SS precursors play a fundamental role in investigating the earth's mantle transition zone (MTZ). More often, high-quality of SS precursors signals are required to obtain an accurate image of the transition zone. However, the SS precursor signals are generally weak with low amplitude because of the relatively small impedance contrast of the mantle discontinuities, the presence of strong noise, and incomplete seismic observations.

This study focused on the interpretation of geophysical data collected from the Sissedougou prospect which is located at the southern end of the Korhogo-M’Benguebirimian trench. The geophysical surveys were carried out on two grids with two magnetometers and an induced polarisation unit composed of a transmitter and a receiver. The magnetic data allowed on one side the mapping of basic, intrusive and volcanic formations, weakly magnetic rocks produced by meta-sediments to be showed, and on the other hand to identify the continuity of the shear corridor observed southward and northward of the prospect. Induced polarisation data revealed the signature of sulphide and disseminated mineralization. The synthesis of the obtained results showed that deep NE-SW, NNE-SSW and N-S oriented fractures promoted the late rise of sulphide fluids. The setting of sulphide and gold mineralization in the southern part of the Boundiali trench is therefore controlled by ductile and brittle shearing.

Hepatitis C infection in people living with Human Immunodeficiency Virus (HIV) poses management challenges. Of the world’s population, 3% are estimated to have chronic Hepatitis C Virus (HCV) infection, which is responsible for about 70% of cases of chronic hepatitis (accelerated chronicity in the presence of HIV and for such major complications as cirrhosis and hepatocellular carcinoma. The fibrosis 4 (FIB-4) and Aspartate aminotransferase/platelet ratio index (APRI) scores are simple, inexpensive tests accessible to most people, and their performance has not yet been studied in C?te d’Ivoire. Objective: To prospectively evaluate the diagnostic performance of APRI and FIB-4 scores in liver damage in those co-infected with HIV/HCV in C?te d’Ivoire. Methods: This study was conducted over three months. The patients came from national blood transfusion center of the cities of Man and Daloa. The criteria for selecting respondents were at least 18 years of age and a positive test for HIV and HCV. APRI and FIB-4 scores were calculated for each patient from biological data obtained by COBAS C311 (Roche Hitachi, Japan). Statistical analyses were performed using GraphPad and MED-CALC software. Results: Our study involved 30 patients (men) of middle age (25 - 52 years), with extremes ranging from 0.67 to 8 for APRI and 0.201 to 22 for FIB-4. A predictive APRI and FIB4 score of significant hepatic fibrosis was observed in 23% of patients;however, 46% and 54% of patients for the APRI and FIB-4 score, respectively, would not have significant fibrosis. An APRI and FIB4 score not included in the classification limits of the type of fibrosis hepatitis was observed in 31% and 23% of patients, respectively. Conclusion: The performance of the APRI and FIB-4 biological scores analyzed according to the interpretation of their cut-off values would enable classifying about 70% and 77%, respectively, of the patient population in the stages of hepatitis C fibrosis.

Background: Hematopoietic system is seriously affected by tuberculosis. It exerts a dazzling variety of hematological effects involving both cell lines and plasma components [1]. Anemia and leukopenia are not unusual with tuberculosis (TB), but pancytopenia is rare [2]. Findings: In this report, we described a case of a 42 years man presenting bleeding and pancytopenia;bacteriological pulmonary TB was established by genotypic rapid test and treatment following the WHO guidelines on drug-sensitive TB treatment. Patient recovered entirely with the WHO recommended regimen associated with general and local treatment of the bleeding. Conclusion: This case report emphasizes the importance of always suspecting tuberculosis in a tuberculosis-endemic area, even when the clinical manifestations are atypical, like pancytopenia and also of properly investigating the differential diagnosis. Even though prognosis seems to be less good, actual treatment regimen is still effective.

Malaria is a major public health problem in the Cote d＇Ivoire where it is the leading cause of morbidity and mortality. The objective of this study was to assess the knowledge, attitudes and practices of health care providers on the diagnosis and therapeutic procedures used to ensure the management of uncomplicated malaria in the health district of Abidjan. A cross-sectional study was conducted from November 2008 to December 2008 among 169 caregivers who treated 1,691 cases of uncomplicated malaria. Results： The knowledge of the caregivers of the national guidelines regarding malaria was sufficient （89%）. A diagnosis of uncomplicated malaria was established only on clinical arguments （70%）. The percentage of patients who were prescribed artemisinin-based combination therapy （ACT） was 86%. However, 25% of the antimalarials drugs that were prescribed to patients （oral quinine, artemisinin derivatives monotherapy, and herbal medicine） did not meet the recommendations on first choice treatment as suggested by the national program against malaria. These results indicate sufficient knowledge of the national guidelines for the treatment of malaria by health care providers as evidenced by acceptable prescriptions for ACTs despite an incomplete knowledge of the guidelines.

Objective: To describe the practice of artificial ventilation (VA) in a resuscitation unit of a developing country with a view to its improvement. Patients and Methods: Prospective study for descriptive and analytical purposes, carried out in the intensive care unit of the University and Hospital Center of Treichville (Ivory Coast) from April 2009 to June 2010. All the patients having benefited from a artificial ventilation for a duration greater than 6 hours were included in this study. The studied parameters were: Socio-demographic (age, sex), diagnostic, therapeutic (indications, duration and complications of artificial ventilation), evolutionary. Results: Out of a total of 204 admissions during the study period, 81 patients received artificial ventilation, an incidence of artificial ventilation in the order of 39.7%. There were 49 men and 32 women. The ventilated patients had an average age of 43.9 years (range: 4 years and 85 years). Pathologies requiring artificial ventilation were neurological (46%) and traumatic (28%). Stroke was the leading medical condition (65%) while polytrauma was the major traumatic condition (65%). The most commonly used ventilatory modes were controlled volume ventilation (52.4%) and assisted ventilation (34.9%). The mean duration of artificial ventilation was 5.98 ± 3.73 days (range: 1 day and 21 days). The nosocomial pneumonia acquired under mechanical ventilation (PAVM) constituted 27% of the complications observed under artificial ventilation. The average length of ICU stay for all ventilated patients was 9.85 +/- 7.51 days (range: 1 day and 31 days). The lethality in our series was 80%. Patient age was the only prognostic factor associated with death (P = 0.003). Conclusion: The practice of artificial ventilation is still difficult in Ivory Coast and is at the origin of many complications such as nosocomial pneumonia acquired under mechanical ventilation which complicate the life threatening of the patients.

Introduction: Eclampsia is a common cause of maternal mortality in developing countries. The objective of this study is to evaluate the practice of anesthesia for eclampsia in tropical Africa. Patients and Methods: Retrospective descriptive study on the parturients who benefited from eclampsia anesthesia in the operating theaters of the gynecology and obstetrics department, the University Hospital Center (CHU) of Bouake over a two-year period (January 2015 to December 2016). The parameters studied were: anesthetic risk assessment, anesthetic management, immediate anesthetic and post-anesthetic accidents and incidents. Results: Out of a total of 3831 emergency cesarean sections, 65 were for eclampsia, or 1.69% of obstetrical surgical activity. The mean age of the patients was 20.30 ± 3.34 years (range: 14 years and 39 years). Prenatal consultation was not performed in 70% of cases and 85% of patients were primiparous. Patients classified as ASA IIIU accounted for 75% of the population and in 62% of cases, the Glasgow score was between 9 and 12. Induction was achieved with thiopental in 98% of patients and vecuronium was the only muscle relaxant used. The most common fetal complications were hypotrophy (50%), prematurity (30%) and respiratory distress (40%). Postoperative anesthetic complications were agitation (70%) and wake delay (15%). Maternal mortality was 5% and the neonatal death rate was around 7.69%. The elements of poor maternal prognosis were the ASA IVU class (P = 0.015) and the Aldrete awakening score between 3 and 5 awakening (P = 0.001). Conclusion: Anesthesia for eclampsia at CHU of Bouake is difficult. It needs to be improved thanks to better equipment of the health structures.

A bad conservation of food is recognized as being one of the critical constraints upon food security among resource poor population across Africa. We have evaluated the traditional management of pests in fish in Central African Republic. The data were analyzed by a factor analysis of correspondence. The Group I contained sensitive species of fish to the attacks of Dermetes frishii, Dermetes lardarius and Dermestes carnivorus. There were: Labeocoubie, Mormyrus deliciosus, Polydactylus quadrifilis, Auchenoglanis occidentalis, Synodontis nigrita, Hydrocynus forskalli, Districhodus rostratus, Hydrocynus goliath and Mormyrusrume. The group II contained sensitive species of fishes to the attacks of D. maculatus. There were: Cyprinus carpio, Malapterurus electricus, Oreochromis mossambicus, Barbus occidentalis and Oreochromis mossambicus. Clariasgariecilus is the mostsensitive of dried fish to the attacks of Dermestes. Oreochromis mossambicus, Mormyrusrume and Synodontis nigrita are the last sensitive of dried fish to the attacks of Dermestes. The results showed that the tradictional management of dried fish in Central African Republic couldn’t be efficient for reducing the development of Dermestes.
