Background: Hereditary Nephrogenic Diabetes Insipidus (HNDI) is an uncommon disorder due to a resistance to anti diuretic hormone (ADH) leading to a reduced urinary concentrating ability. The X-linked form is fully expressed in hemizygous male patients, but diabetes insipidus may also present in heterozygous females where it must be distinguished from autosomal and other secondary causes.Objective and hypotheses: We report a mother and daughter with HNDI...

Background: There are published recommendations for neonates to avoid exposure to iodine. Iodine is trapped by the thyroid gland from the blood stream and used for the synthesis of thyroid hormones. Any excess is excreted almost entirely in the urine. Acute kidney injury, especially anuria places infants at risk of toxicity when exposed to iodine and paradoxical hypothyroidism can occur (Wolff–Chaikoff effect). Hypothyroidism of sufficient severity to seriously put the br...

Objective: Remission rates in young people with Graves’ hyperthyroidism are 25% or less after a 2-yr course of thionamide antithyroid drug (ATD). Immunomodulatory agents could potentially improve outcome by facilitating immune tolerance. We wanted to explore whether rituximab, a B lymphocyte depleting agent, would increase remission rates when administered with a short course of ATD.Design: This was an investigator-...

Multiple epiphyseal dysplasia (MED) is a chondrodysplasia characterised by delayed epiphyseal endochondral ossification, resulting in disproportionate short stature and early onset osteoarthritis. MED can be caused by heterozygous mutations in COMP, MATN3, COL9A1, COL9A2 and COL9A3, or bi-allelic mutations in SLC26A2. Human induced pluripotent stem cells (hiPSCs) are reprogrammed somatic cells which can differentiate to form all body tissues and have excellent potential for ti...

Context: Childhood obesity is supposed to affect growth and development in children but there is uncertainty with regard to dynamics and potential causes. We analyzed differences in age-related growth patterns of obese and normal-weight children and their association with circulating endocrine and metabolic factors.Objective/Design: In a large German childhood cohort from Leipzig including 7986 children (22793 data sets) we compared cross-sectional and l...

Introduction: Growth retardation < –2 SDS is frequently observed in children with chronic kidney disease (CKD) and is a marker of severity of CKD. Recombinant human growth hormone (rhGH) treatment has been approved since 1995 in CKD patients. The aim of this study was to describe the growth outcomes and treatment patterns in children with congenital CKD.Methods: Patients were recruited from transplantation recor...

Introduction: Anti-thyroid arthritis syndrome (AAS) is a rare complication that may occur in patients treated with anti-thyroid drugs. Presentation is variable and may include myalgia, arthralgia, skin rash, high fever, and polyarthritis. Herein, we present a girl diagnosed with AAS. Case report: A 9-year-old girl was admitted to emergency complaining of fever and arthralgia. She was the second child of non-consanguineous healthy parents. She had been d...

Introduction: Mutations of the PLS3 gene (MIM 300910), encoding plastin 3, are an extremely rare cause of osteogenesis imperfecta (OI). It has an X-linked inheritance and is characterized by early-onset osteoporosis and kyphosis, which can cause compression fractures, especially in the thoracic vertebrae. Although there are reports showing that bisphosphonates are effective in improving the bone mineral density of patients with PLS3 variants,...

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...

Introduction: Barakat syndrome, also known as HDR syndrome (OMIM 146255), is a clinically heterogeneous, rare, autosomal dominant genetic disorder, characterized by the triad of hypoparathyroidism (H), deafness (D), and renal disease (R). The phenotypic features are attributed to mutations of the GATA3 gene, which encodes a transcription factor essential for embryonic development of the parathyroid glands, auditory system, and kidneys. Here, we report...
