Synthesis and degradation of collagen is an essential component of wound healing. In most persons, this deposition of collagen results in the formation of a fine line scar which restores much of the tensile strength to the injured tissue and is cosmetically acceptable. However, in certain individuals, the result of wound healing is the excessive accumulation of collagen, resulting in a hypertrophic scar or keloid. The precise origin of this abnormal collagen deposition is unknown, but recent studies have begun to identify potential mechanisms for these disfiguring and painful lesions. This article will review the clinical and laboratory findings pertinent to understanding the origin and treatment of excessive scarring.

Adult human hearts exhibit limited regenerative capacity. Post-injury cardiomyocyte (CM) loss can lead to myocardial dysfunction and failure. Although neonatal mammalian hearts can regenerate, the underlying molecular mechanisms remain elusive.

Introduction: Osteogenesis imperfecta is a rare inherited connective tissue disorder that results in excessive bone fragility due to defects in collagen production. The majority of osteogenesis imperfecta cases are inherited in an autosomal dominant pattern, and 17 genetic causes have been identified. Diagnosis is usually based on clinical presentation and low bone mineral density scores, while treatment involves a multidisciplinary approach using medical therapies such as bisphosphonates, vitamin C, and pamidronate.

Rationale: Gynecomastia, characterized by abnormal enlargement of male breast tissue, can lead to significant psychological distress, particularly among younger men. Traditional surgical options, such as subcutaneous mastectomy and liposuction, often result in visible scarring and contour deformities. This study introduces the "Stab Flatten" technique, a novel, minimally invasive approach for treating severe gynecomastia, designed to preserve chest aesthetics while minimizing postoperative complications, including scarring and contour irregularities.

Nasal adhesions, or synechiae, commonly occur following surgical procedures, resulting in nasal airway obstruction and patient discomfort. While various packing materials are available to prevent adhesion formation post-surgery, there is limited guidance on effectively dividing existing adhesions and determining the optimal packing materials to maintain separation afterward. We treated a 59-year-old man with severe adhesions in the anterior nasal cavity.

Background: Failed back surgery syndrome is a common problem faced by chronic pain management specialists. Steroid-only epidural injections have modest efficacy because of excessive scarring. Epidural hyaluronidase (HA), functions as a depolymerizing agent, successfully breaking down adhesions and collagen bundles, whereas dexmedetomidine (DEX) helps to reduce inflammation.
