Miconazole at dosages up to 30 mg/kg/day was given intravenously to seven patients with complicated courses of disseminated coccidioidomycosis. Six had received treatment with amphotericin B previously and five of these patients could be evaluated for the efficacy of the treatment. In three patients the condition failed to respond to therapy, another patient required intratracheal administration of amphotericin B later, and the fifth patient had an equivocal response to treatment. Severe phlebitis, pruritus, nausea, vomiting, hyperlipidemia, and thrombocytosis were frequent side effects. These limited unfavorable results indicate that until controlled studies demonstrate its safety and efficacy, therapy with miconazole should be reserved for highly selected patients with disseminated coccidioidomycosis who cannot receive amphotericin B.

Effect of corticosteroids (steroids) on some hemostatic parameters was serially studied in 23 children with minimal change nephrotic syndrome (MCNS). Increased platelet count, erythrocyte sedimentation rate (ESR), cholesterol, fibrinogen, fibrin(ogen) degradation products (FDP), alpha 2-macroglobulin (alpha 2M), alpha 2-antiplasmin (alpha 2AP) and protein C, and reduced antithrombin III (ATIII) and plasminogen (Plg) were noted in relapse before steroid therapy began. With institution of oral prednisolone, FDP started to fall, and platelet count, cholesterol, alpha 2M, ATIII, Plg, alpha 2AP and protein C started to increase despite unchanged nephrotic state from that before the therapy. In remission induced by prednisolone, platelet count, cholesterol, alpha 2M, ATIII, Plg, alpha 2AP and protein C were still increased, but normalized off therapy. ESR, fibrinogen, FDP, alpha 2M and protein C correlated inversely with serum albumin and directly with cholesterol and urine protein excretion. In contrast, ATIII and Plg correlated directly with serum albumin and inversely with cholesterol and urine protein excretion. A direct correlation was only noted between alpha 2AP and the dose of prednisolone. The data indicate that steroids appear to be a thrombogenic factor by accerelating thrombocytosis and hyperlipidemia, and by reducing plasma fibrinolysis in children with MCNS.

The purpose of this study was to determine which factors were associated with an increased risk of thrombo-hemorrhagic complications in a historical cohort of 100 consecutive and unselected patients with essential thrombocythemia (ET) in whom busulfan treatment was given when platelets were more than 1,000 x 10(9)/L and/or a major thrombotic or hemorrhagic event occurred. The incidence of major hemorrhagic complications was very low (0.33%/person-time at risk [pt-yr]) in comparison with that of thrombotic episodes (6.6%/pt-yr). In an adequate and appropriate control historical group of 200 patients, no severe hemorrhages were recorded and the incidence of thrombotic events was 1.2% pt-yr. Thus, the analysis of risk factors was restricted to this latter group of events. Age, a previous thrombotic event, and long duration of thrombocytosis were identified as major risk factors for thrombosis, while smoking, diabetes mellitus, hyperlipidemia, and hypertension did not influence the rate of thrombotic episodes.

Intravenous miconazole can produce responses in patients with various manifestations of coccidioidal disease, even if they have failed to respond to amphotericin B. In 4 large series of 33, 33, 46 and 31 courses of miconazole for skin and soft tissue, chronic pulmonary, meningeal and skeletal coccidioidomycosis, response rates of 40, 72, 31 and 32%, respectively, were achieved; 60, 75, 78 and 56%, respectively, of those responding subsequently relapsed at the site(s) of earlier involvement. This suggests that the therapeutic effect of the relatively brief courses used (mean, 1 to 3 months) is fungistatic in vivo. Common side effects of intravenous miconazole include phlebitis, pruritus, anaemia, thrombocytosis, hyponatraemia, nausea, hyperlipidaemia, vomiting, central nervous system effects, and rashes. The place of miconazole relative to amphotericin B and ketoconazole has not been determined, and requires further comparative studies. Information on the results of different regimens, particularly longer courses, would also be of interest.

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.

Reactive thrombocytosis (RT) has earlier been reported to occur as a response to various situations and conditions, such as post-splenectomy, hematopoietic disorders, major trauma and operations, neoplasms and inflammations. In cardiac surgery the main interest has focused on thrombocytopenia that occurs after cardiopulmonary bypass (CPB) and the risk of postoperative bleeding, rather than the possibility of a late occurrence of RT as a risk factor for thrombotic complications after coronary artery bypass grafting (CABG). Between 1989 and 1992, on routine blood examinations we noticed a group of CABG patients (n = 297, Group II, 19.5%) that, 1 week after operation, showed thrombocytosis with significantly increased platelet count (521 +/- 96 x 10(3)/mm3) compared to patients with normal platelet counts (Group I, n = 1521, 185 +/- 125 x 10(3)/mm3); P < 0.001. Patient characteristics, coronary angiography findings, operative data and perioperative complications were analyzed for the two groups. There were significantly more patients with hyperlipidemia, smoking and previous myocardial infarction in Group II than in Group I; P < 0.05. Age, sex, clinical characteristics, angiography findings and operative data did not differ between the groups. There were no differences in postoperative bleeding or the need of transfusion between the groups. However, Group II (RT) patients had significantly more postoperative myocardial infarctions, 4.4% compared to 0.7% Group I; P < 0.001. Early symptomatic vein graft occlusion (0-7 days postoperatively) was not different between the groups, while there were significantly move late symptomatic vein graft occlusions (7-60 days postoperatively) in Group II (RT) 4.4% than in Group I 1.1%; P < 0.001.(ABSTRACT TRUNCATED AT 250 WORDS)

This article describes the first autopsy case of heme oxygenase (HO)-1 deficiency. A 6-year-old boy who presented with growth retardation; anemia; leukocytosis; thrombocytosis; coagulation abnormality; elevated levels of haptoglobin, ferritin, and heme in serum; a low serum bilirubin concentration; and hyperlipidemia was diagnosed as HO-1 deficient by gene analysis several months before death. Autopsy showed amyloid deposits in the liver and adrenal glands and mesangioproliferative glomerular changes in kidneys, in addition to an irregular distribution of foamy macrophages with iron pigments. Fatty streaks and fibrous plaques were noted in the aorta. Compared with HO-1--targeted mice, the present case seems to more severely involve endothelial cells and the reticuloendothelial system, resulting in intravascular hemolysis, disseminated intravascular coagulation, and amyloidosis with a short survival. This contrasts to the predominant iron metabolic disorders of HO-1--targeted mice with a long survival.

Plasma membranes are fluid structures and the maintenance of fluidity is a prerequisite for function, viability, growth and reproduction of cells. Membrane fluidity is the reciprocal of membrane microviscosity, which in turn is inversely proportional to rotational and lateral diffusion rates of membrane components. In the absence of constraints most lipids and unrestrained integral proteins freely diffuse in the plane of the membrane with high diffusion coefficients. The fluid mosaic model of plasma membrane structure is essentially still valid but this model is by its nature a macroscopic one. At present, attention is focused on molecular structural details of protein-lipid interactions and on the static and dynamic structure of membrane proteins. Highly potent new macroscopic and microscopic methods have been developed to measure translational diffusion of membrane lipids and proteins. The microscopic methods can reveal diffusion via encounters between labeled molecules. Fluorescence anisotropy measurements are the most widely used techniques in biological research. The use of different permeant and non-permeant fluorophores have contributed much to a better understanding of the changes in the ordered states and motional freedom of the membrane phospholipids in different cells during development, aging and physiological functions as well as in pathological conditions. The application of fluorophores with non-random distribution have shed light on the asymmetrical changes between the outer and inner domain of the lipid bilayer and on the dynamics of 'flip-flop' in signal transduction. Membrane fluidity was shown to have a decisive role in the efficiency of ligand binding, in the outcome of direct cell to cell contacts and in the modulation of the activity of membrane enzymes. Cell filtrability reflects whole cell viscosity that can not always be correlated with the fine changes in membrane fluidity. Cell viscosity depends inter alia on the size and shape of the cells as well as on membrane rigidity. In contrast to this, membrane fluidity is only dependent on the freedom of mobility of the membrane constituents. Increased release of free radicals and reactive oxygen specie (ROS) affect membrane fluidity, cellular Ca2+ homeostasis, induce lipid peroxidation and finally cell death. Investigation of membrane fluidity proved to be a useful and sensitive additional method to obtain a better insight into the mechanisms by which different compounds, drugs and contact with foreign surfaces are affecting cellular functions. The measurements of membrane fluidity may gain more widespread use for monitoring the safety and efficacy of these actions. During the last few years, changes in membrane fluidity of blood cells have been reported during development and aging and as a result of physiological cell functions. Membrane fluidity changes have been described in thrombocythaemia, hyperlipidaemia, hypercholesterolaemia, hypertension, diabetes mellitus, obesity, septic conditions and in allergic and burnt patients, in alcoholics, in Alzheimer's disease and in schizophrenia. A short summary is given on red cell membrane fluidity changes in a Hungarian triosephosphate isomerase (TPI)-deficient family, reflecting how the very subtle changes in membrane fluidity can help to establish underlying biological differences between the clinical phenotypes of a severe enzyme (TPI) deficiency caused by the defect of a single gene in two brothers one with and one without neurological symptoms.

Little is known about the management of coronary thrombosis in myeloproliferative disease. The occurrence of myocardial infarction in myeloproliferative disease is mostly attributed to coronary thrombosis due to hyperviscosity and thrombocytosis. We presented three cases of acute myocardial infarction associated with polycythemia vera in one patient (male, age 33 years) and essential thrombocytosis in two patients (male, ages 36 and 46 years). None of the patients had diabetes mellitus, hypertension, hyperlipidemia, or a positive family history. One patient with early presentation received thrombolytic therapy, and all the patients were treated with aspirin, beta-blocker, angiotensin 2 receptor blocker, statin, low-molecular-weight heparin, parenteral nitrate, and clopidogrel for acute coronary syndrome, and hydroxyurea for essential thrombocytosis. Control angiographies showed patent coronary arteries in all the cases.

It has been estimated that up to 10% of hypercoagulable state manifestations in patients with inflammatory bowel disease (IBD) are ischemic strokes. The literature search through MEDLINE and EMBASE highlighted 33 case reports of IBD patients complicated with cerebral arterial infarction during the course of their disease. Most of these patients presented with either left or right sided hemiparesis on admission, while the most common site of arterial infarction was either the right or the left middle cerebral artery. Thrombocytosis and anemia were the most commonly observed potential risk factors for stroke in the laboratory analysis. Other coagulation abnormalities, hereditary thrombotic mutations, hyperhomocysteinemia, hyperlipidemia, structural cardiac abnormalities, endocarditis and cerebral artery vasculitis have also been reported in some of the cases that were reviewed. Even though many of these findings are commonly observed in IBD patients, literature data is still controversial about their causal relationship to ischemic stroke. Similarly, there is also lack of steady evidence and official guidelines for stroke management in both children and adults with IBD comorbidity. Finally, an algorithm based on both the American Heart Association and European Stroke Organization guidelines for stroke management and prevention in the general population, is presented as a reference point for the treatment of IBD patients who are complicated by an ischemic cerebral event.
