ABSTRACT
Background
There is little information available on stroke epidemiology in the northeast of Brazil.
Objective
Our objective was to investigate the prevalence of the stroke subtypes, ...prevalence of cerebrovascular risk factors and patterns of management in a public neurovascular outpatient referral service, in Alagoas.
Methods
Data were prospectively collected from consecutive patients with stroke who were treated in a specialized neurovascular clinic between November 2016 and June 2018. Recurrence was evaluated by telephone 12 months after patients had been included in the study.
Results
We evaluated 190 patients (mean age, 60.22 ( 13.29 years; 60.5% males). Ischemic stroke was the most frequent subtype (85.2%). Sedentary lifestyle was the most common risk factor (71.6%), followed by hypertension (62.6%) and stroke family history (41.1%). Only 21.5% of the patients were transported by ambulance to the hospital, and 42.6% received medical support in hospital units or emergency units with no imaging support. The median NIHSS was 2.5 (IQR, 1-5) and mRS was 2 (IQR, 1-3). We found a high rate of undetermined stroke (35.8%), and few patients completed the etiological investigation. One year after inclusion in the study, 12 patients (6.3%) had died and 14 (7.3%) had had another stroke.
Conclusions
The prevalence of cerebrovascular risk factors and clinical presentation were similar to what had been seen in previous series. A notable number of patients received medical support in institutions with no imaging equipment. The high number of cases of undetermined stroke etiology shows the difficulty in accessing healthcare services in Alagoas.
To determine the central tendency measures and variability of vestibular evoked myogenic potential (VEMP) with regard to the latency and wave amplitude when potentials are captured from the flexor ...muscles of the forearm.
Ten adult volunteers with normal hearing underwent examination of their forearm flexor muscles (right and left sides; 20 samples in total) for VEMP acquisition. To this end, 200 tone burst stimuli at a 500 Hz frequency and 95 dBnHL intensity were promediated.
No statistical differences were observed in VEMP responses acquired from the right and left forearm flexor muscles concerning P34 and N44 latencies (p=0.32 and 0.90, respectively). The mean latency obtained for the P34 wave component was 34.9 ms (±2.6), with a lower limit equal to 29.3 and an upper limit equal to 40.4 ms. The average latency of the N44 wave component was 43.6 ms (±2.1), with a lower limit of 39.1 ms and an upper limit of 48.1 ms. The results were consistent and had low variability, and showed an average asymmetry index of 15.4 (±10.7). These findings indicate that potentials may be investigated in different age groups and in specific clinical populations, such as pathologies that may alter the neuronal transmission of the inferior vestibular pathway, especially when a longer portion is observed.
VEMP recording from forearm flexors is both feasible and stable, with latency reference ranges between 29.3 and 40.4 ms for P34, and 39.1 and 48.1 ms for N44.
...the higher prevalence of tympanic foramen found in the Northeast among other studies carried out in Brazil can be attributed to specific dietary habits in the region that could induce the later ...foramen occlusion. ...the existence of this foramen constitutes a route for the spread of infections, which can occur both from temporo-mandibular joint to external acoustic meatus and vice versa (Silva and Collins, 2012; Tozoglu et al., 2012). ...it is important to observe the presence of TF before performing orthognathic procedures on the temporo-mandibular joint. Laterality was recorded and the longitudinal and transverse diameter of the TF were measured with the aid of a digital caliper with an accuracy of 0.01 mm. Data analysis was performed using SPSS statistical software (Version 20.0, SPSS Inc., Chicago, IL). The Northeast has a food with dense foods, which are offered in the first years of the child's life. ...the tympanic part of the temporal bone, which continues to grow even after birth, is influenced by the pressure caused by chewing and swallowing (Akcam et al., 2011; Lee and Park, 2018) and, therefore, TF occlusion tends to occur later in life (Afghari et al., 2016).
Objetivo: Analisar as características e incidência do trauma vesical durante cinco anos em um hospital geral do estado de Alagoas. Métodos: Estudo quantitativo, analítico, observacional e ...transversal, foram utilizados métodos de estatística descritiva para análise das variáveis. Resultados: Foram encontradas lesões vesicais em 63 pacientes, obteve-se análise dos prontuários nos anos de 2010 a 2015. Média de idade de 26,2 anos, com extremos entre 15 e 56 e desvio padrão de 9,85 (intervalo de confiança de 95%). A maioria era (76,2%) do sexo masculino. O trauma penetrante foi responsável por 65,07% dos casos, sendo em sua maioria (97,56%) decorrente de lesão por arma de fogo. O método diagnóstico foi predominantemente intraoperatório (82,53%). As lesões mais frequentes foram de cúpula vesical (23,8%), parede anterior e posterior (11,11%). O tratamento de escolha foi cirúrgico em 88,89% e conservador nos demais. A taxa de mortalidade global no trauma vesical foi de 7,93% a sobrevida média de 88,87%. Conclusão: Os dados encontrados são, em sua grande parte, condizentes com a literatura mundial para o trauma vesical, diferindo quanto a etiologia, método diagnóstico e a terapêutica adotada. Tais distinções, podem ser justificadas pelas características locais e do hospital estudado.
