This preliminary study compared placebo with diclofenac (50 mg, rising to 150 mg per day) in a crossover study for seven days in thirteen inpatients. Regardless of the marked overall effect of hospitalization, an additional effect of diclofenac on grip strength and p.i.p. joint swelling was demonstrated, as well as a s…

Forty patients who were suffering from chronic dyspepsia, diagnosed clinically and radiologically as being related to delayed gastric emptying, were treated with either domperidone or placebo in a double-blind trial. The trial lasted four weeks and the dose of domperidone was 10 mg orally t.d.s. before meals. The resul…

Fenoterol is a beta 2-sympathomimetic bronchodilator. In a double-blind cross-over trial in 17 asthmatic patients with reversible airway obstruction inhalation of both fenoterol (0.4 mg) and terbutaline (0.5 mg) produced a statistically significant greater increase in peak expiratory flow rate than did placebo. The mag…

A prospective double-blind study of the effect of hyaluronidase on aphakic cystoid macular edema (CME) was performed. A 25% incidence of CME was encountered in patients receiving hyaluronidase admixed with the local anesthetic while no cases were diagnosed in the group not receiving hyaluronidase. The role of hyaluroni…

In a short-term (over 4 weeks) clinico-microbiological study on 18 Soviet school children, 12 years of age, it was found that a supervised oral hygiene action with the amine fluoride-containing caries-preventing agents Silca and Elmex fluid (produced in the GDR) had resulted in a marked reduction in plaque formation, a…

The research methodology of 78 double-blind studies comparing benzodiazepines and placebo in treating neurotic anxiety is critically reviewed. Many faults are noted in areas of subject selection, assessment of clinical response, study design and data analysis. Although 56.4% of the studies reviewed had results demonstr…

Xipamide (4-chloro-5-sulphamyl-salicylic acid 2', 6'-dimethylanilide) is a diuretic and antihypertensive agent. A clinical trial of the drug was performed in 11 patients, 8 with nephrotic syndrome, 1 with oedema and ascites due to hepatic cirrhosis, and 2 with congestive cardiac failure due to idiopathic cardiomyopathy…

Deanol and placebo were administered to 10 parkinsonian patients with levodopa-induced dyskinesias in a double-blind, crossover fashion. Deanol and placebo did not differ significantly in their effects on dyskinesias. The reported properties of deanol seem to be attributable to a placebo effect. There was no correlatio…

A double-blind controlled study of 14 preschool children with recurrent wheezing episodes was performed to show the effectiveness of nebulised sodium cromoglycate in inhibiting exercise-induced bronchoconstriction in this age group. All 14 children showed markedly less exercise-induced bronchoconstruction after nebulis…

An ammonium ion-specific electrode system is evaluated for analysis of blood urea nitrogen from serum, plasma ultrafiltrate, or hemodialyzer dialysate fluid. The electrode shows a high sensitivity over clinically useful concentration ranges. Free serum ammonia, volatile amines, or urea ammonia after hydrolysis can be m…

Symptomatic therapy in Sydenham's chorea has not been satisfactory. Perphenazine was tested as an alternative to diminish abnormal movements. A Syndenham's chorea comparative double-blind study (17 patients) using it, with reserpine and placebo as controls, was designed. Perphenazine was tried also in another open-stud…

The effect of metabolite VIII of bromhexine on surfactant content in the amniotic fluid was investigated in a double blind study. Administration of 100 and 200 mg NA-872 daily for 5 days to pregnant women ranging in gestational age from 196 to 243 days was not followed by a significant rise in the L/S ratio.

Twelve highly selected patients with non-arteriosclerotic cardiac arrhythmias and/or chest pain refractory to medication and having symptoms related to smooth muscle sensitization were studied in a rigidly controlled, relatively fume- and particle-free environment. The majority of signs and symptoms cleared in 10 patie…

In 30 human subjects, experimental pain was produced by either ischemia or cold-water immersion. In a double-blind procedure, intravenous doses of up to 10 milligrams of naloxone hydrochloride in saline were indistinguishable from similarly administered saline alone. There were no effects on subjective pain ratings, fi…

Eighty-seven per cent of surgical patients receiving undiluted diazepam experienced pain on injection while 6-16%, depending on the dose, manifested evidence of clinical thrombophlebitis. This was improved when diazepam, 10 mg, was diluted to 20-40 ml with intravenous solution. In contrast, lorazepam appeared to have m…

In order to achieve a more differentiated assessment of the profile and time course of treatment with a new antidepressant drug, several psychiatric, neurophysiological, and biochemical parameters were examined in a double-blind study (viloxazine versus amitriptyline). Special attention was directed to the use of a tim…

1. The hypotensive effect of methyldopa alone or associated with other hypotensive drugs was evaluated in 155 patients. After 10 days of treatment, the blood pressure was back to normal in 80% and in 50% of the patients with mild and moderate hypertension, and it was significantly decreased in those with severe hyperte…

In a double-blind trial of chlorpromazine and thiothixene conducted with 79 acutely ill, newly hospitalized schizophrenic patients, chlorpromazine and thiothixene were shown to be equally effective in producing meaningful symptomatic improvment over an average period of approximately 3 weeks, as measured by Global Asse…
