Guillain-Barré syndrome (GBS) is a rare, acute immune-mediated polyradiculoneuropathy that accounts for an estimated 100,000 new cases annually worldwide. The typical clinical manifestations of the disease are progressive, ascending paralysis, classically involving bilateral upper and lower extremities. In most patients, the acute onset of neurological symptoms is preceded by an infectious respiratory or gastrointestinal illness. The case is presented of a 50-year-old man who was transferred to an intensive care unit from the Department of Neurology, due to a worsening state of bilateral weakness of limbs, with symptoms of respiratory failure and hemodynamic instability. Guillain-Barré syndrome was diagnosed in the previous clinic on the basis of the typical symptoms and results of cerebrospinal fluid, in which albuminocytological dissociation was detected. Furthermore, two weeks previously, the patient had been infected with COVID-19.

Meningococcal meningitis is an inflammation of the meninges caused by Neisseria meningitidis. Clinically, meningococcal meningitis does not differ from other bacterial meningitis. Initially, the symptoms of the disease may be non-specific, such as fever, muscle pain, and weakness, only later do the symptoms typical of meningitis appear. Adolescents and adults have a lower incidence of neck stiffness and altered consciousness than younger patients. The disease is characterized by a rapid onset and progression of symptoms within a few hours. The detection of Neisseria meningitidis in the cerebrospinal fluid allows for the correct diagnosis and appropriate treatment. Antibiotics reduce mortality in meningococcal disease by up to five times. The case is presented of a young adult patient with a history of viral meningitis in childhood who was hospitalized for severe meningococcal meningitis and successfully treated.

Introduction: On the account of the Covid-19 pandemic, many governments around the world have imposed multiple restrictions on public life to prevent the spread of the coronavirus. Social disruption and forced isolation contributed to increased stress as well as increased use of the Internet.Aim of the study: The aim of the study was to investigate the influence of the Covid-19 pandemic on mental health problems, including Internet addiction, and to link Internet addiction with mental health problems such as anxiety, depression symptoms and insomnia.Material and methods: The data for the article was found using the PubMed and Google Scholar websites.Description of the state of knowledge: Internet addiction (IA) is becoming an increasingly serious problem of the modern world. The problem of Internet abuse is associated with various risk factors that are dependent on gender or family relationships, as well as mental disorders.Many studies have confirmed that the Covid-19 pandemic caused negative mental health effects, contributing to increased anxiety and depression symptoms. To reduce stress, people started using the internet more often. This compensatory mechanism can cause even more mental health problems by increasing anxiety, symptoms of depression and insomnia.Summary: Research by many scientists shows that the Covid-19 pandemic is exacerbating the mental health problems associated with IA. Research shows that during the Covid-19 pandemic, it is especially important to be able to manage stress through non-internet-related activities to help prevent IA.
