RESUMO
AIM OF THE STUDY: Show the possibilities of diagnosing non - tuberculous mycobacteriosis of the lungs (NTML) in the practice of the pulmonologist. MATERIALS AND METHODS: A survey of 90 patients with a confirmed diagnosis of non - tuberculous mycobacteriosis of the lungs (NTML) was presented. The diagnosis of pulmonary mycobacteriosis was established in accordance with the criteria proposed in 2007 by the American Thoracic Society and the American Society of Infectious Diseases (ATS/IDRS). Among the patients, 55 (61.1%) women prevailed, the average age was 51.2±15.3 years. Patients were evaluated complaints, the presence of concomitant diseases of the lungs, was carried out computed tomography of the chest high - resolution (HRCT), a culture study of sputum, in the absence of sputum or a single determination of the NTM culture in it, a study was conducted on materials of bronchoalveolar washout (ALS/BAL), or lung biopsies. Statistical processing of the research results was performed using descriptive statistics using Microsoft® Excel for Windows xp® on a personal computer. RESULTS AND CONCLUSION: As a result of the study, it was revealed that before the diagnosis of NTML was established, 66.7% of patients were long observed for chronic lung diseases (chronic obstructive pulmonary disease, chronic bronchitis), and in 55.6% of cases (50 people) were registered with a phthisiologist about pulmonary tuberculosis. According to the CT scan of OGK, dissemination was determined in 66.7% of cases, in 48.9% - bronchiectasis, single or multiple destruction cavities - 46.7% of cases. In 72.2% of cases, non - tuberculous mycobacteria (NTM) were found in sputum, in 33.3% - in ALS and in 22.2% of NTMs were found in the surgical material. In 14.4% of cases, only surgery allowed to establish the diagnosis of mycobacteriosis.

OBJECTIVE: to improve the differential diagnosis of disseminated pulmonary tuberculosis (DPT) and exogenous allergic alveolitis (EAA) via comparative investigation of their computed tomography (CT) semiotics and identification of the most informative diagnostic criteria. MATERIAL AND METHODS: 70 patients, including 40 patients with DPT in a phase of infiltration and 30 patients with acute EAA, were studied using a Somatom Emotion 16 multi-slice spiral CT scanner (Siemens). All the patients underwent spiral scanning from the upper chest aperture to the costodiaphragmatic recesses with a high CT algorithm at 0.8-mm slice thickness and a 1.5-mm step. RESULTS: Analysis of the spread of dissemination foci established that pathological changes were peribronchovascularly located in both nosological entities and characterized by a preponderance of septal and intrabronchial locations in DPT and by a centrilobular distribution in EAA. Centrilobular foci were more commonly poorly defined in EAA and mixed foci were observed in DPT. In the latter, peribronchovascular, centrilobular foci were revealed at a distance from the visceral pleura (the boundary of the deep and superficial lymphatic network, respectively) in 38% and more than half of the cases (62%) with the involvement of the visceral and parietal pleura; in EAA, the centrilobular foci were more often combined with the involvement of the visceral pleura in more than 92% of cases. The tree-in-bud sign was significantly more common in DPT. The latter was mostly characterized by apicocaudal regression of dissemination. In EAA, the foci were more frequently located asymmetrically. Monomorphic foci with destruction, as well as their polymorphism were seen in DPT; those without destruction were predominantly observed in EAA. CT ground glass and mosaic perfusion syndromes were significantly more often in EAA. In DPT, the visceral and parietal pleuras were involved in the process in 62% of cases and changes were also more common in the extrapleural fat. CONCLUSION: In addition to the peribronchovascular location of foci, the characteristic CT signs for DPT are a preponderance of intrabronchial and septal locations of foci, their apicocaudal regression, the presence of the CT tree-in-bud sign, and thickened extrapleural fat. EAA showed a prevalence of asymmetrical foci with centrilobular location with the involvement of the visceral pleura into the process, with the presence of CT ground glass and mosaic perfusion syndromes, as well as the bronchial lumen visualized in the peripheral segments of the lung.

The paper describes clinical cases of concomitant lung and intrathoracic lymph node involvements as evidenced by conventional radiography and computed tomography (CT). It shows difficulties in the differential diagnosis of different nosological entities in pulmonary tuberculosis. The x-ray semiotics of concomitant lung injuries is also depicted.

One of the reasons of dramatic situation with tuberculosis in Russia is untimely diagnostics of tuberculosis. The aim of the study was to identify the causes of diagnostic mistakes when we deal with disseminated pulmonary tuberculosis at current stage and to modernize the diagnostic process. The analysis of the diagnostic activity of the consultative diagnostic center of Central Tuberculosis Research Institute of Russian Academy Medical Sciences for 2011 was performed with special attention on the results of the survey of 505 patients with pulmonary dissemination. The frequency of discrepancies of disseminated pulmonary tuberculosis diagnostics was 96.1%. Based on the studies carried out the main causes diagnostic mistakes in patients with disseminated pulmonary tuberculosis were determined. New directions of improving of tuberculosis diagnostics were developed: overall high-technology examination of patient, adherence to the diagnostic procedure, developed by consultative diagnostic center of Central Tuberculosis Research Institute (CTRI), timely performing fiber-optic bronchoscopy with complex biopsy and diagnostic surgery procedures, further training of primary health care doctors. Implementation of proposed activities will significantly (by 3-5 times) reduce the time for diagnostics of respiratory system disease.

Digital versus analogue X-ray studies in identifying different X-ray symptoms are analyzed; their accuracy, sensitivity, and radiation load on a patient were established. The costs of consumables used at digital and analogue X-ray studies have been calculated. An algorithm for monitoring artificial pneumothorax and pneumoperitoneum has been proposed for patients with destructive pulmonary tuberculosis. A procedure has been developed to determine a commissural process in the pleural cavity by digital X-ray study and X-ray computed tomography. The findings are indicative of the expediency and medicoeconomic effectiveness of digital X-ray study used in the monitoring collapse therapy in patients with destructive pulmonary tuberculosis.
