Treatment of Postherpetic Neuralgia With Intravenous Administration of Zinc Sulfate: A Case Report.
Gabapentinoids (gabapentin and pregabalin) are first-line drugs for postherpetic neuralgia (PHN), but some PHN patients have inadequate therapeutic response. Zinc deficiency has been identified as a risk factor for PHN. ⋯ The aforementioned findings provide a molecular pain-relieving basis for zinc supplements as an add-on therapy to pregabalin. We report 2 zinc-deficient PHN patients who received zinc sulfate intravenously as an add-on therapy to pregabalin and responded well.

Case Reports
A Subarachnoid Hemorrhage Presenting as Massive Nasopharyngeal Bleeding: A Case Report.
Patients who present with a subarachnoid hemorrhage may have more than 1 intracranial aneurysm at risk, which may not be appreciated until a subsequent aneurysmal bleeding event occurs. We describe a patient who underwent successful aneurysmal clipping, but later presented urgently with large-volume epistaxis 48 hours after the procedure. After successful intubation of the patient, subsequent angiographic imaging determined that the massive intranasal/oral hemorrhage was due to bleeding through the former operative site, from rupture of a previously unrecognized aneurysm. This series of events demonstrates the importance of selecting the most at-risk aneurysm for surgical intervention.

Case Reports
Axillary Artery Dissection After Ultrasound-Guided Infraclavicular Brachial Plexus Block: A Case Report.
A 52-year-old man with end-stage renal disease underwent ultrasound-guided infraclavicular brachial plexus block for revision of an arteriovenous fistula. On postoperative day 2, the patient developed pain and loss of motor function in the surgical extremity. ⋯ Sensory deficits resolved over the next 3 days. Smoking, hypertension, diabetes mellitus, and chronic intake of a calcineurin inhibitor might have predisposed the patient to iatrogenic arterial dissection.
