1/9. Death due to attack from chow dog.It is estimated that between one and four million persons per year are bitten by dogs in the united states. While most injuries associated with the bites are minor, serious sequelae, and even death, may occur. Most victims of fatal dog attacks are children < 1 year of age or elderly women. The most frequent cause of death is hemorrhage and shock from major vessel damage. A case is reported in which an elderly woman was attacked by her pet Chow dog. The victim received multiple superficial abrasions, contusions, and lacerations from the dog attack. A large perforation of the right external pudendal vein and three perforations of the left superficial femoral vein resulted in exsanguination and death. Fractures of the left 2nd through 4th ribs with underlying pulmonary contusion were also found.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/9. radial artery injury from a catfish sting.We present a case of an isolated radial artery laceration injury secondary to a catfish sting. Six months after surgical removal of the cartilaginous spine and primary repair of the vessel wall, the patient had an uneventful follow-up with minimal symptoms of cold intolerance and maintained arterial patency as documented by Allen's test and ultrasound.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/9. Acute myocardial infarction associated with DF-2 bacteremia after a dog bite.This is the first reported case of an acute myocardial infarction probably secondary to DF-2 bacterial septicemia and presumed endocarditis. Selective coronary arteriography revealed a long filling defect causing 95% stenosis of the second diagonal branch of the left anterior descending coronary artery. Multiple blood cultures revealed Decarboxylase Fermentor-2 (DF-2) septicemia that responded to penicillin therapy. Two months status after myocardial infarction recatheterization revealed complete recanalization with slight irregularity of the vessel lumen at the site of previous obstruction.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/9. An unusual form of motor neuron disease following a cat bite.A case of motor neuron disease with clinical and pathological resemblance to amyotrophic lateral sclerosis (ALS) in a woman who was severely bitten on the ankle by a cat is described. Weakness first appeared at the ankles and relentlessly advanced proximally, terminating in death from pulmonary failure in a year. A number of unusual features that are uncharacteristic of ALS were found that included a markedly elevated antinuclear antibody titre in the serum and the presence of prominent oligoclonal bands in the cerebrospinal fluid. The spinal cord showed loss of anterior horn cells and pyramidal degeneration that are characteristic of ALS, but an extraordinary finding was the presence of transmural granulomatous inflammation of numerous small and medium sized vessels, especially veins, in the subarachnoid space around the cord. There were also inflammatory changes in the brainstem and spinal cord consisting of microglial and astrocytic nodules and perivenous cuffing by mononuclear cells. Ill-defined hyaline eosinophilic cytoplasmic inclusions were seen in some remaining anterior horn cells. No viral particles were found by electron microscopy despite an extensive search. Virological studies were inconclusive but there is reason to believe that this patient's illness was caused by an as yet unidentified virus.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/9. Delayed cerebral infarction after dog bites: case report.Delayed cerebral infarction occurred after dog bites in the region of the internal carotid artery of a 7-year-old boy. Initial wound exploration and repair did not reveal any signs of vascular trauma. Understanding the dynamics of the bites and relating the wounds topographically to the course of the underlying large vessels are key factors in early diagnosis of occult vascular damage.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/9. Peripheral neuropathies after arthropod stings not due to lyme disease: a report of five cases and review of the literature.Five patients developed neurologic symptoms a few hours to 2 months after being stung by a non-hooking arthropod with immediate cutaneous reaction. The patients had no clinical or serologic evidence for Lyme borreliosis and rickettsial disease. Clinical and electrophysiologic findings were consistent with a mixed axonal and demyelinating mononeuropathy, a monomelic multiple mononeuropathy, a mononeuropathy multiplex, a radiculoneuritis, and a distal symmetric polyneuropathy. Muscle and nerve biopsies showed lymphoplasmacytic small-vessel vasculitis in all patients, and wallerian degeneration in three. These patients, and 17 others from the literature, indicate a spectrum of peripheral neuropathies occurring after insect and spider stings.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/9. stroke following rottweiler attack.A previously healthy 50-year-old man suffered a major right cerebral infarction shortly after receiving head and neck bites in an attack by two rottweilers. Arteriography revealed occlusion of the right middle cerebral artery, an intimal flap and pseudoaneurysm in the high right internal carotid artery just proximal to the skull base, and an obstructed right vertebral artery. The powerful jaw mechanism of rottweilers and other large mastiff-type dogs makes their bites particularly destructive. The predilection of these animals for attacking the head and upper body makes occult crush injury to the extracranial cerebral vessels an important diagnostic consideration following such attacks.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
8/9. Managing law enforcement (K-9) dog bites in the emergency department.OBJECTIVE: To review the types of injuries due to law enforcement (K-9) dog bites and address related management issues. methods: A case series of law enforcement dog bite victims is reported and related literature reviewed. RESULTS: law enforcement dogs are taught a bite-and-hold technique for subduing individuals suspected of felony crimes. This bite-and-hold technique's greater applied force results in a unique spectrum of injuries, including deep puncture wounds, severe crush injuries, large tissue avulsions and lacerations, wounds necessitating surgical debridement, bony injuries ranging from cortical violations to displaced fractures, neurovascular damage, and other wounds at high risk for infection. The four reported cases highlight the types of injuries and complications associated with law enforcement dog bites. CONCLUSION: attention to potential deep injuries of nerves, vessels, and the musculoskeletal system is essential with law enforcement dog bites. Injuries associated both with pursuit and arrest and with the bites themselves must be identified and assessed. Guidelines for the ED treatment of patients with law enforcement dog bite injuries are proposed.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
9/9. Successful hand revascularization with urokinase following a crush injury.Acute hand ischemia is a medical emergency requiring immediate treatment. We report a case of acute hand ischemia due to a crush injury of the wrist. Management with urokinase was successful in reestablishing flow to the ulnar artery and the digital vessels. In the setting of acute trauma with extensive thrombosis of the vessels of the hand, thrombolytic therapy may offer a better treatment option than surgical exploration with bypass grafting.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
