In recent years more data have been obtained on the possibility of performing invasive coronary angiography (CAG) as a method of preoperative assessment of the condition of the coronary arteries. \u0000AIM: To assess the tactics of routine CAG and preventive revascularization of the myocardium in comparison with non-invasive functional tests in patients without clinical manifestations of coronary heart disease (CHD) from positions of the hospital outcomes of AAA resections. \u0000MATERIALS AND METHODS: A retrospective study included 205 patients without clinical and instrumental signs of CHD who underwent AAA resection at National Medical Research Center of Surgery named after A. Vishnevsky in 2001–2021. Patients of the first group (n = 55) underwent CAG before AAA resection and, if significant stenosis of coronary arteries was detected, revascularization of the myocardium was performed. In patients of the second group (n = 71), only functional cardiac tests were conducted before the operation. Patients of the third group were operated on without additional evaluation of cardiac status. \u0000RESULTS: In 30.9% of patients of the first group, significant coronary lesions were detected, in 29.5% of them with the involvement of the left main coronary artery. This required 10 percutaneous coronary interventions and 5 coronary artery bypass surgeries, which made 27.0% of patients in this group. No cases of myocardial infarction were recorded in this group. In the second and third groups, one case of myocardial infarction in each group was recorded (p = 0.688). There was no significant difference in the postoperative mortality in all the groups (1.8%; 4.2%; 2.5%, respectively; p = 0.704). To this end, maximally invasive diagnostic tactics increased the average waiting time for AAA resection: 52.2 ± 6.0 days in groups without coronary angiography and myocardial revascularization versus 99.2 ± 13.0 days in the first group. \u0000CONCLUSION: In a cohort of patients without anamnestic and clinical manifestations of coronary artery disease, the tactics of routine coronary angiography followed by prophylactic myocardial revascularization did not improve the short-term results of AAA resection, while the waiting period for intervention on the abdominal aorta increased.

During treatment and observation of the child, enteral feeding was attempted with pharmacological stimulation with prokinetics, and introduction of laxative sorbent with prebiotic effect (lactulose). Because of non-effectiveness of these measures, it was decided to perform intestinal lavage with OSES introduced through the nasogastral tube. In 30 minites after start of OSES introduction, the gastrointestinal tract motility notably enhanced, in 1.5 hour from the beginning of the procedure, fractional passage of a significant amount of thick fecal masses was noted, after which intestinate — liquid stool stained yellow with bile, was obtained. During the procedure, a comparative analysis of the gas composition of the introduced OSES and excreted intestinate was done. In the excreted solution, 97-fold decrease of рО2 from 659 to 6.8 mm Hg, and 3.6-fold increase in CO2 tension from 23 to 85.7 mm Hg, were noted. \u0000CONCLUSION: Oxygenation of the enteral environment by barbotage of a saline enteral solution introduced through a tube is an effective component of intensive therapy for intestinal failure syndrome, taking into account the ability of the gastrointestinal tract tissues to actively participate in gas exchange: extract oxygen and release carbon dioxide.","PeriodicalId":113364,"journal":{"name":"I.P.

The novelty of the developed Walkbot robot-assisted training system (TS) and insufficient experience of its use in rehabilitation practice require investigations on contingents of patients with musculoskeletal disorders in CP to develop protocols and programs of the rehabilitation use of the Walkbot TS. \u0000AIM: Study of effectiveness of rehabilitation use of the Walkbot robotic TS to restore the walking function in Paralympic athletes with spastic cerebral palsy. \u0000MATERIALS AND METHODS: The study was conducted at the Medical Rehabilitation Center ‘Sergievskie Mineral Waters’ in 2023. Forty Paralympic athletes (all men) aged 30-35 years were examined. The experimental group (EG) and control group (CG) included 20 Paralympic athletes each with standardization of the groups by the main parameters. The classes were conducted for 60 minutes according to the rehabilitation program. In the experimental group, besides exercise therapy (ET), the participants also exercised on the robotic Walkbot TS to restore the walking function, namely, they used Go world game with the known tasks symbolizing counties of the world, Go palace game that permits to take a walk around the palace, when patients move to the right or left as they choose; Go undersea game occurring against the background of a fairy sea world where they must go through the route controlling the direction of movement. The Paralympians of the control group used the standard rehabilitation program including ET with no training and gaming technologies. \u0000RESULTS: The obtained results showed a pronounced improvement in the parameters of motor actions in Paralympians of the EG, while in the CG, positive rehabilitation changes were 2–3 times less expressed. At the initial and final rehabilitation stages, an increase of the tolerated duration of classes was recorded: by 5 times in the EG and 3 times in the CG, post-rehabilitation increase in the EG was 23.4% compared to that in CG. After training on the Walkbot TS, the volume of the performed load increased 5.9 times in the EG and 2.1 times in the CG. The increase in the EG made 64.5% compared to the CG, which indicated an increase in speed-strength qualities and endurance of para-athletes. At the end of rehabilitation, the amount of steps on the Walkbot TS in the EG increased 5.9 times (in the CG — 2.9 times), increase in the EG made 48.3% compared to the CG. \u0000CONCLUSION: The experiment established a complex multisided positive effect of training sessions on the Walkbot TS in the EG versus the effect of only exercise therapy in the CG. The obtained data suggest that training on the Walkbot TS confer a significant restorative and normalizing effect on the neurophysiological mechanisms of functioning of the central parts of the motor cortex.","PeriodicalId":113364,"journal":{"name":"I.P.

Many practitioners note the effectiveness of using intense pulsed light in treatment of rosacea acne. Along with hardware techniques, azelaic acid-based gel is actively used in treatment. Despite the growing popularity of phototherapy, there is insufficient scientific literature on the study of optimal parameters of intense pulsed light for patients using azelaic acid. \u0000AIM: To describe the experience of application of a combination of intense pulsed light and azelaic acid in erythematotelangiectatic subtype of rosacea. \u0000A clinical case of a 52-year-old female patient with severe erythematotelangiectatic rosacea. Phototherapy was conducted in a course of 7 procedures with an interval of 3 weeks; azelaic-based gel was prescribed twice a day for 5 months, sunscreen cream with protection factor 50 for daily use. For the first procedure, a filter with 640 nm wave length was used, fluence 22 J/cm2, pulse duration 3.5 ms, number of subpulses — 3; filter with 590 n wavelength, fluence 22 J/cm2, pulse duration 3.5 ms, number of subpulses — 3; filter with 560 nm wavelength, fluence 20 J/cm2, pulse duration 3.5 ms, number of subpulses — 3; filter with 515 nm wavelength, fluence 16 J/cm2, pulse duration 3.5 ms, number of subpulses — 3. After 3 weeks, a second phototherapy procedure was conducted according to the same protocol. In the third procedure, the energy flow on each filter was increased by 1 J, pulse duration and number of subpulses did not change. On examination in 3 weeks, there was a reduction of the number of small and large telangiectasias, significant reduction of redness, no disturbing subjective sensations. In the subsequent procedures it was decided not to increase the energy flow on filters to avoid recurrent undesired phenomena. \u0000CONCLUSION: Clinical observation demonstrated the effectiveness of using a combination of intense pulsed light and azelaic acid in erythematotelangiectatic rosacea when selecting the maximum permissible parameters of phototherapy.
