Imaging helps remove 3-cm toy from aerodigestive tract of old dementia patient
Florida: A recent case report published in the Cureus Journal of Medical Science, presents the case of a 83-year old woman in Florida in which imaging helped physicians identify and remove a spinning top toy. The woman had end-stage dementia and an oral fixation.
Initially the object, which was 3 cm in diameter was missed by junior radiology resident, on the patient's chest radiographs and chest and brain CT images. Following three day admission of the patient, a new team analysed the scans again and identified an object in the woman's hypopharynx. The case highlights the challenges of diagnosing and extracting foreign objects in patients with dementia.
"This case provides an opportunity to discuss the unique challenges of performing anesthesia on patients undergoing the extraction of a large upper aerodigestive tract foreign body, complicated by end-stage dementia," wrote Dharam Persaud-Sharma, University of Florida, Gainesville, and colleagues.
Frontotemporal lobar dementia (FTLD) is an umbrella term that includes several disorders that result in marked deterioration of cognitive and social behaviors. Specifically, patients with FTLD develop hyperorality which can lead to binge-eating, as well as the ingestion of inedible objects.
People diagnosed with frontotemporal lobar dementia experience a marked decline in cognitive and social behaviors and often develop hyperorality. In addition to excessive chewing, sucking, or eating, they often eat items other than food. Once patients enter the later stages of dementia, many become nonverbal, making hyperorality a greater risk because they are unable to explain what they swallowed or that an object is stuck. As dementia progresses, patients may also have difficulty swallowing.
These factors should be considered for patients who experience changes in eating habits or upper airway distress, according to the authors. Physicians must rely on thorough reviews of imaging results to diagnose and treat. Foreign objects may be removed from the oropharynx and oral and nasal cavities without anesthesia; however, sedation is often more appropriate in patients with dementia who have trouble cooperating or following directions.
Case Presentation
An 83-year-old woman with advanced frontal lobe dementia, hypertension, and dyslipidemia presented to the emergency department from home due to increased somnolence reported by the patient's daughter. Her decreased responsiveness and general malaise led her to be admitted for further evaluation. She was nonverbal and her appetite had decreased, and the patient's daughter said her mother had a productive cough with increased shortness of breath. She remained in a lethargic state and didn't respond to verbal commands. The woman had previously been diagnosed with advanced frontal lobe dementia, hypertension, and high cholesterol.
The patient's vital signs were normal. Lab tests showed she had low potassium levels, as well as platelet and red and white blood cell counts. A chest CT showed an incidental 1.6-cm nodular lesion in the woman's thoracic wall and several nodules in the thyroid. Saliva tests showed infection with the bacteria Mycoplasma pneumonia, which causes coughing and a sore throat. She was treated with antibiotics and an inhaled steroid, according to the authors.
Three days after she was admitted to the hospital, a new medical team took over and noticed the woman had noisy breathing, which occurs with obstructed air flow. The team reexamined the previously obtained chest x-ray and brain and chest CT scans. The images revealed a large foreign body in the woman's hypopharynx-upper esophagus. The object was not described in the report initially read by junior radiology residents.
The patient failed a swallow study, and images were acquired of her neck soft tissue and anterior-posterior cervical spine, which revealed a 5.4 x 2.3 x 4.3-cm foreign body lodged in her hypopharynx anterior to the C3-C6 vertebrae, the authors wrote.
The woman was placed under general anesthesia to avoid erratic movements that could result in puncturing her esophagus. An otorhinolaryngologist surgeon used direct laryngoscopy and angled forceps for the extraction. Rapid sequence induction without application of cricoid pressure was used due to the position of the object, which was a spinning top toy, they wrote.
After the operation, the patient was more awake and active and her appetite returned; however, her neuropathological oral-fixation behaviors increased dramatically, the authors noted.
Patients with dementia who ingest foreign objects pose unique challenges for clinicians.
"Different methods of object retrieval vary widely and ultimately the characteristics of the aspirated object, the degree of obstruction and the patient's ability to protect their airway should be considered when choosing the best approach for patients with dementia," they wrote.
The case report titled, "Large Aerodigestive Tract Foreign Body Extraction Complicated by End-Stage Dementia," is published in the Cureus Journal of Medical Science.
