Coronary spasm is an important and often overlooked etiology of chest pain. Although coronary spasm, or Prinzmetal's angina, has been thought of as benign, contemporary studies have shown serious associated adverse outcomes, including acute coronary syndrome, arrhythmia, and death. Definitive diagnosis of coronary spasm can at times be difficult, given the transience of symptoms. Numerous agent...

Accepted I September 1994 Abstract Objectives-To validate a provocative chelation test with 2,3-dimercaptosuccinic acid (DMSA) by direct comparison with the standard ethylene diamine tetraacetic acid (EDTA) test in the same subjects; and to compare and contrast the predictors of lead excretion after DMSA with those after EDTA. A metal chelating agent given orally, DMSA may mobilise and enhance ...

While rare compared to female breast cancer the incidence of male breast cancer (MBC) has increased in the last few decades. Without comprehensive epidemiological studies, the explanation for the increased incidence of MBC can only be speculated. Nevertheless, one of the most worrying global public health issues is the exponential rise in the number of overweight and obese people, especially in...

Despite the tremendous progress that scientists have made throughout the history of cancer research, there are still far too many deaths and remaining scientific questions for us to be content with our current knowledge of the disease. The eighth Origins of Cancer symposium, held July 21, 2017 at Van Andel Research Institute, was organized around the theme of “Tackling Provocative Questions” to...

The outflow changes in 26 eyes were measured during the course of a positive provocative test with pilocarpine and phenylephrine. Three separate patterns of response occurred: (1) One dose of pilocarpine and phenylephrine produced an acute attack with a large reduction in outflow. (2) The first dose of pilocarpine and phenylephrine produced a fall in pressure and increase in outflow. The second...
