Factors influencing the evolving practice of obstetricians in eastern Wisconsin: a survey.

The purpose of this survey was to ascertain what prompts clinicians in eastern Wisconsin to change their obstetric practice. A survey was mailed to all clinicians doing obstetrics for a nonprofit organization that performs over 11,000 deliveries in 10 hospitals. Of the 185 surveys mailed, 90 (49%) practicing obstetricians returned it.

Self-inserted sphenoid sinus foreign bodies.

This report describes the case of a patient who inserted 3 foreign bodies into her right sphenoid sinus. The possible consequences of sphenoid sinus foreign bodies are described, as well as the importance of a psychiatric workup in such cases.

Computer coregistration of positron emission tomography and magnetic resonance images in head and neck cancer.

Purpose: Early experience has shown that positron-emission tomography (PET) is a useful technique for the detection of occult squamous cell carcinoma of the head and neck. Although highly sensitive, PET lacks definition of anatomic detail and therefore does not localize pathology precisely. To circumvent this limitation, a computerized coregistration technique has been developed at the University of California-Los Angeles to correlate PET and magnetic resonance images (MRI).

Inhibition of lymphocyte function by head and neck carcinoma cell line soluble factors.

Background: Immunosuppression in patients with head and neck cancer is well recognized. Previous investigations have demonstrated graded immunosuppression that becomes more pronounced as lymphocyte activity is measured closer to the primary neoplasm. In fresh tumors, a soluble factor has been identified that may partly account for the observed graded immunosuppression.
