[Quality of "crisis communication" media during the COVID-19 pandemic in the Great Maghreb countries]. / Qualité des supports de communication de crise lors de la pandémie de la COVID-19 au Grand Maghreb.

OBJECTIVE: To objectively assess the quality of "crisis communication" media, during the COVID-19 pandemic, in the three Greater Maghreb countries (Tunisia, Algeria, Morocco). METHODS: A compliance audit for press releases and epidemiological bulletins was analyzed against a quality benchmark, which had been specifically designed by the authors. This framework, made up of five dimensions and 50 items, graded (0/1), was applied by two researchers in preventive medicine. Multiplying the scores by a coefficient of two resulted in a partial score of 20 points for each dimension and a total score of 100 points for the checklist taken as a whole. The quality of the communication media was considered to be good when exceeding the thresholds of 15/20 for the different dimensions and 75/100 for the entire grid. RESULTS: A total of 141 information media were included in this audit (Tunisia: 60; Algeria: 60; Morocco: 21). The overall median quality score for these media was only 56/100 (IIQ: [46-58]), without major variability between countries. The most appreciated dimension was "maintaining the confidence of the population", with an overall median score of 14/20 (12/20 for epidemiological bulletins and 16/20 for press releases). The most poorly rated dimension was "strengthening community participation", with a median score of only 4/20 (6/20 for epidemiological bulletins and 4/20 for press releases). CONCLUSION: The quality of the Maghreb crisis communication media during COVID-19 was insufficient in most of its dimensions and items, particularly from a psychosocial standpoint. Reinforcement of the capacities of communication officers to develop information material and supports during health crises is indispensable and should be considered as an urgent matter.

Epidemiology of scalp ringworms and superficial fungal infections in schools in Mauritania.

INTRODUCTION: Scalp Tinea is the most common mycosis in children and adolescents. The objective of this work was to determine the epidemiological and etiological profile of Scalp Tinea in schoolchildren in Mauritania, during the year 2019. METHODS: This is a descriptive cross-sectional study lasting four months, from May to September 2019, in a sample of schoolchildren from Nouakchott, included following a random survey at three levels, having benefited from a clinical examination, mycological and culture samples. RESULTS: A total of 228 children out of the 434 included (52,5%) were detected as carriers of Scalp Tinea, after fungal culture, i.e. rates of 54% in boys and 46% in girls. The most affected age group was 9-12 years (49%). Public schools were the most affected (37,7%), followed by private schools (32%) and traditional schools (30,3%), (p<0,05). Trichophyton sudanense represented 23,5% (n=102) followed by Trichophyton rubrum (15,4%, n=67) and Microsporum langeronii 8,1% (n=35). The type of habitat, the humidity of the environment and walking with bare feet did not significantly influence the presence of ringworms, unlike overcrowding (sleeping with more than two people). The prevalence of scalp ringworms increased from 1,3% for children sleeping on single beds to 22,8% in children sharing their beds and to 75,9% in students sleeping together on the same bed (p˂0,05). CONCLUSION: The results of this survey, conducted in 2019, confirmed the changes in the epidemiological and ecological trend of the mycological profile of Scalp Tinea, in Mauritania. It is necessary to strengthen these results with the molecular characterization of fungal strains circulating in our country.

Stroke in the Blida region (Algeria) in 2018: Incidence and mortality according to a population-based register.

OBJECTIVE: Establishing the incidence and mortality data for stroke in the Blida region (Algeria) for 2018, through the setting up of a population-based register, was the objective of this study. METHODS: The World Health Organization criteria were used to define the stroke. Cerebral imaging was required to confirm stroke and its hemorrhagic or ischemic mechanism. The target population of the study was inhabitants of the region (wilaya) of Blida (Algeria) aged 25 and over. The ratios of overall incidence and mortality rates and age-specific stroke rates were considered to be relative risk (RR). The Standardized Mortality Ratio (SMR) was the ratio of standardized rates. RESULTS: A total of 828 stroke were reported, 85.1% ischemic and 13.5% hemorrhagic. The first-ever strokes constituted 70.5% of the strokes for which the occurrence was documented. The overall incidence rate of stroke for 2018, regardless of mechanism and occurrence, was estimated at 130.3/100000. The corresponding standardized rate for age was 138.1/100000. The incidence rate among men (143.6/100000) was significantly higher than that of women (116.9/100000): RR = 0.81 (95% CI: 0.71; 0.93). The median age of onset of stroke was 70 years. The case-fatality rate at 28 days was 22.1%. The overall mortality rate was 28.8/100000 while the corresponding standardized rate was 29.9/100000. The standardized mortality rate for men (34.5/100000) was significantly higher than for women (25.3/100000): SMR = 0.73 (95% CI: 0.54; 0.99). CONCLUSION: The setting up of a register for stroke in the Blida region has made it possible to quantify the risk of stroke, occurrence and death, and to alert about the burden of disease attributable to this health problem.

Prevalence of smoking in the Maghreb: a systematic review and meta-analysis.

INTRODUCTION: Tobacco is the leading preventable cause of death in the world and kills up to seven million people each year. Monitoring its prevalence is important for prevention programs. The aim of this work was to summarize the literature on the prevalence of smoking in the Maghreb countries during the past two decades. METHODS: The research was conducted on Medline via Pubmed based on the Mesh terms: «Tobacco Use¼, «Smoking¼ and «Africa, Northern¼. Were included articles reporting the prevalence of current smoking in the general population or a subgroup of the population in one or more Maghreb countries. The extracted data was related to current smoking, its definition, total prevalence and prevalence by sex. RESULTS: About 50 articles were included, the data was mainly from Morocco, Algeria and Tunisia. Two studies reported prevalence among college students in Libya. The highest prevalences in the general population were noted in Tunisia with an overall prevalence, during the period studied, of 25% (95% CI [21% -29%]). This prevalence was 16% (95% CI [14% -18%]) in Morocco and 14% (95% CI [8% -22%]) in Algeria. CONCLUSION: The prevalence reported was generally high, especially in Tunisia, although lower than in developed countries, hence the importance of setting up and strengthening prevention and control measures, mainly among young people.

[Pelvic actinomycosis: Diagnostic and therapeutic aspects]. / Actinomycose pelvienne : aspects diagnostiques et thérapeutiques.

OBJECTIVES: Actinomycosis is a rare little known granulomatous suppurative disease, more common in women, aided by the use of contraceptive purposes intrauterine device (IUD). Pelvic location is the rarest with an extension to adjacent organs making preoperative diagnosis difficult and misleading clinical presentation. Early diagnosis of this affection determines the therapeutic strategy and avoids mutilating interventions especially in young women. METHODS: We reviewed the record of women who consulted the department of obstetrics and gynecology at Ben Arous hospital (Tunisia) between January 2003 and December 2013 for a pelvic pain syndrome and in whom diagnosis of actinomycosis was suspected by clinical and imaging and confirmed by pathology. RESULTS: Eight cases of gynecologic abdominopelvic actinomycosis were diagnosed during the study period. Seven patients were carriers of an intrauterine device, with an average duration of 5 years wearing. Functional signs were essentially pelvic pain and fever. Physical examination of patients mainly showed two clinical presentations: a pelvic tumor syndrome or abdominopelvic and an array of pelvic abscess or pelvic inflammatory disease. Radiological investigations were allowed to suspect the diagnosis of actinomycosis only in one patient, in whom percutaneous biopsy confirmed the histological diagnosis without resorting to a surgical procedure. Operative procedures performed were varied as appropriate. The diagnosis of actinomycosis was made by pathology without any cases of bacterial isolation. All patients received antibiotic treatment with penicillin. The subsequent evolution was favorable. CONCLUSION: The diagnosis of actinomycosis should be considered in any invasive abdominal mass of neoplastic appearance and in case of table of genital infection especially in patients bearing IUD for 5 years or more.

Algerian medical teachers' research output and its determinants during the 2000-2009 decade.

BACKGROUND: Publications are the primary output of scientific research. We conducted a national study to quantify Algerian medical teachers' research output and identify its determinants during the 2000-2009 decade. METHODS: The American Medline database and the French Pascal database were used. A publication was eligible only if the lead author was an Algerian medical teacher (in medicine, pharmacy, or dentistry) working in Algeria. The same questionnaire was completed by cases (teachers who were first authors of an original article during the study period) and randomly selected controls. Logistic regression analysis was used to identify factors related to research output. RESULTS: A total of 79 original articles (42.2% of publications) were retrieved, a quarter of which were listed in Pascal alone. The publication rate was 2.6 original articles per 1000 teachers per year. The journals that published these original articles had a median impact factor of 0.83. The ability to publish an original article was 4.3 times higher if the teacher had undergone training in biostatistics and/or epidemiology (adjusted odds ratio [aOR]=4.31, 95% confidence interval [CI]: 1.79-10.38). A promotion evaluation grid that did not encourage writing (aOR=3.44, 95% CI: 1.42-8.33), a doctoral thesis, seniority, foreign collaboration, and English language proficiency were found to be associated with publication output. CONCLUSIONS: Algerian medical teachers' research output was particularly low. Replacing the current promotion grid with a grid that promotes writing, developing abilities to read and write articles and developing English language proficiency are likely to improve this situation.

[Cardiovascular risk factors among shift workers in company of electricity production in the centre of Tunisia]. / Facteurs de risque cardiovasculaire chez les travailleurs postés d'une centrale de production d'électricité au centre tunisien.

THE PURPOSE OF THE STUDY: The aim of the present study was to investigate relationship between shift work and the cardiovascular risk factors. METHODS: A cross-sectional study was included 330 subjects worked in a company of electricity production in the Centre of Tunisia. The collection of data was based on a questionnaire, a clinical exam and biomarkers. RESULTS: A total of 290 workers was participated in our study (128 shift workers and 162 daytime workers). A raised prevalence but not statistically significant of some factors of cardiovascular risks was found in the shift workers: obesity (25.8 % versus 17.9 %), smoking (44.5 % versus 39.5 %), impaired fasting glucose (11.7 % versus 9.9 %), hypertriglyceridemia (28.1 % versus 25.9 %) and hypercholesterolemia (14.8 % versus 12.4 %). Whereas the prevalence of the alcohol consumption (25.8 % versus 16.0 %) was significantly higher in the shift workers (p=0.04). CONCLUSION: The high prevalence of the cardiovascular risk factors, observed in our shift workers, justify the adoption of measures to protect this category of workers.

[Effect of polymorphisms on key enzymes in homocysteine metabolism, on plasma homocysteine level and on coronary artery-disease risk in a Tunisian population]. / Effet des polymorphismes des enzymes clés du métabolisme de l'homocystéine sur l'homocystéinémie et le risque coronarien chez une population tunisienne.

BACKGROUND: Hyperhomocysteinemia is known as an independent-risk factor for coronary-artery disease (CAD). However, the effect of homocystein metabolic enzymes polymorphisms on CAD is still controversed. We investigated the relation between homocystein metabolic key enzymes polymorphisms, homocystenemia and coronary stenosis in a Tunisian population. METHODS: Samples were collected from 251 CAD patients documented by angiography. Genotyping were performed for C677T methylene-tetrahydrofolate reductase (MTHFR), A2756G methionine-synthase (MS) and 844ins 68 cystathionine-beta-synthase (CBS). We measured fasting plasma tHcy, folate and vitamin B12. RESULTS: There was significant increase in homocysteinemia for homozygous genotypes of C677T MTHFR (p<0.001) and A2756G MS (p=0.01), but not for 844ins68 CBS (p=0.105). Potential confounders adjusted odds-ratios for significant coronary stenosis, associated with MTHFR TT, MS GG and CBS insertion, were respectively 1.78 (p=0.041); 2.33 (p=0.036) and 0.87 (p=0.823). The effect of mutated MTHFR genotype was more pronounced on homocysteinemia (21.4+/-9.1 micromol/L; p<0.001) and coronary stenosis (OR=2.73; p=0.033) at low folatemia (< or =6.1 ng/mL). CONCLUSION: MTHFR TT and MS GG genotypes increase tHcy concentration and coronary stenosis risk, especially with low folatemia.

[Attitudes of teachers to tobacco smoking]. / Attitudes des enseignants à l'égard du tabagisme.

We aimed to evaluate the attitudes of teachers to tobacco smoking in Kalaa Kebira (a semi-urban region in the Tunisian Sahel). Data from 358 of 402 teachers surveyed were obtained using a self-completed questionnaire. The mean age of the teachers was 35.7 (SD 7.9) years. The prevalence of smoking was 29.3% (51.6% of men and 3.6% of women), and 79% of smokers were addicted to nicotine according to the Fagerström test. About 50% of the teachers were badly-informed about the dangers of smoking and 75.2% of smoking teachers did not refrain from smoking in front of their pupils. The lack of knowledge of teachers limits their role as a model and information source in the anti-tobacco struggle. It is essential to draw up an education programme for the teaching staff.

[Predictors of increased cardiovascular risk in hypertensive patients in frontline facilities in Sousse, Tunisia]. / Facteurs prédictifs du haut risque cardio-vasculaire chez les patients hypertendus suivis en premiere ligne à Sousse (Tunisie).

We assessed cardiovascular risk factors among 456 hypertensive patients in 7 health centres in Sousse. Cardiovascular risk was estimated according World Health Organization recommendations. Mean age was 65.6 (SD = 9.8) years, male:female sex ratio was 0.18. Cardiovascular risk was not influenced by sex, age or residence. However, patients with longer duration of hypertension and more frequent co-morbidity had a significantly higher cardiovascular risk. In addition 45.9% of patients on monotherapy had high cardiovascular risk compared with 40.6% of those treated with 2 or more drugs (P = 0.02). Non-compliance was not found to be associated with high risk.

[Knowledge of patients with type 2 diabetes about their condition in Sousse, Tunisia]. / Connaissances des patients diabétiques de type 2 sur leur maladie à Sousse (Tunisie).

We assessed the knowledge of 404 type 2 diabetic patients about their condition in order to evaluate the quality of diabetes education in primary health care units in Sousse in 2003. We found that knowledge was satisfactory in only 59% of the patients. Their knowledge about the definition of diabetes and its pathophysiology were the 2 main areas where knowledge was lacking: the proportion of correct answers were 62.6% and 50.3% respectively. More attention should be paid to educating diabetic patients within the chronic disease care national programme.

[Dermatological problems of musicians: a prospective study in musical students]. / Dermatoses des musiciens: étude prospective chez des étudiants en musique.

INTRODUCTION: Musicians are at risk of developing particular skin conditions related to their activity. The purpose of our work was to determine the frequency, describe the clinical aspects and identify the risk factors of specific dermatological problems in musical students. POPULATION AND METHODS: We carried out a prospective epidemiological study between April 2003 and April 2004 among music students registered in four musical institutes of Tunisia. The musicians were questioned and examined in systematic fashion at their institutes. Demographic data, characteristics of instrumental practice and dermatologic manifestations were collected. Five hundred and ninety-four students were examined. The sex-ratio was 1.6 with a mean age of 22.0 +/- 4.0 years. The statistical analysis was performed using SPSS software for Windows (version 12.0). RESULTS: Two hundred and ninety-five students (49.7%) had at least one dermatologic lesion. In multivariate analysis, the following factors were significantly correlated with dermatological problems: male gender, age > or = 20 years, history of musical activity > or = 5 years, practice > or = 10 hours/week and percussion instruments. Nine types of lesions were determined: corns and calluses, pigmentation abnormalities, irritant contact dermatitis, mechanical acne, erythema, friction bulla, nail diseases, cicatricial alopecia and allergic contact dermatitis. Corns and calluses were significantly the most frequent (P<0.001). DISCUSSION: The frequency of dermatological lesions was high compared to data reported in the literature, 20 and 32% respectively in the studies by Onder and Rimmer. This difference could be due to the greater number of percussionists in our study.

[Predictive factors of glycemic control in patients with type 2 diabetes mellitus in primary health care]. / Facteurs déterminants du contrôle glycémique des patients diabétiques de type 2 suivis en première ligne.

PURPOSE: To determine the factors associated with poor glycemic control in type 2 diabetic patients followed in primary care units in Sousse, Tunisia. METHODS: A cross-sectional study was conducted on a representative sample of type 2 diabetic patients followed at least two years in primary health care units in Sousse, Tunisia. Data were gathered from three sources: a self-administrated questionnaire, analysis of patient files and HbA1c level. HbA1c level was measured with turbidimetric immunoinhibition assay. Patients were considered well-controlled if glycated hemoglobin (HbA1c) was less than 7%, according to the American Diabetics Association (ADA) recommendations. RESULTS: The study enrolled 404 type 2 diabetic patients. The mean age was 60.5+/-10.89 years, sex-ratio was 0.5, and mean disease duration 8.7+/-6.1 years. ADA recommendations were met by 16.7% of patients. Multivariate analysis using variables in relation with the patient, his/her family, the disease, the treatment and the health care unit, showed that only poor geographic access to the care center (adjusted OR: 1.89, p=0.009) and Body Mass Index (BMI) less than 30 kg/m2 (adjusted OR: 2.21, p=0.034) were significantly and independently associated with poor glycemic control. CONCLUSION: Glycemic control in type 2 diabetic patients is poor. It depends strongly on geographic access to health care. Type 2 diabetic patients should be referred, as much as possible, to the nearest health care unit.

[Tobacco use among teachers in a district of the Tunisian Sahel]. / Le tabagisme des enseignants dans une commune du Sahel Tunisien.

INTRODUCTION: The aim of this study was to evaluate the scale of tobacco use among teachers in the district of Kalaa Kebira (a semi-urban region in the Tunisian Sahel). METHODS: The study design was descriptive and cross sectional, employing a self administered questionnaire given to 402 teachers. RESULTS: The response rate was 89%. The average age of respondents was 35.7 7.9 years. The global prevalence of smoking among teachers was 29.3% (men: 51.6%; women: 3.6%). 79% of smokers were addicted to nicotine according to the Fagerstrôm test. Half of the teachers were poorly informed about the hazards of smoking and 77.9% of smoking teachers didn't refrain from smoking in front of their pupils. CONCLUSIONS: The teachers' lack of knowledge limits their effectiveness both as a role model and information relay in the war against tobacco.

[Haematological characteristics, FAB and WHO classification of 153 cases of myeloid acute leukaemia in Tunisia]. / Caractéristiques hématologiques et classification FAB et OMS de 153 cas de leucémies aiguës myéloïdes en Tunisie.

A complete blood analysis with a careful morphologic examination of peripheral blood and bone morrow smears completed by cytochemical reaction will help to classify the most acute myeloid leukaemia (AML). Actually, the study of other cytogenetis and immunophenotypic markers are now necessary to confirm diagnosis. The World Health Organisation WHO classification (2001) incorporates theses approaches. The purpose of this study is a bio-clinical review according to the WHO recommendations in 153 cases of LAM diagnosed between January 1998 and December 2003. The patients were aged 2 months to 90 years with sex ratio (M/F) of 1,22. The morphologic conclusion was difficult in 12% cases. Presence of dysplasia is noted in 50% of cases with multilineage dysplasia in 42% of cases. Our results showed cloned chromosomal abnormalities in 57% of cases (t(8;21): 12%, t(15;17) : 10%, Inv16: 1,3%, 11q23: 2,6% et complex karyotype: 14,3%). In 69% of cases with multilineage dysplasia, the karyotype was normal. 3 cases of LAM were noted at patients treated for breast cancer with chirurgic chemotherapy and radiotherapy 3, 4 et 5 years after treatment (LAM3 with t(15;17), LAM4 with genetic abnormalities of chromosomes 3, 5, 7, 8, 9, 14 et 16 et LAM 6 with genetic abnormalities of chromosomes 4, 7, 12, 14, 19 et 21). In WHO classification, cytology is essential in diagnosis of LAM even if the karytype have an important prognostic value. Research of signs of dysplasia lineage after lineage constitutes an important microscopic work and it is difficult to quantify dysplasia when the lineage is poor.

[Diagnostic value of serum and pleural fluid adenosine deaminase activity in tuberculous pleurisy]. / Valeur diagnostique de l'activité de l'adénosine désaminase pleurale et sérique dans la pleurésie tuberculeuse.

The biological diagnosis of tuberculous pleurisy poses the problem of the time required to obtain results and of the sensitivity of the usual diagnostic methods. The determination of adenosine deaminase (ADA) activity has been proposed for the diagnosis of tuberculous pleural effusion and for the follow-up. In the present study, ADA in pleural effusion (p-ADA) and in serum (s-ADA) has been measured in 2 groups of patients: tuberculosis (27) and non-tuberculosis (53) patients. The upper limit of the normal values was fixed at 37 U/L. Comparing these 2 groups, we observed a specificity of 81.2% and a sensitivity of 66.6%. The PPV and the NPV were respectively 64.3% and 82.7%. We used p-ADA/s-ADA ratio for diagnosis of tuberculous pleural effusion, a threshold value of 1.8 gave a sensitivity of 82.6% and a specificity of 84.8%. Within the tuberculosis patient group, the activity of ADA decreased after the appropriate treatment initiation. Thus, the determination of ADA activity and/ or the p-ADA/s-ADA ratio, can help to recognize the tuberculosis origin of pleural effusions.

Medical students and tobacco in 2004: a survey in Sousse, Tunisia.

OBJECTIVE: To assess the behaviour, knowledge and attitudes towards smoking among medical students in Sousse, Tunisia. DESIGN: A cross-sectional survey in classroom settings using a self-administered questionnaire was conducted at the School of Medicine during September 2004. RESULTS: The numbers of students who entered the first and the fifth years of medical training at the University of Sousse in 2004 and completed the questionnaire were respectively 120 and 110. The population age ranged from 18 to 21 years (mean 19 +/- 0.62 years) in first year students and from 22 to 30 years (mean 23 +/- 1.38 years) in fifth year students. The prevalence of daily smoking (both sexes combined) was 4.5% among first year students and 16.7% among final year students. The prevalence of daily smoking according to sex was 29.6% among boys and 0.7% among girls. Over 90% of students thought smoking was harmful to health, but there was considerable underestimation of its causal role in a number of diseases, notably coronary heart disease, bladder cancer and peripheral vascular disease. There were important defects in both knowledge and motivation regarding counselling patients to stop smoking. CONCLUSIONS: The results of this study may provide baseline data to develop an anti-smoking programme in the university.
