The clinical value of lymph node immunohistochemistry was assessed in 343 consecutive patients with apparently node-negative breast cancer using antimucin monoclonal antibodies BC2, BC3 and 3E1.2. Occult metastases were detected in 41 patients (12 per cent). Although most of these were micrometastatic (< 2 mm in diameter), larger or diffuse deposits were(More)
Parathyroid hormone-related protein (PTHrP) has recently been identified in 60% of a series of primary breast cancers. The detection of a bone-resorbing factor in tumors with a propensity to metastasize to bone prompted study of PTHrP in breast cancer metastasis. PTHrP was localized by immunohistology in 12 of 13 (92%) breast cancer metastases in bone and(More)
OBJECTIVE To compare sacral nerve stimulation (SNS) with pudendal nerve stimulation (PNS) for interstitial cystitis (IC). PATIENTS AND METHODS Twenty-two patients with well-documented, refractory IC had a tined lead placed at S3 and a second electrode implanted at the pudendal nerve via a posterior approach. In a blinded, randomized design, each lead was(More)
A comprehensive epidemiological study of the involvement of cannabis and ethanol in motor vehicle fatalities in the Province of Ontario, Canada, is described. The study is based on toxicological analyses of blood and, when available, urine specimens. Ethanol was determined by headspace gas chromatography (GC). For cannabis, the methods employed were(More)
Androgen receptor assays have been performed on 1371 specimens of histologically confirmed primary and recurrent breast cancer. Forty-two patients who had received tamoxifen as treatment for advanced disease were assessed for objective response. Another 42 patients who had received chemotherapy were similarly studied. Patients with androgen(More)
Parathyroid hormone-related protein (PTHrP) is known to be a causative factor in humoral hypercalcemia of malignancy. A polyclonal rabbit antiserum directed against the amino-terminal region of the protein and immunoperoxidase methods have been used to locate the presence of PTHrP in a series of 102 consecutive invasive breast tumors removed surgically from(More)
In normal subjects the length of the functional anal sphincter has been compared with the extent of sensation to light touch in the anal canal. At rest, the sphincteric zone was the longer. On distension of the rectum, a decrease in pressure in the anal canal so shortened the functional sphincter that intrarectal pressure extended down to contact the(More)
