Single coronary artery with probable origin of the anomalous right coronary artery from a left atrial recurrent branch.

A 62-year-old woman presented for evaluation of chest pain. She ruled out for myocardial infarction, and subsequent non-invasive studies were diagnostic for ischemia. On coronary angiography, she was found to have a previously undescribed variant of single coronary artery, in which the anomalous right coronary artery probably arose from a left atrial recurrent branch. In this patient, the congenital anomaly was an incidental finding, since her clinical presentation was felt to be due to moderate obstructive disease of the left anterior descending artery, in the setting of poorly controlled systemic hypertension.

Effects of theophylline on exercise indices in a patient with chronotropic incompetence.

Several investigators have documented the successful use of oral sustained-release theophylline in treating symptomatic bradycardia and sick sinus syndrome. This paper reports a case of chronotropic incompetence in which specific exercise indices, including the chronotropic response index, were used to measure the therapeutic efficacy of theophylline.

Hunger strikes: preventing harm to students.

When the health center encountered a student hunger strike, an initial search for medical information regarding fasting provided very little on which to build management decisions. The result of a more thorough evaluation of starvation literature is presented, along with survey responses from students who fasted. Starvation may produce many adverse events, including death. Yet, according to reports, acaloric fasts that include full water intake seem to be readily tolerated for 2 weeks in young, healthy adults. Our students included juice, sports drinks, and vitamins in their diets and completed their strike without major problems. Supplementation with carbohydrates and vitamins may improve the safety or comfort of a hunger striker, but clear proof of this effect does not exist.

Screening and chemoprophylaxis for tuberculosis infection in college populations.

Active tuberculosis and the potential for widespread disease exist on college campuses. To maximize the benefit and minimize the potential harm of a screening program, health service clinicians should administer tuberculin skin tests to high-risk students only. Those found to be infected should be considered for prophylactic treatment. The criteria that identify students as being at high risk need to be clearly appreciated, especially the issue of birth outside the United States. Certain countries of origin pose a high risk; others do not. By understanding the fundamentals of the current pandemic and employing a consistent approach, college health professionals can make the correct screening decisions, thereby reducing the risk to their campus communities and assisting in the eradication of this preventable disease.
