Exposure to topical apraclonidine in children with glaucoma.

Purpose: The topical alpha-2 adrenergic agonist, brimonidine, although effective at intraocular pressure (IOP) reduction in adults, is contraindicated in infants/small children due to severe systemic side effects. The topical alpha-2 adrenergic agonist apraclonidine, used for short-term IOP reduction in adults, and described for Horner's syndrome testing, has recently been reported to cause systemic side effects in children. We have used topical apraclonidine 0.

Microbial keratitis following corneal transplantation.

Purpose: To study clinical and microbiologic characteristics of corneal infections following penetrating keratoplasty (PK).

Design: Retrospective case series.

Methods: Medical records of patients who presented to Duke University Eye Center from January 1, 1999 to July 1, 2005 with microbial keratitis after PK were reviewed.

Collagen-rich crystalloids in a scarred vascularized cornea.

Collagen-rich crystalloids, also referred to as collagenous crystalloids, are uncommon findings in benign salivary gland tumors with myoepithelial differentiation and in cutaneous neoplasms. Herein, we report the presence of collagen-rich crystalloids in the scarred, vascularized cornea of a 56-year-old woman. The patient underwent penetrating keratoplasty, and microscopic examination of hematoxylin-eosin-stained sections disclosed large aggregates of refractile material within the corneal stroma.

Polysensory interactions along lateral temporal regions evoked by audiovisual speech.

Many socially significant biological stimuli are polymodal, and information processing is enhanced for polymodal over unimodal stimuli. The human superior temporal sulcus (STS) region has been implicated in processing socially relevant stimuli--particularly those derived from biological motion such as mouth movements. Single unit studies in monkeys have demonstrated that regions of STS are polysensory--responding to visual, auditory and somato-sensory stimuli, and human neuroimaging studies have shown that lip-reading activates auditory regions of the lateral temporal lobe.

Laparoscopic repair of a Morgagni hernia presenting with syncope in an 85-year-old woman: case report and update of the literature.

An 85-year-old woman was transferred from her local hospital for cardiac evaluation after presenting with repeated episodes of syncope during bowel movements. A thorough evaluation revealed no cardiac abnormalities but did reveal a Morgagni hernia with transverse colon in the mediastinum. She underwent laparoscopic reduction of the colon and repair of the hernia with mesh and had a rapid and uneventful recovery.
