    Notizen: Abstract The capabilities of computed tomography (CT), ultrasonography (US), and magnetic resonance (MR) imaging were studied in order to determine the role of each of these noninvasive examinations for estimating the T-factor of hepatocellular carcinomas (HCCs). Fifty-one patients with surgically proven HCCs received CT (50 patients), US (46 patients), and MR (44 patients). The images of CT, US, and MR were prospectively evaluated for main tumor size, intrahepatic metastases, and vascular invasion, which compose the T-factor of HCC, and compared to pathological results. The sizes of the main tumor were estimated correctly by all examinations. For estimating intrahepatic metastases, US (74%) and MR (73%) were superior to CT (65%). For estimating portal invasion, CT (79%) was superior to US (70%) and MR (66%), because CT could demonstrate the segmental staining caused by portal invasion. The estimates of hepatic venous invasion were difficult during any of the examinations. We conclude that presurgical evaluations of the T-factor require the use of US and CT or MR and CT.

    Notizen: Abstract To investigate the characteristics, risk factors, and prevention of methicillin-resistant Staphylococcus aureus (MRSA), a total of 3,627 patients were studied. Among these, 1,336 patients with various infections were used in a risk factor analysis of MRSA to determine the relationship between the use of antibiotics and the incidence of MRSA. Only 3.0% of infections were attributed to MRSA, the esophagus and colorectal region being highly involved, as anastomotic or pelvic abscesses, while the lung had a lower incidence. Almost half the patients with MRSA infections (47.6%) had concomitant infections. A univariate analysis revealed the following significant factors: The coexistence of gastrointestinal or metastatic malignancy, sepsis, tracheostomy, and the prior use of antibiotics such as the β-lactam compounds or aminoglycosides. A multivariate analysis showed that gastrointestinal malignancy, sepsis, and the prior use of aminoglycosides, tetracycline, macrolides, and carbapenems were independently significant factors. To promote the education of doctors and nurses, regular in-service meetings on MRSA were held in the ward. Moreover, preventive approaches such as patient isolation, strategically placed hand washing equipment, and the use of disposable gloves and contaminated waste bags, have been initiated, and the incidence of MRSA has decreased significantly since then. Thus, to control MRSA, the following steps should be taken: (1) constant and careful surveillance, (2) regular risk factor analyses, (3) the optimal administration of antibiotics, and (4) the education of all hospital staff.

    Notizen: Abstract The regenerative capacity of the liver was assessed using a volumetric method on computed tomography in 21 adults: 16 underwent a standard right hepatic lobectomy for hepatocellular carcinoma, there were hepatic metastases in 3 others, and 2 suffered from other diseases. The patients' ages ranged from 33 to 68 years with a mean age of 57.0 years. The regeneration rate was expressed as the rate of the volume increase of the remnant left lobe compared with the preoperative volume of the left lobe. A univariate regression analysis showed that the portal pressure had a highly inverse correlation with the regeneration rate of the liver (r = −0.4753,P = 0.0397), while a multiple regression analysis demonstrated the correlation between the portal pressure, age, and the regeneration rate (multipler = 0.5640). The regeneration rate of the normal liver (97.6 ± 53.5%) was significantly higher than that of the chronic hepatitic (43.0 ± 40.7%), and also tended to be higher than that of the cirrhotic liver (51.5 ± 13.2%). However, there were no differences between chronic hepatitic and cirrhotic livers. The portal pressure before hepatectomy of the normal liver (149 ± 19 mmH2O) was significantly lower than those of chronic hepatitic (188 ± 38 mmH2O) and cirrhotic (245 ±78 mmH2O) livers. We thus conclude that the regenerative capacity of the liver following a right hepatic lobectomy could be estimated on the basis of both portal pressure and age. The regenerative capacity was also influenced by underlying liver diseases.
