Rotavirus infection-associated central nervous system complications: clinicoradiological features and potential mechanisms
Kyung Yeon Lee
Clin Exp Pediatr. 2022;65(10):483-493.   Published online February 7, 2022
∙ Rotavirus infection-associated central nervous system (CNS) complications are fairly common in children.
∙ Common clinicoradiological features include benign convulsions with mild gastroenteritis, acute encephalopathies/encephalitis, cerebellitis, and neonatal rotavirus-associated leukoencephalopathy.
∙ Possible mechanisms for CNS complications include direct viral invasion into the brain via several potential routes such as the blood-brain barrier and vagus nerve, and entry of various brain-damaging mediators and activated immune cells into the brain.

Early myocardial functional abnormalities in primary dyslipidemia: clinical and echocardiographic observations in young children from a highly consanguineous population
Nehal M. El-koofy, Aya M. Fattouh, Areef Ramadan, Mohamed A. Elmonem, Dina H. Hamed
Clin Exp Pediatr. 2022;65(8):410-416.   Published online December 8, 2021
In children with primary dyslipidemia, functional myocardial abnormalities can occur at young age, including diastolic functional impairment of both ventricles and narrowing of the aortic valve and the sinus of Valsalva. Echocardiographic evaluations of high-risk children may be as important as biochemical evaluations.
Nutrition
Impact of preoperative nutritional status on surgical outcomes in patients with pediatric gastrointestinal surgery
Nehal El Koofy, Hadeer Mohamed Nasr Eldin, Wesam Mohamed, Mostafa Gad, Sara Tarek, Gamal El Tagy
Clin Exp Pediatr. 2021;64(9):473-479.   Published online November 16, 2020
Question: Is malnutrition a risk factor for postoperative complications in pediatric surgical patients?
Finding: There is a high incidence of malnutrition in pediatric surgical patients. Stunting increases the risks of postoperative complications and extended hospital stays, while underweight status contributes to extended hospital stays.
Meaning: Preoperative nutritional assessments are crucial to improving postoperative outcomes. Anemia increases the risk of postoperative complications and should be corrected preoperatively.
