High-Frequency Transcranial Magnetic Stimulation on Motor Cortex of Patients Affected by Migraine With Aura: A Way to Restore Normal Cortical Excitab…
2009
We showed reduced motor intracortical inhibition (ICI) and paradoxical increase of intracortical facilitation (ICF) to 1 Hz repetitive transcranial magnetic stimulation (rTMS) in patients affected by migraine with aura (MA). In conditions of enhanced excitability due to a reduced inhibition, high-frequency rTMS was found to potentiate intracortical inhibition. Here we explored the conditioning effects of high-frequency priming stimulation of motor cortex with the aim of normalizing excitability reverting paradoxical facilitation by 1 Hz rTMS in MA. Nine patients with MA and nine healthy controls underwent a paired-pulse TMS paradigm to evaluate motor intracortical excitability (ICI and ICF…
Recognition memory and prefrontal cortex: Dissociating recollection and familiarity processes using rTMS
2008
Recognition memory can be supported by both the assessment of the familiarity of an item and by the recollection of the context in which an item was encountered. The neural substrates of these memory processes are controversial. To address these issues we applied repetitive transcranial magnetic stimulation (rTMS) over the right and left dorsolateral prefrontal cortex (DLPFC) of healthy subjects performing a remember/know task. rTMS disrupted familiarity judgments when applied before encoding of stimuli over both right and left DLPFC. rTMS disrupted recollection when applied before encoding of stimuli over the right DLPFC. These findings suggest that the DLPFC plays a critical role in recog…
Effectiveness of cognitive-behavioral group therapy for patients with hypochondriasis (health anxiety)
2014
Cognitive behavioral therapy (CBT) has been shown to be highly effective in the treatment of health anxiety. However, little is known about the effectiveness of group CBT in the treatment of health anxiety. The current study is the largest study that has investigated the effectiveness of combined individual and group CBT for patients with the diagnosis of hypochondriasis (N=80). Therapy outcomes were evaluated by several questionnaires. Patients showed a large improvement on these primary outcome measures both post-treatment (Cohen's d=0.82-1.08) and at a 12-month follow-up (Cohen's d=1.09-1.41). Measures of general psychopathology and somatic symptoms showed significant improvements, with …
Vertical distraction osteogenesis of a free vascularized fibula flap in a reconstructed hemimandible for mandibular reconstruction and optimization o…
2009
Free vascularized fibular flap is considered the treatment of choice in mandibular reconstruction for extensive bone defects (over 6 centimeters) resulting from trauma, infections or tumor resections. But, when the reconstruction involves a dentate mandible, the fibula has the limit as it does not offer sufficient bone height to restore the alveolar arch up to the occlusal plane. Therefore, the deficiency in bone height makes implant placement impractical. We report a case of vertical distraction osteogenesis of a free vascularized fibula flap used to reconstruct a hemimandible after resection of an odontogenic myxoma, for optimization of the implant prosthetic rehabilitation. The distracti…
Thigh-length versus below-knee compression elastic stockings for prevention of the postthrombotic syndrome in patients with proximal-venous thrombosi…
2012
Abstract Although below-knee compression elastic stockings (CES) are effective for the prevention of the postthrombotic syndrome (PTS), a substantial number of patients with deep venous thrombosis still develop PTS. In the present open-label, randomized clinical trial, we compared thigh-length with below-knee CES for the prevention of PTS. A total of 267 patients with the first episode of proximal deep venous thrombosis were randomized to wear either thigh-length or below-knee CES for 2 years. After 3, 6, 12, 18, 24, and 36 months, they were assessed for PTS manifestations according to the Villalta scale. PTS developed in 44 (32.6%) of the 135 patients randomized to thigh-length CES and in …
Paired pulse TMS over the right posterior parietal cortex modulates visuospatial perception
2006
Abstract Objective We previously observed a relative contralateral neglect by right parietal single-pulse TMS given 150 ms after visual stimulus presentation. Here we investigated the effects of parietal paired TMS in normal subjects performing a visuospatial task. Methods Thirteen right-handed healthy subjects underwent a line-length judgement task during single-pulse and paired (1, 3, 5, 10 ms ISIs) TMS, delivered on the right parietal cortex 150 ms after visual stimulus. Results Single pulse TMS over the right parietal cortex induced a significant rightward bias compared to the baseline condition. At 1 and 3 ms ISIs, paired-pulse TMS did not show any effect in comparison with single puls…
Gender-related differences in psychometric properties of WHO Disability Assessment Schedule 2.0
2019
Objective of this study was to investigate the gender-related differential item function of 12-item WHODAS 2.0 amongst patients with chronic musculoskeletal pain. This was a cross-sectional survey study among 1,988 patients at a university Physical and Rehabilitation Medicine outpatient clinic. To assess DIF, WHODAS 2.0 items were dichotomized as `none’ rated by respondents as `0’ versus `any limitation’ rated as `1,2,3 or 4’. The item response theory analysis was used to define discrimination and difficulty parameters of a questionnaire. The probit logistic regression was used to test uniformity of DIF between gender groups. The results of DIF analysis were presented and evaluated graphica…
Do elite endurance athletes report their training accurately?
2013
Purpose:The purpose of this study was to validate the accuracy of self-reported (SR) training duration and intensity distribution in elite endurance athletes.Methods:Twenty-four elite cross-country skiers (25 ± 4 y, 67.9 ± 9.88 kg, 75.9 ± 6.50 mL · min−1 · kg−1) SR all training sessions during an ~14-d altitude-training camp. Heart rate (HR) and some blood lactate measurements were collected during 466 training sessions. SR training was compared with recorded training duration from HR monitors, and SR intensity distribution was compared with expert analysis (EA) of all session data.Results:SR training was nearly perfectly correlated with recorded training duration (r = .99), but SR training…
Study of Obsessive Compulsive Beliefs: Relationship with Eating Disorders
2011
Background: The relationship between Eating Disorders (ED) and Obsessive Compulsive Disorder (OCD) has been extensively studied in the last few years. However, little effort has been devoted to studying the link between these disorders with regard to their distorted beliefs. Aims: The first objective of the study was to analyze the differences in OCD-related beliefs among ED subtypes and the general population, controlling for age, Body Mass Index, and obsessionality. The second objective was to explore which OCD beliefs explain ED symptomatology. Method: Seventy-nine ED patients without OCD comorbidity, divided into diagnostic subtypes, and 50 community participants completed the Obsessive…
Neural correlates of antinociception in borderline personality disorder.
2006
Context A characteristic feature of borderline personality disorder (BPD) is self-injurious behavior in conjunction with stress-induced reduction of pain perception. Reduced pain sensitivity has been experimentally confirmed in patients with BPD, but the neural correlates of antinociceptive mechanisms in BPD are unknown. We predicted that heat stimuli in patients with BPD would activate brain areas concerned with cognitive and emotional evaluation of pain. Objective To assess the psychophysical properties and neural correlates of altered pain processing in patients with BPD. Design Case-control study. Setting A university hospital. Participants Twelve women with BPD and self-injurious behav…
