Keloid and hypertrophic scars are difficult to manage and remain a therapeutic challenge. Verapamil has shown a great potential in the management of keloid and hypertrophic scars. Comparing with conventional corticosteroid injections, verapamil could improve the appearance of keloid and hypertrophic scars, and is associated with a lower incidence of adverse effects. Is verapamil an effective al...

Keloid and hypertrophic lesions are both types of scarring pathologies which arise as a consequence of excess collagen deposition during the wound healing process. The exact mechanism by which this occurs is not understood and currently no effective treatment exists. In this paper, we study the possible role of nitric oxide in excess scar formation. In recent years, the physiological role of th...

AIM To investigate the role of mast cells in surgical and pathological scar reactions by their identification and quantification using immunohistochemistry. METHODS Surgical scars and pathological scar reactions were stained immunohistochemically for tryptase to identify mast cells. These were quantified in the scar tissue and surrounding dermis. Statistical analyses were performed to test th...

Physiatrists play a critical role in managing the medical and functional consequences of serious burn injuries. Goals of rehabilitation include wound healing, scar prevention, hypertrophic scarring suppression, full range of motion, strengthening, and independent mobility and activities of daily living. This article is an overview of burn rehabilitation principles and patient management. The ul...

OBJECTIVES Volume is an important feature in the evaluation of hypertrophic scars and keloids. Three-dimensional (3D) stereophotogrammetry is a noninvasive technique for the measurement of scar volume. This study evaluated the reliability and validity of 3D stereophotogrammetry for measuring scar volume. STUDY DESIGN AND SETTING To evaluate reliability, 51 scars were photographed by two obser...

● Introduction ● What are hydrocolloid dressings? ● What are the main indications for hydrocolloid dressings? ● Are there any side effects of hydrocolloid dressings? ● How much fluid can hydrocolloid dressings absorb? ● What is the role of hydrocolloid dressings in maggot therapy? ● What is the role of hydrocolloids in hypertrophic scars and keloids? ● Have hydrocolloids been rendered obsolete ...

Keloid and hypertrophic scars are 2 types of excessive scarring observed clinically that require different therapeutic approaches. The clinical course and physical appearance define keloids and hypertrophic scars as separate entities; however, they are often confused because of an apparent lack of morphologic differences. Nevertheless, clinical differences between hypertrophic scars and keloids...

SUMMARY The development of cutaneous pathological scars, namely, hypertrophic scars (HSs) and keloids, involves complex pathways, and the exact mechanisms by which they are initiated, evolved, and regulated remain to be fully elucidated. The generally held concepts that keloids and HSs represent "aberrant wound healing" or that they are "characterized by hyalinized collagen bundles" have done l...

BACKGROUND AND OBJECTIVE The onset and progression of pathological scarring involves multiple cytokines and complex mechanisms. However, hyperplasia of fibroblasts and neovascularization plays important roles, which can be inhibited by paclitaxel. The aim of this study was to investigate the efficacy of paclitaxel in the treatment of hypertrophic scars on rabbit ears. METHODS Rabbit ear model...

BACKGROUND Silicone gel dressings decrease scar volume and soften hypertrophic tissue, allowing it to be more easily controlled by other methods. Although silicone does not appear to be an essential component of the treatment, nonsilicone dressings have been reported to cause no change in physical parameters during a 2-month treatment period. OBJECTIVE To compare silicone and nonsilicone gel ...
