Many factors affect spinal alignment in adult spinal deformity with sagittal imbalance. However, although the importance of the paravertebral muscle and ligamentum complex in proper spinal alignment is well recognized, little information is available regarding the role of the paravertebral muscles in maintaining sagittal spinal alignment. ⋯ Degeneration of the paravertebral muscle is a risk factor for degenerative adult spinal deformity with sagittal imbalance but not for sarcopenia. Thus, spinal sagittal imbalance is affected by isolated paravertebral muscle degeneration rather than by systemic muscle degeneration.

Tumor necrosis factor receptor-related factor 3 (TRAF3) interacting protein 3 (TRAF3IP3) is involved in the development of immune tissues and the immune response of the body. Downregulated expression of TRAF3IP3 in malignant melanoma can inhibit tumor growth. The role of TRAF3IP3 in glioma is unknown. ⋯ TRAF3IP3 play an important role in the occurrence and development of glioma and may be a potential biomarker for the prognosis of glioma.

The parahippocampal gyrus is understood to have a role in high cognitive functions including memory encoding and retrieval and visuospatial processing. A detailed understanding of the exact location and nature of associated white tracts could significantly improve postoperative morbidity related to declining capacity. Through diffusion tensor imaging-based fiber tracking validated by gross anatomic dissection as ground truth, we have characterized these connections based on relationships to other well-known structures. ⋯ The parahippocampal gyrus is an important center for memory processing. Subtle differences in executive functioning following surgery for limbic tumors may be better understood in the context of the fiber-bundle anatomy highlighted by this study.

The acute-stage intraoperative findings of the spinal dural laceration in patients with traumatic cerebrospinal fluid (CSF) leakage have not been clearly revealed so far. Herein, we report an interesting case of traumatic CSF leakage in a patient who underwent acute-stage direct closure for a dural laceration similar to a stab at the C1/2 level. Because a 41-year-old man strongly twisted his neck, he had a typical orthostatic headache. ⋯ Direct surgical closure was performed 13 days after the onset of symptoms, and dural laceration with sharp edges was detected on the right side at the C1/2 level. The laceration was sutured and coated with dural sealant. Finally, the patient's orthostatic headache was relieved completely after the operation.
