Respiratory function testing for guiding ventilator mode conversion in congenital diaphragmatic hernia.

Introduction: For patients with a congenital diaphragmatic hernia, conventional mechanical ventilation (CMV) and high-frequency oscillatory ventilation (HFOV) are used in initial ventilatory management. HFOV has recently been recommended as a rescue therapy; however, we use HFOV for initial ventilation management, with a preoperative challenge test for CMV conversion and respiratory function testing at the time of CMV conversion. We aimed to compare patient characteristics between CMV conversion- and HFOV-preferred treatment groups.

Using airway resistance measurement to determine when to switch ventilator modes in congenital diaphragmatic hernia: a case report.

Background: Congenital diaphragmatic hernia is a deficiency of the fetal diaphragm resulting in herniation of the abdominal viscera into the thoracic cavity. The best method of respiratory management of congenital diaphragmatic hernia is unclear, but high frequency oscillatory ventilation is often used as the initial ventilator mode for severe congenital diaphragmatic hernia. When it becomes impossible to maintain the pre-ductal saturations, the timing of successful switching of the ventilation mode from high frequency oscillatory ventilation to conventional mechanical ventilation remains unclear.

Temporal Relationship between Serum Levels of Interleukin-6 and C-Reactive Protein in Therapeutic Hypothermia for Neonatal Hypoxic-Ischemic Encephalopathy.

 C-reactive protein (CRP) is a useful marker of neonatal infection. Recent studies have shown that neonatal therapeutic hypothermia delays an elevation of CRP in infants with hypoxic-ischemic encephalopathy (HIE). This study investigated the time difference of peak levels of serum CRP and other inflammatory responses during therapeutic hypothermia.

Tailor-made circulatory management based on the stress-velocity relationship in preterm infants.

Preterm infants frequently experience pulmonary hemorrhage or cerebral intraventricular hemorrhage after birth. The immature myocardium of the left ventricle faces a high afterload after the baby is separated from the placenta. However, the preterm left ventricle has limited ability to respond to such an increase in afterload.

TSH suppression after intravenous glucocorticosteroid administration in preterm infants.

Background: Reports have described that, in adults, steroids suppress thyroid-stimulating hormone (TSH) and triiodothyronine (T3) and might suppress thyroxine (T4). No data have been reported for thyroid hormone changes before or after administration of glucocorticoid in preterm infants.

Aims: The aim of this study was to investigate short-term effects of thyroid hormones on preterm infants.

Magnetic resonance imaging regional T1 abnormalities at term accurately predict motor outcome in preterm infants.

Objective: The aim of this study was to assess whether periventricular leukomalacia findings are sufficiently sensitive for predicting the severity of motor prognosis by conventional MRI in the near term.

Methods: Preterm infants with T1 hyperintensity or cysts in the periventricular regions on term MRI were selected, and their gross motor functions were evaluated at the age of 3 to 5 years. Sixty-two infants had findings of T1 hyperintensity or cysts, and except for infants with these findings, none were diagnosed later as periventricular leukomalacia.

Congenital neuroblastoma in a patient with partial trisomy of 2p.

We report the fourth example of a patient with germline partial trisomy of 2p21-pter and congenital neuroblastoma. The male infant had a dysmorphic facial expression and presented with congenital heart disease, supernumerary nipples, hypospadias, shawl scrotum, hemilateral persistent hyperplastic primary vitreous, and neuroblastoma. His germline karyotype of 46,XY,der(8)t(2;8)(p21;p23.
