A double blind controlled trial comparing three treatment modalities for dentin hypersensitivity
2011
Aim: This randomized, double blind, split mouth study was aimed to compare three dentin desensitizing treatment modalities. Methods: Two hundred sixty teeth of 25 patients; each having at least 2 hypersensitive teeth in each quadrant, were included. Teeth were randomized to 4 groups: Group A treated with 2% NaF solution, Group B received GLUMA®; an aqueous solution of Hydroxy-Ethyl-Methacrylate and Glutarldehyde, (HEMA-G), Group C received iontophoresis with distilled water (placebo) and Group D was treated with NaF-iontophoresis. Pain response was evaluated on a visual analogue scale (VAS), by using tactile, air blast and cold-water stimuli at 0-day, 15-day, 1-month and 3-months interval. …
Evaluation of the analgesic efficacies of Dexketoprofen Trometamol and Dexketoprofen Trometamol + Thiocolchicoside combinations in the impacted third…
2019
Background Postoperative pain is one of the most common complications. The aim of this study is to evaluate the analgesic efficacies of dexketoprofen trometamol and two different dosages of dexketoprofen trometamol + thiocolchicoside combination in the impacted third molar tooth operation. Material and Methods This randomized, double-blind study included 75 patients who did not have any disease. Patients were assigned to 3 groups. Group 1 received 25 mg dexketoprofen trometamol + 4 mg thiocholchicoside, Group 2 received 25 mg dexketoprofen trometamol +8 mg thiocholchicoside, and Group 3 received 25 mg dexketoprofen trometamol. In each group, the analgesic medication was administered twice a…
A randomized trial assessing the effectiveness of different concentrations of isotretinoin in the management of lichen planus
2004
The aim of our 10-year study was to test the effectiveness of topical therapy based on 0. 18% isotretinoin, comparing it with that most frequently used, i.e. at 0.05% concentration. Seventy patients with an established diagnosis of oral lichen planus were involved in the study. The patients were randomly divided into two groups, and the drug was administered topically at 0.05% and 0. 18% concentrations. The drug at the higher concentration, according to the same protocol, was administered to the patients who did not benefit from the therapy at the lower concentration. None of the cases of reticular lichen planus showed clinical or histological improvement. In contrast, the atrophic-erosive …
Efficacy and tolerability of lasmiditan, an oral 5-HT1F receptor agonist, for the acute treatment of migraine : a phase 2 randomised, placebo-control…
2012
Lasmiditan (COL-144) is a novel, centrally acting, highly selective 5-HT(1F) receptor agonist without vasoconstrictor activity that seemed effective when given as an intravenous infusion in a proof-of-concept migraine study. We aimed to assess the efficacy and safety of oral lasmiditan for the acute treatment of migraine.In this multicentre, double-blind, parallel-group, dose-ranging study in 43 headache centres in five European countries, patients with migraine with and without aura and who were not using prophylaxis were randomly assigned (1:1:1:1:1) to treat one moderate or severe attack at home with 50 mg, 100 mg, 200 mg, or 400 mg lasmiditan, or placebo. Study drug and placebo were sup…
Methylphenidate, modafinil, and caffeine for cognitive enhancement in chess: A double-blind, randomised controlled trial.
2017
Stimulants and caffeine have been proposed for cognitive enhancement by healthy subjects. This study investigated whether performance in chess - a competitive mind game requiring highly complex cognitive skills - can be enhanced by methylphenidate, modafinil or caffeine. In a phase IV, randomized, double-blind, placebo-controlled trial, 39 male chess players received 2×200mg modafinil, 2×20mg methylphenidate, and 2×200mg caffeine or placebo in a 4×4 crossover design. They played twenty 15-minute games during two sessions against a chess program (Fritz 12; adapted to players' strength) and completed several neuropsychological tests. Marked substance effects were observed since all three subs…
Comparisons of Musculoskeletal Complaints and Data Entry Between a Sitting and a Sit-Stand Workstation Paradigm
2009
Background: Seated working positions are often regarded as a cause for discomfort in the musculoskeletal system. Performing work in different working positions—that is, alternating between sitting and standing (sit-stand workstation paradigm)—could help reduce physical complaints. Objective: The questions were whether performing office work partly in a standing position leads to reduced complaints and whether standing would change the efficiency of data entry office work. Method: We investigated the effect of a sit-stand workstation paradigmd during experimental data entry office work on physical and psychological complaints and data entry efficiency by conducting a randomized controlled t…
Impact of fluoroscopy on oral double-balloon enteroscopy: results of a randomized trial in 156 patients
2010
Background and study aims The routine utility of fluoroscopy during double-balloon enteroscopy (DBE) via the oral route has been not prospectively evaluated. Up to now, there have been no prospective randomized trials to assess whether fluoroscopy improves outcomes. The aim of this study was to assess the value of fluoroscopy during oral DBE. Patients and methods A total of 156 patients (88 men, 56.4 %) of mean (standard deviation [SD]) age 56 (19) years were randomly assigned to undergo oral DBE either with or without fluoroscopy. The majority of the patients had obscure gastrointestinal bleeding (n = 96, 62 %). The primary target criteria for the study were postpyloric insertion depth and…
Efficacy and effectiveness of individual family intervention on social and clinical functioning and family burden in severe schizophrenia: a 2-year r…
2009
BackgroundEmpirical evidence of the efficacy and effectiveness of psychosocial family intervention and of the specificity of its effects on the course of schizophrenia is limited. The aim was to study the efficacy and effectiveness of psychosocial family intervention with regard to clinical and social functioning and family burden after controlling for compliance and several prognostic factors.MethodA 2-year randomized controlled trial with blind assessments. Fifty patients with DSM-IV schizophrenia and persistent positive symptoms and/or previous clinical relapse were allocated to psychosocial family intervention, individual counselling and standard treatment versus individual counselling …
A prospective, double-blind, placebo-controlled trial to establish a safe gluten threshold for patients with celiac disease
2007
BACKGROUND: Treatment of celiac disease (CD) is based on the avoidance of gluten-containing food. However, it is not known whether trace amounts of gluten are harmful to treated patients. OBJECTIVE: The objective was to establish the safety threshold of prolonged exposure to trace amounts of gluten (ie, contaminating gluten). DESIGN: This was a multicenter, double-blind, placebo-controlled, randomized trial in 49 adults with biopsy-proven CD who were being treated with a gluten-free diet (GFD) for > or =2 y. The background daily gluten intake was maintained at < 5 mg. After a baseline evaluation (t0), patients were assigned to ingest daily for 90 d a capsule containing 0, 10, or 50 mg glute…
Randomised study comparing 48 and 96 weeks peginterferon α-2a therapy in genotype D HBeAg-negative chronic hepatitis B
2013
Treatment with peginterferon α-2a (PegIFN) for 48 weeks is the standard of care for selected HBeAg-negative patients chronically infected with hepatitis B virus (HBV), but with limited treatment efficacy. A study was undertaken to investigate whether treatment extension to 96 weeks improves the outcome in this patient population.128 HBeAg-negative patients (120 genotype D) were randomised to weekly 180 μg PegIFN for 48 weeks (group A, n=51), 180 μg PegIFN for 48 weeks followed by 135 μg weekly for an additional 48 weeks (group B, n=52) or 180 μg PegIFN plus lamivudine (100 mg/day) for 48 weeks then 135 μg PegIFN for 48 weeks (group C, n=25). Endpoints were alanine aminotransferase normalisa…
