Reynolds' pentad is a collection of signs and symptoms consistent with obstructive ascending cholangitis, a serious infection of the biliary tract.It is a combination of Charcot's triad (right upper quadrant pain, jaundice, and fever) with shock (low blood pressure, tachycardia) and an altered mental status.

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
Rotor type hyperbilirubinemia is a distinct yet similar disorder to Dubin–Johnson syndrome [1] – both diseases cause an increase in conjugated bilirubin, but Rotor syndrome differs in that it is a result of impaired hepatocellular storage of conjugated bilirubin that leaks into plasma causing hyperbilirubinemia.
Van den Bergh reaction is a chemical reaction used to measure bilirubin levels in blood. [1] [2] More specifically, it determines the amount of conjugated bilirubin in the blood.
Hyperbilirubinemia may be observed when hemolysis produces too much bilirubin through the excessive breakdown of red blood cells, and the bilirubin builds up in the patient's blood and tissue fluids without proper excretion. [43] Untreated or inadequately treated hyperbilirubinemia will lead to other complications such as kernicterus. [12]
Kernicterus is a bilirubin-induced brain dysfunction. [1] The term was coined in 1904 by Christian Georg Schmorl.Bilirubin is a naturally occurring substance in the body of humans and many other animals, but it is neurotoxic when its concentration in the blood is too high, a condition known as hyperbilirubinemia.
Pica in dogs may be a sign of immune-mediated hemolytic anemia, especially when it involves eating substances such as tile grout, concrete dust, and sand. Dogs exhibiting this form of pica should be tested for anemia with a complete blood count including hematocrit levels, or packed cell volume. [46] [47]
The syndrome cannot cause severe indirect hyperbilirubinemia in neonates by itself, but it may have a summative effect on rising bilirubin when combined with other factors, [10] for example in the presence of increased red blood cell destruction due to diseases such as G6PD deficiency.
