Although collaboration with cultural and educational services is essential the focus of our review is certainly in medical concerns. We work with a fictional case to demonstrate how the procedure may be used (Container 2). Additional assets for doctors are provided in Container 3. Container 1: Preparing this review We each added towards the review regarding to your specialty. We chosen the most beneficial recent peer-reviewed books (using tools such as for example MEDLINE Embase and PubMed). The recommendations presented here are based on evidence from randomized controlled trials or systematic reviews if available. If there are gaps in such evidence recommendations are based on our expert opinion. Box 2: Applying the advances in clinical practice (fictional case) When Brian was 18 months his parents expressed concerns to their pediatrician about his social development. Brian was born at term by spontaneous vaginal delivery with weight and height at the 50th percentile and head circumference at the 97th percentile. Ultrasonography of his head showed no obvious abnormality and there were no neonatal complications. Brian achieved early developmental milestones as expected: social smiling at eight weeks PTK787 2HCl babbling by six months and walking by one year. His first words were at PTK787 2HCl 18 months. His mother noted that Brian did not always look when his name was called had minimal interest in PTK787 2HCl other children and had difficulty disengaging from certain toys such as model trains on a track. The results of an audiology assessment were normal. The pediatrician completed a Modified Checklist for Autism in Toddlers with the mother and Brian was found to be “at risk for autism.” She referred Brian to the local infant development-early PTK787 2HCl intervention service. Given his relative macrocephaly she ordered magnetic resonance imaging of his head; the results were normal. At 24 months Brian’s family returned to the pediatrician with additional concerns despite some gains made with early intervention services. Although his language development was progressing (three-word phrases and more than 100 words) his speech had become repetitive (i.e. repeating questions reciting dialogue from videos and using scripts mixed with spontaneous language in his everyday life). He seemed interested in other children but he never approached on his own and needed much encouragement to respond positively to another child’s approach tending to play near other children with minimal interaction. He could stay for hours with his face to the carpet watching model trains. He did not engage in pretend play (e.g. “feeding” stuffed animals). The pediatrician observed Brian playing repetitively with toys in the waiting room and interacting minimally with other children. Eye contact was present but variable. She attempted to draw Brian’s attention to a toy on a shelf by engaging his gaze and shifting to look at the toy but Brian failed to follow the look even when she also pointed. Another noisy child led to significant stress for Brian who tensed his body flapped his arms and repeated a script from a favourite cartoon as he walked away. The pediatrician diagnosed autism spectrum disorder (ASD) based on DSM-V criteria. She ordered a genomic microarray and referred the family to the local speech and language services and the autism early intervention program. The microarray report revealed a deletion of chromosome 1p36.23-p36.32 and suggested referral to a clinical geneticist. The geneticist advised PTK787 2HCl the pediatrician to order certain tests in advance including cardiac and renal ultrasonography thyroid testing and referral to an ophthalmologist. Renal ultrasonography showed a vesicoureteral malformation and the pediatrician referred Brian to urology. Thyroid studies suggested hypothyroidism prompting referral to pediatric endocrinology. Brian Gpc3 was seen by a clinical geneticist several months later. The deletion was not found in either parent and was presumed to be the cause of Brian’s difficulties. The geneticist reassured parents about the low risk of recurrence in a sibling. Commentary This diagnosis of ASD was made by the child’s pediatrician based on DSM criteria and the child was referred to community services. Practices related to diagnosis vary among provinces and territories and between.
