We report a rare case of brain abscess secondary to mandibular odontogenic infection. A 50-year-oldman developed an abscess of the infratemporal fossa, masticatory myositis, and temporal myositis caused bylower first molar marginal periodontitis. Incision and drainage were performed by an intraoral approach, andantibiotics were administered intravenously. On the 8th disease day, vomiting occurred, but responded to anantiemetic drug. On the 9th disease day, extraction of lower first molar and adrasion was performed, resulting inthe alleviation of local symptoms. However, a persistent headache occurred, CT and MRI scans revealed a brainabscess and subdural abscess in the temporal lobe, immediately above the skull internal base. The patient wasgiven a diagnosis of brain abscess caused by odontogenic infection. The abscess almost disappeared after conservativetherapy administered at the department of brain surgery, and no sequelae were noted. The abscess apparentlyexpanded directly and continuously from the skull base through the foramen ovale and foramen spinosum.This case emphasizes the need to diagnose brain abscess and subdural abscess as complications of odontogenicinfection.

It is very important to provide safety information of new drugs to physicians and patients as soon as possible after the early postmarketing period. For that purpose, it is important to appropriately collect and analyze the spontaneous reports accumulated in databases of companies and regulatory agencies. This paper reviews the analytical methods to assess spontaneous reports. Bate et al. (1998) presented Bayesian Confidence Propagation Neural Network (BCPNN) Method used by Uppsala Monitoring Centre (UMC) of the World Health Organization (WHO). DuMouchel (1999) presented Gamma-Poisson Shrinker (GPS) Program of U. S. Food and Drug Administration (FDA), and Evans et al. (2001) presented Proportional Reporting Ratios (PRR) of the Medicines Control Agency (MCA). Furthermore, DuMouchel and Pregibon (2001) extended the GPS Program, proposing the Multi-Item Gamma Poisson Shrinker (MGPS) Program, which then became the standard method for the FDA. This report also reviews the practical problems (e.g. database, duplication cases, code of Medical Dictionary for Regulatory Activities (MedDRA)) encountered in Japan.
