2,3,7,8-Tetrachlorodibenzo--Dioxin Regulates the Expression of Aryl Hydrocarbon Receptor-Related Factors and Cytokines in Peripheral Blood Mononuclear Cells and CD4+ T cells from Patients with Atopic Dermatitis and Psoriasis.

Background: Aryl hydrocarbon receptor (AhR), a ligand-activated transcription factor, is important for xenobiotic metabolism and binds to various endogenous and exogenous ligands in the skin. However, the functional role of AhR in patients with psoriasis (PS) and atopic dermatitis (AD) remains unclear.

Objective: We aimed to determine whether AhR-regulated factors (AhR, CYP1A1, interleukin [IL]-17, IL-22) were affected by AhR ligands (2,3,7,8-tetrachlorodibenzo--dioxin, TCDD) in chronic inflammatory skin diseases such as PS and AD.

Cutaneous Lymphangioma Circumscriptum Occurred Seven Years after Surgery with Soft Tissue Cystic Lymphangioma.

Lymphangiomas are rare benign congenital lymphatic malformations. They can be divided into three groups: cutaneous lymphangioma circumscriptum (CLC), cavernous, and cystic. CLC is the most common type, and rarely occurs with cavernous or cystic lymphangioma under the lesion.

Cowden Disease: Case Report and Review of the Literature.

Cowden's disease is a rare autosomal dominant, multiple hamartoma syndrome with characteristic mucocutaneous lesions. It is associated with abnormalities of the breast, thyroid, and gastrointestinal tract; and is characterized by multiple hamartomas in the gastrointestinal tract and mucocutaneous lesions such as trichilemmomas, oral papillomatosis, facial papules, and acral keratosis. A 21-year-old male patient presented with erythematous facial papules, oral mucosal papillomatosis, and punctate palmoplantar hyperkeratosis indicating a definite case of Cowden's disease.

The Risk of Rosacea According to Chronic Diseases and Medications: A 5-Year Retrospective, Multi-Institutional Case-Control Study.

Background: Rosacea is associated with chronic systemic disease. However, research is lacking in Asian countries.

Objective: To evaluate the association between rosacea and cardiovascular diseases (CVDs) related systemic comorbidities, and the use of antihypertensive and antihyperlipidemic drugs in Korea.

A Histamine-Free Diet Is Helpful for Treatment of Adult Patients with Chronic Spontaneous Urticaria.

Background: In adult patients with chronic urticaria (CU), the prevalence of food allergy is low compared to childhood patients. However, there are many patients who report food-related aggravation of CU, and some of them may have histamine intolerance.

Objective: The aim of this study was to evaluate the role of ingested histamine and to investigate the effect of a histamine-free diet in adult patients with CU.

Immediate Hypersensitivity Reactions Induced by Triamcinolone in a Patient with Atopic Dermatitis.

Corticosteroids are potent anti-inflammatory and anti-allergic agents used in the treatment of various inflammatory diseases, including allergic disease. They are frequently considered the therapy-of-choice for many skin diseases. However, allergic reactions caused by corticosteroids have been reported.

Effect of Different Cooking Methods on Histamine Levels in Selected Foods.

Background: Histamine in food is known to cause food poisoning and allergic reactions. We usually ingest histamine in cooked food, but there are few studies about the influence of cooking method on the histamine level.

Objective: The purpose of this study was to determine the influence of cooking methods on the concentration of histamine in foods.

Clinical Features of Atopic Dermatitis in Adults Are Different according to Onset.

Few studies of atopic dermatitis (AD) in adult patients have evaluated differences in clinical features of AD according to onset age. We aimed to characterize the clinical features of AD in adult patients according to age of onset. Subjects with AD outpatient visiting the Department of Dermatology at Kangnam Sacred Heart Hospital were recruited for this study.

Intense Pulsed Light and Q-Switched 1,064-nm Neodymium-Doped Yttrium Aluminum Garnet Laser Treatment for the Scarring Lesion of Discoid Lupus Erythematosus.

Discoid lupus erythematosus (DLE) is a chronic form of cutaneous lupus that can cause permanent scarring. Treatment of DLE includes protection from sunlight and artificial sources of ultraviolet light, as well as systemic and topical medications. The first-line standard therapies are antimalarials and topical steroids.

Herpes Zoster Duplex Unilateralis: Two Cases and Brief Literature Review.

Cases involving dermatomal herpes zoster in two or more locations are rare, especially in immunocompetent patients. When two noncontiguous dermatomes are involved, if affected unilaterally, it is called herpes zoster duplex unilateralis; if bilaterally, bilateralis. Here, we report two cases of herpes zoster duplex unilateralis.
