This study uses Swedish national registry data to identify triggers for violent behavior in patients with schizophrenia spectrum and bipolar disorders, and to compare risk in those populations vs healthy controls.
This survey reports on the factors that applicants to dermatology residencies consider most important when choosing a program for further training.
The direct-access online model results in equivalent improvements in atopic dermatitis clinical outcomes as in-person care. Direct-access online care may represent an innovative model of delivering dermatological services to patients with chronic skin diseases.
Safavi et al characterize hospital variation in use of noninvasive cardiac imaging and the association of imaging use with downstream testing, interventions, and outcomes. Amsterdam and Aman provide an Invited Commentary, and Redberg provides an Editor’s Note.
Fazel and coauthors examine the relationship between traumatic brain injury and premature mortality and determine the role of psychiatric comorbidity.
To determine population-based rates of the use of diagnostic imaging procedures with ionizing radiation in children, stratified by age and sex.
Retrospective cohort analysis.
All settings using imaging procedures with ionizing radiation.
Individuals younger than 18 years, alive, and continuously enrolled in UnitedHealthcare between January 1, 2005, and December 31, 2007, in 5 large US health care markets.
Number and type of diagnostic imaging procedures using ionizing radiation in children.
A total of 355 088 children were identified; 436 711 imaging procedures using ionizing radiation were performed in 150 930 patients (42.5%). The highest rates of use were in children older than 10 years, with frequent use in infants younger than 2 years as well. Plain radiography accounted for 84.7% of imaging procedures performed. Computed tomographic scans—associated with substantially higher doses of radiation—were commonly used, accounting for 11.9% of all procedures during the study period. Overall, 7.9% of children received at least 1 computed tomographic scan and 3.5% received 2 or more, with computed tomographic scans of the head being the most frequent.
Exposure to ionizing radiation from medical diagnostic imaging procedures may occur frequently among children. Efforts to optimize and ensure appropriate use of these procedures in the pediatric population should be encouraged.
