We aimed to determine the effect of delivery mode on postnatal platelet count dynamics in neonates born to mothers with immune thrombocytopenia (ITP). This single-center, retrospective study included 41 mothers with ITP and their 65 infants born by vaginal delivery (VD, n = 30) and cesarean section (CS, n = 35) between January 1997 and March 2022. The median difference in platelet counts from day 0 to day 2 (ΔPlt [D 0-2]) was significantly lower in the VD group (- 39 × 10/L, interquartile range [IQR]: - 47 to - 24 × 10/L) than the CS group (15 × 10/L, IQR: - 6.

Small bowel obstruction (SBO) is a relatively uncommon urgent condition that may require surgical treatment. However, initial symptoms of patients who present with SBO are often nonspecific and may be confused with those of more common pediatric illnesses. Although the number of true SBO cases requiring emergency attention is few, distinguishing SBO from the more common less urgent pediatric abdominal conditions is vital for the most effective patient care.

Few patients with acute suppurative parotitis (ASP) due to group B streptococcus (GBS) have been documented. Limited data on clinical and microbiological features and infectious route are available. We present a 21-day-old boy with invasive GBS disease manifesting as ASP.

Unlabelled: Respiratory failure is one of the most common and critical problems in pediatric wards. Assessments by chest X-rays (CXRs) are common and prevalent for determining the cause of respiratory failure in children. However, CXRs can be misinterpretated.

Ultrasonography can be useful in the evaluation of children with abdominal complaints and may be the initial imaging modality in patients presenting with a newly recognized abdominal mass. Hepatoblastoma is an uncommon cause of acute abdominal pain in children and can rarely metastasize to the heart through vascular invasion. We report a case in which a 4-year-old girl who presented to the emergency department with abdominal pain promptly underwent point-of-care ultrasound and was subsequently diagnosed with intracardiac invasion of an abdominal tumor.

Background: The time-dependent changes that occur in children after acute encephalopathy are not clearly understood. Therefore, we assessed changes in brain function after suspected acute encephalopathy over time.

Methods: We created a database of children admitted to the pediatric intensive care unit at Kobe Children's Hospital because of convulsions or impaired consciousness with fever between 2002 and 2013.

The optimal timing of decompressive craniectomy in pediatric patients after presentation with malignant middle cerebral artery infarction is unknown. We report herein the case of a previously healthy 6-year-old Japanese girl who had good outcome after emergency decompressive craniectomy 116 h after malignant middle cerebral artery infarction. This case suggests that the timing of decompressive craniectomy can be delayed until deterioration of neurological findings and, compared with adults, a more prolonged time course for surgical intervention might be acceptable.
