Les psychodermatoses chez le chien

Source: OAI

ABSTRACT Les psychodermatoses canines s'extériorisent par des lésions dermatologiques, associées à un trouble comportemental profond : l'anxiété. Cette étude bibliographique envisage ces différentes manifestations cliniques : la plaie de léchage, le tournis avec mutilation de la queue, le léchage de l'anus, l'onychophagie, la succion des mamelles ou du flanc et l'effluvium télogène affectif. Leur étiologie est multifactorielle, mais en majorité due à un environnement stressant et anxiogène. Leur physiopathologie est complexe du fait de la dysrégulation des différents neurotransmetteurs du système nerveux central. Le diagnostic est établi après élimination de toutes les hypothèses non psychogènes et par l'examen comportemental. Le pronostic est fonction du stade évolutif de la maladie. Enfin, le traitement consiste dans la majorité des cas à l'association d'une médication et d'une thérapie comportementale.

    ABSTRACT: Canine saliva was tested for its bactericidal effects against pathogens relevant to the presumed hygienic functions of maternal grooming of the mammary and anogenital areas and licking of wounds. Both female and male saliva were bactericidal against Escherichia coli and Streptococcus canis but only slightly, and nonsignificantly, bactericidal against coagulase positive staphylococcus and Pseudomonas aeruginosa. E. coli is the cause of highly fatal coliform enteritis of neonatal mammals and E. coli and S. canis are the main pathogens implicated in neonatal septicemia of dogs. The bactericidal effects of saliva would facilitate the hygienic function of maternal licking of the mammary and anogenital areas in protecting newborns from these diseases. E. coli and S. canis along with coagulase positive staphylococcus and P. aeruginosa are among the common wound contaminants of dogs. Wound licking, and the application of saliva, would thus reduce wound contamination by E. coli and S. canis. The resistance of staphylococcus to bactericidal effects of saliva may be a factor in the high frequency (46 percent) with which coagulase positive staphylococcus was isolated from wounds compared with much lower frequency (9-17 percent) with which E. coli and S. canis were isolated.

    ABSTRACT: Antidepressant drugs can be an important component of the dermatologists' therapeutic armamentarium. When considering the use of psychotropic agents in dermatology two major factors should be considered: (1) the accurate diagnosis of the comorbid psychiatric disorder, and (2) the presence of proper indications for the use of antidepressant agents. Antidepressant drugs are used in the management of the psychiatric syndromes, which are most frequently comorbid with dermatologic disorders, i.e., Major Depressive Disorder, Obsessive-Compulsive Disorder, Body Dysmorphic Disorder, Post-traumatic Stress Disorder and Social Phobia. The antihistaminic and analgesic properties of some antidepressants such as doxepin and amitriptyline, are also of benefit in the treatment of some pruritic and neuralgic states. The specific guidelines, side effect profile, drug-drug interactions, and the most current indications should always be obtained for any particular antidepressant agent before it is prescribed.
