Glossopharyngeal neuralgia/neuropathy is rare, and less than 3% of cases involve cardiac arrhythmias of syncope due to activated vagal reflex pathways. Most of these cases are successfully treated with medical management with or without pacemaker placement. We present the first reported case of glossopharyngeal neuralgia/neuropathy with cardiac symptoms refractory to medical management including pacemaker placement but successfully treated with Gamma Knife Radiosurgery. ⋯ To our knowledge, we present the first case of glossopharyngeal neuralgia/neuropathy with medically refractory cardiac dysfunction successfully treated with Gamma Knife Radiosurgery. We advocate that Gamma Knife be considered for similar subsets of patients.

Randomized Controlled Trial
Ketamine and Magnesium for Refractory Neuropathic Pain.
Ketamine is often used for the management of refractory chronic pain. There is, however, a paucity of trials exploring its analgesic effect several weeks after intravenous administration or in association with magnesium. The authors hypothesized that ketamine in neuropathic pain may provide pain relief and cognitive-emotional benefit versus placebo and that a combination with magnesium may have an additive effect for 5 weeks. ⋯ The results of this trial in neuropathic pain refuted the hypothesis that ketamine provided pain relief at 5 weeks and cognitive-emotional benefit versus placebo and that a combination with magnesium had any additional analgesic effect.

We aimed to compare interlaminar epidural steroid injections (ILESI) and bilateral transforaminal epidural steroid injections (TFESI) on pain intensity, functional status, depression, walking distance, and the neuropathic component in patients with lumbar central spinal stenosis (LCSS). ⋯ Both ILESI and TFESI are reliable treatment options for LCSS. ILESI might be preferred because of easier application and more effectiveness. However, TFESI might be a better option in patients with more prominent neuropathic pain.

Evaluating the effectiveness of stellate ganglion blockades (SGBs) proves challenging, since the criteria defining a successful blockade are controversial. This may be one reason for the scarcity of studies on this topic, thus forcing clinical guidelines to remain conservative in recommending SGBs. Moreover, factors to predict which patients will benefit from blockade series are not yet available. ⋯ Data indicate that us-SGBs are safe and effective in reducing sympathetically maintained pain in patients with CRPS and neuropathic pain syndromes. Pain reduction after the first blockade may predict total pain reduction after a blockade series. Other clinical measures seem unsuitable to predict effectiveness.

Spinal cord stimulation (SCS), a minimally invasive treatment option for long-term neuropathic pain, has been shown to be effective in patients with persisting neuropathic pain after spine surgery. However, little is known about the long-term cost and quality-of-life (QoL) patterns in SCS-treated patients. The aim is to describe the use of SCS, costs, pre-spine-surgery and post-spine-surgery QoL, and reported pain intensity, in patients who have undergone spine surgery and subsequent SCS implantation. The results will be related to outcome and cost in spine surgery patients in general. ⋯ In spine surgery patients, mean QoL and pain intensity levels improved following surgery. Patients subsequently treated with SCS had lower reported QoL and higher costs before the initial spine surgery, and spine surgery did not lead to any substantial improvements, however, costs decreased following SCS implantation in these patients.
