MPA is an important contraceptive and anticancer drug especially for treatment of breast cancer and it is the first time to study the different conditions affecting its stability. MPA was subjected to different variables such as solvent type, pH and the time subjected to UV light. Factorial design has been used during forced degradation to determine significant factors responsible for degradation and to optimize degradation conditions reaching maximum degradation. Factors responsible for forced degradation were statistically evaluated using Bubble and Surface plots. Variables proved to be significant (p less then 0.05) and the suggested model represented a perfect example for indicating the efficiency of factorial designs in optimizing the degradation conditions that give maximum percent of degradation. We investigated also the solubility and stability profiles of MPA in aqueous solutions. Stability study results showed a very low stability profile of MPA in all the aqueous solutions with rapid degradation rate more than other solvents. The current research may contribute to enrich the knowledge of the physicochemical properties of this drug for exploring its full anticancer potential in the future. OBJECT Up to 30 % of patients with epilepsy are medically intractable, defined as persistent seizures despite 2 or more appropriate anti-seizure medications (ASMs) at therapeutic doses. Such patients require non-pharmacologic management that often includes epilepsy surgery. This paper aims to assess the pre-operative ASM use patterns of patients who were surgically managed. METHODS Retrospective review of children who underwent surgery for epilepsy at Boston Children's Hospital between January 2010 and Decembe
