We report on the first decade of the helium-ion radiotherapy clinical trial being carried out at the Lawrence Berkeley Laboratory. Over 500 patients have now been treated. We have had very good results to date in treating patients with small tumors critically located near a radiation-sensitive organ which would preclud…

The effect of cimetidine (1 g daily) and placebo was studied in a controlled clinical trial comprising 50 patients with non-ulcer dyspepsia in whom an organic abnormality responsible for the dyspeptic symptoms was not disclosed by a standardized and extensive examination programme. Reduction of symptoms occurred in 13…

Iohexol, a new nonionic contrast agent, and Conray 60 were compared in a double-blind clinical trial of 60 patients for safety, imaging effectiveness, and patient discomfort in cerebral angiography. There was no significant difference between the two agents in physiologic changes, film quality, or incidence of adverse…

Two hundred patients in a major Indian hospital who were undergoing clean operations participated in a prospective, randomised, controlled clinical trial of the effectiveness of systemic antibiotics in preventing wound infectious. Of the patients on antibiotics 12.6% developed wound infections and of those not on antib…

Our experience with hypoglycemia during a randomized clinical trial testing the hypothesis of a causal relationship between hyperglycemia and diabetic complications is described. Patients under maximized control experienced hypoglycemia much more often than patients under standard control. There were five episodes of s…

A controlled clinical trial was conducted to compare the value of a cream containing 2% phenoxetol and 0.2% chlorhexidine as a prophylactic agent against wound infection in patients with burns affecting up to 15% total body surface area. The acquisition of bacteria was similar in the two treatment groups but the incide…

Fentiazac 5% cream was applied topically on limited articular and extra-articular inflammatory lesions in the course of a double-blind clinical trial versus placebo. The drug proved to be satisfactorily tolerated and also therapeutically effective since it changed significantly (p less than 0.05--less than 0.01) the sp…

Cimetidine prophylaxis significantly reduced the risk of gastrointestinal bleeding after severe head injury in this prospective, double-blind clinical trial. Cimetidine effectively reduced both the volume and the acidity of gastric secretions after brain injury without producing adverse side effects. The most common en…

In a prospective randomized clinical trial, whole gut lavage was evaluated against conventional mechanical cleansing for colonic operations. The lavage took less time to perform, was better tolerated by patients, and resulted in more satisfactory preparation as judged by frequency of collapsed intestines. There was no…

The effect of intravenous lidocaine in the treatment of persistent cough occurring after diagnostic bronchoscopies performed under general anaesthesia was investigated in a controlled clinical trial. The study comprised 28 adults patients, all of whom had regained consciousness after anaesthesia. Fifteen patients were…

Riluzole, a benzothiazole sodium channel blocker that received US Food and Drug Administration approval to attenuate neurodegeneration in amyotrophic lateral sclerosis in 1995, was found to be safe and potentially efficacious in a spinal cord injury (SCI) population, as evident in a phase I clinical trial. The acute an…

Increased age and female gender are well-known risk factors for the development of desmopressin-induced hyponatremia. However, little focus has been on exploring gender differences in the antidiuretic response to desmopressin. Based on an exploratory analysis from three clinical trials, we report a significant gender d…

Clofarabine is a deoxyadenosine analog synthesized with the intention of retaining the favorable mechanistic properties of fludarabine and cladribine while eliminating their undesirable characteristics. Phase I studies among 32 patients with acute leukemia defined a maximum tolerated dose (MTD) of 40 mg/m2/d given as a…

We evaluated the effect of vibratory stimulation on 10 patients with tinnitus and controlled it in a double-blind crossover trial against the sound stimulus delivered by the same apparatus. Five patients reported decreased intensity of tinnitus during treatment when vibratory stimulation was used, as opposed to 1 patie…

A double-blind trial demonstrates the effectiveness of adding hyaluronidase to lignocaine with adrenaline in producing ocular akinesia and anaesthesia in retrobulbar nerve blocks. 92% of the blocks in which hyaluronidase was used for intracapsular cataract surgery were judged successful compared with 56% of those witho…
