CONTEXT Studies have described the correlation between platelet count and the stages of fibrosis in chronic viral hepatitis, but few publications have studied this correlation in Schistosomiasis mansoni. OBJECTIVES Therefore, this study aimed to correlate platelet count with both the periportal fibrosis pattern and spleen diameter evaluated by ultrasound exam in patients with Schistosomiasis ...

Let s ? 3 $s \geqslant 3$ be a natural number, let ? ( x ) $\psi (x)$ polynomial with real coefficients and degree d 2 $d 2$ , A $A$ some large, non-empty, finite subset of numbers. We use E $E_{s,2}(A)$ to denote the number solutions system equations ? i = 1 ? + 0 \begin{equation*}\hskip2.5pc \sum _{i=1}^{s} (\psi (x_i) - \psi (x_{i+s}) )= (x_i x_{i+s} 0, \end{equation*} where ? $x_i \in A$ fo...

BACKGROUND Early elective surgery may prevent rupture of abdominal aortic aneurysms, but mortality is 5-6%. The risk of rupture seems to be low for aneurysms smaller than 5 cm. We investigated whether prophylactic open surgery decreased long-term mortality risks for small aneurysms. METHODS We randomly assigned 1090 patients aged 60-76 years, with symptomless abdominal aortic aneurysms 4.0-5....

OBJECTIVE To assess the efficacy of an office-based, family physician–administered ultrasound examination to screen for abdominal aortic aneurysm (AAA). DESIGN A prospective observational study. Consecutive patients were approached by nonphysician staff. SETTING Rural family physician offices in Grand Forks and Revelstoke, BC. PARTICIPANTS The Canadian Society for Vascular Surgery screeni...

HYPOTHESIS Small infrarenal abdominal aortic aneurysms have a more favorable clinical and morphologic outcome compared with medium and large abdominal aortic aneurysms following endovascular aneurysm repair(EVAR). DESIGN A prospective clinical series of 206 patients undergoing elective EVAR between 1996 and 2001. SETTING A tertiary care academic health center. PATIENTS Patients were group...

OBJECTIVE Untreated abdominal aortic aneurysms (AAAs) enlarge at a mean rate of 3.9 mm/y with great individual variability. We sought to determine the effect of endovascular repair on the rate of change in aneurysm size. METHODS There were 110 patients who underwent endovascular AAA repair at Stanford University Medical Center and who were followed up for 1 to 30 months (mean, 10 months) with...
