RESUMO
A 79-year-old man underwent a transrectal prostate needle biopsy with a prostate-specific antigen (PSA) level of 12.0 ng/ml. He was diagnosed with adenocarcinoma (Gleason score 4ï¼3, cT3aN0M0) and underwent radiation therapy. Eight months later, he was administered hormone therapy because of a rise in PSA level to 8.4 ng/ml. One year and 5 months later, he experienced back pain, and computed tomography revealed multiple lymphadenopathies and irregular prostate enlargement. The PSA level was 0.097 ng/ml. Re-biopsy of the prostate and biopsy of the lymph node were performed. Pathological examination revealed neuroendocrine differentiation of the prostate. The disease progressed rapidly, and the patient died 4 months after the biopsy. Neuroendocrine differentiation of prostate cancer is rare, and its development may not be consistent with PSA levels. Therefore, periodic imaging examinations should be conducted, even when PSA levels are low.

The antibacterial activity of meropenem (MEPM) and other parenteral antibiotics against clinical isolates of 876 strains of Gram-positive bacteria, 1764 strains of Gram-negative bacteria, and 198 strains of anaerobic bacteria obtained from 30 medical institutions during 2006 was measured. The results were as follows; 1. MEPM was more active than the other carbapenem antibiotics tested against Gram-negative bacteria, especially against enterobacteriaceae and Haemophilus influenzae. MEPM was also active against most of the species tested in Gram-positive and anaerobic bacteria, except for multi-drug resistant strains including methicillin-resistant Staphylococcus aureus. 2. As for Pseudomonas aeruginosa, all of the MEPM-resistant strains were resistant to imipenem (IPM). MEPM showed low cross-resistant rate both againt IPM-resistant P. aeruginosa (41.8%) and ciprofloxacin-resistant P. aeruginosa (33.3%). 3. The proportion of extended-spectrum beta-lactamase (ESBL) strains was 4.3% (6 strains) in Escherichia coli, 1.1% (1 strain) in Citrobacter freundii, 21.7% (5 strains) in Citrobacter koseri, 3.1% (4 strains) in Klebsiella pneumoniae, 3.3% (3 strains) in Enterobacter cloacae, 0.8% (1 strain) in Serratia marcescens, and 4.9% (2 strains) in Providencia spp. The proportion of metallo-beta-lactamase strains was 3.1% (10 strains) in P. aeruginosa. 4. Of all species tested, there were no species, which MIC90 of MEPM was more than 4-fold higher than those in our previous study. Therefore, there is almost no significant decrease in susceptibility of clinical isolates to meropenem. In conclusion, the results from this surveillance study suggest that MEPM retains its potent and broad antibacterial activity and therefore is a clinically useful carbapenem at present, 11 years after available for commercial use.

The antibacterial activity of meropenem (MEPM) and other parenteral antibiotics against clinical isolates of 907 strains of Gram-positive bacteria, 1790 strains of Gram-negative bacteria, and 192 strains of anaerobic bacteria obtained from 30 medical institutions during 2004 was measured. The results were as follows; 1. MIC90 of MEPM for almost all of enterobacteriaceae and Haemophilus influenzae were 4-fold to 32-fold lower than those of other carbapenems. MEPM was more active than other carbapenem antibiotics against Gram-negative bacteria, especially against enterobacteriaceae and H. influenzae. MEPM were active against most of the species tested in Gram-positive and anaerobic bacteria, except for multi-drug resistant strains including methicillin-resistant Staphylococcus aureus. 2. As for Pseudomonas aeruginosa, imipenem (IPM) showed high cross-resistant rate againt meropenem-resistant P. aeruginosa (87.9%). MEPM showed low cross-resistant rate both againt IPM-resistant P. aeruginosa (49.2%) and ciprofloxacin-resistant P. aeruginosa (38.0%). 3. The proportion of extended-spectrum beta-lactamase (ESBL) strains was 3.1% (4 strains) in Escherichia coli, 8.0% (2 strains) in Citrobacter koseri, 2.5% (3 strains) in Klebsiella pneumoniae, 2.5% (2 strains) in Enterobacter cloacae, 0.9% (1 strains) in Serratia marcescens, and 2.2% (2 strains) in Proteus mirabilis. The proportion of metallo-beta-lactamase strains was 1.6% (5 strains) in P. aeruginosa. 4. Of all species tested, Peptostreptococcus spp. was the only species, which MIC90 of MEPM was more than 4-fold higher than that in our previous study using clinical isolates during 2002 (0.25 microg/ml --> 1 microg/ml). Therefore, there is almost no siginificant decrease in susceptibility of clinical isolates to meropenem. In conclusion, the results from this surveillance study suggest that MEPM retains its potent and broad antibacterial activity and therefore is a clinically useful carbapenem at present, 9 years after available for commercial use.

The antibacterial activity of meropenem (MEPM) and other parenteral antibiotics against clinical isolates of 899 strains of Gram-positive bacteria, 1500 strains of Gram-negative bacteria, and 158 strains of anaerobic bacteria obtained from 28 medical institutions during 2002 was measured. The results were as follows; 1. MEPM was more active than other carbapenem antibiotics against Gram-negative bacteria, especially against enterobacteriaceae and Haemophilus influenzae. MIC90 of MEPM against Pseudomonas aeruginosa was the lowest of the drugs tested. MEPM showed low cross-resistant rate against both imipenem-resistant P. aeruginosa and ciprofloxacin-resistant P. aeruginosa. MEPM was active against most of the species tested in Gram-positive and anaerobic bacteria, except for multi-drug resistant strains including methicillin-resistant Staphylococcus aureus (MRSA), methicillin-resistant Staphylococcus epidermidis (MRSE). 2. The proportion of extended-spectrum beta-lactamase (ESBL) strains was 3.1% (4 strains) in Escherichia coli and 1.9% (2 strains) in Klebsiella pneumoniae. Carbapenems including MEPM were active against these ESBL strains. In conclusion, the results from this surveillance study suggest that MEPM retains its potent and broad antibacterial activity and therefore is a clinically useful carbapenem; at present, 7 years after available for commercial use.

Self-mutilation of the penis is extremely rare. A 69-year-old man was admitted after having amputated his own penis completely from its root. He had no history of psychiatric illness, but his physical condition on admission was abnormal. We performed urethrocutaneostomy, rather than replantation of the penis, because of the danger that he would reinjure himself. The patient was treated by a psychiatrist under a diagnosis of alcoholic dementia. To our knowledge, this is the 24th case of self-mutilation of the penis reported in the Japanese literature.

PURPOSE: This study was undertaken to clarify the usefulness and problems involved in the clinical path of transurethral prostatectomy (TUR-P) in hospital. PATIENTS AND METHODS: The subjects consisted of 50 patients, for whom the Department of Urology, Jikei Medical University Hospital introduced its own clinical path and performed TUR-P during a period of 9 months from July 1999 to March 2000. The mean length of hospital stay, rate of postoperative complications, and the medical insurance claims made by these patients were clarified and compared with those of 73 patients before introduction of the clinical path. RESULTS: With the introduction of the clinical path, the length of hospital stay decreased by an average of 3.4 days and the total medical insurance claims decreased by an average of 18.5%. The rate of postoperative complications before and after introduction was almost equal. CONCLUSION: Our clinical path for TUR-P was well accepted by both patients and comedicals. However, the present medical treatment system in Japan is not as yet prepared to promote the introduction of this clinical path, and it will take some time before this clinical path is introduced on a full scale.

PURPOSE: We report on 48 clinicopathologic cases of inverted papilloma and present the clinical significance attributed to these lesions in terms of the current literature. MATERIALS AND METHODS: From 1976 to 2002 we had experience with 48 cases of inverted papilloma in urinary tract. We present the clinical features of these cases and report the results of prognosis research. RESULTS: Patient age ranged from 24 to 82 years (mean 56). Coexistence of transitional cell carcinoma occurred in a different location in the bladder in 3 cases and within a single neoplasm in the ureter in 2. Followup data were available in 42 of the 48 cases. Followup ranged from 8 months to 23 years 6 months (mean 8 years 1 month). Of the 42 cases 3 (7%) had a recurrence and range from initial resection at 5 months, 1 year 4 months and 2 years 6 months, respectively. CONCLUSIONS: 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.
