Filter by:The goal of the this study is to determine if Echinacea purpurea stimulates the immune system in children. For the study, 40 healthy children, 6-11 years old will be randomized to receive Echinacea purpurea or placebo for 10 days in 3 consecutive months. Blood samples will be obtained in the children just before starting study medication, during the first course of medication and either just prior to starting the second course of medication or 50 days following the last of the three courses of medication. Markers of immune activity in children receiving Echinacea or placebo will be compared.
To describe respiratory and laryngeal responses to laryngeal stimulation during propofol anesthesia in children with upper airway infections. To determine whether the co-administration of remifentanil blunts these reflex responses. To test whether the co-administration of remifentanil results in a significant reduction of apnea with laryngospasm in these patients. Hypotheses: I: In children with a URI undergoing anesthesia with propofol, the incidence of apnea and laryngospasm after controlled stimulation is expected to occur 2.5 times more frequently than in children without URI (20 vs. 8%). II: The incidence of apnea and laryngospasm is diminished after administration of remifentanil.
This is a four-year study, funded by the Center for Disease Control and Prevention, related to antimicrobial resistance in rural communities. The project consists of four components: A) surveillance of antimicrobial resistance, B) promotion of appropriate antimicrobial drug prescribing, C) preliminary assessment of the environmental impact of antimicrobials, and D) the development of new antimicrobial products. Six rural communities in Utah, and six rural communities in Idaho are participating in this study. Component D is being performed by investigators at Harvard University, under the direction of Co-Investigator Roger Inouye.
