Cerebral microbleeds (CMBs) have been established as an independent predictor of cerebral bleeding. There are contradictory data regarding the potential association of CMB burden with the risk of symptomatic intracerebral hemorrhage (sICH) in patients with acute ischemic stroke (AIS) treated with intravenous thrombolysis (IVT). ⋯ Presence of CMB and high CMB burdens on pretreatment MRI were independently associated with sICH in patients with AIS treated with IVT. High CMB burden may be included in individual risk stratification scores predicting sICH risk following IVT for AIS.

Longitudinal Assessment of Small Fiber Neuropathy: Evidence of a Non-Length-Dependent Distal Axonopathy.
Few data are available on the natural history of small fiber neuropathy (SNF). Peripheral neuropathy typically follows a length-dependent pattern, leading us to hypothesize that patients with SFN would lose intraepidermal nerve fibers at the distal leg more quickly than at more proximal thigh sites. ⋯ Similar rates of IENFD decrease irrespective of cause were observed. Epidermal nerve fibers were lost at similar rates in proximal and distal sites, suggesting that SFN is a non-length-dependent terminal axonopathy.
