Acceptability of an Orange-Flavoured Zinc Sulphate Dispersible Tablet in the Management of Acute Diarrhoea in Under-five Children in Lagos, Nigeria.

BACKGROUND: Acute diarrhoea is a significant cause of morbidity and mortality in children under five, especially in subSaharan Africa. The WHO recommends using oral rehydration solution (ORS) and zinc therapy for its management, but the metallic taste of zinc often hinders adherence. METHOD: This prospective open-label intervention study took place at three health facilities in Lagos, Southwest Nigeria, involving children aged 3 to 59 months with acute diarrhoea. Sociodemographic and diarrhoea-related data were obtained. Palatability was assessed using a 5-point hedonic scale, and adherence was determined by the proportion of prescribed zinc sulfate tablets consumed. Caregivers received a 10-day supply of the study drug and ORS sachets for each child, along with participant diaries for tracking drug intake, palatability scores, and adverse events. Follow-up was conducted on Days 3 and 7, and diaries were collected between Days 10 and 14. RESULTS: Out of the 294 participants, most caregivers were mothers (86.0%), had at least a secondary education (88.1%), and were employed (70.7%). The majority of children were male (54.2%), and under 18 months old (52.2%). The average palatability score was 2.65 (±0.78), with no significant differences based on age or gender. Mean adherence was 93.03%, with 89.3% achieving ≥80% adherence, and adherence did not significantly differ by age or gender. The only reported adverse event, vomiting, decreased from 18.8% on Day 1 to 0.5% on Day 10. CONCLUSION: The study indicates that the orange-flavored dispersible zinc sulfate tablet is well-accepted by children aged 3 to 59 months with acute diarrhoea in Lagos, Nigeria.

CONTEXTE: La diarrhée aiguë est une cause significative de morbidité et de mortalité chez les enfants de moins de cinq ans, en particulier en Afrique subsaharienne. L'OMS recommande l'utilisation de la solution de réhydratation orale (SRO) et de la thérapie au zinc pour sa prise en charge, mais le goût métallique du zinc entrave souvent l'observance. MÉTHODE: L'étude d'intervention prospective à ciel ouvert a eu lieu dans trois établissements de santé à Lagos, dans le sud-ouest du Nigeria, impliquant des enfants de 3 à 59 mois souffrant de diarrhée aiguë. Des données sociodémographiques et liées à la diarrhée ont été obtenues. La palatabilité a été évaluée à l'aide d'une échelle hédonique à 5 points, et l'observance a été déterminée par la proportion de comprimés de sulfate de zinc prescrits consommés. Les aidants ont reçu une provision de 10 jours du médicament de l'étude et des sachets de SRO pour chaque enfant, ainsi que des journaux de suivi pour noter la prise du médicament, les scores de palatabilité et les événements indésirables. Un suivi a été effectué aux jours 3 et 7, et les journaux ont été collectés entre les jours 10 et 14. RÉSULTATS: Sur les 294 participants, la plupart des aidants étaient des mères (86,0%), avaient au moins une éducation secondaire (88,1%), et étaient employées (70,7%). La majorité des enfants étaient de sexe masculin (54,2%) et avaient moins de 18 mois (52,2%). La note moyenne de palatabilité était de 2,65 (±0,78), sans différences significatives en fonction de l'âge ou du sexe. L'observance moyenne était de 93,03%, avec 89,3% atteignant une observance ≥ 80%, et l'observance ne différait pas de manière significative en fonction de l'âge ou du sexe. Le seul événement indésirable signalé, les vomissements, est passé de 18,8% le jour 1 à 0,5% le jour 10. CONCLUSION: L'étude indique que le comprimé de sulfate de zinc dispersible à l'arôme d'orange est bien accepté par les enfants de 3 à 59 mois souffrant de diarrhée aiguë à Lagos, au Nigeria.

Preliminary Study on Open Labelled Randomized Controlled Trial of the Safety and Efficacy of Hydroxychloroquine and Chloroquine Phosphate for the Treatment of Persons Infected with 2019 Coronavirus Disease in Nigeria.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a causative agent of COVID-19 is a leading cause of ill-health and deaths worldwide. Currently, COVID-19 has no known widely approved therapeutics. Thus, the need for effective treatment. OBJECTIVES: We investigated the safety and efficacy of two (2) therapeutic agents; chloroquine phosphate (CQ), 2- hydroxychloroquine (HCQ) and a control (standard supportive therapy) among hospitalized adults with COVID-19. METHODS: The clinical trial was done in accordance to the World Health Organization master protocol for investigational therapeutics for COVID-19. Atotal of 40 participants with laboratory-confirmed positive COVID-19 were enrolled. Blood samples and oropharyngeal (OP) swabs were obtained on days 1,3,15 and 29 for safety and efficacy assessments. RESULTS: The baseline demographics showed that the median ages in years (range) were 45 (31-57) in CQ, 45 (36.5-60.5) in HCQ, 43 (39.5-67.0) and 44.5 (25.3-51.3) in the control (P<0.042).At randomization, seven (7) participants were asymptomatic, thirty-three (33) had mild symptoms, eight (8) had moderate symptoms while three (3) had severe symptoms. The average day of conversion to negative COVID-19 was 15.5 days for CQ, 16 days for HCQ and 18 days for the control(P=0.036). CONCLUSION: The safety assessment revealed no adverse effect of the drugs in COVID-19 patients after treatment. These findings proved that chloroquine and hydroxychloroquine are effective for the treatment of COVID-19 among hospitalized adults. It also confirmed that they are safe.

Effect of Perioperative Tranexamic Acid on Blood Loss following Open Simple Prostatectomy: A Prospective Review in Nigerian Men.

BACKGROUND: Haemorrhage is a common complication following open simple prostatectomy and patients may sometimes require a blood transfusion. Tranexamic acid has been shown to reduce blood loss following transurethral resection of the prostate and open radical prostatectomy. This study evaluated the effect of perioperative intravenous administration of tranexamic acid on blood loss and blood transfusion rates in patients who had OSP for benign prostatic enlargement. METHODOLOGY: This was a comparative study of patients with documented prostate glands 60g and above scheduled for OSP. Initial hematocrit was done a day before surgery. The patients were randomized into a tranexamic acid group, which received perioperative intravenous tranexamic acid and the no-TXA group which received placebo (0.9% saline). All patients had open simple retropubic prostatectomy. Final post-operative hematocrit was assessed 72 hours after surgery, and blood loss was calculated using the modified Gross formula (actual blood loss = estimated blood volume x change in hematocrit / mean hematocrit). The transfusion rate was documented. RESULTS: Fifty-six patients participated in this study and were randomized into a tranexamic acid group and no-tranexamic acid group. The mean age of patients in the tranexamic acid group was 66.07 ±7.08 years and was comparable to the no- tranexamic acid group which was 66.50 ± 8.80 years (P = 0.842). The median total blood loss was lower in the tranexamic acid group (502mls, IQR 613) compared to the no-tranexamic acid group (801mls, IQR 1069). The difference in the median blood loss between the two groups was 299mls (U 275, P 0.055). The rate of blood transfusion was lower in the tranexamic acid group (6 patients, 21%) compared to the no tranexamic acid group (11 patients, 39%), (P = 0.146). There was no difference in complication rates between the two groups. CONCLUSION: The use of tranexamic acid in patients undergoing open simple prostatectomy showed a trend towards reduced intraoperative blood loss and less need no tranexamic for blood transfusion. This is of clinical significance, especially in elderly patients with low cardiovascular reserve.

CONTEXTE: L'hémorragie est une complication courante après une prostatectomie simple ouverte et les patients doivent parfois recevoir une transfusion sanguine. Il a été démontré que l'acide tranexamique réduit la perte de sang après une résection transurétrale de la prostate et une prostatectomie radicale ouverte. Cette étude a évalué l'effet de l'administration intraveineuse périopératoire d'acide tranexamique sur les pertes sanguines et les taux de transfusion sanguine chez des patients ayant subi une PSO pour hypertrophie bénigne de la prostate. MÉTHODOLOGIE: Il s'agissait d'une étude comparative de patients dont la prostate de 60 g et plus était documentée et qui devaient subir une PSO. L'hématocrite de base a été effectué un jour avant la chirurgie. Les patients ont été répartis aléatoirement dans le groupe acide tranexamique, qui a reçu de l'acide tranexamique periopératoire par voie intraveineuse, et dans le groupe sans TXA, qui a reçu un placebo. Tous les patients ont subi une prostatectomie rétropubienne simple ouverte. L'hématocrite postopératoire a été évalué, et la perte de sang calculée à l'aide de la formule de Gross modifiée. Le taux de transfusion a été documenté. RÉSULTATS: Cinquante-six patients ont participé à cette étude et ont été randomisés entre le groupe avec acide tranexamique et le groupe sans acide tranexamique. L'âge moyen des patients du groupe acide tranexamique était de 66,07 ±7,08 ans et était comparable à celui du groupe sans acide tranexamique qui était de 66,50 ± 8,80 ans (P =0,842). La perte sanguine totale médiane était plus faible dans le groupe avec acide tranexamique (502 ml, IQR 613) que dans le groupe sans acide tranexamique (801 ml, IQR 1069). La différence de la perte de sang médiane entre les deux groupes était de 299 ml (U 275, P 0,055). Le taux de transfusion sanguine était inférieur dans le groupe acide tranexamique (6 patients, 21%) par rapport au groupe sans acide tranexamique (11 patients, 39%), (P =0,146). Il n'y avait pas de différence dans les taux de complication entre les deux groupes. CONCLUSION: L'utilisation de l'acide tranexamique chez les patients subissant une prostatectomie simple ouverte a montré une tendance à la réduction de la perte de sang peropératoire et un besoin moindre de transfusion sanguine.

Intimate Partner Violence and Risk Factors among Women during the COVID-19 Movement Restriction in Nigeria: An Online Survey.

BACKGROUND: The rapid spread of the SARS-CoV-2 infection in the absence of treatment or the presence of vaccines is forcing nations to respond with strong preventive measures ranging from mitigation, containment, and in extreme cases, quarantines. While these measures are a useful measure of infection control, they can lead to significant social, economic, and psychological consequences. This study sought to establish the prevalence and risk factors of intimate partner violence during the COVID-19 movement restriction in Nigeria among girls and women. METHODS: An online-based questionnaire survey using Google Forms was conducted over four weeks among girls and women aged 15 years and above. Data analysis was performed using SPSS version 20, and logistic regression was used to determine risk factors for IPV experience during the lockdown. RESULTS: Overall, 32.8% of respondents reported ever experiencing IPV, and 42.5% experienced IPV during the lockdown. Verbal (35.1%) and psychological (24.1%) violence were the commonest forms of violence in the study. There was considerable overlap between the various forms of IPV in the study. Age less than 35 years (aOR = 1.3; CI = 1.2 - 1.4), resident in the northeast region (aOR=1.6; CI=1.41.9), alcohol (aOR=1.3;CI=1.2-1.5) and substance (aOR = 1.5; CI = 1.3 - 1.8) use, average family monthly income < $100 (aOR = 1.4;CI=1.2 - 1.5), daily or weekly income (aOR = 2.7; CI = 2.5-3.1) had an increased association with IPV during the lockdown, residency in the southeast region had lower odds of experiencing IPV (aOR=.0.5; CI = 0.3-0.8). CONCLUSION: The reported lockdown prevalence of IPV was 42.8%, with verbal and psychological violence being the most prevalent form of IPV. Age less than 35 years, resident in northeast and southeast, use of alcohol or substances, average family monthly income < $100, and partner being a daily-weekly earner was associated with IPV experience. Policymakers in the future should consider the consequences, including IPV, before issuing such an order.

CONTEXTE: La propagation rapide de l'infection par le CoV-2 du SRAS en l'absence de traitement ou présence de vaccins oblige les nations à réagir par des mesures préventives fortes allant de l'atténuation à l'endiguement et, dans les cas extrêmes, à la mise en quarantaine. Bien que ces mesures soient utiles pour contrôler l'infection, elles peuvent avoir des conséquences sociales, économiques et psychologiques importantes. Cette étude visait à établir la prévalence et les facteurs de risque de la violence exercée par le partenaire intime au cours de la restriction de mouvement du COVID-19 au Nigeria, chez les filles et les femmes. MÉTHODES: Une enquête par questionnaire en ligne utilisant google form a été menée pendant quatre semaines auprès de filles et de femmes âgées de 15 ans et plus. L'analyse des données a été réalisée à l'aide de la version 20 de SPSS et une régression logistique a été utilisée pour déterminer les facteurs de risque de violence conjugale pendant la période de restriction. RÉSULTATS: Dans l'ensemble, 32,8 % des personnes interrogées ont déclaré avoir déjà subi des VPI, et 42,5 % ont subi des VPI pendant l'enfermement. La violence verbale (35,1 %) et la violence psychologique (24,1 %) étaient les formes de violence les plus courantes dans l'étude. Il y avait un chevauchement considérable entre les différentes formes de VPI dans l'étude. L'âge inférieur à 35 ans (aOR=1,3 ; CI= 1,2 - 1,4), la résidence dans la région nord-est (aOR=1,6; CI=1,4-1,9), la consommation d'alcool (aOR=1,3; CI=1,2 - 1,5) et de substances (aOR=1,5 ; CI = 1,3 - 1,8), le revenu mensuel moyen de la famille < 100 $ (aOR=1. 4 ; IC = 1,2 - 1,5), le revenu quotidien ou hebdomadaire (aOR = 2,7 ; IC = 2,5-3,1) était davantage associé à la VPI pendant le lockdown, la résidence dans la région du sud-est avait moins de chances d'être victime de VPI (aOR = 0,0,5 ; IC = 0,3-0,8). CONCLUSION: La prévalence de la VPI pendant le lockdown était de 42,8 %, la violence verbale et psychologique étant la forme de VPI la plus répandue. L'âge inférieur à 35 and, le fait de résider dans le nord-est et le sud-est, la consommation d'alcool ou de substances, le revenu mensuel moyen de la famille inférieur à 100 dollars et le fait que le partenaire gagne sa vie toutes les semaines étaient associés à l'expérience de la VPI. À l'avenir, les décideurs politiques devraient prendre en compte les conséquences, y compris la VPI, avant d'émettre un tel ordre.

Impact of SARS-CoV-2 Pandemic on Antiretroviral Access at a Large Treatment Centre in Lagos, Nigeria.

INTRODUCTION: The SARS-CoV-2 pandemic has ravaged the world with significant implications on the socio-economic and health status of individuals. Several measures were put in place to curtail the pandemic especially movement restrictions. The effect of this pandemic and the restriction measures could further compound the health needs of PLWHA. This study thus described the trend in access to HIV/AIDS care services before and during the COVID-19 induced lockdown and the possible consequences on their treatment outcome. METHODS: A secondary analysis of client data was carried out at the HIV clinic of the Nigerian Institute of Medical Research. The sociodemographic and clinical data [type of ART, duration on ART, clinical services 3-months before and during the COVID-19 induced Lockdown] were extracted from the electronic medical records. Data obtained was analyzed using the SPSS version 22.0. RESULTS: The median age of PLWHA was 45 years (IQR: 39-51), with the predominant age group being 25-49 years (65.4%). The majority were females (68.7%), married (59.5%), had at least secondary education (82.8%), and employed (81.5%). The median duration on ART was 102 months (IQR: 67-138) with the majority on non-Protease Inhibitor based regimen (77.7%). In the 3 months before the lockdown, there was an increase in drug pick-up of approximately 25% over the booked appointment compared to a decline of 40% when the lockdown was enacted. CONCLUSION: The significant decline in drug pick-up during the SARS-CoV-2 pandemic raises the need for measures to ensure continued access to drugs and care among PLWHA.

INTRODUCTION: La pandémie de SRAS-CoV-2 a ravagé le monde avec des implications significatives sur l'état socio- économique et sanitaire. Plusieurs mesures ont été mises en place pour freiner la pandémie, en particulier la restriction des déplacements. L'effet de cette pandémie et les mesures de restriction pourraient encore aggraver les besoins de santé des PVVIH. Cette étude décrit ainsi la tendance des services de soins du VIH / SIDA avant et pendant le verrouillage induit par le COVID-19 et les conséquences possibles sur l'issue de leur traitement. MÉTHODES: Une étude transversale parmi les PVVIH fréquentant la clinique VIH de l'Institut nigérian de recherche médicale. Les données sociodémographiques et cliniques [type de TAR, durée de la TAR, services cliniques 3 mois avant et pendant le verrouillage induit par COVID-19] ont été extraites des dossiers médicaux électroniques. Les données obtenues ont été analysées à l'aide de la version 22.0 de SPSS. RÉSULTATS: L'âge médian des PVVIH était de 45 ans (IQR (39-51), le groupe d'âge prédominant étant 25-49 ans (65,4%). La majorité étaient des femmes (68,7%), mariées (59,5%), avaient au moins secondaire (82,8%) et employé (81,5%). La durée médiane des TAR était de 102 mois (IQR: 67-138), la majorité sous traitement sans inhibiteur de protéase (77,7%). Au cours des 3 mois précédant le verrouillage , il y a eu une augmentation de la cueillette de médicaments d'environ 25% par rapport au rendez-vous réservé, comparativement à une baisse de 40% lorsque le verrouillage a été décrété. CONCLUSION: La baisse significative de la collecte de médicaments pendant la pandémie de SRAS-CoV-2 fait ressortir la nécessité de prendre des mesures pour assurer un accès continu aux médicaments et aux soins parmi les PVVIH.

Barriers and solutions to effective mentorship in health research and training institutions in Nigeria: Mentors, mentees, and organizational perspectives.

Aims and Background: Mentoring relationships and programs have become a subject of global interest and their relevance is high in the ever-evolving health system. In Nigeria, informal system of mentoring is largely practiced. To be able to institutionalize mentoring program, there is need to explore the various challenges of mentoring process and suggest potential approaches for effective mentor-mentee relationship in health research institutions in Nigeria. Subjects and Methods: The study was designed to explore the barriers and solutions to mentoring process from the perspectives of the mentor, mentee, and organization in health research and training institutions in Nigeria. A cross-sectional descriptive design was employed and the study was conducted among 21 health researchers drawn from 24 health research institutions across the 6 regions of Nigeria. The nominal group technique was adopted in the data collection process. Results: The most frequently reported mentor challenges were "lack of understanding of mentorship process" (84.2%) and "lack of capacity for mentoring" (78.9%), while those of mentee were "mentor preference" (73.7%) and "lack of freedom of expression" (47.4%). "Culture of selfishness/individualism" (84.2%) and "lack of formal relationship" (63.2%) were the most mentioned systemic challenges. Training on mentoring process and relationship was mentioned as the most frequent approach to overcoming challenges for the three perspectives. Conclusion: Significant mentorship challenges exist in the Nigerian health, academic and research institution. Systematic approaches to finding and implementing the appropriate solutions are needed to circumvent these bottlenecks.

Challenges of Accessing Care in Art Clinic during COVID-19 Lockdown in Lagos.

BACKGROUND: As the SARS-CoV-2 pandemic continues to ravage the world, its impact on the health systems and survival of people with chronic diseases especially People living with HIV [PLWH] could be undermined. It becomes relevant to assess the challenges PLWH face during this period to institute measures towards combating the negative effects of the pandemic. AIMS: This study aims to investigate the challenges faced by PLWH in accessing care during the lockdown period in Lagos, Nigeria. The study was a cross-sectional one involving PLWH aged 18 years and above who presented for care. An interviewer-administered questionnaire was used to obtain information on demographic characteristics, their knowledge about COVID-19 disease, and challenges experienced in accessing care during the COVID-19-induced lockdown. Ethical approval was obtained from the Institution Research Ethics Board (IRB) of NIMR. PATIENTS AND METHODS: Data generated from the survey was exported to Excel and analyzed using SPSS version 23.0. RESULTS: The mean age of PLWH who participated in the study was 42.2 (±12.2) years. The majority were female (74.3%), married (66.3%), employed (58.9%), and on less than $100 monthly income (80.5%). The commonest challenges experienced were psychological (78.5%), financial (68%) and food (40.7%). There were significant association among the income status, lack of food (OR: 2.5, CI: 1.4-4.5, P = 0.002), financial challenges (OR: 1.7, CI: 1.0-3.0, P = 0.048) and psychological challenges (OR; 1.8, CI: 1.0-3.5, P = 0.05). Ninety-five percent of participants believed SARS-COV-2 infection is a viral infection. CONCLUSIONS: PLWH faces a myriad of challenges that would have a significant impact on their overall well-being and the gains of HIV care.

Simple Prostatectomy for Giant Benign Prostatic Hyperplasia in Sub-Saharan Africa: Case Series and Literature Review.

INTRODUCTION: Benign prostatic hyperplasia (BPH) is a common cause of bladder outlet obstruction in men worldwide. African men are known to have larger mean prostate volumes than other races. Giant benign prostatic hyperplasia (GBPH) is defined as prostate size greater than 200 grams. Management of GBPH is associated with several challenges which have been under-reported from the African sub-region. OBJECTIVE: To highlight the peculiarities of clinical presentation, surgical management and outcome of GBPH. PATIENTS AND METHODS: Men with BPH and trans-rectal ultrasound estimated prostate volume > 200 grams who were scheduled for open simple prostatectomy between January and December 2016 in our hospital were prospectively studied. RESULTS: Four patients with GBPH had simple prostatectomy during the period under review. Their ages ranged from 68 to 78 years with a mean age of 73.7 years.Three patients (75.0%) had transvesical prostatectomy while one (25.0%) had retropubic prostatectomy. The enucleated prostate specimen were found to weigh 312.1g, 396.4g, 420.8g and 450.0g respectively with mean weight of 394.8 ±50.2g and mean operation time of 111.7 ±19.7 minutes. They all had blood transfusion post-operatively with mean transfusion of 3±1.5 pints of blood per patient with relatively longer hospital stay (mean 10 days). CONCLUSION: The surgical management of GBPH can be quite challenging. Recalcitrant gross haematuria, chronic urinary retention and renal impairment are possible modes of presentation. Open simple prostatectomy is the best option for treatment in our environment. It is associated with improved quality of life and minimal morbidity in expert hands.

INTRODUCTION: L'hyperplasie bénigne de la prostate (HBP) est une cause fréquente d'obstruction de la vessie chez les hommes du monde entier. Les hommes africains sont connus pour avoir des volumes de prostate moyens plus importants que les autres races. L'hyperplasie bénigne géante de la prostate (GBPH) est définie comme une taille de la prostate supérieure à 200 grammes. La gestion du GBPH est associée à plusieurs défis qui ont été sous-déclarés dans la sous-région africaine. OBJECTIF: Mettre en évidence les particularités de la présentation clinique, de la prise en charge chirurgicale et du résultat de la GBPH. PATIENTS ET MÉTHODES: Les hommes atteints d'HBP et d'une échographie trans-rectale d'un volume prostatique estimé> 200 grammes qui devaient subir une prostatectomie simple ouverte entre janvier et décembre 2016 dans notre hôpital ont été étudiés de manière prospective. RÉSULTATS: Quatre patients atteints de GBPH ont eu une prostatectomie simple au cours de la période sous revue. Leur âge variait de 68 à 78 ans avec un âge moyen de 73,7 ans). Trois patients (75,0%) ont eu une prostatectomie transvésicale et un (25,0%) une prostatectomie rétropubienne. L'échantillon de prostate énucléé pesait respectivement 312,1 g, 396,4 g, 420,8 g et 450,0 g avec un poids moyen de 394,8 ± 50,2 g et une durée opératoire moyenne de 111,7 ±19,7 minutes. Ils ont tous eu une transfusion sanguine postopératoire avec une transfusion moyenne de 3 ± 1,5 pintes de sang par patient avec un séjour à l'hôpital relativement plus long (10 jours en moyenne). CONCLUSION: La prise en charge chirurgicale de la GBPH peut être assez difficile. Une hématurie macroscopique récalcitrante, une rétention urinaire chronique et une insuffisance rénale sont des modes de présentation possibles. La prostatectomie simple ouverte est la meilleure option de traitement dans notre environnement. Elle est associée à une meilleure qualité de vie et à une morbidité minimale entre des mains expertes. MOTS CLÉS: Hyperplasie bénigne géante de la prostate, prostatectomie simple, Afrique subsaharienne.

Plasma L-Arginine in Sickle Cell Anaemia Patients in Crises and its Correlation with Markers of Severity of Disease.

INTRODUCTION/OBJECTIVES: Sickle Cell Anaemia (SCA) is a chronic haemolytic and inflammatory disorder characterized by repeated vaso-occlusive (VOC) and hyperhaemolytic crises (HC). These crises determine the quality of life of SCA patients. This study estimated the plasma L-arginine levels in SCApatients during crises (HC and VOC), and correlated these levels with the markers of inflammation in the patients. METHODS: A cross-sectional study comprising of 120 consenting adults (60 SCA patients and 60 HbAA controls). The SCA were grouped as SCA patients in VOC or SCA patients in HC and HbAA controls. All SCA patients presented at the emergency room or the daycare unit of Haematology Department, University College Hospital, Ibadan, Nigeria. Blood samples were collected and haematological parameters and plasma L-arginine levels were determined. RESULTS: There were 30 SCA patients in VOC, 30 SCA patients in HC, and 60 HbAA controls with age ranging from 18 to 58years. The controls had a higher haematocrit than the SCA patients (HbAA>SCA VOC> SCA HC, p<0.001) in each pair wise analysis. The VOC and the HC groups had higher mean White Blood Cell (WBC), platelet count, Absolute Neutrophil Count (ANC), Absolute Lymphocyte Count (ALC), Absolute Monocyte Count (AMC), and reticulocytes count than the HbAA controls. Similarly, the HC group had higher mean WBC, platelet count,ANC,ALC,AMC, and reticulocytes count, and a lower mean percentage irreversible sickle cell than the VOC group. The mean plasma L-arginine was significantly higher in the HbAA control group than those of SCA patients in crises (HbAA controls>SCAVOC>SCAHC, p < 0.001), and higher in the SCAVOC group than in the HC group. There was no significant correlation between plasma L-arginine levels, reticulocyte count, markers of VOC severity and markers of inflammations. CONCLUSION: The plasma L-arginine levels of SCA patients in VOC and HC were lower than those of the HbAA controls. The degree of reduction was however marked in patients in hyperhaemolytic crisis. There was no significant association between the plasma L-arginine levels and the markers of inflammation in the studied patients. The findings in this study buttress the need for consideration of L-arginine supplementation in patients with SCA, especially during acute hemolytic crises.

INTRODUCTION / OBJECTIFS: La SCA est un mal hémolytique et inflammatoire chronique caractérisé par des crises vaso-occlusives (COV) et hyperhémolytiques (HC) répétées, qui déterminent la qualité de vie des patients atteints de SCA. L'étude a estimé les taux plasmatiques de L-arginine chez les patients atteints de SCA pendant les crises (HC et COV), et a mis en corrélation ces taux avec les marqueurs de l'inflammation chez les patients. MÉTHODES: Une étude transversale comprenant 120 adultes consentants (60 patients SCA et 60 contrôles HbAA) regroupés en patients SCA en COV; Patients SCA à HC (tous les patients SCA présentés à la salle d'urgence ou à l'unité de garde du département d'hématologie, University College Hospital, Ibadan, Nigéria); et contrôles HbAA. Des échantillons de sang ont été prélevés et les paramètres hématologiques et les taux de L-arginine ont été déterminés. RÉSULTATS: Il y avait 30 patients SCA en COV, 30 patients SCA en HC et 60 contrôles HbAA avec un âge allant de 18 à 58 ans. Les témoins avaient un hématocrite plus élevé que les patients SCA (HbAA> SCA VOC> SCAHC, p <0,001) dans chaque analyse par paire. Les groupes VOC et HC avaient des taux moyens de globules blancs, de plaquettes, d'ANC, d'ALC, d'AMC et de réticulocytes plus élevés que les témoins HbAA. De même, le groupe HC avait un nombre moyen de globules blancs, de plaquettes, d'ANC, d'ALC, d'AMC et de réticulocytes plus élevés, et un pourcentage moyen de de drépanocytose irréversible plus faible que le groupe COV. La L-arginine plasmatique moyenne était significativement plus élevée dans le groupe témoin HbAA que chez les patients SCA en crise (contrôles HbAA> SCA VOC> SCA HC, p <0,001), et plus élevée dans le groupe SCA VOC que dans le groupe HC, p <0,001. Il n'y avait pas de corrélation significative entre les taux de L-arginine, le nombre de réticulocytes, les marqueurs de gravité des COV et les marqueurs d'inflammations. CONCLUSION: Les taux plasmatiques de L-arginine chez les patients SCAen COV et HC étaient inférieurs à ceux des contrôles HbAA, et le degré de réduction est cependant marqué chez les patients en crise hyperhémolytique. Il n'y avait pas d'association significative entre les taux plasmatiques de L-arginine et les marqueurs de l'inflammation chez les patients étudiés. Les résultats de cette étude renforcent la nécessité d'envisager une supplémentation en L-arginine chez les patients atteints de SCA, en particulier pendant les crises hémolytiques aiguës. MOTS CLÉS: anémie falciforme, L-arginine, crise vaso-oclussive, crise hyperhémolytique.

Determinants of Antimicrobial Use for Covid-19 Related Symptoms among Nigerians.

BACKGROUND: Antimicrobial use plays a key role in development and spread of antimicrobial resistance. Following the global coronavirus disease 2019 (COVID-19) pandemic and the report of the first confirmed case in Nigeria, several states embarked on either a full or partial lockdown as a measure to prevent or curtail the spread of the virus with its attendant challenges. This survey was designed to provide a snapshot of public antimicrobial use and common perception related to antimicrobial use for COVID-19 related symptoms among Nigerian populace. METHODS: We developed and tested a 29-question electronic questionnaire with Google forms asking respondents about their antimicrobial use and perceptions regarding appropriate antimicrobial use for real or perceived symptoms during the outbreak period. Respondents aged 18 years and above were recruited through crowd sourcing and they received the link to the survey tool through emails and social media including WhatsApp, Twitter, Facebook, LinkedIn, and Instagram. All data analysis was performed using SPSS version 26.0. RESULTS: A total of 410 responses were received from the six geopolitical zones in Nigeria comprising 200 (48.8%) females and 210 (51.2%) males. Majority (62.9%) of the respondents had taken antimicrobials in the 3 months period preceding the survey, while less than half (46.8%) received prescription for it. Previous intake of antimicrobial for similar illness was a predictor of antimicrobial intake (OR: 0.55, 95%CI: 0.30-1.01). The most consumed antimicrobial was antimalarial drugs, specifically Artemisinin-based combination therapy (43.4%), followed by antibiotics [Ciprofloxacin (20.2%)]. CONCLUSION: There was high levels of antimicrobial use for COVID-19 related symptoms by the Nigerian public. This is likely to escalate the already high prevalence of antimicrobial use previously reported and may further fuel the emergence of antimicrobial resistance.

CONTEXTE: L'utilisation d'antimicrobiens joue un rôle clé dans le développement et la propagation de la résistance aux antimicrobiens. À la suite de la pandémie mondiale de coronavirus 2019 (COVID-19) et du rapport du premier cas confirmé au Nigéria, plusieurs États se sont engagés dans un verrouillage complet ou partiel en tant que mesure pour prévenir ou freiner la propagation du virus avec ses défis associés. Cette enquête a été conçue pour fournir un aperçu de l'utilisation publique des antimicrobiens et de la perception commune liée à l'utilisation des antimicrobiens pour les symptômes liés au COVID-19 parmi la population nigériane. MÉTHODES: Nous avons développé et testé un questionnaire électronique de 29 questions avec des formulaires Google interrogeant les répondants sur leur utilisation d'antimicrobiens et leurs perceptions concernant l'utilisation appropriée d'antimicrobiens pour les symptômes réels ou perçus pendant la période d'épidémie. Les répondants âgés de 18 ans et plus ont été recrutés via le crowdsourcing et ils ont reçu le lien vers l'outil d'enquête via des e-mails et des médias sociaux, notamment WhatsApp, Twitter, Facebook, LinkedIn et Instagram. Toutes les analyses de données ont été effectuées à l'aide de la version 26.0 de SPSS. RÉSULTATS: Un total de 410 réponses ont été reçues des six zones géopolitiques du Nigéria comprenant 200 (48,8%) femmes et 210 (51,2%) hommes. La majorité (62,9%) des répondants avaient pris des antimicrobiens au cours des 3 mois précédant l'enquête, tandis que moins de la moitié (46,8%) en avaient reçu une prescription. La prise antérieure d'antimicrobiens pour une maladie similaire était un prédicteur de l'ingestion d'antimicrobiens (OR: 0,55, IC à 95%: 0,30-1,01). L'antimicrobien le plus consommé était les antipaludiques, en particulier les associations thérapeutiques à base d'artémisinine (43,4%), suivis des antibiotiques [Ciprofloxacine (20,2%)]. CONCLUSION: Il y avait des niveaux élevés d'utilisation d'antimicrobiens pour les symptômes liés au COVID-19 par le public nigérian. Cela est susceptible d'augmenter la prévalence déjà élevée de l'utilisation d'antimicrobiens rapportée précédemment et peut encore alimenter l'émergence de la résistance aux antimicrobiens.

Prevalence and Clinical Characteristics of Coronavirus Disease 2019 Seen at a Testing Centre in Lagos Nigeria.

BACKGROUND: The SARS-CoV-2 infection continues to ravage the global community since it was declared a pandemic. The socio-demographic and clinical characteristics defining the disease are mainly from Europe and Asia. The disease symptomatology is similar to the prevalent diseases in our environment, this could result in the delay in prompt identification and appropriate management of suspected cases toward combating community transmission. This study evaluates the prevalence, socio-demographic and clinical characteristics of positive cases of COVID -19. METHODS: This was a retrospective cohort study. Data on the socio-demographic, clinical characteristics and the results of the SARS-CoV-2 test of participants at the Nigerian Institute of Medical Research [NIMR] Modified Drive-through Centre for COVID-19 test sample collection over two months [24th February 2020- 27th April 2020] were retrieved from the electronic medical records (EMR). Data obtained were analyzed using SPSS version 22.0. RESULTS: A total number of 481 clients were evaluated in this review. The prevalence of SARS-CoV-2 infection in the population was 14.6%. The mean age of the positive cases was 42.2 [±15.9] years. The common symptoms reported by the positive cases were fever (40.0%), cough (32.9%), sore throat (17.1%) and running nose (15.7%). Fever depicted statistical significance with positive cases with the majority being of mild to moderate clinical severity. CONCLUSION: The prevalence of SARS-CoV-2 infection among this cohort was 14.6% with a male preponderance. Fever and sore throat were the variables that predicted SARS CoV-2 infection among our cohort.

HISTOMORPHOLOGICAL PATTERN OF UROLOGIC MALIGNANCIES IN ILE-IFE, SOUTH-WESTERN NIGERIA.

INTRODUCTION: The last decade witnessed a remarkable rise in the prevalence of several malignant diseases in Nigeria. Whether Urologic malignancies (UM) have followed the same trend remains to be studied. The pattern of UM diagnosed in a Nigerian tertiary hospital is hereby presented. Our aim was to determine the pattern and prevalence of histologically diagnosed UM in Obafemi Awolowo University Teaching Hospitals Complex. Ile-Ife, Nigeria. MATERIALS AND METHODS: A 10-year retrospective review of all patients diagnosed with UM was carried out between January 2005 and December 2014. Data was obtained from the patients' case files and the Ife-Ijesha Cancer registry. Information obtained included demographic characteristics, site of origin and histology. Data was analysed with Statistical package for Social sciences (SPSS) Version 20. RESULTS: A total of 4675 malignancies were histologically confirmed during the study period. UM accounted for 420 (8.9%) of total malignancies. Prostate cancer was the commonest UM with 315 (75%) cases. Others include renal tumours 62(14.8%), bladder tumours 29 (6.9%), testicular tumours 13(3.1%) and scrotal tumour 1(0.2%). UM were commoner in males (348, 88.8%) than females (47, 11.2%) and accounted for 13.8% and 2.18% of all tumours in males and females respectively. CONCLUSION: This study revealed a rising prevalence of UM most especially Prostate and Renal Cancers among other malignancies in Ile-Ife.

Nutrient stability in mould-infested feed and mitigating effect of dietary supplemental vitamins in brown laying hens.

A 10-week study was conducted to assess the impact of mould infestation on nutrient stability of feed and the mitigating effect of supplemental tocopherol, retinol or a multivitamin on performance and hepatic histology of ISA Brown laying chickens. Two batches of corn were obtained: the aflasafe corn used in preparing control diet and corn with physical evidence of mould used in preparing diets 2 to 5 containing no supplemental vitamin, tocopherol, retinol or a branded multivitamin supplementations respectively. One hundred and fifty (150) laying chickens used were completely randomized into five dietary treatments with three replicates of 10 birds each. Results showed that there was gross instability in the nutrients of mouldy maize. The activities of the fungi depleted both protein and lipid contents by 11.54% and 12.72% respectively while crude fibre content rose by 31.7%. There was substantial drop in both retinol and tocopherol while aflatoxin content rose to 267 µg in mouldy corn and 118 µg in the mouldy diets. Feed intake was significantly (P < 0.05) reduced and consequently depressed (P < 0.05) egg production and feed efficiency. Egg quality differs (P < 0.05) in shell thickness and yolk colour. Proliferation of biliary duct epithelium, hepatic degeneration, cellular infiltration, hyper-cellularity or dilation of the sinusoidal spaces characterized livers of birds on mouldy corn diets while supplementation with vitamins subverted mycosis and aflatoxicosis as evidenced by normal-to-mild congestion of hepatocytes. It was concluded that mould contamination in feed compromised feed nutritive values, reduced bird performance and adversely impaired the liver of the experimental birds while tocopherol, retinol or a multivitamin supplementation relapses the damaging potential of mould and mycotoxin differently.

Screening of newly-diagnosed adults with tuberculosis for diabetes mellitus and Impaired Glucose Tolerance in a Local Government Area in Ogun State, Nigeria

Background: Emerging patterns in epidemiological transitions have led to increased risk for Non-Communicable Diseases and infectious conditions globally. Diabetes mellitus (DM) in a population is one such risk factor that could lead to the development of Tuberculosis (TB) due to weakened immune functions in affected persons, with implications for mortality. If not diagnosed early, DM also leads to poor treatment outcomes in TB. Objective: To assess the prevalence of DM and impaired glucose tolerance (pre-diabetes) among newly diagnosed tuberculosis cases in Ijebu-Ode Local Government Area of Ogun State, Nigeria. Methods: This cross-sectional study was conducted among 100 newly diagnosed Pulmonary TB patients in ljebu-Ode LGA. The patients were selected from four health facilities and were screened for elevated Fasting Blood Glucose levels using a laboratory spectrophotometer (glucose oxidase method). Results: The mean age of the 100 study participants was 33 years (± 9.82), with ages within 19 -62 years. Eleven (11.0%) had elevated blood glucose levels suggestive of DM, while 20 (20.0%) had impaired fasting blood glucose levels. Among these 31 patients, 18 (58.0%) were males while 13 (42.0%) were females. The modal ages were within 20-39 years. Conclusion: Screening for DM by healthcare providers should be routinely conducted before commencing TB patients on treatment. This will aid early detection, improve treatment outcomes of TB and prevent mortality among patients with these co-morbidities

SCROTAL SQUAMOUS CELL CARCINOMA AND ASSOCIATED BLINDNESS: A CASE REPORT AND LITERATURE REVIEW.

BACKGROUND: Carcinoma of the scrotum is a rare disease which has been linked with occupational exposure to certain industrial carcinogens. Scanty reports of scrotal carcinoma exist in literature but in very few places worldwide. To our knowledge, there has been one documented report of scrotal carcinoma in our country and this is the first report of scrotal carcinoma in over 45years existence of our tertiary Health institution. We present the clinical evaluation, investigations and surgical intervention of a blind elderly welder with squamous cell carcinoma of the scrotum at the Obafemi Awolowo University Teaching Hospital, Ile-Ife, Nigeria. CASE PRESENTATION AND MANAGEMENT: A 65 year-old blind welder presented to us with a painless fungating scrotal mass of two years' duration. He had prior incision and drainage of the swelling in a primary health centre but this failed to heal, with copious purulent discharge. The mass measured 20cm x 15cm x 8cm and was inseparable from the right testis and cord structures, with infiltration of the root of the penis. The inguinal lymph nodes were not enlarged. CT scan confirmed localized scrotal tumour and biopsy confirmed squamous cell carcinoma.He subsequently had wide local excision of the scrotal tumour (with at least 2cm free margins), right total orchidectomy and advancement flap closure of scrotal defect. Histopathological reports corroborated the earlier findings and confirmed tumour free margins. He has remained well 18 months after surgery. CONCLUSION: Squamous cell carcinoma of the scrotum, though rare, is the commonest malignancy affecting the scrotum worldwide. Surgery still remains the mainstay of treatment and early intervention improves the chances of a favourable outcome.

Radiographic chest findings and immunological status in HIV-positive patients with tuberculosis coinfection in a sub-urban Nigerian tertiary hospital.

INTRODUCTION: The study was undertaken to assess chest radiographic features and lymphocyte counts among HIV-positive patients with TB coinfection. MATERIALS AND METHOD: We reviewed the chest radiographs of all newly diagnosed, treatment-naïve HIV-positive patients attending the Treatment Centre at the Olabisi Onabanjo University Teaching Hospital, Sagamu, Nigeria. The radiographs were examined for presence or absence of features of tuberculosis and pneumonia. Those with tuberculosis were further evaluated for presence of cavities and milliary appearance. The demographic characteristics of the patients were recorded. RESULTS: Two hundred and ninety-five radiographs were reviewed, consisting of 192 females, 103 males with mean ages of 33.6±11.65 and 37.85±13.54 years, respectively. Normal radiographs were found in 68.5% patients, features of tuberculosis in 27.8%, and pneumonia in 2.7%. The percentages of males and females with tuberculosis were 35% and 25%, respectively. Patients with milliary TB were from the youngest age group and those with cavities had CD4 cell count below 200cells/mm(3). Cavities occurred most frequently in the lower zones. WBC and counts were highest in patients with pneumonia. CONCLUSION: Normal chest radiographs were associated with mild clinical course. Males were more frequently involved in TB coinfection. Cavities were associated with lowest CD4 cell count and occurred more in lower zones. Patients with HIV/PTB coinfection had the most severe weight loss. There was no statistically significant difference in absolute lymphocyte count between patients with or without tuberculosis. Chest radiograph remains a veritable tool for identifying HIV/AIDS patients with tuberculosis whether sputum is positive or negative.

Drug resistance profiles of new- and previously treated patients with pulmonary tuberculosis in Ibadan, Nigeria.

BACKGROUND: Information on TB drug resistance profiles and its' associated risk factors are scarce in Nigeria despite the large burden of disease in the country. The study was designed to report drug resistance profiles of new- and previously treated patients with pulmonary tuberculosis (TB) in Ibadan, Nigeria. METHOD: Sputum from consenting pulmonary TB patients were collected and cultured for Mycobacterium tuberculosis (Mtb) at the TB laboratory of the University College Hospital, Ibadan, Nigeria using standard method. Mtb were stored and sent for drug susceptibility testing against first and second-line anti-TB drugs at the MRC Unit, The Gambia and at the Institute of Tropical Medicine, Antwerp, Belgium using BACTEC MGIT 960 and proportion method on solid medium respectively. RESULTS: Of 238 Mtb collected, 124 (52.1%) were viable, 102 (59.65%) non-viable while 12 (7.02%) were contaminated. About half (58.87%) of the Mtb were from previously treated patients, 40 (32.26%) were from new patients while treatment history of 1.1 (8.87%) were unknown. Forty-seven (37.90%) of the 124 Mtb. tested were multidrug resistant (MDR) out of which, 40 (85.10%) were from previously treated patients.. HIV prevalence was 8.69%. Of the 17 MDR-TB from previously treated cases tested for second-line drugs, four (23.53%) were resistant to fluoroquinolones or injectable agents, 13 (76.47%) were susceptible while none was resistant to both of these classes of drugs. CONCLUSION: MDR-TB in Ibadan already demonstrates resistance to second line anti-TB drugs hence management of MDR-TB patients should be strengthened to prevent emergence of extensively drug-resistant TB (XDR-TB).

Are there differences in disease progression and mortality among male and female HIV patients on antiretroviral therapy? A meta-analysis of observational cohorts.

Studies examining the sex differences in morbidity and mortality among HIV/AIDS patients have yielded inconsistent results. We conducted a meta-analysis of sex differences in disease progression and mortality among HIV/AIDS patients. Medical literature databases from inception to August 2014 were searched for published observational studies assessing sex differences in immunologic and virologic response, disease progression and mortality among HIV-infected patients. Random effects meta-analyses of 115 eligible studies were conducted to obtain pooled estimates of outcomes and heterogeneity was explored in sub-group analyses. Pooled estimates showed an increased risk of progression to AIDS (relative risk [RR]=1.11,95% CI=1.02-1.21) and all-cause mortality (RR=1.23, 95% CI=1.17-1.29) among males compared to females. All-cause mortality differed by sex only in low and middle income countries. The risk of AIDS-related mortality (RR=1.03, 95% CI=0.82-1.30), immunologic failure (RR=1.19,95% CI: 0.97-1.47), virologic suppression (RR=0.98, 95% CI=0.84-1.14), virologic failure (RR=1.26, 95% CI=0.99-1.61) and the change in CD4 cell count (Weighted mean difference [WMD] = -5.15, 95% CI= -13.57 to 3.28) did not differ by sex. These findings were modified by disease severity, adherence and use of highly active antiretroviral therapy. We conclude that HIV-related disease progression and survival outcomes are poorer in males.

Ultrasound evaluation of obstructive uropathy and its hemodynamic responses in southwest Nigeria.

PURPOSE: To determine the renal arterial hemodynamic changes induced by obstructive uropathy using Doppler ultrasonography. MATERIALS AND METHODS: 60 adult subjects with suspected obstructive uropathy and 60 asymptomatic apparently healthy controls with normal renal ultrasound features were evaluated. B-mode sonography of the kidneys and spectral Doppler examination of the renal interlobar arteries of all the participants were performed. The mean resistive indices (mRI) of both interlobar arteries were obtained and compared to that of the controls. The mRI of bilaterally obstructed kidneys were also compared with the mRI of unilaterally obstructed kidneys. RESULTS: The mRI of the right and left kidneys of subjects were 0.72±0.04 and 0.69±0.06 while those of the controls were 0.64±0.04 and 0.63±0.03 respectively. The mRI for the grades of caliectasis increased from grade I (0.72±0.03) to grade II (0.73±0.03) and grade III (0.73±0.02) but fell within the most severe levels of obstruction (0.69±0.07). There was no statistically significant relationship between the grades of caliectasis and unilateral or bilateral obstruction for both kidneys. The results show a sensitivity and specificity of 86.7% and 90% respectively when mRI≥0.7 was used to determine presence of obstruction. CONCLUSION: Renal duplex sonography is highly sensitive and specific for diagnosis of obstructive uropathy. Increased resistive index of the obstructed kidney may be a useful diagnostic tool in situations where intravenous urography cannot be done or is contraindicated.
