Extracranial carotid artery aneurysm is a rare disease. A 72-year-old man was admitted with a painful neck mass for 5 days. Neck CT angiography and carotid duplex ultrasonography revealed a fusiform aneurysm of the left carotid bifurcation with a thrombus. His symptoms improved after anticoagulation therapy. The thrombus decreased in size and ultimately disappeared, as evidenced by serial duplex examinations. Carotid duplex ultrasonography is a simple and useful tool for diagnosis and follow-up.

We developed the system that enables patients to be treated at home during their daily life through digital telemetry and public communication line. In this study, video conference based remote examination and wireless telemetry were integrated together to form a remote monitoring homecare system, and underwent the validation. Test ECG signals were transmitted wirelessly unhindering the person's movement in one floor of our building, and the stability was assessed. The signal were transmitted to remote host via ISDN, with the patient's voice and moving image. To control the system and manage files remotely, the interactive model was devised for this study.

BACKGROUND: Serotonin transporter gene-linked polymorphism region(5-HTTLPR) and catechol-O-methyltransferase(COMT) genes are thought to be important factors in some personality traits and the etiology of anxiety disorder. The goal of this study was to determine the role of these genes in personality traits. METHOD: The participants included 116 healthy adults with no history of psychiatric disorders and other physical illness for the last 6 months. All participants were tested by Temperament and Character Inventory(TCI). The 5-HTTLPR, COMT val158met gene polymorphisms were analyzed with PCR(Polymerase Chain Reaction). Differences on TCI dimensions and sub-scales among groups were examined with t-test and ANOVA. RESULT: There were possible relationships of the 5-HTTLPR with self-transcendence(P=0.050) and COMT val158met polymorphism with cooperativeness(P=0.053). CONCLUSION: We found associations between 5-HTTLPR, COMT polymorphisms and the some TCI character dimensions. Further studies of polymorphisms of other genes and their interactions may clarify the complex relationship between personality and genes.

An acinar cell carcinoma of the exocrine pancreas is a rare tumor with reported a incidence of 1% to 2% of pancreatic carcinomas. Cases of acinar cell carcinomas with amphicrine features have been reported in recent decades. However, there are no reports of two simultaneous pancreatic masses: an endocrine tumor and, an exocrine tumor. We encountered a 59-year-old female patient presenting with abdominal pain and melena. The acinar cell carcinoma was a 1x1 cm-sized round solid mass in the head of the pancreas. The islet tumor was a 2.5x1.5 cm-sized round mass in the body of the pancreas. The endocrine tumor was nonfunctioning. Melena resulted from the hemosuccus pancreaticus due to a ductal invasion of the acinar cell carcinoma. The patient had a parathyroid adenoma with hyperparathyroidism. Therefore, both the islet tumor and parathyroid adenoma with hyperparathyroidism were strongly suggestive of a MEN I.

In order to discover lifespan-extending compounds made from natural resources, activity-guided fractionation of Zingiber officinale Roscoe (Zingiberaceae) ethanol extract was performed using the Caenorhabditis elegans (C. elegans) model system. The compound 6-gingerol was isolated from the most active ethyl acetate soluble fraction, and showed potent longevity-promoting activity. It also elevated the survival rate of worms against stressful environment including thermal, osmotic, and oxidative conditions. Additionally, 6-gingerol elevated the antioxidant enzyme activities of C. elegans, and showed a dose-depend reduction of intracellular reactive oxygen species (ROS) accumulation in worms. Further studies demonstrated that the increased stress tolerance of 6-gingerol-mediated worms could result from the promotion of stress resistance proteins such as heat shock protein (HSP-16.2) and superoxide dismutase (SOD-3). The lipofuscin levels in 6-gingerol treated intestinal worms were decreased in comparison to the control group. No significant 6-gingerol-related changes, including growth, food intake, reproduction, and movement were noted. These results suggest that 6-gingerol exerted longevity-promoting activities independently of these factors and could extend the human lifespan.

Objective: This study examined the characteristics of patients visiting the emergency department (ED) with fever after the chronification of the coronavirus disease 2019 (COVID-19) pandemic. Methods: This retrospective observational study analyzed the medical records of patients who visited the ED with fever from May 1 to October 31, 2021, and the corresponding period in 2019. This study was conducted at a single center in Seoul, Korea. Results: There was no statistical difference in the comorbidities of the patients of the two groups: the AC (after the COVID-19 pandemic) group and the BC (before the COVID-19 pandemic) group. As for the level of consciousness at the time of ED arrival, there was a significantly larger decrease in consciousness (verbal response or less) in the AC group than in the BC group (P=0.002). In the case of the National Early Warning Score (NEWS), the proportion was higher in the AC group in the moderate-risk and high-risk groups (P=0.003). The median time from symptom onset to ED arrival was 15.7 hours in the BC group and 13.8 hours in the AC group, and there was no significant difference (P=0.137). When leaving the ED, the AC group had a higher admission rate to the ward and intensive care unit than the BC group. There was no statistical difference in the in-hospital mortality between the two groups (2.9% and 2.4%, respectively; P=0.62). Conclusion Patients who visited the emergency room with fever after one year of the COVID-19 pandemic showed a similar time from symptom onset to ED arrival compared to patients who visited before the COVID-19 pandemic. In addition, there was no difference in in-hospital mortality among these patients compared to those with fever before the COVID-19 pandemic.

Objective: Early identification of COVID-19 in patients is important to prevent significant worsening of the disease. This study was undertaken to verify whether MEWS (Modified Early Warning Score), NEWS(National Early Warning Score), ROX index, and CURB-65, which are early diagnostic tools for severe respiratory diseases, could be applied to patients visiting the emergency room for COVID-19. Methods: This retrospective observational study included patients who visited an emergency medical center from September 1 to October 31, 2020, and from January 1 to February 28, 2021. Based on the vital signs and blood tests during the emergency room visit, severity evaluation tools and early diagnostic tools for severe cases were used and compared according to their area under the curve (AUC) values. The primary outcome was in-hospital mortality, while the secondary outcomes were intensive care unit admission rate and the need for mechanical ventilation based on these four tools (MEWS, NEWS, ROX index, and CURB-65). Results: A total of 667 patients were analyzed. No significant difference was determined between the non-survivor group and survivor group in the MEWS values (P=0.13), but statistically significant differences were observed for NEWS (5 vs. 1, P<0.05), CURB-65 (2 vs. 1, P<0.05), and ROX index (16.61 vs. 23.1, P<0.01). The AUC value of NEWS for death prediction indicated a good predictive power at 0.80, while that of MEWS showed a low predictive power at 0.57, which was statistically significant. Moreover, the AUC values of CURB-65 and ROX index did not differ significantly from values obtained for NEWS. Conclusion As early diagnostic tools for predicting death in COVID-19 patients, NEWS, ROX index, and CURB-65 showed excellent discrimination ability, whereas MEWS showed statistically and significantly lower discrimination ability.
