Left perinephric abscess associated with nephrolithiasis and bladder calculi in a bitch

An eight-year-old, entire female Pekingese cross, weighing 3.8 kg, had been inappetent with fever, depression, abdominal pain, vomiting and diarrhoea for seven days. The radiographic and ultrasonographic findings were consistent with glomerulonephritis, nephrolithiasis in both kidneys, bladder calculi and an accumulation of fluid in the left perinephric space. The clinical signs, together with the results of the diagnostic imaging, suggested that this fluid could be pus. A definitive diagnosis of a subcapsular abscess in the left kidney was established when this kidney was removed surgically. A histopathological examination of the kidney revealed a diffuse suppurative interstitial nephritis, membranous glomerulonephritis and an abscess invading the perinephric adipose tissue from the renal cortex. Twelve months after surgery the dog remains clinically stable, but owing to the disease of its remaining kidney its long-term prognosis is poor.     

京巴犬产后期大出血的紧急救治1例

通常情况下,母犬产后阴道中排出物略呈绿色是正常的,一星期后逐渐减少,直至消失。但产后期大出血就不同,它发生在母犬分娩后的第8天,突然从阴门口大量流血,若不及时抢救,将危及犬的生命。现将我院救治情况报道如下:一、发病经过余姚赵先生养了8年取名为“小花”的京巴犬,以前的     

Partial foetal retention following aglepristone treatment in a bitch

This short communication describes the case of partial foetal retention in an 18-month-old female French bulldog following induction of abortion owing to an undesired mating. Abortion was induced with aglepristone administered in two consecutive protocols of a dual injection 1 day apart. After failure of the first treatment to achieve abortion, 15 days later, a second treatment was administered. Delivering of aborted foetus occurred 2 days after the last administration. Five weeks after the abortion, the female showed a weak haemorrhagic vaginal discharge. On ultrasound examination, the presence of uterine wall distension as well as a puppy skull inside the uterus was observed. This clinical case makes clear that although aglepristone is a very reliable drug, follow-up of the female during treatment and in the immediate post-partum is necessary to ensure a good outcome.     

Surgical management of bilateral diaphragmatic paralysis in a dog

Bilateral diaphragmatic paralysis of uncertain cause developed in a 3-month-old Golden Retriever. A surgical procedure for tightening the diaphragmatic muscle was used to help alleviate the dog's respiratory distress. During thoracotomy, the central tendon of the diaphragm was plicated, using an interlocking suture pattern. The dog improved after surgery, and although complete recovery from paralysis was achieved only on one side, the dog has remained clinically normal 1 year after surgery.     

Silicate renal calculi in Kenyan dogs

Renal calculi were detected in 124 (53%) of 241 native Kenyan dogs during a necropsy survey for Spirocerca lupi infection. Affected kidneys were grossly normal but histologically pyelitis was present in 33% of the dogs. Over 50% of the stones were bilateral. Most were small and yellowish, the largest one was 2.5 cm. One native dog had a cystic calculus that obstructed its bladder.
Chemical analysis of the calculi revealed only traces of magnesium and phosphate. Emission spectrum studies identified the calculi as magnesium calcium aluminum silicate.
Decreased water intake or increased insensitive water loss do not seem to be important causative factors. Silica levels in water and maize should be determined.     

Ovarian teratoma in a bitch

An ovarian teratoma in a 5-year-old bitch with a history of vaginal discharge was removed successfully by ovariohysterectomy. The mass was discovered on abdominal palpation and contained multiple mineralized densities that were visualized radiographically. Histologic examination of the mass confirmed the presence of tissues originating from multiple germ-cell layers, characteristic of a teratoma. Clinical findings in dogs with teratomas include abdominal distention, a palpable abdominal mass, and rarely, evidence of reproductive hormonal activity. These neoplasms are uncommon in the dog, and they may exhibit malignant tendencies, with metastasis developing in approximately 33% of the reported cases. Ovariohysterectomy is the preferred treatment for ovarian teratomas, and this procedure was curative in the dog of this report.     

Oestrogen-induced alopecia in a bitch

An 8-year-old, spayed female Labrador Retriever, which had been treated with oestrogens for urinary incontinence, developed non-pruritic, bilaterally-symmetrical alopecia and skin hyperpigmentation, with enlargement of mammary glands and vulva. Skin biopsy changes were consistent with an endocrine alopecia, hypothyroidism and hyperadrenocorticism were excluded by hormonal tests. Oestrogen-induced alopecia was suspected and hormonal treatment withdrawn. Two months later, hair regrowth was almost complete and genital changes were lessened.     

Polycythaemia vera in a bitch

Polycythaemia vera was diagnosed in a 5-year-old Labrador Retriever bitch on the basis of an increased red blood cell mass without a decrease in the normal arterial blood oxygen concentration. Treatment with 2 mCi intravenous radioactive phosphorus (³² P ) was followed 5 months later by a reduction in the red blood cell mass which persisted for a further 5 months. Thereafter, the red cell mass increased and the animal died 8 months later. Post-mortem examination showed the presence of generalized vascular congestion, fibrosis affecting the blood vessels, degeneration of parenchy-matous organs and increased haematopoiesis and erythrocyte destruction. Résumé. On a diagnostiqué la polycythémie vera chez une chienne Labrador Retriever, ǎgée de 5 ans, sur base de la proportion accrue de globules rouges sans qu'il n'y ait de baisse de la concentration normale d'oxygène dans le sang artériel. Après le traitement au phosphore radioactif intraveineux 2 mCi (³²P), on a assisté, 5 mois plus tard, à une réduction de la masse des globules rouges, qui s'est maintenue pendant encore 5 mois. Ensuite, la proportion de globules rouges augmenta et l'animal mourut 8 mois après. L'autopsie a révélé une congestion vasculaire généralisée, une fibrose affectant les vaisseaux sanguins, une dégénération des organes paren-chymateux et une destruction accrue de l'hématopoésie et des érythrocytes. Zusammenfassung. Polycythaemia vera wurde bei einer 5 Jahre alten Labrador-Retriever. Hündin auf Grund einer erhöhten Erythrocytenmasse ohne Verminderung der normalen arteriellen Blutsauerstoffkonzentration diagnostiziert. Auf die Behandlung mit 2 mCi intravenös verabreichten radioaktiven Phosphors (³²P) folgte nach 5 Monaten eine Verminderung der Erythrocytenmasse, die weitere 5 Monate anhielt. Danach stieg die Erythrocytenmasse wieder an und das Tier starb 8 Monate später. Die Autopsie ergab das Vorhandensein einer generalisierten arteriellen Kongestion, Fibrosis der Blutgefässe, Degeneration der parenchymatösen Organe und vermehrte Hämatopoese und Erythrocytenzerstörung.     

Ovarian dysgerminoma in a bitch

A nine year old Terrier-Chihuahua crossbred bitch was presented to the Western College of Veterinary Medicine with a history of anorexia, vomiting and diarrhea. A palpably enlarged uterus and purulent vaginal discharge were found on physical examination. Pyometra was diagnosed and ovariohysterectomy was subsequently performed. One ovary was twice the size of the other, firm and mottled grey-white on the cut surface. A dysgerminoma involving the larger ovary was diagnosed on histological examination. This tumor, closely resembling the male seminoma, was characterized by a uniform population of large round cells with scant acidophilic cytoplasm, frequent mitotic figures and focal aggregates of lymphocytes. History and clinical signs were considered to relate to the pyometra rather than the dysgerminoma. No conclusions could be made regarding hormonal elaboration by the tumor because sex hormone levels were not measured. Two years following discharge the dog was reported to be well.
