==Overview==
==Overview==
The word '[[Jaundice]]' was derived from the French word for [[Yellow discolouration|yellow]] which is '''''jaune'''''. [[Jaundice]] may be [[Classification|classified]] into two broad [[categories]] based on its [[Time series|time]] of onset and [[Causes|cause]] such as [[physiologic]] and [[pathologic]] [[jaundice]]. [[Jaundice]] is [[Causes|caused]] by high [[concentrations]] of [[bilirubin]] in the [[bloodstream]], a [[condition]] known as [[hyperbilirubinemia]]. [[Hyperbilirubinemia]] can [[result]] from [[abnormalities]] in the [[metabolism]] of [[bilirubin]] which could occur at any stage from its [[production]] which is a [[result]] of excessive breakdown of [[red blood cells]], [[Defect|defects]] in its [[hepatic]] [[metabolism]], and its post [[hepatic]] [[Transporter|transport]]. [[Pathologic]] [[causes]] of [[jaundice]] can be [[Classification|classified]] into [[causes]] of [[Conjugated bilirubin|conjugated]] and [[Unconjugated bilirubin|unconjugated]] [[hyperbilirubinemia]]. [[Differentials]] for [[jaundice]] are very limited however, some [[Skin discoloration|skin discolorations]] in [[healthy]] [[Individual growth|individuals]] can look like [[jaundice]] in certain circumstances. The [[prevalence]] of [[jaundice]] varies among [[patient]] [[populations]]. In [[infants]] born at [[term]], 60% will develop [[jaundice]] in their first-week of [[life]] which rises to 80% in [[preterms]]. Common [[risk factors]] in the [[development]] of [[jaundice]] in [[children]] are a [[family history]] of [[jaundice]], [[family history]] of a [[child]] born with [[jaundice]], [[hyperthyroidism]] in mother, [[medication]] use by the mother etc. It is essential for every [[clinician]] to note that [[jaundice]] is not always a [[benign]] condition therefore, extensive [[investigation]] of a [[child]] with [[jaundice]] is necessary to [[prevent]] severe [[complications]]. [[Symptoms]] of [[jaundice]] in [[children]] may include the [[Yellow discolouration|yellowish discoloration]] of [[skin]], [[sclera]], and [[mucous membrane]]. A useful [[technique]] in assessing the severity of [[jaundice]] is by using the [[principle]] of [[skin discoloration]] progressing in a cephalo-caudal direction in [[newborns]]. [[Laboratory]] findings include measuring the [[serum bilirubin]] from a [[blood]] sample. The total and [[Conjugated bilirubin|conjugated]] portions are measured and the [[Unconjugated bilirubin|unconjugated fraction]] is measured by subtracting the [[Conjugated bilirubin|conjugated fraction]] from the total. [[Echocardiography]] can detect [[cardiac]] [[abnormalities]] in [[patients]] with [[Alagille syndrome]] and [[biliary atresia]]. [[Ultrasonography]] of the [[abdomen]] is used to [[screen]] for [[biliary atresia]], [[choledochal cysts]], or [[cholestatic]] workup in the setting of [[Conjugated bilirubin|conjugated]] [[hyperbilirubinemia]]. [[Treatment]] options include [[phototherapy]], [[intravenous]] [[immunoglobulin]] ([[IVIG]]), and [[exchange transfusion]]. [[Pharmacological]] options are also there. [[Surgery]] is the mainstay of [[therapy]] or the definitive [[treatment]] for most [[obstructive]] [[causes]] of [[Conjugated bilirubin|conjugated]] [[hyperbilirubinemia]]. Several [[etiologies]] may be generally difficult to [[prevent]] however, the [[prevention]] of [[complications]] from [[jaundice]] is equally crucial. Parents should be educated on how to recognize [[jaundice]] very early in a [[neonate]] so as to present promptly for the management.

Overview

The word 'Jaundice' is derived from the French word for yellow, which is jaune. Jaundice may be classified into two broad categories based on its time of onset and cause such as physiologic and pathologic jaundice. Jaundice is caused by high concentrations of bilirubin in the bloodstream, a condition known as hyperbilirubinemia. Hyperbilirubinemia can result from abnormalities in the metabolism of bilirubin which could occur at any stage from its production, which is a result of the excessive breakdown of red blood cells, defects in its hepatic metabolism, and its post hepatic transport. Pathologic causes of jaundice can be classified into causes of conjugated and unconjugated hyperbilirubinemia. Differentials for jaundice are very limited however, some skin discolorations in healthy individuals can look like jaundice in certain circumstances. The prevalence of jaundice varies among patient populations. In infants born at term, 60% will develop jaundice in their first-week of life, which rises to 80% in preterms. Common risk factors in the development of jaundice in children are a family history of jaundice, family history of a child born with jaundice, hyperthyroidism in the mother, medication use by the mother, etc. It is essential for every clinician to note that jaundice is not always a benign condition therefore, extensive investigation of a child with jaundice is necessary to prevent severe complications. Symptoms of jaundice in children may include the yellowish discoloration of skin, sclera, and mucous membrane. A useful technique in assessing the severity of jaundice is by using the principle of skin discoloration progressing in a cephalo-caudal direction in newborns. Laboratory findings include measuring the serum bilirubin from a blood sample. The total and conjugated portions are measured and the unconjugated fraction is measured by subtracting the conjugated fraction from the total. Echocardiography can detect cardiac abnormalities in patients with Alagille syndrome and biliary atresia. Ultrasonography of the abdomen is used to screen for biliary atresia, choledochal cysts, or cholestatic workup in the setting of conjugated hyperbilirubinemia. Treatment options include phototherapy, intravenous immunoglobulin (IVIG), and exchange transfusion. Pharmacological options are also there. Surgery is the mainstay of therapy or the definitive treatment for most obstructive causes of conjugated hyperbilirubinemia. Several etiologies may be generally difficult to prevent however, the prevention of complications from jaundice is equally crucial. Parents should be educated on how to recognize jaundice very early in a neonate so as to present promptly for the management.
