Side-effects of extracorporeal shock wave therapy (ESWT) in the treatment of tennis elbow
2002
Apart from a few observational reports, there are no studies on the side-effects of extracorporeal shock wave therapy (ESWT) in the treatment of insertion tendopathies. Within the framework of a randomised, placebo-controlled, single-blind, multicentre study to test the effectiveness of ESWT in the case of lateral epicondylitis (LE), side-effects were systematically recorded. A total of 272 patients from 15 centres was allocated at random to active ESWT (3 x 2000 pulses, energy flux density ED(+) 0.04 to 0.22 mJ/mm(2) under local anaesthesia) or placebo ESWT. In all, 399 ESWT and 402 placebo treatments were analysed. More side-effects were documented in the ESWT group (OR = 4.3, CI = [2.9; …
Exercise Diminishes Plasma Neurofilament Light Chain and Reroutes the Kynurenine Pathway in Multiple Sclerosis
2020
ObjectiveTo examine acute (single-bout) and training effects of high-intensity interval training (HIIT) vs standard exercise therapy (moderate continuous training [MCT]) on plasma neurofilament light chain (pNfL) and kynurenine (KYN) pathway of tryptophan degradation metabolites in persons with multiple sclerosis (pwMS).MethodsSixty-nine pwMS (Expanded Disability Status Scale score 3.0–6.0) were randomly assigned to a HIIT or an MCT group. Changes in pNfL and KYN pathway metabolites measured in blood plasma were assessed before, after, and 3 hours after the first training session as well as after the 3-week training intervention.ResultsAcute exercise reduced pNfL and increased the KYN pathw…
A comparative study of naproxen gel and flufenamic acid gel in the treatment of soft tissue injuries.
1990
One hundred patients were enrolled in a single-blind, randomized, parallel group study to compare naproxen gel (10%) with flufenamic acid gel (3%) for the treatment of soft tissue injuries. Demographic variables, the distribution of diagnoses (tendinitis, bursitis/synovitis, synovitis, periarthritis, epicondylitis) and initial severity of the complaint were similar between the two groups. The gels were applied 2 to 6 times per day, as required, and conventional clinical indices were evaluated at Day 1 (on entry to the study), Day 3 and Day 7. Global assessments of efficacy were made by both physicians and patients at the end of the study. By Day 7 both treatments had produced a highly signi…
Posaconazole vs. Fluconazole or Itraconazole Prophylaxis in Patients with Neutropenia
2007
Patients with neutropenia resulting from chemotherapy for acute myelogenous leukemia or the myelodysplastic syndrome are at high risk for difficult-to-treat and often fatal invasive fungal infections.In this randomized, multicenter study involving evaluators who were unaware of treatment assignments, we compared the efficacy and safety of posaconazole with those of fluconazole or itraconazole as prophylaxis for patients with prolonged neutropenia. Patients received prophylaxis with each cycle of chemotherapy until recovery from neutropenia and complete remission, until occurrence of an invasive fungal infection, or for up to 12 weeks, whichever came first. We compared the incidence of prove…
Vulnerability to psychotogenic effects of ketamine is associated with elevated D2/3-receptor availability.
2012
Previous positron emission tomography (PET) studies employing competition paradigms have shown either no change or substantial declines in striatal ( 11 C)-raclopride binding after challenge with psychotogenic doses of the N-methyl-D-aspartate antagonist ketamine. We sought to probe the relationship between the severity of ketamine-induced psychotic symptoms and altered dopamine D2/3 receptor availability throughout brain using the high affinity ligand ( 18 F)-fallypride (FP). PET recordings were obtained in a group of 10 healthy, young male volunteers, in a placebo condition, and in the course of an infusion with ketamine at a psychotomimetic dose. Administration of the Positive and Negati…
No short-term effects of digital mobile radio telephone on the awake human electroencephalogram
1997
A recent study reported the results of an exploratory study of alterations of the quantitative sleep profile due to the effects of a digital mobile radio telephone. Rapid eye movement (REM) was suppressed, and the spectral power density in the 8–13 Hz frequency range during REM sleep was altered. The aim of the present study was to illuminate the influence of digital mobile radio telephone on the awake electroencephalogram (EEG) of healthy subjects. For this purpose, we investigated 34 male subjects in a single-blind cross-over design experiment by measuring spontaneous EEGs under closed-eyes condition from scalp positions C3 and C4 and comparing the effects of an active (0.05 mW/cm2) and a…
Prognostic effect of carbohydrate antigen 125-guided therapy in patients recently discharged for acute heart failure (CHANCE-HF). Study design.
2014
Abstract Introduction and objectives Morbidity and mortality after admission for acute heart failure remain prohibitively high. In that setting, plasma levels of antigen carbohydrate 125 have shown to correlate with the severity of fluid overload and the risk of mortality and readmission. Preliminary data suggests a potential role of antigen carbohydrate 125 to guide therapy. The objective of this study is to evaluate the prognostic effect of an antigen carbohydrate 125-guided management strategy vs standard therapy in patients recently discharged for acute heart failure. Methods This is a multicenter, randomized, single-blind, efficacy trial study of patients recently discharged from acute…
A new delivery system of clobetasol-17-propionate (lipid-loaded microspheres 0.025%) compared with a conventional formulation (lipophilic ointment in…
2004
Summary Background Topical application of clobetasol-17-propionate has been diffusely reported as an efficacious therapy in atrophic/erosive oral lichen planus (OLP), without exposing the patient to systemic side-effects. However, prolonged contact and respective topical effects on the oral mucosa should be avoided. Objectives The aim of the present study was to evaluate efficacy and compliance of new lipid microspheres loaded with 0·025% of clobetasol propionate (formulation A) compared with a commonly used formulation (a sort of dispersion of a lipophilic ointment in a hydrophilic phase) with the same amount of drug (formulation B) in the topical treatment of OLP. Patients and methods …
A Comparison of Five Maintenance Therapies for Reflux Esophagitis
1995
Patients with reflux esophagitis have a high rate of relapse within one year after therapy is discontinued.We enrolled 175 adults with endoscopy-confirmed reflux esophagitis in a prospective study comparing five maintenance therapies. All the patients were initially treated with omeprazole (40 mg orally once a day) for four to eight weeks, and healing was confirmed by endoscopy. Participants were then stratified according to their initial grade of esophagitis and randomly assigned to 12 months of treatment with one of the following: cisapride (10 mg three times a day), ranitidine (150 mg three times a day), omeprazole (20 mg per day), ranitidine plus cisapride (10 mg three times a day), or …
Bone Marrow Concentrate and Bovine Bone Mineral for Sinus Floor Augmentation
2011
Purpose: The purpose of this work was to evaluate the potential of substituting autogenous bone (AB) by bone marrow aspirate concentrate (BMAC). Both AB and BMAC were tested in combination with a bovine bone mineral (BBM) for their ability of new bone formation (NBF) in a multicentric, randomized, controlled, clinical and histological noninferiority trial.Materials and Methods: Forty-five severely atrophied maxillary sinus from 26 patients were evaluated in a partial cross-over design. As test arm, 34 sinus of 25 patients were augmented with BBM and BMAC containing mesenchymal stem cells. Eleven control sinus from 11 patients were augmented with a mixture of 70% BBM and 30% AB.
