JF Archives of Disease in Childhood JO Arch Dis Child FD BMJ Publishing Group Ltd and Royal College of Paediatrics and Child Health SP 511 OP 513 DO 10.1136/adc.53.6.511 VO 53 IS 6 A1 T Karpathios A1 P Nicolaidou A1 A Fretzagias A1 S Haidas A1 T Thomaidis YR 1978 UL http://adc.bmj.com/content/53/6/511.abstract AB In an infant of 15 months with the diencephalic syndrome, urinary excretion of norepinephrine was moderately raised and epinephrine greatly so. It is suggested that catecholamine secretion may be due to sympathetic stimulation at the level of the diencephalon, by a space-occupying lesion pressing on the thalamohypothalamic pathway. Some of the symptoms of the diencephalic syndrome such as euphoria, irritability, skin pallor, and hypertension may be the result of catecholamine secretion.
