Molecular and antigenic analyses of three influenza viruses isolated from outbreaks of severe respiratory disease in racing greyhounds revealed that they are closely related to H3N8 equine influenza virus. Phylogenetic analysis indicated that the canine influenza virus genomes form a monophyletic group, consistent with a single interspecies virus transfer. Molecular changes in the hemagglutinin suggested adaptive evolution in the new host. The etiologic role of this virus in respiratory disease was supported by the temporal association of rising antibody titers with disease and by experimental inoculation studies. The geographic expansion of the infection and its persistence for several years indicate efficient transmission of canine influenza virus among greyhounds. Evidence of infection in pet dogs suggests that this infection may also become enzootic in this population.

A consensus nested-PCR method was designed for investigation of the DNA polymerase gene of adenoviruses. Gene fragments were amplified and sequenced from six novel adenoviruses from seven lizard species, including four species from which adenoviruses had not previously been reported. Host species included Gila monster, leopard gecko, fat-tail gecko, blue-tongued skink, Tokay gecko, bearded dragon, and mountain chameleon. This is the first sequence information from lizard adenoviruses. Phylogenetic analysis indicated that these viruses belong to the genus Atadenovirus, supporting the reptilian origin of atadenoviruses. This PCR method may be useful for obtaining templates for initial sequencing of novel adenoviruses.

To test 4 previously published outcomes instruments (the Facelift Outcomes Evaluation, the Rhinoplasty Outcomes Evaluation, the Blepharoplasty Outcomes Evaluation, and the Skin Rejuvenation Outcomes Evaluation) in terms of their reliability and validity in assessing patient-related outcomes of surgical intervention.Design: A prospective pilot study of 78 patients in 3 similar private cosmetic surgery centers undergoing a total of 100 face-lift, rhinoplasty, blepharoplasty, and skin rejuvenation procedures. Patients were evaluated at 2 preoperative and 1 postoperative time points and the instruments were analyzed with regard to their test-retest reliability, internal consistency, and responsiveness to change.Results: All 4 outcomes instruments had excellent reliability, consistency, and validity scores. Test-retest re-liability was 0.74 to 0.83 (Pearson correlation coefficients), internal consistency scores were .83 to .88 (Cronbach ␣), and responsiveness to change was statistically significant for each instrument tested (PՅ.001). In addition, patients experienced significant quality of life improvement, with overall satisfaction increasing on average from 37% to more than 84% after these procedures.Conclusions: These 4 instruments are reliable and valid and can be used to accurately assess patient-related satisfaction in studies of face-lift, rhinoplasty, blepharoplasty, and skin resurfacing outcomes. These brief questionnaires provide the cosmetic surgeon with quantitative tools to evaluate otherwise subjective and purely qualitative outcomes and are recommended for use in future prospective studies.

Cats naturally infected with feline immunodeficiency virus (FIV) develop an AIDS-like syndrome whereas experimentally infected cats do not. To investigate the role of cofactors in the development of this disease in cats, 7 specific pathogen-free (SPF) and 12 random-source (RS) cats were infected with FIV. Over 4 years, infected cats developed similar phenotypic and functional immune abnormalities characterized by early and chronic inversion of CD4+:CD8+ cell ratios and significantly decreased mitogen responses compared with controls. Beginning 18-24 months after infection, 10 RS cats developed chronic clinical disease typical of feline AIDS, including stomatitis and recurrent upper respiratory disease; 4 SPF cats also developed chronic clinical disease, 2 with neurologic disease and 2 with B cell lymphomas. Thus, immunologic background is important in the type of disease that develops in cats infected with FIV, and FIV represents a promising animal model for studying the immunopathogenesis of AIDS in humans.
