Urban and rural differences in outcomes of head and neck cancer.

Objectives/hypothesis: To assess for potential urban and rural disparities in head and neck cancer (HNC) outcomes within a single-payer healthcare system.

Study Design: A large retrospective population-based cohort analysis of consecutive HNC patients treated in British Columbia, Canada between 2001 and 2010 was conducted.

Methods: All patients diagnosed with HNC from 2001 to 2010 and referred to any one of five British Columbia Cancer Agency centers for management were reviewed.

Correlation between County-Level Surgeon Density and Mortality from Colorectal Cancer.

Purpose: We aimed to explore the effect of county-level general surgeon (GS) and colorectal surgeon (CS) density on colorectal cancer (CRC) mortality and to identify additional county characteristics associated with outcomes.

Methods: Using data from the Area Resource File, US Census, and National Cancer Institute, we developed multivariate regression models to determine the effect of density of GS and CS on CRC death between 2005 and 2009 while controlling for CRC incidence, county demographics, and other socioeconomic factors.

Results: In total, we included 1767 counties: Mean CRC incidence and death rates were 64.

Community-based newborn hearing screening programme for early detection of permanent hearing loss in Iran: an eight-year cross-sectional study from 2005 to 2012.

Objectives: We here present the results of the first eight years of the newborn hearing screening programme in Iran, with a view to establishing the prevalence of hearing impairment among infants, and the efficacy of the programme.

Methods: A total of 3,350,995 infants were screened using the series method of transient evoked otoacoustic emissions (TEOAEs)/automated auditory brainstem responses (AABRs), between 2005 and 2012. The infants were first tested for TEOAEs (three times).
