Relapsing fever borreliosis is a multisystemic infection characterized primarily by bacteremia but can extend to the CNS. The incidence of CNS disease manifestations in humans depends on the infecting relapsing fever Borrelia species. In the murine model of Borrelia hermsii infection we found high incidence of distinct signs of CNS disease that ranged from a flaccid tail to complete paralysis of hind limbs. Infiltration of large number of T cells into the spinal cord of B. hermsii-infected mice and the upregulation of MHC class II and CD80 on infiltrating macrophages and on microglial cells suggested a role for T cell and Ag-presenting cell interactions in this pathogenesis. Indeed, B. hermsii infection did not induce CNS disease manifestations in T cell-deficient mice (TCR-ß × d-/-), although it resulted in bacteremia comparable to wild-type (Wt) level. Moreover, the infiltration of immune cells into the spinal cord of TCR-ß × d-/- mice was reduced and the resident microglial cells were not activated. Histopathological analysis of lumbar sections of the spinal cord confirmed severe inflammation in Wt but not in TCR-ß × d-/- mice. Induction of CNS disease was dependent on the B. hermsii strain as well as on the ability of the host to control bacteremia. Mice that are impaired in controlling B. hermsii, such as CD14-/- mice, exhibited more severe CNS disease than Wt mice. This study demonstrates that distinct neurologic disease manifestations develop during relapsing fever and that T cells play a critical role in the induction of neuropathogenesis.

Introduction: Chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature (CANDLE) is an auto inflammatory syndrome caused by an autosomal recessive gene mutation. This very rare syndrome has been reported in only 14 patients worldwide. A number of clinical signs have been reported including joint contractures, muscle atrophy, microcytic anaemia, and panniculitis-induced childhood lipodystrophy. Further symptoms include recurrent fevers, purpuric skin lesions, periorbital erythema and failure to thrive. This is the first reported case of periodontal manifestations associated with CANDLE syndrome. 
Case Presentation: An 11 year old boy was referred to Cork University Dental School and Hospital with evidence of severe periodontal destruction. The patient’s medical condition was managed in Great Ormond Street Children’s Hospital, London. The patient’s dental management included initial treatment to remove teeth of hopeless prognosis followed by prosthodontic rehabilitation using removable partial dentures. This was followed by further non-surgical periodontal treatment and maintenance. In the long term, the potential definitive restorative options, including dental implants, will be evaluated in discussion with the patient’s medical team.
Conclusion: Periodontitis as a manifestation of systemic disease is one of seven categories of periodontitis as defined by the American Academy of Periodontology 1999 classification system. A number of systemic diseases have been associated with advanced periodontal destruction including Diabetes Mellitus, Leukaemia and Papillon-Lefevre Syndrome. In the case described, treatment necessitated a multidisciplinary approach with input from medical and dental specialities for a young patient with severe periodontal destruction associated with CANDLE syndrome.

Cette étude s'inscrit dans le contexte du mouvement professionnalisant de la formation initiale à l'enseignement. Dans ce contexte, la personne enseignante associée y joue un rôle important. Toutefois, il est possible d'observer l'absence de consensus sur les façons de remplir ce rôle. À la lumière de la recension des écrits, cette étude stipule que le fait de stimuler le raisonnement pédagogique des stagiaires constitue une visée d'accompagnement cohérente avec les travaux s'insérant dans ce mouvement. De plus, cette étude soutient que l'accompagnement réflexif apparaît comme un accompagnement susceptible de stimuler le raisonnement pédagogique. Cette recherche analyse les conceptions et les pratiques de personnes enseignantes associées au regard du raisonnement pédagogique et de l'accompagnement réflexif. De plus, elle analyse les manifestations du raisonnement pédagogique et des autres activités réflexives des stagiaires. Pour ce faire, la perspective de l'interactionnisme symbolique a été privilégiée tout en s'insérant dans le paradigme interprétatif. Les résultats permettent de constater que les conceptions des personnes enseignantes associées, au regard du raisonnement pédagogique, s'approchent davantage d'une définition de la réflexion. Les résultats soulèvent aussi que les rencontres sont caractérisées par une utilisation prépondérante de questions ainsi que par une tendance générale plutôt non réflexive. De plus, les résultats permettent de constater que les activités réflexives des stagiaires sont caractérisées par un déploiement prépondérant de la confirmation ainsi que par des manifestations de raisonnement pédagogique. Certaines hypothèses sont émises pour interpréter ces résultats dont, entre autres, l'influence probable des caractéristiques de la recherche, de certaines stagiaires à l'étude, de certaines personnes enseignantes associées, etc. Les résultats permettent de mieux cerner la contribution d'un accompagnement réflexif à l'émergence et au développement du raisonnement pédagogique des stagiaires. Toutefois, des recherches supplémentaires doivent être mises sur pied pour tenter de pousser plus loin les hypothèses émises.

Extraintestinal manifestations (EIM) in inflammatory bowel disease (IBD) are frequent and may occur before or after IBD diagnosis. EIM may impact the quality of life for patients with IBD significantly requiring specific treatment depending on the affected organ(s). They most frequently affect joints, skin, or eyes, but can also less frequently involve other organs such as liver, lungs, or pancreas. Certain EIM, such as peripheral arthritis, oral aphthous ulcers, episcleritis, or erythema nodosum, are frequently associated with active intestinal inflammation and usually improve by treatment of the intestinal activity. Other EIM, such as uveitis or ankylosing spondylitis, usually occur independent of intestinal inflammatory activity. For other not so rare EIM, such as pyoderma gangrenosum and primary sclerosing cholangitis, the association with the activity of the underlying IBD is unclear. Successful therapy of EIM is essential for improving quality of life of patients with IBD. Besides other options, tumor necrosis factor antibody therapy is an important therapy for EIM in patients with IBD.
