  ABSTRACT: This study was done to compare the rates of hemolysis and repeated sampling in blood samples obtained by a syringe needle versus a vacuum tube needle. A randomized, prospective study was used to evaluate the differences between the two blood sampling methods. The study group consisted of patients seen in the emergency department (ED) for blood sampling to determine electrolyte level. ED patients were randomly assigned to either the syringe group or the vacuum tube group. All blood samples were collected by experienced ED nurses and hemolysis was determined by experienced laboratory technologists. Data were analyzed using Fisher's exact test and binary logistic regression. One hundred forty-five valid samples were collected (74 in the syringe group versus 71 in the vacuum tube group). 5 of 74 (6.8%) blood samples in the syringe group and 8 of 71 (11.3%) in the vacuum tube group hemolyzed. Repeated blood sampling occurred for 2 of 74 (2.7%) and 3 of 71 (4.2%) in each group respectively. There were no significant differences in rates of hemolysis and repeated sampling between two groups (B=1.97, p=.204; B=2.36, p=.345). Venipuncture with syringe needles can be recommended for ED nurses to obtain blood samples.

  ABSTRACT: Brain metastasis from epithelial ovarian carcinoma (EOC) is managed by a multimodal treatment approach. Thus, to determine the prognostic factors associated with this situation is important for management decisions regarding the type of treatment and aggressiveness of treatment. From 1995 to 2005, 13 patients with brain metastases resulting from EOC underwent treatment at Samsung Medical Center. We retrospectively reviewed the medical records to determine prognostic factors and to evaluate treatment outcome. The median age at diagnosis for primary ovarian carcinoma and brain metastasis was 52 and 55 years, respectively. Median interval to brain metastases was 28 months after the diagnosis of EOC. At the time of analysis, nine patients had died of disease. The median survival from brain relapse was 7 months. A Karnofsky performance status of 70 or higher, primary control, solitary brain lesions, recursive partitioning analysis (RPA) class, and treatment modality including gamma-knife radiosurgery (GKRS) were related to survival on univariate analyses. Multivariate analysis showed that treatment modality including GKRS was a more important prognostic factor than RPA class (P = 0.04). This small series demonstrated that GKRS can be a valuable modality for the management of brain metastasis in patients with EOC. Therefore, a better outcome can be achieved by choosing GKRS in their treatments in selected patients.
