Recently, allogeneic bone marrow transplantation (allo-BMT) has been established for the treatment of hematological disorders. Fifteen patients had recieved allo-BMT at Tsuchiura Kyodo General Hospital as of April 1999. In this paper, we analyzedthe results and the problems of allo-BMT at our institution. The mean age of patients was 29.2years. Seven patients had AML, 5 ALL, 1 CML, 1 non-Hodgkin's lymphoma and one had severe aplastic anemia. Bone marrow donors were all HLA-identical siblings. Most of the patients were conditioned with a combination of busulfan or totalbody irradiation, cyclophosphamide and etoposide. To prevent GVHD, cyclosporine A and methotrexate were mainly used. Patients with acute GVHD were 4 and patients with chronic GVHD were only two. Three grade I patients with acute GVHD and all with chronic GVHD did not require therapy. In spite of small numbers of transfused cells, no cases of transplant rejection were found. All these engrafted patients achieved a WBC≥1×10³μl after a median of 19.5days and a Plt≥5×10⁴/μEl after a median of 38.1days. Five of the 14 engrafted patient relapsed in a median of 6.7months and all died in a median of 9.6months. Eight are alive in complete remission for 0.2 to 39.4 months (median 21.7months). For the improvement of the disease-free survival rate after allo-BMT, the prevention of relapse and prophylaxis of GVHD and infection are important. At our institution, especially the former is important. The conditioning regimens were stronger than usual but acute and chronic GVHD was very mild, therefore GVL would be weak. If prophylaxis of GVHD is weaken and mild GVHD ans GVL occur frequently, relapse will be prevented and better results will be obtained.

Twenty six adult patients who underwent prosthetic heart valve replacement and treated anti-thrombogenic therapy, were divided into 2 groups. One was administered Warfarin alone, another was administered Warfarin plus Aspirin (162mg/day) as antiplatelet therapy. Trapidil (300mg/day) was administered to all of the patients. Platelet aggregation, plasma level of TXB₂ (stable metabolite of thromboxane A₂), and 6-keto-PGF₁ (stable metabolite of PGI₂) were measured before and 1, 3, 6 months after Trapidil therapy. Platelet aggregability suppressed in both 2 groups. Plasma TXB₂ level, and TXB₂/6-keto-PGF₁ ratio showed a tendensy to decrease (p<0.05) 6 months after administration. In the Aspirin plus Trapidil group, platelet aggregability, serum TXB₂ level, and TXB₂/6-keto-PGF₁ ratio are significantly lower than that in the Trapidil only. These results suggest that Trapidil is clinically useful for antiplatelet agent, but the combined Aspirin plus Trapidil therapy is more efficacious than the Aspirin or Trapidil single therapy.

BACKGROUND: Diabetes is considered a risk factor for acquisition of febrile urinary tract infection (f-UTI), but information on the association of diabetes with subsequent course of the disease is lacking. Thus, we investigated the clinical variables including diabetic status which determined the clinical course in patients with community-acquired f-UTI. MATERIALS AND METHODS: Patients hospitalized consecutively for f-UTI between February 2016 and January 2018 were used for this single center study. The routine laboratory tests including blood glucose and glycated hemoglobin (HbA1c) were done and empiric treatment with parenteral antibiotics was commenced on admission. The clinical course such as duration of fever (DOF) and length of hospital stay (LOS) were compared among groups classified by the clinical variables. RESULTS: Among the101 patients admitted for f-UTI, 15 patients with diabetes (14.9%) experienced significantly longer febrile period and hospitalization compared to those with hyperglycemia (n = 18, 17.8%) or those without diabetes and hyperglycemia (n = 68, 67.3%). Of the laboratory parameters tested on admission and several clinical factors, the presence of diabetes and risk factors for severe complicated infection (hydronephrosis, urosepsis, and disseminated intravascular coagulopathy) as well as HbA1c and albumin were identified as predictors for LOS by univariate analysis, whereas none of the variables failed to predict DOF. In the subsequent multivariate analysis, HbA1c levels and albumin levels were isolated as independent predictors of LOS. CONCLUSION: Patients with higher HbA1c and lower albumin levels required the longest period of hospitalization. Thus, an evaluation of diabetic and nutritional status on admission will be feasible to foretell the clinical course and better manage the subset of patients at risk of prolonged hospitalization.

  We examined how difficult it would be for the elderly living in mountainous areas to go to the nearest hospital using a Voronoi tessellation representing the mathematical concept of neighborhood. We defined the index of the nursing-care capacity for the elderly as the ratio of the number of caregivers to the number of the elderly receiving nursing-care.
  The mean age of those who drive to the hospital by themselves worked out at 70±9.8 years. Meanwhile, that of those who go to the hospital by bus or taken to hospital in a car driven by a family member came to 80±7.0years. The latter was significantly older than the former.
  The areas of the Voronoi tessellation generated by patients' places of residence were divided into three groups according to the size. The plots of these three groups of the the places of residence on the map had a three-layer and doughnut-like structure, i. e., inner-, middle-, and outer-layer.
  The index of the nursing-care capacity in 2008 was less than 1.0 for the patients under 80 years of age. This means that when those who were at the age of 50 in 2008 become old and need nursing-care, access to the hospital will become harder to them than at present. For those who are over 80 years of age and live in the outer layer that is far away from arterial road, it will be almost impossible.
  These findings suggest that outpatient care with transportation assistance by a family member at present should be reconsidered because of the future lack of care personnel. It would also be necessary to consider the welfare of older people from the geographical point of view in order to manage the problems concerning the various physical and sociological difficulties of the elderly.
