Comparative Study Controlled Clinical TrialThe diagnostic value of C-reactive protein, interleukin-8, and monocyte chemotactic protein in risk stratification of febrile neutropenic children with hematologic malignancies.
Recent advances in febrile neutropenia have highlighted the value of risk stratification especially that it can have important implications in terms of management. We aimed to identify a serum marker that may help to stratify febrile neutropenic pediatric patients treated for hematologic malignancies at the time of first evaluation. Thus, C-reactive protein (CRP), interleukin-8 (IL-8), and monocyte chemotactic protein-1-alpha (MCP-1-alpha) were evaluated for their predictive and diagnostic relevance in febrile episodes of cancer patients. ⋯ Low levels of CRP, MCP-1, and IL-8 could identify patients with unexplainable fever; whereas, high levels of these markers were of help in the diagnosis of infectious episodes. A model combining more than 1 marker is recommended in the assessment of febrile neutropenia.

Case ReportsIs the use of rFVIIa safe and effective in bleeding neonates? A retrospective series of 8 cases.
Recombinant activated factor VII (rFVIIa), originally developed for the treatment of life-threatening bleeding in hemophilic patients with inhibitors to factors VIII or IX, has been increasingly used to control hemorrhage unresponsive to conventional treatment, in the absence of a defined coagulopathy or thrombocytopathy. To date, clinical experience of rFVIIa administration in neonates, especially preterms, is rather limited, because of the lack of controlled studies and based solely on some published case reports and 1 prospective pilot study. The objective of this study was to retrospectively evaluate the clinical outcome of newborns treated with recombinant activated factor VII for intractable bleeding or severe coagulation disturbances, resistant to conventional hemostatic therapy. ⋯ In this study, the hemostatic agent rFVIIa was well-tolerated and behaved in a safe and efficacious manner in all infants treated for life-threatening bleeding and coagulation disorders. Future prospective controlled trials are needed to determine the efficacy, safety, tolerability, and possibly the optimal dose and timing of rFVIIa administration.

Case ReportsAcute encephalopathy and cerebral vasospasm after multiagent chemotherapy including PEG-asparaginase and intrathecal cytarabine for the treatment of acute lymphoblastic leukemia.
A 7-year-old girl with an unusual reaction to induction chemotherapy for precursor B-cell acute lymphoblastic leukemia (ALL) is described. The patient developed acute encephalopathy evidenced by behavioral changes, aphasia, incontinence, visual hallucinations, and right-sided weakness with diffuse cerebral vasospasm on magnetic resonance angiography after the administration of intrathecal cytarabine. Vincristine, dexamethasone, and polyethylene glycol-asparaginase were also administered before the episode as part of induction therapy. Neurologic status returned to baseline within 10 days of the acute event, and magnetic resonance angiography findings returned to normal 4 months later.
