Sickle Cell Anemia Description
Hereditary, chronic anemia
Sickle or crescent-shaped RBC. Impairs circulation, damage blood vessels, produce organ damage. Most prevalent among those w/ African descent.
Sickle Cell Anemia Etiology
Presence of abnormal form of hemoglobin (Hemoglobin S).
Sickle Cell trait
One Hemoglobin S gene
Sickle Cell Anemia
Two copies of Hemoglobin S genes
Sickle Cell Anemia Signs/Symptoms
Acute
Episodic attacks of intense pain (crises) in arms, legs, or abdomen, fever Chronic: Jaundice, chronic fatigue, dyspnea, tachycardia, pallor.
Infections, stress, and extreme temperatures may trigger a crises.
Sickle Cell Anemia Chronic Sx
Jaundice, chronic fatigue, dyspnea, tachycardia, pallor.
Infections, stress, and extreme temperatures may trigger a crises.
Sickle Cell Anemia Chronic Sx
Chronic: Jaundice, chronic fatigue, dyspnea, tachycardia, pallor.
Infections, stress, and extreme temperatures may trigger a crises.
Sickle Cell Anemia Chronic Sx
Jaundice, chronic fatigue, dyspnea, tachycardia, pallor.
Infections, stress, and extreme temperatures may trigger a crises.
Sickle Cell Anemia Diagnostic Procedures
Infant Screening for at-risk patients. Low hematocrit and sickled cells on blood smear.
Treatment
Symptomatic treatment including analgesics and hydration. Folate replacement.
Blood transfusions, bone marrow transplant.
Prognosis
Variable depending on the degree of severity. Life-threatening disease, with life expectancy into middle age.
Prevention
None.
Symptomatic prevention includes healthy diet, folic acid supplement, proper hydration, avoid extreme temperatures, moderate exercise and adequate rest.

Neural Tube Defects Description
Include spina bifida, meningocele, myelomeningocele (see p. 117). Develop in the 1st month of pregnancy. Incomplete closure of the bones encasing the spinal cord.
Neural Tube Defects Etiology
Expected closure of neural tube between day 20-23 of gestation.
Cause of lack of closure unknown. Research supports the lack of folic acid as a cause.
Neural Tube Defects Signs/Sx
Symptoms range from dimple, hair tuft, nevus to foot weakness, bowel/bladder dysfunction, sac-like protrusion, partial paralysis, club foot, Chiari malformation
Neural Tube Defects Diagnostic Procedures
Prenatal evaluation through ultrasound between 14-16 weeks. Aminocentesis.
After birth physical exam, x-ray, sensory and motor exam
Neural Tube Defects Treatment
No cure. Treatment ranges from none to surgical repair and supportive measures.
Neural Tube Defects Prognosis
Dependent on extent of neurological deficit. Spina bifida has the best prognosis
Neural Tube Defects Prevention
Folic acid during pregnancy
Hydrocephalus Description
Too much cerebrospinal fluid (CSF) in the ventricles of the brain.
Etiology
Genetic defect or developmental disorder associated with the neural tube. Trauma, specific infections
Signs/symptoms
Symptoms vary. Enlarged head (infant), high-pitched cries, abnormal muscle tone in their legs. Projectile vomiting, irritability, sleepy. Older children: headache, nausea, vomiting, blurred vision, problems with balance, coordination, and walking.

Hydrocephalus Signs/Sx
Symptoms vary. Enlarged head (infant), high-pitched cries, abnormal muscle tone in their legs. Projectile vomiting, irritability, sleepy. Older children: headache, nausea, vomiting, blurred vision, problems with balance, coordination, and walking.
Hydrocephalus Diagnostic Procedures
Neurological assessment and physical exam. Ultrasound, MRI, CT
Treatment
Surgical correction. Shunt fluid away from the ventricles to the abdomen.
Prognosis
Guarded. Expect both cognitive and physical developmental difficulties, vision loss, impaired motor function.
