Cortisol rise during pregnancy is connected with fetal maturation. Together with the increase of insulin resistance it might have a role in allocation of nutrients between mother and fetus. Cortisol and insulin secretion during pregnancy seems to be induced by fluctuations in BMR. Here, we try to identify relationship between BMR and secretion of cortisol and insulin during pregnancy.In 25 healthy women (age range 20–39 years; mean±S.D.<...

A 34 year-old female patient was admitted to the hospital because of a large nodule in the left thyroid lobe and elevated calcitonine level. A large encapsulated tumor was found and total thyroidectomy with left neck dissection was performed. Pathohistology revealed medullary and papillary carcinoma separate from each other in tumor tissue but mixed in regional lymph nodes. Papillary component was dominant in thyroid tissue but not in lymph nodes. Both calcitonine and thyroglo...

Neuroendocrine tumours (NETs) have a unique ability to produce and secrete a variety of biogen amines and peptide hormones. They arise from multipotential stem cells, which differentiate during tumorigenesis into specific cell lines. Some of these tumours are functional, producing characteristic clinical syndromes. We present a female patient incidentally discovered to have diffuse liver metastases of neuroendocrine tumour of unknown primary origin. She was free of symptoms at...

We have previously shown impaired neuroendocrine responses to ghrelin in patients with AN. The aim of this study was to investigate the metabolic responses during infusions of active ghrelin in severly malnourished patients with AN and compare them with responses of amenorrhoic AN patients who recovered body weight (PRAN) and constitutionally thin subjects (CTS) with regular menstrual cycles and without history of eating disorder and recent weight loss. Study was approved by t...

Ghrelin is gastric peptide with appetite stimulating and growth hormone (GH) releasing properties. Circulating ghrelin levels decrease after nutrient ingestion, oral and iv glucose challenge. It has been hypothesized that vagal system may have a major role in initiating this decrease.The aim of this study was to investigate circulating ghrelin levels during oral glucose challenge in gastrectomized (GASTRX)- vagotomized patients. The study was approved by...

Criteria to define biochemical remission of acromegaly following surgery have changed over the years, but still the controversy about current consensus exists. We assessed seventy newly diagnosed patients with acromegaly (43 females and 27 males, mean age 46.9±1.4 years, range 17–66 yrs) 8 weeks after transsphenoidal pituitary adenomectomy done by the same neursurgeon. Current consensus criteria were used to define postoperative remission: glucose-suppressed (nadir) ...

Normal linear growth in children is highly complex process, regulated by interaction of genetic, environmental and hormonal factors.We present four growth hormone deficient patients which despite severe growth hormone deficiency according to the provocative tests (ITT or GHRH+GHRP-6) and decreased IGF I level grew normally. This study was approved by Ethical Committee of University Clinical Center Belgrade. Three of our patients had idiopathic multiple p...

Hemorrhagic fever with renal syndrome (HFRS) is an acute viral disease caused by Hantavirus. One of the rare complications of this disease is hypopituitarism (only sporadically reported) due to hemorrhage, necrosis and atrophy of anterior pituitary lobe. The aim of the study was to investigate the anterior pituitary function in patients who recovered from HFRS.We evaluated 31 patients (29 male and 2 female), aged 38.7±2.2 years, with BMI 25.7±0...

Posttreatment assessment of the disease activity and definition of cure of acromegaly, by measuring GH secretion, remains problematic. Furthermore, with our efforts to achieve tight biochemical control of the disease it is foreseeable that a proportion of patients may be rendered GH deficient (GHD). The aim of our study was to evaluate residual GH secretion in cured patients with acromegaly. The study was approved by the Hospital Ethical Committee and after informed consent, b...

Acromegaly is associated with cardiovascular diseases. Accelerated atherosclerosis may have important role in that. The aim of this study was to examine the presence of dyslipidemia, glucose control imapairment, inflamation and hypertension as risk factors for the development of atherosclerosis in acromegalic patients.Study group included 28 patients with acromegaly without lesions of thyroid, adrenal and gonadal axis. The examination was performed befor...
