흡연은 전신뿐 아니라 구강에서 발생하는 다양한 질병의 중요한 위험 인자이며, 치과의사가 금연 치료에 참여하는 것은 개인의 전신 건강과 치주치료와 임플란트 치료 같은 치과 치료의 예후에도 큰 차이를 보여주는 것으로 알려져 있다. 흡연이 구강암과 같은 생명을 위협하는 비교적 흔치 않은 질병으로부터 경미한 구강 내 증상에 이르기까지 구강 환경에 다양한 영향성과 관련한 많은 근거가 있음에도 불구하고, 흡연과 구강건강의 관련성에 대한 환자들의 인식 수준을 조사한 연구는 적고, 금연진료에 대한 국내 치의학계의 관심과 참여는 더욱 부족하다. 그러므로 본 연구는 국내 치과 외래 환자의 흡연 양상과 치과계의 금연 진료 현황을 파악하여 금연 진료 방향을 모색해 보고자 하였다. 대한치과의사협회 문화복지부의 후원으로 전국 11개 치과대학병원의 구강내과, 구강외과 및 치주과 환자 중 825명이 니코틴 패치를 이용한 4주 금연 프로그램 및 설문에 참여하였고, 297명이 금연 설문에 참여하였다. 각 설문지 분석을 통해 각 치과대학병원의 조사 현황, 치과 외래 환자의 흡연 양상을 분석하였고, 치과에서 시행된 4주간의 금연 치료의 참여목적과 성공률을 조사하였다. 본 연구의 결과에 따르면, 흡연자는 주로 30-50대 중 장년층이 많았고, 흡연기간은 연령 증가에 비례하며, 하루 흡연량은 30대에서 가장 많았다. 금연시도는 30,40대에서 금연시도 비율이 높았고 그 기간은 대부분 1-3개월이었다. 흡연의 이유로는 스트레스 해소와 습관이 가장 높은 빈도를 보였으며 Heavy Smoking Index (HSI)는 20대가 가장 낮고 (71.4%) 60대가 가장 높았다(93.7%). 흡연 경고 문구에 대해 참가자의 68%는 금연을 떠올렸다. 구강질환(구강점막질환, 치주질환, 치아우식증)과 흡연의 관련성에 대한 실험참가자들의 인식도는 비교적 높았지만(50~68%) 금연 성공률은 일반 의과진료실에 비해 아주 낮은 결과를 보였다(22.7%). 흡연관련 질환 예방 업무에서의 치과의사의 중요성을 고려할 때, 금연치료에 치과의사들이 보다 적극적으로 참여할 수 있는 인식의 변화가 필요하다. 낮은 치료 성공율이 체계화되지 못한 진료내용 때문임을 고려할 때, 5As' 방법 등과 같은 금연관련 상담에 대한 지속적인 치과의사 교육과 환자 교육을 위한 다양한 자료의 개발을 통해 금연 성공률을 높일 수 있도록 해야 한다.

A total of 178 patients with primary lung cancer who had undergone complete resection of the tumor in combination with complete mediastinal lymphadenectomy were reviewed at the Department of Thoracic and Cardiovascular Surgery of Yonsei Medical Center from January 1980 through July 1989. Materials; 1. There were 45 men and 33 women ranging of age from 25 to 78 years with a mean age of 55.4 years. 2. Histological types were squamous carcinoma in 115 cases [64.6%] adenocarcinoma in 42 cases [23.6 %], bronchioloalveolar carcinoma in 9 cases [5.1%], large cell carcinoma in 8 cases [4.5 %] and small cell carcinoma in 4 cases [2.2%] Results were summarized as follows: 1. The size of primary tumor was not directly proportional to the frequency of mediastinal lymph node metastasis. [P =0.0567] 2. The histologic types of the primary tumor did not related to the incidence of mediastinal lymph node metastasis. [P >0.19] 3. The chance of mediastinal lymph node metastasis in the case with lung cancer located in right middle lobe[31.8%, N=22] and left lower lobe [31.4%, N=32] were the highest and the lowest was the one located in right lower lobe, while over all incidence of mediastinal lymph node metastasis in this series was 25.4 % [N=55]. 4. The rate of mediastinal lymph node metastasis without evidence of regional and hilar lymph node metastasis was 13%. [N=23] The chance of mediastinal lymph node involvement without N1 lymph node metastasis was 16.3 % [N=17] in both upper lobes and 8.2 % [N=6] in both lower lobes. It was statistically significant that the tumors in the upper lobes had greater chance of the mediastinal lymph node metastasis without N1 than the tumors in the lower lobes. 5. In this series majority of the patients with lung cancer the mediastinal lymph node metastasis from the tumor in each pulmonary lobes usually occurs via ipsilateral tracheobronchial and paratracheal lymphatic pathway. Especially the lung cancer located in lower lobes can metastasize to subcarinal, paraesophageal and inferior pulmonary ligamental lymph node through the lymphatic pathway of inferior pulmonary ligament. It can be speculated that in some cases of this series otherwise mediastinal lymph node metastasis can also occur with direct invasion to the parietal pleura and to the mediastinal lymph node via direct subpleural lymphatic pathway .

Purpose: Recently, The new Injury Severity Score (NISS) has become a more accurate predictor of mortality than the traditional Injury Severity Score (ISS) in the trauma population. Trauma Score Injury Severity Score (TRISS) method, regarded as the gold standard for mortality prediction in trauma patients, still contains the ISS as an essential factor within its formula. The purpose of this study was to determine whether a simple modification of the TRISS by replacing the ISS with the NISS would improve the prediction of in-hospital mortality in a trauma population with blunt head and neck trauma. Objects and Methods: The study population consisted of 641 patients from a regional emergency medical center in Kyoungsangnam-do. Demographic data, clinical information, the final diagnosis, and the outcome for each patient were collected in a retrospective manner. the ISS, NISS, TRISS, and modified TRISS were calculated for each patients. The discrimination and the calibration of the ISS, NISS, modified TRISS and conventional TRISS models were compared using receiver operator characteristic (ROC) curves, areas under the ROC curve (AUC) and Hosmer-Lemeshow statistics. Results: The AUC of the ISS, NISS, modified TRISS, and conventional TRISS were 0.885, 0.941, 0.971, and 0.918 respectively. Statistical differences were found between the ISS and the NISS (p=0.008) and between the modified TRISS and the conventional TRISS (p=0.009). Hosmer-Lemeshow chi square values were 13.2, 2.3, 50.1, and 13.8, respectively; only the conventional TRISS failed to achieve the level of and an excellent calibration model (p<0.001). Conclusion: The modified TRISS is a more accurate predictor of in-hospital mortality than the conventional TRISS in a trauma population of blunt head and neck trauma.

This study was conducted to provide a vitamin $B_{12}$ database for the representative Korean food items and to assess the dietary intake assessment of vitamin $B_{12}$ for Koreans. The vitamin $B_{12}$ content of 106 foods had been determined by high performance liquid chromatography (HPLC) using column switching method. Rich sources of vitamin $B_{12}$ were meats, milk, and egg ($0.3-3.4\;{\mu}g/100g$). Vegetables and fruits contained vitamin $B_{12}$ below limit of detection (LOD). The major food sources for vitamin $B_{12}$ intake were milk (72.0%), meats (22.3%), egg (3.6%), and fishes & shellfishes (2.1%). Mean vitamin $B_{12}$ intake of Koreans was $3.16\;{\mu}g$/person/day. The proportion of population with intake below estimate average requirement (EAR) and above recommended intake (RI) of vitamin $B_{12}$ was 60.7 and 36.5%, respectively. The vitamin $B_{12}$ intake level of young children with 1-2 years which was 834.6% of RI while the intake level of the older adults 50 years and older was only 70.0% of RI. Also, there were regional differences between urban and rural area. The population with intake below RI was larger than that with intake above RI in Korea.

We performed a molecular genetic study on the sequences of 18S ribosomal RNA (ITS1 region) gene in 4-day-old adult worms of Macroorchis spinulosus recovered in mice experimentally infected with metacercariae from crayfish in Jeollanam-do Province, Korea. The metacercariae were round, $180{\mu}m$ in average diameter, encysted with 2 layers of thick walls, but the stylet on the oral sucker was not clearly seen. The adult flukes were oval shape, and $760-820{\mu}m$ long and $320-450{\mu}m$ wide, with anterolateral location of 2 large testes. The phylogenetic tree based on ITS1 sequences of 6 M. spinulosus samples showed their distinguished position from other trematode species in GenBank. The most closely resembled group was Paragonimus spp. which also take crayfish or crabs as the second intermediate host. The present study is the first molecular characterization of M. spinulosus and provided a basis for further phylogenetic studies to compare with other trematode fauna in Korea.

Purpose: The purpose of this study was to evaluate the prognostic value of the lymph node ratio (LNR), which was defined as the proportion of involved nodes of all dissected nodes, in pN1 breast cancer. Materials and Methods: We retrospectively analyzed the clinical data of patients with pN1 breast cancer (n = 144) treated at Keimyung University Dongsan Medical Center, Daegu, Korea between 2001 and 2010. The median age was 46 years (range, 27 to 66 years). The LNR was 0.01-0.15 (low LNR) in 130 patients and >0.15 (high LNR) in 14 patients. Sixty-five patients (45.1%) had T1 tumors, 74 (51.4%) had T2 tumors, and 5 (3.5%) had T3 tumors. Eighty-eight patients (61.1%) underwent total mastectomy and 56 (38.9%) underwent partial mastectomy. Fifty-nine patients (41.0%) underwent radiotherapy and 12 (8.3%) underwent regional radiotherapy. The median follow-up period was 65 months. Results: The 5- and 10-year disease-free survival (DFS) rates were 92.7% and 82.4%, respectively. Univariate analyses revealed that high LNR (p = 0.004), total mastectomy (p = 0.006), no local radiotherapy (p = 0.036), and stage T2 or T3 (p = 0.010) were associated with worse DFS. In multivariable analysis, only high LNR (p = 0.015) was associated with worse DFS. Conclusion: High LNR is an independent prognostic factor in pN1 breast cancer and could be an indication for adjuvant radiotherapy in these patients.

The aim of this study is to find the relationship between interictal psychiatric symptoms and seizure-related variables such as structural changes, regional interictal perfusion changes, the number of interictal epileptic discharges and the presence of accompanying generalized tonic clonic seizure(GTC). The subjects were 75 patients (47 males : mean age $28.3{\pm}7.7$) with intractable epilepsy, Interictal psychiatric symptoms were rated by Symptom Checklist-90-R(SCL-90-R). Each of 4 seizure variables was measured by MRI, $^{99m}TC-HMPAO$ SPECT and the prolonged EEG monitoring. The mean SCL-90-R subscale T-scores and the ratio of the patients with definite psychiatric symptoms(T-score > 65 at any one subscale of SCL-90-R) were compared among the groups with different seizure variables. Demographic variables and clinical variables were not statistically different among the groups with different seizure variables. The patients with right mesial temporal sclerosis had higher mean SCL-90-R scores for obsessive compulsive symptom, interpersonal sensitivity, depression, hostility and psychotic symptoms than the patients with left mesial temporal sclerosis, and they also showed higher ratio of definite psychiatric symptoms. The presence of interictal epileptic discharges was related with higher T-scores of paranoid subscale. The areas of hypoperfusion, the presence of the GTC, and other clinical seizure variables showed no significant influences on the mean SCL-90-R subscale T-scores. from these results, the authors speculated that interictal subictal epileptic dischrages may be related with psychiatric symptoms of the intractable epileptic patients, especially with right mesial temporal sclerosis.

Objective : Paraclinoid segment internal carotid artery (ICA) aneurysms have historically been a technical challenge for neurovascular surgeons. The development of microsurgical approach, advances in surgical techniques, and endovascular procedures have improved the outcome for paraclinoid aneurysms. However, many authors have reported high complication rates from microsurgical treatments. Therefore, the present study reviews the microsurgical complications of the extradural anterior clinoidectomy for treating paraclinoid aneurysms and investigates the prevention and management of observed complications. Methods : Between January 2004 and April 2008, 22 patients with 24 paraclinoid aneurysms underwent microsurgical direct clipping by a cerebrovascular team at a regional neurosurgical center. Microsurgery was performed via an ipsilateral pterional approach with extradural anterior clinoidectomy. We retrospectively reviewed patients' medical charts, office records, radiographic studies, and operative records. Results : In our series, the clinical outcomes after an ipsilateral pterional approach with extradural anterior clinoidectomy for paraclinoid aneurysms were excellent or good (Glasgows Outcome Scale : GOS 5 or 4) in 87.5% of cases. The microsurgical complications related directly to the extradural anterior clinoidectomy included transient cranial nerve palsy (6), cerebrospinal fluid leak (1), worsened change in vision (1), unplanned ICA occlusion (1), and epidural hematoma (1). Only one of the complications resulted in permanent morbidity (4.2%), and none resulted in death. Conclusion : Although surgical complications are still reported to occur more frequently for the treatment of paraclinoid aneurysms, the permanent morbidity and mortality resulting from a extradural anterior clinoidectomy in our series were lower than previously reported. Precise anatomical knowledge combined with several microsurgical tactics can help to achieve good outcomes with minimal complications.
