RESUMO
There are patients who suffer from persistent dentoalveolar pain disorder (PDAP) which is a pain of the teeth, either dentoalveolar pain or nonodontogenic toothache, and its cause has not yet been identified. An effective intervention for PDAP has not yet been established. Interventions for patients with PDAP are generally pharmacological treatments such as antidepressants, anticonvulsants, and pregabalin. However, these medicines are not always effective for patients. The pain disorder in the orofacial region including temporomandibular disorder (TMD) and PDAP was effectively treated with our original exercise therapy. However, we did observe some intractable cases of PDAP even when our original exercise therapy was used. This paper presents our findings in which Kamishoyosan improved the pain intensity in 14 out of 15 PDAP patients refractory to our original exercise therapy.
RESUMO
OBJECTIVE: The aim of this study was to elucidate the neural pathway for sound-evoked myogenic potentials (SEMPs) in monkeys with characteristics similar to those of vestibular evoked myogenic potentials in humans. METHODS: Six macaque monkeys were examined. The effects of total and selective vestibular nerve section on the SEMPs were evaluated in three monkeys. RESULTS: After total vestibular nerve section, the SEMPs and caloric nystagmus were eliminated, and the auditory brainstem response remained. After selective superior vestibular nerve section, the SEMPs remained, but caloric nystagmus was eliminated. CONCLUSIONS: The inferior vestibular nerve comprises a neural pathway for SEMPs in monkeys. SIGNIFICANCE: SEMP in monkeys may provide a model of human VEMPs.
