Omentalisation of perinephric pseudocysts in a cat.

An 11-year-old male domestic shorthaired cat was presented with behavioural disturbances and abdominal distension of two days' duration. Haemobartonella felis was found on routine haematology and serum biochemistry showed mild azotaemia. Abdominocentesis revealed a transudate. Bilateral perinephric fluid accumulations were observed on ultrasonography and chronic nephrosclerosis was diagnosed on needle biopsies of the kidney. A celiotomy with resection of the major portion of both cyst walls was performed. The omentum was extended along the floor of the abdomen, across the ventral aspect of both kidneys and attached to the remnants of the pseudocyst wall. Ongoing physiological drainage was secured and cyst recurrence was prevented. Perirenal fluid was not detected at clinical and ultrasound follow-up examinations 14 days and seven months postoperatively. Mild azotaemia and refractory Haemobartonella infection were, however, still present.

Vulvovaginectomy and neo-urethrostomy for treatment of haemangiosarcoma of the vulva and vagina.

Vulvovaginectomy and neo-urethrostomy were performed in a 9-year-old German shepherd dog following a diagnosis of infiltrative vulvar and vestibulovaginal haemangiosarcoma. The dog was presented for intermittent vulvar haemorrhage over a 3-month period. On examination the vulva and vestibulovagina were distended and firm. Vaginal discharge and fine needle aspiration cytology detected anaplastic cells. Haemangiosarcoma was diagnosed on biopsy. A new urethral opening was created in the floor of the vagina allowing resection of the vulva and caudal vestibulovagina. Urinary continence was preserved and healing was without complications.

Health care: a social contract in transition.

Health care reform around the world is born in considerable measure of the need to reconcile our growing capacity to provide effective health care with diminishing economic means to sustain this capacity indefinitely. It is precisely under these circumstances that the conflict between individual rights to health care and the state's responsibilities to provide it becomes unavoidable. Although it cannot be eliminated, the conflict can be managed. But the task requires us to go beyond formulating economic policies or designing new structural systems for delivering health care. It requires an understanding of the purpose of health care for individuals and society. It includes stipulating limitations for individual rights and state responsibilities. Because of these limitations, the task must be guided by the requirements of justice. Health care as both a private and common good is at the center of a distributive struggle. At one level the focus of this struggle is economic and political. At another level it is moral and revolves around the concept of health itself, considered in its biological, psychological and social dimensions. Here the issue becomes health as a right, together with the implications such a right has for our efforts to balance the freedom of individual health-related behavior with the interests of the public's health. What, in that balance, are the rights of the individual and the responsibilities of the state? Can the individual citizen hold the state accountable for securing the conditions necessary for health? Can the state hold its citizens accountable for irresponsible health-related behavior? A discussion of providing liver transplantation sheds considerable light on these questions, while suggesting a paradigm for use with general health care services. Central to this paradigm is the welfare concept of right, balanced by the understanding that a citizen's claim on health care services is limited. In the final analysis, justice in health care will be achieved through a division of labor, at the center of which there is a set of reasonable and binding expectations shared reciprocally between the individual and the state.

The cultural and philosophical foundations of normative medical ethics.

Thirty years ago, the idea that culture and philosophy could provide a foundation for normative medical ethics was more easily entertained than it is today when the very notion of a norm, whether culturally, philosophically or ethically derived, is in itself a problem. In large measure this comes from our contemporary embrace of cultural and philosophical pluralism and an increasing tendency to exchange the difficult belief in abstract and universally applicable norms for the more accessible notion that ethical values are cultural and relative derivatives. Despite this, in the face of the unprecedented ethical dilemmas presented by modern medicine, we have attempted to apply traditional ethical norms and analysis to modern medicine to establish a consensus for its right practice. Unfortunately, the attempt has not been successful, so that wherever we turn we find that ethical problems in medicine remain intractable and unresolved. That, in turn, has prompted a certain scepticism about the efficacy of ethics in medicine. In order to understand why we have reached this impasse, it is essential to realize that we have seriously underestimated the way science and technology have informed and, as a consequence, transformed the practice of medicine. Contributing to this, our tendency to think of technology simply as a way of doing things has blinded us to the fact that it is more fundamentally a way of thinking, knowing and valuing.(ABSTRACT TRUNCATED AT 250 WORDS)

Sartorius muscle contracture in a dog.

An adult male German Shepherd dog presented with a chronic non-painful, non-weight bearing lameness of the right hind limb. On clinical examination a contracted sarotorius muscle was palpable. Histopathology of the affected muscle confirmed replacement fibrosis and muscle contracture. Surgical excision of the muscle resulted in complete recovery.

Coccidia (Apicomplexa: Eimeriidae) from sciurid rodents (Eutamias, Sciurus, Tamiasciurus spp.) from the western United States and northern Mexico with description of two new species.

Since May 1979, 190 rodents in the family Sciuridae, representing three genera and nine species, have been collected in the western United States and northern Mexico and examined for coccidia; 71 (37%) had coccidian oocysts in their feces. These included 2 of 12 (17%) Eutamias canipes; 7 of 12 (58%) E. dorsalis; 18 of 50 (36%) E. merriami; 33 of 96 (34%) E. obscurus; 3 of 4 (75%) E. townsendii; 3 of 9 (33%) Sciurus aberti; 1 of 1 S. griseus; 1 of 1 Tamiasciurus hudsonicus mogollonensis; and 3 of 5 (60%) T. mearnsi. The following coccidians were identified from infected rodents: Eimeria cochisensis n. sp. and Eimeria dorsalis n. sp. from E. canipes, E. cochisensis, E. dorsalis, and E. tamiasciuri from E. dorsalis, E. dorsalis and E. tamiasciuri from E. merriami; E. cochisensis, E. dorsalis, E. tamiasciuri, and E. wisconsinensis from E. obscurus; E. cochisensis and E. dorsalis from E. townsendii; E. ontarioensis and E. tamiasciuri from S. aberti; E. tamiasciuri from S. griseus; E. tamiasciuri and E. toddi from T. h. mogollonensis; and E. tamiasciuri from T. mearnsi. Sporulated oocysts of Eimeria dorsalis n. sp. were ovoid, 21.9 x 16.8 (17-24 x 14-20) micrometer with sporocysts ovoid, 11.5 x 6.9 (10-14 x 6-8) micrometer. Sporulated oocysts of Eimeria cochisensis n. sp. were spheroid to subspheroid, 16.7 x 15.3 (15-18 x 14-17) micrometer, with sporocysts ovoid, 8.4 x 5.6 (6-11 x 4-7) micrometer. Fifty-five of 71 (77%) infected hosts had oocysts of only one eimerian species in their feces at the time they were examined. One eimerian, E. tamiasciuri, was found in seven of nine host species in three genera. A list is provided of all eimerians (22, including the species described here) that have been described in the literature from Eutamias, Sciurus, and Tamiasciurus spp.
