The aim of the present study is to determine the best size and type of corneal graft (lamellar or penetrating, as judged by the incidence of postoperative complications) for use in cases of central or peripheral leucoma adherens measuring 4-5 mm. or less. Penetrating grafts smaller than 4 mm. rarely remain transparent and those above 7 mm. also often become opaque and may be complicated by glau...

Penetrating injury of the skull and brain are relatively uncommon events, representing about 0.4% of all head injuries. Transorbital penetrating brain injury is an unusual occurrence in emergency practice and presents with controversial management. We report the case of a 10-year-old boy who fell forward on a bamboo stick while playing with other children, causing a penetrating transorbital inj...

Penetrating landmine injuries are the unavoidable consequences of military conflicts. They are potentially life-threatening. The mortality rates in the literature range from 23% to 92% and are considerably higher in patients admitted with poor neurologic state. Penetrating craniocerebral injuries require early surgical management designated to prevent infection and remove foreign objects, necro...

Penetrating neck injuries by traditional weapons are rare entity in the modern era of sophisticated weapons. We report an unusual case of penetrating neck injury by a metallic arrow entering anterior neck in zone II and its tip coming out of neck posteriorly causing difficulty for patient to lie down as well as posing challenge to intubate. Arrows are low velocity projectile and from a close pr...

INTRODUCTION Penetrating thoracoabdominal injuries are potentially life threatening due to the associated hemorrhagic shock and visceral injury. Through and through penetrating injury with polytrauma is rarely encountered. CASE PRESENTATION Here we report on a 25-year-old male with penetrating thoracoabdominal injury caused by a metallic (iron) bar projecting from a pillar of a construction s...

A hydrogen peroxide (H2O2)-activated cell-penetrating peptide was developed through incorporation of a boronic acid-containing cleavable linker between polycationic cell-penetrating peptide and polyanionic fragments. Fluorescence labeling of the two ends of the molecule enabled monitoring its reaction with H2O2 through release of the highly adhesive cell-penetrating peptide and disruption of fl...

Penetrating keratoplasty is the replacement of a diseased cornea with a full-thickness donor graft. In the last century, this 'gold standard' procedure was long established as the treatment of choice for various corneal diseases. The classical indications for a penetrating keratoplasty entailed optical, tectonic, therapeutic, and cosmetic issues. Over the past decade however, surgical advances ...

Nonmissile penetrating brain injuries are exceedingly uncommon among civilian population and are most often associated with inflicted injury. They show specific characteristics different from that of missile wounds. In this article, we describe a rare case of a 22-month-old child who experienced accidental penetrating head trauma caused by a crossbow. We document neuroimaging studies and review...

The leading causes of trauma to the major craniocerebral vessels include penetrating and non penetrating trauma [1 , 2]. Because the vertebral artery is confined to the incomplete bony canal formed by the successive foramina in the transverse processes of the upper cervical vertebrae, it is less susceptible to penetrating injury than is the carotid artery [2]. A review of the literature has unc...

OBJECTIVES To share results and recommendations for management of penetrating cochlear injury. METHODS A patient underwent repair of a penetrating cochlear injury after a projectile led to a traumatic cochleostomy with a narrow miss of the facial nerve and intracranial carotid artery. RESULTS Postoperatively, the patient's audiogram demonstrated a pure tone average of 47.5 dB for air conduc...
