Clostridial infections, particularly clostridial myonecrosis, can be fulminant and fatal; they often arise without an obvious history of trauma. The majority of equine clostridial myonecrosis cases are associated with intramuscular injection. This paper presents the first report of clostridial myositis by C. perfringens in a donkey after an injection of flunixin meglumine on the neck, describing the clinical, necroscopic, and histopathological events. Bacterial isolation and biochemical tests confirmed the definitive diagnosis of C. perfringens.


Clostridioses, particularmente a mionecrose clostridial, podem ser fulminantes e fatais; elas geralmente surgem sem um histórico óbvio de trauma. A maioria dos casos de mionecrose clostridial equina está associada à injeção intramuscular. Este artigo apresenta o primeiro relato de miosite clostridial por C. perfringens em jumento após injeção de flunixina meglumina no pescoço, descrevendo os achados clínicos, necroscópicos e histopatológicos. Isolamento bacteriano e testes bioquímicos confirmaram o diagnóstico definitivo de C. perfringens.

Background: Marek's disease (MD) is a transmissible disease in chickens caused by Gallid alphaherpesvirus 2 (GaHV-2). The infection is characterized by lymphocyte cellular infiltrates in peripheral nerves and other organs and tissues, including the skin; which can lead to dysfunction causing progressive asymmetric paresis and complete spastic paralysis of body extremities. Dermatitis and cardiac myositis caused by GaHV-2 in free-range chickens has rarely been described in Brazil. This reports the occurrence of the disease with a confirmatory molecular diagnosis in free-range poultry showing signs of dermatitis, poor performance, and cachexia and no mortality in the semi-arid Potiguar region. Cases: Twenty roosters of the Shamo lineage, among a brood of 42 birds, had a history of progressive weight loss and skin lesions. Two birds with poor body condition, erythema, and scaling of the skin in the head and cervical regions were sent for clinical care. All birds were between 12 and 18 months of age and were vaccinated against Newcastle disease and Fowlpox with only a few receiving vaccines against MD and Gumboro disease. According to the owner's report, some birds were previously kept outdoors, and when they were transferred to a small shed with little air circulation, they began to develop clinical signs after approximately 15 days. The first signs of the disease were also reported to have appeared 2.5 months before clinical care and, in the meantime, several treatments were instituted without success. Owing to the general condition of the animals and inconclusive clinical suspicion, the birds were subjected to euthanasia and necropsy. Tissue samples were collected for histopathological and polymerase chain reaction analyses to search for the GaHV-2 DNA meq gene. The main clinicopathological findings were erythema (47%, 20/42) and desquamation of skin and mild, prominent white multifocal areas in the heart. Histopathology revealed infiltration of pleomorphic lymphoblastic cells in the skin, heart, and sciatic nerve. The amplification of the L-meq and meq oncoprotein genes in these organs and in the liver, confirmed the infection by GaHV-2, consistent with that of a field strain. Discussion: MD was confirmed based on the macroscopic and histological lesions, and with the detection of GaHV-2 DNA in the affected tissues. The unusual clinical presentation represented an initial challenge for diagnosis. The clinical history was important to lead to the suspicion of MD, as roosters initiated clinical signs 15 days after they were transferred to a small shed with poor air circulation. This probably favored the high viral concentration and disease transmission among susceptible birds in the brood because the feather follicle is the primary site of viral replication for transmission; and desquamation of infected epithelial cells favor airborne horizontal transmission to susceptible chickens. The roosters had not been vaccinated against MD, which probably favored the infection, as vaccination is known to be a fundamental approach for MD control for effective growth of the poultry industry. Clinical findings and lesions, together with viral molecular detection, were fundamental for the diagnosis, a premise for the application of adequate prevention and control measures for the disease in breeding. This is the first report of MD with a confirmatory molecular diagnosis in northeastern Brazil.

Background: Polymyositis is a generalized inflammatory myopathy which can lead to rhabdomyolysis. This affection may have several origins, including degenerative, metabolic, autoimmune, infectious, inflammatory, ischemic, traumatic, by drug use, induced by toxins and also of idiopathic origin. Diagnosis is made with seric dosage, electrodiagnostic tests and muscle biopsy. Lesions in the rostral oblong medulla may affect the central vestibular system, and there may be signs such as opisthotonos, nystagmus, and strabismus. The aim of this report is to describe a case of a mixed breed dog with manifestation of polymyositis associated with brainstem signs of probable idiopathic origin. Case: A 5-year-old mixed breed male dog was attended with opisthotonos episodes for 2 days, and pelvic limbs extension and thoracic limbs flexion that lasted 10 to 20 min at intervals of approximately 1 h. The animal was anorexic and had also presented one episode of emesis. Upon neurological examination, ventromedial strabismus and Horner's syndrome was observed on the right side, besides vertical nystagmus, flaccid tetraparesis and absence of proprioception in the four limbs. Biochemical analyses revealed creatine kinase (CK) increased (2,433.9 UI/L - reference: 1.5-28.4 UI/L), and urinalysis showed dark color and presence of occult blood without, however, erythrocyturia. Electrocardiogram (ECG) showed QS wave and deviation of the electrical axis. Treatment with prednisolone (1 mg/kg, BID), phenobarbital (2 mg/kg, BID), maropitant citrate (1 mg/kg in 2 doses), and crystalloid fluid therapy (50 mL/kg/day) were prescribed. On the 4th day, the dog was more active and feeding without a tube, so it recommended keep the treatment at home. On the 10th day, the animal had proprioception present on the 4 limbs and normorexia. Biochemical analyses and urinalysis showed no alterations, but normochromic normochromic anemia with thrombocytopenia and leukocytosis by neutrophilia showed in blood count exam. PCR to Ehrlichia canis, Hepatozoon sp., and Babesia canis resulted negative. On the 15th day, blood count, biochemical analyses and urinalysis showed no alterations. Neurological examination revealed only positional vertical nystagmus. which remained as a sequel. Discussion: Polymyositis may be accompanied by rhabdomyolysis, characterized by acute muscle necrosis, increased CK and myoglobinuria. The animal had polymyositis of acute onset, with myoglobinuria and elevated CK values, whose presentation included myalgia and muscle weakness. In humans, polymyositis is accompanied by changes in electrocardiographic tracing without clinical alterations. In dogs, the first report that showed cardiac involvement was compatible with myocarditis. The changes in ECG in the present case was attributed to failure in myocardial electrical conduction. The patient also showed signs of brainstem and central vestibular system injuries. Stress myopathy, intoxication, snakebite, infectious, and metabolic diseases were discarded leading to a clinical suspicion as idiopathic origin. Similar to a published case, the patient of this report received symptomatic and supportive treatment, being discharged from the hospital 20 days after the onset of clinical signs. Thus, polymyositis may be accompanied by signs indicative of brainstem injury. Patients with rhabdomyolysis require intense monitoring due to the high risk of developing acute renal failure. Since no causative agent was identified, symptomatic treatment combined with the prevention of possible complications were fundamental for the maintenance of the animal's life.

Canine visceral leishmaniasis is a systemic, zoonotic disease widely spread in several countries. The disease is caused by Leishmania spp., and the dog is the main reservoir of this parasite. Clinical signs in the muscle skeletal system consist of muscle atrophy, weakness, lameness, abnormal locomotion, osteitis, polyarthritis, heat and swelling of the joints, enlarged local lymph nodes and pain. In this note, a case of canine myositis of the lumbar region associated with Leishmania spp. infection is reported. Clinical signs included weakness, fever, mild dehydration, enlarged mandibular, pre-scapular and popliteal lymph nodes and a large palpable soft mass in the lumbar region, semi-adhered and not painful. Serologic diagnosis resulted reagent by indirect immunofluorescence reaction method. Findings of ultrasonography of the lower back are described, revealing the misalignment of muscle fibers, interspersed with anechoic areas compatible with edema. Local fine needle aspiration cytology was crucial for a definitive diagnosis, revealing amastigote forms. In endemic areas of leishmaniasis, clinicians should consider this disease as a differential diagnosis in the presence of musculoskeletal injuries with no apparent cause.(AU)


A leishmaniose canina visceral é uma doença sistêmica, zoonótica e amplamente difundida causada por parasitas do gênero Leishmania spp., sendo o cão importante hospedeiro. Os sinais clínicos de leishmaniose no sistema músculo esquelético se constituem em atrofia muscular, fraqueza, claudicação, locomoção anormal, osteíte, poliartrite, hipertermia, dor e edema das articulações. A presente nota descreve um caso de miosite lombar em cão associada à infecção por Leishmania spp. Os sinais clínicos incluíram fraqueza, febre, desidratação leve, aumento dos linfonodos mandibulares, pré-escapulares e poplíteos e uma grande massa macia palpável na região lombar, semi-aderida e não dolorosa. O diagnóstico sorológico resultou em reagente pelo método da reação de imunofluorescência indireta totalmente diluída. Os achados da ultrassonografia da região lombar são descritos, revelando o desalinhamento das fibras musculares, intercaladas com áreas anecóicas, compatíveis com edema. A citologia local de aspiração por agulha fina foi crucial para o diagnóstico definitivo, revelando formas amastigotas. Nas áreas endêmicas da leishmaniose, deve-se considerar esta doença como diagnóstico diferencial na presença de lesões musculoesqueléticas sem causa aparente.(AU)

Abstract Trichinellosis is a zoonosis results from eating raw or semi-cooked meat of infected animals. Medicinal plants have been used lately as alternatives and/or combined therapies to resolve some drawbacks of the current regimens. This work analyzed the effect of albendazole monotherapy on Trichinella spiralis experimental infection (group A), in comparison to P. granatum and amygdalin extracts +cobalamin (group B), plus its combination with albendazole (group C). The study revealed that the extracts alone or combined with albendazole had an inferior effect to albendazole monotherapy regarding number of adult worms (40.83 ±3.82, 18.67 ±1.86 and 16.83 ±2.32, respectively). However, their effect was more obvious in muscle phase combined with albendazole, achieving the lower number of larvae/mL tissue homogenate (22.33 ±3.27 in comparison to 39.67 ±2.58 achieved by albendazole monotherapy). The extracts exerted a significant immunomodulatory effect by reducing the local CD4+ expression in the intestine as well as in muscle phase (1.15 ±0.25 and 3.80 ±0.65 in comparison to 4.97 ±0.37 and 12.20 ±0.87 with albendazole monotherapy, respectively). So, these extracts improved the therapeutic efficacy of albendazole, specifically in muscle phase and counteracted the inflammatory reaction caused by albendazole monotherapy, thus extensively alleviating the resulting myositis.


Resumo Trichinellosis é uma zoonose resultante da ingestão de carne crua ou semicozida de animais infectados. As plantas medicinais têm sido usadas, ultimamente, como alternativas e/ou terapias combinadas, para resolver algumas desvantagens dos regimes atuais. Este trabalho analisou o efeito da monoterapia albendazole na infecção experimental por Trichinella spiralis (grupo A), em comparação com extratos de P. granatum e amígdalina +cobalamina (grupo B), além de sua combinação com albendazol (grupo C). O estudo revelou que os extratos sozinho ou combinado com albendazol teve efeito inferior à monoterapia albendazol em relação ao número de vermes adultos (40,83 ±3,82, 18,67 ±1,86 e 16,83 ±2,32, respectivamente). No entanto, seu efeito foi mais óbvio na fase muscular combinado com o albendazol, alcançando o menor número de larvas/mL homogeneizado de tecido (22,33 ±3,27 em comparação com 39,67 ±2,58 obtidos pela monoterapia albendazol). Os extratos exerceram um efeito imunomodulatório significativo, ao reduzir a expressão local CD4+ no intestino, bem como na fase muscular (1,15 ±0,25 e 3,80 ±0,65 em comparação com 4,97 ±0,37 e 12,20 ±0,87 com monoterapia albendazol, respectivamente). Assim, esses extratos melhoraram a eficácia terapêutica do albendazol, especificamente na fase muscular e neutralizaram a reação inflamatória causada pela monoterapia albendazol, aliviando extensivamente a miosite resultante.

A dermatomiosite canina é uma vasculopatia inflamatória da pele e músculos, com manifestações cutâneas envolvendo a face, orelhas, extremidades da cauda e distais por sobre proeminências ósseas. O envolvimento muscular manifesta-se sob a forma de mioatrofia cefálica, dificuldade de deglutição, redução do reflexo do vômito e marcha atípica. A dermatomiosite canina é classificada em dermatomiosite canina familiar e em forma variante ou dermatomiosite-símile. Neste relato descreve-se um caso de dermatomiosite-símile em cadela de dois anos de idade, sem raça definida, que apresentava necrose isquêmica dos pavilhões auriculares e atrofia dos músculos temporal e masseter. O exame dermo-histopatológico realizado em fragmentos de pele dos pavilhões auriculares, região cefálica e amostras de tecido muscular (temporal e masseter) confirmou a existência de dermatite perivascular e foliculite de interface pobre em células, focos de atrofia folicular e de fibras musculares e moderada fibrose dérmica. Portanto a histopatologia, associada às manifestações clínicas do animal, permitiu o estabelecimento do diagnóstico de dermatomiosite-símile, enfermidade pouco descrita na dermatologia veterinária brasileira.(AU)

Mus-cle involvement manifests itself in the form of muscles of the head, difficulty in swallowing, reduction of reflex of vomit and atypical gait. Canine dermatomyositis is classified into variant form or dermatomyositis-like. This report describes a case of dermatomyositis-like in a two-year-old femalemixed-breed dog that presented ischemic necrosis of pinna and temporal and masseter muscle atrophy. In histopathological examinations performed with skin fragments of pinna, cephalic region and muscle samples (temporal and masseter), it was detected a perivascular dermatitis and folliculitis with poor cell interface, foci of follicular atrophy and muscle fibers with moderate dermal fibrosis confirming the diagnosis of derma-tomyositis-like, relatively little described in brazilian veterinary dermatology.(AU)

A case of blackleg in a brown brocket deer (Mazama gouazoubira) associated with trauma from being hit by a car in southern Rio Grande do Sul is reported. The clinical signs included fever, dehydration and lethargy that worsened progressively until 36 hours after the accident, when the animal died. In the fore right limb, there was a comminuted closed fracture of the radius and ulna but no skin wounds were observed. Grossly, the musculature of the pelvic limbs presented hemorrhage, edema and emphysema. Microscopically, the muscles of both rear legs had necrosis, edema, hemorrhage and mild inflammatory infiltration of neutrophils. Clostridium chauvoei was cultured from affected skeletal muscles, and it was also detected by immunohistochemistry, confirming a diagnosis of blackleg. The overlapping habitat of cattle and brown brocket deer is proposed as a predisposing factor in this case and alerts to spillover cases maybe happening in this region. In addition, blackleg should be included as differential diagnoses of deer with post-traumatic myositis.(AU)


Descreve-se um caso de carbúnculo sintomático em um veado-virá (Mazama gouazoubira), macho, jovem, resgatado após atropelamento em uma rodovia na região sul do Rio Grande do Sul. O cervídeo apresentou febre, desidratação e letargia, progredindo para a morte em 36 horas. No membro torácico direito foi observado fratura cominutiva fechada de rádio e ulna sem a presença de feridas perfurantes. Na necropsia foi observada hemorragia, edema e enfisema na musculatura dos membros pélvicos. Microscopicamente, os músculos dos membros pélvicos apresentaram necrose, edema, hemorragia e discreto infiltrado inflamatório neutrofílico. Houve o isolamento de Clostridium chauvoei e marcação positiva na técnica de IHQ com anticorpo monoclonal anti-C. chauvoei, confirmando o diagnóstico de carbúnculo sintomático. A sobreposição de habitat entre bovinos domésticos e cervídeos pode ser um fator de risco para esta doença e chama a atenção para casos de "spillover" que podem estar ocorrendo na região. Adicionalmente, sugere-se que o carbúnculo sintomático seja incluído nos diagnósticos diferenciais de cervídeos que apresentam miosite pós-traumática.(AU)

Resumo

This study aimed to review cases of blackleg (Clostridium chauvoei infection) diagnosed in cattle from Midwestern Brazil from 1994 to 2014 considering epidemiological, clinical, necropsy and histopathological findings. Also the following laboratory tests were used for the diagnosis of some cases of blackleg: microbiological culture and identification of the agent, microbiological culture and identification of the agent by the polymerase chain reaction (PCR), and identification of the agent in formalin fixed paraffin embedded tissues (FFPE). Criteria for presumptive diagnosis of blackleg included necrohemorrhagic emphysematous myositis consisting of inflammatory infiltrate, coagulative necrosis of myofiber, interstitial edema, hemorrhage, and gas bubbles between myofibers. Fifty nine cases from 51 outbreaks of blackleg were found, which corresponded to 1.1% of 5,375 cattle deaths investigated. In five of those outbreaks, samples of affected muscles cultures for the identification of pathogenic clostridia were made. Another three samples of similar material were cultured for clostridia with subsequent identification of the isolate by PCR. Twelve samples of FFPE affected muscle fragments were submitted to PCR for identification of the etiological agent. Except for January, cases were observed in each month of the year, with higher numbers in July-October. Most affected cattle were in the age of 7-12 years, but calves younger than 6 month-old and older than 24 months were also observed. Vaccination histories were scarce. In 32 outbreaks some vaccination history was available, but only in two of those vaccination has been carried out properly. In 56 six cases the skeletal muscles were involved. Muscles of the hind limbs were the most affected. In ten cases muscles of the tongue, myocardium and diaphragm were also affected. In three of the cases the visceral form was observed. Deaths occurred after a clinical course of 6-24 hours, but in most cases cattle were found death. Sudden death was the outcome in visceral cases (cardiac) blackleg. Clostridium chauvoei was confirmed to be the cause by culturing in 5 cases, and by PCR and histopatology in 8 cases. Bacterial culture followed by PCR did not demonstrate C. chauvoei. Calculation of the economic impact indicates that blackleg is a frequent disease in the state of Mato Grosso do Sul (MS) that inflicts significant economic loss. The amount of these losses would be reduced through proper vaccination programs against the prevalent strains of C. chauvoei in the region.(AU)


Este estudo foi realizado com o objetivo de descrever casos de carbúnculo sintomático (infecção por Clostridium chauvoei) diagnosticados em bovinos do Centro-Oeste brasileiro de 1994-2014, avaliando a epidemiologia, os sinais clínicos, os achados de necropsia e a histopatologia; objetivou-se também avaliar os seguintes testes laboratoriais para o diagnóstico de carbúnculo sintomático: cultura microbiológica e identificação do agente, cultura microbiológica e identificação do agente por reação em cadeia de polimerase (PCR) e identificação do agente em material fixado em formol e incluído em parafina (FFIP). Os critérios para o diagnóstico presuntivo de carbúnculo sintomático incluíram miosite necro-hemorrágica enfisematosa, caracterizada por infiltrado inflamatório, necrose de coagulação de miofribras, edema intersticial, hemorragia e bolhas de gás em meio às miofribras. Cinquenta e nove casos oriundos de 51 surtos foram encontrados, o que corresponde a 1,1% das 5.375 mortes de bovinos investigadas. Em cinco desses casos, amostras do músculo afetado foram cultivadas para clostrídios patogênicos. Amostras semelhantes de outros três animais foram cultivadas para clostrídios e os isolamentos identificados subsequentes por PCR. Doze fragmentos de músculo afetado FFIP foram submetidos a PCR para identificação do agente etiológico. Com exceção de janeiro, os casos de carbúnculo sintomático foram observados em todos os meses do ano com uma maior incidência em junho-outubro. A faixa etária da maioria dos bovinos afetados era de 7-12 anos de idade, mas bovinos mais jovens que 6 meses e mais velhos que 24 meses foram também afetados. Os históricos de vacinação eram escassos nesses surtos. Em 32 surtos havia alguma informação sobre a vacinação, mas em apenas dois casos a vacinação tinha sido realizada adequadamente. Cinquenta e seis casos de carbúnculo sintomático deste estudo eram casos clássicos afetando os músculos esqueléticos. Os músculos mais afetados foram os dos membros pélvicos. Em dez casos os músculos da língua, miocárdio e diafragma estavam também afetados. Apenas três dos casos apresentaram a forma visceral (cardíaca). O curso clínico foi de 6-24 horas, mas na maioria dos casos os bovinos foram encontrados mortos. Em casos da forma visceral ocorria morte súbita. Clostridium chauvoei foi confirmado como o agente causal por cultura em cinco casos e por PCR em amostra FFIP em 8 casos. Cultura bacteriana seguida de PCR do isolado não demonstrou C. chauvoei. Carbúnculo sintomático é uma doença frequente em bovinos no Mato Grosso do Sul podendo provocar importantes prejuízos para os produtores rurais. Esses prejuízos podem ser reduzidos através de um programa de vacinação adequado usando-se vacinas eficazes contra cepas de C. chauvoei prevalentes na região.(AU)

Muscles of the hind limbs were the most affected. In ten cases muscles of the tongue, myocardium and diaphragm were also affected. In three of the cases the visceral form was observed. Deaths occurred after a clinical course of 6-24 hours, but in most cases cattle were...(AU)


Este estudo foi realizado com o objetivo de descrever casos de carbúnculo sintomático (infecção por Clostridium chauvoei) diagnosticados em bovinos do Centro-Oeste brasileiro de 1994-2014, avaliando a epidemiologia, os sinais clínicos, os achados de necropsia e a histopatologia; objetivou-se também avaliar os seguintes testes laboratoriais para o diagnóstico de carbúnculo sintomático: cultura microbiológica e identificação do agente, cultura microbiológica e identificação do agente por reação em cadeia de polimerase (PCR) e identificação do agente em material fixado em formol e incluído em parafina (FFIP). Os critérios para o diagnóstico presuntivo de carbúnculo sintomático incluíram miosite necro-hemorrágica enfisematosa, caracterizada por infiltrado inflamatório, necrose de coagulação de miofribras, edema intersticial, hemorragia e bolhas de gás em meio às miofribras. Cinquenta e nove casos oriundos de 51 surtos foram encontrados, o que corresponde a 1,1% das 5.375 mortes de bovinos investigadas. Em cinco desses casos, amostras do músculo afetado foram cultivadas para clostrídios patogênicos. Amostras semelhantes de outros três animais foram cultivadas para clostrídios e os isolamentos identificados subsequentes por PCR. Doze fragmentos de músculo afetado FFIP foram submetidos a PCR para identificação do agente etiológico. Com exceção de janeiro, os casos de carbúnculo sintomático foram observados em todos os meses do ano com uma maior incidência em junho-outubro. A faixa etária da maioria dos bovinos afetados era de 7-12 anos de idade, mas bovinos mais jovens que 6 meses e mais velhos que 24 meses foram também afetados. Os históricos de vacinação eram escassos nesses surtos. Em 32 surtos havia alguma informação sobre a vacinação, mas em apenas dois casos a vacinação tinha sido realizada adequadamente. Cinquenta e seis casos de carbúnculo sintomático deste estudo eram casos clássicos afetando os músculos esqueléticos. Os músculos mais...(AU)

Background: Dermatomyositis is an idiopathic, inflammatory/immunemediated disease of the skin, muscles and blood vessels of hereditary nature and unclear pathogenesis. This familial disease has been described in certain breeds, especially collies and Shetland sheep dogs and is of rare occurrence in mongrel dogs. To describe and discuss three clinical cases of dermatomyositis-like disease and provide a brief review of the literature.Cases: Three young mongrel dogs are included in this report. Case 1: Mandarino, a 4-year-old mongrel dog, having a history of skin lesions for at least a year. Showed an underweight patient, skin ulcers, crusts, alopecia, peri-ocular scarring causing severe lagophthalmia and a corneal ulcer. Muscle atrophy was most notable in the head and legs; the dog had difficulty and pain walking. Treatment was initialised with cephalexin 30 mg/kg BID, pentoxifylline 25 mg/kg BID, and prednisone 2.2 mg/kg SID. The patient was presented after two weeks for follow up; the anaemia and skin condition had improved, the weight had increased by 2 kg, dysphagia and locomotor abnormalities were not present. Case 2: Milagros, a mongrel female dog approximately two years of age, rescued from a shelter. Physical examination showed facial alopecia, erythema and scarring of the periocular skin, crusting and scaling in alopecic areas, pinnae tip necrosis and crusting, ear alopecia, tail tip necrosis and crusting. Also present were distal limb alopecia, crusting and ulcers in areas of trauma in the hock and carpal surfaces; some nails presented onychorhexis and onychoschizia. The patient has been treated for 12 months with a good clinical outcome, with pentoxifylline, azathioprine 2.2 mg/kg EOD alternating with prednisone 1 mg/kg EOD. Case 3: Chuchito, an 11-month-old male mongrel rescued dog had been previously hospitalised due to his skin condition.[...]

Purpose:To analyze the topical effects of Buriti oil (Mauritia flexuosa L.) in induced myositis in rats.Methods:Thirty six male rats divided into three groups: Control group (C), induced myositis group (MI) and induced myositis group reated with Mauritia flexuosa L. (MT). After inducing myositis with 1% acetic acid, was topically applied 0.5 ml of Mauritia flexuosa L.extract on the posterior region of the right gastrocnemius muscle in animals belonging to group MT, for 7 and 14 days.Results:The neutrophil number there was statistically significant difference, after 7 and 14 days, between groups C and MI (p <0.001) (p<0.01). The group MT there was a significant difference in relation to MI group in both experimental times with (p<0.001). The number of fibroblasts in the 14 days showed that when comparing the groups M and MT the differences were also significant (p<0.001). As for the DLL, in 7 days, there was a significant difference between group C and MI group (p <0.001). When considering the MT group, there was a significant difference in relation to the MI group (p <0.001).Conclusion:The extract of Mauritia flexuosa L. leaves lessened acute and chronic inflammation, increased fibroblast proliferation and reduced macroscopically edema.(AU)

PURPOSE: To analyze the effects of the low-level laser therapy in the acute myositis induced in rats. METHODS: Twelve rats were subjected to bilateral ovariectomy for inducing osteoporosis. After surgery, they were divided into two groups: Ovariectomy-control group (G1, n=6), receiving 0.5 ml distilled water by gavage for 30 days, and Ovariectomy plus mastruz group (G2, n=6), receiving 0.5 ml of the hydroalcoholic extract of mastruz at 10% concentration (50mg) daily, for the same period. Then, the blood of the animals was collected for further biochemical analysis (liver function) and tibia and liver were removed for histological and histomorphometric analyses. RESULTS: In the MT group there was a statistic significant decrease in the number of inflammatory cells, related to the MI group (p 0.05), increase in the fibroblastic proliferation, when compared to groups C and MI related to MT group (p 0.01) and statistic significant edema regression (p=0.0400) in the MT group CONCLUSION: The low-level laser therapy was efficient in the reduction of the inflammatory process, increase of the fibroblastic proliferation and the reduction of the edema.(AU)

Resumo

Miosite eosinofílica é uma condição inflamatória relativamente rara que afeta os músculos estriados de bovinos e ovinos. A lesão é usualmente associada a cistos degenerados de Sarcocystis spp., principalmente S. cruzi embora esse protozoário ocorra associado às miofibras de praticamente qualquer bovino, sem provocar, na grande maioria das vezes, reação inflamatória. Esse artigo relata os achados macro e microscópicos da miosite eosinofílica em três bovinos abatidos para produção de carne para consumo humano. Macroscopicamente, as lesões consistiam de manchas ou linhas amarelo-pálidas, ocasionalmente esverdeadas, de 2-6mm no miocárdio de três bovinos e no músculo masseter de um deles. Microscopicamente, as lesões consistiam de acúmulos inflamatórios granulomatosos circundando um centro constituído por eosinófilos mortos e degenerados e ocasionais fragmentos de Sarcocystis sp. A imuno-histoquímica realizada no miocárdio de um dos bovinos com um anticorpo policlonal anti-Neospora caninum marcou cistos intactos em miofibras normais e fragmentos de cistos em meio a áreas de intensa reação inflamatória. Esse último achado corrobora a opinião dos que apontam Sarcocystis sp. como tendo participação na causa da miosite eosinofílica. (AU)


Eosinophilic myositis is a relatively rare inflammatory condition affecting striated muscle of cattle and sheep. It has been usually associated with degenerating cysts of Sarcocystis spp., mainly S. cruzi, although this protozoan occurs in the myofibers of almost every cattle without provoking an inflammatory reaction. This paper reports the gross and histopathological findings of eosinophilic myositis in three cattle slaughtered for meat production for human consumption. Grossly lesions were pale yellow, occasionally with a greenish hue, 2-6mm spots or strikes in the myocardium of the three cattle and in the masseter muscle of one of them. Microscopically there were granulomatous lesions surrounding a core of dead and degenerating eosinophils and occasional fragment components of Sarcocystis. Immunohistochemistry performed with a policlonal anti-Neospora caninum antibody in the myocardium of one of the cattle marked intact cysts in normal myofibers and intralesional fragments of disrupted cyst amidst areas with strong inflammatory reaction. This latter finding corroborates the opinion of those in favor of Sarcocystis spp. playing a role in the causation of eosinophilic myositis. (AU)

A tromboflebite jugular equina (TJE) é uma das doenças vasculares mais frequentes em equinos. Geralmente está associada a processos iatrogênicos que levam a lesões mecânicas ou químicas dos vasos, como as injeções perivasculares acidentais. Dentre os sinais clínicos, podem estar presentes edema, ingurgitamento cranial ao trombo e dor a palpação com aumento de temperatura local. A ultrassonografia pode fornecer informações precisas sobre as condições da musculatura adjacente, espessura da parede de vaso afetada e possível presença de trombos, assim como avaliar a hemodinâmica do vaso. O objetivo desde relato é descrever os achados clínicos, ultrassonográficos e hemodinâmicos da TJE em um paciente que apresentava aumento de volume na região cervical, aumento da temperatura local e dor a palpação. No exame ultrassonográfico detectou-se áreas hipoecóicas e hiperecóicas na musculatura local, veia jugular com parede espessada, presença de vasos colaterais e negativo ao exame de Collor Doppler, sendo diagnosticada tromboflebite unilateral direita e miosite perivascular. Conclui-se que o exame ultrassonográfico é importante na confirmação do diagnóstico e prognóstico no paciente equino com tromboflebite da jugular.


Equine jugular thrombophlebitis (EJT) is one of the most frequent vascular diseases in horses. It is usually associated with iatrogenic processes that lead to mechanical or chemical vessel damage, such as accidental perivascular injections. Clinical signs may include edema, cranial engorgement to the thrombus and palpation pain with increased local temperature. Ultrasonography can provide accurate information on adjacent musculature conditions, extentesion of vessel wall affected, and possible presence of thrombi, as well as assessing vessel hemodynamics. The purpose of this report is to describe the clinical, ultrasonographic and hemodynamic findings of ECJ in a patient with increased volume in the cervical region, increased local temperature and palpation pain. Ultrasonographic examination revealed hypoechoic and hyperechoic areas in the local musculature, jugular vein with thickened wall, presence of collateral vessels and negative Collor Doppler examination, diagnosed right unilateral thrombophlebitis and perivascular myositis. It is concluded that the ultrasound examination is important in confirming the diagnosis and prognosis in the equine patient with jugular thrombophlebitis.


Una tromboflebitis yugular equina (TYE) es una enfermidad vascular muy séria, quizá sea la más frecuentes en los equinos. Generalmente es responsable por procesos iatrogénicos que llevan a lesiones mecánicas o químicas de los vasos, como las jeringas perivasculares acidentales. Los síntomas más comunes son edemas, ingurgitación craneal al trombo y dolor a palpación con aumento de temperatura local. La mejor manera de buscar informaciones precisas de las condiciones de la musculatura adyacente, el espesor de la pared del vaso afectada y posible presencia de trombos, así como evaluar la hemodinámica del vaso, es haciendo una ultrasonografia. El objetivo de esta investigación es buscar casos clínicos ultrasonográficos y hemodinámicos del TYE en un paciente que presentaba aumento del volumen en la región cervical, aumento de la temperatura local y dolor a palpación. A traves del examen ultrasonográfica pudireon detectarse áreas hipoecóicas e hiperecóicas en la musculatura local, vena yugular con pared espesa, presencia de vasos colaterales y resultado negativo al examen de Collor Doppler, siendo diagnosticada tromboflebitis unilateral derecha y miositis perivascular. Se puede concluir que el examen ultrasonográfico es importante en confirmación de diagnóstico y pronóstico en paciente equino con tromboflebitis de la yugular.

Resumo

Fibrodysplasia ossificans progressiva-like (FOP-like) was diagnosed in a young Brazilian cat presenting progressive lameness, pain upon manipulation and inability to extend the hind limbs. Due to poor response to medication described in the literature, only orchiectomy and confinement of the patient were recommended. The patient described here has been observed for four years and the animal is currently in fair condition despite the movement restrictions.(AU)


Fibrodisplasia ossificante progressiva (FOP)-like foi diagnosticada em um felino brasileiro jovem com claudicação progressiva, atrofia, incapacidade de extensão e dor a manipulação dos membros pélvicos. Em razão de insuficiência nas respostas aos medicamentos observados na literatura foi preconizado apenas orquiectomia e confinamento do paciente. Apesar de a maioria dos relatos de FOP-like indicar eutanásia, o presente caso está sendo acompanhado há quatro anos, desde o diagnóstico, e apesar de o paciente manter-se com restrições de deambulação, encontra em condições satisfatórias.(AU)
