Neisseria gonorrhoeae strains with reduced susceptibility to cefixime (MICs, 0.25 to 0.5 g/ml) were isolated from male urethritis patients in Tokyo, Japan, in 2000 and 2001. The resistance to cephems including cefixime and penicillin was transferred to a susceptible recipient, N. gonorrhoeae ATCC 19424, by transformation of the penicillin-binding protein 2 gene (penA) that had been amplified by PCR from a strain with reduced susceptibility to cefixime (MIC, 0.5 g/ml). The sequences of penA in the strains with reduced susceptibilities to cefixime were different from those of other susceptible isolates and did not correspond to the reported N. gonorrhoeae penA gene sequences. Some regions in the transpeptidase-encoding domain in this penA gene were similar to those in the penA genes of Neisseria perflava (N. sicca), Neisseria cinerea, Neisseria flavescens, and Neisseria meningitidis. These results showed that a mosaic-like structure in the penA gene conferred reductions in the levels of susceptibility of N. gonorrhoeae to cephems and penicillin in a manner similar to that found for N. meningitidis and Streptococcus pneumoniae.
Objective To investigate the incidence of bone fractures in patients receiving luteinizing hormone-releasing hormone agonists (LHRH-a) for prostate cancer (in whom a continued low testosterone level after the long-term administration of these drugs reduces bone mineral density), and thus determine the risk of secondary osteoporosis. Between 1994 and 1999, 218 patients (mean age 77.3 years) were treated for o 6 months with LHRH-a for prostate cancer; of these, 14 (6%) had a bone fracture during their treatment. Patients with fracture associated with motor vehicle accidents were excluded. The bone density in the third lumbar vertebra was measured using quantitative computed tomography. Osteocalcin, 1,25-(OH) 2 vitamin D, urinary type 1 collagen cross-linked N-telopeptides (NTx), parathyroid hormone and calcitonin were measured as metabolic markers. Results The mean age of the patients with fracture was 78 years; the mean (range) interval from the start of treatment to fracture was 28 (11±46) months. There was no case of a bone fracture at the site of a metastasis from prostate cancer. The bone density was signi®cantly lower in the patients with a fracture than in those without. Of the bone metabolic markers, NTx was higher in those with a fracture. Conclusion There is a need to measure bone mineral density and bone metabolic markers periodically, and to evaluate secondary osteoporosis in patients receiving long-term LHRH-a for prostate cancer.
Patients and methods
Our study suggests that there are 2 types of urinary inverted papilloma. The lesions in 1 type behave in a benign fashion and in another they have malignant potential. At this time we have no strategy with which to distinguish the 2 types of urinary inverted papilloma. Our results indicate that we must follow all cases for at least more than 2 years after initial treatment.
Objective To evaluate the ef®cacy of transcatheter arterial embolization (TAE) in patients with unresectable renal cell carcinoma (RCC) and distant metastasis at the time of diagnosis. Patients and methods The study included 54 patients with histologically de®ned RCC (by biopsy in 28 and autopsy in 26) who were unable to undergo nephrectomy mainly because their performance status was poor (score o 2). The patients were classi®ed into two groups; 24 patients who underwent TAE with ethanol and 30 patients who did not. The two groups were compared for several clinical factors, mainly focusing on the prognosis. Results There were no signi®cant differences in the clinical factors, including performance status, tumour diameter, vascular invasion, lymph node involvement, adjuvant therapy, metastatic organs or the number of metastases between the groups. However, the proportion of patients with para-neoplastic signs in those undergoing TAE was greater than that in those not, and the difference was signi®cant (chi squared 0.35, P<0.05). The median survival of the two groups was 229 days (TAE) and 116 days (no TAE). The 1-, 2-and 3-year survival rates in the TAE group were 29%, 15% and 10%, respectively, and in those not undergoing TAE were 13%, 7% and 3%, respectively. Those undergoing TAE had a signi®-cantly better prognosis than those who did not (P=0.019). The adverse effects in patients undergoing TAE with ethanol included fever, back pain on the affected side, nausea and vomiting, but all the patients recovered from these adverse effects. Conclusion TAE with ethanol is a safe and effective treatment for patients with unresectable disseminated RCC and a poor performance status; TAE with ethanol not only induces ablation of the primary tumour, but also prolongs survival.
Xanthogranulomatous cystitis (XC) is a rare benign chronic inflammatory disease of unknown etiology. Herein we report a case of a 70-year-old woman who presented with frequent, postmicturition pain and lower abdominal discomfort. Cystoscopy revealed a mass at the dome of the bladder near the left wall. Enhanced computed tomography (CT) demonstrated a mass with a central cavity.The patient underwent partial cystectomy because the presence of bladder neoplasm could not be ruled out. She had has no recurrence of XC 29 months after the operation. The present case of XC is the 20th to be reported in the world.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
