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.

Adverse factors that can affect on the course of chronic parenchimatic parotitis in children.

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.

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.

Insect bites as the cause of infectious and allergic inflammatory processes of the maxillofacial area in children.

OBJECTIVE: Introduction: The part of purulent inflammatory processes (IP) of the maxillofacial area (MFA) as a result of insect bites are increased. The aim: To attract attention of the medical community to the problem of the complexity of the diagnosis and treatment of these dermatogenic forms of IP MFA. PATIENTS AND METHODS: Materials and methods: The work is based on the results of 5 year observations of 42 patients with acute IP MFA arising after insect bites, their comprehensive examination and treatment. CONCLUSION: Conclusions:1. IP of MFA, arising as a result of insect bites, is a very urgent problem of pediatric surgical dentistry and require an individual approach in the diagnosis and treatment of patients. 2. A large role in preventing the occurrence of these nosological forms is given to medical workers, a sufficient organization level of sanitary and educational work, and the treatment of such cases becomes a common task of doctors of different profiles. However, much depends on the parents, their level of responsibility and competency, ensuring of timely treatment and provision of qualified medical care to children, preventing the development of severe complications. 3. The issues related to the etiopathogenesis of this pathology require profound scientific research.

[Statistical information about the inflammatory processes of the jaw-facial part in children].

OBJECTIVE: Introduction: The acute and chronic inflammatory processes prevail in the structure of the dental surgical diseases in children. Notably, various forms of lymphadenitis, adenophlegmon and odontogenous osteomyelitis dominate in the specialized surgical units; however, it is not possible to resolve a number of organizational problems without clear understanding of the statistical situation. The aim: The paper is aimed at the analysis of the incidence rate of major nosological forms of the acute suppurative inflammations of the maxillofacial area in children for the prospective planning of arrangements to provide them with high-quality specialized care. PATIENTS AND METHODS: Materials and methods: The paper involves findings of comprehensive examination and treatment of 537children with acute purulent lymphadenitis, adenophlegmon and odontogenous osteomyelitis that was carried out within 6 years. RESULTS: Results: The resulting clinical data have shown that three abovementioned nosological forms of the disease accounted for 42% of the overall number of the inpatient dental patients and 11% of the total number of children with acute surgical pathology. Out of 537 patients, 240 patients (44.8%) with acute purulent lymphadenitis, 150 (27,9%) patients with adenophlegmon and 147 (27.3%) patients with acute odontogenous osteomyelitis have been observed (318 (59,2%) boys and 219 (40,8%) girls aged from 2 months to 15 years). The study of the past history of the disease has established that in the majority of patients burdened premorbid history and occurrence of concomitant chronic general somatic diseases was presented prior to the onset of acute inflammation. CONCLUSION: Conclusions: The factors, mentioned above, greatly contributed to increase in protective-adaptive properties of child body and create the prerequisites for the formation of pathological symptomocomplex in children, which can be implemented even in the minimal effect of antigen load on the tissues of maxillofacial area. Such situation requires a balanced multidisciplinary approach to the planning of preventive measures in this category of patients at all stages of the observation.
