Multicenter Study Clinical TrialTemozolomide after radiotherapy for newly diagnosed high-grade glioma and unfavorable low-grade glioma in children.
Chemotherapy is commonly used in the treatment of children with high-grade glioma, although its usefulness is uncertain. We conducted a multi-institutional study to evaluate the efficacy of temozolomide given after radiotherapy in children with newly diagnosed high-grade glioma and unfavorable low-grade glioma (gliomatosis cerebri or bithalamic involvement). Optional window therapy of intravenous irinotecan (10 doses of 20 mg/m2 per cycle x 2) was given over 6 weeks. ⋯ Twenty-three patients received 112 cycles of temozolomide therapy. The 2-year progression-free and overall survival estimates were 11 +/- 5% and 21 +/- 7%, respectively. Although the heterogeneity of prognostic factors in our patients made assessment of treatment outcome more difficult, the addition of 6 cycles of temozolomide after radiotherapy did not seem to alter the poor outcome of these patients.

Multicenter StudyEffectiveness of endoscopy in patients admitted to the intensive care unit with upper GI hemorrhage.
Esophagogastroduodenoscopy (EGD) is generally indicated for the management of patients admitted to intensive care units (ICUs) with upper gastrointestinal (GI) hemorrhage but its impact in community practice has not been measured. Thus, the effectiveness of 3 EGD factors, viz., accurate initial diagnosis, performance within 24 hours of admission (early EGD), and appropriate intervention, was examined. ⋯ Early, accurate EGD with appropriate therapeutic intervention is effective as practiced in the community and is associated with improved outcomes for patients with upper GI hemorrhage admitted to the ICU. Inaccurate diagnosis at initial EGD is uncommon but has a significant adverse association with all outcome measures.
