[Comparative studies on activities of antimicrobial agents against causative organisms isolated from patients with urinary tract infections (1997). II. Background of patients].

Clinical background was investigated on patients with urinary tract infections (UTIs) from whom 603 bacterial strains were isolated in 9 hospitals during the period from June, 1997 through May, 1998. 1. Distribution of age and sex of patients and type of infections Among males, those with ages less than 50 years were only 12.5%, and those in the 70's were most frequent (33.3%). Among females, those with ages less than 20 years were only 3.4%, and those in the 60's were the most frequent (22.9%). With regard to type of infections, more than a half of infections among males with ages 50 years or older were of complicated types, but most of infections among females were of uncomplicated types, especially those of ages less than 50 years. 2. Ages of patients and types of pathogens Escherichia coli was the most frequently isolated in uncomplicated and complicated UTIs without indwelling catheters. In complicated UTIs with indwelling catheters, Pseudomonas aeruginosa and Enterococcus faecalis had mainly detected, they had no relationship with ages. 3. Effect of antibiotic use on isolation frequencies of pathogens Use of antibiotics decreased pathogens isolated from patients with uncomplicated UTIs drastically (183 isolates before antibiotics compared to 13 after). Even isolated pathogens from patients with complicated UTIs decreased drastically with the use of antibiotics when indwelling catheters were not in use (175 isolates before antibiotics compared to 53 after), but when indwelling catheters were in use, antibiotics slightly decreased (109 isolates before antibiotics compared to 70 after). 4. Surgical procedures and types of causative organisms for UTIs E. faecalis were more isolated when a surgical procedures were used, and E. coli were more isolated when, they were not used in uncomplicated and complicated UTIs without indwelling catheters. In complicated UTIs with indwelling catheters, E. coli and E. faecalis were more isolated when a surgical procedures were used, and P. aeruginosa and Staphylococcus aureus were more isolated when they were not used.

[Comparative studies on activities of antimicrobial agents against causative organisms isolated from patients with urinary tract infections (1997). III Secular changes in susceptibility].

Susceptibilities to various antimicrobial agents were examined for Enterococcus faecalis, Staphylococcus aureus, Echerichia coli, Klebsiella spp., and Pseudomonas aeruginosa that were isolated from patients with urinary tract infections (UTIs) in 9 hospitals during June 1997 to May 1998, and the results were compared with those obtained during the same period in earlier years. 1. E. faecalis The MIC90s of quinolones for E. faecalis isolated from uncomplicated UTIs have changed better state during the latest period. Among E. faecalis strains, those with high susceptibilities to ampicillin (ABPC) and minocycline (MINO) appeared to had decreased during period of 1995-1997, which recovered during the latest period. 2. S. aureus The sensitive strains of S. aureus to imipenem (IPM) and clindamycin (CLDM) had increased during the period of 1996-1997, but those have decreased again during the latest period. 3. E. coli The susceptibilities of E. coli to MINO have been better in the latest period with the MIC90 was ranged from 2 to 4 micrograms/ml. The susceptibilities to quinolones of E. coli isolated from complicated UTIs had decreased during the period of 1995-1997, but those have recovered during the latest period. 4. Klebsiella spp. Among Klebsiella spp. strains isolated from uncomplicated UTIs, those with low susceptibilities to almost cephems have increased in the latest period. To other antimicrobial agents, the susceptibilities of Klebsiella spp. did not show any changes during the latest period. 5. P. aeruginosa The susceptibilities to most agents of P. aeruginosa did not show any changes, the decreased susceptibilities to cefozopran (CZOP), carbapenems and monobactams of P. aeruginosa observed in 1996 appeared to have been retrieved in 1997. These susceptibility changes should be utilized in determining clinical treatments.

Laparoscopic mesh repair of a reducible obturator hernia using an extraperitoneal approach.

We present a case of an 84-year-old woman with nonstrangulated, reducible obturator hernia treated with laparoscopic total extraperitoneal prosthetic hernia repair. Preoperative diagnosis was made based on the clinical findings. The patient's postoperative recovery has been uneventful, without complications. When a nonstrangulated obturator hernia is diagnosed preoperatively, this procedure is likely to be successful.

[Comparative studies on activities of antimicrobial agents against causative organisms isolated from patients with urinary tract infections (1996). II. Background of patients].

Clinical background was investigated on patients with urinary tract infections (UTIs) from whom 752 bacterial strains were isolated in 10 hospitals during the period from June, 1996 through May, 1997. 1. Distribution of age and sex of patients and type of infections. Among males, those with ages 40 years or older were more frequent, the higher the ages of them. Among females, those with ages in the 60's were the most frequent (24.6%), and those with ages in the 20's, 40's and 50's were about 13%. With regard to type of infections, more than a half of infections among males with ages 30 years or older were of complicated types, but most of infections among females were of uncomplicated types, especially among females of ages less than 60 years. 2. Ages of patients and types of pathogens. The higher the ages of patients, the lesser became the isolation frequencies of Escherichia coli, but the higher were those of Pseudomonas aeruginosa and Klebsiella spp. 3. Effect of antibiotic use on isolation frequencies of pathogens. Use of antibiotics decreased pathogens isolated from patients with uncomplicated UTIs drastically (231 isolates before antibiotics compared to 60 after). Even isolated pathogens from patients with complicated UTIs decreased drastically with the use of antibiotics when indwelling catheters were not in use (193 isolates before antibiotics compared to 75 after), but when indwelling catheters were in use, antibiotics apparently failed to decrease the isolation frequency. 4. Surgical procedures and types of causative organisms for UTIs. From cases of uncomplicated UTIs, E. coli was the most frequently isolated, followed by Enterococcus Faecalis and Klebsiella spp. E. coli was the most frequently isolated organism from complicated UTIs without indwelling catheters. When a surgical procedures were not done, E. coli was isolated most frequently. From cases of complicated UTIs with indwelling catheters, P. aeruginosa, E. coli and E. faecalis were the organisms that were mainly isolated, with isolation frequencies of 23.2%, 15.2, 12.2, respectively. When no surgical procedures were used, isolation frequencies of P. aeruginosa, E. faecalis and Enterobacter spp. were 17.2%, 13.8%, 13.8%, respectively.

Particularly, the MIC50s of imipenem and clindamycin were 0.125 microgram/ml or below in the latest period for the first time in our history. 3. E. coli The susceptibilities to piperacillin and quinolones of E. coli isolated from uncomplicated UTIs were better than those isolated from complicated UTIs. 4. Klebsiella spp. The susceptibilities to almost antimicrobial agents of Klebsiella spp. have been better during the latest period, compared to those during period of 1995-1996, but to ofloxacin and ciprofloxacin have appeared to have been lower. 5. P. aeruginosa The susceptibilities to quinolones of P. aeruginosa have been better during the latest period compared those during periods of 1995-1996. But, the susceptibilities to cefozopran, carbapenems and monobactams of P. aeruginosa isolated from complicated UTIs appeared to have been lower.

Preoperative diagnosis of strangulated obturator hernia using ultrasonography.

BACKGROUND: Obturator hernia is rarely recognized before surgical intervention, since it is relatively infrequent and its definitive diagnosis is difficult. To change this situation, we introduced ultrasound examination in 1993 for differential diagnosis of strangulated obturator hernia among patients with bowel obstruction of unknown cause. PATIENTS AND METHODS: Between 1993 and 1995, we encountered 15 patients with suspected obturator hernia based on the presence of bowel obstruction of unknown cause and so-called predisposing factors. These patients underwent ultrasound examinations. RESULTS: The 4 patients with bowel obstruction caused by strangulated obturator hernia were all correctly diagnosed preoperatively by ultrasonography and were successfully cured by surgery. The time required for diagnosis was shorter than reported previously (average 16.5 h). CONCLUSIONS: Ultrasonography is useful and reliable for the diagnosis of strangulated obturator hernia and can decrease the morbidity and mortality associated with delayed diagnosis.

Susceptibilities to various antimicrobial agents were examined for Enterococcus faecalis, Staphylococcus aureus, Escherichia coli, Klebsiella spp. and Pseudomonas aeruginosa that were isolated from patients with urinary tract infections (UTIs) in 11 hospitals during June, 1995 through May, 1996, and the results were compared with those obtained during the same period in earlier years. 1. Macrolide resistant E. faecalis isolated from uncomplicated UTIs during the latest study period appeared to have increased compared to those in previous study periods. More than 50% of the isolated E. faecalis during the latest study period were resistant to macrolide antibiotics, for the first time in our history. 2. No obvious changes were observed through the years for susceptibilities of S. aureus to various antimicrobial agents. Vancomycin (VCM) showed the highest activity against S. aureus, with MICs below 2 micrograms/ml or below. 3. Among E. coli strains, those with low susceptibilities to quinolones appeared to have increased over the years with MIC90 changed from between 0.125 microgram/ml or below and 0.5 microgram/ml in the 1989-1990 period to between 8 micrograms/ml and 128 micrograms/ml in the latest study period. 4. Klebsiella spp. showed higher resistance to most antimicrobial agents during periods of 1993-1994 and 1994-1995, but somewhat lower resistance during period of 1995-1996. No resistant Klebsiella spp. were detected from uncomplicated UTIs during the latest study period. 5. Among P. aeruginosa isolates from complicated UTIs, resistance isolates to gentamicin appeared to be increasing over the years. Resistant strains to quinolones were isolated at lower frequencies during periods of 1991-1994, but higher frequency was observed in the latest period, and MIC50s were between 0.5 and 4 micrograms/ml during 1991-1994, but were 16-32 micrograms/ml during 1995-1996. These susceptibility changes should be utilized in determining clinical treatments.

[Comparative studies on activities of antimicrobial agents against causative organisms isolated from patients with urinary tract infections (1995). I. Susceptibility distribution].

The frequencies of isolation and susceptibilities to antimicrobial agents were investigated on 704 bacterial strains isolated from patients with urinary tract infections (UTIs) in 11 hospitals during the period of June 1995 to May 1996. Of the above bacterial isolates, Gram-positive bacteria accounted for 29.8% and a majority of them were Enterococcus faecalis. Gram-negative bacteria accounted for 70.2% and most of them were Escherichia coli. Susceptibilities of several isolated bacteria to antimicrobial agents were as followed; 1. Enterococcus faecalis Ampicillin (ABPC) and imipenem (IPM) showed the highest activities against E. faecalis isolated from patients with UTIs. The MIC90S of them were 1 microgram/ml. Vancomycin (VCM) and piperacillin (PIPC) were also active with the MIC90S of 2 micrograms/ml and 4 micrograms/ml, respectively. The others had low activities with the MIC90S of 16 micrograms/ml or above. 2. Staphylococcus aureus including MRSA VCM showed the highest activities against S. aureus isolated from patients with UTIs. Its MIC90 was 1 microgram/ml against both S. aureus and MRSA. Arbekacin (ABK) was also active with the MIC90 of 2 micrograms/ml. The other except minocycline (MINO) had very low activities with the MIC90S of 64 micrograms/ml or above. 3. Staphylococcus epidermidis ABK and MINO showed the strongest activities against S. epidermidis isolated from patients with UTIs. The MIC90S of them were 0.25 microgram/ml. VCM was also active with the MIC90 of 1 microgram/ml. The MIC90S of cephems ranged from 2 micrograms/ml to 16 micrograms/ml in 1994, but they ranged from 8 micrograms/ml to 128 micrograms/ml in 1995. These results indicated that some resistances existed among S. epidermidis to cephems. 4. Streptococcus agalactiae All drugs except gentamicin (GM) were active against S. agalactiae. ABPC, cefmenoxime (CMX), IPM, erythromycin (EM), clindamycin (CLDM) and clarithromycin (CAM) showed the highest activities. The MICs for all strains were lower than 0.125 microgram/ml. The MIC90S of the others were 2 micrograms/ml or below. 5. Citrobacter freundii IPM showed the highest activity against C. freundii isolated from patients UTIs. Its MIC90 was 1 microgram/ml. GM was also active with the MIC90 of 2 micrograms/ml. Cefpirome (CPR), cefozopran (CZOP) and amikacin (AMK) were also active with the MIC90S of 4 micrograms/ml. Penicillins and cephems except CMX, CPR and CZOP showed low activities with MIC90S of 256 micrograms/ml or above. 6. Enterobacter cloacae IPM showed the highest activity against E. cloacae. The MICs for all strains were equal to or lower than 1 microgram/ml. MINO and tosufloxacin (TFLX) were also active with the MIC90S of 8 micrograms/ml. Penicillins and cephems except CPR and CZOP showed lower activities with the MIC90S of 256 micrograms/ml or above. 7. Escherichia coli. Most of the antimicrobial agents were active against E. coli. Particularly CPR, CZOP and IPM showed the highest activities against E. coli. The MICs for all strains were equal to or lower than 0.5 microgram/ml. CMX and TFLX were also active with the MIC90S of 0.125 microgram/ml or below. Penicillins were slightly active with MIC90S of 128 micrograms/ml or above. 8. Klebsiella pneumoniae K. pneumoniae was susceptible to all drugs except penicillins, with MIC90S of 2 micrograms/ml or below. Carumonam (CRMN) had the strongest activity against K. pneumoniae, the MICs for all strains were equal to or lower than 0.125 microgram/ml. Comparing with the result of 1994, the sensitivities of K. pneumoniae against all drugs had obviously changed into a better state. For example, the MIC90S of cephems ranged from 0.25 microgram/ml to 16 micrograms/ml in 1994, but they were all lower than 2 micrograms/ml in 1995. 9. Proteus mirabilis P. mirabilis was susceptible to a majority of drugs. CMX, ceftazidime (CAZ), cefixime (CFIX), and CRMN showed the highest activities against P. mirabilis isolated from patients with UTIs. MICs of CRMN for all

Clinical background was investigated on patients with urinary tract infections (UTIs) from whom 785 bacterial strains were isolated in 11 hospitals during the period from June, 1995 through May, 1996. 1. Distributions of age and sex of patients and type of infections. Among the patients examined, those with ages 50 years or older were the most frequent (males: 80.5%, females: 69.7%), and, among females, those with ages in the 20's were 12.6%. With regard to types of infections, more than a half of infections among males were of complicated types, but most of infections among females were of uncomplicated types, especially among females of ages less than 60 years. 2. Ages of patients and types of pathogens. The higher the ages of patients, the lesser became the isolation frequencies of Proteus spp. and Serratia spp., but the higher were those of Klebsiella spp. and Pseudomonas spp. 3. Effect of antibiotic use on isolation frequencies of pathogens. Use of antibiotics decreased pathogens isolated from patients with uncomplicated UTIs drastically (237 isolates before antibiotics compared to 33 after). Even isolated pathogens from patients with complicated UTIs decreased drastically with the use of antibiotics when indwelling catheters were not in use (200 isolates before antibiotics compared to 83 after), but when indwelling catheters were in use, antibiotics apparently failed to decrease the isolation frequency. 4. Surgical procedures and types of causative organisms for UTIs. Escherichia coli was the most frequently isolated organism from uncomplicated cases of UTIs. From cases of complicated UTIs without indwelling catheters, Enterococcus faecalis was the most frequently isolated, followed by E. coli, P. aeruginosa and Klebsiella spp. When a surgical procedures were not done, E. coli was isolated most frequently. From cases of complicated UTIs with indwelling catheters, P. aeruginosa, E. faecalis and S. aureus were the organisms that were mainly isolated, with isolation frequencies of 23.9%, 17.3% and 12.7%, respectively. When no surgical procedures were used, isolation frequencies of P. aeruginosa, Klebsiella spp. and E. faecalis were 25.7%, 14.3% and 14.3%, respectively.

[Clinical result of left ventricular free wall rupture resulting from acute myocardial infarction].

We have treated 10 patients of left ventricular free wall rupture (LVFWR) resulting from acute myocardial infarction (AMI) in our intensive care unit (ICU) from Oct. 1984 to Dec. 1993. Nine of 10 patients underwent surgical repair, however, one patient was treated with pericardocentetesis in ICU and fibrin-glue was infused into the pericardial space (fibrin-glue therapy:FG therapy). The survival rate of surgical repair was only 33% (3/9), especially that was only 17% (1/6) when cardiopulmonary bypass (CPB) was required. One patient (49-year-old, male) suffered from cardiogenic shock following AMI in the posterior wall was performed coronary angioplasty (PTCA) in emergency and IABP support was required. Fourth day after PTCA, a sudden hemodynamical collapse had occurred on this patient due to cardiac tamponade. This patient was treated with pericardiocentetesis in ICU and FG therapy was performed, because all surgical teams were occupied in their operations. After FG therapy hemodynamical stability was obtained, the patient was survived and discharged at 2 months after LVFWR. In conclusion, the surgical result of LVFWR is still not good, especially when CPB was utilized. FG therapy was successful in one patient, suggesting FG therapy can be an alternative therapy for LVFWR when surgical team is not available.

[Radiation therapy of carcinoma of the esophagus in the aged--its results and problems].

Clinical records of 128 non-selected patients with esophageal cancer treated by radiation were reviewed to investigate reasons why treatment had to be discontinued, relationship between age and survival, and factors influencing prognosis. Radiation therapy was completed in 77 patients but was discontinued in 27 patients. Preoperative radiation was attempted in 24 patients. An overall median survival of 128 patients was 6.4 months, with 8.5 and 3.3 percent surviving 3 and 5 years. Median survivals of incomplete RT, completed Rt and RT + Surgery were 1.3, 7.7 and 11.3 months. By Kaplan-Meier analysis significant difference was observed in survival rate between incomplete RT and the other two groups, but not between RT and RT + surgery. T1 tumor cases with incomplete RT were characterized by a higher C-Score (higher incidence of comorbidity and complications), lower albumin concentration and poor performance status. Median survivals of 60 years, 70 and 80 were 12, 5.4 and 6.2 months, respectively. Performance status and C-score were significantly different between the 60 yr and 80 yr groups. Survival rates were also apparently affected by the size of the primary tumor and metastasis. Thus important factors influencing prognosis were performance status, albumin concentration, and comorbidity and complications, in addition to stage of tumor itself. Although performance status and albumin concentration were considered directly related to tumor stage, old age may have an adverse effect on these factors through increase of comorbidity and complication. The data may be useful for decision making for treatment of esophageal cancer of the aged.

Ovarian and hepatic metastases of gastric carcinoma associated with high serum levels of human chorionic gonadotropin (hCG), alpha-fetoprotein (AFP), and carcinoembryonic antigen (CEA): a case report.

A 45-year-old woman who underwent gastrectomy for gastric carcinoma which had metastasized to the liver and ovaries, showed high serum levels of hCG, AFP and CEA. To locate the source, an immunohistochemical technique was utilized. HCG-producing cells were detected in poorly differentiated adenocarcinoma of a primary tumor and an ovarian metastatic site, and AFP-producing cells in poorly differentiated adenocarcinoma forming a medullary pattern of primary site and metastatic foci. CEA-producing cells were found diffused in primary tumor and metastatic foci. From the viewpoint of oncodevelopmental gene expression (Cancer Res 36:3423, 1976), it is interesting that the serum levels of these three tumor markers (hCG, AFP, CEA) were elevated simultaneously.
