Post-Surgery Musical Hallucinations of a Patriotic Canadian Song
Notice bibliographique
Résumé
A 79-year-old, right-handed, widowed female with bilateral sensorineural hearing loss of a few years' duration, presented to a peripheral hospital with a fall.The fall resulted in a subcapital fracture of the right hip without head injury.She underwent a cannulated screw fixation of the right hip and was discharged to a rehabilitation facility a few days thereafter.She began to experience neck pain and progressive motor weakness of her upper and lower extremities, with sensory deficits in the upper extremities bilaterally.After a few weeks, she could only mobilize with a wheelchair.Bowel and bladder function remained intact.A magnetic resonance image confirmed a 2.4 cm x 1.9 cm dural based mass seen anteriorly at the foramen magnum, causing cervicomedullary junction cord compression.She underwent an uneventful resection of the mass with a C1-C2 laminectomy (Figure).The mass was determined pathologically to be a meningioma.Postoperatively, she reported hearing "The Maple Leaf Forever", a Canadian patriotic song, amongst some Elvis Presley favourites, though clearly had insight that these were hallucinations.In fact, the musical hallucinations began a few days following her hip repair, but she had not brought this to medical attention fearing she would be labeled as 'crazy'.The phenomenon was bilateral.There was no tinnitus.She denied any illusions, delusions, and additional perceptual disturbances.She also had a history of depression, though stable with psychotherapy and an antidepressant.She denied any alcohol or illicit drug use.She had bilateral sensorineural hearing loss and had not worn her hearing aids since the hip surgery fearing they would be misplaced in hospital.Prior to her recent fall, she was independent for all her activities of daily living and independent activities of daily living, except for using a walker to ambulate.She was widowed, lived alone, and had two supportive daughters.She was not experiencing low mood, but had vegetative symptoms of depression including weight loss (nine pounds since her hip surgery), fatigue, and insomnia.While dismayed at her lack of progress with physiotherapy, she remained motivated.She was on dexamethasone as part of neurosurgical management for the meningioma.Her other medications were citalopram, amlodipine, dalteparin, alendronate, vitamin D and calcium.Her affect was flat, but she was alert and attentive.She had sensorineural hearing loss bilaterally.She could sing the song "The Maple Leaf Forever" and return to a different verse when interrupted.Cognitive testing included a Mini Mental State Examination score of 29/30, losing a point for visuospatial construction.Other than 4/5 power in the upper extremities,

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.

Scores machine (provisoires)
Les deux têtes enseignantes du modèle étudiant, lues sur ce travail. Un score ordonne la base pour la relecture; il n'affirme jamais une catégorie, et le statut de validation accompagne chaque rangée tel quel.
Scores de référence d'un modèle non mature (critères de maturité non atteints, 7 itérations). Un score ordonne; il n'affirme jamais une catégorie.
