Background: The importance of carcinoembryonic antigen (CEA) assessment in the evaluation of medullary thyroid carcinoma is well known. The role of CEA in the assessment of other neuroendocrine tumors (NET) is not clear. We aimed to evaluate a possible correlation between CEA measurements and the aggressivity of NETs.Methods: We evaluated 56 (36 women) NETs followed in a tertiary center (23 gastrointestinal, 12 pancreatic, 10 pulmonary, 7 without primary...

The ingestion of marine foods is a potential route of contamination by tributyltin (TBT), a biocide organotin used as an antifouling in boat paints. TBT causes a phenomenon known as imposex, that induces, for instance, the irreversible appearance of male sexual characteristics in gastropod females. In mammals, TBT also directly impairs the sexual development. In fact, it is known that TBT can affect women in reproductive age. Our aim was to study whether the maternal exposure ...

Obesity is a multifactorial disease in which environmental conditions and genetic factors play an important pathogenic role [1]. Interestingly, some of these obesogenic environmental and genetic conditions are shared with neurodegenerative diseases (NDD). The common biological mechanisms involved in obesity and NDD are insulin resistance, pro-inflammatory cytokines, and oxidative damage, in turn leading to cognitive dysfunction or cell death. In this aspect, a poly-pharmacolog...

Background: Resistance to thyroid hormone beta (RTHβ) is an inherited syndrome of reduced tissue responsiveness to thyroid hormones (THs). It is driven in 85% of cases by mutations in the thyroid hormone receptor beta (THRb). The estimated incidence is 1:40.000 to 1:19.000 live births. We report the clinical, laboratory, and genetic analysis of a patient with this disorder.Case report: A 12-year-old boy with a history of Attention-Deficit/H...

Introduction: Endogenous Cushing syndrome (CS), is associated with significant morbidity (metabolic, cardiovascular, bone, psychiatric complications among others). Most complications tend to improve if hypercortisolism is controlled but some are only partially reversible or even experience temporary exacerbation.Patients and Methods: We report 2 cases of adrenal Cushing Syndrome (CS). The first is a 72 years-old female with CS caused by bilateral macrono...

Post-surgical hypoparathyroidism occurs as inadvertent removal or irreversible damageparathyroid disease, irreversible or permanent causing decreased action of parathormone leading to hypocalcemia and hypophosphatemia.Clinical Case: A 52-year-old woman referred from our outpatient clinics due to severe hypocalcemia symptomatic; hand and foot cramps, and hyperphosphatemia: albumincorrected calcium. (5.52 mg/dl and phosphate of 6.6 mg/dl). She presents a h...

Introduction: Hyponatremia, defined as a serum sodium concentration below 135 mEq/l, has a heterogeneous etiology, the main endocrine causes includind the syndrome of inappropiate antidiuresis (SIAD), adrenal insufficiency and severe hypothyroidism.Materials and methods: Clinical, hormonal and imaging evaluationAim: To present a case of hyponatremia leading to the diagnosis of a large pituitary tumorCase pres...

Introduction: Intrasellar arachnoid cysts are rare and clinically resemble nonfunctional pituitary adenomas. Arachnoid cysts should be considered in the differential diagnosis of cysts developing in the sellar region, together with cystic pituitary adenoma, craniopharyngioma, epidermoid cysts, and Rathke’s cleft cysts. Symptomatic cysts are operated but can recurr.Case presentation: We present 2 cases of compressive intrasellar arachnoid cysts occur...

Introduction: Acromegaly is a rare disease usually caused by growth hormone (GH) secreting pituitary adenomas (PA) and associated with a series of complications, including tumours. The most prevalent tumour types are colonic adenomas, colorectal cancer (1) and nodular goiter (2). We present two acromegaly cases attending our center that associate cervical cancer and another that associates melanoma. Clinical cases: Case 1: A 56-yea...

Introduction: Syndrome of inappropriate secretion of thyrotropin (SITSH) is a rare condition characterized by uninhibited serum TSH in the presence of high thyroid hormones, usually caused by TSH secreting adenoma or resistance to thyroid hormones (RTH). Differential diagnosis between the two is often challenging due to their overlapping features.Case report: We present the case of a 50-year-old postmenopausal woman with a history of -myocardial infarcti...
