Longer term effects of live influenza vaccine in patients with chronic pulmonary disease.
WRL 105 strain live influenza vaccine or placebo was given to patients with chronic bronchitis in a double-blind study. The twenty-one vaccinated and twenty-three placebo-treated patients made daily self-assessments of the severity of symptoms of cough, breathlessness, tightness, wheeze, and sputum production in the following 20 weeks. Symptom scores in the first 2 weeks after vaccination or treatment with placebo were used to calculate a baseline range for each patient. Comparison of symptoms in the two groups in the baseline period showed that symptoms were more often reported by vaccinated than by placebo-treated patients but the differences were not statistically significant. One patient who responded serologically to vaccination had a moderately severe influenzal illness starting on the day after vaccination. Comparison of symptom scores during the 18-week surveillance period with baseline values showed that symptoms of breathlessness, tightness, wheeze and cough were significantly more common in vaccinated than in placebo-treated patients and that antibiotic usage was more common in the vaccinated group.

Pharmacokinetics--uses and abuses.
It is apparent from studying recent articles on pharmacokinetics that a number of misunderstandings exist, both about the design of experiments and the analysis of results. The purpose of this paper is to outline many of the common pitfalls associated with the design of experiments and also the limitations upon the analysis of results. The paper describes mathematical, laboratory and clinical aspects which must be examined in designing a protocol for pharmacokinetic experiments. Simulated data is presented to demonstrate the dangers of using standard computer programs for parameter estimation. Even when convergence is obtained the answers may be dependent on the method employed. A mathematical model is of little use unless a reasonable amount of good, accurate data is obtained.
