[Laser therapy in a comprehensive treatment of patients with gastroduodenal ulcers]. / Lazerterapiia v kompleksnom lechenii bol'nykh iazvennoi bolezn'iu zheludka i dvenadtsatiperstnoi kishki.

Long-term scarring and frequently recurrent ulcers are often found in patients with concomitant diseases such as ischemic heart disease or diabetes mellitus. Laser therapy may be a good alternative in such patients. Gastroduodenal ulcer sites were exposed to laser radiation (He-Ne and AG lasers ATOLL, VITA-01) in 182 patients. The laser treatment was indicated in the failure of a 3-month previous therapy or resistance to antisecretory and antibacterial drugs. Laser treatment is recommended to perform in specialized gastroenterological clinics for better selection of patients, especially those with gastroduodenal ulcer combined with ischemic heart disease and/or diabetes mellitus.

[The use of the orthostatic test in practical medical flight expertise in civil aviation]. / Ispol'zovanie ortostaticheskoi proby v praktike vrachebno-letnoi ékspertizy v grazhdanskoi aviatsii.

Comparison of results from HDT administered with different techniques showed that 5-10 min in vertical position are enough to adequately evaluate mechanisms of circulation control. By that time hemodynamic shifts get stabilized. More precise assessment of the circulation regulation can be made when HDT is administered from initial supine rather than sitting position. Analysis of the ECG dynamics allows to elicit latent myocardial injuries. The exact quantitative characteristic of orthostatic disturbances makes it possible to give their pathophysiological estimate.

[The role of occupational and social stress in the development of non-ischemic arrhythmia in pilots]. / Rol' professional'nogo i sotsial'nogo stressa v vozniknovenii neishemicheskikh aritmii u pilotov.

In the absence of coronary heart disease and ischemic responses to exercise, many highly skilled pilots have been shown to have arrhythmias of non-ischemic origin. The occupational stress-exercise on a flight trainer reveals such arrhythmias much more frequently than bicycle ergometric exercise. Under social stress, namely during medical- and flying examination which decides if a pilot is professionally fit, 24-hour monitoring in the out- and inpatient settings detects premature+ ventricular contractions of non-ischemic origin in high-grade pilots; the contractions regularly decreasing or ceasing during a true flight. Thus, the social stress in pilots is a stronger arrhythmogenic factor than is the routine occupational stress.
