The aim of the study was to evaluate the association between salivary anti-Porphyromonas gingivalis IgA antibodies and the leprosy reaction. The levels of salivary anti - P. gingivalis IgA antibodies, together with salivary flow and pH were measured in individuals diagnosed with leprosy and associated with the development of the leprosy reaction.

Caseous lymphadenitis (CL) is a chronic infectious disease that affects sheep and goats. Many serological tests have been developed to detect the disease; one of the most widely used is the enzyme-linked immunosorbent assay (ELISA), due to its advantages, which include acceptable cost-effectiveness, applicability, sensitivity and specificity. ELISA formulations using recombinant proteins can exhibit significant sensitivity and specificity when using a single purified antigen.

Methods: a longitudinal study, conducted from November 2010 to September 2011, with implementation of the instruments HAQ II (health assessment questionnaire) and SF-36 (medical outcomes short-from health survey). Barlett test, Anova, Friedman and paired t-test were performed for multiple extracts.
Takayasu's arteritis (TA) is a large vessel vasculitis of unknown aetiology characterised by involvement of the aorta and its major branches. Tuberculous arteritis of the aorta is an uncommon condition usually secondary to the dissemination of Mycobacterium tuberculosis infection from the mediastinum and/or lung to the adjacent aorta; this may mimic TA. We report a case of a 23-year-old woman with cutaneous granulomatous vasculitis and saccular aneurysmal dilation of the aorta and large vessels, and highlight the findings shared by TA and tuberculous arteritis.

Medical management is necessary to slow progression of the disease and control of hypoglycemic symptoms when cure by surgical treatment is not possible. Multimodal treatment, in these cases, has been used with variable clinical response.

Methods: 21 patients (23 vessels) were examined with DSCT, IVUS and invasive coronary angiography. Coronary minimal luminal diameter (MLD) and area (MLA) were measured in cross-sectional multi-planar reformatted images perpendicular to the vessel long-axis.
Epicardial fat accumulation may have important clinical consequences, yet little is known regarding this depot in HIV patients. We compared epicardial fat volume in 78 HIV-infected men and 32 HIV-negative controls. Epicardial fat volume was higher in HIV-infected patients than that in controls (P = 0.

The tumor was visualized with electrocardiographic-gated dual-source computed tomography, showing a low-density, lobulated mass invading the inferior vena cava and prolapsing through the tricuspid valve during diastole. Cardiac computed tomography is useful in assessing the extension and hemodynamic effect of intracardiac masses.

Materials And Methods: Institutional review board approval and informed patient consent were obtained before patient enrollment in the study. The study was HIPAA compliant.
Objective: The degree of subclinical coronary atherosclerosis in HIV-infected patients is unknown. We investigated the degree of subclinical atherosclerosis and the relationship of traditional and nontraditional risk factors to early atherosclerotic disease using coronary computed tomography angiography.
Design And Methods: Seventy-eight HIV-infected men (age 46.
Introduction: We have recently described a technique for assessing myocardial perfusion using adenosine-mediated stress imaging (CTP) with dual source computed tomography. SPECT myocardial perfusion imaging (SPECT-MPI) is a widely utilized and extensively validated method for assessing myocardial perfusion. The aim of this study was to determine the level of agreement between CTP and SPECT-MPI at rest and under stress on a per-segment, per-vessel, and per-patient basis.

Computed tomography (CT) coronary angiography is an emerging technology allowing detection of both obstructive and nonobstructive CAD adding information to clinical risk stratification. The aim of this study was to evaluate the association between CAD and adiposity measurements assessed clinically and by CT.
View Article and Find Full Text PDFObjectives: This study sought to determine the feasibility of performing a comprehensive cardiac computed tomographic (CT) examination incorporating stress and rest myocardial perfusion imaging together with coronary computed tomography angiography (CTA).
Background: Although cardiac CT can identify coronary stenosis, very little data exist on the ability to detect stress-induced myocardial perfusion defects in humans.
Methods: Thirty-four patients who had a nuclear stress test and invasive angiography were included in the study.
This study aims at evaluating the application of magnetic resonance spectroscopy (MRS) in the differential diagnosis of brain tumors and inflammatory brain lesions. The examinations of 81 individuals, who performed brain MRS and were retrospectively analyzed. The patients with ages between 10 and 80 years old, were divided into two groups.

This grafting in turn has led to an increased use of other arterial conduits, of which the radial artery (RA) is most popular. Whether RA grafting can be used in the emergency patient is controversial.

Method: Nine children with neurologic symptoms and sudden increase of the arterial pressure were studied by brain MRI.
