Abstract
SummaryThe object of this retrospective clinical study was to evaluate the efficacy of arthroscopic lavage and debridement, followed by intra-articular implantation of resorbable gentamicin-impregnated collagen sponges (GICS) for treatment of chronic (≥ seven days) septic arthritis in cattle. Fourteen cattle suffering from chronic septic monarthritis refractory to previous treatment were included in this study. Age ranged from one month to 7 years (mean = 34 months) and bodyweight from 58 to 640 kg (mean = 422 kg). The degree of lameness and characteristics of synovial fluid were evaluated before and at days #10 and 20 after the initial operation. The standard surgical procedure consisted of arthroscopic “through-and-through” lavage of the affected joint with a physiological Ringer’s solution, partial synovectomy, and curettage of the articular cartilage when considered necessary, followed by the intra-articular administration of GICS. The aftercare included administration of procaine penicillin, phenylbutazone, and stall confinement. The progress of the cases was monitored at three to 24 months after the initial operation.The tarsocrural joint was affected in six cases, the antebrachiocarpal joint in five and the metacarpophalangeal joint in three cases. The degree of lameness, total nucleated cell count and total protein of synovial fluid significantly (P <.05) decreased within 10 days after the operation. Treatment was successful in 12 of 14 animals (86%). It was therefore concluded that the implantation of GICS after routine “throughand- through” lavage is a valuable alternative technique for the treatment of chronic septic arthritis in cattle. A subsequent second operation for implant removal was not necessary, as GICS are fully absorbable. The tarsocrural joint is associated with the least favourable prognosis of the joints treated in this study.The efficacy of arthroscopic “through-and-through” lavage and debridement, followed by intra-articular implantation of absorbable gentamicin-impreg-nated collagen sponges (GICS) for treatment of chronic (≥ seven days) septic arthritis in cattle was evaluated. Treatment was successful in 12 of 14 cattle (86%). This suggests that the described technique is a valuable alternative to established treatment regimens for prolonged intra-articular administration of gentamicin. When compared to gentamicin-impregnated polymethylmethacrylate beads, GICS have the advantage that a second operation for implant removal is not necessary.

Abstract
A 5-month old female Red-Holstein calf in poor condition was presented with a history of reduced appetite, respiratory disease and collapse. Clinical examination revealed an elevated heart rate and pronounced cyanosis of the mucous membranes. Heart and lung auscultation were normal. A complete blood count revealed profound polycythemia with severely increased values for packed cell volume, hemoglobin concentration and erythrocyte count. Cardiac ultrasonography revealed abnormal position of the great vessels with two arteries located in the right ventricle output tract and a high ventricular septum defect (VSD). Intracardial pressure and blood gas measurements confirmed pressure overload in the right heart, a left-to-right shunt through the VSD and a right-to-left-shunt leading to hypoxemia and secondary polycythemia. Based on poor prognosis, the animal was euthanized. Post-mortem examination confirmed the results of the further investigations conducted to determine the cause of polycythemia in this calf.

Abstract
BACKGROUND Standard guidelines for the management of dyslipidaemia are often not followed in general practice. The reasons for guideline non-adherence are not known. METHODS Charts of 1000 consecutive unselected patients of 20 general practitioners in northwestern Switzerland were reviewed. An independent committee of experienced study physicians checked the data and assessed the reasons for not measuring plasma cholesterol and for not treating dyslipidaemia as recommended by guidelines. RESULTS Complete data of 866 patients were studied. 29% of all patients qualified for secondary prevention. 6% had no additional cardiovascular risk factors (apart from cholesterol values), 24% had one and 41% had 2 or more additional cardio- vascular risk factors. Guidelines were followed in 44% of all cases and were not followed in 56%. In 37.5% of all cases we found diagnostic guideline non-adherence, and in 10% only treatment guideline non-adherence. 8.5% of all patients had both diagnostic and treatment non-adherence. The main reasons for diagnostic non-adherence were relevant comorbidity (45%) and GPs' belief that the risk did not require screening (42%). The main reasons for treatment non-adherence were GPs' belief that the risk did not require treatment (42%) and relevant comorbidity (38%). CONCLUSION More than half of all patients aged 35-80 years are not screened or treated according to current guidelines. The reasons are to an equal extent patient-related (relevant comorbidity) and physician-related (acceptance and knowledge of guidelines). These reasons should be considered when programmes to improve the quality of GPs' adherence to guidelines are implemented.

Abstract
Many hypertensive patients still have elevated blood pressure values despite antihypertensive treatment. However, which patients really do not respond to antihypertensive treatment? 41 primary care patients with treated essential arterial hypertension with office blood pressure > 140/90 mmHg received 24-hour ambulatory blood pressure measurement. The patients were categorized into a group with elevated blood pressure both in office (> or = 140/90 mmHg) and daytime ambulatory blood pressure measurement (> 135/85 mmHg) and into a group with False Non-Response to treatment (office blood pressure > or = 140/90 mmHg but normal daytime mean ambulatory blood pressure < 135/85 mmHg). Patients in the group with False NonResponse were significantly more likely to be female compared to patients with both office and ambulatory hypertension (67% vs. 23%, p = 0.009), whereas diabetes mellitus was a significant predictor of elevated blood pressure both in office and ambulatory measurement (7% vs. 39%, p = 0.033). False-Non-Response is common in primary care patients treated for hypertension. These patients have normal ambulatory BP values despite elevated office BP values. Female gender and absence of diabetes mellitus are significant predictors of False Non-response to antihypertensive treatment.

Abstract
Guidelines for primary prevention of cardiovascular disease recommend a management based on global cardiovascular risk calculated with prediction rules. While cardiovascular prediction rules are applied as a tool to estimate risk, Guidelines describe which consequences to be drawn based on this risk information. We performed a workshop to discuss open questions for application of prediction rules in primary care. Technical aspects may not be a problem, however, additional barriers for application in daily routine exist. First, accuracy of risk estimation is unclear for some of the prediction rules. Second, risk factors, which are intuitively relevant (like obesity), are lacking in most of the prediction rules. Third, differences between guidelines and prediction rules are sometimes not clear for the general physician. In this article we want to answer the most important questions, which have been discussed during the workshop.

Abstract
In order to establish reference values for blood parameters of South American camelids in Switzerland, 273 blood samples were collected from 141 llamas and 132 alpacas. These animals were classified in three categories (young animals < six months, adult females and males). Forty-one parameters were measured (red blood cell count, white blood cell count, electrolytes, metabolites and enzymes). Significant differences between llamas and alpacas were evident for 26 parameters. This study also showed that differences between young animals, females and males must be taken into consideration. A comparison of blood values with the results of fecal analysis for parasite eggs showed that an infestation with Dicrocoelium dendriticum was associated with elevated activity of two liver enzymes (GLDH and gamma-GT) in the serum. In contrast, no differences were found in the results of blood analyses between animals shedding eggs of gastrointestinal strongyles or not.

Abstract
Zusammenfassung
Gegenstand und Ziel: Das Ziel dieser Arbeit war, Referenzwerte für die hämatologischen und biochemischen Parameter für die Spezies Esel zu bestimmen. Die bis heute bekannten Arbeiten basieren auf inhomogenen Populationen oder sie berücksichtigen nur eine kleine Anzahl Tiere.Material und Methode: Die untersuchte Population bestand aus 46 Eseln, die an einer Zuchtschau in Deutschland teilgenommen hatten. Sie waren gesund und in gutem bis sehr gutem Pflegezustand. Die durchgeführten Bestimmungen umfassten eine vollständige Liste der in der klinischen Diagnostik verwendeten Parameter. Für jeden Wert ist der Referenzbereich mit dem Median und den Perzentilen 5-95% und 2,5-97,5% angegeben.Ergebnisse: Die hämatologischen Untersuchungen zeigten, dass Esel weniger, aber größere Erythrozyten besitzen als Pferde und dass sie eine höhere Anzahl Leukozyten aufweisen, wobei hier auch das Verhältnis Neutrophile/Lymphozyten gegenüber Pferden abweicht. Esel haben mehr Lymphozyten als Neutrophile. Zudem liegt die Zahl der Eosinophilen höher als bei Pferden. In der klinischen Chemie ergaben sich für Kreatinin, Gesamtbilirubin und Eisen niedrigere Werte als bei Pferden.Schlussfolgerung und klinische Relevanz: Die Unterschiede zeigen, dass die Referenzbereiche für Pferde nicht auf Esel anwendbar sind.

Abstract
Atrial fibrillation is a well-known heart disease in horses. The common therapy consists of administration of quinidine. More potent antiarrhythmic drugs have become available for human therapy and the use of these as alternatives to quinidine for equine antiarrhythmic therapy is a matter of interest. Amiodarone (AMD) is used in human medicine for treatment of many arrhythmias, including atrial fibrillation. Its disposition in horses has not yet been investigated. The purpose of this study was to measure the effect of single intravenous doses of amiodarone (5 and 7 mg/kg) on the surface electrocardiogram (ECG) of healthy minishetland ponies during the first 2 days after drug administration and to calculate pharmacokinetic parameters with a physiologically based pharmacokinetic model (PBPK) using amiodarone and desethylamiodarone (DAMD) plasma levels that were determined by high-performance liquid chromatography (HPLC). As expected for a K(+)-channel-blocker, the main effect on the measured ECG could be seen on the ventricular complex, as the QT interval and the T wave showed statistically significant alterations. The doses investigated were well tolerated clinically. Results from the pharmacokinetic model were found to compare well with literature data of rats, dogs, and humans. It showed a rapid distribution in the tissue, beginning with the rapidly perfused tissue, like the heart, followed by slowly perfused tissues, and finally an accumulation in fat. The half-life for total elimination was calculated to be 16.3 days with 99% eliminated by 97 days. The model predicts that approximately 96% of amiodarone is eliminated as desethylamiodarone in urine, 2% eliminated as desethylamiodarone in bile, and 2% as other metabolites.

Abstract
ZusammenfassungBei Haustieren und beim Menschen wurden verschiedene kongenitale zystische Leberveränderungen beschrieben. Im Folgenden wird über sieben Freiberger Fohlen im Alter von zwei bis vier Monaten berichtet, die eine kongenitale hepatische Fibrose und eine zystische Dilatation der Gallengänge aufwiesen. Die Kasuistiken sind den humanmedizinischen Caroli-Typ-II-Fällen sehr ähnlich. Mit einer Ausnahme wurde bei allen Tieren aufgrund der ausgeprägten ZNS-Symptomatik und der Laborbefunde mit deutlich positivem Leberprofil die Diagnose eines hepatozerebralen Syndroms gestellt. Die makroskopischen Leberveränderungen waren bei allen Fohlen identisch. Die Leber zeigte im Vergleich zu der gesunder Fohlen eine starke Vergrößerung und wies multiple mit Galle gefüllte Zysten unterschiedlicher Größe auf. Das durchschnittliche relative Lebergewicht (5%) war im Vergleich zu gesunden Fohlen (1,2-1,5%) stark erhöht. Histologisch zeigten alle Lebern eine diffuse portoportale Fibrose ohne Zerstörung der Grenzzone. Im Bindegewebe fanden sich dilatierte kleine Gallengänge, die miteinander in Verbindung standen. Herdförmig waren große Gallengangszysten zu sehen. Bei gesicherter Diagnose ist die Euthanasie angezeigt. Eine spontane Remission wird ausgeschlossen. Das Caroli-like Syndrome beim Pferd ist eine Erbkrankheit, die nur auf züchterischer Ebene bekämpft werden kann.

Abstract
The potential of electronic communication in medicine is assessed based on an analysis of a pilot project pertaining to internet based communication among referring and hospital physicians. Advantages of electronic data exchange in medicine pertain to speed and capacity for data transfer, availability of data and data integration, ultimately enabling consistent medical case management. Quality requirements of electronic communication of medical data are related to safety, availability, data integration, potential for case management and system qualities. Medical efficiency can be increased by use of electronic communication only if complex functions beyond the substitution of conventional mail by e-mail are implemented and an exhaustive use of the technology can be achieved.

Abstract
The population under study included young calves with pneumonia (group A, n = 13) and their controls (group B, n = 9), as well as older calves from which the lungs with (group C, n = 90) or without (group D, n = 10) lesions were collected after slaughter. Arcanobacterium pyogenes was the organism most commonly isolated from calves in group A (46%), followed by Haemophilus somnus (23%), Mannheimia haemolytica (15%), Streptococcus suis and Pasteurella multocida (7.7% each). Only S. suis (22%) and P. multocida (11%) were found in group B. P. multocida was isolated from 32% group C calves, H. somnus from 11%, A. pyogenes from 7.8%, M. haemolytica from 2.2% and S. suis from 1.1%. No specific pathogens were isolated in group D. Prevalence of Mycoplasma bovis infection was 69% in group A and 37% in group C. Ninety-eight strains were tested for resistAnce to antibiotics. Resistance to penicillin and ampicillin was present only in M. haemolytica (46%). High percentages of resistant strains were observed for streptomycin (48-100%), tetracycline (15-43%), sulfonamides alone (14-100%) or in combination with trimethoprim (0-100%). Therapeutic approaches to bacterial calf pneumonia in the area under study should be modified according to the isolated bacterial population, the observed antimicrobial resistances and the growing importance of Mycoplasma bovis.

Abstract
BACKGROUND The study aim was to analyse the diagnostic and therapeutic approach to selected infectious diseases, in particular with regard to the use of antibiotics, in the light of current guidelines and the problem of developing resistance. METHODS A questionnaire was sent to all physicians with a general or internal medicine practice in the Cantons Basel-Stadt and Basel-Landschaft, Switzerland. RESULTS Of 440 physicians, 286 (65%) took part in the study. The most frequent diagnoses of infection were cystitis (16.6%), flu-like syndrome (16.4%), acute bronchitis (12.3%), and tonsillopharyngitis (10.1%). The most frequent indications for antimicrobial therapy were cystitis (19.9%), acute sinusitis (14.1%), acute bronchitis (11.5%), and tonsillopharyngitis (9.2%). Macrolides (24.0%), aminopenicillins (22.6%), and fluoroquinolones (16.8%) were the most frequently prescribed antibiotics. CONCLUSIONS The majority of physicians diagnosed and treated according to rational principles. However, a few exceptions were found, e.g. omission of x-ray in the diagnosis of pneumonia (24%), the use of antibiotics in the treatment of viral diseases and antibiotic therapy for tonsillopharyngitis despite a negative rapid antigen detection test against group A streptococci (75%).

Abstract
Total serum immunoglobulin (Ig) E and A levels were analysed in 233 healthy dogs as basis for comparison with atopic dogs in future studies. They were measured by ELISA in a group of non- colonised dogs of various breeds (group A) and three groups of colonised dogs including one German Shepherd and two Beagle kennels (groups B-D). IgE levels from non-colonised dogs were significantly higher than the ones of German Shepherds and Beagles C (P<0.05). IgA levels were alike in all groups except for the German Shepherds which displayed the lowest levels. Age and sex were not identified as common significant cofactors for IgE and IgA levels in all groups and IgE levels correlated negatively with IgA only in non-colonised dogs. In conclusion, IgE and IgA levels seem to be mainly influenced by genetic background. Thus use of total serum IgE as a diagnostic tool in the atopic dogs required extensive family data and therefore appears most suitable for research purposes within specific, well defined dog populations.

Abstract
Serum and urine were taken from healthy dairy cattle from 22 different farms. 214 animals belonged to the Swiss Brown breed and 210 were crossbreds of Simmental-Red Holstein. The animals were given at least 70 g of sodium chloride with their daily feed ration. On 6 farms sodium chloride was offered ad libitum in form of licks, which was presumed to be sufficient for covering their needs. Concentrations of sodium (UR Na), potassium (UR K) and creatinine were analyzed from serum and urine and fractional excretion of Na and K was calculated. Concentrations of sodium and potassium in urine from all cows (mean +/- sd) was 60.9 +/- 44.7 mmol/l and 370.7 +/- 66.9 mmol/l respectively. The FE values were 0.954 +/- 0.939% for sodium and 173.1 +/- 54% for potassium. In 5.5% of the animals values for UR Na < 10 mmol/l were found. There were no significant differences, however, were found in sodium and potassium excretion among farms. Urine samples of at least 10 animals should be analyzed in order to have a reliable estimation of the supply with sodium chloride within a herd. Our results do not support the hypothesis that low sodium excretion would be a predisposing factor for Bovine Dilative Cardiomyopathy in Simmental-Red Holstein cattle.

Abstract
Concentrations of the cross-linked carboxyterminal telopeptide of type I collagen (ICTP) and osteocalcin (OC) have been determined in the serum of one hundred clinically healthy adult Draught or Warmblood horses. The correlation between these two markers has been evaluated and the influence of gender, age and type of horse described. No significant variations were observed between animals of different sex, but a significant inverse correlation (P < 0.0001) with age was observed for both measured parameters. After correction for age, serum levels of OC were found to be lower in Draught [adjusted least square mean (LSM) = 6.612 micrograms.L-1] than in Warmblood horses (adjusted LSM = 8.596 micrograms.L-1), whereas levels of ICTP were higher in Draughts (adjusted LSM = 8.035 micrograms.L-1) than in Warmbloods (adjusted LSM = 6.643 micrograms.L-1). A significant correlation (P < 0.0001) was observed between OC and ICTP. This correlation was stronger if the type of horse was taken into account in the statistical model. The ratio OC:ICTP was independent of gender and age. A higher OC:ICTP ratio in Warmbloods compared to the Draught horses might reflect a higher bone remodelling level of horses submitted to regular daily work. It was concluded that ICTP and OC are influenced by the type of horse, and probably reflect a physiological difference in bone remodelling between these animals.

Abstract
A new computerised ultrasound-based spirometry system according to Buess et al. (1995) modified by a double flow measurement facility was used to study pulmonary function in healthy horses and horses affected with subclinical and manifest chronic bronchiolitis (CB). The horses were first evaluated at rest without any medication. On another occasion all horses were tested following i.v. administration of xylazine (0.4 mg/kg) and following i.v. administration of lobeline hydrochloride (l.hy.; 0.2 mg/kg) to evaluate the effect of xylazine and l.hy. on different spirometric variables. Ultrasound-based spirometry proved to be an easily applicable method for lung function testing, even in difficult horses. However, there existed a pronounced physiological variation for all measured lung function parameters and no significant differences between healthy horses and horses with chronic bronchiolitis could be found except for the expiratory tidal volume (VTE p < 0.05). Individually, a marked decrease of variability from breath to breath following either xylazine and l.hy. administration could be observed for all parameters, except the flow-time-ratio (Tpef./ Texp.) and the flow-volume-ratio (Vpef./Vexp).
