Lupus anticoagulants and anticardiolipin antibodies are antiphospholipid antibodies (APLAb) with related antigenic specificities and are newly recognized markers for an increased risk of thrombosis. We studied 48 patients who presented with cerebral or visual dysfunction associated with APLAb to help clarify the diagnostic, clinical, laboratory, radiologic, and pathologic features in these patients. Most patients presented with transient cerebral ischemia or cerebral infarction. Recurrent and stereotypic events were frequent. Visual disturbances resulted from amaurosis fugax, retinal arterial or venous occlusion, occipital ischemia, diplopia, and migraine-like disturbances. Three patients presented with severe atypical classic migraine. Recurrent infarcts of brain and eye were significantly associated with the presence of cigarette smoking, hyperlipidemia, and a positive antinuclear antibody. During 44.4 patient-years of prospective follow-up, the combined stroke and systemic thrombotic event rate was 0.27 events per patient-year and was 0.54 events per patient-year if TIA and death were included. Forty (83%) of the patients did not have systemic lupus erythematosus (SLE). Thrombocytopenia was present in 15 (31%) and a false-positive VDRL in 11 (23%) of the patients. Cerebral angiography was normal or revealed large-vessel occlusion or stenosis without changes suggestive of vasculitis. Patients with only transient dysfunction generally had normal radiologic studies, including angiography. Organs and arterial vessels studied pathologically revealed thrombotic occlusive disease without vasculitis. APLAb are strongly associated with an immune-mediated thrombotic tendency, generally in the absence of SLE. Other stroke risk factors may add to the risk of recurrent ischemic events in patients with APLAb.

A long-term hemodialysis patient with a giant intracranial vascular channel, which has been called a giant serpentine aneurysm, is presented. A 50-year-old man with an eight-year history of hemodialysis treatment was admitted because of headache, nausea and double vision. Computed tomographic scans and nuclear magnetic resonance revealed intracranial abnormal shadow. The left vertebral arteriography showed that the distal portion of the left vertebral artery was dilated to 17 mm in diameter. The basilar artery showed a large tortuous vascular channel and globular aneurysms over 25 mm in diameter. This giant serpentine aneurysm is a rather rare disease. To our knowledge, it has not been reported as a complication in a hemodialysis patient, although fourteen cases have been reported in the literature. In our case, several conditions such as long-term hypertension, hyperlipidemia, hypercalcemia, atherosclerosis and abnormal blood flow due to arteriovenous fistula for hemodialysis treatment might be considered to play a role in the formation of the giant serpentine aneurysms.

Ocular signs and symptoms provide clinical clues to many of the more common metabolic and nutritional disorders seen in older adults. Diabetes mellitus can affect all parts of the eye and orbit. Complications include refractive visual loss, macular edema, retinopathy, increased risk of fungal infection, and diplopia. In patients with gout, urate crystals may precipitate in the eye and cause conjunctivitis, uveitis, or scleritis. Other problems are seen with Wilson's disease, hyperlipidemia, and albinism. Nutritional disorders usually arise from malabsorption, gastrointestinal surgery, and alcohol abuse. Deficiencies in vitamins A, B1 (thiamine), B12, and C may be manifest in the eye.

A 79-year-old woman presented to the emergency room with a chief complaint of headache of 1 month's duration. Her medical history consisted of hypertension, congestive heart failure, anemia, chronic kidney disease, and hyperlipidemia. She reported the headache as waxing and waning, and occurring bilaterally in the frontal and occipital regions. On examination, she was found to have mild right-sided ptosis and possible early right-sided papilledema. She was also found to have bilateral shoulder tenderness and scalp tenderness. She denied double vision, vision changes, or jaw claudication.
