Prevention of delayed traumatic facial palsy.

A previous impression that corticotrophin provided prophylaxis against delayed traumatic facial palsy has now been confirmed by the results obtained from the first 50 patients so treated.

Does the fly matter? the CRACKPOT study in evidence based trout fishing. The Collaborative Randomised and Controlled Kennet Piscatorial Options Trail (CRACKPOT) Investigators.

OBJECTIVE: To investigate the importance of the type of dry fly (artificial floating fly) in catching trout (brown and rainbow) in an English chalkstream. SETTING: River Kennet, Berkshire. DESIGN: Five anglers on five separate occasions spent five hours using a randomly allocated fly from a sample of five types. PARTICIPANTS: Five anglers of considerable but varying experience, determination, and opinion. MAIN OUTCOME MEASURES: Number, weight, and species of trout caught. RESULTS: One fly (Black Gnat) performed significantly worse than the others. The fly most successful in catching brown trout was the Cinnamon Sedge. CONCLUSION: The possible prolongation of doctors' leisure time consequent on the use of unproductive trout flies has resource implications for the NHS. Urgent funding of a definitive, large multiriver trial is needed.

Protein energy supplements in unwell elderly patients--a randomized controlled trial.

BACKGROUND: To determine whether oral protein energy supplements, prescribed during hospitalization to elderly medical admissions, affect nutritional status and if baseline nutritional state influences this status. We also considered the effects on mortality, length of hospital stay, functional recovery, and institutionalization. METHODS: A prospective randomized controlled trial with no placebo. Consenting patients were stratified in 3 nutritional categories, and patients from each stratum were randomized into treatment or control. Observers were blinded to randomization. The participants were emergency admissions from home to a Medicine for the Elderly Unit in a Scottish hospital. The inclusion criteria were as follows: no known malignancy, the ability to swallow, and nonobesity (BMI < 75th percentile). The intervention was a prescription of 120 mL sip feed, 3 times daily (540 kcal, 22.5 g protein per day) throughout hospitalization, using the medicine prescription chart. The trial was powered to detect change in mean percentage weight. The following outcomes were also considered: anthropometry; mortality, length of hospital stay, functional recovery, and rates of institutionalization. RESULTS: Included in the trial were 381 patients. Nutritional supplementation was associated with significantly better energy intake (p = .001) and weight gain (p = .003) pooled across all nutritional categories. In the most poorly nourished patients, the intervention was associated with reduced mortality (5/34 versus 14/40, p < .05) and more patients improved functionally (17/25 versus 11/28, p < .04). Overall mortality results were 21/186 versus 33/195, odds ratio (OR) 0.62, 95% confidence interval (CI) 0.35, 1.13. CONCLUSIONS: Prescribing sip feed supplements in the medicine prescription chart during hospital stay reduces weight loss. Our data also support other evidence for a reduction in mortality noted in elderly patients on nutritional supplementation. There were suggestions of other clinical benefits.
