Background: Detection of MRI-negative ACTH-producing pituitary adenomas is a challenge inthe management of patients with Cushing’s disease. There are some data on theability of pituitary adenomas to accumulate 18F-fluorodeoxyglucose during the 18F-FDG positron emission tomography and computer tomography (18F-FDG PET/CT). Aim: To study the potential of using a standardized uptake value (SUV) and a tumor &...

Background: Immigrants from the Middle East to Sweden have a twice as high prevalence of type 2 diabetes (T2D) and obesity as native-born Swedes. Both obesity and T2D have been linked to increased incidence of cancer, cardiovascular disease (CVD) and all-cause mortality (ACM); however, data on differences between ethnicities are scarce. Aims: In a population-based cohort we aimed to study the impact of Middle Eastern and European ethnicity on ACM, cancer...

Introduction: Insulin-like growth factor 1 (IGF-1) is an established serum marker for both diagnosis of growth hormone (GH) deficiency and for monitoring treatment with Somatropin, whether it is recommended for the classic GH-insufficient short stature cases or for other GH-sufficient disorders.Aim: To evaluate whether serum level of IGF-1 at diagnosis has a predictive value for the response to somatropin treatment during the 2 years of treatment in chil...

Background: If the laboratory results are not compatible with the patient’s clinical symptoms, the presence of possible test interference should be considered. Despite the excellent quality of immunoassays, it is currently estimated that they may be susceptible to several types of interference that may lead to patient misdiagnosis.Case report: In our case report we present a 71-year-old woman with confirmation of macro-adrenocorticotropic hormone (m...

Introduction: Non-Hodgkin lymphoma (NHL) involving the hypothalamus and pituitary gland is rare. Central nervous system involvement by NHL may be either as a primary tumour or from systemic lymphoma. We report an interesting case of aggressive central nervous system (CNS) lymphoma presenting as pituitary macroadenoma.Case report: A 67-year-old Caucasian woman presented with sudden onset of left eye ptosis and diplopia. Examination showed left third nerve...

There are some data on the possibility of pituitary adenomas to accumulate 18F-fluorodeoxyglucose (18F-FDG) during the 18F-FDG positron emission tomography and computer tomography (18F-FDG PET/CT).Aim: To study the potential of brain 18F-fluorodeoxyglucose PET/CT for localization of MRI-negative ACTH-producing ...

Cushing’s syndrome (CS) is a relatively rare disease characterized by autonomous hypersecretion of cortisol. The incidence of CS is estimated to be equal to 2–3 cases per million inhabitants per year.The incidence of acromegaly is 3–4 patients per 1 000000 per year. The disease is caused by hypersecretion of growth hormone which is mainly caused by benign tumour of the pituitary gland. In our case report we present a 41 - year - old woman suffering from both Cus...

The Austrian Acromegaly Registry is an initiative of the Austrian Society for Endocrinology and Metabolism. This database includes 607 patients (54% females) followed in twelve centers. Mean treatment period is 10.7 years (range 0–50 years), the total number of patient-years is 6470. Here we report gender-specific differences in the presentation, therapy and biochemical control of acromegaly in patients included in this registry.Mean age at diagnosi...

The peptides acylated and unacylated ghrelin (AG and UAG) are produced predominantly in the stomach. AG is the only known circulating orexigenic hormone with obesogenic and insulin-desensitising properties. Recent evidence suggests that UAG can inhibit these activities of AG. To investigate potential inhibitory effects of UAG and AZP-531, a UAG analogue, on AG-induced appetite and obesity we used an established rat model of diet induced obesity. Animals were fed a high-fat die...

Background: Melatonin is mostly known as a circadian hormone, but it also has effects in a large number of cellular processes (cell differentiation, proliferation, apoptosis, redox balance). Although it was studied in many tumours, very little is known about his role in pharyngo-laryngeal carcinomas.Aim: To evaluate serum melatonin levels in patients with pharyngo-laryngeal malignant tumours preoperatively and after surgical excision of the malignancy.</...
