Rhinologic signs associated with snuff taking.

OBJECTIVE: To study rhinologic signs associated with nasal tobacco (snuff) intake in Parakou, northern Benin. MATERIALS AND METHODS: A cross-sectional descriptive comparative study included 300 tobacco snuff takers and 300 subjects who did not use tobacco at all. The sampling technique was a stratified 4-stage random sample for non-users and a convenience non-random sample for snuff takers. RESULTS: The sex-ratio was 0.92 in non-users and 41.9 in snuff takers. Duration of snuff taking was more than 20 years in 24.3% of cases. The symptoms studied were significantly more frequent in snuff takers than non-users (P<0.05). Snoring was reported by 58.3% of snuff takers, versus 5.7% of non-users (P=0.000). Nasal obstruction and rhinorrhea were reported by respectively 26.3% and 22.7% of snuff takers, versus 6.3% and 5.3% of non-users (P=0.000). Hyposmia was reported by 14% of snuff takers, versus 1.3% of non-users (P=0.000). Anterior rhinoscopy found abnormalities in 81.7% of snuff takers, compared to 10.67% of non-users. Nasal hypertrichosis was more frequent in snuff takers than non-users: 40% versus 5% (P=0.000). CONCLUSION: Nasal intake of tobacco is responsible for morbidity in snuff takers compared to non-users of tobacco.

[Prevalence and control of asthma among medical students at Parakou, Benin]. / Prévalence et contrôle de l'asthme chez les étudiants en médecine à Parakou, Bénin.

INTRODUCTION: The objective of this study was to determine the prevalence and to assess the control of asthma among students at the faculty of medicine of the university of Parakou in Benin. METHODS: This cross-sectional study was carried out between January and November 2017. The Asthma Screening Questionnaire (ASQ) was filled out by medical students, followed by the Asthma Control Test questionnaire for those who were suspected of having clinical asthma (ASQ≥4). All students with clinical asthma or with a history of asthma were invited to perform a spirometry test. RESULTS: Overall, 837 (73.7%) students out of 1136 were included. The prevalence was 9.1% for ever diagnosed asthma, 14% for clinical asthma and 5.3% for confirmed asthma. Among 761 students, without a previous asthma diagnosis, 10.4% had clinical asthma and 3.3% a confirmed asthma. Female sex (aOR=2.1; 95%CI =1.0-4.1), a previous diagnosis of asthma (aOR=7; 95% CI=3.2-15.2) and allergic rhinitis (aOR=3.9; 95% CI=1.9-7.8) were associated with confirmed asthma. Asthma symptoms were controlled in 92 (78.6%) students, partly controlled in 20 (17.1%), and not controlled in 5 (4.3%). CONCLUSION: Clinical manifestations of asthma are frequent among medical students at Parakou. Some are not well controlled, suggesting a need for greater awareness and an improvement in clinical follow-up.

Symptoms of allergic rhinitis in Parakou, Benin: Prevalence, severity and associated factors.

AIMS: Allergic rhinitis (AR) is an extremely common disease. This study aimed to determine the prevalence and severity of AR symptoms and potential associated factors, in Parakou, a city in Benin. MATERIALS AND METHODS: A cross-sectional study was conducted between April and July 2016, involving inhabitants of the city aged between 6 and 65 years. Cluster sampling was carried out. AR symptoms were defined as the simultaneous presence of rhinorrhea, nasal obstruction and sneezing without evidence of respiratory infection. Data were analyzed on EpiData Analysis v2.2.2.183 and then on R.3.2.1. RESULTS: Three hundred and ninety-five inhabitants were questioned, with a male/female ratio of 1.32, and median age of 19 years. One hundred and forty-one (35.7%) had AR symptoms, 47 (33.3%) had family history of atopy, and 87 (61.7%) had allergic conjunctivitis. The main triggers were house dust (139; 98.5%) and air pollution (111; 78.7%). On multivariate analysis, associated factors were age<18 years (P<0.05), exposure to house dust (P<0.001), and personal history of urticaria (P<0.001) or allergic conjunctivitis (P<0.01). Twenty-eight subjects (19.9%) had persistent symptoms. Forty-three (30.5%) had moderate/severe symptoms, associated with age≥18 years (P<0.01), family history of atopy (P<0.01), personal history of atopic eczema/dermatitis (P<0.01), and presence of a dog or cat at home (P=0.01). CONCLUSION: 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.

Aspects echographiques des glandes parotides chez les personnes vivant avec le VIH (PVVIH) a Parakou (Benin)

Objectif: Decrire les aspects echographiques des glandes parotides chez des sujets infectes par le VIH au Centre Hospitalier Departemental du Borgou (CHD/B). Materiel et methode : Il s'est agi d'une etude transversale descriptive menee du15 janvier au 15 juin 2011. 200 personnes vivant avec le VIH ont beneficie d'une echographie mode B des glandes parotides. Resultats : L'echographie des glandes parotides etait anormale dans 91;5% des cas alors qu'une hypertrophie glandulaire clinique n'etait retrouvee que dans 11% des cas. Le diagnostic echographique portait sur les kystes lympho-epitheliaux (32%); l'agregation lymphocytaire (27%); l'infiltration graisseuse (26%) et les adenomegalies(6;5%). Chez les sujets sous traitement ARV; la prevalence des kystes lympho-epitheliaux etait moindre et celle de l'infiltration graisseuse plus elevee. Conclusion: L'absence de parotidomegalie chez les sujets VIH n'est pas synonyme de normalite et l'echographie reste le moyen ideal pour decrire les lesions parotidiennes que sont les kystes lympho-epitheliaux; l'agregation lymphocytaire l'infiltration graisseuse et les adenomegalies

[Cervicofacial cellulitis of dental origin: etiology, epidemiological and therapeutic aspects]. / Aspects étio-épidémiologiques et thérapeutiques des cellulites cervico-faciales d'origine dentaire.

OBJECTIVES: Cervicofacial cellulitises are dominated by dental affections. The aim of this study is to describe etio-epidemiological and therapeutic aspects of cervicofacial cellulitis of dental cause at the CNHU-HKM in Cotonou (Benin).

RESULTS: 68 cases whose 53 dental cause where been collected 77.94%. Bracket concern patients between 0-20 and 20-40 years old (64.15%). Males were, more concerned. Dental traumatisms find again (18.88%), tooth decay (56.60%) and 24.53% patients practiced dental extraction. Anti inflammatory practiced by 67.92% patients associated to antibiotic in 41.51% cases. The three latest molar were concerned to 26 patients. Among those last 22 had attack of mandibular teeth. Treatment consisted in lancing drainage to 2/3 patients in 83.40% cases associated to tri antibiotic. Evolution has been favourable with recovery to 86.67%; 6 decreases to 13.33% cases. CONCLUSIONS: Cervicofacial cellulitises are dangerous, rapidly responsible of deceases by extension. A better oral and dental hygiene would improved prognosis.
