Background: Human immunodeficiency virus (HIV) is a retrovirus mainly infecting immune cells. Central nervous system diseases in HIV-infected patients can be caused by HIV or opportunistic infections. Neurological diseases associated with HIV have diverse manifestations and may occur in early or late stages. This article reports an HIV patient with myelopathy as initial symptom and negative spinal cord magnetic resonance imaging (MRI) and reviews common classifications of HIV-related spinal cord diseases.
Case Presentation: A 50-year-old male presented with weakness in both lower limbs and gait disorders for more than three months. Physical examination and various tests ruled out many possible causes. Given positive HIV and syphilis antibody in serological examination, normal spinal cord MRI and electromyogram, and after excluding other potential diagnoses through comprehensive analysis, the diagnosis of HIV-related myelopathy was established.
Conclusions: Spinal cord lesions caused by HIV infection involve multiple aspects in terms of etiology and mechanism. HIV infection-related vacuolar myelopathy (HIV-VM) is the most common and typical spinal cord lesion. It usually appears at a relatively late stage of HIV infection, but it may also occur in the early stage and even serve as the initial manifestation of newly diagnosed HIV. The diagnosis of HIV myelopathy is usually exclusionary. In imaging, it often shows high T2 signal and spinal cord atrophy on spinal cord MRI, or it may also appear normal.
Clinical Trial: Not applicable.

Background: Awareness of the characteristics of glial fibrillary acidic protein autoantibody (GFAP-IgG) associated myelitis facilitates early diagnosis and treatment. We explored features in GFAP-IgG myelitis and compared them with those in myelitis associated with aquaporin-4 IgG (AQP4-IgG) and myelin oligodendrocyte glycoprotein IgG (MOG-IgG).
Methods: We retrospectively reviewed data from patients with GFAP-IgG myelitis at the First Affiliated Hospital of Zhengzhou University and Henan Children's Hospital from May 2018 to May 2023.

Loss of cervical lordosis (LOCL) is the most common postoperative cervical deformity. This study aimed to identify the predictors of LOCL by investigating the relationship between various factors and LOCL development after surgery for cervical spinal cord tumors. A retrospective analysis was conducted on 51 patients who underwent cervical spinal tumor resection at a single center.

Background: Advanced technologies are becoming increasingly accessible in rehabilitation. Current research suggests technology can increase therapy dosage, provide multisensory feedback, and reduce manual handling for clinicians. While more high-quality evidence regarding the effectiveness of rehabilitation technologies is needed, understanding of how to effectively integrate technology into clinical practice is also limited.

Microglia/macrophages participate in the development of and recovery from experimental autoimmune encephalomyelitis (EAE), and the macrophage M1 (pro-inflammatory)/M2 (anti-inflammatory) phase transition is involved in EAE disease progression. We evaluated the efficacy of crisdesalazine (a novel microsomal prostaglandin E2 synthase-1 inhibitor) in an EAE model, including its immune-regulating potency in lipopolysaccharide-stimulated macrophages, and its neuroprotective effects in a macrophage-neuronal co-culture system. Crisdesalazine significantly alleviated clinical symptoms, inhibited inflammatory cell infiltration and demyelination in the spinal cord, and altered the phase of microglial/macrophage and regulatory T cells.

Inflammation is a driving force of hematopoietic stem cells (HSCs) aging, causing irreversible exhaustion of functional HSCs. However, the underlying mechanism of HSCs erosion by inflammatory insult remains poorly understood. Here, we find that transient LPS exposure primes aged HSCs to undergo accelerated differentiation at the expense of self-renewal, leading to depletion of HSCs.
