RESUMEN
Anesthesia of the horn bud for calf disbudding commonly is attained by injection of local anesthetic over branches of the cornual nerve, with anesthesia achieved in 3 to 20 min. With experienced and trained staff, this method is effective in 88 to 100% of calves. Variability in response and time of onset can compromise calf welfare if calves are disbudded before anesthesia is attained. Proposed legislative reliance on effective local anesthetic as the minimal method of pain relief for calves at disbudding means that administration of local anesthetic must achieve a repeatable level and rapid onset of analgesia. We describe an alternative method of local anesthesia administration that uses local site infiltration of anesthetic over the horn bud. However, this method has not yet been scientifically validated. This study assessed differences between disbudding using the cornual nerve block and disbudding with local anesthesia administered by local site infiltration. Efficacy of local anesthesia was assessed at 30-s intervals after administration by absence of reaction to 3 consecutive needle pricks over the horn buds. Behavior indicating pain was assessed during disbudding and scored from 0 to 3. Calf behavior was also recorded for 3 h after disbudding. Accelerometer data loggers were fitted to each calf for 24 h before and after disbudding to assess lying and standing times. Median time to cutaneous desensitization for local infiltration was 60 s compared with 225 s for cornual nerve block, and the variance in time to desensitization was less with local infiltration. Calves disbudded under cornual block had a larger behavioral response (indicated by a graded aversive body reaction) than calves disbudded under local infiltration. A multivariable model predicted that the mean body reaction score would be 0.6 for calves disbudded under local infiltration and 1.2 for calves disbudded under cornual block. There was no difference in any behaviors between the treatment groups in the 3 h after disbudding. Method of analgesia had no effect on lying time over the 24 h after disbudding. In this study, local infiltration was at least as effective in providing analgesia for disbudding as the cornual nerve block. Our results suggest that a more consistent, effective level of analgesia during disbudding was achieved using local infiltration and that there was no difference in postoperative expressions of pain.

In October 2007, a governmental 3-year target to reduce Clostridium difficile infection (CDI) by 30%, with financial penalties levied for failure, was introduced in England. This target was met within just 1 year, leading to speculation of 'gaming', with hospitals empirically treating possible CDI in the absence of a microbiological diagnosis, to avoid having to report confirmed cases. An analysis of aggregate mandatory data on levels of testing for C. difficile toxin showed little evidence of a fall in testing during the steepest infection rate reductions, suggesting that this was not a major factor in the decline in CDI.

Antimicrobial resistance (AMR) has become a global problem for health care services, with fewer antimicrobials entering the market and some pathogenic organisms becoming resistant to commonly used antimicrobials. Antimicrobial stewardship (AS), including evidence-based standard setting, education and communication, and audits of practice, has become a key method of preventing the rise in the rise in AMR. Data on antibiotic consumption are often obtained through prospective and retrospective point prevalence audits of antibiotic usage, but such studies are very resource intensive and only provide a snapshot of consumption. The objective of the study reported here was to examine longitudinal total antibacterial usage at a national level and cross-sectional usage at an individual hospital trust level using a commercial database that captures antimicrobial prescribing from at least 99% of English hospital Trusts.

INTRODUCTION: In order to support decisions and analyze outcomes, the Spanish Health System has shown a great interest in developing data bases and high quality information systems. Nevertheless the use of these data bases are limited, not very systematized and, some times, their accessibility may be difficult. MATERIAL AND METHODS: We describe in this review the experience in using the Institute for Clinical Evaluative Science (ICES, Ontario, Canada) as an efficient model to improve the usefulness of these data bases. RESULTS: Under restrictive conditions of confidentiality and privacy, the ICES has the legal capacity to use several population based data bases, for research projects and reports. ICES's functional structure (with an administrative and scientific level) is an interesting framework since it guarantees its independent and economic assessment. DISCUSSION: To date, its scientific production has been high in many areas of knowledge and open to those interested, with points of view of many health care professionals (including management), for whom the quality of research is of the ultimate importance, to be able to access these resources.

OBJECTIVES: To use national laboratory surveillance data to determine whether pathogens responsible for neonatal bacteraemia were sensitive to nationally recommended antibiotic regimens. DESIGN: All reports of neonatal bacteraemia received by the Health Protection Agency's voluntary surveillance scheme in England and Wales from January 2006 until March 2008, were extracted from the database. Organisms were ranked by frequency, and proportions susceptible to antimicrobials recommended for empirical treatment of neonatal sepsis were determined. RESULTS: There were 1516 reports of bacteraemia for neonates <48 h old (early-onset) and 3482 reports for neonates 2-28 days old (late-onset). For early-onset bacteraemia, group B streptococcus (GBS) was the most frequent pathogen (31%) followed by coagulase-negative staphylococci (CoNS; 22%), non-pyogenic streptococci (9%) and Escherichia coli (9%). For late-onset bacteraemia, CoNS were isolated most frequently (45%), followed by Staphylococcus aureus (13%), Enterobacteriaceae (9%), E coli (7%) and GBS (7%). More than 94% of organisms (early-onset) were susceptible to regimens involving combinations of penicillin with either gentamicin or amoxicillin, amoxicillin combined with cefotaxime or cefotaxime monotherapy. More than 95% of organisms (late-onset) were susceptible to gentamicin with either flucloxacillin or amoxicillin and amoxicillin with cefotaxime, but only 79% were susceptible to cefotaxime monotherapy. CONCLUSIONS: Current guidelines for empirical therapy in neonates with sepsis are appropriate. However, gentamicin-based regimens should be used in preference to cefotaxime-based treatments, because of lower levels of susceptibility to cefotaxime and the need to avoid exerting selective pressure for resistance. Surveillance data linked to clinical data should further inform rational antibiotic prescribing in neonatal units.

Oligella urethralis is an organism which is normally isolated as a commensal from the genitourinary tract. We describe the first two reported cases of CAPD-associated peritonitis caused by this organism. Both isolates were found to be resistant to ciprofloxacin, while relatively sensitive to a wide range of antimicrobial drugs. These findings indicate that this organism may be an opportunistic pathogen for CAPD patients, and that extensive ciprofloxacin usage provides a selection pressure for emergence of resistance.

Chancroid, an ulcerous disease of the genitalia caused by Haemophilus ducreyi, occurs rarely but regularly in Germany. Exact diagnosis is based on the clinical features and a direct smear, and in particular on cultivation of the organism, showing its unique macromorphological characteristics. The sensitivity of cultivation has increased due to the development of selective media for primary isolation. Resistance problems during the last decade meant that a change to new therapeutic strategies was unavoidable. The work presented here includes a case report and a review of the recent literature, it illustrates modern methods of diagnosis and treatment of Haemophilus ducreyi infections 100 years after the first description of the organism.
