Abstract
Two cases with congenital homozygous factor XI deficiency developed a factor XI inhibitor following repeated plasma transfusions. Case 1 was given cyclophosphamide, intravenous immunoglobulin, and steroids. The factor XI inhibitor disappeared on day 103 and cardiac catheterization was performed without complications after giving fresh frozen plasma. Case 2 was effectively managed by plasma exchange for cardiac catheterization and surgery. However, after five plasma exchange procedures, the same plasma volume exchange was not effective in shortening the activated partial thromboplastin time (APTT). A significant heparin rebound occurred 4 h after heparin neutralization with protamine sulphate for which the patient needed to have a blood clot evacuated from around the heart.

Abstract
A huge phyllodes tumor of the breast that appeared grossly malignant in a 43-year-old woman is described. The patient suffered from a large breast tumor thatsuddenly increased in size over 5 months to occupy the entire breast. The tumorwas hard, ulcerated and 20 cm in greatest diameter. Diagnostic imaging(US, CT and MRI)demonstrated a circumscribed mass with a large cystic cavity. She underwent total mastectomy under a diagnosis of malignant breast tumor. Grossly, the cut surface of the tumor showed a large cystic cavity surrounding a fleshy, hemorrhagic and necrotic mass with a lobulared or trabeculared appearance. Unexpectedly, benign phyllodes tumor(PT)without any stromal overgrowth was diagnosed histologically. She has been doing well since total mastectomy. In our case and in many other reported cases, PT does not show any distinctive correlation between pathologic findings and tumor behavior. Thus wide local excision is the preferred initial treatment for PT.

Abstract
In order to investigate the role of Helcococcus kunzii as a colonizer of skin and as a possible participant in diabetic foot ulcers, we used a selective medium to culture both lower- and upper-extremity skin from a study group of podiatry patients (60 diabetics and 60 nondiabetics) and a control group of 50 healthy volunteers. Although differences in colonization were not statistically significant, a trend toward higher colonization rates in the group of podiatry patients was noted. H. kunzii appears to preferentially colonize the skin of the feet, and while its pathogenic role in diabetic foot ulcers is difficult to establish, it may be a previously unrecognized component of the polymicrobial flora characteristically isolated from patients with these infections.

Abstract
BACKGROUND Paraneoplastic neurologic syndromes, although rare, cause significant morbidity and mortality. They are thought to be immunologically mediated, but to date those involving the central nervous system (CNS) have not been particularly responsive to immunologic therapy. The use of the novel immunomodulator, protein A immunoadsorption, was explored to address this question. METHODS Six patients with neurologic paraneoplastic syndromes were treated with this technique, using the "off line" method. Two hundred fifty ml of plasma was perfused through a column containing protein A covalently attached to a silica matrix. The plasma was then returned to the patient. RESULTS Five of the patients responded to the therapy, with complete and durable responses in three patients with opsoclonus-myoclonus, objective, though transient, improvement in one patient with paraneoplastic brainstem encephalitis associated with a Merkel cell tumor, and stabilization and partial improvement in one patient with paraneoplastic limbic encephalitis. The patient without response developed a cutaneous vasculitis after the second treatment, and therapy was discontinued. CONCLUSIONS This therapy appears beneficial for a number of paraneoplastic syndromes, most dramatically in the opsoclonus/myoclonus syndrome.

Abstract
Fatty acids are transported to cells from a variety of different moieties in the plasma. In this study, using oleate and human umbilical vein endothelial cells, we asked whether the vehicle that delivers fatty acid to cells has an influence on its metabolism upon its incorporation into the cell. For oleate vehicles, we compared free oleate bound to albumin with oleate in low density lipoprotein (LDL) which was delipidated and reconstituted with either radiolabeled triolein or cholesteryl oleate. Using approximately physiologic concentrations of LDL and free oleate, we demonstrated by three lines of evidence unique patterns of cellular oleate metabolism for oleate delivered as triolein within LDL, for oleate delivered as cholesteryl oleate within LDL, and for oleate delivered as free oleate bound to albumin. In fact, the difference was most marked between cholesteryl oleate and triolein, even though the oleate in cholesteryl oleate and triolein was delivered in identically reconstituted LDL particles, which were presumably incorporated into the cells and degraded in lysosomes in a similar fashion. First, we demonstrated that oleate delivered as free oleate or as triolein in reconstituted LDL was desaturated and elongated to fatty acid metabolites, but cholesteryl oleate in reconstituted LDL was not similarly metabolized. The elongated and desaturated metabolites of oleate were preferentially esterified in cellular triglyceride when oleate was delivered as free oleate, but they were preferentially esterified in phospholipids when oleate was delivered as triolein in LDL. Second, we observed that there was a difference in the distribution of oleate among phospholipids when oleate was delivered as cholesteryl oleate in reconstituted LDL versus triolein in reconstituted LDL. When the oleate was delivered as triolein in reconstituted LDL, there was greater esterification in diacyl phosphatidylethanolamine, in phosphatidylserine, and in phosphatidylinositol. When oleate was delivered as cholesteryl oleate in reconstituted LDL, there was greater esterification in diacyl phosphatidylcholine. Third, there was a marked preference for oleate delivered from triolein in LDL over cholesteryl oleate in LDL for esterification into the sn-1 position of plasmalogens as a vinyl ether-linked fatty acid. These data indicate that mode of transport of fatty acid to cells influences fatty acid metabolism upon its incorporation into the cell, even when the fatty acid is delivered from the core of the same lipoprotein.

Abstract
A 17-year-old Japanese boy with severe aplastic anemia was treated with oxymetholone and prednisolone for 9 weeks without improvement. He then received 2 courses of bolus methylprednisone therapy without improvement and developed a severe liver dysfunction due to this bolus therapy. He had no HLA-compatible sibling for a bone marrow transplantation, and antithymus globulin was not available. A total of 7 lymphocytapheresis treatments were performed, using an IBM 2997 cell separator, over a period of 9 weeks. Hematological and clinical improvement were noted and felt to be related with these lymphocytapheresis treatments, and further therapy was not required. Three years have past since the patient has undergone lymphocytapheresis, and he remains in good health. Thus, lymphocytapheresis may be an alternative therapy for cases of severe aplastic anemia for those patients who have no compatible donor for bone marrow transplantation and when antithymus globulin is not available.
