Objective: Hypertensive urgency is defined as a severe elevation of blood pressure (BP) without target organ damage. In emergency room, hypertensive urgency has been conventionally managed by antihypertensive medication. However, there has been increasing concern for the safety of antihypertensive medication in hypertensive urgency. Thus, this study was to compare the clinical efficacy of resting and antihypertensive medication in managing hypertensive urgency.
Methods: For 138 hypertensive urgency patients admitting in emergency room of Veterans Health Service (VHS) medical center, a single-center, randomized controlled trial was conducted. Hypertensive urgency patients were randomly allocated into one group out of resting group and antihypertensive medication (telmisartan) group at admission. We serially checked their BP every 30 min for 2 h, and evaluated change levels and decline of BP. Primary end point of the study was mean BP reduction from 10 to 35%. Additionally, change and decline of SBP and DBP were serially compared over 2 h.
Result: The rate of individuals approaching primary end point was 68.5% in rest group and 69.1% in medication group (P = 0.775). The change levels of BP for 2 h had no significant difference in SBP (P = 0.882) and DBP (P = 0.411) between resting group and medication group. The decline of BP after 2 h also did not show any statistical difference in both SBP (P = 0.065) and DBP (P = 0.032) between both groups.
Conclusion: There was no significant difference between resting and antihypertensive medication in reducing BP of hypertensive urgency patients. This finding suggests the clinical efficacy of resting in managing hypertensive urgency.

Cushing syndrome due to ectopic adrenocorticotropic hormone (ACTH) secretion (EAS) is rare and may progress rapidly, making treatment very challenging. We report a 27-year-old woman with metastatic neuroendocrine tumor (NET) who presented with sudden onset and rapidly progressing fatigue, muscle weakness, and weight gain. Laboratory findings confirmed severe EAS with new onset hypocalcemia, hypokalemia, and hyperglycemia.

Paragangliomas, a type of extra-adrenal tumour, albeit rare, are dangerous due to their high metastatic potential and risk of hypertensive crisis from massive catecholamine release. It typically presents with sympathetic overdrive symptoms such as diaphoresis, headache, and palpitation, accompanied by substantially high plasma metanephrines level and mass on contrasted computed tomography abdomen and pelvis, whilst some are found incidentally. In this report, we discuss a case of an extra-adrenal lesion located near susceptible major structures with extensive vascularisation, in a patient with near-death experience.

Purpose: The delayed or missed diagnosis of secondary hypertension contributes to the poor blood pressure control worldwide. This study aimed to assess the diagnostic approach to primary aldosteronism (PA) and pheochromocytoma (PHEO) among Italian centers associated to European and Italian Societies of Hypertension.
Methods: Between July and December 2023, a 10-items questionnaire was administered to experts from 82 centers of 14 Italian regions and to cardiologists from the ARCA (Associazioni Regionali Cardiologi Ambulatoriali) Piemonte.

Pheochromocytoma is a rare tumor originating from the adrenal gland, characterized by the secretion of catecholamines. Due to the risk of hypertensive crises associated with catecholamine release, surgical procedures in pheochromocytoma patients are risky. In this case report, laparoscopic appendectomy for acute appendicitis in a patient who has pheochromocytoma will be presented.
