Omega-3 fatty acids constitute a group of fatty acids with anti-inflammatory and preventive effects against various diseases. Studies in animal models have demonstrated the preventive and therapeutic effects of omega-3 fatty acids after spinal cord injury (SCI) in reducing inflammatory reactions and promoting neuroregeneration. However, studies on the efficacy of omega-3 fatty acids in treatment and prevention after SCI seem to be questionable. This study evaluates potential reasons for omega-3 fatty acid therapy oversight in populations after SCI. Therefore, some of the reasons could cover heterogeneous patient groups in size, level of injury, quality of life assessment, time since injury, no single standardised dose, various follow-up durations and metabolic changes, often insufficient to record. Due to the difficulty of collecting cases for the study, especially in the acute phase after SCI, multicenter, coordinated studies are needed to establish the effects of omega-3 fatty acids on treatment, recovery, and disease prevention in patients after SCI. Although the present results of such studies are still inconclusive, the failure to exploit the potential properties of omega-3 fatty acids in the treatment of patients with SCI solely due to methodological difficulties should be considered a potential waste., (© 2022.

Introduction: As a recurrent disease, periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) syndrome is characterized by episodes of febrile attacks and is often prominent in children under five years of age. However, the etiology of this condition has not been fully understood yet., Materials and Methods: The search in the extensive literature of peer-reviewed articles published from the inception to December 2021 was conducted to identify the relevant studies, using the electronic databases of MEDLINE/PubMed, Embase, Scopus, the Cochrane Library, and the Web of Science., Results: The analysis of complex relationships indicates that inflammatory factors, such as various cytokines and acute-phase proteins (APPs), play leading roles in the pathogenesis of this disease. Accordingly, this article summarizes the current state of knowledge to explain the mechanisms involved in inflammatory responses among patients with PFAPA syndrome and investigate its role in the pathogenesis of this disease. Moreover, the possibilities for further implementation of new therapeutic strategies are pointed out., Conclusion: It is concluded that some pathophysiological processes are associated with immune dysregulation, which itself may be secondary to environmental factors, genetic background, and underlying diseases, including latent infections that multiply inflammatory mediators. elevated inflammatory markers similarly play a significant part in the clinical outcomes of this condition, whose pyrogenic nature is the reason for the development of episodes of febrile attacks in the population of patients suffering from PFAPA syndrome., (© 2022.
