Simultaneous measurements of pain rating, withdrawal reflex, and skin resistance reaction with non-painful and painful electrical stimuli were performed on 15 healthy male volunteers. Eight different intensities were delivered in standardized randomized order. Each intensity appeared 10 times. ⋯ Graphical evaluation in double logarithmic scales led to systematic errors causing higher exponents. Compound relations, like skin resistance reaction or withdrawal reflex amplitude as function of subjective estimation, could also be approximated by power functions, with parameters predictable from stimulus-reaction functions. No change in exponent was observed when subjective estimation turned from pre-pain to pain.

Comparative Study Clinical TrialDouble-blind, multiple-dose comparison of buprenorphine and morphine in postoperative pain.
The analgesic profile and side-effects of buprenorphine 0.3 mg and morphine 10 mg intramuscularly were compared postoperatively in a double-blind, non-crossover, multiple-dose study. When the patient complained of moderate to severe postoperative pain after halothane-relaxant anesthesia for upper abdominal surgery, the first test dose of either drug was given. Subsequent similar doses of buprenorphine 0.3 mg or morphine 10 mg were given when required (maximum ten doses). ⋯ Other effects of the two drugs on vital signs were similar. The incidence of other side-effects was fairly similar after both analgesics. The patients' subjective appraisal favoured buprenorphine.

Morphine 2 mg was injected directly into the intrathecal space in 33 patients. In the nonoperative group (group I) morphine was given with 2 ml saline solution; in the operative group (group II, 21 patients) morphine was given with 2 ml 10% glucose solution immediately before induction of anaesthesia. The onset of pain relief occurred after 12 to 35 min and the duration of analgesia was 14 and 18 35 min and the duration of analgesia was 14 and 48 hours. ⋯ In group I bladder insufficiency occurred in 2 cases. The disturbed bladder function recovered spontaneously in a few hours after morphine application. Respiratory depression was treated successfully with naloxone.

Case ReportsNeck pain due to acute suppurative thyroiditis and thyroglossal duct abscess.
One case of acute suppurative thyroiditis and one case of thyroglossal duct abscess are presented and discussed. Although they may often present similar symptoms and signs, they need to be differentiated from each other and from other causes of painful thyroid-related neck masses to ensure appropriate therapeutic intervention. Techniques and new developments helpful in differential evaluation, including thyroid radioscintigraphy and ultrasonography, are discussed.

An experiment was conducted to investigate the conditions under which sensory information has beneficial versus detrimental value as preparatory information to assist individuals in coping with stress. Fourteen high fear and twelve low fear college women underwent exposure to the cold pressor test. ⋯ Distress judgments made during the cold pressor showed (a) that sensory information effectively reduced distress for low fear women, but (b) sensory information exacerbated the distress of high fear women--at least during early portions of the cold pressor test. The data generally support Leventhal's (1979) perceptual-motor theory of emotion and have pragmatic implications for those persons who provide preparatory information to individuals anticipating a stressful encounter.
