INTRODUCTION Usher syndrome is a genetically heterogeneous condition and represents the most common cause of inherited combined vision and hearing loss. Deficits manifest as sensorineural hearing loss that typically develops at a young age and retinitis pigmentosa that can lead to peripheral vision loss and night blindness. As a result, this syndrome can have a significant impact on a patient's...

background: interaction between local anesthetic solution, lidocaine hydrochloride (with and without adrenaline), and root canal irrigants such as sodium hypochlorite (naocl), ethylene diamine tetra-acetic acid (edta), and chlorhexidine (chx) has not been studied earlier. hence, the purpose of this in vitro study was to evaluate the chemical interaction between 2% lidocaine hydrochloride (with ...

PURPOSE To assess the safety and outcome of single-piece posterior chamber intraocular lens (PC-IOL) implantation in the ciliary sulcus following posterior capsular rupture during cataract surgery. METHODS Patients with posterior capsular rupture during cataract surgery with a single-piece acrylic IOL implanted into the ciliary sulcus were studied. Complete ocular examinations were performed ...

Abstract: Cold working performed before an aging treatment has a significant effect on size and amount of precipitate produced. This could be caused by the increase in defect density, such as vacancies and dislocations. In this research, the Al-Cu-Si alloy was solution-treated, wear-tested and then artificially aged for a period of 1–5 h. Changes in the amount of precipitate, in the lattice par...

It 'is suggested that, where cataract has developed in cases of sympathetic ophthalmia, fairly early operation might be undertaken when the slit-lamp does not show undue inflammation and theacute recu.rrences have subsided, despite the presence of keratic precipitates and a slight flare. The 'irido-capsular membrane may be "softe'r and an opening made more easily to lift out the lens. The same ...

A longitudinal population study of 1462 women aged 38-60 was carried out from 1968-9 to 1980-1 in Gothenburg, Sweden. The initial and follow up examinations included questions concerning history of diabetes and antihypertensive treatment. A considerably increased risk of developing diabetes was observed for subjects with hypertension taking diuretics (895 patient years), subjects taking beta bl...
