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…

Common etiological pathways between toxic substance use, Internet and cybersex addiction: The role of expectancies and antisocial deviance proneness

2016

This study examined Internet and cybersex addiction in adolescents and how such behaviour was associated with substance use (in particular, cigarettes, alcohol, and drug use). Participants were 312 adolescents, aged 14-16, who completed survey instruments. Study measures included demographic, toxic substance use, expectancies toward substances consumption, antisocial deviance proneness, Internet, and cybersex addiction variables. Descriptive, bivariate analyses, exploratory/confirmatory factor analyses, and structural Equation Modeling were performed. Nearly 60%, 26%, and 25% of adolescents reported having drunk alcohol, used drugs and smoked cigarettes respectively. Prevalence of Internet …

Impact of an intensive education programme of diagnostic lung and lower limb ultrasound on physiotherapist knowledge: A pilot study.

2021

INTRODUCTION/PURPOSE: Diagnostic ultrasound of the respiratory system and peripheral muscular systems is increasingly being used by clinicians. The aim of this study was to evaluate the knowledge outcomes of a bespoke one‐day curriculum for physiotherapists that incorporated lung, diaphragm and lower limb muscle diagnostic ultrasound theory and practical training in image acquisition and analysis. METHODS: A one‐day course comprised of three instructors and 32 participants on key diagnostic ultrasound findings of the lungs, diaphragm and lower limb musculature included didactic lectures combined with expert‐led hands‐on training in practical sessions. Participants undertook pre‐ and post‐co…

Computertomographische Funktionsuntersuchung der Lunge nach einseitiger Lungentransplantation mit axialer und koronarer Akquisition

1996

After single-lung transplantation in a patient suffering from obstructive emphysema lung function parameters worsened during follow-up. To complement the routine high-resolution CT (HRCT) scans acquired in inspiration, additional scans were obtained to evaluate regional lung function. The comparison of HRCT scans acquired in inspiration and in expiration revealed different ventilation conditions of both lungs, continuous acquisition in a single slice (dynamic multiscan acquisition) in the axial and coronal plane demonstrated mediastinal shifting and the movement of the diaphragm during the whole breathing cycle. Both modalities can provide important information concerning regional differenc…

Academic competence, teacher–student relationship, and violence and victimisation in adolescents: The classroom climate as a mediator

2021

School violence is a serious social and public health problem prevalent worldwide. Although the relevance of teacher and classroom factors is well established in the literature, few studies have focused on the role of teacher perceptions in school violence and victimisation and the potential mediational role of classroom climate in this relationship. A total of 2399 adolescents (50% girls), aged between 11 and 18 years (M = 14.65, SD = 1.78) and enrolled in five Spanish Secondary Compulsory Education schools completed measures of classroom climate, school violence towards peers and perception of peer victimisation, and their teachers informed about their academic competence and the teacher&…

Training program for transanal endoscopic microsurgery.

1988

Televised endoscopy and the concept of the “assisted” endoscopic operation is of great help in teaching surgical endoscopic techniques. The use of training dummies provides a new method of training manual dexterity and surgical skills in special courses or in surgical skill laboratories. We have developed a training system for transanal endoscopic microsurgery. Operations with our technique were performed on 116 patients. Like other microsurgical techniques, our method requires a special introduction and intensive training. This paper presents our multistage, video-supported training course for teaching transanal endoscopic microsurgery. The one-day training session is divided into four ste…

The Short Demoralization Scale (SDS): A new tool to appraise demoralization in palliative care patients.

2017

ABSTRACTObjective:The Demoralization Scale (DS) is the most widely used measure for assessing demoralization. Following the recent clamor for brief assessment tools, and taking into account that demoralization has proved to be a symptom that needs to be controlled and treated in the palliative care setting, a shorter scale is needed. The aim of the present research is to introduce and evaluate the Short Demoralization Scale (SDS).Method:We employed a cross-sectional design that included a survey of 226 Spanish palliative care patients from the Hospital General Universitario de Valencia. We employed the SDS, the DS, and the Hospital Anxiety and Depression Scale (HADS).Results:The confirmator…

A Novel Technique of Posterolateral Suturing in Thoracoscopic Diaphragmatic Hernia Repair

2017

Background Closure of the posterolateral defect in some cases of congenital diaphragmatic hernia (CDH) can be difficult. Percutaneous transcostal suturing is often helpful to create a complete, watertight closure of the diaphragm. A challenge with the technique is passing the needle out the same tract that it entered so that no skin is caught when the knots are laid down into the subcutaneous tissue. This report describes a novel technique using a Tuohy needle to percutaneously suture the posterolateral defect during thoracoscopic repair of CDH. Case We report a case of a 6-week-old infant who presented with a CDH and ipsilateral intrathoracic kidney that was repaired using thoracoscopic a…
