Abstract
The red cell allo-antibodies research is mandatory before transfusion. In France, pretransfusion testing intervals that are prescribed by regulatory and accrediting agencies are commonly 72hours. In the University hospital of Brest, the interval for multi-transfused patients has been 24hours. In this study we aim to analyse these practice and argue the delay. METHODS This is a retrospective study of post-transfusional allo-immunizations from 2015 to 2020. For each patient, the time interval between the last negative research and the allo-immunization was investigated. RESULTS 189 patients developed allo-antibodies. In 16 patients (8,5%), the interval for allo-immunization was 24hours, 48hours and 72hours in 4, 8 and 4 patients respectively. 12 patients were transfused after the discovery of the allo-antibodies. That means if we have chosen a delay of validity of 72hours, then 9 patients would have been transfused with a negative result. CONCLUSION Checking for allo-antibodies before RBC transfusion with an interval of 24hours (and not 72hours) is pertinent in order to assure an optimal transfusion safety and to limit the risk of hemolytic transfusion reactions. A pretransfusion testing interval of 24hours for multi-transfused patients should be considered.

Abstract
Abstract
Background
Embolic event is one of the complications of VT ablation. This may be due to the presence of intra-cardiac thrombus before ablation. However, there is no clear consensus on how to rule out thrombus before the procedure.
Objective
We sought to examine the prevalence and risk factors of intra-cardiac thrombus with cardiac computed tomographic (CT) scan in patients undergoing scar-related VT ablation.
Methods
In absence of contra-indication, all patients undergoing scar-related VT ablation at our institution underwent contrast-enhanced cardiac CT within one week before ablation. 324 consecutive patients (292 male, 59±16 yo) have been included in this study. The etiology was ischemic cardiomyopathy (CMP) (n=191), arrhythmogenic right ventricular CMP (ARVC) (n=37), congenital CMP (n=11) or other CMP (n=85). LVEF was <40% in 154 patients (48%).
Results
Intra-cardiac thrombus was diagnosed in 29 (9%) patients: in the left atrium (n=8), in the right atrium (n=1), in the left ventricle (n=15), in the right ventricle (n=3), in right and left atrium (n=1), and in left atrium and right ventricle (n=1). Moreover in 2, a bilateral pulmonary embolism was identified. The population with thrombus was older (65±12 vs 58±16 years, p=0,005), with more permanent atrial fibrillation (AF) (28% vs 8%; p=0.005). Patients with left ventricular (LV) aneurysm were at higher risk of thrombus 50% vs 3% (p<0.001). The average CHADSVASC score was similar for both groups (2,5 vs 2,1; p=0.179). After matching for age and sex, only ischemic CMP and LV aneurysm were risk factors for thrombus. Because of arrhythmic storm, ablation was performed by epicardial approach only, in 5 patients with intra-ventricular thrombus and by retroaortic approach only, in 2 patients with LAA thrombus. No embolic event occurred during these procedures.
Conclusion
CT scans help eliminating intra-cardiac thrombus before VT ablation procedure. A high proportion of thrombus (9%) was identified. Whereas LV thrombus should systematically be ruled out before scar related VT ablation, in patients with AF, a LAA thrombus should also be eliminated as well as RV thrombus in patients with ARVC.

Abstract
Biofilms can be formed on the surfaces of dairy processing equipment and are a potential source of product contamination. This study evaluated the diversity of multispecies biofilms formed on stainless steel (SS) due to the contaminating microbiota in raw milk. Samples of raw milk were used: one was fresh milk and the other maintained in refrigerated bulk tanks for up to 48 h. The mesophilic aerobic contamination was ∼104 CFU ml-1 in fresh milk and 106 CFU ml-1 in bulk milk. SS coupons were kept immersed in the milk at 7 ±2 °C for 10 days, and every two days, the raw milk was changed for samples of the same origin collected on the current day. After incubation for 10 days, sessile cells in the biofilm reached 105 CFU cm-2 in the presence of fresh milk, and 106 CFU cm-2 in the presence of bulk milk. The genetic diversity analysis showed that Gammaproteobacteria and Bacilli predominated in the biofilms throughout the incubation of both milk samples and these biofilms showed a reduction in diversity over time. The main classes of bacteria found in these biofilms have representatives of great importance since many of them have spoilage potential.

Abstract
e13550 Background: Leptomeningeal metastasis (LM) are reported in 5-25% of patients with melanoma. However, only very few large contemporary cohorts of melanoma patients with LM have been published. Methods: We report on a case series of 28 consecutive patients with LM from melanoma (BRAF mutated in 14 cases, of 19 tested) diagnosed between April 2007 and April 2016, and treated for LM using a combination of systemic treatment, intra-cerebrospinal fluid (CSF) therapy and radiotherapy according to prior treatments and the presentation of LM. Results: The median age at LM diagnosis was 49.5 years (range 27-73). Median ECOG-performance status was 2 (0-4). Concomitant brain metastases were present in all but 4 patients at LM diagnosis. LM was the first site of metastatic disease for only 2 patients. Median time from melanoma diagnosis to LM diagnosis was 0.33 years in patients with metastatic disease at melanoma diagnosis (4 patients) and 4.5 years in patients without metastatic disease at melanoma diagnosis (24 patients). First line treatment for LM was a combination of intra-CSF (liposomal cytarabine) and systemic treatments in 25 cases, and systemic treatment alone in 3 cases. Systemic treatments include chemotherapy (n = 18), targeted therapy (BRAF inhibitor n = 9; MEK inhibitor, n = 3) and immunotherapy (n = 4). No radiotherapy was performed. Ten patients received more than one line of treatment for LM. Median progression-free survival with first line treatment was 1.75 months. Responses or stabilization (for at least 2 months) were observed in only 7 patients. Median overall survival (OS) for the whole cohort was 3.08 months. Conclusions: The prognosis of patients with LM from melanoma remains poor. The role of new agents such as targeted therapies and immunotherapy for the treatment of LM is still not well defined. Adequate use of intrathecal chemotherapy, targeted therapy and immunotherapy could improve the survival of these patients.

Abstract
Prostate cancer is the first cancer and the second cause of cancer death in men in France. It is now a major public health issue, particularly given the increase of life expectancy. If screening is based on blood PSA and clinical examination (DRE), diagnosis requires the histological analysis of prostate samples. In current clinical routine, these biopsies are performed by endorectal through ultrasound guidance. In most cases, the cancer is not visible in the ultrasound image and the latter is used to make a dozen samples (or core), distributed as best as possible in the prostate. To increase the accuracy and the contribution of these biopsies, the use of data acquired by the magnetic resonance imaging (MRI), as well as the fusion of ultrasound and MRI images, is a therapeutic undergoing validation, and today performed in many institutions with dedicated tools. The objective of this work is to present the practical arrangements for the implementation of these biopsies using the image fusion, and discuss the advantages and benefits.

Abstract
AIMS To assess the biodistribution of bone marrow mononuclear cells (BMMNC) delivered by different routes in patients with subacute middle cerebral artery ischemic stroke. PATIENTS & METHODS This was a nonrandomized, open-label Phase I clinical trial. After bone marrow harvesting, BMMNCs were labeled with technetium-99m and intra-arterially or intravenously delivered together with the unlabeled cells. Scintigraphies were carried out at 2 and 24 h after cell transplantation. Clinical follow-up was continued for 6 months. RESULTS Twelve patients were included, between 19 and 89 days after stroke, and received 1-5 × 10(8) BMMNCs. The intra-arterial group had greater radioactive counts in the liver and spleen and lower counts in the lungs at 2 and 24 h, while in the brain they were low and similar for both routes. CONCLUSION BMMNC labeling with technetium-99m allowed imaging for up to 24 h after intra-arterial or intravenous injection in stroke patients.

Abstract
BACKGROUND/AIM Prolonged overall survival (OS) has been reported for selected patients with leptomeningeal metastases (LM). The management and treatment of such patients is poorly-described. We report our experience on breast cancer (BC)-associated LM and patients with prolonged survival. PATIENTS AND METHODS Eleven patients with BC and LM had an OS >12 months in which treatment is described. RESULTS Combined intra-cerebro spinal fluid (CSF) and systemic treatment were administered until disease progression or toxicity in all but two patients. Involved-field radiotherapy was administered to two patients. Median OS in this selected cohort following LM diagnosis, was 21.0 (range=13-33.3) months. CONCLUSION Prolonged OS but also prolonged responses can be observed in BC with LM. An individualized and multi-disciplinary approach is advised for the management of these patients.

Abstract
2070 Background: Around 5% of patients with breast cancers (BC) will develop leptomeningeal metastasis (LM). The incidence may increase. Methods: We reported the description and outcome of 112 consecutive BC patients diagnosed with LM in our institution from 2007 to 2011. Correlations between characteristics and overall survival (OS) were analyzed using usual statistical methods (Kaplan Meier, Log-rank, Cox model). Results: BC were invasive ductal carcinoma in 69.7%. Estrogen and progesterone receptors were detected in respectively 61.6 and 44.6%. HER2 expression was observed in 26%. 23% were triple negative. Median time between BC diagnosis and LM diagnosis was 44 months. At LM diagnosis, median age was 54 and median Performance Status (PS) was 2. CSF cytology and cerebrospinal MRI were positive in respectively 72,5% and 87%. 103 (92%) LM patients received IT liposomal cytarabine as 1st line of treatment (ventricular device in 47%). IT therapy could be associated with systemic treatment in 58% of the cases and cerebral radiotherapy for LM in 14% of the cases. Clinical response after 1st line treatment was observed in 57%, CSF response in 30,5%, MRI response in 62,5%. 24 patients received a 2nd line of IT thiotepa, 6 a 3rd line of IT methotrexate. The more significant prognostic factors (p<0,0001) were initial PS, associated systemic treatment and triple negative BC status. Other significant predictors of OS were thiotepa as 2nd line treatment (p=0,0004), intracranial hypertension at LM diagnosis (p=0,019), associated cerebral radiotherapy (p=0,02), progesterone receptor status (p=0,04). Median OS of the 103 treated patients was 3,8 months (4,75 months for 0-2 PS and 1,6 months for 3-4 PS patients). Conclusions: Median OS was consistent those of other recent cohorts of BC LM. Our results confirm the role of a very early diagnosis, before the degradation of the general status. The association with systemic treatment or cerebral radiotherapy is indicated when possible.

Abstract
The interaction of a series of steroid hormones (DHEA, progesterone, testosterone, estradiol) with serum albumin immobilized on porous silica particles and the effect of reactive oxygen species and nitric oxide on this interaction were studied using a biochromatographic approach. The determination of enthalpy and entropy changes of this binding indicated that van der Waals interactions and hydrogen bonds predominated the hormone association with albumin. Reactive oxygen species (H(2)O(2) and OH*) increased the hormone binding affinity to albumin. On the other hand, this binding was decreased with the presence of NO*. This variation was due to conformational changes in the binding region explained by the oxidation of some residues such as free thiol and arginine. The thermodynamic analysis showed that free radical affects the van der Waals forces and/or a hydrogen bond of the hormone binding with albumin. These results explained the role of reactive oxygen species and nitric oxide in the hormone free fraction level in the blood.

Abstract
Following Beatson's publications in 1896, various modalities of endocrine therapy applied to breast cancer have been developed. Endocrine treatment has greatly contributed to the improvement of the disease's prognosis. Tamoxifen has established itself as a first choice adjuvant therapy for patients with tumors expressing hormone receptors. Over the last decade, third generation aromatase inhibitors have demonstrated their efficacy amongst menopausal patients, alone or in combination with tamoxifen. Efficacy of these medications is dependent on patient's compliance. This article proposes a synthesis of the main knowledges available in the field of breast cancer endocrine therapy.

Abstract
Breast cancer mortality is decreasing, partly due to better adjuvant treatments with new drugs and new schedules. In Belgium, the overall survival is 76%. Chemotherapy is still an important treatment option. We need to better select patients who really will benefit from treatment in order to decrease toxicity and improve long term outcome.Targeting the specific population is now a priority. Prognostic and predictive factors will enable us to better define the sub-population of patients most benefiting from treatment. We will also discuss the knowledge of systemic treatment. When we have to decide wether chemotherapy is indicated, we need to well balance the treatment risks and benefits because gain in survival is important but reducing short and long term toxicity is also a challenge.

Abstract
Adjuvant radiotherapy after surgery is a ("well-established standard" in routine clinical practice for breast cancer. Nevertheless, a variety of questions still remain unanswered. We intend to illustrate the overall importance of radiotherapy in breast cancer and highlight some unresolved questions by quoting presentations recently made at ASTRO-2010. More and more emphasis is put on the idea of an individual approach. Predicting the individual local recurrence risk is the search for the "Holy Grail". Methods such as nomograms and genomic profiling are currently tested but need to be validated before their widespread clinical application.

Abstract
This study reports a consecutive serie of 427 breast neoplasms (411 patients) diagnosed and treated in our department between 1994 and 2004. Patients' records were prospectively collected including personnal medical history and the major elements of the diagnostic and the therapeutic protocol applied. 12 patients (3%) had to be excluded due to incomplete follow-up data. With a median follow-up of 8 years, a 4.5% loco-regional relapse rate is noted while 11% of patients recurred at distant sites and 9% died of their disease progression. These statistics are comparable to those published by prominant breast cancer centers. Amongst the 16% of deaths (67/411 Pts), 54% are due to breast cancer progression. The results are discussed with the aim to upgrade the diagnostic and the therapeutic protocols offered to our patients.

Abstract
INTRODUCTION Intraoperative molecular assay Gene Search BLN Assay (BLN) detects sentinel lymph node (SLN) metastasis in breast cancer. Our objective was to compare BLN to the definitive conventional histologic methods and to experiment the management of BLN in routine. MATERIAL AND METHODS Each SLN was cut into alternate slabs. Half slabs were analysed with the intraoperative BLN molecular method, and the other slabs with the definitive histologic method. RESULTS Two hundred and thirty four SLN have been analysed (124 patients). Thirty-five SLN had metastasis for 29 patients (23.4%). BLN correctly identified 28 patients. Two cases of discordance between BLN and standard method were found, probably explained by a sample bias. The sensibility of BLN is 96.4%, the sensitivity is 99%, the predictive positive value is 96.4%, the predictive negative value is 99% and the concordance is 98.4%. The surgery time increases and there is a need to adapt the theatre organization accordingly. CONCLUSION The Gene Search BLN Assay gives a great interest for the patient, the surgeon and the pathologist because it increases the quality of the intraoperative analysis by comparison with the intraoperative conventional histology.

Abstract
BACKGROUND Erythema elevatum diutinum (EED) is a very rare form of chronic dermatosis clinically characterised by reddish-violet papular nodules extending to the surfaces of the limbs and extremities. Histologically, there are classically two phases of progression initially involving associated neutrophilic dermatosis and leucocytoclastic vasculitis, which is later followed by fibrosis of characteristic appearance. We report the association of EED and pyoderma gangrenosum in a patient infected with HIV. PATIENTS AND METHODS A 53-year-old male seen since 1989 for HIV infection had been presenting firm bilateral and symmetrical nodules on the feet for 6 months. Histological analysis of one of these nodules resulted in diagnosis of chronic erythema elevatum diutinum and treatment with dapsone was initiated. Three months later, despite regression of the EED lesions under dapsone, two large pustules appeared on the outer aspect of the right leg; they were confluent and progressed towards a superficial ulcer with rounded edges with a clinical appearance evocative of pyoderma gangrenosum (PG). Histopathological analysis demonstrated a massive dermal infiltrate beneath the ulcer comprising neutrophils with evidence of leucocytoclasia, all of which militated in favour of the diagnosis of pyoderma gangrenosum. DISCUSSION We report for the first time the association of two forms of neutrophilic dermatosis, EED and PG, in an HIV-positive patient. This case report and certain data in the literature suggest that the various forms of neutrophilic dermatosis tend to result in a range of lesions rather than in clearly distinct entities.

Abstract
Cell-based treatments have been considered a promising therapy for neurological diseases. However, currently there are no clinically available methods to monitor whether the transplanted cells reach and remain in the brain. In this study we investigated the feasibility of detecting the distribution and homing of autologous bone-marrow mononuclear cells (BMMCs) labeled with Technetium-99 m ((99m)Tc) in a cell-based therapy clinical study for chronic ischemic stroke. Six male patients (ages 24-65 years) with ischemic cerebral infarcts within the middle cerebral artery (MCA) between 59 and 82 days were included. Cell dose ranged from 1.25x10(8) to 5x10(8). Approximately 2x10(7) cells were labeled with (99m)Tc and intra-arterially delivered together with the unlabeled cells via a catheter navigated to the MCA. None of the patients showed any complications on the 120-day follow-up. Whole body scintigraphies indicated cell homing in the brain of all patients at 2 h, while the remaining uptake was mainly distributed to liver, lungs, spleen, kidneys and bladder. Moreover, quantification of uptake in Single-Photon Emission Computed Tomography (SPECT) at 2 h showed preferential accumulation of radioactivity in the hemisphere affected by the ischemic infarct in all patients. However, at 24 h homing could only distinguished in the brains of 2 patients, while in all patients uptake was still seen in the other organs. Taken together, these results indicate that labeling of BMMCs with (99m)Tc is a safe and feasible technique that allows monitoring the migration and engraftment of intra-arterially transplanted cells for at least 24 h.

Abstract
BACKGROUND A single-centre, randomized, double-blind, placebo-controlled study. AIMS To compare the safety and tolerability of four different sublingual immunotherapy (SLIT) regimes in grass pollen allergic rhinitis. METHODS Thirty subjects sensitized to grass pollen were enrolled and allocated to four groups. Sublingual immunotherapy was administered in tablets daily for 10 days. Groups 1 and 2 received incremental sublingual doses of 100, 200, 300, 400 and 500 IR, Group 1 daily and Group 2 increments every second day. Repeated constant dose regimens of 300 IR and 500 IR were administered in Groups 3 and 4 respectively. Safety assessments included adverse events (AE), vital signs, electrocardiogram (ECG) and clinical laboratory tests. RESULTS Sublingual immunotherapy 300 IR (Group 3) administered in a constant dose and incremental doses up to 500 IR (Groups 1 and 2) were generally well tolerated. The majority of AEs were mild to moderate, the most common being oral pruritus, throat irritation and swollen tongue. Severe local AEs (swelling of throat) were observed only for Group 4. No serious systemic AEs were reported. There were no relevant changes in clinical laboratory, vital signs and ECG data. CONCLUSION Adverse events were mostly local (sublingual), were not severe and resolved rapidly. Using a 5-day induction regimen high-dose treatment up to 500 IR could be administered without important side-effects, in contrast to initiating with a constant dose of 500 IR. The data indicate that a short dose increase phase may reduce the incidence of AEs when high-dose SLIT is administered.

Abstract
According to international criteria, autoimmune hepatitis (AIH) type 1 is characterized by the presence of antinuclear or anti-smooth muscle antibodies (SMA) with F-actin specificity. SMA have been found in 85% of AIH patients, but are not specific to this disease, and anti-F-actin specificity is not always verified when SMA are detected. The objective of this study was to determine the diagnostic value of anti-F-actin antibodies in a large population. A multicenter study involving 12 clinical centers was performed. Patients were selected on the basis of the presence of F-actin SMA detected by indirect immunofluorescence (IIF) on rat liver-kidney-stomach sections and was confirmed by IIF on Hep2 cells treated with colchicine, or F-actin dot-blot. The clinical status of patients was determined from their medical records. One hundred sixty-eight patients were included: 76% women, 24% men; mean age of 45 years (range, 2-88 years), with a bimodal age distribution. Sixty percent had AIH type 1, and 40% had another disease. In the group of women younger than 25 years, 90% had AIH type 1. Other pathologies associated with antiactin were other liver diseases (19%), including viral hepatitis C (7%), and non-liver diseases (21%), including connective tissue diseases (12%). Antibody titers were higher in AIH than in other diseases. Antiactin antibodies are of major diagnostic value in AIH, especially in young women; they may be found in other disease settings, but mostly at low levels.

Abstract
BACKGROUND The efficacy and safety of sublingual immunotherapy (SLIT) in patients with chronic rhinitis related to sensitization to house dust mites are still controversial. METHODS After application of an anti-mite mattress cover, patients were only included in the study when the cumulative symptom score over a fortnight was greater than 70 out of a possible total of 168. Thirty-two of the 120 patients selected were randomized to receive SLIT for 2 years: 17 received placebo and 15 received the Dermatophagoides pteronyssinus and D. farinae 50/50 allergen extract. RESULTS Significant between-group differences were observed after 1 year and persisted at the end of the second year for the rhinitis total score (P < 0.02), blocked nose score (P < 0.01) and nasal itching score (P < 0.01). Skin reactivity to house dust mites was significantly reduced in the group receiving house dust mite extract (P < 0.03). No statistical difference was observed between the two groups for medication scores, but a low medication consumption was observed in all patients. No serious and no systemic adverse reactions were reported. CONCLUSION This study indicates the superiority of active treatment vs. placebo, evaluated on efficacy criteria (rhinitis score) or objective criteria (skin reactivity). The availability of a solid form (tablet) could represent a progress in terms of patient acceptability.
