Introduction: In a recent 16-week Phase II study in patients with de novo, persistent or recurrent acromegaly, pasireotide effectively controlled GH and/or IGF-I levels in 56% of patients, and reduced tumor volume by >20% in 39% of patients. We present preliminary 6-month results from the ongoing extension phase of this study.Methods: This extension study enrolled patients who achieved biochemical control (GH ≤2.5 μg/l and normalize...

Objective: The aim of the study was to assess the impact of iodine supplementation (IS) on iodine intake, thyroid function and thyroid volume (Tvol) in pregnant women (PW) from iodine sufficient region of Zagreb, the capital of Croatia. The secondary aim was to asses the impact of nodular or diffuse thyroid ultrasound (US) pattern on serum thyroglobulin (Tg) measurement.Subjects and Methods: The study enrolled 91 PW taking IS (onIS) and 100 PW without IS...

Introduction: The impact of metabolic syndrome (MetS) on male infertility has been poorly studied. We recently reported that MetS is associated with hypogonadism, poor sperm morphology and testis ultrasound inhomogeneity. However, the possible associations between MetS and prostate-related symptoms and signs are still lacking.Methods: Out of 351 subjects without genetic abnormalities previously evaluated for couple infertility clinically and by scrotal u...

Goiter frequency (GF) in schoolchildren and urinary iodine concentration (UIC) in an appropriately large population sample are iodine nutrition (IN) best indicators. GF in mildly iodine deficient areas should be assessed ultrasonographically, as palpation sensitivity in such cases is low.Aim: To assess thyroid volume reference values as IN marker in population with recently introduced obligatory iodine prophylaxis (OIP).Material an...

Celiac Disease (CD) is a chronic inflammatory disorder and requires life-long treatment and follow-up. Mean platelet volume (MPV), determinant of platelet function, is an independent risk factor for cardiovascular disease (CVD). Metabolic syndrome (MS) is a multiplex risk factor that arises from insulin resistance accompanying abnormal adipose deposition and function. It is a risk factor for coronary heart disease, as well as for diabetes, fatty liver, and several cancers....

Introduction: During pregnancy, the thyroid volume (TV) increases by 20% to 35% in areas with iodine deficiency. In iodine-sufficient countries, while some studies showed an increase in TV by 10–15%, others did not observe any change in TV during pregnancy. Thyroid nodules may be present in up to 15–35% of pregnant women in areas with moderate iodine deficiency. However, in areas with iodine-sufficient, thyroid nodules were investigated in a few number of studies...

Aim: Mean platelet volume (MPV), which is a determinant of platelet function, is an independent risk factor for atherosclerosis. The aim of this study is to evaluate MPV values in gestational diabetes mellitus (GDM).Material and methods: Forty-nine women with gestational diabetes mellitus (mean age 28.2±4.7 years) and 40 healthy pregnant women (mean 26.2±4.6 years age) who came to our Out-Patient Clinic of Endocrinology were included in the stu...

Introduction: Thyroid volume (TV) depends on age, gender, anthropometry, smoking and iodine status. IGF1 plays a role on thyroid growth, as demonstrated in acromegaly and GH-deficiency. Finally, TSH is a well recognised permissive factor for thyroid tissue growth. The aim of the study is to evaluate the long-term effect of TSH-deficiency on TV in hypopituitaric patients compared with healthy volunteers.Methods: We performed a cross-sectional, controlled ...

Although MRI remains the investigation of choice for pituitary imaging, it does not reliably identify all secretory microadenomas, and cannot always discriminate residual tumour from post-surgical change following hypophysectomy. We hypothesised that i) imaging with the PET ligand 11C-methionine, which is taken up at sites of peptide/protein synthesis, would permit more reliable identification of functioning pituitary adenoma, and ii) co-registration of PET–CT ...

Objective: Morphologic and functional platelet abnormalities have been previously reported in patients with type 2 diabetes mellitus (DM) and some of these abnormalities have been linked to increased cardiovascular risk. Mean platelet volume (MPV) informs not only about platelet size, but also about its functions. Larger platelets bear more thrombotic potential. Higher MPV values have been correlated with cardiovascular events in the short and long run. Previous studies have d...
