Background/Objectives: Chronic spontaneous urticaria (CSU) is a common skin disorder which represents a challenge both for the patients and physicians. Guidelines and treatment algorithms have been created to help physicians to ease management. Our aim was to determine Turkish dermatologists' approach to CSU with regard to treatment, search for causative factors and use of instruments to assess the quality of life and severity of the disease. Methods: This was a cross-sectional methodological study which was performed by delivery of a questionnaire including ten questions about the management of CSU. Results: Analyses of 314 questionnaires revealed that the most common first-line treatments were non-sedating antihistamines in standard doses (65.6\%), while second-line treatment was updosing antihistamines (59.9\%) followed by addition of sedative-antihistamines (26.4\%) and systemic steroids (19.1\%). Third-line treatment option was omalizumab in 35\% followed by systemic steroids. Twenty-two percent of the dermatologists referred the patients to a center experienced in urticaria. Most of them were performing laboratory testing for underlying causes including thyroid function tests, C-reactive protein, thyroid auto-antibodies, stool analyses, infection markers. Urticaria activity score and chronic urticaria quality of life questionnaire were used by 30 and 13\%, respectively, while 56\% were using none of the instruments. Conclusion: Our study showed that the therapeutic management of Turkish dermatologists was parallel to the European Urticaria Guidelines. The high utility of omalizumab as a third line regimen improved patient care. Nevertheless there is a need for centers experienced in urticaria to refer anti-histamineresistant patients where third-line treatment options can not be implemented.

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.

Acrokeratosis Verruciformis is a rare autosomal dominant genodermatosis. Typically, the lesions are small, verrucous, flat papules on the dorsal aspects of the hands and feet, elbows and knees. Herein, we report a sporodic case of acrokeratosis verruciformis, succesfully treated with acitretin, and review of the literatures. (Turkderm 2009; 43: 35-7)

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.

Background There are a few case reports in literature that isotretinoin treatment may alter sleep architecture. Also studies in mice suggest a role of retinoids in the contribution of delta oscillations to the sleep electroencephalography. Objectives The aim of this study was to investigate the effect of isotretinoin treatment on sleep architecture using polysomnography (PSG). Patients and methods Twelve severe acne vulgaris patients without any psychiatric and sleep disorders were treated with 0.5 mg/kg of isotretinoin. Clinician-administered acne questionnaire, psychiatric examination, Epworth sleepiness scale and PSG recordings were performed after the first month of treatment. Results Sleep efficiency was increased from 83.5% (62.889.0%, quartiles) to 89.5% (81.593.5%, quartiles; P = 0.036) and sleep latency decreased from 18.0 min (11.136.3, quartiles) to 15.5 min (9.319.0, quartiles; P = 0.023) following 1-month isotretinoin treatment. There were no significant changes in other sleep parameters of PSG and scores of Epworth sleepiness scale. Conclusions This study suggests that isotretinoin treatment slightly improves night-time sleep without any effects on sleep stages and daytime sleepiness.

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. The odds ratios (OR) for smoking and stressful life events were 2.90 (95% confidence interval [CI] = 2.27-3.78) and 2.94(95% CI = 2.28-3.79), respectively. In addition, children with psoriasis were more likely to have a higher BMI (>26) than controls (OR = 2.52; 95% CI = 1.42-4.49). High BMI, environmental tobacco smoke exposure at home, and stressful life events may influence the development of pediatric psoriasis.

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. We hereby present a 14-year-old boy diagnosed with baboon syndrome coexistence with vitiligo, due to broken thermometers. In our case, it was interesting that erythematous eruptions were more evident on the vitiliginous side of the trunk. To our knowledge, there have been no reports in the literature of baboon syndrome and vitiligo coexistence.
