Clin Exp Pediatr. 2015;58(3):108-111.   Published online March 20, 2015

DiGeorge syndrome is an immunodeficient disease associated with abnormal development of 3rd and 4th pharyngeal pouches. As a hemizygous deletion of chromosome 22q11.2 occurs, various clinical phenotypes are shown with a broad spectrum. Conotruncal cardiac anomalies, hypoplastic thymus, and hypocalcemia are the classic triad of DiGeorge syndrome. As this syndrome is characterized by hypoplastic or aplastic thymus, there are missing...

Fever
Taek Jin Lee, Dong Soo Kim
Clin Exp Pediatr. 2007;50(2):121-126.   Published online February 15, 2007
Fever has been recognized as a cardinal feature of disease since antiquity, but only recently has the pathophysiology of fever come to be understood. It became clear that the ultimate cause of fever is not a bacterial product (a so-called exogenous pyrogen) but a product of host inflammatory cells (i.e., an endogenous pyrogen). Many studies have demonstrated that mononuclear phagocytes...
