Multicenter Study
Treatment of metastatic spinal lesions with a navigational bipolar radiofrequency ablation device: a multicenter retrospective study.
Spinal metastatic lesions are a common occurrence among oncology patients and contribute to significant morbidity. Treatment options have been limited in their effectiveness and scope to this point. ⋯ The STAR System is an RFA device that was safely and effectively used in the treatment of spine metastatic osseous lesions. This new device allows RFA treatment of previously untreatable lesions with resultant reduction in pain that was not controlled by systemic or radiation therapy.

The increasing use of opioids to manage pain in the United States over the last decade has resulted in a subset of our population developing opioid tolerance. While the management of opioid tolerant patients during acute episodes of care is well known to be a challenge amongst health care providers, there is little in the literature that has studied opioid tolerance as a predictor of outcomes. We conducted a review on all admissions to Massachusetts General Hospital over a period of 6 months, from January 2013 to June 2013, and identified opioid tolerant patients at admission using the FDA definition of opioid tolerance. ⋯ This trend was found in the first 3 risk adjusted groups, but not in the fourth group where expected length of stay was greater than 10 days. The opioid tolerant population is at risk given the poorer outcomes and higher health care costs associated with their care. It is imperative that we identify opportunities for improvement and delineate specific pathways for the care of these patients.

In spite of the widespread performance of intra-articular zygapophyseal joint (IAZJ) injections, we know of no systematic analysis to date that examines the risks and types of adverse events when IAZJ injections are performed. ⋯ Fluoroscopically guided IAZJ injections have minimal adverse effects. The most common immediate adverse event was vasovagal reaction and most common delayed adverse event was injection site soreness.

Despite recent developments in implantable neurostimulation devices, the adjustment of stimulation levels to the patient's postural changes has remained a problem so far. ⋯ The findings of the present work are similar to those described in previous publications that showed the relationship between postural changes and several stimulation thresholds and pulse energy. The posture which requires lower energy - and whose corresponding therapeutic range (TR) is narrower--is supine decubitus.

Headache following head injuries has been reported for centuries. The majority of post-traumatic headache (PTH) patients will report resolution of their complaints within a few months from the time of the initial injury. PTHs can contribute to disability, lost productivity, and health care costs. ⋯ During 7 days of high cervical dorsal column electrical nerve stimulation trial, he reported almost 90% pain reduction and significant improvement on his quality of life. On 12 months follow-up after he underwent a permanent implant of high cervical dorsal column electrical nerve stimulation, he reported the same level of pain reduction along with 100% satisfaction rate. To the best of our knowledge, there have been no publications to date concerning the application of high cervical nerve stimulation for PTH.
