P-wave indices in Japanese patients with ischemic stroke: Implication of atrial myopathy in subtype of ischemic stroke.

Background: P-wave indices have been not fully studied in subtypes of ischemic stroke. We compared P-wave indices among embolic stroke, lacunar stroke and the control.

Methods: P-wave duration, advanced interatrial block (aIAB) defined as P-wave duration ≥120 ms and biphasic (positive negative) morphology in inferior leads, and P-terminal force in lead V1 (PTFV1) were measured at the time of the first episode of cardioembolic stroke in 81 patients with paroxysmal atrial fibrillation (PAF), and in 64 patients with lacunar stroke, and compared with 100 control subjects.

[A case of postural and kinetic tremor caused by diffuse axonal injury].

We reported a 25-year-old woman with postural and kinetic tremor caused by diffuse axonal injury. The patient demonstrated consciousness disturbance, left oculomotor palsy and tetraparesis because of an automobile accident. T2-weighted and FLAIR MRI showed features of diffuse axonal injury.

[A case of idiopathic portal hypertension (IPH) with hypermanganemia presenting as spastic gait].

A 48-year-old women was admitted to our hospital because of gradually developed spastic gait. She showed spasticity of the lower extremities with mild weakness. Laboratory tests disclosed decreased WBC and platelet counts and mild increases of transaminase and total bilirubin.
