Metastatic Neuroendocrine Tumor (NET) to the pineal gland is a unique manifestation previously unreported in the literature. We describe an unusual case of metastatic bronchial NET to the pineal gland in a 71-year-old male patient. His primary NET had been resected six years previously and there was no indication of the presence of disseminated metastatic disease at that time. Due to increased uptake...
An overview of long-term clinical consequences of TSH suppressive therapy provides evidence that serum TSH levels should be maintained at levels <0.1 mU/l in high-risk (stage III and IV) patients, whereas lower-risk patients should be allowed to have their TSH levels rise into the normal range after residual disease has been ruled out by imaging and/or stimulated thyroglobulin measurement. The...
Early experiences can modify regulatory factors affecting gene expression in such a way that, although the DNA sequence itself is not changed, the individual’s physiology and behavior is substantially influenced. In some instances these epigenetic effects are exerted upon exposure, while in other instances they are transmitted across generations via incorporation into the germline. Examples of both...
OBJECTIVE As we previously demonstrated, the inhibitory effect of iodine on thyroid cell growth is mediated by iodolactones, especially 6-iodo-5-hydroxy-eicosatrienoic acid (δ-iodolactone). In this communication we compare the effect of iodide, molecular iodine and δ-iodolactone on growth inhibition and apoptosis on three human thyroid carcinoma cell lines (B-CPAP cells, FTC-133 cells and 8505C cells)...
Thyrotoxic Periodic Paralysis (TPP) is a rare manifestation of hyperthyroidism characterized by muscle weakness and hypokalemia. Thyroid-Stimulating Hormone (TSH)-secreting pituitary adenoma is a rare cause of hyperthyroidism. Even more rare is the occurrence of TPP as the first manifestation of a TSH-secreting pituitary adenoma. We report a 31-year-old Asian male patient suffering from TPP caused...
The central neuroendocrine systems are responsible for the control of homeostatic processes in the body, including reproduction, growth, metabolism and energy balance, as well as stress responsiveness. These processes are initiated by signals in the central nervous system, specifically the hypothalamus, and are conveyed first by neural and then by endocrine effectors. The neuroendocrine systems, as...
OBJECTIVE To compare the effects of various anaesthetics on stress response in the presence and absence of surgical stimulation. DESIGN Twenty-nine pigs scheduled to undergo surgical central vein catheter placement were randomly allocated to receive only sedation with ketamine-midazolam (group SHAM, n=5) or general anaesthesia with either propofol 8 mg/kg/h (group PROP, n=8), sevoflurane 1.0 MAC...
Thyroid hormones (THs) are required for normal brain and somatic development and for the proper regulation of physiology in both children and adults. Thyroid function is controlled by the dynamic interrelationships between the hypothalamus, the pituitary and the thyroid. These dynamic relationships maintain circulating levels of THs within a narrow range under normal conditions. Normally, there is...
Objective Autoimmune Thyroid Disease (AITD) results from an interaction of exogenous and endogenous factors in a genetically predisposed individual. AITD is being increasingly reported among the Indian population. Lymphocyte subsets and levels of interleukin-5 (IL-5) were studied in the peripheral blood of patients with AITD. Design Subjects diagnosed with either hyperthyroidism due to Graves’ Disease...
The aim of this review was to analyze the potential effects of environmental chemicals on homeostatic control related to glycemia and energy balance. Many of the environmental chemicals can mimic or interfere with the action of hormones and are generally referred to as “endocrine disruptors”. Among these compounds, polychlorinated biphenyls, dioxins, phthalates and bisphenol-A have been correlated...
Central Hypothyroidism (Central H) is mainly due to acquired lesions, either in the pituitary, the hypothalamus or both, and in such cases it is usually associated with deficient secretion of other pituitary hormones. Isolated central hypothyroidism (I Central H) remains a very rare disease. By the use of the serum Thyroid Stimulating Hormone (TSH) assay as an initial screening test for thyroid disease,...
OBJECTIVE: To evaluate the effectiveness of active parental involvement in a lifestyle intervention for the management of childhood obesity. DESIGN: Forty-two overweight children (32 girls and 10 boys), aged 9.2±0.2 years and with percent overweight 39.8±2.7%, were randomly allocated either to a child-and-parent group (N = 23) or a child-alone group (N = 19). Both groups attended a 3-month multidisciplinary...
OBJECTIVE: This study was undertaken to assess the accuracy of GlucoDay® — a portable detector of subcutaneous glucose — by comparing the results to those obtained by Biostator® an established and reliable method for continuous glucose measurement in whole blood. DESIGN: Subjects with type 1 diabetes (n:6), subjects with type 2 diabetes (n:6), and six healthy controls were studied for 24 hours; they...
Women present an estradiol-dependent cardiovascular risk profile. Based on various studies, it was considered that estrogen therapy (ET) in postmenopausal women could probably reduce the higher cardiovascular risk in this group. Assymetric dimethylarginine (ADMA) is an endogenous methylated arginine which inhibits nitric oxide (NO) synthesis by competing with the substrate of NO, L-arginine, leading...
OBJECTIVE: Insulin resistance is associated with aging and stress, both common among patients repeatedly failing to conceive with in vitro fertilization (IVF repeaters). In the present study we examined whether low-dose metformin could improve the outcome in IVF repeaters without polycystic ovary syndrome (PCOS). DESIGN: Study I was a preliminary clinical trial aiming at defining indications for therapy;...
Coexistence of differentiated thyroid cancer (DTC) and thyroid autoimmune diseases could represent a mere coincidence due to the frequent occurrence of autoimmunity, but there may also be a pathological and causative link between the two conditions. The coincidence of DTC with Hashimoto’s disease has been variably reported at between 0.5 and 22.5 % and of DTC with Graves’ disease between 0 and 9.8...
