Analysis of 4-fluoroamphetamine in cerumen after controlled oral application

Drug Testing and Analysis, 2020
Cerumen was found to be a promising alternative specimen for the detection of drugs. In a pilot study, drugs of abuse were identified at a higher detection rate and a longer detection window in cerumen than in urine.

Association between oral feeding versus enteral feeding and cerumen impaction in older hospitalized adults: A retrospective cohort study.

JPEN - Journal of Parenteral and Enteral Nutrition
BACKGROUND Chewing involves jaw movements that propel cerumen along the ear canal. This mechanism may be reduced in dysphagia, especially for older individuals who are enterally fed.

Malassezia japonica isolated from the cerumen of Cercopithecidae and Hylobatidae.

Medical Mycology
Species diversity of Malassezia in the cerumen of nonhuman primates (NHPs) belonging to the Cercopithecidae and Hylobatidae families was investigated. Isolates from cerumen samples collected from carcasses were identified at the species level using 26S ...
