摘要:

It is well established that multiple influences regulate cerebral blood flow: the overwhelming evidence continues to suggest that migraine is a disorder, albeit temporary, of cerebral hemodynamics. Thus, the classical theory of migraine is no longer tenable as viewed strictly and rigidly. Perhaps it would be easier to say that the migraine's aura is characterized by reduction in blood flow, often hemispheric, and that sometime during the headache phase cerebral hyperperfusion occurs. The process is under the control of multiple factors: neurogenic, chemical, metabolic, and myogenic. The blood flow changes do not necessarily correlate with the patient's symptoms. Thus, even now, migraine and other vascular headaches remain as descriptive diagnoses. The final pathology of migraine remains to be determined.

摘要:

The causes, diagnostic features, and therapy of chronic spinal arachnoiditis are reviewed. Two unexpected results from attempted epidural injections (one of lignocaine and clonidine, and one of lignocaine, clonidine, and morphine) in patients with this condition are described. The anatomical abnormalities of the epidural and subarachnoid spaces in such patients and the consequent unpredictable and potentially dangerous results that may follow drug injection into these spaces are discussed.

摘要:

Two acromegalic patients with severe headache, persisting after pituitary adenomectomy followed by radiotherapy in one, were treated with the somatostatin analogue SMS 201–995. Both had been resistant to conventional headache therapy and experienced dramatic and rapid relief after the first injection of the analogue. This result persisted with long-term treatment of the drug. Although the mechanism of action of SMS 201–995 in pain remains unclear, the rapid and efficacious analgesic effect of this compound may be one more indication for its use in pituitary tumors associated with cephalalgias.
