[Outcomes of surgical correction of congenital tibia pseudarthrosis depending on the activation of HHV-6/HHV-7 viral infection in a child with neurofibromatosis type-1].

Neurofibromatosis type-1 (NF-1)--is a common genetic disease effecting the skin, subcutaneous tissue peripheral nerves and bones (tibia pseudarthrosis). Immunomodulatory viruses HHV-6 and HHV-7 are classifying as a genus of roseoloviruses of subfamily beta-herpesviruses. Reactivation of HHV-6 and HHV-7 inhibits immune system and indirectly promote to other infectious agents. The article deals with a unique case repot of two repeated transplantations of fibula due to congenital tibia pseudarthrosis caused by NF-1. Results of the transplantations, related to active and latent HHV-6 and HHV-7 infection in a 6 years old child are discussed in the paper.
