Reverse Seroconversion of Hepatitis B following Allogenic Hematopoietic Stem Cell Transplantation from a Hepatitis Immune Donor in a Multiple Myeloma Patient / 대한혈액학회지

A 52-yr-old male with multiple myeloma underwent autologous stem cell transplantation in June 2002. In August 2004, the multiple myeloma had recurred. The patient received allogenic stem cell transplantation in September 2005. Before undergoing transplantation, the presence of HBsAb and the absence of HBsAg were noted. The patient underwent allogenic peripheral blood stem cell transplantation (PBSCT) from a sibling donor who was hepatitis surface antibody (HBsAb) positive and hepatitis surface antigen (HBsAg) negative. Nineteen months after the PBSCT, the liver function tests showed elevation of the aminotransferases. The patient was HBsAg positive and HBsAb negative. The liver biopsy specimen revealed hepatitis. The reactivation of a hepatitis B virus infection, in a hepatitisB immune patient, referred to as reverse seroconversion, is a rare complication of hematopoietic stem cell transplantation.

A Hospital-based Tabletop Exercise for Pandemic Influenza Preparedness: Design and Evaluation

BACKGROUND: To evaluate the usefulness and compliance of a hospital-based tabletop exercise in setting of pandemic influenza in hospitals. MATERIALS AND METHODS: Tabletop exercise was held in Pusan National University Hospital and forty two hospital employees were invited to participate in the exercise. The scenario for hospital-based tabletop exercise was designed. It consisted of three modules, which simulated the influx and outbreak of H5N1 influenza that was epidemic in Southeast Asia. Pre-, post-exercise surveys were completed by anonymous questions. RESULTS: Thirty-seven (88%) of 42 invited participants attended exercise. All members of the administration group and the ancillary services group participated. But, only 77% members of the clinical services group participated. In pre-exercise survey, priorities of eight goals regarding skills and knowledge during exercise were inquired., The highest priorities pointed out by the respondents were "Increase the knowledge of pandemic influenza" (22%), "Development of strategies for optimal communication among employees within specific department" (19%) and "Development of strategies for improved coordination between facilities within the health system" (19%). Twenty-one (57%) of participants completed the post-exercise surveys. At post-exercise surveys, 81% of the participants stated that the tabletop exercise was extremely or very useful, 86% of the participants also stated that it increased their knowledge of pandemic influenza. CONCLUSION: Tabletop exercise is an effective modality for increasing pandemic influenza preparedness in hospitals, and this method is useful for guiding preparedness activities within the hospital environment. Further studies to determine the appropriate method of discussion, questionnaire, duration of exercise and injection are needed.
