[Diagnosis of the obstructed pulmonary abscesses].

Only spot bronchography, and if its results are negative, transthoracal puncture permit a correct diagnosis of blocked or partially blocked pulmonary abscess in 2/3 of cases. This result is of importance for the choice of the treatment strategy in such patients. Use of thin or super-thin needles for puncture helped to do without serious complications and obtain reliable diagnostic information in 90% of cases.

[Roentgeno-morphologic forms of bronchioloalveolar cancer].

The paper is concerned with the description of clinical, x-ray and morphological investigation of 123 bronchoalveolar cancer patients. Three types of this disease were defined: nodular (homogeneous and nonhomogeneous), pneumonia-like (infiltrative and infiltrative-nodular) and mixed (focal-disseminated, focal-nodular and focal-infiltrative). These types of bronchoalveolar cancer are most probably stages of the same tumor process.

[Roentgeno-endoscopic diagnosis of elevated early cancer of the stomach].

The authors analysed 27 patients. It is shown that the X-ray and endoscopic methods possess sufficiently high sensitivity in identifying elevated forms of early carcinoma of the stomach (in 90% and 100%, respectively). Their specificity, however, is low because errors of each method come up to about 50%.

[Diagnosis and surgical treatment of a mediastinal form of lymphogranulomatosis].

The article deals with material on 161 patients with the mediastinal form of lymphogranulomatosis. Variants of the X-ray picture and clinical manifestations of the disease are described. The authors list the indications for the use of bioptic methods of examination--prescalene biopsy, transthoracic needle biopsy, transtracheobronchial puncture, and mediastinoscopy.
