Background: Phosphoglucomutase 1 (PGM-1) deficiency is a congenital disorder of glycosylation caused by an impairment of glucose-1-phosphate and glucose-6-phosphate interconversion.The clinical phenotype of PGM1 deficiency is variable and includes several endocrine manifestations such as recurrent hypoglycemia and short stature, which may be associated with the decreased levels of growth hormone (GH), insulin like growth factor-1 (IGF1) ...

Introduction: Tuberous sclerosis complex (TSC) is an autosomal dominant condition caused by a loss-of-function mutation in tumor suppressor genes TSC1/TSC2 which are involved in the inhibition of mTOR signaling implicated in cell proliferation. Major clinical features includes cardiac rhabdomyomas, renal cysts, epilepsy associated to cerebral dysplasia evidenced by cortical tubers and skin manifestation as: angiofibromas, fibrous plaques and the Shagreen patch...

Background/Aim: Parents wanting to predict adult height (AH) often resort to the old practice of doubling a boy’s height at age 2 years or a girl’s height at 18 months. We coined this the ’Grandma prediction’ (GMP1). It provides predictions with mean absolute error (MAE) 5.9 and 5.2, standard deviations of residuals (sdRES) 4.1 and 3.6, and Pearson correlation r=0.68 and 0.67 for boys and girls, respectively. The recent sophist...

Background/Aim: The trade-off theory claims that a resource (calorie) stored in adipose tissue cannot be used for longitudinal growth, and a calorie used for growth will not be stored as fat.Methods: Out of 2339 children with longitudinal heights and weights (birth to adulthood) from the GrowUp1990 Gothenburg cohort, 1993 (996 girls) were analyzed. For everyone we calculated Energy Trade-Off Score: ETOS = at early adulth...

Introduction: Deficiency of 17β-hydroxysteroid dehydrogenase 3 (17β-HSD3) enzyme encoded by HSD17B3 is a rare cause of disorders of sex development (DSD). The phenotype associated with 17β-HSD3 deficiency in 46, XY individuals is variable, ranging from predominantly male external genitalia with micropenis and hypospadias to completely female external genitalia. The diagnosis and management of this enzymatic defect is very challenging.<p class="abste...

Background: Premature adrenarche (PA) has been considered a benign condition. Recently, associations with increase androgen levels and PCOS have arisen.Objective: To determine whether PA in children at pubertal onset (TII) determines a different timing of pubertal events and a different pattern of ovarian and adrenal hormones.Methods: A total of 583 girls from the longitudinal cohort (Growth and Obesity Cohort Study, born 2002) wer...

Background: Premature adrenarche (PA) has been considered a benign condition. Recently, associations with an increased metabolic risk have arisen. This risk may depend on ethnic background and infancy weight gain, which could be different by gender.Objective and hypotheses: To determine whether PA in children at pubertal onset (TII) determines a higher metabolic profile.Methods: 1190 children (49.9% female) from the longitudinal co...

Context: Physiological growth hormone is secreted during the slow-wave sleep. Traditionally, growth hormone (GH) therapy is given in daily GH injections before sleep. This schedule better imitates the physiological diurnal variation of GH secretion and action. Late-night daily injections have been claimed to be associated with sleep disturbances and insomnia, yet there is no hard evidence supporting this contention. Morning and evening GH injections produce co...

Background: Childhood craniopharyngiomas are known to be associated with an increased risk of excessive weight gain and hypothalamic obesity. Atypical clinical manifestations include the development of a diencephalic syndrome (DS) with a failure to thrive or weight loss.Objective and hypotheses: In a retrospective study we analyzed 21 of 485 childhood craniopharyngioma patients (4.3%) who presented with a low weight (<−2 BMI SDS) at time of dia...

Introduction: The aim of the project “DSDCare” is to implement standardized care for people with DSD following national and international guidelines and to evaluate structural, process and outcome quality of care at 10 specialized centres in Germany from May 2020 till June 2023. Transition from paediatric to adult care is a crucial phase in chronic and rare conditions. In DSD, “loss to follow-up” is usually not associated with acute com...
