L’alopécie est un trouble courant qui se manifeste habituellement sur le cuir chevelu, mais qui, dans sa forme sévère, peut s’étendre à tous les poils du corps.</p> <p>L’alopécie touche 1,7 % des gens avant l’âge de 50 ans.</p><h2>À retenir</h2> <ul><li>La pelade provoque la chute des cheveux.</li> <li>Le médecin diagnostiquera la pelade en examinant votre enfant.</li> <li>Il arrive parfois que les cheveux repoussent d’eux-mêmes.</li> <li>Il existe des traitements qui aideront au traitement des plaques dégarnies existantes, mais ils ne peuvent pas empêcher la formation d’autres plaques.</li> <li>Si votre enfant est gêné à cause de la pelade, le fait de changer de coupe de cheveux ou de porter une perruque peut l’aider.</li></ul><h2>Causes de la pelade</h2><p>On ne sait pas exactement ce qui cause la pelade, mais ce trouble semble être le résultat d’un processus auto immun. Cela signifie que le système immunitaire s’attaque aux follicules pileux par erreur. Le follicule est l’enveloppe dans l’épaisseur de la peau qui fait pousser le cheveu et le tient. Lorsqu’il est attaqué, il abandonne le cheveu. Les dommages ne sont pas irréversibles. Le follicule peut encore fonctionner et faire pousser un cheveu. </p> <figure> <span class="asset-image-title">Coupe transversale de la peau</span> <img src="https://assets.aboutkidshealth.ca/akhassets/hair_follicle_MED_ILL_FR.jpg" alt="" /> <figcaption class="“asset-image-caption”"> Les follicules pileux se situent à la base de la peau.</figcaption></figure> <p>L’évolution de la pelade est différente d’un patient à l’autre. Il est difficile de prédire exactement ce qui se produira dans le cas de votre enfant.</p><h2>Comment diagnostiquer la pelade</h2> <p>Le médecin de votre enfant diagnostiquera la pelade en examinant votre enfant et en parlant à votre famille. Habituellement, il n’est pas nécessaire de faire des tests pour diagnostiquer ce trouble.</p> <p>Chez les gens atteints de la pelade, le système immunitaire peut aussi s’attaquer à d’autres organes, comme la glande thyroïde et la glande surrénale. Donc, votre médecin demandera que des tests soient effectués afin de savoir si ces dernières ont été endommagées.</p><h2>Traitement médical de la pelade</h2> <p>Au début, votre médecin peut décider de ne pas traiter votre enfant contre la pelade. Il arrive parfois que les cheveux repoussent d’eux-mêmes. Tout simplement attendre peut se révéler la meilleure option.</p> <p>La majorité des petites plaques isolées de pelade ont de bonnes chances de repousser avec un traitement. De nouvelles plaques peuvent se développer dans les semaines et les mois qui suivent. Même si le traitement provoque une réaction positive, il est possible que les cheveux chutent de nouveau après une période de repousse.</p> <p>D’autres traitements peuvent favoriser le traitement des zones dégarnies existantes, mais ne peuvent pas empêcher la formation d’autres plaques. Voici certains de ces traitements :</p> <ul><li>L’application d’une crème stéroïde sur les zones dégarnies.</li> <li>Des injections de corticostéroïdes entre les couches de la peau. Elles sont aussi appelées injections intradermiques. Elles aident à supprimer le système immunitaire de sorte que l’organisme cesse de s’attaquer aux follicules pileux. Il diminue également l’enflure.</li> <li>Les allergènes de contact sont des médicaments qui provoquent une réaction allergique, ce qui provoque la pousse des cheveux. Ce médicament est souvent à base de diphenylcyclopropenone (diphencyprone) ou DPCP.</li></ul> <p>Alopecia universalis ne répond pas aussi bien aux traitements médicaux.</p><h2>Look Good Feel Better Centre</h2> <p>Princess Margaret Hospital</p> <p>3-642, 610 University Avenue</p> <p>Toronto, ON M5G 2M9</p> <p>Contact: Zain, wig specialist/coordinator</p> <p>Telephone: 416-946-6596 and 416-946-2075</p> <p>Fax: 416-946-2077</p> <p>E-mail: wig.salon@uhn.on.ca</p><h2>Documentations concernant la pelade</h2> <p>DermNet NZ: The dermatology resource : <a href="http://www.dermnetnz.org/" target="_blank">www.dermnetnz.org</a> (disponible en anglais seulement).</p> <p>National Alopecia Areata Foundation : <a href="http://www.naaf.org/" target="_blank">www.naaf.org</a> (disponible en anglais seulement).</p> <p>L’Association canadienne de dermatologie a une liste de groupes de soutien aux patients : <a href="http://www.dermatology.ca/french/patients_support.html" target="_blank">http://www.dermatology.ca/french/patients_support.html</a></p> <p>Perruques : <a href="http://www.locksoflove.org/" target="_blank">www.locksoflove.org</a> (disponible en anglais seulement).</p>

Be honest and open and support your child. Knowledge is power and comfort. </li> <li>Discuss the situation with your child's principal and teacher. If they know what your child has, they will be more likely to support your child. Give your child the option of informing classmates. </li> <li>Model good problem-solving and ways to cope. This means that it is all right to show and share your feelings. It is important that you address the feelings of both you and your child. If you and your child have a hard time coping and it affects your every day life, you may want to consider speaking with a counselor.</li> <li>Listen to your child. It is important that your child has someone that they trust and talk to. The person can be a family member, friend or a counselor.</li> <li>Encourage your child to pursue things they love and guide them towards activiites that will help them feel good about themselves. Provide your child with positive messages and praise. Your words have a great impact on how your child feels about themself. Self-esteem is crucial. </li> <li>Give your child the choice to interact with other children who have alopecia areata. This will allow them to share their experiences and know they are not alone. </li> <li>Another way to cope with the disese is to minimize its effect on your child's appearance. Your child may want to wear a wig or bandana. </li> </ul><h2>Look Good Feel Better Centre</h2> <p>Princess Margaret Hospital</p> <p>3-642, 610 University Avenue</p> <p>Toronto, ON M5G 2M9</p> <p>Contact: Zain, wig specialist/coordinator</p> <p>Telephone: 416-946-6596 and 416-946-2075</p> <p>Fax: 416-946-2077</p> <p>E-mail: wig.salon@uhn.on.ca</p><h2>Alopecia resources</h2> <p><a href="http://www.dermnetnz.org/">DermNet NZ: The dermatology resource</a></p> <p><a href="http://www.locksoflove.org/">Locks of love</a><br></p> <p><a href="https://www.naaf.org/">National Alopecia Areata Foundation</a><br></p>https://assets.aboutkidshealth.ca/akhassets/hair_follicle_MED_ILL_EN.jpgAlopecia areata (hair loss)
