Introduction: Adrenal vein sampling (AVS) is a gold standard in the assessment of the cause of primary aldosteronism (PA). It is technically demanding procedure having the high rate of failure, even in expert centres. Our study aimed to investigatewhether the data on aldosterone and cortisol concentration from successfully cannulated adrenal vein could determine the subtype of PA in certain patients with partially successful AVS.Materials and methods: Th...

Introduction: The widespread use of neuroimaging leads to the increased detection of asymptomatic pituitary adenomasnot causing significant mass effect. Their optimal management remains unclear.Aim of the study: To explore the natural course of incidentally found nonfunctioning pituitary macroadenomas.Patients and Methods: This was a longitudinal study that enrolled patients with clinically nonfunctioning pituitary macroadenomas wh...

Background: Radiotherapy (conventional and/or radiosurgery) is an effective treatment option in patients with acromegaly when biochemical control of the disease cannot be achieved by medication and/or surgery. Purpose: The aim of our study was to evaluate the efficacy of gamma-knife radiosurgery or conventional radiotherapy in the treatment of GH-secreting pituitary adenomas.Materials and methods: We conducted a retrospective analysis of 22 acromegaly pa...

Aim: In this study we have compared the adequacy rates of FNA samples between more experienced and less experienced operators in thyroid FNA.Introduction: The prevalence of thyroid nodules is estimated to be about 4–7%, increasing up to 50% in the adult population. US guided FNA has become the preliminary investigation of choice for thyroid nodules, as it is widely available and has been proven to increase diagnostic efficacy....

Soy phytoestrogens (PE) have been shown to improve insulin resistance and lipids but may adversely affect thyroid function.Objective: To determine the effects of soy PE on thyroid function, insulin resistance and lipid parameters in patients with subclinical hypothyroidism.Design: A randomised, double-blind, crossover study was undertaken involving 60 patients with subclinical hypothyroidism. Patients were randomly assigned to eith...

Acromegaly is a complex disease with an insidious onset and diagnosis can be delayed. The aim of the study was to investigate the diagnostic delay (DD), for patients with acromegaly due to a pituitary tumour in Sweden. Data were obtained from the Swedish National Patient Register. Patients diagnosed between January 1, 2011 and December 31, 2013 in Sweden were included (n=135, 69 men, 66 women). For these patients, the occurrence of pre-defined relevant comorbidities w...

Acromegaly and comorbidities incur large costs in the Swedish health care system. The aim of the study was to describe direct costs since time of diagnosis, for patients with acromegaly due to a pituitary tumour in Sweden. Data were obtained via linkage of nationwide registers. Patients diagnosed between 1 July 2005 and 31 December 2007 in Sweden and with a follow-up of at least 6 years were included (n=105). Direct costs due to use of health care resources and pharma...

Background: Neuroendocrine tumours (NETs) are a rare and heterogeneous group of neoplasms that mainly originate from the gastroenteropancreatic tract (GEP-NETs). The vast majority of NETs tend to overexpress somatostatin receptors (SSTRs), which can be targeted by somatostatin analogues (SSAs). 68Gallium DOTA SSTR peptide positron emission tracer computed tomography (68Ga PET-CT) has emerged as superior to other imaging modalities in identifying SSTRs. Th...

Background: Pancreatic neuroendocrine tumours (panNETs) are rare tumours (prevalence 4/100,000). Diagnosis and staging of panNETs requires biochemical screening, cross-sectional imaging (with CT/MRI), endoscopic ultrasound (EUS) and where available, functional imaging using 68Ga-labelled synthetic octreotide analogues using PET-CT due to its reported higher sensitivity and specificity.Methods: A retrospective, electronic case note study was ca...

Background: Pancreatic neuroendocrine tumours (panNETs) may arise as part of an underlying genetic condition such as multiple endocrine neoplasia type 1 (MEN type 1). The value of functional imaging using 68Ga-labelled synthetic octreotide analogues using PET-CT has not been extensively evaluated in patients with MEN1 to determine its value.Methods: We investigated the effect of 68Ga-based PET-CT imaging on patient management in pat...
