Prospective Comparison of Loop Excision under Colposcopic Guidance versus Vitom Guidance.

2012

Background: Aim of the study was to compare the quality of loop excision using a colposcope with results using the VITOM system. Results compared included cervical volume removed, intra- and postoperative complications, and positive resection margins. Methods: A total of 200 patients with histologically confirmed high-grade cervical premalignant lesions, persistent atypical cytological results and/or suspicious colposcopic findings, and cytological and histological discrepancies were included in the study. In transformation zone type 1 (T1) only a superficial cone biopsy was done, in zones type 2 and 3 (T2 and T3) a superficial outside cone biopsy or a deeper inside cone biopsy were done re…

Approximated overlap error for the evaluation of feature descriptors on 3D scenes

2013

This paper presents a new framework to evaluate feature descriptors on 3D datasets. The proposed method employs the approximated overlap error in order to conform with the reference planar evaluation case of the Oxford dataset based on the overlap error. The method takes into account not only the keypoint centre but also the feature shape and it does not require complex data setups, depth maps or an accurate camera calibration. Only a ground-truth fundamental matrix should be computed, so that the dataset can be freely extended by adding further images. The proposed approach is robust to false positives occurring in the evaluation process, which do not introduce any relevant changes in the …

Design and calibration of an omni-RGB+D camera

2016

International audience; In this paper, we present the design of a new camera combining both predator-like and prey-like vision features. This setup provides both a spherical RGB-view and a directional depth-view of the environment. The model and calibration of the full setup are described. A few examples will be given to demonstrate the interest and the versatility of such camera for robotics and video surveillance at the oral presentation.

The diagnosis and management of gastric cancer: Expert discussion and recommendations from the 12th ESMO/World Congress on Gastrointestinal Cancer, B…

2011

Well-recognized experts in the field of gastric cancer discussed during the 12th European Society Medical Oncology (ESMO)/World Congress Gastrointestinal Cancer (WCGIC) in Barcelona many important and controversial topics on the diagnosis and management of patients with gastric cancer. This article summarizes the recommendations and expert opinion on gastric cancer. It discusses and reflects on the regional differences in the incidence and care of gastric cancer, the definition of gastro-esophageal junction and its implication for treatment strategies and presents the latest recommendations in the staging and treatment of primary and metastatic gastric cancer. Recognition is given to the ne…

Counseling Patients with a Glioblastoma Amenable Only for Subtotal Resection: Results of a Multicenter Retrospective Assessment of Survival and Neuro…

2017

Background Patients with a glioblastoma (GB) amenable only for subtotal resection (STR) represent a challenge in patient counseling. Our objective was to assess impact of extent of resection (EoR) on survival and clinical outcome of these patients. Methods We performed a retrospective multicenter assessment. Patients receiving an intended STR in 3 centers with unilocular, primary, highly eloquent GB who received the same adjuvant treatment were included. We assessed EoR, neurologic outcome, and rate of complications. Progression-free survival (PFS) and overall survival (OS) were calculated with Kaplan–Meier estimations. We used 1% EoR and 1-cm3 steps to detect a threshold for a minimal EoR …

OP20 Risk and predictors of surgery in a newly diagnosed cohort of IBD patients in the biologic era: Results from the EpidemIBD study

2021

Abstract Background The management of inflammatory bowel disease (IBD) has substantially changed in the last decades, both in relation to medical and surgical treatments. Aims Principal: To know the rate of surgery in a newly diagnosed IBD cohort within the first year after diagnosis. Secondary: To describe the type of surgeries and indications in this cohort, and to identify predictive factors for surgery (focused on intestinal resection) in these patients. Methods Prospective, population-based nationwide registry. Adult patients diagnosed with IBD -Crohn’s disease (CD) and ulcerative colitis (UC)- during 2017 in Spain were included and were followed-up for 1 year. Kaplan-Meier curves were…

Vergleich der DNS-Analyse mit histomorphologischen parametern beim Magenkarzinom

1992

After curative resection of stomach carcinomas (adenocarcinomas: n=58, signet ring cell carcinomas: n = 24, undifferentiated carcinomas: n = 21) the DNA content of the tumor cells was compared with the histomorphological parameters. There was a correlation between the DNA content and the histomorphological parameters. The DNA analysis had no additionally prognostic influence. In the multivariate regression analysis the prognosis depended on lymph node status (p=0.0009), pT-stage (p = 0.02), tumor localization (p = 0.03) and the histological type (p=0.05). The prognosis was independent of the DNA content. Furthermore, neither did the degree of differentiation, the operative procedure, the sa…

Sonographische Verlaufskontrolle nach experimenteller Muskeldenervierung

2008

AIM: To describe sonographical results following acute, experimental muscle denervation. METHOD: Denervation of the supraspinatus and infraspinatus muscles was performed in 28 New Zealand white rabbits by segmental resection of the suprascapular nerve. The changes in the sonographic image of the muscles were follow up and documented at short intervals over 2 months. RESULTS: The sonographically detectable changes following denervation follow a definite pattern. In addition to the reduction in muscle diameter, sonographical signs of denervation include an increase of echodensity and an inhomogeneity of echotexture that appeared on day 14 after injury and became more prominent at larger inter…

Risk factors for residual disease at re-TUR in a large cohort of T1G3 patients

2021

Item does not contain fulltext Introduction and objectives: The goals of transurethral resection of a bladder tumor (TUR) are to completely resect the lesions and to make a correct diagnosis in order to adequately stage the patient. It is well known that the presence of detrusor muscle in the specimen is a prerequisite to minimize the risk of under staging. Persistent disease after resection of bladder tumors is not uncommon and is the reason why the European Guidelines recommended a re-TUR for all T1 tumors. It was recently published that when there is muscle in the specimen, re-TUR does not influence progression or cancer specific survival. We present here the patient and tumor factors th…
