Introduction: Pituitary adenomas (PPAs) are uncommon in childhood and adolescence, accounting for 2-6% of all intracranial neoplasms. Most data are based on case reports and only a few series have been reported. Delayed puberty, short stature, galactorrhea and weight gain are common features at presentation in pediatric patients. Functional tumors constitute a vast majority (90%) of PPAs including corticotropinomas in the first decade followed by relative upsu...

Background: Dyshormonogenic hypothyroidism is classically a monogenic disease with recessive inheritance. Thyroid dysgenesis showed a multigenic origin in a mouse model of double-heterozygous deletions of Nkx2.1/Pax8 transcription factor genes, suggesting a possible polygenic nature of certain cases of human hypothyroidism.Objective and Hypotheses: To investigate genetic traits of polygenic involvement in dyshormonogenic hypothyroidism,...

Introduction: The MAMLD1 gene is expressed in fetal and adult testes. It contributes to the development and formation of the male external genitalia in late stages of fetal organogenesis (week 8-12) and to testosterone biosynthesis. The pathogenic genetic variants of this gene determine a significant reduction in plasma testosterone concentrations, although they are not undetectable. Its most common phenotypic manifestation is hypospadias, also described in patients with micro...

Introduction: Congenital hypopituitarism is a heterogeneous disorder with isolated hormone deficiency(IPHD) or combined(CPHD). Main risk factors for CPHD include H-P abnormalities such agenesis corpus callosum(ACC), anterior pituitary hypoplasia(APH), ectopic posterior pituitary(EPP), pituitary stalk interruption(PSI), septo-optic dysplasia(SOD), and holoprosencephaly(HPE).Patients and Methods: Prospective and longitudin...

Introduction: Differential diagnosis of partial arginine vasopressin deficiency (P-AVPD) and primary polydipsia (PP) can be challenging. Arginine-stimulated copeptin concentrations have been used to differentiate between arginine vasopressin deficiency (AVPD) and PP, setting a copeptin value of 3.8pmol/L at 60 min as a cut-off point in adults.Objective: To evaluate the efficacy and safety of the arginine-stimulated test ...

Background: Congenital hyperinsulinism (CHI) is a rare disease affecting neonates, infants, and children. CHI is characterized by dysregulated insulin secretion resulting in severe recurrent hypoglycemia. Early treatment is necessary to limit the risk of neurologic and developmental sequelae. Current treatment options are limited and inadequate. Dasiglucagon (DASI) is a glucagon analog suitable for continuous subcutaneous infusion which has been shown to raise...

Background: Physical activity (PA) has been conclusively shown to reduce the incidence of diabetes in prior research. A 2,000 steps/day increment yielded hazard ratio (HR) 0.88 for incidence of diabetes 95% CI 0.78–1.00; P=0.046 (Garduno, 2022). Despite this, the role of different factors associated with higher adolescent after-school PA is understudied after the coronavirus pandemic, during which a greater proportion of parents worked remotely....

Novel CNS imaging techniques is a fast advancing field with frequent new developments in scanner’s hardware, protocols, clinical indications, and post-processing techniques. These techniques are designed to focus on the assessment of functional tissue characteristics, such as neuronal activity (functional MRI- fMRI), microstructural properties (diffusion tensor imaging-DTI) and tissue perfusion (DSC perfusion, ASL). fMRI reveals brain activation during performance of beha...

High-throughput biomolecular (omic) analyses enabled the simultaneous quantification of hundreds or thousands of transcripts, proteins, metabolites in a biological system, contributing to the identification of discriminatory multi-component molecular profiles of a pathophysiology. Molecular quantities being interconnected, even subtle differences in one can carry significance if viewed in the context of the observed changes in the rest of the molecules. We can now view molecul...

Background: GH therapy for GH deficient (GHD) children in Russia is fully state funded as part of the ‘Seven high expenditure diseases’ (7HED) federal program. Thus, it is important to thoroughly understand the disorder, including its epidemiology. In Russia, there are two parallel functioning registries: the official federal medical statistics (OFMS) which provides purely statistical information and the 7HED registry which must contain a patient’s data to make ...
