Autosomal dominant hypocalcaemia: identification of two novel variants of gene.

Autosomal dominant hypocalcaemia is a rare aetiology of hypocalcaemia, caused by gain-of-function mutations of the calcium-sensing receptor () gene. We present two cases of two asymptomatic women (50-year-old-case 1 and 25-year-old-case 2), referred to our endocrinology department for investigation of hypocalcaemia, hyperphosphatemia and inappropriately low parathormone. Both patients had relatives with the same laboratorial findings.

New-onset diabetes after kidney transplantation: Incidence and associated factors.

Aim: To determine the incidence and associated factors of new-onset diabetes after transplantation (NODAT) in a Portuguese central hospital.

Methods: This single-center retrospective study involved consecutive adult nondiabetic transplant recipients, who had undergone kidney transplantation between January 2012 and March 2016. NODAT was diagnosed according to the criteria of the American Diabetes Association.

Rare and severe complications of congenital adrenal hyperplasia due to 21-hydroxylase deficiency: a case report.

Introduction: We report the case of a patient with classical congenital adrenal hyperplasia due to 21-hydroxylase deficiency who presented with unusual anatomical and biochemical features, namely massively enlarged adrenal glands, adrenogenital rest tissue and an unexpected endocrine profile. The contribution of the adrenocortical cells in the adrenals and testicles was determined by a cosyntropin stimulation test before and after adrenalectomy. To the best of our knowledge this is the first report of such a case in the literature.

Molecular characterization of parathyroid tumors from two patients with hereditary colorectal cancer syndromes.

The tumor suppressor adenomatous polyposis coli (APC) has recently been implicated in parathyroid development. We here report clinical, histopathological and molecular investigations in parathyroid tumors arising in two patients; one familial adenomatous polyposis (FAP) syndrome patient carrying a constitutional APC mutation, and one Lynch syndrome patient demonstrating a germline MLH1 mutation as well as a non-classified, missense alteration of the APC gene. We sequenced the entire APC gene in tumor and constitutional DNA from both cases, assessed the levels of APC promoter 1A and 1B methylation by bisulfite Pyrosequencing analysis and performed immunohistochemistry for APC and parafibromin.

Plasma corticotropin releasing hormone during the feeling of induced emotions.

Objectives: Central neuropeptides modulate behaviour. Plasma levels of neuropeptides may reflect central levels due to specific brain-to-blood transport systems. We purposed to show the modulation of plasma corticotropin releasing hormone (CRH) levels in relation to induced emotions.
