purpose: to report the outcomes of graft refractive surgery (grs) together with clear-cornea phacoemulsification and intraocular lens (iol) implantation in post-penetrating keratoplasty (pkp) eyes. methods: fourteen eyes of 13 patients who had received pkp underwent simultaneous grs (relaxing incisions with or without counter-quadrant compression sutures) and clear-cornea phacoemulsification wi...

a 37 - year- old man came to the hospital with a history of penetrating thoracoabdominal trauma due to gunshot wound in 10 days before. he underwent laparatomy and hepatorrhaphy in that time and right sided chest tube was inserted. chest ct scan revealed metallic foreign body in lung tissue due to bullet burst. right thoracotomy was performed and metallic foreign body extracted from lung tissue

PURPOSE In this study, we assessed the outcome of penetrating keratoplasties using organ-cultured corneal tissues at the University Eye Hospital, Ludwig-Maximilians-University, Munich, Germany. The goal was to identify perioperative and postoperative risk factors that may affect graft survival. PATIENTS AND METHODS The medical records of 377 patients who underwent a penetrating keratoplasty b...

INTRODUCTION Penetrating oesophageal injuries are extremely rare. Their timely recognition can be difficult and optimal treatment remains controversial. Early recognition of injury is possible with the help of a high index of suspicion and early radiological and endoscopic examinations. Prompt surgical intervention with primary repair of injury, should be the goal. PRESENTATION OF CASES We de...

In the framework of development green analytical chemistry, a silica gel (SG) coated with semi-penetrating network based on partially biosourced poly(ethersulfone) is studied for greener extraction process aromatic organic pollutants. An optimized composition (80% linear polymer (LP): isosorbide-based and 20% cross-linking agent (XP) type bismaleimide) leads to total adsorption selected polluta...

BACKGROUND Placebo needles that can mask acupuncture practitioners to the type of needle used have been considered almost impossible to develop until now. METHODS We designed a double-blind non-penetrating placebo needle, the needle tip of which simply presses against the skin, and a matched penetrating needle. The needles are encased inside an opaque guide tube and the appearance and feel of...

this is an observational case series study on penetrating trauma admissions in three teaching hospitals in tehran from 1996 to 1997. in order to describe the epidemiology and determine the ways of improving treatment of penetrating injuries, we selected 410 patients with penetrating injuries and injury severity scores (iss) of more than 7 (the maximum iss is 75) out of 3580 trauma patients, hos...

ocular trauma is an important cause of ocular morbidity in children. at present only limited studies regarding distribution of ocular trauma exist in iran. this study was performed to define epidemiologic characteristics and clinical profile of ocular trauma in children and to discuss management and final outcomes of such injuries. the files of 60 patients aged 16 years or younger who had been ...

BACKGROUND US combat operations in Iraq and Afghanistan have resulted in a greater proportion of service members with head and neck wounds caused by explosions compared with that of previous wars. Although penetrating traumatic brain injury (TBI) is frequently associated with these wounds, the epidemiology of penetrating TBI from these conflicts has not been well described. METHODS The Joint ...

Abstract Understanding the internal structure of specific landforms is a crucial prerequisite for determining their origin and evolution. Near-surface geophysics represents non-invasive way subsurface investigation, it can be used to describe conditions, especially in protected areas. We tested possible hypotheses block accumulations evolution by four different geophysical methods (electrical r...
