1/252. Severe panarteritis associated with drug abuse.A case of panarteritis with purpura fulminans, mononeuritis multiplex, gastrointestinal manifestation and presumably cardiac involvement in a previously healthy 22-year-old man with a history of drug abuse including cocaine, cannabinoids and methamphetamines is described. Histopathological examination of the gut led to the diagnosis of panarteritis without immune deposits. Antineutrophil antibodies were negative. Besides the drugs, no other possible cause of vasculitis was found. The patient recovered completely after 1 year. Drug abuse is a thus possible cause of severe extracerebral disabling vasculitis.- - - - - - - - - - ranking = 1keywords = arteritis (Clic here for more details about this article) |
2/252. Myocardial infarction in patients with systemic lupus erythematosus with normal findings from coronary arteriography and without coronary vasculitis--case reports.The authors present the cases of two young patients, a man and a woman, who presented with myocardial infarction, in the absence of ischemic heart disease or stenosis of the coronary arteries. The woman was known to have systemic lupus erythematosus (SLE) for the past 3 years (the immunoglobulin m [IgM] anticardiolipins antibodies were positive), without a history of coronary risk factors. Suddenly she presented with acute chest pain on rest that lasted 4 hours and culminated in anterior wall myocardial infarction. She was admitted to the coronary care unit, where no thrombolysis was given. She did not have echocardiographic evidence of Libman-Sacks endocarditis, but myocardial infarction was evident at the electrocardiogram (ECG). The young man had SLE (the IgM anticardiolipins were absent, but he was positive for lupus anticoagulant antibodies), he was hyperlipidemic, was a moderate smoker and moderately obese, and had no history of ischemic heart disease. He suddenly presented with an acute myocardial infarction documented by ECG, enzymes, and gammagraphy. In both patients, coronary angiography findings were normal and myocardial biopsy did not show evidence of arteritis. The relevance of these cases is the rare association of ischemic heart disease in SLE, with normal coronary arteries and without evidence of arteritis or verrucous endocarditis.- - - - - - - - - - ranking = 0.33333333333333keywords = arteritis (Clic here for more details about this article) |
3/252. Systemic granulomatous arteritis associated with Epstein-Barr virus infection.A 61-year-old woman initially presented with symptoms and findings reminiscent of infectious mononucleosis, and her illness then took a rapidly fatal course. autopsy revealed widespread granulomatous arteritis, with multinucleated giant cells but without eosinophils and fibrinoid necrosis, affecting small arteries and arterioles and infiltration of haemophagocytic histiocytes into many organs. in situ hybridization with Epstein-Barr virus (EBV)-specific oligonucleotide probes showed positive signals in the infiltrating immune cells and epithelial and endothelial cells of the affected organs. EBV-associated haemophagocytic syndrome (EBV-AHS) with systemic granulomatous arteritis was diagnosed. From the immunophenotypes of the infiltrating immune cells, a possible role of CD4 T-cells in the pathogenesis of this haemophagocytic syndrome and granulomatous vasculitis was suggested.- - - - - - - - - - ranking = 1keywords = arteritis (Clic here for more details about this article) |
4/252. Isolated pontine infarction due to rhinocerebral mucormycosis.We report a patient with rhinocerebral mucormycosis whose initial central nervous system involvement was isolated pontine infarction due to basilar arteritis caused by the fungus. The patient was diagnosed and followed by MRI and CT and basilar arteritis was demonstrated well on MRI studies. Involvement of the skull base was shown on CT in the later stage of the disease. The unusual initial presentation of the infection is discussed.- - - - - - - - - - ranking = 0.33333333333333keywords = arteritis (Clic here for more details about this article) |
5/252. Staphylococcal coronary arteritis as a complication of septicemia.We describe a case of staphylococcal coronary arteritis in the setting of sepsis due to arteriovenous fistula and dialysis catheter infection. The left circumflex coronary artery was the only vessel involved. The patient was a 77-year-old, insulin-dependent diabetic man with chronic renal failure. The immunosuppressed state in diabetes with subsequent septicemia may have facilitated a large number of bacteria to lodge in the atheromatous plaque of the coronary artery. We briefly review previously reported cases and suggest that bacterial arteritis may be an underrecognized cause of acute coronary occlusion.- - - - - - - - - - ranking = 1keywords = arteritis (Clic here for more details about this article) |
6/252. Unusual complications in an inflammatory abdominal aortic aneurysm.An unusual case of an inflammatory abdominal aortic aneurysm (IAAA) associated with coronary aneurysms and pathological fracture of the adjacent lumbar vertebrae. The associated coronary lesions in cases of IAAA are usually occlusions. In the present case, it was concluded that a possible cause of the coronary aneurysm was coronary arteritis and the etiology of the pathological fracture of the lumbar vertebrae was occlusion of the lumbar penetrating arteries due to vasculitis resulting in aseptic necrosis. Inflammatory AAA can be associated with aneurysms in addition to occlusive disease in systemic arteries. The preoperative evaluation of systemic arterial lesions and the function of systemic organs is essential.- - - - - - - - - - ranking = 0.16666672920829keywords = arteritis, essential (Clic here for more details about this article) |
7/252. Subclavian arteritis and pseudoaneurysm formation secondary to stent infection.Technically uncomplicated percutaneous angioplasty and stent placement of a left subclavian artery stenosis was performed in a 56-year-old man for treatment of subclavian steal syndrome and vertebrobasilar insufficiency. Six days later the patient was readmitted with staphylococcus aureus bacteremia and stigmata of septic emboli isolated to the ipsilateral hand. Nine days later he had computed tomography (CT) evidence of a contrast-enhancing phlegmon surrounding the stent. Despite clinical improvement and resolution of bacteremia on intravenous antibiotic therapy, the phlegmon progressed, and at day 21 a pseudoaneurysm was angiographically confirmed. The patient underwent surgical removal of the stented arterial segment and successful autogenous arterial reconstruction. The possible contributory factors leading to stent infection were prolonged right femoral artery access and an infected left arm venous access. Although the role of prophylactic antibiotics remains to be defined, it may be important in cases where the vascular access sheath remains in place for a prolonged period of time.- - - - - - - - - - ranking = 0.66666666666667keywords = arteritis (Clic here for more details about this article) |
8/252. In utero development of hypertensive necrotizing pulmonary arterial lesions: report of a case associated with premature closure of the ductus arteriosus and pulmonary hypoplasia.Premature closure of the ductus arteriosus (PCDA) is an uncommon defect in which pulmonary hypertension (PH) has been documented by echocardiography in patients and by direct measurement after experimental PCDA in animals. The pulmonary vascular histology in human cases has received little attention but in the few recorded observations the vessels were either normal or showed increased muscularity. We report the case of a 31 week hydropic female stillborn monozygotic twin in whom postmortem examination disclosed PCDA and hypoplasia of the lungs. Atypical plexiform lesions with necrotizing pulmonary arteritis were present. These lesions represent vascular consequences of severe pulmonary hypertension produced by greatly enhanced blood flow through a restricted vascular bed resulting from the combined effects of these two abnormalities. The findings in this case of PCDA with presumed severe PH indicate that severe pulmonary vascular changes can develop in utero and that the interval of time needed for development of such chances in secondary PH is relatively short.- - - - - - - - - - ranking = 0.16680674263282keywords = arteritis, necrotizing (Clic here for more details about this article) |
9/252. Cerebral arteritis following methylphenidate use.stroke is a well-documented complication of amphetamine abuse. methylphenidate, chemically and pharmacologically similar to amphetamines, is widely used in the treatment of attention deficit disorder in children. The possibility of vasculitis connected to methylphenidate should not be surprising. A case is reported of stroke associated with ingestion of methylphenidate in an 8-year-old boy. family history was negative and other causes of vasculitis were excluded. We draw your attention to the risk of using methylphenidate for a long period of time.- - - - - - - - - - ranking = 0.66666666666667keywords = arteritis (Clic here for more details about this article) |
10/252. central nervous system and renal vasculitis associated with primary varicella infection in a child.A 7-year-old girl with primary varicella presented with encephalopathy and focal neurologic deficits 10 days after her first skin lesions appeared. She was discovered to have bilateral wedge-shaped renal infarctions, and ischemic lesions in the conus medullaris, cerebral cortex, and deep gray matter consistent with a medium and large vessel arteritis on magnetic resonance imaging. This complication has never before been reported in an immunocompetent child with primary varicella infection, and it represents a rare but serious complication of childhood chickenpox.- - - - - - - - - - ranking = 0.16666666666667keywords = arteritis (Clic here for more details about this article) |
