The European Organization for Research and Treatment of Cancer and the Mycosis Study Group (EORTC-MSG) radiological definitions of invasive pulmonary aspergillosis (IPA) may lack diagnostic sensitivity. We evaluated applying less restrictive radiological criteria, when supported by specific microbiological findings, to define IPA in acute myeloid leukaemia (AML), lymphoproliferative diseases (LD) and allogeneic stem cell transplant (allo-SCT) patients. Overall, 109 consecutive episodes of proven/probable IPA in 56 AML, 31 LD and 22 allo-SCT patients diagnosed from February 2006 through to January 2011 were considered. IPA was diagnosed with EORTC-MSG criteria (control group, 76 patients) or without prespecified radiological criteria (study group, 33 patients). The latter differed from the former by the inclusion of patients with pulmonary infiltrates not fulfilling the three EORTC-MSG IPA specific findings of dense, well-circumscribed lesions with or without halo sign, air crescent sign or cavity. All the analysed clinical and mycological characteristics, 3-month response to antifungal therapy and 1- and 3-month cumulative survival were comparable in the control and study groups in AML, LD and allo-SCT patients. Seventeen of 33 (51.5%) patients of the study group fulfilled EORTC-MSG radiological criteria at subsequent imaging performed a median of 15 days (range, 6-40 days) after documentation of the pulmonary infection. Our study seems to confirm the possibility of revising the EORTC-MSG criteria by extending the radiological suspicion of IPA to less specific chest computerized tomography scan findings when supported by microbiological evidence of Aspergillus infection in high-risk haematological patients.
The adrenal gland is a common site of a large spectrum of abnormalities like primary tumors, hemorrhage, metastases, and enlargement of the gland from external hormonal stimulation. Most of these lesions represent nonfunctioning adrenal adenomas and thus warrant a conservative management. Multi-detector computed tomography (CT) and magnetic resonance (MR) imaging are still considered highly specific and complementary techniques for the detection and characterization of adrenal abnormalities. Radiologist can establish a definitive diagnosis for most adrenal masses (i.e., carcinoma, hemorrhage) based on imaging alone. Imaging therefore can differentiate malignant lesions from those benign and avoid unnecessary aggressive management of benign lesions. The article gives an overview of the adrenal lesions and their imaging characteristics seen on CT and MR imaging.
Several severe complications may be associated with the use of central venous catheters (CVC). We retrospectively evaluated on a large cohort of patients the incidence of CVC-related early and late complications. From 7/99 to 12/2005, 1102 CVC have been implanted at our Institution in 881 patients with hematological malignancies (142,202 total day number of implanted CVC). Early mechanic complications were 79 (7.2% - 0.55/1,000 days/CVC). Thirty-nine episodes of early infective complications (<1 week from CVC implant) occurred (3.5% - 0.3/1000 days/CVC): furthermore, 187 episodes of CVC-related sepsis (17% - 1.3/1000 days/CVC) were recorded. There were 29 episodes (2.6%) of symptomatic CVC-related thrombotic complications, with a median interval from CVC implant of 60 days (range 7 – 395). The rate of CVC withdrawal due to CVC-related complications was 26%. The incidence of CVC-related complications in our series is in the range reported in the literature notwithstanding cytopenia often coexisting in hematological patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
