Introduction and purpose: The impact of electronic devices on our daily lives is becoming increasingly significant. The contemporary generation of young people is growing up in a world where smartphones, tablets, computers, and other electronic devices are widely available and utilized. Scientists are contemplating the challenges posed by excessive exploitation of electronics on the health of young individuals. The aim of the article is to present the harmful effects of using electronic devices before sleep in young people, considering medical aspects such as sleep disorders and their influence on overall psychophysical health. Summary: Electronic devices negatively affect the sleep of young people by reducing sleep time and delaying the sleep onset phase. The main problem is the use of electronic devices without time limits. In the era of technology, it is significantly important to raise awareness among young people about the importance of sleep hygiene and how blue light emitted by electronic devices affects its quality.

Introduction and purpose: Coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), had been spreading rapidly throughout the world, mainly affecting respiratory system. Except pulmonary symptoms, skin lesions might also occur. The precise percentage of patients with confirmed COVID-19 who presented cutaneous manifestations is still unknown (0.2% - 20.4%). Part of the skin lesions might be drug-induced. Brief description of the state of knowledge: Cutaneous manifestations in the course of the coronavirus disease could be divided into six main groups: maculopapular rash, urticarial lesions, chilblain‐like lesions, vesicular eruptions, petechial/purpuric lesions and livedoid lesions. The most common skin lesions are maculopapular eruptions (47%). Trunk is the most affected location, whereas pruritus is the most frequent additional symptom among patients with skin lesions associated with coronavirus disease. These lesions appear mainly in elderly patients except pseudo chilblains which are present among children and young adults with SARS-Cov-2 infection. The majority of cutaneous manifestations occur after COVID-19 systemic symptoms, but the appearance of vesicular lesions before the respiratory signs was also reported. Cutaneous manifestations resolved spontaneously at different times, ranging from a few days to 2-4 weeks. Moreover, patients with severe course of COVID-19 with maculopapular rash have better prognosis (2% mortality rate) in comparison to patients who developed livedoid lesions in course of the coronavirus disease (10% mortality rate). Summary: Pseudo-chilblains and vesicular lesions are the most specific cutaneous manifestations of coronavirus disease. Healthcare professionals should pay attention to patients who present skin symptoms in the course of COVID-19. Cutaneous manifestations can facilitate the doctor the diagnosis and even estimate the severity of coronavirus disease.

Introduction and purpose: Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic disease in children, involving not only joints but also internal organs, skin, and eyes. It is diagnosed in children under the age of 16 when symptoms last longer than six weeks. The ILAR classification includes several subtypes such as oligoarticular, polyarticular (RF-positive and RF-negative), systemic (sJIA), psoriatic, and enthesitis-related arthritis. Systemic JIA is characterized by fever and rash, while the oligoarticular form often coexists with positive ANA antibodies and carries a high risk of chronic uveitis. New subtypes have been added in recent years, such as early-onset ANA-positive JIA. Imaging, including X-ray, MRI, and ultrasound, plays a crucial role in assessing disease progression, especially in the hip, knee, and temporomandibular joints. Treatment involves a multidisciplinary approach and includes NSAIDs, intra-articular and systemic glucocorticoids, non-biologic DMARDs (especially methotrexate), and biological therapies. Biologic agents include TNF inhibitors (adalimumab, etanercept, infliximab), IL-1 inhibitors (anakinra, canakinumab), IL-6 inhibitor (tocilizumab), T-cell inhibitor (abatacept), and B-cell therapy (rituximab). These targeted treatments improve disease control, reduce joint damage, and enhance quality of life, enabling many patients to achieve remission and prevent long-term disability.

Introduction and Objective: Lyme disease is an infection caused by Gram-negative,microaerophilic spirochetes of the Borrelia genus, transmitted to humans through the bite ofan infected tick, which serves as the vector of this disease. It is one of the most frequentlydiagnosed tick-borne illnesses worldwide, with a rising incidence rate. Notably, childrenrepresent an increasingly affected population, emphasizing the need for focused attention onpediatric manifestations and management.Brief Overview of Current Knowledge - Lyme disease progresses through three clinicalstages: early localized, early disseminated, and late stage. Each phase presents withcharacteristic clinical manifestations. The early localized stage typically features erythema migrans, most often appearing onthe scalp, neck, shoulders, legs, or lower back. The early disseminated stage is marked by flu-likesymptoms, lymphadenopathy, arthralgia, myalgia, cranial nerve palsies—mostfrequently involving the facial nerve (cranial nerve VII) —ocular involvement,and lymphocytic meningitis. The late stage is characterized predominantly by pauciarticular arthritis, affecting largejoints—especially the knees. In some cases, cardiac manifestations may occur, suchas conduction abnormalities, myocarditis, or pericarditis.This progression underscores the multisystemic nature of Lyme disease and highlights theimportance of early recognition and treatment to prevent long-term complications.

Introduction:  Obesity is one of the most challenging and popular problem in nowadays society. Overweight and obesity are connected with chronic complications, such as arterial hypertension, atherosclerotic cardiovascular disease and type 2 diabetes. Nonsurgical methods of weight loss were not positively conducted in significant part of obese population. It has given a chance to develop part of medicine known as bariatric surgery. Obesity is identified as an risk factor for sexual dysfunction. The aim of this article is to summarize the main findings of studies about the influence of bariatric surgery on sexual functions of obese male patients. Materials and methods: The study is based on medical articles gathered from PubMed database spanning the years 2016-2023 and article from National Institutes of Health and from Nutritionhospitalaria. The research was conducted through the analysis of keywords such as ”Obesity”, „Bariatric Surgery”, Sexual Dysfunction”, „Men”. Results: This review indicated that surgically inducted weight loss could improve sexual function in obese men. It is connected with important increase in IIEF score and serum testosteron level. It is a need for further clinical studies to explore association of sexual function after bariatric surgery.

Introduction and purpose: The impact of aluminum on human life is significant. Scientists have been studying the presence of aluminum in our environment for many years. This research is particularly important given that we live in a world dominated by aluminum, where its diverse applications can expose humanity to this metal from numerous sources. Long-term exposure to aluminum in humans has been connected to changes in behavior, as well as in brain structure and neurochemical processes. The aim of this article is to analyze the current state of knowledge on whether aluminum has a negative impact on human health and the body. Summary: Depending on the dose of aluminum, the following scientific studies suggest that aluminum may impact human health, and regularly exceeding the permissible intake of aluminum throughout life is undesirable, as it leads to an increased risk of health impairment. Therefore, information is available on ways to reduce overall exposure to aluminum.
