Renal dysplasia results from aberrant metanephric histogenesis caused fundamentally by a defect in inducer tissue or responding tissue. Dysplastic kidneys vary tremendously in gross and microscopic appearance but are characterized by abnormal organization and a mixed population of primitive structures, such as fetal or immature cartilage, dysplastic ducts, immature tubules, and undifferentiated mesenchyme. We report a case of unilateral multicystic renal dysplasia associated with an ipsilateral ectopic ureteral orifice entering a seminal vesicle cyst in a 33-year-old man. He was admitted due to primary infertility which had developed three years ago. The his semen analysis revealed oligospermia. No evidence of a family history of renal dysplasia was reported. Microscopic examination showed that the entire kidney was composed of cysts lined by flattened cells, dysplastic ducts and immature tubules surrounded by collars of spindle cells, primitive mesenchyme, and a few aberrantly formed glomeruli.

PURPOSE: This study was to ascertain whether there are differences in health care utilization and expenditure for Type I Medical Aid Beneficiaries before and after applying Copayment. METHODS: This study was one-group pretest posttest design study using secondary data analysis. Data for pretest group were collected from claims data of the Korea National Health Insurance Corporation and data for posttest group were collected through door to-door interviews using a structured questionnaire. A total of 1,364 subjects were sampled systematically from medical aid beneficiaries who had applied for copayment during the period from December 12, 2007 to September 25, 2008. RESULTS: There was no negative effect of copayment on accessibility to medical services, medication adherence (p=.94), and quality of life (p=.25). Some of the subjects' health behaviors even increased preferably after applying for copayment including flu prevention (p<.001), health care examination (p=.035), and cancer screening (p=.002). However, significant suppressive effects of copayment were found on outpatient hospital visiting days (p<.001) and outpatient medical expenditure (p<.001). CONCLUSION: Copayment does not seem to be a great influencing factor on beneficiaries'accessibility to medical services and their health behavior even though it has suppressive effects on outpatients' use of health care.

PURPOSE: The purpose of the study was to compare recipients' health behavior, attitude to using medicaid, medication compliance, and the changes in hospital cost and visit-day of in-patient and out-patient care between tele-care regions (TCR) and general care regions (GCR) in Korean medicaid. METHOD: The design of the study was ex-post facto comparing recipients in TCR and GCR. The sample included 625 persons in TCR and 410 persons in GCR. To collect materials, the case manager interviewed recipients of medicaid and filled out questionnaires which were analyzed through SAS/PC 9.1. RESULTS: In studying health behavior and medication, compliance was not significant. However, the attitude to using medicaid was significantly more positive in TCR than in GCR. In out-patients, the change of hospital visit-day was not significant between TCR and GCR, but TCR showed a reduction in hospital cost compared to GCR. For in-patient recipients, GCR showed a greater reduction in changes in hospital cost and visit-day compared to TCR. CONCLUSIONS: The results of the study show that attitudes to using medicaid via telephone are positive and results are more effective than hospital visit consultation, and the cost of out-patient care could be reduced.

With an aging population, osteoporotic vertebral collapse is an increasingly common condition. This compression fractures has been considered a benign entity, quite responsive to conservative treatment. In a rare patients, however, a major neurologic complication and painful kyphosis despite conservative treatment can develop. Therefore, the purpose of this present study is to analyze the surgical results of 14 patients with severe back pain, an increasing kyphosis and neurologic deficits caused hy osteoporotic vertebral collapse following minor trauma, who were treated surgically. Presenting signs and symptoms included severe back pain with progression of kyphosis in 6 patients and increasing neural deficit in 8 patients. Of 14 patients, eight patients had an intravertebral cleft sign (vacuum sign). Indications for surgery included increasing kyphotic deformity, intractable pain, or increasing neurologic deficit. There was no correlation between intravertebral cleft sign and neurologic deficit. However, patients who had intravertebral cleft sign had not well respond to conservative treatment. As treatments, combined anterior and posterior fusion in 8, anterior fusion in 4, posterior instrumentation, and wide decompressive laminectomry in one patient, respectively, were carried out. The final correction of the deformity averaged 0.3 degrees. Therefore. correction of kyphosis was not favorably maintained because of variable surgical methods, and sinking of graft bone or instrumentation into the osteoporotic vertebral bodies. However, pain was reduced significantly in all patients. In addition neurological symptoms improved in 7 patients. One patient underwent reoperation with nnterior inierbody tusion together with anterior instrument because of an increasing kyphosis, neurologic. iymptoms and scvcre hack pain following wide decompressive laminectomy. There was no complication relatecl to instruments. The authors strongly helieved that surgical intervention has highly satisfactory results in patients who have intravertehral cleft sign with persistent back pain despite conservative treatment, and proressive or persistent neurologic deficits following osteoporotic vertebral collapse.

Pigmented neurofibroma, a variant of neurofibroma, has rarely been observed in patients with or without neurofibromatosis. Pigmented neurofibroma is characterized histologically by the coexistence of scattered melanin-laden cells and benign spindle cells with neural differentiation. We report a case of pigmented neurofibroma in a 22-year-old female patient.

BACKGROUND: The claudins are a family of transmembrane proteins associated with tight junctions and they are critical for maintaining cell-to-cell adhesion in sheets of epithelial cells. However, their role in the progression of cancer remains largely unexplored. The aims of this study were to evaluate the expression patterns of claudin-1 and -4 in benign lesions and invasive ductal carcinomas (IDC) of the breast, and relationships between the expression of these markers and the clinicopathological characteristics in IDC patients. METHODS: We examined the claudin-1 and -4 protein expressions by performing immunohistochemical stainings in 54 benign lesions and 120 IDCs via the tissue microarray method. We evaluated the correlation between the expression of these markers and the clinicopathological characteristics of IDC. RESULTS: The expressions of claudin-1 (p=0.099) and -4 (p=0.000) were up-regulated in IDCs as compared with benign lesions. The claudin-1 expression correlated with the loss of estrogen receptor (p=0.036) and progesterone receptor (p=0.011). The claudin-4 expression correlated with lymph node metastasis (p=0.043), the nuclear grade (p=0.030), the histologic grade (p=0.007), and the loss of estrogen receptor (p=0.001) and progesterone receptor (p= 0.029). CONCLUSIONS: These results suggest that claudin-1 and -4 may play a significant role in the carcinogenesis of IDC of the breast and these may represent novel markers for this disease.

9.Comparison of Retinal Nerve Fiber Layer Thickness between Stratus and Spectralis OCT.
Korean Journal of Ophthalmology 2011;25(3):166-173
PURPOSE: To compare the peripapillary retinal nerve fiber layer (RNFL) thickness of normal patients and those with various glaucoma diseases by time domain (Stratus) and spectral domain (Spectralis) optical coherence tomography (OCT). METHODS: The RNFL thickness as measured by the Stratus and Spectral OCT was compared (paired t-test). The relationship and agreement of RNFL thickness between the two OCT modalities were evaluated by Pearson correlation, Bland-Altman plot, and area under the receiver operating characteristic curve. RESULTS: Two-hundred seventeen eyes of 217 patients, including twenty-four normal eyes, ninety-one glaucoma suspects, seventy-six normal tension glaucoma cases, and twenty-six primary open angle glaucoma cases (POAG) were analyzed. The peripapillary RNFL thicknesses as measured by Stratus OCT were significantly greater than those measured by Spectralis OCT. However, in quadrant comparisons, the temporal RNFL thickness obtained using Stratus OCT were significantly less than those obtained using Spectralis OCT. Correlations between RNFL parameters were strong (Pearson correlation coefficient for mean RNFL thickness = 0.88); a high degree of correlation was found in the POAG group. Bland-Altman plotting demonstrated that agreement in the temporal quadrant was greater than any other quadrant. CONCLUSIONS: Both OCT systems were highly correlated and demonstrated strong agreement. However, absolute measurements of peripapillary RNFL thickness differed between Stratus OCT and Spectralis OCT. Thus, measurements with these instruments should not be considered interchangeable. The temporal quadrant was the only sector where RNFL thickness as measured by Spectralis OCT was greater than by Stratus OCT; this demonstrated greater agreement than other sectors.
