Morbid Obesity in Total Knee Arthroplasty: Joint-Specific Variance in Outcomes for Operative Time, Length of Stay, and Readmission.

Background: It is increasingly apparent that the effect of obesity in arthroplasty is joint-specific. This study evaluates the effects of morbid obesity on primary total knee arthroplasty by comparing short-term outcomes between a morbidly obese (body mass index ≥40 kg/m) and a normal weight (body mass index 18.5-<25 kg/m) cohort at our institution between January 2003 and December 2010.

Morbid Obesity in Total Hip Arthroplasty: Redefining Outcomes for Operative Time, Length of Stay, and Readmission.

Background: The incidence of obesity among patients presenting for elective total hip arthroplasty (THA) has increased in the last decade, and the relationship between obesity and the need for joint arthroplasty has been demonstrated. This study evaluates the effects of morbid obesity on outcomes after primary THA by comparing short-term outcomes in THA between a morbidly obese (body mass index [BMI] ≥40) and a normal weight (BMI, 18.5 to <25) cohort at our institution between January 2003 and December 2010.

An Australian cohort of 210 patients with multiple invasive squamous cell carcinomas: risk factors and associated increased risk of melanoma and internal malignancies.

Background: Patients with a history of non-melanoma skin cancer (NMSC) have a 50% risk of developing subsequent NMSC.(13) Currently there are limited data on the association between multiple squamous cell carcinomas (SCC) and the risk of other cancers, including melanomas.

Objective: To assess the risk factors in a cohort of 210 Australians with a history of multiple invasive SCC, focusing on the association between multiple SCC and other cancers.
