1.Reconstruction of Isolated Medial Orbital Wall Fracture Using a Transcaruncular Approach.
Journal of the Korean Ophthalmological Society 2009;50(1):1-7
PURPOSE: We present our results in the reconstruction of medial orbital wall fractures using a transcaruncular approach. METHODS: Forty-five patients with isolated medial orbital wall fractures underwent reconstruction by transcaruncular approach in our clinic between May 2003 and October 2007, and were followed up for 6 months or more. RESULTS: Thirty-three males and 12 females were included in this study, with a mean age of 34.9 years. The most common indication for reconstruction were large sized fractures more than 50%. Operations were performed at a mean 11.9 days after trauma. Among 18 patients who had diplopia before the operation, 16 (89%) patients had symptom relief or improvement, and in the 2 patients where diplopia persisted, it did not in primary and down gaze and offered no difficulties in daily activities. Among 34 patients who had enophthalmos before the operation, most (n=30) of the patients had minimal enophthalmos not more than 2 mm, 4 patients had enophthalmos that exceeded 2 mm. CONCLUSIONS: Transcaruncular approach in reconstruction of isolated medial orbital wall fracture shows more satisfying functional and cosmetic results and can be preferred to isolated medial orbital wall fracture.

2.A Case of Gronblad-Strandberg Syndrome.
Journal of the Korean Ophthalmological Society 1986;27(4):729-734
Pseudoxanthoma elasticum associated with angioid streaks has been called rthe Gronblad-Strandberg Syndrome. A 30-year-old female patient showed circumscribed, cream-colored, crepelike, redundant plaques on neck, axillae, periumbilical area, and inguinal regions. The histopathologic findings of the skin taken from the axilla revealed extensive basophilic degeneration of the elastic tissue and calcium deposition in the middle and lower dermis. Both fundi showed irregular angioid streaks radiating from the optic disk on ophthalmoscopy, and hyperfluorescence of angioid streaks was noted with fluorescein angiography.

CD44 is a family of transmembrane glycoproteins involved in cell-cell and cell-matrix interactions. Expression of CD44 isofonns (splice variants) has been shown to be associated with poor prognosis in several human cancers. We evaluated the expression patterns of the CD44 isofortn (CD 44 splice variant v6) in infiltrating ductal carcinoma of the breast by immunohistochemical and RT-PCR method. Paraffin embedded blocks from seventy-five cases of mastectomized samples were analyzed immunohistochemically using monoclonoal antibody against CD44v6. CD44v6 was detected in fifty-seven cases (76%) of the tumor samples. Adjacent normal myoepithelial cells and ductal epithelial cells revealed focal positive reaction to CD44v6. Thirtytwo cases (80.0%) with lymph nodal metastasis revealed overexpression of CD44v6 monoclonal antibody, but twenty-five cases (71.4%) without nodal metastasis also showed positive reaction to CD44v6 monoclonal antibody, and there is no statistically significant value. Other prognostic factors of infiltrating ductal carcinoma, such as tumor size, histologic grade and hormonal receptors did not show any significant correlation with CD44v6 expression. The RT-PCR studies for 9 cases of infiltrating ductal carcinoma showed the same band patterns both in the normal and tumor tissues. From the above results, it is concluded that the expression of CD44v6 is not a valuable prognostic marker of infiltrating ductal carcinoma of breast.

4.Current Status of Renal Biopsy for Small Renal Masses.
Korean Journal of Urology 2014;55(9):568-573
Small renal masses (SRMs) are defined as radiologically enhancing renal masses of less than 4 cm in maximal diameter. The incidence of renal cell carcinoma (RCC) has increased in recent years, which is mainly due to the rise in incidental detection of localized SRMs. However, the cancer-specific mortality rate is not increasing. This discrepancy may be dependent on the indolent nature of SRMs. About 20% of SRMs are benign, and smaller masses are likely to have pathologic characteristics of low Fuhrman grade and clear cell type. In addition, SRMs are increasingly detected in elderly patients who are likely to have comorbidities and are a high-risk group for active treatment like surgery. As the information about the nature of SRMs is improved and management options for SRMs are expanded, the current role of renal mass biopsy for SRMs is also expanding. Traditionally, renal mass biopsy has not been accepted as a standard diagnostic tool in the clinical scenario because of several issues about safety and accuracy. However, current series on SRM biopsy have reported high diagnostic accuracy with rare complications. Studies of modern SRM biopsy have reported diagnostic accuracy greater than 90% with very high specificity. Also, current series have shown very rare morbid cases caused by renal mass biopsy. Currently, renal biopsy of SRMs can be recommended in most cases except when patients have imaging or clinical characteristics indicative of pathology and in cases in which conservative management is not considered.

Journal of the Korean Ophthalmological Society 1992;33(3):258-262
For the better correction of strabismus surgery, various adjustable surgical technics are performed with general or retrobulbar anesthesia. Topical anesthetics with IV analgesics (Fentany 1 citrate) and sedative (Valium) can induce adequate pain control without inhibiting extraocular muscle activities and enable intraoperative adjustment easily and conveniently without the troublesome maneuver of postoperative adjustment and accompanying risk of infection Intraoperative adjustable surgery is better than postoperative adjustable surgery because it is easier to perform due to less tissue edema, enables to avoid the risk of retrobulbar or peribulbar anesthesia, and the risk of infection. We operated 20 strabismic patients aging 10 to 48 years using the intraoperative adjustment and topical anesthetics with the good success rate 90%, within +/- 10 delta after 5 weeks follow-up.

PURPOSE: To determine whether neoadjuvant androgen deprivation therapy (NADT) improves clinical outcomes in patients with prostate cancer treated with definitive radiotherapy. MATERIALS AND METHODS: We retrospectively reviewed medical records of 201 patients with prostate cancer treated with radiotherapy between January 1991 and December 2008. Of these, 156 patients with more than 3 years of follow-up were the subjects of this study. The median duration of follow-up was 91.2 months. NADT was given in 103 patients (66%) with median duration of 3.3 months (range, 1.0 to 7.7 months). Radiation dose was escalated gradually from 64 Gy to 81 Gy using intensity-modulated radiotherapy technique. RESULTS: Biochemical relapse-free survival (BCRFS) and overall survival (OS) of all patients were 72.6% and 90.7% at 5 years, respectively. BCRFS and OS of NADT group were 79.5% and 89.8% at 5 years and those of radiotherapy alone group were 58.8% and 92.3% at 5 years, respectively. Risk group (p = 0.010) and radiation dose > or =70 Gy (p = 0.017) affected BCRFS independently. NADT was a significant prognostic factor in univariate analysis, but not in multivariate analysis (p = 0.073). Radiation dose > or =70 Gy was only an independent factor for OS (p = 0.007; hazard ratio, 0.261; 95% confidence interval, 0.071-0.963). CONCLUSION: NADT prior to definitive radiotherapy did not result in significant benefit in terms of BCRFS and OS. NADT should not be performed routinely in the era of dose-escalated radiotherapy.
