Introduction: The outcome of hypospadias is considered to be primarily dependent on the underlying aetiology, its surgical management and the duration of follow-up. However, currently, there is little consensus on what set of parameters are essential and clinically feasible for assessment of outcome.Aim: To facilitate the development of a core outcome set for hypospadias by assessment of the range of outcomes reported in boys undergoing surgery.<p cl...

Background: Complication rates following hypospadias surgery are variable and given that hypospadias may be associated with a genetic or an endocrine condition, hypospadias outcome may depend on several clinical factors that require exploration.Aim: To perform a systematic review of cases of hypospadias operated at one tertiary centre to identify clinical determinants of optimal outcome.Methods: Retrospective review of clinical rec...

Background: Hypospadias in boys may be associated with a lack of androgen exposure during the masculinisation programming window. As testosterone has effects on the vasculature, we assessed whether boys with hypospadias show any evidence of vascular dysfunction.Methods: Excess foreskin tissue was obtained from boys undergoing hypospadias repair (cases) or circumcision (controls) and small arteries dissected from this tissue. Vascular contractility was as...

Background: Multiple endocrine neoplasia type 2B (MEN 2B) is a rare endocrine disease associated with early and aggressive medullary thyroid carcinoma (MTC), pheochromocytoma and several non-endocrine manifestations. MEN 2B is often diagnosed late, when symptomatic thyroid disease is present. Recognition of early, often non-endocrine, manifestations is elemental and may lead to early intervention through early diagnosis. However, early recognition is complicated by both the br...

Background: Testotoxicosis or familial male-limited precocious puberty (FMPP) is a rare disease caused by an autosomal dominant activating mutation of the luteinizing hormone receptor gene, leading to early gonadotrophin-independent precocious puberty. Phenotypic expression is limited to males. Treatment evolved over the last decades and nowadays consists of a combination of a potent anti-androgen agent and a third-generation aromatase inhibitor. Since the identification of et...

Background: Persistent severe insulin resistance (IR) in T1DM is infrequent, complex to handle and disabling. Genetic and epigenetic factors play a significant role in the pathophysiology of IR. This case report discusses the potential role of habitual and stress-inducing environmental factors in a school-aged boy with a neurodevelopmental disorder.Case report: We present an eight year old boy with a three year history of T1DM (GAD positive) regulated by...

Background: A decrease in random LH concentration is observed after initiation of treatment for central precocious puberty (CPP), but the suitability of random LH concentrations for assessing efficacy is controversial. Although Neely et al. reported that random LH values frequently fail to demonstrate suppression to prepubertal levels,1 Lee et al. demonstrated that a cutoff of random LH <0.6 IU/l may be adequate for monitoring s...

Background: There is evidence that unstimulated LH concentrations may be appropriate to monitor hormone suppression in children with central precocious puberty (CPP) during treatment with gonadotropin-releasing hormone agonists (GnRHa). Literature suggests that unstimulated LH concentrations <0.3 and >0.8 IU/L are prepubertal and clearly pubertal, respectively. We present secondary analyses of unstimulated LH suppression data from the pivotal trial of th...

Introduction: Achieving/maintaining effective hormone suppression is fundamental in treating Central Precocious Puberty(CPP). CPP patients are vulnerable to late dosing as they cannot self-administer and require clinic/hospital visits for injections, currently exacerbated by COVID-19. In children, the hypothalamic-pituitary-gonadal axis may rebound faster than elderly oncology patients, so hormone escapes are possible with late dosing. Additionally, the stimul...

Introduction: The external masculinisation score (EMS) has been utilised as an objective numerical description of the external genitalia in undermasculinised patients with DSD in several studies. However, data on longitudinal change in EMS in the routine clinical setting are lacking.Objectives: To determine the longitudinal change in EMS and its determinants in a cohort of boys with XY DSD in one specialist centre.<p...
