Different diagnostic cut-off values of urinary fractionated metanephrines according to sex for the diagnosis of pheochromocytoma in Korean subjects.
The diagnosis of pheochromocytoma depends on the documentation of catecholamine overproduction. The use of urinary fractionated metanephrines has recently become common for the diagnosis of pheochromocytoma. In order to avoid false positive and false negative results, optimal cut-off levels are necessary; however, there have been few published reports on whether different cut-off levels are n...
متن کاملPlasma chromogranin A or urine fractionated metanephrines follow-up testing improves the diagnostic accuracy of plasma fractionated metanephrines for pheochromocytoma.
CONTEXT The initial diagnosis of pheochromocytoma relies on plasma fractionated metanephrines levels. Normal levels exclude pheochromocytoma, but positive tests have a low positive predictive value due to the disease's rarity. OBJECTIVES The objective of the study was to evaluate three approaches to distinguish between true-positive and false-positive tests: 1) increased cutoff for plasma fra...
متن کاملEffect of Estrogen and Progesterone on Cytokines Levels at Different Time Intervals after Traumatic Brain Injury
Introduction: Following a traumatic brain injury (TBI), the excessive release of proinflammatory cytokines is major cause of cerebral edema that can cause permanent neuronal loss. This study examined the changes in brain concentrations of proinflammatory cytokines IL-1, IL-6, TNF-α and TGF- after different doses of estrogen or progesterone treatment in brain-injured rats at 6 and 24 h post...
متن کاملImprovement of insulin sensitivity after adrenalectomy in patients with pheochromocytoma.
OBJECTIVE Decreased insulin secretion is considered to be the main cause for pheochromocytoma-associated diabetes mellitus. Data from animal and evidence from clinical studies suggest that catecholamines can induce insulin resistance. However, there is no study investigating the effect of catecholamine excess on insulin resistance in patients with pheochromocytopma by the euglycemic hyperinsuli...
متن کاملThe local spread of pheochromocytoma after adrenalectomy with a rupture of the tumor capsule at the time of the surgery
INTRODUCTION We present a case of a 29-year-old patient treated due to fully symptomatic pheochromocytoma of the right adrenal gland. CASE PRESENTATION Patient was operated on and an open right-sided adrenalectomy was performed. At the time of the surgery, a rupture of the tumor capsule occurred.
