ABSTRACT
Abstract Purpose: To investigate the therapeutic potential of human immature dental pulp stem cells in the treatment of chronic spinal cord injury in dogs. Methods: Three dogs of different breeds with chronic SCI were presented as animal clinical cases. Human immature dental pulp stem cells were injected at three points into the spinal cord, and the animals were evaluated by limb function and magnetic resonance imaging (MRI) pre and post-operative. Results: There was significant improvement from the limb function evaluated by Olby Scale, though it was not supported by the imaging data provided by MRI and clinical sign and evaluation. Conclusion: Human dental pulp stem cell therapy presents promising clinical results in dogs with chronic spinal cord injuries, if used in association with physical therapy.

Thirty-four dogs with no deep pain perception due to acute thoracolumbar intervertebral disc disease underwent decompression surgery within 1 week of diagnosis. All dogs underwent hemilaminectomy. Adipose derived mesenchymal stem cells (AD-MSCs) were transplanted into the injured spinal cord parenchyma for the AD-MSCs transplant dogs. Long-term outcome was evaluated at the end of the follow-up period (> 6 months). AD-MSCs combination treatment showed better recovery outcomes compared to decompression surgery alone. These results indicate that this stem cell therapy is a potential therapeutic strategy to overcome the limitations of treatment for spinal cord injury in clinical medicine.

Three dogs presented with refractory immune-mediated thrombocytopenia (IMT). All patients failed to respond to prednisone, which is considered a mainstay of immunosuppressive therapy. Vincristine-loaded platelets (VLPs), which act selectively on mononuclear phagocytes,were introduced. After the VLPs were transfused, two dogs responded quickly withimproved clinical signs while the third dogwith recurrent IMT was euthanized due to its deteriorating condition. This case report describesthe efficacy of VLP therapy in refractory IMT patients.

A dirofilariose é uma zoonose pouco conhecida causada por Dirofilaria spp., nematódeo mais conhecido como verme do coração dos cães (Dirofilaria immitis), parasita do sistema circulatório desses animais, mas que também pode acometer gatos e o ser humano. Sua ocorrência está intimamente ligada à presença de mosquitos vetores (Aedes spp., Anopheles spp., Culex spp.), condições climáticas favoráveis, assim como trânsito entre regiões indenes e endêmicas/epidêmicas. O ser humano pode se infectar com D. immitis (pulmão), Dirofilaria repens (pulmão, subcutâneo) e Dirofilaria tenuis (subcutâneo). A fisiopatologia está intimamente ligada à morte do parasita onde, no cão, pode induzir a obstrução de vasos circulatórios e no ser humano produzir uma lesão nodular com intensa reação inflamatória no parênquima pulmonar com formato de moeda observada nas radiografias. Pode ser diagnosticada pelo exame físico, pela detecção de microfilárias na circulação sangüínea, imunoadsorção enzimático (ELISA), alterações radiográficas, ecocardiografia, ultrassonografia e necropsia. Há riscos no tratamento, sendo a prevenção com a utilização de drogas nos animais o método mais eficaz, principalmente em visitas a áreas endêmicas ou epidêmicas, diminuindo-se, assim, o risco para saúde pública devido à disseminação do parasita.
Dirofilariasis is an unknown zoonosis, caused by Dirofilaria spp, nematodea most known as dog's heartworm (Dirofilaria immitis), which parasites the vascular system of these animals, but infects cats and human beings too. Its occurrence is highly linked to the presence of mosquitoes (Aedes spp., Anopheles spp., Culex spp.), adequate climatic conditions, as well as the transit between infection-free and endemic/epidemic regions. Human beings can be infected by D. immitis (lung), Dirofilaria repens (lung, subcutaneous) and Dirofilaria tenuis (subcutaneous). The physiopathology is highly dependent of the parasite death, inducing the obstruction of the vascular system in dogs and nodular lesions with intense inflammatory reaction in pulmonary parenchyma, like a coin lesion, observed in the radiographs. It can be diagnosed by physical examination, microfilarias detection on the vascular system, enzymatic immunoadsortion (ELISA), radiographic alterations, echocardiography, ultrasonography and necropsy. There are risks on treatment and drug prevention in animals is the most efficient method, mainly in visits to endemic or epidemic areas, decreasing the risk to public health due to the parasite dissemination.

O presente estudo foi desenvolvido com o objetivo de avaliar a técnica de toracoscopia paraxifóide transdiafragmática no diagnóstico e no tratamento do pneumotórax produzido experimentalmente em cães. Para tanto, foram utilizados 11 cães que foram submetidos à produção de pneumotórax grave a partir da aplicação de 10mLkg-1 de ar em cada hemitórax até apresentarem descompensação hemodinâmica. Concomitantemente, foram aferidas a correlação entre a pressão venosa central (PVC) e o volume de ar introduzido (mL kg-1), bem como FC, FR, TPC, SpO2 e coloração das mucosas. O pneumotórax foi tratado pela aplicação de dreno torácico por meio de um trocarte inserido no lado direito (seis animais) ou esquerdo (cinco animais) do apêndice xifóide por meio do diafragma. A introdução em volume igual ou superior a 50ml kg-1hemitórax-1 de ar causou descompensação cardiorrespiratória e elevação da PVC acima de 10cm H2O em todos os pacientes. A técnica proposta permitiu apropriado exame da cavidade torácica e aplicação do dreno com efetiva drenagem, sem a ocorrência de complicações trans e pós-operatórias, condição confirmada pela toracoscopia intercostal aos 15 dias de pós-operatório. Conclui-se que o modelo de produção do pneumotórax e a técnica de colocação de dreno proposta para o manejo dessa doença são adequados para cães.
The aim of the present study was to assess the use of transdiaphragmatic paraxiphoid thoracoscopy for the diagnosis and treatment of experimentally induced pneumothorax in dogs. Severe pneumothorax was induced in 11 dogs by the insufflation of 10mL kg-1of air into each hemithorax until they became hemodynamically unstable. The correlation between central venous pressure (CVP) and the volume of injected air (mL kg-1) was determined, and was considered too heart rate, respiratory frequency, capillary refill time, oxygen saturation and the color of mucous membranes. Pneumothorax was treated with chest tube drainage with the placement of a trocar into the right side (six dogs) or into the left side (five dogs) of the xiphoid appendix through the diaphragm. The introduction of air volume equal to or greater than 50ml kg-1hemitórax-1 caused cardiorespiratory decompensation and increased the CVP to levels higher than 10cmH2O in all patients. Transdiaphragmatic paraxiphoid thoracoscopy allowed for adequate examination of the chest cavity and for effective drainage without any intraoperative and postoperative complications, as confirmed by intercostal thoracoscopy 15 days after surgery. The method for induction of pneumothorax and the chest tube placement technique proposed for its management are appropriate to be used in dogs.

No presente estudo, foram comparados os efeitos da administração intravenosa de três soluções eletrolíticas comerciais sobre o equilíbrio ácido-base em cães desidratados experimentalmente por restrição hídrica e poliúria. Os animais foram aleatoriamente distribuídos em três grupos e tratados com três diferentes soluções eletrolíticas comerciais durante 12 horas: Ringer com lactato de sódio (RL), Ringer simples (RS) e Glicofisiológico (GF). Entre os tratamentos testados, a fluidoterapia intravenosa com solução de Ringer com lactato de sódio (RL) foi o tratamento que apresentou efeito alcalinizante, sinalizado por pequeno aumento nos valores do pH(a), cHCO3(aP), ctCO2(aP) e cBase(a), podendo ser utilizada no tratamento de animais com acidose metabólica de intensidade discreta a moderada. As soluções Ringer simples (RS) e glicofisiológica (GF) determinaram discreta diminuição na concentração de base titulável do sangue arterial (cBase), demonstrando efeito acidificante, o que as tornam uma opção para tratar cães com alcalose metabólica.
Three commercial intravenous electrolyte solutions were compared as for their effects on the blood acid-base status in dogs experimentally dehydrated by withholding water and inducing polyuria. Animals were randomly divided into three groups which were rehydrated with the following commercial electrolyte solutions during 12 hours: Lactate Ringerïs solution (RL), Ringerïs solution (RS) and a normal saline solution (0.9 percent sodium chloride) containing 5 percent dextrose (GF). The RLïs intravenous fluid therapy resulted in an alkalinizing effect demonstrated by a mild increase in arterial blood pH, ctCO2, bicarbonate (cHCO-3), and arterial blood base concentration (cBase) and, thus, can be used in animals exhibiting mild to moderate metabolic acidosis. In contrast, the RS and GF therapies led to a mild decrease in the concentration of arterial blood tritiable base (cBase) inducing an acidifying effect, which make them an option to treat dogs with metabolic alkalosis.

A one-year-old female English Cocker Spaniel dog with idiopathic Horner's Syndrome is described. The specific clinical signs in this specimen were miosis, ptosis, enophthalmos, and prolapsed nictitans for 2 days following sudden onset. According to history taking, ophthalmic, neurological, and radiological examination, the patient was diagnosed with idiopathic Horner's syndrome. Manual acupuncture treatment was applied to the dog on local points two times in 2 days. The local acupoints were ST-4 (Di Chang) and GB-1 (Tong Zi Liao). The day after the initial acupuncture treatment, clinical signs related to idiopathic Horner's syndrome had almost disappeared. The day after the second treatment, specific clinical signs were completely absent. During this period, the dog did not receive any orthodox treatment. Thus, it is suggested that manual acupuncture might be an effective therapy for idiopathic Horner's syndrome.

A twenty-month-old Chihuahua male dog was presented to us suffering with ataxia. Based on the physical examination, X-ray and magnetic resonance imaging (MRI) examinations, we diagnosed the dog with hydrocephalus, Chiari I malformation and syringomyelia. Treatment consisted of internal medical treatment and the placement of a ventriculoperitoneal (VP) shunt. The ventricular dilatation was relieved and the dog improved neurologically; however, the Chiari I malformation and syringomyelia remained after surgically positioning the VP shunt.
