We studied the effects of a silicone gel bandage that was worn for at least 12 hours daily on the resolution of hypertrophic burn scar. In a second cohort, the prevention of hypertrophic scar formation in fresh surgical incisions by this bandage was also evaluated. In 19 patients with hypertrophic burn scars, elasticity of the scars was quantitated serially(More)
A prospective, controlled clinical trial was designed to assess the efficacy of a new treatment of hypertrophic scars. Silicone gel sheeting was applied to 14 hypertrophic scars in 10 adults for 8 weeks. The treated scars and untreated, mirror-image or adjacent control scars were photographed, biopsy specimens were taken, and they were measured(More)
Human adipose-derived mesenchymal stem cells (MSCs) were differentiated into chondrogenic MSCs, and fibrin glue was used together to explore the feasibility of whether cartilages can be generated in vivo by injecting the differentiated cells. Mesenchymal stem cells extracted from human adipose were differentiated into chondrogenic MSCs, and such(More)
To study the effects of alteration of blood flow on wound healing in rabbit ear ulcers, two models were designed that produced maximum ischemia and maximum congestion, respectively, with complete survival of the ear by selective division of one or more of three arteries or veins and circumferential incisions. After selection of the best models from six(More)
OBJECTIVE To describe the clinical and imaging characteristics of Polyimplant Prosthesis (PIP) hydrogel breast implants. METHODS Seven patients with surgically confirmed 8 ruptured and 6 normal PIP hydrogel implants were enrolled in our study. We reviewed retrospectively the medical records and breast ultrasonographic and magnetic resonance imaging (MRI)(More)
Recent studies have shown that liposuction aspirates from rat, rabbit, mouse, and human sources contain pluripotent adipose tissue-derived stromal cells (ASCs) that can differentiate into various mesodermal cell types, including osteoblasts, myoblasts, chondroblasts, and preadipocytes. To develop a research model for autologous bone tissue engineering, we(More)
Recently proposed procedures for in vitro generation of new cartilage may be difficult to perform in humans because so many chondrocytes are needed for tissue engineering. In this study the authors investigated new, efficient, low-cost techniques for the isolation and culture of chondrocytes from the ear cartilage of the rabbit. They performed a low-density(More)
Historically, tissue expansion is a prolonged process, typically requiring at least 6 weeks to complete. Recently, interest has increased in shortening this time period. In the current study, a continuous infusion device maintaining constant expander pressure less than capillary filling pressure was used in a canine model in seven dogs to minimize the time(More)
Seven consecutive patients from 1986 through 1989 for 8 extensive recurrent and/or irradiated skin cancers of the face and scalp are retrospectively evaluated. One patient was treated by conventional surgical margins, and the limitations of this method in sampling margins are compared to the Mohs' micrographic surgery (MMS) used for the other 6 patients.(More)
BACKGROUND Among thin patients, upper pole skin of less than 2 cm on a pinch test is an indication for submuscular implant placement. However, rippling, palpability, and visibility of the implant are frequently observed in the lower and lateral aspects of the breast due to the lack of muscle coverage in the area. To overcome these problems, a(More)
