Effect of Parathyroidectomy on Cardiovascular Health

Background The cardiovascular manifestation of primary hyperparathyroidism (PHPT) has been debated in many years. PHPT was once a highly symptomatic disease with severe symptoms. Today, the clinical presentation of the disease is often asymptomatic or with few symptoms at diagnose. This may be the reason why the literature regarding this ...

Phase N/A

Percent Change in Baseline Bone Mineral Density (BMD) After Parathyroidectomy in Patients With Primary Hyperparathyroidism

The research plan is for a retrospective review to be performed of a prospectively maintained parathyroid database within the Department of Surgical Oncology at the University of Texas MD Anderson Cancer Center. The patient cohort for this study consists of all patients with primary hyperparathyroidism who underwent parathyroidectomy and also ...

Phase N/A

Randall's Plaque Study: Pathogenesis and Relationship to Nephrolithiasis

In order to attempt to explain the pathogenesis of renal calculi, the investigators videotape and document the location and characteristics of each stone, papillae and calyces. One or more small papillary biopsies are taken for analysis to help determine the point of origin of the kidney stone and histological studies ...

Phase N/A

The Application of Rapid PTH Test Paper in Operation of Hyperparathyroidism

Primary hyperparathyroidism is a clinically common disease. At present, the gold standard for determining whether the operation is successful is based on the Miami principle. That means The PTH hormone decreased to 30% of the baseline level after 15min after the tumor was removed. However, due to the differences in ...

Phase N/A

Variables That Are Correlated to Developing Multiple Endocrine Neoplasia (MEN) and Pancreatic Neuroendocrine Tumors (PNET)

Researchers aim to identify somatic mutations and inherited genetic variants which may help predict the development of PNET in patients with hyperparathyroidism.

Phase N/A

The Efficacy and Safety of Microwave Ablation for Mild-to-moderate Secondary Hyperparathyroidism Patients Undergoing Hemodialysis

Secondary hyperparathyroidism(SHPT) is common in hemodialysis(HD) patients. SHPT can damage cardiovascular system , bone system, and so forth. The treatment of SHPT of HD patients includes dietary phosphate restriction, the use of medicines, parathyroidectomy, and microwave ablation, which is a new method booming over the past decade. However, In the ...

Phase N/A

the Study on Prognostic for Hemodialysis Patients

It is common that the abnormalities in parathyroid hormone (PTH) levels appear in patients with moderate and advanced chronic kidney diseases (CKD). CKD-mineral and bone disorder (CKD-MBD), manifested by the serum calcium (Ca), phosphorus (P), and parathyroid hormone (PTH) levels, and other abnormalities such as vitamin D metabolism and bone ...

Phase N/A

Gene Expression in Hyperparathyroidism

Patient charts will be reviewed to collect demographic data, pre-operative and post-operative clinical and laboratory data, operative reports, and pathology reports. Archived formalin-fixed paraffin-embedded (FFPE) tissue blocks from surgical specimens of patients will be stained for parafibromin to evaluate for HRPT2 mutations.

Phase N/A

Preliminary Study Concerning the Validity of Parathyroid Exploration on a CZT Camera

The goal is to determine if parathyroid tomoscintigraphy on a CZT camera can provide at least equivalent diagnostic performance, compared with planar pinhole imaging.

Phase N/A

Insulin Resistance in Primary Hyperparathyroidism

To be conducted at the Karolinska University Hospital, Stockholm. Patients with fb-glucos >6.1 and HbA1c without medical treatment will be included after informed consent and randomised to parathyroidectomy (PTX) within three months or not. The groups will be examined 4 4 weeks before and 122 weeks after PTX, similar for ...
