Cocaine as a Teratogen Cocaine use by pregnant women has a variety of effects on the embryo and fetus, ranging from various gastro-intestinal and cardiac defects to tissue death from insufficient blood supply. Thus, cocaine has been termed a teratogen, or an agent that causes defects in fetuses during prenatal development. Cocaine is one of the most commonly used drugs in the US and it has a history of both medical and illegal recreational use. It is a drug capable of a wide array of effects on physical and mental health. Research on the teratogenic effects of cocaine began in the early 1980s, and in 1985 research on the effects of cocaine on prenatal development gained widespread attention.

Update on the Use of Antihypertensive Drugs in Pregnancy BP control is gradual, over 6 to 8 hours, because of the indirect mechanism of action. It is not thought to be teratogenic based on limited data and a 40-year history of use in pregnancy. Adverse effects are consequences of central α2-agonism or decreased peripheral sympathetic tone.

- The risk to the developing baby from seizure medications taken during pregnancy is primarily that of congenital malformation or birth defects. In the general population, there is a 2% to 3% occurrence of congenital malformations that cannot always be predicted or prevented.

Common Teratogens and Their Effects the study of abnormal development in embryos and the causes of congenital malformations or birth defects. Effects of teratogens on the fetus. Factors that influence the amount of damage a teratogen can cause: l Strength of teratogens (ex: radiation) l Timing of the teratogenic insult l Determining the effects of a teratogen.

- The European medieval diet was largely determined by social class. For the majority of the of the people, peasants, a large portion of their daily diet was made up of grains such as wheat, rye, oats or barley(carbohydrates).The grains were boiled whole in a soup or stew, ground into flour and made into bread, or malted and brewed into ale. prosperous English peasant in the 14th century would probably consume 2 - 3 pounds of bread, 8 ounces of meat or fish or other protein and 2 -3 pints of ale per day. The bread was usually mean of rye, oats, or barley.

Teratogens - Risky Pregnancy Exposures Like Drinking and Smoking Alcohol is one of the most concerning teratogens. It quickly passes from your blood to your baby's blood through the placenta and umbilical cord. Your fetus has the same blood alcohol level that you do if you drink, but it doesn't have the same ability to break down the alcohol.

Mirtazapine (Remeron) Untreated MDD has risks to the fetus, as well as the mother. It is important to discuss the risks and benefits of treatment with your doctor and caregivers. Caution is advised with breastfeeding since mirtazapine does pass into breast milk.

Things to Avoid During Pregnancy: Teratogens 1 ACE inhibitors can cause fetal growth restriction, problems with the baby’s kidneys, and sometimes death of the baby during pregnancy. 2  Isotretinoin, which is used to treat severe acne, is also linked with a number of congenital abnormalities.

Hida Scan and Breastfeeding Choletec (BrIDA, MEB, Mebrofenin) is a carrier for the radioactive Tc-99m that makes it go straight to the organ of interest. The Choletec conjugate is not dangerous by itself; only the Tc-99m matters in terms of breastfeeding safety. The radioactive half-life of Tc-99m is fixed at 6 hours and is entirely independent of any influence by Choletec. The International Commission on Radiological Protection (ICRP) and the American Academy of Pediatrics do not specifically mention Choletec in their breastfeeding safety recommendations for Tc-99m.

- Certain medications such as heparin cannot cross the placenta due to its high molecular. weight and are therefore not teratogenic. The embryo is most susceptible to teratogenic agents. during periods of rapid differentiation. The stage of development of the embryo determines suscep-. tibility to teratogens. The most critical period in the development of an embryo or in the growth of a. particular organ is during the time of most rapid cell division. The critical period for each organ is. pictured below (Fig. 23-2).

Weather The Grand Canyon itself influences weather. Tremendous changes in elevation cause large gradients in temperature and precipitation. The coolest, wettest weather station in the region (Bright Angel Ranger Station on the North Rim) is less than eight miles from the hottest and one of the driest stations (Phantom Ranch). The coldest temperature recorded was –22 °F on the North Rim on February 1, 1985.

Annals of Clinical & Laboratory Science Because the fetus is less susceptible to morphologic alterations when the developmental process of the majority of organs has been completed, the most common anomalies associated with teratogenic exposures during the fetal period are fetal growth restriction (intrauterine growth retardation) and mild errors of morphogenesis (abnormalities of phenogenesis), such as epicanthic folds, clinodactyly, and others.

Teratogens - Risky Pregnancy Exposures Like Drinking and Smoking A teratogen is any agent that causes abnormalities when a developing baby is exposed to it during the mother's pregnancy. These environmental exposures can cause birth defects and other problems. 1  Teratogens are can have effects that range from mild to severe, and they are often most dangerous during early pregnancy and with excessive or prolonged exposure. There are several factors that influence the severity of the effect:

8 Principles of Teratogens Effects of teratogen on critical period. The organism is most vulnerable to teratogens during the embryonic period. - ex: the most vulnerable period for the heart is between 20 and 40 days after conception. Each teratogen exerts specific effects. Different teratogens influence different developmental processes. - ex: Rubella or German measles in mother affect mainly the fetus's heart, brain, and eyes.
