Abstract
Brown tumors are equally found in secondary and primary hyperparathyroidism. Craniofacial brown tumors involve the orbit, usually because of the osteodystrophy process that involves the maxilla and paranasal sinuses. The lesions do not necessarily need to be excised and may regress spontaneously aft...

Abstract
B-, H- and L-catepsine-like activity regarding Na-benzoyl-D,L-arginine-4-nitroanilide, L-leucine-4-nitroanilide and azocasein was studied in the blood plasma of patients with different diseases of thyroid, parathyroid and adrenal glands. It has been shown that the high H- catepsine-like activity con...

Abstract
The knowledge of parathyroid and thyroid anatomy helps a surgeon to localize important details and lessen complications, especially laryngeal palsy and hypoparathyroidism. The ligament of Berry and tuberculum Zuckerkandl cover the recurrent laryngeal nerve in the upper part of the thyroid lobes. The...

Abstract
We find also in nonsyndromic scenarios. In our study, were considered the latter. Between 2003 and 2008 in our Division of General Surgery 61 patients underwent operation for hyperparathyroidism, 13 for primary, 41 secondary and 7 tertiary. Twenty-six of these patients underwent also total thyroidec...

Abstract
CONTEXT: Parathyroid cysts are rare clinical and pathological entities, with less than 300 cases reported. The inferior parathyroid glands are most commonly involved, with left-side predominance. Parathyroid cysts may be functional or nonfunctional, depending on their association with hypercalcemia....

Abstract
Among 6621 patients submitted to neck US investigation, a PC (mean diameter 36.4+/-14.2 mm; range 25-61 mm) was diagnosed in 5 cases. Serum PTH levels were high in all the patients (221+/-140.7 pg/ml; range 111-456 pg/ml), whereas serum calcium levels only in 3 subjects (10.8+/-1.4 mg/dl; range 9.2-...

Abstract
Thyroid and parathyroid diseases are fairly common and can be either hereditary or sporadic in nature. Tumors and tumor-like processes account for the majority of surgical pathology specimens in both of these endocrine organs. Molecular alterations are well known to occur in both the hereditary and...

We reported the clinical manifestation and pathological findings in patients with hypercalcemia and metastatic calcification. In addition, we addressed the possible mechanism and the preventive strategy for the acute episode of ALI due to hypercalcemic crisis. We encountered five patients with long-...

To our knowledge this is a first population-based study on nonthyroid endocrine diseases. The results call for further studies to sort out the challengingly high sibling risk for many individual nonthyroid endocrine diseases, whether they are due to bias or possible recessive effects....

Abstract
The history of thyroid and parathyroid surgery dates back thousands of years, but the developments leading to the contemporary era began just over a century ago. Pioneers in the field include Billroth, Kocher, Mayo, and Halsted. This article examines the historical progress of operating on the thyro...

Abstract
We included 607 patients, representing 20% of the pediatric endocrine operations done between 1999 and 2005 in the United States. Seventy-six percent of patients were female. Among the procedures performed, 92% were thyroidectomies and 8% were parathyroidectomies. Surgeons were classified as follows...

Hospital data were available for 335 reoperations (85%). There were 134 avoidable (34%) and 201 unavoidable (66%) procedures. Primary hyperparathyroidism (HPT) and thyroid cancer each accounted for a third of cases. Of PR from LVC, 77% were avoidable compared with 22% from HVC (P < .001). Of TR from...

Abstract
USG. In the thyroid diseases group, USG was particularly useful: 1) to detect additional nodules in glands with suppressed thyroid tissue; 2) to disclose small thyroid nodules (<1 cm) in which it was possible to perform a USG-FNAC. In the parathyroid diseases group, USG was particularly useful for t...

The most common indication for parathyroid imaging is hyperparathyroidism, which is caused by a solitary parathyroid adenoma in most patients. The primary function of parathyroid imaging is localization of the abnormal parathyroid gland, enabling the surgeon to pursue a minimally invasive resection....

Abstract
Disease of the parathyroid glands presents most often with hypercalcaemia secondary to excess parathormone (PTH) production. This is due to a solitary functioning parathyroid adenoma. The role of imaging is primarily to localise the functioning adenoma. Disease of the thyroid may present with a neck...

Abstract
Viability of cryopreserved parathyroid cells is associated with duration of storage. Parathyroids preserved for greater than 24 months are unlikely to be viable. It seems reasonable to limit parathyroid cryopreservation to 24 months when frozen at -80 degrees C. Further studies are needed to optimiz...

Abstract
We define a syndrome featuring both hypophosphatemic rickets and hyperparathyroidism due to parathyroid hyperplasia as well as other skeletal abnormalities. We show that this disease is due to a de novo translocation with a breakpoint adjacent to alpha-Klotho, which encodes a beta-glucuronidase, and...

Abstract
Felix Mandl from Vienna has long been acclaimed as having carried out the first parathyroidectomy for primary hyperparathyroidism in 1925. He was not, however, the first surgeon to have seen the parathyroid glands, either at surgery or in the pathology laboratory. There is evidence that the first in...

Sestamibi scans correctly localized the parathyroid adenoma(s) in 133 (58.1%) of the 229 patients. The agreement between the 2 imaging procedures was moderate (kappa = 0.23; 95% conf...

Abstract
Parathyroid cysts are much less common than other cystic lesions of the neck. The great majority of parathyroid cysts are endocrine non-functioning. Parathyroid cysts may become symptomatic because of hormonal activity or due to the size and pressure effects. This is a case history of a 43 year-old...

FNA failed to recognize the parathyroid origin of the lesions in all but 2 cases with known hyperparathyroidism. Most aspirates were misinterpreted either as suspicious for or as thyroid neoplasms because of high cellularity and absence of colloid. Histologically, the lesions proved to be parathyroi...

Parathyroid (PT) hyperplasia is a major feature of secondary hyperparathyroidism (SH) in uremia. The transforming growth factor-alpha (TGFalpha) / epidermal growth factor receptor (EGFR)Ethgrowth loop is the main contributor to uremia-induced PT hyperplasia. Since integrin beta1 and focal adhesion k...
