Use of Music and Voice Stimulus on Patients With Disorders of Consciousness

The objectives of this study were to check music and voice message influence on vital signs and facial expressions of patients with disorders of consciousness and to connect the existence of patient`s responses with the Glasgow Coma Scale or with the Ramsay Sedation Scale. The method was a single-blinded randomized controlled clinical trial with 30 patients, from two intensive care units, being divided into two groups (control and experimental). Their relatives recorded a voice message and chose a song according to the patient`s preference. The patients were submitted to three sessions for three consecutive days. Significant statistical alterations of the vital signs were noted during the message playback (oxygen saturation-Day 1 and Day 3; respiratory frequency-Day 3) and with facial expression, on Day 1, during both music and message. The conclusion was that the voice message was a stronger stimulus than the music.

Symptoms of Temporomandibular Disorders in the Population: An Epidemiological Study

Aims: To estimate the prevalence of symptoms of temporomandibular disorders (TMD) as a function of age and gender, in a representative urban sample from the Brazilian population. Methods: A total of 1,230 inhabitants (51.5% women) aged 15 to 65 years were interviewed by a validated phone survey. Sample size had been previously calculated. TMD symptoms were assessed through five questions, as recommended by the American Academy of Orofacial Pain, in an attempt to identify possible TMD. Data were derived by age and gender. Prevalence of each TMD symptom, and of combination of symptoms, was calculated. Results: At least one TMD symptom was reported by 39.2% of the individuals. Pain related to TMD was noted by 25.6% of the population. Temporomandibular joint (TMJ) sound was the most common symptom of TMD, followed by TMJ pain and masticatory muscle pain. All symptoms were more prevalent in women than in men. With men used as the reference, a relative risk (RR) of at least one TMD symptom in women was 1.31 (95% confidence interval [CI] = 1.14 to 1.52). When at least two symptoms were present, the RR was 1.93 (95% CI = 1.49 to 2.51). For three or more TMD symptoms, the RR was 2.49 (95% CI = 1.67 to 3.71). Women were also more likely than men to have TMD pain (RR = 1.78; 9% CI = 1.45 to 2.18). Conclusion: Individual symptoms, as well as a combination of TMD symptoms, are prevalent in the Brazilian urban population and are more frequent in women than in men. Additional studies should focus on risk factors for and relevance of TMD for the sufferers. J OROFAC PAIN 2010;24:270-278

Nocturnal awakening with headache and its relationship with sleep disorders in a population-based sample of adult inhabitants of Sao Paulo City, Brazil

Our aim was to estimate the prevalence of nocturnal awakening with headache (NAH) in the population of Sao Paulo City according to gender, age (20-80 years old) and socioeconomic classes and its relationship to sleep disorders, sleep parameters, anxiety, depression, fatigue, life quality and obesity. We used a population-based survey with a representative three-stage cluster sample. Questionnaires and scales were applied face-to-face, and polysomnography was performed in 1101 volunteers, aged 42 +/- 14 years, 55% women. The complaint of NAH occurring at least once a week had a prevalence of 8.4%, mostly in women, obese subjects and those aged 50-59 years-old. We observed associations of NAH with insomnia, restless leg syndrome (RLS), nightmares and bruxism, but not obstructive sleep apnea syndrome. In a logistics regression model, risk factors for NAH were female gender, odds ratio (OR) (95% confidence interval [CI]) 4.5 (2.8-7.3); obesity, OR 1.9 (1.1-3.3); age between 50 and 59 years, OR 2.4 (1.2-4.7); severe anxiety, OR 8.1 (3.6-18.1); RLS, 2.7 (1.2-5.6); and nightmares, 2.2 (1.3-3.7). Our study shows that NAH was highly prevalent in the population of Sao Paulo and suggests that this phenomenon has specific characteristics with specific risk factors: obesity, RLS and nightmares.

The Fast Alcohol Screening Test (FAST) is as Good as the AUDIT to Screen Alcohol Use Disorders

This study was aimed at assessing the psychometric qualities of the fast alcohol screening test (FAST), and at comparing these qualities to those of the alcohol use disorders identification test (AUDIT) in three samples of Brazilian adults: (i) subjects attended at an emergency department (530); (ii) patients from a psychosocial care center (40); and (iii) university students (429). The structured clinical interview for diagnosis (SCID)-IV was used as gold standard. The FAST demonstrated high test-retest and interrater reliability coefficients, as well as high predictive and concurrent validity values. The results attest the validity and reliability of the Brazilian version of the FAST for the screening of indicators of alcohol abuse and dependence.

Signs of Temporomandibular Disorders in Migraine Patients: A Prospective, Controlled Study

Objectives: To identify signs of temporomandibular disorders and cervical pain in individuals with episodic and chronic (transformed) migraine (CM), relative to controls without headaches. Methods: In this prospective, controlled, double-blind study, we examined 93 individuals divided in 3 groups: episodic migraine EM, (n= 31), CM chronic migraine (n= 34), and controls without migraine (n= 28). We recorded signs of temporomandibular disorders, and of pain in the neck, after the protocol of Helkimo (1974). We calculated the odds ratio (OR) and confidence intervals (CI) of symptoms as a function of headache status. Data from all groups were paired and compared using the chi(2) test. The level of significance was 5% in 2-tailed tests. Results: Relative to controls, participants with EM and CM were significantly more likely to have tenderness in the masticatory muscles [controls = 28%, migraine = 54%, (OR = 3.0, 95% CI = 1.1-8.9), CM = 73% (OR = 6.9, 95% CI = 2.3-21.2)], and in the temporomandibular joint [controls = 25%, migraine = 61%, (OR = 4.7, 95% CI = 1.5-14.5), CM = 61% (OR = 4.8, 95% CI = 1.6-14.5)]. They were numerically (but nonsignificantly) more likely to have limited lateral jaw movements (CM = 34%; EM = 26%; NP = 18%), joint sounds (CM = 44%; EM = 29%; NP = 28%), and tenderness in neck muscles (CM = 64%; EM = 51%; NP = 35%). Conclusion: In a tertiary care population, individuals with EM and CM are more likely to have tenderness at the temporomandibular joint and on the masticatory muscles, relative to controls. Studies are needed to investigate whether treatment of 1 disorder will improve the other.

Mitral valve prolapse and anxiety disorders

We investigated whether there is an association between anxiety disorders and mitral valve prolapse. We compared mitral valve prolapse prevalence in individuals with panic disorder (n=41), social anxiety disorder (n=89) and in healthy controls (n=102) in an attempt to overcome the biases of previous studies. Our results show no associations between panic disorder or social anxiety disorder and mitral valve prolapse, regardless of the diagnostic criteria employed, and that the relationship between these conditions seems not to be clinically relevant.

Temporomandibular Disorders Are Differentially Associated With Headache Diagnoses A Controlled Study

Objectives: Temporomandibular disorders (TMDs) are considered to be comorbid with headaches. Earlier population studies have suggested that TMD may also be a risk factor for migraine progression. If that is true, TMD should be associated with specific headache syndromes (eg, migraine and chronic migraine), but not with headaches overall. Accordingly, our aim was to explore the relationship between TMD subtypes and severity with primary headaches in a controlled clinical study. Methods: The sample consisted of 300 individuals. TMDs were assessed using the Research Diagnostic Criteria for TMD, and primary headache was classified according to International Classification for Headache Disorders-2. Univariate and multivariate models assessed headache diagnoses and frequency as a function of the parameters of TMD. Results: Relative to those without TMD, individuals with myofascial TMD were significantly more likely to have chronic daily headaches (CDHs) [ relative risk (RR) = 7.8; 95% confidence interval (CI), 3.1-19.6], migraine (RR = 4.4; 95% CI, 1.7-11.7), and episodic tension-type headache (RR = 4.4; 95% CI, 1.5-12.6). Grade of TMD pain was associated with increased odds of CDH (P < 0.0001), migraine (P < 0.0001), and episodic tension-type headache (P < 0.05). TMD severity was also associated with headache frequency. In multivariate analyses, TMD was associated with migraine and CDH (P = 0.001). Painful TMD (P = 0.0034) and grade of TMD pain (P < 0.001) were associated with headache frequency. Discussion: TMD, TMD subtypes, and TMD severity are independently associated with specific headache syndromes and with headache frequency. This differential association suggests that the presence of central facilitation of nociceptive inputs may be of importance, as positive association was observed only when muscular TMD pain was involved.

Saccadic Movements in subjects with cerebellar disorders

Saccades are part of the electrooculography tests battery. The cerebellum has important connections with the brainstem and thalamic structures involved in the generation of saccades. Aim: to study saccadic movements in subjects with cerebellar disorders. Study Method: Prospective clinical study. Materials and Methods: 11 subjects with cerebellar disorders were selected, together with a control group with 27 normal subjects. The patients of both groups had their saccadic movements registered (fixed and randomized). We compared and quantitatively analyzed the responses from both groups. Results: We did not find any differences among the quantitative parameters between the two. Age and gender did not influence these values. Despite these findings, the morphologies of the saccadic curves were very different between the two groups. Conclusion: Quantitative parameters of horizontal saccades from individuals with cerebellar diseases do not differ from those presented by normal subjects. Gender and age also did not influence these parameters.

GLOBAL POSTURAL REEDUCATION AND STATIC STRETCHING EXERCISES IN THE TREATMENT OF MYOGENIC TEMPOROMANDIBULAR DISORDERS: A RANDOMIZED STUDY

Objective: The purpose of this study was to compare 2 different interventions, global postural reeducation (GPR) and static stretching exercises (SS), in the treatment of women with temporomandibular disorders (TMDs). Methods: A total of 28 subjects with TMDs were randomized into 2 treatment groups: GPR, where therapy involved muscle global chain stretching, or SS, with conventional static stretching; but only 24 completed the study. Eight treatment sessions lasting 40 minutes each (weekly) were performed. Assessments were conducted at baseline, immediately after treatment end, and 2 months later. Measurements included pain intensity at the temporomandibular joint, headache, cervicalgia, teeth clenching, ear symptoms, restricted sleep, and difficulties for mastication, using a visual analogue scale. In addition, electromyographic activity and pain thresholds were measured at the masseter, anterior temporalis, stemocleidomastoid, and upper trapezius muscles. Two-way analysis of variance with Tukey post hoc test was used for between-group comparisons. Significance level was .05. Results: Comparing the pain assessments using the visual analogue scale, no significant differences were seen with the exception of severity of headaches at treatment end (GPR, 3.92 +/- 2.98 cm; SS, 1.64 +/- 1.66 cm; P < .024). In addition, no significant differences were seen for pain thresholds and for electromyographic activity (P > .05). Conclusions: For the subjects in this study, both GPR and SS were similarly effective for the treatment of TMDs with muscular component. They equally reduced pain intensity, increased pain thresholds, and decreased electromyographic activity. (J Manipulative Physiol Ther 2010;33:500-507)
