PURPOSE: To study the relation between the progression of glaucoma and the expression of zone beta in primary open-angle glaucoma (POAG) and normal-tension glaucoma (NTG). METHODS: One hundred thirty eyes with POAG and 62 with NTG were enrolled in this study. We classified them based on the expression of zone beta and compared their optic nerve head parameters. We looked for changes in optic nerve head parameters depending on the expression of zone beta in patients who received HRT at least 1 year previously, and whose maximal intraocular pressure (IOP) during the follow-up periods was controlled under 21 mmHg. RESULTS: In the POAG patients, the group with zone beta had significantly larger cup-to-disc (C/D) ratio, and significantly smaller neural rim area and volume, than the group without zone beta. In the NTG patients optic nerve head parameters did not show statistically significant difference. Compared with the previous values, C/D ratio, neural rim area and volume showed significant progression in POAG with zone beta, but did not show significant change in POAG without zone beta and in NTG. CONCLUSIONS: In POAG, the expression of zone beta was associated with more severe optic nerve damage and faster progression than in patients without zone beta. In NTG, the expression of zone beta was not associated with significant changes in the optic nerve shape or the progression of glaucoma.

Nodular fasciitis is rare and benign fibroblastic proliferative disease which tends to be confused microscopically with spindle cell sarcoma. It is a distinctive lesion and a very important one because of its ability to simulate a malignant process. Histopathologically, nodular fasciitis can be grouped into three subtypes based on their relation with the fascia: subcutaneous, fascial, intramuscular. We report a case of nodular fasciitis misdiagnosed as Baker's cyst in a patient with rheumatoid arthritis.

PURPOSE: To evaluate the clinical result of hydroxyapatite implantation using autologous sclera as wrapping material. METHODS: From December 2001 to February 2003, we performed 20 cases of hydroxyapatite implantation with autologous sclera as wrapping material. Eyes were enucleated for severe phthisis because evisceration could not provide adequate space for hydroxyapatite implantation or secondary hydroxyapatite implantation after prior evisceration. Postoperative complications were evaluated at postoperative 1 week, 2 weeks, 3 weeks - 1 month, 2 months, 3 months, and every 2 or 3 months thereafter. RESULTS: The mean follow up period was 12.1 +/- 4.52 months (4~18 months). During the follow up period, conjunctival erosions developed in 2 cases, which were controlled by conservative management only. No such postoperative complications as implant exposure, orbital infection, extrusion, inflammatory reaction occured. CONCLUSIONS: Autologous sclera is the suitable wrapping material of hydroxyapatite implant when enucleation is needed in primary surgery for severe phthisis, or for secondary hydroxyapatite implantation after prior evisceration surgery.

PURPOSE: To evaluate the effect of photodynamic therapy (PDT) for idiopathic subfoveal choroidal neovascularization with various imaging studies. METHODS: We retrospectively reviewed the medical records and imaging studies of 17 patients (17 eyes) who were diagnosed with idiopathic subfoveal choroidal neovascularization and treated with PDT between December 2000 and May 2003. Slit lamp examination, fluorescein angiography (FAG), indocyanine green angiography (ICGA), and optical coherence tomography (OCT) were conducted before and after PDT. RESULTS: After PDT, the mean visual acuity was improved from 0.23 (20/80) to 0.48 (20/40). On FAG, the mean size of neovascular lesion (the longest length of lesion) was slightly decreased from 2038 +/- 592 micrometer to 1872 +/- 622 micrometer after PDT. However, the change was not significant. Fluorescein dye leakage decreased or disappeared, but staining of the lesion was noted. On OCT, the macular edema disappeared, but the hyperreflective area remained after PDT. CONCLUSIONS: PDT was effective in the treatment of idiopathic choroidal neovascularization. The factors representing the therapeutic effect of PDT were visual improvement, decreased leakage on FAG, and decreased macular edema on OCT, and these three factors were significantly related to each other.

Viral hepatitis is the most important cause of acute and chronic liver disease in Korea.Particularly, hepatitis B virus (HBV) is the leading cause of liver-related mortality. Because of the nationwide vaccinations in the 1980s, hepatitis B surface antigen positive rates substantially decreased from 8% to 3%. Moreover, the introduction of potent nucleoside or nucleotide analogs led to the effective treatment of patients who had already been infected by HBV. The remaining issue has been to develop novel drugs that can cure HBV infection.Hepatitis C virus (HCV), on the other hand, is a hepatotropic virus that is parenterally transmitted. In Korea, the prevalence of HCV is estimated to be approximately 1%. Although no effective vaccine for HCV has been developed yet, highly effective and safe direct-acting antiviral therapy, which has a short treatment duration of 8 – 12 weeks, has made HCV eradication possible globally. Currently, the unsolved issue regarding HCV management is low disease awareness among patients and health care providers. Therefore, nationwide testing for anti-HCV would be a solution to identify patients infected with HCV but with no symptoms. Lastly, the Hepatitis A virus (HAV) is orally transmitted and results in acute hepatitis. In Korea, the young adult population is a high-risk group since this group is not vaccinated against HAV. More active vaccination and improved hygiene would be necessary to prevent HAV infection.

BACKGROUND: Contact immune modulating therapy with diphenylcyclopropenone (DPCP) is a topical treatment option for extensive alopecia areata (AA). Because the response to DPCP treatment varies according to the patient, and it takes several months to evaluate the clinical effectiveness of the treatment, it is necessary to identify the factors that can predict the prognosis of the disease while treating with topical DPCP. OBJECTIVE: In this study, cytokine levels in the scales of alopecic patches were investigated to identify whether they could predict response to DPCP during the early treatment period. METHODS: Scale samples were taken from the alopecic patches in eight AA patients at 1 week, 2 months, and 4 months after DPCP sensitization. The patients were divided into responders and non-responders according to the clinical responses of DPCP treatment. Interferon (IFN)-gamma, interleukin (IL)-2, IL-12 and IL-10 levels of the subjects were compared in several perspectives. RESULTS: Cytokine levels after 1 week of DPCP sensitization showed no statistically significant difference between two groups. After 4 months of treatment, IFN-gamma levels were significantly lower in responders than in non-responders. CONCLUSION: The results of this study show IFN-gamma levels in the scales of alopecic patches might possibly reflect the clinical response in AA patients treated with DPCP. However, initial cytokine levels could not predict the treatment response.

Antiphospholipid syndrome has received considerable attention due to its association with a number of serious clinical disorders including arterial and venous throboembolism, acute ischemic encephalopathy, and recurrent pregnancy loss. Thrombotic episodes are well recognized complication of Crohn's disease. Hypercoagulable state of the disease may be responsible for such thrombotic events. The association of IBD and autoimmune condition is also well recognized, even poorly understood. There may be a possible association between antiphospholipid syndrome and hypercoagulable state in Crohn's disease. Few reports on Crohn's diseases associated with antiphospholipid syndrome were documented. We experienced a 31-year-old female patient who was admitted for cerebral infaction and diagnosed of antiphospholipid syndrome with Crohn's disease.

BACKGROUND: Dysregulation of apoptosis plays an important role in carcinogenesis, tumor progression, and resistance to chemotherapy. X-linked inhibitor of apoptosis (XIAP) is considered to be the most potent caspase inhibitor of all known IAP (inhibitor of apoptosis) family members. This study was designed to assess the pattern of expression and the prognostic value of XIAP in radically resected non-small cell lung carcinoma (NSCLC) patients. METHOD: The expression of XIAP and its relationship with clinicopathologic parameters (patient age, TNM stage, TNM-pT, TNM-pN, histologic type, VEGF expression, microvessel density, PCNA index) and overall survival were analysed with formalin-fixed, paraffin-embedded blocks from eighty cases of NSCLC. In addition, the apoptotic index (AI) was also assessed. RESULTS: In a regard to histologic type, squamous cell carcinoma (SCC) showed XIAP expression in 91.3%(42/46) and adenocarcinoma (AC) in 61.8%(21/34). The difference was significant(p=0.001). There was no correlation between XIAP expression and other parameters. In the group of AC, XIAP expression showed the signifcant correlation with older age group > or = 58 years and VEGF expression(p=0.028, p=0.014, respectively). The AI in the group with or without XIAP expression were 2.5+/-4.9% and 18.5+/-28.9%, respectively(p=0.001). Both groups just aforementioned showed no significant difference in median survival time (42.5 months, 29.8 months, respectively). CONCLUSION: This study suggests that the XIAP expression in NSCLCs could have relation to inhibition of apoptosis, and show differential expression according to histologic type. However, its prognostic role during the progression of NSCLC needs to be further defined.

PURPOSE: Health-related quality of life (HRQOL) information related to radical prostatectomy (RP) is valuable for prostate cancer (PC) patients needing to make treatment decisions. We aimed to investigate HRQOL change in PC patients who underwent three types of RP (open, laparoscopic, or robotic) and compared their HRQOL with that of general population. MATERIALS AND METHODS: Patients were prospectively recruited between October 2014 and December 2015. European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire (EORTC QLQ-C30) and PC-specific module (PR25) were administered before surgery (baseline) and at postoperative 3 and 12 months. At each time point, HRQOL was compared, and a difference of 10 out of 0-100 scale was considered clinically significant. RESULTS: Among 258 screened patients, 209 (41 open, 63 laparoscopic, and 105 robotic surgeries) were included. Compared to baseline, physical, emotional, and cognitive functioning improved at 12 months. Role functioning worsened at 3 months, but recovered to baseline at 12 months. Pain, insomnia, diarrhea, and financial difficulties also significantly improved at 12 months. Most PR25 scales excluding bowel symptoms deteriorated at 3 months. Urinary symptoms and incontinence aid recovered at 12 months, whereas sexual activity and sexual function remained poor at 12 months. Clinically meaningful differences in HRQOL were not observed according to RP modalities. Compared to the general population, physical and role functioning were significantly lower at 3 months, but recovered by 12 months. Social functioning did not recover. CONCLUSION: Most HRQOL domains showed recovery within 12 months after RP, excluding sexual functioning and social functioning. Our findings may guide patients considering surgical treatment for PC.
