A concept analysis of children with complex health conditions: implications for research and practice.

Background: This concept analysis aimed to clarify the meaning of "children with complex health conditions" and endorse a definition to inform future research, policy, and practice.

Methods: Using Walker and Avant's (2011)'s approach, we refined the search strategy with input from our team, including family representatives. We reviewed the published and grey literature.

Lymphocytic choriomeningitis virus: reemerging central nervous system pathogen.

Lymphocytic choriomeningitis virus (LCMV), a human zoonosis caused by a rodent-borne arenavirus, has been associated with both postnatal and intrauterine human disease. Infection in man is acquired after inhalation, ingestion, or direct contact with virus found in the urine, feces, and saliva of infected mice, hamsters, and guinea pigs. Congenital LCMV infection is a significant, often unrecognized cause of chorioretinitis, hydrocephalus, microcephaly or macrocephaly, and mental retardation.
