Metastatic Versus Osteoporotic Vertebral Fractures on MRI: A Blinded, Multicenter, and Multispecialty Observer Agreement Evaluation.

2020

Background: MRI is assumed to be valid for distinguishing metastatic vertebral fractures (MVFs) from osteoporotic vertebral fractures (OVFs). This study assessed (1) concordance between the image-based diagnosis of MVF versus OVF and the reference (biopsy or follow-up of >6 months), (2) interobserver and intraobserver agreement on key imaging findings and the diagnosis of MVF versus OVF, and (3) whether disclosing a patient’s history of cancer leads to variations in diagnosis, concordance, or agreement. Patients and Methods: This retrospective cohort study included clinical data and imaging from 203 patients with confirmed MVF or OVF provided to 25 clinicians (neurosurgeons, radiologists…

Prevention of feeding tube dislodgement with the Wiesbaden rein: a case series.

2009

We describe initial experience with the use of a new fixation method (Wiesbaden rein), which has been developed to prevent dislodgement of feeding tubes in the gastrointestinal tract. The Wiesbaden rein has been used in three patients without complication. In none of the patients was dislodgement or malfunction of the feeding tube observed. Therefore, the use of the Wiesbaden rein might prevent dislodgement of feeding tubes. Clinical trials are required before this new method can be recommended for general use.

Limitations of nasal nitric oxide as a screening method of primary ciliary dyskinesia in childhood

2016

Introduction: Nasal nitric oxide (nNO) has been proposed as a screening tool for primary ciliary dyskinesia (PCD). However, there are no reference values by age in consensus guidelines. Objectives: 1) To analyze differences in nNO among a group of patients with PCD and healthy controls. 2) To determine the proportion of pediatric PCD patients with nNO values similar to healthy population. Methods: Determination of nNO by electrochemical system (NIOX Vario®) in patients with DCP (diagnosis confirmed by digital high speed videomicroscopy) and healthy controls (without asthma, rhinitis or atopic dermatitis), aged between 7 and 60 years. Results: 32 patients (17 children, 53.1%) and 32 controls…

Heavy and Light Chain Monitoring in High Risk Smoldering Multiple Myeloma Patients Included in the GEM-CESAR Trial: Comparison with Conventional and …

2019

Introduction: The GEM-CESAR trial is a potentially curative strategy for high-risk smoldering multiple myeloma (HRsMM) patients (pts) in which the primary endpoint is the achievement of bone marrow minimal residual disease (MRD) negativity. However, other methods of disease evaluation in serum such as heavy+light chain (HLC) assessment, with a potential complementary value to the IMWG response criteria, have also been tested. Aim: To evaluate the performance of HLC assay in HRsMM pts at diagnosis and after consolidation, comparing the results with standard serological methods and Next Generation Flow (NGF) for the assessment of bone marrow MRD. Patients and Methods: Ninety HRsMM pts include…

The effect of conventional movement training and trampoline training on balance and gait in chronic hemiplegic patients

1991

The postural sway of subjects during standing both with their eyes open and closed together with maximum velocity of walking were analysed in six male chronic hemiplegic patients before, during and after an intensive movement training programme lasting 8 weeks. The movement training programme was carried out on the basis of Bobath's principles. Three of the subjects carried out their training on a trampoline, with the particular purpose of enhancing the stimulation of the mechanisms responsible for the control of balance. During the follow-up, maximal walking velocity remained at previous levels and no systematic changes were observed in the control of postural sway. Although the use of the…

Directly measured and self-reported physical activity in a sample of Finnish secondary school students

2012

Previous studies based on self-reports show that a majority of children and adolescents in Western countries fail to achieve the recommendation of 60 minutes moderate to vigorous physical activity (PA) on a daily basis. The specific aim of the study was to analyze the relationship between directly measured and self-reported PA in a cross-sectional sample of Finnish secondary school students. Moreover, how large proportion of adolescents accumulate at least 60 minutes of moderate to vigorous PA on a daily basis using self-reports and direct measure scores. Methods: Participants were recruited from a secondary school located in Northeast Finland. The sample comprised 96 students (58 girls, 38…

The acceptability of an Internet-based self-help treatment for fear of public speaking

2009

ABSTRACT Several randomised controlled studies have shown the efficacy of Internet-based self-help treatments. These studies have centred their attention on axis I (efficacy) of the Guidelines for Empirically Validated Treatments, although there are a few studies that also take into account axis II (effectiveness). The aim of the present work was to test the acceptability of an Internet-based self-help program for fear of public speaking and to compare its acceptability with the same treatment administered by a therapist. Fifty-two participants suffering from social phobia were randomly selected to take part in one of these treatments. All participants reported being satisfied with the trea…

Modeling the pelvic region for non-invasive pelvic intraoperative neuromonitoring

2016

Abstract Finite element analysis (FEA) of electric current distribution in the pelvis minor may help to assess the usability of non-invasive surface stimulation for continuous pelvic intraoperative neuromonitoring. FEA requires generation of quality volumetric tetrahedral mesh geometry. This study proposes the generation of a suitable mesh based on MRI data. The resulting volumetric mesh models the autonomous nerve structures at risk during total mesorectal excision. The model also contains the bone, cartilage, fat, skin, muscle tissues of the pelvic region, and a set of electrodes for surface stimulation. The model is ready for finite element analysis of the discrete Maxwell’s equations.
