BACKGROUND: Radiotherapy may represent an alternative treatment modality for cystic echinococcosis (CE), but there is no adequate evidence for it up to now. In this study, we aim to investigate the parasiticidal effects of X-ray on the metacestodes of Echinococcus granulosus in vitro. METHODS: Protoscoleces obtained from sheep naturally infected with CE were cultivated in RPMI 1640 medium containing 10% fetal bovine serum (FBS) at 37 °C in 5% CO2. Upon encystation on day 14, the metacestodes were subjected to various intensities of X-ray...

Turner's syndrome (TS) is depicted as a total or partial absence of X chromosome, and occurs in approximately 1/2200 of live born females. Generally, mosaic patients are diagnosed following karyotype analysis due to recurrent pregnancy loss, repeated in vitro fertilization (IVF) failure, and a history of malformed babies. The purpose of this case report is to show that even a selection of normal karyotype embryos can result in abnormalities for those with mosaic TS. A 32-year old patient who underwent IVF after ICSI-PGD, and was diagnosed with 45X/46XX karyotype...

Hypoplastic left heart syndrome (HLHS) represents a variety of cardiac malformations that may result from errors in the early stages of cardiac development. HLHS includes a wide spectrum of cardiac malformations including hypoplasia of the left ventricle, ascending aorta, hypoplasia, or atresia of the aortic and mitral valves. Over the recent years, the improved resolution of advanced equipment with awareness and increased performance of second-trimester ultrasound examinations for the assessment of fetal anomalies have helped in understanding the spectrum and have expanded our knowledge of HLHS...

The caudal regression syndrome is defined as total or partial agenesis of the sacrum and lumbar spine, frequently associated with other developmental malformations (orthopedic, neurological, genito-urinary, gastrointestinal…). Prenatal diagnosis is possible through fetal ultrasound (US) and magnetic resonance imaging (MRI). A case of fetal caudal regression syndrome with omphalocele from a diabetic mother is presented, demonstrating the sonographic, MRI, CT and X-Ray features diagnostic. We will also discuss neonatal findings, risk factors and prognosis of this condition...

The placenta is a highly specialized organ that is formed during human gestation for conferring protection and generating an optimal microenvironment to maintain the equilibrium between immunological and biochemical factors for fetal development. Diverse pathogens, including viruses, can infect several cellular components of the placenta, such as trophoblasts, syncytiotrophoblasts and other hematopoietic cells. Viral infections during pregnancy have been associated with fetal malformation and pregnancy complications such as preterm labor...

BACKGROUND: The differential diagnosis for primary lung masses in neonates includes a variety of developmental abnormalities; it also consists of the much rarer congenital primary lung tumors: cystic pleuropulmonary blastoma (cystic PPB), fetal lung interstitial tumor (FLIT), congenital peribronchial myofibroblastic tumor (CPMT), and congenital fibrosarcoma. Radiologic differentiation between malformations and tumors is often very challenging. OBJECTIVE: The objective was to establish distinctive features between developmental pulmonary abnormalities and primary lung tumors...

During gestation, Toxoplasma gondii infection produces a series of complications including stillbirths, abortions, and congenital malformations. The inhibitory receptor, LILRB4, which is mainly expressed by professional antigen-presenting cells (especially macrophages and dendritic cells) may play an important immune-regulatory role at the maternal-fetal interface. To assess the role of LILRB4 during T. gondii infection, LILRB4(-/-) and T. gondii infected pregnant mouse models were established. Further, human primary-decidual macrophages were treated with anti-LILRB4 neutralizing antibody and then infected with T...

Although nanoscale titanium dioxide (nano-TiO2) has been extensively used in industrial food applications and daily products for pregnant women, infants, and children, its potential toxicity on fetal development has been rarely studied. The main objective of this investigation was to establish the effects of maternal exposure of nano-TiO2 on developing embryos. Female imprinting control region mice were orally administered nano-TiO2 from gestational day 0 to 17. Our findings showed that Ti concentrations in maternal serum, placenta, and fetus were increased in nano-TiO2-exposed mice when compared to controls, which resulted in reductions in the contents of calcium and zinc in maternal serum, placenta, and fetus, maternal weight gain, placental weight, fetal weight, number of live fetuses, and fetal crown-rump length as well as cauda length, and caused an increase in the number of both dead fetuses and resorptions...

Routine pregnancy ultrasound scans can detect malformations. Multidisciplinary care of both the foetus and parent is required following diagnosed malformations In Sweden, all women are invited to at least one ultrasound examination during pregnancy. The »Routine ultrasound screening« is usually performed by a midwife around 18 weeks of gestation. There are several aims of the examination: to check viability, to detect multiple fetuses, to determine the location of the placenta, to check the amount of amniotic fluid, to estimate the date of delivery (if this had not been done earlier) and to detect structural fetal malformations...

Prenatal first trimester fetal diagnosis in Sweden today and in the future The combined first trimester test for detection of trisomy 21 has been available in Sweden the last 10 years but the uptake among pregnant women is still less than 50% and varies largely between different regions. The non-invasive prenatal test (NIPT) has been introduced and is currently recommended to be used as a secondary test only in those women who have an increased risk following the combined test. With falling costs for NIPT and a general offer of this test as a primary screening tool to all women there is concern that the first trimester ultrasound scan will be abandoned...

Congenital heart defects are structural cardiovascular malformations that arise from abnormal formation of the heart or major blood vessels during the fetal period. To investigate the association of 4 single nucleotide polymorphisms (SNPs) in the MTHFD1, eNOS, CBS and ACE genes, we evaluated their relationship with CHD in Iranian patients. In this case-control study, a total of 102 children with CHD and 98 control children were enrolled. Four SNPs including MTHFD1 G1958A, eNOS G894T, CBS C-4673G and ACE A2350G were genotyped by PCR-SSCP, Multiplex ARMS PCR and PCR-RFLP methods and confirmed by direct sequencing...
