Canal transportation caused by a new instrumentation technique and three standard techniques
1996
The ability of three different enlarging techniques (balanced force concept, step-back, and recapitulation) and a prototype system to maintain the original canal path during root canal preparation were compared, in vitro, with a theoretical ideally prepared root canal. Measurements were made at the concave and convex sides of the canal at four different levels (1, 4, 5, and 7 mm from apical, respectively). Simulated root canals embedded in clear casting resin and an enlarging computer-supported device were used for this study. The results showed that none of the enlarging techniques used in this study was able to prepare a canal ideally. The prototype system, at level 1, showed an ideal amo…
Intravenöse Eisensubstitution bei chronischer Erkrankung – bei wem, wann und wie?
2019
ZusammenfassungIn den letzten Jahren konnten wesentliche Fortschritte in der Erkennung und Behandlung des Eisenmangels erzielt werden, deren Ergebnisse auch für viele Fachgebiete und insbesondere mit Patienten mit chronisch-entzündlichen Erkrankungen relevant sind. Allerdings wird in der täglichen Praxis ein Eisenmangel vielfach nicht identifiziert und konsequent therapiert.Ein Eisenmangel kann – auch bevor eine Anämie auftritt – die Lebensqualität einschränken und den Verlauf der Grunderkrankung beeinflussen. Bei Patienten mit chronischen Erkrankungen sollte der Eisenstatus regelmäßig erfasst werden. Gerade bei Patienten mit chronisch-entzündlichen Erkrankungen sind die derzeit verfügbaren…
Stability of Ascorbic Acid in Several Blood Collecting Procedures
2003
Purpose: There is good evidence that ascorbic acid (AA) status influences the onset of post-operative complications in intensive care patients. Light and room temperature cause the spontaneous oxidation of AA. Therefore, the stability of AA during modified sample preparation was investigated. Design: Prospective, single centre study. Methods: The AA plasma concentration was analysed in arterial and venous blood with added ethylene-diamine-tetra-acetic acid (EDTA) from 165 subjects. In addition, EDTA or heparin was added as an anticoagulant in venous blood of 79 subjects. Analyses were carried out using high performance liquid chromatography with ultraviolet detection. Results: In samples of…
Insomnia in obsessive-compulsive disorder: A Swedish population-based cohort study.
2020
Abstract Background The association between specific psychiatric disorders and insomnia is well established, but the prevalence of insomnia in obsessive-compulsive disorder (OCD) is unknown. This population-based study examined the prevalence of insomnia in patients with OCD compared to unaffected individuals from the general population and to their unaffected full siblings, and evaluated the contribution of psychiatric comorbidities to this association. Methods Individuals diagnosed with OCD (31,856) were identified from a cohort of 13,017,902 individuals living in Sweden anytime during 1973 and 2013. Logistic regression analyses were used to investigate the odds of insomnia in individuals…
Einsatz des intraoperativen Ultraschalls in der Speicheldrüsenchirurgie
2006
Sonography of the head-and-neck region is well established in the preoperative diagnostic process of tumorous lesions. Its intraoperative use to localise small tumours, however, has been rarely investigated to date. We applied intraoperative ultrasound to 19 patients who underwent parotid surgery and evaluated the following criteria: intraoperative tumour presentation, scan quality, comparison between sonographic visualisation and tumour detection by palpation, histological tumour borders as well as postoperative complications. All lesions were reproduceable by intraoperative ultrasound and could be demonstrated in sufficient quality. None of the 19 parotid tumours could be identified by pa…
Best practices and recommendations for drug regimens and plasma exchange for immune thrombotic thrombocytopenic purpura.
2021
Introduction Thrombotic thrombocytopenic purpura (TTP) is a life-threatening thrombotic microangiopathy characterized by microangiopathic hemolytic anemia, thrombocytopenia, and organ injury. TTP pathophysiology is based on a severe ADAMTS13 deficiency, and is a medical emergency with fatal outcome if appropriate treatment is not initiated promptly. Areas covered Authors will review the best options currently available to minimize mortality, prevent relapses, and obtain the best clinical response in patients with immune TTP (iTTP). Available bibliography about iTTP treatment has been searched in Library's MEDLINE/PubMed database from January 1990 until April 2021. Expert opinion The general…
Implementation of a strategy involving a multidisciplinary mobile unit team to prevent hospital admission in nursing home residents: protocol of a qu…
2020
IntroductionNursing home residents represent a particularly vulnerable population experiencing high risk of unplanned hospital admissions, but few interventions have proved effective in reducing this risk. The aim of this research will be to verify the effects of a hospital-based multidisciplinary mobile unit (MMU) team intervention delivering urgent care to nursing home residents directly at their bedside.Methods and analysisFour nursing homes based in the Parma province, in Northern Italy, will be involved in this prospective, pragmatic, multicentre, 18-month quasiexperimental study (sequential design with two cohorts). The residents of two nursing homes will receive the MMU team care int…
Simulated root canals preparation time, comparing ProTaper Next and WaveOne Gold systems, performed by an undergraduate student
2020
Background: The aim of this study was to compare the WaveOne Gold and ProTaper Next systems regarding the time spent preparing simulated canals performed by an inexperienced student. Material and Methods: 80 simulated L-shaped canals were randomly divided into two groups (n = 40) and numbered in order of instrumentation. Canals were instrumented with WaveOne Gold (group 1) and ProTaper Next (group 2) systems. The effective instrumentation time and the number of instrumentation cycles were recorded. All procedures were performed by the same operator. Statistical analysis was obtained by the Mann-Whitney, Kruskal-Wallis test with significance of p <0.05. Results: There were no statistically s…
Survey of root canal irrigating solutions used in dental practices within Germany.
2014
Aim Irrigant usage information in relation to years of professional experience was collected from general dentists in different German federal states by means of a questionnaire. Methodology A short survey concerning endodontic treatment and use of irrigants was mailed to 4240 dentists or delivered to 3720 dental offices as an extra page in a journal in eight German states. Detailed information concerning the most frequently used irrigants, their concentrations, the spectrum of disinfectants used in root canal treatment concepts for vital and nonvital pulps, main topics of continuing education as well as years of professional experience was collected. The statistical analysis of differences…
The timing of introduction of pharmaceutical innovations in seven European countries
2014
RATIONALE, AIMS AND OBJECTIVES: Differences in the performance of medical care may be due to variation in the introduction and diffusion of medical innovations. The objective of this paper is to compare seven European countries (United Kingdom, the Netherlands, West Germany, France, Spain, Estonia and Sweden) with regard to the year of introduction of six specific pharmaceutical innovations (antiretroviral drugs, cimetidine, tamoxifen, cisplatin, oxalaplatin and cyclosporin) that may have had important population health impacts. METHODS: We collected information on introduction and further diffusion of drugs using searches in the national and international literature, and questionnaires to …
