    Author: Limeres-Posse J, Tomás-Carmona I, Fernández-Feijoo J, Martínez-Vázquez C, Castro-Iglesias A, Diz-Dios P.
    Journal: Rev Neurol; ; 37(3):201-6. PubMed ID: 12938049.
    Abstract:
    INTRODUCTION: It has been suggested that between 3% and 13% of the cerebral abscesses (CA) are presumably associated to oral infections or dental procedures. AIM: Determine the prevalence of CA of oral origin, discussing their clinical and microbiological characteristics. PATIENTS AND METHODS: Retrospectively, 54 cases of CA diagnosed in 3 hospitals of Galicia between 2001 and 2002 were reviewed. RESULTS: A presumed oral portal of entry was recorded in 6 patients (11.1%); 4 cases were associated to oral infections and the remaining 2 had received dental treatment in the months prior to the onset of symptoms. Half of the patients showed irrelevant medical record, 2 had had previous extracranial abscesses and 1 presented a type A immunoglobulin deficiency. In 4 cases, the microbiological analysis was positive and typical oral bacteria (Streptococcus viridans and Peptostreptococcus spp.) were identified. CONCLUSIONS: The results of this study suggest that a significant number of CA are probably of oral origin. In consequence, to maintain a good oral health status is important and specific prophylactic measures before any dental procedure should be applied, especially in patients with risk recognized factors.
