We report a rare case of paraplegia after emergency total arch replacement for type A acute aortic dissection. A 52-year-old man was referred to our hospital for acute aortic dissection. Contrast-enhanced computed tomography showed a type A aortic dissection extending from the aortic root into the right iliac arteries. The true lumen of the descending and abdominal aorta was collapsed and blood flow to the right lower limb had decreased. Large entry and re-entry tears were revealed in the ascending and distal arch aorta, respectively. His preoperative consciousness was clear, hemodynamics were stable, and there was no evidence of paraplegia or paraparesis. Extracorporeal circulation was established by femoral artery and right atrium cannulation. Total arch replacement was performed under moderate hypothermic circulatory arrest (lowest bladder temperature : 21.9°C). The postoperative course was uneventful and he was extubated 6 h postoperatively. Postoperative hemodynamic parameters were stable, the mean blood pressure was maintained at around 70 mmHg, and limb movements were confirmed at that time. Although there was no abnormality of lower limb movement until the following morning, paraplegia occurred about 17 h after surgery. While maintaining a mean blood pressure of over 90 mmHg, urgent cerebrospinal drainage was immediately performed and combined with steroid treatment and a continuous infusion of naloxone. The neurological defect was resolved immediately after cerebrospinal drainage, and neurological function steadily improved through rehabilitation. He was discharged 20 days after surgery with no neurological defects. Late paraplegia after total replacement for type A acute aortic dissection is a rare complication. From our experience, it is suggested that early diagnosis and treatment are important for improving paraplegia.

Infective endocarditis of the aortic valve tends to cause structural damage such as aortic root abscess, and aortic valve replacement is the standard treatment. However, there have been several reports on aortic valve repair for the treatment of infective endocarditis, and it has subsequently emerged as a feasible alternative to aortic valve replacement in selected patients. We report a case of aortic valve repair for infective endocarditis of the aortic valve caused by α-hemolytic Streptococcus. A 50-year-old man was admitted to our hospital with a two-month history of fever of unidentified origin. Transthoracic echocardiography revealed infective endocarditis of the aortic valve. Transesophageal echocardiography confirmed vegetation in the right coronary and non-coronary cusps, and mild aortic regurgitation. Although infection was controlled by approximately one month of antibiotic treatment, there was markedly more severe aortic regurgitation compared to the previous examination. These findings were confirmed on transesophageal echocardiography, and residual vegetation on the right coronary cusp as well as a perforation in the non-coronary cusp were confirmed. Intraoperative findings revealed a perforation in the non-coronary cusp and dehiscence, with vegetation on the right coronary cusp. The vegetation was carefully removed, the non-coronary cusp perforation was repaired with a pericardium patch, and the defect on the right coronary cusp was directly sutured with 6-0 polypropylene. Intraoperative transesophageal echocardiography revealed trivial aortic regurgitation. The postoperative course was uneventful and the patient was discharged 7 days after surgery without any complications. Antibiotics were prescribed for 3 months, and transthoracic echocardiography was performed 5 days, 1 month, and 3 months after surgery. No evidence of recurrence of aortic regurgitation or infection of the aortic valve was observed.

Reoperative valve surgery is known to be more complex and associated with increased morbidity and mortality, especially for patients with patent coronary artery bypass grafts. A 69-year old man with a history of coronary artery bypass grafting was referred to our hospital with breathing difficulties and a heart murmur. Bypass grafts were all patent, but due to severe ischemic mitral valve regurgitation, we performed beating heart mitral valve replacement via right thoracotomy. The procedure was performed with video assistance, and both the anterior and the posterior chordae tendineae were preserved. The postoperative course was uneventful. He was discharged 7 days after surgery without any complications. This technique is a safe and feasible option for a mitral valve reoperation that avoids graft injuries, minimizes the risks of bleeding, and shortens the operative time.

Objective:
To investigate the effect on early mobilization in patients undergoing extra-corporeal membrane oxygenation (ECMO) and acute blood purification therapy in the intensive care unit (ICU).
Methods:
We conducted this multicenter retrospective cohort study by collecting data from six ICUs in Japan. Consecutive patients who were admitted to the ICU, aged ≥18 years, and received mechanical ventilation for >48 hours were eligible. The analyzed were divided into two groups: ECMO/blood purification or control group. Clinical outcomes; time to first mobilization, number of total ICU rehabilitations, mean and highest ICU mobility scale (IMS); and daily barrier changes were also investigated.
Results:
A total of 204 patients were included in the analysis, 43 in the ECMO/blood purification group and 161 in the control group. In comparison of clinical outcome, the ECMO/blood purification group had a significantly longer time to first mobilization: ECMO/blood purification group 6 vs. control group 4 (p=0.003), higher number of total ICU rehabilitations: 6 vs. 5 (p=0.042), lower mean: 0 vs. 1 (p=0.043) and highest IMS: 2 vs. 3 (p=0.039) during ICU stay. Circulatory factor were most frequently described as barriers to early mobilization on days 1 (51%), 2 (47%), and 3 (26%). On days 4 to 7, the most frequently described barrier was consciousness factors (21%, 16%, 19%, and 21%, respectively)
Conclusion
The results of this study comparing the ECMO/blood purification group and the untreated group in the ICU showed that the ECMO/blood purification group had significantly longer days to mobilization and significantly lower mean and highest IMS.

In this report, we present a case of successful treatment of a bowel fistula in the open abdomen by perforator flaps and an aponeurosis plug. A 70-year-old man underwent total gastrectomy and developed anastomotic leakage and dehiscence of the abdominal wound a week later. He was dependent upon extracorporeal membrane oxygenation, continuous hemodiafiltration, and a respirator. Bowel fluids contaminated the open abdomen. Two months after the gastric operation, a plastic surgery team, in consultation with general surgeons, performed perforator flaps on both sides and constructed, as it were, a bridge of skin sealing the orifice of the fistula. The aponeurosis of the external oblique muscle was elevated with the flap to be used as a plug. The perforators of the flaps were identified on preoperative and intraoperative ultrasonography. This modality allowed us to locate the perforators precisely and to evaluate the perforators by assessing their diameters and performing a waveform analysis. The contamination decreased dramatically afterwards. The bare areas were gradually covered by skin grafts. The fistula was closed completely 18 days after the perforator flap. An ultrasoundguided perforator flap with an aponeurosis plug can be an option for patients suffering from an open abdomen with a bowel fistula.

BACKGROUND/AIMS: To confirm the feasibility of using newly developed endoscopic ultrasound (EUS) with Zone sonography(TM) technology (ZST; Fujifilm Corp.). METHODS: Seventy-five patients with pancreatic disorders were enrolled: 45 with intraductal papillary mucinous neoplasm; 15 with ductal carcinoma; five with neuroendocrine tumors; three with serous cystic neoplasms; and seven with simple cysts. The endoscopes used were EG-530UR2 and EG-530UT2 (Fujifilm Corp.). Two items were evaluated: visualization depth among four frequencies and image quality after automatic adjustment of sound speed (AASS), assessed using a 5-scale Likert scale by two endosonographers blinded to disease status. Because sound speed could be manually controlled, besides AASS, image quality at sound speeds of 1,440 and 1,600 m/sec were also assessed. RESULTS: In all cases, sufficient images were obtained in the range of 3 cm from the EUS probe. Judgments of image quality before AASS were 3.49+/-0.50, 3.65+/-0.48, respectively. After AASS, A and B scored 4.36+/-0.48 and 4.40+/-0.49 (p<0.0001). There were significant differences in the data before and after AASS and plus 60 m/sec, but no significant difference between the datasets were seen after AASS and at sound speeds manually set for minus 100 m/sec. CONCLUSIONS: EUS with ZST was shown to be feasible in this preliminary experiment. Further evaluation of this novel technology is necessary and awaited.

Objective To identify issues in health communication regarding treatment support for foreign-born who are diagnosed as latent tuberculosis infection (LTBI) in Japan, from the perspective of public health centers (PHCs).Methods A self-administered survey was sent to 469 PHC, between June and July 2020. The survey asked closed and open-ended questions to tuberculosis (TB) program personnel on (1) their experiences of foreign-born patients who were eligible for LTBI treatment but did not start their treatment, and who started treatment but were lost to follow-up, and (2) health communication issues with foreign-born patients. Responses were summarized descriptively for close-ended questions, and analyzed qualitatively for open-ended question.Results We obtained response from 307 PHCs, regarding 315 foreign-born patients. Twenty-five patients did not initiate, and 52 were lost to follow-up after initiating LTBI treatment. Of the 77 patients who either did not start treatment or were lost to follow-up, 45 apparently could hold everyday conversation in Japanese but had difficulties understanding technical terms, and 19 could not even exchange basic conversation, with PHC staff. Barriers to LTBI treatment initiation and completement, as perceived by PHC staff, included “lack of correct knowledge about TB and LTBI”, “different attitudes to health” and “economic difficulties”. Conclusion Issues in health communication between PHC staff and foreign-born patients included not only a language barrier, but also the unconscious mind among PHC staff, which sought reasons for refusal or termination of LTBI treatment in patients. We argue that this mind is based on positivism, whereby health personnel consider themselves as the provider of “scientific knowledge” and that “lay persons” can act rationally once enlightened. However, PHC staff may need to reflect upon such position as the provider of scientific knowledge, but instead, learn from foreign-born patients about how they perceive health, TB or LTBI, to conduct better communication.

PURPOSE:
The purpose of this study was to evaluate the reproducibility and validity of a short food frequency questionnaire (FFQ) for food group intake in Japan, the reproducibility and partial validity of which were previously confirmed for nutrients.
METHODS:
A total of 288 middle-aged healthy volunteers from 11 different areas of Japan provided nonconsecutive 3-day weighed dietary records (DRs) at 3-month intervals over four seasons. We evaluated reproducibility based on the first (FFQ1) and second (FFQ2) questionnaires and their validity against the DRs by comparing the intake of 20 food groups. Spearman's rank correlation coefficients (SRs) were calculated between energy-adjusted intake from the FFQs and that from the DRs.
RESULTS:
The intake of 20 food groups estimated from the two FFQs was mostly equivalent. The median energy-adjusted SRs between the FFQ1 and FFQ2 were 0.61 (range 0.38-0.86) for men and 0.66 (0.45-0.84) for women. For validity, the median de-attenuated SRs between DRs and the FFQ1 were 0.51 (0.17-0.76) for men and 0.47 (0.23-0.77) for women. Compared with the DRs, the proportion of cross-classification into exact plus adjacent quintiles with the FFQ1 ranged from 58 to 86% in men and from 57 to 86% in women. According to the robust Z scores and the Bland-Altman plot graphs, the underestimation errors in the FFQ1 tended to be greater in individuals with high mean levels of consumption for meat for men and for other vegetables for both men and women.
CONCLUSION
The FFQ demonstrated high reproducibility and reasonable validity for food group intake. This questionnaire is short and remains appropriate for identifying associations between diet and health/disease among adults in Japan.
