#1206 Two Cases of Ectopic ACTH-Secreting Neoplasm of Occult Origin Becoming Overt After Bilateral Adrenalectomy
Introduction: Cushing's syndrome (CS) is an endocrine disorder associated with serious consequences if not adequately treated. Nearly 80% of the cases of endogenous hypercortisolism are adrenocorticotropic hormone (ACTH) dependent, the ACTH source being pituitary in about 70-80% and ectopic in 10-15%. The ACTH source may remain occult in few cases for many years in spite of extensive investigations.

#2218 More than Rare Pheochromocytomas: Bilateral and Hemorrhagic, Giant and Metastatic
Introduction: Pheochromocytomas (PCC) are rare neuroendocrine tumors. These catecholamine-secreting tumors, with an average size of 4.9cm, are multiple in 10% of cases. About 10% are malignant but distant metastases are rare. Non-traumatic adrenal hemorrhage is an unusual potentially fatal event seen in PCC.

#799 Action of the Hypothalamic Proline-Rich Peptide During Vestibular Compensation Following Unilateral Labyrinthectomy
Introduction: There are uncovered mechanisms of the vestibular compensation (VC), following unilateral labyrinthectomy (UL). We consider the hypothalamic proline-rich peptide (PRP-1) action on Deiters’ lateral vestibular nucleus (LVN) neurons upon dynamics of recovery after UL was carried out.

#2159 Hepatic Steatosis Secondary to Peptide Receptor Radionuclide Therapy with Somatostatin Analogue
Introduction: Peptide Receptor Radionuclide Therapy (PRRT) with 177-Lutetium-DOTA-TATE is a therapeutic modality for neuroendocrine tumors. It has some well known side effects, concerning specially the bone marrow (from cytopenias to myelodysplastic syndrome), in addition to mild renal effects. Hepatotoxicity from PRRT is still being studied.

#1414 Non-functioning Adrenal Composite Pheochromocytoma-Ganglioneuroma Simultaneous with Subclinical Cushing's Syndrome Due to Contralateral Adrenal Hyperplasia - An Unusual Presentation
Introduction: “Composite” pheochromocytoma is a rare tumor, consisting of pheochromocytoma and neuroblastic tumors. The definite diagnosis is histological. Subclinical Cushing's syndrome refers to autonomous glucocorticoid production without specific signs and symptoms of Cushing's syndrome.

#790 Cerebellar and hypothalamic regulation of vestibular compensation after unilateral labyrinthectomy in rat
Introduction: The mechanisms of inhibitory regulation of neuronal activity of the vestibular system in health and in the vestibular compensation (VC) occurred with participation of the cerebellum, while non-cerebellar pathways are essential in restoring the stability of visual orientation during movement.

#760 Intraoperative Gamma Probe Detection of Metastatic Medullary Thyroid Carcinoma (MTC) with 111In-Pentetreotide
Introduction: MTC is a rare thyroid malignancy representing approximately 5-10% of all thyroid tumors. Early diagnosis and radical surgery are essential to reduce the morbidity and mortality associated with MTC. Somatostatin receptors (SSTRs) expression has been described in MTC with a variable pattern, SSTR2 being prevalent. Although somatostatin analogues demonstrated poor efficacy in the control of MTC growth, SSTR expression can be useful in Nuclear Medicine diagnostic procedures. 111In-pentetreotide scintigraphy and 68Ga-somatostatin analogues PET-CT represent valuable techniques in the detection of MTC, although with a lower sensitivity compared to 18F-DOPA PET-CT.

#944 Pheochromocytoma and Paraganglioma in Pediatric Age
Introduction: Pheochromocytoma (PHE) and paraganglioma (PGL) are rare tumors of the adrenal medulla and extra-adrenal sympathetic chromaffin tissue. Nearly 30% of them are familiar or associated with genetic syndromes (VHL, MEN2, NF1, SDH mutation, Pacak-Zhuang). Only 20% PHE occur before 20 years of age. Incidence of pediatric PHE is 0.3:1 million.

#53 The rise and fall of chromogranin A as an indicator for NET
Introduction: There is now general awareness that treatment with proton pump inhibitors (ppi) may cause moderate rises in circulating concentrations of gastrin and/or chromogranin A (CgA), thus decreasing the specificity of these markers in the diagnosis of neuroendocrine tumors (NETs). Due to their high efficacy, proton pump inhibitors (ppi) are one of the most frequently prescribed classes of drugs worldwide. Several studies in various countries report that 30% or more of in-patients have been prescribed ppi. Patients who are suspected of having a neuroendocrine tumor (NET) often have gastrointestinal (GI) symptoms for which ppi are prescribed and therefore they may be already taking ppi when their first blood sample is assayed for NET markers. We previously encountered a case of extreme rise in CgA which flagged the possibility of a NET, but was later shown to be due to ppi therapy alone. We present CgA and gastrin data in relation to ppi therapy and withdrawal for this patient. In order to see if this was an isolated incident, we audited all laboratory requests for CgA/gastrin in a two-year period and monitored those that provided details of ppi treatment/withdrawal.

#73 First experience of laparoscopic treatment of organic hyperinsulinism
Introduction: Pancreatic laparoscopic surgery is the most promising type of surgery. In the case of varied benign pancreatic tumors, laparoscopic surgery can become a standard surgical procedure. Among these uncommon tumors, pancreatic insulinomas are mostly benign and solitary. Successful management of patients with insulinomas depends on accurate localization of the tumor and the use of appropriate surgical techniques.
