sweeteners and flavor enhancers are food additives widely used in industry, respectively, to add sweetness and flavor to foods. However, the presence of these substances is often criticized by consumers for their effects on health. What’s more, some scientific studies link these substances to certain pathologies. To guarantee food safety, competent authorities should have food standards based on risk analysis using consistent, reliable data. However, in developing countries, such data is often weak or non-existent. The aim of this study is therefore to carry out a pilot survey to establish the profile of sweeteners and flavour enhancers present in industrial food products marketed in senegal. The methodology consisted of sampling various food products sold on the senegalese market, based on analysis of labels containing information on ingredients, including additives. The investigation involved nine stores, one supermarket and 5 mini-markets in Dakar. The results showed the presence of 6 taste enhancers in food products, the most frequent being sodium L-monoglutamate (E621), inosinate (E631) and disodium guanylate (E627). solid broths are the foodstuffs with the highest number of taste exhalters. As for sweeteners, 12 substances were identified, the most frequent being acesulfame potassium (E950), aspartame (E951), sucralose (E955) and saccharin (E954). Given the potential health risks associated with the consumption of these food additives, their control and monitoring on the market should be a priority for the competent authorities.

Food colorants are widely used in the food industry to maintain or enhance product color. However, as the use of these colorants can have negative impacts on health, it is essential to analyze the risks associated with their consumption. This analysis requires, among other things, obtaining sufficient data on the presence of these colorants in foods, as well as their level of consumption. However, data on these colorants is often virtually non-existent in developing countries. The aim of this study was to determine the colorant profile of industrial products marketed in senegal. Information on food additives was collected on 399 labels of different food product categories in shops located in Dakar. Data is recorded and processed using Excel software. Based on the Codex classification, analysis of the profile of additives identified on the labels of food samples revealed the presence of 31 colorants. The natural colorants identified are dominated by beta-carotene, widely present in beverages and dairy products, and paprika extract identified on cookies and industrial sauces. Artificial colors are dominated caramels present in several foods including bouillons, vinegars, sauces and hard candies. secondly, there was a strong presence of the azo dye sunset yellow FCF, widely found in samples of beverages, confectionery and cookies. The results of this case study enable us to appreciate the wide presence and diversity of colorants on the senegalese market, and the importance of controlling them to guarantee consumer safety.

Introduction: Covid-19 is a systemic disease that can spread to all systems. Among the gastrointestinal manifestations, pancreatic involvement can have a major prognostic impact. We report 3 acute pancreatitis cases occurring during Covid-19, in Dakar. Case 1: 65-year-old woman who presented with intense atypical epigastric pain. Physical examination revealed obesity, high blood pressure and abdominal tenderness. Biological tests found increase CRP (134 mg/l) and lipasemia (312 UI/l). Abdominal CT scan showed findings of Balthazar grade C acute pancreatitis. RT-PCR for sARs CoV 2 RT-PCR was positive. The outcome was favorable. Case 2: 56-year-old woman patient with history of nephroangiosclerosis who presented with dyspnea, cough, fever and moderate epigastric pain. Physical examination revealed epigastric tenderness, high blood pressure, anuria. Biological testing, noted increase CRP (96 mg/l), lipasemia (793 UI/l), creatinine (227 mg/l) and urea (3.84 g/l). Abdominal CT scan showed acute edematous pancreatitis findings. sARs CoV 2 RT PCR was positive. The outcome was favorable. Case 3: 27-year-old man who presented with physical asthenia, headache, and epigastric pain. Physical examination found epigastric tenderness. Elevated CRP level was of 102 mg/l and lipasemia level was of 427 UI/l (7N). Abdominal CT scan showed acute edematous pancreatitis findings. sARs CoV 2 RT PCR was positive. The outcome was favorable. Conclusion: Acute pancreatitis can occur during Covid-19 infection. However, the imputability to the Covid-19 disease necessitates to rule out the most common causes.

strong>Background:strong> Portal thrombosis (PT) is a rare pathology. Its prevalence is estimated at 1%. Its consequences depend on the acute or chronic nature, the extent of the clot and the etiology. In Sub-Saharan Africa, very few studies have been devoted to it. Patients and Method: The objective of our work was to determine the prevalence of PT and to describe its clinical and etiological presentation as well as its therapeutic management in the Hepato-gastroenterology department of the Aristide Le Dantec hospital in Dakar. This was a retrospective, longitudinal and descriptive study during the period from January 1, 2012, to December 31, 2018. It included all patients followed in ambulatory or inpatient, who presented a PT objectively determined by a medical imaging examination (ultrasound and/or CT scan). Age, gender, clinical and radiological aspects, proposed treatments and etiology of PT were collected. Results: We collected 71 observations. The prevalence of PT was 1.9%. The mean age of the patients was 41 years 15 and 75 years. A predominance of men was found with a sex ratio of 2.73. The clinical manifestations were dominated by abdominal pain (74.6%), ascites (35.7%) and gastrointestinal bleeding (25.4%). Imaging allowed the diagnosis to be made in 50 patients on ultrasound and 21 patients on abdominal CT scan. PT was acute in 5 patients and chronic in 66 patients. Thrombosis was complete in 71.4% of cases and extended to the spleno-mesaraic venous trunk and the superior mesenteric vein in 2.8% and 8.4% respectively. Etiological research found cirrhosis complicated by hepatocellular carcinoma in 67.6% of cases, cirrhosis with cruoric thrombosis in 21.1% of cases, a combined protein C and s deficiency in 1.4% of cases. No aetiology was objectified in 9.9% of cases. Treatment with beta-blockers was initiated in 32 patients. Anticoagulant treatment was performed in one patient. Evo
