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.

PURPOSE: Surgical procedures for anorectoplasty for anorectal malformations (ARMs), particularly rectourethral fistula (RUF), depend on the institution. We investigated the diagnosis and treatment of RUF in male patients with ARMs in Japan using a questionnaire survey. METHODS: An online survey inquiring about the diagnosis and treatment (diagnostic modalities, surgical approaches, fistula dissection devices, and fistula closure techniques) of each type of ARM in male patients was conducted among institutional members of the Japanese Study Group of Anorectal Anomalies. Fisher's exact test was used to compare surgical methods between posterior sagittal anorectoplasty (PSARP) and laparoscopy-assisted anorectoplasty (LAARP). RESULTS: Sixty-one institutions (100%) completed the survey. LAARP was the preferred approach for high-type ARM (75.4%). PSARP was preferred for intermediate-type ARM (59.0%). Monopolar devices were most commonly used (72.1%) for RUF dissection. Blunt dissection was more frequent in the PSARP group (PSARP vs. LAARP: 55.6 vs. 20.0%, p < 0.005). Cystoscopy/urethroscopy to confirm the extent of dissection was used more frequently in the LAARP group (70.0% vs. 25.0%, p < 0.005). Clips and staplers were used more frequently in the LAARP group (p < 0.05). CONCLUSION: Distinct fistula management strategies for PSARP and LAARP were revealed. Further studies are needed to investigate the postoperative outcomes associated with these practices.

BACKGROUND: Peutz-Jeghers syndrome (PJS) is a rare disease characterized by the presence of hamartomatous polyposis throughout the gastrointestinal tract, except for the esophagus, along with characteristic mucocutaneous pigmentation. It is caused by germline pathogenic variants of the STK11 gene, which exhibit an autosomal dominant mode of inheritance. Some patients with PJS develop gastrointestinal lesions in childhood and require continuous medical care until adulthood and sometimes have serious complications that significantly reduce their quality of life. Hamartomatous polyps in the small bowel may cause bleeding, intestinal obstruction, and intussusception. Novel diagnostic and therapeutic endoscopic procedures such as small-bowel capsule endoscopy and balloon-assisted enteroscopy have been developed in recent years. SUMMARY: Under these circumstances, there is growing concern about the management of PJS in Japan, and there are no practice guidelines available. To address this situation, the guideline committee was organized by the Research Group on Rare and Intractable Diseases granted by the Ministry of Health, Labour and Welfare with specialists from multiple academic societies. The present clinical guidelines explain the principles in the diagnosis and management of PJS together with four clinical questions and corresponding recommendations based on a careful review of the evidence and involved incorporating the concept of the Grading of Recommendations Assessment, Development and Evaluation system. KEY MESSAGES: Herein, we present the English version of the clinical practice guidelines of PJS to promote seamless implementation of accurate diagnosis and appropriate management of pediatric, adolescent, and adult patients with PJS.

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.

A 71-year-old woman complained of nausea and anorexia. Laboratory tests revealed significant neutrophilia and immunoglobulin A-kappa type M proteinemia, as well as increased plasma cells on bone marrow examination. Furthermore, the serum granulocyte-colony stimulating factor (G-CSF) concentration was high at 160 pg/ml, and the colony stimulating factor 3 receptor (CSF3R)-T618I mutation was negative. Immunohistochemical (IHC) analysis of bone marrow specimens using the anti-G-CSF antibody revealed immunopositivity of some myeloma cells. The patient was diagnosed using G-CSF-producing myeloma and was treated with daratumumab, lenalidomide, and dexamethasone. Her treatment resulted in a very good partial response, with normalization of both serum G-CSF levels and neutrophil count. There have been a few cases of G-CSF -producing myeloma reported, and it has previously been reported as chronic neutrophilic leukemia with M proteinemia. According to previous reports, techniques such as serum G-CSF measurements, IHC with an anti-G-CSF antibody, and CSF3R gene mutation analysis are useful for differentiating G-CSF-producing myeloma. However, the clinical characteristics and long-term prognosis of G-CSF-producing myeloma remain unknown. Additional case gathering and investigations are required.

BACKGROUND: Pediatric ulcerative colitis (UC) is more challenging to treat than adult UC. Qing-Dai therapy is effective in adults but reports of its efficacy in children are unavailable. We conducted a questionnaire survey on Qing-Dai use among pediatric patients with UC in Japan to determine its efficacy and safety. METHODS: Questionnaires were sent to 31 high-volume centers treating pediatric patients with inflammatory bowel disease. The number of patients using Qing-Dai, short-term and long-term effects, and adverse events were assessed. A systematic review of studies on the efficacy and safety of Qing-Dai usage for UC was also performed. RESULTS: Overall, 29/31 facilities (93.5%) responded, Qing-Dai was used in 107 patients with UC, and 84/107 patients (78.5%) initiated treatment. Within 6 months, 81/101 (80.2%) patients had clinical remission, while 59/92 (64.1%) patients had no relapse and 29/92 (31.5%) experienced only one to two relapses yearly. Eighty-seven percent of the patients underwent regular follow ups for adverse events, among whom one patient was diagnosed with pulmonary arterial hypertension (PAH), five with enteritis, and one with headache. In the systematic review, the clinical remission rate was 50-80%, and PAH was observed in 14 of 1,158 patients (1.2%). CONCLUSIONS: Qing-Dai is highly effective in treating pediatric UC. However, Qing-Dai should be administered with caution as it may cause adverse events such as PAH.

The JAK2V617F mutation is a driver mutation of myeloproliferative neoplasms (MPNs). V617F allele burden is considered a risk factor for complications associated with MPNs and is a predictor of prognosis. In Japan, V617F allele burden has been measured in laboratory settings using the i-densyTM IS-5320 genetic analyzer with the quenching probe-Tm (QP-Tm) method. However, since 2020, allele-specific quantitative PCR (AS-qPCR) is being performed in clinical settings for measuring V617F allele burden. To investigate the clinical usefulness of the QP-Tm method in patients with MPNs, we evaluated the V617F allele burden measured by both the methods. A good correlation was observed between the V617F allele burden determined using QP-Tm and that determined using AS-qPCR (P<0.001, rs=0.952). The median mutant allele burden, as determined using the QP-Tm method, was significantly higher in patients with polycythemia vera than in those with essential thrombocythemia. The results of this study suggested that the QP-Tm method will continue to be useful clinical ancillary test for measuring V617F allele burden.

BACKGROUND AND AIM: The implementation rates of pediatric gastrointestinal endoscopy are increasing with advancements in the devices used and pediatricians' skills. As part of the Japan Pediatric Endoscopy Study Group, we aimed to investigate the rates of pediatric gastrointestinal endoscopy use and the associated adverse events through a nationwide survey. METHODS: A questionnaire was sent to 630 institutions in Japan. The numbers of pediatric gastrointestinal endoscopy cases and adverse events occurring during endoscopy, from April 2011 to March 2016, were investigated. RESULTS: Responses were obtained from 445 facilities. The total number of pediatric gastrointestinal endoscopies was 37 447 and that of endoscopic examinations was 32 219 (86.0%), with esophagogastroduodenoscopy accounting for 18 484 cases; ileal colonoscopy, 11 936; endoscopic retrograde cholangiopancreatography, 389; wireless capsule endoscopy, 897; and balloon-assisted enteroscopy, 513. The number of endoscopic treatments was 5228, followed by balloon dilatation (1703), foreign body removal (989), and polypectomy (822); 201 adverse events (0.54%) occurred, 79 of which presented during endoscopic examination (0.25%). Eight serious perforations were noted in 0.0054% and 0.025% of those undergoing esophagogastroduodenoscopy and colonoscopy, respectively. Overall, 122 adverse events (2.33%) occurred in association with endoscopic treatment. One case of cardiopulmonary arrest occurred because of accidental extubation. However, no deaths occurred. CONCLUSION: Endoscopic examinations had a slightly higher adverse event rate, because of an increase in endoscopic retrograde cholangiopancreatography and small intestine enteroscopy, than that reported in previous studies, but the adverse event rate of endoscopic treatment did not increase.

BACKGROUND AND AIM: Very early-onset inflammatory bowel disease is defined as inflammatory bowel disease diagnosed before 6 years of age. Very early-onset inflammatory bowel disease has various differential diagnoses, including primary immunodeficiency disorders, and is known to be resistant to conventional treatment. Therefore, global attention is required to manage this challenging condition. We conducted a retrospective epidemiological survey of the number of patients, final diagnosis, and examinations performed to diagnose very early-onset inflammatory bowel disease in Japan. METHODS: A primary questionnaire about the number of very early-onset bowel disease cases and its diagnosis was administered to 630 pediatric facilities nationwide in Japan. A secondary survey about the examinations performed to achieve diagnosis was sent to the facilities that responded to the first survey. RESULTS: The answering rate was 92.2% (581/630 facilities); 81 facilities had 225 very early-onset bowel disease patients undergoing their care during the past 68 months. Twenty-six patients (11.6%) were diagnosed with immunodeficiency-associated inflammatory bowel disease. The answering rate of the secondary survey was 70.4% (57/81 facilities). Colonoscopy, esophagogastroduodenoscopy, and small bowel imaging were performed for 99.4%, 67.5%, and 28.8% of patients, respectively. Genetic analysis was performed for 26.9% (43/160 patients) of patients, and 51.2% (22/43) of patients were diagnosed with immunodeficiency-associated inflammatory bowel disease. CONCLUSIONS: Approximately 40 patients are diagnosed yearly in Japan. Imaging studies, especially for small bowel lesions, can be challenging for this unique group of patients. However, a comprehensive approach including immunological and genetic analyses appears useful for diagnosing immunodeficiency-associated inflammatory bowel disease.

INTRODUCTION: The incidence of early-onset inflammatory bowel disease is increasing in Japan. OBJECTIVE: This study aimed to analyze the treatment and progress of early-onset inflammatory bowel disease. METHODS: This prospective survey evaluated the data of 43 patients aged <8 years who were diagnosed with inflammatory bowel disease (IBD) from the time of diagnosis to 36 months after registration. RESULTS: A total of 12 patients with Crohn's disease (CD), 21 with ulcerative colitis (UC), and 3 with unclassified IBD were enrolled. The mean disease onset age was 3 years and 7 months. Colon and anal lesions were present in 100 and 50% of patients with CD, respectively. Granulomas were detected in 5 patients (41.7%). Dietary elimination including elemental diet was performed in all patients. Eleven patients (91.7%) were in remission by initial induction therapy, and 72.7% maintained remission for 36 months. Three patients (14.3%) with UC had familial history, 71.4% had pancolitis-type UC, and 66.7% exhibited disease of moderate severity. Colectomy was performed in 4 patients (21.1%). Eighteen patients (85.7%) were in remission by initial induction therapy; however, only 15.8% maintained remission for 36 months. Anal complication was more prevalent in infantile-onset IBD than in childhood-onset IBD (p = 0.014). CONCLUSIONS: Among Japanese patients aged <8 years who were diagnosed with IBD, colitis-type disease was more common in CD and pancolitis was more common in UC. As the courses of several patients were severe, identifying primary immunodeficiency appears to be necessary to confirm background disease.

BACKGROUND: In 2019 we reported the results of a Japanese national survey designed to explore the views of adult gastroenterologists regarding transitional care for patients with childhood-onset inflammatory bowel disease (IBD). For the present study, we conducted a similar survey of pediatric gastroenterologists to compare the views of the two sets of specialists. METHODS: The survey conducted in 2019 involved 48 representative members of the Japanese Society for Pediatric Gastroenterology, Hepatology and Nutrition. They were contacted by conventional mail and their answers were not anonymized. Respondents who had already referred patients with IBD to adult gastroenterologists were asked in a questionnaire to rank the importance of specific statements on a Likert scale. RESULTS: The response rate was 79% and 29 (60%) of the respondents had experienced transitional care for patients with IBD. Transfer to adult care was considered by 90% of the respondents to be the ideal form of medical care for adolescents/young adults with IBD. However, 59% of the respondents had experienced some degree of difficulty when making referrals for such care. The majority of pediatric gastroenterologists considered that the ideal age for transfer was 18-22 years. Among the respondents, physicians at municipal hospitals considered that the presence of diseases other than IBD and a shortage of manpower were significantly more important issues than other practice settings. CONCLUSIONS: The present survey revealed that the general views regarding transitional care for IBD between pediatric and adult gastroenterologists were similar, except for the appropriate time for transfer. The results underline the importance of preparing a transition program appropriate to practice settings.

PURPOSE: To date, there is no compelling evidence of the optimal timing of surgery for congenital diaphragmatic hernia (CDH). This study aimed to establish the optimal timing of surgery in neonates with isolated left-sided CDH. METHODS: This multicenter cohort study enrolled 276 patients with isolated left-sided CDH at 15 institutions. Based on the timing of surgery, the patients were classified into four groups [< 24 h (G1), 24-47 h (G2), 48-71 h (G3), and ≥ 72 h (G4)]. The clinical outcomes were compared among the groups using a logistic regression model, after adjusting for potential confounders, such as disease severity. RESULTS: Multivariate analyses showed that G2 also had a lower mortality rate than the other groups. In mild and severe cases, there were no significant differences in mortality across the four groups. In moderate cases, G2 resulted in significantly increased survival rates, compared with G1. CONCLUSION: The study results suggest that surgery within 24 h of birth is not recommended for patients with moderate severity CDH, that there is no benefit in the delay of surgery for more than 72 h in mild severity CDH patients, and that there is no definite optimal time to perform surgery in severe cases of CDH.

PURPOSE: Predicting lethal pulmonary hypoplasia in infants with congenital diaphragmatic hernia (CDH) before extracorporeal membrane oxygenation (ECMO) initiation is difficult. This study aimed to predict lethal pulmonary hypoplasia in patients with CDH prior to ECMO. METHODS: This was a multicenter cohort study involving neonates prenatally diagnosed with isolated unilateral CDH (born 2006-2020). Patients who required ECMO due to respiratory insufficiency were included in this study. Patients who underwent ECMO due to transient disorders were excluded from analysis. Blood gas analysis data within 24 h of birth were compared between survivors and non-survivors. Predictive abilities were assessed for factors with significant differences. RESULTS: Overall, 34 patients were included (18 survivors and 16 non-survivors). The best pre-ductal PaO2 was significantly lower in non-survivors than in survivors (50.4 [IQR 30.3-64.5] vs. 67.5 [IQR 52.4-103.2] mmHg, respectively; p = 0.047). A cutoff PaO2 of 42.9 mmHg had a sensitivity, specificity, and positive predictive value of 50.0%, 94.4%, and 88.9%, respectively, to predict mortality. CONCLUSION: The best PaO2 within 24 h after birth predicted mortality following ECMO initiation. This should be shared to families and caregivers to optimize the best interests of the infants with CDH.

BACKGROUND: Although the etiology of pouchitis remains unknown, inflammatory cytokines are significantly associated with the pathogenesis of pouchitis. The cytokine responses that characterize inflammatory bowel diseases (IBD) are key pathogenic components of the disease. Although cytokine profiles in the colonic mucosa have been investigated in experimental colitis models or IBD patients, cytokine profiles in the ileal mucosa at colectomy have been rarely assessed. AIM: To assess the relationship between pouchitis and T helper (Th) cytokines in the ileal mucosa collected at the time of colectomy and pouch construction. METHODS: This retrospective study involved 68 consecutive patients from January 2004 to May 2011 who underwent ileal pouch-anal anastomosis for ulcerative colitis. Samples were obtained from the terminal ileum of resected specimens at time of total colectomy or subtotal colectomy. mRNA expression levels of Th cytokines (IFN-γ, IL-23A, IL-5, IL-13 and IL-17A) were determined. RESULTS: Forty of 68 patients (58.8%) developed pouchitis. There was no association between IL-23A expression levels and incidence of pouchitis (p = 0.301). Patients with elevated IFN-γ had a significantly higher incidence of pouchitis compared with low IFN-γ patients (p = 0.043). Univariate analysis demonstrated a total dose of prednisolone > 7000 mg administered before colectomy (p = 0.04) and high IFN-γ expression (p = 0.02) were significant risk factors for pouchitis onset. In multivariate analysis, elevated IFN-γ messenger(m)RNA levels were significantly associated with pouchitis onset (p = 0.03). CONCLUSION: IFN-γ expression in the normal ileal mucosa at the time of colectomy may be an important factor in the pathophysiology of pouchitis.

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.

For preterm and very low birthweight infants, the mother's own milk is the best nutrition. Based on the latest information for mothers who give birth to preterm and very low birthweight infants, medical staff should encourage and assist mothers to pump or express and provide their own milk whenever possible. If the supply of maternal milk is insufficient even though they receive adequate support, or the mother's own milk cannot be given to her infant for any reason, donor human milk should be used. Donors who donate their breast milk need to meet the Guideline of the Japan Human Milk Bank Association. Donor human milk should be provided according to the medical needs of preterm and very low birthweight infants, regardless of their family's financial status. In the future, it will be necessary to create a system to supply an exclusive human milk-based diet (EHMD), consisting of human milk with the addition of a human milk-derived human milk fortifier, to preterm and very low birthweight infants.

PURPOSE: This study aimed to elucidate the clinical characteristics of neonates with congenital diaphragmatic hernia (CDH) associated with pneumothorax and evaluate the risk factors for the development of pneumothorax. METHODS: A retrospective cohort study was conducted in the 15 institutions participating in the Japanese CDH Study Group. A total of 495 neonates with isolated CDH who were born between 2011 and 2018 were analyzed in this study. RESULTS: Among the 495 neonates with isolated CDH, 52 (10.5%) developed pneumothorax. Eighteen (34.6%) patients developed pneumothorax before surgery, while 34 (65.4%) developed pneumothorax after surgery. The log-rank test showed that the cumulative survival rate was significantly lower in patients with pneumothorax than in those without pneumothorax. Univariate analysis revealed significant differences between patients with pneumothorax and those without pneumothorax with regard to the best oxygenation index within 24 h after birth, mean airway pressure (MAP) higher than 16 cmH2O, diaphragmatic defect size, and need for patch closure. Multiple logistic regression analysis indicated that only the MAP was associated with an increased risk of pneumothorax. CONCLUSIONS: The cumulative survival rate was significantly lower in isolated CDH patients with pneumothorax than in those without pneumothorax. A higher MAP was a risk factor for pneumothorax in CDH patients.

BACKGROUND: The predictive factors for the development of pouchitis after ileal pouch-anal anastomosis (IPAA) in pediatric-onset ulcerative colitis (UC) have not been well investigated. The present study aimed to determine the predictive factors for the development of pouchitis after IPAA in the pediatric UC population. METHODS: The data from 54 patients with pediatric-onset UC who underwent IPAA in Mie University Hospital between 2000 and 2017 were retrospectively reviewed. A modified pouchitis disease activity index of ≥5 was defined as pouchitis. Potential preoperative, intraoperative, and postoperative predictors for pouchitis including various demographic and clinical variables were analyzed using Cox regression analysis, Students' t-tests, Mann-Whitney U tests, and Kaplan-Meier curves. The optimal cutoff value for continuous variables was determined using the receiver operating characteristic curve analysis. RESULTS: Pouchitis was identified in 17 (31.5%) patients within 5 y of follow-up. In multivariable analysis, the independent predictors for pouchitis were preoperative cumulative steroid dose of >10,000 mg (P = 0.0056) and >65% neutrophils just before IPAA (P = 0.032). Multivariate analysis revealed that the independent predictors of pouchitis were a total steroid dose of >10,000 mg (P = 0.0002) and a neutrophil percentage of >65% (P = 0.0078). No patient for whom both of these independent predictors were negative developed pouchitis, whereas >40% of patients who had one or both predictors developed pouchitis. CONCLUSIONS: In pediatric patients with UC, the predictive factors for pouchitis development are a greater cumulative total dose of steroids and a greater percentage of neutrophils before IPAA.
