Deficient serum 25(OH)D levels are present in patients with AA and inversely correlate with disease severity. Accordingly, screening patients with AA for vitamin D deficiencies seems to be of value for the possibility of supplementing these patients with vitamin D.

Background Generalized pustular psoriasis (GPP) is a rare and severe inflammatory disease characterized by widespread and superficial sterile pustules on an erythematous background. Objectives This multicentre study aimed to determine the clinical profile and course in a large cohort of patients with GPP. Methods One hundred and fifty‐six GPP patients (mean age, 44.2 ± 18.7 years) who met the diagnostic criteria of the European Consensus Report of GPP were included in the study. Sociodemographic characteristics, quality of life, triggering factors of the disease, clinical, laboratory, treatment and prognostic features were evaluated. Results 61.5% of the patients were female. The rate of working at or below the minimum wage (≤$332.5/month) was 44.9%. Drugs (36.5%) were the most common trigger. While hypocalcaemia (35.7%) was the most important cause of GPP during pregnancy, systemic steroid withdrawal (20%) was the most frequently reported trigger for infantile/juvenile and mixed‐type GPP (15%) (P < 0.05). Acute GPP (53.8%) was the most common clinic. Nails were affected in 43.6% of patients, and subungual yellow spots (28.2%) were the most common change. In annular GPP, fever (P < 0.001) and relapse frequency (P = 0.006) were lower than other subtypes, and the number of hospitalizations (P = 0.002) was lower than acute GPP. GPP appeared at a later age in those with a history of psoriasis (P = 0.045). DLQI score (P = 0.049) and joint involvement (P = 0.016) were also higher in this group. Infantile/juvenile GPP was observed in 16.02% of all patients, and arthritis was lower in this group (24.4 vs. 16%). GPP of pregnancy had the worst prognosis due to abortion observed in three patients. Conclusions Recent advances in treatment have improved mortality associated with GPP, but abortion remains a significant complication. Although TNF‐α inhibitors have proven efficacy in GPP, they can also trigger the disease. Mixed‐type GPP is more similar to acute GPP than annular GPP with systemic manifestations and course.

Introduction: Psoriasis significantly affects the patients’ quality of life, which often leads patients to seek online information about this disease. Objectives: To explore the habits of patients with psoriasis related to their use of SM and the internet to obtain information about their disease. Methods: 1,520 patients completed the survey and the Dermatology Life Quality Index (DLQI) questionnaire. The Psoriasis Area Severity Index scores (PASI) and clinical data of the patients were recorded by their physicians. Results: Of the 1,114 patients that reported using social media (SM) and the internet, 48.38% regularly and 31.14% sometimes resorted to obtain information about psoriasis. The use of SM and the internet for psoriasis was statistically significantly higher among young people (p=0.000), those with university or higher education (p=0.009), higher DLQI (p=0.000) and PASI (p=0.011) scores, facial (p=0.050), scalp (p=0.032), hand (p=0.048), genital (p=0.001) and inverse (p=0.000) involvement, and arthralgia/arthritis (p=0.006). The participants mostly used the Google (86%) and Facebook (%41). More than half the participants (62.8%) expected dermatologists to inform society that psoriasis is not contagious. Conclusion: The internet and SM being widely available and offering substantial information to be easily accessed make it very attractive for patients to use these platforms to investigate diseases, including psoriasis. If what is presented on SM conflicts with what the physician says, patients mostly trust the latter, but at the same time, they tend not to share the results of their online inquiries with their physicians.

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.
