BACKGROUND: There has been a recent increase in the number of newborns with brain malformations due to congenital infections, but the impact of these diseases remains largely under ascertained in middle-income and low-income countries. This case report presents a fetal anencephaly following maternal toxoplasma and rubella co-infection in a resource-limited setting and the challenges faced by the patient and the health care provider in the management of the condition. CASE PRESENTATION: A 25-year-old black Cameroonian woman of Bakossi origin, gravida3 para1010, presented with a positive rubella and toxoplasma immunoglobulin G serologic test at 21 weeks of pregnancy; she could not benefit from a fetal morphologic ultrasound partly because there was none at the site of her antenatal clinic and because there were accessibility constraints getting to the nearest referral hospital approximately 100 km away...

The structural integrity of the cervix in pregnancy is necessary for carrying a pregnancy until term, and the organization of human cervical tissue collagen likely plays an important role in the tissue's structural function. Collagen fibers in the cervical extracellular matrix exhibit preferential directionality, and this collagen network ultrastructure is hypothesized to reorient and remodel during cervical softening and dilation at time of parturition. Within the cervix, the upper half is substantially loaded during pregnancy and is where the premature funneling starts to happen...

INTRODUCTION: Up to 50% of the infants delivered after radical vaginal trachelectomy (RVT) are born prematurely. An effective strategy to reduce this number could be the closure of the cervical os (CCO). PATIENTS AND METHODS: Fifteen pregnant patients who had a RVT due to early cervical cancer were included in this prospective case control study. All patients were scheduled for CCO early in the second trimester. CCO was performed in 12 patients. Their data were compared to data from 125 pregnancies after a RVT without CCO...

BACKGROUND: -The natural history of aortic diseases in patients with TGFBR1 or TGFBR2 mutations reported by different investigators has varied greatly. In particular, the current recommendations for the timing of surgical repair of the aortic root aneurysms may be overly aggressive. METHODS AND RESULTS: -The Montalcino Aortic Consortium, which includes 15 centers worldwide that specialize in heritable thoracic aortic diseases, was used to gather data on 441 patients from 228 families, with 176 cases harboring a mutation in TGBR1 and 265 in TGFBR2 Patients harboring a TGFBR1 mutation have similar survival rates (80% survival at 60 years), aortic risk (23% aortic dissection, 18% preventive aortic surgery), and prevalence of extra-aortic features (29% hypertelorism, 53% cervical arterial tortuosity, 27% wide scars) when compared to patients harboring a TGFBR2 mutation...

BACKGROUND: Clinically, once a woman has been identified as being at risk of spontaneous preterm birth (sPTB) due to a short cervical length, a decision regarding prophylactic treatment must be made. Three interventions have the potential to improve outcomes: cervical cerclage (stitch), vaginal progesterone and cervical pessary. Each has been shown to have similar benefit in reduction of sPTB, but there have been no randomised control trials (RCTs) to compare them. METHODS: This open label multi-centre UK RCT trial, will evaluate whether the three interventions are equally efficacious to prevent premature birth in women who develop a short cervix (<25 mm on transvaginal ultrasound)...

BACKGROUND: Intra-uterine pregnancy coexisting with cervical pregnancy (heterotopic pregnancy) is a rare condition and its management is challenging because of the massive bleeding associated with cervical pregnancy. Uterine artery embolization followed by hysteroscopic removal of cervical and intra-uterine products of conception can theoretically prevent massive bleeding and provide a direct view during the removal. Hysteroscopic management following uterine artery embolization of heterotopic pregnancy after in vitro fertilization and embryo transfer is rarely reported...

The cervical mucus plug (CMP) is believed to play an integral role in the maintenance of pregnancy in the mare, primarily by inhibiting microbial entry. Unfortunately, very little is known about its composition or origin. To determine the proteomic composition of the CMP, we collected CMPs from mares (n = 4) at 9 months of gestation, and proteins were subsequently analyzed by nano-LC-MS/MS. Results were searched against EquCab2.0, and proteomic pathways were predicted by Ingenuity Pathway Analysis. Histologic sections of the CMP were stained with H&E and PAS...

Pregnancy-associated cancer constitutes an uncommon and difficult to manage clinical situation. It is defined as the cancer diagnosed from the first day of childbearing to 1 year post partum. Coexistence of cancer with pregnancy adds complexity to treatment recommendations, as both the mother and the fetus may be affected. The optimal therapeutic management of pregnant women with cancer diagnosis should take into account, apart from medical factors, a host of other parameters (ethical, psychological, religious, legal, etc)...

Preterm birth (PTB), defined as delivery at <37 weeks of gestation, is the most important cause of neonatal morbidity and mortality. Therefore, preventing PTB is one of the main goals in obstetric care. In this review, we provide an overview of the current available literature on screening for risk factors for PTB and a summary of preventive strategies in both low-risk and high-risk women with singleton or multiple gestations. Furthermore, current challenges and future prospects on PTB are discussed. For an optimal prevention of PTB, risk stratification should be based on a combination of (maternal) risk factors, obstetric history, and screening tools...
