Abstract
SUMMARY Cerebral diagnostic and therapeutic angiography for neonatal arteriovenous fistulas is reported. Three neonatal boys with vein of Galen aneurysmal malformation (1 patient) and dural arteriovenous fistulas (2 patients) presented severe congestive heart failure soon after birth, and were treated by transarterial and/or transvenous embolization using various access routes. In the neonatal period, umbilical approach and direct cervical approach provide unique access routes in addition to the usual transfemoral route. Characteristics of neonatal angiography are discussed.

Abstract
OBJECTIVE Weekly administration of paclitaxel plus carboplatin is hypothesized to be an effective second-line treatment for advanced transitional cell cancer after failure of platinum-based regimen. In this phase 2 trial, we tested this hypothesis. PATIENTS AND METHODS Patients with advanced transitional cell cancer who showed evidence of progressive or recurrent disease after methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) therapy were eligible for this study. Weekly paclitaxel (80mg/m(2)) and carboplatin (AUC 2) were administered on days 1, 8, 15, 22, 29, and 36; the cycle was repeated every 7 wk until disease progression or intolerable toxicity (maximum 18 doses). RESULTS Thirty-five patients entered this study. Among the 31 patients who were assessable, 10 had an objective response (overall response rate: 32.3%, 95% confidence interval, 15.8-48.7%). The median progression-free survival (PFS) and median survival times were 3.7 and 7.9 mo, respectively. Among the 22 patients who received prior MVAC therapy for metastatic disease, 36% had an objective response; their median PFS and median survival times were 4.3 and 7.9 mo, respectively; neither survival time significantly differed from the survival time of those who received prior MVAC as adjuvant setting. Toxicities were mild except one toxic death due to neutropenic sepsis. CONCLUSIONS Weekly paclitaxel plus carboplatin was a manageable, active second-line treatment for advanced transitional cell cancer after failure of platinum-based therapy.

Abstract
We report a case of primary adenocarcinoma of the rete testis in a 55-year-old man with pulmonary metastases that were detected 11 months prior to the diagnosis of the primary lesion. Primary adenocarcinoma of the rete testis is an extremely rare malignant tumor with a poor outcome. The most common primary symptom is a scrotal mass, often accompanied by hydrocele and chronic epididymitis. The diagnosis is often delayed because of non-specific clinical presentation and symptoms. We cannot forget that rete testis is a possible primary site for a primary, unknown metastatic adenocarcinoma.

Abstract
Several types of recurrence may be detected by radiologic assessment after treatment in patients with prostate cancer. However, early detection of distant metastasis using positron emission tomography has so far never been published. We report two patients who underwent hormone therapy or surgical resection for prostate cancer. They developed distant metastases which were detected on whole body [C-11] choline positron emission tomography/computed tomography with significant elevation of serum PSA level. In one patient, recurrent tumor of the supraclavicular node (6 mm) diminished in size after subsequent hormone therapy. Surgical resection of recurrent tumor of the lung (12 mm) was performed in the other patient, the pathology of which confirmed the metastatic adenocarcinoma derived from the prostate. The recurrent tumor can be correctly detected by dual-phase whole body [C-11] choline positron emission tomography/computed tomography.

Abstract
Here, we report a patient with renal failure and bladder dysfunction whose symptoms improved following renal transplantation. A 23-year-old woman underwent renal transplantation for renal failure as a result of dysplastic kidneys. Urodynamic evaluation prior to transplantation showed decreased bladder sensation and increased bladder capacity, probably because of congenital polyuria. One week after surgery, dry mouth disappeared, and urine volume normalized gradually. Urodynamic studies performed 3 and 10 months after transplantation showed improvement of bladder function, and the frequency/volume charts of urination also showed normalization of urine volume. Renal and bladder functions were almost normal 45 months after transplantation. Bladder dysfunction involves numerous factors, but the primary cause was probably congenital polyuria in the present case. This case suggested that blood purification and correction of urine volume by renal transplantation might lead to restoration of normal bladder function.

Abstract
SUMMARY The purpose of this literature review is to disclose the relationship between the temporal profile of steno-occlusive changes in the cerebral arteries in moyamoya disease and the embryological evolution of the cerebral arteries. Steno-occlusive changes and progression occur in the sequence of embryological evolution of the primitive internal carotid artery in the early embryological stage. In other words, steno-occlusive changes in the cerebral arteries occur primarily near the bifurcation of the cranial and caudal divisions of the primitive internal carotid artery, evolve from the cranial division to the caudal one, and progress from the bifurcation centrifugally. Steno-occlusive changes do not occur essentially in the distal cortical branches of the primitive internal carotid artery, in any arteries in the external carotid system, which are derived from ventral pharyngeal system and primitive stapedial system, or in any cerebral arteries in the vertebrobasilar system, which are derived from the longitudinal neural arteries.These facts suggest that moyamoya disease is strongly related to the vasculogenesis of the primitive internal carotid artery and genetic factors play a major role in the clinical manifestations of moyamoya disease.

Abstract
OBJECTIVE The aim of this study was to evaluate the safety and efficacy of allogeneic hematopoietic stem cell transplantation with a reduced-intensity conditioning regimen (RIST) for interferon-alpha-refractory metastatic renal cell carcinoma (RCC). PATIENTS AND METHODS Of 26 patients referred to the National Cancer Center Hospital for possible RIST between June 2000 and April 2002, an HLA-identical relative was identified for 12 patients. Nine patients underwent RIST. The conditioning regimen consisted of fludarabine 180 mg/m2 or cladribine 0.66 mg/kg, plus busulfan 8 mg/kg and rabbit antithymocyte globulin 5 mg/kg. Graft-vs-host disease (GVHD) prophylaxis was cyclosporine alone. RESULTS All patients achieved engraftment without grade III to IV nonhematologic regimen-related toxicity. All patients achieved complete donor-type chimerism without donor lymphocyte infusion by day 60. Four patients developed acute GVHD, and four developed chronic GVHD. One patient (11%) achieved partial response. As of July 2003, six patients were alive at median follow-up of 681 days. The actuarial overall survival rate was 89% at 1 year and 74% at 2 years. The overall survival rate tended to be higher in the 12 patients with a matched donor than in the other 14 patients without a matched donor (p = 0.088). CONCLUSION Our RIST procedure is feasible without severe toxicity. The efficacy of RIST for RCC should be confirmed in phase II/III clinical trials.

Abstract
BACKGROUND We evaluated whether color Doppler ultrasound (US) had diagnostic accuracy equal to dynamic computed tomography (CT) and whether performing dynamic CT and Doppler US together would be more informative in preoperative diagnosis of renal solid tumors. METHODS A total of 110 renal solid tumors smaller than 7 cm were evaluated with dynamic CT and Doppler US. We compared the enhancement and the color flow patterns with the histopathological subtypes. RESULTS Eighty-seven (95.6%) of 91 clear cell carcinomas showed rich enhancement in the cortical nephrographic phase (CNP) and 82 (90.1%) of them had color flow in the Doppler US. Of the total of 110 tumors, nine (8.1%) did not show color flow in spite of rich enhancement in the CNP. Conversely, eight (7.2%) of the 110 tumors showed color flow in spite of poor enhancement, including two chromophobe cell carcinomas and two metastatic renal tumors. CONCLUSIONS The enhancement pattern in dynamic CT and the color flow pattern in Doppler US were different among the subtypes of RCC. Color Doppler US had diagnostic accuracy equal to dynamic CT in most patients with renal solid tumors. Although Doppler US may play a unique role in the diagnosis of some renal parenchymal solid tumors, it is sufficient to perform dynamic CT alone for diagnosis of clear cell carcinoma.

Abstract
Homogeneous Ce(IV) complex of EDTA promptly hydrolyzes oligonucleotides under physiological conditions. Moreover, the activity of Ce(IV)/EDTA for DNA hydrolysis is promoted by the addition of amines. When [Ce(IV)/EDTA] = 5 mumol dm3 and [ethylenediamine] = 100 mmol dm3, the catalytic activity is about 50 times as large as that of Ce(IV)/EDTA. The combination of Ce(IV)/EDTA and amines is eminent tools for the future molecular biology and biotechnology.

Abstract
Modified DNA carrying an azobenzene was successfully applied to the photo-regulation of DNA/RNA hybridization. When the azobenzene was isomerized from trans- to cis-form on UV-irradiation, the melting temperature of the duplex was significantly lowered. This process was totally reversible so that the Tm increased by cis-->trans isomerization induced by visible light irradiation.
