The effect of teriparatide on serum Dickkopf-1 levels in postmenopausal women with established osteoporosis.

Objective: Parathyroid hormone increases the differentiation of osteoblast precursors through canonical wingless (Wnt) signalling, resulting in an osteoanabolic effect. We aimed to evaluate serum levels of the Wnt-inhibitor Dickkopf-1 (Dkk-1) in postmenopausal women with established osteoporosis and their changes with teriparatide (TPTD - human recombinant PTH 1-34).

Design And Patients: A total of 31 postmenopausal Caucasian women with established osteoporosis (mean age 66.

Sequential treatment of severe postmenopausal osteoporosis after teriparatide: final results of the randomized, controlled European Study of Forsteo (EUROFORS).

It is unclear which treatment should be given after stopping teriparatide therapy for severe osteoporosis. In a prospective, randomized, controlled, 2-yr study, we compared BMD effects and clinical safety of three follow-up treatments (anabolic with teriparatide, antiresorptive with raloxifene, or no active treatment) after 1 yr of teriparatide. Postmenopausal women with osteoporosis and a recent fragility fracture received open-label teriparatide (20 microg/d) for 12 mo before they were randomized (3:1:1) to continue teriparatide (n = 305), switch to raloxifene 60 mg/d (n = 100), or receive no active treatment for the second year (n = 102).

Scintigraphic, biochemical, and clinical response to zoledronic acid treatment in patients with Paget's disease of bone.

Bisphosphonates have long been used with success in the treatment of Paget's disease of bone (PDB). The aim of this study was to evaluate the early (up to 3 months) and late (at 12 months) scintigraphic, biochemical, and clinical response to a single intravenous infusion of zoledronic acid (ZOL) in patients with PDB serially assessed for 1 year. Nine patients with 30 bone lesions caused by PDB were prospectively evaluated.

No difference between strontium ranelate (SR) and calcium/vitamin D on bone turnover markers in women with established osteoporosis previously treated with teriparatide: a randomized controlled trial.

Unlabelled: Objective To evaluate the effect of strontium ranelate (SR) on bone turnover markers in women with established osteoporosis previously treated with teriparatide (TPTD--recombinant human PTH 1-34). DESIGN PATIENTS: Twenty-two postmenopausal Caucasian women (aged 65.7 +/- 1.

Endogenous intact PTH is suppressed during Teriparatide (rhPTH 1-34) administration in postmenopausal women with established osteoporosis.

Introduction: Teriparatide (recombinant human PTH 1-34/TPTD) is an osteoanabolic agent available for osteoporosis treatment. The aim of this prospective trial was to evaluate the acute and chronic effects of TPTD in endogenous intact PTH (iPTH) levels in postmenopausal women with established osteoporosis.

Materials And Methods: Thirty-six postmenopausal Caucasian women (age 66.

Sustained clinical inactivity and stabilization of GH/IGF-1 levels in an acromegalic patient after discontinuation of somatostatin analogue treatment.

Background: A 38-year-old woman first presented complaining of foot enlargement, finger numbness, arthralgia, fatigue, galactorrhoea and oligomenorrhea. Her symptoms in conjunction with her coarsened facial features and prognathism led to the suspicion of acromegaly.

Basic Procedures: Oral glucose tolerance tests (OGTT) were performed at initial presentation and almost yearly thereafter for a period of 14 years.

Serum thyrotropin concentration as a biochemical predictor of thyroid malignancy in patients presenting with thyroid nodules.

Purpose: Serum thyrotropin (TSH) is a well-established growth factor for thyroid nodules and suppression of TSH concentrations by administering exogenous thyroxine may interfere with the growth of established nodules as well as the formation of new thyroid nodules. The aim of this study was to investigate whether serum TSH at presentation is a predictor of thyroid malignancy in patients with thyroid nodules.

Methods: A total of 565 patients without overt thyroid dysfunction, who presented with palpable thyroid nodule(s) between 1988 and 2004 and underwent at least one fine-needle aspiration biopsy, were retrospectively evaluated.

Acute changes in serum osteoprotegerin and receptor activator for nuclear factor-kappaB ligand levels in women with established osteoporosis treated with teriparatide.

Objective: The mechanisms regulating the anabolic response of the skeleton to intermittent exogenous parathyroid hormone (PTH) administration are not fully elucidated. The aim of this prospective study was to evaluate the acute effect (up to 1 month) of teriparatide (TPTD; human recombinant PTH 1-34) on serum levels of osteoprotegerin (OPG) and receptor activator for nuclear factor-kappaB ligand (RANKL) in women with established osteoporosis.

Design: Twenty-three postmenopausal Caucasian women with established osteoporosis (mean age 66.

Cushing's syndrome in pregnancy: report of a case and review of the literature.

Cushing's syndrome (CS) during pregnancy is a rare nosology with only a few cases reported in the literature. Misdiagnosis is common, as the syndrome may be easily confused with preeclampsia or gestational diabetes. CS during pregnancy is usually associated with severe maternal and fetal complications.

Oral bisphosphonate adverse effects in 849 patients with metabolic bone diseases.

Objective: Bisphosphonates are potent antiresorptive agents used for a spectrum of metabolic bone diseases. The aim of this study was to compare the adverse effects (AEs) of alendronate, etidronate and risedronate prescribed in a non-selected population, attending a single institution on an outpatient basis.

Design: 849 patients receiving either alendronate (n=710), etidronate (n=181) or risedronate (n=130) were studied for a period of 1916 person-years.

Thyroid nodules - stepwise diagnosis and management.

Thyroid nodules are common in clinical practice. They may be solitary within a "normal" thyroid gland or dominant within a multinodular goiter. The incidence of thyroid nodules has been on the rise in recent decades, mainly due to the wider use of neck imaging.
