Objective. To determine if a single mailing from the local volunteer fire department can increase the number of homes with proper, visible address numbering. Proper numbering is essential in rapidly locating a house during an emergency response. Methods. The study was conducted at a suburban/rural fire department providing EMS andfire suppression services to a 22 square mile area with residential mailboxes located at the street. During a hazard identification pre-plan tour, each house was examined andassigned a classification: (A) No number visible on the house or mailbox (improper); (B) Number on only one side of the mailbox (improper); (C) Number on both sides or the end of the mailbox, or visible on the house (proper). The homeowners of all residences with improper numbering (A or B) were sent a one-page letter, discussing the need for proper numbering. The tour was repeated six weeks later to determine whether deficiencies had been corrected. It was prospectively determined that a 25% improvement was sought. Results. During the pre-plan tour, 73 houses were classified as type A, 454 as type B, and1706 as type C. At the re-visit, 135 (26%) of the type A andB homes had been properly numbered. Correction of deficiencies was better at type A homes (37, or 51%) than at type B homes (98, or 22%) (p < 0.001 by Chi-square). Conclusion. For houses with improper numbering, a single mailing from the fire department can be effective in encouraging residents to post proper numbers. 相似文献

Twelve patients with 15 separate, spontaneously hemorrhagic, intracranial malignant lesions (seven primary gliomas, eight metastatic lesions) were examined with spin-echo magnetic resonance imaging at 1.5 T, and with computed tomography. The signal intensity patterns of these lesions, as seen on both short repetition time (TR)/short echo time (TE) and long-TR/long-TE spin-echo pulse sequences, were compared with the previously described appearance at 1.5 T of non-neoplastic intracerebral hematomas. The images of hemorrhagic intracranial malignancies showed notable signal heterogeneity, often with identifiable nonhemorrhagic tissue corresponding to tumor; diminished, irregular, or absent hemosiderin deposition; delayed hematoma evolution; and pronounced or persistent edema, compared with non-neoplastic hematomas. The demonstration of these characteristics in the appropriate clinical setting may suggest malignancy as the cause of an intracranial hematoma. 相似文献
