Objective: To describe the epidemiological, clinical and prognostic factors and assess treatment of placental abruption in the obstetrics gynecology department of the Dakar Principal Hospital. Patients and Method: We carried out a retrospective observational study of 130 successive cases of placental abruption, which occurred from January 2015 to December 2017 at the Level 3 Maternity Unit of the Dakar Principal Hospital. Data were collected from non-computerized obstetric records and analyzed using Excel and Epi info software. Results: There were 130 cases of placental abruption, that is a prevalence of 1.5%. The average age of onset of placental abruption was 30 years. The history of hypertension concerned 32.3% of patients, the average gestational age of 32.5 weeks at the time of diagnosis, grade 3 of Sher was found in 48.5% of cases. The outcome of the pregnancy was a caesarean section in 79.2% of cases, the average weight of newborns was 2058 g. The management of the complications required a blood transfusion and intensive care. A haemostasis hysterectomy was performed in 6.2% of cases. Stillbirth rate was 53.7% and maternal mortality was zero. Discussion and Conclusion: Placental abruption, a severe complication of pregnancy, is associated with high perinatal morbidity and mortality linked to the severity of the clinical picture, despite an improved maternal prognosis.

Introduction: Cancellation of surgical operation is a surgical operation registered in the official schedule the day before or added to the list after and not carried out on the operating day. The purpose of this work was to determine the causes of cancellation of elective surgical operations in a major pediatric surgery department in Senegal. Patients and methods: It was a prospective and descriptive study of 278 patients scheduled during a period of 13 weeks. The study took place between April 3rd, 2017, and January 31st, 2018. Mean age was 2.9 years with extremes of 3 days and 15 years. The age group of 29 days to 30 months was the most represented (62.2%). Sex ratio was 1.41. Causes of cancellation were categorized into administrative and organizational causes, patient-related causes and staff-related causes. Results: Cancellation rate was 29.4%. Patient-related causes were most common (51.2%). Upper Respiratory tract infection (URTI) was commonest reason within this category (57.5%). Organizational causes (28.1%) came second and were mainly represented by the unavailability of the operating room (60.8%) related to breakdowns of anesthesia equipment. Finally, staff-related causes (20.7%) were due for most to the unavailability of the anesthesiologist (12 cases/17). Conclusion: Majority of causes that led to cancellation of elective surgical operations in our Pediatric surgery department are related to intercurrent illnesses affecting the patient, in particular URTI.

In recent years (2003), Senegal has been confronted with many urban flooding problems that have become recurrent due to the configuration of its settlement. This is due to galloping population growth, climate change and a lack of planning and rainwater drainage networks. To fix these phenomena, Senegalese government has initiated rainwater drainage programs. In the city of Thiès, particularly in Sampathé district, flooding problem is a reality that is observed during every winter period. It is within this framework that we have proposed a project for the design and dimensioning of a rainwater evacuation network in Sampathé. The network will be integrated into a Geographic Information System for efficient management of project. This study involved identifying flood zones, determining geotechnical characteristics of the soil, and exploiting rainfall data in order to propose a storm water drainage network that will be integrated into a database management system. Thus, we carried out topographical and geotechnical studies, then designed and dimensioned the drainage network, and finally set up a geographic information system. At the end of this project, we designed a sewerage network consisting of two primary pipelines, four secondary pipelines, one tertiary pipeline, ninety-two manholes and a retention basin. To manage the network, we set up a geographic information system to geolocate various elements for rapid intervention in the field in event of a problem, make requests, generate thematic maps, and perform spatial analyses for good decision-making.

The aetiologies of hypereosinophilia are dominated by digestive parasitosis and drug intake. In the tropics, because of the frequency of parasitosis, eosinophilic digestive pathologies of primary origin, which are rare, may be overlooked. We report 6 cases of eosinophilic gastroenteritis with polymorphic digestive manifestations testifying to the different locations of eosinophilic infiltration in the digestive parietal layer. Three patients had ascites rich in eosinophils, indicative of serous involvement, while the other two had a muscular form, and the last a mucosal involvement. The evolution was favourable in all cases with corticosteroid therapy, but a recurrence was noted in 4 cases when treatment was stopped.

Objectives: To specify the epidemiological and clinical profile of the patients, to determine the methods of management and to evaluate the maternal and perinatal prognosis in the association of arterial hypertension and pregnancy (HTA) at the Institute of Social Hygiene of Dakar. Material and Methods: This was a retrospective, descriptive and analytical study on the management of the association of hypertension and pregnancy in the maternity ward of the Institute of Social Hygiene of Dakar between January 1st, 2019 and on December 31st, 2020. Results: During the study period, we recorded 326 cases of hypertension associated with pregnancy among the 4290 pregnant women, i.e. a frequency of 7.6%. The epidemiological profile of the patients was that of a woman with an average age of 29, nulliparous (48.2%), married (99.1%), at a low socioeconomic level (61.3%) and with a personal history preeclampsia (14.4%). Most patients (83.1%) were evacuated or referred with pre-ec- lampsia as the main reason (40.8%). The average gestational age was 37 weeks of amenorrhea (SA) with extremes of 20 SA 6 days and 41 SA 5 days. Term pregnancies were the most represented (76.7%). Prenatal follow-up (CPN) was carried out in 319 patients (97.8%) with an average number of CPN of 3 and extremes of 1 and 9. Severe diastolic and severe systolic hypertension concerned respectively 19.3% and 16, 9% of patients. One hundred and eighty patients (55.2%) presented with oliguria. Strip albuminuria was performed in 235 patients (72.1%). It found 3 or more crosses in 38.3% of cases. We recorded 53 cases of anemia (16.3%), 16 cases of significant proteinuria (5%), hepatic cytolysis in 22 patients (6.7%), thrombocytopenia in 37 patients (11.3%), and 43 cases of hyperuricaemia (13.2%). Obstetric ultrasound found 36 cases of severe oligohydramnios (11%), 8 twin pregnancies (2.4%) and an umbilical Doppler anomaly in 10 patients (3.1%). Pre-eclampsia was the most common clinical form

Objective: Determine the frequency of evacuations, specify the epidemiological and clinical characteristics of the evacuees, evaluate the data of the evacuation, the management and the maternal-fetal prognosis. Methods: Prospective and descriptive retrospective study concerning obstetrical evacuations received at the maternity ward of the Hospital of the Institute of Social Hygiene in Dakar between January 1 and December 31, 2020, i.e. a period of 12 months. Results: During the study period, we collected 1156 evacuees out of a total of 3507 patients treated in the Service, i.e. a frequency of 33%. The average age of the patients was 27.07 years with extremes of 14 and 46 years. Patients aged between 20 and 29 were the most represented (51.73%). The average parity was 1.6 with extremes of 0 and 10 pares. The nulliparous (46.37%) were the majority. The majority of evacuated patients (99.6%) resided in the Dakar region, including 58% in the suburbs and 42% in the city center. The patients received had performed an average of 3 prenatal consultations with extremes ranging from 0 to 9 CPN. They most often came from health centers (55.05%) or hospitals (29.09%). The reasons for evacuations were dominated by dystocia (21.54%) followed by premature rupture of membranes (17.21%) and premature deliveries (16.35%). On admission, only 176 patients (15.2%) had an evacuation sheet. Patients transited on average through two health structures (extremes ranging from 0 to 7 structures) before reaching the reception structure. The evacuation was most often done with a private vehicle on the patient’s own means (91.96%). The outcome of the evacuees was most often vaginal delivery or hospitalization (72.79%). The majority of patients (99.4%) had evolved favorably but we deplore one maternal death (0.09%) linked to a late puerperal infection. We recorded 74 perinatal deaths and 1041 live births, i.e. a stillbirth rate of 71.1‰ live births. The causes of death were dominated by prematurit

Journal of Shipping and Ocean Engineering 2016年第4期6卷 226-240页

作者： Moustapha Diagne Mamadou fall mouhamadou Bachir Diouf Ndeye Penda Dione El Hadji mansourSamb Department of Geology Faculty of Science and Technology Cheikh Anta Diop University Dakar - Senegal Chemical Industries of Senegal

The Tobrne panel is the third of the Ta＇fba phosphate deposit. This mineralogical study contributes to the improved knowledge of the various facies that comprise the phosphate series of Tobrne. Based on X-ray diffraction results, the Tobrne panel yielded minerals that are primarily divided into four groups： minerals of the original phosphate phase： apatite, fluorapatite; carbonate minerals： calcite and dolomite; clay minerals： palygorskite, smectite, kaolinite and illite; minerals of altered facies： alteration minerals （analcime, millisite, crandallite and wavellite） and ferruginous minerals （goethite and gibbsite）. This succession of mineralogical associations reflects a polyphase alteration leading to a vertical and lateral facies sequence. This alteration intensifies the phosphate series upward and laterally from West to East.

Journal of Water Resource and Protection 2021年第12期13卷 915-930页

Water contamination by chemical pollutants is increasingly associated with waterborne diseases worldwide. The objective of this study is to assess the chemical health risk associated with drinking water consumption in Dakar, Senegal. The methodology adopted in this study is based on the determination of trace metals (Cd, Pb, Fe, Cu and Mn) in human drinking water by flame atomic absorption spectrometry, the estimation of the exposure of populations of the study area on the basis of the quantity of water consumed daily and the determination of the hazard quotient which allows estimating the health risk. The results indicate unacceptable levels of Pb and Cd in the water according to World Health Organization (WHO) guidelines, while the concentrations of Fe, Cu and Mn are below the regulatory values. The hazard quotient (HQ) is in the majority of samples higher than 1 in children and infants for scenario 1 (based on WHO data), reflecting a high risk for this target. In scenario 2 based on consumption data from the populations studied, the HQ is greater than 1 only in heavy consumers. The drinking water consumed by Dakar population presents health risks related to Pb and Cd, particularly for infants, children and heavy consumers, hence the need to strengthen the water treatment system before home consumption.

Journal of Geoscience and Environment Protection 2018年第5期6卷 193-209页

The Tobène deposit forms, with those of NdomorDiop and KeurMor fall, the large phosphate deposit of Ta?ba. The Tobène site has been the subject of lithostratigraphic, biostratigraphic, mineralogical, petrographic and geochemical studies. The lithostratigraphic and biostratigraphic studies dated the series from Lutetian to Bartonian composed of five lithological units, which are assembled by [1] in three formations. The mineralogical study shows three groups of minerals associated with the different phosphatic facies identified in the various sectors of Tobène: 1) characteristic minerals of sedimentological conditions;2) minerals of diagenetic origin;3) minerals of alteration. The petrographic study allowed an inventory of the constituting visible grains of the microfacies as well as the different phases of diagenetic and post-diagenetic transformations that may have affected them. It thus appears that the phosphatic ore of Tobène has undergone an extensive diagenesis (compaction, dissolution-recrystallization, epigenesis) to which a relatively intense ferruginization has been added.
