Abstract
Turner syndrome (TS) affects 50 per 100 000 females. TS affects multiple organs through all stages of life, necessitating multidisciplinary care. This guideline extends previous ones and includes important new advances, within diagnostics and genetics, estrogen treatment, fertility, co-morbidities, and neurocognition and neuropsychology. Exploratory meetings were held in 2021 in Europe and United States culminating with a consensus meeting in Aarhus, Denmark in June 2023. Prior to this, eight groups addressed important areas in TS care: (1) diagnosis and genetics, (2) growth, (3) puberty and estrogen treatment, (4) cardiovascular health, (5) transition, (6) fertility assessment, monitoring, and counselling, (7) health surveillance for comorbidities throughout the lifespan, and (8) neurocognition and its implications for mental health and well-being. Each group produced proposals for the present guidelines, which were meticulously discussed by the entire group. Four pertinent questions were submitted for formal GRADE (Grading of Recommendations, Assessment, Development and Evaluation) evaluation with systematic review of the literature. The guidelines project was initiated by the European Society for Endocrinology and the Pediatric Endocrine Society, in collaboration with members from the European Society for Pediatric Endocrinology, the European Society of Human Reproduction and Embryology, the European Reference Network on Rare Endocrine Conditions, the Society for Endocrinology, and the European Society of Cardiology, Japanese Society for Pediatric Endocrinology, Australia and New Zealand Society for Pediatric Endocrinology and Diabetes, Latin American Society for Pediatric Endocrinology, Arab Society for Pediatric Endocrinology and Diabetes, and the Asia Pacific Pediatric Endocrine Society. Advocacy groups appointed representatives for pre-meeting discussions and the consensus meeting.

Abstract
Cardiovascular related deaths account for over 40% of the excess mortality in Turner syndrome (TS). Hypertension, a modifiable risk factor for both aortic dilatation and dissection, is more commonly encountered in TS during childhood and adolescence. Treatment of hypertension is currently recommended beyond the age of 16 years in TS to help reduce the risk of aortic dissection. This study aims to determine the prevalence of hypertension in paediatric patients with TS and explore the associated methodologies of blood pressure evaluation reported in these studies. Three online databases were searched (Medline, Embase and Web of Science) for literature which reported a prevalence, or allowed calculation of prevalence, of hypertension in patients with TS who were 18 years of age or younger. Seventeen studies which met the primary eligibility criteria, with a total of 1948 patients, were included. The estimated pooled prevalence of hypertension in children and adolescents with TS was 16% (95% CI: 8.9-24.6%). There was significant heterogeneity detected between the studies. The prevalence of hypertension in those studies which assessed 24-h Ambulatory Blood Pressure Monitoring (ABPM) was 21.1% (95% CI: 15.2-27.6%) compared those which used another method of blood pressure measurement which was 13.5% (95% CI: 5.2-24.4%). Given the impact of hypertension with long-term health outcomes and the reversibility of these same outcomes by addressing abnormal blood pressure, prompt and early diagnosis of hypertension in young girls with TS should be prioritised. We recommend the use of 24-h ABPM in screening for hypertension in the paediatric TS population.

Abstract
Acquired cardiovascular diseases account for much of the increased risk of premature death in patients with Turner syndrome (TS). Hypertension is a major modifiable cardiovascular risk factor. It has a high prevalence in TS developing at an early age and thus leading to prolonged exposure to high blood pressure. The aetiology for hypertension in TS is largely unknown. It is likely multifactorial, and recent hypotheses include altered sympathetic tone, vasculopathy and endocrine factors. In this review article we aim to provide a comprehensive review of data on mechanisms of hypertension in TS and their implication for diagnostics and optimal choice of antihypertensive treatments. Ultimately this knowledge should help prevent hypertension-related complications, and improve quality of life and life expectancy for patients with TS.

Abstract
Turner syndrome (TS) is a condition in females missing the second sex chromosome (45,X) or parts thereof. It is considered a rare genetic condition and is associated with a wide range of clinical stigmata, such as short stature, ovarian dysgenesis, delayed puberty and infertility, congenital malformations, endocrine disorders, including a range of autoimmune conditions and type 2 diabetes, and neurocognitive deficits. Morbidity and mortality are clearly increased compared with the general population and the average age at diagnosis is quite delayed. During recent years it has become clear that a multidisciplinary approach is necessary toward the patient with TS. A number of clinical advances has been implemented, and these are reviewed. Our understanding of the genomic architecture of TS is advancing rapidly, and these latest developments are reviewed and discussed. Several candidate genes, genomic pathways and mechanisms, including an altered transcriptome and epigenome, are also presented.

Abstract
OBJECTIVE Hypertension contributes to increased risk of cardiovascular disease in patients with Turner syndrome (TS). Our objective was to evaluate blood pressure (BP) in girls with TS followed longitudinally through childhood and adolescence compared to a newly established BP reference material. DESIGN Cohort study with data collected from 1991 to 2019 consisting of a population-based reference cohort and a group of girls with TS followed at a single tertiary centre. PATIENTS/PARTICIPANTS Reference population of 1888 healthy girls with 4890 BP recordings and 60 girls with TS with 365 BP recordings. MEASUREMENTS Difference in diastolic BP (DBP) and systolic BP (SBP), expressed in standard deviation scores (SDS), between girls with TS and the reference population, unadjusted and adjusted for BMI. Difference in BP (SDS) between TS subgroups (karyotype, oestrogen treatment, cardiac diagnosis). RESULTS The girls with TS had significantly higher DBP (mean ± SD, 0.72 SDS ± 0.95; p < .001) and SBP (0.53 SDS ± 1.11; p = .001) than the reference population. Adjusted for BMI, girls with TS had significantly higher DBP (mean ± SE, 0.71 SDS ± 0.12; p < .001) but not SBP (0.17 SDS ± 0.16; p = .29). There was no significant difference in DBP (median, IQR: 0.97 SDS, 0.30-1.58 vs. 0.76 SDS, 0.10-1.20; p = .31) or SBP (0.51 SDS, 0.15-1.30 vs. 0.57 SDS, -0.30 to 1.05; p = .67) between individuals with or without a cardiac diagnosis. In the TS population, 55% (31/56) had at least one BP recording above the hypertension threshold. CONCLUSIONS Our findings indicate that standardised longitudinal routine monitoring of BP in girls with TS already in childhood is of utmost importance.

Abstract
Turner syndrome (TS) is a chromosomal disorder that affects 25-50 per 100,000 live born females. Patients with TS face a heavy burden of cardiovascular disease (congenital and acquired) with an increased risk of mortality and morbidity compared to the general population. Cardiovascular diseases are a major cause of death in females with TS. Approximately 50% of TS patients have a congenital heart abnormality, with a high incidence of bicuspid aortic valve (BAV), coarctation of the aorta (CoA) and generalised arteriopathy. Frequently, females with TS have systemic hypertension, which is also a risk factor for progressive cardiac dysfunction and aortopathy. This paper aims to provide an overview of the cardiovascular assessment, management and follow up strategies in this high-risk population of TS patients.

Abstract
Turner syndrome is a rare condition affecting 1 in 2500 female births and yet is the most common sex chromosome abnormality in women. Described as a cradle-to-grave condition, it requires life-long multidisciplinary management. Accelerated atresia of the primordial follicular pool leads to premature ovarian insufficiency, which is an almost inevitable feature of Turner syndrome, especially in 45XO karyotype. Many patients will have had their diagnosis made in childhood and require paediatric endocrinology management especially for induction of puberty. At the age of 18, patients may then be transitioned to an adult service. Continuation of multidisciplinary care for these women requires input from specialist services in menopause care, reproductive medicine and high-risk pregnancy, cardiology, endocrinology, bone health and psychosocial care. A gynaecologist may take on the mantle of lead clinician especially during the perceived reproductive years of a Turner syndrome patient's life, hinging together management input from other disciplines. This review attempts to summarise an overview of the involvement of such a multidisciplinary team in the management of a single but complex condition, through the lens of a gynaecologist.

Abstract
Turner syndrome is caused by complete or partial X monosomy in some or all cells. Cardiovascular complications are dominant, including increased blood pressure (BP), leading to early-onset hypertension. The aim is to describe the debut, development, and treatment of hypertension in Turner syndrome during a 12-year pragmatic interventional study to help identify risk factors associated with hypertension. One hundred and two women (aged 38±11 years, range: 18-62 years) with Turner syndrome verified by karyotyping (45, X: n=58 [57%]) were included consecutively. Ambulatory BPs were recorded over 24 hours with oscillometric measurements every 20 minutes. Antihypertensive treatment was recommended if the BP was above 135/85 mm Hg during the daytime. Overall, systolic BP, diastolic BP, and pulse pressure increased during the study, while heart rate decreased. The number of patients treated with antihypertensive medicine increased from 29 (28.71%) at baseline to 34 (53.13%) at the end of study. Twenty-four-hour systolic BP and 24-hour pulse pressure increased significantly with age, while 24-hour heart rate decreased with age, and diastolic BP was insignificantly affected by age. Antihypertensive treatment lowered systolic BP (24-hour: -5 mm Hg), diastolic BP (24-hour: -5 mm Hg), and diminished the pulse pressure (24-hour: -6 mm Hg) but did not affect nighttime systolic BP. Antihypertensive treatment did not affect heart rate. Our study showed that both systolic and diastolic BP increases significantly in women with Turner syndrome resulting in an increased risk of cardiovascular comorbidities. This increment should be considered of multifactorial origin with many contributing factors which is supported by our results.

Abstract
INTRODUCTION The incidence of Hashimoto's thyroiditis among patients who have Turner syndrome (TS) has increased, but Graves' disease (GD) in patients with TS is rarely reported. Here we report a rare case of TS with GD accompanied by hypogonadotropic hypogonadism. PATIENT CONCERNS We report the case of a 16-year-old girl who complained nervousness, fatigue, marasmus, heat intolerance, sweating, palpitation, and tremor lasting for more than a month. She had no medical history. DIAGNOSIS TS was diagnosed of the results of karyotyping demonstrated a gene karyotype of 46, X, i (X)(q10). GD was also diagnosed in this patient following the detection of thyroid function analysis. INTERVENTIONS Methimazole was administered after identification of GD. Due to the absence of secondary sex characteristics, the patient was given a conjugated estrogen preparation for 1 year, followed by the addition of estradiol cyproterone tablets for the onset of menstruation. OUTCOMES The hyperthyroidism symptoms of the patient had improved both clinically and laboratory tests after methimazole therapy. She was treated with estrogen and estradiol cyproterone, and the uterus and secondary sexual characteristics of the patient developed during 1 year follow-up. CONCLUSION TS generally presents as hypergonadotropic hypogonadism. However, hypogonadotropic hypogonadism cannot completely exclude TS. The diagnosis of this disease depends on chromosomal examination. The disease should be detected and treated as early as possible to improve life quality of the patient.

Abstract
Turner syndrome is a rare condition in women that is associated with either complete or partial loss of one X chromosome, often in mosaic karyotypes. Turner syndrome is associated with short stature, delayed puberty, ovarian dysgenesis, hypergonadotropic hypogonadism, infertility, congenital malformations of the heart, endocrine disorders such as type 1 and type 2 diabetes mellitus, osteoporosis and autoimmune disorders. Morbidity and mortality are increased in women with Turner syndrome compared with the general population and the involvement of multiple organs through all stages of life necessitates a multidisciplinary approach to care. Despite an often conspicuous phenotype, the diagnostic delay can be substantial and the average age at diagnosis is around 15 years of age. However, numerous important clinical advances have been achieved, covering all specialty fields involved in the care of girls and women with Turner syndrome. Here, we present an updated Review of Turner syndrome, covering advances in genetic and genomic mechanisms of disease, associated disorders and multidisciplinary approaches to patient management, including growth hormone therapy and hormone replacement therapy.

Abstract
OBJECTIVE Patients with Turner syndrome (TS) are at high risk for cardiovascular morbidity and mortality due to aortic dilation. We evaluated the prevalence of hypertension and its risk factors and investigated the relationship between systolic hypertension and aortic diameter in young patients with TS. DESIGN Observational, cross-sectional study. PATIENTS AND MEASUREMENTS Forty-two patients with TS (15-35 years) who had achieved final adult heights underwent 24-h ambulatory blood pressure monitoring (ABPM). Fasting glucose, insulin and lipid profiles were measured. The homeostasis model assessment of insulin resistance (HOMA-IR) was calculated. Echocardiography was performed to evaluate aortic diameters (aortic annulus, aortic root at the sinuses of Valsalva, sinotubular junction and ascending aorta), which were converted into Turner-specific z-scores. RESULTS Systolic and/or diastolic hypertension was identified in 71.4% (n = 30) of patients, as assessed by 24-hour ABPM. Twenty-eight patients (66.7%) were nondippers. Patients with systolic hypertension (n = 8, 19.0%) had a higher weight, waist circumference and HOMA-IR levels than those without hypertension (P < 0.05 for all). After adjusting for covariates, HOMA-IR was independently associated with systolic hypertension (odds ratio 10.1, P = 0.043). After adjusting for age and bicuspid aortic valve, systolic hypertension was independently related to increased aortic diameter at the aortic annulus (β = 1.064, P = 0.009) and sinotubular junction (β = 1.124, P = 0.016). CONCLUSIONS Hypertension is highly prevalent and independently associated with IR in young patients with TS. The significant relationship between systolic hypertension and aortic diameters underscores the importance of BP and IR control.

Brun S, Berglund A, Mortensen KH, Hjerrild BE, Hansen KW, Andersen NH, Gravholt CH. Blood pressure, sympathovagal tone, exercise capacity and metabolic status are linked in Turner syndrome. Clin Endocrinol (Oxf) 2019; 91:148-155.

Abstract
OBJECTIVES We studied cardiac autonomic changes in relation to metabolic factors, body composition and 24-hour ambulatory blood pressure measurements in Turner syndrome patients without known hypertension. DESIGN Cross sectional. PATIENTS Participants were 48 TS women and 24 healthy female controls aged over 18 years. METHODS Short-term power spectral analysis was obtained in supine-standing-supine position. Bedside tests included three conventional cardiovascular reflex tests of heart rate response to standing up, heart rate response to deep breathing and blood pressure response to standing up. Mean heart rate during the last 2 minutes of work was used to calculate the maximal aerobic power (VO2max ). RESULTS We found a significantly higher mean reciprocal of the heart rate per second (RR) in TS. Testing for interaction between position and status (TS or control), there were highly significant differences between TS and controls in high-frequency (HF) power, the coefficient of component variation (square root of HF power/mean RR) and low-frequency (LF): HF ratio, with a dampened decline in vagal activity among TS during standing. Bedside test showed TS had a significantly higher diastolic BP in the supine position compared to controls, and the adaptive rise in BP, when changing to upright position was reduced. VO2max and self-reported level of physical activity were significantly correlated to systolic ambulatory blood pressure both 24-hour and night diastolic ambulatory blood pressure. CONCLUSION Vagal tone and modulation of the sympathovagal balance during alteration in body position are impaired in TS. These changes can be risk factors for cardiovascular disease.

Impaired aortic distensibility and elevated central blood pressure in Turner Syndrome: a cardiovascular magnetic resonance study. J Cardiovasc Magn Reson 2018; 20:80. [PMID: 30541571 PMCID: PMC6292015 DOI: 10.1186/s12968-018-0497-0] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2017] [Accepted: 10/23/2018] [Indexed: 01/15/2023] Open
Abstract
BACKGROUND Women with Turner Syndrome have an increased risk for aortic dissection. Arterial stiffening is a risk factor for aortic dilatation and dissection. Here we investigate if arterial stiffening can be observed in Turner Syndrome patients and is an initial step in the development of aortic dilatation and subsequent dissection. METHODS Fifty-seven women with Turner Syndrome (48 years [29-66]) and thirty-six age- and sex-matched controls (49 years [26-68]) were included. Distensibility, blood pressure, carotid-femoral pulse wave velocity (PWV), the augmentation index (Aix) and central blood pressure were determined using cardiovascular magnetic resonance, a 24-h blood pressure measurement and applanation tonometry. Aortic distensibility was determined at three locations: ascending aorta, transverse aortic arch, and descending aorta. RESULTS Mean aortic distensibility in the descending aorta was significantly lower in Turner Syndrome compared to healthy controls (P = 0.02), however, this was due to a much lower distensibility among Turner Syndrome with coarctation, while Turner Syndrome without coarctation had similar distensibility as controls. Both the mean heart rate adjusted Aix (31.4% vs. 24.4%; P = 0.02) and central diastolic blood pressure (78.8 mmHg vs. 73.7 mmHg; P = 0.02) were higher in Turner Syndrome compared to controls, and these indices correlated significantly with ambulatory night-time diastolic blood pressure. The presence of aortic coarctation (r = - 0.44, P = 0.005) and a higher central systolic blood pressure (r = - 0.34, P = 0.03), age and presence of diabetes were inversely correlated with aortic distensibility in TS. CONCLUSION Aortic wall function in the descending aorta is impaired in Turner Syndrome with lower distensibility among those with coarctation of the aorta, and among all Turner Syndrome higher Aix, and elevated central diastolic blood pressure when compared to sex- and age-matched controls. TRIAL REGISTRATION The study was registered at ClinicalTrials.gov ( #NCT01678274 ) on September 3, 2012.

Abstract
BACKGROUND Turner syndrome (TS) is associated with an increased risk of cardiovascular disease. Non-high-density lipoprotein cholesterol (non-HDL-C) is a convenient measure of atherogenicity (normal concentration <120 mg/dL) but has not been investigated in TS. We aim to evaluate non-HDL-C patterns in a cohort of pediatric and young adult females with TS. METHODS A retrospective chart review was used to obtain demographics, body composition, genetic reports, and lipid profiles in females with TS. RESULTS Lipid profiles were assessed in 158 females (mean age 13.6 years). Mean non-HDL-C was 118.9 mg/dL (±32.0); the prevalence of high non-HDL-C (≥144 mg/dL) was 17.7% (n = 28). In TS females aged 8-17 years (n = 46), the prevalence of high non-HDL-C was 23.9% (95% CI 11.1-36.7; n = 11) between 2011 and 2012, compared to 9.2% (95% CI 5.6-14.1) in females of the same age in the general population reported in the National Health and Nutrition Examination Survey (NHANES) dataset (p < 0.005). Body mass index (BMI) accounted for only 6% of variance in non-HDL-C values (β coefficient = 1.31, p < 0.05). CONCLUSIONS Children and adolescents aged 8-17 years with TS appear to have a greater prevalence of adverse non-HDL-C levels compared to the general adolescent population. The prevalence of high non-HDL-C was not fully explained by BMI.

Abstract
BACKGROUND Cardiovascular disease (CVD) presents the most serious health problems and contributes to the increased mortality in young women with Turner syndrome. Arterial hypertension in Turner syndrome patients is significantly more prevalent than that in a general age-matched control group. The aetiology of hypertension in Turner syndrome varies, even in the absence of cardiac anomalies and obvious structural renal abnormalities. Pheochromocytoma is an extremely rare cause among various etiologies for hypertension in patients with Turner syndrome. Here, we reported a pheochromocytoma as a rare cause of hypertension in Turner syndrome patient. CASE PRESENTATION A 21-year-old woman who has diagnosed with Turner syndrome with a karyotype of 46,X,i(X)(q10) visited for hypertension and mild headache. Transthoracic echography (TTE) showed no definite persistent ductus arteriosus shunt flow and cardiac valve abnormalities. Considering other important secondary causes like pheochromocytoma, hormonal studies were performed and the results showed increased serum norepinephrine, serum normetanephrine, and 24 h urine norepinephrine. We performed an abdominal computed tomography (CT) to confirm the location of pheochromocytoma. Abdominal CT showed a 1.9 cm right adrenal mass. I-131 meta-iodobenzylguanidine (MIBG) scintigraphy showed a right adrenal uptake. Laparoscopic adrenalectomy was performed and confirmed a pheochromocytoma. After surgery, blood pressure was within normal ranges and postoperative course was uneventful, and no recurrence developed via biochemical tests and abdominal CT until 24 months. CONCLUSION Our case and previous literatures suggest that hypertension caused by pheochromocytoma which is a rare but important and potentially lethal cause of hypertension in Turner syndrome. This case underlines the importance of early detection of pheochromocytoma in Turner syndrome. Clinicians should keep in mind that pheochromocytoma can be a cause of hypertension in patients with Turner syndrome.

Determinants of Increased Aortic Diameters in Young Normotensive Patients With Turner Syndrome Without Structural Heart Disease. Pediatr Cardiol 2018; 39:786-793. [PMID: 29392348 DOI: 10.1007/s00246-018-1821-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2017] [Accepted: 01/20/2018] [Indexed: 01/15/2023]
Abstract
Factors associated with aortic dilation and dissection in patients with Turner syndrome (TS) remain unclear. We assessed magnetic resonance imaging-based aortic diameters at nine predefined anatomic positions and examined associations of increased aortic diameters with B-type natriuretic peptide (BNP), A-type NP (ANP), growth hormone treatment, insulin-like growth factor 1 (IGF1), and estrogen status. Forty-seven patients with TS aged 7.3-21 years and 34 healthy peers were enrolled in this study. Aortic diameters were higher in patients with TS at three positions than in controls (p < 0.05). History of GH treatment, pubertal status, and serum estradiol levels were not associated with increased aortic diameters. Patients with TS had higher plasma BNP and ANP levels than controls. BNP and IGF1 were independently associated with the increase in aortic diameters in TS at three positions of the ascending aorta (R2 = 0.361-0.458, p < 0.05 for all). At two positions of the descending aorta, only BNP emerged as an independent variable (R2 = 0.130-0.139, p < 0.05). We conclude that young, normotensive patients with TS had greater aortic diameters at several positions than healthy controls. BNP and IGF1 were independently associated with increased aortic diameters in TS.

Abstract
Turner syndrome affects 25-50 per 100,000 females and can involve multiple organs through all stages of life, necessitating multidisciplinary approach to care. Previous guidelines have highlighted this, but numerous important advances have been noted recently. These advances cover all specialty fields involved in the care of girls and women with TS. This paper is based on an international effort that started with exploratory meetings in 2014 in both Europe and the USA, and culminated with a Consensus Meeting held in Cincinnati, Ohio, USA in July 2016. Prior to this meeting, five groups each addressed important areas in TS care: 1) diagnostic and genetic issues, 2) growth and development during childhood and adolescence, 3) congenital and acquired cardiovascular disease, 4) transition and adult care, and 5) other comorbidities and neurocognitive issues. These groups produced proposals for the present guidelines. Additionally, four pertinent questions were submitted for formal GRADE (Grading of Recommendations, Assessment, Development and Evaluation) evaluation with a separate systematic review of the literature. These four questions related to the efficacy and most optimal treatment of short stature, infertility, hypertension, and hormonal replacement therapy. The guidelines project was initiated by the European Society for Endocrinology and the Pediatric Endocrine Society, in collaboration with The European Society for Pediatric Endocrinology, The Endocrine Society, European Society of Human Reproduction and Embryology, The American Heart Association, The Society for Endocrinology, and the European Society of Cardiology. The guideline has been formally endorsed by the European Society for Endocrinology, the Pediatric Endocrine Society, the European Society for Pediatric Endocrinology, the European Society of Human Reproduction and Embryology and the Endocrine Society. Advocacy groups appointed representatives who participated in pre-meeting discussions and in the consensus meeting.

Abstract
Turner syndrome (TS) is a chromosomal disorder that affects 1:2,000 females. It results from either the complete or partial loss of the X chromosome as well as other aberrations. Clinical features of TS include short stature, delayed puberty, and congenital cardiac malformations. TS children also have an increased prevalence of cardiometabolic risk factors, which predisposes them to complications like coronary artery disease, cerebrovascular-related deaths, and aortic dissection. Early cardiac imaging, such as echocardiography and cardiac magnetic resonance imaging, are recommended to detect underlying aortic pathology. However, these modalities are limited by cost, accessibility, and are operator dependent. In view of these shortcomings, alternative methods, like vascular biomarkers, are currently being explored. There are only a few studies that have examined the relationship between B-type natriuretic peptide (BNP), N-terminal pro BNP (NT pro-BNP), and osteoprotegerin (OPG) and aortic disease in TS, and thus the data are only in proof-of-concept stages. Further meticulous longitudinal studies are required before BNP, NT pro-BNP, and OPG are used as vascular biomarkers for the detection of aortic disease in childhood and adolescent TS.

Abstract
OBJECTIVE Seamless transition of endocrine patients from the paediatric to adult setting is still suboptimal, especially in patients with complex disorders, i.e., small for gestational age, Turner or Prader-Willi syndromes; Childhood Cancer Survivors, and those with childhood-onset growth hormone deficiency. METHODS An expert panel meeting comprised of European paediatric and adult endocrinologists was convened to explore the current gaps in managing the healthcare of patients with endocrine diseases during transition from paediatric to adult care settings. RESULTS While a consensus was reached that a team approach is best, discussions revealed that a 'one size fits all' model for transition is largely unsuccessful in these patients. They need more tailored care during adolescence to prevent complications like failure to achieve target adult height, reduced bone mineral density, morbid obesity, metabolic perturbations (obesity and body composition), inappropriate/inadequate puberty, compromised fertility, diminished quality of life and failure to adapt to the demands of adult life. Sometimes it is difficult for young people to detach emotionally from their paediatric endocrinologist and/or the abrupt change from an environment of parental responsibility to one of autonomy. Discussions about impending transition and healthcare autonomy should begin in early adolescence and continue throughout young adulthood to ensure seamless continuum of care and optimal treatment outcomes. CONCLUSIONS Even amongst a group of healthcare professionals with a great interest in improving transition services for patients with endocrine diseases, there is still much work to be done to improve the quality of healthcare for transition patients.

Abstract
Cardiovascular disease is the major factor that reduces lifespan in Turner syndrome. High blood pressure (BP) is common in Turner syndrome and is the most easily treatable cardiovascular risk factor. We studied the prevalence of elevated screening systemic BP, awareness of the problem, and its clinical associations in a large group of girls attending the annual meeting of the Turner Syndrome Society of the United States. Among 168 girls aged 2 to 17 years, 42% had elevated screening BP (systolic and diastolic), yet only 8% reported a previous diagnosis of hypertension. History of aortic coarctation repair (17%) was positively associated with elevated systolic BP (52% versus 32%; P<0.05). Elevated systolic BP was positively associated with obesity (56% versus 31%; P<0.05). Because the prevalence of obesity in the studied population was similar to Center for Disease Control published data for obesity in all girls and the prevalence of increased BP is approximately twice that of the general population, the Turner syndrome phenotype/genotype probably includes an intrinsic risk for hypertension. Obesity and repaired aortic coarctation increase this risk further. There seems to be a BP awareness gap in girls with Turner syndrome. Because girls living with Turner syndrome are a sensitized population for hypertension, further study may provide clues to genetic factors leading to a better understanding of essential hypertension in the general population.

Abstract
Turner syndrome is a rare chromosomal disorder with complete or partial absence of one X chromosome that only occurs in women. Clinical presentation is variable, but congenital and acquired cardiovascular diseases are frequently associated diseases that add significantly to the increased morbidity and mortality in Turner syndrome patients. Arterial hypertension is reported in 13-58% of adult Turner syndrome patients and confers an increased risk for stroke and aortic dissection. Hypertension can be present from childhood on and is reported in one-quarter of the paediatric Turner syndrome patients. This article reviews the prevalence and cause of arterial hypertension in Turner syndrome and describes the relationship between blood pressure, aortic dilation and increased cardiovascular risk. We compare current treatment strategies and also propose an integrated practical approach for the diagnosis and treatment of hypertension in Turner syndrome applicable in daily practice.

Abstract
Introduction: In Turner syndrome, cardiovascular complications are the most important causes of early mortality. Congenital cardiovascular abnormalities are found in approximately one third of Turner syndrome patients. Developments in diagnosis and treatment have decreased the rate of mortality related to these abnormalities. In recent years, many papers have mentioned that coronary artery disease developing at early ages in patients with Turner syndrome causes sudden deaths. Case Presentation: The patient, a 27-year-old female was admitted to the emergency room with chest pain at rest. She was diagnosed with Turner Syndrome in her teenage years due to amenorrhea. Patients with ECG changes and cardiac enzyme elevations were treated with acute coronary syndrome. Conclusions: The young woman with Turner Syndrome have several risk factors for early Coronary Artery Disease development. In such cases, dramatic results like sudden death or heart attack at an early age may occur in cases of insufficient follow-up and treatment.

Abstract
PURPOSE Patients with Turner syndrome (TS) are frequently affected by congenital as well as acquired cardiovascular diseases. The aim of the study was to evaluate the blood pressure, the endothelial function (FMD) and the intima media thickness (IMT) at the level of the common carotid arteries in a group of girls and young women with TS in comparison to healthy controls. METHODS We evaluated 40 unselected TS patients, with a mean age of 18.6 ± 0.9 years and 103 age matched healthy subjects. MAIN OUTCOME MEASURES blood pressure, FMD and IMT. RESULTS No differences were found in systolic and diastolic blood pressure between TS patients and controls. FMD was higher in TS than in controls (14.2 ± 1.4 vs 11.4 ± 0.3%, p = 0.005) whereas IMT was not statistically different in the two study groups (0.54 ± 0.04 vs 0.57 ± 0.01 mm). However, in TS patients an inverse correlation was found between FMD and both age (-0.03 ± 0.01, p = 0.003) and years of estrogen therapy (-0.72 ± 0.31, p < 0.03), whereas a positive correlation was found between IMT and age (R 2 = 0.35, p < 0.0001) and estrogen therapy duration (R 2 = 0.65, p < 0.0001), suggesting a clear tendency toward a premature decrease in FMD and premature increase in IMT compared to controls. CONCLUSIONS Young TS patients show an arterial wall which is functionally and structurally comparable or better than controls. They show, however, a premature derangement of the arterial function and structure, which seems to be partly influenced by age and duration of oestrogen treatment.

Abstract
BACKGROUND Turner syndrome is characterized by a great variability of clinical manifestations caused by a total or partial loss of X-chromosome. PATIENTS AND METHODS A retrospective, descriptive study of the diagnosis, course, and current status of patients with Turner syndrome followed up at our section over the past 40 years, based on review of medical records supplemented with a telephone survey. RESULTS Forty-five female patients with a current mean age of 22.95years (range 2-38) and a mean age at diagnosis of 4.71 were included. Sixty-three percent of them showed a mosaic karyotype. Short stature was the most common reason for consultation (54%), with increased prenatal diagnosis in most recent cases. Seventy-two percent have been treated with growth hormone, together with oxandrolone in 26%. Final stature was short in 69% of patients. Gonadal failure was found in 66%; most of whom received replacement therapy. Three patients achieved pregnancy by oocyte donation. The 31 adult patients are mainly monitored by the endocrinology (37.5%) and/or gynecology (34.4%) departments. As regards psychosocial aspects, 22% required support during school, and 80% completed middle to high level education. Two patients died, one due to dissecting aortic aneurysm and the other one, who had multiple pathological conditions, from respiratory failure. CONCLUSIONS Short stature is the main cause of diagnosis in patients with Turner syndrome; most cases show genetic mosaicism. The most common clinical manifestations include short stature and gonadal failure. Eighty percent of patients complete middle or high education. In adulthood, follow-up is irregular, sometimes scarce, and clearly improvable.

Abstract
BACKGROUND An unfavourable cardiovascular and metabolic phenotype causes threefold excess mortality in Turner syndrome (TS), and perturbed cardiac substrate metabolism is increasingly recognized as a common component of cardiovascular and metabolic diseases. We therefore hypothesized that myocardial glucose uptake (MGU) is reduced in TS and that growth hormone (GH) treatment improves MGU. To this end, this controlled trial elucidates MGU in TS and the impact of 6 months of growth hormone treatment on MGU. METHODS AND RESULTS Women with TS (n = 9) were examined at baseline, sequentially treated with either Norditropin(®) SimpleXx or placebo and re-examined after 6 months. MGU and myocardial blood flow (MBF) were measured using 2-deoxy-2-[18F]fluoro-D-glucose positron emission tomography (FDG-PET) during a hyperinsulinaemic euglycaemic clamp (at baseline and 6 months). Blood pressure measurement, blood sampling, echocardiography and dual energy X-ray absorptiometry scan were also performed. Age-matched female controls (n = 9) were examined once. Baseline MGU was reduced in TS (0.24 ± 0.08 vs. 0.36 ± 0.13 μmol/g/min in controls; P = 0.036) despite similar insulin sensitivity (whole body glucose uptake (M-value): 9.69 ± 1.86 vs. 9.86 ± 2.58 mg/(min*kg) in controls; P = 0.9). Six months of GH carried no impact on MGU (0.25 ± 0.08 vs. 0.26 ± 0.12 μmol/g/min in the placebo group; P = 0.8). Plasma glucose, low-density cholesterol and triglycerides increased, while M-value and exercise capacity decreased during 6 months of GH treatment. CONCLUSION MGU is reduced in TS despite normal insulin sensitivity. GH treatment does not alter MGU despite decreased whole body insulin sensitivity. A perturbed cardiac glucose uptake appears to be a feature of TS.

Abstract
There is a general lack of awareness of the risk of aortic dissection in Turner syndrome (TS) from both patients with TS and their physicians. Patients often ignore symptoms for up to 24 h before seeking medical advice, significantly increasing their risk of death. A clinical profile of those at risk of dissection is emerging and includes the presence of congenital heart defects, aortic dilatation and hypertension. MRI has revolutionised the visualisation of cardiovascular anatomy in TS but remains underutilised, especially in children and adolescents, and there is currently little guidance on blood pressure (BP) assessment or hypertension management. Children and adolescents with TS at risk of dissection could be easily identified by timely imaging and BP assessment. This would allow medical management or surgical intervention to be put in place to reduce the risk of this major, and often fatal, complication. Since guidance is lacking, we have reviewed the literature on the risk factors for dissection in TS during childhood and adolescence, and make recommendations on the assessment and management of these patients.

Abstract
OBJECTIVES Factors contributing to arteriopathy in patients with Turner syndrome (TS) remain unclear. We assessed arterial stiffness in young, normotensive patients with TS and correlated arterial stiffness with vascular biomarkers, GH treatment and oestrogen exposure. Sixty-one patients with TS (mean age, 12·6 years; range 6·6-21·3 years) were matched for age and sex with 61 healthy peers. Associations between arterial stiffness and high-sensitivity C-reactive protein (hsCRP), B-type natriuretic peptide (BNP), atrial NP (ANP), plasma aldosterone/plasma renin activity (PRA), IGF1 and IGFBP3 were examined after adjusting for well-established confounders of vascular disease. RESULTS Carotid intima media thickness standard deviation score (SDS), arterial stiffness index SDS and incremental modulus of elasticity SDS were higher, and distensibility coefficient SDS was lower in patients with TS. The duration of GH treatment and oestrogen exposure was not associated with indices of arterial stiffness. TS patients had higher hsCRP, BNP and ANP. Plasma aldosterone/PRA, IGF1 and IGFBP3 were similar in patients and controls. Multivariable regression analyses (R(2) = 0·200-0·668, P < 0·01) showed that BNP was associated with all indices of arterial stiffness. We found that hsCRP was associated with distensibility coefficient SDS (β = -0·16, P < 0·01). TS was independently associated with increased arterial stiffness (β = 0·420-3·424, P < 0·001 for all, R(2) = 0·06-0·31). CONCLUSIONS Young, normotensive TS patients had increased arterial stiffness than that of healthy peers. BNP, and possibly hsCRP, was independently associated with arterial stiffness in TS. Further research will determine any causal inference of these relationships.

Abstract
Central blood pressure may be more closely associated with cardiovascular events than peripheral blood pressure. The aim of the present study was to investigate central blood pressure responses to exercise. Apparently healthy 18 subjects were enrolled in the study (38 ± 6 years) and changes in central and brachial blood pressure were recorded in response to ergometer and hand-grip exercises. Central blood pressure was estimated using an automated device (Omron HEM-9000AI). Systolic brachial blood pressure was increased after both ergometer (from 119 ± 10 to 172 ± 16 mmHg; P < 0.001) and hand-grip (from 118 ± 8 to 122 ± 9 mmHg; P = 0.001) exercises, but central systolic blood pressure was increased only after hand-grip exercise (from 117 ± 11 to 121 ± 12 mmHg; P = 0.002). The radial augmentation index was increased after hand-grip exercise, whereas ergometer exercise reduced this index. Heart rate was increased only after ergometer exercise. Thus, isometric, but not isotonic, exercise may increase central blood pressure in overall healthy subjects. The response of central blood pressure, which is a better index of cardiac load than peripheral blood pressure, to hand-grip exercise may be useful in evaluating cardiovascular risk.

Abstract
Objectives QT-interval prolongation of unknown aetiology is common in Turner syndrome. This study set out to explore the presence of known long QT mutations in Turner syndrome and to examine the corrected QT-interval (QTc) over time and relate the findings to the Turner syndrome phenotype. Methods Adult women with Turner syndrome (n = 88) were examined thrice and 68 age-matched healthy controls were examined once. QTc was measured by one blinded reader (intra-reader variability: 0.7%), and adjusted for influence of heart rate by Bazett’s (bQTc) and Hodges’s formula (hQTc). The prevalence of mutations in genes related to Long QT syndrome was determined in women with Turner syndrome and a QTc >432.0 milliseconds (ms). Echocardiographic assessment of aortic valve morphology, 24-hour blood pressures and blood samples were done. Results The mean hQTc in women with Turner syndrome (414.0±25.5 ms) compared to controls (390.4±17.8 ms) was prolonged (p<0.001) and did not change over time (416.9±22.6 vs. 415.6±25.5 ms; p = 0.4). 45,X karyotype was associated with increased hQTc prolongation compared to other Turner syndrome karyotypes (418.2±24.8 vs. 407.6±25.5 ms; p = 0.055). In women with Turner syndrome and a bQTc >432 ms, 7 had mutations in major Long QT syndrome genes (SCN5A and KCNH2) and one in a minor Long QT syndrome gene (KCNE2). Conclusion There is a high prevalence of mutations in the major LQTS genes in women with TS and prolonged QTc. It remains to be settled, whether these findings are related to the unexplained excess mortality in Turner women.

Abstract
BACKGROUND Identification of the subset females with Turner syndrome who face especially high risk of aortic dissection is difficult, and more optimal risk assessment is pivotal in order to improve outcomes. This study aimed to provide comprehensive, dynamic mathematical models of aortic disease in Turner syndrome by use of cardiovascular magnetic resonance (CMR). METHODS A prospective framework of long-term aortic follow-up was used, which comprised diameters of the thoracic aorta prospectively assessed at nine positions by CMR at the three points in time (baseline [n = 102, age 38 ± 11 years], follow-up [after 2.4 ± 0.4 years, n = 80] and end-of-study [after 4.8 ± 0.5 years, n = 78]). Mathematical models were created that cohesively integrated all measurements at all positions, from all visits and for all participants, and using these models cohesive risk factor analyses were conducted based on which predictive modeling was performed on which predictive modelling was performed. RESULTS The cohesive models showed that the variables with effect on aortic diameter were aortic coarctation (P < 0.0001), bicuspid aortic valves (P < 0.0001), age (P < 0.0001), diastolic blood pressure (P = 0.0008), body surface area (P = 0.015) and antihypertensive treatment (P = 0.005). Oestrogen replacement therapy had an effect of borderline significance (P = 0.08). From these data, mathematical models were created that enabled preemption of aortic dilation from CMR derived aortic diameters in scenarios both with and without known risk factors. The fit of the models to the actual data was good. CONCLUSION The presented cohesive model for prediction of aortic diameter in Turner syndrome could help identifying females with rapid growth of aortic diameter, and may enhance clinical decision-making based on serial CMR.

Abstract
BACKGROUND AND OBJECTIVES Turner syndrome (TS) confers increased lifetime risk of type 2 diabetes mellitus and cardiovascular disease. We compared cardiometabolic risk factors and measures of subcutaneous, visceral adipose tissue and intra-myocellular lipid between young TS girls and an age- and BMI-standard deviation scores (SDS)-matched healthy female cohort. PATIENTS AND METHODS A cross-sectional cohort study was conducted at the Hospital for Sick Children, Toronto. Nineteen TS and 17 control girls (13.7 ± 2.5 vs 12.7 ± 3.4 years of age, respectively, P = 0.30). Multiple-sample oral glucose tolerance test with measurement of fasting insulin, LDL, HDL, triglycerides, adiponectin and highly sensitive C-reactive protein (hsCRP) was performed. Subcutaneous adipose tissue, visceral adipose tissue intramyocellular lipid levels evaluated by magnetic resonance techniques. Insulin secretion (IS), sensitivity (Si) and the insulin secretion-sensitivity index (ISSI-2) were calculated from oral glucose tolerance test data. RESULTS Five TS and no controls had impaired fasting glucose or impaired glucose tolerance; none had type 2 diabetes mellitus. Insulin sensitivity and insulin secretion were similar between groups; ISSI-2 was lower in TS (923.5 ± 307.3 vs 659.1 ± 387.3; P = 0.03). TS girls had higher blood pressure (82.5 ± 13.6 vs 73.5 ± 5.5 mmHg; P = 0.0146), waist circumference (76.0 ± 11.8 vs 65.9 ± 9.7; P = 0.0087) and subcutaneous adipose tissue (135.6 ± 88.6 vs 69.3 ± 59.9; P = 0.01) than controls. Visceral adipose tissue, intramyocellular lipid levels and adiponectin were not different between groups. TS girls also had higher triglycerides (1.1 ± 0.6 vs 0.7 ± 0.3; P = 0.003), total cholesterol (4.4 ± 0.7 vs 3.9 ± 0.4; P = 0.02) and hsCRP (2.0 ± 1.9 vs 0.8 ± 0.3; P = 0.01). CONCLUSIONS TS girls exhibit more cardiometabolic risk factors and reduced beta cell function compared with age- and BMI-SDS-matched girls. Increased awareness of early risk of type 2 diabetes mellitus and hypertension in TS girls is needed.

Abstract
CONTEXT Turner syndrome (TS) is a chromosomal disorder occurring in approximately 1 in 2500 live births. Individuals with TS report lower levels of physical activity than healthy control (HC) subjects. Cardiorespiratory limitations may contribute to the observed reduction in physical activity. OBJECTIVE The objective of this study was to compare muscle metabolism of patients with TS vs HC subjects before and after exercise using exercise testing, magnetic resonance imaging, and magnetic resonance spectroscopy techniques. DESIGN We hypothesized that girls and adolescents with TS would have muscle metabolic abnormalities not present in the HC population. SETTING The research was conducted at the Hospital for Sick Children in Toronto, Ontario, Canada. PARTICIPANTS Fifteen participants with TS were age-, activity-, and body mass index Z-score-matched with 16 HC subjects. MAIN OUTCOME MEASURES (31)P magnetic resonance spectroscopy was used to characterize muscle metabolism at rest and after 30 seconds of high-intensity exercise, 60 seconds of moderate-intensity exercise, and 5 minutes of low-intensity exercise. RESULTS While achieving the same workloads, participants with TS exhibited a greater difference between rest and end-exercise pH compared with HC subjects after 30 seconds (TS, 0.29 ± 0.04; HC, 0.21 ± 0.08; P = .03) and 90 seconds (TS, 0.47 ± 0.22; HC, 0.32 ± 0.13; P = .02) of exercise. During the 5-minute exercise test, similar workloads were achieved between groups; however, ATP production was greater in participants with TS vs the HC subjects via all 3 bioenergetic pathways (total ATP: TS, 0.90 ± 0.34; HC, 0.60 ± 0.25; P = .01). CONCLUSIONS The results of this study suggest that patients with TS exhibit greater anaerobic stress during exercise than HC subjects, which may lead to symptoms of increased muscle fatigue with short bursts of activity. Recovery metabolism after exercise appears to be similar between participants with TS and HC subjects, which is suggestive of normal mitochondrial metabolism and oxygen transport.

Abstract
Obesity, hypertension, and coronary artery disease are prevalent in the general population and well recognized as contributors to cardiac morbidity and mortality. With surgical and medical advances, there is a growing and aging population with congenital heart disease who are also at risk of developing these comorbidities. In addition, some congenital cardiac lesions predispose patients to conditions such as hypertension or coronary artery disease. The effect of these comorbidities on the structurally abnormal heart is not well understood, but might be very important, especially in those with residual abnormalities. Thus, in addition to surveillance for and treatment of late complications it is important for the congenital cardiologist to consider and aggressively manage acquired comorbidities. In this review we explore the prevalence of hypertension, obesity, and coronary artery disease, discuss congenital lesions that predispose to these conditions and review management strategies for this unique population.

Abstract
UNLABELLED Turner syndrome (TS), the result of a structurally abnormal or absent X chromosome, occurs in one in 2 000 live born females. The phenotype is highly variable, but short stature and gonadal dysgenesis are usually present. The main objective in adults with TS is health surveillance, but TS still causes a reduction in life expectancy of up to 13 years, with cardiovascular disease, congenital or acquired, as the major cause of an early death. While it has been established that all women with TS should undergo in-depth cardiovascular examination at diagnosis, advice on the cardiovascular management of women with TS is limited. Here, we provide a summary of our current practice within a multidisciplinary team, supported by our expertise in various aspects of cardiovascular risk management, and the evidence from research where it is available, with the aim of providing optimal support to our patients with TS. BACKGROUND A dedicated Adult Turner Clinic was established in South East Scotland in 2002. This gynaecology-led clinic serves a population of roughly 1·2 million and, currently, reviews around 50 women with TS annually. Referrals for adult care come from paediatrics or general practice. Following a series of individual case discussions regarding the management of more complex cardiovascular problems, we have assembled a dedicated multidisciplinary group to determine a timely cardiovascular screening strategy, a basis for specialist referral, and appropriate hypertension management. This team now includes a paediatric endocrinologist, gynaecologist, cardiologist (with an interest in inherited disorders), vascular radiologist and hypertension specialist. Here, we review the literature on cardiovascular disease in women with TS and, make recommendations, based on relatively limited high-quality evidence, together with our experience, on the optimal timing of cardiovascular screening.

Abstract
CONTEXT The phenotype of 45,X/46,XY mosaicism is heterogeneous ranging from females with Turner syndrome (TS) to apparently normal males. Males with 45,X/46,XY frequently show stigmata typically associated with TS. We hypothesised that males with 45,X/46,XY have similar cardiovascular pathology as females with 45,X/46,XY. OBJECTIVE To investigate cardiovascular abnormalities in 45,X/46,XY males and to compare them with 45,X/46,XY females. DESIGN Patients with 45,X/46,XY mosaicism were selected from the Belgian Registry for Growth and Puberty problems and via the multidisciplinary clinic for disorders of sexual development. PATIENTS EIGHTEEN PATIENTS WERE INCLUDED: 8 raised as females (F) and 10 as males (M). INTERVENTION Complete cardiac examination with blood pressure measurement, ECG, echocardiography and MRI. MAIN OUTCOME MEASUREMENT Cardiac parameters were registered for both groups. In a second phase, clinical features and external masculinisation score (EMS) were retrospectively collected from the medical files. RESULTS A structural heart defect was diagnosed before inclusion in 1 F with coarctation and 1 M with spontaneously closed VSD. A bicuspid aortic valve was found in 8 (3 F, 5 M). Dilation of the ascending aorta was present in 4 M and was severe in 2 young boys. QTc was prolonged in 3 F and 2 M. CONCLUSION Males with 45,X/46,XY mosaicism have similar cardiovascular pathology as 45,X/46,XY females. Dilation of the ascending aorta can be important, also in males. We advise cardiac screening and life-long monitoring in all males with 45,X/46,XY mosaicism according to the existing guidelines for Turner syndrome.

Abstract
Cardiovascular disease is emerging as a cardinal trait of Turner syndrome, being responsible for half of the 3-fold excess mortality. Turner syndrome has been proposed as an independent risk marker for cardiovascular disease that manifests as congenital heart disease, aortic dilation and dissection, valvular heart disease, hypertension, thromboembolism, myocardial infarction, and stroke. Risk stratification is unfortunately not straightforward because risk markers derived from the general population inadequately identify the subset of females with Turner syndrome who will suffer events. A high prevalence of endocrine disorders adds to the complexity, exacerbating cardiovascular prognosis. Mounting knowledge about the prevalence and interplay of cardiovascular and endocrine disease in Turner syndrome is paralleled by improved understanding of the genetics of the X-chromosome in both normal health and disease. At present in Turner syndrome, this is most advanced for the SHOX gene, which partly explains the growth deficit. This review provides an up-to-date condensation of current state-of-the-art knowledge in Turner syndrome, the main focus being cardiovascular morbidity and mortality. The aim is to provide insight into pathogenesis of Turner syndrome with perspectives to advances in the understanding of genetics of the X-chromosome. The review also incorporates important endocrine features, in order to comprehensively explain the cardiovascular phenotype and to highlight how raised attention to endocrinology and genetics is important in the identification and modification of cardiovascular risk.

Abstract
OBJECTIVE Turner syndrome (TS) is characterized by growth retardation, hypogonadism and a high risk of cardiovascular complications and atherosclerosis; case reports suggest that thrombo-embolic complications may be present. DESIGN Cross-sectional study. PATIENTS Sixty women with TS. MEASUREMENTS We characterized the activities of the haemostatic system, elucidated by the assessment of a panel of clotting factors and thrombosis risk factors and related these findings to carotid intima thickness (CIMT) and blood pressure. RESULTS Most (81%) received hormone replacement therapy. The medians of all measured factors and inflammatory parameters were not different from normative data, but many cases displayed values of C-reactive protein (CRP) (40%), fibrinogen (15%), fibrin D-dimer (15%), factor VIII (25%), von Willebrand factor (vWF) (15%), cholesterol and liver parameters that were greater than normative limits. CRP, fibrinogen, vWF, factor VIII and liver parameters were highly and positively correlated. Haemostatic variables were positively related to both CIMT and blood pressure. The Factor V Leiden G1691A gene polymorphism heterozygosity was detected in 12·5%. CONCLUSION We describe a significant proportion of individual TS females having high levels of vWF, factor VIII, fibrinogen and CRP (15-40%) and an increased frequency of the Leiden mutation, with important associations with CIMT and blood pressure, suggesting that a subset of TS may have an unfavourable haemostatic balance, which may contribute to the increased risk of premature ischaemic heart disease and possibly increase the risk of deep venous and portal vein thrombosis.

Abstract
Cardiovascular Disorders of Turner's Syndrome: A ReviewA series of cardiovascular abnormalities may be associated with Turner's Syndrome (TS). Over 50% of the reported cardiovascular malformations have been bicuspid aortic valve or coarctation of the aorta alone. or in a combination, which may lead to a higher risk for infective endocarditis. Isolated dilation of the ascending aorta was often seen in TS, while aortic dissection has been increasingly observed in recent years. The aortic root dilation was found more likely to be due to a mesenchymal defect rather than atherosclerotic changes. Women with TS are often hypertensive as a result of aortic abnormality or renal vascular disorder. They have an increased risk of developing neoplasms, such as gonadoblastoma and dysgerminoma, and therefore they may require regular monitoring while receiving hormone therapy. In patients with gonadal dysgenesis, exogenous estrogen treatment poses a problem of connective tissue disorders of the great vessels. To resolve the contradiction between exogenous estrogen therapies and the hold-up of the progression of the connective tissue abnormality is a topic to be coped with. Careful clinical assessment is mandatory in the evaluation of patients with TS with cardiovascular abnormalities.

Abstract
OBJECTIVE To investigate whether eye-gaze avoidance, a striking phenotypic feature in fragile X syndrome (FXS), is associated with high levels of "hyperarousal" during social interactions with others. To date, almost all studies in this area have been confounded by inclusion of task demands in addition to social demands. METHOD We monitored the cardiovascular activity and eye-gaze avoidance of 50 boys and girls with FXS aged 5 to 20 years during a 25-minute intensive social interaction session with an unfamiliar experimenter. To control for possible family and genetic factors in cardiovascular activity, we compared each child with FXS with their same-sex typically developing biological sibling. RESULTS Participants with FXS obtained significantly higher heart rates, lower vagal tone, and lower heart rate variability estimates both at baseline and during the social interaction session compared with their typically developing siblings. Although eye-gaze avoidance occurred at significantly higher levels in the children with FXS, this behavior decreased slightly over the course of the session (a "warm-up" effect) and did not seem to be associated with cardiovascular activity. In the girls with FXS, higher levels of the fragile X mental retardation protein were associated with higher (and more typical) heart rate variability. CONCLUSIONS These data suggest that both sympathetic and parasympathetic nervous systems are dysregulated in FXS. However, given that prolonged exposure to social demands does not inevitably lead to increased anxiety or "hyperarousal," professionals should not be deterred from providing much needed social skills interventions for individuals with FXS.

Abstract
Cardiovascular complications in Turner's syndrome are the most common cause of excess early mortality, with a life expectancy that may be reduced by more than 10 years. Congenital cardiac abnormalities are described in approximately one third of patients. These abnormalities are mostly left heart obstructions, the most common of which are bicuspid aortic valve (16%) and coarctation of the aorta (11%). Dilatations of the ascending aorta are often described and may occur in isolation from any heart disease, suggesting a vasculopathy specific to the syndrome, probably predisposed to by extracardiac risk factors such as oestrogen deficiency, diabetes, dysplidaemia and overweight. The most feared complication is aortic dissection with around a 100 cases, described at average age of approximately 35-years-old. This is believed to complicate 2% of induced pregnancies. Hypertension (HBP) usually essential, affects up to 50% of patients with Turner's syndrome. This is an important risk factor for cardiovascular complications and justifies aggressive treatment. On the other hand, retrospective studies have not demonstrated adverse cardiological effects due to growth hormone treatments. Patients with Turner's syndrome merit regular cardiology follow-up from childhood onwards, particularly if they have treated heart disease. The merits of preventative treatments for aortic dilatation have not been demonstrated in Turner's syndrome and justify prospective trials.

Abstract
Cardiovascular abnormalities, especially structural congenital heart defects, commonly occur in malformation syndromes and genetic disorders. Individuals with syndromes comprise a significant proportion of those affected with selected congenital heart defects such as complete atrioventricular canal, interrupted arch type B, supravalvar aortic stenosis, and pulmonary stenosis. As these individuals age, they contribute to the growing population of adults with special health care needs. Although most will require longterm cardiology follow-up, primary care providers, geneticists, and other specialists should be aware of (1) the type and frequency of cardiovascular abnormalities, (2) the range of clinical outcomes, and (3) guidelines for prospective management and treatment of potential complications. This article reviews fundamental genetic, cardiac, medical, and reproductive issues associated with common genetic syndromes that are frequently associated with a cardiovascular abnormality. New data are also provided about the cardiac status of adults with a 22q11.2 deletion and with Down syndrome.

Abstract
CONTEXT In Turner syndrome (TS), GH treatment is well established. Data on cardiac status after discontinuation of treatment are scarce. This study aimed to assess biventricular size and function in TS at least 6 months after discontinuation of GH treatment. METHODS TS patients and healthy women prospectively underwent cardiac magnetic resonance imaging. Ventricular two-dimensional tomographic cine data were acquired to obtain biventricular volume, mass, and ejection fraction. Atrioventricular valve flow measurements were performed using a two-dimensional flow-sensitized sequence. Flow velocity curves were calculated and indices of biventricular diastolic filling were derived. RESULTS Thirty-one patients [mean (sd) age 20 (2) yr, body surface area 1.75 (0.15) m(2), 5 (2) yr after GH discontinuation] and 23 normal control women [age 21 (2) yr, body surface area 1.80 (0.13) m(2)] were included. Compared with controls, patients had smaller mean end-diastolic volumes [right ventricle (RV), 84 (11) ml/m(2) vs. 79 (10), P = 0.02; left ventricle (LV), 81 (10) vs. 72 (9), P < 0.001], end-systolic volumes [RV 38 (7) ml/m(2) vs. 36 (6), P = 0.04; LV 34 (5) vs. 29 (4), P < 0.001], and stroke volumes [RV 46 (6) ml/m(2) vs. 43 (6), P = 0.03; LV, 47 (7) vs. 44 (4), P = 0.02]. Patients had a higher mean heart rate [79 (13) beats/min vs. 71 (10), P < 0.05]. Biventricular ejection fraction, mass, cardiac output, and diastolic filling pattern were comparable. CONCLUSION After discontinuation of GH treatment TS patients showed no myocardial hypertrophy and well-preserved biventricular function. Ventricular volumes were smaller in Turner patients, compared with controls, whereas mean heart rate was higher. These last observations may be part of the natural development in TS and not linked to GH treatment, which at this point we consider safe.
