Compression anastomotic healing was associated with less foreign body reactions, scarring, and inflammation as compared with stapled anastomoses in a large animal model.
A captive female square-lipped rhinoceros born in 1993 had been showing intermittent signs of bilateral conjunctivitis and conjunctival proliferation since 1998. Periodic improvement was noted, especially in winter, but overall the condition had deteriorated over the years. Treatment with various topical, intralesional, and systemic antibiotics and glucocorticosteroids was largely ineffective, as were repeated dewormings. No primary cause for these lesions was found in biopsies taken in 2000 and 2006, although a severe infiltrate of numerous eosinophils was observed in the latter. As the condition worsened, secondary corneal changes were noted, and eventually vision was lost due to proliferative conjunctival tissue. Aggressive resection of the proliferating tissue in 2013 restored vision and submitted biopsies yielded a diagnosis of severe allergic conjunctivitis, eosinophilic granuloma, and habronematid (Habronema or Draschia) larval infection. As no other rhinoceros in the herd was affected, including two calves born to the patient who were in close contact with their mother, it was concluded the presentation was most likely due to a hypersensitivity reaction to the dead or dying larvae. Fly repellent is now regularly applied around the eye of this rhinoceros, and a protective face mask has been fitted. Ongoing periodic relapses are treated with oral ivermectin, topical antibiotics, and steroids.
Granulomatous sebaceous adenitis (GSA) is uncommon in dogs; however, certain breed predilections exist. In this report, three cases of GSA in unrelated vizslas have been described. All cases initially presented with episodes of otitis externa followed by severe inner pinnal lesions. In one case, multifocal coalescing inner pinnal ulceration appeared 4 wk prior to the occurrence of the skin lesions. The other two cases presented with simultaneous pinnal and skin lesions following episodes of bilateral otitis. The pinnae were diffusely erythematous and had multiple coalescing erosions and ulcers. The body lesions consisted of multifocal alopecia, papules, and fine scales. Biopsies of the skin and pinnae confirmed GSA. Two dogs responded to treatment with synthetic retinoids and cyclosporin A, respectively. One dog was not treated, and the owners preferred euthanasia when the ear lesions recurred and did not respond to glucocorticoids. To the best of the authors' knowledge, GSA with multifocal coalescing ulcerative pinnal lesions has not previously been reported.
The Amsel Vessel occluder delivered laparoscopically provides an occlusion similar to a hand-sewn transfixion suture, is simple to use, and creates an occlusion which is not only more secure, but also as safe with respect to the health of the surrounding tissues, as that of the widely used hemoclip (Ligaclip®).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
