ABSTRACT: Bone marrow examination (BME) represents an essential tool for diagnosis and monitoring of haematological disorders. It remains associated with morbidity and discomfort; repeat examinations are frequent. We made a single-centre prospective survey on 700 BME between July 2007 and July 2008 with a structured anonymized questionnaire for patients undergoing and physicians performing BME, which includes at our institution always aspiration and trephine. All procedures were performed according to institutionalised standard operating procedures; 412 patients' (58.9%) and 554 physicians' (79.1%) questionnaires were returned. Pain was the only procedure-related complication; no pain was reported in 149 (36.7%), bearable pain in 242 (59.6%) and unbearable pain in 15 (3.7%) cases. Premedication associated complications were reported by 110 (32.7%) of the 336 (65.4%) patients with premedication before BME. None of these were > WHO grade 2; most frequently reported were tiredness (76 patients; 22.6%), dizziness (19 patients; 5.7%) and nausea (15 patients; 4.5%). Only two factors were significantly associated with unbearable pain: "pain during prior BME" (seven of 94 with versus one of 198 without previous pain; p < 0.01) and "information before BME" (four of 11 without versus 12 of 372 with adequate information before BME; p < 0.01). Inadequate information at any time showed a trend towards an association with unbearable pain (p = 0.08). No other factor was associated with unbearable pain. Good and adequate information appears to be the best way to reduce pain, even for a future BME.

ABSTRACT: Nursing in 'live islands' and routine high dose intravenous immunoglobulins after allogeneic hematopoietic stem cell transplantation were abandoned by many teams in view of limited evidence and high costs.
This retrospective single-center study examines the impact of change from nursing in 'live islands' to care in single rooms (SR) and from high dose to targeted intravenous immunoglobulins (IVIG) on mortality and infection rate of adult patients receiving an allogeneic stem cell or bone marrow transplantation in two steps and three time cohorts (1993-1997, 1997-2000, 2000-2003).
Two hundred forty-eight allogeneic hematopoetic stem cell transplantations were performed in 227 patients. Patient characteristics were comparable in the three cohorts for gender, median age, underlying disease, and disease stage, prophylaxis for graft versus host disease (GvHD) and cytomegalovirus constellation. The incidence of infections (78.4%) and infection rates remained stable (rates/1000 days of neutropenia for sepsis 17.61, for pneumonia 6.76). Cumulative incidence of GvHD and transplant-related mortality did not change over time.
Change from nursing in 'live islands' to SR and reduction of high dose to targeted IVIG did not result in increased infection rates or mortality despite an increase in patient age. These results support the current practice.

ABSTRACT: OBJECTIVE: The aim of this study was to optimize detection of angioinvasive pulmonary aspergillosis by showing direct vessel involvement at a peripheral level with high-resolution MDCT angiography in patients with antibiotic-resistant fever of unknown origin under immunosuppression. Twelve CT angiographic examinations were prospectively performed in 10 patients with an optimized CT angiography protocol with 16-MDCT after IV administration of contrast agent using care bolus (Siemens Medical Solutions). Axial images and maximum intensity projections were evaluated for vascular occlusion by an experienced radiologist blinded to the clinical histories. Results were correlated with histology and clinical follow-up data including follow-up CT. Fourteen focal pulmonary lesions were detected by CT in eight patients. Eight of 14 lesions were confirmed by histology. In the remaining six lesions, diagnosis was made by clinical and CT follow-up. In nine of nine lesions in which angioinvasive infection was excluded, CT angiography showed patent vessels. In four of five lesions with histologically proven fungal angioinvasion, vascular occlusion was detected on CT angiography. CONCLUSION: High-resolution MDCT angiography has been shown to be a feasible technique to depict directly vessel occlusion in the setting of suspected fungal infections, especially for early diagnosis of angioinvasive pulmonary aspergillosis in immunosuppressed patients.

ABSTRACT: Leukemias include a variety of acute and chronic malignant hematological diseases that require antineoplastic chemotherapy. Hematological stem cell transplantation allows an aggressive chemotherapy during which patients suffer from severe immunosuppression. Oral infections may cause serious complications during this immunosuppression. Therefore, professional diagnosis and elimination of oral infection foci must be carried out as early as possible before such treatment. Aggressive chemotherapy causes hyposalivation and as a consequence an increased risk for oral hard and soft tissue diseases. Adequate oral care before, during and after chemotherapy combined with a stem cell transplantation is necessary to prevent oral diseases and systemic complications of oral origin.
