- Kidney complications associated with COVID-19 infection and vaccination in children and adolescents: a brief review
- Hee Sun Baek, Min Hyun Cho
- Clin Exp Pediatr. 2023;66(10):424-431. Published online June 28, 2023
-
Several observational studies have shown that acute kidney injury affects up to 46% of children and adolescents who develop severe postinflammatory responses, such as multisystem inflammatory syndrome in childhood, due to coronavirus disease 2019 (COVID-19). Although causality has not been established, some cases of glomerulopathy or nephrotic syndrome occurring after COVID-19 infection or vaccination have been reported. Therefore, kidney complications associated with these conditions in children and adolescents warrant attention.

- Predictors of high-flow nasal cannula failure in pediatric patients with acute respiratory distress
- Kantara Saelim, Busawan Thirapaleka, Kanokpan Ruangnapa, Pharsai Prasertsan, Wanaporn Anuntaseree

-
SpO2/FiO2 ratio ≤166, pediatric respiratory rate-oxygenation index <132, and clinical respiratory score ≥6 at 12 hours after high-flow nasal cannula (HFNC) initiation were useful bedside predictors for HFNC failure in pediatric patients.

- Febrile urinary tract infection in children: changes in epidemiology, etiology, and antibiotic resistance patterns over a decade
- Woosuck Suh, Bi Na Kim, Hyun Mi Kang, Eun Ae Yang, Jung-Woo Rhim, Kyung-Yil Lee
- Clin Exp Pediatr. 2021;64(6):293-300. Published online October 14, 2020
-
Question: How has the antibiotic susceptibility of urinary pathogens changed and what does it imply?
Finding: A yearly increase in multidrug-resistant and extended-spectrum β-lactamase (ESBL)–producing pathogens was observed. A higher recurrence rate was observed in cases of febrile urinary tract infection caused by ESBL producers in patients with underlying vesicoureteral reflux (VUR).
Meaning: The initial empirical antibiotic should reflect the changing susceptibility patterns and underlying VUR status.

MOG antibody-associated disorder exhibits different pathophysiological and phenotypic findings than both aquaporin-4 antibody-associated neuromyelitis optica spectrum disorder and typical MS. MOG-antibody is of particular interest in pediatric patients with clinical or radiological non-MS typical findings. MOG-antibody was included in a diagnostic algorithm for children recommending for the first time a standardized use in clinical practice except in cases of typical MS.

- Variation in clinical usefulness of biomarkers of acute kidney injury in young children undergoing cardiac surgery
- Hee Sun Baek, Youngok Lee, Hea Min Jang, Joonyong Cho, Myung Chul Hyun, Yeo Hyang Kim, Su-Kyeong Hwang, Min Hyun Cho

-
Question: Can clinical usefulness of biomarkers of acute kidney injury vary on the clinical circumstances?
Finding: In young children undergoing cardiac surgery, urine KIM-1/Cr level peaked at 24 hours with significant difference from baseline level and was significantly higher at 6 hours in the AKI group. However, urine NGAL/Cr and IL-18/Cr levels showed no specific trend with time for 48 hours after cardiac surgery.
Meaning: Urine KIM-1/Cr concentration could be considered a good biomarker for early AKI prediction after open cardiac surgery in young children.

Acute kidney injury (AKI) is characterized by abrupt deterioration of renal function, and its diagnosis relies on creatinine measurements and urine output. AKI is associated with higher morbidity and mortality, and is a risk factor for development of chronic kidney disease. There is no proven medication for AKI. Therefore, prevention and early detection are important. Physicians should be aware of...

Since the successful introduction of all-trans-retinoic acid (ATRA) and its combination with anthracycline-containing chemotherapy, the prognosis for acute promyelocytic leukemia (APL) has markedly improved. With ATRA and anthracycline-based-chemotherapy, the complete remission rate is greater than 90%, and the long-term survival rate is 70-89%. Moreover, arsenic trioxide (ATO), which was introduced for APL treatment in 1994, resulted in excellent remission rates...
