We report on a 17-year-old patient with hypoparathyroidism which was noticed during the diagnosis of a first renal colic a year and a half ago. At that time, a prevesical ureter stone on the right could be depicted sonographically, which disappeared spontaneously. Initially calcium levels in serum and urine were reported to be normal. However, a slight hypercalcemia and hypercalciuria as well as high normal vitamin D levels without vitamin D substitution were detected intermit...

Background: Pseudohypoparathyroidism is a rare congenital disorder presenting with variable symptoms and features. Since 2016 a new international nomenclature subclassifies the different forms of pseudohypoparathyreoidism as inactivating PTH/PTHrP signalling disorders (iPPSD). Pseudohypoparathyreoidism 1A (iPPSD2) and 1B (iPPSD3) are mainly characterized by resistance of parathyroid hormone (PTH) with high serum PTH levels and thyrotropin (TSH) resistance. In ...

People born with a variation in sex characteristics (VSC) face the challenge of having atypically sexed bodies. This quantitative study recruited 10 young adults with a VSC (14 to 24 years); 18 parents of children with a VSC; and 22 health professionals working in the VSC field. Interviews were semi structured, digitally recorded and transcribed. Using thematic analysis, we identified key themes regarding participants' experiences of health care decision-making. This study...

Background: Pseudohypoparathyroidism (Albright hereditary osteodystrophy (AHO)) is a rare congenital disorder mainly affecting bone and thyroid metabolism as a result of resistance of parathyroid hormone (PTH) and thyrotropin (TSH), gonadotropins, growth hormone-releasing hormone (GHRH) and calcitonin in the target tissues. According to the consensus statement "Diagnosis and management of pseudohypoparathyroidism and related disorders" published in 201...

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: Mutations in the side chain cleavage enzyme, (CYP11A1) cause congenital adrenal insufficiency, with complete or partial 46XY sex reversal. The disorder manifests with adrenal and gonadal insufficiencies along with derangements of the renin/angiotensin system.Objective and hypotheses: To obtain a genetic diagnosis in six patients with adrenal insufficiency of unknown aetiology. Patients 1 and 2 are sisters with ACTH resistance, having...

Background: Adrenal insufficiency is a rare cause of neonatal cholestasis, which is reversible with prompt glucocorticoid administration.Case presentation: A 2-month old baby boy was referred to the paediatric endocrine department for evaluation of intermittent hypoglycaemia associated with metabolic acidosis, hyponatraemia and hyperkalaemia. The infant was second born to second-degree consanguineous parents whose first...

Introduction: Childhood obesity shows increasing numbers worldwide and presents as a global health issue due to multiple metabolic comorbidities. About 1 % of adolescents with obesity develop type 2 diabetes (T2D), however little is known about the genetic and pathophysiological background in young age. Genome-wide association studies in adults revealed genes with increased diabetes risk, most of them regulating insulin secretion. The objective of this study w...

Background: X-linked hypophosphatemia (XLH) is a rare, progressive, genetic phosphate wasting disorder leading to rickets, lower limb deformities as well as short and disproportionate stature. The condition is inherited in the majority, however spontaneous mutations are reported in ≈30% of cases. Its rarity, coupled with its diverse clinical manifestations, may lead to delayed diagnosis and subsequently delayed treatment initiation. The objective of this an...

Background: The typical biochemical phenotype related to obesity, that is high serum thyrotropin (TSH) within normal range, low/normal free thyroxine (FT4) and increased free triiodothyronine (FT3) levels, can be interpreted as a resistance to thyroid hormones. It is unclear the role played by thyroid hormones in the pathogenesis of metabolic derangement associated with obesity.Aim: To investigate the association between...
