Recognition of Root Canal Orifices in Video Sequences as a Future Support System During Endodontic Treatment

2009

Abstract Introduction The objective of this study was to show the practical application of computer-aided techniques for detecting root canal orifices through the access cavity using a video camera mounted on a microscope. Methods A minimum distance classification image recognition algorithm was tested in an in vitro study to assess the possibilities of computer-aided recognition of root canal orifices. A Motic DM143 digital stereo microscope (Motic Germany GmbH, Wetzlar, Germany) was used because it includes a video camera that can be connected via USB1.1 to any computer. Results The newly developed software is capable of communicating with a video camera and can automatically detect the r…

Nitric oxide production and endothelium-dependent vasorelaxation ameliorated by N1-methylnicotinamide in human blood vessels.

2012

N 1 -methylnicotinamide (MNA + ) has until recently been thought to be a biologically inactive product of nicotinamide metabolism in the pyridine nucleotides pathway. However, the latest observations imply that MNA + may exert antithrombotic and anti-inflammatory effects through direct action on the endothelium. We examined both in vivo and in vitro whether the compound might induce vasorelaxation in human blood vessels through the improvement of nitric oxide (NO) bioavailability and a reduction of oxidative stress mediated by endothelial NO synthase (eNOS) function. MNA + treatment (100 mg/m 2 orally) in healthy normocholesterolemic and hypercholesterolemic subjects increased the l-argini…

The Rorschach method for obesity assessment: clinical study on a group of obese women

2018

SUMMARY. Aim. The purpose of this study is to explore through the Rorschach method the psychological and personological profile of the woman with obesity. Methods. The Rorschach test was administered to 10 women with body mass index of 41.86±9.9 kg/m2 at the clinic for obesity surgical treatment at the University Hospital “Paolo Giaccone” of Palermo. Results. The quantitative and qualitative analysis of the Rorschach responses detected in the study show: limited practical and creative sense in managing daily life situations, rigid control of emotions, affective turmoil, sense of inadequacy; sufficient examination of reality and adaptation social. Conclusion. The Rorschach method can be the …

Neural correlates of antinociception in borderline personality disorder.

2006

Context A characteristic feature of borderline personality disorder (BPD) is self-injurious behavior in conjunction with stress-induced reduction of pain perception. Reduced pain sensitivity has been experimentally confirmed in patients with BPD, but the neural correlates of antinociceptive mechanisms in BPD are unknown. We predicted that heat stimuli in patients with BPD would activate brain areas concerned with cognitive and emotional evaluation of pain. Objective To assess the psychophysical properties and neural correlates of altered pain processing in patients with BPD. Design Case-control study. Setting A university hospital. Participants Twelve women with BPD and self-injurious behav…

Prenatal and postnatal residential usage of insecticides in a multicenter birth cohort in Spain

2013

Abstract: This study aimed to describe the residential use of insecticides in a birth cohort in Spain. Study subjects were 2 456 women enrolled into the INMA (Environment and Childhood) birth cohort followed prospectively during pregnancy and in the early postnatal period. The women were recruited at the beginning of their pregnancy between 2003 and 2008 in four regions of Spain. Socio-demographic, environmental and lifestyle information was obtained at two interviews during pregnancy, one at the first (mean:13.8 +/- 2.6 weeks of gestation) and the other at the third trimester (mean: 33.3 +/- 23 weeks of gestation). Information about prenatal use of indoor and outdoor insecticides (type, ti…

Consistencies and discrepancies in self- and observer-rated anxiety scales. A comparison between the self- and observer-rated Marks-Sheehan scales.

1990

The Marks-Sheehan anxiety scales are the only scales where self-ratings and observer ratings are perfectly matched by the number, the content and the scaling of the items. Therefore these scales are an excellent tool to investigate the compatibility and to study different structures in self- and observer ratings. This was done by using the data material on the Marks-Sheehan scales of the Cross National Collaborative Panic Study. In this study 1168 outpatients who met the DSM-III criteria for panic disorder were randomly allocated either to alprazolam, imipramine or placebo treatment. Our results show that the Marks-Sheehan scales are highly comparable to other established rating scales. Bot…

Self- and observer assessment in anxiolytic drug trials: A comparison of their validity

1990

Self-rating scales are considered to be less useful for comparing different treatments in anxiety patients than observer-rating scales. However, the empirical evidence for this assumption is not adequate. A self-rating inventory of 35 items related to anxiety was perfectly parallel with an observer-rating inventory. Both instruments were used in the Cross National Collaborative Panic Study to compare the efficacy of imipramine, alprazolam and placebo in an 8-week drug trial in a sample of 1168 outpatients. The variance of the self-rating assessments was about two times higher. Both scales were equally sensitive to change; however, the measurement of change by means of the self-rating scale …

SQ HDM SLIT-tablet (ALK) in treatment of asthma – Post hoc results from a randomised trial

2014

SummaryIntroductionIn a double-blind, placebo-controlled trial (EudraCT identifier: 2006-001795-20), the standardised quality (SQ) house dust mite (HDM) sublingual immunotherapy (SLIT)-tablet (ALK, Denmark) was investigated.MethodThe trial included 604 subjects, ≥14 years, with mild-moderate HDM allergic asthma. Subjects were randomised 1:1:1:1 to 1, 3 or 6 SQ-HDM or placebo once daily. The primary endpoint was reduction in inhaled corticosteroid (ICS) after one year. ICS reduction, asthma quality of life questionnaire (AQLQ) and asthma control questionnaire (ACQ) score was analysed post hoc in a subgroup with daily ICS use of 400–800 μg and ACQ score of 1–1.5, corresponding to partly contr…

Omalizumab (Xolair®) improves quality of life in adult patients with allergic asthma: a review

2003

Abstract Physicians are increasingly aware that asthma causes significant impairment of the patient's physical, psychological, and social well-being. Whilst standard clinical endpoints provide significant information on airway status during treatment, it is important to determine whether such improvements overcome the functional impairment that patients have to deal with on a daily basis. As such, assessment of health-related quality of life (QoL) is an important aspect of asthma management in clinical practice. Omalizumab (Xolair ® ) is a recombinant humanized monoclonal anti-immunoglobulin E (IgE) antibody that represents a new therapeutic approach to IgE-mediated diseases such as allergi…

Risk of low bone mineral density and low body mass index in patients with non-celiac wheat-sensitivity: a prospective observation study.

2014

Background Non-celiac gluten sensitivity (NCGS) or ‘wheat sensitivity’ (NCWS) is included in the spectrum of gluten-related disorders. No data are available on the prevalence of low bone mass density (BMD) in NCWS. Our study aims to evaluate the prevalence of low BMD in NCWS patients and search for correlations with other clinical characteristics. Methods This prospective observation study included 75 NCWS patients (63 women; median age 36 years) with irritable bowel syndrome (IBS)-like symptoms, 65 IBS and 50 celiac controls. Patients were recruited at two Internal Medicine Departments. Elimination diet and double-blind placebo controlled (DBPC) wheat challenge proved the NCWS diagnosis. A…
