    Objective To examine the incidence, underlying disease and clinical features of left ventricular aneurysm (LVA) not related to coronary artery occlusion.
    Methods Retrospective review of consecutive patients who underwent both left ventriculography and coronary angiography.
    Patients LVA was confirmed in 11 of 2, 348 consecutive patients (0.47%).
    Results The location of LVA was mainly in the apical region (81.8%). In five of the 11 patients (45.5%), the underlying heart disease was hypertrophic cardiomyopathy (HCM), including 4 patients of dilated phase and one patient of midventricular type. The serial ECG changes from left ventricular hypertrophy to abnormal Q wave and endomyocardial biopsy were useful for the differential diagnosis of these cases against myocardial infarction. The underlying disease of the remaining patients was: myocarditis (2 patients), arrhythmogenic right ventricular dysplasia (1 patient), Chagas' disease (1 patient), glycogen storage disease (1 patient), and sarcoidosis (1 patient). Ventricular tachycardia appeared in 9 of 11 cases (81.8%) including 2 patients with sustained ventricular tachycardia.
    Conclusion LVA formation without coronary artery disease was a rare phenomenon. The underlying disease was varied but the incidence of hypertrophic cardiomyopathy in the dilated phase was comparatively high. Ventricular tachycardia was a significant complication in these patients.

    Objective This study was performed to examine the role of the endothelial constitutive NO synthase (ecNOS) gene in patients with abdominal aortic aneurysm (AAA).
    Methods We determined the distributions of polymorphism in intron 4 of the ecNOS (ecNOS4) gene, amplified by polymerase chain reaction, and compared the allele frequencies between subjects with abdominal aortic aneurysms (AAAs) and healthy individuals.
    Patients Fifty-eight patients with AAAs and 410 race-matched healthy controls were studied.
    Results Two alleles of the ecNOS4 gene, containing 4 (a-allele) and 5 (b-allele) repeats, were identified. We found that the a-allele frequency of this gene was significantly higher in the surgical than in the non-surgical group.
    Conclusion The results of this study suggest that the a-allele of the ecNOS4 gene is indicative of the need for surgery for AAA. Analysis of the alleles of the ecNOS4 gene polymorphism could provide useful information concerning the clinical course of AAA progression.

    Objective We designed the present study to evaluate the association of various lipid and fibrinolytic components with coronary artery stenosis with respect to the triglyceride (TG) level.
    Methods Levels of TG, remnant-like particle cholesterol (RLP-C), total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), lipoprotein-(a), uric acid, blood glucose, tissue plasminogen activator (t-PA), t-PA inhibitor type 1, antithrombin III, and protein C were measured in 208 patients who underwent diagnostic coronary angiograms.
    Patients Of these 208 patients, 59 were hypertriglyceridemic (150 mg/dl or higher) and 149 were normotriglyceridemic.
    Results Both LDL-C and HDL-C showed significant differences between patients with and those without coronary artery stenosis in both hypertriglyceridemic and normotriglyceridemic patient subgroups. However, RLP-C showed a significant difference in the normotriglyceridemic patient subgroup (p=0.012) but not in the hypertriglyceridemic patient subgroup (p=0.736).
    Conclusion Our current retrospective study disclosed that RLP-C levels are closely associated with coronary artery stenosis in patients with normal TG levels.

    Objective In order to investigate the role of eotaxin in pleural diseases, we measured eotaxin in pleural effusions and studied the relationship between eotaxin levels and recruitment of inflammatory cells, particularly eosinophils. Interleukin-8 (IL-8) and monocyte Chemoattractant protein-1 (MCP-1) levels were also measured for comparison.
    Methods We evaluated 47 pleural effusion samples, 7 transudates and 40 exudates. The exudates consisted of 19 malignant, 11 tuberculous, and 5 parapneumonic effusions, and 5 effusions of other etiologies. Chemokine levels were measured by specific sandwich enzyme-linked immunosorbent assays.
    Results Eotaxin was detected in all samples examined, but the levels did not differ significantly among the exudates. There was no significant correlation between the levels of eotaxin and MCP-1 or IL-8. The level of eotaxin but not the others was significantly higher in eosinophilic effusions (>10% eosinophils among white blood cells in the fluid) than in non-eosinophilic fluids. The number of eosinophils in pleural effusions was significantly correlated with the eotaxin levels, but not with the levels of other chemokines. The number of neutrophils was significantly correlated with IL-8 but not with the others.
    Conclusions Results suggest that eotaxin contributes to the migration of eosinophils in pleural inflammation. Taken together with the correlation between IL-8 and neutrophils, it appears that the predominant type of pleural inflammatory infiltrate is controlled, at least in part, by the subgroup of chemokines expressed in the pleural space.

    A 60-year-old woman was admitted to our hospital for repeated consciousness disturbance. Blood examination showed hyperammonemia, and plasma amino acid analysis revealed a marked increase in the citrulline level. To establish a diagnosis, a percutaneous needle biopsy of the liver was performed. The determination of the urea cycle enzyme activities revealed a selective marked decrease in argininosuccinate synthetase activity, indicating the final diagnosis of type II citrullinemia. The mean survival period of this disease after the appearance of symptoms has been reported as 26.4 months, and most conservative treatments are not effective. We performed a living related partial liver transplantation. Over the subsequent 13-month follow-up, the patient's condition has remained fairly good.

    A 51-year-old man was admitted to our hospital because of hematochezia and painful keratotic plaques involving both hands. He had gastrointestinal polyposis, and a history of liver hemangiomas and thyroid tumor. Numerous papules on the face and papillomatosis on the oral mucosa were present. A diagnosis was made as a typical case of Cowden's disease according to the criteria proposed by Salem and Steck (J Am Acad Dermatol 8: 686, 1983). The patient was not correctly diagnosed initially in spite of typical manifestations of Cowden's disease, mainly due to his concomitant manifestations which occurred chronologically.

    A 75-year-old man was admitted due to nephrotic syndrome, purpura on the legs, which was associated with hepatitis C virus (HCV), and type II mixed cryoglobulinemia. Renal biopsy revealed features of cryoglobulinemic glomerulonephritis. Since the patient was elderly and the HCV genotype was Ib, interferon-alpha for reducing HCV was not indicated. Four sessions of cryofiltration and the administration of corticosteroids improved the proteinuria and renal function strikingly without adverse effects. This case demonstrates that an elderly patient who has nephrotic syndrome caused by cryoglobulinemic glomerulonephritis associated with HCV can be treated safely by cryofiltration with low doses of oral corticosteroids.

    A 44-year-old woman suffered from recurrent fever, edema and fatigue. Laboratory data revealed renal dysfunction, low proteinemia, disseminated intravascular coagulation (DIG) and myelodysplasia. A renal and lymph node biopsy showed a marked angiogenesis. Serum levels of vascular endothelial growth factor (VEGF), and interleukin (IL)-6 were markedly increased, suggesting a pathogenesis related to VEGF-induced angiogenesis. The symptoms were remitted after treatment with cyclosporin A. No evidence of solid tumors, malignant lymphoma, Castleman's disease or POEMS (polyneuropathy, organomegaly, endocrine disorder, M-proteinemia and skin change) syndrome, reported to induce a high serum VEGF level, was obtained. This case may have involved an unknown mechanism which induced an overexpression of VEGF and IL-6.

    A 31-year-old woman visited an out-patient clinic, because of low-grade fever and general fatigue. She was referred to our hospital and admitted for examination of an abnormal shadow which had been found on the chest radiograph. She had experienced faint right lateral chest pain several times on the deep inspirations. Chest radiography showed a mass shadow with calcification in the right lower lung field on the mediastinal side. Chest radiographic computed tomography showed a 6×6 cm tumor in the right lung field. There were low-density areas with septae inside the tumor. Bone scintigraphy showed extremely high uptake of 99mTc-HMDP in the tumor. After surgical resection and pathological examination, we concluded that the tumor was an extensively calcified benign hemangioma of the diaphragm.

    A 37-year-old man who suffered from bilateral pleural effusions, subcutaneous abdominal induration and blood eosinophilia, was admitted to our hospital. He had ingested raw crabs at a pub-restaurant before the onset of his symptoms. His pleural effusions were chyliform containing cholesterol crystals, and a high level of immunoglobulin E (36, 580 Ill/ml) and anti-Paragonimus miyazakii antibody were detected. He was effectively treated with praziquantel. This case suggests that paragonimiasis should be strongly suspected if blood eosinophilia, pseudochylothorax, and a high level of immunoglobulin E in pleural effusion are detected.

    A 57-year-old woman noticed a pulsatile shooting headache in her right temporal region 3 days after extraction of a tooth from the right mandibula. The following day, a localized headache over the right superficial temporal artery (STA), low grade fever, and jaw claudication appeared and progressed subacutely. Seven days after the onset, magnetic resonance imaging and angiography (MRI/MRA) disclosed inflammatory swelling of the right temporal muscle and dilatation of the right STA. All the symptoms disappeared following antibiotic treatment, and neuroimaging findings were improved. In conclusion, MRA is thought to be useful to non-invasively identify reversible inflammatory dilatation of extracranial vessels.

    An 87-year-old woman with antiphospholipid syndrome accompanied by cortical blindness and thalamic syndrome resulting from infarction of the posterior cerebral artery is reported. She was hospitalized because of laceration of the head. Two months later, she complained of loss of visual acuity, sharp pain and numbness involving the left half of the body except her face. New right posterior lobe infarction and the existence of old left infarctions were confirmed by serial CT scans. Helical CT scan revealed embolization of the posterior cerebral artery with atherosclerotic stenosis. Serological examination showed biologically false-positive and positive findings for lupus anticoagulant. She was treated with warfarin potassium and clonazepam.

    Three Japanese outpatients with human immunodeficiency virus (HIV) infection on anti-retroviral therapy showed evidence of influenza in January 1999. CD4+ T cell counts of these patients prior to the diagnosis of influenza were 72, 248, and 152/mm3, and HIV RNA levels were 19, 953, 1, 259, and 1, 585 copies/ml, respectively. Fever continued 4 to 5 days with no severe complications. One patient showed post-influenzal bronchitis which was effectively treated by antibiotics. None of these patients showed increased serum HIV RNA levels during and after influenza, however, in one patient, a transient reduction of CD4+ and CD8+ cells was seen during the active phase of influenza. Although symptoms of influenza in HIV carriers are generally mild and similar to those in healthy adults, careful follow-up is needed as symptoms of influenza in some HIV infected patients can be prolonged and serious.
