Teratogenic diseases examples

Infective diseases during pregnancy and their teratogenic effects TORCH group infections (toxoplasmosis, others, rubella, cytomegalovirus, herpes) are the most serious infectious diseases during pregnancy due to the seriousness of possible embryo-fetal lesions 1 Some Examples Of Teratogens. 1.1 Thalidomide; 1.2 Accutane (Isotretinoin) 1.3 Diethylstilbestrol (DES) 1.4 Alcohol-Foetal Alcohol Syndrome; 1.5 Infectious Agents 2 Testing Protocols Of Teratogens; 3 Single-Generation Studies: Single-generation studies are short-term studies conducted in three segments. 3.1 Relate

Fetal alcohol syndrome can often be recognised at birth although it is more easily recognisable in childhood. It is a typical example of a congenital disorder caused by a teratogen. Fetal alcohol syndrome can often be recognised at birth. Not Teratogenic agents cause approximately 7% of congenital malformations. A teratogenic agent is a chemical, infectious agent, physical condition, or deficiency that, on fetal exposure, can alter fetal morphology or subsequent function. Teratogenicity depends upon the ability of the agent to cross the placenta. Certain medications such as heparin cannot cross the placenta due to its high molecula A teratogenic substance, or teratogen, are chemicals that affects the normal growth and development of a fetus. These abnormalities or malformation can even affect the viability of the pregnancy. It does not only apply to pharmaceutical drugs. Any substance that is dangerous to the fetus falls into this category, including alcohol, tobacco, illicit substances (street drugs), herbal medicines and certain nutritional substances. Some pesticides and certain food additives are also potentially.

TERATOGENS

Teratogenic agents cause approximately 7% of congenital malformations. A teratogenic agent is a chemical, infectious agent, physical condition, or deficiency that, on fetal exposure, can alter fetal morphology or subsequent function. Teratogenicity depends upon the ability of the agent to cross the placenta. Certain medications such as heparin cannot cross the placenta due t Many other sexually transmitted diseases are known teratogens also. Syphilis acts against brain development during the last 26 weeks of the pregnancy. Genital herpes is passed to the baby during a vaginal birth, causing blindness, brain damage and even death in over half of the infected babies. Gonorrhea contracted during birth can cause blindness in the infant. Cytomegalovirus can cause deafness, central nervous system damage and mental retardation

TORCH group infections (toxoplasmosis, others, rubella, cytomegalovirus, herpes) are the most serious infectious diseases during pregnancy due to the seriousness of possible embryo-fetal lesions. disease processes or external influences can also have tera-togenic effects on the fetus, such as diabetes or obesity. Many teratogens have been associated specifically with fetal cardiac malformation. Certain classes of medi-cations, including antibiotics, antiepileptic drugs (AEDs), antidepressants, nonprescription drugs, as well as certai Certain infections can be passed from child to adult, including chickenpox, rubella, and cytomegalovirus (CMV). Adults are immune to many of these diseases. In some cases, however, the exposure.

Teratogens are substances that may produce physical or functional defects in the human embryo or fetus after the pregnant woman is exposed to the substance. Alcohol and cocaine are examples of such substances. Exposure to the teratogen affects the fetus or embryo in a variety of ways, such as the duration of exposure, the amount of teratogenic. One example of this is the use of mammalian animal models to evaluate the molecular role of Teratogens in the development of embryonic populations, such as the Neural Crest, which can lead to the development of Neurocristopathies. Genetically modified mice are commonly used for this purpose. In addition, pregnancy registries are large, prospective studies that monitor exposures women receive during their pregnancies and record the outcome of their births. These studies provide. Examples include rubella , cytomegalovirus , genital herpes , toxoplasmosis , Fifth disease , chickenpox . Other, including diabetes , radiation, hyperthermia (high fever). The timing of foetal exposure to a teratogen is one of the major determinants of what effects the teratogen will have on prenatal development Page 1 of 32 Environmental Health and Safety 2408 Wanda Daley Drive Ames, Iowa 50011-3602 Phone (515) 294-5359 www.ehs.iastate.edu Carcinogens, Reproductive Toxins, and Teratogen teratogenic drugs A teratogen is an agent that can disturb the development of the embryo or fetus, resulting in spontaneous abortion, congenital malformations, intrauterine growth retardation, mental retardation, carcinogenesis, or mutagenesis. 1, 2 Known teratogens include radiation, maternal infections, chemicals, and drugs

A teratogen is any agent that causes harmful fetal effect or birth defect following fetal exposure during pregnancy. Teratogens are usually discovered after an increased prevalence of a particular birth defect. For example, in the early 1960's, a drug known as thalidomide was used to treat morning sickness. Exposure of the fetus during this early stage of development resulted in cases of phocomelia, a congenital malformation in which the hands and feet are attached to abbreviated arms and. Substances with teratogenic effects can be harmful to the development of a fetus. Substances with teratogenic effects can damage the DNA of a developing fetus. They may cause anything from abnormal development of a limb to malformation of an organ, and the effects for the developing fetus can vary depending on the teratogen, the gestational age of the fetus, and other factors

Teratogens; Embryotoxins; Fetotoxins

Environmental factors, such as infections and drugs, can simulate genetic conditions, for example, when two or more children of normal parents are affected. It is important to remember that not everything that is familial is genetic. Parts of embryos and organs most sensitive to teratogenic agents during periods of rapid differentiation (see Fig. 1). Because molecular signaling and embryonic. Teratogenic alleles interact with modifying and specificity alleles that act in the fetus and with environmental factors. Based on examples of the model, two candidate mechanisms emerge as contributors to neurodevelopmental disorders, folate-homocysteine pathways and immune/inflammatory mechanisms. Both, acting in mothers, affect fetal development and contain many polymorphic genes. These two systems interact with each other. Common functional polymorphisms of mild effect in these two.

Infective diseases during pregnancy and their teratogenic

Usually these abnormalities arise in the third to eighth weeks of pregnancy, when the major organ systems are forming. Examples of teratogens include certain chemicals, medications, and infections or other diseases in the mother. </p> Examples of Teratogens. There are many different examples of teratogens that cause birth defects. Listed in the directory below are some, for which we have provided a brief overview. Fetal Alcohol Syndrome (FAS) Phenytoin (Dilantin) Varicella. Ask a Medical Librarian Make an Appointment. Physicians & Services . Pediatricians who treat Genetic Related problems in Children; Pediatric Genetics at. Mothers can transfer a disease to their child in utero, and they can transfer some diseases during birth. These birth-transmitted diseases may cause minimal symptoms to the mother, but can cause permanent damage for the infant. Read More > Other Influences The mental health of the mother, her diet and her physical environment can all affect the embryo in her uterus. Depression has been shown. Examples of Iatrogenic Events Iatrogenic comes from the Greek language. Iatros means doctor or healer and gennan means as a result. Therefore, the word literally means as a result of a doctor. Iatrogenic events can be caused by any number of medical oversights or mistakes. They may occur during a hospital stay or a routine doctor's visit, and there is no single cause, medical.

Teratogens Factors Causing Physical Defects In Foetu

  1. Other examples of viral teratogens include herpes and rubella. In addition to bacteria and viruses, single-celled organisms called protozoa can be teratogenic during pregnancy, such as the.
  2. Teratogenic agents can be environmental chemicals, maternal metabolic factors, drugs, or infections. A number of environmental chemicals have been linked with birth defects in exposed fetuses including lead, methyl mercury, and polychlorinated biphenyls. Maternal metabolic factors associated with a significant risk of birth defects are maternal diabetes and maternal phenylketonuria. Excessive alcohol intake in pregnancy has been linked with fetal growth retardation, microcephaly, and cardiac.
  3. Other diseases are caused by acquired mutations in a gene or group of genes that occur during a person's life. Such mutations are not inherited from a parent, but occur either randomly or due to some environmental exposure (such as cigarette smoke). These include many cancers, as well as some forms of neurofibromatosis. List of Genetic Disorders. This list of genetic, orphan and rare diseases.
  4. Teratogenic exposure during any period or phase of development can have dire consequences . In general, disruption of the earliest developmental stages (gametogenesis; fertilization, cleavage, and blastulation) results in the loss of the conceptus (that is, a miscarriage, often before the woman realizes she is pregnant). Disruption somewhat later during primary morphogenesis and organogenesis.

James Graves Wilson's six principles of teratology, published in 1959, guide research on teratogenic agents and their effects on developing organisms.Wilson's six principles were inspired by Gabriel Madeleine Camille Dareste's five principles of experimental teratology published in 1877. Teratology is the study of birth defects, and a teratogen is something that either induces or amplifies. Benign liver tumors and hepatic cysts. Benign paroxysmal positional vertigo. Benign prostatic hyperplasia. Benign skin lesions. Benign tumors of the endometrium. Beta blockers. Beta-2 adrenergic agonists. Biceps tendon tear. Biliary cancer However, sometimes a medication necessary for health is also a teratogen: thyroid medication, blood thinners, and lithium are just a few examples. In these cases, female patients should work carefully with their doctors to determine if an alternative treatment is possible before and during pregnancy. In some cases the danger o Teratogens are agents that interfere with fetal development when exposed during pregnancy and cause abnormalities. Examples of these teratogens include, but are not limited to alcohol, smoking, and various prescription medications. The thalidomide tragedy is an unfortunate example of what teratogenic drugs can do to the development of fetuses. In the late 1950s and early 1960s, thalidomide was widely used for the treatment of nausea in pregnant women soon after, it became apparent.

these examples, the inherited gene clearly causes the disease or disorder. Although there are about sixty genetic causes of deaf-blindness (DB-Link, 2007), we have chosen only two illustrative syndromes. Our first example is CHARGE Association (syndrome), which represents a collection of physical irregularities present at birth. Thi Genetic diseases or disorders are caused due to abnormalities in the genetic makeup of an individual. Such abnormalities can be caused by a minuscule, major variation or mutation in single or multiple genes, chromosomal aberrations, and rarely due to mutations in the non-chromosomal DNA of mitochondria SAMPLE QUESTIONS FOR VIROLOGY MCQ's (MAC 221) Q-1 All the following viruses are transmitted by respiratory routes EXCEPT ONE: A) Human papilloma virus B) Rhinovirus C) Adenovirus D) Measles virus E) VZV Q-2 All the following viruses are disseminated throughout the body EXCEPT ONE: A) HIV B) HBV C) Rabies virus D) Yellow fever virus E) Human papilloma virus Q-3 An important defense function. Inhibiting the function of an enzyme may have teratogenic consequences. For example, methotrexate, an inhibitor of dihydrofolate reductase, an enzyme in the folic acid synthesis pathway, interferes with metabolic processes that require folic acid, including the synthesis of nucleotides needed to make DNA Teratogenic agents. Infectious agents . Some infections during pregnancy are teratogenic like viral infections (e.g. rubella, herpes simplex and cytomegalovirus), spirochetal infections (e.g. syphilis), and protozoal infestations (e.g. toxoplasmosis)

Birth defects associated with in utero exposure to higher doses of topiramate have been reported, but the teratogenic potential of lower doses is not known. Weight-loss drug combo nixed This is important because, with only two exceptions, all known human teratogens also are teratogenic in animals They are used in the treatment of a variety of diseases, such as inflammatory bowel disease, rheumatoid arthritis, hypertension and urinary tract infections. The second group of drugs may antagonize other enzymes in the folate metabolism, impair folate absorption or increase folate degradation. This group primarily consists of anti-epileptic drugs, including valproic acid, carbamazepine and phenytoin. The teratogenicity of folate antagonists in humans was first suggested by reports of women. A teratogen is any agent that causes an abnormality following fetal exposure during pregnancy. Teratogens are usually discovered after an increased prevalence of a particular birth defect. For example, in the early 1960's, a drug known as thalidomide was used to treat morning sickness. Exposure of the fetus during this early stage of development resulted in cases of phocomelia, a congenital.

While it has been used in a number of HIV-associated conditions, such use is associated with increased levels of the virus In addition, some teratogenic medications have a narrow window of exposure when their use results in malformations. For example, thalidomide is believed to produce malformations only when used 34-50 days after the beginning of the last menstrual period . In contrast, adverse outcomes such as growth retardation and functional abnormalities can.

No teratogenic effects occurred at lower doses. No reproduction studies with tau fluvalinate in other species were submitted and the compound has to be classified as possibly teratogenic.

A teratogenic agent is responsible for producing such a defect. The term survival, such as anencephaly; or one requiring major surgery for correction, such as cleft palate or congenital heart disease; or one producing major dysfunction (e.g., mental retardation). If minor malformations also are included, for example ear tags or extra digits, the rate may be as high as 7-10%. Drug. Thalidomide is a teratogenic drug, meaning that when taken while pregnant, it can have terrible impacts on fetal development and cause irreversible damages. Phocomelia, a limb atrophy, is the most common malformation linked to thalidomide, but all phocomelia cases aren't caused by thalidomide. However, due to the notoriety of the thalidomide tragedy, many people have started to associate it. 17 Teratogenic viruses, 31 Antonio V.
