The history, present organization, and future plans of the pain clinic at the University Hospital in Mainz, Germany, are an instructive example of a successful interdisciplinary team approach to the problems of pain. After 4 years of continuous work, and having treated 1000 patients with encouraging results, the authors claim that interdisciplinary pain clinics are the best means of medical care for patients suffering from chronic pain.

The anatomical basis and technical execution of a paratracheal approach to stellate ganglion block at the C6 level is described. Low dosage of local anesthetic (3 ml of l--2% lidocaine) suffices, and prevents such complications as subarachnoid introduction of a large quantity of local anesthetic, brachial plexus block, and toxic reaction to local anesthetic. The transverse process of C, is contacted just medial to the tubercle, at a depth of about 1 cm. In a 4 year experience with 155 patients treated for reflex sympathetic dystrophy, the only complication encountered was transient paralysis of the recurrent laryngeal nerve.

central gray and hypothalamus: inhibitory

Electrical stimulation to food-deprived cats was delivered to IZ. ruphe posterior hypothalamus and periaqueductal central gray. Stimulation to all three sites produced inhibition of eating behavior. Stimulation to hypothalamus and central gray also yielded an aversive effect. Stimulation to raphe produced only inhibition with no sign of aversion. The authors concluded that studies of behavioral inhibition should include tests for aversion and that behavioral inhibition produced by raphe stimulation is due to activation of a central inhibitory process.
