Randomized, paired comparison of No-Sting Barrier Film versus sorbolene cream (10% glycerine) skin care during postmastectomy irradiation.

PURPOSE: Postmastectomy irradiation provides an excellent model for irradiated skin care practices because of the relatively uniform surface and radiation compared with other situations in which radiation-induced moist desquamation is common. We designed a study to test the effect of prophylactic 3M Cavilon No-Sting Barrier Film (No-Sting) on the rates of moist desquamation compared with sorbolene cream (with 10% glycerin). METHODS AND MATERIALS: The irradiated chest wall was divided into medial and lateral halves. Sixty-one women were randomized to have No-Sting applied to either the medial or lateral half, with the alternate half treated with sorbolene. RESULTS: For all patients, the skin toxicity, calculated as the area under the curve, mean No-Sting and sorbolene score was 8.1 vs. 9.2, respectively (p = 0.005, Wilcoxon signed rank test). The total number of weeks of moist desquamation for the 61 patients was 40 vs. 45, equating to a mean of 0.65 week vs. 0.74 week per patient in the No-Sting and sorbolene-treated areas, respectively. The rates of moist desquamation were 33% vs. 46% (p = 0.096, McNemar's Exact test). For 58 fully assessable patients (minimum of 7 weekly observations), the area under the curve and rates of moist desquamation were significantly different statistically (p = 0.002 and 0.049, respectively). No statistically significant differences were noted in the pain scores. The pruritus scores were significantly reduced in the No-Sting area (area under the curve, p = 0.011). CONCLUSION: No-Sting reduces the duration and frequency of radiation-induced moist desquamation.

Oceanicaulis alexandrii gen. nov., sp. nov., a novel stalked bacterium isolated from a culture of the dinoflagellate Alexandrium tamarense (Lebour) Balech.

Five bacterial strains were isolated from a non-toxigenic strain of the marine dinoflagellate Alexandrium tamarense (Lebour) Balech CCMP 116 (NEPCC C116), during a survey of the diversity of bacteria associated with paralytic shellfish toxin-producing cultures of Alexandrium spp. (Dinophyta). All strains were strictly aerobic, Gram-negative, straight or curved rods. Cells were dimorphic, with stalks (or prosthecae) and non-motile or non-stalked and motile, by means of a single polar flagellum. The bacteria grew best at salt concentrations ranging from 2 to 10 % and growth occurred at 10 degrees C, but not at 50 degrees C. The G+C content of the chromosomal DNA of the strains was determined to be 61-62 mol%. Major cellular fatty acids of the bacteria presented a unique profile. 16S rRNA gene sequence analysis showed the five strains to be related to genera of budding bacteria of marine origin in the 'Alphaproteobacteria', namely, Hirschia, Maricaulis and Hyphomonas, although they exhibited substantial differences in morphology, substrate utilization and fatty acid profile to members of these genera. The five strains are proposed to comprise a new species of a new genus, Oceanicaulis alexandrii gen. nov., sp. nov., the type strain of which is C116-18(T) (=DSM 11625(T)=NCIMB 13905(T)).

Evaluability assessment. A catalyst for program change and improvement.

Using a local cross-cultural health service program as a framework, the authors describe the process of an evaluability assessment (EA) and illustrate how it can be a catalyst for program change. An EA is a process that improves evaluation. The key product was a logic model, which traces the links between objectives, activities, and outcomes. Four key insights emerged. First, the distinction of who was included and excluded in the target population, originally ambiguous, was clearly defined. Second, through the development of the logic model, staff members were able to analyze their goals and assumptions and critically explore possible gaps between expected outcomes and activities. Third, the EA enabled reflection on and clarification of both process and outcome measures. Finally, global goals were pared down to better match the project capacity. Developing an evaluability assessment was a cost-effective way to collaborate with staff to develop a clearer, more evaluable project.

Organizational readiness for telemedicine: implications for success and failure.

The use of telemedicine brings about change in health-care organizations and opens up new possibilities for service delivery. The organizational environment is often crucial in determining whether or not telemedicine applications will be successful. To examine the concept of 'organizational readiness for telemedicine' as a factor to explain why telemedicine initiatives succeed or fail, the results were used of interviews with key informants, conducted in two studies: the Alliance for Building Capacity project and the National Initiative for Telehealth guidelines project. The data indicate that organizational readiness for telemedicine is a multifaceted concept that is related to planning and the workplace environment. A greater understanding of the factors within organizational readiness could help to avoid costly implementation errors. 'Readiness' needs to be systematically assessed and is important for long-term success.
