Decompressive craniectomy, interhemispheric hygroma and hydrocephalus: a timeline of events?
Decompressive craniectomy (DC) is a known risk factor for the development of post-traumatic hydrocephalus. The occurrence of subdural hygroma (SH) was also reported in 23-56% of patients after DC and it seemed to precede hydrocephalus in more than 80% of cases. We analyzed the relationship among DC, SH and hydrocephalus. ⋯ Craniectomy close to the midline can predispose patients to the development of hydrocephalus. SH could be generated with the same mechanism, and these three events could be correlated on a timeline.

Posterior reduction and instrumentation with rod-screw construct for atlanto-axial dislocation: a single institutional study with 21 consecutive cases.
Atlanto-axial dislocation is one of the leading causes for occipito-cervical instability. This study aimed for investigating the clinical outcome of rod-screw construct rather than traditional posterior wiring for atlanto-axial dislocation. ⋯ This surgical procedure provided satisfactory reduction of the atlanto-axial joint with significant neurological improvement. Moreover, we successfully avoided complications of posterior wiring.

Does bilateral transverse cerebral venous sinus stenosis exist in patients without increased intracranial pressure?
Transverse cerebral venous sinus stenosis (TSS) is common among patients with idiopathic intracranial hypertension. TSS likely also exists among individuals with normal intracranial pressure (ICP) but the prevalence is unclear. The goal of this study was to identify patients with incidental TSS and normal ICP and describe their characteristics. ⋯ Asymptomatic bilateral TSS exists in patients with ICP≤25 cmH2O, but is likely uncommon. CSF-OP was at the upper limit of normal in our patients, who also had other radiologic signs suggestive (but not specific) of chronically-raised ICP. Findings of bilateral TSS on imaging should prompt funduscopic examination for papilledema.

A pilot study of glioblastoma multiforme in elderly patients: treatments, O-6-methylguanine-DNA methyltransferase (MGMT) methylation status and survival.
Elderly Glioblastoma multiforme (GBM) patients have a worse prognosis and receive variable treatments. MGMT gene promoter methylation is linked with improved survival in GBM. We examined treatments administered and survival including in relation to MGMT methylation status in elderly GBM patients. ⋯ In this small cohort of patients, chemoradiation in suitable elderly GBM patients seemed to afford a survival benefit. MGMT methylation was not associated with an improved survival with temozolamide being the only factor leading to a better survival. Temozolamide use should be considered irrespective of MGMT status in this population with future large prospective studies needed to elucidate this further.

Immediate coma and poor outcome in subarachnoid haemorrhage are independently associated with an aneurysmal origin.
Subarachnoid haemorrhage (SAH) may present with coma and this is known to be associated with aneurysmal origin and blood load. Aneurysmal origin is associated with increased blood load and existing data do not allow us to determine if the association between coma and aneurysmal SAH is wholly due to blood load or if aneurysmal origin has an additional independent effect. The objective of our study is to find if an aneurysmal origin is a predictor of acute onset of coma independent of blood load. ⋯ Immediate coma and poor outcome in SAH are associated with an aneurysmal origin and do not characterize naSAH.
