<P>To evaluate the clinical and imaging characteristics of patients with visually equivocal amyloid PET images, patients from the Alzheimer's Disease Neuroimaging Initiative cohort who had fluorine-18-florbetapir PET scans both at baseline and 24 months were selected. Five nuclear medicine physicians visually assessed the PET images and classified them as either positive or negative. Images not reaching a majority agreement were classified as equivocal. Among a total of 379 patients, the number of patients in each fluorine-18-florbetapir PET negative/equivocal/positive categories was 218 (57.5%), 32 (8.4%), and 129 (34.0%). Eight to 9% of patients with normal cognition (N=12/141), mild cognitive impairment (N=20/214), and no Alzheimer's disease (N=0/24) showed equivocal PET finding for each. In negative/equivocal/positive groups, positive cerebrospinal fluid A(1-42) was observed in 25.7, 81.5, and 98.3%, respectively. Baseline standardized uptake value ratios of fluorine-18-florbetapir PET were 0.75 +/- 0.05, 0.86 +/- 0.09, and 1.01 +/- 0.09, respectively [F(2,376)=603.547; P<0.001]. After 24 months of follow-up, the standardized uptake value ratios increased by 0.81 +/- 2.62, 2.81 +/- 2.90, and 2.17 +/- 3.66%, respectively [F(2,376)=7.905, P<0.05 vs. the negative group]. Among mild cognitive impairment patients, the equivocal group showed a more rapid decline in glucose metabolism than the negative group [5.52 +/- 5.36 vs. 0.67 +/- 4.45; F(2,122)=9.028, P<0.01]. 8.4% of the patients in this study showed a visually equivocal result of amyloid PET. These patients showed a moderate amount of amyloid accumulation and a rapid rate of accumulation.</P>
Possibility of subtropical moth influx by airflow in Jeju

Surveillance for introduction of subtropical moths through the inanimate pathway in the Korean Peninsula was carried from 2010 to the 2015 using the burket (light) trap in Jeju island and a nearby dependent islands. Each record typically includes the taxonomic identity, its country of origin, and relevant biological information. According to a study, Lampronia flavimitrella (Hübner) belonging to the family Prodoxidae, from the first reported in Korea. Interestingly, erebids moth, Asota ficus (Fabricius) was distributed in the subtropical area from the southern part of China to Sumatra. It has been also mentioned that the personal blog on the internet was colleted from Yeosu and Mt. Yudal-san (JN), respectively. Especially, there was a crambids moth, Bocchoris inspersalis Zeller, on the origin of subtropical Africa South of the Sahara, but we can't at this point give any evidence about the intercepted status of this species in Korea. We continuously investigated the moth fauna in Jeju. However, its possible of establishment and spread in the Korean fauna can't be ruled out. Thus, it is very important to our weather conditions and further study on the surveillance of these species are needed, considering its possible status as invasive alien species. To resolve this question, further researches should be done to determine the pathway by which these subtropical moths occurred in Korea.

<P>Conclusion: F-18-FP-CIT PETs with the first 10 minutes could be useful for the differential diagnosis of atypical Parkinson disorder by providing complementary FDG-like information to the dopamine transporter binding on late-phase FP-CIT images.</P>
