Randomized Controlled Trial Clinical Trial
Controlled trial of an elbow support ('Epitrain') in patients with acute painful conditions of the elbow: a pilot study.
A randomized, controlled, parallel-group study was undertaken to assess the clinical efficacy of a new elbow support ('Epitrain') compared with a standard elasticated tubular stockinette support ('Tubigrip') in 35 patients with acute painful elbow disorders. On entry, patients had a clinical examination, including measurement of the range of active and passive movement of the affected joint, and were allocated to one or other treatment group (19 to 'Epitrain', 16 to control). All patients were allowed to take 1g paracetamol up to 4-times daily if necessary for the control of pain. ⋯ The mean range of active joint movement improved from 80 degrees to 141 degrees in the 'Epitrain' group, but only from 83 degrees to 98 degrees in the control group (p less than 0.0002). Similar results were obtained for passive joint movement. Overall, 13 (68%) of the 19 patients in the 'Epitrain' group were described as 'cured' as compared with 2 (13%) of the 16 patients in the control group (p less than 0.02).(ABSTRACT TRUNCATED AT 400 WORDS)

Randomized Controlled Trial Clinical Trial
Double-blind, placebo-controlled clinical trial of a mixture of gangliosides ('Cronassial') in post-herpetic neuralgia.
A double-blind, parallel-group clinical trial was carried out in 25 patients with post-herpetic neuralgia to determine the efficacy and tolerability of a mixture of gangliosides ('Cronassial') compared with placebo. Patients were allocated at random to receive treatment with either 'Cronassial' (100 mg in 2 ml buffered solution) or placebo given by 11 subcutaneous injections over a period of 27 days, and their symptoms assessed on entry and after 2, 4 and 8 weeks. The four aspects of pain considered (overall pain, hyperaesthesia, stabbing pain and constant ache) all showed maintained reductions in severity with 'Cronassial' treatment, but not with placebo. ⋯ Two of these 5 patients were withdrawn from the study. There were no withdrawals in the placebo group. It is suggested that further studies employing greater numbers of patients should be carried out to confirm the efficacy of gangliosides in improving symptoms of patients with post-herpetic neuralgia.

Randomized Controlled Trial Clinical Trial
Etizolam versus placebo in the treatment of panic disorder with agoraphobia: a double-blind study.
Thirty out-patients suffering from panic disorders associated with agoraphobia were enrolled in a double-blind, controlled trial to compare the effectiveness and tolerability of etizolam and placebo. After a 1-week washout period on placebo, patients were allocated at random to receive twice daily doses of either 0.5 mg etizolam or placebo over a period of 4 weeks. ⋯ The results showed that etizolam produced significant improvements in chronic anxiety, phobic ideas, associated depressive symptoms and episodic anxiety, and was significantly more effective than placebo. Etizolam treatment was generally well tolerated and was not significantly different from placebo in this respect.

Randomized Controlled Trial Comparative Study Clinical Trial
Etizolam in the treatment of generalized anxiety disorder associated with depressive symptoms.
A double-blind study was carried out in 30 female patients with generalized anxiety disorders associated with depressive symptoms to compare the effectiveness and tolerability of etizolam and alprazolam. Patients were allocated at random to receive one or other drug at a dosage of 0.5 mg twice daily for 5 weeks. ⋯ Although there was no statistically significant difference between the two drugs, there was a trend for etizolam to be more effective in relieving anxiety somatization symptoms. Apart from moderate daytime drowsiness in a few patients, both drugs were considered to be extremely well tolerated.

Comparative Study
Metformin efficacy and tolerance in obese non-insulin dependent diabetics: a comparison of two dosage schedules.
A comparative open study of metformin unit doses of 500 mg and 850 mg was carried out in 64 obese, non-insulin dependent diabetics on 1.5 to 3 g metformin daily. Glycaemic response, blood lactate, plasma metformin concentrations and tolerance for metformin were assessed. ⋯ Seven patients (3 asymptomatic and 4 with background symptoms) became intolerant of the 850 mg regimen and required to return to the 500 mg dose regimen. After exclusion of patients intolerant of the 850 mg dose regimen (11%), the remaining patients noted no significant change in symptoms and 28% of all patients transferred to the 850 mg dose unit indicated an overall preference for this regimen.
