Value of antimullerian hormone (AMH) in the diagnosis of precocious puberty: revaluation of the covid-19 post-pandemic cohort

Diez-Lopez Ignacio , Aurora Vilella San Martín Leyre , Sarasua Miranda Ainhoa , San Martin Orayen Amaia , Maeso Mendez Sandra

During the pandemic, an increase in the cases of premature thelarche consultations was observed. Our group published a series in 2021 of 75 cases. This effect could have been caused by an increase in body fat mass in girls, suggesting a “trigger effect” in the activation of the gonadal axis, causing an increase in the number of cases of early puberty (SEEP Oviedo 2022). AMH has been correlated as a predictor of the moment of menarche (doi: 10.1515/jpem-2014-0521)</...

De Novo Formation of Neutralizing IGF-I Antibodies During rhIGF-1 Treatment in a Girl with IGFALS Deficiency as Distinct Adverse Event Interfering with Growth Promotion

Mittnacht Janna , Breil Thomas , Choukair Daniela , Duffert Christin , Hwa Vivian , Rosenfeld Ron , Bettendorf Markus

Background: IGFALS deficiency is a rare cause of GH insensitivity (GHI). We report a German girl with short stature who was born as 2nd child at 40 weeks of gestation. Her Caucasian parents were unrelated and healthy (target height 168 cm, SDS 0.2). She was born appropriately sized for gestational age (49 cm, SDS -1.2; 2950 g, SDS-1.2). Height (104.8 cm; SDS -2.94) and height velocity (5.1 cm / year; SDS -1.67) were reduced at the age of 6 years.</p...

Long-Term Follow-Up Study for a Boy with Floating–Harbor Syndrome Due to a de novo Novel Heterozygous SRCAP Mutation

Ma Huamei , Zhang Jun , Guo Song , Li Yanhong , Chen Qiuli , Chen Hongshan , Du Minlian

Background: —Floating-Harbor syndrome(FHS) is a rare autosomal dominant genetic disorder associated with heterozygous mutations in SRCAP gene. The SRCAP protein activates the cAMP-response element binding protein-binding protein(CREBBP) gene that is involved in the regulation of cell growth and division.Objective: To report on long-term follow-up data of a boy with FHSMethods:...

A Novel Reversible Albumin-Binding GH Derivative Possesses a Promising Once-Weekly Treatment Profile in Children with GH Deficiency

Zuckerman-Levin Nehama , Gucev Zoran , de Schepper Jean , Rasmussen Michael Hojby , Battelino Tadej , Olsen Minna Braendholt , Savendahl Lars

Background: GH administration restores normal growth in children with GH deficiency (GHD). However, current daily s.c. injection treatment regimens may be inconvenient leading to impaired adherence and subsequently suboptimal treatment outcomes. NNC0195-0092 is a novel, reversible albumin-binding GH developed for once-weekly administration.Objective and hypotheses: This was a randomised, open-label, active-controlled, dose-escalation trial (NCT01973244) ...

Background: Congenital hypothyroidism (CH) comprises a heterogeneous group of disorders that includes diseases of the hypothalamo-hypophyseal system. The latter are missed on TSH based screening programs leading to increased morbidity and mortality. Additional T4 determinations, allows an early detection of CH of central origin (CH-C).Objective and hypotheses: To report the findings of a neonatal screening program based on determination of TSH...

Autosomal dominant hypocalcemia: A diagnostic and therapeutic challenge

Ariza-Jimenez Ana-Belen , Ariza-Jimenez Jose-Antonio , Azpilicueta Idarreta Maria , de la Camara Moraño Carmen

Introduction and Aims: Autosomal dominant hypocalcemia or type V Bartter syndrome is characterized by hypocalcemia, low parathyroid hormone (PTH), and calciuria, which marks its prognosis due to the risk of nephrocalcinosis. It is caused by activating mutations in the calcium-sensing receptor (CASR) gene (3q21.1), which is expressed in the parathyroid and renal tubules, causing salt and potassium loss, due to the inhibition of the ROMK and NKCC2 channels. We s...

Pump management of genetic and autoimmune diabetes under 1 years old: two case reports.

Martino Mariangela , Gutierrez De Rubalcava Doblas Joaquin , Cusinato Maria , Gabrielli Claudia , Negri Arianna , Righetto Elena , Moretti Carlo

Handling diabetes at a very early age is difficult, even more when a complementary diet has not yet started. There is increasing evidence supporting the use of CSII in infants but some tricks could be useful.Infant 1: 10 mo, admitted in cardiac arrest. ROSC after 3 minutes, severe DKA (pH 6,95). Transferred to PICU, received also plasma transfusions. Day 2: CGM Dexcom G6 was started and tests for pancreatic autoimmunity and genetic of ne...

Hypomethylation within the Imprinted Dlk1 - Dio3 Domain: a Potential Regulatory Mechanism of Pre and Postnatal Growth

Prats-Puig Anna , Carreras-Badosa Gemma , Bassols Judit , Cavelier Patricia , Magret Agnes , Sabench Cristina , Zegher Francis de , Ibanez Lourdes , Feil Robert , Lopez-Bermejo Abel

Background: Genomic imprinting causes genes to be expressed or repressed depending on their parental origin. The 1-Mb DLK1-DIO3 imprinted domain is located on human chromosome 14. Gene expression along this cluster is regulated by an intergenic differentially methylated imprinting control region (‘IG-DMR’). In mice, altered gene dosage within this cluster is associated with alterations in embryonic and placental growth.Objective and hy...

Hypermethylation at the Imprinted C19mc Microrna Cluster: A New Link between Maternal Metabolism and Infant’s Growth

Prats-Puig Anna , Carreras-Badosa Gemma , Bassols Judit , Girardot Michael , Carrion Empar , Gehmis Radu , Zegher Francis de , Ibanez Lourdes , Feil Robert , Lopez-Bermejo Abel

Background: Maternal obesity can have long-term consequences for the offspring’s health, including increased risk of type-2 diabetes and cardiovascular disease. The C19MC imprinted locus on chromosome 19q13.4 comprises a cluster of 46 microRNAs, which are usually expressed only in the placenta and from the paternal allele exclusively. Besides its role favouring trophoblast migration, the C19MC locus is deregulated in several human cancers. It is unknown ...

Background: Pediatric thyroid cancer has characteristics that are distinct from adulthood thyroid cancer. Due to its very low prevalence, little is known about the genetic characteristics of pediatric follicular thyroid cancer (FTC).Methods: We investigated genetic alterations in tumor tissues from 15 patients aged < 20 years (median: 14.3 years; range: 2.4-19.0 years) using multifaceted approaches.
