The Influences of Circulating Leptin, Kisspeptin, and Neurokinin B Levels to Precocious Puberty in Obese Girls

Kang Min Jae , Kim Eun Young , Oh Yeon Joung , Baek Joon Woo , Yang Seung , Hwang Il Tae

Background: Leptin has a major role in the metabolic gating of pubertal maturation. Kisspeptin is an essential gatekeeper of puberty. Neurokinin B (NK B) is not widely known in the precocious puberty (PP) but it is coexpressed with kisspeptin in the arcuate nucleus and synchronizes the pulsatile secretion of kisspeptin.Objective and hypotheses: Leptin, kisspeptin, and NK B are influenced by energy balance and metabolic status has a clear impact on the ti...

An Unusual Case of Growth Hormone Replacement Therapy in a Child with Hereditary Multiple Exostoses and Growth Hormone Deficiency

Xatzipsalti Maria , Polychroni Ioulia , Fryssira Elena , Stamoyannou Lela

Background: Hereditary multiple exostoses (HME) is an autosomal dominant heritable disorder characterized by exostoses located mainly in the long bones of extremities. HME is caused by mutations in two genes: EXT1, EXT2.Objective and hypotheses: Growth hormone (GH) deficiency is very rare in children with HME and GH replacement therapy has not been well described.Method: A 12.5 years old girl was referred to our Department because ...

An Unusual Presentation of Hashimoto Thyroiditis (HT) and Precocious Puberty: The Van Wyk-Grumbach Syndrome

Leka-Emiri Sofia , Karachaliou Feneli , Fotinou Aspasia , Petrou Vassilis , Michalakos Stefanos

Background: The association of primary hypothyroidism and isosexual precocious pseudopuberty in females was first described in 1960 by Van Wyk and Grumbach. The unique elements that lead to the diagnosis are FSH-dominated sexual precocity with non advanced bone age in the presence of hypothyroidism.Objective and methods: Describe an 8.5 years old girl with hypothyroidism due to HT and clinical and hormonal features of Van-Wyk and Grumbach syndrome.<p...

Background: The relationship of obesity and emotional disorders is confirmed in many studies. It is known that one of the substances responsible for the emotional status is dopamine.Objective: To study the features of neuroendocrine status in obese children.Methods: We examined 285 children (206 obese, age 14.56±2 years, BMI 32.86±5.1 kg/m2; 79 normal weight (control), 14.51±2.2 years (P=0.95), 19...

High-Dose Hook Effect in 17- Hydroxyprogesterone Assay in 21-Hydroxylase Deficiency

Parlak Mesut , Turkkahraman Doga , Parlak Ayse Eda , Ellidag Hamit Yasar

Background: False-negative results can occur an extremely high level of substrate at the assay system. This is called the ‘high-dose hook effect’.Case presentation: 14 year-old female patient was referred with short stature, amenorea and hirsutism. Height, weight and blood pressure were 140.5 cm (SDS:−3.5), 43.4 kg (SDS:−1.6) and 120/80 mmHg. She had stage 1 Tanner breast, stage 5 pubic hair and hirsutism (mFG scale: 28) with androi...

Estimation of Adipsin, Omentin and Vaspin Concentration in Prepubertal Children with GH Deficiency before and after 6 Months of GH Treatment

Rudzka-Kocjan Agnieszka , Szalecki Mieczyslaw

Background: GH deficiency (GHD) is usually associated with excess of abdominal fat tissue and increased risk of developing cardiovascular diseases. Adipose tissue produces different adipocytokines that could explain the relationship between excess of fat tissue and increased metabolic risk. Adipsin, omentin and vaspin are adipocytokines which are still not well examined.Objective and hypotheses: To estimate the effect of 6 months GH therapy on serum conc...

Effects of seasonal variability of insolation and COVID-19 pandemic isolation on vitamin D concentrations in children

Smyczyńska Joanna , Hilczer Maciej , Łupińska Anna , Pawelak Natalia , Lewiński Andrzej , Stawerska Renata

Introduction: Vitamin D may be considered as a hormone of prohormone of pleiotropic effects. Seasonal variability of insolation affects its synthesis in humans. In our latitude, vitamin D deficiency is widespread. In 2018, updated recommendations for vitamin D supplementation were published in Poland by Rusi&nacute;ska et al. In 2020, SARS-CoV-2 pandemic lockdown was introduced, with suggestions of protective anti-viral vitamin D role.<p class="ab...

Neonatal CAH screening in patients with rare causes of inherited primary adrenal insufficiency

Kurt Ilknur , Eser Metin , Kahveci Ahmet , Ucar Ahmet , Bulus Derya , Ozcabi Bahar , Guran Tulay

Background and objective: 21alpha-hydroxylase deficiency congenital adrenal hyperplasia (21OHD-CAH) is the most common etiology of inherited primary adrenal insufficiency (PAI) in children. Neonatal CAH screening is important for early diagnosis of salt-wasting 21OHD and other virilizing CAH (11beta-hydroxylase, 3beta-hydroxysteroid dehydrogenase deficiencies) and for avoiding mortality, especially in salt-wasting CAH. Neonatal CAH screening has become nationw...

Introduction-Purpose: In addition to chromosomal abnormalities, a number of genes have been implicated as causes of Disorders of Sexual Development (DSD). The NR5A1 (SF-1) gene expresses a transcription factor that plays a role in steroidogenesis by controlling multiple stages of adrenal and gonadal development, and its mutations have been reported in cases of DSD.Case presentation: A 152/12-year-old teenager ...
