An Unexpected Cause of Sepsis: Keep Pursuing the Source of Infection.

An 86-year-old man was found with altered mental status, fever and aphasia. His physical exam revealed nuchal rigidity but no other meningeal signs. Because the patient's mental status was declining, he was intubated and placed in mechanical ventilation.

Functional analysis of non-hotspot AKT1 mutants found in human breast cancers identifies novel driver mutations: implications for personalized medicine.

The phosphatidylinositol 3-kinase (PI3-kinase)-Akt-mTOR pathway is mutated at high frequency in human breast cancer, and this pathway is the focus of active drug discovery and clinical investigation. Trials of personalized cancer therapy seek to leverage knowledge of cancer gene mutations by using mutations to guide the choice of targeted therapies. At the same time, cancer genome sequencing studies are identifying low frequency variants of unknown significance in known cancer genes, as well as genes of unknown function.
