ReviewManagement of cervical spondylotic myelopathy with insights from metabolic imaging of the spinal cord and brain.
Cervical spondylotic myelopathy (CSM) is a potentially debilitating disorder primarily related to spinal cord injury caused by degenerative changes of the spine. As the population continues to age and live longer, it is likely that this disorder will be encountered with increasing frequency. ⋯ CSM is a complex disorder whose incidence is likely to increase in coming years. Prospective, randomized studies are required to help establish the optimal treatment paradigm. Recent advances such as novel neuroimaging techniques and the continued development of neural repair strategies to treat the secondary biological injury associated with this disorder are likely to play key roles in the future management of CSM.

This review briefly discusses the definition and clinical presentation of neuropathic pain and highlights recent advances in the treatment of neuropathic pain. ⋯ Treating neuropathic pain remains a great challenge, and the treatment has to be individualized to the single patient, taking into account side effects, pain type, comorbidities, and drug interactions.

ReviewEmerging genetic therapies to treat Duchenne muscular dystrophy.
Duchenne muscular dystrophy is a progressive muscle degenerative disease caused by dystrophin mutations. The purpose of this review is to highlight two emerging therapies designed to repair the primary genetic defect, called 'exon skipping' and 'nonsense codon suppression'. ⋯ These novel therapies that act to correct the primary genetic defect of dystrophin deficiency are among the first generation of therapies tailored to correct specific mutations in humans. Thus, they represent paradigm forming approaches to personalized medicine with the potential to lead to life changing treatment for those affected by Duchenne muscular dystrophy.

The term 'cerebellar ataxias' encompasses the various cerebellar disorders encountered during daily practice. Patients exhibit a cerebellar syndrome and can also present with pigmentary retinopathy, extrapyramidal movement disorders, pyramidal signs, cortical symptoms (seizures, cognitive impairment/behavioural symptoms), and peripheral neuropathy. The clinical diagnosis of subtypes of ataxias is complicated by the salient overlap of the phenotypes between genetic subtypes. The identification of the causative mutations of many hereditary ataxias and the development of relevant animal models bring hope for effective therapies in neurodegenerative ataxias. ⋯ Recent molecular advances have direct implications for research and daily practice. We provide a framework for the diagnosis of ataxias. For the first time, the therapeutic agents under investigation are targeted to deleterious pathways.

Septic encephalopathy is a frequent complication in severe sepsis, the pathogenesis and mechanisms of which are not fully understood. Here, we review recent advances in our understanding of septic encephalopathy, from molecular mechanisms to behavioral alterations, from diagnostic tools to potential therapeutic agents. ⋯ Septic encephalopathy is a dynamic disease caused by a complex network of systems and pathways going awry. More insights into the pathogenesis of septic encephalopathy are expected to lead to new cellular and molecular targets, which in turn will permit design of specific septic encephalopathy-alleviating drugs and prevent its negative influence on survival.
