ABSTRACT. On the basis of epidemiological data and medical costs for patients with neuroblastoma, we have calculated the cost of mass screening for neuroblastoma with high performance liquid chromatography (HPLC) compared to the cost when it is not performed. If the sensitivity of the mass screening is 80 % and 22 000 infants are screened annually the cost will be 27809000 yen ($191800). If mass screening is not performed, the cost will be 28 446 000 yen ($196 200). The difference in cost (637 000 yen or $4 400) is fairly small. If the sensitivity is 75 % and 16 500 infants are screened, the difference is also small (174000 yen or $1 200). Therefore, mass screening with the HPLC method will not be an undue financial burden. But re-screening at an older age will be done with less financially favorable results, considering that the sensitivity may not be as high as that of the first screening and that mothers are somewhat reluctant about re-screening. The balance of the cost of mass screening by qualitative methods may also be less favorable, since the detection rate is low. 相似文献

We report on two cases of women with locally advanced squamous cell carcinoma of the urethra. Patient 1 also displayed regional lymph node metastasis. Treatment comprised combined radiotherapy to 60 Gy and chemotherapy with 5-fluorouracil and cisplatin. Complete response was obtained in both patients, including the inguinal lymph nodes of Patient 1. Patient 1 experienced recurrent inguinal lymph node metastasis on the contralateral side at 42 months after initial treatment, and the same treatment was performed followed by surgical excision. Both patients remain alive with no evidence of disease, at 12 months after recurrence in Patient 1, and at 27 months after treatment in Patient 2. 相似文献

Acute renal failure and acute heart failure are rare in Kawasaki disease. We experienced two patients with Kawasaki disease who presented acute renal failure and acute heart failure. These two patients gave us an important insight into the understanding of water balance and fluid therapy in Kawasaki disease. One patient showed acute prerenal failure due to fluid exudation from the intravascular to the extravascular space, and subsequent acute heart failure. The other patient showed acute heart failure caused by fluid infusion for the treatment of dehydration. It is suggested that acute renal failure could be caused by a fluid shift from the intravascular to the extravascular space in Kawasaki disease. It is also demonstrated that the reserve of cardiac function could be decreased in patients with Kawasaki disease due to myocarditis even with normal echocardiography and chest X-rays. 相似文献

BACKGROUND: Retroperitoneal lymph node dissection (RPLND) following induction chemotherapy has been considered a critical component in the comprehensive management of advanced non-seminomatous germ cell tumors (NSGCT). The objectives of the present study were to review the clinical outcome of patients who underwent RPLND and to evaluate the probability of necrosis alone, based on some readily available clinical data for these patients. METHODS: Forty-seven consecutive patients with NSGCT were treated with first-line chemotherapy at our institution between January 1993 and September 2002. Twenty-four of these patients, who underwent RPLND with normal values of tumor markers after induction chemotherapy, were included in the study. The cause-specific survival rate was calculated using the Kaplan-Meier method. Various predictive factors for the histology were analyzed using multivariate analysis. RESULTS: The pathological findings at resection were necrosis alone in 62.5% of cases, teratoma in 25.0%, and viable cancer in 12.5%. The cause-specific 3-year survival rate of patients who underwent complete and incomplete resection was 100% and 50.0%, respectively. Among several clinical factors, prechemotherapy tumor size less than 50 mm was found to be an independent predictor of necrosis alone (hazard ratio = 4.45, P= 0.04). CONCLUSION: Metastatic tumor size before chemotherapy appears to be one of the most important factors for the prediction of necrosis alone in the resected specimens of RPLND. The prognosis of patients might be influenced by the degree to which resection has been completed. 相似文献

Unfolding profiles of two calcium-binding lysozymes, equine milk lysozyme and pigeon egg-white lysozyme, were obtained by circular dichroism and proton NMR measurements. Equine lysozyme unfolds through a stable molten globule intermediate. The molten globule of equine lysozyme was characterized as more ordered than that of bovine α-lactalbumin. On the other hand, pigeon lysozyme unfolds by a two-state mechanism and the intermediate could not be observed in guanidine or thermal unfolding, the same as with conventional non-calcium-binding lysozymes. Thus, from the point of view of the unfolding profile, equine lysozyme belongs to the group of α-lactalbumin, but pigeon lysozyme belongs to the conventional lysozyme group. 相似文献

A 30-year-old previously healthy housewife presented with bilateralpulmonary infiltrates. She was treated with various antibioticsbut died with disseminated intravascular coagulation. Culturesof tracheal aspirates obtained prior to her death yielded Trichosporonbeigelii. Postmortem examination revealed T. beigelii pneumoniawith fungal dissemination in other organs. In addition, manyorgans were found to be infiltrated with atypical mononuclearcells which exhibited cytochemical properties of histiocytes.It was considered, therefore, that T. beigelii pneumonia developedon the basis of underlying malignant histiocytosis. T. beigeliiin her lung sections was fluorescently stained with rabbit antiserumto the fungus isolated from the patient. This is the first reportof Trichosporon beigelii pneumonia associated with malignanthistiocytosis. 相似文献

Background: High-frequency oscillation ventilation (HFOV) is an accepted ventilatory mode for acute respiratory failure in neonates. As conventional mechanical ventilation, inspiratory gas humidification is essential. However, humidification during HFOV has not been clarified. In this bench study, we evaluated humidification during HFOV in the open circumstance of ICU. Our hypothesis is that humidification during HFOV is affected by circuit design and ventilatory settings.
Methods/Materials: We connected a ventilator with HFOV mode to a neonatal lung model that was placed in an infant incubator set at 37°C. We set a heated humidifier (Fisher & Paykel) to obtain 37°C at the chamber outlet and 40°C at the distal temperature probe. We measured absolute humidity and temperature at the Y-piece using a rapid-response hygrometer. We evaluated two types of ventilator circuit: a circuit with inner heating wire and another with embedded heating element. In addition, we evaluated three lengths of the inspiratory limb, three stroke volumes, three frequencies, and three mean airway pressures.
Results: The circuit with embedded heating element provided significantly higher absolute humidity and temperature than one with inner heating wire. As an extended tube lacking a heating wire was shorter, absolute humidity and temperature became higher. In the circuit with inner heating wire, absolute humidity and temperature increased as stroke volume increased.
Conclusion: Humidification during HFOV is affected by circuit design and ventilatory settings. 相似文献

Summary. Background: Activated protein C (APC) can regulate immune and inflammatory responses and apoptosis. Protein C transgenic mice develop less diabetic nephropathy but whether exogenous administration of APC suppresses established diabetic nephropathy is unknown. Objectives: We investigated the therapeutic potential of APC in mice with streptozotocin‐induced diabetic nephropathy. Methods: Diabetes was induced in unilaterally nephrectomized C57/Bl6 mice using intraperitoneal (i.p.) injection of streptozotocin. Four weeks later, the mice were treated with i.p. exogenous APC every other day for 1 month. Results: APC‐treated mice had a significantly improved blood nitrogen urea‐to‐creatinine ratio, urine total protein to creatinine ratio and proteinuria, and had significantly less renal fibrosis as measured by the levels of collagen and hydroxyproline. The renal tissue concentration of monocyte chemoattractant protein‐1 (MCP‐1), vascular endothelial growth factor (VEGF) and the RNA expression of platelet‐derived growth factor (PDGF), transforming growth factor‐β1 and connective tissue growth factor (CTGF) were significantly lower in APC‐treated mice than in untreated animals. The percentage of apoptotic cells was reduced and the expression of podocin, nephrin and WT‐1 in the glomeruli was significantly improved in mice treated with APC compared with untreated mice. The levels of coagulation markers were not affected by APC treatment. Conclusion: Exogenous APC improves renal function and mitigates pathological changes in mice with diabetic nephropathy by suppressing the expression of fibrogenic cytokines, growth factors and apoptosis, suggesting its potential usefulness for the therapy of this disease. 相似文献
