Multicenter Study Clinical Trial
An open multicentre study of tropisetron for cisplatin-induced nausea and vomiting.
(i) To assess the efficacy and tolerability of tropisetron when used for acute and delayed cisplatin-induced emesis. (ii) To investigate whether dexamethasone added to tropisetron improves the control of emesis for patients who do not achieve a complete response to tropisetron alone. (iii) To assess sex of the patient and alcohol intake as prognostic factors for nausea and vomiting. ⋯ Tropisetron was effective for acute cisplatin-induced emesis; adding dexamethasone enhanced this response. Both single and combined therapy had less effect on delayed emesis. The impact of alcohol on control of emesis is a chronic rather than acute phenomenon which requires prospective testing.

Could focused population screening detect osteoporosis earlier and improve the management of this major health care problem? Quantitative ultrasound of the calcaneus is currently being proposed as a suitable screening technique. Correlations between quantitative ultrasound of the calcaneus and dual energy x-ray absorptiometry of bone mineral density of the spine and proximal femur are not high enough to reliably predict bone mineral density at the lumbar spine or proximal femur from the ultrasound results. Some ongoing longitudinal studies suggest that quantitative ultrasound may none the less detect individuals at increased risk of fracture, but its use for mass screening for osteoporosis would be premature.
