Sixty-five patients with recurrent aphthous stomatitis participated in a double-blind study to evaluate levamisole. Nineteen of 34 patients improved on levamisole and only five of 31 patients improved on placebo (P less than 0.004, chi-square with two degrees of freedom). After breaking the code and switching placebo p…

Clenbuterol is a beta 2-sympathomimetic bronchodilator. In a double-blind cross-over trial in 19 asthmatic patients with reversible airways obstruction, oral administration of both clenbuterol (40 microgram) and salbutamol (4 mg) caused significantly greater increased in peak expiratory flow rate (PEFR) than placebo, t…

The prophylactic effectiveness of propranolol (80 to 120 mg per day) in 18 migraine patients was compared with a placebo group of 19 migraine patients in a double blind study without cross over for a treatment period of six and twelve weeks. A statistically significant difference in effect could not be ascertained. The…

Corynebacterium parvum was administered to sixteen patients with malignant tumors submitted to repeated chemotherapy courses. A total of 428 injections of C. parvum at a dose of 3.5 mg/m2 in weekly, biweekly and monthly administration was given between the chemotherapy courses. Injection of C. parvum was followed by fe…

The effect of calcium dobesilate on capillary resistance and background retinopathy was compared with placebo in a double-blind cross-over trial on 18 diabetics. Each treatment lasted 8 months. The trial produced no evidence in favour of a significant beneficial effect of calcium dobesilate on the capillary resistance…

A total of 219 acute superficial abscesses was treated. Patients were randomly allocated to one of four treatment groups--primary suture with or without antibiotics and free drainage with or without antibiotics. No difference could be detected between the groups in duration of healing time. Eleven per cent of all absce…

A new anticholinergic aerosol, ipratropium bromide, was compared in a double-blind cross-over trial with an established preparation, deptropine citrate, and placebo in 16 patients with defined asthma or chronic bronchitis. Ipratropium bromide produced a significantly greater and more rapid bronchodilation than did dept…

In a comparative trial, buprenorphine 0-3 mg or morphine 10 mg was administered intramuscularly to patients post-operatively. The new drug buprenorphine produced more pain relief than morphine and appeared to have a longer duration of action. The side-effects produced by the two drugs were similar, as were the effect o…

1. Methodological reasons are discussed which make placebo-controlled trials on antidepressant drugs necessary. 2. The ethical problem of treating a sick patient with an inactive compound are shown to have an impact on the methodology of such trials. 3. Three double-blind placebo-controlled trials with nomifensine are…

In type II A hyperlipoproteinaemia, treatment with cholestyramine (12 g), calcium clofibrate (2 g) and a combination of calcium clofibrate and calcium carbonate (2 + 2 g) reduced the cholesterol concentration. The combination of calcium and clofibrate was at least as effective as cholestyramine. Calcium clofibrate decr…

The gastrointestinal blood loss during intake of two ampicillin esters (pivampicillin and bacampicillin) was studied in 10 male volunteers. A radioactive chromium method was used. The study was performed with a double-blind cross-over technique. Pivampicillin seemed to give a slightly higher increase in gastrointestina…

A double-blind controlled trial of oral zinc sulphate as adjuvant treatment in idiopathic ulcerative colitis or proctitis in relapse is reported. Fifty-one patients were treated, and the clinical and sigmoidoscopic improvement in the zinc treated patients was similar to that in patients receiving placebo. No difference…

A double-blind prospective study was carried out comparing the prophylactic effect of maprotiline and lithium carbonate over a period of 1 year in patients suffering from recurrent affective disorders. The average Affective Morbidity Index was lower, but not significantly so, in patients treated with lithium. A further…

A controlled trial of intraperitoneal noxytiolin (Noxiflex) solution in patients with peritonitis due to perforated appendicitis is reported. No significant difference was found in the incidence of complications between the treated and a control group, raising doubts as to whether this substance is of value when used i…

1 Inhaled salmefamol, in doses of 100 mug and 200 mug has been compared with inhaled salbutamol, in a dose of 200 mug, and with placebo in patients with airways obstruction. 2 Both salmefamol and salbutamol are potent bronchodilators with a signficantly superior action over placebo at all times up to 8 h after treatmen…

Twenty-three patients with rheumatoid arthritis participated in a double-blind crossover investigation of ketoprofen (Orudis) and indomethacin. Ratings which assessed the degree of joint involvement showed consistently greater improvement with Orudis, and side-effects occurred with less frequency. The majority of patie…

We remain convinced that antilymphocyte globulin (ALG) is a potent immunosuppressive agent in humans. For that reason, we have used it in essentially every case of renal transplantation since May of 1966; now, however, we are about to embark on a controlled clinical trial of ALG in kidney transplantation and await with…

13 psychotic patients developing various degrees of postural hypotension during neuroleptic or antidepressant treatment were additionally given either placebo or a mineralocorticoid or a sympathomimetic drug. As shown by Schellong tests during therapy the best effect on postural hypotension was achieved by the mineralo…
