Performance of a new device for the clinical determination of light discomfort
2020
PURPOSE To assess the performance of a new device for the clinical determination of light discomfort on a large sample of healthy human subjects. METHODS A total of 489 subjects ranging from 20 to 70 years old (241 men, 248 women) were evaluated with the LUMIZ™ 100 to determine light discomfort. Repeatability was assessed by means of within-subject standard deviation, coefficient of variation (CoV), and intraclass correlation coefficient (ICC). Repeated measures ANOVA, Kruskal-Wallis, and correlation analysis were applied to test for differences between repeated measures, and effect of age on reliability. RESULTS Discomfort thresholds obtained are well distributed across the light intensity…
Italian version of the Chicago multiscale depression inventory: translation, adaptation and testing in people with multiple sclerosis.
2004
Depression is the commonest psychiatric disturbance in people with multiple sclerosis (MS), with prevalence higher than in the general population and other chronic diseases. However, accurate assessment of depressive symptoms can be biased by somatic symptoms which are part of both MS and depression. We translated and adapted into Italian the Chicago multiscale depression inventory (CMDI) and assessed its acceptability, internal consistency and test-retest reliability in 213 MS outpatients and 213 individually matched healthy controls. The questionnaire was also tested in 32 people with major depression. Acceptability, internal consistency, and test-retest reliability were good overall. We …
Ten-year follow-up of health-related quality of life among ambulatory persons with multiple sclerosis at baseline
2016
Purpose The aim of this 10-year follow-up study was to determine changes in health-related quality of life (HRQoL) over time among ambulatory persons with MS (PwMS) at the baseline using generic and disease-specific instruments. Methods Of 109 independently walking PwMS included in a population-based study in 2002, 77 (70.6 %) were re-assessed in 2012. HRQoL was captured using the 36-Item Short Form Survey Instrument (RAND-36), 15D instrument (15D), and the Multiple Sclerosis Quality of Life-54 (MSQOL-54). Repeated-measures ANOVA and effect size (ES) calculations (Cohen’s d) were used in the statistical analysis. Results The RAND-36 physical health composite score (p = 0.003, ES = 0.26) and…
Comparison of partial coherence interferometry and ultrasound for anterior segment biometry.
2008
To assess the performance of a partial coherence interferometry (PCI)-based device for the determination of anterior segment biometry.Clinica Centrofama, Cartagena, Murcia, Spain.Central corneal thickness (CCT), anterior chamber depth (ACD), and lens thickness (LT) were measured with the ACMaster PCI anterior segment biometer and an Echoscan US-1800 ultrasound (US) biometer/pachymeter with and without cycloplegia. To determine the precision of the instruments, the same examiner took 30 consecutive CCT, ACD, and LT measurements in a single subject under the same conditions and with and without cycloplegia. The same measurements were performed in additional subjects.Twenty-one eyes (16 subjec…
BODY MASS INDEX DOES NOT CHANGE BEFORE PARKINSON'S DISEASE ONSET.
2008
Background and purpose: Previous studies on the association between Parkinson’s disease (PD) and body mass index (BMI) have reported conflicting results. We investigated the relationship between PD and BMI by a case–control study. Methods: PD patients were randomly matched to healthy individuals by sex and age. BMI distribution in cases has been compared with BMI of controls and odd ratios (ORs) with 95% CI were calculated. Results: We included 318 PD patients and 318 controls. We observed no association between PD and BMI. BMI distribution in cases and controls was similar also when we adjusted for diabetes, hypercholesterolemia and the time elapsed between PD onset and the interview (O…
Reduction of HbA1c levels following nonsurgical treatment of periodontal disease in type 2 diabetics
2009
Objectives: A study was made of the effect of nonsurgical periodontal treatment upon blood glucose control in type 2 diabetics with periodontal disease. Study design: A pre-post repeated measures analytical design was used, with a PubMed search of the related articles published up until December 2008. Results: The improvement in glycosylated hemoglobin (HbA1c) after nonsurgical periodontal treatment on comparing the baseline (8.0290±1.5539) and final values (7.7806±1.5636) was 0.2483±0.1171, and proved statistically significant (p=0.042). Conclusions: A decrease in HbA1c was observed after treatment, thus indicating improved blood glucose control in type 2 diabetics with periodontal disease.
Dysphagia Prevention in Anterior Cervical Discectomy Surgery: Results from a Prospective Clinical Study
2019
Background: Dysphagia is a common complication after anterior cervical discectomy surgery (ACDS). Recent studies have shown that reducing the endotracheal tube cuff pressure, local irrigation with methylprednisolone, and minimizing the pharynx/esophagus retraction can decrease the incidence of postoperative dysphagia after ACDS. This is the first study assessing the efficacy of all these 3 measures simultaneously. Methods: This prospective study included 35 patients (group 1) who underwent ACDS with the adoption of all the 3 preventive measures. Group 1 was compared with a homogenous group of 35 patients who underwent regular ACDS (group 2). Postoperative dysphagia and odynophagia were eval…
Assessment of Construct Validity of the Oswestry Disability Index and the Scoliosis Research Society–30 Questionnaire (SRS-30) in Patients With Degen…
2019
Observational cohort study.To measure and compare the structural validity of the Oswestry Disability Index (ODI) and the Scoliosis Research Society-30 (SRS-30) questionnaire in an adult population with prolonged degenerative thoracolumbar disease.The ODI and the SRS-30 are commonly used patient-reported outcome instruments to assess back-specific disability and symptoms related to scoliosis. Still, these instruments have not been validated for degenerative spinal disease with different stages of deformity.Altogether, 637 consecutive adult patients with degenerative spinal pathologies were included. The patients completed the ODI (version 2.0), the 23 preoperative items of the SRS-30, a gene…
Inter- and intrarater reliability of two proprioception tests using clinical applicable measurement tools in subjects with and without knee osteoarth…
2017
Abstract Background The therapeutic value of proprioceptive-based exercises in knee osteoarthritis (KOA) management warrants investigation of proprioceptive testing methods easily accessible in clinical practice. Objective To estimate inter- and intrarater reliability of the knee joint position sense (KJPS) test and knee force sense (KFS) test in subjects with and without KOA. Design Cross-sectional test-retest design. Method Two blinded raters performed independently repeated measures of the KJPS and KFS test, using an analogue inclinometer and handheld dynamometer, respectively, in eight KOA patients (12 symptomatic knees) and 26 healthy controls (52 asymptomatic knees). Intraclass correl…
Performance of the compensation comparison method for retinal straylight measurement: effect of patient's age on repeatability
2008
Aim: The assessment of repeatability and reproducibility of retinal straylight measurements with the C-Quant straylight meter (Oculus AG, Germany) and the effect of patient’s age on the instrument performance are tested with a series of experiments. Methods: First, 20 eyes from 20 subjects (mean age 26.9 (SD 2.7) years, mean refractive error −1.34 (2.72) D) were examined with the C-Quant straylightmeter, taking 10 consecutive readings. Five subjects were also examined on five consecutive days to assess reproducibility. Additionally, repeated measures of straylight from 84 subjects of ages ranging from 19 to 86 years (mean (SD): 42.4 (24.0) years) were retrospectively analysed to assess the …
