To elucidate the clinical features, risk factors for contralateral progression, and long-term outcomes of patients with unilateral moyamoya disease (MMD). ⋯ A one-peak pattern in age distribution, lower grade of Suzuki stage, fewer familial cases, and posterior cerebral artery involvement were observed in patients with unilateral MMD. Contralateral abnormalities on initial angiography and infarction at onset were risk factors for contralateral progression in adult and pediatric patients, respectively. Good functional outcomes can be anticipated in the vast majority of surgically treated patients.

Adjunct to embolize the high-flow fistula part of AVM using double lumen balloon catheter.
The purpose of this study is to report our initial experience of Onyx embolization of the high-flow fistula part of arteriovenous malformation (AVM) using a double-lumen balloon catheter. ⋯ The double-lumen Scepter balloon appears to be a safe and convenient device for Onyx embolization of high-flow fistulas.

To determine the relationship between the severity of stenosis graded using both surgeons' visual assessment of spinal stenosis as well as measurement of dural cross-sectional area on magnetic resonance imaging (MRI), with the patient's disability. ⋯ Although surgeons rely on visual assessment of the severity of stenosis while making surgical decisions, we found that objective and subjective imaging parameters to grade severity of stenosis did not consistently indicate the patient's disability level.

To compare the clinical characteristics of cervical spine trauma in patients with ankylosing spondylitis (AS) and cervical ossification of the posterior longitudinal ligament (OPLL) with those of a control group. ⋯ Patients with AS or OPLL who had cervical spine trauma showed different characteristics and outcomes than control patients. Proper surgical treatment led to better outcomes in both patients with AS and patients with OPLL than in control patients. Moreover, it is important to thoroughly examine patients with AS or OPLL after cervical trauma so as not to delay diagnosis.

Corneal Injury from Pre-surgical Chlorhexidine Skin Preparation.
Chlorhexidine skin preparation has been shown to provide highly effective antimicrobial presurgical skin cleansing. However, there is a significant risk of ocular toxicity when it is used in periocular areas. ⋯ If chlorhexidine gluconate must be employed near periocular areas, great care must be exercised to avoid contact with the eyes, and additional protective measures (e.g., absorbent eye pads along with tightly occlusive dressings) must be used whenever possible.
