D-dimer testing: advantages and limitations in emergency medicine for managing acute venous thromboembolism

2007

Patients with suspected deep vein thrombosis (DVT) or pulmonary embolism (PE) are frequently admitted to an Emergency Department (ED) for initial evaluation. However, management of patients with suspicion of acute venous thromboembolism (VTE) in this clinical setting can be difficult; in fact symptoms and signs of DVT are non-specific and can be found in a broad spectrum of non-thrombotic disorders. An accurate and timely objective diagnosis is necessary for immediate and correct identification of patients with acute VTE, while avoiding the bleeding risk associated with unnecessary anticoagulant therapy in patients where DVT or PE have been ruled out. The diagnostic approach to patients wit…

Update on the principles and novel local and systemic therapies for the treatment of non-infectious uveitis.

2012

Ocular inflammatory disorders constitute a sight-threatening group of diseases that might be managed according to their severity. Their treatment guidelines experience constant changes with new agents that improve the results obtained with former drugs. Nowadays we can make use of a five step protocol in which topical, periocular and systemic corticosteroids remain as the main therapy for non-infectious uveitis. In addition, immunosuppresive drugs can be added in order to enhance the anti-inflammatory effects and to play the role of corticosteroid-sparing agents. These can be organized in four other steps: cyclosporine and methotrexate in a second one; azathioprine, mycophenolate and tacrol…

Recurrence quantification analysis as a tool for complex fractionated atrial electrogram discrimination

2012

International audience; Atrial fibrillation is the most encountered pathology of the heart rate. The reasons of its occurrence and its particular characteristics remain unknown, resulting from complex phenomena interaction. From these interactions emerges Complex Fractionated Atrial Electrograms (CFAE) which are useful for the ablation procedure. This study presents a method based on nonlinear data analysis, the Recurrence Quantification Analysis (RQA) applied on intracardiac atrial electrograms to detect CFAE particularities. The results obtained on areas previously tagged by a cardilogist show a good sensitivity to CFAE. Combination of RQA features offers a larger discrimination potential…

Triage assessment of registered nurses in the emergency department

2013

Standardised triage systems have been implemented in emergency departments (EDs) to improve the efficacy of assessment strategies as performed by registered nurses (RNs). However, the exact effect the standardised triage systems have on the decision-making process remains unclear.Aim: To evaluate decision making in the triage setting before and after implementation of the Medical Emergency Triage and Treatment System Adult in one hospital's ED.Methods: A descriptive intervention design with a quantitative approach. A total of 655 patients before and 413 patients after the intervention were included. A questionnaire was used to evaluate how the RNs assessed the patients before intervention w…

American Association Of Clinical Endocrinologists, American College Of Endocrinology, And Androgen Excess And Pcos Society Disease State Clinical Rev…

2015

Polycystic Ovary Syndrome (PCOS) is recognized as the most common endocrine disorder of reproductive-aged women around the world. This document, produced by the collaboration of the American Association of Clinical Endocrinologists (AACE) and the Androgen Excess and PCOS Society (AES) aims to highlight the most important clinical issues confronting physicians and their patients with PCOS. It is a summary of current best practices in 2015. PCOS has been defined using various criteria, including menstrual irregularity, hyperandrogenism, and polycystic ovary morphology (PCOM). General agreement exists among specialty society guidelines that the diagnosis of PCOS must be based on the presence o…

Controlled Ovarian Stimulation Induces a Functional Genomic Delay of the Endometrium with Potential Clinical Implications

2008

Context: Controlled ovarian stimulation induces morphological, biochemical, and functional genomic modifications of the human endometrium during the window of implantation. Objective: Our objective was to compare the gene expression profile of the human endometrium in natural vs. controlled ovarian stimulation cycles throughout the early-mid secretory transition using microarray technology. Method: Microarray data from 49 endometrial biopsies obtained from LH+1 to LH+9 (n = 25) in natural cycles and from human chorionic gonadotropin (hCG) +1 to hCG+9 in controlled ovarian stimulation cycles (n = 24) were analyzed using different methods, such as clustering, profiling of biological processes…

Sistema inteligente para protocolizar el diagnóstico de invasión ganglionar en el cáncer de laringe

2002

Laryngeal carcinoma is the most frequent malignant tumour in head and neck. Node invasion is known to be one of the most important prognostic factors. The aim of this study has been to design an intelligent system to perform a diagnostic algorithm of metastasic neck nodes. 122 clinical reports of patients diagnosed of laryngeal carcinoma in our department have been reviewed. The compiled data have been: tumor site, T stage, N stage (clinical, after CT scan and post-surgery). The method used to design the intelligent system has been the ID3, which is able to generate a minimal decision tree. Palpation has been the variable that has given more information about node invasion. CT has proved to…

Re-interpreting complex atrial tachycardia maps using global atrial vectors.

2021

Activation maps of scar-related atrial tachycardias (AT) can be challenging to interpret due to difficulty in inaccurate annotation of electrograms, and an arbitrarily predefined mapping window. A novel mapping software integrating vector data and applying an algorithmic solution taking into consideration global activation pattern has been recently described (Coherent™, Biosense Webster "Investigational").We aimed to assess the investigational algorithm to determine the mechanism of AT compared with the standard algorithm.This study included patients who underwent ablation of scar-related AT using the Carto 3 and the standard activation algorithm. The mapping data were analyzed retrospectiv…

A method of reconstruction after pancreaticoduodenectomy for pancreatic malignancies in very young children: Two cases reports

2016

Abstract Pancreatic tumors are very rare diseases in very young children. Most information about those diseases in children was published in cases reports. Due to the rare nature of pancreatic tumors in children, there remains the absence of diagnostic algorithms, clear radiographic and morphological assessments as well as evidence based best treatment options. Because of the young age of patients and the rare occurrence of pancreatic neoplasms, tumor detection remains poor. For malignancies affecting the head of the pancreas the only possibility for achieving clear surgical margins is performing a pancreaticoduodenectomy (PD). We describe two cases of diagnostic and treatment of pancreatic…
