Relação entre a biometria ultra-sonográfica em modo B do bulbo ocular e os diâmetros fronto occiptal e bizigomático em Canis familiaris

Avaliou-se 31 cães saudáveis, sem raça definida, sendo 10 machos e 21 fêmeas, com 8 meses a 7 anos de idade e peso de1,5-28 kg. Inicialmente foram mensurados os diâmetros fronto-occiptal (DFO) e bizigomático (DBZ) do crânio com o auxílio de um paquímetro. A ultra-sonografia transpalpebral em modo-B foi realizada para mensurar as estruturas do bulbo ocular, conforme se segue: D1- espessura da córnea; D2- distância entre o ponto central da imagem da córnea e a da cápsula anterior do cristalino (câmara anterior); D3- distância entre o ponto central da imagem da córnea e a da cápsula posterior do cristalino; D4- espessura do cristalino, que corresponde a distância entre a imagem da cápsula anterior e a cápsula posterior do cristalino; D5- diâmetro do cristalino, distância entre as imagens dos pólos do cristalino; D6– área do cristalino; D7- câmara vítrea, distância entre a imagem da cápsula posterior do cristalino e a retina; D8- distância entre a cápsula anterior do cristalino e a retina; D9- distância entre a imagem da córnea e a retina. Com exceção da D4, houve efeito dos DFO e DBZ sobre as medidas das estruturas internas do BO. A análise de regressão linear entre as medidas das estruturas do bulbo ocular e os DFO e DBZ foram significativas para D1, D2, D3, D4, D5, D6, D7, D8 e D9.

Protetor ocular para aplicações de fototerapia em recém-nascidos

O protetor ocular é executado em qualquer material resistente opaco, estéril ou esterelizado, como tela de algodão, película ou filme flexível plástico, ou fibra celulósica prensada, ou ainda uma conjugação desses materiais, com conformação anatômica possibilitando sua aposição superficial às órbitas oculares, adaptando-se, por meio de um recorte em sua porção mediana, à projeção do nariz. O protetor constitui de um tampão posicionado sobre as órbitas oculares, um cordão ou fita de fixação e um passante ou ranhura para a passagem do cordão de fixação.

Avaliação ultrassonográfica do bulbo ocular em cães submetidos à facoemulsificação com ou sem implante de lente intraocular

This study aimed to describe and compare the ultrasonographic alterations in dogs' eyes submitted to facectomy with or without intraocular lens implant (IOL), to assist in the diagnosis of possible alterations related to the surgical procedure and IOL implantation. Nineteen dogs with cataract (21 eyes) were submitted to phacoemulsification and late postoperative evaluation (at five years). The animals were initially submitted to complete ophthalmological exams which preceded the sonogram. Dogs were divided in three groups: (CA) aphakic dogs (n= 11); (PP) pseudophakic dogs with implantation of two IOLs in piggyback (n=5) and (PL) pseudophakic dogs with implantation of a veterinary IOL (n = 5). The ultrasound was carried under the administration of a topic local anesthetic, with a multi frequency linear transducer of 10 MHz. Biometric eye measurements were also performed. The clinical alterations observed were IOL dislocation, retinal detachment, asteroid hyalosis, and vitreous degeneration. Ultrasound examination was an excellent diagnostic tool, as it was possible to confirm and classify these changes. The piggyback implant reduced the measurements between the ciliary body and the vitreous chamber obtained from the ocular biometry when compared to other usual procedures, with no difference between the axial length and the anterior chamber.

The Primary Closure Approach of Dog Bite Injuries of the Nose

The nose holds an outstanding position on the face, acquiring great importance within the context of facial aesthetics. Because of the functional, psychological, and social aspects of trauma in a society increasingly demanding about aesthetics, treatment institution must reduce, as accurate as possible, the sequelae that hinder social integration. This clinical report relates an immediate nasal reconstruction of a complex animal bite wound. A 7-year-old patient was victim of a dog bite with avulsion of the left nasal ala and part of the ipsilateral nasal tip. The treatment was immediate nasal reconstruction with auricular composite graft. After 1 year of follow-up, the shape of nasal ala was stable, and the color was consistent with the surrounding tissue. The 2 nasal sides exhibited satisfactory symmetry when evaluated. It can be concluded that the composite graft derived from the auricular helix is a safe option for reconstruction of nasal ala defects with compromised margins in pediatric patients when conditions of reimplantation do not exist.

Injuries by marine and freshwater stingrays: history, clinical aspects of the envenomations and current status of a neglected problem in Brazil

Stingrays are a group of rays - cartilaginous fish related to sharks - that have whiplike tails with barbed, usually venomous spines and are found around the world, especially the marine species. Despite recent reports of accidents involving these fish, they are not aggressive, reacting only when stepped on or improperly handled. Injuries by stingrays are seldom mentioned by historians, although they have always been present in riverine communities of inland waters and in South American coasts. Indeed, envenomations by stingrays are quite common in freshwater and marine fishing communities. Although having high morbidity, such injuries are neglected because they have low lethality and usually occur in remote areas, which favor the use of folk remedies. In the present review article, historical aspects of injuries caused by stingrays in Brazil and their distribution on the coast of Sao Paulo state and riverine communities of the North, Midwest and Southeast regions were studied. In addition, other aspects were analyzed such as clinical features, therapeutic methods, preventive measures and trends in occurrence of these accidents in the country, particularly in areas in which freshwater stingrays had not been previously registered, being introduced after breaching of natural barriers.

Treatment of osteochondral injuries with platelet gel

OBJECTIVES: Treatments for injured articular cartilage have not advanced to the point that efficient regeneration is possible. However, there has been an increase in the use of platelet-rich plasma for the treatment of several orthopedic disorders, including chondral injuries. Our hypothesis is that the treatment of chondral injuries with platelet gel results in higher-quality repair tissue after 180 days compared with chondral injuries not treated with gel.METHODS: A controlled experimental laboratory study was performed on 30 male rabbits to evaluate osteochondral injury repair after treatment with or without platelet gel. Osteochondral injuries were surgically induced in both knees of each rabbit at the medial femoral condyle. The left knee injury was filled with the platelet gel, and the right knee was not treated. Microscopic analysis of both knee samples was performed after 180 days using a histological grading scale.RESULTS: The only histological evaluation criterion that was not significantly different between treatments was metachromasia. The group that was treated with platelet gel exhibited superior results in all other criteria (cell morphology, surface regularity, chondral thickness and repair tissue integration) and in the total score.CONCLUSION: The repair tissue was histologically superior after 180 days in the study group treated with platelet gel compared with the group of untreated injuries.

Manifestações oculares na leishmaniose

The Canine Visceral Leishmaniasis is a chronic disease of endemic character, caused by Leishmania Chagasi in Americas. The inoculation of the promastigote form in the individual triggers a local and widespread immune reaction with formation of inflammatory infiltrates and deposition of immune complexes in tissues. Initial clinical symptoms of the disease are: weight reduction, hepatomegaly, splenomegaly and, according to the disease chronicity, signs such as alopecia, erythema, onychogryphosis, arthropathies, renal diseases, pyoderma, seborrheic dermatitis, muscle atrophy and Ocular diseases. Ocular diseases are often reported and are result of the direct parasitism or immune-mediated mechanisms caused by the disease. The Leishmania spp have greater affinity for the anterior segment, so that anterior uveitis is one of the most frequently diagnosed injuries. Blepharitis diffuse and Keratoconjunctivitis also appear as important ocular changes. In histological section, inflammatory infiltrates and macrophages with amastigote form are observed in all ocular tissues, with the exception of the retina and optical nerve. In the clinical analysis and disease diagnosis, should be considered the differential diagnosis, such as Ehrlichiosis and systemic hypertension, because these may cause some ocular manifestations similar to those observed in leishmaniasis
