The clinical effects and tolerability of micafungin sodium in daily practice for the treatment of fungal infection in critically ill patients were evaluated in an open-labeled, non-comparative, observational study. All patients admitted to intensive care units (ICUs) of 3 hospitals in Chiba prefecture between June 2003 and March 2005, who were treated with micafungin because of known or suspected fungal infection, were included in the study. A total of 34 patients received micafungin and 29 cases of them were subjected to analysis. Fungal infections were classified as "proven" in 3 patients (10.3%) and "possible" in 26 (89.7%). Candida was detected in 16 patients, most of them were Candida albicans and 4 cases were non-albicans Candida. Clinical effects of micafungin were "cured" and "improved" in 20 patients (77%), "failure" in 6 (23%), and "undetermined" in 3 cases. Adverse events were reported in 10 patients, but there was no significant event. In conclusion, micafungin was effective in 77% of proven or suspected fungal infections in critically ill patients admitted to the ICU. The drug was well tolerated and discontinuation of its treatment due to adverse events was not experienced during the study period. [ABSTRACT FROM AUTHOR]

- Abstract
In this study, we investigated the correlations of values of biochemical and hematological tests obtained using microliter-scale fingertip blood samples collected with a newly developed blood collection device with those using conventional venous blood. Eighty volunteer subjects were enrolled in the study. Blood sam- ples were drawn from the fingertip of the ring finger by a single puncture and 60 μL of each sample was promptly and accurately aspirated into a blood collection chip. Then the chip was tightly sealed with chip container and was shaken to mix the contents without dispersing. For biochemical tests except of HbAlc, blood was collected without anticoagulant and centrifuged to obtain 15 μL of serum which was then diluted with 190 pL of physiological saline for the assay. For hematological tests and HbAlc, the sample was as- sayed with blood collected using EDTA-2K. As a result, a good correlation of the test values was obtained between the assay with fingertip blood and that with venous blood. The correlation coefficients were found to be 0.97 in TG, T-CHO, HDL-C, LDL-C, GLU, ALT, γ-GTP, UA, BUN and HbAlc and ≥ 0.95 for WBC, RBC, Hgb, and Hct. These results suggest that our microliter-scale blood testing can be comparable to the assay using venous blood and may be useful as a rapid and simple test for determination of basic clinical tests near the reference intervals.

- Abstract
Bacteria isolated from surgical infections during the period from April 2011 to March 2012 were investigated in a multicenter study in Japan, and the following results were obtained. In this series, 785 strains including 31 strains of Candida spp. were isolated from 204 (78.8%) of 259 patients with surgical infections. Five hundred and twenty three strains were isolated from primary infections, and 231 strains were isolated from surgical site infection. From primary infections, anaerobic Gram-negative bacteria were predominant, followed by aerobic Gram-negative bacteria, while from surgical site infection aerobic Gram-positive bacteria were predominant, followed by anaerobic Gram-negative bacteria. Among aerobic Gram-positive bacteria, the isolation rate of Enterococcus spp. was highest, followed by Streptococcus spp. and Staphylococcus spp., in this order, from primary infections, while Enterococcus spp. was highest, followed by Staphylococcus spp. from surgical site infection. Among aerobic Gram-negative bacteria, Escherichia coli was the most predominantly isolated from primary infections, followed by Klebsiella pneumoniae, Pseudomonas aeruginosa and Enterobacter cloacae, in this order, and from surgical site infection, E. coli was most predominantly isolated, followed by P. aeruginosa, K. pneumoniae, and E. cloacae. Among anaerobic Gram-positive bacteria, the isolation rate of Eggerthella lenta was the highest from primary infections, followed by Parvimonas micra, Collinsella aerofaciens, Lactobacillus acidophilus and Finegoldia magna, and from surgical site infection, E. lenta was most predominantly isolated, followed by P micra and L. acidophilus, in this order. Among anaerobic Gram-negative bacteria, the isolation rate of Bacteroidesfragilis was the highest from primary infections, followed by Bilophila wadsworthia, Bacteroides thetaiotaomicron, Bacteroides uniformis and Bacteroides vulgatus, and from surgical site infection, B. fragilis was most predominantly isolated, followed by Bacteroides caccae, B. thetaiotaomicron, Bacteroides ovatus and B. wadsworthia, in this order. In this series, vancomycin-resistant MRSA (methicillin-resistant Staphylococcus aureus), vancomycin-resistant Enterococcus spp. and multidrug-resistant P. aeruginosa were not observed. We should carefully follow up B. wadsworthia which was resistant to various antimicrobial agents, and also Bacteroides spp. which was resistant to many β-lactams.

- Abstract
Bacteria isolated from infections in abdominal surgery during the period from April 2007 to March 2008 were investigated in a multicenter study in Japan, and the following results were obtained. In this series, 707 strains including 24 strains of Candida spp. were isolated from 181 (79.0%) of 229 patients with surgical infections. Three hundred and ninety-five strains were isolated from primary infections, and 288 strains were isolated from postoperative infections. From primary infections, anaerobic Gram-negative bacteria were predominant, followed by aerobic Gram-negative bacteria, while from postoperative infections aerobic Gram-positive bacteria were predominant, followed by anaerobic Gram-negative bacteria. Among aerobic Gram-positive bacteria, the isolation rate of Enterococcus spp. was highest, followed by Streptococcus spp., and Staphylococcus spp. in this order, from primary infections, while Enterococcus spp. was highest, followed by Staphylococcus spp. from postoperative infections. Among aerobic Gram-negative bacteria, Escherichia coli was the most predominantly isolated from primary infections, followed by Klebsiella pneumoniae, Pseudomonas aeruginosa and Enterobacter cloacae, in this order, and from postoperative infections, P. aeruginosa was most predominantly isolated, followed by E. cloacae, E. coli and K. pneumoniae. Among anaerobic Gram-positive bacteria, the isolation rate of Parvimonas micra was the highest from primary infections, followed by Streptococcus constellatus and Gemella morbillorum, and from postoperative infections, Anaerococcus prevotii was most predominantly isolated. Among anaerobic Gram-negative bacteria, the isolation rate of both Bacteroides fragilis and Bilophila wadsworthia were the highest from primary infections, followed by Bacteroides thetaiotaomicron and Campylobacter gracilis, and from postoperative infections, B. thetaiotaomicron was most predominately isolated, followed by B. fragilis, Bacteroides caccae and B. wadsworthia in this order. In this series, we noticed no vancomycin-resistant Gram-positive cocci, nor multidrug-resistant P aeruginosa. There were nine strains of coagulase-negative Staphylococci which show higher MIC against teicoplanin more than 4 gg/mL, but all of them had good susceptibilities against various anti-MRSA antibiotics. We should carefully follow up B. wadsworthia which was resistant to various antibiotics, and also Bacteroides spp. which was resistant to many beta-lactam antibiotics.

- Abstract
Tendency of isolated bacteria from infections in abdominal surgery during the period from April 2006 to March 2007 were investigated in a multicenter study in Japan, and the following results were obtained. In this series, 474 strains including 23 strains of Candida spp. were isolated from 170 (75.2%) of 226 patients with surgical infections. Two hundred and twenty-six strains were isolated from primary infections, and 224 strains were isolated from postoperative infections. From primary infections, anaerobic Gram-negative bacteria were predominant, followed by aerobic Gram-negative bacteria, while from postoperative infections aerobic Gram-positive bacteria were predominant, followed by anaerobic Gram-negative bacteria. Among aerobic Gram-positive bacteria, the isolation rate of Staphylococcus spp. was higher from postoperative infections, while Enterococcus spp. was higher from primary infections. Among aerobic Gram-negative bacteria, Escherichia coli was the most predominantly isolated from primary infections, followed by Klebsiella pneumoniae, Enterobacter cloacae and Pseudomonas aeruginosa, in this order, and from postoperative infections, P. aeruginosa was the most predominantly isolated, followed by E. coli and E. cloacae. Among anaerobic Gram-negative bacteria, the isolation rate of Bilophila wadsworthia was the highest from primary infections, followed by Bacteroides fragilis and from postoperative infections, B. fragilis was most predominately isolated, followed by Bacteroides caccae, Bacteroides thetaiotaomicron and B. wadsworthia in this order. In this series, we noticed no methicillin-resistant Staphylococcus aureus, nor multidrug-resistant P. aeruginosa. There were three strains of methicillin-resistant coagulase-negative Staphylococcus aureus, but all of them had good susceptibilities against various anti-MRSA antibiotics. We should carefully follow up B. wadsworthia.

- Abstract
Purpose: This study was designed to investigate the influence of "The diagnosis and treatment guidelines for deep mycosis" (hereinafter referred to as "the Guidelines") in Japan on the diagnosis and treatment of deep mycosis in the field of emergency and critical care medicine and their influences on patient outcomes., Methods: In patients (administered antimycotics or who had pyrexia showing no response to any antimicrobial drug) medically examined and suspected of having had a fungal infection at 15 medical institutions throughout Japan, participating in the Japanese Society for the Study of Critical Care for Mycosis during the period from May 2003 through August 2004 and with facilities for emergency and critical care medicine, patient background, risk factors, awareness of the Guidelines, diagnosis, contents of treatment, and outcomes were investigated. On the basis of the data pertaining to these items, whether or not the course of diagnosis and treatment for each patient conformed to the diagnosis and treatment recommended in the Guidelines was retrospectively evaluated. Whether or not the treatment had been conducted with antimycotics and the doses recommended in the Guidelines, was also investigated, and outcomes were assessed according to conformity and non-conformity to the Guidelines., Results: Of the 125 subjects assessed, 55.2% responded that they were conscious of the Guidelines. The subjects who had indications for the Guidelines included 10 (8.0%), who were definitely diagnosed as having had mycosis, 3 (2.4%) who were diagnosed as having had clinical mycosis, and 35 (28.0%) who were suspected of having had mycosis. In the remaining 77 (61.6%), whether their conditions were non-mycosis or mycosis could not be determined. The treatment conformed to the Guidelines in 25 subjects (20.0%), but did not in 23 (18.4%). In 77 subjects (61.6%), whether or not the condition had been mycosis could not be determined. The number of the patients in whom whether or not the treatment had conformed to the Guidelines could be determined was decreased and there was a marked influence of administration of antimycotics, which was based on the assumption that "pyrexia with no response to broad-spectrum antimicrobial drugs persists for at least 3 days" in the Guidelines, was given as the reason. There was no significant difference in outcomes (survival or death) at the end of the study based on whether or not the subject had been conscious of the Guidelines or whether or not the contents of treatment conformed to the Guidelines. The number of days that treatment was administered in the ICU was greater in the treatment conforming to the Guidelines than in that not conforming to the Guidelines, but the difference did not reach statistical significance., Conclusion: The Guidelines were recognized at the time of treatment by more than half of the patients registered, but there were actually only a few patients in whom the diagnosis and treatment conformed to the Guidelines. One possible reason is considered to be that there was a marked influence of one item of the Guidelines, i.e. "pyrexia without response to broad-spectrum antimicrobial drugs persists for at least 3 days", in patients with suspected mycosis, who receive empirical treatment, in terms of the reason. Future examination is considered to be needed regarding the validity of this item.

- Abstract
Purpose: This study was designed to elucidate the present situation of diagnosis and treatment for mycosis in the field of emergency and critical care medicine following presentation of the diagnosis and treatment guidelines for deep mycosis (in February, 2003)., Methods: In patients (administered antimycotics or who have pyrexia showing no response to any antimicrobial drug), medically examined and suspected of having had a fungal infection at 15 medical institutions throughout Japan, participating in the Japanese Society for the Study of Critical Care for Mycosis during the period from May 2003 through August 2004 and with facilities for emergency and critical care medicine, patient background, risk factors, contents of treatment, and patient outcomes were totaled and assessed., Results: The subjects of this assessment were 125 patients consisting of 87 (69.6%) men and 38 (30.4%) women. Their mean age was 59.6 years, and 36.8% were 70 years of age or older. Intravascular catheterization was conducted in 78.4% of the 125 subjects. Antimycotics were administered to 89 patients, and the frequencies of fluconazole (FLCZ) for the initial administration and during the period of data registration were the highest (74.2% and 80.9%, respectively). The frequency with which a carbapenem antimicrobial drug was administered prior to antimycotics was the highest (41.6%). Blood culture was conducted in 85 patients (68.0%), monitoring culture in 108 (86.4%). Fungi were detected in 10 patients (11.8%) with blood culture and 72 (66.7%) with monitoring culture. The frequency of Candida albicans detection was the highest, 50.0% (5/10), with blood culture. With monitoring culture as well, the frequency of C. albicans detection was the highest, 55.6% (40/72). Alleviation of fever at the completion of registration was recognized in 65.6%. The survival rates at the completion of and at 28 days after the start of data registration of were 78.4% and 69.6%, respectively., Conclusion: Many patients in the field of emergency and critical care medicine had risk factors for deep mycosis; 11.8% and 66.7% of our 125 subjects were positive on blood and monitoring cultures, respectively. The majority of the fungi detected belonged to the Candida group, and FLCZ was the most frequently used antimycotic.

- Abstract
Tendency of isolated bacteria from infections in abdominal surgery during the period from April 2005 to March 2006 were investigated in a multicenter study in Japan, and the following results were obtained. In this series, 384 strains including 18 strains of Candida spp. were isolated from 161 (70.3%) of 229 patients with surgical infections. One hundred and ninty-five strains were isolated from primary infections, and 171 strains were isolated from postoperative infections. From primary infections, aerobic Gram-negative bacteria and aerobic Gram-positive bacteria were predominant, while aerobic Gram-positive bacteria were predominant from postoperative infections. The isolation rate of aerobic Gram-positive bacteria, such as Enterococcus spp. and Staphylococcus aureus were higher from both types of infections. Among anaerobic Gram-positive bacteria, the isolation rate of Peptostreptococcus spp. was the highest from both types of infections. Among aerobic Gram-negative bacteria, Escherichia coli was the most predominantly isolated from primary infections, followed by Pseudomonas aeruginosa, Klebsiella spp. in this order, and from postoperative infections, E. coli was the most predominantly isolated, followed by Klebsiella pneumoniae and P. aeruginosa. Among anaerobic Gram-negative bacteria, the isolation rate of Bacteroides fragilis group was the highest from both primary and postoperative infections. In this series, we noticed no vancomycin-resistant Gram-positive cocci, nor multidrug-resistant P. aeruginosa. But cefazolin-resistant E. coli producing extended spectrum fl-lactamase was seen in 5.0 per cents. We should be carefully followed up the facts that the increasing isolation rates of B. fragilis group and Bilophila wadsworthia which were resistant to both penicillins and cephems.

- Abstract
Tendency of isolated bacteria from infections in general surgery during the period from April 2004 to March 2005 were investigated in a multicenter study in Japan, and the following results were obtained. In this series, 645 strains including 17 strains of Candida spp. were isolated from 226 (79.0%) of 286 patients with surgical infections. Three hundred and seventeen strains were isolated from primary infections, and 345 strains were isolated from postoperative infections. From primary infections, anaerobic Gram-positive bacteria and anaerobic Gram-negative bacteria were predominant, while aerobic Gram-positive bacteria were predominant from postoperative infections. The isolation rate of aerobic Gram-positive bacteria, such as Enterococcus spp. and Staphylococcus aureus were higher from both types of infections. Among anaerobic Gram-positive bacteria, the isolation rate of Peptostreptococcus spp. was the highest from both types of infections. Among aerobic Gram-negative bacteria, Escherichia coli was the most predominantly isolated from primary infections, followed by Pseudomonas aeruginosa, Klebsiella pneumoniae and Citrobacter freundii in this order, and from postoperative infections, P. aeruginosa was the most predominantly isolated, followed by E. coli, E. cloacae, and K. pneumoniae. Among anaerobic Gram-negative bacteria, the isolation rate of Bacteroides fragilis group was the highest from both primary infections followed by Bilophila wadsworthia. While the isolation rate of B. fragilis group was also the highest from postoperative infections, the following bacteria were Bacteroides thetaiotaomicron and B. wadsworthia in this order. In this series, we noticed no vancomycin-resistant Gram-positive cocci, but a few strains of moderately arbekacin-resistant MRSA. Carbapenem-resistant P. aeruginosa but not multidrug-resistant was seen in 13.3 per cents. Also cefazolin-resistant E. coli probably producing extended spectrum beta-lactamase was seen in 7.0 per cents. We should be carefully followed up the facts that an increasing isolation rates of B. fragilis group and B. wadsworthia which were resistant to both penicillins and cephems.

- Abstract
Tendency of isolated bacteria from infections in general surgery during the period from April 2003 to March 2004 were investigated in a multicenter study in Japan, and the following results were obtained. In this series, 455 strains including 14 strains of Candida spp. were isolated from 191(75.2%) of 254 patients with surgical infections. Two hundred and thirty-nine strains were isolated from primary infections, and 216 strains were isolated from postoperative infections. From primary infections, anaerobic Gram-positive bacteria and aerobic Gram-negative bacteria were predominant, while aerobic Gram-positive bacteria were predominant from postoperative infections. The isolation rate of aerobic Gram-positive bacteria, such as Enterococcus spp. and Staphylococcus aureus were higher from both types of infections. Among anaerobic Gram-positive bacteria, the isolation rate of Peptostreptococcus spp. was the highest from both types of infections. Among aerobic Gram-negative bacteria, Escherichia coli was the most predominantly isolated from primary infections, followed by Klebsiella pneumoniae, Enterobacter cloacae and Pseudomonas aeruginosa in this order, and from postoperative infections, E. coli was the most predominantly isolated, followed by P. aeruginosa, E. cloacae, and K. pneumoniae. Among anaerobic Gram-negative bacteria, the isolation rate of Bacteroides fragilis group was the highest from both types of infections. The isolation rate of anaerobic Gram-positive bacteria from primary infections and that of aerobic Gram-positive bacteria from postoperative infections were high in the last several years. In this series, we noticed no vancomycin-resistant Gram-positive cocci, but a few strains of moderately arbekacin-resistant MRSA. Carbapenm-resistant P. aeruginosa was seen in less than 10 per cents. Last year we noticed that there were cefazolin-resistant E. coli producing extended spectrum beta-lactamase, but there was no highly cefazolin-resistant E. coli in this year. In the next series, increase of both anaerobic bacteria and Enterococcus spp. should be carefully followed up.

- Abstract
Systemic inflammatory response syndrome (SIRS) is defined by four simple clinical and laboratory indices and now widely accepted for diagnosing sepsis. However, since the SIRS criteria include patients with a wide range of severity, other parameters are necessary to evaluate the severity and outcome of the patients. In this review, we discussed several methods to estimate the severity of SIRS, such as number of positive SIRS indices among four, duration of SIRS, plasma IL-6 and procalcitonin, etc.

- Abstract
The concept of systemic inflammatory response syndrome (SIRS) was introduced in 1992 to define and objectively diagnose sepsis. Over the last decade, the definition of sepsis has been used for inclusion criteria of multicenter trials to develop innovative therapies of sepsis. With the recent understanding of the pathogenetic mechanisms of sepsis, many drugs have been tested, but only two drugs (activated protein C and neutrophil-elastase inhibitor) have been approved for clinical use in sepsis or SIRS. Further understanding of basic pathophysiology of SIRS and sepsis holds promise to develop a new therapeutic strategy to improve survival of patients with SIRS and sepsis.

- Abstract
Tendency of isolated bacteria from infections in general surgery during the period from April 2002 to March 2003 were investigated in a multicenter study in Japan, and the following results were obtained. In this series, 334 strains were isolated from 131 (75.3%) of 174 patients with surgical infections. One hundred and seventy-one strains were isolated from primary infections, and 163 strains were isolated from post-operative infections. From primary infections, anaerobic Gram-positive bacteria were predominant, while aerobic Gram-positive bacteria were predominant from postoperative infections. Among aerobic Gram-positive bacteria, although the isolation rate of Staphylococcus aureus was the highest, followed by that of Enterococcus faecalis from primary infections, the isolation rate of E. faecalis was the highest from postoperative infections. Among anaerobic Gram-positive bacteria, the isolation rate of Peptostreptococcus spp. was the highest from both types of infections. Among aerobic Gram-negative bacteria, Escherichia coli was the most predominantly isolated from primary infections, followed by Klebsiella pneumoniae and Pseudomonas aeruginosa in this order, and from postoperative infections, E. coli was the most predominantly isolated, followed by P. aeruginosa, Enterobacter cloacae, and Citobacter freundii. Among anaerobic Gram-negative bacteria, the isolation rate of Bacteroides fragilis group was the highest from both types of infections. The isolation rate of aerobic Gram-negative bacteria from primary infections and that of aerobic Gram-positive bacteria from postoperative infections were high in the last several years. We noticed no vancomycin-resistant Gram-positive cocci nor P. aeruginosa producing metallo-beta-lactamase. But we noticed cefazolin-resistant E. coli probably producing extended spectrum beta-lactamase.

- Abstract
In April 2004, a new training system for physicians and surgeons will take effect in Japan. All medical graduates, after passing the National Medical Practitioners Examination, are to complete a two-year compulsory clinical training program, which includes rotations to the clinical services of internal medicine, surgery, emergency medicine, pediatrics, obstetrics and gynecology, psychiatry, and regional primary practice. Hospitals offering training programs must be approved by the Ministry of Health, Welfare and Labor. The trainees will be provided with reasonable stipends. In accordance with the introduction of new system, the current surgical training system is to be renovated and the terms for surgical trainees to be eligible for surgical specialty boards must be reviewed.

- Abstract
Tendency of isolated bacteria from infections in general surgery and their antimicrobial susceptibilities during the period from April 2000 to March 2001 were investigated in a multicenter study in Japan, and the following results were obtained. The number of cases investigated as objectives was 234 for one year. A total of 388 strains (136 strains from primary infections and 252 strains from postoperative infections) were isolated from 165 cases (70.5% of total cases). In primary infections, anaerobic Gram-positive bacteria were predominant, while from postoperative infections, aerobic Gram-positive bacteria were predominant. Among aerobic Gram-positive bacteria, the isolation rate of Enterococcus faecalis was the highest, followed by that of Staphylococcus aureus from postoperative infections. Among anaerobic Gram-positive bacteria, the isolation rate of Peptostreptococcus spp. was the highest from both types of infections. Among aerobic Gram-negative bacteria, Escherichia coli was the most predominantly isolated from primary infections, followed by Klebsiella pneumoniae and Pseudomonas aeruginosa in this order, and from postoperative infections, P. aeruginosa was the most predominantly isolated, followed by Enterobacter spp. and Klebsiella spp. Among anaerobic Gram-negative bacteria, the isolation rate of Bacteroides fragilis group was the highest from both types of infections. There was no vancomycin-resistant S. aureus nor Enterococcus spp. Among anaerobic bacteria, there were many resistant strains against penicillins and cephems with MICs higher than 100 micrograms/ml, and the same trend was observed among other Bacteroides spp. and Prevotella spp.

- Abstract
The annual multicenter studies on isolated bacteria from infections in general surgery and their antimicrobial susceptibility have been conducted in Japan since July 1982. In this paper, the results obtained in the academic year 1999 (from April 1999 to March 2000) have been summarized. Two hundred seven cases were investigated, and 411 strains were isolated from 169 cases (81.6%). Of those strains, 184 and 227 strains were from primary infections and postoperative infections, respectively. In primary infections, the isolation rates of anaerobes, Streptococcus spp., and Escherichia coli were higher than in postoperative infections, while in postoperative infections, those of Gram-positive aerobes were higher than in primary infections. Staphylococcus aureus were most frequently isolated among Gram-positive aerobes, Peptostreptococcus prevotii among Gram-positive anaerobes, E. coli among Gram-negative aerobes, and Bacteroides fragilis among Gram-negative anaerobes. In primary infections, the percentage of Gram-negative aerobes, which gradually increased by the year 1998, decreased in the year 1999. The percentage of Gram-negative anaerobes increased, while that of Gram-negative bacteria was equivalent to that in the last year. In postoperative infections, the percentage of Gram-negative anaerobes, which continuously increased after the year 1990, decreased, while that of Gram-positive aerobes, which decreased in the last year, increased. Methicillin-resistant S. aureus accounted for 70.7% of S. aureus (41 strains). Either the number of strain or the percentage of MRSA decreased. The susceptibilities of E. coli and Klebsiella pneumoniae decreased against third and forth generation cephems, oxacephems, and monobactams. The susceptibilities of P. aeruginosa to carbapenems tend to decrease after the year 1997. S. aureus showed good susceptibilities to the tested drugs including arbekacin, vancomycin, and teicoplanin.
