Type 1 diabetes is based on apoptosis, which leads to b-cell death. Factors triggering apoptosis processes are very diverse and currently not fully explained. The main role is attributed to genetic and environmental factors. Genetic studies have shown that the inherited propensity for type 1 diabetes is multi-genetic. Environmental factors modify the response to their own antigens, but are probably not necessary to start the autoaggression process. The effect of b-cell destruction is confirmed by the appearance of autoantibodies in the blood. The paper presents a review of the available literature regarding the self-destruction of pancreatic b-cells. The aim of the study was to draw attention to the extremely complicated and still unknown etiopathogenesis of type 1 diabetes by reviewing current literature related to the above topic. The goal is to acquire the knowledge necessary to develop and implement causal treatment for diabetes. At the moment, unfortunately, we do not have safe, innovative therapy methods in the field of diabetes prevention. Intensive research on the etiopathogenesis of type 1 diabetes is an extremely important field of medical research.
Eight untrained men performed 15-s and 60-s high-intensity exercise on a bicycle ergometer. Activities of the creatine kinase (CK) and lactate dehydrogenase (LDH) were measured in blood 3 min and 2, 6, and 24 h after cessation of exercise. The results indicate that anaerobic exercise induces a transient increase in plasma LDH activity and a more prolonged elevation in plasma CK activity. A negative correlation was found between CK activity measured before and 3 min after exercise and mean power, and total external work performed in both test types. A similar correlation was ascertained between pre- and post-exercise CK activity and maximal power output measured in the 60-s test. After the 15-s exercise test, only post-exercise plasma CK activity was negatively correlated with the maximal power output.
Nonmelanoma skin cancers (NMSCs) are the most common malignancies worldwide. Millions of new cases every year present challenge to healthcare systems.Recent years brought numerous new data concerning high dose rate (HDR) brachytherapy (BT) as treatment option for NMSCs. International guidelines do not recognize BT as a method of choice given lack of randomized trials, however many prospective and retrospective studies show promising results. Aim of the study was to present the efficacy of HDR BT, with analysis of its safety and adverse effects based on review of the English published medical full-text papers.Literature review of 13 articles published between 1999 and 2021 was performed. Pubmed and Google Scholar databases were searched on October 2021 using keywords: ([Basal cell carcinoma] OR [squamous cell carcinoma] OR [nonmelanoma skin cancer]) AND (HDR brachytherapy). Fourteen full-text English articles with follow up over 1 year and study group over 50 patients were included into analysis. In analyzed material, 2403 patients received HDR BT. Local control varied between 71% and 99%.Dominant reported cosmetic effect was good or very good. Results were cross-referenced with recent meta-analyses comparing BT to surgical excision, Mohs microsurgery and external beam radiotherapy.Radiodermitis is the main adverse effect of radiation treatment during and after radiotherapy. HDR BT emerges as potentially noninferior treatment method providing very good reported cosmetic outcomes.
Medical history and clinical examination are the most basic elements of medical diagnostics. Clinical examination in the context of dermatology should be combined with the taking and archiving of clinical, dermoscopic and/or video dermoscopic photographs. Dermoscopy is a non-invasive examination and is the recommended method of examining skin lesions. It requires many years of experience and extensive training, and subsequently can be very helpful in the diagnostic process since it allows for a more thorough examination than the unarmed eye. The diagnosis of malignant skin tumours has been significantly improved by noninvasive real-time diagnostic devices. Based on the data from the literature available, we discussed the most commonly used algorithms in the diagnostic process. It should be emphasized that a dermoscopic evaluation may facilitate the diagnosis and early treatment of micromelanoma and basal cell carcinoma. Finally, the role of dermoscopy in the follow-up procedure of oncologic patients should not be forgotten.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
