Estudio preliminar del estado periodontal de pacientes con infarto cerebral isquémico / Preliminary study of the periodontal status of patients with ischemic stroke

Introducción: se reporta a la periodontitis como factor de riesgo de las siguientes enfermedades: diabetes mellitus, partos pretérminos, neonatos bajo peso, infecciones respiratorias, entre otras. Se atribuye destacada importancia al vínculo con enfermedades derivadas de la ateroesclerosis como infartos cardíacos y cerebrales. Objetivo: determinar posible asociación entre enfermedad periodontal e infarto cerebral isquémico aterotrobótico. Materiales y métodos: entre octubre 2015 y marzo del 2016, se realizó un estudio transversal observacional, de casos y controles, en los Hospitales "Freyre de Andrade" y "Dr. Luis Díaz Soto". Se registraron factores de riesgo para el infarto cerebral isquémico aterotrobótico y el estado periodontal, según el indice periodontal de Russell. El grupo control se homologó respecto a los casos en una proporción de 1X1, según edad, sexo, color de la piel y al menos 1 factor de riesgo reconocido del infarto cerebral. Se respetaron principios y normativas bioéticas para investigaciones biomédicas. Se emplearon medidas de resumen para datos cualitativos (frecuencias absolutas y porcentajes). Resultados: fueron estudiados 44 pacientes, 22 casos y 22 controles, mayoritariamente de 71 o más años, masculinos y blancos. Predominaron los pacientes con enfermedad periodontal sobre los sanos periodontalmente, 88,6 % y 11,4 %; respectivamente. La periodontitis fue el estado que prevaleció. La hipertensión arterial fue el factor asociado al infarto cerebral isquémico aterotrobótico que se presentó con mayor frecuencia, 61,4 %. Conclusiones: en todos los grupos la enfermedad periodontal predominó respecto al resto de factores de riesgo explorados del infarto cerebral isquémico, lo que pudiera sugerir asociación entre ambas enfermedades (AU).

Introduction: periodontitis is reported as a risk factor for diseases such as diabetes mellitus, preterm births, low weight neonates, and respiratory infections among others. The relationship between periodontal disease and diseases caused by atherosclerosis such as ischemic stroke and myocardial infarction has been emphasized. Objective: to determine the possible association between periodontal disease and atherothrombotic ischemic cerebral infarction (AICI). Materials and Methods: in the period from October 2015 to March 2016, an observational, case-control, cross-sectional study was carried out at the Hospitals "Freyre de Andrade" and " Dr. Luis Díaz Soto". Risk factors were recorded for AICI and the periodontal state, according to the revised Periodontal Russell's Index. The control group was homologated for cases at a ratio of 1x1, based on age, sex, skin color and at least 1 recognized AICI risk factor. Bioethical principles and regulations for biomedical research were respected. Summary measures were used for qualitative data (absolute frequencies and percentages). Results: 44 patients were studied, 22 cases and 22 controls, most of them aged 71 or more years, male and white. Patients with periodontal disease predominated over the periodontally healthy ones (88, 6 % y 11, 4 % respectively). Periodontitis was the most prevalent condition. High blood pressure was the most frequent factor associated to AICI, 61.4 %. Conclusions: in all groups, periodontal disease prevailed over the rest of the explored AICI risk factors, what may suggest an association between both diseases (AU).

La enfermedad periodontal, ¿un factor de riesgo más para el infarto cerebral isquémico aterotrombótico? / Periodontal disease, is it one more risk factor for atherothrombotic ischemic stroke?

De forma compactada se explica la relación biológicamente plausible que existe entre la aparición de accidentes cerebrovasculares, particularmente de infarto cerebral isquémico aterotrombótico y la precedencia de enfermedad periodontal inmuno-inflamatoria crónica. Se sugiere la necesidad de estudios que vinculen ambas entidades para conciliar los resultados de las investigaciones internacionales con las realizadas en nuestro medio. Se propone el análisis del estado periodontal en los pacientes pertenecientes a grupos de riesgo o víctimas de enfermedades cerebrovasculares. La consideración de la enfermedad periodontal inmuno-inflamatoria crónica como un factor de riesgo más para el infarto cerebral isquémico aterotrombótico, debe pasar de una interrogante a una estrategia(AU)

The biologically plausible relation existing between the occurrence of cerebrovascular accidents, particularly of atherothrombotic ischemic stroke, and the presence of chronic immunoinflammatory periodontal disease is explained in a compacted way. The need for studies linking both entities is suggested for conciliating the results of the international researches with those carried out in our environment. The analysis of the periodontal state in patients from risk groups of victims on cerebrovascular disease is proposed. Considering the chronic immunoinflammatory periodontal disease as a risk factor for atherothrombotic ischemic stroke should pass from a question to a strategy(AU)

Predictive factors for spasticity among ischemic stroke patients / Fatores preditivos para espasticidade após acidente vascular cerebral

Spasticity is a determining for functional loss following ischemic stroke. OBJECTIVE: To detect possible predictive factors for its occurrence. METHOD: Demographic, clinical and tomographic data on 146 stroke patients were analyzed. RESULTS: Spasticity was noted more frequently among patients who underwent physiotherapy (p<0.0001; OR=19.4; 95 percent CI: 4.4-84.5), those who underwent such treatment for long periods (p=0.028; OR=4.80; 95 percent CI: 1.1-8.3) and those with manual work (p=0.041; OR=2.2; 95 percent CI: 1.02-4.6), lower income (p=0.038), pain complaints (p<0.0001; OR=107.0; 95 percent CI: 13.5-847.3), appearance of pain at the same time as spasticity (p<0.0001), previous vascular disease (p=0.001; OR=4.2; 95 percent CI: 1.7-10.3), muscle weakness (p<0.0001; OR=91.9; 95 percent CI: 12.0-699.4), extensive lesions as seen on tomography (p=0.01) and lesions affecting more than one cerebral lobe (p=0.018). Manual work had a relative risk of 2.9; previous stroke 3.9, and extensive lesion 3.6. CONCLUSION: Spasticity affected 25 percent of the patients, and was associated with: manual work, previous stroke, extensive lesions, decrease in individual income, underwent physiotherapy, underwent physiotherapy for longer period, pain complaints, the pain started simultaneously with the spasticity, presented changes in strength.

A espasticidade é fator determinante para perda funcional após o acidente vascular cerebral isquêmico (AVCI). OBJETIVO: Detectar possíveis fatores preditivos para a ocorrência da espasticidade. MÉTODO: Foram analisados dados demográficos, clínicos e tomográficos de 146 pacientes pós-AVCI. RESULTADOS: Na análise univariada a espasticidade foi notada com maior freqüência em pacientes que realizaram fisioterapia (p<0,0001; OR=19,4; 95 por cento CI: 4,4-84,5), com maior tempo de duração desse tratamento (p=0,028; OR=4,80; 95 por cento CI: 1,1-8,3) e que realizavam trabalho braçal (p=0,041; OR=2,2; 95 por cento CI: 1,02-4,6), renda menor (p=0,038), referência de dor (p<0,0001; OR=107,0; 95 por cento CI: 13,5-847,3) e seu aparecimento simultâneo à espasticidade (p<0,0001), acidente vascular cerebral (AVC) pregresso (p=0,001; OR=4,2; 95 por cento CI: 1,7-10,3), fraqueza muscular (p<0,0001; OR=91,9; 95 por cento CI: 12,0-699,4), lesão tomográfica extensa (p=0,01) e lesão afetando mais de um lobo cerebral (p=0,018). Na análise de regressão multivariada a atividade braçal apresentou risco relativo de 2,9; acidente vascular cerebral prévio com risco relativo de 3,9 e lesão tomográfica extensa risco relativo de 3,6. CONCLUSÃO: A espasticidade afetou um quarto da população estudada e esteve associada ao trabalho braçal, AVC pregresso, lesões tomográficas extensas, diminuição da renda individual, realização de fisioterapia, realização de fisioterapia por um período maior, presença de dor, surgimento da dor simultânea à espasticidade e alteração da força.
