In a prospective design, demographic data, etiology, mean hospital admission time, clinical, radiological, biochemical findings, treatment modalities, mortality and morbidity were recorded. Endocrine insufficiency was investigated with oral glucose tolerance test. The relations between these parameters, scoring systems （Ranson, Imrie and APACHE Ⅱ） and patients＇ outcome were determined by using invariable tests and the receiver operating characteristics curve.RESULTS： One hundred patients were men and 99 were women; the mean age was 55 years. Biliary pancreatitis was the most common form, followed by idiopathic pancreatitis （53% and 26%, respectively）. Sixty-three patients had severe pancreatitis and 136 had mild disease. Respiratory rate 〉 20/min, pulse rate 〉 90min, increased C-reactive protein （CRP）, lactate dehydrogenase （LDH） and aspartate aminotransferase （AST） levels, organ necrosis 〉 30% on computed tornography （CT） and leukocytosis were associated with severe disease. The rate of glucose intolerance, morbidity and mortality were 24.1%, 24.8% and 13.6%, respectively. CRP 〉 142 mg/L, BUN 〉 22 mg/dL, LDH 〉 667 U/L, base excess 〉 -5, CT severity index 〉 3 and APACHE score 〉 8 were related to morbidity and mortality.CONCLUSION： APACHE Ⅱ score, LDH, base excess and CT severity index have prognostic value and CRP is a reliable marker for predicting both mortality and morbidity.展开更多

We sought to determine whether recombinant activated factor VII (rFVIIa) can red uce hematoma growth after intracerebral hemorrhage. METHODS: We randomly assigne d 399 patients with intracerebral hemorrhage diagnosed by CT within three hours after onset to receive placebo (96 patients) or 40 μg of rFVIIa per kilogram of body weight (108 patients), 80 μg per kilogram (92 patients), or 160 μg per k ilogram (103 patients) within one hour after the baseline scan. The primary outc ome measure was the percent change in the volume of the intracerebral hemorrhage at 24 hours. Clinical outcomes were assessed at 90 days. RESULTS: Hematoma volu me increased more in the placebo group than in the rFVIIa groups. The mean incre ase was 29 percent in the placebo group, as compared with 16 percent, 14 percent , and 11 percent in the groups given 40 μg, 80 μg, and 160 μg of rFVIIa per k ilogram, respectively (P=0.01 for the comparison of the three rFVIIa groups with the placebo group). Growth in the volume of intracerebral hemorrhage was reduce d by 3.3 ml, 4.5 ml, and 5.8 ml in the three treatment groups, as compared with that in the placebo group (P=0.01). Sixty-nine percent of placebo-treated pati ents died or were severely disabled (as defined by a modified Rankin Scale score of 4 to 6), as compared with 55 percent, 49 percent, and 54 percent of the pati ents who were given 40, 80, and 160 μg of rFVIIa, respectively (P=0.004 for the comparison of the three rFVIIa groups with the placebo group). Mortality at 90 days was 29 percent for patients who received placebo, as compared with 18 perce nt in the three rFVIIa groups combined (P=0.02).

HPVG has been reported with increasing frequency in medical literature and usually accompanies severe or lethal conditions. The diagnosis of HPVG is usually made by plain abdominal radiography, sonography, color Doppler flow imaging or computed tomography (CT) scan. Currently, the increased use of CT scan and ultrasound in the inpatient setting allows early and highly sensitive detection of such severe illnesses and also the recognition of an increasing number of benign and non-life threatening causes of HPVG. HPVG is not by itself a surgical indication and the treatment depends mainly on the underlying disease. The prognosis is related to the pathology itself and is not influenced by the presence of HPVG. Based on a review of the literature, we discuss in this paper the pathophysiology, risk factors, radiographic findings, management, and prognosis of pathologies associated with HPVG.展开更多
