Evaluation of preoperative ultrasonographic and biochemical features of patients with aggressive parathyroid disease: is there a reliable predictive marker?
Arch. endocrinol. metab. (Online); 60 (6), 2016
ABSTRACT Objective Parathyroid cancer (PC) represents < 1% of cases of PHPT. Tumors demonstrating atypical histopathologic features and don’t fulfill criteria for carcinoma are classified as atypical adenomas (APA). The purpose of this study was to determine a biochemical or ultrasonographic f...

High frequency of asymptomatic hyperparathyroidism in patients with fibromyalgia: random association or misdiagnosis?
Rev. bras. reumatol; 56 (5), 2016
ABSTRACT Fibromyalgia (FM) and hyperparathyroidism may present similar symptoms (musculoskeletal pain, cognitive disorders, insomnia, depression and anxiety), causing diagnostic confusion. Objectives: To determine the frequency of asymptomatic hyperparathyroidism in a sample of patients with FM and to e...
Hypocalcemia development in patients operated for primary hyperparathyroidism: Can it be predicted preoperatively?
Arch. endocrinol. metab. (Online); 60 (5), 2016
ABSTRACT Objective Primary hyperparathyroidism (PHP) is a common endocrine disease, and its most effective treatment is surgery. Postoperative hypocalcemia is a morbidity of parathyroid surgeries, and it may extend hospitalization durations. The purpose of this study is to determine the predictive fact...

Experience with a third-generation parathyroid hormone assay (BIO-PTH) in the diagnosis of primary hyperparathyroidism in a Brazilian population
Arch. endocrinol. metab. (Online); 60 (5), 2016
ABSTRACT Objective To evaluate the usefulness of a third-generation PTH assay in the diagnosis of primary hyperparathyroidism (PHPT). Subjects and methods Forty-one PHPT patients (4 men and 37 women) with 61.2 ± 10.9 (mean ± SD) years, were studied and had PTH levels measured with two different met...

The deceptive concept of hypoparathyroidism and recurrence after parathyroidectomy in dialysis patients: are we offering a Procrustean bed to some patients?
Rev. Col. Bras. Cir; 43 (5), 2016
ABSTRACT Objective: to analyze the frequency of hypoparathyroidism and of its recurrence after parathyroidectomy in dialysis patients according to different existing classifications. Methods: we conducted a retrospective study of 107 consecutive dialysis patients undergoing total parathyroidectomy with...
Are PTH levels related to oxidative stress and inflammation in chronic kidney disease patients on hemodialysis?
J. bras. nefrol; 38 (3), 2016
Abstract Introduction: Patients at end stage renal disease have higher levels of inflammation and oxidative stress than the general population. Many factors contribute to these issues, and the parathyroid hormone (PTH) is also implicated. Objective: The study was conducted in order to assess the relati...

Rev. méd. Chile; 144 (9), 2016
Background: Patients undergoing hematopoietic cell transplantation (HCT) are at increased risk of developing osteoporosis. Aim: To determine the frequency and severity of Vitamin D deficiency, secondary hyperparathyroidism and low bone mass in patients undergoing HCT. Patients and Methods: Analysis of th...
Requests of laboratory tests for the diagnosis and management of calcium-phosphate disorders in Spain
Rev. méd. Chile; 144 (8), 2016
Background: Knowledge about the variability in the request of calcium-phosphate metabolism laboratory tests in primary care is important to design strategies to improve health system efficiency. Aim: To compare the inter-practice variability in calcium-phosphate metabolism laboratory tests requested by g...

Primary Hyperparathyroidism: The Influence of Bone Marrow Adipose Tissue on Bone Loss and of Osteocalcin on Insulin Resistance
Clinics; 71 (8), 2016
OBJECTIVES: Bone marrow adipose tissue has been associated with low bone mineral density. However, no data exist regarding marrow adipose tissue in primary hyperparathyroidism, a disorder associated with bone loss in conditions of high bone turnover. The objective of the present study was to investigate ...
