PURPOSE: The aim of this study is to better understand the pattern and nature of reverse redistribution (RR) in myocardial perfusion imaging. MATERIALS AND METHODS: In consecutive 20 acute myocardial infarction (MI) patients, frequency of RR was correlated with that of subendocardial MI that was detected by myocardial contrast echocardiography (MCE). RR was judged to be present when there was more than one grade of worsening in perfusion at 24 hr delayed images compared with the initial rest images. MCE evaluated the significant lack of opacification in the subendocardial myocardium relative to the subepi-cardial myocardium to suggest the subendocardial MI. Kendall's nonparametric correlation coefficiency was calculated. RESULTS: Concordant cases were 15 of 20 (75%) and correlation was statistically significant (p=0.0285). CONCLUSION: Our results suggested that RR was correlated with MCE-detected nontransmural MI.

PURPOSE: To investigate the effect of steroid treatment (intravenous injection, oral) in patients with non-arteritic anterior ischemic optic neuropathy (NAION). METHODS: From January, 2005 to December, 2016, 41 patients who were diagnosed with NAION and observed for more than 6 months were included in this study. The treatment was decided based on patient's choice after explaining the advantages and disadvantages of steroid therapy. The patients were divided into three groups (intravenous steroid injection, oral steroid, no treatment). Initial visual acuity, final visual acuity, degree of visual field defect, fluorescein angiography, visual evoked potential and brain magnetic resonance imaging were analyzed by chart review. RESULTS: The chief complaints of the 41 NAION patients at the first visit were decreased visual acuity (n = 24), visual field defect (n = 10), no symptoms (n = 4), diplopia (n = 2), and floaters (n = 1). The distribution of the patients according to steroid administration method was 15 patients with intravenous steroid injection, 14 patients with oral steroid and 12 patients with no treatment. The improvement in visual acuity was greatest in intravenous steroid injection (87%), oral steroid (43%) and no treatment (33%) in that order. CONCLUSIONS: In a retrospective comparison of treatment effects after explaining the advantages and disadvantages of steroid therapy in patients with NAION, the intravenous steroid injection group showed 87% improvement in visual acuity and an odds ratio of 5.5 (95% confidence interval [CI] 1.05–28.88, p-value 0.04), while the oral steroid group showed 43% improvement and an odds ratio of 1.5 (95% CI 0.30–7.43, p-value 0.62). The steroid treatment group showed better visual acuity improvement than the no treatment group, and the intravenous steroid injection group showed 5.5 times greater improvement in visual acuity compared to the no treatment group.

PURPOSE: To report a case of posterior ischemic optic neuropathy accompanied by carotid artery plaque in a patient with retrobulbar optic neuritis. CASE SUMMARY: A 48-year-old man visited our clinic complaining of headache, decreasing visual acuity and defect of inferior visual field in his left eye for 3 days. The best corrected visual acuity was 1.0 in the right eye and 0.1 in the left eye. The anterior segment state, intraocular pressure, fundus examination and optical coherence tomography were normal in both eyes. Relative afferent pupillary defect, color vision deficiency and total scotoma were observed in his left eye. The results of the laboratory test and brain magnetic resonance imaging were normal. He was discharged from the hospital after 3 days of systemic steroid treatment on the basis of retrobulbar optic neuritis. A week later, fluorescent angiography and carotid ultrasonography were performed because of his history memory loss and left upper limb weakness before admission. A focal filling defect of the peripapillary area was found on fluorescent angiography. A plaque with a thickness of 1.9 mm and a length of 1.4 cm was found on carotid ultrasonography. After 6 months, the best corrected visual acuity was 0.4 in the left eye and the visual field showed a partially improved defect. CONCLUSIONS: Fluorescent angiography is recommended for potential posterior ischemic optic neuropathy in patients with retrobulbar optic neuritis, even though it is rare. Carotid ultrasonography is useful in finding atherosclerosis to prevent stroke or cardiovascular disease if ischemic cause is suspected on fluorescent angiography.

Factor XIII (fibrin stabilizing factor) has roles of stabilizing clot and cross-linking fibrin polymer, so the congenital factor XIII deficient patient has clot unstability and delayed bleeding episodes. We experienced a case of 11 years old girl who had experienced delayed umbilical healing, several episodes of intraabdominal and intracranial hemorrhage. But her coagulation screening studies with prothrombin time, aPTT (activated partial thromboplastin time), bleeding time showed normal value at each episode. These findings suggested typical features of congenital factor XIII deficiency. We used semiquantitative method to diagnose Factor XIII deficiency and quantify Factor XIII. We has treated her successfully with prophylactic fresh frozen plasma through plasmapheresis from two donors.

Background:
In this study, we aimed to investigate the recent trends for health care indicators including maternal mortality ratio, infant mortality rate, under-five mortality rate, life expectancy, years of life lost, and healthcare resources in South Korea, North Korea, Germany, Russian Federation, Mongolia, Vietnam, China, Czech Republic, Poland, and Hungary.
Methods:
We used data from five sources: World Health Organization, Federal Institute for Population Research, World Bank, Organization for Economic Cooperation and Development health statistics, and national statistics.
Results:
In the early 1990s, health indicators continued to improve in countries that switched to the health insurance system, but the gap widened in North Korea as health indicators worsened.
Conclusion
The establishment of a sustainable health care system after unification of the Korean peninsula requires substantial changes in the health care system and efforts to improve the health of North Koreans.

Forty cases of infiltrating duct carcinoma of the breast were examined immunohistochemically for expression of TGF-beta and angiogenesis in order to analyze significant correlation with prognostic parameters including tumor size, axillary lymph node metastasis, clinical stage, histologic grade, estrogen receptor and progesterone receptor status. The TGF-beta expression was observed in tumors center and advancing edges of tumors. To determine microvessel density for angiogenesis, we stained endothelial cells for Factor VIII related antigen and counted microvessel within tumor. The results were as follows: 1) The strong immunohistochemical expression of TGF-beta and higher counts of microvessels were observed in advancing edges of tumors (p<0.05). 2) The TGF-beta expression in the advancing edges of tumors was closely related to clinical stage and presence of axillary lymph node metastasis (p<0.05). 3) The mean microvessel counts were significantly higher in tumors from patients with axillary lymph node metastasis and increased with increasing clinical stage (p<0.05). 4) The TGF-beta expression was not related to histologic grade, estrogen receptor and progesterone receptor status(p>0.05). Therefore, the results suggested that the TGF-beta expression and angiogenesis in infiltrating duct carcinoma of the breast may play an important part in prognostic factors, closely related to the lymph node metastasis and clinical stage.
