When solving this problem, the doctor should take into account the nature, severity and localization of the pathological process, the patient's age, as well as the potency and the safety profile of the drug itself. One of the most common approaches to making the optimal choice of glucocorticoids for topical use, which is designed to reduce potential risks, involves administration the least active drugs at the beginning of the treatment, if they are ineffective, they switch to the use of more active drugs, and further the most active drugs. An obvious disadvantage of this approach is the duration of the procedure of the empirical selection of the drug, which can significantly impede treatment. The emergence of VI generation glucocorticoids, such as mometasone furoate, methylprednisolone aceponate and prednicarbate. The therapeutic potential of these drugs combines high activity and safety of use. It has changed the situation significantly and helped to solve the problem of the safe use of glucocorticoid drugs in pediatric and geriatric practice for the treatment of severe forms of dermatological diseases wich requires administration of the active glucocorticoids. The paper contains an overview of the main classification systems that are applied to glucocorticoids intended for use in dermatological practice, and a short analysis of literary data regarding the experience of the clinical use of VI generation glucocorticoids.

Osteoarthritis is one of the most common dystrophic-degenerative joint diseases, which occurs in 6.4–12.0% of the planet's population. The purpose of the study is to determine modern views on the peculiarities of the pathogenesis of obesity-associated osteoarthritis based on the study of literary sources. An analysis of literature sources was carried out by using the MEDLINE database, Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL, EMBASE, Science Citation Index (Web of Science), Science direct and Scopus by searching: osteoarthritis, obesity, osteoarthritis associated with obesity. The subject of assessment is the pathogenetic relationship of these diseases. The mechanical factor in the development of osteoarthritis is a proven factor in general and in excess body weight in particular. Such a relationship is confirmed by many studies, and the content is that the mediator of the relationship between obesity and OA is biomechanical factors, which are implemented through the redistribution of increased body weight to the supporting joints. The use of modern technological research methods provides an opportunity to deepen the understanding of the complex molecular relationship between OA and obesity. Adipokines have the potential to identify an additional pathogenetic link in the development and progression of OA in obese patients, which forms a potentially new approach in the development and implementation of methods for the prevention and therapy of OA in obese patients. However, views on the correlations of adipokines with OA are quite different (direct, inverse, and even absent), which requires further study.\u0000\u0000Keywords: osteoarthritis, obesity, adipokinins, leptin, apodenectin, resistin.","PeriodicalId":38819,"journal":{"name":"Tokai Journal of Experimental and Clinical Medicine","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74928301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presented work is the result of a blast-induced brain traumatic injury study on a self-developed device.

The ability to learning (food reinforcement) and the spatial memory state (time to search for food, vertical locomotor activity) were studied in the complex maze during the first 5 days of the posttraumatic period. To assess the emotional state, we counted the number and observed the quality of grooming acts. All researches were conducted in compliance with modern standards for humane attitude of animals. The results of our study clearly indicate a violation of spatial memory, which was manifested in the time of searching lengthening of the feeder and in the increase of vertical locomotor activity in the rats of the experimental group, while the animals clearly remembered that they were looking for food. The analysis of grooming showed qualitative changes in the form of incomplete and prolonged acts. Such changes indicate the development of anxiety in rats with mild blast-induced traumatic brain injury. This, in turn, led to deterioration of the spatial orientation and memory formation. Thus, the consequence of a mild blast-induced traumatic brain injury in the acute period is changes in the cognitive function of the brain in the form of deterioration of spatial memory, which was aggravated by a disturbance of emotionality in the form of anxiety.

The aim of this study was to identify the causes and frequency of injuries among pole acrobatics athletes. An online survey was conducted, and 108 participants of mature age (aged 21 to 35 for women and 22 to 35 for men) from Ukraine were selected. The study showed that 87.10% of participants experienced an injury during pole training at least once a year. Most respondents (82.40%) reported bruises, contusions, and soft tissue injuries. 30.55% of respondents reported muscle, tendon, and ligament injuries, 17.59% had joint injuries, and 21.29% had sprains or tears of ligaments. 11.11% of respondents suffered fractures or bone cracks. Only 5.60% had no experience of injury during pole trainings. 75.80% of respondents sometimes experience painful sensations in joints, ligaments, or soft tissues, while 16.70% claimed to feel them constantly. Injuries obtained during pole trainings were treated independently by 63.88% of respondents, 26.85% consulted a traumatologist, and 25% consulted a physical therapist or rehabilitation specialist. Only 3.70% required surgical intervention, and 23.14% sought help from a massage therapist. The most common cause of injury during pole acrobatics training was unsuccessful execution of an element (71.87%). 34.37% of respondents suffered injuries due to falling from the pole.

A deep bite is diagnosing in about 78% of cases with vertical anomalies in the permanent bite. Also, according to the latest research, this pathology occurs most often in Europe, 37.4%. Deep bite is diagnosed more often among men. In addition, there is an increase in the prevalence of deep bite with age in adult patients. In addition, complaints about the musculo-articular complex have become more frequent: pain in the temporomandibular joints, muscle tension, teeth grinding, stronger clenching. All these factors dictate the need for a detailed study of this pathology. The article presents an analysis of modern domestic and foreign literature, which highlights the issues of prevalence, etiology, clinical manifestations, diagnostic criteria and classification of forms of deep bite, its impact on the musculo-articular complex and features of treatment of this pathology in the permanent bite. The reviewed scientific works offer different methods of diagnosis and treatment of deep bite. In particular, the methods of treatment depend on the etiology and nature of deep bite.

The mini-review analyses possible approaches to differentiating the most likely localised granulomatous lesions (granuloma annulare, sarcoidosis, tuberculides, leprosy, and lupus miliaris disseminates faciei) by providing recommendations on possible key clinical and histopathological characteristics. The review is illustrated by a case of a localized granulomatous lesion with features that are atypical but possible for some of the diseases discussed, with the most likely diagnosis of granuloma annulare (clinical course, localization, vertical infiltrates, destruction of elastic fibers, accumulation of mucin, solitary eosinophils). Pathologists need to consider different diagnostic approaches for different types of histological diagnoses, which may require opposite therapies. Therefore, the possibility of infection or foreign material in all types of granulomatous inflammation should be considered and PAS staining and polarized light microscopy should be recommended as basic steps in the examination. Special techniques such as Ziehl-Nielsen or Grocott methenamine silver should be also applied to identify the pathogen if necessary. It is essential to have enough tissue for histological examination, including immunohistochemical staining and polymerase chain reaction.
