Introduction: Apart from occurring sporadically, insulinoma within the framework of multiple endocrine neoplasia 1 (MEN-1) is well known. The rare presence of multifocal insulinomas has recently been assigned a separate entity (insulinomatosis). The difficulty of localising insulinomas may be improved by GLP1-receptor imaging.Case report A 48-year-old woman had been treated for suspected epileptic seizures for 2 years (lamotrigine). During another such e...

Purpose: We aim at prospectively comparing the detection rate of GLP1-R PET/CT vs GLP1-R SPECT/CT vs standardized contrast enhanced 3T-MRI in patients with suspected insulinoma.Methods: 40 patients with neuroglycopenic symptoms due to endogenous hyperinsulinemic hypoglycemia were enrolled.3T-MRI was performed. Afterwards patients received SPECT/CT after injection of 111In-DOTA-exendin-4 and PET/CT after injection of <sup...

Purpose: The aim of our study is to compare the detection rate of GLP-1R PET/CT and GLP-1R SPECT/CT in patients with a biochemically proven endogenous hyperinsulinemic hypoglycemia. Preliminary results of an ongoing study are reported.Methods: Thirty-three patients (25 females, 8 males, age range 18–80 years, mean 49 years) with neuroglycopenic symptoms due to endogenous hyperinsulinemic hypoglycemia were enrolled (ClinicalTrials.gov, NCT02127541).<...

Context: Surgical intervention is advised in patients with multiple endocrine neoplasia type-1 (MEN-1) with non-functioning pancreatic neuroendocrine tumors (PanNET) and a size ≥20 mm. However, functioning PanNET such as patients with endogenous hyperinsulinemic hypoglycemia (EHH) due to (one or multiple) insulinomas should be treated surgically independent of size. Reliable preoperative localization of insulinomas is critical for surgical strategy.<p class="abstext"...

Introduction: Surgery is often the only treatment option that can effectively treat patients with insulinoma in MEN-1. However, the surgical intervention should be limited as surgery can not cure patients with MEN-1. It is, therefore, mandatory to correctly localize insulin secreting tumors from other neuroendocrine tumors.Materials and Methods: In this report we include 6 patients with proven endogenous hyperinsulinemic hypoglycemia and neuroglycopenia ...

Purpose: We aim at prospectively comparing the detection rate of glucagon-like peptide 1 receptor (GLP1R) PET/CT vs GLP1R SPECT/CT vs standardised contrast enhanced 3T MRI in patients with endogenous hyperinsulinaemic hypoglycaemia.Methods: 14 patients with neuroglycopenic symptoms due to endogenous hyperinsulinaemic hypoglycaemia were already enrolled (mean age 56 years, ten females and four males). A standardized contrast enhanced 3T MRI was performed....

Adrenocortical carcinoma (ACC) is a rare endocrine cancer with a poor prognosis. Roughly 10–15% of all ACCs arise in patients with a predisposition to cancer development due to a germline mutation. Pediatric ACC is a well-described core malignancy of the Li Fraumeni syndrome tumour spectrum. More recently TP53 mutations have also been found in adult ACC patients. In addition recent advances in clinical and molecular genetics have identified additional familial ca...

A biobank is a repository that stores biological samples (usually human) for research. Samples comprise a range of tissues, of which the most common are blood samples. The latter are often separated into different constituents such as serum, DNA and RNA extracts at the time of initial collection. Cell lines can also be generated, thereby perpetuating material for DNA and related analyses. Generally, biological samples are stored in biobanks as part of a protocol pertaining to ...

Hypocalcaemia is a common presentation to the emergency department; patient’s symptoms vary but typically report pins and needles and muscle cramps, due to neuromuscular irritability. Other important features include ECG changes (prolonged QTc) and seizures. The most common causes are hypoparathyroidism, vitamin D deficiency and chronic kidney disease.A 25-year old male presented with symptomatic hypocalcaemia who was referred to us for follow up, a...

The question posed by this title encompasses three issues. First, certain endocrine diseases present physiologic challenges to high-intensity or endurance activities, including type 1 diabetes mellitus and adrenal insufficiency. Using carefully adjusted insulin regimens evolved in concert with training sessions, several athletes with type 1 diabetes have succeeded in elite competitions, but the endocrinologist must ‘train with the athlete’ and craft regimens that con...
