Alone in a Crowd – Ace QBank Canada

A 5-year-old boy is brought to the clinic by his mother due to concerns about his behaviour. At daycare, he isolates himself and does not engage with peers. He avoids eye contact, does not respond when his name is called, and rarely uses gestures to communicate. His mother reports repetitive rocking movements and significant distress when his routine is interrupted. His speech is limited, and he does not engage in imaginative or pretend play. He is unusually sensitive to loud noises and has an intense fixation with spinning objects.

Making the proper diagnosis is one of the most important aspects of any medical student’s or junior doctor’s clinical training and hence we created Clinical Edge Cases.

Ace Qbank Clinical Edge helps our students put their knowledge of symptoms and physical findings to test by applying clinical reasoning and assessment concepts to a series of common clinical vignettes. Problem-based learning is being used to focus on the cause behind the presentation of a simulated clinical case.

Each simulated Clinical Edge case contains a list of common causes of the presented condition, offers abundant references to the presented case, making additional information easy to find
