Background: Depression among adolescents has been recognized as a public health problem all over the world. In Nigeria, as in most developing countries, there is a need for more research on the epidemiology of adolescent depression as this will guide prevention, diagnosis and treatment. Objectives: The study sought to determine the one month prevalence and predictors of depression among a sample of in-school adolescents in a rural region in South West Nigeria. Materials and Methods: This was a cross sectional descriptive survey among 540 secondary school students randomly selected from the six secondary schools in the study area using a Socio demographic Questionnaire and the Patient Health Questionnaire modified for Adolescents. Subsequently, a proportion of them were interviewed with the Kiddies Schedule for Affective Disorders and Schizophrenia. Results: Data were analyzed using the SPSS version 17. Respondents were aged 10 -19 years (mean age was 14.07 ± 1.84). The one month prevalence of depression among the study population was 16.3% (using weighting method). Logistic regression analysis showed that death of a mother (OR = 11.786, 95% CI, 1.990 -23.184), being from a polygamous family (OR = 5.781, 95% CI, The one month prevalence of adolescent depression within the study population is slightly higher than what has been reported in other parts of the world. Therefore, there is a need for government to design and implement policies which can help to prevent, detect early, and treat depression among youths especially in rural areas.

Background: Drugs that kill or inhibit sexual stages of Plasmodium such as Primaqiune (PQ) could potentially amplify or synergize the impact of first line antimalarials by blocking transmission to mosquitoes. This study examined the effect of Primaquine on gametocyte carriage in the case management of uncomplicated falciparum malaria with artemisinin-based combination therapy (ACT) with the overall purpose of possibly recommending it as an adjunct drug for malaria control. Methods: A total of 181 patients with uncomplicated falciparum malaria, normal glucose-6-phosphate dehydrogenase (G6PD) enzyme levels, and haemoglobin levels ≥ 8 g/dL completed this two-arm randomized blinded clinical trial to test the efficacy of a single dose PQ (0.75 mg/kg) on falciparum gametocytaemia. 88 subjects were assigned to a standard 3-day course of Dihydroartemisinin-Piperaquine (DHP) alone (n = 88) while 93 others had DHP combined with a single dose of PQ on day 3 (n = 93). A 28-day follow-up schedule carried out in the outpatient clinic of a Primary health facility in Vom, Plateau State Nigeria where study participants were seen on days 1, 3, 7 and then weekly to assess the presence of asexual parasites and gametocytes by microscopy. A Kaplan-Meier analysis was employed to determine the survival function of gametocytes on day 3. The data was analyzed using Epi info version 7.1.5. Results: With a gametocyte prevalence of 27.1%, gametocyte carriage rate was lower in the PQ group due to higher probability of clearing gametocytes (Breslow test χ 2 = 8.306, df = 1, p = 0.004) and significantly less likely to harbor gametocytes by day 7 when compared to the DHP-alone group (χ 2 = 6.218, df = 1, p = 0.013). Conclusion:Addition of single-dose 0.75 mg/kg PQ was associated with reduced gameto-
