RESUMO
OBJECTIVE: To investigate the reliability (test-retest and inter-rater) and criterion-related validity of the modified sphygmomanometer test (MST) for the assessment of upper limb muscle strength in subjects with chronic stroke, and to determine whether the results are affected by the number of trials. PATIENTS AND METHODS: The strength of 11 upper limb muscle groups of 57 subjects with stroke was bilaterally assessed with portable dynamometers and the MST (measured in mmHg). To investigate whether the number of trials would affect the results, 1-way analysis of variance was applied. For the test-retest/inter-rater reliabilities and criterion-related validity of the MST, intra-class correlation coefficients (ICCs), Pearson's correlation coefficients, and coefficients of determination were calculated. RESULTS: Different numbers of trials provided similar values for all assessed muscles (0.01 ≤ F ≤ 0.18; 0.83 ≤ p ≤ 0.99) with adequate test-retest (0.83 ≤ ICC ≤ 0.97; p < 0.0001) and inter-rater reliabilities (0.79 ≤ ICC ≤ 0.97; p < 0.0001) and validity (0.61 ≤ r ≤ 0.95; p < 0.0001). The values obtained with the MST were good predictors of those obtained with portable dynamometers (0.60 ≤ r2 ≤ 0.86), except for pinch strength (0.39 ≤ r2 ≤ 0.54). CONCLUSION: The MST showed adequate measurement properties for the assessment of the strength of the upper limb muscles of subjects with chronic stroke. After familiarization a single trial provided adequate strength values.

We compared intra-arterial to auscultation blood pressure values using correct (CCW) or standard (SCW) cuff widths. Intra-arterial values were obtained from the radial artery using a digital monitor. Measurements were simultaneously made by two observers: one recorded intra-arterial values, while the other registered values by auscultation (brachial artery). Systolic intra-arterial pressure (mmHg) values were 125.04 vs. 119.75 (CCW), and 124.84 vs 116.39 (SCW). Diastolic pressure values were 68.72 vs. 73.26 (CCW), and 68.63 vs. 70.56 (SCW). Auscultation underestimated systolic pressure, particularly when SCW was used, whereas it overestimated diastolic pressure, when CCW was used. Auscultation using CCW yielded higher agreement of systolic pressure values and lower agreement of diastolic pressure values as compared to intra-arterial blood pressure measurements.

Objetivo: Tem-se por objetivo avaliar possíveis alteraçöes cardiovasculares, tais como as da pressäo arterial e freqüência cardíaca, produzidas pela instilaçäo tópica de fenilefrina 10 por cento.Local: Serviço de Oftalmologia do Hospital Regional de Säo José -Homero de Miranda Gomes, Säo José, SC.Métodos: Sessenta pacientes adultos atendidos na emergência oftalmológica do Hospital Regional Säo José com indicaçäo de exame sob midríase foram divididos em dois grupos de 30, aleatoriamente.No primeiro foi instilada 1 gota de fenilefrina 10 por cento em cada olho e no segundo, utilizado como controle, 1 gota de tropicamida (mydryacil) também em ambos os olhos.Todos os pacientes em estudo tiveram sua freqüênia cardíaca e pressäo arterial monitoradas em 5 tempos distintos (pré, 1 minuto após, 5 minutos após e 30 minutos após a instalaçäo da droga) com auxílio de um esfigmomanômetro eletrônico (marca Omron, USA).Resultados: Näo houve diferença entre a idade, sexo e raça nos grupos estudados.a freqüência cardíaca média inicial foi de 79, 65(ñ11, 51) batimentos por minuto, sem diferença entre os grupos, näo sendo observada alteraçäo da freqüencia durante o acompanhamento(P>0.05).A pressäo diastólica média inicial foi de 92, 16(ñ17, 70)mmHg näo existindo diferença entre os grupos, sendo observada uma diminuiçäo significativa desta, nos dois grupos em estudo, a partir do 15º minuto(P<0.05).Conclusäo: Observou-se que a instalaçäo de uma gota de fenilefrina a 10 por cento em cada olho näo produziu alteraçöes na freqüência cardíaca ou pressäo arterial sistêmica em pacientes adultos.

Peripheral occlusive arterial disease occurs with a greater frequency in the diabetic population than in the general population. It can have debilitating effects and so early detection and intervention are important. The aim of this study was to investigate the prevalence of peripheral occlusive arterial disease (POAD) among a sample of diabetic patients attending the out-patient clinic at the University Hospital of the West Indies (UHWI), Mona. A sphygmomanometer was used to measure arm and ankle blood pressures in 80 diabetic patients, and the ankle-brachial systolic pressure index (ABI) was determined. The presence or absence of peripheral pulses was detected with the Multi-dopplex (model 1). POAD was defined by the absence of one or more peripheral pulses and/or an ABI < 0.09. Of the 80 diabetic patients examined, 18 (22.5 percent) were found to have POAD. Seventy-eight percent of diabetics with POAD had the disease in both legs. Intermittent claudication was diagnosed in 27.7 percent of patients with POAD. A significantly larger proportion of diabetics with POAD were hypertensive and/or neuropathic (p < 0.05). The results suggest that serious attention should be given to the quantitative screening for POAD in the diabetic patients attending the clinic at the UHWI (AU)
