Abscess after cardiac pacemaker implantation: A case report.

This is a report of one of the most serious complications of the cardiac pacemaker implantation - infection of the implanted system. We present the case, which was misdiagnosed at the beginning and after cardiological consultation it was decided to immediately remove the peacemaker and transfer the patient to the Cardiological Department.

Trigeminal trophic syndrome associated with neuralgia after ischemic stroke-a case report.

Trigeminal trophic syndrome (TTS) is a rare condition resulting from self-manipulation of the skin after an injury to the trigeminal nerve. We describe the case of a 70-year-old woman who was hospitalized because of erythema, ulceration, and crusts on the right side of her face, accompanied by itching, burning, and irritation forcing self-manipulation of the skin. She had been previously repeatedly treated with antibiotics, acyclovir, and topical medications without any improvement. Her medical history revealed an episode of ischemic stroke in 2016, after which a deformation and partial atrophy of the right ala nasi appeared. Trigeminal neuropathy was confirmed by a neurological consultation. Diagnosis and treatment of TTS requires a multidisciplinary approach. Awareness of this disease should be raised to enable proper diagnosis and management of difficult-to-treat facial ulcers that cannot be explained by common causes.

Cutaneous Eruptions in the Course of COVID-19 Among Geriatric Patients in a Nursing Home in Poland.

Purpose: The aim of this study was to assess the incidence and characteristics of COVID-19 cutaneous manifestations among geriatric patients infected with the SARS-CoV-2 virus. Patients and Methods: Sixty-four nursing home residents in Dobre Miasto, Poland (mean age: 79 years) infected with SARS-CoV-2 were monitored for skin lesions during the epidemic outbreak in 2020. Only five of them presented COVID-19 dermatological manifestation: vesicular (4 cases) and erythematous (1 case) skin lesions, which appeared after the remaining symptoms of the disease had resolved. Results: The average time between COVID-19 onset and cutaneous manifestation was 22 days. Skin lesions persisted in five cases 112, 17, 21,19 and 27 days, respectively, and were often accompanied by pruritus and neuropathic pain. Conclusion: Skin manifestations of SARS-CoV-2 infection might be misdiagnosed or overlooked, particularly among elderly patients with chronic diseases. The recognition of skin lesions due to COVID-19 might improve patients' quality of life by reducing the intensity of symptoms such as pruritus or neuropathic pain.

Etiopathogenesis of dermatitis herpetiformis.

Dermatitis herpetiformis is a rare chronic, autoimmune bullous disease linked to gluten sensitivity with intense pruritus and characteristic skin eruptions. Etiopathogenesis is complex and not fully understood. It is currently considered to be a specific cutaneous manifestation of celiac disease. Genetic, environmental and immunological factors influence both conditions. Exposure to gluten is the starting point of an inflammatory cascade leading to the formation of circulating IgA antibodies against tissue transglutaminase and skin immune IgA deposition followed by skin lesions. Binding of the immune complex deposits of IgA transglutaminases and epidermal antibodies with enzymes in the papillary dermis stimulates complement activation, neutrophil influx, proinflammatory cytokine release and overproduction of matrix metalloproteinases. We have collected current knowledge of the pathogenesis of dermatitis herpetiformis.

Dermatological and Molecular Evidence of Human Cercarial Dermatitis in North-Eastern Poland.

Swimmer's itch or human cercarial dermatitis (HCD) appears as a skin rash caused by an allergic reaction to larval (cercariae) flatworm parasites of the family Schistosomatidae. In our study, two cases of HCD were analyzed; both of them were reported in people swimming in Lake Pluszne. In the summer of 2018, a sample of 397 snails was collected at swimming sites in that area. Five Lymnaea stagnalis (1.9%) were found to host cercariae of bird schistosomes. Positive samples were selected by amplification of the Internal Transcribed Spacers (ITS) gene region. Sequence analysis confirmed that they were homologous with European isolates of Trichobilharzia szidati. The cases reported in this article are the first confirmed cases of HCD in this lake. This study demonstrates that there is a rationale for conducting screening studies of regions with a high recreational potential.

Influence of ustekinumab on body weight of patients with psoriasis: an initial report.

INTRODUCTION: Many recent epidemiological studies have shown the influence of treatment with anti-TNF-α on body mass of patients with psoriasis but there are no reports in the literature on the influence of ustekinumab on that parameter. AIM: To review the effect of ustekinumab therapy on body weight in patients with psoriasis. MATERIAL AND METHODS: The examined group consisted of 11 patients with psoriasis treated at the Department and Clinic of Dermatology in Olsztyn. Patients' body mass and body mass index (BMI) were evaluated prior to the first administration of the ustekinumab dose and at week 28 of treatment (the day of the fourth dose). RESULTS: Body mass increase was determined in 7 patients (64%), on average by 2.27 kg (p < 0.05), and the BMI increased by 3.35% (p < 0.1). CONCLUSIONS: Observing a correlation between ustekinumab application and body mass increase, similar to the treatment with anti-TNF-α preparations, an attempt was undertaken at explaining that correlation by analysing the role of IL-12 and IL-23 in psoriasis pathogenesis. IL-12 and IL-23, by influencing the naïve lymphocytes T and stimulating their diversification towards Th1 and Th17, also, indirectly, cause an increase in TNF-α and other cytokines production (IL-2, IFN-γ, IL-17, IL-10, IL-22). Ustekinumab will then have a significant influence on decreasing the production of cytokines, which are important for metabolism and body mass.
