Pericardial effusion (PE) may require readmission after cardiac surgery and has been associated with postoperative morbidity and mortality. We sought to identify the prevalence and risk factors for postoperative PE requiring readmission in children. A retrospective analysis of the Pediatric Health Information System database was performed between January 1, 2003, and September 30, 2014. All patients ≤18 years old who underwent cardiac surgery were identified by ICD-9 codes. Those readmitted within 1 year with an ICD-9 code for PE were identified...

Objective To determine patient perception of residual risk after receiving a negative non-invasive prenatal testing result. Introduction Recent technological advances have yielded a new method of prenatal screening, non-invasive prenatal testing (NIPT), which uses cell-free fetal DNA from the mother's blood to assess for aneuploidy. NIPT has much higher detection rates and positive predictive values than previous methods however, NIPT is not diagnostic. Past studies have demonstrated that patients may underestimate the limitations of prenatal screening; however, patient perception of NIPT has not yet been assessed...

A new human uterine carcinosarcoma (UCS) cell line, TU-ECS-1, was established and characterized. The morphological appearance of the cultured cells was an insular of epithelial-like cells arranged in the form of a jigsaw puzzle and mesenchymal-like cells with a spindle-shaped or fibroblast-like morphology. A relatively high proliferation rate was observed with a doubling time of 18.2 h. The chromosome number ranged from 44 to 49 and had an extra chromosome 12 (trisomy 12). The respective half-maximal inhibitory concentrations of cisplatin, paclitaxel, and doxorubicin were 2...

BACKGROUND: High hyperdiploid (HeH) pre-B pediatric acute lymphoblastic leukemia (B-pALL) is known to be heterogeneous by prognosis, but the stratification principals according to conventional cytogenetic analysis (CCA) are equivocal. PROCEDURE: Untreated bone marrow samples of 214 B-pALL patients were previously classified according to the modal numbers (iMN8) based on the gains of the chromosomes 4, 6, 10, 14, 17, 18, 21, and X as revealed by consecutive and correlated 2×4 color interphase fluorescence in situ hybridization, and at least five years of follow up data were analyzed...

REVIEW

Embryonic mosaicism occurs when two or more cell populations with different genotypes are present within the same embryo. New diagnostic techniques for preimplantation genetic screening (PGS), such as next-generation sequencing, have led to increased reporting of mosaicism. The interpretation of mosaicism is complicated because the transfer of some mosaic embryos has resulted in live births. Mosaic embryos may represent a third category between normal (euploidy) and abnormal (aneuploidy). This category of mosaic embryos may be characterized by decreased implantation and pregnancy potential as well as increased risk of genetic abnormalities and adverse pregnancy outcomes...

Infants with anotia and microtia (AM) often have other non-AM associated congenital anomalies. The purpose of this investigation was to assess the prevalence and the types of these associated anomalies in a defined population. The associated anomalies in infants with AM were collected in all livebirths, stillbirths and terminations of pregnancy during 29 years in 387,067 consecutive births in the area covered by our population-based registry of congenital malformations. Of the 146 cases with AM registered during this period, representing a prevalence of 3...

BACKGROUND: We hypothesized that fetal aortic mechanical properties assessed by aortic diameter (AoD) and flow show maturational changes during the gestational period, and that these properties are different in fetuses with congenital heart diseases and fetuses with normal development. METHODS: Phasic changes in ascending AoD along with Doppler flow profile were measured in 84 consecutive normal fetuses (gestational age, 18-36 weeks) and in 30 consecutive fetuses with cardiovascular diseases (gestational age, 22-39 weeks)...
