Introduction: Autoimmune thyroid diseases, including Graves’ disease (GD) and Hashimoto’s thyroiditis (HT), are complex diseases combining genetic susceptibility and environmental encounters leading to the breakdown of immune tolerance. The relationship between thyroid cancer (TC) and HT has been proven (Guarino et al. 2010), and the antibody specific association has been demonstrated (Azizi et al. 2014). Overexpression of claudin-1 appears to be an...

Thyroid dysplasia (ectopy, hypoplasia or aplasia) is a common cause of congenital hypothyroidism. Lingual thyroid is a rare embryological aberration caused by failure of migration of the thyroid gland to its normal position in the neck.This retrospective study involved 30 patients with lingual thyroid diagnosed in our Department between 1970–2005. The diagnosis was based on physical examination, evaluation of the mental development (IQ) and following tests:TSH, fT4, ultra...

Pancreatic neuroendocrine tumors (PNETs) form a distinct entity of malignant lesions with a dreadful prognosis. More than 50% of the patients already have distant metastasis by the time of diagnosis, which underpins the urgent need for more effective treatment modalities. Notch pathway, evolutionary old and highly cellular context dependent signalling mechanism, was shown to regulate growth and development of normal neuroendocrine cells and PNETs, with experimental data implyi...

Introduction: Neurofibromatosis type 1 (NF1) is one of the most frequent genetic dominant syndrom in men with a prevalence of 1 in 2600 to 3000 individuals worldwide. NIH NF1 diagnostic criteria are driven by the most frequent manifestations of the disease (café au lait macules (CAL), neurofibromas, freckling, optic glioma, Lisch nodules and osseus lesions). There are many clinical manifestations of NF1 (neurological, cardiovascular, gastrointestinal, endocrine and orthop...

Introduction: Pheochromocytoma and paraganglioma (PPGLs) are rare neuroendocrine tumors. Some of them are catecholamine-secreting tumors responsible for hypertension or adrenergic symptoms. Among 10% are malignant with a higher rate of malignancy in the inherited syndromes. Management of patients with hereditary pheochromocytoma and PPGLs is well defined and standard treatment is surgical resection.Case report: We report the case of a 53-year-old man who...

Peptidyl growth hormone secretagogues (GHS), including ghrelin and growth hormone releasing peptides (GHRPs), have been reported to exert cardioprotective effects in experimental models of ischemia-reperfusion (I/R) injury through GH-independent pathway. Along this line, we have identified CD36 as a main target for GHRP binding and action in the heart. Yet, not much is known regarding the molecular mechanisms of the cardioprotective effects of GHRPs. The objective of this stud...

In female mammals, the timing of the preovulatory LH surge depends on the combination of the positive estrogen feedback and a circadian signal which synchronizes the LH surge with the transition between the resting and active period at the end of the follicular phase, when arousal is maximal. Previous results have demonstrated that a functional biological clock, located in the suprachiasmatic nucleus (SCN), is required for optimal female fertility. In this context, we have inv...

Introduction: Pregnancy in women with pre-existing Type 1 diabetes (T1DM) is known to carry a 3–5 times increased frequency of severe hypoglycaemia (SH) in the first compared to the third trimester. The main predictors are: pre-gestational SH, HbA1C <6.5%/48 mmol/mol, duration of diabetes and higher total daily insulin doses. Freestyle Libre or flash monitoring utilizes a 14 day tiny glucose sensor which is applied to the back of the arm and scanned with a reader, to ...

Introduction: Th17 cells and their hallmark cytokine IL-17A were reported to be involved in the development of autoimmune orchitis and encephalomyelitis by impairing the integrity of the blood–testis and blood–brain barrier integrity and by inducing local inflammation. However, the role of IL17A in autoimmune thyroid disease is still debatable.The aim of our study was to estimate immunoexpression of IL-17A in the thyroid tissue of patients with...
