Background Acne vulgaris (AV) may affect external appearance and significantly deteriorate the quality of life of patients. Therefore, patients make various inquiries about their disease and seek treatment options. Aims To investigate the social media usage habits of patients with AV concerning their diseases, and their recommendations for dermatologists related to social media use. Methods A total of 1609 patients with AV completed the survey prepared by the authors and the Cardiff Acne Disability Index questionnaire. The Food and Drug Administration severity scores and clinical information of the patients were noted by their physicians. Results Of the 1,489 patients who stated that they used social media, 46.31% regularly and 28.77% sometimes referred to these sources to make inquiries about AV. Social media usage for AV was statistically significantly higher in women, participants with short term and severe disease, those with a moderate income level, and those using topical treatment and cosmetics. They mostly used Google (67%), Instagram (54%), and YouTube (49%). While 76% of the participants stated that they did not share what they saw on the Internet with their doctor. Of the respondents, 18.5% were trying to contact their dermatologists through the Internet, and 69.73% would prefer experts such as dermatologists to post–AV‐related content. Conclusions Our study shows that patients frequently resort to social media to seek information about AV. In the changing digital world order, it is observed that there is a need for dermatologists to use social media more actively to share accurate information about AV.

Background Skincare products and cosmetic procedures are used as an adjunct or complementary to conventional drug therapy for acne vulgaris (AV). Objective To evaluate the use of skincare products and the frequency of cosmetic procedures in AV treatment. Methods A total of 1,755 patients with AV completed the survey prepared by the researchers and the Cardiff Acne Disability Index (CADI) questionnaire. The clinical findings and the Food and Drug Administration (FDA) severity scores were recorded by the dermatologists. Results For AV, 66.7% of the patients stated that they used skincare products and 26.7% had undergone cosmetic procedures. The use of skincare products was statistically significantly higher in women (female: 74.5%, male: 57.7%, p < 0.0001); older people (users: 22 ± 7.6years, non‐users: 21.2 ± 5.7 years, p < 0.0001); patients with a higher CADI score (users: 7 ± 3.7, non‐users: 6.9 ± 4.3, p = 0.010); FDA severity score 2 and 3 (FDA‐1: 58.1%; FDA‐2: 72.4%, FDA‐3: 73%, FDA‐4: 67%, p < 0.0001); long‐term disease (users: 57 ± 43 months; non‐users: 47.7 ± 42.3 months, p < 0.0001); facial involvement (present: 70.2%, absent: 51.4%, p = 0.017); high income levels (users: 73.5%; non‐users: 26.5%, p = 0.001); and graduate or post‐graduate degrees (undergraduate≤%62.8, graduate≥%76.8, p < 0.0001). The rate of cosmetic procedures was higher in those with higher CADI scores (users: 7.8 ± 3.8; non‐users: 7.1 ± 3.96, p < 0.0001); older patients (users: 22.7 ± 10.7 years; non‐users: 21.3 ± 5 years, p < 0.0001); high school (25.6%); and graduate (28.9%) education (p = 0.043), those with lower disease severity (FDA‐1: 31.1%; FDA‐2: 28.5%, FDA‐3: 27.1%, FDA‐4: 20.4%, p = 0.022); smokers (smokers: 32.5%; non‐smokers: 25.5%, p = 0.020), and those with AV in the family (present: 29.8%; absent: 24.2%, p = 0.009). The patients most frequently used cleansers (85.2%) as cosmetic products, and most commonly underwent skincare treatment (71%) as an interventional procedure. They mostly learned about such products and methods from the Internet, and 33.3% of the participants had undergone procedures performed by non‐physicians. Conclusion The patients generally choose skincare products as a result of their Internet search and sometimes have these procedures performed by non‐physicians. Dermatologists should be aware of this situation and inform their patients about appropriate products and procedures.

Background:The rate of cosmetic procedures and use of skincare products is considered to be affected during the pandemic period; however, this has not been investigated yet.Objective: To determine whether the ongoing pandemic has changed people's habits related to skincare products and cosmetic procedures. Methods:We conducted a multicenter survey study covering both private and public hospitals. Sociodemographic characteristics and clinical diagnoses of the patients were noted by dermatologists. A survey was used to determine the type and application areas of skincare products and cosmetic procedures before and during the pandemic, whether the patients were concerned about being infected, and any change in the make-up habits of female patients.Results: Of the 1437 patients, 86.7% presented to the hospital due to dermatological complaints and 13.3% for cosmetic procedures. The rate of those that did not use skincare products was 0.05% before and 0.06% during the pandemic. Of the participants, 43.2% had undergone cosmetic procedures before and 38.1% during the pandemic.For both periods, the most frequent cosmetic procedure applied was laser epilation, followed by skincare treatment and chemical peeling. While undergoing these procedures, 34.9% of the patients were concerned about contracting coronavirus. Conclusion:There was no significant difference in the use of skincare products and cosmetic procedures before and during the pandemic. The majority of the patients continued to undergo these procedures despite their fear of being infected. This

Background: Acne vulgaris (AV) is among the common skin diseases for which patients refer to complementary and alternative medicine (CAM). Aims and Objectives: To investigate the approaches to CAM methods and factors believed to increase the disease in 1,571 AV patients. Materials and Methods: The sociodemographic characteristics of the patients and disease severity according to the Food and Drug Administration criteria were recorded. The Cardiff Acne Disability Index (CADI) was used to assess the impact of acne on the patient's life and the history of CAM use was noted. The patients also listed the factors that they thought worsened their disease and reported their gluten-free diet experiences. Results: Of all the patients, 74.41% had a history of using CAM methods. CAM use was significantly higher in women, patients with severe AV, those with a higher CADI score and non-smokers. As a CAM method, 66.37% of the patients reported having used lemon juice. The respondents most frequently applied CAM methods before consulting a physician (43.94%), for a duration of 0–2 weeks (38.97%). They learned about CAM methods on the internet (56.24%) and considered CAM methods to be natural (41.86%). The patients thought that food (78.55%) and stress (17.06%) worsened their disease. They considered that the most common type of food that exacerbated their symptoms was junk food (63.84%) and a gluten-free diet did not provide any benefit in relieving AV (50%). Conclusion: Physicians need to ask patients about their CAM use in order to be able to guide them appropriately concerning treatments and applications with a high level of evidence.

Costello syndrome (CS) was described in 1977 by Costello who reported two unrelated children with a new syndrome comprising short stature, redundant skin of the neck, palms, soles, and fingers, curly hair, papillomata around the mouth and nares, and mental retardation. Several additional cases have been reported since then. Herein we report two patients with Costello syndrome; one of these patients had associated mesenteric cyst.
