This study aimed to investigate the prevalence of clinical features of temporomandibular disorders (TMD) in patients with fibromyalgia. The test group (FMG) consisted of 40 women with fibromyalgia (FM) compared to the control group of 40 healthy subjects using the research diagnostic criteria for temporomandibular disorders (RDC/TMD). The variables were compared using Fisher's exact test and a Mann-Whitney test. Facial pain was reported by 85% of the FM group, and 77.5% were diagnosed with myofascial TMD. Muscle pain during jaw movements, daytime bruxism/clenching, and limited mouth opening were significantly higher in the test group. There was no difference between groups in: (1) joint noises; (2) sleep bruxism/clenching; and (3) excursive or non-excursive movements. Classic signs of TMD, such as joint noise and self-reporting of clenching at night, are not associated with fibromyalgia syndrome as demonstrated in the current study. However, the self-reported daytime parafunctions, muscle pain in jaw movements, and limited mouth opening are features of the patients in the current study. This study revealed specific muscle involvement of TMD is also presence in FM.
O tratamento de úlceras cutâneas por estimulação elétrica tem crescido na prática clínica, no entanto, faltam estudos que investiguem a efetividade desse recurso em acompanhamento prolongado ou até que ocorra a cicatrização completa das lesões. Assim, a estimulação elétrica de alta voltagem (EEAV) foi aplicada em úlceras cutâneas crônicas com o objetivo de reduzir a área da lesão. Para tanto, participaram do estudo quatro homens que apresentavam seis úlceras cutâneas que receberam a EEAV (fase=15ms; F=100 Hz; T: 100 a 150 V; fases gêmeas), 2 vezes por semana, durante 30 minutos. O eletrodo com polaridade negativa foi colocado sobre a lesão e o positivo no trajeto vascular. As úlceras foram avaliadas pré e pós-intervenção por meio da fotogrametria, sendo calculada a área da lesão. Como resultado, observamos o fechamento completo da lesão nos sujeitos I e II (área de 4,66 cm² para 0 após 21 sessões e de 1,74 cm² para 0 após 16 sessões, respectivamente). O sujeito III obteve redução de 93% na área da lesão direita (de 2,02 para 0,14 cm²) e na esquerda de 80,40% (de 2,50 para 0,49 cm²), após 100 sessões. No sujeito IV ocorreu o fechamento completo da lesão sacral (de 10,74 cm² para 0) e a redução da lesão isquiática de 11,01 para 2,43 cm², após 75 sessões. Desse modo, concluímos que a EEAV facilitou o processo de cicatrização das úlceras estimuladas, pois as áreas de todas as úlceras apresentaram diminuição superior a 78%, havendo cicatrização completa em três delas.
Facial pain often persists long after any identifiable organic pathology has healed. Moreover, in a subgroup of patients with temporomandibular disorder (TMD), no treatment is effective. Knowledge of factors associated with persistent pain in TMD could help identify personalized treatment approaches. Therefore, we conducted a critical review of the literature for the period from January 2000 to December 2013 to identify factors related to TMD development and persistence. The literature findings showed that chronic TMD is marked by psychological distress (somatization and depression, affective distress, fear of pain, fear of movement, and catastrophizing) and characteristics of pain amplification (hyperalgesia and allodynia). Furthermore, these factors seem to interact in TMD development. In addition, our review demonstrates that upregulation of the serotonergic pathway, sleep problems, and gene polymorphisms influence the chronicity of TMD. We conclude that psychological distress and pain amplification contribute to chronic TMD development, and that interactions among these factors complicate pain management. These findings emphasize the importance of multidisciplinary assistance in TMD treatment.
Aim: To compare temporomandibular (TMD) subgroups classified according to the presence of localized pain (LP) or widespread pain (WP) in order to assess the quality of life domains and verify which components affect most the functional capacity of facial pain patients. Methods: A cross-sectional study was conducted and the Short Form-36 Health Survey was applied in order to assess quality of life. Thirty-nine TMD/WP patients, 37 TMD/LP patients and 40 subjects free of TMD complaints were evaluated. Results: TMD/WP patients differed significantly from healthy controls in all SF-36 components and TMD/LP patients ranked between them. It was also observed that patients with bodily pain and TMD with WP are respectively, 4.16 and 49.42 times more likely to have low functional capacity. Conclusions: Functional capacity in TMD subgroups was only affected by the presence of bodily pain and WP. These patients feature high chance of low functional capacity. Furthermore, TMD patients with localized and widespread pain share roleemotional impairments.
