Abstract
Summary
ObjectivePathologic gastroesophageal reflux (GER) has been demonstrated experimentally in dogs, and it is suspected to occur naturally in dogs, yet its clinical significance is unknown. The aim of the study was to demonstrate clinical indicators of pathologic GER in dogs with idiopathic esophagopathies. Materials and methods: Dogs with clinical signs suggestive for esophageal disease (regurgitation, ptyalism, or dysphagia) and where extraesophageal and specific esophageal diseases had been ruled out, were retrospectively diagnosed with idiopathic esophagopathies. History, physical examination findings, clinicopathologic, radiographic, and endoscopic data, and treatment results were obtained from medical records, reviewed and evaluated. Results: Out of 67 dogs with anamnestic esophageal signs, 12 (17.4%) dogs were identified as having idiopathic esophagopathies and were included in the study. Median age was 3.0 years (range 1.0–11.0), and median bodyweight was 28.2 kg (range 8.2–44.0). The most frequent anamnestic esophageal signs were ptyalism (10/12 dogs), regurgitation (8/12 dogs), signs of discomfort, pain (8/12 dogs), and cough (5/12 dogs). The most common radiographic abnormality was segmental esophageal dilation (8/12 dogs). Esophagoscopy revealed single mucosal surface defects at the gastroesophageal junction in 3/12 dogs. In dogs with altered esophageal motility, cytological and microbiological examinations of bronchial aspirates showed goblet cell hyperplasia (8/8 dogs), neutrophilic infiltration (5/8 dogs) and culturable bacteria (4/8 dogs), respectively. All dogs were treated with omeprazole (median 0.7 mg/kg once per day, range 0.5-1.2). Reported median treatment duration until remission of the main clinical signs was 20.0 days (range 8.0–54.0 days). This endpoint was reached in 11/12 dogs. Conclusion and clinical relevance: Results suggest that in some dogs with esophageal clinical signs, and where no primary disease could be identified, clinical indicators of pathologic GER such as pain, mucosal lesions and motility disturbances of the esophagus, respiratory complications, and response to therapy can be observed.

Abstract
ZusammenfassungEine 3-jährige Alpakastute wurde wegen Tenesmus in die Klinik eingeliefert. Bei der klinischen Untersuchung konnte ein habitueller Vaginalprolaps mit Tenesmus während des Harn- und Kotabsatzes beobachtet werden. Vaginoskopisch zeigte sich ein persistierendes Hymen. Bei der sonographischen Untersuchung des Abdomens stellte sich im kaudalen Abdomen ein mit echogener Flüssigkeit gefüllter Uterus dar. Die Probelaparotomie ergab die Diagnose Pyometra. Nach der durchgeführten Ovariohysterektomie kam es zur komplikationslosen Rekonvaleszenz. Eineinhalb Jahre später wurde das Alpaka wegen Kolik erneut vorgestellt. Aufgrund der erhobenen Befunde bestand eine vorsichtige Prognose ad vitam, weshalb die Stute auf Wunsch der Besitzer euthanasiert wurde. Bei der Sektion zeigte sich eine hämorrhagische Infarzierung einer Jejeunumschlinge, die durch eine bindegewebige Verwachsung zwischen Vaginalstumpf und Jejunumschlingen inkarzeriert war.

Abstract
We present the clinical findings, diagnosis and treatment of an 11-year old intact male Fox Terrier with a malignant Leydig cell tumor of the right testicle, which metastasized to the skeletal musculature of the left hind limb. The primary tumor and the metastasis were resected with narrow margins. The dog was treated with metronomic chemotherapy using thalidomid and dyclophosphamide. Local recurrence at the site of the metastasis and a pulmonary metastasis were present 30 months after surgery. The dog was euthanized.

Abstract
A 3-year-old female alpaca was referred to the hospital because of tenesmus. Clinical examination revealed a habitual vaginal prolapse with tenesmus during urination and defecation. On vaginoscopic examination a persistent hymen was detected. Ultrasonography of the caudal abdomen showed an echogenic fluid-filled uterus. A diagnostic laparotomy led to diagnosis of pyometra. Following ovariohysterectomy, the recovery was uneventful. One and a half years later the alpaca was again admitted to the hospital because of colic. Based on the findings, a tentative prognosis was provided and the alpaca was euthanized at the request of the owner. At necropsy, a haemorrhagic infarction of a jejunal loop was found due to incarceration in a fibrous adhesion between the vaginal stump and small intestine.

Abstract
A 10-year-old Swiss Braunvieh cow near term was referred to our clinic because of severe abdominal distension, which caused loss of demarcation between the udder and ventral abdominal wall. Ultrasonographic examination revealed marked ascites and multiple echogenic nodules in the greater omentum. Based on the findings, non-inflammatory ascites attributable to neoplasia was diagnosed. Rupture of the prepubic tendon from the pubic symphysis was also suspected. Because of a grave prognosis, parturition was induced and a live calf was delivered. The cow was euthanized and a postmortem examination was carried out. The abdominal cavity contained 248.5 litres of clear fluid. The greater omentum was thickened and oedematous and regionally contained fluid-filled cystic structures, which varied in size with a maximum diameter of 10 centimetres. Based on the histological, immunohistochemical and electron microscopical findings, biphasic mesothelioma with cyst formation affecting the entire abdominal cavity was diagnosed.

Abstract
This report describes an 8.8-year-old Simmental cow with squamous cell carcinoma of the reticulum and liver. The cow had calved recently and was referred to our clinic because of intractable fever, anorexia and progressive indigestion. The general condition and mental status were moderately affected and rectal temperature and respiratory rate were significantly elevated. There were no ruminal sounds and pinching of the withers consistently elicited a grunt. Serum activities of gamma glutamyl transferase, glutamate dehydrogenase and sorbitol dehydrogenase were elevated. Radiographic examination of the reticulum and ultrasonographic examination of the reticulum, liver and abdominal cavity revealed multifocal, poorly demarcated, heterogeneous and echogenic changes in the liver. Biopsy of these lesions yielded a diagnosis of squamous cell carcinoma. The cow was euthanized and a postmortem examination confirmed the diagnosis. A 15 by 15 cm neoplasm was found in the reticular wall, and histological examination showed squamous cell carcinoma. It was assumed that the reticular mass was the primary tumour, which metastasized to the liver via the portal vein.

Abstract
A six-year-old Rottweiler with chronic ascites and moderate panhypoproteinaemia that had been treated with large volume paracentesis over several months duration was diagnosed with a large bi-atrial mass and hepatic fibrosis. For palliative treatment, a peritoneo-vesical automated fluid shunt system with an integrated chargeable battery and an integrated computer to control pump function and to transmit data transcutaneously was implanted by coeliotomy. The pump was left in place for 10 weeks, eliminating the need for further paracentesis during this time. At the end of this period, no ascites was discernible and serum protein concentrations had returned to their respective reference intervals. As a complication, decubitus with skin perforation had developed above the pump. Besides palliative treatment of chronic refractory ascites, this pump may have application in other conditions characterised by chronic cavity effusion or in peritoneal dialysis.

Abstract
This case report describes a three-year-old Friesian stallion with hypospadias. Physical examination revealed a ventrocaudal deviation of the shaft of the penis and an incomplete glans penis. The urethral opening was 4 cm in length, slit-like and had a mucous membrane covering. A short fold ran from the ventral aspect of the anus and ended with a non-pigmented hairless area of skin. A human choriongonadotropin (hCG)-stimulation test resulted in an increase in the plasma levels of estrogen sulfate and testosterone, indistinguishable from that of a normal stallion. The karyogram had a normal number of chromosomes at 2n=64. The stallion was castrated, and histological evaluation of the testicular tissue was unremarkable. In contrast to other animal species and human beings, hypospadias is a rare congenital abnormality in stallions, the cause of which could not be elucidated in our patient.

Abstract
Listeria monocytogenes infection, although rare in horses, can lead to septicaemia, gastroenteritis and abortion or stillborn foals. Equine cerebral listeriosis has been reported, but only in newborn animals. This report describes a Freiberger gelding with severe neuronal symptoms of sudden onset. The animal collapsed within 24 h and was humanely killed. Necropsy revealed multiple small brown to reddish foci within the brain stem and pons. Histopathology demonstrated multifocal suppurative meningoencephalitis with microabscesses and occasional intra-lesional, coccoid to rod-shaped, bacteria. These were identified immunohistochemically as Listeria spp. and further specified as L. monocytogenes by a commercial test system based on in-situ hybridization.

Abstract
Fashionable clothing involving tight-fitting trousers and high heels forces human to adopt an attitude leading to diseases at the point of insertion of the tendons and of the cartilage of the patella. It is emphasized that malformations of the femoropatellar joint may possibly be caused by exogenous influences and may, therefore, be successfully treated by externally applied methods during the growth period.
