RESUMO
PURPOSE: Helicobacter pylori (HP) infection, a risk factor for gastric cancer, is prevalent in Japan. Consequently, some municipalities across Japan are implementing HP screening and treatment programs for adolescents. However, little is known about parents' attitudes and awareness regarding HP screening for their children. This study aimed to elucidate parental perspectives on HP screening for their children and identify the factors influencing these attitudes. METHODS: This study focused on the parents of first-year junior high school students in Yokosuka City, Kanagawa Prefecture, where an HP screening and treatment program had been implemented for adolescents. The survey questionnaire was distributed among parents in all 23 public junior high schools in Yokosuka City. RESULTS: Among the 618 respondents, 86.4% supported HP screening for their children. Regression analysis identified sufficient knowledge about HP (adjusted odds ratio (aOR) = 5.80; 95% confidence interval (CI), 2.10-16.03) and being in their 40s (aOR = 2.25; 95% CI, 1.35-3.77) as significant factors influencing supportive attitudes. For parents favoring the screening, common reasons included perceiving it as a promising opportunity (53.2%) and considering the test necessary (44.0%). In contrast, those who opposed screening frequently cited it as unnecessary (66.7%) or believed that their children did not have HP. CONCLUSIONS: A significant proportion of parents in Yokosuka City, Japan, demonstrated a good understanding of HP and expressed a high level of interest in HP screening for their children. Further investigation of parents' attitudes is essential for the effective implementation of adolescent HP screening programs.
RESUMO
Background: Gastroesophageal reflux (GER) disease (GERD) is a condition wherein GER causes troublesome symptoms that can affect daily functioning and/or clinical complications within the esophagus or other systems. To avoid this, patients with GERD often require treatment; hence, it is important to distinguish GER from GERD. Patients with GERD exhibiting alarm signs should be examined early to differentiate it from GER and treated accordingly. Herein, we present a case of GERD caused by a hiatal hernia that required surgical intervention for esophagial cicatrical stenosis despite oral treatment. We also discussed how to choose the appropriate acid suppressants for GERD. Case presentation: A 1-year-old boy was referred to our hospital for repeated vomiting and poor weight gain. He received histamine 2 receptor antagonists (H2RAs) that contributed slightly to the decreased frequency of vomiting and aided weight gain; however, he soon stopped gaining weight and had bloody vomit. His upper gastrointestinal series revealed hiatal hernia, a 24â h impedance pH monitoring test indicated abnormal values for acid reflux, and esophagogastroduodenoscopy (EGD) revealed esophagitis. He was subsequently diagnosed with GERD associated with hiatal hernia. A proton pump inhibitor (PPI) was intravenously administered to him, following which his medication was changed to a potassium-competitive acid blocker (P-CAB). Thereafter, his vomiting episodes significantly decreased and his weight increased. However, 6 months after starting P-CAB, his vomiting episodes suddenly increased in frequency. EGD revealed the presence esophageal stricture due to scarring from GERD. He was then treated via laparoscopic fundoplication, gastrostomy, and esophageal balloon dilation. Thereafter, his vomiting episodes stopped and food intake improved, leading to weight gain. Conclusion: It is essential to identify the cause of GERD early and take an appropriate treatment approach depending on the cause of GERD with alarm signs. Further, as a drug therapy for GERD as a clear acid mediated disease or in children with alarm signs, PPIs or P-CAB should be used from the beginning instead of H2RAs.
RESUMO
Key Clinical Message: Clinicians should not only consider the presence of metallic foreign bodies within the digestive tract but also contemplate the possibility of nicotine poisoning during the diagnostic process. Abstract: When clinicians encounter cases of accidental ingestion of some types of heated tobacco, they must consider not only nicotine poisoning but also the possibility of a metallic foreign body within the digestive tract during diagnosis. In children, even sharp or relatively large ingested foreign bodies can spontaneously pass below the esophagus. Considering that this 12-mm metal piece is small, natural excretion may be considered rather than endoscopic removal.
RESUMO
BACKGROUND AND OBJECTIVES: Niemann-Pick type C (NPC) is a rare lysosomal storage disease characterized by hepatosplenomegaly and progressive neurological deterioration due to abnormal intracellular cholesterol transport. Cyclic oligosaccharide 2-hydroxypropyl-ß-cyclodextrin (HPBCD) is an effective treatment for NPC; however, few reports have shown its long-term efficacy and safety. To demonstrate long-term efficacy and safety of intrathecal HPBCD (IT-HPBCD) treatment for NPC, we herein reports five patients with NPC treated using IT-HPBCD for 4-11 years. CASES AND RESULTS: Patients' ages at the onset ranged from 1.5 to 20 years. Notably, all patients showed rapid disease progression despite treatment with miglustat before IT-HPBCD treatment. Similarly, some patients showed transient improvement; however, all patients' conditions stabilized after long-term IT-HPBCD therapy. Mild-to-moderate hearing loss was observed in three patients. Furthermore, long-term treatment with IT-HPBCD may suppress neurological deterioration in patients with NPC; however, patients still experience some disease progression. CONCLUSIONS: Long-term treatment with IT-HPBCD may suppress neurological deterioration in patients with NPC; however, the treatment outcome is dependent on the neurological status at the time of diagnosis, and disease progression is not completely inhibited. Awareness of the disease and newborn screening is needed for earlier disease detection. In addition, further optimization of the treatment protocol and additional treatments are needed to improve patient outcomes.

Gastrointestinal bleeding is one serious complication of patients undergoing hemodialysis with end-stage renal failure. The present study aimed to evaluate risks and clinical features of real-world clinical data on upper and lower gastrointestinal bleeding in patients undergoing hemodialysis during a 5-year longitudinal observation period. This study included 151 patients undergoing maintenance hemodialysis at Takagi Hospital between December 2017 and December 2022. Clinical data from December 2017 were recorded, and upper and lower gastrointestinal bleeding, mortality, prescribed medications, and bone fractures were examined during the five-year observation period. Of 151 patients, 32 (21.2%:4.2% per year) experienced bleeding, 24 had upper gastrointestinal bleeding, 7 had lower gastrointestinal bleeding, and one had an unknown origin of bleeding. Ulcers or erosions primarily cause upper gastrointestinal bleeding without Helicobacter pylori infection, whereas patients with H pylori eradication are more likely to experience bleeding caused by vascular lesions, often accompanied by underlying comorbidities. The prophylactic effects of proton pump inhibitors and histamine-2 receptor blockers were limited in hemodialysis patients, as 15 out of 24 patients with upper gastrointestinal bleeding (62.5%) were prescribed these medications. The mortality rate in patients with lower gastrointestinal bleeding (71.4%) was higher than that in those without bleeding (33.6%) (Pâ <â .05). All patients with lower gastrointestinal bleeding were prescribed nonsteroidal anti-inflammatory drugs and/or aspirin. In this study, endoscopic hemostasis was successfully achieved. The present study indicated that the incidence of gastrointestinal bleeding during hemodialysis was relatively high. Upper gastrointestinal bleeding may develop even with the prescription of proton pump inhibitors. Lower gastrointestinal bleeding was a complication in hemodialysis patients under serious pathological condition with nonsteroidal anti-inflammatory drugs and or aspirin.

Helicobacter pylori is a commonly encountered pathogen in medical practice. It causes chronic gastritis in patients of different ages. Many published papers have provided different opinions on whether the test-and-treat strategy for H. pylori infection should be implemented in children. It is critical that the opinion in favor of this strategy was published in Europe, where ESPGHAN/NASPGHAN guidelines have not recommended the use of test-and-treat strategy for H. pylori in children. Herein, I propose my opinion regarding this debate using 4 main points. First, this strategy should be implemented in areas where its benefits outweigh the associated risks. Thus, if it is not tailored to the locality, the results of the test-and-treat strategy for H. pylori in children may be erroneous. Second, the association between H. pylori infection and other diseases such as asthma and other allergic diseases should not be factored in when considering the test-and-treat strategy. This is because these diseases are associated with H. pylori noninfection and not with its posteradication status. Third, there is evidence that H. pylori infection can significantly alter children's intestinal microbiota. Finally, gastroscopy should not be performed in all H. pylori-positive children, particularly if the drug susceptibility test is not available. In the near future, it will be possible to easily conduct drug susceptibility tests for H. pylori using fecal samples. I believe that this report may expand the test-and-treat strategy for children infected with asymptomatic H. pylori outside of Japan and prevent not only gastric cancer but also minor diseases such as iron deficiency anemia, chronic idiopathic thrombocytopenic purpura, and failure to thrive. Pediatricians are responsible for keeping children healthy not only during childhood but also in adulthood. Thus, even if there are only a few H. pylori-related diseases and no severe cases in children, it is necessary to take early measures to prevent problems (eg, incidence of gastric cancer) in adulthood.

As society ages, the number of patients with spinal degenerative diseases (SDD) is increasing, posing a major socioeconomic problem for patients and their families. SDD refers to a generic term for degenerative diseases of spinal structures, including osteoporosis (bone), facet osteoarthritis (joint), intervertebral disk degeneration (disk), lumbar spinal canal stenosis (yellow ligament), and spinal sarcopenia (muscle). We propose the term "gut-spine axis" for the first time, given the influence of gut microbiota (GM) on the metabolic, immune, and endocrine environment in hosts through various potential mechanisms. A close cross-talk is noted between the aforementioned spinal components and degenerative diseases. This review outlines the nature and role of GM, highlighting GM abnormalities associated with the degeneration of spinal components. It also summarizes the evidence linking GM to various SDD. The gut-spine axis perspective can provide novel insights into the pathogenesis and treatment of SDD.
RESUMO
RATIONALE: Juvenile polyps (JPs) are the most common polyp type and can be observed in 1% of all preschoolers. The peak incidence is observed at ages 3 to 5 years, constituting 90% of all polyps in children. Elevated levels of fecal calprotectin (FC) are often seen in children with JPs. PATIENT CONCERNS: A 15-month-old girl was referred to our hospital for blood on the stool surface persisting for 3 months. She was healthy, with no abdominal pain, diarrhea, anorexia, or weight loss and no complaints other than hematochezia. Her physical examination, vital signs and laboratory date were unremarkable. DIAGNOSIS: JPs. INTERVENTION: Total colonoscopy for her found 2 JPs in the sigmoid colon, which were subsequently resected endoscopically. OUTCOMES: At the age of 5 years, this patient again had bloody stools. Her FC measurement at that time was 1020 mg/kg, which normalized to 42 mg/kg 3 months after her second resection. LESSONS: Single or multiple solitary JPs require follow-up that fully considers the possibility of recurrence. Establishing a method for early confirmation of JP recurrence based on bloody stools, fecal occult blood testing, and FC measurement is necessary.

The urea breath test (UBT) is often used to diagnose Helicobacter pylori infection and for its eradication. However, this text can give positive results even for other urease-active bacteria other than H. pylori. Even after the successful eradication of H. pylori, the presence of other urease-active bacteria in the gut and oral cavity can lead to positive UBT results in patients with decreased gastric acid secretion. Herein, a 15-year-old boy was diagnosed with H. pylori infection through the testing and treatment program for H. pylori for third-year junior high-school students in Saga Prefecture initiated in 2016. He underwent triple therapy comprising vonoprazan; however, UBT was found to be positive even after therapy. The results remained positive even after fourth-line eradication therapy. Stool antigen, PCR using gastric fluid, microscopy, culture, and rapid urease tests were all negative. Pepsinogen levels were normal, and none of the findings suggested autoimmune gastritis. Gastric microflora analysis revealed oral flora showing urease activity. UBT is considered useful for determining the successful eradication of H. pylori; however, it may give false-positive results for both H. pylori infection and eradication judgment. Although the patient did not have autoimmune gastritis or decreased gastric acid secretion, it is presumed that oral commensal bacteria showing urease activity inhabited the stomach, resulting in the persistently positive UBT results. In conclusion, repeated false-positive UBT results for H. pylori may occur even without gastric acid hyposecretion. If H. pylori eradication is unsuccessful based on UBT, additional test by stool H. pylori antigen tests should be considered.
RESUMO
In this study, we compared the success rate of eradicating Helicobacter pylori (H. pylori) in adults and children using vonoprazan (VPZ)-based H. pylori regimens to that of proton pump inhibitors (PPIs). In Japan, the success rate of a VPZ-based regimen as first-line therapy was lower in children than in adults. Compared with adults, children around puberty have higher CYP2C19 and CYP3A4 enzymatic activity to metabolize PPIs and VPZ. Further, children generally have shorter intestinal transit times than adults and may absorb antibiotics to a lesser extent. When comparing success rates of pediatric and adult eradication therapy using VPZ, it is very important to maintain a higher intragastric pH with sufficient gastric acid suppression to maintain H. pylori in a replicating state and amoxicillin and clarithromycin in the intestinal tract for as long as possible by reducing diarrhea as a side effect. Based on the above, it is reasonable that VPZ, which can suppress stomach acids more strongly than PPI, is a more relevant H. pylori eradication therapy.
RESUMO
Prostaglandin E-major urinary metabolite (PGE-MUM) is a urinary biomarker reflecting ulcerative colitis (UC) activity. This prospective observational study aimed to evaluate the usefulness of PGE-MUM via rapid chemiluminescent enzyme immunoassay in detecting endoscopic remission (ER) and histologic remission (HR) in pediatric UC (6-16 years) in comparison with fecal calprotectin (FCP). ER and HR were defined as Mayo endoscopic score (MES) of 0 and Matts' histological grades (Matts) of 1 or 2, respectively. A total of 104 UC and 39 functional gastrointestinal disorder (FGID) were analyzed. PGE-MUM levels were significantly higher in the UC group than in the FGID group (P < 0.001). FCP levels were significantly elevated in the group without ER and HR than in the group with ER and HR (P < 0.001 and P = 0.001), whereas PGE-MUM levels were significantly higher in the group without ER compared to the group with ER (P < 0.001). No significant differences were noted in the AUCs for PGE-MUM and FCP in detecting ER and HR. Although PGE-MUM was inferior to FCP for the detection of HR, it might have the potential for application as a biomarker of endoscopic activity in pediatric UC owing to its noninvasive and rapid method.

Invasive treatment might be taken into consideration at the time of initial acute pancreatitis in patients with pancreas divisum who do not complain of abdominal pain to prevent progression to chronic pancreatitis.
RESUMO
Foreign body ingestion is one of the common problems among children. A three-year-old girl presented to the emergency department 2 h after ingesting three small disk-type neodymium magnets. She had no gastrointestinal symptoms. Abdominal radiography revealed a foreign body in the left upper quadrant, which was the three circular magnets. Fluoroscopy was performed. She was placed in the right lateral decubitus position for 3 min and slowly returned to the supine position. Abdominal fluoroscopy revealed a foreign body migrating near the middle of the spine. Similarly, when she was placed in the left lateral decubitus position for 3 min and slowly returned to the supine position, the foreign body migrated to the outermost part of her left upper quadrant. Thus, we anticipated that the magnets could be excreted spontaneously. The patient did not develop any gastrointestinal symptoms after returning home, and two days later, three overlapping magnets were finally found in her stool. During accidental ingestion of single or multiple desk-type neodymium magnets, endoscopic removal may not be necessary if they are mobile and clump together in the stomach. Regarding the ingestion of multiple desk-type neodymium magnets, fluoroscopy is useful to determine the extent of endoscopic intervention.
