Paciente bruxómano e as suas opções terapêuticas

O bruxismo caracteriza-se por um ato involuntário de apertar e/ou ranger os dentes sendo este hábito um fator de risco que pode comprometer a função do sistema estomatognático com várias sequelas associadas (dor dentária e muscular, desgaste dentário, etc.). Esta pesquisa bibliográfica pretende rever as possibilidades terapêuticas que se podem apresentar como soluções no controlo desta parafunção. A bibliografia ainda é inconclusiva sobre qual o melhor tratamento a seguir sugerindo uma abordagem multidisciplinar, tendo em conta a etiologia e a sintomatologia para a definição de um plano de tratamento mais completo e adequado. Têm surgido cada vez mais alternativas terapêuticas e cada uma delas, ao longo do tempo, tem desenvolvido novas metodologias mais eficazes no tratamento do bruxismo.

Interatrial block and atrial arrhythmias in centenarians: Prevalence, associations, and clinical implications

Data are lacking on the characteristics of atrial activity in centenarians, including interatrial block (IAB). The aim of this study was to describe the prevalence of IAB and auricular arrhythmias in subjects older than 100 years and to elucidate their clinical implications. We studied 80 centenarians (mean age 101.4 ± 1.5 years; 21 men) with follow-ups of 6–34 months. Of these 80 centenarians, 71 subjects (88.8%) underwent echocardiography. The control group comprised 269 septuagenarians. A total of 23 subjects (28.8%) had normal P wave, 16 (20%) had partial IAB, 21 (26%) had advanced IAB, and 20 (25.0%) had atrial fibrillation/flutter. The IAB groups exhibited premature atrial beats more frequently than did the normal P wave group (35.1% vs 17.4%; P < .001); also, other measurements in the IAB groups frequently fell between values observed in the normal P wave and the atrial fibrillation/flutter groups. These measurements included sex preponderance, mental status and dementia, perceived health status, significant mitral regurgitation, and mortality. The IAB group had a higher previous stroke rate (24.3%) than did other groups. Compared with septuagenarians, centenarians less frequently presented a normal P wave (28.8% vs 53.5%) and more frequently presented advanced IAB (26.3% vs 8.2%), atrial fibrillation/flutter (25.0% vs 10.0%), and premature atrial beats (28.3 vs 7.0%) (P < .01). Relatively few centenarians (<30%) had a normal P wave, and nearly half had IAB. Our data suggested that IAB, particularly advanced IAB, is a pre–atrial fibrillation condition associated with premature atrial beats. Atrial arrhythmias and IAB occurred more frequently in centenarians than in septuagenarians.

Oral anticoagulation in octogenarians with atrial fibrillation

Vitamin K antagonists (VKAs) are still largely employed, even in nonvalvular atrial fibrillation (AF). Our aim was to study the clinical profile of octogenarians treated with oral anticoagulation and to study the effect of age on the quality of VKAs anticoagulation. Data are from a prospective national registry in an adult Spanish population of nonvalvular AF. We included 1637 patients who had been receiving VKAs for at least 6 months before enrolment. Mean age was 73.8 ± 9.4 years. Patients aged > 80 years (N = 429) had a high risk profile with higher risk of stroke and bleeding than younger patients; CHA2DS2-VASc (Cardiac failure, Hypertension, Age > 74, Diabetes, Stroke, Vascular disease, Age 65–74 years, and Sex category) 4.5 ± 1.3 vs. 3.5 ± 1.6, p < 0.001, HAS-BLED (Hypertension, Abnormal renal/liver function, Stroke, Bleeding history or predisposition, Labile international normalized ratio, Elderly (> 64 years), Drugs/alcohol concomitantly) 2.4 ± 0.9 vs. 1.9 ± 1.1, p < 0.001. Creatinine clearance was lower in octogenarians than in younger patients (54.3 ± 16.1 ml/min vs. 69.5 ± 23.7 ml/min, p < 0.001) and severe renal disease with creatinine clearance < 30 ml/min was more frequent in octogenarians (5.2% vs. 2.2%, p < 0.001). In patients treated with VKAs (N = 1637), the international normalized ratio values of the 6 months previous to enrollment were similar in all age quartiles, as was the time in the therapeutic range. In this large registry octogenarians with nonvalvular AF had high risk of stroke and bleeding and frequent renal disease. VKAs anticoagulation quality was similar in octogenarians and in younger patients.
