Background: Androgen insensitivity syndrome (AIS) is an X-linked hereditary disease with AR gene loss-of-function mutations in 46,XY patients. They undergoes poor development of secondary sex characteristics, except for breast development at puberty. AIS patients are prone to develop germ cell cancer, even though with lower incidence than in dysgenetic gonads secondary to defects in organogenesis.Case presentation: We described a 3-years-old gir...

Objectives: Pediatric obesity (PO) leads in adulthood to chronic high-risk pathologies, if not adequately identified and addressed. The anthropometric methods for evaluating PO have well-described limits. One of the most recently proposed indexes to better locate and evaluate PO is the neck circumference (NC). We have verified the relationship between NC, body mass index (BMI), waist circumference (WC) and some laboratory parameters, with the aim of defining t...

Background: During the 1st months of postnatal life serum luteinizing hormone (LH) levels in girls are lower than in boys. The mechanism of this sex difference is not known. It has been proposed that foetal or perinatal androgenic steroids have an effect on the control of LH secretion.Objective and hypotheses: To study the possible influence of high levels of androgens on serum gonadotropins during the 1st months of life in a cohort of nine 46,XX testicu...

Background: The SRY protein is a transcription factor that contains a high mobility group (HMG) homeobox domain which possesses sequence-specific DNA binding activity and regulates other genes involved in male sex determination pathway. The majority of the identified mutations occurred within the HMG-box motif. There are few reports of pedigrees with familial transmission.Objective and Hypotheses: To describe a paternally transmitted novel SRY mutation w...

Background: Nail-Patella syndrome (NPS) or hereditary onycho-osteodysplasia (OMIM: 161200) is an autosomal dominant disorder characterized by nail and elbow dysplasia, patellar aplasia or hypoplasia, nephropathy and intra-ocular hypertension. The diagnosis confirmes by pathogenic variant in the LMX1B gene. There are reports of short stature in patients with this syndrome, however, data of the use of somatropin have not been presented. We describe the ...

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 ...

Introduction: Kisspeptin stimulates the gonadotropin releasing hormone (GnRH) neurons in hypothalamus initiating puberty. However, it is not known whether GnRH inhibits kisspeptin secretion by negative feedback and whether there are any associations between circulating levels of kisspeptin and other hormones, like ghrelin, important for the onset of puberty.Methods: Thirteen girls with suspected central precocious pubert...
