In this study, we investigated possible independent predictive factors for survival, other than MELD score, in patients with
cirrhosis. We reviewed the serum sodium, cholesterol, albumin, and platelet levels of 99 patients with cirrhosis and investigated
the possible correlation of these parameters with survival period. We found that 77% and 81% of patients with cirrhosis were
hypocholesterolemic and hypoalbuminemic, respectively. We noted that the survival time of 6 months in patients with serum
sodium levels <125 mM at the time of admission to the study was 27% less than that in patients with sodium levels >130 mM.
Patients with cirrhosis and serum sodium levels >130 mM survived for more than 1 year (95% CI). MELD scores of patients with
serum sodium levels >130, between 125 and 129, and <125 mM were 15.8 to 19.9, 19.7 to 23.6, and 23.3 to 27.2, respectively
(95% CI). In conclusion, we suggest that although all of these parameters are correlated with survival in patients with cirrhosis,
the serum sodium level is the most accurate prognostic factor and a valid tool for predicting survival when considered in
combination with the MELD score. 相似文献

In patients with acute pulmonary embolism (PE) the frequency of deep vein thrombosis (DVT) varies between 13–93%. The aim
of this study was to compare Doppler ultrasonography (DUSG) and venography in the detection of DVT in patients with PE. Fifty-one
patients who were clinically diagnosed as having PE from January 1st 2001 to January 31st 2005 were entered into the study
and comorbid conditions and risk factors were noted. The diagnosis of PE was confirmed by ventilation-perfusion (V/Q) scintigraphy,
spiral tomography and angiotomography while the diagnosis of DVT was made by DUSG and venography. DVT was confirmed by both
DUSG and venography in 19 (37,3%) patients. In the remaining 32 patients DUSG was negative. Venography confirmed DVT in 6
of these patients while in 26 no DVT was found. The sensitivity and specifity of DUSG in the diagnosis of DVT were 76% and
100% respectively and the negative and positive predictive values were 81% and 100% respectively. The mean d-dimer concentration
was 1187 in patients with DVT and 641 in patients without DVT (p > 0.05). Aquired risk factors were found in 4 of 6 patients with DVT, CRP was elevated in 5 (83%) and ALT-AST were elevated
in 2 (33%). Although DUSG alone is considered sufficient for the diagnosis of DVT, venography still remains the gold standard
in the diagnosis of DVT. Especially in patients with PE, where the diagnosis of DVT may increase the success of treatment,
venography or other diagnostic tools may be used instead of a second DUSG if the first DUSG is negative. 相似文献

Cadmium (Cd) is a heavy metal which affects many systems in humans and animals as a consequence of environmental and industrial pollution. The aim of this study was to investigate the effect of chronic Cd toxicity on blood pressure and plasma viscosity. Experimental group rats were given doses that contained 15 ppm CdCl(2) in drinking water for 8 weeks. The systolic blood pressure and heart rate were measured from rats' tails and recorded by plethysmography every two weeks. Blood samples were drawn, Cd levels were determined by atomic absorption spectrophotometer and plasma viscosity values by viscometer. Blood Cd levels were found to be significantly higher in the experimental group compared to the control group (p < 0.001). The whole blood analysis was made by an analyzer. Polymorphonuclear leukocytes and monocytes increased (p < 0.01) and lymphocyte number (p < 0.05) decreased in the experimental group. Viscosity values were 2.21 ± 0.54 and 1.62 ± 0.31 centipoises in the experimental and control groups, respectively (p < 0.001). In the experimental group, changes in systolic blood pressure between weeks were significant (p < 0.001) and were found to be correlated with plasma viscosity (p < 0.001). In the experimental group, changes in heart rate between weeks were significant (p < 0.001). According to our findings, Cd toxicity may lead to an increase in blood pressure by increasing plasma viscosity. 相似文献

This study was carried out to determine the serum levels of high mobility group box protein 1 (HMGB1) in patients with ankylosing spondylitis (AS) and to evaluate its correlation with disease activity and quality of life. According to our knowledge, it is the first trial evaluating HMGB1 levels in AS. Serum samples of 30 patients (18 males and 12 females) with AS and 29 healthy controls (HC) (15 females and 14 males) were collected. HMGB1 levels were measured by enzyme-linked immunosorbent assay, activity of disease was assessed according to the Bath AS Disease Activity Index (BASDAI), and functional status of patients was evaluated with Bath AS Functional Index (BASFI). Modified Schober, chest expansion values and AS Quality of Life Questionnaire (ASQoL) scores were noted. The serum levels of HMGB1 were obtained significantly increased in AS patients compared to HC (p < 0.05). There was no significant correlation between HMGB1 levels and ESR (p > 0.05), and CRP (p > 0.05) values. BASDAI, BASFI and ASQoL scores were also not correlated with serum levels of HMGB1 (p > 0.05). Our results suggest that HMGB1 might play an important role in the pathogenesis of AS; however, it seems not to be a good candidate for reflecting disease activity, functional abilities and the quality of life in patients with AS; on the other hand, the increased levels of HMGB1 in patients may open a new dimension for targeting this cytokine as a new therapy option in AS. 相似文献

Endometriosis, an important gynecological disorder of reproductive women, affects most commonly the ovaries and less frequently the gastrointestinal tract, chest, urinary tract, and soft tissues. Endometriosis classically appears on MRI as a mass with a large cystic component and variable signal intensities on T1- and T2-weighted images due to the presence of variable degradation of hemorrhagic products. Endometriosis in an atypical location, an infiltrative appearance and without cystic-hemorrhagic components has rarely been described. We report on a 33-year-old woman with cyclic sciatica due to histologically documented infiltrative endometriosis involving the area of the left sciatic notch. 相似文献

OBJECTIVE: To measure the distances between the internal mammary arteries (IMAs) and the sternum for determining a route for parasternal transthoracic interventions. METHODS: Coronal reconstructed multidetector computed tomography images of 202 patients were evaluated to measure the distances between the IMAs and sternum at 3 levels (manubrium, midsternal corpus, and distal sternal corpus). The arrangements (2 veins-single artery or single vein-single artery) were documented. RESULTS: The most frequently encountered arrangement (42.1%) was a single vein and single artery on both sides. Mean distances on the right and left sides were 10.2 and 10.1 cm at the manubrium, 14.5 and 14.3 cm at the midsternal corpus, and 17.9 and 17.5 cm at distal sternal corpus, respectively. CONCLUSION: To be aware of the courses of the IMAs at different sternal levels is important during attempts at transthoracic intervention via a parasternal approach. 相似文献
