Myelopathy and polyneuropathy caused by nitrous oxide toxicity: a case report.

A 19-year-old man presented with a 1-month history of progressive 4-limb numbness and gait imbalance. Physical examination revealed mild general muscular weakness, areflexia, and wide-based, ataxic, steppage gait. Sensory tests showed diminished superficial sensation below the level of the cervical-thoracic junction and a glove-and-stocking pattern of sensory loss at the 4 extremities.

Liver transplantation is an alternative treatment of hepatocellular carcinoma beyond the Milan criteria.

Background: The decision to perform liver transplantation (LT) or liver resection (LR) for patients with hepatocellular carcinoma (HCC) who are beyond the Milan criteria remains controversial.

Methods: We retrospectively analyzed outcome data for 179 patients with HCC beyond the Milan criteria who were treated with LR (n = 135) or LT (n = 44). Univariate and multivariate Cox proportional hazard models were established.
