Single-cell cytokine profiles in normal humans: comparison of flow cytometric reagents and stimulation protocols

by

Abstract

Cytokines are produced and function at a micro environmental level: intracellular assessment has only recently become practically feasible. We used 3-color flow cytometry to examine surface and cytoplasmic antigens on peripheral blood lymphocytes of 18 normal donors, assessing the applicability/comparability of various directly conjugated anti-human cytokine reagents and stimulation protocols using separated cells or whole blood preparations.… Read more

Staphylococcus aureus bloodstream infections among patients undergoing electroconvulsive therapy traced to breaks in infection control and possible extrinsic contamination by propofol

by

Abstract

Infectious complications associated with electroconvulsive therapy (ECT) are extremely unusual. When five of nine patients undergoing ECT at one facility on June 20, 1996 developed Staphylococcus aureus bloodstream infection (BSI), an investigation was initiated. A retrospective cohort study, a procedure review, and observational and microbiologic studies were performed.… Read more

The cost of selected tuberculosis control measures at hospitals with a history of Mycobacterium tuberculosis outbreaks

by

Abstract

OBJECTIVE: To determine the cost of nonrespirator-related tuberculosis (TB) control measures at several hospitals, following publication of the Centers for Disease Control and Prevention (CDC)’s revised TB infection control guidelines.

DESIGN: Infection control (IC) and TB coordinators obtained cost information on tuberculin skin-test (TST) programs, addition of IC and employee health service (EHS) personnel, and the retrofit or new construction of environmental controls.… Read more
