Over 13 years, we have seen 16 cases of proven invasive aspergillosis in 446 bone marrow transplant recipients, an incidence of 3.6%. The incidence of infection is low in patients with uncomplicated allogeneic or autologous bone-marrow transplants (< 2% and 0, respectively). Of the 16 episodes following transplantation, 10 occurred in patients with late transplant complications who were no longer in protective isolation. In patients who had focal pulmonary lesions (as diagnosed by computed tomographic scanning), culture of bronchoalveolar lavage (BAL) fluid was not an effective diagnostic procedure. In diffuse pulmonary disease due to Aspergillus, culture of BAL fluid had a sensitivity of 100%. Aspergillus species were isolated from an additional six patients who had no evidence of invasive aspergillosis. Graft rejection was a significant predisposing factor for the development of invasive aspergillosis (P < .001, log-rank test), and in our hospital, these patients now receive intravenous amphotericin B as prophylaxis. None of the six patients whose chest roentgenograms showed abnormalities before transplantation and who underwent surgical resection as part of the treatment for invasive aspergillosis developed recurrent infection.

Unlike previous reports this study did not show that allopurinol had a cardioprotective effect in patients with good left ventricular function undergoing elective coronary artery surgery.

Malignant pleural mesothelioma (MPM) is a primary and locally aggressive tumor of the pleura. A well defined causal relationship with asbestos exposure, and an overwhelming media interest in the use of asbestos in industrialized countries after World War II, has produced a high level of awareness of this disease. With a peak incidence of MPM expected in Europe, Australia, and the US within the next 15 years, and the failure of current treatment approaches to offer long-term survival and improve quality of life, new therapeutic regimens are warranted. The effects of surgery in terms of survival and symptomatic relief have yet to be defined because of a lack of randomized trials. The role of radiotherapy in the treatment of MPM remains controversial, as the radiosensitivity of malignant mesothelial cells is modest. MPM response to chemotherapy is comparatively poor. The combination of pemetrexed and cisplatin chemotherapy has achieved the best objective responses. Presently, a multimodal approach is considered to be the cornerstone of treatment of MPM. Important ongoing international and national trials are addressing the roles of chemotherapy (e.g. the EAP and MS01 trial), radical surgery (e.g. the MARS trial) and radiotherapy (e.g. the SAKK group phase III study).

LD filtration during CABG reduced the number of cerebral microemboli recorded by TCD and showed a strong trend towards improving NP performance post-operatively. These findings suggest that the use of such filters in CABG surgery may offer increased neuroprotection.
