One hundred and three colorectal carcinoma specimens were examined to determine the value of the xylene and alcohol fat clearance technique in detecting lymph node metastases. The mesocolon or mesorectum was dissected initially by the traditional method and all the lymph nodes identified were examined histologically. After fat clearance the specimen was(More)
Telepathology is the practice of pathology at a distance by using video imaging and telecommunications. Significant progress has been made in telepathology. To date, 12 classes of telepathology systems have been engineered. Rapid and ultrarapid virtual slide processors may further expand the range of telepathology applications. Next-generation digital(More)
PURPOSE The aim of our study was to determine the five-year survival of patients with colorectal carcinoma whose Dukes classification had changed following fat clearance of the mesocolon or mesorectum. METHODS One hundred three patients with colorectal carcinoma were followed up at a special clinic for at least five years after surgery. The tumors from(More)
This paper describes the design and fabrication of a novel array microscope for the first ultrarapid virtual slide processor (DMetrix DX-40 digital slide scanner). The array microscope optics consists of a stack of three 80-element 10 x 8-lenslet arrays, constituting a "lenslet array ensemble." The lenslet array ensemble is positioned over a glass slide.(More)
Nitric oxide is produced by several isoenzymes which are present in many different tissues. We have recently reported the presence of inducible nitric oxide synthase in a breast cancer cell line. The purpose of this study was to examine the distribution of endothelial nitric oxide synthase (eNOS) in a series of human breast tumours. Immunohistochemical(More)
A number of studies in developed countries have reported variation in the frequency of Epstein-Barr virus (EBV)-associated Hodgkin's disease (HD) with age. A 'three disease' model for HD that incorporates the EBV association, histological subtype of HD and age has recently been proposed. In this model, Hodgkin's disease of childhood and older adults is(More)
The cross-sectional area of diaphragmatic muscle fibres was measured using a Quantimet 720 image analysis system in 18 patients with emphysema and six control non-emphysematous patients. The technique proved to be an accurate method of measuring muscle fibre area and much more rapid than the previously described methods. The mean cross-sectional area of the(More)
Virtual slide telepathology is an important potential tool for providing re-review of surgical pathology cases as part of a quality assurance program. The University of Arizona pathology faculty has implemented a quality assurance program between 2 university hospitals located 6 miles apart. The flagship hospital, University Medical Center (UMC), in Tucson,(More)
PURPOSE Malignant pleural mesothelioma (MPM) expresses high levels of epidermal growth factor receptor (EGFR), and preclinical studies have identified antitumor activity of EGFR tyrosine kinase inhibitors (TKIs) in MPM. We conducted a phase II trial of the EGFR TKI erlotinib in previously untreated patients with MPM. PATIENTS AND METHODS Patients with(More)
