Even though the prevalence of thoracic pain has been reported to be 13% of the general population and up to 22% of the population in interventional pain management settings, the role of thoracic discs as a cause of chronic thoracic and extrathoracic pain has not been well studied. The intervertebral discs, zygapophysial or facet joints, and other structures including the costovertebral and costotransverse joints have been identified as a source of thoracic pain. ⋯ Based on the available evidence for this systematic review, due to limited evidence, thoracic provocation discography is rarely recommended for the diagnosis of discogenic pain in the thoracic spine, if conservative management has failed and facet joint pain has been excluded.

Chronic persistent neck pain with or without upper extremity pain is common in the general adult population with a prevalence of 48% for women and 38% for men, with persistent complaints in 22% of women and 16% of men. Multiple modalities of treatment are exploding in managing chronic neck pain along with increasing prevalence. However, there is a paucity of evidence for all modalities of treatments in managing chronic neck pain. Controlled studies have supported the existence of cervical facet or zygapophysial joint pain in 36% to 60% in heterogenous population of these patients. However, these studies also have shown false-positive results in 27% to 63% of patients with a single diagnostic block. ⋯ Diagnostic cervical facet joint nerve blocks are safe, valid, and reliable. The strength of evidence for diagnostic facet joint nerve blocks is good with the utilization of controlled diagnostic blocks with at least 75% pain relief as the criterion standard; however, the evidence is limited for single blocks or dual blocks for relief of 50% to 74% and single blocks with at least 75% pain relief.

Review
Systematic review of the therapeutic effectiveness of cervical facet joint interventions: an update.
The prevalence of chronic, recurrent neck pain is approximately 15% of the adult general population. Controlled studies have supported the existence of cervical facet or zygapophysial joint pain in 36% to 67% of these patients, when disc herniation, radiculitis, and discogenic are not pathognomic. However, these studies also have shown false-positive results in 27% to 63% of the patients with a single diagnostic block. There is also a paucity of literature investigating therapeutic interventions of cervical facet joint pain. ⋯ The indicated evidence for cervical radiofrequency neurotomy is fair. The indicated evidence for cervical medial branch blocks is fair. The indicated evidence for cervical intraarticular injections with local anesthetic and steroids is limited.

The role of antithrombotic therapy is well known for its primary and secondary prevention of cardiovascular disease by decreasing the incidence of acute cerebral, cardiovascular, peripheral vascular, and other thrombotic events. The overwhelming data show that the risk of thrombotic events is significantly higher than that of bleeding during surgery after antiplatelet drug discontinuation. It has been assumed that discontinuing antiplatelet therapy prior to performing interventional pain management techniques is a common practice, even though doing so may potentially increase the risk of acute cerebral and cardiovascular events. There are no data available concerning these events, specifically in relation to the occurrence of thromboembolic events, even though some data are available concerning bleeding complications. Even then, interventionalists seem to routinely discontinue all antithrombotic therapy prior to all interventional pain management techniques. ⋯ The results illustrate an overwhelming pattern of discontinuing antiplatelet and warfarin therapy as well as aspirin and other NSAIDs prior to performing interventional pain management techniques. However, thromboembolism complications may be 3 times more prevalent than epidural hematomas (162 versus 55 events). It is concluded that clinicians must balance the risks of thromboembolism and bleeding in each patient prior to the routine discontinuation of antiplatelet therapy.

Randomized Controlled Trial
The effect of Helicobacter pylori eradication on migraine: a randomized, double blind, controlled trial.
Recent studies have shown a positive correlation between Helicobacter pylori (H. pylori)infection and migraine headache. ⋯ H. pylori eradication may have a beneficial role on migraine headache. This shows the significance of H. pylori treatment in the management of migraine headache among Iranian patients.
