Abstract:
Determining the risk of progression to systemic lupus erythematosus (SLE) among patients diagnosed with discoid lupus erythematosus (DLE), and the time frame of this risk, are important clinical questions. Past reports have demonstrated a wide time frame of progression from DLE to SLE, with mean time to progression of approximately 8 years. Using data obtained from an academic lupus centre, we identified 32 patients who progressed from DLE to SLE. In our cohort, we found that the median time to progression from DLE to SLE was 453 days, much sooner than previously reported. We believe this information can help inform clinicians on monitoring visit intervals and how best to counsel patients on SLE progression.

Linear time-invariant Systems
The input-output behavior of an LTI system can be fully defined by its response to an impulsive excitation at its input. Once this impulse response is known, the system's reaction to any other input can be...

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
