In a double blind trial, 25 patients with twin pregnancy were given 40 mg of ritodrine hydrochloride by mouth daily and 24 similar patients received a placebo. The ritodrine group had no significant prolongation of pregnancy nor increase in birth weight, and a high incidence of side effects occurred.

Thirty-two patients were treated with placebo tablets or indomethacin (25 mg three times daily) in a six-month, double-blind, cross-over trial. During indomethacin therapy, 75 per cent of patients experienced significant pain relief while associated vomiting and diarrhoea were relieved in 44 per cent and 64 per cent of…

The efficacy of 3 g of amoxicillin plus 1 g of probenecid was compared with the efficacy of 3.5 g of ampicillin plus 1 g of probenecid for the treatment of uncomplicated gonorrhea. In a clinical trial no therapeutic failure was seen among 60 patients who were treated with the former regimen. The combination of ampicill…

In 38 obese maturity-onset diabetic patients the effect of fenfluramine therapy on carbohydrate tolerance was compared to placebo therapy in a double blind trial. Fenfluramine therapy did not affect weight loss, or fasting glucose levels but produced a slight but significant improvement in glucose tolerance. This impro…

Enteritis necroticans remains a serious problem in the Highlands of Papua New Guinea. Earlier claims that Clostridium Welchii Type C antitoxin is effective in lowering mortality rates were subjected to a prospective controlled trial in 1972-73.

The results of the study on the pharmacokinetics peculiar properties of carbenicillin premature infants treated with the drug administered intravenously or intramuscularly are presented. The maximum antibiotic blood levels after intravenous administration exceeded the MIC for most of the causative agents isolated from…

Arecholine (4 milligrams), a cholinergic agonist, and choline (10 grams), a precursor of acetylcholine, significantly enhanced serial learning in normal human subjects. The subjects received methscopolamine prior to both arecholine and placebo injections. Conversely, scopolamine (0.5 milligram), a cholinergic antagonis…

A total of 100 patients were examined by both single and double contrast upper gastrointestinal radiography. The radiographs were coded, interpreted blindly by two gastrointestinal radiologists, and the accuracy of each examination was determined using endoscopy as the standard. The interpretation error rate for each t…

The efficacy of gold salt on bronchial asthma was investigated by double-blind design in 79 patients. The rate of improvement was significantly higher in the gold-treated group (20/28) than in the controls (16/36). This was reflected by greater reduction of requirement for symptomatic medications. Only mild side effect…

Dementia is a symptom complex probably arising from cerebral metabolic insufficiency. The testing of drugs thought to improve cerebral metabolism is difficult and many problems have to be overcome. Assessment of brain failure requires objective tests of intellect and memory. Subjective tests are used for disorders of p…

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…

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…

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…
