The literature is lacking data concerning the prognosis in cats suffering from naturally occurring acute onset of thoracolumbar (TL) spinal cord injury that are undergoing rehabilitation therapy. Therefore, we investigated the effect of physical rehabilitation in cats suffering from naturally occurring TL spinal cord injury. The medical records of 36 cats with acute onset of TL spinal cord injury that were selected for rehabilitation treatment were reviewed. Twenty-nine cats underwent an intensive physical rehabilitation protocol in the clinic (group 1), whereas the owners of seven cats declined physical rehabilitation (group 2). In group 1, seven cats had pelvic limb deep pain perception (DPP), which was significantly associated with the functional recovery of voluntary ambulatory status (p = 0.010) and voluntary micturition (p < 0.001). Spinal walking was achieved in 10/22 (45%) of the cats without DPP, and none regained voluntary micturition. In group 2, no cats regained ambulatory status or voluntary micturition, although pelvic limb DPP was present in three patients. Treatment with a clinic-based rehabilitation program and the presence of a crossed extensor reflex were significantly associated with a higher possibility of regaining functional ambulatory status (p < 0.010), but there was no difference in the recovery of voluntary micturition between the groups. Thus, cats with severe, naturally occurring, acute onset of TL spinal cord injury may benefit from physical rehabilitation. In the case of the loss of DPP, the acquisition of spinal walking is possible, despite the high possibility of a persistent neurologically dysfunctional bladder.

Three cases of the malformation of the cortical development are described: a mixed breed dog and a Border Collie pup with a focal and diffuse cortical dysplasia, respectively, and a kitten with lissencephaly. All cases presented with intractable epilepsy and were euthanized, due to the cluster of epileptic seizures. The gross examination at necropsy revealed the morphologic alteration of the telencephalic region in two cases. Histopathologically, a disorganization of the cortical lamination with the presence of megalic neurons, was found in the focal cortical dysplasia case. An altered organization of the white and gray matter, with a loss of the normal neuronal distribution and altered neurons, characterized the diffuse cortical dysplasia case. In the lissencephalic cat, there was no recognizable organization of the brain with areas of neuroglial tissue forming nodules in the leptomeningeal space. We strongly support the hypothesis that, as in humans, as well as in the veterinary patients, malformations of the cortical development could be the cause of refractory epilepsy.

Meningoencephalomyelitis of unknown origin (MUO) is an inflammatory central nervous system disease affecting the meninges, brain, and spinal cord. Interest in this condition has been growing rapidly over the last decade, but information on the pathophysiology and evolution of the disease is still lacking. This study aimed to assess and evaluate the clinical findings, magnetic resonance imaging (MRI) features, and survival time in affected French Bulldogs (FBs). A total of 27 client-owned FBs met the inclusion criteria. The highest percentage of animals were affected by acute blindness and cervical pain, representing 25.9% (n = 7) each. Via MRI, 44.4% of FBs showed signs of perilesional parenchymal brain edema. Midline shift was observed in 11.1% of dogs, and 7.4% displayed foramen magnum cerebellar herniation. The cerebrospinal fluid examination was considered normal in 34.8% of dogs. Five (18.5%) dogs died during the treatment. Close to two-thirds (63.0%) were still alive during the study data collection (median survival time, 775 days), displaying an overall good survival time. The presence of epileptic seizures, midline shift, and relapse of clinical signs were factors associated with higher mortality rate (p < 0.05) and might be prognostic factors for worse survival in French Bulldogs with MUO.

Background: literature is lacking data concerning the prognosis in cat suffering from acute thoracolumbar spinal cord lesions on field condition either with or without physiotherapy treatment. We investigated the role of intensive physical rehabilitation training in cats suffering from acute thoracolumbar (TL) spinal cord injury and compared their outcome to the presence/absence of pelvic limb pain perception (PP) under field conditions. A further aim was the evaluation of the outcome of cats under intensive physiotherapy when compared to a control group.Methods: Retrospective study. The medical records of 29 feline patients with acute TL spinal cord injury, with and without PP, selected for intensive rehabilitation treatment were reviewed. Those cats that satisfied the same criteria, but performed at home physiotherapy exercises with the owner, were enrolled as control group.Results: 7 cats had pelvic limb PP, which resulted significantly associated with functional recovery of voluntary locomotion (p=0.01) and voluntary micturition (p= 0.00006). Twenty-two cats (76%) had the absence of pelvic limb PP and the acquisition of spinal walking (SW) was achieved in ten cats (45%). None of these patients regained a voluntary micturition at the end of the treatment. The presence of the crossed extensor reflex on admission was significantly associated with the acquisition of SW (p= 0.008). At 15 days, improvement in assisted walking/UWTM was found to be significantly associated with higher possibility to achieve SW at the end of the treatment (p=0.04). The control group included seven cats. None of the cats had regained voluntary micturition or ambulatory condition. Comparing to the control group, the intensive rehabilitation program was significantly associated with a higher possibility to regain functional locomotion (p= 0.005). Recovery of voluntary micturition did not show significant differences among the control group and the cats that underwent physical therapy.Conclusions: cats with severe acute TL lesion recovery can benefit from physiotherapy and, also in case of loss of PP, the acquisition of SW is possible under field condition.
