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.

OBJECTIVE: The effects of cryopreservation with or without coculture on the in vitro development of blastomere-biopsied 8-cell mouse embryos were investigated. This experimental study was originally designed for the setup of a preclinical mouse model for the preimplantation genetic diagnosis (PGD) in human. METHODS: Eight-cell embryos were obtained after in vitro fertilization (IVF) from F1 hybrid mice (C57BLfemale symbol/CBAmale symbol). Using micromanipulation, one to four blastomeres were aspirated through a hole made in the zona pellucida by zona drilling (ZD) with acid Tyrode's solution (ATS). A slow-freezing and rapid-thawing protocol with 1.5M dimethyl sulfoxide (DMSO) and 0.1M sucrose as cryoprotectant was used for the cryopreservation of blastomere- biopsied 8-cell mouse embryos. After thawing, embryos were cultured for 110 hours in Ham's F-10 supplemented with 0.4% bovine serum albumin (BSA). In the coculture group, embryos were cultured for 110 hours on the monolayer of Vero cells in the same medium. The blastocyst formation was recorded, and the embryos developed beyond blastocyst stage were stained with 10% Giemsa to count the total number of nuclei in each embryo. RESULTS: The survival rate of embryos after cryopreservation was significantly lower in the blastomere-biopsied (7/8, 6/8, 5/8, and 4/8 embryos) groups than in the non-biopsied, zona intact (ZI) group. Without the coculture, the blastocyst formation rate of embryos after cryopreservation was not significantly different among ZI, the zona drilling only (ZD), and the balstomere-biopsied groups, but it was significantly lower than in the non-cryopreserved control group. The mean number of cells in embryos beyond blastocyst stage was significantly higher in the control group (50.2+/-14.0,) than in 6/8(26.5+/-6.2), 5/8(25.0+/-5.5), and 4/8(17.8+/-7.8) groups. With the coculture using Vero cells, the blastocyst formation rate of embryos after cryopreservation was significantly lower in 5/8 and 4/8 groups, compared with the control, 7/8, and 6/8 groups. The mean number of cells in embryos beyond blastocyst stage was also significantly lower in 4/8 group (25.9+/-10.2), compared with the control (50.2+/-14.0), 7/8 (56.0+/-22.2), and 6/8 (55.3 +/-25.5) groups. CONCLUSION: After cryopreservation, blastomere-biopsied mouse embryos have a significantly impaired developmental competence in vitro, but this detrimental effect might be prevented by the coculture with Vero cells in 8-cell mouse embryos biopsied one or two blastomeres. Biopsy of mouse embryos after ZD with ATS is a safe and highly efficient preclinical model for PGD of human embryos.

We investigated the association between single nucleotide polymorphisms (SNPs) in the frizzled (FZD) genes in the Wnt signal pathway and circulating osteoprotegerin (OPG), soluble receptor activator of NF-kappaB ligand (sRANKL) levels, bone turnover markers, and bone mineral density (BMD) in postmenopausal women. The SNPs in the FZD1, FZD5, FZD6, FZD7, and FZD9 genes were analyzed by direct sequencing in 371 postmenopausal Korean women. Levels of serum OPG, sRANKL, osteocalcin, C-telopeptide of type I collagen, calcium, parathyroid hormone and calcitonin, and BMD at the lumbar spine and femoral neck were measured. The SNPs in the FZD1, FZD5, FZD7, and FZD9 genes, and in exon 2 of the FZD6 gene were not observed. No significant differences in the adjusted BMD of lumbar spine and femoral neck and serum levels of OPG, sRANKL, and bone markers were noted among the single or haplotype genotypes of the L345M and E664A SNPs in the FZD6 gene and the distributions of these single or haplotype genotypes were not different according to the bone mass status. In conclusion, the polymorphisms of the FZD genes are not associated with BMD of the lumbar spine and femoral neck, bone turnover markers, or circulating OPG-sRANKL in Korean women.

PURPOSE: To describe the clinical experience and safety profile of a combination of 23-gauge and 20-gauge transconjunctival sutureless vitrectomy (TSV) METHODS: Thirty-seven eyes of thirty-seven consecutive patients who underwent 23-gauge combined with 20-gauge transconjunctival vitrectomy surgery by a single surgeon from August 2006 through December 2006 were reviewed retrospectively for surgical indications, wound problems, and postoperative complications. RESULTS: Thirty-seven eyes, including eyes with proliferative diabetic retinopathy (n=24), macular hole (n=3), epiretinal membrane (n=3), vitreous hemorrhage due to branch retinal vein occlusion and choroidal neovascular membrane (n=3), vitreous opacity secondary to uveitis (n=1), rhegmatogenous retinal detachment (n=1), and vitreoretinal traction syndrome (n=1), underwent operation. Seven eyes at 23-gauge sclerotomy sites and 15 eyes at 20-gauge sclerotomy sites had subconjunctival hemorrhage. Three eyes required sutures at 20-gauge sclerotomy sites intraoperatively due to wound leakage. One wound hemorrhage occurred at a 23-guage sclerotomy site. Vitreous hemorrhage (4 eyes), hyphema (2 eyes), and vitreous hemorrhage with hyphema (1 eye) occurred postoperatively. Postoperative hypotony, retinal detachment, and other complications did not occur. CONCLUSIONS: A combination of 23-gauge and 20-gauge transconjunctival sutureless vitrectomy which was created by modifying transconjunctival sutureless vitrectomy systems published previously guarded against sclerotomy wounds and a variety of vitreoretinal surgical indications.

Most extended care facilities have admitted both the healthy and unhealthy elderly, among which members' average caring demand vary. The Aged Welfare Law, however, currently provides no reasonable basis on the staffing policy for extended care facilities. It just reflects the admitted number of the elderly rather than differences in members' average caring demand among facilities. This study is designed to estimate the need for caring staff on the basis of the correlation between the individual health status measured by various tools including Activities of Daily Living and caring demand by actual service time for each one. The sample included all of the admitted elderly(187 persons) in 4 extended care facilities, two in Seoul and the other two in KangWon-Do over the survey period October 5 through October 20, 1996. The survey process consisted of 3 stages. (1) The current staffing information was collected through self-completed written questionnaires left for head official in each facility. (2) Six graduate students at School of Public Health interviewed all residents to collect information on their health status and sociodemographics. The response rate for the interview was relatively high(85%). (3) Information on direct and indirect caring time consumed for each residents came from self-completed written questionnaires given to nurses and helpers in each target facilities. Analysis of the data was made using Pearson's correlation and multiple regression technique through SAS program. Based on this procedure, the following was found. 1. No facility meet the staffing standard in the Aged Welfare Law completely. 2. It is actual service time that is most correlated with ADL(Activities of daily living). 3. When all of the elderly are divided by four groups based on the level of ADL, the mean values of needed caring time in each group are 15, 21, 36 and 88 minutes respectively. 4. There is no significant difference among facilities in distribution of elderly person by group. 5. No facility meets the estimated number of nurses and helpers which reflects health status of the admitted elderly. Therefore, it is required that severity of the admitted elderly be considered in establishing staffing standard for extended care facility.

OBJECTIVE: The objective of this study was to investigate whether serum levels of vascular endothelial growth factor (VEGF) measured at ovulation triggering day reflect ovarian response in intrauterine insemination (IUI) cycles. METHODS: Forty-nine infertile women who undergoing superovulation and IUI were included. Superovulation was performed using clomiphene citrate (100 mg/d on day 3~7) in combination with human menopausal gonadotropin (150 IU every other day starting on day 5). Serum samples were obtained on the day of hCG administration and the levels of VEGF-A and estradiol were measured. The numbers of mature follicle > or =17 mm in diameter were also counted. RESULTS: Serum VEGF-A levels did not correlate with the numbers of mature follicle count nor serum estradiol levels. Serum estradiol level was positively associated with mature follicle count. Serum VEGF-A levels tended to be lower in women with mature follicle count less than three or women with more than five. CONCLUSION: Our results indicate that serum VEGF-A levels do not have an association with superovulation outcome in IUI cycles. However, a tendency of lower VEGF-A level in poor and high responder suggests that those with extreme response to superovulation may be related with abnormal angiogenesis. Further studies should be warranted in larger populations.
