Case Reports
Intrathecal morphine overdose during combined spinal-epidural block for Caesarean delivery.
We describe a 25 mg intrathecal morphine overdose during a combined spinal-epidural block for a Caesarean delivery. Naloxone infusion (5.24 mg over 24 h) was started prior to the patient becoming symptomatic and almost immediately after the overdose. Invasive therapeutics such as mechanical ventilation were avoided.

Randomized Controlled Trial Clinical Trial
Efficacy of intravenous magnesium in neuropathic pain.
Postherpetic neuralgia is a complication of acute herpes zoster characterized by severe pain and paraesthesia in the skin area affected by the initial infection. There is evidence that the N-methyl-D-aspartate receptor is involved in the development of hypersensitivity states and it is known that magnesium blocks the N-methyl-D-aspartate receptor. ⋯ The present study supports the concept that the N-methyl-D-aspartate receptor is involved in the control of postherpetic neuralgia.
