Impact of unilateral ovariectomy on ovarian function and pubertal development in girls with Turner syndrome

van der Coelen Sanne , Nadesapillai Sapthami , Peek Ronald , Braat Didi , Fleischer Kathrin , van der Velden Janielle

Background: A reduced reproductive lifespan is one of the most significant implications for girls with Turner syndrome (TS) and is due to an accelerated loss of ovarian insufficiency. Lately, there has been a surge in scientific research aimed at whether ovarian tissue cryopreservation (OTC) is a viable option for fertility preservation in girls with TS. This required a unilateral ovariectomy for girls with TS who may already have a poor ovarian reserve.<p...

Improving detection of rare overgrowth syndromes referred to the endocrinology ward for analysis of acromegaly

van Essen Trui , Rosenberg Anna , de Herder Wouter , Jan van der Lelij Aart , de Graaff Laura

Background: In our center for adults with rare genetic syndromes, we see adolescents and young adults with overgrowth syndromes, among others. In our 'general endocrinology' outpatient clinic, we also see patients with overgrowth, but in these cases the overgrowth is due to excess of growth hormone (GH). Our clinical impression is that the differentiation between the two is often challenging. Therefore, we believe it is important to emphasize the dif...

The narrative of a patient with leptin receptor deficiency: personalized medicine for a rare genetic obesity disorder

S. Welling Mila , Kleinendorst Lotte , M. van Haelst Mieke , L.T. van den Akker Erica

Leptin receptor deficiency is a rare genetic disorder that affects the body’s ability to regulate appetite and weight. For patients and their families, the disorder seriously disrupts daily life, however, little is published about this impact. We here report the experiences of a 10.5-year-old girl with leptin receptor deficiency and her family. The diagnosis of this rare genetic obesity had a deep impact on the life of the child and her family. It led to a better underst...

Introduction: Health related Quality of Life (QoL) outcome is used as an argument when continuation or stopping growth hormone (GH) treatment is considered in patients with idiopathic isolated growth hormone deficiency (IIGHD) who tested GH sufficient in mid-puberty (inclusion moment for this study).Aim: To assess potential differences in QoL between patients with IIGHD who discontinued treatment and those who continued ...

First report of a case of Wernicke Encephalopathy due to Acute Avoidance and Restrictive Food Intake in an Adolescent with insatiable hunger due to Melanocortin 4 Receptor Deficiency: a seemingly contradictory combination

E.P.L. van der Walle Eline , Deruyter Sarah , F. Neuteboom Rinze , L.T. van den Akker Erica

Background: Wernicke Encephalopathy (WE) is an acute life-threatening neuropsychiatric disorder caused by vitamin B1 (thiamine) deficiency. Although commonly associated with alcohol abuse in adults, it can also arise from non-alcoholic causes. WE is rarer in children. To our knowledge, WE has never been described in patients with extreme insatiable hunger due to genetic obesity, which seems paradoxical. We present a case of WE due to acute avoidance, restricti...

The effects of dextroamphetamine treatment in children with hypothalamic obesity

Samaan J , Welling MS , de Groot CJ , Abawi O , Burghard M , Kleinendorst L , van der Voorn B , van Haelst MM , Oude Ophuis B , Kamp GA , Rotteveel J , van Schouten-Meeteren AYN , van den Akker ELT , van Santen HM ,

Introduction: Children with hypothalamic dysfunction, e.g. due to a genetic or acquired cause such as suprasellar tumours, often suffer from hyperphagia and/or decreased resting energy expenditure (REE). This process induces uncontrollable weight gain, resulting in severe hypothalamic obesity (HO). No effective treatment is available yet for HO. Amphetamines are psychostimulants that are known for their appetite reducing and REE stimulating side effects. Here,...

MRI Changes in Time after Cranial Irradiation, and their Relation with Pituitary Function in Survivors of Childhood Medulloblastoma

Background: Hypothalamic-pituitary (HP) deficiencies are frequent in childhood brain tumor survivors (CBTS) after cranial radiation. There is currently no consensus on the most optimal way to screen for HP dysfunction regarding diagnostic tests or time interval. It is not known whether MRI changes in time in the HP-region or in brain volume are predictive of HP dysfunction.Aim: To quantify changes in the HP-region and in brain volume on MRI in CBTS after...

Withdrawing growth hormone treatment at mid-puberty in idiopathic isolated growth hormone deficiency: baseline characteristics in patient-preference design study

Background: The majority of children diagnosed with idiopathic isolated growth hormone deficiency (IIGHD) show a normal growth hormone (GH) secretion (assessed by GH stimulation tests) when retested at near adult height (NAH). It appears plausible that if normal stimulated GH secretion is observed in mid-puberty, continuing recombinant human GH (rhGH) treatment may only have a minor effect on NAH. The effect on NAH has never been investigated in a prospective ...

Global recall of a growth hormone jet delivered device: experiences with children forced to switch from a needle free system to a growth hormone device with needle.

P. van Eck Judith , S. Renes Judith , J.C. Sas Theo , L.T. van den Akker Erica , C.M. van der Kaay Daniëlle

Introduction: Growth hormone (GH) treatment is essential for growth in children with GH deficiency. Also short children born small for gestational age (SGA), and children with syndromes like Turner Syndrome (TS), Noonan Syndrome (NS) and Silver Russel Syndrome (SRS) can benefit from GH treatment. For children with needle anxiety GH delivered by a jet device can be a solution for the daily subcutaneous treatment for many years. In 2021, a global recall of the o...

Age-Specific Reference Values for Plasma FT4 and TSH Concentrations in Healthy, Term Neonates at Day Three to Seven, and 13 to 15 of Life

Background: Congenital hypothyroidism (CH) is a common and preventable cause of mental retardation in children, and is detected using dried blood spots in many neonatal screening programs. Upon suspicion of CH, plasma free thyroxine (FT4) and thyroid stimulating hormone (TSH) concentrations are measured. CH can be of thyroidal or central origin (CH-T and CH-C, respectively). While CH-T diagnosis is based on an elevated plasma TSH in combination with a low FT4,...
