Limits of early diagnosis of herpes simplex encephalitis in children: a retrospective study of 38 cases.

The prognosis of herpes simplex encephalitis (HSE) depends on the early and appropriate administration of specific antiviral therapy. We retrospectively reviewed 38 cases of children with proven HSE, to evaluate the reliability of polymerase chain reaction results, according to the time of cerebrospinal fluid (CSF) sampling. Initial negative results were observed in 8 of 33 CSF samples drawn before day 3 of the disease and were significantly associated with a low level of protein and <10 leukocytes/mm3 in the CSF.Journal Articleinfo:eu-repo/semantics/publishe

Repulsion exerted on a spherical particle by a polymer brush

The steric repulsion exerted on spherical particles by a semidilute polymer brush is evaluated using numerical self-consistent field theory (SCFT) in cylindrical coordinates. This accurate treatment provides the opportunity to test the conventional analytical approach, where the strong-stretching theory (SST) of Milner, Witten, and Cates for uniform compression can be adapted to particles of any shape using the Derjaguin approximation. While the Derjaguin approximation works well, at least, for the interaction energy, the SST proves to be seriously inaccurate for realistic grafting densities. Nevertheless, an efficient and accurate treatment for arbitrarily shaped particles remains possible if the uniform compression in the Derjaguin approximation is supplied by SCFT.close464
