Electromyographic diagnosis of multifocal pyomyositis.

Introduction: Multifocal pyomyositis is a rare inflammatory myopathy caused by bacterial infection and abscess formation in multiple skeletal muscles. To date, electromyography (EMG) of pyomyositis has not been reported.

Methods: We describe the EMG findings of a patient with pathologically proven multifocal pyomyositis.

The relationship between dialysis performance measures: adequacy and anemia management.

Background: Little is known about how urea reduction ratio (URR) and hemoglobin (Hb) level relate as clinical performance measures (CPMs) in dialysis facilities. This study examined the relationship between these CPMs as a reflection of underlying processes.

Study Design: Cross-sectional observational.
