Noninvasive Cardiac Stress Testing:
January 1st 2003Cardiac stress imaging has become increasingly sophisticated; nevertheless, standard exercise electrocardiography can provide valuable clinical information, such as time to onset of angina or ST-segment depression, maximal heart rate and blood pressure response, and total exercise duration. Pharmacologic stress agents may be substituted for patients who cannot exercise on a treadmill; however, these agents must be used in conjunction with echocardiography or nuclear scintigraphy to obtain adequate diagnostic information.

Travel Risks: Update on Traveler's Diarrhea and Other Common Problems
December 1st 2002ABSTRACT: Patients can greatly reduce the risk of traveler's diarrhea by drinking only bottled water and eating only hot foods prepared in sanitary conditions or peelable fruits and vegetables. Antibiotic prophylaxis for traveler's diarrhea is no longer routinely recommended; reserve it for patients who may have to consume food and beverages of questionable safety, those with reduced immunity, and those likely to experience serious consequences of illness. Adequate hydration is the first step in treating traveler's diarrhea. Drug therapy-loperamide or fluoroquinolones in adults and bismuth subsalicylate or azithromycin in children-can ameliorate symptoms and speed recovery. Recommend that patients who are prone to motion sickness take an antiemetic/antivertigo agent before symptoms begin. Acetazolamide can be used both to prevent and to treat altitude sickness. Contraindications to air travel include a resting oxygen saturation of less than 90%, pregnancy of more than 36 weeks' duration, pneumothorax, recent myocardial infarction or chest or abdominal surgery, active infectious diseases, and poorly controlled seizures or sickle cell anemia.
Thyroid Disease in the Elderly:
November 1st 2002ABSTRACT: Age-related anatomic and physiologic alterations in the thyroid gland have a variety of clinically important effects. Hypothyroidism, which is common in older persons, raises cholesterol and triglyceride levels; hyperthyroidism may be masked by the severity of the cardiac problems it causes. In younger persons, depression may accompany hypothyroidism but not hyperthyroidism; however, in the elderly, it may be a feature of either condition. Papillary carcinoma-the most common type of thyroid cancer-is more aggressive in older persons. All these factors necessitate a cautious and deliberate approach to the management of thyroid disorders in elderly patients.
Therapy for Stable CAD:Is the Pill as Mighty as the Balloon?

Exercise for Patients with Osteoarthritis: A Phased Approach to Plannng
September 15th 2002ABSTRACT: Exercise can be an effective way to stabilize or slow the degenerative process of osteoarthritis-provided convenient, safe, and enjoyable activities are selected and achievable goals are set. Implement an osteoarthritis exercise plan in phases, and progress gradually from one phase to the next; this will help both you and your patient anticipate difficulties and gauge progress. The first phase-the initial evaluation-includes gathering baseline data, targeting an area of the body to focus on first, and identifying potential contraindications to activities. Subsequent phases include range of motion exercises (stretching), isometric and isotonic strengthening exercises, and recreational or functional activities. Encourage patients to continue stretching exercises throughout the program.
