[Use of native and lyophilized Loewenstein-Jensen's solid media in determining drug resistance on mycobacterium tuberculosis strains].

The results of determination of drug medium depend on both individual cultural properties of the strains tested and the type of the medium used. The composition of a medium is of significance for some strains: the latter grow in any medium and are characterized by the same spectrum of resistance. However, most drug-resistant strains have higher feeding demands which are not fully met on the lyophilized Löwenstein-Jensen medium.

[Clinical aspects and treatment of tuberculosis of respiratory organs in adolescents under present epidemiological conditions].

The paper summarizes the results of clinical observations of 55 teenagers suffering from active respiratory tuberculosis. It defines risk factors for this disease in adolescents. Emphasis is laid on the current pathomorphology and a great variety of clinical types of tuberculosis.

[Cost benefit of detection and treatment patients with tuberculosis in Ivanovo region, Russian Federation].

To execute the tuberculosis control programme in the Ivanovo Region, the authors calculated the cost of detection of a tuberculosis case at patients' referrals to a therapeutical-and-prophylactic institution for medical aid and during prophylactic X-ray fluographic examinations and the cost of tuberculosis cure while treating the patient at a hospital in the intensive treatment phase (2-3 months) and in the outpatient setting or at a day hospital by the intermittent method in the continued treatment phase. The costs calculated were compared with those obtained by early approaches. The cost of detection of a tuberculosis case was 1580.

[Sociomedical aspects of detection and treatment of patients with tuberculosis under present conditions].

By analyzing the present-day tuberculosis epidemiological situation in the country and sociomedical characteristics of new cases, the authors present methods for detecting and treating patients, which are of paramount importance for today. Of the most significance is the need to promptly identify patients with strains on their referral to the general somatic hospitals for complaints by using 3-multiple sputum bacterioscopy for Mycobacterium tuberculosis by the Ziehl-Neelsen method. The vital problem is also to change chemotherapeutical regimens as more severe progressive types of the disease require more active treatment in the first months after detection especially in the cohort of socially disadapted persons.

[Present-day problems of detection and patient treatment with tuberculosis].

The problems of detection and treatment of patients with tuberculosis, which are of paramount importance for today, are presented through the analysis of the tuberculosis epidemic situation in the country and of the sociomedical characteristics of new cases (49% of socially disadapted persons). Of the most significance is the need to promptly identify patients with strains on their referral to the general somatic hospitals for complaints by using 3-multiple sputum bacterioscopy for Mycobacterium tuberculosis by the Ziehl-Neelsen method. The vital problem is also to change chemotherapeutical regimens as more severe progressive types of the disease require more active treatment in the first months after detection especially in the cohort of socially disadapted persons.

[Trends in tuberculosis epidemiology in the Ivanovo Region and its stabilizing measures].

In 1993-1995, tuberculosis morbidity increased from 37.8 per 100,000 inhabitants to 55.7.
