Oxytocin via Uniject (a prefi lled single-use injection) versus oral misoprostol for prevention of postpartum haemorrhage at the community level: a cluster-randomised controlled trial
Background Access to injectable uterotonics for management of postpartum haemorrhage remains limited in Senegal
outside health facilities, and misoprostol and oxytocin delivered via Uniject have been deemed viable alternatives in
community settings. We aimed to compare the effi cacy of these drugs when delivered by auxiliary midwives at
maternity huts.
Methods We did an unmasked cluster-randomised controlled trial at maternity huts in three districts in Senegal.
Maternity huts with auxiliary midwives located 3â21 km from the closest referral centre were randomly assigned
(1:1; via a computer-generated random allocation overseen by Gynuity Health Projects) to either 600 ÎŒg oral
misoprostol or 10 IU oxytocin in Uniject (intramuscular), stratifi ed by reported previous year clinic volume
(deliveries) and geographical location (inland or coastal). Maternity huts that had been included in a previous study
of misoprostol for prevention of postpartum haemorrhage were excluded to prevent contamination. Pregnant
women in their third trimester were screened for eligibility either during community outreach or at home-based
prenatal visits. Only women delivered by the auxiliary midwives in the maternity huts were eligible for the study.
Women with known allergies to prostaglandins or pregnancy complications were excluded. The primary outcome
was mean change in haemoglobin concentration measured during the third trimester and after delivery. This study
was registered with ClinicalTrials.gov, number NCT01713153.
Findings 28 maternity hut clusters were randomly assignedâ14 to the misoprostol group and 14 to the oxytocin
group. Between June 6, 2012, and Sept 21, 2013, 1820 women were recruited. 647 women in the misoprostol group
and 402 in the oxytocin group received study drug and had recorded pre-delivery and post-delivery haemoglobin
concentrations, and overall 1412 women delivered in the study maternity huts. The mean change in haemoglobin
concentrations was 3·5 g/L (SD 16·1) in the misoprostol group and 2·7 g/L (SD 17·8) in the oxytocin group. When
adjusted for cluster design, the mean diff erence in haemoglobin decreases between groups was not signifi cant
(0·3 g/L, 95% CI â8·26 to 8·92, p=0·71). Both drugs were well tolerated. Shivering was common in the misoprostol
group, and nausea in the oxytocin group. Postpartum haemorrhage was diagnosed in one woman allocated to
oxytocin, who was referred and transferred to a higher-level facility for additional care, and fully recovered. No other
women were transferred.
Interpretation In terms of eff ects on haemoglobin concentrations, neither oxytocin nor misoprostol was signifi cantly
better than the other, and both drugs were safe and effi cacious when delivered by auxiliary midwives. The
programmatic limitations of oxytocin, including short shelf life outside the cold chain, mean that misoprostol could
be more appropriate for community-level prophylaxis of postpartum haemorrhage
Profil clinique et évolutif des lésions de la peau et des parties molles chez les diabétiques en 2017 à la salle de pansement du Centre Marc Sankale de Dakar
Introduction: le but de notre étude était de déterminer le profil clinique et évolutif des lésions de la peau et des parties molles des sujets diabétiques suivis à la salle de pansement.
Méthodes: il s'agissait d'une étude observationnelle descriptive et analytique menée du 1er janvier au 31 décembre 2017 à la salle de pansement du centre Marc Sankale de Dakar. Notre étude a porté sur les sujets diabétiques ayant consultés à la salle de pansement.
Résultats: au total, 37173 actes de soins ont été enregistrés au centre Marc Sankale. Les activés de soins à la salle de pansement représentaient 16418 cas soit une prévalence de 14,16%. L'ùge moyen était de 56,6 ± 12 ans et le sex ratio (H/F) de 0,88. Le diabÚte de type 2 prédominait (78,97%) et la durée moyenne du diabÚte était de 8,06 ± 7,9 ans. La glycémie capillaire moyenne était de 2,4 ± 1 g/l. La neuropathie diabétique était présente chez 72,33% des cas. Les lésions se situait aux membres dans 93,98% (1185 cas). Les lésions les plus représentatives étaient l'ulcÚre (46,76%), l'abcÚs (13,46%), le phlegmon (13,20%), la gangrÚne (8,41%), l'érysipÚle (3,78%), le mal perforant (3,53%), l'intertrigo (3,95%). Les lésions étaient infectieuses (61,41), non infectieuses (33,50%), vasculaires pures (1,57%) et Mixtes (3,70%). Sur les 1189 patients 7,57% avaient présentés une ostéite. Les germes retrouvés étaient des bactéries grams positifs (12,70%), grams négatifs (23,80%). L'amputation était corrélée à la topographie de la lésion (p=0.00), au type de lésion (p=0.000), à l'ancienneté du diabÚte (p=0,02), au type de diabÚte (p=0,008), à la présence d'ostéite (p=0,006). L'amputation etait mineur (43,33%), et majeur (37,43%). Nous avons enregistré 70 décÚs (5,89%).
Conclusion: les lésions de la peau et des tissus mous restent dominées par le pied diabétique. La mortalité est non négligeable et le risque d'amputation était statistiquement corrélé à la topographie, au type de lésion, à l'ancienneté et le type de diabÚte et à l'existence d'ostéite
Une lesion cutanée persistante non cicatricielle depuis 3 ans: le pyoderma gangrenosum
Le pyoderma gangrenosum (PG) est une dermatose neutrophilique non infectieuse rare souvent méconnue. Il se présente généralement par des ulcérations cutanées inflammatoires, trÚs douloureuses et d'évolution rapide. Il est fréquemment retrouvé dans un contexte de néoplasie, de pathologies inflammatoires digestives, rhumatologiques et/ou hématologiques. Son diagnostic est trÚs souvent tardif aprÚs de multiples échecs thérapeutiques. Nous rapportons un cas de pyoderma gangrenosum dont le diagnostic n'a pas été criant. Un patient a été admis dans notre service pour une lésion dermatologique persistante et d'évolution défavorable malgré les débridements et l'administration d'antibiotiques. Il était suivi pour un cancer de la prostate, une hypertension artérielle et un asthme. Du fait des anomalies biologiques observées telles qu'une hyperleucocytose à polynucléaires neutrophiles avec myélémie à myélocytes et métamyélocytes, sans blastose sanguine et une anémie normochrome normocytaire, une leucémie myéloïde chronique a été évoquée chez ce patient. Elle a par la suite été infirmée devant les différents examens complémentaires non concluants. C'est ainsi que le diagnostic de PG a été évoqué et confirmé à l'examen anatomopathologique montrant un aspect histopathologique d'un tissu de granulation concordant avec un pyoderma gangrenosum et une absence de signe histologique de malignité. L'institution d'un traitement à base de corticothérapie a abouti à la guérison
Effects of lenten fasting on body composition and biochemical parameters
Background: The catholic lenten fasting is the period of 40 days of fasting that precedes Easter. It is one of religious fasting less documented in the scientific literature. Thus the aim of our study was to evaluate the evolution of anthropometric and body composition and biochemical profile during Catholic lenten fasting.Methods: We conducted a prospective study, which took place during the period between one week before at the end of lenten fasting. Eleven fasters (4 women and 7 men), aged between 18 and 59 years were included in present study. Anthropometric, body composition parameters and biochemical profile were evaluated one week before, at 15th day and at the end of Lenten fasting.Results: Weight, body mass index (BMI) and visceral fat decreased significantly at the end of Lenten fasting. Lipid profile changed significantly during this fasting period. Total cholesterol (TC), low density lipoprotein â cholesterol (LDL-C) and triglycerides decreased significantly with fasting. High density lipoprotein â cholesterol (HDL-C) was remained unchanged during this fasting period while TC/HDL ratio was significantly decreased at the end of Lent.Conclusions: Present study showed that the fasting of Lent seems to have beneficial effects on reducing cardiovascular risk factors. Further studies are required to better understand the physiological mechanisms involved for a therapeutic use
The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance.
Investment in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing in Africa over the past year has led to a major increase in the number of sequences that have been generated and used to track the pandemic on the continent, a number that now exceeds 100,000 genomes. Our results show an increase in the number of African countries that are able to sequence domestically and highlight that local sequencing enables faster turnaround times and more-regular routine surveillance. Despite limitations of low testing proportions, findings from this genomic surveillance study underscore the heterogeneous nature of the pandemic and illuminate the distinct dispersal dynamics of variants of concern-particularly Alpha, Beta, Delta, and Omicron-on the continent. Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve while the continent faces many emerging and reemerging infectious disease threats. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century
The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance
INTRODUCTION
Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic.
RATIONALE
We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs).
RESULTS
Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants.
CONCLUSION
Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century

Sexuality of adolescent girls born with HIV in Senegal: an anthropological analysis
Objectives: In Senegal, the dominant social norm upholds virginity before marriage and edifies abstinence for adolescents as a cardinal moral value. Currently, sex outside of marriage remains socially condemned. The onset of sex for adolescent girls born with HIV in Senegal brings up several challenges. In Dakar, initiatives, especially through digital applications, are being developed to support these young people. These programs are much rarer in rural settings. A study conducted in 2021 explored how adolescent girls born with HIV who live outside of Dakar experience sexuality, what socio-health constraints they face, and what support they receive from the healthcare system. Method: An anthropological study titled âTreatment Failure among Children and Adolescents Living with HIV in Senegal, Outside Dakarâ (ETEA-VIH, ANRS 12421) was conducted in 2021 in 14 regional hospitals and health centers. Semi-structured interviews were conducted with 87 HIV-positive children and adolescents, 95 parents/guardians, and 47 health care workers. Adolescent girlsâ onset of sexuality was specifically analyzed for 40 adolescent girls age 12â19âyears old. Results: Generally, parents feign oblivion about their childrenâs sexual lives. Mothers dread a pregnancy out of marriage because they are responsible for overseeing sex education and would be âblamedâ for the transgression. The occurrence of an unintended pregnancy can lead to exclusion from the family and a risk of transmitting HIV to the child due to the lack of medical and social support. HIV remains a stigmatizing disease that families keep secret. The risk of disclosure is a major concern. Despite sexual and reproductive health (SRH) programs, most healthcare workers are reluctant to discuss sexuality or to offer contraception to adolescent girls. Information spaces have been set up in some regional hospitals by associations trained in SRH. They are rarer in health centers. Accessibility to digital applications and discussion forums is limited due to the lack of smartphones and Internet access. Conclusion: In rural settings, HIV-positive adolescent girls are confronted with the silence that surrounds sexuality and HIV. An individualized approach and confidential access to contraception should be prioritized to support them with assistance from PLHIV associations
Setting priorities for disaster management in the East African sub-region
La localisation cervicale de la tuberculose est rare et peut prendre l'apparence d'un cancer du col utérin. La présentation pauci-symptomatique et l'évolution insidieuse sont à l'origine d'un retard diagnostique. Les symptÎmes communément rencontrés sont non spécifiques, ce qui contribue au retard thérapeutique et majore le risque d'infertilité qui reste la séquelle quasi inéluctable. Nous rapportons un cas de tuberculose du col utérin dont le diagnostic de prime abord n'a pas été évident. En effet une patiente a été adressée à notre département pour suspicion de cancer du col utérin. Le diagnostic de suspicion de cancer a été alors retenu devant un col qui saignait au contact avec une tomodensitométrie abdomino-pelvienne en faveur d'une tumeur du col utérin. Une biopsie de confirmation histologique a été indiquée. On a retrouvé à l'examen anatomopathologique, un granulome épithélio-giganto-cellulaire avec nécrose caséeuse, compatible avec une tuberculose cervicale. La recherche d'un terrain était négative. Un traitement antituberculeux instauré a conduit à la guérison. Retenue souvent sur la base d'éléments présomptifs, la décision diagnostique et thérapeutique de tuberculose du col cervicale reconnait la place de l'examen anatomopathologique
