Abstract
PURPOSE To report the occurrence of a branch retinal artery occlusion with paracentral acute middle maculopathy in an otherwise healthy young man with a history of livedo reticularis (LR). METHODS Retrospective case report. PATIENTS A 21-year-old man with a history of LR being treated with pentoxifylline developed an acute branch retinal artery occlusion with initial best-corrected visual acuity at presentation of 20/80. RESULTS A thorough diagnostic work up was negative for potential causes of branch retinal artery occlusion or LR. The patient was continued on pentoxifylline and started on aspirin 81 mg daily. At five-month follow-up, vision had improved to 20/25. Optical coherence tomography testing showed a hyperreflective band in the inner nuclear layer and outer plexiform layers in the affected eye that ultimately thinned, consistent with paracentral acute middle maculopathy. CONCLUSION To our knowledge, this is the first case of branch retinal artery occlusion occurring in a patient with a history of LR. This could potentially be an early manifestation of Sneddon syndrome, a rare entity characterized by LR and cerebrovascular disease, which has been previously associated with central retinal artery occlusions.

Abstract
Sneddon's syndrome refers to the enigmatic association of ischaemic stroke and livedo reticularis. We review the Sneddon's syndrome literature examining the association of this condition with headache, including migraine. Case reports and series are stratified into two groups based on headache reference. In the group without a reference to headache, there are 208 persons, with a female to male ratio of 3 : 1. In the headache reference group, there are 175 persons, with a female to male ratio of 3.5 : 1. The proportion with headache in this second group is 58% (102 individuals), with headache described as migraine in 28 (27.5%) of the headache subjects, including six with migraine with aura. The frequency of headache is not significantly higher in persons with positive anti-phospholipid antibodies compared with the negative cohort (43% vs. 32%, P = 0.07). A review of the histopathological, radiological and serological data in Sneddon's syndrome and migraine underscores the plausibility of an association. Considered in the context of increased risk of stroke with migraine, a higher frequency of livedo in migraineurs with stroke, and the association of migraine and livedo reticularis, the question of whether livedo reticularis may be a risk marker for stroke in migraineurs is an area for further study.

Abstract
Livedoid vasculopathy (LV) is characterized by a long history of ulceration of the feet and legs and histopathology indicating a thrombotic process. We report a case of acute central retinal artery occlusion in a 32-year-old woman who had LV. She showed no discernible laboratory abnormalities such as antiphospholipid antibodies and no history of cerebrovascular accidents. Attempted intra-arterial thrombolysis showed no effect in restoring retinal arterial perfusion or vision. The central retinal artery occlusion accompanied by LV in this case could be regarded as a variant form of Sneddon's syndrome, which is characterized by livedo reticularis and cerebrovascular accidents.

Abstract
BACKGROUND Neurologic disorders are among the most common and important clinical manifestations associated with the antiphospholipid syndrome (APS). It is characterized by diverse neurological manifestations. These include stroke, transient ischaemic attack, Sneddon's syndrome, convulsions/epilepsy, dementia, cognitive deficits, headaches/migraine, chorea, multiple sclerosis-like, transverse myelitis, ocular symptoms and Guillain-Barré syndrome. MATERIAL AND METHODS We review the latest data about neurologic disorders and APS. RESULTS In patients under 45 years of age, 20% of strokes are potentially associated with APS. Our study group recently reported a correlation between primary APS and peripheral neuropathy. Only one study investigated the occurrence of peripheral neuropathy in patients diagnosed with PAPS through electrophysiological study and showed alterations in 35% of patients. The mechanism of nervous system involvement in APS is considered to be primarily thrombotic. However, other mechanisms have been described, such as antiphospholipid antibodies that bind to the neural tissue, deregulating their functions and having an immediate pathogenic effect. CONCLUSIONS This review summarizes the latest data regarding the clinical aspects, radiological and therapeutic of major neurologic manifestations associated with antiphospholipid antibodies.

Abstract
The main objective of this study was to compare clinical and laboratory data obtained from patients with primary antiphospholipid syndrome (PAPS) with and without Sneddon's syndrome (SS). A transverse study with 54 (85.2% female) PAPS patients (Sapporo criteria) was performed. Demographic, drug use, and antiphospholipid antibodies data were evaluated, as well as clinical and laboratory findings of SS. Patients were subdivided into one of two groups: PAPS with SS and PAPS without SS. Both groups were similar with respect to age (p = 0.05), gender (p = 0.34), race (p = 0.31), weight (p = 0.93), height (p = 0.27), and body mass index (p = 0.75); however, the SS group exhibited higher disease duration (96.0 ± 54.9 vs. 55.2 ± 52.0 months, p = 0.01). By definition, all PAPS with SS patients suffer from stroke, an arterial event; the frequency of stroke events (28.5 vs. 7.5%, p = 0.04), as well as of limb ischemia (100 vs. 30.0%, p < 0.0001) was higher in this group than in the PAPS without SS group. On the other hand, patients in the PAPS without SS group had more venous events, such as deep venous thrombosis, than those in the PAPS with SS group (80.0 vs. 50.0%, p = 0.03). In conclusion, an understanding of the relationship between APS and SS is important in order to identify a subgroup for which more rigorous accompaniment and therapy may be necessary.

Abstract
Sneddon's syndrome is a rare disease defined by the presence of ischemic cerebrovascular events associated with livedo reticularis. We report a retrospective study of fifteen cases, thirteen women and two men, mean age of 37.93+/-9.77 years. All patients presented one or more cerebral infarcts. Six patients had dementia. Brain magnetic resonance imaging showed several cortical infarcts with white matter involvement. Cerebral angiography performed in all patients, showed a distal arteriopathy in twelve and thrombosis of the right carotid internal artery in one. One patient had antiphospholipid antibodies. Ten patients were treated with antiplatelet agents and five with anticoagulants. The course was favorable in eight patients and stationary in three. Four patients had several recurrent infarcts, one when anticoagulants were discontinued, one taking an anti-sludge-platelet agent and two who were not initially taking any treatment.

Abstract
The importance of cerebral disease in patients with the Hughes syndrome is now becoming more widely recognized. The range of neuropsychiatric manifestations of APS is comprehensive, and includes focal symptoms attributable to lesions in a specific area of the brain as well as diffuse or global dysfunction. Patients with APS frequently present with strokes and TIA, but a wide spectrum of other neurologic features-also including non thrombotic neurologic syndromes-has been described in association with the presence of aPL. The recognition of APS has had a profound impact on the understanding and management of the treatment of CNS manifestations associated with connective tissue diseases, in particular, SLE. Many patients with focal neurologic manifestations and aPL, who a few years ago would have received high-dose corticosteroids or immunosuppression, are often successfully treated with anticoagulation. In our opinion, testing for aPL may have a major diagnostic and therapeutic impact not only in patients with autoimmune diseases and neuropsychiatric manifestations, but also in young individuals who develop cerebral ischemia, in those with atypical multiple sclerosis, transverse myelitis, and atypical seizures. We would also recommend testing for aPL for young individuals found with multiple hyperintensity lesions on brain MRI in the absence of other possible causes,especially when under the age of 40 years. It is our practice to anticoagulate patients with aPL suffering from cerebral ischemia with a target INR of 3.0 to prevent recurrences. Low-dose aspirin alone (with occasional exceptions)does not seem helpful to prevent recurrent thrombosis in these patients. Our recommendation, once the patient has had a proven thrombosis associated with aPL, is long-term (possibly life-long) warfarin therapy. Oral anti coagulation carries a risk of hemorrhage, but in our experience the risk of serious bleeding in patients with APS and previous thrombosis treated with oral anticoagulation to a target INR of 3.5 was similar to that in groups of patients treated with lower target ratios. Although a double-blind crossover trial comparing low molecular weight heparin with placebo in patients with aPL and chronic headaches did not show a significant difference in the beneficial effect of low molecular weight heparin versus placebo, in our experience selected patients with aPL and neuropsychiatric manifestations such as seizures, severe cognitive dys-function, and intractable headaches unresponsive to conventional treatment may respond to anticoagulant treatment. The neurologic ramifications of Hughes syndrome are extensive, and it behoves clinicians in all specialties to be aware of this syndrome because treatment with anticoagulation may profoundly change the outlook for these patients.

Abstract
Condição adquirida, sistêmica, caracterizada por tromboses recorrentes no sistema arterial, venoso ou ambos, a síndrome antifosfolípide pode ser primária ou secundária, esta última mais associada ao lúpus eritematoso sistêmico e menos freqüentemente a infecções, fármacos e outras doenças. São marcadores sorológicos da síndrome antifosfolípide os anticorpos antifosfolípides anticoagulante lúpico e anticardiolipina. O critério diagnóstico primário inclui trombose arterial ou venosa e morte fetal recorrente. Cerca de 41% dos pacientes apresentam lesões cutâneas como primeiro sinal da síndrome, que também pode provocar livedo reticular, ulcerações cutâneas, vasculite livedóide, entre outras manifestações. Seu controle consiste principalmente no tratamento e profilaxia da trombose com anticoagulantes e antiagregantes plaquetários.

Abstract
Thromboangiitis obliterans (TAO) and antiphospholipid syndrome (APS) share the clinical characteristics of arterial thrombosis and recurrent thrombophlebitis. Although the association of anticardiolipin antibodies (aCLa) and TAO has been previously recognized, the prevalence and the clinical impact of this association remains unclear. aCLa were measured by double ELISA in patients with TAO (n = 47), premature atherosclerosis (pASO) (n=48) and otherwise healthy individuals (n = 48). Antibody status was then compared to clinical presentation and outcomes in patients meeting the diagnostic criteria for TAO. The prevalence of aCLa was significantly higher in patients with TAO (36%) compared to either pASO (8%; p = 0.01) or healthy individuals (2%; p < 0.001). Patients with TAO and a high antibody titer tended to be younger and suffer a significantly higher rate of major amputations compared to those without the antibody (100% versus 17%; p = 0.003). Clinical features of TAO not significantly altered by the presence of aCLa included upper limb involvement, digital necrosis, superficial thrombophlebitis (or deep venous thrombosis). Protein C, protein S, and anti-thrombin III were normal in all individuals. TAO is associated with an increased prevalence of aCLa. The presence of a high antibody titer in these patients is associated with increased morbidity, including major limb amputation. In patients meeting the diagnostic criteria for TAO, screening for aCLa should be considered. Although attractive, the efficacy of chronic anticoagulation in this setting remains to be proven.

Abstract
Sneddon syndrome is characterized by livedo reticularis and multiple cerebral infarctions. Skin and central nervous system symptoms usually have a synchronous onset and at times initial symptoms affect one of them, the other lagging several years behind. We here report a patient with Sneddon syndrome who developed multiple cerebral infarctions more than 10 years after the onset of livedo reticularis. While the neurological symptoms were apparent, the patient did not display active skin manifestations. Laboratory findings excluded collagen diseases, antiphospholipid antibody syndrome, and inherited quantitative deficiency of protein C, protein S and antithrombin III. Abnormal findings included extremely elevated levels of beta-thromboglobulin and platelet factor-4 in the blood, although these acute phase markers of thrombosis were examined several years after the onset of cerebral infarctions. Platelet activation may have caused Sneddon syndrome in the present case.

Abstract
BACKGROUND Sneddon's syndrome is defined as a combination of idiopathic livedo racemosa generalisata and symptoms of cerebrovascular defect. The disease usually starts with vascular symptoms in the epidermis, with neurological deficits becoming evident later. For this reason, histological examination of skin biopsies and determination of arteriolar occlusion is of particular importance for reliable categorization and early diagnosis. To date, these methods have been considered to be too insensitive. OBJECTIVES To evaluate the sensitivity of skin biopsies in Sneddon's syndrome. METHODS We took a total of five deep punch biopsies (4 mm) from different areas of the livedo (three from white and two from red areas) in 15 patients. Present knowledge of the pathogenic relationships and the particular anatomical features of the skin were taken into account. RESULTS The method had a sensitivity of 27% with one biopsy, 53% with two biopsies and 80% with three biopsies taken from white areas in all cases. CONCLUSIONS Skin biopsies using the method presented achieved a high sensitivity, suggesting that the diagnosis in clinically suspected cases could be confirmed in the majority of cases with this technique.

Abstract
The antiphospholipid syndrome is an acquired multisystem disorder of hypercoagulation, which may be primary or secondary to underlying diseases. Serologic markers for the syndrome are the lupus anticoagulant and anticardiolipin antibodies. Clinical features include recurrent thrombotic events (arterial or venous), repeated fetal loss, and thrombocytopenia. Cutaneous manifestations may occur as the first sign of antiphospholipid syndrome. These include livedo reticularis, necrotizing vasculitis, livedoid vasculitis, thrombophlebitis, cutaneous ulceration and necrosis, erythematous macules, purpura, ecchymoses, painful skin nodules, and subungual splinter hemorrhages. Antiphospholipid syndrome may also be associated rarely with anetoderma, discoid lupus erythematosus, cutaneous T-cell lymphoma, or disorders that closely resemble Sneddon or Degos syndromes. Noninflammatory vascular thrombosis is the most frequent histopathologic feature observed. Prophylaxis and treatment of thrombosis in patients with antiphospholipid syndrome relies principally on anticoagulant and antiplatelet agents.

Abstract
Sneddon syndrome--cerebrovascular lesions and livedo racemosa--is a distinctive and uncommon disorder delineated by Sneddon in 1965. The clinical hallmarks are generalized livedo racemosa and central nervous system ischemia. Cutaneous vascular changes begin with intimal endothelial proliferation and fibromucinous matrix formation, leading to obstruction and obliteration of the vessel. The disorder is slowly progressive. No effective treatment is available, but platelet-inhibiting agents or newer antithrombotic agents may offer some hope in preventing or minimizing serious sequelae of this disease.

Abstract
BACKGROUND There is limited neuropathologic information available from cases of Sneddon's syndrome in which strokes are associated with livedo reticularis. Pathogenesis of the syndrome is controversial, although current opinion favors a coagulopathy, often with antiphospholipid antibodies. We describe a case lacking antiphospholipid antibodies but having a granulomatous infiltration of the leptomeninges. CASE DESCRIPTION The patient presented at age 29 with stroke, livedo reticularis, essential hypertension, and Raynaud's phenomenon. Assessment uncovered no underlying disease, including absent antiphospholipid antibodies. A leptomeningeal biopsy showed granulomatous infiltration. CONCLUSIONS The findings suggest that an inflammatory process plays a role in at least some cases of Sneddon's syndrome.

Abstract
We present a case of Sneddon's syndrome with high titers of antiphospholipid antibodies (APLA), in which the leading symptom was an incapacitating memory defect. MRI revealed vasculitic lesions of the central nervous system (CNS). Therefore immunosuppressive therapy was started with steroids and cyclophosphamide pulses. The transient beneficial effects of such a therapy will be discussed.

Abstract
BACKGROUND AND PURPOSE Sneddon's syndrome, characterized by generalized livedo racemosa and cerebrovascular lesions, is an underdiagnosed disease. We evaluated clinical, laboratory, histological, and neuroradiological findings in a series of 17 patients to improve diagnostic criteria for Sneddon's syndrome. METHODS Patients with generalized livedo racemosa and cerebrovascular events were included in the study. All underwent neurological and dermatological examination, skin biopsy, computed tomographic scan, magnetic resonance imaging as well as magnetic resonance angiography, sonography of the extracranial arteries, and a comprehensive laboratory protocol. RESULTS Completed stroke was present in eight patients, and 15 reported transient neurological deficits. Magnetic resonance imaging yielded cerebral abnormalities in 16 of 17, whereas computed tomographic scans were abnormal in only 12 of 16 patients. Magnetic resonance imaging revealed more lesions in individual patients than did computed tomography. Magnetic resonance angiography demonstrated patent intracranial vessels in 16 of 17 patients. Skin biopsy showed distinct histopathological findings in all patients. The involved vessels were small to medium-sized arteries at the border between dermis and subcutis. Early inflammatory reactions were followed by subendothelial proliferation and a late fibrotic stage. Laboratory examinations showed impaired creatinine clearance in eight patients, whereas all other laboratory tests, including antiphospholipid antibodies, were normal. CONCLUSIONS In this series, magnetic resonance imaging and skin biopsy were useful for confirmation of the diagnosis of Sneddon's syndrome. Magnetic resonance findings were not specific, but the high sensitivity for detection of asymptomatic brain lesions helped to confirm the diagnosis in patients with transient symptoms. Histological features of skin biopsies were characteristic if appropriate techniques were employed.
