Malformations and possible damages to the urogenital system can be originated in the embryonic period. Moreover, fire guns, knives and accidents, where there is the disruption of the urethra, also cause these lesions. The objective was to analyze the contribution of tissue engineering in the construction of neo-urethra, developed by bioengineering. We performed an urothelial ex vivo expansion of cells in 3D scaffolds (platelet gel matrix and acellular porcine aorta) to assess the contribution of this technique in the construction of a neo-urethra. Mechanical dissociation was made of the inner wall of 10 North Folk rabbit’s bladder, weighing 2.5 to 3.0 kg. After dissociation the cell content was centrifuged and obtained a pellet of urothelial cells. The pellet was ressuspended in culture medium DMEM F12 and cells were maintained in culture for 15 days. Immunohistochemical analysis characterized the urothelial culture. The cells were then implanted in the scaffold - platelet gel. In a second experiment using aortic porcine acellular matrix were implanted urothelial cells alone and urothelial cells on platelet gel, on the inner wall of the scaffold - aorta, with space for setting bordered by a urethral probe. The complex probe - cells - aorta and probe - cells in platelet gel - aorta, were sealed with suture material and culture were maintained in a humidified 37ºC incubator with 5% CO2 in air for 12 days to subsequent histological analysis of urothelium cell adhesion to the scaffolds. By observation under an optical microscope, we could see the growth of cells in the scaffold platelet gel, from a monolayer in to a three-dimensional structure. In the acellular porcine aortic matrix containing the platelet gel, we could observe a few quantity of urothelial cells adhered. However with the acellular porcine aortic matrix in which was implanted only the urothelial cells, we have obtained adhesion to the wall

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.

Um felino macho, sem raça definida, pesando 3,6 kg com 10 anos de idade foi atendido no Hospital Veterinário “Luiz Quintiliano de Oliveira”, apresentando obstrução uretral com indicação para uretrostomia perineal. Ao exame físico geral, observou-se freqüência cardíaca (FC) de 240 bat.min-1, taquipnéia, temperatura retal (TR) de 38,4oC, mucosas normocoradas, tempo de preenchimento capilar de um segundo e desidratação de aproximadamente 5%. Como medicação pré-anestésica, administrou-se cetamina (6mg.kg-1), midazolam (0,15mg.kg-1) e morfina (0,15mg.kg-1) pela via intramuscular. A veia cefálica foi canulada com cateter 24G para administração de Ringer com Lactato de sódio (10mL.kg-1.h-1) e a indução foi realizada por meio da administração de propofol (4,4mg.kg-1) pela via intravenosa. Seguiu-se a intubação orotraqueal com sonda no 4,0 conectando-se a um circuito sem reinalação de Baraka, sendo a manutenção anestésica efetuada com isofluorano em fluxo diluente de oxigênio a 100%. Em seguida, realizou-se a técnica de anestesia peridural com o paciente em posição esternal e membros pélvicos estendidos cranialmente. Após localização do espaço entre as vértebras L7 e S1, introduziu-se uma agulha 13x4,5 percutaneamente até atingir o espaço peridural, administrando-se morfina (0,1mg.kg-1), fentanil (3mcg.kg-1) e lidocaína a 1% com vasoconstritor (1,8mg.kg-1), perfazendo um volume total de 0,25mL.kg-1. Durante o procedimento anestésico, monitorou-se a FC, freqüência respiratória (f), pressão arterial sistólica (PAS), pressão parcial de dióxido de carbono ao final da expiração (ETCO2), temperatura esofágica (TE), saturação periférica da hemoglobina (SpO2) e plano anestésico. O tempo total de anestesia e cirurgia foi de 65 e 50 minutos, respectivamente. O plano anestésico manteve-se estável, sem a necessidade de resgate analgésico. A SpO2, concentração de isofluorano e TE mantiveram-se em 97±2%, 1,3±0,1% e 36,7±0,4oC, respectivamente. Durante a anestesia, observou-se um momento de hipotensão, provavelmente devido ao bloqueio simpático decorrente da anestesia peridural. Tal evento foi tratado com bolus de solução de Ringer com Lactato de sódio (5mL.kg-1) promovendo o retorno da PAS aos valores de normalidade. A recuperação anestésica do animal foi isenta de complicações inerentes ao procedimento anestésico. O emprego de opióides pela via peridural é recomendado em procedimentos cirúrgicos abdominal, torácico, genito-urinário e ortopédico, principalmente em pacientes de alto risco, obesos e idosos. Em humanos, a associação da morfina e fentanil pela via peridural demonstra analgesia pós-operatória superior à promovida pelo uso isolado da morfina. Conclui-se que na espécie felina, a associação de morfina e fentanil pela via peridural pode ser uma boa alternativa para realização de protocolos de anestesia balanceada para uretrostomia.

Gastroesophageal reflux disease (GERD) is probably one of the most prevalent diseases in the world that also compromises the quality of life of the affected significantly. Its incidence in Brazil is 12%, corresponding to 20 million individuals. OBJECTIVE: To update the GERD management and the new trends on diagnosis and treatment, reviewing the international and Brazilian experience on it. METHOD: The literature review was based on papers published on Medline/Pubmed, SciELO, Lilacs, Embase and Cochrane crossing the following headings: gastroesophageal reflux disease, diagnosis, clinical treatment, surgery, fundoplication. RESULTS: Various factors are involved on GERD physiopathology, the most important being the transient lower esophageal sphincter relaxation. Clinical manifestations are heartburn, regurgitation (typical symptoms), cough, chest pain, asthma, hoarseness and throat clearing (atypical symptoms), which may be followed or not by typical symptoms. GERD patients may present complications such as peptic stenosis, hemorrhage, and Barrett's esophagus, which is the most important predisposing factor to adenocarcinoma. The GERD diagnosis must be based on the anamnesis and the symptoms must be evaluated in terms of duration, intensity, frequency, triggering and relief factors, pattern of evolution and impact on the patient's quality of life. The diagnosis requires confirmation with different exams. The goal of the clinical treatment is to relieve the symptoms and surgical treatment is indicated for patients who require continued drug use, with intolerance to prolonged clinical treatment and with GERD complications. CONCLUSION: GERD is a major digestive health problem and affect 12% of Brazilian people. The anamnesis is fundamental for the diagnosis of GERD, with special analysis of the typical and atypical symptoms (duration, intensity, frequency, triggering and relief factors, evolution and impact on the life quality). High digestive endoscopy and esophageal pHmetry are the most sensitive diagnosctic methods. The clinical treatment is useful in controlling the symptoms; however, the great problem is keeping the patients asymptomatic over time. Surgical treatment is indicated for patients who required continued drug use, intolerant to the drugs and with complicated forms of GERD.
