In adults the calcium antagonist amlodipine given once a day has proved to be an attractive addition to the antihypertensive armamentarium. The present report describes our experience in 43 paediatric outpatients (26 boys and 17 girls, aged between 1.1 and 19, median 9.8 years) with chronic kidney diseases. The patients were given amlodipine for 16 weeks as part of their antihypertensive treatment. Before amlodipine arterial pressure was 150 (142-163)/90 (84 -95) mm Hg (median and interquartile range). Six patients withdrew from amlodipine because of oedema, flushing or headache. In the remaining patients amlodipine 7.7 (6.9-9.4) mg/m 2 body surface area once a day significantly decreased arterial pressure by 17 (13-22)/10 (7-13) mm Hg. The

In this survey infections were found as a definite or at least presumptive trigger of erythema multiforme in 71% of cases. Drugs (including immunization) implicated as triggers of erythema multiforme played a definite causative role in 10% and a presumptive role in a further 29% of patients. In 19% of patients an associated condition was not diagnosed.
