Physiologic jaundice can be a benign condition that presents in newborns until two weeks of life. [2] However, jaundice that continues after two weeks requires follow up with measurement of total and conjugated bilirubin. [3] Elevated levels of conjugated bilirubin are never benign and require further evaluation for neonatal cholestasis. [3]
Neonatal jaundice; Other names: Neonatal hyperbilirubinemia, neonatal icterus, jaundice in newborns: Jaundice in a newborn: Specialty: Pediatrics: Symptoms: Yellowish discoloration of the skin and white part of the eyes [1] Complications: Seizures, cerebral palsy, kernicterus [1] Usual onset: Newborns [1] Types: Physiologic, pathologic [1] Causes
Jaundice is commonly associated with severity of disease with an incidence of up to 40% of patients requiring intensive care in ICU experiencing jaundice. [48] The causes of jaundice in the intensive care setting is both due to jaundice as the primary reason for ICU stay or as a morbidity to an underlying disease (i.e. sepsis). [48]
Pathological jaundice in newborns should be suspected when the serum bilirubin level rises by more than 5 mg/dL per day, serum bilirubin more than the physiological range, clinical jaundice more than 2 weeks, and conjugated bilirubin (dark urine staining clothes). Haemolytic jaundice is the commonest cause of pathological jaundice.
The infant with neonatal hepatitis usually has jaundice that appears at one to two months of age, is not gaining weight and growing normally, and has an enlarged liver and spleen. Infants with this condition are usually jaundiced. Jaundice that is caused by neonatal hepatitis is not the same as physiologic neonatal jaundice. In contrast with ...
Most neonates with congenital CMV infection will not have any symptoms, but a minority of infected newborns will have symptomatic infection. Common symptoms include rash, microcephaly (small head), low birth weight, jaundice, thrombocytopenia, seizures and retinitis.
Isoimmunization occurs when the maternal immune system is sensitized to red blood cell surface antigens. The most common causes of isoimmunization are blood transfusion, and fetal-maternal hemorrhage. [12] The hemolytic process can result in anemia, hyperbilirubinemia, neonatal thrombocytopenia, and neonatal neutropenia. [6]
However, infants with biliary atresia develop progressive conjugated jaundice, pale white stools, and dark urine. Some infants fail to thrive as there will be a degree of fat and fat-soluble vitamin malabsorption (e.g. Vitamin K). This may cause a bleeding tendency. Eventually, and usually after 2 months, cirrhosis with portal hypertension will ...
