In this report the clinical, laboratory, and histopathologic findings of nine children with polyarteritis are reviewed. All have had evidence of systemic involvement. Eight presented with fever, calf pain, erythematous painful nodules, and elevation of the acute-phase reactants. All were treated with prednisone at a dosage of 2 mg/kg/day. All of the children are alive but have had relapses at least once during the course of tapering the dosage of corticosteroids. Serious complications of disease have included myocardial infarction, hypertension, and impaired renal function.

Geriatric patients are preferentially involved in ischemic bowel disease. The sudden occlusion of the large mesenteric arteries (a. mesenterica superior (more frequently) and inferior) is followed by intestinal gangrene and peritonitis with a poor prognosis and a high letality (greater than 90%). In chronic intestinal ischemia the leading clinical symptom is postprandial pain ('claudicatio intestinalis'). In some cases of acute mesenteric artery occlusion no embolus or thrombus will be found. In these cases the circulation in the arteriosclerotic vessels falls below a critical value due to cardiac insufficiency, shock, digitalis overdose and others. In less severe ischemia the mucosa is involved being most sensitive to O2 deprivation. It usually regenerates within a few days. This form is found more frequently in the colon than in other parts of the gut (about 40%): ischemic colitis. The therapy - if possible in acute, fulminant ischemia or if necessary in chronic intestinal ischemia - is surgical consisting in reconstructive procedures of the mesenteric circulation.

The use of potent narcotics to control severe pain should be of short duration and limited to patients with acute diseases or inoperable or metastatic cancer who require long-term relief. Continued and prolonged use of narcotics in patients with chronic benign pain is not recommended because of serious behavioral consequences, the development of tolerance, and addiction liability. Long-term use of analgesic drugs in chronic pain usually produces negative behavioral complications that are more difficult to manage than the pain it was desired to eliminate. The use of antidepressant drugs in the pain regimen has been found to provide increased relief of pain and often allows the dose of narcotic analgesic to be reduced or totally eliminated.

The possibility of abolishing pain during operations by needling acupuncture points was detected in China 20 years ago. During the last years the Western World showed great interest in this method, which was tested in a great number of surgical operations. Acupuncture was successful, especially when it was introduced by a short conventional anesthesia. Of special importance seems the possible reduction of anesthetic agents. Though the mode of action of acupuncture cannot yet be explained completely, there exist three different hypotheses: Hypnosis and suggestion, neurophysiological and humoral mechanisms. An actual review on experiments concerning these theories is given.

Benoxaprofen is a potent and long-acting anti-inflammatory and antipyretic compound. Its anti-inflammatory activity has been demonstrated in carrageenan-induced oedema, in cellulose pellet granuloma and in both developing and established adjuvant arthritis tests in rats. Its antipyretic activity is greater than either aspirin or paracetamol in tests inducing pyrexia with yeast of 'E' pyrogen in rats and rabbits. Benoxaprofen has analgesic activity in tests where pain is accompanied by inflammation but not in other experimental models of pain. The weak prostaglandin synthetase inhibiting properties of this compound differentiate it from other acid anti-inflammatory compounds. The low ulcerogenic potential of benoxaprofen seen in animal models may be related to its relative inability to inhibit PG synthetase.

Lorazepam, a new benzodiazepine, was compared with morphine for premedication. Ten patients received morphine 10 mg/70 kg i.m. and 10 received lorazepam 4 mg/70 kg i.m. Respiratory effects were assessed from the change in slope (S) and intercept (B) of the carbon dioxide response line, using a development of Read's rebreathing method. Morphine depressed S by 47% (P less than 0.01), but after lorazepam S increased by 27% (P less than 0.05), neither drug altering B significantly. In two volunteers lorazepam was assessed by both the rebreathing and the steady-state methods; after lorazepam S was smaller by the steady-state than by the rebreathing technique. The findings for lorazepam are consistent with the known effects of sleep on carbon dioxide sensitivity. Amnesia lasting 4-8 h occurred in all patients who received lorazepam so that pain and nausea during this period were not recalled, but no patient who received morphine experienced amnesia. We conclude that lorazepam merits further study, particularly where sedation without respiratory depression is needed, as in obstetrics, and where amnesia for uncomfortable procedures is required.

A double-blind between-patient trial over 6 weeks to compare the effects of 1.6 g tolmetin daily with 4 g alclofenac daily was completed by 37 out of 44 out-patients with rheumatoid arthritis. Tolmetin proved as effective as alclofenac in relieving pain and in reducing both the articular index score and the number of inflamed joints. However, alclofenac produced a significantly greater reduction in the duration of morning stiffness, which could have been related to the timing of the initial daily dose of tolmetin. Onset of fatigue was significantly improved by both drugs. Neither treatment group exhibited any significant changes in the serum levels of IgG, IgA, and IgM, nor in the latex and sheep-cell agglutination titres. Although neither drug gave rise to serious side-effects, 3 patients (2 on tolmetin, 1 on alclofenac) were withdrawn because of skin rash, 2 (on tolmetin) because of gastro-intestinal upsets, and 1 from each group because of lack of analgesic effects.

Although the four-point relative potency assay using crossover design has proven a powerful technique for the clinical evaluation of analgesics in patients with chronic pain, excessive dropouts have made this design impractical in postoperative pain. In a relative potency assay comparing single graded intramuscular doses of morphine standard and morphine test in postoperative patients, we have managed to circumvent this difficulty while preserving many of the advantages of a complete crossover by using the "twin-crossover" balanced incomplete block design, which requires that each subject receive only two of the four possible treatments. The "twin crossover" design, coupled with a sequential decision-making process that expedites choosing the doses of the test medication which are most closely equianalgesic with the standard, yielded excellent analgesic assay sensitivity and made efficient use of our population of postoperative patients.

Using the twin crossover, balanced incomplete block design described in the previous paper, a double-blind determination of the relative analgesic potency of graded intramuscular doses of Win 20,836 (8-methoxycyclazocine) and morphine was carried out in patients with postoperative pain. Although no preliminary data at all on the human analgesic activity of Win 20,836 were available, the sequential decision-making process designed to choose the doses of the test medication most closely equianalgesic with the standard functioned efficiently to establish doses of Win 20,836 that had analgesic activity. Unfortunately, the occurrence of psychotomimetic side effects prevented the administration of doses of Win 20,836 equieffective with the morphine standard, and this necessitated substantal extrapolation of the dose-response curve of the test drug to arrive at a relative potency estimate. However, our relative potency estimate, which indicated that Win 20,836 is three to six times as potent as morphine, was dependable enough to predict with reasonable certainty that doses of Win 20,836 equieffective to the usual doses of morphine would produce an unacceptable level of psychotomimetic side effects. Clinical investigation of the drug was therefore terminated.

The present study determines the analgesic effects of morphine in grouped and isolated rats and mice. Isolated animals developed altered behavioral patterns, including mouse-killing in rats and mutual aggressiveness in mice. The analgesic effect of morphine was tested by tail compression in rats and by the hot plate for mice. Isolated rats developing mouse-killing behavior had a raised pain threshold, while indifferent animals (nonkillers) responded less to morphine. Isolated mice, particularly low aggressors, gave enhanced responses to morphine.
