The aim of the randomized multicentre double-blind study was to establish whether nonionic contrast media differ in tolerability. The controlled comparison was conducted at 4 centres on a total of 798 patients with indication for i.v. DSA and computed tomography. The nonionic contrast media Iopamidol and Iopromide with an iodine content of 300 mg/ml each were studied. The osmolality of both contrast media is virtually identical. Both groups of patients were largely homogeneous in terms of demographic data and case history. The history of allergies was positive in 32.4% of the Iopamidol group and in 32.3% of the Iopromide group. The arithmetic mean of the doses administered to each patients was 148.3 and 149.3 ml, respectively. At all 4 centres there was a higher incidence of adverse events with Iopromide than with Iopamidol. The main differences with regard to pseudo-allergic reactions was the incidence of urticarial reactions, pruritus, nausea, vomiting and coughing. 89 of the 399 patients (22.3%) receiving Iopamidol and 120 of the 399 patients (30.1%) receiving Iopromide experienced pseudo-allergic reactions. The difference between both contrast media is statistically significant (p less than 0.05). There is a 95% certainty that less pseudo-allergic reactions will occur after an Iopamidol injection than after Iopromide. Possible explanations for the differences in tolerability between the two nonionic contrast media with identical osmolality are discussed.

Epidural morphine is used for postcesarean analgesia, and nonsteroidal antiinflammatory drugs are frequently administered to relieve uterine cramps after vaginal delivery. To assess the efficacy of a combination of low-dose epidural morphine and intramuscular diclofenac sodium in postcesarean analgesia, a double-blind, randomized study was conducted. Epidural anesthesia was given to 120 parturients who were randomly allocated into four treatment groups: group A received normal saline solution, 10 mL epidurally and 3 mL intramuscularly (IM); group B received 10 mL of epidural saline solution and 75 mg (3 mL) of diclofenac IM; group C received 2 mg of morphine in 10 mL of epidural saline solution and 3 mL of saline solution IM; and group D received 2 mg of morphine in 10 mL of epidural saline solution and 75 mg of diclofenac IM. Epidural injections were given after delivery of the placenta, and IM injections were given on arrival in the recovery room. Verbal analogue pain scores were recorded at 2, 4, 8, 12, 18, and 24 h after epidural injection. Subjective scores of overall pain relief were also recorded at 24 h. Results showed that scores of overall pain relief were significantly better in group D compared with group A, B, or C (P less than 0.05). Groups A and B required more supplemental meperidine than groups C and D. None of the subjects in group D requested supplemental analgesia. Compared with the other three groups, group D experienced a better analgesic effect for both wound pain and uterine cramping pain from 4 to 18 h (P less than 0.05). Incidence of nausea or vomiting, or both, and pruritus occurred more frequently in groups C and D compared with group A or B (P less than 0.05). No bradypnea was observed during the study period. Diclofenac alone was not effective in postcesarean analgesia.(ABSTRACT TRUNCATED AT 250 WORDS)

Twenty-eight elderly patients scheduled for urological surgery were randomly assigned to receive, in a double-blind study, subarachnoid hyperbaric bupivacaine 15 mg with 50 micrograms (group A, n = 7), 25 micrograms (group B, n = 7), or 12.5 micrograms (group C, n = 7) of fentanyl or 1 ml of saline (group D, n = 7) in a total volume of 4 ml. The pattern of breathing and the ventilatory response to CO2 were studied before and 90, 150 and 480 min after the subarachnoid injection. In group A, mild pruritus and sedation occurred in five patients, while nausea, vomiting and periodic breathing occurred in two. In group B, mild pruritus and sedation were observed in four patients, while nausea and vomiting occurred in two. No significant differences in minute ventilation, respiratory drive and respiratory timing were observed between the groups. Patients receiving fentanyl 50 micrograms showed a percentual change from baseline values as function of time (slope VE/PE'CO2) significantly below baseline at 90 and 150 min (p less than 0.05). However, the baseline values in this group reverted after 480 min. No side effects were observed in groups C or D. It is concluded that subarachnoid fentanyl 50 micrograms can cause an early respiratory depression and its use as a postoperative analgesic should be avoided in the elderly.

From 1974 to 1989, a total of 24,500 aborigines at 67 villages in ten mountainous districts/towns in Taiwan were examined for the Taiwan Taenia infection and 12% were found to be infected. In order to define the clinical manifestations of taeniasis caused by the Taiwan Taenia, 1661 aborigines in ten mountainous districts were surveyed. The overall clinical rate was 76%. The clinical rate was highest among Atayal aborigines (81%), followed by Bunun (66%) and Yami (61%) aborgines and lowest among Ami aborigines (40%). Among 1153 infected people, 10% had passed gravid segments in the faeces for less than 1 year, 24% for 1-3 years, 17% for 4-5 years, 23% for 6-10 years, 16% for 11-20 years, 7% for 21-30 years, and 3% over 30 years. Twenty-six occurrences of gastrointestinal and neurological symptoms were reported by 1258 infected persons. Passing proglottides in the faeces (95%) was the most frequent sign, followed by pruritus ani (77%), nausea (46%), abdominal pain (45%), dizziness (42%), increased appetite (30%), headache (26%), etc.

Respiratory effects, nausea, somnolence, and pruritus were compared during a 48-hr period of continuous epidural morphine (n = 34) and fentanyl (n = 32) infusion in 66 patients following elective total replacement of the hip or knee joint. Respiratory effects were assessed by PaCO2. Side effects were assessed by visual analogue scale and considered to be present when the score was above 30. Assessment was made at preoperative visits then 3, 6, 12, 24, 36, and 48 hr after the epidural injection. The bolus dose and subsequent infusion rate were 3,900 +/- 1,300 micrograms and 427 +/- 213 micrograms.hr-1 for morphine, and 85 +/- 46 micrograms and 56 +/- 27 micrograms.hr-1 for fentanyl. Pain relief was similar in both groups. In the morphine group, PaCO2 elevation and nausea occurred over a period of more than 12 hr (P less than 0.05). In the fentanyl group, there was no PaCO2 change, and nausea was confined to the first few hours. Nausea was more severe (P less than 0.01 at six hours and more frequent (24 hr cumulative incidence, 53 vs 28%, P less than 0.05) in the morphine group. Somnolence was prominent within several hours in two-thirds of patients in both groups. Somnolence continued to decline thereafter in the morphine group, but it was demonstrable in approximately half of the patients throughout the second day in the fentanyl group. The incidence was higher in the fentanyl group at the 48th hr (P less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Thirty women (28 of childbearing age and 2 in the menopause), affected by acute Candida albicans vulvovaginitis were treated orally with a new antimycotic triazole derivative, itraconazole. Twenty patients were administered with 200 mg/die of itraconazole for three days. In tests carried out 7 and 30 days after the end of therapy the following results were observed. Negative cultures in 95% of patients and in 75% of patients; absence of leukorrhea in 60% of patients and in 65% of patients; disappearance of pruritus in 95% of patients and in 80% of patients. Ten patients were administered with an acute dose of itraconazole (400 mg). In the same tests, carried out 7 and 30 days after the end of therapy reported above the results were as follow. Negative culture in 80% and 60% of patients; absence of leukorrhea in 50% and 60% of patients; absence of pruritus in 70% and 50% of patients. In the first group of patients one case of slight nausea was reported whilst in the second group there were two cases of nausea, one of gastralgia and one of urticaria. No systemic side-effect was seen.

The efficacy and tolerability of low, intermittent doses of co-trimoxazole (160 mg trimethoprim and 800 mg sulfamethoxazole given Monday, Wednesday, Friday) for prophylaxis against Pneumocystis carinii pneumonia (PCP) was assessed retrospectively in 116 patients with the acquired immunodeficiency syndrome (AIDS) and AIDS-related complex at high risk of PCP. 92% were receiving concomitant zidovudine. 71 with previous episode(s) of PCP were followed a mean of 18.5 months (range 3-42). 45 without past PCP but with depletion of CD4 cells to less than 200/microliters were observed for a mean of 24.2 months (range 9-40). PCP did not develop in any patient on co-trimoxazole. 33 (28%) had side-effects, mainly rash, pruritus, and nausea. 15 discontinued co-trimoxazole, but only 11 (9%), who withdrew in the first month, were clearly drug-intolerant. Thus, low-dose, thrice weekly co-trimoxazole completely prevents AIDS-associated PCP, is cost-effective, and well tolerated by more than 85% of patients. Controlled comparisons of this regimen with other prophylactic agents are warranted.

The aim of the regional administration of opioids is to provide an efficient and prolonged analgesia. Then, opiates can be useful for postoperative analgesia and for the treatment of chronic pain of malignant origin. Analgesia is correlated with several adverse effects of which the most frequent are nausea and itching and the most severe is respiratory depression. Beside the adverse effects, other properties of opiates could be responsible of favourable effects which can be taken in advantage in specific indications. In the postoperative period, epidurally administered opioid can attenuate the neuroendocrine and metabolic responses to surgery and pain. This effect is responsible of a reduction of the resistance to insulin and of a better nutritional balance, especially after major abdominal surgical procedures. Opioids also act by a reduction of the motor functions of the bowel, which perhaps could reduce the incidence of anastomotic breakdowns. Finally, other effects have been reported, as anecdotes, such as the treatment of spasm after bilateral replantation of the ureters, neurologic bladder dysfunctions and enuresis. Spinal administration of opioids has also been used as a treatment of premature ejaculation.

Sharp pain is conducted rapidly by myelinated delta A fibers and diffused pain slowly by nonmyelinated C fibers to pseudobipolar neurons in the posterior ganglion and from there to neurons located in the posterolateral horn of the spinal cord. From here on nociferous impulses are transmitted by excitatory peptides (e.g. substance P) or amino acids (e.g. glutamate, aspartate) through interconnecting neurons of the pain pathways, primarily on the contralateral side, to the brain stem and from there to the sensory cortex, where they are appreciated and acted upon. There are specific inhibitory receptors located on axon terminals, near to the release sites of the excitatory amino acids and peptides. Stimulation of these receptors by their appropriate ligands such as endogenous (e.g. enkephalis, endorphins) or exogenous opioids, clonidine, serotonin, somatostatin inhibits the release of excitatory neurotransmitters and relieves pain. There are at least 3 different opioid receptors, called mu-, kappa- and delta-receptors in the spinal cord. These can be differentiated from one another by their specific affinity toward different endogenous or exogenous opioids and the pure narcotic antagonist, naloxone. It appears that the nociferous impulses transmitted by parallel pathways equipped with different inhibitory receptors have to be integrated to produce pain sensation and partial inhibition of transmission in different pathways or complete inhibition in one of the pathways may relieve pain. In recent years the concept of "selective spinal analgesia" has been applied clinically for the relief of postoperative, obstetrical and chronic pain. At first it was expected that the intrathecal or peridural administration of morphine will produce analgesia without the side effects of systemically administered morphine. It soon became evident, however, that intrathecally and peridurally administered morphine after several hours of delay reaches the fourth ventricle and by stimulating mu-receptors may cause respiratory depression and other undesired effects (e.g. nausea, vomiting, pruritus). Several different approaches are being investigated for the production of selective spinal analgesia without side effects. They include: a. the use of more lipophilic, long-lasting opioids (e.g. lofentanil) which would be almost completely absorbed by the spinal cord and therefore would not reach the medullary centers; b. the development of opioids with specific affinity to kappa- and for delta- and little or no affinity to mu-receptors, primarily responsible for side effects; and c. combining lower doses of opioid agonists with alpha 2-adrenergic agonists (e.g. clonidine) or with somatostatin. It is conceivable that in the not-too-distant future, it will be possible to achieve through these measures, selective spinal analgesia without side effects.

Forty-four patients were treated with a continuous infusion of lumbar epidural hydromorphone (0.05%) after thoracic operations. Postoperatively, visual analog pain scores were obtained. On postoperative day 1 and 2, more than 90% of the patients experienced either no pain (visual analog pain scale = 0) or mild pain (visual analog pain score = 1 to 3) at rest. The incidence of side effects (hypoventilation, pruritus, and nausea) was less than reported with other epidurally administered opioids. Continuous infusion of lumbar epidural hydromorphone produced safe, predictable analgesia after thoracotomy.
