The drawback with an absorption based CO 2 capture process is the large heat consumption needed for desorption. Different absorption and desorption configurations for 85 % amine based CO 2 removal from a natural gas based power plant have been simulated using Aspen HYSYS. A standard process, split-stream, vapour recompression and different combinations thereof have been simulated. The simulations have been used as a basis for equipment dimensioning, cost estimation and process optimization. Of the evaluated cases, a simple vapour recompression case has been calculated to be the most cost optimum configuration.

Background: The collection of data on cancers is essential to assess their importance in a population and plan control strategies. In Benin as in many sub-Saharan Africa countries, cancer data are often not well informed. Purpose: To study the epidemiological and anatomopathological profiles of head and neck cancers. Methods: This was a descriptive cross-sectional study of head and neck cancers in Benin from January 2009 to 31 December 2014. These tumours were collected in the registers of the 5 anatomy-pathological laboratories in Benin as well as in that of the only hospital in the country that sends its requests for histological examination abroad. Results: During the period, 611 cases of head and neck tumour were reported, including 298 malignant cases, or 48.8%. The average age was 45.3 ± 18.7 years (extremes: 1 year and 91 years) with a maximum of cases between 50 and 60 years (19.1%). The sex ratio was 1.2. The cancers occurred mainly in the pharynx (27.9%), the oral cavity (19.8%), the nose, sinuses and jaws (18.1%), the thyroid (12.8%), the salivary glands (8.7%) and the larynx (8.4%). They were of epithelial origin in 79.5% of cases, mainly squamous cell carcinomas (50.3%) and lymphomas in 12.8% of cases. Conclusion: Head and neck cancer is preventable. A special place should be given to the fight against cancer in Benin. Strategies to prevent and manage these cancers cannot be put in place without accurate data collection.

The prevalence of AR symptoms in Parakou was high. A non-negligible proportion of symptoms were severe. This disease merits special attention in the city.

Introduction : Les topiques auriculaires (TA) sont très utilisés dans le monde en raison de leur remarquable efficacité. L’objectif de cette étude était d’évaluer les connaissances et pratiques des pharmaciens et auxiliaires des officines de pharmacie de la ville de Parakou face aux topiques auriculaires en 2021. Méthode : Il s’est agi d’une étude transversale à visée descriptive et analytique portant sur les pharmaciens et auxiliaires des 19 officines de la ville de Parakou. Les données ont été collectées à l’aide d’une fiche d’enquête du 8 Avril 2021 au 8 Juillet 2021. Résultats : Sur les 129 sujets colligés, les auxiliaires représentaient 86,05% des enquêtés et les pharmaciens (13,95%). La sex-ratio était de 0,32 avec une prédominance féminine. L’âge moyen était de 31,78 ans ±8,52ans. Près de la moitié des enquêtés avaient en majorité moins de 5 ans d’ancienneté (49,61%). La majorité des enquêtés (66,67%) avaient reçu leurs connaissances sur les topiques auriculaires lors de leur formation de base. Les gouttes auriculaires étaient la forme galénique connue de tous (100%). Les antibiotiques étaient la classe thérapeutique la plus connue (97,64 %). Seuls 11,62% des enquêtés avaient une bonne connaissance des topiques auriculaires. Le bon niveau était significativement plus retrouvé chez les pharmaciens comparativement aux auxiliaires de pharmacie (p=0,004). Les topiques auriculaires étaient délivrés hors prescription médicale dans 97,67% des cas. L’automédication représentait 89,92% selon les enquêtés. En cas d’automédication, l’intégrité des tympans n’était pas vérifiée dans 92,80% des cas. La pratique adéquate était retrouvée chez 40,31% des enquêtés.  Conclusion : Cette étude a montré que le niveau de connaissance du personnel de pharmacie sur les topiques auriculaires est insuffisant mais la pratique est adéquate chez 40% des enquêtés.  Des mesures d’information et de sensibilisation sur les topiques auriculaires sont à envisager pour améliorer les niveaux de connaissance et de pratique des pharmaciens et auxiliaires des officines de pharmacie de la ville de Parakou sur les topiques auriculaires.   Introduction: Topical Ear Medication (TEM) is widely used around the world because of its remarkable efficacy. The goal of this study was to assess the knowledge and practices of pharmacists and associate pharmacists with regard to topical ear medication in Parakou city in 2021. Method: This was a descriptive and analytical cross-sectional study on pharmacists and their associates in the 19 pharmacies of Parakou city. Data were collected using a survey form from April 8, 2021 to July 8, 2021. Results: Out of 129 subjects collected, associate pharmacists represented 86.05% of respondents and pharmacists (13.95%). The sex ratio was 0.32 with a female predominance. The average age was 31.78 years ± 8.52 years. Nearly half of the respondents had mostly less than 5 years of seniority (49.61%). The majority of respondents (66.67%) had received their knowledge on topical ear medication during their basic training. Ear drops were the dosage form known to everyone (100%). Antibiotics were the best known therapeutic class (97.64%). Only 11.62% of respondents had a good knowledge of topical ear medication. The good level was found significantly more among pharmacists compared to associate pharmacists (p=0.004). Topical ear medication was delivered without a medical prescription in 97.67% of cases. Self-medication accounted for 89.92% according to respondents. In case of self-medication, the integrity of eardrums was not checked in 92.80% of cases. Adequate practice was found in 40.31% of respondents. Conclusion: It appears from this study that the level of pharmacy staff knowledge on topical ear medication is insufficient but the practice is adequate in 40% of respondents. Measures of sensibilisation should be taken to improve the level of knowledge and practice among pharmacists and their associates on topical ear medication in Parakou city.

Introduction: Acute otitis media (AOM) is one of the most common ENT childhood diseases. Objective: To identify risk factors for AOM in children aged 0 to 5 years. Methods: This research work was a cross-sectional, descriptive and analytical study. It focused on 2040 children aged 0 to 5 years from both sexes, who were healthy or sick, and living in the Local government of Parakou for at least one year. Those children were randomly selected in all three districts of Parakou. Results: Frequency of AOM was 2.8% and their prevalence was estimated at 16.3%. The identified risk factors were persistent or chronic cases of rhinitis, exposure to charcoal and wood smoke, low socioeconomic status, personal history of AOM, AOM history among the siblings, and children's poor nutritional status. No relationship could be established between AOM occurrence and factors like sex, passive smoking, attendance of a day-care centre or stay in nursery, prematurity, exclusive breastfeeding and large number of siblings. Conclusion: The identification of those risk factors will help put in place appropriate measures to reduce AOM prevalence in Parakou.
