Background: Hypergonadotropic hypogonadism (HH) is an hallmark of Turner Syndrome (TS) and hormone replacement therapy (HRT) is often required for pubertal induction; this retrospective study highlights the pituitary-gonadal axis during infancy (<5 years), childhood (5–10.9 years) and adolescence (> 11 years) in a cohort of TS patients enrolled between February 1999 to March 2023. Our aim is to underline the diagnostic role of Gonadotropins as a ma...

Background: Langerhans cell histiocytosis (LCH) is a rare disease with an incidence of less than 10 per million, and characterized by the clonal proliferation of pathogenic Langerhans cells. The clinical courses are diverse, ranging from spontaneously remitting single organ disease to life-threatening multisystem involvement. One of the serious complications of LCH is diabetes insipidus (DI), and patients with CNS-risk lesions had higher cumulative incidence of DI. On the othe...

Background: GNRHR gene mutations are responsible for development to normosmic idiopathic hypogonadotropic hypogonadism (iHH) and known to be the most frequent cause of this condition. Nevertherless, the reported frequency of GNRHR mutations in iHH patients estimated to be as low as 3-6%.Objective: To evaluate the frequency of GNRHR gene defects in a heterogeneous group of Russian patients with iHH and described the p...

Introduction: Water and electrolyte disorders due to anterior and posterior pituitary deficiencies are common in children which are referred with intracranial tumors, especially arising from suprasellar and pituitary regions. But the prevelance and affecting factors of these disorders are not clear. We aimed that to determine the prevelance of postoperative water and electrolyte disorders and affecting factors in pediatric patients with intracranial tumors.<p class="abstex...

Background: Central diabetes insipidus (DI) is a well-known complication of CNS trauma or tumors, but is a rare complication of hypothermia. Review of the literature reveals scant case reports of DI as a complication of therapeutic hypothermia after cardiopulmonary resuscitation or head injury, but to date there has been no mention of DI resulting from hypothermia alone.Objective and hypotheses: Severe hypothermia alone may constrict CNS blood flow, mimi...

Background: Familial central diabetes insipidus (DI), usually an autosomal dominant disorder, is caused by mutations in arginine vasopressin–neurophysin II (AVP-NPII) gene that leads to aberrant preprohormone processing and gradual destruction of AVP-secreting cells.Objective and hypotheses: To determine clinical and molecular characteristics of patients with familial central DI from two different families.Method: The diagnosi...

Background: Mutations in PROP1 are the most common known genetic cause of congenital multiple pituitary hormone deficiency (MPHD).Objective and hypotheses: Aim of our study was to clinically and genetically characterize a cohort of Lithuanian patients with MPHD.Method: Seventy-six Lithuanian MPHD patients were tested for PROP1 gene by Sanger sequencing. Hormonal investigations, pituitary imaging and GH therapy wer...

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...

Background: Several studies found a high prevalence of sleep disorders in PWS patients. It is assumed that Prader-Willi Syndrome (PWS) patients are at a high risk of sleep disordered breathing, such as obstructive sleep apnea (OSA), because of their childhood obesity, associated with muscle hypotonia, leading to upper airway collapse.Objective and hypotheses: We studied a group of PWS children (genetically confirmed, non-GH-treated) who performed complet...

Objective: To characterise clinical presentation of congenital isolated ACTH deficiency.Methods and results: Clinical and anthropometric data were obtained. Biochemical liver function parameters, blood glucose, insulin, TSH, free thyroxin (FT4), GH, cortisol, and ACTH levels were analyzed. POMC and TBX19 genes were analysed by Sanger sequencing. The girl was born at full-term with normal weight and length. The parents are cousins. At birth cra...
