Basic research in orbital and oculoplastic surgery.

This review summarizes basic research in orbital and oculoplastic surgery during the past year. Innovative and exciting projects have been undertaken elucidating microscopic anatomy of the orbital septum, orbital lymphatics, and levator elastic fiber network. Eyelid anatomy as assessed by magnetic resonance imaging has been beautifully demonstrated. In the realm of orbital disease, several studies have provided potential alternative therapeutic modalities in the management of the anophthalmic socket. These particular studies range from the use of demineralized bone in the rabbit anophthalmic socket, to the use of bone graft to reconstruct the monkey orbital floor. Further elegant studies outline the velocity of ophthalmic artery flow, and potential applications of ocular thermography.

Dural cavernous sinus fistula: an unusual presentation.

This article describes a 22-year-old man who presented to the Howard University Hospital emergency room with acute onset of swelling, proptosis, and decreased vision in the right eye preceded by 24 hours of nausea and vomiting. The patient's visual acuity was count fingers in the involved eye with marked proptosis and limitation of ocular motility. There was no history given of any ocular or head trauma. A computed tomography scan of the orbits showed diffuse symmetric enlargement of the extraocular muscles of the right eye, felt to be consistent with an orbital inflammatory pseudotumor. The patient was treated with intravenous steroids initially, then placed on oral prednisone. After minimal improvement on the steroids, a selective external carotid angiogram showed a moderate-sized dural cavernous sinus fistula. The patient underwent selective embolization of the fistula with rapid resolution of periorbital edema and proptosis. Visual acuity was stabilized at 20/200 in the right eye. The differential diagnosis and pathogenesis of carotid cavernous sinus fistulas and the likely pathogenesis of the fistula in this case are discussed.

Competencies of liberal education in post R.N. baccalaureate students.

This article reports on the first phase of an ongoing longitudinal study designed to examine the competencies of liberal education as demonstrated in the personal and professional lives of post R.N. students returning to university to earn a baccalaureate degree in nursing by means of distance education. After one year of study at the baccalaureate level, significant differences were found in scores of the competencies of liberal education as demonstrated in the professional lives of the post R.N. subjects. There were no significant differences noted in competencies demonstrated in the personal lives of the subjects. The study contributes to the small but growing body of literature which is studying the impact of a liberal education on Post R.N. learners.
