CONTEXT Accurate quantitation of bone marrow plasma cells is an important component in the diagnosis and posttreatment assessment of plasma cell dyscrasias. Although flow cytometry is sometimes used for this purpose and can rapidly evaluate many cells, the accuracy of flow-based plasma cell quantitation compared with morphologic assessment (currently the gold standard) is uncertain as direct co...
OBJECTIVES Identification of tumor-specific somatic mutations has had a significant impact on both disease diagnosis and therapy selection. The ability of next-generation sequencing (NGS) to provide a quantitative assessment of mutant allele burden, in numerous target genes in a single assay, provides a significant advantage over conventional qualitative genotyping platforms. METHODS We asses...
Introduction Magnetic Resonance Imaging (MRI) has emerged as a promising noninvasive imaging modality for the serial assessment of vessel wall thickness in the carotid artery as an early marker of atherosclerosis. For clinical application of this technique, Scan-Rescan reproducibility is paramount. Currently, a multicontrast protocol, including a combination of MR-weightings is used as referenc...

OBJECTIVE To evaluate the outcome of phototherapeutic keratectomy (PTK) treatment of epithelial basement membrane dystrophy (EBMD) patients and to examine clinical and morphologic signs of recurrent dystrophy. DESIGN Cross-sectional, clinic-based study. PARTICIPANTS Fifty-two eyes of 39 patients diagnosed with EBMD who underwent PTK between 2001 and 2008. METHODS Preoperative symptoms, be...
Since Hansen first noted variations in the morphology of leprosy bacilli in 1895, many investigators have given attention to such morphologic variations as revealed by staIned preparations. After the advent of antileprosy drugs, many clinicians observed rapid decrease in the proportion of uniformly stained bacilli under therapy. In 1960 Ridley first proposed a "Granularity Index" based on three...
Millions of patients worldwide are hospitalized each year due to an acute coronary syndrome (ACS). Patients who have had an acute coronary syndrome are at higher risk for developing future adverse cardiovascular events such as cardiovascular death, congestive heart failure, or a repeat ACS. Currently, there have been several electrocardiographic metrics used to assess the risk of ACS patients f...
