1. Injuries in children from ingesting button batteries are
increasing
2. The type and size of the ingested battery influence the
likelihood of complications
3. Urgency of management depends on the location of the battery
4. Honey or sucralfate should be administered after battery
ingestion
5. Children should be monitored for long-term complications
EVIDENCE-BASED ANSWER:
NOT VERY WELL. IN ASYMPTOMATIC PATIENTS, CAROTID ARTERY CALCIFICATION SEEN ON RADIOGRAPH HAS A POSITIVE PREDICTIVE VALUE OF 70% AND A NEGATIVE PREDICTIVE VALUE OF 75% FOR CAROTID ARTERY STENOSIS (STRENGTH OF RECOMMENDATION [SOR]: B, SYSTEMATIC REVIEW OF OBSERVATIONAL STUDIES WITH HETEROGENEOUS RESULTS AND A RETROSPECTIVE COHORT STUDY). CAROTID CALCIFICATIONS ON RADIOGRAPHS MAY BE MORE PREDICTIVE OF CAROTID STENOSIS IN PEOPLE WITH ATHEROSCLEROTIC RISK FACTORS (SOR: C, CROSS-SECTIONAL STUDY). HARMS OUTWEIGH BENEFITS IN SCREENING FOR CAROTID ARTERY STENOSIS IN ASYMPTOMATIC ADULTS (SOR: B, MULTIPLE COHORT STUDIES); THEREFORE, INCIDENTAL RADIOGRAPHIC CAROTID ARTERY CALCIFICATIONS IN ASYMPTOMATIC PATIENTS SHOULD NOT PROMPT FURTHER TESTING.
Importance: Carotid artery stenosis is atherosclerotic disease that affects extracranial carotid arteries. Asymptomatic carotid artery stenosis refers to stenosis in persons without a history of ischemic stroke, transient ischemic attack, or other neurologic symptoms referable to the carotid arteries. The prevalence of asymptomatic carotid artery stenosis is low in the general population but increases with age.
Objective: To determine if its 2014 recommendation should be reaffirmed, the US Preventive Services Task Force (USPSTF) commissioned a reaffirmation evidence review. The reaffirmation update focused on the targeted key questions on the potential benefits and harms of screening and interventions, including revascularization procedures designed to improve carotid artery blood flow, in persons with asymptomatic carotid artery stenosis.
Population: This recommendation statement applies to adults without a history of transient ischemic attack, stroke, or other neurologic signs or symptoms referable to the carotid arteries.
Evidence assessment: The USPSTF found no new substantial evidence that could change its recommendation and therefore concludes with moderate certainty that the harms of screening for asymptomatic carotid artery stenosis outweigh the benefits.
Recommendation: The USPSTF recommends against screening for asymptomatic carotid artery stenosis in the general adult population. (
