Question: Is the tumor necrosis factor (TNF) signaling pathway (TNF-α-converting enzyme [TACE]/TNF-α/angiotensin converting enzyme [ACE]) involved in pediatric coronavirus disease 2019 (COVID-19) infection?
Finding: Significantly increased circulating TACE/TNF-α and decreased ACE2 levels were noted. TNF-α-308G/A plays a significant role in susceptibility to COVID-19 infection among children. The ACE (I/D) (rs4646994) and ACE2 (rs2285666) single nucleotide polymorphisms lack significant associations with pediatric COVID-19 infection.
Meaning: The TNF signaling pathway participates in pediatric COVID-19 infection.

· Systemic autoinflammatory disorders (SAID) are disorders caused by dysregulation of the innate immunity with genetic background, leading to recurrent episodes of systemic inflammation.
· SAID is characterized by recurrent acute inflammatory responses including fever or skin manifestations, unrelated with infection or malignancy.
· Diagnosis is based on family and long-term history with detailed clinical and laboratory manifestations during febrile periods.

Timely diagnosis of hyponatremia is important for preventing potential morbidity and mortality as it is often an indicator of underlying disease. The most common cause of eurvolemic hyponatremia is the syndrome of inappropriate antidiuretic hormone (SIADH) secretion. Recent studies have demonstrated that proinflammatory cytokines such as interleukin (IL) 1β and IL-6 are involved in the development of hyponatremia, a condition...

Case Report

Two adolescent cases of Fitz-Hugh-Curtis syndrome

Ji Hye Kim, Sung Hee Oh

Clin Exp Pediatr. 2009;52(9):1038-1043. Published online September 15, 2009

Two adolescent cases of Fitz-Hugh-Curtis syndrome, which has not been previously reported in Korean girls, presenting with right upper-quadrant abdominal pain, nausea, vomiting, and fever are reported here. A careful and thorough inquiry into the sexual history of the first patient, which was not done upon admission, led to a careful reassessment of the dynamic abdominal computed tomography scan revealing...
