Composition, ζ Potential, and Molar Mass Distribution of 20 Must and Wine Colloids from Five Different Cultivars Obtained during Four Consecutive Vintages.

Colloids are responsible for undesirable haze formation in wine. Here, we characterized 20 colloid batches after isolation by ultrafiltration of musts and wines from five cultivars obtained from four consecutive vintages. Polysaccharide and protein concentrations of the colloids ranged from 0.10 to 0.65 and 0.03 to 0.40 mg/L, respectively. Protein profiling in must and wine colloids by fast protein liquid chromatography (FPLC) and liquid chromatography-high-resolution tandem mass spectrometry (LC-HR-MS/MS) analyses indicated a lower number of proteins in wine than in must colloids. Molar mass distribution analyses revealed all colloids to consist of two carbohydrate- (424-33,390 and 48-462 kg/mol) and one protein-rich (14-121 kg/mol) fractions. The observed barely negative ζ potentials (-3.1 to -1.1 mV) in unstable wines unraveled that colloid instability might be partly related to their poor electrostatic repulsion in the wine matrix. ζ potentials of the colloids from pH 1 to 10 are also presented. Our data support future developments to eliminate haze-forming colloids from wine.

Clinical Features and Survival of Multiple Primary Melanoma: A Belgian Single Center Cohort.

INTRODUCTION: It remains unclear whether multiple primary melanoma (MPM) patients have a worse survival prognosis compared with single primary melanoma (SPM) patients. OBJECTIVES: To investigate the demographics, histological features, and survival of MPM versus SPM patients. METHODS: Cox regression analyses compared survival between SPM and MPM patients. Furthermore, demographics and histological features of the MPM cohort were compared with the SPM patients retrieved from dermatopathology files between 2000 and 2019. RESULTS: Out of 3853 melanoma patients, 95 MPM patients were retrieved: 81 with two primary melanomas (85.2%) and 14.8% with three or more. Mean Breslow of the first melanoma was 0.84 mm [minimum (min): 0 mm, maximum (max): 16 mm, standard deviation (SD) 1.77] versus 0.37 mm (second MPM) (min: 0 mm, max: 2.5 mm, SD 0.50) and 0.33 mm (third MPM) (min: 0 mm, max: 0.6 mm, SD 0.22). The mean Breslow for the second MPM was significantly higher for men than women (0.59 mm versus 0.27 mm). First and second melanoma in MPM patients developed on preexisting melanocytic nevi in 13% and 12%, respectively. In contrast with the mean age of primary melanoma in Belgium for women (58.2 years) and men (63.3 years), MPM patients developed their first melanoma earlier, at 44.8 years and 54.6 years, respectively. The mean distribution of anatomical localization of primary and secondary melanoma was highly similar in women, whereas in men a shift towards lower extremities was observed (19% versus 28%). The thicker the primary melanoma was, the sooner the second appeared. Follow-up (2-4/year) versus (1/year) yielded a mean Breslow of 0.29 mm and 0.55 mm, respectively. Cox regression analysis with time-varying covariate revealed a tendency for a worse prognosis in 5-year survival rates, but this was not statistically significant (p = 0.09). Patient phenotypes were not available on the histological reports. CONCLUSION: A closer follow-up regimen of MPM versus SPM patients is probably justified.

[Impact of prolonged second stage of labor on perinatal morbidity : what is our experience ?] / Impact d'un second stade de travail prolongé sur la morbidité périnatale : quelle est notre expérience?

OBJECTIVE: the management of the second stage of labor and its optimal duration are controversial, particularly for nulliparous women. Our aim is to analyze the impact of a prolonged second stage on perinatal morbidity in our institution. MATERIAL AND METHODS: this is a retrospective study conducted in the University Hospital of Liège (Belgium) from January to July 2019. The 160 patients included were divided into two groups according to the duration of the second stage and compared in terms of mode of delivery, maternal and neonatal morbidity. RESULTS: group 1 (85 %) had a second stage of labor inferior to 3 hours and group 2 (15 %) ? 3 hours. The cesarean deliveries for non-engagement of the fetus were significantly higher in group 2. No significant difference was observed in terms of maternal morbidity. The median Apgar score at 5 minutes was higher in group 1. The proportion of babies transferred to neonatal intensive care and to the neonatology department was higher in group 2. CONCLUSION: we mainly noted an increase in neonatal morbidity when the second stage exceeded 3 hours, which is consistent with literature where an increase in maternal morbidity is also described. Prolonging the second stage therefore seems inappropriate to us in the current state of knowledge.

OBJECTIFS: la gestion du second stade de travail et sa durée optimale sont controversées, particulièrement pour les patientes nullipares. Notre objectif est d'étudier l'impact d'un second stade prolongé sur la morbidité périnatale dans notre institution. Matériel et méthodes : il s'agit d'une étude rétrospective menée au CHU de Liège de janvier à juillet 2019. Les 160 patientes incluses ont été réparties en deux groupes en fonction de la durée du second stade et comparées en termes de mode d'accouchement, morbidité maternelle et néonatale. Résultats : le groupe 1 (85 %) présentait un second stade inf�rieur a 3 heures et le groupe 2 (15 %) ? 3 heures. Les césariennes pour non-engagement étaient significativement plus élevées dans le groupe 2. Aucune différence significative n'a été observée en termes de morbidité maternelle. Le score d'Apgar médian à 5 minutes était plus élevé dans le groupe 1. La proportion de bébés transférés au NIC («Neonatal Intensive Care¼) et en néonatologie était plus élevée dans le groupe 2. CONCLUSION: nous avons principalement noté une majoration de la morbidité néonatale lorsque le second stade dépassait 3 heures, ce qui rejoint la littérature où l'on décrit, également, une majoration de la morbidité maternelle. Prolonger le second stade nous semble, dès lors, inapproprié dans l'état actuel des connaissances.

Monteggia fractures: analysis of patient-reported outcome measurements in correlation with ulnar fracture localization.

BACKGROUND: Monteggia fractures and Monteggia-like lesions result after severe trauma and have high complication rates. Preliminary biomechanical studies suggested a correlation between ulnar fracture localization and clinical result. OBJECTIVES: Key objective was to evaluate whether the site of the ulnar fracture can be correlated to clinical outcome after open reduction and internal stabilization. METHODS: In a retrospective, monocentric study 35 patients who underwent surgical treatment after suffering a Monteggia injury or Monteggia-like lesion were included. Fractures were classified according to Bado and Jupiter, the site of the fracture location at the proximal ulna and regarding the potential accompanying ligamentary injury. In a follow-up examination validated patient-reported outcome measures and functional parameters were evaluated. Furthermore, treatment strategy and complications were analysed. RESULTS: Mean patient age was 51.9 years (± 18.0). 69% were females (n = 24). Follow-up took place after 50.5 months (± 22.1). Fractures were classified according to Bado (I:2, II:27, III:4, IV:2). Bado II-fractures were further classified according to Jupiter (A:7, B:16, C:3, D:1). Cases were divided into subgroups depending upon the distance of the ulnar fracture site in respect to its distal endpoint (A: < 7 cm and B: > 7 cm). Average overall MEPS was 84.1 (± 19.0). Oxford elbow score and DASH were 37.2 (± 10.5) and 20.4 (± 20.5). Average extension capability reached - 7° (± 7.5). Mean flexion was 134.8° (± 19.7). Average pain according to visual analogue scale was 1.6 (± 1.9). We found no differences between the subgroups regarding the PROMs. Subgroup A displayed a worse extension capability (p = 0.027) and patients were significantly older (p < 0.01). Comparing patients with and without fracture of the radial head, we observed no differences. Patients with an accompanying injury of the coronoid process displayed higher pain levels (p = 0.011), a worse functionality (p = 0.027) and overall lower scoring in PROM. CONCLUSION: The presented results suggest that in Monteggia fractures and Monteggia-like lesions, the localization of the ulna fracture can give a hint for its postoperative outcome. However, we could not confirm the hypothesis of an increasing instability in ulnar fractures located further distally (high severity of the potential ligamentous injury). Intraarticular fractures or injuries with a close relation to the joint have a worse prognosis, especially if the coronoid process is injured. Trial registration Registration was done with ClinicalTrials.gov under NCT05325268.

[Clinical impact of small bowell capsule endoscopy in obscure gastrointestinal bleeding : retrospective single-center study]. / Impact clinique de la vidéocapsule endoscopique du grêle dans les saignements digestifs inexpliqués. Etude rétrospective monocentrique.

INTRODUCTION: The small-bowel capsule endoscopy (VCE) has been validated in the investigation of obscure gastrointestinal bleeding (OGIB). The aim of this study was to evaluate the clinical impact of VCE for OGIB in routine practice, in terms of subsequent management and the risk of rebleeding. METHODS: Our retrospective study analyzed the VCE at the CHU of Liège from March 2016 to December 2019 (cohort of 110 patients with OGIB). RESULTS: We found a diagnostic yield of 58 %, a change in therapeutic attitude in 39 % of patients and a recurrence rate of 22.5 % (out of 102 patients followed at 2 years). The rate of rebleeding was particularly low in patients with normal VCE and in those for whom a therapeutic modification was made. Finally, about 45 % of patients did not have any change in therapeutic attitude nor recurrence. CONCLUSION: VCE leads to a therapeutic modification in about 40 % of patients with a low risk of relapse. However, VCE could be avoided in some patients as evidenced by a subgroup representing 45 % of patients for whom there was no therapeutic modification nor recurrence.

introduction et but : La vidéocapsule endoscopique grêle (VCE) est validée dans l'exploration des saignements digestifs inexpliqués (OGIB). Le but de notre travail a été d'évaluer l'impact clinique de la réalisation d'une VCE pour OGIB en pratique courante, en termes de prise en charge ultérieure et de risque de récidive du saignement. Méthodes : Notre étude rétrospective a analysé les VCE réalisées au CHU de Liège de mars 2016 à décembre 2019. Résultats : Les VCE de 110 patients ont été rétrospectivement analysées. Nous avons observé un pouvoir diagnostique de 58 % et une modification d'attitude thérapeutique chez 39 % des patients. Le taux de récidive (pour les 102 patients dont le suivi était disponible à maximum 2 ans) était de 22,5 %. Le taux de récidive de saignement était particulièrement faible chez les patients avec VCE normale et chez ceux pour lesquels une modification thérapeutique a été faite. Enfin, environ 45 % des patients n'ont pas eu de modification de l'attitude thérapeutique ni de récidive. Conclusions : La VCE débouche sur une modification thérapeutique chez environ 40 % des patients avec, dans la foulée, un faible risque de récidive. Par contre, la VCE pourrait être évitée chez certains patients comme en témoigne un sous-groupe représentant 45 % des patients pour lesquels il n'y a eu ni modification thérapeutique ni rechute.

The impact of an ultra-trail on the dynamic of cardiac, inflammatory, renal and oxidative stress biological markers correlated with electrocardiogram and echocardiogram.

The aim of this study was to describe the effects of a 64.2 km ultra-trail on the biomarkers of muscle damage, inflammation and oxidative stress, and compare the results observed with an ECG and an echocardiogram, both performed before and after the race.Thirty-three ultra-trail volunteers (45.8 ± 8.7 years old) were enrolled in our study. Three blood tests were drawn from each runner, one just before (TPRE), one just after (TPOST) and the last 3 h after the end of the race (TPOST3h).All the markers increased. The maximum concentrations observed were at TPOST3h and were significant (p < 0.001) for creatine kinase, creatine kinase isoform MB, high-sensitivity C-reactive protein, uric acid and for the ratio of reduced glutathione to oxidised glutathione. However, in the case of myoglobin, high-sensitive troponin T, N-terminal pro-brain natriuretic peptide, oxidised glutathione, myeloperoxidase, cystatin C and creatinine, the most significant increases were at TPOST (p < 0.001). Modifications were observed in the medical imaging using echocardiography such as reduction of left ventricule end-sytolic and diastolic volumes and left ventricular global longitudinal strain. ECG showed electrical criteria for left ventricular hypertrophy and incomplete right bundle branch block after the race.Endurance races cause significant physiological stress to the body that can be measured by the increase of different biomarkers. From a laboratory perspective, it is important to take into account the possible exercise performed previous to the testing to avoid a misinterpretation of the results. From a training perspective, due to these increases in biomarkers, it is recommended that runners wait at least 72 h after an ultra-trail before subsequent training. In addition a transient impairment of ventricular function due to dehydration were observed.

Ustekinumab in bio-naïve and bio-failure Crohn's disease patients: Results from a « real-life ¼ monocentric cohort.

BACKGROUND: The pivotal clinical trials have largely demonstrated the efficacy and safety of ustekinumab in Crohn's disease. Real-life cohorts published so far only include very few bio-naïve patients. This study assesses effectiveness and safety of ustekinumab in bio-naïve and bio-failure patients treated with ustekinumab in routine practice and look for predictors of response. METHODS: We performed a retrospective monocentric study. Initial response was assessed by maintenance therapy beyond week 16. Sustained response was assessed by the continuation or cessation of therapy over time for another reason than stopping in sustained remission. Treatment persistence was assessed by Kaplan Meier curves and predictors of treatment persistence were studied by univariate and multivariate Cox model. RESULTS: Out of 156 recorded patients, three patients were still in their induction phase at time of analysis and 5 patients were lost to follow-up, leaving 148 patients for clinical effectiveness analyses, including 35 bio-naïve when starting ustekinumab. A maintenance therapy was initiated in 79.7%. At one year, the probability to be still treated with ustekinumab was 73.8%. Treatment cessation increased with smoking in multivariate analysis. Previous biologic failure (as a whole), CRP and fecal calprotectin baseline levels did not influence initial response and treatment persistence. CONCLUSION: A large proportion of CD patients initially respond to ustekinumab and continue this treatment beyond one year. Treatment persistence is as high in bio-failure as in bio-naïve patients.

[Elective induction of labor in nulliparous women : should we stop ?] / L'induction élective du travail chez la patiente nullipare : stop ou encore ?

In Wallonia, almost one fourth of cesarean sections are performed on nulliparous women with vertex nonanomalous singleton gestations who underwent induction of labor. The purpose of this study is to compare maternal and neonatal outcomes with elective induction of labor versus spontaneous onset of labor. Data for all deliveries at CHU de Liège over a two-year period were obtained. Women with vertex nonanomalous singleton gestations who delivered from 3900 to 40+6 weeks were selected. We tested the association of elective induction and operative vaginal delivery, cesarean section, post-partum hemorrhage, episiotomy and perineal lacerations, length of labor, length of stay, 1-min and 5-min APGAR inferior to 7 and admission to neonatal intensive care unit. Length of stay was significantly longer in all induced women. In nulliparous women, there was a 45 % probability of operative vaginal delivery or cesarean section delivery in those who underwent elective induction of labor. In light of these results, it seems that our policy of elective induction of labor in nulliparous women is causing unnecessary and potentially avoidable interventions.

En Wallonie, l'induction du travail chez les patientes nullipares avec grossesse singleton en présentation céphalique recrute près d'un quart de l'ensemble des césariennes réalisées. L'objectif de cette étude est de comparer le travail spontané et l'induction élective du travail en termes d'issues obstétricales et de morbidités maternelles et néonatales. Entre janvier 2015 et décembre 2016, les femmes ayant accouché entre 390 et 40+6 semaines d'aménorrhée (SA) au CHU de Liège et ayant présenté une grossesse singleton avec présentation céphalique, sans pathologie maternelle, gravidique ou fœtale ont été sélectionnées. Les variables suivantes ont été retenues : taux d'extraction instrumentale, taux de césarienne, type d'hémorragie du post-partum, état du périnée, durée du travail, durée d'hospitalisation, APGAR (1-5 min) défavorable (inf�rieur a 7) et passage en néonatologie. La durée d'hospitalisation est augmentée chez toutes les femmes induites. Chez les patientes nullipares, l'induction élective se solde, dans 45 % des cas, par une extraction instrumentale ou une césarienne en cours de travail. Nos pratiques d'induction élective chez les patientes nullipares pourraient être responsables d'un certain nombre d'interventions non nécessaires et évitables.

Use of methotrexate in the treatment of ectopic pregnancies: a retrospective single center study.

INTRODUCTION: The aim of this study was to evaluate the efficacy of methotrexate (MTX) in the treatment of ectopic pregnancies. We identified predictive factors of success or failure and compared our results with previous studies to make recommendations for its use. MATERIAL AND METHODS: A cohort of 61 patients from a single center was retrospectively analyzed. Inclusion criteria were a diagnosis of ectopic pregnancy and treatment with a single-dose injection of MTX. The need to perform surgery despite MTX was defined as treatment failure while needing a second MTX injection was not. RESULTS: In our cohort, MTX demonstrated a success rate of 80%. This rate rose to 84% when patients with human Chorionic Gonadotropin (hCG ) > 5,000 IU/L were excluded. Twenty percent underwent surgery for pain, increased mass size and/or suboptimal hCG kinetics. Low hCG levels on days 0, 4 and 7 as well as the absence of pain, metrorrhagia and hemoperitoneum were predictive of success. MTX was also efficient in the treatment of persisting pregnancies of unknown location (PUL). CONCLUSION: Our results are consistent with previous studies and emphasize the fact that MTX is less effective above a certain level of hCG. We obtained a cut-off value of 2439 IU/L with a sensitivity of 66.7% and a specificity of 93.9%. MTX should not be used when hCG is higher than 5,000 IU/L and laparoscopic surgery should be performed. Our results bring additional data about the efficacy of MTX in the management of persisting pregnancies of unknown location.

Predictors of a good response to inhaled corticosteroids in obesity-associated asthma.

INTRODUCTION: Asthma in obese subjects is poorly understood. According to GINA guidelines, pulmonologists increase ICS in case of poor asthma control but lung volume restriction may also worsen respiratory symptoms in obese asthmatics leading to overtreatment in this subpopulation. METHODS: We conducted a retrospective study on 1217 asthmatics recruited from University Hospital of Liege. 92 patients with a BMI ≥30 came at least two times at the asthma clinic (mean interval: 335 days). In this obese population, we identified predictors of good (decrease in ACQ ≥0.5) versus poor response (rise in ACQ ≥0.5) to ICS step-up therapy. RESULTS: Obese asthmatics had a poorer asthma control and quality of life as compared to non-obese and exhibited reduced FVC, higher levels of blood leucocytes and markers of systemic inflammation. The proportion of asthma inflammatory phenotypes was similar to that observed in a general population of asthmatics. Among uncontrolled obese asthmatics receiving ICS step-up therapy, 53% improved their asthma control while 31% had a worsening of their asthma. Uncontrolled obese asthmatics showing a good response to increase in ICS had higher ACQ, lower CRP levels, higher sputum eosinophil counts and higher FeNO levels at visit 1. Uncontrolled obese asthmatics that worsened after increasing the dose of ICS had lower FVC, lower sputum eosinophil counts and higher sputum neutrophil counts. CONCLUSION: We observed poorer asthma control in obese asthmatics despite similar bronchial inflammation. Managing obese asthmatics according to ACQ alone seems to underestimate asthma control and the contribution of restriction to dyspnea. Increasing the dose of ICS in the absence of sputum eosinophilic inflammation or in the presence of restriction or bronchial neutrophilia led to poorer asthma control. In those patients, management of obesity should be the first choice.

Variation of the maximum velocity along the umbilical vein supports the Reynolds pulsometer model.

OBJECTIVE: To challenge, with a modern sonographic approach and a numerical model, the Reynolds's concept which suggests that the vascular structure of the umbilical cord could act as a pulsometer facilitating the venous return to the foetus. METHOD: Forty-five patients between 20 and 28 weeks of gestation were included in the study. The blood maximum velocity in the umbilical vein, measured at both foetal and placental ends, was assessed. Several sonographic parameters of the cord, including the diameter of the umbilical vein at both extremities, cord cross-sectional area and Wharton's jelly section surface were measured. We compare our data with those of a numerical model. RESULTS: A difference in maximum velocity between the two extremities of the umbilical vein (ΔUVVmax) was noted. The maximum velocity was significantly higher at the foetal umbilical end (14.12 +/-3.18 cm/s) than at the placental end (11.93 +/-2.55 cm/s; p < 0.0001). The mean difference is 2.2 +/- 2.3 cm/s. No difference in the umbilical vein diameter was measured at both cord ends (umbilical 4.85 +/-0.9 mm, placental 4.86 +/-0.87 mm, p < 0.0001). There is no significant relationship between ΔUVVmax and the cord cross-sectional area or Wharton's jelly index. CONCLUSION: Modifications of the spatial velocity profile together with the pulsometer model could explain the maximum velocity changes that is measured in the umbilical vein along the cord. This numerical model consolidates the sonographic observations.

A single center experience in resectable pancreatic ductal adenocarcinoma : the limitations of the surgery-first approach. Critical review of the literature and proposals for practice update.

BACKGROUND AND STUDY AIMS: The current standard of care for resectable pancreatic ductal adenocarcinoma (PDAC) is surgery-first followed by adjuvant chemotherapy. We review our single center experience in a PDAC cohort managed by the surgery-first strategy. We then compare our data to those of Belgian and international literature. PATIENTS METHODS: We reviewed a series of 83 consecutive resectable patients with PDAC, treated by the surgery-first approach in a Belgian Academic Hospital between 2007 and 2013. The outcomes were assessed with univariate and multivariate Cox regression analysis. Kaplan-Meier curves were drawn according to patient groups. RESULTS: For the entire population, the median survival (MS) was 18.4 months; the 1-year relapse-free survival was 56%, and the 5-year overall survival (OS) was 13%. The size of the primary tumor larger than 3 cm (OS, HR = 1.76, p = 0.033) and vascular resection (DFS, HR = 2.1, p = 0.024) were the single independent prognostic factors in the multivariate analysis of this cohort. Only 69% of the patients received adjuvant chemotherapy, and more than 75% of them demonstrated no chance of survival beyond 3 years because they harbored poor prognostic factors, recognized only postoperatively. CONCLUSIONS: Our results and those published in the literature brought to light the limited perspectives of the surgery-first strategy in a population of apparently resectable pancreatic cancers. In comparison, data from reported neo-adjuvant series deserve our interest to bring this strategy upfront in selected patients in the context of close observational monitoring and randomized trials. The actual standard of care for resectable PDAC is surgery-first followed by adjuvant chemotherapy. The performance of this strategy relies on the dedicated imaging that does not accurately recognize the limits of the tumor and the high prevalence of adverse prognostic factors. Moreover, pancreatectomy remains associated with high postoperative complication rates and the poor completion of adjuvant therapy. This translates into poor long-term survival figures. In our series the MS was 18.4 months and 5-year OS was 13%. The disease-free survival (DFS) was 15.6 months, 1 and 3-year DFS were 56 and 26%, respectively. The variables that significantly correlated with OS in univariate analysis are tumor size and lymph node involvement. Regarding DFS, vascular resection was the only significant factor. In the multivariate analysis, the only significant factor related to OS remained the tumor size >3 cm in greatest diameter. Vascular resection remained significant for DFS. 31% of the patients did not receive any chemotherapy at all before the 6-month period following resection. The rates of complete resections compared favorably with those of a surgery-first strategy with no excess of operative mortality, complications and early relapse rates. The advantages of a chemotherapy-first approach, eventually combined with chemo-radiotherapy, are to offer higher combined therapy completion rates and improve the level of free resection margins, lymph node involvement and patient selection. The advent of safe, more potent chemotherapy combinations has the potential to further improve survival when administered upfront.

Persisting signs of disease activity at Magnetic Resonance Enterocolonography predict clinical relapse and disease progression in quiescent Crohn's disease.

INTRODUCTION: Deep remission including clinical remission and tissue healing has been advocated as the therapeutic target in Crohn's disease. Yet, the definition of deep remission remains unclear. The aim of this study was to assess the persisting lesions at magnetic resonance enterocolonography (MREC) in clinically quiescent Crohn's disease as well as their relapse predictive value. METHODS: we performed a prospective monocentre cohort study. We included patients with clinical remission. At baseline, these patients had blood tests, the measurement of fecal calprotectin and underwent a MREC. They were then followed up clinically for a minimum of 1 year. A relapse was defined by a HBI > 4 with an increase of at least 3 points. Correlations between clinical, demographic, biological parameters and MREC signs were assessed as well as the time-to-relapse predictive value of the studied variables. RESULTS: Twenty seven patients were recruited. Fourteen out of 27 had persisting disease activity at MREC. MREC signs only partly correlated with biomarkers. Ten out of 27 patients relapsed over a median follow up of 25 months. In univariate analysis, relative contrast enhancement of the most affected segment (HR: 2.56; P = 0.046), ulcers (HR: 12.5; P = 0.039), fistulas (HR: 14.1; P = 0.009) and target sign (HR: 3.63; P = 0.049) were associated with relapse. In multivariate analysis, fistula was the only one. CONCLUSIONS: Half of the patients with clinically quiescent Crohn's disease had persisting signs of disease activity at MREC. These signs predicted time-to-relapse.

Oncological and surgical outcome after oncoplastic breast surgery.

BACKGROUND: Oncoplastic surgery combines breast-conserving treatment and plastic surgery techniques. The aim of the study was to identify breast and tumor-related characteristics that contribute to the rate of complications and recurrence. METHODS: This retrospective study included 72 patients with a median follow-up of 32 months. For each patient, a comprehensive set of data was collected, including epidemiology, tumor characteristics, preoperative information, detailed pathology reports, radiotherapy treatment and type of surgical technique. The rate of complications, recurrence and survival were studied. RESULTS: Complete tumor removal was performed with clear margins in all patients but in 25 of them margins were less than 2 mm. One patient had local recurrence and another developed distant metastases. The study showed that the size of the margin was not predictive of recurrence as long as not positive; the greater the resection volume, the larger the excision margin. The resection size was the only factor influencing complications and no specific tumor-related factor significantly increased the complication rate. Surgical complications did not delay the initiation of chemotherapy and radiotherapy. CONCLUSIONS: This is the first oncoplastic study where both tumor and breast characteristics were analyzed using the most recent criteria of the literature. Oncoplastic surgery can be considered as oncologically safe. The resection size was the sole significant risk factor for postoperative complications. Complications after oncoplastic breast surgery did not differ neoadjuvant therapy. Long-term event-free survival was excellent (96% at 7 years).

Satellite lesions accompanying herpes zoster: a new prognostic sign for high-risk zoster.

BACKGROUND: The incidence, clinical relevance and pathogenesis of single, isolated, varicella-like skin lesions occurring far beyond the primary herpes zoster (HZ)-affected dermatome remain unclear. OBJECTIVES: To search prospectively for these satellite lesions in 120 patients with HZ and to correlate their presence with a series of clinical, histological and virological data. METHODS: Relevant clinical data were recorded from 109 patients with proven HZ using immunohistochemistry on Tzanck smears. Furthermore, skin biopsies and blood samples were obtained from a subgroup of patients presenting with primary HZ with and without satellite lesions for histology, immunohistology, serology and real-time polymerase chain reaction. RESULTS: This study identified satellite lesions in 21·1% of the patients with HZ. Their presence conveyed a statistically significant relative risk (RR) for severe (RR 3·27, P < 0·001), multidermatomal (RR 10·6, P < 0·001) and multistage HZ (RR 3·30, P < 0·001); systemic signs (RR 2·08, P = 0·0031); immunosuppression (RR 2·38, P = 0·0014) and hospitalization (RR 2·94, P < 0·001). Varicella zoster virus (VZV) viraemia was higher (mean 4075 copies mL(-1) ) in patients with HZ with satellite lesions than in those without (mean 1466 copies mL(-1) ). In contrast to HZ lesions, satellite lesions often presented positive VZV immunostaining in endothelial cells, suggesting a similar pathogenesis to varicella. A limitation of this study is the centre-linked overrepresentation of immunocompromised patients. CONCLUSIONS: Total-body examination searching for satellite lesions is a rapid, simple and reliable tool for identifying patients with high-risk HZ.

Depth of remission in Crohn's disease patients seen in a referral centre : associated factors and impact on disease outcome.

INTRODUCTION: Our goals were to assess the prevalence of biological and tissue remission in routine practice in Crohn's disease, and to evaluate the correlation between biological or tissue remission and clinical or demographic characteristics as well as their impact on disease outcome. METHODS: We performed a retrospective monocenter study. Biological remission was defined by a CRP < 5 mg/I. Tissue remission was defined by the absence of ulcer at endoscopy and/or absence of signs of acute inflammation at MRI. Association with demographic, clinical and laboratory markers was studied by logistic regression models and rates of relapses, hospitalizations and surgeries were compared using the logrank test. RESULTS: Among the 263 patients included, 147 were in clinical remission; 102/147 (69%) were in biological remission. Fifty-six patients also had morphological evaluation: 37 (66%) were in tissue remission. Biological remission was associated with older age, higher hemoglobin and lower BMI. Tissue remission was associated with older age, lower platelets count, absence of previous surgery, and the use of immunosuppressant. Time-to-relapse was significantly longer in patients with biological remission and in patients with tissue remission as compared to patients without biological or tissue remission. CONCLUSIONS: Among the patients in clinical remission seen as outpatients, two thirds were either in biological and/or tissue remission. Biological and/or tissue remission was associated with a better outcome than clinical remission alone.

Onset of quantum chaos in molecular systems and the zeros of the Husimi function.

The distribution of zeros of the Husimi function has proven a useful tool in the characterization of regular and chaotic quantum states of dynamical systems. In a previous paper [Phys. Rev. E 82, 026201 (2010)], we showed how the quantum transition from order to chaos in three different molecular systems (LiCN, HCN, and HO(2)) can be understood by means of the correlation diagram of eigenenergies versus the Planck's constant. An order-chaos frontier of scars (eigenstates localized over unstable and stable complementary, in the sense of the Poincaré-Birkhoff theorem, periodic orbits) was observed. In this paper, we show how the distribution of zeros of the Husimi function can be related to the onset of chaos in these molecular systems, showing a very interesting feature at the frontier of scars; namely, some zeros of the Husimi function localize over the stable and unstable fixed points corresponding to the two complementary periodic orbits, this representing the quantum equivalent to the Poincaré-Birkhoff theorem.
