Leishmania parasites are transmitted to vertebrate hosts by female phlebotomine sand flies as they bloodfeed by lacerating the upper capillaries of the dermis with their barbed mouthparts. In the sand fly midgut secreted proteophosphoglycans from Leishmania form a biological plug known as the promastigote secretory gel (PSG), which blocks the gut and facilitates the regurgitation of infective parasites. The interaction between the wound created by the sand fly bite and PSG is not known. Here we nanoinjected a sand fly egested dose of PSG into BALB/c mouse skin that lead to the differential expression of 7,907 transcripts...

The stink bug Dichelops furcatus (F.) (Heteroptera: Pentatomidae) has increased in abundance in recent years on the wheat, Triticum aestivum L., crop cultivated in the southern region of Brazil. To investigate the probing (stylet penetration) behaviors and nonprobing behaviors of D. furcatus on wheat plants, the electrical penetration graph or electropenetrography (EPG) technique was applied. Nine EPG waveforms (types/subtypes) were identified and described on stem and on ear head of wheat plants, as follows: Z, Np, Df1a, Df1b, Df2, Df3a, Df3b, Df4a, and Df4b...

The goals of laceration repair are to achieve hemostasis and optimal cosmetic results without increasing the risk of infection. Many aspects of laceration repair have not changed over the years, but there is evidence to support some updates to standard management. Studies have been unable to define a "golden period" for which a wound can safely be repaired without increasing risk of infection. Depending on the type of wound, it may be reasonable to close even 18 or more hours after injury. The use of nonsterile gloves during laceration repair does not increase the risk of wound infection compared with sterile gloves...

In cases of head trauma, the ear should be evaluated in all of its components. A good understanding of otologic and skull base anatomy enables a thorough trauma assessment of this complex anatomic region. Auricular laceration, abrasion, avulsion, hematoma, frostbite, otitis externa, exostosis, tympanic membrane perforation, ossicular discontinuity, perilymphatic fistula, labyrinthine concussion, temporal bone fracture, facial nerve paresis, and sensorineural hearing loss are a few of the more common otologic injuries seen in active patients...

A previously healthy 65-year-old female passenger presented on the 3rd day of her voyage with a small facial laceration after she fell and hit her forehead, following sudden blurred vision and dizziness. When the ship's doctor noticed that one pupil was much bigger than the other, he feared intracranial bleeding and considered helicopter evacuation. Her symptoms had started shortly after she had removed a transdermal scopolamine patch from behind her ear. Getting scopolamine from her hands in direct contact with the eye surface caused mydriasis...

BACKGROUND: Child maltreatment is persistently under-recognised. Given that a third of maltreated children may return with serious or fatal injuries, it is imperative that otolaryngologists who are in frequent contact with children are able to detect maltreatment at first presentation. OBJECTIVE OF REVIEW: This review aims to identify ENT injuries, signs or symptoms that are indicative of physical abuse or fabricated or induced illness (child maltreatment). TYPE OF REVIEW: Systematic review...

BACKGROUND: Adequate emergency department (ED) anesthesia for painful ear conditions, such as ear lacerations or ear abscesses, can be challenging. Much of the sensory innervation of the ear is supplied from the anterior and posterior branches of the greater auricular nerve (GAN). The GAN is a branch of the superficial cervical plexus, which arises from the C2/C3 spinal roots. The GAN innervation includes most of the helix, antihelix, the lobule, and the skin over the mastoid process and parotid gland...

BACKGROUND: Many trauma patients in the Emergency Department are unconscious, and this causes many other problems to go undiagnosed, resulting in the loss of valuable time in initiating the appropriate treatments. The purpose of this study was to determine the prevalence and types of injuries to the ears, nose, and throat that are ignored in patients with multiple traumas in an Emergency Department. METHODS: This study was conducted by assessing patients with multiple traumas who were admitted to the Emergency Department at Shahid Rahnamun Hospital in Yazd, Iran, in 2012 and 2013, and who were advised to acquire diagnostic workups and treatment in the Ear, Nose, and Throat Department...

Smaller injuries of the auricle, such as lacerations without tissue loss, have more or less standardized treatment protocols that require thorough wound closure of each affected layer. Even extended lacerations of larger parts of the ear quite often heal with only minor irregularities. New in vivo diagnostic tools have aided the understanding of this outstanding "skin flap behavior." At the other end of the trauma severity spectrum are partial or complete amputations of the ear. Here, the debate has become more intense over the last decade...

UNLABELLED: Impalement injuries in children may be deeper and more complicated than anticipated. We experienced two cases of accidental impalement injuries, one was through the oral cavity and the other was to the neck. We review these cases and the management of these types of injuries. CASE SERIES: In case 1, a 20-month-old girl fell from the table with a toothbrush in her mouth. She was conscious, without any apparent neurologic or vascular injuries. Examination revealed a 2 mm laceration with a small hematoma in the right posterior pharyngeal wall...

INTRODUCTION: Documentation and billing for laceration repair involves a description of wound length. We designed this study to test the hypothesis that emergency department (ED) personnel can accurately estimate wound lengths without the aid of a measuring device. METHODS: This was a single-center prospective observational study performed in an academic ED. Seven wounds of varying lengths were simulated by creating lacerations on purchased pigs' ears and feet. We asked healthcare providers, defined as nurses and physicians working in the ED, to estimate the length of each wound by visual inspection...

Facial palsy that occurs immediately after middle ear surgery (stapedectomy, stapedotomy, and tympanoplasty) can be a consequence of the local anesthetics and it regresses completely within a few hours. In the case of delayed facial palsy, the alarming symptom occurs several days or even weeks after uneventful surgery. The mechanism of the neural dysfunction is not readily defined. Surgical stress, intraoperative trauma, or laceration of the chorda tympani nerve with a resultant retrograde facial nerve edema can all be provoking etiological factors...

Correct treatment of traumatic facial lacerations is essential to achieve the best cosmetic and functional outcome. This article discusses wound management, anatomy and techniques to repair lacerations of scalp, eyelid, nose, lip and ear. Scalp lacerations should be sutured in layers. Injury to the eyelid mandates a careful examination of the eye. Accurate adaptation of the lid margin is required. Nasal septum haematoma must be drained and the nares and alar margins aligned. The key to proper repair of lip laceration is alignment of the vermillion border...

UNLABELLED: Traumatic cleft earlobe is the most common secondary deformity of the ear. Numerous techniques have been introduced to repair traumatic cleft earlobe and break the linear scar. However, most of the techniques require elevation of additional flaps from normal surrounding tissue and sacrifice healthy tissue from small earlobes. The authors used epithelialized scar tissue from the cleft margin to elevate 2 triangular flaps. The flaps were turned 90 degrees to fit into the fish-mouth incision at the margin of the cleft earlobe...
