We present the case of a fetus with cardiac capillary hemangioma in the right atrial cavity. The tumor showed dramatic growth between the 28th and 32nd week of gestation and resulted in tachyarrhythmia. The patient was born at the 33 weeks of gestation weighing 2430 g via urgent cesarean section because the rapidly growing cardiac tumor caused incessant tachyarrhythmia, pericardial effusion, and fetal circulatory incompetence. Coronary angiography revealed that the right coronary artery drained into the tumor. Due to hemodynamic deterioration, the patient underwent subtotal resection of the tumor on the 2nd day after birth. Histopathological examination revealed an undifferentiated capillary hemangioma. The patient was discharged at the age of 86 days, as the tachyarrhythmia and hemodynamic incompetence had subsided; however, bradycardia and intermittent atrioventricular conduction disturbance gradually developed. Capillary hemangioma, a rare primary cardiac space‐occupying tumor in children, can invade the conduction system. [ABSTRACT FROM AUTHOR]

Many studies have reported acute encephalopathy with biphasic seizures and late reduced diffusion ( AESD) associated with viral infection at onset, but few studies have reported AESD without infection. We report the case of a 9-month-old boy who had a clinical course mimicking AESD after a traffic accident. The traffic accident caused a mild subdural hematoma without neurological abnormalities on admission. The boy became unconscious on the second day, and he was diagnosed with non-convulsive status epilepticus on the third day. Diffusion-weighted imaging showed reduced water diffusion in the subcortical white matter. On laboratory analysis interleukin ( IL)-6 was elevated in the cerebrospinal fluid ( CSF), but not in the serum. He had severe neurological sequelae with mental retardation, spastic tetraplegia, and epilepsy. We suggest that brain damage mimicking AESD was caused by the traffic accident and the prolonged seizure during infancy. [ABSTRACT FROM AUTHOR]

The article offers information on how could maternal allergies affect preterm outcomes in infancy. Topics include the prevalence of allergic diseases has been increasing, the large-scale epidemiological study has showed that one third of school-age children suffer from allergic diseases, and the children have multiple allergic diseases is suggesting that allergic diseases have become a significant health concern (Japan).

We present the case of a 6-year-old girl with cat-scratch disease (CSD), who developed severe pleuritis without lymphadenitis. Bartonella henselae DNA was detected on real-time polymerase chain reaction (PCR) analysis of whole blood. This is the first report of CSD diagnosed on real-time PCR using whole blood.
