| In the article entitled, "Long-term air-exposed functioning hydrocephalus valve with no infection," the authors describe an interesting case of an elderly patient whose ventriculoperitoneal shunt valve has eroded through the skin without a resulting shunt infection or malfunction. Clinical manifestations of infections with these organisms include abscesses (3), meningitis (4), ventriculoperitoneal shunt infection (5), spondylodiscitis (6), prosthetic joint infection (7), catheter-related bacteremia (2), and endocarditis (1).
