Abstract:
Objective To understand the epidemiological characteristics of central nervous system(CNS)infectious diseases in children hospitalized in capital institute of pediatrics.Methods All the 972 patients hospitalized in capital institute of pediatrics with the clinical diagnosis of CNS infectious diseases were analyzed from Jan.1997 to Dec.2006 retrospectively.The etiological detection of serum and/or cerebrospinal fluid(CSF)samples in acute stage collected from those patients included smear,cultivation and rapid etiological diagnosis of bacterium and fungus;determination of viral antibody,mycoplasma pneumonia antibody and tuberculous antibody.Results 1.A total of 972 patients were treated for CNS infectious diseases,accounting for 1.76% of inpatients of Internal Medicine at the same time.2.The main sources of CNS infectious diseases :747 cases of viral encephalitis,177 purulent meningitis,21 mycoplasmal encephalitis and 12 tuberculous meningitis.3.The ratio of male and female was 1.72:1.0 and the mean onset age was(4.75?4.03)years.4.Special infectious agents in serum and/or CSF samples were positive in 283(29.12%)cases.The total bacterial positive cases were 48/177 cases(27.12%).Streptococcus pneumonia(4.52%)was the most,followed by Escherichia coli(3.39%),Neisseria meningitides(3.39%)and Haemophilus influenzae B(Hib,3.39%).Viral antibodies were positive in 210/747 cases(28.11%).The major agents were herpes virus(HV)[128/747 cases(17.14%)]and enterovirus(EV)[91/747 cases(12.18%)].Conclusions CNS infectious diseases were important ones hospitalized in internal medicine of capital institute of pediatrics.Virus and bacterium were the main causes of CNS infectious diseases.Streptococcus pneumonia,Escherichia coli,Neisseria meningitides and Hib were the main agents of purulent meningitis.HV and EV were the main sources of viral encephalitis.
