[Complex radiologic diagnosis of renal tuberculosis].

The paper analyzes a complex of physical, laboratory, and radiation studies in 71 patients with renal tuberculosis verified by the bacteriological urine test for Mycobacterium tuberculosis (MT) or postoperative histology. Ultrasound study, computed tomography, and excretory urotomography are not shown to be of informative value in diagnosing parenchymatous tuberculosis of the kidney. The diagnosis of this form of tuberculosis is made only on its clinical manifestations and positive urinary MT test. In all other forms of renal tuberculosis and its sequels, pathological changes can be detected on the basis of complex radiation techniques.

[Osteoporotic fracture of the vertebral body in patients with steroid dependent bronchial asthma].

The aim of the study was an analysis of the frequency of oral steroids prescription to patients with bronchial asthma treated in hospital and of vertebral fractures and deformations as the result of GCS-induced osteoporosis in patients with bronchial asthma taking prednisolone tablets for at least 6 months. The incidence of steroid-dependent bronchial asthma (SDBA) was 12.9%. Roentgenomorphometric analysis of the thoracic and lumbar spine performed in 52 patients with SDBA revealed vertebral fractures in 11(21.1%) patients, deformations of the first and second degree in 25(48.0%) patients. Depressed fractures of the vertebra were the most numerous--14.6%. Males and females had vertebral fractures with similar frequency (21.4 and 20%, respectively). A correlation was found between the number of the affected vertebra and prednisolone treatment duration, total dose.

[Differential diagnosis of lobar (regional, segmental) extent pulmonary tuberculosis].

Two hundred and fifteen patients with pulmonary involvement of lobar (regional, segmental) extent were examined. The examination procedure included clinical and laboratory tests, X-ray tomographic study, and computed tomography, bronchoscopy with biopsy, cyto- and histological studies. The nosological diagnosis was established in 96.5% of cases. Differential diagnosis was found to be difficult in 3.5% of cases.

[X-ray longitudinal and computed tomography in the diagnosis of peripheral tumor-like formations of the lungs].

Fifty eight patients with peripheral tumor-like formations of the lung (33 with cancer and 25 with benign formations) were examined by longitudinal tomography and CT. The potentialities of the two techniques in detecting the major semeiotic signs of cancer and malignant formations were compared. The main or major signs, such as the shape of shadow and the pattern of outlines, which make it possible to differentiate benign and malignant formations, are virtually equally imaged by the two techniques. CT is superior to X-ray longitudinal tomography in revealing minor calcifications and microdestructions, hyperplastic intrathoracic lymph nodes. The significance of some symptoms for differential diagnosis calls for further clarification.
