52세 여자 환자는 약 6개월 전 발생한 우측 비폐색을 주소로 내원하였다. 신체 검사에서 우측 하부 내안각 부위에 무통성 종창이 관찰되었고, 압박 시 우측 눈물점에서 화농성 분비물이 있었다. 안와 전산화단층촬영(CT)과 안와 자기공 명영상(MRI)에서 우측 비누관에서 기인하며 안와와 비강까지 확장되어 있는 연부조직종괴가 관찰되었다. 우내측 상악절제술, 부분 전방 사골절세술, 부분 비골절 제술을 포함한 근치적 수술이 시행되었다. 수술 후 병리 소견상 누낭의 원발성 선양낭성암종으로 진단되었다. 환자는 수술 1달 후 보조 동시항암화학방사선요법을 시행받았다. 세 달 후 추적검사에서 임상적 및 방사선학적으로 재발 소견은 없었다. 국내에서 최초로 누낭의 원발성 선양낭성암종을 보고하는 바이다. A 52-year-old woman presented with a right nasal obstruction that was first noticed about 6 months earlier. Physical examination revealed a painless mass in the right inferior epicanthal fold area with a purulent discharge on the punctum on compressing the right inferior epicanthal fold area. Computed tomography (CT) and magnetic resonance imaging (MRI) delineated a soft tissue mass originating in the area of the right nasolacrimal duct, extending into the orbit and nasal fossa. Radical surgery, consisting of a right medial maxillectomy, partial anterior ethmoidectomy, and partial removal of the nasal bone was performed. The postoperative pathological diagnosis was primary adenoid cystic carcinoma of the lacrimal sac. One month postoperatively, adjuvant concurrent chemoradiotherapy was begun. The patient was clinically and radiologically free of the tumor at the 3-month follow-up. This case is the first report of primary adenoid cystic carcinoma arising from the lacrimal sac in Korea.

Objectives; The purpose of this study was to evaluate oral health status such as dental caries, periodontal disease, and TMJ related disease, dental treatment need, percentage of smoker, and oral health awareness of army corporals who came to Armed Forces Capital Hospital for regular medical check-up. Methods; Closed oral examination was conducted to 308 army corporals based on the Korea National Oral Survey criteria. The questionnaires related to awareness and attitude on oral health were received from the subjects. DMFT rate, DMFT, DT, MT, FT index, CPI index, percevied oral health status, percentage of smoker, tooth pain, periodontal bleeding, TMJ-related factor, and experience of oral education were evaluated. Results; DMFT rate was 68.2%, DMFT, DT, MT, FT index was 3.14, 0.7, 0.02, 2.42 respectively. 6.5% of subjects were needed periodontal treatment including scaling. 42.2% of subjects were smoker. Percentage of subjects who experienced tooth pain, periodontal bleeding, TMJ pain was 51.6%, 38.0%, 35.7% respectively. More than half of subjects eat or drink caries-induced food or drink more than once a day. Percentage of scaling experience within one year was 19.5%, 45.0% of subjects had no scaling experience. Only 17.9% of subjects had experience of oral health education. Conclusions; Oral health status of army corporals affects the Army dental health care system. Closed periodic oral examination and re-evaluation of oral health status on army corporals and should be performed regularly.

Objectives; The purpose of this retrospective study was to investigate the incidence and the factors of tooth loss in the patients with dental implant treatment in Armed Forces Capital Dental Hospital. Methods; 62 teeth which were lost during the duty, 278 teeth which were lost in the patients who serve over 20 years were included. Number of tooth loss by rank, location of tooth loss, reason for tooth loss, and percentage of fracture of oral and maxillofacial area was evaluated in the teeth lost during the duty. Location, period, reason of tooth loss, medical history, smoking, and additional treatment such as bone graft and sinus lift was evaluated in the teeth of the patients who serve over 20 years. Results; Most of tooth loss during the duty occurred in the soldier class, and maxillary central incisors. The reason for tooth loss was crown-root fracture(38.7%), root fracture(24.2%), crown fracture(17.7%), tooth avulsion(16.1%), and alveolar bone fracture(3.3%). Most of the tooth loss was located in the maxillary and mandibular molars in the patients who serve over 20 years. The reason for tooth loss in the patients was already lost(unknown cause, 48.4%), periodontal disease(39.4%), dental caries(7.7%), root fracture(2.8%), crown fracture(1.0%). More than half of the patients who serve over 20 years were smoker. Conclusions; Many soldiers are experiencing tooth loss, and dental implant could be a good treatment for functional aesthetic restoration. However, more efforts should be made to prevent tooth loss in the Army.

Background: Air pollution is an important risk factor for asthma, chronic obstructive pulmonary disease (COPD), and cardiovascular diseases. Air pollution can aggravate the symptoms of asthma, COPD, and cardiovascular diseases. Objective: A retrospective study was undertaken to investigate the relationship between monthly air pollutant concentrations and monthly hospitalizations for selected disease categories in Bucheon, Gyenggi-do. Method: Monthly measurements of particles (PM10), sulfur dioxide, ozone, and nitrogen dioxide (NO2) concentrations were obtained between Jan. 2003 and Aug. 2003 via the metropolitan network of monitoring stations. Hospital morbidity data for asthma, cardiovascular, COPD were obtained and categorized into all ages greater than 10 years. Result: There were significant associations for monthly changes in PM10 concentrations of emergency visits of female asthmatic patients (r=0.715, P=0.046) and outpatients visits of male asthmatic patients (r=0.714, P=0.047). There were significant associations for monthly changes in ozone concentrations and outpatient visits of COPD (r=0.723, P=0.043) and angina pectoris (r=0.802, P=0.017). Changes in NO2, sulfur dioxide concentrations were not significantly associated with any disease outcomes. Conclusion: These data provide useful information on the potential health impact of air pollution on asthma, COPD, cardiovascular diseases, and the control of air pollution is an important issue for prevention of respiratory and cardiovascular diseases.

Objective; Host, pathogens and environments are factors of creating dental caries. Dietary factor among environmental factors is affected by sugar contents and viscosity of food. The purpose of this study was to evaluate the viscosity and sugar contents of the Army Meal-Ready-to-Eat(MRE) and calculate the cariogenic potentiality index(CPI). Method; 7 types of MRE including hardtack were studied in the present study. Viscosity and sugar contents of each MRE were measured for 3 times by viscometer and glucose measuring machine. Cariogenic potentiality index was calculated by the formula[Cariogenic potentiality index(CPI) = 2.581343×sugar contents + 0.598324×viscosity]. Results; Army MREs had the high cariogenic potentiality index were special 1, special 3, special 2, type I 3, hardtack, FRH(Flameless Ration Heater), type S in order. Conclusion; Some of Army MREs have the high cariogenic potentiality index and may deteriorate the oral health condition of military personnel. It is recommended that broader and clinical studies are necessary to evaluate the effect of Army MRE on the oral health condition.

Objective; The objective of this study was to observe and evaluate the marginal bone loss around implant fixtures after dental implant prosthetic treatment in the military hospital. Method; The total 100 patients with 224 dental implants were studied in the present study. Intra-oral periapical radiograph and panorama radiograph were performed 6 month, 1 year, 2 year, 5 year, 10 year follow-ups after implant prosthetic treatments to observe the marginal bone loss around implant fixtures. The marginal bone loss level between area of implant fixtures was evaluated with Mann-Whitney U test. Results; The mean marginal bone loss of the dental implants was 1.41 ± 0.93mm at 6 months, 0.98 ± 0.27mm at 1 year, 1.05 ± 0.26mm at 2 years, 1.61 ± 0.72mm at 5 years, 2.19 ± 1.44mm at 10 years after dental implant prosthetic treatments. There were statistically no significant differences between areas of placement(anteriors vs posteriors) of dental implants after 6 month, 1 year, 2 year, 5 year, 10 year follow-ups. Conclusion; Military hospital provided the good and stable dental implant treatments for military patients. It is recommended that broader and long-term studies are necessary to evaluate the marginal bone loss after dental implant treatments. Novel oral health care program for patients with dental implant is necessary.
