Pulmonary embolism secondary to deep vein thrombosis is a frequent cause of death in stroke patients. In a multicentre study of deep vein thrombosis prophylaxis, 112 patients with cerebral infarction and leg paresis were given aspirin 300 mg three times a day (t.d.s.) alone or with dipyridamole 100 mg t.d.s. To screen for deep vein thrombosis liquid crystal thermography of the legs was performed daily for 15 days on all patients. Those patients with positive thermography underwent immediate X-ray venography of the appropriate limb as the definitive investigation for venous thrombosis. Twenty-two patients had positive thermograms, of whom 16 had confirmed deep vein thrombosis as demonstrated by X-ray venography. Only 8 of the 22 had clinical signs of deep vein thrombosis and 2 of those had a negative venogram. Of the 14 patients with positive thermography but negative clinical signs 10 had positive venograms. Difference in the incidence of deep vein thrombosis in the two treatment groups was not demonstrated. It is concluded that occult deep venous thrombosis is common after ischaemic stroke and it can occur without clinical signs. Liquid crystal thermography is a simple, rapid and cheap screening test that will allow the detection of clinically unrecognized thrombosis.

A 13-year-old boy was admitted to this hospital for evaluation of pitting edema of both legs. Three years ago, he had been diagnosed to have nephrotic syndrome. Two and half years ago, because of persistent heavy proteinuria, poor response to steroids and frequent relapse of disease, a renal biopsy was done; characteristics of IgM nephropathy was shown. About a year previously, the patient felt dizziness and weakness of the left side of his body upon awakening one morning. Neurologic examination showed loss of muscle tone, muscle power and deep tendon reflexes. Sensory and cranial nerve function were intact. Blood pressure was normal. The CT scan of brain showed a patch of low attenuation area in the right temporal region, obliteration of the right cortical sulci and mild compression of right lateral ventricle. A diagnosis of nephrotic syndrome with right cerebral infarction was made. The patient's condition became stable two days later after mannitol infusion, correction of electrolytes, and supportive therapy. According to literature, most cases of nephrotic syndrome complicate with renal thrombosis, pulmonary emboli, and deep vein thrombosis. Few cases complicate with cerebral thrombosis and infarction. If patient have low plasma albumin and anti-thrombin III level, hyperfunction of platelet aggregability and use long-term diuretic therapy, they may be at higher risk of thromboembolic complications. If thromboembolic complications exist, anticoagulation treatment should be instituted. Prophylactic therapy with aspirin or dicumarol is not currently recommended.

Twenty-one patients with anti-phospholipid antibodies (APLA), who were selected from 104 patients with antinuclear antibody or anti-DNA antibody, were studied to define clinical characteristics of APLA. Of the 21 patients, the incidences of IgG anti-cardiolipin antibody (ACA), IgM ACA, lupus anticoagulant (LAC) and BFP-STS were 20, 7, 11 and 12, respectively, and they were highly related with each other. The number of items of the 1982 ARA revised criteria for the classification of SLE was significantly low (mean value = 3.3), and also the level of serum C 4 was significantly high (mean value = 88% of normal) compared with those in patients without APLA. The incidence of thrombocytopenia and hemolysis was significantly high when compared with those in patients without APLA, and they were closely related to the presence of LAC. The incidence of thrombosis was markedly high (48%), 10 of 21 patients, especially those of cerebral infarction and deep vein thrombosis. Cerebral infarction was significantly associated with LAC. The obstetric complication was 4 of 13 patients (31%) in the incidence, which was significantly high compared with that in patients without APLA. Of them, natural abortion was closely associated with LAC. Based on these observations, it seems that autoimmunological disease activity in patients with APLA may be slight to mild, and strongly suggested that APLA may play an important role particularly in the pathogenesis of acquired thrombotic tendency.

Recent findings on the relation between alcohol abuse and ischaemic brain infarction are reviewed. Much of the association has hitherto been explained by the effects of confounding factors such as smoking. Alcohol increases blood pressure in both hypertensive and normotensive subjects and alcohol induced hypertension enhances the risk of both hemorrhagic and ischaemic strokes. Analysis of case histories shows that alcohol abuse has precipitated cerebral embolism in conjunction with cardiac diseases including alcoholic cardiomyopathy and paradoxical embolism due to deep vein thrombosis via atrial septal defect. Among young adults, falling when intoxicated with alcohol has caused traumatic dissection of the carotid artery and consequent brain infarction. Alcohol may predispose individuals to cerebral embolism, thrombosis and ischaemia via its effects on the coagulation cascade, platelet count and function and contractility of the cerebral vessels. Further studies are needed to prove that these mechanisms are significant and to identify any other mechanisms which may mediate the risk associated with alcohol abuse. On the basis of current data, alcohol should be considered as an independent risk factor for ischaemic cerebral infarction in young adults.

In a prospective study of the incidence of deep vein thrombosis (DVT) after stroke, and the prophylactic effect of dextran, 50 patients, admitted with a diagnosis of cerebral infarction with paresis of the lower extremity within the first 48 hours, were randomly allocated to treatment or non-treatment groups. The treatment group received 500 ml of dextran 40 on admission and on days 1 and 2, and 250 ml on days 4 and 6. Venesection was performed on admission and if necessary on day 1. The control group received no dextran or venesection. DVT was diagnosed with the 125I-fibrinogen test during the first ten days. The incidence of DVT was 54% in the treatment group and 50% in the control group. There were no statistically significant differences between the groups regarding number of DVTs needing treatment, number of positive scanning points or number of days for scan to become positive. Lethal pulmonary emboli occurred in one treated and in three control patients, respectively. Age and progress of neurologic symptoms predisposed for the development of DVT. The high incidence of DVT in stroke patients indicates the need for prophylactic routines.

Over a 3-year period, we studied 43 women who presented with severe preeclampsia prior to 34 weeks' gestation. Seven (16%) had significant levels of antiphospholipid antibodies, whereas none of the normotensive controls of similar gestational age had antiphospholipid antibodies (P less than .001). Three of the seven women with antiphospholipid antibodies suffered the following complications during the peripartum period: 1) cerebral infarction and episodes of transient monocular blindness; 2) pulmonary embolism, deep venous thrombosis, and an autoimmune flare in the postpartum period; and 3) transient monocular blindness and amnesia after delivery. Our experience suggests that antiphospholipid antibodies are found in a substantial proportion of cases of early-onset severe preeclampsia and have important clinical implications. We suggest that patients with early-onset severe preeclampsia be screened for antiphospholipid antibodies; if antibodies are detected, these women should be considered for prophylactic anticoagulation therapy.

Ancrod has been used in Europe for over 15 years for peripheral vascular disease, deep vein thrombosis, and central retinal venous thrombosis, and in patients at risk for thromboembolism. In a double-blind, randomized, placebo-controlled study at University Hospitals in Cincinnati, 20 acute cerebral infarction patients received a series of IV infusions of ancrod (ten) or placebo (ten) for seven days. Early fibrinolysis with a small decrease in fibrinogen was observed, and d-dimers were elevated at four hours, indicating early clot lysis. At three months, patients with moderate to severe strokes (less than 40 on the Scandinavian Stroke Scale) in the ancrod group showed average improvement by a factor of 3 over the placebo group. No bleeding, abnormal laboratory results, or deaths occurred, but ancrod was discontinued in one patient who had seizures. As a result of this study, a double-blind multicenter international clinical trial to further assess the safety and effectiveness of ancrod is being planned.

An old woman had stroke at age 67. Cerebral CT scan disclosed the low-density lesion with high-density area in the left temporal lobe, but no empty delta sign in the superior sagittal sinus. Thereafter, she had sometimes panic attacks. At the age of 70, she was admitted because of loss of consciousness probably caused by the same attack. On admission, Brain CT scan showed no fresh lesions. During the stay in the hospital, she had an episode of deep vein thrombosis of her left leg. The patient was found to have not only reduced biochemical activity but also low immunological level of AT III. Her nephew had also the low plasma AT III antigen concentration. Transesophageal echocardiography showed no abnormality, but atherosclerotic change at the aortic arch. We speculated that hemorrhagic cerebral infarction in the territory of the branch of middle cerebral artery could be induced by the arterial thrombus which was related to the hypercoagulable state associated with familial AT III deficiency, although the possibility of cardiogenic embolic infarction or of cerebral vein thrombosis could not be ruled out. Familial AT III deficiency is one of the causes of cerebral infarction even in the elderly.

We report on a woman with an Lp(a) lipoprotein level above the 99th centile of the population distribution of concentrations, who at the age of 43 had had deep vein thrombosis causing a pulmonary embolus and whose brother, who also had a very high level, had suffered a cerebral infarction at the age of 43. She had given birth to three children, all with very low birth weight, one of whom died when 3 months old. The placentas had been small and ischemic. The concurrence of a very high Lp(a) lipoprotein level, familial thromboembolic disease and recurrent placental ischemia with delivery of children with low birth weight suggests the possibility that a very high Lp(a) lipoprotein concentration may predispose to placental insufficiency, presumably arising from pathological changes in maternal uterine vessels in the placental bed. If confirmed, a very high Lp(a) lipoprotein level may be a factor to consider in women who have repeated pregnancies with placental insufficiency and who give birth to children with low birth weight.

Since January 1988, 18 patients with acetabular fractures were operated on. Seven fractures were "both columns", six were posterior wall fractures, four were of the transverse/single column types, and one was unclassified. Four patients were operated by ileo-inguinal incision alone, three by combined ileo-inguinal and posterior Kocher-Langenbeck, ten by Kocher-Langenbeck, and one by triradiate incision. Early complications were 1 DVT and 1 infection (subsided after removal of the plate from crista iliaca). One patient with brain injury developed cerebral infarction, and one multi-traumatized patient died of lung embolus after transfer to another hospital. 11 patients are back at work, one has retired, and two are seeking new education after the injury. We conclude that operative treatment is indicated for these fractures, and that the results and rate of complications are acceptable. This treatment should be centralized.
