Hyperthyroidism in adolescents

Niedziela Marek

The term “hyperthyroidism” is a form of thyrotoxicosis due to inappropriately high synthesis and secretion of thyroid hormone(s) by the thyroid. The leading cause of hyperthyroidism in adolescents is Graves’ disease; however, one should also consider other potential reasons such as toxic adenoma (TA) or a toxic multinodular goiter (TMNG), and other rare disorders leading to excessive production and release of thyroid hormones. The term “thyrotoxicosis&#...

Endocrine disorders of puberty

Niedziela Marek

Puberty is a process in humans that leads to the development of secondary sexual characteristics and reproductive capabilities. The physical changes of puberty result from two separate and independent but overlapping processes: gonadarche and adrenarche. The activation of hypothalamic-pituitary-gonadal (HPG) axis plays a key role in gonadarche whereas body weight and body mass index are postulated as triggering the adrenarche. The impairment of this cascade will result in temp...

Analysis of a large cohort of subjects with thyroid hemiagenesis (THA) reveals random seasonality in the dates of birth

Szczepanek-Parulska Ewelina , Zybek-Kocik Ariadna , Niedziela Marek , Czarnywojtek Agata , Ruchala Marek

Introduction: In the etiology of thyroid dysgenesis (TD) an interplay between genetic and environmental factors is thought to play a crucial role. Data from previous studies on association between the season of birth and the incidence of TD causing congenital hypothyroidism (mainly agenesis and ectopy) are conflicting. To date, seasonality of births have not been analysed yet in regard to congenital absence of one thyroid lobe (thyroid hemiagenesis, THA).<p class="abstext"...

The increased coexistence of autoimmune thyroiditis (AIT) in children and adolescents with thyroid carcinoma (TC) in years 2001–2015 compared to years 1996–2000

Introduction: In years 1996–2000, the predominance of papillary thyroid carcinoma (PTC) (70.3%) compared to follicular thyroid carcinoma (FTC; 27.0%) and medullary thyroid carcinoma (MTC; 2.7%) was observed in our region. AIT coexisted in 1 PTC (2.7% of all cancers and 3.8% in PTC group).Aim: The aim of retrospective study was to analyze the coexistence of AIT and TC in years 2001-2015 in relation to years 1996–2000.Mater...

Introduction: Combined pituitary hormone deficiency (CPHD) results in deficit of growth hormone and coexisting failure of synthesis or excretion at least another pituitary hormone. Transcription factors controlling expression of genes required for pituitary organogenesis are orchestrating entire development process and certain cell lineages differentiation, contributing therefore significantly to CPHD pathogenesis with childhood onset.Aims: The purpose o...

Introduction: Disorders of Sex Development (DSD) can be associated with an increased risk of germ cell tumours depending on the underlying diagnosis. To date however knowledge regarding the indications and timing of gonadectomy is lacking.Methods: The I-DSD Registry was interrogated for anonymised information regarding the diagnosis, karyotype, sex of rearing and timing of gonadectomy, if undertaken, of all individuals of any karyotype who were over the ...
