Relationship of psoriatic arthritis with nail and scalp involvement in Turkish psoriasis patients: Multicentered cross-sectional study.

Psoriasis is a common multisystem inflammatory disease, and arthritis is an essential component of the disorder, requiring early diagnosis and prompt treatment for successful management. In this study, we aimed to investigate the relationship between nail and scalp involvement and other covariates with psoriatic arthritis (PsA). This cross-sectional study, conducted from June 2021 through December 2021, included 763 patients from 11 different centers in Turkey.

Evaluation of the Factors Influencing Mortality in Patients with Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis: A Multicenter Study of 166 Patients.

Introduction: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are life-threatening acute mucocutaneous disorders usually triggered by drugs. In this study, we aimed to evaluate the factors affecting mortality in patients with SJS-TEN.

Methods: Our study is a retrospective cohort study, analyzing data collected from a total of 12 tertiary care centers between April 2012 and April 2022.

Omalizumab versus cyclosporin-A for the treatment of chronic spontaneous urticaria: can we define better-responding endotypes?

Background: Chronic Spontaneous Urticaria (CSU) is characterized by recurrent wheals and/or angioedema for longer than 6-weeks. Guidelines recommend Omalizumab (Oma) as first-line and Cyclosporine-A (Cs-A) as second-line treatment in antihistamine resistant CSU. This step-wise algorithm might be time-consuming and costly.

Birt-Hogg-Dubé Syndrome: Diagnostic Journey of Three Cases from Skin to Gene.

Birt-Hogg-Dube syndrome (BHDS) is a rare disorder characterized by the triad of cutaneous lesions, renal tumors, lung cysts and inactivation of the gene (). Here, we present three female patients diagnosed with BHDS. First case a 55-year-old female had flesh moles histopathology compatible with angiofibroma, multiple cysts in the lung and kidneys, gene mutations ('c.

Patch Test Results to European Baseline Series in Turkey: A Prospective and Multicenter Study.

Background: Patch testing with the European Baseline Series (EBS) is an essential diagnostic tool for the assessment of allergic contact dermatitis.

Objective: The aims of the study were to describe the most common contact allergens identified with patch testing in Turkey and to establish the distribution of contact allergens among different regions in Turkey.

Patients And Methods: Twelve centers consisting of tertiary health care institutions were included in the study.

Epidemiology of Pemphigus in Turkey: One-year Prospective Study of 220 Cases.

Pemphigus is a group of rare and life-threatening autoimmune blistering diseases of the skin and mucous membranes. Although they occur worldwide, their incidence shows wide geographical variation, and prospective data on the epidemiology of pemphigus are very limited. Objective of this work is to evaluate the incidence and epidemiological and clinical features of patients with pemphigus in Turkey.

The efficacy of narrowband UVB treatment in pediatric vitiligo: a retrospective analysis of 26 cases.

Background/aim: Narrowband UVB (Nb UVB) treatment is commonly used for the management of psoriasis and atopic dermatitis, and is less often used for vitiligo in children. The aim of this study was to evaluate the efficacy and short-term safety of Nb UVB phototherapy in children diagnosed with vitiligo retrospectively.

Materials And Methods: A total of 26 patients younger than 18 years with the diagnosis of vitiligo and managed with Nb UVB phototherapy as documented in archive records were evaluated.

Multiple warty dyskeratomas: case report.

Warty dyskeratoma is a rare tumor that presents mainly as an isolated papule or nodule on the scalp, face or neck in the adults. Warty dyskeratoma frequently arises as a single lesion with a central keratotic plug on the skin of middle-aged or elderly people. Multiple warty dyskeratomas are very rare cutaneous lesions which are mostly seen on the scalp.

A case of mycosis fungoides-like lesions developing after levetiracetam therapy.

Levetiracetam is a relatively new antiepileptic drug that has previously not been associated with severe dermatological side effects. We report the case of a 31-year-old male treated with levetiracetam for seizures who subsequently developed a mycosis fungoides-like drug reaction that resolved upon dosage reduction.

Generalized Sweet syndrome lesions associated with Behçet disease: a true association or simply co-morbidity?

Sweet syndrome or acute febrile neutrophilic dermatosis is a condition characterized by painful erythematous papules, nodules, and plaques, which demonstrate mature neutrophilic infiltration of the upper dermis histopathologically, and is usually associated with systemic symptoms such as fever and neutrophilia. Generalized Sweet syndrome lesions are usually noted in association with malignancies. Sweet syndrome lesions are rarely seen in patients with Behçet disease and, if present, are usually fewer in number.

Efficacy and safety of long-term mycophenolate sodium therapy in pemphigus vulgaris.

Background: Pemphigus is a chronic immunobullous disease, characterized by formation of blisters and erosions in skin and/or mucous membranes. This severe disease requires systemic immunosuppressive therapy. However, some patients are refractory, and long-term use of immunosuppressive agents can cause serious side-effects.

Miliary osteoma cutis of the face: treatment with the needle microincision-extirpation method.

Multiple miliary osteoma cutis of the face represents primary extra-skeletal bone formation that arises within the skin of the face. Multiple miliary osteoma cutis of the face is a rare complication of chronic inflammatory acne vulgaris and has invasive and non-invasive treatment alternatives different from acne vulgaris. Invasive techniques should be simple, easy, and inexpensive, with minimal risk of scarring and pigmentation.

Parry-Romberg syndrome associated with borreliosis: could photochemotherapy halt the progression of the disease?

Parry-Romberg syndrome (PRS) or progressive hemifacial atrophy is a rare entity characterized by unilateral atrophy of the skin, subcutaneous tissue and sometimes bone and cartilage. Although this syndrome has overlapping features of scleroderma 'en coup de sabre', it shows little or no sclerosis and may affect the entire distribution of the trigeminal nerve including the eye and tongue. As the pathogenesis is unknown, no effective therapy exists.

A case of epidermodysplasia verruciformis associated with squamous cell carcinoma and Bowen's disease: a therapeutic challenge.

Epidermodysplasia verruciformis (EV) is a very rare and chronic disease characterized by a susceptibility to cutaneous infections by a group of phylogenetically related human papillomavirus (HPV) types. We present here a 52-year-old man previously diagnosed and treated as squamous cell carcinoma but also found to have epidermodysplasia verruciformis lesions in association with Bowen's disease. The patient was effectively treated with a combination of interferon therapy (6 million units, twice a week) and topical imiquimod for Bowen's disease (five times a week).

Lack of correlation between Helicobacter pylori infection and autologous serum skin test in chronic idiopathic urticaria.

Background: There are controversial reports about the direct role of Helicobacterpylori infection in chronic idiopathic urticaria. The indirect role of H. pylori infection in the induction of pathogenetic antibodies is not fully elucidated either.

Localized unilateral hyperhidrosis and neurofibromatosis type 1: case report of a new association.

Localized unilateral hyperhidrosis (LUH) is an uncommon but well-defined special form of localized hyperhidrosis with diverse causes. It often occurs within a sharply demarcated area on the face or upper extremities. Here, we report a case of LUH in a 16-year-old male with neurofibromatosis type 1 (NF1) and review related data in the literature.
