Acute progression of cerebral amyloid angiopathy-related inflammation diagnosed by biopsy in an elderly patient: A case report.

Background: Cerebral amyloid angiopathy-related inflammation (CAA-I) presents with slowly progressive nonspecific neurological symptoms, such as headache, cognitive function disorder, and seizures. Pathologically, the deposition of amyloid-β proteins at the cortical vascular wall is a characteristic and definitive finding. Differential diagnoses include infectious encephalitis, neurosarcoidosis, primary central nervous system lymphoma, and glioma.

Peritonitis is still an important factor for withdrawal from peritoneal dialysis therapy in the Tokai area of Japan.

Background: In Japan, the population of patients on peritoneal dialysis (PD) is <4% of the total number of patients with end-stage renal disease. Few systemic analyses have examined why the number of PD patients has not increased in Japan. We organized a registry to analyze PD patients and retrospectively investigated 561 PD patients (about 5% of all Japanese PD patients) from 13 hospitals in the Tokai area for 3 years from 2005.

Severe coronary stenosis is an important factor for induction and lengthy persistence of ventricular arrhythmias during and after hemodialysis.

Background: Ventricular arrhythmias have been shown to be the major cause of sudden cardiac death in hemodialysis (HD) patients. We investigated whether angiographic coronary stenosis was responsible for the induction of ventricular arrhythmias in HD patients.

Methods: HD patients (n = 150) showing ischemic signs in exercise electrocardiography or echocardiography were divided into 2 groups: the stenotic group (n = 61), with significant coronary stenosis (> or =75% in diameter), and the nonstenotic group (n = 89), without significant coronary stenosis on coronary angiography.

Non-dipping is a potent predictor of cardiovascular mortality and is associated with autonomic dysfunction in haemodialysis patients.

Background: Lack of nocturnal blood pressure (BP) fall (non-dipping) is common among haemodialysis (HD) patients, but much less is known regarding its association with cardiovascular (CV) disease morbidity and mortality.

Methods: Eighty HD patients initially underwent 24 h ambulatory BP monitoring (ABPM), and then they were defined as either 'dippers' (n=24, nocturnal BP fall > or = 10%) or 'non-dippers' (n=56, fall <10%). Coronary angiography was performed in the patients who had signs and/or symptoms of coronary artery disease (CAD).
