Validation of an International Classification of Diseases, Ninth Revision Code algorithm for identifying Chiari Malformation type 1 surgery in adults.
The purpose of this study was to validate 2 ICD-9-CM code algorithms identifying patients undergoing CM-1 decompression surgery. It concluded that the ICD-9-CM code Algorithm 2 has excellent positive predictive value and good sensitivity to identify adult CM-1 decompression surgery.

Delay in diagnosis of invasive surgical site infections following knee arthroplasty versus hip arthroplasty.
The researchers compared time to diagnosis of invasive surgical site infection (SSI) following hip vs knee arthroplasty. They found that time to diagnosis of invasive SSI remained significantly shorter for hip than for knee arthroplasties after adjusting for age, pathogen virulence, and hospital surgical volume. They hypothesized that differences in symptom manifestation and disparities in access to care may contribute to the observed differential timing of diagnosis.

Breast implant-associated anaplastic large cell lymphoma: a systematic review.
The purpose of this study was to identify and analyze recently published cases of breast implant-associated anaplastic large cell lymphoma (ALCL), with an emphasis on diagnosis, staging, treatment, and outcomes. The researchers found that, of 54 cases, most patients presented with a seroma, approximately half were associated with the capsule, most presented as stage IE, and all but one case were ALK-negative. Most patients received chemotherapy and radiation therapy, and 11 percent received stem cell transplants. Approximately one-quarter recurred, and 9 percent died.
