Have a question? Teratogen causing: congential anomalies and typical facies. You can help advance Chromosome cohesion defects are seen in cells from RBS/SCP probands demonstrating “heterochromatic repulsion” by premature sister chromatid separation, primarily at the centromeric regions on prophase and metaphase chromosomes (88). Purines – guanine, adenine. These effects may be reversible. Affected individuals usually have a mild form of hemoglobin H (Hb H) disease. 2007), the FGF2 target offers a possible mechanism to explain the thalidomide-induced CHDs. Toxicity refers to these sometimes deadly effects: though all drugs have adverse effects at normal doses, it is only the dangerous ones which are referred to as toxic. Birth defects associated with the use of thalidomide during the first trimester include phocomelia, duodenal stenosis, esophageal fistula, neural tube defects, microphthalmia, deformities of the pinnae of the ears, and mid-line hemangiomas [118]. What is a likely cause for a badly turned-in ankle in a newborn? In 1937 the sulphanilamide elixir causing 105 deaths as a result of poisoning due to a lack of formulation enabled the improvement of pharmaceutical regulation. Humans take a number of drugs for health reasons, it is practically guaranteed that all useful drugs will produce unwanted effects, but some can produce positively dangerous effects. The majority of thalidomide embryopathy survivors have some form of limb deformity. Search . Before the introduction of thalidomide, phocomelia was a rare malformation [119]. M.A. *amelia (ă-*mee*-liă) n.* congenital total absence of the arms or legs due to a developmental defect. There will likely be tissue-specific differences in the downstream signaling changes following thalidomide exposure (Vargesson, 2009). The kidneys can be injured in diverse ways by many drugs, both legal and illegal. The hypothesis is that signaling between the AER and limb mesenchyme recovers, after thalidomide exposure and loss of cell populations destined to form the proximal limb elements, leaving the remaining cells to pattern distal elements under the control of the AER (Figure 31.2B; Therapontos et al., 2009; Vargesson, 2009). A 2004 study by Francisco Chung, Lai-Ming Ching, and colleagues in New Zealand argued that the half-life of Thalidomide in mouse embryos was approximately half an hour while that of human embryos was 7.3 hours. The Drosophila Eco1 ortholog specifically establishes cohesion at centromeres, and not along the chromosome arms (107). S.M. Although various factors are now known to cause phocomelia, the prominent roots of the disease can be found in the use of the drug thalidomide. Finally, in an ironic turn thalidomide is currently being evaluated clinically for its ability to counteract the inflammatory events that contribute to congestive heart failure (reviewed in Aukrust et al. At 8 weeks of gestation, after the pregnancy had been diagnosed, haloperidol and fluphenazine were withdrawn and trifluoperazine 5 mg was started and continued until 8 weeks before the baby was born. She said that the defect was caused by the drug that made her nauseated. Teratogens include irradiation, chemicals (drugs), and infectious agents. Recently, in a limb model thalidomide enhances Bmp signals and represses canonical Wnt signal (Knobloch et al. Phocomelia is a severe shortening of the limbs, where distal elements (handplate) remains but proximal elements (long bones) are reduced or missing [ … Matthew A. Deardorff, Ian D. Krantz, in Emery and Rimoin's Principles and Practice of Medical Genetics, 2013. Questions sent to GARD may be posted here if the information could be helpful to others. Arthur J. Instances of dextrocardia, cardiomegaly, and abnormal patterning of the coronary arteries were also observed. 2007). According to Anthony J Perri III, and Sylvia Hsu they can additionally receive: Palsy disorder of the face You are asked to be a witness for the manufacturer. She gave birth to an infant who had a septal defect of the heart and sued the manufacturer of the drug. Surprisingly, there is no clear consensus on the mechanism/s of thalidomide action. A simple nevus extending from the forehead over the nose down to the upper lip is a characteristic feature. This chapter reviews principles of teratology and discusses drug use in pregnancy. Dr.McBride ... Hamburg University was also investigating clusters of phocomelia, a previously rare birth deformity in Nevertheless, there have been isolated case reports of malformations [610]. In some cases, the hand or foot is attached to the end of the shortened appendage, but in other cases there is no hand or foot at all. Overview. placeholder for the horizontal scroll slider, Office of Rare Disease Research Facebook Page, Office of Rare Disease Research on Twitter, U.S. Department of Health & Human Services, Caring for Your Patient with a Rare Disease, Preguntas Más Frecuentes Sobre Enfermedades Raras, Como Encontrar un Especialista en su Enfermedad, Consejos Para una Condición no Diagnosticada, Consejos Para Obtener Ayuda Financiera Para Una Enfermedad, Preguntas Más Frecuentes Sobre los Trastornos Cromosómicos. Of interest, studies in zebra fish demonstrated a very different pattern of gene dysregulation in RBS/SCP from that seen in CdLS, with many dysregulated genes involved in cell cycle and apoptotic pathways (110). No etiological agent was discovered in the other two, both of whom died. Thalidomide, or α-phthalimidoglutarimide, is a potent human teratogen best known for causing limb malformations (, Principles of Clinical Pharmacology (Third Edition), Few drugs have focused as much public attention on the problem of adverse drug reactions as thalidomide, which was first linked in 1961 to catastrophic outbreaks of, Physically milder CdLS, significant cognitive impairment, Physically milder CdLS, significant cognitive impairment (only one proband identified), No established genotype-phenotype correlation, α-Thalassemia/mental retardation syndrome, X-linked, Abnormal lobulation of the right lobe of the liver. Collin Dollery and Folke Sjöqvist established similar programs in Europe. Nonetheless, in low-income countries thalidomide embryopathy still occurs due to inadequate safeguards and black-market sales (Schuler-Faccini et al. When an individual is born with phocomelia due to drugs or pharmaceuticals, it is known as thalidomide syndrome. Syndactyly and polydactyly were common. In the third chapter, which is still being written, genetic approaches are being developed and applied both to meet this challenge and to improve the efficacy and safety of drug therapy [11]. A sedative originally used in pregnancy for its antinausea properties, more recently thalidomide was discovered to have potent anti-inflammatory properties, and it is again in clinical use for treatment of leprosy, AIDS-related disorders, cancers including myelomas, and graft rejection (reviewed in Nasca et al. A. Phenytoin B. Lithium C. Valproate D. Phenobarbitone. Pyrimidines – cytosine, thymidine, uracil. Smithells (1973) also reported a 45% mortality rate in 29 cases in the United Kingdom; similarly, the surviving cohort of 154 children had only 14 instances of CHD (Smithells 1973). According to Anthony J Perri III, and Sylvia Hsu they can additionally receive: [citation needed] Palsy disorder of the face Some drug toxicities are predictable in foetal life: ACE inhibitors causing renal impairment and opiates causing dependence. Do you know of a review article? Occasionally all four limbs are virtually absent. Thalidomide, a sedative to ease morning sickness in pregnant women, was banned more than a half century ago due to causing a severe birth defect known as phocomelia. Phocomelia is defined as the loss of or severe shortening of the long bones of the limb (upper and/or lower). The clinical features of this syndrome are distinct from CdLS but display systemic overlap (104). Proteomics is the general approach to identifying and quantifying all proteins of a cell, a tissue, an organ or the whole organism at a defined state. There have been reviews of neuroleptic drug use during pregnancy [606–609]. She was given oral haloperidol 1.5 mg at 12-hourly intervals. According to Anthony J Perri III, and Sylvia Hsu they can additionally receive: Palsy disorder of the face Claim: A rapidly approved drug known as thalidomide was not rigorously tested before being prescribed to pregnant women, ultimately leading to \u201cmalformations in newborns\u201d born to women wh… The child was born with phocomelia of the left arm, with an extremely short humerus and an absent forearm. Table 1. Researchers may have finally figured out the mechanism of the tragic birth defects caused by thalidomide, the drug taken by pregnant women in the late 1950s as a remedy for nausea: It is thought to have inhibited development of new blood vessels at a crucial stage in the pregnancy. However, most large-scale controlled studies have shown that they can be used safely during pregnancy [185]. Ruffing (1977) placed the incidence of CHDs at 30% at birth, but only 13 of 200 surviving children had CHDs. Trimethadione. Few drugs have focused as much public attention on the problem of adverse drug reactions as thalidomide, which was first linked in 1961 to catastrophic outbreaks of phocomelia by Lenz in Germany and McBride in Australia [8]. AtkinsonJr., in Principles of Clinical Pharmacology (Third Edition), 2012. Traditionally, the Food and Drug Administration (FDA) placed medications into five categories based on their potential . At other times, the effects of drugs are more subtle. When an individual is born with phocomelia due to drugs or pharmaceuticals, it is known as thalidomide syndrome. Phocomelia is a condition that involves malformations of human arms and legs. The Effects of Maternal Drugs on the Developing Fetus David A. Beckman Lynda B. Fawcett Robert L. Brent Every conception has a risk of ending in abortion or serious congenital anomaly (Tables 15-1,15-2). Furthermore it is axiomatic that every drug administered or taken by a pregnant woman presents the mother and fetus with both risks… Which of these anomalies can be attributed to a disturbance in tissue resorption? Internal symptoms may also present in cases of phocomelia syndrome including defects of the heart, kidneys, digestive tract, lungs, genitalia and more. Of 96 children with congenital limb deformities who were born in 1962–63, 68 had a history of thalidomide administration during the first trimester [123]. The most common CHDs mentioned were conotruncal defects, ASDs, and VSDs; fatal ‘complex cyanotic lesions’ that were uncorrectable by surgery were also noted (Smithells 1973). The majority of these symptoms are related to the cases caused by thalidomide. Reproductive and Developmental Toxicology, Meyler's Side Effects of Drugs (Sixteenth Edition), Systemic Approach to Differential Diagnosis, Small Animal Medical Differential Diagnosis (Third Edition), Human Embryology and Developmental Biology (Fifth Edition), Emery and Rimoin's Principles and Practice of Medical Genetics, Birth defects associated with the use of thalidomide during the first trimester include. In 1961 thalidomide causing phocomelia in infants whose mothers took the drug. Phocomelia occurs through a severe shortening of the limb/s, due to proximal elements (long bones) being reduced or missing and leaving distal elements (handplate) in place. Phocomelia refers to short or absent long bones with the hands extending in a “flipper-like” form. Thalidomide’s Birth-Defect-Causing Mechanism Finally Uncovered. Thalidomide: phocomelia, limb reduction defects, ear/nasal anomalies, cardiac defects, pyloric or duodenal stenosis Trimethadione: facial dysmorphism (short upturned nose, slanted eyebrows),cardiac defects, IUGR, intellectual disability Tolulene. General ignorance of basic and applied pharmacology and therapeutic principles. In 21 cases the ears were imperfectly developed without impaired hearing. The consistent features seen in RBS include pre- and postnatal growth retardation, microcephaly, bilateral cleft lip and palate, symmetric mesomelic limb shortening (‘phocomelia’), genitourinary abnormalities, and congenital heart defects. Although studies have failed to identify an increased rate of malformations with haloperidol, isolated cases have been reported [606,609,612]. Such an understanding should shed light on improving therapeutic uses for the drug and insight into producing potentially safer forms of the drug. A new study has shown that most mutations in ESCO2 identified in RBS probands result in disruption of the acetyltransferase domain. Phocomelia is a congenital disorder that presents with a reduction in length of the long bones of the legs and/or arms. A German newspaper soon reported 161 babies were adversely affected by thalidomide, leading the makers of the drug—who had ignored reports of the birth defects associated with the it—to finally stop distribution within Germany. If you do not want your question posted, please let us know. This act greatly expanded the scope of the FDA’s mandate to protect the public health. It became apparent in the 1960s that thalidomide treatment resulted in severe birth defects in thousands of children. Its teratogenic action in the limb may instead lie in its ability to block FGF2-mediated angiogenesis (D’Amato et al. Their accomplishments include the invention of the double-blind design for clinical trials [6], the use of effect kinetics to measure the absolute bioavailability of digoxin and characterize the time course of its chronotropic effects [7], and the founding of Clinical Pharmacology and Therapeutics. (Photos courtesy of Dr Hugo Vega). Current thinking suggests that phocomelia arises due to a loss of cells that should produce the long bones of the limb, early in development (Galloway et al., 2009; Therapontos et al., 2009). The fact that most adverse drug reactions occur with commonly used drugs focuses attention on the last of the preventable causes of these reactions: the training that prescribing physicians receive in pharmacology and therapeutics. In budding yeast, Eco1 acetylates Smc3’s head domain in a cell-cycle-dependent manner to promote sister chromatid cohesion (77,78). The drug increases rates of fetus mortality and can cause phocomelia, a rare congenital deformity in which the hands or feet are attached close to the body and or the limbs are grossly underdeveloped or absent. It describes an extremely rare condition in which babies are born with limbs that look like flippers. Purines – guanine, adenine. Although the enantiomers of chiral drugs have the same chemical connectivity of atoms, they tend to differ greatly in their pharmacokinetic and pharmacodynamic properties. See also phocomelia … The limb is, therefore, extremely shortened and in severe cases, the hand or foot may be attached directly to the trunk. Roberts/SC phocomelia syndrome (RBS/SCP OMIM #268300) is an autosomal recessive genetic disorder caused by homozygous or compound heterozygous mutations in the ESCO2 gene. The exposure window for thalidomide-induced heart defects is 36–45 days post-menstruation (22–32 days post-implantation; Newman 1986). These drugs resemble nucleotides/bases of DNA or RNA – blocking enzymes needed for DNA synthesis or being incorporated into DNA or RNA; interfering in replication or causing apoptosis. Although various factors are now known to cause phocomelia, the prominent roots of the disease can be found in the use of the drug thalidomide. According to Anthony J Perri III, and Sylvia Hsu they can additionally receive: Palsy disorder of the face You are asked to be a witness for the defense. Effects of drug were usually bilateral, especially in upper extremity A 38-year-old woman was admitted to hospital in the third week after conception and acute schizophrenia was diagnosed. Thus, thalidomide offered one of the first clear demonstrations of the teratologic principle that exposure period had to temporally correspond with formation of the relevant structures. Anabolic androgenic steroids, illicitly used by athletes and others for decades to increase muscle mass and decrease body fat, are emerging as podocyte toxins given … We want to hear from you. In fission yeast, Eco1 physically interacts with Pds5 to counteract its inhibition of cohesion (106). Correct answer : C. Valproate Valproate is a teratogenic drug which causes spina bifida and other neural tube defects in the fetus when taken by pregnant women. The differential diagnosis between the Stilling–Türk–Duanesches syndrome and thalidomide embryopathy has been detailed, following a review of the case history of a boy with multiple congenital abnormalities [127]. The symptoms of thalidomide syndrome are defined by absent or shortened limbs; causing flipper hands and feet. Pyrimidines – cytosine, thymidine, uracil. 2007). A 3-year-old child is much smaller than normal, has sparse hair, and has irregular teeth. Phocomelia can also be caused by maternal exposure to certain drugs (such as thalidomide) during pregnancy. Roberts/SC phocomelia syndrome (RBS/SCP; OMIM #268300) is an autosomal recessive genetic disorder caused by homozygous or compound heterozygous mutations in the ESCO2 gene (102,103). For instance, thalidomide taken after 21 days of pregnancy will often lead to lack of external ears and paralysis of … When an individual is born with phocomelia due to drugs or pharmaceuticals, it is known as thalidomide syndrome. ATRX is caused by mutations in the ATRX gene on the X chromosome (Table 1). Mark S. Thompson DVM, in Small Animal Medical Differential Diagnosis (Third Edition), 2018, Hemimelia, phocomelia, amelia: absence of portions or entire limb (amelia), Syndactyly: fusion of two or more digits; rarely clinically significant, Ectrodactyly: third metacarpal and digit missing forming a cleft (split or “lobster” claw), Osteopetrosis: rare; diaphysis remains filled with bone, marrow does not form, fragile bones, Osteogenesis imperfecta: heritable diseases—fragile bones, Mucopolysaccharidosis: rare lysosomal storage disease—Siamese cats—causes dwarfism, facial dysmorphism, Craniomandibular osteopathy (West Highland White Terrier, Scottish Terrier, Cairn Terrier, Boston Terrier, other terriers), Bruce M. Carlson MD, PhD, in Human Embryology and Developmental Biology (Fifth Edition), 2014. 7 Within a few years of the widespread use of thalidomide in Europe, in which the hands or feet are attached close to the body and or the We remove all identifying information when posting a question to protect your privacy. This unstructured process of learning pharmacotherapeutic technique stands in marked contrast to the rigorously supervised training that is an accepted part of surgical training, in which instantaneous feedback is provided whenever a retractor, let alone a scalpel, is held improperly. What is your case? The results are summarized in Table 2. 30 Sometimes these effects can be dramatic, as seen with thalidomide, resulting in phocomelia, and retinoic acid, causing facial cleft malformations. According to Anthony J Perri III, and Sylvia Hsu they can additionally receive: Palsy disorder of the face An increased incidence of what condition is strongly associated with increasing maternal age? Cleft palate is the result of a defect in what developmental mechanism? A woman who was in a car accident and sustained abdominal bruising during the fourth month of pregnancy gave birth to an infant with a cleft palate. 2008). Most US medical schools provide their students with only a single course in pharmacology that traditionally is part of the second-year curriculum, when students lack the clinical background that is needed to support detailed instruction in therapeutics. Phocomelia remains the most striking limb deformity caused by thalidomide, and remains the stereotypical image of thalidomide embryopathy. Phocomelia is the striking characteristic of thalidomide embryopathy which remains the public image of the condition and disaster. Occurrence in an individual results in various abnormalities to the face, limbs, ears, nose, vessels and many other underdevelopments. These drugs resemble nucleotides/bases of DNA or RNA – blocking enzymes needed for DNA synthesis or being incorporated into DNA or RNA; interfering in replication or causing apoptosis. (A) Shortening of long bones of arms with contractures seen in SC phocomelia. The commonest abnormalities are agenesis or malformations of the upper and lower limbs; the eyes, ears, and internal organs can also be involved [108]. In response to the public mandate generated by the thalidomide catastrophe, these leaders quickly reached consensus on a number of theoretically preventable causes that contribute to the high incidence of adverse drug reactions [5]. This results in faulty cohesion and other cellular events in RBS cell lines, indicating the acetyltransferase activity contributes to the development of the major organ systems affected in RBS (108,109). When scientists blocked the antioxidant glutathione from binding to its receptors in laboratory mice, they counteracted the mice's resistances to Thalidomide, a result that indicates that glutathione helps to repress Thalidomide's effects. Currently marketed under the brand names Inmunoprin, Talidex, Talizer, Thalomid) is an immunomodulatory drug and the prototype of the thalidomide class of drugs. Testosterone like drugs. rare disease research! Of 285 cases, 251 had upper-limb defects and 146 upper-limb defects alone. It describes an extremely rare condition in which babies are born with limbs that look like flippers. ... causing an unwanted or toxic effect. Phocomelia is a devastating, rare congenital limb malformation in which the long bones are shorter than normal, with the upper portion of the limb being most severely affected. Teratogenic effects are usually specific to a drug and a time of gestation: thalidomide causing phocomelia when exposure occurs in weeks 4 to 7. In the earliest chapter, laboratory methods were developed to measure drug concentrations in patient blood samples and to guide therapy – an approach now termed “therapeutic drug monitoring” [10]. Pregnancy Category X - Have such a high risk of causing permanent damage to the fetus that they should NOT be used in pregnancy or when there is a possibility of pregnancy. Teratogen causing: Fetal alcohol-like syndrome and pre-term labor. Known teratogenic agents capable of causing phocomelia are reviewed, but no clear association with the two cases described in this report is evident. Thalidomide became one of the world's largest selling drugs, and was marketed heavily and advertised as completely safe (Vargesson, ... Phocomelia remains the most striking limb deformity caused by thalidomide, and remains the stereotypical image of thalidomide embryopathy. Phocomelia syndrome. A woman who took a new sedative during the second month of pregnancy felt nauseated after ingestion of the drug and stopped taking it after a couple of weeks. A 2008 study by Knoblach and colleagues demonstrated how superoxides can prevent Thalidomide from causing apoptosis. In addition, Sjöqvist [14] has observed that most academic pharmacology departments have lost contact with drug development and pharmacotherapy. Early in gestation, there are periods of critical importance for structural development that can be interrupted by drug exposure. This point becomes relevant below. Phocomelia associated with neuroleptic drugs has been reported [613]. The symptoms of thalidomide syndrome are defined by absent or shortened limbs; causing flipper hands and feet. The symptoms of thalidomide syndrome are defined by absent or shortened limbs; causing flipper hands and feet. FIGURE 164-6. Its immunosuppressive action may be due to its repression of the inhibitor of kappa B (IκB) kinase and subsequent reduction in NF-κB activation and TNFα production (reviewed in Melchert and List 2007). If you have questions about which treatment is right for you, talk to your healthcare professional. Phocomelia syndrome:- Phocomelia is a congenital disorder involving the limbs (dysmelia). Capecitabine is a prodrug of 5-fluorouracil. Furthermore, CPS49 causes vessel loss in the forming chick limb followed by massive mesenchymal cell death and a disruption of limb signaling pathways, resulting in a range of severely truncated limbs with some that look remarkably like phocomelia (Figure 31.2B; Therapontos et al., 2009). This hydroxylated intermediate then acts as an Correct answer : C. Valproate. potential of the commonly prescribed psychotropic drugs (Table 1) and then in light of that literature review the present case. 2008). This suggests that cell proliferation defects and apoptosis may play a significant role in the RBS/SCP phenotype rather than gene dysregulation as suggested in CdLS (110). C-Drugs may cause harm to the fetus without causing birth defects . Estimates are that 10–50% of all pregnancies exposed to thalidomide during the critical period resulted in some form of malformation (Newman 1986). What is a likely basis for this constellation of defects? Capecitabine is a prodrug of 5-fluorouracil. Within a few years of the widespread use of thalidomide in Europe, Australia, and Japan, approximately 10,000 children were born with phocomelia, leading to the ban of thalidomide in most countries in 1961. In 92 cases both the upper and lower limbs were affected and in five cases only the lower limbs were involved. These include: Failure of prescribing physicians to establish and adhere to clear therapeutic goals, Failure of medical personnel to attribute new symptoms or changes in laboratory test results to drug therapy, Lack of priority given to the scientific study of adverse drug reaction mechanisms. The greater the half-life, the longer Thalidomide remains active, thereby causing more damage over a longer period of time. Stephens et al. Thalidomide was first marketed in the late 1950s as a sedative and was used in the treatment of nausea in pregnant women ().Within a few years of the widespread use of thalidomide in Europe, Australia, and Japan, approximately 10,000 children were born with phocomelia, leading to the ban of thalidomide in most countries in 1961. The term teratogen usually is cited in the context of causing anatomical defects in an embryo that was previously differentiating normally. It is one of the fetal abnormalities induced by the drug thalidomide taken early in pregnancy. This event allowed WHO to create an international drug surveillance program (the … Thus, pharmacogenetics is being used to identify slow drug-metabolizing patients who might be at increased risk for drug toxicity and rapid metabolizers who might not respond when standard drug doses are prescribed. Thalidomide was a widely used drug in the late 1950s and early 1960s for the treatment of nausea in pregnant women. Currently marketed under the brand names Inmunoprin, Talidex, Talizer, Thalomid) is an immunomodulatory drug and the prototype of the thalidomide class of drugs. The thalidomide tragedy also provided the major impetus for developing a number of NIH-funded academic centers of excellence that have shaped contemporary clinical pharmacology in this country. Abnormalities in children with congenital limb deformities. Bucheim’s comparison of surgery and medicine is particularly apt in this regard [5]. Various etiological factors are contributing to Phocomelia, the main etiological factor being use of teratogenic drug thalidomide [1]. However, high thalidomide doses have been associated with bradycardia (Meyer et al. hello friends today we are going to talk about Teratogenic drugs causing specific syndromes during pregnancy Alcohol: fetal alcohol syndrome—IUGR, midfacial hypoplasia, developmental delay, short palpebral fissures, long philtrum, multiple joint anomalies, cardiac defects The mother had taken thalidomide in early pregnancy [126]. The word “phocomelia” means seal limb. The word “phocomelia” means seal limb. Recognition of the considerable variation in response of different patients treated with standard drug doses has provided the impetus for the development of what is currently called “personalized medicine” [11]. for causing birth defects (Table 2) [16]. Perhaps, the most striking and defining characteristic of thalidomide embryopathy are the phocomelic limbs of survivors. What is your case? https://www.orpha.net/data/patho/Pro/en/Phocomelia-En.pdf. An individual exhibiting phocomelia may be referred to as a phocomelus. Two most common causes of Phocomelia are genetic inheritance and drug use. Three cases of congenital limb deformity after the administration of thalidomide-containing formulations during the first trimester were the first of this kind to be reported from the UAR and Kuwait [124]. However, if it is part of a genetic syndrome, surgical intervention may be recommended for … Importantly, Vickers noted that in some animals the outflow tract cushions had an abnormal ‘fibrocellular’ appearance and suggested that thalidomide adversely affected cushion development. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. As the opening quotation indicates, the concern of pharmacologists for the safe and effective use of medicine can be traced back at least to Rudolph Bucheim (1820–1879), who has been credited with establishing pharmacology as a laboratory based discipline [1]. Lithium can cause fetal goitre and cardiac abnormalities. Whether this may also contribute to its cardiac teratogenicity is unknown. Exposure of chick embryos on days 2, 3, or 4 of incubation produced with relatively equivalent frequency VSDs (both muscular and membranous) and conotruncal malformations including aortic stenosis, common truncus arteriosus, and malformations of the aortic and pulmonary valves (Gilani, 1973).
