Objective We started an information technology (IT) system that encodes the medical treatment status of hepatitis B virrus (HBV) with a 9-digit number, automatically checks for inappropriate situations occurring due to immunosuppression and chemotherapy that do not comply with the flowchart of the hepatitis B countermeasure guideline, and promotes correct HBV medical treatment in our hospital. We conducted a prospective study of HBV reactivation using this system. Methods Among 21,607 cases that were managed using this system, 1,206 patients who were HBs antigen-negative, HBc antibody- and/or HBs antibody-positive and in whom HBV DNA quantification was performed two times or more were examined for the occurrence of HBV reactivation. ⋯ Conclusion Continuing of the operation of an automatic check system using coded medical information to check for the reactivation enabled this prospective study of HBV reactivation. Careful attention should be paid to patients using steroids, as well as malignant lymphoma patients who are treated with rituximab. The results of the present study suggest that the present IT encoding system would be useful for preventing HBV reactivation.

Objective In the medical treatment of Graves' disease, we sometimes encounter patients who gain weight after the onset of the disease. To estimate the energy required during the course of treatment when hyperthyroidism ameliorates, we measured the resting energy expenditure (REE) and body composition in patients with Graves' disease before and during treatment in the short-term. Methods Twenty patients with newly diagnosed Graves' disease were enrolled, and our REE data of 19 healthy volunteers were used. ⋯ The decline was evident as early as one month after treatment. The REE after treatment was lower than in healthy volunteers, which may lead to weight gain. These data suggest that appropriate nutritional guidance is necessary with short-term treatment before the body weight normalizes in order to prevent an overweight condition and the emergence of metabolic disorders.

Case Reports
Anti-leucine-rich Glioma Inactivated-1 Encephalitis Associated with Essential Thrombocythemia.
Anti-leucine-rich glioma inactivated-1 (anti-LGI1) encephalitis is a subgroup of autoimmune encephalitis. We herein report the case of a 60-year-old man who presented with typical symptoms, including short-term memory loss, mental abnormalities, hyponatremia and seizures characterized by faciobrachial dystonic seizures and who was diagnosed with anti-LGI1 encephalitis. ⋯ A significant improvement was obtained by treatment with corticosteroid, immunoglobulin, mycophenolate mofetil, and hydroxyurea. Autoimmune diseases are associated with a significantly increased risk of developing myeloproliferative neoplasms, which may explain the coexistence of anti-LGI1 encephalitis and essential thrombocythema in this patient; however, but more cases and studies are needed to determine whether there is any correlation between these conditions.

Objective Associations between aortic stiffness and cardiovascular disease events are mediated in part by pathways that include coronary microvascular dysfunction (CMD) and remodeling. However, the relationship between aortic stiffness and CMD remains unclear. The present study aimed to determine whether aortic stiffness causes CMD as evaluated by the hyperemic microvascular resistance index (hMVRI) in patients with non-obstructive coronary artery disease (CAD). ⋯ A multivariate regression analysis identified CAVI (β=0.25, p=0.007) and EPA/AA ratio (β=-0.26, SE=0.211, p=0.003) as independent determinants of hMVRI. Conclusion Aortic stiffness may cause CMD in patients with non-obstructive CAD via increased coronary microvascular resistance. Aortic stiffness is associated with CMD which is evaluated as hyperemic microvascular resistance in patients with non-obstructive CAD.

Case Reports
Idiopathic Orbital Inflammation Appearing on the Affected Side of Preceding Myasthenia Gravis.
The patient was a 70-year-old man with idiopathic orbital inflammation (IOI) that appeared on the severely affected side of preceding myasthenia gravis (MG). The patient was diagnosed with MG 5 years prior to the onset of IOI. When IOI was diagnosed, an edrophonium test was negative. ⋯ A biopsy specimen revealed pathological findings compatible with IOI. The administration of corticosteroids was effective for improving the ocular symptoms. IOI should be considered when ocular symptoms deteriorated with soft tissue swelling/pain in MG patients.
