To evaluate the principal features of focal cemento-osseous dysplasia (FocCOD) by systematic review (SR) and to compare their frequencies between four global groups.
Alternative names for FocCOD were used as search terms. The databases searched were the PubMed interface of Medline and LILACS (Literature Index for Latin-America and the Caribbean; Biblioteca Regional de Medicina (BIREME)). Only those reports of FocCODs which occurred in a series in the reporting authors' caseload were considered. All cases used radiographs and were confirmed fibro-osseous lesions histopathologically.
Of the 20 series considered, 10 were included in the SR. Five SR-included series were of East Asian communities. 64% of all SR-included cases were found incidentally. FocCOD predominantly affects females and the mandible. The three predominant radiological presentations varied significantly between reports.
The two at-risk global communities appear to be East Asians and those of black African origin. Although there appears to be little difference between East Asians and non-East Asians, the significant differences between them with regards to the predominant radiological presentation could suggest that either all communities vary in their presentation or that most, if not all, did not reflect the true frequency within their communities. Long-term follow-up of large series that would have revealed the long-term outcomes of FocCODs was lacking. This is necessary because of both FocCOD's predilection of edentulous areas, increasingly required for osseointegrated implants, and its wide differential diagnosis, which includes some lesions normally treated by surgery.

ABSTRACT: Describes a novel, computer-based approach to the objective
assessment of the symptoms of Parkinson's disease. The magnitude of
symptoms such as tremor, chorea and hesitation are particularly
important in the appropriate administration of drugs, such as L-Dopa,
used to improve patients' motor activities. The method adopted measures
the motor control of patients in real time using a commercially
available digitising tablet. Vector-based analysis of this data is then
performed to obtain an objective measurement of the symptoms under
investigation. Results are presented for a population of Parkinson's
patients and compared with results obtained from subjects without any
known neurological disorder. It is proposed that this technique is
sufficiently sensitive to aid precise administration of medication to
Parkinson's patients throughout the day, and thus to increase the
long-term benefits of such drug therapies

ABSTRACT: The paper describes a new integral equation method to solve 3D arbitrary discontinuity problems in a waveguide, where the potential type dyadic Green's function of the waveguide is used. Combining the network method and boundary element method, the generalized network parameters can be obtained directly. This method has a small memory size requirement and can achieve high accuracy
