Abstract
8117 Monoclonal gammopathy of undetermined significance (MGUS) increase in prevalence with age and it is associated with risk of progression to plasma cell disorder. According to ASH guidelines, patients (pts) should have a complete blood count (CBC), creatinine, calcium, and a complete bone survey and periodic follow up. There has been no clear-cut guideline regarding the role of bone marrow biopsy in these patients. There is suggestion in the literature that bone marrow aspiration and biopsy is indicated if the M protein is 1.5 g/dL. Hypothesis We hypothesize that the increase in serum immunoglobulin is correlated with an increase in plasma cell in the bone marrow biopsy. Methods: We performed a retrospective chart review of 327 MGUS veteran patients seen from 2002 to 2005. Diagnostic criteria for MGUS were defined as <3 g/dL serum monoclonal protein, <10 % plasma cells in the bone marrow and absence of radiographic or laboratory abnormality related to the plasma cell proliferative process. Patients with smoldering myeloma were excluded. Bone marrow biopsies were available on 97/327 patients. Bone marrow biopsy with plasma cell percentage, serum protein electrophoresis (SPEP) and immunofixation (SFE), and immunoglobulin levels of these patients were retrieved and statistical analysis was performed by using Pearson correlation coefficient and linear regression analysis to detect the correlation between plasma cell percentage and immunoglobulin levels. Results: Of the 97 patients whom the bone marrow biopsy was available, 66 patients had IgG, 15 had IgA and 16 had IgM monoclonal paraprotein. There was linear correlation between serum IgG and IgA levels with the percentage of plasma cells in the bone marrow. (p< 0.001 and < 0.02 respectively. By regression analysis, using a cut off value of 10% plasma cells in the bone marrow, the predicted level of IgG and IgA immunoglobulin was 2124 mg /dl and 1564 mg/dl respectively. There was no correlation between IgM immunoglobulin and plasma cell percentage in the marrow. Conclusion: There is a linear correlation between serum IgG and IgA immunoglobulin with plasma cell percentage in the bone marrow. Bone marrow biopsy with plasma cell percentage of 10% or higher may be predicted in patients with MGUS with IgG or IGA above 2g/dl and 1.5g/dl respectively. No significant financial relationships to disclose.

Abstract
The antiseptic effectiveness and acceptability of a commercial alcohol-based waterless (ABWL) and an alcohol-based water-aided (ABWA) scrub solution were compared with a brush-based iodine solution (BBIS) under conditions encountered in community hospital operating rooms. This randomized partially blinded study was based on guidelines from the American Society for Testing and Methods. The three scrub solutions were compared for antimicrobial efficacy, using criteria within the Food and Drug Administration's Tentative Final Monograph for Healthcare Antiseptic Products (FDA-TFM), and for participants' acceptance of the products. Volunteer surgical staff that worked daily in the same operating room for the entire duration of the study were enrolled. In total, 1126 surgical scrub procedures were performed over the duration of the study. Only the ABWL met all of the FDA-TFM criteria. The BBIS performed better than both of the alcohol-based solutions at the end of Day 1 (P=0.03), but the ABWL was more efficacious than the ABWA and the BBIS at the end of Days 2 and 5 (P=0.02 and 0.01, respectively). When colony-count reductions were compared over the entire duration of the study, there was no significant difference between the three solutions (P=0.2). The participants found the ABWL easiest to use (P<0.001), with the fewest adverse effects on skin (P=0.007), and it was their preferred product (P<0.001). Although both of the commercially available alcohol-based solutions may be considered as acceptable alternatives to the BBIS for presurgical antisepsis, the ABWL was found to have significantly higher user acceptability.

Abstract
18533 Background: Patients with stage IV lung cancer have median survival of 4–6 months. Randomized trials have shown chemotherapy may have small but significant survival benefit. To achieve this small gain,patients may have to spend their last few days of life in the office visits and hospitalization. Last few days of person’s life need to be spent comfortably and most effective manner in accordance to their wishes, desires and priorties.We attempted to study the “Time Lost” in the stage IV lung cancer patients who either did not choose or were not offered the palliative care/Hospice. Methods: We retrospectively reviewed charts of patients diagnosed with stage IV lung cancer (at their initial presentation) from Jan 2002 to Dec 2005 at our institution. We calculated their inpatient and out patient visit hrs and hence “Time Lost” during the last few days of their life. Patients were divided into two groups—Group A (n = 12): Patients who opted to choose palliative/hospice care immediately after the diagnosis and GroupB (n = 46): Patients who either refused or were not offered palliative/hospice care. Results: The median age at diagnosis was similar in both groups (71 vs 69.5 yrs). The median survival was also similar in both groups (4 months vs 4 months). Patients in group B (non hospice) had 1 month “Lost Time” out of their median survival of 4 months. In comparison patients in group A (hospice) had median survival of 4 months with “No Lost Time”. Thus patients who were not offered hospice or refused hospice spent 25% of their precious time during last stages of their life in inpatient stays and outpatient visits. Conclusions: Patients with stage IV lung cancer should be actively offered palliative/Hospice care, though studies with large number of patients is further required.
