Botulinum toxin (BoNT) has been widely employed to treat poststroke spasticity, cervical dystonia and muscle hyperactivity. Recently, BoNT injections are increasingly used in treating musculoskeletal pain. The mechanism of BoNT in pain relief comprises relaxation of overused muscles and inhibition of inflammatory nociceptive cytokines/neurotransmitters. As BoNT injections seem promising in treating painful musculoskeletal disorders, we aimed to investigate its effectiveness in shoulder and upper limb pain. Although the present article is a narrative review, we employed a systematic approach to search for relevant articles in PubMed. A total of 19 clinical studies were included. Here, we observed that intramuscular BoNT injections were helpful in stroke patients with hemiplegic shoulder pain. In shoulder joint pain, intra-articular and intrabursal BoNT injections achieved a longer period of pain relief than corticosteroid injections. Similarly, a more durable effect of intramuscular BoNT than saline injections was seen in shoulder myofascial pain. Its use in complex regional pain syndrome and persistent upper limb pain in breast cancer survivors was insufficient, necessitating more studies. Since not all of the included studies could provide Class I of evidence based on the efficacy criteria used by American Academy of Neurology, controlled clinical trials in a larger number of patients are necessary to verify validity of these findings in the future.

Adjuvant systemic treatments in breast cancer are indicated to reduce the risk of relapse. Their systemic side effects have been well documented and include menopausal symptoms such as impaired libido and vaginal dryness, increased risk of endometrial cancer, stroke, musculoskeletal symptoms including arthralgia and myalgia, osteopenia and fractures, skin rashes, and hypercholesterolemia. However, few articles have focused on the oral mucosal reactions related to adjuvant endocrine therapies (AETs) which clearly differ from those reported with chemotherapies or other targeted therapies used for breast cancer. AETs primarily expose patient to a higher risk of worsened periodontal health, salivary flow modifications, taste disturbance, and global deterioration of oral health-related quality of life. Although the rate of permanent discontinuation of AETs because of oral mucosal changes remains low, an interdisciplinary approach to evaluate oral health and to optimize oral supportive care appears essential to ensure an appropriate management and limit dose adjustment in treated patients. In this respect and based on our clinical experience, we propose recommendations to allow oncologists, nurses, and attending practitioners to implement appropriate measures rapidly and/or refer patients to dentists.

The treatment of a complex temporomandibular disorder (TMD), such as disc displacement with reduction (DDR) associated with arthralgia and myalgia, may depends on understanding the impairments in muscle function. The aim of this study was to investigate the behavior of the anterior temporalis, masseter and sternocleidomastoid muscles in the time and frequency domains during chewing in patients with chronic painful TMD-DDR using electromyographic (EMG) analysis. Thirty-three patients who met the diagnostic criteria for TMD and 32 volunteers without TMD (control group) underwent clinical examination, chewing pattern classification and EMG analysis. For the EMG analyses, the side of habitual unilateral chewing, as determined by the chewing pattern classification, was selected for recording; in cases of bilateral chewing, the recording side was randomly selected. The EMG-EMG coherence function and EMG-EMG transfer function (gain and phase) values were obtained at the first chewing frequency peak, and the working-side masseter signal was used as a reference in the analyses of the other muscles. Compared to the control group, the TMD group showed a longer chewing stroke duration (P= 0.01) as well as changes in the coactivation and coordination strategies of the jaw muscles, evidenced by greater relative energy expenditure (P< 0.01) and impaired differential recruitment (P< 0.05) and coherence (P< 0.01). Delays in peak and temporal asynchrony occurred in the jaw and neck muscles (P< 0.05). Patients with chronic painful TMD-DDR during chewing presented changes in the jaw and neck muscles, with more compromised function of the former, which are specific to chewing.
