About a third of the patients with decompensated liver cirrhosis have reduced arterial oxygen saturation and are sometimes cyanosed in the absence of any apparent lung or heart disease; There is a reduction of diffusing capacity without a restrictive ventilatory defect. The aim of this study was to determine diffusing capacities in patients with chronic liver- diseases. The diffusing capacities and arterial oxygen saturations were measured in 25 patients with chronic active hepatitis(CAH), 9 early cirrhotics (early LC), 36 cirrhotics(Child's class A) and 11 cirrhotics(Child's class B). The anterior tibial area was observed for pitting edema, and Thallium-201 test per rectum(shunt index) was done. Hypoxemia was not observed in all subjects. The number of cases with decreased pulmonary diffusing capacity (DLco) is 3/25(12.0%) for CAH, 3/9(33.3%) for CAH with early liver cirrhosis(LC), 17/36(47.2%) for LC(Child's class A) and 6/11(54.5%) for LC(Child's class B). The mean+/-standard deviation of Dlco(% predicred) are 93.1+/-12.1 for CAH, 85.7+/-12.3 for CAH with early LC, 82.2+/-14.7 for LC(Child's class A) and 80.4+/-6.9 for LC(Child's class B), There is a significant difference between DLco in CAH and that in LC(Child's class A)(p<0.01). Patients with higher shunt index(>0.3) had significantly lower DLco than these with lower shunt index(<0.3)(76.4+/-9.7% vs. 89.3+/-13.3%)(p<0.01). The DLco was also lower in patients with pitting edema(77.3+/-10.2%) than in those without pitting edema(85.5+/-13.8%) (p<0.01). These results summarized that the DLco was low in patients with cirrhosis and with higher shunt index(>0.3) or pitting edema. This may be due to an increased systemic blood flow shunt and an increased generalized interstitial edema. Pulmonary function tests including diffusing capacity may be useful as prognostic parameters in patients with chronic liver disease, especially in those with CAH or early LC.

Renal artery pseudoaneurysm after blunt renal trauma is an uncommon complication of delayed hemorrhage, and diagnostic difficulties are experienced due to its rarity. Delayed hemorrhage after renal trauma is a lifethreatening complication. Angiography is considered the gold standard to diagnose a traumatic renal artery pseudoaneurysm. We report here a case of delayed bleeding from a renal artery pseudoaneurysm that was diagnosed at 17 days after the injury and that was managed successfully with selective renal artery embolization without medical complication.

PURPOSE: Central venous catheterization is widely used to supply substantial amounts of fluids, total parenteral nutrition and hemodialysis in renal failure patients, as well as for measuring the central venous pressure. The most common complications encountered during central venous catheterization include catheter-related infections and subsequent sepsis. Therefore, when fever exists in patients with a central venous catheter, an immediate blood culture should be performed, and if the fever persists, an infection must be suspected and the catheter immediately removed; a culture of the catheter tip should also be performed. To date, no definite clinical details relating to this matter have been reported. METHODS: Between December 2002 and March 2005, a retrospective study was undertaken using the medical records of 85 patients. In those patients where a fever lasted for more than 8 hours, or when catheterization was no longer needed, the catheter tip cultures were sent to the microbiology laboratory. Blood cultures were also performed on 49 patients with a fever. The Chi-square method using the PC SPSS program, with P value less than 0.05 as statically significant. RESULTS: Of the 85 patients where the catheters were removed, significant microorganisms were detected 20 of the 49 with a fever. Only 5 of the remaining 36 patients had their catheters spontaneously removed. Moreover, 14 of the 20 patients with significant microorganisms were found to have kept their catheter in place for more than 14 days. Of the 49 patients with a fever, in who blood cultures were undertaken, 13 showed specific microorganisms, with 6 of these showing the same results for both their blood and catheter tip cultures, which enabled the definite diagnosis of the catheter-related infection and underlying sepsis. Various microorganisms were detected from the catheter tip cultures, including Staphylococcus species the CNS, with S. aureus being the most common, at 61.6%. CONCLUSION: A central venous catheter should be removed immediately when an infection is suspected, but early broad-spectrum antibiotics therapy should be commenced due to the time required to obtain the culture results. Moreover, even if a fever does not exist in patients with a catheter inserted for more than 14 days, infection and sepsis from the catheter should be of concern, with a more cautious approach being mandatory.
