Abstract
PURPOSE We explored factors affecting gastric emptying in neurologically impaired (NI) patients using the 13C-acetate breath test. METHODS Twenty-four NI patients were classified by the presence of gastroesophageal reflux disease (GERD), which was treated by fundoplication plus gastrostomy, or the absence of GERD, which was treated by gastrostomy alone, along with gastric malposition involving cascade stomach and organoaxial gastric volvulus (OGV). Gastric emptying parameters (GEPs), which were the emptying half time (T 1/2 , minute), the lag phase time (T lag , minute), and the gastric emptying coefficient (GEC), were measured before and after surgery. We evaluated the relationship between GEPs and GERD, gastric malposition, and surgical intervention. All data were expressed as the median (interquartile range). RESULTS The T1/2 and GEC of patients with OGV were significantly worse than in those without OGV before surgery (T1/2 with OGV: 241.3 [154.9, 314.3] vs. T1/2 without OGV: 113.7 [105.2, 151.4], p = 0.01, GEC with OGV: 3.19 [2.46, 3.28] vs. GEC without OGV: 3.65 [3.24, 3.90], p = 0.02). GERD and cascade stomach were not associ ated with GEPs. The GEPs of all NI patients showed no significant difference between before and after surgery. The surgical change in T1/2 (ΔT 1/2 ) in the patients with OGV was significantly lower than in those without OGV (ΔT1/2 with OGV: -47.1 [-142.7, -22.1] vs. ΔT1/2 without OGV: -3.78 [-26.6, 12.0], p = 0.03). CONCLUSION Stomach malposition, such as OGV, seems to affect gastric emptying and may be improved by surgi cal intervention.

Abstract
Aims The objective of this study was to evaluate the posttreatment effects of a school-based fluoride mouth-rinsing programme (FMR) on the prevalence of dental caries. Methods We included 364 newly enrolled university students aged 20 to 25 years who were not in any FMR and 187 students who had previously participated in such programmes. We calculated the prevalence of dental caries in permanent teeth and the mean decayed, missing, and filled surfaces (DMFS) according to sex, age, participation in FMR, and dental health behaviours. A multivariate logistic regression model was used to analyse the association between dichotomous variables (caries present or absent) and demographic data, participation in FMR, and dental health behaviours. Results The difference in the prevalence of dental caries in permanent teeth between the subjects who participated in the FMR (51.3%) and those who did not (64.5%) was statistically significant. There were 39.6% fewer DMFS in the subjects who participated in the FMR at least during elementary school. The multivariate logistic regression model analysis demonstrated that subjects who participated in the FMR at least during elementary school were protected against dental caries as compared to those who did not. Age and sex were risk predictors of dental caries in adults, whilst other variables were not associated with dental caries. Conclusions Participation in an FMR at least during elementary school is a predictor for the reduction in the prevalence of dental caries in permanent teeth.

Abstract
AIM The creatinine-to-cystatin C ratio (CCR) has been acknowledged as a potential marker of muscle mass. The purpose of the present study was to evaluate the relationship between CCR and nutritional status in a bioelectrical impedance analysis (BIA) of patients with severe motor and intellectual disabilities (SMID). METHODS This study included 39 patients with SMID (17 males, 22 females) over 16 years of age were included retrospectively. CCR was calculated as serum creatinine (mg/dL)/cystatin C (mg/L) × 10. The BIA parameters such as the phase angle (PhA), fat free mass (FFM), appendicular skeletal muscle mass (ASM) and appendicular skeletal muscle mass index (ASMI) values were measured using BIA. Correlation analyses between CCR and the BIA parameters were conducted. RESULTS The mean CCR is 4.47 ± 1.34. Significant positive relationships between CCR and FFM, PhA, ASM, ASMI were identified (r = 0.3373, p = 0.0357. r = 0.4273, p = 0.0093. r = 0.5008, p = 0.0012. r = 0.4706, p = 0.0025 and r = 0.4751, p = 0.0022, respectively). CONCLUSIONS The study indicated that CCR in the patients with SMID is a useful parameter that allows for the muscle mass to be estimated easily and accurately. This means that evaluating CCR could be used as a simple and important screening tool for PhA, FFM and muscle mass.

Abstract
PURPOSE A nationwide survey was conducted to investigate the current status of pediatric gastroesophageal reflux disease (GERD) in Japan, with special reference to the characteristics of intractable GERD. METHODS Data were collected using a questionnaire from facilities specializing in the treatment of pediatric GERD in Japan. Intractable GERD was defined as follows: I, no symptomatic improvement after 8 weeks of optimal medical treatment (OMT) plus fundoplication; II, no symptomatic improvement after 8 weeks of OMT and with no indications for fundoplication; and III, no symptomatic improvement after surgery without OMT. RESULTS We collected data from 3,463 pediatric patients with GERD from 91 institutions, and 81 satisfied the definition of intractable GERD. Additional clinical information was obtained from 56 patients, and 41 represented cases of definite intractable GERD. The main underlying disorders included neurological impairment (NI), esophageal atresia (EA), and congenital heart disease (CHD), which altogether accounted for 85% of patients. Of the 41 patients, 33 received fundoplication, and the remaining 8 received medical treatment alone because surgery was considered unsuitable. CONCLUSIONS The nationwide survey revealed that pediatric intractable GERD is rare in Japan. Three main underlying disorders-NI, EA, and CHD-were implicated in the majority of cases of intractable GERD.

Abstract
BACKGROUND Members of the Japanese Biliary Atresia Society were surveyed using questionnaires that assess their current practice regarding postoperative pharmacotherapy for outpatients with biliary atresia (BA). METHODS In September 2018, questionnaires were sent to 100 member institutions of the Japanese Biliary Atresia Society. Questionnaires included the number of BA outpatients per institution and pharmacotherapy for outpatients with native liver. Pharmacotherapies were categorized into antibiotics, cholagogues, hepatoprotective agents, branched-chain amino acid supplement, Japanese Kampo medicine, probiotics, laxative, glycerin enema, and "others." In each category, the questionnaires asked about the medicine's details and the time of withdrawal of administration. RESULTS Responses were collected from 58 of the 100 institutions. Fifty-four institutions (94.7%) had prescribed one or more medicines as postoperative pharmacotherapy, and three institutions (5.3%) did not prescribe any medicines. Fifty-three institutions (93.0%) had prescribed ursodeoxycholic acid (UDCA), and 32 (60.4%) of these continued prescribing UDCA as long as the condition of patients remained unchanged. Twenty-nine (50.9%) had prescribed Japanese Kampo medicines ("Inchinkoto" in all cases). Twenty-four (42.1%) had prescribed antibiotics, mainly trimethoprim-sulfamethoxazole, in 21 (87.5%). Twenty-three (40.4%) had prescribed probiotics. CONCLUSIONS There were many variations of pharmacotherapy in BA outpatients with native liver in Japan, including antibiotic, probiotic, and Inchinkoto prescriptions. Of the various drugs, the most commonly administered was UDCA.

Abstract
BACKGROUND A questionnaire survey was conducted to clarify whether surgical treatments performed by a pediatric surgeon improve the quality of life (QOL) of caregivers (medical doctors, nurses, physical therapists, and nursery teachers) supporting neurologically impaired (NI) patients who work at specialized institutions. METHODS The questionnaire survey was conducted with caregivers who cared for NI patients who underwent an operation at the Department of Pediatric Surgery, Kurume University Hospital. Quality-of-life related responses concerning the change of care after surgical procedures in NI patients were collected in addition to the background data related to caregivers and the surgical procedures performed for them. Degrees of difficulty in caring for NI patients and of the caregivers' own QOL postoperatively were also compared. RESULTS There were 192 valid responses. The majority of responses were from females and nurses aged in their 40s and 50s. The surgical procedure performed most often in the NI patients was gastrostomy. Of the respondents, 77% answered that the postoperative care became easier. The degrees of difficulty in caring for NI patients and the caregivers' own QOL were significantly higher and lower, respectively, among physical therapists compared with caregivers in other occupations. Moreover, the QOL in respondents with factors related to a longstanding relationship with NI patients was significantly higher compared with the respondents without them. CONCLUSION This survey indicated that surgical procedures for NI patients might contribute to improved QOL for the caregiver by reducing the difficulty of caring for NI patients.

Abstract
BACKGROUND Neurological impairment (NI) is responsible for most conditions that require a permanent gastrostomy tube. The present study assessed the occurrence of short- and long-term complications after video-assisted gastrostomy (VAG) in patients with NI. METHODS The incidence of short- (<6 months) and long-term (over 2 years) complications of VAG were analyzed in a retrospective study. The differences between the incidence of the complications of VAG according to the age at surgery (≤15 years vs. ≥16 years) were also evaluated. The short- and long-term complications observed were granulation tissue formation, infection requiring antibiotic treatment, skin problems, perigastrostomy leakage, vomiting, accidental tube dislodgement, dumping syndrome, ileus, and peritonitis. RESULTS Eighty-two patients were evaluated for short- and long-term complications. The long-term complication rate was significantly lower than the short-term complication rate (P = 0.0026). Onodera's prognostic nutritional index before VAG in patients with long-term complications was significantly lower than in patients without such complications (P = 0.046). The incidence of long-term granulation tissue formation, infection, and vomiting were significantly lower than those of similar short-term complications. Long-term skin problems were associated with short-term skin problems (odds ratio: 18.95; 95% confidence interval: 4.53-92.98; P < 0.001). The number of patients ≥16 years old with short- and long-term skin problems was significantly higher than in patients ≤15 years old (P = 0.0014 and P = 0.0073, respectively). CONCLUSIONS The incidence rate of granulation tissue formation and infection after VAG were lower in the long term than in the short term. However, patients ≥16 years old presented with persistent complications.

Abstract
OBJECTIVE To determine if the administration of the Japanese herbal medicines Inchinkoto (ICKT) and Saireito (SRT) ameliorate hepatic fibrosis and derangement of hepatocyte aquaporins (AQPs) following bile duct ligation (BDL) in a rat model of obstructive cholestasis. MATERIALS AND METHODS Five groups of Wistar rats were used, and the groups included sham surgery (Sham group), BDL with no treatment (NT group), BDL plus ICKT (ICKT group), BDL plus SRT (SRT group), and BDL plus ICKT and SRT (SRT/ICKT group). Each herbal medicine was administered at 1 g/kg/day on the first postoperative day. The serum levels and various clinical markers were measured with real-time polymerase chain reaction. Staining was used to evaluate the degree of fibrosis and the inflammatory responses. RESULTS Serum aspartate aminotransferase and alanine aminotransferase in the ICKT and SRT/ICKT groups were significantly lower than those in the NT group. NF-κB mRNA expression was significantly decreased in the ICKT group and the SRT/ICKT group compared with the NT group. AQP9 mRNA expression was significantly increased in the ICKT group and the SRT/ICKT group compared with the NT group. The degree of Masson's trichrome staining in the SRT/ICKT group was significantly lower than that in the NT group. The degree of NF-κB staining in the SRT/ICKT group was significantly lower than that in the NT, ICKT, or SRT group. CONCLUSIONS The postoperative administration of ICKT and SRT induced synergistic beneficial effects, resulting in the reduction of hepatic fibrosis via mechanisms involving the inhibition of NF-κB expression and the improvement of AQP9 downregulation.

Abstract
A 7-year-old girl was referred to our hospital with a suspected right-sided indirect inguinal hernia. An egg-sized elastic, non-painful mass was palpated in the right inguinal region. Preoperative CT demonstrated a 30-mm simple cystic mass in the right internal inguinal canal, which we diagnosed as an abdominal cyst of the canal of Nuck. Laparoscopy revealed that the abdominal cystic component was ruptured, so we performed Pott's procedure. However, the patient's right groin swelled on postoperative day 3, necessitating re-operation. The patient's symptoms recurred again after 3 months, despite having had two surgical repairs. In the third operation, a right-sided femoral hernia was confirmed and repaired via external and laparoscopic approaches. To the best of our knowledge, there have been no reports on the combination of femoral hernia and cyst of the canal of Nuck in children. A laparoscopic approach was useful for obtaining a definitive diagnosis and conducting a safe and secure surgical repair.

Abstract
Pigment epithelium-derived factor (PEDF) is one of the adipocytokines with multifaceted functions, which may serve a role in the development of various types of cardiometabolic disorders. Advanced glycation end products (AGEs) have been shown to contribute to numerous aging-associated disorders, such as cancer. However, it remains unclear whether and how PEDF exerts antitumor effects in AGE-exposed human breast cancer MCF-7 cells, and therefore this was explored in the present study. NADPH oxidase activity was measured with luciferase assay, while gene and protein expression levels were evaluated with quantitative PCR and western blot analysis, respectively. AGEs significantly increased NADPH oxidase-driven superoxide generation, cytochrome b-245 β chain (gp91phox) and receptor for AGE (RAGE) mRNA expression, proliferation, mRNA and protein expression levels of vascular endothelial growth factor (VEGF), and matrix metalloproteinase (MMP)-9 mRNA expression in MCF-7 cells, all of which were dose-dependently inhibited by PEDF. Neutralizing antibody against laminin receptor (LR-Ab) significantly blocked these beneficial effects of PEDF in AGE-exposed MCF-7 cells. Furthermore, as in AGE-treated cells, PEDF dose-dependently inhibited the NADPH oxidase-driven superoxide generation, gp91phox, RAGE and MMP-9 mRNA expression, proliferation, mRNA and protein expression levels of VEGF in non-treated control MCF-7 cells, and these effects were also reversed by LR-Ab. LR levels were not affected by the treatment with AGEs, PEDF or LR-Ab. The present study suggested that PEDF may exert antitumor effects in AGE-exposed breast cancer cells by suppressing NADPH oxidase-induced ROS generation and VEGF and MMP-9 expression via interaction with LR. Since PEDF expression is decreased in breast cancer tissues, pharmacological upregulation or restoration of PEDF may inhibit the growth and metastasis of breast cancer.

Abstract
BACKGROUND Apart from Kasai's procedure, liver transplantation (LTx) has dramatically improved the outcome of children with biliary atresia (BA). However, de novo malignancy has been reported to be one of the major causes of late mortality after LTx among adults. We report a rare case of de novo gastric cancer developing after LTx for BA received during childhood. CASE PRESENTATION A 21-year-old male patient who had undergone LTx for BA at age 2 years occasionally visited our outpatient clinic due to symptoms of epigastric pain and dysphagia. Endoscopic examination and computed tomography revealed advanced gastric cancer at the gastroesophageal junction with multiple liver metastases. Despite systemic chemotherapy, the disease progressed, resulting in patient's death 2 years after the diagnosis. CONCLUSIONS De novo malignancy in the absence of post-transplant lymphoproliferative disease is rare in pediatric patients who received LTx. To the best of our knowledge, no report has been available on the development of gastric cancer after LTx for BA during childhood. Primary physicians should therefore establish a follow-up plan for patients receiving LTx for BA considering the potential for the development of de novo malignancy, including gastric cancer, despite its rarity.

Abstract
Background/Aims This study aims to evaluate the presence of laryngopharyngeal reflux (LPR) and to investigate the use of hypopharyngeal baseline impedance (BI) for assessing swallowing dysfunction and gastroesophageal reflux disease (GERD) using hypopharyngeal multichannel intraluminal impedance and pH (HMII-pH) monitoring in neurologically impaired patients (NIPs). Methods The study population in this retrospective study comprised 20 NIPs (mean age, 36.1 ± 15.0 years; age range, 13-64 years) who underwent multichannel intraluminal impedance and pH (MII-pH), HMII-pH, and laryngoscopy using the Hyodo scoring method from December 2016 to April 2019. The MII-pH and HMM-pH parameters were compared in the NIPs, whereas hypopharyngeal BI values were compared between NIPs with ≥ 5 and < 5 in Hyodo scores. Correlations between the hypopharyngeal BI values and the Hyodo score were analyzed using Spearman’s correlation coefficient. A receiver operator characteristic curve was created to determine the optimum cut-off of hypopharyngeal BI value to discriminate SD. Results Three NIPs were diagnosed with pathological LPR and GERD by the HMII-pH monitoring. No significant differences in parameters were observed between MII-pH and HMII-pH monitoring. The correlation analysis demonstrated a significant negative correlation between the hypopharyngeal BI values and Hyodo scores. The optimal cutoff value for hypopharyngeal BI was 1552 Ω. Conclusions This study demonstrated the usefulness of HMII-pH monitoring in identifying NIP with pathological LPR. Considering the difficulties in performing examinations in NIPs, HMII-pH monitoring may be a potentially useful technique for the simultaneous evaluation of swallowing dysfunction, LPR, and GERD in NIP.

Abstract
OBJECTIVE Interaction of advanced glycation end products (AGEs) with the receptor RAGE plays a role in diabetic nephropathy. However, effects of RAGE-aptamer on tubular damage remain unknown. We examined whether RAGE-aptamer inhibited tubular damage in KKAy/Ta mice, obese type 2 diabetic mice with insulin resistance. MATERIALS AND METHODS Male 8-week-old KKAy/Ta mice received continuous intraperitoneal infusion of either control-aptamer or RAGE-aptamer for 8 weeks. Blood biochemistry and blood pressure, and urinary N-acetyl-β-D-glucosaminidase (NAG) activity and albumin excretion levels were monitored. Kidney and adipose tissue samples were obtained for immunohistochemical analyses. RESULTS Although RAGE-aptamer did not affect blood glucose, blood pressure, body weight, or serum creatinine values, it significantly inhibited the increase in urinary NAG activity and HOMA-IR in diabetic mice at 12 and 16 and at 16 weeks old, respectively. Furthermore, compared with control-aptamer-treated mice, renal carboxymethyllysine, RAGE, and NADPH oxidase-driven superoxide generation were significantly decreased in RAGE-aptamer-treated mice at 12 weeks old with subsequent amelioration of histological alterations in glomerular and interstitial area, while adipose tissue adiponectin expression was increased. CONCLUSION Our present results suggest that RAGE-aptamer could inhibit tubular injury in obese type 2 diabetic mice partly by suppressing the AGE-RAGE-oxidative stress axis and improving insulin resistance.

Abstract
Introduction Gastrointestinal stromal tumor (GIST) is rare neoplasms of the gastrointestinal tract associated with high rates of malignant transformation. GIST has been found largely in the stomach, small bowel, colon and rectum, and esophagus, but about 5% are found in other locations. We herein report a 56-year-old woman with a GIST in perforated Meckel's diverticulum. After encountering this patient, a review of the literature found reports of 18 similar patients. Case presentation A 56-year-old woman diagnosed with galactosialidosis (β-galactosidase-neuraminidase deficiency) presented with vomiting. On contrast-enhanced computed tomography, peritonitis due to perforation of the intestine was diagnosed based on the free air and dilated loop of the small bowel. Laparotomy revealed perforation of Meckel’s diverticulitis located 50 cm from the ileocecal valve. Partial resection of the ileum, including the diverticulum, and end-to-end anastomosis of the small intestine were performed. Regarding the pathological findings, the edge of the diverticulum wall consisted of a solid mass measuring 1.0 cm in size, and the tumor cells were spindle-shaped with 1 mitosis present per 50 high-power fields. The diagnosis was established as GIST of the Meckel's diverticulum. The postoperative period was uneventful. Follow-up at two years revealed no evidence of recurrence. Conclusion GIST in perforated Meckel's diverticulum is very rare. The potential for the coexistence of GIST or other tumor should be considered in the treatment of perforated Meckel's diverticulum.

Abstract
BACKGROUND Lipomatous tumors are the most common type of soft-tissue tumors. Benign lipomatous tumors are lipomas and lipoblastoma. We herein report a case of benign mesenteric lipomatous tumor and the largest collection of known benign mesenteric lipomatous tumors in children in the literature. CASE PRESENTATION A 3-year-old girl presented with repeated dull abdominal pain and left abdominal mass swelling. On a physical examination, the child had a soft, moderately distended left abdomen that was not tender when palpated. Computed tomography and magnetic resonance imaging demonstrated a large fatty mass within the mesentery, measuring approximately 8 × 6 cm. The mass extended from the right upper quadrant to the lower pole of the kidneys. Laparotomy with resection of the mesenteric tumor was performed under general anesthesia. A well-capsuled tumor was a soft, yellow mass and found loosely attached to the mesenterium of the ileum. A histopathological examination demonstrated the lobular proliferation of mature adipocytes. Atypical lipoblasts were not seen. These features are compatible with benign lipomatous tumor, such as lipoma or lipoblastoma with maturation. CONCLUSION In conclusion, benign mesenteric lipomatous tumors tend to be large in size over 10 cm in longitudinal length. However, resection is well tolerated in the vast majority of cases with benign post-operative courses.

Abstract
Biliary atresia (BA) is a devastating cholestatic disorder of infants that presents during the first several months after birth due to an idiopathic obstruction to the bile flow. Without prompt diagnosis, Kasai portoenterostomy, and deliberate follow-ups, the resulting cholestasis leads to progressive hepatic failure. Oxidative stress is an abnormal phenomenon inside cells or tissues caused by a disturbance in the reactive oxygen species (ROS). We aimed to measure perioperative ROS in BA patients.Data are presented as median (25th, 75th percentiles). We evaluated 15 BA patients (age 55 [48, 69] days) and measured ROS; serum superoxide dismutase (SOD), urinary 8-iso prostaglandin F2α (8-iso-PGF2α) and 8-hydroxy-2'-deoxyguanosine (8-OHdG) preoperatively and 30 days later to compare values with serum liver function tests and histologic grades of liver cholestasis. For compared BA patients, 4 normal subjects as control group (age 55 [27, 75] days) measured ROS and serum liver function tests.In BA patients, the preoperative serum SOD was 6.1 IU/mL (4.7, 7.2), urinary 8-iso-PGF2α was 1969 pg/mg Cre (1697, 2374), and urinary 8-OHdG was 37.1 ng/mg Cre (33.1, 53.7). At the postoperative day 30, the serum SOD was 5.2 IU/mL (4.2, 6.7), urinary 8-iso-PGF2α was 1761 pg/mg Cre (1256, 3036), and urinary 8-OHdG was 42.1 ng/mg Cre (29.65, 72.64). In ROS, there were no significant differences between the 2 periods. In control group, urinary 8-iso-PGF2α was significantly lower than that in preoperative BA patient group. However, other ROS were not significant differences between control group and BA patient group. The concentration of urinary 8-iso-PGF2α was positively correlated with total bilirubin and direct bilirubin levels (preoperatively: r = 0.6921, P = .0042 and r = 0.6639, P = .007, postoperatively: r = 0.6036, P = .0172 and r = 0.6464, P = .0092, respectively). The preoperative ROS were not correlated with histologic grades of liver cholestasis. Various factors such as liver inflammation, lipid malabsorption, and tissue disorders due to jaundice might affect the antioxidant activity and elevated urinary 8-iso-PGF2α. However, at least until 30 days later, urinary 8-OHdG as oxidative DNA damage might persist after the operation whether the cholestasis improved or not.

Abstract
BACKGROUND The aim of this study was to determine the frequency and nature of pediatric blunt chest-abdominal injuries (BCAIs) and to summarize their management, ranging from non-operative management (NOM), with or without angioembolization (AE), to surgical treatment. METHODS This retrospective study included patients admitted to our hospital for BCAIs from January 1996 to December 2017. The age, injury pattern, organs of injury, outcome, and treatment were summarized. RESULTS One hundred and thirty-two patients (98 males, 34 females, mean age 7.68 years ± 3.58, range 1-15 years) were included in the study. Their injuries resulted from motor-vehicle traffic incidents (n = 60), single-bicycle injuries (n = 16), falls (n = 33), sports (n = 10), assault (n = 6), abuse (n = 3), and others (n = 4). There were no injured organs in 31 cases, while there were 130 injured organs in 101 cases, including the liver (n = 42), spleen (n = 35), lung (n = 23), kidney (n = 13), intestine (n = 10), pancreas (n = 5), and adrenal gland (n = 2). Angiography (AG) was performed in 20 cases, and NOM with AE was performed in 16 cases, including 17 organs (liver injury [n = 9], splenic injury [n = 5], and kidney injury [n = 4]). Surgical treatment was performed in eight cases (splenic injury in one, pancreas injury in one, and intestinal injury in six). NOM without AE was performed in the other cases. CONCLUSIONS The management of organ injury must take into consideration the management of integrated bleeding. It is recommended that children with severe organ injury are treated in dedicated trauma centers in which AE is available.

Abstract
BACKGROUND Various techniques are applied in laparoscopic surgery for the treatment of urachal remnants, which are less invasive and associated with lower morbidity. We herein report a case series in which we treated urachal remnants and medial umbilical ligaments using a laparoscopic approach. CASE PRESENTATION From 2015 to 2019, seven patients (male, n = 5; female, n = 2) with a urachal remnant were treated by laparoscopic surgery in our institute. Five boys and two girls with a median age of 11 years (range 10-15 years) were enrolled in this series. The clinical results of laparoscopic treatment, the perioperative records, and the pathologic results were evaluated. The operation was performed with the use of three ports and an EZ access® (Hakko Medical, Nagano, Japan), which is a silicon cap for the wound retractor (Lap Protector®, Hakko Medical, Nagano, Japan). The removal of the urachal remnant and medial umbilical ligaments was completed with a median operative time of 92 min (range 69-128). The median hospital stay after surgery was 4 days (range 2-5). No patients developed intra-postoperative complications or recurrence. CONCLUSIONS Although our data are preliminary, complete laparoscopic removal of symptomatic urachal remnants and medial umbilical ligaments was a safe and effective minimally invasive approach, with better cosmetic outcomes.

Abstract
PURPOSE We investigated the relationship between Krickenbeck score (KS) and fecoflowmetry (FFM) parameters and assessed the characteristics of this new questionnaire test by comparing Kelly's clinical score (KCS) in pediatric patients with anorectal surgery for anorectal malformation (ARM) and Hirschsprung's disease (HD). METHODS We enrolled pediatric patients who underwent anorectal surgery for ARM or HD. Bowel function was assessed with KS and KCS thereafter, FFM and anorectal manometry (AM) were conducted. Patients were divided into subgroups according to each parameter of the scoring system and each FFM parameter was compared among the KCS or KS subgroups, respectively. Moreover, correlation analyses were conducted between FFM and AM parameters. RESULTS The comparison of FFM parameters among the subgroups of KCS showed that Fmax in the KCS staining 2 group was significantly higher than that in KCS staining 1 group and the Fmax in KCS sphincter squeeze 1 group was significantly higher than that in KCS sphincter squeeze 0 group. Moreover, Fmax in the KCS "good" group was significantly higher than that in the KCS "fair" group. The comparison of FFM parameters among the subgroups of KS parameters showed that TR in the no soiling group was significantly higher than that in the KS grade 2 soiling group. FFM and AM parameters showed a significant positive correlation between Fmax and voluntary squeezing anal pressure. CONCLUSION FFM clarified the different characteristics of two scoring systems, namely, KCS reflects the anal sphincter performance, whereas the KS soiling score might reflect the tolerance and evacuation ability.

Abstract
Pigment epithelium-derived factor (PEDF) is one of the serine protease inhibitors with multifunctional properties, which is produced by various types of organs and tissues. There is an accumulating body of evidence that PEDF plays an important role in the maintenance of tissue homeostasis. Indeed, PEDF not only works as an endogenous inhibitor of angiogenesis, but also suppresses oxidative stress, inflammatory and thrombotic reactions in cell culture systems, animal models, and humans. Furthermore, we, along with others, have found that PEDF inhibits proliferation of, and induces apoptotic cell death in, numerous kinds of tumors. In addition, circulating as well as tumor expression levels of PEDF have been inversely associated with tumor growth and metastasis. These observations suggest that supplementation of PEDF proteins and/or enhancement of endogenous PEDF expression could be a novel therapeutic strategy for the treatment of cancer. Therefore, in this paper, we review the effects of PEDF on diverse types of cancer, and discuss its therapeutic perspectives.

Abstract
Oral nutritional supplements (ONS) are multi-nutrient products used to increase the energy and nutrient intakes of patients. The aim of this study was to examine whether or not the adherence of patients varies according to their receiving prescription or over-the-counter ONS. Data were obtained from an online cross-sectional survey conducted with patients in Japan. A total of 107 patients who matched the inclusion criteria for the prescription ONS group and 148 who matched the criteria for the over-the-counter ONS group were further analyzed. In the prescription and over-the-counter ONS groups, the main medical reason for ONS consumption were “malnutrition” (48 patients [44.9%] vs. 63 patients [42.6%] p = 0.798], “frailty” (29 patients [27.1%] vs. 36 patients [24.3%] p = 0.663) and “aging” (25 patients [23.4%] vs. 30 patients [20.3%] p = 0.644). The proportion of “No particular disease” for prescription ONS consumption was significantly lower than that for over-the-counter ONS (6 patients [5.6%] vs. 24 patients [16.2%] p = 0.001). The body mass index of the prescription ONS group was significantly higher than that of the over-the-counter ONS group (21.1±4.38 kg/m2 vs. 19.9±3.75 kg/m2, p = 0.0161). In the prescription ONS group, all patients were given medical advice by doctors or registered dietitians. In contrast, in the over-the-counter ONS group, only 46 patients (31.1%) were given advice by doctors or registered dietitians (p<0.001). In the prescription ONS group, ONS was taken significantly more times and for a longer duration than in the over-the-counter ONS group (p<0.0001). However, among patients given advice by doctors or registered dietitians, there were no significant differences between the groups. Greater support by the medical team is still needed in order to maximize adherence to supplementation, especially concerning the calories, timing and period, so that benefits can be achieved and sustained.

Abstract
Background Biliary atresia (BA) cases are generally not associated with congenital abnormalities. However, accurate diagnosis of BA is often challenging because the histopathological features of BA overlap with those of other pediatric liver diseases and rarely overlap with those of other genetic disorders. We experienced a rare case of BA with the histopathological finding of bile duct paucity, a gene mutation in KDM6A, and KS-like phenotypes. Case presentation A male baby was diagnosed with biliary atresia by intraoperative cholangiography at 4 days of age, and histological examination following a liver biopsy revealed a paucity of bile ducts and several typical clinical findings of Alagille syndrome. However, Alagille syndrome was ruled out after neither JAG1 nor NOTCH2 gene mutations were identified. Whole-exome sequencing on DNA from his parents was additionally performed to examine other possible syndromic disorders, and a mutation was identified in KDM6A. However, Kabuki syndrome was not diagnosed as a result. The histological finding of interlobular bile duct paucity and the genetic mutation in KDM6A, as well as several clinical findings consistent with Alagille syndrome or Kabuki syndrome, made it difficult to confirm the diagnosis of BA. Conclusions Based on the interesting findings of the present case, we hypothesized that KDM6A is associated with hepatic malformations via a connection with the Notch signaling pathway.

Abstract
Multichannel intraluminal impedance-pH measurements (MII-pH) are useful for evaluating acid and non-acid gastroesophageal reflux (GER). However, the use of MIH-pH is not yet established in Japan. The Japanese Pediatric Impedance Working Group (Japanese-PIG) convened to devise a standard protocol for MII-pH in Japanese children. The expert members of the Japanese-PIG collected data on pediatric MII-pH from the relevant literature in English, including the standard protocol of MII-pH presented by the European PIG, and the insights of international experts. The resultant consensus was included in the contents of the standard protocol of MII-pH. The standard protocol included standardization of the indication, methodology, and interpretation of MII-pH in Japanese children. The criteria for abnormal GER by MII-pH were defined using the Reflux Index and number of total reflux episodes independently in children aged < 1 year and those aged ≥ 1 year. Moreover, a significant relationship between GER and symptoms was identified using the symptom index and symptom association probability approach. We conclude that the current version of the protocol for MII-pH is tentative because it is not based on data from Japanese children. Further studies are needed to render this protocol clinically beneficial and expand its use in Japan.

Abstract
INTRODUCTION Resting energy expenditure (REE) is expected to be lower in with severe motor and intellectual disabilities (SMID) patients than in healthy subjects because of their relatively low fat-free mass (FFM). Therefore, an REE predictive equation for SMID patients may be required. The aim of this study was to validate existing REE predictive weight-based equations (Harris-Benedict, WHO, Mifflin, Owen, Schofield) and FFM-based REE equations (Mifflin, Owen and Cunningham) and to develop a new SMID patient-specific FFM-based REE equation. METHODS Twenty-eight (22 males, 6 females) SMID patients over 18 years of age were included. The REE was measured using indirect calorimetry. FFM were measured using bioelectrical impedance analysis. A multiple linear regression analysis was used to develop a new FFM-based REE predictive equation. The accurate predictions compared the measured REE and root mean square error. RESULTS The median measured REE was 950 (25th,75th percentile:712.75, 1102.75) kcal/day. The new FFM-based equation was as follows: REE (kcal/day) = 550.62 + 16.62 FFM (kg). The new FFM-based REE resulted in the highest percentage of accurate predictions within 10% of measured REE (42.9%). The root mean square errors were the smallest for the new FFM-based REE and largest for Harris-Benedict (91.00 and 185.22 kcal/day). CONCLUSION For SMID patients, the REE cannot accurately be predicted using the existing weight-based REE equations. Furthermore, the existing FFM-based REE equations are less accurate with regard to the measured REE than the new FFM-based REE equation. The new FFM-based equation is advised for use in SMID patients.

Abstract
INTRODUCTION Lipoblastoma is a rare benign soft tissue tumor that occurs most commonly in infants and children. However, retroperitoneal lipoblastomas are rare, occurring in <5% of cases. We report a case of large retroperitoneal lipoblastoma and the largest collection of known retroperitoneal lipoblastomas in children in the literature. CASE PRESENTATION A 3-year-old girl presented with left abdominal mass. Magnetic resonance imaging (MRI) revealed a soft tissue mass measuring 12 × 8 × 6 cm in the retroperitoneal region. The mass had a clearly defined margin and a reticular pattern with an interposing fat component. Based on these findings, the mass was suspected to be a soft-tissue tumor, most likely lipoblastoma.Laparotomy with resection of the retroperitoneal mass was performed. The tumor was easily dissected from the retroperitoneal space without injury to surrounding structure.A histopathological examination demonstrated the mature proliferation of adipocytes and spindle-shaped cells separated by fibrovascular septa accompanied by myxoid changes. The cells were separated into lobules by septa, and areas of immature adipocytes showing a signet-ring or multivacuolar appearance were present at the periphery. Histopathological diagnosis was lipoblastoma. Follow-up at 6 months revealed no evidence of recurrence. CONCLUSION Retroperitoneal lipoblastoma is rare and tends to be large in size when diagnosed at presentation. Complete resection should not be delayed, as impingement on the surrounding structures is imminent.

Abstract
The finding that dendritic cells (DCs) orchestrate innate and adaptive immune responses has stimulated research on harnessing DCs for developing more effective vaccines for DC therapy. The expression of cytomegalovirus (CMV) antigens in glioblastoma multiforme (GBM) presents a unique opportunity to target these viral proteins for tumour immunotherapy. Here, we demonstrate that Vγ9γδT cells, innate immune cells activated by zoledronate (Z) and Vα24 natural killer (Vα24NK) cells, innate/adaptive immune cells activated by α‐galactosylceramide (G) can link innate and adaptive immunities through cross‐talk with interferon (IFN) DCs from patients with glioblastoma multiforme (GBM) and healthy donors in a manner that can amplify the activation and proliferation of CMVpp65‐specific CD8+ T cells. The IFN DCs derived from patients with GBM used in this study express lower levels of programmed cell death ligand (PD)‐L1 and PD‐L2 and higher levels of C‐C receptor 7 (CCR7) than the most commonly used mature interleukin (IL)‐4 DCs. The expression level of programmed cell death 1 (PD‐1) on CD8+ T cells, including CMVpp65‐specific CD8+ T cells, expanded by IFN DCs pulsed with the CMVpp65‐peptide and Z plus G (IFN DCs/P+Z+G), was lower than that expanded by IFN DCs pulsed with the peptide alone (IFN DCs/P). Multi‐functional T cells, including human leucocyte antigen (HLA)‐A*0201‐restricted CMVpp65‐specific CD8+ T cells, Vγ9γδT cells and Vα24NKT cells, efficiently kill the HLA‐A*0201‐positive GBM cell line expressing CMVpp65 protein (T98G). These findings indicate that DC therapy using IFN DCs/P+Z+G and/or CTL therapy using CMVpp65‐specific CD8+ T cells expanded by IFN DCs/P+Z+G may lead to a good clinical outcome for patients with GBM.

Abstract
The aims of this study were to evaluate the efficacy of partial parotidectomy using retrograde dissection of the marginal mandibular branch of the facial nerve for benign tumours of the parotid gland and to establish the indications for its use. We examined 106 consecutive patients with previously untreated benign tumours in the lower portion of the parotid gland who were treated by parotidectomy. The first group (anterograde group, n=52) consisted of those who had standard anterograde parotidectomy. The remaining patients, who underwent retrograde parotidectomy, were further divided into two groups: those in whom the upper edge of the tumour was located below the mastoid tip (below mastoid group, n=46) or those in whom it was above the mastoid tip (above mastoid group, n=8). The operating time was significantly shorter in the below mastoid group (141.2, 127.5, and 98.1minutes, respectively) as was intraoperative blood loss (41.1, 53.0, and 24.4ml, respectively), compared with the other two groups. There was a higher incidence of facial nerve dysfunction in the above mastoid group postoperatively (4/8) than in the other two groups. The results suggested that the presence of a tumour of any size located below the mastoid tip is a good indication for parotidectomy using retrograde dissection of the marginal mandibular branch of the facial nerve.

Abstract
BACKGROUND The present study aimed to evaluate the characteristics associated with a number of reflux episodes (NoRE) of 70 by comparing the clinical and multichannel intraluminal impedance pH measurements (pH/MII) and pH index (pHI) in neurologically impaired (NI) children. PATIENTS AND METHODS NI children (1-16 years of age) in whom pH/MII had been measured for GERD study were enrolled in this study. All children were divided into NoRE >70 or ≤70 and pHI >4.0 or ≤4.0, >5.0 or ≤5.0 or >7.0 or ≤7.0. In addition, the NI children with pHI >4.0, >5.0 and >7.0 were subdivided into NoRE >70 and ≤70 groups. The clinical and pH/MII measurements were compared between each of the two groups. The cutoff values of pHI and baseline impedance (BI) (Z6) were calculated to discriminate NoRE >70 and ≤70. RESULTS A total of 61 NI children were enrolled in this study. There was a significant difference in the acid-related parameters, the NoRE (nonacid) and BI between NoRE >70 and ≤70, acid-related parameters and BI between pHI >4.0 and ≤4.0, >5.0 and ≤5.0 and >7.0 and ≤7.0 groups. Furthermore, a significant difference was still observed in the BI between NoRE >70 and ≤70 groups among patients with pHI >4.0, >5.0 or >7.0. The cutoff values of pHI and BI (Z6) for discriminating NoRE >70 and ≤70 were 9.2 and 1049Ω, respectively. CONCLUSION The present study indicates that NoRE 70 corresponds to GERD in which patients suffer severe acid exposure with pH of around 9% and esophageal mucosal damage with low BI value in NI children.

Abstract
BACKGROUND Anterior sagittal anorectoplasty (ASARP) has been a standardised operative treatment for anorectal malformation (ARM). This retrospective study was undertaken to evaluate patients with perineal fistula (PF) and vestibular fistula (VF) treated by ASARP in our institution. PATIENTS AND METHODS Twenty patients (PF, n = 14; male, n = 8 and female, n = 6 and VF, n = 6) were evaluated. Eighteen patients underwent primary ASARP without protective colostomy. Two patients underwent colostomy because of intestinal atresia and suspected of other type ARM. The age range of operation was from 4 months to 5.0 years. Sixteen patients (PF, n = 13; male, n = 7 and female n = 6 and VF, n = 3) over 3 years of age were evaluated according to the Krickenbeck classification. RESULTS Operative complications occurred in one patient. Minor wound dehiscence occurred in six patients. Mucosal prolapse occurred in two patients. According to the Krickenbeck classification, amongst male patients with PF, all patients had voluntary bowel movements (VBMs) and two patients had Grade 1 soiling, while four patients had Grade 2 constipation. Amongst female patients with PF, all patients had VBM and no soiling, one patient had Grade 1 and two patients had Grade 2 constipation. In patients with VF, one patient was continent with Grade 1 soiling. One patient had Grade 2 and two patients had Grade 3 constipation. CONCLUSIONS ASARP without colostomy carried a risk of wound dehiscence. The ASARP technique provided normal or moderate outcomes for VBM and soiling. However, in about half of patients, defecation management with laxative therapy was required to achieve a normal condition.

Abstract
Background/Aims The aim of this study is to investigate the degree of delayed gastric emptying (DGE) and evaluate how the severity of DGE affects gastroesophageal reflux disease (GERD) in neurologically impaired (NI) patients utilizing 24-hour multichannel intraluminal impedance pH measurements (pH/MII) and 13C-acetate breath test (13C-ABT) analyses. Methods 13C-ABT and pH/MII were conducted in 26 NI patients who were referred to our institution due to suspected GERD. At first, correlation analyses were performed to investigate the correlation between the 13C-ABT parameters and the clinical or pH/MII parameters. Thereafter, all patients were divided into 2 groups (DGE and severe DGE [SDGE] group) according to each cut off half emptying time (t1/2, 90-170 minutes). Each pH/MII parameter was compared between the 2 groups in each set-up cutoff t1/2. Results The mean t1/2 of all patients was 215.5 ± 237.2 minutes and the t1/2 of 24 (92.3%) patients were > 100 minutes. Significant moderate positive correlations were observed between both t1/2 and lag phase time and the non-acid reflux related parameters. Furthermore, the patients in the SDGE group demonstrated higher non-acid reflux related parameters than those of the DGE groups when the cutoff was t1/2 ≥ 140 minutes. Conclusion The present study demonstrated that GE with t1/2 ≥ 140 minutes was related to an increase of non-acid exposure reaching up to the proximal esophagus in NI patients, and indicating that NI patients with SDGE might have a high risk of non-acid GERD.

Abstract
PURPOSE The aim of the present study was to determine the utility of measuring the salivary pepsin level (SPL) as an objective assessment of gastroesophageal reflux disease (GERD) in severe motor and intellectual disabilities (SMID) patients. SUBJECTS AND METHODS This prospective study included 26 SMID patients who underwent simultaneous 24-h multichannel intraluminal impedance pH measurement (pH/MII) and SPL evaluation. The enrolled patients were divided into GERD (+) or GERD (-) groups according to the pH/MII findings. The age, gender and pH/MII parameters were compared between the two groups. A correlation analysis was also conducted for the SPL following early-morning fasting and post-enteral feeding and the age, gender, presence of gastrostomy and tracheostomy and pH/MII parameters. The SPL was compared between the two sampling groups. RESULTS Fifteen patients were classified as GERD (+), and 11 patients were classified as GERD (-). The mean SPL following early-morning fasting and post-enteral feeding among all patients were 104.3 (median: 38, 25th and 75th percentile: 12, 361) ng/ml and 222.2 (median: 152:0, 500) ng/ml, respectively. Regarding positivity, 76.9% and 73.1% of SPL values in early-morning fasting and post-enteral feeding SMID patients, respectively, were positive (≧16ng/ml). The SPL following early-morning fasting demonstrated a weak but significant positive correlation with age. In contrast, we noted no correlation between the pH/MII parameters and the SPL for either the early-morning fasting or post-enteral feeding patients, and no significant difference in the SPL was observed between the GERD (+) and (-) patients. CONCLUSIONS The present study showed that a high proportion of SMID patients had a relatively high SPL, regardless of the presence of GERD. The SPL in SMID patients might be affected by several distinctive factors in addition to gastroesophageal reflux.

Abstract
PURPOSE The purpose of the present study was to evaluate whether evaluating the phase angle (PhA), in a bioelectrical impedance analysis (BIA) is useful for estimating the nutritional status of severe motor and intellectual disabilities (SMID) patients. SUBJECTS AND METHODS This retrospective study included 31 SMID patients (mean age: 33.9±13.5years, median age: 29years (range: 18-58years), male/female: 23/8). First, each of the parameters from the total study population and the male and female SMID patients were compared with those of healthy Asian subjects. Second, correlation analyses were conducted to investigate the correlation between the PhA and the other BIA parameters (appendicular skeletal muscle mass index (ASMI), appendicular muscle mass (AMM), extracellular water (ECW)/total body water (TBW)) as well as subjective global assessment and serum nutritional markers. Finally, all patients were divided into 2 groups according to their albumin (Alb) (<3.5 or ≥3.5) values and PhA of the 2 groups were compared. RESULTS The mean PhA and ASMI were a considerably low, whereas ECW/TBW was considerably high in comparison to the healthy Asian subjects. Significant negative correlations were observed between the PhA and ECW/TBW, whereas there were significant positive correlations between PhA and AMM, ASMI, total protein and albumin levels. Furthermore, PhA of Alb ≥3.5 group was significantly higher than that of Alb <3.5 group. CONCLUSIONS The present study indicated that SMID patients demonstrate the low PhA, which were similar to sarcopenia and a certain proportion of them also potentially have nutritional disturbances.

Abstract
We present a summary of the campaign of remote observations that supported the European Space Agency's Rosetta mission. Telescopes across the globe (and in space) followed comet 67P/Churyumov-Gerasimenko from before Rosetta's arrival until nearly the end of the mission in September 2016. These provided essential data for mission planning, large-scale context information for the coma and tails beyond the spacecraft and a way to directly compare 67P with other comets. The observations revealed 67P to be a relatively 'well-behaved' comet, typical of Jupiter family comets and with activity patterns that repeat from orbit to orbit. Comparison between this large collection of telescopic observations and the in situ results from Rosetta will allow us to better understand comet coma chemistry and structure. This work is just beginning as the mission ends-in this paper, we present a summary of the ground-based observations and early results, and point to many questions that will be addressed in future studies.This article is part of the themed issue 'Cometary science after Rosetta'.
