[Tritrichomonas fetus: a new intestinal parasite in Swiss cats]

Recent reports identified Tritrichomonas fetus, the causative agent of bovine trichomonosis, in cats with large-bowel diarrhea in the US. Between July 2007 and August 2008, a total of 105 Swiss cats were tested for T. fetus with the InPouchTM culture system and/or PCR, whereof 27 (26%) yielded positive results. All positive cats were pedigree cats, whereof 22 (81%) were less than 1 year of age (median 5 months). 25 (93%) of these cats lived in multi-cat households, and all but one were kept indoor. The clinical picture was dominated by large bowel diarrhea with increased frequency of defecation and fresh blood and mucus. Furthermore, inflamed anus and fecal incontinence was common. 52% of the T. fetus-positive cats were tested positive for Giardia before, but the treatment with fenbendazole or metronidazole only temporarily alleviated the clinical signs. The treatment with 30 mg/kg of ronidazole q12h p.o. was successful in all but 1 cat with only minor transient adverse effects in 3 cats. In conclusion, T. fetus has to be considered an important causative agent of large bowel diarrhea in cats in Switzerland, especially in young indoor pedigree cats.

Measuring the bending of asymmetric planar EAP structures

The geometric characterization of low-voltage dielectric electro-active polymer (EAP) structures, comprised of nanometer thickness but areas of square centimeters, for applications such as artificial sphincters requires methods with nanometer precision. Direct optical detection is usually restricted to sub-micrometer resolution because of the wavelength of the light applied. Therefore, we propose to take advantage of the cantilever bending system with optical readout revealing a sub-micrometer resolution at the deflection of the free end. It is demonstrated that this approach allows us to detect bending of rather conventional planar asymmetric, dielectric EAP-structures applying voltages well below 10 V. For this purpose, we built 100 μm-thin silicone films between 50 nm-thin silver layers on a 25 μm-thin polyetheretherketone (PEEK) substrate. The increase of the applied voltage in steps of 50 V until 1 kV resulted in a cantilever bending that exhibits only in restricted ranges the expected square dependence. The mean laser beam displacement on the detector corresponded to 6 nm per volt. The apparatus will therefore become a powerful mean to analyze and thereby improve low-voltage dielectric EAP-structures to realize nanometer-thin layers for stack actuators to be incorporated into artificial sphincter systems for treating severe urinary and fecal incontinence.

Complete continence after botulinum neurotoxin type A injections for refractory idiopathic detrusor overactivity incontinence: patient-reported outcome at 4 weeks

Objective improvement following intradetrusor injections of botulinum neurotoxin type A (BoNTA) is well documented. Although patient-related outcome measures are highly recommended for monitoring overactive bladder symptoms, no study before has dealt with the question of patient-reported complete continence after BoNTA treatment using validated questionnaires.

An adjustable sling in the management of recurrent urodynamic stress incontinence after previous failed midurethral tape

The aim of this prospective study was to evaluate the feasibility and outcome of an adjustable sling system AMI in patients with recurrent urinary stress incontinence after failed suburethral sling insertion.

Fecal calprotectin correlates more closely with the Simple Endoscopic Score for Crohn's disease (SES-CD) than CRP, blood leukocytes, and the CDAI

Studies evaluating the correlation between the widely used Simple Endoscopic Score for Crohn's disease (SES-CD) and noninvasive markers are scarce. The aim of this study was to evaluate the correlation between the SES-CD and fecal calprotectin, C-reactive protein (CRP), blood leukocytes, and the Crohn's disease activity index (CDAI).

[Urinary incontinence]

Incontinence is a common age-dependent and increasing problem in women that may mainly present as stress incontinence, overactive bladder, mixed incontinence or other forms. A thorough history, gynaecological and neurological examination and urinalysis as initial step will lead to the diagnosis and treatment. If midstream urine is difficult to receive, a catheter urine will be easy to obtain. Further investigations as urodynamics, cystoscopy and ultrasound may be required. As initial step, stress incontinence should be treated with physiotherapy and pelvic floor exercises, if not successful with operations as suburethral slings. Slings have good long-term success rates of approximately 85 % with a low morbidity and can even be inserted under local anaesthetic. The treatment of idiopathic overactive bladder consists of bladder training, a behavioural therapy, and mainly anticholinergics. Anticholinergics may cause side effects particularly in the elderly who are under several medications that may add anticholinergic effects as antidepressants, antibiotics or antihistaminics.

Effect of treatment delay on disease severity and need for resuscitation in porcine fecal peritonitis.

Early treatment in sepsis may improve outcome. The aim of this study was to evaluate how the delay in starting resuscitation influences the severity of sepsis and the treatment needed to achieve hemodynamic stability.

Fecal carriage of extended-spectrum beta-lactamase-producing Enterobacteriaceae in swine and cattle at slaughter in Switzerland

During the past decade, extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae have become a matter of great concern in human medicine. ESBL-producing strains are found in the community, not just in hospital-associated patients, which raises a question about possible reservoirs. Recent studies describe the occurrence of ESBL-producing Enterobacteriaceae in meat, fish, and raw milk; therefore, the impact of food animals as reservoirs for and disseminators of such strains into the food production chain must be assessed. In this pilot study, fecal samples of 59 pigs and 64 cattle were investigated to determine the occurrence of ESBL-producing Enterobacteriaceae in farm animals at slaughter in Switzerland. Presumptive-positive colonies on Brilliance ESBL agar were subjected to identification and antibiotic susceptibility testing including the disc diffusion method and E-test ESBL strips. As many as 15.2% of the porcine and 17.1% of the bovine samples, predominantly from calves, yielded ESBL producers. Of the 21 isolated strains, 20 were Escherichia coli, and one was Citrobacter youngae. PCR analysis revealed that 18 strains including C. youngae produced CTX-M group 1 ESBLs, and three strains carried genes encoding for CTX-M group 9 enzymes. In addition, eight isolates were PCR positive for TEM beta-lactamase, but no bla(SHV) genes were detected. Pulsed-field gel electrophoresis showed a high genetic diversity within the strains. The relatively high rates of occurrence of ESBLproducing strains in food animals and the high genetic diversity among these strains indicate that there is an established reservoir of these organisms in farm animals. Further studies are necessary to assess future trends.

EAU guidelines on surgical treatment of urinary incontinence

The European Association of Urology (EAU) guidelines on urinary incontinence published in March 2012 have been rewritten based on an independent systematic review carried out by the EAU guidelines panel using a sustainable methodology. OBJECTIVE: We present a short version here of the full guidelines on the surgical treatment of patients with urinary incontinence, with the aim of dissemination to a wider audience. EVIDENCE ACQUISITION: Evidence appraisal included a pragmatic review of existing systematic reviews and independent new literature searches based on Population, Intervention, Comparator, Outcome (PICO) questions. The appraisal of papers was carried out by an international panel of experts, who also collaborated in a series of consensus discussions, to develop concise structured evidence summaries and action-based recommendations using a modified Oxford system. EVIDENCE SUMMARY: The full version of the guidance is available online (www.uroweb.org/guidelines/online-guidelines/). The guidance includes algorithms that refer the reader back to the supporting evidence and have greater accessibility in daily clinical practice. Two original meta-analyses were carried out specifically for these guidelines and are included in this report. CONCLUSIONS: These new guidelines present an up-to-date summary of the available evidence, together with clear clinical algorithms and action-based recommendations based on the best available evidence. Where high-level evidence is lacking, they present a consensus of expert panel opinion.

EAU guidelines on assessment and nonsurgical management of urinary incontinence

The previous European Association of Urology (EAU) guidelines on urinary incontinence comprised a summary of sections of the 2009 International Consultation on Incontinence. A decision was made in 2010 to rewrite these guidelines based on an independent systematic review carried out by the EAU guidelines panel, using a sustainable methodology.
