Inherited thyroxine binding globulin (TBG) disorder can be identified incidentally or through neonatal screening test. TBG excess is characterized by high levels of thyroxine (T4) but normal level of free T4 (fT4), while TBG deficiency presents with low T4 levels and normal fT4 levels. TBG excess is caused by TBG gene duplication or triplication. A 27 day old newborn was brought to the hospital because of hyperthyroxinemia that was identified through neonatal screenin...

Background: Cyclic treatment with bisphosphonates (BP) is now considered a ‘standard care’ for children with osteogenesis imperfecta (OI). Vitamin D is a necessary nutrient for bone health for all children but especially for those with OI. In the literature few studies have considered the relationship between bone mineral density, vitamin D and pubertal stage in children treated with BP for OI.Objective and hypotheses: The purpose of this study...

Background: Vitamin D deficiency/insufficiency seems to occur frequently in children and teenagers but it is a matter of debate if limits (<20 ng/ml; <30 ng/ml) are correct. Besides its effect in bone metabolism Vit-D is also supposed to have a positive influence in diabetes mellitus 1 (DM1).Objective and hypotheses: To study 25OHD and iPTH values in a group of patients (pts) (n=57) with DM1 without Vit-D substitution (2011), with 1000 I...

Background: Basal levels of androgens, in particular 17-OHprogesterone (17OHP), are widely debated as predictors of non-classical congenital adrenal hyperplasia (NCCAH) among patients with precocious pubarche (PP). So many authors suggested the execution of ACTH stimulation test in all children with PP. The aim of our study was to identify clinical and biochemical predictors of NCCAH in children with PP.Methods: We conducted a prospective study of 92 pat...

Background: There are some studies about vitamin D level and type 1 or type 2 diabetes mellitus (DM). Its effect on metabolic control of patients with type 1 DM is the subject of this study.Patients and Method: In 339 patients with type 1 DM, 192 cases (99 males, 93 females) randomly enrolled in the study. The age of males was 9 ± 4.4 yr and age of females was 8.3±4.3 yr. Their HbA1C and 25(OH) D3 were measured by HPLC method. ...

Introduction: 17α-hydroxylase deficiency (17OHD) is a rare form of congenital adrenal insufficiency characterized with decreased cortisol and sex steroid biosynthesis, overproduction of ACTH, and increased mineralocorticoids. The overproduction of corticosterone hinders the symptoms of glucocorticoid deficiency and causes sodium retention, hypertension, and hypokalemia in severe cases. Affected 46,XX and 46,XY individuals are phenotypically female in the...

Background: The gastrointestinal (GI) tract plays a central role in maintaining energy balance and body weight regulation. These functions are mediated by the secretion of gut hormones, including ghrelin, cholecystokinin (CCK), peptide YY(PYY), oxyntomodulin (OXM) and many other hormones. Some of them are orexigenic hormones that promote food intake, while others act as satiety signals and enhance insulin secretion from the pancreatic beta cells. Current evide...

Background: Neonatal hyperthyroidism is almost always transient and related to the passage of maternal thyroid stimulating immunoglobulins (TSI). Positive TSI levels in a neonate is often diagnostic of neonatal Graves disease. The manifestation of symptoms has not been well characterized in premature infants.Clinical Case: A female infant was delivered at 27×4/7 weeks gestational age, with a birth weight of 827 g. Her mother was diagnosed with Grave...

Background: rhGH therapy may improve linear growth in children with inflammatory bowel disease (IBD). Poor bone health and abnormal body composition are recognised complications in paediatric IBD.Objective and hypotheses: To investigate the effects of rhGH on bone health and body composition.Method: Sub-analysis of 13 children with IBD (12CD; 1UC) in a randomized controlled trial. Either rhGH (0.067 mg/kg per day) as daily s.c. inj...

Background: Preterm newborns due to their immaturity, a higher incidence of mortality and increased susceptibility to iodine, are at risk of decreased thyroid function. Low levels of thyroid hormones during a critical period for the development of the central nervous system may negatively affect their psychomotor development. Screening for congenital hypothyroidism with capillary TSH is invalid for preterm babies and would require an specific thyroid function control.<p cl...
