It is recognized that rebleeding of traumatic hyphema may predispose patients to several complications including decreased visual acuity. We reviewed the medical records of 92 patients(92 eyes) with the diagnosis of nonperforating traumatic hyphema. The relative efficiencies of Aminocaproic acid and systemic Predisolone for reducing rate of rebleeding and their side effects were evaluated under the statistical analysis. Fourty-seven patients received an oral dosage of 50 mg/kg of Aminocaproic acid every 4 hours for 5 days(up to a maximum 30 gm/day), and fourty-five patients took an oral dosage of 0.6 mg/kg of Prednisolone daily in two devided doses. The frequency of rebleeding was not statistically significantly different between the aminocaproic acid treated group(4.3%, 2/47 patients) and the prednisolone treated group(6.7%, 3/45 patients). The developing rates of their acute adverse reaction were statistically different between the aminocaproic acid treated group(44.7%, 21/47 patients) and the prednisolone treated group(20%, 9/45 patients).

PURPOSE: To investigate the incidence of breast arterial calcification in Korean women, and to determine its association with systemic diseases and carotid arterial atherosclerosis. MATERIALS AND METHODS: One thousand seven hundred and thirteen female subjects who underwent mammography at a health care center between May 1999 and May 2000 were included in this study. Of the total, 172 were found to have breast arterial calcification, and were classified according to age. The coincidence of hypertension, diabetes mellitus and hyperlipidemia was examined in both the subject group and the control group selected on the same age basis. To investigate the presence and degree of carotid atherosclerosis, sonographic maging was performed and the findings were compared between the two groups. RESULTS: The incidence of breast arterial calcification showed statistically significant differences according to age, with a higher incidence in older patients (p<0.05). However, there was no statistical difference in the incidence of hypertension, hyperlipidemia, and diabetes mellitus between groups. Carotid atherosclerosis was subjects more prevalent among subjects than in the control group (p<0.05), though there was no statistically significant difference in the degree of luminal stenosis. CONCLUSION: The most common pathologic cause of breast arterial calcification is arteriosclerosis. Breast arterial calcification is demonstrated at mammography, along with other clinical risk factors for atherosclerosis or coincidental neurologic symptoms. We stress that further evaluation of the carotid artery is necessary.

Argon laser trabeculoplasty(ALT) is commonly used in the treatment of uncontrolled open angle glaucoma. The authors retrospectively reviewed the efficacy of ALT in 52 patients(57 eyes) with primary open angle glaucoma. The mean follow-up was 28 months(range 2-48 months). The decrease in intraocular pressure 10P) was 10.1 +/- 3.5 mmHg at 1 month, 8.2 +/- 2.8 mmHg at 1 year, 6.2 +/- 5.1 mmHg at 2 years and 51% at 3 years. Failure was most common in the first 6 months after treatment(29%) and thereafter failure occurred at a rate of 5% to 15% per year. The sex and age of patients had no significant effect on success rate. The success rate was high in the patients with baseline IOP of 26 to 30 mmHg. A mild iritis in all cases, transient rise in IOP, peripheral anterior synechia and microscopic hyphema were noted as early complications of ALT.

BACKGROUND: Beta-adrenergic receptor Kinase 1(betaARK1) is a serine/threonine kinase attached, which inhibits the coupling of beta-adrenergic receptor with G-protein. Myocardial betaARK1 level is usually elevated in heart failure and hypertrophy, but it is not known whether the circulating betaARK1 level is related with the degree of cardiac hypertrophy. This study was performed to evaluate the association of the betaARK1 level in circulating mononuclear leukocytes(MNL) in untreated hypertension with left ventricular mass in hypertensive patients. Method: Nineteen non-treated hypertensive patients were included for this study. High blood pressure was confirmed when systolic BP is over 150 mmHg or diastoli BP is over 95 mmHg. Echocardiography was performed to evaluate the degree of hypertrophy by measuring the left ventricular mass index(LVMI) and relative wall thickness(RWT), and test the LV function by measuring the ejection fraction(EF) according to ASE guideline. At the same time, blood was collected from each patient and MNL were isolated by gradient centrifuge with Ficoll-400. Total RNA was purified from MNL and semi-quantitative RT-PCR was performed. After reverse transcription, PCR was done with primers for human betaARK1 and GAPDH as external control. betaARK1 levels were expressed by ratio to GAPDH level and estimated the relations with clinical and Echocardiographic parameters. Result: We studied confirmed 19 hypertensive patients(10 men and 9 women, mean age of 50.6 years). Echocardiographically measured indices(mean+/-SD) were as follows; LVMI(137.3+/-30.6g/m2), PWT(0.53+/-0.09) and EF(54.6+/-8.5%). Ratio of betaARK1 levels to GAPDH was from 0.10 to 0.96 (0.62+/-0.25). betaARK1 levels were correlated with LVMI(correlation coefficient: r=.502, p=.029) and RWT(r=.627, p=.004). But Systolic BP(r=0.009, p=.93), diastolic BP(r=.07, p=.85) or EF(r=.045, p=.84) were not related to level of betaARK1. CONCLUSIONS: The betaARK1 level of circulating MNL was correlated well with the degree of the cardiac hypertrophy estimated by LVMI and RWT. This data suggests that activation of sympatho-adrenal system would exert a major role in developing cardiac hypertrophy and we can expect the decreased responsiveness to catecholamine in the heart of hypertensive patients. betaARK1 in circulating MNL might be used as a predictor or marker for LV hypertrophy in hypertensive patients.

PURPOSE: The purpose of this study was to identify the reactions of emergency department nurses to violence. METHODS: Q-methodology which provides a method of analyzing the subjectivity of each item was used. Thirty emergency department nurses classified 33 selected Q-statements into a normal distribution using a 9 point scale. The collected data was analyzed using the Quanl PC Program. RESULTS: Three types of reactions to violence were identified. The first type(emotional and physical reactions) showed a sense of regret on the selection of an occupation and emotional and physical reactions such as anxiety, fear, depression, hopelessness, heart palpitations and trembling hands due to the violence. The second type(problem solving) actively coped to prevent the occurrence of violence, grasped the causes of violence and sought out a problem solving plan. The third type(anger reactions) felt a lot of anger against violence, and resented their reality of working under conditions of inadequately secured facilities and systems. CONCLUSION: The emotional and physical reactions type and the anger reactions type should be required to attend educational programs to improve attitudes and abilities to solve the problems in a more active and positive manner.

Pheochromocytoma is a rare endocrine tumor arising from the chromaffin tissue, and it is able to produce and secrete catecholamines. Lymph nodes, liver, lung and bone are the most frequent sites of metastasis. We report here on a case of pheochromocytoma arising from the dura in a patient who was surgically treated for bilateral pheochromocytoma five years previously.

To evaluate the effect of Morphine during spinal anesthesia with alpha-adrenergic agonist, we used 0.18 mg of epinephrine, 90 ug of clonidine and 0.3 mg of morphine with 12 mg of T-cain respectively and compared hemodynamic and analgesic effects of each drug. Eighty patients were divided into four groups as follows; Group I (n=20); T-cain with clonidine, Group II (n=20); T-cain with epinephrine, Group III (n=20); T-cain with clonidine and morphine, and Group IV (n=20); T-cain with epinephrine and morphine. The results were as follows; 1) The onset time of analgesia and the time reached to the highest level of sensory loss were most rapid in the epinephrine and morphine group. 2) The duration of analgesia was significantly prolonged in the group of epinephrine and morphine than the group of epinephrine and clonidine. 3) It was more likely complicated in the morphine groups than others but there was no significance. 4) Although the heart rate was gradually decreased over 60 min. after anesthesia, there was no significance between the groups. 5) Systolic and diastolic blood pressure were decreased mainly over 30~45 min. after anesthesia, but there was no significance. In conclusion, epinephrine can be sustituted for clonidine because analgesic duration was not significantly changed, and the duration of analgesia was prolonged by morphine.

Autogenous periosteal grafts are an attractive alternative to existing barrier membrane materials since they meet the reqiurements of an ideal material. But no histological data are available on the effectiveness of periosteal membranes in the treatment of periodontal defects. The purpose of this study was to evaluate effect of autogenous periosteal graft on periodontal regeneration histologically. Class II furcation defects were surgically created on the second, third and the fourth premolars bilaterally in the mandibules of six mongrel dogs. The experimental sites were divided into three groups according to the treatment modalities; control group - surgical debridement only; Group I- autogenous periosteal membrane placement after surgical debridement; Group II- autogenous periosteal membrane placement after surgical debridement and bone grafting. The animals were sacrificed at 2, 4 and 12 weeks after periodontal surgery and the decalcified and undecalcified specimens were prepared for histological and histometrical analysis. Clinically all treated groups healed without significant problems. Under light microscope, at 2 weeks, control group showed significant apical epithelial migration and bone remodelling only below the notch area. But for the group I, II with autogenous periosteal graft, less apical migration of epithelium appeared and large amount of osteoid tissue showed above the notch area. Grafted periosteal membrane was indiscernable at 4 weeks, so periosteal membrane might be organized to surrounding tissues. Histometrically, at 4 and 12 weeks, all the test and control groups didn't show significant change of epithelial zone but new attachment level tended to be gained in the test groups than control group. These results suggest that autogenous periosteal grafts should be a good alternative for guided tissue regeneration.

To evaluate the refractive error and glasses wering state, we performed screening eye examination on elementary school children living in rural area. Among 1254 shcool children(male : 542, female : 712), 352(28.1%) children were emmetropia and 902(71.9%) children ametropia. Three hundred ninety two(72.3%) of 542 male students and 510(71.6%) of 712 female students were not emmetropia. There was no statistical significance in sexual difference of refractive errors. As refractive errors, 38.3%(481) were myopia, 27.8%(348) hyperopia, and 5.8%(73( mixed astigmatism respectively. In diopteric distribution of refractive errors, refractive error under +/-2.0D was 72.0%(650/902). Among children with refractive errors, 333(36.9%) children did not require glasses, but rest of childfen needed glasses. Three hundred nine(34.3%) children did not wear glasses inspite of refractive errors, 33(3.7%) children were wearing incorrect glasses and 2 children were wearing glasses unnecessarily. In children, early eye examination is essential for their eye health. Therefore attention to early eye examination and correct glasses wearing seem to be very important especially for child living in rural area.
