Neurogenic stunned myocardium (NSM) is a devastating complication of subarachnoid hemorrhage (SAH). The most widely accepted mechanism in the pathogenesis of NSM and takotsubo cardiomyopathy is catecholamine-mediated direct myocardial injury. The aim of this study is to examine if there is any effect of sympathetic overactivity of the stellate ganglions on myocardial tissues, secondary to vagal complex degeneration in SAH-induced NSM. ⋯ NSM and takotsubo cardiomyopathy may be induced by vagal complex degeneration and sympathetic overactivity, which originated from more neurons, including stellate ganglia and more degenerated neuron densities of nodose ganglia.

Hyperactive dysfunction syndrome (HDS) of the cranial nerves, such as trigeminal neuralgia (TN), hemifacial spasm (HFS), and glossopharyngeal neuralgia (GPN), is commonly managed by microsurgical treatment. However, certain patients may present a combination of these syndromes in the neurosurgery department. Here, we aimed to retrospectively assess patients with combined HDS from a single center. ⋯ Combined HDS involves a group of functional disturbance disorders affecting specific cranial nerves, and it may include TN, HFS, and GPN. In addition to gender and incidence of hypertension, age appeared to be a vital indicator for the development of combined HDS, although this finding was inconsistent in previous studies. MVD appears to be a safe and effective treatment for combined HDS, with a high rate of long-term success.

Same-day surgery has been demonstrated to be a safe and cost-effective alternative to traditional inpatient surgery. Several studies have demonstrated no differences in the postoperative complication profile or 30-day hospital readmission rates with outpatient versus inpatient anterior cervical discectomy and fusion (ACDF). However, none of these studies compared the outcomes in elderly patients (aged >65 years) undergoing ACDF. Whether the results from previous studies can be applied to this subgroup pf patients remains unknown. The aim of the present study was to compare the 30-day hospital readmission rates for Medicare patients (aged >65 years) undergoing outpatient versus inpatient ACDF. ⋯ The results from the present study suggest that outpatient ACDF appears to be safe and effective with low complication and readmission rates in a Medicare patient sample.

Results are conflicting as to whether sex has an impact on the outcome of intracerebral hemorrhage (ICH), especially when etiologies differ. In this study, we investigated whether sex differences exist in patients with vascular abnormality-related ICH. ⋯ In our study, female sex was an independent risk factor for poor outcomes in patients with vascular abnormality-related ICH. The factors contributing to this sex difference should be investigated in the future.

The underlying mechanisms of headache in adult moyamoya disease (MMD) are not clear. The aim of this study is to clarify the factors that are associated with headache in adult patients with MMD after superficial temporal artery (STA)-middle cerebral artery (MCA) anastomosis. ⋯ The results of our analyses revealed that aside from ischemia, the postoperative increase rate of the STA may be a candidate reason for headache, especially in adult patients with MMD.
