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 کاملEvaluation of the effect of heat exposure on the autonomic nervous system by heart rate variability and urinary catecholamines.
The aim of this study was to investigate the usefulness of heart rate variability (HRV) and urinary catecholamines (CA) as objective indices of heat stress effect. We examined physiological responses, subjective symptoms, HRV and urinary CA to evaluate the effect of heat exposure on the autonomic nervous system. Six healthy male students volunteered for this study. They were exposed on differen...
متن کاملBeyond catecholamines: Measuring autonomic responses to psychosocial context.
Despite longstanding interest among human biologists in autonomic responses to socioecological context or culture change, the adoption of autonomic measures has been limited by methodological challenges. Catecholamine secretion is the most direct measure, but not all study designs are amenable to urinary sampling, and blood pressure lacks specificity to the parasympathetic or sympathetic divisi...
