Serum sickness in humans is a reaction to proteins in antiserum derived from a non-human animal source, occurring 5–10 days after exposure. Symptoms often include a rash , joint pain , fever , and lymphadenopathy .
Jaundice in infants, as in adults, is characterized by increased bilirubin levels (infants: total serum bilirubin greater than 5 mg/dL). Normal physiological neonatal jaundice is due to immaturity of liver enzymes involved in bilirubin metabolism, immature gut microbiota, and increased breakdown of fetal hemoglobin (HbF). [ 54 ]
In 1906, Clemens Pirquet and Béla Schick described serum sickness in children receiving large quantities of horse-derived antitoxin. [52] Between 1910 and 1911, Béla Schick developed the Schick test to detect pre-existing immunity to diphtheria in an exposed person. Only those who had not been exposed to diphtheria were vaccinated.
Laboratory abnormalities include normal or mild decreases in serum C3, C4, and CH50 levels, and mild proteinuria. In contrast to true serum sickness, renal and hepatic involvement is rare. Significant decreases in serum C3, C4, and CH50, reported in the literature for true serum sickness, are rarely described in serum sickness–like reaction.
Since the syndrome is due to the accumulation of chloramphenicol, the signs and symptoms are dose related. [10] According to Kasten's review published in the Mayo Clinic Proceedings, a serum concentration of more than 50 μg/mL is a warning sign, [10] while Hammett-Stabler and John states that the common therapeutics peak level is 10-20 μg/mL and is expected to achieve after 0.5-1.5 hours of ...
Children between the ages of 2-12 are more prone to experiencing motion sickness than adults, per Cleveland Clinic. Adults over the age of 50 are less susceptible to motion sickness, according to ...
Liver dysfunction (only applicable to infants > 1 month) total serum bilirubin ≥ 4 mg/dL, or; alanine aminotransferase (ALT) ≥ 2 times the upper limit of normal; Consensus definitions, however, continue to evolve, with the latest expanding the list of signs and symptoms of sepsis to reflect clinical bedside experience.

Bronze baby syndrome (dark pigmentation of skin). The primary symptom is yellowish discoloration of the white part of the eyes and skin in a newborn baby. [1] Other symptoms may include excess sleepiness or poor feeding. [1] A bilirubin level more than 34 μmol/L (2 mg/dL) may be visible. [1]
