Radiomics analysis of 18F-Choline PET/CT in the prediction of disease outcome in high-risk prostate cancer: an explorative study on machine learning …

2021

Objective: The aim of this study was (1) to investigate the application of texture analysis of choline PET/CT images in prostate cancer (PCa) patients and (2) to propose a machine-learning radiomics model able to select PET features predictive of disease progression in PCa patients with a same high-risk class at restaging. Material and methods: Ninety-four high-risk PCa patients who underwent restaging Cho-PET/CT were analyzed. Follow-up data were recorded for a minimum of 13 months after the PET/CT scan. PET images were imported in LIFEx toolbox to extract 51 features from each lesion. A statistical system based on correlation matrix and point-biserial-correlation coefficient has been impl…

Coeliac disease: Oral ulcer prevalence, assessment of risk and association with gluten-free diet in children.

2008

Aims. Oral mucosal lesions may be markers of chronic gastrointestinal disorders, such as those causing malabsorption. Our objectives were to assess the prevalence of recurrent oral aphthous-like ulcers in coeliac disease patients living in the Mediterranean area, and to evaluate the impact of a gluten-free diet. Methods. A test group of 269 patients (age range 3-17 years) with coeliac disease confirmed both serologically and histologically was compared with a control group of 575 otherwise clinically healthy subjects for the presence, or a positive history of aphthous-like ulcers. Coeliac disease patients with aphthous-like ulcers were re-evaluated 1-year after starting a gluten-free diet. …

Mycotic Aneurysm of Both Internal Iliac Arteries due to Candida albicans.

2013

International audience; : We report the case of a 21-year-old man, with a Candida-related endocarditis causing multiple emboli and bilateral false aneurysms of the internal iliac arteries. As the distal runoff vasculatures of both internal iliac arteries were occluded, these arteries required ligation. Although there were few consequences with the procedure, multiple emboli and recurrence of endocarditis after cardiac surgery led to the patient's death.

Peak Exercise Oxygen Uptake Predicts Recurrent Admissions in Heart Failure With Preserved Ejection Fraction

2018

Introduction and objectives: Heart failure with preserved ejection fraction (HFpEF) is a highly prevalent syndrome with an elevated risk of morbidity and mortality. To date, there is scarce evidence on the role of peak exercise oxygen uptake (peak VO2) for predicting the morbidity burden in HFpEF. We sought to evaluate the association between peak VO2 and the risk of recurrent hospitalizations in patients with HFpEF. Methods: A total of 74 stable symptomatic patients with HFpEF underwent a cardiopulmonary exercise test between June 2012 and May 2016. A negative binomial regression method was used to determine the association between the percentage of predicted peak VO2 (pp-peak V02) and rec…

Patterns of recurrence of obstructing colon cancers after surgery for cure: a population-based study.

2013

Aim Little is known about patterns of recurrence in obstructing colon cancer (OCC) at a population level. The aim of this study was to determine the risk of recurrence following potentially curative surgery in OCC compared with that in uncomplicated colon cancer (CC). Method Data were obtained from the population-based digestive cancer registry of Burgundy (France). Local and distant failure rates were calculated using actuarial methods. A multivariate analysis was performed using a Cox model. Results Obstructing colon cancer represented 8.5% of all colon cancers resected with curative intent (n = 3375). The 5-year cumulative local recurrence rate was 14.2% for OCC and 7.6% for nonobstructi…

Rectal cancer threatening or affecting the prostatic plane: is partial prostatectomy oncologically adequate? Results of a multicentre retrospective s…

2015

Aim The management of rectal cancer threatening or affecting the prostatic plane is still under debate. The role of preoperative chemo radiotherapy and the extent of prostatectomy seem to be key points in the treatment of these tumours. The aim of the present study was to evaluate the pathological circumferential margin status and the local recurrence rate following different therapeutic options. Method A multicentre, retrospective study was conducted of patients with rectal cancer threatening or affecting the prostatic plane, but not the bladder, judged by magnetic resonance imaging (MRI). The use of preoperative chemoradiotherapy and the type of urologic resection were correlated with the…

Long-term clinical outcomes after drug-eluting stent implantation in unprotected left main coronary artery disease.

2009

Objective: To investigate long-term outcomes of unprotected left main coronary artery (ULMCA) disease treatment using drug-eluting stents (DES). Background: In several studies, DES implantation in ULMCA appeared safe and effective at mid-term; however, to date, there is limited long-term data. Methods: All consecutive patients undergoing sirolimus- or paclitaxel-eluting stent implantation in ULMCA disease at a single institution were evaluated. The primary endpoint was long-term major adverse cardiac events (MACE) defined as cardiac death, nonfatal myocardial infarction, or target lesion revascularization (TLR). Stent thrombosis (ST), according to Academic Research Consortium definitions, w…

Recurrence of Acute Gallstone Pancreatitis and Relationship with Cholecystectomy or Endoscopic Sphincterotomy

2004

To determine the prevalence of recurrence of gallstone pancreatitis, its clinical features, and the presence of prognostic factors of recurrence.From January 1, 2000 to August 31, 2003, 233 patients admitted with acute gallstone pancreatitis (AGP) were prospectively studied. Patients were divided into two groups: recurrent and nonrecurrent group. Clinical, analytical, radiological, prognostic parameters, and severity (Atlanta criteria) were assessed, along with the performance of cholecystectomy or endoscopic sphincterotomy (ES). Clinical features of recurrence were analyzed. Univariate (chi(2), Student's t-test) and multivariate tests were performed. Statistical significance was assumed if…

How to treat tumefactive demyelinating disease?

2013

Glioma-like inflammatory demyelinating lesions can be found in patients with pre-diagnosed multiple sclerosis, but they have also been described as an isolated disease entity. The initial diagnostic work-up usually includes a biopsy for histopathological analysis. However, even after unambiguous histopathologic classification, tumefactive lesions pose a therapeutic challenge. Until now, there have been no guidelines on how to treat patients with these rare and extreme lesion phenotypes. Here we report a patient with a relapsing unifocal tumefactive demyelinating lesion. The patient initially showed a good response to steroid treatment, with full clinical recovery. However, after relapse of…

Urokinase-plasminogen-activator receptor expression in disseminated tumour cells in the bone marrow and peripheral blood of patients with clinically …

2009

OBJECTIVE To evaluate the expression of urokinase-plasminogen-activator receptor (uPA-R) in disseminated tumour cells (DTC) in bone marrow (BM) and peripheral blood (PB) of patients with clinically localized prostate cancer before radical prostatectomy (RP), and to assess the associations with pathological variables and prognosis. PATIENTS AND METHODS In all, 52 patients (47 with clinically localized cancer and five with benign prostatic hyperplasia, BPH, as controls) were prospectively enrolled. BM and PB samples were drawn before surgery. DTC were enriched using a commercial system, cytokeratin (CK) 8/18 was used to detect DTC, and uPA-R expression was detected by dual-immunostaining of t…
