Review Case Reports
Restless legs syndrome induced by escitalopram: case report and review of the literature.
Restless legs syndrome (RLS) is a sensorimotor disorder characterized by distressing sensations deep inside the limbs, typically occurring at bedtime or rest. These paresthesias involve an irresistible urge to move the limb, which provides temporary relief but at the expense of sleep and quality of life. The pathophysiology of RLS has been related to dopaminergic pathway dysfunction, thereby aligning it closely with depression from both pathophysiologic and treatment perspectives. ⋯ Using the Naranjo adverse drug reaction probability scale, which assesses the probability of a drug causing an adverse event, the patient's score was 9, indicating a definite adverse drug reaction. Although published case reports have linked fluoxetine, sertraline, citalopram, paroxetine, and mirtazapine to RLS, this is the first report, to our knowledge, of escitalopram as a cause of RLS. Based on this case and additional data published with other SSRIs and SNRIs, we believe that escitalopram should be added to the list of agents that can induce RLS.

The Institute of Medicine has identified adverse drug events as factors that significantly contribute to increased patient morbidity and mortality. As critically ill patients receive numerous drugs to treat a multitude of complicated health problems, they are at high risk for adverse drug events. ⋯ Whether this adverse drug event is preventable is unclear, but recommendations have been proposed to minimize the potential for development of this syndrome. Research is under way to collect data on the use of propofol in intensive care units and on its prevalence.

Health care providers prescribe skeletal muscle relaxants for a variety of indications. However, the comparative efficacy of these drugs is not well known. Skeletal muscle relaxants consist of both antispasticity and antispasmodic agents, a distinction prescribers often overlook. ⋯ Much of the evidence from clinical trials regarding skeletal muscle relaxants is limited because of poor methodologic design, insensitive assessment methods, and small numbers of patients. Although trial results seem to support the use of these agents for their respective indications, efficacy data from comparator trials did not particularly favor one skeletal muscle relaxant over another. Therefore, the choice of a skeletal muscle relaxant should be based on its adverse-effect profile, tolerability, and cost.

To assess the effects of a waiting period after clopidogrel treatment before coronary artery bypass grafting (CABG). Design. Single-center, prospective, observational study. ⋯ A strategy to delay CABG after clopidogrel treatment led to reduced blood product administration. The optimal waiting period after clopidogrel treatment is not known but appears to be at least 5 days before CABG.
