Background: The thyroid gland is a common unintended target during and after cancer treatment in childhood cancer survivors. However, only a limited number of studies have assessed thyroid adverse events of newer or more selective anticancer drugs. The main objectives of this review are to provide an overview of thyroid disorders in children, treated with 131 I-metaiodobenzylguanidine (131 I-MIBG), tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibi...

Background: Paragangliomas are rare tumours that originate from neural crest cells. Diagnosing and managing patients with paragangliomas pose several challenges.Objective: We investigated whether MECP2 defects are associated with an idiopathic CPP phenotype with or without mild neurodevelopmental abnormalities.Clinical presentation: A 14-year-old female presented with cons...

A 7 year old girl presented with breast development, mood changes and rapid growth spurt from 6.5 years. Clinically she was tall for her family and had Tanner stage 2 breast development and pubic hair. Bone age was 3 years advanced and pelvic ultrasound demonstrated globular anteverted uterus with endometrial lining and enlargement of the ovaries with follicles. LHRH test confirmed central precocious puberty with peak LH 44mIU/ml and FSH 19mIU/ml, with baseline estradiol of 92...

Background: Severe primary insulin-like growth factor-1 deficiency (SPIGFD) is a rare growth disorder characterised by severe short stature. Replacement therapy with recombinant human IGF-1 (rhIGF-1; mecasermin [Increlex®]) is currently the only available treatment for children/adolescents with SPIGFD. We describe the methodology of the Global Increlex Patient Registry (NCT00903110), designed to monitor long-term safety and effectiveness of meca...

Background: Overweight as a predictor of adverse cardiovascular outcome is of particular interest in gender-affirming healthcare. Transgender populations are at a higher risk for obesity, possibly due to a combination of minority stress, psychiatric comorbidity, and lifestyle differences, such as reluctance to participate in group sports as a consequence of social withdrawal. However, robust auxological data in transgender adolescents is scarce.<p class="a...

Background: 17a-hydroxylase/17,20-lyase deficiency is a rare cause of congenital adrenal hyperplasia (CAH). 46,XY infants may present with ambiguous genitalia. Adrenal crises are rare due to compensatory glucocorticoid action of the overproduced corticosterone.Case: A 3-month-old boy underwent a complication-free externalization of concealed penis and circumcision by a paediatric surgeon. At the age of 2.5 years, the boy...

Background: Sickle cell anemia (SCA) leads to chronic end organ damage including the thyroid gland. This is postulated to be due to recurrent hemolysis leading to iron overload, vaso-occlusive crises, micro-vasculature obstruction due to red cell entrapment and frequent transfusions. Some studies have demonstrated a relationship between hypothyroidism and SCA with a prevalence of 6% in children and adolescents. Hypothyroidism may affect brain and physical deve...

Backround: Menstrual disorders are common among the adolescent girls. We examined the initial investigations performed in adolescents, presenting with frequent, heavy or painful periods. Although, usually abnormal uterine bleeding (AUB) in adolescent women is attributable to immaturity of the hypothalamic-pituitary-ovarian axis, underlying conditions such as coagulation disorders and anemia should always kept in mind. However, neither the laboratory nor the ultrasound investig...

Background: In children with Prader–Willi Syndrome (PWS), hypothalamic dysfunction plays a key role in the development of aberrant energy regulation, sleep-related breathing disorders, hypogonadism and impaired linear growth. Dysfunction of the hypothalamic–pituitary–adrenal (HPA) axis may contribute to the high incidence of sudden death. The prevalence and the extent of the dysfunction of HPA axis remain unclear.Method: Thirty-one (10M/21...

Background: Vitamin-D deficiency becomes a worldwide issue, and major cause of rickets in younger age groups. Multiple causes lead to vitamin-D deficiency in which nutritional causes contribute the major factor. The synthesis of bioactive vitamin-D requires hydroxylation at 1α and 25 positions by cytochrome-P450 in the kidney and liver, respectively. Recently, human CYP2R1 has been reported as a major factor for 25-hydroxylation, in which it contributes for the inherited ...
