Background: Precocious puberty, pubertal development in girls before 8 years, has considerable biological, psychosocial, and long-term health implications. It is classically ascribed to the premature activation of the hypothalamic-pituitary–gonadal axis, and hence an LH response >5 U/l in the LHRH test. Whilst this group of patients is well understood, there is a paucity of literature characterising patients who show pubertal development not driven by LH, atypical pre...

Background: Management of SIADH is challenging and no optimal therapies are available in children. We present a case of an 11 years old boy with severe SIADH resistant to 30% fluid restriction in the context of an intracranial suprasellar high grade B-cell lymphoma who requires hyperhydration for chemotherapy protocol. Tolvaptan is an oral highly selective arginine vasopressin V2 receptor antagonist, which has been approved for use in SIADH in adults.Obj...

Background: Polycystic ovary syndrome (PCOS) continues to be a diagnostic challenge in adolescent girls. Symptoms like oligomenorrhea and acne, and polycystic ovarian morphology on ultrasound can be normal variants in adolescents. In addition to diagnostic difficulties, there is lack of randomized controlled trials for PCOS treatments specific to adolescents. Current guidelines for diagnosis and management of PCOS in adolescents have large variations and rely ...

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: Pubertal growth and adult height are important to many transgender adolescents undergoing medical transition. However, few studies are available on the impact of puberty suppression (PS) with GnRH analogues (GnRHa) and hormonal therapy (HT) with testosterone on growth. In this longitudinal cohort study, we investigated the effect of PS and HT on growth and adult height in transgender boys.Methods: A total of ...

Background: Gonadotropin-releasing hormone agonists (GnRHa) are common treatment in adolescents with gender dysphoria to prevent development of unwanted physical changes. However, the safe use of GnRHa is debated in the media and objective literature is sparse. Specifically, there is a lack of literature comparing between different Tanner stadia, since it is debatable whether GnRHa treatment is effective in adolescents who have almost gone through puberty (Tan...

Background: The goal of treatment in children with hypophosphatemic rickets (HR) attempts to correct growth and leg deformities. However, growth is compromised despite treatment and patients are at risk of developing nephrocalcinosis in the future. Some factors (sex, age and height at diagnosis) have been related to height outcome, but little is known about the impact in growth of different dosage of treatment or alkaline phosphatase (ALP) levels.Objecti...

Introduction: Worldwide the Short Synacthen Test (SST) is the most popular diagnostic investigation for adrenal insufficiency (AI) amongst both paediatric and adult endocrinologists. Cannulation and blood sampling are required making it invasive, time-consuming and resource-intensive. We have previously validated a reliably absorbed and well tolerated formulation of nasal synacthen (Nasacthin003) in healthy adult males, measuring the glucocorticoid response in salivary cortiso...

Introduction: Recombinant GH is an effective treatment for short children who are born small for gestational age(SGA). Short children SGA who fail catch-up growth by 4 years of age are candidates for GH treatment, at a dose of 35–70 μg/kg per day. Factors associated with response to GH treatment during the initial 2–3 years of therapy include age and height standard deviation scores at the start of therapy, midparental height, and GH dose. It is important to kno...

Background: Excessive energy intake and rapid weight gain early in life are associated with obesity, type 2 diabetes, hepatic steatosis and other features of the metabolic syndrome. The monoacylglycerol acyltransferase (MGAT) is an enzyme involved in an alternative pathway for triglyceride (TAG) synthesis and storage. It has been recently proposed to have potential implications in the pathogenesis of hepatic insulin resistance (IR).Objective: To understa...
