Characteristics and prevalence of orofacial pain as an initial symptom of oral and oropharyngeal cancer and its impact on the patient's functionality and quality of life.

OBJECTIVE: To evaluate the prevalence and characteristics of orofacial pain in oral and oropharyngeal cancer (OOC), at diagnosis. MATERIAL AND METHODS: a) Study group (SG; n = 74) patients with cancer were divided into 2 subgroups: oral cancer (OC) and oropharyngeal cancer (OPC); b) control group (CG; n = 74) patients within dental care. STUDY DESIGN: An Orofacial Pain Assessment, verbal descriptive scale, Helkimo dysfunction index, Quality of Life questionnaire, and Karnofsky performance status (KPS) was used for evaluation. RESULTS: The mean age was 58.46 years (79.7% male) in SG, 58.61 years (20.3% male) in CG. The pain within the SG was indicated by the following: prevalence = 91.9% (21.6% in stages 0, I, or II; 70.3% in III or IV); reason for seeking care = 50.1%; main complaint = 55.4%; most important issue in the past 7 days = 74.3%; breakthrough-like pain = 64.9%; main features: chewing or swallowing as triggering factors, wake up patient, variable duration, independent of daytime, multiple descriptors, and earache. The following indexes were worse within the SG: clinical dysfunction, quality of life, and KPS. In addition, the OC subgroup reported toothache-like pain and burning; whereas the OPC subgroup reported heavy swallowing as triggering factor, throat as location, and a bilateral earache. CONCLUSION: At diagnosis, orofacial pain, including breakthrough-like pain, was prevalent in patients with OOC, and the pattern was heterogeneous. Predominantly, the pain was moderate to severe, related to stage of cancer, and already compromising the patients' quality of life and functionality.

Balloon compression vs radiofrequency for primary trigeminal neuralgia: a randomized, controlled trial.

ABSTRACT: Surgical procedures are necessary in up to 50% of trigeminal neuralgia patients. Although radiofrequency (RF) is more widely used, it is associated with high intraprocedural costs and long technical learning time. Other simpler procedures such as balloon compression (BC) require a lower training period and have significant lower costs. We evaluated the effects of BC and RF in pain control in primary trigeminal neuralgia in a randomized, double-blinded, head-to-head trial. Individuals were randomly allocated in 1 of 2 groups: BC and RF. Throughout pain, psychological and quality of life measurements were performed at baseline and after surgery. The main outcome was the worst pain in the last 24 hours (0-10) at 6 months postoperatively. After the inclusion of half of the estimated sample, a preplanned interim analysis was performed when 33 patients (62.1 ± 9.4 y.) completed the study. Pain intensity (confidence interval [CI] 95% 0.6 to 3.8, and -0.6 to 2.2, for BC and RF) did not significantly differ. Complications, interference of pain in daily life (CI 95% -0.1 to 2.3 and -0.4 to 2.3, for BC and RF), neuropathic pain symptoms (CI 95% 1.7 to 3.6 and 3.0 to 5.7, for BC and RF), mood (CI 95% 4.8 to 11.5 and 5.5 to 15.1, BC and RF, respectively), medication use, and quality of life (CI 95% 80.4 to 93.1 and 83.9 to 94.2, for BC and RF) were also not different. Radiofrequency presented more paresthetic symptoms than BC at 30 days after intervention. Based on these results, the study was halted due to futility because BC was not superior to RF.

The Orofacial Pain Clinic Questionnaire (EDOF-HC) in the evaluation and diagnosis of orofacial pain.

BACKGROUND: Diagnostic tools are necessary for the anamnesis and examination of orofacial pain, in order to fulfill diagnostic criteria and to screen potential causes of pain. OBJECTIVE: To evaluate the Orofacial Pain Clinic Questionnaire (EDOF-HC) in the assessment and diagnosis of orofacial pain. METHODS: Overall, 142 patients were evaluated and classified according to the criteria of the International Headache Society and International Association for the Study of Pain. All of them were evaluated with the EDOF-HC questionnaire, which consists of the orofacial and medical history, as well as the orofacial examination. Data were statistically analyzed with chi-square test and Bonferroni correction, one-way ANOVA with Tukey post hoc test, the two-step cluster and decision tree methods. RESULTS: There were diferences in pain descriptors, pain in maximum mouth opening, number of trigger points, and history of previous surgery between the groups, which were classified into trigeminal neuralgia, burning mouth syndrome, temporomandibular disorders and trigeminal posttraumatic neuropathic pain with classification analysis. CONCLUSIONS: The EDOF-HC is a clinical supportive tool for the assessment of orofacial pain. The instrument may be used to support data collection from anamnesis and examination of patients according to the diagnostic criteria of most common orofacial conditions. It is also useful in the investigation of local and systemic abnormalities and contributes for the diagnosis of conditions that depend on exclusion criteria.

Chronic facial pain: different comorbidities and characteristics between neuropathic and nonneuropathic conditions.

OBJECTIVE: The aim of this study was to investigate the association between comorbidities and chronic diseases and neuropathic and nonneuropathic orofacial pain diagnoses to suggest subclassifications of disease. STUDY DESIGN: This was a cross-sectional, retrospective, case-control study. We evaluated 174 patients with orofacial pain and 132 controls by using a systematic protocol that consisted of medical history and demographic, pain, and orofacial characteristics. Patients were grouped according to their diagnosis-neuropathic or non-neuropathic pain; medical comorbidities; and exclusion criteria. Analyses included Z-score normalization, χ2 test, Fisher's exact test, 1-way analysis of variance (ANOVA), Student t test, Pearson's correlation coefficient, 2-step clustering, and logistic regression at 95% confidence level. RESULTS: Functional chronic diseases were prevalent and correlated with pain and orofacial features. Three groups were identified in the cluster analysis: neuropathic facial pain, other orofacial pain syndromes, and fibromyalgia/temporomandibular disorders (TMDs). Logistic regression showed that hypothyroidism and gastritis were predictors for nonneuropathic orofacial conditions. Psychiatric diseases and gastritis were more prevalent among patients with generalized pain syndromes and TMDs and less prevalent among patients with neuropathic pain. CONCLUSIONS: Functional comorbidities were associated with orofacial and dental features and may correspond to multimorbidity states in patients with chronic orofacial pain. The findings support the hypothesis that nonneuropathic orofacial pain syndromes could be functional disorders.

Resultados: Houve diferenças entre os diagnósticos quanto aos descritores da dor, dor na abertura bucal máxima, número de pontos-gatilho mastigatórios e história prévia de cirurgia, o que esteve de acordo com a classificação nos diagnósticos de neuralgia do trigêmeo, síndrome da ardência bucal, disfunção temporomandibular e dor neuropática pós-traumática trigeminal. Conclusões: O Questionário da Equipe de Dor Orofacial (EDOF-HC) mostrou ser um instrumento de apoio para a avaliação da dor orofacial, útil na coleta de dados de anamnese e exame clínico dos pacientes, observando os principais sinais e sintomas relacionados aos critérios diagnósticos das condições orofaciais dolorosas mais comuns. Também é útil na avaliação de comorbidades locais e sistêmicas e contribui para o diagnóstico de condições que dependem em critérios de exclusão.

A new biofeedback approach for the control of masseter and temporal myalgia: Utilization of an awake posterior interocclusal device.

Objective: To evaluate the improvement in reducing the pain of patients diagnosed with masticatory myofascial pain and bruxism when undergoing treatment with a partial posterior interocclusal device for the management and control of awake bruxism through biofeedback. Methods: Sixty patients were evaluated during the following periods: pretreatment, 7, 30, and 90 days. The evaluation was carried out by measuring the reduction in pain using clinical and numerical scales. Results: The majority of the patients who complained of masticatory myofascial pain, TMJ, and neck pain experienced a significant reduction in pain between t0 and t30 (p < 0.0001). After 30 days of using the device, the improvement remained at the same level, without any recurrence of pain up to t90. Conclusion: The utilization of a posterior interocclusal device for the management and control of awake bruxism through biofeedback contributed to the reduction of pain in the majority of patients.

Increased Anxiety-Like Behavior in the Acute Phase of a Preclinical Model of Periodontal Disease.

Periodontal disease (PD) is an infectious-inflammatory oral disease that is highly prevalent among adolescence and adulthood and can lead to chronic orofacial pain and be associated with anxiety, stress and depression. This study aimed to identify anxiety-like behaviors in the ligature-induced murine preclinical model of PD in different phases of the disease (i.e., acute vs. chronic). Also, we investigated orofacial mechanical allodynia thresholds and superficial cortical plasticity along the orofacial motor cortex in both disease phases. To this aim, 25 male Wistar rats were randomly allocated in acute (14 days) or chronic (28 days) ligature-induced-PD groups and further divided into active-PD or sham-PD. Anxiety-like behavior was evaluated using the elevated plus maze, mechanical allodynia assessed using the von Frey filaments test and superficial motor cortex mapping was performed with electrical transdural stimulation. We observed increased anxiety-like behavior in active-PD animals in the acute phase, characterized by decreased number of entries into the open arm extremities [t (1,7) = 2.42, p = 0.04], and reduced time spent in the open arms [t (1,7) = 3.56, p = 0.01] and in the open arm extremities [t (1,7) = 2.75, p = 0.03]. There was also a reduction in the mechanical allodynia threshold in all active-PD animals [Acute: t (1,7) = 8.81, p < 0.001; Chronic: t (1,6) = 60.0, p < 0.001], that was positively correlated with anxiety-like behaviors in the acute group. No differences were observed in motor cortex mapping. Thus, our findings show the presence of anxiety-like behaviors in the acute phase of PD making this a suitable model to study the impact of anxiety in treatment response and treatment efficacy.

Quantitative sensory testing in elderly: longitudinal study.

OBJECTIVE: To evaluate elderly patients in a geriatric service, along with their sensory characteristics and their association with clinical aspects. METHODS: This was a descriptive longitudinal study. We enrolled 36 healthy participants of both sexes in this study. The following instruments were used and evaluations performed: clinical evaluation, Mini-Mental State Exam, and quantitative sensory testing. RESULTS: During the follow-up, there was reduction of mean corpuscular volume at each evaluation (p < 0.001) and significant increase in mean corpuscular hemoglobin concentration (p < 0.001). There was an increase of the olfactory (p < 0.001), salty (p = 0.024), sour (p = 0.020), bitter (p = 0.001), facial cold (p = 0.019), hand cold (p = 0.004), facial tactile (p < 0.001), hand tactile (p = 0.012) and facial vibration (p = 0.018) thresholds. Previous existing morbidities were associated with sensitivity changes in the individuals in this sample. CONCLUSION: This longitudinal study suggests that the loss of sensitivity with aging may be associated with the presence of morbidities in elders.

Pain and temporomandibular disorders in patients with eating disorders.

Orofacial pain and temporomandibular dysfunction may cause chronic facial pain, which may interfere with the emotional state and food intake of patients with eating disorders (ED), such as anorexia nervosa (AN) and bulimia nervosa (BN). Sixty-four patients were assigned to four groups: Group A (AN - restricting subtype): 07; Group B (AN - purging subtype ): 19; Group C (BN): 16; and Group D (control): 22. Complaints of pain are more prevalent in individuals with eating disorders (p<0.004). There are differences between the presence of myofascial pain and the number of hospitalizations (p = 0.046) and the presence of sore throat (p=0.05). There was a higher prevalence of masticatory myofascial pain and complaints of pain in other parts of the body in ED patients; however, there was no difference between ED subgroups. There was no difference in the number of self-induced vomiting between ED patients with and without myofascial pain.

Acupuncture treatment for idiopathic trigeminal neuralgia: A longitudinal case-control double blinded study.

OBJECTIVE: To evaluate the treatment effect of acupuncture on patients with idiopathic trigeminal neuralgia (ITN) by case-control longitudinal blinded study. METHODS: Sixty ITN patients and 30 healthy subjects were included. The ITN patients were randomly assigned to acupuncture group (15 cases), sham-acupuncture group (15 cases) and carbamazepine group (30 cases), respectively. Clinical orofacial evaluation (including pain intensity and medication doses), research diagnostic criteria for temporomandibular disorders (RDC/TMD) and Helkimo indexes (for functional evaluation of the masticatory system), and quantitative sensory testing for sensory thresholds (gustative, olfactory, cold, warm, touch, vibration and superficial and deep pain) were evaluated before treatment, immediately after treatment, and 6 months after treatment. RESULTS: The mean pain intensity by the Visual Analogue Scale only decreased in the acupuncture group at the last evaluation (P=0.012). Patients in the sham-acupuncture group had an increase in carbamazepine doses according to the prescriptions (P<0.01). There was a reduction in secondary myofascial pain and mandibular limitations at the acupuncture and sham-acupuncture groups, however only the acupuncture group kept the changes after 6 months (P<0.01, P=0.023). There was a decrease in mechanical thresholds in the acupuncture group (tactile, P<0.01; vibration, P=0.027) and an increase in deep pain thresholds in both acupuncture and sham-acupuncture groups (P=0.013). CONCLUSIONS: Acupuncture can be an option in the treatment of ITN due to its analgesic effect in both ITN and secondary myofascial pain associated with it.

Post-operative orofacial pain, temporomandibular dysfunction and trigeminal sensitivity after recent pterional craniotomy: preliminary study.

BACKGROUND: Surgical trauma at the temporalis muscle is a potential cause of post-craniotomy headache and temporomandibular disorders (TMD). The aim of this study was to evaluate the prevalence of pain, masticatory dysfunction and trigeminal somatosensory abnormalities in patients who acquired aneurysms following pterional craniotomy. METHODS: Fifteen patients were evaluated before and after the surgical procedure by a trained dentist. The evaluation consisted of the (1) research diagnostic criteria for TMD, (2) a standardized orofacial pain questionnaire and (3) a systematic protocol for quantitative sensory testing (QST) for the trigeminal nerve. RESULTS: After pterional craniotomy, 80% of the subjects, 12 patients, developed orofacial pain triggered by mandibular function. The pain intensity was measured by using the visual analog scale (VAS), and the mean pain intensity was 3.7. The prevalence of masticatory dysfunction was 86.7%, and there was a significant reduction of the maximum mouth opening. The sensory evaluation showed tactile and thermal hypoesthesia in the area of pterional access in all patients. CONCLUSIONS: There was a high frequency of temporomandibular dysfunction, postoperative orofacial pain and trigeminal sensory abnormalities. These findings can help to understand several abnormalities that can contribute to postoperative headache or orofacial pain complaints after pterional surgeries.

Clinical evidence on visceral pain. Systematic review / Evidência clínica sobre dor visceral. Revisão sistemática

ABSTRACT BACKGROUND AND OBJECTIVES: Visceral pain is induced by abnormalities of organs such as stomach, kidneys, bladder, gallbladder, intestines and others and includes distension, ischemia, inflammation and mesenteric traction. It is responsible for physical and psychic incapacity, absenteeism and poor quality of life. This study aimed at discussing major aspects of visceral pain with regard to prevalence, etiology and diagnosis. CONTENTS: According to Evidence-Based Medicine concepts, visceral pain etiology, diagnosis and prognosis were reviewed in LILACS, EMBASE and Pubmed databases. Therapeutic studies were not selected. The following terms were used as search strategy: ("visceral pain"[MeSH Terms] OR ("visceral"[All Fields] AND "pain"[All Fields]) OR "visceral pain"[All Fields]). Only studies published in Portuguese, English or Spanish were included. Narrative reviews with opinionated content and specific therapeutic procedures of medical specialties were excluded. Studies on visceral pain related to heart, cancer and musculoskeletal diseases and pregnancy were also excluded. CONCLUSION: Visceral pain is a heterogeneous condition where most frequent presentation is abdominal pain in the course of irritable bowel syndrome. Other diseases induce visceral pain and adequate diagnosis is critical for effective treatment.

Outras doenças cursam com dor visceral e o diagnóstico adequado é fundamental para o tratamento eficaz.

Effects of localized versus widespread TMD pain on sleep parameters in patients with bruxism: A single-night polysomnographic study.

OBJECTIVE: The purpose of this study was to investigate whether the presence of concomitant widespread pain could influence the polysomnographic characteristics of patients with Sleep Bruxism(SB) and chronic masticatory muscle pain(TMD). METHODS: 20 SB/TMD patients (17 women and 3 men) were evaluated according to the RDC/TMD questionnaire; and were divided into two groups according to the absence (Group A) or presence (Group B) of widespread pain. They were evaluated in a one night polysomnography paradigm. RESULTS: Group B had lower sleep efficiency (p=0.034) and higher mean age (p=0.000) than Group A. Self-reported orofacial pain complaints, clinical and emotional aspects (RDC/TMD Axis I and II), and SB PSG parameters were similar in both groups; all patients had masticatory myofascial pain and the pain characteristics were bilateral location (95.0%) and tightness/pressure quality (70.0%). CONCLUSIONS: At a single-night PSG, SB/TMD patients with widespread pain presented lower PSG sleep efficiency and higher mean age.

Could pain understanding by patients help the assessment of trigeminal neuralgia? / A compreensão da dor pelo paciente pode ajudar no tratamento da neuralgia do trigêmeo?

ABSTRACT BACKGROUND AND OBJECTIVES: To observe the efficacy of pain management by means of an educational proposal to address patients with trigeminal neuralgia, which is a chronic pain with high daily activity limitation rates. METHODS: Eight patients being treated of trigeminal neuralgia participated in weekly meetings on pain in a general reference hospital. Patients had uncontrollable pain in spite of treatments so they would come very frequently to the hospital (once every one or two weeks). Patients were invited to participate in a series of meetings (four) to receive information and discuss about the disease and pain. RESULTS: There has been increased interval between appointments for two patients, who went from weekly to biannual visits, and six patients were discharged with controlled symptoms. CONCLUSION: Education on pain has helped its management and coping by patients, by means of understanding their condition, in addition to improving their abilities to deal with it, decreasing hospital visits due to less pain recurrence.

RESUMO JUSTIFICATIVA E OBJETIVOS: Verificar a eficácia do tratamento da dor, por meio de uma proposta educativa para a abordagem de pacientes com neuralgia do trigêmeo, uma dor crônica com alto índice de limitações em atividades diárias. MÉTODOS: Oito pacientes com neuralgia do trigêmeo em tratamento frequentaram encontros semanais sobre a dor em um hospital geral de referência. Eles apresentavam dor incontrolável apesar dos tratamentos e por isso compareciam em atendimentos com alta frequência (1 vez a cada 1 ou 2 semanas). Eles foram convidados a participar de uma série de encontros (4) para receber informações e discutir sobre a doença e a dor. RESULTADOS: Observou-se que houve um aumento nos intervalos de tempo entre as consultas de 2 pacientes, que passaram de visitas semanais para bienais, e 6 pacientes tiveram alta e controle dos sintomas. CONCLUSÃO: Educação em dor auxiliou no seu manuseio pelos pacientes e em seu enfrentamento, por meio do entendimento de sua condição e no aumento de habilidades para lidar com ela, reduzindo visitas ao ambulatório por conta da menor recorrência de dor.

Temporomandibular disorders in fibromyalgia patients: are there different pain onset?

OBJECTIVE: To identify temporomandibular disorders (TMD) symptoms in two groups of fibromyalgia patients according to the temporal relation between the onset of facial pain (FP) and generalized body pain (GBP). CROSS-SECTIONAL STUDY DESIGN: Fifty-three consecutive women with fibromyalgia and FP were stratified according to the onset of orofacial pain: Group-A (mean age 47.30 ± 14.20 years old), onset of FP preceded GBP; Group-B (mean age 51.33 ± 11.03 years old), the FP started concomitant or after GBP. CLINICAL ASSESSMENT: Research Diagnostic Criteria for Temporomandibular Disorders and the Visual Analogue Scale. RESULTS: Myofascial pain with mouth opening limitation (p = 0.038); right disc displacement with reduction (p = 0.012) and jaw stiffness (p = 0.004) were predominant in Group A. Myofascial pain without mouth opening limitation (p = 0.038) and numbness/burning were more common in Group B. CONCLUSION: All patients had temporomandibular joint symptoms, mainly muscle disorders. The prevalence of myofascial pain with limited mouth opening and right TMJ disc displacement with reduction were higher in Group A.

Oral Infections and Cytokine Levels in Patients with Alzheimer's Disease and Mild Cognitive Impairment Compared with Controls.

BACKGROUND: Oral infections are prevalent in the adult population. Their impact includes the implication as a risk factor for Alzheimer's disease (AD), altering its progression. One of the potential mechanisms involves immune mediators such as circulating cytokines. OBJECTIVE: The goal of the present study was to investigate the prevalence of oral infections and blood levels of IL-1ß, TNF-α, and IL-6 in patients with AD, mild cognitive impairment (MCI), and controls. METHODS: Sixty-five elderly were evaluated (25 AD, 19 MCI, and 21 controls) by the following methods: Mini Mental State Exam, Questionnaire of Functional Activities, periodontal and oral evaluation, and blood concentrations of IL-1ß, TNF-α and IL-6. RESULTS: Patients with AD had high serum IL-6 levels (p = 0.029), and patients with periodontitis had high serum TNF-α levels (p = 0.005). There was an association between IL-6 and TNF-α in patients with AD/MCI and periodontitis (p = 0.023). CONCLUSION: The increased levels of TNF-α and IL-6 in this study suggests their implication in the overlapping mechanisms between oral infections and AD. Longitudinal studies are necessary for further investigation.
