Sex chromosome disorders, including sex chromosome mosaicism, result in a large clinical spectrum. There is scarce information about the histological pattern of these gonads.Aim: to characterize the histology and cell markers pattern in gonads of patients with chromosomal mosaicism.Gonadal biopsies from thirteen patients with chromosomal mosaicism, including chromosome Y were studied. Six were rearing as male and s...

Introduction: Human newborn(NWB) respiratory derangements may be concomitant to oral/enteral caloric intake (KOE) insufficiency. We evidenced a possible involvement of axillary temperature(TEMP) in relationships between preterm birth (PTB) and blood serum Insulin-like Growth Factor-I(IG1) in NWBs. Here we evaluate the TEMP-independent role of birth gestational age(GA) and KOE in relations of O2 supplementation in respiratory gases(O2S) to IG1 in the not-life-t...

Background: The pathophysiological mechanism of skeletal fragility in Duchenne Muscular Dystrophy (DMD) is unclear.Objective: To compare trabecular bone microarchitecture, cortical geometry, muscle area and fat fraction (FF) at distal femur and vertebral bone marrow adiposity (BMA) between DMD and controls.Method: Bone-muscle and muscle FF were assessed using 3T MRI and Dixon technique. BMA was assessed using 1H-MRS. Results expres...

The contiguous gene deletion syndrome, CAH-X, was reported in an 8.5% of Congenital Adrenal Hyperplasia (CAH) patients with a TNXA/TNXB chimera. This results in deletions of CYP21A2 gene, encoding 21-hydroxylase necessary for cortisol biosynthesis, and TNXB, encoding the extracellular matrix glycoprotein tenascin-X (TNX). There are three TNXA/TNXB chimeras (CH1, CH2, CH3) that differ in the junction site, resulting in TNXB haploinsu...

Introduction: Preterm delivery may comport blood serum Insulin-like Growth Factor-I (IG1) decrements and lower body temperature during the first days of postnatal life of the human newborn (NWB). We evaluated the role of preterm delivery in associations between axillary temperature (TEMP) and IG1 in NWBs without life-threatening disease.Methods: NWBs with any among total parenteral nutrition, blood transfusion, therapeutic hypothermia, life-threatening d...

Introduction: Body temperature determinants include head-brain thermal homeostatic mechanisms and, in the human newborn (NWB), birth gestational age (GA). Estimated birth brain weight (BRW) ratio to birth body weight (BW)(BBR) resulted associated with GA and blood serum Insulin-like Growth Factor (IGF)-II(IG2) ratio to blood serum IGF Binding Protein-3 (IB3)(IG2 through chronologically-corresponding IB3, IG2/IB3R) in our previous NWB observations. Here we evaluate BRW, BW, BBR...

Aggrecan (ACAN) is the major proteoglycan in the articular cartilage, critical for the structure and function of growth plate cartilage.Case Report: 11-year-old (y) boy admitted at 1.8 y of chronological age (CA), due to poor growth rate Height (H): 76 cm (−2.75 SDS). Initial physical examination: mild dysmorphic features and prepubertal external genitalia (two scrotal testes, 1 cc volume each). Neurologic maturation was normal. Initial bo...

Background: Published studies of radiologically confirmed fractures in sufficiently large cohorts of boys with Duchenne Muscular Dystrophy (DMD) are limited.Objective: To determine the incidence of fractures in a contemporary cohort of 91 boys with DMD managed in all Scottish centres.Method: Radiologically confirmed fractures were classified into vertebral fracture (VF) and non-VF in a retrospective audit of all boys currently mana...

Background: There is a direct relation between C-reactive protein and leukocyte count as indicators of inflammation. The neutrophil lymphocyte ratio (NLR) is the balance between both cells and is considered a marker of low-grade inflammation and an indicator of high risk of cardiovascular events. An elevated NLR is related with type 2 diabetes (T2D), however, even when in type 1 diabetes (T1D) there is an underlying inflammatory process, an elevation of circulating neutrophils...

Background: Aromatase deficiency is a rare autosomal recessive disorder produced by CYP19 gene mutations. 46XX affected patients presented with ambiguous genitalia leading to early identification. Most 46XY affected patients presented normal external genitalia and the condition often remains undiagnosed until late puberty. Information on pubertal development in affected boys is scarce since to the present date only two patients, younger than 4 years of age, without lo...
