Pain control after deep brain stimulation (DBS) in Parkinson's disease (PD) remains unclear. Following six months, subthalamic (STN)-DBS reduced sensory complaints related to parkinsonism and bodily discomfort, increasing central beta-endorphin level. Pallidal GPi-DBS decreased bodily discomfort and beta-endorphin levels. Unexplained pain by other conditions and bodily discomfort were negatively correlated with beta-endorphin levels. Thus, DBS regulates central opioids, and prioritizing STN is important for PD patients with significant sensory complications.

Introduction: Monoamine oxidase-B (MAO-B) inhibitors, as an add-on therapy to levodopa, are widely used in Parkinson's disease (PD). The effects of MAO-B inhibitors on quality of life remain unclear, and the aim of this systematic review and meta-analysis was to assess the efficacy and safety of MAO-B inhibitors on quality of life in different domains.

Methods: We searched PubMed, Embass, and Cochrane Library databases for randomized controlled trials of PD patients who were administered MAO-B inhibitors.

Recent data have shown a continued rise in the worldwide annual incidence and mortality rates of head and neck cancers. The present standard for diagnosis and monitoring for disease recurrence or progression involves clinical examination, imaging, and invasive biopsy techniques of lesions suspected of being malignant. In addition to limitations relating to cost, time, and patient discomfort, these methodologies have inherent inaccuracies for detecting recurrence.
