We set out to assess our treatment strategy of acute aortic dissection associated with atherosclerotic aortic aneurysm, and to assess its results. A total of 228 patients with acute aortic dissection were admitted to our hospital between 1994 and 2009. Among these, 30 cases were associated with atherosclerotic aortic aneurysm and we retrospectively analyzed their patient data. Of these, 5 patients received diagnoses of Stanford A dissection and 25 patients demonstrated Stanford B. Coexisting aneurysms consisted of postabdominal aortic replacement in 9 patients, ascending aortic aneurysm in 1, arch aortic aneurysm in 6, descending aortic aneurysm in 2, thoracoabdominal aortic aneurysm in 3, and abdominal aortic aneurysm in 9. Patients were divided into 3 groups based on the relationship between aneurysm and dissection : acute aortic dissection occurred after graft replacement of an aortic aneurysm (Group 1, n=9), dissection coexisted with aneurysm in a different segment of the aorta (Group 2, n=8), and dissection extended to or involved the aneurysm (Group 3, n=13). Our treatment strategy for all patients excluding those with aortic rupture or malperfusion is described below. In the cases of Stanford A dissection, emergency ascending aortic replacement or total arch replacement was performed. In cases of Stanford B, patients were treated conservatively in the acute phase. Surgery for the coexisting aortic aneurysm was then performed in the chronic phase, if the aneurysm was large. We think that the interval between dissection onset and aneurysm surgery should be extended to at least 1 month, because the aortic wall was too fragile to perform anastomosis in the acute phase in the present cases. As a result, there were 2 hospital deaths in Group 3, but there was no aortic rupture during treatment in the acute phase in any of these 3 groups. There were no vascular-related deaths during follow up. Our treatment strategy obtained favorable outcomes.

Syndromic craniosynostosis has severe cranial stenosis and deformity, combined with hypoplastic maxillary bone and other developmental skeletal lesions. Among these various lesions, upper air way obstruction by hypoplastic maxillary bone could be the first life-threatening condition after birth. Aggressive cranial vault expansion for severely deformed cranial vaults due to multiple synostoses is necessary even in infancy, to normalize the intracranial pressure. Fronto-orbital advancement (FOA) is recommended for patients with hypoplastic anterior part of cranium induced by bicoronal and/or metopic synostoses, and posterior cranial vault expansion is recommended for those with flattening of the posterior part of the cranium by lambdoid synostosis. Although sufficient spontaneous reshaping of the cranium can be expected by expansive cranioplasty, keeping the cranial bone flap expanded sufficiently is often difficult when the initial expansion is performed during infancy. So far distraction osteogenesis (DO) is the only method to make it possible and to provide low rates of re-expansion of the cranial vault. DO is quite beneficial for both FOA and posterior cranial vault expansion, compared with the conventional methods. Associated hydrocephalus and chronic tonsillar herniation due to lambdoid synostosis can be surgically treatable. Abnormal venous drainages from the intracranial space and air way obstruction should be always considered at any surgical procedures. Neurosurgeons have to know well about the managements not only of the deformed cranial vault and the associated brain lesions but also of other multiple skeletal lesions associated with syndromic craniosynostosis, to improve treatment outcome.

Endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) are essential for diagnosing and treating pancreatobiliary diseases. Single-session EUS and ERCP are considered to be essential in reducing the duration of hospital stays; however, complications are a primary concern. The aim of this study was to evaluate the safety and efficacy of single-session EUS and ERCP. Sixty-eight patients underwent single-session EUS and ERCP at a tertiary referral center between June 2008 and December 2012. We retrospectively reviewed patient data from a prospectively maintained EUS-ERCP database and evaluated the procedural characteristics and complications. Thirty-eight patients (56%) underwent diagnostic EUS, and 30 patients (44%) underwent EUS fine-needle aspiration, which had an overall accuracy of 100%. Sixty patients (89%) underwent therapeutic ERCP, whereas the remaining eight procedures were diagnostic. Thirteen patients underwent biliary stone extraction, and 48 underwent biliary drainage. The median total procedural time was 75 minutes. Complications were observed in seven patients (10%). Six complications were post-ERCP pancreatitis, which were resolved using conservative management. One patient developed Mallory-Weiss syndrome, which required endoscopic hemostasis. No sedation-related cardiopulmonary complications were observed. Single-session EUS and ERCP provided accurate diagnosis and effective management with a minimal complication rate.

Herein, we report a case of a 49-year-old man with a history of bilateral hemiplegia caused by severe traumatic brain injury. During his stay in the convalescent rehabilitation hospital, he developed a flexion deformity of the 4th and 5th fingers of his right hand. Elbow palpation and ultrasonography showed that the ulnar nerve was dislocated from the elbow canal, and a nerve conduction study revealed that the conduction velocity was low in the right elbow. Thus, a diagnosis of cubital tunnel syndrome was made and an ulnar nerve transfer was performed to prevent progression. Prior to onset, an over-table had been used by the patient for daily activities such as sitting, training, and eating. Therefore, it was considered that the repeated use of the over-table plausibly exerted pressure on the dislocated ulnar nerve, leading to the onset of the cubital tunnel syndrome.As over-tables and wheelchair armrests are often used during rehabilitation, it is imperative to pay attention to elbow compression when using them in patients with ulnar nerve dislocation.

A premature boy was born after 35 weeks gestation (1,561 g in weight) with a diagnosis of anomalous origin of the right pulmonary artery from the ascending aorta (AORPA) and perimembranous ventricular septal defect (VSD). The fourteenth day after birth, banding of the right pulmonary artery was performed as a palliative operation. At the age of 5 months (3.9 kg in weight), the right pulmonary artery branched from the ascending aorta, and was anastomosed to a flap made by the lateral wall of the main pulmonary artery with pericardial patch augmentation. VSD patch closure was performed concomitantly. Severe stenosis of the right pulmonary artery compressed by the ascending aorta and left pulmonary hypertension were revealed 3 weeks after the repair. At the age of 11 months, a surgical relief of the right pulmonary artery stenosis was performed. Transection of the ascending aorta provided an excellent exposure of the right posterior pulmonary artery. After patch plasty of the stenotic pulmonary artery, the divided ascending aorta was restored using a strip form patch on 4/5 circle of its posterior wall to extend the aorta and widen the space for the right pulmonary artery. This technique preserves growth potential of the ascending aorta. There are few reports of surgical repair of AORPA with VSD in low birth weight infants. We presented here a case with surgical relief of post-operative right pulmonary artery stenosis. Long term observation of repaired right pulmonary artery, and requiring residual slight hypertension of the left pulmonary artery.

BACKGROUND/AIMS: Although the risk of bleeding after endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is low, the safety of EUS-FNA in patients prescribed antithrom-botic agents is unclear. Therefore, this study evaluated the incidence of bleeding after EUS-FNA in those patients. METHODS: Between September 2012 and September 2015, patients who were prescribed antithrombotic agents underwent EUS-FNA at 13 institutions in Japan were prospectively enrolled in the study. The antithrombotic agents were managed according to the guidelines of the Japanese Gastrointestinal Endoscopy Society. The rate of bleeding events, thromboembolic events and other complications within 2 weeks after EUS-FNA were analyzed. RESULTS: Of the 2,629 patients who underwent EUS-FNA during the study period, 85 (62 males; median age, 74 years) patients were included in this stduy. Two patients (2.4%; 95% confidence interval [CI], 0.6% to 8.3%) experienced bleeding events. One patient required surgical intervention for hemothorax 5 hours after EUS-FNA, and the other experienced melena 8 days after EUS-FNA and required red blood cell transfusions. No thromboembolic events occurred (0%; 95% CI, 0.0% to 4.4%). Three patients (3.5%; 95% CI, 1.2% to 10.0%) experienced peri-puncture abscess formation. CONCLUSIONS: The rate of bleeding after EUS-FNA in patients prescribed antithrombotic agents might be considerable.

At Anjo Kosei Hospital, all staff has been working concertedly on a project to establish a community hospital in line with our future vision. Hospital staff in charge of the Medical Affairs Division has been involved in measures aimed at achieving the slogan “health and happiness of local residents” as part of this project. To address this, three goals were set as follows: improvement of recoveries in accounts receivable management, a reduction of money held in trust, and a decrease in the number of outsourced transactions. To achieve the goals described above, the following specific measure were carried out: (1) collection of accounts receivable using convenience store settlement; (2) collection of high-cost medical expenses by wider use of Eligibility Certificates for Ceiling-Amount Applications and promotion of the Major Medical Cost Loan System for national health insurance holders; and (3) support in acquiring family registration for nonregistered family members and for health insurance benefits. Recoveries of accounts receivable through convenience store settlement was about 90,000 yen/month, and our support activities for family registration and health insurance benefits provided the recoveries of about 80,000 yen/month. Furthermore, the promoted use of the certificate and loan system resulted in recoveries of about 17 million yen/year. The average commission fee and number of outsourcing was 890,188 yen and 12 cases, respectively, from April to August 2016. However, in 2017, it was 305,615 yen and 10 cases, respectively. Our project aimed at achieving slogan-elicited patient voluntary payment of medical expenses, leading to improved recoveries, with reduced money held in trust and fewer outsourced transactions.
