Use of contemporary technologies and new materials in undergraduate Endodontics teaching.

2021

Background: This study aims to analyze the use of contemporary technologies and materials in undergraduate endodontic teaching in Spain. Material and Methods: The survey was sent to the undergraduate endodontic programme leads in the 23 Spanish dental schools. The survey asked about the use of magnification, ultrasonic devices, electronic apex locator, rotary instruments, root-filling techniques, and bioceramic cements in the teaching of endodontics. Results: The response rate was 91%, and the final number of schools included in the study was twenty. Only two schools (10%) used magnification (loupes or operative microscope). Five schools (25%) used ultrasonic devices to prepare the access c…

Dissociation of airway responsiveness and bronchoalveolar lavage (BAL) cell composition in sensitized guinea-pigs after daily inhalation of ovalbumin

1994

Summary. The association between inflammatory cell influx, cell activation status and change of airway responsiveness to acelylcholine (ACh) after daily inhalation of ovalbumin (OA) in sensitized guinea–pigs was investigated. Starting 3 weeks after sensitization (OA at 50mg/kg s.c. + i.p.) guinea–pigs were exposed daily to 2% OA (10min: undercover of 0.5Smg/kg mepyramine i.p. 15min before OA) for 2 weeks. Concentration–response curves (CRCs) for inhaled ACh were performed 24 h after the last OA–challenge and 24 h after another single OA–inhalation 1 week later. CRCs for inhaled ACh were neither affected 24 h after the last OA challenge (daily for two weeks) nor 24 h after another OA–inhalat…

Worldwide Techniques and Outcomes in Robot-assisted Minimally Invasive Esophagectomy (RAMIE): Results From the Multicenter International Registry

2022

OBJECTIVE: This international multicenter study by the Upper GI International Robotic Association aimed to gain insight in current techniques and outcomes of RAMIE worldwide.BACKGROUND: Current evidence for RAMIE originates from single-center studies, which may not be generalizable to the international multicenter experience.METHODS: Twenty centers from Europe, Asia, North-America, and South-America participated from 2016 to 2019. Main endpoints included the surgical techniques, clinical outcomes, and early oncological results of ramie.RESULTS: A total of 856 patients undergoing transthoracic RAMIE were included. Robotic surgery was applied for both the thoracic and abdominal phase (45%), o…

Surgical robotics for esophageal cancer

2018

We present an update on robotic techniques and their advantages and use in esophageal cancer surgery. Recent work has shown tremendous progress in robotic-assisted minimally invasive esophagectomy (RAMIE) and lymphadenectomy for esophageal cancer, as well as benefits of robotic surgery in high upper esophageal tumors and T4b disease. We discuss the different RAMIE techniques, especially for intrathoracic anastomosis. The ongoing ROBOT trial had demonstrated superiority of robotic esophageal cancer surgery over open esophagectomy. There are various putative technical advantages of RAMIE over minimally invasive esophagectomy, which need to be proven in future trials.

Robot-assisted and conventional minimally invasive esophagectomy are associated with better postoperative results compared to hybrid and open transth…

2021

BACKGROUND Currently 4 surgical techniques are performed for transthoracic esophagectomy (open esophagectomy (OE), hybrid esophagectomy (HE), conventional minimally invasive esophagectomy (MIE) and robot assisted minimally invasive esophagectomy (RAMIE). Aim of this study was to compare these 4 different esophagectomy approaches regarding postoperative complications and short term oncologic outcomes. METHODS Between 2008 and 2019, consecutive patients who underwent esophagectomy with gastric conduit reconstruction were included in this single center study. The primary outcome of this study was the incidence of postoperative complications. RESULTS Overall 422 patients (OE (n = 107), HE (n = …

European evidence based consensus for endoscopy in inflammatory bowel disease.

2013

Endoscopy plays an essential role in the diagnosis, management, prognosis, and surveillance of inflammatory bowel disease (IBD), but surprisingly there are few available guidelines.1,2 This prompted the ECCO Guidelines Committee (GuiCom) members to promote a Consensus on the appropriate indication and application of different endoscopic modalities in IBD. Since the development of guidelines is an expensive and time-consuming process, this Consensus may help to avoid duplication of effort in the future. It may also identify issues where the evidence is lacking and controlled studies are awaited. The strategy to reach the Consensus involved five steps: 1. Two members of the GuiCom (VA and RE)…

ObjectiveTo assess the safety and efficacy of epigallocatechin-3-gallate (EGCG) add-on to glatiramer acetate (GA) in patients with relapsing-remitting multiple sclerosis (RRMS).MethodsWe enrolled patients with RRMS (aged 18–60 years, Expanded Disability Status Scale [EDSS] score 0–6.5), receiving stable GA treatment in a multicenter, prospective, double-blind, phase II, randomized controlled trial. Participants received up to 800 mg oral EGCG daily over a period of 18 months. The primary outcome was the proportion of patients without new hyperintense lesions on T2-weighted (T2w) brain MRI within 18 months. Secondary end points included additional MRI and clinical parameters. Immunologic eff…

Depression, emotional blunting, and akinesia in schizophrenia

2002

Depression, negative symptoms, and extrapyramidal signs (EPS) frequently occur together in schizophrenia. Their overlap is due partly to the lack of specificity of assessment instruments. However, to disentangle the three syndromes is clinically important as treatment of schizophrenia requires a differentiated approach. This study investigated the overlap between depression, emotional blunting as a core part of the negative syndrome, and akinesia as manifestation of EPS, using the Calgary Depression Rating Scale (CDSS), the Rating Scale for Emotional Blunting (SEB), and the akinesia score of the Simpson-Angus Scale (SAS) as the most specific assessment instruments presently available. We in…

Predictive factors of severity and persistence of oropharyngeal dysphagia in sub-acute stroke.

2020

Purpose: This study aims to understand the factors contributing to the severity of oropharyngeal dysphagia and its persistence in the sub-acute phase of stroke. Methods: We retrospectively collected the data of all the patients suffering from a stroke in the last year. The severity of stroke was reported according to the NIHSS score. All the patients were evaluated with the Dysphagia Risk Score and with a FEES. We classified the Dysphagia Risk Score and FEES results using the PAS score and ASHA-NOMS levels. The data were analysed statistically with ANOVA test, Student’s t test and Pearson’s correlation coefficient. Results: A series of 54 patients were evaluated. The ANOVA test did not find…
