PURPOSE: We evaluated clinical results and incidence of exposures of orbital implants according to operative methods (enucleation or evisceration) and types of orbital implants. METHODS: We retrospectively reviewed the charts of 222 patients who underwent hydroxy apatite or Medpor(R) implantation after enucleation or evisceration and were followed up for more than 3 months from July, 1992 to November, 2001 at department of ophthalmology, Busan Paik hospital. RESULTS: In 222 eyes of 222 patients, who underwent hydroxyapatite and Medpor(R) implantaion, the exposure of implants occurred in 21 eyes (9.5%). In these cases, the exposure of implants occurred in 16 (12.8%) of 125 eyes with hydroxyapatite implantation and 5 (5.2%) of 97 eyes with Medpor(R) implantation. The exposure of implants occurred in 6 (7.1%) of 84 eyes after enucleation and in 15(10.8%) of 138 eyes after evisceration. The exposure of implants occurred in 12 (12.2%) of 98 eyes that used standard evisceration and in 3 (7.5%) of 40 eyes that used modified evisceration. CONCLUSIONS: The exposure of Medpor(R) implants was less than that of hydroxyapatite implants. But, it was influenced by types of orbital implants as well as operator and operative skill. There are few differences of exposure rate between the modified evisceration and enucleation.

Recently, various types of perfluorocarbon liquids are used to treat the retinal detachment due to giant tear. The authors treated 3 cases of giant retinal tear with perfluorodecalin and silicone oil. After pars plana vitrectomy, posterior retinal flap was unfolded by injection of perfluorodecalin and exchanged it for silicone oil subsequently. Silicone oil was removed after 4 weeks. Endophotocoagulation and scleral buckling were taken in all cases, and lensectomy for normal lens in 1 case. After the close observation for 6 months or more, retina was reattached successfully in 2 of 3 cases. Because of proliferative vitreoretinopathy, reinjection of silicone oil was needed in 1 case. Perfluorodecalin and silicone oil were useful materials to reattach the folded retinal flap of giant retinal tear.

In order to evaluate the accuracy of endoscopic findings in the diagnosis of gastric can the endoscopic findings of gastric lesion were compared with the macroscopic and pathologic findings of excised identical lesion. 105 operated gastric cancer paitients (advanced cancer 95 cases, early cancer 10 cases) who were diagnosed endoscopically at Pusan National University Hospital from January 1983 to August 1987 were studied. The results were as follows; 1) The accuracy of endoscopic findings were 94.7% in the advanced gastric cancer, and 45.5% in the early gastric cancer. 2) The accuracy of gross findings endoscopic and pathologic in advanced gastric cancer were 50.0% in Borrmann type I, 45.0% in Borrmann type II, 73.2% in Borrmann type III, and 66.7% in Borrmann tyye IV. 3) The accuracy of the endoscopy ia morphologic classification of advanced gastric cancer according to pathologic tumor location were 60.0% in C (upper 1/3), 43.9% in M(middle 1/3),76.3% in A (lower 1/3), 55.6% in the anterior wall, 50.0% in the posterior wall, 66.7% in the greater curavature, and 67.2% in the lesser curvature. 4) The accuracy of endoacopy in morphologic classification of gastric cancer to tumor size ware 54.5% in below 2 cm, 54.5% in from 2.1 cm to 4 cm, 65.4% in from 4.1 cm to 6.0 cm, 80% in from 6.1 cm to 8 cm, 75.0% in above 8.1 cm. 5) The accuracy of endoscopy in the morphologic classification according to the pathologic tumor stage in advanced gastric cancer were 55.6% in TNM stage I, 52.0% in TNM stage II, 65.4% in TNM stage III, and 73,7% in TNM stage IV.

OBJECTIVES: The purpose of this study was to examine the characteristics and the psychosocial factors associated to the referral to psychiatric care in the suicide attempters visiting emergency center. METHODS: We conducted a systematic chart review of 377 suicidal attempters visiting emergency center of the Korea University Ansan Hospital between January 2008 and December 2011. We gathered a data contain 20 items including psychosocial characteristics and factors related to suicide and factors related to psychiatric treatment. Multivariate logistic regression models were fitted to data to estimate the unique effects of sex, drunken status, companion, suicidal methods, place of suicide and current use of psychiatric medication on the referral to psychiatric care. RESULTS: The female gender(OR=1.63, 95% CI=0.99-2.69), suicidal attempts at home(OR=3.40, 95% I=1.21-9.56) and drunken state at visit(OR=2.34, 95% CI=1.10-5.01) are the factors that predict the risk of the non-referral of the patients to psychiatric intervention. Place of suicidal attempt was the most important factor do play a role in determining whether referral to psychiatric care will take place or not. Current use of psychiatric medication showed a trend toward significance(p=0.08, OR=1.67, 95% CI=0.95-2.95). CONCLUSIONS: These results suggest that when deciding whether to adapt or to refuse the referral to psychiatric care, the factors such as suicidal intent, lethality of suicide methods, familiar factors and alcohol may contribute onto the referral to psychiatric care. Additional research is required to investigate an association of these factors with referral to psychiatric care.

BACKGROUND: Some researchers have tried to use Tc-99m MIBI (2-methoxyisobutyl isonitril) scintigraphy to evaluate breast-cancer patients. Early reports revealed that Tc-99m MIBI breast scintigraphy was useful in distinguishing malignancies from benign masses in patients for whom mammographic evaluations were difficult. Further studies suggested that functional imaging with Tc-99m MIBI in breast cancer seemed to be correlated with the levels of P-glycoprotein (Pgp) expression and angiogenesis in cancer tissues. For that reason, we evaluated whether significant relationship actually existed between the pattern of Tc-99m MIBI uptake in tumor tissue and tumoric factors including Pgp expression and angiogenesis. METHODS: Thirty-one untreated breast-cancer patients (later pathologically proved to have had invasive ductal carcinomas) were prospectively studied by using both Tc-99m MIBI scintigraphy on and immunohistochemical analyses of angiogenesis and Pgp expression in sugically removed tumor tissues. Both lateral and anterior planar images were obtained at 10 minutes and 3 hours after intravenous injection of 740 MBq Tc-99m MIBI. The tumor-to-normal breast ratio (T/N) and the washout index (WI, early T/N minus late T/N divided by early T/N) were calculated. RESULTS: A significant correlation was found between the T/N's at early and late images (r=0.54, p=0.002 on early images; r=0.47, p=0.006 on late images). The T/N's of early images were not different among the different groups of Pgp expression (p=0.3696) while those of late images were significantly different among the groups (p=0.0276). An even more significant difference was noted in the WI's among the groups (p=0.0015). A significant negative correlation was noted between the T/N of late images and Pgp expression (p=0.0276). An even stronger correlation was found between WI and Pgp expression (r=0.668, p=0.001). CONCLUSIONS: The tumoral uptake and washout of Tc-99m MIBI can be used as a simple functional test for angiogenesis and P-glycoprotein expression in untreated breast cancer.

Transient synovitis of the hip is non-specific inflammation and self limited condition, which is most common cause of painful limping in children under 10 years of age. Ultrasonography presents some merits, simple, rapid, non-invasive, low cost, repetitive to assess soft structures in and around the hip joint compared to other diagnostic methods. We prospectively studied 32 cases of unilateral transient synovitis at OPD from Jan. 1988 to Oct. 1989 using 5-7.5 MH, probe ultrasonography. 2-times serial check up in symptomatic and asymptomatic stage about capsule thickness and bone-capsule distance in 3 different positions of the both hips were performed for comparision. The following results were obtained; 1. Boys were 25 cases (78%) and 26 cases (83%) were between 3 and 7 years old of age. 2. Bone-capsule distance in ultrasonography revealed abnormal increase in 72%. 3. External rotation position showed wider bone-capsule distance than other position. 4. Capsule thickness was 3.3mm in diseased and 3.0mm in sound, 0.3mm decrease after treatment. 5. Bone-capsule distance was 4.5mm in symptomatic stage, 2.7mm in asymptomatic stage, 1.8mm decrease after treatment in averge.
