Background: The hypothalamic–pituitary–adrenal (HPA) axis responds to several acute or chronic environmental stessors, including those of social stress.Objective and hypotheses: To assess the HPA axis acute response during mental stress and mobile phone call exposure in healthy adolescents through salivary cortisol measurements and to investigate the modulatory effect of baseline biochemical or low-inflammation markers during this response....

Background: Insulin resistance occurs in a variety of common endocrine disorders including obesity, type 2 diabetes, polycystic ovarian syndrome, and metabolic syndrome. Additionally, rare syndromes exist that result in extreme insulin resistance. These conditions help contribute to our knowledge of the mechanisms of insulin signalling and resistance.Objective and hypotheses: We report a case of a 12 year old female presenting to endocrinology clinic for...

Background: Cystic fibrosis-related diabetes (CFRD) is the most common co-morbidity in association with cystic fibrosis. Cystic fibrosis related diabetes is predominantly an insulin deficiency state it shares features of both type 1 and type 2 diabetes, yet there are important differences, which necessitate a unique approach to diagnosis and management. Development of cystic fibrosis related diabetes is associated with a worse lung function, poorer nutritional status, and more...

Background: Hypothalamic obesity (HyOb) is a rare form of treatment-resistant morbid obesity associated with congenital or acquired hypothalamic damage. Its pathophysiology has been attributed to hyperphagia and hyperinsulinaemia. The wider roles of oxytocin (OXT) in regulating appetite and weight have recently emerged in animal and human studies, but there is no human evidence that hypo-oxytocinaemia contributes to weight gain.Hypothesis: Hypo-oxytocina...

Background: Evidence of the association between vitamin D, insulin resistance and oral disposition index (oDI) in obese children and adolescents is limited.Objective and hypotheses: We investigated serum 25(OH)D levels in obese children and adolescents in Zhejiang, China, and determined the relationship between serum 25(OH)D and glucose metabolism.Method: A cross-sectional design was used. All together 348 obese and 445 non-obese c...

Background: The majority of Turner syndrome (TS) girls need exogenous estrogen treatment to induce normal uterine growth. The optimal estrogen treatment protocol has not been determined.Objective and hypotheses: To compare the effect of two different dosing regimens of oral 17β-estradiol on uterine size with the hypotheses that most girls with TS would benefit from a higher dose.Method: A double-blind 5-year randomized control...

Background: Ovarian and uterine development in relation to hormonal feedback mechanisms (E2, LH, FSH, and inhibin) has rarely been studied. Therefore, the age specific and longitudinally adequate replacement dose of estradiol to achieve normal maturation in terms of ovarian and uterine development during infancy, childhood and adolescence remains not well known. However, aromatase deficiency offers an excellent model to study the relevant estradiol dose needed to ac...

Background: Obesity is a major risk factor for developing type 2 diabetes mellitus (T2DM). Despite the obesity epidemics, the incidence of childhood T2DM is not increased.Objective and hypotheses: To assess the β-cell reserve expressed as an oral glucose disposition index (GDIo), an independent predictor of developing T2DM.Method: A total of 80 adolescents (61.3% girls), aged from 10.0 to 17.6 years (mean age 13.59±2.34 y...

Background: Unlike to adults, the side effects of long-term administration by amiodarone (A) of life-threatening arrhythmias (LThA) on thyroid function still is not studied exactly in children.Methods: Twenty-six children with LThA aged 1 week to 16 years (mean 10 years) treated by A were examined. The mean duration of oral treatment ranged from 1 month to 47 months (mean 12.5 months). We estimated serum level of T4, T3, TSH, antibo...

Background: Cushing syndrome is very rare in childhood and adolescence and often occurs with iatrogenic causes. The major cause of endogenous Cushing syndrome is Cushing’s disease, which results due to excessive ACTH secretion from pituitary cells (corticotroph adenoma).Objective and hypothesis: Cushing syndrome cases, which presented with diabetic ketoacidosis (DKA) in adulthood have been rarely reported. However, to our knowledge, there is no repo...
