Wearable physical activity monitors are growing in popularity as they provide the opportunity for self-monitoring, real time data collection and data sharing for cardiovascular and sports medicine. However, there are discussions about the accuracy of their energy expenditure estimate. This study examined and compared basal metabolic rate through indirect calorimetry and through wrist-worn devices and bioimpedance. The group consisted of 30 healthy male individuals, professiona...

Introduction: Thyroid amyloidosis is defined as amyloid protein and fat deposition within the thyroid gland. It is classified as either primary (idiopathic) or secondary to inflammatory/chronic disease. Albeit deposition of amyloid protein in thyroid tissue is frequent, amyloidosis affecting exclusively the thyroid gland without evidence of other organs involved is extremely rare. We report a clinical case of a patient who underwent lobectomy due to a toxic adenoma, whose hist...

The Sodium Iodide Symporter (NIS) is responsible for active transport of iodide into thyroid cells. Its expression in thyroid tumors allows the use of radioactive iodine (131I) as co-adjuvant therapeutic tool to eliminate remaining tumor cells and metastases after total thyroidectomy. Nevertheless, certain subsets of patients with advanced forms of thyroid cancer lose the ability to respond to radioiodine therapy, which drastically reduces their survival rates. Recent studies ...

Neuroendocrine neoplasia (NENs) are rare tumours that show features of neuroendocrine differentiation. Generally, NENs can be subdivides into high-grade neuroendocrine carcinomas (NECs) and low-to-intermediate grade neuroendocrine tumours (NETs). The most common Endodermal NETs’ localisations are the lungs, ileum, appendix, and rectum. Neuroectodermal NETs include medullary thyroid cancer (MTC), pheochromocytoma (PHEO), and paraganglioma (PGL). Nets are estimated to occur...

Thyroid dysfunction has been traditionally related to several lipid abnormalities. Indeed, even within the normal range of thyroid-stimulating hormone (TSH) values, a linear increase in total cholesterol, low-density lipoprotein cholesterol and triglycerides and a linear decrease in high-density lipoprotein cholesterol (HDL-C) levels has been observed with increasing TSH. With respect to serum high-density lipoprotein (HDL) cholesterol concentrations, high, normal, or low valu...

Introduction: There is circumstantial evidence supporting a role of growth hormone and insulin-like growth factor 1 in the development and progression of tumors. Endosalpingiosis is characterized by the presence of non-neoplastic fallopion tube-like epithelium in ectopic anatomical locations.Case report: A 45-year-old woman presented with a constant moderate to intense perianal pain limiting basic daily life activities. She also complained about pain at ...

Aim: Stimulated thyroglobulin (sTg), measured at radioiodine remnant-ablation (RRA) in patients with differentiated thyroid cancer(DTC), is an important predictive factor of persistent disease. However, Tg produced by normal thyroid cells may also contribute to the sTg value.We aimed to study the relationship between sTg-level in RRA and the thyroid remnant size (TRs), using post-therapy whole-body scan (131I-ptWBS), at different TSH stimulation method.<...

IntroductionThe Sodium Iodide Symporter (NIS) is responsible for the active transport of iodide into thyroid cells. Most of differentiated thyroid carcinomas (TC) retain the functional expression of NIS, which allows the use of radioiodide (RAI) as the systemic treatment of choice for metastatic disease. Still, a significant proportion of patients with advanced thyroid cancer fail to respond to RAI therapy (refractory-TC), which makes their management ve...

Introduction: The management of small size (≤ 1 cm) papillary thyroid carcinoma, also known as papillary thyroid microcarcinoma (PTMC) is a debated topic as it includes tumors with a wide range of biological characteristics and behavior.Objectives: To describe prevalence, clinical and histological characteristics of PTMC with excellent response to treatment after a median follow up of 9.85±6.21 years.Methods: We did a re...

Introduction: Ogilvie’s syndrome (acute colonic pseudo-obstruction) is a syndrome in which the clinical features resemble those of mechanical obstruction with massive colonic dilatation, in the absence of any demonstrable evidence of such an obstruction in the intestine. The exact pathophysiology of intestinal pseudo-obstruction remains to be elucidated. Current theories continue to suggest the idea of an imbalance in the autonomic nervous system. The initial therapy rema...
