Bloodstream infection caused by nontoxigenic Corynebacterium diphtheriae in an immunocompromised host in the United States.

Corynebacterium species are well-known causes of catheter-related bloodstream infections. Toxigenic strains of Corynebacterium diphtheriae cause respiratory diphtheria. We report a bloodstream infection caused by a nontoxigenic strain of C.

Concomitant psychotropic medication use during treatment of schizophrenia patients: longitudinal results from the CATIE study.

Objective: This study is a post hoc analysis of additions of antidepressants, anxiolytics, and sedative/hypnotics in treatment of patients randomized to antipsychotic treatment in the CATIE study, which recruited a chronic, "real world" schizophrenia sample and followed patients for up to eighteen months. We examined baseline predictors of initiation, time until initiation, and duration of treatment with antidepressants, anxiolytics, and sedative/hypnotics in CATIE study participants.

Methods: Psychotropic medication use by 1,449 CATIE study participants was documented at each study visit.

Treatment outcomes of patients with tardive dyskinesia and chronic schizophrenia.

Objective: We compared the response to antipsychotic treatment between patients with and without tardive dyskinesia (TD) and examined the course of TD.

Method: This analysis compared 200 patients with DSM-IV-defined schizophrenia and TD and 997 patients without TD, all of whom were randomly assigned to receive one of 4 second-generation antipsychotics. The primary clinical outcome measure was time to all-cause treatment discontinuation, and the primary measure for evaluating the course of TD was change from baseline in Abnormal Involuntary Movement Scale (AIMS) score.
