Background: GnRH neurons originate outside the CNS in the olfactory placode and migrate into the central nervous system, becoming integral components of the hypothalamic-pituitary–gonadal axis (HPG).Objective and hypotheses: We hypothesize that gene(s), whose products are important for pubertal development can be identified via autozygosity mapping together with whole exome sequencing in patients with idiopathic hypogonadotrophic hypogonadism (IHH)/...

Background: Activation of the Wnt/β-catenin pathway is frequent in adrenocortical tumors (ACTs). This pathway and DAX1, a negative regulator of SF1 expression, control adrenal stem/progenitor cells, which can be involved in ACTs formation.Objective: To analyse the association between the Wnt/β-catenin pathway and the expression of a stem cell marker (NANOG), STAT3, DAX1 and SF1 in ACTs.Methods: Patients:...

Background: Gonadectomy is generally postponed until early adulthood in complete androgen insensitivity syndrome (CAIS) and close surveillance of gonads in situ proposed in males with partial AIS (PAIS). Delaying gonadectomy further is controversial given the lack of data regarding germ cell cancer (GCC) development in adulthood and the absence of biomarkers for noninvasive GCC screening.Aims and objectives: To study the prevalence of invasive G...

Copy Number Variants in Patients with Congenital Hypopituitarism Associated with Complex Phenotypes

Background: The aetiology of congenital hypopituitarism (CH) is unknown in the majority of patients. In our cohort of 200 cases, it was possible to establish the genetic cause in only 13 patients (6.5%). Copy number variants (CNVs) have been implicated as the cause of genetic syndromes with previously unknown aetiology.Objective: To study the presence of CNVs and its relevance in patients with CH of unknown cause associated with complex phenotypes.<p...

Background: Congenital diabetes insipidus (DI) can be due to mutations in the arginine vasopressin (AVP) gene (familial neurohypophyseal DI), the AVP receptor type 2 (AVPR2) or aquaporin 2 (AQP2) genes (congenital nephrogenic DI, NDI). The clinical manifestation of congenital NDI, especially the response to AVP, can vary greatly depending on the functional effect of the AVPR2 mutation. Here we present two male siblings with NDI and partial response to ddAVP.<p class="abste...

Objective: KIGS (Pfizer International Growth Survey) was a large, international database of pediatric patients who received recombinant human growth hormone (rhGH) as prescribed in real-world clinical settings. This analysis evaluated the long-term safety and efficacy data from all participants until KIGS close in 2012.Methods: Children with growth disorders and treated with rhGH (Genotropin® [somatropin]...

Aim: Childhood obesity has become extremely important issue worldwide. The aim of this study was to determine associations between data from bioimpedance analysis with the antrophometric measurements and biochemical results obtained from children and adolescents with severe obesity.Study population and Methods: Study group consisted of 128 children recruited in four regional reference centers including 70 girls (54.7%) a...

Occurrence of cardiovascular risk factors in Polish children and adolescents with severe obesity. Preliminary results of the Polish-German study project on severe early-onset obesity

It is estimated that 1-5% of children and adolescents in Europe suffer from severe obesity (corresponding to an adult BMI > 40 kg/m2). However, in risk stratification, the occurrence of metabolic complications is more important than BMI itself. The study aimed to assess the occurrence of cardiovascular risk factors in a cohort of children and adolescents with severe obesity.Patients and Methods: The analysis included 140 patients (75 ...

Background: Fatty liver disease in children and adolescents is the most common cause of chronic liver disease in many countries. Criteria for a diagnosis of pediatric metabolic associated fatty liver disease (MAFLD) are based on hepatic steatosis in ultrasound, blood biomarkers or liver biopsy in association with one of the three criteria: excess adiposity (overweight, obesity or abdominal obesity), prediabetes or type 2 diabetes, or evidence of metabolic dysr...
