Randomized Controlled TrialManagement of chronic postoperative groin pain.
Postoperative groin pain is a common complaint following surgery of the abdomen and groin. Although this pain usually resolves in the early postoperative period, some experience prolonged, debilitating pain lasting months to years. There is currently a lack of consensus as to the appropriate transition from medical to surgical management of these patients. ⋯ Average preoperative and postoperative pain was 7.6 and 1.2, respectively, a statistically significant reduction. This study confirms high success rates for patients surgically treated for chronic postoperative groin pain when proper selection criteria and appropriate surgical techniques are applied. A management approach is proposed and the surgical technique is described for treatment of these patients.

ReviewA critical evaluation of the use of Biobrane as a biologic skin substitute: a versatile tool for the plastic and reconstructive surgeon.
Biobrane and Biobrane-L are becoming increasingly popular in the management of superficial and moderate-depth partial-thickness burns, particularly in pediatric patients. When used appropriately, they have been shown to reduce pain levels, healing time, inpatient stay, and nursing requirements when compared with traditional dressings. In this manuscript, we provide a critical evaluation of the evidence base for the varied uses of Biobrane within the field of plastic and reconstructive surgery. ⋯ Biobrane is a versatile biosynthetic wound dressing. There is good evidence (Grade A) to support the use of Biobrane in the management of burns, particularly in partial-thickness burns in children. Biobrane also has many potential uses as a dressing outside the burns unit of which we feel reconstructive surgeons should be aware. Conditions resulting in disruption of the epidermis such as toxic epidermal necrolysis (TEN) and paraneoplastic pemphigus have been managed successfully using Biobrane (Grade B). Biobrane has also been successfully used following dermabrasion, skin-graft harvesting, and laser resurfacing (Grades B to C). Temporary coverage with Biobrane has been successfully used in individuals with chronic wounds such as open sternotomy sites and venous ulcers (Grades B to C). Biobrane has a wealth of potential uses outside its traditional remit; however, further prospective clinical trials are warranted if these new applications are to become more widely accepted.

Effect of heparin on production of transforming growth factor (TGF)-beta1 and TGF-beta1 mRNA expression by human normal skin and hyperplastic scar fibroblasts.
Heparin affects both dermal fibroblast proliferation and collagen and may mediate these effects by altering the levels of transforming growth factor-beta1 (TGF-beta1) production and TGF-beta1 mRNA expression as a wound healing modulator. The purpose of this study is to probe the effect of heparin on TGF-beta1 and TGF-beta1 mRNA production by human normal skin and hyperplastic scar fibroblasts. This research investigates the effect of heparin on TGF-beta1 and TGF-beta1 mRNA production by human normal skin and hyperplastic scar fibroblasts with exposure to 0 microg/mL, 100 microg/mL, 300 microg/mL, or 600 microg/mL heparin for 24, 48, 72, or 96 hours in a serum-free in vitro model. ⋯ Heparin (300 microg/mL and 600 microg/mL) stimulated TGF-beta1 production by normal skin (26% to 83%) and hyperplastic scar fibroblasts (63% to 85%), with statistical significance (P < 0.05) at various time points. Heparin (300 microg/mL and 600 microg/mL) also stimulated TGF-beta1 mRNA expression by normal skin (12% to 53%) and hyperplastic scar fibroblasts (33% to 52%), with statistical significance (P < 0.05) at various time points. These effects of heparin on normal skin and hyperplastic scar fibroblasts may have implications for hyperplastic scar formation and wound healing in vivo.
