Introduction: Various non pancreatic tumors can cause hypoglycemia. Usually they are mesenchymal, retroperitoneal tumors or fibrosarcomas. Hemangiopericytoma is a rare type of mesenchymal tumor, which mostly develops in soft tissue and originates from the Zimmermann’s pericyte (modified smooth muscle cells).Case report: Fifty-nine-years old female patient with hypoglicemia was addmited to our department. Physical finding showed mild obesity and hype...

AI are incidentally discovered adrenal masses without any prior suspicions of adrenal disease. They are most frequently hormonally inactive, with arterial hypertension (AH) as a common finding.The aim was to determine upright and supine PR and ALD levels in patients with AI, normotensive and hypertensive.Two hundred and eight patients (148 women and 60 men, mean age 55.08±11.02 years, mean BMI 27.91±4.6 kg/m2) ...

Considering that adrenal tumors are frequent in patients with congenital adrenal hyperplasia (82% in homozygote and 45% in heterozygote), Synacten test was at first introduced as marker of congenital adrenal deficiency in patient with adrenal incidentaloma. Recent studies showed normal and exaggerated cortisol response in more than 50% of patient with nonhypersecretory adrenal incidentaloma and more than 70% of patients with adrenal incidentaloma and subclinical hypercorticism...

Many studies have shown insulin resistance (IR) in majority of patients with adrenal incidentaloma. The euglycaemic hyperinsulinaemic glucose clamp technique is still considered as ‘golden standard’ for evaluation of insuline sensitivity. These methods are also complicated, labor-intensive procedure better for small research studies. Today, several surrogate indexes for insulin sensitivity were introduced such as: HOMA, QUIQI or G/IR. Some studies showed that QUIQI h...

Subclinical hyperthyroidism is a biochemical diagnosis defined with suppressed levels of TSH and normal levels of thyroid hormones. One of the main metabolic responses to thyroid hyperfunction is peripheral lipolysis and release of free fatty acids (FFA). The aim of this study was to compare levels of cholesterol, LDL, HDL and triglycerides in persons with subclinical hyperthyroidism to age and BMI matched euthyroid healthy control. We evaluated 45 persons in two groups: 1st g...

Subclinical hypothyroidism is a biochemical diagnosis defined with elevated levels of TSH and normal levels of thyroid hormones. The most common abnormality linked to this condition is hypercholesterolemia. The aim of this study was to search for MSy among the persons with subclinical hypothyroidism which was already proven to have hypercholesterolemia when compared to healthy control. MSy was identified in those with elevated triglycerides (Tgc), reduced HDL and elevated fast...

Several studies show that characteristics of metabolic syndrome are often seen in patients with adrenal incidentaloma. The aim of our study was to evaluate metabolic factors in these patients. 208 patients (148 female and 60 male, age 55.08±11.02 y’s and BMI 27.91±4.6 kg/m2) were admitted and biochemical, endocrine testing were performed. Lipid status: cholesterol 5.77±1.26 mmol/L, triglyceride 1.92±0.98 mmol/L. 113(55%) patients were hypert...

Metabolic syndrome (MS) represents a prominent risk factor for cardiovascular disease. Parameters of MS were compared between obese women and controls. I: 50 women (31.92±5.83 kg/m2; 54.4±3.64 y’s); Controls: 37 women (23.50±2.13 kg/m2; 53.92±3.95 y’s). Weight, height, waist and hips circumference, sagital abdominal diameter (SAD) and blood pressure (BP) were measured. Blood was taken at 8 am for: fasting glucose, triglycerid...

POF is a disease of unclear origin affecting women under age 40. They are at high risk of cardiovascular diseases (CVD).The objective of this study was to compare the lipid status and atherogenic indexes - total cholesterol/high density lipoprotein (TC/HDL) and low density lipoprotein/HDL (LDL/HDL) - of women with POF with healthy women of the same age and the same BMI.We evaluated 54 women in two groups. 1st group: 31 women with P...

Introduction: Secretory adrenal tumors sensitive to luteinizing hormone (LH) and/or human chorionic gonadotropin (hCG) are well documented in the literature. LH and hCG share a mutual LH/hCG receptor and a comparable physiological role.Objective: The aim of our study was to evaluate the response of adrenal steroids (cortisol, aldosterone and dehydroepiandrosterone sulphate (DHEAS)) to exogenous hCG stimulation in menopausal patients with adrenal incident...
