Introduction: Leontiasis ossea is the most severe bone complication of the maxillae of chronic renal failure. The objective of this work is to determine the clinical, paraclinical and therapeutic aspects of this condition. Observation: A 42-year-old patient with chronic anuric terminal renal failure dialysis for 12 years had consulted for multiple maxillo-mandibular swelling evolving for 2 years deforming the face with discomfort to chewing. The biological assessment was: PTH: 5252 pg/mL, Ca2+: 2.86 mmol/L, free T3: 4.16 pmol/L, free T4: 6.55 pmol/L, TSH: 3.13 U/mL, serum protein: 61 g/L, Creatinine: 835 μmol/L. The maxillofacial CT noted heterogeneous diffuse thickening of the cranial vault and bones of the facial massif evoking leontiasis ossea with right mandibular brown tumor. The biopsy diagnosed fibrous gingival epulis. The patient had undergone modeling surgery, under general anesthesia after dialysis, of the right mandibular tumor whose histological result was Leontiasis ossea. Conclusion: Treatment is modeling surgery under hemostatic control.

Objective: The objective was to measure the prevalence of viral failure (VF) in HIV-1-infected children on first-line antiretroviral therapy (ART) in routine practice. Methods: Serial cross sectional analysis of viral load (VL) in HIV-1 infected children on first-line ART for ≥24 weeks was done. VL was measured by Real-Time-Polymerase chain reaction (biocentrics). Samples were collected at 6, 12, 24, 36, 48, 60 months of treatment. Main measurement: Virological failure (VF) defined by a one-off VL > 1000 copies/ml. Results: 375 children aged ≤16 years on first-line-ART were included. Median age at ART start was 4.2 years and ≥50% have started ART ≤3rd birthday. A total of 717 measurements of VL were collected. VF was rated between 18% and 26% from 6 - 60 months (mean 20.2%), 95% IC [13.1 - 27.3] at the threshold of 1000 copies/ml, not too different at the threshold of 400 copies/ml, 21% - 30% (mean 23.9%), 95% IC [16.3 - 31.5], p = 0.9. Conclusion: In Yaounde, almost 20% of children on first-line of adherent-ART can experiment VF while improving immune status urging improvement of adherence.

Animal pollination is a key of reproduction of more plants species including Gossypium hirsutum. This Malvaceae is the best cultivated oilseed plant in tropical and subtropical regions in the world. This research evaluates the interaction between Amegilla calens and Gossypium hirsutum from 2018 to 2019 based on the activities of the solitary bee on the flowers of this plant and their productive impact in field. The experiment was focused on four repeated treatments during the flowering phase: the first two were characterised by the existence or absence of protection of the flowers regarding all insects and the other two made up of flowers designed for the exclusive visit of A. calens or open then protected again without a visit from an insect or any other organism. Daily rhythm of activity, behavioural ecology, the pollination efficiency, the fruiting rate, the number of seeds per capsule and the percentage of normal seeds were evaluated. Among twenty insects species recorded A. calens is the most abundant with 30.72% of 655 visits and the most efficient pollinator. Amegilla calens is active on G. hirsutum flowers from 6 a.m. to 5 p.m. with a maximum activity situated from 8 a.m. to 9 a.m. All visits of this solitary bee are able to fertilize the flowers of Malvaceae. The mean duration of a visit per flower for pollen harvest is also more important (23.57 ± 0.96 sec) than nectar collection (13.69 ± 0.72 sec). For the two years, through its pollination efficiency, A. calens increased the fruiting rate by 20.30%, as well as the percentage of normal seeds by 32.39%. Therefore, we concluded that A. calens is the important pollinator and increases the fecundity and number of normal seeds of G. hirsutum.

Distribution patterns of selected heavy metals content in sediments from the Bay of Quiberon and Gulf of Morbihan were studied to understand the current heavy metals contamination due to urbanization and mariculture activities in the coastal area. Therefore, a survey was conducted and 196 sediments collected were characterized for heavy metals content using Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) after mix acid digestion process. The distribution maps of the concentrations of the heavy metals studied were produced as an isopleth map based on data interpolation by the ArcGIS software application. The association with the adverse effects on aquatic organisms was determined by the classification of the sediment according to the sediment quality guidelines. Therefore, two approaches were employed namely: direct comparison with Sediment Quality Guidelines (SQGs) by USEPA (United States Environmental Protection Agency) and comparison with other numerical SQGs, threshold effect level/probable effect level, and effect range low/effect range medium. In order to estimate the effect of multiple contaminations of heavy metals, the mean-ERM-quotient was calculated at each sampling point.

Introduction: Despite the progress recorded at the level of transfusion safety in Côte d’Ivoire, much remains to be done, particularly at the level of the medical selection of blood donors. The objective of the study was to make an assessment of the pre-donation capillary hemoglobin dosage for the year 2020 of the fixed collection, of the Blood Transfusion Center of Yamoussoukro. Method: This is a retrospective study that took place at the Yamoussoukro Blood Transfusion Center. The data collection related to all old and new blood donors were deemed suitable for the fixed collection of the year 2020. The method chosen for the pre-donation control is that of the portable hemoglobinometer of the HémoCue® type, more precisely 201+. Results: Of the 1160 blood donors in the study, the pre-donation hemoglobin level was not measured in 787 (67.8%) subjects of either sex. Of the subjects who had a pre-donation hemoglobin level performed, 97 (26%) blood donors had a sub-standard hemoglobin level, including 15 females and 82 males. Conclusion: Pre-donation hemoglobin testing of blood donors is effective in Yamoussoukro. However, efforts must still be made to improve the quality of the blood collected and to protect blood donors.

Diabetic retinopathy (DR) is one of the microvascular complications of diabetes. The aim of this study was to analyze the risk factors associated with the occurrence of diabetic retinopathy (DR) at the National University Hospital Center-Hubert Koutoukou MAGA (CNHU-HKM). Patients and method: this was a descriptive and analytical cross-sectional study with prospective data collection. It was carried out over a three-month period from July 10 to October 10, 2019. It concerned all patients suffering from diabetes mellitus and who consulted in the Endocrinology department during the study period. Results: the frequency of diabetic retinopathy was 30.46% (53/174 patients). A female predominance was observed with a sex ratio (M/F) of 0.57. The main modifiable risk factors were represented by occupation and those that were not modifiable were represented by the presence of old nephropathy, glycated hemoglobin, age of discovery of diabetes and its length of service. Diabetic retinopathy is a serious condition that can ultimately lead to blindness. The frequency of DR remains high in our study.

Background: Radiotherapy is one of the main therapeutic strategies used in cervical cancer. The first radiotherapy services in Cameroon have existed since 1987 and still treat by conventional radiation techniques. With the evolution of radiation techniques, acute, subacute, and late complications are minimized. Our study aimed to describe the profile of side effects in patients with uterine cervix cancer treated by conventional radiotherapy, still used in our services. Methods: This was a retrospective and descriptive study of the records of patients treated in the radiotherapy department of the Douala General Hospital from January 2015 to December 2019. Data concerning radiation-induced toxicities were collected using the CTCAE Version 4.0 classification. Data analysis was performed using SPSS version 20.0. Results: A total of 270 records were selected. The median age was 54 years. The mean total radiation dose was 55.9 ± 11.8 Gy and 71.1% of patients were treated for less than 8 weeks. We found a frequency of 66.7% of radio-induced lesions with 99% being acute. The main acute lesions encountered were radio dermatitis (40%), radiation cystitis (17.7%), and radiation proctitis (17.1%). As late lesions, we found one case of vaginal fibrosis (0.4%). Exclusive radiotherapy, classical fractionation, and total doses lower than 45 Gy seemed to decrease the toxicity linked to conventional radiotherapy. Conclusion: The frequency of side effects of radiotherapy for cervical cancer at the Douala General Hospital remains high. Early lesions are the most encountered but strategies should be put in place to better evaluate late lesions.
