Abstract
BACKGROUND The first line of prevention of surgical site infection relies on the timely administration of antibiotic prophylaxis. First- and second-generation cephalosporins are the most recommended antibiotics in elective surgery. The incidence of cefazolin allergy has increased worldwide over the years. The sensitization mechanism of cefazolin is currently unknown, and data supporting cross-reactivity between penicillins and cephalosporins are lacking. Sensitization could occur through previous exposure either to cefazolin or to structurally related chemical agents. The objective of this study was to evaluate sensitization agents towards cefazolin. METHODS The OpenBabel chemoinformatics toolbox was used to search for similarities between cefazolin and other molecules in an extensive drug database. Using the pholcodine-rocuronium similarity score as a threshold, we selected drugs with the most similar structure to that of cefazolin. Exposure to those drugs and cefazolin was assessed in a cohort of patients with skin test-proven cefazolin allergy at a specialized allergy centre via a self-administered anonymous questionnaire. RESULTS Using the pholcodine-rocuronium similarity score as a threshold (score≥0.7), 42 molecules were found to be similar to cefazolin (all cephalosporins). Only 8 were marketed in France. None of the 14 cefazolin-allergic patients who answered the questionnaire (65% female, median age 56 years) reported exposure to any identified antibiotics. In contrast, 11 (78%) had at least one previous surgery requiring cefazolin before the index case. CONCLUSION Direct previous cefazolin exposure was identified in 78% of cefazolin-allergic patients. Cefazolin started to take a central place in antibiotic prophylaxis after 2010, when cefamandole usage decreased drastically. Changes in antibiotic prophylaxis over the past 14 years in France could have been the turning point for the increased incidence of cefazolin allergy.

Abstract
We report 3 cases of a new renal cell tumor entity with a review of the literature. These 3 cases were retrieved from the files of this institution from 1991 to 2002. The clinical data and all histologic slides were reviewed and an immunohistochemical study was performed. Patients were all females. Tumors were almost similar with well-defined margins. Tumor architecture was tubular and focally fusiform with an abundant myxoid stroma. Tumor cells were low cuboidal, slightly eosinophilic with low nuclear grade. Immunohistochemistry was in favor of a distal nephron differentiation. All patients were healthy after surgery. We describe 3 cases of a new clinicopathological entity entitled low-grade tubular myxoid renal tumor with a benign clinical course.

Abstract
Endocarditis due to Legionella spp. is uncommon but presumably underestimated given the prevalence of Legionellae in the environment. We report a first and unusual case of chronic native valve endocarditis due to L. anisa and advocate that the diagnosis of endocarditis be made collaboratively between the cardiologist, surgeon, microbiologist and pathologist.

Abstract
Since the introduction of the 64-generation scanners, the accuracy and robustness of the diagnosis of coronary artery disease has progressed. The main advantage of cardiac CT is the exclusion of coronary artery disease by its excellent negative predictive value. Currently, cardiac CT applications extend thanks to innovations both in terms of technological development systems scanner or stents implanted, that the evolution of surgical procedures such as TAVI.

Abstract
Morbidity from calcific aortic valve disease (CAVD) is increasing. Recent studies suggest early reversible changes involving inflammation and neoangiogenesis. We hypothesized that microcalcifications, chemokines, and growth factors are present in unaffected regions of calcific aortic valves.
We studied aortic valves from 4 patients with CAVD and from 1 control, using immunohistochemistry, scanning electron microscopy, and infrared spectrography. We revealed clusters of capillary neovessels in calcified (ECC), to a lesser extent in noncalcified (ECN) areas. Endothelial cells proved constant expression of SDF-1 in ECC, ECN, and endothelial cells from valvular surface (ECS). Its receptor CXCR4 was expressed in ECC. IL-6 expression correlated with CXCR4 staining and presence of lymphocytes. VEGF was expressed by ECS, its receptor by ECC and ECN. Crystalline ultrastructures were found on the surface of histologically noncalcified areas (HNCAs), spectrography revealed calcium hydroxylapatite. Our results demonstrate that crystalline ultrastructures are present in HNCAs, undergoing neoangiogenesis in an inflammatory context. These alterations could be an early witness of disease and an opening to therapy.

Abstract
Background: Activator protein-2α (AP-2α) is a transcription factor that belongs to the family of AP-2 proteins that have essential roles in tumorigenesis. Indeed, AP-2α is considered as a tumour-suppressor gene in different tissues such as colonic, prostatic or breast epithelial cells. Moreover, AP-2α also participates in the control of colon and breast cancer cells sensitivity towards chemotherapeutic drugs. Despite its potential interest, very few data are available regarding the roles of AP-2α in pancreatic cancer. Methods: We have developed a stable pancreatic CAPAN-1 cell line overexpressing AP-2α. Consequences of overexpression were studied in terms of in vivo cell growth, gene expression, migration capacity and chemosensitivity. Results: In vivo tumour growth of CAPAN-1 cells overexpressing AP-2α was significantly decreased by comparison to control cells. An altered expression pattern of cell cycle-controlling factors (CDK-4, CDK-6, cyclin-G1, p27kip1 and p57kip2) was observed in AP-2α-overexpressing clones by microarrays and western blot analysis. Promoter activity and ChIP analysis indicated that AP-2α induces p27kip1 protein levels by direct binding to and transactivation of its promoter. Moreover, AP-2α overexpression increased the chemosensitivity of CAPAN-1 cells to low doses of gemcitabine and reduced their in vitro migration capacity. Conclusion: Our data suggested that AP-2α overexpression could be exploited to decrease in vivo tumour growth of pancreatic cancer cells and to increase their sensitivity to gemcitabine.

Abstract
BACKGROUND Using echocardiography, perioperative assessment of systolic function by fractional area change (FAC) is questionable in patients suffering from mitral regurgitation (MR). Tei index, an index expressing global cardiac function, has been reported to be unchanged after mitral valve surgery. We tested the hypothesis where the Tei index could be useful in assessing the perioperative cardiac function in patients undergoing mitral valve repair (MVR). METHODS Twenty-five patients were enrolled. Transoesophageal echocardiography was performed perioperatively before and after the correction of MR. We compared the impact of the MVR on the left ventricular FAC and the Tei index. FAC was calculated from the transgastric short-axis view and Tei index was determined from the four chambers and deep transgastric views. RESULTS Two patients were excluded because of poor acoustic windows. FAC significantly decreased after MVR from 53 (9)% to 42 (10)% (P<0.001), while Tei index was unaffected [0.46 (0.16) vs 0.47 (0.17), NS]. A significant relationship was found between the preoperative Tei index and the postoperative FAC (R=-0.64, P<0.001). Moreover, a significant and clinically relevant relationship was determined between the predicted (using preoperative Tei index) and the measured postoperative FAC (R=0.64, P<0.001). CONCLUSIONS FAC but not the Tei index is influenced by MVR. The preoperative determination of the Tei index allows predicting postoperative FAC and offers the opportunity to identify patients in whom a severe unsuspected systolic dysfunction could render difficult the weaning from cardiopulmonary bypass.

Abstract
BACKGROUND Optimal treatment of type B dissections is open to debate. The use of endoprostheses is an option that requires evaluation. AIM To report our experience with endoprostheses in type B aortic dissections. METHODS We report our short- and medium-term results with covered prostheses for the treatment of acute (n=7) and chronic (n=28) type B aortic dissections. The criteria used to indicate treatment were the same as those usually used for surgery: acute complications or dilated aneurysm. Cover of the main intimal tear was obtained in all cases with an improvement in symptoms in patients with acute dissections. RESULTS Early mortality was 14.3% (five patients), linked in three cases to the occurrence of a retrograde dissection of the ascending aorta. No neurological complications were observed. Four patients required an additional endovascular and/or surgical procedure. On early control scans, complete thrombosis of the false lumen at the thoracic level was observed in 40% of cases, partial thrombosis in 42.8% and an absence of thrombosis in 11.4%. After a mean follow-up of 20.8 months, one patient died of a pneumopathy. No secondary aneurysm expansion was noted at the thoracic stage whereas three patients presented with dilation of the abdominal aorta. CONCLUSION The results of treatment of type B dissections with covered endoprostheses are encouraging. However, the morbimortality associated with treatment and the uncertainty of long-term results do not allow the use of this therapeutic option outside the criteria usually recognized to indicate surgery.

Abstract
INTRODUCTION Reperfusion (or hyperperfusion) syndrome may be a possible complication of carotid artery endarterectomy or angioplasty. OBSERVATION We report the case of a 54-year-old man who underwent a right carotid endarterectomy for an asymptomatic carotid stenosis and developed reperfusion syndrome a few days after surgery. The symptoms were marked by a prolonged partial epileptic status and then left hemiplegia lasting several days. Brain MRI with Diffusion sequences was normal, whereas there was a right frontoparietal hypersignal in FLAIR sequences, suggesting the presence of brain vasogenic oedema. Clinical and neuroradiological outcomes were good, confirming the relative good prognosis attributed to vasogenic brain oedema in previous similar publications. This condition may be misdiagnosed as cytotoxic brain oedema, another possible complication of carotid endarterectomy, whose management and prognosis are different. CONCLUSION When a focal neurological deficit or epileptic seizures follow carotid artery endarterectomy, it is important to consider reperfusion syndrome. MRI (with FLAIR and Diffusion sequences) will show a vasogenic brain oedema, with a better prognosis than what can be expected with cytotoxic oedema.

Abstract
INTRODUCTION We sought to examine the results of orthotopic heart transplantation accepting hearts from donors >50 years of age with special regard to the usefulness of peripheral extracorporeal membrane oxygenation for posttransplant graft dysfunction. PATIENTS Between January 2000 and December 2004, a total of 247 patients underwent orthotopic heart transplantation. In 143 patients (58%) the heart donor was <50 years (group I, mean age of donor hearts 36 +/- 11 years; range, 8-49 years). In 104 recipients (42%) the heart donor was >50 years (group II, mean age of donor hearts 56 +/- 15 years; range, 50-67 years). Pretransplant characteristics of the two groups showed no significant differences. RESULTS The in-hospital mortality was slightly increased in group II (24% vs 20% in group I, NS) and the 5-year survival rate significantly increased in group I (75% vs 63% in group II). Freedom from transplant vasculopathy after 3 years was similar in both groups (86% in group I vs 87% in group II). A total of 25 patients (17%) in group I and 27 patients (26%) in group II developed graft dysfunction. Eleven patients in group I and 10 patients in group II were treated using peripheral extracorporeal membrane oxygenation, whereas 3 of the 11 patients in group I and 5 of the 10 patients in group II were discharged following a complete recovery. Two patients in group I and 4 patients in group II were survivors beyond year. CONCLUSION In our experience it was possible to increase the cardiac donor pool by accepting allografts from donors >50 years of age in selected cases. The incidence of transplant vasculopathy was not increased, whereas in-hospital mortality was slightly higher. In our limited cohort, patients with older donor hearts was developed graft dysfunction profited from primary extracorporeal membrane oxygenation implantation, an indication that should be examined further without delay.

Abstract
AIM To report the description of a rare benign osseous lesion affecting the ribs entitled post-traumatic fibro-osseous lesion (PTFOL). METHODS Seven cases of PTFOLs were retrieved from the archives of the University Hospital of Lille. Histological slides were reviewed and lesions were classified according to the histological patterns described by McDermott et al. Clinical and follow-up data were obtained from the patients' charts. RESULTS PTFOLs occurred principally in men (mean age 31.8 years) with a known or suspected previous chest injury for four of them. No previous cancer was noted. Radiologically, PTFOLs readily presented as an isolated expansive lucency with a sclerotic rim located on the last five ribs. A constant increased uptake of radionucleotide was noted on bone scan. Microscopically, two fibro-osseous, four xanthomatous and one mixed pattern were individualised. Lesions were characterised by a network of anastomosing bone trabeculae without osteoblast lining within a fibrous stroma. A zonal maturation from woven to peripheral lamellar bone was characterised. Central sheets of lipid-laden histiocytes were conspicuous in the xanthomatous type. For each patient, clinical follow-up was excellent, without any recurrence. CONCLUSIONS This is the second largest series of PTFOLs, which is considered to be a dysplastic healing process after trauma. It may be symptomatic or shown by imaging studies realised for unrelated reason. PTFOL is regularly misdiagnosed with other more common lesions of the ribs, such as fibro-osseous dysplasia, osteoma osteoid and benign fibrous histiocytoma. Its recognition is of importance because no follow-up is needed after resection.

Abstract
A prospective 'analysis of operative risk and results in video-assisted mitral valve surgery performed in a non selected population is reported. Seventy two consecutive patients (1997-2004) with mean age 60 +/- 12 years underwent a video-assisted mitral valve procedure using a femoral CPB. A transthoracic direct aortic clamping was done in 28 patients (TT) and an endo-aortic occlusion balloon was used in 44 patients (Endo). The surgical approach was a right lateral minithoracotomy in all cases; 16 patients had a previous cardiac surgery. The expected mitral operation (39 repairs, 33 replacements) was done in all cases, without conversion. There were 4 early deaths (1 st month), all in Endo group: 1 aortic dissection, 1 heart failure and 2 sudden deaths. Postoperative complication occurred in 17 patients with 5 reoperations for hemostasis of the thoracic wall. Cumulative rate of mortality and morbidity was 29% in Endo and 28% in TT (ns). Hospital stay was 8 +/- 2 days. At discharge, 4 patients had a residual grade 2 echocardiographic mitral regurgitation after valve repair. In January 2005, with a 1.8 years follow-up, there were 4 late deaths, 3 patients underwent a valve reoperation, 2 patients were still in NYHA class 3 and 5 patients had a residual grade 1 or 2 mitral regurgitation. The 3-year actuarial survival was 86 +/- 10% and the 3-year probability to be free of reoperation was 95 +/- 6%. In mitral valve surgery, video-assisted approach is reliable, the operative risk is controlled and midterm results are not compromised. Video-assisted mitral valve surgery is a new less invasive standard; it is the procedure of choice in valve replacement, in reoperation and in non complex valve repair with good cosmetic results.

Abstract
INTRODUCTION We sought to report the usefulness of extracorporeal membrane oxygenation (ECMO) in heart transplant patients. PATIENTS Between March 2002 and August 2004, 14 heart transplant patients (11 men and three women, 36 +/- 15 years old, range = 12 to 50) with primary graft failure underwent peripheral ECMO implantation. Three patients had pulmonary hypertension and three had been transplanted with hearts from marginal donors. At the time of implantation, all were in severe cardiogenic shock despite maximal inotropic support. In six patients, the ECMO was implanted in the operating room since cardiopulmonary bypass could not be weaned. In the eight remaining patients, ECMO was implanted in the intensive care unit, during the first 48 hours in seven cases. In one patient, implantation was performed during external resuscitation. In all cases, femoral vessels were canulated using the Seldinger technique after anterior wall exposure. Distal arterial perfusion of the lower limb was systematically used. RESULTS Pump outflow was high enough in all the cases (mean: 2.6 +/- 0.2 L/min/m(2)). Three patients died on circulatory support. One patient was implanted with a total artificial heart after a few hours and another one underwent unsuccessful emergent retransplantation. Nine patients were weaned from ECMO after a mean duration of 5 +/- 2.5 days. Among them, one died of infection at 10 days after weaning and seven others were discharged to rehabilitation centers. CONCLUSION Fast operating room or bedside implantation of a peripheral ECMO allows the physician to stabilize the hemodynamic status of patients with cardiac graft failure, potentially leading toward myocardial recovery.

Abstract
OBJECTIVE Discursive abilities of severe brain injured patient are always impaired: loss of flexibility, lack of cohesion and coherence, often more elliptic. We know few about nonverbal competencies during discourse. The objective is to verify nonverbal abilities of these patients by pragmatic analysis. METHODS Four men were examined more than 7 years after severe traumatic brain injury. Nonverbal Prutting and Kirchner Pragmatic Protocol (1987) were done allowing to a qualitative and quantitative measurement of paralinguistic behaviour: prosody and quality of speech, facial expression, posture, gaze, gesture. Two conditions were recorded: dual (descriptive discourse) and group (conversational discourse). Associated impairments such as cognitive and dysexecutive functioning were also investigated. RESULTS/DISCUSSION Impoverishment (loss of ability) or impaired inadequacity was observed in all patients. Paralinguistic competences of conversational discourse was worse than descriptive one. Facial expression, gaze functioning, referential gesture were more often impaired. Maladjustment could be interpretated in reference with dysexecutive syndrome. CONCLUSION In spite of the lack of information about the range of normal pragmatic behaviour, it seems that brain injured patients have shown poor nonverbal abilities during discourse. Rehabilitation training of communication skills would integrate this fact in order to improve interactivity and social relationship.

Abstract
STUDY OBJECTIVES To examine the results of right heart derivations and clinical outcomes according to preoperative characteristics and operative strategy implemented. METHODS Fontan operations were performed in 65 patients (mean age = 10.3 years, 41 males). The majority of cardiopathies were single ventricles (SV) with (49% of patients) or without (26%) tricuspid atresia. A palliative bidirectional cavo-pulmonary (BCP) anastomosis was performed prior to Fontan in 15 patients. Intra-atrial Fontan tunnelling was performed in 43 patients, Kreutzer-type operations in 10, and extracardiac tubes were used in 8 patients. The mean duration of follow-up was 6.1 +/- 0.3 years. RESULT The 30-day mortality was 13.8%. Early mortality was higher among patients with SV with than without tricuspid atresia (P < 0.01), and among patients < 4 years old. Early reoperations were required in 5 patients, including dismounting in 1, BCP anastomosis after Kreutzer procedure in 1, and tube thrombosis in 1 patient. A single death occurred past 30 days, and late adverse events included protein-losing enteropathy in 1 patient, complete atrioventricular block in 1, and tube thrombosis treated with heparin in 2 patients. At the end of follow-up, 75% were in New York Heart Association functional class I. CONCLUSION Our intermediate-term results of Fontan-type operations were satisfactory, and steadily improving. The prognosis was better in patients operated at age 4 or older. A prior BCP anastomosis improved the results. A higher morbidity was observed with intra- than with extra-atrial Fontan procedures. The merit of fenestration procedures with respect to morbidity remains the be evaluated.

Abstract
Using (13)C-NMR, methyl-beta-D-glucopyranoside (MeG) was characterized as a major compound in the leaves of the alpine herb Geum montanum L. MeG continuously accumulated during the life span of G. montanum leaves, and accounted for up to 20% of the soluble carbohydrates in aged overwintering leaves, without being reallocated during senescence. Incubating intact plant tissues, culture cells, and purified organelles with (13)C-labelled substrates showed that MeG was synthesized in the cytosol of cells, directly from glucose and methanol molecules. There was no contribution of the C-1 pathway. MeG was subsequently stored in the vacuole without being re-exported to the cytoplasm. All the dicots tested contained the enzymatic machinery permitting MeG synthesis from methanol and glucose, but the plants accumulating this compound at concentrations higher than 1 micromol g(-1) wet wt were mainly members of the Rosaceae family belonging to the Rosoideae subfamily. It is suggested that the synthesis of MeG may contribute to reduce the accumulation in the cytoplasm of methanol and its derived compounds.
