Abstract. The relevance of the topic is related to the need to improve methods of preparation of dentitions for orthopedic treatment, taking into account the defects of dentitions in patients with reduced occlusion height, taking into account the condition of the masticatory muscles and temporary use of plastic dentures, which provide gradual lifting of occlusion to normalize the masticatory group muscles and reorganization of myostatic reflexes. The aim of the research. Improving the effectiveness of preparation for orthopedic treatment of patients with partial tooth loss, with reduced occlusion height, by improving the design of a temporary bridge-based prosthesis. Materials and methods of research. We examined, treated and conducted clinical observation of 93 patients, who were divided into three groups according to the height of the reduction in occlusion, to achieve this goal and solve problems during the dissertation. Group 1 consisted of 32 patients with included dentition defects with reduced occlusion height up to 2 mm (n=32), group 2 - patients with included dentition defects with reduced occlusion height up to 2-4 mm (n=31), group 3 - these are patients with included dentition defects with reduced occlusion height up to 4-6 mm (n=30). All patients of the main groups belonged to the second and third age groups according to the WHO, aged 35-55 years. The control group (n=30) are young people who belonged to the 1st age group according to the WHO with intact dentition, without concomitant somatic and dental pathology, were admitted in one visit. Also, 123 fiberglass-reinforced plastic prostheses were made. Research results. When drawing up a plan for orthopedic treatment of patients with reduced occlusion height, we took into account possible complications, which are characterized by chipping of the facing material, pathological changes in the temporomandibular joint and masticatory muscle group. We have improved the method of manufacturing non-removable temporary plastic orthopedic constructions by reinforcing with fiberglass tapes and beams, to prevent them and gradually raise the bite. Expanded data on the dynamics of changes in myostatic reflexes and the effectiveness of the use of fixed orthopedic constructions, depending on the pathological process, the timing of adaptation of the masticatory muscle group to orthopedic constructions, according to the degree of reduction in occlusion height. The absence of complaints of breakage and other technical defects of the proposed temporary orthopedic constructions in 100% of cases, successfully allows to use it in the clinic of orthopedic dentistry. A new method of preparing patients for permanent orthopedic treatment by combined reinforcement of temporary non-removable bridge constructions with fiberglass tapes and beams is proposed, which differ in that after preliminary modeling of the frame of the bridge constructions, the technology of double reinforcement, model two support platforms with a step-like transition between them, in which fiberglass tapes and beams are fitted with dental tweezers, after which they are polymerized by the generally accepted method with a photopolymer lamp. Complete the modeling of the constructions and polymerize the prosthesis in the pneumopolymerizer with subsequent grinding and polymerize the prosthesis. Conclusion. The results of the research revealed the high efficiency of the improved method of manufacturing non-removable makeshift plastic of orthopedic constructions.

Aesthetic and hygienic requirements of patients with reduced bite height necessitate the use of modern orthopedic constructions. The main cause of this disease is pathological abrasion of the hard tissues of the teeth, the prevalence of which ranges from 4 to 57% at a young age, reaches 91% in the elderly and is accompanied by both morphological and functional disorders of the dental-maxillary system. The aim of the research. Research the features of the diagnosis of dental status in patients with reduced bite height and timing of their treatment. Materials and methods of research. Determine the degree of reduction in the height of the bite in persons with pathological abrasion of the hard tissues of the teeth of varying severity compared with the norm and features of its recovery. Research results and their discussion. In order to prepare for orthopedic treatment, we determined the height of the bite in 123 patients. Accordingly, they were divided into three groups. Group 1 consisted of 32 patients with included dentition defects with reduced bite height up to 2 mm (n = 32), group 2 - examined with included dentition defects with reduced bite height 2-4 mm (n = 31), group 3 are patients with included dentition defects with reduced bite height of 4-6 mm (n = 30). All persons of the main groups belonged to the second and third age groups according to the WHO, aged 35-55 years, who required orthopedic treatment with fixed constructions of dentures. The control group (n = 30) are young people who belonged to the 1st WHO age group (age - 18-34 years) with intact dentition, without concomitant somatic and dental pathology, were examined in one visit. In order to study the degree of dependence of bite height reduction between incisors, canines, premolars and molars, we studied 30 gypsum models of supergypsum of the upper and lower jaws without reduction of bite height and 93 - with varying degrees of pathological abrasion of tooth hard tissues of all examined people. The models were fixed in a standard articulator in the central occlusion position. Using a caliper, we determined the size of the tooth crowns and compared it with standard sizes. In this research, we found the dependence of the degree of reduction in the height of the bite in the area of molars - premolars - incisors and canines in the ratio 1: 1,25: 1,5. We performed orthopedic treatment and subsequent clinical observation for each patient for 6 months, examining their condition after fixation of prostheses in 1 week and in 1, 3 and 6 months after orthopedic treatment. Based on the diagnosis of bite height reduction, we provided practical recommendations on the terms of use of fixed pharmacy bridges prostheses according to the degree of bite height reduction in the examined people. In the case of patients with a decrease in bite height by 3-4 mm, permanent orthopedic treatment is possible in 90 days after fixation of temporary orthopedic constructions in the oral cavity, and in patients with a reduced bite height of more than 4 mm - in 180 days. Conclusions. According to the results of the research, a high efficiency of determining the degree of reduction in bite height in preparing patients for permanent orthopedic treatment depending on the severity of the pathological process.

Purpose: Radiographic abnormalities in the pubic bone and symphysis are often seen in athletes with groin pain. The aim was to create a grading scale of such radiologic changes. Material and Methods: Plain radiography of the pelvic ring including the pubic bone and the symphysis was performed in 20 male athletes, age 19–35, with long-standing uni- or bilateral groin pain. We used two control groups: Control group 1: 20 healthy age-matched men who had undergone radiologic examination of the pelvis due to trauma. Control group 2: 120 adults (66 men and 54 women) in 9 age groups between 15 and 90 years of age. These examinations were also evaluated for interobserver variance. Results and Conclusion: The grading scale was based on the type and the amount of the different changes, which were classified as follows: No bone changes (grade 0), slight bone changes (grade 1), intermediate changes (grade 2), and advanced changes (grade 3). The grading scale is easy to interpret and an otherwise troublesome communication between the radiologist and the physician was avoided. There was a high interobserver agreement with a high kappa value (0.8707). Male athletes with long-standing groin pain had abnormal bone changes in the symphysis significantly more frequently and more severely ( p>0.001) than their age-matched references. In asymptomatic individuals such abnormalities increased in frequency with age both in men and women.

We aimed to reveal psychological symptoms of young university students (18-25 y/o) with no secondary disease with complaints of migraine headaches. We compared the psychological symptoms with a young control group that did not present headaches and other studies examining migraines in different age groups to determine any similarities. The study consisted of 75 migraine cases; 13 with aura and 62 without aura) and 42 non-headache control subjects. The International Classification of Headache Disorders 3 (ICHD-3) with criteria questions and the Psychological Symptom Research Scale were applied to all participants and SPSS Statistics Program evaluated the data. Findings: 1) In the test of Descriptive Statistics for the Sample of Students, average values of both sexes were taken and found the average values of the migraine groups were higher than control group. 2) The Anova Test found differences in the diagnostic group besides depression (Somatisation p<., others p<.01) with no significant difference in depression (p=0.315). 3)The Pearson Correlation Analysis, found no association between age and psychological symptoms. There’s a significant relationship between psychological symptoms with somatisation (besides paranoid) (p<.05). There’s a significant relationship between depression and other psychological symptoms (p<.05). There’s a significant relationship between anxiety, obsession, interpersonal relationships, psychoticism, paranoia, anger, phobia, additional scale and other psychological symptoms (p<.01). Result: The study demonstrated psychological symptoms in young migraineurs. The average psychological symptoms of both migraine groups were higher than the control group, this showed psychological symptom similarities between young migraineurs and migraine patients of different age groups.

Background. Gout is still one of the major health problems despite significant advances in treatment in recent years. It has been proved that pathogenetic mechanisms of development and progression of gout are associated with nonalcoholic fatty liver disease. Complex pathogenic treatment of patients aimed at different parts of the pathological process has recently been supplemented with the enterosorbents. Objective. The aim of the research is to study the clinical features of gout with concomitant nonalcoholic fatty liver disease (NAFLD) and to evaluate the effect of carbon enterosorbent on its course. Methods. 123 patients were involved in the study. They were divided into 2 groups: group 1 included patients with gout without liver damage, and group 2 included patients with concomitant NAFLD. Each of these groups was divided into subgroups, in which the patients received carbon enterosorbent carboline plus basic treatment. The control group consisted of 30 healthy persons. Anamnesis, physical examination, uric acid (UA), C-reactive protein (CRP) content, erythrocyte sedimentation rate (ESR) in serum were determined. Gout activity was evaluated using the Gout Activity Score (GAS). Results. Basic treatment in combination with carbon enterosorbent contributed to faster cure of intoxication, pain and joint syndromes, as well as decrease of the inflammatory process activity. Conclusions. The course of gout in the patients with concomitant NAFLD is more severe. Adding of carbon granular enterosorbent carboline in the complex treatment of patients with gout with or without concomitant NAFLD in the exacerbation phase contributes to a faster cureing dynamics of clinical and laboratory manifestations of the disease.

The aim: Is to evaluate the effectiveness of the proposed method of constructing occlusal surfaces of orthopedic structures by monitoring the dynamics of functional indicators of occlusion and the functional condition of the masticatory muscles. Materials and methods: The object of the study was made up by 64 patients with included defects of the dentition of the 3rd class according to Kennedy. Patients were divided into two equal groups – the main group (patients were treated by using the suggested method of construction of occlusal surfaces of orthopedic structures) and control (dentition defects were replaced according to the traditional protocol). Results: The results of evaluating the effectiveness of the proposed method showed that the index of symmetry of the anterior bundles of the temporal muscles dropped by 18.5%, the index of symmetry of the masticatory muscles reduced by 22%, the torque of the mandible reduced by 32%, the index of stabilizing occlusal – by 27%, relative efforts of balance disturbance for more than 10 % regarding the left and right reduced by a factor of 4.4, the rate of opening time was 1.5 times higher than before, the rate of time of opening of the jaws – 1.8 times. Conclusions: The use of the suggested method of orthopedic treatment with temporary structures leads to probable changes in the studied functional parameters in comparison with the control group (p <0,05).

Objective: We aimed to describe the presentations and biochemical characteristics of sepsis-like syndrome (SLS) in infants aged &lt;2 months who tested positive for SARS-CoV-2-in comparison to those in the same age group who were SARS-CoV-2-negative.Background: COVID-19 presents with a spectrum of manifestations, and children seem to have a favorable clinical course compared to other age groups. Limited data are available for symptomatic infants.Design: This was a case-controlled single-institution retrospective study on infants aged &lt;2 months admitted with SLS between 1 April 2020 and 1 July 2020. These infants were divided into 2 groups: Group 1 (n = 41), infants with positive nasal/oropharyngeal swab polymerase chain reaction (PCR) results for SARS-CoV-2; and Group 2 (n = 40), infants with negative PCR results for SARS-CoV-2 (control group). Details between both groups were reviewed and analyzed.Outcome: The clinical and laboratory data for SARS-CoV-2 -positive infants who presented with SLS may differ from those for infants with SLS who tested negative for SARS-CoV-2.Results: Overall, 105 infants were admitted with clinical sepsis: 41 were SARS-CoV-2-positive, and 64 were negative. Fever was present in 90% of SARS-CoV-2-positive infants vs. 80% of the negative group. SARS-CoV-2-positive infants had a higher incidence of nasal congestion and cough (39 and 29%, respectively) compared to the SARS-CoV-2-negative group (20 and 3%, respectively) (P &lt; 0.05). Poor feeding and hypoactivity occurred more frequently in the SARS-CoV-2-negative group (58 and 45%, respectively) than in the SARS-CoV-2-positive group (22 and 12%, respectively, P &lt; 0.004). Sepsis workup, including lumbar puncture, was performed in 67% and partial septic workup was performed in 23% of the SARS-CoV-2-positive infants. Full sepsis workup was performed in 92% of the SARS-CoV-2-negative group. Cerebrospinal fluid (CSF) cultures were negative in 26/27SARS-CoV-2-positive infants (an infant had Klebsiella meningitis). All the SARS-CoV-2-negative infants had negative CSF cultures. Blood culture was negative in both groups. Urine culture showed bacterial growth in 9 infants with SARS-CoV-2-negative sepsis.Conclusions: Our study showed that respiratory symptoms (cough and nasal congestion) were more prominent in the SARS-CoV-2-positive group, while poor feeding and hypoactivity were reported more frequently in the negative group. However, the clinical differentiation between COVID-19 disease and sepsis in such age groups is difficult. Therefore, screening young infants with SLS for SARS-CoV-2- is necessary during this pandemic.

ObjectiveTo compare the psychological adjustment and behaviour of congenital hypothyroidism (CH) children and their parents with a control group.Study designA cross-sectional study was carried out with 84 CH subjects diagnosed by neonatal screening (range 2.7–18.6 years), subdivided into four age groups: group 1 (2–5 years); group 2 (6–10 years); group 3 (11–13 years); and group 4 (14–18 years) and was compared with an age-matched control group. Patients were assessed using two questionnaires: Child Behaviour Checklist for parents and Youth Self-Report for children over 11 years of age.ResultsIn groups 1, 3 and 4, total score (TS), internalising score (IS=problems within the self) and externalising score (ES=conflicts with other people) as reported by parents were not significantly different in CH patients and in controls. In group 2, parents of CH children showed values of TS (P<0.05), IS (P<0.05), ES (P<0.05) and scores on other scales significantly higher than controls. In self-reports of groups 3 and 4, the behavioural scales were not significantly different in CH patients and in controls.ConclusionsPaediatricians should be informed about the increased risk of the development of behavioural problems at primary school age in CH patients. At this age special attention should be paid to parental worries and anxiety. However, it can be reassuring for the patients and parents to know that the problems may be related to CH, and that they may spontaneously disappear.

The aim of the study is to investigate the effectiveness of conservative therapy with the inclusion of cryoprecipitate in its composition and its effect on the angiogenesis of renal blood vessels in patients with purulent pyelonephritis. Materials and methods. The study included 30 patients aged from 20 to 45 years (6 men, 24 women) with acute purulent pyelonephritis. All patients were assessed for markers of angiogenesis in blood plasma: vascular endothelial growth factor (VEGF-A), angiopoietin 1 (Ang1) and angiopoietin 2 (Ang2). The patients were divided into two groups. Patients of group 1 (n = 15) received conservative therapy with the inclusion of cryoprecipitate, patients of group 2 (n = 15) received surgical treatment. The control group consisted of 10 healthy donors aged 2035 years, whose blood angiogenesis markers were determined to obtain reference values. Results. In the course of preliminary studies, the blood content of angiogenesis markers was determined in 10 healthy donors. The level of VEGF-A in patients of both groups and the level of Ang1 in patients of group 1 at admission to the hospital significantly exceeded the corresponding values in the control group. In group 2 patients, the level of VEGF-A and Ang1 remained elevated during treatment, which indirectly indicated an ongoing inflammatory process. The level of Ang2 in patients of both groups did not change significantly. Conservative treatment of group 1 patients showed high efficiency, which was confirmed by positive dynamics of clinical and laboratory indicators, as well as data from instrumental examination. Conclusions. The results obtained indicate the effectiveness of conservative therapy with the administration of cryoprecipitate in patients with purulent pyelonephritis, and the effectiveness of such treatment is comparable to the effectiveness of surgical treatment . The use of cryoprecipitate has an endothelioprotective and anti-inflammatory effect on blood vessels, stabilizes the processes of angiogenesis, which contributes to limiting the inflammatory process and its regression.

Objectives. Study of ways to increase the efficiency of immediate prosthetic treatment of patients with asymmetric distally unlimited defects of dental rows by using clinical relining of partial removable dentures with Ufi Gel P material from VOCO (Germany) to reduce the time of adaptation to dentures and normalize the functional activity of the masticatory muscles. Materials and methods. The efficiency of clinical relining of partial removable dentures using an elastic lining with Ufi Gel P from VOCO (Germany) was evaluated by electromyographic examination with BioEMG III electromyograph from BioRESEARCH Associates, Inc. (USA). The bioelectrical activity of the temporal and masseter muscles was evaluated during maximum voluntary clenching and mastication. The quantitative indicators of the amplitude of biopotentials (μV) and the qualitative characteristics of the chewing cycles were evaluated. Results. Our study has revealed that patients with asymmetric distally unlimited defects of dental rows had shown a significant decrease in the amplitude of biopotentials of the masticatory muscles compared to patients in the control group during maximum voluntary clenching and chewing, as well as a significant asymmetry of the bioelectric activity of the masticatory muscles on the right and left. During mastication there were significant differences in the size and duration of chewing cycles, a decrease in the duration of rest periods and the average number of chewing movements increased almost two times compared with intact dentition. A month after prosthetics, the indicators of bioelectrical activity of the masticatory muscles improved in both study groups of patients, but the most significant increase in amplitude was observed in the second group with a soft lining. There was also revealed a significant increase in the symmetry of bioelectric activity of the masticatory muscles, an improvement in the characteristics of the masticatory cycles and normalization of the activity and rest periods duration ratio in patients of the second group, while in patients of the 1st clinical group the indicators of symmetry did not change significantly. The average number of chewing movements required to chew the hazelnut kernel decreased to 38.7±16.2 and 29.3±10.7 respectively, in groups 1 and 2, which indicates an increase of masticatory efficiency. Conclusions. In the framework of this study, the high efficiency of Ufi Gel P (VOCO) elastic lining for the successful rehabilitation of patients with asymmetric distally unlimited defects in case of early prosthodontic interventions was proved. Our observations have shown that the use of the Ufi Gel P (VOCO) soft lining significantly increases the functional parameters of the masticatory system, shortens the period of adaptation to removable dentures and supports the formation of the alveolar processes relief without irregularities.

Abstract The issues of development and implementation of resource-saving technologies in broiler poultry farming have a complex purposefulness and their solution must be scientifically substantiated and cost-effective. The productive qualities of meat chickens and broiler chickens of the productive crosses are significantly influenced by many factors that make up the conditions of keeping and feeding. The use of Apex and Emicidin preparations both separately and in combination with each other when rearing chickens of the broiler parent flock of the Ross 308 cross had a positive effect on their productivity and the quality of hatching eggs obtained at the end of the productive period, at the age of 52 weeks. Egg production per initial hen exceeded that in the control group by 2.6% in experimental group 1 (Emicidin), by 3.2% in experimental group 2 (Apex 3010), and by 5.8% in experimental group 3 (combined use of Emicidin and Apex 3010). The determined zootechnical indicators showed high efficiency of the use of the GerbaStor preparation for the floor rearing of broiler chickens of the Ross-308 cross in conditions of increased stocking density in winter. The difference in the productivity index was 18 units, and in meat yield from 1 m² of floor, it was 1.37 kg (3.8%) in favor of the broilers of the experimental group 2, who received GerbaStor. The profitability of the production and sale of meat of broilers grown under an increased stocking density using the GerbaStor preparation was 3.95% higher than that of broilers in the control group.
