Article Synopsis
  • The report discusses a serious complication arising from cardiac pacemaker implantation, specifically an infection of the implanted system.
  • The case was initially misdiagnosed, leading to an erroneous treatment approach.
  • After further cardiological consultation, the decision was made to promptly remove the pacemaker and transfer the patient to the Cardiological Department for appropriate care.

Introduction: The skin is the largest organ in the human body and it is also a complex organ. Its protective function is properly maintained due to its continuous renewal. Malignancies develop when the balance between proliferation and cell death is dysregulated in skin cells.

Background: Generalized pustular psoriasis (GPP) is a systemic inflammatory disease that can be severe, debilitating and life threatening. Uncontrolled activation of interleukin (IL)-36 proinflammatory activity may underlie the pathogenesis of GPP. Currently, GPP-specific treatment options are limited.

Article Synopsis
  • - Skin mast cells act as protective cells that respond rapidly to maintain balance in the body, helping to fight infections and facilitate healing when tissue is damaged.
  • - These cells communicate with various body systems, including immune, nervous, and blood systems, by releasing certain substances.
  • - The article examines the role of mast cells in various conditions, including allergies and skin diseases, as well as their involvement in systemic diseases that have significant skin-related symptoms.

Article Synopsis
  • The study aimed to evaluate the occurrence and features of skin issues in elderly patients with COVID-19 in a nursing home in Poland, monitoring 64 residents during the 2020 outbreak.* -
  • Out of the participants, only 5 showed cutaneous manifestations, with the average onset of skin lesions occurring 22 days after COVID-19 symptoms had subsided.* -
  • Recognizing these skin issues is crucial in older patients as it may help avoid misdiagnosis and improve their quality of life by alleviating symptoms like itching and nerve pain.*

Article Synopsis
  • - Drug-induced gingival overgrowth (DIGO) is an adverse effect linked to medications like phenytoin, calcium channel blockers, and cyclosporine A, leading to severe gum problems and potential tooth loss.
  • - The condition is associated with factors such as poor oral hygiene, and it mostly affects young males, especially children and adolescents.
  • - Treatment options include removing tartar and irritants, with gingivectomy being a common surgical procedure for addressing DIGO symptoms.

Introduction: Melanocytes show antigen expressions characteristic for the immune response effector cells, and the immune reactions in the skin, especially those with inflammation background, significantly affect the function of melanocytes. Among the cytokines produced by keratinocytes, the stem cell factor (SCF) plays a leading role in stimulating melanogenesis.

Aim: To compare the expression level of stem cell factor (mSCF, pSCF) and the c-Kit receptor in the centre of the vitiligo patch and in the area of healthy skin adjacent to the vitiligo patch.

Article Synopsis
  • Psoriasis is an autoimmune disease characterized by a disrupted relationship among immune cells, leading to the overproduction of neutrophil extracellular traps (NETs) which are involved in the disease process.
  • The study measured levels of peptidyl arginine deiminase 4 (PAD-4) and TNFα in the blood of psoriatic patients before and after treatment with various therapies, finding elevated levels of both prior to treatment correlated with disease severity.
  • All therapies tested resulted in reduced levels of PAD-4 and TNFα after 12 weeks, with the most significant improvements observed with anti-TNFα treatments, indicating a potential pathway for future therapies targeting PAD-4 in psoriasis management.

Background: The natural course of psoriasis is characterized by the long-term persistence of lesions and a predilection for relapse in the same area. It is caused by the inherence of TRM (tissue resident memory T cells) in apparently healthy skin. These cells are able to initiate an inflammatory cascade and induce relapse of the disease.

Morphea is an inflammatory, immune-mediated disease of unknown aetiology. It is characterised by excessive collagen deposition, which leads to the hardening of the dermis and subcutaneous tissues. The disease is associated with cosmetic and functional impairment, which can affect the patients' quality of life.

Cutaneous adverse drug reactions (CADRs) are among the most common types of drug hypersensitivity reactions. The purpose of this study was to evaluate the clinical spectrum of CADRs and to determine the causal relationship between drugs, comorbidities, cofactors or concomitant symptoms, and cutaneous reactions. A retrospective hospital-based study was carried out over a period of 10 years at the Department of Dermatology, Sexually Transmitted Diseases and Clinical Immunology at the University of Warmia and Mazury in Olsztyn to record various CADRs, comorbidities, cofactors, and the suspected drug in hospitalized patients.

Tetracyclines are a group of antibiotics whose first representative was discovered over 70 years ago. Since then, they have been of great interest in dermatology. In addition to their antibacterial activity, they are able to inhibit metalloproteinases and exhibit anti-inflammatory, anti-apoptotic and antioxidant effects.

Isotretinoin (ISO) is an oral prescription-only retinoid, well known for its acne-treating effect. However, it affects a substantial number of human cell types, causing a broad spectrum of adverse effects. The purpose of this study is to establish the isotretinoin therapy adverse events among human clinical trials and their prevalence.

Vitiligo is described as a dermatological condition characterized by pigmentation disorders in both the skin and mucous membranes. Clinically, this disease is characterized by the presence of well-defined white areas of various shapes and sizes, which are a manifestation of a reduced number of melanocytes. Due to the fact that vitiligo can be a significant cosmetic problem for patients, a number of methods are currently available to help fight for a better skin appearance.

Article Synopsis
  • Psoriasis lesions can recur in the same spots even after treatment because of tissue-resident memory cells (TRM) in the skin that trigger inflammation.
  • This study aimed to examine TRM presence in psoriatic lesions before and after 12 weeks of treatment with various systemic therapies.
  • Results showed that TRM markers decreased over time, particularly with anti-IL-17 therapy, suggesting that systemic drugs may not penetrate the skin effectively, and the behavior of TRM might differ between the dermis and epidermis.

Background: In the course of plaque psoriasis, tissue resident memory cells (TRM) are responsible for the phenomenon of "immune memory" of lesions, i.e., the appearance of recurrences of lesions in the same location, as well as Koebner phenomenon.

By participating in both the recruitment and activation of T lymphocytes, macrophages and neutrophils at the site of psoriatic inflammation, chemokines play an important role in the pathogenesis of psoriasis and, crucially, may be one indicator of the response to the systemic treatment of the disease. As a result of their major involvement in both physiological and pathological processes, both chemokines and their receptors have been identified as possible therapeutic targets. Due to their presence in the inflammatory process, they play a role in the pathogenesis of diseases that often coexist with psoriasis, such as atherosclerosis and psoriatic arthritis.

Hyaluronic acid (HA) is a glycosaminoglycan, a natural component of the extracellular matrix. The identical structure of the molecule in all living organisms is its main advantage, as it translates into the minimal probability of immunogenicity. Therefore, it is the closest to the ideal preparation used as a filler, due to its biocompatibility and stability at the site of implantation.

Caspase-14 is a unique member of the caspase family-a family of molecules participating in apoptosis. However, it does not affect this process but regulates another form of programmed cell death-cornification, which is characteristic of the epidermis. Therefore, it plays a crucial role in the formation of the skin barrier.

Cyclitols are widely available natural sugars which do not exert toxic effects. Their anti-inflammatory and antioxidant properties may be used in the treatment of psoriasis. The aim of this placebo-controlled, double-blind study was to evaluate the clinical effects of D-chiro-inositol (DCI) in mild plaque psoriasis (46 psoriatic patients and 10 healthy volunteers).
