Introduction: The effects of hydrocortisone (HDC) administration to extremely low birth weight (ELBW) infants on later development remain unclear. This study examined the association between HDC dosage during neonatal period and neurodevelopmental outcomes in ELBW infants. Methods: This study was a retrospective cohort study conducted in eight centers in Japan. The subjects of this study were ELBW infants born between April 2015 and March 2017. The association between postnatal total HDC dosage up to 36 weeks postmenstrual age and the developmental quotient (DQ) at 3 years of age was examined. Multiple linear regression evaluated the association, adjusting for weeks of gestation, birth weight, and the presence of bronchopulmonary dysplasia, late-onset circulatory collapse, intracranial hemorrhage, necrotizing enterocolitis, and sepsis. Results: This study included 218 ELBW infants, of whom 144 underwent a developmental test at 3 years of age. Simple linear regression analysis revealed a significant association between total HDC dosage and DQ at 3 years of age (coefficients: −2.65, 95% CI: −3.73, −1.57). Multiple linear regression analysis adjusted for the presence of bronchopulmonary dysplasia and late-onset circulatory collapse also revealed a significant association between total HDC dosage and DQ at 3 years of age (coefficients: −2.66, 95% CI: −3.89, −1.42). Conclusion: Higher total HDC dosage up to 36 weeks postmenstrual age in ELBW infants was associated with impaired neurodevelopmental outcomes. Although HDC is often needed in the treatment of ELBW infants, clinicians should be aware that an increased dose of HDC may be associated with impaired neurodevelopmental outcomes.

The patient was a boy born at 23 weeks and 0 days of gestation weighed 401 g at birth. For treatment, an umbilical venous catheter was placed but the catheter perforated a blood vessel. We thought that prompt removal of the catheter would lead to massive bleeding, so we kept the catheter in place at the umbilicus, waited for weight gain, and removed it after confirming that the catheter tip had spontaneously become shallow and was in the umbilical vein. This procedure allowed us to handle the patient without major problems.

The aim of this study is to investigate whether it is possible to detect future behavioral and emotional problems in extremely low-birth-weight infants by evaluating the neonatal head magnetic resonance imaging (MRI) using a scoring system. This study included 62 extremely low-birth-weight infants born between April 2015 and March 2017 and those who had undergone MRI at 36 to 42 weeks of gestation. These subjects were administered with the Strength and Difficulties Questionnaire (SDQ) at age 4–5, and the patients who responded to the questionnaire were included in the study. A positive correlation was observed between the Global Brain Abnormality Score and Total Difficulties Score of the SDQ (r = 0.26, p = 0.038). However, no significant difference was observed between the median Global Brain Abnormality Score of the normal and borderline-range group and the Total Difficulties Score of the clinical-range group (p = 0.51). This study demonstrated the relationship between the MRI findings in the newborn period and the emotional and behavioral problems in early childhood, but it is not clinically useful as a predictive marker.

Human metapneumovirus (HMPV) and respiratory syncytial virus (RSV) are the leading causes of acute respiratory tract infection in children, and clinical manifestations of these virus infections are considered similar. To investigate the differences in clinical characteristics between HMPV and RSV infections in young children, we prospectively enrolled children ＜ 3 years old who required hospitalization with acute respiratory tract infection due to HMPV or RSV at 10 hospitals in Japan. We enrolled 48 children with HMPV infection and 141 with RSV infection. Patients with HMPV infection were older than those with RSV infection. High-grade fever was more frequently observed in patients with HMPV infection, whereas no significant differences in respiratory symptoms were apparent. Abnormal serum lactate dehydrogenase values and consolidation shadows on chest X-ray were more frequently observed in patients with HMPV infection. During hospitalization, nasal mucus suction was more frequently required in patients with RSV infection. On the other hand, β2-adrenergic agonists, corticosteroids, and leukotriene receptor antagonists were more frequently used in patients with HMPV infection. These findings suggest that HMPV and RSV infections show similar respiratory symptoms, but HMPV infection is more likely to lead to the development of pneumonia, at least among hospitalized young children.
