Despite the development of radiotherapy machines and technologies, a proportion of patients suffer from radiation-induced enteritis or oral mucositis. It has been reported that hangeshashinto has been used for not only enteritis but also oral mucositis. This study reports the effect of hangeshashinto on enteritis or oral mucositis caused by radiotherapy. Three patients with enteritis and 5 patients with oral mucositis were treated with hangeshashinto at a dose of 7.5 g/day. The severity of enteritis or oral mucositis was evaluated using the Common Terminology Criteria for Adverse Events version 4 and Numerical Rating Scale both before and after hangeshashinto treatment. After the treatment with hangeshashinto, 3 of 5 patients with oral mucositis and 2 of 3 patients with enteritis showed apparent improvement. In conclusion, it is important to control the side effects of radiotherapy, which lead to improved tumor control rates. Prospective randomized studies are necessary to confirm the findings of this case series study.

OBJECTIVES: This article describes the Web application framework for Electronic Health Records (EHRs) we have developed to reduce construction costs for EHR sytems. METHODS: The openEHR project has developed clinical model driven architecture for future-proof interoperable EHR systems. This project provides the specifications to standardize clinical domain model implementations, upon which the ISO/CEN 13606 standards are based. The reference implementation has been formally described in Eiffel. Moreover C# and Java implementations have been developed as reference. While scripting languages had been more popular because of their higher efficiency and faster development in recent years, they had not been involved in the openEHR implementations. From 2007, we have used the Ruby language and Ruby on Rails (RoR) as an agile development platform to implement EHR systems, which is in conformity with the openEHR specifications. RESULTS: We implemented almost all of the specifications, the Archetype Definition Language parser, and RoR scaffold generator from archetype. Although some problems have emerged, most of them have been resolved. CONCLUSIONS: We have provided an agile EHR Web framework, which can build up Web systems from archetype models using RoR. The feasibility of the archetype model to provide semantic interoperability of EHRs has been demonstrated and we have verified that that it is suitable for the construction of EHR systems.

A 55-year-old man visited his neighborhood general practitioner complaining of headache, fever and wet cough on July 7, 2003, but there were no sigins that his symptoms would subside. Since an abnormal shadow was found on chest X-ray on July 11, he was referred to our department and hospitalized on the same day. We started to treat him on the assumption that he had community-acquired pneumonia due-to common pathogens. However, he developed severe hypoxemia, and abnormal shadows rapidly progressed to affect both lungs, which led us to suspect that he had acute respiratory distress syndrome (ARDS). We identified the pathogen by examining urinary antigens and serum antibodies and diagnosed of his case as Legionella pneumonia. Although he suffered complications of acute renal failure and shock, the respirator was withdrawn after 11 days of controlled mechanical ventilation, as he was steadily recovering from his illness. The patient was discharged from the hospital on September 9. Although the mortality of legionella pneumonia, when complicated by ARDS, acute renal failure and shock as in the present case, has been reported to be as high as 50 to 80%, we consider that the administration of neutrophil elastase inhibitors and steroids was effective against this disorder.

To test the hypothesis that neutrophils play a role in lung injury during cardiopulmonary bypass, granulocyte elastase and myeloperoxidase release from pulmonary circulation were measured, as well as the respiratory index, before and after cardiopulmonary bypass. The production of granulocyte elastase and myeloperoxidase in the pulmonary circulation, and the respiratory index also elevated significantly after cardiopulmonary bypass. Furthermore, the level of granulocyte elastase and myeloperoxidase released from pulmonary circulation correlated with the changes of the respiratory index and preoperative pulmonary artery pressure. These data indicate that neutrophils play a major role in pulmonary dysfunction occurring after cardiopulmonary bypass, which is accentuated in patients with pulmonary hypertension.

PURPOSE: The purpose of this study was to evaluate the morphology of the mandibular cortex in cases of medication-related osteonecrosis of the jaw (MRONJ) in patients with osteoporosis or bone metastases using a computer programme.MATERIALS AND METHODS: Fifty-four patients with MRONJ (35 with osteoporosis and 19 with bone metastases) were examined using panoramic radiography. The morphology of the mandibular cortex was evaluated using a computer programme that scanned the mandibular inferior cortex and automatically assessed the mandibular cortical index (MCI) according to the thickness and roughness of the mandibular cortex, as follows: normal (class 1), mildly to moderately eroded (class 2), or severely eroded (class 3). The MCI classifications of MRONJ patients with osteoporosis or bone metastases were evaluated with the Pearson chi-square test. In these analyses, a 5% significance level was used.RESULTS: The MCI of MRONJ patients with osteoporosis (class 1: 6, class 2: 15, class 3: 14) tended to be higher than that of patients with bone metastases (class 1: 14, class 2: 5, class 3: 0) (P=0.000).CONCLUSION: The use of a computer programme to assess mandibular cortex morphology may be an effective technique for the objective and quantitative evaluation of the MCI in MRONJ patients with osteoporosis or bone metastases.

A 14-year-old women who had a history of aortic root replacement at 7 years old admitted our hospital due to dilatation of aortic arch aneurysm. Loeys-Dietz syndrome was diagnosed when she was 10 years old. Computed tomography showed 70 mm proximal arch aneurysm. Operative findings revealed brachiocephalic artery and left common carotid artery branched from aneurysm. Partial arch replacement was performed and distal anastomosis was made between left common carotid artery and left subclavian artery. Close observation by CT regularly is necessary and undergo aortic repair not to miss the timing of surgery.
