OBJECTIVE High-frequency oscillations (HFOs, 80-500Hz) from intracranial electroencephalography (EEG) may represent a biomarker of epileptogenicity for epilepsy. We explored the relationship between ictal HFOs and hyperexcitability with a view to improving surgical outcome. METHODS We evaluated 262 patients with refractory epilepsy. Fifteen patients(More)
We aimed to explore the cognitive profiles of subarachnoid haemorrhage patients who returned to the community, along with the associated risk factors. We recruited 40 Chinese patients with spontaneous subarachnoid haemorrhage 7–27 months after the initial presentation. They had all been discharged to their homes or to care homes for the elderly.

Dural transverse sinus arteriovenous fistulas with cortical venous drainage were associated with a high hemorrhagic risk. Dural transverse sinus arteriovenous dural fistulas could be treated by embolization (transarterial or transvenous), surgery or a combination of both. Transvenous packing of the diseased sinus was considered to be a less invasive and(More)
AIM To compare the risk of postoperative haemorrhage with different sizes of brain biopsy needles. PATIENTS AND METHOD A cohort of patients using a 2.5-mm outer diameter side-cutting biopsy needle was compared to a subsequent cohort using a 1.8-mm needle of the same type. All data were collected prospectively. A CT scan was done within 12 h after surgery.(More)
The present study investigated the neuropsychological effects of bilateral deep brain stimulation (DBS) on subthalamic nucleus (STN) in Chinese-Cantonese patients with idiopathic Parkinson’s disease (PD). Twenty-seven patients were prospectively recruited from the Movement Disorder Clinic at the Hong Kong Prince of Wales Hospital. Neuropsychological(More)
OBJECTIVE We assessed the effects of bilateral subthalamic nucleus (STN) deep brain stimulation (DBS) in patients with Parkinson disease at the 1-year and 2-year follow-up evaluations. Unified Parkinson's Disease Rating Scale (UPDRS) motor score at "off" medication ("on" DBS) and quality-of-life assessments (39-item Parkinson's Disease Questionnaire(More)
We report a case of neonatal subdural empyema caused by Mycoplasma hominis. The infant sustained severe birth-related eye injury and subsequently developed multiple subdural empyemata. This report illustrates the clinical presentation of this unusual infection and the crucial role of neurosurgical intervention and specific antimicrobial therapy for its(More)
