Exposure to ionizing radiation results in the expression of iNOS in ileum and colon, but only significantly increases iNOS activity in the ileum. Inducible NOS-derived NO may participate in acute, whole body radiation-induced ileal dysfunction, independently of the development of an inflammatory response.

Implantation of the Sensar AR40 IOL with the Unfolder system was easy to perform, and no serious complications occurred.

A 31-year-old female physician with bilateral myopia had unilateral myopic laser in situ keratomileusis in the right eye. The patient was overcorrected with the initial treatment and had 2 subsequent hyperopic treatments, resulting in central corneal irregularity. During the course of treatment, the patient was diagnosed with Sjögren's syndrome with marked keratoconjunctivitis sicca. The patient had anisometropia, aniseikonia, and monocular diplopia and was unable to tolerate contact lenses. Oral pilocarpine (Salagen) was prescribed, which improved salivation, lacrimation, and keratoconjunctivitis sicca. The patient was able to tolerate rigid gas-permeable contact lenses to achieve 20/20 visual acuity in both eyes and regain binocular vision.
