Article Synopsis
  • Pityriasis rubra pilaris (PRP) is a skin condition marked by inflamed, scaly patches, and its exact causes are still not fully understood.
  • A study involving 102 PRP patients and 800 healthy individuals found significant links between PRP and mutations in the Keratin 32 gene (KRT32), which helps regulate skin inflammation.
  • These findings suggest that KRT32 mutations might contribute to PRP development by leading to increased inflammation, and highlight the potential for KRT32 as a target for new treatments.

Article Synopsis
  • Linear IgA bullous dermatosis (LABD) and dermatitis herpetiformis (DH) are types of autoimmune skin disorders linked to IgA, and this study aimed to explore their causes using serum proteomics.
  • Researchers analyzed 92 biomarkers in serum samples from LABD, DH patients, and healthy controls, discovering elevated levels of certain biomarkers specific to these conditions.
  • The study identified distinct biomarker clusters for LABD and DH, with six specific biomarkers showing potential for better prognosis in DH patients, which could help differentiate these disease subtypes in the future.

Article Synopsis
  • The case study investigates the effectiveness and safety of a Janus kinase (JAK) inhibitor for treating generalized eosinophilic pustular folliculitis (EPF) in a 16-year-old patient who did not respond to traditional treatments.
  • The patient was initially treated with oral tofacitinib, resulting in significant symptom relief, but a relapse occurred when the dosage was reduced.
  • A switch to the more selective JAK1 inhibitor upadacitinib led to complete recovery, suggesting that JAK inhibitors could be a viable option for EPF patients resistant to standard therapies.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematologic malignancy that is highly aggressive with a poor prognosis. There is no standard treatment for BPDCN. Although conventional chemotherapies are usually sensitive in the initial therapy, relapse and drug resistance are inevitable within a short duration.

Verruca vulgaris, caused by the human papillomavirus (HPV), can profoundly impact an individual's quality of life and necessitate therapeutic intervention. The challenges associated with treating verruca vulgaris are particularly noteworthy when they manifest as the Koebner phenomenon (KP). In this report, we present two cases of verruca vulgaris that developed KP following cryotherapy.

Silymarin (SM) exhibits clinical efficacy in treating liver injuries, cirrhosis, and chronic hepatitis. However, its limited water solubility and low bioavailability hinder its therapeutic potential. The primary objective of this study was to compare the in vitro and in vivo characteristics of the four distinct SM solubilization systems, namely SM solid dispersion (SM-SD), SM phospholipid complex (SM-PC), SM sulfobutyl ether-β-cyclodextrin inclusion complex (SM-SBE-β-CDIC) and SM self-microemulsifying drug delivery system (SM-SMEDDS) to provide further insights into their potential for enhancing the solubility and bioavailability of SM.

Dear Editor, Dermatitis herpetiformis (DH) is a chronic, polymorphic, pruritic autoimmune blistering skin disease characterized by subepidermal blisters, neutrophilic microabscesses, and granular IgA deposition within the dermal papillae. DH is classified as a cutaneous manifestation of coeliac disease, a type of gluten-sensitive enteropathy (1). The treatment of DH includes dapsone and a gluten-free diet (GFD).

Chromoblastomycosis is a worldwide chronic subcutaneous infection caused by dematiaceous fungi and clinically characterized by verrucous lesions. Herein, we report a rare case of chromoblastomycosis caused by in a 60-year-old male carpenter with a 40-year history of psoriasis from Shandong in northern China. A fungal infection coexisting with psoriasis presents a management dilemma.

Lung cancer is one of the leading causes of cancer-related mortality, and responds badly to existing treatment. Thus, it is of urgent need to identify novel diagnostic markers and therapeutic targets. Increasing evidences have indicated that long non-coding RNAs (lncRNAs) play an important role in initiation and progression of lung cancer.

Bullous pemphigoid and pemphigus vulgaris, which belong to the group of subepidermal and intraepidermal bullae, respectively, are two potentially devastating blistering skin diseases. We used high-frequency ultrasound (US) in 3 cases of these diseases as prototypes to study the value of high-frequency US in discriminating blister locations. Our findings showed that high-frequency US has a strong correlation with histomorphometric findings because of its high resolution, and we hope that it will be helpful for differentiating blister locations.
