Overcrowded motor vehicle trauma from the smuggling of illegal immigrants in the desert of the Southwest 总被引:1,自引:0,他引:1
Overcrowded motor vehicle crashes caused by the very active criminal enterprise of smuggling illegal immigrants in the desert of the Southwest is a recent and under-recognized trauma etiology. A computerized database search from 1990 through 2003 of local newspaper reports of overcrowded motor vehicle crashes along the 281 miles of Arizona's border with Mexico was conducted. This area was covered by two level I trauma centers, but since July 2003 is now served only by the University Medical Center. Each of these crashes involved a single motor vehicle in poor mechanical shape packed with illegal immigrants. Speeding out of control on bad tires, high-speed rollovers result in ejection of most passengers. Since 1999, there have been 38 crashes involving 663 passengers (an average of 17 per vehicle) with an injury rate of 49 per cent and a mortality rate of 9 per cent. This relatively recent phenomenon (no reports from before 1998) of trauma resulting from human smuggling is lethal and demonstrates the smugglers' wanton disregard for human life, particularly when facing apprehension. Even a few innocent bystanders have been killed. These crashes overwhelm a region's trauma resources and must be recognized when planning the distribution of trauma resources to border states. 相似文献

Emery-Dreifuss muscular dystrophy is a rare disorder characterized by childhood onset of contractures, humeroperoneal muscle atrophy, and cardiac conduction abnormalities. This report presents the cases of two brothers with this dystrophy in whom bilateral hypomyelination of the deep periatrial white matter was noted. In the hypomyelinated regions, a prominent peak centered at 1.5 parts per million was present on short-TE MR spectra likely representing prominence of proteolipids in the macromolecular region. Major peaks (N-acetyl-aspartate, creatine, choline, and myoinositol) were normal. With respect to muscle changes, atrophy of the medial head of the gastrocnemius muscle was noted at MR imaging, and phosphorus spectroscopy of this muscle revealed decreased phosphocreatine and inorganic phosphate peaks. 相似文献

Compliance with protocols in transferring emergency patients to a tertiary care centre 总被引:1,自引:0,他引:1
STUDY OBJECTIVES: We evaluated compliance with standard patient transfer protocols in a pre- and post-interventional study among patients transferred from other hospitals to our tertiary care university hospital. METHODS: In the first phase, transfer information was recorded on the arrival in 174 consecutive patients transferred to our emergency department (ED) over a 2-month period in 1999. Emergency caregivers throughout the province then received education about proper transfer procedures. This training was provided through monthly citywide co-ordination and co-operation meetings among the physicians of the emergency medical services (EMS) and the emergency departments of the hospitals in the city and the nearby counties. Fifteen months after the beginning of these educational efforts, the second observational phase was implemented. Over a period of 2 months in early 2001, information was recorded from 180 consecutive patients transferred to our ED. Presence of patient medical records, laboratory results, and X-rays; clearly delineated reason for transfer; prior notification of transfer; and appropriate care during transport from the initial facility were the parameters compared in the pre- and post-intervention periods. RESULTS: Patients in phase-II were found to have had more appropriate care in some respects, such as presence of cervical collar and proper airway management, during transport from the initial facility than patients in phase-I (P < 0.05). However, other parameters were not significantly different between the two phases. CONCLUSION: We have concluded that our monthly meetings and conferences have made a positive impact on compliance with some of the standard transfer protocols. We must however, continue our efforts to increase compliance with other aspects of standard patient transfer guidelines. 相似文献

OBJECTIVES: Peer review of trauma deaths can be used to evaluate the efficacy of trauma systems. The objective of this study was to estimate teh proportion of preventable trauma deaths and the factors contributing to poor outcome using peer review in a tertiary care hospital in a developing country. METHODS: All trauma deaths during a 2-year period (1 January 1998 to 30 December 1998) were identified and registered in a computerized trauma registry, and the probability of survival was calculated for all patients. Summary data, including registry information and details of prehospital, emergency room, and definitive care, were provided to all members of the peer review committee 1 week before the committee meeting. The committee then reviewed all cases and classified each death as preventable, potentially preventable, or non-preventable. RESULTS AND CONCLUSION: A total fo 279 patients were registered in the trauma registry during the study period, including 18 trauma deaths. Peer review judged that six were preventable, seven were potentially preventable, and four were non-preventable. One patient was excluded because the record was not available for review. The proportion of preventable and potentially preventable deaths was significantly higher in our study than from developed countries. Of the multiple contributing factors identified, the most important were inadequate prehospital transfer, limited hospital resources, and an absence of integrated and organized trauma care. This study summarizes the challenges faced in trauma care in a developing country. 相似文献

Infantile fibromatosis is an uncommon, usually cutaneous, nonmetastasizing but locally aggressive fibroblastic proliferation. Involvement of the sinonasal area is extremely uncommon, and only 5 cases have been previously reported. We report a new case, which occurred in a 2-year-old boy. The mass involved the nasal cavity and the paranasal sinuses and extended into the cranial cavity. We also discuss the clinicopathologic features of this lesion, including its ultrastructural characteristics, and we review the literature. 相似文献

From a histopathologic perspective, head and neck squamous cell carcinoma (HNSCC) is a relatively straightforward diagnosis. However, the clinically useful information presently provided by pathologists is embarrassingly limited. Similarly, our ability to accurately identify the earliest premalignant lesions as well as predict which premalignant lesions are likely to progress to HNSCC is limited. Over the last decade, an explosive growth of knowledge related to the molecular biology of this disease has occurred, which is now being used to address these issues. For example, we now appreciate that there are multiple etiologies and multiple molecular mechanisms responsible for the development of HNSCC. New techniques have improved our ability to identify molecularly premalignant, but histologically benign lesions. Similarly, recent studies have been able to predict which premalignant lesions are likely to progress to HNSCC. In addition to having utility in the realm of early diagnosis, molecular diagnostics may have a profound impact on how we diagnose and report HNSCC. While still in the developmental stage, molecular protocols are being used to evaluate surgical margins, determine the location of unknown primary tumors, identify histologically undetectable lymph node metastasis, and predict which tumors are more likely to respond to a particular postsurgical adjuvant therapy. 相似文献

Cervico-oculo-acoustic (COA) or Wildervanck syndrome is characterized by the triad of Klippel-Feil anomaly, bilateral abducens palsy with retracted bulbs (Duane 'syndrome') and hearing loss. The clinical findings of this syndrome have been well documented. A few case reports with MRI findings have appeared in the literature showing brainstem and cerebellar hypoplasia and vertebral segmentation anomalies. Our case is unique in that diastematomyelia of the lower medulla and cervical cord was accompanied by vermian hypoplasia, tonsillar herniation and resulting triventricular hydrocephalus in a child with Wildervanck syndrome. This case is presented with MR images. Children with Wildervanck syndrome should be investigated for craniospinal abnormalities with MR imaging. 相似文献
