“Introduction: Chagas’ disease can lead to severe and potentially lethal damage of cardiac function. Thus, the identification of cardiac abnormalities in patients presenting the indeterminate form (IF) can be important for risk stratification. This paper aimed Citarinostat mouse to demonstrate whether IF chagasic

patients who presented wall motion abnormalities showed functional and electric disturbances compared to patients with normal echocardiogram and Doppler studies. Methods: Thirty eight patients with the IF were studied, including 26 chagasic patients with normal electrocardiographic, radiological and echocardiographic exams and 12 chagasic patients showing segmental wall motion abnormalities in the echocardiographic exam. All the patients were submitted to complete echocardiogram and Doppler study, including tissue Doppler imaging (TDI) and Holter 24h monitoring. Results: Among the variables evaluated, significant differences among the two groups were verified in relation to: the ejection fraction (p <= 0.001); left ventricular systolic dimension (p = 0.029); isovolumic contraction time, measured by TDI in the basal segments of the left ventricle (p < 0.05); and the presence of isolated (p = 0.0005) and paired ventricular extrasystoles (p = 0.003), selleck compound in the Holter monitoring. Conclusions: The indeterminate

form of Chagas’ disease can present cardiac wall motion abnormality, demonstrating

Lonafarnib in vivo functional and electric damage compared to chagasic patients with normal echocardiogram.”
“The evaluation of oral and vocal fold diadochokinesis (DDK) in individuals with voice disorders may contribute to the understanding of factors that affect the balanced vocal production. Scientific studies that make use of this assessment tool support the knowledge advance of this area, reflecting the development of more appropriate therapeutic planning. Objective: To compare the results of oral and vocal fold DDK in dysphonic women and in women without vocal disorders. Material and methods: For this study, 28 voice recordings of women from 19 to 54 years old, diagnosed with dysphonia and submitted to a voice assessment from speech pathologist and otorhinolaryngologist, were used. The control group included 30 nondysphonic women evaluated in prior research from normal adults. The analysis parameters like number and duration of emissions, as well as the regularity of the repetition of syllables “pa”, “ta”, “ka” and the vowels “a” and “i,” were provided by the Advanced Motor Speech Profile program (MSP) Model-5141, version-2.5.2 (KayPentax). The DDK sequence “pataka” was analyzed quantitatively through the Sound Forge 7.0 program, as well as manually with the audio-visual help of sound waves.
