PURPOSE: To examine the results of macular hole surgery using pars plana vitrectomy (PPV), triamcinolone-assisted peeling of the internal limiting membrane (ILM), and intravitreous air in idiopathic stage 2 and 3 macular holes. METHODS: Thirteen eyes of 13 consecutive patients with idiopathic macular hole underwent a PPV with triamcinolone-assisted ILM peeling and intravitreous air tamponade. An air-fluid exchange was performed and the patient was asked to maintain a face-down position at home for 4 days. The follow-up period was 6 months or more in all cases. If a significant cataract was present before surgery, a combined phacoemulsification with posterior chamber lens implantation was performed at the time of the macular hole surgery. The closure of the macular hole was determined by biomicroscopy and Optical Coherence Tomography (OCT). RESULTS: The idiopathic macular hole was closed after the primary operation in all 13 patients. The postoperative visual acuities (0.1 to 0.9) significantly improved from the preoperative visual acuities (0.02 to 0.4) in all eyes. There was no recurrence of the macular hole and there were no adverse effects of the intraoperative use of triamcinolone and ILM peeling during the follow-up period. CONCLUSIONS: This study suggests that triamcinolone-assisted ILM peeling with intravitreous air may be an effective technique for stage 2 and 3 macular holes. This procedure could reduce the face-down position time and improve early visual rehabilitation by using air instead of long-acting gas tamponade.

Purpose:
This study aimed to investigate the abnormal and borderline ABIs for predicting coronary re-intervention and mortality in patients with coronary artery disease (CAD).
Materials and Methods:
Data from a previous study were obtained and used to investigate the prevalence of peripheral arterial disease among Korean patients with CAD (n=285) in 2010. All patients underwent follow-up coronary angiography as scheduled (asymptomatic: 2-, 5-, and 7-month intervals) or as clinically indicated (symptomatic).
Results:
In total, 33 patients had an abnormal ABI (ab-ABI: <1.0 or >1.4), and 252 had a normal ABI (nl-ABI: 1.0≤ABI≤1.4). The mean follow-up was 47 months. The mortality was significantly higher in the ab-ABI group than in the nl-ABI group (18.2% vs. 6.7%, P=0.0233). MACEs were significantly more common in the ab-ABI group (60.6% vs. 34.5%, P=0. 0036). Moreover, the ab-ABI group had a greater CAD progression than the nl-ABI group (48.5% vs. 31.3%, P=0.0496). The incidence of clinically indicated coronary re-intervention was significantly higher in the ab-ABI group than in the nl-ABI group (33.3% vs. 13.1%, P=0.0025). After adjusting for age, diabetes, dyslipidemia, dialysis, smoking, and obesity, the incidence of clinically indicated re-intervention was significantly higher in the ab-ABI group than in the nl-ABI group (HR, 2.80; 95% CI, 1.24 to 6.34).
Conclusion
Abnormal and borderline ABI significantly increased the incidence of clinically indicated coronary revascularization and all-cause mortality during a 4-year follow-up among patients with CAD. Hence, ABI could be used to stratify extremely high-risk patients with CAD who may require aggressive surveillance or treatment.

Between 1 and 2% of benign cystic teratomas undergo malignant transformation. This occurs most frequently in postmenopausal women, who account for only 10% of benign cystic teratoma. A wide variety of neoplasms arise in the mature tissues of otherwise benign teratomas. Of the malignancies arising in teratomas, squamous carcinoma is the most common (83%) with sarcomas accounting for 7%, adenocarcinoma and carcinoid tumors make up most of the others. The presentation in Stage I disease does not differ from that of benign cystic teratoma, except that ascites is occasionally present. In the more advanced neoplasms, the symptoms are those of epithelial ovarian cancer of the same stage. Differential diagnosis between squamous cell carcinoma and benign mature teratoma is difficult but seems to be related to age, size, serum tumor marker (SCC, CA125, CEA). Prognosis of squamous cell carcinoma in mature cystic teratoma was reported much poorer than other epithelial ovarian cancers In the early stages, treatment is possible through surgical intervention alone, but when advanced, 5 year survival rate shows less than 15 percent. We experienced two cases of squamous cell carcinoma of ovary arising in mature teratoma and present with a brief review of literature.

In case of class II malocclusion, mandible has morphological characteristics such as size and position. To investigate morphological characteristics of mandible, most study has been done in indirect measurement using cephalogram. Recently, it is possible to measure directly Three dimensional skeletal model reconstructed from computed tomography images. This study aimed to know characteristics of mandible in class II malocclusion, analyzing Three dimensional mandible models of class I and II malocclusion which are acquired from computed tomography images of 80 cadavers. In open bite type of class II malocclusion, the size of mandible had no difference from class I malocclusion but the sagittal ramus angle and condylar angle were smaller 3 degree than class I. These findings inform that the ramus and condylar process of open bite type of class II malocclusion stand more erectly than class I and then the mandible is placed posteriorly. In deep bite type of class II malocclusion, the length of mandible was shorter 4 mm and, the sagittal ramus angle and condylar angle were larger 5 degree than class I. These findings, short length of mandible and more lying ramus and condylar process, make the mandible in the feature of deep bite of class II malocclusion. In comparison of past issued articles which used cehpalometry mainly, the values of measurements agree partially. It is the differences of measuring points and methods to make inconsistency between indirect measurement like cephalometric study and 3 dimensionally direct measurement like this study. To increase accuracy of Three dimensionally direct measurement, standardization of measuring points and method for the measurement is required.

OBJECTIVE: Our purpose was to investigate lipid peroxide levels, total peroxyl radical-trapping antioxidative parameter (TRAP) values, and antioxidant vitamin levels in placental tissues of women with preeclampsia and to evaluate their roles in the pathophysiology of preeclampsia. STUDY DESIGN: Samples of placental tissue homogenates were obtained from 23 normal and 18 preeclamptic women between 33 and 40 weeks gestation. TNF-alpha was assayed by an enzyme-linked immunoassay. Lipid peroxide levels measured by thiobarbituric acid reaction. The TRAP values were measured by modified Wayners method. Ascorbic acid, uric acid, retinol, alpha-tocopherol, and gamma-tocopherol were measured by high performance liquid chromatography (HPLC) CoulArray detector. RESULTS: TNF-alpha levels in placental tissue homogenates of women with preeclampsia were significantly higher than that of women with preeclampsia (21.4+/-3.39 vs. 10.3+/-1.06 pg/ml, p<0.05). Lipid peroxide levels in placental tissue homogenates of women with preeclampsia were significantly higher than that of women with preeclampsia (6.65+/-0.57 vs. 4.98+/-0.37 nmol/mg protein, p<0.05). TRAP values in placental tissue homogenates of women with preeclampsia were significantly lower than that of women with normal pregnancy (0.24+/-0.02 vs. 0.31+/-0.03 mM, p<0.05). Ascorbic acid levels in placental tissue homogenates of women with preeclampsia were significantly lower than that of women with normal pregnancy (217.0+/-21.0 vs. 333.3+/-32.8 nmol/ml, p<0.05). CONCLUSION: The above results suggest that increased oxidative stress in placenta is involved in the pathophysiology of preeclampsia and ascorbic acid may act as an important preventive factor in the development of preeclampsia.

OBJECTIVE:To investigate interleukin-6 (IL-6), C-reactive protein (CRP), and lipid peroxide levels in the umbilical venous plasma of preterm birth with or without histologic chorioamnionitis and to evaluate their roles in the pathophysiology in preterm labor and perinatal outcome. METHODS:This cohort study included 66 cases of preterm delivery with preterm labor and intact membranes (PTL) (n=39) and preterm premature rupture of membranes (PPROM) (n=27). The umbilical venous blood samples were collected at the time of delivery. IL-6, CRP, and lipid peroxide levels were measured by ELISA Kit, latex agglutination assay, and thiobarbituric acid reaction. Histologic chorioamnionitis was diagnosed by the presence of neutrophil infiltration into the subamnionic space. RESULTS:The prevalence of histologic chorioamnionitis was significantly higher in PPROM (59.3 %, 16/27) than in PTL (20.5%, 8/39). IL-6, CRP, and lipid peroxide levels in the umbilical venous plasma of histologic chorioamnionitis were significantly higher than those without histologic chorioamnionitis. IL-6, CRP, and lipid peroxide levels in the umbilical venous plasma of PTL with histologic chorioamnionitis were significantly higher than those of PTL without histologic chorioamnionitis. CRP levels in the umbilical venous plasma of PPROM with histologic chorioamnionitis were significantly higher than those of PPROM without histologic chorioamnionitis. Three suspected neonatal sepsis patients have increased IL-6 and lipid peroxide levels in the umbilical venous plasma compared with patients without neonatal sepsis. IL-6 levels in the umbilical venous plasma of histologic funisitis were significantly higher than those without funisitis. CONCLUSION:Preterm birth with chorioamnionitis is associated with an increased level of IL-6, CRP, and lipid peroxide in umbilical venous blood. Preterm birth with chorioamnionitis may have an effect on perinatal outcome.

Renal transplantation is the optimal treatment for end stage renal disease and it has been improved through the development of operative methods and immunosuppressants. However some patients must receive dialysis or undergo retransplantation after a loss of the primary graft due to rejection or other causes. Recently the frequency of retransplantation has begun to increase gradually. Some articles have reported that retransplantation results do not significantly differ in comparison with initial transplantation results when living related donor kidneys are used. Our study focused on the outcome of 445 first transplantation and 12 retransplantation cases. The sex distribution of retransplanted patients was 11 male and 1 female. The mean age (yrs) for recipients was 32.3 at the first transplantation and 39.1 at the retransplantation. The underlying causes of end stage renal disease were presumed to be chronic glomerulonephritis in all retransplantion patients; the mean duration of graft survival (mo) for first transplantation was 77.92. The causes of previous graft failure were as follows: 10 due to chronic rejection, 1 due to recurrent glomerulonephritis, 1 resulted from a graft rupture due to a motorcar accident. The interval (mo) between graft failure and retransplantation averaged 6.7 and 9 out of 12 patients underwent regrafting within 1 year of their previous graft loss. Recipient-donor relationships in first transplantations were as follows: 9 were living related and 3 were living non-related. Recipient-donor relationships in second transplantations were as follows: 4 were living related and 8 were living non-related. Acute rejection within 1 month of transplantation occurred in 4 primary transplantation patients and 2 retransplantation patients. The incidence of acute rejection within 1 month was as follows: 23% of 445 first renal transplantation patients, 16.7% of 12 second transplantation patients. The 1 year and 2 year graft survival rate was 100% and the mean survival duration (mo) was 33 for retransp
