Effects of photodynamic therapy in periodontal treatment: A randomized, controlled clinical trial
2017
Aim To evaluate the effects of photodynamic therapy (PDT) in the nonsurgical treatment of chronic periodontitis. Materials and methods A randomized, single-blind, controlled, parallel-group clinical trial was performed. Sixty patients were enrolled: 20 healthy controls and 40 patients with periodontitis. The 40 patients were randomized for scaling and root planing (SRP) or SRP+PDT. Periodontal (plaque index, probing depth, clinical recession, clinical attachment level, bleeding on probing, and gingival crevicular fluid volume, corresponding to 381 vs 428 critical sites), microbiological (Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Treponema dentico…
Effect of incision design on interproximal bone loss of teeth adjacent to single implants. A randomized controlled clinical trial comparing intrasulc…
2018
PURPOSE To evaluate the effect of incision design in implant surgery on interproximal bone loss of posterior teeth adjacent to interdental single implants, comparing intrasulcular and paramarginal incision. A further aim was to assess the influence of the incision technique on peri-implant bone remodeling. MATERIALS AND METHODS A controlled randomized clinical trial was carried out in a University Clinic. All the patients received an interdental posterior single implant. The incision type was randomly divided into two groups: (a) intrasulcular or (b) paramarginal. Standardized periapical digital radiographs were made with the parallel technique and a silicone index individualized in each pa…
Contact dermatitis due to nickel allergy in patients suffering from non-celiac wheat sensitivity
2017
Background: Non‐celiac wheat sensitivity (NCWS) is a new clinical entity in the world of gluten‐related diseases. Nickel, the most frequent cause of contact allergy, can be found in wheat and results in systemic nickel allergy syndrome and mimics irritable bowel syndrome (IBS). Objective: To evaluate the frequency of contact dermatitis due to nickel allergy in NCWS patients diagnosed by a double‐blind placebo‐controlled(DBPC)challenge,and to identify the characteristics of NCWS patients with nickel allergy. Methods: We performed a prospective study of 60 patients (54 females, 6 males; mean age 34.1 ± 8.1 years) diagnosed with NCWS from December 2014 to November 2016; 80 age‐ and sex‐matched…
Tralokinumab did not demonstrate oral corticosteroid-sparing effects in severe asthma
2018
Long-term oral corticosteroid (OCS) use in patients with severe asthma is associated with significant adverse effects.This 40-week, randomised, double-blind trial evaluated the OCS-sparing potential of tralokinumab in patients with severe, uncontrolled asthma requiring maintenance OCS treatment plus inhaled corticosteroids/long-acting β2-agonists. Overall, 140 patients were randomised to tralokinumab 300 mg or placebo (n=70 in each group) administered subcutaneously every 2 weeks. The primary end-point was percentage change from baseline in average OCS dose at week 40, while maintaining asthma control. Secondary end-points included proportion of patients with a prescribed maintenance OCS do…
Tauroursodeoxycholic acid in the treatment of patients with amyotrophic lateral sclerosis
2015
Background and purpose: Tauroursodeoxycholic acid (TUDCA) is a hydrophilic bile acid that is produced in the liver and used for treatment of chronic cholestatic liver diseases. Experimental studies suggest that TUDCA may have cytoprotective and anti-apoptotic action, with potential neuroprotective activity. A proof of principle approach was adopted to provide preliminary data regarding the efficacy and tolerability of TUDCA in a series of patients with amyotrophic lateral sclerosis (ALS). Methods: As a proof of principle, using a double-blind placebo controlled design, 34 ALS patients under treatment with riluzole who were randomized to placebo or TUDCA (1 g twice daily for 54 weeks) were e…
Topical azithromycin for the prevention of Lyme borreliosis: a randomised, placebo-controlled, phase 3 efficacy trial
2017
Summary Background Lyme borreliosis develops in 1–5% of individuals bitten by ticks, but with a diagnostic gap affecting up to 30% of patients, a broadly applicable pharmacological prevention strategy is needed. Topical azithromycin effectively eradicated Borrelia burgdorferi sensu lato from the skin in preclinical studies. We assessed its efficacy in human beings. Methods In this randomised, double-blind, placebo-controlled, multicentre trial done in 28 study sites in Germany and Austria, adults were equally assigned to receive topical 10% azithromycin or placebo twice daily for 3 consecutive days, within 72 h of a tick bite being confirmed. Randomisation numbers, which were stratified by …
Application of tRNS to improve multiple sclerosis fatigue: a pilot, single-blind, sham-controlled study
2019
We evaluated the effects of transcranial random noise stimulation (tRNS) on fatigue in 17 subjects with relapsing–remitting multiple sclerosis with low physical disability. Two different patient groups underwent real or sham stimulation for 10 days, targeting the primary motor cortex of the dominant side or contralateral to the most compromised limb. In the ‘real group’, beneficial effects were observed using the Modified Fatigue Impact Scale (p = 0.04; physical subscale: p = 0.03), the subscales ‘change in health’ (p = 0.006) and ‘role limitations due to physical problems’ (p = 0.001) of the Multiple Sclerosis Quality of Life-54, and by assessing the patient impression of perceived fatigue…
Impact of hypertonic saline nebulisation combined with oscillatory positive expiratory pressure on sputum expectoration and related symptoms in cysti…
2018
Abstract Objective To evaluate the impact of combining nebulised hyaluronic acid plus hypertonic saline (HA + HS) with oscillatory positive expiratory pressure (oscillatory-PEP) on sputum expectoration and related symptoms in adults with cystic fibrosis (CF). Design Randomised crossover trial. Setting Seven centres. Participants Twenty-two outpatients with CF. Interventions Usual care (HA + HS followed by autogenic drainage) and combined therapy (HA + HS with oscillatory-PEP followed by autogenic drainage]. Each treatment was performed for 5 days. Main outcome measures Sputum expectoration was measured during the nebulisation period (primary outcome), during autogenic drainage and for 24 ho…
Effects of a vestibular physiotherapy protocol on adults with intellectual disability in the prevention of falls: A multi-centre clinical trial
2018
Background Balance alterations are one of the main problems in people with intellectual disabilities (ID), increasing their risk of falls and impacting their life. Aims To describe a vestibular rehabilitation programme (VRP) and evaluate its effects on the ability to maintain balance and risk of suffering a fall. Methods Forty-seven adults with mild to moderate ID were randomly assigned to two groups: a control group (CG, N = 24), which performed a general physical exercise only, and an experimental group (EG, N = 23) which also completed a VRP. The variables, used pre- and post-training and 1 month after the intervention, were as follows: Center of Pressure Displacement, Berg Scale, Timed …
Effects of Dual-Task Group Training on Gait, Cognitive Executive Function, and Quality of Life in People With Parkinson Disease: Results of Randomize…
2020
The aims of this study were to analyze the effects of a dual-task group program, to compare it with the effects of a single-task group program, and to analyze the effects of functional secondary tasks.Single-blind randomized controlled trial.University laboratory and a rehabilitation gym at a health center.Patients (N=40) with a diagnosis of Parkinson disease (mean age, 66.72y; age range, 44-79y) with Hoehn and Yahr stage I to III who were on medication were randomized to either a group with dual-task training or a group with single-task training (only gait).Both interventions involved 20 sessions lasting 1 hour each and conducted twice a week. Dual-task training included walking exercises …
