The Prevalence and Risk Factors of Atopic Dermatitis and Clinical Characteristics according to Disease Onset in 19-Year-Old Korean Male Subjects.

Background: The natural course of atopic dermatitis (AD) in infancy, childhood, and adolescence is not yet completely known.

Objective: To investigate the prevalence and risk factors of atopic dermatits among 19-year-old Korean male subjects.

Methods: All 19-year-old Korean males must undergo medical examination for conscription.

Histologic analyses on the response of the skin to 1,927-nm fractional thulium fiber laser treatment.

Background: The histologic responses to varied parameters of 1,927-nm fractional thulium fiber laser treatment have not yet been sufficiently elucidated.

Objective: This study sought to evaluate histologic changes immediately after 1,927-nm fractional thulium fiber laser session at various parameters.

Methods: The dorsal skin of Yucatan mini-pig was treated with 1,927-nm fractional thulium fiber laser at varied parameters, with or without skin drying.

A pilot study for triple combination therapy with a low-fluence 1064 nm Q-switched Nd:YAG laser, hydroquinone cream and oral tranexamic acid for recalcitrant Riehl's Melanosis.

Background: Riehl's melanosis presents as a diffuse gray-brown to black hyperpigmentation around face. The treatment of this disease is challenging and quite limited despite patients' excessive psychological stresses.

Objective: In this prospective pilot study, we evaluated the efficacy and safety for a novel combination therapy based on low-fluence Q-switched 1064 nm Nd:YAG laser, hydroquinone cream and oral tranexamic acid for recalcitrant Riehl's melanosis.

Facial Psoriasis Log-based Area and Severity Index: A valid and reliable severity measurement method detecting improvement of facial psoriasis in clinical practice settings.

Facial psoriasis is often observed in moderate to severe degrees of psoriasis. While we previously demonstrated construct validity of the facial Psoriasis Log-based Area and Severity Index (fPLASI) system for the cross-sectional evaluation of facial psoriasis, its reliability and accuracy to detect clinical improvement has not been confirmed yet. The aim of this study is to analyze whether the fPLASI properly represents the range of improvement for facial psoriasis compared with the existing facial Psoriasis Area and Severity Index (fPASI) after receiving systemic treatments in clinical practice settings.

Avoidance Behavior against Positive Allergens Detected with a Multiple Allergen Simultaneous Test Immunoblot Assay in Patients with Urticaria: Factors Associated with Avoidance Success/Failure.

Background: Avoidance behavior against positive allergens detected by using multiple allergen simultaneous test (MAST)-immunoblot assay in patients with urticaria has been rarely reported.

Objective: We aimed to assess the avoidance behavior of patients with urticaria against positive allergens detected with a MAST.

Methods: One hundred and one urticaria patients who showed positivity to at least one allergen on a MAST completed a questionnaire regarding their test results.
