On 2,995 original culture plates which were positive, 1,561 antibiograms were performed at the C.E.R.P.

The research is based on 1,511 cultures of M. tuberculosis and the population was split into two groups: 1,386 untreated subjects or treated for less than 15 days (primary resistance) and 125 subjects who had already been treated (acquired resistance). Over all the years, primary resistance to at least one drug was 6.9%. Primary resistance to SM was 3.0%, to INH 2.2% and to both 1.4% (the levels of primary resistance to EMB and RMP were practically nil).

Each year, 10 million new cases appear: nearly five million are highly contagious; 95% of these cases come from developing countries. The official notification system currently in force is imperfect but a reckoning of the annual infection risk, from a methodical enquiry into tuberculous disease gives exact information on the size of the problem and its evolutionary time scale in each country. This is the best epidemiological index currently available. The technical problems of the struggle against tubercle are resolved in theory: the selective detection of groups at risk, centered on a network of bacteriology laboratories enables identification of all the sources of infection; chemotherapy, becoming safer and safer, with a duration reduced to 6 or 9 months at the maximum and curing practically 100% of the patients; properly performed BCG vaccination reduces the risk of infantile tuberculosis. Operational problems remain the most serious. The greatest difficulties are seen in countries with the highest prevalence: they are linked to a global shortage of resources but also at times a poor utilisation of the resources available. A concerted international action could render antituberculous drugs and the appropriate sanitary technology to all countries.

Breathing exercises (RE), bronchial drainage and controlled coughing are all part of current techniques in physiotherapy. As problems with the rhythm of breathing are frequently encountered in patients with chronic pulmonary disease, their correction is attempted with KR. In order to acquire a new, more efficient breathing pattern, training in simple every day measures is used (such as talking, reading watching TV, walking, climbing stairs, etc.) or techniques using mechanical devices, including inventive spirometers and magnetometers. With a few exceptions, most of the studies show an immediate objective benefit on blood gases and alveolar ventilation, due to a reduced respiratory rate and increased tidal volume. Although dynamic ventilatory work increases, neither the pulmonary haemodynamics nor energy expenditure are altered as judged by oxygen consumption during RE. The long term results are contradictory and more difficult to interpret. Many studies have noted a clinical and functional improvement with fewer relapses and hospital admissions; these studies often lack adequate controls and the clinical state is not always precisely defined; nor whether associated therapy has been changed or not. Other studies have given negative results, and lately the causes of these failures have been better defined. There is insufficient theoretical and practical training of KR at all medical levels, an absence of uniformity in the KR rehabilitation teams, and treatment courses which are both too few in number and too short in duration. An appreciation of these points of criticism should make for greater objectivity in the future analysis of pulmonary rehabilitation.</p>","PeriodicalId":76480,"journal":{"name":"Revue francaise des maladies respiratoires","volume":"11 4","pages":"525-43"},"PeriodicalIF":0.0,"publicationDate":"1983-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17929664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
