A new dressing for chronic wounds, BioFilm hydrogel dressing, was compared to a hydrocolloid dressing (HCD) control in a clinical trial involving 90 patients and 129 Stage I and II wounds (defined by Enis and Sarmienti). The testing sites included both acute care and extended care facilities. A comparison of healing re…

A double-blind, five phase, cross-over clinical trial was used to compare a mucin-based artificial saliva (Saliva Orthana) with its non-mucin base and water. Thirty patients, acting as their own controls, took part. Saliva Orthana offered significantly greater relief from xerostomia compared with its base or water, and…

One of the objectives of randomization is to balance the number of patients in each level and combination of levels of prognostic factors. However, as the number of possible prognostic factors increases, some imbalance may occur and make the results of the analysis less interpretable. In order to balance the marginal d…

Authors report a prospective clinical an bacteriological study in 32 patients, almost with a chronic bronchopulmonary disease. A group of 16 patients was treated with the association clavulanic acid-amoxicillin (ACA) and the 16 others with josamycin (J) for an acute exacerbation of bronchitis. Pus and numeration of bac…

An open clinical trial was conducted on an unlocked ward investigating the use of benzodiazepines as adjunctive therapy with neuroleptics in managing acute exacerbation of chronic schizophrenia. Seventeen patients meeting DSM-III criteria for this disorder were treated. Patient response was monitored with use of the Br…

It is to be expected that in the near future the success or failure of antihypertensive substances will be mainly determined by their spectrum of side effects so long as their antihypertensive efficacy is comparable. This double-blind study with crossover of enalapril and atenolol in 58 mild to moderate hypertensive pa…

One hundred five patients with MS were divided into three groups matched for age, sex, and disability, and treated with either placebo, transfer factor prepared from leukocytes of random donors, or transfer factor from leukocytes of family members living with the patients. There were no differences in the three treatme…

A new disposable bleeding time device (Hemalet) was tested in 20 normal individuals and 11 patients with various bleeding disorders. The results were compared with those of Simplate II. The mean bleeding time for normal individuals was 5.4 +/- 1.5 (mean +/- 1 SD) minutes by Hemalet and 5.8 +/- 1.4 (mean +/- 1 SD) minut…

The International Mexiletine and Placebo Antiarrhythmic Coronary Trial (IMPACT) included clinical centers in both Europe and North America. The clinics were monitored by two Regional Coordinating Centers: one located in Baltimore, Maryland, for North American clinics; the other in Lyon, France, for European clinics. Th…

Twenty patients with moderate to very severe painful menstrual periods secondary to endometriosis were treated in a double-blind, four-period, crossover clinical trial with naproxen sodium and placebo. Complete or substantial pain relief was obtained in 83% of the cases of painful menstruation with naproxen sodium and…

Twenty two patients were entered into a randomised controlled clinical trial comparing the efficacy of somatostatin and vasopressin in controlling acute variceal haemorrhage. Somatostatin was significantly more successful in controlling acute variceal haemorrhage than vasopressin (p = 0.003). Furthermore, no complicati…

The first clinical trial with the non-ionic contrast medium iohexol (Omnipaque) in lumbar myelography was performed as a multicentre investigation of a total of 88 included patients. The design of the comprehensive clinical trial program is presented and the necessity of using such an extensive clinical trial program i…

A double-masked controlled clinical trial of 5% unpreserved tolmetin versus 0.5% prednisolone versus 0.9% saline in acute endogenous nongranulomatous anterior uveitis was carried out on 100 patients. 69% of the prednisolone-treated patients were judged "cured" at the end of the 3-week study. This is compared with a cur…

Using spirometry, the effects on lung function of interposing a tube extension between a bronchodilator aerosol (terbutaline sulphate 0.25 mg) and the mouth and an ordinary aerosol have been compared. Both devices were administered with a delay of 2 s from actuating the aerosol to inhalation, thus simulating inability…

A double-blind cross-over trial of timolol maleate (Timoptol) while routine medical therapy was continued gave the result that pressure was reduced by 3.22 mmHg is compared to placebo and 5.01 compared to pre-timolol levels in 24 patients. There was also a small (1.858 mmHg) drop in pressure in placebo treated eyes, a…

A ten-week, double-masked, randomized, clinical trial compared timolol ophthalmic solution and pilocarpine in the therapy of open-angle glaucoma. Timolol decreased the intraocular pressure at least as much as pilocarpine and did not induce miosis, accommodative spasm, or other annoying side effects. The pulse was slowe…

A double blind clinical trial was conducted in which both the plaque-inhibiting ability and the in vivo effects on the oral flora of chlorhexidine and picloxydine mouthwashes was compared. While picloxydine in higher concentration suppressed the oral flora more effectively than chlorhexidine, the latter agent inhibited…

A double-blind between-group trial was carried out in 50 depressed patients to compare the efficacy of two sustained release forms of amitriptyline--Lentizol and Tryptizol 75. Patients received either Lentizol 50 mg or Tryptizol 75 75 mg each evening for the first week of the trial, and these dosages were then doubled…
