Thorough irrigation of contaminated or infected traumatic and open surgical wounds is considered standard practice. High-power pulse lavage is frequently used to facilitate the removal of surface contaminants and bacteria but studies to compare the results of various irrigation techniques are limited. The purpose of this randomized, controlled clinical(More)
BACKGROUND Local anaesthetic agents in combination with epinephrine are frequently used in local reconstructive procedures such as skin tumour excision and local flap closure. The purpose of this study was to measure the effect of subdermal injection of lidocaine combined with epinephrine on cutaneous blood flow in the forearm and in the face. METHODS(More)
BACKGROUND Soft tissue and bony tumors of the pelvis are rare, but when they occur, treatment presents both an oncologic surgical and a reconstructive challenge. After reconstruction, soft tissue defects can be large and there is usually exposed bone and/or joint. A retroperitoneal abdominal wall defect may also be present. Flap mobilization is generally(More)
BACKGROUND Ischemia is a limiting factor during distraction osteogenesis. The authors sought to determine the extent of ischemia in the distraction zone and whether endothelial progenitor cells home to the distraction zone and participate in local vasculogenesis. METHODS Laser Doppler imaging was used to assess the extent of blood flow in the distraction(More)
Our aging population has presented us with many new challenges. One such challenge is the need to manage an increase in wound-related problems effectively and efficiently. Over time, two parallel, yet divergent, management systems have developed. One strategy, used by medical specialists, uses a variety of dressings, topical enzymes, and local and systemic(More)
Replantation of amputated digits remains one of the most challenging areas in plastic and reconstructive surgery. Complicated cases of digital amputation, such as fingertip amputations, multidigital amputations, and so forth, pose an even greater challenge, requiring extraordinary solutions for successful replantation. The authors present their experience(More)
BACKGROUND Cranial vault remodeling procedures are carried out for both syndromic and nonsyndromic craniosynostosis as well as to correct some acquired deformities of the cranial vault. These procedures improve not only cosmesis but also neurological symptoms. The purpose of this study was to determine the incidence of "late" cephalohematoma, an(More)
Numerous flaps exist for coverage of injuries to the upper extremity, ranging from local, to regional, to free tissue transfer. The choice of flap is dependent on a variety of factors, including patient, functional needs, and depth of injury. The paraumbilical perforator (PUP) flap for upper extremity coverage can offer the benefits and versatility of(More)
A 57-year-old woman presented with a predominantly right-sided cellulitic area of her buttock after receiving multiple bilateral silicone injections in the buttocks. The workup revealed subcutaneous infection with rapidly growing mycobacteria. Surgical management and etiologic factors are discussed, and a review of the literature is presented.
