Assessment of Aspergillus-specific T cells for diagnosis of invasive aspergillosis in a leukemic child with liver lesions mimicking hepatosplenic candidiasis.

A child with acute myeloid leukemia presented with multiple liver lesions mimicking hepatosplenic candidiasis during the neutropenic phase following the induction chemotherapy. All the available diagnostic tools showed repeatedly negative results, including galactomannan. An enzyme-linked immunospot (ELISPOT) assay showed a high number of Aspergillus-specific T cells producing interleukin-10 [TH2(IL-10)] and a low number of Aspergillus-specific T cells producing gamma interferon [TH1(IFN-gamma)], revealing invasive aspergillosis (IA) before the confirmatory biopsy.

Low-molecular-weight heparin for vertebral artery dissection.

A case of vertebral artery dissection and consequent basilar artery thrombosis in a 6-year-old patient is reported. The patient was treated with subcutaneous low-molecular-weight heparin at therapeutic doses (enoxaparin, 100 IU/kg twice daily) for 3 weeks, then reduced to 2,000 IU/day for 3 more weeks. After this time a magnetic resonance angiogram was obtained that showed complete recanalization of the left basilar artery.
