This study observed that exposing human hair keratins to heat or UV treatments led to modifications in cysteine residues, disrupting crucial disulphide bonds and potentially reducing the structural integrity of hair similar to prolonged styling or sunlight exposure.

This case report describes a preterm newborn with lamellar ichthyosis, detailing management with acitretin, vitamin D, and emollients, and emphasizes the importance of regular monitoring due to potential adverse effects of long-term retinoid therapy.

This research review found that climate change exacerbates skin conditions like photoaging, inflammatory dermatoses, and skin cancers by causing oxidative stress and inflammation, suggesting that dermatological practices should incorporate environmental and multicultural considerations to optimize patient outcomes in diverse populations.

This study found that phototherapy was more effective for patients with the multiple or totalis types of alopecia areata, with whole-body phototherapy potentially benefiting those with refractory universalis type.

This source discusses autoimmune disorders, noting that the presence of autoantibodies can precede disease development, especially in genetically predisposed individuals, with various triggers like vitamin D deficiency and UV exposure potentially influencing onset and severity.

This study reported that urban pollution accelerates facial wrinkle development and increases pigmentation severity in Chinese women over 30, whereas UV exposure affects these signs from age 20. After 45, pollution becomes a key contributor to skin aging.

This study reviewed phototherapy data for pediatric patients over 5 years, finding psoriasis as the most common condition treated. The researchers reported a lower incidence of side effects compared to similar studies but also noted lower treatment response rates.

Stopping certain drugs can improve skin conditions, arsenicosis affects over half of a Bangladeshi village, males are more vulnerable, and certain treatments are effective for warts, acne, and psoriasis. Smoking and drinking are linked to psoriasis in men, a cream helps with a type of skin cancer, and low iron levels don't directly cause chronic hair loss in women.
