Abstract: Juvenile chronic arthritis is a chronic inflammatory disease, which may cause joint or connective tissue damage and lesions of the internal organs. The disease commonly occurs before the age of 16 years, and complete remission is seen in 75 percent of patients. Juvenile chronic arthritis may be complicated by the development of pericarditis, the inflammation of the pericardium (membrane surrounding the heart). Pericarditis produces very mild or no symptoms, which resolve completely in most patients with arthritis. Because of the few symptoms of pericarditis, it is often difficult to diagnose this disorder. Autopsy studies show that the incidence of pericarditis in juvenile chronic arthritis is high, ranging from 30 to 50 percent. A rare complication of pericarditis associated with juvenile chronic arthritis is cardiac tamponade, the accumulation of excess fluid in the pericardium; two cases are described, and eight previously reported cases are reviewed. The clinical characteristics and findings of diagnostics tests including X-ray, electrocardiography, and echocardiography were similar in all cases. Two patients were treated with corticosteroid agents and underwent surgical removal of the pericardium. One of these patients died of infection 30 days after surgery, and the other died of ventricular tachycardia, an abnormally rapid heart rate arising in the ventricles of the heart. Only 6 of 10 cases of cardiac tamponade associated with juvenile chronic arthritis were successfully treated. A favorable outcome of this disorder is only possible with early diagnosis and treatment.

Abstract: Two cases of systemic juvenile chronic arthritis, complicated by cardiac tamponade and eight previously reported cases are described. The clinical features and radiological, electrocardiographic, and echocardiographic findings were similar for all cases. One patient in this series was treated with corticosteroids and underwent pericardiectomy, dying of sepsis 30 days after surgery. The other patient was also treated with corticosteroids, underwent pericardiocentesis and developed fatal ventricular tachycardia. Of the 10 cases, only six were successfully treated. Early diagnosis and appropriate treatment are essential for a favourable outcome.

Abstract: Objective: Obstructive sleep apnea (OSA) is a risk factor for a number of cardiovascular conditions. Although homocysteine (Hcy) and cysteine (Cys) are regarded as cardiovascular risk factors, few studies have analyzed Hcy and Cys plasma concentrations in patients with OSA. The aim of this study was to evaluate the role of Hcy and Cys in OSA in comparison with subjects without OSA and to determine the possible influence of obesity on these variables.Methods: Patients who submitted to polysomnography studies were recruited to engage in an 8-h fasting period for blood sample withdrawal, physical examination, ECG, and echocardiogram. A subgroup of lean patients with OSA (BMI < 25 kg/m(2)) were analyzed to rule out the influence of obesity. Fifteen patients were randomly assigned to participate in a continuous positive airway pressure (CPAP) protocol to assess the influence of OSA treatment on the obtained measurements.Results: A total of 75 patients and 75 control subjects matched for age and sex were analyzed. The Cys plasma levels were higher in patients with OSA compared with control subjects (490.16 ± 67.00 μmol/L vs 439.81 ± 76.12 μmol/L, respectively, P < .01); however, the Hcy plasma levels did not differ between groups. Cys plasma levels were also higher in the OSA lean subgroup when compared with lean control subjects (484.21 ± 71.99 μmol/L vs 412.01 ± 70.73 μmol/L, respectively, P = .009). There was a significant decrease of Cys plasma levels after 6 months of CPAP effective therapy.Conclusion: Cys is a potential biomarker of OSA in obese and nonobese patients and is reduced after effective OSA treatment.

Author: Ferreira RV, Roizenblatt S, and Szejnfeld VL
Subjects: Cross-Sectional Studies, Humans, Dentists, Health Knowledge, Attitudes, Practice, Osteoporosis diagnosis
Abstract: Background: Osteoporosis is an underdiagnosed condition, and its seriousness is not considered until severe complications arise. This study aimed to evaluate general dentists' knowledge about osteoporosis and their ability to identify patients with this disease by assessing mandibular cortical width (MCW) and mandibular cortical index (MCI) on panoramic dental radiographs using a visual method., Methods: In this cross-sectional study, an email questionnaire regarding the diagnosis and prevention of osteoporosis was sent to 20,773 dentists in 2016. Those who completed the questionnaire were invited to participate in radiomorphometric training and then to analyze the MCI and MCW of 114 panoramic radiographs of postmenopausal women who underwent both panoramic radiography and bone densitometry. Based on the radiomorphometric indices and while blinded to the densitometry results, the dentists determined whether they would indicate densitometry for these patients., Results: The response rate was 2.3%: 485 dentists completed the questionnaire, and 50 evaluated panoramic radiographs using the MCW and MCI. All of them reported some knowledge about osteoporosis, but 41.6% demonstrated a misleading conceptualization of the disease. Approximately 90% reported minimal access to this information during graduation, and only 27.0% were exposed to the topic during their postgraduate studies. Interest in osteoporosis prevention was expressed by 70.7% of the respondents, and interest in learning the radiomorphometric indices was expressed by 99.0%. The sensitivity in the detection of low bone mineral density through the MCW and MCI was 52.9%, and the specificity was 64%., Conclusions: Brazilian dentists demonstrated insufficient knowledge about osteoporosis and a low ability to detect osteopenia or osteoporosis by applying radiomorphometric indices., (© 2021.

Subjects: Aged, Cross-Sectional Studies, Female, Humans, Muscle Weakness, Spine, Walking, Gait
Abstract: Background: Trunk pelvic dissociation is fundamental to the compensatory mechanism for muscle weakness during body bending. We carried out an early investigation of gait changes in a sample of community-dwelling women ≥60 years without gait complaints. The primary objective was to correlate spine and pelvic angles with performance tests and accelerometry parameters. The secondary objective was to correlate performance tests with accelerometry., Methods: In this cross-sectional study, 54 community-dwelling women ≥60 years were subjected to Falls Efficacy Scale-International (FES-I), performance tests (Berg Balance Scale, Timed Up and Go, and Gait analysis), and radiographic analysis of sagittal alignment (Thoracic and Lumbar Cobb, Pelvic Incidence, Sacral Slope, and Pelvic Tilt angles). Gait speed was assessed in a 10-m comfortable walk, and accelerometry parameters were obtained in a 30-m walk distance., Results: The sample, aged 72 ± 6 years, exhibited moderate correlation between Sacral Slope and Step Length (+ 0.615). Sacral Slope weakly correlated with FES-I (- 0.339), Berg Balance Scale (+ 0.367), and with further accelerometry data in the AP plane: RMS, (+ 0.439) and Stride Regularity (+ 0.475), p < 0.05, all. Lumbar Cobb weakly correlated with the following accelerometry data in the AP plane: Step Length (+ 0.405), RMS, (+ 0.392), and Stride Regularity (+ 0.345), p < 0.05, all. Additionally, Stride Regularity in AP moderately correlated with FES-I (0,561, p < 0.05), among other weak correlations between performance tests and accelerometry data in AP., Conclusions: Early alterations in Sacral Slope and gait abnormalities in the AP plane may provide understanding of the early gait changes in robust older women.

Abstract: High frequency of periodic limb movements in sleep (PLMS) has been described among children with sickle cell disease (SCD), but there is little information about PLMS among adults with SCD. We aim to determine the frequency of PLMS among adults with SCD and to identify possible associations with iron status and haemolytic parameters. We analysed polysomnography on 99 adults: 74 with sickle cell anaemia (HbSS), 19 with HbSC (double heterozygosis HbS and HbC) and 6 with HbS-beta thalassaemia. Laboratory data were collected close to the time of the polysomnography examination. The prevalence of PLMS > 5/h was 70% and of PLMS > 15/h 36%, in the total group of patients. No differences were observed regarding gender, use of hydroxyurea and iron parameters. Logistic regression showed an association between PLMS > 15/h and hemolytic parameters: absolute reticulocyte count (p = 0.03) and unconjugated bilirubin (p = 0.01). Our data suggest that PLMS may be associated with manifestations of greater severity in SCD., (© 2017 John Wiley & Sons Ltd.)

Abstract: Background: We are witnessing the growth of urban populations, particularly in the developing world. São Paulo, the largest city in South America, continues to grow, and this growth is dramatically effecting the environment and human health. The aim of this study was to estimate the point prevalence of chronic pain in São Paulo city dwellers and to explore the influence of aspects related to urbanicity., Methods: A two-stage cluster randomized sample included 1100 individuals of the city of Sao Paulo, representing the population proportionally in terms of gender, age and social classes in 2007. For this observational cross-sectional study, the household sample was interviewed using validated questionnaires for sociodemographic aspects, the Beck inventories for anxiety and depression, the WHOQoL-REF for quality of life, the Chalder Fatigue Scale. Musculoskeletal pain was defined as diffuse pain or pain located in the back, joints or limbs. Data regarding sleep complaints and polysomnography were obtained from the Epidemiologic Sleep Study conducted in São Paulo city in 2007., Results: The prevalence estimate of chronic musculoskeletal pain was approximately 27%, with a female/male ratio of approximately 2.6/1. The predictors were being in the age-range of 30-39 years, low socioeconomic and schooling levels, obesity, sedentarism, fatigue, non-restorative sleep, daytime sleepiness, poor sleep quality, poor life quality, anxiety and depression symptoms. Psychological wellbeing was the main discriminator between responders with chronic musculoskeletal pain and the controls, followed by depression for the participants with poor psychological wellbeing, and fatigue, for the remaining ones. Insomnia syndrome was the third-level discriminator for those with fatigue, whereas sleep quality for those without fatigue., Conclusions: Musculoskeletal pain was frequently reported by São Paulo city dwellers and its correlates with psychological and sleep aspects are suggestive of a response to urbanicity., Trial Registration: ClinicalTrials.gov NCT00596713.

Abstract: Objective: To quantify modification of functional capacity in a three year period in a group of patients with rheumatoid arthritis (RA) using HAQ and EPM-ROM inventories., Methods: Forty patients with RA on methotrexate (MTX) as disease-modifying anti rheumatic drug (DMARD) were followed for up to three years. The functional status was assessed at the beginning and end of the period by HAQ and EPM-ROM., Results: Thirty two patients were retrieved, with initial HAQ score of 1.14±0.49 (mean±SD) and EPM-ROM score of 5.8±2.75. After an average period of three years, the HAQ score was 1.13±0.49 and EPM-ROM score, 6.81±3.66. In the subgroup of seven patients submitted to orthopedic surgery, HAQ score decreased from 0.84±0.72 to 1.64±0.56 and the EPM-ROM score, from 5.8±1.80 to 8.3±0.74. In the subgroup of non-operated patients, HAQ score varied from of 1.2±0.45 to 1.07±0.70 and EPM-ROM score, from 5.7±3.06 to 6.4±3.90., Conclusion: In a group of RA patients in use of only MTX as DMARD, there was little change on HAQ score and EPM-ROM scores over the average period of three years. Worsening functional capacity was observed in the group of operated patients in comparison to the not operated ones. This fact alerts us to the need for use of broader therapeutic regimens availability of musculoskeletal surgeries in a timely manner in patients with RA., (Copyright © 2014 Elsevier Editora Ltda.

Abstract: Objective: To assess the effect of passive body heating on the sleep patterns of patients with fibromyalgia., Methods: Six menopausal women diagnosed with fibromyalgia according to the criteria determined by the American College of Rheumatology were included. All women underwent passive immersion in a warm bath at a temperature of 36 ±1 °C for 15 sessions of 30 minutes each over a period of three weeks. Their sleep patterns were assessed by polysomnography at the following time-points: pre-intervention (baseline), the first day of the intervention (acute), the last day of the intervention (chronic), and three weeks after the end of the intervention (follow-up). Core body temperature was evaluated by a thermistor pill during the baseline, acute, chronic, and follow-up periods. The impact of this treatment on fibromyalgia was assessed via a specific questionnaire termed the Fibromyalgia Impact Questionnaire., Results: Sleep latency, rapid eye movement sleep latency and slow wave sleep were significantly reduced in the chronic and acute conditions compared with baseline. Sleep efficiency was significantly increased during the chronic condition, and the awakening index was reduced at the chronic and follow-up time points relative to the baseline values. No significant differences were observed in total sleep time, time in sleep stages 1 or 2 or rapid eye movement sleep percentage. The core body temperature and Fibromyalgia Impact Questionnaire responses did not significantly change over the course of the study., Conclusion: Passive body heating had a positive effect on the sleep patterns of women with fibromyalgia.

Abstract: Purpose: We assessed penile rigidity during sleep and the relationship of sleep abnormalities with priapism in adults with sickle cell disease., Materials and Methods: This was a case-control study of 18 patients with sickle cell disease and a history of priapism during the previous year, and 16 controls with sickle cell disease. Participants underwent overnight polysomnography and RigiScan® Plus recording to detect penile rigidity oscillations., Results: The priapism group (cases) showed a higher apnea-hypopnea index and oxyhemoglobin desaturation parameters than controls. A lower positive correlation between the apnea-hypopnea index and oxyhemoglobin desaturation time was observed in cases than in controls (Spearman coefficient ρ = 0.49, p = 0.05 vs ρ = 0.76, p <0.01), suggesting that desaturation events occurred independently of apnea. Two controls and 14 cases had a total sleep time that was greater than 10% with oxyhemoglobin saturation less than 90% but without CO(2) retention. Penile rigidity events were observed during rapid eye movement sleep and during stage 2 of nonrapid eye movement sleep, particularly in cases. The duration of penile rigidity events concomitant to respiratory events was higher in cases than in controls. Regression analysis revealed that the periodic limb movement and desaturation indexes were associated with priapism after adjusting for rapid eye movement sleep and lung involvement. Finally, oxyhemoglobin saturation less than 90% was associated with priapism after adjusting for lung involvement, hyperhemolysis and the apnea-hypopnea index., Conclusions: Oxyhemoglobin desaturation during sleep was associated with priapism history. It may underlie the distribution pattern of penile rigidity events during sleep in these patients., (Copyright © 2012 American Urological Association Education and Research, Inc.

Abstract: Background and Purpose: Combined Therapy (CT) composed of ultrasound and Interferential Therapy has been reported as a cost-effective, local analgesic intervention on tender points in Fibromyalgia (FM). This study aims to investigate the difference between CT applied once a week and twice a week in patients with FM., Method: Fifty patients with the diagnosis of FM were randomized into two groups (G1 = once a week treatment and G2 = twice a week treatment) with each group containing 25 patients. All eighteen tender points were assessed and treated with CT during each session, over a three-month time period. Interferential Therapy was modulated at 4,000 Hz of current carrier, 100 Hz of amplitude modulated frequency and at a bearable sensorial threshold of intensity. Pulsed ultrasound of 1 MHz at 20% of 2.5 W/cm² was used. For evaluation, the Visual Analogue Scale, Fibromyalgia Impact Questionnaire, Post Sleep Inventory and the tender point count were utilized, and the examiner was blinded to the group assignments., Results: G1 and G2 showed a significant improvement in Visual Analogue Scale (p < 0.0001 and p < 0.0005, respectively), Tender Points (p < 0.005 and p < 0.001, respectively), Fibromyalgia Impact Questionnaire and Post Sleep Inventory (p < 0.005 and p < 0.05, respectively). However, there was no significant difference between the two groups in all performed analyses., Conclusion: There is no advantage in increasing the number of sessions of combined therapy in terms of reducing generalized pain, quality of life and sleep quality for patients with FM., (Copyright © 2011 John Wiley & Sons, Ltd.)

Abstract: Disordered sleep is such a prominent symptom in fibromyalgia that the American College of Rheumatology included symptoms such as waking unrefreshed, fatigue, tiredness, and insomnia in the 2010 diagnostic criteria for fibromyalgia. Even though sleep recording is not part of the routine evaluation, polysomnography may disclose primary sleep disorders in patients with fibromyalgia, including obstructive sleep apnea and restless leg syndrome. In addition, genetic background and environmental susceptibility link fibromyalgia and further sleep disorders. Among nonpharmacological treatment proposed for sleep disturbance in fibromyalgia, positive results have been obtained with sleep hygiene and cognitive-behavioral therapy. The effect of exercise is contradictory, but overweight or obese patients with fibromyalgia should be encouraged to lose weight. Regarding the approved antidepressants, amitriptyline proved to be superior to duloxetine and milnacipran for sleep disturbances. New perspectives remain on the narcolepsy drug sodium oxybate, which recently was approved for sleep management in fibromyalgia.

Abstract: This study aims to evaluate the impact of neonatal arthritis on adult pain threshold, sleep and general behaviours in rats and their lactating dams. Male pups were injected in the hind paw with complete Freund's adjuvant or saline on postnatal day (PN) 1. After weaning, dams were tested for anxiety, sleep recording or hormone profiling (ACTH, corticosterone and prolactin) and brain sampling (pineal melatonin and hippocampus serotonin). At adulthood (PN90), distinct subgroups of neonatal arthritic (AR) and control rats (CR) were also assessed for anxiety and pain thresholds, sleep recording, and blood/brain sampling. Compared to their respective controls at PN12, dams of arthritic rats (DAR) showed a longer latency in expressing pup retrieval and dam-pup interaction. DAR and AR showed a lower pain threshold, anxiety-like behaviour, and sleep fragmentation. Compared to controls, DAR displayed longer sleep latency, reduced paradoxical sleep latency and sleep efficiency, a decrease in prolactin and serotonin levels and increased melatonin levels. This model of unilateral hindpaw inflammation has a wide range of long-term effects in both lactating dams and their adult offspring., (Copyright © 2010 European Federation of International Association for the Study of Pain Chapters.

Abstract: Objective: To evaluate the magnitude of effects of sildenafil on respiratory parameters and heart rate variability (HRV) in slow wave sleep (SWS) and REM sleep of patients with severe obstructive sleep apnea (OSA)., Methods: Thirteen male patients with untreated severe OSA (aged 43+/-10 years, body mass index of 26.7+/-1.9 kg/m(2)) were studied on two nights, one with sildenafil 50mg and one with a placebo, in a double-blind, randomized fashion. All-night polysomnography and HRV were simultaneously recorded. Short-term HRV measures were performed in apnea-free intervals. Respiratory parameters were separately assessed in non-REM and REM sleep and compared to total sleep time (TST). Short-term HRV analysis was conducted in samples with regular respiration obtained in SWS and REM sleep., Results: Comparing to placebo, during sildenafil night there was an increase in apnea-hypopnea index (AHI) in TST and also in non-REM and REM sleep. Increase in central AHI occurred in non-REM sleep; increase in obstructive AHI and decrease in oxyhemoglobin saturation occurred in both non-REM and REM sleep. Additionally, an increase in arousal index and in low/high frequency component of HRV ratio (LF/HF) was significant only in REM sleep. Correlation between sleep architecture and respiratory parameters were more frequent in non-REM sleep for placebo and in REM sleep for sildenafil., Conclusion: In severe OSA, the use of sildenafil 50mg at bedtime plays a detrimental role on respiratory parameters in both non-REM and REM sleep, fragmentation in REM sleep, and a prolonged increase in LH/HF component of HRV after resumption of ventilation., (Copyright 2010 Elsevier B.V.

Abstract: Objective: To evaluate the effects of sildenafil on the autonomic nervous system in patients with severe obstructive sleep apnea., Methods: Thirteen male patients with severe obstructive sleep apnea (mean age 43+/-10 years with a mean body mass index of 26.7+/-1.9 kg/m(2)) received a single 50-mg dose of sildenafil or a placebo at bedtime. All-night polysomnography and heart rate variability were recorded. Frequency domain analysis of heart rate variability was performed for the central five-minute sample of the longest uninterrupted interval of slow wave and rapid eye movement sleep, as well as for one-minute samples during apnea and during slow wave and rapid eye movement sleep after resumption of respiration., Results: Compared to the placebo, sildenafil was associated with an increase in the normalized high-frequency (HF(nu)) components and a decrease in the low/high-frequency components of the heart rate variability ratio (LF/HF) in slow wave sleep (p<0.01 for both). Differences in heart rate variability parameters between one-minute post-apnea and apnea samples (Delta = difference between resumption of respiration and apnea) were assessed. A trend toward a decreasing magnitude of DeltaLF activity was observed during rapid eye movement sleep with sildenafil in comparison to placebo (p=0.046). Additionally, DeltaLF/HF in SWS and rapid eye movement sleep was correlated with mean desaturation (s(R =) -0.72 and -0.51, respectively, p= 0.01 for both), and DeltaHF(nu) in rapid eye movement sleep was correlated with mean desaturation (s(R=) 0.66, p= 0.02) and the desaturation index (s(R=) 0.58, p = 0.047)., Conclusions: The decrease in arousal response to apnea/hypopnea events along with the increase in HF(nu) components and decrease in LH/HF components of the heart rate variability ratio during slow wave sleep suggest that, in addition to worsening sleep apnea, sildenafil has potentially immediate cardiac effects in patients with severe obstructive sleep apnea.

Abstract: Background: Obstructive sleep apnea (OSA) has been recognized as a distressing experience to the female partner, but a causal association remains controversial. Furthermore, a growing body of evidence supports a relationship of distress and sleep disruptions with musculoskeletal pain, also prevalent in middle-aged women. To test the hypothesis that sharing a bed with an OSA man may contribute to manifestations of distress and impaired sleep, we conducted a case-control study of 17 OSA wives and 17 wives of healthy sleepers., Methods: Clinical outcome variables were scores of the Fibromyalgia Impact Questionnaire (FIQ) and visual analog scales (VAS), tender point (TP) count and algometric index. Sleep outcome parameters were VAS scores for sleep quality and polysomnographic (PSG) parameters. Secondary outcomes were VAS scores for distress and marital relationship and coping strategies adopted by OSA wives. Clinical assessment and PSG scoring were conducted blindly., Results: After controlling for age and menopausal status, OSA wives exhibited lower sleep quality and higher distress scores than controls (p<0.05, all). Increase in pain threshold (TP count and algometric index) and in FIQ score were also observed, and in their PSG, there was an increase in awaken period and stage 1 amount during sleep, as well as in alpha power during slow wave sleep (p<0.05, all). These sleep parameters had substantial correlation with tiredness and poor sleep quality and were moderately correlated to pain assessments and distress scores., Conclusion: Thus, independently of age and menopausal status of the group, wives of OSA patients exhibited an increase in pain threshold, distress and impaired sleep in comparison to controls.

37. Efficacy of anodal transcranial direct current stimulation (tDCS) for the treatment of fibromyalgia: results of a randomized, sham-controlled longitudinal clinical trial.

Author: Valle A, Roizenblatt S, Botte S, Zaghi S, Riberto M, Tufik S, Boggio PS, and Fregni F
Abstract: Fibromyalgia has been recognized as a central pain disorder with evidence of neuroanatomic and neurophysiologic alterations. Previous studies with techniques of noninvasive brain stimulation--transcranial direct current stimulation (tDCS) and repetitive transcranial magnetic stimulation (rTMS)--have shown that these methods are associated with a significant alleviation of fibromyalgia-associated pain and sleep dysfunction. Here we sought to determine whether a longer treatment protocol involving 10 sessions of 2 mA, 20 min tDCS of the left primary motor (M1) or dorsolateral prefrontal cortex (DLPFC) could offer additional, more long-lasting clinical benefits in the management of pain from fibromyalgia. METHODS: Forty-one women with chronic, medically refractory fibromyalgia were randomized to receive 10 daily sessions of M1, DLPFC, or sham tDCS. RESULTS: Our results show that M1 and DLPFC stimulation both display improvements in pain scores (VAS) and quality of life (FIQ) at the end of the treatment protocol, but only M1 stimulation resulted in long-lasting clinical benefits as assessed at 30 and 60 days after the end of treatment. CONCLUSIONS: This study demonstrates the importance of the duration of the treatment period, suggesting that 10 daily sessions of tDCS result in more long lasting outcomes than only five sessions. Furthermore, this study supports the findings of a similarly designed rTMS trial as both induce pain reductions that are equally long-lasting.

Abstract: To evaluate the effect of smoking habits on sleep, data from 1492 adults referred to the Sleep Institute were accessed and divided into 3 categories of smoking status: current, former and non-smokers. Categories of pack-years (<15 and > or =15) defined smoking severity. The association of smoking status and smoking severity with sleep was analyzed for sleep parameters, especially apnea and hypopnea index (AHI) > or =5, more than 5% of total sleep time (TST) spent with oxyhemoglobin saturation (SaO2) <90%, and arousal index. The arousal index was higher among current (21 +/- 17) and former smokers (20 +/- 17) than non-smokers (17 +/- 15; P < 0.04). Former smokers had a higher percent of TST at SaO2 <90% than non-smokers (9 +/- 18 vs 6 +/- 13; P < 0.04). Former smokers with pack-years > or =15 compared to <15 exhibited higher AHI (22 +/- 24 vs 16 +/- 21; P < 0.05) and arousal index (22 +/- 19 vs 18 +/- 15; P < 0.05). Current smokers with pack-years > or =15 compared to <15 exhibited higher arousal index (23 +/- 18 vs 18 +/- 16; P < 0.05) and percent of TST at SaO2 <90% (11 +/- 17 vs 6 +/- 13; P < 0.05). Smoking status and pack-years were not associated with AHI > or =5 on logistic regression analysis, but current smokers with pack-years > or =15 were 1.9 times more likely to spend more than 5% of TST at SaO2 <90% than non-smokers (95%CI = 1.21-2.97; P = 0.005). The variability of arousal index was influenced by gender, AHI and current smokers with pack-years > or =15 (all P < 0.01). Smoking habits seem to be associated with arousal and oxyhemoglobin desaturation during sleep, but not with AHI. The effect was more pronounced in current than former smokers.

Abstract: Objective: To investigate whether active anodal transcranial direct current stimulation (tDCS) (of dorsolateral prefrontal cortex [DLPFC] and primary motor cortex [M1]) as compared to sham treatment is associated with changes in sleep structure in fibromyalgia., Methods: Thirty-two patients were randomized to receive sham stimulation or active tDCS with the anode centered over M1 or DLPFC (2 mA, 20 minutes for five consecutive days). A blinded evaluator rated the clinical symptoms of fibromyalgia. All-night polysomnography was performed before and after five consecutive sessions of tDCS., Results: Anodal tDCS had an effect on sleep and pain that was specific to the site of stimulation: such as that M1 and DLPFC treatments induced opposite effects on sleep and pain, whereas sham stimulation induced no significant sleep or pain changes. Specifically, whereas M1 treatment increased sleep efficiency (by 11.8%, P = 0.004) and decreased arousals (by 35.0%, P = 0.001), DLPFC stimulation was associated with a decrease in sleep efficiency (by 7.5%, P = 0.02), an increase in rapid eye movement (REM) and sleep latency (by 47.7%, P = 0.0002, and 133.4%, P = 0.02, respectively). In addition, a decrease in REM latency and increase in sleep efficiency were associated with an improvement in fibromyalgia symptoms (as indexed by the Fibromyalgia Impact Questionnaire). Finally, patients with higher body mass index had the worse sleep outcome as indexed by sleep efficiency changes after M1 stimulation., Interpretation: Our findings suggest that one possible mechanism to explain the therapeutic effects of tDCS in fibromyalgia is via sleep modulation that is specific to modulation of primary M1 activity.

Abstract: Objective: To investigate the relationship between clinical manifestations and sleep abnormalities in patients with juvenile rheumatoid arthritis (JRA)., Methods: Twenty-one patients with active polyarticular JRA and 20 healthy controls were enrolled consecutively. Pain and functional impairment were assessed with standardized, validated Brazilian questionnaires. Sleep evaluation was based on parent reporting of their child's sleep habits and polysomnography; subjects underwent an adaptation night in the sleep laboratory. Sleep architecture was analyzed and spectral analysis of non-rapid eye movement (REM) sleep was carried out by electroencephalography., Results: Patients with JRA exhibited higher indexes of periodic leg movements (PLM; p = 0.02), isolated leg movements (LM), and arousals, as well as increases in alpha activity in non-REM sleep (all p < 0.01), in spite of similar frequency of sleep complaints in comparison to controls. Among JRA patients, greater alpha activity in non-REM sleep was observed in the participants with greater joint involvement assessed by the Escola Paulista de Medicina-Pediatric Range of Motion Scale (p = 0.03) or joint count (p = 0.02). Correlation was observed between morning stiffness and PLM and/or LM (rS = 0.75, Sr = 0.74, p < 0.001 for both), and between self-rating scores of pain and alpha activity in non-REM sleep (rS = 0.74, p < 0.001)., Conclusion: Pain symptoms and disability are related to sleep fragmentation in patients with active polyarticular JRA.

Abstract: Painful experience is a complex entity made up of sensory, affective, motivational and cognitive dimensions. The neural mechanisms involved in pain perception acts in a serial and a parallel way, discriminating and locating the original stimulus and also integrating the affective feeling, involved in a special situation, with previous memories. This review examines the concepts of nociception, acute and chronic pain, and also describes the afferent pathways involved in reception, segmental processing and encephalic projection of pain stimulus. The interaction model of the cerebral cortex areas and their functional characteristics are also discussed.

Abstract: Multidisciplinary treatment has proven to be the best therapeutic option to fibromyalgia (FM) and physiotherapy has an important role in this approach. Considering the controversial results of electrotherapy in this condition, the aim of this study was to assess the effects of combined therapy with pulsed ultrasound and interferential current (CTPI) on pain and sleep in FM. Seventeen patients fulfilling FM criteria were divided into two groups, CTPI and SHAM, and submitted to pain and sleep evaluations. Pain was evaluated by body map (BM) of the painful areas; quantification of pain intensity by visual analog scale (VAS); tender point (TP) count and tenderness threshold (TT). Sleep was assessed by inventory and polysomnography (PSG). After 12 sessions of CTPI or SHAM procedure, patients were evaluated by the same initial protocol. After treatment, CTPI group showed, before and after sleep, subjective improvement of pain in terms of number (BM) and intensity (VAS) of painful areas (P<0.001, both); as well as objective improvement, with decrease in TP count and increase in TT (P<0.001, both). Subjective sleep improvements observed after CTPI treatment included decrease in morning fatigue and in non-refreshing sleep complaint (P<0.001, both). Objectively, PSG in this group showed decrease in sleep latency (P<0.001) and in the percentage of stage 1 (P<0.001), increase in the percentage of slow wave sleep (P<0.001) and in sleep cycle count (P<0.001). Decrease in arousal index (P<0.001), number of sleep stage changes (P<0.05) and wake time after sleep onset (P<0.05), were also observed and no difference regarding pain or sleep parameters were verified after SHAM procedure. This study shows that CTPI can be an effective therapeutic approach for pain and sleep manifestations in FM.

Abstract: Objective: To characterize the patterns of alpha electroencephalographic sleep and their associations with pain and sleep in patients with fibromyalgia., Methods: Pain and sleep symptoms of 40 female patients with fibromyalgia and 43 healthy control subjects were studied before and after overnight polysomnography. Blinded analyses of alpha activity in non-rapid eye movement (non-REM) sleep were performed using time domain, frequency domain, and visual analysis techniques., Results: Three distinct patterns of alpha sleep activity were detected in fibromyalgia: phasic alpha (simultaneous with delta activity) in 50% of patients, tonic alpha (continuous throughout non-REM sleep) in 20% of patients, and low alpha activity in the remaining 30% of patients. Low alpha activity was exhibited by 83.7% of control subjects (P < 0.01). All fibromyalgia patients who displayed phasic alpha sleep, activity reported worsening of pain after sleep, compared with 58.3% of patients with low alpha activity (P < 0.01) and 25.0% of patients with tonic alpha activity (P < 0.01). Postsleep increase in the number of tender points occurred in 90.0% of patients with phasic alpha activity, 41.7% of patients with low alpha activity, and 25.0% of patients with tonic alpha activity (P < 0.01). Self ratings of poor sleep were reported by all patients with phasic alpha activity, 58.3% of patients with low alpha activity (P < 0.01), and 12.5% of patients with tonic alpha activity (P < 0.01). Patients with phasic alpha activity reported longer duration of pain than patients in other subgroups (P < 0.01). Additionally, patients with phasic alpha sleep activity exhibited less total sleep time than patients in other subgroups (P < 0.05), as well as lower sleep efficiency (P < 0.05) and less slow wave sleep (P < 0.05) than patients with a tonic alpha sleep pattern., Conclusion: Alpha intrusion during sleep can be of different patterns. Phasic alpha sleep activity was the pattern that correlated better with clinical manifestations of fibromyalgia.

Abstract: Objective: To identify the child-mother diagnostic correlation in fibromyalgia (FM), to study sleep disturbance in juvenile FM, and to compare clinical aspects and sleep disorders between these groups., Methods: We studied 34 children with confirmed FM aged 11 +/- 1 years, 10 children with diffuse pain, and 17 age and sex matched asymptomatic controls. The respective 61 mothers were included: 34 asymptomatic and 27 with FM. All participants were subjected to clinical evaluation, a sleep questionnaire, and nocturnal polysomnography, preceded by a night of adaptation. Sleep scoring was done visually and a computerized analysis was performed for alpha, theta, and delta waves in slow wave sleep (SWS)., Results: A significant predominance of mothers with FM was observed in the group of children with FM (71%) compared to children with diffuse pain (30%) and asymptomatic children (0%). According to the sleep questionnaire, the complaints of superficial sleep and nonrestorative sleep were more prominent in mothers with FM than in children with FM, whereas motor agitation during sleep was more frequent in the children with FM. Polysomnographic anomalies were also more prominent in mothers with FM than in children with FM in terms of decrease in sleep efficiency, increase of number of arousals during sleep, and alpha intrusion in SWS. Both FM groups presented an increased alpha + theta time/delta time index during SWS compared to respective controls, and mothers with FM also showed an increase in alpha time/delta time index during SWS, compared to asymptomatic mothers. A correlation was found between alpha + theta time/delta time index during SWS and intensity of clinical manifestations of pain and sleep anomalies in children and their mothers., Conclusion: Significant concordance was observed regarding FM diagnosis in children and their mothers. Sleep complaints and polysomnography findings were less prominent in affected children compared to mothers with FM. In addition, we observed a significant correlation between polysomnographic indexes, sleep anomalies, and pain manifestations in children and their mothers.

Abstract: Hidden 19S IgM rheumatoid factor (RF) and 7S IgG RF were assayed in 24 children with juvenile chronic arthritis (JCA) and 26 controls, in whole sera and in the IgM and IgG containing fractions of the serum after separation by acid gel filtration. When non-fractioned serum was used, IgM RF detection was positive in 4.2% by latex fixation test and 4.2% by ELISA. IgG RF was positive in 91.7% by ELISA. In the IgM containing fraction of the serum, the positivity for IgM RF was 41.7% by LFT and 54.2% by ELISA. In the IgG containing fraction the positivity for IgG RF was 100%. These results suggest toward the need of previous serum dissociation before hidden 19S IgM RF is assayed and demonstrate high prevalence of 7S IgG RF.

Abstract: 99mTc-pyrophosphate musculoskeletal imaging and 99mTc-red blood cell gated blood pool imaging were performed on 10 patients with documented polymyositis/dermatomyositis. Abnormal 99mTc-pyrophosphate uptake by peripheral muscles was found in 8 patients (6 mild, 2 marked). Cardiac uptake occurred in 5 patients and was 3+ in 2 with cardiovascular symptoms. These 2 patients also had abnormal EF on gated blood pool imaging. Patients without myocardial 99mTc-pyrophosphate uptake had normal EF. Patients with myocardial 99mTc-pyrophosphate uptake had abnormal wall motion, in proportion to the degree of uptake. Response to therapy and outcome were poorer in patients with marked scintigraphic changes. These findings suggest that the magnitude of 99mTc-pyrophosphate myocardial uptake may have prognostic implications in these patients.
