ABSTRACT

BACKGROUND: Computational linguistics allows an understanding of language structure and different forms of expression of patients' perceptions. AIMS: The aims of this study were (i) to carry out a descriptive analysis of the discourse of people with chronic low back pain using sentiment analysis (SA) and network analysis; (ii) to verify the correlation between patients' profiles, pain intensity and disability levels with SA and network analysis; and (iii) to identify clusters in our sample according to language and SA using an unsupervised machine learning technique. METHODS: We performed a secondary analysis of a qualitative study including participants with chronic non-specific low back pain. We used the data related to participants' feelings when they received the diagnosis. The SA and network analysis were performed using the Valence Aware Dictionary and sEntiment Reasoner, and the Speech Graph, respectively. Clustering was performed using the K-means algorithm. RESULTS: In the SA, the mean composite score was -0.31 (Sd. = 0.58). Most participants presented a negative discourse (n = 41; 72%). Word Count (WC) and Largest Strongly connected Component (LSC) positively correlated with education. No statistically significant correlations were observed between pain intensity, disability levels, SA, and network analysis. Two clusters were identified in our sample. CONCLUSION: The SA showed that participants reported their feeling when describing the moment of the diagnosis using sentences with negative discourse. We did not find a statistically significant correlation between pain intensity, disability levels, SA, and network analysis. Education level presented positive correlation with WC and LSC.

ABSTRACT

INTRODUÇÃO: A dor lombar possui alta prevalência, sendo uma das principais causas de incapacidade no Brasil e no mundo. A dor lombar apresenta etiologia multifatorial, sendo extremamente comum em trabalhadores. OBJETIVOS: Verificar o conhecimento sobre os fatores de risco para dor lombar, crenças e atitudes sobre o manejo da dor lombar entre profissionais de saúde (fisioterapeutas e ergonomistas) atuantes na área ocupacional. MATERIAIS E MÉTODOS: Foi realizado um estudo observacional transversal com 81 profissionais de saúde ocupacional brasileiros. Os participantes preencheram um questionário eletrônico composto por dados profissionais, sociodemográficos, itens sobre fatores de risco para dor lombar e a Brazilian version of the Pain Attitudes and Beliefs Scale for Physiotherapists. Conhecimentos, crenças e atitudes foram analisados por meio do teste do qui-quadrado para fatores de risco para dor lombar e um modelo de regressão linear para crenças e atitudes dos profissionais de saúde. RESULTADOS: Obesidade (7,4%), ficar sentado mais de 2 horas (8,6%), atividade física (9,9%), falta de apoio psicossocial no trabalho (11,1%) e consumo de álcool (37,0%), apresentaram os menores índices de conhecimento sobre fatores de risco da dor lombar pelos profissionais. Itens sobre saúde geral apresentaram o menor conhecimento. Uma orientação biomédica e psicossocial equilibrada de crenças e atitudes sobre o manejo da dor lombar foi observada. CONCLUSÃO: Profissionais de saúde ocupacional brasileiros carecem de conhecimento sobre os fatores de risco não ocupacionais da dor lombar, especialmente o estado geral de saúde. Esses profissionais também possuem conceitos biomédicos e psicossociais equilibrados no manejo da dor lombar.


INTRODUCTION: Low back pain (LBP) is highly prevalent and is one of the main causes of disability in Brazil and around the world. LBP presents a multifactorial etiology, being extremely common in workers. OBJECTIVE: This study aimed to verify the knowledge about the LBP risk factors, beliefs and attitudes about the management of LBP among health professionals (physiotherapists and ergonomists) working in the occupational area. MATERIALS AND METHODS: A cross-sectional observational study was conducted with 81 Brazilian occupational health professionals. Participants completed an electronic questionnaire comprising professional data, sociodemographics, items about LBP risk factors, and the Brazilian version of the Pain Attitudes and Beliefs Scale for Physiotherapists. Knowledge, beliefs and attitudes were analyzed using the chi-square test for LBP risk factors and the linear regression model for health professionals' beliefs and attitudes. RESULTS: Obesity (7.4%), sitting for more than 2 hours (8.6%), physical activity (9.9%), lack of psychosocial support at work (11.1%) and consuming alcohol (37.0%) presented the lowest rate of knowledge about LBP risk factors by professionals. Items about general health showed the lowest knowledge. A balanced biomedical and psychosocial orientation of beliefs and attitudes about managing LBP was observed. CONCLUSION: Brazilian occupational health professionals lack knowledge about non-occupational LBP risk factors, especially general health status. These professionals also have balanced biomedical and psychosocial concepts in managing LBP.

ABSTRACT

Unhealthy lifestyle choices, poor diet, and aging can have negative influences on cognition, gradually increasing the risk for mild cognitive impairment (MCI) and the continuum comprising early dementia. Aging is the greatest risk factor for age-related dementias such as Alzheimer's disease, and the aging process is known to be influenced by life events that can positively or negatively affect age-related diseases. Remarkably, life experiences that make the brain vulnerable to dementia, such as seizure episodes, neurotoxin exposures, metabolic disorders, and trauma-inducing events (e.g. traumatic injuries or mild neurotrauma from a fall or blast exposure), have been associated with negative effects on proteostasis and synaptic integrity. Functional compromise of the autophagy-lysosomal pathway, a major contributor to proteostasis, has been implicated in Alzheimer's disease, Parkinson's disease, obesity-related pathology, Huntington's disease, as well as in synaptic degeneration which is the best correlate of cognitive decline. Correspondingly, pharmacological and non-pharmacological strategies that positively modulate lysosomal proteases are recognized as synaptoprotective through degradative clearance of pathogenic proteins. Here, we discuss life-associated vulnerabilities that influence key hallmarks of brain aging and the increased burden of age-related dementias. Additionally, we discuss exercise and diet among the lifestyle strategies that regulate proteostasis as well as synaptic integrity, leading to evident prevention of cognitive deficits during brain aging in pre-clinical models.

ABSTRACT

Background: The acute clinical repercussions of SARS-CoV-2 infection have been widely studied. However, the possible late repercussions of long COVID have not yet been well defined in the literature. Objectives: To identify the presence of pain and musculoskeletal disability in patients with Long COVID and also to identify predictive factors for pain intensity in this population. Methods: In this cross-sectional and retrospective observational study individuals with Long COVID symptoms were included. It was collected musculoskeletal disability measures, data from patient-related outcome measures and variables from a COVID-19 outpatient service database. Associations and sub-group analyses were performed considering the variables pain, disability and hospitalization. Linear regression was performed to identify predictive factors for pain intensity in Long COVID patients. Results: We evaluated 195 patients and most of them (57%) presented musculoskeletal pain in one area of the body. Pain sub-group presented worse disability indices and worse clinical course during hospitalization. Hospitalized patients presented worse disability indices comparing to non-hospitalized. Significant correlations were found between pain and days of non-invasive oxygen support (r = 0.21; p = 0.003); days in intensive care unit (r = 0.22; p = 0.002) and days in invasive mechanical ventilation (r = 0.35; p = 0.001). Hospitalized individuals showed a higher chance of presenting late musculoskeletal pain (OR = 1.42: 95%CI 1.09-2.04). Days in intensive care unit (ß = 0,234: P = 0,001) and days in invasive mechanical ventilation (ß = 0.764: P = 0.001) were predictors of pain intensity [F(2,192) = 18.559; R2 = 0.231; p = 0.001]. Conclusion: Individuals with Long COVID presented musculoskeletal pain and disability. Hospitalized patients showed a greater chance of having musculoskeletal pain. Days in intensive care unit and days in invasive mechanical ventilation were predictors of late musculoskeletal pain intensity.

ABSTRACT

BACKGROUND: Insufficient sleep is common nowadays and it can be associated with chronic pain. OBJECTIVE: To describe the main polysomnographic findings in patients with chronic musculoskeletal pain and to estimate the association between sleep quality, polysomnography variables and chronic musculoskeletal pain. METHODS: This cross-sectional research analyzed a database from polysomnography type 1 exams results and then collected data via an electronic form from these patients. The form collected sociodemographic data and presented clinical questionnaires for measuring sleep quality, sleepiness, pain intensity and central sensitization signs. Pearson's correlation coefficient and odds ratio were used to estimate the associations. RESULTS: The mean age of the respondents was 55.1 (SD 13.4) years. The mean score of the Central Sensitization Inventory showed signs of central sensitization (50.1; SD 13.4) in the participants. Most patients (86%) had 1 or more nocturnal awakenings, 90% had one or more episodes of sleep apnea, 47% had Rapid Eye Movement sleep phase latency greater than 70-120 min and the mean sleep efficiency among all participants was 81.6%. The Pittsburgh Sleep Quality Index score was correlated with the CSI score (r = 0.55; 95% CI: 0.45, 0.61). People with central sensitization signs have 2.6 times more chance to present sleep episodes of blood oxygen saturation below 90% (OR = 2.62; 95% CI:1.23, 6.47). CONCLUSION: Most people with central sensitization signs had poor sleep quality, night waking episodes and specific disturbances in sleep phases. The findings showed association between central sensitization, sleep quality, nocturnal awakening, and changes in blood oxygen saturation during sleep.

ABSTRACT

BACKGROUND: In-stent restenosis remains a common and important complication after endovascular treatment of superficial femoral artery peripheral artery disease. It occurs in 14 to 35% of cases in 1 year and there is still no efficient treatment for this condition. Paclitaxel-coated balloons have shown promising results. OBJECTIVE: Investigate the 3 year results of superficial femoral artery in-stent restenosis treated with paclitaxel-coated balloon angioplasty, using the Lutonix™ 035 device. METHODS: We conducted a retrospective observational study with patients with symptomatic (Rutherford 2 to 5) superficial femoral artery in-stent restenosis, that were treated with paclitaxel-coated balloon angioplasty using the Lutonix™ 035 device, in a single center from January 2016 to December 2020. Duplex scan was used to follow the patients. Primary patency was obtained through Kaplan-Meier analysis. Mortality, and amputation rates were also evaluated. RESULTS: 105 patients were included. Two patients had technical failure and required an additional stent, and were thus excluded. 103 patients were analyzed. Primary patency was 91.26, 80.47, and 67.71%, respectively, in the first, second, and third year after the procedure. There were no deaths 30 days after the procedure. There were no major amputations during the 3 year follow-up. CONCLUSION: Paclitaxel-coated balloon angioplasty with the Lutonix™ 035 device was a safe and effective treatment to superficial femoral artery in-stent restenoses. The results were maintained along the 3 year follow-up.

ABSTRACT

OBJECTIVE: First and second violinists in orchestras use identical instruments, but the motor patterns used to execute the different notes may vary between the two groups and the biomechanical gestures may influence musculoskeletal complaints. The primary objective of this study was to compare the pain intensity and interference in musical performance of first and second violinists of professional youth chamber orchestras. Second, to investigate the correlation between pain and the musical practice profile in this population. METHODS: This cross-sectional study enrolled 74 violinists, aged 12 to 17 years, from three professional youth chamber orchestras in Brazil. Participants completed a validated self-administered questionnaire, the Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians-Brazilian version (MPIIQM-Br). Variables related to musical practice profiles were also recorded. Data analysis applied t-tests for independent samples and Pearson's correlation coefficient. RESULTS: The sample of first violinists (n=39) presented 23 males and 16 females, and the second violinists (n=35) included 23 females and 12 males. The mean age was 13.9 yrs (SD 1.1) and 14.1 yrs (1.0) for the first and second violinist groups, respectively. Most participants (n=66, 89%) reported pain in at least one moment of their career, and 54 (76%) reported pain at the time of data collection. A higher pain prevalence was identified in the right shoulder (37.7%), in 28.2% of the second violinists and 9.4% of the first. The second violinists presented higher scores for most variables related to pain intensity and pain interference in performance (p < 0.05). A correlation was observed between time working at a professional level and the number of affected areas on the body pain map (r=0.30; 95% CI 0.23-0.42) and between the hours of daily practice and the number of affected areas on the body pain map (r=0.39; 95% CI 0.29-0.45). CONCLUSION: Second violinists had more complaints of pain and difficulty in playing their instrument compared to the first violinists. The study also found a correlation between the number of body areas with pain complaints and variables linked to the violinists' practice profile.

ABSTRACT

This 2-year-follow up study compared and evaluated the stability of early anterior open bite (AOB) treatment based on different appliances. Children from 7 to 10 years with Angle Class I, AOB larger than 1.0 mm and fully erupted maxillary and mandibular permanent central incisors were eligible. The initial sample was 99 patients distributed, by simple randomization, into four groups: BS (bonded spurs), CC (chincup), FPC (fixed palatal crib) and RPC (removable palatal crib). Cephalometric analysis was performed at baseline (T1), final (T2) and 2-year post-treatment (T3) by taking the overbite measurements as the main outcome. Blinding was possible to cephalometric analysis. At T3, with dropouts, there were 63 individuals, being BS (n=15; overbite 0.19 mm; 11.54 years; 10 female (F)/5 male (M)); CC (n=11; overbite -0.19 mm; 11.41 years; 8 F/3 M); FPC (n=21; overbite 1.23 mm; 11.44 years; 15 F/6 M) and; RPC (n=16; overbite 0.73 mm; 11.67 years; 6 F/10 M). Changes in dentoskeletal variables and breaking deleterious oral habits during the follow up were statically analyzed with p<.05. Mandibular skeletal linear measurements and vertical dental components have gradually increased with age, manly at pubertal growth spurt and at the establishment of permanent dentition after treatment. Incisor teeth extrusion had impact on AOB correction and stability in 4 groups, which recorded a 1.15 mm-improvement of overbite after treatment (T3-T2). The experimental appliances were effective with stable results, being FPC the device recorded the highest AOB correction and the lowest patient withdrawal rate.

ABSTRACT

BACKGROUND: Patients' beliefs have an important influence on the clinical management of low back pain and healthcare professionals should be prepared to address these beliefs. There is still a gap in the literature about the influence of patients' perceptions of their clinical diagnosis on the severity of their pain experience and disability. OBJECTIVES: To identify the perceptions of patients with chronic non-specific low back pain regarding the influence of their clinical diagnosis on pain, beliefs, and daily life activities. METHODS: Qualitative study of 70 individuals with chronic non-specific low back pain. A semi structured interview was conducted about patients' beliefs and perceptions regarding the influence of clinical diagnosis on their daily activities and pain intensity. RESULTS: Most participants believed that higher number of different clinical diagnoses for the same individual may be associated with high pain intensity and disability for daily activities and that pain and injury are directly related. Patients beliefs were grouped into four main themes: (1) pain has multifactorial explanation in physical dimension; (2) improvement expectation is extremely low in patients with chronic pain; (3) clinical diagnosis influences pain and disability levels; (4) clinical diagnosis is extremely valued by patients. CONCLUSIONS: Patients believe that there is a strong relationship between structural changes in the lower back, pain, and daily life activities; thus, providing evidence of a strong influence of the biomedical model on their beliefs.

ABSTRACT

BACKGROUND: An accurate prediction of progression is critical to define the management of bladder cancer (BC). The ectonucleotidases CD39 and CD73 play strategic roles in calibrating purinergic signals via an extracellular balance between ATP and adenosine. The altered expression of these enzymes plays a potential role in tumor invasion and metastasis, therefore, has been proposed to be used for prognosis of solid tumor. In BC this is not yet clear. OBJECTIVE: This study aimed to evaluate CD39 and CD73 expression in a cohort of patients with non-muscle-invasive (NMI) and muscle-invasive (MI) BC regard to its association with clinicopathological features. MATERIALS AND METHODS: Retrospective clinical follow-up data and primary urothelial BC specimens of 162 patients were used (87 from patients who underwent transurethral resection and 75 from cystectomized patients). Tissue microarrays were constructed, and immunohistochemistry for CD39 and CD73 was performed to make associations with clinicopathological data. RESULTS: Overall, 96 were NMI (59.3%) and 66 MI (40.7%). CD39 immunoreactivity in BC cells was found in 72% of the cases, while CD73 was found in 97%. High CD39 expression alone was more frequent in NMI BC (p < 0.001), while CD73 expression was not powerful to predict the stage of BC. The association of both markers confirmed that only CD39 has potential in BC prognosis. CONCLUSIONS: The altered expression of CD39 presented herein supports the idea that this ectonucleotidase may be involved in bladder tumorigenesis. High expression of CD39 in tumor cells is correlated with the early stage of BC.

ABSTRACT

STUDY OBJECTIVES: To perform the cross-cultural adaptation of the Richards-Campbell sleep questionnaire (RCSQ) to Portuguese-Brazil and to eval its internal consistency, test-retest reliability, and measurement error in intensive care unit (ICU) inpatients. METHODS: The study enrolled 113 inpatients at medical/surgical ICU in Curitiba, Brazil. The RCSQ was first translated to Portuguese-Brazil according to the principles of good practice for the translation and cultural adaptation process for patient-reported outcomes and then applied in 30 inpatients. The final version (RCSQ-PT-Br) was applied to measure content validity (83 inpatients, 47 men [56.6%], 60.4 ± 14.2 years), and test-retest reliability and measurement error (a subset of 53 inpatients). Internal consistency of the RCSQ-PT-Br was estimated using Cronbach's a; test-retest reliability (2 independent rates) was assessed using the single measurement, absolute agreement, two-way random effects model (ICC2,1). RESULTS: Group-average RCSQ-PT-Br total score was 46.9 ± 26.7 (range 3.4-98.8). The RCSQ-PT-Br total score showed good content internal consistency (Cronbach's α = 0.850 95%CI = [0.789-0.897]) and excellent test-retest reliability (ICC2,1 = 0.840 95% CI = [0.739-0.904]). Measurement error was low (standard error of mean = 11 mm, mean difference = 30 mm). CONCLUSIONS: The RCSQ-PT-Br is a valid and reliable instrument to evaluate the sleep of patients hospitalized in the ICU in Brazil.

ABSTRACT

The object of this study was to compare the clinical complications of 4 different appliances used in the early treatment of anterior open bite (AOB), and to test the null hypothesis that there is no difference in the number of complications among the appliances. Records from 99 Class I malocclusion patients with AOB treated using bonded spurs, BS, n = 25; chin cup, CC, n = 25; fixed palatal crib, FPC, n = 25; and removable palatal crib, RPC, n = 24) were examined. The total number and frequency of clinical complications that occurred over 12 months were described and compared by using chi-square and Kruskal-Wallis tests (Dunn's post-test) (α = 5%, CI = 95%). The incidence of clinical complications was 66.7%, comprising: breakage, bond failure, maladjustment, allergy, soft-tissue lesion, loss of removable appliance and abandonment. Eighteen patients gave up treatment; this occurred more frequently in the groups with removable appliances. Regarding the total number of complications per patient, Group BS exhibited a significantly higher number than the other groups (p < 0.0001). A low frequency of complications (1 to 3) was found in the groups, except for Group BS, in which 8% of the patients presented moderate frequency (4 to 6). In terms of appliance types (fixed or removable), there was no difference in the incidence of complications (p > 0.094). The null hypothesis was rejected, since the BS group exhibited the highest total number and frequency of complications. There was no difference between fixed and removable appliances in terms of incidence of clinical complications, although more patients using removable appliances abandoned their treatment.

ABSTRACT

Abstract This 2-year-follow up study compared and evaluated the stability of early anterior open bite (AOB) treatment based on different appliances. Children from 7 to 10 years with Angle Class I, AOB larger than 1.0 mm and fully erupted maxillary and mandibular permanent central incisors were eligible. The initial sample was 99 patients distributed, by simple randomization, into four groups: BS (bonded spurs), CC (chincup), FPC (fixed palatal crib) and RPC (removable palatal crib). Cephalometric analysis was performed at baseline (T1), final (T2) and 2-year post-treatment (T3) by taking the overbite measurements as the main outcome. Blinding was possible to cephalometric analysis. At T3, with dropouts, there were 63 individuals, being BS (n=15; overbite 0.19 mm; 11.54 years; 10 female (F)/5 male (M)); CC (n=11; overbite -0.19 mm; 11.41 years; 8 F/3 M); FPC (n=21; overbite 1.23 mm; 11.44 years; 15 F/6 M) and; RPC (n=16; overbite 0.73 mm; 11.67 years; 6 F/10 M). Changes in dentoskeletal variables and breaking deleterious oral habits during the follow up were statically analyzed with p<.05. Mandibular skeletal linear measurements and vertical dental components have gradually increased with age, manly at pubertal growth spurt and at the establishment of permanent dentition after treatment. Incisor teeth extrusion had impact on AOB correction and stability in 4 groups, which recorded a 1.15 mm-improvement of overbite after treatment (T3-T2). The experimental appliances were effective with stable results, being FPC the device recorded the highest AOB correction and the lowest patient withdrawal rate.


Resumo Os objetivos do presente estudo foram comparar e avaliar a estabilidade do tratamento precoce da mordida aberta anterior (MAA) com diferentes dispositivos. A amostra inicial foi composta por 99 pacientes randomizados em quatro grupos experimentais: BS - esporões colados; CC - mentoneira; FPC - grade palatina fixa; RPC - grade palatina removível. Análise cefalométrica foi realizada para avaliar os dados do período inicial (T1), final do tratamento (T2) e 2 anos após tratamento (T3), sendo a variável overbite o desfecho principal. Em T3, após perdas de seguimento, haviam 63 indivíduos, sendo BS (n=15; overbite 0.19 mm; 11.54 anos; 10 Feminino (F)/5 Masculino (M)); CC (n=11; overbite -0.19 mm; 11.41 anos; 8 F/3 M); FPC (n=21; overbite 1.23 mm; 11.44 anos; 15 F/6 M) e; RPC (n=16; overbite 0.73 mm; 11.67 anos; 6 F/10 M). Comparações das alterações nas variáveis dentoesqueléticas e abandono de hábitos bucais deletérios durante o tempo de acompanhamento foram estatisticamente analisados com p<.05. Medidas esqueléticas lineares mandibulares e componentes verticais aumentaram gradualmente com a idade, principalmente com o surto de crescimento puberal e estabelecimento da dentição permanente no pós-tratamento. O overbite foi significantemente melhorado durante o tratamento, permanecendo estável com alterações positivas. A extrusão dos incisivos impactou na correção da MAA e estabilidade nos 4 grupos, que registraram uma melhora de 1.15 mm no pós-tratamento (T3-T2). Com suas limitações, todos dispositivos experimentais foram efetivos e mostraram resultados estáveis no tratamento precoce da MAA, sendo que a FPC apresentou a maior correção da MAA e o menor índice de desistência.

ABSTRACT

OBJECTIVE: To investigate whether a common measure of sagittal pelvic torsion based on the superior iliac spines behave similarly to predictions of a rigid (non-torsioned) plane, when leg length discrepancies (LLD) are induced. METHOD: Twenty-four young asymptomatic participants were subjected to pelvic posture measurements that use the anterior-superior iliac spines (ASISs) and posterior-superior iliac spines (PSISs) as references, while standing on level ground and with a one-, two- and three-centimeter lifts under the left foot. A special caliper with digital inclinometers was used. The following angles were measured: angles of the right and left PSIS-to-ASIS lines; right-left relative angle (RLRA), as the angle between the right and left PSIS-to-ASIS lines, which is a traditional lateral-view measure intended to detect sagittal torsions; angle of the inter-ASISs line; angle of the inter-PSISs line; anterior-posterior relative angle (APRA), as the angle between the inter-ASISs and inter-PSISs lines. According to trigonometric predictions based on the geometry given by the lines linking the superior iliac spines (i.e. a trapezoid plane), a pure lateral tilt of the pelvis, without interinnominate sagittal motion, would change RLRA in a specific direction and would not change APRA. RESULTS: Repeated-measures ANOVAs revealed that RLRA (p<0.001) and right and left PSIS-to-ASIS angles (p≤0.001) changed, and APRA did not change (p=0.33), as predicted. CONCLUSIONS: At least part of the sagittal torsion detected by measures that assume the PSIS-to-ASIS angles as the sagittal angles of the innominates is due to pelvic geometry and not to the occurrence of actual torsion, when LLDs are induced.

ABSTRACT

OBJECTIVE: The current study aimed to evaluate the concurrent validity and the diagnostic accuracy of the Central Sensitization Inventory (CSI) in detecting the impairment of the pain modulation in patients with chronic musculoskeletal pain. METHODS: A cross-sectional study was conducted in 267 patients with chronic musculoskeletal pain enrolled consecutively in an outpatient department. The CSI (index method) were compared with the cold pressor test, which was the psychophysical test used to assess the conditioned pain modulation (CPM), (reference standard). Spearman's correlations assessed the concurrent validity, and measurements of the diagnostic accuracy were performed. RESULTS: Ninety-three (34.8%) patients had CSI scores≥40. No significant correlation was found between CSI findings and the results of the CPT (dorsal forearm site or tibialis anterior site) was found. The cutoff point of 40 of the CSI showed values of sensitivity (35.1%, 95% CI: 22.6, 49.3) and specificity (65.2%, 95% CI: 58.4, 71.6) below 70%, and an accuracy of 59.1 (95% CI: 53.0, 65.1) when compared to the CPT to detect deficit. The ROC curve analysis yielded an area under the curve of 0.54 (95% CI: 0.45, 0.63, P>0.05). CONCLUSIONS: The CSI is a useless instrument to detect the deficit in the CPM in patients with chronic musculoskeletal pain due to the absence of correlation with the psychophysical test result and the insufficient measurements of diagnostic accuracy.

ABSTRACT

INTRODUCTION: The present study aimed to evaluate and compare the long-term stability of Class II correction with the Pendulum or Jones jig followed by fixed appliances. SETTINGS AND SAMPLE POPULATION: Group 1 comprised 20 Class II malocclusion patients with a mean initial age of 13.97 years (SD = 1.57), treated with Pendulum and fixed appliances for a mean period of 4.72 years (SD = 0.98), and mean long-term post-treatment evaluation of 4.72 years (SD = 0.97). Group 2 consisted of 18 Class II patients with a mean initial age of 13.19 years (SD = 1.26), treated with Jones jig and fixed appliances for a mean period of 3.96 years (SD = 0.92). Mean long-term post-treatment time was 5.50 years (SD = 1.57). METHODS: Lateral cephalograms were evaluated at three stages: initial (T1), final (T2) and long-term post-treatment (T3). Intragroup comparisons were performed with repeated measures ANOVA and Tukey's test and intergroup comparisons with independent t test. RESULTS: Many treatment changes were observed in both groups. From the long-term post-treatment periods, there was stability for most of the variables. Maxillary second molars and mandibular first molars extruded in the Jones jig group and slightly intruded in the Pendulum appliance group. The nasolabial angle decreased in the Pendulum group and increased in the Jones jig group. CONCLUSION: The correction of a Class II malocclusion was shown to be stable with similar long-term post-treatment results with Pendulum or Jones jig followed by fixed orthodontic appliances.

ABSTRACT

OBJECTIVE: To evaluate high-intensity focused ultrasound (HIFU) effects on anorectal physiology and fecal continence or constipation, and on quality of life (QoL). METHODS: We prospectively evaluated 26 patients with localized prostate cancer who underwent HIFU. The Rome III criteria for functional constipation, the Cleveland Clinic Florida Fecal Incontinence Score, and the Fecal Incontinence QoL Score questionnaires were answered before and after treatment. Anorectal manometry was used to evaluate resting and squeezing pressures, sustained contraction, paradoxical puborectalis contraction, rectal sensation, and rectal capacity. RESULTS: Thirteen patients underwent hemiablation and 13 underwent whole-gland ablation. There was no difference between groups regarding the Rome III criteria for functional constipation results. The Cleveland Clinic Florida Fecal Incontinence Score results showed that 3 (11.5%) of patients had mild fecal incontinence before HIFU and 5 (19.2%) had it afterward (P = .625). No patients reported poor QoL due to fecal incontinence in the Fecal Incontinence QoL Score. Anorectal manometry demonstrated no decrease in resting pressure after treatment (P = .299), while squeezing pressure significantly increased from 151.87 to 167.91 mm Hg (P = .034). The number of patients with normal sustained contraction remained the same (20 [77%]). Paradoxical puborectalis contraction was seen in 12 (46%) of the patients before the procedure and in 13 (50%) after (P = .713). Improvement in sensory parameters was not significant: first sense changed from 73.46 to 49.71 mL (P = .542) and first urge from 98.27 to 82.88 mL (P = .106). Rectal capacity had a nonsignificant decrease from 166.15 to 141.15mL (P = .073). CONCLUSION: HIFU did not cause significant changes in anorectal physiology. Fecal incontinence or constipation after HIFU was not observed via validated questionnaires.

ABSTRACT

Abstract The object of this study was to compare the clinical complications of 4 different appliances used in the early treatment of anterior open bite (AOB), and to test the null hypothesis that there is no difference in the number of complications among the appliances. Records from 99 Class I malocclusion patients with AOB treated using bonded spurs, BS, n = 25; chin cup, CC, n = 25; fixed palatal crib, FPC, n = 25; and removable palatal crib, RPC, n = 24) were examined. The total number and frequency of clinical complications that occurred over 12 months were described and compared by using chi-square and Kruskal-Wallis tests (Dunn's post-test) (α = 5%, CI = 95%). The incidence of clinical complications was 66.7%, comprising: breakage, bond failure, maladjustment, allergy, soft-tissue lesion, loss of removable appliance and abandonment. Eighteen patients gave up treatment; this occurred more frequently in the groups with removable appliances. Regarding the total number of complications per patient, Group BS exhibited a significantly higher number than the other groups (p < 0.0001). A low frequency of complications (1 to 3) was found in the groups, except for Group BS, in which 8% of the patients presented moderate frequency (4 to 6). In terms of appliance types (fixed or removable), there was no difference in the incidence of complications (p > 0.094). The null hypothesis was rejected, since the BS group exhibited the highest total number and frequency of complications. There was no difference between fixed and removable appliances in terms of incidence of clinical complications, although more patients using removable appliances abandoned their treatment.

ABSTRACT

OBJECTIVE: To assess and compare the effects produced in the maxillary dental arch by means of Connecticut intrusion arch (CIA) with or without a cinch back on the distal end of the tube of the first molars. MATERIALS AND METHODS: This study included 44 patients with a mean age of 13.1 ± 1.8 years treated for deep bite with a CIA randomly divided into two groups: group 1 (G1), 22 patients with initial mean age of 12.72 ± 1.74 years treated with the CIA in the upper arch without a cinch back on the distal surface of the tube of the first molars, and group 2 (G2), 22 patients with an initial mean age of 13.67 ± 2.03 years treated with the CIA with a cinch back. Lateral cephalograms were available before treatment (T1) and after intrusion of maxillary incisors (T2). The mean treatment period was 5.5 ± 1.45 months. Intragroup and intergroup changes in the maxillary incisor and molar positions were analyzed by paired and independent t-tests associated with the Holm-Bonferroni correction method for multiple comparisons (P < .05). RESULTS: There were significant differences between groups in terms of maxillary incisor displacement. The maxillary incisors flared labially (2.17°) and proclined (1.68 mm) in group 1, whereas a palatal inclination (-1.99°) and retroclination (-1.13 mm) was observed in group 2. No significant differences were found for the molar positions between the groups. CONCLUSIONS: The presence or absence of a distal bend in CIA affects incisor tipping and proclination during intrusion mechanics.
