Current guidelines indicate that in patients with developmental disabilities or congenital anomalies, chromosomal microarray (CMA) is a first-tier diagnostic test. However, for patients with obvious chromosomal syndromes such as trisomy 13, 18, and 21, G-banded karyotyping is still recommended over CMA for establishing a diagnosis. In the case presented herein, a female neonate was suspected of having trisomy 18 based on pre- and postnatal evaluations. Karyotyping was requested but not performed due to insufficient cell growth; Interphase fluorescence in situ hybridization (i-FISH) found an extra copy of chromosome 18...

OBJECTIVES: The biochemical serum markers free β-human chorionic gonadotropin (hCGβ) and pregnancy associated plasma protein A (PAPP-A), used in screening for trisomy 21 (T21), trisomy 18 (T18), and trisomy 13 (T13) during the first trimester, can be measured on different laboratory instruments e.g. Kryptor (Brahms) and Cobas (Roche). We compared the performance of these two analytical instruments when used for first trimester combined testing. DESIGN AND METHODS: Serum samples from 944 singleton pregnant women attending for first trimester combined testing were routinely assayed for hCGβ and PAPP-A on Kryptor, and re-analyzed on Cobas...

BACKGROUND: Since its debut in 2011, cell-free fetal DNA (cffDNA) screening has undergone rapid expansion with respect to both utilization and coverage. However, conclusive data regarding the clinical validity and utility of this screening tool, both for the originally included common autosomal and sex-chromosomal aneuploidies as well as the more recently added chromosomal microdeletion syndromes, has lagged behind. Thus, there is a continued need to educate clinicians and patients about the current benefits and limitations of this screening tool to inform pre and post-test counseling, pre/perinatal decision making and medical risk assessment/management...

Cardiac intervention remains controversial in patients with trisomy 13 and 18 and little is known about factors that may affect outcomes. The goal of this study was to evaluate preoperative factors and surgical approach with respect to outcomes in these patients. Patients with congenital heart disease and trisomy 13 or 18 presenting to our institution from 2004 through 2015 were retrospectively reviewed. Patients were grouped into complete intervention, palliated intervention, and non-intervention. Pre-intervention variables, timing and type of intervention, post-intervention outcomes, and survival were recorded and comparisons were made between the groups...

A low number of antral follicles may result in the selection of suboptimal oocytes that are prone to meiotic errors. The aim of this case-control study was to evaluate women receiving IVF treatment with low oocyte yield (defined as three or fewer oocytes retrieved after ovarian stimulation) who are at an increased risk of a trisomic pregnancy. Data were obtained from Danish and Dutch medical registries between 1983 and 2011. Analyses were carried out in 105 cases and 442 controls matched by age and year of IVF treatment...

OBJECTIVE: To develop a Canadian consensus document on maternal screening for fetal aneuploidy (e.g., Down syndrome and trisomy 18) in singleton pregnancies. OPTIONS: Pregnancy screening for fetal aneuploidy started in the mid 1960s, using maternal age as the screening test. New developments in maternal serum and ultrasound screening have made it possible to offer all pregnant patients a non-invasive screening test to assess their risk of having a fetus with aneuploidy to determine whether invasive prenatal diagnostic testing is necessary...

Trisomy 13 is a chromosomal disorder that occurs in complete or partial mosaic forms. It is characterized by central apnea, mental retardation, seizure and congenital heart disease. The survival of the patients with trisomy 13 is the majority dying before one month. Trisomy 13 is the worst life prognosis among all trisomy syndromes. It is reported the cause of death is central apnea. Special needs patients with mental retardation are recognized to have poorer oral health condition. Oral health related quality of life reflects daily activity and well-being...

Trisomy 13 (T13) is accompanied by severe complications, and it can be challenging to achieve long-term survival without aggressive treatment. However, recently, some patients with T13 have been receiving home care. We conducted this study to investigate factors related to home health-care transition for patients with T13.We studied 28 patients with T13 born between January 2000 and December 2014. We retrospectively compared nine home care transition patients (the home care group) and 19 patients that died during hospitalization (the discharge at death group)...

BACKGROUND: Splenopancreatic fusion is a rare anomaly that is often associated with trisomy 13. Its diagnosis can be important in patients scheduled to undergo distal pancreatectomy or splenectomy, to avoid possible intraoperative or postoperative complications. CASE PRESENTATION: An 82-year-old Japanese man was referred to our hospital for further evaluation and treatment for a solitary hepatocellular carcinoma based on liver cirrhosis. Triple-phase contrast-enhanced multidetector-row computed tomography and magnetic resonance imaging showed a splenopancreatic fusion as well as a solitary hepatocellular carcinoma in segment VIII of his liver...

Trisomy 13 (Patau syndrome) is the third most common autosomal trisomy with a prevalence between 1 in 10,000 - 20,000 live births. Robertsonian translocations represent the largest number of chromosomal aberrations in human population with an incidence of 1.23 in 1000 live birth and translocation 13;14 is one of the most frequent Robertsonian translocations (approximately 75%). We sampled umbilical vein blood from a 27-yr-old woman whose ultrasonography findings revealed congenital heart defects, single ventricle, polycystic kidney, median cleft lip and palate and holoprosencephaly at gestational age of 23+6 weeks for karyotype and sequencing during intra-amniotic cavity injection of acrinol for labor induction...
