Recurrent hyperparathyroidism: parathyroid carcinoma or parathyromatosis?

Alina Isaic , Flore Varcus , Maria Cornianu , Ioana Golu , Mihaela Vlad

Recurrent hyperparathyroidism (HPT) refers to reappearance of hypercalcemia after a normocalcemic period of at least 6 months post-parathyroidectomy. Parathyroid carcinoma is a rare cause of primary hyperparathyroidism (pHPT), accounting for 0.45.2% of cases. Parathyromatosis is defined as small nodules of hyperfunctioning parathyroid tissue scattered in the soft tissues of the neck and/or mediastinum. We describe two cases with recurrent hypercalcemia after surgical int...

Prenatal hypophosphatasia with severe skull bone deficits report of a case

Sideri Vassiliki , Karachaliou Feneli , Kapsabeli Helen , Doulgeraki Artemis , Dakalaki Anna , Papaevangelou Vassiliki

Hypophosphatasia (HPP) is a rare inherited disorder caused by loss-of-function mutations in the tissue-nonspecific alkaline phosphatase (TNSALP) gene. HPP B is a multisystemic B disorder with a predominantly B skeletal phenotype, with a clinical spectrum ranging from high lethality in early onset (<6 months) HPP to mild late-onset presentations. HPP skeletal disease in utero was thought to predict a lethal outcome. However a benign prenatal form (PB HPP) with a mild postna...

Clinical outcome in primary hyperparathyroidism: A 10-year tertiary care centre experience in Pakistan

Tabassum Shehla , Naeem Ehsun , Iqbal Javed , Islam Najmul

Background: Primary hyperparathyroidism (PHPT) is characterized by abnormal regulation of PTH secretion by calcium. The most common clinical presentation of PHPT is asymptomatic (80% cases), followed less likely by the classical symptoms of bones, stones, abdominal moans, and psychic groans. The diagnosis of PHPT is usually first suspected because of the finding of an elevated serum calcium concentration along with a rise in Parathyroid hormone (PTH) level. Serum phosphorus le...

Primary hyperparathyroidism-localisation studies’ sensitivity

Oros Sabina Elena , Gongu Robert Andrei , Diaconescu Laura Alina , Ivan Mirela , Grigorie Daniel , Gudovan Emilia , Dumitrascu Anda , Hortopan Dan , Goldstein Andrei

Primary hyperparathyroidism can be caused by adenoma, adenocarcinoma, parathyroid hyperplasia or ectopic parathyroid glands. The American Association of Endocrine Surgeons Guidelines for Definitive Management of Primary Hyperparathyroidism recommends imaging as a helping tool in locating the causative lesion rather than a must for diagnosis. Experienced surgeons rely on the intraoperative localisation of the lesion. Pre surgery localisation helps for a minimally invasive appro...

Characterization of the parathyroid hormone requests and hyperparathyroidism etiologies in a tertiary hospital

Gomes Vania , Matias Sampaio , Ferreira Florbela , Proenca Helena

Introduction: Hyperparathyroidism is a disease characterized by excessive secretion of parathyroid hormone (PTH). There are three main etiologies: primary (PHPT), secondary (SHPT) and tertiary hyperparathyroidism (THPT). PHPT is characterized by abnormal regulation of PTH secretion by calcium, resulting in hypersecretion of PTH relative to the serum calcium concentration. SHPT is the overproduction of PTH in context of hypocalcemia, most frequently because of vitamin D deficie...

Effect of bariatric surgery on free vitamin D3 levels

Marques-Pamies Montserrat , Pellitero Silvia , Granada Marisa , Santillan Cecilia Soledad , Lopez Maria , Puig-Domingo Manel

Total vitamin D levels are decreased in obese patients probably due to an increased volume of distribution mechanism. Recently introduced direct assays allow the measurement of free-vitaminD3 levels (fvitD3). Few data are available regarding fvitD3 levels in obese people and the effect of bariatric surgery upon its circulating concentration. We aimed to evaluate fvitD3 in a cohort of obese patients before and after bariatric surgery treatment and its relationship to phosphocal...

Primary hyperparathyroidism after thyroid surgery and autotransplantion of parathyroid gland

Marques Bernardo , Martins Raquel , Couto Joana , Santos Jacinta , Martins Teresa , Rodrigues Fernando

Introduction: Multiple endocrine neoplasia type 2A syndrome (MEN 2A) is caused by a germline mutation in the RET proto-oncogene and its phenotype includes medullary thyroid cancer, pheochromocytoma and primary hyperparathyroidism (PHPT). Parathyroid reimplantation in the sternocleidomastoid muscle or in the brachioradial muscle can be performed in case of intraoperative lesion of the parathyroid glands. In some cases, PHPT may occur due to the proliferation of autotransplanted...
