Background: In-vivo skeletal MRI imaging remains challenging due to the extremely short MR relaxation times (<1 ms) of protons bound to water in bone. However, each MRI sequence contains properties identifiable through feature-based recognition, highlighting characteristics relating to skeletal configuration. We thus present a novel statistical method for clinical 1.5 Tesla (T) MRI in quantifying trabecular microstructure and use HRpQCT to determine its accuracy.<...

Introduction: Primary hyperparathyroidism (PHPT), often caused by a single adenoma (80%–85%) or hyperplasia or adenomas involving multiple glands, is the major cause of hypercalcemia. PHPT is common and occurs in individuals of all ages, but its prevalence is lower in young adults. Parathyroid tumors and PHPT can be caused by germline (hereditary PHPT) or somatic mutations of tumor suppressor genes (e.g., multiple endocrine neoplasia type 1 and CDC73) and...

Background and Objectives: N-terminal-pro hormone Brain Natriuretic Peptide (NT-proBNP) and hs-Troponin T (hs-TnT) are commonly used cardiac biomarkers despite lacking a deeper understanding about influencing parameters especially in the healthy pediatric population. We previously found associations between NT-proBNP and hs-TnT and a child´s age, sex, pubertal status, Body Mass Index (BMI) and serum lipid levels. Subsequently, we explored associations wi...

Case presentation: We recently started a 9-year-old girl with hypoparathyroidism due to a mutation in the PTH gene on a pump therapy with 1–34 rhPTH. She has received calcitriol and calcium since the age of 4 months. Bilateral nephrocalcinosis stage II/III was diagnosed at a young age. So far, her renal function remains normal. During the last 18 months symptomatic hypocalcemic episodes have become more frequent despite increased calcium and calcitriol doses. Continuous r...

Objective: The number of heavy newborns is increasing steadily. Often the gestational diabetes (GDM) has not been identified even though an increasing number of pregnant woman are being screened. We examined in a circumscribed area how often the pregnant women passed through an oral glucose tolerance test (oGTT) and had it been realized and interpreted according to the AWMF guidelines.Methods: In this prospective study we analyzed the OGTT results from 1...

Background: Children with more than one AID (pediatric polyautoimmunity) may have a stronger genetic component than children with a single AID. PTPN22 C1858T SNP has been associated with multiple different AIDs in adults and children.Objective and hypotheses: Evaluate the association of PTPN22 C1858T gene polymorphism with pediatric polyautoimmunity.Method: A cross-sectional study was performed in subjects with an AID of p...

Introduction: Congenital hyperinsulinaemic hypoglycaemia of infancy (CHHI) associates with mutations in known genes in approximately 60% of cases. CHHI and mutations in HNF4A gene are reported in 0.5–2.4% in large series. A case of CHHI with renal Fanconi syndrome (FS) and hepatopathy is presented.Clinical description: Male newborn, gestational age: 38 weeks, weight: 4250 g +2.7 S.D., length: 55 cm +3.29 S.D., ...

Introduction: Developing an acute onset thyroid nodule is rare in children and usually associates with infectious or neoplastic disease; when linked to hyperthyroidism, the most likely diagnosis is toxic adenoma.Clinical description: 9-year-old boy with no relevant medical history was seen at the emergency department for acute cervical pain and tumor involving the left thyroid lobe with no inflammatory signs or history of trauma. Physical examination rev...

Background: Neurofibromatosis type 1 (NF1) caused by loss of function mutation in the NF1 gene; leads to the hyperactivation of RAS and its downstream mediators and contributes to tumour formation. The main manifestations of NF1 are café au lait macule, axillary and/or inguinal freckling. Neurofibroma plexiform is specific for NF1 and identified on the face and trunk. Urogenital presentation is infrequent in the penis. Identification of this lesion is essential because it...

Background: X-linked hypophosphatemia (XLH) is a rare metabolic bone disease which is caused by inactivating mutations in Phosphate-regulating neutral endopeptidase, X-linked (PHEX). Due to dysregulation of Fibroblast growth factor 23 (FGF-23), increased systemic levels of FGF-23 lead to chronic renal phosphate wasting and to impaired activation of 25OH-Vitamin D (25OHD). As a result, patients suffer from multiple musculoskeletal symptoms such as long bone def...
