PTH has been reported to enhance steroid secretion in vitro from human adrenocortical cells and some reports indicate an increased cortisol secretion in patients with PHPT that normalizes after surgery. Thus, the possible stimulatory effect of PTH on cortisol secretion could contribute to the impairment of bone status in primary hyperparathyroidism (PHPT). The aim of this study was to evaluate the relationship between parameters of adrenal function, bone metabolism and ...

BackgroundThe management of post-operative recurrences of ACC remains controversial, although the current guidelines recommend a surgical approach whenever feasible with radical intent.AimThe aim of our study was to evaluate retrospectively the management of recurrences in patients with ACC. We collected data of 106 patients with ACC followed at the San Luigi Hospital for the management of recurrence. Median ...

Multiple Endocrine Neoplasia type 1 (MEN1) is an autosomal dominant inherited disease with a high degree of penetrance. The three most common locations of tumors are the parathyroid glands, the gastro-duodenum pancreas and/or the anterior pituitary gland. The gene involved in this disease is MEN 1, a tumor suppressor gene located on chromosome 11q13. The objective of our work was to describe the genotype of patients with MEN 1 born in Argentina.Subjects ...

Context: Patients with primary bilateral macronodular adrenocortical hyperplasia (PBMAH) usually present with bilateral benign adrenocortical macronodules at imaging and variable levels of cortisol excess. There is anecdotal evidence that, besides cortisol, other adrenal steroids, like mineralocorticoids, can be oversecreted.Objective: To assess the prevalence, clinical, biochemical characteristics and imaging features of aldosterone excess leading to pr...

Background/Introduction: Diabetic ketoacidosis (DKA) is a severe complication of diabetes mellitus type 1 (T1DM) with potentially life-threatening course. Data on patient knowledge about DKA in German-speaking countries is rare. Thus, we aimed to gather data about T1DM patients’ knowledge in terms of DKA.Methods: Together with two T1DM patients and an experienced diabetes counselor, we developed an anonymous questionnaire covering general knowledge ...

Background and objective: Optimization of glucocorticoid (GC) replacement therapy in adrenal insufficiency (AI) is crucial to avoid consequences of under- or overtreatment. Dosing of GC replacement is mainly based on clinical grounds; however, the impact of patient’s characteristics on daily GC requirement is poorly evaluated. The aim of the study is to assess the influence of sex (M/F) and BMI on dosing GC in patients with AI of different etiology....

The relation between androgen receptor (AR) gene amplification and other mechanisms behind castration-resistance in prostate cancer, such as increased expression of constitutively active AR variants and steroid-converting enzymes have been poorly examined. Specific aims of this study were to examine AR amplification in treatment-naïve and castration-resistant prostate cancer (CRPC) bone metastases and to explore molecular and functional differences. AR gene amplification ...

Introduction: Calcitriol-mediated hypercalcemia is one of the most common paraneoplastic syndromes associated with lymphoma.Aim: Evaluate clinical and biochemical manifestations as well on the management of hypercalcemia in patients with lymphoma.Materials and methods: Prospective analysis of patients with lymphoma who developed hypercalcemia during September-2011 and January-2016.Results: Two hundred and six...

Background: Pituitary adenomas (PA) and pheochromocytomas/paraganglioma (pheo/PGL) can occur in the same patient due to coincidence or of shared pathogenesis. There is evidence that, at least in some cases, classical pheo/PGL predisposing genes, may also play a role in pituitary tumorigenesis. A new condition called ‘the three P Association’ (3PAs) for the combination of PA with pheo/PGL has been recently described in patients with or without succinate dehydrogenase ...

Introduction: The possible change in the pattern of hormonal secretion by pituitary tumours is a very intriguing issue indeed, notably in the case of corticotroph-cell adenomas.Methods/design: We retrospectively reviewed the records of 1259 consecutive endoscopic endonasal surgical procedures for pituitary adenomas from 1998 to 2013. Of these, 132 were ACTH-secreting adenomas associated with Cushing’s disease (CD) and 44 were silent corticotroph-cel...
