Prolonged survival in a young Dobermann with adrenal neuroblastoma

Veterinary Record Case Reports, Volume 14, Issue 1, February 2026.
Abstract A 1‐year‐old Dobermann presented with recurrent episodes of acute diarrhoea and weight loss starting at 5 months of age. An adrenal mass was identified via ultrasound and computed tomography, leading to adrenalectomy. A diagnosis of adrenal neuroblastoma was obtained through histopathology and immunohistochemistry.

Measurement of fractionated plasma metanephrines for exclusion of pheochromocytoma: Can specificity be improved by adjustment for age?

BMC Endocrine Disorders, 2005
Background Biochemical testing for pheochromocytoma by measurement of fractionated plasma metanephrines is limited by false positive rates of up to 18% in people without known genetic predisposition to the disease.

An unusual and interesting case of phaeochromocytoma

Journal of Clinical and Scientific Research, 2020
Phaeochromocytomas are catecholamine-secreting tumours that arise from chromaffin cells of the adrenal medulla. The common age of onset is between the third and fifth decades of life.

Pitolisant Inhibits Alcohol Drinking and Improves Withdrawal Negative Affect Through Lateral Habenula Histaminergic Signaling in Mice

CNS Neuroscience &Therapeutics, Volume 32, Issue 1, January 2026.
Pitolisant, an FDA‐approved H3R antagonist, counteracts the rewarding and sedative effects of ethanol, reduces alcohol intake, and alleviates the negative affect during withdrawal. This might occur via the antagonism of presynaptic autoreceptors and heteroreceptors H3Rs in the lateral habenula, thereby activating the H2R/p‐CREB/BDNF signaling and ...

Modified Pisano Method for Estimating Urinary Metanephrines

Clinical Chemistry, 1973
Abstract The Pisano method [Clin. Chim. Acta 5, 406 (1960)] for estimating urinary metanephrine, used in the screening of hypertensive persons for pheochromocytoma, has been modified by replacing ion-exchange chromatography with differential solvent extraction.

A Multicenter, Retrospective Analysis of Long‐Term Survival in 255 Dogs With Pheochromocytoma Treated With Alpha‐Adrenoreceptor Antagonists or Surgery (2010–2021)

Journal of Veterinary Internal Medicine
Background The survival of dogs with pheochromocytoma (PCC) treated with adrenoreceptor antagonists has not been described or compared to surgically managed cases. Hypothesis/Objectives The objective of this study is to evaluate the survival of medically

Correlation between malondialdehyde and metanephrine in patients with acute lymphoblastic leukemia

مجلة بغداد للعلوم, 2014
Acute lymphoblastic leukemia (ALL) is one of the most common diseases , so in this study the serum level of malondialdehyde and its relationship with metanephrine was investigated in acute lymphoblastic leukemia patients over one month of treatment. Some

Enzyme and acid deconjugation of plasma sulfated metanephrines [PDF]

Clinica Chimica Acta, 2014
Total (i.e. free+sulfated) metanephrines in plasma is a biomarker for the diagnosis of pheochromocytoma/paraganglioma. Sulfated metanephrines must be completely deconjugated by perchloric acid hydrolysis or sulfatase treatment prior to analytical measurement to enable quantification by current techniques.

11C‐Hydroxyephedrine PET/CT for preoperative surgical planning in large pheochromocytoma and paraganglioma

Journal of Neuroendocrinology, Volume 38, Issue 1, January 2026.
Abstract Early detection of metastases and timely surgical intervention play a crucial role in the management of neuroendocrine tumors. In large‐sized pheochromocytomas and sympathetic paragangliomas (PPGL), functional imaging with positron emission tomography (PET) is recommended, as it improves the detection of metastases, which may go undetected on ...
