Q: Abstract: The records of 24 patients with malignant gliomas treated with carotid infusion of cisplatin and 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU) are reviewed for risk factors that might suggest the development of a permanent neurological deficit after infusion. Permanent neurological deficits were seen with doses of cisplatin as low as 69 mg/m2, although doses as high as 100 mg/m2 were tolerated by other patients. All 3 patients who developed permanent neurological deficits received fixed doses of cisplatin of 150 mg and supplied only 2 major intracranial branches from the infused carotid artery. In none of these patients was a filter used in the infusion line. Other risk factors identified in 2 of the 3 patients were diffuse neoplasm involving the region of the internal capsule and the use of an infusion pump rather than a pulsatile bolus infusion technique. The development of a permanent neurological deficit appeared unrelated to the dose of BCNU within the range utilized, and preinfusion administration of corticosteroids did not prevent neurological deficit. These possible risk factors should be considered in the future development of protocols for arterial infusion therapy of malignant gliomas.

Q: Abstract: The effect of surface electrode location on the estimates of the median frequency and conduction velocity of the myoelectric signal was investigated. The locations were identified with respect to the innervation zone and the tendonous portion of the tibialis anterior muscle. Considerable modifications in the median frequency and conduction velocity parameters were noted. The highest values of the median frequency occurred at the region of the innervation zone and tendonous insertion of the muscle, and decreased proportionally with distance from these areas. The rate of change of median frequency was not effected by electrode location. Estimates of conduction velocity were most stable in a region between the distal tendon and the adjacent innervation zone. This region also provided the best linear fit when comparing conduction velocity to median frequency estimates. The implications for signal detection procedures are discussed.

Q: Abstract: Twenty-nine consecutive patients with suspected primary hyperparathyroidism were examined preoperatively using ultrasound, sonographically guided fine needle aspiration, and aspirate immunostaining for PTH. In 25 patients, localization of enlarged parathyroid glands was successful. In 2 patients, the tumors were located retrosternally and, thus, could not be detected by ultrasound. One patient had a multinodular goiter which impeded localization. In 1 patient with renal osteodystrophy, 2 enlarged parathyroid glands in the neck were not visualized preoperatively. Cytology was not diagnostic, although some cytological features were suggestive of parathyroid cells. Immunostaining of the aspirated smears for PTH, however, correctly diagnosed all preoperatively localized lesions. Ultrasound should be the routine procedure of choice for preoperative localization of abnormal parathyroid glands in primary hyperparathyroidism. Fine needle aspiration and immunocytochemistry can supply confirmation, if necessary.

Parathyroid localization.
