A cost analysis of two- versus three-instrument robotic-assisted inguinal hernia repair with mesh: time is money.

Equipment expenses and operating times can lead to higher costs with robotic surgery. We compared the cost-effectiveness of 2- vs. 3-instrument (2i vs.

Severe myeloneuropathy from acute high-dose nitrous oxide (N2O) abuse.

Background: Myeloneuropathy from chronic exposure to nitrous oxide has been described. Nitrous oxide irreversibly alters B(12) activation, causing signs and symptoms of B(12) deficiency.

Objectives: We describe a case of myeloneuropathy secondary to acute use of high-dose nitrous oxide.
