Introduction: Dopamine agonists (DA) are first-line treatment for prolactinomas and effectively control hyperprolactinemia in most patients. However, side effects may negatively impact health-related quality of life; and post-withdrawal remission rates are low, resulting in prolonged DA treatment.Methods: Dutch multicenter prospective observational cohort study mapping standard care for 316 prolactinoma patients. Baseline clinical characteristics and tre...

Introduction: Patients with prolactinomas suffer from a wide range of symptoms, of which the effect on health-related quality of life (HR-QoL) needs further investigation. Moreover, the first-line treatment for patients with prolactinomas, dopamine agonists (DAs), albeit being effective in lowering prolactin levels, might further hamper HR-QoL due to side effects. To assess the impact of symptoms and treatment modality on HR-QoL, a cohort of patients with prolactinoma was cros...

Background: Pheochromocytoma is a rare adrenal tumor that can present with a variety of different symptoms. The cardinal symptoms are paroxysmal palpitations, headaches and sweating together with paroxysmal or persistent hypertension. Increasing use of CT scan contribute to the discovery of more adrenal incidentalomas and therefore more pheochromocytomas due to the workup of the incidentalomas. We intended to investigate if the presentation of the pheochromocytoma was differen...

J was born at term (2.62 kg). She presented aged six months with severe faltering growth, (weight 5.1 kg, length 57.3 cm, OFC 39.0 cm). Investigations showed elevated prolactin (1838 mIU/l) and undetectable IGF1 but were otherwise normal. Her karyotype was 46XX. A brain MRI was normal. By 11 months of age she had evident developmental delay and dysmorphic features (triangular face; hypertelorism; synophrys; broad nasal root; short nose with rounded tip; carp like mouth; short ...

The secretion of growth hormone (GH) is under the feedback control of numerous nutritional and endocrine factors. The most widely used endocrine dynamic tests used to diagnose GH deficiency, insulin hypoglycemia test, and glucagon test, are time-consuming and cumbersome both for patients and medical personnel. There is an unmet need for easier to conduct, shorter, and safer diagnostic tests. We and other groups have previously demonstrated that acute administration of glucagon...

Introduction: Increased insulin-like growth factor 1 (IGF-1) levels in patients with acromegaly are associated with clinical and radiological osteoarthritis (OA). We aimed to elucidate whether serum IGF-1 levels differ in patients with primary OA as compared to healthy controls and whether genetic variants known to affect serum IGF-1 levels are also associated with primary OA.Methods: Patients from the GARP study with familial generalized OA (n=...

Context: Lipodystrophy is characterized by subcutaneous fat loss, fat maldistribution, and metabolic syndrome. We present a novel phenotype of partial acquired lipodystrophy, possibly associated with childhood chemotherapy.Case reports: Two adult female patients that had been exposed to intensive cytostatic treatment in childhood for leukemia and aplastic anemia, respectively, were referred for therapy resistant diabetes. Both patients had distinct parti...

Objective: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder characterised by menstrual dysfunction, infertility, presence of polycystic ovaries and biochemical and clinical hyperandrogenism affecting up to 4–18% women of reproductive age. Vitamin D is thought to influence the development of PCOS through gene transcription and hormonal modulation of insulin metabolism and fertility regulation. The aim of this prospective case–control study was to...

Introduction: Phaeochromocytomas often induce hyperglycaemia. Few cases are reported with hypoglycaemic fits. The mechanism is unknown. Our findings may indicate a mechanism.The patient: A 37 year old female had a phaeochromocytoma, with typical characteristics: attacks of headache, nausea and sweating. High blood pressures, up to 237/134. Electrocardiogram indicated ischemia, normal coronary arteries on dynamic CT, normal Echo-Doppler heart examination....

It is well known that adrenal masses, particularly adenomas are frequently related to metabolic syndrome and insulin resistance. However, there are no reported data about the differences between adenomas and hyperplasia.Authors examined the prevalence of symptoms of the metabolic syndrome and insulin resistance in 25 patients with adrenal incidentalomas (10 men, 15 women) of the mean age 57.9+15 years. 15 patients had adrenal adenoma determined by CT or ...
