Sub-Category:
Prenatal Conditions
Number of Conditions: 3
Neural tube defects (e.g., spina bifida, anencephaly)
Specialty: Genetics
Category: Prenatal and Reproductive Genetics
Sub-category: Prenatal Conditions
Symptoms:
abnormal spinal cord or brain development; open spinal cord (spina bifida); absence of major portions of the brain (anencephaly); paralysis; difficulty walking; hydrocephalus (fluid on the brain); bowel or bladder dysfunction in spina bifida
Root Cause:
Failure of the neural tube to close completely during embryonic development, typically occurring in the first month of pregnancy.
How it's Diagnosed: videos
Prenatal ultrasound, maternal blood tests measuring alpha-fetoprotein (AFP), and amniocentesis for diagnostic confirmation.
Treatment:
Prenatal surgery (for spina bifida), postnatal surgery to close defects, management of complications such as hydrocephalus, physical therapy, and assistive devices for mobility.
Medications:
Folic acid supplements are used preventively; for symptom management, antibiotics (to prevent infections) and medications for bladder or bowel dysfunction may be prescribed.
Prevalence:
How common the health condition is within a specific population.
Approximately 1 in 1,000 live births worldwide, with variations depending on geographic and socioeconomic factors.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Folic acid deficiency, maternal diabetes, obesity, certain medications (e.g., antiepileptic drugs), and family history of neural tube defects.
Prognosis:
The expected outcome or course of the condition over time.
Dependent on severity; anencephaly is not compatible with life, while spina bifida outcomes vary from mild impairment to significant disability.
Complications:
Additional problems or conditions that may arise as a result of the original condition.
Hydrocephalus, infections, mobility limitations, bowel and bladder dysfunction, and lifelong disability in severe cases.
Congenital Diaphragmatic Hernia
Specialty: Genetics
Category: Prenatal and Reproductive Genetics
Sub-category: Prenatal Conditions
Symptoms:
respiratory distress after birth; pulmonary hypoplasia (underdeveloped lungs); scaphoid abdomen; cyanosis (bluish skin due to lack of oxygen); bowel sounds in the chest
Root Cause:
Defect in the diaphragm allowing abdominal organs to migrate into the chest cavity, restricting lung development.
How it's Diagnosed: videos
Prenatal ultrasound showing abnormal organ placement, fetal MRI for detailed anatomy, or postnatal imaging such as chest X-rays.
Treatment:
Surgical repair after birth, often preceded by stabilization with mechanical ventilation or extracorporeal membrane oxygenation (ECMO). Prenatal interventions (e.g., fetoscopic tracheal occlusion) are experimental.
Medications:
Surfactant therapy to improve lung function, nitric oxide to manage pulmonary hypertension, and sedatives for mechanical ventilation.
Prevalence:
How common the health condition is within a specific population.
Approximately 1 in 2,500 live births worldwide.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Genetic syndromes, chromosomal abnormalities, maternal smoking, and exposure to environmental toxins during pregnancy.
Prognosis:
The expected outcome or course of the condition over time.
Dependent on severity and associated anomalies; survival rates are approximately 60–80% with modern interventions.
Complications:
Additional problems or conditions that may arise as a result of the original condition.
Chronic lung disease, pulmonary hypertension, feeding difficulties, and developmental delays.
Fetal Alcohol Syndrome
Specialty: Genetics
Category: Prenatal and Reproductive Genetics
Sub-category: Prenatal Conditions
Symptoms:
facial abnormalities (e.g., smooth philtrum, thin upper lip); growth deficiencies; developmental delays; intellectual disabilities; behavioral problems; poor coordination; vision or hearing problems
Root Cause:
Prenatal exposure to alcohol, which interferes with fetal brain and organ development.
How it's Diagnosed: videos
Clinical evaluation of facial features, growth measurements, developmental assessments, and maternal history of alcohol consumption during pregnancy.
Treatment:
Symptom management through special education services, behavioral therapies, and medical management for associated conditions (e.g., ADHD, sensory deficits).
Medications:
Psychostimulants (e.g., methylphenidate ) for ADHD symptoms, antidepressants (e.g., fluoxetine ) for mood disorders, and antipsychotics (e.g., risperidone ) for behavioral problems.
Prevalence:
How common the health condition is within a specific population.
Estimated at 0.2–1.5 per 1,000 live births in developed countries.
Risk Factors:
Factors or behaviors that increase the likelihood of developing the condition.
Maternal alcohol use during pregnancy, especially binge drinking or chronic alcohol consumption.
Prognosis:
The expected outcome or course of the condition over time.
Lifelong condition with challenges in learning, social interactions, and independence, but early interventions can improve quality of life.
Complications:
Additional problems or conditions that may arise as a result of the original condition.
Learning disabilities, behavioral problems, difficulty with independent living, mental health disorders, and social difficulties.
