To correlate MR and CT discography findings with pain response at provocative discography in patients with discogenic back pain. ⋯ Typical MR findings with concordant pain at discography include grade 4 or 5 disc degeneration and presence of a high intensity zone. Typical CT discography findings with concordant pain were fissured/ruptured discs and contrast extending into/beyond the outer annulus on CT.

Comparative Study
Centralization: its prognostic value in patients with referred symptoms and sciatica.
Prospective, comparative cohort study. ⋯ Patients with sciatica and suspected disc herniation who have a centralization response to a mechanical evaluation will have significantly better outcomes. Patients who do not have centralization will be 6 times more likely to undergo surgery.

The analgesic effect of long-acting opioids, such as transdermal fentanyl, has been demonstrated in patients with cancer, neuropathic pain and chronic low back pain (CLBP). However, the broader effect of long-acting opioids on the patient's health-related quality of life (HRQoL) is less well known. ⋯ CLBP patients who chronically used short-acting opioids showed tremendous HRQoL burden. Favorable HRQoL outcomes were observed among patients who reported pain relief.
