Anxiety and pain in surgical patients
337 Anxiety and pain in surgical patients A. Martinez-Urrutia, J. Consult. clin. Psychol., 43 (1975) 437-442 This istudy investigated the effects of surgery on state anxiety (A-state) and perceived pain in 59 white male surgical patients. The Melzack-Torgerson Pain Questionnaire, the State-Trait Anxiety Inventory (STAI), and the Fear of Surgery Scale (FSS) were given the day before the operation and again 10 days after surgery, The results indicate that surgery as a physical threat has an effect on A-state but not on anxiety as a personality disposition (trait anxiety; A-trait). The correlation of A-state and magnitude of reported pain postsurgery, but not presurgery, was attributed to the existence of little pain variance before surgery, and to realistic concern over pain following surgery.

H. Akil, D.J. Mayer and J.C. Liebeskind, Science, 191 (1976) 961-962 Analgesia produced by focal electrical stimulation of the brain is partially reversed by the narcotic antagonist naloxone. The absence of complete reversal does not appear to be caused by inadequate doses of naloxone since doses higher than 1 mg/kg of body weight did not increase the antagonism. It is suggested that stimulation-produced analgesia may result, at least in part, from release of an endogenous, narcotic-like substance, such as that recently reported by other investigators,

Med., 37 (1975) 341-351 Patients with the fibrositis syndrome uniformly complain of disturbed sleep together with muscular pains and stiffness on waking, The authors link these by their findings that 10 patients suffering fibrositis developed a similar EEG pattern with the alpha rhythm appearing in non-REM sleep (alphadelta sleep). They found the same pattern when 6 normal non-athletic males were deprived of stage 4 sleep. They too developed stiff sore muscles, lowered pain threshold and mood disturbances.
