Examination of the urine sediment is part of a routine urinalysis and is undertaken in order to identify insoluble particles in the urine. This procedure is mainly used in the context of diagnostic evaluation of urinary tract diseases, but may also be useful for the diagnosis of systemic diseases and intoxications. Analysis of fresh urine is recommended as changes in cell morphology, cell lysis and in vitro crystal formation may occur in the course of its storage. Manual urine sediment analysis is still performed in many veterinary practices. Native wet-mount preparations are suitable for the identification and quantification of urine sediment particles. The examination of stained wet-mount preparations or air-dried smears may be necessary to further differentiate cells and to identify bacteria. For several years, automatic urine sediment analyzers have been available in veterinary medicine. These save considerable time and staff resources, however verification of the automatically generated results by an experienced observer remains necessary. Urine sediment particles that are frequently identified and clinically relevant include red blood cells, white blood cells, different types of epithelial cells, crystals, and casts as well as bacteria. Furthermore, parasite eggs, fungal hyphae, lipid droplets, spermatozoa, fibres, hair, mucus, plant parts or environmental contaminations may be found in the urine sediment and result in a complication of the result interpretation.

A 50-year-old female Hermann's tortoise (Testudo hermannii boettgeri) was presented with anorexia and lethargy. Clinical examination revealed multiple, visually inconspicuous but indentable areas in the shell corresponding to osteolysis radiographically. Soft tissue nodules and osteolytic lesions were also noted in the limbs. Laboratory results revealed elevated aspartate aminotransferase activity and uric acid concentrations, hypoglycemia, and hyperphosphatemia. Klebsiella oxytoca was isolated from a biopsied scutal area, and the biopsy suggested neoplasia. After a short period of clinical improvement, the animal's condition deteriorated, and it died. Post mortem computed tomography revealed polyostotic lytic lesions of multiple bones and the shell with associated soft tissue nodules protruding into the coelom, and nodular lung lesions. Necropsy, histopathology, and immunohistochemistry secured a diagnosis of a poorly differentiated, pan-cytokeratin-positive squamous cell carcinoma with widespread soft tissue and bone metastases, osteolysis and desmoplasia.

Feline infectious peritonitis (FIP) is one of the most common infectious diseases in cats that is fatal when untreated. So far, there is no legally available effective treatment in Germany. Treatment options include only symptomatic treatment (e. g. glucocorticoids, propentofylline), immunomodulatory approaches (e. g. interferons, polyprenyl immunostimulant), and antiviral chemotherapy with protease inhibitors (e. g. GC376) or nucleoside analogues (e. g. GS-441524, remdesivir). Symptomatic treatment does not cure FIP but may lead to a short-term improvement of clinical signs in a subset of cats. Immunomodulatory treatment has also not shown to be very promising. In contrary, the antiviral compounds GS-441524 and GC376 exhibited significant efficacy in several studies and their use saved the lives of many cats suffering from FIP. However, both agents are currently not licensed and thus cannot be legally administered by veterinarians in Germany. Legally, cats may only be legally treated with GS-441524 in a few countries (e.g. Great Britain and Australia). In other countries, GS-441524 is imported by cat owners via the black market and administered on their own. This article provides an overview of the available treatment options and an outlook on the legal use of effective antiviral drugs.

A 4-year-old, spayed female mixed breed dog was presented with large crater-like, well-demarcated, erosive and ulcerative necrotic lesions of the skin, elevated body temperature and lethargy, that began 14 days after vaccination and treatment with fluralaner and milbemycin/praziquantel. Cytology revealed severe pyogranulomatous inflammation with moderate numbers of extracellular microorganisms. Histopathologic examination showed severe multifocal pyogranulomatous dermatitis and panniculitis with severe dermal edema and severe neutrophilic exocytosis with band-like infiltration of the lower portion of the epidermis consistent with pyoderma gangrenosum. Despite intensive immunosuppressive and antimicrobial therapy and intensive inpatient care, the dog was euthanized 16 days after admission due to complications with clinical signs of sepsis, acute dyspnea and thoracic effusion.

The anti-Mullerian hormone is a glycoprotein secreted by Sertoli cells in males and granulosa cells in females. The initial identification of this hormone in canine and feline serum was achieved in 2011. Meanwhile, a variety of studies have demonstrated its clinical significance as a tool in the endocrine diagnosis. This review summarizes the current knowledge about anti-Mullerian hormone in small animal reproduction and describes future opportunities for its diagnostic usage.

Objective: Innovative teaching strategies such as case-based learning and hands-on training are more and more integrated into undergraduate veterinary teaching. Nevertheless, it can be assumed that lectures still play an important role in many vet schools. Nowadays, however, lectures are questioned to be motivating and engaging enough for a long-lasting learning retention. In this context, we compared acceptance and learning outcome of the teaching methods reading, writing, and listening to a presentation.

Material and methods: In structured settings based on a cross-over design, 151 students in their fifth year attending a 2-weeks clinical rotation at the Clinic for Animal Reproduction were asked to read papers, listen to a presentation by a lecturer, and to write a summary in group work. Each task dealt with 1 of 3 topics from the field of animal reproduction. A week later, the students were asked to complete a multiple-choice test and an evaluation form. The test contained questions about each of the covered topics as well as a fourth topic, which was not taught in context of this project to assess the students' prior knowledge.

Results: The results revealed that writing a summary in group work led to the best learning outcome, but it cannot be ruled out that learning success may have depended to a large extent on group work. Furthermore, the results did not differ significantly from the second-best teaching method listening to a presentation. The teaching method students preferred most was the lecture, followed by reading papers and writing a summary.

Conclusions: We conclude that presentations by lecturers are still an important teaching method but can be complemented by writing tasks, which may be used in specific settings as a possible way to improve learning outcome in veterinary education.

Conclusion for practice: Our project supports the assumption that more active, student-centered learning approaches such as writing summaries can lead to more engagement and a better learning retention. In addition, training writing skills is important because clinical reports and other written communication are relevant parts of daily veterinary routine.

This case report describes the occurrence of canine herpesvirus 1 in a litter of French bulldogs. In addition, the literature dealing with CHV-1 in puppies is summarized. Two puppies were presented due to dyspnea. During the night, one of them developed diarrhea as well as a highly disturbed general condition and was subsequently euthanized the following day. The second puppy was euthanized 6 hours later with a highly disturbed general condition. Necropsy revealed evidence of canine herpesvirus infection. This was confirmed by a virological examination. The presented case report shows that canine herpesvirus infection must also be considered as a cause of death in newborn puppies in Germany.

Diagnostic imaging represents an important part during modern pregnancy management of the dog. Ultrasound has become the modality of choice for an early pregnancy diagnosis, enabling a verification as early as 17-20 days after LH surge. Furthermore an evaluation of fetal viability and development is possible as well as the depiction of malformations and an early assessment of fetal stress. Doppler imaging may also be of supporting value in this context . Using fetal maturity as well as measurements of fetal and extrafetal structures, a calculation of the gestational age and therefore the time of parturition is achievable. Radiographs of the caudal abdomen enable pregnancy diagnosis from the 43^rd day after LH surge onward. In addition, an assessment of fetal size as well as litter size is possible. Both modalities allow for complementary statements concerning possible labor complications and possess supporting value concerning the decision of necessary obstetric intervention and further management in patients with dystocia.
