BACKGROUND AND PURPOSE Because DTI can provide good markers of white matter pathology, it could be useful in differentiating white matter changes of INPH from those of other dementias. The aim of this study was, by using DTI, to compare the characteristic white matter changes in INPH with those in AD, subcortical vascular dementia, and healthy control subjects. MATERIALS AND METHODS Sixteen p...

SUMMARY Performing secondary rhinoplasty in patients who underwent primary rhinoplasty using a silicone implant is difficult due to thinning of nasal skin and formation of a capsule. Excess capsule formation can cause capsular contracture, resulting in short nose deformity or implant deviation, migration, or implant demarcation. Revision rhinoplasty using a capsular flap, dorsal silicone implan...

The cervical facet joints are a source of pain in some chronic whiplash patients. Clinical data show that a head-turned posture increases the severity and duration of whiplash-related symptoms. The objective of this study was to quantify strains in the facet capsule during whiplash-like loading with an axial intervertebral pre-torque simulating an initial head-turned posture. These strains were...

PURPOSE To determine the incidence of and risk factors for posterior capsule rupture and vitreous loss during phacoemulsification performed by ophthalmology residents. SETTING Academic ophthalmology resident training center, Tehran, Iran. DESIGN Cross-sectional study. METHODS This study included patients who had phacoemulsification by ophthalmology residents from August 2010 to August 201...

Arthrofibrosis is a major obstacle to restoring joint function after trauma. The objective of this study was to evaluate montelukast, forskolin, and triamcinolone as possible means of prophylaxis against the formation of arthrofibrosis. Forty-eight rats underwent surgical knee trauma with post-operative immobilization in full flexion. The treatment groups were: control (CTL), oral montelukast (...

Objective To evaluate intraocular scattering in eyes with posterior capsule opacification by means of an objective scatter index (OSI) obtained from double-pass images of optical quality assessment system (OQAS TM II) and to determine the indication for laser capsulotomy when patients report visual disturbances without decreased visual acuity. Methods In this prospective, observational, and n...

PURPOSE To evaluate the safety and efficacy of staining the posterior capsule with trypan blue during capsulorhexis in pediatric cataract surgery. PATIENTS AND METHODS This was a prospective randomized comparative study carried out at Alpha Vision Center, Zagazig, Egypt. This study included 2 groups of children with pediatric cataract randomly allocated to undergo irrigation and aspiration. I...

We retrospectively evaluated the clinical characteristics and surgical outcomes of 20 pseudophakic retinal detachment (RD) patients (20 eyes) and 17 aphakic RD patients (17 eyes). Males were predominated in both groups. The time interval between cataract extraction and RD was 31 months on average in the pseudophakic group, 32 months with intact posterior capsule and 27 months with ruptured post...

Acute isolated hemiataxia is in most cases due to infratentorial (cerebellar) stroke. It has only twice been described in supratentorial stroke--namely, after thalamic infarction and a capsular haemorrhage. Three patients with isolated hemiataxia after a supratentorial brain infarct are described. These patients were seen in a period of five years during which 899 patients with a first supraten...
