Background and Purpose Previous studies have assessed the relationship between cerebral vessel tortuosity and intracranial aneurysm (IA) based on two-dimensional brain image analysis. We evaluated the relationship between cerebral vessel tortuosity and IA according to the hemodynamic location using three-dimensional (3D) analysis and studied the effect of tortuosity on the recurrence of treated IA. Methods We collected clinical and imaging data from patients with IA and disease-free controls. IAs were categorized into outer curvature and bifurcation types. Computerized analysis of the images provided information on the length of the arterial segment and tortuosity of the cerebral arteries in 3D space. Results Data from 95 patients with IA and 95 controls were analyzed. Regarding parent vessel tortuosity index (TI; P<0.01), average TI (P<0.01), basilar artery (BA; P=0.02), left posterior cerebral artery (P=0.03), both vertebral arteries (VAs; P<0.01), and right internal carotid artery (P<0.01), there was a significant difference only in the outer curvature type compared with the control group. The outer curvature type was analyzed, and the occurrence of an IA was associated with increased TI of the parent vessel, average, BA, right middle cerebral artery, and both VAs in the logistic regression analysis. However, in all aneurysm cases, recanalization of the treated aneurysm was inversely associated with increased TI of the parent vessels. Conclusions TIs of intracranial arteries are associated with the occurrence of IA, especially in the outer curvature type. IAs with a high TI in the parent vessel showed good outcomes with endovascular treatment.

An infection is less likely to elicit chronic inflammatory demyelinating polyneuropathy (CIDP) than Guillain-$Barr{\acute{e}}$ syndrome. We here report a case of acute-onset CIDP following hepatitis A virus infection and briefly comment on the potential mechanisms regarding the induction and chronicity of autoimmunity after a viral infection.

Objectives: The purpose of the study is to investigate the participation motivation and satisfaction of continuing education in the dental hygienists. Methods: A self-reported questionnaire was completed by 900 dental hygienists in Seoul and Gyeonggido in continuing education 2015. The questionnaire consisted of general characteristics of the subjects (7 items), continuing education requirements (6 items), and continuing education evaluation (9 items). Cronbach’s alpha was 0.859 in participation motivation and 0.901 in satisfaction. Likert five point scale was used. Data were analyzed by SPSS 22.0 program. Results: The priorities of the contents were as follows; patient care and counseling(49.0%), the latest information and technology(43.9%), middle management roles(23.3%), health care management(17.6%), and lecture studies(4.4%) in order by multiple responses survey. The favorite instructors were specialized dental hygienist(52.3%). The ideal pay for education fee was 50 percent supported by the institution. The best official announcement of education was e-mail. The participation motivation of education was 4.45 points and was focused on the education completion issue. The lowest score was 2.77 of development of human relationships between participants. The choice for instructor was 3.43 and the lowest score was 2.49 of education fee. Overall satisfaction score was 3.04. Conclusions: Diversification of the continuing education is very important. It is necessary to develop and implement the education methods and to train the dental hygiene specialists for the education.
