Annotation. The authors' study highlights the urgent problem of the development of toxic damage to the dentition under the influence of anticancer therapy in children and adolescents. The aim of the study was to study the violation of the homeostasis of the oral fluid and the severity of the carious process. Materials and methods. As part of a pilot study at the Russian Field Treatment and Rehabilitation Center, 63 children were studied the severity of mineral homeostasis disorders and damage to the dentoalveolar system. Results. In 67% of patients in the main group, there was an increased tendency to form carious cavities. 54.5% of them have complicated caries. One third of patients had more than five carious teeth. In the control group, carious lesions of the teeth in only three patients (20%), with the involvement of 1-3 teeth in the pathological process. Violation of enamel formation was diagnosed in 36% of children of the main group. There is a tendency for the accumulation of the studied microelements in the oral fluid, while in the blood serum there is a normal or insignificant decrease in their content. According to the literature, this may indicate destruction in the oral cavity. Deviations in the homeostasis of chemical elements in children who completed the treatment of malignant neoplasms and children in the control group were revealed. An increased content of osteotrophic microelements was found to correlate with the destructive processes of the teeth. Conclusion. It seems appropriate to study the severity of morphological changes in hard tissues of teeth and the electrolyte composition of mixed saliva in children and adolescents who have been cured of malignant neoplasms. The results of studies of gastric cancer, as an indicator of metabolic disorders, will make it possible not only to reveal the imbalance of macro- and microelements, but also to establish the effectiveness of adaptation mechanisms aimed at normalizing the elemental composition of the oral fluid.

Endothelial dysfunction is considered one of the main mechanisms for the further development of arterial hypertension (AH) and its complications, and endothelin-1 (ЕТ-1) plays one of the key roles in this process. Endothelium is drawn into the pathological process at the earliest stages of AH development. ЕТ-1 is currently considered as a marker and predictor of the stage and consequences of AH, chronic heart failure (CHF), coronary heart disease (CHD), in particularly, acute myocardial infarction (MI), heart rhythm disorders, pulmonary hypertension, atherosclerotic vascular injury, target vascular disorders. One factor that may influence the level of ЕТ-1 is the endothelin-1 gene Lys198Asn polymorphism, which is considered by many researchers as a possible genetic marker of AH. However, the effect of this polymorphism on the level of plasma ЕТ-1 level in patients with AH of varying severity in Ukraine is understudied. The basis of this work were the materials of a complete examination of 160 patients with a verified diagnosis of AH I, stage II of 1, 2, 3 degrees (main group) and 110 apparently healthy persons (control group). Patients of the main group were divided into three subgroups: 1st group ­– 75 patients with normal body weight; 2nd group – 48 overweight patients; 3rd group – 37 patients with alimentary obesity. In obese patients, the waist circumference in women was around 103 (96–115) cm, and in men – 108 (105–116) cm, which indicates an abdominal type of obesity in these patients. As a result of the study, it was found that the level of ЕТ-1 is higher in patients with AH who suffer with overweight and obesity as compared with patients with AH and normal body weight. Also, the peptide level depends on the genotype of patients and is higher in AH patients with the genotype Asn198Asn and Lys198Asn as compared to carriers of the genotype Lys198Lys.

Anti Inflammatory

The high prevalence of inflammatory processes in the periodontitis of children, the ineffective effectiveness of preventive and curative measures can contribute to the development of generalized periodontitis, therefore it remains urgent to develop pathogenetic effects in the treatment of chronic catarrhal gingivitis.The aim of the study – a comparative assessment of the traditional treatment of chronic catarrhal gingivitis in children aged 6–7 years with therapy using an anti-inflammatory gel with neovitin.Materials and Methods. 61 children aged 6–7 years, suffering from chronic catarrhal gingivitis, were taken under clinical supervision and divided into groups: the main (30 children) and the comparative (31 children). All children underwent conventional therapy in accordance with the protocols for the provision of medical care – basic therapy. In the main group, for a month, pathogenetic agents were used: an anti-inflammatory gel with neovitin, hygiene products were recommended. In the comparative group, 3 % hydrogen peroxide solution was used for local therapy, for rinsing of the mouth (during the first week of treatment) – Rotokan, a therapeutic and prophylactic toothpaste.Examination and control examinations were carried out with the hygienic state of the mouth determined by the hygienic index of Yu. A. Fedorov and V. V. Volodkina, prevalence and intensity of the inflammatory process in the gums with the help of the Schiller-Pisarev test and the PMA index, oral fluid index (lysozyme content, formation of oxydradicals, urease activity, degree of dysbiosis, pH and viscosity).Results and Discussion. After the treatment, elimination of gum inflammation in patients of the main group was accompanied by a decrease in the PMA index by 3.8 times; formation of oxyradicals decreased in children of the main group by 6.35 %; in the comparative group – by 6.15 %. Urease activity decreased in children of the main group by 16.37 % (p<0.05), the viscosity of the oral fluid of children decreased in 2.65 times in the main group and in 2.13 times in the comparative group (p<0.05). The lysozyme content increased in children of the main group by 15.61 % (p<0.05) in the comparison group – by 9.63% (p<0.05). The treatment after 0.5 years caused an increase in the lysozyme content in the oral fluid of the children of the main group to the level of the control group. The degree of dysbiosis decreased in the main group, in the comparison group tended to increase.Conclusions. The use of the proposed therapy with gel with neovitin contributed to the best results of treatment: reducing the degree of inflammation of the gums, the number of visits to the doctor, improving the indices of nonspecific protection in the oral fluid of 6-7 years-old children and, to a greater extent, six months after the treatment.

In the case of radicular syndrome in patients with dorsopathy, degenerative dystrophic changes, which contribute to the creation of additional mechanisms of pain impulse and chronization of the pathological process, are diagnosed in the deep muscles. The study included 40 patients with dorsopathy of the lumbosacral spine and radicular syndrome, with the average age of 45,3±1,5years, who were divided into 2 groups comparable in age and clinical and functional characteristics: the main group of 20 patients who were treated with laser phoresis of biologically active substances and the control group of 20 patients who received standard pharmacotherapy. As a result of the study, a significantly more pronounced improvement in the state of microcirculation in the paravertebral muscles when using phytoextracts laser phoresis was proved, which was confirmed by radiothermometry and transcutaneous oximetry. The analysis of radiothermometry and oximetry parameters obtained 3 months after the end of the course showed the stability of the therapeutic effect in 96% of patients in the main group, while in the control group, 50% of patients showed a regression of the effect obtained as a result of treatment. In longer terms, the therapeutic effect in 90% of patients of the main group was maintained for 9–12 months of follow-up, while in the control group — no more than 3–4 months.

The paper presents research results of patho-morphological effects of extremely low frequency rotating magnetic fields and pulsed traveling magnetic fields on the kidneys of mammals from the perspective of in-formation theory. The study was conducted in four experimental groups and one control group, each of which consisted of 15 adult mice line S/Bl6. The following information characteristics were determined for all groups: information capacity, i.e. the maximum structural diversity of functional systems, information entropy, information organization, information relative entropy and the coefficient of relative organization of the system. Analysis of the values of information characteristics have allowed to establish that the lowest values of information entropy and maximum values of the coefficient of relative organization of the system were obtained in the groups with the most severe pathological changes. This indicates the formation of stable equilibrium as the norm, and in terms of irreversible pathological process. The results of the correlation analysis in all groups showed that the highest accuracy of prediction have regression model for relative information entropy, obtained in the control group and in group 2, in which severe pathological changes didn’t observed.

Abstract Background: The relationship between breech presentation and trochlear dysplasia had been confirmed. However, the pathological process of breech-related trochlear dysplasia remain unclear. This study aimed to establish an animal model to simulate breech presentation and to analyze the pathological process of the femoral trochlea.Materials and Methods: One hundred and twenty neonatal rats were randomly assigned into a control group and two experimental groups that were swaddled (using surgical tape) to keep the hip flexed and knees extended to simulate human breech presentation for the 5 days (short Swaddling) and the 10 days (prolonged Swaddling) of life. Gross and cross-sectional observation, histological staining measurement in two experimental time points (5, 10 days after birth) were conducted to evaluate the morphological changes of the femoral trochlea.Results: The incidence of trochlear dysplasia increased with the Swaddling time. Rats in the prolonged Swaddling group had the high prevalence of trochlea dysplasia (52 of 60), followed by short Swaddling group (42 of 60). Gross and cross-sectional observation showed a shallower trochlea groove in two experimental groups. Histologicalstaining measurement indicated that the trochlear sulcus angle and trochlear sulcus depth were significantly different between the experimental group and the control group since day 5 and day 10. Conclusion: In this model, breech presentation had a adverse influence on neonatal knees and could induce trochlear dysplasia. What is more, this study also showed that the more time in breech presentation, the more incidence of trochlear dysplasia.

The results of a comprehensive analysis of clinical, anthropometric data and an assessment of the psycho-emotional status of 62 children and adolescents (mean age 11.8 ± 3.0 years) with atopic dermatitis and overweight or varying degrees of obesity (the main group) are presented. The control group included 60 patients (mean age 10.1 ± 3.6 years) with atopic dermatitis and body weight corresponding to age and gender standards. In the main group, 45.2% were children and adolescents with overweight, and with first-, second- and third-degree obesity were 25.8, 11.3 and 17.7% respectively. The severe course of dermatosis in the main group was recorded 1.4 times more often than in the control group. With the aid of univariate analysis of the treatment efficacy predictors, it was revealed that weight loss and improvement in psycho-emotional state can significantly increase the treatment efficacy of atopic dermatitis in children and adolescents with overweight and obesity, which indicates the advisability of interaction between a dermatologist, endocrinologist and psychotherapist in the treatment of this category of patients.

We studied the autopsy material obtained from 7 children who died in the neonatal period in order to evaluate the composition of lymphocytes of the intestinal mucosa against the background of morphological changes in the tissues of the gastrointestinal tract in newborns with sepsis. The main group consisted of 4 children with neonatal sepsis, the control group – of 3 newborns who died from other causes. The research material included the specimen of the small and large intestine.Results. Small intestine: it was found that there were less CD4 + lymphocytes in the small intestinal mucosa in the group of children who died from neonatal sepsis in 75% of cases than in the control group, but this difference was not statistically significant (p=0.1). There were no differences in the number of CD8 + and CD20 + cells in the studied groups. Large intestine: the number of CD4 + lymphocytes of the mucous membrane of the colon was greater in the main group of children than in the control group (p=0.03). An increase in the number of CD4 + cells was registered in 3 of 4 cases of neonatal sepsis. The number of CD8+ and CD20+ lymphocytes in the studied groups was the same (р>0.05).Conclusion. The increase in T-lymphocytes CD4+ in the mucous membrane of the large intestine is probably connected with the antigenic stimulation of opportunistic intestinal bacteria. We found no morphological signs of the suppression of the cells of adaptive immunity associated with the intestinal mucosa.

Relevance: inflammatory processes in the oral mucosa are often found in diseases of the gastrointestinal tract, which is explained by the common functions and unity of all parts of the digestive system.Purpose – to study the effect of the studied drugs on the state of antioxidant-prooxidant systems of the oral mucosa in patients with chronic pancreatitis.Materials and methods: we examined 118 patients, of whom 62 were men (mean age 39.6 ± 16.4 years) and 56 women (mean age 40.3 ± 15.7 years); of these, 34 patients (control group) are practically healthy people without somatic pathology and 84 patients with chronic pancreatitis who were divided into two groups. The first (main) group - 46 people who, in addition to the drug therapy prescribed by the gastroenterologist, were prescribed the drug “Multiflora” 1 tablet 1 time per day with meals for 30 days. Also, the patients of the main group, after each meal, rinsed their mouths with “Enoant” food concentrate at a dilution of 1: 5 and applied it inside with 1 tablespoon 2 times a day, diluted with water in a ratio of 1: 5. The second (comparison group) - 38 people who, in addition to treatment of chronic pancreatitis, were treated with the oral mucosa according to the generally accepted method - prescribed fluconazole 150 mg 1 time a day, rinsing with 2% borax solution in glycerol after eating for 14 days. Unstimulated oral fluid of the examined patients served as the material for the study. In all groups, the activity of the catalase enzyme was determined by the method of S.V. Girina (1999), the level of malonic dialdehyde (MDA activity by reaction with thiobarbiturate acid to form a trimethine complex) and antioxidant-prooxidant index of unstimulated oral fluid by the method of А.P. Levitsky (2010). Laboratory research was carried out at the time of the initial examination before the start and on the 30th day of treatment.Results: in the comparison group after treatment, an increased concentration of malondialdehyde in the oral fluid, as well as reduced indicators of the API index and catalase activity confirm the presence of inflammatory processes in the oral mucosa. The application of the proposed therapeutic complex to patients of the main group significantly reduces the concentration of malondialdehyde in the oral fluid, proving its anti-inflammatory effect on the oral mucosa. An increase in the antioxidant-prooxidant index and an increase in catalase activity indicates an increase in the body’s defenses in patients of the main group.Conclusion: the use of the proposed therapeutic complex in patients with inflammatory diseases of the oral mucosa suffering from chronic pancreatitis contributes to the elimination of inflammatory and degenerative processes and the restoration of the normal level of protective systems in the oral mucosa.

Background. Gynecological malignant neoplasms (GMN) are the leading disease group among female cancers.Objective: to characterize GMN in females occupationally exposed to ionizing radiation over prolonged periods.Materials and methods. The cohort considered in the study included females (n = 5689) who had been hired at the Mayak Production Association in the period between 1948 and 1982. All these females were exposed to ionizing radiation over prolonged periods during their employment. They were followed up until 31.12.2018. Two groups of females were identified in the study cohort: the one with a verified GMN (the main group) and another one free of GMN (the control group). The occupational and reproductive characteristics were analyzed for the identified groups of females, and associations of GMN with various risk factors were assessed.Results. Among GMN the uterine corpus cancer had the top position. In 70 % of the females GMN were diagnosed during a menopausal period. The females of the main group demonstrated significantly higher frequency of underlying pre-malignant conditions (endometriosis, uterine myoma, endometrial hyperplastic processes, ovarian epidermoids, menopausal bleedings) compared to the control group.Conclusion. Studies of GMN in females occupationally exposed to ionizing radiation over prolonged periods for sure are of a certain scientific and practical interest. The findings can provide the basis for specialized cancer care for employees of the nuclear industry.

Introduction: It has been proven that the oral hygiene is determined by the quantitative and qualitative composition of the bacterial biofilm, by the local immunity, and the rheological properties of the oral fluid. The aim of this study was to observe the dynamics of these parameters in the short term postoperative period after dental implantation in patients with a different state of periodontal tissues, depending on maintenance therapy. Materials and methods: 124 healthy people, aged 18 to 34, were examined. Depending on the follow-up maintenance therapy after dental implantation, patients were divided into two equal study groups: patients of the main group received the proposed differentiated maintenance therapy, the volume and multiplicity of which were determined by the initial oral hygiene state; patients of the control group underwent traditional treatment. Patients with healthy periodontium comprised a comparison group. Using the digital drop shape, the viscosity coefficient b2 was determined. Identification of the biofilm’s microorganisms was carried out with aerobic and anaerobic cultivation techniques. The presence of immunoglobulin SIgA in the oral liquid was determined by Manchini’s radial immunodiffusion method. Results: In the main group, the viscosity coefficient b2 and the content of SIgA immunoglobulin in the oral fluid were significantly higher than in the control group (p <0.05). The proposed maintenance therapy led to the restoration of the species domination of the probiotic microflora, proportional to the healthy periodontium both in the frequency of selection, and the level of insemination. The indicated dynamics of these parameters leads to a probable decrease of the Green-Vermillion HI (p<0,05). Conclusions: Proposed maintenance therapy leads to a probable improvement of the oral hygiene state based on Green-Vermillion HI, caused by the normalization of the surfactant properties of the oral liquid, biofilm’s ratio of microbial associations, and local oral hygiene.
