    (2019) Aktas, Habibullah; Serifoglu, Cansu
    Aim: The aim of this study was to establish the potential risk of the development of malignancy in the patients with psoriasis. Material and Methods: A retrospective analysis of psoriasis cases between January 2017 to August 2018 attending the dermatology clinic at Karabuk Research and Training Hospital was carried out. Patients with psoriasis were screened whether they have any malignant disease and associated chronic disease including diabetes mellitus and hypertension by using hospital data system. Suspected cases regarding psoriasis or malignant disease were excluded. Findings were compared according to demographic characteristics of the patients. Results: A total of 1551 patients with psoriasis was evaluated in the study time. 30 patients (22 women, 8 men) were found to have malignancy. The most commonly seen malignancy was stomach cancer in women and prostate cancer in men. 2% of patients with psoriasis had cancer. This rate was 2.5% in female patients and 1% in male patients (p <0.005). The mean age of psoriatic patients with cancer was 58.3 years , higher than 41.9 years which is the mean age of all psoriasis patients in the study (p <0.005). The cancer cases were more common in psoriasis patients having diabetes and/or hypertension in comparison with those without diabetes and/or hypertesion (p <0.005). Conclusion: Cancer was found to be more common in female patients with psoriasis particularly in older age group. In addition, diabetes and hypertension have significant contribution to occurrence of the malignancy in patients with psoriasis.

    (2019) Aktas, Habibullah; Unal, Mehmet
    Aim: Alopecia areata is an auto-immune skin disease characterized by non-scarring hair loss. Nail changes are strongly associated with prognosis. In patients with Alopecia areata, the nail examination should not be neglected for an optimal follow-up. Material and Methods: A retrospective study involving 207 patients with Alopecia areata was undertaken in a tertiary hospital between April 2016 and May 2017. Patients whose nail changes were registered in the database were included in the study. Gender, age, disease severity, sites affected, and nail changes of those patients were noted. Results: 114 patients (55%) had nail involvement. The most common nail finding was leukonychia (n = 84). Nail pitting was detected in 29 patients.11 patients had both leukonychia and nail pitting. The mean age of the patients with leukonychia was 23.3, while the mean age of nail pitting patients was 31.7 and the mean age of the patients without nail change was 34.1. Conclusion: Leukonychia is the most common nail change in this study, as a different finding from all previous studies.
