To determine the association between patient-reported depressive symptoms and patient satisfaction following minimally invasive lumbar decompression. ⋯ Independent effect of depression at long-term follow-up was significant. This highlights the importance of understanding the interaction between physical and mental health outcomes to optimize patients' perceptions of surgical outcomes.

Brain 123I-iomazenil single-photon emission computed tomography (SPECT) can assess the distribution of the binding potential of central benzodiazepine receptors in the cerebral cortex. This binding potential may reflect neuronal function in viable tissues. The present prospective study using brain 123I-iomazenil SPECT aimed to determine whether improvements in cognitive function after indirect revascularization surgery alone are associated with postoperative recovery in neurotransmitter receptor function in the affected cerebral hemisphere among adult patients with moyamoya disease accompanied by ischemic presentation due to misery perfusion. ⋯ Improvements in cognitive function after indirect revascularization surgery alone are associated with postoperative recovery in the binding potential of central benzodiazepine receptors in the affected cerebral hemisphere in adult patients with moyamoya disease accompanied by ischemic presentation due to misery perfusion.

To identify the best protective interventions against shunt infection and, hence, to find an appropriate protocol assumed to be associated with reduction of infection rates. ⋯ Shunt infection is a significant complication that occurs early during the first 2 months after surgery. According to the study findings, an appropriate protocol against shunt infection is assumed to be composed of double-gloving, device and wound irrigation using vancomycin solution, and the use of incision adhesive drapes. Reduced operative time had a beneficial effect against shunt infection, although it was of marginal significance in the current study.

Data on the outcomes of CyberKnife-based hypofractionated stereotactic radiosurgery (hSRS) for intracranial and extracranial nonvestibular schwannomas (nVSs) are not sufficient. ⋯ We summarized the treatment outcomes of hSRS for nVSs. Although all patients achieved radiological tumor control, the risk of either transient or permanent ARE was high. Therefore, it is necessary to monitor patients for clinical deterioration due to AREs.

Spontaneous acute subdural hematoma (sASDH) is a rare neurosurgical condition, with the literature mainly consisting of case reports. In the present study, we compared sASDH with traumatic ASDH (tASDH) to determine the differences in presentation, radiological features, and outcomes in a population-based setting. ⋯ In the present population-based study of surgically evacuated ASDH cases, 9% were spontaneous without previous trauma. The outcomes (GOS scores) were significantly more favorable for those with sASDH than for those with tASDH. In one half of the patients with sASDH, arterial bleeding was noted perioperatively, although the preoperative radiological examinations revealed no abnormalities for most patients. However, the lack of sufficient examinations such as computed tomography angiography made it difficult to establish the most common etiology of bleeding in those with sASDH. Further research is warranted to determine the reference standard method for the investigation of sASDH.
