[Hospital Management of Work-related injuries in informal sector: case of artisanal fishing in Saint-Louis (Senegal)]. / Prise en Charge Hospitalière des accidents de Travail dans le secteur informel : cas de la pêche artisanale à Saint-Louis (Sénégal).

OBJECTIVES: to determine the mechanisms, lesions and hospital management of work-related accidentduringtraditional fishing,an activity subject to vital occupational risks. MATERIALS AND METHODS: Descriptive retrospective study on occupational injury files in artisanal fishing professions, registered at the Saint-Louis Regional Hospital (Senegal), from January 2014 to December 2019. All complete records of trauma during any activity related to artisanal fishingwereincluded. Data on accident mechanisms, injuries observed, and hospital management were collected. RESULTS: 47 male workers were on average 28.4 years old. Direct shock from a pirogue was most frequent (68.10%), followed by sharp or blunt objects (16.27%). The lesions were characterized by bone fractures in 63.83% of cases (n=30); chest-abdominal-pelvic and limb contusions and wounds represented 12.67% and 21.27% of cases, respectively. Medical management was done in 21 cases (44.7%). Surgery was dominated by intramedullary nailing in 15 cases (31.9%). Two laparotomies were performed with intestinal sutures. A chest contusion death was reported. CONCLUSION: Traumatic occupational risks in traditional fishing are life threatening. A better understanding of these risks and their consequencesmakes it possible to ensure good prevention.

Factors Associated with Foot Lesions in Diabetic Patients at Saint-Louis Hospital (Senegal): A Case-Control Study Protocol.

INTRODUCTION: Diabetes prevalence has increased over the past years. In Senegal, this prevalence is 4% in the general population. However, the region of Saint-Louis (in the north of the country) has the highest rate with 10.4%. The main prognosis problem is the occurrence foot lesions that can lead to lower-limbs amputation. Diabetic foot is a real public health issue, due to its economic burden and its serious repercussions on patients, leading to poor quality of life. The objective of this case-control study is to identify factors associated with foot lesions in diabetic patients. METHODS AND ANALYSIS: It will be a case-control study from January to December 2021. The patients will be recruited from the departments of general surgery, internal medicine, and emergency. An univariate then multivariate analysis (logistic regression) will allow us to select the variables associated with foot lesions in our study population. The parameters included in the logistic regression will be those with a p < 0.20 in the univariate analysis. Finally, a binary logistic regression analysis (with the calculation of Odds Ratios (OR) with confidence intervals (CI)) according to the backward stepwise method will identify the factors independently associated to foot lesions in diabetic patients. ETHICS AND DISSEMINATION: This research protocol will be submitted to the Ethics Committee of our institution for approval. The knowledge of factors causing diabetic foot will help to communicate with policymakers to raise the awareness in our community. Finally, it will help to prevent lower limb amputations. HIGHLIGHTS: Diabetes is the leading cause of non-traumatic lower-limb amputation in the world.The region of Saint-Louis (Senegal) has the highest prevalence of diabetes.Controlling factors associated with foot lesions in diabetic patients can prevent from amputation.

Profile of Patients with Gallstone Disease in a Sub-Saharan African General Surgery Department: A Retrospective Cohort Study Protocol.

INTRODUCTION: Gallstone disease is a disorder characterised by the formation of stones in the biliary tract. It is the most common biliary condition accounting for more than 98% of all gallbladder and biliary tract disorders. In Africa, previous studies have shown a relative rarity of this condition with a prevalence less than 5%; since it is between 2 and 5 times higher in other continents. A good knowledge of the profile of patient with gallstone disease in a surgical setting could allow to reduce gallstone disease complications and to tailor better the treatment. To our knowledge, there was no previous study about gallstone disease in this region even if there is a high prevalence of metabolic factors of gallstone disease. METHODS: This study objective is to describe the epidemiological, diagnostic and therapeutic profile of patients with gallstone disease at the Department of General Surgery of Saint-Louis Hospital (Senegal). It will be a single-centre retrospective cohort study in a period of 5 years (January 2015 - December 2020). The patients' record of the department of general surgery will be consulted and the patient contacted if there are missing data. Patients with gallstone disease diagnosed with imaging (ultrasonography and/or CT scan) regardless the presentation (asymptomatic, biliary colic, cholecystitis, common bile duct lithiasis, angio-cholitis, pancreatitis) will be included. Adults and paediatric patients will be enrolled. Patient records lacking sufficient data will be excluded. Studied parameters will be epidemiological, clinical, paraclinical and therapeutic aspects. ETHICS AND DISSEMINATION: Anonymity and confidentiality of information collected in patients will be respected. This research protocol will be submitted to the Ethics Committee of our institution for approval. The knowledge of the profile of patients with gallstone disease in a surgical setting could allow to reduce gallstone disease complications and to tailor better the treatment. Finally, it will help to reduce the burden of gallstone disease. HIGHLIGHTS: Gallstone disease is the most common biliary tract conditionTo our knowledge, there was no previous study about gallstone disease in this region even if there is a high prevalence of risk factors of gallstone disease (sickle cell disease, diabetes, obesity, hypercholesterolemia)Good knowledge of the profile of patients with gallstone disease in a surgical setting could allow to reduce gallstone disease complications and to tailor better the treatment.

The epidemiology of nematode infections in sheep in a cool tropical environment.

The epidemiology of nematode infections in Menz sheep was studied in the highlands of Ethiopia at the International Livestock Research Institute (ILRI), Debre Berhan Research Station, using a series of tracer lambs grazing contaminated pasture for either 4, 16, 32 or 48 weeks from July 1992 to June 1994. The basic nematode seasonal infectivity pattern was expressed in terms of relative numbers of third-stage larvae (L3) available on pasture for different months. Data from faecal nematode egg counts, pasture larval recoveries and worm counts from the tracer lambs were used to investigate the infectivity pattern. Four nematode species of economic importance: Longistrongylus (Pseudomarshallagia) elongata, Trichostronglylus colubriformis, Haemonchus contortus, and Dictyocaulus filaria, were recovered from sheep. The largest numbers were recovered during the wet season (i.e. July to November) with peaks in late August and early September. During this 2 year study period, the seasonal pattern of sheep gastrointestinal nematodes was clearly defined. An important finding was that conditions during the short rainy season (i.e. March-May) were not conducive to the development and survival of nematode eggs and the free-living stages, hence little or no transmission occurred. Rainfall and humidity seemed to be the most important factors for the development of eggs and free-living stages. The period of acquisition of third-stage larvae from pasture was found to be relatively short, suggesting that a strategic control programme is feasible with minimal anthelmintic use. Results from the studies are discussed in relation to control strategies.

[Intestinal parasitic diseases and tinea of the scalp in Dakar school population: influence of environmental factors on the infestation level]. / Parasitoses intestinales et teignes du cuir chevelu en milieu scolaire dakarois: influence des facteurs environnementaux sur les niveaux d'infestation.

We carried out a study during February 1993 in a french and three coranic schools in order to evaluate the incidence of the economical level on the prevalence of intestinal parasites and tinea's scalp. Infection rate by intestinal parasites were 67.4% and 84% respectively in french and coranic schools with significant differences: X2 = 10.8. Infection rate by dermatophytes were 10.6% and 48.8% respectively in francophone and coranic schools with significant differences: X2 = 29.3. Ascaris was predominant through all ages in coranic schools, while amaeba were the main parasites in the upper ages in the french school. Bad environmental features observed in coranic schools as well as in popular areas are risk factors to the infection and contribute to increase the prevalence of intestinal parasitic diseases and tinea's scalp.

[Fungi in the hospital environment and infectious risk]. / Environnement fongique hospitalier et risques infectieux.

Using petridishes at hospital in services with risk patients, we have isolated Aspergillus (41.5%), Penicillium (26.4%), Candida (12.2%), Fusarium (7.5%), Mucorales (5%), Scopulariopsis (5%), Scytalidium (0.8%), Tricothecium (0.8%), Ulocladium (0.8%). Several fungi grew at 37 degrees. These saprophytic fungi could give opportunistic mycoses in immunodeficient patients.
