Azithromycin is a commonly prescribed macrolide antibiotic for the management of community-acquired pneumonia in the outpatient setting. Recent data have led to a growing concern of abnormal changes in cardiac electrophysiology and arrhythmias associated with its use. As azithromycin continues to be prescribed, clinicians should be aware of the new safety data and how it may affect concomitant medications or comorbid conditions in a patient. This article utilizes a case-based approach to assess azithromycin use and the risk of QT-prolongation and cardiac arrhythmias.

Characterize the prevalence and impact of crying and tearfulness as symptoms that may be suggestive of pseudobulbar affect (PBA) in residents of nursing facilities, including those with Alzheimer's disease (AD) and non-AD [non-AD-associated] associated dementia. ⋯ In the absence of an International Classification of Diseases 9th edition, Clinical Modification code, the presence of "crying, tearfulness" on MDS 2.0 item E1m was used as a proxy to identify potential PBA. Nursing facility residents with "crying, tearfulness" had a higher prevalence of all mood and behavior indicators as well as psychopharmacological medication use, compared with matched controls without "crying, tearfulness." Similar results were seen in the subgroup of residents with an underlying diagnosis of AD and/or non-AD dementia. Further research should validate the actual prevalence of PBA in this population, and the corresponding impact on resident outcomes.

New-onset urinary retention can typically be explained by the use of the routine normally suspected medications (e.g., anticholinergics, antihistamines). However, selective serotonin-reuptake inhibitors are not typically presumed as the cause of acute urinary retention (AUR). The following case describes the introduction of escitalopram in a patient and the subsequent development of AUR. ⋯ However, the retention persisted four days after suspending the ipratropium. Normal micturition resumed only after stopping the escitalopram without further need for catheterization. Escitalopram may cause rare cases of AUR and may often times be overlooked possibly because of the paucity of reporting.

With the prevalence of diabetes mellitus (DM) increasing, pathologic complications such as diabetic peripheral neuropathy (DPN) are also becoming more common. Of those diagnosed with DM, 10% to 20% of patients suffer from painful DPN. Until recently, only pregabalin and duloxetine possessed Food and Drug Administration (FDA) approval for this condition. ⋯ Tapentadol-ER is an opioid analgesic commonly used for the treatment of moderate-to-severe chronic pain that contains a unique dual mechanism acting as both a weak mu-opiod receptor agonist and norepinephine-reuptake inhibitor. It is by way of this unique dual mechanism that allows for effective analgesic effects with increased tolerability. This new FDA approval provides an additional therapeutic option to treat DPN in symptomatic patients.
