[[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.

[Ultrasonography-guided therapeutic procedures in the neck region].

Background: Minimally invasive therapeutic procedures in medicine have become very popular because of the reduced risk compared to classic surgical treatment, speed of recovery, little or no side effects, and frequently lower cost. One of these methods is ultrasonography-guided percutaneous injection of 95% ethanol (PEIT, percutaneous ethanol injection therapy), which is especially suitable for the neck region. Other methods like laser photocoagulation (ILP) or radiofrequency ablation (RFA) are more aggressive and expensive.

Ultrasonographic evaluation of parathyroid hyperplasia in dialysis patients.

Secondary hyperparathyroidism (SHPT) is one of the most common complications in patients with chronic kidney disease (CKD). Bone and mineral disorders, increased morbidity and mortality are the consequences of SHPT. Therefore, prevention and control of hyperparathyroidism is one of the main objectives in the management of patients with CKD, particularly in dialysis patients.

Urokinase-type plasminogen activator and its inhibitor in thyroid neoplasms: a cytosol study.

Purpose: Higher levels of urokinase-type plasminogen activator (uPA) and its inhibitor (PAI-1) are linked to the poor prognosis in a variety of malignances. uPA and PAI-1 were expressed in most thyroid carcinomas, as had been measured immunohistochemically. However, no relationship between their expression and clinicopathological parameters were found.

[Ultrasonography methods in the diagnosis of renal osteodystrophy].

Bone disease, i.e. renal osteodystrophy, is commonly seen in patients with chronic renal failure.

Prevention and treatment of secondary hyperparathyroidism: still a challenge for the nephrologist?

Secondary hyperparathyroidism is a well known complication of chronic renal insufficency. It is not only a state of increased parathyroid hormone secre-tion but also a state of parathyroid gland hyperplasia. Prevention and treatment of secondary hyperpara-thyroidism is a huge challenge for the nephrologist, despite new agents for the treatment of hyperphos-phataemia, new vitamin D analogues and calci-mimetics.
