PURPOSE To evaluate the effect of thymidylate synthase (TYMS) and methylenetetrahydrofolate reductase (MTHFR) genotypes on toxicity in patients treated with capecitabine for advanced colorectal cancer and to determine the effect of these polymorphisms on the pretreatment levels of serum folate and plasma homocysteine. EXPERIMENTAL DESIGN Fifty-four(More)
OBJECTIVE To test the hypothesis that implementation of a practice guideline for blood gas measurement would decrease numbers and increase appropriateness of tests (according to criteria in the guideline) for up to 1 yr after introduction of the guideline. DESIGN Numbers of tests and appropriateness of each test were measured retrospectively during each(More)
Monocular Estimate Method (MEM) dynamic retinoscopy is an objective clinical method for determining the accommodative response to a fixed accommodative stimulus. Although MEM has been used in many clinical investigations, it has never been compared with the measurement of accommodative response by the haploscope. This report compares the accommodative(More)
Stress thallium-201 scanning proved to be a highly sensitive and specific screening procedure for myocardial ischemia in 52 consecutive cases with coronary arteriograms. Stress thallium-201 scanning was considerably more accurate and more specific than the exercise electrocardiogram (ECG) as evidenced by a sensitivity of 83% compared to 55%, and a(More)
A patient with fully expressed, sporadic ectrodactyly, ectodermal dysplasia, and cleft lip and/or palate (EEC) syndrome with renal involvement is presented; descriptions of four similar patients were found in the literature. Based on these patients, we suggest that the renal involvement is a form of dysplasia secondary to fetal urinary tract obstruction. We(More)
BACKGROUND AND OBJECTIVE Our previous study showed that protease inhibitors were attenuated by the periodontal pathogen Porphyromonas gingivalis in cultured gingival epithelial cells. We hypothesize that fewer protease inhibitors would be present in more advanced periodontal disease sites, where the level of P. gingivalis may be high. The goal of this study(More)
