    Turner syndrome has multiple comorbidities such as osteoporosis, obesity, diabetes, hypothyroidism, and hypertension. As they are treatable conditions in Turner syndrome, early recognition and proper treatment should be needed. We report on a 23-year-old woman with Turner syndrome who presented with severe osteoporosis and hypercalcemia. Laboratory tests showed elevated levels of serum calcium and parathyroid hormone. Dual-energy X-ray absorptiometry showed severe osteopo-rosis (z score, -3.5). Ultrasound and 99mTc scintigraphy of parathyroid glands showed an adenoma in the right inferior gland. She was diagnosed with primary hyperparathyroidism due to an adenoma of the parathyroid gland. After excision of the adenoma, the patient's serum calcium and parathyroid hormone levels returned to normal. Although only a few cases of Turners syndrome with primary hyperparathyroidism have been reported, hyperparathyroidism should be considered in cases of Turner syndrome with severe osteoporosis and hypercalcemia.

    Parsonage-Turner Syndrome (PTS), also referred to as idiopathic brachial plexopathy or neuralgic amyotrophy, is a rare disorder consisting of a complex constellation of symptoms with abrupt onset of shoulder pain, usually unilaterally, followed by progressive neurologic deficits of motor weakness, dysesthesias, and numbness. Although the etiology of the syndrome is unclear, it is reported in various clinical situations, including postoperatively, postinfectious, posttraumatic, and postvaccination. The identification of the syndrome in the postoperative patient remains a challenge as symptoms may easily be attributed to sequelae of surgical positioning, postoperative recovery, or postanesthetic block pain. The purpose of this review is to bring forth salient, identifiable factors which may assist the surgical clinician in identifying the condition sooner. An early and proper diagnosis affords the opportunity to treat the patient accordingly and to the satisfaction of both surgeon and patient. PMID:21886536

    In Turner syndrome, linear growth is less than the general population. Consequently, to assess stature in Turner syndrome, condition-specific comparators have been employed. Similar reference curves for cardiac structures in Turner syndrome are currently unavailable. Accurate assessment of the aorta is particularly critical in Turner syndrome because aortic dissection and rupture occur more frequently than in the general population. Furthermore, comparisons to references calculated from the taller general population with the shorter Turner syndrome population can lead to over-estimation of aortic size causing stigmatization, medicalization, and potentially over-treatment. We used echocardiography to measure aortic diameters at eight levels of the thoracic aorta in 481 healthy girls and women with Turner syndrome who ranged in age from two to seventy years. Univariate and multivariate linear regression analyses were performed to assess the influence of karyotype, age, body mass index, bicuspid aortic valve, blood pressure, history of renal disease, thyroid disease, or growth hormone therapy. Because only bicuspid aortic valve was found to independently affect aortic size, subjects with bicuspid aortic valve were excluded from the analysis. Regression equations for aortic diameters were calculated and Z-scores corresponding to 1, 2, and 3 standard deviations from the mean were plotted against body surface area. The information presented here will allow clinicians and other caregivers to calculate aortic Z-scores using a Turner-based reference population. © 2015 Wiley Periodicals, Inc. PMID:26118429

    Turner syndrome (TS) is one of the most common sex chromosome abnormalities and results from total or partial monosomy of the X chromosome. It occurs in 1 in 2000 newborn girls and is also believed to be present in a larger proportion of conceptuses. There are various anatomic anomalies that have been associated with TS and the consequences of late recognition of these anomalies can be devastating. Aortic dilation and dissection occur at increased rates in TS patients and contribute to the decreased life expectancy of these patients. Such cases have prompted the need for early identification and continuous monitoring. Other anatomic variations increase morbidity in this population, and negatively impact the social and reproductive aspects of their lives. In this review, we summarize the cardiovascular, neurological, genitourinary, otolaryngolical, craniofacial, and skeletal defects associated with TS. To elucidate these morphological variations, novel illustrations have also been constructed. Clin. Anat. 29:638-642, 2016. © 2016 Wiley Periodicals, Inc. PMID:27087450

    Turner Syndrome (TS) is a common genetic disorder, affecting female individuals, resulting from the partial or complete absence of one sex chromosome, and occurring in approximately 50 per 100,000 liveborn girls. TS is associated with reduced adult height and with gonadal dysgenesis, leading to insufficient circulating levels of female sex steroids and to infertility. Morbidity and mortality are increased in TS but average intellectual performance is within the normal range. TS is closely associated to the presence of autoantibodies and autoimmune diseases (AID), especially autoimmune thyroiditis and inflammatory bowel disease. Despite the fact that the strong association between TS and AID is well known and has been widely studied, the underlying immunopathogenic mechanism remains partially unexplained. Recent studies have displayed how TS patients do not show an excess of immunogenic risk markers. This is evocative for a higher responsibility of X-chromosome abnormalities in the development of AID, and particularly of X-genes involved in immune response. For instance, the long arm of the X chromosome hosts a MHC-locus, so the loss of that region may lead to a deficiency in immune regulation. Currently no firm guidelines for diagnosis exist. In conclusion, TS is a condition associated with a number of autoimmune manifestations. Individuals with TS need life-long medical attention. As a consequence of these findings, early diagnosis and regular screening for potential associated autoimmune conditions are essential in the medical follow-up of TS patients. PMID:22154619

    There is increasing interest in fertility and use of assisted reproductive technologies for women with Turner syndrome (TS). Current parenting options include adoption, surrogacy, and spontaneous and assisted reproduction. For women with TS, specific risks of pregnancy include higher than usual rates of spontaneous abortion, foetal anomaly, maternal morbidity and mortality. Heterologous fertility assistance using oocytes from related or unrelated donors is an established technique for women with TS. Homologous fertility preservation includes cryopreservation of the patient's own gametes prior to the progressive ovarian atresia known to occur: preserving either mature oocytes or ovarian tissue containing primordial follicles. Mature oocyte cryopreservation requires ovarian stimulation and can be performed only in postpubertal individuals, when few women with TS have viable oocytes. Ovarian tissue cryopreservation, however, can be performed in younger girls prior to ovarian atresia - over 30 pregnancies have resulted using this technique, however, none in women with TS. We recommend consideration of homologous fertility preservation techniques in children only within specialized centres, with informed consent using protocols approved by a research or clinical ethics board. It is essential that further research is performed to improve maternal and foetal outcomes for women with TS. PMID:23844676

    Turner's syndrome is a common disorder which occurs in around 1/3000 live births in girls. Diagnostic use of polymorphic DNA markers for the X chromosome could help to reduce the number of time consuming karyotype analyses needed. The M27 beta probe maps on the X chromosome to Xcen-Xp11-22 and in 83% of female subjects detects heterozygosity with multiallelic polymorphism. In Southern blotting, a single X chromosome yields a single hybridisation band. In this study, genomic DNA was extracted from leucocytes of 49 patients with Turner's syndrome (karyotypes: 45,XO, n = 29; 45,XO/46,XX, n = 4; 46,Xi(Xq), n = 1; 45,XO/46,Xi(Xq), n = 4; 45,XO/46,Xr(X), n = 4; 45,XO/46,XY, n = 4; 46,XXp-, n = 3), digested with EcoRI or HindIII, and analysed by Southern blotting. The molecular data for each patient were compared with DNA controls (homozygous 46,XX, heterozygous 46,XX and 46,XY DNA). A single band of reduced intensity compared to homozygous 46,XX control DNA was seen in 41 cases. Two hybridisation bands of different intensities were seen in four patients, in one of whom mosaicism was suspected on the basis of molecular analysis, despite a 45,XO karyotype. In four cases, Turner's syndrome failed to be detected: one 45,XO/46,XX mosaicism with only 4% of 45,XO cells and three distal Xp deletions. DNA analysis appears to be a useful and rapid tool in screening for Turner's syndrome and could be an alternative to cytogenetic analysis in diagnosing the disorder when severe growth retardation or delayed puberty are not accompanied by a Turner phenotype.

    Turner syndrome is one of the most common chromosomal abnormalities affecting female infants. The severity of clinical manifestations varies and it affects multiple organ systems. Women with Turner syndrome have a 3-fold increase in mortality, which becomes even more pronounced in pregnancy. Reproductive options include adoption or surrogacy, assisted reproductive techniques, and in rare cases spontaneous pregnancy. Risks for women with Turner syndrome during pregnancy include aortic disorders, hepatic disease, thyroid disease, type 2 diabetes, and cesarean section delivery. Providers must be familiar with the risks and recommendations in caring for women with Turner syndrome of reproductive age. PMID:26568488

    Congenital and acquired cardiovascular diseases contribute significantly to the threefold elevated risk of premature death in Turner syndrome. A multitude of cardiovascular anomalies and disorders, many of which deleteriously impact morbidity and mortality, is frequently left undetected and untreated because of poor adherence to screening programmes and complex clinical presentations. Imaging is essential for timely and effective primary and secondary disease prophylaxis that may alleviate the severe impact of cardiovascular disease in Turner syndrome. This review illustrates how cardiovascular disease in Turner syndrome manifests in a complex manner that ranges in severity from incidental findings to potentially fatal anomalies. Recommendations regarding the use of imaging for screening and surveillance of cardiovascular disease in Turner syndrome are made, emphasising the key role of non-invasive and invasive cardiovascular imaging to the management of all patients with Turner syndrome.

    Turner syndrome is a common genetic disorder that has been classically associated with a 45,X karyotype. Several X-chromosomal abnormalities have been identified in these patients, many of which involve mosaicism. These patients have variable but predictable phenotypic findings and are at risk for development of endocrine, autoimmune, and structural abnormalities. As many as 1.5% of the population with Turner syndrome may develop dissection and rupture of the ascending aorta; the presence of abnormalities of the cardiac tree and hypertension increase this risk, but their absence does not preclude it. Rupture has occurred at aortic diameters smaller than previously reported for other patient populations. Five percent or more of women with Turner syndrome may have abbreviated menstrual function before developing amenorrhea and hypergonadotropic hypogonadism. An estimated 1 to 2% of all patients may become pregnant. Only three patients with Turner syndrome (and two of them with streak ovaries) have ever been reported to become pregnant after developing amenorrhea and elevated gonadotropin levels. Pregnancy, either spontaneous or more commonly from donor oocyte, increases maternal mortality rate for these women by an estimated ≥100 fold. It appears that all Turner women are at risk of rupture; neither prior spontaneous menses nor age >30 years provides protection. In addition, the literature suggests that the physiological changes of pregnancy may increase the risk of rupture in future years after delivery for those Turner women who seemingly made it safely through pregnancy. The use of the term PRIMARY OVARIAN INSUFFICIENCY (POI) for Turner syndrome gives me some discomfort. For women with 46,XX hypergonadotropic hypogonadism, POI accurately provides the suggestion that follicular depletion is often not complete (although remissions are usually self-limiting and the vast majority of patients will not spontaneously become pregnant). I clearly understand the need to

    Parsonage-Turner syndrome (PTS) is a rare disorder typically characterized by an abrupt onset of upper extremity pain followed by progressive neurologic deficits, including weakness, atrophy, and occasionally sensory abnormalities. The exact cause and pathophysiology of PTS are complex and incompletely understood. Autoimmune, genetic, infectious, and mechanical processes have all been implicated. No specific treatments have been proven to reduce neurologic impairment or improve the prognosis of PTS. Most patients with PTS are treated with a multidisciplinary approach that includes both physical therapy and pharmacologic treatment, often with multiple agents. Further research is needed.

    Premature ovarian insufficiency is a relatively rare condition that can appear early in life. In a non-negligible number of cases the ovarian dysfunction results from genetic diseases. Turner syndrome (TS), the most common sex chromosome abnormality in females, is associated with an inevitable premature exhaustion of the follicular stockpile. The possible or probable infertility is a major concern for TS patients and their parents, and physicians are often asked about possible options to preserve fertility. Unfortunately, there are no recommendations on fertility preservation in this group. The severely reduced follicle pool even during prepubertal life represents the major limit for fertility preservation and is the root of numerous questions regarding the competence of gametes or ovarian tissue crybanked. In addition, patients suffering from TS show higher than usual rates of spontaneous abortion, fetal anomaly, and maternal morbidity and mortality, which should be considered at the time of fertility preservation and before reutilization of the cryopreserved gametes. Apart from fulfillment of the desire of becoming genetic parents, TS patients may be potential candidates for egg donation, gestational surrogacy, and adoption. The present review discusses the different options for preserving female fertility in TS and the ethical questions raised by these approaches. PMID:26677790

    Objective To evaluate uterine development of women with Turner syndrome (TS) receiving conventional medical care. Study design In a cross sectional study we used ultrasound for uterine evaluation in 86 women with TS aged 18–45 years participating in an intramural NIH study, and who had abnormal karyotypes in >70% of white blood cells. Outcomes were uterine dimensions and shape. Information on hormone treatment was obtained by personal interview. Results Twenty five percent had a mature in size and shape uterus, and 31% had an immature uterus, with the remainder in a transitional category. Twenty percent of all participants were not taking hormone replacement (HRT) in the preceding year. The majority on treatment were taking conjugated estrogens or oral contraceptives. Factors associated with uterine maturity were history of spontaneous puberty, and duration and type of HRT, with estradiol based treatment being the most effective. The age at starting HRT was not a critical factor. Conclusions Women with TS may develop a normal uterus even at a late start of HRT given adequate duration of treatment and regardless of karyotype.

    AIMS/BACKGROUND—Females with Turner syndrome commonly exhibit ophthalmological abnormalities, although there is little information in the literature documenting findings specific to Turner syndrome mosaics. Ophthalmic findings are described in four patients with mosaic Turner syndrome. All had anterior chamber abnormalities and all four had karyotypic abnormalities with a 45, X cell line. The possible relation between the karyotypic and the phenotypic findings in these patients is discussed.
METHODS—Four girls with mosaic Turner syndrome underwent a full ophthalmological assessment, including examination under anaesthesia where indicated.
RESULTS—Three of the four patients presented with congenital glaucoma. Two had the karyotype 45, X/46, X, idic(Y) and one a 45, X/47, XXX karyotype. The remaining child had a Rieger malformation of the iris and the karyotype 45, X/46, X, r(X).
CONCLUSIONS—These findings suggest that Turner syndrome mosaicism (where there are two abnormal cell lines) is associated with anterior segment dysgenesis. The findings in these four patients are compared with those seen in other mosaic phenotypes and it is postulated that the presence of two or more genetically different cell lines may have an adverse effect on anterior segment development.

    Turner's syndrome, the most common sex chromosome disorder of females, is caused by complete or partial loss of one X chromosome and is associated with a wide range of internal and external manifestations and increased mortality rates (three to nine times the background population). While individuals with Turner's syndrome may survive for many decades, premature and unexpected deaths can occur that bring decedents to the attention of forensic examiners. Causes of death in Turner's syndrome are often linked to underlying cardiovascular conditions such as aortic dissection, congenital cardiovascular disease, ischemic heart, and cerebrovascular disease, but deaths due to noncardiac causes also occur with increased frequency. The latter include epilepsy, diabetes mellitus, chronic renal disease, pneumonia, chronic liver disease, and malignancy. Thus, the autopsy evaluation of these cases requires careful examination of all major organ systems, with the consideration of confirmatory cytogenetic testing. PMID:24313855

    Girls and women with Turner's syndrome who come to medical attention older than 12 years present a challenge of medical management. Puberty is already delayed and some compromises have to be made in adjusting the timing of artificially induced puberty to optimise overall outcome with respect to stature, secondary sex characteristics, and psychosocial endpoints. Additionally, individuals who present with primary amenorrhoea to adult services might miss the opportunity for effective growth hormone treatment. Further, induction of puberty regimens lack an evidence base or even clear guidelines for the timing and dose of oestrogen replacement. We have searched the scientific literature to inform management of Turner's syndrome. PMID:24703051

    OBJECTIVE--To study prevalence of Turner's syndrome in Denmark and to assess validity of prenatal diagnosis. DESIGN--Study of data on prenatal and postnatal Turner's syndrome in Danish Cytogenetic Central Register. SUBJECTS--All registered Turner's syndrome karyotypes (100 prenatal cases and 215 postnatal cases) during 1970-93. MAIN OUTCOME MEASURES--Prevalence of Turner's syndrome karyotypes among prenatally tested fetuses and Turner's syndrome among liveborn infants. RESULTS--Among infant girls, prevalence of Turner's syndrome was 32/100,000. Among female fetuses tested by amniocentesis, prevalence of Turner's syndrome karyotypes was 176/100,000 (relative risk of syndrome, 6.74 compared with prevalence among untested pregnancies). Among female fetuses tested by chorion villus sampling, prevalence of syndrome karyotypes was 392/100,000 (relative risk, 16.8). We excluded prenatal tests referred because of results of ultrasound scanning: among fetuses tested by amniocentesis revised relative risk was 5.68, while revised relative risk among fetuses tested by chorion villus sampling was 13.3. For 29 fetuses with prenatal diagnosis of possible Turner's syndrome, pregnancy was allowed to continue and 24 children were live born. Thirteen of these children were karyotyped postnatally, and diagnosis of Turner's syndrome had to be revised for eight, seven being normal girls and one boy. This gives tentative predictive value of amniocentesis in diagnosing Turner's syndrome of between 21% and 67%. There was no significant relation between mother's age and risk of Turner's syndrome. CONCLUSIONS--Discrepancy between prenatal and postnatal prevalence of Turner's syndrome challenges specificity of prenatal examination in diagnosing Turner's syndrome. PMID:8555850

    Turner syndrome is a common genetic disorder with an incidence of 1 in 2500 live births. Spontaneous fertility is rare in such patients and is most likely in women with mosaicism or very distal Xp deletions. The authors report an unusual case of familial Turner syndrome in a woman with mosaicism 45,X/46,Xdel(Xp) karyotype with three documented spontaneous pregnancies, which resulted in two daughters with 46,Xdel(X)(p11.4)mat karyotype and a healthy son. The mother was first diagnosed by the age of 11 and did not receive contraceptive medication, due to information that she would be infertile. Both daughters were referred to an endocrinology unit and are now under growth hormone treatment, and have been growing in the 3rd percentile. This family illustrates the complexity and difficulties in counseling, follow-up and treatment in Turner syndrome, namely referring to a tertiary center, fertility and treatment such as growth hormone and hormonal replacement, due to the heterogeneity of the clinical spectrum.

    There is a well-known association between neurofibromatosis-1 (NF1) and Noonan syndrome-like manifestations, including short stature, short broad neck, and hypertelorism. These anomalies are thought to be due to variable expression of the NF1 gene. We report on two girls with NF1 who were found to have the Ullrich-Turner syndrome. Case 1, a 12-year-old white girl, was followed in a Neurofibromatosis Clinic because of multiple cafe-au-lait spots and a family history of NF1 in her mother and sister. On examination, she had short stature, hypertelorism, and short neck with low posterior hairline. Karyotype was 86% 46,XY/14% 45,X. Case 2, the first child of a woman with NF1, presented at birth with lymphedema of hands and feet and a short broad neck. Karyotype was 45,X. At age 23 months she was short, had epicanthic folds, hypertelorism, narrow palate, right simian crease, 19 cafe-au-lait spots, and axillary freckling. We conclude that chromosome studies should be performed in girls with NF1 who have short stature and Noonan- or Ullrich-Turner-like findings. Dilemmas raised by the dual diagnoses of NF1 and Ullrich-Turner syndrome include potential risks of growth hormone therapy and estrogen replacement therapy. 14 refs., 2 figs.

    Turner syndrome (TS) is a sex chromosome condition that occurs in approximately 1/2500 live female births. Despite the prevalence of this chromosomal condition, the challenges these women face throughout their lives are not fully understood. This qualitative research study aimed to characterize the subjective experiences of individuals with Turner syndrome throughout their lifespan, to investigate their concerns and obstacles, and to offer insight into the strengths and weaknesses of health care delivery, as they perceived them. Ninety-seven girls and women with TS and 21 parents consented to participate in this interview study. Interviews were semi-structured and open-ended in design. Questions sought to elicit responses relating to existing concerns associated with their condition and positive and negative health care experiences. Participants were divided into four age categories (childhood, adolescence, adulthood, and mature adulthood) to facilitate a comparative analysis across the age spectrum. Regardless of age, infertility was the most frequently cited concern followed closely by short stature. Sexual development and function and general health were also viewed as challenges by a number of participants in each age group. Although the relative weight of these four concerns tended to shift based upon the individual’s age and life experiences, all four issues remained significant throughout the lifespan. Enhanced awareness of the evolving physical and psychological challenges faced by girls and women with TS may help health care providers improve the quality of life for these individuals.

    Turner syndrome is diagnosed by the combination of certain phenotypic characteristics with the absence of one of the X chromosome. This absence may be total or partial, as occurs in isochromosomes Xq. The phenotypic consequences of these depend on two factors: the characteristics of the lost genes and the percentage of cells 45, X in mosaicisms. The clinical features also change with the cytogenetic pattern. Short stature is the most common phenotypic manifestation, as it is due to the haploinsufficiency of the SHOX gene on the short arm of X chromosomes. Thus, when there is isochromosomes on the long arms, short stature is always present. However, the typical features of this syndrome could be absent, and the diagnosis can be delayed. This occurred in our patients, who will not be able to obtain optimum benefits with growth hormone treatment. PMID:25475905

  15. Turner syndrome and genetic polymorphism: a systematic review

    2015-01-01

    Objective: To present the main results of the literature on genetic polymorphisms in Turner syndrome and their association with the clinical signs and the etiology of this chromosomal disorder. Data sources: The review was conducted in the PubMed database without any time limit, using the terms Turner syndrome and genetic polymorphism. A total of 116 articles were found, and based on the established inclusion and exclusion criteria 17 were selected for the review. Data synthesis: The polymorphisms investigated in patients with Turner syndrome were associated with growth deficit, causing short stature, low bone mineral density, autoimmunity and cardiac abnormalities, which are frequently found in patients with Turner syndrome. The role of single nucleotide polymorphisms in the etiology of Turner syndrome, i.e., in chromosomal nondisjunction, was also confirmed. Conclusions: Genetic polymorphisms appear to be associated with Turner syndrome. However, in view of the small number of published studies and their contradictory findings, further studies in different populations are needed in order to clarify the role of genetic variants in the clinical signs and etiology of the Turner syndrome.

  16. The cognitive phenotype of Turner syndrome: Specific learning disabilities.

    PubMed

    Mazzocco, Michèle M M

    2006-10-01

    Global descriptors of the cognitive phenotype of Turner syndrome are well established and are thus commonly referred to. For example, Turner syndrome is a proposed etiology of the nonverbal learning disability - because of reported relative strengths in verbal skills, and relatively weaker nonverbal skills - particularly in arithmetic, select visuospatial skills, and processing speed. This profile is observed throughout and beyond the school age years. Reliance on this gross level description of the cognitive profile (e.g., nonverbal learning disability) may be helpful as a starting point when determining whether an individual with Turner syndrome has educational needs, but it carries limited practical significance when determining the specific nature of these needs. The limitations stem from the fact that the severity of the cognitive profile is highly variable among individuals with Turner syndrome; that the "nonverbal" difficulties are specific rather than widespread; and that any individual with Turner syndrome may also manifest cognitive characteristics independent of Turner syndrome. In view of the increased risk for specific cognitive difficulties, a detailed assessment prior to the onset of formal schooling (or at the time of diagnosis, when diagnosis occurs after 5 years of age) can play an important role in determining school readiness and potential need for educational support among individual girls with Turner syndrome.

  17. Dentofacial morphology in Turner syndrome karyotypes.

    2012-01-01

    The overall aim of this thesis was to study dentofacial morphology in Turner syndrome (TS) versus controls and the influence hereupon from karyotype. One hundred thirty two TS females (5-66 years of age), from Göteborg, Uppsala and Umeå were participating. Cephalometric analysis, cast model analysis concerning palatal height, dental arch morphology and dental crown width were performed. Eighteen primary teeth were analysed in polarized light microscopy, scanning electron microscopy, microradiography and X-ray microanalysis were performed. The TS females were divided according to karyotype into: 1 45,X; 2 45,X/46,XX; 3 isochromosome; 4 other. Compared to healthy females, TS were found to have a flattened cranial base as well as small and retrognathic jaws with a posterior inclination. The maxillary dentoalveolar arch was narrower and longer, while the mandibular dental arch was wider and longer in TS compared to controls. The palatal height did not differ comparing TS and healthy females. The dental crown width was smaller in TS for both permanent and primary teeth. Aberrant elemental composition, prism pattern and lower mineral density were found in TS primary enamel compared to enamel in primary teeth from healthy girls. Turner syndrome karyotype was found having an impact on craniofacial morphology, with the mosaic 45,X/46,XX exhibiting a milder mandibular retrognathism as well as fewer cephalometric variables differing from controls compared to other karyotypes. Also for the dentoalveolar arch morphology the 45,X/46,XX group had fewer variables differing from healthy females. The isochromosome TS group exhibited the smallest dental crown width for several teeth, while 45,X/46,XX hade the largest dental crown with for some teeth and fewer teeth than both 45,X and isochromosomes that differed from controls. Thus, the mosaic 45,X/46,XX seemed to exhibit a milder phenotype, possibly due to presence of healthy 46,XX cell lines. PMID:22834215

    Turner's syndrome is a disorder defined by an absent or structurally abnormal second X chromosome and affects around 1 in 2000 newborn females. The standardised mortality ratio in Turner's syndrome is around three-times higher than in the general female population, mainly as a result of cardiovascular disorders. Most striking is the early age at which Turner's syndrome patients develop the life-threatening complications of cardiovascular disorders compared to the general population. The cardiovascular risk stratification in Turner's syndrome is challenging and imaging is not systematically used. The aim of this article is to review cardiovascular risks in this group of patients and discuss a systematic imaging approach for early identification of cardiovascular disorders in these patients.

    Three young girls of short stature and with somatic anomalies typical for the Shereshevsky-Turner syndrome are described. Signs of sexual maturation and menarche appeared on time. Later on, menstrual periods came to resemble juvenile bleedings. Karyotypes determined in lymphocyte culture were 45,X/46,XX/47,XXX; 45,X/46,XXp-; and 46,XXp-, respectively. A possibility of spontaneous sexual maturation in patients with the Shereshevsky-Turner syndrome is discussed. PMID:535888

    Dermatological complications in Turner syndrome are infrequent but occasionally cause significant morbidity. Lichen sclerosus (LS) is a chronic inflammatory mucocutaneous affection characterized by pruritus in the anogenital area. It is yet not clear its pathophysiology but it's linked with genetic factors and autoimmunity. This is a case report of a girl with Turner syndrome with growth hormone treatment that started with vulvar pruritus and was diagnosed as lichen sclerosus. PMID:24955917

    Turner syndrome is associated with spatial and numerical cognitive impairments. We hypothesized that these nonverbal cognitive impairments result from limits in spatial and temporal processing, particularly as it affects attention. To examine spatiotemporal attention in girls with Turner syndrome versus typically developing controls, we used a multiple object tracking task during functional magnetic resonance (fMRI) imaging. Participants actively tracked a target among six distracters or passively viewed the animations. Neural activation in girls with Turner syndrome during object tracking overlapped with but was dissimilar to the canonical frontoparietal network evident in typically developing controls and included greater limbic activity. Task performance and atypical functional activation indicate anomalous development of cortical and subcortical temporal and spatial processing circuits in girls with Turner syndrome. PMID:20441384

    Twenty-two cases with Turner syndrome features were subjected to standard cytogenetic techniques using giemsa trypsin (GTG-) banding then fluorescence in situ hybridization (FISH) using a specific whole-X chromosome painting probe, Quint-Essential Y-specific DNA probe (AMELY) for Yp11.2, alpha-satellite (DYZ3) probe and X/Y cocktail-alpha satellite probe (ONCOR) for confirmation of the initial diagnosis and comparison of the two techniques. Eight cases (36%) showed the same karyotype results by both techniques [5 cases: 45,X/46,XX, 2 cases: 45,X/46,X,i(Xq) and one case with a triple cell line 45,X/46,XX/47,XXX]. In the other 14 cases (64%) the FISH technique has identified a third cell line in 7 cases (32%), delineated the origin of the marker in 5 cases (23%) to be derivative X and clarified the deletion of the Yp11.2 region in 2 cases (9%) with the 45,X/46,XY karyotype. The application of FISH has highlighted the differences between the initial diagnosis based on the standard cytogenetic technique and the final diagnosis determined by the application of DNA probes specific for the X and Y chromosomes. FISH proved useful in detection of the low frequency cell lines which need analysis of a large number of metaphase spreads by GTG-banding, helped in identifying the nature and the origin of the unknown markers which has an important implication in the development of gonadal tumours and delineated the deletion of the Yp11.2 region in the 45,X/46,XY Turner patients.

    Turner syndrome is a clinically defined phenotype that is characterized by partial or complete X chromosome monosomy. A host of cytogenetic aberrations and mosaicism have been associated with this syndrome. Some individuals, Turner syndrome variants, have cytogenetic findings consistent with Turner syndrome, but exhibit atypical clinical phenotypes. Recently, several molecular tests have been presented to allow for the refined clinical study of Turner syndrome and its variants. PMID:11216383

    The aim of the study was to assess physical fitness of girls with Turner syndrome (TS) and to determine the relative contributions of age, body height, and body mass to performance in fitness tests. Girls with TS aged 10-18 years (n = 184), and age- and stature-matched healthy controls (n = 280) were studied with the use of the EUROFIT test battery. Girls with TS were significantly inferior to the control group in maintaining balance, standing broad jump, sit-ups, shuttle run, and endurance shuttle run (p < .001). No significant differences were found for plate tapping, but girls with TS were superior to their healthy mates (p < .001) in handgrip, sit-and-reach, and bent-arm hang. Unlike controls, body height in girls with TS had significant effects on handgrip strength (positive) and on plate tapping speed (negative), other contributions being relatively similar in both groups. It thus seems that the somatic specificity of girls with TS explains most differences in motor fitness. The identified motor deficiencies of girls with TS call for undertaking steps toward attracting those girls to motor activities. PMID:23406704

    2015-09-01

    Turner syndrome (TS) is a chromosomal condition affecting an estimated 1 in 2,500 girls where the second X chromosome is missing, or partially formed. This abnormality affects multiple body systems and can lead to short stature, cardiac, neural, and renal abnormalities. Due to the chronic, non-life threatening nature of lymphedema in comparison to other symptoms of TS, it is often ignored by girls and women with TS and their physicians. Consequently, little is known about how lymphedema affects girls and women with TS across the lifespan. Therefore, the objective of the study was to deliver an online survey for females with TS and caregivers in the US, UK, and Canada to provide a worldwide perspective on their current experience with lymphedema within the spectrum of TS. There were 219 participants who completed the survey, and we were able to identify incidence and characteristics of lymphedema across the lifespan. In addition, we found that females with 45,X karyotyping were more likely to report lymphedema symptoms. Lymphedema is not the most significant concern of females with TS, but education, physician evaluation, and assistance with referrals for treatment and management would improve the ease of managing lymphedema in girls and women with TS.

    Turner syndrome (TS) is a chromosomal condition associated with partial or complete absence of the X chromosome that involves characteristic findings in multiple organ systems. In addition to well-known clinical characteristics such as short stature and gonadal failure, TS is also associated with T cell immune alterations and chronic otitis media, suggestive of a possible immune deficiency. Recently, ubiquitously transcribed tetratricopeptide repeat on the X chromosome (UTX), a histone H3 lysine 27 (H3K27) demethylase, has been identified as a downregulated gene in TS immune cells. Importantly, UTX is an X-linked gene that escapes X-chromosome inactivation and thus is haploinsufficient in TS. Mice with T cell-specific UTX deficiency have impaired clearance of chronic viral infection due to decreased frequencies of T follicular helper (Tfh) cells, which are critical for B cell antibody generation. In parallel, TS patients have decreased Tfh frequencies in peripheral blood. Together, these findings suggest that haploinsufficiency of the X-linked UTX gene in TS T cells underlies an immune deficit, which may manifest as increased predisposition to chronic otitis media.

    Turner syndrome is a rare genetic disorder, affecting approximately one in 2500 live-born female, due to total or partial absence of the X chromosome. Typical clinical features are short stature and premature ovarian failure and less constantly phenotypic particularities such as congenital malformations, acquired cardiovascular, otological (hearing impairment), autoimmune and metabolic pathologies. The phenotype is highly variable with slight or even normal phenotype. Several studies have shown that growth hormone treatment improves adult height. The possibility of pregnancies after oocyte donation highlights the high risk of these pregnancies requiring a careful follow-up, especially in terms of cardiovascular issues. Although the quality of life seems similar to the normal population, the presence of cardiovascular and otological diseases, and delayed feminisation are associated with an impaired quality of life. Early diagnosis and regular screening for potentials associated complications are essential in the medical follow-up of these patients. The recent publication of recommendations should lead to an optimization and harmonisation of the medical practices and follow-up from paediatric age to adulthood, a lowering morbidity and self-esteem improvement. The interest of ovarian cryopreservation at an early age in these patients is under investigation. PMID:22041596

    Turner syndrome is associated with a higher frequency of heart defects detected prenatally when compared to postnatal reports. The most common heart defects detected prenatally are hypoplastic left heart syndrome and coarctation of the aorta. We report a case involving a fetus at 16 gestational weeks with a septated cystic hygroma located on the neck and head, an interventricular septal mass, a hypoplastic left ventricle due to aortic stenosis, mitral stenosis, and a hypoplastic aortic arch with a karyotype of mos 45, X, [47 cells]/47, XXX [3 cells]. The autopsy findings confirmed our prenatal diagnosis with a final diagnosis of Turner syndrome and congenital cardiac vascular malformation. PMID:20704479

    Turner`s syndrome patients with Y mosaicism face a high risk of developing gonadoblastoma. Cytogenetic analysis can fail to detect rare cells bearing a normal or structurally abnormal Y chromosome (low level Y mosaicism). We screened 53 individuals with Turner`s syndrome for presence of sex-determining region Y (SRY), the testis-specific protein, Y encoded, gene, and the Y centromeric DYZ3 repeat using nested polymerase chain reaction (PCR). Thirty girls (57%) had the 45,X karyotype, determined through standard analysis of blood lymphocytes. The remaining 23 girls (43%) were mosaics and/or had structural abnormalities in 1 X-chromosome. Genomic DNA from blood leukocytes was amplified using 2 rounds of PCR. This method was sensitive enough to detect 0.0001% male DNA on a female background. None of 53 Turner`s syndrome cases was positive for Y-specific loci after the first round of PCR. After the second round, 2 of 53 Turner`s syndrome cases were positive for SRY mapping to the distal short arm of chromosome Y. In 1 SRY-positive subject, the karyotype was 45,X, and in the other, it was 46,Xi(Xq). None of 53 Turner`s syndrome individuals, including the 2 SRY-positive subjects, were positive for the testis-specific protein, Y encoded, gene on the proximal short arm of chromosome Y or the centromeric DYZ3 repeat. These data exclude low level Y mosaicism in almost all Turner`s syndrome cases tested. 35 refs., 3 figs., 1 tab.

    Turner's syndrome also called as Ullrich Turner's syndrome, is a disease of unclear pathogenesis characterized by complete or partial absence of one sex chromosome, with or without cell line mosaicism in a phenotypic female with short stature. Various anomalies result in a constellation of features, of which the most disturbing is primary amenorrhea due to gonadal dysgenesis. Hormone therapy in these patients can often result in successful menstruation, and scope for subsequent pregnancy because of anatomically normal uterus and vagina. Coexisting Mullerian agenesis in these patients can jeopardize the chances of future pregnancy as they have associated structural abnormalities of the uterus and vagina. We report a rare case of middle-aged female with Turner's syndrome and Mullerian agenesis having absent secondary sexual characters and missing uterus with incompletely formed vagina. PMID:24672170

    Background. Parsonage-Turner syndrome, or neuralgic amyotrophy (NA), is an acute brachial plexus neuritis that typically presents with unilateral shoulder pain and amyotrophy but also can affect other peripheral nerves, including the recurrent laryngeal nerve. Idiopathic vocal fold paralysis (VFP) represents approximately 12% of the VFP cases and recurrence is extremely rare. Methods and Results. We report a man with isolated recurrent unilateral right VFP and a diagnosis of NA years before. Conclusions. We emphasize that shoulder pain and amyotrophy should be inquired in any patient suffering from inexplicable dysphonia, and Parsonage-Turner syndrome should be considered in the differential diagnosis of idiopathic VFP.

    Obstructive lung diseases represent a major health problem worldwide due to their high prevalence associated with elevated socioeconomic costs. Bronchial asthma and chronic obstructive pulmonary disease are chronic obstructive ventilatory disorders with airway inflammation, however they are separate nosological entities based on thedifferent development, diagnostic and therapeutic approaches, and prognostic features. However, these diseases may coexist and can be defined as the coexistence of increased variability of airflow in a patient with incompletely reversible airway obstruction. This phenotype is called asthma - chronic obstructive pulmonary disease overlap syndrome. The syndrome is a clinical and scientific challenge as the majority of these patients have been excluded from the clinical and pharmacological trials, thus well-defined clinical characteristics and therapeutic approaches are lacking. The aim of this review is to summarize the currently available literature focusing on pathophysiological and clinical features, and discuss possible therapeutic approaches of patients with asthma - chronic obstructive pulmonary disease overlap syndrome.

    Objective: Children with Turner syndrome (TS) have a specific growth pattern that is quite different from that of healthy children. Many countries have population-specific growth charts for TS. Considering national and ethnic differences, we undertook this multicenter collaborative study to construct growth charts and reference values for height, weight and body mass index (BMI) from 3 years of age to adulthood for spontaneous growth of Turkish girls with TS. Methods: Cross-sectional height and weight data of 842 patients with TS, younger than 18 years of age and before starting any therapy, were evaluated. Results: The data were processed to calculate the 3rd, 10th, 25th, 50th, 75th, 90th and 97th percentile values for defined ages and to construct growth curves for height-for-age, weight-for-age and BMI-for-age of girls with TS. The growth pattern of TS girls in this series resembled the growth pattern of TS girls in other reports, but there were differences in height between our series and the others. Conclusion: This study provides disease-specific growth charts for Turkish girls with TS. These disease-specific national growth charts will serve to improve the evaluation of growth and its management with growth-promoting therapeutic agents in TS patients. PMID:26831551

    Cytogenetic and DNA analysis in 12 people with stigmata of Turner's syndrome was carried out. Cytogenetic analysis of these patients showed two subjects with 46,X, i(Xq) karyotypes, one with 45,X/46,X, i(Xq), one with 46,X,t(X;Y), and eight with 45,X/46,X,mar. Molecular analysis of DNA samples was performed in nine out of 12 patients with marker chromosomes. PCR analysis with oligoprimers specific for SRY, DYZ1, or DYZ3 loci identified Y chromosome material in five patients in the latter group. The X chromosome origin of the marker chromosome was proved by FISH technique with biotin labelled pericentromeric X chromosome specific probe in four other patients. These results show that patients with a number of Turner's syndrome stigmata usually do not have a typical XO karyotype but have some structural chromosomal aberrations involving the X or Y chromosomes. Combined application of cytogenetic, molecular cytogenetic (FISH), and PCR techniques significantly improves the precision of marker chromosome identification and thus might be of practical importance for the proper management and treatment of affected patients. Peculiarities of pathological manifestations of different karyotypes bearing structural abnormalities of the X or Y chromosomes in patients with Turner's syndrome stigmata, as well as feasible genetic mechanisms of sex determination and differentiation abnormalities in these subjects, are briefly discussed.

    Literature on the complications of burns is abundant. However, there is a paucity of literature on Parsonage-Turner syndrome as a complication of contact burns. The authors described the case of a 27-year-old Chinese man who sustained contact burns on the left upper limb and the left side of the chest wall, presenting sharp intense pain and swelling of the left shoulder deriving from the diagnosis of Parsonage-Turner syndrome. On the basis of clinical findings, the authors selected conservative treatment both for the burns and brachial plexus injury. Approximately 10 days postinjury the patient was able to move his upper limb in the same range as the contralateral uninjured limb. The sensory function recovered and the numbness of the upper limb gradually disappeared. This case shows that Parsonage-Turner syndrome can occur even in second-degree burns with a small total body surface area. Therefore, careful physical examination, early recognition, and prompt treatment are essential for recovery of the injured limb. PMID:24879399

    We present a patient with nonclassic congenital adrenal hyperplasia (NCAH) misdiagnosed as mosaic Turner syndrome. She presented with complaints of primary infertility. Short stature, the presence of facial hair and hoarse voice was also noted. She had primary amenorrhea and was advised for karyotype at 16 years of age, which was reported as 45, X[20]/46, XX[80], stating her as a case of mosaic Turner syndrome. Clitoroplasty was done at 21 years of age for clitoromegaly, which was noticed during puberty. The diagnosis of mosaic Turner could not explain the virilization. Therefore, we repeated the karyotype, which revealed 46, XX in more than 100 metaphases and was sufficient to exclude mosaicism. Furthermore, the endocrinological evaluation revealed high testosterone level with a normal 17 alpha-hydroxyprogesterone (17-OHP). The presence of pubertal onset virilization with a karyotype of 46, XX and raised testosterone level with normal 17-OHP level, raised the suspicion of NCAH for which adrenocorticotropic hormone stimulation test was done which confirmed the diagnosis of NCAH.

    The Ullrich-Turner syndrome (complete or partial X-chromosome monosomy) has been found to be associated with an increased rate of some extragonadal neoplasms. Sporadic reports of the Turner syndrome with various brain tumors, including few cases of glioblastoma multiforme, have been found in the literature. However, published data are insufficient to establish a definite relationship between these tumors and the Turner syndrome. Herein, a rare case of primary pediatric glioblastoma multiforme in a 7-year-old girl with Turner's syndrome is reported, and various aspects regarding clinical and pathophysiological issues have been discussed. Although Turner's syndrome is not one of the congenital chromosomal abnormalities which demand routine CNS screening, neurological assessment may be of value in those with relevant clinical findings.

    We report the case of a 49-years-old patient who presented to the accident and emergency department with sudden onset dyspnea associated with acute shoulder pain. He was breathless at rest with supine hypoxemia. He had an amyotrophic left shoulder with localized paresis of the shoulder. Both hemi-diaphragms were elevated on chest X-rays. Pulmonary function tests showed a restrictive pattern and both phrenic nerve conduction velocities were decreased. At night, alveolar hypoventilation was evidenced by elevated mean capnography (PtcCO2: 57mmHg). Neuralgic amyotrophy, Parsonage-Turner syndrome was the final diagnosis. This syndrome is a brachial plexus neuritis with a predilection for the suprascapular and axillary nerves. Phrenic nerve involvement is rare but where present can be the most prominent clinical feature as in our case report. PMID:25534571

    To determine whether the quantitative and qualitative aspects of GH secretion in girls with Turner's syndrome are similar to those of short-normal children we studied the 24-h GH secretion of 10 patients with Turner's syndrome and 9 short-normal children with comparable auxological features. GH profiles, obtained by 30-min sampling, were analysed by the Pulsar programme. The pulsatile GH release over the 24 h in Turner's syndrome was similar to that in normal children. However, when the GH release over the 12 day and night hours were separately analysed, only normal children showed a night-time increase in the sum of peak amplitudes. Moreover, patients with Turner's syndrome had significantly decreased number and frequency of peaks in the night-time compared with short children. In short-normal children but not in Turner's syndrome, height velocity was related to the 24-h integrated concentration of GH, area under the curve over zero-line and over baseline, sum of peak areas, and amplitudes. Night-time GH area over zero-line and over baseline, mean peak amplitude, height area, sum of peak area and amplitudes were positively correlated with height velocity in short children, whereas in Turner's syndrome height velocity was related to daytime parameters only. In conclusion, girls with Turner's syndrome have a discrete pattern of pulsatile GH release. However, the relation of GH secretion to growth in these patients, is uncertain. PMID:2239077

    Turner syndrome (TS) is caused by an X chromosome aberration and is characterized by endogenous estrogen deficiency secondary to ovarian dysgenesis and short stature. Our aim was to study the prevalence of cardiovascular malformations and cardiovascular risk factors (blood pressure, blood lipids and glucose, coagulation factors, social factors, smoking habits) in adults with Turner syndrome in comparison with a female random population sample. One hundred women with Turner syndrome (aged 16-71 yr) underwent physical examination, echocardiography, electrocardiography, and blood sampling. Seventy-one of them were matched for age [mean age, 33.7 +/- 11 yr (range, 25-64)] with a random population sample (n = 213) of women [mean age, 34.8 +/- 9 yr (range, 25-64)] from the World Health Organization's Monitoring of Trends and Determinants in Cardiovascular Diseases Project, Göteborg. Six percent of Turner syndrome women were smokers compared with 25% in the population (P < 0.001). Turner syndrome women were relatively heavier and had a lower degree of leisure time physical activity than controls (P < 0.001). Diabetes and treatment for hypertension were present in 3 and 22% among Turner syndrome women vs. 2% (not significant) and 3% (P < 0.001) in controls, respectively. Cardiovascular malformations were found among 17% in Turner syndrome women (45,X dominated) vs. 0.5% in controls (P < 0.001). Systolic but not diastolic blood pressure was higher in Turner syndrome women. No differences were seen in serum total cholesterol, high- or low-density lipoprotein cholesterol, triglycerides, lipoprotein (a), or plasma fibrinogen concentrations between patients and controls. Diabetes or hypertension was not related to karyotype. In conclusion, congenital cardiovascular malformations were frequent. Most cardiovascular risk factors (glucose and lipid levels, fibrinogen, smoking habits) were not increased, but hypertension was more common in Turner syndrome women. PMID:11549644

  20. Generalized epilepsy in a patient with mosaic Turner syndrome: a case report

    2014-01-01

    Introduction Reports on cases of epilepsy in Turner syndrome are rare and most of them have cortical developmental malformations. We report the case of a Taiwanese patient with mosaic Turner syndrome with generalized tonic–clonic epilepsy and asymmetrical lateral ventricles but no apparent cortical anomaly. Case presentation A 49-year-old Taiwanese woman without family history presented with infrequent generalized tonic–clonic epilepsy since she was 11 years old. On examination, her short stature, webbed neck, swelling of hands and feet, retrognathic face, and mild intellectual disability were noted. She had spontaneous menarche and regular menses. Brain magnetic resonance imaging showed asymmetrical lateral ventricles and diffuse subcortical white matter T2-weighted hyperintensities. Chromosome studies disclosed low aneuploid (10%) 45,X/46,XX/47,XXX mosaic Turner syndrome. Conclusions There is increasing evidence that epilepsy can be an uncommon presentation of Turner syndrome. Mosaic Turner syndrome with 47, XXX probably increases the risk of epilepsy but more research is needed to reach a conclusion. This case also strengthens our knowledge that Turner syndrome can be one of the pathologic bases of asymmetrical lateral ventricles. When a patient has idiopathic/cryptogenic epilepsy or asymmetrical lateral ventricles on brain images, the presence of a mild Turner phenotype warrants further chromosome studies. PMID:24694237

    Turner syndrome (TS) is a chromosomal disorder of X-monosomy in females. A minority have impaired social responsiveness, poor discrimination of facial emotions (especially fear), and abnormal amygdala-cortical connectivity. We tested the hypothesis that abnormal gaze fixation, especially with the eye region of faces, would be associated with these features, in a similar pattern to that seen in subjects with autism. Furthermore, since these features tend to be more striking in TS women whose X chromosome is maternal in origin, we also predicted that there may be a difference within the Turner's group according to parental origin of the single X. Adults with 45,X karyotype and age and IQ matched 46,XX women were recruited and tested. Facial fear recognition was significantly worse in 45,X females than controls, but there were no group differences according to parental origin of their single X chromosome. Subsequently, we tested 45,X and 46,XX women using a remote eye-tracking device, as they viewed photographs of emotional human faces. Striking differences in scanpaths were found between the TS and controls, and within the TS group, but not according to parental origin of the X chromosome. These findings provide novel evidence for abnormal face processing in some women with TS, and indicate a potential neural mechanism underlying the difficulties in some key aspects of social cognition.

    Turner syndrome (TS) is an important cause of short stature in girls. Patients with TS most often do not have growth hormone deficiency (GHD). Testing GH secretion is not indicated despite the presence of short stature. In the last 20 years only three cases were reported with this association in Pubmed. We describe a case of an 11 year old girl with short stature and karyotype confirmed TS: 45,X(16)46,X,i(X)(ql0)(13). Because her growth velocity was low (-3 SD), we evaluated the GH response with stimulating tests and the results were under the normal range. These findings were compatible with GHD. It is important to check for GHD in patients with TS whenever the growth velocity is low for age and sex. PMID:26540761

    Transition in health care for young patients with Turner's syndrome (TS) should be perceived as a staged but uninterrupted process starting in adolescence and moving into adulthood. As a condition associated with high risk of short stature, cardiovascular diseases, ovarian failure, hearing loss and hypothyroidism, TS requires the attention of a multidisciplinary team. In this review paper, we systematically searched the relevant literature from the last decade to discuss the array of problems faced by TS patients and to outline their optimal management during the time of transfer to adult service. The literature search identified 233 potentially relevant articles of which 114 were analysed. The analysis confirmed that all medical problems present during childhood should also be followed in adult life. Additionally, screening for hypertension, diabetes mellitus, dyslipidaemia, and osteoporosis is needed. After discharge from the paediatric clinic, there is still a long way to go. PMID:24225028

    Turner syndrome is a genetic disorder that can present clinically with multiple concurrent comorbidities. This case report describes a 12-year-old girl with Turner syndrome who was referred for podiatric medical assessment and explores the application of optoelectronic stereophotogrammetry in the biomechanical assessment of the foot and lower limb. A four-segment kinematic foot model using 14-mm reflective markers was applied to the foot and lower limb of the patient to track motion at the tibia, rearfoot, forefoot, and hallux. Kinematic results presented in this case study illustrate evidence of excessive foot pronation throughout the stance phase of gait. Whether excessive pronation is a general characteristic of foot function in Turner syndrome remains to be confirmed, but the findings presented suggest that a comprehensive evaluation of foot biomechanics in patients with Turner syndrome may be warranted.

    Turner syndrome is a sex chromosome aneuploidy with characteristic malformations. Amniotic fluid, a complex biological material, could contribute to the understanding of Turner syndrome pathogenesis. In this pilot study, global gene expression analysis of cell-free RNA in amniotic fluid supernatant was utilized to identify specific genes/organ systems that may play a role in Turner syndrome pathophysiology. Cell-free RNA from amniotic fluid of five mid-trimester Turner syndrome fetuses and five euploid female fetuses matched for gestational age was extracted, amplified, and hybridized onto Affymetrix(®) U133 Plus 2.0 arrays. Significantly differentially regulated genes were identified using paired t tests. Biological interpretation was performed using Ingenuity Pathway Analysis and BioGPS gene expression atlas. There were 470 statistically significantly differentially expressed genes identified. They were widely distributed across the genome. XIST was significantly down-regulated (p < 0.0001); SHOX was not differentially expressed. One of the most highly represented organ systems was the hematologic/immune system, distinguishing the Turner syndrome transcriptome from other aneuploidies we previously studied. Manual curation of the differentially expressed gene list identified genes of possible pathologic significance, including NFATC3, IGFBP5, and LDLR. Transcriptomic differences in the amniotic fluid of Turner syndrome fetuses are due to genome-wide dysregulation. The hematologic/immune system differences may play a role in early-onset autoimmune dysfunction. Other genes identified with possible pathologic significance are associated with cardiac and skeletal systems, which are known to be affected in females with Turner syndrome. The discovery-driven approach described here may be useful in elucidating novel mechanisms of disease in Turner syndrome. PMID:24850140

    Turner's syndrome is associated with autoimmune disorders. Autoimmune endocrinopathy in Turner's syndrome seems to be limited to autoimmune thyroiditis. A small number of patients with Turner's syndrome has also been associated with celiac disease, inflammatory bowel disease and juvenile rheumatoid arthritis. Type 1 diabetes mellitus in Turner's syndrome has been rarely reported. We present here the youngest patient with Turner's syndrome who developed type 1 diabetes mellitus. At the age of 3.5 years she was hospitalized with diabetic ketoacidosis. Anti-islet cell and anti-insulin antibodies were positive and C-peptide level was low. When she was investigated for recurrent urinary tract infections, horseshoe kidney was detected by ultrasonography. Karyotype analysis revealed 45,XO. She has been followed for 2 years with an insulin dose of 0.9 U/kg per day. The prevalence of type 1 diabetes mellitus associated with Turner's syndrome is still unknown. PMID:12387520

  9. Parsonage-Turner syndrome following post-exposure prophylaxis

    2014-01-01

    Background The ‘Parsonage-Turner syndrome’ (PTS) is a rare but distinct disorder with an abrupt onset of shoulder pain, followed by weakness and atrophy of the upper extremity musculature, and a slow recovery requiring months to years. To our best knowledge, this is the first case describing symptoms and signs of PTS following the administration of a post-exposure prophylaxis (PEP) regimen against possible human immunodeficiency virus (HIV) and hepatitis B virus (HBV) infection. Case presentation A 25-year-old Caucasian man presented with pain and unilateral scapular winging following PEP against possible HIV and HBV infection. Although atrophy and weakness were observed for the right supraspinatus muscle, a full range of motion was achievable. Neurological examination, plain radiography of the right shoulder and electromyography showed no additional abnormalities. The patient was diagnosed with post-vaccination PTS and treated non-operatively. During the following 15 months the scapular winging receded and full muscle strength was regained. Conclusion Parsonage-Turner syndrome is a rare clinical diagnosis. The precise pathophysiological mechanism of PTS remains unclear, but it seems to involve an interaction between genetic predisposition, mechanical vulnerability and an autoimmune trigger. An immunological event, such as – in this case – a vaccination as part of PEP treatment, can trigger the onset of PTS. The clinical presentation is distinctive with acute severe pain followed by patchy paresis, atrophy and sensory symptoms that persist for months to years. No currently available tests can provide a definite confirmation or exclusion of PTS. Routine blood examination, electromyography (EMG), and computed tomography (CT) or magnetic resonance imaging (MRI) serve mainly to exclude other disorders. The recovery can be quite lengthy, non-operative treatment is the accepted practice. Supplementary administration of oral prednisolone could shorten the

    Turner syndrome (TS) is one of the most frequently encountered sex-linked chromosomal abnormalities, occurring in one per 2,000 female births. These patients present with short stature and failure to begin puberty. In this syndrome, there are multiple organ abnormalities, including auditory disorders. TS patients were referred to the ENT clinic by a pediatric endocrinologist. A questionnaire was filled out and the patients went through a complete otologic examination. They were then referred to the audiology clinic to undergo audiologic test battery plus high-frequency pure tone audiometry. From a total of 48 ears examined, 11 (22.9 %) had a normal audiometry. Mid-frequency sensorineural hearing loss (SNHL), high-frequency SNHL, combined and mixed hearing loss were diagnosed in 6 (12/5 %), 20 (41/7 %), 6 (12/5 %) and 1 (2/1 %) ear, respectively. Tympanogram results showed normal compliance (A, As, Ad) in the majority of cases. B and C patterns were found in a few cases. Speech discrimination score was normal in all patients whereas speech reception threshold was normal in 92 % of the ears. Audiometry abnormality especially SNHL is common in TS patients, with the high-frequency pattern being the most frequent. PMID:25534285

    Parsonage-Turner syndrome (PTS) is a distinct clinical syndrome, characterized by acute and severe (mostly) unilateral shoulder pain, followed by paresis and atrophy of the shoulder girdle, while the pain decreases. Most authors consider it as an immune-mediated disorder. PTS is notoriously unrecognised and is usually diagnosed with delay. A PTS may also occur following a surgical procedure. Postsurgical PTS is an under-recognised and challenging clinical entity, as illustrated in the case reported here of a 59-year-old man, 4 weeks after anterior discectomy and fusion C5C7. In such cases, the differential diagnosis must be made with a complication of surgery, such as postoperative C5 palsy due for instance to a migrated bone graft. Arguments for PTS are: a certain delay between surgery and symptoms, intolerable pain followed by weakness and improvement of pain complaints, divergent distribution of weakness, sensory deficit and pain, which may be confirmed by electrodiagnosis. Early recognition of postsurgical PTS may avoid unnecessary investigations or surgical exploration. It allows to treat the patient properly, leading to greater satisfaction of both surgeon and patient; pain management, physical therapy and reassurance are the cornerstones. PMID:23547510

    Turner syndrome (TS) is a relatively common chromosomal disorder and is associated with a range of comorbidities involving the cardiovascular system. Vascular abnormalities, in particular, are a common finding in cases of TS. However, dissection involving the vertebral arteries is rare. Here, we report the case of a 9-year-old girl with TS who had been treated with growth hormone replacement therapy for the past 3 years. She presented with weakness of both lower legs, and was ultimately diagnosed with spinal hemorrhage due to vascular malformation. We treated her with intravenous high dose dexamethasone (0.6 mg/kg) and she could walk without assistance after 6 days of treatment. In conclusion, when a patient with TS shows sudden weakness of the lower limbs, we should consider the possibility of spinal vessel rupture and try to take spine magnetic resonance imaging as soon as possible. We suggest a direction how to make a proper diagnosis and management of sudden vertebral artery hemorrhage in patients with TS. PMID:26817012

    Summary Turner syndrome (TS) has been linked to a number of autoimmune conditions, including lichen sclerosus (LS), at an estimated prevalence of 17%. LS is a known precursor to vulvar cancer. We present a case of vulvar cancer in a 44-year-old woman, who had previously complained of pruritus in the area, a known symptom of LS. Histology confirmed a squamous cell carcinoma with underlying LS. Vulvar assessment for the presence of LS should be undertaken regularly as part of the routine assessments proposed for adult TS women. If LS is identified, then the patient should be warned of the increased risk of vulvar cancer progression and should be monitored closely for signs of the condition. Learning points Patients with TS are at increased risk of developing LS.LS is a known precursor to vulvar cancer.TS women with LS may be at risk of developing vulvar cancer and should be offered annual vulvar screening and also be aware of signs and symptoms of early vulvar cancer.

    Mosaicism involving the sex chromosomes is a common finding in women with Turner syndrome (TS). It is especially important to detect Y-chromosomal material, since this is a risk factor for the development of gonadoblastoma. Recent studies have also indicated that the frequency of 45,X cells may be used to predict prognosis. As part of an ongoing multi-disciplinary study, we have examined the extent of Y-chromosomal material and sex chromosomal mosaicism and its tissue specificity in 53 women with TS. The results of lymphocyte karyotyping were compared with the use of interphase X/Y fluorescence in situ hybridisation (FISH) analysis of lymphocytes and buccal mucosal cells. As could be expected, an extended FISH analysis detected more Y-chromosomal material than karyotyping (in 15% vs. 11% of the women, respectively) and also detected more X-chromosomal mosaicism among the TS women (in 70% vs. 45 % of the women, respectively). In half of the women, tissue-specific differences between lymphocytes and buccal mucosal cells were found. Based on these results, we suggest the use of X/Y interphase FISH as a complement to karyotyping in order to obtain a more complete knowledge of the chromosome constitution of each individual with TS.

    Turner syndrome (TS) is a genetic disorder affecting females, resulting from the complete or partial absence of an X chromosome. The cognitive profile of TS shows relative strengths in the verbal domain and weaknesses in the procedural domain, including working memory. Neuroimaging studies have identified differences in the morphology of the parietal lobes, and white matter pathways linking frontal and parietal regions, as well as abnormal activation in dorsal frontal and parietal regions. Taken together these findings suggest that abnormal functional connectivity between frontal and parietal regions may be related to working memory impairments in TS, a hypothesis we tested in the present study. We scanned TS and typically developing participants with functional magnetic resonance imaging while they performed visuospatial and phonological working memory tasks. We generated a seed region in parietal cortex based on structural differences in TS and found that functional connectivity with dorsal frontal regions was reduced during working memory in TS. Finally, we found that connectivity was correlated with task performance in TS. These findings suggest that structural brain abnormalities in TS affect not only regional activity but also the functional interactions between regions and that this has important consequences for behavior.

    Turner's syndrome (TS) affects about 1/2500 female infants born alive. The syndrome results from total or partial absence of one of the two X chromosomes normally present in females. We report the results of a retrospective analysis of 89 cases of TS observed during a six-year period (2000-2005). The patients' age ranged from two days to 51 years at the time of this analysis. Most patients were adults (48%). The aim of this study is to ascertain the principal clinical features leading to a request for a karyotype, searching for a possible relationship between chromosomal anomalies and clinical expression of TS. Pediatric patients were referred for statural retardation or dysmorphic features, while reproduction anomalies were the main indication for karyotyping in patients aged over 20 years. Mosaicism was prevalent (47%), whereas the homogeneous karyotype 45,X was found in only 32% of the patients; structural anomalies were found in 21%. Regarding the advanced age of our patients, we established a relationship between chromosome anomalies and the clinical expression of TS, based on an analysis of stature and reproduction disorders. Short stature and primary amenorrhea were correlated with total deletion of one chromosome X or imbalanced gene dosage due to structural X anomalies. Whereas cases of infertility, recurrent miscarriages and secondary amenorrhea were associated with a mosaic karyotype pattern (45,X/46,XX or 45,X/46,XX/47,XXX ...), with a slight mosaicism in most cases. Thus, chromosome investigations should be performed in cases of reproduction failure even for women with normal stature. PMID:18541220

    Turner syndrome is a complex human phenotype, commonly associated with a 45,X karyotype. Mapping the Turner phenotype is difficult since hidden mosaicisms, partial monosomy and complex rearrangements are present in many affected individuals. In addition, attempts to map the genes involved to the X chromosome have failed to yield a consistent localisation. An alternative approach to map and identify Turner genes is to study XY individuals, with sex chromosome abnormalities, who present with or without characteristic Turner stigmata. We report the analysis of 4 individuals with terminal deletions of Yq. The individuals were azoospermic males without phenotypic abnormalities (2 cases) and azoospermic males presenting with a specific subset of Turner stigmata (2 cases). Breakpoints in each of the cytogenetically detectable Yq deletions were mapped by Southern analysis and Y chromosome-specific sequence tagged sites (STS). Correlation between the patients phenotypes and the extent of their deletion indicate a critical region associated with specific Turner stigmata (cubitus valgus, shield chest, short fourth metacarpals) and growth retardation at Yq at proximal interval 5. These data provide evidence that the somatic features of the Turner syndrome are most likely caused by haploinsufficiency of genes at several loci.

    Turner syndrome is the most common chromosomal disorder in girls. Various phenotypic features show depending upon karyotype from normal female through ambiguous genitalia to male. Usually, Turner girls containing 45,X/46,XY mosaicism, or sex-determining region Y (SRY) gene may have mixed gonadal dysgenesis with various external sexual differentiation. We experienced a short statured 45,X Turner girl with normal external genitalia. Because SRY gene was positive, laparoscopic gonadectomy was performed. The dysgenetic gonads revealed bilateral ovotesticular tissues. The authors report a mixed gonadal dysgenesis case found in clinical 45,X Turner patient with positive SRY gene. Screening for SRY gene should be done even the karyotype is 45,X monosomy and external genitalia is normal. PMID:26817010

    Although abnormal liver function tests occur in 50-80% of cases with Turner syndrome, there are no previous reports of overt hepatic disease or hepatic granulomas associated with Turner's syndrome. We report three cases of Turner syndrome associated with hepatic granulomas with a wide range of liver dysfunction. Of the three patients, first patient underwent liver transplantation; second patient remained stable on immunosuppressants; and third patient died from complications of decompensated liver cirrhosis as she declined liver transplantation due to multiple comorbidities. One patient had sitosterolemia, a rare inherited autosomal recessive disorder of cholesterol metabolism, after she ingested β-sitosterol supplement and had worsening liver function tests and lipid panel. She had remarkably abnormal lipid panel that responded to ezetimibe and by stopping the β-sitosterol supplement. PMID:25705228

    This work aimed at reporting a case of Turner's syndrome with portal vein thrombosis and elevated levels of factor VIII and von Willebrand factor. A 14-year-old Libyan girl was admitted for evaluation of infantilism and pallor; meanwhile, she was found to be of short stature, with webbing of the neck. Chromosomal studies showed monosomy pattern Turner's syndrome (45XO). Abdominal ultrasound displayed a hugely enlarged spleen. Computed tomography (CT) imaging of the abdomen revealed portal vein thrombosis and dilated venous collaterals in porta hepatis. Thrombophilia screening demonstrated elevated levels of factor VIII (207 IU dl(-1)) and von Willebrand factor (450 IU dl(-1)). It was concluded that this was a case report on the unusual finding of portal vein thrombosis in a patient with Turner's syndrome in whom high levels of factor VIII and von Willebrand factor were found. Detailed molecular epidemiological study is recommended to clarify this finding and its underlying factors. PMID:22560822

    Objective To identify and characterize otolaryngologic markers for the early diagnosis of Turner Syndrome (TS). Study Design Prospective cohort survey. Methods Setting Clinical Center of the National Institutes of Health (NIH). Patients Ninety-one females, 7 - 61 years old (average = 28.7 y), enrolled in a multidisciplinary study of karyotype-phenotype correlations in TS. Main Outcome Measures Age at diagnosis, X chromosome karyotype, history of chronic or recurrent otitis media (OM), sensorineural hearing loss (SNHL), palate dysmorphism, pinna deformity, pterygium colli, low posterior hairline, low-set ears, and micrognathia. Results Sixty-nine (76%) patients had a history of chronic or recurrent OM, 62 (68%) had a dysmorphic palate, 57 (63%) had SNHL, and 90 (99%) had one or more of these findings. 83 (91%; average age at diagnosis = 9.4 y) had one or more external craniofacial signs: pinna abnormalities, pterygium colli, low-set ears, micrognathia or a low posterior hairline. Eight patients (average age at diagnosis = 13.2 y) had no external craniofacial signs, although seven (88%) of these eight patients had a history of chronic or recurrent OM, dysmorphic palate or SNHL. The age at diagnosis was not significantly different between groups with or without external craniofacial signs (P = 0.126). Conclusions Patients with mild or incompletely penetrant TS phenotypes often present with otitis media, hearing loss, or both before the diagnosis of TS is established. Palatal dysmorphism, including ogival morphology, is another otolaryngologic marker for TS. Prompt recognition of these manifestations of TS could hasten its diagnosis and appropriate medical care.

    Turner syndrome (TS) is characterized by numerous medical challenges during adolescence and adulthood. Puberty has to be induced in most cases, and female sex hormone replacement therapy (HRT) should continue during adult years. These issues are normally dealt with by the paediatrician, but once a TS female enters adulthood it is less clear who should be the primary care giver. Morbidity and mortality is increased, especially due to the risk of dissection of the aorta and other cardiovascular diseases, as well as the risk of type 2 diabetes, hypertension, osteoporosis, thyroid disease and other diseases. The proper dose of HRT with female sex steroids has not been established, and, likewise, benefits and/or drawbacks from HRT have not been thoroughly evaluated. The transition period from paediatric to adult care seems to be especially vulnerable and the proper framework for transition has not yet been established. Likewise, no framework is in place for continuous follow-up during adult years in many countries. Today, most treatment recommendations are based on expert opinion and are unfortunately not evidence based, although more areas, such as growth hormone and oxandrolone treatment for increasing height, are becoming well founded. Osteoporosis, diabetes, both type 1 and 2, hypothyroidism, obesity and a host of other endocrine diseases and conditions are seen more frequently in TS. Prevention, intervention and proper treatment is only just being recognized. Hypertension is frequent and can be a forerunner of cardiovascular disease. The description of adult life with TS has been broadened and medical, social and psychological aspects are being added at a compelling pace. Proper care during adulthood should be studied and a framework for care should be in place, since most morbidity potentially is amenable to intervention. In summary, TS is a condition associated with a number of diseases and conditions which need the attention of a multi-disciplinary team during

    The aim of this project was to study possible influences of Turner syndrome (TS) karyotype and the number of X chromosomes with intact short arm (p-arm) on dental crown width. Primary and permanent mesio-distal crown width was measured on plaster casts from 112 TS females. The influence on crown width of four karyotypes: 1. monosomy (45,X), 2. mosaic (45,X/46,XX), 3. isochromosome, and 4. other, and the number of intact X chromosomal p-arms were investigated. In comparisons between karyotypes, statistically significant differences were found for isochromosome karyotype maxillary second premolars, canines, laterals, mandibular first premolars, and canines, indicating that this karyotype was the most divergent as shown by the most reduced crown width. When each karyotype group were compared versus controls, all teeth in the isochromosome group were significantly smaller than controls (P < 0.01-0.001). The 45,X/46,XX karyotype expressed fewer and smaller differences from controls, while 45,X individuals seemed to display an intermediate tooth width compared with 45,X/46,XX and isochromosomes. No significant difference in crown width was found comparing the groups with one or two intact X chromosomal p-arms. Both primary and permanent teeth proved to have a significantly smaller crown width in the entire group of TS females compared to healthy females. We conclude that the isochromosome group deviates most from other karyotypes and controls, exhibiting the smallest dental crown width, while individuals with 45,X/46,XX mosaicism seemed to have a less affected crown width. An influence of the number of intact p-arms on crown width could not be demonstrated in this study. PMID:21303812

    In this article we review the existing fertility preservation options for women diagnosed with Turner syndrome and provide practical guidelines for the practitioner. Turner syndrome is the most common sex chromosome abnormality in women, occurring in approximately 1 in 2500 live births. Women with Turner syndrome are at extremely high risk for primary ovarian insufficiency and infertility. Although approximately 70%-80% have no spontaneous pubertal development and 90% experience primary amenorrhea, the remainder might possess a small residual of ovarian follicles at birth or early childhood. The present challenge is to identify these women as early in life as is possible, to allow them to benefit from a variety of existing fertility preservation options. To maximize the benefits of fertility preservation, all women with Turner syndrome should be evaluated by an expert as soon as possible in childhood because the vast majority will have their ovarian reserve depleted before adulthood. Cryopreservation of mature oocytes and embryos is a proven fertility preservation approach, and cryopreservation of ovarian tissue is a promising technique with a growing number of live births, but remains investigational. Oocyte cryopreservation has been performed in children with Turner syndrome as young as 13 years of age and ovarian tissue cryopreservation in affected prepubertal children. However, current efficacy of these approaches is unknown in this cohort. For those who have already lost their ovarian reserve, oocyte or embryo donation and adoption are strategies that allow fulfillment of the desire for parenting. For those with Turner syndrome-related cardiac contraindications to pregnancy, use of gestational surrogacy allows the possibility of biological parenting using their own oocytes. Alternatively, gestational surrogacy can serve to carry pregnancy resulting from the use of donor oocytes or embryos, if needed. PMID:26485320

    Over the past few decades, behavioral, neuroimaging and molecular studies of neurogenetic conditions, such as Williams, fragile X, Turner and velocardiofacial (22q11.2 deletion) syndromes, have led to important insights regarding brain development. These investigations allow researchers to examine "experiments of nature" in which the deletion or alteration of one gene or a contiguous set of genes can be linked to aberrant brain structure or function. Converging evidence across multiple imaging modalities has now begun to highlight the abnormal neural circuitry characterizing many individual neurogenetic syndromes. Furthermore, there has been renewed interest in combining analyses across neurogenetic conditions in order to search for common organizing principles in development. In this review, we highlight converging evidence across syndromes from multiple neuroimaging modalities, with a particular emphasis on functional imaging. In addition, we discuss the commonalities and differences pertaining to selective deficits in visuospatial processing that occur across four neurogenetic syndromes. We suggest avenues for future exploration, with the goal of achieving a deeper understanding of the neural abnormalities in these affected populations. PMID:19376197

    Turner's syndrome is a common genetic disorder of girls and women, for which characteristic clinical symptoms encompass short stature, gonadal dysgenesis, systemic defects, multiple dysmorphic features and skin changes, including an increased number of melanocytic nevi, hypertrophic scars and keloids. The affected girls are treated with recombinant human growth hormone to improve the height. We present a case of a 15-year-old girl with Turner's syndrome, hypertrophic scars and a keloid. At the age of 12 years and 8 months, the girl started recombinant human growth hormone treatment. During the therapy, a surgical excision of 4 out of 42 benign melanocytic nevi was performed. After 2 months the hypertrophic scars as well as a keloid were noted at sites of excision. Parents of girls with Turner's syndrome undertake various attempts to improve not only the height and maturity of their daughters, but also their appearance by commonly performed surgical corrections of the webbed neck and pigmented nevi. The presented case suggests an increased risk of scars hypertrophy and keloid formations after surgical intervention in Turner's syndrome patients who are treated with recombinant human growth hormone at the same time. Due to that it should be advised to postpone all planned surgical procedures until the therapy has been completed. PMID:25097479

  19. Genotype/phenotype correlation in women with nonmosaic X chromosome deletions and Turner syndrome

    SciTech Connect

    Zinn, A.R.

    1994-09-01

    Turner syndrome is a complex human developmental disorder associated with the absence of the second sex chromosome (monosomy X). Cardinal features of the Turner phenotype include high intrauterine lethality, growth retardation, gonadal failure, and the variable presence of specific somatic abnormalities such as webbed neck, lymphedema, and skeletal abnormalities. Recent observations support the hypothesis that the phenotype associated with monosomy X results from haploid dosage of genes common the X and Y chromosomes that escape X-inactivation ({open_quotes}Turner genes{close_quotes}). Apart from a locus causing short stature that maps to the pseudoautosomal region on the distal short arm, the location of X-linked Turner genes is not known. Karyotype/phenotype correlations in women with partial X deletions have been inconsistent. However, previous studies have focused on sporadic sex chromosome aberrations and may have been confounded by occult mosaicism. In addition, mapping of deletions was limited by the resolution of cytogenetic techniques. I am reexamining genotype/phenotype correlations in partial X monosomy, focusing on a subset of cases in which mosaicism is highly unlikely (e.g., unbalanced X-autosome translocations, familial X deletions), and using molecular techniques to map deletions. I have collected eight cases of nonmosaic X deletions in women with varied manifestations of Turner syndrome. Cytogenetic data suggests that genes responsible for Turner anatomic abnormalities may lie within a critical region of the very proximal portion of the short arm (Xp11). Molecular characterization of the deletions is in progress. Methods include (1) fluorescence in situ hybridization of metaphase spreads from patient-derived cell lines, using cosmid probes that map to known locations on Xp, and (2) sequence tagged site (STS) content mapping of somatic cell hybrids retaining the deleted X chromosomes derived from these cell lines.

Only for AIH there is evidence of an autoimmune etiology and humoral and cellular immune reactions are found directed against various liver cell antigens. By diverse autoantibodies several subgroups of autoimmune hepatitis can be distinguished. A very important disease promoting factor seems to be the genetically determined background for autoimmunity characterized by the HLA haplotype A1, B8 and DR3, respectively DR4. Although the histopathology of AIH shows no pathognomonic features distinguishing this type of hepatitis from virus induced chronic hepatitis there are some distinct characteristic morphological lesions. If untreated the prognosis of AIH is unfavourable but the benefit from immunosuppressive therapy with prednisolone and azathioprin is well established. In the last years there was increasing evidence for an overlap syndrome between AIH and PBC and rarely AIH and PSC. These patients are characterized by PBC characteristic bileduct lesions and oftenly antimitochondrial antibodies (AMA). They also show AIH typical inflammatory hepatic lesions in the periportal areas and portal tracts and oftenly the typical genetical background, the HLA haplotype A1, B8, DR3 or DR4. Most of these patients respond probably to a combination therapy containing prednisolon, azathioprine and ursodesoxycholic acid that leads to the reduction of the inflammatory activity.

    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.

    Classical congenital adrenal hyperplasia due to 21-hydroxylase deficiency is a well-known disorder of sexual development (previously known as ambiguous genitalia) in genotypic female neonates. 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 has been excluded.

    Subjects with hypergonadotropic hypogonadism due to Turner's syndrome show low cortical mineral density, osteoporosis and risk of fractures. It is not clear if this bone fragility derives from chromosomal abnormalities or is the result of inadequate bone formation due to estrogen deficiency. The aim of this study was to investigate the cellular mechanisms underlying bone fragility in subjects with Turner's syndrome before induction of puberty and after hormonal replacement therapy (HRT). For this purpose, we have evaluated the osteoclastogenic potential of non-fractioned and T-cell depleted cultures of peripheral blood mononuclear cells (PBMCs) belonging to girls with Turner's syndrome who had not been treated with HRT yet, girls and young women who were on HRT and age-matched controls. Untreated subjects showed high FSH serum levels, whereas the other subjects displayed normal FSH serum levels. T-cell immunophenotype was analyzed through flow cytometry. Biochemical and DXA analyses were performed. Spontaneous osteoclastogenesis in non-fractioned and T-cell depleted cultures of PBMC belonging to girls with high FSH levels was more evident than in cultures of subjects with normal FSH levels. In the former, osteoclastogenesis was sustained by monocytes expressing high levels of c-fms, TNF-α and RANK, and T-cells producing high RANKL and TNF-α; in the latter it was supported by T-cells expressing high RANKL levels. CD4(+)CD25(high) T-cells were reduced in all subjects, whereas CD3(+)/CD16(+)/CD56(+) NKT-cells were increased in those with high FSH levels. High RANKL and CTX levels were detected in the sera. Bone impairment was already detectable by DXA in subjects aged under 10, although it became more evident with aging. In conclusion, our results demonstrated that bone fragility in subjects with Turner's syndrome is associated to enhanced osteoclastogenesis. This process seems to be due to high FSH serum levels before HRT, whereas it is caused by high RANKL during

    Background Turner syndrome is a relatively common chromosomal disorder. The disease affects only females, causing hypogonadism and short stature. Early treatment can improve short stature and hypogonadism. The study aims to describe chromosomal abnormalities, clinical characteristics and its relationship with chromosomal abnormalities in patients with Turner syndrome. Methods A total of 213 patients with Turner syndrome diagnosed in National Hospital of Pediatrics, Hanoi. A cross section study was used. Results Mean age on diagnosis was 12.2±4.9 years. Monosomy 45,XO occupied 54,31%; 45,X/46,XX was seen in 14.66%; 27.59% had structural disorders of chromosome X. Short stature was found in all patients aged more than 15 years. Severity of short stature and percentage of patients with short stature went up with age. There was no difference in term of height between karyotype groups. In group aged ≥12 years, 95.2% of cases had hypogonadism. Other symptoms frequently seen were nail hypoplasia (77.4%), cubitus valgus (74.7%), broad chest (69.2%)/abnormalities in face and neck were epicanthic fold (55.6%), low posterior line (51.3%), excessive skin in the back of the neck/webbed neck (42.5%). In a group aged <1 year, lymphoedema of hands/feet, epicanthic fold, broad chest, cubitus valgus were found in 100%. Majority of symptoms, congenital defects of heart/kidney were seen more frequently in 45,X group. Conclusions Lymphoedema of hands/feet in infants, low growth velocity, delayed puberty, abnormalities in face and neck, and other symptoms should be checked to early diagnose and treat Turner syndrome. Patients with 45,X had more severe presentation compared to patients with 45,X/46,XX and structural abnormalities of X chromosome.

    Patients with Turner syndrome are generally characterized by having short stature with no secondary sexual characteristics. Some abnormalities, such as webbed neck, renal malformations (>50%) and cardiac defects (10%) are less common. The intelligence of these patients is considered normal. Non-mosaic monosomy X is observed in approximately 45% of postnatal patients with Turner syndrome and the rest of the patients have structural abnormalities or mosaicism involving 46,X,i(Xq), 45,X/46,XX, 45,X and other variants. The phenotype of 45,X/46,X,+mar individuals varies by the genetic continent and degree of the mosaicism. The gene content of the marker chromosome is the most important when correlating the phenotype with the genotype. Here we present an 11-year-old female who was referred for evaluation of her short stature and learning disabilities. Conventional cytogenetic investigation showed a mosaic 45,X/46,X,+mar karyotype. Fluorescence in situ hybridization showed that the marker chromosome originated from the X chromosome within the androgen receptor (AR) and X-inactive specific transcript (XIST) genes. Therefore, it is possible that aberrant activation of the marker chromosome, compromising the AR and XIST genes, may modify the Turner syndrome phenotype. PMID:26744914

    DNA methylation is an important regulatory component which influences phenotypes by modulating gene expression. Changes in DNA methylation may lead to altered phenotypes and ability of an organism to respond to stress leading to subsequent manifestation of life style diseases, cancer, etc. The human X chromosome represents a classical model for epigenetic processes governing differential regulation of homologous chromosomes. X monosomy (45, XO) leads to Turner's syndrome in human with mild to severe phenotypes. Using a novel cDNA based high throughput approach of assessing genome wide methylation; we have examined the methylation landscape in human fibroblasts in 45, XO and 46, XX individuals. We report here that as expected methylation of X linked genes is different in these two situations. It was observed that methylation of several autosomal genes is also affected in this X monosomy state. Genes involved in bone remodeling, glucose sensitivity and ovarian function appear to be altered in addition to genes involved in epigenetic regulatory processes. This opens up interesting possibility of misregulation of DNA methylation in the X monosomy state resulting in altered gene expression and altered phenotypes. This may be one of the reasons for the variance, differential severity and penetrance in case of Turner's syndrome. We propose that a systematic analysis of the molecular genetic mechanisms governing this epigenetic regulation will open up new therapeutic interventions which will certainly help in reducing severity of the disease and help in better management of X monosomy (Turner's syndrome).

    Turner syndrome is a complex disorder caused by an absent or abnormal sex chromosome. It affects 1/2000-1/3000 live-born females. Congenital lymphoedema of the hands, feet and neck region (present in over 60% of patients) is a common and key diagnostic indicator, although is poorly described in the literature. The aim of this study was to analyse the medical records of a cohort of 19 Turner syndrome patients attending three specialist primary lymphoedema clinics, to elucidate the key features of the lymphatic phenotype and provide vital insights into its diagnosis, natural history and management. The majority of patients presented at birth with four-limb lymphoedema, which often resolved in early childhood, but frequently recurred in later life. The swelling was confined to the legs and hands with no facial or genital swelling. There was only one case of suspected systemic involvement (intestinal lymphangiectasia). The lymphoscintigraphy results suggest that the lymphatic phenotype of Turner syndrome may be due to a failure of initial lymphatic (capillary) function. PMID:25804399

    The co-occurrence of two numerical chromosomal abnormalities in same individual (double aneuploidy) is relatively rare and its clinical presentations are variable depending on the predominating aneuploidy or a combination effect of both. Furthermore, double aneuploidy involving both autosomal and sex chromosomes is seldom described. In this study, we present three patients with double aneuploidy involving chromosome 21 and sex chromosomes. They all had the classical non disjunction trisomy 21; that was associated with monosomy X in two of them and double X in the other. Clinically, they had most of the phenotypic features of Down syndrome as well as variable features characteristic of Turner or Klinefelter syndrome. Cytogenetic studies and fluorescence in situ hybridization (FISH) analysis were carried out for all patients and their parents. The first patient was a male, mosaic with 2 cell lines (45,X/47,XY,+21) by regular banding techniques and had an affected sib with Down syndrome (47,XY,+21). The second was a female, mosaic (46,X,+21/47,XX,+21) where monosomy X was detected only by FISH in 15 percentages of cells, nevertheless, stigmata of Turner syndrome was more obvious in this patient. The third patient had non mosaic double trisomy; Down-Klinefelter (48,XXY,+21) presented with Down syndrome phenotype. Parental karyotypes and FISH studies for these patients were normal with no evidence of mosaicism. In this report, we review the variable clinical presentations among the few reported cases with the same aneuploidy in relation to ours. Also, the proposed mechanisms of double aneuploidy and the occurrence of non-disjunction in more than one family member are discussed. This study emphasizes the importance of molecular cytogenetics studies for more than one tissue in cases with atypical features of characteristic chromosomal aberration syndromes. To our knowledge, this is the first report of double aneuploidy, Down-Turner and Down-Klinefelter syndromes in

    The risk of solid and hematological malignancy in patients with Turner syndrome, characterized by X chromosome monosomy in women, and Klinefelter syndrome, characterized with two and more X chromosomes in men, is not well established, but such evidence may have etiological implications on cancer development. We identified a total of 1,409 women with Turner syndrome and 1,085 men with Klinefelter syndrome from the Swedish Hospital Discharge and Outpatient Register. These individuals were further linked to the Swedish Cancer Register to examine the standardized incidence ratios (SIRs) of cancer using the general population without Turner and Klinefelter syndromes as reference. The overall risk of cancer was 1.34 for women with Turner syndrome; it was increased only for solid tumors. For a specific type of tumor, the risk of melanoma and central nervous system tumor was significantly increased. For persons with Klinefelter syndrome, the risk of solid tumors was decreased (SIR = 0.66), whereas the risk of hematological malignancy was increased (SIR = 2.72). Non-Hodgkin lymphoma and leukemia showed an increased SIR of 3.02 and 3.62, respectively. Our study supported the hypothesis that X chromosome plays an important role in the etiology of solid tumors. The underlying mechanisms for the increased incidence of non-Hodgkin lymphoma and leukemia in persons with Klinefelter syndrome need to be investigated further. PMID:27061708

    Turner's syndrome occurs in approximately 1 out of every 2,000 to 2,500 live-born girls. This genetically determined pathology is characterised by multiple congenital anomalies. A typical form of this syndrome is associated with a lack of one of the sex chromosomes (karyotype 45, X). From the point of view of plastic surgery, one of the most important elements of the therapy is correction of the webbed neck deformity. The aim of the study was to present the possibilities of surgical treatment of a webbed neck of patients with Turner's syndrome and the evaluation of treatment results. In the years 2000-2012, six children with Turner's syndrome were treated because of the webbed neck deformity. The age of patients ranged from 9 to 17 years. In the case of all patients, the aim was to distribute the neck skin folds by using Z-plasty in conjunction with a shift to the back of glabrous skin flaps mobilised from the anterolateral surface of the neck. In the case of four operated patients, the folds were completely removed and a correct symmetrical outline of the neck was obtained. One patient was found to have unilateral moderate webbed neck recurrence after about 2 years of treatment. In one case, the correction was insufficient. The performed surgical procedures enabled correction of low hairline only in the lateral parts of the neck. The lower line of the scalp in the central part of the neck has remained unchanged. The lateral approach with a shift of glabrous skin flap to the back, which we performed, allows for effective reduction of the webbed neck, excision of bands of the connective tissue and correction of the low hairline on the side of the neck. Z-plasty enables an adequate extension of scars and improves the contour of the neck. PMID:26146109

  13. Cornelia de Lange syndrome with NIPBL mutation and mosaic Turner syndrome in the same individual

    PubMed Central

    2012-01-01

    Background Cornelia de Lange syndrome (CdLS) is a dominantly inherited disorder characterized by facial dysmorphism, growth and cognitive impairment, limb malformations and multiple organ involvement. Mutations in NIPBL gene account for about 60% of patients with CdLS. This gene encodes a key regulator of the Cohesin complex, which controls sister chromatid segregation during both mitosis and meiosis. Turner syndrome (TS) results from the partial or complete absence of one of the X chromosomes, usually associated with congenital lymphedema, short stature, and gonadal dysgenesis. Case presentation Here we report a four-year-old female with CdLS due to a frameshift mutation in the NIPBL gene (c.1445_1448delGAGA), who also had a tissue-specific mosaic 45,X/46,XX karyotype. The patient showed a severe form of CdLS with craniofacial dysmorphism, pre- and post-natal growth delay, cardiovascular abnormalities, hirsutism and severe psychomotor retardation with behavioural problems. She also presented with minor clinical features consistent with TS, including peripheral lymphedema and webbed neck. The NIPBL mutation was present in the two tissues analysed from different embryonic origins (peripheral blood lymphocytes and oral mucosa epithelial cells). However, the percentage of cells with monosomy X was low and variable in tissues. These findings indicate that, ontogenically, the NIPBL mutation may have appeared before the mosaic monosomy X. Conclusions The coexistence in several patients of these two rare disorders raises the issue of whether there is indeed a cause-effect association. The detailed clinical descriptions indicate predominant CdLS phenotype, although additional TS manifestations may appear in adolescence. PMID:22676896

    2008-05-01

    The high abortion rate of 45,X embryos indicates that patients with Turner syndrome and 45,X karyotype could be mosaics, in at least one phase of embryo development or cellular lineage, due to the need for the other sex chromosome presence for conceptus to be compatible with life. In cases of structural chromosomal aberrations or hidden mosaicism, conventional cytogenetic techniques can be ineffective and molecular investigation is indicated. Two hundred and fifty patients with Turner syndrome stigmata were studied and 36 who had female genitalia and had been cytogenetically diagnosed as having "pure" 45,X karyotype were selected after 100 metaphases were analyzed in order to exclude mosaicism and the presence of genomic Y-specific sequences (SRY, TSPY, and DAZ) was excluded by PCR. Genomic DNA was extracted from peripheral blood and screened by the human androgen receptor (HUMARA) assay. The HUMARA gene has a polymorphic CAG repeat and, in the presence of a second chromosome with a different HUMARA allele, a second band will be amplified by PCR. Additionally, the CAG repeats contain two methylation-sensitive HpaII enzyme restriction sites, which can be used to verify skewed inactivation. Twenty-five percent (9/36) of the cases showed a cryptic mosaicism involving a second X and approximately 14% (5/36), or 55% (5/9) of the patients with cryptic mosaicism, also presented skewed inactivation. The laboratory identification of the second X chromosome and its inactivation pattern are important for the clinical management (hormone replacement therapy, and inclusion in an oocyte donation program) and prognostic counseling of patients with Turner syndrome.

    The purpose of this research was to describe the frequency and characteristics of the overlap syndrome among stable COPD patients (stage 2 to 4 according to GOLD). Material and method: We studied 46 patients with stable COPD recruited from the outpatient clinic of the CHU of Liege from May 2013 to April 2014. Definition of the overlap syndrome was based on the coexistence of post-bronchodilation FEV1/FVC < 70% and, either, an asthmatic history before the age of 40, or, at least, two functional and immune-inflammatory asthmatic traits : 1) significant FEV1 reversibility to inhaled bronchodilator (FEVI change >/= 200 ml and >/= 12% after bronchodilation), 2) eosinophilic inflammation : sputum eosinophils ≥ 3%,blood eosinophils ≥ 400/μl, or FENO ≥ 45 ppb, 3) clinical history of airway allergy, or total serum IgE ≥ 113 KU/l, or RAST ≥ 0,35 KU/l against major aeroallergens. 37% patients had the COPD-asthma overlap syndrome and this group had a higher CAT score reflecting more severe symptoms (24,6 ± 8,1 vs 19,4 ± 8, p < 0,05) despite similar level of airway obstruction. The transfer coefficient DLCO/VA was preserved in the overlap group (97 ± 24%), but altered in the pure COPD group (80 ± 20%), p < 0,05. Approximately one third of COPD patients present with the overlap syndrome and they are more symptomatic without any evidence of more severe airway obstruction. PMID:25902605

    Melatonin secretion was investigated in 13 girls with Turner's syndrome before and after long-term oestrogen administration. Oestrogen treatment resulted in an increase in the serum levels of the hormone and a decrease in blood progesterone concentration. No change, however, was observed in the melatonin secretion pattern (in terms of peak values, time of peak level and total melatonin secretion) after oestrogen therapy. A distinct circadian rhythm in serum melatonin was evident in all subjects with peak occurring around 0200 h and concentration similar to those of normal subjects. PMID:2516784

    Turner syndrome (TS) is a chromosomal abnormality, of which the presence and impact of coexisting psychiatric morbidity has received little attention. The present report describes an adolescent with mosaic karyotype TS who had major depressive disorder with the predisposing cause of psychosocial burden, and relieved with the treatment of sertraline and complete remission with combined use of estradiol valerate. The report suggests us to pay more attention on the mood disorders in children with TS, especially in adolescents. For treatment aspect, medications for improving the puberty development and short stature should be added to in addition to antidepressants if they had mood disorders. PMID:26698832

    Turner syndrome is one of the most common chromosomal disorders. It is caused by numerical or structural abnormalities of the X chromosome and results in short stature and gonadal dysgenesis. The short stature arises from haploinsufficiency of the SHOX gene, whereas overdosage contributes to tall stature. This report describes the first Korean case of Turner syndrome with tall stature caused by SHOX overdosage. The patient presented with primary amenorrhea and hypergonadotropic hypogonadism at the age of 17 years. Estrogen replacement therapy was initiated at that time. She displayed tall stature from childhood, with normal growth velocity, and reached a final height of 190 cm (standard deviation score, 4.3) at the age of 30 years. Her karyotype was 46,X, psu idic(X)(q21.2), representing partial monosomy of Xq and partial trisomy of Xp. Analysis by multiplex ligation-dependent probe amplification detected a duplication at Xp22.3-Xp22.2, encompassing the PPP2R3 gene near the 5'-end of the SHOX gene through the FANCD gene at Xp22.2.

    The Growject® database on human GH treatment in Turner syndrome was analyzed in the Turner Syndrome Research Collaboration, and the relationships of the frequencies of spontaneous breast development and spontaneous menarche with karyotype and GH treatment were investigated. One hundred and three cases started GH treatment with 0.5 IU/kg/ week (0.5 IU group), and their dose was increased to 0.35 mg/kg/wk midway through the treatment course. Another 109 cases started GH at a dose of 0.35 mg/kg/wk (0.35 mg group). Spontaneous breast development was observed in 77 (36.3%) of the 212 patients, and spontaneous menarche occurred in 31 patients (14.6%). The frequency of spontaneous breast development was significantly lower in patients with the 45,X karyotype and significantly higher in patients with a structural abnormality of the second X chromosome. The frequency of spontaneous menarche was significantly higher in patients with mosaicism characterized by X monosomy and a cellular line with no structural abnormality of the X chromosome. No significant differences in frequencies of spontaneous breast development and spontaneous menarche were observed between the two dose groups, indicating that GH treatment does not increase the frequency of spontaneous puberty.

    Background: Patients with Turner syndrome (TS) are prone to having metabolic abnormalities, such as obesity, dyslipidemia, hypertension, hyperinsulinemia and type 2 diabetes mellitus, resulting in increased risks of developing atherosclerotic diseases. Objective: To determine the effect of growth hormone (GH) therapy on serum cholesterol levels in prepubertal girls with TS enrolled in the Turner syndrome Research Collaboration (TRC) in Japan. Patients and methods: Eighty-one girls with TS were enrolled in the TRC, and their total cholesterol (TC) levels before GH therapy were compared with reported levels of healthy school-aged Japanese girls. TC levels after 1, 2 and 3 yr of GH treatment were available for 28 of the 81 patients with TS. GH was administered by daily subcutaneous injections, 6 or 7 times/wk, with a weekly dose of 0.35 mg/kg body weight. Results: Baseline TC levels revealed an age-related increase in TS that was in contrast to healthy girls showing unchanged levels. During GH therapy, TC decreased significantly after 1 yr of GH treatment and remained low thereafter. Conclusions: Girls with untreated TS showed an age-related increase in TC that was a striking contrast to healthy girls, who showed unchanged levels. GH therapy in girls with TS brought about a favorable change in TC that indicates the beneficial impact of GH on atherogenic risk. PMID:23926408

    Abstract. The Growject® database on human GH treatment in Turner syndrome was analyzed in the Turner Syndrome Research Collaboration, and the relationships of the frequencies of spontaneous breast development and spontaneous menarche with karyotype and GH treatment were investigated. One hundred and three cases started GH treatment with 0.5 IU/kg/ week (0.5 IU group), and their dose was increased to 0.35 mg/kg/wk midway through the treatment course. Another 109 cases started GH at a dose of 0.35 mg/kg/wk (0.35 mg group). Spontaneous breast development was observed in 77 (36.3%) of the 212 patients, and spontaneous menarche occurred in 31 patients (14.6%). The frequency of spontaneous breast development was significantly lower in patients with the 45,X karyotype and significantly higher in patients with a structural abnormality of the second X chromosome. The frequency of spontaneous menarche was significantly higher in patients with mosaicism characterized by X monosomy and a cellular line with no structural abnormality of the X chromosome. No significant differences in frequencies of spontaneous breast development and spontaneous menarche were observed between the two dose groups, indicating that GH treatment does not increase the frequency of spontaneous puberty.

    A 6-month-old girl was referred by an ophthalmologist because of postoperative bleeding. She was scheduled for operation because of persistent hyperplastic primary vitreous. Workups were done and prolonged partial thromboplastin time with normal platelet count, normal bleeding time, and prothrombin time were detected. There was negative family history of bleeding tendency in both maternal and paternal family, so at the first step, Factor XI assay was requested which was normal. Then, von Willebrand factor and factor VIII were assayed which was 127% and less than 1%, respectively. Severe factor VIII deficiency was not suspected in a girl unless in siblings of a hemophilic patient who gets married with her carrier cousin. Chromosomal study and genetic testing were requested and mosaic Turner syndrome (45 XO) with ring X (p22, 2q13) along with inversion 22 (hemizygote) was detected. Abdominal and pelvic sonography showed absence of both ovaries with presence of infantile uterus. Maternal genetic study was in favor of carrier of hemophilia (heterozygote inversion 22). To the best of our knowledge, this is the first case of association of Turner syndrome with severe hemophilia A and persistent hyperplastic primary vitreous. PMID:26484646

    Turner syndrome (TS) is a genetic disorder in females that arises from the loss of X chromosome material. Affected individuals demonstrate a characteristic neuropsychological profile of strengths in verbal processing and weaknesses in visuospatial processing, consistent with the Nonverbal Learning Disabilities syndrome. Previous research has described a wide range of visuospatial deficits in TS; however, their verbal abilities are less extensively studied. The present paper describes the processing difficulties of a 9-year-old girl with TS who demonstrated problems in integrating details of a complex visual display and using organizational terms to describe visual scenes or events. Her specific cognitive disabilities were thought to underlie some of the social and behavioral problems she was currently experiencing. Her pattern of results is consonant with the neuropsychological pattern that others have attributed to right hemisphere dysfunction and/or white matter abnormality. PMID:11992190

    The predisposition to malignancy that is dominantly inherited in Li-Fraumeni syndrome is associated with germline mutations of the tumour suppressor gene p53. Although second malignant neoplasms have been described in children with p53 mutations, the synchronous occurrence of two embryologically different tumours in these children has not been reported. A 20 month old girl with failure to thrive and congenital heart defects was found to have unilateral adrenal masses which, at surgical removal, proved to be an adrenocortical carcinoma and a ganglioneuroblastoma. Further investigation showed a germline p53 mutation and Turner syndrome. It remains to be determined what effect the 45,X chromosomal complement may have on the expression of neoplasms seen in patients with p53 germline mutations. Images PMID:9598730

    Children with chromosome 22q11.2 deletion syndrome (22q11.2DS), Fragile X syndrome (FXS), or Turner syndrome (TS) are considered to belong to distinct genetic groups, as each disorder is caused by separate genetic alterations. Even so, they have similar cognitive and behavioral dysfunctions, particularly in visuospatial and numerical abilities. To assess evidence for common underlying neural microstructural alterations, we set out to determine whether these groups have partially overlapping white matter abnormalities, relative to typically developing controls. We scanned 101 female children between 7 and 14years old: 25 with 22q11.2DS, 18 with FXS, 17 with TS, and 41 aged-matched controls using diffusion tensor imaging (DTI). Anisotropy and diffusivity measures were calculated and all brain scans were nonlinearly aligned to population and site-specific templates. We performed voxel-based statistical comparisons of the DTI-derived metrics between each disease group and the controls, while adjusting for age. Girls with 22q11.2DS showed lower fractional anisotropy (FA) than controls in the association fibers of the superior and inferior longitudinal fasciculi, the splenium of the corpus callosum, and the corticospinal tract. FA was abnormally lower in girls with FXS in the posterior limbs of the internal capsule, posterior thalami, and precentral gyrus. Girls with TS had lower FA in the inferior longitudinal fasciculus, right internal capsule and left cerebellar peduncle. Partially overlapping neurodevelopmental anomalies were detected in all three neurogenetic disorders. Altered white matter integrity in the superior and inferior longitudinal fasciculi and thalamic to frontal tracts may contribute to the behavioral characteristics of all of these disorders.

    Spontaneous procreation in Turner syndrome (TS) is a rare condition, and repeated gestation is even rarer. We report two spontaneous and successful pregnancies (at the age of 25 and 28 y) in a patient with TS (karyotype: 45,X/47,XXX, in 30 metaphases). Births were by caesarean section due to fetal-pelvic disproportion. Both children, a boy and a girl, were born at full term, with normal physical exam and karyotype. Despite the elevated pregnancy risks associated with TS co-morbidities, this report presents two successful spontaneous pregnancies with normal children in a patient with TS diagnosis after her deliveries. Gynecologists and obstetricians should be aware of this possibility when evaluating women with unusual short stature or dysmorphic features in order to implement a more cautious prenatal care in those being diagnosed with TS.

    Turner's syndrome (TS) is a chromosomal defect with partial or total absence of the X chromosome. Our objective is to report our experience in Greece with patients suffering from TS and trying to conceive; therefore, we present four patients with TS, who underwent In vitro fertilization (ICSI) with donor oocytes in order to get pregnant. Three out of four patients managed to conceive and bring pregnancy to completion. It was shown that patients diagnosed in childhood or adolescence with TS have the possibility to undergo hormone replacement therapy (HRT) and thus, secondary sexual characteristics as well as uterus of almost normal size can develop. Assisted reproduction techniques (ART), predominantly with donated oocytes, could give these patients the possibility to have children. PMID:26757887

She spent most of the time doing these activities which affected not only her academic performance, but also social relationships. A comprehensive treatment plan consists of both biological and psychological aspects, is the main point of this case. Low dose of risperidone (0.5 mg/day) was started to decrease the patient's stereotypic behaviors. Sertraline (12.5 mg/day) was prescribed for her phobia. She was also referred to an occupational therapist in order to improve her social skills. PMID:26015917

    Laparoendoscopic single-site surgery (LESS), a minimally invasive procedure, is gaining widespread acknowledgment in pediatric urology. We report the case of a 7-year-old girl with Turner's syndrome with 45,XO/46,XY mosaicism, for whom bilateral prophylactic gonadectomy using LESS was performed. Histopathological findings revealed bilateral streak gonads. The surgical and cosmetic outcome was excellent. Diagnostic and therapeutic laparoscopy is essential for accurate clinical management of patients with disorders of sex development. Although this is only a single case report, it supports the theory that LESS is an exceedingly practical and superior technique for such children, since it provides excellent magnification, as well as allowing normal psychological development owing to the concealed scar. Further studies and long-term follow-up are required to evaluate the benefits and limitations of applying LESS in pediatrics. PMID:22417680

    Complete or partial absence of the second sex chromosome, with or without a mosaic karyotype, is detected in approximately 1 per 2,500 live-born females. Such a cytogenetic finding coupled with clinical features, such as short stature and ovarian failure, supports the diagnosis of Turner's syndrome (TS). It is typically characterized by the combination of physical features and cytogenetics in females. The presenting clinical features can vary widely among affected individuals. Consequently, whereas short stature and gonadal dysgenesis are almost universal in TS, many other organ systems are affected to varying degrees and at different stages of life. The periodontal status of three females diagnosed with TS has been reported here. PMID:23162346

    Turner syndrome (TS) is a disorder caused by partial or complete X-chromosome monosomy. Studies in TS patients with different karyotypes have demonstrated the presence of Y-chromosome-derived sequences (4-61%). Early detection of Y-chromosome sequences in TS is of great importance because of the high risk of gonadal tumor development. We investigated the presence of Y-chromosome sequences in TS patients with a 45,X karyotype. One hundred seven unrelated 45,X Mexican TS patients recruited between 1992 and 2003 were included. Y-chromosome-derived sequences were found by polymerase chain reaction in 10 (9.3%) patients. Six subjects underwent gonadectomy and in one of them a gonadoblastoma was found; another developed a gonadoblastoma with dysgerminoma. Because of the high proportion (33%) of gonadal tumors in patients with Y-chromosome sequences found among our patients of mestizo origin, adequate counseling regarding a gonadectomy should be given.

We describe the case of a 60-yearold woman recently diagnosed with multiple myeloma who refers paresis, severe pruritus and itching lesions on the right arm with 6 months of evolution. Investigation led to a diagnosis of Brachioradial pruritus consequent to the presence of cervical disc herniation and Parsonage-Turner syndrome. The patient started gabapentin 900mg/day with good control of itching. Corticosteroids and antihistamines are often ineffective in the treatment of BP. Gabapentin has been used with encouraging results. All patients with Brachioradial pruritus should be evaluated for cervical spine injuries. PMID:26131874

    Within endocrinology, the long-term management of Turner syndrome (TS) in adults is fast becoming a specialist subject in its own right. The complications of TS can affect every system in the body, and the main reason why it falls to endocrinologists to coordinate health care is that many features are clearly within the endocrine remit: hypothyroidism, diabetes, hypertension, osteoporosis, hypogonadism. Endocrinologists as general physicians can often cover surveillance of problems in other areas such as congenital heart disease, inflammatory bowel disease and deafness, calling upon specialist input only if the need arises. In this way, a simple 'one stop shop' can offer a well-woman service for women with TS in a cost-effective manner. Such a service requires a multidisciplinary approach. PMID:20718775

    We report a unique case of Turner syndrome associated with acquired von Willebrand disease (AvWD), primary biliary cirrhosis (PBC), and inflammatory bowel disease (IBD). During 7 years of close follow-up, the patient presented with multiple major episodes of upper and lower gastrointestinal bleeding caused by different pathogenic mechanisms, such as IBD, AvWD, gastric varices, and thrombocytopenia. AvWD mimicking familial vWD type III on laboratory testing was most probably triggered by autoimmune mechanism associated with PBC. Therapy of PBC with ursodeoxycholic acid (UDCA) resulted in significant decrease of liver enzymes followed by normalization of vWF and FVIII levels. Portosystemic shunt placement with ligation of gastric varices improved hypersplenism and severe thrombocytopenia and led to clinical stability for more than 24 months. The clinicopathological features of these disorders and of the recurrent bleeding episodes are discussed in the text along with a review of the literature. PMID:12116986

    Parsonage-Turner Syndrome is a rare disease that affects the musculature of the scapular girdle, leading to muscle atrophy and large motor deficit. The etiology is uncertain, but it is believed that infectious and autoimmune factors are involved. The diagnosis is made by exclusion, and the main differential diagnoses are cervical disc hernias, rotator cuff injuries and rheumatic diseases. During diagnostic investigations, we perform laboratory tests, radiographs and MRI on the shoulders and cervical spine, with emphasis on electroneuromyography to help in making a definitive diagnosis. This case report is presented because it shows a disease that is rarely associated with HIV seropositivity and the importance of early diagnosis for better treatment of these patients. PMID:27022580

    Noonan syndrome (NS) and Turner syndrome (TS) are associated with cognitive problems and difficulties in affective information processing. While both phenotypes include short stature, facial dysmorphisms, and a webbed neck, genetic etiology and neuropsychological phenotype differ significantly. The present study examines putative differences in affective information processing and social assertiveness between adult women with NS and TS. Twenty-six women with NS, 40 women with TS, and 40 female controls were matched on age and intelligence, and subsequently compared on (1) alexithymia, measured by the Bermond-Vorst Alexithymia Questionnaire, (2) emotion perception, evaluated by the Emotion Recognition Task, and (3) social assertiveness and social discomfort, assessed by the Scale for Interpersonal Behavior. Women with TS showed higher levels of alexithymia than women with NS and controls (P-values < 0.001), whereas women with NS had more trouble recognizing angry facial expressions in comparison with controls (P = 0.01). No significant group differences were found for the frequency of social assertiveness and the level of social discomfort. Women with NS and TS demonstrated different patterns of impairment in affective information processing, in terms of alexithymia and emotion perception. The present findings suggest neuropsychological phenotyping to be helpful for the diagnosis of specific cognitive-affective deficits in genetic syndromes, for the enhancement of genetic counseling, and for the development of personalized treatment plans.

    Many patients with asthma or chronic obstructive pulmonary disease (COPD) have overlapping characteristics of both diseases. By spirometric definition, patients with both fixed airflow obstruction (AO) and bronchodilator reversibility or fixed AO and bronchial hyperresponsiveness can be considered to have asthma-COPD overlap syndrome (ACOS). However, patients regarded to have ACOS by spirometric criteria alone are heterogeneous and can be classified by phenotype. Eosinophilic inflammation, a history of allergic disease, and smoke exposure are important components in the classification of ACOS. Each phenotype has a different underlying pathophysiology, set of characteristics, and prognosis. Medical treatment for ACOS should be tailored according to phenotype. A narrower definition of ACOS that includes both spirometric and clinical criteria is needed. PMID:26161009

    We report a patient with oral-facial-digital syndrome type 1 (OFDS1) who exhibited features overlapping those of nevus comedonicus syndrome, an unusual presentation that may potentially represent a new variant of OFDS1. OFDS1 and nevus comedonicus syndrome represent two rare syndromes with numerous overlapping features that have yet to be described in relation to one another. The features present in our patient led us to propose the possibility of a new variant of OFDS1 in which nevus comedonicus represents a cutaneous manifestation of the syndrome. Knowledge of this potential relationship is important for identification and management of the syndromes' accompanying manifestations in affected patients and may offer further insight into crossroads of pathogenesis.

    Mosaic Turner syndrome is a common finding with 50% of the individuals with Turner syndrome having a second cell line. In rare cases, the additional chromosome is reported to be a Y or variant of the Y chromosome. We report a female with Turner Syndrome, who has a mosaic pattern, with the Y chromosome by GTL-banding appearing entirely normal, about the length of chromosome 22. Quinicrine-banding revealed no heterochromatic region. The father of the girl was unavailable for analysis. C-banding resulted in the determination of two centromeric regions, one active at the primary constriction and the second was inactive. The Y centromeric probe (Oncor) showed both the active and inactive centromeres to be of Y origin. Painting using whole chromosome Y paint (Imagenetics) revealed only Y material. In cases of males and females where 45,X/46,X,dic(Y) has been reported, a mosaic pattern has resulted from both centromeres being active in early embryogenesis. In this case the resulting chromosome looks to be a normal Y in both shape and size but with a mosaic pattern. Clearly, G-banding is not always adequate to determine a dic(Y). This suggests that any 45,X/46,SY mosaic pattern in either males or females should be evaluated for a possible dicentric Y chromosome.

    The aim of this study was to describe marital status, sexual history, and sexual functioning in a group of women with Turner syndrome, and to compare the results with general Swedish population data. The sample consists of 57 women over 18 years of age. Data were collected from an interview, and using two self-report questionnaires: the McCoy Sexual Rating Scale and the Relationship Rating Scale (RS). Compared to population data, the women with Turner syndrome were less likely to have a partner and had had their sexual debut later. Single women differed more from the general population than did women with a partner, regarding sexual desire and sexual activity. Several women with a partner reported sexual problems, but unanimously reported being satisfied with their sex life and partner relationship. The level of sexual desire in women with Turner syndrome is discussed in relation to Levine's model of human sexual desire, where psychological and social motivational factors are considered in addition to a biologically based sexual drive (Levine, 1992).

    Purpose: To present a patient with overlapping choriocapillaritis syndromes who first presented as a typical case of multiple evanescent white dot syndrome (MEWDS) and later with characteristic findings compatible with multifocal choroiditis (MFC). Case Report: A 40-year-old myopic woman presented with a paracentral scotoma OS. Fundus examination revealed pale discolored areas around the optic disc corresponding to faintly hyperfluorescent areas on fluorescein angiography (FA). On indocyanine green angiography (ICGA) there was extensive peripapillary hypofluorescence and confluent hypofluorescent dots superiorly. According to the clinical picture, a diagnosis of MEWDS was made. In 4 weeks, the visual field reverted to normal together with almost complete regression of hypofluorescence on ICGA. However, 4 months later fundus examination revealed some scars, a finding not typical for MEWDS. Besides, she developed another scotoma 12 months later accompanied by photopsia and the fundus illustrated more numerous scars than one year earlier. ICGA showed hypofluorescent areas corresponding to the scotoma delineated by visual field testing. The pattern of this recurrence clearly corresponded to MFC. Conclusion: This case illustrates an overlap between two entities, MEWDS and MFC in two sequential episodes. FA and fundus autofluorescence accounted for the lesions and optical coherence tomography showed damage to the photoreceptor outer segments, but only ICGA correlated well with functional evolution.

    Background. The presence of Y chromosome material in Turner's syndrome (TS) patients is a risk factor for the development of gonadoblastoma. Although conventional cytogenetic analysis is the definitive diagnosis of TS, low level Y chromosome mosaicism may be missed. Molecular analysis has demonstrated a higher proportion of mosaicism, but there is controversy regarding the prevalence of Y chromosome-derived material in those patients. Aim and Methods. This study was conducted to investigate the prevalence of hidden Y chromosome mosaicism in 48 TS Egyptian patients using polymerase chain reaction (PCR) for molecular DNA analysis of SRY gene and compare our results with those in the literature. Results. None of TS patients had a cytogenetically obvious Y chromosome; Y chromosome material was detected only at molecular analysis. SRY gene was found in 9 TS patients (18.75%) with the classical 45,X karyotype, whereas all other patients were SRY negative. Conclusion. Cytogenetically undetected Y chromosome mosaicism is common in TS patients; these data reinforce the need for adequate diagnosis of Y chromosome material in those patients. Molecular screening for Y chromosome-derived DNA should be routinely carried out in all TS patients. PMID:23984076

    Cytogenetic studies have shown that 40-60% of patients with Ullrich-Turner syndrome (UTS) are 45,X, whereas the rest have structural aberrations of the X chromosome or mosaicism with a second cell line containing a structurally normal or abnormal X or Y chromosome. However, molecular analysis has demonstrated a higher proportion of mosaicism, and studies in different populations have shown an extremely variable frequency of Y mosaicism of 0-61%. We used Southern blot analysis and polymerase chain reaction (PCR) to detect the presence of Ycen, ZFY, SRY, and Yqh in 50 Mexican patients with UTS and different karyotypes to determine the origin of marker chromosomes and the presence of Y sequences. Our results indicated the origin of the marker chromosome in 1 patient and detected the presence of Y sequences in 4 45,X patients. Taken together, we found a 12% incidence of Y sequences in individuals with UTS. The amount of Y-derived material was variable, making the correlation between phenotype and molecular data difficult. Only 1 patient had a gonadoblastoma. We discuss the presence of Y chromosomes or Y sequences in patients with UTS and compare our frequency with that previously reported. PMID:9511973

    Turner syndrome (TS) is at high risk for congenital heart diseases (CHD), aortic dilatation (AoDil) and dissection. New imaging techniques such as MRI have revealed the presence of vascular anomalies (VA) undetected at echo. MR angiography has shown a high prevalence of aortic and venous anomalies. The VA often coexist and interact to increase the risk of premature death in adulthood. AoDil and VA have been found also in asymptomatic individuals with no predisposing factors, but the prevalence is still unknown. We evaluated 100 TS subjects (15-35 yrs) with no aortic CHD at echocardiography with transthoracic MRA; 42 of them showed VA and 58 did not. Aortic diameters were indexed on BSA. At the sinuses of Valsalva a higher prevalence of AoDil was found in subjects with VA than without; 57% of them showed AoDil. The presence of VA (elongation of the transverse arch, bovine arch, left superior vena cava, PAPVD etc.) increased their relative risk of AoDil by more than 2 times. Excluding BSA influence, a severe phenotype influenced positively ascending AoDil. New imaging techniques enhance our ability to provide a prognosis for their adult age and in particular before they seek to become pregnant. PMID:22946280

    Objectives The purpose of this case report is to describe the chiropractic management of a patient presenting with right arm paralysis and a diagnosis of Parsonage-Turner syndrome. Clinical Features After receiving nerve entrapment release surgery, a 30-year-old man presented with a right arm contracture, atrophy, and weakness with general paralysis of the forearm and index finger of 6 weeks' duration. Intervention and Outcome The patient was provided chiropractic care that included high-velocity/low-amplitude spinal manipulation based upon applied kinesiology manual muscle testing, soft tissue trigger point therapy, exercises, and stretches. The patient demonstrated improvement in range of motion after the first treatment session. By the eighth treatment, he was able to fully straighten his arm. Three years later, the patient reported that he was able to do mountain climbing and that his arm was fully functional and pain-free. Conclusion For this patient, chiropractic care seemed to be successful in relieving his right arm paralysis and restoring normal arm movement. PMID:22654689

    Our aim was to examine possible somatic and social correlates to psychological well-being in adult women with Turner Syndrome (TS), including hormone replacement treatment Sixty-three women with a diagnosis of TS (mean age, 31.5 years) participated in a cross-sectional study, using interview data, ratings on the Psychological General Well-being (PGWB) Index, and data from medical examinations and medical records. Statistical analysis was performed by bivariate and multivariate analyses. Lack of sex hormones during adult life and the presence of hearing impairment were related to lower psychological well-being, as were higher age at diagnosis, higher age at menarche or induced bleeding, higher chronological age and retrospectively reported difficulties with school subjects. Age at diagnosis and difficulties with school subjects explained 25% of the variation in psychological well-being. This study has identified some correlates to psychological well-being in women with TS, which are important when considering the clinical management of adult women with TS. PMID:15715020

    Renal anomalies are present in up to 30% of patients with Turner syndrome (TS). Renal ultrasound (U/S) detects anatomical renal anomalies only while renal scintigraphy detects anomalies, detects early renal malfunction, and estimates glomerular filtration rate (GFR). Thus, we aimed to assess frequency of renal abnormalities detected by scintigraphy in comparison to renal U/S in TS patients. Ninety TS patients were subjected to auxological assessment, measurement of serum creatinine; and renal U/S and scintigraphy. Renal U/S detected renal anomalies in 22.22% of patients versus 17.78 % detected by scintigraphy (P = 0.035). Scintigraphy detected renal functional abnormalities in 44.44% of patients in the form of subnormal total GFR, abnormal renogram curve pattern, improper tracer handling and perfusion; and difference in split renal function >10% between both kidneys. Patients with a 45,X karyotype had more renal functional abnormalities (56%) than those with mosaic karyotype (33.33%), P = 0.04. In conclusion, renal scintigraphy is not superior to U/S in detection of renal anomalies but is a reliable method for early detection of renal malfunction in TS patients especially those with 45,X to ensure early management to offer a better quality of life.

    Social deficits are prevalent in Turner syndrome (TS); however, the extent to which these difficulties are secondary to characteristic cognitive impairments is not well known. Here, we sought to establish the relative contribution of executive functions, visuospatial abilities, and IQ to social difficulties in young girls with TS. Forty TS girls and 19 typically developing (TD) children were assessed with the Social Responsiveness Scale (SRS), the Motor-Free Visual Spatial Test (MVPT-3), the Behavior Rating Inventory of Executive Function (BRIEF), and an IQ test. Hierarchical multiple regression analyses were conducted with the SRS subscales as outcome variables. In a first step, the cognitive factors were entered (verbal IQ, BRIEF global score, MVPT-3, and age), followed by the group variable in a second step. In comparison to TD, TS participants were significantly impaired on all main measures. All six regression models with the SRS subscales were significant and revealed that global executive functions explained the largest portion of the variance on all subscales and the total score. Even after controlling for cognitive elements, the group factor still explained a significant portion of the variance of the Social Cognition, Social Awareness, and Autistic Mannerisms subscales. In contrast, the group factor was not a significant predictor of Social Motivation and Social Communication scores. These results suggest that executive dysfunctions play a role in social impairments encountered in TS, but also that some specific aspects of social behavior are altered beyond what can be attributed to cognitive difficulties in this population.

    The aim of this project was to study the impact on craniofacial morphology from Turner syndrome (TS) karyotype, number of intact X chromosomal p-arms, and age as well as to compare craniofacial morphology in TS with healthy females. Lateral radiographs from 108 females with TS, ranging from 5.4 to 61.6 years, were analysed. The TS females were divided into four karyotype groups: 1. monosomy (45,X), 2. mosaic (45,X/46,XX), 3. isochromosome, and 4. other, as well as according to the number of intact X chromosomal p-arms. The karyotype was found to have an impact on craniofacial growth, where the mosaic group, with presence of 46,XX cell lines, seems to exhibit less mandibular retrognathism as well as fewer statistically significant differences compared to the reference group than the 45,X karyotype. Isochromosomes had more significant differences versus the reference group than 45,X/46,XX but fewer than 45,X. To our knowledge, this is the first time the 45,X/46,XX and isochromosome karyotypes are divided into separate groups studying craniofacial morphology. Impact from p-arm was found on both maxillary and mandibular length. Compared to healthy females, TS expressed a shorter posterior and flattened cranial base, retrognathic, short and posteriorly rotated maxilla and mandible, increased height of ramus, and relatively shorter posterior facial height. The impact of age was found mainly on mandibular morphology since mandibular retrognathism and length were more discrepant in older TS females than younger. PMID:22531663

    Psychological well-being, self-rated health and social situation were investigated in a cross-sectional multidisciplinary study of 63 women with Turner syndrome (TS; mean age 31.5 years, range 18-59 years). The psychological examination included a semi-structured interview, and use of two standardized self-rating scales, the Psychological General Well-being Index (PGWB) and the Nottingham Health Profile (NHP). Psychological well-being and self-rated health were similar in the women with TS and Swedish female normative data, matched for age. However, the women with TS reported more social isolation than the normative group. Within the TS group, the oldest women reported more psychological distress and poorer health than the youngest. Those with impaired self-rated health reported more emotional distress. The women with TS were studying or in employment to the same degree as the general population, although fewer were cohabiting. In the interview, both negative and positive consequences of TS were reported. This study did not find any evidence for impaired psychological well-being, although it did indicate that women with TS experience more difficulties in the area of social and partner relationships.

    Turner syndrome (TS) is caused by a sex chromosome aberration. The aim was to study the prevalence and incidence of thyroid disease in adults with TS. Women with TS (n = 91; mean age, 37.7 +/- 11 yr) were compared with an age-matched female random population sample (n = 228). At baseline, 15 (16%) TS women were treated for hypothyroidism, and elevated serum TSH was found in another eight (9%). As a result, hypothyroidism was more common in women with TS (25%) than in controls (2%; P < 0.0001). Serum free T4 was lower (P = 0.02), and serum TSH was higher (P < 0.0001) in TS women than in age-matched controls. Of all TS women with hypothyroidism, 10 (43%) had an elevated thyroid peroxidase antibody titer vs. 15 (22%) of those without hypothyroidism (P < 0.05), evenly distributed between the karyotype 45,X and mosaicism. A high body mass index, but not a family history or blood lipids, was associated with hypothyroidism in TS. After the 5-yr follow-up, an additional 11 (16%) developed hypothyroidism, of whom four (36%) had elevated thyroid peroxidase. Altogether, 34 (37%) TS women had hypothyroidism after the 5-yr follow-up. Autoimmune hypothyroidism was common, with an annual incidence of 3.2% in TS. Thyroid function should be checked regularly in TS. PMID:15623818

    Folate metabolism dysfunction can lead to DNA hypomethylation and abnormal chromosomal segregation. Previous investigations of this association have produced controversial results. Here we performed a case-control study in patients with Turner syndrome (TS) to determine the effects of genetic polymorphisms of folate pathway genes as potential risk factors for somatic chromosomal nondisjunction. TS is a useful model for this investigation because patients with TS show a high frequency of chromosome mosaicism. Here we investigated the possible association of polymorphisms of the MTHFR gene with TS risk, which has been previously investigated with controversial results. We also examined the effects of MTR, RFC1, and TYMS gene polymorphisms in TS for the first time. The risk was evaluated according to allelic and genotype (independent and combined) frequencies among 70 patients with TS and 144 age-matched healthy control subjects. Polymorphism genotyping was performed by PCR, PCR-RFLP, and PCR-ASA. The polymorphisms MTHFR 677C>T and 1298A>C, MTR 2756A>G, RFC1 80G>A, and TYMS 2R/3R-alone or in combinations-were not associated with the risk of chromosomal aneuploidy in TS. In conclusion, our present findings did not support a link between impaired folate metabolism and abnormal chromosome segregation leading to somatic nondisjunction in TS patients. PMID:25858821

    Abstract Objective: To assess the prevalence of Y-chromosome sequences and gonadoblastoma in patients with Turner syndrome (TS) using molecular techniques. Data source: A literature search was performed in Pubmed, limiting the period of time to the years 2005–2014 and using the descriptors: TS and Y sequences (n=26), and TS and Y-chromosome material (n=27). The inclusion criteria were: articles directly related to the subject and published in English or Portuguese. Articles which did not meet these criteria and review articles were excluded. After applying these criteria, 14 papers were left. Data synthesis: The main results regarding the prevalence of Y-chromosome sequences in TS were: (1) about 60% of the studies were conducted by Brazilian researchers; (2) the prevalence varied from 4.6 to 60%; (3) the most frequently investigated genes were SRY, DYZ3 and TSPY; (4) seven studies used only polymerase chain reaction, while in the remaining seven it was associated with FISH. Nine of the 14 studies reported gonadectomy and gonadoblastoma. The highest prevalence of gonadoblastoma (33%) was found in two studies. In five out of the nine papers evaluated the prevalence of gonadoblastoma was 10–25%; in two of them it was zero. Conclusions: According to these data, molecular analysis to detect Y-chromosome sequences in TS patients is indicated, regardless of their karyotype. In patients who test positive for these sequences, gonadoblastoma needs to be investigated. PMID:26525685

    A 52-year-old woman with overlap syndrome and interstitial pneumonia underwent immunosuppressive therapy and she was suspected to suffer from pulmonary aspergillosis. Oral voriconazole was initiated, and a rapid elevation of alkaline phosphatase (ALP) occurred after 4 weeks. After 2 months, the patient presented diffuse pain in bilateral skeletal regions, and bone scintigraphy revealed bilateral multiple areas of increased radiotracer uptake. We suspected the skeletal involvement as voriconazole-induced periostitis. Actually, the plasma fluoride level was increased. Voriconazole was replaced with itraconazole, and after 3 weeks, the patient stopped complaining of bone pain concomitant with the decrease in ALP. Voriconazole-induced periostitis is a rare condition but had previously been reported in solid organ or patients with bone marrow transplant who received a long-term voriconazole therapy. Our present case is distinctive of previous ones, because it occurred in a patient with connective tissue disease which had its rapid progression. PMID:24599432

    Stevens-Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) are severe mucocutaneous disease with high mortality rate. It is characterised by severe necrosis and detachment of the epidermis. Drugs are the most common triggering agent for SJS/TEN. These are commonly reported with the use of aromatic antiepileptics, antiretrovirals, allopurinol, NSAID’S and sulfonamide antibiotics. Non antibiotic sulfonamides rarely cause SJS/TEN. Metolazone is a well known diuretic and is extensively used by clinicians. Although this drug is in market for last several decades, no case of SJS/TEN has been reported till date. We report a rare case of metolazone induced SJS/TEN overlap in a 55-year-old lady. PMID:27134890

    Studies of sex effects on neurodevelopment have traditionally focused on animal models investigating hormonal influences on brain anatomy. However, more recent evidence suggests that sex chromosomes may also have direct upstream effects that act independently of hormones. Sex chromosome aneuploidies provide ideal models to examine this framework in humans, including Turner syndrome (TS), where females are missing one X-chromosome (45X), and Klinefelter syndrome (KS), where males have an additional X-chromosome (47XXY). As these disorders essentially represent copy number variants of the sex chromosomes, investigation of brain structure across these disorders allows us to determine whether sex chromosome gene dosage effects exist. We used voxel-based morphometry to investigate this hypothesis in a large sample of children in early puberty, to compare regional gray matter volumes among individuals with one (45X), two (typically developing 46XX females and 46XY males), and three (47XXY) sex chromosomes. Between-group contrasts of TS and KS groups relative to respective sex-matched controls demonstrated highly convergent patterns of volumetric differences with the presence of an additional sex chromosome being associated with relatively decreased parieto-occipital gray matter volume and relatively increased temporo-insular gray matter volumes. Furthermore, z-score map comparisons between TS and KS cohorts also suggested that this effect occurs in a linear dose-dependent fashion. We infer that sex chromosome gene expression directly influences brain structure in children during early stages of puberty, extending our understanding of genotype–phenotype mechanisms underlying sex differences in the brain.

    A 29-yr-old female western lowland gorilla (Gorilla gorilla gorilla) was evaluated for low fertility and a midterm abortion. Laboratory testing included karyotyping, which revealed an unusual mosaicism for Turner syndrome with Triple X (47,X/49,XXX). This appears to be the first report of Turner syndrome in a great ape. In humans, Turner syndrome occurs in approximately 1 in 3,000 females, with half of those monosomic for the X chromosome. A small proportion is mosaic for a triple X cell line (3-4%). In humans, Turner syndrome is associated with characteristic phenotype including short stature, obesity, a broad chest with widely spaced nipples, webbing of the neck, and anteverted ears. This individual gorilla is significantly shorter in stature than conspecifics and is obese despite normal caloric intake. Individuals with Turner syndrome should also be screened for common health issues, including congenital heart defects, obesity, kidney abnormalities, hypertension, hypothyroidism, and diabetes mellitus. Animals with decreased fertility, multiple miscarriages, fetal losses, unusual phenotypes, or a combination of these symptoms should be evaluated for genetic abnormalities. PMID:24450068

    Final height of 75 adults with Turner's syndrome (45 Israeli, 30 Italian), never treated with GH, was examined to see if a relationship with karyotype patterns and parental height existed. Patients were divided into five groups according to their chromosome pattern, as follows: group A = 45, X karyotype (34 patients); group B = mosaicism (11 with karyotype 45,X/46,XX and 7 with karyotype 45,X/46,XY); group C = deletion of all or part of Xp (19 patients); subgroup C1 = 6 with complete deletion of Xp; subgroup C2 = 9 with mosaicism 45,X/46,X,i(Xq); subgroup C3 = 4 with 45,X/46,X,ring(X); group D = deletion of Xq (4 patients); pure gonadal dysgenesis (PGD) group = 9 patients with pure 46,XX gonadal dysgenesis. No statistical difference was noted between the mean height of the two national populations studied (Italian 142.2 +/- 5.7 and Israeli 143.0 +/- 7.2 cm). The mean heights of group D (148.9 cm; range 147-166.2) and the PGD group (156.0 cm; 141-171.5) were found to be significantly higher than those observed in groups A, B and C (p < 0.03, p < 0.02 and p < 0.02, respectively), even though gonadal distinction existed in all five groups. Subgroup C1, where a deletion of the entire Xp segment [46,X,i(Xq)] was present, was found to be the shortest group (median height 134.5; range 131.9-138 cm).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7633152

    A combination of Turner syndrome (TS) and classical congenital adrenal hyperplasia (CAH) is rare. A one-day-old newborn was referred to our hospital with ambiguous genitalia. The parents were third-degree relatives. The infant's weight was 3350g (50-75p), and the head circumference was 34.5cm (50p). The gonads were nonpalpable. Presence of a 3 cm phallus, one urogenital opening into the perineum, and incomplete labial fusion were identified. Laboratory tests revealed a classical type of CAH due to 21-hydroxylase deficiency. Karyotyping revealed a 45X0(35)/46XX(22) pattern with negative sex-determining region Y (SRY) on gene analysis. At the most recent follow-up visit, the patient appeared to be in good health - her height was 70.4 cm [-1.5 standard deviation (SD)] and her weight was 9.8 kg (0.3 SD). She was receiving hydrocortisone in a dose of 10 mg/m²/day, fludrocortisone acetate in a dose of 0.075 mg/day, and oral salt of 1 g/day. System examinations were normal. The patient's electrolyte levels were found to be normal and she was in good metabolic control. The findings of this patient demonstrate that routine karyotyping during investigation of patients with sexual differentiation disorders can reveal TS. Additionally, signs of virilism should always be investigated at diagnosis or during physical examinations for follow-up of TS cases. SRY analysis should be performed primarily when signs of virilism are observed. CAH should also be considered in patients with negative SRY. PMID:23261864

    Children with Turner syndrome (TS) have a broad range of later health problems, including an increased risk of cardiovascular morbidity and mortality. The aim of this study was to evaluate the relationship between periaortic fat thickness (PAFT) and metabolic and cardiovascular profiles in children with TS. Twenty-nine TS and 29 healthy children and adolescents were enrolled in the study. Anthropometric measurements, pubertal staging, and blood pressure measurements were performed. Fasting serum glucose, insulin, and lipid profile were measured. Periaortic fat thickness was measured using an echocardiography method, which has not previously been applied in children with TS. No difference was found between TS and control subject (CS) in age, weight, waist/hip ratio, HDL cholesterol and LDL cholesterol levels. However, in TS subjects, total cholesterol (p = 0.045) was greater than that in controls. It was determined that 13.7 % (N: 4) of TS subjects had dyslipidemia. Mean fasting glucose, fasting insulin, QUICK-I, HOMA, and FGIR index were similar in TS and in CS, whereas 17.2 % (N: 5) of TS subjects had insulin resistance (IR) and 13.7 % (N: 4) had impaired glucose tolerance. Six subjects (20.6 %) were diagnosed as hypertensive. Periaortic fat thickness was significantly higher in the TS group (p < 0.001) (0.1694 ± 0.025 mm in the TS group and 0.1416 ± 0.014 mm in the CS group) In children with TS, PAFT was positively correlated with fasting insulin, body mass index, and diastolic blood pressure. Our results provide additional evidence for the presence of subclinical cardiovascular disease in TS. In addition to existing methods, we recommend the measurement of periaortic fat thickness in children with TS to reveal the presence of early atherosclerosis. PMID:25601134

    Turner syndrome is a genetic disorder caused by the complete or partial absence of an X chromosome in affected women. Individuals with TS show characteristic difficulties with executive functions, visual-spatial and mathematical cognition, with relatively intact verbal skills, and congruent abnormalities in structural development of the posterior parietal cortex (PPC). The functionally heterogeneous PPC has recently been investigated using connectivity-based clustering methods, which sub-divide a given region into clusters of voxels showing similar structural or functional connectivity to other brain regions. In the present study, we extended this method to compare connectivity-based clustering between groups and investigate whether functional networks differentially recruit the PPC in TS. To this end, we parcellated the PPC into sub-regions based on temporal correlations with other regions of the brain. fMRI data were collected from 15 girls with TS and 14 typically developing (TD) girls, aged 7-14, while they performed a visual-spatial task. Temporal correlations between voxels in the PPC and a set of seed regions were calculated, and the PPC divided into clusters of voxels showing similar connectivity. It was found that in general the PPC parcellates similarly in TS and TD girls, but that regions in bilateral inferior parietal lobules, and posterior right superior parietal lobule, were reliably recruited by different networks in TS relative to TD participants. These regions showed weaker correlation in TS with a set of regions involved in visual processing. These results suggest that abnormal development of visuospatial functional networks in TS may relate to the well documented cognitive difficulties in this disorder. PMID:22711287

Cytogenetic analysis of the peripheral blood lymphocytes revealed normal autosomes with 46X inv (Y) confirming the diagnosis of Turner's syndrome with Y cell line. Treatment was initiated with conjugated estrogen while recommending bilateral prophylactic oophorectomy to the patient. One year later the patient presented with abdominal mass, biopsy of the specimen following resection confirmed dysgerminoma originating from right ovary with no invasion or metastasis. The literature is reviewed with regard to the various pathogenetic mechanisms proposed for the development of germ cell tumors in ovary, the cytogenetic findings and recommendations to handle such scenario.

    Turner syndrome (TS) is a genetic disease with an incidence rate of between 1:2000 and 1:5000 live female births. The treatment of TS differs according to age and Recombinant Human Growth Hormone (RHGH) therapy is usually given for the treatment of short stature in girls with TS in childhood. We describe the first case of a TS patient who presented with a clinical picture compatible with oral and palmoplantar lichen planus-like reaction during RHGH therapy; spontaneous remission occurred after therapy suspension.

    Asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) is characterized by persistent airflow limitation with several features usually associated with asthma and several features usually associated with COPD. ACOS may be a special phenotype of a spectrum of chronic obstructive airway diseases, in which asthma and COPD are at the two opposite ends. The prevalence of ACOS varies considerably due to differing criteria being applied for diagnosis. Patients with ACOS utilize a large proportion of medical resources. They are associated with more frequent adverse outcomes than those with asthma or COPD alone. ACOS is currently a diagnostic challenge for physicians because there are no specific biomarkers to differentiate ACOS from asthma or COPD. The approach to diagnosing ACOS depends on the population from which the patient originated. The management of ACOS should be individualized to ensure the most effective treatment with minimal side effects. In this paper, we review the diagnostic criteria of ACOS used in previous studies, propose practical approaches to diagnosing and managing ACOS and raise some research questions related to ACOS.

    Gonadal dysgenesis and Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) are the most common causes of primary amenorrhoea. Patients with gonadal dysgenesis present with primary amenorrhoea and lack of secondary sexual characteristics, which, in contrast, are present in patients with MRKHS. The coexistence of the 2 syndromes has been reported in only a few studies so far. We describe a case of a 15-year-old girl who presented with short stature and primary amenorrhoea. Investigations revealed hypergonadotropic hypogonadism, and absence of the uterus, and upper two-thirds of the vagina, with presence of the rudimentary lower third of the vagina and non-visualised bilateral ovaries on imaging. Karyotyping obtained by lymphocyte culture GTG banding revealed 45X/46XX. The patient was diagnosed as having a rare case of gonadal dysgenesis with MRKH. She was started on growth hormone therapy. The association of these syndromes is uncommon, and has further implications on fertility and pregnancy, affecting the quality of life. PMID:27207981

    We present a unique case of juvenile polyposis and hereditary hemorrhagic telangiectasia overlap syndrome. The patient was found to have polyps on colonoscopy leading to genetic testing revealing an SMAD4 mutation. In children with SMAD4 mutation and juvenile polyposis, this overlap syndrome needs to be considered in the differential diagnosis and prompt the clinician to look for telangiectasias on examination and consider surveillance imaging to look for arteriovenous malformations. Our case highlights this clinical relationship and shows how nontraditional imaging using computed tomography colonography (CTC) can provide complimentary information along with colonoscopy. Despite low-dose techniques, CTC does add a radiation burden in the evaluation of these children who are at high risk for malignancy and should be used cautiously. PMID:25432397

    Background Some patients with COPD may share characteristics of asthma; this is the so-called asthma–COPD overlap syndrome (ACOS). There are no universally accepted criteria for ACOS, and most treatments for asthma and COPD have not been adequately tested in this population. Materials and methods We performed a survey among pulmonology specialists in asthma and COPD aimed at collecting their opinions about ACOS and their attitudes in regard to some case scenarios of ACOS patients. The participants answered a structured questionnaire and attended a face-to-face meeting with the Metaplan methodology to discuss different aspects of ACOS. Results A total of 26 pulmonologists with a mean age of 49.7 years participated in the survey (13 specialists in asthma and 13 in COPD). Among these, 84.6% recognized the existence of ACOS and stated that a mean of 12.6% of their patients might have this syndrome. In addition, 80.8% agreed that the diagnostic criteria for ACOS are not yet well defined. The most frequently mentioned characteristics of ACOS were a history of asthma (88.5%), significant smoking exposure (73.1%), and postbronchodilator forced expiratory volume in 1 second/forced vital capacity <0.7 (69.2%). The most accepted diagnostic criteria were eosinophilia in sputum (80.8%), a very positive bronchodilator test (69.2%), and a history of asthma before 40 years of age (65.4%). Up to 96.2% agreed that first-line treatment for ACOS was the combination of a long-acting β2-agonist and inhaled steroid, with a long-acting antimuscarinic agent (triple therapy) for severe ACOS. Conclusion Most Spanish specialists in asthma and COPD agree that ACOS exists, but the diagnostic criteria are not yet well defined. A previous history of asthma, smoking, and not fully reversible airflow limitation are considered the main characteristics of ACOS, with the most accepted first-line treatment being long-acting β2-agonist/inhaled corticosteroids.

    Turner's syndrome (TS) is a common disorder (1/2500 to 1/5000 female births) which is diagnosed at birth in approximately 20% of patients and during childhood or at puberty for the rest. Growth retardation is the most frequent clinical feature of TS, so we systematically searched for TS in female patients referred to our center because of short stature. Three hundred seventy-five female patients, 1 month to 18 yr old (mean +/- SD = 9(7/12) +/- 3(9/12), with growth retardation (less than -2 SD) and/or decreased height velocity were included in the study. Mean growth retardation was -2.57 SD +/- 0.79 (range: -1 to -7). Thirty-two percent of the patients had reached puberty. GH provocative tests were performed in 329 patients (87.7%), and 36 of these patients (11%) had impaired GH secretion (5 complete and 31 partial GH deficiency). TS was evaluated by Southern blot analysis of leukocyte DNA using a multiallelic polymorphic X chromosome marker (88% heterozygosity rate). Y chromosome PCR analysis was carried out if a pattern indicative of TS was obtained. Leukocyte DNA analysis produced an abnormal restriction pattern for 20 of the 375 cases (5.3%). There was a single hybridizing band in 13 cases, an allelic disproportion indicative of mosaicism in 6 cases, and 3 hybridizing bands in 1 case. One patient tested positive in the Y chromosome PCR analysis. Cytogenetic analysis showed 47 XXX trisomy in the patient with a 3-hybridizing-band pattern and confirmed the diagnosis of TS for 17 of the 19 suspected cases: 45 X: n = 7; 45 X/46 Xi(Xq): n = 4; 45 X/46 XX: n = 2; 46 Xi(Xq): n = 1; 45 X/46 Xr(X): n = 1; 45 X/46 XX/47 XXX: n = 1; 45 X/46 XY: n = 1. Cytogenetic analysis was normal (46 XX) for the 2 other patients. The TS phenotype is variable: dysmorphism is often missing or mild (particularly in cases of mosaicism), but growth is reduced in virtually all patients. Screening of 375 growth-retarded girls identified 18 cases of TS, of which 17 were diagnosed by molecular

    A total of 29 women with Turner's syndrome (19 monosomy and 10 mosaic) had 68 cycles of oocyte donation that included 29 cycles of initial attempt and 39 cycles of subsequent attempts. Oral oestradiol valerate was used either in a variable dose (42 cycles) or in a constant dose (26 cycles) regimen for the endometrial preparation which was monitored by pelvic ultrasonography. The embryos/zygotes were transferred either fresh (50 cycles) or after cryopreservation (18 cycles) into the Fallopian tube (41 cycles) and uterine cavity (27 cycles) as appropriate. There were 28 clinical pregnancies including two sets of triplets resulting in a pregnancy rate of 41.2% per treatment cycle and an implantation rate of 17.1% per embryo transferred. The recipient's age, chromosomal constitution or associated uterine or tubal anomaly had no influence on the treatment outcome. The implantation and pregnancy rates were higher in the subsequent than initial cycles (22.6 versus 9.99%, P < 0.05; 51.3 versus 27.6%, P < 0.05). An endometrial thickness of > or = 6.5 mm was an important predictor of pregnancy but the endometrial echo pattern failed to predict the outcome. Although the total dose of oestradiol before embryo transfer was higher in the pregnant cycles than the non-pregnant ones and its gradation (< 50 mg, 50-100 mg, < 100 mg) influenced the implantation (3.4, 17.5, 26.3% respectively, P < 0.05) and pregnancy rates (10, 42.2, 61.5% respectively, P < 0.05), the effect was indirect by altering the endometrial thickness. The number of oocytes fertilized affected the pregnancy rate irrespective of the number of embryos transferred. The implantation and pregnancy rates were higher when fresh rather than frozen-thawed embryos were transferred (20.3 versus 8.2%, P < 0.05; 48 versus 22.2%, P < 0.05) but the route of transfer was of no statistical importance. The overall miscarriage rate was higher (50%), and was related to the presence of hypoplastic or bicornuate uterus and to a low

    Objective: Turner syndrome (TS) is a chromosomal disorder caused by complete or partial X chromosome monosomy that manifests various clinical features depending on the karyotype and on the genetic background of affected girls. This study aimed to systematically investigate the key clinical features of TS in relationship to karyotype in a large pediatric Turkish patient population. Methods: Our retrospective study included 842 karyotype-proven TS patients aged 0-18 years who were evaluated in 35 different centers in Turkey in the years 2013-2014. Results: The most common karyotype was 45,X (50.7%), followed by 45,X/46,XX (10.8%), 46,X,i(Xq) (10.1%) and 45,X/46,X,i(Xq) (9.5%). Mean age at diagnosis was 10.2±4.4 years. The most common presenting complaints were short stature and delayed puberty. Among patients diagnosed before age one year, the ratio of karyotype 45,X was significantly higher than that of other karyotype groups. Cardiac defects (bicuspid aortic valve, coarctation of the aorta and aortic stenosis) were the most common congenital anomalies, occurring in 25% of the TS cases. This was followed by urinary system anomalies (horseshoe kidney, double collector duct system and renal rotation) detected in 16.3%. Hashimoto’s thyroiditis was found in 11.1% of patients, gastrointestinal abnormalities in 8.9%, ear nose and throat problems in 22.6%, dermatologic problems in 21.8% and osteoporosis in 15.3%. Learning difficulties and/or psychosocial problems were encountered in 39.1%. Insulin resistance and impaired fasting glucose were detected in 3.4% and 2.2%, respectively. Dyslipidemia prevalence was 11.4%. Conclusion: This comprehensive study systematically evaluated the largest group of karyotype-proven TS girls to date. The karyotype distribution, congenital anomaly and comorbidity profile closely parallel that from other countries and support the need for close medical surveillance of these complex patients throughout their lifespan.

    Sympathetic nervous system hyperactivity plays a role in development and progression of hypertension. While renal denervation employing radiofrequency devices has been used therapeutically in treating severe hypertension with alternate results in adults, few data are available regarding children. We treated a 6-year-old girl affected by Turner syndrome presenting severe hypertension and an episode of stroke, in spite of treatment with four antihypertensive drugs, with sympathetic ablation. The Simplicity device (Medtronic, Minneapolis, USA) was adapted to the smaller vessels, allowing a tailored approach. After 3 and 6 months of treatment, and β-blocker discontinuation, blood pressure values were set between the 90th and 95th centiles for sex and age, and normalised at 12 months. We confirm that renal denervation can be used to treat severe hypertension in children; miniaturisation of catheter and tailoring the procedure for small vessels allowed a safe approach. Progressive improvement of blood pressure had a satisfactory clinical impact. PMID:25759273

    The presence of the Y chromosome in the karyotype of patients with disorders of sex differentiation is significantly associated with an increased risk to develop specific types of malignancies, predominantly type II germ cell tumors (GCTs). Gonadoblastoma in the gonads without an obvious testicular differentiation and intratubular germ cell neoplasia of unclassified type in testicular tissue are the precursor lesions of most GCTs. Gonadal dysgenesis, the characteristic feature of Ullrich-Turner syndrome (UTS), further contributes to increase this tumor risk. The reported incidence of Y chromosome material in UTS is 6 to 8% and in these cases an early gonadectomy is strongly recommended to prevent the risk of a malignancy. The aim of this work was to retrospectively analyze the clinical outcome and the histopathological and cytogenetic findings of our UTS patients who underwent gonadectomy to establish strict selection criteria aimed at promoting an organ-sparing surgery.

    The case is about a young female who delivered twins by caesarean section (CS). On the 4th postoperative day, she presented with ascites which was resistant to empirical antibiotic and diuretic treatment. The woman was affected by Turner syndrome (TS); she had a medical background of chronic use of hormonal medication since puberty and conceived through ART- (assisted reproduction techniques-) IVF-oocyte donation. It is important to exhibit high suspicion for clot formation in the hepatic vasculature during the puerperium, especially in the case of history of chronic hormone treatment. Ascites albumin gradient and Doppler values lead to the diagnosis of thrombosis and the administration of high doses of anticoagulants is considered to be fundamental. PMID:26579320

    Background. Autoimmune encephalitis is a disorder characterised by the subacute onset of seizures, short-term memory loss, and psychiatric and behavioural symptoms. Initially, it was recognised as a paraneoplastic disorder, but recently a subgroup of patients without systemic cancer was identified. Case Description. We describe a 20-year-old woman with Turner syndrome presenting with a treatment-resistant rapid cycling bipolar disorder with cognitive impairment. She was diagnosed with anti-AMPA-receptor encephalitis. She showed marked improvement after starting memantine and valproic acid. Conclusion. This case description emphasises the importance of timely recognition of autoimmune limbic encephalitis in patients with psychiatric manifestations and a possible predisposition to autoimmune conditions, in order to rule out malignancy and to quickly initiate treatment.

    Background: Langerhans cell histiocytosis (LCH) is a rare disease involving clonal proliferation of cells with characteristics similar to bone marrow-derived Langerhans cells. The case of a young woman, affected by Turner syndrome and a solitary intraparenchymal LCH associated with an osteolytic lesion of the overlying skull, is presented. Case Description: The patient, with an insidious history of headache and a growing soft mass in the left frontal region, presented with a sudden generalized tonic-clonic epileptic seizure. Neuroradiological investigations showed an osteolytic lesion of the left frontal bone and an underlying brain lesion associated with recent signs of bleeding. The patient was operated on with a complete removal of the lesion. The postoperative course was uneventful. Conclusions: The clinical, neuroradiological, and intraoperative findings are presented, along with a review of the literature. Although rare, LCH should be considered in the differential diagnosis when a scalp lesion occurs with a progressive growing. PMID:27127696

    Fanconi anemia (FA) is a recessively inherited disease characterized by multiple symptoms including growth retardation, skeletal abnormalities, and bone marrow failure. The FA diagnosis is complicated due to the fact that the clinical manifestations are both diverse and variable. A chromosomal breakage test using a DNA cross-linking agent, in which cells from an FA patient typically exhibit an extraordinarily sensitive response, has been considered the gold standard for the ultimate diagnosis of FA. In the majority of FA patients the test results are unambiguous, although in some cases the presence of hematopoietic mosaicism may complicate interpretation of the data. However, some diagnostic overlap with other syndromes has previously been noted in cases with Nijmegen breakage syndrome. Here we present results showing that misdiagnosis may also occur with patients suffering from two of the three currently known cohesinopathies, that is, Roberts syndrome (RBS) and Warsaw breakage syndrome (WABS). This complication may be avoided by scoring metaphase chromosomes—in addition to chromosomal breakage—for spontaneously occurring premature centromere division, which is characteristic for RBS and WABS, but not for FA.

    We report a 72-year-old woman with overlapping Miller Fisher syndrome (MFS), Guillain-Barré syndrome (GBS) and Bickerstaff's brainstem encephalitis (BBE). She developed diplopia and unsteady gait a week after an upper respiratory infection on day 1. She had weakness of both upper limbs on day 3 and became drowsy, and her respiratory status worsened on day 5. Neurologic examination revealed ophthalmoplegia, ataxia, symmetrical weakness, areflexia, and consciousness disturbance. We diagnosed her with MFS on day 1, GBS on day 3 and overlapping BBE on day 5. She underwent immunoadsorption therapy and two courses of intravenous immunoglobulin therapy. Ten months after onset, her symptoms had fully recovered. Anti-GM1 IgG, GD1a IgG, GQ1b IgG, and GT1a IgG antibodies were positive. Our case supports the notion that MFS, GBS, and BBE are all part of a continuous clinical spectrum, which is an antibody-mediated process. PMID:23275783

    We describe a spontaneous uterine rupture at 14 weeks gestation in a Turner patient. A 39 year-old patient was admitted for abdominal pain and hypotension at 14 weeks of pregnancy. The pregnancy had been obtained by oocyte donation and in vitro fertilization (IVF) because of Turner's syndrome. The abdominal ultrasound scan showed a normal pregnancy and a conserved foetal cardiac activity. It also showed a large amount of free fluid in the perihepatic space. Haemoglobin was 11.2 g/dL. After hemodynamic degradation, urgent laparoscopy showed an unrepairable uterine rupture with partial exteriorisation of the pregnancy, and placenta percreta. Urgent conversion to laparotomy allowed haemostatic hysterectomy. Uterine rupture during pregnancy obtained by oocyte donation in Turner's syndrome may be life threatening. The possibility of such a complication should be considered before oocyte donation for IVF in Turner's patients. Early spontaneous uterine rupture (second trimester) is a challenging diagnostic that should be evoked in case of non-specific abdominal pain in the presence of risk factors. PMID:25858617

    Megacystis-microcolon-intestinal hypoperistalsis syndrome (MMIHS) is a rare, often fatal condition. Infants present with a functional obstruction of the gastrointestinal tract (GI), malrotation, microcolon, and a large nonobstructed bladder. Several features common to both MMIHS and Eagle-Barrett or prune belly syndrome (PBS) include hydronephrosis, bladder distension and laxity of the abdominal wall musculature. Additionally, MMIHS and PBS have been reported in the same family, suggesting the possibility of a common pathogenesis. MMIHS usually presents in female infants. We present a male infant diagnosed with both MMIHS and PBS. This is a unique case in which both MMIHS and true PBS are present in the same infant. PMID:15289943

    In this report, we describe bilateral gonadal tumors with characteristic histopathological findings in a patient with Turner's syndrome who had 45,X/46,X, +mar mosaicism. The left gonad contained a gonadoblastoma and a remnant of streak gonad. The right gonad was entirely replaced by a 15x11x7-cm solid and cystic tumor, which was revealed to be a combination of a mixed germ cell tumor and a cavernous hemangiomatous lesion. The latter occupied approximately half of the entire tumor volume, and there was an incomplete boundary between it and the mixed germ cell tumor lesion. To our knowledge, this is the first reported case of Turner's syndrome with a combination of a mixed germ cell tumor and a hemangiomatous lesion in the gonad. PMID:7979900

    Background Individuals with COPD and asthma are an important but poorly characterized group. The genetic determinants of COPD-asthma overlap have not been studied. Objective Identify clinical features and genetic risk factors for COPD-asthma overlap. Methods Subjects were current or former smoking non-Hispanic whites (NHW) or African-Americans (AA) with COPD. Overlap subjects reported a history of physician-diagnosed asthma before the age of 40. We compared clinical and radiographic features between COPD and overlap subjects. We performed genome-wide association studies (GWAS) in the NHW and AA populations, and combined these results in a meta-analysis. Results More women and African Americans reported a history of asthma. Overlap subjects had more severe and more frequent respiratory exacerbations, less emphysema, and greater airway wall thickness compared to subjects with COPD alone. The NHW GWAS identified SNPs in CSMD1 (rs11779254, P=1.57×10−6) and SOX5(rs59569785, P=1.61×10−6) and the meta-analysis identified SNPs in the gene GPR65 (rs6574978, P=1.18×10−7) associated with COPD-asthma overlap. Conclusions Overlap subjects have more exacerbations, less emphysema and more airway disease for any degree of lung function impairment compared to COPD alone. We identified novel genetic variants associated with this syndrome. COPD-asthma overlap is an important syndrome and may require distinct clinical management. PMID:24876173

    Endocrine function tests and a broad panel of autoantibodies to endocrine organs were assessed in 77 patients aged 5-14 years with Ullrich-Turner syndrome (UTS), who were included in the German UTS Multicenter Study. None of these patients had abnormal pituitary, thyroid or adrenocortical function, as assessed by the adequate hormone tests. Antibodies to thyroid microsomes were found in 3 of the 77 (3.9%), antibodies to thyroglobulin in 0/77, antibodies to adrenocortical cells in 1/77 (1.3%), gastric parietal cell antibodies in 2/77 (2.6%), and anterior pituitary cell antibodies in 3/77 (3.9%) probands. These prevalences were not significantly higher than those obtained in 154 age- and sex-matched normal control children when 2 control subjects were assigned to each patient with UTS. Our data do not show an increase in serological signs of endocrine autoimmunity in young patients with UTS suggesting that a putative association of these syndromes does not exist from birth and is not usually present in childhood. However, we cannot exclude the possibility that UTS is associated with factors that render these patients more susceptible to endocrine autoimmunity later in life. PMID:1306841

    The pathogenesis of thrombocytopenia associated with TAD and the occurrence of overlapping traits between TAD and AITP are still a matter of debate. For this reason, we investigated for the presence and specificity of platelet and thyroid autoantibodies in 18 TAD patients with thrombocytopenia, 19 TAD patients without thrombocytopenia and in 22 patients with primary AITP without clinical signs of TAD. Platelet-associated IgG and/or specific circulating platelet autoantibodies were detected in 83% of patients with TAD and thrombocytopenia, in 10% of patients with TAD without thrombocytopenia and in 86% of patients with primary AITP. The reactivity of serum autoantibodies, assayed by MoAb immobilization of platelet antigens (MAIPA), was directed against platelet glycoproteins Ib and/or IIb/IIIa in 50% of the patients with TAD and thrombocytopenia, as in 46% of the patients with primary AITP. Thyroid autoantibodies were found in 89% of patients with TAD and thrombocytopenia, in 95% of patients with TAD without thrombocytopenia, and in 18% of patients with primary AITP. Thyrotropin (TSH) levels determined in three of four AITP patients with thyroid autoantibodies revealed a subclinical hyperthyroidism in one patient. The present study supports the autoimmune aetiology of thrombocytopenia associated with TAD, since the prevalence and specificity of platelet autoantibodies are similar in TAD and primary AITP. The results indicate also that there exists an overlap between thyroid and platelet autoimmunity with or without clinical manifestations. PMID:9737665

    The preferential association between Turner's syndrome and congenital heart defects (CHD) have been well known since the first description by Morgagni. There are few studies about the different cardiologic problems stemming from different chromosomal patterns of X monosomies. We reviewed a large series of 136 patients with Turner syndrome without cardiologic preselection, 29 of whom had some kind of CHD (21.5%). Partial anomalous pulmonary venous drainage (PAPVD; 2.9%), aortic valve disease (stenosis and/or incompetence) (AoVD; 5. 1%), aortic coarctation (AoCo; 4.4%), and bicuspid aortic valve (BicAo; 14.7%) are much more frequent in Turner's syndrome than in the normal population, with the difference being statistically highly significant. In our cases, only the 45, X subjects showed severe CHD and multiple lesions, whereas the X-ring pattern was associated with an elevated prevalence of BicAo. Patients with X-deletion showed no signs of congenital heart malformations. Eleven patients, all with 45, X pattern, and significant CHD, underwent cardiac surgery at a mean age of 7.7 +/- 5.3 years (range 7 days-18 years) without complications. At follow-up of 3-18 years (8.6 +/- 5. 2), we were unable to observe any type of evolution of the remaining untreated cardiovascular anomalies. PMID:9986886

    Two siblings are described whose clinical presentation of cutaneous photosensitivity and central nervous system dysfunction is strongly reminiscent of the DeSanctis-Cacchione syndrome (DCS) variant of xeroderma pigmentosum. An extensive clinical evaluation supported a diagnosis of DCS and documented previously unreported findings. In vitro fibroblast studies showed UV sensitivity that was two to three times that of normal controls. However, neither a post-UV-irradiation DNA excision-repair defect indicative of XP nor a semiconservative DNA replication defect indicative of XP variant was found. Rather, a failure of RNA synthesis to recover to normal levels after UV exposure was observed, a biochemical abnormality seen in Cockayne syndrome (CS), one of the premature-aging syndromes with clinical UV sensitivity. These patients, therefore, clinically have XP, but their biochemical characteristics suggest CS. The reason(s) for the severe neurologic disease, in light of the relatively mild cutaneous abnormalities, is unclear. Other cases with unusual fibroblast responses to irradiation have been noted in the literature and, along with the data from our patients, reinforce the notion of the complexity of DNA maintenance and repair.

    The discovery of JAK2 (V617F) a decade ago led to optimism for a rapidly developing treatment revolution in Ph(-) myeloproliferative neoplasms. Unlike BCR-ABL, however, JAK2 was found to have a more heterogeneous role in carcinogenesis. Therefore, for years, development of new therapies was slow, despite standard treatment options that did not address the overwhelming symptom burden in patients with primary myelofibrosis (MF), post-essential thrombocythemia MF, post-polycythemia vera MF, and myelodysplastic syndrome (MDS)/myeloproliferative neoplasm (MPN) syndromes. JAK-STAT inhibitors have changed this, drastically ameliorating symptoms and ultimately beginning to show evidence of impact on survival. Now, the genetic foundations of myelofibrosis and MDS/MPN are rapidly being elucidated and contributing to targeted therapy development. This has been empowered through updated response criteria for MDS/MPN and refined prognostic scoring systems in these diseases. The aim of this article is to summarize concisely the current and rationally designed investigational therapeutics directed at JAK-STAT, hedgehog, PI3K-Akt, bone marrow fibrosis, telomerase, and rogue epigenetic signaling. The revolution in immunotherapy and novel treatments aimed at previously untargeted signaling pathways provides hope for considerable advancement in therapy options for those with chronic myeloid disease.

    Autoimmune phenomena are common in patients with chronic hepatitis C. Management of chronic hepatitis C/autoimmune hepatitis syndrome has until recently been problematic due to the adverse effects of interferon on autoimmune processes and immunosuppression on viral replication. In this report we describe 3 patients with chronic hepatitis C/autoimmune hepatitis overlap syndrome who responded rapidly to direct acting anti-viral therapy. The resolution of the autoimmune process supports a direct viral role in its pathophysiology. PMID:27190580

    In this case report, neuroleptic malignant syndrome (NMS) in an elderly patient with normal pressure hydrocephalus overlapping corticobasal degeneration was reported. The case highlights the need for clinicians to be cautious when using dopaminergic medication in the elderly patients, since these agents have risks for NMS which is a life-threatening complication. Additionally, co-occurrence of primary and secondary parkinsonian dementia syndromes should be kept in mind to avoid additional complications in the elderly patients. PMID:25280791

    Turner syndrome (TS) is a common genetic disorder in females associated with the absence of complete or parts of a second sex chromosome. In 5-12% of patients, mosaicism for a cell line with a normal or structurally abnormal Y chromosome is identified. The presence of Y-chromosome material is of medical importance because it results in an increased risk of developing gonadal tumours and virilisation. Molecular study and fluorescence in situ hybridisation approaches were used to study 74 Brazilian TS patients in order to determine the frequency of hidden Y-chromosome mosaicism, and to infer the potential risk of developing malignancies. Additionally, we describe one TS girl with a very uncommon karyotype 46,X,der(X)t(X;Y)(p22.3?2;q11.23) comprising a partial monosomy of Xp22.3?2 together with a partial monosomy of Yq11.23. The presence of cryptic Y-chromosome-specific sequences was detected in 2.7% of the cases. All patients with Y-chromosome-positive sequences showed normal female genitalia with no signs of virilisation. Indeed, the clinical data from Y-chromosome-positive patients was very similar to those with Y-negative results. Therefore, we recommend that the search for hidden Y-chromosome mosaicism should be carried out in all TS cases and not be limited to virilised patients or carriers of a specific karyotype.

    Turner syndrome (TS) is a genetic condition that permits direct investigation of the complex interaction among genes, hormones, behavior, and brain development. Here, we used automated segmentation and surface-based morphometry to characterize the differences in brain morphology in children (n = 30) and adolescents (n = 16) with TS relative to age- and sex-matched control groups (n = 21 and 24, respectively). Our results show that individuals with TS, young and adolescent, present widespread reduction of gray matter volume, white matter volume and surface area (SA) over both parietal and occipital cortices bilaterally, as well as enlarged amygdala. In contrast to the young cohort, adolescents with TS showed significantly larger mean cortical thickness and significantly smaller total SA compared with healthy controls. Exploratory developmental analyses suggested aberrant regional brain maturation in the parahippocampal gyrus and orbitofrontal regions from childhood to adolescence in TS. These findings show the existence of abnormal brain morphology early in development in TS, but also suggest the presence of altered neurodevelopmental trajectories in some regions, which could potentially be the consequences of estrogen deficiency, both pre- and postnatally.

    Turner syndrome is one of the most common cytogenetic abnormalities. It is known that the Y chromosome or Y derived material is present in 6-9% of TS patient and it may develop a high risk of gonadoblastoma in 15-25%. So it is crucial to carry out cyto genetic analysis and Y-specific probe studies for all persons with gonadal dysgenesis to rule out mosaicism with Y-bearing cell line; eg 45,X/46,XY. In this study, 26 archival slides previously analyzed cytogenetically as 45,X, 45,X/46,X,i(X), 45,X/46,X,r(X), and 45,X/46,XX were examined. Coamplification PCR, having the advantage of providing rapid result and confirming PCR failure, was performed with the slide samples in the regions of dystrophin gene in Xp21and DYZ3 in the Y centromeric region. All of archived slides were positive for X-specific gene and one slide of 45,X was found to have the cryptic Y chromosome material. Our result suggests that the archived cytogenetic slides could be applied for the detection of Y chromosome rapidly and efficiently in TS patients. PMID:10762060

    The purpose of this study is to evaluate the trends in age and anthropometric data for girls with Turner syndrome (TS) at start of growth hormone (GH) treatment in Japan. The data for analysis were obtained from a retrospective cohort, the Foundation for Growth Science, Japan. We analyzed trends in starting age of GH treatment for girls with TS in Japan after dividing subjects (n=1,478) into three registration periods: 1991-1994, 1995-1999 and 2000-2004. We also assessed the ratio of the subpopulation of subjects under five years of age. As results, the mean age (standard deviation (SD)) at start of GH treatment was significantly different among the three groups (10.95 (3.63), 10.15 (3.39) and 8.78 (3.61), p<0.0001). The proportion of the subjects under five years of age increased significantly over time (5.11%, 7.11% and 16.85%, p<0.0001). Mean (SD) height SD scores were also significantly different (-3.41 (0.87), -3.26 (0.81) and -3.17 (0.79), p<0.0001). However, the proportions of the karyotype of 45,X were not significantly different among the three groups (p=0.25). We concluded that age and shortness at initiation of GH treatment had been improving over time. However, these favorable trends have not fully met the conditions recommended by international clinical guidelines for TS. PMID:18753703

    Objective To report the clinical, radiological, and immunological association of demyelinating disorders with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis. Methods Clinical and radiological analysis of a cohort of 691 patients with anti-NMDAR encephalitis. Determination of antibodies to NMDAR, aquaporin-4 (AQP4) and myelin oligodendrocyte glycoprotein (MOG) was performed using brain immunohistochemistry and cell-based assays. Results Twenty-three of 691 patients with anti-NMDAR encephalitis had prominent MRI and/or clinical features of demyelination. Group 1 included 12 patients in whom anti-NMDAR encephalitis was preceded or followed by independent episodes of NMO-spectrum disorder (5 cases, 4 anti-AQP4-positive), or brainstem or multifocal demyelinating syndromes (7 cases, all anti-MOG-positive). Group 2 included 11 patients in whom anti-NMDAR encephalitis occurred simultaneously with MRI and symptoms compatible with demyelination (5 AQ4-positive, 2 MOG-positive). Group 3 (136 controls) included 50 randomly selected patients with typical anti-NMDAR encephalitis, 56 with NMO, and 30 with multiple sclerosis: NMDAR-antibodies were detected only in the 50 anti-NMDAR patients, MOG-antibodies in 3/50 anti-NMDAR and 1/56 NMO patients, and AQP4-antibodies in 48/56 NMO and 1/50 anti-NMDAR patients (p<0.0001 for all comparisons with Groups 1 and 2). Most patients improved with immunotherapy, but compared with anti-NMDAR encephalitis the demyelinating episodes required more intensive therapy and resulted in more residual deficits. Only 1/23 NMDAR patients with signs of demyelination had ovarian teratoma compared with 18/50 anti-NMDAR controls (p=0.011) Interpretation Patients with anti-NMDAR encephalitis may develop concurrent or separate episodes of demyelinating disorders, and conversely patients with NMO or demyelinating disorders with atypical symptoms (e.g., dyskinesias, psychosis) may have anti-NMDAR encephalitis.

    Individuals with chronic obstructive pulmonary disease (COPD) and asthma are an important but poorly characterised group. The genetic determinants of COPD and asthma overlap have not been studied. The aim of this study was to identify clinical features and genetic risk factors for COPD and asthma overlap. Subjects were current or former smoking non-Hispanic whites or African-Americans with COPD. Overlap subjects reported a history of physician-diagnosed asthma before the age of 40 years. We compared clinical and radiographic features between COPD and overlap subjects. We performed genome-wide association studies (GWAS) in the non-Hispanic whites and African-American populations, and combined these results in a meta-analysis. More females and African-Americans reported a history of asthma. Overlap subjects had more severe and more frequent respiratory exacerbations, less emphysema and greater airway wall thickness compared to subjects with COPD alone. The non-Hispanic white GWAS identified single nucleotide polymorphisms in the genes CSMD1 (rs11779254, p=1.57 × 10(-6)) and SOX5 (rs59569785, p=1.61 × 10(-6)) and the meta-analysis identified single nucleotide polymorphisms in the gene GPR65 (rs6574978, p=1.18 × 10(-7)) associated with COPD and asthma overlap. Overlap subjects have more exacerbations, less emphysema and more airway disease for any degree of lung function impairment compared to COPD alone. We identified novel genetic variants associated with this syndrome. COPD and asthma overlap is an important syndrome and may require distinct clinical management. PMID:24876173

    Aims: To determine the frequency of C677T and A1298C polymorphisms of the MTHFR gene and correlate them with homocysteine serum levels in patients with Turner syndrome (TS) and controls. Methods: This case–control study included 78 women with TS and a control group of 372 healthy individuals without personal or family history of cardiovascular disease and cancer. C677T (rs1801133) and A1298C (rs1801131) polymorphisms were detected by polymerase chain reaction–restriction fragment-length polymorphism and the TaqMan system, respectively. Homocysteine serum levels were determined by high-performance liquid chromatography. The results were analyzed statistically, and p<0.05 was considered to represent a significant difference. Results: The homocysteine levels change was 13.9+3.3 nM in patients with TS and 8.8+3.2 nM in the control group. No significant difference between groups was found (p=0.348). Single-marker analysis revealed no association between MTHFR C677T polymorphism and TS when genotype (p=0.063) or allelic (p=0.277) distribution was considered. Regarding MTHFR A1298C polymorphism, a statistical difference was found between the TS group and the control group, for both genotype (p<0.0001) and allele (p<0.0001) distribution. Haplotype analysis of 2 MTHFR polymorphisms identified 2 haplotypes—CC and TC—associated with TS (p<0.001 and p=0.0165, respectively). However, homocysteine levels were not higher in patients with haplotype risk. Conclusion: The results suggest that the C677T and A1298C polymorphisms of the MTHFR gene are not related to homocysteine levels in Brazilian patients with TS, despite the differential distribution of the mutated allele C (A1298C) in these patients. Further studies are needed to investigate the possible genetic interaction with homocysteine levels in TS. PMID:22283972

    Antibodies against the Na/I symporter (anti-NIS ab) have been found in adult patients with autoimmune thyroid diseases. As easily available for the immune system, NIS can play a role in the initial stage of autoimmune thyroid diseases. Children with Turner's syndrome (TS) being at high risk of autoimmune thyroid disease development seem a valuable group for the investigation of the early autoimmune process. The aim of the study was to investigate the presence of anti-NIS ab and its potential clinical significance in TS children. Fifty four girls with TS were examined (age 11.9 ± 2.46 years), and 23 healthy girls with normal thyroid function, free of autoimmune diseases. Anti-NIS antibodies were measured by the in-house ELISA method and the Western blotting. Sera considered positive for anti-NIS ab were used for the iodide uptake bioassay using COS7 cells stably transfected with hNIS. In all patients the thyroid function, antithyroid antibodies presence and thyroid ultrasonography were evaluated. In 20% of the patients a subclinical hypothyroidism was diagnosed and 70.4% had antithyroid antibodies (anti-TPO - 64.8% and Anti-Tg - 24%). Anti-NISab were present in 14.8% girls with TS and in none of the control group. Their presence was unrelated to other antithyroid antibodies titre or patients' age. A positive correlation between the anti-NIS ab presence and the hypothyroidism was found (p < 0.04). Anti-NIS ab-positive sera did not suppress iodine uptake. In conclusion, anti-NIS antibodies were present in 14.8% of children with TS and they were related to the presence of hypothyroidism. PMID:22836628

    We describe the cytogenetic evolution of multiple cell lines in the gonadal tissue of a 10-year-old girl with mosaic Ullrich-Turner syndrome (UTS) involving clonal telomeric associations (tas) of the Y chromosome. G-band analysis of all tissues showed at least 2 cell lines; 45,X and 46,X,tas(Y;21)(q12;p13). However, analysis of left gonadal tissue of this patient showed the evolution of 2 additional cell lines, one designated 45,X,tas(Y;21)(q12;p13),-22 and the other 46,X,tas(Y;21)(q12;p13),+tas(Y;14)(q12;p13),-22. Fluorescence in situ hybridization (FISH) analysis of interphase nuclei from uncultured gonadal tissue confirmed the findings of aneuploidy in the left gonadal tissue and extended the findings of aneuploidy to the tissue of the right gonad. The chromosome findings in the gonadal tissue of this patient suggest a preneoplastic karyotype relating to several distinct tumor associations. The clonal evolution of telomeric fusions indicates chromosome instability and suggests the extra copy of the Y chromosome may have resulted from a fusion-related malsegregation. In addition, the extra Y suggests low-level amplification of a putative gonadoblastoma gene, while the loss of chromosome 22 suggests the loss of heterozygosity for genes on chromosome 22. This case demonstrates the utility of the study of gonadal tissue in 45X46,XY UTS patients, and provides evidence that clonal telomeric fusions may, in rare cases, be associated with chromosomal malsegregation and with the subsequent evolution of unstable karyotypes. 27 refs., 3 figs.

    Turner syndrome (TS) arises from partial or complete absence of the X-chromosome in females. Girls with TS show deficits in visual-spatial skills as well as reduced brain volume and surface area in the parietal cortex which supports these cognitive functions. Thus, measuring the developmental trajectory of the parietal cortex and the associated visual-spatial cognition in TS may provide novel insights into critical brain-behavior associations. In this longitudinal study, we acquired structural MRI data and assessed visual-spatial skills in 16 (age: 8.23 ± 2.5) girls with TS and 13 age-matched controls over two time-points. Gray and white matter volume, surface area and cortical thickness were calculated from surfaced based segmentation of bilateral parietal cortices, and the NEPSY Arrows subtest was used to assess visual-spatial ability. Volumetric and cognitive scalars were modeled to obtain estimates of age-related change. The results show aberrant growth of white matter volume (P = 0.011, corrected) and surface area (P = 0.036, corrected) of the left superior parietal regions during childhood in girls with TS. Other parietal sub-regions were significantly smaller in girls with TS at both time-points but did not show different growth trajectories relative to controls. Furthermore, we found that visual-spatial skills showed a widening deficit for girls with TS relative to controls (P = 0.003). Young girls with TS demonstrate an aberrant trajectory of parietal cortical and cognitive development during childhood. Elucidating aberrant neurodevelopmental trajectories in this population is critical for determining specific stages of brain maturation that are particularly dependent on TS-related genetic and hormonal factors.

    To evaluate the anthropometric features of girls with Turner syndrome (TS) at birth and presentation and the effect of karyotype on these parameters. Data were collected from 842 patients with TS from 35 different centers, who were followed-up between 1984 and 2014 and whose diagnosis age ranged from birth to 18 years. Of the 842 patients, 122 girls who received growth hormone, estrogen or oxandrolone were excluded, and 720 girls were included in the study. In this cohort, the frequency of small for gestational age (SGA) birth was 33%. The frequency of SGA birth was 4.2% (2/48) in preterm and 36% (174/483) in term neonates (P < 0.001). The mean birth length was 1.3 cm shorter and mean birth weight was 0.36 kg lower than that of the normal population. The mean age at diagnosis was 10.1 ± 4.4 years. Mean height, weight and body mass index standard deviation scores at presentation were -3.1 ± 1.7, -1.4 ± 1.5, and 0.4 ± 1.7, respectively. Patients with isochromosome Xq were significantly heavier than those with other karyotype groups (P = 0.007). Age at presentation was negatively correlated and mid-parental height was positively correlated with height at presentation. Mid-parental height and age at presentation were the only parameters that were associated with height of children with TS. The frequency of SGA birth was found higher in preterm than term neonates but the mechanism could not be clarified. We found no effect of karyotype on height of girls with TS, whereas weight was greater in 46,X,i(Xq) and 45,X/46,X,i(Xq) karyotype groups. © 2016 Wiley Periodicals, Inc. PMID:26788866

    Turner's syndrome (TS) has been documented as the most common cause of aortic dissection in young women. However, little attention from vascular surgery has been paid to these patients. We report the first case of ruptured type B aortic dissection with aberrant right subclavian artery treated successfully with hybrid endovascular and open procedures in a patient with TS. Left carotid to subclavian artery bypass, thoracic endovascular aortic repair, and coil embolization of the aberrant right subclavian and left subclavian arteries were performed in an emergency setting. Literature on epidemiology, causes, and management options of acute aortic dissection in TS patients are reviewed and discussed. PMID:24011806

    A 10-year-old girl with Ullrich-Turner syndrome was found to have the novel karyotype 45,X/46,X,r(X)(p11q11)/46,X,dic(X)(p11). Fluorescence in situ hybridization (FISH) with the {alpha} satellite X centromere probe established the origin of the small ring chromosome. Scanning a large number of cells by interphase FISH showed that the dicentric (X) was the least prevalent cell line. The common breakpoint of Xp11 suggests a sequence of errors as the mechanism whereby these 3 distinct cell lines have arisen. 11 refs., 4 figs., 1 tab.

    We present four cases of adults with obstructive sleep apnea in whom positive airway pressure therapy alone failed to provide adequate oxygenation. We have previously reported the use of dual mask for ventilatory support of a patient postoperatively (Porhomayon et al., 2013). Here, we report an evaluation of the dual mask in four patients with overlap syndromes. Application of dual mask provided adequate oxygenation with lower continuous positive airway pressure (CPAP)/bilevel positive airway pressure (BIPAP) pressure levels. PMID:23970903

    Objectives To measure the prevalence, predictors and post-hospitalization outcomes associated with the overlap syndrome of coexisting depression and incident delirium in older hospitalized patients. Design Secondary analysis of prospective cohort data from the control group of the Delirium Prevention Trial. Setting General medical service of an academic medical center. Follow-up interviews at one month and one year post-hospital discharge. Participants Four hundred and fifty nine patients aged 70 and over who were not delirious at hospital admission. Measurements Depressive symptoms assessed at hospital admission using the 15-item Geriatric Depression Scale (cutoff score of 6 used to define depression), daily assessments of incident delirium from admission to discharge using the Confusion Assessment Method. Activities of daily living at admission and one month post-discharge. New nursing home placement and mortality determined at one year. Results Of 459 participants, 23 (5%) had the overlap syndrome, 39 (9%) delirium alone, 121 (26%) depression alone and 276 (60%) neither condition. In adjusted analysis, patients with the overlap syndrome had higher odds of new nursing home placement or death at one year (adjusted odds ratio [AOR] 5.38, 95% confidence interval [CI] = 1.57– 18.38) and one month functional decline (AOR 3.30, 95% CI = 1.14–9.56) compared to patients with neither condition. Conclusion The overlap syndrome of depression and delirium is associated with significant risk of functional decline, institutionalization and death. Efforts to identify, prevent and treat this condition may reduce the risk of adverse outcomes in older hospitalized patients. PMID:19558475

  13. Chronic obstructive pulmonary disease and obstructive sleep apnoea—the overlap syndrome

    PubMed Central

    2016-01-01

    Chronic obstructive pulmonary disease (COPD) and obstructive sleep apnoea (OSA) are highly prevalent disorders and the co-existence of both disorders, termed the overlap syndrome, affects at least 1% of the adult population. Patients with the overlap syndrome typically experience more pronounced nocturnal oxygen desaturation and there is a high prevalence of pulmonary hypertension in such patients. Recent evidence suggests that the prevalence of each disorder together is higher than might be predicted by simple prevalence statistics, although the evidence is not clear-cut in this regard. Sleep itself can have several negative effects in patients with COPD. Sleep quality is diminished with reduced amounts of slow wave and rapid-eye-movement (REM) sleep, which may contribute to daytime symptoms such as fatigue and lethargy. Furthermore, normal physiological adaptations during sleep that result in mild hypoventilation in normal subjects are more pronounced in COPD, which can result in clinically important nocturnal oxygen desaturation. Management of sleep disorders in patients with COPD should address both sleep quality and disordered gas exchange. Non-invasive pressure support is beneficial in selected cases, particularly during acute exacerbations associated with respiratory failure, and is particularly helpful in patients with the overlap syndrome. There is limited evidence of benefit from pressure support in the chronic setting in COPD patients without OSA. PMID:26904264

  14. Gene localisation for Wilson-Turner syndrome (WTS:MIM 309585)

    1996-07-12

    The gene for this syndrome of X-linked mental retardation with gynecomastia, obesity, speech difficulties, tapering fingers and small feet was mapped between Xp21.1 and Xq22. Linkage to DXS255 at Xp11 was firmly established, with no recombination. Subsequent characterization of numerous microsatellite markers and development of the background genetic map in this region of the X chromosome has enabled significant reduction to the localization of the gene for WTS in the one family so far reported. The new linkage data were obtained as described previously and are presented in Table I. The closest flanking markers are DXS426 at Xp11.3 and DXS990 at Xq21.3. The regional localization is significantly reduced from the previous interval of 66 cM to an interval of 25 cM. The maximum two-point lod score is now 6.07 at AR. 6 refs., 1 tab.

    Objective To preliminarily study the feasibility of oocyte cryopreservation in post-pubertal girls aged between 13 and 15 years who were at risk for premature ovarian failure due to the accelerated follicle loss associated with Turner’s Syndrome or cancer treatments. Design Retrospective cohort and review of literature. Setting Academic fertility preservation unit. Participants Three girls diagnosed with Turner syndrome, one girl diagnosed with germ-cell tumor and one girl diagnosed with lymphoblastic leukemia. Interventions Assessment of ovarian reserve, ovarian stimulation, oocyte retrieval, in vitro maturation, and mature oocyte cryopreservation. Main Outcome Measure Response to ovarian stimulation, number of mature oocytes cryopreserved and complications, if any. Results Mean AMH, baseline FSH, Estradiol and antral follicle counts were 1.30 ± 0.39, 6.08 ± 2.63, 41.39 ± 24.68, 8.0 ± 3.2; respectively. In Turner girls the ovarian reserve assessment indicated already diminished ovarian reserve. Ovarian stimulation and oocyte cryopreservation was successfully performed in all female children referred for fertility preservation. A range of 4–11 mature oocytes (mean 8.1 ± 3.4) was cryopreserved without any complications. All girls tolerated the procedure well. Conclusions Oocyte cryopreservation is a feasible technique in selected female children at risk for premature ovarian failure. Further studies would be beneficial to test the success of oocyte cryopreservation in young girls. PMID:25214440

    Several studies indicate a significant degree of overlap between irritable bowel syndrome (IBS) and gastroesophageal reflux disease (GERD). Likewise, both functional heartburn (FH) and IBS are functional digestive disorders that may occur in the same patients. However, data establishing a solid link between FH and IBS are lacking, mainly because the clinical definition of FH has undergone substantial changes over the years. The available literature on the overlap between GERD or FH and IBS highlights considerable heterogeneity in terms of the criteria and diagnostic procedures used to assess heartburn and IBS. In particular, several epidemiological studies included patients with concomitant IBS and GERD without any attempt to distinguish FH (as defined by the Rome III criteria) from GERD via pathophysiological investigations. Independent of these critical issues, there is preliminary evidence supporting a significant degree of FH-IBS overlap. This underscores the need for studies based on updated diagnostic criteria and accurate pathophysiological classifications, particularly to distinguish FH from GERD. This distinction would represent an essential starting point to achieving a better understanding of pathophysiology in the subclasses of patients with GERD and FH and properly assessing the different degrees of overlap between IBS and the subcategories of heartburn.The present review article intends to appraise and critically discuss current evidence supporting a possible concomitance of GERD or FH with IBS in the same patients and to highlight the pathophysiological relationships between these disorders.

  17. Respiratory mechanics and ventilatory control in overlap syndrome and obesity hypoventilation

    PubMed Central

    2013-01-01

    The overlap syndrome of obstructive sleep apnoea (OSA) and chronic obstructive pulmonary disease (COPD), in addition to obesity hypoventilation syndrome, represents growing health concerns, owing to the worldwide COPD and obesity epidemics and related co-morbidities. These disorders constitute the end points of a spectrum with distinct yet interrelated mechanisms that lead to a considerable health burden. The coexistence OSA and COPD seems to occur by chance, but the combination can contribute to worsened symptoms and oxygen desaturation at night, leading to disrupted sleep architecture and decreased sleep quality. Alveolar hypoventilation, ventilation-perfusion mismatch and intermittent hypercapnic events resulting from apneas and hypopneas contribute to the final clinical picture, which is quite different from the “usual” COPD. Obesity hypoventilation has emerged as a relatively common cause of chronic hypercapnic respiratory failure. Its pathophysiology results from complex interactions, among which are respiratory mechanics, ventilatory control, sleep-disordered breathing and neurohormonal disturbances, such as leptin resistance, each of which contributes to varying degrees in individual patients to the development of obesity hypoventilation. This respiratory embarrassment takes place when compensatory mechanisms like increased drive cannot be maintained or become overwhelmed. Although a unifying concept for the pathogenesis of both disorders is lacking, it seems that these patients are in a vicious cycle. This review outlines the major pathophysiological mechanisms believed to contribute to the development of these specific clinical entities. Knowledge of shared mechanisms in the overlap syndrome and obesity hypoventilation may help to identify these patients and guide therapy. PMID:24256627

    2015-12-01

    Dubowitz syndrome is a presumed autosomal recessive disorder characterized by multiple congenital abnormalities: microcephaly, learning and developmental delay, growth failure, and a predisposition to allergies and eczema. There have been more than 150 individuals reported to have this diagnosis, but no unifying genetic alteration has been identified indicating genetic heterogeneity. We report on a pair of monozygotic twins diagnosed clinically with Dubowitz syndrome by Professor Dubowitz over 30 years ago and identified to have a de novo heterozygous 3.2-Mb deletion at 19q13.11q13.12. Exome sequencing did not identify either a putative pathogenic variant on the trans allele supporting recessive inheritance or any other causative sequence variants. Comparison of the phenotype in our cases shows considerable overlap with the 19q13.11 microdeletion syndrome, suggesting that a subset of individuals diagnosed with Dubowitz syndrome may be due to deletions at 19q13. Our finding further reinforces the genetic and phenotypic heterogeneity of Dubowitz syndrome. PMID:26377242

    The debate about whether asthma and chronic obstructive pulmonary disease (COPD) are distinct clinical syndromes is not new; there is heightened interest in understanding the group of individuals with obstructive lung disease who seem to have elements of both conditions because recent studies have demonstrated increased risk for respiratory events and exacerbations. We describe the clinical characteristics of this subtype of disease and suggest 4 working definitions of individuals who would fall into the asthma-COPD overlap category. Understanding the mechanisms underlying these subtypes will hopefully lead into a better understanding of therapeutic strategies that can target specific pathobiologic pathways. PMID:27401623

    We describe a child with downslanting palpebral fissures, preauricular malfunctions, congenital heart defect (total anomalous pulmonary venous return), unilateral absence of a kidney, and developmental delay with an apparent interstitial duplication of proximal 22q. Fluorescent in situ hybridization (FISH) analysis showed duplication of the IGLC locus, and C-banding of the duplicated region was negative. The duplication appears to involve 22q11.2-q12. Although the child has neither colobomas nor microphthalmia, he shows phenotypic overlap with with the cat eye syndrome, which is caused by a supernumerary bisatellited chromosome arising from inverted duplication of the short arm and proximal long arm of chromosome 22. Further molecular studies of this patient should help to define the regions responsible for the manifestations of cat eye syndrome. 17 refs., 3 figs., 1 tab.

    Clinical overlap makes the diagnosis of overgrowth syndromes challenging. Clinical overlap exists between Simpson-Golabi-Behmel syndrome (SGBS) and Beckwith-Wiedemann syndrome (BWS) which share pre- and postnatal overgrowth, macroglossia, umbilical hernia, organomegaly, ear lobe creases, and occurrence of embryonal tumors as characteristic features. Based on the clinical history of a patient, who was diagnosed with BWS shortly after birth and reassessed and rediagnosed with SGBS at age 21 years, particular attention should be paid to developing facial dysmorphia. In addition, we delineate further clinical findings that may allow differentiation between both conditions. PMID:25339544

    The recognition that there are some patients with features of asthma and chronic obstructive pulmonary disease (COPD) has highlighted the need to develop more specific treatments for these clinical phenotypes. Some patients with COPD have predominantly eosinophilic inflammation and might respond to high doses of inhaled corticosteroids and newly developed specific antieosinophil therapies, including blocking antibodies against IL-5, IL-13, IL-33, and thymic stromal lymphopoietin, as well as oral chemoattractant receptor-homologous molecule expressed on TH2 cells antagonists. Other patients have severe asthma or are asthmatic patients who smoke with features of COPD-induced inflammation and might benefit from treatments targeting neutrophils, including macrolides, CXCR2 antagonists, phosphodiesterase 4 inhibitors, p38 mitogen-activating protein kinase inhibitors, and antibodies against IL-1 and IL-17. Other patients appear to have largely fixed obstruction with little inflammation and might respond to long-acting bronchodilators, including long-acting muscarinic antagonists, to reduce hyperinflation. Highly selected patients with severe asthma might benefit from bronchial thermoplasty. Some patients with overlap syndromes can be conveniently treated with triple fixed-dose combination inhaler therapy with an inhaled corticosteroid, long-acting β2-agonist, and long-acting muscarinic antagonist, several of which are now in development. Corticosteroid resistance is a feature of asthma-COPD overlap syndrome, and understanding the various molecular mechanisms of this resistance has identified novel therapeutic targets and presented the prospect of therapies that can restore corticosteroid responsiveness.

    Background Studies of copy number variation (CNV) have successfully characterized loci and molecular pathways involved in a range of neuropsychiatric conditions. We conducted an analysis of rare CNVs in Tourette Syndrome (TS) to identify novel risk regions and relevant molecular pathways, evaluate the burden of structural variation in cases versus controls, and to assess the overlap of identified variations with those implicated in other neuropsychiatric syndromes. Methods We conducted a case-control study of 460 individuals with TS, including 148 parent-child trios and 1131 controls. CNV analysis was undertaken using 370K to 1M probe arrays, and genome-wide genotyping data was used to match cases and controls for ancestry. Transmitted and de novo CNVs present in < 1% of the population were evaluated. Results While there was no significant increase in the number of de novo or transmitted rare CNVs in cases versus controls, pathway analysis using multiple algorithms showed enrichment of genes within histamine receptor (H1R and H2R) signaling pathways (p=5.8×10-4-1.6×10-2) as well as “axon guidance”, “cell adhesion”, “nervous system development” and “synaptic structure and function” processes. Genes mapping within rare CNVs in TS showed significant overlap with those previously identified in autism spectrum disorders (ASD), but not intellectual disability or schizophrenia. Three large, likely-pathogenic, de novo events were identified, including one disrupting multiple gamma-Aminobutyric acid (GABA) receptor genes. Conclusions We identify further evidence supporting recent findings regarding the involvement of histaminergic and GABAergic mechanisms in the etiology of TS and show an overlap of rare CNVs in TS and ASD.

    2013-01-01

    Turner syndrome (TS) is one of the most common chromosomal abnormalities, with an estimated frequency among female live births of 1/2,000-3,000. The syndrome is characterized by the partial or complete absence of one X chromosome (45,X karyotype). We reported a unique case of a 40-year-old woman with TS accompanying unexpected elongated styloid process specific to Eagle syndrome (ES) and followed up-prolactinoma. The present article is the first report to define the cone-beam computed tomographic (CBCT) features of TS accompanying ES. Patients with TS carry various risks that make treatment more complicated; thus advanced imaging techniques for proper treatment and follow-up are extremely important. In the light of CBCT examination, craniofacial abnormalities specific to TS and accompanying syndromes such as the crowding of teeth especially in the maxillary anterior region caused by maxillary narrowness, micrognatic maxilla and mandible, relative mandibular retrusion, malocclusion, open-bite, and an elongated styloid process (length of 32.7 mm) on the right side were illustrated in detail.

    Background Depression and frailty both predict disability and morbidity in later life. However, it is unclear to what extent these common geriatric syndromes represent overlapping constructs. Objective To examine the joint relationship between the constructs of depression and frailty. Methods Data come from 2004/5 wave of the Baltimore Epidemiologic Catchment Area Study and analysis is limited to participants aged 40 and older with complete data on frailty and depression indicators (N = 683). Depression was measured using the Diagnostic Interview Schedule and frailty was indexed by modified Fried criteria. A series of confirmatory latent class analyses (LCA) were used to assess the degree to which depression and frailty syndromes identify the same populations. A latent Kappa coefficient (Кl) was also estimated between the constructs. Results Confirmatory LCA indicated that depression and frailty represent distinct syndromes rather than a single construct. The joint modeling of the two constructs supported a three class solution for depression and two class solution for frailty, with 2.9% categorized as severe depression, 19.4% as mild depression, and 77.7% as not depressed, and 21.1% categorized as frail and 78.9% as not frail. The chance-corrected agreement statistic indicated moderate correspondence between the depression and frailty constructs (Кl: 66, 95% CI: 0.58 – 0.74). Conclusions Results suggest that depression and frailty are interrelated concepts, yet their operational criteria identify substantively overlapping subpopulations. These findings have implications for understanding factors that contribute to the etiology and prognosis of depression and frailty in later life. PMID:23567406
