ReviewPain management in primary care: strategies to mitigate opioid misuse, abuse, and diversion.
Pain is among the most common reasons patients seek medical attention, and the care of patients with pain is a significant problem in the United States. Acute pain (mild-to-moderate intensity) represents one of the most frequent complaints encountered by primary care physicians (PCPs) and accounts for nearly half of patient visits. However, the overall quality of pain management remains unacceptable for millions of US patients with acute or chronic pain, and underrecognition and undertreatment of pain are of particular concern in primary care. ⋯ Safe and effective pain management requires clinical skill and knowledge of the principles of opioid treatment as well as the effective assessment of risks associated with opioid abuse, addiction, and diversion. Easily implementable patient selection and screening, with selective use of safeguards, can mitigate potential risks of opioids in the busy primary practice setting. Primary care physicians can become advocates for proper pain management and ensure that all patients with pain are treated appropriately.

ReviewRecent developments in the management of patients at risk for sudden cardiac death.
Sudden cardiac death (SCD) due to ventricular tachyarrhythmias is an important cause of mortality in the United States, 4% of which occurs in patients with structurally normal hearts. At least some arrhythmias are caused by ≥ 1 mutation in 1 of the genes that control electrical conduction through the heart by altering calcium homeostasis or depolarization or repolarization gradients in the ventricle. Although SCD may be the first presentation, patients may often present with symptoms of palpitations or hemodynamic compromise, such as dizziness, seizure, or syncope, particularly following exertion. ⋯ Quinidine and isoproterenol can be useful in treating Brugada syndrome. Left cervicothoracic stellectomy may occasionally be used in the treatment of long QT syndrome. As the genetic basis of these diseases becomes known, genetic testing is forming an increasingly important part of diagnosis, and gene-specific therapy is an area under investigation.

ReviewIloperidone, asenapine, and lurasidone: a brief overview of 3 new second-generation antipsychotics.
Three new second-generation antipsychotics were approved by the US Food and Drug Administration in 2009 and 2010: iloperidone, asenapine, and lurasidone. All 3 agents are approved for the treatment of acute schizophrenia in adults, and asenapine is also approved for the maintenance treatment of schizophrenia and as a monotherapy or as an adjunct to lithium or valproate for the treatment of bipolar manic or mixed episodes. The expectation is that these new agents will be less problematic regarding treatment-emergent weight gain and metabolic disturbances, which unfortunately can occur with several other second-generation antipsychotics. ⋯ They are the most common adverse events associated with asenapine treatment, and are clearly dose-related for lurasidone. In contrast, no therapeutic dose response for iloperidone, asenapine, or lurasidone is clearly evident from short-term clinical trials. Longer-term and naturalistic studies will be helpful in evaluating these agents and their role in the psychiatric armamentarium.
