Purpose: to analyze the association between the classification of clinical diagnoses classification (myofascial pain, disc and joint disorder) and the chronic pain graduation, depression and nonspecific physical symptoms in subjects with temporomandibular disorder.

Modelo do estudo: Caso-controle. Objetivos do estudo: Comparar a capacidade funcional, parâmetros respiratórios e qualidade de vida entre sujeitos saudáveis e pacientes com apneia obstrutiva do sono. Metodologia: Em 19 pacientes com apneia obstrutiva do sono e 19 sujeitos saudáveis foram avaliadas a qualidade de vida (The Medical Study 36-item Short-Form Health Survey), capacidade funcional (teste de caminhada de seis minutos), função pulmonar (espirometria) e força muscular respiratória (manovacuometria). Resultados: Os pacientes apresentaram declínio na qualidade de vida pelos domínios capacidade funcional, estado geral de saúde e saúde mental. A distância percorrida no teste de caminhada de seis minutos foi menor nos pacientes com apneia obstrutiva do sono. Os parâ- metros respiratórios não diferiram entre os grupos. Conclusão: Pacientes com apneia obstrutiva do sono apresentam comprometimento da qualidade de vida e da capacidade funcional

Introduction  Obstructive Sleep Apnea (OSA) is characterized by repeated episodes of upper airway obstruction during sleep.Objective  The objective of this study is to verify the craniofacial characteristics and craniocervical posture of OSA and healthy subjects, determining possible relationships with the apnea/hypopnea index (AHI).Methods  This case-control study evaluated 21 subjects with OSA, who comprised the OSA group (OSAG), and 21 healthy subjects, who constituted the control group (CG). Cephalometry analyzed head posture measurements, craniofacial measurements, and air space. Head posture was also assessed by means of photogrammetry.Results  The groups were homogeneous regarding gender (12 men and 9 women in each group), age (OSAG = 41.86 ± 11.26 years; GC = 41.19 ± 11.20 years), and body mass index (OSAG = 25.65 ± 2.46 kg/m2; CG = 24.72 ± 3.01 kg/m2). We found significant differences between the groups, with lower average pharyngeal space and greater distance between the hyoid bone and the mandibular plane in OSAG, when compared with CG. A positive correlation was found between higher head hyperextension and head anteriorization, with greater severity of OSA as assessed by AHI.Conclusion  OSAG subjects showed changes in craniofacial morphology, with lower average pharyngeal space and greater distance from the hyoid bone to the mandibular plane, as compared with healthy subjects. Moreover, in OSA subjects, the greater the severity of OSA, the greater the head hyperextension and anteriorization.

Purpose: to investigate the presence of Temporomandibular Disorder, headache and neck pain and muscle pain threshold of cervical muscles in nursing professionals exposed to occupational stress. Methods: 43 women were evaluated for the presence and severity of Temporomandibular Disorder using the Diagnostic Criteria for Temporomandibular Disorder instrument and Temporomandibular Dysfunction Index, respectively. Furthermore, they were evaluated for the pain threshold to pressure on the cervical muscles by algometry and for the presence of headache and neck pain.

Introduction: The appearance and evolution of some clinical pain conditions may be influenced by stress and other psychosocial factors. Face, head and cervical muscles may increase their activity and tension in the presence of stress, leading to craniocervicomandibular pain in individuals exposed to stress. Objective: To assess the relationship among perceived stress, anxiety, depression and craniocervicomandibular pain in nursing professionals under stress at work. Materials and Methods: Forty-three women under stress at work, according to the Job Stress Scale (JSS), were assessed by the Perceived Stress Scale (PSS), the Hospital Anxiety and Depression Scale (HADS), pressure pain threshold, measured by algometry, and muscle sensitivity to hand palpation of the masticatory and cervical muscles. Results: A low moderate level of perceived stress was found in 62.79% of the sample, anxiety in 11.63% and depression in 9.30%. The psychosocial scales correlated with each other. No correlation was found between pressure pain threshold and perceived stress, anxiety and depression. The level of pain to hand palpation correlated with the perceived stress scores. Conclusion: Pressure pain threshold was not influenced by the psychosocial factors assessed. Pain intensity to hand palpation, however, was higher as the perception of stress increased.
