Follicular thyroid carcinomas (FTCs) are the second most common malignant neoplasia of the thyroid and in general its prognosis is quite favorable. However, the occurrence of metastases or non-responsiveness to radioiodine therapy worsens the prognosis considerably. We evaluated immunohistochemically the expression of hypoxia-associated proteins by hypoxia-induced factor 1α (HIF-1α), the stroma-remodeling marker Tenascin C, as well as markers for the epithelial-mesenchymal transition (EMT), namely E-cadherin and slug in a series of 59 sporadic FTCs...

OBJECTIVE: Normal or elevated 24-hour urinary calcium (Ca) excretion is a diagnostic marker in primary hyperparathyroidism (PHPT). It is used to distinguish familial hypocalciuric hypercalcaemia (FHH) from PHPT by calculating the Ca/creatinine clearance ratio (CCCR). The variance of CCCR in patients with PHPT is considerable. The aim of this study was to analyse the parameters affecting CCCR in patients with PHPT. DESIGN: The data were collected prospectively. Patients with sporadic PHPT undergoing successful surgery were included in a retrospective analysis...

PURPOSE: The purpose of this study was to demonstrate the high number of kidney stones in primary hyperparathyroidism (PHPT) and the low number of in fact "asymptomatic" patients. METHODS: Forty patients with PHPT (28 female, 12 male; median age 58 (range 33-80) years; interquartile range 17 years [51-68]) without known symptoms of kidney stones prospectively underwent multidetector computed tomography (MDCT) and ultrasound (US) examinations of the urinary tract prior to parathyroid surgery...

Medullary carcinoma (MTC) is an aggressive tumour that derives from the thyroid parafollicular calcitonin-secreting cells (C cells). Lymph node metastasis may occur early in disease pathogenesis and is one of the most important negative prognostic parameters. Surgery is the only curative therapy while chemotherapeutic options are limited. Neuroendocrine differentiated C cells may express somatostatin receptors (SSTR), which have a wide range of biological actions including inhibitory effects on cell survival and angiogenesis and antiproliferative effects on cancer cell lines...

BACKGROUND: In terms of morbidity, prophylactic central neck dissection (CND; level 6) in potentially malignant thyroid disease is discussed controversially. The rates of (transient and permanent) hypoparathyroidism and palsy of the recurrent laryngeal nerve (RLN) after "first-step" (FS-)CND are analyzed in this study. METHODS: Bilateral and unilateral FSCND, i.e., lymph node dissection along the RLN before (total) thyroidectomy, was performed bilaterally in 68 (group 1) and unilaterally in 44 patients (group 2), respectively...

OBJECTIVE: The effects of thiazide medication in patients with primary hyperparathyroidism (PHPT) have so far not been elucidated. The aim of this study was to analyse the extent to which the administration of thiazides may influence biochemical parameters and therefore the diagnosis of PHPT in a large cohort of patients. DESIGN AND PATIENTS: The biochemical parameters of 1066 patients with PHPT were analysed, and drug history was documented. Calcium (Ca)/creatinine clearance ratio (CCCR) was calculated...

Net carbon sinks capable of avoiding dangerous perturbation of the climate system and preventing ocean acidification have been identified, but they are likely to be limited by resource constraints (Nature 463:747-756, 2010). Land scarcity already creates tension between food security and bioenergy production, and this competition is likely to intensify as populations and the effects of climate change expand. Despite research into microalgae as a next-generation energy source, the land-sparing consequences of alternative sources of livestock feed have been overlooked...

BACKGROUND: Fludarabine-based chemoimmunotherapy with rituximab is frequently used in patients with indolent and mantle-cell lymphomas who relapse after alkylating chemotherapy. We aimed to compare the efficacy and safety of rituximab with bendamustine or fludarabine in patients with relapsed, indolent, non-Hodgkin lymphoma and mantle-cell lymphoma. METHODS: For this randomised, non-inferiority, open-label, phase 3 trial, we recruited patients from 55 centres in Germany, who were subsequently randomised centrally according to prespecified randomisation lists with permuted blocks of randomly variable block size to rituximab (375 mg/m(2), day 1) plus either bendamustine (90 mg/m(2), days 1 and 2) or fludarabine (25 mg/m(2), days 1-3) every 28 days for a maximum of six 28-day cycles...

BACKGROUND: Adherence to medication and lifestyle interventions are essential keys for the management of hypertension. In this respect, a structured educational program for hypertensive patients has got remarkable merits (herz.leben). In order to determine the isolated effect of participation in the educational program, neglecting the possible impact of more intense care, this prospective multicenter randomized controlled study was designed (NCT00453037). METHODS: A total of 256 patients in 13 centers were enrolled and randomly assigned to 2 groups (G)...

Bcl-2/IgH rearrangements can be quantified in follicular lymphoma (FL) from peripheral blood (PB) by polymerase chain reaction (PCR). The prognostic value of Bcl-2/IgH levels in FL remains controversial. We therefore prospectively studied PB Bcl-2/IgH levels from 173 first-line FL patients who were consecutively enrolled, randomized, and treated within the multicenter phase 3 clinical trial NHL1-2003 comparing bendamustine-rituximab (B-R) with rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone...

A large majority of the currently diagnosed patients with hyperparathyroidism (PHPT) are mild or asymptomatic, mainly women after menopause. Following the debate held at the 16th European Congress of Endocrinology in Wroclaw (Poland) from May 3-7, 2014, arguments are here presented by a surgeon and a medical practitioner considering these situations rather have to profit from surgery, or simply from survey. For the trained endocrine surgeon, it is evident that parathyroidectomy confirms the diagnosis and undoubtedly reduces the discomfort felt by certain patients, prevents all risks of complications, removes patients and medical teams from the monitoring and represents a real individual financial benefit...

BACKGROUND: Insulinomas are rare neuroendocrine tumours (NETs) of the pancreas, characterized clinically by neuroglycopenic symptoms during periods of substrate deficiency. The gold standard test for diagnosing an insulinoma is a 72-h fast. However, the prognostic value of parameters in the standardized 72-h fast on histopathological tumour criteria and clinical presentation has not been examined. METHODS: In thirty-three patients diagnosed with an insulinoma records, and data were investigated retrospectively...

BACKGROUND: To describe a standardized, efficient, and cost-effective protocol for the diagnosis of temporary/persisting postoperative hypoparathyroidism after (total) thyroidectomy. METHODS: We included 237 consecutive patients who underwent (total) thyroidectomy without central neck dissection for various indications. Serum calcium (sCa) and intact parathyroid hormone (iPTH) levels were measured prospectively on the morning of postoperative day 1 to predict the long-term parathyroid metabolism...
