Disorders of sex development (DSD) are those congenital conditions in which development of chromosomal, gonadal, or anatomical sex is atypical. The aim of this study was to characterize the histology of 46,XX DSD prepubertal gonads. We studied 25 gonads of fourteen 46,XX DSD patients. The age of biopsy/gonadectomy was 1.17 (0.08–4.17) years (median and range). Molecular studies confirmed the absence of SRY by PCR and/or MLPA in blood samples of all patients and i...

Background: Carriers of germline DICER1 mutations are predisposed to a rare cancer syndrome, the DICER1 syndrome, associated with tumors such as pleuropulmonary blastoma (PPB), ovarian Sertoli-Leydig cell tumors (SLCT), multinodular goiter (MNG), cystic nephroma (CN), embryonal rhabdomyosarcoma (ERMS) or primitive neuroectodermic tumor. DICER1 is involved in the generation of microRNAs (miRNAs), short, double-stranded, non-coding RNAs that modulate gene expression at ...

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...

Cytokines and the Impairment of Puberty

Shlyachova Natalia , Turchina Svetlana

The changes of the immune reactivity, the production of hormones and the neuroendocrinal regulation of immune homeostasis are the entities closely connected with the puberty. There is evidence for the role of cytokines in securing of intersystemic interaction as well as for the influence of reproductive hormones on the cytokine production. However, the question as to the role of cytokine in the formation of delayed puberty continues to be relevant.<stron...

Introduction: PseudoCushing is an unusual pathology. Among adults several cases have been published, however, in paediatrics it is unusual.Objective: Description of a PseudoCushing case from a patient admitted in a hospital and results from a study to discard secondary hypercortisolism due to stress.Patients and methods: 13 years old patient that it is admitted in hospital due to v...

Use of PDE5 inhibitors as a potential treatment for isolated growth hormone deficiency caused by alternate splicing of GH1 gene.

Pandey Amit , Natalia Rojas Velazquez Maria

Mutations in the GH1 gene cause isolated growth hormone deficiency (IGHD) by affecting production, secretion, and stability of growth hormone as well as its binding to GHR. A smaller isoform of GH1 is inactive and is linked to IGHD. While studying the impact of small GH isoform, we noticed that cells with the short 17.5 kD version of GH looked different from the control cells. We found that the production of short GH isoform distorts the cell morphology, contributing to detrim...

Insulin Therapy in the Pediatric Age–Group

Mikhno Hanna , Solntsava Anzhalika , Volkova Natalia

Objective: Continuous subcutaneous insulin therapy (CSII) and therapy with insulin analogues are considered to provide physiological insulin replacement, which results in improvement of diabetes control. Rate metabolic compensation of diabetes mellitus (DM) in children on IPT and basal-bolus insulin therapy on the level HbA1c and self-control of glycemia.Methods: We analyzed retrospectively 88 histories of disease children with type 1 DM. The patients we...

Health services for children with diabetes mellitus in Dnipro, Ukraine

Yenhovatova Viktoria , Globa Evgenia , Zelinska Natalia

As of 2022, the Ukraine Pediatric Diabetes Register (UPDR) contained children aged <18 years with DM1- 11014 (1 in 677), with DM2 – 51 (1 in 146274), with neonatal diabetes (ND) – 69 (1 in 108115), and 59 cases (1 in 126440) with MODY. Most studies focus on such parameters as HbA1c, acute complications and quality of life, whereas investigations of the frequency of chronic DM1 complications and glycemic control for internally displaced persons (IDP) have not bee...
