Introduction: Natural oestrogen administration as oral or transdermal 17β-estradiol is recommended for pubertal induction in girls with hypogonadism. However, suitable low-dose formulations are not consistently available globally. This questionnaire study aimed to identify the current availability of oestrogen and progesterone preparations worldwide.

Introduction: Turner Syndrome (TS) is the commonest chromosomal abnormality in females. Establishing and maintaining long-term follow-up after transition to adult endocrine services, to allow for essential lifelong surveillance of hypertension and cardiovascular disease, and optimal hormone replacement, remains a challenge. A TS transition clinic was established with the aim of supporting successful transfer and establishing long-term follow-up in adult endocrine services.

Article Synopsis
  • The study focused on the prevalence and risk factors of catch-up growth failure in term small for gestational age (SGA) infants.
  • A cohort of 457 SGA infants was tracked from birth to 2 years, revealing that while most showed normal growth, about 12% remained short at 24 months.
  • Factors like maternal height, growth metrics, SGA history, and breastfeeding duration were linked to ongoing growth issues, suggesting the need for tailored follow-up and possible treatment.

Article Synopsis
  • Paediatric endocrinology gained recognition in Western Europe during the 1960s and 1970s, but varies in presence across different countries, with some having established programs and others just starting out.
  • Human determination, mentorship, and the experience gained from fellowships abroad are crucial for developing successful pediatric endocrinology centers.
  • Effective networking through scientific societies and innovative training methods, like telemedicine, enhances knowledge sharing and fosters collaboration with adult endocrinology, benefiting patient care at multiple levels.

Article Synopsis
  • The European Society for Paediatric Endocrinology has expanded its interactive e-learning website since 2012, introducing comprehensive modules on pediatric diabetes and multilingual resources for healthcare providers in low-resource settings.
  • The platform offers various educational resources in areas like pediatrics, neonatology, clinical genetics, and pediatric gynecology, along with new formats like interactive video lectures and webinars for enhanced learning.
  • Recent recognition by the European Accreditation Council for Continuing Medical Education highlights the growing importance of digital education, especially during COVID-19, paving the way for future hybrid learning models that combine in-person and online education.

Background: 3β-hydroxysteroid dehydrogenase 2 (3βHSD2) deficiency is a rare form of congenital adrenal hyperplasia (CAH), with fewer than 200 cases reported in the world literature and few data on outcomes.

Patients And Methods: We report a mixed longitudinal and cross-sectional study from a single Algerian center between 2007 and 2021. Virilization and under-masculinization were assessed using Prader staging and the external masculinization score (EMS), pubertal development staged according to the system of Tanner.

Objective: Patients with thyrotoxicosis are treated with anti-thyroid drug (ATD) using block and replace (BR) or a smaller, titrated dose of ATD (dose titration, DT).

Design: A multi-centre, phase III, open-label trial of newly diagnosed paediatric thyrotoxicosis patients randomised to BR/DT. We compared the biochemical response to BR/DT in the first 6 months of therapy.

Background: Hypogonadism is a key feature of Prader-Willi syndrome (PWS) but clear strategies for hormone replacement are lacking.

Objective: To evaluate gonadal status and outcome in patients attending a Scottish PWS clinic from 1991-2019.

Methods: In 93 (35F:56M) patients, median follow-up 11.

Objective: Short stature in Turner syndrome (TS) may be accompanied by skeletal disproportion. This retrospective study investigates growth and disproportion from early childhood to adult height.

Study Design: Data were collected from 59 girls prior to growth hormone (rhGH) treatment and in 30 girls followed up longitudinally.

Article Synopsis
  • The study investigates the possible environmental factors influencing congenital hypothyroidism (CHT) due to thyroid dysgenesis (DG) in Scotland from 1979 to 2015, focusing on case clustering and changes in incidence over time.
  • Over 500 cases of CHT were analyzed, revealing an increasing incidence linked to methodology but no seasonal trends; significant clustering was found specifically in cases of DG, particularly among areas with lower birth densities.
  • The findings suggest a potential unidentified environmental factor affecting the development of thyroid DG, while no clustering was observed in cases of dyshormonogenesis (DHG).

Objective: To compare two methods of assessing gland size on thyroid ultrasound in newborn infants with suspected congenital hypothyroidism (CH).

Methods: Images from infants with eutopic glands referred between 2007 and 2013 were evaluated blind by two sets of observers. Subjective gland size was categorised as small, borderline-small, normal, borderline-large and large.

Objective: First-line treatment of thyrotoxicosis in young people is thionamide anti-thyroid drug (ATD) in a blocking dose with levothyroxine replacement (block and replace, BR) or in a smaller dose tailored to render the patient euthyroid (dose titration, DT). Our objective was to determine which regimen provides more stable biochemical control.

Design: A multi-centre phase III, open-label randomised trial comparing BR with DT in patients aged 2-17 years with newly diagnosed thyrotoxicosis at 15 UK centres.

Background: Hypopituitarism is a recognized sequela of traumatic brain injury (TBI) and may worsen the quality of life (QoL) in survivors.

Aims: To assess the prevalence of post-traumatic hypopituitarism (PTHP) and growth hormone deficiency (GHD), and determine their correlation with QoL.

Methods: Survivors of moderate to severe TBI were recruited from two Algerian centres.

Primary gonadal failure.

Best Pract Res Clin Endocrinol Metab

June 2019

The term primary gonadal failure encompasses not only testicular insufficiency in 46,XY males and ovarian insufficiency in 46,XX females, but also those disorders of sex development (DSD) which result in gender assignment that is at variance with the genotype and gonadal type. In boys, causes of gonadal failure include Klinefelter and other aneuploidy syndromes, bilateral cryptorchidism, testicular torsion, and forms of 46,XY DSD such as partial androgen insensitivity. Causes in girls include Turner syndrome and other aneuploidies, galactosemia, and autoimmune ovarian failure.

Background: Most girls with Turner syndrome (TS) require pubertal induction with estrogen, followed by long term replacement. However, no adequately powered prospective studies comparing transdermal with oral 17β-estradiol administration exist. This reflects the difficulty of securing funding to study a rare condition with relatively low morbidity/mortality when competing against conditions such as cancer and vascular disease.
