Parathyroidectomy for hyperparathyroidism can be complicated with development of Hungry Bone Syndrome (HBS), a constellation of profound hypocalcemia with hypomagnesemia and hypophosphatemia. The severity of this potential life-threatening condition is related to the extent of the parathyroid-mediated high-turnover bone disease. We present a case of a 59-year-old woman developing post-surgical HBS as a result of longstanding severe unrecognized primary hyperparathyroidism (PHP...

Background: Ectopic Cushing’s syndrome (ECS) frequently represents a diagnostic challenge due to its complex clinical presentation.Case presentation: A 57-year-old male presented with typical Cushingoid appearance, high adrenocorticotropic hormone (ACTH) level (138.3 pg/ml), lack of cortisol circadian rhythm and suppression in overnight 1 mg dexamethasone suppression test (DST) (1374 nmol/l). Great daily fluctuation of serum cortisol levels from ver...

Personalized medicine is a crucial part of modern medicine. As a result, other therapeutic options apart from levothyroxine are considered when treating hypothyroidism. Desiccated thyroid pharmaceuticals, that in addition to thyroxine (T4), contain triiodothyronine (T3), are one of them. ETA recognized the rapid use of desiccated thyroid pharmaceuticals and described specific guidelines for its utilization. The biggest problem of their use is unresolved issues of content that ...

Background: Although adrenal vein sampling (AVS) is a technically demanding procedure, it is still considered the gold standard for subtyping primary aldosteronism (PA). The aim of the study was to analyze the success rate of AVS in patients with PA.Methods: In all patients AVS was performed sequentially during continuous stimulation with adrenocorticotrophic hormone by one interventional radiologist. Adrenal vein cannulation was considered successful if...

Background: Tumor-associated macrophages (TAMs) with dysregulated inflammatory phenotypes play a key role in carcinogenesis. In thyroid carcinoma (TC), excessive release of proinflammatory cytokines decreases the expression of sodium-iodine transporter and inflammation potentiates tumor progression.Aim: To assess the impact of TC cells on the functional reprograming of TC-induced macrophages at the level of transcriptome and metabolic pathways, and asses...

The somatostatin receptor 5 (sst5) and its truncated splicing variants (sst5TMD5, sst5TMD4) are considered putative biomarkers that can predict pharmacological response or aggressiveness in several endocrine-related pathologies, such as acromegaly. sst5 is encoded by a gene, SSTR5, that lacks introns within its coding sequence, and hence, the splicing variants identified are generated by non-canonical splicing events. However, the mechanisms underlying their genesis a...

Adjuvant treatment for post-menopausal women with early breast cancer (BC) includes aromatase inhibitors (AI), known to decrease bone mineral density (BMD). In this study, we investigate whether denosumab is a valid second option for patients unable to receive standard adjuvant i.v. zoledronic acid (ZA). In total, 212 patients have been evaluated after they did not receive ZA. Of those 194 were included. After evaluation by an endocrinologist, all patients were offered ZA as t...

Introduction: In Endocrinology, subclinical disorders meet certain diagnostic laboratory thresholds, but are by definition asymptomatic. Subthreshold disorders in Endocrinology have not been defined. We describe two cases of cortisol deficiency, primary and secondary, with normal baseline cortisol, which were by presentation clinical, but could be characterized as subthreshold by biochemical cut-off criteria.Case 1: A 47-year-old woman was referred for a...

Introduction: tests alternative to the fasting test are necessary for the diagnosis of numerous causes of non-diabetic hypoglycaemia (NDH), that not provoked by starvation (postprandial hypoglycemia), such as insulin autoimmune syndrome (IAS) and noninsulinoma pancreatogenous hypoglycemia syndrome (NIPHS). However, there is no consensus on the most optimal test (prolonged oral glucose tolerance test (pOGTT) or mixed meal test (MMT)) in this cohort of patients.<p class="abs...

Introduction: Decreased glycemia in patients without diabetes mellitus (nondiabetic hypoglycemias; NDH) is a manifestation of severe diseases from endocrinopathies to malignant tumors. The most specific symptom of NDH is association of attack with the intake of carbohydrate-containing food. Hypoglycemia is usually manifested by neurological and mental disorders, and therefore, patients initially seek medical help not from an endocrinologist, but from psychiatrists and neurolog...
