Antituberculous fight in the Maghreb: the balance sheet.

The fight against tuberculosis remains a priority for world leaders: a re-emerging disease in developed countries, endemic elsewhere, it was declared in 1993, as a "world emergency" by the World Health Organization (WHO). The aim of programs is to prevent infection from spreading and perpetuating; the recommended strategies were the subject of common consent by expert committees convened by international agencies, primarily the WHO. As a result, programs of the Maghreb countries have great similarities. Though the regression in cases's number, especially primary and post-primary forms, as well as extensive, deleterious pulmonary tuberculosis in adults, the endemic persists. The proportion of extra-pulmonary tuberculosis (PET) is high. Control of "contacts" would be lacking or delayed in almost half of the cases. The cover by an effective treatment of these cases in Libya and in Mauritania stays below the required 85 %. Taken as a whole, the constituent countries of the Maghreb entity count approximately 78 000 tuberculosis patients for a population close to 100 million inhabitants, with an incidence rate of 76 for 100 000. Reducing the incidence of tuberculosis by 90 % and the mortality by 95%, to ensure that by the end of 2035 tuberculosis is no longer a public health problem is a goal within the reach of Maghreb countries. It can be postulated that by this deadline, the conditions for success will be met.

[Health transition in Tunisia over the past 50 years]. / La transition sanitaire en Tunisie au cours des 50 dernières années.

We describe the dramatic demographic, socioeconomic and health changes witnessed in Tunisia over the past 50 years. Demographically, the gross mortality rate and the infant mortality rate have gone from 19 per 1000 and 150 per 1000 respectively in 1956 to 5.7 per 1000 and 26.2 per 1000 now, and life expectancy at birth going from 50 to 72 years for the same period. Socioeconomically, the urban population has risen from 25% to 62%, the literacy rate from 15% to 73%, and the per capita income has increased 5-fold in real terms. Epidemiologically, the infectious and perinatal diseases prevailing in the 1960s have decreased whereas chronic and degenerative diseases have risen. The proportion of the GNP related to health expenditure has risen from 3.8% to 6.2%. The implication of these changes on the Tunisian health system and the need to adapt in terms of curative care and prevention of risks are discussed.

[Ramadan and customs of life: investigation with 84 adult residents in the district of Tunis]. / Ramadan et habitudes de vie: enquete aupres de 84 adultes residant dans le district de Tunis.

To know nature and the dimension of the change of the customs of life leads by the Ramadan, we led a comparative descriptive inquiry before and during the month of the fast at 84 adults residents in the district of Tunis. Our results underline an increase of the consumption of meat and eggs with an average frequency of 4.3 and 6.1 times a week respectively. This overconsumption of the animal proteins contrasts with a tendency in the decline of the consumptions of vegetables. The exciting (tea, coffee, tobacco) are less consumed during the Ramadan. Also, we noted a decline of 50% of the average number of smoked cigarettes. There is an intensification of domestic links with an increase of the frequency of exchange of domestic visits. It's crossed of average from 0.7 to 1.2 times a week (p < 0.001). The phenomenon of irritability is frequently lived by near 20% of the investigated. We recommend under shape of an educational program the intensification of positive customs and the correction of negative customs, to benefit of sacred month, to tighten towards a more balanced life all year.

[Trends in tobacco consumption in Tunisia]. / Tendances de la consommation tabagique en Tunisie.

Because tobacco-related diseases are a growing health problem, we assessed tobacco smoking in Tunisia since 1970 using different sources. The average consumption of tobacco calculated over the period of 10 years (1981-90) was 1493 g per person and per year; equivalent of 75 packets of cigarettes. Cigarettes are the most popular form of tobacco smoking. Cigarette smoking increased from 1981 to 1993 but since has decreased slightly. According to a national study of respiratory diseases conducted in 1996, the current prevalence of tobacco smoking is 30.4% for both sexes: around 52% for males and 6% for females. Average consumption is 17.7 cigarettes/day, irrespective of sex. For young people, the prevalence is 29.21%: 50% for males and 3.9% for females. Young people who attend school smoke less than those who do not (18.1% versus 38.4%). Most started smoking between 14 years and 18 years.

[Reexpansion pulmonary edema]. / Oedèmes pulmonaires à vacuo.

Reexpansion pulmonary edema is an uncommon complication which sometimes occurs after evacuation of a large amount of air or fluid from the pleural space. We report two cases that illustrate the diversity of the clinical expression, severe in one case and latent in the other. The pathophysiology of reexpansion pulmonary edema remains obscure. Increased pulmonary capillary permeability, favored by previous atelectatic parenchyma and rapid reexpansion appears to be the main cause. Treatment is basically preventive. Curative treatment is based on adequate oxygenation and circulation. Lower aspiration pressure and oxygenation were sufficient in our patients. Severe clinical prognosis has been reported in the literature with a 15 to 20% mortality despite use of mechanical ventilation in particularly serious situations.

[Broncho-pulmonary cancer associated with pulmonary tuberculosis. Report of 4 cases]. / Association cancer broncho-pulmonaire et tuberculose pulmonaire. A propos de 4 cas.

The association between bronchopulmonary carcinoma and pulmonary tuberculosis would not be fortuitous but related to increased susceptibility to opportunistic infections and tuberculosis in cancer patients. We present four cases demonstrating the gravity of the situation and the difficulties encountered in diagnosis and treatment. Diagnosis of tuberculosis in patients with bronchopulmonary carcinoma requires pathological evidence from histology biopsies or bacteriology samples. The diagnosis is further complicated in early stage neoplasms. In case of tuberculosis, surgical treatment of bronchopulmonary carcinoma may have to be postponed or even contraindicated. Inversely, chemotherapy and radiotherapy may favor extension of the tuberculosis.

[Smoking among medical students in Tunisia: trends in behavior and attitudes]. / Le tabagisme des étudiants en médecine en Tunisie: tendances des comportements et des attitudes.

We report a cross sectional survey to analyze the effects of medical training on the smoking habits of Tunisian medical students, and their attitudes and knowledge about smoking. Two groups of medical students were studied. One group was 257 first year students at the Medical Faculties of Tunis and Sfax, in 1987, the other 211 final year students at the same Faculties in 1994 and who had been in the first year in 1987. A questionnaire bases on that of the WHO and International Union against Lung Disease for health professionals was administered. It was completed by 95% of the students. Fifty-four % were men and 46% women, and 70.2% lived in an urban area before attending university (table 1). Nonsmokers were defined as those who had never smoked. Exsmokers were those who had formerly smoked but no longer did so. Smokers were divided into those who smoked occasionally and those who smoked daily. The prevalence of smoking was higher among the final year students than the first year students. Combined daily and occasional smoking was 24.1% among first year students and 37.1% among final year students (table 2). The rates among men for daily smoking were 19.2% in the first year and 38.9% in the final year, whereas for women the corresponding rates were 1.8% and 2% (table 3). The prevalence of occasional smoking among men was 17.8% for the first year and 17.7% in the final year. Among women, this behavior increased from 5.5% to 16.8%. Men exsmokers increased from 6.2% to 16.8% and women from 4.6% to 13.4% from the first to the final year. The proportion of first year smokers who reported a serious attempt to stop was 64.8% and that of final year students was 50%. Protected personal health was the most common reason (table 4). In the final year, 94.1% of te students agreed strongly with the view that smoking is harmful to health (table 5). However, there was substantial underestimation of the contribution of tobacco to causing serious diseases including bladder cancer, coronary artery disease, peripheral vascular disease, emphysema and neonatal morality (table 6). The study evidences insufficient awareness of medical students about their responsibility for health education and prevention. There was little interest in preventive action for patients. Only 4.5% of the final year students felt that they were equipped to advise patients about smoking. Similarly, 65.7% would not advise patients to stop smoking if they had no smoking-related symptoms and did not raise the question themselves (table 7). There were major deficiences in knowledge of preventive measures. Only 45.5% of final year students considered that they had adequate knowledge to advise patients about smoking (table 8) and 72.5% thought that they should have received more specific training about counseling (table 9). This work shows that, like in Africa, Asia and Europe, Tunisian medical students have an unsatisfactory knowledge of tobacco and its effects. There were no substantial changes in the students' knowledge of, or attitude to, smoking between the first and final year of training. Simply stimulating the interest of these future doctors in the problem of smoking is insufficient.

[Assessment of the quality of management of arterial hypertension in a public health center (Ariana - Tunisia)]. / Evaluation de la qualité de la prise en charge de l'hypertension artérielle dans un centre de santé de base public (Ariana-Tunis).

The management of hypertensive outpatients in a primary health care center raises problems of follow-up and effectiveness. This study attempts to assess the management of high blood pressure, using the Medical Audit method, essentially. For that purpose, 194 medical records of hypertensive outpatients registered between 1980 and 1986 were studied. More than 80% of these patients were women between the ages of 40 and 70 years. The medical records of these patients were compared to a standard management scale including 68 items devised by cardiologists and general practitioners. Globally, 32% of the items were cardiologists and general practitioners. Globally, 32% of the items were respected during management of the outpatients. The initial check-up was the least followed item (6.9%), but afterwards care of patients improved, giving ratings of: 29% for respect of treatment protocol, and 35% for surveillance of treatment. As concerns treatment effectiveness, only 28% of the patients (n = 36) actually completed the five-year follow-up period. In these patients average blood pressure fell from 193 to 143 mmHg (systolic), and from 113 to 93 mmHg (diastolic), between the beginning of monitoring and the end of the fifth year. The insufficiency of high blood pressure management results not only from a shortage of resources, but also from underuse of existing ones, and the practitioners' lack of information.

[Analysis of different aspects of the health systems in Tunisia]. / Analyse de quelques aspects du système de soins en Tunisie.

The health care system in Tunisia is composed of two sectors, public and private. Given the social and economic development level of the country, it can be said that the hospitals, health centers and workforce devoted to health are not severely limited. However, these structures are under-equipped and finance management is not relevant. The establishment of a National Health Service would render all the system more efficient.
