Background: The presence of a thyroid nodule (TN) is a rare clinical condition during childhood and adolescence. In children, classically was considered malignant and total thyroidectomy was recommended whenever a TN was detected or in the case of cold nodules. There are not long time series in children, but recent clinical guidelines recommend an initial management as in adults.Objective and hypotheses: Review TN in children in our area.<p class="ab...

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 ...

A 15-year-old boy, an active sportsperson, presented to an orthopaedic surgeon with a painful left elbow. He had no history of preceding trauma, had full range of motion of his elbow and was systemically well. Imaging demonstrated extra articular calcification at the distal humerus. Serum phosphate was elevated at 2.53mmol/l [1.10-1.80] with calcium 2.48mmol/l [2.10-2.60] and tubular reabsorption of phosphate of 94.6% [82-100%]. He was then referred for endocrine assessment, w...

An 11 year 8-month-old girl presented to her oncologist with recent voice change and increased leg hair growth. She had a past history of pelvic rhabdomyosarcoma in 2012, at age 2, with relapse and local metastasis at age 4. Prior to original tumour treatment, oophoropexy had been performed, aiming to prevent ovarian radiation exposure. At time of the new complaint, she was receiving a trial treatment. Puberty was reported to have commenced at age 10, with 6-months of increase...

Introduction: Pituitary gigantism is caused by a somatotroph pituitary tumor that occurs before epiphyseal closure and is associated with increased morbidity due to the systemic effects of chronic hormonal excess. It is an extremely rare disease, with an estimated incidence of 8 per million person-years. Therapeutic modalities for pituitary gigantism are the same as those for acromegaly and include surgery, medication and radiation. Medical treatment plays an ...

Background: Pregnancy associated plasma protein (PAPP)-A2 is an insulin-like growth factor (IGF) binding protein (BP) protease that regulates IGF-1 availability, affecting postnatal growth. We have recently reported the first mutations in human PAPP-A2 causing short stature and changes in bone size and mineral density. However, the IGF system is involved in diverse physiological functions and to date it is unknown how mutations in PAPP-A2, which significantly reduce f...

Background: An activation cascade of specific genes sets up the initiation of sex determination leading in males to testes formation and synthesis of testicular hormones. Disruption of this gene cascade may cause a spectrum of 46,XY disorders/differences of sex development (DSD) phenotypes. Here we describe for the first time two sisters suffering from 46,XY DSD, who by whole exome sequencing revealed to carry a X-linked mutation in the StAR-related lipid transfer domain prote...
