Major obstetric hemorrhage is the leading cause of maternal morbidity and mortality. In rare cases, life-threatening hemorrhage in pregnant women may result from abnormal adherence of placenta. Three grades of abnormal placental attachment are defined according to the depth of invasion: placenta accreta, placenta increta, and placenta percreta. An important risk factor for placenta abnormal adherence of placenta is placenta previa in the presence of a uterine scar. The increased prevalence of cesarean section, uterine surgery, and increasing parturient age and parity have led to an increased incidence of abnormal placentation, from one in 2,500 a quarter century ago, to one in 533 deliveries currently...

Congenital and perinatal primary brain neoplasms are extremely rare. Brainstem neoplasms in the perinatal and neonatal period are typically of high-grade nature and have poor prognoses with survival rates of less than 2 years from diagnosis. Herein, we report an unusual case of congenital anaplastic oligodendroglioma that arose in the pons and was detected as diffuse pontine glioma on in utero imaging studies during prenatal evaluation at 26 weeks' gestation. A male infant was delivered at 36.4 weeks of gestation via Cesarean section who developed progressive dyspnea shortly after birth...

Congenital cystic lung lesions are a group of rare pathologies that are usually diagnosed in the prenatal period. The majority of these lesions are diagnosed at pathology examination as congenital pulmonary airway malformations (CPAM) and bronchopulmonary sequestration (BPS). These lesions are typically managed by surgical intervention within the first year of life and have an excellent prognosis. We examined the evolution of imaging appearances from prenatal diagnosis to postnatal work-up of these lesions and correlate imaging and pathological findings...

The mechanisms of vascular alterations resulting from early thyroid hormones deficiency are poorly understood. We tested the hypothesis that antenatal/early postnatal hypothyroidism would alter the activity of endothelial NO-pathway and Rho-kinase pathway, which are specific for developing vasculature. Dams were treated with propylthiouracil (PTU, 7 ppm) in drinking water during gestation and 2 weeks after delivery, their progeny had normal body weight but markedly reduced blood levels of thyroid hormones (ELISA)...

Hypoxic-ischaemic episodes experienced at the perinatal period commonly lead to a development of neurological disabilities and cognitive impairments in neonates or later in childhood. Clinical symptoms often are associated with the observed alterations in white matter in the brains of diseased children, suggesting contribution of triggered oligodendrocyte/myelin pathology to the resulting disorders. To date, the processes initiated by perinatal asphyxia remain unclear, hampering the ability to develop preventions...

Perinatal hypoxic-ischemic reperfusion (I/R)-related brain injury is a leading cause of neurologic morbidity and life-long disability in children. Infants exposed to I/R brain injury develop long-term cognitive and behavioral deficits, placing a large burden on parents and society. Therapeutic strategies are currently not available for infants with I/R brain damage, except for hypothermia, which can only be used in full term infants with hypoxic-ischemic encephalopathy (HIE). Moreover, hypothermia is only partially protective...

Group B streptococci (Streptococcus agalactiae) cause a number of infections in women during pregnancy and postpartum, such as urinary tract infection, chorioamnionitis and endometritis, consequently may affect the newborn. Group B streptococci is the most common cause of severe infections in newborns in developed countries. Studies on the epidemiology of group B streptococci infections in Latin America are still limited. This information is also unknown in Mexico, but studies carried out in the center of the country have found high rates of vaginal colonization in pregnant women and there are case series and case reports of newborns...

Neonatal hypoxia ischemia (HI) plays a role in the etiology of several neurological pathologies and causes severe sequelae. Acetylcholine is a neurotransmitter in the central nervous system and cholinesterase inhibitors have demonstrated a positive action over HI induced deficits. In order to evaluate the effects of pre and post-hypoxia administrations of galantamine, a cholinesterase inhibitor, in a model of perinatal HI, Wistar rats in the post-natal day 7 (PND7) were subjected to a combination of unilateral occlusion of the right carotid artery with the exposure to a 1h hypoxia...

BACKGROUND: Although HIV infection is associated with well-known oral pathologies, there remains a dearth of comparative studies aimed at determining the association between HIV infection/exposure and early childhood caries. METHODS: This is a cross-sectional study using a convenience sample of 3 groups of children receiving care at a tertiary care hospital in Nigeria. The groups include HIV infected (HI); HIV exposed but uninfected (HEU); and HIV unexposed and uninfected (HUU) children aged 6 through 72 months...

A balanced interaction between the homeostatic mechanisms of mother and the developing organism during pregnancy and in early neonatal life is essential in order to ensure optimal fetal development, ability to respond to various external and internal challenges, protection from adverse programming, and safeguard maternal care availability after parturition. In the majority of pregnancies, this relationship is highly effective resulting in successful outcomes. However, in a number of pathological settings, perturbations of the maternal homeostasis disrupt this symbiosis and initiate adaptive responses with unpredictable outcomes for the fetus or even the neonate...

Neuroectodermal developmental anomalies are reported rarely in cetaceans and central nervous system cysts are not described. We describe the gross, microscopical, histochemical and immunohistochemical features of a neuraxial myelencephalic cyst in a stranded neonatal Burmeister's porpoise (Phocoena spinipinnis). Grossly, a subdural, extra-axial, well-demarcated, yellow fluid-filled cystic structure (1.9 × 1.6 × 1 cm) expanded the left foramen of Luschka, the left caudolateral cerebellar recess and the left cranioventral myelencephalon...

Conditions causing reproductive failure are a significant concern in the livestock industry, and amongst these, ovine toxoplasmosis is one of the most important. Despite decades of research, there remain gaps in knowledge about this disease, especially regarding the pathogenesis of abortion in sheep. As for other diseases causing ovine abortion, such as chlamydial abortion or border disease, the consequences of infection with Toxoplasma gondii depend largely on the stage of gestation, but the mechanisms involved are not well understood...

Perinatal autopsy remains the gold-standard procedure used to establish the fetal, neonatal or infant abnormalities. Progressively, perinatal pathology has become a specialized field with important roles of audit for fetal prenatal diagnostic tools, in parents counseling regarding future pregnancies, in scientific research, for epidemiology of congenital abnormalities and teaching. The differences between prenatal ultrasound and autopsy reports represent a strong argument for the autopsy examination following termination of pregnancy...

Sudden perinatal death that includes the victims of sudden infant death syndrome, sudden intrauterine death syndrome, and stillbirth are heartbreaking events in the life of parents. Most of the studies about sudden perinatal death were reported from Italy, highlighting two main etiological factors: prone sleeping position and smoking. Other probable contributory factors are prematurity, male gender, lack of breastfeeding, respiratory tract infections, use of pacifiers, infant botulism, extensive use of pesticides and insecticides, etc...

Congenital diverticula of the left ventricle, very rare malformations, are determined by an abnormal embryonic development of the ventricular wall and can be isolated or associated to other cardiac anomalies. In most of the cases, these pathologies are not symptomatic and in some patients can be associated to ventricular arrhythmia, cardiac rupture with tamponade and sudden death. Authors are presenting the case of a sudden death in an 8-weeks-old newborn due to rupture of a cardiac congenital diverticulum of the left ventricle, discovered only at the moment of the autopsic examination...
