Background: Many children with type 1 diabetes (T1D) are asked to measure blood glucose (BG) 4–6 times a day routinely to adjust insulin dosages. There is no evidence though that such high frequency is beneficial to HbA1C or glycemic profile, although this is often claimed.Objectives: We challenged ‘the more BG measurements, the better control’ dogma for alleviation of T1D burden in child life and evaluation of HbA1C.<p class="abstext"...

A 13 months old infant, presented with failure to thrive, untreated congenital hypothyroidism and pseudo-hypertrophy of limb muscles (i.e. Kocher-Debre-Semelaigne syndrome). The child had delayed motor and mental development. Thyroxin replacement therapy, as well as nutritional support, was initiated.Two to three weeks after treatment introduction, the motor and cognitive developments were accelerated with striking improvement as if global growth was sto...

Background: Vitamin D Dependent Rickets Type IA(VDDR1a) is an autosomal recessive disorder characterized by defects in the biosynthesis of its active form 1,25 dihydroxyvitamin D due to the mutations in the CYP27B1 gene encoding for the enzyme 1α-hydroxylase.Objective and hypotheses: To evaluatethe clinical characteristics, molecular genetics aetiology and long-term outcome of a large nationwide cohort of VDDR-Ia f...

An 11-year-old female presents with a 6-week history of double and blurred vision associated with headaches and neck swelling. Thyroid function tests demonstrated antibody negative hypothyroidism and connective tissue disorder screening was negative. The patient was commenced on thyroid hormone replacement (levothyroxine). 5 days later, she re-presented with strabismus and progressive diplopia. Intracranial imaging was performed to rule out space occupying masses. A diagnosis ...

Background: The need to understand the relationship between bone, muscle, and fat within the bone-muscle unit has recently gained great prominence. Although high resolution (HR) MRI is a non-invasive imaging modality that can provide this information, there is limited expertise in children and young people.Objectives: To establish MRI-based normative data for bone, bone marrow adiposity and muscle adiposity in children a...

Background: Cis-gender females are known to mount stronger immune responses to invading pathogens or vaccines than cis-gender males. However, this is also associated with increased risk of autoimmunity. Little is known about the immunophenotypes of transgender individuals on gender-affirming hormonal treatment, despite growing evidence that hormones influence the immune system. Via the process of class-switch recombination (CSR), B-cell immunoglobulin isotype ...

Background: Identification of Congenital Hypothyroidism (CH) is an essential part of Newborn Bloodspot Screening (NBS) in the UK. NBS for CH relies on Blood Spot (BS) Thyroid Stimulating Hormone (TSH) measurement in newborns on day 5 of life. Diagnostic confirmation of a screen positive result requires measurement of plasma/serum free thyroxine (fT4) and TSH but technetium thyroid scanning is not mandatory. Technetium-99m scintigraphy can be used to define siz...

Background: To the best of our knowledge, no study has been conducted to assess the impact of 21 hydroxylase deficiency and hidrocortisone treatment on electrocardiographic measures in children with 21-hydroxylase-deficient congenital adrenal hyperplasia.Objective and hypotheses: The purpose of this study is to compare the12-lead electrocardiographic measures such as PWd, QT interval, QTd, Tp-e interval, Tp-e/QT and Tp-e/QTc ratio in patients of 21-hydro...

Objective: To evaluate musculoskeletal development using pQCT in children with coeliac disease (CD) on gluten free diet (GFD) compared with age and gender matched healthy controls.Method: Prospective cross sectional study. 38 children (18 males) with CD on GFD for a duration of 3.6 years (0.6, 12.5) and 38 age and sex matched healthy controls underwent pQCT at 4, 38 and 66% tibial sites. Bloods were collected in CD children only. Results reported as medi...

Background: Recent work revealed two pathways in androgen biosynthesis, namely the classic and an alternative, the backdoor pathway. In this alternative pathway dihydrotestosterone is produced from 17-hydroxyprogesterone without the intermediacy of testosterone using mostly enzymes that are specific to the backdoor path. In the human ovary, regulation of androgen production plays a crucial role in normal physiology and in pathologies such as the polycystic ovary syndrome (PCOS...
