[The specific features of detection, clinical picture, and treatment of pulmonary tuberculosis in patients with mental diseases].

One hundred and thirteen patients with pulmonary tuberculosis and mental disease and 127 tuberculosis patients without mental diseases were studied. Patients with mental diseases were observed to have asymptomatic pulmonary tuberculosis with insignificant expectoration, which made the microbiological diagnosis of tuberculosis difficult. The basic method for detection of tuberculosis is to make a fluorographic study every 6 months, which enables active detection of more than 92% of new cases of tuberculosis as minor forms.

[Use of transpedicular fixation in the surgical treatment of tuberculosis spondylitis and chronic hematogenous osteomyelitis of the vertebral column].

The efficiency of applying various posterior instrumental fixation modes (semirigid constructions and transpedicular fixation (TPF)) was comparatively analyzed in 91 patients with tuberculosis and and osteomyelitis of the spine. TPF was shown to have some advantages in correcting its deformity and preventing the latter's losses, reducing the number of complications in the area of anterior spondylodesis.

[Clinical, X-ray, and bacteriological features of drug-resistant tuberculosis].

The data on 1400 patients with first diagnosed drug-resistant tuberculosis, who were followed up in 2000-2005, have been used to analyze the causes of and factors predisposing to the development of clinical, X-ray, and bacteriological features of drug-resistant tuberculosis. The prevalence of its clinical forms with a rapid progression of the process, with complications, comorbidity, the high frequency of multidrug resistance, total resistance, and massiveness and duration of bacterial isolation, which are commonly observed in socially dysadapted patients in incompliance of appropriate treatment regimens, is shown to determine a great epidemic danger. These features should be taken into account on developing and implementing the appropriate measures in both tuberculosis facilities and general hospitals.

[The impact of migratory processes on the epidemiology of tuberculosis in the Stavropol' territory].

Tuberculosis morbidity in the Stavropol territory has recently increased from 31.5 to 43.0 per 100,000.

Use of matrix-modifiers in atomic-absorption determination of chromium in argillites.

The direct atomic-absorption determination of chromium in argillites, without preliminary concentration and separation, has been studied. A map of selective flame zones for determining Cr in argillites has been designed. An express method for determining Cr in Estonian argillites has been suggested.
