To review the teratogenic effects associated with the use of Food and Drug Administration-approved agents for bipolar disorder. ⋯ Well-characterized risks are associated with valproate, carbamazepine, lamotrigine, and lithium. The risks associated with psychotropic drug use need to be understood in the context of significant rates of relapse and associated morbidity when discontinuing bipolar treatment during pregnancy.

ReviewAn overview of HER-targeted therapy with lapatinib in breast cancer.
Breast cancer is a global public health burden with more than one million new diagnoses worldwide each year. As a significant proportion of women with early-stage breast cancer experience a relapse and metastatic breast cancer is generally incurable, therapeutic innovations are ongoing. One notable innovation in recent decades has been the identification of a subset of breast cancers that overexpress the transmembrane glycoprotein human epidermal growth factor receptor 2 (HER2) and the consequent development of HER2-targeted therapy. ⋯ Lapatinib, an orally available HER1- and HER2-targeted tyrosine kinase inhibitor, represents one such notable innovation. Lapatinib is currently being evaluated in both the adjuvant and metastatic settings and was recently approved by the United States Food and Drug Administration in combination with capecitabine, for the treatment of women with HER2-positive, pretreated, metastatic breast cancer. However, the ideal strategy for incorporating novel HER2-targeted agents, including lapatinib, into existing management paradigms is uncertain.

ReviewOptimal treatment of obstructive sleep apnea and excessive sleepiness.
Collapsibility of the upper airway in obstructive sleep apnea (OSA) causes repeated arousals from sleep, decreased oxygen saturation of the blood, and excessive sleepiness (ES). Patients with OSA are at increased risk of cardiovascular and cerebrovascular disease, and experience occupational and vehicular accidents more frequently than the general population. Furthermore, the life expectancy of patients with untreated OSA is significantly reduced. ⋯ There are a variety of treatments available for patients with OSA. Successful treatment involves encouraging patient compliance with CPAP or oral appliances. Primary-care physicians play a crucial role in recognizing this disorder and ensuring the best possible outcome through support and education.

Randomized Controlled Trial Multicenter StudyCost-effectiveness of transcranial magnetic stimulation in the treatment of major depression: a health economics analysis.
Transcranial magnetic stimulation (TMS) is a novel antidepressant therapy shown to be effective and safe in pharmacotherapy-resistant major depression. The incremental cost-effectiveness and the direct cost burden compared with sham treatment were estimated, and compared with the current standard of care. ⋯ TMS is a cost-effective treatment for patients who have failed to receive sufficient benefit from initial antidepressant pharmacotherapy. When used at earlier levels of treatment resistance, significant cost savings may be expected relative to the current standard of care.
