A dissociation between the ability to recognize misoriented objects and to determine their orientation has been reported in a small number of patients with vascular lesions. In this article, we describe a 57-year-old man with probable Alzheimer' s disease who shows the same dissociation. Neuroimaging findings indicated marked hypometabolism in the posterior cortical regions, particularly the po...

Sciatic neuropathy is the second most common neuropathy of the lower extremity and a common cause of foot drop. This article reviews the anatomy, clinical features, pathophysiology, and electrodiagnostic assessment of sciatic neuropathies. There are multiple potential sites of pathology, determined in part by the mechanism of insult, including trauma, compression, masses, inflammation, and vasc...

Certain diets essentially identical with those previously reported as causing an elevation of the blood pressure of rats have failed to produce any elevation. Examination of micro sections from the kidneys of these rats, with the aid of special stains, has failed to demonstrate any vascular lesions similar to those previously described by Calder. Evidence of tubular atrophy was present to a min...

An increasing number of studies suggest a vascular contribution to Alzheimer's disease (AD). One major question these findings raise is whether vascular disease enhances the formation of AD-like lesions, or whether vascular disease just adds to clinical severity. We examined this question in a fully characterized autopsy sample based on the Honolulu Asia Aging Study. We found that AD markers of...

Cutaneous congenital vascular lesions are the most common pediatric birthmarks. These vascular lesions are abnormalities of blood vessels, both arterial and venous, that appear at birth or in infancy [1]. They are classically divided into hemangiomas and vascular malformations; hemangiomas tend to spontaneously involute while vascular malformations tend to persist [2,3]. Congenital lesions are ...

Introduction: Cutaneous leishmaniasis (CL) is a parasitic skin infection which can be debilitating. This study was performed to determine the vascular changes in the histopathology of CL. Methods: Thirty-seven patients with CL were included in a prospective study. A 4 mm punch biopsy was obtained from the border of the lesion. After histopathologic processing and H&E staining, it was reviewed ...

Vascular malformations of the muscle are rare non-proliferative vascular lesions, and few case reports have described intramuscular in upper extremities. may produce musculoskeletal deformities due to contracture. Symptomatic commonly treated with surgery interventional management. We report a malformation that could not be completely resected. It caused adduction contracture thumb hand. Sclero...

large vessel involvement is one of the hallmarks of behcet’s disease (bd) but its prevalence varies widely due to ethnic variation or environmental factors. the aim of this study is to find the characteristics of vasculo-behcet (vb) in iran. in a cohort of 4769 patients with bd, those with vascular involvement were selected. different manifestations of disease were compared with the remaining g...

OBJECTIVE The aim of this work was to verify the usefulness and efficacy of treating superficial vascular lesions of the face using rhodamine intense pulsed light (r-IPL). SUBJECTS AND METHODS Fifty patients suffering from telangiectasias of the face were enrolled and subsequently treated 4 times (every 20 days) with a new intensified r-IPL system optimized at the same wavelength as the dye l...
