BACKGROUND Case-control studies have successfully identified many genetic associations for complex diseases but suffer from lack of reproducibility in the same population. Demonstrating weak genetic effect requires large sample sizes to minimize statistical bias. Based on a study examining 500 myocardial infarction (MI) patients and 500 controls from the(More)
Thrombospondin-4 A387P Polymorphism With Myocardial Infarction To the Editor: A recently identified novel missense variant of TSP-4, A389P (29926 G C) was correlated with premature myocardial infarction (MI) by an exploratory genetic association study on 184 MI patients from the American population.1 In this study, the TSP-4 387P allele showed the strongest(More)
A variety of radiologic examinations are used to assess malignant tumors of the larynx. The primary role of radiographic examination is the pretreatment classification of laryngeal cancer, necessary to select the appropriate modality of treatment. The major radiologic modalities comprise conventional lateral radiography, anterior-posterior tomography,(More)
Radiological examinations are a prerequisite for accurate assessment of laryngeal tumors, especially when contemplating partial (voice conservation) surgery. The clinical assessments and preoperative radiographs from five cases have been compared with the histologic findings in whole organ serial sections of the laryngectomy specimens. These studies(More)
Radiologic investigation of possible salivary gland malignancy may answer in part questions concerning the lesion under study. Is it an invasive tumor, as evidenced by tissue destruction? Is the tumor intrinsic or extrinsic in origin to the salivary gland? Does the tumor extend into the deep portion of the salivary gland or beyond it into surrounding soft(More)
Since the late 1960's, metoclopramide has been used in Europe for the treatment of gastrointestinal motility disorders. It is less well known in North America and its application in diagnostic radiology is unfamiliar to most radiologists. By comparing a control group of 103 patients with a study group of 86 patients, we found that intramuscular injection of(More)
INTRODUCTION Platelet growth factors are known for their ability to speed up tissue healing (bone, skin, tendons, muscle). Various techniques make it possible to collect this platelet-rich plasma or PRP. METHODS This study compares the platelet concentrations obtained from five patients using GPS™ III, which has recently come onto the market, with those(More)
