A 59-year-old woman self presented to the emergency department with a painful right eye following a motor vehicle accident. She had reduced visual acuity and the eye had an alkaline pH with complete corneal uptake of fluorescein. Diagnosis of corneal abrasion and alkali burn to her right eye secondary to inflation of a driver's automobile airbag was made. The eye was irrigated with normal salin...

INTRODUCTION One of the leading causes of damage to the gastrointestinal tract in children is caustic ingestion which is sometimes life-threatening. The most reliable way to study the severity and extent of damage is endoscopy, which can be harmless in terms of time and technique. The aim of this study was to investigate, evaluate and compare clinical findings and endoscopic results of caustic ...

purpose: to evaluate the prevalence of acute ocular chemical injuries in patients referred to labbafinejad medical center (lmc) over a period of one year. methods: all patients with chemical burns referred to lmc emergency ophthalmology service were included in the study. demographic characteristics and information regarding the burn were obtained. visual acuity assessment and slit lamp examina...

purpose: to evaluate the role of amniotic membrane transplantation (amt) in acute ocular chemical burns. methods: patients with grade ii-iv (gii-giv) ocular chemical burns (roper-hall classification) of less than two weeks’ duration underwent amt in addition to medical therapy. patients were followed for at least 6 months and evaluated for ocular pain, visual acuity, epithelial defect healing, ...

Flue gas desulfurization is commonly known as FGD and is the technology used for removing sulfur dioxide (SO2) from the exhaust combustion flue gases of power plants that burn coal oroil to produce steam for the turbines that drive their electricity generators. The most common types of FGD contact the flue gases with an alkaline sorbent such as lime or limestone. As sulfur dioxide is responsibl...

Most Pseudomonas aeruginosa strains produce exotoxin A and two extracellular proteases (elastase and alkaline protease). Exotoxin A is a lethal toxin that inhibits protein synthesis in mammalian cells by the same mechanism as diphtheria toxin. It is generated in clinical and experimental animal infections. Passive or active immunization against this toxin gives significant protection against ex...

burns are injuries which may require long hospitalization and may result in important impairment and disability. burn injuries are still common especially in developing countries. assessment of the epidemiology of burns is very important for introduction of preventive methods. this study was conducted in yazd to assess and describe the epidemiology of burns including its main causes, and its de...

The aim of this study was to investigate the effects of subconjunctivally administered mesenchymal stem cells (MSCs) on corneal wound healing in the acute stage of an alkali burn. A corneal alkali burn model was generated by placing a piece of 3-mm diameter filter paper soaked in NaOH on the right eye of 48 Sprague-Dawley female rats. 24 rats were administered a subconjunctival injection of a s...

this study was conducted to determine the causes and outcomes of burn in patients referred to shahid mohammadi hospital in bandar abbass, southern iran, in which 212 burned patients were assessed from march 2007 to march 2008 .mean age of patients was 22.14 yr. heat contact was the main cause of burn with 92.5%. 49.1% of total burns occurred among less than 20 yr old people. mortality rate was ...

PURPOSE To determine in a corneal alkaline burn model of angiogenesis whether the expression of integrins and MMPs is consistent with a VEGF-induced angiogenic response. METHODS Neovascularization in female Sprague-Dawley rats was induced by alkaline cauterization of the central cornea. RT-PCR for integrins alpha(1), alpha(2), beta(3), and beta(5); the endothelial marker CD31; and metalloprot...
