Objectives: To evaluate electromyogram (EMG) profiles in patients with three related conditions: fibromyalgia, chronic fatigue syndrome, and depression. Methods: We studied 44 healthy volunteers, 22 patients with fibromyalgia, 11 patients with chronic fatigue syndrome, and 10 patients admitted for depression. The trapezius electromyogram was recorded during maximally sustained, bilateral, 90◦ abduction of the shoulders. EMG signal frequency and amplitude were measured throughout the test. Results: In the fibromyalgia group, isometric contraction duration was significantly shorter than in the other two patient groups (P < 0.001) and the EMG frequency and amplitude pattern indicated premature discontinuation of the muscle contraction. Findings in the chronic fatigue patients were similar to those in the healthy controls. The patients with depression had a distinctive EMG profile characterized by excessive initial motor-unit recruitment with a shift in the frequency spectrum. Conclusions: Fibromyalgia was associated with a specific EMG pattern indicating premature discontinuation of the muscle contraction. Therefore, maximal voluntary muscle contraction tests may be of limited value for assessing function in fibromyalgia patients. Chronic fatigue syndrome patients had similar EMG findings to those in the healthy controls. The EMG alterations in the patients with depression were consistent with manifestations of psychomotor retardation. [less ▲]

Musculoskeletal pain is common in the population. Several pathologies like fibromyalgia (FM), chronic fatigue syndrome (CFS) or spasmophilia are associated with functional myalgia. The etiology of FM remains elusive, but the diagnosis is well established. The criteria for the classification are widespread pain combined with tenderness at 11 or more of the 18 specific tender points sites. The prevalence is 2% in the general population. This article reviews recent data on the pathophysiology and treatment of FM. [less ▲]

The aim of this research is to explore the invalidating and facilitating factors related to return to work and/or to maintain work perceived by two groups of patients with chronic diseases: fibromyalgia or chronic back pain. Indeed, the current studies generally examined either return to work or maintaining work; their approach is rarely supported by an integrated view. Our study revealed similarities and differences between the two perspectives but also between the two groups of patients. This will help with the development of future initiatives for returning chronic pain patients to employment. [less ▲]

Objectifs. Évaluer la fonction musculaire d’un groupe de patientes fibromyalgiques et la comparer à celle d’une population féminine de référence. Méthodes. Seize patientes fibromyalgiques et 87 sujets sains féminins sédentaires ou sportifs de loisir ont exécuté un protocole expérimental composé de quatre épreuves. La première évaluait le moment de force isocinétique concentrique maximum des muscles extenseurs et fléchisseurs du genou dominant. Un dynamomètre de Colin autorisait une mesure de la force manuelle isométrique. La résistance musculaire à la fatigue s’appréciait lors d’une épreuve isocinétique de flexion–extension des genoux : le sujet enchaînait 30 contractions concentriques d’intensité maximale à la vitesse angulaire de 180 °/s. La dernière épreuve évaluait l’endurance musculaire statique à l’aide de tests exigeant le maintien d’une position donnée. Résultats. Toutes les variables musculaires apparaissaient réduites chez les sujets fibromyalgiques. Ce déficit, déjà manifeste pour les efforts anaérobiques, s’accentuait lors des efforts en aérobie. Le déficit moyen correspondait à 39 % (p < 0,001) pour la force musculaire, 40 % (p < 0,0001) pour la résistance musculaire à la fatigue et 81 % (p < 0,0001) pour l’endurance musculaire statique. Les perceptions nociceptives au cours de l’effort, évaluées à l’aide d’une échelle visuelle analogique, étaient supérieures chez les patientes fibromyalgiques. Conclusion. L’exploration combinée des trois filières énergétiques confirme l’altération générale de la fonction musculaire du sujet fibromyalgique. Cette étude suggère cependant une perturbation préférentielle des composantes oxydatives. [less ▲]

Fibronectin is a major constituent of the fibroblast extracellular matrix. Fibronectin binds to collagen, mediates fibroblast adhesion to collagen, and is synthesized and secreted into the medium of cultured fibroblasts. Affinity-purified antibodies to fibronectin and collagen were localized using the peroxidase-antiperoxidase method or with ferritin-coupled secondary antibodies. Using human fibroblasts cultured under routine conditions, fibronectin and procollagen I react in a nonperiodic manner with: 1) approximately 10 nm extracellular fibrils, 2) cell membrane, and 3) membrane-associated vesicles. All fibrils react with both antibodies, suggesting some form of codistribution of fibronectin and collagen in these fibrils. Treatment with ascorbate leads to the development of a larger diameter extracellular fibril, approximately 40 nm in diameter. These large diameter fibrils are clearly collagen fibrils as documented by the procollagen antibody reaction. Importantly, fibronectin is bound to or a constituent of these "native" or cellular made collagen fibrils. Fibronectin and procollagen antibodies localized with the peroxidase-antiperoxidase method have a 70 nm axial repeat of reaction product on ascorbate-treated fibroblasts. Localization of antibodies with ferritin-labeled secondary antibodies is less satisfactory, but supports the basic observations made with the unlabeled antibody enzyme method. This observation rules out any potential criticisms. Although it is more difficult to observe with immunoferritin, there is an indication that antibodies to fibronectin react with an axial periodicity on cellular produced collagen fibrils. [less ▲]

By microscopical observation and using an original method of automatic image analysis, we studied on histological sections the rate of lung colony formation after intravenous injection into the mouse of B16 melanoma cells previously cultivated in vitro as pure or mixed spheroids (B16 + 3T3 fibroblasts). The preincubation in vitro of pure spheroids with fibronectin significantly increased the percentages of lung section area occupied by tumors and the relative number of internal lung colonies. This effect of fibronectin was even more obvious when mixed spheroids were injected. [less ▲]

Techniques are now available for culturing well characterized and purified Schwann cells. Therefore, we investigated the role of fibronectin in the adhesion, growth, and migration of cultured rat Schwann cells. Double-immunolabeling shows that, in primary cultures of rat sciatic nerve, Schwann cells (90%) rarely express fibronectin, whereas fibroblasts (10%) exhibit a granular cytoplasmic and fibrillar surface-associated fibronectin. Secondary cultures of purified Schwann cells do not express fibronectin. Exogenous fibronectin has a small effect on promoting the adhesion of Schwann cells to the substrate and does not significantly affect cell morphology, but it produced a surface fibrillar network on fibronectin on the secondary Schwann cells. Tritiated thymidine autoradiography revealed that addition of fibronectin to the medium, even at low concentrations, markedly stimulates Schwann cell proliferation, in both primary and secondary cultures. In addition, when cell migration was measured in a Boyden chamber assay, fibronectin was found to moderately, but clearly, stimulate directed migration or chemotaxis. [less ▲]

The FibroScan is a device allowing a non invasive diagnosis and quantification of liver fibrosis. The procedure is based on transient elastography and allows to record liver stiffness by measuring the velocity of shear wave across liver parenchyma. The elasticity is directly correlated to velocity of the wave. In chronic hepatitis C, there is a good correlation between liver elasticity and stage of fibrosis. The FibroScan has also been studied in other chronic liver diseases, such as hepatitis B, primary biliary cirrhosis, sclerosing cholangitis, auto-immune hepatitis, alcohol, steatosis, hemachromatosis with reproductible results. In a cirrhotic patient, it also allows to assess the severity of cirrhosis and to evaluate the risk of complication. It is a painless procedure, with a good acceptability by the patients. Therefore, the FibroScan can be regularly performed, allowing the follow up of fibrosis evolution over time. [less ▲]

Idiopathic pulmonary fibrosis (IPF) comprises different interstitial lung diseases of unknown origin. They are classified into four groups based on pathologic criteria: UIP, DIP, AIP and NSIP. This classification helps in terms of prognosis and treatment. In addition to history, physical examination and common investigations (chest X ray, pulmonary function testing), a bronchoalveolar lavage (BAL), a high-resolution CT scan and ideally a open-lung biopsy are needed to establish a precise diagnosis. The patients are usually treated by immunosuppressive agents, and mainly by corticoids. However, in UIP, lung transplantation is the only way to improve survival. [less ▲]

Initial experiments towards preparation of hollow ceramic microtubes by dip-coating of fibrous plants with water based alumina gel-casting slurries using hemp and coconut fibres as templates have been done. It has been found that the wettability of fibres and accordingly the stability of the developed ceramic layer on their surface during slurry gelation varied significantly within the different fibre types. Good correlation between the diameters of the template fibres and the resulting channels has been found at the 31 % solids loadings level. Hemp fibres used as bundles have led to formation of multi channel patterns while the coconut fibres-templated process resulted in uniform monochannel materials. The micro tubes have shown good mechanical handling properties. [less ▲]
