Pruritus is the most commonly occurring subjective symptom of dermatological disease. Published data on both prevalence and intensity of pruritus in psoriasis is limited. Objective: In this study we aimed to investigate the prevalence of pruritus and its relation with psoriasis area severity index, body mass index and presence of systemic disease in patients with psoriasis. Methods: We analyzed data of psoriatic patients diagnosed in our psoriasis outpatient clinic between March 2013 and June 2014 collected retrospectively from PSR-TR registration system. Results: In total, 880 patients were analyzed. Pruritus was more prominent in female patients. This difference was statistically significant. No significant associations were found between age of patients, clinical type of disease and pruritus. The itching was more common in patients with higher body mass index. Presence of pruritus was correlated significantly with severity of psoriasis. Five hundred and sixty of 880 patients had no systemic disease. The presence of pruritus was not related with presence of systemic disease. Existence of systemic disease with psoriasis has minimal effect on pruritus. Study Limitations: We did not evaluate intensity of pruritus. Conclusions: Pruritus is not mentioned within the classical symptoms of psoriasis. Pruritus in psoriasis is a very unpleasant symptom with great potential to impair patient’s quality of life and may exacerbate psoriasis as a Koebner phenomenon.

Background: Congenital melanocytic nevi (CMN) are present at birth. It is well known that the presence of large-sized congenital nevus in early life could predict a major risk of developing melanoma. Objective: To investigate the clinical and dermoscopic features of the CMN, to search for and highlight any differences between small-sized, medium-sized, large-sized CMN. Methods: A nonrandomized observational study was performed. A total of 108 melanocytic nevi were analysed by clinical and dermoscopic examination. Results: Of the subjects, 57.4% were aged less than 16 years, 42.6% were aged 16 and more. Of the nevi, 26 had reticular pattern (24.1%), 35 had globular pattern (32.4%), 13 had reticular-globular pattern (12.0%), 16 had homogeneous pattern (14.8%), 6 had reticular-homogeneous pattern (5.6%), 2 had globular-homogeneous pattern (1.9%), 7 had cobblestone pattern (6.5%), 3 had reticular patchy pattern (2.8%). Atypical dots and globules, focal hypopigmentation and perifollicular hypopigmentation are the most common dermoscopic features of CMN. The rarest dermoscopic feature is the blue-whitish veil. Conclusion: Most of the dermoscopic features related with dysplastic nevi up to the present, such as atypical dots and globules, focal hypopigmentation, perifollicular hypopigmentation were observed in CMN, in our study. Congenital nevus and dysplastic nevi may share the same dermoscopic features, therefore it is important to know it is found at birth or not.

ackground:: Pigmented purpuric dermatosis is a chronic skin disorder of unknown aetiology characterised by symmetrical petechial and pigmented macules, often confined to the lower limbs. The aetiology of pigmented purpuric dermatosis is unknown. Dermatoscopy is a non-invasive diagnostic technique that allows the visualisation of morphological features invisible to the naked eye; it combines a method that renders the corneal layer of the skin translucent with an optical system that magnifies the image projected onto the retina. Objectives:: The aim of this study is to investigate the dermatoscopic findings of pigmented purpuric dermatosis. Methods:: This study enrolled patients diagnosed histopathologically with pigmented purpuric dermatosis who had dermatoscopic records. We reviewed the dermatoscopic images of PPD patients who attended the outpatient clinic in the Istanbul Dermatovenereology Department at the Bezmialem Vakıf University Medical Faculty. Results:: Dermatoscopy showed: coppery-red pigmentation (97%, n = 31) in the background, a brown network (34%, n = 11), linear vessels (22%, n = 7), round to oval red dots, globules, and patches (69%, n = 22; 75%, n = 24; 34%, n = 11; respectively), brown globules (26%, n = 8) and dots (53%, n = 17), linear brown lines (22%, n = 7), and follicular openings (13%, n = 4). Conclusion:: To our knowledge, this is the first study to report the dermatoscopy of pigmented purpuric dermatosis. In our opinion, dermatoscopy can be useful in the diagnosis of pigmented purpuric dermatosis.

Abstract: Background: Localized scleroderma is a chronic inflammatory skin disease characterized by sclerosis of the dermis and subcutaneous tissue. Platelets play an important role in inflammation. Following activation, platelets rapidly release numerous mediators and cytokines, which contribute to inflammation. Objectives: To evaluate whether there was any relation between localized scleroderma and platelet parameters. Methods: Forty-one patients with localized scleroderma were enrolled in the study. The control group consisted of 30 healthy subjects. Results: The mean platelet volume level in the patient group was 9.9 ± 1.3 fl and in the control group was 7.6 ± 1.1 fl. This difference was statistically significant (p< 0.001). The plateletcrit values are minimally higher in the patient group as compared to the control group. It was statistically significant (p<0.001). There was no significant difference in the platelet counts between the two groups (p= 0.560) In the patient group, there was no significant relation between the mean platelet volume levels and clinical signs of disease (p=0.09). However, plateletcrit values are higher in generalized than localized forms of disease (p=0.01). Study Limitations: The limited number of patients and the retrospective nature of the study were our limitations. Conclusions: This study suggests that platelets might play a role in the pathogenesis of scleroderma. Platelet parameters may be used as markers for evaluating disease severity and inflammatory processes. Thus, there is a need for more detailed and prospective studies.

Introduction: Atopic dermatitis (AD) is a chronic relapsing inflammatory skin disorder. Vitamin D is a liposoluble vitamin synthesized mainly in the skin. Vitamin D has several effects on the skin. Aim: To assess the serum level of vitamin D in children with AD and determine its relation to AD severity. Material and methods: Sixty patients with AD were enrolled in the study. We evaluated disease severity using the SCORing Atopic Dermatitis (SCORAD) index. The control group consisted of 37 healthy subjects. Results: The mean serum concentration of 25(OH)D3 in patients with AD was not statistically different from control subjects (p = 0.065). The vitamin D level was significantly lower in moderate and severe AD compared with mild AD, and this difference was statistically significant (p = 0.001 and p = 0.004). Vitamin D showed a negative correlation with serum total IgE levels (p = 0.007). There was no significant correlation between total IgE levels and SCORAD scores (p = 0.089). Conclusions: This study suggests that a low serum vitamin D level is inversely associated with severity of AD in children. Vitamin D has not been included in the routine treatment of AD because of the conflicting results of various studies. Thus, there is a need for more detailed and prospective studies.

(2016-01-01) OZKAYA, Dilek Biyik; Onsun, NAHİDE; Su, Ozlem; Bahali, ANIL GÜLSEL; Dizman, DİDEM; Rezvani, AYLİN; Uysal, Omer; ONSUN, NAHIDE; SU KÜÇÜK, ÖZLEM; BAHALI, ANIL GÜLSEL; DİZMAN, DİDEM; REZVANİ, AYLİN; UYSAL, ÖMER
Introduction: Psoriasis is a chronic, immune-mediated inflammatory disease predominantly affecting the skin, with a complex aetiology. Recently it has been suggested that the chronic inflammation of psoriasis may cause metabolic and vascular disorders. The relationship between obesity and psoriatic arthritis (PsA) is not clear, and there are insufficient prospective studies addressing this subject. Aim: To investigate the relationship between psoriatic arthritis, severity of psoriasis and obesity in the Turkish population. Material and methods: Patient data from psoriasis outpatient clinics from February 2007 to July 2013 were reviewed retrospectively using the Psoriasis-Turkey (PSR-TR) registration system. Patients' age, onset age, body mass index (BMI), waist circumference, psoriasis area and severity index (PASI), and arthritis information were reviewed. In the outpatient clinics, patients who had joint pain consulted rheumatology clinics. The CASPAR criteria were used for the diagnosis of arthritis. Results: A total of 443 males and 495 females enrolled in this study. The mean age of females was 43.9 years (18-93 years) and the mean age of males was 44.6 years (18-89 years). A total of 231 (25%) patients had psoriatic arthritis. Investigation of the relationship between PASI, BMI, waist circumference (WC) and arthritis revealed a statistically significant relationship between each variable. Conclusions: In this study we observed a relationship between PsA and high BMI, high WC and high PASI. Psoriatic arthritis is a chronic inflammatory disorder and a chronic inflammatory state induced by adiposity may lead to PsA.

Purpose. Psoriasis vulgaris is one of the most common skin disorders. Patients with psoriasis carry an excessive risk of atrial fibrillation (AF). The differences between the maximum (Pmax) and the minimum (Pmin) P-wave duration on ECG are defined as P-wave dispersion (PWD). Prolongation of PWD is an independent risk factor for the development of AF. The aim of this the study was to investigate P-wave duration and PWD in patients with psoriasis. Methods. Sixty-one adult patients with psoriasis vulgaris (group 1) and 58 age and sex-matched healthy individuals (group 2) were included in this study. ECG recordings were obtained, and the P-wave variables were calculated. Results were reported as mean ± standard deviation and percentages. Continuous variables were analysed using Student’s t test. A value of P < 0.05 was considered statistically significant. Results. Pmax and PWD were significantly higher in group 1 than in group 2 (108.8 ± 21.3 ms versus 93.3 ± 13.0 ms, P < 0.001; 67.4 ± 22.9 ms versus 45.0 ± 19.6 ms, P < 0.001, respectively). Also, Pmin was significantly lower in group 1 (41.3 ± 12.3 ms versus 48.3 ± 14.3 ms, P = 0.04). The psoriasis disease activity score and hsCRP correlated with PWD (P < 0.01). Conclusions. Atrial conduction of sinus impulses was impaired in patients with psoriasis vulgaris. It was more prominent in patients with severe disease. Physicians caring for patients with psoriasis vulgaris should screen them for AF development.

(2014-09-01) OZKAYA, Dilek Biyik; Onsun, NAHİDE; TOPUKCU, Bugce; Su, Ozlem; Dizman, DİDEM; Uysal, Omer; ONSUN, NAHIDE; SU KÜÇÜK, ÖZLEM; DİZMAN, DİDEM; UYSAL, ÖMER
Background and Design: Psoriasis is a chronic immune-mediated inflammatory disease affecting 1-3% of the general population. Recently, it has been suggested that chronic inflammation in psoriasis may cause metabolic and vascular disorders. Most of recent studies focused on the comorbidities and the mechanisms of comorbidities associated with psoriasis. Obesity may lead to cardiovascular disorders, diyabetes mellitus, hypertension, malignancies, musculoskeleteal system diseases, impaired quality of life, and death. In this study, we aimed to investigate the prevalence of obesity in patients with psoriasis and the relationship between the disease severity and body mass index (BMI) in Turkish psoriasis population.

(2011-09-01) Su, Ozlem; ULUSAL, Hande Arda; OZKAYA, Dilek Biyik; Onsun, NAHİDE; SU KÜÇÜK, ÖZLEM; ONSUN, NAHIDE
Linear nevus sebaceous syndrome (LNSS) is a phakomatosis, associated with a variety of developmental abnormalities of ocular, nervous, skeletal, cardiovascular and urogenital systems. In LNSS, choristomas and colobomas are frequently seen signs, but complex choristomas are rare. We describe a case of a 3-year-old boy with a yellow alopecic plaque on his scalp, face and neck as well as a mass in the episcleral region since birth. He also had epileptic seizures since one year old. Histopathological examination of episcleral specimen revealed choristoma. Magnetic resonance imaging of the brain identified hemimegalencephaly, hemicerebral atrophy, and lateral ventricular enlargement (Turkderm 2011; 45: 155-7)
