COMPLEX ASSESSMENT OF RIGHT VENTRICULAR FUNCTION IN PATIENTS WITH MULTIVASCULAR CORONARY artery LESIONS
Abstract
Aim. To carry out complex assessment of the right ventricular function in patients with multivascular coronary lesions. Materials and methods. Sixty three patients aged 58,5 ± 9 years including 46 men (73 %) with multivascular coronary lesions were examined. In addition to general clinical protocol of the study, the results of selective coronarography with determination of SYNTAX Score, MRI with contrast gadolinium strengthening and EchoCG with studying of tissue myocardial dopplerography and 2D-speckle tracking echocardiography were compared. Results. The signs of mechanical right ventricular myocardial dysfunction with preserved systolic function and standard right ventricular volumes by MRI data were detected. In particular, segmental deformation and deformation rate indices were changed. Manifestation of inhibited systolic dysfunction of the right ventricle depended on complexity and severity of coronary lesions: moderate invert correlation of SYNTAX Score and that of right ventricular ejection fraction by MRI data ( R s = -0,6) was observed. The higher is SYNTAX Score index, the more expressed is myocardial dysfunction (Tei index, R s = -0,4) and the lower is deformation at the level of tricuspid valve fibrous ring ( R s = -0,5). Conclusions. Tissue myocardial dopplerography and 2D-speckle tracking echocardiography included into the protocol of examining patients with multivascular coronary lesions for the purpose of assessment of the right ventricular function permits to confirm its involvement into the process of ischemic heart remodeling.

PECULIARITIES OF ENTERAL INSUFFICIENCY COURSE AGAINST THE BACKGROUND OF ACUTE ABDOMINAL PATHOLOGY
Abstract
Aim. To assess the peculiarities of enteral insufficiency syndrome at the example of patients with disseminated peritonitis. Materials and methods. The work was based on examination of 98 patients with purulent peritonitis. The severity of enteral insufficiency syndrome (EIS) taking into account peritonitis staging was estimated. Procalcitonin level as a marker of septic process was studied. Results. Among patients with reactive stage of peritonitis, only degrees I and II EIS were found. In patients with the toxic stage of disseminated peritonitis there predominated degree II EIS with the rate of 60,8 % (31 persons); degree III EIS was detected in 14 cases (27,4 %). At the terminal stage of peritonitis, degree III EIS was detected in 80 % of patients and degree II EIS - in 20 %. Blood procalcitonin level exceeded the norm that indicated bacterial nature of intoxication. Conclusions. There is a direct correlation between the enteral insufficiency syndrome and the peritonitis severity; procalcitonin level is closely associated with peritonitis severity and enteral insufficiency.

CEREBROVASCULAR DISTURBANCE PREDICTORS IN PATIENTS AFTER CORONARY ARTERY BYPASS GRAFT SURGERY
Abstract
Aim. To detect the perioperative insult predictors in patients with isolated coronary artery bypass grafting. Materials and methods. At Perm Federal Center of Cardiovascular Surgery, 2823 coronary artery bypass graft surgeries were performed over the period from January 2013 to December 2014. Results. The total hospital lethality among patients with isolated coronary artery bypass grafting was 1,2 % (36). Perioperative acute stroke (AS) was revealed in 32 (1,1 %) patients. To carry out the analysis, we divided patients into 2 groups: group A - 32 patients with AS diagnosed in the postoperative period, and group B - 2791 patients without severe cerebrovascular disorders. The analysis showed that in group A, there were significantly more female patients - 13 (40,6 %) versus 543 (19,5 %) in group B ( p < 0,01) as well as patients over 60: 21 (65,6 %) and 1251 (44,8 %), respectively ( p < 0,05); over 70: 9 (2,1 %) and 348 (12,5 %) patients, respectively ( p < 0,05). In group B, the number of patients with rhythm disturbance by atrial filbrillation type was 244 (8,7 %), in group A - 7 (21,9 %), that is reliably higher ( p < 0,01). In AS group, diabetes mellitus was found in 12 (37,5 %) patients, in group without AS - in 212 (7,6 %) ( p < 0,01). Significant differences were obtained by the quantity of patients with brachiocephalic artery atherosclerosis - 17 (53,1 %) in group A and 624 (22,4 %) in group B ( p < 0,01), patients with low extremity artery atherosclerosis - 16 (50,0 %) and 715 (25,6 %), respectively ( p < 0,01). Conclusions. The most significant predictors influencing the risk for occurring perioperative insult are concomitant brachiocephalic artery atherosclerosis, low extremity artery atherosclerosis, rhythm disturbance by atrial filbrillation type, diabetes mellitus, middle age.

CLINICOLABORATORY PECULIARITIES OF INFECTIOUS MONONUCLEOSIS IN PRESCHOOL CHILDREN
Abstract
Aim. To study the clinical and laboratory peculiarities of infectious mononucleosis (IM) in preschool children depending on etiological factor. Materials and methods. Clinicolaboratory peculiarities of IM depending on etiological factor were analyzed in 60 patients aged 1-6 years (20 patients with Epstein-Barr virus-associated IM (EBV-IM), 20 - cytomegalovirus (CMVI) IM and 20 - mixed etiology mononucleosis (EBV+CMVI). Results. It was established that EBV-IM- caused intoxication occurred reliably more often than CMVI-IM (EBV-IM 18 patients, CMVI-IM 8 patients, p = 0,02). In case of mixed IM, splenomegalia occurred more often than in IM caused by one etiological factor (mixed IM - 18 children, EBV-IM - 13, CMVI-IM - 13, p = 0,05). In case of EBV-IM and mixed IM, all changes in blood were more marked than in CMVI-IM. Conclusions. Against the background of therapy, fiver and intoxication were the first to disappear. The most long preserved symptom was stuffiness in nose. Lymphomonocytosis, transaminasemia, atypical blood mononuclear leukocytes were more often observed in EBV-IM and mixed etiology IM. During one year after discharge from the hospital, all children more often fell ill with respiratory diseases, especially in case of CMVI-IM.

ROLE OF RESPIRATORY TRACT INFECTION IN FORMATION OF INFANTILE ATOPIC PHENOTYPE
Abstract
Aim. To study the formation of atopic phenotype in children who had respiratory infection in the newborn period. Materials and methods. Retrospective study of 36 children who had respiratory infection in the neonatal period with subsequent examination at the age of 5-6 years was carried out on the basis of Perm Children’s City Clinical Hospital № 13. Results. Children with congenital pneumonia in 94,4 % of cases were found to suffer from atopic dermatitis, that is reliably more often than children with acute respiratory infection (50,0 %) in the neonatal period ( p < 0,01). All children with newborn respiratory infection form later the group of children who frequently fall ill. However, in the group of children with congenital pneumonia, complications of acute respiratory diseases occur more often, in particular, bronchoobstructive syndrome (44,4 % vs. 5,6 %, p < 0,05). No reliable differences between the groups were detected while studying respiratory resistance (hyperreactivity of bronchi was observed in 33,3 and 45,5 % of cases, respectively). In children who suffered from congenital pneumonia, IgE level is raised significantly more often ( p < 0,05). Conclusions. Children with congenital pneumonia, later on have high susceptibility to respiratory infections with development of complications that is an unfavorable factor for development of allergic diseases. Presence of atopic dermatitis, bronchial hyperreactivity and elevated sensitizing level contributes to formation of atopic phenotype as a risk factor for development of bronchial asthma.

PECULIARITIES OF COGNITIVE STATUS IN YOUNG WOMEN WITH MILD AND MODERATELY SEVERE IRON-DEFICIENCY ANEMIA
Abstract
Aim. To give the comparative characteristic of cognitive status in women depending on presence of iron-deficiency anemia, to study the possibilities of restoring the available cognitive deficiency against the background of anemia correction with iron preparations. Materials and methods. The study included 40 women aged 18 to 44 years, who were diagnosed mild and moderately severe iron-deficiency anemia. Complex clinicolaboratory and neuropsychical examination was carried out using MoCa test, Gotland, Spilberger-Hanin scales, asthenia estimation scale (MFI-20) before anemia therapy, 12 and 24 weeks after it. Comparison was fulfilled with the control group of nonanemic women. Results. When analyzing cognitive functions before anemic therapy in the group of mild and moderately severe iron-deficiency anemic patients aged 18 to 44 years, we detected mild cognitive disorders, predominantly attention, speech and memory functions. Anemia correction, normalization of hemoglobin, iron and blood serum ferritin against the background of anemia therapy with iron preparation were associated with reduced manifestation of cognitive disorders. Conclusions. The study results indicated that ferrotherapy reliably restores the available cognitive deficiency in young patients diagnosed mild and moderately severe iron-deficiency anemia. However, despite restoration of hematological indices, correction of cognitive deficiency and improvement of patients’ health status, asthenic component is preserved.

PECULIARITIES OF PNEUMOCOCCAL PNEUMONIA COURSE IN MEDICAL PERSONNEL
Abstract
Аim. To detect the clinical peculiarities of pneumococcal pneumonia course among medical personnel. Materials and methods. Over the period of 2001 to 2014, 49 patients diagnosed community-acquired pneumococcal pneumonia were examined on the basis of Perm Regional Clinical Infectious Hospital. Results. Analysis of the clinical course of S. pneumonia -induced community-acquired pneumococcal pneumonia in the group of medical personnel permitted to establish a number of peculiarities, which should be taken into account for diagnosis of these diseases. The disease was characterized by moderate and severe course with extensive pulmonary-tissue damage, clear complains and late response to bacterial inflammation in blood tests. Frequency of antibiotic-resistant S. pneumonia strains causing pulmonary-tissue damage was 16,3 % that exceeds the analogous index in the group of patients who do not belong to medical personnel. Conclusions. Peculiar features including difficulties in diagnosis of S. pneumonia -induced community-acquired pneumococcal pneumonia, severe course, significant number of cephalosporin and fluoroquinolone-resistant pneumococcal strains prove the need for specific prevention of medical personnel from pneumococcal infection.

TOBACCO SMOKING FREQUENCY AMONG PREGNANT WOMEN AND ITS ASSOCIATION WITH OBSTETRIC COMPLICATIONS
Abstract
Aim. To study the peculiar features of pregnancy course in smokers and to estimate the adequacy of preventive measures in high risk group for obstetric complications. Materials and methods. Health cards of 2270 pregnant women, who visited the Center of Family Planning and Prenatal Diagnosis of Perm State Medical University named after E. A. Wagner, were analyzed. Results. It was revealed that before pregnancy the share of smokers was 24,3 %. Among them, 78,5 % of women continued smoking during pregnancy, that is, prevalence of smoking among pregnant women is 190 per 1000. Hyperhomocysteinemia was detected in 69,5 % of smoking women. Conclusions. Every tenth pregnant woman is a smoker that permits to attribute her to the risk group for complicated pregnancy course from the early terms of pregnancy; smoking in most women is the cause of hyperhomocysteinemia and the risk factor for miscarriage and fetal growth retardation syndrome.

Abstract
Aim. To assess the dynamics of the quality of life in children with attention deficit and hyperactivity symptoms (ADHS) against the background of complex rehabilitation including hypoxihypercapnic training with respiratory simulator “Carbonic”. Materials and methods. Sixty three children (aged 10-15 years) diagnosed ADHS were divided into 2 randomized groups: the main group - 33 children receiving the basic rehabilitation complex with addition of hypoxihypercapnic training by means of respiratory training simulator “Carbonic”, the comparison group - 30 children receiving the basic rehabilitation complex alone. The quality of life was assessed by means of PedsQL 4.0 questionnaire before and after treatment. Results. Before treatment, the lowest quality of life was noted by the scales “Emotional State” and “Communication”. After treatment, there was statistically significant increase in the values by the scales “Emotional State” (by 43,1 % ( p < 0,05) in main group and by 20 % ( p < 0,05) in comparison group), “Communication” (by 67,2 % ( p < 0,05) in main group and by 31,8 % ( p < 0,05) in comparison group), “School” (by 17 % ( p < 0,05) in main group and by 12,9 % ( p < 0,05) in comparison group). Conclusions. After the course of rehabilitation including hypoxihypercapnic training with respiratory training simulator “Carbonic”, a reliable positive dynamics in the quality of life indices such as “Emotional State”, “Communication”, “School” was fixed. In the comparison group, there was also noted a reliable dynamics of these indices, but it is less significant than in the main group.

CARNITINE CHLORIDE EFFECT ON FUNCTIONAL STATE OF MITOCHONDRIA IN CONDITIONS OF NITRIC OXIDE SYNTHESIS DEFICIT
Abstract
Aim. To study the effect of carnitine chloride on functional state of mitochondria and endogenous carnitine content in conditions of L-NAME-induced decrease in nitric oxide synthesis (II). Materials and methods. Twenty four Wistar rats were divided into the following groups: the control group, the group with intraperitoneal introduction of L-NAME in the dose of 25 mg/kg for 7 days and the group receiving L-NAME by the analogous scheme against the background of introduction of carnitine chloride in the dose of 300 mg/kg for 21 days. The animals experienced the study of lactate dehydrogenase (LDG), succinate dehydrogenase (SDG), superoxide dismutase (SOD), lactate, nitric oxide (II), carnitine (total, free, bound) and nonetherified fatty acid concentrations in the rat cardiomyocyte mitochondria. Results. L-NAME in the dose of 25 mg/kg led to decrease in NO metabolite (by 21,5 %, p < 0,05) and lactate (by 56 %, p < 0,05) concentrations in myocardiocyte mitochondria; at the same time, it increased nonetherified fatty acid (by 290 %, p < 0,05) and total carnitine (by 162 %, p < 0,05) content as well as activity of all the three measured oxidoreductases in mitochondrial cardiac tissues as compared to the control animal indices (LDG by 160 %, p < 0,05; SDG by 109 %, p < 0,05; SOD by 133 %, p < 0,05). Preliminary introduction of carnitine chloride induced reliable significant growth of SDG (by 163 %, p < 0,05) and SOD (by 376 %, p < 0,05) activity, rise in NO metabolite (by 437 %, p < 0,05) and lactate (by 62 %, p < 0,05) concentrations, as well as to fall in fatty acid (37 %, p < 0,05) and total carnitine (by 35 %, p < 0,05) concentrations and LDG activity (by 50 %, p < 0,05). Conclusions. Preliminary administration of cortinine chloride in the dose of 300 mg/kg before introduction of L-NAME in the dose of 25 mg/kg normalizes carnitine homeostasis, prevents decrease in NO metabolite concentration, declines nonetherified fatty acid concentration and significantly elevates SOD and SDG activity in the rat cardiomyocyte mitochondria.

Abstract
Aim. To carry out morphological analysis of the changes in diameter of fetal and adult intraorgan microvessels of the lower third of esophagus. Materials and methods. Anatomical and histological methods were used to reveal the components of hemomicrocirculatory canal. The lower third of esophagus was studied in 18 human fetuses in the terms of 13, 23, 26, 32, 36 weeks of development, in 7 dead adults aged 41 to 50 years, who did not suffer from esophageal and hepatic diseases in the course of life. Results. Reliable age changes in external diameter of human esophageal arteries, veins, arterioles, capillaries, postcapillaries and venules using nonparametric statistical methods were detected. Conclusions. In dynamics of prenatal development, there occur unequal changes in capillary diameter: increase during the week 23 of gestation (up to 4,98 ± 0,11 mcm, p = 0,005), decrease beginning from the weeks 26 to 32 (4,07 ± 0,14 mcm, p = 0,000) and rise by the week 36 (5,40 ± 0,17 mcm, p = 0,000). Diameter of capillaries of the lower third of esophagus in adults is 9,43 ± 0,24 mcm ( p = 0,000).

EXPERIMENTAL NSAID-INDUCED HEPATOPATHY CAUSED BY LONG USE OF NIMESULIDE
Abstract
Aim. To assess the character of hepatic tissue lesion in experimental animals when modeling NSAID-hepatopathy with generally accepted histological methods. Materials and methods. Modeling of nonsteroid antiinflammatory drug-induced hepatic lesion in nonlinear white rats was performed with peroral introduction of nimesulide (Nise®) during 21 days in the following doses: 0,5 (therapeutic dose); 2,5 and 5 mg/kg. The control group was used for comparison. By the end of this experiment, histological material (hepatic tissue samples) was taken with euthanasia rules observed. Histological methods were used by standard protocols. Results. Peroral introduction of nimesulid during 21 days caused pathomorphological changes in hepatic tissue of experimental animals, typical for the toxic damage of the organ: sinusoid capillary dilatation, dystrophy and necrosis foci; at the same time, dose-dependent effect was revealed. Lymphocytic infiltrates were detected in hepatic tissue of animals perorally introduced nimesulide during 21 days; frequency of their detection increased with growth of the drug dose; the revealed changes require further study and explanation.

PULSE VISUALIZATION WITH VIDEOSIGNAL
Abstract
Materials and methods. The following principles of noisy signal filtration were used: linear smoothing forming the basic signal values, averaging by the period equal to mean pulse period, linear smoothing filtrating difference in videosignal and the obtained basic signal. The obtained difference is multiplied by the gain constant and added to the initial or the obtained basic signal. Conclusions. It was indicated that dynamic videoamplification, which does not apply filtration by the period equal to the mean value of pulse period, is of little use owing to artifacts available in the form of changes in brightness of lighting or relocation of the examined person. The offered algorithm differs from foreign analogs using dynamic amplification. The described mathematical methods for videosignal amplification are tested on videosignal of human forehead imaging.
