Summary Answer: Most primordial/primary oocytes were found to have a 46,XX karyotype. Chromosome patterns of the ovarian cells were different from that observed in other tissues.Background: TS is a chromosomal condition associated with partial or complete absence of one of the two X-chromosomes. Females with TS have a limited reproductive lifespan due to an accelerated loss of germ cells. It has been hypothesized that vi...

Background: Silver Russell syndrome (SRS) is characterized by low birth weight, severe postnatal short stature and distinctive facies. In ~50% of patients, (epi)genetic alterations can be detected (~40% hypomethylation of H19 on chromosome 11, ~10% maternal uniparental disomy (UPD) 7). As SRS patients are usually born small for gestational age (SGA), they are treated with GH to improve height. However, data on long-term effects of GH treatment in SRS patients are very limited....

Introduction: X-linked hypophosphataemic rickets (XLH), due to mutations in the PHEX (Phosphate-regulating Endopeptidase homolog; X-linked) gene, causes reduced bone and dentin mineralisation and decreased renal phosphate reabsorption. Mosaic PHEX mutations are reported only in a few case reports.We report three male cases, with mosaic pathogenic PHEX variants, showing importance of considering this in the diagnosis of XLH.Case 1 pre...

Introduction: Hydrocortisone (HC) has a short half-life and individualization of treatment is required for optimal treatment of CAH, balancing between under- and overtreatment. Twenty four hour profiling of HC concentrations has shown large interindividual variation in clearance of HC and therefore has been used to individualize treatment. We present a severely virialized girl with CAH, in whom high doses of steroids failed to suppress androgen production thou...

Abnormal phenotypes in patients with ring chromosome X can be ascribed to failed or partial X inactivation due to loss of XIST on Xq13. We describe a mother and 1 daughter with the same mosaic karyotype, and another daughter with 45, X. KZ, 12 years old and recently moved from Poland, was investigated for short stature (Ht SDS -2.1), her mother was 142.9 cm, father 176.1cm. Both were healthy and not dysmorphic. Birth weight at 37 weeks was 2.63kg (20th centile Polis...

Introduction: Establishing a clear diagnosis in patients with short stature can be challenging. Careful examination and investigation of patients with short stature may identify additional features that help to make a diagnosis or direct genetic testing. We describe a patient with severe short stature with additional features on examination suggestive of KBG syndrome. A subsequent skeletal survey revealed radiological features suggestive of the diagnosis. In a...

Background: A substantially reduced fluid replacement regimen was introduced in the ‘New’ British Society of Paediatric Endocrinology Diabetes (2015) compared to ‘Old’(2009) guideline for DKA management. However, data on varying fluid replacement regimens is limited and we explored this by comparing outcomes of the 2 guidelines on the resolution of DKA.Methods: In a retrospective audit of consecutively admitted patients (age <18 y...

Background: Neonatal diabetes can present from birth to six months of age. This can often be confused with sepsis as there is considerable overlap of symptoms in this age group as illustrated below.Objective and hypotheses: The cases described illustrate the importance of blood glucose monitoring in sick infants presenting to emergency care settings we recommend an initial check of blood glucose concentrations in all sick infants who present to Accident ...

Background: The COVID-19 pandemic has resulted in rapid implementation of tele-clinics; patients have frequently missed routine point-of-care HbA1c testing, vital for evaluating long-term glycaemic control. We evaluated the feasibility of remote HbA1c monitoring via self-collection of capillary blood samples at home, and examined clinical characteristics associated with engagement with this system.Methods: Bio-Rad Haemog...

Objectives: The SARS-CoV-2 pandemic has resulted in major cutbacks in service provision to patients. This could be detrimental to children with diabetes mellitus (DM), whose condition could deteriorate from poor access to healthcare. The lockdown has also potentially caused changes in diet, sedentary behavior and psychological burden due to the stress associated with the pandemic, which can have negative effects on glycemic control. Thus, this study compares c...
