Herpes zoster causes acute pain and sometimes leads to postherpetic neuralgia (PHN). The previously reported risk factors of PHN such as old age, allodynia, paresthesia and so on are not based on evidence. Although nerve block is useful to relieve acute pain and recommended for prevention of PHN, evidence is scanty. ⋯ Old age, hypesthesia and delayed nerve blocks were the risk factors of PHN. Nerve blocks in the early phase of herpes zoster may be useful to prevent PHN, particularly in the younger patients.

Induced hypotensive anesthesia is a well established technique in adult patients. We examined retrospectively the effect of sodium nitroprusside pediatric patients undergoing pelvic osteotomy with simultaneous femoral osteotomy. ⋯ These results suggest that sodium nitroprusside is a safe and effective drug for induced hypotension in pediatric patients.
