#2176 New MENIN Mutation Associated with Familial Isolated Hyperparathyroidism. Clinical Case of Three Young Sisters.

Introduction: The primary hyperparathyroidism (PHPT) is a sporadic disorder in the majority of cases, and only 5-10% of cases are associated with familial syndromes. The following familial syndromes associated with PHPT are known to date: multiple endocrine neoplasia type 1 (MEN1), type 2A (MEN2A), type 4 (MEN4), hyperparathyroidism-jaw tumor syndrome (HPT-JT), familial hypocalciuric hypercalcemia (FHH), neonatal severe hyperparathyroidism (NSHPT) and familial isolated hyperparathyroidism (FIHP). FIHP is defined as hereditary PHPT without the association with other diseases or tumors and may be caused by mutations in MEN1, HRPT2, or CASR genes.

#1998 Vitamin D, Bone Mineral Density and Fracture Risk Assessment in Patients with Neuroendocrine Tumors

Introduction: Some papers have recently described an association between neuroendrocrine tumors (NET) and both vitamin D deficiency (VDD) and low bone mineral density (BMD). The ten-year risk of osteoporotic fractures can be calculated with the FRAX algorithm.

#1289 Reduced 25-OH-Vitamin D Levels in Patients with Chronic Autoimmune Atrophic Gastritis

Introduction: Chronic atrophic autoimmune gastritis (CAAG) is characterized by parietal cells disruption leading to hypochlorhydria and vitamin B12 malabsorption. An increased risk of osteoporosis was reported in patients with long-standing hypochlorhydria. Only few studies reported a possible association between CAAG and 25OHVitamin D (25OHvitD) deficiency.

#1267 Two Cases of Parathyroid Cancer with Pulmonary Metastasis

Introduction: Parathyroid cancer(PC) is a rare disease accounting for less then 1% of all patients with primary hyperparathyroidism. The prognosis of patients with parathyroid carcinoma is variable; more than 50% have a persistent or recurrent disease due to a regional or distant disease.
