[Meningoencephalitis and generalized infections in children (clinico-morphological comparisons)].

The results of morphological investigation of 254 children who have died in Leningrad from the currently most topical viral, bacterial, and mycoplasmic neuroinfections are analyzed. The authors describe the changes related to the properties of the causative agent, the nature of infection (intrauterine or postnatal), and to the duration of the disease. Clinical findings are collated with the literature data. Different meningoencephalitides show considerable polymorphism of the clinical symptomatology and structural alterations. The principles of the reliable etiological diagnosis of neuroinfections are validated. The authors propose that the terms 'meningoencephalitis' and 'generalized infection with cerebral involvement' be used differentially.
