Third molar (M3) extraction is an anxiety-provoking procedure. Information mode delivery may affect patients' anxiety level and postoperative sequelae. This study determined the relationship between information types, dental anxiety, and postoperative pain following mandibular M3 extraction.Patients (aged 18 to 35 years) requiring M3 extraction under local anesthesia were recruited into this prospective randomized study conducted in Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife. Patients were randomized to two groups; verbal or audiovisual depending on M3 extraction information received. Primary outcome variable (difference in anxiety between groups) was assessed with State-Trait Anxiety Inventory (STAI-S) and Modified Dental Anxiety Scale(MDAS). Pain recorded on postoperative days (PODs) 1, 3, and 7 using the Visual Analog Scale was the secondary outcome. Other covariables include biodata, impaction types, and difficulty indices. Data analysis was descriptive and bivariate using IBM/SPSS for Windows, version 23 (SPSS, Chicago, IL USA) with significance set at P .05.Ninety patients referred for M3 extraction met the inclusion criteria, 45 patients in each group. The audiovisual group had significant increase in anxiety preoperatively measured by STAI-S (P = .002) and MDAS (P = .009) when compared with the verbal group. No significant differences in the STAI-S (P = .16) and MDAS (P = .216) scores were recorded at POD7. The progressive reduction in pain in both groups was not significant at POD7 (P = .746).Preoperative verbal information allayed anxiety compared to real life audiovisual information in M3 patients. These findings will provide a baseline reference data for subsequent research in our environment.

Background: Mucous Retention Cyst (MRC) are non-neoplastic, developmental salivary gland lesion. Although more common in the minor salivary gland, few cases have been reported in the major salivary gland. Objective: To draw the attention of clinicians to a rare occurrence of MRC in the submandibular gland bilaterally. Case Report: The index case presents as a slowly progressive painless lesion of 10 years duration associated with aesthetics concerns. The lesion appeared as a double jaw with extension into the neck. Though lobulated and fluctuant, aspirate yielded yellow coloured, non-viscous and non-foul smelling fluid. Ultrasonography revealed a multilobulated mass with mobile heterogeneous fluid-like content in the submental and submandibular regions bilaterally. The massive size of the lesion limited the ultrasonic visualization of the submandibular salivary glands. The patient could not afford advanced imaging. During surgery, the lesion had involved the submandibular gland bilaterally with attachment to the hyoid bone and in close relation to the recurrent laryngeal nerve. Although the nerve was preserved, the patient experienced temporary hoarseness, which resolved with medication. Histopathologic examination of the excised lesion revealed the lesion as Mucous Retention Cyst. Conclusion: The massive size of the lesion, delayed presentation and financial constraints in obtaining advanced imaging could have contributed to the diagnostic dilemma. This rare case will help the clinicians include MRC as a differential diagnosis of lesions involving submandibular salivary gland bilaterally. It also draws the attention of the maxillofacial surgeons to the unexpected injury to the recurrent laryngeal nerve and its management in a low-income setting environment.

It is important to evaluate the level of bone-specific alkaline phosphatase as it relates to the quantity of callus formed in mandibular fracture healing. The objective of the present study was to assess Serum Bone-Specific Alkaline Phosphatase (BsALP) as an indicator of callus formation in patients with mandibular fracture and determine the relationship between BsALP and callus formation using two treatment methods. Fifty-five patients with isolated mandibular fractures were enrolled. BsALP was measured at presentation, 3rd and 6th week. The patients were recruited into two treatment groups: Closed Reduction with Mandibulomaxillary Fixation (MMF) and Open Reduction and Internal Fixation (ORIF). The Callus Index was measured at 3rd and 6th week after treatment using digital postero-anterior view of the jaws on DICOM viewer software. The mean value of BsALP was 26.2±9.5 ng/mL. BsALP concentration in patients with double site fractures was higher than those with a single fracture, p=0.102. Peak serum BsALP observed in the 3rd week post-intervention was (28.1±8.2 ng/mL). Statistically significant differences were observed between the BsALP concentration in the 3rd and 6th week, and between BsALP concentration at presentation and 6th week, p

Malignancies of salivary gland origin are rare in children. Mucoepidermoid carcinoma (MEC) is the most common histologic type of salivary gland neoplasm in pediatrics. We report a rare case of parotid MEC in a 20-month-old female patient. The tumor was composed of nests of epidermoid cells with nuclei appearing vesicular, pleomorphic, and hyperchromatic with an admixture of mucous cells and cystic spaces within a prominent connective tissue stroma. Immunohistochemically, the epidermoid cells showed cytokeratin 7 and P63 positivity, and mucous cells were positive for mucicarmine. Molecularly, this case was positive for MAML2 rearrangement by FISH. To our knowledge, this is one of the youngest cases of MEC of the parotid gland reported in the English literature.

The educational environment is an important factor in nurturing students' learning. Students' experiences of the climate of their learning environment positively correlate with their academic success, achievements and satisfaction.The study aimed to determine the perceptions of medical and dental students about their learning environment during anatomical pathology clinical placement.A prospective, cross-sectional study using a guided self-administered Dundee Ready Education Environment Measurement (DREEM) questionnaire was conducted among fourth year medical and fifth-year dental students on anatomical pathology placement at the College of Health Sciences, Obafemi Awolowo University Ile-Ife, Nigeria. One hundred and eleven of 118 students participated in the study.The age range was 19-35 years. The majority of the students were males ( n= 80, 72.1%). The overall mean score was 115.19 ± 25.6 (maximum obtainable total score = 200), indicating that the students perceived their learning environment as more positive than negative. The mean score for each subscale of the DREEM instrument was: 29.24/48 (60.9%) for perception of learning; 25.67/44 (58.3%) for perception of teaching; 20.89/32 (65.3%) for academic self-perception; 25.61/48(53.4%) for perception of the atmosphere of learning; and 13.52/28 (48.3%) social self-perception. No statistically significant difference was found by sex, age group, and course of study for each DREEM domain.Students' perception regarding the learning environment for anatomical pathology in the focal university shows the need for improvement across various domains. However, academic self-perception and social self-perception are the areas of greatest need.L’environnement éducatif est un facteur important pour favoriser l’apprentissage des élèves.

This study determined the effect of platelet-rich fibrin (PRF) on extraction socket bone regeneration and assessed the patterns and determinants of bone regeneration after the surgical extraction of impacted mandibular third molars.This prospective study randomly allocated 90 patients into two treatment groups: A PRF group (intervention group) and a non-PRF group (control group). After surgical extractions, the PRF group had PRF placed in the extraction socket and the socket was sutured, while the socket was only sutured in the non-PRF group. At postoperative weeks 1, 4, 8, and 12, periapical radiographs were obtained and HLImage software was used to determine the region of newly formed bone (RNFB) and the pattern of bone formation. The determinants of bone regeneration were assessed. Statistical significance was set atThe percentage RNFB (RNFB%) was not significantly higher in the PRF group when compared with the non-PRF group at postoperative weeks 1, 4, 8, and 12 (Placement of PRF in extraction sockets increased socket bone regeneration. However, this finding was not statistically significant. The patient's sex, type of impaction, and duration of surgery significantly influenced the percentage of bone formation.

BackgroundCOVID-19 pandemic widely disrupted health services provision, especially during the lockdown period, with females disproportionately affected. Very little is known about alternative healthcare sources used by women when access to conventional health services became challenging. This study examined the experiences of women and adolescent girls regarding access to sexual and reproductive health (SRH) services during the COVID-19 lockdown in Nigeria and their choices of alternative healthcare sources.MethodsThe study sites were two northern states, two southern states, and the Federal Capital Territory. Qualitative data were obtained through 10 focus group discussion sessions held with married adolescents, unmarried adolescents, and older women of reproductive age. The data were transcribed verbatim and analysed using a thematic approach and with the aid of Atlas ti software.ResultsWomen reported that access to family planning services was the most affected SRH services during the COVID-19 lockdown. Several barriers to accessing SRH services during COVID-19 lockdown were reported, including restriction of vehicular movement, harassment by law enforcement officers, fear of contracting COVID-19 from health facilities, and fear of undergoing compulsory COVID-19 tests when seeking care in health facilities. In the face of constrained access to SRH services in public sector facilities during the COVID-19 lockdown, women sought care from several alternative sources, mostly locally available and informal services, including medicine vendors, traditional birth attendants, and neighbours with some health experience. Women also widely engaged in self-medication, using both orthodox drugs and non-orthodox preparations like herbs. The lockdown negatively impacted on women’s SRH, with increased incidence of sexual- and gender-based violence, unplanned pregnancy resulting from lack of access to contraceptives, and early marriage involving adolescents with unplanned pregnancies. ConclusionCOVID-19 negatively impacted access to SRH services and forced women to utilise mostly informal service outlets and home remedies as alternatives to conventional health services. There is a need to ensure the continuity of essential SRH services during future lockdowns occasioned by disease outbreaks. Also, community systems strengthening that ensures effective community-based health services, empowered community resource persons, and health-literate populations are imperative for overcoming barriers to healthcare access during future lockdowns.

IntroductionRealist evaluation studies have spanned different aspects of medicine, especially in the field of public health. However, very few of these studies explicitly detailed how program implementation triggered outcomes that could strengthen understanding of its effect on Health System Strengthening in specific settings. In low- and middle-income countries, like Nigeria, there is a paucity of realist evaluation studies, despite the implementation of multiple intervention programs and projects in these countries. This article is aimed at unveiling the black-box of program implementation and Health System Strengthening of the “Abiye” Safe Motherhood Program in Ondo State, Nigeria. Specifically, it identified the role of contextual factors in the “Abiye” program in Ondo State, determined the mechanisms that facilitated or constrained outcomes of the “Abiye” program, and developed a Context Mechanism Outcome (CMO) Configuration from which a Middle Range Theory (MRT) can be framed.MethodologyThis was qualitative research structured along with the realist domains (Context, Mechanism, and Outcome). The Initial Program Theory was validated by the qualitative study, after which a new MRT was developed. The study population comprised key stakeholders, secondary stakeholders, and primary stakeholders in the Abiye safe motherhood program. Data was collected through 10 key informant interviews, 28 in-depth interviews, and six focus group discussions sessions. Thematic analysis was used to analyze all the qualitative data collected, and seven themes with 19 subthemes emerged in the study.ResultsWe identified 13 contextual factors under five principal areas, with most of the factors playing enabling roles, some playing inhibitory roles, while very few played both roles. We elicited eight mechanisms, and some of these facilitated the outcomes, while some constrained the outcomes of the program. Health system strengthening was a key feature of the outcome of the program. We developed a middle-range theory based on the 6 CMO configurations we elicited from the study.Conclusion and Policy ImplicationsRealist evaluation is an iterative process that looks beyond the surface to generate evidence. By applying the realist approach, we generated pieces of evidence that can be adapted for policymaking in public health interventions in LMIC.

IntroductionThe perception of mothers about causes of underweight and overweight among children or adolescents and associated cultural beliefs may influence nutritional status. However, data from qualitative studies on this subject and regarding age 6–19 are scarce in Nigeria.ObjectiveThis study aimed to explore mothers’ perceptions and cultural beliefs about underweight and overweight children and adolescents in selected communities in a northern and a southern Nigerian state.DesignThis was a qualitative study using focus group discussions (FGD). Eight FGD sessions were held. The interviews were transcribed verbatim, and the transcripts were coded and analysed using NVivo V.11, and direct quotations representing the themes generated from the perspectives were cited as appropriate.SettingThe study was carried out in eight randomly selected rural and urban communities in Gombe and Osun states of Nigeria.ParticipantsSeventy-six mothers of children and adolescents aged 6–19 years.ResultsThe mothers identified concepts, causes and community experience of underweight and overweight children and adolescents, however, some gaps and misconceptions were observed. These included perspectives that suggest a limited understanding of the concepts of mild and moderate malnutrition and stunting and citing of ‘witches and wizards’ as causes of malnutrition. The mothers observed that being underweight was more prevalent in rural communities of Osun and Gombe states, while overweight was more prevalent in urban communities in Osun state. The majority of the women reported no known food taboo or restrictions, and no cultural beliefs relating to the nutrition of children and adolescents.ConclusionGaps and misconceptions exist in the perceptions of mothers on underweight and overweight children and adolescents. Food taboos, food restrictions and other cultural beliefs were not reported by majority of the mothers. Educational programmes for mothers on child/adolescent nutrition should target identified gaps and misconceptions.

Background Female Genital Mutilation (FGM) is believed to have a negative effect on sexual and reproductive health but the evidence from nationally representative sample in high-burdened countries like Nigeria is scarce. This study explored the association between FGM and sexual behaviour in a nationally representative sample of Nigerian women. Methods A secondary data analysis was conducted using the Nigeria Demographic Health Survey conducted in 2013 and 2018 among women aged 15–49 years. The descriptive summaries of respondent characteristics by marital status were presented using frequencies and percentages. The proportion and 95% Confidence Interval (CI) of circumcision by sexual behaviour characteristics were computed. A multivariable log-binomial logistic regression was used to determine the association between sexual behaviour and female circumcision while adjusting for other covariates. All analyses were performed using Stata 15.1 (StataCorp, College Station, TX, USA) at the 0.05 level of significance. Results The proportion of circumcised women was 38.6% among those who were ever-married and 32.4% among those unmarried. There were no statistically significant relationship between circumcision status and sexual behaviour among women who were unmarried. However, circumcised women who were ever married had 18% higher risk of having contracted sexually transmitted disease in the last 12 months preceeding the survey and 10% higher risk of engaging in pre-marital sex compared to ever married women who were uncircumcised after adjusting for other covariates. However, the risk of having multiple sexual partners in the last 12 month among uncircumcised ever married women was lower (aRR = 0.80; 95% CI: 0.66–0.97) in the adjusted model. Conclusion Circumcision is not associated with positive sexual behavioural outcomes including delay in sexual debut, virginity and marital fidelity, although there exists some perception behind increasing FGM in Nigeria including prevention of premarital sex and ensuring marital fidelity. While we strongly discourage FGM in all its form, we assert the need for alternative health promoting community measures to address these inherent sexual perceptions toward eliminating FGM and improving sexual and reproductive health across population groups.

Ameloblastoma is a benign but highly infiltrative tumour, a behaviour that is lacking in adenomatoid odontogenic tumour but partly shared by the odontogenic keratocyst which possesses a unique intrinsic growth potential with marked ability for destroying bone and a high tendency recurrence. High frequency of stromal myofibroblasts (assessed with alpha smooth muscle actin (α-SMA) correlates with aggressive behaviour while p53-cell cycle regulation system is critical in odontogenic tumours with immunoreactivity signifying prognostic status. This study aims to determine and compare the immunoreactivity of these selected tumours to p53 and α-SMA in order to establish if a relationship exists between the frequency and pattern of distribution of myofibroblasts and the behaviour of these lesions.69 blocks of ameloblastoma, and 23 each of adenomatoid odontogenic tumor (AOT), and odontogenic keratocyst (OKC/KCOT) were retrieved. Immunohistochemistry technique was applied for evaluation of these two markers staining with primary antibodies to p53 and -SMA and the frequency and pattern of distribution of myofibroblasts and immunoreactivity to p53 analysed and compared using ANOVA. p was set at0.05.Immunoreactivity to p53 and α-SMA was highest in ameloblastoma (solid compared to unicystic) with highest mean positive cells to α-SMA (29.7±20.1) and p53 (28.3±24.5) in plexiform ameloblastoma. This suggests that ameloblastoma was the most aggressive of tumours studied. Different pharmacological agents that can regulate stromal MF are useful aids to decrease the need for radical surgery in extensive and aggressive odontogenic tumours.L’améloblastome est bénin mais untumeur mes infiltratif, un comportement qui fait défaut dans la tumeur odontogénique adénomatoïde mais en partie partagé par le kératocyste odontogène qui possède un potentiel de croissance intrinsèque unique avec une capacité marquée de destructionet une récidive à forte tendance. Haute fréquence de stromalmyofibroblastes (évalués avec de l’actine musculaire alpha lisse (α-SMA) est en corrélation avec un comportement agressif lors de la régulation du cycle des cellules p53 est essentiel dans les tumeurs odontogènes immunoréactives signifiant le statut pronostique. Cette étude vise à déterminer et comparer activité l’immunoré de ces tumeurs sélectionnées à p53 et α-SMA afin d’établir s’il existe une relation entre le fréquence et schéma de distribution des myofibroblastes et de la comportement de ces lésions.69 blocs d’améloblastome, et 23 chacun de tumeur odontogénique adénomatoïde (AOT) et odontogènedes kératocystes (OKC/KCOT) ont été récupérés. Immunohistochimiela technique a été appliquée pour l’évaluation de ces deux marqueurs de coloration avec des anticorps primaires dirigés contre p53 et α-SMA et la fréquence et schéma de distribution des myofibroblastes et de l’immunoréactivité àp53 analysé et comparé à l’aide de l’ANOVA. p a été fixé à0,05.Immuno réactivité à p53 et α-SMA était la plus élevée dans l’améloblastome (solide par rapport α-SMA (29,7±20,1) et p53(28,3±24,5) dans l’améloblastome plexiforme. Cela suggère que L’améloblastome était la tumeur la plus agressive étudiée. Les agents pharmacologiques différentes peuvent réguler la MF stromale sont des aides utiles pour diminuer le besoin de chirurgie radicale en cas de chirurgie étendue et agressive tumeurs odontogènes.Améloblastome, AOT, OKC/KCOT, p53, α-SMA, myofibroblastes, tumeurs odontogènes, immunoréactivité.

Introduction: Hybrid lesions are lesions showing the combined histopathological characteristics of two or more previously recognized odontogenic tumours and /cysts of different categories. Hybrid lesions do exist because of close interrelationship of several odontogenic lesions and also because odontogenic tumors and cysts can arise at any stage of odontogenesis. The objective of this study was to present 2 cases of hybrid odontogenic tumour that is composed of adenomatoid odontogenic tumour (AOT) and ameloblastoma. Case Reports: Case 1: A 33year old female patient with a bucco-lingual swelling in the left mandibular premolar-molar-ramus regions of 13years duration. The lesion measured about 15x5x3cm, it is non tender. Surgical specimen revealed hybrid lesion of granular cell type ameloblastoma and AOT. Case 2: An 18year old female patient with a painless right mandibular molar-ramus swelling of 10years duration. Mandibulectomy specimen measured about 11 cm x 8.5 cm x 5 cm and was found to be hybrid lesion of acanthomatous ameloblastoma and AOT. Conclusion: Both cases had a very long clinical duration and showed more buccal bone expansion with barely noticeable lingual bone expansion. With such clinical scenarios, a suspicion of hybrid tumour should be made.

Objective:This study aimed to identify individual and contextual factors that are associated with under- and over-nutrition among school-aged children and adolescents in two Nigerian states.Design:Community-based cross-sectional study.Setting:The study was carried out in rural and urban communities of Osun and Gombe States in Nigeria.Participants:A total of 1200 school-aged children and adolescents.Results:Multi-level analysis showed that the full models accounted for about 82 % and 39 % of the odds of thinness or overweight/obese across the communities, respectively. Household size (adjusted OR (aOR) 1·10; P = 0·001; 95 % CI (1·04, 1·16)) increased the odds, while the upper wealth index (aOR 0·43; P = 0·016; 95 % CI (0·22, 0·86)) decreased the odds of thinness. Age (aOR 0·86; P < 0·001; 95 % CI (1·26, 8·70)), exclusive breastfeeding (aOR 0·46; P = 0·010; 95 % CI (0·25, 0·83)), physical activity (aOR 0·55; P = 0·001; 95 % CI (0·39, 0·78)) and the upper wealth index (aOR 0·47; P = 0·018; 95 % CI (0·25, 0·88)) were inversely related with overweight/obesity, while residing in Osun State (aOR 3·32; P = 0·015; 95 % CI (1·26, 1·70)), female gender (aOR 1·73; P = 0·015; 95 % CI (1·11, 2·69)) and screen time > 2 h/d (aOR 2·33; P = 0·005; 95 % CI (1·29, 4·19)) were positively associated with overweight/obesity.Conclusions:The study shows that selected community and individual-level factors are strongly associated with thinness and overweight/obesity among school-aged children and adolescents.

Background: Little evidence exists on the relationship between diet-related factors and child/adolescent malnutrition in Nigeria. This study aimed to assess the associations between household food insecurity (HFI), dietary diversity (DD), and dietary patterns (DP) with the double burden of malnutrition (DBM) among 6–19-year-olds in two Nigerian States. Methods: This community-based cross-sectional study was carried out among 1200 respondents (6–19 years in age) in the Gombe and Osun States of Nigeria. HFI was assessed using the HFI access scale. DD was assessed using a 24-h dietary recall. DP were determined by principal component analysis using a 30-day food frequency questionnaire. DP scores were categorized into quartiles (Q) for statistical analysis. Diet-related predictors of DBM were assessed using logistic regression. Results: HFI was experienced by 568 (47.3%) respondents. The median DD score was 7.0 (maximum of 14). Two DPs were identified, diversified DP (DDP) and traditional DP (TDP). TDP was significantly associated with both thinness (Q4:OR: 2.91; 95% CI: 1.52–5.55; Ptrend: 0.002) and overweight/obesity (Q4:OR: 2.50; 95% CI: 1.43–4.35; Ptrend: 0.007), while DDP was inversely related with thinness (Q4:OR: 0.36; 95% CI: 0.21–0.61; Ptrend: 0.008) as compared to Q1. Conclusions: TDP increased the odds for DBM, while the DDP reduced the odds.

Nigeria has faced an increasing number of disasters over the last decade including the outbreaks of infectious diseases, air pollution, natural disasters, communal and ethno-religious crises, and acts of terrorism. While Nigeria’s National Health Policy identifies public health emergency preparedness and response as a major policy thrust, with the goal of reducing the burden of public health emergencies, the 2019 Global Health Security Index shows that Nigeria, with a score of 12.5 out of 100, ranks very low in emergency preparedness and response planning. With the projection that Nigeria will likely experience more disasters in the future, it is important to review her current disaster risk reduction framework with particular reference to the health sector and make suggestions for improving response. The current National Disaster Management Framework provides for a comprehensive multisectoral response and incorporates the health ministry/department at all levels of disaster response; however, it does not appear that the framework is well known or utilized by stakeholders. Furthermore, no specific attention is given to the threat of emerging and re-emerging infectious diseases and the associated public health emergencies. Although, the establishment of the Nigeria Centre for Disease Control has assisted with addressing some of the gaps in this respect, the response at the sub-national level is still sub-optimal as evidenced by the response to the COVID-19 pandemic. Disaster preparedness and response planning is particularly lacking at healthcare facilities and this article provides a practical guide that will assist stakeholders in the design of an organizational disaster preparedness plan.

Background: Double burden of malnutrition (DBM) is the co-existence of overweight/obesity and undernutrition. Rising prevalence rates of childhood overweight/obesity in Nigeria have been reported, whilst undernutrition continues to be prevalent. This study aimed to estimate the prevalence and distribution of underweight, stunting, thinness, overweight/obesity, and DBM among school-aged children and adolescents in two Nigerian States. Methods: This was a community-based cross-sectional study carried out in Osun and Gombe States. A total of 1,200 children aged 6 – 19 years were recruited using multi-stage sampling technique. Weight, height and data on demographic, socio-economic, household/family characteristics of the children were collected using structured interviewer administered questionnaires. Nutritional status was calculated using the WHO 2007 reference values using BMI-for-age (thinness, overweight/obesity), height-for-age (stunting) and weight-for-age (underweight). DBM was described at the population and individual levels. Results: The mean age of the respondents was 11.6 ± 3.8 years. The overall prevalence rate of stunting was 34.9%, underweight was 13.5%, thinness was 10.3% and overweight/obese was 11.4% and 4.0% had individual level DBM, which typifies the DBM at individual and population levels. These rates differed significantly across demographic, socio-economic and household/family characteristics (p < 0.05). Gombe State, which is in the Northern part of Nigeria, had significantly higher burden of stunted, underweight and thin children than Osun State, while Osun State, in the Southern part of Nigeria, had a significantly higher burden of overweight/obesity. Conclusions: The study found evidence of DBM both at population and individual levels. The overall prevalence rates of stunting, underweight, thinness and overweight/obesity in this study were high, and they differed significantly across the demographic, socio-economic and household/family characteristics. There is the need for government and all other stakeholders to design nutritional educational programmes that will target both under- and over-nutrition among older children in the different contexts.

OBJECTIVES: The study investigated the association between intraocular pressure changes and clinical ocular signs in 51 patients with orbitozygomatic complex fractures. Diplopia, chemosis, enophthalmos, subconjunctival haemorrhage, periorbital ecchymosis and extraocular muscles entrapment were assessed. STUDY DESIGN: Intraocular pressure was measured in mmHg at different time intervals with Perkins and Goldman tonometers; within first 3 days of injury (T1), 24 h post-elevation within 3–14 days of injury (T2), 1 month after initial treatment assessment (T3), 2 months after initial treatment assessment (T4), and 3 months after initial treatment assessment (T5). Intraocular pressure changes between T2/T1 and T3/T1 were analysed as change 1 and change 2, respectively, with paired t test. Significance was set at p

BackgroundCompetent and skilled birth attendants are critical in the reduction of maternal and infant morbidity and mortality at delivery. This study aimed to determine the association between knowledge and self-rated confidence in facility birth attendants affiliated with maternal and neonatal health (MNH) interventions.MethodsA descriptive cross-sectional study was conducted in 24 primary healthcare facilities in Osun state, Nigeria among 128 consenting facility birth attendants who were selected via a multi-stage sampling technique. Each attendant received a semi-structured interviewer-administered questionnaire. The dependent variables included the respondent’s level of knowledge in MNH interventions and their self-rated confidence in MNH skills such as the provision of antenatal care service, normal labour, use of a partograph and the management of obstetric complications and post-partum haemorrhage. Bivariate analysis of factors associated with knowledge and self-rated confidence in MNH skills was performed with statistical significance set at p

This research investigated the effects of varying concentrations of crude oil on some physicochemical characteristics of crude oil polluted agricultural soils from Igodan- Lisa, Oba-Ile and Ido-Ani areas of Ondo State, Nigeria. The soil samples were exposed to 1-4% (w/w) crude oil and analyzed monthly for six periods using standard physical and chemical analytical techniques. Results indicated that the physicochemical properties were altered. The physicochemical parameters varied with increase in the amount of crude oil spilled and time. The pH and moisture contents (MC) progressively decreased with increase in concentration of crude oil applied to the samples. Polluted soils had lower pH values (4.91- 6.17) and MC (15.24% to 26.83%) relative to control samples. The organic matter content increased with increased amount of crude oil spilled in the range of 6.65-10.93%. The organic carbon contents progressively increased with concentration of crude oil and sampling days. At 4% crude oil pollution, the organic carbon content in the samples were 6.04-8.28%, 5.39-7.82% and 6.05-8.21% for Igodan-Lisa, Oba-Ile and Ido-Ani soils respectively at 0-180 days of experiment. The changes in soil physicochemical suggested that soil integrity and quality is altered by crude oil contamination. The increased acidity with time also suggested the release of acidic metabolites in bioremediation by intrinsic microorganisms.

This paper presents an epidemiological analysis of the trends in Covid-19 infection in the first 100 days of the pandemic in Nigeria and the response efforts in the country. Data from the Nigerian Centre for Disease Control and other relevant sources were analysed to show the national trend and compare sub-national trends. Analysis revealed that the infection rate is rising in the country despite efforts at lockdown and restriction of movements. Over the 100 days of focus, Nigeria recorded 15,181 cases with a case fatality rate (CFR) of 2.6%. Age 31-40 years had the highest number of cases, while only 8% occurred in individuals over 60 years. All the infections recorded in the first 24 days were in the South-west region. The South-west region had overall highest number of cases (56.7%) but the lowest CFR rate (1.5%), while South South region had the highest CFR (4.8%). CFR ranged from 0% (5 states) to 17% in Anambra State. Lagos, Federal Capital Territory (FCT) and Kano – the main hubs of international travel into Nigeria – were the epicentres of the infection and recorded 60% of all cases. Three-fifths of the confirmed cases (60%) were concentrated in 20 Local Government Areas (LGA), comprising 2.6% of the country’s 774 LGAs. Nigeria is performing exceptionally low number of tests (

Background The persistently high prevalence of girl-child marriage remains a public health and developmental concern in Nigeria. Despite global campaign against the practice and policy efforts by Nigerian government, the prevalence remains unabated. This study investigates the prevalence and the influence of ethnicity and religious affiliation on the girl-child marriage among female adolescents in Nigeria. Methods Data of 7804 girls aged 15–19 years extracted from the 2013 Nigeria Demographic and Health Survey were used. Ethnic groups were classified into five: major Northern ethnic group (Hausa/Fulani); Northern ethnic minorities; two major Southern ethnic groups (Yoruba and Igbo), and Southern ethnic minorities. The prevalence of girl-child marriage was determined for the five ethnic groups and individually for each ethnic minority group. Relationships between ethnicity and religious affiliation on girl-child marriage were explored using Cox proportional hazard regression models, adjusting for residence, education and wealth quintile. Results Child marriage was higher for the Northern majority ethnic group of Hausa/Fulani (54.8%) compared to the two major Southern ethnic groups (3.0–3.6%) and aggregated Northern ethnic minorities (25.7%) and Southern minorities (5.9%). However, overall, the less known Northern ethnic minority groups of Kambari (74.9%) and Fulfude (73.8%) recorded the highest prevalence. Compared to the major Southern ethnic group of Yoruba, the adjusted hazard ratio (AHR) of child marriage was significantly higher for Northern ethnic minorities (AHR = 2.50; 95% C.I. = 1.59–3.95) and Northern major ethnicity (AHR = 3.67, 95% C.I. = 2.33–5.77). No significant difference was recorded among Southern ethnic groups. Girls affiliated to other religions (Muslim and traditionalist) had higher child-marriage risks compared to Christians (AHR = 2.10; 95% C.I. = 1.54–2.86). Conclusion Ethnicity and religion have independent associations with girl-child marriage in Nigeria; interventions must address culturally-laden social norms that vary by ethnic groups as well as religious-related beliefs.

SummaryBackground The maternal mortality ratio in Nigeria is estimated to be about 814 per 100,000 live births, and deliveries taken outside a health facility have been implicated as a major factor for this high number. Mobile phones interventions are continually being explored in the health field but its usefulness in maternal health in Nigeria has not been widely explored. Objective To determine the impact of SMS (text messages) on maternal health behaviour in Ife-Ijesa zone of Osun State, Nigeria. Methods We conducted an experimental study involving 2 groups of pregnant women and sent text messages to both groups. The control group was sent general health messages while the intervention group was sent specific pregnancy related messages and both groups were followed up till 6 weeks after delivery. Results An increase in facility delivery rates among both groups, between the index pregnancy and their last pregnancies, were recorded for both groups with a higher percentage increase recorded in the intervention group (29%) compared with the control group 13%. Crude and adjusted linear regression coefficients were done to estimate the effect of the intervention on the change in proportion of deliveries in health facilities. After adjusting for other variables, the difference obtained was a significant value of 14% (regression coefficient = 0.14, 95% CI = 0.08–0.20, P value = .005). Most participants in the intervention group (96.6%) expressed support for the use of text message for maternal health promotion. Conclusion The SMS-based intervention has a positive effect on facility delivery, and mothers welcome its use in pregnancy.

Background The aim of the study was to identify the proportion of female sex workers, men who have sex with men, and people who inject drugs who had accessed HIV prevention services at public health facilities and peer-led facilities, their level of satisfaction with these services, and perceived barriers and challenges to accessing HIV services from public and peer-led HIV prevention service providers. Methods A mixed-method approach was used to collect data from key populations in the four states in Nigeria. Quantitative data collected included level of satisfaction with and barriers to use of public and peer-led facilities. In-depth interviews and focus-group discussions were conducted to explore reasons for satisfaction with and barriers to use of services. Descriptive and bivariate analyses were was conducted for quantitative data. Qualitative data were summaried, emerging themes identified, described and quotes reflecting the themes corresponding to interview questions highlighted. Results Nine hundred sixty-seven persons responded to questions on the use of public health or/and peer-led facilities. Two hundred thirty-eight (49.4%) respondents had received HIV and sexual and reproductive health services through public health facilities, and 236 (48.7%) had received the services through peer-led facilities. Significantly more respondents were satisfied with the quality of services provided by peer-led organisations than with public health facilities with respect to service providers listening to respondent’s problems and concerns (p = 0.007),privacy and confidentiality (p = 0.04) and respect of rights of service recipients (p = 0.04). Significantly more respondents using peer-led organisations than those using public health facilities identified no barriers to service access (p = 0.003). More respondents using public health facilities than peer-led facilities identified cost of services (p = 0.01), confidentiality (p = 0.002), waiting time (p p = 0.001) as barriers to service access. Thee was no difference in the proportion of respondents willing to discontinue their use of either facilities (p = 0.08). Qualitative data revealed that concerns with access of services at the public health facility were due mainly to stigma and the effects of the same-sex prohibition law. Conclusion Key populations were more satisfied receiving HIV prevention services at peer-led organisations than at public health facilities.

Background Orofacial malignancy is a growing health issue common in developing regions of the world. Presentation patterns are myriad with geographic variations. Advanced stage owing to late presentation constitutes a significant public health burden. The site and type of the lesions are valuable in diagnosis and patient management. Aim This study aims to review cases of primary orofacial malignancies at the OAUTHC Dental Hospital. Objectives The objective of the study was to determine the prevalence of histologically diagnosed orofacial malignancies, the relative frequencies, types and site of distribution. Materials and methods Records of patients with orofacial malignancies at the OAUTHC, Dental Hospital over a period of 10 years (January 2008-December 2017) were reviewed, demographic data (age, gender and site), history of tobacco use were retrieved and entered into a pro forma. The data obtained were analysed with STATA 11. Statistical significance was set at P Results Of 375, 109 cases of neoplasms seen were primary malignant tumours, with prevalence rate of 29.1%. There were 71 (65.1%) males and 38 (34.9%) females (male:female ratio of 1.87:1), mean age (48.7 ± 19.3 years) and range (4-94 years). Affected sites were mandible (41, 37.6%), maxilla (39, 35.8%), palate (17, 15.6%) and others. Lesions were mainly squamous cell carcinomas (SCC: 46, 42.2%), salivary gland adenocarcinomas (SGAs, 25, 22.9%) including 8 (32%) cases of adenoid cystic carcinoma (ACC). Others were odontogenic carcinoma (18, 16.5%) and lymphoma (8, 7.3%). Most specimen analysed were hard tissues (n = 63, 57.8%). Thirty-four (73.9%) cases of SCC and 66 (60.6%) cases of primary malignancies were in the 5th-9th decades of life. This was statistically significant at P = 0.000. Conclusion SCC was more prevalent than salivary and odontogenic carcinomas. ACC and mucoepidermoid carcinoma were two most common SGAs. Metastatic tumours to the jaws are rare.

The current generation of adolescents is the largest ever, with 1.2 billion people aged 10-19 years worldwide. They are at risk of inheriting a world blighted by climate change and scarred by covid-19. Although they have been spared the most severe direct effects of the pandemic, the indirect effects on their wellbeing are devastating.12 Many adolescents are experiencing disruptions to their access to health, education, and preventive services, and the pandemic has further exacerbated inequalities.1 The pandemic is changing everything for adolescents and youth, as they experience the transitions that will define their future wellbeing: completing education, moving into the workforce, and forming life partnerships. Even before covid-19, adolescents and young adults faced multiple and intersecting challenges to their wellbeing. These challenges include social injustice and inequalities (such as those related to gender, gender identity, and inclusion), insufficient social protection, inadequate mental health, poor sexual and reproductive health, and an inability to exercise their rights resulting in unintended pregnancies, HIV, and all forms of malnutrition. Adolescents and young adults are also experiencing a crisis of connection to family, community, and society, with increasing …

Summary Background Young people's health has emerged as a neglected yet pressing issue in global development. Changing patterns of young people's health have the potential to undermine future population health as well as global economic development unless timely and effective strategies are put into place. We report the past, present, and anticipated burden of disease in young people aged 10–24 years from 1990 to 2013 using data on mortality, disability, injuries, and health risk factors. Methods The Global Burden of Disease Study 2013 (GBD 2013) includes annual assessments for 188 countries from 1990 to 2013, covering 306 diseases and injuries, 1233 sequelae, and 79 risk factors. We used the comparative risk assessment approach to assess how much of the burden of disease reported in a given year can be attributed to past exposure to a risk. We estimated attributable burden by comparing observed health outcomes with those that would have been observed if an alternative or counterfactual level of exposure had occurred in the past. We applied the same method to previous years to allow comparisons from 1990 to 2013. We cross-tabulated the quantiles of disability-adjusted life-years (DALYs) by quintiles of DALYs annual increase from 1990 to 2013 to show rates of DALYs increase by burden. We used the GBD 2013 hierarchy of causes that organises 306 diseases and injuries into four levels of classification. Level one distinguishes three broad categories: first, communicable, maternal, neonatal, and nutritional disorders; second, non-communicable diseases; and third, injuries. Level two has 21 mutually exclusive and collectively exhaustive categories, level three has 163 categories, and level four has 254 categories. Findings The leading causes of death in 2013 for young people aged 10–14 years were HIV/AIDS, road injuries, and drowning (25·2%), whereas transport injuries were the leading cause of death for ages 15–19 years (14·2%) and 20–24 years (15·6%). Maternal disorders were the highest cause of death for young women aged 20–24 years (17·1%) and the fourth highest for girls aged 15–19 years (11·5%) in 2013. Unsafe sex as a risk factor for DALYs increased from the 13th rank to the second for both sexes aged 15–19 years from 1990 to 2013. Alcohol misuse was the highest risk factor for DALYs (7·0% overall, 10·5% for males, and 2·7% for females) for young people aged 20–24 years, whereas drug use accounted for 2·7% (3·3% for males and 2·0% for females). The contribution of risk factors varied between and within countries. For example, for ages 20–24 years, drug use was highest in Qatar and accounted for 4·9% of DALYs, followed by 4·8% in the United Arab Emirates, whereas alcohol use was highest in Russia and accounted for 21·4%, followed by 21·0% in Belarus. Alcohol accounted for 9·0% (ranging from 4·2% in Hong Kong to 11·3% in Shandong) in China and 11·6% (ranging from 10·1% in Aguascalientes to 14·9% in Chihuahua) of DALYs in Mexico for young people aged 20–24 years. Alcohol and drug use in those aged 10–24 years had an annual rate of change of >1·0% from 1990 to 2013 and accounted for more than 3·1% of DALYs. Interpretation Our findings call for increased efforts to improve health and reduce the burden of disease and risks for diseases in later life in young people. Moreover, because of the large variations between countries in risks and burden, a global approach to improve health during this important period of life will fail unless the particularities of each country are taken into account. Finally, our results call for a strategy to overcome the financial and technical barriers to adequately capture young people's health risk factors and their determinants in health information systems.

Unprecedented global forces are shaping the health and wellbeing of the largest generation of 10 to 24 year olds in human history. Population mobility, global communications, economic development, and the sustainability of ecosystems are setting the future course for this generation and, in turn, humankind. At the same time, we have come to new understandings of adolescence as a critical phase in life for achieving human potential. Adolescence is characterised by dynamic brain development in which the interaction with the social environment shapes the capabilities an individual takes forward into adult life.3 During adolescence, an individual acquires the physical, cognitive, emotional, social, and economic resources that are the foundation for later life health and wellbeing. These same resources define trajectories into the next generation. Investments in adolescent health and wellbeing bring benefits today, for decades to come, and for the next generation. Better childhood health and nutrition, extensions to education, delays in family formation, and new technologies offer the possibility of this being the healthiest generation of adolescents ever. But these are also the ages when new and different health problems related to the onset of sexual activity, emotional control, and behaviour typically emerge. Global trends include those promoting unhealthy lifestyles and commodities, the crisis of youth unemployment, less family stability, environmental degradation, armed conflict, and mass migration, all of which pose major threats to adolescent health and wellbeing. Adolescents and young adults have until recently been overlooked in global health and social policy, one reason why they have had fewer health gains with economic development than other age groups. The UN Secretary-General's Global Strategy for Women's, Children's and Adolescents' Health initiated, in September, 2015, presents an outstanding opportunity for investment in adolescent health and wellbeing. However, because of limits to resources and technical capacities at both the national and the global level, effective response has many challenges. The question of where to make the most effective investments is now pressing for the international development community. This Commission outlines the opportunities and challenges for investment at both country and global levels (panel 1).

ObjectivesThis study aimed to assess the safety and effectiveness of self-managed misoprostol abortions obtained outside of the formal health system in Lagos State, Nigeria.DesignThis was a prospective cohort study among women using misoprostol-containing medications purchased from drug sellers. Three telephone-administered surveys were conducted over 1 month.SettingData were collected in 2018 in six local government areas in Lagos State.ParticipantsDrug sellers attempted to recruit all women who purchased misoprostol-containing medication. To remain in the study, participants had to be female and aged 18–49, and had to have purchased the medication for the purpose of abortion. Of 501 women initially recruited, 446 were eligible for the full study, and 394 completed all three surveys.Primary and secondary outcome measuresUsing self-reported measures, we assessed the quality of information provided by drug sellers; the prevalence of potential complications; and the proportion with completed abortions.ResultsAlthough drug sellers provided inadequate information about the pills, 94% of the sample reported a complete abortion without surgical intervention about 1 month after taking the medication. Assuming a conservative scenario where all individuals lost to follow-up had failed terminations, the completion rate dropped to 87%. While 86 women reported physical symptoms suggestive of complications, only six of them reported wanting or needing health facility care and four subsequently obtained care.ConclusionsDrug sellers are an important source of medical abortion in this setting. Despite the limitations of self-report, many women appear to have effectively self-administered misoprostol. Additional research is needed to expand the evidence on the safety and effectiveness of self-use of misoprostol for abortion in restrictive settings, and to inform approaches that support the health and well-being of people who use this method of abortion.

To determine the sleep pattern among Nigerian school-attending adolescents and its association with socioenvironmental factors and the use of electronic devices.Descriptive cross-sectional survey.Public and private secondary schools in Ile-Ife, Osun State, Nigeria.Multistage sampling technique was used to select 346 school-attending adolescents aged 10-19 years.A modified version of the Adolescent Sleep Habits Survey Questionnaire was administered to respondents in the school setting using the facilitated self-administration method.Participants' mean age was 13.5±2.29 years, and the male-female ratio was 1:1.1. The mean total sleep duration on weekends of 9 hours (h) 08 minutes (min) ± 113 min was significantly higher than that of weekdays (7 h 15 min ± 86 min) (P.001). About half of the respondents (48.7 %) had access to a computer. Majority of the respondents (80.9%) use one or more electronic device at bedtime, although cell phone was used by more than half (52.3%) of the respondents at bedtime. The proportion of adolescents with short sleep duration was 44.4% for weekdays and 5.5% for weekends. Lower social class and non-use of computers in the night time were independent predictors of adequate sleep duration on weekdays, whereas female sex, age (early adolescence), and polygamous family setting were independent predictors of sufficient sleep on weekends.A high proportion of school-attending adolescents have insufficient sleep on weekdays and significantly sleep less during weekdays compared to weekends. There is a need to target adolescents, parents, and school authorities with education on sleep issues.

Many low- and middle-income countries do not yet have policies to implement effective oral health programs. A reason is lack of human and financial resources. Gaps between resource needs and available health funding are widening. By building capacity, countries aim to improve oral health through actions by oral health care personnel and oral health care organizations and their communities. Capacity building involves achieving measurable and sustainable results in training, research, and provision of care. Actions include advancement of knowledge, attitudes and skills, expansion of support, and development of cohesiveness and partnerships. The aim of this critical review is to review existing knowledge and identify gaps and variations between and within different income levels in relation to the capacity building and financing oral health in the African and Middle East region (AMER). A second aim is to formulate research priorities and outline a research agenda for capacity building and financing to improve oral health and reduce oral health inequalities in the AMER. The article focuses on capacity building for oral health and oral health financing in the AMER of the IADR. In many communities in the AMER, there are clear and widening gaps between the dental needs and the existing capacity to meet these needs in terms of financial and human resources. Concerted efforts are required to improve access to oral health care through appropriate financing mechanisms, innovative health insurance schemes, and donor support and move toward universal oral health care coverage to reduce social inequality in the region. It is necessary to build capacity and incentivize the workforce to render evidence-based services as well as accessing funds to conduct research on equity and social determinants of oral health while promoting community engagement and a multidisciplinary approach.

Considering the huge resources -- human and materials -- that are involved in intervention programs the findings in this supplement points to the need to pay greater attention to the quality of program design implementation and evaluation. This is crucial to ensuring that the huge investments made in adolescent and young people’s sexual health interventions in LMICs truly count. On the one hand greater emphasis on the use of evidence-informed approaches and designs underpinned by sound theoretical framework is clearly important. The results of the reviews published in this supplement aptly add to the available evidences on interventions that are effective in addressing specific young people’s SRH challenges in LMICs. On the other hand the case needs to be made strongly for the inclusion of rigorous evaluation approaches in every intervention program to enhance the potential for generating good evidence as well as facilitate opportunities to derive useful lessons for future interventions -- from both successful and nonsuccessful programs alike. Thus on the whole there is the need to ensure that interventions addressing adolescents and young people’s health issues are well grounded scientifically in terms of their design and complemented with effective implementation and rigorous evaluation and the successful projects taken to scale -- only then would the investments in adolescent and young people’s SRH interventions in LMICs truly count.

PURPOSE: To assess Serum Prealbumin in the severity of illness and monitor response to treatment in odontogenic space infection. PATIENTS AND METHODS: This was a prospective cohort study comprising patients being managed for odontogenic space infection at the Obafemi Awolowo University Teaching Hospital, Ile-Ife, Nigeria. The calculated sample size was 69. Clinical parameters (Swelling Size, Visual Analogue Scale for pain intensity, and Maximal Interincisal Distance) were measured on day 0, day 4, and day 8. Other clinical parameters were Number of Anatomic Spaces Involved, setting of treatment, and Length of Hospital Stay. Serum Prealbumin levels were also serially measured. The relationship between Serum Prealbumin level and the clinical parameters was established using Spearman’s correlation test, independent t test, Friedman’s test, and linear regression. Significance level was set at .05. RESULTS: The mean Serum Prealbumin level at presentation (day 0) was 19.19 ± 4.61 mg/dl, which was significantly lower among inpatients (p = 0.001). On days 0, 4, and 8, Serum Prealbumin negatively correlated with Number of Anatomic Spaces Involved (p

This analysis is based on data from the Global Early Adolescent Study, which aims to understand the factors that predispose young people aged 10-14 years to positive or negative health trajectories. Specifically, interview transcripts from 202 adolescents and 191 parents across six diverse urban sites (Baltimore, Ghent, Nairobi, Ile Ife, Assuit and Shanghai) were analysed to compare the perceived risks associated with entering adolescence and how these risks differed by gender. Findings reveal that in all sites except Ghent, both young people and their parents perceived that girls face greater risks related to their sexual and reproductive health, and because of their sexual development, were perceived to require more protection. In contrast, when boys grow up, they and their parents recognised that their independence broadened, and parents felt that boys were strong enough to protect themselves. This has negative consequences as well, as boys were perceived to be more prone to risks associated with street violence and peer pressure. These differences in perceptions of vulnerability and related mobility are markers of a gender system that separates young women and men's roles, responsibilities and behaviours in ways that widen gender power imbalance with lifelong social and health consequences for people of both sexes.

Objective To determine preferences for companionship during labor and to identify associated factors. Methods The present prospective cross-sectional survey was conducted at a university teaching hospital in Nigeria between September 1, 2011, and February 28, 2012. Participants included women who underwent the first stage of labor and delivery at the facility, male partners, and healthcare workers from the maternity unit. Data were collected using a pretested questionnaire. Results There were 226 parturients, 158 male partners, and 69 healthcare workers included in the final analysis; in all, 50 (22.1%) parturients and 37 (23.4%) male partners approved of companionship during labor, whereas 62 (90%) healthcare workers supported it. Among those who approved, a parturient's male partner was stated to be the preferred companion by 33 (66%) parturients, 32 (86%) male partners, and 58 (94%) healthcare workers. The perception of conduciveness of the labor ward for companionship was associated with approving of companionship among both the parturients (adjusted odds ratio [aOR] 2.74) and male partners (aOR 15.79). Previous home delivery (aOR 31.43) and companionship during a previous delivery (aOR 23.00) were also associated with approval. Conclusion Most couples had negative attitudes toward companionship during labor. Intensive education programs and restructuring of facilities could enable Nigerian labor wards to improve the delivery experience for both parturients and their male partners.

Summary Background West Africa has the highest proportion of married adolescents, and the highest adolescent childbirth rate and maternal death rate in sub-Saharan Africa. However, few studies have focused on the type and quality of health care accessed by pregnant young women in countries in this subregion. Methods We obtained data from Demographic and Health Surveys done between 2010 and 2014, to compare the use, timing, source, and components of antenatal care between adolescent and older first-time mothers in 13 west African countries. The sample included primiparous women who were aged 15–49 years with a livebirth in the 5-year survey recall period, and women were assigned to one of three groups on the basis of age at the time of childbirth: adolescent (10–19 years), young adults (20–24 years), or adults (25 years or older). We calculated the percentage of women who: attended at least one antenatal care visit, completed at least one visit during the first trimester of pregnancy, attended four or more appointments in antenatal care, and received four components of antenatal care (blood pressure measurement, urine tests, blood tests, and information on complications), as well as the sector where the women received care. We primarily report the comparison between adolescents and young adults. Findings In 2016, we acquired data from the Demographic Health Surveys from 13 west African countries between 2010 and 2014 on primiparous women. The study sample was 19 211 women, of whom 10 025 (52%) were adolescents, 6099 (32%) were young adults, and 3087 (16%) were adults. Overall, 17 386 (91%) of 19 211 first-time mothers made use of antenatal care facilities on at least one occasion. 3597 (41%) of 8741 adolescents compared with 8202 (47%) of all 17 386 women began the use of antenatal care during the first trimester. Across west Africa, 5430 (62%) of 8741 adolescents had four or more antenatal care visits compared with 4067 (71%) of 5717 young adults and 2358 (81%) of 2928 adults. Of those who had four or more visits to antenatal care, 2779 (51%) of 5430 adolescents received all the antenatal care components examined compared with 2488 (61%) of 4067 young adults and 1600 (68%) of 2358 adults. Although most women received antenatal care in the public sector, in nine of the 13 countries, the proportion of women that used the private sector was higher in older mothers. Interpretation Although a large percentage of west African adolescents use some antenatal care for their first birth, they seek care later, make fewer visits during pregnancy, and receive fewer components of care than older first-time mothers. Governments must ensure the pregnancy care accessed by adolescent mothers is of high quality and tailored to meet their needs. Funding MSD for Mothers.

Introduction : Medical and dental students are a high-risk group for hepatitis B virus (HBV) infection which is an occupational hazard for them and a leading cause of death globally. Prevention strategies include vaccination and observance of standard precaution. However, available reports claim utilization of the prevention strategies is low. This study evaluated the attitude of the students towards HBV vaccine and cross-infection practices. Methods : This study was a cross-sectional study carried out at the College of Health Sciences, Obafemi Awolowo University, Nigeria. Using the convenience sampling method, anonymous self-administered questionnaires were distributed to the first 120 participants that volunteered to participate in the study. Data analysis was done using IBM's Statistical Package (SPSS) version 20 software. Statistical level of significance was set at p < 0.05. Results : Over eighty percent (83.2%) of the participants had at least a dose of the HBV vaccine while 79.65% completed the three doses. Majority (94.7%) of the students that did not receive the vaccine cited their busy schedule as the reason for their failure to be vaccinated. Taking every patient as a contagious disease risk (86.5%), washing hands after contact with patients' body fluids (82.1%) and wearing gloves before touching mucous membranes and non-intact skin (74.1%) were the most practiced universal standard precaution items. Conclusion : The uptake rate of HBV vaccination and practice of standard precaution among the students are commendable. However, there is need for improvement considering the level of HBV infection in Nigeria. Key words : Medical and dental students, hepatitis B vaccine, universal precaution, Nigeria

Most tumours of the maxillary sinus are "silent" producing no direct symptoms until they reach advanced stage. Treatment of these tumours often includes maxillectomy, with outcomes that vary depending on several factors. To highlight the clinical pattern of patients that had Maxillectomy for sinonasal tumours and the challenges of management in a Nigerian tertiary Hospital. Records were obtained from a chart review of all patients who underwent Maxillectomy for sinonasal tumour over a 10 year period. During the period, 31 patients with maxillary tumour were seen and only 11 patients underwent different forms of Maxillectomy. Three (27%) were males and 8 (73%) were females. Only four patients could afford a computed tomography scan. The common complications were postoperative epistaxis and feeding difficulty (27%) while cheek graft failure (9%) and depression (9%) were least. The challenges encountered in our facility during management include limited diagnostic equipments and treatment facilities and the fact that patients could not afford the cost of management. The challenges in the management are enormous and need to be addressed to enhance early presentation, diagnosis and better management and outcome.

There is increasing interest in the need to address the ethical dilemmas related to the engagement of adolescents in sexual and reproductive health (SRH) research. Research projects, including those that address issues related to STIs and HIV, adverse pregnancy outcomes, violence, and mental health, must be designed and implemented to address the needs of adolescents. Decisions on when an individual has adequate capacity to give consent for research most commonly use age as a surrogate rather than directly assessing capacity to understand the issues and make an informed decision on whether to participate in research or not. There is a perception that adolescents participating in research are more likely to be coerced and may therefore not fully comprehend the risk they may be taking when engaging in research. This paper examines the various ethical issues that may impact stakeholders' decision making when considering engaging adolescents in SRH research in Nigeria. It makes a case for lowering the age of consent for adolescents. While some experts believe it is possible to extrapolate relevant information from adult research, studies on ethical aspects of adolescents' participation in research are still needed, especially in the field of sexual and reproductive health where there are often differences in knowledge, attitudes and practices compared to adults. The particular challenges of applying the fundamental principles of research ethics to adolescent research, especially research about sex and sexuality, will only become clear if more studies are conducted.

In this paper, we describe the potential role laypersons on ethics committees can play in ensuring community concerns are addressed in the design and implementation of genomic research. We draw inferences from the outcome of an empirical study of the impact of training of laypersons to address community engagement issues in ethics review of research protocol. While this paper does not advocate a particular solution, it describes the importance of community engagement in genomic research, the current limitations there are in engaging communities in the design of these research projects and how communities can be indirectly engaged in the design and implementation of genomic research through the engagement of laypersons on ethics committees. However, to ensure that these laypersons can play this role, their capacity needs to be built to play this role appropriately. There is evidence to show that where resources are invested in building the capacity of laypersons to play their role as community ‘watchdogs’ in research, they play this role aptly. Community engagement is important in genomic research as genomic researchers will increasingly require community perspectives in critical ethics decision making.

Purpose This qualitative study assesses the cross-cultural and intergenerational reactions of young adolescents and parents to puberty in Ile-Ife, Nigeria, and Nairobi, Kenya. Methods Sixty-six boys and girls (aged 11–13 years) and their parents participated in narrative interviews conducted in English or local languages in two urban poor settings in Ile-Ife and Nairobi. All interviews were recorded, transcribed, translated, and uploaded into Atlas.ti software for coding and analysis. Results Reactions of parents and adolescents to puberty were similar across both sites, with few exceptions. Adolescents' reactions to bodily changes varied from anxiety to pride. Adolescents generally tend to desire greater privacy; trying to hide their developing bodies from others. Most female adolescents emphasized breast development as compared with menstruation as the mark for pubertal initiation, while males emphasized voice changes. Among some ethnic groups in Nairobi, parents and adolescents view male circumcision as the hallmark of adolescence. Parents in both sites reported that with pubertal changes, adolescents tend to become arrogant and engaged in sexual relationships. Parents' reported responses to puberty include: educating adolescents on bodily changes; counseling on sexual relationships; and, provision of sanitary towels to females. Parents' responses are generally focused more on daughters. Approaches used by mothers in educating adolescents varied from the provision of factual information to fear/scare tactics. Compared with their own generation, parents perceive that their own children achieve pubertal development earlier, receive more puberty-related education from mothers, and are more exposed to and influenced by media and information technologies. Conclusions Adolescents' responses to their pubertal bodily changes include anxiety, shame, and pride. Adolescents desire greater privacy. Parents' reactions were broadly supportive of their children's pubertal transition, but mothers' communication approaches may sometimes be inappropriate in terms of using fear/scare tactics.

Background: Globally, young people account for 15.5% of the total global disability-adjusted life-years burden for all age groups. They face mental health, nutritional problems, accidental and intentional injuries, sexual and reproductive health problems, and substance abuse. These health challenges have effects on their oral health. This paper discusses the oral health problems adolescents face and suggests approaches for providing integrated oral and general health care for adolescents. Discussion: Oral health issues linked with adolescent health concerns include: malocclusion and esthetic concerns linked with mental health status; oral and maxillofacial injuries linked with accidental and intentional injuries; oral manifestations of sexually transmitted infections; oral leukoplakia and oral cancers linked with alcohol, tobacco and psychoactive substance abuse; and oral manifestations of anemia resulting from nutritional problems. Training oral health care providers on adolescent health and care could promote prompt diagnosis, management and prevention of complications associated with major health challenges affecting adolescents. Conclusion: Adolescent oral health care needs focused attention: as a possible route for early diagnosis and management of general health problems and for promoting adolescent oral health care. Oral health care should be integrated into adolescent friendly services and oral health care providers should learn how to handle adolescents’ health needs.

Background: Non-communicable diseases (NCDs) have become the leading cause of deaths globally and the key associated risk factors – alcohol abuse, physical inactivity, cigarette smoking and poor dietary patterns – are often initiated in adolescence. Co-existence of these risk factors further increase the risk for NCDs. Yet, very little is known about the pattern of co-occurrence of behavioural risk factors for NCDs among Nigerian adolescents, especially those in rural areas. This study aimed to assess the prevalence and determinants of clustering patterns of behavioural risk factors for NCDs among in-school adolescents in rural areas of Osun State, Nigeria. Methods: This cross-sectional study involved 476 adolescents recruited through multi-stage sampling across Osun State. Data were collected through a facilitated self-administered questionnaire with questions adapted from the Global School-Based Health Survey (GSHS) instrument. Data were analysed using Stata, with binary logistic regression used to identify determinants. Results: The mean age of the respondents was 14.7±2.0 years and females constituted 50.2% of them. Among the respondents, 36.1% had reported consuming alcoholic drinks but no one met the criteria for harmful alcohol use, while 8.8% had ever smoked cigarettes and only one respondent (0.2%) was a current smoker. The prevalence of poor diet (89.5%) and physical inactivity (85.9%) was, however, high. Poor diet and physical inactivity co-occurred in 369 (77.5%) respondents, while one respondent (0.2%) had three risk factors (poor diet, physical inactivity and current smoking). Being in a senior secondary school class (odds ratio, OR=1.6; 95% confidence interval, C.I.=1.04–2.39) and living with parents (OR=0.53; 0.33–0.90) were significantly associated with clustering of NCD behavioural risk factors. Conclusion: The prevalence of clustering of modifiable risk factors for NCDs was high among rural-based in-school adolescents in south-west Nigeria, and there is a need to mount effective interventions. Findings from this study have the potential to inform effective school-based NCD control programmes.

Background: Substance use is a leading adolescent health problem globally, but little is known regarding associated factors for adolescent substance use in Nigeria. This study compared the prevalence of substance use among in-school adolescents in urban and rural areas of Osun State, Nigeria, and identified risk and protective factors. Methods: This cross-sectional study involved 600 randomly selected adolescents (aged 10–19 years) from rural and urban areas of Osun State, Nigeria. Data were collected using the facilitated self-completed questionnaire method. Binary logistic regression was used to examine the association of individual, peer, and parental factors with adolescent substance use. Adjusted odds ratio (OR) and 95% confidence interval (CI) were obtained. Results: About two-thirds of respondents had used substances in both rural (65.7%) and urban areas (66.0%) (p=0.93). Logistic analysis showed private school attendance as a risk factor for substance use (OR=2.32, 95% CI=1.20–4.46) and adolescent disapproval of adult substance use as a protective factor (OR=0.47, 95% CI=0.27–0.82) in rural areas. For urban areas, having friends who use substances (OR=4.04, 95% CI=1.39–11.6) and a mother having had tertiary education (OR=3.34, 95% CI=1.06–10.4) were risk factors while parental disapproval of substance use (OR=0.50, 95% CI=0.28–0.90) was a protective factor. Conclusion: Lifetime prevalence of substances is high among in-school adolescents in Osun State. The risk and protective factors for adolescent substance use somewhat differ for rural and urban areas, and these have implications for designing effective intervention strategies.

Aim: The aim of this study was to evaluate the efficacy of adjunctive rectal misoprostol compared to oxytocin infusion in the prevention of primary postpartum hemorrhage after routine active management of the third stage of labor in women with identifiable risk factors for uterine atony. Material and Methods: A double-blind randomized controlled trial was carried out at Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria. A total of 264 parturients with known risk factors for postpartum hemorrhage were randomized to receive either rectal misoprostol (600 µg; n = 132) or oxytocin infusion (20 IU in 500 mL; n = 132) after routine active management of the third stage of labor. Intrapartum blood loss was measured using a combination of the BRASSS-V calibrated drapes and differential pad weighing. Hematocrit was measured intrapartum and 24 h postpartum. Results: There was no significant difference (P = 0.07) in the mean intrapartum blood loss between the misoprostol (387.28 ± 203.09 mL) and oxytocin (386.73 ± 298.51 mL) groups. There was also no difference in the requirement for additional intervention for uterine atony (P = 0.74). Postpartum hematocrit drop and blood transfusion were, however, significantly less in the misoprostol group. Conclusion: Rectal misoprostol is as effective as oxytocin infusion as an adjunct for prevention of postpartum hemorrhage in women with risk factors for uterine atony and is associated with a lower hematocrit drop and blood transfusion postpartum. However, shivering, pyrexia and vomiting are more frequent with misoprostol, though usually self-limited.
