PARATHYROID CARCINOMA: ULTRASONOGRAPHIC AND CLINICAL EXPERIENCE.

Parathyroid cancer is an extremely rare malignancy that usually leads to hyperparathyroidism. The aim of this report is to present clinical and ultrasonographic features of tumors in six patients (5 females; mean age 53.2 years) treated for parathyroid carcinoma at the Department of Nuclear Medicine during 20 years.

[[GUIDELINES FOR THE PREVENTION, MONITORING AND THERAPY OF CHRONIC KIDNEY DISEASE-METABOLIC BONE DISEASE IN PATIENTS WITH CHRONIC KIDNEY DISEASE].].

Chronic kidney disease (CKD) is a systemic disease with numerous complications associated with increased morbidity and mortality. Chronic kidney disease-metabolic bone disease (CKD-MBD) starts at early stages of CKD with phosphorus accumulation and consequent initiation of numerous events that result with the development of secondary hyperparathyroidism with changes on bones and extraskeletal tissues. The most important and clinically most relevant consequences of CKD-MBD are vascular calcifications which contribute to cardiovascular mortality.

Parathyroid carcinoma in pregnancy.

A 24-year-old female patient with parathyroid carcinoma, the rarest endocrine malignancy, had two pregnancies. In the first pregnancy, she had severe nausea and fatigue. Hypercalcemia and hyperparathyroidism were diagnosed in the postpartum period.

Urokinase plasminogen activator and its inhibitor type-1 as prognostic factors in differentiated thyroid carcinoma patients.

Objective: To investigate the prognostic value of urokinase-type plasminogen activator (uPA) and its inhibitor, type-1 plasminogen activator inhibitor (PAI-1), in differentiated thyroid cancer.

Study Design: Prospective cohort study.

Setting: University hospital.

Diagnostic pitfalls in parathyroid gland cytology.

The aim of this study is to establish possibilities of using cytology in the diagnosis of parathyroid gland adenoma. 475 patients, all suspected to have parathyroid gland disease, were examined over a three-year period (from 1 of January 2006 to 31 of December 2008) in the Clinical Department of Nuclear Medicine and Radiation Protection, University Hospital Center Zagreb, Croatia. Ultrasound guided fine needle aspiration biopsy (UG-FNAB) of suspected occurrences determined by ultrasound was done.
