Ce travail de thèse tente de favoriser une meilleure connaissance de l'étude de la sensibilité à l'anxiété chez l'enfant et de sa pertinence, ainsi que de permettre une compréhension plus précise des facteurs impliqués dans le développement d'une sensibilité à l'anxiété chez l'enfant. De manière plus spécifique, il poursuit trois objectifs précis. (1) Après une description détaillée de la littérature sur la pertinence d'étudier un concept tel que la sensibilité à l'anxiété, il parait important d'être en mesure de posséder une échelle valide permettant de l'investiguer. Le questionnaire de sensibilité à l'anxiété chez l'enfant, intitulé Children Anxiety Sensitivity Index (CASI) de Silverman, Fleisig, Rabian, & Peterson (1991), n’a pas encore fait l'objet d'une validation dans une population belge. Une analyse de la structure factorielle, ainsi qu'une exploration des qualités psychométriques de la version française de la CASI est le premier objectif de cette étude. (2) Le deuxième objectif concerne l'impact de rôle de genre et de l'intelligence émotionnelle dans le développement d'une sensibilité à l'anxiété chez l'enfant. Différents auteurs mettent en avant la pertinence de prendre en compte le rôle de genre, plutôt que le sexe biologique, dans la .prévalence des troubles anxieux. Ceci est davantage documenté dans une population adulte, et n'a jamais été investigué dans la sensibilité à l'anxiété. De plus, les compétences émotionnelles ont montré leur facteur protecteur dans la vie de l'enfant, tant au niveau relationnel, que psychologique et physique. Ce travail investigue si cet effet protecteur est également présent dans la sensibilité à l'anxiété. (3) Enfin, le troisième objectif approfondit la question de l'influence des parents dans le développement d'une sensibilité à l'anxiété chez l'enfant. En effet, la littérature met en évidence l'implication parentale dans la présence des peurs des sensations anxieuses chez l'enfant. En conséquence, la sensibilité à l'anxiété des parents ainsi que les expériences d'apprentissages catastrophiques au sein du milieu familial sont examinées. De plus, l'influence de deux modérateurs est investigué: plus spécifiquement, l'impact d'un facteur de vulnérabilité et de protection, respectivement le niveau de féminité (du parent et de l'enfant) et l'intelligence émotionnelle de l'enfant dans le lien entre les facteurs parentaux et le développement d'une sensibilité à l'anxiété chez l'enfant.

Objectifs: Déterminer le devenir à long terme de 55 patients avec une maladie de Cushing, suivis en moyenne 26+/-3.8 mois. Conclusions: Les adénomes corticotropes sont le plus souvent des microadénomes latéraux, envahissant les structures adjacentes dans 30% des cas. Le traitement de première intention est la microchirurgie par voie transphenoidale, permettant une guérison dans 76% des cas. Malgré un taux bas d'échecs immédiats, (11%) les récidives à moyen et long terme (13%) ne sont pas négligeables. Ceci est probablement lié à la fréquence de l'invasion locale, mise en évidence par les données neuroradiologiques et chirurgicales. Sur les 14 paramètres analysées, trois critères peuvent et être considérés comme prédictifs du devenir des patients opérés d'une maladie de Cushing: les signes d'invasion tumorale locale sur IRM ou visualisés par le neurochirurgien et les taux postopératoires immédiats de cortisol. Cependant ces paramètres son t indicatifs et ne dispensent pas du suivi annuel des patients, nécessaire afin de dépister les éventuelles récidives pouvant bénéficier d'une radiothérapie complémentaire focalisée ou non.

BACKGROUND: The in vivo interdependence between the phenotypic characteristics of dermal cells and the strain imposed on the tissue has not been studied thoroughly in humans. In particular the mechanical force modulation of Factor XIII a expression in dermal dendrocytes (DD) remains unknown. MATERIALS AND METHODS: The present study compares the numerical density of Factor XIII a-positive DD and the in vivo shear wave velocity in the skin. The investigation was performed in 20 men of normal weight and 20 obese men before and after entering a slimming process. RESULTS: Excess cutaneous fat places the skin under increased intrinsic tension. The resonance running time measurement (RRTM) and the DD density were significantly reduced in overweight individuals. After a short-term but intense slimming process, the same individuals showed a trend to normalization of these two parameters without, however, reaching significance. Pooling all data yielded a significant logarithmic correlation between RRTM values and densities in Factor XIII a-positive DD. CONCLUSION: Factor XIII a expression in human DD may be partially regulated by the intrinsic resting tensions in the skin. [less ▲]

The Ehlers-Danlos syndrome (EDS) represents a heterogeneous group of connective tissue disorders recognized by distinct clinical, microscopic, and biochemical aspects. In particular, some histologic and ultrastructural clues have been reported in the literature. We present a novel immunohistochemical aid to the diagnosis of the most frequent type of EDS. Factor XIIIa-positive dendrocytes are almost absent in the reticular dermis and markedly reduced in number and size in the adventitial dermis. By contrast, the densities of vimentin-positive cells and CD34-positive cells were unremarkable. The biologic significance of this finding is unknown. However, at least a subset of dermal dendrocytes interacts with fibroblasts. This mechanism could be affected in the classic form of EDS. [less ▲]

Factor XIIIa-positive dendrocytes present at the periphery and inside epithelial neoplasms are an heterogeneous group of cells. They are subsets of mesenchymal cells, cancer-associated macrophages and antigen-presenting cells. Factor XIIIa, other tissue transglutaminases, alpha 2-macroglobulin and tumour necrosis factor-alpha represent a complex network of mediators influencing tumour progression in the skin. In the present study we searched for the presence of dendrocytes and alpha 2-macroglobulin deposits inside and in the vicinity of cutaneous carcinomas (90 basal cell carcinomas and 46 squamous cell carcinomas) and malignant melanomas (69 primary and 28 metastatic tumours). We also studied the proliferation of the same neoplasms by Ki-67 immunohistochemistry. Dendrocytes were numerous, abutting on and infiltrating most basal cell carcinomas and thin malignant melanomas. In contrast, they were present in only low numbers or even absent in thick primary malignant melanomas and in their metastases. They appeared unmodified around squamous cell carcinomas compared with the surrounding skin. Extracellular deposits of alpha 2-macroglobulin were often found in locations where dermal dendrocytes were numerous. No correlation was found between the Ki-67 indices of carcinomas and the density of peritumoral dendrocytes. In contrast, negative relationships were found between the Ki-67 indices and the number of dendrocytes present inside basal cell carcinomas and thin malignant melanomas. This study has yielded circumstantial evidence to link the density of factor XIIIa-positive dendritic cells and a low proliferative rate of neoplastic cells in basal cell carcinomas and malignant melanomas.

BACKGROUND: Drug-induced toxic epidermal necrolysis (TEN) is a rare life-threatening disease characterized by the extensive destruction of the epidermis contrasting with the discreteness of lymphoid cell infiltration. The precise pathomechanism of the disease remains unclear. METHODS: Skin specimens and peripheral and thoracic lymph nodes (LNs) were collected from 2 TEN patients. They were examined by conventional histology and immunohistochemistry using antibodies directed to factor XIIIa (dermal dendrocytes), CD1a (Langerhans cells), CD15 (granulocytes), CD20 (B lymphocytes), CD45RO (activated T lymphocytes), CD68 (macrophages) and the proliferation marker Ki-67. LNs from patients with mycosis fungoides, from subjects dead from acute cardiac failure or traumatic injuries, as well as metastasis-free sentinel LNs of cutaneous melanoma served as positive and negative controls. RESULTS: TEN LNs showed absence of germinal centers but a moderate hyperplasia of the paracortical T cell zone. Immunohistochemistry did not reveal any distinctive aspect in LN cellular densities between TEN and other control conditions except for the factor-XIIIa+ dendritic cells which were dramatically reduced in numbers in TEN LNs. This rarefaction in LNs contrasted with the great number of these cells in the skin of the same patients. CONCLUSION: The structure of TEN LNs rules out the involvement of an antibody-mediated response. As dendritic factor-XIIIa+ cells are involved in most cutaneous T-cell-mediated responses, their depletion in TEN LNs could explain the sparse lymphoid cell infiltrate in lesional TEN skin. [less ▲]

Our aim was to study the inhibitory and facilitatory factors possibly accounting for the undetectable activity of the GnRH pulse generator in late fetal life in vitro and its awakening in early postnatal life. Gamma aminobutyric acid (GABA(A)) receptor antagonism using SR 95 531 did not cause any secretory pulse in fetal explants, whereas a significant stimulation of GnRH pulse frequency was obtained at 5 and 15 days. GnRH secretory response to repeated N-methyl-D-aspartate (NMDA) stimulation showed progressive disappearance, indicating that the inhibitory autofeedback was operating. GnRH release caused by glutamine was respectively 9% and 20% of that evoked by glutamate in fetal and 5-day-old rats whereas both amino acids were equally active at 15 days. Explants obtained after cesarean section performed at onset of labor did not show any secretory pulse, while pulses could be observed with explants obtained 2 h after vaginal delivery. Incubation of fetal explants with oxytocin (10(-8) M) or prostaglandin E-2 (PGE(2)) (10(-6) M) resulted in occurrence of GnRH secretory pulses. A facilitatory effect of the oxytocin was shown to persist on Days 1, 5, and 15 and inhibitory effects of an oxytocin receptor antagonist provided some evidence of endogenous oxytocin involvement. We conclude that, in the fetal rat hypothalamus, GnRH inhibitory autofeedback and GABAergic inputs do not account for the absence of pulsatile GnRH secretion in vitro. A low rate of glutamate biosynthesis from glutamine is a possibly limiting factor. Oxytocin and PGE(2) can play a facilitatory role in the postpartal occurrence of pulsatile GnRH secretion. [less ▲]
