BACKGROUND: Dopamine is an inotropic agent that is often selected for continuous infusion. For hemodynamic stability, the rate of infusion is controlled in the range of 5-15 µg/kg/min. This study aimed to compare the time intervals from the administration of dopamine to the onset of its hemodynamic effects when dopamine was administered through three different peripheral veins (the cephalic vein [CV], the great saphenous vein [GSV], and the external jugular vein [EJV]). METHODS: Patients in group 1, group 2, and group 3 received dopamine infusions in the CV, GSV, and EJV, respectively. A noninvasive continuous cardiac output monitor (NICCOMO™, Medis, Ilmenau, Germany) was used to assess cardiac output (CO) and systemic vascular resistance (SVR). Six minutes after intubation, baseline heart rate (HR), systolic blood pressure (BP), diastolic BP, mean arterial pressure (MAP), CO, and SVR values were recorded and dopamine infusion was initiated at a dose of 10 µg/kg/min. Hemodynamic changes at 0, 4, 8, 12, and 15 minutes postinfusion were recorded. RESULTS: No statistically significant differences were observed among the three groups with respect to the rate of hemodynamic change. In all groups, systolic BP, diastolic BP, MAP, and SVR tended to increase after decreasing for the first 4 minutes; in contrast, HR and CO decreased until 8 minutes, after which they tended to reach a plateau. CONCLUSIONS: For patients under general anesthesia receiving dopamine at 10 µg/kg/min, there were no clinical differences in the effect of dopamine administered through three different peripheral veins.

BACKGROUND: The purpose of this study was to investigate AIDS-specific knowledge, attitudes, and behaviors of auxiliary police on duty in Seoul and to provide basic data for use in AIDS prevention education for auxiliary police. METHODS: In November 2008, we questioned 402 auxiliary police in the Mobile Police Force located in Seoul by using a self-administered questionnaire containing 39 items. RESULTS: Of the respondents, 98.5% were unmarried and scored, on average, 2.95+/-0.98 out of 4 with respect to their knowledge about the transmission routes of HIV infection. Approximately 70.6% of the respondents were sexually active in the past year and 6.3% were diagnosed with or treated for a venereal disease within the past year. Approximately 42.5% of the respondents had sex with someone other than their steady partner and 35.5% of these respondents did not use condom during sexual intercourse. Approximately 77% of the respondents were willing to be anonymously tested for HIV infection that may have been acquired because of unprotected sexual activity during the past year (P=0.018). CONCLUSION: Providing assertive education, as well as additional support and instructions, is necessary to raise awareness about the prevention of AIDS among auxiliary police.

A purpose of present study is to provide basic information evaluating the utility of Magnetic Resonance imaging as a biological marker estimating manganese effects to central nervous system among welders, which is conducted by comparing urinary and blood manganese concentrations and signal intensities of brain MR images between exposed group and non-exposed group, evaluating the objectivity of subjective grading estimated by correlations between Pallidal signal intensity index (P. I) and subjective grades among exposed group, and comparing the difference of signal intensities according to presence of neurologic symptoms, signs and exposure variables among the exposed group. The exposed group is composed of 11 welders complaining severe symptoms or showing neurological signs, and the non-exposed group is composed of 5 patients who admitted a hospital. Urinary manganese concentrations and signal intensities in T1-weighted MR images among exposed group were higher than those of the non-exposed group significantly, which exhibits that increased signal intensities in T1-weighted MR image represent the effect of manganese exposure. P. Is among the exposed group revealed relatively high correlations with subjective grades ( gamma =0.63, p=0.037) , which suggests the objectivity of subjective grade. Signal intensity in globus pallidus was a suitable single variable representing the effect of manganese accumulation in C.N.S system appropriately, which was verified as follows ; Increased signal intensities among the exposed group had the highest frequency and intensity in the globus pallidus, and the P.I. had a relatively high correlation coefficient ( gamma 0.62, p=0.044) with total score of subjective grades. Signal intensity with subjective grading in globus pallidus represented very high correlation gamma =0.97, p=0.00) with total score of subjective grades, and had a similar correlation coefficient with many variables. It is hard to argue that signal intensities are markers representing pathologic change in C.N.S system or can be used as a diagnostic tool for manganese intoxication, because signal intensities had no difference between the exposed group and the non-exposed group according to presence of neurological signs.

PURPOSE: This study was conducted to analyze and clarify the meaning of the concept for relocation stress -focusing on patients transferred from an intensive care unit to a general ward. METHODS: This study used Walker and Avant's process of concept analysis. RESULTS: Relocation stress can be defined by these attributes as follows: 1) involuntary decision about relocation, 2) moving from a familiar and safe environment to an unfamiliar one, 3) broken relationship of safety and familiarity, 4) physiological and psychosocial change after relocation. The antecedents of relocation stress consisted of these facts: 1) preparation degrees of transfer from the intensive care unit to a general ward, 2) pertinence of the information related to the transfer process, 3) change of major caregivers, 4) change in numbers of monitoring devices, 5) change in the level of self-care. There are consequences occurring as a result of relocation stress: 1) decrease in patients' quality of life, 2) decrease in coping capacity, 3) loss of control. CONCLUSION: Relocation stress is a core concept in intensive nursing care. Using this concept will contribute to continuity of intensive nursing care.

PURPOSE: To report 2 cases of skin necrosis over the medial canthus following canaliculodacryocystorhinostomy in young women diagnosed with canalicular obstruction. CASE SUMMARY: (Case 1) A 31-year-old female presented to our clinic with epiphora in the right eye that had developed 2 years prior. On examination, a right upper and lower canalicular obstruction was noted and the patient underwent canaliculodacryocystorhinostomy with silicone tube intubation. Topical 0.04% mitomycin-C eyedrops were applied twice a day from postoperative day 1 for 7 days. The patient revisited our emergency center with swelling, redness, and tenderness in the medial canthal region that developed 3 days after the initial surgery. Furthermore, a skin ulceration had developed followed by an exudative oozing with crust. (Case 2) A 23-years-old female visited our clinic with epiphora in the right eye that had developed 3 months prior. Ophthalmic examinations revealed a common canalicular obstruction in the right eye and canaliculodacryocystorhinostomy with silicone tube intubation was performed. Seven days postoperatively, the patient developed mild pain and tenderness over the right lacrimal sac and medial canthal erythema with purulent discharge was noted. Furthermore, a localized skin necrosis had developed. CONCLUSIONS: Localized skin necrosis may rarely develop after canaliculodacryocystorhinostomy in young women. If localized skin symptoms develop postoperatively, the patient should be closely monitored.

PURPOSE: This study investigated various factors relatied to wandering behavior of Korean elders with dementia (KED). METHODS: A sample of 160 ambulatory residents with dementia from 14 long term care facilities was used to examine demographic, individual, cognitive, physical health, and environmental characteristics by comparing wanderers (N=108) to nonwanders (N=52). Subjects were evaluated by Korean versions of the Mini-mental State Exam (K-MMSE), the Physical and Instrumental Activities of Daily Living (K-PIADL), and the Revised Algase Wandering Scale Nursing Home version (KRAWS-NH) along its six dimensions. Demographic and environmental data were also obtained. Independent sample ttests, Chi-square test, Fisher's Exact tests, and ANCOVAs were used to examine differences between wanderers and nonwanders. RESULTS: Wanderers were significantly (p<.05) older and had more limitations in K-PADL and K-IADL. The degree of overall wandering and certain features of wandering were significantly different (p<.05) by total number of residents in the facility, type of bedroom (i.e., "Ondol"), and color of bedroom and living-room walls (i.e., sky blue). CONCLUSIONS: Findings of this study may be useful in understanding wandering behavior of KEDs and thus developing more culturally specific management strategies.

BACKGROUND: To access the accuracy and clinical usefulness of microplate identification (ID) system for the identification of Enterobacteriaceae, we compared microplate ID system with API 20E(bioMerieux, Etoile, France). METHODS: Ninety-two cultures of Enterobacteriaceae and one isolate of Aeromonas species were simultaneously identified by microplate ID system and the API 20E. Twenty biochemical tests used in microplate ID system were lactose, sucrose, and H2S in Kligler's iron agar media; indole, sucrose, raffinose, arabinose, trehalose, adonitol, dulcitol, sorbitol, cellibiose, methy-red, phenylalanine deaminase, ornithine decarboxylase, lysine decarboxylase, arginine dihydrolase, urease, and citrate in microplate; and oxidase test. The identification was obtained by considering percent likelihood(% ID), modal frequency and ID score method. RESULTS: Among the 92 cultures of Enterobacteriaceae and one isolate of Aeromonas species, agreement rate of identification according to the % ID between microplate ID system and API 20E were 90.3% to the species level and 97.8% to the genus level. CONCLUSIONS: For the identification of clinical Enterobacteriaceae isolates, the microplate ID system compares favorably with API 20E in identification accuracy and have the advantage of costsaving and easy to use.
