Observational Study
Computed Tomography-Guided Percutaneous Stylomastoid Foramen Puncture and Radiofrequency Thermocoagulation for Treatment of Hemifacial Spasm via Mandibular Angle Approach.
Hemifacial spasm (HFS) is characterized by progressive, paroxysmal, and involuntary convulsions on one side of the face. We have conducted in-depth exploration on the puncture approach through the mandibular angle, which is an important supplement to the first 2 approaches (i.e., premastoid approach and the postmastoid approach), especially for patients who cannot find a suitable way before and after the mastoid process. ⋯ Hemifacial spasm, radiofrequency thermocoagulation, stylomastoid foramen, CT-guided.

Low-dose ketamine infusion (LDKI) has shown effectiveness for treating acute pain associated with surgical and nonsurgical (traumatic, neuropathic, and acute cancer-related) origin as an adjuvant to opioids. The increasing use of LDKI as an opioid-sparing agent in multimodal analgesia requires a better understanding of its effects on the cardiovascular response, a known dose-dependent side effect of ketamine administration. We investigated the cardiovascular response of acute pain patients treated with LDKI. ⋯ Ketamine, adverse effects, tachycardia, hypertension, postoperative pain, chronic postsurgical pain.

Optimal intrathecal dosing regimens for hydromorphone are not well established for analgesia after abdominal surgery. ⋯ Drug-related side effects, opioid analgesics, outcome assessment, postoperative pain, spinal injections.
-
Responsiveness to opioid analgesics differs among patients with acute postoperative pain. ⋯ Single nucleotide polymorphism, postoperative pain, opioid, meta-analysis.

The benefit of intradiscal glucocorticoid injection (IGI) for discogenic low back pain (LBP) remains controversial. ⋯ Low back pain, lumbar back pain, intradiscal glucocorticoid injection, modic changes, meta-analysis.
