[Digitization in Swiss veterinary practices]

INTRODUCTION

Data on the digitization in Swiss veterinary practices and clinics were collected in a survey from June 2017 to the end of December 2017. Data of 171 practices contributed to the survey. Animal records were filed in 96.5% with a practice management program. Nine out of ten practices operate an x-ray machine whereof 70% digitally record the radiographs. While a moderate diversity of practice management systems is used, numerous different radiographic recording, archiving and viewing systems are utilized. Data exchange with other practices and owners preferably takes place via e-mail, followed by upload servers and digital data carriers. Data protection receives less attention in veterinary medicine than in comparison to human medicine. A protected data exchange platform coupled with AMICUS and ANIS is under construction via standardized DICOM (https://www.dicomstandard.org/current/) and HL7 (https://www.hl7.org/) interfaces.

[AntibioticScout.ch: A decision supporting tool for antimicrobial stewardship: application to companion animal medicine]

INTRODUCTION

Bacterial resistances to antimicrobial drugs pose serious public health challenges. The observed increase of resistances is attributed to the uncontrolled, massive and often unnecessary administration of antibiotics both in human and veterinary medicine. To support the responsible use of antimicrobials in animals and help veterinarians selecting the most suitable antimicrobial drugs, we developed the AntibioticScout.ch as a comprehensive decision supporting tool providing online access to the current knowledge of rational antibiotic prescription practices. User-friendly search functions allow for the fast and efficient retrieval of information that is structured in this database by animal species, organ systems and therapeutic indications. In addition, an online form allows to report treatment failures in order to identify problematic cases as well as ensuing risks and take appropriate mitigation measures. The present report describes the workflow of this decision support system applied to the prudent use of antimicrobials in companion animal medicine.

A prospective study on canine atopic dermatitis and food-induced allergic dermatitis in Switzerland

Canine atopic dermatitis sensu stricto and food-induced allergic dermatitis are common canine skin conditions, which are often considered clinically undistinguishable. Several attempts have been made to describe populations of atopic dogs and determine breed predisposition but the results were often biased by the use of hospital populations as control group. The present study aims to describe a population of Swiss atopic and food-allergic dogs and to compare it with a data set representing more than 85% of all Swiss dogs. The study, which was carried out during 1 year in several practices and teaching hospital in Switzerland, describes a group of 259 allergic dogs, determines breed predisposition for atopic dermatitis and food-induced allergic dermatitis, compares the clinical signs and features of both conditions, and outlines the clinical picture of five frequently affected breeds.

Keine synergistische Wirkung der Kombination von ∆9-Tetrahydrocannabinol und Piritramid bei postoperativen Schmerzen

BACKGROUND

It is concluded from animal experiments that cannabinoid receptor and mu-opioid receptor agonists act synergistically with respect to antinociception. In order to demonstrate this effect under clinical conditions, we conducted a randomized double blind trial with patients after radical prostatectomy.

PATIENTS AND METHODS

From the evening before the operation until the morning of the second postoperative day, all patients received eight oral doses of either placebo or 5 mg Delta(9)-tetrahydrocannabinol (dronabinol). Postoperatively patients had access to patient-controlled analgesia with the micro-opioid agonist piritramide for 48 h. We expected patients receiving dronabinol to require significantly less piritramide compared to patients on placebo.

RESULTS

The consumption of piritramide was recorded in 100 patients after radical retropubic prostatectomy with regional lymphadenectomy. Patients in the placebo group consumed 74 mg (median), interquartile range (IQR) 44-90 mg, patients in the verum group consumed 54 mg (median) IQR 46-88 mg. The difference between groups was not statistically significant. Plasma concentrations of Delta(9)-THC were measurable in all patients in the verum group. The levels (median) were 1.5 ng/ml (IQR 0.6-2.3), 1.3 ng/ml (IQR 0.5-2.2) and 1.9 ng/ml (IQR 0.8-2.7) on the day of operation, the first and second postoperative day, respectively.

CONCLUSION

We found neither a synergistic nor even an additive antinociceptive interaction between Delta(9)-tetrahydrocannabinol and the micro-opioid agonist piritramide in a setting of acute postoperative pain.

Ultrasonography of the parathyroid glands as an aid in differentiation of acute and chronic renal failure in dogs

OBJECTIVE

To evaluate whether determination of parathyroid gland size by use of ultrasonography is helpful in differentiating acute renal failure (ARF) from chronic renal failure (CRF) in dogs.

DESIGN

Prospective study.

ANIMALS

20 dogs with renal failure in which serum creatinine concentration was at least 5 times the upper reference limit. Seven dogs had ARF, and 13 dogs had CRF. Twenty-three healthy dogs were used as controls.

PROCEDURE

Dogs were positioned in dorsal recumbency for ultrasonographic examination of the ventral portion of the neck, A 10-MHz linear-array high-resolution transducer was used. The size of the parathyroid gland was determined by measuring the maximal length of the gland on the screen when it was imaged in longitudinal section. For comparison among groups, the longest linear dimension of any of the parathyroid glands of each dog was used.

RESULTS

Size of the parathyroid glands in the control dogs varied from 2.0 to 4.6 mm (median, 3.3 mm). In the dogs with ARF, gland size ranged from 2.4 to 4.0 mm (median, 2.7), which was not significantly different from controls. In dogs with CRF, the glands were more distinctly demarcated from the surrounding thyroid tissue, than those of controls and dogs with ARF. Sizes ranged from 3.9 to 8.1 mm (median, 5.7 mm), which was significantly larger, compared with controls and dogs with ARF.

CONCLUSIONS AND CLINICAL RELEVANCE

In dogs with severe azotemia, ultrasonographic examination of the parathyroid glands was helpful in differentiating ARF from CRF Size of the parathyroid glands appeared to be related to body weight.
