Background: Several years ago, we developed a recombinant cell bioassay to determine serum estrogenic bioactivity (EBA). In addition to its physiological interest, EBA could be a good marker of endocrine-disrupting compounds (EDCs) with estrogenic activity and thus would be useful in the field of environmental-related endocrine diseases.Aims and objectives: To characterise the type of substances that mediate estrogenic activity.Met...

Background: The oestrogenic activity of endocrine-disrupting compounds (EDCs) has been reported to be associated with premature thelarche (PT) and precocious puberty. Some years ago, we developed a recombinant cell bioassay to determine serum estrogenic bioactivity (EBA) that is useful in physiology, as well as in the field of the environmental-related endocrine diseases. We recently improved the assay with an evaluation of EBA before and after incubation with estrogen recepto...

Background: Congenital adrenal hyperplasia, one of the most frequent autosome recessive disorders, is caused by defects in steroidogenic enzymes involved in the cortisol biosynthesis. Approximately 95% of cases are caused by a deficiency of the 21-hydroxylase enzyme. Its deficiency leads to androgen excess, consequently, to virilization and rapid somatic growth with accelerated skeletal maturation. Mutations in CYP21A2 are responsible for different forms of 21-hydroxylase defi...

Background: Achondroplasia is a skeletal dysplasia being the most common cause of rhizomelic dwarfism.Case presentation: We present a 10 years old boy who was first diagnosed prenatally. He had a mutation c1138G>A in the gene FGFR3 in a heterozygotic constellation. His IGF1 levels and IGFBP3 were normal. Two stimulation tests for GH were performed with normal levels of the hormone. His psychomotor development was adequate for his age except for speec...

Background: Congenital glucose–galactose malabsorbtion is a rare autosomal recessive disorder of intestinal transport of glucose and galactose. It is characterized by watery diarrhoea, dehydration, failure to thrive, or early death without appropriate dietary treatment.Case presentation: The patient was 15 days old when he was admitted to the hospital because of continued, severe, watery, acidic diarrhoea and hypernatremic dehydration. The abnormal ...

Background: According to recent European and Russian monitoring hypospadias and cryptorchidism are the most frequent malformations of the urogenital system in children in the general population. Currently there is a lack of information about the impact of assisted reproductive technologies (ART) on the development of congenital malformations, including the urogenital system, although the presence of this abnormality could lead to male reproductive disorders.</...

Background: Hashimoto’s thyroiditis is a common autoimmune disease in pubertal and adolescent girls. In the past years the incidence of this autoimmune disease of the thyroid gland has increased.Objective and hypotheses: We present a 12.5 year old girl who had her first visit at our Pediatric Endocrinology Department at the age of 10 years due to short stature and clinical signs of hypothyroidism. Her height was – 3SD SDS and her BMI was 12.7. ...

Background: Hypophosphatasia (HP) is a rare inherited disorder characterised by defective bone and teeth mineralization because of deficient serum and bone alkaline phosphatase activity due to mutations in the tissue-nonspecific ALP (TNALP) gene. Infantile HP (IHP) is one of the six recognized clinical forms according to age at presentation and clinical features. IHP is characterised by skeletal abnormalities due to demineralization and rachitic changes in the metaphyses, prem...

Background: Iodine deficiency has multiple adverse effects in humans, termed iodine deficiency disorders, due to inadequate thyroid hormone production. Iodine deficiency during pregnancy and infancy may impair growth and neurodevelopment of the off-spring and increase infant mortality.Objectives: To evaluate effects of iodine supplementation in pregnant, lactating women and their infants at the East of Ukraine.Methods: Target group...
