Background: Turner syndrome (TS) arises from a complete or partial loss of one X chromosome (45,X) and is the most common genetic cause of primary ovarian insufficiency (POI) in women. Surprisingly little is understood about the pathogenesis of POI in TS beyond an acknowledged germ cell loss throughout the second trimester. Although X chromosome haploinsufficiency likely contributes, the variability in reproductive phenotype in 45,X TS suggests it is not the o...

Background and aims: Achieving good glycemic control is a major challenge for adolescents with type 1 diabetes (TID). The introduction of the MiniMed 780G system, an advanced hybrid closed-loop (AHCL), that enables an automatic correction of insulin, gave hope for improved glycemic outcomes in adolescents. We assessed specific characteristics associated with glycemic measures in youth with T1D switching to Minimed 780G.Methods:</...

Objectives: To assess the long-term effect of growth hormone (GH) therapy in children with Turner Syndrome (TS)Patients and methods: We evaluated retrospectively the anthropometric data of 10 girls with TS short children (height SDS <-2) who were diagnosed and treated with GH (0.05 mg/kg/day) between January 2007 till 2018 in our tertiary care center. Before and during GH treatment, auxological and biochemical parameters including He...

Background: Hypospadias is a common characteristic of Disorders of Sex Development (DSD). At the present time a molecular diagnosis is not reached in over 50% of cases. The DDD Study represents a useful resource of large molecular and phenotypic datasets obtained from individuals with an undiagnosed developmental abnormality including DSD.Objective: To review associated features and identify likely pathogenic variants in previously undiagnosed DDD partic...

Background: Turner syndrome (TS) is one of the most common genetic disorders in females and occurs in phenotypic females who are missing all or part of one sex chromosome. While the most common mosaic forms of the disorder are 45,X/46,XX and 45,X/46,Xiq, mosaicism for cells containing Y chromosome material is well documented.Objective and hypotheses: Owing to increased risk of gonadoblastoma (GB), current recommendations are for elective gonadectomy foll...

Introduction: Turner syndrome (TS) is characterized by short stature and premature ovarian failure. Genetic component of TS patients with diagnosis of inflammatory bowel disease has not been largely studied.Case Report: A 94/12-year-old girl with history of Crohn’s disease was evaluated for short stature. Her disease was well controlled with medications, however she continued with linear growth failure. Medical history included...

Background: Gonadal dysgenesis in Turner syndrome (TS) results in pubertal delay or failure and infertility in most patients. However, up to 30% of girls with TS have spontaneous pubertal development and 2–5% have regular menstrual cycles before the onset of premature menopause. Serum anti-Mullerian (AMH) levels reflect the ovarian reserve in females, even in childhood.Objective and hypotheses: To Asses serum AMH levels in patients with TS and its r...

Introduction: Turner’s syndrome (TS) is caused by an abnormality of one of the X chromosomes. Short stature or slow growth is one of the first manifestations of TS and it is recommended that GH therapy should be initiated as soon as it becomes apparent that affected girls are not growing normally to optimise final adult height. Idiopathic intracranial hypertension (IIH) is a well-known side effect of GH therapy, and it has also been reported in girls with TS with or witho...

Mutations in genes of the RAS/MAPK signalling pathway have been shown to cause several syndromes characterized by dysmorphic features, growth retardation, cognitive impairment, heart disease and cutaneous abnormalities. The GHrh treatment has been used to improve growth in children with Noonan syndrome.Material and methods: 201 cases of patients referred with clinical suspicion of S. Noonan and other RASopathies was studied. Analysis of ...

Background: Short stature occurs in both Trisomy 21 and Turner syndrome. This unusual case has a de novo mutation of 47,X,del(X)(p22.3),+21 with clinical features of both syndromes. Growth assessment data and investigations was previously discussed in ESPE2016.Case: Following growth assessment due to parental concern that her short stature was too short for either syndrome and a falling height velocity of 3.5 cm/year at 2.8 years, the decision was made t...
