Article: Spontaneous Echo Contrast in Purulent Pericardial Effusion due to Non-Gas-Forming Organisms.
[show abstract] [hide abstract]
ABSTRACT: We present the case of a 55-year-old man who developed massive pericardial effusion with tamponade within a 5-day period. During transthoracic two-dimensional echocardiographic examination, spontaneous echo contrast was visualized in pericardial effusion. A diagnosis of polymicrobial pyopericarditis was made when urgent pericardiocentesis revealed a significantly foul odor and purulent fluid that grew a culture of aerobes. After surgical drainage and appropriate antimicrobial therapy, this patient's pyopericarditis resolved. It was suggested that spontaneous echo contrast in pericardial effusion could be induced by non-gas-forming pyogenic cells.Echocardiography 08/1998; 15(5):489-492. · 1.24 Impact Factor -
Article: Predictors of outcome after open repair of ruptured abdominal aortic aneurysms.
[show abstract] [hide abstract]
ABSTRACT: To determine predictors associated with early hospital death, 30-day mortality, and long-term survival after open surgical treatment of ruptured abdominal aortic aneurysms (RAAAs). A retrospective chart review of 127 consecutive patients who received open surgical treatment of a RAAA at Chang Gung Memorial Hospital, Taiwan, from February 1994 to May 2007. Data recorded included patient characteristics, medical history, perioperative variables, and outcomes. There were 104 men and 23 women with a mean age of 70 ∓ 12 years in the analysis. Patients with RAAAs were classified into two groups; 100 (78.7%) patients were classified as group I (hemodynamically stable), and 27 (21.3%) patients were classified as group II (hemodynamically unstable at arrival). The 30-day mortality was 22% for group I and 74.1% for group II. Multivariate analysis identified age > 75 years old (odds ratio [OR], 0.083; 95% confidence interval [CI] 0.02-0.36), hemodynamically unstable state (OR, 0.081; 95% CI 0.016-0.4), blood transfusion > 5 L (OR, 0.14; 95% CI 0.038-0.54), intraperitoneal rupture (OR, 7.2; 95% CI 1.4-36), urine output < 0.5 mL/kg/min (OR, 22; 95% CI 4.6-110), and suprarenal cross-clamping (OR, 0.083; 95% CI 0.019-0.36) as incremental risk factors for 30-day mortality. Significant predictors of mortality in patients with RAAAs include hemodynamically unstable state, age > 75 years old, intraperitoneal rupture, low intraoperative urine output, and suprarenal cross-clamping.Chang Gung medical journal 34(5):520-7.
