OBJECTIVE: To analyze in a multicenter study the potential benefit of a new prospective policy development to increase split-liver procedures for 2 adult recipients. BACKGROUND: Split-liver transplantation is an important means of overcoming organ shortages. Division of the donor liver for 1 adult and 1 pediatric recipient has reduced the mortality of children waiting for liver transplantation but the benefits or disadvantages to survival when the liver is divided for 2 adults (adult-to-adult split-liver transplant, AASLT) compared with recipients of a whole graft have not been fully investigated. METHODS: We developed a computerized algorithm in selected donors for 2 adult recipients and applied it prospectively over a 12-year period among 7 collaborative centers. Patient and graft outcomes of this cohort receiving AASLT either as full right grafts or full left grafts were analyzed and retrospectively compared with a matched cohort of adults who received a conventional whole-liver transplant (WLT). Univariate and multivariate analysis was done for selected clinical variables in the AASLT group to assess the impact on the patient outcome. RESULTS: Sixty-four patients who received the AASLT had a high postoperative complication rate (64.1% grade III and IV) and a lower 5-year survival rate than recipients of a WLT (63.3% and 83.1%) CONCLUSIONS: AASLT should be considered a surgical option for selected smaller-sized adults only in experimental clinical studies in experienced centers.

An independent clinical assessment was compared with flow cytometry (FCM) and cytomorphology results obtained on 227 cerebrospinal fluids investigated for hematologic malignancy, in a retrospective longitudinal study with a median observation time of 11 months. A combined method assessment (CMA), defining "positive" a sample if at least one method gave "positive" results, was also tested. Eleven out of 55 screening samples and 53 out of 166 follow-up samples resulted positive at clinical evaluation. FCM and CM were concordant with positive clinical assessment in 68.5% and 51.5% of cases, respectively. According to CMA, 10.5% of samples (resulting false negative by either FCM or cytomorphology) were rescued as true positive. FCM retained significantly higher accuracy than cytomorphology (p = 0.0065) and 100% sensitivity when at least 220 leukocytes were acquired. CMA accuracy was higher than FCM accuracy and significantly higher than cytomorphology accuracy in the analysis of all samples (p < 0.0001), samples from mature B/T cell neoplasms (p = 0.0021), and samples drawn after intrathecal treatment (p = 0.0001). When acquiring ≥220 leukocytes, FCM accuracy was poor, and combining cytomorphology added statistically significant diagnostic advantage (p = 0.0043). Although FCM is the best diagnostic tool for evaluating CSF, morphology seems helpful especially when clinically positive follow-up samples are nearly acellular. © 2011 Springer-Verlag.

Background/Aims: Mutual interactions between portal vein and hepatic artery can be documented during hepatobiliary surgery. Associating Liver Partition and Portal Vein Ligation for Staged Hepatectomy (ALPPS) is a recently introduced surgical technique which can also represent a unique living human model to investigate intrahepatic blood circulation. We report three consecutive cases in which a residual right portal branch flow was clearly detectable after first-step ALPPS, and try to further investigate this unexpected finding with intraoperative clamping tests. Methodology: Every patient was evaluated with CT scan 7 days after first-step ALPPS and Intraoperative Doppler Ultrasonography (IOUS) at both steps of the procedure. Results: In every patient, CT scan and second-step IOUS demonstrated a clear hepatopetal flow distally to the divided right portal branch. The flow was present after right biliary duct clamping and stopped after right total hilar clamping as well as after right hepatic artery occlusion. Conclusions: Neither cross-portal circulation between the two hemilivers nor trans-sinusoidal backflow from the hepatic veins can explain these findings, which are rather consistent with a refilling of the occluded portal branch through the opening of intrahepatic arterioportal shunts (APS). APS could represent the simplest homeostatic mechanism that regulate intrahepatic blood flow. © H.G.E. Update Medical Publishing S.A.

The 'real time' capability of ultrasound (US) allows dynamic assessment of joint and tendon movements, which can often aid in the detection of structural abnormalities. The simultaneous use of arthroscopy (AS) and US is therefore a logical progression. Here the results of a series of 11 patients with different rheumatic diseases in whom a combined use of US and AS was adopted are reported. © 2013 Informa UK, Ltd.

Flow cytometry and cytomorphology results on 92 body cavity fluids [61 effusions and 31 bronchoalveolar lavage fluids (BALF)] from hematologic malignancy were compared with retrospective clinical outcome. We observed double true positive/negative results in 67 cases (73%), and double false negative results in 2 cases (2%). Immunophenotyping accounted for true positive/negative results in 22 out of 23 mismatched cases (25%), and retained significantly higher accuracy than that of cytomorphology especially in effusions and differentiated lymphoma. In BALF analysis, immunophenotyping and cytomorphology sensitivity was 75% and 0%, respectively. Flow cytometry retains the highest accuracy in detecting neoplastic cells in body cavity fluids. © 2010 Elsevier Ltd.

Purpose: Spondylodiscitis mainly affects the anterior part of the spine. In this paper, we retrospectively analyze our experience with the anterior stand-alone approach (ASAA) in the treatment of spinal infections. Methods: Forty consecutive patients with severe spondy-lodiscitis underwent the ASAA during the acute infective phase. Treatment consisted of disease debridement, vertebral body reconstruction using titanium expandable pros-theses and anterior fixation. Results: There was neither mortality nor major morbidity. Successful arthrodesis was achieved in 39 out of 40 patients who remained disease free throughout the follow-up period. Six months after treatment, one patient experienced pseudarthrosis and required supplemented posterior spinal fixation for vertebral instability. However, adequate arthrodesis was eventually obtained even in this patient. Conclusions: ASAA with spine reconstruction using synthetic materials during the acute infection phase was safe and effective. The infections were rapidly defeated, the patients were allowed to stand up early after the procedure and the length of hospital stay was significantly reduced. © Springer-Verlag 2012.
