First-trimester assessment of the nasal bone using the retronasal triangle view. A prospective study.
CONCLUSIONS: The RNT view is a useful technique for assessing the NB during the first trimester. With this new approach, performance of absent/hypoplastic NB as a marker of aneuploidy, mainly trisomy 21, appears to be similar to that previously reported by using the midsagittal plane.

Late presentation of simple virilising 21-hydroxylase deficiency in a Chinese woman with Turner's syndrome.
We report on a 66-year-old Chinese, brought up as male, with a simple virilising form of congenital adrenal hyperplasia associated with Turner's syndrome (karyotype 45,X/47,XXX/46,XX). His late presentation was recognised due to his exceptionally short stature and persistent sexual ambiguity. His condition was only brought to medical attention as he developed a huge abdominal mass, which later turned out to be a benign ovarian mucinous cyst. It is therefore important to look out for co-existing congenital adrenal hyperplasia in patients with Turner's syndrome and virilisation, after the presence of Y chromosome material ha...

[Diagnosis and management of amenorrhea in adolescent girls.]
Abstract
Amenorrhea in adolescents can be primary, with or without breast development, or secondary. Whether amenorrhea is primary or secondary, height, body mass index, food intake, the level of physical activity per week, the presence of hirsutism or galactorrhea, pelvic pain and past history of intercourse need to be investigated. Initially, blood tests should include hCG, FSH, estradiol, testosterone and prolactin serum levels. This screening will discriminate between hypogonadotropic hypogonadism and amenorrhea from primary ovarian insufficiency (POI). In case of primary amenorrhea, hypogonadism may be due to ...

Poor socio-economic status in 47,XXX - An unexpected effect of an extra X chromosome.
Abstract
One of the most common sex chromosomal abnormalities in females is 47,XXX syndrome, which is characterized by tall stature and reduced IQ, but with a variable phenotype. In order to elaborate on the characteristics of this syndrome, we undertook an investigation in all diagnosed 47,XXX females at risk in Denmark and compared their socio-economic status with an age-matched cohort of the female background population as well as with all Danes diagnosed with Turner syndrome. We focused on cohabitation, motherhoods, income, education, retirement and convictions. Furthermore, we investigated whether some of thes...

Childhood Lichen Sclerosus—A Challenge for Clinicians
The objective of our study was to define the background and the long‐term course of childhood LS. A registery study identified 44 children with LS treated at Tampere University Hospital, Tampere, Finland, from 1982 to 2010. A questionnaire was sent to the identified patients and 15 responded. The clinical depiction of LS varied significantly. LS was diagnosed in only 16% of the patients at the referring unit. Autoimmune disorders were observed in 6 of the 44 patients. High prevalences of Turner's syndrome (2/44) and kidney disease (2/44) were noted. The majority of the patients were treated with topical corticosteroids. ...

Post-Operative Parsonage Turner Syndrome: A Ghost of Christmas Past? (P01.134)
CONCLUSIONS: PTS can be a difficult syndrome to diagnose. The exact cause is unknown but many factors are thought to influence its development, including trauma, infection, viral disease, heavy exercise, immunization, and autoimmune conditions. We believe that post-operative patients are at risk for developing brachial neuritis. Only two other post-operative PTS caes have been described in the literature but we suspect that many more exist but are not acknowledged due to lack of recognition of this phenomenon. Literature suggests that the stres of surgery may activate an unidentified virus lying dormant in nerve roots. The...

Palatal height and dental arch dimensions in Turner syndrome karyotypes.
Abstract
The aim of this project was to study the impact from Turner syndrome (TS) karyotype and age on dental arch morphology and palatal height and to compare the variables in TS with reference data from non-TS females with normal occlusion. Plaster casts from 76 females with TS (6-50 years) were analysed with respect to dentoalveolar arch dimensions and palatal height. The TS females were divided into the karyotype categories: i) 45,X ii) 45,X/46,XX iii) isochromosome, and iv) other.The 45,X/46,XX karyotype exhibited fewer statistically significant variables differing from the reference group compared with other...

The use of fluorescence in situ hybridization in the diagnosis of hidden mosaicism: apropos of three cases of sex chromosome anomalies
FISH has been used as a complement to classical cytogenetics in the detection of mosaicism in sex chromosome anomalies. The aim of this study is to describe three cases in which the final diagnosis could only be achieved by FISH. Case 1 was an 8-year-old 46,XY girl with normal female genitalia referred to our service because of short stature. FISH analysis of lymphocytes with probes for the X and Y centromeres identified a 45,X/46,X,idic(Y) constitution, and established the diagnosis of Turner syndrome. Case 2 was a 21-month-old 46,XY boy with genital ambiguity (penile hypospadias, right testis, and left streak gonad). FIS...

Implications of parent and child quality of life assessments for decisions about growth hormone treatment in eligible children
ConclusionsDecisions to prescribe GHT should include children's perspectives of HRQL whenever possible. Differences between parents and children are most likely in conditions that involve more complex medical needs (AGHD and Turner's). Generic and disease‐specific HRQL measures may vary in sensitivity to HRQL differences between groups. More work is required to evaluate HRQL among younger children.

An association of craniopharyngioma in turner syndrome
We present three cases of TS with CP, an association not previously described. Visual failure, poor growth or headache led to MRI diagnosis of CP. Whilst two had evidence of hypopituitarism at diagnosis of CP, they all developed hypopituitarism following surgical debulking. Two required radiotherapy due to regrowth. Whether CP and TS share a similar aetiology is unknown. Clinicians need to be aware of this association, and should perform urgent MRI scanning in TS patients with headache, visual impairment or clinical/biochemical evidence of hypopituitarism.

Assessing and addressing cardiovascular risk in adults with Turner Syndrome
Abstract
Turner Syndrome (TS), the result of a structurally abnormal or absent X chromosome, occurs in one in 2000 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 i...

SRY mutation analysis by next generation (deep) sequencing in a cohort of chromosomal Disorders of Sex Development (DSD) patients with a mosaic karyotype
Background:
The presence of the Y-chromosome or Y chromosome-derived material is seen in 4-60% of Turner syndrome patients (Chromosomal Disorders of Sex Development (DSD)). DSD patients with specific Y-chromosomal material in their karyotype, the GonadoBlastoma on the Y-chromosome (GBY) region, have an increased risk of developing type II germ cell tumors/cancer (GCC), most likely related to TSPY. The Sex determining Region on the Y gene (SRY) is located on the short arm of the Y-chromosome and is the crucial switch that initiates testis determination and subsequent male development. Mutations in this gene are responsible ...

Long-term effects of previous Oxandrolone treatment in adult women with Turner syndrome.
CONCLUSION Ox 0.03 mg/kg/day has a beneficial effect on adult height gain in TS patients. Despite previously reported deceleration of breast development during Ox 0.03 treatment, adult breast size is not affected. Mild virilisation persists in only a small minority of the patients. The long-term evaluation indicates that Ox 0.03 treatment is effective and safe.

Liver test abnormalities are frequent in adult patients with Turner syndrome, corresponding to various pathophysiological mechanisms. Steatosis, steatofibrosis and steatohepatitis are the most frequently reported lesions, caused by metabolic disorders, which are commonly related to overweight. Marked architectural changes, including nodular regenerative hyperplasia, multiple focal nodular hyperplasia and cirrhosis, found in some patients, are associated with a risk of severe liver‐related complications. Architectural changes are often observed and are associated with vascular disorders caused by congenitally abn...

Moderate Aortic Enlargement and Bicuspid Aortic Valve are Associated with Aortic Dissection in Turner Syndrome: Report of the International Turner Syndrome Aortic Dissection Registry.
CONCLUSIONS: Aortic dissection in TS occurs in young individuals at smaller aortic diameters than the general population or other forms of genetically triggered aortopathy. The absence of aortic valve or other cardiac malformations appears to markedly reduce the risk of aortic dissection However, aortic dissection can occur in TS without cardiac malformations or hypertension. TS individuals > 18 years with an ASI-AAO above 2.5 cm/m(2) should be considered for an aortic operation to prevent aortic dissection.

Undetected sex chromosome aneuploidy by chromosomal microarray
We report on a case of a female fetus found to be mosaic for Turner syndrome (45,X) and trisomy X (47,XXX). Chromosomal microarray analysis (CMA) failed to detect the aneuploidy because of a normal average dosage of the X chromosome. This case represents an unusual instance in which CMA may not detect chromosomal aberrations. Such a possibility should be taken into consideration in similar cases where CMA is used in a clinical setting. © 2012 John Wiley & Sons, Ltd. (Source: Prenatal Diagnosis)

Reproductive medicine and Turner syndrome: ethical issues
This article discusses the ethical issues raised by the medical responses to Turner syndrome (TS). It explores the issues and challenges faced by women with Turner, and by prospective parents of a child with Turner. It focuses on four issues: the use of GH to increase height; the use of third-party oocytes to enable women with Turner to become pregnant; the parental decision to remove and cryopreserve ovarian tissue from a child with Turner; and the termination of fetuses diagnosed with Turner. Many of the challenges associated with TS are directly or indirectly related to social attitudes and practices, from harsh teasing...

Fertility, pregnancy, and medical management of Turner syndrome in the reproductive years
Turner syndrome results in infertility in most cases. Fertility preservation through the cryopreservation of oocytes or ovarian tissue may be an option for some girls with Turner syndrome. Oocyte donation results in high pregnancy rates (PR). Those women who plan to pursue pregnancy need comprehensive screening and counseling before and after conception. Pregnancies conceived with either autologous or donated oocytes are at high risk of maternal death from aortic dissection/rupture and are at high risk of serious hypertensive disorders. Reproductive age women with Turner syndrome require ongoing screening for associated me...

Genetic considerations in the patient with Turner syndrome—45,X with or without mosaicism
Turner syndrome (TS) is a complex developmental disorder in individuals with short stature who possess a 45,X cell line, with or without mosaicism. Because the single X chromosome is maternally derived in 80% of patients, the genesis of the 45,X karyotype is due to instability of the Y chromosome leading to its loss during meiosis. Phenotypic features vary depending on the mode of ascertainment, with postnatal presentation usually generating a more severe phenotype than a prenatal one. Although patients with pure 45,X present with delayed puberty more often than those with mosaicism for 46,XX or 47,XXX cell lines, the chro...

Ontogenetic changes of craniofacial complex in Turner syndrome patients treated with growth hormone
Conclusions In TS patients treated with GH, growth capacities of cranial base and maxilla are adequate which can be attributed to GH treatment.
Shape of mandible is altered due to decreased growth of corpus and overdeveloped ramus. Both maxillary and mandibular retrognathism
are becoming more expressed during development.
Clinical relevance Favorable influence of GH on craniofacial complex growth rate and altered growth pattern revealed in this study should be
considered while planning both orthodontic treatment and retention.
