Newborns normally regain their birth weight by the time they are 10–14 days old. Consequences of intrauterine estrogen exposure Breast bud development is normal in newborns, Witch Milk independent of sex..

A span of less than six months between pregnancies. * Note: ideal to wait 18 to 24 months between pregnancies. Assisted reproduction e.g. in vitro fertilization. More than one miscarriage or abortion. A previous premature birth. Preeclampsia Placenta previa Prelabor rupture of membrane Characteristics Preterm Term Posture Relaxed attitude, limbs more extended, body size More subcutaneous fat, rests in a more flexed is small, head appear larger in proportion than attitude body Scrotum Undeveloped, not pendulous, minimal rugae Well developed, pendulous, rugated Testes Testes may be in the inguinal canal or in Testes down scrotal sac abdominal cavity Clitoris & labia Prominent, labia majora poorly developed and Fully developed labia majora, clitoris not majora gaping Malaki prominent Scarf sign Elbow may be brough across chest with little or no Resisting attempt to bring elbow past midline resistance Ears Cartilages poorly developed, easily fold Ear cartilages well formed Bend ear3 it doesn't go back Hair Lanugo over back and face Firm hair, separate glands Respiratory Presence of distress, breathing complications Fully developed lungs Brain By 35th weeks baby’s brain still needs to grow 50% higher brain functioning. Body fat Unable to regulate temperature through body fat Has enough fat and energy to regulate body until 34th week function Feeding Weak suck/swallowing; not fully developed till 34th Able to suck, swallow leading to rapid weight weeks gain Cardiac Patent ductus arteriosus If infant is more than 30 weeks, 98% it will close by the time of discharge Central nervous system Poor suck, apneic episode, intraventricular hemorrhage, development of cognitive delays Eyes Retinopathy of prematurity – interfere with the normal vascularization process due to abnormal vessel development and sometimes defects in vision such as blindness Myopia and /or strabismus Gastrointestinal tract Feeding intolerance increasing risk of aspiration Infection Sepsis, meningitis 4x more likely in preterm infant occurring 25% in very low birthweight infants Lungs Pulmonary complications such as respiratory distress syndrome, chronic lung disease Surfactant production is inadequate to prevent alveolar collapse and atelectasis causing respiratory distress syndrome (RDS) * Atelectasis - "Hirap Huminga" long collapse Metabolic problems Hypoglycemia, hyperbilirubinemia Hyperbilirubinemia more common in infant and kernicterus (brain damage caused by hyuperbilirubinemia) occurs even with serum bilirubin is low as 10mg/dL  BRAIN DEVELOPMENT Early stage from embryo to fetus Day 16 – notochord arises from mesoderm which induces the ectoderm to form the neural plate 3rd week – neural plate represents the earliest form of CNS Neural plate rises forming two parallel fold called neural folds resulting in fusion and formation of neural tube Neural tube closes starting from middle Day 25 complete closure of cranial neuropore; day 28 complete closure of caudal neuropore - Fourth week – cranial ends of the neural tube exhibit 3 expansions becoming the primary vesicles: - Proscencephalon - Mesencephalon - Rhombencephalon  BRAIN DEVELOPMENT 5th week – secondary vesicles arise where the primary vesicles further divides into 5 secondary brain vesicles  BRAIN DEVELOPMENT - Prosencephalon or forebrain consists of the diencephalon and the telencephalon. - The diencephalon forms: - thalamus - hypothalamus - third ventricle - choroid plexus - pineal body and neurohypophysis - Interventricular foramina of Monro (allows communication of CSF between lateral ventricle) - The telencephalon forms - cerebral hemispheres - lamina terminalis - Lateral ventricles BRAIN DEVELOPMENT - Mesencephalon is a primary brain vesicle that does not divide further - it forms the midbrain - contains the aqueduct of Sylvius BRAIN DEVELOPMENT - Rhombencephalon or hindbrain consists of the metencephalon and myelencephalon - metencephalon - forms the pons and cerebellum and contains the upper portion of the fourth ventricle - myelencephalon - forms the medulla oblongata and contains the lower portion of the fourth ventricle - alar plates of the metencephalon and myelencephalon, which exist on the dorsal aspect of the neural tube, each consist of three groups of sensory nuclei a. general visceral afferents b. special afferents c. general somatic afferents - basal plates of the metencephalon and myelencephalon (on ventral aspect) for 3 three groups of motor nuclei a. general visceral efferents b. special efferents c. general somatic efferents Congenital Disorders Anencephaly - is the absence of a significant portion of the brain and skull - Due to failure of the neural tube to close between day-23 and day-26 results in the disorder - absence of the scalp, skull and the majority of the brain - usually only the telencephalon is absent Congenital Disorders Exencephaly is a cephalic disorder where the brain is found outside of the skull - absent cranial cavity and scalp with protruding brain tissue - absence of the flat bones of the calvarium and bulging eyeballs - Incompatible with life  Congenital Disorders Cephalocele - protrusion of the meninges and/ or neural tissue through an opening of the skull bones - result from aberrant neural tube development - Craniofacial abnormalities often present in patients with cephaloceles - Meningocele -only the meninges is present outside the skull - pencehalomeningocele including both the meninges and cerebral tissue - encephalocystocele for a ventricular protrusion - gliocele involving a glial-lined cyst with cerebrospinal fluid - All types of cephaloceles lead to development of hydrocephalus, quadriparesis, seizures and severe mental retardation  Congenital Disorders Holoprosencephaly - fetal prosencephalon fails to develop into two cerebral hemispheres develop restricts the division of the cerebral hemispheres - Results in craniofacial abnormalities such as cyclopia which is a midline defect classically typified in a solitary median eye - Clinical signs include varying degrees of craniofacial abnormalities as well as seizures and mental retardation Any Questions?
