The infections caused by orthohantaviruses were already known in the Middle Ages as “English sweats.” There are two main diseases caused by these viruses – HPS (hantavirus pulmonary syndrome) and HFRS (hemorrhagic fever with renal syndrome). Rodents are the main reservoir of these microorganisms, and humans usually catch them by inhalation, as a result of contact with secretions and droppings of carriers. HPS is characterized by a sudden onset, and symptoms include primarily cough, fever and difficulty breathing, and in extreme cases – respiratory failure and cardiogenic shock. HFRS begins suddenly and the main manifestation includes fever, renal failure, hemorrhage, hematuria and proteinuria, as well as shock. At present, anti-hantavirus therapy with proven effectiveness does not exist. A key role in the treatment is resting lifestyle, electrolyte control, fluid therapy and prevention of hypotension, and in harder cases – administration of oxygen.

Minimally invasive repair of pectus excavatum (MIRPE) technique (the Nuss procedure) is a minimally-invasive method that is commonly used in the treatment of pectus excavatum. An allergic reaction to the metal alloy bar that is implanted in the thorax during the procedure is a reported complication. We briefly review current literature concerning epidemiology, mechanisms and research results of allergic reactions after Nuss bar implantation. This allergic reaction occurs in approximately 2.7% of patients and is caused by metals used in the medical implant. The most common symptoms include fever and skin lesions such as allergic dermatitis. Elevated levels of C-reactive protein is a frequent finding in laboratory tests. In order to minimize the risk of such complications, taking a detailed allergy-based medical history and conducting allergy tests, i.e. patch test are required. Allergic reactions can be managed with conservative treatment such as general or topical glucocorticosteroid therapy and antihistamine agents. Severe allergic reactions can be addressed by implant revision, replacement of the steel bar with a titanium substitute or removal of the stabilization at all. Although the risk of an allergic reaction to titanium is smaller it still exists, the titanium substitute is not routinely used due to its higher cost and lesser plasticity which has a negative impact on matching a stabilizing bar during the surgery. Surgeons treating pectus excavatum should remember about the possible allergic reactions after implantation of the metal bar and be familiar with methods of diagnosis and treatment of those complications.

Introduction: Wendigo psychosis is considered an endemic psychiatric disorder associated with culture. It manifests through compulsive, strong attacks of cannibalistic behaviors. It mainly concerns Algonquian: Cree tribes and people living in the Northern Ojibwa area. Material and methods: In our article, we have collected available publications on Wendigo’s psychosis. This area included Internet databases: PubMed and Google Scholar, from the first reports on the disease to the latest information. Due to culture-bound syndromes and the rarity of occurrence in the present time at work, we focused not only on symptoms, treatment or diagnosis, but also on historical and ethnographic features. Discussion: The first remarks on this disorder derive from the Powhatan dictionary which was used by the Algonquian tribe. In the 1960s there were 70 cases of the disease, but the available epidemiologic data is poor. There are many legends about the mythical creature Wendigo and its likeness is repeatedly used in popular culture. Most of the symptoms exhibited by those suffering from this dysfunction is related to famine and chronic loneliness, e.g. apathy, neurosis. Summary: The treatment of the psychosis in the past was based on folk beliefs, as well as homicide. Modern medicine offers a wide spectrum of antipsychotic drugs whose use is focused on the elimination of side effects. Pharmacotherapy consists in administering to the sick drugs from the group of benzodiazepines or antipsychotic agents of both the first and the second generation.
