Ionic contrast media currently used in cerebral angiography frequently cause discomfort due to hyperosmolality. This double-blind, multicenter trial compared two ionic media, meglumine iothalamate and meglumine-Na diatrizoate, with the new nonionic agent, iohexol, in 277 patients undergoing cerebral angiography. Vital…

Patients with glaucoma received either 3% guanethidine-0.5% epinephrine (20 patients) or 1% guanethidine-0.2% epinephrine (20 patients) and then 0.5% timolol maleate. The fall in intraocular pressure during 3% guanethidine-0.5% epinephrine therapy (10.1 mm Hg [34.4%] reduction) was higher than during timolol therapy (7…

Following a nationwide outbreak of Shigella dysentery type 1 and the recognition of Shigella isolates resistant to ampicillin, the drug of choice, we conducted a clinical trial to compare the efficacy of ampicillin v. trimethoprim-sulphamethoxazole for the treatment of Shigella dysentery. Patients with symptoms of dyse…

An open-label clinical trial was conducted to test the safety and efficacy of intravenous metoclopramide monohydrochloride in preventing chemotherapy-induced nausea and vomiting. Thirty-eight patients received a total of 83 assessable courses of chemotherapy with cisplatin alone or in combination with other cytotoxic a…

One hundred anaesthetics were administered in a clinical trial to 95 equine patients, ranging in age from nine months to 19 years and in weight from 140 to 1270 kg, undergoing a variety of surgical procedures. Acepromazine maleate premedication (0.01 to 0.03 mg per kg intramuscularly) was given to seven animals, the re…

A clinical trial comparing Bleomycin (BLM) plus radiation against radiation alone is reported. One hundred and fifty-seven previously untreated T3 and T4 and N0, N1 or N2 buccal squamous cell carcinomas were entered. Eighty-four of these received the combined therapy and 73 were controls. Cobalt-60 teletherapy using tw…

We studied 16 patients with long-standing irritable bowel syndrome of moderate severity using a controlled, double-blind crossover method. Five sedative-anticholinergic drug combinations and a placebo were tested. The subjective response was assessed with four subjective methods to include an increasing number of respo…

Fifty consecutive patients with colorectal cancer but no evidence of secondary deposits in the liver were included in an ongoing controlled clinical trial of adjuvant liver perfusion aimed at reducing the incidence of hepatic metastases. All patients had their primary tumour resected in the standard way. Twenty-six of…

In the present paper we studied the clinical effects of psychotropic drugs. In the experimental part we studied their effects on our patients and normal subjects and compared it with the results obtained with the placebo treatment. We studied the effect on attention (A), efficiency (E) psychomotor rate (PR), numerical…

In a combined clinical trial with gold in patients with rheumatoid arthritis (RA) 95 patients were treated with a high initial dosage of 2,500 mg aurothioglucose in 21 weeks. Afterwards 48 of these patients received a maintenance dosage of gold and 47 patients placebo injections. Another group of 101 patients received…

The quantitative analysis of magnetic resonance imaging (MRI) data has become increasingly important in both research and clinical studies aiming at human brain development, function, and pathology. Inevitably, the role of quantitative image analysis in the evaluation of drug therapy will increase, driven in part by re…

In a double-blind clinical trial comprising 29 depressed patients citalopram, a highly selective 5-HT re-uptake inhibitor and maprotiline, a specific NA re-uptake inhibitor, were compared. Allowing for the small sample and taking into consideration that both groups consisted of severely ill, hospitalized patients, it i…

Transcatheter aortic valve replacement (TAVR) has revolutionized the treatment of severe aortic stenosis, yet paravalvular leakage (PVL) remains a significant complication, associated with increased mortality. Clinical studies have identified correlations between PVL and both anatomical features and calcification patte…

PURPOSE: Pediatric Rhabdomyosarcoma (RMS) is a morbid and often lethal condition characterized by a paucity of clinical data. Beyond a detailed risk categorization system, it is unclear if genitourinary (GU) sites (bladder/prostate, paratesticular, female organs) have outcomes distinct from non-GU sites. This study poo…
