Computed tomography (CT) was performed in 54 patients with hepatocellular carcinoma three weeks after trans catheter arterial chemotherapy using iodized oil and doxorubicin with or without gelfoarn embolization. Patients with iodized oil retention in the tumor greater than 50 per cent of tumor size survived longer than patients with retention of less than 50 per cent. Differences were also found within Okuda stages I and II, but they were significant only in Okuda stage I (p
A stenosis of a side-to-side splenorenal shunt was treated by percutaneous angioplasty two years after the performance of the shunt. After dilatation, there was a fall of the splenorenal pressure gradient from 28 to 17 cm H 2 0 and good transanastomotic flow was re-established. As in other arterial and venous territories, angioplasty may be an interesting alternative to surgery.
Introduction Legionella micdadei are gram-negative bacilli living in soil and aquatic habitats. They are responsible for less than 10% of legionellosis, but have a propensity to affect people suffering from immunodeficiency. Lung cavitations may also occur in this population. Isolation of L. micdadei on clinical samples requires specific culture media that are not routinely used. Moreover, serologic methods and urinary assays are specific for Legionella pneumophila serogroup 1 (the most frequent serogroup isolated from clinical specimens), and lack sensitivity for diagnosing L. micdadei infection. As a consequence, this diagnosis is difficult to confirm. Case report We report here a severe case of community-acquired legionellosis due to L. micdadei, in a patient under immunosuppressive medications and high-dose corticosteroids for rheumatoid arthritis. The source of his infection was hypothesized to be his continuous positive airway pressure device, which was regularly cleaned with tap water instead of sterile water, thus potentially resulting in Legionella contamination. Conclusions L. micdadei must be considered as a possible cause of community-acquired severe pneumonia in case of immunodeficiency. For outpatients, advice concerning the cleaning of aerosolsgenerating devices at home must be emphasized.
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.
