Pain Neurophysiology Education and Therapeutic Exercise for Patients With Chronic Low Back Pain: A Single-Blind Randomized Controlled Trial.
2018
Abstract: Objective To assess the effect of a pain neurophysiology education (PNE) program plus therapeutic exercise (TE) for patients with chronic low back pain (CLBP). Design Single-blind randomized controlled trial. Setting Private clinic and university. Participants Patients with CLBP for ≥6 months (N=56). Interventions Participants were randomized to receive either a TE program consisting of motor control, stretching, and aerobic exercises (n=28) or the same TE program in addition to a PNE program (n=28), conducted in two 30- to 50-minute sessions in groups of 4 to 6 participants. Main Outcomes Measures The primary outcome was pain intensity rated on the numerical pain rating scale whi…
Anterior limbic alpha-like activity: a low resolution electromagnetic tomography study with lorazepam challenge
2005
Summary Objective To verify findings of an independently regulated anterior limbic alpha band source. Methods In a randomised cross-over study, the spontaneous EEG was recorded in nine healthy subjects after i.v. lorazepam or placebo. Intracerebral current densities within classical frequency bands were estimated with low resolution electromagnetic tomography [LORETA] and compared between groups with t -statistical parametric mapping [SPM{ t }]. A region-of-interest [ROI] based method was used to compare frontal and occipital alpha band activity changes. Results Irrespective of treatment group, local maxima of alpha band power were localised both in the occipital lobe, Brodman area [BA] 18,…
An approach to single trial analysis of event-related potentials based on signal detection theory.
1996
Abstract The aim of the present paper was to introduce a single trial analysis to event-related potential measurement in order to illuminate the mechanisms behind an impaired P300 amplitude occurring under certain experimental conditions. For this purpose we applied tools from linear system theory and signal detection theory to single trials in an oddball paradigm in order to estimate the amplitude of the positive deflection around the P300 latency following target and nontarget stimuli. According to the density functions of these amplitude distributions we operationally defined ‘P300 absent in target’ (P300 amplitude smaller than an individual threshold under target conditions) as well as …
Implant treatment planning regarding augmentation procedures: panoramic radiographs vs. cone beam computed tomography images.
2015
Objectives To evaluate the impact of cone beam computed tomography (CBCT) imaging on treatment planning regarding augmentation procedures for implant placement. Material and methods Panoramic radiographs and CBCT images of 40 patients requesting single-tooth implants in 59 sites were retrospectively analyzed by six specialists in implantology, and treatment planning was performed. Therapeutic recommendations were compared with the surgical protocol performed initially. Results Bone height estimation from panoramic radiographs yielded to higher measures and greater variability compared to CBCT. The suggested treatment plan for lateral and vertical augmentation procedures based on CBCT or pan…
Visceral infiltration of intrahepatic cholangiocarcinoma is most prognostic after curative resection - Retrospective cohort study of 102 consecutive …
2018
Intrahepatic cholangiocarcinoma (ICC) is a rare malignancy, and therefore large unicenter series on the surgical outcome are rare in the literature, and prognostic factors for overall survival in the literature vary widely.All patients who underwent surgery for ICC were prospectively recorded. The type of resection, operative details, histological results, morbidity, mortality, overall and recurrence-free survivals as well as prognostic factors were assessed. Prognostic factors were examined by univariate and multivariate analyses. P-values0.05 were considered significant.Between January 2008 and December 2015, 102 patients underwent a resection with curative intent and were included in thi…
Marginal soft tissue stability around conical abutments inserted with the one abutment-one time protocol after 5 years of prosthetic loading
2018
BACKGROUND Soft tissue stability is crucial to obtain and maintain optimal esthetic results. PURPOSE This study aimed to investigate, over 5 years, the soft tissue response using a conical abutment together with the "one-abutment one-time" (OA-OT) protocol in the restoration of implants inserted in the anterior esthetic area. MATERIAL AND METHODS From January 2011 to January 2012, all consecutive patients requiring an implant n the maxillary area between canines were enrolled. After submerged healing and osseointegration, a definitive abutment with a provisional crown was inserted. After 1 month, the definitive crown was delivered (Tdef). Analog impressions were taken before tooth extractio…
Pharmacokinetic analysis of the interaction between dicoumarol and tolbutamide in man
1976
The effect of repeated administration of tolbutamide on the elimination and anticoagulant action of a single oral dose of dicoumarol 600 mg was studied in four healthy male subjects using a crossover design. In all subjects the plasma concentration of dicoumarol in the postabsorptive phase was lower during concomitant tolbutamide treatment. However, the subjects differed with respect to the elimination kinetics of dicoumarol and the effect of tolbutamide on some of the measured pharmacokinetic paramaters. In two subjects dicoumarol was eliminated by apparent first-order kinetics. Tolbutamide led to a pronounced increase in the elimination rate and a shift in the plasma concentration-respons…
Prospective, cross-over, single-center trial comparing oral double-balloon enteroscopy and oral spiral enteroscopy in patients with suspected small-b…
2011
BACKGROUND AND STUDY AIMS: Spiral enteroscopy is a new, promising rapid enteroscopy technique. A prospective cross-over study was carried out to compare this new method with the established technique of double-balloon enteroscopy (DBE). PATIENTS AND METHODS: From an initial group of 18 patients with suspected mid-gastrointestinal bleeding due to vascular malformations but no previous history of small-bowel or colonic surgery, 10 patients (mean age 69 years) completed the study. Patients underwent both enteroscopy techniques with an oral approach, in a randomized sequence. The deepest point reached during advancement in the first enteroscopy was marked with India ink. The primary end point o…
Double-balloon enteroscopy (push-and-pull enteroscopy) of the small bowel: feasibility and diagnostic and therapeutic yield in patients with suspecte…
2005
Background Double-balloon enteroscopy (push-and-pull enteroscopy) is a new method that allows complete visualization, biopsy, and treatment in the small bowel. This study evaluated the feasibility and the diagnostic and the therapeutic yield of double-balloon enteroscopy (push-and-pull enteroscopy) in comparison with current imaging methods. Methods Between March 2003 and November 2004, 248 consecutive double-balloon enteroscopies (push-and-pull enteroscopies) were performed in a prospective study in 137 patients with suspected small-bowel disease (60 women, 77 men; mean age 56.6 ± 17.8 years), most with chronic GI bleeding (66%). The examinations were carried out after negative evaluations…
Sensory-specific satiety for a food is unaffected by the ad libitum intake of other foods during a meal. Is SSS subject to dishabituation?
2012
Sensory-specific satiety (SSS) is defined as a decrease in the pleasantness of a specific food that has just been eaten to satiation, while other non-eaten foods remain pleasant. The objectives of this study were the following: (1) to investigate whether SSS for a food is affected by the ad libitum intake of other foods presented sequentially during a meal, (2) to compare the development of SSS when foods are presented simultaneously or sequentially during a meal, and (3) to examine whether SSS is modified when foods are presented in an unusual order within a meal. Twelve participants participated in three tasting sessions. In session A, SSS for protein-, fat- and carbohydrate-rich sandwich…
