· Infantile hemangiomas (IHs) are the most common benign vascular tumors, occurring in 5%–10% of infants.
· IHs are characteristically not present at birth but are usually diagnosed at 1–4 weeks of age, rapidly proliferate until 5 months of age, and then spontaneously involute.
· High-risk IHs (10%) require early treatment from 1 month of age.
· Oral propranolol, a nonselective beta-blocker, is the first-line treatment for IHs.

Human breast milk (HBM) is essential for the infant’s growth and development right after birth and is an irreplaceable source of nutrition for early human survival. Various infant formulas have many similarities to HBM in many components, but there is no perfect substitute for HBM. Recently, various breast milk components and their roles have been studied according to the development...

Question: Potential role of patterns of lung ultrasonography (US) in monitoring changes in mechanically ventilated patients with coronavirus disease 2019 (COVID-19) pneumonia.
Finding: Interstitial syndrome, an irregular pleural line, and peripheral microconsolidation were the most prevalent findings. Changes in lung aeration after mechanical ventilation corelated with improved oxygenation. A fall in lung ultrasound reaeration score ≤ 5 may predict successful weaning.
Meaning: Lung US is gaining wider utility for monitoring COVID-19 pneumonia.

Although the efficacy of montelukast is inferior to that of ICS, both physicians and parents prefer montelukast to ICSs.
EDN may be a useful biomarker for the treatment and monitoring of preschool children with asthma.
The US FDA requires boxed warning about serious neuropsychiatric events of montelukast, therefore, physicians should consider the benefits and risks of montelukast before prescribing it.

∙ The novel coronavirus disease 2019 (COVID-19) was first reported in December 2019 as a cluster outbreak in Wuhan, since then, national lockdowns have included school closures, stay-at-home orders.
∙ The characteristics of adolescent fractures were often related to physical activity such as sports-related injury.
∙ During the COVID-19 pandemic, both in the East and the West, the incidence of fractures in children and adolescents is showing a decreasing trend worldwide.
∙ Fractures in children and adolescents were significantly reduced in the proportion of relatively low-energy damage, and the incidence of fractures in adolescents with greater activity compared to children was reduced.
∙ If COVID-19 pandemic ends, normal academic and sports activities increase due to the easing of lockdown policies, the number of trauma patients related to increased activity may increase rapidly, and clinics should prepare for this change.

· Thrombocytosis, common in newborns and infants (<2 years) (3%–13%), is caused by elevated thrombopoietin (TPO) concentrations.
· Serum TPO levels are significantly higher immediately to 1 month postnatal and decrease with age.
· Platelet counts are positively correlated with gestational age at birth and postnatal age.
· Thrombocytosis is more common in preterm than in term infants.
· Thrombocytosis in newborns is reactive and resolves spontaneously without complications.

Primary caregivers should consider surgical specialist referral of patients with undescended testis if no descent occurs by 6 months, undescended testis is newly diagnosed after 6 months of age, or testicular torsion is suspected. Orchiopexy is recommended between 6 and 18 months at the latest. The original location of the testes and the age at orchiopexy are predictive factors for infertility and malignancy later in life.

-
Osteoporosis diagnosed in children with chronic diseases is a major endocrine complication triggered by the disease itself or its treatment. Although age upon starting osteotoxic agents and the their duration of use are vital contributors, spontaneous recovery of bone mass following treatment completion is a privilege of this specific age group. For any patients short-term glucocorticoid therapy, bone health screening is the next step.

The prevalence of pollen-food allergy syndrome (PFAS) in Korean children with pollen allergy was recently reported to be 42.7%. PFAS can cause a wide range of symptoms from mild allergy to severe anaphylaxis depending on the nature of food allergens that share the epitopes with pollen. Cases of anaphylaxis caused by PFAS have recently increased. Treatments for PFAS should be individualized for patients according to the severity of symptoms.

· Myocarditis was recently examined quantitatively as inflammation of the heart muscle based on endomyocardial biopsy, and its noninvasive diagnosis remains unsatisfactory.
· Additionally, numerous miRNAs (miR-155, miR-146b, miR-590, miR-221, miR-222, etc.) coupled with inflammation or viral activation have been examined in myocarditis patients or mouse models.
· The recent identification of mmu-miR-721 (has-miR-Chr8: 96), a myocarditis-specific microRNA, demonstrated its potential as an acute myocarditis biomarker.

Some neonates, especially those who are premature, may experience hypertension while in the neonatal intensive care unit (NICU). The most common causes are prematurity-related and the hypertension usually resolves over the first 1–2 years of life. Unfortunately, the increasing population of NICU graduates is at risk for later cardiovascular and kidney disease in childhood and adulthood. This population requires careful attention to blood pressure and weight throughout their life course.

· Neonatal seizures are often electrographic-only seizures without clinical signs; therefore, the identification of electrical seizure activity on electroencephalography is the gold standard for diagnosis.
· Clinical signs of neonatal seizures are divided into motor or nonmotor seizures, and motor seizures are mostly focal or multifocal.
· Most neonatal seizures are caused by acute symptomatic etiologies, but in cases of intractable seizures, structural, genetic, or metabolic etiologies should be investigated.

Large-scale quarantine and home confinement during the coronavirus disease 2019 (COVID-19) pandemic will impose new and unfamiliar stressors on children, thereby worsening the childhood obesity epidemic. Physical, nutritional, and psychosocial factors that promote obesity in children during this special situation complementarily contribute to an unprecedented obesogenic environment. Involved stakeholders, including governments, schools, and families, must make all efforts to minimize the impact of the COVID-19 epidemic on childhood obesity.

In the rapidly changing environmental situation during the coronavirus disease 2019 outbreak, neonatal centers have developed telemedicine systems with extended coverage for neonatal monitoring and high-risk follow-up programs including neonatal hyperbilirubinemia. At this point, electronic health technology and noncontact medical system increase the effectiveness of rather than replacing the face-to-face visit and the opinions of experienced neonatologists.
