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.

Thyroid abnormalities in paediatric patients with vitiligo: retrospective study.

Introduction: The association between vitiligo and thyroid disease is not fully investigated especially in paediatric patients.

Aim: To determine the incidence of vitiligo and thyroid disorders in children. This is the first report from middle Anatolia and the second report from Turkey.

A novel approach in psoriasis: first usage of known protein oxidation markers to prove oxidative stress.

Oxidative stress may play a pivotal role in the pathogenesis of psoriasis, an inflammatory/hyperproliferative skin disease characterized by the cutaneous accumulation of neutrophils releasing reactive oxygen species, as revealed in a number of studies. This study was performed to demonstrate the presence of oxidative stress in psoriasis, as measured by protein oxidation markers. Twenty-nine psoriasis patients were selected based on disease severity assessment using body surface area as well as the psoriasis area severity index (PASI), and were grouped as mild (PASI ≤ 10) and moderate-to-severe (PASI > 10).

Association between isolated female acne and insulin resistance: a prospective study.

Background: Acne is one of the manifestations of the polycystic ovary syndrome (PCOS). Nowadays hyperinsulinemia and insulin resistance are well-known characteristics of PCOS. The aim of this study was to investigate the relation between isolated female acne and insulin resistance and to determine the effect of hyperandrogenemia in this possible relationship.

Evaluation of etiological factors in patients with chronic urticaria.

In the last few decades, increasing understanding of the pathomechanisms involved in chronic urticaria has highlighted the heterogeneity of different subtypes, and chronic urticaria is now classified as chronic spontaneous urticaria and inducible urticaria. Although many factors are thought to be involved in chronic urticaria, the etiology is yet to be clarified. The purpose of this study was to investigate etiological factors in patients with chronic urticaria.

Scabies mimicking mastocytosis in two infants.

Scabies is a common parasitic human infection in infants and children. However, diagnostic pitfalls are frequent in infants, in whom the clinical presentation is usually atypical and different from that in adults. In nodular scabies, lesions may be clinically or histologically misdiagnosed as Langerhans cell histiocytosis, insect bite reaction, non-Langerhans cell histiocytosis, lymphoma, or urticaria pigmentosa.

Environmental risk factors in pediatric psoriasis: a multicenter case-control study.

To analyze the effect of possible risk factors, including breastfeeding, on the development of childhood-onset psoriasis, a multicenter case-control study with prospective collection of data was performed. Using a standard questionnaire, personal and specific variables including family history of psoriasis, maternal and environmental tobacco smoke exposure, body mass index (BMI), exclusive and partial breastfeeding for at least 3 and 12 months, cow's milk intake before 1 year, birth delivery method, and stressful life events were collected during 2009 from 537 patients with psoriasis and 511 controls younger than 18. Overall, patients more frequently reported exposure to environmental tobacco smoke at home and stressful life events in the year preceding the diagnosis than controls.

Baboon syndrome and segmental vitiligo coexistence.

The baboon syndrome is a form of systemic contact dermatitis with skin eruptions in the area of the buttocks and major flexures. Inhalation of mercury vapor causes this rare but distinctive eruption. Broken thermometers are the usual sources of exposure.

Prevalence of cutaneous findings in hospitalized neonates: a prospective observational study.

Objective: To determine the frequency of physiologic and pathologic skin findings in the newborns hospitalized in our Newborn Unit.

Methods: All of newborn infants hospitalized in the Newborn Unit of Erciyes University Medical School Hospital in Central Anatolia, Turkey from February 1 to November 30, 2003, were included prospectively in the study. A questionnaire regarding maternal gestational history, maternal and family history was administered to the parents of each child.

Patients with vulval pruritus: patch test results.

Background: Persistent vulval pruritus is a frequent problem and patients may not show signs of a primary vulval dermatosis. Allergic contact sensitivity is an important factor in such patients but may also occur as a secondary event in women with vulval dermatoses.

Objectives: We aim to describe women with vulval pruritus who were evaluated for vulval dermatoses.

Demographic and clinical properties of juvenile-onset Behçet's disease: A controlled multicenter study.

Background: Behçet's disease (BD) is a multisystemic inflammatory disorder of unknown origin. The disease usually occurs between the second and the fourth decades, whereas it is uncommon in children.

Objective: In this multicenter study, we aimed to describe the demographic and clinical features along with severity in juvenile- versus adult-onset BD.

Investigation of the skin characteristics in patients with severe GH deficiency and the effects of 6 months of GH replacement therapy: a randomized placebo controlled study.

Objective: The presence of GH receptor in human skin and its appendages suggests a direct effect of GH on skin characteristics. The skin is usually thin and dry in patients with GH deficiency (GHD). Sheehan's syndrome classically refers to postpartum hypopituitarism and GH is one of the earliest pituitary hormones lost.

Rosacea fulminans in pregnancy: case report and review of the literature.

Rosacea fulminans is a rare disease of unknown cause which occurs exclusively in women years after adolescence. Although the etiology is unknown, immunologic, hormonal, and vascular factors have been suggested. When rosacea fulminans occurs during pregnancy and in women taking oral contraceptive pills, hormonal factors may be a trigger.

Cutaneous lupoid leishmaniasis: a case report.

Cutaneous leishmaniasis is a disease transmitted by the sandfly. During the course of the disease, all classical stages of the development of leishmaniasis from small erythematous papules to nodules to ulcerative lesions can be seen. We report a case of lupoid leishmaniasis (LL) treated with daily intramuscular injections of meglumine antimoniate for 20 days with marked improvement of clinical features.

Micronucleus evaluation in mitogen-stimulated lymphocytes of narrow-band (311 nm TL01) UVB-treated patients.

Background: Narrow-band UVB (311 nm) lamps (TL01) are being increasingly used for phototherapy of psoriasis and other dermatoses, for their excellent effect compared with broad-band UVB sources and photochemotherapy. It is acknowledged that the TL01 lamp is probably two to three times more carcinogenic per minimum erythema dose than broad-band UVB, but the cumulative dose is considerably less than broadband UVB sources. Micronucleus (MN) test is used to detect both clastogenic (breaking) and aneugenic (abnormal segregation) effect of physical/chemical agents on chromosomes.

Clinical evaluation of roxithromycin: a double-blind, placebo-controlled and crossover trial in patients with acne vulgaris.

We clinically evaluated roxithromycin (ROM) in a double blind, placebo-controlled, and crossover trial in patients with inflammatory acne. Patients with inflammatory acne who were attending our outpatient clinic for treatment and who had not received topical or systemic treatment for the previous month were enrolled in this study. Patients were randomly separated into two groups.

Antioxidant potential of propylthiouracil in patients with psoriasis.

Objective: There is growing evidence supporting the reactive oxygen species (ROS) in the pathogenesis of psoriasis. Propylthiouracil(PTU), an antithyroid drug, has been shown to have beneficial effects on psoriasis. The aim of this study was to investigate both disturbances in oxidant/antioxidant system in psoriasis and whether PTU, shown to have immunomodulatory effects and antioxidant potential, has effects on oxidant/antioxidant system and clinical improvement in psoriatics.
