Parasympathetic network damage results in facial nerve damage, sublingual ganglion degeneration, sublingual gland dysfunction, and dry mouth. In this study, subarachnoid hemorrhage (SAH) was considered to be the cause of dry mouth. ⋯ Clinical findings in infection and diseases such as Sjögren syndrome, aseptic meningitis, and SAH are similar. However, until now, SAH has not been demonstrated experimentally to cause dry mouth. Discovering that SAH might cause dry mouth might prevent unnecessary use of antibiotics and decrease morbidity due to the wrong or late diagnosis.

The current study aimed to assess the risk factors and preventive measures for valve inversion after lumboperitoneal shunt (LPS) construction. ⋯ The distance between the valve and spinous process was found to be significantly correlated with valve reversal. However, the condition can be prevented by fixing the tube at the nuchal ligament.

Renal cell carcinoma with metastases to the spine (RCCMS) requires a multidisciplinary approach. We reviewed our institutional experience with RCCMS patients undergoing spinal surgery in order to identify factors that may affect clinical outcomes, survival, and complications. ⋯ Median postoperative survival of patients with RCCMS was 8 (0.3 - 92) months. Higher Tokuhashi score and ASIA E score at follow-up correlated with improved overall survival. Complication rate was 16%. Spinal surgery in RCCMS is indicated for the preservation of function and prevention of neurologic deterioration. Multimodality therapy with improved chemotherapy and stereotactic spinal radiation is expected to impact quality and length of survival positively.

To compare clinical and imaging outcomes after cervical disc replacement (CDR) in patients with different Hounsfield units (HU). ⋯ The HU value has a large variation range among the patients with T-score ≥ -2.5. We found significantly increased rates of implant subsidence, loss of ISH, and adjacent segment degeneration in patients with lower HU value undergoing CDR. However, these radiographic complications did not predispose patients with lower HU value to worse clinical outcomes. Routine application of HU combined with dual-energy X-ray absorptiometry measurement to evaluate bone quality may help to screen the optimal candidates for CDR and reduce the implant-related complications.

Giant aneurysms of the intracranial vertebral artery and posterior inferior cerebellar artery are challenging to treat as they often necessitate direct sacrifice of the diseased segment, which is thought to carry high morbidity due to brainstem and cerebellar stroke. Here, we report images of twin giant aneurysms of the left posterior inferior cerebellar artery at the brainstem and cerebellopontine angle region in a young child.
