Hemoglobin A1c (HbA1c) is formed from the addition of a glucose residue to the N terminus of the Beta chain of a hemoglobin molecule via a non-enzymatic glycation pathway. Its levels correlate with the ambient plasma glucose concentration. The 120-day life span of red blood cells makes HbA1c a useful tool to approximate the diabetic control of patients over three to four months. It has also been found to be an accurate predictor of the microvascular and macrovascular complicat...

Introduction: Silent somatotroph Pituitary Neuroendocrine Tumours (PitNETs) are extremely rare (2−3% of surgically treated pituitary tumours) and data on their natural history and outcomes are scarce.Aim: To review systematically the cases of these tumours presenting in our Centre.Patients and methods: Patients with this diagnosis were identified from our Pituitary Registry and clinical/laboratory/imaging data were collected ...

Background: Metastatic disease in the pituitary (PM) is uncommon and the published literature mainly involves case reports and small case series. We aimed to analyze presenting manifestations and outcomes of patients diagnosed with PM in our pituitary centre.Methods: Retrospective review of our Pituitary Registry to identify patients with PM from 2006 to present. Clinical, radiological, and pathological data were collected and analysed.<p class="abst...

Introduction: Functioning gonadotroph adenomas (FGAs) are very rare tumours secreting biologically active gonadotropins. In males, typically, FSH levels are elevated, whereas LH and testosterone are variable. Herein, we present three males with elevated, normal or low testosterone at diagnosis.Cases: Case 1:42-year-old man with two-year history of visual impairment. Bitemporal hemianopia was confirmed. Imaging showed macroadenoma compressing optic chiasm...

BackgroundIncreasing incidence of thyroid cancer together with improved prognosis raises a concern regarding development of second primary cancers. Moreover, little is known about the incidence of thyroid cancer as a second primary neoplasm after other cancers.MethodsA cohort of 39002 people (356034.5 person years) with primary thyroid cancer was identified in 13 population-based cancer registries in Europe, ...
