Influência da estratégia de Estimulação Auditiva Rítmica com música associada à fisioterapia sobre os sintomas depressivos no Parkinson / Influencia de la estrategia de Estimulación Auditiva Rítmica con música asociada a fisioterapia en los síntomas depresivos en el Parkinson / Influence of Rhythmic Auditory Stimulation using music associated with physical therapy on depressive symptoms in Parkinson's

RESUMO A sintomatologia depressiva (SD) é comum na doença de Parkinson (DP) e considerada fator importante para má qualidade de vida e incapacidade do indivíduo. Intervenções terapêuticas baseadas em ritmo e música, a exemplo da Estimulação Auditiva Rítmica (EAR), têm sido utilizadas no tratamento da mobilidade e parecem influenciar positivamente o estado de humor do paciente. O objetivo deste estudo é avaliar o efeito da EAR com música associada à fisioterapia no estado de humor de pessoas com DP, com ênfase na SD. Trata-se de estudo quase experimental, com amostra de 18 pacientes com idades entre 40 e 80 anos e diagnóstico clínico de DP idiopática nos estágios leve a moderado. Os pacientes foram randomizados em dois grupos: grupo EAR e grupo-controle (GC). A SD foi avaliada por meio da versão em português do Inventário de Depressão de Beck (BDI). Os escores do BDI apresentaram redução em ambos os grupos. Entretanto, apenas no grupo EAR essa redução foi significativa, com diferença média no escore três vezes maior do que no GC.

RESUMEN La sintomatología depresiva (SD) es frecuente en la enfermedad de Parkinson (EP) y se considera un importante factor para predecir la mala calidad de vida y la discapacidad del individuo. Las intervenciones terapéuticas basadas en el ritmo y la música, como la Estimulación Auditiva Rítmica (EAR), se han utilizado en el tratamiento de la movilidad y pueden influir positivamente en el estado de ánimo del paciente. El objetivo de este estudio es evaluar el efecto de la EAR con música asociada a la fisioterapia en el estado de ánimo de personas con EP, con énfasis en la SD. Se trata de un estudio cuasiexperimental, realizado con una muestra de 18 pacientes de entre 40 y 80 años de edad, con diagnóstico clínico de EP idiopática en estadios leve a moderado. Los pacientes se dividieron al azar en dos grupos: Grupo EAR y grupo control (GC). La SD se evaluó mediante la versión en portugués del Inventario de Depresión de Beck (BDI). Las puntuaciones del BDI tuvieron una disminución en ambos grupos. Sin embargo, esta reducción fue significativa solo en el grupo EAR, con una diferencia media en la puntuación tres veces mayor que en el GC.

ABSTRACT Depressive symptoms are commonly found in Parkinson's disease and are considered an important factor for an individual's poor quality of life and disability. Therapeutic interventions based on rhythm and music, such as rhythmic auditory stimulation, have been used to treat the mobility and seem to positively influence on mood. This study aims to evaluate the effect of rhythmic auditory stimulation using music associated with physical therapy on mood in individuals with Parkinson's, with an emphasis on depressive symptoms. This is a quasi-experimental study with a final sample of 18 patients aged 40-80 years, with a clinical diagnosis of idiopathic Parkinson's disease, in the mild to moderate stages of the disease. Patients were randomized into two groups: Rhythmic Auditory Stimulation and Control Groups. Depressive symptoms were assessed using the Portuguese version of the Beck Depression Inventory. Both groups reduced their The Beck Depression Inventory scores. However, only in the Rhythmic Auditory Stimulation Group the reduction was significant, with a mean difference in the inventory score three times greater than the Control Group.

Apego materno-fetal e transtornos psiquiátricos em gestantes com fetos malformados / Maternal-fetal attachment and psychiatric disorders in pregnant women with malformed fetuses

OBJETIVO: Determinar a prevalência e os fatores associados aos sintomas de ansiedade e depressão e ao apego materno-fetal em gestantes com diagnóstico de malformações congênitas. MÉTODOS: Estudo prospectivo de corte transversal realizado durante o período de dezembro/2019 a março/2020. Foram incluídas 77 gestantes com diagnóstico de malformação fetal atendidas no Instituto de Medicina Integral Prof. Fernando Figueira (IMIP) e excluídas aquelas < 18 anos e as que sabiam o diagnóstico da malformação há menos de três semanas. Aplicou-se um questionário com variáveis sociodemográficas e clínicas, além da Escala Hospitalar de Ansiedade e Depressão e da Escala de Apego Materno-Fetal. Para análise estatística, foi aplicado o modelo de regressão logística multivariado com nível de significância de 5%. RESULTADOS: Entre as gestantes, 46,8% possuíam sintomas ansiosos e 39%, depressivos, sendo o apego materno-fetal médio em 54,5% e alto em 45,5%. Antecedentes de ansiedade e depressão e não possuir religião foram associados a maior risco de sintomas de ansiedade e depressão, e saber da malformação há ≥ 10 semanas associou-se apenas ao risco de ansiedade e ter gestação múltipla associou-se apenas ao risco de depressão. O apego materno-fetal não foi associado a ansiedade ou depressão. CONCLUSÃO: Observou-se alta prevalência de sintomas ansiosos e depressivos em gestantes com fetos malformados, além da presença de apego materno-fetal médio/alto em todas pacientes, porém sem associação com os transtornos psiquiátricos estudados. Diante disso, urge a necessidade da criação de novas linhas de cuidado voltadas à saúde mental dessas mulheres.

OBJECTIVE: To determine the prevalence and factors associated with anxiety and depression symptoms and maternal-fetal attachment in pregnant women diagnosed with congenital malformations. METHODS: Prospective cross-sectional study conducted from December/2019 to March/2020. Seventy-seven managers with a diagnosis of fetal malformation attended at the Instituto de Medicina Integral Prof. Fernando Figueira (IMIP) and those under 18 years of age who did not know the diagnosis of malformation in less than 3 weeks were excluded. Applicable to a questionnaire with clinical and sociodemographic variables, in addition to the Hospital Anxiety and Depression Scale and Maternal- -Fetal Attachment Scale. For statistical analysis, the multivariate logistic regression model was applied with a 5% significance level. RESULTS: Among pregnant women, 46.8% had anxiety symptoms and 39% depressive symptoms, with average maternal-fetal attachment at 54.5% and high at 45.5%. History of anxiety and depression and cannot use religion have been associated with an increased risk of anxiety and depression, whereas malformation saber for ≥ 10 weeks, associated only with risk of anxiety and multiple pregnancy only in depression. Maternal-fetal attachment was not associated with anxiety or depression. CONCLUSION: If there is a high prevalence of anxious and depressive symptoms in pregnant women with malformed fetuses, in addition to the presence of medium maternal-fetal/high attachment in all patients, with no association with the studied psychiatric disorders. Therefore, request the creation of new lines of care aimed at the mental health of these women.

Abstract Objectives To identify factors associated with antiparkinson drugs use and adherence in older adults with Parkinson's disease (PD) through an integrative literature review. Method An integrative literature review involving a search for relevant publications in Portuguese, English, and Spanish on the electronic databases LILACS, MEDLINE - via PubMed, Web of Science and Scopus, without restriction regarding date or study design, was carried out during the period August-September 2021. The selection of studies was performed independently by two reviewers and the final validation conducted by a third reviewer. Results After applying the eligibility criteria, 5 of the 460 studies found were included in the review. Results showed moderate adherence rates (range 35.3-66.8%) and the main factors associated with lower adherence to antiparkinson therapy were older age, cognitive deficit, greater motor impairment, multimorbidities, change in therapy regimens, depression, polypharmacy, lower education, non-white ethnicity and male gender. Factors associated with greater adherence were younger age, white ethnicity, no change in therapy regimen, higher level of knowledge about PD, good clinical control, higher educational level, married status, higher income and greater level of awareness. Conclusions Non-adherence to antiparkinsonian therapy was frequent and multifactorial., Understanding this behavior is important to help inform the scientific community and devise public policies and strategic planning in health services for improving the quality of life of the older population.

CIITA gene polymorphism (rs3087456) in systemic lupus erythematosus and rheumatoid arthritis: A population-based cohort study.

Systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) are influenced by genetic variants in immune system HLA genes. The Class II Major Histocompatibility Complex Transactivator (CIITA) is an important co-activator of the HLA transcriptional complex; the single nucleotide variant (SNV) rs3087456 localized in the gene promoter region (-168 A/G) has been reported as able to modify its transcription level. In our study, we assessed CIITA rs3087456 SNV in 1,044 Brazilians from two Brazilian regions (Northeast and South) to verify the association with susceptibility and clinical manifestations of (SLE) and (RA) using TaqMan SNP Genotyping Assays System. We observed a protection for a recessive model (GG x AA+AG) for RA susceptibility and increased risk for erosion development in AG genotype patients. No significant association was observed for SLE susceptibility; however, we observed significant increased risk for Class IV and V nephritis development in G allele and GG genotype patients. In conclusion, we showed the contribution of CIITA rs3087456 to SLE or RA clinical features and RA susceptibility in the studied populations.

Sociodemographic Profile of Elderly People with Temporomandibular Disorder and Depression in Combination with Parkinson's Disease

ABSTRACT Objective: To describe the sociodemographic profile of elderly people with temporomandibular disorder and depression in Parkinson's disease cases. Material and Methods: It is a cross-sectional cohort cut study, which used secondary data from 124 elderly people with Parkinson's disease (PD). To diagnose temporomandibular disorder (TMD), the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) questionnaire was used, and the variables studied were: age, sex, race, education, marital status, family income, stage of the disease, and depression. The statistical analysis performed was descriptive and used absolute numbers and a frequency count. Results: After the application of the eligibility criteria, the patient records of 81 elderly people with Parkinson's disease were selected; 15 presented associated TMD and depression. The average age was 69 years old; 66.67% were male; 46.67% had more than 9 years of schooling; 60% were married or had a partner; 53.33% received between 1 and 2 minimum wages; 33.33% stated they were brown; 80% were in the moderate stage of the disease; 46.66% were in group II according to the RDC/TMD, presenting disk displacement; and 53.33% presented severe depression. Conclusion: It was verified that the elderly people with Parkinson's and associated TMD and depression were male, married or with a partner, on a low income, with nine or more years of schooling, and were in the moderate stage of the disease.

Pharmacogenetic profile and the development of the dyskinesia induced by levodopa-therapy in Parkinson's disease patients: a population-based cohort study.

Levodopa-induced dyskinesia (LID) is an adverse effect that negatively impacts the quality of life of patients with Parkinson's disease (PD). Studies report that genetic variations in the genes of the pharmacogenetic pathway of the levodopa (L-DOPA) might be associated with LID development. The goal of the present study was to investigate a possible influence of functional genetic variants in the DRD1 (rs4532), DRD2 (rs1800497), DAT1 (rs28363170), and COMT (rs4680) genes with LID development. A total of 220 patients with idiopathic PD were enrolled. The genotyping for DRD1 (rs4532), DRD2 (rs1800497), DAT1 (rs28363170), and COMT (rs4680) polymorphisms were performed using Restriction Fragment Length Polymorphism (PCR-RFLP). Univariate and multivariate analyses were performed to assess the association of these polymorphisms and risk factors with LID development. Multivariate Cox regression analysis showed increased risk to LID development for both Levodopa Dose Equivalency (LED) (Hazard ratios (HR) = 1.001; 95% CI 1.00-1.01; p = 0.009) and individuals carrying the COMT L/L genotype (HR = 2.974; 95% CI 1.12-7.83; p = 0.010). Furthermore, when performed a Cox regression analysis adjusted for a total LED, we observed that the genotype COMT L/L had a 3.84-fold increased risk for LID development (HR = 3.841; 95% CI 1.29-11.37; p = 0.012). Our results suggest that before treating LID in PD patients, it is important to take into consideration genetic variant in the COMT gene, since COMT LL genotype may increase the risk for LID development.

Abstract Objective Identify the factors associated with the Nutritional Status of old people with Parkinson's disease (PD) through an integrative literature review. Method The databases LILACS, MEDLINE, BDENF, Scielo and Pubmed were used with no filters for year of publication nor study design. We included the studies with old population (age ≥60 years) in Portuguese, English or Spanish. Studies not addressing the subject, publications not available in full, and those that did not answer the guiding question were excluded. In addition to the associated factors, information regarding the objectives, study design, investigated sample, instruments for nutritional assessment, and main results were extracted. The methodological quality of the studies was assessed by the instruments Critical Appraisal Skill Program and Agency for Health care and Research and Quality. To summarize the associated factors, the percentage of studies whose intergroup analysis, association or correlation was significant for the expected outcome was considered. Results The final analysis resulted in 8 papers. The factors associated with the Nutritional Status among the PD-related clinical variables were duration and severity of the disease, motor symptoms, and cognitive function. Regarding the clinical-nutritional variables, they were associated with body fat, biochemical parameters, physical, domestic and mobility activities, energy intake, and eating habits. Conclusion Weight loss in PD is a complex and multifactorial consequence, and the early diagnose of nutritional changes in these patients is essential. Further studies in this population are necessary in order to better understand this process of weight loss in old patients with PD.

Chronic pain and depression as factors associated with temporomandibular dysfunction in older adults with Parkinsons disease / Dor crônica e depressão como fatores associados à disfunção temporomandibular em pessoas idosas com doença de Parkinson

ABSTRACT Purpose: to investigate whether chronic pain and depression are factors associated with temporomandibular dysfunction (TMD) in older adults with Parkinson's disease. Methods: a cross-sectional study using the Research Diagnostic Criteria for Temporomandibular Disorders questionnaire. The clinical variables studied were chronic pain, depression, nonspecific physical symptoms including and excluding items of pain, and dentures use. The associations between the dependent and independent variables were evaluated by the chi-square odds ratio, with a 95% confidence interval. Results: a total of 81 older adults met the eligibility criteria - 67% were males, 74% were married or had a partner, 43% reported earning 1 to 2 minimum wages, and 47% were in the moderate stage of Parkinson's disease. TMD was identified in 22% of the sample, 12% reporting chronic pain. The statistical analysis showed an association between TMD and chronic pain (p = 0.001, OR = inf, 95% CI = 12.13 - inf) and between TMD and moderate-to-severe depression (p = 0.014, OR = 4.8, 95% CI = 1.14 - 23.51). Conclusion: it was verified that chronic pain and moderate-to-severe depression were the factors associated with TMD in older adults presented with Parkinson's disease.

Respiratory muscle strength and lung function in the stages of Parkinson's disease.

OBJECTIVE: To investigate parameters of lung function and respiratory muscle strength in different stages of Parkinson's disease (PD), as well as to determine their correlation with motor function and quality of life. METHODS: This was a cross-sectional study conducted at a referral center for PD in the city of Recife, Brazil. Respiratory muscle strength and lung function, as well as their relationship with motor function and quality of life, were evaluated in patients with PD, stratified by the level of severity, and were compared with the data obtained for a control group. After confirming the normality of data distribution, we performed one-way ANOVA with a post hoc t-test. RESULTS: The sample comprised 66 individuals, in two groups: PD (n = 49) and control (n = 17). All of the parameters investigated showed inverse correlations with PD severity, and there were significant differences among the levels of severity, as well as between the PD and control groups, in terms of the MIP, MEP, FVC, FEV1, and FEF25-75%. The lung function parameters also showed moderate to weak inverse correlations with bradykinesia and rigidity. On a quality of life questionnaire, the total score and mobility domain score both presented a moderate inverse correlation with FVC, FEV1, PEF, and MEP. CONCLUSIONS: Respiratory muscle strength and some lung function parameters are impaired from the early stages of PD onward, bradykinesia and rigidity being the cardinal signs that correlate most strongly with impairment of those parameters. Such alterations negatively affect the quality of life of patients with PD.

Influence of DRD1 and DRD3 Polymorphisms in the Occurrence of Motor Effects in Patients with Sporadic Parkinson's Disease.

Parkinson's disease (PD) is a multisystem disorder that affects 2-3% of the population ≥ 65 years of age. The main pharmacologic agent use in the treatment of clinical symptoms of PD is levodopa (L-DOPA). However, the chronic use of L-DOPA might result in the emergence of motor complications such as motor fluctuation and dyskinesia. Previous studies have shown that the inter-individual variability and pharmacogenetic profile of PD patients seem to influence the occurrence of motor complications. For these reasons, the purpose of this study was to evaluate a possible relationship between DRD1 A48G and DRD3 Ser9Gly genetic variants with the occurrence of motor complications in PD patients in a Brazilian population. A total of 228 patients with idiopathic PD were enrolled. Patients were genotyped for DRD1 A48G and DRD3 Ser9Gly polymorphisms using PCR-RFLP. The univariate and multivariate analyses were performed to assess the association of these polymorphisms with the occurrence of motor fluctuation and dyskinesia in PD patients. Multiple Poisson regression analyses showed a protector effect to the occurrence of dyskinesia for individuals carrying of the DRD1 G/G genotype (PR 0.294; CI 0.09-0.87; p ≤ 0.020) after the threshold Bonferroni's. Besides, we verified risk increased to the occurrence of motor complications with daily L-DOPA dosage, disease duration, and users of rasagiline, selegiline, or entacapone (p < 0.05 for all). Our results suggest that the DRD1 A48G polymorphism and the presence of extrinsic and intrinsic factors may role an effect in the occurrence of dyskinesia in PD patients.

Pharmacogenetic Profile and the Occurrence of Visual Hallucinations in Patients With Sporadic Parkinson's Disease.

Visual hallucinations are significant nonmotor symptoms in the course of treatment of Parkinson's disease. Previous studies have shown that the interindividual variability and pharmacogenetic profile of Parkinson's disease patients seem to influence the occurrence of visual hallucinations. In our study, we investigated a possible relationship of sequence variants in DRD1, DRD2, DRD3, DAT1, and COMT genes with the presence of visual hallucinations in Parkinson's disease patients. A total of 224 Brazilian patients from the Pro-Parkinson service at the Clinical Hospital of the University of Pernambuco, diagnosed with sporadic Parkinson's disease, were enrolled. Parkinson's disease patients were divided into 2 groups based on the presence or absence of visual hallucinations. The sequence variants for DRD1, DRD2, DRD3, DAT1, and COMT were determined through the polymerase chain reaction-restriction fragment length polymorphism technique. Multiple Poisson regression analyses showed that individuals carrying the DRD3 Ser/Ser and Ser/Gly genotypes presented increased prevalence ratios of visual hallucinations (9.7-fold and 4.4-fold, respectively; P < .001). Regarding DAT1 rs28363170, there was a 9.82-fold increase in the prevalence ratio in patients with the 10/11 genotype, 8.78-fold for the 10/8 genotype, and 2.44-fold for the 9/8 genotypes (P < .001, for all). In addition, visual hallucinations were also associated with use of transdermal patches with rotigotine (PR, 3.7; 95%CI, 1.2-10.9; P = .017) and rasagiline (PR, 2.8; 95%CI, 1.3-6.0; P = .006). Our results suggest that the genetic variants DRD3 and DAT1, along with other therapeutic confounders, may influence the prevalence ratio of visual hallucinations.

The influence of SLC6A3 and DRD2 polymorphisms on levodopa-therapy in patients with sporadic Parkinson's disease.

OBJECTIVES: The aim of this study was to evaluate a possible relationship between DRD2/ANKK1 (rs1800497) and SLC6A3/DAT1 (rs28363170) gene polymorphisms with the response to levodopa (L-DOPA)-therapy in patients with Parkinson's disease (PD). METHODS: One hundred and ninety-five patients with idiopathic PD were investigated. Patients were genotyped for rs1800497 and rs28363170 polymorphisms using PCR-RFLP. Logistic regression was performed to assess the association of polymorphisms with the occurrence of the chronic complications of L-DOPA therapy. KEY FINDINGS: Our results showed association between the occurrence of dyskinesia with an increased greater disease severity (P = 0.007), higher L-DOPA dose (P = 0.007) and use of dopamine agonist (P = 0.020). Moreover, there were significant protective effects for age (P = 0.004) and male subjects (P = 0.006). CONCLUSIONS: Clinical and demographic characteristics of Brazilian PD patients and differences in DRD2 and DAT1 genes may to determine individual variations in the therapeutic response to L-DOPA in the Brazilian PD patients.

Demographic and clinical variables as differentiating predictors of cognitive disorders in Parkinson's disease / Variáveis demográficas e clínicas como preditoras diferenciais de alteração cognitiva na doença de Parkinson

Abstract Objective: to analyze demographic and clinical variables as predictors of cognitive disorders in Parkinson's disease (PD). Method: a cross-sectional descriptive study was carried out at the Pro-Parkinson Program of the Hospital das Clínicas of the Federal University of Pernambuco. The instruments used were the Mini Mental State Examination (MMSE), Scales for Outcomes in Parkinson's disease - Cognition (SCOPA-COG), the Hoehn & Yahr Staging Scale (HY), the Unified Parkinson's Disease Rating Scale part 3 (UPDRS-III), and the 15-item Yesavage Geriatric Depression Scale (GDS-15). A multiple linear regression model was used for the predictive outcome and the Mann-Whitney test was used to compare the elderly and the non-elderly groups. Results: the sociodemographic data of 85 people were collected and the participants underwent a cognitive profile evaluation (MMSE and SCOPA-COG) and clinical evaluation (HY, UPDRS-III, GDS-15). Multiple regression analysis found significant results for age, work activity, and tremor index, explaining 59% of the variability of SCOPA-COG. There was an inverse correlation with age and work activity and a direct correlation with tremors. The SCOPA-COG and MEEM scores were significantly lower in elderly patients, with an emphasis on executive functions. Conclusion: the predictors of cognitive impairment were age, work activity, and tremors. Cognitive impairment was greater in elderly patients with PD, especially for executive functions.

Métodos: Estudo de corte transversal realizado em um serviço de referência para DP em Recife (PE). Foram avaliadas a força muscular respiratória e a função pulmonar, assim como suas relações com a funcionalidade e a qualidade de vida, em pacientes com DP estratificados por gravidade da DP e comparados a um grupo controle. Após a verificação da normalidade da amostra, foi realizada one-way ANOVA e teste t post hoc. Resultados: A amostra foi composta por 66 indivíduos, sendo 49 no grupo DP e 17 no grupo controle. Houve reduções nos parâmetros investigados com a progressão da doença, em comparação com o grupo controle, sendo encontradas diferenças significativas em PImáx, PEmáx, CVF, VEF1 e FEF25-75% em todos os estágios da DP. Houve correlações inversas (de fraca a moderada) de alguns parâmetros estudados com bradicinesia e rigidez. Os escores totais do questionário de qualidade de vida e de seu domínio mobilidade apresentaram moderada correlação inversa com CVF, VEF1, PFE e PEmáx. Conclusões: A força muscular respiratória e alguns parâmetros de função pulmonar encontram-se reduzidos desde os estágios iniciais da DP, sendo a bradicinesia e a rigidez os sinais cardinais mais correlacionados ao prejuízo desses parâmetros. Essas alterações repercutem negativamente na qualidade de vida desses pacientes.

Complex regional pain syndrome in the orofacial region. Case report / Síndrome complexa de dor regional em região orofacial. Relato de caso

ABSTRACT BACKGROUND AND OBJECTIVES: The complex regional pain syndrome is characterized by presenting autonomic, sensory and motor difficult to control changes of the chronic evolution. Its pathophysiology and treatment are not fully defined, and the search for an increasingly effective treatment is a subject of medical concern. The involvement of the orofacial region has an even rarer incidence, and the literature reports only 14 cases in five decades. The objective of this report was to warn physicians and researchers about the importance of a correct diagnosis and to show the possibility of controlling this dysfunction with conservative treatment. CASE REPORT: A 68-year-old female patient, who after a facial trauma and three subsequent surgical procedures, developed orofacial complex regional pain syndrome. Several therapeutic regimens were performed, and after the last one she became completely asymptomatic: oxcarbazepine (900mg/day), morphine-controlled liberation (120mg/day), fluoxetine (40mg/day) and clonazepam (2mg/day), electrotherapy and oral rehabilitation. CONCLUSION: The diagnosis criteria for complex regional pain syndrome recommended by the International Association for the Study of Pain, revised in 2007, should be followed. The treatment of this neuropathic syndrome includes anticonvulsants, tricyclics, opioids, electrotherapy and somatic and stellate ganglion block, the latter when the pain is maintained by the sympathetic nervous system. In this report of an orofacial complex regional pain syndrome II, pain control was shown without the need for sympathetic ganglion block, which can be a warning to the medical class to a correct diagnosis and an effective and less invasive treatment.

RESUMO JUSTIFICATIVA E OBJETIVOS: A síndrome complexa de dor regional se caracteriza por apresentar alterações autonômicas, sensitivas e motoras de evolução crônica de difícil controle. Sua fisiopatologia não está totalmente definida e a busca por um tratamento cada vez mais eficaz é objeto de preocupação médica. O comprometimento da região orofacial tem uma incidência ainda mais rara e a literatura relata apenas 14 casos em cinco décadas. O objetivo deste relato foi alertar médicos e pesquisadores para a importância de um diagnóstico correto e mostrar a possibilidade de controle dessa disfunção com o tratamento conservador. RELATO DO CASO: Paciente do sexo feminino, 68 anos, após trauma facial e três intervenções cirúrgicas posteriores, desenvolveu quadro de síndrome complexa de dor regional orofacial. Foram realizados vários esquemas terapêuticos, o último dos quais tornou-a completamente assintomática: oxcarbazepina (900mg/dia), morfina de liberação controlada (120mg/dia), fluoxetina (40mg/dia) e clonazepam (2mg/dia), eletroterapia e reabilitação oral. CONCLUSÃO: Os critérios de diagnóstico para a síndrome complexa de dor regional, preconizados pela International Association for the Study of Pain, revisados em 2007, devem ser seguidos. O tratamento desta síndrome neuropática inclui anticonvulsivantes, tricíclicos e opioides, eletroterapia, bloqueio somático e de gânglio estrelado, este último quando a dor for mantida pelo sistema nervoso simpático. Neste relato de uma síndrome complexa de dor regional II orofacial foi mostrado o controle da dor sem a necessidade de bloqueio do gânglio simpático, o que pode alertar a classe médica para um correto diagnóstico e um tratamento eficaz e menos invasivo.

Conhecimentos, atitudes e práticas de pessoas com doença de parkinson sobre um programa terapêutico domiciliar com orientação em grupo / Knowledge, attitudes and practices of people with parkinson's disease about a home-based therapeutic program with group guidance

Introdução: Exercícios domiciliares são uma opção terapêutica acessível para pacientes com doença de Parkinson que apresentam dificuldade de locomoção. Serviços de fisioterapia utilizam palestras e manuais como forma de orientar a prática destes exercícios, mas carecem de avaliar o que está de fato sendo compreendido pelo paciente. Objetivo: Investigar conhecimentos, atitudes e práticas de pessoas com doença de Parkinson sobre um programa de exercícios terapêuticos domiciliares autossupervisionados com orientação em grupo. Métodos: Trata-se de um estudo transversal realizado com pessoas com doença de Parkinson idiopática leve e moderada, em um Programa de referência em um hospital universitário do nordeste do Brasil. Palestras e manual são disponibilizados pelo Programa desde 2012. Foram coletados: dados sociodemográficos, da doença, assistência e hábitos (ficha geral); conhecimentos, atitudes e práticas sobre exercícios fisioterapêuticos do manual (Inquérito Conhecimentos, Atitudes e Práticas) e barreiras associadas à prática (questionário estruturado). Utilizou-se o software BioEstat 5.0 para estatística descritiva e testes de associação, p ≤ 0,05. Resultados: Foram avaliados 28 pacientes (63 ± 7,4 anos) com tempo de diagnóstico médio de 4,5 (± 2,1) anos e maior prevalência do estágio HY 2 (71,4%). A maioria frequentava o Programa há pelo menos 1 ano (85,7%), era sedentária (60,7%) e relatava como principais entraves para a realização de sessões de fisioterapia a dificuldade financeira (92,8%) e de locomoção (53,6%). A adesão às palestras de fisioterapia foi de 60,7%. A maioria apresentou conhecimentos (60,7%) e atitudes (96,4%) adequados, entretanto, práticas inadequadas (53,6%) acerca dos exercícios terapêuticos domiciliares autossupervisionados orientados em grupo. Conclusão: Programa autossupervisionado requer maior disciplina dos pacientes e apenas orientar em grupo e distribuir manual podem não ser suficientes. Estratégias de acompanhamento semanal para motivação e suporte às dúvidas podem ser necessárias. (AU)

Introduction: Home-based exercises are an accessible therapeutic option for patients with Parkinson's disease who have locomotion difficulty. Physiotherapy services use lectures and manuals as a way of guiding the practice of these exercises, but they lack to evaluate what is in fact being understood by the patient. Purpose: To investigate knowledge, attitudes and practices of people with Parkinson's disease about a self-supervised home exercise program with a guidance group. Methods: This is a cross-sectional study carried out with people with mild and moderate idiopathic Parkinson's disease, in a reference program at a university hospital in northeastern Brazil. Lectures and manuals have been made available by the Program since 2012. Sociodemographic, disease, assistance and habits data were collected (general file); knowledge, attitudes and practices about physical therapy exercises in the manual (Knowledge, Attitudes and Practices Survey) and barriers associated with practice (structured questionnaire). BioEstat 5.0 software was used for descriptive statistics and association tests, p ≤ 0.05. Results: We evaluated 28 patients (63 ± 7.4 years) with an average diagnosis time of 4.5 (± 2.1) years and a higher prevalence of the HY 2 stage (71.4%). Most of them attended the Program for at least one year (85.7%), were sedentary (60.7%) and reported financial (92.8%) and locomotion (53.6%) difficulties as the main obstacles to physical therapy sessions. Adherence to physiotherapy lectures was 60.7%. The majority presented adequate knowledge (60.7%) and attitudes (96.4%), however, inadequate practices (53.6%) about a home therapy program with a group guidance. Conclusion: Self-supervised program requires greater discipline of the patients and only guiding in a group and distributing a manual may not be enough. Weekly follow-up strategies for motivation and support for questions may be needed. (AU)

MAO-B and COMT Genetic Variations Associated With Levodopa Treatment Response in Patients With Parkinson's Disease.

The most commonly used Parkinson's disease (PD) treatment is the replacement of dopamine by its levodopa precursor (l-dopa). Monoamine oxidase-B (MAO-B) and catechol-o-methyl transferase (COMT) are enzymes involved in the metabolism and regulation of dopamine availability. In our study we investigated the possible relation among selected single-nucleotide polymorphisms (SNPs) in the MAO-B (rs1799836) and COMT (rs4680) genes and the therapeutic response to levodopa (l-dopa). A total of 162 Brazilian patients from the Pro-Parkinson service of Clinics Hospital of Pernambuco diagnosed with sporadic PD and treated with levodopa were enrolled. PD patients were stratified into 2 groups according to the daily levodopa dose. MAO-B and COMT SNP genotyping was conducted by polymerase chain reaction-restriction fragment length polymorphism. After multivariate analysis, we observed a significant difference between PD groups for the following variables: sex (P = .02), longer duration of disease (P = .02), longer levodopa therapy duration (P = .01), younger onset of PD (P = .01), and use of COMT inhibitor (P = .02). We observed that patients carrying MAO-B (rs1799836) A and AA genotypes and COMT (rs4680) LL genotype suffered more frequently from levodopa-induced-dyskinesia. In addition, we found an increased risk of 2.84-fold for male individuals carrying the MAO-B G allele to be treated with higher doses of levodopa (P = .04). We concluded that before beginning PD pharmacological treatment, it is important to consider the genetic variants of the MAO-B and COMT genes and the sex, reinforcing the evidence that sexual dimorphism in the genes related to dopamine metabolism might affect PD treatment.

Individualized guidance and telephone monitoring in a self-supervised home-based physiotherapeutic program in Parkinson / Orientação individualizada e monitoramento telefônico em programa domiciliar fisioterapêutico autossupervisionado no Parkinson

Abstract Introduction: Home therapeutic exercises have been a target of interest in the treatment of the Parkinson's disease (PD). The way that the physical therapist guides and monitors these exercises can impact the success of therapy. Objective: To evaluate the effects of individualized orientation and monitoring by telephone in a self-supervised home therapeutic exercise program on signs and symptoms of PD and quality of life (QoL). Methods: Single-blind randomized clinical trials with 28 people with PD (Hoehn and Yahr 1 to 3). Patients were randomized into two groups: experimental and control. The experimental group had a meeting with individualized guidance about physiotherapy exercises present in a manual, received the manual to guide their activities at home and obtained subsequent weekly monitoring by telephone. The control group received the usual cares by the service. Both were orientated to carry out exercises three times a week during 12 weeks. Was evaluated: (1) activities of daily living (ADL) and motor examination sections of the Unified Parkinson's Disease Rating Scale (UPDRS) and QoL by the Parkinson Disease Questionnaire 39 (PDQ-39). The analysis between groups was performed by the Mann-Whitney test and intragroup through the Wilcoxon (p < 0.05). Results: Significant improvement in ADL (p= 0.001) and motor examination (p= 0.0008) of the UPDRS, PDQ-39 total (p = 0.027) and dimensions mobility (p = 0.027), emotional well-being (p= 0.021) and bodily discomfort (p = 0.027) in the experimental group compared to the control group. Conclusion: The individualized guidance and weekly monitoring by telephone in a self-supervised home therapeutic exercises program promoted positive effects on ADL, motor examination and QoL of people in early stages of PD.

Resumo Introdução: Exercícios terapêuticos domiciliares vêm sendo alvo de interesse no tratamento da doença de Parkinson (DP). A forma como o fisioterapeuta orienta e monitora estes exercícios pode impactar no sucesso da terapêutica. Objetivo: Avaliar os efeitos da orientação individualizada e do monitoramento por telefone em um programa de exercícios terapêuticos domiciliares autossupervisionados sobre os sinais e sintomas da DP e a qualidade de vida (QV). Métodos: Ensaio clínico randomizado simples-cego com 28 pessoas com DP (Hoehn e Yahr 1 a 3). Pacientes foram randomizados em dois grupos: experimental e controle. O grupo experimental teve um encontro com orientação individualizada sobre os exercícios de fisioterapia de um manual, recebeu o manual para orientar atividades em domicílio e obteve posterior monitoramento semanal por telefone. O grupo controle recebeu cuidados usuais do serviço. Ambos foram orientados a realizar exercícios três vezes por semana durante 12 semanas. Foram avaliadas: seções atividades da vida diária (AVD) e exame motor da Escala Unificada de Avaliação da Doença de Parkinson (UPDRS) e QV mediante Questionário de Doença de Parkinson 39 (PDQ-39). Foi realizada análise intergrupos (Mann-Whitney) e intragrupos (Wilcoxon) com p < 0.05. Resultados: Melhora significativa nas seções AVD (p = 0.001) e exame motor (p = 0.0008) da UPDRS, PDQ-39 total (p = 0.027) e dimensões mobilidade (p=0.027), bem-estar emocional (p = 0.021) e desconforto corporal (p=0.027) no grupo experimental quando comparado ao controle. Conclusão: A orientação individualizada e o monitoramento semanal por telefone em um programa de exercícios terapêuticos domiciliares autossupervisionados apresentaram efeitos positivos sobre AVD, exame motor e QV em estágios iniciais da DP.

Acupuncture as Adjuvant Therapy for Sleep Disorders in Parkinson's Disease.

There are few studies which attest the efficacy of acupuncture on treatment of sleep disturbs in Parkinson disease. The aimed of this randomized clinical trial was to evaluate the effects of acupuncture on sleep disturbs of 22 patients with diagnosis of idiopathic Parkinson disease (Hoehn-Yahr 1 to 3) who have assistance on the Pro-Parkinson Program of Clinical Hospital at Federal University of Pernambuco in Brazil. All participants were evaluated by Parkinson Disease Sleep Scale (PDSS) before and after 8 weeks. The experimental group was submitted to 8 sections (once a week) which had duration of 30 minutes. The control group had no intervention. The intervention was executed using the acupuncture points LR3 (Taichong), SP6 (Sanyinjiao), LI4 (Hegu), TE5 (Wai-Guan), HT7 (Shenmen), PC6 (Neiguan), LI11 (Quchi), GB20 (Fengchi). Paired analyses were obtained by Wilcoxon test and independent analyses were made according to Mann-Whitney test. This study presented a potential therapeutic benefit of acupuncture on sleep disturbs of Parkinson's disease patients. This study showed a possible therapeutic benefit through acupuncture in sleep disorders in patients with PD. However, we propose new studies related to the effects of acupuncture on the clinical symptoms and evolution of the disease.

Pain characterization in patients with Parkinson's disease / Caracterização da dor em pacientes com doença de Parkinson

BACKGROUND AND OBJECTIVES: Pain in Parkinson's disease is a very frequent complaint and may precede the diagnoses of the disease. This study aimed at evaluating pain in a group of Parkinson's disease patients from a specialized treatment center. METHODS: This is a observational study of pain in Parkinson's disease patients from the Clinicas Hospital, Federal University of Pernambuco. The convenience sample, obtained between July and August 2011, was made up of 24 individuals, being 17 males and 7 females, aged between 42 and 50 (mean=64.3) years, and 48 and 66 (mean=58.7) years, respectively. Section III of the Unified Parkinson's Disease Rating Scale, Hoehn and Yahr (HY) scale according to the stage of the disease, McGill pain questionnaire and Mini Mental State Examination were used. RESULTS: Specific body region with most frequent pain was lumbar spine (50%). Categorized regions with highest complaint percentages were: trunk (66.7%) and limbs (37.5% upper; 37.5% lower). Most patients have referred pain in a single body region, regardless of analyzing specific or categorized regions (37.5%). There has been no significant difference in proportional scores obtained by each McGill questionnaire score component. Patients with rigid-akinetic Parkinson's disease had higher number of painful body regions. The comparison among McGill indices, according to predominant symptom and according to Parkinson's disease stage (HY) scores has not shown significant differences. CONCLUSION: In our study, all Parkinson's disease patients have referred pain. Although pain is one of the most frequent non-motor symptoms, many aspects regarding Parkinson's disease-related pain need further investigation, such as which would be the best pain categorization and which methodology could better distinguish different mechanisms of different types of pain. .

JUSTIFICATIVA E OBJETIVOS: A dor na doença de Parkinson é uma queixa muito frequente, podendo preceder o diagnóstico da doença. O objetivo deste estudo foi avaliar a dor num grupo de pacientes com doença de Parkinson de um serviço de atendimento especializado. MÉTODOS: Trata-se de um estudo observacional da dor em pacientes com doença de Parkinson no Hospital das Clínicas da Universidade Federal de Pernambuco. A amostra de conveniência, obtida entre julho e agosto de 2011, foi composta por 24 sujeitos, sendo 17 do gênero masculino e 7 do gênero feminino, com idades que variaram de 42 a 50 (média=64,3) anos e 48 a 66 (média=58,7) anos, respectivamente. Utilizou-se a sessão III da Escala Unificada de Avaliação da Doença de Parkinson, a classificação segundo o estágio da doença de Hoehn e Yahr (HY), o questionário de dor McGill e o Mini-Exame do Estado Mental. RESULTADOS: A região específica do corpo com dor mais frequente foi coluna lombar (50%). As regiões categorizadas com maior percentual de queixas foram: tronco (66,7%) e membros (37,5% - superiores; 37,5% - inferiores). A maioria dos pacientes referiu dor em apenas uma região do corpo, independentemente de se analisar as regiões específicas ou categorizadas (37,5%). Não houve diferença significativa na pontuação proporcional atingida por cada componente da pontuação do questionário McGill. Pacientes com doença de Parkinson do grupo rígido-acinético apresentaram maior número de regiões do corpo com dor. A comparação entre as pontuações dos índices de McGill, segundo o sintoma predominante e segundo o estágio da doença de Parkinson (HY) não apresentou diferença significativa. CONCLUSÃO: No presente estudo, todos os pacientes com ...
