INFLUENCE OF SEROLOGICAL MARKERS OF BLOOD GROUPS UPON THE DEVELOPMENT OF VISUAL MEMORY IN HIGH SCHOOLERS AND STUDENTS.

OBJECTIVE: The aim: To investigate the influence of serological markers of blood groups of the AB0 system upon the development of short-term visual memory in high schoolers and students. PATIENTS AND METHODS: Materials and methods: The research involved 13-16-year-old high schoolers (boys) (n = 139) who were involved in various sports: group A - speed and strength sports (n = 74); group B - endurance sports (n = 65). The control group consisted of 13-16-year-old high schoolers (n = 106) and 17-20-year-old students (n = 212) who were not engaged in sports. The study of short-term visual memory was conducted using the "Memory for geometric shapes" method. RESULTS: Results: It was found that high schoolers and students with the 0(I) blood group have the best associative coupling with the properties of short-term visual memory. CONCLUSION: Conclusions: The use of serological markers of blood groups according to the AB0 system is possible in the genetic prediction of the development of visual memory in high schoolers and students. Herewith, the associative coupling is more pronounced in juvenility than in adolescence.

DIFFERENTIAL-DIAGNOSTIC INFORMATIVENESS OF THE MORPHOLOGICAL AND IMMUNOHISTOCHEMICAL STUDY OF PAROTID SALIVARY GLAND CYSTS.

OBJECTIVE: The aim: To conduct a general analysis of the results of the study of the morphological and immunohistochemical structure of cysts of the parotid salivary glands. PATIENTS AND METHODS: Materials and methods: Our study is based on the application of generally accepted, additional and special methods of examination, which concerns 21 patients who underwent surgical intervention to remove cystic formations of the parotid salivary gland. RESULTS: Results: It was established that there are 2-3 HLA-DR+ cells per 100 epithelial cells located in the basal and subbasal layers in the form of their continuous ribbon and their moderate infiltration of tissues within the acinar epithelium. In the epithelium, CD3+ cells were also detected in the number of 1 to 7 per 100 epitheliocytes and they were the most numerous, along with HLA-DR+ cells. Instead, the presence of CD4+ and CD20+ cells was not detected in the epithelium, unlike the subepithelial layer, where they occupied significant areas. In turn, the infiltration of CD8+ cells of the epithelial layer was established in the amount from 1 to 7 per 100 epitheliocytes. A moderate number of them was also determined subepithelially, and they were single directly in the cyst wall. CONCLUSION: Conclusions: Immunohistochemical study of the structural components of cystic formations is this is the direct way to establish the nature of the redistribution of immune cells in it, which is very important when conducting differential diagnosis in difficult and doubtful cases.

PERIODONTAL RESPONSE TO CYTOSTATIC DRUGS IN CHILDREN.

OBJECTIVE: The aim: To study the effect of different types of cytostatic drugs on the periodontium in children with malignant tumors. PATIENTS AND METHODS: Material and methods: The material for generalization was based at the results of examination of 44 patients with malignant tumors of the abdominal cavity who underwent preoperative treatment in the oncohematology department of Poltava Children's City Clinical Hospital. RESULTS: Results: In the absence of proper dental care in patients of this group, under the influence of chemotherapeutic drugs, significantly worsens the level of oral hygiene and the condition of periodontal tissues. There are also changes in the process of differentiation of the epithelial structures of the gingival margin, which is accompanied by an increase in smears - reprints of the number of inflammatory cells of the peripheral blood, both with preserved structure and destructive forms. CONCLUSION: Conclusions: In children with malignant tumors, during antitumor therapy, there is a decrease in the level of hygiene of the oral cavity, accompanied by morphological destructive changes in the integumentary epithelial layer of the gingival margin. The severity of these disorders depends on the type and dose of cytostatic drugs, which should be considered in the formation of treatment and prevention measures for them.

IMPREGNATION OF ORAL MUCOSA OVER IMPACTED TEETH BY SUBPOPULATIONS OF MACROPHAGES M1 AND M2.

OBJECTIVE: The aim: Of the study is to research quantitative parameters of mucous membrane macrophages populations M1 (CD68+) and M2 (CD163+) over vestibularly and palatally impacted teeth. PATIENTS AND METHODS: Materials and methods: A group of 21 people aged from 10 to 16 years was formed to conduct the research. Clinical situation according to diagnostic criteria was identical in all the patients. The group was divided into two groups - control and experimental, which in their turn were fragmented into two subgroups. Immunohistochemical studies of mucosal biopsies were performed in accordance with the recommendations for selection. RESULTS: Results: Study of ratio of CD68+/CD163+ cells revealed imbalance in individuals with vestibularly impacted teeth due to higher infiltration density of CD163+ (p<0,05), compared to CD68+ of control group. In individuals with palatally impacted teeth, ratio of CD68+/CD163+ increased 3,6 times, as well as compared with control group, but due increased infiltration density of CD68+. CONCLUSION: Conclusions: In the epithelium of oral mucosa located over impacted teeth, both on vestibular and palatal surface, number of CD 68+ and CD163+ cells had no significant differences compared to control group. In biopsies of the lamina propria of mucosa over vestibularly impacted teeth, the ratio M1/M2=0,91±0,11 (p<0,05) decreases, with predominance of macrophages CD163+ subpopulation activity, and over palatally impacted teeth balance of M1/ M2 macrophages elevated (M1/M2= 2,10 ± 0,32, p<0,05), due to increased infiltration density of CD68+.

OBJECTIVE: The aim: The study of the presence of disorders in the ante- and postnatal periods of development of children from 2 months to 15 years with chronic parenchimatic parotitis, which may affect its course. PATIENTS AND METHODS: Materials and methods: It has been examined and treated 88 children, aged from 2 months to 15 years with chronic parenchimatic parotitis, and their mothers were interviewed, who indicated the pathological course of pregnancy, childbirth and indicated the type of breastfeeding babbies. The scope of the survey included general, additional methods, consultations by related specialists and statistical processing of results. RESULTS: Results: 88 children with the exacerbation of chronic parenchimatic parotitis were examined (42 - (47%) with active course and 46 - (53%) with inactive). The exacerbation occurred on the background of acute infectious processes or coincided with the exacerbation of one of the chronic diseases. The first manifestations occurred in spring (55%) and autumn (36%) periods, 44% of children were hospitalized with other diagnoses. The presence of pathological conditions during pregnancy and birth defects in their mothers were recorded more often 3,5 and 3,3 times, respectively, compared with control. 70% of children received mixed and artificial feeding and were more likely to become ill. CONCLUSION: Conclusions: The severity of clinical manifestations of inflammation and disorders of the general condition depended on the activity of the course of chronic parenchimatic parotitis and were more pronounced when active. During the remission period, no apparent clinical manifestations were detected in 72% of observations, however, in 28%, the identified signs indicated a latent course, which required additional treatment and rehabilitation measures.

BAD HABITS AND THEIR IMPACT ON STUDENTS' HEALTH.

OBJECTIVE: The aim: Is to investigate the bad habits of the students of higher education institutions and their impact on health. PATIENTS AND METHODS: Materials and methods: The research of the students' bad habits was conducted at Polissia National University and Zhytomyr Ivan Franko State University in 2014-2019. 647 students of different specialties between the ages of 17 and 23 were interviewed. The research methods included theoretical methods (the analysis and generalization of literary sources, the evaluation of the quality of students' performance in classes, the study and analysis of the medical records of students); empirical methods (pedagogical observations, questionnaires, surveys); the methods of mathematical statistics. RESULTS: Results: The study found that 32.4 % of male students and 14.9 % of female students smoke. It was defined that male students of the special education department smoke the most - 37.7 %; 32.5 % and 27.1 % of the male students of the main and sports departments smoke respectively. Among female students, 18.4 % of the students of the sports department, 14.6 % - of the main department and 13.4 % - of the special department smoke. The study determined that 2.7 % of both male and female students of the first year of study drink alcohol almost every day, 3.7 % - 2-3 times a week, 18.2 % - once a week, 66.0 % - only on holidays. Besides, the research indicated that some students use drugs. It was found that the students know that smoking, alcohol, and drugs are harmful but cannot or do not want to get rid of these bad habits. CONCLUSION: Conclusions: The study established that the environment of students is unfavorable for the activation of the healthy lifestyle components; it contributes to the spread of bad habits, the consequences of which students do not realize fully. Many students do not have a need to take care of their own health.

Clinical-morphological characteristics and peculiarities of treatment of paraururicular fistulas in children.

OBJECTIVE: The aim: Determining the frequency of occurrence of paraauricular fistula in children and comparing the results of their own experience regarding their clinical manifestations, treatment principles and morphological features with existing scientific data. PATIENTS AND METHODS: Materials and methods: The results of a comprehensive examination and surgical treatment of 25 children with paraauricular fistulas. RESULTS: Results: Most often, para-auricular fistula was observed in infants 22 - (88%). In 18 persons (72%), they were unilateral, in 10 - (40%) hereditary. In 8 - (32%), fistula was diagnosed immediately after birth. In 17 - (68%) the pathology was not clinically manifested, but was an accidental finding during the next medical examination. Morphological research has shown that congenital paraauricular fistula is a formed canal intimately associated with the epithelium and cartilage, and the presence of epithelial lining on the fistula wall with constant support of the inflammatory process makes it impossible to heal even against the background of multicomponent treatment. CONCLUSION: Conclusions: Due to the topographic-anatomical localization, features of the clinic of the born fistula, surgical treatment does not always allow to achieve the desired results, and requires repeated interventions during recurrence. It is possible to prevent recurrence by the extensive use of additional diagnostic manipulations before surgery and careful wound control during surgical procedures.

Impact of polychemotherapy on the oral soft tissues in children with malignant abdominal tumors.

OBJECTIVE: Introduction: According to modern standards of treatment of malignant neoplasms conducting polychemotherapy requires up to 90% of cancer patients. However, in addition to the expected cytotoxic effects, it is accompanied by disorders in dental health in the vast majority of patients. The aim: To study the effect of cytostatics on soft tissues of the oral cavity in children with malignant tumors of the abdominal cavity. PATIENTS AND METHODS: Materials and methods: Material for writing this scientific work served as a synthesis of results for 25 people aged 7 to 15 years with malignant tumors of the abdominal cavity, in which a comprehensive oral examination was performed to determine the manifestations of dental toxicity cytostatics. RESULTS: Results: At the end of the first course of chemotherapy, all patients had dry redness of the lips, 20 - (80,0%) with eruptions, in 18 - (20,0%) erosion. The Green-Vermillion, PMA, and PBI indices grew by 1,8; 7 and 3,3 times respectively. In cytograms with buccal epithelium an increase in the number of cells of polymorphic sizes and forms with signs of gidropic dystrophy was found. The nuclear-cytoplasmic ratio decreased by 1,4 times compared with the primary examination. CONCLUSION: Conclusions: This situation creates the preconditions for the development of inflammatory process in the tissues of the oral cavity and requires the use in this category of patients of a substantiated pathogenetic correction of existing disorders.

Optimization of surgical-orthodontic treatment tactics in patients with impacted teeth.

OBJECTIVE: Introduction: Impacted teeth is complex anomaly of teeth eruption that requires a balanced approach not only in the differential diagnosis of its forms, but choice of rational methods of treatment. The aim: Optimization of the tactics of orthodontic-surgical treatment of patients with impacted teeth based on the development and implementation of computed tomographic indices (KT) and photometric indices (FM) of opening of surgical access (OSA) to crowns of impacted teeth. PATIENTS AND METHODS: Materials and methods:The results of treatment of 48 patients with delay of permanent teeth eruption have been analyzed. For an objective assessment of treatment results, a group of 24 (aged from 9 to 19 years old ) was formed. All 24 patients had typical clinical situation. RESULTS: Results: Orthodontic correction of patients envisaged, first of all, the elimination of obstacles in the way of teeth eruption, if necessary to provide space in dental arch and simultaneous treatment of associated bite malocclusions. Surgical exposure of impacted tooth crown was carried out and at the same time a triangular shaped guiding channel was formed, base of channel was at the impacted tooth and its angle finished into the dental arch. Precise dimensions and depth of the channel were preliminary planed on computed tomography slices with 3D reconstruction. Mean values of CT width (7,13±0,54mm), and length (6,42±0,78mm) of OSA and CT index (130,79±8,19%) of OSA to impacted teeth crowns were determined. CONCLUSION: Conclusion: To improve the quality of diagnosis and optimization of methodological approaches to treatment of patients with teeth impaction, we have proposed CT and FM OSA indices to the crowns of impacted teeth. The developed indices serve as specific reference points for optimization of diagnostic process, for reducing of probability of repeated surgical interventions and choosing the optimal path for instrumental orthodontic treatment of patients with impacted teeth.

Diagnostic information of computed tomography of the upper jaw in patients required implant rehabilitation.

OBJECTIVE: Introduction: Dental implantation in conditions of bone deficiency in the loss of lateral group of teeth of the upper jaw is impossible without the maxillary sinus floor augmentation. Preparation for surgical intervention requires a thorough assessment of the anatomical features of the sinus, relationship between the sinus and adjacent teeth, detection of foci of chronic infection of the Schneiderian membrane. In the complex of the objective methods of investigation, computed tomography is the most informative approach to study the state of the bone and soft tissue structure of the sinus. The aim of the paper is to evaluate the state of the bone structures and maxillary sinus membrane to determine the technique for selection the optimum alternative for management of patients, who required sinus lift, based on the computed tomography. PATIENTS AND METHODS: Materials and methods: Computed tomographic examination of 206 patients with bounded and free-end edentulous spaces in the lateral area of the upper jaw was carried out over a period of 2010-2017 to evaluate the appropriateness of sinus lift approach and selection of its technique. The state of the bone tissue and presence of the auxiliary septa, intranasal structures, including ostiomeatal complex, presence of edema and exudates, lesions of the mucosa, as well as the state of ostium maxillaris has been estimated. RESULTS: Results: In the projection of the maxillary sinus the thickness of the bone tissue ranged within 1 mm to 10,5 mm; the density of bone tissues was of the D3-D4 type. Inflammatory events were detected in 60,1&, including: thickening of the mucous membrane on the right and on the left (40,6& and 41,1&, respectively), the total edema (8,6& and 9,7&, respectively). Bilateral thickening was found in 38,8&, and bilateral total edema in 28,0& of cases. Remnants of the filling material were found in 1,4& of sinuses on the right and in 2,8& on the left. Bone septum was visualized on the right in 18,8&, and in 17,4& on the left, bilateral in the 31,8&. Cystic masses were detected on the right in 4,2& of cases and in 6,2& on the left, bilateral in 16,7&. CONCLUSION: Conclusions: Computed tomographic examination provides thorough evaluation of the parameters of the bone tissues, state of mucous membrane and peculiarities of architectonics of maxillary sinuses at the pre-implantation stage.
