Question A 30-month-old patient in our clinic has had 4 episodes of acute otitis media (AOM) in the past 6 months. Should I refer the child and family to an ear, nose, and throat surgeon to consider tympanostomy tube placement, or should we continue medical management with antibiotics?Answer Acute otitis media is common among children in Canada, particularly those younger than 3 years of age. Recurrent AOM (3 or more episodes of AOM in a 6-month period or 4 or more episodes of AOM in a 12-month period) is also common in this age group. Routine immunization of infants and children in Canada with pneumococcal conjugate vaccines (initially the 7-valent PCV7 and more recently the 13-valent PCV13) considerably reduced the overall incidence of AOM. Tympanostomy tube placement decreases the incidence of AOM compared with medical management. However, the procedure is no longer superior to medical management after a 2-year period. Both tympanostomy tube placement and medical management are valid options for children with recurrent AOM, and shared decision making with caregivers is recommended.
Question Several parents have recently asked me if oxytocin would be helpful for treating their children with autism spectrum disorder (ASD). What do we currently know about the use of oxytocin for the treatment of children with ASD?Answer Autism spectrum disorder is prevalent among children in Canada, with most affected children experiencing difficulties with social function. Behavioural and educational interventions are the first-line treatments for children with ASD. Multiple studies of oxytocin in children with ASD from the past 2 decades provide equivocal results related to social functioning, and a recent large study did not show benefit from treatment with oxytocin. Small sample sizes and differences in participant age, oxytocin formulation and dose, treatment duration, outcome measures, and analytic methods may help explain some of these disparities. The fact that ASD has a range of clinical presentations may also contribute to mixed results. The use of oxytocin has limited benefit in changing social function in children with ASD and there is no support for its current use in the treatment of this population.
Question Plusieurs parents m'ont récemment demandé si l'ocytocine serait utile pour traiter leur enfant atteint du trouble du spectre de l'autisme (TSA). Que savons-nous sur l'ocytocine pour le traitement des enfants atteints du TSA?Réponse Le trouble du spectre de l'autisme est fréquent chez les enfants canadiens, et la plupart des enfants atteints éprouvent des difficultés à fonctionner socialement. Les interventions comportementales et éducatives sont les traitements de première intention pour les enfants atteints du TSA. De nombreuses études menées depuis 20 ans sur l'ocytocine chez les enfants atteints du TSA ont donné des résultats équivoques en matière de fonctionnement social, et une récente étude d'envergure n'a pas montré que le traitement par l'ocytocine était bénéfique. Certaines de ces disparités pourraient s'expliquer par la taille réduite des échantillons et les différences d'âge entre les participants, la préparation et la dose d'ocytocine, la durée du traitement, les paramètres d'évaluation et les méthodes analytiques. Le fait que le tableau clinique du TSA soit si vaste contribue également aux résultats mitigés. L'utilisation de l'ocytocine a des bienfaits limités sur la modification du fonctionnement social chez les enfants atteints de TSA, et rien n'appuie son emploi courant pour le traitement de cette population.
