BACKGROUND: Most febrile neutropenic patients are treated in an aggressive manner. However, identification of low-risk patients may enable clinicians to administer risk-based treatment. The object of this study is to certify the factors associated with increased risk at the time of visiting the emergency department. METHODS: This is a retrospective study. We reviewed the medical records of 101 febrile neutropenic patients who had visited the emergency department of Seoul National University Hospital from January 1998 to August 1999. We assumed 22 risk prediction factors that could be assessed at admission to the emergency department and 5 factors that could be assessed during treatment course. To find independent risk-prediction factors, we analyzed these factors respectively by using multiple regression analysis. RESULTS: Tachycardia(aOR=136.5), altered mentality(aOR=28.8), decreased renal function(aOR=20.1), and significant comorbidity(aOR=17.2) are the independent factors associated with higher mortality. Altered mentality(aOR=31.6) and decreased renal function(CCr<75ml/min, aOR=5.4) are those associated with a higher incidence of septic shock. Independent factors associated with persistent(more than 3 days) fever are the early(within 10 days) onset of fever after last chemotherapy(aOR=8.8) and the existence of new pulmonary infiltrates on a simple chest X-ray(aOR=4.3). CONCLUSION: The stability of vital signs, the change of mentality, the renal function, the existence of significant comorbidity, the existence of new pulmonary infiltrates, and the rate of neutropenia are clinically useful risk-predication factors in febrile neutropenia at the time of visiting the emergency department.

The purpose of this study is to observe the effect of high pull headgear on the craniofacial structures of mixed dentition with Class II malocclusion. The cephalometric headplates of 16 children treated by high pull headgear during 6 months and 18 children during 12 months were traced, digitized and statistically analyzed. The results were as follows. 1. Inhibition of forward growth of maxilla was observed in both group. 2. Clockwise rotation of maxilla was observed in both group. 3. There were distal movement of maxillary 1st molar and inhibition of alveolar bone growth of maxilla. 4. There was compensatory extrusion on mandibular 1st molar. 5. The ratio of anterior facial height to posterior facial height was almostly not changed. In the treatment plan of C II malocclusion by high pull headgear, we must prevent the mandibulasr 1st molar from extruding, and for orthopedic effect, at least 6 months is needed.

The Ewing's sarcoma comprises approximately less than 10 percent of malignant bone tumors and 5 percent of allbone tumors, occures in almost all bones of the body, and presents a widely divergent roentgenographicmanifestations. The tarsal bones are involved only 2 percent in the Ewing's sarcoma. Two cases experienced byauthors and ten cases published in literatures of Ewing's sarcoma of the tarsal bone were analizedretrospectively. The result were as follows; 1. Of tarsal bones, the calcaneus was 7 cases, the talus 4 cases,cuneiform 1 case. 2. Female was affected more commonly than male, the ratio being 4 to 1 in the tarsal bones. 3.About sixty percent of total case in the tarsal bones had evidence of diffuse sclerotic pattern. All the cases ofthe talus had evidence of diffuse sclerotic pattern. 4. The diseases to be considered in differential diagnosisare as follows: avascular necrosis, tuberculous osteomyelitis, osteosarcoma, and pyogenic osteomyelitis. 5. Thediffuse sclerosis radiographically showed a close relation with dead bone resulting from avascular necrosis due totumor infiltration histologically. Periosteal reactive new bone and osteoid deposition on the dead bone were alsocorrelated with diffuse sclerosis. 6. Because it is difficult to differentiate sclerotic lesions in the tarsalbones by radiographic methods alone, all such lesions should be subject to biopsy as early as possible.
