The purpose of this study is to determine how accuratively and reliably the Perdriollo s method can measure vertebral rotaton according to the level of vertebra and true axial rotation. Standard AP radiographs were taken using 10 dry human vertebra (two set of T3, T6, T9, T12, L3) with 5degrees increments in axial rotation, ranging from 0degrees to 50degrees. In order to evaluate the reliability of Perdriolle s method, three observers measured each radiograph twice, and intet-and intraobserver variance were estimated. The accuracy of Perdriolle's method was analyzed by total error analysis, root mean square error (RMSE) and Deviation of differences. 372 errors were made in the 660 measurement and 88.9% of all measurements were within +/- 5degrees of true rotation angle. There were no signigicant difference in the intraobserver measurement at each level whereas interobserver measurements were significantly different only at T3 level. The measurement was also the least accurate at T3 (RMSE=6.2292). We concluded that Perdriolle's method using torsion meter is an accurate and reliable one to measure the vertebral rotation with less accuracy and reliability in high thoracic level.

Listeria monocytogenes is the causative agent in a spectrum of human disease ranging from gastroenteritis to invasive infections such as meningitis, encephalitis, and septicemia. Elderly patients or persons who have lower cell-mediated immunity with predisposing conditions such as transplants, lymphomas, and AIDS, are especially susceptible. The tropism of L.monocytogenes for the central nervous system leads to severe disease, often with high mortality. We report a case of L. monocytogenes meningitis in a 58-year old woman with end stage renal disease. The patient was discharged without neurological sequelae after antibiotic treatment.

Parvimonas micra is a non-spore-forming anaerobic gram-positive coccus, widely distributed as normal flora in the skin, vagina and mucosa, and able to cause opportunistic infections, particularly endocarditis and brain abscess following dental manipulations. A 49-year-old woman was hospitalized due to fever and headache. She had been diagnosed with periodontitis at the beginning of fever. A brain abscess was noted in the right temporal lobe on the brain CT, and she was treated with ceftriaxone, isepamicin and metronidazole. In the next day, abscess was aspirated and drained by a surgical procedure. An organism was isolated from an anaerobic culture of the abscess aspirate, and was identified as P. micra by a commercial kit and 16S rRNA sequencing.
