Postoperative endophthalmitis following cataract surgery is rare but may influence the final visual outcome markedly. The authors reviewed the clinical records of 16 patients who had been treated with the diagnosis of endophthalmitis after cataract surgeries from March. 1992. to September, 1995. We analysised their final visual outcomes according to cultured microorganisms, durations of symptom onset after the surgeries, the methods of antibiotic administration and treatment methods with or without vitrectomies. Final visual accuities were 0.5 or better in 50% of all eyes, 0.15 or better in 75% and light perception or worse in 4 eyes(25%). Twelve(75%) of all eyes were cultured in positive. Five of twelve culture proven cases were Staphylococcus epidermidis and five were Pseudomonas aeruginosa. Each case of Xanthomonas maltophilia and fluorescens were cultured. All 5 cases infected by gram positive organisms had got visual accuity of 0.15 or better but 4 of 7 eyes infected by gram negative ones had got. We treated 9 patients with intravitreal, subconjunctival and systemic antibiotics but did 7 without systemic antibiotics. Six cases(85.7%) of these had got visual accuity of 0.15 or better but 6 cases(66.7%) of those had got. One of five patients who had undergone therapeutic vitrectomies had got visual outcome of 0.15 or better but all eleven without vitrectomy had got.

A study on objective personality characteristics of 41 central serous chorioretinopathy patients was performed to investigate the etiologic relationship of psychological behaviors about the central serous chorioretinopathy. Fourty-one healthy subjects were used as a control group. Authors used the Minnesota Multiphasic Personality Inventory (MMPI) which consisted of 4 validity scales and 10 clinical scales. Three neurotic scales of hypochondriasis, depression and hysteria in the atients group were significantly higher than in the normal control group even though the mean scores on each clinical scale were within normal ranges in both groups.

Hemangiopericytoma is an uncommon mesenchymal tumor that may be benign or malignant. This tumor is composed of proliferating capillaries and spindle-shaped cells known as the pericytes of Zimmermann. Since all capillaries have pericytes, hemangiopericytoma can be found anywhere In the body. We report a case of malignant hemangiopericytoma in the pelvic cavity which was treated by radical excision and adjutant radiotherapy and discuss the clinicopathological feature, prognosis, and therapy of this lesson.

Purpose: This study aimed to conduct a scoping review of studies on interventions for the prevention of safety accidents involving infants. Methods: The scoping review method by Arksey and O'Malley was used to conduct an overview based on information spanning a wide range of fields. Multiple electronic databases, PubMed, CINAHL, RISS, and KISS, were searched for articles written in English or Korean published from 2012 to the present on safety accident prevention interventions. A total of 2,137 papers were found, and 20 papers were ultimately analyzed. Results: Most studies were conducted in the United States (55.0%) and in the medical field (45.0%), and most were experimental studies (35.0%). The results were organized across five categories: 1) preventive precautions, 2) characteristics of children's developmental stages, 3) encouraging voluntary participation, 4) continuity of interventions, and 5) teaching methods. Conclusion Safety accident prevention interventions should cover the establishment of a safe home environment, include voluntary participation, and provide routine follow-up interventions. Additionally, practical training and teaching methods that incorporate feedback rather than a lectureoriented approach should be adopted.

A 27-year-old man with bacterial endocarditis of the mitral valve and embolic episodes was bound to have a large right coronary artery fistula communicating with the left ventricle, immediately inferior to the posterior mitral annulus. The perforation of the posterior leaflet and coronary arteriovenous fistula was identified using two-dimensional Doppler echocardiography. The diagnosis was confirmed by coronary angiography, and the patient underwent a successful operation.

PURPOSE: This study was carrid out to assess the feasibility of cancer registry program (KCR) in Kwangju metropolitan city, Korea. MATERIALS AND METHODS: The incidence cases and mortality data were mainly collected from the Korean national cancer registry system (NCR) and other resources such as medical insurance records, hospital records, pathology reports, radiation records and death certificates of 1996 in Kwangju metropolitan city. RESULTS: This study identified 1,422 cases of cancer in 1996, which was about 1379o more than NCR. Cancer cases reported from the hospitals outside Kwangju metropolitan city reached almost 40% of total cases. Death certificate notification percent (DCN%) in 1996 was estimated about 31.1%. The proposed KCR would cover more than 95% of cancer cases in Kwangju metropolitan city. CONCLUSION: The proposed KCR seems feasible in collecting cancer date with reasonable accuracy.

Recently, a method of color Doppler sonography has been described that is based onestimation the integrated Doppler power spectrum which is represented as "Power Doppler"ultrasonography. Several potential advantages of Power Doppler ultasonography overconventional color Doppler ultrasonography include that noise is represented in uniform patternin power mode, the relative angle independence and abscence of aliasing effect. It appearsto be a potentially useful particularly for evaluating slow flow in parts of the body wherethe signal is weak because blood vessels are small or deep. This could be applied to theevaluation of the flow in the ovarian tumors. And it is believed that the analysis of bloodflow characteristics as well as angiogenesis location and the amount and arrangement ofmicrovascular network may help in distinguishing malignant versus benign tumors.We will represent a preliminary report to demonstrate a efficacy of power Dopplerultrasonography in the detection of ovarian tumor vascularity. Thirty-one patients with ovarianmasses were prospectively evaluated with power and conventional color Dopplersonography using 7.0 MHz endovaginal probe or 3.0 MHz transabdominal probe with a pulserepetition frequency of 700 Hz. The evaluation criteria were the detection of vasculature,the arterial waveform analysis if possible, and defining the vascular location. With conventionalcolor Doppler sonography, the vascularity within the ovarian tumors could be detectedin 74.2% of total patients, and 90.3% of total patients with power Doppler sonography,Doppler waveform analysis was possible in 83.9% of total patients with power Dopplersonography and in 71.0% at conventional color Doppler sonography. The vascular patternswithin each parts(solid area, septum, pericystic) of the ovarian tumors were relatively welldefined with power Doppler sonography as compare to those with conventional color Dopplersonography.In conclusion, power Doppler ultrasonography was shown to be superior to conventionalcolor Doppler ultrasonography in the depiction of ovarian intratumoral vasculature.

In other to study relationship of anxiety and serum cholesterol in general population, we performed the interview survey and screening test for the Ju-am cohort and residents in controlling area at 1995. Among them, 622 people are selected for this analysis. The results were summarized as follows. 1. Anxiety and total serum cholesterol related each other in the group of anxiety. Correlation coefficient was 0.39(p<0.01). 2. According to the result of multiple regression that the total serum cholesterol regarded as the dependent variable, anxiety and total serum cholesterol were related each other positively in the group of anxiety(p<0.05). 3. As the symptoms of anxiety was dichotomized affective and somatic symptom. There was no relationship of 2 symptoms and total serum cholesterol in all subjects, but there was more relationship on the affective symptom than on the somatic symptom in the group of anxiety(p<0.05). The above results show that anxiety and total serum cholesterol related each other significantly in the anxiety group. And the relationship of psychological factors and serum cholesterol could be applied significantly in general population as well as in the special group.

Poria cocos is a well-known traditional Chinese traditional medicine (TCM) that grows around roots of pine trees in China, Korea, Japan, and North America. Poria cocos has been used in Asian countries to treat insomnia as either a single herb or part of an herbal formula. In a previous experiment, pachymic acid (PA), an active constituent of Poria cocos ethanol extract (PCE), increased pentobarbital-induced sleeping behaviors. The aim of this experiment was to evaluate whether or not PCE and PA modulate sleep architectures in rats as well as whether or not their effects are mediated through GABA(A)-ergic transmission. PCE and PA were orally administered to individual rats 7 days after surgical implantation of a transmitter, and sleep architectures were recorded by Telemetric Cortical encephalogram (EEG) upon oral administration of test drugs. PCE and PA increased total sleep time and non-rapid eye movement (NREM) sleep as well as reduced numbers of sleep/wake cycles recorded by EEG. Furthermore, PCE increased intracellular chloride levels, GAD65/67 protein levels, and alpha-, beta-, and gamma-subunits of GABA(A) receptors in primary cultured hypothalamic neuronal cells. These data suggest that PCE modulates sleep architectures via activation of GABA(A)-ergic systems. Further, as PA is an active component of PCE, they may have the same pharmacological effects.

The purpose of this study was to examine the mortality risk associated with cognitive impairment among the rural elderly. The subjective of study was 558 of 'A Study on the Depression and Cognitive Impairment in the Rural Elderly' of Jung Ae Rhee and Hyang Gyun Jung's study(1993). Cognitive impairment and other social and health factors were assessed in 558 elderly rural community residents. For this study, a Korean version of the Mini-Mental State Examination(MMSEK) was used as a global indicator of cognitive functioning. And mortality risk factors for each cognitive impairment subgroup were identified by univariate and multivariate Cox regression analysis. At baseline 22.6% of the sample were mildly impaired and 14.2% were severely impaired. As the age increased, the cognitive function was more impaired. Sexual difference was existed in the cognitive function level. Also the variables such as smoking habits, physical disorders had the significant relationship with cognitive function impairment. Across a 3-year observation period the mortality rate was 8.5% for the cognitively unimpaired, 11.1% for the mildly impaired, and 16.5% for the severly impaired respondents. And the survival probability was .92 for the cognitively unimpaired, .90 for the mildly impaired, and .86 for the severly impaired respondents. Compared to survival curve for the cognitively unimpaired group, each survival curve for the mildly and the severely impaired group was not significantly different. When adjustments models were not made for the effects of other health and social covariates, each hazard ratio of death of mildly and severely impaired persons was not significantly different as compared with the cognitively unimpaired. But, as MMSEK score increased, significantly hazard ratio of death decreased. Employing Cox univariate proportional hazards model, statistically other significant variables were age, monthly income, smoking habits, physical disorders. Also when adjustments were made for the effects of other health and social covariates, there was no difference in hazard ratio of death between those with severe or mild impairment and unimpaired persons. And as MMSEK score increased, significantly hazard ratio of death did not decrease. Employing Cox multivariate proportional hazards model, statistically other significant variables were age, monthly income, physical disorders. Employing Cox multivariate proportional hazards model by sex, at men and women statistically significant variable was only age. For both men and women, also cognitive impairment was not a significant risk factor. Other investigators have found that cognitive impairment is a significant predictor of mortality. But we didn't find that it is a significant predictor of mortality. Even though the conclusions of our study were not related to cognitive impairment and mortality, early detection of impaired cognition and attention to associated health problems could improve the quality of life of these older adults and perhaps extend their survival.
