Purpose: We report the first case in Korea of rapid bone formation on a subperiosteal orbital hematoma after trauma. Case summary: A 10-year-old boy who was in the intensive care unit after trauma showed proptosis and ocular movement limitation of the right eye associated with subperiosteal hematoma. On ocular examination, 3 mm of proptosis and limitation of right eye movement were observed; however, visual acuity was not decreased. At 1 month after the trauma, orbital computed tomography (CT) showed new bone formation at the margin of the hematoma border although the size of the hematoma decreased. The patient underwent hematoma and bony tissue removal using anterior orbitotomy approach. A new bone was formed between the orbital border and hematoma from the anterior orbital margin to the orbital apex. During pathological examination, woven bone tissue with fibrotic tissue was observed in the hematoma wall. One year after surgery, the patient’s proptosis and limitation of ocular movement disappeared without any evidence of new bone formation. Conclusions: Waiting for spontaneous absorption of orbital subperiosteal hematoma is usually recommended unless there is significant functional impairment. However, as in our case, new bone formation could occur during a short period of less than 1 month; imaging follow-up is necessary in patients having intensive care or showing delayed absorption of a hematoma.

Objectives : This study was designed to compare depletion and cupping therapy with cupping therapy on acute lumbosacral strain patients. Methods : This study was carried out on the 36 acute lumbosacral strain patients. We divided these patients into 2 groups. The GroupⅠ was treated with the depletion and cupping therapy and the GroupⅡ was treated with the cupping therapy. We evaluated by visual analogue scale(VAS) score after each treatment and Oswestry disability index(ODI) score before and after treatment. Result : The VAS score of GroupⅠ was statistically lower than GroupⅡ after 1st treatment. But there was no significant difference between two groups after 2st treatment. In each group, the VAS score and ODI score was statistically decreased after treatment. Conclusions : In this study, depletion and cupping therapy was more effective than cupping therapy after 1st treatment, but there was no difference between two kinds of cupping therapy after 2nd treatment on acute lumbosacral strain patients.

목적: 굴절교정술 후에 발생하는 건성안의 유병률 및 위험인자를 알아보고자 하였다. 대상과 방법: 2010년 3월부터 2014년 2월까지 삼성서울병원 안과에서 굴절교정술을 시행받은 98명, 180안의 의무기록을 후향적으로 분석하였다. 눈물막 파괴시간(tear break-up time)이 5초 미만이거나 안구표면 염색 점수(Oxford stain score)가 2점 이상인 경우를 건성안이라 정의하고, 술 후 건성안의 유병률을 알아보았다. 술 후 건성안군과 술 후 정상안군 간의 차이를 보이는 술 전 인자(인구학적 요인, 술 전 이학적 검사, 수술요인)들을 파악하고, 이를 바탕으로 술 후 건성안 발생의 위험인자들을 분석하였다. 결과: 굴절교정술 후 건성안의 유병률은 62.2%였다. 술 후 정상안군에 비해 술 후 건성안군에서 유의하게 여성의 비율이 높았고 (p=0.016), 연령이 많았으며(p=0.001), 각막 두께가 얇았다(p=0.002). 굴절교정술 후 건성안 발생의 위험 인자에 대하여 분석하였을 때, 술 전 건성안(odds ratio [OR]=9.02, confidence interval [CI]=3.8-21.4)이 수술 후 건성안 발생의 가장 강력한 위험인자로 나타났고, 연령의 증가(OR=1.06, CI=1.01-1.11) 또한 독립적인 수술 후 건성안 발생의 위험인자로 나타났다. 결론: 연령이 증가할수록, 그리고 굴절교정술 전에 건성안이 있을수록, 술 후 건성안 발생의 위험도가 더 증가하는 것으로 확인되었다. 건성안을 동반한 고령의 환자에서 굴절교정술을 시행할 경우, 굴절교정술 후 건성안 발생에 대한 주의 깊은 관찰 및 평가가 필요할 것으로 생각된다. <대한안과학회지 2017;58(7):782-787> Purpose: To assess the prevalence and the risk factors of dry eye disease after refractive surgery. Methods: A retrospective study was performed on 180 eyes of 98 patients based on medical records. Those who had tear break-up time less of than 5 seconds or had an Oxford stain scale equal to or greater than 2 were defined to have dry eye disease. We analyzed the prevalence of dry eye, compared demographic and clinical features of the dry eye group and normal group, and found risk factors of dry eye after refractive surgery. Results: The prevalence of postoperative dry eye was 62.2%. Compared to the normal eye group, the dry eye group had a significantly higher proportion of women (p = 0.016), older age (p = 0.001), and thin cornea (p = 0.002). The most significant risk factor of dry eye after refractive surgery was presence of dry eye before refractive surgery (odds ratio [OR] = 9.02, confidence interval [CI] = 3.8-21.4). Old age was also found to be an independent risk factor of dry eye after refractive surgery (OR = 1.06, CI = 1.01-1.11). Conclusions: The risk of dry eye after refractive surgery was increased in older age and preoperative dry eye disease. In order to prevent post-refractive surgery dry eye, caution should be exercised in middle aged patients with preoperative dry eye disease. J Korean Ophthalmol Soc 2017;58(7):782-787

Objectives: The purpose of this study is to document the stress of the traffic accident patients. Methods: Clinical study was carried out on 35 traffic accident patients. To measure stress score, questionnaire was done by using State-Trait Anxiety Inventory(STAI-I, II), Beck Depression Inventory(BDI), Impact of Event Scale(IES). The pain score after the traffic accident was measured by Visual Analogue Scale(VAS). Results: STAI-I, II, BDI, IES scores of the traffic accident patients were higher than normal limit and those of normal people in other studies about the stress. VAS score and duration after traffic accident showed no significant correlation with STAI-I, II, BDI, IES scores. Conclusions: Without regard to pain and duration after traffic accident, stress could be caused by traffic accident. More considerations on stress should be needed in treatment of the traffic accident patients.

Purpose Local excision may be an another option for selected patients with markedly down-staged rectal cancer after preoperative chemoradiation therapy (CRT), and proper evaluation of post-CRT tumor stage (ypT) is essential prior to local excision of these tumors. This study was designed to determine the correlations between endoscopic findings and ypT of rectal cancer. Materials and Methods In this study, 481 patients with locally advanced rectal cancer who underwent preoperative CRT followed by surgical resection between 2004 and 2013 at a single institution were evaluated retrospectively. Pathological good response (p-GR) was defined as ypT ! 1, and pathological minimal or no response (p-MR) as ypT " 2. The patients were randomly classified according to two groups, a testing (n=193) and a validation (n=288) group. Endoscopic criteria were determined from endoscopic findings and ypT in the testing group and used in classifying patients in the validation group as achieving or not achieving p-GR. Results Based on findings in the testing group, the endoscopic criteria for p-GR included scarring, telangiectasia, and erythema, whereas criteria for p-MR included nodules, ulcers, strictures, and remnant tumors. In the validation group, the kappa statistic was 0.965 (p < 0.001), and the sensitivity, specificity, positive predictive value, and negative predictive value were 0.362, 0.963, 0.654, and 0.885, respectively. Conclusion The endoscopic criteria presented are easily applicable for evaluation of ypT after preoperative CRT for rectal cancer. These criteria may be used for selection of patients for local excision of down-staged rectal tumors, because patients with p-MR could be easily ruled out.

An 8-year-old Thoroughbred mare showing anestrus for longer than 6 months with left ovarian mass was referred to Veterinary Medical Teaching Hospital of Seoul National University. For 6 months, the mare had received 2 times hormonal therapies with PGF2α and progesterone. The mare had not responded to these therapies and not shown estrous behavior. On rectal palpation, the left ovary was enlarged and contralateral ovary was small and inactive. Transrectal ultrasonographic examination of the left ovary revealed a mass composed of multiple, irregularly shaped follicles. Granulosa cell tumor (GCT) was suspected according to her history. Ovariectomy was performed through the left flank laparotomy with a standing position in a simple chute located outside of horse farm. The mass was diagnosed as GCT on histopathology. The mare was recovered without any problem and became pregnant next spring.

Purpose: In Korea, colorectal cancer (CRC) is one of the most sharply-increasing malignancies, and the National Colorectal Cancer Screening Program for persons over 50 years of age began in 2004. To determine the effectiveness of the program, comparative data regarding CRCs treated prior to 2004 must be analyzed. The present study assessed CRC status at diagnosis and treatment patterns in 2003. Methods: In 2003, 503 patients were newly diagnosed with CRC and were treated at the Center for Colorectal Cancer, National Cancer Center (NCC). Clinical data were retrospectively reviewed. Results: The 503 patients included 256 colon and 247 rectal cancer patients. Of the 256 colon cancer patients, 5 (2.0%) were diagnosed during screening colonoscopies and were successfully treated using an endoscopic mucosal resection (EMR), and 17 (6.6%) received only palliative chemotherapy because of distant metastases. Forty patients (15.6%) were treated with palliative surgery and chemotherapy, and 194 (75.8%) with curative surgery with or without adjuvant chemotherapy. Of the 247 rectal cancer patients, 9 (3.6%) were treated with an EMR, 20 (8.1%) with palliative chemotherapy with or without radiotherapy, 19 (7.7%) with palliative surgery and chemoradiotherapy, and 199 (80.6%) with curative surgery with or without chemoradiotherapy. Treatment with curative intent was possible in 199 of 256 (77.7%) colon cancer patients and in 208 of 247 (84.2%) rectal cancer patients. Conclusions: Only 12.1% of colon and 8.5% of rectal cancer patients were diagnosed early and treated without adjuvant therapies at the NCC in Korea in 2003.
