Introduction: Individuals with ovotesticular disorders of sexual development (OT-DSD) have both seminiferous tubules and ovarian follicles. The combination of gonads could be separated (ovary-testis), unilateral (ovotestis-ovary or ovotestis-testis), or bilateral (ovotestis-ovotestis). The last one is the rarest variant (24.5%). In 60% of cases, the karyotype is 46, XX.Case Report: 15-year-old, monochorionic-monoamniotic...

Introduction: Monogenic defects in the leptin-melanocortin pathway result in hyperphagia and severe, early-onset obesity. Knowledge of the natural history of anthropometric parameters in patients with monogenic obesity is essential for diagnosis. However, reliable data on early childhood weight and height development in affected patients are lacking. This study aimed to evaluate the history of height, weight, and BMI development in early childhood in a Europea...

Introduction: Classic congenital adrenal hyperplasia (CAH) caused by 21-hydroxylase deficiency results in impaired synthesis of gluco- and often also of mineralocorticoids. Early treatment with glucocorticoids and mineralocorticoids prevents life-threatening crises. In some centres, additional salt is prescribed in the first year. However, until now the use of salt is controversial and not proved to result in better outcome in studies.<s...

Introduction: Ghrelin binds to its receptor GHSR1A, encoded by GHSR, on somatotrophs of the pituitary. Growth hormone (GH) secretion is enhanced by ghrelin binding as well as the receptor’s constitutive activity. Results from in vitro experiments, knock-out mice, and GWAS suggest that heterozygous loss-of-function of GHSR may be associated with short stature, but observations in case studies are equivocal. We aimed to better ch...

Introduction: A derivative chromosome (der) is a structurally rearranged chromosome generated either by a chromosome rearrangement involving two or more chromosomes or by multiple chromosome aberrations within a single chromosome. Balanced segmental anomalies such as inversion or translocation can lead to derivative chromosomes with partial duplication and deletion during meiosis. Here we present two patients with hypergonadotropic hypogonadism and various acc...

Background: Biochemical ratios of precursor-to-product urinary steroid metabolites have been proposed as surrogate markers of steroidogenic enzyme activity to aid the differential diagnosis of inborn disorders of steroidogenesis. Using ratios rather than total amounts facilitates analysis of single spot urine samples, more convenient than 24-h urine collections for young children. Previous studies examining the utility of these biochemical ratios have been lim...

Background: Isolated aldosterone synthase deficiency is a rare autosomal recessive disorder caused by pathogenic variants in CYP11B2. To date, more than forty different pathogenic variants in the CYP11B2 gene causing isolated aldosterone synthase deficiency have been identified. We report on a novel pathogenic CYP11B2 variant.Case report: The second child (male) of consanguineous, healthy parents, presented shortly after...

Background: Reaching a definitive diagnosis in individuals with XY DSD is challenging and the time taken to reach a diagnosis is an important clinical benchmark that has not been sufficiently explored in this group of conditions.Objective: To evaluate the diagnostic process with a focus on the time to diagnosis in children with XY DSD reported via the e-reporting platform (e-REC) of the European Registries for Rare Endoc...

Background: Classic Congenital Adrenal Hyperplasia (CAH) needs life-long treatment of glucocorticoids. Compliance with long-term medication is still challenging, particularly in developing countries. However, there has been no prospective study about the strategy to improve compliance in CAH and its relationship with hormonal control and quality of life (QoL) in CAH, especially in underprivileged countries such as Indonesia. This study aimed to determine the r...

Background/Objective: Micro-and macrovascular changes are the cause for diabetes complications. Retinal vessel analysis is a unique method to examine microvascular changes in brain derived vessels.Subjects/Methods: Sixty-seven pediatric and adolescent type 1 diabetes patients and 58 healthy control persons underwent nonmydriatic retinal photography of both eyes. Arterioles and venules positioned in the region 0.5 to 1 diameter of the optic disc measured ...
