    Abstract Cerebrospinal fluid (CSF) filtration has been proposed as a new treatment for Guillain-Barré syndrome (GBS). The theory behind filtering the CSF is that soluble pathogenetic factors or inflammatory mediators including cytokines might be removed from a site where nerve conduction could be impeded or nerve root damage inflicted. There is no pathologic background to recommend continuing with CSF filtration in GBS. Interferon is an immunoregulatory cytokine that reduces relapse frequency in multiple sclerosis and ameliorates experimental autoimmune neuritis, an animal model of GBS. A trial showed that interferon beta-1a would be safe in patients with GBS, but the sample size was too small to detect anything other than a large effect.

    Abstract Guidelines for diagnostic criteria and treatment of chronic inflammatory demyelinating polyneuropathy (CIDP) have been proposed by a joint task force of the European Federation of Neurological Societies and the Peripheral Nerve Society, based on available evidence and expert consensus. These should prove practical for the clinical management of CIDP. Intravenous immunoglobulin followed by corticosteroids should be considered as the initial treatment, however no clear second drug of choice for patients who do not respond to the initial treatment is given. The author reports the long-term therapeutic efficacy of ciclosporin for patients with CIDP who did not show sustained improvement under steroid therapy. Ciclosporin should be tried for patients with intractable CIDP who require repeated intravenous immunoglobulin. An adequate initial dose of ciclosporin is 3 mg/kg/day, with plasma trough concentrations between 100 and 150 ng/ml. If patients respond to ciclosporin, remission can be maintained for 2 years, after which the dose can be slowly reduced over 1 year. Eventual withdrawal should be considered. This review proposes a treatment strategy that includes long-term maintenance therapy for CIDP based on published clinical trials and the author's clinical experience. Current concepts concerning the clinical spectrum of CIDP and diagnostic approaches are also considered.

    Abstract Skeletal muscle regeneration is initiated by the activation of the transcription factor paired box 7 (Pax7), which is expressed in the satellite cells. The nuclear transcription factor T-cell factor 4 (Tcf4) is expressed in the fibroblasts and is involved in muscle tissue repair, while M2-like macrophages play an important role in skeletal muscle regeneration. However, the localization of M2-like macrophages and the expression of Tcf4 over a period of time during skeletal muscle regeneration remain unknown. Therefore, the murine masseter muscle was immunofluorescence investigated for the surface protein CD206 of M2-like macrophages and Tcf4 of fibroblasts during skeletal muscle regeneration to understand the changes in the CD206 and Tcf4 expression over time. We observed that CD206 entered the cytoplasm of some regenerating muscle fibers 5-7 days after the experimental muscle damage, that is, in the early stage of maturation of the regenerating muscle fibers with central nuclei. In addition, Tcf4 was expressed in the nuclei of the fibroblasts around the regenerating muscle fibers and in the central nuclei of the regenerating muscle fibers. Furthermore, the expression of laminin adjacent to Tcf4-positive cells was observed to partially disappear, and the shape of this missing part was observed to be identical to that of the nuclei of Tcf4-positive cells adjacent to the laminin. Clathrin was also expressed in these sites, demonstrating endocytosis. Thus, these results suggest that in the early stage of maturation of the regenerating muscle fibers, M2-like macrophages and Tcf4-positive fibroblasts enter the cytoplasm of the regenerating muscle fibers, thereby regulating the expression of various maturation factors.

    Abstract The coronoid process provides attachment to temporalis and masseter muscles, and thus plays an important role in mastication. Tendons connect muscles and bones, mediating the transmission of functional loads to bones. Thus, tendon-bone entheses govern mechanical stress in bones. The preferential orientation of biological apatite (BAp) crystallites, the main mineral component in bones, is an important index for bone quality and function, and is largely influenced by locally applied stress. In this study, we analyzed BAp orientation, Young's modulus, and bone mineral density (BMD) at different sites in the human coronoid process. No differences in BMD were found among the analyzed sites, but BAp crystal orientation was observed to differ. BAp crystallites showed a uni-directional orientation in the mesiodistal direction at the coronoid process apex, but were oriented in the direction vertical to the occlusal plane at other sites. Young's modulus tended to vary according to the BAp orientation. At the apex, a tendon form with characteristics different from those at other sites, including the presence of a fibrocartilaginous layer that may act as a stretching brake to control stress concentration, was observed. These findings suggest that the functional pressure of the temporalis muscle affects bone quality and strength.

    Abstract Neurofascin-186 (NF186), neuronal cell adhesion molecule (NrCAM), and gliomedin are adhesion molecules playing a central role in the formation of nodes of Ranvier. In Guillain-Barré syndrome (GBS), immune attack toward the nodes may participate in the disabilities. Autoantibodies to NF186 and gliomedin have been detected in a rat model of GBS. Here, we investigated the prevalence of antibodies against nodal adhesion molecules in patients with GBS or chronic inflammatory demyelinating polyneuropathy (CIDP). Sera from 100 GBS patients, 50 CIDP patients, 80 disease controls, and 50 healthy controls were tested for their ability to bind the nodes of Ranvier. To characterize the antigens, we performed cell binding assays against NF186, gliomedin, contactin, and NrCAM. We found that 43% of patients with GBS and 30% of patients with CIDP showed IgG fixation at nodes or paranodes. In eight patients with GBS or CIDP, we identified that IgG antibodies recognized the native extracellular domain of NF186, gliomedin, or contactin. Also, 29 patients showed IgM against nodal adhesion molecules. However, we did not detect IgM fixation at nodes or paranodes. Antibodies to gliomedin or NF186 were mostly detected in demyelinating and axonal GBS, respectively. The adsorption of the antibodies to their soluble antigens abolished IgG deposition at nodes and paranodes in nerves, indicating these were specific to NF186, gliomedin, and contactin. In conclusion, gliomedin, NF186, and contactin are novel target antigens in GBS. At nodes, additional epitopes are also the targets of IgG. These results suggest that antibody attack against nodal antigens participates in the etiology of GBS.

    Abstract Background: The purpose of this study was to reveal the structural properties that need to be considered in dental implant treatment by investigating differences between dentulous and edentulous maxillae in the three-dimensional (3D) microstructure of the incisive canals (ICs) and their surrounding bone.
    Methods: A total of 40 maxillary bones comprising 20 dentulous maxillae and 20 edentulous maxillae were imaged by micro-CT for 3D observation and measurement of the IC and alveolar bone in the anterior region of the IC.
    Results: The Y-morphology canal was most frequently observed at 60% in dentulous maxilla and 55% in edentulous maxilla. There was a significant difference between dentulous and edentulous maxillae in IC diameter and volume, but no significant difference between the two in the major axis of the ICs.
    Conclusions: The anatomic structure surrounding the IC has limited area for implant placement. Therefore, where esthetic and long-term maintenance requirements are taken into account, careful attention is needed when setting the placement position. Also, due to the resorption of bone, edentulous maxillae have a different IC morphology from dentulous maxillae, and therefore, a cautious approach is required.

    Abstract The pterygoid process undergoes ossification of both the cartilage and membrane. However, few studies have attempted to explore the sequential development of the pterygoid process. Using histological examination, we performed morphological observations of the pterygoid process and surrounding tissue. ICR mice at embryonic days 13.5-18.0 and postnatal day 0 were used for morphological observations of the pterygoid process. By embryonic day 14.5, a mesenchymal cell condensation forming the anlage of the future medial pterygoid process differentiated into osteoid-like tissue and cartilage. At embryonic days 15.5-16.5, cartilage cells were clearly evident in the medial pterygoid process. In the medial pterygoid process, a bone collar was evident and calcified bone tissue surrounded the cartilage. At this point, a mesenchymal cell condensation formed the anlage of the pterygoid hamulus. At embryonic days 17.0-18.0, the cartilages were located along the lower and posterior border of the medial pterygoid process. A metachromatically stained matrix first became detectable around cells located in the pterygoid hamulus. On the other hand, at embryonic day 13.5, a metachromatically stained matrix was already evident in the space between the flattened cells in the lateral pterygoid process. At embryonic day 17.0, a hypertrophic cell zone had clearly formed in the diaphysis. On the basis of our present investigation, the lateral pterygoid process can be classified as primary cartilage, whereas the medial pterygoid process can be classified as secondary cartilage. Furthermore, it was found that the pterygoid hamulus is formed latest in the medial pterygoid process.
