Determination of Total Urinary Catecholamines
SYNOPSIS Two patients with phaeochromocytoma having atypical biochemical features are described. Total catecholamine excretion was normal in one and only slightly raised in the other; both had a diagnostic rise in output of metadrenaline and 4-hydroxy-3-methoxymandelic acid whilst 4-hydroxy-3-methoxyphenylglycol excretion was increased in one of them. During hypertensive attacks adrenaline excr...
متن کامل[Arterial hypertension and increased urinary catecholamines].
We report the history of a 39-year-old-man who suffered from refractory arterial hypertension and who was referred to us for the diagnosis of phaeochromocytoma due to increased urinary free catecholamines. The work-up revealed the diagnosis of cocaine-induced arterial hypertension. The pathogenesis of cocaine-induced arterial hypertension as well as the differential diagnosis of increased urina...
متن کاملHyperadrenergic syndrome in severe tetanus: extreme rise in catecholamines responsive to labetalol.
The hyperadrenergic syndrome that occurs in tetanus is characterised by hypertension, tachycardia, and increased systemic arteriolar resistance. A 74 year old man with tetanus was found to have very high catecholamine concentrations--as high as those in phaeochromocytoma--and the fluctuations in blood pressure and heart rate were measured to see whether they paralleled changes in the catecholam...
متن کاملWork-related stress and urinary catecholamines among laboratory technicians.
OBJECTIVES Work-related psychosocial hazards are associated with adverse health outcomes among workers. The association between psychosocial hazards and physiological health outcomes among laboratory technicians has not been studied previously. The objective of this study was to measure the association between work-related psychosocial hazards and the level of urinary catecholamines of laborato...
متن کاملPlasma and urinary catecholamines in salt-sensitive idiopathic hypertension.
Nineteen patients with normal renin idiopathic hypertension were arbitrarily classified as salt-sensitive or salt-resistant depending on whether their mean arterial pressure did or did not increase by 8% or more when sodium intake was increased. The responses of the two subsets and of five normal subjects to sodium intakes of 9, 109, and 249 mEq/day given for 7 days were as follows: The salt-se...
