Epidural gas occurring in benign disease is well documented. Gas formation within an epidural metastasis, which has not been previously reported, was demonstrated using computed myelography.
A transverse skin incision for anterior cervical spine surgery gives an excellent cosmetic result but is not extensile, thus accuracy of incision placement is essential. We describe a new, fast and inexpensive method of accurate transverse skin incision placement that does not rely on anatomical landmarks or intraoperative fluoroscopy. A ratio, determined… (More)

The intimate relationship of the internal carotid artery and its branches with the brain and cranial nerves, and the distribution of the internal carotid artery flow, make these aneurysms challenging, and potentially complicated in their surgical management.… (More)
We assessed the efficacy of a new thyroxine radioimmunoassay kit (Abott) in which polyethylene glycol is used to separate bound from free hormone. Mean serum thyroxine was 88 +/- 15 (+/-SD) microgram/liter for 96 normal persons. Results for hypothyroid and hyperthyroid persons were clearly separated from those for normal individuals. Women taking oral… (More)
