Primary bones cancers are rare and ubiquitous malignant tumors. Aim: Our study aimed was to describe the epidemiological and histopathological aspects of primary malignant bone cancers in Ivory Coast. Material and method: This is a retrospective and descriptive study of primary malignant bone cancers diagnosed over the period 1990 to 2013 (24 years). The studied parameters were: epidemiological aspects (frequency, age, sex, topography) and histological aspects. Results: Over the study period, primary malignant bone cancers accounted for 1.93% (n = 228) of cancers. The average age was 27.02 years with extremes of 2 and 85 years. The sex ratio was 1.65. They were in the skull and maxilla in 43.9% (n = 105), lower limbs (23.8%), spine and ribs (19.8%), pelvis (5.3%) and upper limbs (2.3%). The clinic was dominated by pain and alteration of general state. Radiology was variable depending on the histological type. In children, primary malignant bone cancers were found in the maxillary (77.9%) and the lower limb (15.8%). Burkitt’s lymphomas represented 36.4% (n = 66) of the histological types followed by 22.4% osteosarcomas (n = 51). In adults at histology, sarcomas were the most common (10%), followed by cancers of the hematopoietic and lymphatic organs (8.09%). Conclusion: Primary malignant bone cancers are rare in Ivory Coast. They most often affect male children with maxillofacial involvement and predominant lower extremity. Burkitt’s lymphoma and osteosarcoma are the often diagnosed histological types.

In a context of climate change and declining water resources, knowledge of low flow is essential. Present study deals with the spatial and temporal evolution of the streams low flow in Sassandra river. In the study, 12 stations of the Sassandra sub-basins (Sassandra, N’zo, Lobo, and Davo) were selected according to the availability and quality of long-term data. Annual, monthly and daily low flow data from twelve hydrological stations of the Sassandra watershed were used and cover the period from 1970 to 2015. The methodology used is concerned with extracting the low flow data and analyzing and evaluating the trends (Mann-Kendall) and change-point (cumulate sum) of low flow data. Statistical tests are applied to the mean and variance of the low-flow series. The results of the statistical tests show more trends and change points on the mean than on the variance. Significant trends show an increase in low flow waters. The significant change point detected by the cumulative sums test generally occurs between 1990-2007. In addition, tributaries are more affected by significant trends and change point detection than Sassandra river.

The purpose of this study is to identify the causes of mechanical complications of osteosynthesis of members to prevent and improve the results of our surgical treatments. Patients and Method: Retrospective study including all patients diagnosed with mechanical complications after osteosynthesis of the limbs and who received medical follow-up. 42 patients with an average age of 42.2 years, with a male predominance (36 cases) were selected. These complications predominated in the femur with 26 cases. The implants involved were predominantly screwed plates with 25 cases. We investigated and analyzed the different types of dismantling of material as well as the etiological factors that may be at the origin of these disassembly. Results: After a mean follow-up of 15.47 months, four types of complications were identified: material expulsion (20 cases), migration (3 cases), incurvation (7 cases), fracture of material (12 cases). 4 types of factors causing dismantling have been identified: the factors related to the patient, factors related to fracture, the factors related to the implant and factors related to the surgeon. Conclusion: Disassembly of orthopedic implants is most often of multifactorial origin. These factors may act in isolation but are most often entangled in the patient. Proper preoperative planning can help prevent them. However, unexpected stresses of the implant and certain factors related to the ground remain difficult to control.

Introduction :Infantile haemangiomas are the most common benign vascular tumours of infants. In Western countries, they have been the subject of several studies. However, in sub-Saharan Africa, few works are devoted to them. We initiated this work to contribute to a better knowledge of infantile haemangiomas in our work context. Material and Methods: This is a cross-sectional descriptive and analytical study carried out in the Dermatology Department of C.H.U. Treichville from November 2014 to December 2016;All children with infantile haemangiomas have been taken into account, in the study. Results: We counted 42 cases of haemangiomas on 4600 paediatric dermatoses, a prevalence of 0.9%. The sex ratio was 0.35. The age of our patients ranged from 2 days to 5 years. 76.2% of patients consulted after the age of 2 months. 26.9% of patients were born premature. 54% of the haemangiomas started with an erythematous macula. 52.4% had a size between 1 and 3 cm. Superficial haemangiomas (52.38%) and mixed haemangiomas (42.85%) were the most common clinical forms. The ulcerated forms represented 9.5%. The lesions were preferentially located in the cervico-facial region (71.4%) and resulted in aesthetic prejudice in 47% of cases. 3 patients (7.14%) were treated with propranolol. 37 patients (88.1%) used self-medication using poultice. Conclusion: Infantile haemangiomas are infrequent in cote d’Ivoire. They sit mainly in the cervico-facial area. The ulcerated forms are not negligible and they sometimes cause a significant aesthetic prejudice. Their management is sometimes difficult because of the unavailability of propranolol.

Congenital nephrotic syndrome (CNS) is defined as the presence of proteinuria > 50 mg/kg/24h associated with a protein concentration g/L or albuminemia 30 g/L in an infant less than 3 months old. The CNS is rare, of various clinical forms dominated by the Finnish type caused by a mutation of the NPHS1 gene located on chromosome 19. The edematous syndrome is the most common mode of discovery. We report a case discovered in an infant of 50 days admitted for ascites of great abundance. The aim of this study was to describe the main epidemiological, diagnostic, therapeutic and evolutionary aspects of this syndrome. Improving the prognosis of this condition requires advocacy with the political authorities of cote d’Ivoire to provide Teaching Hospital for the resources needed to perform kidney transplantation.

The sandy Quaternary and the deep Maastrichtian aquifers located in the northern coastal zone of Senegal, from the locality of Kayar in the south to Saint-Louis in the north, constitute the main sources of water supply for urban and local needs as well as mining activities. The Quaternary aquifer that provides the water required for the irrigation of local farmlands, hosts a significant heavy mineral sands deposit currently being mined by the Grande cote Operations (GCO). As a result of variable rainfall and increased water abstraction, this shallow aquifer has recorded a continuous water level decline since 1970, with potential negative effects on both the social and economic development of the region. The mining of heavy minerals (zircon, ilmenite, leucoxene and rutile) at GCO is realised through conventional dredging techniques that require large volumes of water (up to 60,000 m3/d). The water pumped by the dredge to enable the extraction of the heavy minerals, infiltrates into the shallow aquifer, runs-off into the dredge pond or evaporates. The objective of this study is to evaluate a water balance that enables the provision of a permanent water supply to the dredge pond, whilst minimising the risk of flooding of the cropping depressions adjacent to the mine site or drying out of the farming wells. The hydrodynamic model implemented for this purpose was calibrated and tested during the first year of operation. The Root Mean Squared Error (RMSE) obtained for the calibration is approximately 0.52 m. The predictions indicate a requirement for the system to recover part of the tailings infiltration through dewatering boreholes. The quantity of recycled water is estimated at 16,000 m3/d on average. The model simulations show an additional water requirement, extracted from the deep Maastrichtian aquifer, varying between 23,000 and 28,000 m3/d to achieve the optimum pond water level.

Objective: To describe the growth profile of breastfeeding babies following early introduction of infant formulas to improve the feeding pattern of the young infant. Methodology: This is a longitudinal descriptive study conducted in 2 medical clinics in Abidjan from 11-Jun-2013 to 15-Dec-2016 on 100 healthy newborn babies with the introduction of infant formulas before 6 months of life. The anthropometrics parameters were compared to those of WHO. Results: The exclusive breastfeeding rate was 5%. Ablactation occurred within 12 months in 95% of cases. All Infants have doubled and tripled their birth weight at 3 and 9 months respectively. The height and the head circumference at birth increased by 50% and 37% respectively at 12 months. Compared to WHO growth charts, the weight gain for the girls at 3 months was 12.4% higher and for the boys was 7.3% higher at 6 months. On the other hands, the statural gain at 12 months was 50% lower than the WHO standards while the head circumference was 37.8% and 45.5% higher than the WHO standards in boys and girls respectively. At 3 months, the prevalence of stunting was 26.1% for boys and 13.3% for girls. Lastly, at 12 months, the BMI showed 10% overweight and 19% obesity. Conclusion: Breastfeeding associated with an early introduction of infant formulas increases the risk of malnutrition of the young infant. We advise to avoid it and recommend an exclusive breastfeeding.

Aims: 1) To assess the feasibility of EPAGE criteria in clinical practice;2) To assess appropriateness colonoscopy using EPAGE criteria;3) To compare colonoscopy appropriateness and endoscopic lesions. Method: Hundred thirtynine consecutive patients explored by colonoscopy were included. The appropriateness of colonoscopy was evaluated by EPAGE criteria. Results: EPAGE criteria were applicable among 127 patients (91% of the cases). Colonoscopies were appropriate, uncertain and inappropriate in respectively 40%;27% and 24% of the cases. Rate of abnormal colonoscopies was significantly different between the 3 groups (p = 0.03). Cancers were diagnosed exclusively in the groups with appropriate and uncertain colonoscopies (11% and 5%). Colonic adenomas were observed in the three groups (appropriate (7%), uncertain (5%) and inappropriate (6%)). Subjects with uncertain indication were older (58.25 years;p = 0.035). Conclusion: EPAGE criteria are feasible in clinical practice in Cocody’s teaching hospital center. Colonoscopies are generally appropriate in our hospital. However, within sight of the significant number of normal colonoscopies and discovered lesions in uncertain indication, colonoscopy cannot concern exclusively calculation of a score of appropriateness.
