OBJECTIVES: The technique of subcoronary autograft implantation for the Ross procedure has shown excellent durability of aortic valve function in adults. However, its use in children with hypoplastic aortic annulus or multilevel left ventricular outflow tract obstruction (LVOTO) was traditionally precluded. We combined this technique with a Konno incision and evaluated LVOTO relief and durability of the autograft function in growing patients. METHODS: Between January 2012 and January 2017, 13 patients with severe LVOTO and hypoplastic aortic annulus underwent Ross-Konno procedure with subcoronary autograft implantation...

BACKGROUND: Turner syndrome (TS) appears in women as a result of the lack of part or the whole of one of the X chromosomes. It is characterized by the occurrence of low height, hypogonadism, numerous developmental defects, and is often accompanied by psychological disturbances. OBJECTIVES: Although the phenotype characteristics of women with TS are quite well documented, the knowledge of the impact of Turner syndrome on the satisfaction with life is still insufficient...

Turner syndrome, characterized by the presence of a monosomy X cell line, is a common chromosomal disorder. Patients with Turner syndrome are usually phenotypically female, and male cases are rarely reported. Here, we report a fetus with a mosaic karyotype: mos 45,X/46,X,del(Y)(q11.21). The fetus was initially misdiagnosed as female with Turner syndrome by both noninvasive prenatal testing and cytogenetic analysis of amniotic fluid and was subsequently found to have male anatomy by antenatal ultrasonography at 24 weeks gestational age...

The reported prevalence of complications in Turner Syndrome (TS) was highly variable because of the rarity and the limited numbers analyzed. Again, possible presence of other complications that are not described as specific for TS, is also speculated. To resolve these issues, a questionnaire survey was conducted in hGH treated 492 patients with adult TS (17-42 years). The possible association with these complications and karyotypes were also analyzed. The complications and their prevalence were as follows: chronic thyroiditis (25...

BACKGROUND: Whilst the dangers of 'legal highs' have been widely publicised in the media, very few cases of the neurological syndrome associated with the inhalation of nitrous oxide (N2 O) have been reported. Here we set out to raise awareness of subacute degeneration of the spinal cord arising from recreational N2 O use so that formal surveillance programs and public health interventions can be designed. METHODS: Case series documenting the clinical and investigational features of ten consecutive cases of subacute degeneration of the spinal cord presenting to a hospital with a tertiary neurosciences service in East London...

Fertility preservation therapies can conserve future reproductive potential for persons facing serious medical diagnoses. With cure rates for childhood cancer reaching almost 80%, quality-of-life concerns for long-term survivors, including future parenting, are becoming more pertinent. Late effects of childhood cancer can be divided into physical, social, psychological, and spiritual domains. Potential loss of fertility threatens the well-being of these children in all these domains. Providers often hesitate to discuss fertility preservation with the patients...

Background: Constitutional ring chromosomes are rare orphan chromosomal disorders. Ring chromosome syndrome featuring growth retardation and mild to intermediate intellectual disability is likely caused by the dynamic behavior of ring chromosome through cell cycles. Chromosomal and regional specific phenotypes likely result from segmental losses and gains during the ring formation. Although recent applications of genomic copy number and sequencing analyses revealed various ring chromosome structures from an increasing number of case studies, there was no organized effort for compilating and curating cytogenomic and clinical finding for ring chromosomes...

Objective: Patients with Turner syndrome (TS) are at increased risk for metabolic disorders. We aimed to delineate the occurrence and evolution of metabolic comorbidities in TS patients and to determine whether these differ in 45,X monosomy and other karyotypes. Methods: A longitudinal and cross-sectional retrospective cohort study was conducted in a tertiary pediatric endocrine unit during 1980-2016. Ninety-eight TS patients, 30 with 45,X monosomy were followed from childhood to early adulthood...

Objective: Estrogen replacement therapy (ERT) for Turner syndrome (TS) is a widely discussed topic; however, the optimal model of ERT for patients with delayed diagnosis and/or initiation of therapy is still unclear, mainly due to insufficient data. We present the results of a prospective observational single-center study in which the efficacy of late-onset puberty induction by one-regimen transdermal ERT in TS girls was evaluated. Methods: The analysis encompassed 49 TS girls (63...

Establishing whether miscarriages result from fetal aneuploidy or other factors is important for treating recurrent pregnancy loss. We examined the relationship between fetal heart rate (FHR) before miscarriage in the early first trimester and fetal karyotype, analyzing 223 pregnant women with recurrent pregnancy loss. Among the pregnancies, 110 resulted in live births regarded as normal karyotype (the Norm-group). The other 113 pregnancies ended in miscarriage, and we categorized them into groups based on fetal karyotype, determined by chorionic villus sampling: the Misc-NK (normal karyotype) group, n=35 euploid cases; the Misc-CA1 (chromosomal abnormality) group, n=18 cases of aneuploidy with trisomies 13/18/21, Turner's syndrome, or Klinefelter's syndrome; and the Misc-CA2 subgroup, n=60 cases of other aneuploidies excluding those in the Misc-CA1 group...

INTRODUCTION: The aim of this study was to characterize lesion distribution in Parsonage-Turner Syndrome (PTS) using high-resolution MRI. METHODS: The MRIs of 27 patients with clinically confirmed PTS were reviewed. Two radiologists independently evaluated the brachial plexus proper, side and terminal plexus branches, and more distal, upper extremity nerves. RESULTS: All patients had at least 1 clinically involved nerve. On MRI, the plexus appeared normal in 24/27 patients; in 3 others, signal hyperintensity was seen immediately proximal to the take-off of abnormal side or terminal branch nerves...

BACKGROUND: The usage of Artificial Neural Networks (ANNs) for genome-enabled classifications and establishing genome-phenotype correlations have been investigated more extensively over the past few years. The reason for this is that ANNs are good approximates of complex functions, so classification can be performed without the need for explicitly defined input-output model. This engineering tool can be applied for optimization of existing methods for disease/syndrome classification. Cytogenetic and molecular analyses are the most frequent tests used in prenatal diagnostic for the early detection of Turner, Klinefelter, Patau, Edwards and Down syndrome...

Context: Most girls with Turner Syndrome have hypergonadotropic hypogonadism and need hormonal replacement - for induction of puberty and later maintaining secondary sex characteristics, attaining peak bone mass, and uterine growth. The optimal estrogen replacement regimen is still being studied. Evidence Acquisition: We conducted a systematic search of PubMed for research related to TS and puberty, including key words: estrogen, growth, puberty. Evidence Synthesis: The goals of replacement are to mimic normal timing and progression of physical and social development while minimizing risks...
