Treatment of cervical dystonia with Botox (onabotulinumtoxinA): Development, insights, and impact.
Cervical dystonia (CD), the most common focal dystonia encountered in neurologic practice, is a chronic disorder in which the muscles of the neck involuntarily contract and cause abnormal postures and movements of the head, neck, and shoulders. Treatment of CD prior to botulinum toxin was unsatisfactory, as existing therapies often did not improve symptoms. The use of botulinum toxin for CD grew out of its success in treating blepharospasm, another type of focal dystonia. ⋯ In addition, onabotulinumtoxinA treatment also reduced the complications of CD, as patients no longer develop contractures (permanent muscle and tendon shortening from prolonged untreated dystonia), which markedly limited the range of neck motion. The onset of onabotulinumtoxinA treatment also accompanied advances in understanding the functional anatomy of neck muscles, basal ganglia physiology, and video and other recording technology. Following the success of onabotulinumtoxinA in the treatment of CD, its use has been expanded into numerous other therapeutic indications, and these advances stimulated educational and training programs by various neurologic and other medical societies.

Regional wall motion abnormalities in critically ill patients with non-obstructed coronary arteries.
Left ventricular (LV) dysfunction is estimated to occur in 10%-25% of the general intensive care unit (ICU) population and is frequently seen as regional wall motion abnormalities (RWMAs). Although RWMA is mostly attributed to myocardial ischemia or infarction, some studies have suggested that nonischemic RWMA might also be prevalent. We sought to establish that RWMA can be seen in critically ill patients with normal coronary arteries and to explore reasons for RWMA in this population. ⋯ RWMA can be seen to occur in critically ill patients in the absence of coronary artery obstruction. Several conditions can cause regional hypokinesia, and cMRI is useful to evaluate the underlying etiology.

Secondary hemophagocytic lymphohistiocytosis (sHLH) is a syndrome characterized by an excessive systemic inflammatory response, manifested by multiple organ dysfunction, lacking reliable immune biomarkers for predicting their inflammatory status and prognosis. Soluble fms-like tyrosine kinase 1 (sFlt-1) is associated with various inflammation-related diseases, including sepsis and severe organ failure. ⋯ Retrospective analysis showed that sFlt-1 was a promising prognostic factor.

Pulmonary rehabilitation (PR) is a high-value intervention for persons with COPD and other chronic lung diseases. It is associated with improvement in exercise capacity, dyspnea, health-related quality of life, and depression as well as a reduction in hospitalization and improved survival when PR follows COPD-related hospitalizations. ⋯ Models, for example, virtual PR, may be an option for improving access but coverage in the United States by Medicare is tenuous. In addition, virtual PR models have considerable heterogeneity, which challenges uniform efficacy and selection of optimal candidates.
