In 31 patients with hypertrophic scars or keloids, a side by side test was carried out to check the efficacy of an occlusive dressing technique using cream which did not contain silicone oil, versus a simple application of vaseline, used as a control. In all cases, the cream treated areas of scar and keloid demonstrated a remarkable improvement over that of the vaseline treated area. These findings strongly suggest that the mechanisms of hydration and occlusion are the main basis of the therapeutic action of this method in treating hypertrophic scars and keloids.

Hypertrophic scar (HS) is a common fibroproliferative disorders with no fully effective treatments. The conversion of fibroblasts to myofibroblasts is known to play a critical role in HS formation, making it essential to identify molecules that promote myofibroblast dedifferentiation and to elucidate their underlying mechanisms. In this study, we used comparative transcriptomics and single-cell sequencing to identify key molecules and pathways that mediate fibrosis and myofibroblast transdifferentiation.

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.

This study investigated the knowledge, attitude, and practice (KAP) of aesthetic medicine practitioners concerning laser and/or light therapy for hypertrophic scars. Conducted at Hebei Medical University Third Hospital from December 25, 2023, to January 7, 2024, the cross-sectional study utilized a self-administered questionnaire to gather socio-demographic data and KAP scores. A total of 424 valid questionnaires were collected, with 220 (52.

Background: Hypertrophic scar (HS) is a severe skin fibrosis. Transplanting stem cells carrying anti-fibrotic cytokine genes, like interferon-gamma (IFN-γ), is a novel therapeutic strategy. Human amniotic epithelial cells (hAECs) are ideal seed cells and gene vectors.

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.
