Introduction: The incidence of acute renal injury (AKI) has increased in recent decades. Acute renal failure is defined by the abrupt arrest (within hours or days) of the kidney excretory function. Oliguria (urine output 24h) is presented in about half of the cases. The circumstances of the occurrence of AKI are multiple: surgical, traumatic, obstetric, medical, often obvious. Its prognosis depends on the speed of management and the associated organ failure. The objective of this study is to describe the profile of patients in emergency hemodialysis at the Nephrology Unit of the National Reference General Hospital (HGRN) in N’Djamena, Chad. Methods: This was a multicenter, descriptive study in patients with acute renal failure place over a period of 12 months in the emergency departments of the 2 hospitals in N’Djamena. Defined as carriers of an AKI (RIFLE criteria), patients with: 1) Oliguria: urinary output 400 ml/24h ( 350 μmol/l or decrease of GFR by 75%. Results: Of the 311 patients admitted, 36 cases met the inclusion criteria, a frequency of 11.57%. The mean age was 34.46 years with extremes ranging from 7 to 80 years. The female sex predominated with 52.80% as sex ratio of 0.91. Isolated hypertension was noted with 38.88%. Dyspnea accounted for 41.66% of patients admitted to emergency departments. In our series, 50% of our patients had hyperthermia at admission. Oliguria was observed in 41.70% of the cases. Edema accounted for 33.33% of cases. The AKI with the “failure” criterion was 58.34% (21/36), with the criterion “injury” 25% (9 cases) and the criterion “risk” 16.66 (6 cases). AKI were organic in 83.34% (30/36). It was noted that 14 patients, 38.8% had an infectious syndrome. There were 6 patients who had (16.66%) an obstructive AKI, 5 patients (13.88%) had eclampsia, 4 patients (11.12%) had hepatoce

Oral diseases belong to non-communicable diseases. They are characterized by their importance especially in disadvantaged areas. The objective of this study was to measure the extent and severity of caries among rural populations of Widou, an area located in central Ferlo. It was a descriptive and cross-sectional study which involved 300 individuals selected using simple random sampling. The socio-demographic characteristics collected were sex, age, educational level and occupation. The dental status was rated by the prevalence of dental caries and DMF and its components. The data were analyzed with the software Epi info 3.4.5 with 5% of threshold statistical significance. The prevalence of dental caries was 89%. The mean DMF was 5.4 ± 5.6 with a maximum of 26. The mean of component “D” was 3.8 with a maximum of 24. Variables significantly associated with dental caries were sex (p = 0.012) and occupation (p = 0.03). The extent and severity of caries in rural areas of the Ferlo evoke a relatively low support or management and require efforts in prevention, directed on oral hygiene and dietary habits.

Objective: The present study was aimed at evaluating the outcome of pregnancies with a nuchal cord. Methods: A retrospective population-based study of all deliveries during the years 2011-2020 in Philippe Maguilen SENGHOR Center was conducted. Perinatal outcome of patients with and without nuchal cord was compared. Results: Among 44,958 deliveries during the study period, 1.8% had a nuchal cord, documented at birth (n = 807). Higher rates of labor induction (9.1% vs. 3.2%;p 0.001) and non-reassuring fetal heart rate patterns (RR = 2.366;CI: 1.631 - 3.432) were noted among pregnancies with nuchal cord as compared with the control group. The cesarean delivery rate was significantly higher among pregnancies with a nuchal cord (39.5% vs. 21.8%;RR = 2333;CI: 2.023 - 2.692). Although 5 min Apgar scores lower than 7 were more common in pregnancies with a nuchal cord (7.8% vs. 3.8%;RR = 2.117;CI: 1.629 - 3.363). There was no statistical significance between the two groups for the perinatal mortality. Conclusion: Nuchal cord is associated with prolonged labor and adverse perinatal outcome.

The small size of agricultural plots is the main difficulty for crops mapping with remote sensing data in the Sahelian region of Africa. The study aims to combine Sentinel-1 (radar) and Sentinel-2 (Optic) data to discriminate millet, maize and peanut crops. Training plots were used in order to analyse temporal variation of the three crops’ signals. The NDVI (Normalized Difference Vegetation Index) was able to differentiate crops only at the end of the rainy season (October). The optical data as well as the radar ones could not easily discriminate the three crops during the growing season, because in that period vegetation cover is low, and soil contribution to the signals (due to roughness and moisture) was more important than that of real vegetation. However, the ratio of VH/VV (VH: incident signal in vertical polarization and reflected signal in horizontal polarization;VV: incident signal in vertical polarization and reflected signal in horizontal polarization) gave a difference between millet and the two other crops at the beginning cultural season (July 11). Difference appears from the second third of September when the harvest of cereals crops (millet and maize) began. From middle of October, the peanut signal dropped sharply thus facilitating the differentiation of peanut from the two other crops. This analysis led to the identification of data that have could be used to discriminate these crops (useful data). Classification of the combined useful data gave an overall high accuracy of 82%, with 96%, 61% and 65% for peanut, maize and millet, respectively. The non-agricultural areas (water, natural vegetation, habit, bare soil) were well classified with an accuracy greater than 90%.

Introduction-Objective: Tuberculosis (TB) is the leading cause of death from a single infectious agent worldwide. The predictors of mortality due to TB are rarely evaluated in Senegal. The aim of our study was to identify factors associated with related TB death in two treatment centers in Dakar, Senegal. Method: We conducted a prospective descriptive-analytical study dealing with TB patients followed in the Department of Infectious and Tropical Diseases at FANN Teaching Hospital and Dakar Principal Hospital and in the Department of Pulmonology at Dakar Principal Hospital from March 1st, 2019 to February 29th, 2020. Univariate and multivariate logistic regressions were performed to identify the associated factors of death. Results: Two hundred eighty-two patients in the Department of Infectious and Tropical Diseases at FANN teaching hospital (57%), in the Department of Infectious and Tropical Diseases at Dakar Principal Hospital (31%), and in the Department of Pulmonology at Dakar Principal Hospital (12%) were included in the study. The mean age was 39 ± 16 years and the male to female ratio was 2.2. Isolated pulmonary TB, isolated extrapulmonary TB, and both pulmonary and extrapulmonary TB were present in 33.3%, 30.5% and 36.2% of cases, respectively. Twenty-two patients died, corresponding to a mortality rate of 7.8%. Factors independently associated with death were age ≥ 60 years (26.2 [3.6 - 191.2]) compared to 16 - 40 years’ age group, HIV infection (7.2 [1.4 - 36.9]), neurological localization of TB (13.19 [3.2 - 54.3]), and hemoglobin level Conclusion: Tuberculosis remains a fatal disease despite therapeutic advances. Better knowledge of associated factors of death from TB may help to reduce its mortality.

“Locked twins” is a rare event occurring in about 1 in every 1000 twin births. A 21-year-old primigravida with a 31-week twin pregnancy was admitted for delivery. The head of the first twin was locked to the chin of the second twin at the top of the symphysis pubis. Caesarean section was performed allowing the delivery of both dead twins. Twins gestations with first twin in the breech presentation raise index of suspicion of potential locked twin. However, management of such situation is controversial with most authors and colleges recommending caesarean section to avoid interlocking heads. We report another rare case of interlocking heads and bring up the topic about management of breech-first twin deliveries.

Objective: Describe the epidemiological, diagnostic, therapeutic and evolutionary profile of triple negative breast cancer at the Dakar Cancer Institute in Senegal. Patients and Methods: This was a retrospective study between January 1, 2011 and December 31, 2014. All patients with a triple negative molecular profile were included. The data were collected from the medical records of the patients. The data were entered and analyzed with SPSS edition 16 software under Windows 7. Results: Two hundred and twenty-five patients were selected. The mean age was 47.9 ± 12.5 years with extremes of 25 and 90 years. The main reason for consultation was dominated by the finding of a breast lump. The mean clinical tumor size was 8, 54 cm with a large majority of T3-T4 tumors 26% and 63% respectively, lymph node involvement in one hundred and seventy-two cases (76.4%);twenty eight patients (12.4%) were metastatic from the outset. Non-specific invasive carcinoma was the most common histologic type (78.2%), and more than half of the patients (53.3%) had an aggressive tumor (Scarff-Bloom-Richardson grading III). Neoadjuvant chemotherapy was performed in 65.78% of cases. We noted 27.7% total response and 41.7% partial response in patients who have received this neoadjuvant chemotherapy. The surgery was radic

Multiple myeloma is on the list of neoplasia that may be associated with human immunodeficiency virus infection. It is an affection that aggravates the prognosis in these particular patients. We present the case of a patient with multiple myeloma and HIV infection, revealed by renal failure. This was a 59-year-old patient who was received to the Department of nephrology for renal failure associated with severe aregenerative pancytopenia. In etiological investigations, multiple myeloma associated with HIV1 infection was found. The evolution was unfavorable, marked by the death of the patient caused by digestive haemorrhage before the start of antiretroviral treatment and chemotherapy.

Context: Technological advances have improved the toxicities of radiotherapy. We are evaluating the 3D technique in prostate cancer. Materials and Methods: Retrospective study from January 2015 to December 2015 with 29 files. Survival was calculated by Kaplan-Meier method. Results: We collected 29 patient records over the study period. The median age was 75 years with the following extremes: 54 years and 83 years. The median PSA level was 12 ng/ml with a range of 3.05 to 79 ng/ml. Gleason score analysis showed 6 patients (20.69%) with a score of 6 (3 + 3), 23 patients (79.31%) with a score of 7 including 12 patients (41.38%) with grade 3 and 11 patients (37.93%) with grade 4. The median dose delivered was 74 Gy, with a mean dose of 73.79 Gy and extremes of 70 Gy for the minimum and 76 Gy for the maximum. Hormone therapy was combined with radiotherapy in 17 patients (58.62%). Seven patients (24.14%) had grade 1 acute bladder toxicity and one patient (3.45%) had grade 2 acute toxicity. Late bladder toxicity was grade 1 in 5 patients (17.24%), grade 2 in 3 patients (10.34%) and grade 3 in 1 patient (3.45%). Late rectal toxicity, grade 2 in 3 patients (10.34%), grade 3 in 1 patient, was noted. Overall survival at 2 years was 100% and 89.65% at 5 years. Relapse-free survival at 2 years was 82.76% and 62.07% at 5 years. There were 3 deaths (10.34%) of which only one was related to prostate cancer.
