Choanal atresia is caused by problems with the development of the nasal cavity and the palate. Development begins with neural crest cells. Frontonasal processes fold, forming nasal placodes (nasal pits). The nasobuccal membrane must rupture in places to form the choanae. A number of theories exist as to how this developmental process causes ...
Infant respiratory distress syndrome (IRDS), also known as surfactant deficiency disorder (SDD), [2] and previously called hyaline membrane disease (HMD), is a syndrome in premature infants caused by developmental insufficiency of pulmonary surfactant production and structural immaturity in the lungs.
Newborns typically consume half an ounce for the first 2 days after birth but will gradually increase to 1 or 3 ounces until 2 weeks after birth. They will begin to drink 2 to 3 ounces. One should expect to feed the baby every 8 to 12 times per day in a 24 hours span.
[3] This is referred to as "obligate nasal breathing." [4] Nasal congestion can interfere with hearing and speech. Significant congestion may interfere with sleep, cause snoring, and can be associated with sleep apnea or upper airway resistance syndrome. [5] In children, nasal congestion from enlarged adenoids has caused chronic sleep apnea ...
The face of a newborn infant displaying snuffles indicative of congenital syphilis "Hereditary" syphilis: radiating fissures of the lips (1916). Newborns may be asymptomatic and are only identified on routine prenatal screening. If not identified and treated, these newborns develop poor feeding and runny nose. [17]
If the neonate (a newborn less than 4 weeks of age) [5] is expected to have NAS, they may need to stay in the hospital to be monitored for a week. A baby born at full-term may commonly exhibit symptoms such as mottling (net-like bluish-red skin due to swollen blood vessels), [6] irritability, trembling, excessive or high-pitched crying ...
Transient tachypnea of the newborn occurs in approximately 1 in 100 preterm infants and 3.6–5.7 per 1000 term infants. It is most common in infants born by caesarian section without a trial of labor after 35 weeks of gestation. Male infants and infants with an umbilical cord prolapse or perinatal asphyxia are at higher risk
Meconium induces an inflammatory reaction within the lungs as there is an increase of autophagocytic cells and levels of caspase 3 after exposure. After 8 hours of meconium exposure, in rabbit foetuses, the total amount of apoptotic cells is 54%. [15] Therefore, the majority of meconium-induced lung damage may be due to the apoptosis of lung ...
