Although the administration of levothyroxine sodium (LT4) to premature infants had been considered safe, several cases of late-onset circulatory collapse (LCC) following the administration of LT4 in very-low-birth-weight (VLBW) infants have been reported in Japan since 2008. This study was performed to investigate the incidence of LCC associated with the administration of LT4 to VLBW infants. ⋯ LT4 is widely used for infants, including VLBW infants, and no major complications have been reported. However, our study revealed that more than a few cases of LCC were associated with the administration of LT4 in VLBW infants. In conclusion, careful attention is necessary when initiating the administration of LT4 to VLBW infants.

Acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) is characterized clinically by biphasic seizures and late magnetic resonance imaging abnormalities, such as reduced subcortical diffusion from day 3 onwards, often accompanied with some neurological sequelae. In the early stages of the disease, AESD closely resembles its far more prevalent and relatively benign counterpart, febrile seizure (FS). ⋯ The combination of CSF S100B and CSF total tau protein resulted in a positive predictive value of AESD 83.3%, which could be helpful for early diagnosis, facilitating early therapeutic interventions.

Comparative Study
Clinical practice guidelines for children with cancer presenting with fever to the emergency room.
Patients with febrile neutropenia (FN) may develop severe infection, septic shock, and death. To improve the outcome of pediatric oncology patients with suspected FN, clinical practice guidelines were developed for these patients at the emergency room (ER). The objective of the present study was to evaluate compliance of the clinical practice guidelines for children with cancer presenting with fever to the ER and adverse outcomes after using the guidelines. ⋯ Using the clinical practice guidelines for pediatric oncology patients with fever was found to reduce the adverse outcomes and improve survival.

Transient tachypnea of the newborn (TTN) is the most common cause of respiratory distress in newborns. Although associated with some morbidity, it is generally believed that once TTN resolves, there is no further increased risk for respiratory disease. However, in limited studies frequency of wheezing attacks is found to be increased in patients who had TTN diagnosis during the newborn period, in comparison to patients who had no respiratory problem. Thus, the question arises as to whether TTN is an innocent disease. ⋯ In conclusion, we established that TTN is an independent risk factor for wheezing. In addition we also hypothesized that genetic and environmental interactions synergistically predisposed these children for future wheezing.

Comparative Study
Serum KL-6 and surfactant protein D in children with 2009 pandemic H1N1 influenza infection.
A global pandemic influenza A (H1N1) outbreak occurred in 2009. Rapid progress of respiratory distress is one of the characteristic features of pandemic influenza A (H1N1) infection. The physiologic mechanism causing hypoxia in pandemic influenza A (H1N1) infection, however, has not been elucidated. ⋯ KL-6 and SP-D elevation were not significant in pandemic influenza A (H1N1) infection associated with chest radiographic abnormality. In pandemic influenza A (H1N1) infection, alveolar involvement was estimated to be little, and severe respiratory distress was probably caused by obstruction of peripheral bronchi.
