Molecular Epidemiology of Colonization in Families With Infants.

Background: Community-associated infection is a major public health hazard to adults and older children. Infants frequently excrete toxigenic asymptomatically in their stool, but their importance as a community reservoir of is uncertain.

Methods: Families of healthy infants were recruited at the baby's 4-month well child visit and were followed longitudinally until the baby was approximately 9 months old.

Endovascular treatment of a ruptured pure arterial malformation and associated dysplastic middle cerebral artery dissecting aneurysm: illustrative case.

Background: Pure arterial malformations are characterized as unique cerebrovascular lesions with a dilated, coil-like appearance and tortuous arteries without early venous drainage. Historically, these lesions have been described as incidental findings with a benign natural history. However, pure arterial malformations can rarely demonstrate radiographic progression and develop associated focal aneurysms with an unclear risk of rupture.

Pediatric diffuse hemispheric glioma H3 G34-mutant with gains of the BRAF locus: An illustrative case.

Diffuse hemispheric glioma, H3 G34-mutant, is a recently recognized distinct high-grade glioma with a dismal prognosis. In addition to the H3 G34 missense mutation, numerous genetic events have been identified in these malignant tumors, including , , and, rarely, genes. There are only a few reports to date that have identified mutations in diffuse hemispheric glioma, H3 G34-mutant.
