Case summary: A 4-year-old female spayed, indoor/outdoor domestic mediumhair cat presented with multiple bleeding puncture wounds and hemorrhagic shock. The cat was diagnosed with suspected pit viper envenomation based on the location and appearance of the bite wounds, as well as the presence of severe coagulopathy with prolonged activated coagulation time (762 s), which responded to antivenom administration. The clinical course of the cat was unique owing to the prolonged clinical signs of envenomation that appeared as intermittent coagulopathy and hemorrhage over a 2 week period...

Efforts to develop tissue-engineered skin for regenerative medicine have explored natural, synthetic, and hybrid hydrogels. The creation of a bilayer material, with the stratification exhibited by native skin, is a complex problem. The mechanically robust, waterproof epidermis presents the stratum corneum at the tissue/air interface, which confers many of these protective properties. In this work, we explore the effect of high temperatures on alginate hydrogels, which are widely employed for tissue engineering due to their excellent mechanical properties and cellular compatibility...

Arteriovenous malformations (AVMs) are rare congenital vascular malformations accounting only 1.5% of all vascular anomalies with 50% occurrence in the oral and maxillofacial region. It usually results from birth defects of the vasculature. A literature search revealed only few case reports of AVMs in the facial region. Lack of meticulous diagnosis, scarcity of knowledge, and paucity of literature can result in their exsanguinations leading to fatal hemorrhagic incidents after various dental procedures such as tooth extraction, surgical intervention, puncture wound, or blunt injury in involved area...

BACKGROUND: Puncture wounds in the 1-mm range usually heal without scars. Stacking rows of these punctures offers a scarless method to generate tissue by mesh expansion. We developed a percutaneous mesh expansion (PME) procedure and present our experience for its wound closure application. METHODS: Over a six-year period we applied PME to 65 consecutive patients 58-101 years-old (mean, 72) with 67 full thickness calvarial defects 2.5x3-7x8cm (mean, 14cm2) that would have all required flaps for closure...

INTRODUCTION: Fingertip amputation injuries are common in all ages. Conservatively treated fingertips can regenerate skin and soft tissues to form a functionally and cosmetically excellent new fingertip. Little is known about this ability that, in humans, is confined to the fingertips. Even less is known about the role of the bacteria that regularly colonize these wounds without negative impact on regeneration and healing.As an alternative to surgery, self-adhesive film dressings are commonly used to establish a wet chamber around the injury...

BACKGROUND: Thoracic trauma represents 5% of all battlefield injuries. Communicating pneumothoraces resulting in tension physiology remain an important etiology of prehospital mortality. In addressing penetrating chest trauma, current Tactical Combat Casualty Care (TCCC) guidelines advocate the immediate placement of a vented chest seal device. Although the Committee on TCCC (CoTCCC) has approved numerous chest seal devices for battlefield use, few data exist regarding their use in a combat zone setting...

Pyogenic flexor tenosynovitis (PFT) is a well known infectious condition of the hand, involving the inoculation of the flexor tendon sheath with microorganisms. Many cases have been reported, common causes including direct inoculation by a puncture wound and deep lacerations extending into the flexor tendon sheath. In this report, we present a case of a 50 year old female with PFT resulting from autophagia (consuming one's own body parts, in our case, fingers) successfully treated with irrigation and debridement, amputation of the index finger at the metacarpophalangeal joint and antibiotic therapy...

We present the case of a 91-year-old woman lived alone at her home with two domestic dogs, that is,, a Labrador Retriever and a Staffordshire Bull Terrier and found dead. The investigation of the scene revealed that the Bull Terrier's jawbone and chest were covered with blood. The autopsy revealed multiple, histologically confirmed, life-threatening skin and bone lacerations without scavenging marks. The punctures and tearing of each of the wounds on the skin were compatible with bites. A left humeral fracture and multiple fractures of the right facial bones were observed...

Back pain is a major health problem. The degenerative cascade of the spine begins in the intervertebral disc, due to an impairment in the blood supply through the vertebral endplates. Our objective was to develop a novel disc degeneration model based on these premises, akin to the process in humans, in contrast to other proposed models (puncture, enzyme injection, aberrant loads,…) Material and methods: 37 Sprague-Dawley rats, 2 arms: (a) histological (n = 17, one died), en- bloc sections, Van Gieson staining, (Nisimura-Mochida criteria) and also collagen VI staining (tissue oxidative stress), four animals were euthanized every 2 weeks (2-8); and (b) imaging (n = 20, six wound sloughs), MRI 9...

OBJECTIVES: Snakebite severity corresponds to size of snake because the amount of venom a snake injects is positively associated with snake size. Because fang marks are often present on snakebite patients, we tested whether the relationship between snake length and distance between fang puncture wounds can be generalized for rattlesnakes of genus Crotalus. METHODS: We measured 2 interfang distances from 79 rattlesnakes of both sexes, 5 species, and varying body length: 1) distance between fang bases in anesthetized snakes, and 2) distance between fang punctures in a membrane-covered beaker bitten defensively...

The aim of the present study was to determine the effectiveness of nonsurgical treatment for osteomyelitis of the hallucal sesamoids. Osteomyelitis of the hallucal sesamoids in young and healthy patients is rare and might originate from hematogenous spread or after a puncture wound. In diabetic patients with peripheral neuropathy, it often results from direct contiguous seeding from adjacent ulceration. The superiority of surgical versus nonsurgical therapy is still debated. In our institution, all patients presenting with osteomyelitis of the hallucal sesamoids are first treated nonsurgically but eventually usually require a surgical procedure...
