The use of a split eyelid flap to reconstruct both a normal palpebral aperture and a smooth, hairless eyelid margin following the excision of eyelid neoplasia, in a series of seven dogs, is described. The patterns of reconstruction used in the procedure are discussed, and previously reported methods of eyelid reconstruction are reviewed. 相似文献

Eyelid surgery plays an important role in the management of a variety of ophthalmic diseases. Surgery on the adnexa and eye is routinely performed on an anesthetized patient. Minor procedures, such as conjunctival biopsy, may be performed in an awake patient using only topical anesthesia. Retrobulbar, peribulbar, and local anesthesia are less commonly used in general practice; however, they can provide significant advantages when used appropriately. Advantages to local anesthesia/sedation include being able to perform some ophthalmic procedures without having to place the patient under general anesthesia, ability to maintain the patient under a lighter plane of general anesthesia, improved postoperative comfort, and potentially smoother recoveries from general anesthesia. This article reviews this author's current indications and techniques for regional anesthesia as an adjunct to eyelid surgery in dogs. 相似文献

There is a need to develop simple, rapid, and accurate methods for assessing health in fish populations. In this study we demonstrate that use of fluorescein, a nontoxic fluorescent dye, can rapidly and easily detect the presence of skin ulcers in all fish tested, including rainbow trout (Oncorhynchus mykiss), channel catfish (Ictalurus punctatus), goldfish (Carassius auratus), and hybrid striped bass (Morone saxatilis male X M. chrysops female). Exposure of fish to as little as 0.10 mg fluorescein per milliliter of water for 3 minutes was sufficient to identify experimentally induced lesions, even pinpoint ulcerations. Such lesions were not visible to the naked eye but were clearly demarcated with fluorescein treatment. Examination of fish that appeared clinically normal often revealed the presence of focal ulcerations, which might have been a consequence of damage during capture, but it also might suggest that skin ulceration may be common even in "clinically normal" fish. Exposure of either nonulcerated or experimentally ulcerated hybrid striped bass to an excessively high concentration of fluorescein had no apparent effect on health or survival. Our studies suggest that fluorescein may be a highly useful tool for rapid health screening in fish populations. 相似文献

This case report documents the use in a cat of a method of palpebral reconstruction previously only described in a series of dogs. A split eyelid flap was used to reconstruct a deficit created by the removal of an apocrine adenoma of the paratrichial sweat gland on the upper lid. This particular technique was chosen over other methods because of its ability to create a smooth hairless eyelid margin. The method previously described in dogs was modified in the present case to address both the fact that the resection was more extensive and the difference in periocular anatomy in the cat. 相似文献

A 3-year-old Standardbred gelding was referred for evaluation of a fluctuant swelling that developed over the dorsum of the carpus subsequent to arthroscopic surgery on that carpus. A synovial hernia was diagnosed and surgically repaired. Although complications secondary to arthroscopy are rare, synovial herniation can develop after arthroscopic surgery. The condition must be differentiated from the more common true bursitis or false bursitis that is commonly referred to as a hygroma. 相似文献

OBJECTIVE: To describe an extended pedicle flap based on the superficial cervical artery (SCA) for closure of oral defects in dogs. STUDY DESIGN: Anatomic study; in vivo experimental study. ANIMALS: Canine cadavers (13) and 3 dogs. METHODS: The prescapular branch of the SCA was cannulated and perfused with a lead oxide gelatin mixture. The area perfused by 1 SCA was examined as was the rostral extent of the flap. Staged implantation was performed to evaluate flap performance in vivo. In stage 1, the flap was prepared for implantation into the oral cavity. In stage 2, the flap was fully developed to include the 1 degrees, 2 degrees, and partial 3 degrees angiosome of 1 SCA pedicle. The flap was transposed by a bridging incision and a parapharyngeal tunnel into the oral cavity. The flap was used to reconstruct a partial-thickness defect created in the palate. RESULTS: The territory of the contralateral SCA was captured in all cadavers. The full flap reached the level of the canine teeth in all cadavers. In live dogs, necrosis was not observed after implantation into partial-thickness defects and dehiscence was minimal. Loss of pliability secondary to de-epithelialization and staging resulted in a limitation of rostral reach of the flap. CONCLUSIONS: Whereas the flaps did not reach as far rostrally as anticipated, they survived well in the harsh oral environment. The flap may be modified to reconstruct full-thickness palatal defects. CLINICAL RELEVANCE: The extended SCA pattern flap may be adapted for closure of oral defects. 相似文献

A reliable antemortem diagnostic method is needed for determining infection with canine distemper virus (CDV). The utility of immunohistochemical detection of CDV antigen was examined was examined for samples of nasal and footpad epithelium and haired skin in dogs with and without detectable CDV antigen in the lung and/or brain. Tissues from 57 dogs at risk of CDV infection were tested. Viral antigen was found in the lung and/or brain of 28 dogs. Among these dogs, viral antigen was demonstrated in the epithelial cells of the nasal mucosa in 24 of 27 dogs, in the footpad epithelium in 24 of 26 dogs, and in the haired skin of the dorsal neck in 26 of 27 dogs. Among the 29 dogs without CDV antigen in either the lung or brain, 1 dog had positive staining for viral antigen in the skin and nasal mucosa. Biopsies of haired skin of the dorsal neck, which is relatively simple to sample, can be used for immunohistochemical testing for acute and subacute infection with CDV. 相似文献

Skin test antigens for the diagnosis of brucellosis were produced from the rough Brucella abortus strain 45/20. The production of two products termed Brucellin B and Brucellin W are described. The method described for the production of Brucellin W is recommended as an improved practical method of Brucellin production. The Brucellin products described were equal in sensitivity to that of a commercially available product, Brucellergen, which is used in New Zealand. Brucellin B was extensively tested in non-infected cattle and its specificity was equal to that of Brucellergen. Recommendations for the standardisation of skin test reagents for the diagnosis of brucellosis are made. Intradermal testing for brucellosis in cattle should be used only for the identification of infected herds and not as an individual animal test. 相似文献

In vitro production of embryos, including in vitro maturation, fertilization of oocytes and their subsequent culture to the embryo stage, has become the most popular method of studying gametogenesis and embryogenesis in pigs. As well as their utility for basic studies, these procedures now enable us to generate viable embryos and offspring as a means of conserving genetic resources and rare animal breeds. Recently, more advanced technologies such as xenografting of gonadal (testicular and ovarian) tissues into immunodeficient experimental animals have been developed. In combination with in vitro embryo production techniques, this approach may provide many benefits. We have been carrying out studies to acquire basic information about the application of this method to porcine species, and to improve the existing techniques. Recently, we obtained oocytes from ovarian tissue xenografted and grown in nude mice that had the capacity to be fertilized and the ability to develop into early‐stage embryos. We also obtained spermatozoa from the xenografted testicular tissues and injected them intracytoplasmically into in vitro‐matured oocytes to produce piglets. Here we discuss the further possibilities of conservation and utilization of porcine gonadal tissue by xenografting into immunodeficient mice. 相似文献
