Granuloma annulare (GA) is a benign inflammatory skin disease that presents with erythematous papules and annular plaques. The pathogenesis of GA remains unknown and may potentially involve type 1 T helper cell (Th1)-mediated delayedtype hypersensitivity reaction. GA is associated with many conditions such as malignancy, trauma, thyroid disease, diabetes mellitus, and viral infection. The role of biological treatment is under investigation. In this article, we present a case of GA development following systemic treatment of psoriatic arthritis in a 59-year-old patient; golimumab therapy resulted in the successful treatment of both psoriatic arthritis and GA. This is the first case report describing GA therapy using golimumab.

Introduction: An increasing number of publications describing dermatoses associated with Coronavirus disease 2019 (COVID-19) have shown differences in the morphology and incidence of dermatoses in children compared to the general population. Material and methods: Among 22 selected full-text articles, dermatoses associated with COVID-19 have been described in 196 children (average age: 12.57 years). Dermatoses were the only symptom in most patients (n = 134; 68.4%). RT-PCR tests of nasopharyngeal swabs confirmed SARS-CoV-2 infection in only 18 cases (n = 18/69; 26.1%). Results: Dermatoses described include chilblain-like lesions (n = 173; 88.3%), maculopapular rash (n = 16; 8.2%), erythema multiforme-like lesions (n = 12; 6.1%), varicella-like exanthema (n = 1; 0.5%), and urticaria (n = 1; 0.5%). Conclusions: This publication aims to summarise existing data on dermatoses and to draw attention to how identification of dermatological symptoms in paediatric patients can provide a quick and reliable indicator of COVID-19.

Neuroendocrine neoplasms (NENs) are a heterogeneous group of rare tumours derived from peptidergic neurons and specialized neuroendocrine cells capable of secreting various peptides or amines. These cells may be present in endocrine tissue or diffused in the tissues of the digestive or respiratory system. The article reviews the characteristic features of NENs, with particular emphasis on skin manifestations, such as necrolytic migratory erythema (NME), tongue inflammation, angular cheilitis, venous thrombosis and alopecia in glucagonoma; "flushing", "lion face", pellagra skin symptoms, "scleroderma-like features without Raynaud's phenomenon" in carcinoid tumours. The paper also presents the clinical picture of the neuroendocrine tumour of the skin -Merkel cell carcinoma. The aim of this study was to draw attention to the need for precise and comprehensive diagnosis of the patients, with particular emphasis on skin lesions as a revelator of neuroendocrine tumours. This management allows for the early implementation of appropriate treatment.

The COVID-19 pandemic spread to almost all countries in the world within a few months, necessitating changes in medical care for patients with SARS-CoV-2 infections as well as patients with various chronic diseases. Ensuring the safety of medical staff and patients in hospitals specializing in infectious diseases is a major logistical challenge. Psoriasis patients treated with immunosuppressive medications, including those under biologic therapy, are a special group. Many scientific societies do not recommend discontinuing therapy in patients without symptoms or confirmation of SARS-CoV-2 infection despite the potentially higher risk of respiratory tract infections in this patient population. Based on our own experience, we present the organization of the biologic therapy within the unit of a Single Specialty Infectious Hospital.

Introduction: Post- thrombotic syndrome (PTS) is the most common complication of deep vein thrombosis (DVT), and develops in 20–50% of patients after a proximal DVT. Balneotherapy and hydrotherapy is justified in treatment of primary or post-thrombotic chronic venous insufficiency (CVI). M aterial: A review of articles was done in electronic databases Pubmed and Medline by keywords: postthrombotic syndrome, chronic venous insufficiency in conjunction with balneotherapy, hydrotherapy, kinesitherapy, coagulation. Results: Main risk of PST is considered as extensive proximal character of DVT, pre-existing CVI, older age, high body mass index, pre-existent varicosities. PTS refers to clinical manifestations of CVI, and is common cause of unilateral CVI. The thrombus itself may lead to venous valves destruction and reflux. The Villalta PTS scale may define and classify the severity of PTS Venous leg ulcers is the most advanced clinical manifestation of the disease. Prevention of PTS begins with prevention of initial and recurrent DVT includes use of compression stockings and anticoagulant medications. Treatment guidelines recommend anticoagulant therapy - five days with heparin followed by three months of oral anticoagulant after acute event, with subsequent long-term of extended therapy depending on patient’s risk of recurrence. Recent clinical trials indicate that the use of new anticoagulants (NOAS) reduces the incidence of PTS. Ultrasound compression test of the leg veins evaluates the degree of obstruction by clots. Medical therapy of CVI has still not efficient. Carbon dioxide baths and ozone baths have favorably affect hemostasis system. However there are only a few controlled studies evaluating effects of balneotherapy in primary and post-thrombotic CVI. The favorable effect of these mineral baths may result from both hydrostatic effects as well as the contribution with specific chemico-physical properties. The controlled trials (in patients with C3 -C5 stage) shown that balneohydrotherapy and kinesitherapy have decreased signs and symptoms in patients with primary and post - thrombotic CVI. Conclusions: The Health Resort treatment of patients with CVI in the mechanism of post-thrombotic syndrome should be preceded by evaluation of the venous system of the lower limb by compression ultrasound. Balneotherapy and hydroteraphy seem to be effective and safe procedures even in patients with advanced primary and post-thrombotic CVI stage.
