Chronic Inflammatory Demyelinating Polyradiculoneuropathy Associated with Membranous Glomerulonephritis and Tendinitis

Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an immune-mediated progressive or relapsing demyelinating peripheral neuropathy. Other autoimmune diseases may be associated with CIDP. A 38-year-old man developed CIDP, which was subsequently associated with membranous glomerulonephritis (MGN) and tendinitis. He was treated with intravenous immunoglobulin, rituximab, and prednisone, which resulted in improvement of the clinical symptoms. This is a case report of CIDP associated with MGN and tendinitis.

The Impact of Hemodialysis and Arteriovenous Access Flow on Extracranial Hemodynamic Changes in End-Stage Renal Disease Patients

In this study, we characterized cerebral blood flow changes by assessment of blood flow parameters in neck arteries using carotid duplex ultrasonography and predictive factors for these hemodynamic changes. Hemodynamic variables were measured before and during hemodialysis in 81 patients with an arteriovenous access in their arm. Hemodialysis produced significant lowering in peak systolic velocity and flow volume of neck arteries and calculated total cerebral blood flow (1,221.9 ± 344.9 [before hemodialysis] vs. 1,085.8 ± 319.2 [during hemodialysis], P < 0.001). Effects were greater in vessels on the same side as the arteriovenous access and these changes were influenced by arteriovenous access flow during hemodialysis, both in the CCA (r = -0.277, P = 0.015) and the VA (r = -0.239, P = 0.034). The change of total cerebral blood flow during hemodialysis was independently related with age, presence of diabetes, and systemic blood pressure.

A Case of Unilateral Internal Carotid Artery Stenosis Presenting with Chronic Isolated Dizziness / 대한평형의학회지

It is customary that the dizziness related to cerebral perfusion might be caused by insufficient posterior circulation. The occurrence and nature of dizziness originating from anterior circulation has not been well-known. Here, we report a chronic dizzy woman presenting with severe internal carotid artery stenosis, which improved after carotid artery stenting.
