Abstract
BACKGROUND To prevent infectious complications after transrectal ultrasound-guided prostate biopsy (TRUS-PB), some studies have investigated the efficacy of rectal disinfection using povidone-iodine (PI) and antibiotic prophylaxis (AP). OBJECTIVE To summarize available data and compare the efficacy of rectal disinfection using PI with non-PI methods prior to TRUS-PB. EVIDENCE ACQUISITION Three databases were queried through November 2023 for randomized controlled trials (RCTs) analyzing patients who underwent TRUS-PB. We compared the effectiveness of rectal disinfection between PI groups and non-PI groups with or without AP. The primary outcomes of interest were the rates of overall infectious complications, fever, and sepsis. Subgroups analyses were conducted to assess the differential outcomes in patients using fluoroquinolone groups compared to those using other antibiotics groups. EVIDENCE SYNTHESIS We included ten RCTs in the meta-analyses. The overall rates of infectious complications were significantly lower when rectal disinfection with PI was performed (RR 0.56, 95% CI 0.42-0.74, p < 0.001). Compared to AP monotherapy, the combination of AP and PI was associated with significantly lower risk of infectious complications (RR 0.54, 95% CI 0.40-0.73, p < 0.001) and fever (RR 0.47, 95% CI 0.30-0.75, p = 0.001), but not with sepsis (RR 0.49, 95% CI 0.23-1.04, p = 0.06). The use of fluoroquinolone antibiotics was associated with a lower risk of infectious complications and fever compared to non-FQ antibiotics. CONCLUSION Rectal disinfection with PI significantly reduces the rates of infectious complications and fever in patients undergoing TRUS-PB. However, this approach does not show a significant impact on reducing the rate of sepsis following the procedure.

Abstract
CONTEXT It remains unclear to what extent the therapy of the primary local tumor, such as radical prostatectomy (RP) and radiation therapy (RT), improves overall survival in patients with low-volume metastatic hormone-sensitive prostate cancer (mHSPC). However, data suggest a benefit of these therapies in preventing local events secondary to local tumor progression. OBJECTIVE To evaluate the efficacy of adding local therapy (RP or RT) to systemic therapies, including androgen deprivation therapy, docetaxel, and/or androgen receptor axis-targeted agents, in preventing local events in mHSPC patients compared with systemic therapy alone (ie, without RT of the prostate or RP). EVIDENCE ACQUISITION Three databases and meeting abstracts were queried in November 2023 for studies analyzing mHSPC patients treated with local therapy. The primary outcome of interest was the prevention of overall local events (urinary tract infection, urinary tract obstruction, and gross hematuria) due to local disease progression. Subgroup analyses were conducted to assess the differential outcomes according to the type of local therapy (RP or RT). EVIDENCE SYNTHESIS Overall, six studies, comprising two randomized controlled trials, were included for a systematic review and meta-analysis. The overall incidence of local events was significantly lower in the local treatment plus systemic therapy group than in the systemic therapy only groups (relative risk [RR]: 0.50, 95% confidence interval [CI]: 0.28-0.88, p = 0.016). RP significantly reduced the incidence of overall local events (RR: 0.24, 95% CI: 0.11-0.52) and that of local events requiring surgical intervention (RR: 0.08, 95% CI: 0.03-0.25). Although there was no statistically significant difference between the RT plus systemic therapy and systemic therapy only groups in terms of overall local events, the incidence of local events requiring surgical intervention was significantly lower in the RT plus systemic therapy group (RR: 0.70, 95% CI: 0.49-0.99); local events requiring surgical intervention of the upper urinary tract was significantly lower in local treatment groups (RR: 0.60, 95% CI: 0.37-0.98, p = 0.04). However, a subgroup analysis revealed that neither RP nor RT significantly impacted the prevention of local events requiring surgical intervention of the upper urinary tract. CONCLUSIONS In some patients with mHSPC, RP or RT of primary tumor seems to reduce the incidence of local progression and events requiring surgical intervention. Identifying which patients are most likely to benefit from local therapy, and at what time point (eg, after response of metastases), will be necessary to set up a study assessing the risk, benefits, and alternatives to therapy of the primary tumor in the mHSPC setting. PATIENT SUMMARY Our study suggests that local therapy of the prostate, such as radical prostatectomy or radiotherapy, in patients with metastatic hormone-sensitive prostate cancer can prevent local events, such as urinary obstruction and gross hematuria.

Abstract
The Japanese surveillance committee conducted a third nationwide surveillance of antimicrobial susceptibility of acute uncomplicated cystitis at 55 facilities throughout Japan between April 2020 and September 2021. In this surveillance, we investigated the susceptibility of Escherichia coli (E. coli), Klebsiella pneumoniae (K. pneumoniae), and Staphylococcus saprophyticus (S. saprophyticus) for various antimicrobial agents by isolating and culturing bacteria from urine samples. In total, 823 strains were isolated from 848 patients and 569 strains of target bacteria, including E. coli (n = 529, 92.9 %), K. pneumoniae (n = 28, 4.9 %), and S. saprophyticus (n = 12, 2.2 %) were isolated. The minimum inhibitory concentrations of 18 antibacterial agents were determined according to the Clinical and Laboratory Standards Institute manual. In premenopausal patients, there were 31 (10.5 %) and 20 (6.8 %) fluoroquinolone (FQ)-resistant E. coli and extended-spectrum β-lactamase (ESBL)-producing E. coli, respectively. On the other hand, in postmenopausal patients, there were 75 (32.1 %) and 36 (15.4 %) FQ-resistant E. coli and ESBL-producing E. coli, respectively. The rate of FQ-resistant E. coli and ESBL-producing E. coli in post-menopausal women was higher than that for our previous nationwide surveillance (20.7 % and 32.1 %: p = 0.0004, 10.0 % and 15.4 %; p = 0.0259). For pre-menopausal women, there was no significant difference in the rate of FQ-resistant E. coli and ESBL-producing E. coli between this and previous reports, but the frequency of FQ-resistant E. coli and ESBL-producing E. coli exhibited a gradual increase. For appropriate antimicrobial agent selection and usage, it is essential for clinicians to be aware of the high rate of these antimicrobial-resistant bacteria in acute uncomplicated cystitis in Japan.

Abstract
Introduction Small cell bladder cancer is a relatively rare tumor, representing <1% of all bladder tumors. Amrubicin monotherapy is used as second-line treatment for small cell lung cancer in Japan. Case presentation A 79-year-old woman presented with gross hematuria and was diagnosed with small cell bladder cancer (T2 or higher). Neoadjuvant chemotherapy with etoposide and cisplatin resulted in a partial response. Robot-assisted radical cystectomy was performed, and radical resection was achieved. As we identified metastasis in the pleura 1 year later, we administered carboplatin and etoposide, which resulted in a partial response. Although pembrolizumab was initiated as maintenance therapy, it was not effective. Amrubicin was given as third-line therapy, and stable disease was achieved without serious adverse effect for 6 months. Conclusion Although there is no established treatment for metastatic small cell bladder cancer, the current case report suggests the effectiveness of amrubicin in this setting.

Abstract
PURPOSE Radiological tumor burden has been reported to be prognostic in many malignancies in the immunotherapy era, yet whether it is prognostic in patients with metastatic urothelial carcinoma (mUC) treated with pembrolizumab remains uninvestigated. We sought to assess the predictive and prognostic value of radiological tumor burden in patients with mUC. METHODS We performed a retrospective analysis of 308 patients with mUC treated with pembrolizumab. Radiological tumor burden was represented by baseline tumor size (BTS) and baseline tumor number (BTN). Optimal cut-off value of BTS was determined as 50 mm using the Youden index (small BTS: n = 194, large BTS: n = 114). Overall (OS), cancer-specific (CSS), progression-free survival (PFS), and objective response rate (ORR) were compared. Non-linear associations between BTS and OS and CSS were evaluated using restricted cubic splines. RESULTS Patients with large BTS were less likely to have undergone the surgical resection of the primary tumor (P = 0.01), and more likely to have liver metastasis (P < 0.001) and more metastatic lesions (P < 0.001). On multivariable analyses controlling for the effects of confounders (resection of primary tumor, metastatic site, number of metastases and lactate dehydrogenase level), large BTS and high BTN were independently associated with worse OS (HR 1.52; P = 0.015, and HR 1.69; P = 0.018, respectively) and CSS (HR 1.59; P = 0.01, and HR 1.66; P = 0.031, respectively), but not PFS. Restricted cubic splines revealed BTS was correlated with OS and CSS in linear relationships. Additionally, large BTS was significantly predictive of lower ORR and complete response rate on univariable analyses (P = 0.041 and P = 0.032, respectively), but its association disappeared on multivariable analyses. CONCLUSION Radiological tumor burden has independent prognostic value with a linear relationship in pembrolizumab-treated patients with mUC and might help drive the earlier introduction of second-line pembrolizumab and/or switching to subsequent therapies.

Abstract
PURPOSE To investigate the efficacy of continuous suturing using barbed suture for vesicourethral anastomosis (VUA) during robot-assisted laparoscopic radical prostatectomy (RARP). MATERIALS AND METHODS Seventy-three consecutive patients who underwent RARP by a single surgeon between 2020 and 2022 were retrospectively divided based on the suture type used for VUA: group A, 3-0 poliglecaprone-25 RB-1 needle (Monocryl®), n = 46; group B, 3-0 spiral polydioxanone (PDS) barbed suture with RB-1 needle (STRATAFIX®), n = 27. RESULTS There was no significant difference in patient background characteristics between groups, including age, body mass index, and clinical stage. However, group B had a significantly shorter operative time, console time, hospital stay, and duration of urethral catheterization. The VUA time was significantly shorter in group B than in group A (17.9 min vs. 10.6 min; p < 0.001). Only 1 case of minor leakage was observed during the intraoperative leak test (1 patient in group A). There was no significant difference in the number of pads used at 1, 3, 6 months and 1 year postoperatively. There were no urethral strictures, and there was no significant difference in pathologic results or postoperative prostate-specific antigen progression between groups. CONCLUSIONS Our study suggests that the use of barbed suture during VUA for RARP is associated with reduced VUA time.

Abstract
Introduction Radiation therapy is used as primary, adjuvant, and salvage therapy for prostate cancer. When using radiation therapy, the SpaceOAR® system is considered easy to use and useful for reducing the irradiated dose and toxicity to the rectum. Although SpaceOAR® system have been reported some adverse event including death. Case presentation A 74-year-old male was diagnosed with prostate cancer of clinical stage cT2aN0M0 and intermediate risk by the National Comprehensive Cancer Network guidelines. We inserted the SpaceOAR® Hydrogel before performing intensity-modulated radiation therapy, as the patient had ulcerative colitis. We did not recognize any complications during or after the procedure, although magnetic resonance imaging revealed hydrogel in the bladder retrospectively. Fourteen months after the procedure, the patient was presented with macrohematuria and we found a bladder stone including hydrogel. Conclusion We report the first case of a bladder stone after use of SpaceOAR® Hydrogel. We must be careful of taking place it.

Abstract
Introduction Obstruction of a ureteroileal anastomosis after urinary diversion is an unpleasant situation for patients and clinicians alike. Case presentation A 48-year-old man who underwent a radical cystectomy for muscle-invasive bladder cancer and urinary diversion using the Wallace technique complained of right back pain. Computed tomography showed right hydronephrosis. Cystoscopy via the ileal conduit revealed complete obstruction of the ureteroileal anastomosis. We performed a bilateral approach (antegrade and retrograde) to use the cut-to-the-light technique. A guidewire and 7Fr single J catheter could be inserted. Conclusion The cut-to-the-light technique was useful for complete obstruction of the ureteroileal anastomosis, the length of which was <1 cm. Herein, we report on the cut-to-the-light technique with a literature review.

Abstract
Introduction Penile fracture is typically defined as the rupture of the corpus cavernosum. Case presentation A 61-year-old man presented with swelling, pain, and bruising of his penis, along with gross hematuria. He reported that he sustained this injury while having sex with his wife. We suspected a penile fracture and obtained magnetic resonance imaging, which showed a rupture of the ventral corpus spongiosum and clarified the appropriate approach for repair. We used a direct transverse incision to repair both the urethral injury and the corpus spongiosum. Surgery went well, without any significant intraoperative or postoperative complications. We removed the urinary catheter on postoperative day 8, and cystoscopy showed no urethral stenosis on postoperative day 17. The patient's postoperative erectile function was the same as before his injury. Conclusion Magnetic resonance imaging was useful for detect the site of rupture. Ventral direct transverce incision made him a good clinical course.

Abstract
The development of several culture media and the availability to isolate and treat pathogens prior to a surgical procedure give us the ability to minimize treatment-related complications, and ultimately results in better outcomes for patients and avoidance of unwanted post-procedure inpatient admissions. In the last decade, an increasing incidence of multidrug-resistant Escherichia coli, especially extended-spectrum beta-lactamase-producing E. coli and fluoroquinolone-resistant pathogens, has been reported. These resistant species frequently colonize the rectal flora and gain access to the systemic circulation via the rectal plexus following a prostate biopsy. The bacteria can eventually lead to life-threatening complications, which is especially important in high-risk patients with multiple co-morbidities. Previously published studies have focused on the isolation of these pathogens with selective media before an invasive procedure and the potential benefits of incorporating the use of selective media as a mandatory pre-operative step. This preventive measure will allow us to offer a tailored prophylactic treatment that benefits patients and reduces the economic burden for the hospital.

Abstract
Purpose To evaluate the efficacy of holmium laser enucleation of the prostate (HoLEP) in patients with a small prostate volume (≤30 mL). Materials and Methods We retrospectively evaluated 1,135 patients who underwent HoLEP at two institutions between July 2007 and March 2020. Patients who were not evaluated for the International Prostate Symptom Score (IPSS) before or after HoLEP were excluded. We divided patients into two groups according to estimated prostate volume (ePV): ≤30 (n=198) and >30 mL (n=539). The patient characteristics, IPSS, peak urinary flow rate (Qmax), postvoid residual urine volume (PVR), and other data were compared before and after surgery in each group and between the two groups. Multivariate analysis was performed to identify the factors associated with the efficacy of HoLEP in the group with ePV ≤30 mL. Results A total of 737 patients were included in this retrospective study. ePV (23.4 mL vs. 50 mL; p<0.001) and PVR differed significantly between the two groups. The IPSS, IPSS-quality of life, PVR, and Qmax significantly improved after HoLEP in both groups. Improvements in the IPSS, IPSS-quality of life, Qmax, and PVR were greater in the >30 mL group (p<0.001), whereas operation time and morcellation time were significantly shorter in the ≤30 mL group. In the multivariate analysis, age <70 years was independently associated with improvement by HoLEP. Conclusions HoLEP is an effective treatment for patients with a small prostate, even though the extent of improvement after HoLEP was greater in those with a larger prostate.

Background
Right ventricular (RV) pacing causes changes of the electrical and mechanical activation pattern of the heart. QRS duration is reported to be a useful surrogate marker of electrical dyssynchrony, and wider QRS duration during RV pacing indicates poor prognosis. However, the mechanism of widening QRS duration during RV pacing remains to be elucidated.
Methods
A total of 211 patients who underwent catheter ablation for supraventricular tachyarrhythmias and have no bundle-branch-block on ECG were enrolled. During electrophysiological study, 3-dimensional mapping for QRS duration during RV pacing from RV outflow to RV apex was created, and the difference of QRS duration between RV outflow and RV apex was calculated. The relationship between QRS duration during RV pacing and patients' baseline characteristics including echocardiography data was analyzed.
Results
QRS duration at baseline, during RV pacing from RV outflow, and RV apex were 85.0±7.5msec, 156.2±16.1msec, and 163.7±17.1msec, respectively. The difference of QRS duration between RV outflow and RV apex among patients was only 12.5±10.4msec. The logistic multivariable regression analysis showed baseline QRS duration (odds ratio (OR) 1.24, 95% CI 1.15 to 1.34, p<0.01), interventricular septum thickness (OR 1.35, 95% CI 1.05 to 1.73, p=0.018), and E/e' (OR 1.23, 95% CI 1.12 to 1.36, p<0.01) were significant predictors for QRS duration over 160msec during RV apical pacing.
Conclusions
QRS duration during RV pacing depends largely not on the pacing site, but on the underlying structural heart disease.

Abstract
Nephron-sparing treatment should be offered whenever possible to avoid dialysis in allograph cases. Cryoablation is a new treatment option for treating small-sized renal cell cancer (RCCs). We report a case of RCC arising in a kidney allograft treated by cryoablation. To our knowledge, this is the first case in Asia of RCC in a renal allograft treated using cryoablation. Contrast-enhanced CT-guided percutaneous renal needle biopsy and cryoablation were used to identify the RCC, which could not be identified by other techniques. The postoperative course was uneventful. Contrast-enhanced CT also showed no recurrence or metastases at the 6-month follow-up.

Abstract
Abstract
Introduction
Although radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF) has become a standard therapy, the ablation outcomes in patients undergoing hemodialysis (HD) has not been fully elucidated. The present study aimed to evaluate the clinical outcomes of RFCA for AF in patients undergoing HD.
Methods
Twenty-three patients undergoing HD (17 men, age 65±8 years, 19 paroxysmal AF) who underwent RFCA for drug-refractory AF in two institutes were enrolled in the study and defined as HD group. The clinical parameters, recurrence free rate and frequency of periprocedural complications were compared to 46 randomly selected age, gender and left atrial diameter matched controls not requiring HD defined as non-HD group (34men, age 67±7 years, 38 paroxysmal AF).
Results
The patients in HD group had a significantly lower body mass index (21±3 vs. 25±3 P<0.01), higher prevalence of coronary artery disease (30% vs. 10% P=0.04), and higher prevalence of congestive heart failure (52% vs. 10% P<0.01) compared to patients in non-HD group. Echocardiography indicated lower left ventricular ejection fraction (57±17% vs. 65±9% P=0.02), higher E/e' (20±8 vs. 12±4 P<0.01), higher tricuspid regurgitation pressure gradient (30mmHg vs. 24mmHg P<0.01) and more impaired left ventricular diastolic function in HD group. All the subjects underwent bilateral pulmonary vein isolation plus additional linear lesion. The number of ablation procedure was similar between the two groups (1.43±0.5 vs. 1.46±0.6 P=0.88). During the follow-up period of 37±25 months after the last procedure, the arrhythmia free rate was similar between the two groups (86% vs. 84% log-rank P=0.82). Vascular access complication occurred in two patients in HD group, and pericardial effusion occurred in one patient in non-HD group, while no life-threatening complications were observed in either group. Cardiogenic cerebral infarction occurred in one patient in non-HD group. Discontinuation of oral anticoagulation after the ablation was more often seen in the HD group compared to non-HD group (91% vs. 60% P<0.01).
Conclusions
Although patients undergoing HD had more impaired left ventricular systolic and diastolic function, RFCA for AF in patients with HD was shown to be as effective and safe as in non-HD patients. RFCA may be an efficient approach to manage AF in patients undergoing HD.

Abstract
Introduction An inflammatory myofibroblastic tumor of the bladder is rare. Some urothelial carcinoma with sarcomatoid changes may mimic an inflammatory myofibroblastic tumor. Case presentation A 76‐year‐old man with indwelling urinary catheters because of a spinal cord injury presented with gross hematuria. Transurethral electrocoagulation and a resection were performed. A T2‐weighted magnetic resonance imaging showed a tumor and hematoma in the bladder diverticulum that pathologically resembled an inflammatory myofibroblastic tumor. This lesion was then removed en bloc by partial cystectomy. Histology showed a squamous cell carcinoma with sarcomatoid changes. After 4 months, a computed tomography showed the lesion had expanded outside the skin adjacent to the bladder. Conclusion Some cases of inflammatory myofibroblastic tumors have a malignant course. Urologists therefore need to be aware of the possibility of rare cases of malignant bladder myofibroblasts.

Abstract
Abstract
Background: It is known that ER-positive breast cancer constitutes approximately 70% of all breast cancer and the particular population of these, called as luminal A breast cancer can lead to late recurrence, possibly due to the presence of dormant tumor cells. It is also argued that there are many similar biological characteristics between dormant cells and cancer stem cells (CSCs). So we hypothesized that some part of CSCs would be involved in the late recurrence of luminal type breast cancer and looked for the factors correlateing late recurrence by comparing CSC-enriched population and other population. Materials and Methods: We used the MCF-7 and HCC1500 human breast cell lines. Moreover, we isolated the BC#1 breast cancer cell from metastatic pleural effusion of a breast cancer patient (79 years old, ER+, PgR+, HER2 score 0). These cells are cultured in the adhesion culture condition or the mammosphere culture condition. The immunohistochemical characteristics such as ER, PgR, HER2, Cytokeratin (CK) 8, CK5/6 status of these cells were confirmed. The analysis of the ALDH activity and the CD44+/24- expression as the CSC marker were carried out using flow cytometry. The expression of target genes was analyzed using quantitative RT-PCR. Protein expression was determined by western-blotting. To assess the self-renewal potential of CSCs and the proliferation of immature cancer cells, we used mammosphere formation assay and colony formation assay. To investigate the effects of 4-hydroxytamoxifen(4-OHT) on mammosphere formation assay, 1µm of 4-OHT added to the medium in the particular experiment. Results: BC#1 was confirmed as luminal type by immunohistochemistry and qRT-PCR. The expression tendency between two CSC markers are almost same and correlated to the mammosphere formation capacity. We also confirmed that mammosphere culture have an increased ALDH-positive population compared with adherent culture cells. Using flow cytometry, we divided the cell lines and isolated cells into two populations, ALDH-positive and negative. By qRT-PCR analysis, ALDH-positive population showed higher expression of FOXA1 (ER expression related gene) than ALDH-negative population. In addition, we found the significantly higher expression of FOXA1 gene, and RPRM gene (p53 induced G2/M arrest related gene) in mammosphere culture samples than in adhesion culture samples. In terms of the effects of 4-OHT, 4-OHT resistant mammosphere samples showed significantly increased FOXA1 gene expression level. Finally, we established shFOXA1 MCF-7 cells to investigate the relationship between self-renewal potential and FOXA1 expression. We found that colony formation in shFOXA1 MCF-7 cells decreased compared with control while there is no significant difference in the number of mammospheres. Conclusion: CSC-enriched population showed higher FOXA1 expression and our results suggested that the expression of FOXA1 correlate to the proliferation of immature breast cancer cell rather than the induction of self-renewal potency of CSCs. Moreover, there is no report argued about the correlation between CSCs and G2/M arrest related gene like RPRM so that the biological mechanism should be investigated in future.

Abstract
OBJECTIVE The purpose of this study was to evaluate the reliability of inter-and intra-observer assessments of the mechanical alignment of the lower extremities with digitally computed radiographs of an anterior-posterior view of the whole leg using a new computer-assisted method. METHOD Load bearing axis deviation of the lower extremities was quantitatively measured by three examiners in 105 knees of 73 subjects who had osteoarthritis of the knee with a Kellgren-Lawrence grade of 1 or more. A line representing the load bearing axis was drawn from the center of the femoral head to the center of the ankle and the alignment of the leg was assessed by measuring the width of the proximal tibia and the perpendicular distance from the middle of the proximal tibial condyle to the load bearing axis (Fujifilm OP-A). A ratio of the values was calculated and expressed as a percentage. RESULTS The inter-observer mean difference was 2.9 % (SD, 2.7), and the intra-observer mean difference was 2.1% (SD, 2.2). The mean intraclass correlation coefficient (ICC) for inter-observer trials was 0.96; that for intra-observer trials was 0.99. CONCLUSION Our computer-assisted method was reproducible, and should be considered an alternative method for the measurement of the alignment of the whole leg.

Abstract
Following CNS injury, microglia respond and transform into reactive species exhibiting characteristic morphological changes that have been termed "activated" or "ameboid" microglia. In an attempt to establish that microglial reactions induced immediately after injury are caused by intrinsic mechanisms rather than infiltration of blood and its constituents, oxygenized Ringer's solution was perfused into the cerebral circulation of rats so that the circulating blood could be eliminated prior to injury induction. Under artificial respiration, a catheter was inserted from the cardiac apex into the ascending aorta, and oxygenized Ringer's solution was immediately perfused with a pulsatile blood pump, resulting in wash out of the circulating blood from the brain within 1 min. Subsequently, a cortical contusion was induced in the unilateral parietal cortex using a controlled cortical impact (CCI) device. At 5 min following the injury, the brain was fixed by perfusion of fixative through the catheter and removed. Coronal vibratome sections were then processed for CR3 immunohistochemistry to examine the microglial activation. It appeared that microglial activation with both morphological transformation and an increase in CR3 immunoreactivity was induced throughout the hemisphere ipsilateral to the injury side exclusively, even in rats with elimination of circulating blood. The microglial reactions did not differ substantially from those observed in the control rats with extensive BBB disruption. The present results thus provide direct evidence that the microglial activation induced immediately after injury is independent of infiltration of circulating blood induced by concurrent BBB disruption.

Abstract
Because IL-3-dependent multipotential FDCP-Mix cells expressing human colony-stimulating factor-1 (CSF-1) receptor did not proliferate in response to soluble CSF-1, we investigated whether their proliferation would be induced in co-culture with adherent cells expressing the membrane form of CSF-1 (MemCSF-1). FDCP-Mix cells with high CSF-1R expression (NAF21 cells) were placed on stromal MS-5 cells or STO fibroblasts expressing MemCSF-1 (2M-1 cells and STO-M2 cells, respectively), in absence of IL-3. NAF21 cells bound significantly to 2M-1 cells as compared to control FDCP-Mix cells. Adhesion of NAF21 cells was inhibited by anti-huCSF-1 antibodies, as well as anti-huCSF-1R antibodies. Interestingly, NAF21 cells proliferated on both 2M-1 and STO-M2 cells but with very different kinetics. Moreover, NAF21 cell proliferation was also supported by glutaraldehyde-fixed 2M-1 cells or highly concentrated MS-5 cell culture supernatant, but not by CSF-1 coated on culture dishes. These results strongly suggest that MemCSF-1/CSF-1R interaction mediates a specific adhesion of NAF21 cells to stromal cells and allows stimulation of hematopoietic cells by stromal cell-derived factors expressed in a membrane-bound form or concentrated within the extracellular matrix. Thus, cytokine receptors deficient in mitogenic signalling may nevertheless have a regulatory role in hematopoietic progenitor cell proliferation by acting as adhesion molecules.

Abstract
A 73-year-old man was admitted to our hospital in July 1996 because of lymphoctyosis and lumbago. Physical examination revealed hepatomegaly and anemia. Hematologic examination showed a hemoglobin concentration of 9.6 g/dl and a leukocyte count of 32,700/microliter with 74% abnormal mononuclear cells. In Wright-Giemsa stained blood films, these cells had short villi arising from 1 or 2 poles. Immunophenotyping of peripheral mononuclear cells showed moderate to strong expression of CD10, CD24, CD38, and sIg lambda, but not of CD19, CD20, or CD25. Southern blot analysis of the peripheral mononuclear cells demonstrated rearranged monoclonal bands in the C lambda. Urine immunoelectrophoresis detected a monoclonal band identifiable as lambda-type Bence Jones protein. In addition, bone X-ray studies disclosed multiple osteolytic lesions. A diagnosis of plasma cell leukemia was made, and the patient was placed on chemotherapy consisting of cyclophosphamide and prednisolone. No notable improvement in laboratory findings was seen but the patient experienced an indolent clinical course. He died of pneumonia in January 1998. The morphological and clinical findings were unusual for a case of plasma cell leukemia. This case study suggested that signs of lymphocytosis require immunophenotypic and electron microscopic studies for the differential diagnosis of plasma cell leukemia.

Young mice injected with LPS exhibited: (a) increased femoral proliferative pool size; (b) transient reduction in femoral non-proliferative pool size and number of femoral colony forming unit-granulocyte macrophages (CFU-GMs); (c) marked increase in splenic CFU-GMs; and (d) transient increase in S-phase of femoral CFU-GMs. The responses of old mice after LPS administration differed from those of young mice in the following points: (a) no recovery of the femoral non-proliferative pool or femoral CFU-GMs, (b) less significant augmentation of the femoral proliferative pool and splenic CFU-GMs, and (c) prolonged reduction in S-phase of femoral CFU-GM. Injection of LPS into mice resulted in a hyperproduction of colony-stimulating activity (CSA) in bone followed by production of colony-inhibitory activity (CIA) in young mice and in contrast, an excessive CIA secretion from bone without an increase in CSA levels in old mice. These imbalances in the regulatory factors derived from non-hemopoietic cells in the bones may lead to an inappropriate response of myelopoiesis in aged SAM mice after LPS administration, which may play a key role in infections.

Abstract
A case of a 66-year-old Japanese man developed therapy-related megakaryoblastic leukemia with pituitary involvement after chemotherapy for non-Hodgkin's lymphoma. Alkylating agents had been administered for the treatment of non-Hodgkin's lymphoma and 6 years later, megakaryoblastic leukemia with myelofibrosis and myelodysplasia developed. The blast cells expressed CD41, and immature antigens also. These findings were compatible with therapy-related megakaryoblastic leukemia. An autopsy revealed blast-cell infiltration into multiple organs including the posterior pituitary lobe. Therapy-related megakaryoblastic leukemia is very rare, and pituitary involvement may be associated with immaturity of blast cells.

Abstract
In this study, to clarify whether the functional capacity of hemopoietic progenitor cells and the micro-environment of aged mice are identical with those of the young, we investigated the changes in the number of hemopoietic progenitor cells and the production of regulatory cytokines from splenic cells as well as changes in the serum levels of cytokine in senescence-accelerated mice (SAM) after administration of 19-nandrolone decanoate (19-ND), a synthetic androgenic anabolic steroid. 19-ND induced an increase in erythroid colony-forming units (CFU-E), erythroid burst-forming units (BFU-E), and granulocytic-macrophage committed progenitor cells (CFU-GM) in bone marrow and spleen; especially remarkable increases were observed in the splenic CFU-E in both young and old mice. Antigen expression analysis of hemopoietic organs revealed that total TER-119+ cells per spleen of young and old mice with androgen treatment rose 2.6- and 3.2-fold over their respective control values. The responsiveness of hemopoietic progenitor cells to androgen did not change with age. Injection of 19-ND into young and old mice markedly enhanced the erythropoietin levels but not IL3 and GM-CSF levels in the serum of both groups. Cytokine production assessed by pokeweed mitogen-stimulated spleen condition medium showed an age-related decline. Androgen treatment could not influence IL-3 and GM-CSF production of spleen. These findings suggest that the spleen of both old and young mice served as the major site of regenerative repopulation of hemopoietic progenitors, especially the late erythroid progenitors in 19-ND-treated mice. The proliferative reserve of erythropoiesis with androgen treatment in aged mice was not reduced more than that in treated-young mice.

Abstract
A 64-year-old woman had been given a diagnosis of Ph-positive chronic myelogenous leukemia (Ph+ CML) in October 1992 and accordingly treated with interferon-alpha busulfan, and hydroxyurea. She was admitted to our hospital with a one-day history of consciousness disturbance on May 30, 1993. Two weeks before admission, she had received chemotherapy consisting of vincristine and predonisolone because of progressive thrombocytopenia, basophilia, and leukocytosis accompanied by a heightened degree of cell immaturity in peripheral blood and bone marrow. Cranial computerized tomography on admission disclosed tumoral masses in the left frontal lobe and the right temporal lobe. Moreover, lumbar puncture ezinkns disclosed blastoid cells in cerebrospinal fluid. Based on these laboratory findings, the diagnosis was blastic crisis CML, 46XX t(9; 22; 17) (q34; q11; q23), cytogenetic aberration and extramedulary brain disease Although the patient underwent the same combined chemotherapy again, her unconsciousness did not resolve. She died of cerebellar herniation on the 7th hospital day. Post mortem examination revealed three extramedullary tumors localized in cranial dura. This was a rare case of CML presenting multiple extramedullary tumors localized in cranial dura.

Abstract
Among recent clinical isolates in Japan, strain CU264 was discovered which formed unusual colonies. This strain was identified as Rahnella aquatilis which is usually found in water. The antibiotic susceptibilities against tetracycline, carbenicillin, chloramphenicol, streptomycin, kanamycin, gentamicin, sulphonamide, neomycin, fosfomycin, rifampicin, norfloxacin and nalidixic acid, were investigated. The result demonstrated that the strain was highly resistant to fosfomycin only. It was further shown that this resistance was transmissible with low frequency to Serratia marcescens whereas it was not transmissible to Escherichia coli.

Abstract
Constitutive expression of human colony-stimulating factor-1 receptor (CSF-1R) confers long-lasting CSF-1-dependent proliferation to mouse myeloid cell lines. We developed mice transgenic for human CSF-1R because mouse CSF-1 cannot activate human CSF-1R. Then bone marrow cells from transgenic mice were plated onto MS-5 stromal cells expressing the membrane form of human CSF-1 (2M-1 cells) in order to combine the hematopoietic supporting properties of stromal cells and the proliferative effects of CSF-1. Thus, we were able to derive a hematopoietic cell line, called 47.10, that grew indefinitely under these conditions, whereas no cell line could be developed from nontransgenic mice. Proliferation of 47.10 cells is severely affected by neutralizing anti-CSF-1R monoclonal antibodies. Morphologic and cytofluorometry analysis established that most 47.10 cells are immature myelomonocytic cells. Consistent with this phenotype, the myeloid transcription factor PU.1, but not the erythroid transcription factor GATA-1, is expressed in 47.10 cells. A few 47.10 cells (3-5%) do not express lineage specific markers; they differentiate spontaneously to lineage-positive cells after replating on 2M-1 cells. In agar cultures, 47.10 cells form 7- and 14-day colonies in response to a cocktail of granulocyte/macrophage colony-stimulating factor (2.5 ng/mL), interleukin-3 (1 ng/mL), and mouse CSF-1 (10 ng/mL). Under these conditions, about 0.5% of 47.10 cells formed large 14-day colonies (>1 mm) composed of mature monocytes and granulocytes, reflecting the presence of progenitors endowed with high proliferative potential (HPP-47.10 cells). In conclusion, we have characterized a novel continuous myeloid cell line presenting a hierarchical structure similar to that of the bone marrow progenitor cell compartment.

Abstract
It is generally accepted that the nonsteroidal anti-inflammatory drugs (NSAIDs) exhibit anti-inflammatory effects primarily through inhibition of prostaglandin (PG) synthesis. However, effects of NSAIDs on immune responses are not fully understood. This study investigated effects of indomethacin and a new NSAID (d-2-[4-(3-methyl-2-thienyl)phenyl]propionic acid, termed as M-5011 in this study) on cytokine production, lymphocyte proliferation, activities of natural killer (NK) and lymphokine activated killer (LAK) cells and secretion of immunoglobulin (Ig). Both indomethacin and M-5011 augmented interleukin (IL)-2 production, whereas they suppressed IL-6 production both at the protein and mRNA levels. These two NSAIDs augmented proliferation of phytohemagglutinin (PHA)-stimulated PBMC and enhanced NK and LAK cell activities. In contrast, indomethacin was more potent than M-5011 in inhibition of both PG synthesis and Ig secretions by pokeweed mitogen (PWM)-stimulated PBMC. These results suggest that these two NSAIDs equally augment cell-mediated immunity, whereas indomethacin was more potent than M-5011 in the inhibition of humoral immunity and PG synthesis.

Abstract
A 16-year-old girl was admitted for a detailed examination of hemolytic anemia in November 1995. Initial laboratory findings included a total bilirubin concentration of 1.46 mg/dl, hemoglobin of 9.1 g/dl, and a reticulocyte count of 89/1000 percent. The plasma haptoglobin concentration was below 10 mg/dl. A blood smear showed many dacryocytes and a few echinocytes and codocytes. GOT was 71 IU/l; GPT, 44 IU/l; and LDH, 812 IU/l; the results of a hepaplastin test were 45% of normal. On further investigation, the level of serum ceruloplasmin was found to be 4 mg/dl, and of serum copper, 43 micrograms/dl. Urinary copper excretion was markedly increased, at 345 micrograms per day. Slit-lamp examination of both corneas revealed obvious Kayser-Fleischer rings. A liver biopsy sample showed fibrosis histologically and an elevated copper concentration of 535 micrograms/g dry weight and 183 micrograms/g wet weight. In family studies, the patient's asymptomatic 5-year-old sister was observed to have metabolic abnormalities consistent with Wilson's disease. These findings suggested that the patient's hemolytic anemia with red cell deformities was due to abnormal copper metabolism associated with Wilson's disease.

Abstract
A 30-year-old man who had been given a diagnosis of IgG-kappa multiple myeloma by another hospital and treated with melphalan, prednisone, and cyclophosphamide 6 months earlier, was admitted to our hospitaly in July 1994 because of progressively impaired hearing in both ears, vertigo, and worsening fatigue. Peripheral blood examination showed a white blood cell count 25,000/microliter, with 77.5% atypical plasma cells. Examination at the time of hospitalization also revealed retinal hemorrhages and serum hyperviscosity. The diagnosis was plasma cell leukemia with hyperviscosity syndrome. Subsequent treatment consisted of vincristine, doxorubicine, and prednisone and repeated plasmapheresis. This resulted in a partial response and a reduction of serum viscosity but no reversal of hearing loss. One month after admission, left sixth cranial nerve plasy was demonstrated. Cranial computed tomography studies disclosed a tumoral mass in the sphenoid sinus. The patient received local radiotherapy and intensive chemotherapy, but exhibited no notable alleviation of his cranial nerve palsy. He died of septicemia and progressive disease in August 1994. This case was rare in that it involved plasma cell leukemia and bilateral neurosensory hearing loss associated with serum hyperviscosity and sixth cranial nerve plasy due to plasmacytoma within the sphenoid sinus.

Abstract
The present study was designed to investigate the in vitro effects of potential therapeutic agents on cytokine production by five HTVL-I-infected T cell clones (TCC) established from the ocular fluid of patients with HTLV-I uveitis. Each of the five HTLV-I-infected TCC was cultured at 1 x 10(6) cells/ml with or without an immunosuppressive agent (hydrocortisone, FK506, rapamycin, indomethacin, or prostaglandin E2) for 22 hr in humidified 5% CO2 in air at 37 C. The production of various cytokines in the culture supernatant from each TCC was measured by ELISA. The HTLV-I-infected TCC produced high amounts of IL-1 alpha, IL-3, IL-6, IL-8, TNF-alpha, IFN-gamma, and GM-CSF, and low but significant levels of IL-2 and IL-10 without any stimuli. Hydrocortisone severely depressed the production by these TCC of all the cytokines except for IL-2, which was slightly increased. Prostaglandin E2 depressed the production of IL-1 alpha, while it up-regulated the production of IL-6, TNF-alpha, and IFN-gamma. Rapamycin depressed the production of IL-6 and TNF-alpha, and FK506 depressed the production of TNF-alpha. Hydrocortisone also severely depressed the cytokine production by PHA-stimulated peripheral blood mononuclear cells obtained from healthy volunteers. Of the immunosuppressive agents tested, hydrocortisone exhibited the strongest suppression of cytokine production by HTLV-I-infected TCC. This result was in agreement with the in vivo effects of hydrocortisone in patients with HTLV-I uveitis. These TCC will be useful in investigating the effects of potential therapeutic agents for HTLV-I uveitis in vitro.

Abstract
Among glycosaminoglycans, dermatan sulfate (DS) is the strongest inhibitor of DNA synthesis in adult rat hepatocytes in primary culture stimulated with insulin and epidermal growth factor. Hyaluronate also inhibited DNA synthesis, whereas chondroitin-6 sulfate, 4-sulfate or heparin had no effect on DNA synthesis in hepatocytes. Analysis of growth regulatory factors in hepatocyte culture medium treated with DS revealed that interleukin-1 (IL-1) was released into the medium. IL-1 beta mRNA was detected in DS-treated hepatocytes by reverse transcriptase-polymerase chain reaction, but not in untreated hepatocytes. For a marked inhibition of DNA synthesis, more than 10 hr of exposure to DS before cultured hepatocytes started DNA synthesis, was required. Similarly, more than 10 hr was required after the addition of DS before IL-1 beta mRNA was detected. These findings suggest that DS in the medium induced the production of IL-1 beta which, in turn, reduced DNA synthesis in hepatocytes.

Abstract
In serum, the enzyme adenosine deaminase (ADA) is known to be divided into two isoenzymes, ADA1 and ADA2, which have different molecular weights and kinetic properties. The present study investigated ADA isoenzyme levels in the sera of patients infected with retroviruses associated with adult T-cell leukemia (ATL), human T-cell lymphotropic virus type 1 (HTLV-1)-associated myelopathy (HAM), and AIDS, ADA isoenzyme activities were found to be significantly (P < 0.001) higher in the sera of patients with ATL, HAM, and AIDS than in the sera of healthy controls. In the case of the ADA subtypes in the sera of patients with ATL, ADA1 activity was significantly (P < 0.001) elevated in patients with the acute and lymphoma types of ATL compared with that in patients with the chronic and smoldering types of ATL. ADA2 activity was significantly elevated in the sera of patients with the acute, lymphoma, and chronic types of ATL (P < 0.001) compared with that in patients with smoldering ATL and HTLV-1 carriers. In the case of patients with human immunodeficiency virus type 1 (HIV-1) infection, ADA1 and ADA2 activities in the sera of patients with AIDS and HIV-1 antibody-positive individuals were significantly (P < 0.001) higher than those in the sera of HIV-1 antibody-negative individuals. A significant elevation in ADA2 activity was also seen in the sera of AIDS patients (P < 0.01) compared with that in the sera of HIV-1 antibody-positive individuals. These results suggest that the magnitude of elevation of ADA isoenzyme levels in serum correlates well with the clinical conditions of the patients with these diseases. Measurement of the activities of ADA isoenzymes may therefore provide an additional parameter for distinguishing the subtypes of ATL and may prove to be useful as prognostic and therapeutic monitors in diseases associated with HTLV-1 and HIV-1 infections.

Abstract
Two patients with relapsed Non-Hodgkin's lymphoma (NHL) were treated with oral administration of etoposide. In these patients, long-term hematological remission was obtained. One patient was a 76-year-old man, who was successfully treated with CHOP for diffuse large cell NHL stage III B. One year after obtaining CR, he was admitted to our hospital for enlargement of lymph node. Rebiopsy of lymph node made a diagnosis of relapse from NHL. A new regimen of oral administration of etoposide treatment was employed. Hematological remission was obtained and continued for 3 years. Without interfering with his quality of life. The other patient was a 74-year-old man, who was treated with 6 cycles of CHOP for diffuse large cell NHL stage IV B. The patient attained complete remission following an additional 2 cycles of COMLA therapy. Eight years later, he was admitted for enlargement of lymph node. Rebiopsy of lymph node provided the basis for a diagnosis of relapse from NHL. Oral administration of etoposide treatment was started. Hematological remission was obtained and has been continued until now. These results show that oral administration of etoposide treatment is effective for some patients with recurrent NHL.

Abstract
Nonsteroidal anti-inflammatory drugs (NSAIDs) are well known as immunoregulators, but the mechanisms of their action are not fully explained by the inhibition of PG synthesis. We have investigated the effect of NSAIDs on cytokine production in human PBMC and T cell clones (TCC). NSAIDs up-regulated TNF, IFN-gamma and IL-2 production at both the mRNA and protein levels, and IL-12 expression at the mRNA level. In contrast, NSAIDs down-regulated IL-6 production both at the mRNA and protein levels, and down-regulated IL-4 mRNA expression. The modulation at the mRNA level became detectable 1 h after culture. This modulation was also observed at the level of TCC. Indomethacin (IM) enhanced TNF production in all the eight TCC that were established from a patient with human T lymphotrophic virus type 1 uveitis or pulmonary sarcoidosis, and suppressed IL-6 production in six of the eight TCC, without affecting their low levels of PGE2 production. IM also enhanced TNF and suppressed IL-6 production, respectively, in both IL-2-activated PBMC and IL-2-dependent NK cell line, with the inhibition of their high levels of PGE2 production. Culture with PGE2 alone suppressed TNF production by three of the six TCC and NK cell lines, which was neutralized by addition of IM. It had, however, no effect on TNF production by the remaining three TCC or IL-2-activated PBMC. The effects of PGE2 on IL-6 production also varied among TCC.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A case of NHL which has been in long-term remission following vigorous treatment for CNS relapse with intrathecal administration of Ara-C and focal irradiation to the brain is presented. The patient was a 61-year-old man, who was successfully treated with CHOP followed by MACOP-B for diffuse large cell NHL in 1988. Five months later he was admitted to our hospital because of loss of visual acquity and numbness in the right upper and lower extremities. The presence of lymphoma cells in CSF, abnormal shadow in the left frontal lobe on a cranial CT scan and MRI scan, and positive Ga scintigraphy yielded a diagnosis of CNS relapse of NHL. Twenty one whole brain and additional 1.0Gy to the left frontal lobe of irradiation were performed. Eight days later the left tumor disappeared. Neurological remission was obtained and has continued until now.
