The importance of HER2 status in breast cancer management has focused attention on the ability of clinical assays to correctly assign HER2 amplification status. There is no consensus as to the best method for assessing HER2 status. Disadvantages of fluorescence in situ hybridization (FISH) testing include longer time required for staining and scoring(More)
OBJECTIVES Cryosurgery represents a minimally invasive alternative for the management of small or equivocal lesions of the kidney. We evaluated the relationship between ultrasonographic appearance and intrarenal temperatures and the effect of renal artery occlusion on the efficacy of the freezing process in a canine model. METHODS Ten animals were treated(More)
PURPOSE The cause of the post-vasectomy pain syndrome is unclear. Some postulated etiologies include epididymal congestion, tender sperm granuloma and/or nerve entrapment at the vasectomy site. To our knowledge nerve proliferation has not been evaluated previously as a cause of pain. Vasectomy reversal is reportedly successful for relieving pain in some(More)
OBJECTIVES To examine the relationship between the width of the resection margin and disease progression in renal cell carcinoma (RCC) after nephron-sparing surgery (NSS). During NSS for RCC, it is standard practice to excise the tumor along with a surrounding margin of normal parenchyma (margin of resection) to ensure complete resection of the neoplasm.(More)
The demand for both reflexed and primary fluorescence in-situ hybridization (FISH) testing in the clinical setting is increasing. Relevant literature has reported the incidence of HER2 overexpression in 20% to 30% of cases, but some reports suggest that HER2 gene amplification rates are substantially lower. Published data, however, on primary FISH(More)
BACKGROUND Lesion composition, rather than size or volume, determines whether an atherosclerotic plaque will progress, regress, or rupture, but current techniques cannot provide precise quantitative information about lesion composition. We have developed a technique to assess the pathological state of human coronary artery samples by quantifying their(More)
BACKGROUND Acute rejection (AR) of the transplanted kidney has been identified as the major risk factor for the development of chronic rejection and immunological graft loss. However, the clinical presentation and response to AR therapy can vary considerably between recipients. METHODS We studied the first AR episode in 201 kidney-only recipients(More)
PURPOSE We investigated whether transplantation of single pediatric donor kidneys into adults leads to an increased incidence of functional allograft impairment and complications, as previously reported. MATERIALS AND METHODS To evaluate long-term functional outcome using single pediatric donor kidneys 60 adults (study group) who underwent transplantation(More)
The presence of HER2/neu gene amplification is prognostically and therapeutically significant for patients with breast cancer. We sought to determine whether a relationship exists between HER2/neu gene amplification and the histologic type and grade of tumor. The histologic features and corresponding HER2/neu amplification results of 401 cases of invasive(More)
