Evaluation De La Prematurite Superieure Ou Egale A 32 Semaine D’amenorhée A L’hopital Regional De Ziguinchor Au Sud Du Senegal (Afrique De L’ouest)

Introduction: Prematurity is one of the leading causes of neonatal death in Africa. The objective of this work was to assess the preterm birth at the pediatric service of the regional hospital of Ziguinchor. Material and methods: This was a prospective, descriptive and analytical study of the case of hospitalized newborns whose age was between 32 SA to 36SA + 6 days. The study was conducted from May 21, 2013 to May 21, 2014. We included all premature infants at age ≥ 32SA.Those presenting a malformation were not included. We studied maternal socio-demographic, obstetric and neonatal parameters. Results: We have identified 140 newborns out of a total of 342 Preterm births and 2292 maternity births, a prevalence of 40.9% compared to preterm infants and 6.10% in relation to all births. 51.4 percent of mothers came from urban areas, 63.5 percent were between 20 and 34 years of age, not attending school in 45.7 percent, married in 72.9 percent and without work in 94.3 percent. The average gestures represented 3.09 . Arterial hypertension was the most common medical condition (67.7%). The followup was done by a midwife (82.1%) and 23.5% had received at least 4 NPC. Eclampsia and pre-eclampsia (48.9%) and RPM (42.8%) were common obstetric pathologies. The delivery was by caesarian (51.4%), hospital (92.1%), cephalic presentation (80%), with an average weight of 1816.79 g. An RCIU (16.4%), an RPM (61.9%). At birth, a DR (16.4%) was noted due to MMH (43.7%) and transitory tachypnea (50%). Asphyxia was reported in 3.5%. During hospitalization (6.7 days on average), 6.4% had RD caused by infection (77.7%). Other complications were infection (64.4%), hypoglycemia (28.5%), digestive hemorrhage (7.01%). The fatality rate was 7.9% due to infection (63.3%), DR (18%), haemorrhage (9%). The anthropometric measurements at the exit: P 1887.9g, T: 38.3cm, PC: 30.9cm; at 1 month P: 2387.1g, T: 46.6cm, PC: 32.8cm; at 30 months P: 12.1kg, T: 89.5cm, PC: 48.4cm. Conclusion: Moderate preterm birth accounts for almost half of the cases of prematurity in our series. Their optimal management would go through a better obstetric-neonatal collaboration but above all by the installation of kangaroo mother unit

Insuffisance Rénale Aigue Obstétricale : Expérience De La Maternité Issaka GAZOBY De Niamey (Niger)

Introduction Acute renal failure (ARF) is a serious obstetric complication of pregnancy, a real health problem in developing countries. It is more related to the pathologies of pregnancy affecting the mother rather than the fetus. The purpose of our study was to assess sociodemographic, clinical, therapeutic and evolutionary features in obstetric acute renal failure. Materials and Methods: A cross sectional study of 6 months (August 2015- January 2016) was conducted. The study involved pregnant women over 20- week amenorrhea including the immediate postpartum admitted for acute renal failure. Results: Thirty-two patients were involved. The mean age was 25.21 ± 5.14 years. Most of them were first-time mothers (53.1%). Surrounding hospital exits account for 71.9% of the admissions. 31.25% (N = 10) of the patients did not receive any antenatal care. The main clinical signs at admission were hypertension (86.6%), oliguria (40.5%) and edema syndrome (37.5%). Eclampsia and severe pre-eclampsia represented the causes of the ARF in 68.75% cases. Considering 8 patients (25%) who were supposed to undergo dialysis therapy, only one took the treatment. The average hospital stay was 15.20 ± 7.45 days. Renal function resolved in 68.75% of patients and 15.62% developed chronic renal sequelae. At the end of the study, we recorded 5 cases of maternal deaths and 10 cases of fetal death in utero. Conclusion: Obstetric ARF remains a serious complication of pregnancy for mother and child. It should be noted that hemodialysis was not accessible to all patients who were entitled to it due to lack of financial means. Therefore, regular monitoring of pregnancies should be prioritized, and, if possible, ensure that hemodialysis sessions are funded

Décentralisation De La Dialyse Au Sénégal : Expérience D’1 An Du Centre De Tambacounda A l’Est Du Pays

Hemodialysis has made numerous and significant progress in recent decades resulting in life expectancy increase (thirty or forty years). The aim of our study was to assess the treatment of acute and chronic hemodialysis in the reference center of Tambacounda. Patients and methods: This was a prospective study over a one-year period (April 2013 to March 2014) in the hemodialysis center of the regional hospital of Tambacounda, 450km away from Dakar. The study focused on epidemiological, clinical, paraclinical and scalable data. Results: Fifty-nine patients were involved in the study. The sex ratio was 0.85 (32F/ 27M). The mean age was 41.3 years [12-72 years old]. Nineteen patients were on dialysis treatment for acute renal failure (ARF) (32.2%) and 40 were chronic hemodialysis patients (67.79%). Fifty patients were under emergency dialysis (84.7%) including 17 in intensive care (28.8%). Most chronic hemodialysis patients had 3 sessions per week (98.3%). Only 9 patients were monitored in nephrology prior to dialysis (22%). Thirty-two patients had a femoral double-lumen catheter (54.23%), 6 patients used ordinary double- lumen jugular catheters (10.17%) and 3 received tunneled jugular catheters (5.09%). Eighteen patients had functional arteriovenous (AV) fistula (18.51%). The mean hemoglobin was 7 g/dl. Only 11 patients had erythropoietin-based therapy. In acute renal impairment there were 8 deaths (42.10%), whereas in chronic renal failure the fatality rate was 18.8% (n = 9). Conclusion: Our study has demonstrated the benefits of decentralizing dialysis treatment in the provinces. However there is a need to implement the accompanying measures, such as the availability of some essential medicines for all hemodialysis patients, and equipment of intensive care units

Note sur la séro-anthropologie de trois populations de Guinée et du Sénégal : Coniagui, Bassari et Bedik (groupes ABO, MN, Rh, P, Kell, Gm et hémoglobines).

The ABO, MN, Rh (CDE), P, Kell, Duffy and Gm groups and the haemoglobins are studied in three West African Populations (213 Coniagui, 147 Bassari, 165 Badik for the ABO system ; 54 Coniagui, 147 Bassari, 164 Badik for the remaining groups). The first results published in this preliminary paper give some informations about the differences existing between these three populations, geographically close. They constitute the beginning of a larger sero-anthropological survey, on demographic and genealogical basis, which aims the description of the different populations living in the « Departement de Kédougou » (Senegal Oriental) and no definite conclusion is given. The paper ends by an account of the technics used in the samples collection and of the difficulties encountered in a tropical area. BULL. ET MÉM. SOCIÉTÉ ANTHBOP.

Comprehensive Phylogenetic Reconstructions of Rift Valley Fever Virus: The 2010 Northern Mauritania Outbreak in the Camelus dromedarius Species

International audienceRift valley fever (RVF) is a mosquito-borne disease of domestic and wild ruminants caused by RVF virus (RVFV), a phlebovirus (Bunyaviridae). RVF is widespread in Sub-Saharan Africa. In September of 2010, an RVF outbreak occurred in northern Mauritania involving mass abortions in small ruminants and camels (Camelus dromedarius) and at least 63 human clinical cases, including 13 deaths. In camels, serological prevalence was 27.5-38.5% (95% confidence interval, n=279). For the first time, clinical signs other than abortions were reported in this species, including hemorrhagic septicemia and severe respiratory distress in animals. We assessed the presence of RVFV in camel sera sampled during this outbreak and generated whole-genome sequences of RVFV to determine the possible origin of this RVFV strain. Phylogenetic analyses suggested a shared ancestor between the Mauritania 2010 strain and strains from Zimbabwe (2269, 763, and 2373), Kenya (155_57 and 56IB8), South Africa (Kakamas, SA75 and SA51VanWyck), Uganda (Entebbe), and other strains linked to the 1987 outbreak of RVF in Mauritania (OS1, OS3, OS8, and OS9)

Particularities of COVID-19 infection in chronic hemodialysis patients in Sub-Saharan Africa: experience from Senegal (West Africa)

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) appeared in December 2019 in China and has rapidly become a major global health concern. Patients with end-stage renal disease receiving dialysis treatment are very exposed to the SARS-CoV-2 during their frequent visits to healthcare facilities and immune induced by uremia. The aim of our work was to describe the particularity of COVID-19 infection in hemodialysis patients in sub-Saharan Africa and in Ziguinchor, south of Senegal, particularly. To do this, we conducted a monocentric prospective study over a period of 16 months at the Ziguinchor hemodialysis center and compared our results to a study that focuses on the seroprevalence of SARS-CoV-2 in chronic hemodialysis patients. We found a low prevalence of COVID-19 infection while the majority of our patients were in contact with the virus
