Randomized Controlled Trial
Dexamethasone Effectively Reduces the Incidence of Post-neurotomy Neuropathic Pain: A Randomized Controlled Pilot Study.
Radiofrequency neurotomy (RFN) of facet or sacroiliac joints is widely used for the treatment of chronic axial pain and can provide long-term pain relief in well-selected patients. The most common side effect is transient neuropathic pain at the paravertebral level of interest. Pain physicians commonly administer corticosteroid post-neurotomy to reduce the risk of post-neurotomy neuropathic pain, yet it remains unclear if this provides a true reduction in incidence. ⋯ A statistically significant reduction in post-neurotomy pain was observed in the steroid group. This protocol can be feasibly conducted in an effective and resource-efficient manner. Additional research is needed to increase the power of the study.

Ultrasound guided nerve blocks have become a popular tool in the armamentarium for pain physicians because of its advantages over fluoroscopy by offering portable, radiation-free and real-time imaging. But ultrasound guided procedures require training and practice to gain the expertise. There is a scarcity of review articles describing ultrasound guided injections techniques for nerve blocks of the head and neck. ⋯ Ultrasound guided nerve blocks of the head and neck are useful techniques for pain physicians to learn.

At present, there is no ideal method for the treatment of trigeminal neuralgia (TN). The need for an easy, safe, non- or micro-neurodestructive, repeatable treatment, with a fairly satisfactory rate of pain relief, is paramount. Pulsed radiofrequency (PRF) as a minimally invasive and microdestructive technique has been reported to be an option for TN; however, no study has reported the long-term outcome of TN in a large case series. ⋯ The results of this study show the promising long-term effect of PRF on primary TN. The safety and repeatability might be more easily accepted by patients with TN and should be considered a preferred treatment option before choosing neurodestructive or more invasive methods.

The leakage of cerebrospinal fluid (CSF) can be encountered spontaneously or after procedures such as epidural or spinal anesthesia, intrathecal chemotherapy, CSF tapping, or other various spinal procedures. The leakage of CSF can lead to intracranial hypotension, which is associated with an orthostatic headache. For such patients with this type of headache, an epidural blood patch is the treatment of choice. ⋯ Most patients in the PDPH group required a single epidural blood patch to achieve complete recovery from headache. However, patients in the SIH group required repeated epidural blood patches for complete pain relief.
