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.

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.Publication Metadata only Malignant melanoma arising in congenital melanocytic nevi: clinical and dermoscopic challenges(2017-01-01T00:00:00Z) CENGİZ, FATMA PELİN; EMİROĞLU, NAZAN; BAHALI, ANIL GÜLSEL; SU KÜÇÜK, ÖZLEM SU; ONSUN, NAHİDE; CENGİZ, FATMA PELIN; EMİROĞLU, NAZAN; BAHALI, ANIL GÜLSEL; SU KÜÇÜK, ÖZLEM; ONSUN, NAHIDEPublication Metadata only The Relationship of Psoriasis and Melanocytic Nevi(2016-11-01) Su, Ozlem; Cengiz, FATMA PELİN; Emiroglu, NAZAN; Bahali, ANIL GÜLSEL; OZKAYA, Dilek Biyik; Onsun, NAHİDE; CENGİZ, FATMA PELIN; EMİROĞLU, NAZAN; BAHALI, ANIL GÜLSEL; SU KÜÇÜK, ÖZLEM; ONSUN, NAHIDEBackground: There is limited data about the relationship between psoriasis and melanocytic lesions and melanoma. Immunologic pathways which were implicated in psoriasis induce a reduction in the number of melanocytic nevi. Aims and Objectives: To investigate the number of melanocytic nevi in psoriatic patients compared with controls and its relationship with disease severity and type of treatment. Methods: We performed a prospective study in 100 psoriatic patients and 100 controls. Clinical data were recorded for all participants. Results: As compared with controls, patients had overall fewer nevi congenital nevi. Among psoriatic patients, biologic agents and disease severity did not correlate with the number of nevi. Conclusions: Psoriatic patients have fewer nevi than controls. Frequency of nevi in psoriatic patients is not related to treatment and disease severity.Publication Open Access Which dermatology patients attend to Dermatology Outpatient Clinics during the SARS-CoV-2 outbreak in Turkey and what happened to them?(2020-05-11T04:00:00Z) CENGİZ, Fatma Pelin; EMİROĞLU, Nazan; BAHALI, ANIL GÜLSEL; DİZMAN, DİDEM; TAŞLIDERE, NAZAN; MERT, Ömer; Akarslan, Tahsin Cagdas; Gunes, Begum; KÜÇÜK, Özlem Su; ONSUN, Nahide; CENGİZ, FATMA PELIN; EMİROĞLU, NAZAN; BAHALI, ANIL GÜLSEL; DİZMAN, DİDEM; TAŞLIDERE, NAZAN; GÜNEŞ, BEGÜM; MERT, ÖMER; SU KÜÇÜK, ÖZLEM; ONSUN, NAHIDECoronavirus disease, first emerged in Wuhan, rapidly spread all over the world since December 2019. There are concerns about elective dermatology appointments and its results. Herein, we aimed to find out which type of dermatologic patients attended to dermatology outpatient clinic. The patients visiting the clinics for elective dermatologic diseases between March 11 and 18, 2020, were included in this study. Their age, sex, diagnosis of disease, requirement for emergent intervention, and their medical records about COVID-19 were obtained. There were 390 patients attending to the dermatology outpatient clinic in this period. The most common disease was acne (N: 94, 24%), only 19% of patients need emergent interventions or dose adjustment. There were 40 (10%) patients over the age of 65. After their visits, five patients were diagnosed as COVID-19 in 2weeks. Dermatologic examinations may be a vector for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission since being closed to the patient. Five of our patients were diagnosed as COVID-19 after their elective visit to hospital. Since the asymptomatic course of some young patients, most of our patients were not screened for COVID-19. Our findings support the concerns of elective physician examinations.Publication Metadata only Positive Hepatitis C Serology Due To Intravenous Immunoglobulin: False Positive or True Positive?(2017-05-28T00:00:00Z) CENGİZ, FATMA PELİN; EMİROĞLU, NAZAN; BAHALI, ANIL GÜLSEL; SU KÜÇÜK, ÖZLEM SU; ONSUN, NAHİDE; CENGİZ, FATMA PELIN; EMİROĞLU, NAZAN; BAHALI, ANIL GÜLSEL; SU KÜÇÜK, ÖZLEM; ONSUN, NAHIDEPublication Open Access Acne located on the trunk, whey protein supplementation: Is there any association?(2017-03-05) CENGIZ, FATMA PELİN; Cevirgen, Cemil; EMIROGLU, NAZAN; Gulsel, Bahali; ONSUN, NAHİDE; CENGİZ, FATMA PELIN; EMİROĞLU, NAZAN; BAHALI, ANIL GÜLSEL; ONSUN, NAHIDEWhey protein is a source of protein that was isolated from milk. Whey proteins are composed of higher levels of essential amino acids. The role of diet in acne etiology has been investigated for several years. It was established that milk and milk products can trigger acneiform lesions, and recent evidence supports the role of whey protein supplements in acne. Herein, we report 6 healthy male adolescent patients developing acne located only to the trunk after the consumption of whey protein supplements for faster bodybuilding. This is the first observation which specified the location of acneiform lesions among bodybuilders. In our opinion, a trendy and common health problem is beginning among adolescents in the gyms.
