CAR Peer Learning Guide.

Peer learning is a quality initiative used to identify potential areas of practice improvement, both on a patient level and on a systemic level. Opportunities for peer learning include review of prior imaging studies, evaluation of cases from multidisciplinary case conferences, and review of radiology trainees' call cases. Peer learning is non-punitive and focuses on promoting life-long learning.

Reversible cerebral vasoconstriction syndrome: an important and common cause of thunderclap and recurrent headaches.

Reversible cerebral vasoconstriction syndrome is an intracranial vascular manifestation of a wide variety of diseases. It is the second most common cause of thunderclap headache, the most common cause of recurrent severe secondary headaches, and, in patients <60 years of age, has been reported as the commonest cause of isolated convexity subarachnoid haemorrhage. Radiologically, its key feature is vasoconstriction of the intracranial vessels, a dynamic process that is typically maximal at 2 weeks, varies in its distribution over the course of the disease, and typically resolves after 3 months.

A radiological approach to benign and malignant lesions of the mandible.

There is a wide range of pathological conditions that affect the mandible. Although some lesions demonstrate characteristic imaging features, many of the pathological processes encountered in the mandible often exhibit similar imaging appearances resulting in uncertainty for the reporting radiologist. Many mandibular lesions remain impossible to distinguish without histological analysis.

Imaging findings in recurrent extramedullary leukaemias.

Acute leukaemias are relatively common malignancies. Treatment has advanced significantly in the recent past and there has been improved patient survival. This improved initial response is leading to an increasing number of cases of relapse.

Imaging spectrum of sudden athlete cardiac death.

Sudden athlete death (SAD) is a widely publicized and increasingly reported phenomenon. For many, the athlete population epitomize human physical endeavour and achievement and their unexpected death comes with a significant emotional impact on the public. Sudden deaths within this group are often without prior warning.

Incidence of parasomnias in children with obstructive sleep apnea.

The incidence of parent-reported parasomnias in children with obstructive sleep apnea (OSA) is increased in comparison with a normative age-matched sample of children but is not higher than that for a similar clinical sample of children with a diagnosed behavioral sleep disorder.

Child temperament, parenting discipline style, and daytime behavior in childhood sleep disorders.

Fifty-two children without significant sleep disturbance seen at a primary care clinic for well-child care were compared on measures of temperament, parenting style, daytime behavior, and overall sleep disturbance to three diagnostic subgroups identified in a pediatric sleep clinic: children with obstructive sleep apnea (n = 33), parasomnias (night terrors, sleepwalking, etc.) (n = 16), and behavioral sleep disorders (limit-setting disorder, etc.) (n = 31).

Relationship between substance use and self-reported injuries among adolescents.

High school students (n = 1983), 14-18 years olds, were surveyed regarding the incidence of injury and substance use at the time of the injury in the prior 6 months. Alcohol or other drugs were reported particularly often for falls, cuts, and gun and assault injuries. Alcohol or other drugs were reported to be involved in a substantial proportion of injuries resulting in medical care, most notably for gunshots (70%), pedestrian injuries (42%) and physical fights (38%).

Risk taking, reported injury, and perception of future injury among adolescents.

Investigated the relationships among self-reported injury, risk taking, and perception of injury risk in a sample of 1,426 adolescents, 14 to 18 years old. Both risk taking and injury were higher in males than females across age groups. Having a friend injured the same way was the strongest predictor of injury, accounting for 28% of the variance.
