Lateral epicondylitis: tendinitis or tendinosis?

Lateral epicondylitis is a common pathology of the musculoskeletal system resulting from repeated microtrauma of the extensor muscles of the forearm and their tendons. Lateral epicondylitis was previously thought to be tendinitis, which is an inflammatory reaction in the tendon. However, histopathologically, it has been shown to be low in inflammatory elements: macrophages and neutrophils. Thus, it is now believed that this pathology is a tendinosis, which is defined as a degenerative rather than an inflammatory process

Shock wave therapy evaluation in the complex treatment of athletes with lateral epicondylitis

Objective: to evaluate the effectiveness of shock wave therapy in the complex treatment of athletes with lateral epicondylitis in comparison with standard methods of treatment.Materials and methods: On outpatient treatment in the period from 2019 to 2022. There were 168 athletes diagnosed with Lateral epicondylitis, including 78 women (46.4 %) and 90 men (53.6 %) aged 20 to 45 years. The mean age of the patients was 31.48 ± 6.72 years. The average duration of the disease was 33.68 ± 28.17 days. To achieve the set goals and objectives, a prospective randomized controlled clinical trial was conducted. We used a clinical examination of patients, a study of carpal dynamometry of the affected arm, an assessment of the level of pain and quality of life using the QuickDash and Patient-Rated Tennis Elbow Evaluation (PRTEE) scales, statistical research methods, as well as the use of standard treatment for lateral epicondylitis and radial shock wave therapy with an assessment of effectiveness one month after treatment.Results: shock wave therapy in the complex treatment of athletes with lateral epicondylitis, compared with standard methods of treatment, improved the quality of life and reduced pain three weeks after the start of treatment and has a more pronounced effect in the long term (p < 0.05); allowed to reduce the intensity of the signal from the bone tissue (trabecular edema) according to the results of magnetic resonance imaging.Conclusion: the expediency of using shock wave therapy in the complex treatment of athletes with lateral epicondylitis is substantiated, which makes it possible to recommend its use in practical healthcare

Исследование олеогеля на основе компонентов Helianthus annuus L. и Rosmarinus officinalis L. в качестве фритюрного жира

The aim of this study was to study the oxidation resistance and functional properties of oleogels based on high oleic oil and wax from Helianthus annuus L. with the addition of a natural complex antioxidant — an extract from Rosmarinus officinalis L. and lecithin from Helianthus annuus L. — when used as a frying medium for French-fries. High oleic sunflower oil was structured into an oleogel with sunflower wax at a dosage of 5%. Studies were carried out to determine the possibility of replacing the synthetic antioxidant tert-butylhydroquinone at a dosage of 200 mg/kg with a natural antioxidant based on rosemary extract and sunflower lecithin in an oleogel with a defoamer. It was determined that the introduction of sunflower wax increased the induction period of high-oleic sunflower oil by 1.6 times, and the additional introduction of defoamer and antioxidants increased this figure by 1.8–2 times. The rate of accumulation of oxidation products in oil, which is characterized by the level of total polar materials, decreased when wax and antioxidants were added. The degree of thermal oxidation most quickly reached the limit value in oil without additives; in oleogels, it significantly decreased. The introduction of sunflower wax into oil contributed to a noticeable decrease in the absorption of oil by potatoes: fried in oleogel, it absorbed 34–38% less oil than fried in oil without additives. The addition of 0.07% rosemary extract with sunflower lecithin to the oleogel increased the operating time of frying oil by at least 2 times, approximately the same as that of the oleogel with tert-butylhydroquinone. This makes it possible to replace the synthetic antioxidant in deepfrying oleogel with natural rosemary extract with sunflower lecithin. The developed oleogel is a frying oil that has a longer service life and allows you to get fried products with a lower amount of fat.Целью настоящего исследования являлось изучение устойчивости к окислению и функциональных свойств олеогелей на основе высокоолеинового масла и воска из Helianthus annuus L. с вводом натурального комплексного антиокислителя — экстракта из Rosmarinus officinalis L. и лецитина из Helianthus annuus L. — при использовании их в качестве жарочной среды для картофеля-фри. Высокоолеиновое подсолнечное масло было структурировано в олеогель подсолнечным воском в дозировке 5%. Проводили исследования по определению возможности замены синтетического антиокислителя трет-бутилгидрохинона в дозировке 200 мг/кг на натуральный антиокислитель на основе экстракта розмарина и подсолнечного лецитина в олеогеле с пеногасителем. Было определено, что внесение подсолнечного воска увеличило индукционный период высокоолеинового подсолнечного масла в 1.6 раза, а дополнительный ввод пеногасителя и антиокислителей увеличил данный показатель уже в 1.8–2 раза. Скорость накопления продуктов окисления в масле, характеризующаяся уровнем общих полярных веществ, при внесении воска и антиокислителей снижалась. Степень термического окисления быстрее всех достигла предельного значения в масле без добавок, в олеогелях она заметно снижалась. Введение в масло подсолнечного воска способствовало заметному снижению впитываемости масла картофелем: обжаренный в олеогеле, он впитывал на 34–38% меньше масла, чем обжаренный в масле без добавок. Внесение в олеогель 0.07% экстракта розмарина с подсолнечным лецитином увеличивало время эксплуатации фритюрного жира не менее чем в 2 раза примерно также, как и у олеогеля с трет-бутилгидрохиноном. Это дает возможность произвести замену синтетического антиокислителя в олеогеле для фритюра на натуральный экстракт розмарина с подсолнечным лецитином. Разработанный олеогель является фритюрным жиром, имеющим более длительный срок эксплуатации и позволяющим получать обжаренные продукты с более низким количеством жира

Features of case management with neuromuscular disease during COVID-19. Clinical impression

The new COVID-19 coronavirus infection, which has become a pandemic, is a very dangerous disease, the clinical picture of which can vary from mild to extremely severe forms of the course. Currently, there are no complete data on the pathogenetic mechanism of SARS-CoV-2, but there are extensive data on the probable risk factors for the development of extremely severe forms of COVID-19. The study of such factors becomes most suitable in terms of preventing their development and influence on the course of the disease in individuals with compromised immune systems and patients with impaired neuromuscular transmission. The article describes two clinical cases of extremely severe COVID-19 in patients with impaired neuromuscular transmission. Based on the analysis of the course of diseases, the conclusions are made about the possible aggravation and mutual activation of the immunopathological process with the launch of the cascade mechanism of the cytokine storm. An assumption has been made about the influence of human leukocyte antigen (HLA) on the severity of COVID-19, which is confirmed by a positive dynamics against the background of administration of IVIG, glucocorticosteroids (GCS), virusinactivated plasma and extracorporeal detoxification methods
