RESUMO
Stem cell-based therapy has been investigated in a number of degenerative and traumatic diseases, including spinal cord injury. In the present study, we investigated the use of autologous mesenchymal stem cells in the functional rehabilitation of a domestic cat presenting a compressive L1-L5 fracture. Bone marrow cells collected by puncture of the iliac crest were cultured to obtain mesenchymal stem cells three weeks before surgery. Hemilaminectomy was performed, followed by injection of the mesenchymal stem cells in the injured area. Clinical evaluation of the animal prior to surgery showed absence of pain, muscular tonus, and panniculi reflexes. Seven days after surgery and cell transplantation the examination revealed a progressive recovery of the panniculus reflexes and of the responses to superficial and deep pain stimuli despite the low proprioceptive and hyperreflexic ataxic hind limbs. Physiotherapy protocols were applied for clinical rehabilitation after surgery. The cat's first steps, three-minute weight-bearing, and intestine and urinary bladder partial reestablishment were observed 75 days post-surgery. Our results indicate the therapeutic potential of mesenchymal stem cells in chronic spinal cord injuries.
RESUMO
A nocardiose do sistema nervoso central tem alcançado importante destaque no diagnóstico diferencial de patologias tumorais nos últimos anos pelo aumento da incidência de pacientes imunodeficiêntes (pacientes submetidos a quimioterapia, transplante de órgäos ou com a síndrome de imunodeficiência adquirida - SIDA. Os autores descrevem o caso de um paciente com SIDA que desenvolveu nocardiose cerebelar na sua forma tumoral. O paciente foi submetido a craniectomia de fossa posterior para diagnóstico e tratamento. Os achados de neuroimagem e patológicos bem como a conduta cirúrgica säo discutidos com base em revisäo da literatura
