[Role of visible irradiation in industrial medicine].

Modern norms regulating illumination levels of working surfaces do not consider changes in functional state of vision. Experimental studies involving examinees helped to set optimal levels of brightness for light entering eyes in complicated visual work. If larger object viewed, brightness of the working surface could be lowered to values that do not decrease visual efficiency. The data obtained enabled to justify allowable brightness levels in accordance with complexity of visual tasks. Regulation of visible light according to brightness values appears to be more adequate for visual functions.

[Smoking among medical students].

A fundamental statistical analysis of the questionnaire given to 2089 first-year and last-year students of 9 medical institutes of the country was carried out within the framework of study of the "Smoking and Health" International Committee. The number of smokers per day was 21.6%. Awareness of smoking association with the development of certain diseases is 2-3 times higher in the last-year students than in the first-year ones. Among the nonsmokers 87.6% supported the need to limit smoking in public places, 79.2% to prohibit tobacco selling to children, 66.6% to prohibit advertisement of tobacco products and 82 supported the idea of instructing doctors in methods for treating smoking. Smokers were less enthusiastic in supporting the proposed measures. Among the smokers 53% claimed failure in giving up smoking. The main responsibility in banning smoking falls on medical profession.

[To differential diagnosis of esophageal cancer and other diseases with the similar clinical symptoms, by using traditional X-ray study].

The principal purpose of the paper is to assess the role of the X-ray section of current radiation diagnosis in obtaining objective information and interpreting it in esophageal cancer. The study was methodically based on its serial studies, by comparing the data of clinical, radiation, and endoscopic diagnosis with those of morphological studies of the biopsy specimens taken at resection for cancer of the esophagus and the upper stomach, and histologically examined them in diseases running with the similar clinical symptoms. The complex of radiation techniques included traditional X-ray study (compact filling, double contrasting). A specially developed procedure that allowed physicians the opportunity to examine the cardioesophageal area in the fragmentary fashion was used during morphological studies. In cancer of the upper stomach, the lower esophageal segments were also involved in the process in 79.9%. It should be also noted that this number of observations includes some cases that clinical symptomatology and endoscopy strongly suggest cancer of the lower third of the esophagus. The authors have arrived at the conclusion that the present-day X-ray semiotics of esophageal diseases running with the similar clinical symptomatology permits their differential diagnosis just before the use of endoscopy and histology of biopsy specimens and that the unique advantage of radiation diagnosis over endoscopy is to specify the initial site of a tumor, namely, to detect primary gastric damage in cardioesophageal carcinoma.

[Potential use of radiation diagnosis of esophageal achalasia].

The prime objective of the paper is to attempt to reevaluate the potentialities of current radiation diagnosis of esophageal achalasia. Moreover, its main idea is to assess the procedure of a traditional X-ray section of radiation study. In the authors' opinion, the main motivation of writing this paper was the emergence of new recent potentialities of radiation diagnosis, including its traditional X-ray section in gastroenterological pathology, as well as a considerable body of information on esophageal achalasia (144 cases). The tasks to be solved in the paper include the differential diagnosis of esophageal achalasia and cardioesophageal cancer, as well as the basic capacities of radiation diagnosis to help clinicians in characterizing the changes caused by medical and surgical treatments for this disease. The authors consider that the obtained volume of necessary information on this abnormality rather frequently encountered in esophagogastroenterological pathology can be increased by applying the current possibilities of radiation study and mainly its traditional X-ray section.
