    (2014) Eryilmaz, Aydolu; Durdu, Murat; Baba, Mete; Yildirim, Fatma E.; https://orcid.org/0000-0001-6554-519X; https://orcid.org/0000-0003-1247-3932; https://orcid.org/0000-0001-6801-8491; 23557278; AAK-5324-2021; H-9068-2019; HGU-2777-2022; C-4705-2014
    Background The Tzanck smear is a simple, easily applicable, rapid, and inexpensive test for the diagnosis of erosive vesiculobullous, tumoral, and granulomatous diseases. The diagnostic accuracy of the Tzanck smear is known, but its diagnostic reliability has been evaluated only in herpetic infections and basal cell carcinoma. Objectives The aim of this study was to evaluate the diagnostic reliability of the Tzanck smear in erosive vesiculobullous, tumoral, and granulomatous diseases. Methods Patients evaluated by Tzanck smear at Bakent University Faculty of Medicine, Department of Dermatology, between February 2009 and July 2010, were included. Three dermatologists were involved in the study. Dermatologist A performed a clinical dermatologic examination, took the smear material, made a clinical diagnosis, and compared the clinical and cytological diagnoses. Dermatologists B and C evaluated the smears. Agreement between the latter two dermatologists on the cytological diagnoses was determined. Results In 500 patients, a total of 272 (54%) erosive vesiculobullous, 190 (38%) tumoral, and 38 (8%) granulomatous lesions were diagnosed. The diagnostic reliability of the Tzanck smear was reasonably substantial (=0.59) for all types of lesions, substantial for erosive vesiculobullous (=0.79) and granulomatous (=0.68) lesions, and moderate (=0.50) for tumoral lesions. Conclusions The Tzanck smear may be used for the evaluation of erosive vesiculobullous and granulomatous lesions with brief training. However, the evaluation of tumoral lesions by Tzanck smear requires more experience.

    Efficacy and Safety of Diphenylcyclopropenone Alone or in Combination with Anthralin in the Treatment of Chronic Extensive Alopecia Areata: A Retrospective Case Series
    (2015) Durdu, Murat; Ozcan, Deren; Baba, Mete; Seckin, Deniz; 0000-0002-7450-6886; 0000-0003-1247-3932; 25653027; AAQ-6649-2021; H-9068-2019; HGU-2777-2022
    Background: Some patients with chronic extensive alopecia areata (AA) may be refractory to topical immunotherapy. Combination therapy is recommended for such patients. Efficacy and safety of a combination therapy with diphenylcyclopropenone (DPCP) and anthralin in chronic extensive AA is unknown. Objective: We sought to determine whether the combination therapy of DPCP and anthralin is superior to DPCP alone in chronic extensive AA. Methods: We retrospectively analyzed the efficacy, side effects, and relapse rates of DPCP (alone or with anthralin) in chronic extensive AA. Results: A total of 47 patients (22 were treated only with DPCP, and 25 with DPCP and anthralin for at least 30 weeks) were evaluated. Complete hair regrowth was observed in 36.4% and 72% of the patients who received DPCP and combination therapy, respectively (P = .01). Hair regrowth duration was shorter with combination therapy (P = .01). Regrowth rates of the eyebrows, eyelashes, and beard in patients on combination therapy were higher than those in patients on DPCP (P = .01). Side effects such as folliculitis, hyperpigmentation, and staining of skin, hair, and clothes were more common in combination therapy group. Limitations: The retrospective design and small number of patients are limitations. Conclusion: Combination therapy with DPCP and anthralin is superior to DPCP alone in chronic extensive AA.
