Abdominal Pain:As many as half of patients who are evaluated for abdominal pain do not receive a precise diagnosis. And for about half of those who are given a diagnosis, the diagnosis is wrong. In this article, I will use actual cases (not "textbook" examples) to illustrate an approach to abdominal pain that begins with a careful differential diagnosis. I also offer some general guidelines for evaluating patients.

Using Passive Measures to Improve Patient Medication AdherenceAdherence is a complex behavioral process strongly influenced by environmental factors. Six posters designed to improve medication adherence were displayed in a medical clinic, with each poster displayed for 1 month. These posters were seen by clinic patients but, as passive measures, required no additional time on the part of clinicians. Medication adherence to antidepressant therapy was assessed for two 18-month periods. Days of therapy and median gap (the number of days a patient goes without medication before filling the next prescription) were similar between the periods. Medication possession ratio (MPR) was increased in the intervention period (0.974 vs 0.994 days). During the 6-month period that the adherence posters were displayed, persistence decreased by only 10% (versus 22% for the nonintervention period). Use of passive measures may improve patient medication adherence. In this prospective study, both the MPR and persistence were improved. (Drug Benefit Trends. 2008:20:17-24)

What Is Causing This Patient’s Acute Left-Sided Weakness?A 56-year-old woman with type 2 diabetes mellitus and hypertension presented with acute left-sided weakness and altered mental status, for which she was hospitalized. The patient, who was obese, was in her usual state of well-being until 2 months before this presentation, when she noted a gradual onset of generalized weakness. She received a diagnosis of severe hypokalemia that was refractory to oral potassium supplementation. The outpatient workup of the cause of her hypokalemia was in progress.

Drug Therapy in Elderly Patients:ABSTRACT: Age-related changes that affect drug distribution, such as increased total body fat, decreased muscle mass, and decreased total body water, necessitate reduction in the dosage of water- and lipid-soluble agents. Because creatinine clearance declines with age, the dosage of agents that are excreted primarily by the kidney must also be lowered to prevent toxicity. Examples include aminoglycosides, fluoroquinolones, penicillins, procainamide, lithium, angiotensin-converting enzyme inhibitors, and digoxin. A good rule of thumb to follow until creatinine clearance can be calculated is to reduce the total dose by half in frail elderly persons or in those with established renal disease. Anticholinergic agents should be used with caution because they are associated with urinary retention, heart block, constipation, dry mouth, blurred vision, sedation, and acute or chronic confusion in elderly patients.
