Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
An increased loading dose of ondansetron: a north european, double-blind randomised study in children, comparing 5 mg/m2 with 10 mg/m2.
A North European, randomised, double-blind study, comparing a loading-dose of ondansetron of 5 mg/m2 with 10 mg/m2, administered intravenously before highly emetogenic chemotherapy, was carried out in 187 chemotherapy-naïve children. In the first 24 h, both groups received further ondansetron intravenously at a dose of 5 mg/m2 8-hourly. Thereafter, ondansetron was given at an oral dose of 4 or 8 mg depending on the surface area of the child, three times a day and continued for at least 3 days after the last day of chemotherapy. ⋯ Ondansetron provided good control of emesis and nausea on day 1 with 71-72% of patients experiencing two or fewer emetic episodes (complete or major responders) and 90-86% of patients reporting nausea as none or mild. There was also no difference in the efficacy of the treatment arms in the control of emesis and nausea on subsequent days of the study period. Both anti-emetic regimens were well-tolerated.

The aim of this prospective study was to investigate associations of mammography pain and discomfort with sociodemographics, personal history and psychological and situational factors. Subjects were women with a negative screening finding (n = 883) from a random sample of 50-year-old Finnish women attending their first breast cancer screening. Questionnaires were sent 1 month before the screening invitation and 2 months after screening. ⋯ Linear regression analyses showed that anticipation of pain and discomfort was the most powerful factor explaining pain and discomfort among women with earlier mammography. However, it had no effect among women without earlier mammography, for whom screening-related nervousness and perceptions of staff were crucial. Suggested interventions include better information before screening, a friendly screening atmosphere and empathetic, supportive staff behaviour, especially towards women having their first mammogram, encouraging them to feel more at ease and distracted from pain.
