Background: Acne vulgaris (AV) is a chronic, multifactorial inflammatory disease of the pilosebaceous unit brought on by hormonal imbalance, excessive sebum production, follicular hyperkeratinization, inflammation and Cutibacterium acne. Acne patients are characterized by alteration of the lipid profile. Apolipoprotein B gene (ApoB) plays an essential role in lipoprotein biosynthesis and multiple single-nucleotide polymorphisms (SNPs) in ApoB are associated with dyslipidemia.
Aim: The aim of this study was to estimate the alteration of lipid profiles in AV, determine the genetic association with lipid profile alteration by studying the ApoB gene polymorphisms, and to identify the exact haplotypes associated with acne and lipid profile alteration.
Subjects And Methods: In a case-control study consisting of 63 non-obese acne patients and 43 healthy controls, all participants underwent biochemical, anthropological assessments, and genetic analysis for ApoB polymorphisms.
Result: Our results indicate that serum ApoB and the lipid profile were higher in acne patients compared with healthy subject. The most common haplotypes in acne patients were rs562338 A/rs17240441 I/c.12669 A/rs1042034 G, whereas the most common haplotypes in healthy subjects were rs562338 G/rs17240441 D/c.12669 A/rs1042034 G. Patients with mild acne had higher serum ApoB levels p = 0.005. Also, the low-density lipoprotein cholesterol (LDL-C) level was higher in mild acne compared with other acne groups, with a highly significant variation of p ≤ 0.001.
Conclusion: We found a significant variation between the acne group and healthy controls in serum ApoB, triglycerides, total cholesterol and LDL-C. The most common haplotypes in acne patients are rs562338 A/, rs17240441 I/, c.12669 A/ and rs1042034 G, and there is a linkage disequilibrium between the four selected SNPs.

Objective: The aim of this study was to evaluate and validate the accuracy and performance characteristics of administrative codes in diagnosing autoinflammatory syndromes (AISs).
Methods: We identified potential AIS patients from the electronic medical records at the University of Iowa Hospital and Clinics and the Stead Family Children's Hospital using a screening filter based on the 10th edition of the International Classification of Diseases (ICD-10) codes and interleukin-1 antagonists. Diagnostic criteria for adult-onset Still disease, systemic juvenile idiopathic arthritis, Behçet disease (BD), familial Mediterranean fever (FMF), cryopyrin-associated periodic syndrome (CAPS), and SAPHO (synovitis, acne, pustulosis, hyperostosis, and osteitis) syndrome and chronic nonbacterial osteomyelitis (SAPHO-CNO) were reviewed for each patient.

Patients with progressing facial vitiligo who had been treated with upadacitinib, 308 nm excimer light and upadacitinib combined with 308 nm excimer light were selected for retrospective analysis and comparison of their efficacy and safety. Efficacy was evaluated using the Vitiligo Area Severity Index (VASI) and Dermatology Life Quality Index (DLQI) at baseline, after 8 weeks, and after 20 weeks. The progression of skin lesions was monitored through reflectance confocal microscopy (RCM), while adverse reactions were documented.

Sexual and gender minority (SGM) cancer survivors face unmet care needs in accessing cancer health information and social support despite high satisfaction with treatment. SGM patients often delay care due to concerns of discrimination in healthcare settings, though the care experiences of SGM skin cancer survivors are less known. SGM individuals, particularly sexual minority men, report higher skin cancer prevalence and related risk behaviors than heterosexual men.

This includes findings of poor body image, as a result of the change in physical appearance to the skin. However, there is limited qualitative research in the UK that explores how young women with skin conditions experience unique psychosocial impacts, including body image issues.

Acne leads to significant social withdrawal, depression, and disfiguring scars in many cases. Available treatments are characterized by high rates of relapse, dangerous side effects, and social stigma, which often leads to poor patient compliance and treatment failure.
