INTRODUCTION Necrotizing fasciitis is an uncommon infectious entity that poses difficult diagnostic and therapeutic management decisions. PURPOSE This paper addresses the presentation, evaluation and management of the patient with a necrotizing soft tissue infection. CASE REPORT A 54-year-old man presented to his physician with pain and swelling of the(More)
Facial allotransplantation is a clinical reality, proposed to provide improved functional and aesthetic outcomes to conventional methods of facial reconstruction. Multidisciplinary efforts are needed in addressing not just the surgical and immunological issues but the psychological and sociological aspects as well. In view of this, an international survey(More)
Early recognition of vascular compromise within microvascular free-tissue transfers is essential if reexploration is to prove successful. Tissue oxygen tension is increasingly recognized to be a sensitive and reliable index of tissue perfusion, and preliminary studies suggest that it may be of value in the assessment of free-flap viability. We describe our(More)
Microvascular surgery has emerged as an attractive area for recent advances in the field of gene therapy. The present study investigated the survival of ischemic, experimental skin flaps after treatment with the gene encoding vascular endothelial growth factor (VEGF). In 30 Sprague-Dawley rats, anterior abdominal skin flaps supplied by the epigastric artery(More)
Due to the complex, and often tenuous nature of microsurgical tissue transfer, postoperative monitoring of free tissue flaps plays a vital role in the management of such patients. Some of the more challenging reconstructive problems occur in patients with lower extremity trauma, yet to date, no preferred protocol exists for the postoperative care of lower(More)
The authors investigated the optimal period of maturation following the creation of arteriovenous (AV) loops using polyterafluoroethylene (PTFE) in a white rat model, which were subsequently used to support free-tissue transfer The AV loops in Group 1 (n = 17) were allowed to mature for 3 days prior to creation of the flap, while those from Group 2 (n = 14)(More)
"Longitudinal melanonychia" refers to a brown or brown-black longitudinal band on a fingernail or toenail. A number of conditions can cause longitudinal melanonychia, but its main importance is that, in some patients, it may indicate the presence of a subungual malignant melanoma. Hyperpigmented nail bands are not uncommon in African-American, Latino and(More)
The authors describe a rat flap model that is useful for flow studies. It is an epigastric flow-through flap that mimics the clinical use of a radial artery flow-through (RAFT) flap that has been used as an adjunct to a distal lower extremity arterial bypass graft to improve patency when there is potential high outflow resistance. The hypotheses were that(More)
To assess the effect of perioperative factors on the incidence of postoperative wound complications, the authors retrospectively analyzed 101 patients who had undergone modified radical mastectomy. These factors included age, body weight, operative techniques, estimated blood loss, wound-catheter drainage, extent of axillary dissection, nodal involvement,(More)
