Retrospective study of thoracolumbar ventral fenestration through intercostal thoracotomy and paracostal laparotomy in the dog

Foram analisados os resultados da fenestração ventral dos discos toracolombares em 29 cães agrupados segundo a raça, sexo, peso, idade, graus de déficits neurológicos, duração dos sinais, discos intervertebrais envolvidos, tempo para recuperação e porcentagem de sucesso. A raça Dachshund representou 55,18% (n = 16), cães sem raça definida, 13,8% (n = 4), Poodle e Basset Hound e Cocker Spaniel Inglês 6,89% cada (n = 6), e Pastor Alemão, Beagle e Pinscher, 3,45% cada (n = 3), sendo 51,72%, machos e 48,28%, fêmeas, com idade média de 68,03 meses. O grau de déficits neurológicos correspondeu a: 13,8% dos cães pertencentes ao GI (dor), 41,8% ao GII (paresia), 27,6% ao GIII (paraplegia com dor profunda presente) e 17,2% ao GIV (paraplegia com dor profunda ausente). Os sinais clínicos variaram em duração entre 2 e 60 dias, correspondendo às médias de 18,5 (GI), 12,3 (GII), 8,28 (GIII) e 4,2 dias (GIV). A porcentagem de discos intervertebrais acometidos foi: T10/11 (10,81%), T11/12 (24,33%), T12/13 (40,55%), T13/L1 (16,21%) e L1/2, L2/3 e L3/4, 2,7% cada. O tempo médio de recuperação, em dias, foi: 16 (GI), 19,1 (GII), 20,6 (GIII) e 30,6 (GIV), onde 100% dos animais dos grupos I, II e III recuperaram ambas as funções neurológicas e motoras. O grupo IV apresentou 80% de sucesso. Conclui-se que a fenestração ventral produz excelentes resultados pós-operatórios desde que bem selecionados os casos.

Quantitative comparison of mobility and gross motor function in Brazilian children with cerebral palsy

Background: Cerebral palsy (CP) presents changes in posture and movement as a core characteristic, which requires therapeutic monitoring during the habilitation or rehabilitation of children. Besides clinical treatment, it is fundamental that professionals use systems of evaluation to quantify the difficulties presented to the individual and assist in the organization of a therapeutic program. The aim of this study was to quantitatively verify the performance of children with spastic di-paresia type CP.Methods: The Pediatric Evaluation of Disability Inventory (PEDI) and Gross Motor Function Classification System (GMFM) tests were used and classification made through the GMFCS in the assessment of 7 patients with CP, 4 females and 3 males, average age of 9 years old.Results: According to GMFCS scales, 17% (n=1) were level II and 83% (n=6) were level III. The PEDI test and 88 GMFM items were used in the area of mobility. We observed that there was high correlation between mobility and gross motor function with Pearson's correlation coefficient =0.929) showing the likely impact of these areas in the functional skills and the quality of life of these patients.Conclusion: We suggest the impact of the limitation of the areas in functional skills and quality of life of these patients.

Lesões sequelares na laringe em pacientes com paracoccidiodomicose

A Paracoccidioidomicose (PCM) é uma doença sistêmica que em sua forma sequelar se caracteriza por manifestações clínicas relacionadas às alterações anatômicas ou funcionais de órgãos e sistemas comprometidos no período de estado. OBJETIVO: Descrever as alterações anatômicas e funcionais laríngeas sequelares em pacientes com paracoccidioidomicose. MATERIAL E MÉTODOS: Estudo retrospectivo, sendo avaliados 49 pacientes do sexo masculino, na faixa etária de 30 a 60 anos, entre 1999 a 2004, com diagnóstico de PCM em acompanhamento pela disciplina de Moléstias Infecciosas e Parasitárias, confirmado pela demonstração do fungo em escarro, exame citológico ou histopatológico. RESULTADOS: As pregas vocais foram a estrutura laríngea mais afetada, em 67% dos pacientes verificaram-se alterações. A epiglote estava acometida em 55% dos casos. As pregas ariepiglóticas tinham modificações em 53% dos pacientes. As pregas vestibulares estavam alteradas em 46% dos casos. em 40% dos casos verificaram-se alterações em aritenoides. Na fonação, 28% tinham limitação ao movimento das cordas vocais, paresia unilateral ocorreu em 4% casos. em 24% havia restrição da luz supraglótica e 4% tinham estenose glótica, sendo que 2% precisaram de traqueotomia. CONCLUSÃO: As lesões sequelares na laringe devido à infecção pelo P. brasilienses são extensas e causam restrições funcionais na maioria dos casos.

Surtos de botulismo em bovinos no Brasil associados à ingestão de água contaminada

Botulismo em bovinos resulta da ingestão de toxina previamente formada. No presente trabalho são descritos sete surtos da intoxicação onde os dados clínico-patológicos, epidemiológicos e os achados laboratoriais indicaram a possível ingestão da toxina através da água contaminada. O coeficiente médio de mortalidade foi de 20,1%, com letalidade de 99,92%, e morbidade de 31,62%. Dos cerca de 9.000 bovinos envolvidos nos surtos, 2.844 morreram com quadro clínico predominantemente superagudo e agudo. A alta morbidade e mortalidade foram registradas num curto período de tempo e envolveram todas as categorias animais, com quadro clínico-patológico caracterizado por paresia e paralisia da musculatura da locomoção, deglutição e mastigação e ausência de lesões macroscópicas. As circunstâncias em que ocorreram os surtos estiveram relacionadas com a existência de carcaças de animais decompostas ou matéria orgânica vegetal na água de dessedentação. Foram detectadas toxinas botulínicas C e/ou D nas coleções de água, nas vísceras e no soro sangüíneo de parte considerável dos materiais examinados.

Utilização da acupuntura no tratamento de cães com discopatia intervertebral

The intervertebral disc diseases have a high casuistic in clinical routines veterinary among dogs. These conditions can cause pain, paresis or paralysis of limbs depending on the degree of injury. Clinical signs are not limited to the intervertebral disc, other anatomical parts are included. In conventional medicine, treatment may be surgical or clinical, by the use of corticosteroids with muscle relaxants. Acupuncture was an alternative to treating these diseases due to its anti-inflammatory and analgesic effects. Although there are few studies for the treatment of discopathies, acupuncture triggers the release of substances such as dynorphins, beta-endorphins and serotonin, among others; that act inhibiting somatic and visceral pain. Electroacupuncture is used to potentiate the effects of acupuncture. It can be performed with different frequencies according to the clinical evolution. However there are different opinions related to the greater efficacy in relation to acupuncture. The restraint and monitoring of the treated animal are important factors for its recovery. The association between acupuncture and conventional treatment (surgical or clinical) achieved better results than acupuncture alone. This proves that acupuncture can be considered an option in order to minimize the complications of surgery or assist in patient recovery

Tromboembolismo na aorta abdominal terminal em felinos

Clinical manifestations of arterial thromboembolism in cats depends on the location of embolization, the severity and duration of occlusion, the functionality of the collateral circulation and the development of complications. In case of location in the terminal abdominal aorta usually presents animal paresis/paralysis, pulses are weak or nonpalpable, pain, cold limbs. Gastrocnemius and tibialis muscles generally have become bulbous, swollen and sore because of ischemic neuromyopathy. The nail beds become pale or very dark (purple to black), and do not bleed when cut. Due to the small number of researches in the area it’s until not possible to determine which medication, dosage and frequency of administration are more suitable for the treatment of arterial thromboembolism in cats. Among the options currently available the cheapest, easiest to administer and which requires no periodic monitoring is the low-dose aspirin

Functional neurologic recovery in two dogs diagnosed with severe luxation of the vertebral column

Traumatic injuries to the vertebral column, spinal cord, and cauda equina nerve roots occur frequently in human and veterinary medicine and lead to devastating consequences. Complications include partial or complete loss of motor, sensory, and visceral functions, which are among the main causes of euthanasia in dogs. The present case report describes neurological functional recovery in two dogs that were treated surgically for severe spinal fracture and vertebral luxation. In the first case, a stray, mixed breed puppy was diagnosed with thoracolumbar syndrome and Schiff-Scherrington posture, as well as a T13 caudal epiphyseal fracture with 100% luxation between vertebrae T13 and L1; despite these injuries, the animal did show deep pain sensation in the pelvic limbs. Decompression through hemilaminectomy and spinal stabilization with vertebral body pins and bone cement were performed, and the treatment was supplemented with physiotherapy and acupuncture. In the second case, a mixed breed dog was diagnosed with a vertebral fracture and severe luxation between L6 and L7 after a vehicular trauma, but maintained nociception and perineal reflex. Surgical stabilization of the spine was performed using a modified dorsal segmental fixation technique Both patients showed significant recovery of neurological function. Complete luxation of the spinal canal observed radiographically does not mean a poor prognosis, and in some cases, motor, sensory, and visceral functions all have the potential for recovery. In the first case the determining factor for good prognosis was the presence of deep pain perception, and in the second case the prognosis was determined by the presence of sensitivity and anal sphincter tone during the initial neurological examination.
