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.

FREQUENCY, STRUCTURE AND CLINICAL MANIFESTATIONS OF THERMAL BURNS OF THE JAW-FACIAL AREA IN CHILDREN.

OBJECTIVE: The aim: To establish the frequency, structure and features of the clinical course of facial and neck burns in children. PATIENTS AND METHODS: Materials and methods: During 5 years, 78 patients aged from 6 months to 15 years with isolated burns of the face and neck and in combination with lesions of other anatomical areas were treated. In the dynamics of observation of patients were used classical methods of examination, and in their treatment we followed the protocol of medical care for this category of patients. RESULTS: Results: Thermal injuries of the face and neck accounted for 12.6% of the total number of patients with burns. Their isolated lesion was 26.9%, and in combination with other areas it was 73.1%. The most frequently affected were children of nursery, primary school and preschool age, with a predominance of rural residents (52.6%), mostly boys (78.0%). Anesthesia support had to be used in the treatment of 24 patients (30,8%). The features and nature of the burns depended on the relief of the face and the most damaged are its protruding parts.

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.
