Fifty-one patients with moderate (11/51) and severe (40/51) cancer pain were given a new non-narcotic analgesic -Tromadol HCL capsule (THC). In 42 of these patients, partial relief was obtained with an average relief time (ART) of 4.1 hours. The average starting time was 58 minutes. Pain relief rate (PRR) in moderate and severe pain was 82% (P = 0.945), and the ARTs were 7.4 hr. and 3.2 hr., respectively (P = 0.005). In 43 patients who were entered into a randomized study with control drugs of AT-237 (36 cases) or Anfendein (7 cases), the PRR was 60.4% (26/43), ART was 1.3 hours. The PRR and ART of THC and control drugs were statistically significant (P less than 0.001 and P = 0.023). Within adequate dose range, increase of THC dose could improve its analgesic effect (P = 0.011). The main side-effects were: somnolence (37.3%), nausea (35.3%), dizziness (33.3%), palpitation and anorexia (25.5%) and constipation (9.8%) which did not necessitate the suspension of THC administration.

Within the frame work of lumbar myelography, 158 patients were entered in a double-blind study in order to test a dimeric contrast medium (iotrolan) against a monomeric one (iopamidol), both of them non-ionic. A three-step scheme was applied to evaluate the X-ray pictures with respect to contrast quality. Particular attention was paid to the visibility of details, i.e. the nerve root and its course, as well as to how well it could be distinguished in the nerve root sheath. On the basis of a high level of significance (P less than 0.05), comparison of the two contrast media showed no difference in contrast quality. Sixty-nine percent of the examinations using iotrolan resulted in excellent contrast quality, whereas the corresponding very good results using iopamidol lay at 76%. Twenty-nine percent of the patients examined with iotrolan and 27% of those examined with iopamidol showed side effects. Headache occurred most frequently, followed by nausea, dizziness and neck pain. Sixty percent of the patients suffering from postmyelographic reactions reported delayed headache, which occurred most often with iotrolan rather than iopamidol. As for manifestation of other postmyelographic side effects, there were no significant differences (P less than 0.05, Fischer's test) between the two groups of contrast media.

Human urine samples, purified on octadecasilyl-silica cartridges, contained immunoreactive angiotensin I, II, arginine vasopressin and oxytocin. The daily excretion of these peptides in healthy volunteers was 190.00 +/- 38.43 (n = 12), 17.48 +/- 3.09 (n = 12), 63.43 +/- 14.84 (n = 8) and 13.52 +/- 1.42 (n = 7) pmol/24 hr, respectively (mean +/- s.e.m.). Patients with a history of anaphylactoid reactions to drugs or food additives showed clinical symptoms such as urticaria, flush, nausea, dizziness and hypotension after oral provocation with cyanocobalamine, propyphenazone, acetylsalicylic acid and sodium benzoate. In five of the seven patients, angiotensin I and II were increased several fold in the urine fractions after symptoms were reported. The average increase in the urine concentration of both peptides was fourfold and 5.5-fold. In three out of five patients, the mean excretion of arginine vasopressin and oxytocin immunoreactive material was also elevated by a factor of 5.7 and 4.4, respectively. Oral provocation with a placebo failed to elicit anaphylactoid symptoms or an increase in the urine levels of angiotensin I or angiotensin II. Angiotensin I and angiotensin II-like immunoreactivity could be characterized on HPLC as Ile5-angiotensin I, Ile5-angiotensin II and angiotensin II metabolites. HPLC characterization of immunoreactive arginine vasopressin and oxytocin in two different gradient systems showed retention times different than the retention times of the corresponding synthetic standard peptides indicating that both peptides are not authentic AVP and OXT. These results suggest that angiotensin I and angiotensin II may be involved in the clinical events observed during some forms of anaphylactoid reactions.

The efficacy and safety of prophylactic intravenous ondansetron in preventing postoperative nausea and vomiting was investigated in a randomized, stratified, double-blind, placebo-controlled, dose-comparison study of 580 ASA physical class I and II female outpatients undergoing gynaecological surgery and receiving general anaesthesia. Patients received either ondansetron 1, 4 or 8 mg, or placebo i.v. immediately prior to a standardized technique for induction and maintenance of anaesthesia. All patients were intubated and received nitrous oxide and a narcotic. All doses of ondansetron were significantly more effective than placebo in preventing emesis over the 24 h postoperative period. Ondansetron significantly decreased nausea and emesis scores over 24 h postoperatively without causing sedation. No changes in laboratory parameters (haematology, blood chemistry, and liver enzymes) or vital signs (heart rate, blood pressure, and respiratory rate) were observed. Headache and dizziness were the most common side-effects; however, their incidence was the same as with placebo. Ondansetron was generally well tolerated, as evidenced by an adverse event, laboratory safety, and vital sign profile similar to placebo. Ondansetron 4 mg was found to be the optimal prophylactic i.v. dose for female outpatients over the entire 24 h postoperative period. Higher doses may offer an added benefit in some patients, such as those with a history of nausea and vomiting following general anaesthesia.

A military tank driving simulator has recently been introduced as a training aid for tank drivers in the Israel Defense Forces. Reports of nausea and vomiting among the first users of the simulator launched our investigation of the possible existence of a motion sickness-like syndrome among simulator drivers. Although the 59 subjects drove the simulator without any report of vomiting, other motion sickness-like symptoms were frequently reported. A comparison of symptoms reported after simulator and real tank driving show that dizziness, nausea, disorientation and hypersalivation were more frequently reported by simulator drivers and were of greater intensity. However, sweating and drowsiness were more prevalent among real tank drivers. The objective effect of driving the simulator was evaluated by instability and performance tests that were conducted before, during and after driving the simulator. A greater decrement in test results was observed among subjects reporting higher frequency of motion sickness-like symptoms.

The therapeutic efficacy and toxicity of a high-dose (25 mg/kg) mefloquine regimen (M25) and the currently recommended regimen of 15 mg/kg (M15) were compared in 199 patients with acute falciparum malaria in an area with deteriorating multidrug resistance on the Thai-Burmese border. The clinical and parasitologic responses were significantly more rapid with M25. The incidence of treatment failures by day 7-9 was 7% for M15 and 1% for M25 (P = .03) and had increased to 40% and 9%, respectively, by day 28 (P < .0001). Overall failure rates were highest in children (P = .02). Parasite clearance times were a good predictor of the therapeutic response; all patients with parasitemia persisting > 5 days after treatment experienced subsequent recrudescence. Side effects were dose-related and included dizziness, anorexia, nausea, vomiting, and fatigue. Although vomiting < 1 h after treatment was more likely in young children, children overall tolerated mefloquine better than adults, and men better than women. The optimum treatment dose of mefloquine in this area is 25 mg/kg.

The authors report six patients with acute endosulfan intoxication. The symptoms of nausea, vomiting, headache, and dizziness began 2.7 +/- 0.5 h after ingestion; in four cases the patients had been hospitalized but were asymptomatic. All had severe metabolic acidosis with high anion gap and hyperglycemia; five of six had decreased blood platelets. Three patients had pulmonary aspiration, and five required mechanical ventilation. The one fatality followed acute renal failure, disseminated intravascular coagulation, thrombi in the pulmonary arteries and aorta, and cardiogenic shock. In this patient the blood endosulfan was 2.85 mg/L versus a mean of 0.48 mg/L in the survivors.

Data from four double-blind studies of the treatment of patients with rheumatoid arthritis or osteoarthritis were combined. For 4 to 12 weeks, 747 patients received Arthrotec, a combination of 50 mg of diclofenac and 200 micrograms of misoprostol, and 754 patients received 50 mg of diclofenac; the drugs were given twice or three times daily. The five most commonly reported adverse events were abdominal pain by 23.2% of the diclofenac/misoprostol patients and 19.8% of the diclofenac patients; diarrhea by 19.9% and 11.3%; nausea by 11.8% and 6.5%; dyspepsia by 11.2% and 7.8%; and flatulence by 8.0% and 3.1%. Other adverse events, reported by similar proportions of both treatment groups, included headache, gastritis, dizziness, vomiting, and constipation. In the diclofenac/misoprostol-treated patients, the abdominal pain and diarrhea were rated mild in 30.6% and 24.3%, moderate in 49.1% and 51.4%, and severe in 20.2% and 24.3%. Serious adverse events occurred in eight of the diclofenac/misoprostol-treated patients and in 13 of the diclofenac-treated patients; 12.6% and 10.1%, respectively, were withdrawn from the study because of adverse events. Results of laboratory tests of hepatic and renal function were similar in the two treatment groups.

Fifteen degassers were acutely exposed over several days to high concentrations (> 60 ppm) of benzene during removal of residual fuel (degassing) from shipboard fuel tanks. Medical surveillance evaluation mandated by the Occupational Safety and Health Administration's (OSHA) Benzene Standard initially revealed 11 workers (73%) reporting neurotoxic symptoms while degassing. Workers with more than 2 days (16 hours) of acute exposure were significantly more likely to report dizziness and nausea than those with 2 or fewer days of acute exposure. Repeated laboratory analyses performed over a 4-month period after the acute exposure revealed at least one hematologic abnormality consistent with benzene exposure in 9 (60%) of these degassers. One year later, 6 workers (40%) had persistent abnormalities; an additional worker with normal hematologic parameters at the time of our initial evaluation subsequently developed an abnormality consistent with benzene exposure. Numerous large granular lymphocytes were observed on 6 (40%) of the peripheral blood smears. Despite these laboratory findings, there were no significant associations between the presence of hematologic abnormalities and either the number of hours of acute benzene exposure or the duration of employment as a degasser. Volatilization of benzene from the residual fuel was the suspected source of benzene in the headspace of tanks. Confined space exposure to petroleum products may be exposing workers to benzene at levels above the OSHA Short-Term Exposure Limit (STEL). This situation warrants further study.

At the beginning, the way intrathecal morphine was used for postoperative pain relief was quite unfortunate, because the doses derived from experience with morphine-tolerant cancer patients were considerably too high and respiratory depression occurred frequently. Subsequent dose-finding studies showed that the doses of morphine used initially could be reduced by a factor of ten without loss of the analgesic effect and with a marked reduction in side-effects. No respiratory depression has been reported when doses below 0.1 mg morphine are used. METHOD. In this prospective study the effect of 0.06 to 0.08 mg intrathecal morphine, mixed with the local anaesthetic for spinal anesthesia, was investigated in surgical patients aged 21 to 81 years, ASA grade I or II, scheduled for orthopaedic operations or herniorraphies. Thirty unpremedicated patients were enrolled in the study and were, after informed consent, randomly allocated to a control group without morphine or to a morphine group. The analgesic effect was assessed by the time interval between the administration of the spinal anaesthesia and the first demand for an analgesic medication. The mood state was evaluated with the adjective checklist of Janke and Debus 6 h after the spinal anaesthesia. RESULTS AND DISCUSSION. In the control group half of the patients asked for an analgesic medication within 275 min (median) after the spinal anaesthesia, and all patients within 420 min, whereas in the morphine group half of the patients asked for an analgesic within 1170 min (median). Seven patients had not required an analgesic at the termination of the observation period 20 h after the spinal anaesthesia. The mood status showed no difference between the two groups, in particular, no dizziness or drowsiness after morphine. There was no difference in the incidence of side-effects such as nausea or urinary retention between the two groups. Pruritus was not reported spontaneously but was found upon questioning in five patients. It was in no case disturbing. CONCLUSIONS. Morphine (0.06 to 0.08 mg) mixed with the local anaesthetic for spinal anaesthesia provided for an analgesia of more than 20 h duration in half of the patients. This technique is safe, simple, reliable and virtually free of side-effects. No particular supervision due to the administration of intrathecal morphine is necessary in this dose range if systemic opiates are avoided. If the analgesia is unsatisfactory, a non-opioid analgesic is recommended.
