"Hot Tongue and Mouth" on 18F-FDG PET/CT Due to Buccolingual Masticatory Syndrome, Caused by Metoclopramide Antiemetic Treatment.
Clin Nucl Med
February 2025
From the Department of Nuclear Medicine and PET-Centre, Aarhus University Hospital, Aarhus, Denmark.
We present a case of a 66-year-old man, where 18F-FDG PET/CT revealed intense FDG uptake in the tongue, lips, cheeks, and chewing musculature and distinct activation of the somatosensory and motor cortex corresponding to the mouth and tongue. The patient suffered from buccolingual masticatory syndrome, characterized by tardive dyskinesia, meaning uncontrollable, repetitive movements of the tongue, lips, cheeks, and masticatory musculature. In this case, the buccolingual masticatory syndrome was caused by metoclopramide antiemetic treatment.

Department of Clinical Psychology, The Third Affiliated Hospital of Soochow University, Changzhou, China.
Background: Deutetrabenazine is a widely used drug for the treatment of tardive dyskinesia (TD), and post-marketing testing is important. There is a lack of real-world, large-sample safety studies of deutetrabenazine. In this study, a pharmacovigilance analysis of deutetrabenazine was performed based on the FDA Adverse Event Reporting System (FAERS) database to evaluate its relevant safety signals for clinical reference.

Positron emission tomography (PET) is frequently used to obtain target occupancy (%TO) of central nervous system (CNS) drug candidates during clinical development. Obtaining %TO with PET can be particularly powerful when the %TO associated with efficacy is known for a protein target. Using the radiotracer [F]AV-133, the relationship between plasma concentration (PK) and %TO of NBI-750142, an experimental inhibitor of the vesicular monoamine transporter type 2 (VMAT2) was obtained in both nonhuman primate (NHP) and human.

Introduction: Chorea is a motor manifestation of Huntington's disease (HD), which can lead to decreased functional independence and falls. Even though multiple classes of medications have been used to treat this symptom, only the vesicular monoamine transporter 2 (VMAT2) inhibitors tetrabenazine, deutetrabenazine, and valbenazine have been approved by the FDA for this indication.
Areas Covered: This article reviews the pharmacological properties, clinical efficacy, safety, and tolerability of valbenazine in the treatment of chorea in HD.
