Prospective assessment of the risk of obstructive sleep apnea in patients attending a tertiary health facility in Sub-Saharan Africa

Introduction The impact of Obstructive sleep apnea (OSA) in worsening outcomes is profound, especially in the presence of comorbid conditions. This study aimed to describe the proportion of patients at a high risk of OSA in our practice setting. Methods The STOP BANG questionnaire and the Epworth Sleepiness scale were used to assess for OSA risk and excessive daytime sleepiness respectively. Hospitalized patients and out-patients were recruited. Intergroup differences in continuous variables were compared using the analysis of variance. The proportion of patients with high risk of OSA and excessive daytime sleepiness was presented as frequencies and group differences compared with the Pearson χ2 test. Independent risk predictors for OSA were assessed in multivariate logistic regression analysis. Results A total of 1100 patients (53.4% females) participated in the study. Three hundred and ninety nine (36.3%) had a high risk of OSA, and 268 (24.4%) had excessive daytime sleepiness. Of the participants with high OSA risk, 138 (34.6%) had excessive daytime sleepiness compared to 130 (18.5%) of those with low OSA risk (p). Conclusion A significant proportion of patients attending our tertiary care center are at high risk of OSA.

Prevalence of Tinea capitis infection among primary school children in a rural setting in south-west Nigeria

Dermatophyte infection is a common skin disorder. Tinea capitis, infection of the scalp and hair shaft, is the most common dermatophytosis in children aged between six months and pre-pubertal age. The aim of the study was to determine the prevalence, causative agents and to identify predisposing factors among primary school children in a rural community in Sagamu, Ogun state, Nigeria. This was a descriptive cross sectional study. Interviewer administered questionnaire was used. Following a physical examination, children with a clinical diagnosis of tinea capitis had scalp and hair scrapings for microscopy and culture. Tinea capitis was confirmed in 15.4%. Trichophyton mentagrophyte (51.7%) and Microsporum aoudouinii (20.7%) were the most prevalent organisms in this study. The most common predisposing factors were carrying of objects on the scalp; sharing of hair clippers, scissors, combs, towels and fomites. Low socioeconomic status coupled with overcrowding and poor hygiene was the major determinant of tinea capitis among the children. Tinea capitis remains a common infection among Nigerian school children. Health promotion and health education interventions are recommended to promote good hygiene, better living conditions, early identification and treatment.

Prevalence and pattern of urinary abnormalities among apparently healthy adult Nigerians

Background: Urinalysis is a simple and cheap method of screening for systemic diseases including kidney disease and may open a window of opportunity for prevention/early treatments especially in resource-constrained settings like Nigeria. We therefore studied the pattern of urinary abnormalities among an apparently healthy urban population. Methods: Mid-stream clean catch urine samples were collected from 1048 apparently healthy subjects and tested for urinary abnormalities using the dipstick method following a health promotional talk in Idi-araba, a Lagos slum. Results: A total of 1048 randomly selected subjects with a mean age of 38.7 ΁ 14.5 years (age range 18-85 years) were screened. This consisted of 597 (57%) females and 451 (43%) males. Protenuria, hematuria, leucocyturia, nitrituria, and glucosuria were present in 18.9%, 1.7%, 9.2%, 1.8% and 2% of the subjects respectively. Proteinuria and haematuria was more prevalent in subjects aged ≥40 years (P < 0.05). The prevalence of leucocyturia, nitrituria, and glucosuria were independent of age (P < 0.05). There were no gender differences in the prevalence of urinary abnormalities (P < 0.05). Four hundred and forty-four (42.3%) of the cohort had hypertension (HTN). Proteinuria and leucocyturia were more prevalent in hypertensive subjects (P < 0.05) while hematuria, nitrituria, and glucosuria was independent of hypertensive status of subjects (P < 0.05). Conclusion: Urinary abnormalities are common among apparently healthy adults in Lagos. It is therefore recommended that it should be routinely done as a cheap screening tool and further evaluation conducted where necessary. This may result in cheaper treatment and better outcomes.

Cooking Fuels in Lagos, Nigeria: Factors Associated with Household Choice of Kerosene or Liquefied Petroleum Gas (LPG)

Cooking with dirty-burning fuels is associated with health risk from household air pollution. We assessed the prevalence of and factors associated with the use of cooking fuels, and attitudes and barriers towards use of liquefied petroleum gas (LPG). This was a cross-sectional, population-based survey conducted in 519 households in Lagos, Nigeria. We used a structured questionnaire to obtain information regarding choice of household cooking fuel and the attitudes towards the use of LPG. Kerosene was the most frequently used cooking fuel (n = 475, 91.5%; primary use n = 364, 70.1%) followed by charcoal (n = 159, 30.6%; primary use n = 88, 17%) and LPG (n = 86, 16.6%; primary use n = 63, 12.1%). Higher level of education, higher income and younger age were associated with LPG vs. kerosene use. Fuel expenditure on LPG was significantly lower than for kerosene (N (Naira) 2169.0 ± 1507.0 vs. N2581.6 ± 1407.5). Over 90% of non-LPG users were willing to switch to LPG but cited safety issues and high cost as potential barriers to switching. Our findings suggest that misinformation and beliefs regarding benefits, safety and cost of LPG are important barriers to LPG use. An educational intervention program could be a cost-effective approach to improve LPG adoption and should be formally addressed through a well-designed community-based intervention study.

Clinico-etiologic profile of hand dermatitis and patch response of patients at a tertiary hospital in Lagos, Nigeria: results of a prospective observational study

Hand dermatitis is an acute or chronic inflammation of the skin of the hands from a multifactorial cause which may be endogenous, exogenous, or a combination of both. With a wide range in severity and recurrent periods of flares, it has significant impact on the quality of life of its sufferers. A history of atopy predisposes patients to hand dermatitis, but contact dermatitis, either allergic or irritant, is the more commonly implicated factor in the etiology of hand dermatitis. Patch testing is an important tool in identifying the allergen responsible for allergic hand dermatitis, and this knowledge will contribute to improved management.

Clinical pattern of psoriasis in patients seen at a tertiary hospital in Nigeria

Background and Objectives: Psoriasis is a chronic, papulosquamous disorder of the skin with variable morphology, characterized by periods of remission and reactivity. Psoriasis is less common in the tropics and in dark-skinned persons. Prevalence in West Africans has been noted to be similar to that of the African-Americans suggesting a similarity in genetic ancestry. This study aimed to describe the clinical characteristics of psoriasis and precipitating factors in Nigerian patients. Materials and Methods: This is a retrospective study of all dermatology patients with features of psoriasis who attended the dermatology outpatient clinic of the hospital between January 2007 and May 2012. Data were obtained from the patients′ clinic notes and protocol for psoriasis, which documented patients′ demographic data, clinical presentations, and precipitating factors. Results: Psoriasis was found in 1.13% (124/11,015) of the study population. There was a male preponderance with a male to female ratio of 1.34:1. The majority of patients seen were in the fourth decade of life. Stress, alcohol, and drugs were the most reported predisposing factors to psoriasis. All types of psoriasis were found, and plaque psoriasis was the most common. Conclusion: This study confirms the increasing frequency of psoriasis among dermatology patients in Nigeria, which may either be due to an increased proficiency in diagnosing the condition by physicians or increase prevalence of environmental factors. The current trend in the management of psoriasis is focused on treating the inflammatory process as well as managing the modifiable environmental triggers.
