Study Notes
Neonatal Period
- Defined as the time from birth to the 28th day of life.
- Subdivided into very early (birth-24 hours), early (1-7 days), and late (8-28 days) neonatal periods.
- Highest mortality rates occur during the first 24 hours post-birth.
- Major causes of mortality include prematurity, low birth weight, and congenital anomalies.
Neonatal Mortality Rate
- Calculated as the number of neonatal deaths in a year divided by the number of live births that year.
- Neonatal deaths account for 37% of all childhood deaths under 5 years old.
High-Risk Pregnancy
- 10-20% of pregnant women are classified as high-risk, indicating a greater likelihood of poor outcomes.
- Associated factors include genetic and maternal conditions.
Neural Tube Defects (NTDs)
- Refers to abnormalities resulting from failure of the neural tube to close, typically between the 3rd and 4th week of gestation.
- Folic Acid supplementation is crucial, especially if a previous NTD was noted.
Types of Neural Tube Defects
-
Spina Bifida Occulta: A mild form without protrusion of the spinal cord; may have asymptomatic patients with cutaneous signs.
- Diagnosis through ultrasound (UTZ) and MRI.
-
Meningocele: Meninges herniate through bony defects, typically with a fluctuating mass that may transilluminate.
- Requires thorough diagnostics prior to surgery.
-
Myelomeningocele: Most severe form with both spinal cord and meninges herniating through vertebral defects.
- Clinical manifestations include organ dysfunction and incontinence, with potential for hydrocephalus.
Prognosis and Treatment of NTDs
- Management involves a multidisciplinary approach with evaluation for other congenital anomalies.
- Renal dysfunction is the most critical factor influencing mortality.
Anencephaly
- Condition characterized by a large defect in the skull and absence of major brain structures (cerebrum and cerebellum).
- Infants typically die within days of birth.
Microcephaly
- Defined as head circumference 3 SD below the mean for age and sex.
- Diagnosed based on head circumference measurements, MRI for structural analysis, and TORCH assay.
- Treatment includes family counseling and referral to specialists.
Hydrocephalus
- Involves abnormal accumulation of cerebrospinal fluid within the ventricular system.
- Symptoms depend on age, nature of the lesion, and duration of intracranial pressure increase.
- Management includes identifying the underlying cause and possibly VP shunting.
Neonatal Infections
- Significant contributor to neonatal morbidity and mortality due to diverse transmission modes, immunologic immaturity, and coexisting conditions.
High-Risk Infants
- Infants needing close monitoring to reduce morbidity and mortality, potentially comprising 10-20% of births.
- Categories include multiple gestation pregnancies, premature infants, small for gestational age (SGA), intrauterine growth restriction (IUGR), and post-term infants.
