Accuracy of oxygen tissue saturation values in assessing severity in patients with sepsis admitted to emergency departments.

Introduction: Near-infrared spectrometry assesses hemoglobin saturation of oxygen in tissues (StO2). Although it may provide additional information on local microcirculation function, the usefulness of near-infrared spectrometry in septic patients is debated. This study evaluated whether baseline StO2 value is useful in septic patients admitted to the emergency department with a diagnosis of severe sepsis.

Management of Hodgkin's and non-Hodgkin's lymphomas.

These diseases of the lymphoreticular system with neoplastic alteration of the involved tissues represent different entities and show marked variability in their clinical manifestations, pathologic behavior, prognosis, and response to treatment. New diagnostic, histopathologic, and therapeutic concepts in the past decade have led to significant advances in the care and management of these patients, particularly those with Hodgkin's disease.
