McCune–Albright syndrome (MAS) is a rare disease. It is characterized by a combination of polyostotic fibrous dysplasia, autonomous overproduction of hormones and skin hyperpigmentation.Thirty-year-old patient with significant bone deformities and the history of multiple fractures of long bones despite treatment presented with multinodular goiter with long standing hyperthyroidism. During thyroidectomy in 2009 two enlarged nodules suspected for bein...

Background: Body composition of females with polycystic ovary syndrome (PCOS) varies considerably. The literature lacks of skeleton size description in women with PCOS. Objective of the present study was to investigate skeleton robustness in PCOS women.Material and methods: Hundred and one PCOS women (by androgen excess society criteria, mean age 26.85±3.91 years) and 81 healthy control women (mean age 27.95±3.65 years) were investigated in Vil...

Introduction: Pheochromocytoma is an uncommon tumor. Non-classical forms can make diagnosis difficult and delay correct management strategies.Case report: A 20-years old caucasian male presented to the emergency room with unproductive cough, fever and tiredness for 7 days. He was eupneic, afebrile, BP 176/115 mmHg, 104 bpm with inspiratory crepitations in the left lung base. Leucocyte–14.1×109/l (N 70%); platelets – 659×10<...

Background: Clinical manifestations of hyperthyroidism resemble those of hyperadrenergic state. Previous studies of linear analysis of heart rate variability (HRV) revealed cardiac autonomic dysfunctions in hyperthyroidism. In recent years, increasing attention is being directed to the nonlinear analysis of HRV to gain insight into neural modulation of heart rate dynamics. Based on the chaos and fractal theory, an attractor in phase space can characterize the dynamics of a cha...

The binding characteristics of maternal serum human chorionic gonadotrophin (hCG) to immobilised lectins, specifically Concanavalin A (Con A), Lens culinaris agglutinin (LCA) and Wheat germ agglutinin (WGA), have been shown be compatible with the proposed glycosyl structures of hCG as inferred from other analytical methods. We have shown that serum hCG from groups of pregnant women with or without type 1 diabetes show identical affinity for Con A and LCA, but serum hCG from th...

Increasing energy intakes of sows may decrease the severity of changes in body condition occurring throughout the reproductive cycle and lead to improved efficiency of energy utilisation. The study aimed to examine the effects of feeding extra energy during late pregnancy on body fat deposition, reproductive performance and plasma insulin concentration.Twenty-four multiparous sows were randomly allocated to one of three dietary treatments. From day 85 of...

A 44 year old man was referred with a 3-week history of progressive visual failure without headaches. He had bitemporal hemianopia but no evidence of endocrine dysfunction. MR scanning revealed a large pituitary macroadenoma with evidence of intralesional haemorrhage and compression of the optic chiasm. Endocrine testing revealed no evidence of a hormone excess syndrome or hypopituitarism. Transphenoidal hypophysectomy was performed urgently in May 2000 and his vision improved...

Perinatal nutrition has marked effects on both the health and development of the newborn animal, especially in the case of the intra-uterine growth restricted (IUGR) foetus. IGF-1 and leptin play important roles in the regulation of growth and energy metabolism. The study aimed to examine whether prenatal nutrition influences the growth performance and endocrine profile of IUGR pigs. From day 85 of gestation, pregnant sows were allocated to the standard diet (S: n=4) or the S ...

Annexin I (ANXA1), a Ca2+- and phospholipid-binding protein is an important mediator of glucocorticoid (GC) action in the host defence and neuroendocrine systems. In the anterior pituitary ANXA1 is highly expressed by the folliculo-stellate (FS) cells (1). We have shown that GCs cause the externalization of annexin I in a FS cell line (murine TtT/GF) despite the fact that ANXA1 lacks a signal sequence and is not packaged in secretory granules. In bacteria and yeast ...

Background: Klinefelter syndrome (KS) is the commonest sex chromosomal disorder. Characteristic features include male phenotype with hypogonadism and progressive testicular failure, gynaecomastia and learning difficulties. The association between mediastinal germ cell tumours (GCT-M) and KS is well established, with KS occurring in 20% of GCT-M patients and the reported incidence of GCT-M in KS being 1.5 per 1000 (Nichols, 1991). Genital anomalies are also known to be rarely o...
