Septic arthritis is a serious disease and its treatment remains a major challenge. Demonstration of the microorganism is the key to diagnosis according to all international guidelines. In developing countries such as Madagascar, where access to basic health services is still difficult, bacteriological analysis of the joint fluid is not yet available in most healthcare facilities. We propose effective solutions that are scientifically valid, adapted to the country's socioeconomic conditions and current health situation, while taking international recommendations into consideration. We propose that the few university hospitals with rheumatology departments and good reference laboratories should be supported to participate in a pilot program to compile data to establish the clinical and bacteriological profiles of septic arthritis here. In lower level health centers where bacteriological examinations of the joint fluid and other complementary tests are more or less impossible, a diagnosis of septic arthritis is mainly based on clinical findings. Accordingly, all diagnosis and management should be centralized in these reference centers, which will allow the adaptation and progressive update of guidelines for the management of septic arthritis.

The study aims to establish the sociodemographic profile of consumers of garba (a street food sold in Côte d'Ivoire), understand its frequency of consumption, and develop a typology of its consumers. We interviewed 547 consumers at 10 points of sale. A factorial analysis of the data collected was performed and a decision tree produced for the social and demographic variables, followed by a multiple correspondence analysis (MCA) and then a hierarchical ascending clustering (HAC). Garba is consumed more by men (70.6%), students (42%), and single people (68.2%). The consumers are mainly Christian (51.7%) or Muslims (35.8%). The principal deciding factors explaining the frequency of individual consumption are age, occupation, and marital status. Four classes of consumers are defined according to the socioprofessional category of the individuals. Garba is highly consumed in 47% of cases, moderately consumed in 35.1% of cases and poorly consumed in 17.9%. Garba is frequently consumed by all sociodemographic levels. Its consumers can be divided into four classes. In view of its high frequency of consumption, a study of its nutritional quality is necessary to ensure guarantee consumer health.

The treatment of cancer, whether a solid tumor or a malignant hemopathy, is accompanied by bouts of infection, the severity and prognosis of which are often correlated to the patient's immune status. In Gabon, where the transmission of Plasmodium falciparum malaria is perennial, the prevalence - around 36% in Libreville - increases in older children and adults. Few authors have described the involvement of this parasite during fever after chemotherapy for hematological malignancies. This work reports three cases of malaria including two severe and one with neutropenia occurring in patients treated for hematological neoplasms.

To study the prevalence and distribution of dermatosis in hospitals and identify factors related to mortality and morbidity due to dermatosis Descriptive and analytical study conducted from 4 years of records of patients hospitalized in the department of dermatology of the University Hospital Center of Brazzaville. We identified 296 files of patients with dermatosis. The M/F ratio was 1.2. Erysipelas and cutaneous drug reactions accounted for 61.1% of the causes. Patients' mean age was 44.3 years. Comorbidity was found in 58.3% of cases. Cardiovascular disease and HIV infection were the most common conditions. The mortality rate was 6.9%. Erysipelas and cutaneous drug reactions are the most frequent dermatoses treated at the University Hospital Center of Brazzaville. Comorbidity exists in more than half the cases. Mortality is high.

Scorpion envenomation is a public health problem in several countries in the tropics and subtropics, with high mortality in the severe forms involving multiple organ failure. The correlation between young age and clinical manifestations of severe scorpion envenomation is well established. We report the case of a 3-month-old infant admitted for severe scorpion envenomation who rapidly developed fatal multiple organ failure, and we discuss the different physiopathological aspects of severe scorpion envenomation.

BACKGROUND Smoking may be a risk factor for marginal bone loss (MBL) and oral mucosal inflammation surrounding dental implants. This retrospective study evaluated the effects of smoking on dental implants in patients with fixed implant-supported prostheses over a period of 36 months following loading. MATERIAL AND METHODS We assessed 120 patients (68 women, 52 men, ages 19-74 years (mean age: 55.10 years) with 315 implants. Implants were classified according to location in the upper and lower jaws and anterior (placed between canines) or posterior (placed between pre-molars and molars) as follows: 1=maxilla anterior, 2=maxilla posterior, 3=mandible anterior, 4=mandible posterior. We also measured MBL, plaque index (PI), sulcus bleeding index (SBI), and probing depth (PD). P-values less than 0.05 were considered statistically significant. RESULTS MBL was statistically greater in smokers (P<0.001) as compared to non-smokers in both jaws. MBL did not vary significantly by location in either group (smokers: p=0.415; non-smokers: p=0.175). Mean PI and PD scores were significantly higher in smokers as compared to non-smokers (P<0.001). A positive correlation was found between PI and PD scores in both groups. No statistically significant difference in SBI was observed between the 2 groups (P>0.05). CONCLUSIONS Smoking was associated with increases in marginal bone loss around implants, independent of their location in the jaws. Also, both plaque indices and probing depths were greater in smokers than in non-smokers.

Blood product suppliers have two options for blood collection: at fixed sites and mobile collection sites. Those preferring voluntary, unpaid donations must move ever closer to the population by organizing mobile collection. The objective of this study was to analyze the impact of mobile collection in the production of the Côte d'Ivoire's CNTS. Our results, based on data from the CNTS from 2014 through 2016 and interviews with 22 managers of blood transfusion centers, confirm the increasing preponderance of this approach. Thus, our results raise the problem of blood safety in a context where the prevalence of transfusion-transmissible infections is higher in mobile collections, where most donors are giving blood for the first time.
