Voltage-gated sodium channels have been implicated in acute and chronic neuropathic pain. Among subtypes, Nav1.7 single mutations can cause congenital indifference to pain or chronic neuropathic pain syndromes, including paroxysmal ones. This channel is co-expressed with Nav1.8, which sustains the initial action potential; Nav1.3 is an embrionary channel(More)
The objective of this study was to review the literature on glossopharyngeal neuralgia (GN) and to discuss its differential diagnosis and treatment options. Despite the significant improvement of trigeminal neuralgia with pharmacological treatment, GN has a higher incidence of treatment failure and neurosurgery is necessary for the majority of patients.(More)
OBJECTIVE To determine the psychological aspects of orofacial pain in trigeminal neuralgia (TN) and temporomandibular disorder (TMD), and associated factors of coping as limitations in daily activities and feelings about the treatment and about the pain. METHOD 30 patients were evaluated (15 with TN and 15 with TMD) using a semi-directed interview and the(More)
Persistent pain is a frequent health problem in the elderly. Its prevalence ranges from 45% to 80%. Chronic diseases, such as depression, cardiovascular disease, cancer and osteoporosis have a higher prevalence in aged individuals and increase the risk of developing chronic pain.

The objective of the current study was to evaluate disease-related beliefs, adherence to treatment, quality of life, coping strategies and cognitive status in a group of Brazilian patients with Temporomandibular Disorder (TMD). Thirty patients were evaluated with a semi-directed interview, the Coping Strategies Inventory, and a Mini-Mental State(More)
OBJECTIVES To determine somesthetic, olfactory, gustative and salivary abnormalities in patients with burning mouth syndrome (BMS), idiopathic trigeminal neuralgia (ITN) and trigeminal postherpetic neuralgia (PHN). SUBJECTS AND METHODS Twenty patients from each group (BMS, ITN, PHN) and 60 healthy controls were evaluated with a systematized quantitative(More)
OBJECTIVE [corrected] To evaluate a sample of patients with persistent facial pain unresponsive to prior treatments. METHODS Hospital records of 26 patients with persistent facial pain were reviewed (20 female and 6 male). RESULTS Patients were classified into three groups according to their presenting symptoms: a)Group I, eight patients (30.7%) with(More)
OBJECTIVE To evaluate a sample of patients with atypical facial pain (AFP) in comparison to patients with symptomatic facial pain (SFP). METHOD 41 patients with previous diagnostic of AFP were submitted to a standardized evaluation protocol, by a multidisciplinary pain team. RESULTS 21 (51.2%) were considered AFP and 20 (48.8%) (SFP) received the(More)
The objective of this article was to investigate, with a systematic protocol of quantitative sensory testing, patients with persistent idiopathic facial pain (PIFP) and others with trigeminal traumatic neuropathic pain (TTN) compared to controls. Thirty patients with PIFP, 19 with TTN, and 30 controls were evaluated on subjective numbness and dysesthesia(More)
Fibromyalgia syndrome (FS) is a chronic painful condition with sensory, motor and affective dysfunctions. Few studies had investigated the trigeminal area, and little is known about its association with hemisensory syndrome, which is characterized by chronic pain restricted to hemibody. Our objective was to investigate sensorial abnormalities with(More)
