Twenty-seven patients with tennis elbow were treated with triamcinolone acetonide (40 mg/ml) injected locally into the tender area without local anaesthetic. Reduction of pain or complete relief was achieved in 1 to 72 hours, although in 9 cases exacerbation of pain occurred before relief was given. The recurrence rate at 6 months was 17.8%. The study shows that triamcinolone acetonide is a useful preparation in the relief of this condition.

A single dose of 2g cephradine was administered intravenously at the time of anaesthetic induction to 20 patients with occlusive arterial disease. Concentrations of cephradine were measured in serum, subcutaneous fat from the groins of 10 patients underdoing arterial reconstruction and in the subcutaneous fat and skeletal muscle of 10 legs amputated for severe arterial ischaemia. Concentrations of cephradine were adequate for antibacterial prophylaxis at the time of operation in all serum samples, 9 out of 10 samples of subcutaneous fat from reconstruction cases, all muscle and 8 of 10 fat samples from the level of section of amputated limbs, and in 8 of 10 muscle and fat samples from the distal parts of amputated limbs. These results confirm that a single intravenous dose of 2 g cephradine given with anaesthetic provides adequate serum and tissue concentrations for antibacterial prophylaxis during vascular surgery.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparative study of haloperidol and diazepam in the treatment of anxiety.
In a single-blind study in general practice, 60 patients with anxiety neuroses were randomly allocated to receive either 0.5 mg haloperidol twice daily or 2 mg diazepam 3-times daily for 6 weeks. Eighteen patients (6 on haloperidol and 12 on diazepam) were excluded from the analysis of efficacy. On the Hamilton Rating Scale both haloperidol and diazepam reduced the anxiety and depression scores. ⋯ After 6 weeks, 93% of patients felt 'better' or 'much better' on haloperidol, compared with 83% on diazepam. A few, minor side-effects were reported, slightly fewer on haloperidol than on diazepam. In the parameters tested in this study, haloperidol has been shown to be more effective than diazepam in the treatment of anxiety neuroses and appears to provide significantly better overall symptomatic relief and to be more acceptable to patients than diazepam.

Clinical Trial
The penetrability of cephazolin into the subcutaneous fat and skeletal muscle of ischaemic lower limbs with atherosclerotic disease.
Seventeen patients with atherosclerotic disease, who were undergoing arterial reconstruction or amputation of the lower limb, had 2 g cephazolin injected per-operatively in two equal doses by intramuscular and intravenous routes. Samples of subcutaneous fat and skeletal muscle from the ischaemic leg, and serum were collected during the operation for assay of cephazolin content. The mean cephazolin levels in the serum, skeletal muscle and subcutaneous fat were found to be well above the minimum inhibitory concentrations required for most important Gram-positive and Gram-negative pathogens.

Randomized Controlled Trial Comparative Study Clinical Trial Controlled Clinical Trial
A double-blind comparison of nefopam and placebo in post-operative pain.
Nefopam (90 mg), an analgesic, was compared with placebo in a double-blind trial in patients who had undergone total abdominal hysterectomy operations. Analgesic activity was assessed by patients rating their pain before and 1 hour after administration of each treatment, by sequential analysis of patient and observer preference for treatment, and by calculation of the time interval between doses of the two treatments. Nefopam was found by observer preference to be significantly better than placebo in relieving post-operative pain. In patients with severe initial pain, the time between doses after nefopam was significantly longer than after placebo.
