Abstract
PURPOSE In the event of failed tracheostomy decannulation, patients might have a tragic course of events. We retrospectively evaluated our stepwise tracheostomy decannulation program and examined its safety. METHODS A 12-year retrospective study of pediatric patients was conducted. The decannulation program was performed on patients who had airway patency by laryngobronchoscopy and whose cannula could be capped during the day. A stepwise decannulation program was performed: continuous 48-h capping trial during hospitalization (Phase 1), removal of the tracheostomy tube for 48 h during hospitalization (Phase 2), and outpatient observation (Phase 3). If a persistent tracheocutaneous fistula existed, the fistula was closed by surgery (Phase 4). RESULTS The 77 patients in the study underwent 86 trials. The age at the first time of the decannulation program was 6.5 ± 3.6 years. Sixteen trials failed (18.6%): 8 trials in Phase 1, 2 trials in Phase 2, 4 trials in Phase 3, and 2 trials in Phase 4. Most decannulation failures were due to desaturation in Phase 1/2 and dyspnea in Phase 3/4. The time to reintubation after decannulation was 15-383 days in Phase 3/4. CONCLUSIONS Patients could fail at every phase of the program, suggesting that a stepwise decannulation program contributes to safety.

Abstract
Models of artificial intelligence (AI) that have billions of parameters can achieve high accuracy across a range of tasks1,2, but they exacerbate the poor energy efficiency of conventional general-purpose processors, such as graphics processing units or central processing units. Analog in-memory computing (analog-AI)3-7 can provide better energy efficiency by performing matrix-vector multiplications in parallel on 'memory tiles'. However, analog-AI has yet to demonstrate software-equivalent (SWeq) accuracy on models that require many such tiles and efficient communication of neural-network activations between the tiles. Here we present an analog-AI chip that combines 35 million phase-change memory devices across 34 tiles, massively parallel inter-tile communication and analog, low-power peripheral circuitry that can achieve up to 12.4 tera-operations per second per watt (TOPS/W) chip-sustained performance. We demonstrate fully end-to-end SWeq accuracy for a small keyword-spotting network and near-SWeq accuracy on the much larger MLPerf8 recurrent neural-network transducer (RNNT), with more than 45 million weights mapped onto more than 140 million phase-change memory devices across five chips.

Abstract
Congenital diaphragmatic hernia (CDH) is a life-threatening condition characterized by the herniation of abdominal organs into the thorax, resulting in hypoplastic lungs and pulmonary hypertension. The impact of the first cry, a crucial event for lung transition during birth, on CDH patients remains unclear. This study investigated the impact of the first cry during birth on CDH patient survival, along with other prognosis factors. A multi-institutional retrospective study assessed CDH patient characteristics and survival rates by analyzing factors including the first cry, disease severity, birth weight, Apgar scores, oxygenation index (OI) and surgical closure. Among the CDH patients in the study, a positive first cry was linked to 100% survival, regardless of disease severity (p < 0.001). Notably, the presence of a positive first cry did not significantly affect survival rates in patients with worse prognostic factors, such as low birth weight (<2500 g), high CDH severity, low Apgar scores (1 min ≤ 4), high best OI within 24 h after birth (≥8), or those who underwent patch closure. Furthermore, no significant association was found between the first cry and the use of inhaled nitric oxide (iNO) or extracorporeal membrane oxygenation (ECMO). In conclusion, this study suggests that the first cry may not have a negative impact on the prognosis of CDH patients and could potentially have a positive effect.

Abstract
Abstract
Background
Therapeutic angiogenesis mediated by stem/progenitor cells is an attractive therapeutic option against cardiovascular disease (CVD). Adipose tissue (AT) can be safely obtained even in CVD patients with anti-platelet medications, and it is a readily available source of culture-expanded adipose-derived stem cells (ADSCs) for transplantation. Single-cell transcriptome enables us to screen all the surface markers at once, while conventional strategies have been limited for the number of target markers. Furthermore, gene profiling at single-cell resolution can be used for the quantification of each marker by how many favorable cells can be purified without mixing of detrimental cells.
Purpose
We aimed to identify and characterize a cell population with in vivo angiogenic potential by single-cell RNA sequencing (scRNA-seq) analysis and xenograft experiments.
Methods
We revisited scRNA-seq datasets of single cell fraction from AT, bone-marrow (BM), and umbilical-cord blood (UCB, n=6/organ) to find cell populations with pro-angiogenic potential. Next, we collected AT from CVD patients (n=23) and used multicolor flow cytometry to quantify and sort the specific populations. PBS, the specific marker-negative and unsorted ADSCs were used as controls. Xenograft models of PKH26 pre-labeled human ADSC transplantation in limb ischemia were used to evaluate the lectin capillary density, PKH+ engrafted ADSCs, and blood flow recovery.
Results
Clustering divided CD45–CD31–CD34+ progenitor fraction into 3 clusters. We identified pro-/anti-angiogenic clusters based on the expressions of well-known pro-/anti-angiogenic factors. All genes encoding cell-surface proteins were compared in this functional clustering, resulted in 17 markers screened (Fig. 1A, B). Taken together with enrichment analysis, CD271+ cells showed predominant and pro-angiogenic gene profile from the other top candidates including CD36 and CD54 (Fig. 1C, D). Next, we evaluated the number and gene profile of CD271+ cells in well-known stem cell sources including BM and UCB. Surprisingly, the number of CD271 expressing cells were significantly lower and did not show angiogenic gene profile in BM and UCB (Fig. 2A). In analysis of AT from 23 CVD patients, CD271+ cells were significantly decreased by donor insulin resistance (Fig. 2B). Cell therapy using CD271+ ADSCs demonstrated in vivo angiogenic capacity compared to those of CD271– ADSCs and PBS in limb ischemia model. Furthermore, CD271+ ADSC transplantation showed enhanced efficacy compared to unsorted ADSCs from the same donors (Fig. 2C–E).
Conclusion
In this study, we identified CD271+ cell population in AT as an angiogenic cell population through scRNA-seq analysis and cell therapy experiments. AT obtained from donors without insulin resistance would be the most suitable for CD271+ ADSC isolation. CD271+ ADSC transplantation with a promising angiogenic capacity could contribute better cell-based therapy tackling CVD.

Abstract
BackgroundHypertrophic pachymeningitis (HP), characterized by an inflammatory disorder indicating intracranial or spinal thickening of dura mater, is found to develop as a neurological involvement in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). Meanwhile, the previous studies focusing on HP in AAV have been reported as a single-institution study, and the analyses were performed in a small number of patients because HP is a rare neurological disorder. Therefore, neither etiological nor clinical characteristics of HP in AAV have been adequately elucidated.ObjectivesThis study clarified the characteristics of HP in AAV by analyzing the information of multicenter study in Japan (Japan collaborative registry of ANCA-associated vasculitis: J-CANVAS).MethodsWe analyzed the clinical information from 541 Asian patients with AAV enrolled in J-CANVAS. Of them, newly diagnosed and relapsed AAV were included in 448 and 93, respectively. The epidemiological and clinical findings were compared between patients with and without HP. Clinical manifestations related to AAV were evaluated based on the Birmingham Vasculitis Activity Score version 3. To elucidate independent factors in HP development, logistic regression analyses were additionally performed.ResultsOf the total 541 patients (mean age: 71±14 years, M:F = 1:1.2), HP was demonstrated in 28 (5.17%), including 17 (3.79%) in newly diagnosed AAV and 11 (11.8%) in relapsed AAV. The classification of granulomatosis with polyangiitis (GPA) was significantly higher in patients with HP than those without HP (50% vs. 21%, p = 0.0007). In newly diagnosed AAV, patients with HP significantly had higher GPA classification and higher positivity for PR3-ANCA than those without HP (53% vs. 17%, p = 0.001; 29% vs. 9%, p = 0.015, respectively). Conversely, positivity for MPO-ANCA was significantly higher in patients with HP than those without HP in relapsed AAV (91% vs. 55%, p = 0.025), despite not significantly different in the classification of AAV. Headache and cranial neuropathies were significant neurological symptoms in patients with HP compared to those without HP (82% vs. 6.6%, p < 0.0001; 32% vs. 2.9%, p < 0.0001, respectively). Besides, ear, nose and throat (ENT) and mucous membranes/eyes were significantly higher involvements in patients with HP than in those without HP (54% vs. 26%, p = 0.003; 29% vs. 9%, p = 0.003, respectively). Moreover, higher complications of “conjunctive hearing loss” and “sudden visual loss”, which are included in the categories of ENT and mucous membranes/eyes involvement, respectively, were significantly indicated in patients with HP than those without HP (39% vs. 7.2%, p < 0.0001; 21% vs. 1.2%, p < 0.0001, respectively). Multivariable logistic regression analysis identified that ENT (odds ratio [OR] 1.28, 95% confident interval [CI] 1.09 to 1.49, p = 0.002) and mucous membranes/eyes involvement (OR 1.37, CI 1.14 to 1.65, p = 0.0006), as well as conjunctive hearing loss (OR 4.52, CI 1.56 to 13.05, p = 0.005) and sudden visual loss (OR 1.84, CI 1.12 to 3.00, p = 0.015), were independent related factors in patients with HP.ConclusionGPA could be significantly classified in patients with HP. Notably, patients with HP significantly showed higher positivity for PR3-ANCA than those without HP in newly diagnosed AAV. Furthermore, sudden visual loss and conjunctive hearing loss might be implicated in HP development.Disclosure of InterestsNone declared

Abstract
BackgroundCytomegalovirus (CMV) has been associated with atherosclerosis in patients with chronic renal failure, and may cause secondary nephrotic syndrome. Therefore, we hypothesized that the reactivation of CMV by immunosuppressive therapy in patients with vasculitis may affect renal function.ObjectivesThe purpose of this study was to investigate relationships between CMV infection and renal function during ANCA-associated vasculitis remission induction therapy.MethodsThis retrospective cohort study enrolled microscopic polyangiitis (MPA), granulomatosis with polyangiitis (GPA), and eosinophilic granulomatosis with polyangiitis patients at 25 sites in Japan who had a first or severe relapse between January 2017 and June 2020. Of these, patients with MPA or GPA who had a positive renal lesion score on BVAS (version 3) at baseline, or vasculitis findings on renal biopsy, CMV assayed by 48 weeks of treatment, were included. Patients were divided into two groups based on the presence or absence of a positive CMV antigen test during the remission induction phase (0–48 weeks of treatment). Outcomes were the rate of change in estimated glomerular filtration rate (eGFR) at 48 weeks after initiation of treatment in both groups, as determined by (eGFR at 48 weeks - eGFR at the initiation of treatment)/eGFR at the initiation of treatment; where lower values were associated with worse renal function. General linear models adjusted for age, gender, presence of diabetes or chronic kidney disease, and the use of rituximab or cyclophosphamide were generated.ResultsA total of 387 patients had CMV antigen measured during ANCA-associated vasculitis treatment, of which 164 had renal involvement and eGFR measured at 48 weeks. Seventy-seven (47.0%) were male and the median age was 75 years (range 69–80 years). CMV reactivation was observed in 44 patients (26.8%). The beta coefficient of multiple regression analysis with CMV positive as 1 and negative as 0 was 0.08 (95% confidence interval -0.13 to 0.29) (p = 0.47). The rate of change in eGFR was higher in the CMV positive group, but not statistically significantly.ConclusionContrary to our hypothesis, renal prognoses tended to be better when CMV reactivation was observed. The patients in the CMV reactivation group may have been treated more aggressively, and some patients with a poor prognosis who were not followed up for 48 weeks dropped out. Further research investigating the adjustment of treatment methods is required.Disclosure of InterestsNone declared

Abstract
BackgroundAntineutrophil cytoplasmic antibody -associated vasculitis (AAV) is usually treated with combination of high-dose glucocorticoid (GC) and immunosuppressive agents, followed by tapering GC dose. Although the European League Against Rheumatism (EULAR) has specific recommendations for tapering the GC dose, clinicians often taper it slower than recommended due to concerns of potential disease relapse. However, such slower taper may prolong GC exposure for the patients, increasing the risk of adverse events, particularly infection.ObjectivesThe aims of our study were (1) to clarify GC dose tapering in the treatment of AAV in a real-world setting, in contrast to the EULAR recommendation of 2015 and (2) to compare the incidence of AAV relapse and severe infection between patients underdoing EULAR-recommended tapering and those undergoing slower tapering than the recommendation.MethodsIn this multicenter (25 sites in Japan), observational, retrospective study of AAV, 541 patients who had initial or severe relapse were enrolled between January 2017 and June 2020. Of these, 349 patients with microscopic polyangiitis (MPA) or granulomatosis with polyangiitis (GPA) who entered in GC tapering phase after successful induction treatment were included. These patients were then grouped on the pace of GC tapering, defined as the GC dose at 12 weeks after treatment initiation: (1) EULAR group: 7.5-10 mg/day of GC, according to the EULAR recommendation of 2015, and (2) SLOWER group: >10 mg/day of GC. Their baseline characteristics and clinical outcomes were compared. Primary outcome was defined as relapse-free days from treatment initiation, whereas secondary outcome included the incidence of infectious events requiring hospitalization within 48 weeks from treatment initiation. Multivariable analysis was performed to assess the relationship between tapering pace and clinical outcomes.ResultsThere were 44 patients (12.6%) in the EULAR group and 290 (83.2%) in the SLOWER group. Regarding baseline characteristics, compared with the EULAR group, the SLOWER group had significantly higher serum C-reactive protein level (EULAR, 5.89 ± 6.89 mg/dL vs SLOWER, 7.56 ± 6.01 mg/dL; p = 0.03), as well as a trend toward higher Birmingham Vasculitis Activity Score (version 3) (EULAR, 11.80 ± 7.01 SLOWER, 13.93 ± 7.06; p = 0.08) We did not observe any significant differences in the frequency of relapses between the two groups (EULAR, 8/44, 18.2% vs SLOWER, 55/290, 19.0%; p = 0.63). Multivariable Cox proportional hazard analysis revealed no relationship GC dose at 12 weeks from treatment initiation and incidence of relapse. However, upon logistic regression analysis, the SLOWER group was found to have significant higher risk of a severe infectious event within 48 weeks from treatment initiation (p = 0.046; hazard ratio, 1.27; 95% confidence interval, 1.004 – 1.601).ConclusionOur finding indicates that clinicians tended to taper GC slower for patients with higher disease activity. However, slower GC taper was not found to reduce the frequency of relapse. In addition, slower GC taper was found to increase the risk of a severe infection. Hence, clinicians should pay attention not only relapsing but also late GC taper resulting in the risk of serious infection, especially in patients with higher disease activity of AAV.References[1]Eur J Clin Invest 2015;45 (3): 346–368.[2]Rheumatology (Oxford). 2021 Dec 24;61(1):205-212.[3]Arthritis Res Ther. 2021 Mar 20;23(1):90.[4]Scand J Rheumatol. 2022 Jan 20;1-13.[5]J Rheumatol. 2018 Apr;45(4):521-528.[6]Rheumatol Adv Pract. 2021 Mar 9;5(3):rkab018.[7]Ann Rheum Dis. 2016 Sep;75(9):1583-94.Figure 1.AcknowledgementsWe would like to thank Editage (www.editage.com) for English language editing.Disclosure of InterestsNone declared

Abstract
Abstract
Some patients with coronavirus disease 2019 (COVID-19) experienced sudden death because of sudden symptom deterioration. Thus, an alarm system that could detect early signs of COVID-19 exacerbation beforehand, to prevent serious illness or death of patients while receiving outpatient treatment at home or in hotels is necessary. Here, we tested whether estimated oxygen variations (EOV), a relative physiological scale that represents users' blood oxygen saturation level during sleep measured by Fitbit, predicted COVID-19 symptom exacerbation. Study period was from August to November 2020. We enrolled 23 COVID-19 patients diagnosed by SARS-CoV-2 polymerase chain reaction-positive (mean age ± standard deviation, 50.9±20 years; 70% female), let each patient wore the Fitbit for 30 days; COVID-19 symptoms were exacerbated in 6 (26%). High EOV signal (a patient's oxygen level exhibits significant dip and recovery within the index period) had 80% sensitivity before symptom exacerbations, whereas resting heart rate signal only had 50% sensitivity. Coincidental obstructive sleep apnea syndrome confirmed by polysomnography was detected in a patient by consistently high EOV signals. This pilot study successfully detected early COVID-19 symptoms exacerbation by measuring EOV and may help to identify early signs of COVID-19 exacerbation.

Abstract
PURPOSE Pancreaticobiliary maljunction (PBM) without biliary dilatation is a condition in which dilatation of the bile duct is not seen in patients with PBM. Recently, the Japanese Study Group on Pancreaticobiliary Maljunction (JSGPM) published new diagnostic criteria for PBM. In these criteria, biliary dilatation is defined according to the standard diameter at each age. We reviewed cases of pediatric patients with PBM without biliary dilatation. METHODS From 1992 to 2019, 134 patients with PBM were treated in our institution. Among these, 7 patients were retrospectively diagnosed with PBM without biliary dilatation. The clinical information was retrospectively assessed in these patients. RESULTS Of the seven patients, six were female. All patients had symptoms similar to those of patients with congenital biliary dilatation. In all seven patients, the diagnosis of PBM was made before definitive surgery. Six patients had type B PBM, and one had type D PBM. All patients underwent extrahepatic bile duct resection and hepaticojejunostomy, and their symptoms resolved. One patient experienced postoperative complications of anastomotic leakage followed by anastomotic stricture. CONCLUSION The present report revealed important clinical features of this entity. However, there are still some issues that need to be discussed, and further research is needed.

Abstract
Background:Coronary periarteritis is one of the clinical manifestations of IgG4-related disease. It can cause serious conditions such as angina and ruptured aneurysms. Therefore, it is important to recognize the clinical and radiological characteristics, which was little known.Objectives:We report four patients with IgG4-related coronary periarteritis with a systematic literature review.Methods:We identified four patients with IgG4-related coronary periarteritis at the St. Luke’s International Hospital in Tokyo, Japan from 2014 to 2020. A systematic literature review was conducted for English articles on IgG4-related coronary periarteritis cases with a full text or abstract available. We summarized patient demographics, IgG and IgG4 titers, the site and morphological type of coronary lesion, and other organ involvements.Results:Our 4 cases and 38 cases identified by the literature review were assessed. Coronary artery lesions were detected by a coronary CT in all but two cases. Wall thickening was the most common type of the lesion. Moreover, there were 32 (76.1%) patients with other organ involvements. The commonest other lesion was peri-aortitis in 21 (50.0%) patients. In cases with peri-aortitis, IgG and IgG4 titers were significantly higher than those without peri-aortitis (IgG4; 1540 [705.0, 2570.0] vs 246.0 [160.0, 536.3]; p = 0.001, IgG; 3596.5 [2838.3, 4260.0] vs 1779.0 [1288.3, 1992.8]; p =0.040). In addition, 15 (71.4%) patients of them had three or more IgG4 related organ involvements.Conclusion:Coronary CT was a useful imaging modality for the diagnosis of IgG4-related coronary periarteritis, and wall thickening was the most common lesion. Moreover, about half cases coexisted with peri-aortitis. Peri-aortitis and other organ involvements should be screened in those with higher IgG and IgG4.Table 1.Characteristics of our cases and the literature review cases.RCA: right coronary artery, LAD: left anterior descending artery, LCx: left circumflex arteryDisclosure of Interests:None declared

Abstract
Foreign body aspiration (FBA), with potentially life-threatening outcomes, is not unusual in the pediatric population. We report two cases of lobar bronchial radiolucent foreign bodies. Chest X-ray (CXR) showed a slight but significant finding of lobar emphysema without a significant mediastinal shift. This is possibly a key to suspecting foreign bodies. In the clinical field, a stepwise approach to detecting foreign bodies is commonly performed, from less invasive options such as CXR to computed tomography (CT). In this context, clinicians should scrupulously check CXRs when pediatric patients complain of respiratory symptoms, especially with potential FBA history.

Abstract
PURPOSE In postoperative cases of fundoplication, the gastric emptying ability is promoted and sometimes exhibits dumping syndrome. Dumping syndrome often goes unrecognized in children. Furthermore, the risk factors for postoperative dumping syndrome are unknown. This study aimed to investigate the risk factors of developing dumping syndrome after fundoplication. METHODS A retrospective chart review of all consecutive patients between January 2003 and March 2018 (190 patients) who had fundoplication at our clinic was conducted. Regarding the risk factors of dumping syndrome, gender, age and body weight at the time of surgery, neurological impairment, severe scoliosis, microgastria, chromosomal abnormalities, complex cardiac anomalies, gastrostomy, and laparoscopic surgery were retrospectively studied. RESULTS 17 patients (9%) developed dumping syndrome post-operatively. Multivariate analysis showed that significant risk factors for dumping syndrome included: undergoing surgery within 12 months of age (adjusted OR 10.3, 95% CI 2.6-45.2), severe scoliosis (adjusted OR 19.3, 95% CI 4.4-91.1), and microgastria (adjusted OR 26.5, 95% CI 1.4-896.4). CONCLUSIONS We identified that: age at fundoplication being within 12 months of age, severe scoliosis, and microgastria were risk factors for dumping syndrome after fundoplication, and that this information should be explaining to the family before conducting the fundoplication.

Abstract
Constant neck flexion has been considered crucial to reducing anastomotic tension after tracheal resection. However, in rare cases, anteflexion can cause cervical cord damage, leading to acute neurological disorders such as tetraplegia. Here, we report a case of 5-year-old boy presenting with acute neurological disorder triggered by a chin-to-chest position over 4 days of deep sedation after cricotracheal resection. The radiological findings would suggest a mechanism similar to Hirayama disease, in which a shift of the dura leads to chronic muscular weakness and atrophy in young populations.

Background
Early diagnosis and timely treatment for the patients with familial hypercholesterolemia (FH) can substantially lower the risk of atherosclerotic cardiovascular disease (ASCVD). In this sense, cascade screening could be one of the most useful options. However, few data exist regarding the impact of cascade screening for FH on the reduction of risk of ASCVD events.
Objectives
We aimed to evaluate the prognostic impact of cascade screening for FH.
Methods
We retrospectively investigated the health records of 1,050 patients with clinically diagnosed FH, including probands and their relatives who were cascade-screened. We used Cox models that were adjusted for established ASCVD risk factors to assess the association between cascade screening and major adverse cardiovascular events (MACE). The median period of follow-up was 12.3 years (interquartile range [IQR] = 9.1–17.5 years), and MACE included death from any causes or hospitalization due to ASCVD events.
Results
During the observation period, 246 participants experienced MACE. The mean age of patients identified through cascade screening was 18-years younger than that of the probands (38.7 yr vs. 57.0 yr, P<0.001), with a lower proportion of ASCVD risk factors. Interestingly, patients identified through cascade screening under milder lipid-lowering therapies were at reduced risk for MACE (hazard ratio [HR] = 0.36; 95% CI = 0.22 to 0.60; P<0.001) when compared with the probands, even after adjusting for those known risk factors.
Conclusions
The identification of patients with FH via cascade screening appeared to result in better prognoses.

Abstract
BACKGROUND Although pediatric tracheostomy has been a widely performed, life-saving procedure, its long-term outcomes have remained unclear. This study aimed to review outcomes after tracheostomy at a Japanese tertiary hospital and clarify candidates for and timing of decannulation. MATERIALS AND METHODS Hospital records of critically ill children who underwent tracheostomy from 2001 to 2014 were retrospectively reviewed, subsequently analyzing outcomes according to demographics, complications, and decannulation. After excluding those who were lost to follow-up or had irreversible neuromuscular impairment, the remaining patients were divided into the decannulation (D group) and nondecannulation (ND group) groups and compared. RESULTS In total, 184 patients who underwent tracheostomy were analyzed (median age at operation: 0.5 y). The major indication for tracheostomy was irreversible neuromuscular impairment (46%). Surgery-related and overall mortality rates were 1% and 25%, respectively, while the successful decannulation rate was 21%. No significant difference in surgical indications or comorbidities was observed between the D (n = 39) and ND (n = 50) groups, except for infection (7 in D group versus 0 in ND group; P = 0.002) and chromosome-gene disorder (15% versus 34%; P = 0.04). The ND group had a significantly higher mortality rate than the D group (46% versus 3%; P < 0.0001). The median time to decannulation was 3.6 years, while that for infection was 0.7 y. CONCLUSIONS Patients who underwent tracheostomy at our institution due to temporary infections achieved more successful and earlier decannulation compared to other indications. Chromosome-gene disorder as a comorbidity can negatively affect decannulation.

Abstract
Neonatal free air on X-ray images is generally due to intestinal perforation, and requires surgical intervention. However, some cases without intestinal perforation show free air on X-ray images. Pneumoperitoneum without perforation is caused by an air leak syndrome. We present here the case of a low-birth-weight infant with free air on X-ray images, who had no evidence of intestinal perforation intraoperatively.

Abstract
PURPOSE The aim of this study was to evaluate the clinical outcomes and postoperative anorectal function in the patients with high/intermediate imperforate anus (HIA/IIA) treated in our institution. In addition, we report our novel procedure, laparoscopically assisted anorectoplasty with anterior perineal incision (LAARP-API), which allows direct approach to the anterior edge of the puborectal sling and muscle complex, and is useful for the creation of a pulling-through route for the rectal pouch. METHODS From 1976 to 2016, 22 patients with HIA and 43 patients with IIA underwent sacroperineal/sacroabdominoperineal pull-through anorectoplasty (SP/SAP), Potts procedure (Potts), SP with API (SP-API) or LAARP-API. Clinical data and anorectal function of those patients were retrospectively evaluated using the Japanese clinical score. RESULTS Of the 22 cases of HIA, 15 were treated by SAP, 2 were SP and 5 were LAARP-API. Of the 43 cases of IIA, one was treated by SAP, 31 were SP, two were Potts and nine were SP-API. The mean score of anorectal function of HIA/IIA both increased with age. In IIA, the score after SP-API was significantly higher than the score after SP. CONCLUSION Long-term outcomes of our anorectoplasty for HIA/IIA are good with excellent anorectal function score.

Abstract
BACKGROUND This study assessed the necessity of postoperative nasogastric tube (NGT) use in acute pediatric cases of perforated appendicitis. METHODS All cases of acute pediatric perforated appendicitis managed with transumbilical laparoscopic-assisted appendectomy at our hospital from 2011 to 2017 were retrospectively reviewed. Sixty-two cases were selected and divided into two groups based on NGT placement. RESULTS There were no significant differences between the two groups in most parameters of patient demographics, or surgical data. Notably, the mean time to first oral intake and to regular diet was significantly shorter in no-NGT group (1 day vs 3 days, P < 0.0001; and 4 days vs 7 days, P = 0.003, respectively). Postoperative length of stay was significantly shorter in no-NGT group (7 days vs 9 days, P < 0.0001). CONCLUSION Considering the results of our analysis, we believe that routine NGT placement is not always necessary in these situations.

Abstract
OBJECTIVES Whether to perform surgical or conservative treatment for congenital tracheal stenosis (CTS) is controversial. Thus, the computed tomography (CT) criteria for conservative treatment of CTS were investigated. METHODS From 2005 to 2017, 28 CTS cases were included. The operative cases and preoperative death cases constituted the required intervention group (group I), and the non-operative surviving cases constituted the observation group (group O). The diameter of the tracheal narrowest part (DTNP) on CT was evaluated as a criterion for non-operative follow-up. RESULTS Chest CT was performed 19 times in 19 group I cases and 18 times in 9 group O cases. The median age of the patients that underwent CT scan examinations was 3.4 months (range 0-25 months) in group I and 22 months (range 0-60 months) in group O. The cut-off values of the non-operative criteria were 40.8% (AUC: 0.82, p < .01) normal for age of the trachea's narrowest part, and 41.6% normal for body weight (AUC: 0.92, p < .01), respectively. CONCLUSIONS DTNP is 40% and more of the normal diameter appears necessary for non-surgical management. The present study suggests that the criteria for conservative management of CTS are that the DTNP is not less than 40% of the normal tracheal diameter, with a few symptoms.

Abstract
Abstract
Background/Introduction
Cardiac sarcoidosis (CS) is one of the main causes of poor outcomes in patients with sarcoidosis, a systemic granulomatous disorder of complex etiology including a genetically susceptible host and specific exposure to disease-triggering antigens. Recently, transcriptome analysis using sarcoidosis peripheral monocytes was reported to be useful for exploring genetic susceptibility and novel disease-causing pathways. However, transcriptome sequencing has not been used to explore disease-related genes and pathways directly using human CS myocardial biopsies.
Purpose
This study aimed to identify transcriptome profiles and novel disease-related pathways of CS by comparing human CS myocardial biopsies with control samples using ribonucleic acid (RNA) sequencing (RNA-Seq).
Methods
We assessed 30 patients with suspected myocardial disorders who underwent transcatheter endomyocardial biopsies at our University Hospital, Japan. Of those, 7 were clinically diagnosed with CS, 9 with hypertrophic cardiomyopathy (HCM), and 14 with dilated cardiomyopathy (DCM). Messenger RNAs were extracted from cardiac muscle biopsies using the Ovation SoLo RNA-Seq System (NuGEN Technologies), according to the manufacturer's instructions. Sequencing was performed with coverage of approximately 20 million reads per sample using Illumina HiSeq 2000. Sequencing reads were mapped using the STAR 2-pass method with GRCh37 as the reference. The DESeq2 R package (version 3.8) was used for further analyses. Principal component analysis (PCA) on gene expression was conducted for detecting outliers such as non-muscular samples. Differential gene expression analysis was performed between the 7 patients with CS and 23 patients with cardiomyopathy (HCM and DCM, non-CS). Gene Ontology (GO) enrichment analysis was conducted to estimate possible disease-related pathways.
Results
We successfully sequenced 60 myocardial biopsy samples (original and biological duplicates) from 30 CS patients. Of these, 2 outlier samples shown by the PCA plot were removed, and 58 were used for further analyses. We found 243 genes that were differentially expressed between CS patients and non-CS patients. Top-rated genes were RP11–366M4.8, RELN, S100A6, WASF3and UCHL1. Pathway analysis using GO demonstrated enrichment oflymphocyte activation (P=4.8x10–16), organelle fission (P=6.1x10–14), the M phase of the mitotic cell cycle (P=2.2x10–13), nuclear division (P=2.4x10–13), mitosis (P=2.4x10–13) and T-cell activation pathways (P=1.2x10–12).
Conclusions
Our differential gene expression and pathway analysis results using human CS myocardial biopsies suggested that lymphocyte activation, specifically the T-cell activation pathway, is linked to CS pathogenesis. Further studies are needed to decipher the role of specific genes related to genetic susceptibility and/or pathways associated with CS occurrence.

Abstract
Abstract
Background
Therapeutic angiogenesis using adipose-derived stem cells (ADSCs) is an attractive strategy for ischemic cardiovascular diseases. We previously reported that human CD271+ population of adipose-derived stem cells (ADSCs) promoted neovascularization with enhanced engraftment in a mouse model of hindlimb ischemia. However, whether and how CD271+ ADSCs promote the long-term engraftment is still uncertain.
Purpose
We aimed to examine whether the angiogenic effect and cell engraftment capacity of CD271+ ADSCs would be sustained in long-term period. Then, comparative gene profiling between CD271+ and CD271- ADSCs were analyzed. Finally, cell proliferation and endothelial differentiation assays were conducted.
Methods
ADSCs were isolated from subcutaneous adipose tissue of 5 patients received cardiovascular surgery. CD271+ and CD271- ADSCs were sorted from CD45-CD31-CD34+ ADSCs fraction by FACS sorting (Fig. A). Cultured CD271+ and CD271- ADSCs at passage 6 were labeled by PKH26 cell linker dye and used for xenograft experiments. Briefly, athymic nude mice were subjected to hindlimb ischemia and one million of human ADSCs were injected into the ischemic muscles. In control group, PBS was solely injected. At 2 and 5 weeks, neovascularization was evaluated by immunohistochemistry (capillary density using lectin perfusion). Cell engraftment was assessed by counting PKH26-positive cells. Furthermore, we compared gene profiling between CD271+ and CD271- ADSCs by microarray. Proliferative capacity was evaluated by colony-forming unit (CFU) assay with Giemsa staining. In endothelial differentiation assay, CD271+ and CD271- ADSCs were cultured in differentiation induction medium containing vascular endothelial growth factor for 2 weeks and stained with anti-human CD31 antibody.
Results
Cell therapy using CD271+ ADSCs demonstrated approximately 3-fold more enhanced neovascularization than those using CD271- ADSCs or PBS in histological analysis of capillary density at 2 weeks from cell therapy (Fig. B and C). At 5 weeks, mice treated with CD271+ ADSCs were significantly rescued from limb ischemia and this was accompanied by sustained engraftment of ADSCs (Fig. D). In microarray analysis, the differentially expressed 2167 genes were extracted to classify CD271+ and CD271- ADSCs. Pathway analysis demonstrated CD271 expression on ADSCs was associated with the pathways related to stemness and cell differentiation. Indeed, we found that genes related to cell proliferation (PI3K, Cyclin D, and Cyclin D2) were up-regulated in CD271+ ADSCs. Additionally, we found the pericytic marker nestin which was significantly up-regulated in CD271+ ADSCs. Consistent with these findings, CD271+ ADSCs were more proliferative and capable for endothelial differentiation while CD271- ADSCs were not.
FACS and cell therapy experiments
Conclusion
These results suggest that CD271+ ADSCs possess long-term engraftment and angiogenic capacity due to their less-aged and more pericytic gene profile.

Abstract
Background
Although awareness of familial hypercholesterolemia (FH) is increasing, this common, potentially fatal, treatable condition remains underdiagnosed. Japanese clinical diagnostic criteria of FH include LDL cholesterol level ≥180 mg/dl, Achilles tendon thickness (ATT) ≥9.0 mm, and family history of FH or premature coronary disease. Despite FH being a genetic disorder, genetic testing is rarely used, few data exist regarding the validation of those criteria, especially, by studies using comprehensive genetic analyses.
Methods
This study included 680 subjects (344 men, mean LDL cholesterol = 175 mg/dl) who underwent the full assessments for FH, including LDL cholesterol measurement, Achilles tendon X-ray, investigations for family history, and comprehensive genetic analyses on FH-associated genes (LDL receptor, PCSK9, APOB, and LDLRAP1) in our University Hospital since 2006 to 2018. The area under curve (AUCs) of receiver-operating characteristic (ROC) curve analyses predicting FH-mutation positive were compared among those determined by each component.
Results
ROC analyses revealed the optimal cutoff LDL cholesterol value for predicting the presence of FH-mutation was 181 mg/dl, and that of ATT was ≥7.0 mm. AUCs of each component (ATT, LDL cholesterol, and family history) were 0.827, 0.889, and 0.906, respectively, and the combination of all components increased it to 0.975. When adopting ATT ≥7.0 mm as one of the clinical diagnostic criteria, 13 individuals (2%) were newly classified as true-FH, whereas, 27 (4%) individuals were newly misclassified as FH.
Conclusion
The current Japanese clinical diagnostic criteria of FH were pretty well validated in our independent cohort. However, the threshold of ATT could be lowered to 7.0 mm to raise the sensitivity of its criteria.

Abstract
PURPOSE Intestinal aganglionosis (IA) is so rare that the entity remains unclear. The aim of the present study was to compare the outcomes of patients with IA and those with total colonic aganglionosis (TCA). METHODS The hospital records were retrospectively reviewed from 1977 to 2018. Outcomes were analyzed for the IA group and the TCA group, including clinical presentation, initial management, and operative details. RESULTS There were six patients were managed in IA (all male) and seven patients in TCA (4 male). The median age at the first operation was significantly younger in IA than TCA (2 days vs 24 days, p = 0.01). The gap between the intraoperative caliber change (CC) of the intestine and the initial stoma location was not significantly different (7.5 cm vs 12 cm, p = 0.61), but the rate of stoma dysfunction was significantly higher in IA (83% vs 0%, p = 0.005). The gap between the CC and the ganglionated bowel was significantly longer in IA (85 cm vs 10 cm, p = 0.003). CONCLUSION Patients with IA appear to have a high risk for stoma dysfunction after the first operation because of the unexpected gap between the CC and normoganglia. The initial location of the stoma requires careful consideration.

Abstract
BACKGROUND Mesentero-axial gastric volvulus (MAGV) is a rare but critical condition as delay in treatment can lead to lethal situations. Although the report of the surgical treatment with laparoscopic approach for MAGV has recently come to be seen, no standard procedures have been established. We aim to describe our operative technique of single-incision laparoscopic gastropexy (SILG) for MAGV and review the relevant literature to ascertain the most appropriate treatment option in these patients. CASE PRESENTATION Three patients were referred to our hospital because abdominal pain and vomiting suddenly occurred. Acute MAGV was diagnosed by upper gastrointestinal study. After overnight gastric decompression with a nasal tube, the GV was resolved spontaneously. Elective SILG was planned. Single incision at the umbilicus was made and three 5-mm trocars were inserted. The anterior wall of the body of the stomach was sutured to the peritoneum using 6 × 4-0 non-absorbable sutures for prevention of recurrence of GV and occurrence of internal hernia through the space created between the sutures. Two boys and a girl with mean age 4 ± 2 years underwent SILG. The mean time of the operation was 48 ± 23 min. All of the procedures were completed safely, and there were no postoperative complications. The mean time of postoperative hospitalization was 4 ± 1 days. All patients had good cosmetic and clinical results. CONCLUSION We found SILG is a safe, technically feasible, and minimally invasive approach with low incidence of postoperative complication and the best cosmetic result for the patients with MAGV.

Abstract
BACKGROUND The aim of the present study was to investigate the characteristics, management, and outcomes of congenital biliary dilatation (CBD) in neonates and infants (<1 year old) in a single institution over the past 20 years. METHODS From 1997 to 2016, 21 patients <1 year old underwent definitive surgery for CBD. Open surgery (OS) was performed between 1997 and 2008, and laparoscopic surgery (LS) has been performed since 2009. RESULTS The bile duct showed cystic dilatation in all patients. Sixteen (76.2%) of the 21 patients were diagnosed prenatally, and the incidence increased with time (OS 63.6%, LS 90%). Fourteen patients (66.7%) were symptomatic before surgery, with jaundice in 11 (52.4%), acholic stool in seven (33.3%), and vomiting in three (14.3%). There were no significant differences in operation time and blood loss, but the postoperative fasting period and hospital stay were significantly shorter in the LS group (P < 0.05). There were no intraoperative complications, but there was one postoperative early complication in one LS group patient, who had bile leakage and was treated with redo hepaticojejunostomy. CONCLUSION The incidences of prenatally diagnosed and asymptomatic patients increased with time. Although longer follow-up is needed, LS for CBD could be safely performed even in neonates and early infants.

Abstract
PURPOSE Long-term intubation of premature infants sometimes induces acquired subglottic stenosis (SGS), causing glottic or supraglottic problems. These kinds of SGS often require tracheostomy and subsequently make decannulation difficult. The aim of our study was to clarify the efficacy of repeated intralesional steroid injections to the stenosis. METHODS Six children with acquired SGS, who were treated with triamcinolone acetonide injections to the subglottic space just below the vocal folds between September 2015 and December 2017 were retrospectively reviewed. RESULTS The patients' mean age was 4.3 (range 1.3-4.4) years, the mean gestational age at birth was 25 (23-28) weeks, and the mean birth weight was 591 (456-734) g. The degree of SGS was grade II in one patient and III in five patients, with both tracheostoma and glottic or supraglottic abnormalities. They generally underwent ten procedures, every 3-4 weeks. In most cases, the patency of the injected space improved by 25-220%, and the symptoms were relieved. One patient achieved decannulation, and another one underwent laryngotracheal reconstruction and decannulation. Two patients started using a speech cannula. There were no severe complications. CONCLUSION Serial intralesional steroid injections are likely to be effective in improving the patency of acquired SGS.

Abstract
PURPOSE The aim of this study was to investigate the risk factors for in hospital mortality in infants with esophageal atresia (EA) without critical chromosome abnormality disorders and develop a new prognostic classification to assess the influence of external risk factors on the prognosis of EA, which could provide more effective treatment strategies in clinical practice. METHODS A retrospective chart review of all consecutive patients between January 1994 and December 2017, which included 65 EA infants who were admitted to Shizuoka Children's Hospital, was conducted. Based on multivariate analysis data and ROC analysis, the discrimination of the new prognostic classification was quantified and compared with that of the Spitz classification using the area under the ROC curve (AUC). RESULTS Multiple logistic regression analysis showed that birth weight of < 1606 g (adjusted OR, 13.16; 95% CI, 1.16-352.75), and complex cardiac anomalies (adjusted OR 22.39; 95% CI 2.45-569.14) were significant risk factors for death. We have created a new classification close to Spitz classification using the presence of complex cardiac anomalies and birth weight. The mortality rates were 0% for class I (n = 0/40), 7.1% for class II (n = 1/14), 33.3% for class III (n = 3/9), and 100% for class IV (n = 2/2). The AUC of the new classification was better than that of the Spitz classification (0.939 vs 0.812, respectively; p = 0.04). CONCLUSION New prognostic classification can improve the stratification of EA patients and be a useful predictor of survival.

Abstract
Background A pyriform sinus fistula (PSF) is a rare branchial anomaly that causes recurrent cervical infections. Open neck surgery has widely been accepted as a definitive treatment for PSFs, and endoscopic surgery has been reported in recent years. However, both approaches are not satisfactory because of high recurrence rates and postoperative complications. Microlaryngoscopic surgery (MLS) is a transoral surgical technique involving the use of an operating microscope. In this report, we present a new procedure involving MLS for resection and closure of a PSF without a skin incision. Case presentation Technique: MLS was performed under general anesthesia with endotracheal intubation. The patient was placed in the supine position, and a direct laryngoscope was inserted to expose the pyriform sinus, which was then magnified using an operating microscope. The mucosal layer was carefully resected using scissors and cupped forceps with sharp edges. The fistula was securely sutured using absorbable suture material. Case 1: A 9-year-old boy with recurrent neck abscesses since 8 years of age presented to our hospital after receiving antibiotics and undergoing drainage in other hospitals. After admission to our hospital, barium esophagography and oral contrast coronal computed tomography showed a PSF on the left side, and open neck surgery was performed to resect the fistula. He was eventually discharged from the hospital without any problem. However, a PSF recurred 2 weeks later. As reoperation with the cervical approach was considered difficult owing to severe adhesions, we adopted MLS as a definitive operation. The postoperative course was uneventful. No recurrence was observed during an 18-month follow-up. Case 2: A 10-year-old girl presented to our hospital with recurrent left-sided neck swelling since 6 years of age. After inflammation control, a PSF was identified on the left side on barium esophagography and computed tomography. MLS was performed safely, and the postoperative course was uneventful. No recurrence was observed during a 10-month follow-up. Conclusions MLS allows excellent visualization and effective closure for PSFs, and this approach is suitable for recurrence after open neck surgery. Therefore, MLS might become a first-line treatment for PSFs in children.

Abstract
Background: Single-incision laparoscopic appendectomy (SILA) is a potentially safe and feasible alternative to conventional laparoscopic appendectomy using three ports (CLA). However, the safety and efficacy of SILA for complicated appendicitis (gangrenous and perforated) remain unclear. The aim of this study was to evaluate the outcomes of transumbilical laparoscopic-assisted appendectomy (TULAA) not only for simple appendicitis but also for complicated appendicitis, and to compare them with the outcomes of CLA. Methods: All cases of acute pediatric appendicitis who underwent laparoscopic appendectomies in our hospital from 2007 to 2016 were retrospectively reviewed. CLA was performed between January 2007 and October 2011, and TULAA was performed between November 2011 and December 2016. In this study, patients' demographics and operative outcomes for simple appendicitis (catarrhal and phlegmonous) and complicated appendicitis were analyzed, comparing the results of TULAA and CLA. Results: In total, 262 patients underwent laparoscopic appendectomy: CLA in 103 patients and TULAA in 159 patients. All appendectomies were performed in the acute phase. Complicated appendicitis accounted for 60 CLA cases and 81 TULAA cases. There were no significant differences in patients' demographics. Mean operative time in simple appendicitis was significantly shorter in TULAA than in CLA. In addition, complication rates in complicated appendicitis were significantly lower in TULAA than in CLA. Moreover, in each comparison, the postoperative hospital stay was significantly shorter in TULAA than in CLA. Conclusion: In our institution, TULAA has shown to be a safe and effective alternative for both simple and complicated appendicitis in children compared with CLA.

Abstract
Acquired dermal melanocytosis of the face and extremities (ADMFE) is an unusual form of acquired dermal melanocytosis (ADM). In this paper, we report a case of ADMFE and review the published literature. Our review highlights several clinical differences between ADMFE and ADM: (i) more frequent involvement of the nasal alae in ADMFE than in ADM, (ii) less frequent involvement of the cheeks in ADMFE than in ADM, (iii) limbs affected in all cases of ADMFE but in few cases of ADM, and (iv) frequent involvement of conjunctiva and/or gingiva in ADMFE but very rare involvement in ADM. These findings strongly support the hypothesis that ADMFE is clinically distinct from the classic form of ADM, and gaining an understanding of its phenotype will enable accurate diagnosis and early intervention by Q-switched laser therapy, which should benefit those patients with disease-related cosmetic issues.

Abstract
PURPOSE We investigated the developmental changes in the unaffected contralateral lungs of patients with isolated left-sided congenital diaphragmatic hernia (CDH) using signal intensity ratios on prenatal magnetic resonance imaging (MRI) and determined whether these changes correlated with clinical outcomes. METHODS We performed 47 fetal MRI screens on 30 patients with isolated left-sided CDH. A cohort of 88 fetuses was selected as the control. We calculated the lung-to-liver signal intensity ratio (LLSIR) using region of interest analysis and compared LLSIR between the groups and between those in the CDH group with good and poor prognoses. RESULTS In the control group, LLSIR increased as pregnancy progressed [regression line = 2.232 + 0.135 × (GW-23), r = 0.669]. In the CDH group, especially in the poor prognosis group, LLSIR did not significantly increase as pregnancy progressed [regression line for good prognosis = 1.827 + 0.092 × (gestational week-23), r = 0.733; regression line for poor prognosis = 1.731 + 0.025 × (gestational week-23), r = 0.634]. CONCLUSION Fetal LLSIR on T2-weighted MRI is an accurate marker of fetal lung maturity that correlates with postnatal survival and can potentially be used as a prognostic parameter in CDH management.

Abstract
BACKGROUND The use of laparoscopic percutaneous extraperitoneal closure (LPEC) for pediatric inguinal hernia has recently been increasing. Recurrence and contralateral metachronous inguinal hernia (CMIH) are important problems for LPEC. This study analyzed the risk factors for recurrence and CMIH. METHODS This study included 1530 patients. The mean follow-up period was 48months. Of 1530 patients, 847 were boys and 683 were girls. The mean age at operation was 3.9years. The asymptomatic contralateral internal ring was routinely observed during the operation, and when a patent processus vaginalis (PPV) was confirmed, prophylactic surgery was performed. RESULTS Recurrence was seen in 0.48% of patients (8/1653 sides), all of whom were male (P=0.01: male versus female). On multivariate analysis, age less than 1year was the only risk factor for recurrence in male patients (hazard ratio: 4.54, 95% CI: 1.07-19.25, P=0.04). CMIH was seen in 0.22% of the patients (3/1382), again only in male patients (P=0.12: male versus female). As a result of intraoperative observation, 44.6% of patients were confirmed to have an asymptomatic contralateral PPV and underwent prophylactic LPEC. Female, age 1year or older, right side, and surgeon's experience were identified as factors associated with asymptomatic contralateral PPV. CONCLUSIONS To prevent recurrence, surgeons need to be careful when operating on young male patients. Whereas no specific factor could be identified as a risk factor for CMIH, some factors associated with asymptomatic PPV were identified. Further study and discussion will be needed to identify correlations between CMIH and these factors for PPV. LEVEL OF EVIDENCE Level III.

Abstract
PURPOSE Surgical intestinal disorders (SID), such as necrotizing enterocolitis (NEC), focal intestinal perforation (FIP), and meconium-related ileus (MRI), are serious morbidities in extremely low birth weight (ELBW, birth weight <1000 g) infants. From 2010, we performed enteral antifungal prophylaxis (EAP) in ELBWI to prevent for SID. The aim of this study was to identify disease-specific risk factors and to evaluate the efficacy of prevention for SID in ELBW infants. METHODS A retrospective chart review of all consecutive patients between January 2006 and March 2015, which included 323 ELBW infants who were admitted to Shizuoka Children's Hospital, was conducted. RESULTS The number of infants with NEC, FIP, and MRI was 9, 12, and 13, respectively; 28 in 323 ELBW infants died. The control group defined the cases were not SID. In-hospital mortality was higher in infants with NEC relative to those in the control group. On logistic regression analysis, low gestational age and cardiac malformations were associated with increased risk of NEC. IUGR were associated with increased risk of MRI. EAP decreased risk of NEC and FIP. Low gestational weight and NEC were associated with increased risk of death. CONCLUSION Survival to hospital discharge after operation for NEC in ELBW infants remains poor. EAP decreased risk of NEC and FIP in ELBW infants.
