult population but are underreported in the pediatric population. The aim of this study was to determine the prevalence and describe the spectrum of thyroid abnormalities among HIV infected children on Highly Active Antiretroviral Therapy (HAART) in Lagos, Nigeria. This was a cross-sectional study carried out at a teaching hospital with an antiretroviral therapy (ART) center. Serum levels of thyroid stimulating hormone (TSH), free triiodothyronine (fT3), and free thyroxine (fT4) were analyzed in 83 children living with HIV on HAART and 51 controls. The prevalence of thyroid dysfunction and correlation of fT3, fT4, and TSH with duration on HAART, age, CD4 count, and nutritional status were assessed. Thyroid abnormalities were seen in 9.6% of the children living with HIV comprising subclinical hypothyroidism in 6%, euthyroid sick syndrome in 2.4%, and overt hypothyroidism in 1.2% as compared to 2% subclinical thyroid disease among the controls (p= 0.15). Hypothyroidism was correlated with CD4 count and viral load. None of the patients had clinical features of thyroid disease. Thyroid abnormalities were more prevalent among children living with HIV and yearly screening with follow-up is advocated.

Are Nigerian Women Pro-Active about Noncommunicable Disease Prevention? A Quantitative Survey.

BACKGROUND: Noncommunicable diseases (NCDs) continue to cause significant morbidity and mortality worldwide with incidence increasing rapidly in developing countries. Poor utilization of preventive healthcare services contributes to this high burden. OBJECTIVE: To assess the knowledge and utilization of preventive healthcare services among women in Lagos, Nigeria. METHODS: This was a cross-sectional descriptive study carried out at Mainland Local Government Area (LGA) between May and July 2014. Respondents were selected using the multistage sampling method. A pretested, interviewer-administered questionnaire was used to obtain information. Data were analyzed using Epi info software version 7. Summary and inferential statistics were done and the level of significance was set at <5% (p < 0.05). FINDINGS: Awareness of specified NCDs among the 322 respondents was 82.61% and of preventive healthcare services for the NCDs was 65.22%. Virtually all (99.05%) of the respondents had poor knowledge of these preventive services. Utilization rates were equally poor. Most common screening/tests done were Blood Pressure measurement (78.18%), Self breast examination (69.96%) and blood sugar test (58.33%). Much lower utilization rates were recorded for lipid profile (37.57%), Pap smear (26.11%), Visual Inspection with Acetic Acid (VIA) (19.72%), Human Papilloma Virus (HPV) immunization (16.55%) and mammography (14.72%). CONCLUSIONS: Respondents were aware of specified NCDs and preventive healthcare services. They considered routine medical check-up important, however they had poor knowledge of the preventive health services for NCDs and hardly utilized them. Women should be given detailed information on the preventive healthcare services to improve their knowledge and utilization so as to reduce the NCD burden.

A malariometric survey of under-fives residing in indoor residual spraying-implementing and non-implementing communities of Lagos, Nigeria.

BACKGROUND: Indoor residual spraying (IRS) is used as part of the integrated vector management strategy for the control of malaria in Lagos, Nigeria. The purpose of this study was to compare the malariometric indices of children under 5 years old living in IRS-implementing and non-IRS-implementing communities of Lagos, Nigeria. METHODS: The study was a community-based, comparative, cross-sectional study of 480 children under five recruited using a multi-stage sampling method. Data on each child were collected using a household questionnaire administered to the consenting care-giver of each selected child. Each child underwent a comprehensive physical examination. On-the-spot malaria rapid diagnostic testing and haemoglobin estimation to assess parasitaemia and anaemia, respectively, were also carried out. Risk factors for parasitaemia and anaemia were identified using multivariate logistic regression. RESULTS: A total of 238 children were studied in the IRS-implementing group while 242 children were studied in the non-IRS-implementing group. The IRS -implementing community had a lower level of parasitaemia (1.3 %) compared to the non-IRS-implementing community (5.8 %) (p < 0.001). There was no significant difference in anaemia, spleen rate and fever in the IRS-implementing group (10.9, 9.7 and 5 %) and the non-IRS-implementing group (9.9, 8.8 and 8.7 %), respectively. Residing in an IRS-implementing community was associated with lower odds of parasitaemia (OR 0.17, p < 0.01). Sleeping under a bed net was the only factor associated with anaemia (p < 0.01). CONCLUSION: IRS has led to a reduction in the level of parasitaemia in the under-fives in the study areas.
