Abstract
Objectives This study aimed to evaluate the cumulative incidence of upper tract urothelial carcinoma (UTUC) recurrence and identify its risk factors in patients who underwent radical cystectomy (RC). Patients and methods We performed RC on 385 patients between September 2002 and February 2020. After excluding 20 patients-13 with simultaneous nephroureterectomy, 6 with distal ureteral stump positivity and 1 with urachal cancer-365 patients were included in the analysis. To predict UTUC recurrence, we examined the cancer extension pattern in cystectomy specimens and categorized them into three types: cancer located only in the bladder (bladder-only type), cancer extending to the urethra or distal ureter (one-extension type) and cancer extending to both the urethra and distal ureter (both-extension type). We determined hazard ratios for UTUC recurrence for each covariate, including this cancer extension pattern. Results Of the 365 patients, 60% had the bladder-only type, 30% had the one-extension type and 10% had the both-extension type. During a median follow-up period of 72 months for survivors, UTUC recurred in 25 of the 365 patients, with cumulative incidences of 3.7% at 5 years and 8.3% at 10 years. The median interval from cystectomy to recurrence was 65 months (interquartile range: 36-92 months). In the multivariate analysis, the extension pattern was a significant predictor of UTUC recurrence. The hazard ratios for UTUC recurrence were 3.12 (95% confidence interval [CI] = 1.15-8.43, p = 0.025) for the one-extension type and 5.96 (95% CI = 1.98-17.91, p = 0.001) for the both-extension type compared with the bladder-only type. Conclusions The cancer extension pattern in cystectomy specimens is predictive of UTUC recurrence. A more extensive cancer extension in cystectomy specimens elevates the risk of subsequent UTUC recurrence. Intensive long-term monitoring is essential, particularly for patients with the both-extension type.

Abstract
OBJECTIVES We investigated the clinical outcomes of radical cystectomy without cisplatin-based neoadjuvant chemotherapy (NAC) and identified factors affecting the effectiveness of cisplatin-based adjuvant chemotherapy (AC). METHODS Between September 2002 and February 2020, 288 bladder cancer patients who did not receive NAC underwent radical cystectomy. We retrospectively analyzed the recurrence rates, primary recurrence sites, recurrence-free survival (RFS), and overall survival (OS) of 115 advanced bladder cancer patients (pT3-4 or pN1-3) who were divided into the AC and observation groups. Subgroup analysis was performed, focusing on pathological stage. RESULTS In total, 51 patients received AC, and 64 patients were observed. The median follow-up duration was 95 months. The recurrence rate was lower in the AC group than in the observation group (35.3% vs. 54.7%, p = 0.041). The rate of recurrences in the lymph node area (dissection site and proximal lymph nodes) was lower in the AC group (9.8% vs. 26.6%; p = 0.031). In the subgroup analysis of patients with pN1, the probability of RFS and OS was higher in the AC group than in the observation group. The hazard ratio for RFS and OS was 0.243 (95% confidence interval [CI]: 0.077-0.768) and 0.259 (95% CI: 0.082-0.816), respectively. The 5-year RFS and OS were significantly higher in the AC group (80.0% and 79.4%) than in the observation group (35.7% and 42.9%; p < 0.008 and p < 0.012, respectively). CONCLUSIONS AC improved RFS and OS in patients with pN1 disease who did not receive NAC and should be considered for this population.

Abstract
Testicular epidermoid cysts have characteristic findings. Testicular tumor markers are negative in patients with epidermoid cysts. Clear margins and sole and small testicular tumors (20 mm or less) suggest the possibility of epidermoid cyst. Testicular-sparing surgery with intraoperative frozen section examination should be performed when suspecting epidermoid cysts. Testicular epidermoid cysts are rare tumors that account for 1% of all testicular tumors and are often clinically misdiagnosed as malignant lesions. We report three cases of epidermoid cysts. The chief manifestations were scrotal induration in two patients and pruritus scrotum in one. The median age of the patients was 23 years (18-30). All tumors were determined to be sole lesions (<20 mm in diameter). Testing for tumor markers in all patients revealed negative results. We could not rule out malignancy; hence, we performed high inguinal orchiectomy in all cases. Histologically, the inner walls of the cysts were lined with stratified squamous epithelium; their contents were keratinized. All patients were diagnosed with epidermoid cysts.

Abstract
1. This study elucidated the last-male sperm precedence (LMSP) mechanism in chickens by examining replacement in storage tubules (SSTs) after multiple artificial inseminations (AI) and the effects of seminal plasma (SP) and male breed on sperm replacement in SSTs.2. Hens were artificially inseminated with fluorescent dye-labelled spermatozoa from White Leghorn (WL) chickens. Secondary AI was conducted 3 d later with sperm labelled with different nuclear fluorescent dye. Percentage of first and second inseminated sperm in SSTs and their logarithmic odds were calculated. The effect of SP on LMSP was examined using (1) Lake's solution-washed sperm before second insemination, and (2) SP injected continuously after first insemination. Effect of breed difference on sperm replacement was investigated using Barred Plymouth Rock (BP) sperm.3. Successive WL-sperm inseminations at three-day intervals caused > 70% stored sperm replacement in SSTs. Although SP removal from sperm from second insemination significantly decreased replacement, its intra-vaginal injection did not affect release. Secondary insemination using BP sperm significantly increased replacement.4. Sperm replacement is a major factor favouring LMSP in domestic chickens. Two fluorescent staining of sperm, and intra-vaginal multiple AI technique have enabled visualisation, differentiation, and quantification of multiple inseminated sperm stored in the SSTs.

Abstract
OBJECTIVES To determine the incidence and location of lower extremity deep vein thrombosis in patients undergoing radical cystectomy. METHODS We performed radical cystectomy in 137 patients with bladder cancer between August 2014 and February 2020. Since 2014, we have had a policy to screen for deep vein thrombosis using lower extremity ultrasonography both before and after radical cystectomy. We determined the incidence and location of deep vein thrombosis and classified it as either proximal or distal type. Furthermore, we explored the incidence of pulmonary embolism within 3 months after radical cystectomy. RESULTS After excluding six patients with a lack of ultrasonographic data, we evaluated 131 patients. Preoperative deep vein thrombosis (one proximal and 17 distal) was diagnosed in 18 patients (14%) with no symptoms. Postoperative deep vein thrombosis was diagnosed in 41 patients (31%; three proximal and 38 distal), of whom 26 (63%) had new-onset deep vein thrombosis after cystectomy. Three patients, two with proximal and one with distal type deep vein thrombosis, developed nonfatal pulmonary embolism postoperatively. Multivariate analysis showed that preoperative D-dimer levels (odds ratio 5.35, 95% confidence interval 1.74-16.50; P < 0.003), type of urinary diversion (ileal neobladder; odds ratio 11.15, 95% confidence interval 2.16-57.55; P = 0.004), and preoperative deep vein thrombosis (odds ratio 15.93, 95% confidence interval 3.82-66.30; P < 0.001) were significant risk factors for postoperative deep vein thrombosis. CONCLUSIONS Pre- and post-radical cystectomy whole-leg ultrasonography can lead to an early perioperative diagnosis and immediate treatment of proximal deep vein thrombosis, thereby potentially preventing fatal pulmonary embolism.

Abstract
(Objectives) We evaluated the association between immune-related adverse events (irAEs) and the efficacy of pembrolizumab therapy in patients with metastatic urothelial carcinoma. (Methods) Data of 42 patients with metastatic urothelial carcinoma treated with pembrolizumab between May 2018 and February 2020 were retrospectively analyzed to determine the association between irAEs and objective response rate (ORR), progression-free survival (PFS), and overall survival (OS). (Results) IrAEs were observed in 19 patients (45.2%). Objective response was observed in 15 patients (35.7%). Thirteen (68.4%) of 19 patients who experienced irAEs showed an objective response, whereas two (8.70%) of 23 patients who did not experience irAEs (odds ratio: 15.0, 95% confidence interval [CI]: 1.70-738, P=0.006). PFS and OS in the irAE group were longer than those in the non-irAE group (PFS: hazard ratio: 0.24, 95% CI: 0.11-0.54, P<0.001; OS: hazard ratio: 0.11, 95% CI: 0.03-0.37, P<0.001). (Conclusions) During pembrolizumab treatment, the occurrence of irAEs was significantly associated with higher response and survival prolongation in patients with metastatic urothelial carcinoma.

Abstract
Abstract
Background
The relation between very low on-treatment low-density lipoprotein cholesterol (LDL-C) level and the cardiovascular event risk is still unclear in patients receiving the same doses of statins.
Methods
From the REAL-CAD study comparing high-dose with low-dose pitavastatin therapy in Japanese patients with stable coronary artery disease, 11105 patients without reported non-adherence for the study drug were divided into 3 groups according to the on-treatment LDL-C level at 6-month (<70 mg/dL, 70–100 mg/dL, and ≥100 mg/dL; N=1016, N=3078, and N=1665 in the pitavastatin 1 mg/day stratum; N=2431, N=2524, and N=391 in the pitavastatin 4 mg/day stratum). Primary outcome measure was a composite of cardiovascular death, non-fatal myocardial infarction, non-fatal ischemic stroke, or unstable angina requiring emergent admission.
Results
In the pitavastatin 1 mg/day stratum, cumulative 4-year incidence of the primary outcome measure was not significantly different across the 3 groups (5.0%, 5.7%, and 5.2%, P=0.51), while in the 4 mg/day stratum, it was significantly higher in the LDL-C ≥100 mg/dL group than in other groups (4.5%, 3.4%, and 9.1%, P<0.001). The adjusted risks of the LDL-C <70 mg/dL group relative to the LDL-C 70–100 mg/dL group (reference) remained insignificant for the primary outcome measure in both 1 mg/day and 4 mg/day strata (HR 0.84, 95% CI 0.58–1.18, P=0.32, and HR 1.25, 95% CI 0.88–1.79, P=0.22). The adjusted risk of LDL-C ≥100 mg/dL group relative to the reference group was not significant for the primary outcome measure in the 1 mg/day stratum (HR 0.82, 95% CI 0.60–1.11, P=0.21), while it was highly significant in the 4 mg/day stratum (HR 3.32, 95% CI 2.08–5.17, P<0.001). In the on-treatment LDL-C ≥100 mg/dL group in the 4 mg/day stratum, LDL-C increased by 6.3 mg/dL from baseline to 6-month despite dose escalation of pitavastatin from 1 mg/day to 4 mg/day, suggesting the presence of unreported poor adherence in this small subgroup.
Adjusted Effects of On-treatment LDL-C
Conclusions
Very low on-treatment LDL-C level (<70 mg/dL) was not associated with lower cardiovascular event risk compared with moderately low on-treatment LDL-C level (70–100 mg/dL) in patients receiving the same doses of statins. Too much emphasis on the target LDL-C strategy might mislead the clinical practice.

Abstract
IgG4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory disorder that can occur in almost all systemic organs and generally responds to corticosteroid treatment. We report a rare case of an IgG4-related intrapelvic mass lesion that responded to steroid therapy but caused a fistula between the sigmoid colon and bladder. A 71-year-old man was followed after treatment for hepatocellular carcinoma. Follow-up computed tomography (CT) incidentally depicted left hydronephrosis with an ill-demarcated intrapelvic mass lesion. This lesion was histologically diagnosed as IgG4-RD by open biopsy, and peroral steroid therapy was initiated. One month after starting steroids, a colovesical fistula was detected by follow-up CT. A colostomy and urethral catheterization were emergently performed. The patient recovered and the mass lesion was drastically minimized by the initiation of glucocorticoids; however, he still needs urethral catheterization. IgG4-RD develops in various systemic organs and generally responds well to steroids. Clinicians must be watchful for the complications of responses to corticosteroids, such as fistulization, when the mass lesion of IgG4-RD is adjacent to multiple luminal organs.

Abstract
In January 2005, a 66-year-old man underwent radical cystectomy and ileal neobladder reconstruction for invasive bladder cancer. A total of 3 years after the cystectomy, left-side ureteral cancer was diagnosed, and a nephroureterectomy was carried out in May 2008. In October 2011, he complained of asymptomatic macroscopic hematuria. We detected multiple papillary pedunculated and broad-based tumors in the left side and the dome of the neobladder. The patient underwent transurethral resection of the bladder tumor, and a pathological diagnosis of high-grade pTa urothelial carcinoma was made. A total of 4 months later, tumors recurred in the right side and anterior wall of the neobladder. We carried out transurethral resection of the bladder tumor again; the pathological diagnosis was high-grade pTa urothelial carcinoma with carcinoma in situ. Bacillus Calmette-Guérin instillation was carried out seven times into the neobladder, without any severe side-effects. Tumor recurrence was not observed up to 8 months after bacillus Calmette-Guérin treatment.

Abstract
Mitochondria-cytoskeleton interactions were studied in the hamster embryos during interphase and M phase of the cell cycle. Two-cell embryos were cultured for 1 h with nocodazole, cytochalasin D or in a combination of both inhibitors and then centrifuged at 10,000 × g for 2 min. The control embryos were only centrifuged with no inhibitor treatment. Centrifuged embryos were fluorescently stained to examine the distribution of active mitochondria and nuclear configuration. In the control 2-cell embryos, most mitochondria were accumulated at the perinuclear region with some at the cell cortex. Neither each inhibitor nor centrifugation did affect the distribution of mitochondria in interphase blastomeres. However, mitochondria were spun down towards the centrifugal pole in 71% (n = 41) of the interphase blastomeres treated with centrifugation following a combination of nocodazole plus cytochalasin D, suggesting that both microtubules and microfilaments may involve in mitochondrial redistribution during interphase of the cell cycle. In contrast, when M-phase blastomeres were treated with all drug treatments applied, including cytochalasin D, mitochondria had been usually dislocated in a unipolar cluster, suggesting that microfilaments, not microtubules, may involve in the mitochondrial redistribution during M phase of the cell cycle. The data indicate that microfilaments function in mitochondrial redistribution regardless of the stages of the cell cycle and that microtubules may strongly associate with mitochondria during the interphase but dissociate from them during the M phase.

Abstract
An 83-year-old woman was referred to our emergency department with acute urticaria and sudden shortness of breath approximately 30 min after taking rectal diclofenac potassium for lumbago. After treatment with adrenaline and corticosteroids, the patient became hemodynamically stable and left the hospital on the next day. She attended our hospital 1 week after the onset of anaphylaxis because of repeated postprandial epigastric pain. No abnormal lesions were found in endoscopy. Radiographic selective catheter angiography revealed chronic mesenteric ischemia caused by atherosclerosis and abundant collateral arteries between the celiac trunk, the superior mesenteric artery and the inferior mesenteric artery. Patients with chronic mesenteric ischemia usually present with a clinical syndrome characterized by painful abdominal cramps and colic occurring typically during the postprandial phase. Fear of eating resulted in malnutrition. She was prescribed proton pump inhibitor, digestants, anticholinergic agents, serine protease inhibitors, prokinetics, antiplatelet agents and transdermal nitroglycerin intermittently, but these had no beneficial effects. It was most probable that this patient with chronic atherosclerotic mesenteric ischemia was suffering from functional abdominal pain syndrome induced by anaphylaxis. Since psychiatric disorders were associated with alterations in the processing of visceral sensation, we facilitated the patient's understanding of functional abdominal pain syndrome with the psychologist. Postprandial abdominal pain gradually faded after administration of these drugs and the patient left the hospital. Developing a satisfactory patient-physician relationship was considered more effective for the management of persistent abdominal pain caused by complicated mechanisms.

Abstract
Oxytocin (OT) levels in plasma increase during sexual response and are significantly lower in patients with depression. A drug for the treatment of sexual dysfunction, sildenafil, enhances the electrically evoked release of OT from the posterior pituitary. In this study, we showed that sildenafil had an antidepressant-like effect through activation of an OT signaling pathway. Application of sildenafil reduced depression-related behavior in male mice. The antidepressant-like effect was blocked by an OT receptor (OTR) antagonist and was absent in OTR knockout (KO) mice. Sildenafil increased the phosphorylation of cAMP response element-binding protein (CREB) in the hippocampus. The OTR antagonist inhibited sildenafil-induced CREB phosphorylation and sildenafil had no effect on CREB phosphorylation in OTR KO mice. These results suggest sildenafil to have an antidepressant-like effect through the activation of OT signaling and to be a promising drug for the treatment of depression.

Abstract
To improve culture system for in vitro maturation (IVM) of porcine oocytes, ghrelin, leptin or growth hormone (GH), at concentration of 0, 0.5, 5, 50 and 500 ng/ml were added to the porcine follicular fluid (pFF)-supplemented medium NCSU23, and their effects on the maturation and cytoskeletal distribution of the oocytes with or without cumulus cells were compared. In the cumulus-denuded oocytes, no significant changes were noted in the maturation rate by different hormone treatments due to a marked decline in the controls. Maturation of the cumulus intact oocytes was moderately interfered by ghrelin (0.5-50 ng/ml, p < 0.01), but not significantly affected by leptin and GH. Distribution density of the cytoplasmic microtubules was decreased significantly by addition of ghrelin (by approximately 30% in 50-500 ng/ml, p < 0.01), whereas no remarkable effect was noted by leptin supplementation. High concentration (500 ng/ml) of ghrelin or leptin decreased significantly the cytoplasmic microfilaments in density (by 43% and 38%, p < 0.01, respectively). GH did not affect cytoskeletal distribution. The results suggest, in the culture system using pFF-supplemented medium that (i) ghrelin may have some inhibitory effect on the organization of microtubules and microfilaments, probably being a factor in lowered maturation rate and (ii) the addition of higher concentration of leptin may decrease microfilaments in density with no effect on meiotic maturation of the porcine oocytes.

Abstract
An electron microscopic study revealed disruption of capillary endothelial tight junctions (TJs) in both biopsied muscle, taken at 5 years and 1 month of age, and the autopsied brain, taken at 13 years and 6 months of age, in a patient with mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS) and mitochondrial DNA (mtDNA) point mutation A3243G. This endothelial barrier disruption might result in vasogenic edema and systemic lactic acidosis, possibly the critical pathology of MELAS.

Abstract
A 23-year-old female with hypoglossia, who had a narrow mandibular dental arch, was treated using the gradual expansion technique. Three lower incisors were missing and the right molar occlusion showed a scissor bite. Her speech was acceptable. Gradual unilateral expansion of the mandibular alveolar bone was performed. Orthodontic tooth alignment was performed prior to surgical treatment. A tooth-borne expander was devised using a hyrax-type screw to move the inclined right alveolar bone into an upright position. Alveolar bone osteotomies were performed under general anesthesia and the expander was placed in the mandibular dental arch. After a 5-day latency period, the screw was activated for 21 days. After expansion, the width of the mandibular dental arch increased by 10mm at the first molar region and the right molars were moved to an upright position. After a consolidation period of 7 days, simultaneous two-jaw surgery that combined Le Fort I osteotomy and intraoral vertical ramus osteotomies was performed to obtain a stable occlusion. After post-surgical orthodontic and prosthodontic treatment, her occlusion improved without deterioration of her speech. The results indicate that this technique is useful for unilateral expansion of distorted mandibular alveolar process.

Abstract
Uterine blood flow (UtBF) is a major regulator of transplacental fetal nutrient supply. The aim was to serially measure uterine blood flow from mid to late pregnancy in a paradigm of relatively late onset placental and fetal growth restriction. Singleton bearing adolescent dams was fed high (H) or control (C) nutrient intakes to induce putatively compromised or normal pregnancies, respectively. A perivascular flow probe was attached to the uterine artery of the gravid horn on Day 83 of gestation and UtBF was then recorded continuously for 2h, three times weekly until approximately Day 135, when pregnancies were either terminated or ewes allowed to deliver at term (approximately Day 145). Pregnancy outcome was determined at term in contemporaneous ewes without UtBF assessment. Placental and fetal weights were lower (P<0.001) in H compared with C intake groups and were independent of flow probe surgery and monitoring. Uterine blood flow was lower in H compared with C groups at the first assessment (Day 88, P<0.001) and was positively correlated with adjusted fetal weight at term, irrespective of treatment group (P<0.01). UtBF increased throughout the second half of gestation in both groups. Linear regression analysis of UtBF against day of gestation revealed that the slope was equivalent (5.5 vs. 5.3ml/min per day) and the mean intercept lower (212 vs. 370ml/min, P<0.001) in H compared with C groups, respectively. This study demonstrates the feasibility of serially measuring UtBF within the same individual sheep for a protracted period during the second half of gestation. UtBF was already lower at mid gestation in putatively growth restricted compared with control pregnancies, ahead of any reduction in placental and fetal weight, but increased similarly during the second half of gestation in both groups. These data are commensurate with the reported decrease in placental angiogenic growth factor expression at mid gestation, and, indicate that attenuated UtBF is an early defect in this adolescent paradigm.

Abstract
To permit rapid optical control of brain activity, we have engineered multiple lines of transgenic mice that express the light-activated cation channel Channelrhodopsin-2 (ChR2) in subsets of neurons. Illumination of ChR2-positive neurons in brain slices produced photocurrents that generated action potentials within milliseconds and with precisely timed latencies. The number of light-evoked action potentials could be controlled by varying either the amplitude or duration of illumination. Furthermore, the frequency of light-evoked action potentials could be precisely controlled up to 30 Hz. Photostimulation also could evoke synaptic transmission between neurons, and, by scanning with a small laser light spot, we were able to map the spatial distribution of synaptic circuits connecting neurons within living cerebral cortex. We conclude that ChR2 is a genetically based photostimulation technology that permits analysis of neural circuits with high spatial and temporal resolution in transgenic mammals.

Abstract
With the widespread use of imaging modalities, incidentally discovered small renal cell carcinomas have increased. Some patients, however, are too old or weak due to various diseases to undergo surgery and other patients occasionally refuse surgery. To investigate the natural history of small renal cell carcinoma, we retrospectively reviewed patients with small renal tumors suggestive of carcinoma. We retrospectively reviewed 15 patients with contrast-enhancing renal masses less than 4.0 cm in diameter who were observed without treatment. The mean follow-up period was 38 months (range, 8-91). The average patient age was 67 years (range, 44-87). The initial average tumor diameter was 2.2 cm (range, 1.0-3.9). The average growth rate was 0.06 cm per year (range, -0.09-0.28). Only 4 tumors grew obviously during the follow-up period. Three tumors were removed surgically by radical nephrectomy, and all tumors were pathologically diagnosed as renal cell carcinoma. None of the patients developed metastases during the follow-up period or after surgery. Two patients died of other causes. Nonsurgical watchful waiting may be an acceptable treatment option for elderly or severely comorbid patients; however, it is not known whether this conservative management can be applied to young or otherwise healthy patients.

Abstract
During early development, mitochondrial distribution in the ooplasm is dramatically changed. In mice and pigs, it has been reported that translocation of mitochondria is mediated by microtubules, but not by microfilaments. However, the study using hamster embryos suggested that microfilaments played a role in the mitochondrial distribution. In this study, the role of microtubules and microfilaments on distribution of mitochondria was evaluated in 2-cell hamster embryos. Female golden hamsters were superovulated on the day of post-estrus discharge by PMSG in a weight-dependent manner [Mackiernan and Bavister 2000 Hum. Reprod. 15, 157–164], and mated with males in the evening 3 days later. Two-cell embryos were collected from the oviducts at 0900–1000 on Day 2 of pregnancy. Embryos were cultured in HECM-10 medium with or without nocodazole (a microtubule assembly inhibitor), and/or cytochalasin D (a microfilament assembly inhibitor) for 8–10 h in a humidified atmosphere of 10% CO2, 5% O2, and 85% N2 at 37.5°C. After incubation of embryos with or without inhibitors, mitochondria were stained with rhodamine 123. Some of them were stained for microtubules, microfilaments, and DNA, as reported previously (Suzuki et al. 1999 Biol. Reprod. 61, 521–526). In 2-cell hamster embryos (controls, n = 44), most mitochondria were accumulated at the perinuclear region, while little mitochondria were noted in the cell cortex. Microtubules were found around the nuclei, and distribution of the mitochondria was somewhat correlated with that of the microtubules. In contrast, microfilaments were located in a high density just under the cell membrane. After nocodazole treatment (n = 22), mitochondria had extended into the subcortical (intermediate) region in various degrees, where mitochondria were aggregated into large masses. After cytochalasin D treatment (n = 17), distributional density of mitochondria at the peripheral region was decreased, and mitochondria moved back around the nucleus. After treatment by both inhibitors (n = 21), a distribution pattern of mitochondria was almost similar to that observed after cytochalasin D treatment. The present results suggest that the distribution of mitochondria at the perinuclear region is mediated by microtubules, whereas the movement of mitochondria to the cell cortex is regulated by microfilaments. Microfilaments seemed to play a role as the anchor of mitochondria at the cell cortex.

Abstract
A 2-stage procedure combining maxillary advancement by distraction technique with mandibular setback surgery was used to correct jaw deformities in 5 patients with severe maxillary retrusion secondary to cleft lip and palate. First, a Le Fort I maxillary osteotomy was performed. Immediately after maxillary distraction, the distraction device was removed. The advanced maxilla was fixed with miniplates after adjusting the length and direction of advancement, and mandibular setback surgery was performed simultaneously to obtain a normal occlusal relationship. This 2-stage procedure resulted in stable occlusion and a markedly improved facial profile.

Abstract
Matrix metalloproteinases (MMPs) have been implicated in tissue degradation in varicose veins. The aim of this study was to investigate the effects of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) on the activity of MMPs in varicose veins. MMP-9 was present at significantly higher levels in varicose veins than in controls and was localized mainly in smooth muscle cells at the tunica media, where marked degradation of the extracellular matrix was observed. Both simvastatin and pravastatin strikingly suppressed MMP-9 activity in ex vivo culture of varicose veins. Simvastatin suppressed MMP-9 at both the mRNA and protein levels as well as at the urokinase-type plasminogen activator protein level, resulting in the dramatic suppression of MMP-9 activity induced by tumor necrosis factor-alpha. Therefore, statins suppress MMP-9 activity by multiple mechanisms in varicose veins, suggesting they may have clinical potential for the treatment of this disease.

Abstract
OBJECTIVE The aim of this study was to examine changes in awareness of oral health among Japanese university students. METHODS Between 1990 and 2004, a total of 51,650 students newly enrolled at the University of Tokyo responded to an annual written questionnaire on oral health. RESULTS (i) Approximately 60% of the students brushed their teeth twice a day. Female students brushed more frequently than male students. (ii) The percentage of students who brushed for 2-3 min per time decreased, while the percentage who brushed four or more minutes increased. (iii) The number of students who had learned how to brush properly increased. This trend was particularly clear-cut among male students, although the proportion of female students who had learned to brush properly remained higher than that of male students. (iv) The percentage of female students who sought treatment for malocclusion was higher than that of male students. The percentage of students who underwent orthodontic treatment increased from 11.6 to 19.7%. The percentage of female students who received orthodontic treatment was approximately twofold that of male students. (v) The percentage of students who had temporomandibular disorders was 0.7% in males and 1.5% in females. (vi) More than 40% of the students had periodontal diseases, with a higher prevalence among male students than female students. (vii) Approximately 20% of the students wanted to consult our service centre. CONCLUSIONS The awareness of oral health among new undergraduates at the University of Tokyo has improved over the past 15 years.

Abstract
A 59-year-old man visited our hospital complaining of epigastralgia. A large hard mass was palpable in the abdominal cavity. Abdominal computed tomography revealed large retroperitoneal cystic tumors. His left testis was hard and swollen. Under the diagnosis of testicular tumor and retroperitoneal lymph node metastasis, left radical orchiectomy was performed and the histopathological examination showed mature teratoma. He was diagnosed with nonseminomatous germ cell tumor and retroperitoneal lymph node metastasis (TNM classification stage IIC). He received three cycles of chemotherapy with bleomycin, etoposide, and cisplatin and we performed retroperitoneal residual tumor resection. Because the tumor tightly adhered to the aortic wall, abdominal aorta was resected and replaced by an artificial vessel. The post-operative course was uneventful. Histopathological diagnosis was cystopapillary adenocarcinoma and mature teratoma. The patient is well 1 and a half years after the operation without recurrence.

Abstract
PURPOSE To evaluate the efficacy of combined lumbar spinal and epidural (CLSE) anesthesia in retropubic radical prostatectomy. MATERIALS AND METHODS Twenty consecutive patients who underwent radical retropubic prostatectomy by a single surgeon (H.K.) under CLSE anesthesia from July of 2003 to February of 2004 were selected as subjects. They were compared with 20 consecutive patients who underwent radical retropubic prostatectomy performed by the same surgeon under combined general and epidural (CGE) anesthesia from April to December of 2002. Both periods were carefully selected to exclude radical prostatectomies with intraoperative complications to evaluate genuine effects of anesthesia. For lumbar spinal anesthesia, 0.5% hyperbaric bupivacaine hydrochloride or 0.5% hyperbaric tetracaine hydrochloride (dissolved in a 10% glucose solution) was used. An epidural tube was inserted for both lumbar spinal anesthesia and general anesthesia mainly for the purpose of controlling a pain after operation. RESULTS Intraoperative blood loss was significantly less in the CLSE anesthesia group compared with CGE anesthesia group (p = 0.024). Postoperative water drinking was started at 0.4 days (average) for CLSE anesthesia and at 1.1 days (average) for CGE anesthesia (p < 0.0001). Postoperative diet was begun at 0.7 days (average) for CLSE anesthesia and at 1.5 days (average) for CGE anesthesia (p < 0.0001). Compared with the CLSE anesthesia group, the mean of the highest intraoperative mean blood pressure was significantly higher in the CGE anesthesia group (p = 0.002). CONCLUSION Intraoperative blood loss was less, intraoperative change in blood pressure was less and recovery of postoperative intestinal peristalsis was earlier in patients who underwent prostatectomy under CLSE anesthesia than in patients who underwent prostatectomy under CGE anesthesia. We believe that prostatectomy under CLSE anesthesia is more advantageous than prostatectomy under CGE anesthesia.

Abstract
We retrospectively evaluated the effect of the surgical resection of the remaining tumor after modified M-VAC (methotrexate, vinblastine, doxorubicin and cisplatin) (m-M-VAC) treatment for locally advanced or metastatic urothelial carcinoma. In m-M-VAC therapy, methotrexate and vinblastine on 15 and 22 days were omitted from the classical M-VAC to avoid the discontinuation and the dose reduction, and duration of 1 course was shortened to 21 days from 28 days of the classical M-VAC. Seven patients with locally invasive or metastatic carcinoma of the renal pelvis, ureter, and bladder, 6 males and 1 female, with a median age 64.1 years, ranging from 49 to 77 years received m-M-VAC chemotherapy without severe side effects. In all patients, the residual viable carcinoma was completely resected and they achieved complete remission. The median survival time was 20 months (range, 7 to 61). Five of these 7 patients were still alive. Two patients had no recurrence and achieved long-term survival (survival duration; 61 and 39 months). Although further studies and long-term follow up are required, these results suggest that patients who present with locally advanced or metastatic urothelial carcinoma may benefit from surgical resection after m-M-VAC.

Abstract
BACKGROUND Abnormal intracellular Ca2+ homeostasis is an important modulator of chronic atrial fibrillation. Sarcolipin, a homologue of phospholamban, is specifically expressed in the atria, and may play an important role in modulating intracellular Ca2+ homeostasis in the atria. The aim of this study was to investigate the expression of sarcolipin mRNA in the atrial myocardium of patients with chronic atrial fibrillation. METHODS We analyzed the expression of sarcolipin, phospholamban, cardiac calsequestrin and sodium calcium exchanger mRNAs in the right atrial myocardium from nine patients with mitral valvular disease with atrial fibrillation (MVD/AF), nine patients with MVD who had normal sinus rhythm (MVD/NSR), and 10 control patients with normal sinus rhythm who received open heart surgery (controls). The expression of mRNA was measured using the ABI PRISM 7700 Sequence Detection System (Applied Biosystems, Foster City, CA). RESULTS Relative expression levels of sarcolipin mRNA were significantly lower in MVD/AF (0.60 +/- 0.11) than in either MVD/NSR (1.28 +/- 0.17, P < 0.01) or controls (1.10 +/- 0.10, P < 0.05). The expression levels of sarcolipin mRNA were significantly lower in the group with high values for right atrial pressure. The expression levels of phospholamban, cardiac calsequestrin and sodium calcium exchanger mRNAs were comparable among all three groups. CONCLUSIONS Chronic electrical and mechanical overload decreased the expression of sarcolipin mRNA in the right atrial myocardium in patients with chronic atrial fibrillation. Down-regulation of sarcolipin mRNA may be part of atrial fibrillation-induced atrial remodelling.

Abstract
Although M-VAC therapy is a standard chemotherapy for advanced transitional cell carcinoma, the treatment schedule has to be delayed or cancelled in many patients because of the toxicity. To reduce the toxicity we modified the treatment schedule of M-VAC treatment. The dosages of this simplified M-VAC therapy were 30 mg/m2 methotrexate (on day 1), 3 mg/m2 vinblastine (on day 2), 30 mg/m2 doxorubicin (on day 2) and 70 mg/m2 cisplatin (on day 2), with courses repeated every 21 days for four cycles as a principle. Seventeen patients with histologically proven advanced transitional cell carcinoma were treated with this simplified M-VAC therapy without dose modification or delay. The median number of cycles was 4. Neutropenia, anemia and thrombopenia (grade 4) was observed in 2, 1 and 2 patients respectively, but no drug-related deaths were observed. Complete response and partial response were achieved in 2 (12%) and 10 (59%) patients respectively. Of 2 complete responders one patient was alive without evidence of disease at 12 months and another patient died of the disease at 42 months. Of 10 partial responders 6 patients underwent the additional surgical resection of residual tumors. Of these 6 patients 3 patients are alive without evidence of disease at 6, 30 and 31 months. The remaining 3 developed recurrence and 2 died of the disease at 13 and 29 months. Five non-responders died of the disease at 5 months after the start of the therapy. Response rate of simplified M-VAC therapy was excellent and treatment duration was short. However, relapses were commonly observed as well as the original M-VAC treatment.

Abstract
Internal herniation through a defect of the uterine broad ligament is rarely encountered. We report a case of a 52-year-old woman in whom a closed bowel loop with approximation of its ends to the uterus was the definitive computed tomographic finding. This type of internal herniation should be considered in the differential diagnosis of female patients presenting with ileus.

Abstract
Postoperative superior mesenteric artery syndrome is a rare complication of left nephrectomy. We treated a case of superior mesenteric artery syndrome that occurred 7 days after radical left nephrectomy for renal cell carcinoma. The patient was a 54-year-old Japanese man who presented with gross hematuria. Abdominal computed tomography showed a 3.8 x 3.8 x 5 cm heterogeneous cystic mass in the left kidney. Transperitoneal left radical nephrectomy was performed because renal cell carcinoma was suspected. The patient resumed oral intake 3 days after surgery, but he began vomiting repeatedly from the 7th day after surgery. Gastroduodenography showed an abrupt vertical linear obstruction of the third portion of the duodenum. Superior mesenteric artery syndrome was diagnosed. Conservative therapy (indwelling nasogastric tube, intravenous hyperalimentation and postural changes) was effective.

Abstract
This study was undertaken to determine the C terminus of amyloid beta protein (Abeta), accumulated in vacuolated muscle fibers, and compare these findings to the level of oxidative stress. Eight patients with myopathies characterized by rimmed vacuoles (RVs) were analyzed. Monoclonal antibodies specific to Abeta40 or Abeta42(43) revealed that the Abeta42(43) immunoreactivity was solely distributed in the vacuolated muscle fibers, and that only a part was also immunopositive for anti-Abeta40. Quantitative analyses in four specimens, in which eight or more vacuolated muscle fibers were observed, revealed that the mean incidence of Abeta42(43)-positive muscle fibers was 79.5+/-6.2% in total vacuolated muscle fibers, whereas that of the Abeta40-positive fibers was 42.9+/-12.6%. The predominance of Abeta42(43) deposition was statistically significant ( P<0.05). Abeta deposition was then compared with the distribution of oxidative nucleic acid damage in muscle fibers using a monoclonal antibody against 8-hydroxy-2'-deoxyguanosine and 8-hydroxyguanosine (8OHdG&G). The cytoplasmic staining for anti-8OHdG&G was found not only in vacuolated muscle fibers, but also in other muscle fibers including morphologically normal ones. Positive staining was completely abolished by RNase pretreatment and, thus, was suggested to reflect an increase of cellular RNA oxidation. The distribution of 8OHdG&G was much broader than the Abeta deposition. These data suggest that Abeta42(43) is predominantly involved in the pathogenesis of muscle fiber degeneration with RVs, and that oxidative damage may precede Abeta deposition in muscle fibers and play a key role in the pathomechanism of myopathies with RVs.
