1/9. Induced hypothermia: electrocardiographic abnormalities.hypothermia was induced intermittently in a patient to combat hyperpyrexia. The electrocardiogram taken during the hypothermic phase displayed typical abnormalities and consisted of: pronounced sinus bradycardia, marked prolongation of the Q-T interval, muscle tremor artifact, and the characteristic "Osborn wave." Spontaneous rewarming resulted in disappearance of the electrocardiographic alterations, underscoring the functional and reversible nature of the abnormalities.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
2/9. death due to concussion and alcohol.We encountered 5 deaths following blunt trauma to the face and head in which the injuries were predominantly soft tissue in nature with absence of skull fractures, intracranial bleeding, or detectable injury to the brain. All individuals were intoxicated, with blood ethanol levels ranging from 0.22 to 0.33 g/dl. We feel that in these deaths, ethanol augmentation of the effects of concussive brain injury, with resultant posttraumatic apnea, was the mechanism of death.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
3/9. absidia posttraumatic infection: successful treatment with posaconazole.The class zygomycetes is a large group of filamentous fungi found ubiquitously in nature, primarily in humid soil. Their virulence in immunocompetent hosts is low; therefore, they are usually considered to be contaminants of cultures. In the present study, we describe a patient who had severe traumatic injury with an absidia infection, who developed intolerance to antifungal treatment with amphotericin b, but responded to posaconazole treatment.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
4/9. disseminated intravascular coagulation and facial injury.A severe case of disseminated intravascular coagulation secondary to a road traffic accident in a pregnant woman is presented. The nature of this recognised complication of pregnancy is noted, and the problems encountered when it occurs together with facial trauma, are described. The importance of awareness and recognition of this condition is emphasised.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
5/9. salmonella typhi facial infection. Report of case.The following case report describes the evaluation, assessment, and treatment of a facial infection due to salmonella typhi, caused by bites from the family's pet dog. The causative agent and the mode of transmission are unique in that there are no reported cases of this nature in the literature at this time.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
6/9. Trigeminal neurapraxia following a blow to the face: a case report.Examination of the cranial nerves is a simple and valuable procedure following trauma to the head and neck. By understanding their courses, branches and distributions, the site of any damage may be localized. Once the site and nature of injury has been determined, correct management may be instigated. A case is presented in which there was some degree of trigeminal nerve damage following trauma. The site of damage was determined to be extracranial and therefore a conservative regimen adopted. The mechanism of injury is postulated.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
7/9. Craniofacial injuries resulting from taxicab accidents in new york city.Taxicab accidents are a common occurrence in new york city. This review was undertaken to characterize the nature of craniofacial injuries that result from taxicab accidents. Data were collected on 16 patients who required admission to trauma or plastic and reconstructive surgery services, after sustaining craniofacial injury as a result of a taxicab accident. Front-end deceleration collisions were the most common mechanism of injury. Fifty-six percent of the patients were thrown against the bulletproof, Plexiglas driver safety divider and sustained an injury most commonly to the anterior midface. Both bony and soft-tissue injuries were common in the entire group. Complex facial fractures were sustained by 56% of patients, with nasal-septal fractures most common, followed by naso-ethmoid-orbital, anterior frontal, anterior maxillary, and Le Fort I and II fractures. Only 1 patient in the group was wearing a seat belt and that patient was a driver. Given the high incidence of craniofacial injury, appropriate safety standards for taxicabs must be initiated, including the reevaluation of the utility of the safety divider and mandatory seat belt use for rear-seat passengers.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
8/9. epistaxis originating from traumatic pseudoaneurysm of the internal carotid artery: diagnosis and endovascular therapy.Posttraumatic pseudoaneurysm of the internal carotid artery (ICA) is an uncommon but potentially fatal cause of epistaxis. Because the onset of delayed bleeding from the time of injury is variable, prompt diagnosis of cavernous ICA pseudoaneurysm is often a clinical challenge. The relative urgency to evaluate for this disease is highlighted by the morbid nature of this entity. Optimal management demands rapid recognition and treatment to give the best functional outcome. The authors present a case series of six patients with skull base ICA pseudoaneurysm. A unifying feature in the majority of patients is the development of delayed, massive epistaxis. The time course for presentation of delayed life-threatening epistaxis ranged from 5 days to 9 weeks. Two patients exhibited the classic triad of unilateral blindness, orbital fractures, and massive epistaxis. All patients requiring intervention were successfully treated with endovascular embolization techniques that included detachable balloons and coils. The clinical and radiologic findings in this case series are presented. The relevant anatomy, diagnosis, and treatment of traumatic ICA pseudoaneurysm are reviewed. A contemporary treatment strategy is proposed.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
9/9. The use of high-density polyethylene implants in facial deformities.OBJECTIVE: To determine the usefulness of porous high-density polyethylene implants (Medpor) in a variety of facial skeletal deformities and subcutaneous defects, excluding those associated with acute maxillofacial trauma. DESIGN: Case series. SETTING: Academic tertiary care referral center in baltimore, Md. patients: Thirty-four patients (age range, 20-74 years) with facial deformities requiring skeletal defect reconstruction or augmentation (38 cases), treated between January 1, 1992, and January 1, 1997. Follow-up ranged from 6 months to 40 months. MAIN OUTCOME MEASURES: Age, type and origin of the deformity treated, type of treatment, and complications. RESULTS: Types of deformities and defects treated include 7 patients with orbital defects (secondary traumatic or oncologic deformities), 8 with temporal fossa defects, 8 with frontocranial defects, 4 with maxillary or malar defects, 7 with calvarial bone graft donor site defects, 2 with microtia, and 2 with chin deficiency. Forty implants were placed. Complications included implant exposure in 4 patients and inappropriate augmentation in 1 patient (chin implantation). CONCLUSIONS: High-density polyethylene implants offer an excellent alternative to autogenous and other alloplastic materials in reconstruction of many facial defects and deformities. Advantages include its versatility and relatively ideal pore size that allows for excellent soft tissue ingrowth and coverage. Disadvantages include its rigid nature and difficulty in contouring to the surface of complex skeletal structures.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
