Background: The expression and/or co-expression of somatostatin (sstr1–5) and dopamine (DR) receptors in neuroendocrine tumors (NETS) is of clinical interest as their expression implies that NETS could be treated with combined targeted therapy. In addition, the expression of sstrs permits tumour visualization with radiolabelled sst analogs (111In-DTPA-OctreoScan).Methods: We analyzed preoperative Octreoscans findings (also graded for the ...

Objective: The prevalence of metastatic bone disease in patients with neuroendocrine tumours (NETs) and their response to first line treatment with biphosphonates.Methods: We studied 271 patients (141 females) with NETs: 54 gastric, nine duodenal, 102 pancreatic, 29 small intestine, 29 appendix, 14 colon, 15 lung, one thymic, 20 unknown primary and ten elsewhere. Since September 2012 all patients with NETs and bone metastases were recruited to receive 4 ...

Introduction: Gonadotrophin-producing pituitary adenomas are usually non-functioning masses, and are not associated with elevated serum gonadotrophins. Functioning LH-producing gonadotroph pituitary adenomas are exceedingly rare in males, causing elevation of serum testosterone.Case report: We present an adult male who has been admitted to the emergency department a comatose state. Brain MRI revealed a large, lobulated mass of 6 cm caudal and 7.8 cm late...

Graves’ orbitopathy (GO) is an auto-immune disorder that targets intra-orbital tissues. It is well proven to involve inflammatory hypertrophy of the rectus EOMs. Superior oblique (SO) muscle has been sporadically reported to be involved in GO. However, there are extremely few reports in the literature that refer to the involvement of the inferior oblique (IO) muscle and here we present such a case.A 33-year-old man with unilateral exophthalmos was r...

Background: Clinical evaluation of Graves’ orbitopathy (GO) is often insufficient. Frequently it is difficult to decide whether a case of GO is active, or to detect the degree of severity. STIR sequence MRI suppresses signal from fat and thus in the orbits can also detect active inflammation and oedema of extra-ocular muscles (EOMs). The aim of the present study is to examine whether imaging of rectus EOMs with STIR MRI could provide additional information for the activit...

Introduction: The molecular pathogenesis of pancreatic neuroendocrineneoplasms (PNEN) is increasingly yet incompletely understood. PNEN typically occur sporadically or may occur within the context of hereditary tumor predisposition syndromes. PNEN can also be associated with endocrinopathy of hormonal hypersecretion. We present a young male with a multi-hormonal neuroendocrine neoplasm of pancreas.Case presentation: A 24-year-old male, non-smok...

Aim: To describe the clinical course of an adolescent girl with gigantism.Background and methodsIn young persons with open epiphyses, overproduction of GH results in gigantism, with consequent longitudinal growth acceleration1. Pituitary gigantism is extremely rare, and its cause in the majority of patients is a pituitary adenoma1. Here, we present a 12, 5 years-old girl investigated for tall stature [183.5&#1...

Introduction: Some endocrine disorders, including hypophysitis and isolated adrenocorticotropic hormone (ACTH) deficiency, are caused by an autoimmune response to endocrine organs. Previous data have also shown that isolated ACTH deficiency may be associated at least in part with a paraneoplastic syndrome. We present a rare case with isolated ACTH deficiency along with ectopic posterior hypophysis.Case presentation: A 53-yea...

Background: Adrenal venous sampling (AVS) is the gold standard method that evaluates the source of aldosterone overproduction in primary aldosteronism. During AVS aldosterone and cortisol are simultaneously measured in order to assess successful adrenal cannulation and lateralization of aldosterone overproduction. However, in patients with both adrenal cortisol and aldosterone overproduction, plasma metaneprhines and normetanephrines can be measured to overcome selectivity and...

Introduction: Limited data, support the notion that testosterone induces oxidative stress. Corticotropin-releasing hormone (CRH) participates locally in the endothelial inflammatory response by regulating the pro-oxidative mechanisms of the endothelium, inducing its adaptation to local stress. The present study was undertaken to determine whether the CRH induced pro-oxidant activity in macroendothelial cells under basal conditions, is regulated In vitro by androgen (t...
