Guidance parentale et respect de l'intimité. Deuil et érotisme chez les mineurs

Des parents semblent ignorer la limite entre ce que l'on est en droit de montrer et ce que l'on doit traiter avec pudeur. Une sorte d'ambiguïté les amène à être négligents et par là à tolérer des comportements ou des propos grivois de leurs enfants ou à en rire. Les thérapeutes sont invités à entreprendre un travail pédagogique de guidance parentale quand les frontières de l'intime sont floues et quand la confusion touche les jeunes devenant vulnérables et symptomatiques. Les auteurs exposent un cas d'anorexie chez une adolescente, dont la souffrance se trouve masquée par une série de comportements désinhibés. La surexcitation qui en découle peut apparaître comme une solution défensive pour lutter contre la dépression liée à l'expérience de séparation et de deuil. Pour favoriser la construction de représentations des territoires de l'intime plus respectueuses de la vulnérabilité des adolescents, les auteurs ont aussi proposé la sculpture familiale.Parental guidance and respect of intimacy. Young people's mourning and erotism. - Parents seem to be unaware of the borderline between what one may show and what one should handle with reserve. A kind of ambiguity drive them to be careless. As a result, they put up with suggestive behaviour or language from their children and even laugh at it. The therapists are invited to undertake an educational work of parental guidance when the boderlines of the intimate are hazy and when the confusion is affecting young people who become vulnerable and symptomatic. The authors present an anorexia case of a teenager whose distress is concealed by a series of uninhibited behaviours. The ensuing overexcitement could seem to be a defensive solution to fight against the depression related to parting and mourning experience. To encourage the building of representations of the territories of the intimate which would be more respectful of the teenagers vulnerability, the authors also suggest the technique of family sculpture.

Pin guidance of reconstruction plate contour: an expanded role of external fixation

This article presents a modification of intraoperative external fixation for mandibular reconstruction with free tissue flaps. This technique is indicated when preregistration of the reconstruction plate is not possible due to transmandibular tumor extension. Once standard external fixation has been carried out and prior to segmental mandibulectomy, additional pins are fixed to the connecting rod that delineate the mandibular contour in three-dimensional (3D) space. Following mandibulectomy, these pins allow accurate contouring of the reconstruction plate and improved restoration of mandibular contour, projection, and dental occlusion. A step-by-step description of the technique using models and intraoperative photos is presented. This method of mandibular reconstruction is a simple and time-effective alternative to intraoperative computer navigation and 3D modeling in select cases of oral carcinoma where tumor infiltration of the outer mandibular cortex precludes prebending of the reconstruction plates.

The fusion protein of wild-type canine distemper virus is a major determinant of persistent infection.

The wild-type A75/17 canine distemper virus (CDV) strain induces a persistent infection in the central nervous system but infects cell lines very inefficiently. In contrast, the genetically more distant Onderstepoort CDV vaccine strain (OP-CDV) induces extensive syncytia formation. Here, we investigated the roles of wild-type fusion (F(WT)) and attachment (H(WT)) proteins in Vero cells expressing, or not, the canine SLAM receptor by transfection experiments and by studying recombinants viruses expressing different combinations of wild-type and OP-CDV glycoproteins. We show that low fusogenicity is not due to a defect of the envelope proteins to reach the cell surface and that H(WT) determines persistent infection in a receptor-dependent manner, emphasizing the role of SLAM as a potent enhancer of fusogenicity. However, importantly, F(WT) reduced cell-to-cell fusion independently of the cell surface receptor, thus demonstrating that the fusion protein of the neurovirulent A75/17-CDV strain plays a key role in determining persistent infection.

Adaptation of canine distemper virus to canine footpad keratinocytes modifies polymerase activity and fusogenicity through amino acid substitutions in the P/V/C and H proteins.

The wild-type canine distemper virus (CDV) strain A75/17 induces a non-cytocidal infection in cultures of canine footpad keratinocytes (CFKs) but produces very little progeny virus. After only three passages in CFKs, the virus produced 100-fold more progeny and induced a limited cytopathic effect. Sequence analysis of the CFK-adapted virus revealed only three amino acid differences, of which one was located in each the P/V/C, M and H proteins. In order to assess which amino acid changes were responsible for the increase of infectious virus production and altered phenotype of infection, we generated a series of recombinant viruses. Their analysis showed that the altered P/V/C proteins were responsible for the higher levels of virus progeny formation and that the amino acid change in the cytoplasmic tail of the H protein was the major determinant of cytopathogenicity.

Partial protection and intrathecal invasion of CD8(+) T cells in acute canine distemper virus infection.

Initial non-inflammatory demyelination in canine distemper virus infection (CDV) develops against a background of severe immunosuppression and is therefore, thought to be virus-induced. However, recently we found a marked invasion of T cells throughout the central nervous system (CNS) in dogs with acute distemper despite drastic damage to the immune system. In the present study, this apparent paradox was further investigated by immunophenotyping of lymphocytes, following experimental CDV challenge in vaccinated and non-vaccinated dogs. In contrast to CDV infected, unprotected dogs, vaccinated dogs did not become immunosuppressed and exhibited a strong antiviral immune response following challenge with virulent CDV. In unprotected dogs rapid and drastic lymphopenia was initially due to depletion of T cells. In peripheral blood, CD4(+) T cells were more sensitive and depleted earlier and for a longer time than CD8(+) cells which recovered soon. In the cerebrospinal fluid (CSF) we could observe an increase in the T cell to B cell and CD8(+) to CD4(+) ratios. Thus, partial protection of the CD8(+) cell population could explain why part of the immune function in acute distemper is preserved. As found earlier, T cells invaded the CNS parenchyma in these dogs but also in the protected challenged dogs, which did not develop any CNS disease at all. Since markers of T cell activation were upregulated in both groups of animals, this phenomenon could in part be related to non-specific penetration of activated T cells through the blood brain barrier. However, in diseased animals much larger numbers of T cells were found in the CNS than in the protected dogs, suggesting that massive invasion of T cells in the brain requires CDV expression in the CNS.

Rapid improvement of canine cognitive dysfunction with immunotherapy designed for Alzheimer's disease

Immunotherapy against amyloid-β(Aβ) may improve rodent cognitive function by reducing amyloid neuropathology and is being validated in clinical trials with positive preliminary results. However, for a complete understanding of the direct and long-term immunization responses in the aged patient, and also to avoid significant side effects, several key aspects remain to be clarified. Thus, to investigate brain Aβ clearance and Th2 responses in the elderly, and the reverse inflammatory events not found in the immunized rodent, better Alzheimer"s disease (AD) models are required. In the aged familiar canine with a Cognitive Dysfunction Syndrome (CDS) we describe the rapid effectiveness and the full safety profile of a new active vaccine candidate for human AD prevention and treatment. In these aged animals, besidesa weak immune system, the antibody response activated a coordinated central and peripheral Aβ clearance, that rapidly improved their cognitive function in absence of any side effects. Our results also confirm the interest to use familiar dogs to develop innovative and reliable therapies for AD.

Role of mutations in the phosphoprotein on RNA polymerase activity of canine distemper virus following cell culture adaptation

Abstract: The canine distemper virus A75/17 wild-type strain, which is unable to replicate in cell lines, was adapted to growth in Vero cells. Sequence comparison between the A75/17 and the Vero cell-adapted A75/17-V virus revealed 7 amino acid differences between the 2 viruses. Three of these were located in the matrix protein, three in the phosphoprotein also changing the V protein but not the C protein and one in the large protein. The phosphoprotein and the large protein constituted the viral RNA polymerase whose activity was studied by transfection experiments using a reverse genetic system with a plasmid encoding a minireplicon and expression plasmids encoding the nucleocapsid protein and the viral RNA polymerase subunits. Surprinsingly, the enzyme of A75/17 CDV was significantly more active in cell lines compared to the polymerase of A75/17-V CDV. The decrease in overall enzyme activity was found to be due to both decreased replication and transcription activity. This polymerase attenuation was confirmed in CHO cells infection stably expressing the dog SLAM receptor mainly found in dog's lymphoid organs and allowing both virus strains to enter these cells at the same efficiency. A75/17-V CDV replicated more slowly in CHODogSLAM cells than A75/17 CDV and syncytium formation was significantly decreased compared to A75/17 infected CHODogSLAM cells.. Cell culture adaptation lead to an attenuated virus strain both in vitro and in vivo with decreased polymerase activity and syncytium forming capability showing an important role of the polymerase in determining the phenoytpe of the virus. In addition, this reduced phenotype of A75/17-V CDV was shown to be due to the P mutations in the P protein only, showing an important function of the polycistronic P gene in the adaptation process. The role of the matrix protein was found not to have any effect on polymerase activity, however its participation in the adaptation process still needs to be elucidated. The accessory proteins V and C were shown to act on polymerase activity, but their functions in virus pathogenicity and in inhibiting the interferon system have not been studied in this thesis. The V proteins have an activating effect on the polymerase of both the A75/17 and the A75/17-V CDV strains. Although the C protein amino acid sequence was not changed during adaptation of wild-type canine distemper virus in Vero cells, the C protein was demonstrated to have opposite effects on polymerase activity of both virus strains suggesting a different interaction of the C protein with the proteins forming the polymerase complex, which could modulate polymeras activity. These effects were demonstrated by transfection experiments and studying recombinant viruses not expressing the C protein. Thus, the abrogation of the C protein decrease the activity of the wild-type polymerase. In contrast, the polymerase activity of the Vero cell- adapted virus is enhanced in the absence of the C protein and this has also been demonstrated with a recombinant virus, which grew faster in the first 48 hours of infection. Future studies will focus on the generation of recombinant wild-type viruses, which should be very helpful in understanding the molecular mechanisms underlying the adaptation process and the loss of pathogenicity.

Practical guidance and considerations for transitioning patients from oxcarbazepine or carbamazepine to eslicarbazepine acetate--Expert opinion.

There is currently a lack of guidance on methodology and special considerations for transitioning patients from oxcarbazepine (OXC) or carbamazepine (CBZ) to eslicarbazepine acetate (ESL), if deemed clinically necessary. An advisory panel of epilepsy experts was convened to share their experience on the use of adjunctive ESL in clinical practice and to provide practical recommendations to help address this gap. When changing over from OXC to ESL, an OXC:ESL dose ratio of 1:1 should be employed to calculate the ESL target dose, and the changeover can take place overnight. No changes to comedication are required. Since CBZ has a different mechanism of action to ESL and is a stronger inducer of cytochrome P450 (CYP) enzymes, the transitioning of patients from CBZ to ESL requires careful consideration on a patient-by-patient basis. In general, a CBZ:ESL dose ratio of 1:1.3 should be employed to calculate the ESL target dose, and patients should be transitioned over a minimum period of 1-2weeks. Special considerations include adjustment of titration schedule and target dose in elderly patients and those with hepatic or renal impairment and potential adjustment of comedications metabolized by CYP enzymes. In summary, due to structural distinctions between ESL, OXC, and CBZ, which affect mechanism of action and tolerability, there are clinical situations in which it may be appropriate to consider transitioning patients from OXC or CBZ to ESL. Changing patients over from OXC to ESL is generally more straightforward than transitioning patients from CBZ to ESL, which requires careful consideration.
