Keloids are the result of a dysfunctional scarring process that leads to excessive deposition of extracellular matrix in susceptible individuals, causing them physical, psychological, and social discomfort. Many studies have investigated various aspects of keloid physiopathology; however, the relationship between dietary components and keloids has not received much attention. The present literature review was conducted to examine the available evidence related to the relationships between nutrition/nutrients and keloids. Findings from in vitro and in vivo studies indicate possible associations exist between keloids and fatty acids, soluble fibers, and phytochemicals. However, these relationships have not been fully explored and new studies need to be carried out before any efficient diet-based therapy can be prescribed for the prevention and treatment of keloids.

Keloids are abnormal scars formed due to fibroblast dysfunction and excessively deposited extracellular matrix (ECM). Despite the unclear process leading to the occurrence of keloids, several studies have demonstrated that histamine and its H1 receptor can effectively regulate fibroblast functions, contributing to keloid formation. Chlorpheniramine maleate (CPM) as a first-generation H1 antihistamine has been widely applied in symptomatic treatment of allergic conditions but its effects on keloids are unknown.

Background: Keloid is a benign skin tumor that result from abnormal wound healing and excessive collagen deposition. The pathogenesis is believed to be linked to genetic predisposition and immune imbalance, although the precise mechanisms remain poorly understood. Current therapeutic approaches may not consistently yield satisfactory outcomes and are often accompanied by potential side effects and risks.

Background: Fibrotic skin disease represents a major global healthcare burden, characterized by fibroblast hyperproliferation and excessive accumulation of extracellular matrix components. The immune cells are postulated to exert a pivotal role in the development of fibrotic skin disease. Single-cell RNA sequencing has been used to explore the composition and functionality of immune cells present in fibrotic skin diseases.

Purpose: The objective of this study is to investigate the clinical efficacy of sequentially comprehensive treatment based on surgery and to furnish clinical evidence for the management of keloids.
Patients And Methods: The patients with keloids were retrospectively analyzed who underwent surgery-based sequentially comprehensive treatment at the Plastic Surgery Department of Shandong Provincial Hospital from January 2018 to August 2021. The recurrence rate and incidence of adverse reactions were explored for all the included patients.

Urethral strictures and bladder neck contractures (BNCs) can be significantly morbid for patients and may require intervention for effective urinary drainage. We hypothesized patients with abnormal scarring disorders, such as keloids or hypertrophic scars, are at elevated risks of urethroplasty failure as well as postprocedural urethral strictures and BNCs. We queried the TriNetX database to determine the risk of urethroplasty failure for patients with abnormal scarring disorders compared to controls.
