Frontotemporal lobe dementia have been underevaluated because of various clinical features, changing diagnostic criteria, and indifference of clinicians. It is important that frontotemporal lobe dementia patient showing behavioral and lingual problems should be early diagnosed and treated. Because frontotemporal lobe dementia patients often confused with Alzheimer's disease, senile depression, schizophrenia, drug abuse. We have presented a case of frontotemporal lobe dementia. He had typical clinical history and symptoms which deserve to be considered frontotemporal lobe dementia. He showed appropriate findings of frontotemporal lobe dementia in the neuropsychological tests and brain magnetic resonance imaging and single photon emission computed tomography. This case is thought to be helpful for clinicians to give attention to early diagnosis and appropriate treatment of frontotemporal lobe dementia.

Angiodysplasia of small bowel is uncommon and frequently undiagnosed and presents a taxing surgical problem. It is usually diagnosed for unexplained gastrointestinal bleeding. For the surgeon, the main technical problem is that the lesion is impalpable, and invisible to the naked eye, so it usually cannot be identified unless bleeds actively at the time of surgery. Arteriography gives a little information about wax and wane pattern of bleeding in the lesion. Endoscopy is often unfruitful because the majority of lesions are submucosal and rarely exceed a few millimeters in diameter. Transillumination of the intestinal wall from inside of the lumen to the outside in a dark room can define the precise vascular anatomy of the wall. The delicate lesion of the angiodysplasia can be identified by this transillumination method. We described a simple intraoperstive endoscopic translllumination technique used successfully to identify an angiodysplasia in the small bovwel prior to the bowel resecion. This report summarized our experience and review of literature.

OBJECTIVES: This study aimed to compare the behavioral psychological symptoms of dementia by stages and to suggest the proper management treatment plan. METHODS: We examined behaviral psychological symptoms in 17 dementia patients with mild stage (CDR=0.5, 1), 18 dementia patients with moderate stage (CDR=2) and 24 dementia patients with severe stage (CDR=3, 4). We compared the prevalence and the composite scores (frequency X severity) of each behavioral domain in K-NPI among three groups. The MMSE-K, GDS, Barthel ADL were also administrated to evaluate the general cognitive function, severity of the patients and activity of daily living. RESULTS: The most common behavioral disturbances were apathy/indifference, depression/dysphoria, and aberrant motor behavior. The mean composite score of aberrant motor behavior increased by stages of dementia severity with statistical significance. The total score of the K-NPI increased with severer stages of dementia the result didn't show statistical significance. The K-NPI score showed the positive correlation with CDR, GDS and the negative correlation with MMSE-K, B-ADL. But, there was no statistically significant correlation. CONCLUSION: Behavioral and Psychological Symptoms of Dementia (BPSD) change by the stages of dementia. The practical guideline for BPSD management according to dementia stage is needed. Re-evaluation and new therapeutic inter-vention must be considered by the stages of dementia.

OBJECTIVE: The purpose of this study is to find out the effect of ApoE genotype in correlation between metabolic syndrome and cognition of the elderly in the community. METHODS: A total of 1,305 subjects (440 men and 865 women) aged 60-98 years were analyzed from preliminary data of Gwangju Dementia and MCI Study (GDEMCIS). The metabolic syndrome was assessed as defined by the modified National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III). The study questionnaire consisted of demographic characteristics, current and past illness history, drug history, family history of dementia and stroke, and Korean version-Mini Mental State Examination (K-MMSE). We also examined ApoE genotype and analyzed associated factors with metabolic syndrome. RESULTS: These Metabolic syndrome was present in 28.6% of the subjects (13.4% of men and 36.3% of women). On multiple logistic regression analysis, low serum HDL cholesterol was associated with an increased risk for cognitive impairment (K-MMSE score < or = 17) adjusted by age, sex, educational level, and smoking in the presence of ApoE epsilon4 allele (OR 0.95, 95% CI 0.92-0.99). CONCLUSION: These results suggest that serum HDL cholesterol may affect cognitive function in the elderly in the presence of ApoE epsilon4 allele.

BACKGROUND: The purpose of this study is to find out the effect of ApoE genotype on the relationship between nutritional risk and cognition of the elderly in a community. METHODS: A total of 996 subjects (343 men and 653 women) aged 60~91 years were analyzed from preliminary data of GDEMCIS (Gwangju Dementia and MCI Study). The study questionnaire consisted of demographic characteristics, current and past illness history, drug history, K-SGDS (Korean version of Short Form Geriatric Depression Scale), K-MMSE (Korean version-Mini Mental State Examina- tion), and NSI (Nutritional Screening Initiative) checklist. We also examined blood pressure, fasting serum glucose, lipid profile, body mass index, and ApoE genotyping. RESULTS: 649 subjects (65.2%) were on good nutritional state (NSI score < or = 2) and 347 subjects (34.8%) were on moderate or high nutritional risk (NSI score > or = 3). On multiple logistic regression analysis, moderate or high nutritional risk was associated with an increa- sed risk for cognitive impairment (K-MMSE score < or = 17) after adjustment with age, sex, K-GDS and educational level in the absence of ApoE epsilon4 allele (OR 1.78, 95% CI 1.15-2.77). CONCLUSION: These results suggest that nutritional risk may be associated with cognitive function in the elderly only in the absence of ApoE epsilon4 allele.

Humanity is in the midst of the coronavirus disease 2019 (COVID-19) pandemic, and vaccines—including mRNA vaccines—have been developed at an unprecedented speed. It is necessary to develop guidelines for vaccination for people undergoing treatment with assisted reproductive technology (ART) and for pregnancy-related situations based on the extant laboratory and clinical data. COVID-19 vaccines do not appear to adversely affect gametes, embryos, or implantation; therefore, active vaccination is recommended for women or men who are preparing for ART. The use of intravenous immunoglobulin G (IVIG) for the treatment of immune-related infertility is unlikely to impact the effectiveness of the vaccines, so COVID-19 vaccines can be administered around ART cycles in which IVIG is scheduled. Pregnant women have been proven to be at risk of severe maternal and neonatal complications from COVID-19. It does not appear that COVID-19 vaccines harm pregnant women or fetuses; instead, they have been observed to deliver antibodies against severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) to the fetus. Accordingly, it is recommended that pregnant women receive COVID-19 vaccination. There is no rationale for adverse effects, or clinical cases of adverse reactions, in mothers or neonates after COVID-19 vaccination in lactating women. Instead, antibodies to SARS-CoV-2 can be delivered through breast milk. Therefore, breastfeeding mothers should consider vaccination. In summary, active administration of COVID-19 vaccines will help ensure the safe implementation of ART, pregnancy, and breastfeeding.

Coxsackievirus B3 (CVB3) infection causes acute pancreatitis and myocarditis. However, its pathophysiological mechanism is unclear. Here, we investigated how lipid metabolism is associated with exacerbation of CVB3 pathology using high-fat diet (HFD)-induced obese mice. Mice were intraperitoneally inoculated with 1×10 6 pfu/mouse of CVB3 after being fed a control or HFD to induce obesity. Mice were treated with mitoquinone (MitoQ) to reduce the level of mitochondrial ROS (mtROS). In obese mice, lipotoxicity of white adipose tissue-induced inflammation caused increased replication of CVB3 and mortality.The coxsackievirus adenovirus receptor increased under obese conditions, facilitating CVB3 replication in vitro. However, lipid-treated cells with receptor-specific inhibitors did not reduce CVB3 replication. In addition, lipid treatment increased mitochondria-derived vesicle formation and the number of multivesicular bodies. Alternatively, we found that inhibition of lipid-induced mtROS decreased viral replication. Notably, HFD-fed mice were more susceptible to CVB3-induced mortality in association with increased levels of CVB3 replication in adipose tissue, which was ameliorated by administration of the mtROS inhibitor, MitoQ. These results suggest that mtROS inhibitors can be used as potential treatments for CVB3 infection.
