Objectives: The objective of this study was to determine the effect of atrial fibrillation (AF) on the risk of dementia in the Korean elderly. Methods: A 10-year retrospective cohort study was conducted using the National Health Insurance Service-Senior Cohort database. We excluded those who were under 65 years of age as of January 2006 (n=46 113), those who were diagnosed with dementia between 2002 and 2005 (n=9086), and those with a history of stroke prior to AF diagnosis (n=8392). We used a Cox proportional hazards model with a time-varying covariate to determine whether AF is associated with the risk of dementia after adjusting for potential confounders. Results: In univariable Cox regression, the hazard ratio (HR) of dementia according to AF status was 1.28 (95% confidence interval [CI], 1.23 to 1.33). After adjusting for potential confounders, AF was found to increase the risk of dementia (HR, 1.12; 95% CI, 1.07 to 1.17), Alzheimer dementia (HR, 1.12; 95% CI, 1.07 to 1.17), and vascular dementia (HR, 1.10; 95% CI, 1.03 to 1.18). In patients diagnosed with AF, the incidence of dementia was lower (HR, 0.50; 95% CI, 0.47 to 0.52) in patients who were treated with oral anticoagulants. Conclusions: Investigating the potential risk factors of dementia in an aged society is important. We found a slightly higher risk of dementia in those with AF than in those without AF, and we therefore concluded that AF is a potential risk factor for dementia.

Objectives: This study was to compare the self-evaluated outcomes of communication competency in dental hygiene process of care in the students of a dental hygiene department with the teaching evaluation, and to confirm the difference of communication competency by the evaluator. Methods: This study attempted to confirm the value and usefulness of self-evaluation and teaching evaluation on the communication competency. The subjects of this study were 43 junior students who took a course of dental medical communication at the dental hygiene department of a university located in 'A' city, and the self-evaluation and teaching evaluation were conducted using the evaluation paper which was modified from the communication evaluation tool in the previous studies. The collected data were subjected to the correspondence sample t-test to compare the difference between the communication competency self-evaluation before and after the education, and after communication education, while an independent sample T-test was conducted to compare the differences between the evaluators. Results: The student's self-evaluations before and after the education showed the statistically significant difference, moreover, the post-education competency scores were improved mostly in all the items more than the pre-education competency scores. The score of self-evaluation was higher than that of the teaching evaluation in all items except one question in the case of history-information collection stage. Conclusions: It is confirmed that there is an effect to allow the students to improve their communication competency in the dental health communication education in the dental hygiene department. To evaluate the student's communication competency, the mutual complement of self-evaluation and teaching evaluation should be confirmed in parallel each other.

Purpose: To propose a standard value for the maxillary sinus volume of a normal Korean adult by measuring the width and height of the sinus and analyzing their correlation and the difference of the sinus size respectively between sexes, and on the right and left sides. Materials and Methods: Fifty-two (95 maxillary sinuses) out of 20 years or over aged patients who had taken CT in the Department of Dental Radiology, Yonsei University, Dental Hospital, between February 1997 and July 1999 who were no specific symptom, prominent bony septa, pathosis, clinical asymmetry and history of surgery in the maxillary sinus were retrospectively analyzed. Results: The mean transverse width, antero-posterior width, height and volume of the normal Korean adult's maxillary sinuses were 28.33 mm, 39.69 mm, 46.60 mm and 21.90 cm³, respectively. There was a significant sex difference in the sinus volume (p>0.05). In the mean antero-posterior width, height and volume of the sinus, no significant difference was observed between both sides. All four measurements showed a significant correlation between both sides (p>0.0001). The widths and height of the sinus all showed a significant correlation with the sinus volume (p>0.0001). Conclusion : In the Korean normal adult's maxillary sinus, males tended to be larger than females. Except for the transverse width, all of the measurements showed no significant difference between the right and left side, but significant correlations in the four measurements between both sides were observed. Thus, the overgrowth or undergrowth in the unilateral maxillary sinus may suggest a certain pathosis or developmental abnormalities in the maxillary sinus.

어린이 탈직장 11례 중 7례에서 5% 페놀을 포함한 글리세린액 직장점막하주사법을 이용한 경화요법을 시행하고 그 시술방법과 치료결과를 보고하였다. 이 방법은 간단하며, 단 1회 시술 후 6례에서 완치되어 치료율도 높았다. 시술 후 합병증이 없었다는 점과 실험적 조직소견으로 보아 본 치료법이 안전한 방법이며, 경화제에 의한 점막하층의 섬유화유발이 치료기전일 가능성의 증거도 제시되었다. 외래 혹은 입원상태에서의 국소요법 혹은 전신마취하 시술 등 상황에 따라 시술법도 자유롭게 선택할 수 있으나 시술 전 장청소과정과 시술 중 좌인지감각에 의한 주의깊은 점막하층 접근은 합병증을 피하기 위하여 반드시 지켜져야할 중요한 점으로 강조되어야 하겠다. 어린이의 탈직장에 대한 치료는 성인환자들과는 반드시 구분되어야 하며, 경화요법은 안전하고 편리하며 효과적인 우선적 치료법이라고 판단된다.

Purpose: Mycobacterium abscessus belongs to the group of rapid-growing atypical mycobacterium. The organism is ubiquitous and is found in soil, dust, and water. Although it rarely causes disease in humans, Mycobacterium abscessus has been associated with soft tissue infection. To the best of our knowledge, this is the first case report of facial soft tissue Mycobacterium abscessus infection in a healthy child in Korea. Methods: A 12-year-old girl presented with an erythematous skin lesion with serous discharge on her chin, which had been present for 3 weeks. On her history, she had a laceration wound on her chin at public bath and the lesion was repaired at emergency department immediately. Although conventional soft tissue infecton treatment, her lesion remains unhealed state and had serous discharge for 2 months. Moreover, we found a 1 cm sized nodular mass on her chin. Therefore we performed excision operation and referred the specimen to the laboratory for microbial and histopathologic study. Results: Pathology report confirmed the mass was enlarged lymph node with chronic necrotizing granulomatous inflammation with central microabscess. Non-Tuberculous mycobacterium identification test through tissue specimen resulted Mycobacterium abscessus. We prescribed clarithromycin for three weeks by oral administration as well as performed wound debridement and mass excision via previous wound. This way, her lesion appeared to be complete healing with minimal scarring. There were no evidence of inflammation sign or palpable mass. Conclusion: Although the prevalence is rare, Mycobacterium abscessus infections of soft tissue should be considered even in a healthy child with a lesion caused by trauma or which fails to respond to conventional treatment.

Nicotine poisoning arising from the use of nicotine patches is rare. However, because nicotine patches are classified as an OTC drug, the risk of misuse or abuse is increasing. Nicotine poisoning using nicotine patches shows an unusual clinical presentation compared to that from oral ingestion of multiple doses of nicotine. We present a case of misused nicotine patches that cause a nicotine poisoning. A thirty-nine year-old healthy man visited the ER with complaints of an intermittent cramping abdominal pain with nausea and vomiting. Upon physical examination, there were no specific findings except increased bowel sounds, and the patient's initial laboratory findings were also unremarkable except for an increased bilirubin level. CT revealed a mild degree of fatty liver. The patient's symptoms did not improve any further with conservative management. During his ED stay, we meticulously took his history again, and we discovered that he had used nicotine patches for three days, six days before admission, and had misused the nicotine patches as NSAID patches. The patient's diagnosis of nicotine poisoning was confirmed by a urine cotinine level ten times the normal value. After a 12-hour stay in the ED, his symptoms disappeared without any specific management.
