BACKGROUND: Although safe surgical access to the cavernous sinus is related to understanding the anatomical and ethnic variants of the prechiasmatic sulcus and the optic strut, there remains a paucity of studies of the morphology and the bony relationships in the region. The present study provides a systematic morphological and morphometric analysis of the sulcal region and the optic strut anatomy and their relations in a Greek population. METHODS: The interoptic distance, length of planum sphenoidale, sulcal length and sulcal angle was determined in 96 Greek adult dry skulls...

From the 1920s to the 1950s, California sterilized approximately 20,000 people in state homes and hospitals based on a eugenic law that authorized medical superintendents to perform reproductive surgeries on patients deemed unfit and "suffering from a mental affliction likely to be inherited." Working with a unique resource - a dataset created from 19,000 sterilization recommendations - my team and I have reconstructed patterns and experiences of institutionalization of sterilizations. This article presents several of our important initial findings related to ethnic and gender bias in sterilization policies, and reflects on the relevance of the history for contemporary issues in genomics and social justice...

INTRO: While the ACA expanded Medicaid access, it is unknown whether this has led to greater access to complex surgical care. Evidence on the effect of Medicaid expansion on access to surgical cancer care, a proxy for complex care, is sparse. Utilizing New York's 2001 statewide Medicaid expansion as a natural experiment, we investigated how expansion affected utilization of surgical cancer care among beneficiaries overall and among racial minorities. METHODS: The New York (NY) State Inpatient Database (1997-2006), we identified 67,685 non-elderly adults (18-64 years) who underwent cancer surgery...
