Prevalence and impact of primary headaches among students aged 8-12 years in Sub-Saharan Africa: Cameroon experience.

BACKGROUND: The present study aimed to investigate the prevalence and impact of primary headache among students aged 8-12 years in the city of Douala (Cameroon). METHODS: From January to May 2022, a cross-sectional study was conducted in 52 primary schools randomly selected from five districts in the city of Douala. The study population consisted of primary school students in level III classes. The diagnosis of primary headache was made according to the International Classification of Headache Disorders, 3rd ed (ICHD-3) criteria and the paediatric version of the HARDSHIP questionnaire was used for recruitment. RESULTS: In total, 2056 students participated of whom 55.9% (n = 1149) were female, with a median age of 11 years. The prevalence of headache in the last 12 months was 85.7% (n = 1762), that of migraine was 26.1% (n = 536) and that of tension-type headache (TTH) was 15.1% (n = 311). Regarding the impact of primary headaches, 176 (32.8%) migraineurs reported absenteeism from school compared to 70 (22.5%) students with TTH (p = 0.03) and 309 (57.6%) migraineurs had a break in their activities compared to 147 (47.3%) students with TTH (p < 0.01). CONCLUSIONS: Primary headaches are common among students aged 8-12 years in the city of Douala. They are responsible for a considerable impact on children and their family, particularly for migraineurs.

Antifungal Combinations for Treatment of Cryptococcal Meningitis in Africa.

BACKGROUND: Cryptococcal meningitis accounts for more than 100,000 human immunodeficiency virus (HIV)-related deaths per year. We tested two treatment strategies that could be more sustainable in Africa than the standard of 2 weeks of amphotericin B plus flucytosine and more effective than the widely used fluconazole monotherapy. METHODS: We randomly assigned HIV-infected adults with cryptococcal meningitis to receive an oral regimen (fluconazole [1200 mg per day] plus flucytosine [100 mg per kilogram of body weight per day] for 2 weeks), 1 week of amphotericin B (1 mg per kilogram per day), or 2 weeks of amphotericin B (1 mg per kilogram per day). Each patient assigned to receive amphotericin B was also randomly assigned to receive fluconazole or flucytosine as a partner drug. After induction treatment, all the patients received fluconazole consolidation therapy and were followed to 10 weeks. RESULTS: A total of 721 patients underwent randomization. Mortality in the oral-regimen, 1-week amphotericin B, and 2-week amphotericin B groups was 18.2% (41 of 225), 21.9% (49 of 224), and 21.4% (49 of 229), respectively, at 2 weeks and was 35.1% (79 of 225), 36.2% (81 of 224), and 39.7% (91 of 229), respectively, at 10 weeks. The upper limit of the one-sided 97.5% confidence interval for the difference in 2-week mortality was 4.2 percentage points for the oral-regimen group versus the 2-week amphotericin B groups and 8.1 percentage points for the 1-week amphotericin B groups versus the 2-week amphotericin B groups, both of which were below the predefined 10-percentage-point noninferiority margin. As a partner drug with amphotericin B, flucytosine was superior to fluconazole (71 deaths [31.1%] vs. 101 deaths [45.0%]; hazard ratio for death at 10 weeks, 0.62; 95% confidence interval [CI], 0.45 to 0.84; P=0.002). One week of amphotericin B plus flucytosine was associated with the lowest 10-week mortality (24.2%; 95% CI, 16.2 to 32.1). Side effects, such as severe anemia, were more frequent with 2 weeks than with 1 week of amphotericin B or with the oral regimen. CONCLUSIONS: One week of amphotericin B plus flucytosine and 2 weeks of fluconazole plus flucytosine were effective as induction therapy for cryptococcal meningitis in resource-limited settings.

Outcome of non-traumatic coma in a tertiary referral hospital in Cameroon.

Introduction: Coma is a medical emergency, and optimal management, especially in a resource-poor setting, depends on knowledge of its aetiology and predictors of outcome. This study aimed to provide hospital-based data on the prevalence, etiology, and outcome of non traumatic coma (NTC) in adults at a tertiary level in Cameroon. Methods: A three year retrospective cohort study of medical records of patients aged 18 years and above, who presented in coma of non-traumatic origin at a Cameroon emergency department (ED) was conducted. Data related to sociodemographic, clinical findings, investigations, etiology of the coma, and outcomes were collected. Results: A total of 408 patients were recruited, 214 (52.5 %) were males. The mean age was 55.9 ± 16.6 years. NTC accounted for 2.2 % of all consultations at the ED during the period of study. Stroke (29.6 %), infections (19.8 %), and metabolic disorders (12.6 %) were the most frequent cause of NTC. Etiology was unknown in 23.3 % of our participants. The in-hospital mortality was 66.4 %. Duration of hospitalization ≤ 3 days, GCS 〈 6, serum creatinine level 〉 13 mg/L, and administration of adrenergic drugs were predictors of mortality. Overall survival rate was 44.3 % after 5 days of admission. Conclusion: Non-traumatic coma had various aetiologies. Stroke accounted for almost one third of cases. About three out of five patients died in hospital. Deep coma, high serum creatinine level, short hospital stay and administration of adrenergic medications were independent predictors of mortality.

The spectrum of skin diseases in a rural setting in Cameroon (sub-Saharan Africa).

BACKGROUND: Skin disorders are generally considered to be more prevalent in the rural areas of Cameroon. This study was carried out to verify this assumption by describing the spectrum of skin disorders in a rural setting of Cameroon. METHODS: We carried out a community-based clinical skin examination of 400 consenting subjects from 4 villages of Cameroon: Nyamanga (27%), Yebekolo (24%), Mbangassina (23%) and Bilomo (26%). RESULTS: The overall prevalence of skin diseases in our sample was 62% {95% CI: 57.2%, 66.8%} (248/400). The commonest skin disorders were: fungal infections (25.4%), parasitic infestations (21.4%), atrophic skin disorders (11.7%), hypertrophic skin disorders (9.7%), disorders of skin appendages {acne} (8.9%), benign neoplasm (6.5%), bacterial skin infections (5.2%), pigmentation disorders (4.8%), and dermatitis/eczema (4.0%). Skin infections and infestations constituted 52.82% of all skin disorders. The overall prevalence of infectious and parasitic infestation was 32.75% {95%CI: 28.17%, 37.59%} (131/400) as against 29.25% {95%CI: 24.83%, 33.98%} (117/400) for non-infectious disorders.Among people with skin infections/parasitic infestations, those with fungal infections and onchocercal skin lesions were the most prevalent, accounting for 48.1% (63/131) and 35.1% (46/131); and an overall prevalence of 15.75% {95%CI: 12.3%, 19.7%} (63/400) and 11.5% {95%CI: 8.5%, 15.0%} (46/400) respectively.There was secondary bacterial infection in 12.1% {95%CI: 8.31%, 16.82%} (30/248) of subjects with skin diseases. Hypertrophic and atrophic disorders of the skin were mainly keloids (9.68%), scarification marks (6.05%) and burn scars (5.65%). Skin diseases like dermatitis and eczema (4.03%), malignant tumours and pigmentation disorders were rare in our sample.The proportion of subjects diagnosed with skin disorders after examination (62.8%) was significantly higher than the proportion of 40.8% that declared having skin diseases (p < 0.0001). CONCLUSION: The prevalence of skin diseases in the rural Mbam valley is alarming, dominated by easily treatable or preventable skin infections and their magnitude is highly neglected by the community, contrasting with findings in the urban setting. Similar studies are needed in other ecological/demographic settings of the country in order to construct a better understanding of the epidemiology of skin disorders. This would lead to the development of national policies to improve skin care.

Leave no one behind: response to new evidence and guidelines for the management of cryptococcal meningitis in low-income and middle-income countries.

In 2018, WHO issued guidelines for the diagnosis, prevention, and management of HIV-related cryptococcal disease. Two strategies are recommended to reduce the high mortality associated with HIV-related cryptococcal meningitis in low-income and middle-income countries (LMICs): optimised combination therapies for confirmed meningitis cases and cryptococcal antigen screening programmes for ambulatory people living with HIV who access care. WHO's preferred therapy for the treatment of HIV-related cryptococcal meningitis in LMICs is 1 week of amphotericin B plus flucytosine, and the alternative therapy is 2 weeks of fluconazole plus flucytosine. In the ACTA trial, 1-week (short course) amphotericin B plus flucytosine resulted in a 10-week mortality of 24% (95% CI -16 to 32) and 2 weeks of fluconazole and flucytosine resulted in a 10-week mortality of 35% (95% CI -29 to 41). However, with widely used fluconazole monotherapy, mortality because of HIV-related cryptococcal meningitis is approximately 70% in many African LMIC settings. Therefore, the potential to transform the management of HIV-related cryptococcal meningitis in resource-limited settings is substantial. Sustainable access to essential medicines, including flucytosine and amphotericin B, in LMICs is paramount and the focus of this Personal View.
