Functional, aesthetic, and sensory postoperative complications of female genital gender affirmation surgery: A prospective study.

Background: Female genital gender affirmation surgeries have increased in recent years. Prospective studies with homogeneous standardized techniques and outcomes assessment are scarce in the current literature. This study aims to: 1) report the functional, aesthetic, and sensory postoperative complications (POCs) of primary genital gender confirmation surgeries performed on transgender women and 2) compare functional and aesthetic POCs amongst three vaginoplasty techniques: inverted penile skin, penoscrotal skin graft, and pedicled intestinal flap vaginoplasty.

Cosmetic Revision Surgeries after Transfeminine Vaginoplasty.

Background: Vaginoplasty is the most frequent genital gender-affirming surgery. Although both functional and aesthetic outcomes after transfeminine vaginoplasty have improved over the years, cosmetic revision surgeries demand after transfeminine vaginoplasty appears to be increasing and requires updated knowledge.

Methods: All patients who underwent vulvar cosmetic revision surgeries at our institution following transfeminine vaginoplasty from January 2014 to April  2022 were studied.

Up-to-date approach to manage keloids and hypertrophic scars: a useful guide.

Keloids and hypertrophic scars occur anywhere from 30 to 90% of patients, and are characterized by pathologically excessive dermal fibrosis and aberrant wound healing. Both entities have different clinical and histochemical characteristics, and unfortunately still represent a great challenge for clinicians due to lack of efficacious treatments. Current advances in molecular biology and genetics reveal new preventive and therapeutical options which represent a hope to manage this highly prevalent, chronic and disabling problem, with long-term beneficial outcomes and improvement of quality of life.

Human Wharton's jelly mesenchymal stem cells promote skin wound healing through paracrine signaling.

Introduction: The prevalence of nonhealing wounds is predicted to increase due to the growing aging population. Despite the use of novel skin substitutes and wound dressings, poorly vascularized wound niches impair wound repair. Mesenchymal stem cells (MSCs) have been reported to provide paracrine signals to promote wound healing, but the effect of human Wharton's jelly-derived MSCs (WJ-MSCs) has not yet been described in human normal skin.

New molecular medicine-based scar management strategies.

Keloids and hypertrophic scars are prevalent disabling conditions with still suboptimal treatments. Basic science and molecular-based medicine research have contributed to unravel new bench-to-bedside scar therapies and to dissect the complex signalling pathways involved. Peptides such as the transforming growth factor beta (TGF-β) superfamily, with Smads, Ski, SnoN, Fussels, endoglin, DS-Sily, Cav-1p, AZX100, thymosin-β4 and other related molecules may emerge as targets to prevent and treat keloids and hypertrophic scars.

Effect of human Wharton's jelly mesenchymal stem cell paracrine signaling on keloid fibroblasts.

Keloid scars are abnormal benign fibroproliferative tumors with high recurrence rates and no current efficacious treatment. Accumulating evidence suggests that human umbilical cord Wharton's jelly-derived mesenchymal stem cells (WJ-MSCs) have antifibrotic properties. Paracrine signaling is considered one of the main underlying mechanisms behind the therapeutic effects of mesenchymal stem cells.
