Teratogens

The timing of prenatal exposure to the teratogen, the dosage of the teratogen, and the individual differences in sensitivity to a particular teratogen. Alcohol is one of the most common and preventable causes of birth abnormalities. The amount of alcohol consumed during pregnancy, the timing of drinking, and individual differences in sensitivity to alcohol all play a role of the extent and nature of effects caused by prenatal exposure to alcohol. A child whose mother drank during pregnancy is likely to have Fetal Alcohol Spectrum Disorders. Children with FASD are likely to have behavioral problems and lower IQs, which results in them struggling in school and contribute to poor social skills. Drinking during pregnancy can also compromise physical

The quality of life for these children is unfortunately not the best. They can have limb, facial, and organ defects, and will have stunted physical growth throughout young adult life. Prenatal exposure can also have a negative effect on motor skills, especially fine motor tasks such as writing and balancing. The disabilities depend on the mother and her drinking habits. The children of heavy drinkers while pregnant, have many more developmental problems than of those whose mother was a light drinker. The most common problems among these children with alcohol exposure are with balance, coordination, and how they are able to play and handle a ball.

According to the Centers for Disease Control and Prevention (CDC), birth defects results in one of every 33 babies. Teratogens account for 4 out of 5% of birth defects when chemical and drugs are in the system. The use of this or even infections can cause abnormal fetal development.

Fetal alcohol spectrum disorder (FASD) is a general term consist disabilities when a mother consumes alcohol during her pregnancy. The medical prognosis of FASD includes: Fetal Alcohol Syndrome (FAS), Partial Fetal Alcohol Syndrome (PFAS), Alcohol Related Neurodevelopmental Disorder (ARND) and Alcohol Related Birth Defects (ARBD). Moreover, teratogen is a harmful agent that can interrupt the development of an embryo. For instance, alcohol is teratogen. As per Health Canada, FASD is a leading cause of a completely avertable developmental disability but it still affects approximately one percent of the Canadian population (Batshaw, Roizen & Lotrecchiano, 2012). However, there are many alterations to the disabilities and the development of sub-groups. Thereby, the term FASD is introduced to ensure the incidence of all the characteristics (mental, behavioral and physical) associated with prenatal exposure to alcohol. The exposure to alcohol during the pregnancy places the infant at the risk of developing problems such as abnormal appearance, low body weight, poor coordination, low intelligence, facial abnormalities, neuropsychological deficits, central nervous system deficits and growth delays (Riley, Infante & Warren, 2011). As the paper progress, we will discuss the characteristics, causes and the epidemiology of FASD. In addition we will all focus on the mental disorder such as Attention Deficit Hyperactivity Disorder (ADHD) associated with FASD and a

In 1996, the United States Institue of Medicine published Fetal Alcohol Syndrome: Diagnosis, Epidemiology, Prevention and Treatment. The book created four diagnostic categories for disorders caused by prenatal alcohol exposure. They were: Fetal Alcohol Syndrome (FAS), Partial Fetal Alcohol Syndrome (PFAS), Alcohol Related Birth Defects (ARBD) and Alcohol Related Neurodevelopmental Disorders (ARND)(Stratton,1996). The differences between the disorders include the types of defects expressed and whether or not maternal alcohol consumption is confirmed. For example, ARND is characterized by intellectual disabilities and behavior and learning problems in the absence of physical defects. ARBD, on the other hand, lacks apparent neurobehavioral or brain disorders, but physical defects linked to prenatal alcohol exposure are present. (NOFAS)

Alcohol is known as one the most dangerous teratogens. Every time a pregnant woman drinks, she allows alcohol to enter her blood stream and make its way into the placenta. Unlike the mother, the fetus is unable to break down alcohol that makes the blood alcohol level of the fetus the same or higher than the mother (Burk, 2013). Fetal alcohol syndrome (FAS), and prenatal alcohol exposure (PAE) are considered some of the most serious consequences of maternal drinking during pregnancy. Children can exhibit physical abnormalities such as a flat mid-face, a thin upper lip, a smooth groove between the nose and upper lip, along with growth retardation, and cognitive difficulties. The affected children also have cognitive difficulties which include intelligence, language, memory, and learning (Wacha & Obrzut, 2007).

Alcohol, even at small portions, have a great effect on an infant. Toddlers become uncontrollable and hostile towards parents due to the consumption of liquor. In particular, mothers who drank while pregnant have increased the risk of having a daughter who has a mental illness. Drinking during pregnancy causes impairment to vital organs and causes permanent health problems to the soon to be born

When the fetus is exposed to the teratogens during the prenatal stage, then, in that case, there are significantly high chances that the child will suffer from birth defects (4). There are different factors which are related to the level of exposures to the teratogens; amount of damage that a particular teratogen can have along with the level of dosages, heredity, age of the teratogen and the different other negative influences like that of the combination of teratogens with poor health etc. (1). There are different types of teratogens which pregnant women are advised to avoid like alcohol, prescription drugs/illegal drugs and tobacco. Alcohol use is one of the most use and major problem throughout pregnancy (4). Although it hasn’t been determined how much alcohol is detrimental to pregnant women, it has been found to be one of the major cause of mental disabilities in children in the United States (4). Alcohol usually passes from the mother’s blood stream via the placenta to the fetus. Indeed, maternal drinking is tied to fetal alcohol spectrum disorders (FASD) with life-long consequences for the new born (1). The research suggests that alcohol exposure to the 19th or 20th of gestation can significantly exposed the new born to facial abnormalities (1). It is unknown how much alcohol is necessary to cause damage, so doctors typically recommend that alcohol should be completely avoided during

A teratogen is a substance that acts as a toxin that can cause a birth defect. A teratogen can be a prescribed medication, a street drug, alcohol use, or even a disease present in the mother that can cause an increased risk for the baby to be born with a birth defect. Some teratogens may cause birth defects that are noticed immediately at birth and some you can’t determine for several years. Usually the more and longer the developing fetus is exposed to teratogens the worse the consequences will be.

Even a small amount of alcohol has the potential to hurt the child. The unborn child of a person who occasionally drinks is at risk of receiving fetal alcohol effects. This condition causes children to receive some of the same of the same effects that come from fetal alcohol syndrome. A child may not receive any of these conditions due to a mother’s alcohol consumption, but there are still some potential effects. Evidence shows that when a pregnant mother consumes an average of two alcoholic beverages per day, her child may have a lower amount of intelligence and is also at risk for having mental retardation. Also, there is research that suggests that even low quantities of alcohol consumed during pregnancy can have contrary effects on the child’s behavioral and psychological functions, and can cause a child to exhibit behaviors such as hyperactivity, unusual nervousness or anxiety, and poor impulse control. Alcohol consumption during pregnancy can also cause children to have less accuracy in their spatial and visual reasoning later in their lives. Due to these results, Sarah should be advised to not drink alcohol while she is

Why it is important in our society to know what teratogen is, and some ways to prevent this birth defect in our society. Teratogen is a agent that disturbs the development of an embryo. Well, what exactly causes these disturbances in the embryo? By taking medicine during pregnancy, medicine prescribe to new mothers can cause abnormality in pregnancy. Although many women take medications during pregnancy, the medicine prescribe can be harmful. A example may be a woman during pregnancy comes across morning sickness; therefore, she may ask her doctor to prescribe medicine to treat her morning sickness. A common medicine to take during the 60's was thalidomide. However, over the years researchers found that thalidomide caused partial absence

Teratogens can harm an embryo. Most will not kill an embryo. However, any large quantity of teratogens like nicotine will

Repeated exposure to the chemical benzene can be a factor in AML development. Benzene damages the DNA of normal marrow cells. According to the Agency for Toxic Substances and Disease Registry, despite the fact that petroleum products contribute to the majority of benzene in the atmosphere, half of the total national personal exposure to benzene comes from cigarette smoke. Benzene is also found in certain industrial settings. Genetic disorders, such as Fanconi’s anemia, Shwachman syndrome, Diamond-Blackfan syndrome and Down syndrome, are associated with an increased risk of AML. Very rarely, an unexpectedly high number of cases of AML may be diagnosed within the same family. Clusters of AML in unrelated people within a community

Teratogen is the cause or increase the chance of a birth defect. Teratogen that pregnant women exposed are prescribed medication, chemical exposure or an infection present in a mother. I think those can cause an increase chance of the baby to be born with a defect. Nicotine does not produce congenital malformations. Maternal smoking is well –established cause of intrauterine growth restriction. The ionizing radiations can injure the developing embryo due to cell death or chromosome injury. The two effects that teratogens are Diseases (Maternal illness) and Environmental Toxins. benefits of a prenatal test are Identified whether your baby is more likely to have a certain conditions, but they usually can’t make a definitive diagnosis. Prenatal testing provides information about your prenatal testing provides information about your baby's health before he or she is born. Some routine tests during pregnancy also check on your health. Before he or she is born. Some routine tests during pregnancy also check on your health. I don’t think it’s a

Unfortunately, it's true. And the older you are, the greater the risk. The baby's body is alkaline and old, acid. The risk increases if there are familial cases and close exposure to carcinogens already
