He developed symptoms of the skin, eyes, and mouth, and lip biopsy indicated chronic GVHD. Persistent keratitis with corneal filaments and neovascularization was noted in both eyes. Sodium hyaluronate, autoserum, and 0.1% fluorometholone eyedrops were instilled for approximately 2 years to treat this keratitis, and there were no other ocular changes. Bilateral herpes simplex keratitis developed with geographic ulcers after topical betamethasone therapy, but responded to acyclovir ointment.Conclusions: Herpes keratitis should be considered in the differential diagnosis of bilateral keratitis in patients with reduced immunocompetence. During the course of chronic GVHD, corneal herpes may occur, so ocular treatment with topical corticosteroids should be managed by an ophthalmologist to monitor sight-threatening conditions such as corneal herpes.Keywords: chronic graft-versus-host disease, bone marrow transplant, corneal herpes, bilateral herpes simplex keratitis, dry eye

    Mechanical Property and Microstructure in Neutron Irradiated Fe-Cr-Mn-Al Alloys

    A series of Fe-xCr-yMn-zAl alloys have been examined by tensile test and electron microscopy following irradiation in JMTR to 5x10^ n/m^2 at about 470 K. After the irradiation, 0.2% proof stress, ultimate tensile stress and total elongation were compared with the unirradiated data. From this experiment, it can be assumed that appropriate composition in these alloys is as follows : Fe-10Cr-(20-25)Mn-3Al for ferritic alloys, and Fe-10Cr-30Mn for austenitic alloys

    Height Constitutes an Important Predictor of Mortality in End-Stage Renal Disease

    Aim. Height is an important determinant of augmentation index (AI) that anticipates cardiovascular prognosis. There is a scanty of the data whether short height predicts survival in patients with end-stage renal diseases, a high risk population. Methods. Fifty two hypertensive patients with type 2 diabetic nephropathy receiving hemodialysis and 52 patients with nondiabetic nephropathy were enrolled. In addition to AI estimated with radial artery tonometry, classical cardiovascular risk factors were considered. Patients were followed for 2 years to assess cardiovascular prognosis. Results. Cox hazards regression revealed that both smoking and shortness in height independently contributed to total mortality and indicated that smoking as well as the presence of left ventricular hypertrophy predicted cardiovascular mortality. Our findings implicated that high AI, the presence of diabetes, and low high-density lipoprotein cholesterol were significant contributors to cardiovascular events. Conclusions. Our findings provide new evidence that shortness in height independently contributes to total mortality in hemodialysis patients
