Environmental toxicants and fetal developmentEnvironmental toxicants and fetal development is the impact of different toxic substances from the environment on the development of the fetus. This article deals with potential adverse effects of environmental toxicants on the prenatal development of both the embryo or fetus, as well as pregnancy complications. The human embryo or fetus is relatively susceptible to impact from adverse conditions within the mother's environment. Substandard fetal conditions often cause various degrees of developmental delays, both physical and mental, for the growing baby.
Breast cancer classificationBreast cancer classification divides breast cancer into categories according to different schemes criteria and serving a different purpose. The major categories are the histopathological type, the grade of the tumor, the stage of the tumor, and the expression of proteins and genes. As knowledge of cancer cell biology develops these classifications are updated. The purpose of classification is to select the best treatment. The effectiveness of a specific treatment is demonstrated for a specific breast cancer (usually by randomized, controlled trials).
Neonatal lupus erythematosusNeonatal lupus erythematosus is an autoimmune disease in an infant born to a mother with anti-Ro/SSA and with or without anti-La/SSB antibodies. The disease most commonly presents with a rash resembling subacute cutaneous lupus erythematosus and can have systemic abnormalities such as complete heart block or hepatosplenomegaly. Neonatal lupus is usually benign and self-limited. Many of the clinical manifestations are transient, but certain heart problems can be permanent. Diagnosis is based on maternal antibodies and clinical manifestations.
Neonatal intensive care unitA neonatal intensive care unit (NICU), also known as an intensive care nursery (ICN), is an intensive care unit (ICU) specializing in the care of ill or premature newborn infants. The NICU is divided into several areas, including a critical care area for babies who require close monitoring and intervention, an intermediate care area for infants who are stable but still require specialized care, and a step down unit where babies who are ready to leave the hospital can receive additional care before being discharged.
Abdominal pregnancyAn abdominal pregnancy is a rare type of ectopic pregnancy where the embryo or fetus is growing and developing outside the womb in the abdomen, but not in the Fallopian tube (usual location), ovary or broad ligament. Because tubal, ovarian and broad ligament pregnancies are as difficult to diagnose and treat as abdominal pregnancies, their exclusion from the most common definition of abdominal pregnancy has been debated. Others—in the minority—are of the view that abdominal pregnancy should be defined by a placenta implanted into the peritoneum.
Inflammatory breast cancerInflammatory breast cancer (IBC) is one of the most aggressive types of breast cancer. It can occur in women of any age (and, extremely rarely, in men, see male breast cancer). It is referred to as "inflammatory" due to its frequent presentation with symptoms resembling a skin inflammation, such as erysipelas. Inflammatory breast cancer presents with variable signs and symptoms, frequently without detectable lumps or tumors; it therefore is often not detected by mammography or ultrasound.
Small for gestational ageSmall for gestational age (SGA) newborns are those who are smaller in size than normal for the gestational age. SGA is most commonly defined as a weight below the 10th percentile for the gestational age. SGA predicts susceptibility to hypoglycemia, hypothermia, and polycythemia. By definition, at least 10% of all newborns will be labeled SGA. All SGA babies should be watched for signs of failure to thrive, hypoglycemia and other health conditions.
Rupture prématurée des membranesLa rupture prématurée des membranes (la RPM) est l'ouverture de l'œuf avant le début de l'accouchement appelé « travail ». La rupture prématurée des membranes avant le terme de huit mois est la première cause d'accouchement prématuré. Une cause n'est identifiée que dans 40 % des cas. Traumatisme direct ou indirect (coup porté au niveau abdominal, accident de circulation, rapports sexuels) Cause obstétricale : grossesse gémellaire, hydramnios Iatrogène : complication d'une amnioscopie, de la pose d'un laminaire au cours d'une interruption volontaire de grossesse (IVG).
Échographie obstétricalevignette|Mouvements d'un bébé à 12 semaines. Cet article fournit diverses informations concernant les échographies lors de la grossesse. L'échographie obstétricale est réalisée par voie abdominale ou endovaginale selon les indications. En France, la Sécurité sociale admet le remboursement de 3 échographies au cours de la grossesse : autour des , et d'aménorrhée (date des dernières règles). Ces dates correspondent aux moments les meilleurs pour faire le dépistage des anomalies morphologiques pouvant exister.
Cancer de l'ovaireLe est une forme de cancer affectant un ovaire. Il se développe généralement à partir du revêtement de surface des ovaires. La forme la plus fréquente est le carcinome épithélial de l'ovaire. Les formes rares, comme les tumeurs germinales de l'ovaire ou les tumeurs borderline , justifient d'une prise en charge spécifique. Le cancer de l'ovaire est en général de mauvais pronostic car découvert souvent tardivement. L'ovaire est situé dans le petit bassin et une lésion tumorale peut se développer lentement sans signes cliniques.
Neonatal jaundiceNeonatal jaundice is a yellowish discoloration of the white part of the eyes and skin in a newborn baby due to high bilirubin levels. Other symptoms may include excess sleepiness or poor feeding. Complications may include seizures, cerebral palsy, or kernicterus. In most of cases there is no specific underlying physiologic disorder. In other cases it results from red blood cell breakdown, liver disease, infection, hypothyroidism, or metabolic disorders (pathologic). A bilirubin level more than 34 μmol/L (2 mg/dL) may be visible.
Diagnostic prénatalLe diagnostic prénatal (DPN) ou diagnostic anténatal (DAN) est l'ensemble des pratiques médicales ayant pour but de détecter in utero chez l'embryon ou le fœtus une affection grave (anomalie génétique ou malformation congénitale, par exemple), afin de donner aux futurs parents le choix d'interrompre ou non la grossesse et de permettre une meilleure prise en charge médicale de la pathologie si la grossesse est poursuivie.
