A 16-year-old girl with aortitis syndrome under treatment with a low dose of prednisolone was admitted because of severe headache and intermittent claudication. Angiography revealed diffuse stenosis of the thoracoabdominal aorta and the bilateral renal arteries. Extra-anatomical bypass grafting from the ascending to the abdominal aorta was first made with a 14mm woven Dacron graft through a midline sternolaparotomy. Bilateral renal arteries were difficult to dissect due to periarterial adhesion. Bypass grafting for the left renal artery could be performed with a 5mm external velour wrap-knit Dacron graft (Sauvage, Bionit); however, the right renal artery was so thin that bypass was made with a 4mm EPTFE graft which was demonstrated to be occluded by follow-up angiography 3 years after surgery. The postoperative course has been uneventful and she has been free from symptoms up to now. The good long-term function of the bypass graft from the ascending aorta holds promise for diffuse coarctation of the thoracoabdominal aorta due to aortitis syndrome.

The left atrium and left atrial appendage have unique genetic anatomical and physiological features. Recently, advances in diagnostic imaging technology have provided much new knowledge. Clinically, the risk of developing atrial fibrillation increases with age. In order to reduce the public health burden such as cerebral infarction caused by atrial fibrillation, we need to find some predictive risk factors and preventive strategies for cerebral infarction and more effective treatments. The new concept of atrial myopathy has emerged, and animal models and human studies have revealed close interactions between atrial myopathy, atrial fibrillation, and stroke through various mechanisms. Structural and electrical remodeling such as fibrosis and deterioration of the balance of autonomic nerves and complicated interactions between these mechanisms lead to deterioration of atrial fibrillation and a continuous vicious cycle, and finally thrombosis in the left atrial appendage. Although anticoagulant therapy for patients with atrial fibrillation is strongly recommended, it is difficult for many patients to continue optimal treatment. In the nearly future, it will be important to understand the anatomy and physiology of the left atrial appendage and to understand the shape changes, size and the changes of autonomic function, and thrombus formation conditions associated with LAA remodeling during atrial fibrillation, and then we should provide early therapeutic intervention.

We evaluated the surgical strategy for thoracic aortic aneurysm associated with abdominal aortic aneurysm. From January 1982 to March 1999, 24 consecutive patients underwent surgical treatment for thoracic aortic aneurysm with abdominal aortic aneurysm. Staged operation was performed if one was only slightly dilated, but extensive operation was needed if the size of both aneurysms was greater than 6cm. In cases of thoracic aortic aneurysm with abdominal aortic aneurysm up to 4cm in size, surgical treatment was performed only for the thoracic aortic aneurysm. Circulatory support during operation was established from the ascending aorta, and circulatory arrest with deep hypothermia and retrograde cerebral perfusion were used for brain protection during surgery for thoracic aortic arch aneurysm. Hospital mortality was 12.5% (3/24 cases). The causes of death were cerebral infarction and respiratory failure. Antegrade systemic perfusion and aortic no-touch technique were an effective method of surgery for thoracic aortic aneurysm with abdominal aortic aneurysm to avoid perioperative embolism and major complications. We successfully performed staged operation, but regular radiographic follow-up was needed.

Background/Aims:
Although risk factors of reflux esophagitis (RE) have been investigated in numerous cross-sectional studies, little is known about predictive factors associated with future onset of RE. We investigated time courses of clinical parameters before RE onset by a longitudinal case-control study using health checkup records.
Methods:
We used health checkup records between April 2004 and March 2014 at 9 institutions in Japan. A multivariate logistic regression analysis was performed to evaluate associations of baseline clinical parameters with RE. The time courses of the clinical parameters of RE subjects were compared with those of non-RE subjects by the mixed-effects models for repeated measures analysis or longitudinal multivariate logistic analysis.
Results:
Initial data were obtained from 230 056 individuals, and 2066 RE subjects and 4132 non-RE subjects were finally included in the analysis. Body mass index, alanine aminotransferase, smoking, acid reflux symptoms, hiatal hernia, and absence of atrophic gastritis at baseline were independently associated with RE. The time courses of body mass index, fasting blood sugar, triglyceride, aspartate aminotransferase, alanine aminotransferase, γ-glutamyl transpeptidase, percentages of acid reflux symptoms, feeling of fullness, and hiatal hernia in the RE group were significantly worse than in the non-RE group.
Conclusions
The RE group displayed a greater worsening of the clinical parameters associated with lifestyle diseases, including obesity, diabetes, hyperlipidemia, and fatty liver for 5 years before RE onset compared with the non-RE group. These results suggest that RE is a lifestyle disease and thus lifestyle guidance to at-risk person may help to prevent RE onset.

Introduction: Since the commercial availability of buprenorphine extended-release transdermal patches (BTDP) from the early 2010’s, the therapeutic indications for opioids have widely expanded to include chronic benign diseases. We report a case of a home health care patient with acute opioid withdrawal symptoms due to self-interruption of BTDP. Case: An 84-year-old man using home health care services due to worsening of lumbar spinal canal stenosis had been receiving analgesia with a BTDP, a mixed opioid agonist/antagonist analgesic, for the preceding five months. Since the patient's spouse thought that his pain and symptoms were gradually improving, she secretly replaced the BTDP with an NSAID patch without informing the patient. About 50 hours later, the patient experienced a variety of symptoms, including frequent urination with incontinence every five minutes, watery diarrhea, sweating, decreased blood pressure, discomfort in the feet, and insomnia. Evaluation of the Clinical Opiate Withdrawal Score (COWS) by the home health care physician indicated a score of 12, corresponding to mild withdrawal symptoms. About 12 hours after symptom onset, the severe abnormalities were barely noticeable and completely disappeared after two days. Conclusion: Few previous case reports have described withdrawal symptoms due to rapid discontinuation of BTDP. In addition to the medical considerations, we report the social issues associated with onset of the condition in a home environment. Opioid use for non-cancer pain requires medication management from a different perspective than that for cancer pain.

The Japanese Society of Hepato-Biliary-Pancreatic Surgery launched the clinical practice guidelines for the management of biliary tract cancers (cholangiocarcinoma, gallbladder cancer, and ampullary cancer) in 2007, then published the 2nd version in 2014. In this 3rd version, clinical questions (CQs) were proposed on six topics. The recommendation, grade for recommendation, and statement for each CQ were discussed and finalized by an evidence-based approach. Recommendations were graded as grade 1 (strong) or grade 2 (weak) according to the concepts of the grading of recommendations assessment, development, and evaluation system. The 31 CQs covered the six topics: (1) prophylactic treatment, (2) diagnosis, (3) biliary drainage, (4) surgical treatment, (5) chemotherapy, and (6) radiation therapy. In the 31 CQs, 14 recommendations were rated strong and 14 recommendations weak. The remaining three CQs had no recommendation. Each CQ includes a statement of how the recommendations were graded. This latest guideline provides recommendations for important clinical aspects based on evidence. Future collaboration with the cancer registry will be key for assessing the guidelines and establishing new evidence.

A 66-year-old man was admitted to our intensive care unit because of severe pneumonia. He was treated with mechanical ventilation, antibiotics, and corticosteroids, but muscle weakness developed rapidly. His muscle strength declined to a Medical Research Council scale sum score of 18/60;thus, a diagnosis of intensive care unit-acquired weakness (ICU-AW) was made. The results of nerve conduction studies were compatible with critical illness polyneuropathy. Mechanical ventilation was required for 95 days because of continuous respiratory failure. Rehabilitation began at 48 hours after hospitalization and was continued to prevent immobilization even when he was mechanically ventilated. However, orthostatic hypotension developed and inhibited mobility training. Physical and occupational therapies provided muscle strengthening exercises followed by a progressive mobility program that assisted him to raise his head, sit on the edge of the bed, and stand up. The intervention was performed within safety criteria of vital signs and the rating of perceived exertion (RPE) Borg scale between 11 and 13. It resulted in the attenuation of orthostatic hypotension and the recovery of muscle strength. He finally achieved independence in activities of daily living and the ability to walk without help after 271 days of admission. This case report suggests that long-term rehabilitation within safety criteria of vital signs and RPE Borg scale between 11 and 13 is safe and feasible without overuse weakness for ICU-AW with orthostatic hypotension.
