The CYP27B1 gene encodes 25-hydroxyvitamin D-1α-hydroxylase. Mutations of this gene cause vitamin D-dependent rickets type 1A (VDDR-IA, OMIM 264700), which is a rare autosomal recessive disorder. Herein we report five patients with 1α-hydroxylase deficiencies. We studied six patients from three families who diagnosed as 1α-hydroxylase deficiency clinically. All patients had hypocalcemia, hypophosphatemia, hyperphosphatasemia, elevated serum PTH, normal or high v...

Background: A one-month-old girl was referred to our unit for osteogenesis imperfecta (OI). She was the first child of non consanguineous parents. The father had no history of fracture. The mother, 28 years-old, presented with a severe OI, short adult height (140 cm), moderate scoliosis. She had more than 20 limb fractures, no vertebral fracture and bowing limbs without need of surgery. She received Bisphosphonates during 3 years until 12 years of age. Then sh...

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...

Introduction: Vitamin D-dependent rickets (VDDR) describes a group of genetic disorders characterized by early-onset rickets that develops due to insufficient concentration of active forms of vitamin-D or unresponsiveness to active vitamin D. The aim of this study was to share the clinical features and long-term outcome of cases followed up in our center with the diagnosis of either VDDR-Type-1 and VDDR-Type-2.Method: Pr...

Objective: The aim of this study was to analyse bone mineral status in children with epilepsy, on antiepileptic drugs (AEDs) regimen, using serum calcium, 25 (OH) vitamin D and Bone alkaline phosphatase (BALP) and compare these with age and sex matched controls.Patients and Methods: This was a case - control study, conducted at University of Port Harcourt Teaching Hospital, from September 1 2018 to May 31 2019, with 200 ...

Background: Attention Deficit Hyperactivity Disorder (ADHD) is the most prevalent chronic behavioral disorder among children. No definite pathology is yet defined for this disorder and findings are in favor of multifactorial hypothesis.Aims: This study was performed with the aim of determining the association between vitamin D serum levels and ADHD among 6-14 year-old children referring to Imam Khomeini Hospital Complex during 2014–2015 in Tehran, I...

Background: Newborn screening for congenital adrenal hyperplasia (CAH) is based on the determination of 17-hydroxyprogesterone (17OHP) on blood and its need is confirmed by the most recent guidelines on the subject. In Italy this screening is not mandatory, and its application is on a regional basis. Among its disadvantages, it is well known the high frequency of false-positives, in particular in premature babies and those born small for gestational age. Howev...

Craniopharyngioma is a rare, embryonic malformation of the sellar/parasellar region with low histological grade. In childhood-onset craniopharyngioma (CoCR), endocrine dysfunctions, severe obesity and metabolic syndrome (MetS), neurological impairment and reduced quality of life have been described as consequences of both localization and treatment. To characterize a population with CoCR and to correlate endocrine/metabolic sequelae with different surgery approach we performed...

Background: Increasing incidence of pediatric obesity has been observed worldwide. Metabolic syndrome, characterized by visceral obesity, dyslipidemia, hypertension and impaired glucose metabolism, is associated with obesity.Objective and hypotheses: To evaluate early ocular signs of hypertension by retinography in a cohort of overweight (BMI>85th)/obese (BMI>95th) children, in order to define the prevalence of retinal alterations and characteriz...

Background: CS is characterized by excess glucocorticoid excess, either endogenous or exogenous. In children younger than 7 years, the adrenal origin is the most common cause. From this age until adulthood predominates Cushing’s disease (central cause). We can divide CS in ACTH-dependent and independent according to laboratory findings. When ACTH-independent, etiologies are related to benign or malignant diseases of the adrenal or McCune Albright syndrome.<p class="ab...
