The third nationwide surveillance of antimicrobial susceptibility against Neisseria gonorrhoeae from male urethritis in Japan, 2016-2017. J Infect Chemother 2023; 29:1011-1016. [PMID: 37553046 DOI: 10.1016/j.jiac.2023.08.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Revised: 07/21/2023] [Accepted: 08/03/2023] [Indexed: 08/10/2023]
Abstract
Neisseria gonorrhoeae is one of the important pathogens of sexually transmitted infections. N. gonorrhoeae is rapidly becoming antimicrobial resistant, and there are few drugs that are effective in the initial treatment of gonorrhea. To understand the trends of antimicrobial susceptibility of N. gonorrhoeae, the Surveillance Committee of the Japanese Society of Infectious Diseases, the Japanese Society for Chemotherapy, and the Japanese Society of Clinical Microbiology conducted the third nationwide antimicrobial susceptibility surveillance of N. gonorrhoeae isolated from male urethritis. The specimens were collected from male patients with urethritis at 30 facilities from May 2016 to July 2017. From the 159 specimens collected, 87 N. gonorrhoeae strains were isolated, and 85 were tested for susceptibility to 21 antimicrobial agents. All strains were non-susceptible to penicillin G. Seven strains (8.2%) were β-lactamase-producing strains. The rates of susceptibility to cefixime and cefpodoxime were 96.5% and 52.9%, respectively. Three strains were non-susceptible with a minimum inhibitory concentration (MIC) of 0.5 mg/L for cefixime. None of the strains were resistant to ceftriaxone or spectinomycin. The susceptibility rate for ciprofloxacin was 23.5% (20 strains), and no strains showed intermediate susceptibility. The susceptibility rate against azithromycin was 81.2%, with one strain isolated with a MIC of 8 mg/L against azithromycin. The results of this surveillance indicate that ceftriaxone and spectinomycin, which are currently recommended for gonococcal infections in Japan, appear to be effective. It will be necessary to further expand the scale of the next surveillance to understand the current status of drug-resistant N. gonorrhoeae in Japan.

Predictive factors for efficacy of testosterone replacement therapy for late-onset hypogonadism in Japanese men: a preliminary report. Asian J Androl 2023; 25:374661. [PMID: 37147941 PMCID: PMC10521961 DOI: 10.4103/aja2022123] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Accepted: 02/27/2023] [Indexed: 05/07/2023] Open
Abstract
Although testosterone replacement therapy (TRT) is the first-choice method used worldwide for late-onset hypogonadism (LOH), clinical benefits are not seen in all cases. This study was conducted to determine the predictors of TRT efficacy for LOH. Fifty-six patients who visited our Men's Health Clinic (Kawanishi City Medical Center, Kawanishi and Hyogo Medical University, Nishinomiya, Hyogo, Japan) between November 2003 and June 2021 with data available before and after TRT were enrolled. They were divided into responders (Group 1; n = 45, accounting for 80.4%) and nonresponders (Group 2; n = 11, accounting for 19.6%) based on the clinical response to TRT, including patient satisfaction. Factors noted before TRT included age, body mass index, aging males' symptoms score, sexual health inventory for men, luteinizing hormone, follicular-stimulating hormone, testosterone, free testosterone, prolactin (PRL), estradiol (E2), and testosterone/estradiol (T/E2) ratio in serum. For statistical analysis, a multivariable logistic regression model was used. Univariate analysis revealed PRL (odds ratio [OR]: 0.9624; 95% confidence interval [CI]: 0.9316-0.9943, P < 0.05), E2 (OR: 0.8692; 95% CI: 0.7745-0.9754, P < 0.05), and T/E2 ratio (OR: 1.1312; 95% CI: 1.0106-1.2661, P < 0.05) to be predictive factors. Multivariate analyses showed that T/E2 ratio was an independent predictive factor (OR: 1.1593; 95% CI: 1.0438-1.2875, P < 0.01). The present results suggest that a low value for T/E2 ratio may predict a reduced response to TRT. The T/E2 ratio threshold to predict nonresponders based on receiver-operating characteristics (ROC) curve analysis was shown to be 17.3. Although additional studies with larger number of patients are necessary, we propose the determination of serum E2 level and testosterone level prior to performing TRT.

Abstract
The Urogenital Sub-committee and the Surveillance Committee of the Japanese Society of Chemotherapy, The Japanese Association for Infectious Diseases, and the Japanese Society for Clinical Microbiology conducted the second nationwide surveillance of the antimicrobial susceptibility of Chlamydia trachomatis. In this second surveillance study, clinical urethral discharge specimens were collected from patients with urethritis in 26 hospitals and clinics from May 2016 to July 2017. Based on serial cultures, the minimum inhibitory concentration (MIC) could be determined for 41 isolates; the MICs (MIC90) of ciprofloxacin, levofloxacin, tosufloxacin, sitafloxacin, doxycycline, minocycline, erythromycin, clarithromycin, azithromycin and solithromycin were 2 μg/ml (2 μg/ml), 1 μg/ml (0.5 μg/ml), 0.25 μg/ml (0.25 μg/ml), 0.125 μg/ml (0.063 μg/ml), 0.125 μg/ml (0.125 μg/ml), 0.25 μg/ml (0.25 μg/ml), 0.031 μg/ml (0.031 μg/ml), 0.25 μg/ml (0.125 μg/ml), and 0.016 μg/ml (0.008 μg/ml), respectively. In summary, this surveillance project did not identify any strains resistant to fluoroquinolone, tetracycline, or macrolide agents in Japan. In addition, the MIC of solithromycin was favorable and lower than that of other antimicrobial agents. However, the MIC of azithromycin had a slightly higher value than that reported in the first surveillance report, though this might be within the acceptable margin of error. Therefore, the susceptibility of azithromycin, especially, should be monitored henceforth.

Nationwide surveillance of bacterial pathogens isolated from patients with acute uncomplicated cystitis in 2018: Conducted by the Japanese Research Group for Urinary Tract Infections (JRGU). J Infect Chemother 2021; 27:1169-1180.

Abstract
INTRODUCTION The aim of this study was to monitor the development of drug-resistant bacteria isolated from acute uncomplicated cystitis (AUC) and to evaluate methodology of the survey conducted by collecting only clinical data. METHODS We enrolled female patients at least 16 years of age diagnosed with AUC in 2018. Patient information including age, menopausal status, and results of bacteriological examination were collected and analyzed regardless of bacterial identification, antimicrobial susceptibility testing or extended-spectrum β-lactamase (ESBL) detection method. RESULTS A total of 847 eligible cases were collected. Escherichia coli (E. coli) was the most frequently isolated bacterial species at about 70%, with proportions of fluoroquinolone-resistant E. coli (QREC) and ESBL-producing E. coli isolates at 15.6% and 9.5% of all E. coli isolates, respectively. The proportion of Staphylococcus saprophyticus (S. saprophyticus) was significantly higher in premenopausal women. Regarding the drug susceptibility of E. coli, isolates from Eastern Japan had significantly higher susceptibility to cefazolin, cefotiam and cefpodoxime and lower susceptibility to levofloxacin in postmenopausal women. ESBL-producing E. coli isolates had a high susceptibility to tazobactam-piperacillin, cefmetazole, carbapenems, aminoglycosides, and fosfomycin. In S. saprophyticus, the susceptibility to β-lactams including carbapenems was 40-60%. CONCLUSIONS The proportions of QREC and ESBL-producing E. coli were increasing trends and lower susceptibility to LVFX in postmenopausal women was observed. Such surveillance, consisting of the collecting only clinical data, could be conducted easily and inexpensively. It is expected to be continuously performed as an alternative survey to conventional one collecting bacterial strains.

Abstract
OBJECTIVES To assess the effect of cernitin pollen extract on serum prostate-specific antigen level prostate biopsy candidates, and to develop an ideal protocol to avoid an unnecessary biopsy procedure. METHODS A total of 61 patients were administrated cernitin pollen extract tablets (two tablets t.i.d.) for 30 days, and then underwent a prostate biopsy with ≥12 systematic and targeted biopsy cores obtained. Serum prostate-specific antigen levels were examined before and after administration of the pollen extract, and the change in serum prostate-specific antigen and the rate of change were analyzed in relation to negative and positive biopsy results for cancer. RESULTS The mean change in serum prostate-specific antigen and rate of change after administration of cernitin pollen extract in all patients were -0.6 ± 1.4 ng/mL and -7.6 ± 16.1%, respectively, which were significantly different from the baseline values (P = 0.0003 and P = 0.0005, respectively). When prostate-specific antigen change values and rates were compared between patients negative and positive for cancer, a significant difference between those groups was observed (P = 0.04 and P = 0.03, respectively). CONCLUSIONS The present study is the first to show that an ideal protocol using cernitin pollen extract has the potential to avoid an unnecessary prostate biopsy procedure in patients with elevated prostate-specific antigen, possibly caused by inflammation. Additional studies with greater numbers of participants are required to confirm our findings and develop an ideal protocol.

Abstract
Although febrile complications are rarely encountered after a prostate biopsy procedure, in recent years the number of cases of fatal infection after that have increased along with increases in resistant bacteria. The available biopsy approaches are transrectal and transperineal, with the transrectal approach primarily used. As the invasion path of the puncture needle differs between these approaches, pretreatment and the method of administration of preventive antimicrobial drugs should be separately considered for infection prevention. Recently, the Japanese guidelines for perioperative infection prevention in the field of urology were revised after receiving approval from the Japanese Urological Association. With use of the transrectal approach, attempts have been made to selectively administer prophylactic antibiotics by confirming the presence or absence of resistant bacteria in rectal swab culture results before carrying out a prostate biopsy procedure because of potential problems associated with resistant bacteria in rectal flora. For preventive antibiotics, a single dose of oral quinolone is recommended for patients with low risk, whereas daily administrations of piperacillin/tazobactam are recommended for those considered to be high risk. In contrast, for the transperineal procedure, a single dose of oral quinolone is recommended as a preventive antibiotic. With both approaches, it is important to empirically administer broad-spectrum antimicrobials when occurrence of a febrile infection after a prostate biopsy procedure is confirmed.

Abstract
Somatic mutations of the BRCA1 associated protein-1 (BAP1) gene, which maps to 3p21, have been found in several tumors including malignant mesothelioma, uveal melanoma, and renal cell carcinoma (RCC). The role of BAP1 inactivation in tumor development remains unclear. It has been reported that Vhl knock-out mice did not develop RCC, but Vhl knock-out mice with single allele loss of Bap1 in nephron progenitor cells developed RCC, indicating that Bap1 inactivation may be essential in murine renal tumorigenesis. To clarify the role of BAP1 in human RCC development, we performed mutation analyses, including copy number detection of BAP1 and assessment of allelic imbalance using microsatellite polymorphisms on 3p, in 45 RCC samples derived from 45 patients without VHL or BAP1 germline mutation. Additionally, we analyzed the sequences of the VHL, PBRM1, and SETD2 genes, and examined promoter methylation of VHL. Using immunostaining, we also checked for expression of BAP1 protein, which is normally located in the nuclei. None of the RCCs had biallelic deletion of BAP1, but five (11.1%) showed a biallelic mutation (four with a sequence-level mutation with monoallelic loss and one with a biallelic sequence-level mutation); these cells were negative for nuclear BAP1 staining. These patients had worse recurrence-free survival than the patients without a biallelic mutation (p=0.046). However, there were no significant differences in worse outcome by multivariate analysis combined with age, T stage, histological subtype, infiltration and vascular invasion. In 35 RCCs (77.8%), monoallelic loss of BAP1 was accompanied by VHL biallelic mutation or VHL promoter hypermethylation. In five RCCs (11.1%), we detected 3p loss-of-heterozygosity, but the copy number of BAP1 was normal. Surprisingly, nuclear staining of BAP1 was negative in 10 out of 31 tumors (32.3%) with hemizygous normal BAP1, suggesting that haploinsufficiency may relate to RCC development.

Abstract
A man in his 50s was referred to our hospital after recurrent severe urinary tract infection. He had undergone anoplasty for anorectal malformation during early infancy. He noticed urinary leakage from the anus for a long time. Under diagnosis of congenital rectourethral fistula, we performed fistula closure. The fistula was transsected via transperineal incision and each stump was closed. A gracilis muscle flap approximately 30 cm long was harvested from the left thigh, brought into the deepest part between the separated rectum and urethra through a subcutaneous tunnel and fixed there. The urinary leakage from the anus disappeared, and the infection resolved. Application of gracilis muscle flap for congenital diseases is rare, but was useful in the present case.

Abstract
A 47-year-old woman came to our hospital with left lower abdominal pain in April 2013. An abdominal computed tomographic (CT) examination revealed left hydronephrosis secondary to a 7 cm retroperitoneal cyst near the left common iliac artery and ureter. Serum tumor markers including CEA, CA19-9, and CA125 were negative. Although CT guided needle aspiration of the cyst successfully relieved severe left flank pain, the cyst again increased in size, causing left hydronephrosis, though examinations for fluid tumor markers and cytology were negative. Two months later, the patient underwent open fenestration. The final pathological results demonstrated a mesothelial cyst without malignant findings. Six months after the operation, the patient was doing well without recurrence of symptoms.

Abstract
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) triggers apoptosis in a variety of tumor cells by engaging the death receptors 4 (DR4) and 5 (DR5). We investigated the effect of chemotherapeutic drugs on DR4-mediated apoptosis in human bladder cancer cells, using a human monoclonal agonistic antibody specific for DR4, mapatumumab. Cytotoxicity was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Synergy was assessed by isobolographic analysis. Treatment of human bladder cancer T24 cells with mapatumumab in combination with mitomycin C, vinblastine or gemcitabine did not overcome resistance to these agents. However, treatment with mapatumumab in combination with epirubicin (EPI) had a synergistic cytotoxic effect. Synergy was also obtained in KU7 and RT112 human bladder cancer cells. A synergistic effect was also observed with mapatumumab in combination with pirarubicin. The synergy obtained in cytotoxicity with mapatumumab and EPI was also achieved in apoptosis. EPI markedly increased DR4 expression in the bladder cancer cells at both the mRNA and protein levels. Furthermore, the combination-induced cytotoxicity was significantly suppressed by the DR4:Fc chimeric protein. The combination of EPI and mapatumumab significantly activated the caspase cascade, including caspase-8, -9 and -3, which are the downstream molecules of death receptors. These findings indicate that EPI sensitizes bladder cancer cells to DR4-mediated apoptosis through induction of DR4 and activation of caspases, suggesting that the combination therapy of EPI and mapatumumab may be effective for bladder cancer therapy.

Abstract
We prospectively investigated the safety and efficacy of sunitinib using a modified regimen (2 weeks on/1 week off) in 24 patients (22 males, 2 females ; age range 39-86 years, median 64 years) with metastatic renal cell carcinoma (RCC). During the observation period (3-62 weeks, median 21 weeks), thrombocytopenia was seen in 13 (54.2%), leukopenia in 11 (45.8%), hand-foot syndrome in 5 (20.8%), hypertension in 4 (16.7%), and hypothyroidism in 3 (12.5%) patients, while grade 3 or higher adverse events were found in 4 (16.7%), 1 (4.2%), 1 (4.2%), 2 (8.3%), and 0 patients, respectively. Of the 21 patients evaluable for response, 5 (23. 8%) showed partial response, 8 (38.1%) stable disease, and 8 (38.1%) progressive disease. This new modified regimen may lead to a reduction in adverse events for treatment of patients with metastatic RCC as a substitute for the standard dosing regimen of sunitinib.

Abstract
A 37-year-old woman with an incidentally found abdominal mass was referred to our hospital. A fixed, non-tender mass was palpated in the right upper quadrum of her abdomen. There was no elevation of tumor markers. Computed tomography revealed a mass extending from the hepatic vein level to renal hilar level. The tumor completely obstructed the inferior vena cava (IVC). T1-weighted magnetic resonance imaging (MRI) showed that the mass was isointense with muscles. T2-weighted MRI image with contrast medium demonstrated collateral circulation. Upon diagnosis of the IVC tumor, we removed the right kidney and the tumor en bloc without reconstructing IVC. The tumor diameter was 11.6 × 5.5 × 4.7 cm. Pathological examination established a diagnosis of IVC leiomyosarcoma. She is alive without sign of recurrence after operation for seven months. There were 143 reports of IVC leiomyosarcoma in Japan. In 31% of them, IVC was not reconstructed.

[Impacted ureteral stents with cystine encrustation in cystinuric patients : report of two cases]. HINYOKIKA KIYO. ACTA UROLOGICA JAPONICA 2013; 59:651-655.

Abstract
A 23-year-old man and a 62-year-old man suffering from cystinuria underwent extracorporeal shock wave lithotripsy (ESWL) for right renal stone and left ureteral stone, respectively. They had double-J stents placed before ESWL, but since attempts to retrieve the stents were unsuccessful due to encrustation, they were referred to our clinic. Multimodal endourologic and open approaches including ESWL, transurethral ureterolithotripsy, and pyelolithotomy were required to render them stent- and stone-free. The guidelines do not recommend routine stenting before ESWL ; therefore, the indication and duration of indwelling stents should be minimized. Multimodal options including not only ESWL and endoscopic surgery but also open surgery, should be attempted for the management of encrusted stents. Close monitoring and follow up are important to the prevent complications of ureteral stents.

Abstract
Patients administered anti-cholinergic agents, as first-line therapy for an overactive bladder (OAB) are often unable to continue medical treatment because of dry mouth. We assessed oral health in patients with OAB using the General Oral Health Assessment Index (GOHAI), an oral health-related quality of life questionnaire. We investigated 75 patients with OAB who were receiving continuous administration of anti-cholinergic agents. The OAB symptom score, as well as GOHAI and our original dry mouse score were determined by self-administered questionnaires. The mean age of the subjects was 70.9±10.2 years, the median period of anti-cholinergic agent use was 20 (1-116) months and the mean OAB symptom score was 6.3±3.1. The GOHAI score for all patients was 51.9±8.4 and not significantly different from the national normal value (p=0.22). On the other hand, the score in patients with a severely dry mouth was 49.2±8.6, which was worse than the national normal value (p=0.04). The psychosocial functioning score in patients with a severely dry mouth was significantly lower than in those with a slightly dry mouth (p=0.02). Our results indicate that dry mouth in patients with OAB is significantly associated with worsening of oral health. GOHAI is useful as a screening test to assess the quality of life in patients with OAB.

Abstract
A 73-year-old male, admitted to a local hospital because of fever and consciousness disturbance, was referred to our institute. He had a history of long-term steroid administration and diabetes mellitus. Under diagnosis of severe right pyonephrosis associated with severe inflammatory response syndrome as well as disseminated intravascular coagulopathy, he was transferred to our hospital. Computed tomography and magnetic resonance imaging showed a mass 5 cm in diameter at the right ureteropelvic junction and lymph node swelling at the renal hilum, suggesting obstructive pyonephrosis by a malignant tumor such as renal pelvic cancer. Since the patient failed to respond to conservative medical treatment including polymyxin B hemoperfusion, hemodialysis, and antimicrobials, we performed right nephrectomy. Histopathological examination demonstrated that the tumor obstructing the pelvis arose from the parenchyme under the muscle layer, and was diagnosed as unclassified renal cell carcinoma while the renal pelvic epithelium was normal. Although his general condition and laboratory data transiently improved after nephrectomy, he died of carcinomatous peritonitis 30 days postoperatively. We advocate that, in the case of pyonephrosis with a lesion highly suspected to be an infiltrating neoplasm, nephrectomy is justified as first choice to control the septic condition.

Abstract
OBJECTIVES This investigation aimed to conduct a case-control study of mandibular morphology and dental anomalies to propose a relationship between mandibular/dental phenotypes and deficiency of CCAAT/enhancer-binding protein beta (CEBPB). MATERIALS AND METHODS Skulls of CEBPB(-/-), CEBPB(+/-) and CEBPB(+/+) mice were inspected with micro-computed tomography. Mandibular morphology was assessed with a method of Euclidean distance matrix analysis. RESULTS Elongation of the coronoid process was identified in CEBPB(+/-) (P ≤ 0.046) and CEBPB(-/-) 12-month-olds (P ≤ 0.028) but not in 14-day-olds (P ≥ 0.217) and 0-day-olds (P ≥ 0.189) of either genotype. Formation of supernumerary teeth in CEBPB(-/-) adult mice was demonstrated (χ(2) = 6.00, df = 1, P = 0.014). CONCLUSIONS CEBPB deficiency was related to elongation of the coronoid process and formation of supernumerary teeth. The mandibular and dental phenotypes of CEBPB deficiency were unseen by the 14th day after birth. Future investigations into the influence of CEBPB on mandibular and dental development are needed.

Abstract
We have performed transurethral enucleation with bipolar system (TUEB) on 60 patients since April 2008. The patients were 61 to 81 years old (average 71.7 years old), and estimated prostate volumes were 25 cm3 to 80.43 cm3 (average 51.1 cm3). The weight of prostate removed was 8 g to 56 g (average 27.4 g) during the operations which lasted between 40 min to 200 min (average 117.5 min). The International Prostate Symptom Score (IPSS), quality of life index (QOL) maximum flow rate (Q max) and average flow rate (Qave) were recorded before operation, and at 1 and at 3 months after operation. The results indicated a high safety with TUEB compared to TUR-P even for beginners. In conclusion, TUEB may become the most common approach in the treatment of BPH.

Abstract
A 74-year-old man visited our hospital, because of high prostate specific antigen (PSA). Retropubic radical prostatectomy was performed for prostatic cancer. Suddenly right inguinal lesion pain appeared at 25 days after operation with disturbance of gait. Pelvic magnetic resonance imaging (MRI) demonstrated inflammatory change in right pubic bone, pectineal muscle, adductor muscle, which suggested the diagnosis of osteomyelitis of the pubis. After long-term administration of antibiotic therapy, osteomyelitis of the symphysis pubis and gait possible. There was no recurrence of osteomyelitis of the symphysis pubis at one year after operation. In addition to our case, we review the 8 cases of osteomyelitis of the pubis after radical prostatectomy previously reported in Japanese publications.

Abstract
We retrospectively analyzed the records of 21 patients with penile carcinoma treated between January 1993 and February 2007. According to TMN classification (UICC 2002), 9, 8, 2 and 2 patients belonged to stages I, II, III and IV, respectively. During the follow up period of 4 to 144 months (median 15 months), the overall 5-year survival rate was 75.8%. All three patients having N2 died within one year. Lymph node metastasis (p = 0.001) and organ metastasis (p = 0.007) were found to be unfavorable prognostic factors for patients with penile cancer.

Abstract
We report a case of prostate cancer in a 45-year-old. The patient was found to have an elevated prostate specific antigen (PSA) level at a general health check and was referred to our division. Serum level of PSA was 6.9 ng/ml. Digital rectal examination and magnetic resonance imaging revealed a small nodule on the right lobe. Transperineal needle biopsy of the prostate revealed adenocarcinoma at the bilateral lobe (Gleason score 3+4). Computed tomography and a bone scan showed no evidence of metastasis. The patient was diagnosed as cT2b, NO, MO, and underwent a radical prostatectomy. Patients younger than 45 with prostate cancer are rare, although the incidence of prostate cancer is increasing. Here, 25 cases previously reported in Japan in addition to the present case, are reviewed.

Abstract
A 54-year-old woman consulted our hospital with the complaint of microscopic hematuria and proteinuria. Abdominal computed tomographic scan revealed a tumor mass on the lower pole of the left kidney. Left radical nephrectomy was performed under the diagnosis of renal cell carcinoma. The pathological diagnosis was a collision tumor consisting of renal cell carcinoma (clear cell type, G3, INFalpha, pT1b, v -) and urothelial carcinoma of the renal pelvic (G3 >> G2, pT3, ly + , v +). Postoperative chemotherapy was not given. Convalescence was uneventful and one year after the operation she is alive with no recurrence or metastasis.

Abstract
A 45-year-old man felt sudden pain in the left abdomen while taking a bath. Computed tomography (CT) showed a huge hematoma above the left kidney, which was diagnosed as spontaneous rupture of the kidney. Two months later, several low-density areas were observed in the liver on CT. Suspecting renal cell carcinoma (RCC) with multiple liver metastasis, we performed left radical nephrectomy and partial hepatectomy. A pathological study revealed a small RCC of 2 cm in diameter in the middle of the left kidney. In spontaneous renal rupture secondary to renal tumors, imaging studies such as CT or MRI sometimes fail to demonstrate primary lesions.

Abstract
A 86-year-old woman presented with asymptomatic gross hematuria,and visited our hospital, and a vesicorectal fistula was suspected from a computed tomographic (CT) scan. She had a lower abdominal mass and urinary retention on arrival. Pclvic CT demonstrated intramural gas in the urinary bladder,which suggested a diagnosis of emphysematous cystitis. Cystoscopy demonstrated reddish mucosa and gas within the bladder wall. The gross hematuria was improved and the intramural gas disappeared on a CT scan after urinary drainage and antibiotic therapy. Although emphysematous cystitis is almost always cured with conservative therapy, an accurate diagonosis and prompt treatment are required because rarely emphysematous cystitis can result in rupture of the urinary bladder and lead to septic shock.

Abstract
A 75-year-old male visited our division with asymptomatic erythema on the glans penis which he first noticed six months earlier. The patient underwent total cystoprostatectomy under the diagnosis of urothelial carcinoma of the urinary bladder four years earlier. At the time, the prostatectomy specimen incidentally revealed a prostatic acinar adenocarcinoma at the bilateral peripheral zone. A skin biopsy of the erythema revealed intraepithelial Paget's cells, and the patient underwent total penectomy under the diagnosis of extramammary Paget's disease. Histopathological examination revealed continuous intraepithelial Paget's cells from the glans penis to the urethral navicular fossa, and a ductal carcinoma was detected beneath the urethral mucosa to the excisional margin. Because the Paget's cells expressed cytokeratin 20, the tumor was diagnosed as Pagetoid spread rather than Paget's disease. Re-examination of the previous prostatectomy specimen revealed prostatic duct adenocarcinoma with prostatic acinar adenocarcinoma. Therefore, the final diagnosis was prostatic duct adenocarcinoma with Pagetoid spread to the glans penis. Follow up at nine months revealed neither local recurrence, nor distant metastases, although no adjuvant therapy has been given.

Abstract
A 55-year-old woman presented with sudden right lower abdominal pain. Computed tomography demonstrated retroperitoneal hematoma associated with minus-density area, diagnosed as spontaneous rupture of angiomyolipoma. Super-selective transarterial embolization was performed, but anemia and right abdominal pain became worse in spite of conservative therapy including transfusion, indicating re-rupture of the renal tumor. Although partial nephrectomy was planned, right nephrectomy was finally performed because of massive intraoperative bleeding. Accurate diagnosis and prompt treatment are required when life-threatening rupture of renal tumor is suspected.

Abstract
To elucidate the first pass metabolism of the dopamine prodrug N-(N-acetyl-L-methionyl)-O,O-bis(ethoxycarbonyl)dopamine (TA-870) in the small intestine and liver of dogs, the blood and plasma concentrations of unchanged TA-870 and metabolites in the gastroduodenal vein, portal vein, hepatic vein, and abdominal aorta were measured by HPLC after intraduodenal administration of TA-870. In addition, an in vitro metabolic study of TA-870 was carried out using liver, small intestinal wall, and blood homogenates of dogs. The order of maximal concentration (Cmax 0-30 min) in gastroduodenal blood or plasma was unchanged TA-870 greater than deethoxycarbonylated TA-870 (DEC-TA-870) greater than conjugated dopamine greater than free dopamine (DA) greater than free homovanillic acid (HVA) greater than free 3,4-dihydroxyphenylacetic acid (DOPAC). This result showed that the main pathway of metabolism in the small intestine is catechol ester hydrolysis and minor pathways are amido hydrolysis, oxidative deamination, and catechol 3-O-methylation. The order of Cmax in the hepatic vein and abdominal aorta was conjugated DA greater than free DEC-TA-870 greater than free HVA greater than free DA greater than free DOPAC greater than conjugated DOPAC greater than unchanged TA-870. The main metabolic pathways in the liver were hydrolyses of ester and amido-linkage of TA-870 and conjugation of DA. In the in vitro studies, the main metabolites of TA-870 in liver, small intestinal wall, and blood homogenates were DEC-TA-870, 3- or 4-mono-deethoxycarbonylated TA-870, DA, and an unknown compound.(ABSTRACT TRUNCATED AT 250 WORDS)
