Objectives: The purpose of this study was to identify the effects of music intervention on the patient's fear and anxiety during scaling. Methods: 360 patients who had visited W University dental hygiene laboratory were selected as study subjects and divided into experiment group and control group. Results: Study results showed that the control group (71.9%) and the experimental group (75.1%) had experiences avoiding dental treatment due to fear. In the control group (37.6%) and experimental group (40.6%), the highest influencing factor was the sound of machine and followed by pain. The experimental group preferred classical music, followed by pop songs, trot music and instrumental music. In the experimental group (83.3%), fear and anxiety were alleviated by music, and 77.9% of the patients mentioned they would recommend music for scaling to other patients. There was an interaction effect (p=0.014) between the groups before and after the measurement of the lowest blood pressure. There was a significant difference in pulse before and after pulse measurement (p=0.000). There was a significant difference in respiration between groups (p=0.042) and before and after respiration (p=0.030). Conclusions: Study results showed that music intervention that utilizes music during scaling showed significant effects on the alleviation of fear and anxiety, affecting Pulse number among vital signs. Therefore, more systematic program is to be required to alleviate dental fear and anxiety with music therapy not only for scaling, but also for dental clinic in the future.

Background: Chronic nonspecific symptoms attributed to indoor nonindustrial work environments are common and may cause disability, but the medical nature of this disability is unclear. The aim was to medically characterize the disability manifested by chronic, recurrent symptoms and restrictions to work participation attributed to low-level indoor pollutants at workplace and whether the condition shares features with idiopathic environmental intolerance. Methods: We investigated 12 patients with indoor aire-related work disability. The examinations included somatic, psychological, and psychiatric evaluations as well as investigations of the autonomic nervous system, cortisol measurements, lung function, and allergy tests. We evaluated well-being, health, disability, insomnia, pain, anxiety, depression, and burnout via questionnaires. Results: The mean symptom history was 10.5 years; for disabling symptoms, 2.7 years. Eleven patients reported reactions triggered mainly by indoor molds, one by fragrances only. Ten reported sensitivity to odorous chemicals, and three, electric devices. Nearly all had co-occurrent somatic and psychiatric diagnoses and signs of pain, insomnia, burnout, and/or elevated sympathetic responses. Avoiding certain environments had led to restrictions in several life areas. On self-assessment scales, disability showed higher severity and anxiety showed lower severity than in physician assessments. Conclusion: No medical cause was found to explain the disability. Findings support that the condition is a form of idiopathic environmental intolerance and belongs to functional somatic syndromes. Instead of endless avoidance, rehabilitation approaches of functional somatic syndromes are applicable.

Purpose: This study aimed to evaluate the effects of sentinel lymph node biopsy (SLNB) on recurrence and survival after neoadjuvant chemotherapy (NAC) in breast cancer patients with cytology-proven axillary node metastasis. Methods: We selected patients who were diagnosed with invasive breast cancer and axillary lymph node metastasis and were treated with NAC followed by curative surgery between January 2007 and December 2014. We classified patients into three groups: group A, negative sentinel lymph node (SLN) status and no further dissection; group B, negative SLN status with backup axillary lymph node dissection (ALND); and group C, no residual axillary metastasis on pathology with standard ALND. Results: The median follow-up time was 51 months (range, 3-122 months) and the median number of retrieved SLNs was 5 (range, 2-9). The SLN identification rate was 98.3% (234/238 patients), and the false negative rate of SLNB after NAC was 7.5%. There was no significant difference in axillary recurrence-free survival (p=0.118), disease-free survival (DFS; p=0.578) or overall survival (OS; p=0.149) among groups A, B, and C. In the subgroup analysis of breast pathologic complete response (pCR) status, there was no significant difference in DFS (p=0.271, p=0.892) or OS (p=0.207, p=0.300) in the breast pCR and non-pCR patients. Conclusion: These results suggest that SLNB can be feasible and oncologically safe after NAC for cytology-determined axillary node metastasis patients and could help reduce arm morbidity and lymphedema by avoiding ALND in SLN-negative patients.

최근 활로 4징 교정술의 향상된 성적에도 불구하고, 수술 후 폐동맥 폐쇄부전과 우심실 유출로 확장으로 인한 좌폐동맥의 뒤틀림과 협착의 가능성이 보고되고 있다. 이에 좌폐동맥의 협착이 동반되었거나 협착이 없더라도 우심실 유출로 첩포 확장 시 좌폐동맥이 예각을 이루어 좌폐동맥 뒤틀림의 가능성이 있는 환자에서 첩포를 사용하지 않고 자가 주폐동맥 플랩만을 이용한 새로운 좌폐동맥 혈관성형술의 결과를 보고하고자 한다. 대상 및 방법： 1998년 10월부터 2001년 1월까지 24명의 활로4징 환자에서 완전교정술 시 좌폐동맥 입구를 자가 주폐동맥 플랩을 이용하여 선택적으로 혈관성형술을 시행하였다. 환자의 연령(중앙값)은 10개월(4∼145개월)이었다. 주폐동맥 플랩 좌폐동맥 성형술은 좌폐동맥 입구의 협착이 있었던 19예(79%)와 해부학적 협착은 없었으나 주폐동맥과 좌폐동맥이 예각을 이루어 좌폐동맥 뒤틀림의 위험이 예상되는 5예(21%)에서 시행되었다. 결과: 수술 사망예는 없었다. 24명 중 15명(62%)에서 경판막윤 우심실유출로 확장술을 시행하였으며, 나머지 9명에서 폐동맥 판막윤을 보존하면서 폐동맥 혹은 누두부 확장술을 시행하였다. 24명 중 5명(21%)에서는 어떤 첩포도 사용하지 않고 자가 주폐동맥 플랩만으로 좌폐동맥을 포함한 주폐동맥확장술을 시행하였다. 1 명을 제외한 23명의 추적관찰 기간(중앙값)은 20개월(6∼42개월)이었으며, 만기 사망 및 재수술의 예는 없었다. 2명에서 우폐동맥 근위부 협착으로, 1명에서 좌, 우폐동맥 입구의 협착으로 풍선 혈관성형술이 필요하였다. 결론: 주폐동맥 플랩을 이용한 좌폐동맥 성형술의 보다 장기적인 관찰이 필요하나, 첩포를 사용하지 않아 이와 관련된 문제점들을 피할 수 있고, 자가 주폐동맥플랩의 성장을 기대할 수 있을 것으로 생각된다. 또한 주폐동맥과 좌폐동맥 사이를 둔각으로 유지함으로써 향후 폐동맥 폐쇄부전과 관련된 우심실유출로 확장에 의한 좌폐동맥의 뒤틀림의 가능성을 줄일 수 있을 것으로 생각한다.

Purpose: Use of radiotherapy combined with chemotherapy is increasing in hypopharyngeal cancer. However, many show residual tumor after radiotherapy. Timing for treatment evaluation and salvage therapy is essential. However, optimal timing for salvage surgery has not been suggested. In this study, we tried to evaluate optimal timing for salvage surgery. Methods and Materials: Patients who were diagnosed with hypopharyngeal squamous cell carcinoma between 2006 and 2015 were retrospectively analyzed. All patients received definitive radiotherapy with or without chemotherapy. Response of all treated patients were analyzed at 1, 3, and 6 months after radiotherapy. Any patients with progression before 6 months were excluded. Results: A total of 54 patients were analyzed. Complete remission (CR) rates at 1 month (CR₁), 3 months (CR₃) and 6 months (CR₆) were 66.7%, 81.5%, and 90.7%, respectively. Non-CR at 1 month (NCR₁), 3 months (NCR₃), and 6 months (NCR₆) showed poor locoregional recurrence-free survival rates (1-year rates of 63.7%, 66.7%, and 0.0%, respectively) compared to CR₁, CR₃, and CR₆ (1-year rates 94.3%, 88.0%, and 91.5%, respectively). Particularly significant differences were seen between CR₆ and NCR₆ (p < 0.001). Of 10 patients with NCR₃, 5 showed CR at 6 months (NCR₃/CR₆). There was no statistical difference in locoregional recurrence-free survival between CR₃ and NCR₃/CR₆ group (p = 0.990). Conclusion: Our data suggest half of patients who did not show CR at 3 months eventually achieved CR at 6 months. Waiting until 6 months after radiotherapy may be appropriate for avoiding additional salvage therapy.

BACKGROUND/OBJECTIVES: Despite the importance of a low-iodine diet (LID) for thyroid cancer patients preparing for radioactive iodine (RAI) therapy, few studies have evaluated dietary intake during LID. This study evaluated the amount of dietary iodine intake and its major food sources during a typical diet and during LID periods for thyroid cancer patients preparing for RAI therapy, and examined how the type of nutrition education of LID affects iodine intake. SUBJECTS/METHODS: A total of 92 differentiated thyroid cancer patients with total thyroidectomy were enrolled from Seoul National University Hospital. All subjects completed three days of dietary records during usual and low-iodine diets before $^{131}I$ administration. RESULTS: The median iodine intake was $290{\mu}g/day$ on the usual diet and $63.2{\mu}g/day$ on the LID. The major food groups during the usual diet were seaweed, salted vegetables, fish, milk, and dairy products and the consumption of these foods decreased significantly during LID. The mean energy intake on the LID was 1,325 kcal, which was 446 kcal lower than on the usual diet (1,771 kcal). By avoiding iodine, the intake of most other nutrients, including sodium, was significantly reduced during LID (P < 0.005). Regarding nutritional education, intensive education was more effective than a simple education at reducing iodine intake. CONCLUSION: Iodine intake for thyroid cancer patients was significantly reduced during LID and was within the recommended amount. However, the intake of most other nutrients and calories was also reduced. Future studies are needed to develop a practical dietary protocol for a LID in Korean patients.

심장 박동상태에서 시행하는 관상동맥우회술(off-pump CABG)은 심폐체외순환하에서 시행하는 관상동맥우회술(on-pump CABG)에 비해 수술 후 유병률을 줄일 수 있는 방법으로 보고되고 있다. 저자들은 특히 수술 후 합병증의 발생 가능성이 높은 당뇨환자에 있어서 off-pump CABG와 on-pump CABG의 임상 결과를 비교하여 off-pump CABG가 당뇨환자의 유병률에 미치는 영향을 알아보고자 한다. 대상 및 방법: 2001년 1월부터 2003년 6월까지 연세대학교 심장혈관병원에서 관상동맥우회출만을 시행받은 682명(off-pump CABG군: 424명, on-pump CABG: 258명)의 환자들 중 당뇨가 있는 환자 244명을 대상으로 하였다. 이 중 off-pump CABG는 154명, on-pump CABG는 90명의 환자들에서 시행하였다. 이 환자들을 대상으로 수술 전 위험요소들과 수술 후 결과를 비교하였다. 결과: 연령, 남녀 비 및 수술 전 고혈압 등의 위험요소와, 수술 전 뇌경색이나 심근경색의 기왕력 등 수술위험 요소도 두 군간의 통계적인 차이를 보이지 않았다. 이식편수는 on-pump CABG에서 유의하게 많았으나, 수술 시간은 off-pump CABG에서 통계적으로 유의하게 짧았고, 수술 후 강심제 사용빈도는 off-pump CABG에서 유의하게 낮았다. 수술 사망은 차이가 없었으며, 수술 후 측정한 CK-MB, 중환자실 인원기간 및 호흡기 사용시간은 off-pump CABG에서 통계적으로 유의하게 낮았다. 그러나 출혈로 인한 재수술, 수술 후 심근경색증, 감염, 신부전증, 신경학적 합병증 및 수술 후 입원 기간 등은 두 군간에 통제적 유의성이 없었다. 결론: 당뇨환자에서 시행한 off-pump CABG는 on-pump CABG에 비해 심근의 손상이 적으면서 수술 후 회복이 빨랐다. 따라서 두 방법 모두 좋은 결과를 보여 주었으나, off-pump CABG가 당뇨환자에서 좀 더 효과적인 수술 방법이라고 생각한다. 그러나 전향적인 연구 등 더 많은 연구가 필요하리라 생각한다.

Purpose: In cases where nasal fractures involve frontal process of maxilla or perpendicular plate of ethmoid, 4 - 5 days of nasal packing may not provide sufficient support for avoiding displacement after packing removal. Therefore a single Kirschner - wire(K - wire) is used as an internal splint when nasal fractures involve the above two areas. Methods: Thirty five patients during the last 3 practical years were treated with a K -wire pinning according to the anatomic locations of nasal fractures. We performed a retrospective study using 13 nasal fractures out of total 35 patients. Among 13 cases, 10 patients involved frontal process of maxilla, and 3 patients were diagnosed as bilateral nasal side wall fractures accompanied with fractures of perpendicular plate of ethmoid. One patient of the last three cases had been augmented with dorsal silicone implant long before the trauma. We analyzed the anteroposterior displacement of key stone area and the width between both lateral walls by comparing immediate postoperative radiographs with 2 month follow - ups. To reduce the errors, the same measurements were taken by two different inspectors, and the mean of each inspector's measurements was compared. Patient satisfaction was analyzed using a questionnaire regarding the esthetic and functional outcomes. Results: Ten patients underwent a longitudinal K - wire fixation in submucoperiosteal plane underneath the frontal process of maxilla. And three patients underwent a transverse K - wire fixation from the one side of lateral wall to the perpendicular plate of ethmoid and to the other side of lateral wall. The mean postoperative anteroposterior displacement of the key stone area measured by two inspectors were 1.84% and 3.06%; mean narrowing of bony pyramid were 1.33% and 1.48%, respectively. Subjective satisfaction scores regarding the esthetic appearance and the maintenance of nasal shape compared with immediate post - operative state with the long term ones were not different (p>0.05). Conclusion: K - wire pinning after closed reduction is a reliable and useful method for the treatment of nasal fractures involving frontal process of maxilla or perpendicular plate of ethmoid. This is because it achieves longer intranasal support after reduction. This method also leaves conspicuous external scar, and minimal soft - tissue injury.

Absorbable plates are used widely for fixation of facial bone fractures. Compared to conventional titanium plating systems, absorbable plates have many favorable traits. They are not palpable after plate absorption, which obviates the need for plate removal. Absorbable plate-related infections are relatively uncommon at less than 5% of patients undergoing fixation of facial bone fractures. The plates are made from a mixture of poly-L-lactic acid and poly-DL-lactic acid or poly-DL-lactic acid and polyglycolic acid, and the ratio of these biodegradable polymers is used to control the longevity of the plates. Degradation rate of absorbable plate is closely related to the chance of infection. Low degradation is associated with increased accumulation of plate debris, which in turn can increase the chance of infection. Predisposing factors for absorbable plate-related infection include the presence of maxillary sinusitis, plate proximity to incision site, and use of tobacco and significant amount of alcohol. Using short screws in fixating maxillary fracture accompanied maxillary sinusitis will increase the rate of infection. Avoiding fixating plates near the incision site will also minimize infection. Close observation until complete absorption of the plate is crucial, especially those who are smokers or heavy alcoholics. The management of plate infection is varied depending on the clinical situation. Severe infections require plate removal. Wound culture and radiologic exam are essential in treatment planning.
