Acromegaloidisms are usually reported as isolated cases that are not well characterised clinically. Indeed, most such cases were reported several decades ago, part of the reason why our knowledge about this entity is scarce. By contrast, clinical situations suggestive of acromegaly are not so infrequent, in which basal GH and IGF1 levels lie within a normal range, the GH responses to OGTT challenge are conserved and there is no radiological (MRI) evidence of hypothalamic-pitui...

Acromegaloidism includes clinical features of acromegaly with GH and IGF1 normal levels at baseline and dynamic, without findings of extrapituitary or pituitary tumour. It has been associated with various conditions without a definite pattern. The aim was to evaluate whether there are differences in some hormonal pituitary axis from acromegaloid subjects with respect to acromegalic and healthy subjects. We designed a comparative, multicenter, case–control study in three h...

Acromegaloidism is a very rare entity (have been 54 cases reported worldwide) that presents with clinical acromegaly and normal somatotropic axis, without findings of pituitary or extrapituitary tumour. Its origin has not been clearly established, although it is associated with several pathophysiological conditions. The local ethics committee approved to perform an observational and multicenter study in three hospitals from a region with approximately 800 000 people over 18 ye...

Hemoglobin A1c (HbA1c) is used for the long-term management of patients with diabetes mellitus (DM). Hemoglobin variants other than HbA1c and e-N-lysine-glycated HbA0 may cause analytical interference in determinations of HbA1c. Hemoglobin J is an abnormal hemoglobin, an alpha globin gene variant and present in various geographic locations. Hemoglobin J (depending on its type) has different characteristics and functions. For example hemoglobin J Capetown (α2 92Gln β2...

Background: the treatment of individuals with type 1 diabetes (T1D) has significantly evolved in recent years. Therefore, with the aim of achieving glycaemic targets to prevent or slow down the progression of the disease and its complications, hybrid closed-loop systems (AID) have been developed. These systems integrate three components: a continuous real-time glucose monitor, a control algorithm and an insulin pump. The objective of this study is to analyse the glycaemic and ...

Introduction: The global patterns of aberrant DNA methylation in thyroid cancer are not known. In this study, we have used DNA methylation arrays to determine, for the first time, the genome-wide promoter methylation status of different subtypes of thyroid tumors.Material and methods: We analyzed a cohort of 54 snap frozen thyroid samples (thirteen papillary tumors, six follicular, eleven anaplastic, twenty medullar and four normal tissue samples). Also ...

Background: Up to 15% of pheochromocytomas are malignant. The only definite criterion for malignancy is the presence of metastases. The histological differentiation between benign and malignant tumours is difficult, being a challenging problem nowadays.Aim: To asses if postoperative histological evaluation using the previously proposed pheochromocytoma of the adrenal gland scales scored (PASS) can predict malignancy.Methods: Twenty...
