Introduction: Hidradenitis suppurativa (HS) is a chronic skin disease whose impact on skin homeostasis has not been adequately studied at present. Knowledge about how skin function changes in these patients, and could be of interest not only to improve the topical management of the disease, but also as an objective measure of disease activity. The aim of this study was to compare skin homeostasis and the epidermal barrier function in lesional and healthy skin areas of patients with HS.
Methods: We conducted a cross-sectional study. Skin homeostasis and the epidermal barrier function of lesions were assessed in HS patients using validated tools. A healthy perilesional skin control was assigned to each lesion to compare skin homeostasis parameters.
Results: A total of 43 patients were included: 22 nodules, 10 abscesses and 25 draining tunnels were measured. The male-to-female ratio was 20:23, and the mean age, 35.95 years (SD, 14.82). Increased transepidermal water loss (TEWL) and erythema were found in nodules, abscesses and draining tunnel vs healthy skin. A direct association was observed between inflammatory nodules TEWL and IHS4 stage. In draining tunnels, a direct association was observed between TEWL and smoking. A trend of increasing TEWL values was observed as a function of Hurley stage.
Conclusion: HS lesions exhibit epidermal barrier dysfunction that depends on the severity of inflammatory activity. These results could be useful to develop objective classification systems for the severity and degree of involvement of HS or help in the development of vehicles for specific drugs, antiseptics and dressings for the management of this disease.

Inherited retinal diseases (IRDs) are a genetically heterogeneous group of Mendelian disorders that often lead to progressive vision loss and involve approximately 300 distinct genes. Although variants in these loci account for the majority of molecular diagnoses, other genes associated with IRD await molecular identification. In this study, we uncover bi-allelic assortments of 23 different (22 loss-of-function) variants in AP5Z1, AP5M1, and AP5B1 as independent causes of recessive IRD in members of 19 families from nine countries.

Skin aging is the most prominent phenotype of host aging and is the consequence of a combination of genes and environment. Improving skin aging is essential for maintaining the healthy physiological function of the skin and the mental health of the human body. Mitochondria are vital organelles that play important roles in cellular mechanisms, including energy production and free radical balance.

The human microbiota plays a significant role in health and the development of autoimmune diseases by maintaining gut-skin homeostasis through diverse microbial communities. Dysbiosis, or imbalance in these communities, is increasingly recognized as a contributing factor in the pathogenesis of autoimmune and inflammatory diseases, including psoriasis. Psoriasis is characterized by immune dysregulation, leading to red and scaly plaques that significantly reduce patients' quality of life.

Obesity is associated with comorbidities including type 2 diabetes, chronic nonhealing wounds, and psoriasis. Normally, skin homeostasis and repair is regulated through the production of cytokines and growth factors derived from skin-resident cells including epidermal γδ T cells. However, epidermal γδ T cells exhibit reduced proliferation and defective growth factor and cytokine production during obesity and type 2 diabetes.

Primary hyperhidrosis (PH) is the presence of increased sweating in the absence of a physiological trigger or underlying identifiable pathological cause. The aim of this study was to assess the impact of primary hyperhidrosis on patients' quality of life in Damietta; one of Egypt's governorates. This cross sectional study included 302 patients aged between 8 and 35 years and fulfilling diagnostic criteria of primary hyperhidrosis.
