BACKGROUND Magnesium levels may be decreased in patients with type 1 diabetes mellitus (T1DM), influencing disease control. Relevant studies concern mainly adults and there are few data from the pediatric population. The aim of the present study was to evaluate magnesium levels and examine their possible association with glycemic control in youths with(More)
Obesity in childhood increases the risk for early adult cardiovascular disease. However, the underlying mechanism is not fully known. The aims of this study were to measure levels of prothrombotic factors and examine their possible association with obesity and insulin resistance in obese children and adolescents. A total of 313 obese children and(More)
Vaginal bleeding and/or discharge in young girls may result from infection, urological problems, endocrine causes, bleeding disorders, dermatological conditions, trauma, sexual abuse, masses or foreign bodies. We report a case of excessive vaginal bleeding caused by a foreign body in a prepubertal girl with emphasis on the diagnostic challenges and pitfalls(More)
OBJECTIVE This study aimed to investigate any possible interactions between hormonal regulators of weight gain and markers of subclinical inflammation in childhood obesity. Forty-one obese prepubertal children and 41 age- and gender-matched lean controls were included. Children were classified as obese or non-obese according to international age- and(More)
OBJECTIVE To estimate markers of prothrombotic state and endothelial dysfunction in youths with type 1 diabetes mellitus (T1DM) and investigate possible associations with anthropometric/demographic data, glycaemic control and lipid profile. METHODS In a cross-sectional design, we recruited 155 youths with T1DM and determined levels of plasminogen(More)
BACKGROUND QT-wave abnormalities have been detected in type 1 diabetes mellitus (T1DM). Prolongation of the heart rate corrected QT interval (QTc) has been associated with cardiovascular mortality. We evaluated how often QT/QTc abnormalities are present in youth with T1DM and if they are associated with disease parameters. METHODS Sixty-two T1DM(More)
YKL-40 (chitinase 3-like protein 1) is a newly recognized protein that is secreted by activated macrophages and neutrophils and expressed in a broad spectrum of inflammatory conditions and cancers. It has also been associated with endothelial dysfunction and diabetes in adults. Its role in childhood obesity has not been evaluated yet. Our aim was to(More)
Hajdu-Cheney syndrome (HCS) is a rare disorder principally characterized by acro-osteolysis, distinctive craniofacial and skull changes, dental anomalies and short stature. A common finding in HCS patients is secondary osteoporosis that progresses over time and contributes to various skeletal problems, especially fractures. Although autosomal dominant(More)
Acquired toxoplasmosis, although relatively common in children, is usually asymptomatic but can also be clinically manifested by a benign and self-limited infectious mononucleosis-like syndrome. Neurological complications are very rare in immunocompetent children. The authors report a 5-year-old boy who presented with cervical lymphadenopathy because of(More)
OBJECTIVE The apelinergic system has been previously described to participate in fluid homeostasis, cardiac contractility, blood pressure and neo-vascularization. The role of apelin in obesity and glucose metabolism has also lately gained interest; however, it still remains obscure. This study aimed to assess serum apelin levels in obese youngsters and to(More)
