Beyond collaterals: brain frailty additionally improves prediction of clinical outcome in acute ischemic stroke.

Objectives: We aimed to investigate the additional significance of cerebral small vessel disease (SVD) beyond collaterals in determining the clinical outcome after acute ischemic stroke (AIS).

Methods: We retrospectively reviewed large vessel-involved stroke patients who had baseline CTA within 24 h after symptom onset and had an MRI scan 5 days after admission from October 1, 2018, to October 31, 2021. Collaterals and SVD markers (including atrophy, leukoaraiosis, lacunes, and perivascular space) were graded on CT angiography and MR images, respectively.

Treatment of displaced radial head fractures by internal fixation with absorbable pins.

Objective: To study the effect of internal fixation with absorbable pins on treatment of displaced radial head fractures.

Methods: From May 1999 to May 2004, 16 patients with displaced radial head fractures (Mason types II and III) were treated with internal fixation by absorbable pins. The duration of follow-up averaged 22.
