Infected abdominal aortic aneurysm is uncommon, but it has a grave prognosis. We report a case of infected abdominal aortic aneurysm with localized dissection that was preoperatively given antibiotics for 1 month, followed by an anatomical vascular reconstruction with a prosthetic graft wrapped with a pedicled omental flap. A 48-year-old man with uncontrolled diabetis mellitus was admitted with fever, appetite loss, and pulsating abdominal pain. Abdominal CT revealed a saccular aneurysmal change in the infrarenal aorta and weakly enhanced surrounding soft tissue density. Two lumens were clearly enhanced in the aneurysm. Klebsiella pneumoniae infection was diagnosed on the basis of blood culture. Pathologically, suppurative inflammation was confirmed in the surrounding tissue and dissection of the media of the saccular aneurysmal wall was indicated. After administration of antibiotics for 1 month, both clinical and laboratory indications of inflammatory reaction improved. The aneurysm was then almost completely resected and replaced with a Y-shaped prosthetic graft covered with a pedicled omental flap. The postoperative course was uneventful. After surgery, antibiotics were administered for 3 more months. The patient is now surviving and has no symptoms 6 months after operaion. Complete removal of the infected lesion and long-term follow-up with antibiotic chemotherapy are important for this situation.

A 24-year-old woman with patent ductus arteriosus underwent division of the ductus. On the fifth postoperative day (POD 5), MRSA was detected in pus from the wound. On POD 8, an emergency operation was performed for left tension hemothorax due to a ruptured aorta with MRSA infection. The bleeding site in the descending aorta was covered with a viable omental flap under deep hypothermic circulatory arrest. Although MRSA was detected in the pleural effusion and the aortic wall, the patient recovered from pyothorax, and pneumonia caused by Pseudomonas aeruginosas and acute renal failure. On POD 37, a pseudoaneurysm of the descending aorta was found and graft replacement was performed on POD 56 due to enlargement of the aneurysm. However, MRSA was not detected in the left pleural effusion. The postoperative course was uneventful. Omental transfer should be considered for the treatment of severe aortic wall infection, even in the presense of MRSA infection.

The autonomic nervous system plays critical roles in maintaining homeostasis in humans, directly regulating inflammation by altering the activity of the immune system. The cholinergic anti-inflammatory pathway is a well-studied neuroimmune interaction involving the vagus nerve. CD4-positive T cells expressing β2 adrenergic receptors and macrophages expressing the alpha 7 subunit of the nicotinic acetylcholine receptor in the spleen receive neurotransmitters such as norepinephrine and acetylcholine and are key mediators of the cholinergic anti-inflammatory pathway. Recent studies have demonstrated that vagus nerve stimulation, ultrasound, and restraint stress elicit protective effects against renal ischemia-reperfusion injury. These protective effects are induced primarily via activation of the cholinergic anti-inflammatory pathway. In addition to these immunological roles, nervous systems are directly related to homeostasis of renal physiology. Whole-kidney three-dimensional visualization using the tissue clearing technique CUBIC (clear, unobstructed brain/body imaging cocktails and computational analysis) has illustrated that renal sympathetic nerves are primarily distributed around arteries in the kidneys and denervated after ischemia-reperfusion injury. In contrast, artificial renal sympathetic denervation has a protective effect against kidney disease progression in murine models. Further studies are needed to elucidate how neural networks are involved in progression of kidney disease.

Abstract
Introduction : There are few reports of long-term medical support activities in disaster areas. We analyzed drug-related data using medical records and prescriptions obtained during the long-term medical support of patients impacted by the Great East Japan Earthquake, which occurred on March 11, 2011.
Methods : Using medical records and prescriptions, the dispensing frequency of each drug was calculated and usage trends of the top three most frequently dispensed drugs are described here. All data was collected from March 26, 2011 onwards after the medical support activity commenced.
Results : In the first week of data acquisition, a total of 166 patients visited the medical support team (median 48.5, range 14-166). Following that, the number of patients decreased with a median of 24 people per day (range 0-47). The number of prescriptions for common cold medication was the highest, followed by antihypertensive and anti-allergic medications, respectively. The usage of antihypertensive drugs and common cold medications decreased over time, whereas anti-allergic medications were prescribed on a continuous basis.
Conclusion : Disaster medical support teams should not only be prepared to support the acute phase but also long-term phase, which depends heavily on the restoration of local medical services. The earlier the intervention to provide support, the greater the likelihood that the disaster medical support team will require to provide treatment for both acute and chronic illness.

OBJECTIVE: Schizophrenia is a mental disorder characterized by severe cognitive impairment. Accumulating evidence suggests a role for oxidative stress in the pathophysiology of schizophrenia. Sulforaphane (SFN) extracted from broccoli sprout is an agent with potent anti-oxidant and anti-inflammatory activity. In this study, we attempted to evaluate the effect of SFN on cognitive impairment in medicated patients with schizophrenia. METHODS: We recruited a total of 10 outpatients with schizophrenia, all of whom gave informed consent. Participants took 3 tablets of SFN, consisting of 30 mg of SFN-glucosinolate per day, for 8 weeks. Clinical symptoms using the Positive and Negative Syndrome Scale (PANSS) and cognitive function using the Japanese version of CogState battery were evaluated at the beginning of the study and at week 8. RESULTS: A total of 7 patients completed the trial. The mean score in the Accuracy component of the One Card Learning Task increased significantly after the trial. However, we detected no other significant changes in participants. CONCLUSION: This result suggests that SFN has the potential to improve cognitive function in patients with schizophrenia.

Objective: Caffeine may cause dependence and sleep disturbance, and interact with psychotropic drugs. Therefore, the caffeine intake of patients with mental disorders should be monitored. However, in Japan, there is no report on the effects of caffeine in mental disease patients or on their caffeine intake. Therefore, we conducted a questionnaire survey to clarify the perception of caffeine for psychiatric outpatients.Methods: We conducted an anonymous survey on caffeine recognition for outpatients at 8 medical institutions that advocate psychiatry.Results: We collected questionnaires from 180 people. The knowledge of foods containing caffeine tended to be high in those who had a positive attitude toward caffeine. More than 90% of those surveyed knew that coffee contains caffeine, but cocoa and jasmine tea were recognized by less than 25%. Of those surveyed, 39.4% consumed caffeine‐containing beverages at night. In addition, the rate of consumption of caffeine‐containing beverages tended to be higher at night because they had a positive attitude toward caffeine.Conclusion: The knowledge and intake situation of caffeine by patients with mental disorders differed depending on their interests and way of thinking about caffeine. As caffeine intake may influence psychiatric treatment, correct knowledge regarding caffeine is important.
