Comparative StudyEffects of mannitol and steroid therapy on intracranial volume-pressure relationships in patients.
The intracranial volume-pressure response was measured in 61 patients undergoing continous monitoring of intraventicular pressure. This test, which determlnes the increase in intracranial pressure induced by an addition of 1 ml in ventricular CSF volume in 1 sencond, yields information concerning spatial compensation in patients with intracranial space-occupying processes. ⋯ In patients with intracranial hypertension, intravenous mannitol (0.5gm/kg) and intramuscular betamethasone (26 mg) both reduce the volume-pressure response significantly more than they reduce intracranial pressure. This suggests that these agents favorably alter the configuration of the volume-pressure curve.

Radiofrequency percutaneous Gasserian ganglion lesions. Results in 140 patients with trigeminal pain.
Percutaneous radiofrequency ablation of the Gasserian ganglion or posterior root, or both, was performed in 140 patients. Of the 135 patients with trigeminal neuralgia, satisfactory analgesia was achieved in 121. ⋯ The phenomenon of facial blush may be helpful in avoiding unwanted first-division analgesia. In four of five patients with other forms of neuralgia, the procedure did not relieve pain; the fifth patient experienced significant relief from pain due to carcinoma of the mandible.
