The effect of eflornithine 13.9% cream on the bother and discomfort due to hirsutism.

Although unwanted facial hair often leads to anxiety and avoidance of social situations, evaluation of treatment outcomes in clinical trials has relied largely on measures external to the patient such as the extent of hair growth or an expert physician's assessment, neglecting to include patient reported outcomes (PRO). To assess the level of bother caused by a dermatological condition (hirsutism) and changes brought on by treatment, the instrument ESTEEM was developed by expanding the Bother Assessment in Skin Conditions (BASC) scale to six questions to cover the discomfort felt in four social situations and bother due to removing facial hair. Each question elicits responses on a visual analog scale. Women participating in two randomized clinical trials evaluated a new treatment (eflornithine 13.9% cream). Analyses examined the level of bother at each visit, the changes with treatment, the correlations with the Physician's Global Assessment, and the effect size. Hirsutism bothers patients considerably. The mean for overall bother was 89% and the mean discomfort in social situations exceeded 80% in nearly all cases. Treatment led to significant reductions in bother on all six items with effect sizes ranging from 0.46 to 1.62. Eflornithine is an effective treatment for unwanted facial hair in women, as reported by the patients. ESTEEM addresses the specific concerns of women with hirsutism.

Instituting a routine varicella vaccination program in Canada: an economic evaluation.

BACKGROUND: After licensing of a varicella vaccine in Canada in 1998, Health Canada commissioned a study to evaluate options for a vaccination program. The evaluation of a program of vaccination of 12-month-old children, with and without a catch-up program for susceptible 12-year-olds, is presented here. METHODS: An economic model was developed simulating the expected experience, with and without vaccination, of cohorts of children susceptible to varicella. The cohorts were simulated for 70 years, and infection and complication rates were calculated along with the attendant costs, with an assumed vaccine cost of $60. RESULTS: With an 85% coverage rate vaccination is expected to reduce the number of chickenpox cases by approximately two-thirds and varicella-related complications by up to 75%. The overall costs of varicella are expected to drop by >$4 million (1998 Canadian dollars) per 100,000 eligible vaccinees, but costs to the health care system are expected to increase by >$2 million. From the health care system perspective, vaccination would cost approximately $42 per discounted case avoided. INTERPRETATION: Routine varicella vaccination would likely substantially reduce the overall costs of managing chickenpox but would result in an increase in health care expenditures. These findings are consistent with evaluations in other countries.
