BACKGROUND Near-infrared spectroscopy estimates soft-tissue oxygenation approximately 2 to 3 cm below the skin. The purpose of the present study was to evaluate muscle oxygenation in the setting of an acute compartment syndrome of the leg and to determine if near-infrared spectroscopy is capable of detecting perfusion deficits. METHODS Fourteen patients(More)
Herein, we describe a combination of clinical, microbiologic, and histopathologic findings significantly associated with osteomyelitis in chronic granulomatous disease. When present, these features should raise the suspicion of underlying chronic granulomatous disease. In patients with these findings, anti-infective prophylactic measures aiming to cover(More)
BACKGROUND Near-infrared spectroscopy measures the percentage of hemoglobin oxygen saturation in the microcirculation of tissue up to 3 cm below the skin. The purpose of this study was to describe the measurable response of normal tissue oxygenation in the leg after acute trauma with use of this technique. METHODS Twenty-six patients with acute unilateral(More)
BACKGROUND Hemorrhage from esophageal varices remains a substantial management problem. Endoscopic sclerotherapy was preferred for more than a decade, but fluoroscopically placed intrahepatic portosystemic stents have recently been used with increasing frequency. OBJECTIVE To compare sclerotherapy with transjugular intrahepatic portosystemic shunt (TIPS)(More)
BACKGROUND The rate and degree of LDL cholesterol reduction, in the first 2 weeks of therapy, may relate to the early benefit of hydroxymethyl glutaryl coenzyme A reductase inhibitor therapy. In patients with similar baseline LDL cholesterol levels as in the Cholesterol and Recurrent Events (CARE) trial, we report the results of a 2-week placebo-controlled,(More)
BACKGROUND Near infrared spectroscopy (NIRS) has been suggested as a possible means for detecting perfusion deficits in patients with acute compartment syndrome (ACS). STUDY OBJECTIVES To longitudinally examine NIRS in an ACS model to determine its responsiveness to decreasing perfusion pressure. METHODS A NIRS sensor pad was placed under a tourniquet(More)
Liver tumors are rare in children, and their diagnoses may be challenging particularly because of the lack of a current consensus classification system. Systematic central histopathological review of these tumors performed as part of the pediatric collaborative therapeutic protocols has allowed the identification of histologic subtypes with distinct(More)
Hepatoblastoma, a childhood tumor of the liver, is composed of epithelial and mesenchymal elements in varying proportions and at various stages of differentiation. The epithelial element recapitulates the stages of hepatocyte development from the primitive blastema through embryonal hepatocytes to fetal hepatocytes. The blastemal or undifferentiated cells(More)
BACKGROUND The objectives of this prospective study were to avoid adjuvant treatment for patients with intraocular disease and patients with postlaminar optic nerve invasion (PL-ONI) without full choroidal or scleral invasion. Adjuvant chemotherapy (Regimen 1) was given to patients with scleral invasion, PL-ONI without cut section, and full choroidal and/or(More)
