Nonocclusion and Early Reopening of the Great Saphenous Vein After Endovenous Laser Treatment Is Fluence Dependent

2004

Background. Parameters influencing failure and recanalization rates of endovenous laser treatment (ELT) of the great saphenous vein (GSV) are still to be determined. Objective. To evaluate treatment-related parameters of ELT with respect to early failure of occlusion or recanalization of GSVs. Methods. A series of 77 consecutive patients received ELT of 106 GSVs with continuous pullback of the laser fiber. Duplex examination was performed at 1 day, 4 weeks, and 3 months after the procedure. Clinical patient and vessel characteristics as well as technical parameters of the ELT procedure were evaluated via multiple logistic regression analysis. Results. A median vein length of 60 cm (range of…

Peri-Tumoral Inflammatory Cell Infiltration in OSCC: A Reliable Marker of Local Recurrence and Prognosis? An Investigation Using Artificial Neural Ne…

2011

The presence of inflammatory reaction in peri-tumoural connective tissue is generally considered as a defense mechanism against cancer, but inflammation tissue in malignant transformation and early steps of oncogenesis has been recently proven to play a supporting and aggravating role in some carcinomas. Aims of this retrospective study were to evaluate in OSCCs the independent association of peri-tumoral inflammatory infiltrate (PTI) with local recurrence (LR) or survival outcome, and to verify whether PTI can be considered a marker of prognosis. Data from 211 cases of OSCC, only surgically treated between 1990 and 2000, were collected and retrospectively analyzed for PTI and the event LR…

Effect of obesity on disease-free and overall survival in node-positive breast cancer patients in a large French population: A pooled analysis of two…

2014

Abstract Background To examine the association between baseline body mass index (BMI), and disease-free survival (DFS) and overall survival (OS) in a large French early-stage breast cancer population included in the UNICANCER Programme d’Action Concerte Sein-01 (PACS01) and PACS04 phase III randomised trials. Methods After a median follow-up of 5.9 years, this report analyses 4996 patients with node-positive breast cancer, and randomly assigned to adjuvant anthracycline-based chemotherapy combined or not with taxanes. Univariate analyses were used to study the effects of well known prognostic factors and BMI on DFS and OS. BMI was obtained at baseline, before chemotherapy initiation, and ob…

Is extracapsular nodal extension in sentinel nodes a predictor for nonsentinel metastasis and is there an impact on survival parameters?-A retrospect…

2016

The Z0011 trial has fundamentally changed axillary management in breast cancer patients. However, some important questions remain, like the role of extracapsular nodal extension (ENE) in positive sentinel nodes and the need for further axillary treatment. In this retrospective cohort study, we reviewed and analyzed data from 342 clinically node negative (cN0) breast cancer patients with a positive sentinel node and subsequent axillary lymph node dissection (ALND) from the BRENDA data base. The 104 (30.4%) ENE positive patients had a significantly higher proportion of ≥3 positive axillary lymph nodes (65.0%) compared to ENE negative patients with a positive sentinel node (21.4%). Likewise, E…

Multivariate independent prognostic factors in endometrial carcinoma: A clinicopathologic study in 181 patients: 10 years experience at the Departmen…

2003

The aim of this study was to evaluate the biologic outcome of endometrial carcinomas as compared to clinical and pathologic parameters and to identify multivariate independent prognostic factors. Charts were abstracted from patients with endometrial carcinoma from 1985 to 1995. Data on clinicopathologic variables, adjuvant treatment, site of recurrence, and survival were collected. chi2 test was used to test association between variables. Kaplan-Maier method was used for survival analysis and Cox proportional hazards model for multiple regression analysis. Univariate analysis revealed that FIGO stage, tumor grade, depth of myometrial invasion, biochemical analysis of progesterone receptor s…

Systemic, environmental and lifestyle risk factors for dry eye disease in a mediterranean caucasian population

2022

Abstract Objectives To assess systemic, environmental and lifestyle risk factors for dry eye disease (DED) in a Mediterranean Caucasian population. Methods A cross-sectional study was performed on 120 Caucasian participants aged between 18 and 89 years (47.0 ± 22.8 years). Medical history, information regarding environmental conditions and lifestyle, Ocular Surface Disease Index, Dry Eye Questionnaire-5, non-Invasive (Oculus Keratograph 5 M) breakup time, tear film osmolarity and ocular surface staining parameters were assessed in a single clinical session to allow DED diagnosis based on the guidelines of the Tear Film and Ocular Surface Society Dry Eye Workshop II Diagnostic Methodology Re…

Simplified criteria for the diagnosis of autoimmune hepatitis

2008

Diagnosis of autoimmune hepatitis (AIH) may be challenging. However, early diagnosis is important because immunosuppression is life-saving. Diagnostic criteria of the International Autoimmune Hepatitis Group (IAIHG) were complex and purely meant for scientific purposes. This study of the IAIHG aims to define simplified diagnostic criteria for routine clinical practice. Candidate criteria included sex, age, autoantibodies, immunoglobulins, absence of viral hepatitis, and histology. The training set included 250 AIH patients and 193 controls from 11 centers worldwide. Scores were built from variables showing predictive ability in univariate analysis. Diagnostic value of each score was assesse…

Changes in Treatment of Very Elderly Patients Six Weeks after Discharge from Geriatrics Department

2020

We assessed the prescriptions of patients hospitalized in a geriatric unit and subsequently discharged. This prospective and observational study was conducted over a two-month period in the geriatrics department (acute and rehabilitation units) of a university hospital. Patients discharged from this department were included over a two-month period. Prescriptions were analyzed at admission and discharge from the geriatrics department (DGD), and six weeks after DGD. We included 209 patients, 63% female, aged 86.8 years. The mean number of medications prescribed was significantly higher at DGD than at admission (7.8 vs. 7.1, p = 0.003). During hospitalization, 1217 prescriptions were changed (…

Small, dense low-density lipoproteins (LDL) are predictors of cardio- and cerebro-vascular events in subjects with the metabolic syndrome

2009

Summary Objective  Small, dense low-density lipoproteins (LDL) are a feature of the metabolic syndrome (MS) but their predictive role still remains to be established. We performed a 2-year follow-up study in 124 subjects with MS (63 ± 6 years), as defined by the American Heart Association/National Heart, Lung and Blood Institute guidelines, to assess clinical and biochemical predictors of cerebro- and cardio-vascular events. Methods and results  Beyond traditional cardiovascular risk factors, we measured LDL size and subclasses by gradient gel electrophoresis. Clinical events were registered in the 25% of subjects. At univariate analysis subjects with events had increased prevalence of elev…
