Aim Current quarantine conditions are a difficult process for individuals and can worsen the psychological state. Increased psychosocial stress can affect the course of many common “stress‐sensitive” skin conditions. This study examined the possible effects of COVID‐19 on hair and scalp diseases such as telogen effluvium (TE), alopecia areata (AA), and seborrheic dermatitis (SD) in individuals who had to stay at home for a long time and the patients’ methods of dealing with these diseases. Methods The study was conducted using an online questionnaire. All the individuals were asked questions about pre and post‐pandemic TE, AA, and SD. Participants with complaints were asked what they did for treatment. Results During the pandemic, TE was seen in 27.9% of the participants, AA on the scalp was seen in 2.8%, AA on the face was seen in 2.5% and SD was seen in 19.9%. Applying to a dermatologist for complaints during the pandemic was lower than before pandemic. TE was higher in women before and during the pandemic Conclusion It was found that the rates of referring to a dermatologist for the complaints before the pandemic varied between 15 and 28% and that these rates decreased significantly during the pandemic (2.5‐12.5%).

Longitudinal myocardial systolic function assessed by STE, which is a sensitive marker of subclinical ventricular dysfunction is impaired in BD. Increased NT-proBNP levels may be a sign of subclinical ventricular dysfunction in these patients.

Xerosis and pruritus are common problems in HD-dependent patients. The early recognition of cutaneous signs can relieve suffering and decrease morbidity.

Aim In this study, we compared the current diagnoses of patients admitted to the dermatology outpatient clinic with the diagnoses during the non‐pandemic period, and we examined the effect of COVID‐19 on the patient profile. Methods Diagnoses were compared by examining the patient files of the 3‐month period when the pandemic was influential in our country and the 2‐week non‐pandemic period corresponding to the same season a year ago. The outpatient diagnoses in the first month and the last month of the 3‐month pandemic period were also compared. Results During the 3‐month pandemic process, the most common reasons for applying to the outpatient clinic were acne, urticaria, psoriasis, and allergic/irritant contact dermatitis. Urticaria, psoriasis, allergic/irritant contact dermatitis, scabies, liken planus, mycosis fungoides, zona zoster, recurrent aphthous stomatitis and polymorph light eruption were statistically more common in the pandemic period. Moreover, acne, other eczematous dermatities, verruca, androgenic alopecia, and melanocytic nevus diagnoses were found to decrease statistically during the pandemic period when compared with the non‐pandemic period. Conclusion Unlike other studies, the present study evaluated the patient diagnoses during the pandemic period and the period a year before and discussed the possible reasons for the changes in patient profiles.

Background Teledermatology is an alternative medical science that allows evaluation of patient's clinical information over a distance without requiring face‐to‐face examination. Due to COVID‐19, social distancing has become important these days, and teledermatology can help physicians and patients in overcoming the barriers of accessing health care. Aim In this study, we aim to evaluate how dermatologists in our country have viewed and experienced teledermatology during the pandemic through surveys. Patients/Methods The study was carried out by using an online survey for evaluating the teledermatology experiences of dermatologists in Turkey and how they have viewed teledermatology during the 2‐month pandemic period and the 2‐month prepandemic period. Results The number of patients evaluated with teledermatology methods was found to be significantly higher in the pandemic period when compared with the prepandemic period. The rates of using video calls with mobile phone and online video calls were found to be significantly higher in the pandemic period when compared with the prepandemic period. Conclusion Our study results show that the teledermatology method had a higher rate of usage compared to before the pandemic.

The incidence of tuberculosis and extrapulmonary forms of this disease is increasing all over the world. Lupus vulgaris is the most prevalent form of cutaneous tuberculosis in Europe and the Middle East. Papulonecrotic tuberculid, the most common form of hyperergic response to mycobacteria or their fragments, is uncommon in children. We report lupus vulgaris with papulonecrotic tuberculid in a 12-year-old girl who had a 3-year history of slowly growing plaques on her trunk, extremities, and the tip of her nose and papuloulcerative lesions over her entire body. A skin biopsy specimen showed minimally caseating granulomatous inflammation. Staining for acid-fast bacilli was negative in both plaques and papules. Polymerase chain reaction identified Mycobacterium tuberculosis DNA in the patient's sputum, gastric fluid, and plaques and was negative in the papules. She was started on antituberculous therapy with four drugs and her lesions responded rapidly.

Androgenetic alopecia (AGA) is a progressive hair loss disease that occurs with the effect of androgens and genetic predisposition. Hair thinning and hair loss affect people's self-confidence and self-image more than is thought. In these patients, platelet rich plasma (PRP) treatment is used in addition to the limited medical treatments available. However, there is a lack of standardization for the application method of PRP treatment in the literature. The number of studies in which objective data and hair analysis parameters were revealed to demonstrate the effectiveness of PRP treatment is also very limited. In this study, it was aimed to show the efficacy of PRP treatment with trichoscan data in AGA patients and to compare dermapen-mediated microneedling and point-by-point technique injection application methods. The study was conducted with 62 male AGA patients, aged between 18 and 55 years, who applied to the University Faculty of Medicine, Department of Dermatology, and ranged from Norwood-Hamilton Stage II-V. The patients were randomly divided into two groups and one group was given microneedling with a dermapen, an electrical device that makes automatic needling, and the other group was given manual injection with point-by-point technique with a 30-gauge needle. Before the first treatment, each patient underwent a trichoscan hair analysis evaluation. A total of four sessions of PRP treatment were performed, as three sessions at 2-week intervals and the fourth session 1 month after the last session. The mean age of the cases was 33.13 ± 6.36. According to Norwood-Hamilton staging, stage III was detected with the highest rate of 46% (29). Hair pulling test became significantly negative after treatment (p < 0.05). Statistically significant differences were found in trichoscan analysis parameters for hair count, hair density, terminal hair count, and terminal hair density in both groups compared to pretreatment (p < 0.05). Between the groups, a statistically significant difference was found between the averages of anagen hair, telogen hair, and hair length in the dermapen treated group compared to the group treated with the point-by-point technique. In our study, the efficacy of PRP treatment for AGA patients was demonstrated by trichoscan parameters. Among the PRP application methods, dermapen-mediated application was found to be superior to

Our study has shown that LA mechanical functions and volumes are impaired in BD. These results may be an early form of subclinical cardiac involvement in patients with BD who have no clinical evidence for cardiovascular disease.
