Prognostic implications of circumferential location of distal rectal cancer
2010
Aim This study evaluated the prognostic importance of circumferential tumour position of mid and low rectal cancers. Method All uT2, uT3 and uT4 tumours of the middle and lower rectum that underwent total mesorectal excision (TME) with curative intent between 1996 and 2006 were included. The predominant circumferential tumour position (anterior, posterior or circumferential) was defined on preoperative endorectal ultrasound examination (ERUS). The relationships between tumour position and other characteristics and recurrence were explored. Results Two hundred and five patients with distal rectal cancer were operated on for a uT2-T4 tumour. Median follow up was 49 months. The location of …
A systematic review and meta-analysis comparing surgical and oncological outcomes of upper rectal, rectosigmoid and sigmoid tumours.
2021
Abstract Aim Management paradigms for tumours from the sigmoid colon to the lower rectum vary significantly. The upper rectum (UR) represents the transition point both anatomically and in treatment protocols. Above the UR is clearly defined and managed as colon cancer and below is managed as rectal cancer. This study compares outcomes between sigmoid, rectosigmoid and UR tumours to establish if differences exist in operative and oncological outcomes. Methods Electronic databases were searched for published studies with comparative data on peri-operative and oncological outcome for upper rectal and sigmoid/rectosigmoid (SRS) tumours treated without neoadjuvant radiation. The search adhered t…
Management of rectal cancer in France in a well-defined population.
2014
Objective The aim of this study was to draw a picture of diagnostic assessment and patterns of care for rectal cancer in France using population-based registries data. Methods The study included a random sample of 669 cases of rectal cancers diagnosed in 2005. Results Diagnostic assessment was performed by colonoscopy in 91.4% of the cases. An abdominal computed tomography was performed in 59.4% of the cases and chest computed tomography in 47.8%. An R0 resection was performed in 65.8% of cases and an R1/R2 resection in 16.1%. A rectal endosocography was performed in 40.4% and MRI in 10.4%. The sphincter was preserved in 73.6% of patients aged younger than 75 years of age and in 62.5% of th…
Multidetector Computed Tomography Angiography (MD-CTA) of Coronary Artery Bypass Grafts – Update 2017
2017
Coronary artery bypass grafting (CABG) is still an important therapeutic approach in the treatment especially of advanced coronary artery disease. In this study, we elucidate the current role of multidetector computed tomography angiography (MD-CTA) in imaging patients after CABG surgery.This study is based on recent reports in the literature (2007 - 2016) on imaging of CABG using 64-slice MD-CT scanners and beyond. We included 13 reports that compared ECG-gated MD-CTA with conventional invasive coronary angiography (ICA) as the reference standard for the assessment of graft patency and for the detection of 50 % stenoses. These studies had to provide absolute values for true-positive, true-…
General Adaption Framework
2005
Integration of heterogeneous applications and data sources into an interoperable system is one of the most relevant challenges for many knowledge-based corporations nowadays. Development of a global environment that would support knowledge transfer from human experts to automated Web services, which are able to learn, is a very profit-promising and challenging task. The domain of industrial maintenance is not an exception. This paper outlines in detail an approach for adaptation of heterogeneous Web resources into a unified environment as a first step toward interoperability of smart industrial resources, where distributed human experts and learning Web services are utilized by various devi…
Current state of dynamic surgery. A literature review.
2021
Background Recently, dental implant technology has been widely used for oral reconstruction. Dental implants are the treatment of choice for those patients with dental absences. An optimal implant placement is based on the prosthetic driven concept in order to achieve an aesthetic and functional restoration with a long-term prognosis. There are two types of guided implant surgery that are described in the literature: Static Guided Surgery (SGS) and Dynamic Guided Surgery (DGS). The aim of this study is to be aware of the current state of dynamic surgery and compare in the literature the discrepancies between planning and placement of dental implants. Material and Methods The study consists …
Comparison of the diagnostic efficacy of 2D radiography and cone beam computed tomography in persistent apical periodontal disease: A PRISMA-DTA syst…
2021
Objective The objective of this study was to answer the question: Do conventional radiographs (periapical/panoramic) afford better diagnostic outcomes than cone beam computed tomography (CBCT) as a complement for clinical diagnosis of apical lesions with persistent apical periodontitis or disease after root canal treatment? Study Design Five electronic databases were searched and provided information to enable construction of a table to determine primary diagnostic measures and secondary parameters. The evidence was appraised with the Quality Assessment of Diagnostic Accuracy Studies tool and GRADEpro software. Results Twenty-seven articles (9903 diagnostic images) were included. The pooled…
Technical and surgical aspects of the sphenopalatine ganglion (SPG) microstimulator insertion procedure
2015
Cluster headache (CH) is a debilitating, severe form of headache. A novel non-systemic therapy has been developed that produces therapeutic electrical stimulation to the sphenopalatine ganglion (SPG). A transoral surgical technique for inserting the Pulsante SPG Microstimulator into the pterygopalatine fossa (PPF) is presented herein. Technical aspects include detailed descriptions of the preoperative planning using computed tomography or cone beam computed tomography scans for presurgical digital microstimulator insertion into the patient specific anatomy and intraoperative verification of microstimulator placement. Surgical aspects include techniques to insert the microstimulator into the…
Protective Role of Conization Before Radical Hysterectomy in Early-Stage Cervical Cancer: A Propensity-Score Matching Study.
2021
Purpose: The purpose of this study was to assess the prognostic role and the perioperative outcomes of conization performed before radical hysterectomy in early-stage cervical carcinoma. Methods: This multicenter, retrospective observational cohort study included patients with FIGO 2009 stage IB1 cervical carcinoma treated with radical hysterectomy between June 2004 and June 2019. Patients were divided into two groups according to conization before radical surgery. One-to-one case–control matching was used to adjust the baseline characteristics. Results: A total of 332 patients were included after propensity matching (166, 50% in each group). Twenty-four of 166 (14.4%) and 142 of 166 (85.6%…
Consensus on performing skin biopsies, laboratory workup, evaluation of tissue samples and reporting of the results in patients with suspected cutane…
2014
Background Histopathological diagnosis including selection of lesions, the determination of the best point of time for biopsy and workup is not trivial in cutaneous graft-versus-host disease (GvHD). Objectives To develop interdisciplinary recommendations on performing, the laboratory work up and reporting of the results of skin biopsies in patients with suspected cutaneous GvHD. Methods A working group consisting of dermatopathologists, dermatologists, transplant-physicians and transplant-pathologists prepared recommendations for performing skin biopsies, laboratory workup and evaluation of tissue samples, and reporting of the results in patients with cutaneous GvHD. After achieving a conse…
