Congenital Diseases and Disorders Flashcards
Description: clumping red blood cells, damaging blood vessels, highest among those of African descent.
Sickle Cell Anemia
Etiology: condition due to abnormal form of hemoglobin, called hemoglobin S, within the red cells. If two individuals with this trait marry, their offspring has a 25% chance of inheriting it. (1 out of 4)
Sickle Cell Anemia
Signs/Symptoms: anemic, attacks of intense pain in the arms, legs or abdomen. jaundice in eye. Recurrent bouts of fever, chronic fatigue, dyspnea, tachycardia, cardiac murmurs, and pallor. Infections, stress, and extremes in temperature may trigger the painful crises.
Sickle Cell Anemia
Diagnostic Procedures: If parents are known carriers, infants should be screened. Hematocrit. Laboratory tests.
Sickle Cell Anemia
Treatment for Sickle Cell Anemia
Symptomatic. Analgesics, adequate hydration, Bone marrow transplant may be curative. Chronic transfusions may also be ordered.
Prevention for Sickle Cell Anemia
No Prevention. Genetic. Eating a healthy, balanced diet, taking vitamins including a folic acid supplement, drinking plenty of fluids, avoiding extremes in temperatures, getting moderate exercise and plenty of rest.
Description: defects of the first month of pregnancy. Incomplete closure of the bones encasing the spinal cord.
Neural Tube Defects: Spina Bifida, Meningocele, and Myelomeningocele.
Incomplete closure of one or more vertebrae, with NO protrusion of the spinal cord or the membranes covering the brain and spinal cord.
Spina Bifida
Protrusion of the spinal fluid and meninges
Meningocele
Results when the external sac contains meninges, cerebral spinal fluid, a portion of the spinal cord, or its nerve roots.
Myelomeningocele
Etiology: 20 and 23 days gestation. Failure to close. lack of folic acid in pregnant women’s diet.
Neural Tube Defects: Spina Bifida, Meningocele, and Myelomeningocele.
Signs/Symptoms: Dimple in the skin, Partial paralysis and bladder and bowel dysfunction. Twisted or abnormal legs and feet, (club foot), And Chari malformation. (back portion of the brain is pushed through the hole in the bottom of the skull.
Neural Tube Defects: Spina Bifida, Meningocele, and Myelomeningocele.
Diagnostic Procedures for Neural Tube Defects: Spina Bifida, Meningocele, and Myelomeningocele
Prenatal detection. Ultrasonographic examination. X-ray.
Treatment for Neural Tube Defects: Spina Bifida, Meningocele, and Myelomeningocele
There is no cure. Surgical repair
Prognosis for Neural Tube Defects: Spina Bifida, Meningocele, and Myelomeningocele.
Dependent on the extent of neurological deficit. Best prognosis with Spina Bifida, worst prognosis with Myelomeningocele.
Prevention of Neural Tube Defects
Administering folic acid to pregnant women.
Description: Too much cerebrospinal fluid (CSF) in the ventricles of the brain. Ventricles expand beyond the point of obstruction, the cranial sutures separate, the head expands, and the fontanels “soft spots” bulge.
Hydrocephalus
Etiology: Genetic defect. developmental disorder. May be caused by traumatic head injury, diseases such as meningitis or tumors, or intraventricular or subarachnoid hemorrhages.
Hydrocephalus
Signs/Symptoms: Head will become enlarged, infants often have high-pitched cries and abnormal muscle tone in their legs. Projectile vomiting, irritable, and very sleepy. older children and adults will have a headache, nausea, vomiting, blurred or double vision, problems with balance, coordination, and walking.
Hydrocephalus
Diagnostic Procedures for Hydrocephalus
Neurological assessment, Ultrasonography, MRI, CT scan
Treatment for Hydrocephalus
Surgical correction. Shunt is placed from the affected ventricles of the brain into the peritoneal cavity, or into the right atrium of the heart.
Prognosis for Hydrocephalus
Cognitive and physical developmental difficulties, vision loss, and impaired motor function.
Prevention for hydrocephalus
Regular prenatal care, protection from head injuries, up to date immunizations.
Description: nonprogressive paralysis from developmental defects of the brain, or from trauma during or after birth.
Cerebral Palsy
Etiology: prior to birth, maternal rubella, maternal diabetes, anoxia, toxemia, preeclampsia. 10% of causes relate to the birth process and include trauma during delivery, prematurity, or asphyxia from umbilical cord becoming wrapped around infants neck. Postnatal causes include head trauma, meningitis, or poisoning.
Cerebral Palsy
What are the three types of Cerebral Palsy?
Spastic, Athetoid, and Ataxic
What type of cerebral palsy has characteristics of Hyperactive reflexes, rapid muscle contraction, muscle weakness, spasticity, underdevelopment of limbs.
Spastic Cerebral Palsy
What type of Cerebral palsy has characteristics of involuntary muscle movements, slow and writhing, impaired muscle tone, dystonia, difficulty with speech.
Athetiod Cerebral Palsy
What type of Cerebral palsy has characteristics of difficulty in balance, depth perception, and coordination. rhythmic, involuntary movement of the eyeball, or nystagmus; muscle weakness and tremor. Sudden movements are almost always impossible.
Ataxic CP
What are the diagnostic procedures for Cerebral Palsy?
Neurological assessment, ultrasound, CT scan, MRI. Observed characteristics are: 1. Inability to suck or keep food in the mouth. 2. difficulty in voluntary movements. 3. difficulty in separating the legs during diaper changes. 4. use of only one hand, or both hands, but no the legs.
Treatment for Cerebral Palsy
CP has no cure. Physical, Speech, and Occupational therapy may be helpful. Some research done with stem cells (intravenously)
Prognosis for Cerebral Palsy
If impairment is mild, a near normal life may be possible. If impairment is severe, lifelong care is necessary.
Prevention for Cerebral Palsy
Early prenatal care and good maternal health are only preventative measures known.
Description: birth defect characterized by a hole in the middle of the roof of the mouth. cleft may extend completely through the hard and soft palates into the nasal area. difficulty in sucking and the infant’s facial appearance
Cleft lip and Palate (orofacial clefts)
etilology: Women who smoked before and during pregnancy
Cleft lip and Palate
Diagnostic procedure: formula or milk comes through the nose of the infant
cleft lip and palate
How do you treat cleft lip and palate?
Surgery, speech therapy
Prognosis for cleft lip and palate
good with corrective surgery. Speech therapy may be needed
Prevention of cleft lip and palate
Avoid smoking during pregnancy
