RESUMEN
A 21-year-old man presented to the emergency department with atypical chest pain, diaphoresis and shortness of breath. His electrocardiogram revealed ST segment elevation in leads II, III, aVF, V5 and V6, elevated creatine kinase-MB subunit levels and positive troponin I. He denied the use of cocaine, and smoking was his only risk factor for coronary artery disease. The patient was diagnosed with an acute myocardial infarction, yet an emergency coronary angiogram revealed normal coronary arteries. His medication history revealed recent commencement of bupropion for smoking cessation and pseudoephedrine as a nonprescription influenza remedy. It was postulated that this patient experienced acute coronary vasospasm in the presence of these two known sympathomimetic agents. The present case is the first report linking bupropion to an acute coronary syndrome, and one of a few cases associated with pseudoephedrine.

A new small caliber single-lumen balloon catheter has been devised specifically for retrograde ureterography. It is simple to use, does not traumatize the intramural ureter and provides excellent ureteral visualization.

Early recognition of catheter-associated urinary infection is essential to proper management. Daily bacteriological monitoring of indwelling catheters by routine urine culture is expensive and time consuming. A pilot study using liquid media at room temperature incubation showed a sensitivity approximating 90 percent in detecting bacteriuria. A simplified screening test can be carried out daily at the bedside; a positive screen would be followed by standard bacteriological studies. Such a method permits earlier diagnosis, and results in great saving in cost as well.

The infrequent association of reflux and kidney stone suggest the possibility that reflux may in some measure protect against stone formation. A simple animal experiment is proposed which should indicate whether this assumption is valid.
