A total of 555 hypertensive patients took part in a 2-year multicenter, open-label study to determine the efficacy, tolerance, and safety of long-term therapy with ramipril. In the beginning, all patients were to receive 5 mg of ramipril/day. The dosage was then adjusted in accordance with response to treatment and ranged from 1.25-20 mg of ramipril daily. Of these patients, 129 also received 25 mg of hydrochlorothiazide daily at some point during the trial. To evaluate whether tolerance to ramipril developed during long-term treatment, a subgroup of 202 patients was analyzed for efficacy maintenance. Prior to enrolling in the 2-year study, these patients had received ramipril monotherapy in a short-term, double-blind study and had been classified as responders, i.e., their diastolic blood pressure had been maintained at less than or equal to 90 mm Hg. At the end of 104 weeks of treatment, 45.9% of patients were on 2.5 mg of ramipril alone and 43.6% were on 5 mg of ramipril alone. Only four patients required the addition of 25 mg of hydrochlorothiazide. No clinically important changes occurred, and kidney function was well maintained. The most frequently reported adverse events excluding intercurrent illnesses were dizziness/vertigo (6%), asthenia (4%), nausea (3%), headache (2%), and abdominal pain, gastrointestinal disorder, rash, and increased cough (1% each). Ramipril was safe, effective, and well tolerated in the long-term treatment of patients with mild-to-moderate essential hypertension.

The investigators conducted a clinical study on antithrombotic effectiveness in ischemic stroke at Siriraj Hospital Medical School, Mahidol University from May 1987 to May 1989. Twenty-nine patients, 16 males and 13 females were enrolled in the study. The ages of the patients ranged from 30-87 years with a mean age of 63 +/- 11 years. Ticlopidine (250 mg) could significantly inhibit platelet aggregation induced by ADP and collagen within 24 hours of drug administration. After 1 week to 6 months, only aggregation by ADP was still inhibited significantly without significant effects on fibrinolytic activity and prostacyclin. Hematocrit was significantly decreased at the 1st and 2nd month of treatment. Serious side effects were skin rash and severe headache while the other common ones were dizziness, and diarrhea but these effects disappeared without discontinuing the drug. Most patients who suffered from nausea, diarrhea and headache, had temporary elevated SGPT. It may be concluded that only half of the recommended dose of ticlopidine has inhibitory effects on both phases of ADP-induced aggregation without interfering with fibrinolytic activity and can maintain prostacyclin. However, it also possesses either serious or common side-effects. This drug, therefore, should be used with the awareness of the clinician.

The authors report three trials of B-lactams and carbapenems for soft tissue infections treated on a surgical service: 1) cefmetazole versus cefoperazone, n = 44; 2) cefotetan versus cefoxitin, n = 24; and 3) meropenem versus imipenem, n = 44. A total of 138 hospitalized patients were enrolled with 112 meeting evaluability criteria. Four hundred twenty-three isolates were cultured (mean, three/patient) of which 67 per cent were aerobes and 33 per cent anaerobes. Cure rates for each trial were: 1) 93 per cent; 2) 92 per cent; 3) 100 per cent. Failures were caused by resistant organisms (Streptococcus group D, Bacteroides fragilis and Pseudomonas) appearing in incompletely drained infection sites. Three patients receiving meropenem had adverse effects (headache, nausea) and one receiving cefoxitin (truncal rash). Operative drainage and debridement remain the critical elements in therapy. Agents with longer half lives allowing twice daily dosing (cefmetazole and cefotetan) were as effective and less expensive than multiple doses of short-acting agents. The extended spectrum carbapenems are most useful for severe infections or resistant organisms.

We compared two nonionic contrast agents (ioxaglate and iohexol) with an ionic agent (Renografin-76) on the effects of ventriculography and coronary arteriography on the hemodynamics, electrocardiography, and serum creatinine in one hundred consecutive patients. Patients were randomized to nonionic or ionic groups and were further evaluated regarding the effect of fluid loading prior to catheterization. The ionic agent more often produced subjective reactions (rash, nausea/vomiting). Following ventriculography, both ionic and non-ionic agents produced an increase in left ventricular end diastolic pressure and this effect was undetermined by fluid loading. Nonionic agents decreased aortic diastolic pressure following ventriculography and this effect was unaltered by fluid loading. In contrast, the ionic agent produced profound hemodynamic changes (drop in both systolic and diastolic pressures) following coronary arteriography and these effects were blunted by prior fluid loading. The ionic agent produced significantly greater heart rate slowing and prolongation of the QT interval than the nonionic agents, suggesting that the latter are potentially less arrhythmogenic. Comparing the two non-ionic agents, we found that both decreased aortic diastolic pressure and increased left ventricular end diastolic pressure following ventriculography. Iohexol produced greater heart rate slowing than did ioxaglate, though the increase was minor compared to the ionic agent. Neither nonionic agent appeared to significantly affect serum creatinine. In conclusion, the two nonionic agents appeared to offer significant advantages over the ionic agent in ventriculography and coronary arteriography.

Amonafide (benzisoquinolinedione, nafidimide, NSC 308847) is an anticancer agent that functions as a DNA intercalator. Sixteen patients with stage III or IV non-small-cell lung cancer who had not previously received chemotherapy were given amonafide at an initial dose of 300 mg/m2 i.v. daily for 5 days every 21 days. No major objective responses were observed among the 14 patients adequately treated (95% confidence limits 0-20%). Local reactions at the injection site or phlebitis were seen in 14 of the 16 patients. Leukopenia (44%), nausea or vomiting (38%), and thrombocytopenia and rash (each 25%) were also noted. With the low response rate and the toxicity observed, amonafide at this dosage and schedule has limited use in the treatment of non-small-cell lung cancer.

Acute iridocyclitis is a rare hypersensitive reaction to quinidine treatment. The third case in the literature is reported here. A woman aged 80 years developed pyrexia, anorexia, nausea, skin rash and hepatic dysfunction after treatment with quinidine for two weeks. Four weeks later, while still receiving quinidine, she developed acute iridocyclitis. Quinidine treatment was withdrawn, the eye symptoms were treated and the patient recovered rapidly without complications. This case report draws attention to quinidine as a possible cause of iridocyclitis of unknown origin.

Dihydroergokryptine has been evaluated in the prophylaxis of headache attacks in patients with migraine without aura. The study was controlled vs dihydroergotamine with a double-blind crossover design. After a 1-month run-in period, 30 patients were randomized into two groups and submitted to 4 months treatment with dihydroergokryptine 10 mg b.i.d. or dihydroergotamine (controlled release) 5 mg b.i.d. The treatment was repeated in crossover after 2 months washout. The clinical patients' evaluation was determined by monthly Pain Total Index recording, headache days/month and analgesic consumption. The patients were considered responsible when Pain Total Index decreased by 50% or more in 1 or more months of each treatment period; otherwise the patients were considered unresponsive. The response rate to dihydroergokryptine was 66% while 48% of cases were responsive to dihydroergotamine. The response rate to both treatments was 41%, while 26% did not respond to either treatment. Seven cases unresponsive to dihydroergotamine responded positively to dihydroergokryptine while two cases only, resistant to dihydroergokryptine, responded positively to dihydroergotamine. Three cases dropped out during treatment with dihydroergotamine due to gastric pain and nausea, while they did not show any side effects during dihydroergokryptine therapy. During treatment with dihydroergokryptine there was one case of skin rash which disappeared after drug withdrawal. In conclusion, dihydroergokryptine appears to be an effective drug for the prophylaxis of migraine attacks.

The major use of N-acetylcysteine in clinical toxicology is in the treatment of acetaminophen (paracetamol) overdosage. The hepatorenal toxicity of acetaminophen is mediated by a reactive metabolite normally detoxified by reduced glutathione. If glutathione is depleted, covalent binding to macromolecules and/or oxidation of thiol enzymes can lead to cell death. Oral or intravenous N-acetylcysteine or oral D,L-methionine mitigates acetaminophen-induced hepatorenal damage if given within 10 hours, but becomes less effective thereafter. In vivo, N-acetylcysteine forms L-cysteine, cystine, L-methionine, glutathione, and mixed disulfides; L-methionine also forms cysteine, thus giving rise to glutathione and other products. Oral therapy with N-acetylcysteine or methionine for acetaminophen poisoning is contraindicated in the presence of coma or vomiting, or if activated charcoal has been given by mouth. Nausea, vomiting, and diarrhea may also occur as a result of oral N-acetylcysteine administration. Anaphylactoid reactions including angioedema, bronchospasm, flushing, hypotension, nausea/vomiting, rash, tachycardia, and respiratory distress may occur 15-60 minutes into N-acetylcysteine infusion (20 hours intravenous regimen) in up to 10% of patients. Following accidental intravenous overdosage, the adverse reactions of N-acetylcysteine are similar but more severe; fatalities have occurred. A reduction in the loading dose of N-acetylcysteine may reduce the risk of adverse reactions while maintaining efficacy. Administration of N-acetylcysteine for a longer period might provide enhanced protection for patients in whom acetaminophen absorption or elimination is delayed. N-acetylcysteine may also have a role in the treatment of toxicity from carbon tetrachloride, chloroform, 1,2-dichloropropane, and other compounds. The possible use of N-acetylcysteine and other agents in the prevention of the neuropsychiatric sequelae of acute carbon monoxide poisoning is an important area for future research.

A multicentre study of IL2 and IFN alpha has been performed in 58 patients with metastatic melanoma. The scheme consisted of IL2 3.0 BRMP MU/m2/d as a continuous infusion for 4 d combined with subcutaneous administration of IFN alpha 6 MU/m2/d, day 1 + 4. The cycle was repeated every 2 weeks for a maximum duration of 26 weeks. 54 patients were evaluable for response. One (2%) achieved a complete and 10 (19%) a partial response. 19 (35%) patients were stable and 24 (44%) showed progressive disease. Common side-effects included fever, chills, fatigue, skin rash, anorexia, nausea and diarrhoea. Hypothyroidism was noted in 10% of the patients. These results show that this regimen of IL2 and IFN alpha is active but, in contrast to what could be expected, not superior to IL2 alone possibly due to suboptimal dosing. In an ongoing study in Rotterdam and Nijmegen, a more intense schedule was chosen, consisting of three daily i.v. doses of IL2 4.5 BRMP MU/m2 and IFN alpha 3.0 MU/m2 for 5 d. This regimen is repeated at intervals of 3 weeks for a total of three cycles. Presently, nine patients have been entered. One patient achieved a complete response, four a partial response (overall 56%), three had stable disease and one progressed. Toxicity was severe and treatment was prematurely stopped in five patients: myocardial infarction (one patient), atrial fibrillation (one patient), negative T waves and myocardial hypokinesia (one patient) and psychosis (two patients). This regimen can only be justified if the therapeutic results are superb, which has yet to be awaited.

In a double-blind, randomized, multicenter study, 400 women with symptoms of acute urinary tract infections were treated with either a 7-day course of temafloxacin hydrochloride (400 mg once a day; n = 204) or a 10-day course of trimethoprim (160 mg) and sulfamethoxazole (800 mg) (TMP-SMZ) twice daily (n = 196). The bacteriologic cure rates at 5 to 9 days posttherapy were 100% in the temafloxacin group and 97% in the TMP-SMZ group (P = 0.035). The clinical cure rates were 93% in the temafloxacin group and 95% in the TMP-SMZ group (P greater than 0.1). Adverse events, including nausea, vomiting, rash, headache, and dizziness, were experienced by 19.6% of the temafloxacin group and 23.5% of the TMP-SMZ group. Transient leukopenia occurred in 0.5 and 4.1% of the temafloxacin and TMP-SMZ groups, respectively. Temafloxacin, 400 mg once a day for 7 days, appears to be at least as safe and effective as a 10-day course of TMP-SMZ in the management of acute urinary tract infection in women.
