Schmidt, Meic H.; Schmidt, Richard H. | Nerve sheath tumors involving the sacrum | Nerve sheath tumors that involve the sacrum are rare. Delayed presentation is common because of their slow-growing nature, the permissive surrounding anatomical environment, and nonspecific symptoms. Consequently, these tumors are usually of considerable size at the time of diagnosis. The authors di... | Nerve sheath tumor; Schwannoma | 2003 |

Schmidt, Meic H. | Repeated operations for infiltrative low-grade gliomas without intervening therapy | Progression of infiltrative low-grade gliomas (LGGs) has been reported previously. The limitations of such studies include diverse histological grading systems, intervening therapy, and the lack of histological confirmation of malignant tumor progression. The aim of this study was to determine tumo... | Infiltrative low-grade gliomas; LGG; Tumor progression; Repeated operations; Tumor recurrence | 2003 |

Kestle, John R. W. | Tracking resident work hours: available software is not yet ideal, but it's helpful | An ideal system would be completely passive and would allow more detailed tracking of activity inside the hospital.
