To compare the incidence of pain relief following injection of local anesthetic (LA) into lumbar discs that caused concordant pain during provocation testing. ⋯ If the criterion standard to confirm painful annular tears is concordant pain provocation and 80% or greater pain relief following LA injected into lumbar discs, the SAAD, ADPD, and FAD protocols show statistically similar 20% to 30% prevelance.

To better understand the association of depression with pain treatment utilization in a multiple sclerosis (MS) population. ⋯ The results demonstrate that depression is not associated with higher pain treatment utilization. These findings support the assertion in previous studies that the mechanism by which depression impacts medical utilization is through increased appointments for nonspecific complaints, not for specific medical problems. While this suggests that treating depression may not be helpful in reducing pain treatment utilization specifically, it remains important to treat depression to reduce pain-related suffering and medical utilization more broadly.

We sought an optimal medial branch block (MBB) cutoff value for both single and double MBB protocols that would best correlate with a positive outcome of medial branch neurotomy (MBN). ⋯ The double MBB protocol better correlated with favorable MBN outcomes compared with a single MBB protocol. Using a double MBB protocol, a 70% cutoff value for reported subjective pain relief post-MBB best predicted overall outcome following MBN. Without a confirmatory MBB, an 80% cutoff value was the optimal value.

To determine the differences in pain, disability, depression, and pressure sensitivity between men and women with fibromyalgia syndrome (FMS), and to analyze the relationship between pain and pressure sensitivity in FMS. ⋯ Women with FMS showed higher pain severity and lower PPT than men, whereas men exhibited longer duration of symptoms and disability. In men with FMS, the intensity of ongoing pain was positively correlated to pressure hyperalgesia over the neck. This study suggests that FMS could show a different phenotype in women and men and confirm that women exhibit lower PPT than men.
