Origins of and solutions for neonatal medication-dispensing errors.

Purpose: Five cases of sound-alike, look-alike, neonatal medication-dispensing errors and their resolution are reviewed.

Summary: In 2008, there were five cases in which look-alike or sound-alike neonatal medication-dispensing errors occurred at our institution. A mix-up between neonatal and adult or pediatric products occurred in four of the five cases.

A longitudinal study of physical activity and body mass index among persons with unexplained chronic fatigue.

Objective And Methods: A cohort of 100 patients with unexplained chronic fatigue (CF) was assessed longitudinally for 1.5 years to determine if physical activity (kcal expended), exercise capacity (VO(2)max), perceived exertion, and body mass index (BMI) changed over time and were associated with changes in CF-related clinical status.

Results: BMI increased significantly over time but did not predict changes in clinical status.

Prospective study of the prognosis of unexplained chronic fatigue in a clinic-based cohort.

Objectives: To determine prospective changes in clinical status related to chronic fatigue over an 18-month period, and to test demographic and clinical predictors of outcome.

Methods: A cohort of 100 patients with unexplained chronic fatigue (UCF), which encompasses both chronic fatigue syndrome (CFS) and idiopathic chronic fatigue (ICF), completed questionnaire measures and medical and psychiatric evaluations on four occasions, each six months apart.

Results: Approximately 21% of the sample did not meet criteria for either CFS or ICF at their last research appointment 1.

Single-photon emission computerized tomography and neurocognitive function in patients with chronic fatigue syndrome.

Objective: The purposes of this study were to compare functional imaging under control and experimental conditions among patients with chronic fatigue syndrome (CFS) and healthy persons and to examine perceived and objective performance on a test of attention and working memory previously found to be difficult for persons with CFS.

Methods: Single-photon emission computerized tomography scans were completed on 15 subjects with CFS and 15 healthy persons twice: at rest and when performing the Paced Auditory Serial Addition Test (PASAT).

Results: No group differences were found for performance on the PASAT despite CFS subjects' perceptions of exerting more mental effort to perform the task than healthy subjects.
