I describe the results of retrogasserian differential lidocaine block to aid in the selection of patients for a differential thermal lesion in the trigeminal ganglion and rootlets. This procedure temporarily duplicates the state of analgesia without anesthesia one seeks to make permanent with the radiofrequency heating. The results of this heating procedure are described in the treatment of 71 patients with facial pain of cancer, postherpetic, periodic migrainous neuralgia, acromegaly, trigeminal neuropathy, central pain, post-traumatic facial neuralgia, and atypical facial neuralgia.

Somatostatin analogue (Sandostatin; SMS 201-995) is utilized as a therapy in acromegaly because of its efficiency in inhibiting GH secretion; it induces some clinical improvements, such as headache remission in acromegalic patient, which seem to be unrelated to Gh normalization. We have examined 8 acromegalic patients, suffering from headache, after injection of saline solution and subsequently of SMS 201-995 (100 y), in order to study the mechanism of analgesic effect induced by Sandostatin administration. Headache, by autovaluation test, heart rate frequency, PAO, sistolic and diastolic blood velocity in medial cerebral artery, by utilizing Transcranial Doppler Sonography (SDSV), have been measured before and after saline and after SMS 201-995. GH and beta-endorphin have been also assayed in plasma samples. All patients have shown a rapid and complete improvement in headache after Sandostatin administration. At the same time we have observed an increase in SDSV and a parallel slight increase in PAO values, more evident in the diastolic phase. Plasma beta-endorphin assay has shown rather conflicting results after SMS 201-995 administration. Our results confirm an important and rapid analgesis effect of Sandostatin on acromegaly headache unrelated to GH normalization. The cerebral emodinamic changes suggest their involvement in Sandostatin induced analgesia.

This paper reports the phenomenon of dependence to a somatostatin octapeptide analog used for the treatment of acromegaly and severe headache. The mechanism of this dependence is still unknown, but could be based on the interaction of the somatostatin analog with opioid receptors. Analgesia may be at least partially supported by the opioid modulation of pain transmission, but also by general "appetitive" behavioral activation due to the effect of somatostatin on its receptors.
