Patient perspectives on informed consent for medical AI: A web-based experiment.

Objective: Despite the increasing use of AI applications as a clinical decision support tool in healthcare, patients are often unaware of their use in the physician's decision-making process. This study aims to determine whether doctors should disclose the use of AI tools in diagnosis and what kind of information should be provided.

Methods: A survey experiment with 1000 respondents in South Korea was conducted to estimate the patients' perceived importance of information regarding the use of an AI tool in diagnosis in deciding whether to receive the treatment.

Calcipotriol/betamethasone aerosol foam (Enstilum) for the topical treatment of psoriasis vulgaris in routine practice in Korea: A prospective, noninterventional, multicenter study of treatment outcomes and patient satisfaction.

An innovative foam formulation for the fixed-dose combination of calcipotriol and betamethasone dipropionate (Cal/BD) has recently become available for the treatment of psoriasis vulgaris. Observational studies of patients treated with Cal/BD foam in routine practice have been conducted in several Western countries, but there are limited data on outcomes in Asian patients. We performed a prospective, open-label, noncomparative, noninterventional study to investigate treatment outcomes and satisfaction in adult patients receiving Cal/BD foam for psoriasis vulgaris in dermatological centers and outpatient clinics in Korea.

Dental Caries in Adults with Atopic Dermatitis: A Nationwide Cross-Sectional Study in Korea.

Background: Dental caries is the most prevalent chronic infectious oral disease of multifactorial etiology. Increased risk of dental caries development in patients with asthma and allergic rhinitis has been frequently reported. In contrast, only a few studies on dental caries in patients with atopic dermatitis (AD) have been reported.

Validity of Diagnostic Codes for Identification of Psoriasis Patients in Korea.

Background: Recently, the number of nationwide medical researches on psoriasis using the National Health Insurance Service database has been on the rise. However, identification of psoriasis using diagnostic codes alone can lead to misclassification. Accuracy of the diagnostic codes and their concordance with medical records should be validated first to identify psoriasis patients correctly.

A Rare Case of Onychopapilloma Presenting as a Longitudinal Erythronychia.

Onychopapilloma is a rare benign neoplasm of the nail bed and the distal matrix. It is the most common cause of monodactylous localized longitudinal erythronychia. Splinter hemorrhage, onycholysis or distal splitting are usually accompanied due to the subungual keratotic growth located in the corresponding linear streak.

The Value of Type IV Collagen Immunohistochemical Staining in the Differential Diagnosis of Autoimmune Subepidermal Bullous Diseases.

Autoimmune subepidermal bullous diseases (AISBDs) exhibit various clinical presentations, histological appearances, prognoses, and responses to treatment. Many diagnostic techniques, such as direct immunofluorescence (IF), indirect salt-split skin IF, and enzyme-linked immunosorbent assays, are used in the differential diagnoses of AISBDs. However, these techniques require fresh frozen tissue, expensive laboratory equipment, and sophisticated laboratory techniques.

Localized pigmented villonodular synovitis of the proximal tibiofibular joint.

Pigmented villonodular synovitis (PVNS) is a rare disease. It is a benign neoplastic process typically affecting young to middle-aged adults and most commonly involving the knee, hip, and shoulder joints. The symptoms include diffuse pain and swelling with discomfort.

Follicular induction overlying a dermatofibrosarcoma protuberans.

The term "induction" has been used to describe epidermal changes overlying a dermatofibroma (DF). Follicular induction is most often associated with DF, but can be observed in other lesions, including focal mucinosis, nevus sebaceous, seborrheic keratosis, wart, neurofibroma, and scars. Dermatofibrosarcoma protuberans (DFSP) is a malignant fibrohistiocytic tumor that may be difficult to distinguish from DF.

New Onset Guttate Psoriasis Following Pandemic H1N1 Influenza Vaccination.

Since the introduction of H1N1 influenza vaccine in the wake of the 2009 H1N1 pandemic, many serious and non-serious vaccine-related adverse events have been reported. The vaccination could induce pain, erythema, tenderness, and induration on injected areas. These symptoms usually disappear in a few days after the vaccination.

Tinea incognito in Korea and its risk factors: nine-year multicenter survey.

Tinea incognito (TI) is a dermatophytic infection which has lost its typical clinical appearance because of improper use of steroids or calcineurin inhibitors. The incidence of TI is increasing nowadays. We conducted retrospective review on 283 patients with TI from 25 dermatology training hospitals in Korea from 2002-2010 to investigate the demographical, clinical, and mycological characteristics of TI, and to determine the associated risk factors.

[A case of psoriasis induced by infliximab treatment for Crohn's disease].

Infliximab, the monoclonal antibody to tumor necrosis factor, is indicated for refractory luminal and fistulizing Crohn's disease and rheumatoid arthritis. Infliximab treatment has adverse events including infusion reactions, opportunistic infections, and the potential for the event such as reactivation of latent tuberculosis. Cutaneous adverse reactions of TNF-α agents include skin rash, urticaria, pruritus, lupus-like eruption, and injection site reactions.

A novel function of Siglec-9 A391C polymorphism on T cell receptor signaling.

Background: Sialic-acid-binding immunoglobulin-like lectins (Siglecs) are the best-characterized immunoglobulin-type lectins. There is a growing amount of data linking Siglec and autoimmune diseases. The recently identified Siglec-9 inhibits T cell receptor (TCR)-mediated signaling which has been demonstrated by site-directed mutagenesis.

Iatrogenic Kaposi's sarcoma following steroid therapy for nonspecific interstitial pneumonia with HHV-8 genotyping.

We present a case of iatrogenic Kaposi's sarcoma (KS) in a 64-year-old, human immunodeficiency virus (HIV)-negative woman with nonspecific interstitial pneumonia (NSIP) following steroid therapy. She suffered from longstanding exertional dyspnea, and was diagnosed to have NSIP by a thoracoscopic lung biopsy. After 4 months of steroid therapy, multiple purplish nodular or patchy skin lesions developed throughout the entire body.
