 Materials methods. The included 78 patients with diagnosis combined trauma, including penetrating/non-penetrating wound or injuries. media...

Penetrating craniofacial traumas are rarely seen in childhood, but can lead to serious morbidities or mortality associated with the injuries of vital neurovascular structures.1 Penetrating craniofacial injuries in childhood are most commonly caused by knives and guns, or fragments of glass and metal.2,3 Penetrating injuries from screwdrivers and spear guns are rare among children and very few c...

PURPOSE To compare the measurement of contrast sensitivity at a distance in patients submitted to penetrating keratoplasty versus patients submitted to deep anterior lamellar keratoplasty for keratoconus treatment. METHODS Contrast sensitivity of fourteen subjects submitted to penetrating keratoplasty and fourteen subjects submitted to deep anterior lamellar keratoplasty have been analyzed th...

The field of gene therapy is starting to move towards clinical applications but is currently limited by the lack of efficient delivery systems. Cell-penetrating peptides provide a means of cellular delivery for gene therapy applications as well as delivery of traditional drugs. Using cell-penetrating peptides a range of different cargoes have been successfully delivered into a number of cell ty...

PURPOSE To report a case of Candida keratitis following penetrating keratoplasty in a patient with Candidiasis of the fingernails. CASE REPORT An 80 year-old male presented with recurrent Candida keratitis following penetrating keratoplasty. Patient was found to have evidence of Candidiasis of the fingernails. COMMENT Candidiasis of the fingernails have led to recurrent fungal keratitis fol...

This paper presents analytical solutions and simulations for pressure transient behavior of the partially penetrating wells (PPWs). The Newman’s product method was adopted to develop the basic instantaneous source functions which characterize the response of PPWs. These results were obtained based on the solution of fully penetrating wells (FPWs) and they were presented in Laplace domain. Furth...

Penetrating scrotal trauma is an uncommon injury that is often secondary to civilian or combat violence. Much of the literature on the topic is from case reports, small retrospective series from civilian trauma centers, and reports from combat zones. In this manuscript, a case report involving self-inflicted penetrating scrotal trauma from our institution is presented. Following the case report...
