Omalizumab is effective in children with severe asthma, but its impact on medical cost in Japan is not clear. We evaluated the impact of omalizumab on medical cost by comparing the pre- vs post-omalizumab-initiation medical costs of 12 children with severe asthma who received omalizumab for 2 years, and calculating incremental cost-effectiveness ratio for omalizumab therapy. Health outcome was measured as hospital-free days (HFD). ⋯ Omalizumab led to an estimated increase of 40.8 HFD per omalizumab responder patient per 2 years. The cost was JPY 20 868 per additional HFD. Omalizumab can therefore reduce hospitalization cost in children with severe asthma in Japan.

Case Reports
Incomplete Kawasaki disease in a 12-month-old girl presenting with cardiac murmur and iron deficiency anemia.
Kawasaki disease (KD) is an acute necrotizing vasculitis that occurs in children <5 years of age. The cause of KD remains unknown, but various complications, including dilatation of the coronary arteries, can occur. Coronary artery aneurysm or ectasia are the most important complications of KD. ⋯ Meanwhile, iron deficiency anemia (IDA) is one of the most prevalent micronutrient deficiencies in the world. Children with IDA are prone to infection and inflammation. We report the case of a 12-month-old girl with incomplete KD who presented with cardiac murmur and severe IDA.

Multicenter Study
Use of high-flow nasal cannula in neonates: Nationwide survey in Japan.
High-flow nasal cannula is a new modality of respiratory support and is increasing in popularity despite the lack of supporting evidence. We investigated the prevalence of its use in tertiary neonatal units in Japan. A paper-based survey was conducted. ⋯ The main perceived benefits of the cannula included better access to the neonate and reduced risk of nasal trauma. This survey found that high-flow nasal cannula is used without clear criteria and that clinical practice varies across neonatal units in Japan. Its use in neonates needs to be urgently evaluated.

There is a paucity of data on lung physiology in late-preterm children, who may be exposed to a risk of decline in lung function during childhood. In this study, we evaluated lung function in preschool children born late preterm using impulse oscillometry (IOS), and compared the results with those obtained in healthy term-born children. ⋯ Children born late preterm had signs of peripheral airway obstruction on IOS-based comparison with healthy term-born controls. Besides the inherent disadvantages of premature birth, hospitalization for pulmonary infection and passive smoking also seemed to adversely affect lung function in children born late preterm.

The aim of this study was to evaluate the diagnostic value of red blood cell distribution width (RDW) in children with acute appendicitis. ⋯ Children with histologically proven acute appendicitis have higher RDW than children without appendicitis, but the diagnostic value of RDW was not superior to WBC or CRP in children with acute appendicitis. Although higher RDW may be valuable for aiding the diagnosis of acute appendicitis in children, it is not a useful marker for predicting perforated appendicitis.
