THE OCCURRENCE OF SPORTS INJURIES AMONG PRE-ADOLESCENTS.

Preschool children's harmonious development, cognitive and communicative abilities are enhanced through physical activities in sports, yet sports training and competition pose a risk of injury to children aged three to seven years due to their physiological and psychological features. Although sports injuries in preschool children are not common, they can be undesirable and unavoidable, and fortunately, these injuries are usually reversible. This review article presents data on the physiological features of the developing musculoskeletal system and its relationship to sports injuries in children, which together determine the nature of children's sports injuries. We also present a classification of sports injuries among preschool children, based on the literature, which considers the type, location, and severity of the trauma as estimated by the duration of mandatory missed practice.

THE INCIDENCE OF SPORTS INJURIES AMONG SCHOOL-AGED CHILDREN AND ADOLESCENTS.

It is estimated that approximately one in ten school-aged children experience sports-related injuries annually. These injuries are most common at 12 years of age. Boys are more likely to get injured and more likely to get seriously injured than girls. The probability of injury is greater in contact or high-impact sports, with American soccer accounting for the largest number of injuries, followed by wrestling, basketball, soccer, and baseball. In certain sports, such as horseback riding, women are four times more likely to sustain injuries. The presented literature review details the incidence of various sports-related injuries in adolescents. Sports-related injuries observed in children under the age of 10 are nonspecific and include contusions, mild sprains, and fractures of the extremities, most commonly Salter-Harris fractures (growth plate fractures) or plastic fractures. In young athletes, sports-related injuries of the ligaments or muscles, as well as spinal or head injuries, are rare. This is particularly true during puberty, where growth plate fractures and musculoskeletal injuries occur more frequently.

MEDICAL AND SOCIAL ASPECTS OF PREVENTING SPORTS INJURIES AMONG CHILDREN AND ADOLESCENTS.

Sports injuries among children and adolescents typically involve mild bruises and sprains. However, any sport can cause injuries to the musculoskeletal system. It is crucial to prevent such injuries through proper training and supervision to ensure the safety of young athletes. Therefore, when providing medical care to these patients, physicians must have the appropriate qualifications and skills and take into account the specific nature and location of injuries in each sport. Training programs and performance standards for young athletes should consider participants' biological age, physical and psychological immaturity, rather than their chronological age to prevent serious musculoskeletal injuries in child and youth sports. This review outlines the incidence of sports injuries in adolescents and considers how biological and social factors (factors related to coaches, peers and parents), influence the incidence and nature of injuries in different sports. Coaches and parents, though, have the ability to reduce the risk of injury by selecting suitable sports activities, employing the right equipment, enforcing rules, promoting safe playing conditions, and ensuring adequate supervision. Healthcare providers involved in the prevention and treatment of injuries in young athletes must possess the skillset to diagnose and assess the severity and risk to the athlete's future health and performance.

[PECULIARITIES OF INTERACTION IN THE "PARASITE-HOST" SYSTEM IN HIV-INFECTED PATIENTS WITH TOXOPLASMOSIS: LITERATURE AND CLINICAL CASE REVIEW].

The article presents a review of current literature data on the development of opportunistic toxoplasmosis in patients suffering from HIV infection and a clinical case of an immunocompromised patient with toxoplasmosis. Current information concerning the incidence of toxoplasmosis in Russia and other countries are presented. Special attention is paid to the Toxoplasma gondii interactions with the host cell in HIV-infected people. The mechanism of parasite penetration into the host cell and subsequent modifications that the parasite makes with the occupied cell are analyzed in detail. The significance of the chosen topic is illustrated by the description of a clinical case of toxoplasmosis in an HIV-infected patient. The authors hope that the article will help to attract attention of the professional community to the problem of opportunistic infections in HIV/AIDS carriers, and in particular to the mechanisms of the "parasite-host" interactions in patients with toxoplasmosis.

[Frequency of detection of anaerobic microorganisms in the maxillary sinuses of patients with different forms of chronic maxillary sinusitis].

The aim of the investigation was to determine the frequency of detection of anaerobic microorganisms in the maxillary sinuses of patients with different forms of chronic maxillary sinusitis. 36 patients were examined. Fence clinical material was carried out from the walls of the maxillary sinus with transport tubes Ames during "Operation maxillary sinusotomy." In order to create anaerobic conditions, we used a set of equipment and supplies (manufacturer bio Mérieux, France) of a company bio Merieux in Ukraine--"Company Diaveritas." It was found that the presence of anaerobic infection is not typical for chronic sinusitis of the odontogenic origin. A wider range of pathogens (60%), observed in chronic odontogenic sinusitis with the presence of a foreign body in the lumen of the sinus. In the mixed associations set aside 50% of anaerobic flora.

[Lung perfusion scanning in the comprehensive diagnosis of pulmonary thromboembolism].

The aim of the study was to define the sensitivity, specificity, and diagnostic accuracy of lung perfusion scanning (LPS) in pulmonary thromboembolism (PTE). PTE diagnostic techniques are comparatively assessed. The data on 108 patients with suspected PTE and lung perfusion defects revealed at pulmonary scintigraphy were analyzed. The diagnostic techniques included electrocardiography (ECG), 150 echocardiography, venous ultrasonography, chest X-ray, and LPS. The significant signs of PTE were singled out of 150 ones (history data, complaints, clinical symptoms, instrumental findings, autopsy data); LPS data were analyzed in detail. The sensitivity, specificity, and accuracy of LPS were 95.2, 20, and 77.7%, respectively. It is shown that lung scans should be interpreted, by taking into account X-ray data, and LPS should follow ECG, venous ultrasonography, and chest X-ray.

Usage of antisclerotic diet with fish oil and carotinoides in patients with IND and high blood pressure resulted in positive dynamic of clinic manifestation, blood lipid, coagulogramms, antioxygen and immune status.

[Adrenocortical tumors: mitotic index and nuclear size as criteria for differential diagnosis and prognosis]. / Adrenokortikal'nye opukholi: mitoticheskii indeks i velichina iader kak kriterii differentsial'noi diagnostiki i prognoza.

A comparative study of the mitotic index (MI) and karyometric indices in 15 adrenocortical tumors with clinical syndrome of hypercorticism allowed to distinguish between adenomas and carcinomas. Carcinomas with hypercorticoidism symptoms have common features with inactive carcinomas but are different by lower expression of malignancy criteria (polymorphism, atypia, necrotic foci, capsule and vessel invasion), higher MI, increasing deficiency of cell division and larger nuclear size of tumor cells. Such tumors may be included into the prognostic group of risk.
