RESUMO
PURPOSE: To determine the methylation level of the miR-124 promoter in non-neoplastic rectal mucosa of patients with pediatric-onset ulcerative colitis (UC) to predict UC-associated colorectal cancer (UC-CRC). METHODS: Between 2005 and 2017, non-neoplastic rectal tissue specimens were collected from 86 patients with UC, including 13 patients with UC-CRC; cancer tissues were obtained from the latter group. The methylation status of the miR-124 promoter was quantified using bisulfite pyrosequencing and compared between pediatric- and adult-onset UC patients. RESULTS: Patients with pediatric-onset UC experienced a significantly shorter disease duration than those with adult-onset UC. The levels of miR-124 promoter methylation in non-neoplastic rectal mucosa were positively correlated with the age at the diagnosis and duration of UC. The rate of increase in miR-124 methylation was accelerated in patients with pediatric-onset UC compared to those with adult-onset UC. Furthermore, the miR-124 methylation levels in non-neoplastic rectal mucosa were significantly higher in patients with UC-CRC than in those with UC alone (P = 0.02). A receiver operating characteristic analysis revealed that miR-124 methylation in non-neoplastic tissue discriminated between patients with pediatric-onset UC with or without CRC. CONCLUSION: miR-124 methylation in non-neoplastic rectal mucosa may be a useful biomarker for identifying patients with pediatric-onset UC who face the highest risk of developing UC-CRC.

BACKGROUND: Tobacco ingestion is widely known to cause nicotine toxicity, which may result in severe symptoms. Two heated tobacco sticks, called TEREA™ and SENTIA™, were launched in 2021 by Philip Morris International (New York, NY, USA), and their ingestion is associated with a risk of bowel injury because they contain a partially pointed metallic susceptor. However, this risk is not well known to the general public or healthcare providers. To increase awareness of this risk, we herein report a case involving extraction of a metallic susceptor after ingestion of the heated tobacco stick TEREA™. CASE PRESENTATION: A 7-month-old girl presented to the emergency department of a nearby hospital because she was suspected to have accidentally swallowed heated tobacco. Although she presented with no symptoms related to nicotine poisoning, abdominal X-ray examination revealed a metal object in her stomach. According to a statement released by the Japan Poison Information Center, the TEREA™ heated tobacco stick contains a metallic susceptor with a rectangular shape and sharp corners. The patient was transferred to our department because of the risk of bowel injury, and upper gastrointestinal endoscopy was performed. No cigarettes were found by endoscopic observation; however, a metallic susceptor was located in the second part of the duodenum. We grasped it with biopsy forceps and carefully removed it using an endoscope with a cap attached to the tip. The post-endoscopic course was uneventful. CONCLUSIONS: Some patients who ingest heated tobacco sticks might be exposed not only to the effects of nicotine but also to physical damage caused by a metallic susceptor. Infants and toddlers especially could swallow these sticks, therefore tobacco companies need to make the problem more public. Clinicians also should alert the problem, and pay attention to this risk in the clinical setting.

PURPOSE: To assess the severity of preoperative myopenia and myosteatosis in pediatric patients with inflammatory bowel disease (IBD) and examine their impact on postoperative complications. METHODS: The subjects of this retrospective study were 30 pediatric patients with IBD (22 with ulcerative colitis (UC) and 8 with Crohn's disease (CD)) and 67 age-matched controls. Preoperative body mass index (BMI), psoas muscle index (PMI), and intramuscular adipose tissue content were compared between the patient groups, to investigate their association with postoperative complications. RESULTS: BMI and PMI were significantly lower in the IBD patients than in the controls (p < 0.0001, p < 0.0001, respectively). CD was associated with significantly lower BMI and PMI (p = 0.01, p = 0.01, respectively) than UC. Intramuscular adipose tissue content was comparable between the IBD patients and the controls and between the UC and CD patients. There were no significant differences among the three indices in relation to the presence or absence of postoperative complications in patients with IBD. When limited to surgical site infection (SSI), only PMI was significantly lower in the patients with SSI than in those without SSI (p = 0.04). CONCLUSIONS: Although BMI and PMI were lower preoperatively in pediatric IBD patients than in controls, only myopenia seemed to affect the development of SSI.

The study aimed to develop a pulmonary circulatory system capable of high-speed 3D reconstruction of valve leaflets to elucidate the local hemodynamic characteristics in the valved conduits with bulging sinuses. Then a simultaneous measurement system for leaflet structure and pressure and flow characteristics was designed to obtain valve leaflet dynamic behaviour with different conduit structures. An image preprocessing method was established to obtain the three leaflets behaviour simultaneously for one sequence with two leaflets images from each pair of three high-speed cameras. Firstly, the multi-digital image correlation analyses were performed, and then the valve leaflet structure was measured under the static condition with fixed opening angles in the water-filled visualization chamber and the pulsatile flow tests simulating paediatric pulmonary flow conditions in the different types of conduit structures; with or without bulging sinuses. The results showed the maximum 3D reconstruction error to be around 0.06 mm. In the steady flow test, the evaluation of opening angles under the different flow rates conditions was achieved. In the pulsatile flow test, each leaflet's opening and closing behaviours were successfully reconstructed simultaneously at the high-frequency recording rate of 960fps. Therefore, the system developed in this study confirms the design evaluation method of an ePTFE valved conduit behaviour with leaflet structures interacting with local fluid dynamics in the vicinity of valves. Clinical Relevance- The system reveals the bulging sinus effects on ePTFE valve leaflet motion by the 3D reconstruction using multi-camera high-speed sequential imaging in vitro.

Targeting protein for Xenopus kinesin-like protein 2 (TPX2) is upregulated in various tumors, and several studies have demonstrated the role of TPX2 as a prognostic marker in cancer. However, the function of TPX2 in neuroblastoma (NB) has not been completely elucidated. In the present study, the clinical significance and functional role of TPX2 in NB was investigated. The Therapeutically Applicable Research to Generate Effective Treatments (TARGET)-NB dataset was used. A total of 43 patients with NB were enrolled in the present study as the validation set. After evaluating the prognostic role of TPX2, the combined predictive effect of TPX2 and MYCN proto-oncogene bHLH transcription factor (MYCN) gene amplification was assessed. Double immunofluorescence staining for TPX2 and N-Myc was used to analyze colocalization, and multiple cell function tests were performed by means of in vitro experiments to elucidate the functional role of TPX2 using RNA interference technology in NB cell lines. In both the TARGET-NB set and the validation set, it was found that upregulated of TPX2 was significantly associated with poor overall survival (OS) in patients with NB. The expression of TPX2 was higher in NB patients with MYCN gene amplification, and NB patients with high TPX2 expression and MYCN gene amplification had the poorest OS compared with patients with low TPX2 expression or a single copy of MYCN. In vitro experiments indicated that TPX2 positively regulated cell proliferation and the cell cycle, and promoted cell survival by increasing the resistance to apoptosis. The colocalization of TPX2 with N-Myc in NB cells and tissue was observed. The findings of the present study indicate that TPX2 plays an oncogenic role in NB development and may be a potential prognostic indicator in patients with NB.
RESUMO
OBJECTIVE: Eyes absent 4 (EYA4) is the causative gene of autosomal dominant non-syndromic hereditary hearing loss, DFNA10. We aimed to identify a copy number variation of EYA4 in a non-syndromic sensory neural hearing loss pedigree. FAMILY AND CLINICAL EVALUATION: A Japanese family showing late-onset and progressive hearing loss was evaluated. A pattern of autosomal dominant inheritance of hearing loss was recognized in the pedigree. No cardiac disease was observed in any of the individuals. METHODS: Targeted exon sequencing was performed using massively parallel DNA sequencing (MPS) analysis. Scanning of the array comparative genomic hybridization (aCGH) was completed and the copy number variation (CNV) data from the aCGH analysis was confirmed by matching all CNV calls with MPS analysis. Breakpoint detection was performed by whole-genome sequencing and direct sequencing. Sequencing results were examined, and co-segregation analysis of hearing loss was completed. RESULTS: We identified a novel hemizygous indel that showed CNV in the EYA4 gene from the position 133,457,057 to 133,469,892 on chromosome 6 (build GRCh38/hg38) predicted as p.(Val124_Pro323del), and that was segregated with post-lingual and progressive autosomal dominant sensorineural hearing loss by aCGH analysis. CONCLUSION: Based on the theory of genotype-phenotype correlation with EYA4 mutations in terms of hearing loss and comorbid dilated cardiomyopathy, the region of amino acids 124 to 343 is hypothesized not to be the pathogenic region causing dilated cardiomyopathy. Additionally, the theory of genotype-phenotype correlation about the prevalence of dilated cardiomyopathy is thought to be rejected because of no correlation of deleted amino acid region with the prevalence of dilated cardiomyopathy. These results will help expand the research on both the coordination of cochlear transcriptional regulation and normal cardiac gene regulation via EYA4 transcripts and provide information on the genotype-phenotype correlations of DFNA10 hearing loss.

Accumulating evidence suggests that overexpression of heat shock protein 47 (HSP47) increases cancer progression, and that HSP47 level in the tumor-associated stroma may serve as a diagnostic marker in various cancers. The present study aimed to evaluate whether HSP47 gene expression in colorectal cancer (CRC) tissues could be used to identify lymph node (LN) metastasis status preoperatively in patients with CRC. To do so, HSP47 gene expression was determined and its association with the clinicopathological characteristics of patients with CRC was analyzed. A total of 139 surgical specimens from patients with CRC and 36 patients with benign colonic disease undergoing surgery at Mie University Hospital were analyzed. HSP47 gene expression was determined by reverse transcription quantitative PCR using Power SYBR Green PCR methods. Expression level of HSP47 was significantly higher in CRC tissues compared with normal tissue from patients with benign colonic disease. Furthermore, high HSP47 expression was significantly associated with tumor progression, including high T stage, lymph node metastasis and venous invasion, and high TNM stage. High HSP47 expression may therefore serve as a novel predictive biomarker for determining patients with CRC and LN metastasis. According to Kaplan-Meier analysis, patients with high HSP47 expression level had significantly poorer overall survival than those with low HSP47 expression level. Furthermore, multivariate analyses identified HSP47 expression as an independent predictive marker for LN metastasis and poor overall survival in patients with CRC. In summary, the present study demonstrated that HSP47 expression may be considered as a novel biomarker for predicting LN metastasis status and prognosis in patients with CRC.
RESUMO
BACKGROUND: The aim of the present study was to investigate the efficacy and safety of double-balloon enteroscopy (DBE) in postoperative pediatric patients. METHODS: This was a retrospective analysis of pediatric patients 18 years and younger referred to Mie University Hospital. Twenty procedures in 11 children occurred postoperatively; 29 children (42 procedures) had not undergone surgery. RESULTS: Among postoperative patients, five DBE procedures were performed via the oral route, 12 via the anal route, and three via a stomal route. Among nonoperative patients, 14 DBE procedures were performed via the oral route and 28 via the anal route. Four postoperative patients and two nonoperative patients had difficult pleating via the transanal route because of adhesions or thickening of the intestinal wall resulting from inflammation (P = 0.02). Excluding patients with stenosis, the mean length of endoscopic insertion for transanal procedures was significantly shorter among postoperative patients than among nonoperative patients (73.6 cm vs 160.5 cm, P < 0.01). There were no major complications in either group. CONCLUSIONS: Insertion difficulty was encountered in postoperative pediatric patients. However, our findings indicate that DBE is a safe procedure in postoperative pediatric patients.

BACKGROUND: Our previous study identified methicillin-resistant Staphylococcus aureus (MRSA) colonization as an independent risk factor for neonatal surgical site infection. Here we introduce intraoral breast milk application (IBMA) during a fasting state to prevent MRSA colonization. We aimed to evaluate both the risk factors for MRSA colonization and the efficacy of IBMA in neonatal surgical patients. METHODS: A retrospective review was performed using admission data from 2007 to 2016. Neonatal patients who underwent surgery and were tested periodically for MRSA colonization were evaluated for an association between MRSA colonization and perinatal or perioperative factors. RESULTS: The overall incidence of MRSA colonization for the 159 patients enrolled in this study was 16.4%. Univariate analysis showed that MRSA colonization was significantly more frequent in the following patients: those with Down syndrome, those admitted on their day of birth, those in need of fasting immediately after birth, and those not receiving IBMA. Multivariate analysis showed that comorbid Down syndrome was an independent risk factor (hazard ratio: 4.6; 95% confidence interval: 1.2-19.5, P = 0.03) and implementation of IBMA was an independent preventive factor for MRSA colonization (hazard ratio: 0.4; 95% confidence interval: 0.1-0.9, P = 0.04). MRSA-positive patients admitted significantly earlier and stayed longer preoperatively than MRSA-negative patients. CONCLUSIONS: In neonates undergoing surgery, and patients with Down syndrome, early diagnosis after birth and a long waiting period before operation may be associated with MRSA colonization. Intraoral breast milk application may be beneficial for preventing MRSA colonization.

BACKGROUND: The predictive factors for chronic pouchitis after ileal pouch-anal anastomosis (IPAA) in pediatric-onset ulcerative colitis (UC) remain unclear. This study evaluated the predictive factors for chronic pouchitis after IPAA in patients with pediatric UC. METHODS: The data from 52 patients with pediatric-onset UC who underwent IPAA in Mie University Hospital were retrospectively reviewed. The endoscopy surveillance was performed yearly or at the timing of the symptom. Chronic pouchitis was defined as antibiotic-dependent/-refractory and relapsing cases. Potential predictors of chronic pouchitis were analyzed. RESULTS: During the first 5â¯years after IPAA, pouchitis was identified in 32.7%. Of these patients, 12 (70.6%) developed chronic pouchitis. The predictor of chronic pouchitis was a preoperative history of immunomodulator use before IPAA (pâ¯=â¯0.04). Life table analysis revealed that patients with chronic pouchitis tended to develop pouchitis earlier after IPAA than did patients without chronic pouchitis (pâ¯=â¯0.012). Receiver operating characteristic curve analysis showed that the occurrence of pouchitis within 15â¯months after IPAA surgery predicted the development of chronic pouchitis (sensitivity, 92%; specificity, 80%). CONCLUSION: In pediatric patients with UC, the predictive factors for chronic pouchitis are immunomodulator use and early occurrence of the first episode of pouchitis within 15â¯months after IPAA. LEVEL OF EVIDENCE: III.

PURPOSE: Establishment of evidence-based best practices for preventing surgical site infection (SSI) in neonates is needed. SSI in neonates, especially those with a low birth weight, is potentially life-threatening. We aimed to identify risk factors associated with SSI in neonates. METHODS: A retrospective review was performed using 2007-2016 admission data from our institution. Neonatal patients who were admitted to the neonatal intensive care unit and underwent surgery were evaluated for a relationship between development of SSI and perinatal or perioperative factors and methicillin-resistant Staphylococcus aureus (MRSA) colonization during hospitalization. RESULTS: One hundred and eighty-one patients were enrolled in this study. Overall SSI incidence was 8.8%. Univariate analysis showed that SSI was significantly more frequent in both patients with contaminated or dirty wound operations and patients with MRSA colonization during hospitalization. Both of these factors were identified as independent risk factors for SSI by multivariate analysis [hazard ratio (HR): 6.1, 95% confidence interval (CI) 2.0-19.9; HR: 3.3, 95% CI 1.1-10.4, respectively]. CONCLUSIONS: This study identified contaminated or dirty wound operations and MRSA colonization during hospitalization as risk factors for SSI in neonates. MRSA colonization may be a preventable factor, unlike previously reported risk factors.

BACKGROUND: In neonatal surgical patients requiring an enterostomy, there is no definitive recommendation regarding the ideal enterostomy location: at the edge of the primary incision or at a different incision. METHODS: We retrospectively reviewed 2005-2017 administration data in our institution. All neonatal patients who underwent contaminated or dirty wound laparotomy and enterostomy construction were evaluated regarding the enterostomy location, occurrence of postoperative incisional surgical-site infection (SSI) at the primary incision, and stoma-related complications. RESULTS: Patients were divided into two groups based on stoma location: at the primary incision (the same incision group: SI group, n = 16) or at another incision (different incision group: DI group, n = 23). We performed 2 jejunostomies, 13 ileostomies, and 1 colostomy in the SI group, and 4 jejunostomies, 18 ileostomies, and 1 colostomy in the DI group. One of 16 patients (6.3%) in the SI group and 2/23 patients (8.7%) in the DI group experienced superficial incisional SSI, with comparable SSI incidence between groups (p = 0.78). Every SSI did not result in stoma-related complications. CONCLUSIONS: Although the enterostomy location did not influence the incidence of laparotomy wound infection in this study, prospective studies are mandatory to fully assess the safety of enterostomy construction at the edge of the primary incision.

BACKGROUND/PURPOSE: The purpose of this study was to explore clinical characteristics and primary surgical diagnoses associated with in-hospital death in pediatric surgical patients admitted to the neonatal intensive care unit (NICU) of a tertiary hospital. METHODS: This retrospective study includes all patients admitted to our NICU for pediatric surgical diseases between January 2001 and December 2015. Univariate and multivariate binary logistic regression were performed to assess independent factors associated with in-hospital death. RESULTS: A total of 440 cases were included and 334 (83.5%) patients underwent one or more surgeries. Thirty six patients (8.2%) died while hospitalized in the NICU. The 5 most common surgical diagnoses were intestinal atresia/stenosis, anorectal malformation, congenital diaphragmatic hernia (CDH), esophageal atresia, and urinary system disorder. Necrotizing enterocolitis (NEC) had the highest mortality rate. Using logistic regression, in-hospital death was predicted by extremely low birth weight (ELBW) (odds ratio (OR)=6.594; P=0.006), CDH (OR=13.954; P<0.001), and NEC (OR=8.991; P=0.049). CONCLUSIONS: This study describes CDH, NEC, and ELBW are independent predictive factors associated with in-hospital death of pediatric surgical patients in our NICU. Novel approaches for those conditions are required to improve the survival. TYPE OF STUDY: Prognostic LEVELS OF EVIDENCE: II.

BACKGROUND: Anorectal malformation (ARM) is associated with a tethered spinal cord (TSC). Long-term functional outcome of untethering surgery for TSC in patients with ARM has not been well evaluated. METHODS: Patients aged 7 years and older who underwent repair of ARM and spinal magnetic resonance imaging from January 1995 to December 2008 were reviewed retrospectively. Untethering surgery was performed in all patients who were diagnosed with TSC, regardless of the presence or of neurological symptoms. Clinical symptoms reflecting anorectal, urinary, and lower limb function were compared between patients complicated with TSC (TSC group, n = 17) and those without TSC (non-TSC group, n = 14). RESULTS: The median age at functional evaluation was 11.7 and 12.9 years in the TSC and non-TSC groups, respectively (p = 0.52). Untethering surgery for TSC was performed at a median age of 1.3 years. Preoperative urinary and lower limb dysfunction, except for vesicoureteral reflux in the TSC group in one patient, was improved after surgical detethering. Current anorectal function was comparable between the groups. CONCLUSIONS: Long-term functional outcome in patients with ARM and TSC undergoing untethering surgery is equivalent to that in those without TSC. Prophylactic surgical detethering for patients with ARM and TSC can be a treatment of choice to maximize neurological functional outcome.

A 1-year-old boy with no underlying disorder presented with non-bilious vomiting since 4 days before admission. He was referred to our hospital and was diagnosed with a small bowel obstruction due to an intraabdominal tumor. Laparotomy revealed an intestinal volvulus with a soft and lobulated tumor arising from the mesentery. The resected tumor with a small part of the small bowel was diagnosed as lipoblastoma histologically. From a literature review, mesenteric lipoblastoma with an intestinal volvulus showed different characteristics such as greater frequency of vomiting and less frequency of abdominal mass as clinical symptoms, and the size of the tumor was smaller than that of the tumor without the intestinal volvulus.

Dysregulation pattern of microRNA-7 (miR-7) and the clinical significance of its expression in colorectal cancer (CRC) are unresolved. Here, we investigated the relationship between clinicopathological factors, including prognostic outcome, and miR-7 expression in CRC tissues. We analyzed miR-7 expression levels by real-time reverse transcription polymerase chain reaction in 210 colorectal tissues (196 CRCs and 14 normal mucosae from healthy volunteers). miR-7 expression levels were significantly up-regulated in CRC tissues compared to normal colorectal mucosae. Elevated miR-7 expression was significantly correlated with tumour depth, venous invasion, lymphatic invasion, lymph node metastasis, and liver metastasis. High miR-7 expression was significantly associated with poor overall survival in patients with CRC (p=0.010). Moreover, miR-7 expression was an independent prognostic factor in patients with CRC (hazard ratio=1.854, 95% confidence interval=1.016-3.540; p=0.044). miR-7 acts as an oncogene in CRC and is significantly associated with tumour progression and poor prognosis.

Dysphagia occurs in acute stroke patients at high rates, and many of them develop aspiration pneumonia. Team approaches with the cooperation of various professionals have the power to improve the quality of medical care, utilizing the specialized knowledge and skills of each professional. In our hospital, a multidisciplinary participatory swallowing team was organized. The aim of this study was to clarify the influence of a team approach on dysphagia by comparing the rates of pneumonia in acute stroke patients prior to and post team organization. All consecutive acute stroke patients who were admitted to our hospital between April 2009 and March 2014 were registered. We analyzed the difference in the rate of pneumonia onset between the periods before team organization (prior period) and after team organization (post period). Univariate and multivariate analyses were performed using a Cox proportional hazards model to determine the predictors of pneumonia. We recruited 132 acute stroke patients from the prior period and 173 patients from the post period. Pneumonia onset was less frequent in the post period compared with the prior period (6.9% vs. 15.9%, respectively; p = 0.01). Based on a multivariate analysis using a Cox proportional hazards model, it was determined that a swallowing team approach was related to pneumonia onset independent from the National Institutes of Health Stroke Scale score on admission (adjusted hazard ratio 0.41, 95% confidence interval 0.19-0.84, p = 0.02). The multidisciplinary participatory swallowing team effectively decreased the pneumonia onset in acute stroke patients.

BACKGROUND: Thoracoscopic repair is the preferred treatment for congenital diaphragmatic hernia (CDH); however, several complications, including visceral injury, hypercapnia, and a high incidence of recurrence, have been reported. The purpose of this study was to evaluate the efficacy of countermeasures against these complications at ensuring safe thoracoscopic repair. METHODS: Between January 2000 and December 2014, 40 patients with Bochdalek-type CDH were treated. Of these, 24 patients met the defined criteria for this study, 8 of whom underwent thoracoscopic repair beginning in January 2010 (TS group) and 16 underwent laparotomy before December 2009 (LT group). Perioperative variables and postoperative complications were compared between the groups. Countermeasures against adverse events in the TS group included an endoscopic surgical spacer to prevent visceral injury, intrapulmonary percussive ventilation to avoid hypercapnia, pausing CO2 insufflation to reduce tension during the repair, and prioritizing patch repair in cases of strong tension at the defect. RESULTS: Primary closure was performed in 4 of 8 cases in the TS and 11 of 16 cases in the LT group. There was no visceral injury or conversion to laparotomy in the TS group. The mean operative duration was significantly longer (212 vs. 115 min, respectively, p = 0.0001), and the mean blood loss was significantly less in the TS than in the LT group (1.0 vs. 10.1 mL, respectively, p = 0.01). The intraoperative minimum arterial pH and maximum pCO2 were similar between the groups. All patients survived, and none experienced recurrence. CONCLUSIONS: Our countermeasures to complications of thoracoscopic repair may contribute to safe outcomes equivalent to those of laparotomy in patients meeting our criteria.

BACKGROUND: Enterostomy may lead to fluid and electrolyte imbalance, or impaired absorption of nutrition followed by impairment of growth. This study aimed to clarify the effectiveness of enteral refeeding (ER) in premature and full-term neonates. METHODS: A retrospective database of all consecutive neonates who had enterostomy during 2000-2014 in a regional center was analyzed. Thirteen patients with ER (ER group) and 14 patients without ER (control group) were included. Detailed clinical data were evaluated with reference to the increment in body weight during ER. RESULTS: The ER group had a significantly higher rate in weight gain compared with the control group (P=0.0012), despite the gestational age (<37weeks: P=0.0012, ≥37weeks: P=0.029). ER starting at a lower body weight was also associated with a higher weight gain (P=0.0002). Moreover, univariate and multivariate analyses showed that only the ER procedure (P<0.0001) and birth weight (P=0.049) were significantly independent predictors of good weight gain. CONCLUSIONS: Using ER, low-birth-weight infants may have benefits, such as better acceleration of growth, than normal-birth-weight infants. We do not hesitate to perform ER, even in low-birth-weight neonates or those with low body weight, when starting ER.
