We have noted in breast biopsies performed for microcalcifications a spectrum of lesions in the terminal duct lobular unit (TDLU) characterized by columnar epithelial cells with prominent apical cytoplasmic snouts, intraluminal secretions, and varying degrees of nuclear atypia and architectural complexity. The appearance of some of these lesions is(More)
In Schizosaccharomyces pombe, the endonuclease Uve1 functions as the first step in an alternate UV photo-product repair pathway that is distinct from nucleotide excision repair (NER). Based upon the broad substrate specificity of Uve1 in vitro, and the observation that Uve1 mutants accumulate spontaneous mutations at an elevated rate in vivo, we and others(More)
OBJECTIVE To determine the application of a probabilistic/categorical approach for reporting breast fine needle aspiration (FNA) and its dependence on the cytopathologist's level of experience. STUDY DESIGN All breast surgical specimens that had preoperative breast FNA at our institution during a 3-year period were identified. The cytologic results were(More)
Although the cytologic features of papillary carcinoma of the thyroid are well-known, none is entirely specific. We conducted this study to determine the minimal criteria necessary to achieve 100% specificity for the diagnosis of papillary carcinoma on fine-needle aspiration (FNA). Forty patients with histologically confirmed papillary carcinoma and 17(More)
Hepatic microvesicular fat (MVF) has been associated with clinical syndromes of liver failure (such as acute fatty liver of pregnancy and Reye's syndrome). We performed this pilot study to investigate the specificity and potential risk factors of MVF. Sections of the liver from 17 adult autopsies were snap-frozen, and Oil Red O (ORO)-stained sections were(More)
BACKGROUND The standards of the American Association of Blood Banks describe a minimum hemoglobin level of 12.5 g per dL for apheresis donors. Until 1995, the authors' institution accepted occasional platelet donors with a lower minimum hemoglobin (11.5 g/dL), if accompanied by medical director approval. STUDY DESIGN All donation records from a 6-month(More)
BACKGROUND The presence of tumor cells in peritoneal washing cytology specimens taken during surgery affects the staging of many gynecologic malignancies. Peritoneal washings are often collected routinely, even in cases of presumed benign disease. This study was designed to address whether evaluation of these specimens is justified. METHODS We reviewed(More)
BACKGROUND Thrombotic thrombocytopenic purpura (TTP) is a rare, potentially fatal disease of uncertain etiology. Early diagnosis and treatment are essential to patient survival. The ]purpose of this report is to describe three patients with levonorgestrel implants (Norplant system) who developed TTP. CASES A 24-year-old woman with levonorgestrel implants(More)
