Unusual circumstance for craniopharyngioma discovery on meningoencephalitis: a pediatric case report.

Background: Craniopharyngioma is a rare condition in children, but it is the most frequent tumor that occurs in the hypothalamic pituitary region. Chemical meningitis has been described as an uncommon postoperative complication, but no chemical meningitis due to a spontaneous rupture leading to craniopharyngioma diagnosis in children has been reported.

Case Presentation: This is a case of a 13-year-old boy presenting with fever, vomiting and headache for two days.

Reversal of malignant ADAR1 splice isoform switching with Rebecsinib.

Adenosine deaminase acting on RNA1 (ADAR1) preserves genomic integrity by preventing retroviral integration and retrotransposition during stress responses. However, inflammatory-microenvironment-induced ADAR1p110 to p150 splice isoform switching drives cancer stem cell (CSC) generation and therapeutic resistance in 20 malignancies. Previously, predicting and preventing ADAR1p150-mediated malignant RNA editing represented a significant challenge.

Inflammation-driven deaminase deregulation fuels human pre-leukemia stem cell evolution.

Inflammation-dependent base deaminases promote therapeutic resistance in many malignancies. However, their roles in human pre-leukemia stem cell (pre-LSC) evolution to acute myeloid leukemia stem cells (LSCs) had not been elucidated. Comparative whole-genome and whole-transcriptome sequencing analyses of FACS-purified pre-LSCs from myeloproliferative neoplasm (MPN) patients reveal APOBEC3C upregulation, an increased C-to-T mutational burden, and hematopoietic stem and progenitor cell (HSPC) proliferation during progression, which can be recapitulated by lentiviral APOBEC3C overexpression.

Acquired von Willebrand's syndrome caused by primary hypothyroidism in a 5-year-old girl.

Background Acquired von Willebrand's syndrome (aVWS) associated with hypothyroidism is rare in children and more often diagnosed during the peripubertal period in the context of Hashimoto's thyroiditis. Case presentation A 5-year-old girl was referred to the paediatric haematology unit for rectal bleeding, anaemia and prolonged activated partial thromboplastin time (aPTT). Her developmental and learning skills were normal.

Noonan syndrome males display Sertoli cell-specific primary testicular insufficiency.

Context Abnormalities in the hypothalamo-pituitary-gonadal axis have long been reported in Noonan syndrome (NS) males with only few data available in prepubertal children. Objective The aim of this study was to describe the gonadal function of NS males from childhood to adulthood. Design It is a retrospective chart review.

Graves' disease in children.

R1 The diagnosis of Graves' disease in children is based on detecting a suppression of serum TSH concentrations and the presence of anti-TSH receptor antibodies. 1/+++. R2 Thyroid ultrasound is unnecessary for diagnosis, but can be useful for assessing the size and homogeneity of the goiter.

Wilms tumor, pleuropulmonary blastoma, and DICER1: case report and literature review.

Background: Pleuroblastoma (PPB) is a rare pediatric tumor which, in 30% of cases, is associated with cystic nephroma. It has been recently linked to the DICER1 mutation as part of a predisposition syndrome for various tumors. However, if DICER 1 anomalies have been reported in patients with Wilms tumor (WT), to date, no cases of PPB, WT, and DICER1 mutations have been reported in the same patient.

Pituitary Stalk Interruption Syndrome from Infancy to Adulthood: Clinical, Hormonal, and Radiological Assessment According to the Initial Presentation.

Background: Patients with pituitary stalk interruption syndrome (PSIS) are initially referred for hypoglycemia during the neonatal period or growth retardation during childhood. PSIS is either isolated (nonsyndromic) or associated with extra-pituitary malformations (syndromic).

Objective: To compare baseline characteristics and long-term evolution in patients with PSIS according to the initial presentation.

Comparison of response to 2-years' growth hormone treatment in children with isolated growth hormone deficiency, born small for gestational age, idiopathic short stature, or multiple pituitary hormone deficiency: combined results from two large observational studies.

Background: Few studies have compared the response to growth hormone (GH) treatment between indications such as isolated growth hormone deficiency (IGHD), born small for gestational age (SGA), idiopathic short stature (ISS), and multiple pituitary hormone deficiency (MPHD). The aim of this analysis of data, collected from two large ongoing observational outcome studies, was to evaluate growth and insulin-like growth factor-I (IGF-I) response data for children of short stature with IGHD, MPHD, SGA, or ISS following two years of treatment with the recombinant GH product Norditropin® (Novo Nordisk A/S, Bagsværd, Denmark).

Methods: Analysis of auxologic data from two ongoing prospective observational studies, NordiNet® International Outcomes Study (NordiNet® IOS) and NovoNet®/American Norditropin®

Studies: Web-enabled Research (ANSWER) Program®.

Gender influences short-term growth hormone treatment response in children.

Background: Gender may affect growth hormone (GH) treatment outcome. This study assessed gender-related differences in change from baseline height standard deviation scores (ΔHSDS) after 2 years' GH treatment.

Methods: Data from two observational databases were analyzed - the NordiNet® International Outcome Study (NordiNet® IOS) and the American Norditropin Studies: Web Enabled Research Program (ANSWER Program®).

Elevated insulin-like growth factor-I values in children with Prader-Willi syndrome compared with growth hormone (GH) deficiency children over two years of GH treatment.

Background: Children with Prader-Willi syndrome (PWS) are routinely treated with GH and have a response comparable with that observed in children with GH deficiency (GHD).

Objective: The objective of the study was to compare changes in serum IGF-I, IGF binding protein 3 (IGFBP-3), IGF-I to IGFBP-3 molar ratio, and growth velocity during the first 2 yr of GH therapy in PWS and GHD children.

Subjects And Methods: Thirty-three children with PWS (14 boys, 4.

Long-term evolution of endocrine disorders and effect of GH therapy in 35 patients with pituitary stalk interruption syndrome.

We report long-term evolution of endocrine functions and the results of GH treatment in 35 patients (26 male and 9 female) with pituitary stalk interruption. At diagnosis, mean chronological age was 4.8 +/- 2.

Adolescents with partial growth hormone (GH) deficiency develop alterations of body composition after GH discontinuation and require follow-up.

It is now a consensus to resume GH treatment in adolescents with severe GH deficiency (GHD) at retesting to prevent the occurrence of adult GHD syndrome. However, we do not have any data on the follow-up of adolescents with nonsevere GHD at completion of treatment. This report presents preliminary data from a 1-yr prospective study that includes the first 91 patients retested.
