Aim: To determine the sensitivity, specificity of basal LH measurement compared to the GnRH test in patients with Central precocious puberty (CPP) and determine the cut off point for basal LH to diagnose CPP.Methods: 680 female patients were referred for presumptive diagnosis of central precocious puberty in the city of Bogota. All patients went through a GnRH test, using a Roche immunoassay for Luteinizing hormone (LH) and follicle stimulating hormone (...

Background: The majority of drug developments in type 1 diabetes (T1D) are aimed at preventing decline of beta cell function (BCF), as this has been associated with better glycaemic control and fewer long-term complications. Traditionally, BCF is evaluated by the C-peptide response to the labour-intensive mixed-meal-tolerance-test (MMTT), but there’s a need for a more practical alternative. We developed a new method to measure C-peptide in ‘dried blood spots’ (D...

Background: Polycystic ovarian syndrome (PCOS) diagnosis includes ovarian morphology using transvaginal ultrasound (US). However transvaginal US cannot be used in virginal girls and transabdominal US is not optimal particularly in obese patients.Objective and hypotheses: To evaluate the validity and reproducibility of ovarian morphology measures using MRI for the diagnosis of PCOS in adolescents.Method: This case-control study (200...

Background: 46,XY patients with SF-1 mutations have sex reversal or ambiguous genitalia (with or adrenal insufficiency) due to dysgenetic testis. In most cases, a severe defect in testosterone (T) production has been found. We described here 3 cases showing the variability in T production.Results: Case 1: A was seen at the age of 17 years for primary amenorrhea. Tanner stage was B2PH3. External genitalia were normal. FSH was 55 IU/l, LH 17 IU/l,...

Background: A significant component of total linear growth is height gain achieved after the initiation of puberty. Children with Isolated GH Deficiency (IGHD) frequently come for evaluation around the peripubertal stage. Therefore, increasing pubertal height gain in IGHD children entering puberty with a relatively low height is important. Researchers have tried to assess effectiveness of treatment in such patients based on various key measurements and a variety of end-points....

Background: Thyroid hormones are essential in the regulation of foetal and post-natal neurodevelopment. Despite early diagnosis and treatment of congenital hypothyroidism (CH) difficulties with language, hearing, memory and motor function persist for some children. However, comprehensive data about hearing, language and communication function in children with CH are not widely available.Objective and hypotheses: To evaluate hearing, language and communic...

Background: Dietary and lifestyle modifications commonly proposed to overweight or obese youth lack efficacy in those with severe obesity. Early results with bariatric procedures in obese adolescents suggest that weight loss and safety are comparable or better than those seen in adults. One of these procedures, laparoscopic sleeve gastrectomy, is commonly performed using multiple ports. We selected single port sleeve gastrectomy (SPSG) as a minimally invasive surgery to be tes...

Background: After 50 years of hGH use for GH deficient (GHD) children the definition of the adequate hGH substitution dose and response remain uncertain.Objective and hypotheses: We hypothesized that subjects with GHD caused by congenital pituitary defects constitute an ideal model for defining substitution dose of hGH. Consequently, an appropriate study group was formed and pertinent long-term data were retrospectively analyzed.Me...

Background: Hypothalamic hamartomas (HH) are congenital morphogenetic defects frequently associated with central precocious puberty (CPP).Objective and hypotheses: Data on the outcome of girls with CPP due to HH are limited.Method: We report two patients with CPP caused by HH, one with normal fertility.Results: Patient 1, now aged 33 years, was examined at age 15 months (vaginal bleeding, breast and pubic hai...

Background: Congenital adrenal hyperplasia (CAH) is a rare chronic disease diagnosed and treated from birth. Hormone replacement therapy is essential to lead a normal life and must be adapted to stress. Poor compliance to treatment or inefficacy is life threatening leading to high risk of by dehydration and hypoglycaemia.Objective: The objective of therapeutic education sessions is based on the skills needed for regular intake of pills and recognition of...
