AIM To compare the outcomes of dacryocystorhinostomy (DCR) using traditional Crawford tubes (TCT) and Crawford tubes with suture (CTS) in the lumen. METHODS Retrospective case series consisting of patients who underwent DCR between 2008 and 2013. RESULTS A total of 61 DCRs were performed on 50 patients. Patients who underwent DCR using CTS had higher rates of prolapse compared to the TCT gr...

AIMS To utilise the improved optical qualities of newly developed lacrimal endoscopes and newly miniaturised laser fibres for diagnostic visualisation and laser surgery of the lacrimal system. METHODS A KTP laser (wavelength 532 nm, 10 W energy) was used for laser assisted dacryocystorhinostomy (DCR) with endolacrimal visualisation in 26 patients. Bicanalicular silicone intubation was placed ...

Context-aware recommender systems (CARS) adapt their recommendations to users’ specific situations. In many recommender systems, particularly those based on collaborative filtering, the contextual constraints may lead to sparsity: fewer matches between the current user context and previous situations. Our earlier work proposed an approach called differential context relaxation (DCR), in which d...

An abnormal increase in the SDE was observed for superconducting nanowire single-photon detectors (SNSPDs) when the bias current (I(b)) was close to the switching current (I(sw)). By introducing the time-correlated single-photon counting technique, we investigated the temporal histogram of the detection counts of an SNSPD under illumination. The temporal information helps us to distinguish phot...

BACKGROUND Drug use contributes to higher rates of morbidity and mortality among people who use drugs compared to the general population. In 2012, Danish politicians passed a law that allowed drug consumption rooms (DCRs) to operate; among the objectives were to improve the well-being of vulnerable citizens and to reduce the number of overdoses. Five Danish DCRs are currently being operated. Th...

Objective Comparison of endoscopic and external dacryocystorhinostomy (DCR) results and evaluation of patients' satisfaction. Methods Forty six (35 females and 11 males) patients who underwent endoscopic DCR and 43 (37 females and six males) who underwent external DCR were included. Surgical success was objectively and subjectively assessed. The nasolacrimal duct was irrigated by a saline sol...
