Hyperglycemic Hyperosmolar Syndrome Caused by Steroid Therapy in a Patient with Lupus Nephritis
A 51-yr-old female was referred to our outpatient clinic for the evaluation of generalized edema. She had been diagnosed with idiopathic thrombocytopenic purpura (ITP). She had taken no medicine. Except for the ITP, she had no history of systemic disease. She was diagnosed with systemic lupus erythematosus. Immunosuppressions consisting of high-dose steroid were started. When preparing the patient for discharge, a generalized myoclonic seizure occurred at the 47th day of admission. At that time, the laboratory and neurology studies showed hyperglycemic hyperosmolar syndrome. Brain MRI and EEG showed brain atrophy without other lesion. The seizure stopped after the blood sugar and serum osmolarity declined below the upper normal limit. The patient became asymptomatic and she was discharged 10 weeks after admission under maintenance therapy with prednisolone, insulin glargine and nateglinide. The patient remained asymptomatic under maintenance therapy with deflazacort and without insulin or medication for blood sugar control

Changes in Renal Function after Different Tandem Hematopoietic Stem-cell Transplantation Approaches in Patients with Multiple Myeloma
This study was done to observe the alteration of the estimated glomerular filtration rate (eGFR) in multiple myeloma patients according to type of tandem hematopoietic stem cell transplantation (HSCT). Forty-one patients were enrolled in this study. Twenty patients underwent autologous HSCT (auto-HSCT) and 21 patients underwent allogeneic HSCT (allo-HSCT). The changes in eGFR after the two tandem HSCT modalities were different between the two groups, according to the donor of stem cells (P = 0.016). In the auto-HSCT group, the eGFR, recorded 12 months after secondary HSCT, was significantly decreased compared with the eGFR recorded before stem cell mobilization (P = 0.005). Although there was no significant difference, the trend showed that the eGFR after allo-HSCT decreased from the previous HSCT until a month after secondary HSCT. In addition, after 6 months of secondary HSCT, the eGFR recovered to the level recorded prior to the HSCT (P = 0.062). This difference may be due to total body irradiation, a calcineurin inhibitor, or maintemance therapy. Changes in renal function would be monitored closely for these patients. The recovery of the eGFR would be a main focus for the patients treated with the total body irradiation or the calcineurin inhibitor, a progressive decline of the eGFR would be also crucial for the patients treated with maintenance therapy
Prediction of clinical outcomes after kidney transplantation from deceased donors with acute kidney injury: a comparison of the KDIGO and AKIN criteria
Combined Transfibular and Anterior Approaches Increase Union Rate and Decrease Non-Weight-Bearing Periods in Ankle Arthrodesis: Combined Approaches in Ankle Arthrodesis
The transfibular approach is a widely used method in ankle arthrodesis. However, it is difficult to correct coronal plane deformity. Moreover, it carries a risk of nonunion and requires long periods of non-weight-bearing because of its relatively weak stability. We hypothesized that the transfibular approach combined with the anterior approach in ankle arthrodesis wound yield a higher fusion rate and shorter non-weight-bearing period. This study was performed to evaluate the clinical and radiographic results and postoperative complications in ankle arthrodesis using combined transfibular and anterior approaches in end-stage ankle arthritis. Thirty-five patients (36 ankles) with end-stage ankle arthritis were consecutively treated using ankle arthrodesis by combined transfibular and anterior approaches. The subjects were 15 men and 20 women, with a mean age of 66.5 years (46–87). Clinical results were assessed using the visual analog scale (VAS) for pain, the American Orthopaedic Foot and Ankle Society (AOFAS) scores, and the ankle osteoarthritis scale (AOS) preoperatively and at the last follow-up. Radiographic results were assessed with various radiographic parameters on ankle weight-bearing radiographs and hindfoot alignment radiographs. All clinical scores significantly improved after surgery. Union was obtained in all cases without additional surgery. Talus center migration (p = 0.001), sagittal talar migration (p < 0.001), and hindfoot alignment angle (p = 0.001) significantly improved after surgery. One partial skin necrosis, two screw penetrations of the talonavicular joint, and four anterior impingements because of the bulky anterior plate occurred after surgery. In conclusion, combined transfibular and anterior approaches could be a good method to increase the union rate and decrease the non-weight-bearing periods in ankle arthrodesis
Severe but reversible acute kidney injury resulting from Amanita punctata poisoning
Mushroom-related poisoning can cause acute kidney injury. Here we report a case of acute kidney injury after ingestion of Amanita punctata, which is considered an edible mushroom. Gastrointestinal symptoms occurred within 24 hours from the mushroom intake and were followed by an asymptomatic period, acute kidney injury, and elevation of liver and pancreatic enzymes. Kidney function recovered with supportive care. Nephrotoxic mushroom poisoning should be considered as a cause of acute kidney injury
Controller Design and Experiment for Tracking Mount of Movable SLR, ARGO-M
Controller design procedure for prototype tracking mount of Movable SLR (Satellite Laser Ranging), ARGO-M is presented. Tracking mount of ARGO-M is altitude-azimuth type and it has two axes of elevation and azimuth to control its position. Controller consists of velocity and acceleration feed-forward controller, position controller at outer loop, velocity controller at inner loop. There are two kinds of position control modes. One is the pointing mode to move from one position to the other position as fast as possible and the other one is tracking mode to follow SLR trajectory as precise as possible. Because the requirement of tracking accuracy is less than 5 arcsec and it is very tight error budget, a sophisticated controller needs to be prepared to meet the accuracy. Especially, ARGO-M is using the cross-roller bearing at each axis to increase the mechanical accuracy, which requires add-on controller DOB (Disturbance observer) to suppress friction load and low frequency disturbances. The pointing and tracking performance of the designed controller is simulated and visualized using MATLAB/ Simulink and SimMechanics and the experimental results using test are presented as well
