Background: Congenital hypogonadotropic hypogonadism (HH) is a rare but clinically and genetically heterogeneous disease characterized by an absent or incomplete puberty and infertility. The association of HH with hyposmia or anosmia is defined as Kallmann syndrome. Molecular genetic testing of HH is valuable, as it can prompt the treatment in adolescence.Objective and hypotheses: To identify causative variants in genes associated with HH in a cohort of ...

Background: Gonadotropin releasing hormone (GnRH)-secretion is not only regulated by neuronal factors but also by astroglia cells via growth factors (transforming growth factor α (TGFα), neuregulin (NRG)), prostaglandin E2 (PGE2) and the erbB receptor family. Mutations of TGFα and erbB1 result in an impaired reproductive capacity. Mice show a characteristically skin phenotype with wavy hair and curly whiskers. The rat strain SPRD-Cu3 (curly) shows a sim...

Background: In pediatric patients multiple pituitary hormone deficiency (MPHD) can be caused by mutations in pituitary-specific transcription factors. Among those, mutations in PROP1 gene account for ~50% of genetically determined cases of CPHD. Regarding morphology, the anterior pituitary can be normal, hypo-/aplastic or enlarged.Results: We present two unrelated patients referred for evaluation of growth retardation. Both had profound growth retardatio...

Introduction: The 46,XX testicular disorder of sex development (DSD) is a rare genetic condition and clinical phenotype shows complete sex reversal from female to male. The sex-determining region Y (SRY) gene can be identified in most 46,XX testicular DSD patients, but approximately 20% of patients are SRY-negative. We report a 1.3 -year old SRY/negative 46,XX boy with complete sex reversal caused by SOX3 duplication.Case report:...

Introduction: The increasing prevalence of obesity has become a major global health issue. Clustering of cardiometabolic risk factors in obese adolescents is associated with reduced life expectancy and impaired quality of life. Due to serious impact of obesity on cardiometabolic health, effective treatment strategies are intensively sought after.Objectives: The aim of this retrospective cross-sectional study was to exami...

Introduction: Morphological characteristics of the glucose concentration curve during an oral glucose tolerance test (OGTT) may reflect differences in insulin secretion and sensitivity. Whether the shape of the glucose curve and time to peak glucose concentration can be used as indicators of beta cell function and markers of type 2 diabetes risk in obese adolecents is still uncertain.Aims/hypothesis: The purpose of this cross-sectional study was to asses...

Background: Controversial findings about the metabolic profile in newborns depending on the length of gestation and size at birth have been reported.Objective and hypotheses: Insulinemia, adiponectin, and leptin levels are different in children born prematurely and SGA neonates compared to term normal newborns.Method: 196 healthy newborns were studied at the age 3-4 days. Birth weight (BW), birth length (BL), BMI, ponderal index (P...

Introduction: The main reason for Newborn screening (NBS) for congenital adrenal hyperplasia (CAH) is to prevent adrenal insufficiency that can lead to life-threatening conditions. On the other hand, screening programmes are not always sensitive and effective enough to detect the disease. We aimed to evaluate the specificity, sensitivity and efficiency of the national NBS for CAH in Lithuania.Methods: retrospective study...

Background: The Xp21 contiguous gen deletion syndrome is a rare disorder which is characterized by complex glycerol kinase deficiency, congenital adrenal hypoplasia, intellectual disability and Duchenne muscular dystrophy. It is caused by partial deletion of Xp 21. On Xp21 several genes are located contiguously, such as NR0B1/DAX1, dystrofin gen and gene for glycerol kinase, and the clinical features depend on the size of the deletion. The major clinical manif...

Introduction: Obesity and vitamin D deficiency are global public health problems. There is evidence of a reciprocal link between vitamin D deficiency and obesity. Both conditions are risk factors for the development of chronic diseases, primarily insulin resistance and diabetes mellitus type 2, and contribute to a decrease in physical fitness (PF). The aim of this study was to determine the effectiveness of vitamin D supplementation on PF of obese children dur...
