Trends in lung cancer diagnosis and care among visible minorities and non-visible minorities in Canada.

BACKGROUND: Identifying factors that influence the diagnosis and treatment of lung cancer is an important public health initiative. Various sociodemographic factors, including race and ethnicity, may influence an individual's risk of developing lung cancer, as well as access to relevant diagnostic and therapeutic procedures. METHODS: Data from the 2006 Canadian long-form census were cross-linked with the Canadian Cancer Registry and hospital data to determine rates of lung cancer diagnosis among visible minorities and non-visible minorities in Canada, and to assess for differences in rates of hospital-based procedures pertaining to a lung cancer diagnosis based on visible-minority status. Individuals were allocated into six visible-minority categories, and separate results were generated nationally and across seven regions. Multivariate logistic regression controlled for relevant confounders. RESULTS: Rates of lung cancer were significantly lower among visible minorities versus non-visible minorities (329 versus 1108 cases per 100 000). This result is consistent across all visible-minority subgroups. Among those with a diagnosis of lung cancer, procedure rates were higher for all visible minorities nationally (53.4% [95% CI 53.2-53.6]). Multivariable analysis demonstrated higher procedure rates in general for visible minorities with a lung cancer diagnosis compared to non-visible minorities (OR 1.158 95% CI 1.053-1.273). INTERPRETATION: In Canada, visible minorities experience lower rates of lung cancer diagnosis than non-visible minorities. Among those with a lung cancer diagnosis, we did not identify any negative disparities in rates of relevant diagnostic or therapeutic procedures, based on visible-minority status.

Extraperitoneal rectal trauma in a patient with multiple gunshot wounds: A case report and literature review.

Penetrating rectal trauma is an uncommon presentation, particularly in centres with low rates of trauma, and requires a high index of suspicion to identify and treat. Management of penetrating rectal trauma has evolved over several decades and previously included proximal diversion, distal rectal washout, and presacral drainage as the primary surgical maneuvers to reduce mortality. Recently, a more conservative approach has been adopted, as the applicability of combat experience to the civilian setting has been questioned. In this report, a case of extraperitoneal rectal injury in a patient with multiple gunshot wounds provides a backdrop for literature review and discussion of the modern diagnostic and management approaches to penetrating rectal trauma.
