For patients with lumbosacral contiguous double-level disc herniation, there has been no consensus on which level(s) should be treated. Selective nerve root block (SNRB) can identify the pain-generating nerve root; however, its diagnostic accuracy remains controversial due to potential spread of the injectate. Sequential SNRB from S1 to L5 may improve the diagnostic specificity. ⋯ Sequential SNRB from S1 to L5 was an effective approach to guide PELD treatment for patients with lumbosacral contiguous double-level disc herniation. Health care providers may consider using this approach to facilitate future clinical practice.

Recurrent LDH (rLDH) is one of the most common causes of unsatisfactory outcomes after discectomy, which usually needs secondary surgery and leads to physical and psychological suffering for patients and substantial costs for society. ⋯ This study demonstrated that the recurrence rate of LDH at 5-year follow-up was 6.27% and there was a significant statistical relationship between FO, DHI, and Modic changes and early rLDH. Surgeons should take FO angles, DHI, and Modic change into consideration before surgery to achieve a satisfactory postoperative outcome and a relatively lower early recurrence rate. More patients and further investigation should be taken to assess the risk factors for early rLDH.

Radiofrequency thermocoagulation (RFT) of the trigeminal ganglion is an excellent treatment option for medically intractable trigeminal neuralgia. However, this procedure can manifest abrupt changes in cardiovascular responses. With abrupt cardiovascular changes, a sudden trigeminocardiac reflex can occur during RFT of the trigeminal ganglion. ⋯ FO puncturing, electrical stimulation, and thermal heating demonstrated an abrupt increase in heart rate and mean arterial pressure. The incidence of sudden bradycardia during RFT of the trigeminal ganglion was 25%. Most cases of bradycardia were observed during FO puncturing.

Randomized Controlled Trial Comparative Study
Comparison of Pain Reduction and Changes in Serum Cortisol and Glucose Levels to Different Doses of Lumbar Epidural Dexamethasone: A Prospective Study.
Lumbar epidural steroid injection (LESI) is an effective treatment for low back pain. However, it may result in increased blood glucose levels, decreased plasma cortisol concentrations, and suppression of the adrenocorticotropic hormone axis. ⋯ After the first lumbar epidural injection of either 4 mg or 8 mg of dexamethasone, there was a reduction in pain in both groups. There was no significant difference in serum cortisol and glucose levels before treatment and during follow-up. Therefore, 4 mg or 8 mg of dexamethasone can be considered a treatment for patients who have low back pain.
