Introduction
This disorder was clinically described (USA) in humans about 30 years ago (1973), while historically alcohol's teratogenic effects were identified in the early 20th century in a mix with the prohibition cause of the period.
Consuming alcohol during pregnancy is the cause of Fetal Alcohol Syndrome (FAS), consisting of a variable degree of birth defects and mental retardation, initially identified by a reduced head size and distinctive facial features.
Similar effects without the obvious alterations to appearance, but with nervous system effects, are sometimes typified as Fetal Alcohol Effects (FAE). Alcohol is able to cross the placenta from maternal circulation through the placenta into fetal circulation.
Exposure of embryos in vitro to ethanol simulates premature differentiation of prechondrogenic mesenchyme of the facial primordia.[2] This result may explain some facial abnormalities associated with FAS, the mechanism of which is still unknown.
Alcohol intake is also one of several factor known to impact upon birthweight. In Australia (2005) 6.4% of all liveborn babies were of low birthweight (less than 2,500 grams).
Cell death (apoptosis) induced by alcohol has also been suggested as relevant to craniofacial abnormalities and neurological development. The neurological effects (FAS limits IQ to around 70) may be due to cell death in the embryonic neuroepithelium (the outer layer of the developing neural tube) at an early developmental stage. Some additional evidence suggests that alcohol could also directly damage DNA.
These developmental abnormalities are maternal in origin and are not genetic, though there are probably genetic elements involved with alcoholism (More? OMIM alcoholism).
This Syndrome is 100% preventable.
Some Recent Findings
|
Fetal Alcohol Spectrum Disorders
"Fetal Alcohol Spectrum Disorders (FASD) is an umbrella term describing the range of effects that can occur in an individual whose mother drank alcohol during pregnancy. These effects may include physical, mental, behavioral, and/or learning disabilities with possible lifelong implications. The term FASD is not intended for use as a clinical diagnosis." [8]
Fetal Alcohol Effect (FAE), Alcohol-related Birth Defect (ARBD), and Alcohol-Related Neurodevelopmental Disorder (ARND) are terms also used to describe a the spectrum of conditions related to prenatal alcohol exposure.
About Alcohol
The pure chemical, alcohol is generally available in alcoholic beverages at between 0.5 - 40% concentration. Metabolic rates for alcohol differ between men and women and is also dependent on body size. (More? [../msds/alcohol.htm MSDS datasheet for alcohol])
The neurological euphoria induced by alcohol has been associated with the rapid release of dopamine in limbic areas of the brain.
Not all FAS babies are from alcoholics, but they do represent a significant population more at risk. The genetics of alcoholism are multifactorial, with several candidate genes identified as associated with the disease. (More? OMIM - Alcoholism)
Alcohol Statistics
Statistical information is often difficult to isolate directly, as alcohol is often combined with other drugs (tobacco, illicit drugs, etc).
There is an interesting "American paradox" that Americans have a relatively low rate of per capita alcohol consumption, yet the USA has the highest incidence of FAS (20 times all other countries) in the world.
USA studies by the CDC have reported FAS prevalence rates from 0.2 to 1.5 cases per 1,000 births across various populations. Disadvantaged groups, Native Americans and Australians, and other minorities have been documented to have rates as high as three to five FAS affected children per 1,000 children.[8]
Other studies reflecting a variety of ascertainment methodologies have produced estimates ranging from 0.5 to 2.0 cases per 1,000 live births. Using the CDC FAS estimates, among the approximately 4 million infants born each year, an estimated 1,000 to 6,000 will be born with FAS. Studies of particularly vulnerable populations yield prevalence estimates that far exceed those of other common disabilities.
Binge Drinking
Tracking binge drinking among U.S. childbearing-age women.[9] "The estimated binge drinking prevalence among childbearing-age women 18-44 years (USA) for the years 2001, 2002, and 2003 was 11.9%, 12.4%, and 13.0%, respectively. The estimated number of childbearing-age women who engaged in binge drinking rose from 6.2 million in 2001 to 7.1 million in 2003, an increase of 0.9 million."
FAS Diagnosis
There are a range of postnatal features which are used diagnostically including facial appearance and digit effects.
In addition, there are under development a number of different techniques which may be useful in the future for prenatal diagnosis.
Pregnancy characteristics of women giving birth to children with fetal alcohol syndrome in Far North Queensland.[10] "There is the potential to identify prospectively women presenting for antenatal care who are heavy drinkers and risk FAS in their infants, using the self-reported information about alcohol intake already being collected by our service; such women may then be offered specific interventions to try to reduce alcohol consumption in pregnancy."
Facial Appearance of FAS
Some, or all, of the following facial features are associated with FAS. There has also been a recent study to develop an automated facial analysis technique.[11]
FAS facial features[1]
- Microcephaly - leads to small head circumference
- Palpebral fissure - short opening of eye
- Epicanthal folds - fold of skin at inside of corner of eye
- Midface - flat
- Nasal Bridge - low
- Philtrum - Indistinct, vertical grooves between nose and mouth
- Upper Lip - thin
- Micrognathia - small jaw
- Ears - curve at top part of outer ear is underdeveloped and folded over parallel to curve beneath. Gives the appearance of a "railroad track"
Mouse Model
Variable midfacial dysmorphism and microcephaly in a/a offspring of mothers that consumed ethanol during gestation[5] |
FAS Digital Effects
In addition to the distinct facial effects, there may also be abnormalities associated with the digits, fingers or toes.
- Camptodactyly - permanent flexion contracture of a finger or toe
- Clinodactyly - permanent curving of the fifth finger (usually toward the other fingers) also seen for other fingers or toes
- Palmar crease - transverse flexion crease of the palm close to the fingers, described as "Hockey stick", widens like the end of a hockey stick and ends between the second and third fingers

2005 Canadian Guidelines
Fetal alcohol spectrum disorder: Canadian guidelines for diagnosis[14] "The guidelines are based on widespread consultation of expert practitioners and partners in the field. The guidelines have been organized into 7 categories: screening and referral; the physical examination and differential diagnosis; the neurobehavioural assessment; and treatment and follow-up; maternal alcohol history in pregnancy; diagnostic criteria for fetal alcohol syndrome (FAS), partial FAS and alcohol-related neurodevelopmental disorder; and harmonization of Institute of Medicine and 4-Digit Diagnostic Code approaches. The diagnosis requires a comprehensive history and physical and neurobehavioural assessments; a multidisciplinary approach is necessary."

26 August 2008 Draft Australian alcohol guidelines for low-risk drinking[15] "Following the initial consideration by the NHMRC Council, NHRMC is finalising the NHMRC Australian alcohol guidelines for low risk drinking, including the latest research. The Council is expected to consider them again in late 2008."

Finland
Fetal alcohol spectrum disorders in Finland: clinical delineation of 77 older children and adolescents.[17] "We have recently completed dysmorphology examination and parent/guardian interviews of the 77 children in the Finnish cohort. ...Although 11% were born prematurely, 70% demonstrated prenatal growth deficiency, and 45% were microcephalic. Other than growth deficits and the cardinal facial features, the most common major and minor anomalies noted were: camptodactyly (55%), "hockey stick" or other altered palmar creases (51%), refractive errors (40%), strabismus (38%), dental crowding (43%), nail hypoplasia (38%), GU anomalies (22%), and congenital heart defects (18%), "Railroad track" ears were not observed in this population."
Brain Development
New brain imaging techniques have allowed greater insight into the effects of alcohol on the brain. In FAS children this includes qualitative and quantitative studies of the postnatal brain including changes include anatomical displacements (corpus callosum) and changes in the neural layer (gray matter) density of the brain.
Abnormal cortical thickness and brain-behavior correlation patterns in individuals with heavy prenatal alcohol exposure.[18] "Significant cortical thickness excesses of up to 1.2 mm were observed in the FASD subjects in large areas of bilateral temporal, bilateral inferior parietal, and right frontal regions."
Teratogenic effects of alcohol: a decade of brain imaging.[19] "Results indicated displacements in the corpus callosum, increased gray matter densities in both hemispheres in the perisylvian regions, and altered gray matter asymmetry in portions of the temporal lobes in the brains of alcohol-exposed subjects."
Sensory Development
Prenatal alcohol exposure delays the development of the cortical barrel field in neonatal rats.[20] "...our model system to examine the effect of prenatal alcohol exposure (PAE) on early somatosensory cortical development. ....These findings suggest that PAE delays the development of the somatosensory cortex (SI); such delays may interfere with timing and formation of cortical circuits."
Bone Development
Binge alcohol exposure during all three trimesters alters bone strength and growth in fetal sheep.[21] "Maternal bones were not different among groups. The higher alcohol dose resulted in reduced fetal femoral bone strength, whereas the tibial bone strength was lower when compared with the normal control subjects. In contrast, the lower alcohol dose increased fetal femoral strength compared to the normal control subjects. The alcohol-exposed fetal bones also tended to exhibit reduced lengths."
