The prevalence of adrenal incidentaloma (AI) on computed tomography (CT) in the general population has been reported to be as high as 4.2%. However, many of the previous studies in this field utilised a prospective approach with analysis of CT scans performed by one or more radiologists with a specialist interest in adrenal tumours and a specific focus on identifying the presence of an adrenal mass...
Graves’ disease (GD) is a common autoimmune disorder with a genetic predisposition. The cytokine interleukin-10 (IL-10) has a central role in mediating inflammation, which may affect the outcome of the patients with GD. To elucidate the impact of IL-10 gene polymorphisms, we performed a two-stage case–control association study of five single-nucleotide polymorphisms (SNPs) within the IL-10 gene as...
Administration of radioiodine (I131) is currently exploited for both diagnostic and therapeutic treatment of thyroid cancer. Few data are available on the sodium/iodide symporter (NIS) expression in human testis, a particular important prerequisite to predict radioiodine accumulation in the gonads of males with thyroid cancer exposed to such a treatment. In this study, we analyzed the expression of...
While oestrogen is recognized to play a key role in regulating growth, particularly in relation to epiphyseal fusion, the mechanisms that mediate its effects are still unclear. We utilized an in vitro model of chondrogenesis, the RCJ3.1C5.18 cell line, to explore the effect of oestrogen on this process. We demonstrated the presence of oestrogen receptors (ER) α and β in these cells, with increased...
The objective of the present study was to examine several dimensions of quality of life (QoL) and fatigue in patients with adrenal incidentaloma. This was a case–control study designed to analyze patient outcomes using three validated generic QoL questionnaires, EQ-5D, SF-36, and MFI-20, the results of which were compared to those obtained for age- and sex-matched controls. The study population comprised...
Acromegaly is frequently complicated by fragility vertebral fractures and diabetes mellitus. Since type 2 diabetes mellitus is a cause of secondary osteoporosis in the general population, in this cross-sectional study we aimed at investigating the association between diabetes mellitus and vertebral fractures in males with acromegaly. Fifty-seven patients (median age 47 years, range: 24–85) with active...
Wolfram syndrome (WS), also known as DIDMOAD (Diabetes Insipidus, Diabetes Mellitus, Optic Atrophy and Deafness), is a neurodegenerative disease with autosomal recessive inheritance with incomplete penetrance. DIDMOAD is a very rare disease with an estimated prevalence of 1 in 770,000 and it is believed to occur in 1 of 150 patients with juvenile-onset insulin-dependent diabetes mellitus. Additionally,...
This study is to prospectively investigate the association between serum uric acid and the incidence of type 2 diabetes in middle-aged and elderly Chinese. This study consisted of 924 non-diabetic adults aged 40 years or older at baseline. Subjects who received antidiabetic therapies and those who responded positively to the 75-g oral glucose tolerance test according to the 1999 World Health Organization...
Apelin is a peptide known as the ligand of the G-protein-coupled receptor APJ. Several active apelin forms exist such as apelin-36, apelin-17, apelin-13, and the pyroglutamated form of apelin-13. Apelin and APJ are expressed in the central nervous system, particularly in the hypothalamus and in many peripheral tissues. Apelin has been shown to be involved in the regulation of cardiovascular and fluid...
Preimplantation factor (PIF) is a novel embryo-secreted immunomodulatory peptide. Its synthetic analog (sPIF) modulates maternal immunity without suppression. There is an urgent need to develop agents that could prevent the development of type 1 diabetes mellitus (TIDM). Herein, we examine sPIF’s preventive effect on TIDM development by using acute adoptive-transfer (ATDM) and spontaneously developing...
Our objective is to outline the utility of adrenal venous sampling (AVS) with measurements of metanephrine to normetanephrine ratios for diagnostic localization of phaeochromocytoma in a patient with normal plasma levels of catecholamines. A 53-year-old-woman was referred for evaluation of recurrent pheochromocytoma following a right adrenalectomy 14 years earlier. Diagnosis of recurrent disease was...
Vitamin D-dependent rickets type 1 (VDDR-I) is caused by mutation in CYP27B1. The glycine residue at codon 102 is not conserved between human (G102) and rodent (S102). G102E mutation results in 80% reduction in its enzymatic activity but PolyPhen predicts benign change. It is not known whether G102S has any damaging effect on 1α-hydroxylase activity. We investigated the effect of CYP27B1G102S on...
Subclinical hypothyroidism is associated with an increased risk of atherosclerosis. The aim of this study was to investigate the concentration of plasma soluble intercellular adhesion molecule-1 and adiponectin in relation to insulin sensitivity in patients with subclinical hypothyroidism and to estimate if l-thyroxine treatment had an influence on these parameters. 13 women with subclinical hypothyroidism...
It remains elusive what factors induce growth without growth hormone (GWGH) in children after neurosurgery of brain tumors. Growth velocity and endocrinological data were compared between the patients with and without GWGH. We experienced three patients with GWGH (median, 12 years; 2 germinoma and 1 craniopharyngioma; three females; group 1) and 11 patients without (12 years; 8 craniopharyngioma,...
RecQ-mediated genome instability 1 (RMI1) has been identified as a novel energy homeostasis-related molecule. While recent studies have suggested that change in RMI1 expression levels in adipose tissue may affect the body’s energy balance, no reports have identified the mechanism behind this expression regulation. In the present study, we found that RMI1 expression increased on differentiation of...
Hereditary vitamin D-resistant rickets (HVDRR), an autosomal recessive disorder caused by inactivating mutations in the vitamin D receptor (VDR) gene. We identified two affected children from the same family, one at the age of 10 years and 9 months and the other at 9 months old. Mutation analysis by PCR-sequencing the entire coding region of the VDR gene revealed a homozygous C to T transition in...
LHRH release from hypothalamus is influenced by the neurotransmitter glutamate that acts, among others, on NMDA receptors present in LHRH neurons. On the other hand, the neurosteroid allopregnanolone can modulate the activity of specific neurotransmitter receptors and affect neurotransmitter release. We examined the role of allopregnanolone on in vitro LHRH and glutamate release from mediobasal hypothalamus...
