PURPOSE To describe a series of patients with lower eyelid epiblepharon associated with lower eyelid retraction. METHODS We retrospectively reviewed the medical records of patients who underwent surgery for lower eyelid retraction, epiblepharon, or thyroid-associated ophthalmopathy (TAO) between October 1999 and March 2007. Patients with both lower eyelid retraction and epiblepharon on preope...

duane’s retraction syndrome (drs) type i is often associated with esotropia (et) and face turn in those with fusion. this study was designed to delineate the quantitative relationship between the angles of eye deviation with that of face turn. ten patients with drs type i with et and face turn toward the deviated eye, who had central fixation, were chosen. esodeviation was measured by alternate...

BACKGROUND The number of retracted scientific publications has risen sharply, but it is unclear whether this reflects an increase in publication of flawed articles or an increase in the rate at which flawed articles are withdrawn. METHODS AND FINDINGS We examined the interval between publication and retraction for 2,047 retracted articles indexed in PubMed. Time-to-retraction (from publicatio...

purpose: to report clinical features, types, and results of surgery for duane’s retraction syndrome (drs). methods: this is an existing data study on the records of patients with drs. the study was conducted on the hospital records of patients who were referred for drs to a tertiacy eye center in tehran, iran during 8 years. the follow-up period after the surgery was at least 6 months. results:...

abstract fixed dental prosthesis success requires appropriate impression taking of the prepared finish line. this is critical in either tooth supported fixed prosthesis (crown and bridge) or implant supported fixed prosthesis (solid abutment). if the prepared finish line is adjacent to the gingival sulcus, gingival retraction techniques should be used to decrease the marginal discrepancy among ...

OBJECTIVES To correlate the recurrence of temporalis fascia graft perforation and retraction in adults and children after tympanoplasty for chronic tubotympanic otitis and deep attic retraction pockets with age, pathologic process, mucosal lesions, mucociliary transport time, chronic sinusitis, and lateral attic wall reconstruction. DESIGN Retrospective study. SETTING Tertiary referral cent...

Tonic stimuli can elicit rhythmic responses. The neural circuit underlying Aplysia californica consummatory feeding was used to examine how a maintained stimulus elicits repetitive, rhythmic movements. The command-like cerebral-buccal interneuron 2 (CBI-2) is excited by tonic food stimuli but initiates rhythmic consummatory responses by exciting only protraction-phase neurons, which then excite...

OBJECTIVE To compare the amount of anchorage loss of the maxillary posterior teeth and amount of retraction of the maxillary anterior teeth between en masse retraction and two-step retraction of the anterior teeth. MATERIALS AND METHODS The sample consisted of 30 female adult patients with Class I malocclusion and lip protrusion who needed maximum posterior anchorage. The sample was subdivide...

Swing-leg retraction, the backward rotation of the swing leg just prior to ground contact, is observed in human locomotion. While several advantages of swingleg retraction, like gait stability and perturbation rejection, are shown by conceptual models, there is currently very little experimental data on swing-leg retraction in human motion. In this paper, kinematic data for twenty-eight subject...
