Abstract The relationship between atrial fibrillation and human immunodeficiency virus (HIV) infection was evaluated. Electro-echocardiographic methods can be used to predict the development of ...atrial fibrillation (AF). In this study, we aimed to investigate the atrial electromechanical delay (AEMD) parameters of HIV (+) patients. Forty-two HIV (+) patients and 40 HIV (−) healthy volunteers were prospectively enrolled in this study. The electromechanical properties of the subjects’ atria were evaluated with tissue Doppler imaging. The left-AEMD, right-AEMD and inter-AEMD were increased in the HIV (+) patients relative to the controls (p = 0.003, p < 0.001, and p < 0.001, respectively). The CD4 count was inversely correlated with the inter-AEMD (r = −0.428, p < 0.001). The CD4 count was an independent predictor of the inter-AEMD ( β = 0.523, p = 0.007). Our study demonstrated that both the inter- and intra-atrial electromechanical delays were prolonged in the patients with HIV. This non-invasive and simple technique may provide significant contributions to the assessment of the risk of atrial arrhythmia in patients with HIV.

The purpose of this paper is to draw attention to atypical presentations of brucellosis. A prospective study identified 240 consecutive patients with brucellosis admitted to our department between ...December 1999 and July 2002. From these cases we present 11 patients with unusual clinical presentations. Neurobrucellosis, peritonitis, pericarditis, pancytopenia, and uveitis were diagnosed in 2 patients each and 1 presented with epididymo-orchitis.

Abstract Human Immunodeficiency Virus (HIV) infection and AIDS are known to cause cardiovascular diseases such as premature coronary artery disease, cardiomyopathy, and arrhythmias. Recently, Tp–e ...interval and Tp–e/QT ratio has been shown as a novel marker of ventricular repolarization. We aimed to evaluate the ventricular repolarization using Tp–e interval and Tp–e/QT ratio in patients with Human Immunodeficiency Virus (HIV) infection. Totally 48 patients with HIV and 60 control subjects were enrolled to the study. Tp–e interval, Tp–e/QT and Tp–e/QTc ratio were measured from the 12-lead electrocardiogram. Tp–e interval, Tp–e/QT ratio and Tp–e/QTc ratio were significantly higher in patients with HIV than control subjects (all p < 0.01). In correlation analysis, there were positive correlation between Tp–e interval and disease duration (r = 0.298, p = 0.048). and inverse correlation between Tp–e interval and CD4 count(r = −0.303, p = 0.036). Our study showed that Tp–e interval, Tp–e/QT and Tp–e/QTc ratios were increased in patients with HIV than control subjects.

A miniaturized and electromagnetically driven FR4 based moving platform is developed for Fourier Transform spectrometer applications. Both Michelson interferometer and Lamellar Grating interferometer ...configurations are demonstrated. plusmn500 mum translational motion (corresponding to 5 cm -1 spectral resolution) is demonstrated with the moving platform. Two methods are proposed and partially demonstrated for pure translational motion: (1) integrated control system using a quad photo detector feedback and (2) corner cube retroreflector. The fundamental advantages and the limits of the lamellar grating interferometers are also discussed.
