STUDY OBJECT: To date, the study of critical illness in the emergency department has been limited. The purpose of this study was to determine the length of stay and procedures performed on critical care patient in ED, and to be help to establish Emergency physicians' education program. METHOD: We reviewed patient's medical record, who visited ED, Korea Univ. Hospital from Jan. 1996 to Jun. 1996 and admitted to ICU. We analyzed data to age, sex, clinical diagnosis, length of stay, and critical procedures in ED. RESULTS: The 12,721 patients visited ED during the study period, the 441 of 12,721 (3.50%) patients admitted to ICU. 56 patients were excluded whose medical re cords were incomplete. The study populations consisted of 165 women and 220 men. The mean age were 52 year old (median,58 year old). The mean length of stays were 606.1 (1445.9 minutes (median, 180 minutes)). One hundred sixty one of these patients (41.8 %) received one or more critical procedures. The medical critical patients were 252 cases, and surgical critical patients were 133 cases. The mean length of stay of medical critical patients was 738.8 (1748.9 minutes (median, 177.5 minutes)) in medical department,44.0% of them received critical procedures in ED. The surgical critical patients averaged 354.9 (410.7 minutes (median, 190 minutes)) and 37.6% received critical procedures. CONCLUSION: Critical ill patients stay in the ED with a substantial amount of time, before addition to the ICU. Critical ill patients who have hemodynamiccal unstable conditions, compromised cardiopulmonary functions, and neurologic deficities, were managed in ED frequently. Typical critical care procedures are commonly performed by emergency physicians. Therefore, it is important for emergency physician to prepare to critical ill patients.

PURPOSE: The prognosis of non-Hodgkins lymphoma (NHL) in elderly patients seems to be poorer than that in patients aged less than 60 years. This may be due to the lower tolerance for combination chemotherapy in the elderly. Aggressive combination chemo-therapy, which is the treatment of choice in intermediate and high grade NHL of adulthood, may be associated with unpredictab1y severe and lethal toxicity and worsened quality of life in the elderly. We investigated the treatment responses, toxicities and prognostic factors of NHL in elderly patients treated with combination chemotherapy. MATERIALS AND METHODS: We treated 116 elderly (>60 yrs) patients with NHL between January 1986 and June 1996 with adriamycin-containing regimens, such as CHOP (cyclo- phosphamide, adriamycin, vincristine, prednisolone), BACOP (bleomycin, adriamycin, cyclophosphamide, vincristine, prednisolone), and mBACOP (methotrexate, bleomycin, adriamycin, cyclophosphamide, vincristine, prednisolone). Patients in this study ranged from 60 to 81 (median 67) years of age. Fifty-five percent of patients were in stage I or II and the rest (45%) were in stage III or IV. The histologic grade was predominantly (91%) of intermediate and high grade type. RESULTS: The treatment responses were complete (CR) in 55% and partial (PR) in 25%. The median durstion of CR was 32 (3-132) months. The CR rate was significantly higher in patients treated with RDI (relative dose intensity) > 75% than that in the patients treated with RDI < 75% (p 0.003), but there was no significant difference in CR rate between treatment regimens (p-0.38). At a median follow up of 48-months (range, 12 to 132 months), the estimated 5-year ovetall survival was 46%. Ann Arbor Stage (I, II vs III, IV), ECOG performance (0-1 vs 2-3), RDI (>75% vs <75%) and the treatment response were important prognostic factors in the univariate analysis, and the treament response (CR vs non-CR) was the only independent prognostic parameter in the multivariate analysis. The most frequent and severe toxicity associated with chemotherapy was infection with or without neutropenia. The rate of severe infection was significantly decreased in the patients supported with G/GM-CSF but not in the dose-reduction group (RDI<75% vs >75%). CONCLUSION: Our data suggests that achievement of the CR after combination chemotherpy is the most important prognostic factor in the elderly patients with NHL. Suboptimal chemotherapy (RDI<75%) reduced the complete remission rate without reducing the likelihood of developing severe toxicities. Optimal chemotherapy with supportive cares involving the use of hematopoietic growth factors may be needed to improve the treatment response and the survival in the elderly patients with aggressive NHL.

PURPOSE: Conventional intravenous nutrition has been given as a solution of amino acids combined with dextrose and a separate line delivering a lipid emulsion. This technique was unsatisfactory, however, because of difficulties in managing technical and metabolic complications. Since the first clinical use of a single solution containing all the necessary nutrients was introduced in 1976, the total nutrient admixture (TNA) system has been used. However, despite the numerous advantages of this TNA system, it has not been used worldwide because of an assumption about unstability of this admixture. This study was conducted to compare the physical stability of TNA systems using two different 2 commercially available amino acid solutions and fat emulsions. METHODS: Each group contained 600 ml of 20% dextrose, 250 ml of 10% amino acid solution, 250 ml of 10% fat emulsion, 0.2 ml of heparin, and 20 ml of electrolyte solution was investigated for 7 days while being stored 4oC and at ambient temperature. The stabilities of these admixtures were compared by noting changes in macroscopic appearance, pH, osmolarity, Zeta-potential, peroxide value, particle size and distribution, and fat composition. RESULTS: When an amino acid solution containing P 2 was used, a supernatant yellow band was observed from the 3rd day at ambient temperature. The pH and peroxide value also showed significant changes, but these changes did not exceed the product-specifications. When an amino acid solution without P 2 was used, no significant change was observed. CONCLUSION: TNA systems are physically stable at 4oC temperature for at least 7 days, but TNA systems prepared with amino acid solution containing P 2 are not stable at ambient temperature from the 3rd day. On the other hand, TNA systems prepared with an amino acid solution without P 2 are stable at ambient temperature for 7 days. Various commercially available fat emulsions containing 10% soybean oil did not affect the stability of TNA systems.

7.A Potential Role of Crystallin in the Vitreous Bodies of Rats after Ischemia-reperfusion Injury.
Korean Journal of Ophthalmology 2012;26(4):248-254
PURPOSE: Ischemia-reperfusion injury (I/R injury) is known not only to induce hypoxic and oxidative stress, but also to cause retinal degeneration in rats. Crystallins, known to inhibit the formation of reactive oxygen species, reduce apoptotic cell death. Our goal was to clarify not only the role of I/R injury-mediated crystallins, but also to evaluate the correlation of these compounds to anti-inflammation in the vitreous body. METHODS: Twenty-four Sprague-Dawley rats were used in this study. We induced I/R injury by clamping the optic nerve for 30 minutes and then releasing it. The vitreous bodies were obtained from the experimental and control subjects 24, 48, and 72 hours after I/R injury. Two-dimensional electrophoresis was performed, and the targeted spots were further investigated using matrix-assisted laser desorption-ionization time-of-flight mass spectrometry, spectrophotometry, Western blotting, and histological examination. RESULTS: After I/R injury, 23 spots were identified as crystallins. The betaB2 crystallins were transcriptionally and post-translationally regulated, whereas the alphaB crystallins were controlled by post-translational modifications in the vitreous bodies of the rats. The total amounts of alphaA and beta crystallins (including isotypes of beta crystalline) had increased 48 hours after injury. The phosphorylation of alphaB crystallin (at serine residues 19, 45, and 59) was significantly increased 48 hours later, whereas phosphorylation of ERK1/2 showed the greatest decrease. CONCLUSIONS: During hypoxic and oxidation stress, our results suggest that phosphorylated alphaB crystalline inhibits RAS, resulting in the inactivation of ERK1/2. The phosphorylation of alphaB crystallin may be associated with the inflammatory suppression in the vitreous body via the I/R injury model system.

BACKGROUND: Domestic violence once considered an infrequently occurring event existing only in deviant relationships, it has been more recently recognized as a widely distributed phenomenon resulting from multiple cultural, social, psycological factors. According to declining world economics, family violence rises with a simultaneous curtailment of agencies available to assist battered persons and there is increasing pressure on emergency departments to serve those who might otherwise have sought help from public agency. In Korea, we don't have any clinical data about domestic violence, and authors analysed clinical pictures of domestic violence victims who came to the emergency department of Korean University medical center. METHOD: We reviewed the victims of the domestic violence retrospectively, who visited in ED, Korean Univ. Hospital from Jan. 1996 to the Dec. 1996. We Analysed data to Age, sex, Injury severity score, location of injury, mechanism, perpetrator. RESULTS: During the study period, total 134 domestic violence victims were identified. The young, females were predominantly victimized. And married women were more commonly violated. (about 70%). ISS was relatively mild (2.491), face and head were mainly injured by punching and objects throwing. The Prevalence of domestic violence victims almost presented at Emergency department between 6:00/P.M. and 8:00 A.M.. CONCLUSION: Emergency physicians suspect domestic violence victims who injured at face and head by punching or hitted would. In these patients, we need more detail history and physical exam. And in case of repeated domestic violence, refer to neuropychatry dept and social workers with perpetratrs, and need mere concerte social programs for domestic violence.

10.A Case of Optic Neuritis Complicating Herpes Zoster Ophthalmicus in a Child.
Korean Journal of Ophthalmology 2010;24(2):126-130
Here we report a case of optic neuritis in the setting of herpes zoster ophthalmicus (HZO) in a child. A six-year-old girl presented with HZO in the right eye. During the hospitalization, her visual acuity decreased. Fluorescein angiography (FAG) and optical coherence tomography revealed optic neuritis in the affected eye. Visual acuity improved with one month of treatment with acyclovir and steroids. FAG analysis showed no evidence of leakage at the optic disc. At one year post treatment, the patient's fundus exam and vision were normal. Therapy with antivirals and steroids may be effective in patients with childhood HZO optic neuritis
