Abstract
BACKGROUND AND OBJECTIVE Traditionally, the diagnosis of acute rejection (AR) relies on invasive transbronchial biopsies (TBBs) to obtain histopathological samples. We aimed to evaluate the diagnostic yield of probe-based confocal laser endomicroscopy (pCLE) as a complementary and non-invasive tool for ACR screening, comparing its results with those obtained from TBBs. METHODS Between January 2015 and April 2022, we conducted a retrospective study of all lung transplant recipients aged over 18 years at Toulouse University Hospital (France). All patients who underwent bronchoscopies with both TBBs and pCLE imaging were included. Two experienced interpreters (TV and MS) reviewed the pCLE images independently, blinded to all clinical information and pathology results. RESULTS From 120 procedures in 85 patients, 34 abnormal histological samples were identified. Probe-based confocal laser endomicroscopy revealed significant associations between both alveolar (ALC) and perivascular (PVC) cellularities and abnormal histological samples (p<0.0001 and 0.003 respectively). Alveolar cellularity demonstrated a sensitivity (Se) of 85.3 %, specificity (Spe) of 43 %, positive predictive value (PPV) of 37.2 % and negative predictive value (NPV) of 88.1 %. For PVC, Se was 70.6 %, Spe 80.2 %, PPV 58.5 % and NPV 87.3 %. Intra-interpreter correlation (TV) was 88.3 % for the number of vessels (+/-1), 98.3 % for ALC and 90 % for PVC. Inter-interpreter correlation (TV and MS) was 80 % for vessels (+/-1), 97.5 % for ALC and 83.3 % for PVC. CONCLUSION Our study demonstrates the feasibility of incorporating pCLE into clinical practice, demonstrating good diagnostic yield and reproducible outcomes in the screening of AR in lung transplant recipients.

Abstract
Hypervirulent Klebsiella pneumoniae (hvKp) raised concern worldwide. We studied 22 hvKp clinical invasive isolates referred to the Belgian national reference laboratory between 2014 and 2020. Sixty-four percent of the isolates expressed K2 capsular serotype and belonged to 7 different MLST lineages, while 32% expressed K1 (all belonging to ST23) and were associated with liver abscesses. Primary extra-hepatic infections were reported in 36% and sepsis for 95% of the patients with 30% of deaths. Improved clinical and microbiological diagnostics are required as hvKp may represent an underestimated cause of community-acquired invasive infections in Belgium.

Abstract
BACKGROUND Mastocytosis is characterized by the accumulation/proliferation of abnormal mast cells. The frequency of isolated cutaneous involvement in adults with mastocytosis has not been fully determined. The main objective of our study was to assess the frequency of isolated cutaneous mastocytosis (CM) in adults with mastocytosis skin lesions. The second objective was to compare the clinical, histological, biological and imaging features in patients with isolated CM and patients with systemic mastocytosis (SM). METHODS We included all patients with histology-proven mastocytosis skin lesions between January 2009 and December 2017. The mastocytosis diagnosis was made according to the international diagnostic criteria. All data were collected from a dedicated specific case report. RESULTS Among 160 patients with mastocytosis skin lesions, 25 patients had isolated CM (15.6%), 105 had SM and 30 (18.7%) patients had undetermined mastocytosis. Skin KIT mutation (OR: 51.9, 95% CI: 3.9-678, P = 0.001) and high bone marrow tryptase (OR: 97.4, 95% CI: 10.3-915, P = 0.001) were strong predictors of SM. The prevalence of osteoporosis was higher in the SM population than in the isolated CM population. Moreover, a decrease in bone mineral density over a short period of follow-up (1-2 years) was associated with SM. There were no differences between the two groups regarding the frequency of mast cell activation symptoms, the presentation of skin lesions, the number of mast cells in the dermis and the level of serum tryptase. We propose considering the KIT mutation status and bone marrow tryptase levels to aid the diagnosis of isolated CM in adult mastocytosis patients. CONCLUSION Only a small minority of adults with mastocytosis skin lesions has isolated cutaneous involvement. In 18.7% of mastocytosis cases, even complete workup does not allow for a precise classification of patients.

Abstract
OBJECTIVE OF THE STUDY To test whether a direct-on-site microscopic examination of fresh, unstained puncture slides by the radiologist decreases the rate of false-negative cases on ultrasound-guided fine-needle cytology of parotid gland masses. PATIENTS Thirty parotid gland masses from 28 patients were punctured under ultrasound guidance. The same group was used as its control group. METHODS After one or two passes, the material was spread on slides and air-dried (control group, without microscopic examination). For the study group, it was thus analyzed unstained under the microscope. A sample was considered adequate if at least six clusters of parotid cells were found per slide on at least two slides. For the study group, new punctures were obtained and slides prepared until this condition was fulfilled. RESULTS Of the 30 evaluated masses, 100% benefited from a cytological diagnosis after microscopy. Twenty-four were adequate in the control group, while 30 were adequate in the study group. The maximum number of punctures to obtain an adequate sample was six. On-site direct microscopy significantly increased the number of adequate specimens by 20% (P=0.03, CI [1.63-20%]). CONCLUSION Direct and systematic examination of slides by a radiologist avoided the risk of false-negative results caused by having insufficient sample material.

Abstract
Twenty-four patients presenting an acute stroke with watershed cerebral infarct on CT scan or MRI were included in this retrospective study. Age was 63 +/- 14 years (mean +/- SD), and sex ratio was 2 men for 1 woman. Main clinical features were: in anterior location, lower limb weakness and frontal syndrome with transcortical motor aphasia in left lesions or spatial dyscalculia in right ones; in posterior location, brachiofacial weakness with constant quadranopsia and hypoesthesia, and Gerstmann syndrome in left lesion. There was no distinctive feature for subcortical and multiple infarcts. In bilateral infarcts, there were one pseudobulbar syndrome, and 2 pseudo brainstem syndromes with neuropsychological signs. Aetiologies were severe carotid artery disease in 14 cases, severe cardiopathy in 6, isolated cerebral angiitis in 1, essential thrombocythemia in 1, protein C deficiency with sickle cell disease in 1, and cholesterol emboli in 1 anatomical case. CBF performed in carotid artery occlusions or tight stenoses showed evidence of haemodynamic changes. Microembolic process can be proposed in the case with cholesterol emboli. Preventive treatment is discussed.

Abstract
OBJECTIVE The presence of atypical cells in urine cytology is unsatisfactory for both cytologists and clinicians. The objective of this study was to test whether p53 and Ki-67 immunostaining could improve urothelial carcinoma (UC) detection on urinary cytology. METHODS A total of 196 urine samples were analysed, 142 from the bladder, 41 from the upper tract and 13 from ileal bladder replacement. Cytology results were expressed as normal (N) (n = 81), atypia cannot exclude low-grade UC (ALG) (n = 25), suspicious for high-grade UC (SHG) (n = 39) and high-grade UC (HG) (n = 51). Actual diagnoses were confirmed by histopathological analysis, cystoscopic examination or follow-up for at least 1 year. Immunocytochemistry performed on CytoSpin™ slides allowed the determination of the percentage of positive cells with p53 and Ki-67. RESULTS The median percentage values [first to third quartile] of p53 and Ki-67 were 0 [0-5] and 0 [0-1] for N cytology, 5 [0-40] and 2 [1-10] for ALG, 10 [0-30] and 6 [3-25] for SHG, and 30 [10-80] and 20 [10-30] for HG, respectively. Statistically higher values were observed for both tests (P < 0.001) in positive cytologies (ALG, SHG and HG). The optimal cut-offs were 5% for p53 and 3% for Ki-67. The sensitivity and specificity for the detection of all UC were 86.4% and 76.7% for cytology alone, 81.3% and 93.2% for cytology and p53, 75.7% and 88% for cytology and Ki-67, and 68.9% and 97.5% for cytology, p53 and Ki-67, respectively. CONCLUSION Using p53 and/or Ki-67 in addition to cytology increases the specificity without penalising the sensitivity.

Abstract
INTRODUCTION Interventional cardiology procedures are regularly exposed to ischemic neurological complications. IV fibrinolysis is the only approved treatment in ischemic stroke but is very often contraindicated in these situations. Many techniques of interventional neuroradiology (mechanical thrombectomy) have been developed over the past years and are used to treat these patients. OBSERVATION We report the case of two patients who were admitted in emergency for ischemic stroke with contraindication to IV fibrinolysis (cardioversion for atrial fibrillation under anticoagulation; 24 hours after carotid surgery). These patients were treated by endovascular thrombectomy procedure. DISCUSSION After validation of IV fibrinolysis within 4.5 hours after stroke onset, techniques of mechanical thrombectomy have gradually been developed, either as a complementary treatment or as an alternative in the case of CI to fibrinolysis. These endovascular thrombectomy devices currently allow recanalization of proximal cerebral occlusions, which correlates with a favorable clinical prognosis. A review of the literature is provided, along with a discussion about the techniques currently being improved, their advantages and disadvantages and the selection of patients that can benefit from endovascular procedures. CONCLUSION In the case of a sudden occurrence of a neurological deficit during a cardiovascular procedure, a "thrombolysis alert" should be triggered. This will permit the rapid establishment of a clinico-radiological report for selecting stroke patients eligible for a procedure of recanalization by thrombolysis and/or mechanical thrombectomy.

Abstract
BACKGROUND Liver metastases (LM) in close contact to hepatic veins (HV) are a frequent cause of unresectability. Reconstruction of hepatic veins is technically difficult and outcomes are poor. Intra-operative radiofrequency ablation (IRFA) with vascular exclusion (VE) may be a useful approach. METHODS Out of 358 patients operated for LM, 22 with LM close to a HV treated by IRFA under VE with at least one year of follow-up were included in this retrospective study. Technical success was evaluated at four months by CT scan of the ablated lesion. Complications; local, hepatic and extra-hepatic recurrence rates, and overall survival are reported. RESULTS The median number of metastases was 4.5 [range: 1-12]. Seventeen patients had bilateral metastases. The median size of ablated lesions was 2 cm [range: 1-5.5]. Seven complications occurred (1 Grade 1, 2 Grade 3b and 4 Grade IVa), with no mortality. No recurrence of ablated lesions was detected at four months or during follow-up. Seventeen patients had new or extra-hepatic lesions. Median overall survival for colorectal patients was 40 months 95%CI[17.5-not reached]. CONCLUSIONS IRFA plus VE for LM in close contact to a HV is a novel approach, appearing to be a safe and effective technique which can extend the applications of liver metastases surgery.

Abstract
Background
Despite neoadjuvant chemotherapy, few patients with colorectal cancer liver metastases (CRLM) are eligible for liver resection. The aim of the present study was to investigate the efficacy of intraoperative radiofrequency ablation (IRFA) in the treatment of unresectable CRLM.
Methods
Patients with unresectable metastases confined to the liver were eligible for this prospective, multicentre phase II study conducted between 2003 and 2008. They received IRFA treatment either with or without parenchymal resection, and underwent clinical and pathological examinations. The primary endpoint was complete hepatic response at 3 months. Overall, event-free and local progression-free survival, morbidity and quality of life were also examined.
Results
Fifty-two patients were included, all of whom received neoadjuvant chemotherapy. They had a median of 5 (range 1–13) metastases, mostly bilateral or recurrent. A complete hepatic response was observed in 39 patients (75 (95 per cent confidence interval (c.i.) 61 to 86) per cent). Of ten patients with hepatic recurrence at 3 months, two relapses were at the site of ablation. Median follow-up was 2·9 (95 per cent c.i. 2·5 to 3·6) years. The 1-year local progression-free survival rate was 46 (95 per cent c.i. 32 to 59) per cent, the 3-year event-free survival rate was 10 (95 per cent c.i. 4 to 21) per cent and the 5-year overall survival rate was 43 (95 per cent c.i. 21 to 64) per cent. Twenty patients had postoperative complications, including one death. Quality of life increased over time for patients without disease progression.
Conclusion
IRFA, either with or without resection, is a promising treatment option for patients with unresectable CRLM. Registration number: NTC00210106 (http://www.clinicaltrials.gov).

Abstract
We report on the first measurement of the triangular v3, quadrangular v4, and pentagonal v5 charged particle flow in Pb-Pb collisions at sqrt(s(NN)) = 2.76 TeV measured with the ALICE detector at the CERN Large Hadron Collider. We show that the triangular flow can be described in terms of the initial spatial anisotropy and its fluctuations, which provides strong constraints on its origin. In the most central events, where the elliptic flow v2 and v3 have similar magnitude, a double peaked structure in the two-particle azimuthal correlations is observed, which is often interpreted as a Mach cone response to fast partons. We show that this structure can be naturally explained from the measured anisotropic flow Fourier coefficients.

Abstract
The centrality dependence of the charged-particle multiplicity density at midrapidity in Pb-Pb collisions at sqrt[s_{NN}]=2.76 TeV is presented. The charged-particle density normalized per participating nucleon pair increases by about a factor of 2 from peripheral (70%-80%) to central (0%-5%) collisions. The centrality dependence is found to be similar to that observed at lower collision energies. The data are compared with models based on different mechanisms for particle production in nuclear collisions.

Abstract
We report the first measurement of charged particle elliptic flow in Pb-Pb collisions at sqrt[S(NN)] =2.76 TeV with the ALICE detector at the CERN Large Hadron Collider. The measurement is performed in the central pseudorapidity region (|η|<0.8) and transverse momentum range 0.2<p t<5.0 GeV/c. The elliptic flow signal v₂, measured using the 4-particle correlation method, averaged over transverse momentum and pseudorapidity is 0.087 ± 0.002(stat) ± 0.003(syst) in the 40%-50% centrality class. The differential elliptic flow v₂ p t reaches a maximum of 0.2 near p t =3 GeV/c. Compared to RHIC Au-Au collisions at sqrt[S(NN)] 200 GeV, the elliptic flow increases by about 30%. Some hydrodynamic model predictions which include viscous corrections are in agreement with the observed increase.

Abstract
The first measurement of the charged-particle multiplicity density at midrapidity in Pb-Pb collisions at a center-of-mass energy per nucleon pair √ S NN = 2.76 TeV is presented. For an event sample corresponding to the most central 5% of the hadronic cross section, the pseudorapidity density of primary charged particles at midrapidity is 1584 ± 4(stat) ± 76(syst), which corresponds to 8.3 ± 0.4(syst) per participating nucleon pair. This represents an increase of about a factor 1.9 relative to pp collisions at similar collision energies, and about a factor 2.2 to central Au-Au collisions at √ S NN = 2.76 TeV. This measurement provides the first experimental constraint for models of nucleus-nucleus collisions at LHC energies.

Abstract
The ratio of the yields of antiprotons to protons in pp collisions has been measured by the ALICE experiment at sqrt[s]=0.9 and 7 TeV during the initial running periods of the Large Hadron Collider. The measurement covers the transverse momentum interval 0.45<p_{t}<1.05 GeV/c and rapidity |y|<0.5. The ratio is measured to be R_{|y|<0.5}=0.957±0.006(stat)±0.014(syst) at 0.9 TeV and R_{|y|<0.5}=0.991±0.005(stat)±0.014(syst) at 7 TeV and it is independent of both rapidity and transverse momentum. The results are consistent with the conventional model of baryon-number transport and set stringent limits on any additional contributions to baryon-number transfer over very large rapidity intervals in pp collisions.

Abstract
BACKGROUND AND STUDY AIMS Transjugular intrahepatic portosystemic shunt (TIPS) is an accepted interventional technique to treat refractory ascites in cirrhotic patients with severe portal hypertension. The expanded-polytetrafluoroethylene (e-PTFE) covered stent-graft (cs-TIPS) gives a better shunt patency rate than uncovered stents (ncs-TIPS). Our aim was to retrospectively evaluate whether cs-TIPS indeed improves refractory ascites and overall survival in a more effective way than ncs-TIPS in patients with cirrhosis. PATIENTS AND METHODS From 1992 to 2006, 222 cirrhotic patients with refractory ascites underwent a TIPS-procedure. In 126 patients a ncs-TIPS was inserted, in the remaining 96 patients a csTIPS was inserted. Liver transplantation and/or death were the end points of the follow-up. RESULTS The baseline characteristics of both groups were similar: age (55 +/- 11 years, ncs-TIPS/56 +/- 10 years, cs-TIPS), alcoholic cirrhosis (73% ncs-TIPS/80% cs-TIPS), Child-Pugh (9 +/- 2.0 ncs-TIPS/9.2 +/- 1.3 cs-TIPS) and MELD (15 +/- 6 ncs-TIPS/15 +/- 4.9 cs-TIPS), except that the bilirubin level was higher in the cs-TIPS group (2.5 +/- 2.7 mg/dL in cs-TIPS vs. 1.5 +/- 3.6 mg/dL in ncs-TIPS). One year shunt dysfunction occurred in 49% (n=63) of the ncs-TIPS vs. 19% (n = 18) of the cs-TIPS (P < 0.0001) and post TIPS encephalopathy in 56% (n=70) of the ncs-TIPS vs. 22% (n = 22) in the cs-TIPS group. Ascites control and overall survival were better in the cs-TIPS (P = 0.0071). The gain in survival in the cs-TIPS patients occurred especially in patients with a baseline MELD score <16 (P < 0.0001). Post TIPS encephalopathy and ncs-TIPS were independently related with poor survival (P < 0.0001, P = 0.0150; respectively). CONCLUSIONS In cirrhotic patients with refractory ascites cs-TIPS offers better symptomatic control of the ascites at one year follow-up and a better overall survival, especially in patients with a MELD score of <16 at baseline.

Abstract
In chronic liver disease, high circulating interleukin (IL)-6 contrasts with a poor acute phase response. We evaluated the impact of liver and circulating IL-6-receptor (IL-6R) forms on IL-6 bioactivity in chronic liver disease. IL-6, soluble IL-6-receptor and sgp130 levels were assayed in plasma from 45 patients with alcoholic liver disease, 84 with hepatitis C virus (HCV) infection undergoing transjugular liver biopsies and 15 healthy subjects. IL-6R mRNA was quantified on liver extracts from 54 patients with alcoholic liver disease with or without cirrhosis and 18 HCV-infected patients. The effect of gp130-Fc on fibrinogen secretion induced by IL-6 trans-signalling was evaluated on hepatocyte cultures. Levels of plasma IL-6 and sgp130, but not soluble IL-6R, increased with the stage of chronic liver disease, and correlated significantly with disease severity. Alcoholic liver disease patients had higher plasma IL-6 levels than hepatitis C, but lower liver IL-6R expression. In alcoholic and HCV-related liver diseases, liver IL-6R expression decreased with advanced fibrosis stage. In vitro, on hepatocytes, gp130-Fc blunted the acute phase response while soluble IL-6R enhanced IL-6 stimulation. In advanced chronic liver disease, high plasma IL-6 is associated with low liver IL-6R expression. This situation enables high plasma sgp130 to act as a major negative regulator of liver IL-6 trans-signalling, as demonstrated functionally here on hepatocytes. This might explain the poor acute phase response induced by IL-6 in chronic liver disease.

Abstract
4095 Background: Only few patients suffering from colorectal metastases (CRM) can have surgery and thus hope for a 40% 5-year survival rate. Adding IRFA to resection may improve the efficacy of surgery. Methods: The primary objective was to evaluate the efficacy of IRFA combined or not with resection in terms of 3-month complete hepatic response (CHR) in patients with unresectable CRM. Secondary endpoints were overall survival (OS), disease-free survival (DFS), morbidity and quality of life. A phase II study based on a Simon's two-stage design was conducted in 6 university French hospitals. Number of subjects estimated was 53, with 19 for the 1st stage. At the end of the 1st stage, 12 CHR were required to continue recruiting. At the end of 2nd stage, 37 CHR would be required to claim efficacy. Results: Fifteen of the first 19 patients exhibited CHR allowing the study to pursue accrual which ended in Nov 08; some patients are still followed up. As of Nov 08, data had been collected on 47 patients (mean age 61 years): 6 had RFA alone (13%), 37 had RFA and resections (82%), 2 could not be treated (4%). Median number of CRM was 5 (1–12). All had chemotherapy pre-op and 12 post-op (29%). Three-month data were available for 36 patients: 1 patient died on the 3rd week following intervention. Scans were available for 35 patients (independently reviewed). Of these, 29 had CHR (83%); 13 had 3-month morbidity (37%). The median follow-up was 15 months. One-year OS and DFS rates were 92.3% and 26% respectively. Analysis on all 53 patients will be communicated in June 09. Conclusions: These preliminary results suggest that IRFA combined or not to resection may be efficient in treating unresectable diseases despite their more aggressive pattern. This corroborates the EORTCC CLOCC Trial findings which demonstrated IRFA superiority upon chemotherapy alone. IRFA could thus be valuably associated to resection in treating patients with colorectal metastases that resection alone could not handle. No significant financial relationships to disclose.

Abstract
Vulvar cancer represents approximately 4% of all gynecologic malignancies and the most important prognosis factor in this cancer is the status of the regional lymph nodes. The radical inguinal lymphadenectomy, associated or not with radiotherapy, is accompanied by high morbidity, which can affect 50% of the patients. The sentinel node detection appears now to be feasible in patients with vulvar carcinoma, in order to reduce the morbidity of inguinal lymphadenectomy. But contrary to breast cancer, the learning curve is not easy to obtain because of the low number of cases. That is why we have described the procedure of selective lymphadenectomy. The aim of this technique is to remove the blue and/or marked inguinal lymph node and any other palpable lymph node, without a real radical inguinal lymphadenectomy. Thus, since November 2003, 4 procedures have been performed in total. With the lymphoscintigraphy, we identified 17 marked lymph node and we finally obtained 28 lymph nodes after surgery, with only one metastatic lymph node. There was no complication after our procedure. Selective lymphadenectomy appears to be a new procedure which may reduce the morbidity of usual inguinal lymphadenectomy.
