BACKGROUND The two most common types of acquired reading disorder resulting from damage to the territory of the dominant posterior cerebral artery are hemianopic and pure alexia. Patients with pronounced hemianopic alexia have a right homonymous hemianopia that encroaches into central or parafoveal vision; they read individual words well, but generate inefficient reading saccades when reading a...

background: chronic daily headache (cdh) has gained little attention in functional neuro-imaging. when no structural abnormality is found in cdh, defining functional correlates between activated brain regions during headache bouts may provide unique insights towards understanding the pathophysiology of this type of headache. methods: we recruited four cdh cases for comprehensive assessments, in...

Anastomoses from extra- to intracranial vessels have been shown in normal patients and, more commonly, in patients with arteriosclerotic occlusive disease, arteriovenous malformation, and postligation of the carotid artery. These channels may be of clinical importance during therapeutic embolization and probably account for two cases of complication, posterior fossa strokes that occurred after ...

Therefore, physicians who perform aesthetic procedures should be aware that late-onset painful nodules are likely to be caused by a bacterial infection such as MRSA, and ident...
