Noradrenergic cardiac denervation is associated with gait velocity in Parkinson disease: a dual ligand PET study.

PURPOSE: Preliminary data suggest that gait abnormalities in Parkinson disease (PD) may be associated with sympathetic cardiac denervation. No kinematic gait studies were performed to confirm this observation. We aimed to correlate spatiotemporal kinematic gait parameters with cardiac sympathetic denervation as determined by cardiac [11C]HED PET in PD. METHODS: Retrospective database analysis of 27 PD patients with cardiac sympathetic denervation. All patients underwent spatiotemporal kinematic gait assessment (medication 'off' state), cardiac [11C]HED and dopaminergic brain [11C]DTBZ PET scans. We employed a hierarchical regression approach to examine associations between the extent of cardiac denervation, dopaminergic nigrostriatal neurodegeneration, and three gait parameters - velocity, step length and cadence. RESULTS: More extensive cardiac denervation was associated with slower velocity (estimate: -1.034, 95% CI [-1.65, -0.42], p = 0.002), shorter step length (estimate: -0.818, 95% CI [-1.43, -0.21], p = 0.011) and lower cadence (estimate: -0.752, 95% CI [-1.28, -0.23], p = 0.007) explaining alone 30% (Adjusted-R²: 0.297), 20% (Adjusted-R²: 0.202) and 23% (Adjusted-R²: 0.227) of the variability, respecivetly. These associations remained independent of striatal dopaminergic impairment and confounding factors such as age, Hoehn and Yahr (HY) stages, peripheral neuropathy, cognition, and autonomic symptoms. In contrast, striatal dopaminergic denervation was significantly associated with step length (estimate: 0.883, 95% CI [0.29, 1.48], p = 0.005), explaining about 24% of the variability but was dependent of HY stage. CONCLUSIONS: More severe cardiac noradrenergic denervation was associated with lower gait velocity, independent of striatal dopaminergic denervation and HY stage, impacting both step length and cadence. These results suggest independent contributions of the peripheral autonomic system degeneration on gait dynsfunction in PD.

Cardiac sympathetic denervation and anxiety in Parkinson disease.

BACKGROUND: Anxiety in Parkinson disease (PD) negatively impacts quality of life. While research predominantly focuses on central nervous system changes, some evidence suggests a connection between peripheral autonomic dysfunctions and PD-related anxiety. The role of the peripheral autonomic nervous system in this context may be overlooked. OBJECTIVES: This study explores the link between anxiety symptoms and cardiac sympathetic denervation in PD using 11C-meta-hydroxyephedrine ([11C]HED) PET cardiac imaging. METHODS: We studied 34 non-demented PD subjects, assessing anxiety levels through the Spielberg Anxiety State-Trait test trait section (STAI-T). Patients underwent comprehensive assessments along with [11C]HED cardiac and [11C]DTBZ brain PET. To identify subdimensions of STAI-T, we employed principal components analysis (PCA). We examined associations between the anxiety subdimensions and two measures of cardiac sympathetic denervation from [11C]HED PET. We utilized correlation and linear regression models for these analyses. RESULTS: PCA revealed two STAI-T results components: anxiety-depressive and pure anxiety subcomponents. Only pure anxiety significantly correlated with measures of cardiac sympathetic denervation (rhos -0.40, p = 0.018; 0.35, p = 0.043). Regression models confirmed a significant association, with cardiac sympathetic denervation explaining ∼20 % of pure anxiety variance, independent of sex, dopaminergic impairment, and anxiolytic treatments. DISCUSSION: This study provides preliminary evidence of peripheral autonomic nervous system abnormalities contributing to PD-related anxiety, suggesting dysregulation in peripheral autonomic functions influencing anxiety perception.

Investigating the aspect of asymmetry in brain-first versus body-first Parkinson's disease.

Parkinson's disease (PD) is characterized by a progressive loss of dopaminergic neurons in the substantia nigra. Recent literature has proposed two subgroups of PD. The "body-first subtype" is associated with a prodrome of isolated REM-sleep Behavior Disorder (iRBD) and a relatively symmetric brain degeneration. The "brain-first subtype" is suggested to have a more asymmetric degeneration and a prodromal stage without RBD. This study aims to investigate the proposed difference in symmetry of the degeneration pattern in the presumed body and brain-first PD subtypes. We analyzed 123I-FP-CIT (DAT SPECT) and 18F-FDG PET brain imaging in three groups of patients (iRBD, n = 20, de novo PD with prodromal RBD, n = 22, and de novo PD without RBD, n = 16) and evaluated dopaminergic and glucose metabolic symmetry. The RBD status of all patients was confirmed with video-polysomnography. The PD groups did not differ from each other with regard to the relative or absolute asymmetry of DAT uptake in the putamen (p = 1.0 and p = 0.4, respectively). The patient groups also did not differ from each other with regard to the symmetry of expression of the PD-related metabolic pattern (PDRP) in each hemisphere. The PD groups had no difference in symmetry considering mean FDG uptake in left and right regions of interest and generally had the same degree of symmetry as controls, while the iRBD patients had nine regions with abnormal left-right differences (p < 0.001). Our findings do not support the asymmetry aspect of the "body-first" versus "brain-first" hypothesis.

Speckle tracking echocardiography in plasma cell disorders: The role of advanced imaging in the early diagnosis of AL systemic cardiac amyloidosis.

INTRODUCTION: Amyloid light-chain amyloidosis is a rare condition characterized by the abnormal production of immunoglobulin light chain that misshape and form amyloid fibrils. Over time, these amyloid deposits can accumulate slowly, causing dysfunction in organs and tissues. Early identification is crucial to ensure optimal treatment. We aim to identify a better marker of cardiac amyloidosis, using advanced echocardiography, to improve diagnosis and the timing of available treatments. MATERIALS AND METHODS: 108 consecutive hematological patients (32, 30% female and 76, 70% male) with a plasma cell disorder referred to our Cardiological center underwent ECG, first and second-level echocardiography (Speckle Tracking) and complete biochemical profile. The best predictors of ALCA (AUC ≥ 0.8) were included in a further analysis stratified by AL score. RESULTS: At ROC analysis, the best bio-humoral predictors for the diagnosis of ALCA were Nt-pro-BNP (AUC: 0.97; p < 0.01) and Hs-Tn (AUC: 0.87; p < 0.01). Regarding echocardiography, the best diagnostic predictors were left atrial stiffness (LAS) (AUC: 0.83; p < 0.01) for the left atrium; free wall thickness for the right ventricle (AUC: 0.82; <0.01); left ventricular global longitudinal strain (LVGLS) (AUC: 0.92; p < 0.01) and LVMi (AUC 0.80; p < 0.001) for the left ventricle; and AL-score (AUC 0.83 p < 0.01). In patients with AL-SCORE < 1, LAS (AUC 0.86 vs AUC 0.79), LVGLS (AUC 0.92 vs AUC 0.86) and LV mass (AUC 0.91 vs AUC 0.72) had better diagnostic accuracy than patients with higher AL-score (AL SCORE ≥ 1). CONCLUSION: Multi-parametric imaging approach with LVGLS and LAS may be helpful for detecting early cardiac involvement in AL amyloidosis.

Management of patients with severe asthma: results from a survey among allergists and clinical immunologists of the Central Italy Inter-Regional Section of SIAAIC.

BACKGROUND: Asthma, and severe asthma in particular, is often managed within a specialized field with allergists and clinical immunologists playing a leading role. In this respect, the National Scientific Society SIAAIC (Società Italiana di Allergologia, Asma ed Immunologia Clinica), structured in Regional and Inter-Regional sections, interviewed a large number of specialists involved in the management of this respiratory disease. METHODS: A survey entitled "Management of patients with asthma and severe asthma" based on 17 questions was conducted through the SIAAIC newsletter in 2019 thanks to the collaboration between GlaxoSmithKline S.p.A. and the Inter-Regional Section of SIAAIC of Central Italy. RESULTS: Fifty-nine allergists and clinical immunologists participated to the survey, and 40 of them completed the entire questionnaire. Almost all of the specialists (88%) reported that asthma control was achieved in above 50% of their patients, even if only one third (32%) actually used validated clinical tools such as asthma control test (ACT). Poor adherence to inhaled therapy was recognized as the main cause of asthma control failure by 60% of respondents, and 2-5 min on average is dedicated to the patient inhaler technique training by two-thirds of the experts (65%). Maintenance and as-needed therapy (SMART/MART) is considered an appropriate approach in only a minority of the patients (25%) by one half of the respondents (52%). A high number of exacerbations despite the maximum inhalation therapy were recognized as highly suspicious of severe asthma. Patients eligible for biological therapies are 3-5% of the patients, and almost all the responders (95%) agreed that patients affected by severe asthma need to be managed in specialized centers with dedicated settings. Biological drugs are generally prescribed after 3-6 months from the initial access to the center, and once started, the follow-up is initially programmed monthly, and then every 3-6 months after the first year of treatment (96% of responders). After phenotyping and severity assessment, comorbidities (urticaria, chronic rhinosinusitis with or without nasal polyps, vasculitis, etc.) are the drivers of choice among the different biological drugs. In the management of severe asthma, general practitioners (GPs) should play a central role in selecting patients and referring them to specialized centers while Scientific Societies should train GPs to appropriately recognize difficult asthma and promote public disease awareness campaigns. CONCLUSIONS: This survey which collects the point of view of allergists and clinical immunologists from Central Italy highlights that asthma control is still not measured with validated instruments. There is a general consensus that severe asthma should be managed only in dedicated centers and to this aim it is essential to encourage patient selection from a primary care setting and develop disease awareness campaigns for patients.

Right cardiac involvement in lung diseases: a multimodality approach from diagnosis to prognostication.

Lung diseases are amongst the main healthcare issues in the general population, having a high burden of morbidity and mortality. The cardiovascular system has a key role in patients affected by respiratory disorders. More specifically, the right ventricle (RV) enables the impaired lung function to be overcome in an initial stage of disease process, reducing the severity of dyspnoea. In addition, two of the main causes of death in this setting are RV failure and sudden cardiac death (SCD). Echocardiography is regarded as a useful and easily available tool in assessing RV function. Several noninvasive echocardiographic parameters of elevated pulmonary pressures and RV function have been proposed. The combination of different parameters and imaging methods is paramount and researches regarding RV impairment using these indices has been specifically addressed in relation to the chronic obstructive and restrictive lung disease in order to guide the clinicians in the management of these patients. Cardiac involvement in lung diseases is often observed, and RV changes are reported also in early stages of pulmonary diseases. The role of right ventricle in chronic respiratory disease patients has to be evaluated in detail to describe the response to therapy and the degree of disease progression through multimodality and advanced imaging techniques. The aim of this review is to describe the different pathophysiological mechanisms of cardiac impairment in primary lung disease (such as chronic obstructive pulmonary disease (COPD), idiopathic pulmonary fibrosis (IPF) and sarcoidosis) and to summarize the role of cardiac multimodality imaging in the diagnosis and the prognosis of these diseases.

In-vivo signatures of neurodegeneration in isolated rapid eye movement sleep behaviour disorder.

BACKGROUND AND PURPOSE: Isolated rapid eye movement sleep behaviour disorder (iRBD) is a parasomnia, recently recognized as a risk factor for progression to Parkinson's disease, dementia with Lewy body and multiple system atrophy. Biomarker studies in iRBD are relevant due to lack of evidence in this condition. The identification of biomarkers able to predict progression to synucleinopathy diseases is critical for iRBD. Fluorodeoxyglucose-positron emission tomography (FDG-PET) imaging might provide information about ongoing neurodegenerative processes. In the present study, we tested for presence of brain hypometabolism patterns as biomarkers of neurodegeneration in single iRBD individuals. METHODS: We recruited 37 subjects with polysomnography-confirmed iRBD, with neuropsychological assessment and available FDG-PET scan. Images were analysed with a validated statistical parametric mapping procedure, providing individual hypometabolism maps. RESULTS: According to the neuropsychological evaluation, 22 subjects with iRBD had normal cognition and 15 subjects showed impairments, particularly in visuoperceptive/visuospatial and memory domains. One-fifth of the cases were impaired on the Qualitative Scoring of Pentagon Test. In 32 iRBD cases, FDG-PET statistical parametric maps revealed significant cerebral hypometabolism, namely in the occipital lobes (n = 5), occipital and cerebellar regions (n = 13), occipitoparietal regions (n = 13) and a selective cerebellar hypometabolism (n = 1). Five cases had normal FDG-PET scans. CONCLUSIONS: These imaging findings indicate that brain neurodegenerative processes are present and already detectable in iRBD. The different hypometabolism patterns in the single individuals may reflect specific early pathophysiological events due to the underlying synucleinopathy, with a specific neural vulnerability for the occipital cortex that might pre-date a risk of progression towards dementia with Lewy body.

Allergic reactions after vaccination: translating guidelines into clinical practice.

Summary: Vaccination represents one of the most powerful medical interventions on global health. Despite being safe, sustainable, and effective against infectious and in some cases also non-infectious diseases, it's nowadays facing general opinion's hesitancy because of a false perceived risk of adverse events. Adverse reactions to vaccines are relatively rare, instead, and those recognizing a hypersensitivity mechanism are even rarer. The purpose of this review is to offer a practical approach to adverse events after vaccination, focusing on immune-mediated reactions with particular regard to their recognition, diagnosis and management. According to clinical features, we propose an algorythm for allergologic work-up, which helps in confirming hypersensitivity to vaccine, nonetheless ensuring access to vaccination. Finally, a screening questionnaire is included, providing criteria for immunisation in specialized care settings.

Hypersensitivity reactions to non-vitamin K oral anticoagulants - a review of literature and diagnostic work-up proposal.

Summary: Non-vitamin K antagonist oral anticoagulants (NOACs) are increasingly being used in hospital and outpatient settings as safe alternatives to warfarin. Hypersensitivity reactions have been described for NOACs and can be classified according to Gell and Coombs. We reviewed case reports of possible drug hypersensitivity reactions, noticing a predominance of delayed reactions (both mild and severe) and the absence of cross-reactions to warfarin and low molecu-lar weight heparins. International experience on diagnostic tests is lacking. The vast majority of authors refer to probability scores and rely on biopsy to classify vasculitis and rule out differential diagnoses. We propose to adapt available tests to confirm the patient's reactivity to new anticoagulants. Among in vivo tests, patch testing revealed promising in delayed reactions.

Long-Term Functional Outcome after Internal Delorme's Procedure for Obstructed Defecation Syndrome, and the Role of Postoperative Rehabilitation.

PURPOSE: To evaluate long-term functional outcomes of Internal Delorme's Procedure (IDP) in patients refractory to conservative treatment for Obstructed Defecation Syndrome (ODS), and to compare those who received postoperative rehabilitation with those who did not. MATERIALS AND METHODS: All patients with ODS refractory to nonoperative therapy were identified across three regional pelvic floor referral hospitals, and IDP was performed. Postoperatively selected patients received biofeedback therapy. Functional outcomes were established using the Cleveland Clinic Constipation (CCC) score and obstructed defecation score (OD score) preoperatively at 12 months and at the last available follow-up. Patient satisfaction was assessed with a visual analogue score. RESULTS: From October 2006 to September 2013, IDP was performed in 170 patients: 77 received postoperative biofeedback and 93 did not. Mean follow-up was 6.3 years (range 1-8 years). CCC and OD scores improved significantly in both groups after 12 months and at the last follow-up (p > 0.05). When comparing two groups while there was no significant difference between CCC and OD scores at 12 months, score was significantly better in the group that received rehabilitation at the last follow-up (p = 0.001). Patient satisfaction was higher in the rehabilitation group (67%) compared with those without rehabilitation (55%). Clinical recurrence was recorded in nine patients who did not have postoperative rehabilitation. CONCLUSIONS: It has been demonstrated that IDP is associated with good long-term functional outcomes. Patients receiving rehabilitation had a better long-term follow-up, a higher overall satisfaction, and lower recurrence rate when compared with the patients who did not receive postoperative rehabilitation.

Dynamics and phylogenetic relationships of HIV-1 transmitted drug resistance according to subtype in Italy over the years 2000-14.

Background: Transmitted drug-resistance (TDR) remains a critical aspect for the management of HIV-1-infected individuals. Thus, studying the dynamics of TDR is crucial to optimize HIV care. Methods: In total, 4323 HIV-1 protease/reverse-transcriptase sequences from drug-naive individuals diagnosed in north and central Italy between 2000 and 2014 were analysed. TDR was evaluated over time. Maximum-likelihood and Bayesian phylogenetic trees with bootstrap and Bayesian-probability supports defined transmission clusters. Results: Most individuals were males (80.2%) and Italian (72.1%), with a median (IQR) age of 37 (30-45) years. MSM accounted for 42.2% of cases, followed by heterosexuals (36.4%). Non-B subtype infections accounted for 30.8% of the overall population and increased over time (<2005-14: 19.5%-38.5%, P < 0.0001), particularly among Italians (<2005-14: 6.5%-28.8%, P < 0.0001). TDR prevalence was 8.8% and increased over time in non-B subtypes (<2005-14: 2%-7.1%, P = 0.018). Overall, 467 transmission clusters (involving 1207 individuals; 27.9%) were identified. The prevalence of individuals grouping in transmission clusters increased over time in both B (<2005-14: 12.9%-33.5%, P = 0.001) and non-B subtypes (<2005-14: 18.4%-41.9%, P = 0.006). TDR transmission clusters were 13.3% within the overall cluster observed and dramatically increased in recent years (<2005-14: 14.3%-35.5%, P = 0.005). This recent increase was mainly due to non-B subtype-infected individuals, who were also more frequently involved in large transmission clusters than those infected with a B subtype [median number of individuals in transmission clusters: 7 (IQR 6-19) versus 4 (3-4), P = 0.047]. Conclusions: The epidemiology of HIV transmission changed greatly over time; the increasing number of transmission clusters (sometimes with drug resistance) shows that detection and proper treatment of the multi-transmitters is a major target for controlling HIV spread.

Interações entre antiparasitários e alimentos / Interactions between antiparasitic drugs and food

O uso, por vezes indiscriminado, de antiparasitários pode levar a consequências importantes na saúde do indivíduo, principalmente relacionadas a alterações no sistema gastrointestinal. As interações entre fármacos e nutrientes podem ocorrer quando um alimento ou nutriente altera a resposta esperada de um medicamento ou quando este interfere sobre o estado nutricional do indivíduo. Essa alteração da eficácia pode resultar em falha no tratamento ou até mesmo na toxicidade do fármaco. A fim de conhecer, identificar e prevenir interações indesejáveis entre antiparasitários e alimentos, o presente artigo de revisão aborda os principais fármacos e alimentos ou nutrientes envolvidos, bem como as consequências que tais interações podem acarretar ao indivíduo. O estado nutricional é de suma importância nas infecções parasitárias, pois é o determinante entre uma maior carga de parasitos ou a resistência total contra a infecção. De forma geral, indivíduos parasitados são inapetentes e emagrecidos, o que em crianças pode comprometer o desenvolvimento físico e intelectual. Portanto, o conhecimento e uma correta orientação médica, farmacêutica e nutricional levam a um tratamento bem sucedido...

The often indiscriminate use of antiparasitic drugs can lead to serious consequences for the health of the individual, mainly related to alterations in the gastrointestinal system. Interactions between drugs and nutrients may occur when a food or nutrient changes the expected response of a drug or when a medicine interferes with the individual's nutritional status. These changes may result in treatment failure or even toxicity of the drug. As an aid to the detection, identification and prevention of undesirable interactions between foods and antiparasite drugs, in this review we discuss the major drugs and foods or nutrients involved and the consequences that these interactions can have for the individual. Nutritional status is important in parasitic infections, as it is a factor determining the parasite load level or the total resistance against infection. Generally, individuals infected by parasites have a poor appetiteand are emaciated, which in children can damage physical and intellectual development. Therefore, knowledge of the parasite and proper medical, pharmaceutical and nutritional guidance lead to a more successful treatment...

Hypnotizability and haptics: visual recognition of unimanually explored 'nonmeaningful' objects.

The cognitive trait of hypnotizability modulates sensorimotor integration and mental imagery. In particular, earlier results show that visual recognition of 'nonmeaningful', unfamiliar objects bimanually explored is faster and more accurate in subjects with high (Highs) than with low hypnotizability (Lows). The present study was aimed at investigating whether Highs exhibit a similar advantage after unimanual exploration. Recognition frequency (RF) and Recognition time (RT) of correct recognitions of the explored objects were recorded. The results showed the absence of any hypnotizability-related difference in recognition frequencies. In addition, RF of the right and left hand was comparable in Highs as in Lows, while slight differences were found in RT. We suggest that hemispheric co-operation played a key role in the better performance of Highs in the bimanual task previously studied. In the unimanual exploration, the task's characteristics (favoring the left hand), hypnotizability-related cerebral asymmetry (favoring the right hand in Highs) and the possible preferential verbal style of recognition in Lows (favoring the right hand in this group) antagonize each other and prevent the occurrence of major differences between the performance of Highs and Lows.

[Management of biohazard in health care settings]. / Gestione del rischio biologico in ospedale.

The management of biohazard in health care settings entails multidisciplinarity, valuing the interactions among stakeholders (General Manager, Medical Director, health care workers, prevention and protection units, infection control panels, occupational physicians), with the aim of protecting health and safety of workers, third parties and the health care service. The management issue was tackled within SIMLII guidelines on biohazards, as well as by the SIMLII Section on Preventive Medicine for Health Care Workers, followed by editorial initiatives. This contribution focuses on afield example on the management of data stemming from accidents involving biohazards, highlighting the need of information technology enabling management of enormous amount of health data. This work underlines the primacy of individual risk assessment and management, while combining information on working techniques and procedures with modern health surveillance, on the basis of accredited literature and good medical, organizational and technical practices.

Can imagery become reality?

Previous studies showed that highly hypnotizable persons imagining a specific sensory context behave according to the corresponding real stimulation and perceive their behaviour as involuntary. The aim of the study was to confirm the hypothesis of a translation of sensory imagery into real perception and, thus, of a true involuntary response. We studied the imagery-induced modulation of the vestibulospinal (VS) reflex earlier component in highly (Highs) and low hypnotizable subjects (Lows), as it is not affected by voluntary control, its amplitude depends on the stimulus intensity, and the plane of body sway depends on the position of the head with respect to the trunk. Results showed that the effects of the "obstructive" imagery of anaesthesia are different from those elicited by the "constructive" imagery of head rotation. Indeed, both Highs and Lows having their face forward and reporting high vividness of imagery experienced anaesthesia and reduced their VS reflex amplitude in the frontal plane, while only Highs changed the plane of body sway according to the imagined head rotation that is from the frontal to the sagittal one. These effects cannot be voluntary and should be attributed to translation of sensory imagery into the corresponding real perception.

Modulation of the postural effects of cognitive load by hypnotizability.

Aim of the experiment was to study whether cognitive load affects postural control more in low (Lows) than in highly hypnotizable (Highs) subjects due to the latter's greater attentional abilities. Standing Highs and Lows underwent an experimental session (closed eyes) consisting of a basal condition and of mental computation in an easy (stable support) and a difficult (unstable support) postural condition. Variability [standard deviation (SD)] and complexity [sample entropy (SampEn)] of the movement of the centre of pressure (CoP), its mean velocity (Velocity), the area swept by the CoP (Area) and the ratio between the CoP trajectory length and area [length for surface (LFS)] were measured. Few hypnotizability-related differences were detected (reduction in the Highs' SD and increases in the Lows' LFS in the difficult postural condition). Thus, the hypnotizability-related postural differences observed in previous studies during sensory alteration could not be accounted mainly by attentional abilities.

One-year efficacy of a 3-week intensive multidisciplinary non-pharmacological treatment program for fibromyalgia patients.

OBJECTIVE: The aim of the present study was to investigate the long-term efficacy of a 3-week intensive residential multidisciplinary non-pharmacological treatment program (including individually prescribed and monitored aerobic exercise and cognitive behavioural therapy) on fibromyalgia symptoms and aerobic fitness. METHODS: Twenty-five women with fibromyalgia participated in six experimental sessions (pre-admission, immediately before and immediately after the treatment, and to 2, 5 and 12 months afterwards) in which they underwent clinical, psychophysical and psychological examinations: pain intensity (VAS), pain area (percentage of total body surface), deep pressure pain threshold at 18 tender point sites measured with a pressure algometer, an incremental step test with blood lactate determination and calculation of the individual intensity of exercise corresponding to 2 mM of lactate concentration (W2, index of aerobic fitness). Depression and coping were evaluated with the Center for Epidemiologic Studies Depression Scale (CES-D) and Brief Pain Coping Inventory (BPCI), respectively. RESULTS: Pain intensity, pain area and number of positive tender points were significantly reduced up to 12 months, while deep pressure pain threshold and W2 increased. CES-D score decreased until two months. Among the 18 items of the BCPI, only item 3 ("physical exercise/stretching") changed significantly, increasing until 12 months. CONCLUSION: In fibromyalgia patients, whose symptoms before treatment were constant, a 3-week intensive residential multidisciplinary treatment program showed one-year efficacy in improving pain and aerobic fitness. The acquisition of physical exercise as a coping strategy for chronic pain acceptance could explain the long-term effects of our brief treatment.

Paradoxical experience of hypnotic analgesia in low hypnotizable fibromyalgic patients.

The study investigated the differences in pain perception in highly (Highs) and low (Lows) hypnotizable patients with chronic benign pain undergoing hypnotic suggestions of analgesia. Self reports of pain intensity were collected in different groups of fibromyalgic patients: (1) Highs and Lows during pre-hypnosis, neutral hypnosis, suggestions for analgesia, posthypnotic conditions; (2) Lows during suggestions for analgesia administered after a mental stress instead of neutral hypnosis; (3) healthy Lows receiving nociceptive stimulation during hypnotic relaxation and suggestions of analgesia. The results showed that Highs and Lows differed in their response to suggestions, but significant analgesia was reported also by Lows. These individuals did not report any difference in pain perception between the sessions including mental stress and hypnotic relaxation. No change in pain perception was observed in healthy Lows during nociceptive stimulation associated with relaxation and suggestions for analgesia. In conclusion, the presence of chronic pain seems to be responsible for the paradoxical response of non hypnotizable patients to hypnotic suggestions.
