BACKGROUND: Hungry bone syndrome is a well-established cause of postoperative hypocalcemia in thyrotoxicosis. To date, the incidence of hungry bone syndrome after total thyroidectomy is unclear. This prospective study examined the incidence of postthyroidectomy hungry bone syndrome and its correlation with preoperative bone mineral density. METHODS: Forty thyrotoxic subjects (Group A; age: mean ± SD; 36.5 ± 9.8 years) and 40 euthyroid controls with benign thyroid nodules (Group B) undergoing total thyroidectomy were evaluated for preoperative bone mineral density and serum calcium, magnesium, phosphorus, parathyroid hormone, alkaline phosphatase, and 25-Hydroxy Vitamin D serially...

Permanent hypoparathyroidism following thyroid surgery is rare. Its prevalence is reported to be below 1-2% if surgery is performed by experienced thyroid surgeons. Parathyroid identification and preservation in situ with good vascular supply is the mainstay of safe thyroid surgery. However, if the parathyroid glands are damaged, autotransplantation should be undertaken to preserve their function. Parathyroid transplantation can be considered in three distinct modes of application: (I) fresh parathyroid tissue autotransplantation during thyroidectomy in order to reduce the risk of permanent hypoparathyroidism; (II) cryopreserved parathyroid tissue autotransplantation in patients with permanent hypoparathyroidism; (III) parathyroid allotransplantation in patients with permanent hypoparathyroidism when cryopreserved parathyroid tissue is not available for grafting...

BACKGROUND: In dialysis and renal transplant patients with secondary and tertiary hyperparathyroidism (HPT), the value of intraoperative parathyroid hormone (ioPTH) during parathyroidectomy (PTX) and its association with long-term PTH levels are unknown. The present study aims at evaluating the relationship of ioPTH with long-term PTH levels post-PTX in dialysis and renal transplant patients in a single-center study. METHODS: The ioPTH was measured in 57 dialysis patients (33 females and 24 males) and 18 renal transplant recipients (12 males and 6 females) who underwent PTX from 2005 to 2015 for refractory HPT...

BACKGROUND: Hypocalcaemia (HC) is the most common complication after thyroid surgery in differentiated thyroid cancer and leads to a prolongation of the hospital stay. While risk factors for HC after total thyroidectomy (TE) are well investigated, only few studies have been published about HC risk factors after completion of thyroidectomy. Our aim was to identify potential risk factors for HC after completion of TE and to compare these incidences with figures from primary total TE. MATERIALS AND METHODS: A retrospective cohort study was undertaken including patients undergoing completion of TE between 2002 and 2013 in our tertiary care centre...

Stephen J Marx
Introduction Familial hypocalciuric hypercalcemia (FHH) causes lifelong hypercalcemia with features that overlap with typical primary hyperparathyroidism (PHPT). The incompleteness of this overlap has led to divergent nomenclatures for FHH. I compare two nomenclatures. One sets FHH as an entity distinct from PHPT. The other groups FHH with PHPT but conditions FHH as atypical PHPT. Methods I analyzed selected articles about calcium-sensing receptors, FHH, PHPT, CASR, GNA11, and AP2S1. Results FHH usually results from a heterozygous germline inactivating mutation of the CASR, and less frequently from mutation of GNA11 or AP2S1...

Autoimmune Polyglandular Syndrome type 1 (APS-1) is a subtype of the autoimmune polyendocrine syndrome characterized by the simultaneous or sequential dysfunction of multiple endocrine or non-endocrine glands. A clinical diagnosis of APS-1 is typically based on the presence of at least two of three following criteria: chronic mucocutaneous candidiasis, hypoparathyroidism and adrenal insufficiency. The first identified causative mutated gene for APS-1 is autoimmune regulator (AIRE) encoding a critical transcription factor, which is primarily expressed in the medullary thymic epithelial cells (mTECs) for generating central immune tolerance...

Context: Daily PTH(1-34) administrations can reduce the required total daily dose of calcium/calcitriol and restore normocalcemia in refractory hypoparathyroidism. However, most of the PTH(1-34) trials were conducted on small cohorts including subjects with hypoparathyroidism of various etiologies and quality of life(QOL) was not investigated. Objective: To investigate the effects of 24 month PTH(1-34) treatment in a homogeneous cohort of adult subjects with postoperative hypoparathyroidism and to evaluate quality of life(QOL) changes...

Post-surgical hypoparathyroidism and hypocalcemia are known to occur after nearly 50% of all thyroid surgeries as a result of accidental disruption of blood supply to healthy parathyroid glands, which are responsible for regulating calcium. However, there are currently no clinical methods for accurately identifying compromised glands and the surgeon relies on visual assessment alone to determine if any gland(s) should be excised and auto-transplanted. Here, we present Laser Speckle Contrast Imaging (LSCI) for real-time assessment of parathyroid viability...

The patients with hypoparathyroidism have been treated with active vitamin D(ie, alfacalcidol and calcitriol). Parathyroid hormone(PTH)increases extracellular calcium concentration partly through the activation of vitamin D, and active vitamin D corrects hypocalcemia mainly by increasing intestinal calcium abosorption. PTH coordinately increases blood calcium level with vitamin D in bone and kidney, however, renal tubular reabsorption of calcium is regulated by PTH-dependent mechanism. Hypercalciuria is an complication of long-term vitamin D treatment for PTH-deficient hypoparathyroidism...

BACKGROUND: Hypoparathyroidism, sensorineural hearing loss, and renal disease (HDR) syndrome, also known as Barakat syndrome, is a rare genetic disorder with high phenotypic heterogeneity caused by haploinsufficiency of the GATA3 gene on chromosome 10p14-p15. For these reasons, the diagnosis of HDR syndrome is challenging and requires a high index of suspicion as well as genetic analysis. CASE PRESENTATION: A 14-month-old boy, with sensorineural hearing loss in both ears, showed typical radiological features of X-linked stapes gusher on preoperative temporal bone computed tomography (CT) for cochlear implantations...

Wolfram syndrome (WFS) is a rare autosomal recessive disease with non-autoimmune childhood onset insulin dependent diabetes and optic atrophy. WFS type 2 (WFS2) differs from WFS type 1 (WFS1) with upper intestinal ulcers, bleeding tendency and the lack ofdiabetes insipidus. Li-fespan is short due to related comorbidities. Only a few familieshave been reported with this syndrome with the CISD2 mutation. Here we report two siblings with a clinical diagnosis of WFS2, previously misdiagnosed with type 1 diabetes mellitus and diabetic retinopathy-related blindness...
