Repeat Trigeminal Nerve Radiosurgery for Refractory Cluster Headache Fails to Provide Long-Term Pain Relief

HEADACHE, Issue 2 2007
Shearwood McClelland III MD
Objective/Background.,Medically refractory cluster headache (MRCH) is a debilitating condition that has proven resistant to many modalities. Previous reports have indicated that radiosurgery for MRCH provides little long-term pain relief, with moderate/significant morbidity. However, there have been no reports of repeated radiosurgery in this patient population. We present our findings from the first reports of repeat radiosurgery for MRCH. Methods.,Two patients with MRCH underwent repeat gamma knife radiosurgery at our institution. Each fulfilled clinical criteria for treatment, including complete resistance to pharmacotherapy, pain primarily localized to the ophthalmic division of the trigeminal nerve, and psychological stability. Both patients previously received gamma knife radiosurgery (75 Gy) for MRCH with no morbidity, but no long-term improvement of pain relief (Patient 1 = 5 months, Patient 2 = 10 months) after treatment. For repeat radiosurgery, each patient received 75 Gy to the 100% isodose line delivered to the root entry zone of the trigeminal nerve, and was evaluated postretreatment. Pain relief was defined as: excellent (free of MRCH with minimal/no medications), good (50% reduction of MRCH severity/frequency with medications), fair (25% reduction), or poor (less than 25% reduction). Results.,Following repeat radiosurgery, long-term pain relief was poor in both patients. Neither patient sustained any immediate morbidity following radiosurgery. Patient 2 experienced right facial numbness 4 months postretreatment, while Patient 1 experienced no morbidity. Conclusion.,Repeat radiosurgery of the trigeminal nerve fails to provide long-term pain relief for MRCH. Given the reported failures of initial and repeat radiosurgery for MRCH, trigeminal nerve radiosurgery should not be offered for MRCH. [source]

Titration with Oxymorphone Extended Release to Achieve Effective Long-Term Pain Relief and Improve Tolerability in Opioid-Naive Patients with Moderate to Severe Pain

PAIN MEDICINE, Issue 7 2008
Richard Rauck MD
ABSTRACT Objective., Assess the effectiveness and tolerability of a program of gradual dose titration with oxymorphone extended release (ER) for treatment of moderate to severe chronic pain in opioid-naive patients. Design., Open-label, nonrandomized 6-month study with a titration/stabilization period of ,1 month followed by a 5-month maintenance period. Setting., Multidisciplinary pain centers in the United States. Patients., Adult opioid-naive patients with moderate to severe chronic pain. Interventions., Patients were gradually titrated from a 5-mg dose of oxymorphone ER (taken every 12 hours) to a stabilized dose that provided effective pain relief and was well tolerated. Outcome Measures., Brief Pain Inventory Short Form questions 5 and 9, patient and physician global assessments of pain relief, adverse events (AEs), and discontinuations. Results., The majority (94/126; 75%) of patients were stabilized on a dose of oxymorphone ER that provided effective pain relief with tolerable AEs. Most (81/94; 86%) required <24 days to reach a stable dose. Sixteen percent of patients in the titration period and 17% of patients in the maintenance period discontinued because of AEs possibly or probably related to oxymorphone ER. Patients completing the entire 5-month maintenance period experienced effective pain relief with significant (>50%) reductions of pain interference with quality-of-life measures. There was minimal dose escalation over the 5 months and low use of rescue medication. Conclusions., Oxymorphone ER provided effective pain relief from moderate to severe chronic pain in opioid-naive patients. Gradual titration was well tolerated, with a low rate of discontinuations caused by AEs. [source]

Long-Term Pain Relief in Patients with Cervicogenic Headaches after Pulsed Radiofrequency Application into the Lateral Atlantoaxial (C1-2) Joint Using an Anterolateral Approach

PAIN PRACTICE, Issue 4 2010
FIPP, Willy Halim MD
Abstract The lateral atlantoaxial joint has long been reported as a source of cervicogenic headache. We present a retrospective study, including 86 patients who had undergone lateral C1-2 joint pulsed radiofrequency application, for cervicogenic headache in a single pain center from March 2007 to December 2008. The percentage of patients who had ,50% pain relief at 2 months, 6 months, and 1 year were 50% (43/86), 50% (43/86), and 44.2% (38/86), respectively. Long-term pain relief at 6 months and 1 year were predicted reliably by ,50% pain relief at 2 months (P < 0.001). Apart from 1 patient that complained of increased severity of occipital headache lasting several hours, we had no other reported complications. [source]
