Lynch syndrome is one of the most common autosomal dominantly inherited cancer syndromes. Mutations in MLH1, MSH2, MSH6, and PMS2 account for greater than 98% of reported mutations in Lynch syndrome families. It has been reported that large genomic deletions in MLH1 and MSH2 are a frequent cause of Lynch syndrome in certain populations. Using a multimodal(More)
Excessive extracellular matrix deposition that occurs in many fibrotic skin disorders such as hypertrophic scarring and scleroderma is often associated with hypoxia. CD109 is a novel TGF-β co-receptor and TGF-β antagonist shown to inhibit TGF-β-induced extracellular matrix protein production in vitro. We examined whether CD109 is able to regulate(More)
BACKGROUND With an increasing life expectancy and more active elderly population, management of geriatric trauma patients continues to evolve. The aim was to describe the mechanism and injuries of severely injured geriatric patients and to identify risk factors associated with mortality. METHODS The Trauma Registry at a Canadian Level I trauma center was(More)
BACKGROUND The complement system is composed of bactericidal and hemolytic proteins that increase capillary leakage and inflammatory cell migration. The role of complement C3 to augment wound healing has not yet been studied. METHODS We examined the effects of topical complement C3 formulation at two concentrations (10 and 100 nM) on the rat surgical skin(More)
BACKGROUND Topical application of collagen has been suggested to enhance wound healing; however, its long-term effect on wounds has not been studied in a rat model. HYPOTHESIS Topical application of collagen type I will not facilitate incision healing or cosmesis in rats up to 28 days postwounding. METHODS The effects of bovine collagen type I (6 mg/mL)(More)
BACKGROUND Delayed-healing traumatic, surgical, and chronic wounds can be detrimental to patients and the health care system. The authors set out to investigate the effects of complement C5, a naturally occurring chemotactic cytokine, on wounds. METHODS The authors examined the effects of complement C5 on the rat paired skin incision model. Each rat(More)
Background. Complements C3 and C5 have independently been shown to augment and increase wound healing and strength. Our goal was to investigate the combinatorial effect of complements C3 and C5 on wound healing. Methods. Each rat served as its own control where topical collagen was applied to one incision and 100 nM of C3 and C5 in collagen vehicle was(More)
Hypoplastic breast anomalies remain a reconstructive challenge. In this article, the authors review the spectrum of nonsyndromic breast hypoplasia in the adolescent girl, namely idiopathic breast hypoplasia and tuberous breast deformity. Challenges specific to this population include (1) identifying the ideal timing for surgery, (2) choosing the optimal(More)
There is scant literature regarding a recently identified clinical entity termed red breast syndrome. Its clinical presentation has been described as a non-infectious, self-limited erythema of a post-mastectomy breast reconstructed using acellular dermal matrix. Its incidence, risk factors, pathophysiology, clinical course, management, and long-term(More)
BACKGROUND Surgical site infections (SSIs) result in significant patient morbidity following immediate tissue expander breast reconstruction (ITEBR). This study determined a single institution's 30-day SSI rate and benchmarked it against that among national institutions participating in the American College of Surgeons National Surgical Quality Improvement(More)
