Background: Measuring testicular volume (TV) by orchidometer is a standard method of pubertal staging in boys. A paucity of evidence exists as to its inter and intra-user reliability and the impact of clinicians’ gender, training and experience on the accuracy of measurements.Objective and hypotheses: We engineered prosthetic models of different size testes to investigate the reliability of TV estimation.Method: The study was ...

Introduction: Conventional treatment of X-linked hypophosphataemic rickets (XLH) involves administration of oral phosphate and vitamin D analogues. An important treatment goal is to heal rickets which is assessed by normalisation of serum alkaline phosphatase (ALP) levels and resolution of radiological signs of rickets.Objectives: To determine the usefulness of serum ALP in assessing disease severity on wrist and knee ra...

Introduction: 46, XY DSD leave lifelong implications on parents and patients. Documented scientific literature on children with 46, XY DSD is scares in Sri Lanka. This study assesses the psychosocial wellbeing of parents and the quality of life in children with 46 XY DSD.Objective: To assess the psychosocial wellbeing of parents and the quality of life in children with 46, XY DSD attending the endocrine clinics at Lady R...

Introduction: Anti-obesity drugs with increased efficacy and safety are urgently being sought. Peptide YY3–36 (PYY3–36) is an attractive drug target due to its anorectic effect and decreased circulation concentration, without drug resistance, in obese individuals. Its short half-life and required method of delivery are limiting factors in its clinical application. Transport and uptake mechanisms, including blood-brain barrier passage, of vitamin B12 (B12) is highly e...

Background: Familial Hypercholesterolaemia (FH) is a common autosomal dominant disorder of low-density lipoprotein (LDL) metabolism characterised by elevated levels of plasma LDL-cholesterol (LDL-C), accelerated atherosclerosis and premature cardiovascular disease (CVD). In the Gulf Co-operation Council states, CVD is often diagnosed at a younger age and is the leading cause of mortality. As such, early genetic diagnosis and treatment of FH is important for ri...

Background: The majority of children diagnosed with idiopathic isolated growth hormone deficiency (IIGHD) show a normal growth hormone (GH) secretion (assessed by GH stimulation tests) when retested at near adult height (NAH). It appears plausible that if normal stimulated GH secretion is observed in mid-puberty, continuing recombinant human GH (rhGH) treatment may only have a minor effect on NAH. The effect on NAH has never been investigated in a prospective ...

Neonatal screening tests are used for the screening of genetic, endocrine and metabolic diseases. Preterm newborns have a higher false-positive and false-negative results in neonatal screening. The objective of this study was to estimate the prevalence of false-positive and false-negative results in the neonatal screening tests for phenylketonuria, congenital hypothyroidism, biotinidase deficiency and congenital adrenal hyperplasia (CAH) in preterm newborns in Curitiba, to ana...

Background: A portion of 160 kb on Xp21.2 is defined as dosage sensitive sex reversal, including NR0B1, which is considered the most likely candidate gene involved in XY gonadal dysgenesis if overexpressed. The excess of NR0B1 gene product seems to disturb testicular development by down regulating NR5A1, WT1, and SOX9. Xp duplication causes insufficient SRY expression leading to testis development failure. However, NR0B1 si...

Introduction: Generally, patients with X-linked hypophosphatemic rickets (XLH) experience normal puberty. However, they can be affected by metabolic and environmental factors that may predispose them to central precocious puberty (CPP) and impair their predicted final height, similar to the general population.Case Report: A female patient was diagnosed with XLH at three and received regular treatment with calcitriol and ...

Burosumab, a monoclonal antibody targeting fibroblast growth factor 23, is now available for clinical use in children with X-linked hypophosphatemia (XLH). We explored the effects of this treatment in a clinical setting, considering biochemistry, growth, deformity, functionality, quality of life, pain and fatigue.Methods: Clinical, biochemical, radiological and questionnaire data were reviewed at 6 and 12 months in a cohort of 8 children...
