To verify the accuracy and reproducibility of corneal thickness measurements obtained with Orbscan (Orbtek, Inc., Salt Lake City, USA), the measurements were compared with those taken with an ultrasound pachymeter (Omega Compuscan, Storz). Central corneal thickness was measured by each method in 100 eyes of 50healthy subjects. The averages by the two methods were compared. One examiner took the measurements twice by each method in 20 eyes of 10 subjects, and intraexaminer reproducibility was evaluated. Two examiners measured the thickness in 20 eyes of 10 subjects and interexaminer reproducibility was assessed. The average corneal thickness was 550.27+/-3.56 micrometer in the Orbscan measurements and 526.62+/-3.70 micrometer in the ultrasound pachymetry: There was a statistically significant difference between the two methods. Significant difference was noticed but this showed a constant corresponding correlation with the Orbscan showing a 4.4%lower average. The intraexaminer and interexaminer reproducibility showed high reliability(Guttman split-half point<0.99). The Orbscan pachymetry is a highly reliable method and may be widely used in clinical practice.

To evaluate the reproducibility in measuring the velocities of perifoveal hyperfluorescent dots, we analyzed fluorescein angiographs of 24 eyes[24 patients]which had central serous retinopathy. Fluorescein angiography was performed with a scanning laser ophthalmoscope[SLO, Rodenstock, Mnchen, Germany]Distances between 5 moving hyperfluorescent dots in a perifoveal capillary were measured at each consecutive frame[interval 1/30 sec]. And then velocities of 5 fluorescent dots were measured with image analysis program by converting the distances to real retinal size using the Littmann's curve in 20 eyes. In the other 4 eyes, the velocities between 5 fluorescent dots of each 2 to 4 capillaries were measured. Perifoveal capillary mean blood flow velocity and standard deviation were 2.08 +/-0.36 mm/sec, and mean coefficient of variation of the velocities measured in a vessel of one patient was 12.58%. However, reliability of the velocities of 2 to 4 capillaries on the 4 eyes was relatively low. In conclusion, the measurement of velocities between perifoveal fluorescent dots with scanning laser ophthalmoscope may be a reproducible method for a perifoveal capillary. However, reliability of measuring velocities was not sufficient enough to use the velocity of one perifoveal capillary as macular blood flow.

Tamoxifen is an selective estrogen receptor antagonist widely used in the management of patients with breast cancer for more than 30 years. It was thought to act primarily through occupying the estrogen receptor sites in ER positive breast cancer cells and directly on cancer cell proper. These inhibitory effects, which have been shown to be independent of the ER, highlight new mechanism of therapeutic action of tamoxifen. The purposes of this study were to identify ER in oral carcinoma cell lines and to evaluate ER independent cytotoxic effect of tamoxifen. KB(SCC), HSC-3(SCC) and A253(ACC) cell line were used and capacity of cell proliferation, apoptosis, in vitro invasion and gelatin zymography were tested. ER expression of each cell line were detected by RT-PCR and immunocytochemistry. Dose dependent inhibition of cell proliferation and inhibition of gelatinolytic activity were observed in all oral carcinoma cell lines and significant difference of apoptotic index were observed in A253 and KB. Tamoxifen inhibited in vitro invasion in all experimental groups. ER expression was detected in KB and A253. These data suggest that tamoxifen may play a role in management of oral carcinoma by independent cytotoxic effect and more advanced research must processed confirming ER-dependent cytotoxicity.

We report a case of Aspergillus osteomyelitis of the spine in a 52-year-old female with back pain. Anteroposterior and lateral roentgenograms showed narrowing of the intervertebral disc space of T12-L1 with irregular vertebral endplates. MRI showed spondylodiscitis at T12-L1. Although tuberculous spondylitis is far more prevalent that fungal spondylitis, it is difficult to differentiate one from the other radiographically.

PURPOSE: The aim of this study is to elucidate the fundamental characteristics of the laparoscopic splenectomy and to compare the clinical outcomes and postoperative pain between the laparoscopic splenectomy and the conventional open splenectomy. METHODS: From January 2005 to January 2013, 28 patients underwent a splenectomy at Pusan National University Hospital, South Korea (PNUH). This study was a comparison of the demographic features and clinical results between the laparoscopic splenectomy (n=15) and open splenectomy (n=13). RESULTS: For the two groups of patients, the following were similar: estimated blood loss, transfusion, operative time, duration of patient-controlled analgesia, and the additional administration of painkillers. In the laparoscopic splenectomy group, the postoperative hospital stay (7.9+/-1.6 days versus 5.9+/-1.4 days, p=0.002) and the diet start time (2.7+/-0.3 days versus 1.8+/-0.8 days, p=0.003) were significantly shorter. No significant difference in postoperative pain was observed between the two groups. CONCLUSION: In this study, there was no benefit for postoperative pain in the LS group. However, the laparoscopic splenectomy has several benefits, including a shorter postoperative hospital stay and an earlier diet start time; in addition, it is feasible and safe.

PURPOSE: The purpose of this study is to compare the results of using a locking compression plate and an unlocked plate for treating proximal humeral fractures. MATERIALS AND METHODS: This study was based on 20 patients who underwent plate fixation for proximal humeral fractures out of the 87 patients with proximal humeral fractures and who were admitted from 2003 to 2007 in our hospital. Of the 20 patients, 10 were treated with a locking compression plate and the other 10 were treated with an unlocked plate. Each group was evaluated according to the humeral neck shaft angle, the period until bony union, the complications and the Constant score. The humeral neck shaft angle was based on plain x-rays taken immediately after the operation and at 6 months postoperatively. The Constant score was evaluated on the last visit to our clinic. RESULTS: There was no significant statistical difference between the two groups in terms of the neck shaft angle, the period until bony union and the Constant score. Yet, there were three cases of screw migration in the unlocked plate group. CONCLUSION: There was no significant difference between the two groups in terms of the neck shaft angle, the period until bony union and the Constant score. The locking compression plate is considered to achieve more effective fixation for proximal humerus fractures because there were less complications such as screw migration.

OBJECTIVE: We investigated the usefulness of shortening of the fetal femur length (FL) and humeral length (HL) to predict Down syndrome at the middle gestation of pregnancy in Korean subjects. METHODS: This retrospective study involved 41 fetuses with Down syndrome and 328 fetuses with normal chromosome between 14+0 and 28+6 weeks of gestation. The expected FL and HL for any biparietal diameter (BPD) was calculated based on the control group data. The odds ratios for measure to expected FL and HL in comparison between normal fetuses and Down syndrome fetuses were calculated. The sensitivities of short FL and HL to predict Down syndrome were analyzed at a fixed false positive rate of 5%. RESULTS: The lengths of femur and humerus long bone for any BPD in Down syndrome group were significantly shorter than the lengths in control group (P<0.001). A low ratio of measured to expected FL and HL increased the risk of fetal Down syndrome (P<0.001). At a fixed false positive rate of 5%, the sensitivities were 21.3% (95% confidence interval [CI] 0.698~0.852, P<0.001) in FL and 29.9% (95% CI 0.773~0.914, P<0.001) in HL. CONCLUSION: Both of short FL and HL are poor marker for Down syndrome at the middle gestation of pregnancy in Korean population though the sensitivity of HL was higher than FL.

Placenta percreta is an extremely rare and the most severe form of placental invasion, that is associated with severe maternal morbidity and mortality. We report a case of nulliparous woman who underwent 10 cycles of in vitro fertilization (IVF) without any known risk factors. We conserved her uterus by spontaneous vaginal delivery, leaving the placenta in situ, pelvic arterial embolization, and primary resection of the remaining placental tissues. This case demonstrates that repetitive IVF is a possible risk factor for placental invasion, and that conservation of the uterus can be achieved in such cases using a multidisciplinary approach.

OBJECTIVE: A novel inhibitor of apoptosis, survivin, seems to be involved in critical steps of cancer onset and progression, and associated with unfavorable clinical outcome. We investigated the expression of survivin in patients with cervical intraepithelial neoplasm and uterine cervical cancer to determine whether survivin indicates the poor prognosis or not. METHODS: The study included 14 cases of cervical intraepithelial neoplasia grade III, 53 cases of invasive uterine cervical squamous cell carcinoma. Immunohistochemical stain and western blot was performed with antihuman survivin antibody. RESULTS: Survivin was highly expressed in CIN III and cervical cancer group than normal control group (p<0.05). Significant survivin expression was noted in cancer patients with lesion size >or=4 cm, lymphovascular invasion, elevated SCC Ag. level, and nonresponse to initial therapy. As the clinical stage goes up, survivin expression had a tendency to increase but there was no statistical significance (p=0.081). No association was noted between survivin expression and survival rate (p=0.1011). CONCLUSION: This results suggest that survivin expression may provide prognostic information and could represent a possible new marker of prognosis in uterine cervical squamous cell carcinoma patients.
