Randomized Controlled Trial
Glial Attenuation With Ibudilast in the Treatment of Medication Overuse Headache: A Double-Blind, Randomized, Placebo-Controlled Pilot Trial of Efficacy and Safety.
Medication overuse headache (MOH) is a condition bordering between a chronic pain condition and a substance dependence disorder. Activation of immunocompetent glial cells in the central nervous system has been linked to both pathological pain and drug addiction/reward. Preclinically, ibudilast attenuates glial activation and is able to reduce neuropathic pain and markers of substance dependence. We therefore hypothesized ibudilast would reduce headache burden and opioid analgesic requirements in patients with opioid overuse headache. ⋯ Using the current dosing regimen, ibudilast does not improve headache or reduce opioid use in patients with MOH without mandated opioid withdrawal. However, it would be of interest to determine in future trials if ibudilast is able to improve ease of withdrawal during a forced opioid down-titration when incorporated into an MOH detoxification program.

To educate physicians about appropriate acute migraine treatment guidelines by determining (1) where headache patients were first prescribed opioids and barbiturates, and (2) the characteristics of the patient population who had been prescribed opioids and barbiturates. ⋯ Approximately 20% of patients presenting to a headache center reported current use of opioids and/or barbiturates. ED physicians were reported to be the most frequent first prescribers of opioids and general neurologists were the most frequent first prescribers of barbiturates. Taken as a whole, these data provide a useful snapshot of the wide variety of physician specialties that might benefit from additional education on the appropriate use of opioids and barbiturate-containing medications in patients with headaches.

Case Reports
External Nasal Neuralgia: A Neuropathic Pain Within the Territory of the External Nasal Nerve.
Nasal pain is a challenging diagnosis and very little has been reported in the neurological literature. The nose is a sophisticated structure regarding its innervation, which is supplied by the first and second divisions of the trigeminal nerve. Painful cranial neuropathies are an important group in the differential diagnosis, although they have been described only scarcely. Here, we report a case that can conform a non-traumatic external nasal nerve neuralgia. ⋯ External nasal neuralgia seems a specific neuralgia causing nasal pain. Anesthetic blockades of the external nasal nerve may be a valid treatment for this condition.
