Methods: In this cross-sectional study, 979 patients with BS were included from16 centres in Turkey, Jordan, Brazil and the United Kingdom. In the CART algorithm, activities of oral ulcer (active vs.

Epidemiological characteristics of different types of adult acne in Turkey: a prospective, controlled, multicenter study.

Introduction: Acne occurring in adults over the age of 25 years is known as acne tarda or adult acne. Three types of adult acne are recognized: persistent, late-onset, and recurrent acne. Most studies do not compare the characteristics between the three variants.

Clinical trait-specific genetic analysis in Behçet's disease identifies novel loci associated with ocular and neurological involvement.

Behçet's disease is a complex inflammatory vasculitis with a broad spectrum of clinical manifestations. The purpose of this study was to investigate the genetics underlying specific clinical features of Behçet's disease. A total of 436 patients with Behçet's disease from Turkey were studied.

Internalized Stigma in Hidradenitis Suppurativa: A Multicenter Cross-Sectional Study.

Background: Hidradenitis suppurativa (HS) causes significant physical, social, and psychological burdens. Internalized stigma, acceptance of negative attitudes and stereotypes of society regarding a person's illness, has not been studied previously in HS.

Objectives: The objective of this study was to investigate the internalized stigma state of HS patients and identify the factors affecting it.

Patient Use of Complementary and Alternative Medicine for Psoriasis Vulgaris and Factors Believed to Trigger the Disease: a Multicenter Cross-Sectional Study With 1621 Patients.

Introduction: Due to the chronic recurrent nature of psoriasis vulgaris (PV) and lack of definitive treatment for the disease, patients often resort to alternative treatments. Physicians seem to have low awareness of this issue.

Objectives: To elicit the perceptions of 1,621 PV patients on complementary and alternative medicine (CAM) and examine factors reported to worsen PV.

Mucocutaneous manifestations of Behçet's disease: Pathogenesis and management from perspectives of vasculitis.

Behçet's disease (BD) is a systemic inflammatory disorder characterized by vasculitis affecting blood vessels of any caliber or type. It can present with a wide spectrum of vasculitic lesions, including erythema nodosum-like lesions and retinal vasculitis, and may also lead to larger vessel diseases, such as aortic aneurysm and deep vein thrombosis. The full etiology of BD remains unclear, but it is considered a polygenetic disease with multiple genetic risk factors that promote immune dysregulation and thrombophilia.

Use of Complementary and Alternative Medicine among Patients with Acne Vulgaris and Factors Perceived to Trigger the Disease: A Multicentre Cross-Sectional Study with 1571 Patients.

Background: Acne vulgaris (AV) is among the common skin diseases for which patients refer to complementary and alternative medicine (CAM).

Standard Patch Test Results and Clinical Relevance: A Cross-Sectional Study of 10-year Retrospective Experience.

Background: Allergic contact dermatitis (ACD) is a type IV hypersensitivity reaction, and The European Standard Series (ESS) Patch Test (PT) is widely used in determining the possible responsible allergens causing ACD.
