Prolonged use of Personal Protective Equipment, like surgical masks, can cause skin issues such as acne ("maskne") and rosacea flare-ups due to pressure and moisture. While dressings can protect the skin, they often reduce mask effectiveness and lack pharmaceuticals to treat common skin lesions. This study introduces an innovative dual-function gelatin/tannic acid-based hydrogel patch incorporating metronidazole (1% w/w) or salicylic acid (2% w/w) to offer both skin protection and treatment.

Front Immunol

December 2024

Department of Dermatology, State Key Laboratory of Complex Severe and Rare Diseases, National Clinical Research Center for Dermatologic and Immunologic Diseases, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China.

Macrophages, as specialized, long-lasting phagocytic cells of the innate immune system, have garnered increasing attention due to their wide distribution and various functions. The skin, being the largest immune organ in the human body, presents an intriguing landscape for macrophage research, particularly regarding their roles in inflammatory skin diseases and skin tumors. In this review, we compile the latest research on macrophages in conditions such as atopic dermatitis, psoriasis, systemic sclerosis, systemic lupus erythematosus, rosacea, bullous pemphigoid, melanoma and cutaneous T-cell lymphoma.

Impaired Angiogenesis and Th1/Th17 Polarization: A Possible Explanation for the Decreased Incidence of Rosacea in the Aged.

Immun Inflamm Dis

December 2024

Department of Dermatology, The Affiliated Children's Hospital of Xiangya School of Medicine, Central South University (Hunan Children's Hospital), Changsha, China.

Background: Rosacea is a common inflammatory skin disorder characterized by frequent facial flushing, erythema, telangiectasia, and papules, with a higher incidence observed in individuals aged 30-50 years and a tendency to decrease in the elderly. This age-related decline in incidence drew our attention to further explore the relationship between rosacea pathogenesis and aging.

Methods: We analyzed the incidence of rosacea across 8340 individuals without systemic diseases.

Activation of dermal mast cells through the Mas-related G protein-coupled receptor B2 receptor (MrgprB2 in mice and MrgprX2 in humans) is a key component of numerous inflammatory skin diseases, including dermatitis and rosacea. Sensory neurons actively suppress mast cell activation through the regulated release of glutamate, resulting in reduced expression of as well as genes associated with proteins found in mast cell granules. To determine whether exogenous glutamate receptor agonism could suppress mast cell function, we determined that mast cells have relatively selective expression of the glutamate receptor ionotropic, kainate 2 (GluK2).

Purpose: Observational studies have suggested a potential link between emotions and inflammatory dermatoses. However, research on the causal relationship between different types of emotions and inflammatory dermatoses is lacking. This study is aimed to investigate the causal relationship between negative emotions and inflammatory dermatoses through Mendelian randomization (MR) analysis.

Background: Parkinson's disease (PD) is primarily characterized by motor symptoms, but non-motor symptoms, including skin manifestations, are increasingly recognized. These remain underexplored despite their potential impact on quality of life.

Objectives: This study aimed to evaluate the prevalence and clinical features of skin findings in PD patients, with a focus on identifying potential pathogenetic links between dermatological conditions and PD.

Introduction: Rosacea, a chronic inflammatory disease primarily affecting the central area of the face, is a complex condition whose mechanisms are still not fully understood. However, research has indicated a positive correlation between two molecules: hypoxia-inducible factor-1α (HIF-1α) and interleukin-6 (IL-6). The levels of HIF-1α in rosacea patients have yet to be assessed.

Background: In the management of chronic inflammatory skin disease (CISD), continuity of care may influence the achievement of long-term disease control. Barriers to care have been identified in this population, which may leave some patients more vulnerable to loss of follow-up.

Objective: We aim to identify predictors of continuity of care for CISD patients across demographic groups and healthcare practice types in the United States (US).

Topographical variations in the skin barrier and their role in disease pathogenesis.

J Eur Acad Dermatol Venereol

November 2024

Department of Dermatology, MTA Centre of Excellence, Faculty of Medicine, University of Debrecen, Debrecen, Hungary.

The skin barrier can be divided into at least four functional units: chemical, microbial, physical and immunological barriers. The chemical and microbial barriers have previously been shown to exhibit different characteristics in topographically distinct skin regions. There is increasing evidence that the physical and immunological barriers also show marked variability in different areas of the skin.

Introduction: Rosacea is a chronic inflammatory disease presenting with facial flushing, non-transient erythema, papules/pustules, telangiectasia, and phymatous changes. Secondary manifestations, such as itching, burning, or stinging, are often observed in patients with rosacea. The pathogenesis of rosacea is not fully understood, but immune dysfunction, Demodex infection, neurovascular dysregulation, and exposure to ultraviolet radiation represent contributing factors.

Article Synopsis
  • Dermatologists struggle with treating demodicosis due to its recurrence and difficulty in normalizing densities even after improvement.
  • The study evaluated the effectiveness of oral ivermectin (200 µg/kg/week) in improving clinical symptoms and reducing density in 40 demodicosis patients, comparing those with lower and higher densities.
  • Results showed 75% of patients achieved clinical remission, with quicker remission for patients with lower densities (28 days) compared to those with higher densities (56 days).

Article Synopsis
  • Systemic immune system abnormalities may play a role in rosacea development, with studies indicating a higher presence of abnormal bacteria and small intestinal bacterial overgrowth (SIBO) in affected individuals, though inconsistent testing has led to discrepancies in findings.* -
  • This study aimed to accurately assess the prevalence of abnormal bacteria and SIBO in individuals with rosacea while controlling for potential confounding factors, excluding those with gastrointestinal diseases or significant health issues.* -
  • Findings showed that 14.8% tested positive for abnormal bacteria and 33.3% for SIBO, with a notably higher SIBO rate in the rosacea cohort compared to the general population, suggesting a possible link between SIBO and ros

Objectives: Earlier, quickly alternating dual-frequency ultrasound waves (LDM technology) were successfully applied for the treatment of different inflammatory skin conditions such as rosacea and acne. In this retrospective pragmatic two-center clinical study, we applied the triple-frequency LDM (TF-LDM) technology with frequencies of 1/3/10 and 3/10/19 MHz for the treatment of mild-to-severe acne skin to assess the effectivity and sustainability of the treatment outcomes.

Methods: Twenty-two patients with mild-to-severe acne were included in this study: 11 patients were treated with TF-LDM (1/3/10 MHz), and other 11 patients-with TF-LDM (3/10/19 MHz).

November 2024

Department of Dermatology and Venerology, Peking University First Hospital, National Clinical Research Center for Skin and lmmune Diseases, Beijing Key Laboratory of Molecular Diagnosis on Dermatoses, Beijing100034, China.

The neuroimmune mechanism of rosacea has not been fully elucidated, and it is believed that the innate immune system, immune cells, immune regulation, neuroimmune system, signaling pathway abnormalities and microbial dysbiosis are involved in the progress of the neuroimmune mechanism of rosacea. This article reviews the neuroimmune mechanism of rosacea.
