The objective of this study was to assess the performance of sodium hyaluronate eye drop for eight weeks in patients with DED. PATIENTS AND METHODS This was a multi-centre, open-label, uncontrolled clinical trial carried out at different centres of Pakistan, from August 2009 to November 2010. A tota...

Foreign body aspiration (FBA) is a dangerous and potentially life-threatening event. We report the case of a 24-month old boy, who was initially presented with an episode of obstructive bronchitis to the family pediatrician. Then, while being treated with empiric antibiotics, he aspirated a peanut. Although resulting in a coughing episode, the mother did initially not ascribe any relevancy to i...

In a foreign currency exchange market, there are highdensity data streams. The present approaches for visualization of this type of data cannot show us a figure with targeted both local details and global trend information. In this paper, on the basis of features and attributes of foreign currency exchange trading streams, we discuss and compare multiple approaches including interactive zooming...

A survey of 198 patients (210 eyes) with intraocular or intraorbital foreign bodies is presented. Most were males between 16 and 30 years of age, and 6.1% of cases were bilateral. The commonest cause was a flying particle while using a hand hammer, followed by fragments of bomb and mine blasts. Intraorbital foreign bodies occurred in 78 eyes and intraocular foreign bodies in 132 eyes. Irreparab...

The reliability of aqueous analysis by the atomic absorption spectrophotometer for copper ion content in samples from eyes containing intravitreal pure copper particles was investigated. It was demonstrated that values of copper ions rose well above the normal in the aqueous as well as in the vitreous of such eyes. The standard deviations of the mean values were generally high. It was also foun...

Human body normally reacts to the presence of foreign bodies by inflammation, fibrosis, and infection. Such reactions may negatively affect the function of implant or may harm the host. Body reactions lead to alterations in the mechanical properties, such as increase in the stiffness of the tissue. Here we develop a noninvasive method for studying changes in the mechanical properties of tissue ...

Foreign body ingestion is a common clinical situation that is primarily diagnosed by emergency clinicians. Most foreign bodies can be evacuated without difficulty. Although rare, magnets that reach the lower intestinal tract may cause complications such as intestinal fistula formation, perforation, volvulus or appendicitis. We report herein a two-year-old girl who was admitted to our department...
