Dacryocystorhinostomy (DCR) is the gold standard in treatment of patients with acquired naso lacrimal duct obstruction [1,2]. It consists of the marsupialisation of the lacrimal sac into the nasal fossa after creating an osteotomy opposite the common canalicula [2]. It can be done either under general or local anaesthesia, depending on the choice of the surgeon or the general condition of patie...

PURPOSE The purpose of this study was to evaluate the results of a teamwork revision endoscopic dacryocystorhinostomy (DCR) in eyes with previously failed external DCR. METHODS This retrospective study was performed on 50 failed external DCR subjects who underwent a teamwork revision endoscopic DCR by an ophthalmologist and an otolaryngologist. Paranasal sinus CT scanning was performed for ea...

A distributed cooperative coverage algorithm DCR is presented which is derived from an earlier complete single-robot algorithm, CCR. DCR executes independently on each robot in a team where the individual robots do not know the initial locations of their peers and applies to systems of robots operating in a rectilinear environment that use only intrinsic contact sensing to determine the boundar...

Bacillus thuringiensis produces toxins that target invertebrates, including Caenorhabditis elegans. Virulence of Bacillus strains is often highly specific, such that B. thuringiensis strain DB27 is highly pathogenic to C. elegans but shows no virulence for another model nematode, Pristionchus pacificus. To uncover the underlying mechanisms of the differential responses of the two nematodes to B...

Introduction: Since the days of Hippocrates, many modifications have been proposed in endonasal dacrocystorhinostomy (DCR), with the use of new drugs and implants showing variable results. The objective of this study was to analyze whether the use of silicon tubing or mitomycin C administration has an added advantage over conventional endonasal DCR.  Materials and Methods: A randomized controll...

In this paper we describe the most recent work within ISO TC37/SC 4, and in particular the development of a Data Category Registry (DCR) component of the Linguistic Annotation Framework. The DCR will contain a formally defined set of linguistic categories in common use within the language engineering community for reference and use in linguistically annotated resources. We outline the first pro...

BACKGROUND Epiphora is a common complaint of nasolacrimal duct obstruction (NLDO) in adults. The precise pathogenesis of NLDO is still unknown, but inflammatory processes are believed to be predisposing factors. Endoscopic dacryocystorhinostomy (EN-DCR) is an effective surgical technique for treating symptomatic NLDO. The purpose of the procedure is to relieve the patient's symptoms by creating...

The DCR methodology is a framework that proposes a generic and detailed evaluation of spoken dialog systems. We have already detailed (Antoine et al., 1998) the theoretical bases of this paradigm. In this paper, we present some experimental results on spoken language understanding that show the feasibility and the reliability of the DCR evaluation as well as its ability to provide a detailed di...

PURPOSE To compare the spiral computed tomographic dacryocystography (CT-DCG) findings of failed and successful dacryocystorhinostomies (DCR) and to detect the possible causes of failure before reoperation. METHODS Eighteen patients with failed and 15 patients with functional DCR were examined by spiral CT-DCG, a combination of contrast dacryocystography and spiral computed tomography. Radiol...
