    (2014) Ozcan, Deren; Gulec, A. Tulin; https://orcid.org/0000-0002-7450-6886; 24636435; AAQ-6649-2021
    Background: Patients tend to be noncompliant with tap water iontophoresis (TWI), which is an effective treatment option for palmoplantar hyperhidrosis. Objective: To investigate compliance with TWI in patients with palmoplantar hyperhidrosis and identify the factors limiting its utility. Methods: The medical data of 22 patients treated with TWI for palmoplantar hyperhidrosis were collected. A telephone inquiry questioning overall satisfaction with the treatment and the reasons for discontinuation was conducted. Results: Sixteen patients completed the initial treatment period, and all responded well to the therapy. Eight patients started on the maintenance treatment, five of whom gave up before completing five sessions. The reasons for discontinuation were a lack of time in 12 patients, switching to home therapy in 3 patients, and side effects in 1 patient. Conclusion: Patients with palmoplantar hyperhidrosis are noncompliant with TWI, mainly due to a lack of time. They should be well informed before therapy and be encouraged to have a home device for maintenance.

    Evaluation of a Handheld Dermatoscope in Clinical Diagnosis of Primary Cicatricial Alopecias
    (2019) Kose, Ozlem Karadag; Gulec, A. Tulin; 31190216
    Introduction Clinical diagnosis of primary cicatricial alopecias presents difficulties. Studies regarding their trichoscopic features are scarce and mostly not comprehensive. The aim of this study is to evaluate the potential benefit of a handheld dermatoscope in clinical diagnosis of primary cicatricial alopecias. Methods In all, 69 patients with primary cicatricial alopecias were included in this prospective study. Preliminary diagnoses were established clinically, and confirmed by scalp biopsy in all cases. Trichoscopic examination was performed using a polarized-light handheld dermatoscope with tenfold magnification. The images were taken using a digital camera with threefold optical zoom. Results The following findings were significantly more common, or noted only, in particular types of primary cicatricial alopecias: "target" pattern blue-grey dots, perifollicular scaling, perifollicular cast in lichen planopilaris (n = 27); short vellus hairs, tufted hairs, crust formation, yellowish tubular scaling, pustule, red dots in folliculitis decalvans (n = 17); large keratotic yellow dots in discoid lupus erythematosus (n = 7); yellow dots, yellow dots with "three-dimensional" structure, black dots in dissecting cellulitis of the scalp (n = 6). Absence of vellus hairs was observed in patients with lichen planopilaris, frontal fibrosing alopecia, and discoid lupus erythematosus without a significant difference between the groups. Short vellus hairs were detected in all types, including frontal fibrosing alopecia (n = 7). Conclusion We suggest that a polarized-light handheld dermatoscope is useful for revealing several typical trichoscopic features of primary cicatricial alopecias that guide clinical diagnosis. As a novel observation, our data indicate that absence of vellus hairs is not an identifying feature for frontal fibrosing alopecia.

    Evaluation of Treatment Response by Using a Handheld Dermoscope in Patients with Alopecia Areata
    (2018) Gulec, A. Tulin; Kose, Ozlem Karadag
    Objective: Treatment response is variable in patients with alopecia areata, and may not be understood until significant hair growth is obtained. The aim of this study is to determine the potential benefit of handheld dermoscope in evaluating of treatment success in alopecia areata. Methods: Forty-nine patients who were diagnosed with alopecia areata were included in the study. Diagnosis was established clinically, and scalp biopsy was performed in doubtful cases. Dermoscopic examinations were performed by a polarized light and handheld dermoscope with 10-fold magnification. The images were taken by a digital camera with threefold optical zoom. Among 49 patients, 30 of them were followed-up during six months and concluded the study. Results: Of the 30 patients, 12 had a complete response to treatment (group 1), whereas 18 patients did not respond well to treatment or were remained completely responseless (group 2). When the trichoscopic findings were examined pretreatment, only thinning hairs were significantly more frequent in group 1 than group 2. The pre- and posttreatment findings of group 1 was shown that yellow dots, black dots, thinning hairs and broken hairs decreased or disappeared after the treatment, and this difference was statistically significant. In all of the patients in the first group, short terminal hairs were appeared at the end of treatment. Conclusion: According to our study, polarized light handheld dermoscope provides benefit for the evaluation of treatment success in patients with alopecia areata.

    Natural Thermal Spa Water Versus Hyperthermic Tap Water for Treatment of Recalcitrant Hand Warts in Organ Transplant Recipients: A Patient-Blinded, Comparative Preliminary Study
    (2018) Gulec, A. Tulin; 29528025
    Objectives: Cutaneous warts represent a major problem in organ transplant recipients because of their extensive involvement and persistent course. Current therapeutic modalities often fail to achieve a successful response in patients with warts. We experienced a case involving an organ transplant recipient with recalcitrant mosaic warts who presented with complete clearance of lesions in 3 days after thermal spa bathing. Here, we evaluated the efficacy of natural thermal water versus hyperthermic tap water for treatment of recalcitrant hand warts in organ transplant recipients. Materials and Methods: In this preliminary study, the right hands of 5 organ transplant recipients with hand warts were immersed in thermal water, while the left hands were soaked in tap water at 44 degrees C to 47 degrees C. Treatment involved three 45-minute sessions per week for 1 month. The total number and size of the warts and the hyperkeratosis severity grade were noted. Results: After 12 sessions, none of the patients exhibited any marked improvement in the size or number of warts, although 3 patients had a slight decrease in their hyperkeratosis severity grade. Conclusions: Our preliminary data indicate that neither thermal spa water nor hyperthermic tap water is effective for treatment of recalcitrant hand warts in organ transplant recipients. However, new trials using thermal water supplied from different geographical locations should be performed before this observation can be generalized.

    Skin Cancer Risk Awareness and Sun-Protective Behavior Among Solid-Organ Transplant Recipients
    (2018) Vural, Ayse Tuncer; Togral, Arzu Karatas; Kirnap, Mahir; Gulec, A. Tulin; Haberal, Mehmet; 0000-0001-8770-5721; 0000-0002-3462-7632; 29528028; AAQ-4123-2021; AAH-9198-2019; AAJ-8097-2021
    Objectives: Solid-organ transplant recipients are at an increased risk of developing skin cancer; this risk is due to long-term graft-preserving immunosuppressive therapy, and excessive sun exposure is a major contributing factor to this process. The aim of this study was to evaluate the skin cancer awareness and sun-protective behavior of solid-organ transplant recipients. Materials and Methods: In all, 70 consecutive solid-organ transplant recipients were evaluated regarding knowledge of their increased skin cancer risk and regarding the influence of this knowledge on their sun-protective practices, by applying a questionnaire during their routine check-up visits. Results: Of 70 solid-organ transplant recipients, 38 (54.3%) stated knowledge of hazardous consequences of sun exposure; however, only 28 (40%) had the knowledge of causal relationship between sun and skin cancer development. There were 31 patients (44.3%) who were unable to recall anybody giving any information to them about sun protection, and 40 patients (57.1%) had never visited a dermatology clinic. The 10 solid-organ transplant recipients (14.3%) who used sunscreen creams daily had been undergoing regular dermatologic examination. Regarding sun-protective clothing, only 8 patients (11.4%) had been wearing a suitable hat, long sleeves, and sunglasses when outdoors. There was a statistically significant difference between the groups who had visited a dermatology clinic versus those who had not regarding knowledge of sun protection, the causal relationship between sun exposure and skin cancer, the use of sunscreens, and use of sun-protective clothing (P < .05). Conclusions: Our data showed that dermatologic examination and education of patients about skin cancer development and sunscreen measures improved the sun-protective habits of solid-organ transplant recipients. Therefore, orderly visits once or twice a year should be strongly advised for this patient population by their medical care providers.
