Neurologic manifestations, afflicting up to 70% of SLE patients, include psychosis, seizures, chorea, neuropathies, and stroke. MRI is useful in evaluation of lupus patients and several reports have documented cerebral atrophy or focal hyperintensities. We report an unusual MRI appearance in a 56-year-old woman with SLE, diagnosed on the basis of pleuritis, lymphopenia, anti-DNA antibodies, and neurologic involvement. She reported recent onset of Raynaud's phenomenon and generalized macular rash. She presented after two months of gradual deterioration with memory loss, flattened affect, dysphagia, dysarthria, anomia, and somnolence, without focal neurologic signs. Investigations included elevated ESR, reduced complement, normal CSF without oligoclonal bands, negative viral serology, normal hormone and vitamin levels, normal renal and hepatic function. Neuropsychologic testing showed widespread impairment (WAIS-R: FSIQ-63; WMS-69; DRS-98; RCPM-14; WAB AQ-78.8). CT was normal but MRI showed strikingly symmetric, confluent hyperintensities extensively involving cerebral and cerebellar white matter on T1 and T2 weighted scans. Basal ganglia and subependymal and subcortical white matter were spared. Treated with prednisone, the patient made a gradual, but incomplete, recovery. These MRI findings may reflect widespread vasculopathy or direct immunologic brain insult with or without immunologic blood-brain barrier disruption.

The hypothesis that blood rheology is of prognostic value in stroke patients was tested in a prospective study. A total of 523 patients in the rehabilitation phase of stroke (outside the acute phase reaction after stroke) were tested for blood, serum and plasma viscosity, haematocrit, fibrinogen, red cell aggregation and deformability, ESR, white cell count, cholesterol and triglycerides. Endpoints were defined as a second stroke (lethal or not) within 2 years after the initial examination. Patients suffering such endpoints exhibit elevated blood viscosity, red cell aggregation, plasma and serum viscosity, fibrinogen and cholesterol levels, compared to patients without endpoints. It is concluded that rheological factors are associated with the prognosis after a first stroke.

Techniques of investigation of acute stroke syndromes have progressed rapidly in recent years, outpacing developments in effective stroke treatment. The clinician is thus faced with a variety of tests, each with different cost implications and each altering management to a greater or lesser extent. This review will concentrate on the basic tests which should be performed for all strokes (full blood count, ESR, biochemical screen, blood glucose, cholesterol, syphilis serology, chest X-ray and electrocardiogram). Additional tests may be required in selected cases: CT scan to diagnose 'non-stroke' lesions, to exclude cerebral haemorrhage if anti-haemostatic therapy is planned, and to detect strokes which may require emergency intervention (such as cerebellar stroke with hydrocephalus); echocardiography to detect cardiac sources of emboli; and in a few cases lumbar puncture and specialized haematological tests. Other tests, which are currently research tools, may be suitable for widespread use in the future including NMR, SPECT and PET scanning.

A 6-year-old girl with cerebral palsy developed conscious disturbance and generalized convulsion after one-hour hot herb drug bath. Physical examination on admission revealed rectal temperature 41 degrees C, hot skin, respiration 46/min, regular heart beat 98/min, BP 130/60 mmHg, Glascow coma scale 4 (E2M1V1), soft and flat abdomen, no hepatosplenomegaly, no skin rash, no focal neurological sign, increased generalized muscle ton. Laboratory data showed CBC: WBC 20400 cumm (Neutrophils 31%, Lymphocytes 69%), Hb 11.6gm%, ESR 11 mm/hr, arterial blood gas: PH 7.077, PO2 43mmHg, PCO2 57.1mmHg, HCO3- 16 mEq/L, BE-11.5mEq/L, serum sodium 143 mEq./L, potassium 5.2 mEq/L, chloride 101 mEq/L, free calcium ion 3.8mg%, GOT 63IU/L, GPT 263 IU/L, amylase 193 IU/L, alkaline phosphatase 388 IU/L, LDH 1245 IU/L, CPK 677 IU/L, total bilirubin 0.8 mg/dl, direct type 0.1 mg/dl, BUN 18 mg/dl, Glucose 35 mg/dl. Urinalysis revealed proteinuria( ) trace hematuria and pyuria, but no cast. Lumbar puncture is within normal limits. Bacteriology including blood and CSF are normal. Multiple organ failure was noted at that time. Intensive cooling methods were performed including central and peripheral cooling. We used luminal and valium to control the seizure. Condition didn't improve. Afterwards cardiopulmonary arrest developed. Patient expired 8 hours after admission despite of resuscitation. Heat stroke in infancy and childhood is different from that in adulthood. The predisposing factors are high ambient temperature, dehydration, very young baby, sweat gland dysfunction, or ectodermal dysplasia. Definition of heat stroke includes 1) rectal temperature above 41 degrees C, 2) behavioral change, 3) warm skin, wet or dry.(ABSTRACT TRUNCATED AT 250 WORDS)

From a consecutive series of 812 patients at risk of stroke we selected 100 who seemed to be at high risk (excessive stroke risk--ESR) on the following clinical criteria: either multiple reversible ischemic attacks in one carotid territory or multiple (or bilateral) severe stenotic carotid lesions. The patients of the first subgroup received medical therapy and those of the second were referred for surgery. The 100 patients were followed up for 12 months, during which 29 patients had cerebral ischemic events: 17 having stroke and 12 TIA. This study suggests that it is possible to identify beforehand subgroups of ESR patients, thereby facilitating the selection of patients for brain protection and avoiding huge trials of unselected cerebrovascular patients.

All contributory factors to the unusual occurrence of stroke in young people were evaluated in patients under age 40 admitted to the Stroke Unit of the Austin Hospital in Melbourne, Australia. Over the August 1977 to December 1980 period there were 700 admissions. Of these 14 patients were under the age of 40. There were 7 males and 7 females whose ages ranged from 17-38 years. Each patient was screened for factors which might contribute to premature vascular disease including hypertension, diabetes, smoking, obesity, and hyperlipidemia. In addition, the following tests were performed to exclude an arteritic process: full blood examination; ESR; protein electrophoresis; syphilis serology; and the presence of antinuclear factor. Each of the 14 patients suffered cerebral infarction. A summary of each case is presented in a table. In 9 patients, infarction occurred in the carotid territory of supply. Large cortical infarcts with or without subcortical involvement occurred in cases 1-8, of whom 5 had major vessel occlusion demonstrated angiographically and another had stenosing and ulcerative atheromatous disease at the extracranial carotid bifurcation. In a further 4 patients, infarction occurred within the vertebrobasilar territory and was either confined to the brain stem, the occiptal cortex, or involved both. Angiograms were performed in 2 of these patients and showed irregular narrowing of the vertebral artery which was interpreted as spasm and segmentally narrowing of the basilar artery. The final patient had several ischemic events which included right sided amaurosis fugax, and left frontal, right parieto-occipital and left occipital infarctions. Angiography was normal. All patients survived the stroke and were able to go home. There may be an interrelationship between the pathological findings of Irey et al. (1978) and the effect oral contraceptives (OCs) has on migraine. This is relevant to Case 13. Sustained exposure to OCs may produce the pathological changes described (visible as segmental narrowing angiographically). In 2 patients cerebral infarction was caused by atheromatous or hypertensive occlusive vascular disease. In Case 3 an embolus occluded the middle cerebral artery. Infarction complicating migraine was diagnosed confidently in 4 patients on the basis of typical migrainous symptomatology in the past and accompanying the stroke. Of the 12 patients fully evaluated, there were no cases of polycythemia or thrombocytosis. There were no abnormalities of the clotting factors. Almost every patient had some form of emotional upset, and there were 7 who had significant psychiatric illness and emotional problems of extreme magnitide.

Both stroke and transient cerebral ischaemic attacks occurring in younger patients may be due to systemic lupus erythematosus. Other clinical features of the disease may be absent. Initially the ESR may be normal, as may serological tests. Seizures may occur at or near the time of the vascular events. Systemic lupus erythematosus may be the cause of an asymptomatic cerebral infarct or multi-infarct dementia.

Twenty-five patients with biopsy-proven giant cell arteritis (GCA) were treated at the Royal Adelaide Hospital from 1973 to 1978. Three patients had a normal ESR on presentation. Four patients developed monocular blindness, one had gangrene of the tongue, and one had a brain-stem stroke. Six patients had concurrent autoimmune thyroid disease, one suffered from myasthenia gravis and one had ulcerative colitis--a significant observation in view of the suggestion that GCA has an immunological basis.

Sixteen patients (8 female, 8 male) with primary angiitis of the CNS (PACNS), were followed prospectively in a vasculitis clinic. Diagnosis was by angiography in patients without underlying disease. Median age at diagnosis was 36.5 years, and median duration of follow-up was 28 months. Onset was acute in 14 patients (88%), with 3.5 weeks (median) from onset symptoms to diagnosis. Three women developed symptoms within 3 weeks postpartum. The most frequent symptoms were severe headaches (12, 75%), stroke (6, 30%), transient ischaemic attack (TIA) (4, 28%), seizures (7, 44%), visual aberration (3, 19%), and cognitive impairment (5, 31%). Laboratory data included high ESR (2, 13%), leucocytosis (8, 80%), thrombocytosis (1, 6%), positive antinuclear antibody titre (3, 15%), and high levels of complement (5, 31%). Lumbar puncture was performed in 12 patients (75%). CSF analysis was abnormal in five patients (42%). EEG was abnormal in 5/9 patients. The major CT/MRI scan findings were cerebral haemorrhage (4, 25%), brain infarcts (5, 31%), brain atrophy (2, 13%) and non-specific lesions (2, 13%). Four patients had normal studies. All patients received corticosteroids (CS), and five were treated with oral cyclophosphamide. Two patients relapsed despite CS and cyclophosphamide therapy. All patients are alive, and at the last assessment, eight had a permanent neurological deficit, which included paresis (3, 19%), neurocognitive abnormalities (2, 13%), visual loss (2, 13%) and seizure activity (5, 31%). Our data suggest a non-progressive, non-fatal course in those PACNS patients diagnosed angiographically and treated with CS with or without cyclophosphamide.

In 310 patients with carotid territory stroke, we investigated whether a history of cardiac disease was more frequent among those with major stroke (n = 169) than among those with minor stroke (n = 141), and whether the two groups differed in values for blood variables directly or indirectly associated with stroke, each variable being adjusted for age and sex. A history of angina pectoris was more frequent in the major stroke than in the minor stroke group, 16% vs. 9% (p < 0.042; odds ratio, 2.2); and among female patients, a history of atrial fibrillation was more common in those with major stroke than in those with minor stroke, 35% vs. 13% (p < 0.033; odds ratio, 2.8). ESR (erythrocyte sedimentation rate) values were higher in the major than in the minor stroke group, 21 +/- 21 (mean +/- SD) vs. 15 +/- 14 mm/h (p < 0.028), as were WBC (white blood cell) counts, 9.4 +/- 3.2 vs. 7.9 +/- 2.3 x 109/l, p < 0.001. WBC counts were also higher in stroke survivors than in non-survivors, 9.6 +/- 3 vs. 8.3 +/- 3 x 109/l (p < 0.0027), as were serum creatinine values, 115 +/- 59 vs. 95 +/- 21 mumol/l (p < 0.0094). The differences between major and minor stroke patients may reflect differences in the degree of atherosclerosis and thrombogenicity.
