Photodynamic Therapy for Pododermatitis in Penguins

Pododermatitis is currently one of most frequent and important clinical complications in seabirds kept in captivity or in rehabilitation centers. In this study, five Magellanic penguins with previous pododermatitis lesions on their footpad were treated with photodynamic therapy (PDT). All PDT treated lesions successfully regressed and no recurrence was observed during the 6-month follow-up period. PDT seems to be an inexpensive and effective alternative treatment for pododermatitis in Magellanic penguins encouraging further research on this topic. (C) 2014 Wiley Periodicals, Inc.

Incidência das dermatopatias auto-imunes em cães e gatos e estudo retrospectivo de 40 casos de lupus eritematoso discóide atendidos no serviço de dermatologia da Faculdade de Medicina Veterinária e Zootecnia da UNESP – Botucatu

The objectives of this study were to do a survey of the autoimmune skin diseases and update the records regarding the occurrence of discoid lupus erythematosus in canine and feline populations attended at the Dermatology Service of the College of Veterinary Medicine and Animal Science of UNESP - Botucatu, including species, gender, breed, age, location and characteristic of the lesions. Results have shown that the order of occurrence, regarding the number of cases of autoimmune skin diseases in the animals attended by the Dermatology Service in the period from 1988 to 2007 was: discoid lupus erythematosus, pemphigus folliaceus, uveo-dermatologic syndrome, pemphigus vulgaris, systemic lupus erythematosus, necrolytic migratory erythema, multiforme erythema and plasmacytic pododermatitis. All the animals with discoid lupus erythematosus were dogs and most of them were mongrel females. More frequently breeds affected by discoid lupus erythematosus were german shepherd and akita and the mean age was 56 months. Most lesions were located in nasal planum, narines and periocular area and were characterized by crusting, depigmentation and erythema.

Observações clínicas, anatomopatológicas e tratamento de seis casos de dermovilite exsudativa vegetante crônica (cancro da ranilha) de cqüinos

Chronic hypertrophic pododermatitis cases in six horses of different breeds, aging 14 months to 19 years are described. The lesion begun with a infiltrative tissue in the frog and sole regions of the hoof, characterized by a fast and disorganized growth, with a papillary aspect, white colored in the roots and dark on the extremity, with a necrotic secretion and an extremely fetid odor. Microscopically, an exuberant epidermic proliferative tissue was observed, intermingled with little connective tissue. The horses were divided into two treatment groups. In the first group, including three young mares and a foal, showing lesions in only one limb, a surgical resection of the invasive mass was performed, followed by cauterization of the remaining edges and subsequent daily local application of antiseptic substances. In three of these horses, recurrence of the initial lesion occurred, with fast growth of hyperplasic tissue, affecting almost all the frog and half of the sole. Two horses developed contraction deformities of the hoof. In the second group, one male and one female, each with lesions in two limbs, after surgical debridement of the tissue, the animals received daily applications of picric acid 5%, associated to local use of oxitetracyclin. Although one of these cases required a second surgical intervention for removal of the mass, the horses showed after a period of two to three months total absence of the infiltrative tissue. The use of local picric acid 5% and oxitetracyclin associated to previous surgical debridement showed to be more efficient than the use of antiseptic substances in the treatment of chronic hypertrophic pododermatitis.

Exogenous bacterial osteomyelitis in 52 dogs: a retrospective study of etiology and in vitro antimicrobial susceptibility profile (2000-2013)

Background: Most clinical cases of osteomyelitis in dogs involve infectious agents, especially bacteria and fungi. The characterization of these microorganisms may aid in the prevention and treatment of disease.Objective: The aim of this study was to evaluate retrospectively microbiological cultures and in vitro antimicrobial susceptibility profile of isolates from 52 cases of bacterial osteomyelitis in long bones of dogs over 2000-2013. In 78% of the cases injuries were caused by a motor vehicle accident, but there were a few cases of dog bites (17%) and ascending infection due to pododermatitis (5%).Animals and methods: The isolated microorganisms were identified based on conventional phenotypic methods. In vitro disk diffusion test was performed using 30 different antimicrobials.Results: The isolates were obtained from femur (28%), humerus (16%), tibia (31%), and radius/ulna (25%). Among 52 cases, culture was positive in 88% of cases. Thirteen genus of different species of microorganisms were isolated. The most common microorganisms isolated were Staphylococcus spp. and Escherichia coli followed by Streptococcus spp., enteric bacteria, Corynebacterium sp. and anaerobic bacteria. In 42% of cases cultures were mixed. The most effective drugs against isolated bacteria were amoxicillin and clavulanate potassium (79%) followed by ceftriaxone (69%). High-resistance rates were documented against azithromycin (80%), penicillin (59%), and clindamycin (59%).Conclusions: The present study highlights diverse etiologic agents in cases of infectious bacterial osteomyelitis, with predominance of Staphylococcus genus, and reinforces the importance of obtaining cultures and susceptibility profiles given the high rates of antimicrobial resistance.
