In contrast to the drug testing under clinical conditions, many other problems appear in regard to outpatients. These investigations were carried out on 49 outpatients with various degrees of angina pectoris under the conditions of an intraindividual comparison with d,l-oxyfedrine (Myofedrin), l-oxyfedrine (ildamen) or…

A controlled, double-blind trial on 42 children showed that a dentrifrice containing 0,25% fluorine clearly prevented caries when used continuously for 2 years. This effects was greater than that of a similar toothpaste containing fluorine. Tolerance was excellent.

Because of its better tolerance, sequential ultrafiltration and dialysis may be useful for intermittent fluid removal in dialysis patients. It offers no major clinical benefits as a chronic form of therapy and may be deleterious for some parameters.

The relief of pain after extraction of a mandibular third molar by two analgesics, rimazolium and acetylsalicylic acid (ASA) was studied in three groups of patients, who received either of these analgesics or a placebo. A questionnaire and careful instructions on its use were given to the patients. ASA had a better eff…

The final results of a clinical trial comparing endocrine with cytotoxic drug treatment for advanced breast cancer were analysed. Although cytotoxic treatment gave a significantly higher response rate with a remission duration comparable to that obtained with endocrine treatment, the sequence in which the two treatment…

In a randomized controlled clinical trial of hyperbaric oxygen in the radiotherapy of carcinoma of the bladder a total of 241 cases were contributed by four radiotherapy centres in the United Kingdom. In this trial where in each centre identical radiotherapy was employed for both oxygen and air cases, no benefit was sh…

The incidence of infections was studied in 137 iron-deficient Somali nomads, 67 of whom were treated with placebo and 71 with iron. Seven episodes of infection occurred in the placebo group and 36 in the group treated with iron; these 36 episodes included activation of pre-existing malaria, brucellosis, and tuberculosi…

The involuntary movements of Huntington disease may be related to cholinergic hypofunction in the striatum. For this reason, the effect of a direct cholinergic agonist, arecoline, was studied in six patients with this disorder. Rather than improving the chorea, arecoline tended to exacerbate the choreic movements. Arec…

A specialization of the biased coin clinical trial randomization schemes of Pocock and Simon (1975) and Efron (1971) is proposed which gives guidelines for the coin biasing probabilities of assignment to treatment. The scheme parameterizes the often conflicting goals of random treatment assignment and allocation for st…

Intravenous administration of glycerol under double-blind conditions (25 g twice daily for 6 days) to 26 patients with cerebral infarction localized in the territory of the middle cerebral artery temporarily improved the clinical evolution, as assessed by a scoring system, in comparison with 25 patients receiving place…

MK-231 (Sulindac), 200-400 mg daily, was given to 25 patients with rheumatoid arthritis. The therapeutic response was good and there were no side effects at all. The drug should be used more frequently than heretofore in the drug treatment of symptoms of rheumatoid arthritis.

Sixty subjects participated in a double-blind study comparing methadyl acetate (80 mg) with two dosages of methadone (50 mg and 100 mg) in the maintenance of opiate addicts. The safety of all three regimens was supported and methadyl acetate was as effective as methadone in the retention of subjects.

The effect of human leukocyte interferon on varicella-zoster infections was compared in a placebo controlled study. Thirty-six patients were treated with interferon and 26 with placebo. In the interferon treated group the duration of pain was shortened, the development of crust formation was enhanced and the viral clea…

A controlled clinical study of the effect of 1000 IU of calciferol daily for 8 months was performed on patients with postgastrectomy bone loss. The treatment produced no observable increase in bone mineral density measured by photon absorption.
