Pseudoaneurysm (PA) is a rare but life-threatening complication of liver transplantation. The authors present their experience on 7 patients treated by ligation of a post-OLT PA. Hepatic artery ligation or embolization was performed from 10 to 70 days after liver transplantation. Of the seven patients, four survived, one developed a biliary stricture, treated by percutaneous balloon dilatation, two died of a complication not related to treatment, and one died of multiple organ failure.
IntroductionThe aim of this multicenter, phase III, prospective open label clinical trial was to investigate the effect of risedronate (R) on bone mineral density (BMD) in postmenopausal, early breast cancer (BC) patients scheduled to receive anastrozole (A).MethodsPre-treatment BMD of 213 patients with hormone receptor-positive BC was evaluated at lumbar spine (LS) and hip (HP). Patients were categorized according to their baseline BMD T-score as being at low, moderate and high risk of osteoporosis. Low risk patients received anastrozole only (A), moderate risk were randomized to anastrozole +/- risedronate (A+/-R) administration and high risk patients received anastrozole + risedronate (A+R). Anastrozole was given at a dosage of 1 mg/day while oral risedronate was given at 35 mg/week. BMD was then assessed at 12 and 24 months. All patients received daily supplements of calcium (1000 mg/day) and vitamin D (400 IU/day).ResultsAt 24 months, in the moderate risk group, treatment with A+R resulted in a significant increase in BMD at LS and HP compared to treatment with A only (5.7% v -1.5%, Wilcoxon test P = 0.006, and 1.6% v -3.9% Wilcoxon test P = 0.037, respectively), while no significant difference was found at 12 months; 24.3% of the patients moved to normal BMD region. In the high risk group, a significant increase for LS was detected both at 12 and 24 months (6.3% and 6.6%, P < 0.001) but not for HP; BMD in 14% of patients improved to the osteopenic region. In the low risk group, a significant decrease of BMD was detected at 12 months for LS and HP (-5.3% P < 0.001 and -2.4% P < 0.001, respectively,); at 24 months, a significant decrease of BMD was detected only for LS (-2.5%, P < 0.001). However, 22% of patients became osteopenic and only 4% became osteoporotic.ConclusionsThe addition of oral risedronate in post-menopausal breast cancer patients receiving anastrozole has a favorable effect on BMD. Patients with pre-treatment osteopenic to osteoporotic status should be treated with a combination of both therapies in order to avoid bone loss induced by aromatase inhibition. Patients with normal BMD before starting treatment with anastrozole have a very low risk to develop osteoporosis.Trial registrationClinicalTrials.gov Identifier NCT00809484.
Hepatic hydatidosis presents a challenge in liver surgery, and there is still controversy regarding the appropriate surgical technique. A high incidence of postoperative bile leaks is reported as a significant disadvantage of conservative surgical procedures. The purpose of this study was to examine the incidence and clinical importance of bile leakage in patients being treated exclusively by a conservative surgical technique. From January 1985 to November 2000 a total of 187 patients were operated on at our department for hepatic hydatidosis. They were subjected to the standard conservative surgical technique (wide unroofing and cyst drainage). A total of 18 complications were related to bile leakage (10%), 3 of them bile abscesses (1 drained surgically and 2 percutaneously), 1 case of bile peritonitis due to an accessory bile duct in the gallbladder bed (treated surgically), and 14 fistulas (1 bronchobiliary and 13 biliocutaneous). Five of the fistulas, including the bronchobiliary one, were treated successfully by endoscopy; and the remaining nine healed after conservative treatment. Bile leakage, representing a significant complication following conservative operations for hepatic hydatidosis, can be effectively treated conservatively or endoscopically, not justifying more aggressive surgical approaches.
Introduction Extended adjuvant endocrine therapy for breast cancer with aromatase inhibitors may potentially alter the lipid profile of postmenopausal patients and thus increase the risk of developing cardiovascular disease. In this study, a subprotocol of the ATENA (Adjuvant post-Tamoxifen Exemestane versus Nothing Applied) trial, we compared the effect of the steroidal aromatase inactivator exemestane on the lipid profile of postmenopausal patients with operable breast cancer, in the adjuvant setting, with that of observation alone after completion of 5 to 7 years of primary treatment with tamoxifen.
Although the incidence of pneumonia after kidney transplantation is the lowest among all solid organ transplants, it is associated with high mortality rate (40-50%). We evaluated the efficacy of a protocol consisting of bronco-alveolar-lavage (BAL) for early microbiological diagnosis, reduction of the immunosuppressive therapy, and prompt administration of standardized antibiotic regimen in renal transplant recipients with severe pneumonia. Between 6/1989 and 5/1999, 40 kidney transplant recipients developed 46 episodes of severe pneumonia (hypoxia and/or infiltrate on the chest X-ray). According to protocol, in all these cases, a BAL was immediately performed and empirical antibiotic therapy was initiated with erythromycin and trimethoprim-sulfamethoxazole i.v. Furthermore, the immunosuppressive therapy was drastically reduced. Analyses of BAL fluid included cell differential count, cytopathologic examination and cultures for bacteria, fungi and viruses. Within 48 h, the therapy was switched to proper i.v. antibiotics, if necessary, according to the results of sensitivity testing of BAL specimens. The mortality rate was 12.5% (5 of 40). Mechanical ventilation was required in 20 cases (34.5%) and four of the patients that required intubation died. BAL alone established a diagnosis in 67.4% (31 of 46) of the patients. Bacteria were responsible for 61% of the episodes, with fungi responsible for 29% and viruses for 10%. Seven cases of Pneumocystis carinii pneumonia were treated with the prolongation of the initial therapy. We conclude that a combination of early detection of the responsible pathogen by BAL, aggressive reduction of the immunosuppressive therapy and the immediate empirical administration of erythromycin and trimethoprim-sulfamethoxazole is an effective strategy to treat pneumonia kidney transplantation (KTX) recipients.
