BACKGROUND: Intrahepatic biliary cystadenoma (IBC) is a rare liver tumour, which has strong tendency to recur and malignant potential as it can progress to cystadenocarcinoma (IBCa). METHODS: From June 2003 to December 2006, four patients diagnosed with hepatic cystadenoma were operated on our Liver Surgical Unit. All patients were females with median age of 51 years (range 45-63 years). Liver resections included three left and one right hepatectomies. In two patients, IBC was diagnosed by abdominal imaging and serum tumour markers but the rest of the patients were initially misdiagnosed as simple cysts, treated by laparoscopic fenestration and referred to our unit after cyst recurrence. RESULTS: In all cases, the pathology report was consistent with liver cystadenomas. The postoperative course was uneventful and the median hospital stay was 8 days (range 5-12 days). In a median 18-month follow-up (range 2-40 months), all patients are alive and free of recurrence. CONCLUSION: Liver cystadenomas can be easily misdiagnosed with other hepatic cystic lesions. An aggressive surgical approach is recommended, due to their malignant potential and high recurrence rate after fenestration. 相似文献

Introduction
The reliability of autocalibrated pressure waveform analysis by the FloTrac-Vigileo® (FTV) system for the determination of cardiac output in comparison with intermittent pulmonary arterial thermodilution (IPATD) is controversial. The present prospective comparison study was designed to determine the effects of variations in arterial blood pressure on the reliability of the FTV system in patients undergoing coronary artery bypass grafting (CABG).Methods
Comparative measurements of cardiac output by FTV (derived from a femoral arterial line; software version 1.14) and IPATD were performed in 16 patients undergoing elective CABG in the period before institution of cardiopulmonary bypass. Measurements were performed after induction of anesthesia, after sternotomy, and during five time points during graft preparation. During graft preparation, arterial blood pressure was increased stepwise in intervals of 10 to 15 minutes by infusion of noradrenaline and lowered thereafter to baseline levels.Results
Mean arterial blood pressure was varied between 85 mmHg and 115 mmHg. IPATD cardiac output did not show significant changes during periods with increased arterial pressure either during sternotomy or after pharmacological manipulation. In contrast, FTV cardiac output paralleled changes in arterial blood pressure; i.e. increased significantly if blood pressure was raised and decreased upon return to baseline levels. Mean arterial blood pressure (MAP) and FTV cardiac output were closely correlated (r = 0.63 (95% confidence interval [CI]: 0.49 - 0.74), P < 0.0001) while no correlation between MAP and IPATD cardiac output was observed. Bland-Altman analyses for FTV versus IPATD cardiac output measurements revealed a bias of 0.4 l/min (8.5%) and limits of agreement from 2.1 to -1.3 l/min (42.2 to -25.3%).Conclusions
Acute variations in arterial blood pressure alter the reliability of the FlowTrac/Vigileo® device with the second-generation software. This finding may help to explain the variable results of studies comparing the FTV system with other cardiac output monitoring techniques, questions the usefulness of this device for hemodynamic monitoring of patients undergoing rapid changes in arterial blood pressure, and should be kept in mind when using vasopressors during FTV-guided hemodynamic optimization. 相似文献104.

PURPOSE: Bisphosphonates are compounds used in the treatment of various metabolic and malignant bone diseases. In the last two and a half years, there has been a striking increased referral of patients with exposed necrotic jawbone, mostly after several teeth extractions. The only clinical feature common in all patients was the use of bisphosphonates in the treatment of bone diseases. PATIENTS AND METHODS: We performed a retrospective multicentric study of 60 patients with necrotic bone lesions of the jaws of various extent from July 2003 to October 2005. The necrotic bone involved the maxilla (37%), the mandible (50%), or both (13%). The bisphosphonate administered was mostly zoledronate. The management of the patients included cessation of bisphosphonate therapy for more than 6 months, long-term antibiotics, hyperbaric oxygen administration in some cases, and various surgical restorative procedures. RESULTS: The implementation of the treatment protocol in 7 patients so far lead to high cure rates, whereas surgical restoration of the defect without previous cessation of bisphosphonate therapy had discouraging results. CONCLUSIONS: Clinicians and dentists should have in mind this new complication of bisphosphonate administration to identify and treat osteonecrosis of the jaws. 相似文献
