BACKGROUND Thrombospondin is a high molecular weight adhesive glycoprotein that has been shown to function in mechanisms of tumor progression. The authors' previous studies have shown that thrombospondin promotes human lung carcinoma invasion by up-regulation of the plasminogen activator system through a mechanism involving the activation of transforming(More)
Tumor angiogenesis has recently been related to tumor growth and metastasis, which determine the clinical outcome of the patient. This study was designed to determine the relationship between angiogenesis in primary squamous cell carcinomas (SCC) of the head and neck and the development of recurrent or metastatic disease, or both. Different SCC of the head(More)
Infection following median sternotomy is a devastating and potentially life-threatening complication. The use of muscle flaps has become widely accepted as a mainstay in the treatment of these problems. We have previously described our successful use of a bipedicle muscle flap for reconstruction of sternal defects in 16 patients. In this paper, we describe(More)
Sternal wound infection with atypical mycobacteria following open heart surgery is a rare occurrence. Previous reports have described infection by Mycobacterium fortuitum, an acid-fast bacillus and member of a larger family of rapidly growing mycobacteria. The source and mode of transmission have not been identified. Surgical debridement and the combination(More)
Patients with malignant brain tumors requiring multiple craniotomies and external beam radiotherapy are at risk of scalp wound breakdown secondary to fibrosis and radiation damage. We present three cases to illustrate the nature of the problem and the surgical approaches to scalp repair. When a bicoronal incision has been used for the initial craniotomy,(More)
Radiation-related ulcers of the chest wall provide a great challenge to reconstructive surgeons because of the necessity of protecting the underlying vital structures and the difficulty in repairing irradiated tissues. To evaluate the efficacy of treatment, 24 patients who underwent reconstruction of radiation related ulcers of the chest wall were(More)
Substituted dextran polymers have been shown to bind growth factors and protect them from enzymatic degradation. Using this information, other researchers have been able to use these substituted dextrans to enhance the healing of bone in an environment where bone would otherwise not regenerate. We used substituted dextran polymers to evaluate their ability(More)
The defect resulting from partial or complete maxillectomy can often be reconstructed with a skin graft and a prosthesis. In situations where this simple maneuver is unsatisfactory, a more complex reconstructive modality, providing the restoration of composite tissue, is required. The scapular microvascular-free flap was used in this series of 11 patients,(More)
BACKGROUND Thrombospondin-1 (TSP-1) is a matrix-bound adhesive glycoprotein. Breast carcinoma cells exhibit increased expression of a novel TSP-1 receptor. We evaluated the role of this receptor in breast cancer adhesion and progression. METHODS Adhesion assays were performed to evaluate MDA-MB-231 breast cancer cell adhesion to TSP-1 in vitro in the(More)
