The aim of this study was to examine the effect of phase I cardiac rehabilitation program (CRP) on physical capacity in patients with coronary artery bypass graft (CABG). Eighty seven patients who underwent CABG in our hospital were enrolled on the study. Among them, excluding 17 during the study, the results of 70 patients were included in the final data. Subjects were classified into two groups according to the participation in the phase I CRP; participation group (n=35) and non-participation group (n=35). The CR was executed for the participation group until patients' discharge. The variables including resting heart rate (RHR), oxygen saturation, walking distance in 6 minutes, and forced expiration amount were measured at initial phase, discharge and follow-up at 1 month after discharge. From the data, descriptive statistics (mean, standard deviation) were calculated, and differences in each variable before, during, after the treatment and between groups were tested using repeated measure analysis of variance using SPSS ver. 18.0 statistics program for Window. For the effects and results with a statistical significance, post-hoc test was made using t-test. There was statistically significant difference (p<0.05) in the RHR and the walking distance in 6 minutes. While there was no significant difference in the oxygen saturation and the maximum expiration amount. As conclusion, the Phase I CRP after CABG showed a effect on the significant improvement of physical capacity by decreasing the RHR and increasing the walking distance in 6 minutes, exerting a positive influence on the recovery after the CABG operation.

PURPOSE: To report a case of epidemic keratoconjunctivitis complicated by Alcaligenes xylosoxidans. METHODS: A 37-year-old man suffered epidemic keratoconjunctivitis in both eyes. Eleven days later, he developed a corneal ulcer in his left eye. Bacterial staining, culture, and antibiotics sensitivity test were performed from a corneal scrape. RESULTS: The cultures revealed a growth of Alcaligenes xylosoxidans, and the patient was treated with ceftazidime and levofloxacin, based on the sensitivity test results. After 21 days of treatment, the infection was resolved with mild scaring and final vision in the left eye of 20/20. CONCLUSIONS: Alcaligenes xylosoxidans should be considered a rare but potential pathogen able to produce corneal ulcer complication in epidemic keratoconjunctivitis.

3.Subretinal Inflammatory Myofibroblastic Tumor: Clinicopathological Findings.
Korean Journal of Ophthalmology 2005;19(3):235-238
PURPOSE: To present a case of inflammatory myofibroblastic tumor which was manifested as an idiopathic subretinal mass without underlying pathology. METHODS: The subretinal mass was surgically excised and evaluated histopathologically. Fluorescein angiography and optical coherence tomography were performed pre- and post-operatively. RESULTS: The mass was histologically composed of lymphoplasma cell infiltration and fibrous proliferation without microorganisms or malignant cells. Immunohistochemistry for smooth muscle actin revealed myofibroblasts as a major cellular component. Preoperative optical coherent tomography showed that the lesion was contiguous to the retina while inducing foveal detachment. Postoperatively, the fovea was attached with visual recovery, and the subretinal lesion did not recur during the follow up. CONCLUSIONS: Inflammatory myofibroblastic tumors may be included in the differential diagnoses of subretinal masses.

4.The Effect of Latanoprost on Intraocular Pressure during 12 Months of Treatment for Normal-tension Glaucoma.
Korean Journal of Ophthalmology 2005;19(4):297-301
PURPOSE: To evaluate the intraocular pressure (IOP) -lowering efficacy of latanoprost in normal-tension glaucoma (NTG). METHODS: One-hundred and seventeen eyes of 63 NTG patients treated with 0.005% latanoprost once a day were enrolled in this study. Of these, 85 eyes of 47 patients were treated for 12 months. Mean IOPs were analyzed, and the mean IOP reductions from the untreated baseline were assessed after two weeks and after 1, 3, 6, 9, and 12 months of treatment. RESULTS: The mean untreated baseline IOP was 15.0+/-2.7 mmHg. After two weeks of latanoprost treatment, the mean IOP reduction from the baseline value was 2.6+/-0.2 mmHg (17.3%, p< 0.05), and after 6 and 12 months, the reduction was 2.4+/-0.2 mmHg (16.0%, p< 0.05) and 2.4+/-0.2 mmHg (16.0%, p< 0.05), respectively. Patients with a baseline IOP of > or=15 mmHg achieved significantly higher IOP reductions than those with a baseline IOP of < 15 mmHg at all follow-ups (p< 0.05). CONCLUSIONS: Latanoprost was found to be well tolerated and to significantly reduce IOP in NTG patients.

Journal of the Korean Surgical Society 2004;66(6):478-483
PURPOSE: To analysis the chronological changes of surgical strategy for early gastric cancer (EGC) in our hospital over a 10-year period. METHODS: From November 1993 to August 2003, we experienced 201 patients with EGC at Ewha Womans University Mokdong Hospital. The medical and pathologic records of these patients were reviewed retrospectively. The patients were categorized into three groups in chronological order: P1 (1993~1996), P2 (1997~2000), and P3 (2001~2003). The clinicopathological characteristics and treatment modalities among these three groups were compared. RESULTS: Of the 683 gastric cancer patients, 201 patients (29.7%) were pathologically confirmed to have EGC. The proportion of EGC gradually increased in chronological order: 19.2% in P1, 33.2% in P2 and 32.9% in P3. There were no significant differences in clinicopathological characteristics among three groups, including age, sex, location, size, gross type, histology, depth of invasion, and lymph node metastasis. Open surgery was performed in 134 patients, laparoscopic surgery in 52 and endoscopic mucosal resection (EMR) in 15. The proportion of minimally invasive surgery such as EMR, laparoscopic wedge resection, laparoscopy- assisted distal gastrectomy (LADG), and hand-assisted laparoscopic surgery (HALS) increased in chronological order: 0% in P1, 22.4% in P2 and 58.5% in P3. The postoperative mortality was 1.49% (3/201): 2 cases after open surgery, and 1 case after laparoscopic wedge resection. One case after open conventional surgery recurred. There were no significant difference in postoperative complication, postoperative mortality and survival rate among the three groups. Overall 5-year survival rate was 95.4%. CONCLUSION: The proportion of minimally invasive surgery increased during a 10-year period in our hospital. However, there were no significant differences in postoperative complication, postoperative mortality, recurrence rate, and survival rate among three chronological groups.

PURPOSE: To evaluate corneal biomechanical properties in eyes that had previously undergone penetrating keratoplasty (PK) using the ocular response analyzer (ORA). METHODS: We recruited 26 patients who had received unilateral PK. Corneal hysteresis (CH), corneal resistance factor (CRF), Goldmann-correlated intraocular pressure (IOPg), and cornea-compensated intraocular pressure (IOPcc) were measured with the ORA and were compared to the measurements from the contralateral eyes that did not undergo PK. RESULTS: The CH was 8.95+/-2.59 mmHg in eyes that underwent PK and 9.78+/-1.45 mmHg in the contralateral eyes that did not undergo PK (p=0.077). The CRF was 10.26+/-2.64 mmHg in post-PK eyes and 9.75+/-1.45 mmHg in the contralateral eyes (p=0.509), and the CH-CRF was significantly smaller in post-PK eyes (-1.31+/-2.32 mmHg in post-PK eyes vs. 0.03+/-0.88 mmHg in fellow eyes, p=0.016). The IOPg and IOPcc were significantly higher in the PK group than they were in the control group. The IOPcc's were 20.81+/-7.81 mmHg and 16.27+/-2.49 mmHg in post-PK and control eyes, respectively (p=0.011); and the IOPg's were 19.22+/-7.34 mmHg and 15.07+/-3.03 mmHg in post-PK and control eyes, respectively (p=0.019). The IOPcc-g's were 1.59+/-2.81 mmHg and 1.21+/-1.30 mmHg in post-PK and control eyes, respectively (p=0.412), and the central corneal thickness (CCT)'s were 489.11+/-90.60 microm and 556.24+/-42.84 microm in post-PK and control eyes, respectively (p=0.068). CONCLUSIONS: Following PK, CH tended to decrease while CRF tended to increase, significantly decreasing CH-CRF. A significantly higher intraocular pressure and a thinner CCT following PK may have contributed to the observed changes in these corneal biomechanical parameters.

BACKGROUND: Myocardial contrast two-dimensional echocardiography(MC-2DE) has been known to have the real time capabilities for repeat in vivo assessment of ischemic risk areas and for evaluation of the myocardial perfusion. The aims of this investigation are (1) to evaluate the feasibility of MC-2DE for the delineation and quantitation of the area at risk. (2) to determine the relationship between the extent of the echocontrast defect area(EDA) during reperfusion and the size of myocardial infarction as determined by post-mortem tissue examination, and (3) to observe serial changes in the time echo-intensity characteristics of MC-2DE during coronary occlusion and reperfusion. METHODS: Myocardial contrast echocardiographic images were made by injecting bolus 5mL of two-syringe-agitated mixture of sodium meglumine ioxaglate(Hexabrix(R)) and normal saline(2 : 3 by volume) into the aortic root before and during coronary occlusion of the left anterior descending coronary artery, distal to the first diagonal branch and during reperfusion on eight open-chest dogs. Two-dimensional echocardiographic short axis views were obtained at four anatomic levels : the apex, the low papillary muscle, the high papillary muscle and the mitral valve. The changes in EDA and echo-intensity with its wash-out half time(WHT) at the high papillary muscle level during coronary occlusion and reperfusion were measured every 15 minutes. The total EDA was measured by planimetry at 3 minutes after coronary occlusion and at 60 minutes after reperfusion. Evans blue or methylene blue were used for the measurement of the anatomic area at risk and triphenyl-tetrazolium chloride(TTC) for the measurement of the infarct area. RESULTS: The EDA measured 30 minutes after coronary occlusion(19.6%) was smaller than that at 3 minutes after coronary occlusion(24.0%, p<0.01). Then EDA at 3 minutes occlusion was strongly predictive of the anatomic extent of area at risk(EDA=0.48 Area at risk+16.95, r=0.84, p<0.05). The EDA at 60 minutes after reperfusion, which showed an irregular margin and was located within the subendocardium of the area at risk, also correlated well with the infarct area(IA)(EDA=0.78 IA+3.32, r=0.82, p=0.09). The peak echo-intensity in the ischemic area during coronary occlusion was significantly low(14.2+/-6.5 vs 73.8+/-31.7 in the non-ischemic area, p<0.01) and the WHT was delayed more in the ischemic area than in the non-ischemic area(23.2+/-2.8 sec vs 8.1+/-3.3sec, p<0.01). During the period of reperfusion, WHT in the previously ischemic area was markedly delayed compared to that in the non-ischemic area (p<0.01), although the peak echo-intensity in the ischemic area at 3 minutes after reperfusion increased modestly compared to that in the non-ischemic area(80.9+/-22.8 vs 72.7+/-8.4), suggesting the impairment in the transit of microbubbles is probably due to microvascular damage after reperfusion. There were no adverse hemodynamic or electrocardiographic effects after injection of the contrast agent. CONCLUSIONS: These findings suggest that myocardial contrast echocardiography was useful as a non-invasive technique, first, to delineate the area at risk in vivo during coronary occlusion and, after reperfusion, the infarct area, and secondly, to evaluate indirectly the state of myocardial perfusion during coronary occlusion and reperfusion.

PURPOSE: This study aimed to evaluate whether prophylactic extended-field pelvic radiotherapy (EF-PRT) yields better results than standard whole pelvic radiotherapy (WPRT) in patients with pelvic lymph node-positive cervical cancer treated with concurrent chemoradiotherapy (CCRT). MATERIALS AND METHODS: A total of 126 cases of stage IB-IVA cervical cancer that had pelvic lymph node involvement in magnetic resonance imaging and were treated with CCRT between 2000 and 2016 were reviewed. None of the patients had paraaortic lymph node (PALN) metastases. The patients were classified to two groups, namely, those treated with EF-PRT, including prophylactic para-aortic radiotherapy, and those treated only with WPRT. The median dose to the PALN area in patients treated with EF-PRT was 45 Gy. All patients received concurrent cisplatin-based chemotherapy. RESULTS: Overall, 52 and 74 patients underwent EF-PRT and WPRT, respectively. Patient characteristics and irradiated dose were not significantly different, except the dose to the para-aortic area, between the two groups. The median follow-up period was 75.5 months (range, 5 to 195 months). The 10-year cumulative recurrence rate of PALN for EF-PRT vs. WPRT was 6.9% and 10.1% (p = 0.421), respectively. The 10-year disease-free survival and overall survival for EF-PRT vs. WPRT were 69.7% vs. 66.1% (p = 0.748) and 71.7% vs. 72.3% (p = 0.845), respectively. Acute gastrointestinal complications were significantly higher in EF-PRT (n = 21; 40.4%) than WPRT (n = 26; 35.1%) (p = 0.046). Late toxicities were not significantly different in both groups. CONCLUSION: In this study, prophylactic radiotherapy for PALN does not have an additional benefit in patients with pelvic lymph node-positive cervical cancer treated with CCRT.

PURPOSE: We investigated whether infantile vulvar abscesses are predictable features of rectovestibular fistula with a normal anus. MATERIALS AND METHODS: A retrospective analysis of five infants with vulvar abscesses and rectovestibular fistulae with normal anuses was performed. RESULTS: Four cases had a left vulvar abscess, and in one case the vulvar abscess was on the right side. All caregivers reported passage of stool from the vagina. The fistulae were almost uniformly located from the vestibule to the rectum above the anal dentate line, observable by visual inspection and probing under anesthesia. The first two cases were treated with division and closure of the fistulae after a diverting loop colostomy, and the remaining three cases with fistulotomy and curettage. There was no recurrence during the median follow-up period of 38 months. CONCLUSION: This unique rectovestibular fistula should be suspected in female infants with vulvar abscesses, especially when parents report passage of stool from the vagina. Fistulotomy and curettage may be an initial treatment and effective as a temporary diverting colostomy and delayed repair of the fistula.

PURPOSE: To compare the accuracy of intraocular lens (IOL) power calculation using conventional regression formulae or the American Society of Cataract and Refractive Surgery (ASCRS) IOL power calculator for previous corneal refractive surgery. METHODS: We retrospectively reviewed 96 eyes from 68 patients that had undergone cataract surgery after keratorefractive surgeries. We calculated the formula with two approaches: IOL powers using the ASCRS IOL power calculator and IOL powers using conventional formulae with previous refractive data (Camellin, Jarade, Savini, and clinical history method) or without prior data (0, 2 and, 4 mm total mean power in topography, Wang-Koch-Maloney, Shammas, Seitz, and Maloney). Two conventional IOL formulae (the SRK/T and the Hoffer Q) were calculated with the single K and double K methods. Mean arithmetic refractive error and mean absolute error were calculated at the first postoperative month. RESULTS: In conventional formulae, the Jarade method or the Seitz method, applied in the Hoffer Q formula with the single K or double K method, have the lowest prediction errors. The least prediction error was found in the Shammas-PL method in the ASCRS group. There was no statistically significant difference between the 10 lowest mean absolute error conventional methods, the Shammas-PL method and the Barrett True-K method calculated with using the ASCRS calculator, without using preoperative data. CONCLUSIONS: The Shammas-PL formula and the Barrett True-K formula, calculated with the ASCRS calculator, without using history, were methods comparable to the 10 most accurate conventional formulae. Other methods using the ASCRS calculator show a myopic tendency.
