In recent years, the number of ventriculoatrial (VA) shunt insertions has decreased worldwide, the major cause being the risk of shunt infection. VA shunts remain as an alternative option to ventriculoperitoneal shunts. We describe our 10-year experience with VA shunts by analyzing the incidence of shunt infections and predisposing cofactors. ⋯ In our patient cohort, the infection rate related to VA shunt insertion is low; the only statistically significant risk factor was the number of revisions. If the VA shunt is applied following a standardized protocol, the infection risk does not represent an argument for reluctance towards the VA draining concept.

Several studies have assessed clinical and radiologic outcomes after detethering of the cord for tethered cord syndrome (TCS). However, no data regarding the impact of detethering on the metabolism or electrophysiologic functioning of the cord are available. The aim of this study was to assess the changes in the cerebrospinal fluid (CSF) levels of markers of neuronal injury and alterations in the electrophysiologic functioning of the spinal cord after detethering. ⋯ Surgical detethering led to a reduction in the CSF levels of the markers of anaerobic metabolism and neuronal injury. There was also a reduction in the latencies of the SSEP waves, indicating better electrophysiologic functioning of the cord.

Pituitary apoplexy (PA) often presents with acute headache and neuro-ophthalmic manifestations, including ocular motility dysfunction (OMD) from cranial nerve palsies (CNPs). Our goal was to describe the epidemiology and outcomes of OMD in a large, single-center series of patients with PA. ⋯ OMD from CNPs is common in PA, occurring in one-quarter of patients, and is frequently associated with certain radiologic, endocrinologic, and pathological features. The prognosis is excellent, with 90% of cases of OMD resolving by 1 year after early pituitary surgery.

Management decisions for brainstem arteriovenous malformations (AVMs) are complicated by balancing the risks of treatment and natural progression to hemorrhage. The present study seeks to compare radiosurgery and conservative management outcomes in brainstem AVMs. ⋯ Our results suggest that when patients with brainstem AVM are selected cautiously, radiosurgery may achieve obliteration and symptom relief without increasing subsequent hemorrhage risk.

A retrospective study was conducted to clarify the risk factors of postoperative low back pain (LBP) for lumbar spine disease. ⋯ Type of surgery, operation time, number of operative level, and type of disease were risk factors for the postoperative LBP. Patients underwent PLIF with shorter symptom duration, longer operation time severe LM IMAT, and lumber spondylolisthesis reported more severe LBP before the operation. Patients underwent discectomy with shorter operation times.
