Objective: Although the etiology of rosacea is not known exactly, it is thought as a multifactorial disease. Demodex spp. are asymptomatic saprophytic ectoparasites living in hair follicles and sebaceous glands. The aim of this study was to investigate the frequency of Demodex spp. in patients with rosacea and compare with the control group by using superficial skin biopsy method. Methods: Seventy seven patients with rosacea and 31 control patients were included in the study. In patients, for the determination of density of Demodex spp., non-invasive standard superficial skin biopsy method was applied. Detection of ≥5/cm 2 Demodex spp. was considered positive. Results: The mean age of the patients was 44.5±14.6 years and the mean age of the control group was 48.2±14.9 years. Of the patients, 55.1% had erythema-telangiectatic type, 43.5% had papulopustular type, and 3.9% had fimatous type lesions. Demodex infestation was positive in 33.8% of the patients with rosacea and this rate was 9.7% in the control group. Difference was statistically significant. There was no significant difference in Demodex spp. positivity in terms of gender in patients with rosacea. Conclusion: The importance of Demodex infestation in patients with rosacea has been increasing in recent years. Considering some studies conducted in our country, we think that the investigation of Demodex spp. in patients who are considered to have rosacea will be beneficial in the terms of early diagnosis and treatment.

The aim is to comparatively evaluate the results of simultaneous conjunctiva and oropharynx-nasopharynx (ONP) swabs in patients who had presented to the outpatient department with a suspicion of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). An ONP sample was obtained following bilateral conjunctiva swabs in 85 subjects with a contact history or symptoms but unknown SARS-CoV-2 status and with no ocular symptoms or findings. The results were evaluated according to the patient's symptoms and how the swab was taken. The conjunctiva swab was positive in 29 (34.1%) cases and the ONP swab in 20 (23.5%) cases. Both methods produced positive results in 11 (14.1%) cases. The mean cycle threshold (C t ) value was 30.15 ± 3.41 in symptomatic cases and 33.62 ± 1.76 in asymptomatic cases (p = .008). The mean C t value was 24.37 ± 3.48 when only the How to cite this article: Gunduz A, Firat M, Turkoglu G.Comparison of the simultaneous conjunctiva and oropharynx-nasopharynx swab results in patients applying to the SARS-CoV-2 outpatient clinic for the first time.

Background and Design:Erythrasma is a superficial, local, mild and chronic skin infection caused by Corynebacterium minutissimum. Interdigital variant is the most frequent site for bacterial infection of the feet and it is the most common form of erythrasma. It frequently involves moist and closed intertriginous areas together with fissure or squama. The purpose of this study is to research the frequency of erythrasma in patients who refer with interdigital maceration and who are generally considered to have tinea pedis. Materials and Methods:The study was conducted between 15 January 2018 and 15 April 2018. A total of 116 patients who referred with the complaint of interdigital maceration were included in the study. A questionnaire form including demographic information were completed for all patients. All patients were examined with Wood lamp, smears taken were stained with Gram staining and examined under direct microscopy with 20% potassium hydroxide. Results: Of all the 116 patients with interdigital maceration, 97 (83.6%) were diagnosed with erythrasma. Of these 97 erythrasma patients, 66 (68%) were male, 31 (32%) were female and the average age was, 48.27±16.29 (minimum age: 20, maximum age: 86 years). Fifteen patients had only Gram staining positive, while 7 patients had only Wood examination positive. Seventy-five patients had both Wood examination and Gram staining positive. Fungal infection was found in direct potassium hydroxide examination of 65 (67%) patients. Conclusion: Erythrasma is frequently seen in patients with maceration. It is important to use Wood light examination and Gram staining together to increase diagnostic accuracy. In addition, it should be kept in mind that erythrasma can be seen with candida and dermatophyte infection when interdigital areas are affected. Amaç: EritrazmaCorynebacterium minutissimum'un sebep olduğu yüzeyel, lokalize, hafif ve sıklıkla kronik seyreden bir deri enfeksiyonudur. İnterdijital varyantı ayağın en yaygın bakteriyel enfeksiyonudur ve eritrazmanın en yaygın formudur. Sıklıkla fissür ya da skuamla beraber interdijital bölgelerin asemptomatik, kronik maserasyonu ile seyreder. Bu çalışmanın amacı interdijital maserasyonla başvuran ve genellikle tinea pedis düşünülen hastalarda eritrazma sıklığını araştırmaktır. Gereç ve Yöntem: Çalışma 15 Ocak 2018 ile 15 Nisan 2018 tarihleri arasında yapıldı. Çalışmada interdijital maserasyon şikayeti ile başvuran 116 hasta yer aldı. Tüm hastalar için demografik bilgileri içeren anket formu dolduruldu. Tüm hastalar Wood lambası ile muayene edildi, alınan yaymalar Gram boyamayla boyandı ve %20 potasyum hidroksit ile direkt mikroskopik inceleme yapıldı. Bulgular: İnterdijital maserasyonu olan 116 hastanın 97'si (%83,6) eritrazma tanısı aldı. Bu 97 eritrazmalı hastanın 66'sı erkek (%68), 31'i kadındı (%32) ve ortalama yaş: 48,27±16,29 (minimum yaş: 20, maksimum yaş: 86 yıl) idi. Eritrazma tanısı alan 97 hastanın 15'inde sadece Gram boyama, yedi hastada ise sadece Wood muayenesi pozitifti. Yetmiş beş hastada ise hem Wood muayene...
