Traumatic brain injury (TBI) is major contributor to the global burden of disease, especially in low- and middle- income countries, where most TBIs are traffic-related. Evidence shows that helmets protect against severe TBI. Cambodia continues to have the greatest motorcycle fatality rate in Southeast Asia. We investigated whether the National Motorcycle Helmet Law introduced in January 2016 had an impact on the epidemiology of motorcycle-related TBI in a neurosurgical referral center in Phnom Penh. ⋯ With growing urbanization and motorization, TBI is a significant cause of morbidity and mortality in Cambodia. Two years after helmets became compulsory, most patients with TBI are still unhelmeted. Likely contributing factors are low penalty for noncompliance and inconsistent law enforcement. TBI is a major public health problem warranting further efforts to understand how to improve prevention strategies and advocate for change.

Subclavian steal phenomenon can cause retrograde flow through the ipsilateral vertebral artery as a result of atherosclerosis of the subclavian artery. Clinically this can present as intermittent vertebrobasilar ischemia or claudication of the affected extremity, but rarely it poses a serious risk of neurologic morbidity or mortality. Aneurysm formation at the vertebrobasilar junction is rare but may occur as a sequela of increased flow through 1 vertebral artery, as occurs in subclavian steal syndrome. Here, we present a rare case of subarachnoid hemorrhage from a vertebrobasilar junction aneurysm related to subclavian steal syndrome.

We investigated how augmented reality (AR) can be applied to support transsphenoidal surgery. ⋯ Microscope-based AR is a reliable tool to increase patient safety in complicated transsphenoidal procedures. Intraoperative imaging-based automatic patient registration is recommended.

To investigate the clinical characteristics, treatment, and outcomes of chronic subdural hematomas (CSDH) in young patients. ⋯ Headache is the most common symptom, and AC/V-P shunts are risk factors of CSDH in young patients. AC/V-P shunt-associated CSDH is associated with younger morbidity. Head trauma is a risk factor for AC/V-P shunt-associated CSDH, but is not significance in patients without AC/V-P shunts. Catheter drainage through a burr hole may be the first-choice surgical procedure in treatment of CSDH in young patients, including AC/V-P shunt-associated CSDH.

Transient tumor attack is a rare but well-known phenomenon. Described by Ross in 1983, it demonstrated a transient ischemic attack-like picture in patients with intracranial mass lesions. Usually these attacks were recognized at sites anatomically away from the primary lesion that were not explained by primary mass effect of the lesion. The exact pathophysiology of such transient tumor attacks is postulated to be due to either a vascular steal phenomenon or compression of a vessel or localized prothrombotic state. ⋯ We try to shed some light on the pathophysiology of this unusual phenomenon.
