Terminal chromosome 1q deletion is rarely reported but causes typical malformations that have been well described in childhood. Clinical features include facial dysmorphy, growth and/or psychomotor retardation, brain agenesis or hypoplasia of the corpus callosum, epilepsy and occasional urogenital or cardiac malformations. The diagnosis of this condition is usually made at birth. The rare cases of antenatal diagnosis were based on microcephaly and growth retardation. In the present case, the foetus presented with an hypoplasia of the corpus callosum, a dysmorphic profile and a single umbilical artery...

One of the most severe detrimental environmental factors acting during pregnancy is foetal smoke exposure. The aim of this study was to assess the effect of maternal, paternal and parental smoking during pregnancy on relative leg length in 7- to 10-year-old children. The research conducted in the years 2001-2002 included 978 term-born children, 348 boys and 630 girls, at the age of 7-10 years. Information concerning the birth weight of a child was obtained from the health records of the women. Information about the mother's and the father's smoking habits during pregnancy and about the mothers' education level was obtained from a questionnaire...

Previous studies have demonstrated the influence of changes in the age at which women give birth, and of developments in prenatal screening and diagnosis on the number of pregnancies diagnosed and terminated with chromosomal anomalies. However, we are unaware of any population studies examining pregnancy terminations after diagnosis of chromosomal anomalies that has included all aneuploidies and the influence of maternal factors. The aims of this study were to examine the association between results of prenatal tests and pregnancy termination, and the proportion of foetuses with and without chromosomal anomalies referred for invasive diagnostic tests over time...

BACKGROUND: Hypothesised associations between in utero exposure to selective serotonin reuptake inhibitors (SSRIs) and congenital anomalies, particularly congenital heart defects (CHD), remain controversial. We investigated the putative teratogenicity of SSRI prescription in the 91 days either side of first day of last menstrual period (LMP). METHODS AND FINDINGS: Three population-based EUROCAT congenital anomaly registries- Norway (2004-2010), Wales (2000-2010) and Funen, Denmark (2000-2010)-were linked to the electronic healthcare databases holding prospectively collected prescription information for all pregnancies in the timeframes available...

Term, live abdominal pregnancy secondary to rupture of a uterine rudimentary horn is a rare condition. Pregnancies conceived in the rudimentary horn of the uterus usually rupture during early gestation and present as a catastrophic event. However, rarely, after rupture of the uterine horn the foetus may continue to grow in the abdominal cavity and reach term gestation. A primigravida with a term pregnancy was referred to our centre for caesarean section with ultrasonography findings of transverse lie and placenta previa...

Issue: The estimation of foetal weight is an integral part of prenatal care and obstetric routine. In spite of its known susceptibility to errors in cases of underweight or overweight babies, important obstetric decisions depend on it. In the present contribution we have examined the accuracy and error distribution of 35 weight estimation formulae within the normal weight range of 2500-4000 g. The aim of the study was to identify the weight estimation formulae with the best possible correspondence to the requirements of clinical routine...

BACKGROUND: Rhesus (Rh) D antigen is the most important antigen in the Rh blood group system because of its strong immunogenicity. When RhD-negative individuals are exposed to RhD-positive blood, they may produce anti-D alloantibody, potentially resulting in delayed haemolytic transfusion reactions and Rh haemolytic disease of the foetus and newborn, which are difficult to treat. Inhibition of the binding of anti-D antibody with RhD antigens on the surface of red blood cells may effectively prevent immune haemolytic diseases...

BACKGROUND: Despite decades of studying, the mechanisms maintaining high diversity in the genes of the Major Histocompatibility Complex (MHC) are still puzzling scientists. In addition to pathogen recognition and other functions, MHC molecules may act prenatally in mate choice and in maternal-foetal interactions. These interactions are potential selective mechanisms that increase genetic diversity in the MHC. During pregnancy, immune response has a dual role: the foetus represents foreign tissue compared to mother, but histo-incompatibility is required for successful pregnancy...

GABAA receptor activation exerts trophic actions in immature neurons through depolarization of resting membrane potential. The switch to its classical hyperpolarizing role is developmentally regulated. Previous results suggest that a hormonally biased sex difference exists at the onset of the switch in hypothalamic neurons. The aim of this work was to evaluate sex differences in GABAA receptor function of hypothalamic neurons before brain masculinization by gonadal hormones. Hypothalamic cells were obtained from embryonic day 16 male and female rat foetuses, 2 days before the peak of testosterone production by the foetal testis, and grown in vitro for 9 days...

Muriel Robertson (1883-1973) was a pioneering protozoologist who made a staggering number of important contributions to the fields of parasitology, bacteriology and immunology during her career, which spanned nearly 60 years. These contributions were all the more remarkable given the scientific and social times in which she worked. While Muriel is perhaps best known for her work on the life cycle and transmission of the African trypanosome, Trypanosoma brucei, which she carried out in Uganda at the height of a major Sleeping Sickness epidemic, her work on the Clostridia during the First and Second World Wars made significant contributions to the understanding of anaerobes and to the development of anti-toxoid vaccines, and her work on the immunology of Trichomonas foetus infections in cattle, carried out in collaboration with the veterinarian W...

Delhi is the second largest city of the world both in terms of population and area, as well as being the capital of India. Every year, thousands of people from different states throng to the capital in search of a job in order to earn a living. When these people die and their bodies are found without any identifying documentation, it is very difficult for the police to establish their identities. These bodies are labelled as unidentified/unclaimed or unknown, and are sent for usually sent for medicolegal autopsy...

REVIEW
Henry Murray
Antenatal foetal heart rate assessment was introduced into clinical medicine before clear evidence of any benefits had been reported. Ad hoc definitions were used to define normal and abnormal recordings resulting in a high false-positive rate for foetal compromise. The understanding of the foetal states resulted in an improved physiologically based assessment of the antenatal tracings and allowed their classification as (i) reactive - 2 accelerations in 10 min within a recording period of 120 min, (ii) unreactive - no accelerations seen in 120 min of tracing and (iii) decelerative - the presence of repetitive decelerations on an otherwise unreactive trace...

A 6.5-year-old clinically healthy German Shepherd Dog with regular oestrous cycles of 6 months was presented for pregnancy diagnosis on day 38 after ovulation (p.ov.). Ultrasonography revealed three individual placental sites in progressed resorption and two vital adequately developed foetuses sharing a joint placenta. On days 41 and 48 p.ov., sonographic signs indicated normal development of both foetuses, but on day 52 p.ov., both foetuses were found to be dead. A caesarean section was performed the same day...

Preimplantation genetic diagnosis (PGD) was introduced as an alternative to prenatal diagnosis: embryos cultured in vitro were analysed for a monogenic disease and only disease-free embryos were transferred to the mother, to avoid the termination of pregnancy with an affected foetus. It soon transpired that human embryos show a great deal of acquired chromosomal abnormalities, thought to explain the low success rate of IVF - hence preimplantation genetic testing for aneuploidy (PGT-A) was developed to select euploid embryos for transfer...

OBJECTIVE: Bipolar disorder in pregnancy may be difficult to treat. The dilemma is whether the women should continue medication throughout pregnancy, and maybe accept a minor risk to harm their unborn child, or discontinue medication and increase the risk of recurrence, which can lead to maternal morbidity, thereby endangering themselves and their foetus. Design and methods In September 2016, three electronic search databases; PubMed, Scopus and PsycInfo, were used searching for clinical trials concerning this question...

Oral lichen planus (OLP) is a common chronic inflammatory disorder that manifests as papular, reticular, or erosive lesions. OLP seriously affects a patient's quality of life, as it is associated with symptoms such as pain and a burning sensation. It is also accompanied by a risk of carcinogenic tendency. During pregnancy, the treatment will be more complicated because of the effect of medical treatment on both the mother and foetus. Thus, appropriate drugs for those pregnant patients will be more essential...

AIM OF THE STUDY: Pulmonary hypertension (PH) remains a therapeutical challenge in neonates born with congenital diaphragmatic hernia (CDH). Endoglin (Eng), an auxiliary receptor component of the transforming growth factor β (TGFβ) signalling pathway, is expressed mainly by endothelial cells and has been found to be involved in angiogenesis and vascular remodelling. Genetic studies have linked TGFβ and Eng mutations to human arterial PH and other cardiovascular syndromes. Eng interacts with the TGFβ receptors 1 and 2 (Tgfβr1, Tgfβr2)...
