    Lichen planopilaris: Demographic, clinical and histopathological characteristics and treatment outcomes of 25 cases
    (2015) Ozcan, Deren; Seckin, Deniz; Gulec, A.Tulin; Ozen, Ozlem; 0000-0002-7450-6886; 0000-0002-9082-1317; AAQ-6649-2021; AAK-4468-2021
    Background and Design: Lichen planopilaris (LPP) is a type of cicatricial alopecia characterized by autoreactive lymphocytic destruction of the hair follicle. We aimed to evaluate the demographic, clinical and histopathological features, and treatment outcomes of patients with LPP. Materials and Methods: Medical reports of 25 patients, who have been diagnosed with LPP according to the clinical and histopathological findings between January 2006 and June 2012, were retrospectively reviewed. The transverse and vertical sections of scalp biopsy specimens were re-evaluated by a pathologist, and the findings were noted. Results: Of the 25 patients, 18 were female and 7 were male, the mean age was 49.8 +/- 12.4 years. Eighteen patients had been diagnosed with classic LPP and 7 patients with frontal fibrosing alopecia (FFA). The alopecia has begun in postmenopausal period in 5 patients with FFA. Alopecia was associated with pruritus, pain and/or burning in 19 patients. Extra-scalp involvement was observed in 11 patients. The most common clinical findings were follicular hyperkeratosis (92%), perifollicular erythema (48%), perifollicular lichenoid papules, and positive hair-pull test (44%). Dermatoscopic examination was performed in 14 patients, and most commonly, absence of follicular openings (100%), perifollicular scales (92.9%) and perifollicular erythema (50%) were noted. The most common diagnostic histopathological findings were follicular vacuolar and lichenoid degeneration (88%) and vacuolar and lichenoid interface changes (56%). Twenty-three patients who were started on treatment received topical, intramuscular and intralesional corticosteroids, topical minoxidil, oral tetracycline, cyclosporine A, and hydroxychloroquine either alone or in combination. Progression of alopecia was prevented and the symptoms and/or signs were reduced in 12 (75%) of 16 patients whose follow-up data were available. Conclusion: LPP can be diagnosed accurately through a detailed clinical examination, dermatoscopy and histopathological examination. The symptoms and/or signs can be reduced and progression of the disease can be prevented with treatment.

    Role of Latex Hypersensitivity in Patients with Chronic Urticaria
    (2016) Durdu, Murat; Seckin, Deniz; 0000-0003-1247-3932; H-9068-2019
    Objectives: In this study, we aimed to determine the frequency of latex hypersensitivity in patients with chronic urticaria and to investigate the effect of latex-cross reacting food on the clinical course of the disease. Methods: This study includes 100 patients who admitted to our dermatology clinic with chronic urticaria, 100 health care providers and 100 healthy individuals. In patients with chronic urticaria, latex skin prick test was performed in addition to routine laboratory investigations. In the control group, prick test was performed only with latex. Changes in urticaria activity scores before and after latex containing products and cross reacting food restrictions were statistically compared in patients with urticaria. Results: Latex skin prick test was positive in 4 (4%) patients with urticaria and in 10 (10%) health care providers. Positive reaction was not observed in the healthy control group. Latex hypersensitivity in patients of urticaria was higher than healthy individuals, but the difference was not statistically significant. Urticaria activity scores did not change significantly after avoiding latex-cross reacting foods and latex-containing products. Conclusion: Latex hypersensitivity in patients with chronic urticaria was not found to be higher than the healthy individuals. In latex-sensitive patients, avoidance of latex-cross reacting foods and latex-containing products do not change the clinical course of the disease.
